Drawing in a dialog box

[mr_mombob]

I'm trying to draw a graph on a dialog box for a numerical solution program I'm writing. I can draw on an SDI window, but I can't figure out how to draw on a dialog box, and it's driving me nuts. I'm using VC++ 6. Thanks

Are you using MFC?

In WinAPI it's pretty much the same as with a normal window. You just handle the WM_PAINT message in the DialogProc. You can then get a hDC with BeginPaint

I am using MFC. If there's a better way to do it, I'm all ears. Thanks

use OnPaint method in your derived class from CDialog to do this.
OK.
