isZoomed() functionality is not working in my client code

Question

i wanted to know whether mstsc(RDP) window maximized or not from my client application. so i\'m using :

IsZoomed(handle of mstsc); but i\'m always getting zero as return

Answer 1

IsZoomed detects whether the window is maximized in the WS_MAXIMIZED sense, which means that it has a caption bar with a maximize button. But fullscreen apps don't work that way, which is why IsZoomed always reports "It is not maximized with a caption bar." You will have to use some alternate detection mechanism, like looking at the window dimensions.
