Service Tutorial 1 (C#) - Creating a Service. Writing an application using Decentralized Software Services (DSS) is a simple matter of orchestrating the input and output between a set of services. Services represent the interface to software or hardware and allow you to communicate between processes that perform specific functions. This tutorial is provided in the C# language. You can find the project files for this tutorial at the following location under the Microsoft Robotics Developer Studio installation folder: Sample location. Samples\Service. Tutorials\Tutorial. CSharp. This tutorial teaches you how to: Prerequisites. Hardware. This tutorial requires no special hardware. Software. This tutorial is designed for use with Microsoft Visual C#. You can use: Microsoft Visual C# Express Edition. Microsoft Visual Studio Standard, Professional, or Team Edition. You will also need Microsoft Internet Explorer or another conventional web browser. Application as Service for business Application as Service can be used to run Windows program as service in a. Application as Service for home use Run application. Step 1: Create a Service. Begin by creating a new service. Open the Start menu and choose the DSS Command Prompt command. If the command does not appear in the Start menu, choose All Programs, Microsoft Robotics Developer Studio, and then DSS Command Prompt. This opens a special Command Prompt window in the root directory of the installation path. Change to the Samples directory and run the Dss. New. Service tool using the parameters shown in the sample below to create your first service. Then change to the Service. Tutorial. 1 (Service. Tutorial< Number One> ) directory. This procedure automatically creates a template to help you get started. Run Windows Service as a console program. This is where your Service is Run. Can a C# windows service access a COMPORT and.

If your OnStart and OnStop methods run long, your service can request more time by. Consolecd Samples. Robotics /service: Service. The.Net Framework is an environment that permits.Net programs to run. C# is just one of many programming languages supported by the. Compile your first C# program. When you need to make configuration. Tutorial. 1. cd Service. Tutorial. 1At this time, a Microsoft Visual Studio Project named Service. Tutorial. 1. csproj is created in Service. Tutorial. 1 directory. You can load this Project using your C# editor (either Visual Studio or Visual Studio Express) from the command line as shown below, or locate it in Windows Explorer and double- click on it. Consolestart Service. Tutorial. 1. csproj. When you edit a project that does not have a Solution file (Service. Tutorial. 1. sln in this case), Visual Studio will ask if you want to create a Solution file when you exit. This is the easiest way to create the Solution file. Note that you do not need a Solution file in order to compile and use the service - the Project file is sufficient. Next, build the solution. C# application auto run on Windows. How to make an Application auto run on Windows startup.In Visual Studio you can build the solution by clicking Build menu and then choosing Build Solution (or pressing F6). You can also compile from the DSS Command Prompt: Consolemsbuild Service. Tutorial. 1. sln. The command above assumes you have created the Solution file. If not, then just build the . Lastly, note that you can also create a new service using a Wizard in Visual Studio. This is much easier and has more functionality than using the command- line tool. See Creating Service Projects for more information. Step 2: Start a Service. Go back to the Microsoft Robotics Developer Studio (RDS) installation folder. You should now see the following files in the bin directory that were created when you built your project. So depending on the current date, the build names for the Service. Tutorial. 1 files that you just created may be different from the ones you see in the above sample. You may also see other Service. Tutorial. 1 files with different dates that are coming from the Service. Tutorial. 1 project installed with Robotics Developer Studio. To run a service, you must first run a DSS node by running the DSS hosting application Dss. Host. exe. Dss. Host can start services for you. There are 3 ways to specify which service or services Dss. Host should start: By manifest, using the command line flag /manifest. By assembly name, using the command line flag /dll. By contract, using the command line flag /contract. A manifest file is an XML file that contains the information needed to start a service. Dss. New. Service automatically creates a file called Service. Tutorial. 1. manifest. Dss. Host to start the service. Start Dss. Host using the manifest already created with the following command. Consoledsshost /port: 5. If you are using the Service. Tutorial. 1 project in samples\Service. Tutorials\Service. Tutorial. 1 folder you should run Dss. Host with the right manifest from samples\Config. You should see service load outputs for the specified manifest: Console. Figure 1 - http: //localhost: 5. SOAP envelope. Exit DSS host by pressing CTRL+C in the command window. Step 3: Support HTTP GETWhen sending state to a web browser, the service can optionally avoid sending a SOAP envelope and instead send an XML serialization of its state as follows. The Service. Tutorial. Types. cs file defines the Contract of the service. It includes types for contract identifier, state, operations port, operation messages, and request/response types for this service. You will learn more about the components of services as you go through these tutorials. In the file Service. Tutorial. 1Types. First add a using directive to the top of the file to include the namespace Microsoft. Dss. Core. Dssp. Http. This namespace contains the message definitions that allow a service to respond directly to requests from a standard HTTP client, such as a standard web browser. C#using Microsoft. Dss. Core. Dssp. Http; Next, add a property to the class Service. Tutorial. 1State, this will allow us to see the serialized data more clearly. In Service Tutorial 6 (C#) - Retrieving State and Displaying it Using an XML Transform you will use the Service. Tutorial. 1State class to carry information between services. Within a type marked with the Data. Contract attribute, you must explicitly mark individual properties and fields as XML serializable using the Data. Member attribute. Only public properties and fields declared with this attribute will be serialized. Also, in order for the property members to serialize, they will need to have both the set and get methods implemented. Attributes is a feature in . NET that allows adding keyword- like annotations to programming elements such as types, fields, methods, and properties. To learn more about . NET attributes see Attributes Overview in the . NET Framework Developer's Guide. Now, further down in the same file, add the Http. Get message to the list of messages supported by the service's port. A port is a mechanism through which messages are communicated between services. A Port. Set is just a collection of ports. Service. Tutorial. Again add a using statement for Dssp. Http. C#using Microsoft. Dss. Core. Dssp. Http; Then in the Service. Tutorial. 1 class, add a message handler for the Http. Get message. C#/// < summary>. Http Get Handler. This is a standard Http. Get handler. It is not required because. Dssp. Service. Base will handle it if the state is marked with . The HTTP infrastructure within the DSS node will serialize the provided state to XML and set that as the body of response to the HTTP request. IMPORTANT NOTE: This is the default behavior of a Http. Get handler. The resulting output will be an XML serialized version of the service state. If this is the behavior that you want, then there is no need to write the Http. Get code into your service because Dssp. Service. Base will take care of it for you if you tag your state with the Service. State attribute. The Http. Response. Type constructor has other overloads than the one used here. One of these overloads allows the service author to specify the path of an XSLT file that can be used by a web client to transform the serialized XML. An alternative, which is especially useful because you do not have to declare a Http. Get handler, is to specify the transform using the attribute . Build and run the service (press F5 or select the Debug > Start Debugging menu command) and, while it is running, use a web browser to navigate to http: //localhost: 5. Figure 2 - State of the service in browser shows Service. Tutorial. 1State and its members. Step 4: Using Control Panel. To start your service you could also use DSS Control Panel, which is itself a DSS service. To try this, first terminate the current DSS node by pressing CTRL+C in the command prompt. Then run Dss. Host again without supplying a manifest. Consoledsshost /port: 5. Now open http: //localhost: 5. When the page is loaded, in the left navigation pane click on Control Panel. A table of services recognized by the current node appears in your browser. Figure 3 - View of DSS Control Panel in the browser. Each row of the table begins with the Name of a service. Following that there is a dropdown list with the list of manifests that can run the service. If there are any instances of that service which are currently running, you should see a URL for that instance under the service's Description. Each instance of a running service also includes a button in the right- hand side of the URL which allows you to Drop that service. Clicking this button sends a Drop message to the service. This message stops the service. Scroll down the page and find the entry for Service. Tutorial. 1 or type the name of your service in the Search box: servicetutorial. Figure 4 - Entry for Service. Tutorial. 1 in Control Panel You will probably see two results. One of them is the Service Tutorial 1 from the completed project that comes with a DSS installation. You can distinguish them by looking at the location of manifests in the dropdown lists, however, for running this service you don't need to select a manifest and can do it by directly loading the assembly (dll file) by selecting < < Start without manifest> >. In cases where you need to run your service together with a group of partner services that are listed in the manifest, you will need to run the manifest instead. Run the service by clicking on the Create button. Now from the left navigation pane select Service Directory. You should see /servicetutorial. Make a service that keeps program running. Do you have any logging happening?
