How do i write the percentage sign "%" to the event log?

[K Viltersten]

It seems that when i try to write a
percentage sign (%) into the event log
using WriteEntry method, the log believes
that i'm refering to some variable from
command line.

Is it a special character when logging?
I've tried to Google it a while but i saw
nobody giving a suggestion for a
resolution.

I've made a workaround by
WriteEntry(mess age.Replace("%" ,"_"),...);
but it's not exactly a solution filling me
with pride.

No idea, but I presume you have tried both %% and \%?

I've tried "\%" and of course "\\%"
but it didn't work. Now that i've tried
the "%%" setup, i got DOUBLE percentage
signes! As one would expect, that is...

I'll go with this for now, unless someone
has a better idea. Thanks Peter!

Unfortunately, the docs for the unmanaged version of this API say:

Note that there is no way to log a string that contains %n,
where n is an integer value. This syntax is used in IPv6
addresses, so it is a problem to log an event message that
contains an IPv6 address. For example, if the message text
contains %1, the event viewer treats it as an insertion string.

You didn't post a code example so we don't really know what you're trying
to write to the event log, but I would guess that you're running into the
same limitation in .NET, because .NET is using the underlying unmanaged
API.

On the bright side, it does imply that as long as you don't follow the %
immediately with a digit, you'd be okay. So maybe you can put a space in
or something.

Yes, that's what i went with - i put double percentage
signs in there. It feels like a kindergarten solution; more
a walk-around than a solution, really. Still, provided the
infromation above (thanks for the link), i guess i'm
already at the best position. Thanks!

(As for the code, i don't think it'll help us a lot. I only want
to log the string "%1%2%3".)
