LoadLibrary() error code 127

Question

I\'m having trouble with LoadLibrary() and getting an error that doesn\'t make sense to me:

   ::SetLastError(0);

   m_hDll = ::LoadLibrary(szName);

   if          


        

Answer 1

I would suggest using Dependency Walker to find out which method is missing or what DLLs are required or missing.

Answer 2

Ok, here is my solution: we had a complex dependency system and among them there were two DLLs with the same name (i.e. server.dll), but located on different paths.

When client.dll was loaded with LOAD_WITH_ALTERED_SEARCH_PATH, it seems, that windows wasn't able to figure out which one of server.dll should be used in symbols resolution (both server.dll were successfully loaded, of course).

The solution was quite easy: let the loaded dlls have unique names, i.e server-1.dll and server-2.dll.

Answer 3

I was getting the same error code after calling LoadLibrary(). Finally found through dependency walker that some dependencies of module (szName) were missing.
