Programming Windows® Services with Microsoft® Visual Basic® 2008

Using the WMI Class

In this chapter we will use our WMI class to extend the code in Chapter 3. We will use the code to collect information about the local system and log an event.

Adding New EventLog Constants

We will add the constants shown in Example 8-3 to the top of the modService.vb file so that we can write the correct EventID to the Application log.

Example 8-3. Application log EventID constants.

Public Const WMI_ERROR As Integer = 1010
Public Const WMI_INFO As Integer = 2007
Public Const CONFIG_READ_ERROR As Integer = 4000

Updating <Tutorials.ThreadFunc>
