Hi
I'm a newbee to windows graphic programming and i have bought a book called Windows game programming for dummies.
And it is really good, except for one little problem.
Some of the directx example files wont compile for me :(
Have tried both borland 5.02 and visual c++ 6.0.
The problem is the same each time in a number of diffrent files

\\c++\gpchap12\starferr.cpp(216) : error C2440: '=' : cannot convert from 'void *' to 'struct HBRUSH__ *'
Conversion from 'void*' to pointer to non-'void' requires an explicit cast
?? this line is giving me a bit of an hedace, what is wrong...
plz help me!

Thats because it has to be typecasted to type HBRUSH
Edit that line and make it (HBRUSH)GetStockObject(whatever_here);
Just add (HBRUSH) and nothing else, then compile.

Those are warnings because those 2(ps & hdc) are never used in the whole program. You don't have to worry about it. If its concerning you too much then you can comment the two.
