  • WPF: Update Listbox automatically C#

    - by Ashley
    Hi, I have two WPF windows developed using the surface SDK, one that is a data entry form, and the second dispays the data in a listbox. The listbox displays the data perfectly but when I add a new record using the data entry form, the listbox is not updated until I reopen the window. Is there a way to automatically update the listbox through binding or something? This is the listbox code: <s:SurfaceListBox Height="673" Margin="0,26,0,31" Name="surfaceListBox1" ItemsSource="{Binding Path={}}" Width="490"> <s:SurfaceListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Label Width="80" FontSize="8" Content="{Binding Path=item1}"></Label> <Label Width="80" FontSize="8" Content="{Binding Path=item2}"></Label> <Label Width="210" FontSize="8" Content="{Binding Path=item3}"></Label> <Label Width="80" FontSize="8" Content="{Binding Path=item4}"></Label> <Label Width="60" FontSize="8" Content="{Binding Path=item5, Converter={StaticResource booleanconverter}}"></Label> </StackPanel> </DataTemplate> </s:SurfaceListBox.ItemTemplate> </s:SurfaceListBox> I am using Visual C# 2008 and the code to fill the listbox is: private SHIPS_LOGDataSet ShipData = new SHIPS_LOGDataSet(); private SHIPS_LOGDataSetTableAdapters.MAINTableAdapter taMain = new SHIPS_LOGDataSetTableAdapters.MAINTableAdapter(); private SHIPS_LOGDataSetTableAdapters.TableAdapterManager taManager = new ShipsLogSurface.SHIPS_LOGDataSetTableAdapters.TableAdapterManager(); private void SurfaceWindow_Loaded(object sender, RoutedEventArgs e) { this.taMain.Fill(this.ShipData.MAIN); this.DataContext = from MAIN in this.ShipData.MAIN orderby MAIN.MESSAGE_ID descending select MAIN; } The only table in my database is called MAIN. I'm guessing I might have to use a collection view or similar but don't know how to implement that. Any ideas would be much appreciated. Thanks

  • XmlSerializer one Class that has multiple classes properties

    - by pee2002
    Hi there! Objective: Serialize all the public properties of the ClassMain: public class ClassMain { ClassA classA = new ClassA(); public ClassMain() { classA.Prop1 = "Prop1"; classA.Prop2 = "Prop2"; } public string Prop1 { get; set; } public string Prop2 { get; set; } public ClassA ClassA { get { return classA; } } } ClassA: public class ClassA { public string Prop1 { get; set; } public string Prop2 { get; set; } } This is how i´m serializing: private void button1_Click(object sender, EventArgs e) { ClassMain classMain = new ClassMain(); classMain.Prop1 = "Prop1"; classMain.Prop2 = "Prop2"; XmlSerializer mySerializer = new XmlSerializer(typeof(ClassMain)); StreamWriter myWriter = new StreamWriter("xml1.xml"); mySerializer.Serialize(myWriter, classMain); myWriter.Close(); } In this case, the xml output is: <?xml version="1.0" encoding="utf-8"?> <ClassMain xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Prop1>Prop1</Prop1> <Prop2>Prop2</Prop2> </ClassMain> As you see, is lacking the ClassA properties. Can anyone help me out? Regards

  • Java and AppStore receipt verification

    - by user1672461
    I am trying to verify a payment receipt on server side. I am getting a {"status":21002, "exception":"java.lang.IllegalArgumentException"} in return Here is the code: private final static String _sandboxUriStr = "https://sandbox.itunes.apple.com/verifyReceipt"; public static void processPayment(final String receipt) throws SystemException { final BASE64Encoder encoder = new BASE64Encoder(); final String receiptData = encoder.encode(receipt.getBytes()); final String jsonData = "{\"receipt-data\" : \"" + receiptData + "\"}"; System.out.println(receipt); System.out.println(jsonData); try { final URL url = new URL(_productionUriStr); final HttpURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setRequestMethod("POST"); conn.setDoOutput(true); final OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream()); wr.write(jsonData); wr.flush(); // Get the response final BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream())); String line; while ((line = rd.readLine()) != null) { System.out.println(line); } wr.close(); rd.close(); } catch (IOException e) { throw new SystemException("Error when trying to send request to '%s', %s", _sandboxUriStr, e.getMessage()); } } My receipt looks like this: {\n\t"signature" = "[exactly_1320_characters]";\n\t"purchase-info" = "[exactly_868_characters]";\n\t"environment" = "Sandbox";\n\t"pod" = "100";\n\t"signing-status" = "0";\n} Receipt data with a BASE64 encoded receipt looks like this: Blockquote {"receipt-data" : "[Block_of_chars_76x40+44=3084_chars_total]"} Does someone have an Idea, or sample code how can I get from receipt string to reply JSON, mentioned here: [http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/VerifyingStoreReceipts/VerifyingStoreReceipts.html#//apple_ref/doc/uid/TP40008267-CH104-SW1]?

  • adding UIImageView to UIScrollView throws exception cocoa touch for iPad

    - by Brodie4598
    I am a noob at OBJ-C :) I am trying to add a UIImageView to a UIScrollView to display a large image in my iPad app. I have followed the tutorial here exactly: http://howtomakeiphoneapps.com/2009/12/how-to-use-uiscrollview-in-your-iphone-app/ The only difference is that in my App the View is in a seperate tab and I am using a different image. here is my code: - (void)viewDidLoad { [super viewDidLoad]; UIImageView *tempImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Cheyenne81"]]; self.imageView = tempImageView; [tempImageView release]; scrollView.contentSize = CGSizeMake(imageView.frame.size.width, imageView.frame.size.height); scrollView.maximumZoomScale = 4.0; scrollView.minimumZoomScale = 0.75; scrollView.clipsToBounds = YES; scrollView.delegate = self; [scrollView addSubview:imageView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{ return imageView; } and: @interface UseScrollViewViewController : UIViewController<UIScrollViewDelegate>{ IBOutlet UIScrollView *scrollView; UIImageView *imageView; } @property (nonatomic, retain) UIScrollView *scrollView; @property (nonatomic, retain) UIImageView *imageView; @end I then create a UIScrollView in Interface Builder and link it to the scrollView outlet. Thats when I get the problem. When I run the program it crashes instantly. If I run it without linking the scrollView to the outlet, it will run (allbeit with a blnk screen). The following is the error I get in the console: 2010-03-27 20:18:13.467 UseScrollViewViewController[7421:207] * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key scrollView.'

  • InvalidOperationException when calling SaveChanges in .NET Entity framework

    - by Pär Björklund
    Hi, I'm trying to learn how to use the Entity framework but I've hit an issue I can't solve. What I'm doing is that I'm walking through a list of Movies that I have and inserts each one into a simple database. This is the code I'm using private void AddMovies(DirectoryInfo dir) { MovieEntities db = new MovieEntities(); foreach (DirectoryInfo d in dir.GetDirectories()) { Movie m = new Movie { Name = d.Name, Path = dir.FullName }; db.AddToMovies(movie); } db.SaveChanges(); } When I do this I get an exception at db.SaveChanges() that read. The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. I haven't been able to find out what's causing this issue. My database table contains three columns Id int autoincrement Name nchar(255) Path nchar(255) Update: I Checked my edmx file and the SSDL section have the StoreGeneratedPattern="Identity" as suggested. I also followed the blog post and tried to add ClientAutoGenerated="true" and StoreGenerated="true" in the CSDL as suggested there. This resulted in compile errors ( Error 5: The 'ClientAutoGenerated' attribute is not allowed.). Since the blog post is from 2006 and it has a link to a follow up post I assume it's been changed. However, I cannot read the followup post since it seems to require an msdn account.

  • Refresh UltraGrid's GroupBy Sort on child bands when ListChanged?

    - by Idriss
    I am using Infragistics 2009 vol 1. My UltraGrid is bound to a BindingList of business objects "A" having themself a BindingList property of business objects "B". It results in having two bands: one named "BindingList`1", the other one "ListOfB" thanks to the currency manager. I would like to refresh the GroupBy sort of the grid whenever a change is performed on the child band through the child business object and INotifyPropertyChange. If I group by a property in the child band which is a boolean (let's say "Active") and I subscribe to the event ListChanged on the bindinglist datasource with this event handler: void Grid_ListChanged(object sender, ListChangedEventArgs e) { if (e.ListChangedType == ListChangedType.ItemChanged) { string columnKey = e.PropertyDescriptor.Name; if (e.PropertyDescriptor.PropertyType.Name == "BindingList`1") { ultraGrid.DisplayLayout.Bands[columnKey].SortedColumns.RefreshSort(true); } else { UltraGridBand band = ultraGrid.DisplayLayout.Bands[0]; UltraGridColumn gc = band.Columns[columnKey]; if (gc.IsGroupByColumn || gc.SortIndicator != SortIndicator.None) { band.SortedColumns.RefreshSort(true); } ColumnFilter cf = band.ColumnFilters[columnKey]; if (cf.FilterConditions.Count > 0) { ultraGrid.DisplayLayout.RefreshFilters(); } } } } the band.SortedColumns.RefreshSort(true) is called but It gives unpredictable results in the groupby area when the property Active is changed in the child band: if one object out of three actives becomes inactive it goes from: Active : True (3 items) To: Active : False (3 items) Instead of (which is the case when I drag the column back and forth to the group by area) Active : False (1 item) Active : True (2 items) Am I doing something wrong? Is there a way to restore the expanded state of the rows when performing a RefreshSort(true); ?

  • Android: Adding extended GLSurfaceView to a Layout don't show 3d stuff

    - by Santiago
    I make a game extending the class GLSurfaceView, if I apply SetContentView directly to that class, the 3d stuff and input works great. Now I want to show some items over 3d stuff, so I create a XML with a layout and some objects, and I try to add my class manually to the layout. I'm not getting errors but the 3d stuff is not shown but I can view the objects from XML layout. source: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); layout = (RelativeLayout) inflater.inflate(R.layout.testlayout, null); //Create an Instance with this Activity my3dstuff = new myGLSurfaceViewClass(this); layout.addView(my3dstuff,4); setContentView(R.layout.testlayout); } And testlayout have: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/Pantalla"> <ImageView android:id="@+id/zoom_less" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/zoom_less"></ImageView> <ImageView android:id="@+id/zoom_more" android:layout_width="wrap_content" android:src="@drawable/zoom_more" android:layout_height="wrap_content" android:layout_alignParentRight="true"></ImageView> <ImageView android:id="@+id/zoom_normal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/zoom_normal" android:layout_centerHorizontal="true"></ImageView> <ImageView android:id="@+id/stop" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/stop" android:layout_centerInParent="true" android:layout_alignParentBottom="true"></ImageView> </RelativeLayout> I also tried to add my class to XML but the Activity hangs up. <com.mygame.myGLSurfaceViewClass android:id="@+id/my3dstuff" android:layout_width="fill_parent" android:layout_height="fill_parent"></com.mygame.myGLSurfaceViewClass> and this don't works: <View class="com.mygame.myGLSurfaceViewClass" android:id="@+id/my3dstuff" android:layout_width="fill_parent" android:layout_height="fill_parent"></View> Any Idea?

  • ConcurrentDictionary and updating values

    - by rboarman
    Hello, After searching via Google and coming up empty, I decided to ask the gurus here on StackOverflow. I am trying to update entries in a ConcurrentDictionary something like this: class Class1 { public int Counter { get; set; } } class Test { private ConcurrentDictionary<int, Class1> dict = new ConcurrentDictionary<int, Class1>(); public void TestIt() { foreach (var foo in dict) { foo.Value.Counter = foo.Value.Counter + 1; // Simplified example } } } Essentially I need to iterate over the dictionary and update a field on each Value. I understand from the documentation that I need to avoid using the Value property. Instead I think I need to use TryUpdate except that I don’t want to replace my whole object. Instead, I want to update a field on the object. After reading this: http://blogs.msdn.com/b/pfxteam/archive/2010/01/08/9945809.aspx Perhaps I need to use AddOrUpdate and simply do nothing in the add delegate. Does anyone have any insight as to how to do this? Thank you, Rick

  • Add a row to UITableView for adding new item?

    - by David.Chu.ca
    In order to provide UI for user to add new items to my table view, I would like to add a new row in my table at a specified location (last row for example) when the view is in edit mode (I have a edit button on the view's navigation bar right side). This new row will have a add button indicator on the left side and disclosure accessory arrow on the right. When the view is not in edit mode, this add row should not be displayed. I am not sure if I should overwrite: - (void)setEditing:(BOOL)editing animated:(BOOL)animated{...} where I call the UITableView's method: insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation: (UITableViewRowAnimation)animation to insert a new row? My understanding is that this call may add a new row into the table view. The table view's data source is from CoreData storage. Not sure this may cause inconsistent numbers of data in the data store and table view? If it is OK and I have to manage rows in the table view, how can I add left add indicator and left disclosure arrow to the new row? Another question is that if I can do it to insert a new row as Add row, should I remove it when the table view not in edit mode? Just want to know if I am on the right track.

  • SignalR - No connection could be made because the target machine actively refused it?

    Trying to create a Console application that is going to send data to a website. The website is built with Codeiginter framework, if that matters. When i'm running my Console application, i get the error that a connection could not be made, and that the machine refused it. Been watching some tutorials, but most of them are using Hubs etc, which imo i do not need for this simple task?. All i want to do is to send data to the website, one way.

  • How to change StartupUri of WPF Application?

    - by Akash Kava
    I am trying to modify App.cs and load the WPF XAML files from code behind but its not working as it should. No matter whatever I try to set as StartupUri it doesnt start, the program quits after this. public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); LoginDialog dlg = new LoginDialog(); if (dlg.ShowDialog() != true) return; switch (dlg.ChoiceApp) { case ChoiceApp.CustomerEntry: StartupUri = new Uri("/MyApp;component/Forms/CustomerEntry.xaml", UriKind.Relative); break; case ChoiceApp.VendorEntry: StartupUri = new Uri("/MyApp;component/Forms/VendorEntry.xaml", UriKind.Relative); break; } } } Now I even did trace and found out that LoginDialog is working correctly and is returning values correctly but setting "StartupUri" does not work. I checked in reverse assembly that DoStartup method of App gets called after OnStartup, so technically my StartupUri must load, but it doesnt, in App.xaml startup uri is not at all defined. Note: Bug Confirmed I noticed that ShowDialog sets Application.MainWindow and when dialog ends, it sets it back to null, and because of this setting StartupUri does not work after calling Modal Dialog in OnStartup or Startup event. There is no error or exception about invalid uri or anything like that. This method works without DialogBox being called in Startup event or OnStartup, i think calling showdialog on this method causes something like its mainwindow being set to expired window and it shuts down after this.

They are presented as IEnumerable, and are requested from the a repository with GetLookup(LookupId). I have created a custom attribute that I have decorated my MetaDataClass that looks something like this: [Lookup(Lookup.Products)] public Guid ProductId I have created a custom Data Form that is set to AutoGenerateFields and I am intercepting the autogenerate fields. I am checking for my CustomAttribute and that works. Given this code in my CustomDataForm (standard comments removed for brevity), what is the next step to override the field generation and place a bound combobox in its place? public class CustomDataForm : DataForm { private Dictionary<string, DataField> fields = new Dictionary<string, DataField>(); public Dictionary<string, DataField> Fields { get { return this.fields; } } protected override void OnAutoGeneratingField(DataFormAutoGeneratingFieldEventArgs e) { PropertyInfo propertyInfo = this.CurrentItem.GetType().GetProperty(e.PropertyName); foreach (Attribute attribute in propertyInfo.GetCustomAttributes(true)) { LookupFieldAttribute lookupFieldAttribute = attribute as LookupFieldAttribute; if (lookupFieldAttribute != null) { // Create a combo box. // Bind it to my Lookup IEnumerable // Set the selected item to my Field's Value // Set the binding two way } } this.fields[e.PropertyName] = e.Field; base.OnAutoGeneratingField(e); } } Any cited working examples for SL4/VS2010 would be appreciated. Thanks

  • Need to override drawrect if your UIView is merely a container?

    - by Greg Maletic
    According to Apple's docs, "Subclasses need not override -[UIView drawRect:] if the subclass is a container for other views." I have a custom UIView subclass that is indeed merely a container for other views. Yet the contained views aren't getting drawn. Here's the pertinent code that sets up the custom UIView subclass: - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Consists of both an "on" light and an "off" light. We flick between the two depending upon our state. self.onLight = [[[LoyaltyCardNumberView alloc] initWithFrame:frame] autorelease]; self.onLight.backgroundColor = [UIColor clearColor]; self.onLight.on = YES; [self addSubview:self.onLight]; self.offLight = [[[LoyaltyCardNumberView alloc] initWithFrame:frame] autorelease]; self.offLight.backgroundColor = [UIColor clearColor]; self.offLight.on = NO; [self addSubview:self.offLight]; self.on = NO; } return self; } When I run the code that displays this custom UIView, nothing shows up. But when I add a drawRect method... - (void)drawRect:(CGRect)rect { [self.onLight drawRect:rect]; [self.offLight drawRect:rect]; } ...the subviews display. (Clearly, this isn't the right way to be doing this, not only because it's contrary to what the docs say, but because it -always- displays both subviews, completely ignoring some other code in my UIView that sets the hidden property of one of the views, it ignores the z-ordering, etc.) Anyway, the main question: why don't my subviews display when I'm not overriding drawRect:? Thanks!

  • PDF rendering crashes app Core Graphics

    - by Felixyz
    EDIT: The memory leaks turned out to be unrelated to the crashes. Leaks are fixed but crashes remain, still mysterious. My (iPhone) app does lots of PDF loading and rendering, some of it threaded. Sometime, it seems always after I flush a page cash after getting a memory warning, the app crashes with a bad access when trying to draw a pdf page stored in an NSData object. Here is one example trace: #0 0x3016d564 in CGPDFResourcesGetResource () #1 0x3016d58a in CGPDFResourcesGetResource () #2 0x3016d94e in CGPDFResourcesGetExtGState () #3 0x3015fac4 in CGPDFContentStreamGetExtGState () #4 0x301629a8 in op_gs () #5 0x3016df12 in handle_xname () #6 0x3016dd9e in read_objects () #7 0x3016de6c in CGPDFScannerScan () #8 0x30161e34 in CGPDFDrawingContextDraw () #9 0x3016a9dc in CGContextDrawPDFPage () But sometimes I get this instead: Program received signal: “EXC_BAD_ACCESS”. (gdb) bt #0 0x335625fa in objc_msgSend () #1 0x32c04eba in CFDictionaryGetValue () #2 0x3016d500 in get_value () #3 0x3016d5d6 in CGPDFResourcesGetFont () #4 0x3015fbb4 in CGPDFContentStreamGetFont () #5 0x30163480 in op_Tf () #6 0x3016df12 in handle_xname () #7 0x3016dd9e in read_objects () #8 0x3016de6c in CGPDFScannerScan () #9 0x30161e34 in CGPDFDrawingContextDraw () #10 0x3016a9dc in CGContextDrawPDFPage () Is this an indication that I've mistakenly deallocated an object? It's hard for me to decode what's happening here. This is how I create and retain the various objects involved: // Some data was just loaded from the network and is pointed to by "data" self.pdfData = data; _dataProviderRef = CGDataProviderCreateWithData( NULL, [_pdfData bytes], [_pdfData length], NULL ); _documentRef = CGPDFDocumentCreateWithProvider(_dataProviderRef); _pageRef = CGPDFDocumentGetPage(_documentRef, 1); CGPDFPageRetain(_pageRef); _pdfFrame = CGPDFPageGetBoxRect(_pageRef, kCGPDFArtBox); So the NSData object is retained, and I explicitly retain the page reference. The data provider and the document are already retained by the create-functions. And here is my dealloc method: -(void)dealloc { if (_pageRef) CGPDFPageRelease(_pageRef); if (_documentRef) CGPDFDocumentRelease(_documentRef); if (_dataProviderRef) CGDataProviderRelease(_dataProviderRef); self.pdfData = nil; [super dealloc]; } Am I doing anything wrong? Even an assurance that I'm not, with explanation, would be a help.

  • android.intent.action.SCREEN_ON doesn't work as a receiver intent filter

    - by Jim Blackler
    I'm trying to get a BroadcastReceiver invoked when the screen is turned on. In my AndroidManifest.xml I have specified : <receiver android:name="IntentReceiver"> <intent-filter> <action android:name="android.intent.action.SCREEN_ON"></action> </intent-filter> </receiver> However it seems the receiver is never invoked (breakpoints don't fire, log statements ignored). I've swapped out SCREEN_ON for BOOT_COMPLETED for a test, and this does get invoked. This is in a 1.6 (SDK level 4) project. A Google Code Search revealed this, I downloaded the project and synced it, converted it to work with latest tools, but it too is not able to intercept that event. http://www.google.com/codesearch/p?hl=en#_8L9bayv7qE/trunk/phxandroid-intent-query/AndroidManifest.xml&q=android.intent.action.SCREEN_ON Is this perhaps no longer supported? Previously I have been able to intercept this event successfully with a call to Context.registerReceiver() like so registerReceiver(new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // ... } }, new IntentFilter(Intent.ACTION_SCREEN_ON)); However this was performed by a long-living Service. Following sage advice from CommonsWare I have elected to try to remove the long-living Service and use different techniques. But I still need to detect the screen off and on events.

  • Unable to load UIView with initWithNibName in Apple SDK 3.1.3

    - by James Foster
    I am trying to load my UIViewController and corresponding UIView programmatically in the AppDelegate class. I have the following in the applicationDidFinishLaunchingMethod of the AppDelegate class: (void)applicationDidFinishLaunching:(UIApplication *)application { NSLog(@"--- AppDelegate applicationDidFinishLaunching Start"); // Override point for customization after application launch //MainController *controller = [[MainController alloc] initWithNibName:@"MainView" bundle:nil]; MainController2 *controller = [[MainController2 alloc] initWithNibName:@"MainView2" bundle:nil]; if (controller.view == nil) { NSLog(@"--- controller view is nil!!!!!!"); } [window addSubview:controller.view]; [window makeKeyAndVisible]; NSLog(@"--- AppDelegate applicationDidFinishLaunching End"); } Basically the view in the viewController doesn't load and when the application launches, it just shows the blank window. What is funny is that it worked before and then just stopped working. I am wondering if this is a bug in iPhone SDK 3.1.3??? This is a really annoying issue, and I was quite a ways along in a new project when I started having this problem and had to start over with a blank project and copy over all of my resources, when it started happening again... I have uninstalled iPhone OS 3.1.3 and reinstalled and the problem prevails... I also created a second UIViewController class and corresponding nib which DOES LOAD just fine... I am not sure why one works and the other doesn't it... You can download a sample project which demonstrates this issue at the following link: http://www.mediafire.com/?nmhnmhbeyki To switch back and forth between the working/nonworking UIViewController and UIView simply comment comment/comment out the initWithNibLine lines in the AppDelegate and the corresponding #import "MainController.h" statements in the appdelegate.h file... Any ideas??? The sample project I have linked to isolates the problem in as few files/lines of code as possible... I appreciate any help you might be able to provide. Thanks, James
