The following example shows how to modify a program, in Microsoft System Center Configuration Manager 2007, by using the SMS_Package Server WMI Class and SMS_Program Server WMI Class classes and properties.

Important

Any advertised program fails to run when the maintenance windows defined on the client computer are set for a period that is less than that program's Maximum allowed run time setting. See the topic "Program Run Scenario Using Maintenance Windows" in the Configuration Manager 2007 documentation for more information.

To change the maximum run time for a program

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Query for the programs associated with the existing package ID provided.
Enumerate through the programs until a match for the program name is found.
Replace the program maximum run time property with the one passed into the method.
Save the program object and properties.

Example

The following example method changes the maximum run time for an existing program.

Note

A slight variation of this example could change property values for all of the programs associated with a specific package. For an example, see the How to List All Programs and Their Maximum Run Time Value code example. However, for a more efficient method of accessing a specific program, using the PackageID and ProgramName, see the How to Modify Program Properties code example.

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

Sub ModifyProgram(connection, existingpackageID, existingProgramNameToModify, newMaxRunTime)
    
    ' Build a query to get the programs for the package. 
    query = "SELECT * FROM SMS_Program WHERE PackageID='" & existingPackageID & "'"
    
    ' Run the query.
    Set programsForPackage = connection.ExecQuery(query, , wbemFlagForwardOnly Or wbemFlagReturnImmediately)

    ' The query returns a collection that needs to be enumerated.
    For Each program In programsForPackage     
             
        ' If a match for the program name is found, make the change(s).
        If program.ProgramName=existingProgramNameToModify Then
        
             ' Replace the existing package property (in this case the package description).
             program.Duration = newMaxRunTime
             
             ' Save the program with the modified properties.
             program.Put_
    
             ' Output program name.
             wscript.echo "Modified program: "  & program.ProgramName
             
             Exit For
        End If
    Next

End Sub

public void ModifyProgram(WqlConnectionManager connection, string existingPackageID, string existingProgramNameToModify, int newMaxRunTime)
{
    
    try
    {
        // Build query to get the programs for the package.
        string query = "SELECT * FROM SMS_Program WHERE PackageID='" + existingPackageID + "'";

        // Load the specific program to change (programname is a key value and must be unique).
        IResultObject programsForPackage = connection.QueryProcessor.ExecuteQuery(query);
        
        // The query returns a collection that needs to be enumerated.
        foreach(IResultObject program in programsForPackage)     
        {
            // If a match for the program name is found, make the change(s).
            if (program["ProgramName"].StringValue == existingProgramNameToModify)
            {                    
                 // Replace the existing package property (in this case the package description).
                 program["Duration"].IntegerValue = newMaxRunTime;
                 
                 // Save the program with the modified properties.
                 program.Put();
        
                 // Output program name.
                 Console.WriteLine("Modified program: "  + program["ProgramName"].StringValue);
            }
        }
                 
        
    }

    catch (SmsException ex)
    {
        Console.WriteLine("Failed to modify the program. Error: " + ex.Message);
        throw;
    }
}

The example method has the following parameters:

Parameter	Type	Description
connection swbemServices	Managed: WqlConnectionManager VBScript: SWbemServices	A valid connection to the SMS Provider.
existingPackageID	Managed: String VBScript: String	The ID of an existing package with which to associate the program.
existingProgramNameToModify	Managed: String VBScript: String	The name for the program to modify.
newMaxRunTime	Managed: Integer VBScript: Integer	New approximate duration, in minutes, of program execution on the client computer.
