RDP Remote Desktop Protocol is a protocol developed by Microsoft that provides a user with a graphical interface to connect to another computer over a network connection. Windows Remote Desktop Services is a server based presentation virtualization component that allows a user to access applications and data hosted on a remote computer over a network.

Desktop virtualization is a software technology that can separate the desktop environment and its associated applications from the physical client that is used to access it. Desktop virtualization can be used together with application virtualization and user virtualization to provide a complete desktop environment management system. In Desktop virtualization, all the components of the desktop are virtualized, which allows for a flexible and more secure desktop delivery model. Application Virtualization. Application virtualization is a software technology that envelops programs from the underlying operating system. A virtualized application behaves at runtime as if it is directly interfacing with the original operating system. User Virtualization. User virtualization separates all of the software aspects that define a users personality from the operating system. Our Project. Today, you will create an application in Visual Basic. NET capable of making Remote Desktop Connections. Start Visual Basic and create a new Windows Forms project. When the project has finished loading, add three textboxes and two buttons onto it. The textboxes will be used to enter the Server name, User name, and Password. The two buttons will be used to Connect and Disconnect. Make your form much bigger than the default size. Use the following steps to add a reference to Microsoft Terminal Services Active Client Click Project. Click Add Reference. On the COM tab, scroll down until you find Microsoft Terminal Services Active Client and tick it see Figure 1. Figure 1 Add a Reference. Use the following steps to add the Microsoft Terminal Services Client Control to your Toolbox Right click your Toolbox. Click Choose Items. Select the COM Components tab. Scroll down until you find Microsoft Terminal Services Client and tick it, as shown in Figure 2. Click OK. Figure 2 Toolbox Items. Your Toolbox should show two new controls inside see Figure 3. Figure 3 New tools. Add the Terminal Services Client Control to your form. Your forms final design should resemble Figure 4. Figure 4 Design. The design is set up nicely now. You have to add the reference to get the Toolbox items so that we can add them onto the form. Code. Import the Microsoft Terminal Services Client Library namespace Imports MSTSCLib.

Retrieve a List of Installed Printers on the Network Using WMI, C and VB. NETRetrieve a List of Installed Printers on the Network Using WMI, C and VB. NETA common requirement is to display a list of printers on the network. In this article, we will explore how to do so. We will be using Windows Management InstrumentationWMI to access this information. WMI is like an interface for retrieving management information in an enterprise environment. To display the list of printers on your network, follow these steps Step 1 Create a Windows Form application and drag and drop a Combo. Boxcmb. Printers and a Buttonbtn. Get. Printers to the form. Step 2 Right Click Project Add Reference Select. NET Tab System. Management. Also add the following namespace in the Form. Cusing System. Management VB. NETImports System. Management. The System. Management namespace provides information and events about devices and applications instrumented to the WMI infrastructure. Step 3 Double click the button to generate an event handler and add the following code C       privatevoid btn. Get. PrintersClickobject sender, Event. Args e        Use the Object. Query to get the list of configured printers            System. Management. Object. Query oquery                 new System. Management. Object. QuerySELECT FROM Win. Printer            System.

Addmopd. Name                                                        VB. NET         Private. Sub btn. Get. PrintersClickBy. Val sender As. Object, By. Val e As Event. Args Use the Object. Query to get the list of configured printers                  Dim oquery As System. Management. Object. Query New System. Management. Object. QuerySELECT FROM Win. Printer                  Dim mosearcher As System. Management. Management. Object. Searcher New System. Management. Management. Object. Searcheroquery                  Dim moc As System. Management. Management. Object. Collection mosearcher. Get                  For. Each mo As Management. Object In moc                        Dim pdc As System. Management. Property. Data. Collection mo. Properties                        For. Each pd As System. Management. Property. Data In pdc                              If. CBoolmoNetwork Then                                    cmb. Printers. Items. Addmopd. Name                              End. If                        Next pd                  Next mo         End. Sub. In the code above, an instance of the Object. Query class is created to fetch a list of configured printers. This instance of the Object. Query is then passed to the constructor of the Management. Object. Searcher class to retrieve a collection of management objects, in our case, printers. We then call the Get method on the instance of the Management. Object. Searcher class, to execute the query and return a list of printers to the instance of Management. Object. Collection. The last step is to enumerate this collection and retrieve a set of properties of the WMI object. The Management. Object is indexed with the propertyname to retrieve the name of the printer and is added to the Combo. Box items. Note If you only want to get a list of printers installed on your local machine, you do not necessarily have to use WMI. It can be as simple as retrieving information using the System. Drawing. Printing. Printer. Settings. Installed. Printers collection as shown below. C            foreach string printer in System. Drawing. Printing. Printer. Settings. Installed. Printers                            Message. Box. Showprinter            VB. NET                  For. Each printer As. String. In System. Drawing. Printing. Printer. Settings. Installed. Printers                        Message. Box. Showprinter                  Next printer. Thats it. If you are interested in delving deeper into System. Management, you can do so by checking this MSDN documentation. This namespace has several uses like finding out information such as CPU utilization, disk free space etc. I would encourage you to explore the various classes of this namespace.
