I've scoured usenet trying to find out how to make an app run in kiosk
mode.

From what I've seen the following should produce my desired result,
that is remove the taskbar and start menu from the app, but it only
removes the start menu. I've spent a half day playing with this code
to no avail, could someone use this to make a test CF app and see
what's wrong here? Or a working sample, but keep in mind I culled
this from supposedly working samples...

Thanks. - Beau

All you should need to do is remove the MainMenu control
from the applications main form. Then in the form load
event:

this.WindowState = FormWindowState.Maximized;

This will give you a full screen mode....

Thanks for the response.

I've seen mentions of this and had tried it but it did not work for me.
Then again I did not play with the MainMenu

I've created a bare bones app, removed the MainMenu (which I actually
need), and set this problem. Still nothing, both the taskbar and
mainmenu remain. I should probably mention I'm using I'm using PPC 2002
w/ VS.NET 2003.

Could you post a program which literally works that I could cut and
paste?

For this test this is all have in InitializeComponent -

private void InitializeComponent()
{
this.WindowState = FormWindowState.Maximized;
this.Text = "Form1";
}
 
Got it. I had to use MoveWindow to reposition the window over the
taskbar - which indeed had been moved to the background.
