In Microsoft System Center Configuration Manager 2007, the site control file maintains configuration for the site. This topic shows how to enable or disable the Software Distribution Advertised Programs Client Agent setting in the site control file. Details about reading from and writing to the site control file are discussed in the Configuration Manager Site Control File section of the Configuration Manager SDK.

Warning

You should be experienced in managing a site's configuration before using the SMS Provider classes to modify the site configuration. You should use caution or avoid using the SMS_SCI_FileDefinition and SMS_SCI_SiteDefinition classes altogether. These classes manage the site control file itself. You can cause significant damage to a site by changing some configurable items.

To enable or disable the client agent

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Make a connection to the software distribution client component section of the site control file by using the SMS_SCI_ClientComp class.
Adjust the client agent settings by setting the flag value to 0 to disable the agent or 1 to enable the agent.
Commit the property changes to the site control file.

Example

The following example method queries for the specific site control file item, software distribution client component section, and changes the flag value to enable or disable the client agent.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Sub EnableDisableSWDClientAgent(swbemServices, swbemContext, enableDisableFlag, siteToChange )

    ' Load site control file and get SWD client component section.
    swbemServices.ExecMethod "SMS_SiteControlFile.Filetype=1,Sitecode=""" & siteToChange & """", "Refresh", , , swbemContext
    Set objSWbemInst = swbemServices.Get("SMS_SCI_ClientComp.Filetype=1,Itemtype='Client Component',Sitecode='" & siteToChange & "',ItemName='Software Distribution'", , swbemContext)
    
    ' Display SWD client agent settings before change
    Wscript.Echo " "
    Wscript.Echo "Properties - Before Change"
    Wscript.Echo "---------------------------"
    Wscript.Echo objSWbemInst.ClientComponentName
    Wscript.Echo objSWbemInst.Flags & " (0 = Disabled, 1 = Enabled)"
    
    ' Set SWD client agent by setting Flags value to  0 or 1 using the sEnableDisableFlag variable.
    objSWbemInst.Flags = enableDisableFlag
    
    ' Save new client agent settings.
    objSWbemInst.Put_ , swbemContext
    swbemServices.ExecMethod "SMS_SiteControlFile.Filetype=1,Sitecode=""" & siteToChange & """", "Commit", , , swbemContext
    
    ' Refresh in-memory copy of the site control file and get the DCM client component section.
    swbemServices.ExecMethod "SMS_SiteControlFile.Filetype=1,Sitecode=""" & siteToChange & """", "Refresh", , , swbemContext
    Set objSWbemInst = swbemServices.Get("SMS_SCI_ClientComp.Filetype=1,Itemtype='Client Component',Sitecode='" & siteToChange & "',ItemName='Software Distribution'", , swbemContext)
    
    ' Display SWD client agent settings after change.
    Wscript.Echo " "
    Wscript.Echo "Properties - After Change"
    Wscript.Echo "---------------------------"
    Wscript.Echo objSWbemInst.ClientComponentName
    Wscript.Echo objSWbemInst.Flags & " (0 = Disabled, 1 = Enabled)"
    
    ' Release copy of the site control file.
    swbemServices.Get("SMS_SiteControlFile").ReleaseSessionHandle swbemContext.Item("SessionHandle").Value

End Sub

public void EnableDisableSWDClientAgent(WqlConnectionManager connection, string enableDisableFlag, string siteCode)
{
    try
    {
        IResultObject siteDefinition = connection.GetInstance(@"SMS_SCI_ClientComp.FileType=1,ItemType='Client Component',SiteCode='" + siteCode + "',ItemName='Software Distribution'");

        // Display SWD client agent settings before change.
        Console.WriteLine();
        Console.WriteLine("Properties - Before Change");
        Console.WriteLine("---------------------------");
        Console.WriteLine(siteDefinition["ClientComponentName"].StringValue);
        Console.WriteLine(siteDefinition["Flags"].StringValue + " (0 = Disabled, 1 = Enabled)");

        // Set SWD client agent by setting "Flags" value to 0 or 1 using the enableDisableFlag variable.
        siteDefinition["Flags"].StringValue = enableDisableFlag;

        // Save the settings.
        siteDefinition.Put();

        // Verify change by reconnecting and getting the value again.
        IResultObject siteDefinition2 = connection.GetInstance(@"SMS_SCI_ClientComp.FileType=1,ItemType='Client Component',SiteCode='" + siteCode + "',ItemName='Software Distribution'");

        // Display SWD client agent settings after change.
        Console.WriteLine();
        Console.WriteLine("Properties - After Change");
        Console.WriteLine("--------------------------");
        Console.WriteLine(siteDefinition2["ClientComponentName"].StringValue);
        Console.WriteLine(siteDefinition2["Flags"].StringValue + " (0 = Disabled, 1 = Enabled)");
    }

    catch (SmsException ex)
    {
        Console.WriteLine("Failed. Error: " + ex.InnerException.Message);
        throw;
    }

}

The example method has the following parameters:

Parameter	Type	Description
connection swebemServices	Managed: WqlConnectionManager VBScript: SWbemServices	A valid connection to the SMS Provider.
swbemContext	VBScript: SWbemContext	A valid context object. For more information, see How to Add a Configuration Manager Context Qualifier by Using WMI.
enableDisableFlag	Managed: String VBScript: String	Flag to enable or disable the client agent.
