Question:
I am trying to use the CreateProcessAsUser API function. If I put the declaration found in the win32api.txt, the program responds, “Can’t found DLL entry point” (Lib kernel32 function CreateProcessAsUserA).
Answer:
You didn’t give the declaration you are using, but the following should work:
