i am building a personal program, i found this code on another site as it does exactly what i want and i work by the fact why reinvent the wheel :)

However what i cant figure out is how can i get it so that when the PC name is clicked it will load all that pc's shared folders etc in the windows explorer.
So basically what i want to do is when a pc is double clicked it will load the network browser window in windows for that pc which lists its shared stuff.

unless anyone knows of any better code than whats below.

i call it like so
Me.lbAPIComputers.DataSource = SearchNetwork.APINetworkItems.GetAllComputersInDomain
using a list box

VB.NET:
Imports System.DirectoryServices
Imports System.Runtime.InteropServices
