Microsoft is now pushing Active Accessibility (MSAA) for UI Automation, (It has been renamed a number of times over the years) see

• UI Automation and Microsoft Active Accessibility
• Using UI Automation for Automated Testing
• UI Automation Clients for Managed Code

Sorry I don’t have any simple code to get you started. As “SendMessage()” does not seem to be working for you, I don’t know of another option apart from “UI Automation”

I am assuming you have check with Spy++ (installed with MsDev) that you message are being send to the correct button etc – and that the button is a standard windows buttons. My first instant would say use “SendMessage()" or "PostMessage()” but given the numbers of answers about “SendMessage()” and the fact it is not working for you. I expect someone is going on…
