ACCESSING METHOD EXPORT in CLASS in DLL

[Killer3]

Can i have a sample code that achieves it? class __declspec(dllexport) MyClass { public: static char* LSGDecrypt(const char* key,const char* hex); static char* LSGEncrypt(const char* key,const char* source); } The above class is export in a dll . So should i add new function to the dll ? Iam about access a static function So is that required to instantiate the class object. HINSTANCE hDLL; // Handle to DLL LPFNDLLFUNC1 lpfnDllFunc1; // Function pointer char* key = new char [50]; key ="KEYVAULE"; char* strPlain = new char [50]; strPlain="password"; char* strResult = new char [50]; DWORD dwrd =NULL; hDLL = LoadLibrary("Mydll.dll"); if (hDLL != NULL) { lpfnDllFunc1 = (LPFNDLLFUNC1)GetProcAddress(hDLL,"LSGEncrypt"); if (lpfnDllFunc1 ==NULL) // Fails here? so DLL is freed up? { FreeLibrary(hDLL); } else strResult = lpfnDllFunc1("killer" ,"strikes HERE"); } for thendral

You can use Exported class this way, because the function have no memory till the Classobject is created.this method is only used to load Dll function. for loading class from DLL, first you have to create MFC extention DLL,secondly you can try this article... http://www.codeproject.com/dll/noextensiondll.asp
