[AD] Where to put variable

Posted 12 January 2011 - 06:54 AM

I want to connect to my active directory i found this code from this site: http://www.codeproje...vedirquery.aspx

My domain is name : xxxxx.xxx.xx
The problem is where to put active directory name?

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.DirectoryServices;
using System.IO;

namespace ActiveDirQuery

		private GroupBox	groupBox1;
		private CheckBox	UsersCB, ComputersCB, PrintersCB;
		private Label		FilterLabel1, FilterLabel2, FilterLabel3;

		// query filters for fetching the objects
		private TextBox		UsersFilter, ComputersFilter, PrintersFilter;

		// state of the query

have you tried running this code yet?
does it do anything?

from what I can gather from skimming over it, it seems to start with the active directory that you are connected to and sprawls out from there.
