Hiding winforms app from taskbar

In code do the following:

this.ShowInTaskbar = false;

Or in Design mode:

EDIT:

You must also set the FormBorderStyle

Code:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.SizableToolWindow;

Design:

This definitely does work - these are some screen prints using Windows Vista.

App running:

Not appearing in ALT + TAB


To hide your form from the Alt+Tab dialog, add this code into your form's class:

// Remove from Alt+Tab dialog
protected override CreateParams CreateParams
{
    get
    {
        var Params = base.CreateParams;
        Params.ExStyle |= 0x80;
        return Params;
    }
}

    Check whether the form’s WindowState property is set to FormWindowState.Minimized. If yes, hide your form, enable the NotifyIcon object, and show the balloon tip that shows some information. Once the WindowState becomes FormWindowState.Normal, disable the NotifyIcon object by setting its Visible property to false.

    If you want to prevent a Win Form from both appearing in the TaskBar, and from appearing in the Alt-Tab switch-programs facility: C#. Copy Code. this .ShowInTaskbar = false ; this .FormBorderStyle = FormBorderStyle.FixedToolWindow; You could also use the 'SizableToolWindow option.

    Customize the System Tray Scroll down the Taskbar settings screen to the section for Notification Area. Click the Select which icons appear on the Taskbar link. You can then turn on the app icons that you wish to see in the System Tray and turn off the ones you want to stay hidden.
