Application.run issue

I have an application that I do NOT want the form to be visible as this is a
background application. I set the forms Visible property to false in the
forms constructor. The application places an icon in the System Tray that
has a menu to show the form if the user wishes to see it. I'm displaying
the form by calling Application.Run ( form ). This forces the form to be
visible. I overrode the OnVisibleChanged event in the form and it is called
immedialely after the Application.Run call.

Does anyone know a way to keep the form hidden?

Thanks in advance

Hi Ken,
Have you considered starting the app from a Public Sub
Main routine that is located in a Module? From that point
you can instantiate the form and not show it. You can
reference its properties, etc.

Just out of curiosity, what type of app are you trying to
start this app from? Is it VB.Net app or c# app or ?

Why do you use a form? Why not simply call 'Application.Run' without parameters?
 
Hi Ken,
You may try this way:
1. set the WindowState to minimized;
2. Set ShowInTaskBar to false;
3. handle the corresponding events such as some context menu commands and
the double-
click on the notifyicon. Note you should also check the WindowState
property, since setting
Visible to true will take no effect on a minimized window with
ShowInTaskBar set to false.
here is a simple snippet,
<code>
private void notifyIcon1_DoubleClick(object sender, System.EventArgs e)
{
Visible = ! Visible;
if(Visible)
{
if(WindowState == FormWindowState.Minimized)
WindowState = FormWindowState.Normal;
}
}
</code>
Does this answer your question?
Please let me know, if you still have problems on it.
Thanks!
