Changing progressbar level
I have a simple activity that is suppose display a progress bar with
different fill levels. This activity with the progress bar is display
after a student undertake a practice test on my mobile application. So the
progess bar would show if the student passed showing all blue with the
color filling it. if it is an average performance. The color is half
filled in green. If it is a poor performance the color is completely red
with a slight color fill.
My little code to set fill color is below but it not working
if(grade.equals("passed")){
setProgress(100);
}
else{
setProgress(50);
}

how to undo hijacked files in clearcase?
how to undo hijacked files in clearcase?
I have this strange hijacked file in my snapshot view. when I undo it, it
doesn't go away. Is there a way to un-hijack it. I already tried
undo-hijacked but didn't work. I should see .keep file if it unhijacked
but didn't see any. Also tried to check out and uncheck out but this file
still remains as hijacked.
Thanks for any help !!

Multiple Variable Assignment from Single Hash Ruby
Multiple Variable Assignment from Single Hash Ruby
Hello All This seems like a day 1 question, And I feel like I've had it
working before, but for some reason I'm at a loss. But I'm trying to have
an Array assign a value to two variables.
test = "hello, my,name,is,dog,how,are,you"
testsplit = test.split ","
testsplit.each do |x,y|
puts y
end
I would think that it would print my is how you
but it appears the values only get passed to x and not to y. When i run
this code y comes back as empty.

How to pass an ID from a repeater row to a nested gridview?
How to pass an ID from a repeater row to a nested gridview?
QUESTION
If you have a gridview inside a repeater, how do you pass a primary key ID
to the gridview where the primary key relates to the repeaters item
template row?
I am currently attempting to do this by using a hiddenfield that contains
the PK and a control parameter to detect it and bind it to the gridview.
CURRENT ERROR
Could not find control 'hidPK' in ControlParameter 'PK'.

Spring Data REST: Silent failure when adding entity relationship
Spring Data REST: Silent failure when adding entity relationship
Fellow Spring Data REST enthusiasts, I am running my Spring Data REST 1.1
application, and I am attempting use curl to add an entity relationship
using the "text/uri-list" Content-type, as described in the link:
Example-API-usage-with-curl.
curl -v -d "http://localhost:8080/simplemvc/rest/enemies/3" -H
"Content-Type: text/uri-list"
http://localhost:8080/simplemvc/rest/heroes/1/defeatedEnemies
Unfortunately, although the server returns "201 Created", the body
contains an empty JSON object, and the entity relationship does not get
created:
{
"links" : [ ],
"content" : [ ]
}
I would expect to see a SQL UPDATE being executed, but analyzing the SQL
reveals that only SELECT statements occur:
Hibernate: select hero0_.HERO_ID as HERO1_1_0_, hero0_.name as name2_1_0_
from HERO hero0_ where hero0_.HERO_ID=?
Hibernate: select defeateden0_.HERO_ID as HERO4_1_1_,
defeateden0_.ENEMY_ID as ENEMY1_0_1_, defeateden0_.ENEMY_ID as
ENEMY1_0_0_, defeateden0_.description as descript2_0_0_,
defeateden0_.HERO_ID as HERO4_0_0_, defeateden0_.name as name3_0_0_ from
ENEMY defeateden0_ where defeateden0_.HERO_ID=?
Hibernate: select enemy0_.ENEMY_ID as ENEMY1_0_1_, enemy0_.description as
descript2_0_1_, enemy0_.HERO_ID as HERO4_0_1_, enemy0_.name as name3_0_1_,
hero1_.HERO_ID as HERO1_1_0_, hero1_.name as name2_1_0_ from ENEMY enemy0_
left outer join HERO hero1_ on enemy0_.HERO_ID=hero1_.HERO_ID where
enemy0_.ENEMY_ID=?
Interestingly, if I "manually" add a relationship by executing a SQL
statement in my database client:
UPDATE ENEMY SET HERO_ID = 1 WHERE ENEMY_ID = 1;
and then execute the curl statement:
curl -v -H "Accept: application/json"
http://localhost:8080/simplemvc/rest/heroes/1/defeatedEnemies
I get a JSON representation that demonstrates -- via hypermedia links --
that Spring Data REST recognizes the one-to-many relationship between the
Hero and Enemy entities:
{
"links" : [ ],
"content" : [ {
"name" : "Red Ghost",
"description" : "Likes to chase",
"links" : [ {
"rel" : "self",
"href" : "http://localhost:8080/simplemvc/rest/enemies/1"
}, {
"rel" : "enemy.enemy.hero",
"href" : "http://localhost:8080/simplemvc/rest/enemies/1/hero"
} ]
} ]
}

On success of ajax post, how to send a POST request with JQuery .load() method
On success of ajax post, how to send a POST request with JQuery .load()
method
After a successful Ajax post, I would like the template associated with
POST in the handler to be rendered with JQuery's .load() method. The GET
request keeps getting called after a successful POST ...so the template
associated with GET is getting rendered instead of the one associate with
POST. Thanks for any hints you can give.
Javascript:
$(function() {
$(".topic_submit").click(function() {
var topic = $("#topic").val();
refresh = 'false'
$.ajax({
type: "POST",
url: "/mentorlist",
data: {'topic': topic},
success: function(dataString) {
$('#mentor_list').load('/mentorlist');
console.log('**mentor_list div updated via ajax.**');
}
});
return true;
});
});

$$\int_{2} ^{4}u^{-2}du$$
$$(-1)u^{-1} |_{2}^{4}$$
$$-\dfrac{1}{lnx}|_{2}^{4}$$

However the answer in the back of my textbook says that the answer is

see what I did wrong. Could someone please explain what's wrong here?

Hotkey control keycodes confusion
Hotkey control keycodes confusion
HKM_GETHOTEKY returns virtual key code and modifiers but they're not the
same as the ordinary virtual key codes? What is the purpose of HOTKEYF_EXT
and how do i use it?
If i press F5 the hotkey control returns 0x74 which is VK_F5, but when i
press the right arrow key, it returns 0x27 which is VK_RIGHT and the
HOTKEYF_EXT bit is set on the modifier. If i use HKM_SETHOTKEY with
VK_RIGHT as virtual key and no modifiers, it shows "Num 6"
I find this very strange and I need to be able to pass any virtual keys to
the hotkey control window, and therefore i need to understand this
HOTKEYF_EXT modifier.

bash backup script error

Forward Declaring enum class not working
Forward Declaring enum class not working
In State.h I have
namespace States

enum class ID : unsigned int;
}
In State.cpp I have
namespace States
{
enum class ID : unsigned int
{
NullID = 0,
MainMenuID,
GamePlayID,
}
}
The problem is that any class that includes State.h has the forward
declaration, but I can't use any actual enum within a cpp file, like
States::ID::MainMenuID . The error says...
/home/lee/Projects/SuddenAwakening/Source/Game.cpp:24: error: 'MainMenuID'
is not a member of 'States::ID'
I'm running LinuxMint15KDE, g++ 4.7, and I am using c++11 features in
other parts like nullptr, unique_ptr, ect..., so it's not that I forgot
the compiler flag for c++11.

printed twice for single checkin.
Can anyone please help me to solve the issue such that the value has to be
printed once for single checki.

how to use json array key to javascript variable
how to use json array key to javascript variable
i am try json_encode($updateArray);
and this is call by ajax and after ajax success
return me json string on responseText something like this type
{"title":"superAdmin","id":"50"}
now i want to use this two key
like
var text = title;
var id = id;
who can i user this two to as diff. variable.
thanks.

Clarification on simulation engine for real time multiplayer network game
Clarification on simulation engine for real time multiplayer network game
I've been doing some reading about the various forms of multiplayer that
exist today. In a nut shell, I believe the industry standard way involves
the following:
Running the physics for each client on the client machine/device
Sending the input data of this physics to the server (could be another
client running a 'server' session along with their own client data)
Server processes this data to determine if the client is making legitimate
moves, and if not, forces the client to sync to it's instructions (Rubber
banding).
Server forwards historic data from other clients to each client for
simulation.
Effective result from each clients perspective, is playing themselves in
the present, while seeing the other clients in the past.
Hit detection is performed on the server by 'rewinding' the game state to
see if at the time stamp an event occurred, where the affected players
were at that point in time.
Presently, I use a pure dead-reckoning system. Inputs are collected from
each client and physics calculated on each client. This works, however
units quikcly get out of sync and rubber band because the dependency on a
players previous position/speed/orientation is not high enough. AKA: they
are free to change directions and speed quickly and often.
With that being said, how do I solve this?
Is my client simulator effectively supposed to collect several data points
for each player and interpolate the rendering between those nodes? (IE:
each client has multiple data points about all the other clients historic
positions).
As such, my client's simulator drawing player B, would have positions X0,
X1, X2, X3 in a queue at time 0. Between the transition of Time 0 -> Time
1, I know the starting relevant values (location, speed, orientation, etc)
and where he should be come Time 1.
Is the solution to interpolate these values between these known historic
times and data points?
Thanks!

compareTo and insert sort
compareTo and insert sort
Not only am I new to programming, but sorting algorithms as well. I am in
an algorithm and design analysis class so I am understanding the concepts
better because of that... until this problem.
My insert sort will not work. Because this is generic I have to do a lot
comparing it seems (or maybe that is just the way I wrote the code). So,
it gives me this error on the temp = list[i] and also in my while loop
"Operator > cannot be applied to operands of type T and int and Cannot
implicitly convert type T to int. Can someone please explain to me why the
compareto I used did not solve this problem. Also, please explain in
detail so I can learn it. Am I needing to compare both temp and j? I could
not figure that out.

Not only am I new to programming, but sorting algorithms as well. I am in
an algorithm and design analysis class so I am understanding the concepts
better because of that... until this problem.
My insert sort will not work. Because this is generic I have to do a lot
comparing it seems (or maybe that is just the way I wrote the code). So,
it gives me this error on the temp = list[i] and also in my while loop
"Operator > cannot be applied to operands of type T and int and Cannot
implicitly convert type T to int. Can someone please explain to me why the
compareto I used did not solve this problem. Also, please explain in
detail so I can learn it. Am I needing to compare both temp and j? I could
not figure that out.

How to make a button trigger a select drop down options
How to make a button trigger a select drop down options
Im wondering is there is any possible way to link an object to a / tag? I
have a select with three options and I would the users to trigger the
option choices by clicking on an external button?
At this point, I have my select options button, which when I click on,
displays the three optionsin a drop down.
How to make a click on another button opens this three options drop down
as well? Any example would be great!
thank you very much

Mahout - Recommender Evaluator Returns 0.0
Mahout - Recommender Evaluator Returns 0.0
Alright, I'm VERY new to Mahout and java. I'm trying to evaluate a
recommender and the code below returns 0.0 EVERY TIME, no matter the
distance measure or cluster size I use. Clearly, it's not splitting the
training and testing data at all, and I'm not sure why.
Any help with this code is appreciated!
public class Example {
public static void main(String[] args) throws Exception {
final DataModel model = new FileDataModel(new File("FILENAME")) ;
RecommenderEvaluator evaluator = new
AverageAbsoluteDifferenceRecommenderEvaluator();
RecommenderBuilder recommenderBuilder = new RecommenderBuilder() {

ClusterSimilarity clusterSimilarity = new
NearestNeighborClusterSimilarity(similarity);
TreeClusteringRecommender tree = new

Assembly Code Optimization
Assembly Code Optimization
I have experience programming with C and C++ but i am totally new to
assembly coding. The first assembly code i wrote, failed to beat the
compiler optimization. I have a couple of questions regarding assembly
coding. Would really appreciate if i can get answers to this.
Q1> Is it a good idea to push stuff on stack now and then?
Q2> Is it better to do register transfers than to push them on stack and
re-use it?
Q3> Is loading a value in register and re-using it better than using the
value directly?
Q4> Is it a good idea to put loops in assembly to reduce code size?
Thanks!

How to moniter memory allocated by some java method at runtime
How to moniter memory allocated by some java method at runtime
I am creating a java program in which my class suppose A has it's some
predefined behavior. But user can over-ride my class to change its
behavior. so my script will check if there is some subclass than i will
call it's behavior but what if he has written some blocking code or memory
leek in his code. This may harm my process. is there is any way in java to
moniter memory allocated by some method.
Please suggest.

Javascript regex matching literal \\n
Javascript regex matching literal \\n
Stumbled on this little oddity today, can someone explain?
x = 'a \\n b';
x.replace(/\\n/g, '<br>'); // => "a <br> b"
x.replace(RegExp('\\n', 'g'), '<br>'); // => "a \\n b"
x.replace(RegExp('\\n', 'gm'), '<br>'); // => "a <br> b"
I assumed /\\n/g and RegExp('\\n', 'g') would be equivalent, but that
doesn't seem to be the case. In what cases will using one method over the
other give different results?
Why is the multiline flag needed, and only when using a RegExp object?

this.Measure(sz);
this.Arrange(new Rect(new

PHP adding to sessions
PHP adding to sessions
I am making an online quiz, in this quiz, one question is asked at a time.
If the answer is correct, I want to add that point, to the total score
earned. I want the $_SESSION to show how many points the user has earned
so far. The code I have so far is this:
$sql = "SELECT * FROM quiz_questions WHERE Question='$question' AND
Answer='$answer'";
$result = mysql_query($sql);
$num_rows = mysql_num_rows($result);
if ($num_rows != 0){
$score++;
$total_score += $score;
session_start();
$_SESSION['score'] = $total_score;
} else {
echo "Incorrect";
}
}
I already have $score equal to 0 to start in the beginning of the code.
Thank you in advance for all your help!

Highscores - Best time period for a user
Highscores - Best time period for a user
I have a table which keeps track of data from a game, here is an example
of the table:
id | player_name | date | score | kills
1 | test1 | 2013-01-01 00:00:00 | 10000 | 200
2 | test1 | 2013-01-01 00:01:00 | 12000 | 300
I have a leaderboards for players, it ranks people who gain the most
score/kills, etc. in a certain time period. At the moment I have only got
it so that it ranks players in the previous 24 hours. I am doing this by
selecting the first and last records in a specified time period and then
subtracting them to get the difference.
This is my current query:
SELECT date, score FROM datapoints WHERE player_name = :player AND date =
(SELECT MIN(date) FROM datapoints WHERE player_name = :player AND date >
DATE_SUB(CURDATE(), INTERVAL 24 HOUR))
UNION ALL
SELECT date, score FROM datapoints WHERE player_name = :player AND date =
(SELECT MAX(date) FROM datapoints WHERE player_name = :player AND date >
DATE_SUB(CURDATE(), INTERVAL 24 HOUR))
After subtracting I use the PHP arsort() function to order them and then
display them on the page.
However, I want to add another feature. I want to be able to see the on
which day was the users best day for score/kills.
I have been thinking of how I could possibly do it and one was was using
the above query but having a loop for each day and taking out the best
day, however this probably isn't very efficient and I was wondering, if
there was a better way of doing this?

Updating a single cell (not the entire row) in slickgrid with DataView
Updating a single cell (not the entire row) in slickgrid with DataView
I have a slickgrid (using a DataView) that I'm using to display rapidly
changing values. As far as I know, when a value changes in the underlying
model, the only choice I have is to update the entire row:
dataView.updateItem(rowId, rowData);
Unfortunately, even if certain values haven't changed (i.e. I'm only
updating one cell's value in the entire row), slickgrid repaints the
entire row (I'm using the Chrome dev tools to see what is being rendered).
I also have a implementation of the same UI and here I'm able to paint
individual cells (or groups of cells) that update, and rendering is
roughly 3x as fast. It's not exactly apples-to-apples, but I would like to
be able to limit the amount of painting that occurs if possible,
considering on any given update, generally only one or two cells (on a
long row of data) have changed.

Looking up enum label by value
Looking up enum label by value
I have the following enum in my java android application:
static enum PaymentType

Partial(6),
Refund(7), NoShow(8), Prepay(9), Customer(10), Return(11), Change(12),

private int value;
private PaymentType(int i) {
value = i;
}
public int getValue() {

}
I use this enum alot to find out the integer value of one of these string
labels, for example int i = Lookups.PaymentType.Voucher.getValue();.
How can I do this the other way around? I have an integer value from a
database and I need to find which string that corresponds to.

I have a simple collapsible, made with jquery mobile. How can i disable
the button in the header of the collapsible which is meant to expand

collapse/expand programmatically. The whole thing is meant to prevent the

I have a simple collapsible, made with jquery mobile. How can i disable
the button in the header of the collapsible which is meant to expand
collapse the collapsible? I want to disable it, being still able to

user to collapse/expand in order to have the complete programmatical

Express Middleware to populate a Jade variable for all app.get()'s
Express Middleware to populate a Jade variable for all app.get()'s
I have a Jade file that all of my templates extend called layout.jade. In
it I want to be able to have a logout button if the user is currently
logged in (this is kept track of in req.session).
So layout.jade will have something like,
-if (loggedin)
a.navButton(href="/logout") Log Out
The route for a page would look something like,
app.get("/foo", function(req, res) {
res.render("foo", {loggedin: req.session.isValidUser});
});
The thing is, I don't want to have to populate the loggedin variable
manually in every single route. Is there a way I can use Express
middleware to automatically set some default options for the object sent
to res.render? Or is there a better method to do this?

at the top of the function is not available inside the case block.
But OK. If it's not visible in the case block, I can just declare it. I
changed the first statement in the case block to "OdbcCommand command...".
Now I get an error complaining that I can't declare a variable that is

android broadcastreceiver vs listeners
If you have a Service that frequently (every second or half a second)
sends updates, are there pros/cons to using Broadcasts vs registering
Listeners (an Interface you create) that get stored in some sort of List
in the Service and sending out updates that way?
I'm thinking in terms of memory usage, battery consumption, etc. I know
it's a little bit open ended, however, there's not much in terms of
documentation so they can be equal, but if someone knows a definite answer
or has some input, it would be appreciated.

I have a long table data, which having many of the rows and nested tables.

MySQL exception handler access exception being handled
MySQL exception handler access exception being handled
I'm trying to rollback on an error, but still let the client receive the
error. This might actually be impossible, unless there is a way to access
the error in an exception handler.
It's possible to "throw" from an exception, i.e. it's possible to raise a
signal:
CREATE PROCEDURE p ()
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
SIGNAL SQLSTATE VALUE '99999'
SET MESSAGE_TEXT = 'An error occurred';
END;
DROP TABLE no_such_table;
END;
But this sample code from the MySQL doc looks horrible, because it
literally swallows all errors and jams them into one.
SHOW ERRORS seems relevant, but I don't see any way to work with it
programmatically, e.g. SELECT Code FROM (SHOW ERRORS); is not possible.
Is this possible? Is there a better practice that I'm missing entirely?

I have written a complete website. I have used my own jquery navigation
plugin in it. It works in my localhost, but the hosted version fails to do
so. The problem is reported by the firebug is: mtNav() is not a function.
I don't know what to do. Because the source script of nav plugin is loaded
completely. Here is the URL to the site:
http://www.ms-models.com
Just the third item in the top-navigation should include drop-down menus.
Please ignore the language, just check the third item of nav menu.
Here is the loaded script:

and here is the plugin applied to the navigation bar.
<script type="text/javascript">
$(document).ready(function(e) {

Catching a moment when some specific "laggy" application window finishes processing its keyboard input
Catching a moment when some specific "laggy" application window finishes
processing its keyboard input
I want to show a popup when I get some specific input I into any currently
running application A. Depending on popup's dialog result, I want to
modify the text into application A's current textbox by sending keystrokes
using SendKeys class. I'm currently using low level keyboard hook, which
means I could get keydown events before application A process it. In this
case my popup will be shown before last part of the inputted text appears
in the A's text box. Popup will get the focus and prevent this part of
text from reaching A.
For example, I'm searching for lol keyword. User opens Notepad and inputs
"lol". My application should show popup window "Press Enter to add
blahblahblah text" at this moment. Popup window became foreground. If user
presses Enter, application closes this dialog, makes Notepad foreground
back again and sends "blahblahblah" as a keystrokes to the system.
Everything works fine with the Notepad, but what if target
application/system works slowly and not responding sometimes? Considering
the next test app:
public Form1()
{
InitializeComponent();
timer1.Enabled = true;
timer1.Interval = 2000;
}
private void timer1_Tick(object sender, EventArgs e)
{
Sleep();
}
void Sleep()
{
System.Threading.Thread.CurrentThread.Join(1900);
}
This form contains a textbox and its UI thread is sleeping 95% of the
time. It processing keyboard input each 2 seconds. So if user inputs lol
in such a window, my application most likely will show the popup before
"lol" text appears in the textbox.
I do not want to show my popup before all the text reached the target app A.
Can you please suggest any method of getting the moment when some process
consumed all the keyboard input? SendKeys.Flush() is not working for me.
So does Process.WaitForInputIdle(), which is designed for other purpose, I
suppose. I've tried to send WM_ACTIVATE message via SendMessage to the
target app, because I thought it's exactly what I'm looking for:
The SendMessage function calls the window procedure for the specified
window and does not return until the window procedure has processed the
message.
http://msdn.microsoft.com/en-us/library/windows/desktop/ms644950%28v=vs.85%29.aspx
User32.SendMessage(activeWindow, 6, 1, 0)
call returns 0, but not creating required pause and my popup appears
before the text.
Thanks in advance.

create a .tex (latex) document of his data. Is there a way to compile
these latex documents within my app, so the user gets an pdf from the
latex document?
Thanks.
Escape from Recursion with a Time Limit
Escape from Recursion with a Time Limit
I'm writing a program to play checkers where each move is timed. I am
using alpha-beta pruning to find the best move. I can only go so deep in
the decision tree because:
The decision tree is huge for checkers
There is a time limit I have to decide the move
Is there a way to escape from the call stack instantly when I have run out
of time, even when there are lots of frames on the stack? I thought about
throwing an exception, but that seemed like a poor decision.
This is what I am doing now, but it is not fast enough
public Move play(Board board) {
ArrayList<Board> actions = board.findPossibleMoves();
if (actions.size() == 0) {
return new Board();
}
int depth = 3;
// Each move has 1 second (1000ms)
TimeLimit tl = new TimeLimit(1000);
double alpha = Double.NEGATIVE_INFINITY;
double beta = Double.POSITIVE_INFINITY;
Board bestSoFar = actions.get(0);
double v = Double.NEGATIVE_INFINITY;
for (Board b : actions) {
double result = minValue(b, depth, alpha, beta, tl);
if (result >= v) {
bestSoFar = b;
v = result;
}
if (v >= beta) return b;
alpha = Math.max(alpha, v);
}
return bestSoFar;
}

sending name instead email address usin mailto
sending name instead email address usin mailto
I'm creating an in-office webpage that you can choose the people you want
to sent your mail to with check boxes, and then press a button that will
open outlook and send them an email.
I'm trying to send it with names, instead of email addresses.
Example:
Tomer Amir; John Do; ... etc. And not:
tomer@office.com; john@office.com; ...
the problem is that outlook does not recognizes the names...
my code:
function getSelectedCheckbox(){
var names = "";
$('input[name=checkboxlist]:checked').each(function() {
names += $(this).val();
});
document.getElementById('selectedrows').value = names;
}
function sendMail(){
getSelectedCheckbox();
var mails = document.getElementById('selectedrows').value;
window.open('mailto:'+mails+'?subject=subject&body=body');
}
it returns a string that looks like this:
Tomer Amir; John Do;

NULL TO NOT NULL ALTER TABLE IN SAS
NULL TO NOT NULL ALTER TABLE IN SAS
I'm having difficulties running a SAS Data Intergration job.
One column needs to be removed from the target's structure, but cannot be
removed because of the NULL constraint.
Do I need to remove the constraint first?
How do I do that?
Thank you in advance, Gal.

Laravel - error saving record with one to many relationship
Laravel - error saving record with one to many relationship
Struggling to update my code with laravel relationships.
I have two tables. Customer and Reservations with Customer having a
hasMany relationship with Reservation and Reservation having a belongs to
relationship with Customer.
The reservation table also has a many to many relationship with a product
table via a link table.
I obtain the customer record ok and I now need to create a reservation for
the customer.
I'm assuming the process is: create the reservation object, attach the
reservation to the customer and then link to the product. (the reservation
table has a few relationships but I'll get this working for now)
If I try this code I get an error Field 'customer_id' doesn't have a
default value - the database table allows null and there are no validation
rules set so assume this is to do with the relationship I've set up.
`$reservation = new Reservation;
$reservation->play_date=$play_date->format('Y-m-d');
$reservation->booked_date=$booked_date->format('Y-m-d');
$reservation->am_tee=$am_time->format('H:i:s');
$reservation->pm_tee=$pm_time->format('H:i:s');
$reservation->save();
$customer->reservation()->associate($reservation);`
The error occurs with $reservation->save();
I then need to use the created $reservation to create entries in the
product link table so need to be able to access the newly created
reservation and it's relationship with products.
I can create the entry using $customer->reservation()->save($reservation);
but then I don't seem to have a $reservation object to work with (or do
I?)
I'm very confused by the relationships so grateful for all help to
understand how to get this to work

UIScrollView subclass trigger event
UIScrollView subclass trigger event
I've tried for some days understand Xcode Subclasses and Categories - and
after all I found one event that are fired.
- (void)setContentOffset:(CGPoint)contentOffset {
NSLog(@"foo");
}
And for more confusion, after read Apple iOS Documentation I get this stuff:
- (void)setContentOffset:(CGPoint)contentOffset animated:(BOOL)animated {
NSLog(@"bar");
}
First event are fired, but from Apple documentation are not. Why?!
But in the first case, although he was fired the UIScrollView loses their
scroll/drag'n' bounce behavior. I think it's because after overrride
setContentOffset I would need to call the parent method to keep the
default behavior of the UIScrollView. But I'm already exhausted from test
obsolete Xcode approaches.
Than why second code are not fired and how call parent overridden method?

why i can interchange field values inside a class using class reference but can't interchange the references themselves
why i can interchange field values inside a class using class reference
but can't interchange the references themselves
Here is the code of the class i have written
class Demo
{
int x,y;
Demo(int a,int b){x=a;y=b;}
public void swap(Demo ref) // interchanges field values of x and y
{
int temp;
temp=ref.x;
ref.x=ref.y;
ref.y=temp;
}
public void change(Demo ref1,Demo ref2) // supposed to interchange to
class variables of Demo class
{
Demo temp = ref1;
ref1 = ref2;
ref2 = temp;
}
}
swap method works fine i.e. interchange values of x and y.
Now, I have two questions here:
how the swap method is able to change the actual data passed to it? (I
have read that their is no pass by reference in Java.)
why change method does not interchange class references?

I made a web page where one have to login. I login, and it redirects me to
my homepage. On that page there is a heading that says "Welcome back, #my

gave. The problem is that the result of the query returns blank. What's
the problem?
home.php:
$query = mysql_query("SELECT name FROM user_info WHERE username='$user'")
or die(mysql_error());
$result = mysql_fetch_array($query);
if(!$result){echo mysql_error();}

WinPhone: How to add custom confirmation dialog in OnBackKeyPress
WinPhone: How to add custom confirmation dialog in OnBackKeyPress
I am going to implement custom confirmation dialog in OnBackKeyPress
method. It is easy to do with native message box:
protected override void OnBackKeyPress(CancelEventArgs e)
{
base.OnBackKeyPress(e);
MessageBoxResult result = MessageBox.Show("Text");
if(result==MessageBoxResult.OK)
{
e.Cancel = true;
}
}
It works, but I dislike limitation with two buttons so I am looking for
something else.
I have checked WPtoolkit:
private bool m_cansel = false;
protected override void OnBackKeyPress(CancelEventArgs e)
{
base.OnBackKeyPress(e);
if (!m_cansel)
{
e.Cancel = true;
m_cansel = true;
var messageBox = new CustomMessageBox
{
Title = "Title",
Message = "Message",
RightButtonContent = "aas",
IsLeftButtonEnabled = false,
};
messageBox.Dismissed += (sender, args) =>
{
};
messageBox.Show();
}
}
And Coding4Fun:
private bool m_cansel = false;
protected override void OnBackKeyPress(CancelEventArgs e)
{
base.OnBackKeyPress(e);
if (!m_cansel)
{
e.Cancel = true;
m_cansel = true;
var messageBox = new MessagePrompt
{
Title = "Title",
Message = "Message",
};
messageBox.Completed += (sender, args) =>
{
//throw new NotImplementedException();
};
messageBox.Show();
}
Both looks good, but don't work in OnBackKeyPress method (show and
immediately disappear without any my action).
Moreover, I've tried XNA:
private bool m_cansel = false;
protected override void OnBackKeyPress(CancelEventArgs e)
{
base.OnBackKeyPress(e);
if (!m_cansel)
{
e.Cancel = true;
m_cansel = true;

Windows.",
new List<string> {"Vista", "Seven"}, 0,

asyncResult =>

Guide.EndShowMessageBox(asyncResult);
}, null);
}
}
It works as I expected (has customs in OnBackKeyPress method), but I don't
sure that using XNA inside Silverlight app is good practice.
So, I am looking a way to use WPtoolkit or Coding4Fun windows inside
OnBackKeyPress method or any explanation about using XNA inside
Silverlight app (any recomendation or info about approval such kind app by
store).

Blink upon incoming call android
Blink upon incoming call android
I am developing an android app, where I want make the home screen blink
upon incoming call. I tried calling the below startblinking() method
within a activity and the screen blinks fine.
But, when I try to call the same method within the Ring state of a
phonelistener(inside a Service class), I get the following error, since
the service class doesnt have a window.
The method getWindow() is undefined for the type PhoneListener
..
private void startblinking()
{
Log.e("inside","blink MEthod");
timerforblinking.scheduleAtFixedRate(new TimerTask()
{
@Override
public void run()
{
runOnUiThread(new Runnable()
{
public void run()
{
time = (float) (time + 0.5);
if(time == 0.5 || time == 1.5 || time == 2.5 || time
== 3.5 || time == 4.5 || time == 5.5)
{
Log.e("time","OFF - time = "+time);
layoutParams.screenBrightness = (float) 30 / 255;

}
}
});
}

Is there a possible workaround to achieve the screen blinking upon
incoming calls.
Please help.Thanks!

Cannot publish table without primary keys
Cannot publish table without primary keys
I've used the following link Sqltraining to create a job that will keep
historical data of my database growth. However, since I have several
different instances of servers across locations, I will be using a
previously replicated database and add the table as per step #2 in the
link. However, I cannot publish the new article/ table because it does not
have primary key. I am confused as to which one should be the primary key.
Can anyone please help. Thanks.

HTML5 Responsive Web Design: Fixed Header Not Working
HTML5 Responsive Web Design: Fixed Header Not Working
I'm trying to create a basic HTML5 responsive web design where the header
is fixed. I am trying to keep my HTML and CSS code clean and follow best
practices. The header has a max width of 980 pixels but the blue header
background expands to fill the window (see the diagram).
Right now there's a few issues with my CSS (maybe my HTML) that are
causing the header to cover up the content below the header. The header's
blue background is also not expanding to fill the left of the window. I
also can't get the logo image to center vertically on the header. What I
am I missing? I've been playing around with this all night but I've been
unable to iron out these issues.
Fiddle: http://jsfiddle.net/DU3D6/
CSS

jdbc connection error: not associated with a managed connection
jdbc connection error: not associated with a managed connection
My application is trowing the following exception:
java.sql.SQLException: Connection is not associated with a managed
connection.org.jboss.resource.adapter.jdbc.jdk6.WrappedConnectionJDK6@4fe91321
This is happening in production I'm not able to get this problem in
development and for that I'm not able to solve it.
The root of the exception is code line dbConn.prepareStatement(sql);
From what I was able to find in the web, the cause for this can be:
1. Over jdbc connection, a jboss connection is wrapped but the wrapper
is empty. The original jdbc connection inside is no longer there.
2. JDBC Connection is already closed and trying to work with close
connection is the reason why I'm getting this exception
3. The transaction manger detects transaction that is taking to long
then the transaction timeout,
So if someone can point me what is the problem because I'm not able to get
this problem in mine development environment.
Also what logs can I add that will help me detect the problem in
production - I'm using Java, JBoss, Postgres
I'have enable connection close monitoringa, and also to add is that the
issue is not consistent

How do I pass on the search string from one class to another?
How do I pass on the search string from one class to another?
I have a search View which is defined as follows in a class basesearch.java:
protected EditText mSearchView;
(It refers to the basic textbox search view).
Now in class searchfragment.java, I have the following method:
private void runSearch(final String searchTerm) {
if(searchTerm.contains(mSearchView.getText().toString().toLowerCase()
+ " " + mSearchView.getText().toString().toLowerCase())){
AWebViewFragment.newInstanceForSearch(getFragmentManager(), null,
null);
}else {
SearchResultsFragment.newInstance(getFragmentManager(),
searchTerm);
}
}
Note: mSearchView.getText().toString().toLowerCase() is getting the typed
in search value. Now, I want to use this value
"mSearchView.getText().toString().toLowerCase()" and pass it on to another
class which is being called "AWebViewFragment" in the first if clause. I
am defining the AwebViewfragment as follwos:
public static String OUTPUT_ENVIRONMENT =
"https://mobile13.cp.com/msf1.0/fwd/answers/service/v1/?q="+mSearchView.getText().toString().toLowerCase()+"%20revenue&ui.theme=novadark&uuid=PADACT-002&userAgent=iphone";
However it throws an error at mSearchView,unless I set some dummy value
defining it. I want it to be able to get information from previous class
for the typed in search term. I wonder what I am doing wrong. I want the
url to display with the dynamically typed search term. Is it possible to
do the same somehow? Feel free to modify the code and walk me thru a new
change, I will try any suggestions for new code or improvements. Any help
greatly appreciated. Thanks! Justin Also, I am already using the bundles
in Awebviewfragment:
private static AWebViewFragment __newInstance(final AnswersWebViewFragment
fragment, final FragmentManager manager,
final String searchTerm, final String symbolType, int
containerViewId, final int inAnimation, final int
outAnimation, final int popInAnimation, final int
popOutAnimation) {
final Bundle bundle = new Bundle();
bundle.putString(SEARCH_TERM, searchTerm);
bundle.putString(AnswersWebViewFragment.SYMBOL_TYPE, symbolType);
bundle.putInt(AnswersWebViewFragment.CONTAINER_ID, containerViewId);
fragment.setArguments(bundle);
FragmentInfo fragmentInfo = new
FragmentInfo(TransactionMethods.ADD, containerViewId);
fragmentInfo.setAnimation(inAnimation, outAnimation);
fragmentInfo.setPopAnimation(popInAnimation, popOutAnimation);
fragmentInfo.setFragmentTag(TAG_A_FRAGMENT_WEBVIEW);
fragmentInfo.setActionBarTitle(Application.getAppResources().getString(R.string.nav_option_quotes));
FragmentStackManager.getInstance().transitionFragment(manager,
fragment, fragmentInfo);
return fragment;
}
And OUTPUT_ENVIRONMENT is defined outside the method for bundle, how do i
retrieve the search term passed on from the previous class? and oncreate I
am using :
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mSearchTerm = getArguments().getString(SEARCH_TERM);
}

How do I fix the answersWebviewfragment to retrieve the searchterm??
I have a search View which is defined as follows in a class basesearch.java:
protected EditText mSearchView;
(It refers to the basic textbox search view).
Now in class searchfragment.java, I have the following method:
private void runSearch(final String searchTerm) {
if(searchTerm.contains(mSearchView.getText().toString().toLowerCase()
+ " " + mSearchView.getText().toString().toLowerCase())){
AWebViewFragment.newInstanceForSearch(getFragmentManager(), null,
null);
}else {
SearchResultsFragment.newInstance(getFragmentManager(),
searchTerm);
}
}
Note: mSearchView.getText().toString().toLowerCase() is getting the typed
in search value. Now, I want to use this value
"mSearchView.getText().toString().toLowerCase()" and pass it on to another
class which is being called "AWebViewFragment" in the first if clause. I
am defining the AwebViewfragment as follwos:
public static String OUTPUT_ENVIRONMENT =
"https://mobile13.cp.com/msf1.0/fwd/answers/service/v1/?q="+mSearchView.getText().toString().toLowerCase()+"%20revenue&ui.theme=novadark&uuid=PADACT-002&userAgent=iphone";
However it throws an error at mSearchView,unless I set some dummy value
defining it. I want it to be able to get information from previous class
for the typed in search term. I wonder what I am doing wrong. I want the
url to display with the dynamically typed search term. Is it possible to
do the same somehow? Feel free to modify the code and walk me thru a new
change, I will try any suggestions for new code or improvements. Any help
greatly appreciated. Thanks! Justin Also, I am already using the bundles
in Awebviewfragment:
private static AWebViewFragment __newInstance(final AnswersWebViewFragment
fragment, final FragmentManager manager,
final String searchTerm, final String symbolType, int
containerViewId, final int inAnimation, final int
outAnimation, final int popInAnimation, final int
popOutAnimation) {
final Bundle bundle = new Bundle();
bundle.putString(SEARCH_TERM, searchTerm);
bundle.putString(AnswersWebViewFragment.SYMBOL_TYPE, symbolType);
bundle.putInt(AnswersWebViewFragment.CONTAINER_ID, containerViewId);
fragment.setArguments(bundle);
FragmentInfo fragmentInfo = new
FragmentInfo(TransactionMethods.ADD, containerViewId);
fragmentInfo.setAnimation(inAnimation, outAnimation);
fragmentInfo.setPopAnimation(popInAnimation, popOutAnimation);
fragmentInfo.setFragmentTag(TAG_A_FRAGMENT_WEBVIEW);
fragmentInfo.setActionBarTitle(Application.getAppResources().getString(R.string.nav_option_quotes));
FragmentStackManager.getInstance().transitionFragment(manager,
fragment, fragmentInfo);
return fragment;
}
And OUTPUT_ENVIRONMENT is defined outside the method for bundle, how do i
retrieve the search term passed on from the previous class? and oncreate I
am using :
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mSearchTerm = getArguments().getString(SEARCH_TERM);
}

fragment, fragmentInfo);
return fragment;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mSearchTerm = getArguments().getString(SEARCH_TERM);
}
