Chang,
I prevent multiple launches of a form by disabling the button in the click, and the child form re-enables the button during it's Destroy.
>Anyone know how to prevent to display the same called form when issue a do form comment ?
>example, when i click a button to do a form, the form will diplay. and if i click again the button it will display the same form again that mean i have issue two same form already.I only want it to display one time even though the user click how many time on the button.
>How to prevent that ?
