Yeah,I have loaded the dll and its returning 0x11000000 value in HINSTANCE But while getting the address of that function,its returning value 0x00000000. Whats the reason? If we open a dll in notepad, it should contain the function names right? but this is dll is not showing any fn names in notepad. Please tell me why GetProcAdress is returning NULL value? Thanks,
