beginSheetForDirectory is an instance method, not a class method.
myPanel=[NSOpenPanel openPanel];
[myPanel beginSheetForDirectory:NSHomeDirectory()
file:nil
type:fileTypes
modalForWindow:myWindow
modalDelegate:self

Ok, I fixed it so that it matches what you've got..
Now, it still generates the same runtime thing, but, the warnings pb gives
me are different.

'myDelagate.m:15: warning: `NSPanel' does not respond to
`beginSheetForDirectory:file:type:modalForWindow:modalDelegate:didEndSelecto
r:contextInfo:'


myDelagate.m:23: warning: `NSPanel' does not respond to `filenames'


MyPanel should be an NSOpenPanel.

There's a lot of fishy stuff in your code, though.


- (IBAction)openPic:(NSWindow *)sender
{
NSArray *fileTypes = [NSArray arrayWithObjects: @"jpg", @"gif", @"tiff"
@"bmp", @"ping", @"pict", @"pdf", @"eps", nil]; // Fine
NSWindow *myWindow; // Bad! You need to attach that sheet to some existing window. What you're doing here can cause a crash.

[[NSOpenPanel openPanel] beginSheetForDirectory:NSHomeDirectory()
file:nil
type:fileTypes
modalForWindow:myWindow // Wrong! You need a pointer to an existing window.
modalDelegate:self
didEndSelector:@selector(openPanelDidEnd:returnCode:contextInfo:)
contextInfo:sender];
return FALSE;
}

- (void)openPanelDidEnd:(NSOpenPanel *)sheet returnCode:(int)returnCode
contextInfo:(void *)contextInfo{
{
NSArray *myArray;
if(returnCode == NSOKButton)
myArray = [sheet filenames]; // Don't use "myPanel", use sheet
}
}
