Hi all,
I am in the need of creating a harbour app as a service.
AFIK there are two ways to do that. One could be using a win32 tool to
convert a console app into a win32 service. The other is to do it
programmatically. I prefer second one.
Well, I found some code and samples that create and install a service.
Should be compiled
Hbmk2 std l{win}xhb test
The idea is :
- First service should be installed. This is done by uncommenting
call to SvcInstall function in STARTSERVICE. This is done by calling
from console to application.
- Second is to start service. This is done by Services. After
installing service you should find a new entry in services list. There you
can start/pause/stop this service.
Well
This code is very bad L. The idea of a service is to start in a
different entry point than standard main.
So
if someone can help to get this work Ill be very happy J
Regards,
José Luis Capel
