Below is the code in vbscript. The problem is, GetObject, startService, and ExecuteQuery commands may get errors because of various reasons. For example, after issuing "stopService" command, the state of the service may become "stopping", instead of "stopped", and the script is hanging there for quite some time. Sometimes, error messages such as "RPC is vbscript error handling best practices not available" was returned. Seems there is no catch exception machanism built into vbscript. Most of the examples I saw online never considered such situation. Does anybody know there is a good way to catch such kind of errors, and force these command (note: not service itself) to abort?

does not: On Error Resume Next strWMIQuery = "SELECT Name FROM Win32_Service2222" Set colListOfServices = objWMIService.ExecQuery(strWMIQuery) If Err.Number = 0 Then Any ideas why? Even "To Err http://stackoverflow.com/questions/5413591/how-to-catch-wmi-errors Is VBScript – Part 1" does not explain why this is the case... Larry Larry Tuesday, March 12, 2013 8:57 PM Reply | Quote Answers 0 Sign in to vote Strangely, the following code block allows for error checking: On Error Resume Next Dim objWMIService, strWMIQuery, colListOfServices Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2") strWMIQuery = "Win32_Service2.Name='gogo'" Set colListOfServices = objWMIService.Get(strWMIQuery) WScript.Echo "Error Number: https://social.technet.microsoft.com/Forums/scriptcenter/en-US/7cdc6cbd-0d75-4251-a3a0-e27f4497bcfa/error-checking-after-execquery?forum=ITCG " & Err.Number If Err.Number <> 0 Then WScript.Echo "Error with WMI query: " & strWMIQuery Else If colListOfServices.Count > 0 Then WScript.Echo "Found " & CStr(colListOfServices.Count) & " instances of 'gogo'."
