Introduction
When you create a Windows Service by deriving from System.ServiceProcess.ServiceBase, you can set various properties of the service, but not the value that gets displayed in the "Description" column of the "Computer Management" screen. This is how to set it by using the Windows API rather than mucking about in the registry.
How It's Done
The Windows API provides several methods for working with the Service Control Manager; these are documented here.
The source code included with this article does the following:
- Calls
OpenSCManager to connect to the service control manager
- Calls
OpenService to connect to the requested service
- Calls
ChangeServiceConfig2w to set the description (this is the Unicode version of the function)
- Calls
CloseServiceHandle to close the service and service control manager
Using the Code
Add the included file to your project.
In classes that derive from System.ServiceProcess.ServiceBase, add something like the following:
public void AfterInstallEventHandler
(object sender, System.Configuration.Install.InstallEventArgs e)
{
SetServiceDescription ( ServiceName , "This is my service" ) ;
}
In classes that derive from System.Configuration.Install.Installer, after instantiating each System.ServiceProcess.ServiceInstaller, add something like the following:
serviceInstaller.AfterInstall += new System.Configuration.Install.InstallEventHandler
( myservice.AfterInstallEventHandler ) ;
