Form.Hide

[bhavin]

Hi,
I need a application running on the PPC without any interface, like a
windows service. Is it possible in the CF?

Googling for it didn't really give me any relevant tips. So I thought of
creating a Form and the Hiding it in the constructor itself, and then
quietly keep doing what the application needs to do. Not too neat, but would
work I thought.

Wrong!
this.Hide() in the Application (Form) constructor doesnt seem to work for
some reason. Any thing special I need to do here?

If I try doing a this.Hide in a GotFocus event handler, it kind of works
(form dissapears but the main menu, with the keyboard control still shows).
also inside this eventhandler if I have a messagebox, the form doesnt
disappear. I am thinking there is something to do with the screen refresh
maybe.

I've attached the code of a test form I created.
really appreciate any help. on the Service issue, as well as Form hiding.

Why not choose a "command line application" as a project ttype? That creates
a windowless application. Of course you will need to do sometihng to prevent
it from quitting prematurely. Typically such app should wait for some event
and then kick in, do some work and go back to sleep

Simply don't create a Form in your Main. Don't use Application.Run, but
instead write some form of loop or whatever for your app construct.

I will try to do it that way. But any thoughts on why the Form.Hide behaves
such unexpectedly?
Is some part of the application or Screen not repainting itself right?
