Run Windows Services on a remote computer

Recently I wrote a small program that runs on a remote server. However, when the system logs out the current login user, the program started by the user also stops. I checked a lot of information, it is not ideal to try to modify the registry and so on. simply do not be lazy. You can honestly write it as a Windows service. The procedure for creating a simple Windows service is as follows:

(1) create a Windows Service Project, right-click on the design page, and select add installer after the menu appears. A new page is displayed, with the controls serviceprocessinstaller1 and serviceinstaller1. In serviceprocessinstaller1, change the attribute account to LocalSystem, and change the attribute parent in serviceinstaller1 to serviceprocessinstaller1, the servicename attribute is the service name after the service is generated (for example, MSG ).

(2). After modifying the properties of this control. Return to the background of the new service page and add your own code:

(3 ). after the code is written, generate the file, find the generated EXE file under the project directory, and copy the file to the f disk. run cmd to enter the following directory: cd c:/Windows/Microsoft. net/framework/v2.0.50727, install this service: installutil F:/servicetest.exe. (The method to uninstall the service is installutil F:/servicetest.exe-U ).

(4) After the service is installed, start the service net start MSG (MSG is the service name), and a simple service is completed. The following code is provided:

 

Using system;
Using system. Collections. Generic;
Using system. componentmodel;
Using system. Data;
Using system. diagnostics;
Using system. serviceprocess;
Using system. text;
Using system. runtime. interopservices;
Using system. IO;

// Start the service
