c++ cli - Convert an IntPtr window handle to IWin32Window^

Question

How do I convert a handle acquired from a form/control's Handle property, to a IWin32Window^ ?

Answer 1

Control.FromHandle

(That gets you the Control object, which implements the IWin32Window interface.)

Eg.

IntPtr myWindowHandle = IntPtr(someVal);
IWin32Window^ w = Control::FromHandle(myWindowHandle);

Note that this relies on the handle being "acquired from a form/control's Handle property." You cannot use this technique with an arbitrary Win32 window handle.
