The following example shows how to set the distribute on demand flag property of an existing package by using the SMS_Package Server WMI Class class in Microsoft System Center Configuration Manager 2007.

To set the distribute on demand flag

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Load the existing package object by using SMS_Package Server WMI Class class.
Populate the package flag property.
Save the package and the new package properties.

Example

The following example method sets the distribute on demand flag for a package.

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

Sub SetDistributeOnDemandFlag(connection,         _
                              existingPackageID)
    
    ' Define a constant with the hexadecimal value for the DISTRIBUTE_ON_DEMAND. 
    DISTRIBUTE_ON_DEMAND = &H40000000

    ' Get the specific package instance to modify. 
    Set packageToModify = connection.Get("SMS_Package.PackageID='" & existingpackageID & "'")
    
    ' List the existing property values.
    Wscript.Echo " "
    Wscript.Echo "Values before change: "
    Wscript.Echo "--------------------- "
    Wscript.Echo "Package Name:            " & packageToModify.Name
    Wscript.Echo "Package Flags (integer): " & packageToModify.PkgFlags
    
    ' Set the new property value.
    packageToModify.PkgFlags = packageToModify.PkgFlags OR DISTRIBUTE_ON_DEMAND
    
    ' Save the package.
    packageToModify.Put_ 
    
    ' Output the new property values.
    Wscript.Echo " "
    Wscript.Echo "Values after change:  "
    Wscript.Echo "--------------------- "
    Wscript.Echo "Package Name:             " & packageToModify.Name
    Wscript.Echo "Package Flags (integer):  " & packageToModify.PkgFlags

End Sub

public void SetDistributeOnDemandFlag(WqlConnectionManager connection,
                                      string existingPackageID)
{
    // Define a constant with the hexadecimal value for DISTRIBUTE_ON_DEMAND. 
    const Int32 DISTRIBUTE_ON_DEMAND = 0x40000000;

    try
    {
        // Get the specific package instance to modify. 
        IResultObject packageToModify = connection.GetInstance(@"SMS_Package.PackageID='" + existingPackageID + "'");

        // List the existing property values.
        Console.WriteLine();
        Console.WriteLine("Values before change:");
        Console.WriteLine("_____________________");
        Console.WriteLine("Package Name:            " + packageToModify["Name"].StringValue);
        Console.WriteLine("Package Flags (integer): " + packageToModify["PkgFlags"].IntegerValue);

        // Modify the PkgFlags value to include the DISTRIBUTE_ON_DEMAND value.
        packageToModify["PkgFlags"].IntegerValue = packageToModify["PkgFlags"].IntegerValue | DISTRIBUTE_ON_DEMAND;

        // Save the package with the new value.
        packageToModify.Put();

        // Reload the package to verify the change.
        packageToModify.Get();

        // List the existing (modified) property values.
        Console.WriteLine();
        Console.WriteLine("Values after change:");
        Console.WriteLine("_____________________");
        Console.WriteLine("Package Name:            " + packageToModify["Name"].StringValue);
        Console.WriteLine("Package Flags (integer): " + packageToModify["PkgFlags"].IntegerValue);
    }
    catch (SmsException ex)
    {
        Console.WriteLine("Failed to modify package. Error: " + ex.Message);
        throw;
    }
}

The example method has the following parameters:

Parameter	Type	Description
