how do u allow user to "draw" in SDK

[Tim Zorn]

how do u create a dc over ur whole dialog window and allow a user to draw lines on it? help would be appreciated thx:)

Override the CDialog::OnPaint() Unless you really mean the WHOLE window in which case use GetWindowDC() It's frustrating being a genius and living the life of a moron!!!

ok, thx. now how do u allow the user to draw on it?

You could create a custom control that handled the drawing and then insert the control in the dialog. To enable drawing you need to handle mouse messages (button down, mouse move, button up, etc.) and draw in the window accordingly. You can look at Microsoft's scribble sample program to get ideas on how to do it. There are Win32 and .NET versions for this sample, and although they are intended as MFC tutorials, you can still use it to extract useful ideas. -- jlr http://jlamas.blogspot.com/[^]
