Detecting Dialogs from other application

[Guest]

I have some C# code that runs via the VSAEngine under a host program. There
is a situation where the host program will display a dialog that will stop
execution of my code. There is no API available to me to prevent this.

Is there a way by either looking at windows messages or a hook, that I could
detect when this dialog is displayed? Once I detect it, I know how to send it
keystrokes so that it will dismiss.

I haven't done any C/C++ windows programming, so if there is a way, I would
appreciate some pointers.

You should be able to use SetWindowsHookEx to do this. You could see if you
can catch window creation message in the same process and check if its the
same dialog as you expect by enumerating its childer, or looking at its
caption etc.

Using a hook in .Net is shown here:
