Monitoring Double Click of a Folder

Hi there.

I am trying to make an app that launches a window(Form Window) whenever a user click a folder in Windows. My app will be running in the background all the time and it will be monitoring the double click of a particular folder.

I have found this

http://www.codeproject.com/KB/dotnet/folderwatcher.aspx

But the problem is that, it checks attributes of the folder instead of the double click.

Is there anyway i can check the double click of a folder in Windows?

anybody??
