This interface is implemented on objects that expose Win32 HWND handles. The resultant handle can be used with Win32 API calls.

The following example sets the Text property of label1 to the current Handle of Form1. This example assumes that you have a Form called Form1 with a Label called label1 on it.

public Form1()
{
   InitializeComponent();

   this.label1.Text = this.Handle.ToString();
