about selection rectangle.

I would guess this is not the best way, but you could get a DC for the
screen and convert your form coordinates to SCREEN coords and then just API
directly to the screen :)

Hi,
    I'm writing a program to implement adding,deleting, moving and
resizing control on the form dynamically. so i need a selection tool to
select one control. when i draw a selection rectangle and the rectangle
intersect with a control, the rectangle will appear beneath the control.

    How can i draw a rectangle over all controls on my form but not to
hide them.

Re:about selection rectangle.


In the FormMouseMove draw a rectangle on the forms canvas.
Just guessing.
