How do I stop the user from double-clicking the title bar of the MDIform and changing it to restore mode.

I have Used some API's (Copied it from somewhere - my knowledge of API's = NILL) to disable the restore/max button of the MDI form.

I open the MDI form in VbMaximised mode and want it that it shd remain either MAXimised or minismised but NOT in the "restored"
position.
