need help for a simple mfc program

that means no solution to give mouse click control to a rectangle or an icon drawn in a view class.. I am not supposed to use dialogue based. So in OnDraw() i draw a bitmap then a rectangle over bitmap. then i attached an Icon to that rectangle. Now what i want is when ever some one clicks on the icon(rectangle area), a file should be opened..

You can handle WM_LBUTTONDOWN.
it gives you the coordinate of the last left-button click.
Just check if they are into the rectangle.
