How to set Win32 window as owner of WPF window?

Question

I want to use WPF windows in a legacy win32 application. I'd like to behave them in a similar way, like the WPF window always being displayed on top of the win32 window.

For this I'd like to set the owner of the WPF window to the win32 windows, but I got no idea how to achieve this.

Any help here?

Since the answer is hidden behind some link, here the code that did the trick:

System::Windows::Interop::WindowInteropHelper^ helper = gcnew System::Windows::Interop::WindowInteropHelper(myWpfChildWindow);
helper->Owner = (System::IntPtr)myMainWindowHWND;

Answer 1

How about SetParent()? I know works when making a WPF window an MDI Child of a Windows Form.

Answer 2

This article shows how to get the handles for both as well as how to make the WPF window become a transparent overlay for the win32 window.

This article uses a WindowInteropHelper to accomplish similar functionality.
