[execnet-dev] how to remotely open a program on win box?

[Mathieu Drapeau]

Hi Charles,
I don't think it is the makegateway call that causes problems, I did try
bunch of different configuration without any help...
But the "source" variable seems weird. The way I understand it, it should be
a string and I should be able to output in the logs but everytime I try to
print its value, I get an error like this:

"RegisterEventSource/ReportEvent", the parameter is incorrect

Here is how I am trying to output the value of source:

try:
    servicemanager.LogErrorMsg("source = %s" % source)
except Exception as e:
    servicemanager.LogErrorMsg("error = %s" % e)

Any idea?

Thanks,
Mathieu
