Go WPF methods for implementing MDI Forms

(The effect is not very good, for reference only)

First: Create a new class win32native, introducing the Win32 external function.

The code is as follows:

public class Win32native
{
[System.Runtime.InteropServices.DllImport ("user32.dll", EntryPoint = "SetParent")]
public extern static IntPtr SetParent (IntPtr childptr, IntPtr parentptr);
}

Second: Create a new two form:

Window1.xaml

Window2.xaml

Third: Add references in Window1.xaml.cs

Using System.Windows.Interop;

IV: Put a Button1 in the Window1 form

The events are as follows:

private void Button1_Click (object sender, RoutedEventArgs e)
{
Window2 W2 = new Window2 ();
W2. Show ();

Windowinterophelper parenthelper = new Windowinterophelper (this);
Windowinterophelper childhelper = new Windowinterophelper (w2);

Win32native.setparent (Childhelper.handle, Parenthelper.handle);
}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

WinForms implementation method is simpler,

private void Button1_Click (object sender, RoutedEventArgs e)
{
Window2 W2 = new Window2 ();
W2. MdiParent = this;
W2. Show ();
