Re: Can't attach to process on CE device

Are you using the standard SDK or a custom SDK? Toolhelp.dll is part
of the kernel debugger, so if your SDK wasn't built with the "Enable
Kernel Debugger" option checked, you'll probably have problems trying
to use it. (Even if you manually included the file.)
On my emulator toolhelp.dll is present in the \windows directory, and
it isn't read-only. When I try to attach to a running process with eVC
I get a message about not being able to find commdlg.dll, but I can
cancel past it.
BTW, attach to running process is a better way to debug in eVC. I
wrote a post about it a little while back.

Hope part of my rambling helped,
Dan.
