How to get handle (hWnd) in WPF (not WinForm)

Question

I'm looking for getting window handle of a WPF control (known as hWnd in Win32).

In WinForm. we can get by "core.Init(panel1.Handle.ToInt32());"

but it is impossible to do this in WPF.

//C# in WinForm panel1.Handle.ToInt32();

//C# in WPF???????????

Answer 1

Only the window in WPF maps to a HWND.

All other element types (such as the panel) are not HWNDs internally, so you cannot get a HWND for them.

One possible solution for you would be to use a WindowsFormsHost for the part of the application you need the HWND for.

Answer 2

You can access to Window handler by using WindowsInteropHelper class like this:

IntPtr windowHandle = new WindowInteropHelper(sampleWindow).EnsureHandle();

EnsureHandle() method description:

Creates the HWND of the window if the HWND has not been created yet.
