A first chance exception of type 'System.NullReferenceException' occurred in DMS.exe

also...

here is the rest of what I saw in the Debug window.

It means something tried to work with an object that had not been created. Is that your program?

Jim

DMS.exe is my program.  What object are you talking about?

Wow!  I never knew I could break on all exceptions!  That alone will save me.

Thanks,

That's a great feature. I turn it on for every project and never turn it off.

Jim

Did you find the problem?

I won't be compiling to the AM.  I'm running a process now through the night.

I'll let you know...

newbieweb

I'm trying this but can't find the feature.

I see two checkboxes:
Thrown, User-Handles

for each of C++ Exceptions
CLR Exceptions
Managed Debugging Assistants
Native Run-Time Checks
Win32 Exceptions

and inside of each there are many items, a few of which have "Thrown" checked

Should I go ahead and check everything as Thrown?

Correct.
