Re^2: Write to Win32 Event Log, get "/AUXSOURCE=" error

Awesome. This sounds quite right, though I haven't tested it yet, about to do it now. This is exactly the input I needed. Thanks, you rock.

While I ask a lot of Win32 questions, I hate Windows with a passion. That's the problem with writing a cross-platform program. I'm a Linux user myself. I wish more people were.

Re^3: Write to Win32 Event Log, get "/AUXSOURCE=" error
by wilsond (Scribe) on Jan 21, 2009 at 06:54 UTC

I don't want to use it, but in case it helps anyone, I found that in XP (and probably newer Windows versions), there is a binary in SYSTEM32 called eventcreate.exe that will write to the EventLog with a custom source name without the same error I've been getting. This is an example usage: eventcreate /ID 1 /L APPLICATION /SO MyAppName /T INFORMATION /D "This is a test entry in the EventLog."

And extending on the idea of using eventcreate.exe, you can use it in a different way: using it as the source of your EventLog messages in the registry. Here is what works for me (import into registry after modifying your app name:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Applica
+tion\MyAppName]
"EventMessageFile"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52
