I'm looking for a way to prevent a user from moving the mouse outside a specific region during a drag operation. NODEFAULT in a mousemove() event does not prevent the mouse from moving.

I'm aware that there is a Windows API to set the mouse clipping region ...

I'm wondering if there's not a simpler way to accomplish this using native VFP capabilities?

Thanks,
