I'd highly suggest going the UIAutomation route. You create an AutomationElement by window handle. Crawl to the button and invoke it. I'd just like to know how you managed to get the keyboard input working. I am currently trying to resolve the converse issue. How to get a WPF window (I've managed to get a hWnd to it via Win32 calls), to respond to virtual keyboard messages.

Here is an article explaining the whole business. The sample code is unfortunately in VB but I'm sure that won't stop you.

Use UI Automation to do this - trying to manually simulate input via window messages is a textbook mistake, like trying to start a land war against Russia.
