After I searched for this for a while only to realize that I already have the answer in one of my utils classes I decided to put the answer on stackoverflow. Hopefully someone finds this useful.

Isn't SetParentconsidered "more correct" than SetWindowLongwith GWL_HWDPARENT(-8)?
是不是SetParent认为“更正确”比SetWindowLong用GWL_HWDPARENT（-8）？
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

Use this method:
使用这个方法：
[DllImport("user32.dll")]
private static extern int SetWindowLong(HandleRef hWnd, int nIndex, int dwNewLong);
/// <summary>
/// sets the owner of a System.Windows.Forms.Form to a System.Windows.Window
/// </summary>
/// <param name="form"></param>
/// <param name="owner"></param>
public static void SetOwner(System.Windows.Forms.Form form, System.Windows.Window owner)
{
WindowInteropHelper helper = new WindowInteropHelper(owner);
SetWindowLong(new HandleRef(form, form.Handle), -8, helper.Handle.ToInt32());
}
