>The preprocessor run only once, before compiling the source code. Since the preprocessor can't see inside the macro, it cannot replace constants like wdWindowStateMaximize. Which mean that you will receive an error message at run time, since wdWindowStateMaximize doesn't say anything to the called method. It expect a numeric value.

He may also declare the constants used as local numeric variables, by inserting the necessary parts of the .h file and instead of

#define wzWhatever 0

putting

wzWhatever=0

Then the macros should work-
