need help declaring printdlgex types

[evalese]

Hello. I'm hoping someone can tell me why I'm getting error C2065: undeclared identifier when trying to declare LPPRINTDLGEX and other PRINTDLGEX types.

I am using Visual C++ 6 SP5, Nov 2001 SDK.
I've got the SDK include, lib, and bin directories at the top of the lists.
I've defined _WIN32_WINNT 0x0500 AND WINVER 0x0500
I've included <windows.h> and <commdlg.h>
I've even tried forcing the SDK comdlg32.lib file's path in the Object/Library settings.

This is on an XP and a 2000 machine using two separate and otherwise new projects.

Thanks for any help in this matter.

Ben
