Remarks
COM Signature
From vsshell.idl:
HRESULT IVsWindowFrame::IsOnScreen(
[out, retval] BOOL *pfOnScreen
);
IVsWindowFrame.IsOnScreen checks to see if a window hosted by the Visual Studio IDE has been autohidden, or if the window is part of a tabbed display and currently obscured by another tab. IsOnScreen also checks to see whether the instance of the Visual Studio IDE is minimized or obscured.
IsOnScreen differs from the behavior of IsWindowVisible a method that may return true even if the window is completely obscured or minimized. IsOnScreen also differs from IsVisible which does not check to see if the Visual Studio IDE has autohidden the window, or if the window is tabbed and currently obscured by another window.
