An owner-draw control is one that you, the programmer and owner of the application, are responsible for drawing. For example, if you create a pushbutton, Windows will draw it for you. If you create a pushbutton and one of the styles is owner draw, you are responsible for writing the code that draws the button -- borders, text, background, everything. Windows will tell you when it needs to be drawn.

thankx for the help, that was exactly what i need to know.
