Calling RAS API functions without linking to DLL

Nulogic #1 / 3	Calling RAS API functions without linking to DLL Hello, I've got some code which calls the RasEnumConnections function from the RAS api, but I don't want to link to the DLL, so I used the method of getting the Module handle. Here is the code I am using: DWORD dwConnections; RASCONN rasconn; rasconn.dwSize = sizeof(RASCONN); DWORD dwSize = rasconn.dwSize; DWORD dwSuccess; typedef DWORD (WINAPI fp_RasEnunCons)(LPRASCONN lprasconn, LPDWORD lpcb, LPDWORD lpcConnections ); fp_RasEnunCons fncptr1 = NULL; HMODULE hModule = ::GetModuleHandle(TEXT("RASAPI32")); fncptr1 = (fp_RasEnunCons)::GetProcAddress(hModule, "RasEnumConnectionsA"); if (fncptr1 != NULL) { DWORD dwSuccess = (fncptr1)(&rasconn, &dwSize, &dwConnections); Quote: } else { Quote: } The Problem is, that fncptr1 ends up being NULL. Can someone please tell me what I am doing wrong. Thank you. Nulogica

Ian Semme #2 / 3	Calling RAS API functions without linking to DLL I may be misunderstanding your question, but if you #include <rash.h> and <raserror.h> and in the Linker options rasapi32.lib and tapi32.lib you can statically link rhe RAS functions.

Nulogic #3 / 3	Calling RAS API functions without linking to DLL Hi, The whole point is that I don't want to be dependant on the RAS dlls being installed on a system. If I link them, my program won't run without having the RAS dlls.
