Restore Windows

I have a window that is waiting for an event to occur. While waiting the
operator may minimize the window.
When the event occur I would like to restore the window and bring it into
focus. How can I do that programmtically?

Hi,
I have tested solution shown in below link is working perfectly well.Instead
of window.Handle you need to write yourminimizedform.Handle.

Thanks.
Now I have to try to translate the code to VB.

Take a look at the form's 'WindowState' property. In order to make your
application the active one, you'll have to use p/invoke with
'SetForegroundWindow' + 'AttachThreadInput'.

Note that changing the foreground window programmatically may cause
confusion for the user because the input (keyboard, mouse) will be directed
to another window immediately.

Herr Wagner,
Can you supply a code example for ideas, please?

This works great:
WindowState = FormWindowState.Normal

Thanks,
but that example does not compile. The code makes a call to
GetForegroundWindow(), which is not defined.
