HI, I can't seem to find any documentation explaining what the OpCode field is in the events log. When an event is displayed the General tab has the following labeled fields: "Log Name", "Source", "Logged", "EventID", "Task Category", "Level", "Keywords", "User", "Computer", "OpCode", and "More Information". What is the Opcode field information and what do the values mean? I've seen "Info", "(0)", "(1)", and "(2)". Thanks in advance. - Neil ShoreNeil Shore

the opcode field is available since vista/w2k8 and as far is i understand the docu is task/event specific (http://msdn.microsoft.com/en-us/library/aa383974(v=vs.85).aspx). So my guess would be whoever generates an event is the one who knows what is ment by whatever he fills the property with

FZB, Thank you for your answer. I will have to do some reading about applications posing to the Windows Application events log. Any suggestions? - Neil Neil Shore
