Graphics problem...

[Lee Garrington]

Hey there,

I am quite new to C++ and am having a couple of problems with the graphics.
So far the way I have been repainting the whole window is by forcing a
WM_PAINT of the whole thing. To do little updates of the screen I have used
GetDC and ReleaseDC however I am still having problems.
When I have loaded the program up if I minimise it and restore it 3 or 4
times the repainting of the window messes up. It only happens noticibly on
large windows so I have come to the conclusion that its some kind of memory
leak but I have done what the book I referred to said.

Can anyone help me out?

Thx

Lee

What you are talking about is not C++, but some obscure graphical operating
system.

You need to ask in a newsgroup dedicated to MS-Windows.
The FAQ contains some suggestions.
