    Question How To use CDC::DrawDragRect func.

    1) I read the help of this function, but I didn't find an example for it...

    2) you Know that we use this function to draw a "virtual" rectandle while we moving the mouse befor free it. Ok, what the alternative function if I want to draw "virtual Ellepse or line" ?

    1. Modify this for use with mfc:

    Microsoft Knowledge Base Article - Q135865 HOWTO: Use Win32 API to Draw a Dragging Rectangle on Screen DC

    2. Use modified code from 1. but use 'Ellipse' fn instead of Rectangle fn. Both Rectangle and Ellipse are CDC fns.
