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;
    }
}

In code do the following:

this.ShowInTaskbar = false;

Or in Design mode:

alt text

EDIT:

You must also set the FormBorderStyle

Code:

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

Design:

alt text

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

App running:

alt text

Not appearing in ALT + TAB

alt text
