Closing Forms?

Hello,

My application works like a Wizard..so the user will have to click Next to display another Form and so on..

I want a way to close the application..So when the user clicks on "Close" (the X icon on the upper right side of the form) the form disappears but I want the application to continue working..until he closes the Main Menu Form..

Any help

thanks

You will need to make child forms... or atleast secondray forms.

Do you know how to do this?
