Is there a way within vb to find which window has focus on a computer? For instance if IE, Open Office Writer and Photoshop are open, how can I programmatically tell which one has focus?

This would need some code class to native window function, here is C# code you can port it to VB

using System;<br />using System.Windows.Forms;<br />using System.Runtime.InteropServices;<br /><br /><br />public class MyClass<br /><br />{<br />    [DllImport("user32.dll")]<br />    private static extern IntPtr GetForegroundWindow();<br />    [DllImport("user32.dll")]<br /><br />    public static void Main() {<br />        IntPtr handle = GetForegroundWindow();<br />    }<br />}
