Thanks Mike, all I need to do now is learn how to use @try,@catch and @finally...
is there sample code on this?
Thx

After 6 or 7 times, TextEidt or the other App will crash.
I've seen something similar. I've also seen it with certain types of
email content--especially advertising with combined text and images.
The code where the error occurred looked something like this:
BOOL goodPBoard ;
NSPasteboard *pboard = [NSPasteboard generalPasteboard];
goodPBoard = [myTextView readSelectionFromPasteboard:pboard];
Originally, the error caused the routine containing this code to exit
prematurely, often causing a crash.
Now I use @try, @catch, and @finally to make sure the routine
containing these lines is completed.
Here are some actual examples of exceptions raised by various
pasteboard content as they appeared in the debugger:
*** NSRunStorage, _NSBlockNumberForIndex(): index (3980) beyond array
bounds (1000)
*** NSRunStorage, _NSBlockNumberForIndex(): index (152166) beyond array
bounds (2000)
*** NSRunStorage, _NSBlockNumberForIndex(): index (40555) beyond array
bounds (4000)
*** NSRunStorage, _NSBlockNumberForIndex(): index (4363) beyond array
bounds (3000)
The first one comes from going to
http://www.digitaleyes.net/Details.cfm?info=PIO012301 and copying
everything from "eX Driver The Movie" down to "Production Art" at the
end, then pasting it.
The interesting thing is that, in spite of the exception, the copied
material seems to paste in just fine. It doesn't appear to be
corrupted, displays okay, and can be saved.
I've wondered whether this qualifies as a bug in the
-readSelectionFromPasteboard routine.
