Create a windows service

[leandro]

Buenos días para todos,

Tim buenos días como estas?, estuve consultando el foro como crear un servicio de windows y todo los caminos conducen hacia ti, jejejejeje.
De casualidad me puedes indicar el camino a seguir para lograr crear el servicio, y si de casualidad tienes un ejemplo te lo agradecería, de antemano gracias.

Good morning Tim, how are you? I was consulting the forum on how to create a windows service and all roads lead to you, hehehehehe.
By chance can you tell me the way to follow to create the service, and if by chance you have an example I would appreciate it, thanks in advance.

Here is the structure that I use. All commands go in the area noted /*. */

Remember, you DO NOT use any screen calls or operations ( or at least not in my experience ).

Tim, muchas gracias por la respuesta, nuestro amigo Cristóbal tambien nos envió el mismo código, pero el problema es que no funciona con xharbour, solo con harbour

In the past I used xHarbour Builder ( many years ago ). I have not used the current xHarbour.

Perhaps you could install Harbour and build your service with it. Several functions in here are necessary for my build but you might not need them. For example, ADS functions.
