minimieren in den systemtray

[MathiasSimmack]

Ich schon. Ist aber keine saubere .NET-Lösung. Aber solange deine Programme nur auf Windows laufen sollen, mag´s gehen:

Code:

private const int WM_SIZE        = 0x0005;
private const int SIZE_MINIMIZED = 1;

protected override void WndProc(ref Message m)
{
   if(m.Msg == WM_SIZE && (int)m.WParam == SIZE_MINIMIZED) {
      notifyIcon1.Visible = true;
      this.ShowInTaskbar  = false;
   }

   base.WndProc(ref m);
}

void MainFormClosing(object sender, System.ComponentModel.CancelEventArgs e)
{
   notifyIcon1.Visible = false;
}

#region NotifyIcon
void MenuItem1Click(object sender, System.EventArgs e)
{
   if(this.WindowState == FormWindowState.Minimized)
      this.WindowState = FormWindowState.Normal;

   this.Activate();
   notifyIcon1.Visible = false;
   this.ShowInTaskbar  = true;
}
      
void MenuItem2Click(object sender, System.EventArgs e)
{
   this.Close();
}
#endregion
