>Hi,
> I have a MDI main form which have form menu to allow do form to call out another forms.
> I will call out a background form first(Maximize form to cover the main form) and then the call out form will display as the top of the background form.
> That means i will have 3 form now. When i close the call out form, it will close the background form too.
> But i face a problem is, when the 3 form is open, if i use Alt-Esc to switch the diplay form back to main MDI form, and i call out another function form, the form will display at the top of the main MDI form.
> Is it posible to lock the user to switch back to main MDI form when the call out form is display as the top of the background form?
> I did try to made the background form and the call out form to be Model, but the call out won't display, only the background form will display.
> Is that anyway to solve this problem ? thans
