Anyone knows how to access the property window of a file?

Thanks for replying.

Have two questions. What is "OwnerhWnd&" use for?

Sorry, to mislead you. I want to get the location of executable in the property window. Not show the property window.

Here is how to retrieve the exe's file path from the given handle:
