I'm doing Surface Automation of an application. The Automation is asynchron. Sometimes, a Dialog window occures and locks the mainwindow for further Access.
I'm using C++ / Win32API, C# or VB. I can get the main window by the processID and want to find (or write) a function, giving me true or false if the main window is locked by an unexpected Dialog window.
Modal windows disable their owner windows. So you need to call IsWindowEnabled on the main window.
