I’m writing a window spy type thing to add a feature to an application

  • 0

I’m writing a window spy type thing to add a feature to an application I have. I’ve got all the code working, but sometimes WindowFromPoint returns a handle for a control instead of the containing window. For my purposes, I am only concerned with the main containing window. Is there a way for me exclude controls? Or possible detect that the result is a control and recurse upward until I reach the containing window?

    You can test for the WS_CHILD flag (GetWindowLongPtr with ‘GWL_STYLE’) and if it’s there call GetAncestor with ‘GA_ROOT’ as ‘gaFlags’.
