Determine the location of a Windows taskbar button or thumbbar button?

Question

I have added some ThumbBar buttons via ITaskbarList3. Now when those are clicked I'd like to open the action / dialog next to the taskbar button. How can I find the screen coordinates of the taskbar button?

Thanks.

Use UIAutomation. Find your way to the bottom of the tree and retrieve UIA_BoundingRectanglePropertyId for each child element.

Powershells ShortcutGuide does this, you can look at their code if you need additional help...
