Example

The following example shows how to use Microsoft Visual Basic Scripting Edition (VBScript) to delete run histories from the server with a run end date that is earlier than, or equal to, March 31, 2003 (UTC).

Visual Basic Script  Copy Code 
Dim Service
Dim ManagementAgent
Dim DeleteDate

Set Service = GetObject("winmgmts:\root\MicrosoftIdentityIntegrationServer")
Set Server = Service.Get("MIIS_Server.Name='MIIS_Server1'")

DeleteDate = "2003-03-31"

WScript.Echo "Deleting Run Histories from " & DeleteDate

WScript.Echo "Result: " & Server.ClearRuns(DeleteDate)

The following example shows how to delete the run histories that have a run end date that is earlier than or equal to the time 13:25:00.000 on March 31, 2003 (UTC).

Visual Basic Script  Copy Code 
Dim Service
Dim ManagementAgent
