Try this.Hide in form activated event.

C#

 private void Form1_Activated(object sender, EventArgs e)
        {
            this.Hide();
        }

//This code initialize method
private void InitializeComponent()
{
 this.Activated += new System.EventHandler(this.Form1_Activated);
}

Reason for my vote of one: You do realize that the Form.Activated event is triggered every time the form gets the focus? For example, if you unhide the form, it will give an Activated event. If you switch back to the form after using a different application (or even a different form or message box in the same application)

So every time the user tries to use the form, it will hide itself from him again... :doh:

Solution 2

Why?
If you don't want your application visible, then don't show a form at all - but that's kinda unusual, and you might be better writing a service instead.

You can't Hide the form in the Load event anyway, because the Show instruction is given after the Load event is completed - so it would hide what hasn;t been shown, and the display it anyway.

Why do you want to do this? Hiding a form is normally pretty odd - there may be a better way to do what you are trying to achieve.

the thing is I saved A previous state if it is set hide in previous state than on the start form this previous state value chaeck and according to it , it will hide

And one more thing the form will again show on pressing the shortcut key

OriginalGriff 7-Apr-14 5:53am

What shortcut key? A form can't get keyboard input while it's hidden...

OriginalGriff 7-Apr-14 5:53am

OK - set the default state to Minimized, then handle the Shown event.
You can call either the Hide or set
WindowState = FormWindowState.Normal;
in that and it will work fine.
(If you don't start minimized, then the form and all it's controls will "flash" into existence on the screen and then disappear)

OriginalGriff 7-Apr-14 6:10am

if (myConditionSaysHideTheForm)
{
Hide();
}
else
{
WindowState = FormWindowState.Normal;
}

this doesn't hide. Hide function not working on page load I guess also this.hide()

OriginalGriff 7-Apr-14 6:40am

And did you put that in the Form.Shown event handler? Or hid you ignore that bit and put it in the Form.Load which I explained won't ever work?

binadi007 7-Apr-14 6:48am

oh sorry I forget it initially that that code be placed in Form.Shown event handler.
Yeah Its Working perfectly
Thanku Once Again
