dumb question...

[Need Help]

This might be an extremely dumb question; I'm new to Visual C++, and am trying to use the simple Spooler API, OpenPrinter, but when I try to compile my source file, it says OpenPrinter is an undeclared identifier. Here's how I'm trying to use it

HANDLE newPrinter = NULL
BOOL op = OpenPrinter(ps09, &newPrinter, NULL)

Now, as far as I'm concerned there should be nothing wrong with that code, but does anyone else know what might be the problem? I'm using Visual C++ 6.0 on Windows XP. Thanks

Did you #include <windows.h>?

-cd

Yes, windows.h was included. There isn't anything other than that I
should have to include to get OpenPrinter, right?

Nope. The following compiles:

// Code
#include <Windows.h>

int main()
{
HANDLE hPrinter;
OpenPrinter("",&hPrinter,NULL);
}
// End of code

Exactly what error(s) are you getting?

-cd

Here's the error I got
error C2065: 'OpenPrinter' : undeclared identifie

My boss suggested it might have something to do with the fact that I'm not an administrator on the machine, and that perhaps this API tries to do something with the registry that I don't have access to. He's going compiling it on his and see if it works there. Thanks

No, the compiler knows nothing about who is and isn't an administrator, so
that can't be it (which doesn't mean that it won't work on your boss'
machine).

Can you post a complete example that doesn't compile for you? (Something
small - not your entire app. Frequently attempting to make a small program
that reproduces the problem will lead you to discover what's really wrong).

-cd

It turned it just some goofy pre-compiled header that Visual C++ adds in for you. I got rid of it and now it works fine. Thanks for your help!
