I tried Using C# Code in Vista gadget as you mentioned in your blog, below is the Wrapper class which i created for User32.dll

using System;
using System.Runtime.InteropServices;

namespace CheckDesktop
{
[ComVisible(true)]
public class CheckWindow
{
[DllImport("user32.dll", EntryPoint = "GetDesktopWindow", SetLastError = true)]
public static extern IntPtr GetDesktopWindow();

[DllImport("user32.dll", EntryPoint = "GetForegroundWindow", SetLastError = true)]
public static extern IntPtr GetForegroundWindow();

}
}

And i created the ActiveX object for using this in gadget Javascript as follows:

var wrapper;
wrapper = new ActiveXObject(“CheckDesktop.CheckWindow”);

Also I have registered the CheckDesktop DLL, but my code goes in exception when the ActiveXObject is created and i am not able to resolve it as i am not getting any Error Description, i am getting just an error code.

Please help,
Thanks,
Shreyas
