问题:

I'm having a weird problem with my program. I'm developing a windows form application. When I debug it through Visual Studio (F5) it works perfectly correctly, but when I run its executable it crashes and gives me "An unhandled exception of type 'System.ObjectDisposedException' occurred in mscorlib.dll".

I tried to put a top level (on my outermost function) try/catch for catching this exception, but still the program crashes. What am I missing here?

I didn't upload the code because I had to upload the whole code for you to see where the problem is.

Wow, an ObjectDisposedException that isn't caught by a top-level catch block?

I'm not sure what I would do in this case - obviously, you want to see the stack trace and find out just what it is that was disposed. There are a few un-catch-able exceptions, but this one isn't one of them. I'd probably attach a handler to the AppDomain.UnhandledException event, and see if that found anything.

If you can get the stack trace of the exception, it should help you debug the root cause. You may find the Call Stack window helpful for this. Check out the instructions here:

How to: Use the Call Stack Window.

You may also want to disable the "Just My Code" option for debugging in Visual Studio. This may give you better exception debugging information. Follow the instructions (to disable) here:
