  • Javascript error after updating ASP.NET AJAX ControlToolkit

    - by empo
    I've just updated to the AJAX Control Toolkit 3.5, changed the ScriptManager to the ToolkitScriptManager in my master page and now the following javascript error occurs when an Edit button is clicked: "Object doesn't support this property or method" The line of code cuasing the error is: this._destroyTree(updatePanelElement); Any initial ideas before I post masses of code?

  • Undefined Behavior and Sequence Points Reloaded

    - by Nawaz
    Consider this topic a sequel of the following topic: Previous Installment Undefined Behavior and Sequence Points Let's revisit this funny and convoluted expression (the italicized phrases are taken from the above topic *smile* ): i += ++i; We say this invokes undefined-behavior. I presume that when say this, we implicitly assume that type of i is one of built-in types. So my question is: what if the type of i is a user-defined type? Say it's type is Index which is defined later in this post (see below). Would it still invoke undefined-behavior? If yes, why? Is it not equivalent to writing i.operator+=(i.operator ++()); or even syntactically simpler i.add(i.inc());? Or, do they too invoke undefined-behavior? If no, why not? After all, the object i gets modified twice between consecutive sequence points. Please recall the rule of thumb : an expression can modify an object's value only once between consecutive "sequence points. And if i += ++i is an expression, then it must invoke undefined-behavior. If so, then it's equivalents i.operator+=(i.operator ++()); and i.add(i.inc()); must also invoke undefined-behavior which seems to be untrue! (as far as I understand) Or, i += ++i is not an expression to begin with? If so, then what is it and what is the definition of expression? If it's an expression, and at the same time, it's behavior is also well-defined, then it implies that number of sequence points associated with an expression somehow depends on the type of operands involved in the expression. Am I correct (even partly)? By the way, how about this expression? a[++i] = i; //taken from the previous topic. but here type of `i` is Index. class Index { int state; public: Index(int s) : state(s) {} Index& operator++() { state++; return *this; } Index& operator+=(const Index & index) { state+= index.state; return *this; } operator int() { return state; } Index & add(const Index & index) { state += index.state; return *this; } Index & inc() { state++; return *this; } };

  • Add New Gist using the Github API

    - by Ben Shelock
    I'm making a small app in Adobe Air which I need to interact with the Github Gist API. However I'm kind of stuck. If you're not familiar with Adobe Air you can still help, the XMLHttpRequest javascript object can do cross domain requests, as there is no domain as such. So theres nothing Adobe Air specific here. Where I'm stuck is I think I need to authenticate myself then make the POST. I just don't understand it

  • GridLayout with single column

    - by Albinoswordfish
    Right now I'm trying to use a GridLayout with only a single column. However I'm having a problem where I don't want the object, in this case a JButton, to be stretched the entire width of the JPanel that it's on. Is there a way to decrease the width of the JButton so that it does not stretch the entire width of the JPanel. I've tried using setPreferredSize and setSize with no results. Is this just the way GridLayout works or is there something I'm missing?

  • Combining MEF and IoC container

    - by Einar Ingebrigtsen
    I primarily use NInject as my IoC container, and is very happy with it - don't want to change that. But some things I want to import using MEF. The thing is, I want the imports to created by the IoC container as the imports can have dependencies to things that I've registered in the NInject IoC. So, my question is: can I import the type of exports in some way, so I can hand it over to NInject for creation or is there an object factory of some kind that I can override in MEF?

    I got the public key from the certificate, keypair is a java.security.KeyPair object String public_key = keypair.getPublic().toString(); I want to send this to the via an http connection to a J2me application. I cannot find any documentation to convert the transmitted string to a Public key that can be used to encrypt Strings. I also want the J2me to verify signed strings from the server. I want to then send the encrypted strings back to the server.

  • iphone calls both if and else at the same time?

    - by David Schiefer
    Hi, I need to determine what file type a file is and then perform a certain action for it. this seems to work fine for some types, however all media types such as videos and sound files get mixed up. I determine the file type by doing this: BOOL matchedMP3 = ([[rowValue pathExtension] isEqualToString:@"mp3"]); if (matchedMP3 == YES) { NSLog(@"Matched MP3"); } I do this for various file types and just define an "else" for all the others. Here's the problem though. The iPhone calls them both. Here's what the log reveals: 2010-05-11 18:51:12.421 Test [5113:207] Matched MP3 2010-05-11 18:51:12.449 Test [5113:207] Matched ELSE I've never seen anything like this before. This is my "matchedMP3" function: BOOL matchedMP3 = ([[rowValue pathExtension] isEqualToString:@"mp3"]); if (matchedMP3 == YES) { NSLog(@"Matched MP3"); NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSFileManager *manager = [NSFileManager defaultManager]; self.directoryContent = [manager directoryContentsAtPath:documentsDirectory]; NSString *errorMessage = [documentsDirectory stringByAppendingString:@"/"]; NSString *urlAddress = [errorMessage stringByAppendingString:rowValue]; MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:urlAddress]]; moviePlayer.movieControlMode = MPMovieControlModeDefault; moviePlayer.backgroundColor = [UIColor blackColor]; [moviePlayer play]; } and here's the else statement: else { NSLog(@"Matched ELSE"); [[NSUserDefaults standardUserDefaults] setObject:rowValue forKey:@"rowValue"]; NSString*rowValue = [[NSUserDefaults standardUserDefaults] objectForKey:@"rowValue"]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSFileManager *manager = [NSFileManager defaultManager]; self.directoryContent = [manager directoryContentsAtPath:documentsDirectory]; NSString *errorMessage = [documentsDirectory stringByAppendingString:@"/"]; NSString *urlAddress = [errorMessage stringByAppendingString:rowValue]; webViewHeader.prompt = rowValue; [documentViewer setDelegate:self]; NSString *encodedString = [urlAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; //Create a URL object. NSURL *url = [NSURL URLWithString:encodedString]; //URL Requst Object NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; //Load the request in the UIWebView. [documentViewer loadRequest:requestObj]; [navigationController pushViewController:webView animated:YES]; } I can't see a reason why it wouldn't work. What happens is that both the webview and the MediaPlayer toggle their own player, so they overlap and play their sound/video a few secs apart from each other. Any help would be appreciated & thank for you taking the time to read through my code.

  • Winforms: calling entry form function from a different class

    - by samy
    I'm kinda new to programming and got a question on what is a good practice. I created a class that represents a ball and it has a function Jump() that use 2 timers and get the ball up and down. I know that in Winforms you got to call Invalidate() every time you want to repaint the screen, or part of it. I didn't find a good way to do that, so I reference the form in my class, and called Invalidate() inside my ball class every time I need to repaint to ball movement. (this works but I got a feeling that this is not a good practice) Here is the class I created: public class Ball { public Form1 parent;//----> here is the reference to the form public Rectangle ball; Size size; public Point p; Timer timerBallGoUp = new Timer(); Timer timerBallGDown = new Timer(); public int ballY; public Ball(Size _size, Point _p) { size = _size; p = _p; ball = new Rectangle(p, size); } public void Jump() { ballY = p.Y; timerBallGDown.Elapsed += ballGoDown; timerBallGDown.Interval = 50; timerBallGoUp.Elapsed += ballGoUp; timerBallGoUp.Interval = 50; timerBallGoUp.Start(); } private void ballGoUp(object obj,ElapsedEventArgs e) { p.Y++; ball.Location = new Point(ball.Location.X, p.Y); if (p.Y >= ballY + 50) { timerBallGoUp.Stop(); timerBallGDown.Start(); } parent.Invalidate(); // here i call parent.Invalidate() 1 } private void ballGoDown(object obj, ElapsedEventArgs e) { p.Y--; ball.Location = new Point(ball.Location.X, p.Y); if (p.Y <= ballY) { timerBallGDown.Stop(); timerBallGoUp.Start(); } parent.Invalidate(); // here i call parent.Invalidate() 2 } } I'm wondring if there is a better way to do that? (sorry for my english)

  • The difference between lists and sequences

    - by Peanut
    I'm trying to understand the difference between sequences and lists. In F# there is a clear distinction between the two. However in C# I have seen programmers refer to IEnumerable collections as a sequence. Is what makes IEnumerable a sequence the fact that it returns an object to iterate through the collection? Perhaps the real distinction is purely found in functional languages?

  • Save simple data in Magento's DB w/o Model

    - by Joseph Mastey
    I'm looking to save some data in the Magento database without hassling with creating a new EAV object (or even a DB table if I can avoid it). Is there any place that you all know about that Magento will let you store serialized data? If it matters, the data is a serialized set of SKUs that I need to retrieve. I know that I could create a new model, or possibly even create an attribute as a flag on each product, but those are both really overkill for my purposes. Thanks, Joe

  • Pyplot connect to timer event?

    - by Baron Yugovich
    The same way I now have plt.connect('button_press_event', self.on_click) I would like to have something like plt.connect('each_five_seconds_event', self.on_timer) How can I achieve this in a way that's most similar to what I've shown above? EDIT: I tried fig = plt.subplot2grid((num_cols, num_rows), (col, row), rowspan=rowspan, colspan=colspan) timer = fig.canvas.new_timer(interval=100, callbacks=[(self.on_click)]) timer.start() And got AttributeError: 'AxesSubplot' object has no attribute 'canvas'
