Is there a way to programmatically remove a leftover notifyicon from some other program still showing in the tray?

Thank you for your fast response.
In my case, I'm purposely killing a process that creates what you’re calling a “rogue icon” left in the tray.
I found the following article and grabbed the code I need.
Again, thanks…

In older versions of Windows (pre-Windows 7), you could force the tray area to refresh/redraw to do this. But I am not sure it will still work on Windows 7.

Edit/Update
------------

This is in response to your comment. There are two cases where a rogue icon is left behind:

1) When the app exits without explicitly removing the icon. This now invalidates the icon handle. By forcing a refresh of the inner toolbar window, this icon will be auto-removed. You can see this if you move your mouse around the orphan icon.

2) The app crashes and goes into a zombie state without the process actually terminating. In this case there's not much you can do in a documented manner. But if you want to go the undocumented route, take a look at this article I wrote a few years ago:

It's not been tested on Windows 7 so I have no idea how that'll pan out on that OS.
