Minimize on Formclosing event

[daimous]

hi! how can I hide the form and show a Taskbar icon instead when I click the Close button in the ControlBox. Thanks in advance!

// Indicates whether the form should be minimised rather than closed.
private bool hideOnClose = true;

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if (this.hideOnClose)
    {
        // Don't close the form.
        e.Cancel = true;

        // Minimise the form.
        this.WindowState = FormWindowState.Minimized;
    }
}

private void Form1_Resize(object sender, EventArgs e)
{
    bool minimised = this.WindowState == FormWindowState.Minimized;

    // If the form is minimised show only the tray icon, otherwise show the form but not the tray icon.
    this.ShowInTaskbar = !minimised;
    this.Visible = !minimised;
    this.notifyIcon1.Visible = minimised;
}

protected override void WndProc(ref Message m)
{
    // You need to change the 0x0 to the value for the message that is received when Windows is shutting down.
    if (m.Msg == 0x0)
    {
        // Windows is shutting down so you must allow the form to close.
        this.hideOnClose = false;
    }

    base.WndProc(ref m);
}

I don't know the value of the Windows message received when Windows is shutting down but I do know that it has been posted in the C# and/or VB.NET forum before, and probably the VB and API forums too. I'll leave it up to you to track it down, either here or elsewhere on the Web.
