I understand that in VB .NET within your sub main() to start a form you must
do the following.

Application.Run(new frmMain())

or have your startup form as the start up object within the properties.

My question is

When you are finished with this form can you destroy and open a new form???
I am trying to open a new form a close this form and the whole application
closes. Do I have to hide this form and open and close forms??

Thanks,

Tristan.

Application.Run creates a message pump to passed form, if you close it to
display a new one , windows messages will be sent to a window that no longer
exists that's why your app shuts down, to fix, just hide main form instaed
of closing it.
