ContextMenuStrip from a left click on a Notify Icon

[=?Utf-8?B?cHJvZ2dlcg==?=]

I've written an application that can minimize to the tray and can reappear if
you double click on the icon in the tray (ShowInTaskbar is set to false).
I've also created a ContextMenuStrip (Visual C# 2005) so that you can write
click on the icon in the tray for options. I then captured the event for
mouse clicks on the Notify Icon so that I could detect the left click event
and then display the contextmenustrip using either:
contextMenuStrip1.Show(this,
this.PointToClient(Cursor.Position));
or:
contextMenuStrip1.Show(this.PointToClient(Cursor.P osition));

This works well and displays the contextmenustrip appropriately, however
whilst doing this it also creates an icon for the application in the taskbar
which isn't intended as the form has been set to ShowInTaskbar = false. I've
also tried using a dummy control as the parameter to show to no avail.

Hi Simon,

I performed a test based on your description and did see the problem.

I also performed a test on ContextMenu and found that the problem doesn't
exist on ContextMeu. So it looks to me like a limitation of
ContextMenuStrip.

I have searched in our inner database. However, I didn't find a similar
issue in it.

As for a workaround, I think you have two options.

One option is to use ContextMenu intead of ContextMenuStrip.

The other is to set the ContextMenuStrip property of the NotifyIcon to the
ContextMenuStrip on your form. Thus, you could show up the ContextMenuStrip
by right-clicking the NotifyIcon in the system tray.

Hope this helps.
If you have any question, please feel free to let me know.

Hi Linda,
Many thanks for your response. Unfortunately I am already using the
ContextMenuStrip property of the Notify Icon but as you state this only works
for right clicks and not also for left clicks hence the addtional code I
spoke of.

Do you know if there are any plans for Microsoft to fix this bug or do you
know if there are any other work arounds? If I remember correctly, by using
just ContextMenu instead you don't get the Office 2003 style menus.

Thanks

Hi Simon,

I received a response from our product team. The following is the response
I received.

The reason it works as a ContextMenu and not when Show is just called is
that the NotifyIcon p/invokes SetForgroundWindow before showing its
ContextMenu. To get this behavior, the user would have to do the same and
p/invoke SetForegroundWindow in the notifyIcon1_Click EventHandler:

using System.Runtime.InteropServices;

[DllImport("User32.dll", ExactSpelling = true, CharSet = CharSet.Auto)]
public static extern bool SetForegroundWindow(HandleRef hWnd);

void notifyIcon1_Click(object sender, EventArgs e)
{
SetForegroundWindow(new HandleRef(this, this.Handle));

this.contextMenuStrip1.Show(this, this.PointToClient(Cursor.Position));
}

I have tested the above code on my machine and confirmed it works.
If you have any question, please feel free to let me know.
