  • facebook iframe stream.Publish cannot close dialog or skip

    - by fooyee
    am pulling my hair over this :( spent 10 hrs but nothing came out I read this thread http://forum.developers.facebook.com/viewtopic.php?pid=198128 but it didn't help much. I'm running a local dev App Engine server ( localhost:8080 ) iframe app so I have a couple of problems. 1) on safari 4.0.4, the publish story dialog comes up nicely with all images/data/action_links. upon posting a story (or skipping), the dialog goes blank and wouldn't close. 2) I tested the same code on firefox 3.5.8, the dialog comes up with all images/data/action_links, but then the whole thing freezes. Clicking anywhere on the dialog doesn't help at all. If i'm patient enough and click "publish", I have to wait for abt 10 seconds before the dialog says "story is published". then it freezes. (clicking on skip doesn't make a difference). btw, there is no "button clicking effect" : ie: the buttons don't look like they "sink down" upon clicking. I checked the firefox memory using the command "top" on the terminal, it all seems okay, no spike in CPU processes ( i could open other firefox tabs and work on them) My futile attempts at solving the problems... 1) so i thought, hmm could this be because of local dev (localhost) problem? I uploaded the code to the production server, the same thing happens. 2) I tried an older firefox (3.1) and the same problem persisted ( the freezing ) 3) I noticed that i kind of used 2 different FB features ( Connect and XFBML). The Connect Feature I used in the PostStory function. The XFBML feature I used before the tag. So I thought, hmm ... I tried replacing the FB_RequireFeatures["Connect"] feature with FB_RequireFeatures["XFBML"]. nothing changed. I still can't close the story dialog. 4) Is there a possibility that I didn't connect to xd_receiver.htm properly? my xd_receiver.htm is stored in my folder /media/fbconnect in my app.yaml handler: - url: /fbconnect static_dir: media/fbconnect so i thought a connection has to be established with xd_receiver.htm. any way I can test that? here're all the codes: <script type="text/javascript"> //post story function function PostStory() { //init facebook FB_RequireFeatures(["Connect"], function() { FB.Facebook.init('my_app_key', "/fbconnect/xd_receiver.htm"); FB.ensureInit(function() { var message = 'the message'; var attachment = { 'name': 'a simple app to send gifts', 'href': 'http://apps.facebook.com/my_app_name', 'caption': '{*actor*} sent u something', 'description': 'some description', "media": [{ "type": "image", "src": "http://bit.ly/105QYr", "href": "http://bit.ly/105QYr"}] }; //action links can only be seen AFTER the feed is published var action_links = [{ 'text': 'Send him/her a gift back!', 'href': 'http://somelink.com'}]; FB.Connect.streamPublish(message, attachment, action_links, null, "Share the gift with your friends", callback, false, null); }); }); function callback(post_id, exception) { //alert('Wall Post Complete'); } } </script> just before the end of the /body tag, i have this: <script type="text/javascript"> function callFBInit() { FB_RequireFeatures( ["XFBML"], function(){ FB.Facebook.init("my_app_key", "/fbconnect/xd_receiver.htm"); } ); } callFBInit(); btw, my xd_receiver.htm contains: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns=? http://www.w3.org/1999/xhtml? > <head> <title>cross-domain receiver page</title> </head> <body> <script src=?http://static.ak.facebook.com/js/api_lib/v0.4/xdcommreceiver.debug.js? type=? text/javascript? ></script> </body> </html> hope you guys can help out. thx

  • How to write a test for accounts controller for forms authenticate

    - by Anil Ali
    Trying to figure out how to adequately test my accounts controller. I am having problem testing the successful logon scenario. Issue 1) Am I missing any other tests.(I am testing the model validation attributes separately) Issue 2) Put_ReturnsOverviewRedirectToRouteResultIfLogonSuccessAndNoReturnUrlGiven() and Put_ReturnsRedirectResultIfLogonSuccessAndReturnUrlGiven() test are not passing. I have narrowed it down to the line where i am calling _membership.validateuser(). Even though during my mock setup of the service i am stating that i want to return true whenever validateuser is called, the method call returns false. Here is what I have gotten so far AccountController.cs [HandleError] public class AccountController : Controller { private IMembershipService _membershipService; public AccountController() : this(null) { } public AccountController(IMembershipService membershipService) { _membershipService = membershipService ?? new AccountMembershipService(); } [HttpGet] public ActionResult LogOn() { return View(); } [HttpPost] public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (_membershipService.ValidateUser(model.UserName,model.Password)) { if (!String.IsNullOrEmpty(returnUrl)) { return Redirect(returnUrl); } return RedirectToAction("Index", "Overview"); } ModelState.AddModelError("*", "The user name or password provided is incorrect."); } return View(model); } } AccountServices.cs public interface IMembershipService { bool ValidateUser(string userName, string password); } public class AccountMembershipService : IMembershipService { public bool ValidateUser(string userName, string password) { throw new System.NotImplementedException(); } } AccountControllerFacts.cs public class AccountControllerFacts { public static AccountController GetAccountControllerForLogonSuccess() { var membershipServiceStub = MockRepository.GenerateStub<IMembershipService>(); var controller = new AccountController(membershipServiceStub); membershipServiceStub .Stub(x => x.ValidateUser("someuser", "somepass")) .Return(true); return controller; } public static AccountController GetAccountControllerForLogonFailure() { var membershipServiceStub = MockRepository.GenerateStub<IMembershipService>(); var controller = new AccountController(membershipServiceStub); membershipServiceStub .Stub(x => x.ValidateUser("someuser", "somepass")) .Return(false); return controller; } public class LogOn { [Fact] public void Get_ReturnsViewResultWithDefaultViewName() { // Arrange var controller = GetAccountControllerForLogonSuccess(); // Act var result = controller.LogOn(); // Assert Assert.IsType<ViewResult>(result); Assert.Empty(((ViewResult)result).ViewName); } [Fact] public void Put_ReturnsOverviewRedirectToRouteResultIfLogonSuccessAndNoReturnUrlGiven() { // Arrange var controller = GetAccountControllerForLogonSuccess(); var user = new LogOnModel(); // Act var result = controller.LogOn(user, null); var redirectresult = (RedirectToRouteResult) result; // Assert Assert.IsType<RedirectToRouteResult>(result); Assert.Equal("Overview", redirectresult.RouteValues["controller"]); Assert.Equal("Index", redirectresult.RouteValues["action"]); } [Fact] public void Put_ReturnsRedirectResultIfLogonSuccessAndReturnUrlGiven() { // Arrange var controller = GetAccountControllerForLogonSuccess(); var user = new LogOnModel(); // Act var result = controller.LogOn(user, "someurl"); var redirectResult = (RedirectResult) result; // Assert Assert.IsType<RedirectResult>(result); Assert.Equal("someurl", redirectResult.Url); } [Fact] public void Put_ReturnsViewIfInvalidModelState() { // Arrange var controller = GetAccountControllerForLogonFailure(); var user = new LogOnModel(); controller.ModelState.AddModelError("*","Invalid model state."); // Act var result = controller.LogOn(user, "someurl"); var viewResult = (ViewResult) result; // Assert Assert.IsType<ViewResult>(result); Assert.Empty(viewResult.ViewName); Assert.Same(user,viewResult.ViewData.Model); } [Fact] public void Put_ReturnsViewIfLogonFailed() { // Arrange var controller = GetAccountControllerForLogonFailure(); var user = new LogOnModel(); // Act var result = controller.LogOn(user, "someurl"); var viewResult = (ViewResult) result; // Assert Assert.IsType<ViewResult>(result); Assert.Empty(viewResult.ViewName); Assert.Same(user,viewResult.ViewData.Model); Assert.Equal(false,viewResult.ViewData.ModelState.IsValid); } } }

  • Write a signal handler to catch SIGSEGV

    - by Adi
    Hi all, I want to write a signal handler to catch SIGSEGV. First , I would protect a block of memory for read or writes using char *buffer; char *p; char a; int pagesize = 4096; " mprotect(buffer,pagesize,PROT_NONE) " What this will do is , it will protect the memory starting from buffer till pagesize for any reads or writes. Second , I will try to read the memory by doing something like p = buffer; a = *p This will generate a SIGSEGV and i have initialized a handler for this. The handler will be called . So far so good. Now the problem I am facing is , once the handler is called, I want to change the access write of the memory by doing mprotect(buffer, pagesize,PROT_READ); and continue my normal functioning of the code. I do not want to exit the function. On future writes to the same memory, I want again catch the signal and modify the write rights and then take account of that event. Here is the code I am trying : #include <signal.h> #include <stdio.h> #include <malloc.h> #include <stdlib.h> #include <errno.h> #include <sys/mman.h> #define handle_error(msg) \ do { perror(msg); exit(EXIT_FAILURE); } while (0) char *buffer; int flag=0; static void handler(int sig, siginfo_t *si, void *unused) { printf("Got SIGSEGV at address: 0x%lx\n",(long) si->si_addr); printf("Implements the handler only\n"); flag=1; //exit(EXIT_FAILURE); } int main(int argc, char *argv[]) { char *p; char a; int pagesize; struct sigaction sa; sa.sa_flags = SA_SIGINFO; sigemptyset(&sa.sa_mask); sa.sa_sigaction = handler; if (sigaction(SIGSEGV, &sa, NULL) == -1) handle_error("sigaction"); pagesize=4096; /* Allocate a buffer aligned on a page boundary; initial protection is PROT_READ | PROT_WRITE */ buffer = memalign(pagesize, 4 * pagesize); if (buffer == NULL) handle_error("memalign"); printf("Start of region: 0x%lx\n", (long) buffer); printf("Start of region: 0x%lx\n", (long) buffer+pagesize); printf("Start of region: 0x%lx\n", (long) buffer+2*pagesize); printf("Start of region: 0x%lx\n", (long) buffer+3*pagesize); //if (mprotect(buffer + pagesize * 0, pagesize,PROT_NONE) == -1) if (mprotect(buffer + pagesize * 0, pagesize,PROT_NONE) == -1) handle_error("mprotect"); //for (p = buffer ; ; ) if(flag==0) { p = buffer+pagesize/2; printf("It comes here before reading memory\n"); a = *p; //trying to read the memory printf("It comes here after reading memory\n"); } else { if (mprotect(buffer + pagesize * 0, pagesize,PROT_READ) == -1) handle_error("mprotect"); a = *p; printf("Now i can read the memory\n"); } /* for (p = buffer;p<=buffer+4*pagesize ;p++ ) { //a = *(p); *(p) = 'a'; printf("Writing at address %p\n",p); }*/ printf("Loop completed\n"); /* Should never happen */ exit(EXIT_SUCCESS); } The problem I am facing with this is ,only the signal handler is running and I am not able to return to the main function after catching the signal.. Any help in this will be greatly appreciated. Thanks in advance Aditya

  • Passing an array argument from Excel VBA to a WCF service

    - by PrgTrdr
    I'm trying to pass an array as an argument to my WCF service. To test this using Damian's sample code, I modified GetData it to try to pass an array of ints instead of a single int as an argument: using System; using System.ServiceModel; namespace WcfService1 { [ServiceContract] public interface IService1 { [OperationContract] string GetData(int[] value); [OperationContract] object[] GetSomeObjects(); } } using System; namespace WcfService1 { public class Service1 : IService1 { public string GetData(int[] value) { return string.Format("You entered: {0}", value[0]); } public object[] GetSomeObjects() { return new object[] { "String", 123, 44.55, DateTime.Now }; } } } Excel VBA code: Dim addr As String addr = "service:mexAddress=""net.tcp://localhost:7891/Test/WcfService1/Service1/Mex""," addr = addr + "address=""net.tcp://localhost:7891/Test/WcfService1/Service1/""," addr = addr + "contract=""IService1"", contractNamespace=""http://tempuri.org/""," addr = addr + "binding=""NetTcpBinding_IService1"", bindingNamespace=""http://tempuri.org/""" Dim service1 As Object Set service1 = GetObject(addr) Dim Sectors( 0 to 2 ) as Integer Sectors(0) = 10 MsgBox service1.GetData(Sectors) This code works fine with the WCF Test Client, but when I try to use it from Excel, I have this problem. When Excel gets to the service1.GetData call, it reports the following error: Run-time error '-2147467261 (80004003)' Automation error Invalid Pointer It looks like there is some incompatibility between the interface specification and the VBA call. Have you ever tried to pass an array from VBA into WCF? Am I doing something wrong or is this not supported using the Service moniker?

  • Is it possible to specify a generic constraint for a type parameter to be convertible FROM another t

  • Get information about AutocompleteTextView from resulting AutoCompleteTextView$DropDownListView

    - by Stev_k
    I'm using 3 AutocompleteTextViews to suggest entries from a database. I subclassed AutocompleteTextView to handle setting the default text to null when clicked and setting back to the default instructions if moved away and nothing is entered. I was using a SimpleCursorAdapter to bind to the view, but I discovered that there was no way I could get the id of the AutocompleteTextView from an OnItemClickListener, which I needed to put additional information from the selected row in a variable depending on which AutocompleteTextView it was from. All I could access was the AutoCompleteTextView$DropDownListView, which is an undocumented inner class that appears to offer no real functionality. Neither was there a way to go up the view hierarchy to get the original AutocompleteTextView. So I subclassed SimpleCursorAdapter and added an int to the constructor to identify which AutocompleteTextView the adapter was from, and I was able to access this from the view passed into OnItemClick(). So, although my solution works fine, I wonder if it is possible to get the id of an AutocompleteTextView from its DropDownListView? I am also using another database query which gets the id from the OnItemClick and then looks up the data for that item, because I couldn't find a way of converting more than one column to a string. Should I be using CursorAdapter for this, to save initiating another query? Oh, and another thing, do I need a database cursor initially (all_cursor) when all I'm doing is filtering on it to get a new cursor? Seems like overkill. Activity .... dbse.openDataBase(); Cursor all_Cursor = dbse.autocomplete_query(); startManagingCursor(all_Cursor); String[] from_all = new String[]{DbAdapter.KEY_NAME}; int[] to_all = new int[] {android.R.id.text1}; from_adapt = new AutocompleteAdapter(FROM_DBADAPTER, this,android.R.layout.simple_dropdown_item_1line, all_Cursor, from_all, to_all); from_adapt.setStringConversionColumn(1); from_adapt.setFilterQueryProvider(this); to_adapt = new AutocompleteAdapter(TO_DBADAPTER, this,android.R.layout.simple_dropdown_item_1line, all_Cursor, from_all, to_all); to_adapt.setStringConversionColumn(1); to_adapt.setFilterQueryProvider(this); from_auto_complete = (Autocomplete) findViewById(R.id.entry_from); from_auto_complete.setAdapter(from_adapt); from_auto_complete.setOnItemClickListener(this); to_auto_complete = (Autocomplete) findViewById(R.id.entry_to); to_auto_complete.setAdapter(to_adapt); to_auto_complete.setOnItemClickListener(this); public void onItemClick (AdapterView<?> parent, View view, int position, long id) { Cursor selected_row_cursor = dbse.data_from_id(id); selected_row_cursor.moveToFirst(); String lat = selected_row_cursor.getString(1); String lon = selected_row_cursor.getString(2); int source = ((AutocompleteAdapter) parent.getAdapter()).getSource(); Autocomplete class: public class Autocomplete extends AutoCompleteTextView implements OnTouchListener,OnFocusChangeListener{ String textcontent; Context mycontext = null; int viewid = this.getId(); public Autocomplete(Context context, AttributeSet attrs) { super(context, attrs); textcontent = this.getText().toString(); mycontext = context; this.setOnFocusChangeListener(this); this.setOnTouchListener(this); } public boolean onTouch(View v, MotionEvent event) { if (textcontent.equals(mycontext.getString(R.string.from_textbox)) | textcontent.equals(mycontext.getString(R.string.to_textbox)) | textcontent.equals(mycontext.getString(R.string.via_textbox))) { this.setText(""); } return false; } public void onFocusChange(View v, boolean hasFocus) { if (hasFocus == false) { int a = this.getText().length(); if (a == 0){ if (viewid == R.id.entry_from) {this.setText(R.string.from_textbox);} if (viewid == R.id.entry_to) {this.setText(R.string.to_textbox);} if (viewid == R.id.entry_via) {this.setText(R.string.via_textbox);} } } } } Adapter: public class AutocompleteAdapter extends SimpleCursorAdapter { int source; public AutocompleteAdapter(int query_source, Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); source = query_source; } public int getSource() { return source; } } sorry that's a lot of code!

Here is what I'm trying to do: public class ShowToolbarBHO : BandObjectLib.IObjectWithSite { IWebBrowser2 webBrowser = null; public void SetSite (Object site) { ....... if (site != null) { ...... webBrowser = (IWebBrowser2)site; ...... } } } Also, I p/invoke the following COM methods: [Guid("0000010D-0000-0000-C000-000000000046")] [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] [ComImportAttribute()] public interface IViewObject { void Draw([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, [In] IntPtr ptd, IntPtr hdcTargetDev, IntPtr hdcDraw, [MarshalAs(UnmanagedType.LPStruct)] ref COMRECT lprcBounds, [In] IntPtr lprcWBounds, IntPtr pfnContinue, int dwContinue); int GetColorSet([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, [In] IntPtr ptd, IntPtr hicTargetDev, [Out] IntPtr ppColorSet); int Freeze([MarshalAs(UnmanagedType.U4)] int dwDrawAspect, int lindex, IntPtr pvAspect, out IntPtr pdwFreeze); int Unfreeze([MarshalAs(UnmanagedType.U4)] int dwFreeze); int SetAdvise([MarshalAs(UnmanagedType.U4)] int aspects, [MarshalAs(UnmanagedType.U4)] int advf, [MarshalAs(UnmanagedType.Interface)] IAdviseSink pAdvSink); void GetAdvise([MarshalAs(UnmanagedType.LPArray)] out int[] paspects, [MarshalAs(UnmanagedType.LPArray)] out int[] advf, [MarshalAs(UnmanagedType.LPArray)] out IAdviseSink[] pAdvSink); } [StructLayoutAttribute(LayoutKind.Sequential)] public class COMRECT { public int left; public int top; public int right; public int bottom; public COMRECT() { } public COMRECT(int left, int top, int right, int bottom) { this.left = left; this.top = top; this.right = right; this.bottom = bottom; } } [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] [ComVisibleAttribute(true)] [GuidAttribute("0000010F-0000-0000-C000-000000000046")] [ComImportAttribute()] public interface IAdviseSink { void OnDataChange([In]IntPtr pFormatetc, [In]IntPtr pStgmed); void OnViewChange([MarshalAs(UnmanagedType.U4)] int dwAspect, [MarshalAs(UnmanagedType.I4)] int lindex); void OnRename([MarshalAs(UnmanagedType.Interface)] object pmk); void OnSave(); void OnClose(); } Now When I take the snapshot: I make a call CaptureWebScreenImage((IHTMLDocument2) webBrowser.document); public static Image CaptureWebScreenImage(IHTMLDocument2 myDoc) { int heightsize = (int)getDocumentAttribute(myDoc, "scrollHeight"); int widthsize = (int)getDocumentAttribute(myDoc, "scrollWidth"); Bitmap finalImage = new Bitmap(widthsize, heightsize); Graphics gFinal = Graphics.FromImage(finalImage); COMRECT rect = new COMRECT(); rect.left = 0; rect.top = 0; rect.right = widthsize; rect.bottom = heightsize; IntPtr hDC = gFinal.GetHdc(); IViewObject vO = myDoc as IViewObject; vO.Draw(1, -1, (IntPtr)0, (IntPtr)0, (IntPtr)0, (IntPtr)hDC, ref rect, (IntPtr)0, (IntPtr)0, 0); gFinal.ReleaseHdc(); gFinal.Dispose(); return finalImage; } I am not getting the image of the webpage. Rather I am getting an image with black background. I am not sure if this is the right way of doing it, but I found over the web that IViewObject::Draw method is used for taking the image of a webpage in IE. I was earlier doing the image capture using the Native PrintWindow() method as mentioned in the following codeproject's page - http://www.codeproject.com/KB/graphics/IECapture.aspx But the image size is humongous! I was trying to see if I can reduce the size by using other techniques. It would be great if someone can point out the mistakes (I am sure there would be many) in my code above. Thanks, Kapil

  • Traversing/Manipulating new window from parent window with jquery

    - by Anthony
    I found a question already with a possible solution, but I had already tried the method suggested before reading it, and it even says it's inconsistent. So I guess I'm wondering why this doesn't work: $("img").click(function() { var imgwindow = window.open('imgwin.html','','width=460,height=345'); alert(imgwindow.find("img").attr("src")); }); The goal is to set the new window's img to the same src as the image that the user clicked to open the new window. But in the above scenario, I'm just trying to tap into the new window to get what it's already-set src. I have imgwin.html already written with a default src for the image, so it should alert that url. Instead I just get undefined. I also tried the following (which should be identical on the back end), but with the same results: $("img").click(function() { var imgwindow = window.open('imgwin.html','','width=460,height=345'); alert($("img",imgwindow).attr("src")); }); I even tried variations of wrapping the imgwindow variable in $() in case somehow jquery wasn't picking up on the variable as a DOM element. The only thing I can guess is that since window.open() is a method, jquery doesn't treat it like a DOM element, even though all documentation from basic javascript tutorials treat the variable as both a method to open the window and the pointer to the window's inner DOM.

  • Play a sound based on the button pressed on the IPhone/xcode.

    - by slickplaid
    I'm trying to play a sound based on which button is pressed using AVAudioPlayer. (This is not a soundboard or fart app.) I have linked all buttons using this code in the header file: @interface appViewController : UIViewController <AVAudioPlayerDelegate> { AVAudioPlayer *player; UIButton *C4; UIButton *Bb4; UIButton *B4; UIButton *A4; UIButton *Ab4; UIButton *As4; UIButton *G3; UIButton *Gb3; UIButton *Gs3; UIButton *F3; UIButton *Fs3; UIButton *E3; UIButton *Eb3; UIButton *D3; UIButton *Db3; UIButton *Ds3; UIButton *C3; UIButton *Cs3; } @property (nonatomic, retain) AVAudioPlayer *player; @property (nonatomic, retain) IBOutlet UIButton *C4; @property (nonatomic, retain) IBOutlet UIButton *B4; @property (nonatomic, retain) IBOutlet UIButton *Bb4; @property (nonatomic, retain) IBOutlet UIButton *A4; @property (nonatomic, retain) IBOutlet UIButton *Ab4; @property (nonatomic, retain) IBOutlet UIButton *As4; @property (nonatomic, retain) IBOutlet UIButton *G3; @property (nonatomic, retain) IBOutlet UIButton *Gb3; @property (nonatomic, retain) IBOutlet UIButton *Gs3; @property (nonatomic, retain) IBOutlet UIButton *F3; @property (nonatomic, retain) IBOutlet UIButton *Fs3; @property (nonatomic, retain) IBOutlet UIButton *E3; @property (nonatomic, retain) IBOutlet UIButton *Eb3; @property (nonatomic, retain) IBOutlet UIButton *D3; @property (nonatomic, retain) IBOutlet UIButton *Db3; @property (nonatomic, retain) IBOutlet UIButton *Ds3; @property (nonatomic, retain) IBOutlet UIButton *C3; @property (nonatomic, retain) IBOutlet UIButton *Cs3; - (IBAction) playNote; @end Buttons are all linked to the event "playNote" in interfaceBuilder and each note is linked to the proper referencing outlet according to note name. All *.mp3 sound files are named after the UIButton name (IE- C3 == C3.mp3). In my implementation file, I have this to play a only one note when the C3 button is pressed: #import "sonicfitViewController.h" @implementation appViewController @synthesize C3, Cs3, D3, Ds3, Db3, E3, Eb3, F3, Fs3, G3, Gs3, A4, Ab4, As4, B4, Bb4, C4; // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"3C" ofType:@"mp3"]; NSLog(@"path: %@", path); NSURL *file = [[NSURL alloc] initFileURLWithPath:path]; AVAudioPlayer *p = [[AVAudioPlayer alloc] initWithContentsOfURL:file error:nil]; [file release]; self.player = p; [p release]; [player prepareToPlay]; [player setDelegate:self]; [super viewDidLoad]; } - (IBAction) playNote { [self.player play]; } Now, with the above I have two issues: First, the NSLog reports NULL and crashes when trying to play the file. I have added the mp3's to the resources folder and they have been copied and not just linked. They are not in an subfolder under the resources folder. Secondly, how can I set it up so that when say button C3 is pressed, it plays C3.mp3 and F3 plays F3.mp3 without writing duplicate lines of code for each different button? playNote should be like NSString *path = [[NSBundle mainBundle] pathForResource:nameOfButton ofType:@"mp3"]; instead of defining it specifically (@"C3"). Is there a better way of doing this and why does the *path report NULL and crash when I load the app? I'm pretty sure it's something as simple as adding additional variable inputs to - (IBAction) playNote:buttonName and putting all the code to call AVAudioPlayer in the playNote function but I'm unsure of the code to do this.

  • 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]; }

  • Perl on MacOS X 10.6.2: GDBM_File missing, how to install or work around?

    - by jdmuys
    When I need a Perl module, I typically use CPAN. It works fine. But not this time. I want to use MARC::Charset, but this one uses GDBM_File, and I can't seem to install GDBM_File from CPAN. CPAN finds it all right, but trying to install it, it starts installing the full Perl 5.10.1 distribution. MARC::Charset is a rather old module, so there should be a way to use it from some common Perl version (Mac OS X 10.6.2 has 5.10.0 and 5.8.9 by default). While installing the full blow Perl 5.10.1 is not an option, modifying MARC::Charset to stop using GDBM_File might be one. What would be the best course of action to do so? This last option might also be the only one. googling GDBM_File uncovers a few items that suggest that gdbm is not even available on the Mac. Those items typically went over my head though. While I don't expect a silver bullet, somebody may have a pointer or two on where I should start. After all, MARC::Charset only does character transliteration to/from the marc8 char set, which unfortunately, iconv doesn't seem to support.

  • Threading 101: What is a Dispatcher?

    - by Water Cooler v2
    Once upon a time, I remembered this stuff by heart. Over time, my understanding has diluted and I mean to refresh it. As I recall, any so called single threaded application has two threads: a) the primary thread that has a pointer to the main or DllMain entry points; and b) For applications that have some UI, a UI thread, a.k.a the secondary thread, on which the WndProc runs, i.e. the thread that executes the WndProc that recieves messages that Windows posts to it. In short, the thread that executes the Windows message loop. For UI apps, the primary thread is in a blocking state waiting for messages from Windows. When it recieves them, it queues them up and dispatches them to the message loop (WndProc) and the UI thread gets kick started. As per my understanding, the primary thread, which is in a blocking state, is this: C++ while(getmessage(/* args &msg, etc. */)) { translatemessage(&msg, 0, 0); dispatchmessage(&msg, 0, 0); } C# or VB.NET WinForms apps: Application.Run( new System.Windows.Forms() ); Is this what they call the Dispatcher? My questions are: a) Is my above understanding correct? b) What in the name of hell is the Dispatcher? c) Point me to a resource where I can get a better understanding of threads from a Windows/Win32 perspective and then tie it up with high level languages like C#. Petzold is sparing in his discussion on the subject in his epic work. Although I believe I have it somewhat right, a confirmation will be relieving.

  • Extra text shown on oveflow: hidden

    - by TRiG
    I'm keeping the main content area of the webpage small, so that footer navigation can be seen "above the fold". This is done by javascript setting the main content <div> thus: sec.style.height = '265px'; sec.style.overflow = 'hidden'; And then using javascript to insert a button to change the style back to normal: sec.style.height = 'auto'; The problem is that the cut-off point of 265px (dictated by the size of an image which I don't want to hide) doesn't quite match the gap between lines of text. This means that there the tops of tall letters show as funny little marks. Is there any way to hide text which is partially showing in a <div style="overflow: hidden;">? Edit to add: Full javascript var overflow = { hide: function() { var sec = app.get('content_section'); sec.style.height = '263px'; sec.style.overflow = 'hidden'; overflow.toggle(false); }, toggle: function(value) { var cnt = app.get('toggle_control'); if (value) { var func = 'hide'; cnt.innerHTML = 'Close « '; } else { var func = 'show'; cnt.innerHTML = 'More » '; } cnt.onclick = function() {eval('overflow.' + func + '();'); return false;}; cnt.style.cursor = 'pointer'; cnt.style.fontWeight = 'normal'; cnt.style.margin = '0 0 0 857px'; }, show: function() { var sec = app.get('content_section'); sec.style.height = 'auto'; overflow.toggle(true); } } if (document.addEventListener) { document.addEventListener('DOMContentLoaded', overflow.hide, false); } else { window.onload = function() {return overflow.hide();}; }

  • c# opennetCF background worker - e.result gives a ObjectDisposedException

    - by ikky
    Hi! I'm new working with background worker in C#. Here is a class, and under it, you will find the instansiation of it, and under there i will define my problem for you: I have the class Drawing: class Drawing { BackgroundWorker bgWorker; ProgressBar progressBar; Panel panelHolder; public Drawing(ref ProgressBar pgbar, ref Panel panelBig) // Progressbar and panelBig as reference { this.panelHolder = panelBig; this.progressBar = pgbar; bgWorker = new BackgroundWorker(); bgWorker.WorkerReportsProgress = true; bgWorker.WorkerSupportsCancellation = true; bgWorker.DoWork += new OpenNETCF.ComponentModel.DoWorkEventHandler(this.bgWorker_DoWork); bgWorker.RunWorkerCompleted += new OpenNETCF.ComponentModel.RunWorkerCompletedEventHandler(this.bgWorker_RunWorkerCompleted); bgWorker.ProgressChanged += new OpenNETCF.ComponentModel.ProgressChangedEventHandler(this.bgWorker_ProgressChanged); } public void createDrawing() { bgWorker.RunWorkerAsync(); } private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { Panel panelContainer = new Panel(); // Adding panels to the panelContainer for(i=0; i<100; i++) { Panel panelSubpanel = new Panel(); // Setting size, color, name etc.... panelContainer.Controls.Add(panelSubpanel); // Adding the subpanel to the panelContainer //Report the progress bgWorker.ReportProgress(0, i); // Reporting number of panels loaded } e.Result = imagePanel; // Send the result(a panel with lots of subpanels) as an argument } private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { this.progressBar.Value = (int)e.UserState; this.progressBar.Update(); } private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Error == null) { this.panelHolder = (Panel)e.Result; } else { MessageBox.Show("An error occured, please try again"); } } } Instansiating an object of this class: public partial class Draw: Form { public Draw() { ProgressBar progressBarLoading = new ProgressBar(); // Set lots of properties on progressBarLoading Panel panelBigPanelContainer = new Panel(); Drawing drawer = new Drawing(ref progressBarLoading, ref panelBigPanelContainer); drawer.createDrawing(); // this makes the object start a new thread, loading all the panels into a panel container, while also sending the progress to this progressbar. } } Here is my problem: In the private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) i don't get the e.Result as it should be. When i debug and look at the e.Result, the panel's properties have this exception message: '((System.Windows.Forms.Control)(e.Result)).ClientSize' threw an exception of type 'System.ObjectDisposedException' So the object gets disposed, but "why" is my question, and how can i fix this? I hope someone will answer me, this is making me crazy. Another question i have: Is it allowed to use "ref" with arguments? is it bad programming? Thanks in advance. I have also written how i understand the Background worker below here: This is what i think is the "rules" for background workers: bgWorker.RunWorkerAsync(); => starts a new thread. bgWorker_DoWork cannot reach the main thread without delegates - private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { // The work happens here, this is a thread that is not reachable by the main thread e.Result => This is an argument which can be reached by bgWorker_RunWorkerCompleted() bgWorker.ReportProgress(progressVar); => Reports the progress to the bgWorker_ProgressChanged() } - private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { // I get the progress here, and can do stuff to the main thread from here (e.g update a control) this.ProgressBar.Value = e.ProgressPercentage; } - private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { // This is where the thread is completed. // Here i can get e.Result from the bgWorker thread // From here i can reach controls in my main thread, and use e.Result in my main thread if (e.Error == null) { this.panelTileHolder = (Panel)e.Result; } else { MessageBox.Show("There was an error"); } }

  • Linux Device Driver - what's wrong with my device_read()?

    - by Rob
    My device /dev/my_inc is meant to take a positive integer N represented as an ascii string, and store it. Any read from /dev/my_inc will produce the ascii string representation of N + 1. The problem is that when I cat /dev/my_inc, I only get the first byte of myinc_value output to my shell, even though I have bytes_read == 2 at the end of my loop. /* Read from the device *********************/ static ssize_t device_read(struct file *filp, char *buffer, size_t length, loff_t *offset) { char c; int bytes_read = 0; int value = myinc_value + 1; printk(KERN_INFO "my_inc device_read() called with value %d and msg %s.\n", value, msg); /* No bytes read if pointer to 0 */ if (*msg_ptr == 0) return 0; /* Put the incremented value in msg */ snprintf(msg, MAX_LENGTH, "%d", value); /* Put bytes from msg into user space buffer */ while (length && *msg_ptr) { c = *(msg_ptr++); printk(KERN_INFO "%s device_read() read %c.", DEV_NAME, c); if(put_user(c, buffer++)) return -EFAULT; length--; bytes_read++; } printk("my_inc device_read() returning %d.\n", bytes_read); /* Return bytes copied */ return bytes_read; }

  • jquery ui slider IE7 bug...

    - by Reigel
    When you are holding the handles to slide them the width of the range blows out to 100% width, but snaps back to the width it's supposed to be once you release the handle. jQuery 1.4.2 UI 1.8.2 please help jQuery if ($("#topImageSlider").length){ var max = 120; var initialValue = 40; function refreshValue(){ //$('#sliderValue .current').text($("#topImageSlider").slider("value")); $('#sliderValue .current').text($('.ui-slider-range').width()); } $("#topImageSlider").slider({ orientation: 'horizontal', range: "min", max: max, min: 1, value: initialValue, slide: refreshValue, change: refreshValue }).after('<div id="sliderValue"><span class="current">'+ initialValue +'</span> / <span class="max">'+ max +'</span></div>'); } css #topImageSlider, #sliderValue { margin: 0 auto; width: 572px; text-align: center; } #topImageSlider { margin-top: 20px; background: url(../img/bg/slider.png) no-repeat; height: 5px; } #topImageSlider .ui-slider-range { background: url(../img/bg/slider-progress.gif) repeat-x; left: 2px; height: 5px; } #topImageSlider .ui-slider-handle { background: url(../img/btn/slider-handle.png) no-repeat; width: 24px; height: 24px; top: -8px; outline: 0; cursor: pointer; z-index: 999; } #sliderValue { margin-top: 10px; color: #bbb; font-weight: bold; } #sliderValue .current { color: #ff6e0d; }

  • Android using ksoap calling PHP SOAP webservice fails: 'procedure 'CheckLogin' not found

    - by AmazingDreams
    I'm trying to call a PHP SOAP webservice. I know my webservice functions correctly because I use it in a WPF project succesfully. I'm also building an app in android, using the same webservice. The WSDL file can be found here: http://www.wegotcha.nl/servicehandler/service.wsdl This is my code in the android app: String SOAP_ACTION = "http://www.wegotcha.nl/servicehandler/CheckLogin"; String NAMESPACE = "http://www.wegotcha.nl/servicehandler"; String METHOD_NAME = "CheckLogin"; String URL = "http://www.wegotcha.nl/servicehandler/servicehandler.php"; String resultData = ""; SoapSerializationEnvelope soapEnv = new SoapSerializationEnvelope(SoapEnvelope.VER11); SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapObject UserCredentials = new SoapObject("Types", "UserCredentials6"); UserCredentials.addProperty("mail", params[0]); UserCredentials.addProperty("password", md5(params[1])); request.addSoapObject(UserCredentials); soapEnv.setOutputSoapObject(request); HttpTransportSE http = new HttpTransportSE(URL); http.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>"); http.debug = true; try { http.call(SOAP_ACTION, soapEnv); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } SoapObject results = null; results = (SoapObject)soapEnv.bodyOut; if(results != null) resultData = results.getProperty(0).toString(); return resultData; Using fiddler I got the following: Android request: <?xml version="1.0" encoding="utf-8"?> <v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/"><v:Header /> <v:Body> <n0:CheckLogin id="o0" c:root="1" xmlns:n0="http://www.wegotcha.nl/servicehandler"> <n1:UserCredentials6 i:type="n1:UserCredentials6" xmlns:n1="Types"> <mail i:type="d:string">myemail</mail> <password i:type="d:string">myhashedpass</password> </n1:UserCredentials6> </n0:CheckLogin> </v:Body> </v:Envelope> Getting the following response: Procedure 'CheckLogin' not present My request produced by my WPF app looks completely different: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <UserCredentials6 xmlns="Types"> <mail>mymail</mail> <password>mypassword</password> </UserCredentials6> </s:Body> </s:Envelope> After googling my ass off I was not able to solve this problem by myself. It may be possible there are some weird things in my Java code because I changed a lot since. I hope you guys will be able to help me, thanks. EDIT: My webservice is of document/literal encoding style, after doing some research I found I should be able to use SoepEnvelope Instead of SoapSerializationEnvelope Though when I replace this I get an error before the try cache block, causing my app to crash. Error: 11-04 16:23:26.786: E/AndroidRuntime(26447): Caused by: java.lang.ClassCastException: org.ksoap2.serialization.SoapObject cannot be cast to org.kxml2.kdom.Node Which is caused by these lines: request.addSoapObject(UserCredentials); soapEnv.setOutputSoapObject(request); This may be a solution though, how do I go about this? I found nothing about using a SoapEnvelope instead of a SoapSerializationEnvelope except for this awesome tutorial: http://ksoap.objectweb.org/project/mailingLists/ksoap/msg00849.html

  • UINavigationController crash because of pushing and poping UIViewControllers

    - by Wayne Lo
    My question is related to my discovery of a reason for UINavigationController to crash. So I will tell you about the discovery first. Please bare with me. The issue: I have a UINavigationController as as subview of UIWindow, a rootViewController class and a custom MyViewController class. The following steps will get a Exc_Bad_Access, 100% reproducible.: [myNaviationController pushViewController:myViewController_1stInstance animated:YES]; [myNaviationController pushViewController:myViewController_2ndInstance animated:YES]; Hit the left back tapBarItem twice (pop out two of the myViewController instances) to show the rootViewController. After a painful 1/2 day of try and error, I finally figure out the answer but also raise a question. The Solutio: I declared many objects in the .m file as a lazy way of declaring private variables to avoid cluttering the .h file. For instance, #impoart "MyViewController.h" NSMutableString*variable1; @implement ... -(id)init { ... varialbe1=[[NSMutableString alloc] init]; ... } -(void)dealloc { [variable1 release]; } For some reasons, the iphone OS may loose track of these "lazy private" variables memory allocation when myViewController_1stInstance's view is unloaded (but still in the navigation controller's stacks) after loading the view of myViewController_2ndInstance. The first time to tap the back tapBarItem is ok since myViewController_2ndInstance'view is still loaded. But the 2nd tap on the back tapBarItem gave me hell because it tried to dealloc the 2nd instance. Executing [variable release] resulted in Exc_Bad_Access because it pointed randomly (loose pointer). To fix this problem is simple, declare variable1 as a @private in the .h file. Here is my Question: I have been using the "lazy private" variables for quite some time without any issues until they are involved in UINavigationController. Is this a bug in iPhone OS? Or there is a fundamental misunderstanding on my part about Objective C? Please help.

  • jQuery Drag/Drop problem: mousemove Event not binding for some elements

    - by saturdayplace
    Using the latest jQuery/UI that are hosted at Google. I've got the following markup: <ul id="tree"> <li><a href="1/">One</a></li> <li><a href="2/">Two</a></li> </ul> And the following javascript: $(document).ready(function(){ // Droppable callbacks function dragOver(overEvent, ui_object) { $(this).mousemove(function(moveEvent){ console.log("moved over", this); }); } function drop_deactivate() { $(this).unbind(); } function drag_out() { $(this).unbind(); } // Actual dragging $("#treeContainer li").draggable({ revert: true, revertDuration: 0 }); // Actuall dropping $("a").droppable({ tolerance: "pointer", over: dragOver, deactivate: drop_deactivate, out: drag_out }); }); If I drag the first li down over the second, the mousemove function fires (and firebug logs the output). But if I drag the second li up over the first, the mousemove function doesn't fire. You can see this live at http://jsbin.com/ivala. Is there a reason for this? Should I be trapping the mousemove event in some other way? Edit: It appears as thought the mousemove() event isn't binding for earlier elements than the one currently being dragged (should be bound upon their mouseover).
