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

This appears to be exactly what you are asking for. I've never done it myself, but it appears to be relatively straightforward:

Creating a IWin32Window from a Win32 Handle

Good luck!

Answer 2

Control.FromHandle

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

Eg.

IntPtr myWindowHandle = new 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.
