WPF: How to make a form's owner to be the calling app?

My WPF app is called by a C program (unmanaged). I want to make the WPF app stay on the screen where the calling app is. I have dual monitor.

So I want to make my WPF form WindowStartupLocation="CenterOwner" and set the owner to the calling app.

I can get the calling app via 

Process.GetProcessById(CallingProcessID)

What is the next step to set WPF window Owner to the calling app?

Update: The purpose of the question is to make WPF windows all stay on the screen where the calling program resides.

Assuming you have a window handle of your unmanaged application (HWND), you can use the WindowInteropHelper to set this HWND as your WPF window's parent.

WindowInteropHelper wih = new WindowInteropHelper(myWpfWindow);
wih.Owner = unmanagedOwnerHwnd;

The Owner property is of IntPtr type, so this should solve your issue.
