You had to use some system level procedure that was not very easy, but thanks to VB. NET this has become very easy. We shall now learn how to create a Windows Service. You should know a few things before we dive in. Windows Service is not available in Windows 9. ME. You need to have Windows NT or Windows 2. Services. The advantage to using. NET is that the framework incorporates all the classes. This shall help us to create, install, and control Windows Service. Open your Visual Studio. NET, create a new Windows Service Project, which we shall call My. Service, and then click OK. Add the Timer control from the Toolbar in the Components tab. In the properties window of Timer.

Our application is now ready, but a few things still need to be done before we move ahead. When we build this application, the executable created is not a Windows application hence, you cant just click and run it. It needs to be installed as a service but dont worry we dont have to do it manually. VB. Net has a facility to add an installer to our program and then use a utility to install the service. Adding Installer to the Project. Open the Service. Add Installer option. This adds an installer project, Project. Installer. vb, with two controls, Service. Process. Installer. Service. Installer. Select the Service. Installer. 1 control and open the property window. Change the Service. Name and Display. Name properties to My. Service. This is the name you want to appear in the list of services in Services windows. Select the Service. Process. Installer. Change the Account property to Local. System. This needs to be specified because we need to run this on our local machine. Now it time to build the application and create an executable. Select Build Solution from the Build menu to create an executable with installation instructions for the service. Installing the Service. To install this service, we need to use the Install. Util program, which is a. NET utility, to install Windows Service. You can find this in folder C WINNTMicrosoft. NETFrameworkv. 1. This might be different on your computer, depending upon the version you are using. Alternatively, you could run the. NET Command Window by selecting Start, Programs, Microsoft Visual Studio. NET, Visual Studio. NET Tools, Visual Studio. NET Command Prompt. This sets all the required paths for you. Type the following command in that window Install. Util C tgolMyserviceBinMyservice. This is the path for the executable of the service we just created. Remember, VB. NET created the executable in the Bin Folder under the project folder. Please make sure you change this to your executable path. Please look at the message and log to make sure the service is installed properly. Starting the Service. Running a service and starting a service are two different things. When we install the service with Install. Util, we are now running the service but have yet to start it. To view and start the service, open the Control Panel. Open Administrative Tools, click Services, locate My. Service, and right click and select Start to start this service. Now our service has started. Open the Event Viewer from Administrative Tools and click the Application Log to see the logs created by the Service My. Service every 1. If you dont see any logs, click Refresh F5. You will have to keep refreshing to see the latest event logs. Stopping the Service. Open Control Panel, open Administrative Tools, click Services, right click My. Service, and select Stop to stop the service. Uninstalling the Service. This procedure is similar to installing the service, but now we shall run the Install. Util with U Parameter, which uninstalls the service Install. Util U C tgolMyserviceBinMyservice. Please look at the message to confirm that the service is uninstalled properly. Tips. Stop the service and close the Service window before you installuninstall the service. Always uninstallinstall if you make any changes to the service application. Try avoiding user interface, inputs, and msgbox in the Service Application. Open Project. Installer. Service. Installer.
