C++ -- GUI Hang Stack Trace -- Help Needed

[Saad]

Hi,

I have an application written in VC6 which we have ported to VS 2005
with old syntax. Earlier this app had gui based on unmanaged code, now
in addition to that we also have some .Net GUI in it. Now I have
following queries related to this app:-

1) Sometimes the GUI hangs in release mode. Now during this hanged
time i would like to somehow get the call stack of the gui thread to
see where the thread is stuck? Is it possible to do that in c++?

2) When the application crashes, i would like to get the call stack of
the crash. Currently since the backend code is in unmanaged c++, im
unable to get the call stack. How can i get call stack info in c++?
Dump Files??

Thanks in advance for the replies.

There is no way.

Dump Files??

If you don't care about files, dump them, of course.

Your question seems to be specific to Microsoft Visual C++ or Windows
GUI programming. If that's so, please consider posting in their
respective newsgroups. The list of the suggested newsgroups is in the FAQ.

Debugger is your tool. Use it. Usually any running application can be
suspended (paused) by the debugger, and when the thread is stopped, they
usually can show you the call stack. It has nothing to do with C++,
however.
