That doesn't make any sense to me on a call to LoadLibrary(). I haven't called GetProcaddress() yet. The DLL (and the application) are both compiled with VS++ 2005 SP1. What could be going wrong? visual-c++ loadlibrary share|improve this question edited Jun 27 '09 at 17:28 asked Jun 27 http://stackoverflow.com/questions/1053180/loadlibrary-error-code-127 '09 at 16:52 Adam Tegen 11.5k2392135 Maybe there's no DllMain in the library? Should it fail ::LoadLibrary? –Janusz Lenar Mar 17 '10 at 17:21 If DllMain sets 'last error' as 127 and then returns FALSE, will 'last error' be overwritten by the system before returning from ::LoadLibrary? –Janusz Lenar Mar 17 '10 at 17:25 add a comment| 8 Answers 8 active oldest votes up vote 16 down vote Let's take this step by step: The error message means that the dll was found but a required function is missing. (Jitter is right.) This implies that you have the dll you need, but not the right version. (Davefiddes is right, although the problem can be any dll, not just the Microsoft runtime library. And, at least for major updates, Microsoft gives its runtime libraries different names, so in that case it wouldn't be an issue.) This doesn't make sense, because no function has been requested from the dll being loaded. (Adam is right.) Therefore, the missing function was expected to be found not in the dll which is being explicitly loaded by the LoadLibrary command, but in a dependent dll which is being implicitly loaded at the same time, because the first dll requires it. (Zebrabox was close.) A dependent dll is a dll that is "statically" linked to the library being explicitly loaded, via an Forum Visual C++ & C++ Programming Visual C++ Programming Error 127 on a getProcAddress call If this http://forums.codeguru.com/showthread.php?478450-Error-127-on-a-getProcAddress-call is your first visit, be sure to check out the FAQ by clicking the link above.

I´ve created a DLL called bloq_mouse.dll. To create this DLL I wrote an bloq_mouse.h defining the functions to be exportable: #define DLLEXPORT __declspec(dllexport) std::vector< std:air< POINT , POINT > > coords; DLLEXPORT int loadBloqCoords(const char config[_MAX_PATH]); DLLEXPORT LRESULT CALLBACK mouseHookProc(int nCode, WPARAM wParam, LPARAM lParam); I also created an .def file : LIBRARY bloq_mouse EXPORTS loadBloqCoords mouseHookProc And then, in a separate project, I´ve created an executable with this code: hinstDLL = LoadLibraryA("bloq_mouse.dll"); if( hinstDLL == NULL ) { //send error message } FARPROC lpfnGetProcess = GetProcAddress(hinstDLL, "loadBloqCoords"); if(lpfnGetProcess == NULL ) { //send error message } The DLL seems to load succesfully (I copied it in the executable´s project dir) but when I try to access loadBloqCoords function I get an 127 error (cannot find the proccess). I´m new with DLL making and accessing, Can Anyone Help Me? Thanks. Reply With Quote June 5th, 2009,08:28 AM #2 Paul McKenzie View Profile View Forum Posts Elite Member Power Poster Join D
