You enumerate the software updates, in Microsoft System Center Configuration Manager 2007, by creating an instance of the CCMUpdatesDeployment COM class and by using the EnumerateUpdates method. This example enumerates all updates that are deployed and available in the client UI.

To enumerate software updates

Create a CCMUpdatesDeployment instance by using the CCMUpdatesDeployment COM class.
Enumerate the updates by using the using the EnumerateUpdates method.

Example

The following example method shows how to enumerate the software updates by creating an instance of the CCMUpdatesDeployment COM class and using the EnumerateUpdates method.

Note

This example enumerates all software updates that are available in the client UI, both optional and mandatory.

In the example, the LocaleID property is hard-coded to English (U.S.). If you need the locale for non-U.S. installations, you can get it from the SMS_Identification Server WMI ClassLocaleID property or use the LocaleID value from the Configuration Manager Context Qualifiers.

Compiling the Code

This C# example requires:

Namespaces

System

System.Runtime.InteropServices

UPDATESDEPLOYMENTLib COM Automation Library

COM Automation

The reference that is needed for early binding is UpdatesDeploymentAgent 1.0 Type Library. This creates a type library reference named UPDATESDEPLOYMENTLib. The early binding object name for the Control Panel Manager is CCMUpdatesDeploymentClass.
