问题 Hello guys: I've loaded my DLL in my project but whenever I use the GetProcAddress function. it returns NULL! what should I do? I use this function ( double GetNumber(double x) ) in "MYDLL.dll" Here is a code which I used: typedef double (*LPGETNUMBER)(double Nbr); HINSTANCE hDLL = NULL; LPGETNUMBER lpGetNumber; hDLL = LoadLibrary(L"MYDLL.DLL"); lpGetNumber = (LPGETNUMBER)GetProcAddress((HMODULE)hDLL, "GetNumber"); 回答1: Checking return codes and calling GetLastError() will set you free. You

问题 What's the best way for loading a dll from a dll ? My problem is I can't load a dll on process_attach, and I cannot load the dll from the main program, because I don't control the main program source. And therefore I cannot call a non-dllmain function, too. 回答1: After all the debate that went on in the comments, I think that it's better to summarize my positions in a "real" answer. First of all, it's still not clear why you need to load a dll in DllMain with LoadLibrary. This is definitely a

I'm using the 'LoadLibrary' from the Windows API, when I run the application, it throws me an error code 126. I read that it may be caused by dependencies, I checked what's wrong with some applications like Dependency Walker, but everything was fine. LoadLibrary in the application: HMODULE dll_mod = LoadLibrary(L"path_to_dll"); if(dll_mod==NULL){ std::stringstream error; error << "Could not load plugin located at:\n" << file_full.toStdString() << "\n" << "Error Code: " << GetLastError(); FreeLibrary(dll_mod); return error.str(); } Plugin code: #include "stdafx.h" #define DLL_EXPORT #define

Load 32bit DLL library in 64bit application

Is there a way to load a 32bit DLL library (something with the same usage as LoadLibrary) I would like to use that function along with GetProcAddress. I looked at WOW, but it does not seem to offer the functionality. The functionality should exist, since tools like DependencyWalker are able to read the symbols of a 32bit dll even though its 64bits. thanks John Knoeller Sorry, but you can only load a 32bit DLL into a 64 bit process when you are loading the dll as a datafile. You can't execute the code. http://support.microsoft.com/kb/282423 Microsoft recommends that you use interprocess COM to
