Drawing in dialog box

i am a newbie and so have simple problem. i am using MFC in my app.

how could i draw on dialog box... i want to draw small rectangles in it and add functionality to them.
thanks

Handle WM_PAINT message.

what kind of functionality??

If you want to select objects and so on, you have to use a special draw object for this (as far as I know)... If you just want to draw them, you can use this code:

Code:

---

        CPaintDC dc(this); // device context for painting
        int x = 50, y = 50; // add your own coordinates here
        int iSize = 10;  // add the size you want

        brush.CreateSolidBrush(RGB(150, 50, 50)); // you own color here, this is red
        dc.SelectObject(brush);
        dc.Ellipse(x - iSize, y - iSize, x + iSize, y + iSize);
        brush.DeleteObject();

NOTE: Do not delete a drawing object (pen or brush) while it is still selected into a DC.
