I do not know if this helps, but Visual C++ comes with Depends that will tell you what you application depends on. There is also an add on that you can get (may be open source) called BeSweet. You can also use Doxygen to genterate documentation for your project, I beleive it will show all the dependencies in your project (read the article on Doxygen at codeproject). INTP

Having read the thread, I think the answer is simpler. There's a qualifying comment that says mapping the file for the current EXE always returns 4. I suspect that this is 'true' because the EXE is already mapped to address 00400000, and it's just something happening to obfuscate the value returned, or there's some shifting/misreading going on. In other words, the code is committing suicide in a fancy way by unmapping itself from memory while it's executing. The CPU pipeline cache may then probably prevent a page fault while it terminates.

Only a guess here, but the third arguement of PostMessage( UINT message, WPARAM wParam = 0, LPARAM lParam = 0); is designed for additional message information, you may need to send something else than the default 0.
