Find the exe name when loading dll
-
I'm trying to debug a problem where multiple applications (exe's) are loading a common dll. I have some debug output in the InitInstance() and ExitInstance() of the dll's CWinApp class. I'd really like to know which app is loading/unloading for each line of debug output (I'm writing lines to a file) but have not found a way to do this. The m_pszExeName and m_pszAppName variables are always the name of the dll - so that's no help. The m_lpCmdLine is always blank so that's no help either. Is there a way to do this?

I don't know if that is feasible, it depends on the complexity of your project, but you could add the executable's name as an extra variable to some key calls to the dll and have the executables just provide their name to the dll for logging/debugging purposes.

This is not possible to found from the dll itself. Dll's are loaded (mapped in process address space) by the loader, so there could be a place to found which process load the dll. But I can't provide more help for you, my knowledge is limited to what I said.

Bummer. Unfortunately, not all of the app's that call my dll are written by my company. I guess I can add something to detect my app but the rest will have to remain unidentified. Thanks anyway.

Even though MFC's
DllMain()is calling your app'sInitInstance()method, can you not useGetProcess()orGetProcessId()?
