  • actionscript 3 addchild within child and fade

    - by steve
    Here is my current code: import flash.display.*; import fl.transitions.*; import flash.events.MouseEvent; stop(); var container:MovieClip = new MovieClip(); container.width = 450; container.height = 450; container.x = 450; container.y = 0; var closeBtn:close_btn = new close_btn(); closeBtn.x = 850; closeBtn.y = 15; var bagLink:MovieClip = new bag_link_mc(); bagLink.x = 900; bagLink.y = 0; menu_bag_button.addEventListener(MouseEvent.CLICK, bagClick); function bagClick(event:MouseEvent):void{ if(MovieClip(root).currentFrame == 850) { } else { MovieClip(root).addChild (bagLink); MovieClip(root).addChild (closeBtn); MovieClip(root).gotoAndPlay(806); } } closeBtn.addEventListener(MouseEvent.CLICK, closeBag); function closeBag (event:MouseEvent):void{ MovieClip(root).removeChild(bagLink); MovieClip(root).removeChild(closeBtn); MovieClip(root).gotoAndPlay(850); } I need the first mouse function (bagClick) to create the bagLink within the container movieclip variable. I tried change it to this, but it didn't work: else { MovieClip(root).addchild (container); MovieClip(root).container.addChild (bagLink); MovieClip(root).addChild (closeBtn); MovieClip(root).gotoAndPlay(806); } I'm also trying to make "container" or "bagLink" fade in when it loads but that doesn't work either. Any help is appreciated.

  • Access Internet From My Blackberry App

    - by Ankit
    Hi all, This is my first attemp to code a blackberry app so please bear with me. I am developing an app to make it easy to access certain information from certain websites using screenscrapping. Now I am done with the ui part of the application onto the internet access part. My question is how do i access internet from my app ? I see that blackberry offers http, wifi and some other forms to access the internet ... does my app need to be worried about what mode is being used ? or as far as my app is concerned theres a general api to access the net with the logic of connecting to the internet being handled by the device itself ..? any pointers with some sample code would be much appreciated. thank you, ankit

  • the scope of a pointer ???

    - by numerical25
    Ok, so I did find some questions that were almost similar but they actually confused me even more about pointers. http://stackoverflow.com/questions/2715198/c-pointer-objects-vs-non-pointer-objects-closed In the link above, they say that if you declare a pointer it is actually saved on the heap and not on the stack, regardless of where it was declared at. Is this true ?? Or am I misunderstanding ??? I thought that regardless of a pointer or non pointer, if its a global variable, it lives as long as the application. If its a local variable or declared within a loop or function, its life is only as long as the code within it.

  • Running and managing NSTimer in different NSThread/NSRunLoop

    - by mips
    I'm writing a Cocoa application, with a GUI designed in Interface Builder. I need to schedule background activity (at regular intervals) without blocking the UI, so I run it in a separate thread, like this: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { [self performSelectorInBackground:@selector(schedule) withObject:nil]; } - (void) schedule { NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; NSRunLoop* runLoop = [NSRunLoop currentRunLoop]; timer = [[NSTimer scheduledTimerWithTimeInterval:FEED_UPDATE_INTERVAL target:activityObj selector:@selector(run:) userInfo:nil repeats:YES] retain]; [runLoop run]; [pool release]; } I retain the timer, so I can easily invalidate and reschedule. Problem: I must also fire the run: method in response to GUI events, so it is synchronous (i.e. a "perform activity" button). Like this: [timer fire]; I could do this with performSelectorInBackground too, and of course it doesn't block the UI. But this synchronous firings run in another runloop! So I have no guarantee that they won't overlap. How can I queue all of my firings on the same runloop?

  • Suggestions for displaying code on webpages, MUST use <br> for newline

    - by bguiz
    Hi, I want to post code snippets online (wordpress.com blog) - and have its whitespace formatted nicely. See the answers suggested by this other SO question: Those would be OK, except that I like to copy code to clip board or clip entire pages using Evernote - and they use either the <pre> tag or <table> (or both) to format the code. So I end up with text whose newlines and white spaces ignored, e.g. string url = "<a href=\"" + someObj.getUrl() + "\" target=\"_blank\">"; // single line comments // second single line override protected void OnLoad(EventArgs e) { if(Attributes["class"]&nbsp;!= null) { //_year.CssClass = _month.CssClass = _day.CssClass = Attributes["class"]; } base.OnLoad(e); } Which I find rather annoying myself. I find that if the code was formatted using <br> tags, they copy/ clip porperly, e.g. string url = "<a href=\"" + someObj.getUrl() + "\" target=\"_blank\">"; // single line comments // second single line override protected void OnLoad(EventArgs e) { if(Attributes["class"]&nbsp;!= null) { //_year.CssClass = _month.CssClass = _day.CssClass = Attributes["class"]; } base.OnLoad(e); } I find this annoying myself, so I don't want to inflict it upon others when I post my own code. Please suggest methods of posting code snippets online that are able to do this. I would like to emphasise that syntax highlighting capability is secondary to correct white space markup. Thank you

  • Best way to learn iphone audio queue services, step by step tutorial

    - by optician
    Hi Everyone, I'm trying to learn how to handle audio at a fairly low level with audio queue services. I have been progrmaing in memory managed languages for quite a while, and have just completed the c programing tutorial by vtc (2007). This has left me comfortable with the understanding of pointers and memory allocation, but the apple documention still leaves me wanting for a simpler implenation and explaination. Maybe I need to learn objective c and cocoa better. I have heard that this book is good. Cocoa(R) Programming for Mac(R) OS X (3rd Edition) Could someone suggest a learning path that is going to help me get an better understanding of working with audio and an iphone. I want to be able to play mp3 files back and also alter the pitch of them as they are playing. I am prepared that I may have to temporarily convert the mp3 files into pcm files to do things like that to them. Thanks everyone.

  • Exposing a pointer in Boost.Python

    - by Goose Bumper
    I have this very simple C++ class: class Tree { public: Node *head; }; BOOST_PYTHON_MODULE(myModule) { class_<Tree>("Tree") .def_readwrite("head",&Tree::head) ; } I want to access the head variable from Python, but the message I see is: No to_python (by-value) converter found for C++ type: Node* From what I understand, this happens because Python is freaking out because it has no concept of pointers. How can I access the head variable from Python? I understand I should use encapsulation, but I'm currently stuck with needing a non-encapsulation solution.

  • Convert an exception into HTTP 404 response in the Application_Error

    - by Dmitriy Nagirnyak
    Hi, First of all, quickly what exactly I want to achieve: translate particular exception into the HTTP 404 so the ASP.NET can handle it further. I am handling exceptions in the ASP.NET (MVC2) this way: protected void Application_Error(object sender, EventArgs e) { var err = Server.GetLastError(); if (err == null) return; err = err.GetBaseException(); var noObject = err as ObjectNotFoundException; if (noObject != null) HandleObjectNotFound(); var handled = noObject != null; if (!handled) Logger.Fatal("Unhandled exception has occured in application.", err); } private void HandleObjectNotFound() { Server.ClearError(); Response.Clear(); // new HttpExcepton(404, "Not Found"); // Throw or not to throw? Response.StatusCode = 404; Response.StatusDescription = "Not Found"; Response.StatusDescription = "Not Found"; Response.Write("The whole HTML body explaining whata 404 is??"); } The problem is that I cannot configure default customErrors to work with it. When it is on then it never redirects to the page specified in customErrors: <error statusCode="404" redirect="404.html"/>. I also tried to raise new HttpExcepton(404, "Not Found") from the handler but then the response code is 200 which I don't understand why. So the questions are: What is the proper way of translating AnException into HTTP 404 response? How does customErrors section work when handling exceptions in Application_Error? Why throwing HttpException(404) renders (blank) page with success (200) status? Thanks, Dmitriy.

  • Dynamically loaded control - how can I access a value in Page_Init

    - by Sam
    I am loading a LinkButton dynamically when a user clicks on another LinkButton. I am attaching an event handler to it. When the user clicks on the dynamically loaded LinkButton, the event does not fire. From what I've been reading, I understand this is because when the page posts back the dynamically loaded control no longer exists. It looks like I'm supposed to make sure this control is recreated in Page_Init. The dynamically created LinkButton is dependedent on a value (Product ID). I need someway to access this value so I can properly create the control. ViewState is not accessible and I'm concerned if I use Session it could time out and then that wouldn't help. Any ideas? Also, I hardcoded a Product ID value just for testing, and that still did not cause the event to fire. Is there something else I need to do? protected void Page_Init(object sender, EventArgs e) { SetTabText(1, 1); } SetTabText calls SetActionLinks which creates the LinkButton: protected Panel SetActionLinks(int prodID, int tabID) { ... LinkButton lnkBtn = new LinkButton(); lnkBtn.ID = "lnkBtn" + rand.Next().ToString(); lnkBtn.CommandName = "action"; lnkBtn.Command += new CommandEventHandler(this.lnkAction_Command); panel.Controls.Add(lnkBtn); ... } void lnkAction_Command(object sender, CommandEventArgs e) { LinkButton btn = (LinkButton)sender; switch (btn.CommandArgument) { AddCart(); } }

  • UIImageWriteToSavedPhotosAlbum with malloc_error

    - by lbalves
    I have an NIB file with a button. When I click this button, the setWallpaper: selector is called. Everything works as expected (the image is saved), excepte by the error thrown by malloc. malloc: *** error for object 0x184d000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I've set a breakpoint at malloc_error_break, but I don't understand anything from the debugger. I couldn't even find the object 0x184d000. Does anyone know why is this happening? I had also tried to retain the UIImage before sending it to UIImageWriteToSavedPhotosAlbum, but without success. My code is below: - (IBAction)setWallpaper:(id)sender { UIImage *image = [UIImage imageNamed:@"wallpaper_01.png"]; UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil); } - (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Galo!!!",@"Saved image message: title") message:NSLocalizedString(@"Now, check your \"saved photos\" group at \"photos\" app in your iPhone and select the actions menu > set as wallpaper.",@"Saved image message") delegate:nil cancelButtonTitle:NSLocalizedString(@"OK",@"OK Button") otherButtonTitles:nil]; [alertView show]; [alertView release]; }

  • How to keep track of TextPointer in WPF RichTextBox?

    - by Alan Spark
    I'm trying to get my head around the TextPointer class in a WPF RichTextBox. I would like to be able to keep track of them so that I can associate information with areas in the text. I am currently working with a very simple example to try and figure out what is going on. In the PreviewKeyDown event I am storing the caret position and then in the PreviewKeyUp event I am creating a TextRange based on the before and after caret positions. Here is a code sample that illustrates what I am trying to do: // The caret position before typing private TextPointer caretBefore = null; private void rtbTest_PreviewKeyDown(object sender, KeyEventArgs e) { // Store caret position caretBefore = rtbTest.CaretPosition; } private void rtbTest_PreviewKeyUp(object sender, KeyEventArgs e) { // Get text between before and after caret positions TextRange tr = new TextRange(caretBefore, rtbTest.CaretPosition); MessageBox.Show(tr.Text); } The problem is that the text that I get is blank. For example, if I type the character 'a' then I would expect to find the text "a" in the TextRange. Does anyone know what is going wrong? It could be something very simple but I've spent an afternoon getting nowhere. I am trying to embrace the new WPF technology but find that the RichTextBox in particular is so complicated that it makes even doing simple things like this difficult. If anyone has any links that do a good job of explaining the TextPointer, I would appreciate it if you can let me know.

  • Compile time Meta-programming, with string literals.

    - by Hassan Syed
    I'm writing some code which could really do with some simple compile time metaprogramming. It is common practise to use empty-struct tags as compile time symbols. I need to decorate the tags with some run-time config elements. static variables seem the only way to go (to enable meta-programming), however static variables require global declarations. to side step this Scott Myers suggestion (from the third edition of Effective C++), about sequencing the initialization of static variables by declaring them inside a function instead of as class variables, came to mind. So I came up with the following code, my hypothesis is that it will let me have a compile-time symbols with string literals use-able at runtime. I'm not missing anything I hope. template<class Instance> class TheBestThing { public: void set_name(const char * name_in) { get_name() = std::string(name_in); } void set_fs_location(const char * fs_location_in) { get_fs_location() = std::string(fs_location_in); } std::string & get_fs_location() { static std::string fs_location; return fs_location; } std::string & get_name() { static std::string name; return name; } }; struct tag {}; int main() { TheBestThing<tag> x; x.set_name("xyz"); x.set_fs_location("/etc/lala"); ImportantObject<x> SinceSlicedBread; }

  • Storing callbacks in a dictionary (Objective C for the iPhone)

    - by Casebash
    I am trying to store callbacks in a dictionary. I can't use blocks as the iPhone doesn't support this (unless you use plblocks). I tried using functions, but apparently NSMutableDictionary doesn't allow these pointers (wants an id) I tried using class methods, but I couldn't find a way to obtain a pointer to these I could try using functions with the c++ stl hashmap (if it is supported in Objective C++), but apparently this can slow compilation times. I could try storing both a class and a selector, but that seems rather messy. What would be the best way to do this?

  • ASP.NET MVC Get a list of users with particular profile properties

    - by Sam Huggill
    Hi, I'm using ASP.NET MVC 1 and I have added a custom Profile class using the WebProfile Builder VS add-in (found here: http://code.msdn.microsoft.com/WebProfileBuilder/Release/ProjectReleases.aspx?ReleaseId=980). On one of my forms I want a drop-down list of all users who share a specific profile value in common. I can see that I can get a list of all users using: Membership.GetAllUsers() However I cannot see how to get all users who have a specific profile value, which in my case is CellId. Am I approaching this in the right way? I have used membership roles to define which users are administrators etc, but profiles seems like the right place to group users. Any pointers both in specifics of how to access the user list but also comments on whether am I pursuing the right avenue here would be greatly appreciated. Many thanks, Sam

  • iPhone Keyboard hiding fields in UIWebView

    - by Pete
    Hi, I am a beginner at iPhone development and am hoping someone can help me with my question. I have a UIWebView displaying a web page. If the user taps inside a textbox on the web page then the keyboard pops up. This is great, but it hides the field that the user tapped on. I have looked around and found code samples to deal with this, but none that specifically deal with the UIWebView. I have implemented UIKeyboardDidShowNotification and UIKeyboardDidHideNotification but am not sure how to resize the UIWebView properly. I have tried putting the UIWebView in a UIScrollView but not had any success with that. The code below seems to adjust the UIWebView but won't let it scroll to the field. -(void) keyboardDidShow: (NSNotification *)notif{ if (keyboardShown) return; NSLog(@"Keyboard Show"); NSDictionary *info = [notif userInfo]; NSValue *aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; CGRect viewFrame = webBrowser.frame; viewFrame.size.height -= keyboardSize.height; webBrowser.frame = viewFrame; keyboardShown = YES; } -(void) keyboardDidHide: (NSNotification *)notif{ NSLog(@"Keyboard hide"); keyboardShown = NO; } Hopefully someone can help me or point me in the right direction. Thanks! Pete

  • How to find (in javascript) the current "scroll" offset in mobile safari / iphone

    - by mintywalker
    I'd like to know the x/y offset of the how far the user has "scrolled" within the viewport in mobile safari on the iphone. Put another way, if I (through javascript) reloaded the current page, I'd like to find the values I'd need to pass into window.scrollTo(...) in order to reposition the document/viewport as it is currently. window.pageXOffset always reports 0 jquery's $('body').scrollTop() always reports 0 events have a pageX, but this won't account for the scrolling of the page that happens after you release your finger if your gesture was to "flick" the page up/down. Namely, it'll give me a point when the finger leaves the screen, but that doesn't always match where the page will be after it's finished scrolling. Any pointers?

  • Retrieving well formed HTML using Jericho HTML parser in Java

    - by Raj
    Hello, I've looked at jTidy for converting a snipped of malformed/real-world HTML into well-formed HTML/XHTML. However, there's a bug in the latest version due to which I'm not able to use it. I'm looking at Jericho since it has a lot of positive reviews around the net. However, its not immediately obvious to me how one would go about implementing a method like: public String getValidHTML(String messedUpHTML) For instance, if it was passed <div>bar, it would return <div>bar</div> Any pointers would be helpful. Thanks in advance!

  • CALayer won't display

    - by Paul from Boston
    I'm trying to learn how to use CALayers for a project and am having trouble getting sublayers to display. I created a vanilla View-based iPhone app in XCode for these tests. The only real code is in the ViewController which sets up the layers and their delegates. There is a delegate, DelegateMainView, for the viewController's view layer and a second different one, DelegateStripeLayer, for an additional layer. The ViewController code is all in awakeFromNib, - (void)awakeFromNib { DelegateMainView *oknDelegate = [[DelegateMainView alloc] init]; self.view.layer.delegate = oknDelegate; CALayer *newLayer = [CALayer layer]; DelegateStripeLayer *sldDelegate = [[DelegateStripeLayer alloc] init]; newLayer.delegate = sldDelegate; [self.view.layer addSublayer:newLayer]; [newLayer setNeedsDisplay]; [self.view.layer setNeedsDisplay]; } The two different delegates are simply wrappers for the CALayer delegate method, drawLayer:inContext:, i.e., - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)context { CGRect bounds = CGContextGetClipBoundingBox(context); ... do some stuff here ... CGContextStrokePath(context); } each a bit different. The layer, view.layer, is drawn properly but newLayer is never drawn. If I put breakpoints in the two delegates, the program stops in DelegateMainView but never reaches DelegateStripeLayer. What am I missing here? Thanks.

  • how many fps can iPhone's UIGetScreenImage() actually do?

    - by M Katz
    Now that Apple is officially allowing UIGetScreenImage() to be used in iPhone apps, I've seen a number of blogs saying that this "opens the floodgates" for video capture on iPhones, including older models. But I've also seen blogs that say the fastest frame rate they can get with UIGetScreenImage() is like 6 FPS. Can anyone share specific frame-rate results you've gotten with UIGetScreenImage() (or other approved APIs)? Does restricting the area of the screen captured improve frame rate significantly? Also, for the wishful thinking segment of today's program, does anyone have pointers to code/library that uses UIGetScreenImage() to capture video? For instance, I'd like an API something like Capture( int fps, Rect bounds, int durationMs ) that would turn on the camera and for the given duration record a sequence of .png files at the given frame rate, copying from the given screen rect.

  • GridView doesn't remember state between postbacks

    - by Ryan
    Hi, I have a simple ASP page with databound grid (bound to an object source). The grid is within the page of a wizard and has a 'select' checkbox for each row. In one stage of the wizard, I bind the GridView: protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e) { ... // Bind and display matches GridViewMatches.EnableViewState = true; GridViewMatches.DataSource = getEmailRecipients(); GridViewMatches.DataBind(); And when the finish button is clicked, I iterate through the rows and check what's selected: protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e) { // Set the selected values, depending on the checkboxes on the grid. foreach (GridViewRow gr in GridViewMatches.Rows) { Int32 personID = Convert.ToInt32(gr.Cells[0].Text); CheckBox selected = (CheckBox) gr.Cells[1].FindControl("CheckBoxSelectedToSend"); But at this stage GridViewMatches.Rows.Count = 0! I don't re-bind the grid, I shouldn't need to, right? I expect the view-state to maintain the state. (Also, if I do rebind the grid, my selection checkboxes will be cleared) NB: This page also dynamically adds user controls in OnInit method. I have heard that it might mess with the view state, but as far as I can tell, I am doing it correctly and the viewstate for those added controls seems to work (values are persisted between postbacks) Thanks a lot in advance for any help! Ryan UPDATE: Could this be to do with the fact I am setting the datasource programatically? I wondered if the asp engine was databinding the grid during the page lifecycle to a datasource that was not yet defined. (In a test page, the GridView is 'automatically' databound'. I don't want the grid to re-bound I just want the values from the viewstate from the previous post! Also, I have this in the asp header: ViewStateEncryptionMode="Never" - this was to resolve an occasional 'Invalid Viewstate Validation MAC' message Thanks again Ryan

  • Java interface to Windows communications? (OLE, OPC, DDE)

    - by Jared
    I need to integrate an off-the-shelf Windows application with a Java application. At a few key points, I need the Windows application to send an "event" and some data to the Java application. The Windows application anticipated this need, and can be configured to "Poke a DDE Item", "Set an OLE Auto-Property" or "Write an OPC Item". I'm already using JACOB to call COM methods and set COM properties on a COM object. However, I'm guessing that's pretty unrelated to these "event" notification capabilities. Anyone have any experience calling FROM a Windows application to a "DDE Item", "OLE Auto-Property" or "OPC Item" that's actually in a JVM? Any pointers, advice, etc, would be appreciated.
