From: Joseph M. Newcomer on 19 Mar 2010 11:48 YOu have not actually said what you expected and what you got. THis is very important. Generally, the "text" of an event log record is obtained from the MessageTable associated with the application that registered the message. All that is stored in the even log is the "variable text" for the message, usually a word or two. ReadEventLog fills in an EventLogRecord which contains the event source and the event ID. You will have to use the registered event source to locate the EXE or DLL that holds the MessageTable, and LoadLibrary and FormatMessage to get the rest of the text. If you are not doing this, then you should not expect to see the "text" of the message. That's what the Event Viewer does to display the information.
