Error_proc_not_found
::LoadLibrary(szName); if (m_hDll == NULL) // Failure to load the DLL. { DWORD err = GetLastError(); } The error is 127 ("The specified procedure could not be found.") 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 '09 at error_proc_not_found loadlibrary 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 import library, or .lib file

Windows Desktop Development > General Windows Desktop Development Issues Question 0 Sign in to vote Hi, I am wanting to use a function in Project A that is declared in a DLL defined by Porject B. The function in Porject B is: header: __declspec(dllexport) int __cdecl GetPageSource(LPCWSTR,std::string); implementation: int GetPageSource(LPCWSTR szURL,std::string location){ //code... return 1; } using dependency walker on the DLL created from ProjectB, I can see that the function seems to be exported as I am expecting. However, in Project A (where I want to use the function), the following code throws errors: HINSTANCE hGetProcIDDLL = LoadLibrary(L"C:\\Users\\a\\Documents\\Visual Studio 2012\\Projects\\GetPagSource\\Debug\\GetPagSource.dll"); FARPROC lpfnGetProcessID = GetProcAddress(HMODULE (hGetProcIDDLL),"GetPageSource"); std::cout << GetLastError() << std::endl; typedef int (__
