Because you cannot use the DBError event with a Web Service DataWindow, you must use the WSError event to obtain any error information.
The following code in a WSError event script causes information about an error to display in a message box:
MessageBox("Error event", "Error in row " &
+ string(rownum) + ", Occurred during " + method &
+ "; the cause of the error is: "+ errormessage)
