Hi,
I'm learning Windows Programming with C++ and in the book I've got, one of the examples doesn't work. I was wondering if any experienced Windows/C++ programmer could tell me why not?

Thanx.

P.S. I e-mailed the publishers but no reply.

First of all, did you include <windows.h> at the top of your program? If so, check if your compiler needs any special parameters, like Borland command line tools needs -W (I think)

I would be unstoppable if I could just get started...

well there are far simpler interfaces that the WinAPI and the MFC interfaces ... GTK and WxWindows are very good examples
if you could show the example it might help to determine why it doesn't work.

Maybe you should have gotten Ivor Horton's Beginning Visual C++ 6 book. It shows quite a bit actually, comes with a demo for Microsoft Visual C++ (anything it compiles can only be run inside of itself, not from Windows Explorer or anything, which means no sharing your programs )


Dark Basic Pro has arived! I can feel the power!

Not a lot wrong there - just some casts missing (lines 65 and 66) and an extra argument provided to the LineTo function (line 68).

The fixed and working WndProc function is in the code button

Hmmm. It works Ok for me ...

Did you create a new 'Windows Application' project for the code? If not then that's what you need to do
