隐藏通知图标上下文菜单的虚拟任务栏图标

Question

I have a simple .Net 5.0 WinForm form which is automatically hidden after the application started:

private void form_Shown (object sender, EventArgs e)
{
    Hide ();
}

It only creates a notify icon. This notify icon has a context menu strip that is shown by a left mouse click:

private void notifyIcon_Click (object sender, EventArgs e)
{
    contextMenuStrip.Show (MousePosition);
}

This works fine, but as long as the context menu strip is visible, a dummy taskbar icon appears:

This doesn't happen if the form is not hidden or the context menu strip is shown by a right mouse click (via ContextMenuStrip property).

How can I prevent this icon?

Answer 1

I finally found a solution myself:

[DllImport ("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
private static extern bool SetForegroundWindow (HandleRef hWnd);

private void notifyIcon_Click (object sender, EventArgs e)
{
    SetForegroundWindow (new HandleRef (notifyIcon.ContextMenuStrip, notifyIcon.ContextMenuStrip.Handle));
    notifyIcon.ContextMenuStrip.Show (MousePosition);
}

Answer 2

Try Me.Hide()

lets see the outcome

Try assign your context menu to the notifyicon s .ContextMenu property like and use the notifyicon s .Visible property to show it instead of using the .Show method.
