How to draw a resizable rectangle

Anybody could give me an idea about how to draw a resizable rectangle on a Dialog?. I mean, the kind of rectangle used to select a region of a Bitmap, that expands and contacts as you move the mouse. I have tried several aproaches with Rectange(), RectDot() and LineTo() but I am sure it must be a simpler way.
Thanks

Rafael,
You might look at the incomplete IDE samples that come with FW. I can't remember if there was such an thing for dialog design, but it is worth a look.

Thank you. I had erased long ago my FW folder. I have re-installed it and found the program you suggested. I'm going to take a long look at it.

Thank you for your suggestion. Problem solved. The trick -in case it can be of use to anybody esle- is to use bMMoved() and bLClicked() together with DrawFocusRect() and call this last function twice: The first to erase the previous rectangle, the second to draw it in a sligtly different place.
Best regards,
Rafael
