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 ContextMenuStri p (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 contextmenustri p using either:
contextMenuStri p1.Show(this,
this.PointToCli ent(Cursor.Posi tion));
or:
contextMenuStri p1.Show(this.Po intToClient(Cur sor.Position));

This works well and displays the contextmenustri p 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.

RE: ContextMenuStri p from a left click on a Notify Icon

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
ContextMenuStri p.

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 ContextMenuStri p.

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

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

RE: ContextMenuStri p from a left click on a Notify Icon

Hi Linda,
Many thanks for your response. Unfortunately I am already using the
ContextMenuStri p 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

RE: ContextMenuStri p from a left click on a Notify Icon

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 SetForgroundWin dow before showing its
ContextMenu. To get this behavior, the user would have to do the same and
p/invoke SetForegroundWi ndow in the notifyIcon1_Cli ck EventHandler:

using System.Runtime. InteropServices ;

[DllImport("User 32.dll", ExactSpelling = true, CharSet = CharSet.Auto)]
public static extern bool SetForegroundWi ndow(HandleRef hWnd);

void notifyIcon1_Cli ck(object sender, EventArgs e)
{
SetForegroundWi ndow(new HandleRef(this, this.Handle));

this.contextMen uStrip1.Show(th is, this.PointToCli ent(Cursor.Posi tion));
}

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.
