How to execute commands when an error occurs

1) Use the script from the previous undo tutorial

2) Disable the error dialog

Add this line to [Settings]:

BatchSettings.ErrorDialogDisable=Yes

3) Create the [OnError] section

a) Click file / new section / onerror to create an empty [OnError] section.

b) Fill the section with this code:

EventLog.Write Error, 770, SetupBatcher Error - %LastErrorCommand% - %LastErrorMsg%
SaveScript C:\Err_%date%%time%.cnu

4) Run the script twice

Run it twice to make sure that an error occurs - when the directories exists.

Notice that the error dialog is not displayed anymore.

5) Verify the result

a) Open the event viewer and check the application log:

b) Open explorer and go to c:\

A copy of the script has been saved as c:\Err_2002-08-25.cnu with all markers intact. This setup is very useful when a script is called automatically from the schedule service - when an error occurs it is possible to open the script that failed and retry it from where it stopped in GUI.
