Using Visual Studio .NET Management Extensions and the POS for .NET WMI Management Classes (POS for .NET v1.14 SDK Documentation)

3/3/2014

You can use Server Explorer in Microsoft Visual Studio 2013 to navigate the Microsoft.PointOfService namespace and drag the instances of the classes into your project’s Class Designer.

This feature requires that Visual Studio 2013 and POS for .NET are installed on the local development computer.

To use the extension

1. Launch Visual Studio 2013 and, from the VIEW menu, open the Server Explorer window.

2. Expand the Servers node, and then expand the Machine node.

3. Right-click the Management Classes node and then click Add Classes on the shortcut menu.

4. In the Add Classes dialog box, expand the root\MicrosoftPointOfService node in the Available Classes tree view.

5. Select the DeviceProperty class, and then click Add to add the class to the Server Explorer. Repeat this step for the LogicalDevice, PosDevice, and ServiceObject classes.

To use the management classes

1. Create a .NET project.

2. Open the Server Explorer.

3. Right-click the DeviceProperty node, and then click Generate Managed Class on the shortcut menu to add the generated class to the project. Repeat this step for the LogicalDevice, PosDevice, and ServiceObject classes to generate managed classes.

To use an instance of a management class

1. In the Server Explorer, expand the desired class to list the available class objects.

2. Drag the instances onto the projects class designer.

Example

The following code example demonstrates the use of the PosDevice class GetInstances method to enumerate Point of Service devices. It creates a collection of the devices within a scope. It then lists the type, name and path for each device in the collection and indicates whether the device is enabled or disabled.

using System;
using System.Management;
using ROOT.MICROSOFTPOINTOFSERVICE;

namespace Management
{
   public class Test
   {
      public Test()
      {
         ManagementScope scope = new ManagementScope("root\\microsoftpointofservice");
         scope.Connect();
         PosDevice.PosDeviceCollection devices = PosDevice.GetInstances(scope, "");
         string format = "{0,10}\t{1,25}\t{2}\t{3,50}";
         if( devices.Count > 0 )
            Console.WriteLine(format, "Type", "Name", "Enabled", "Path");
         foreach( PosDevice d in devices )
         {
            Console.WriteLine(format, d.Type, d.SoName, d.Enabled ? 'Y' : 'N', d.Path); 
         }
      }

      static int Main()
      {
         Test t = new Test();
         return 0;
      }
   }
}
