Setting category / event ID when tracing in VS2008

[=?Utf-8?B?dGhlYXJ0aXN0c3RpbGxrbm93bmFzZ2Fydmlu?=]

I am using an EventTraceListener to display certain significant events in a
VS2008 console app that runs on a server. I am able to write
"Trace.TraceError" messages, as well as information and warning messages,
along with my message text.

However, I cannot figure out how to the category and event ID, for display
in Event Viewer. Currently category = none, Event_ID = 0.

Hi Tommy,

To learn how to specify category for the event log entry, we need to first
learn some background on how event log works. I will leave the details to
MSDN (http://msdn2.microsoft.com/en-us/lib...2(VS.85).aspx). Some
key quoted content:

Message Files (Windows)
(http://msdn2.microsoft.com/en-us/library/aa363669.aspx)
<blockquote>
Each event source should register message files that contain description
strings for each event identifier, event category, and parameter. Register
these files in the EventMessageFile, CategoryMessageFile, and
ParameterMessageFile registry values for the event source.
</blockquote>

Here our focus is on the CategoryMessageFile, which is a message text file
(http://msdn2.microsoft.com/en-us/lib...46(VS.85).aspx) to define
our category. For example, save following content (including the 4th line
with only a dot) in a file (for example: cats.mc):

MessageId=0x1
Language=English
MyCategory1

Hi Tommy,

I just found out that my last reply was truncated, sorry about that. Here's

I understand now.

I was thinking that I could specify the category prior to, or concurrent
with, raising the Trace event.

I see from the referenced article that the category is looked-up from a
message file provided by the developer, which certainly makes sense, and also
allows for alternate language support.

Case closed!

(albeit with some more up-front work on the developer's part)
