hi scott,

i tried

hModule = LoadLibrary(L"ginafull.dll");
FARPROC a = GetProcAddress(hModule, "FYPLoggedOutSAS");
a(1);

<< but the compiler said

error C2197: 'FARPROC' : too many arguments for call

GetProcAddress is not a call to your function. It gets a pointer to
your function. Then you can use the pointer to call:

a(450);
