# This is an example of a service hosted by python.exe rather than
|
||
|
|
# pythonservice.exe.
|
||
|
|
|
||
|
|
# Note that it is very rare that using python.exe is a better option
|
||
|
|
# than the default pythonservice.exe - the latter has better error handling
|
||
|
|
# so that if Python itself can't be initialized or there are very early
|
||
|
|
# import errors, you will get error details written to the event log. When
|
||
|
|
# using python.exe instead, you are forced to wait for the interpreter startup
|
||
|
|
# and imports to succeed before you are able to effectively setup your own
|
||
|
|
# error handling.
|
||
|
|
|
||
|
|
# So in short, please make sure you *really* want to do this, otherwise just
|
||
|
|
# stick with the default.
