To write a daily report on the enterprise wechat every day, a robot is added to remind you to write a daily report regularly, so a local service is made.
1, Create enterprise wechat robot
Click on the top right of the group to add a robot
The Webhook address above will be used in the next three steps
2, Create project
1.VS create a new project Windows service
2. Right click on the Service1 [design] interface to add the installer
The control as shown in the figure below appears
Click serviceInstaller1 to set the startup mode of the service and the service name displayed in the service list on the property panel
Click serviceProcessInstaller1 and set the service type to local mode in the property panel
OK, the creation of the project is completed, and the rest is to move the bricks
III. coding
1. Program. The Main method in CS is the starting point of the whole program, and can call multiple service programs. It is free to play here. The program we are currently writing will not be extended
2. Daily report service. In the service code, OnStart and OnStop are executed only once, at the start and stop time respectively. In addition, there are OnContinue, OnPause, etc. for details, press F12 at ServiceBase to retrieve metadata.

3. After the project is generated, the server can be deployed
4, Deploy local services
1. Find the generated project folder
2. Copy an installutil Exe to folder
3. Create a new notepad in the folder and edit it
cd /d "%~dp0"
InstallUtil.exe WindowsService1.exe
net start ReportService
cmd
4. Rename the new Notepad to install Bat for installing services
5. Create a new notepad and rename it uninstall Bat to uninstall the service
cd /d "%~dp0"
InstallUtil.exe /u WindowsService1.exe
cmd
6. Run install. As an administrator Bat, the service will be installed, which can be found in the service list. The service name is the service name ReportService named in step 2 just now
V VS debugging
Debugging additional processes in VS
Additional adjustable
6, After development and commissioning
1. Execute uninstall as an administrator Bat uninstalls the debugging service
2. You can copy the generated project folder to the place you want to put it, and then execute install as an administrator Bat can be used
