writing *useful/professional* event logs with VB6 was a real PIA, I've lost
the count of how many times I've read LJ Jhonson article on the subject (on
VBPJ,
http://www.devx.com/premier/mgznarch/vbpj/2001/09sep01/lj0109/lj0109-1.asp)
and I still think it's a real nightmare.... VB6 App.LogEvent sucks... you
can't change the source fields (it's always VBRuntime) .... it doesn't work
while in the IDE.... and so on....

but .NET changes this... write event logs is real easy... so I was waiting
for the final release to install the framework on one of our Windows2000
servers to test this feature.....

I was able to comunicate VB6 Apps with a NET DLL (thanks to a Bipin Joshi
article, http://www.bipinjoshi.com/com/com_iop.asp?language=com&page=1),
this net dll has a class wich has method that writes events.... but what
I've not been able to find a method o property that let me set the User
field, the WriteEntry method of the EventLog class doesn't seem to use this
field... any ideas ?

thanks,

Rolando

Are you referring to the UserName property of the EventLogEntry class?

If so, this property is read-only and usually only appears in the
Security log.
When used, it's the SID of the user or group.

Unfortunately, in the .NET Framework the UserName property of the =
EventLogEntry class is Read-Only. I haven't confirmed this, but it looks =
like this property is only populated with the SID by the .NET Framework =
when writing to the Security log.

Hi Rob,thanks for taking the time to help me with my problem...

I'm talking about the User field/column of a logged event....
after logging an event using the EventLog.WriteEntry method, when I go =
to
the event viewer and see the event the "User" column.... it has this =
value
: "N/A"

but using the technique described by LJ Jhonson using the ReportEvent() =
API
it seems it's posible to set this field with a real username

"When you pass the SID to the ReportEvent() API, the user's name appears =
in
the event log record. All you need to do is open a process token for the
current process, then get the token information for the user running =
that
process. Normally, this is the user who last logged onto the machine.
However, you can run processes as, for example, LocalSystem (as in an NT
service), or the application's author can impersonate other users so =
that
process could return users besides the currently logged-on user."
