Recently, at the customer's requirement, a scheduled monitoring of Windows ServicesProgramTo enable the Service at random and regularly monitor the specified service. If the service is not enabled, it is enabled. Due to the rush of time, the server has not been running for a long time.CodeReleased, and will be updated in time for future improvements:
I. Ideas:
The core of this program is random start and Windows service. For random start, Microsoft. in the Win32 namespace, registrykey can be used to add, delete, and modify the Registry. For Windows Services, system is introduced. serviceprocess namespace. You can use the servicecontroller class to start, stop, and query system services. The program stability and resource consumption rate will be tested in another day.
II. The Code is as follows. Here, the program enables the MSSQLServer service by default and adds the tray area icon, which can be minimized to the tray area at startup or after startup: [Copy to clipboard] Code:
