How to start/stop and Enum Services using ADSI

This post will show you sample code in VB6 to use ADSI to manage services.

Step-By-Step Example

• Create a new standard exe project
• Add reference to “Active Ds Type Library” (Project->Add Reference)
• Add windows common control 6.0 (Project->Controls)
• Add one listview, five command button and one textbox control on the form
• Add the following code in form1

Option Explicit
