September 5, 2010 by Paul Cunningham 225 Comments. VB. Net Quick Guide Learn VB. Net Programming in simple and easy steps starting from Environment setup, Basic Syntax, Data Types, Type Conversion, Variables. This is a demonstration only, and should not be taken as a recommendation to use Windows NLB for your load balancing. A dedicated hardware or virtual load balancer will provide much better performance and capability than NLB can, for any Exchange version. If youre new to the concept of Client Access Server arrays and need to know more then check out this article for an introduction and overview of CAS Arrays. Client Access Server Array Pre Requisites. Two or more Exchange Server 2. Client Access Servers can be configured as a CAS array using NLB as long they are not also installed as Mailbox servers that are members of a Database Availability Group DAG. The reason is that DAG members utilize Windows Failover Clustering, which cant co exist with NLB. To demonstrate the setup of a CAS array the following servers have been provisioned. Server 1. Operating System Windows Server 2. R2. Name EX3. exchangeserverpro. Primary Interface 1. Secondary Interface 1. Server 2. Operating System Windows Server 2. R2. Name EX4. exchangeserverpro. Primary Interface 1. Secondary Interface 1. The IP address allocated to the NLB cluster will be 1. Installing the Exchange Server 2. Client Access Server Pre Requisites. On each server, from an elevated Windows Power. Shell prompt, run the following commands. PS C Import Module Server. Manager. PSC Import Module Server. Manager. Note In my lab the servers are also Hub Transport servers, and so I installed both sets of pre requisites. Try this. You need Quest Active directory cmdlets for powershell to run this script. Give the list of SamAccountNames as input in cusers. Active Directory AD is a distributed directory service created by Microsoft. It stores all information and settings for a deployment in a central database. Visual Basic. NET VB. NET is a multiparadigm, managed, typesafe, objectoriented computer programming language. Along with C and F, it is one of the main. I also use the Restart switch to automate the restart of the servers, however you can remove this if you wish to control when the servers are restarted.

Note Again, my lab servers are also Hub Transport servers. For only the Client Access Server role with Management Tools. C admin. Exchange Server 2. C admin. Exchange Server. For both the Client Access and Hub Transport Server roles with Management Tools. C admin. Exchange Server 2. C admin. Exchange Server. Installing Windows Network Load Balancing. On each of the servers, from an elevated Power. Shell window run the following commands. PS C Import Module servermanager. PSC Import Module servermanager. PS C Add Windows. Feature NLBPSC Add Windows. Feature NLBCreating the NLB Cluster. After both servers have been prepared the NLB cluster can be created. On the first server launch the Network Load Balancing Manager from Administrative Tools. From the Cluster menu choose New. Connect to the first server for the NLB cluster. Choose the interface that is to be used for the cluster, and then click Next. Accept the default Host parameters and click Next. Click Add and enter an IPv. NLB cluster, then click OK. Click Next to continue. Enter a name for the cluster. In this example Im using casarray. Click Next to continue. Although the port rules can be made more specific, in this example the default rule is acceptable. Click Finish to complete the creation of the NLB cluster. At this stage you should have a single host NLB cluster that is successfully converged. Right click the cluster name and choose Add Host to Cluster. Enter the name of the second server and click Connect. Choose the interface to be used for the cluster and click Next. Accept the default Host Parameters and click Next. There are no changed necessary to the port rules, so click Finish. You should now have a dual host NLB cluster that is successfully converged. One final step, on each of the NLB members run the following command to allow the NLB virtual IP address to be reachable from outside of the subnet that it resides in. NLB forwardingenablednetsh interfaceipv. NLBforwardingenabled. Replance NLB with the name of your NLB interface on your server. Creating the Client Access Server Array. Now that the NLB cluster has been formed we can create the CAS array in Exchange Server 2. First, register a DNS record for the NLB cluster name. Next, launch the Exchange Management Shell on one of the Exchange servers and run the following command. PS C New Client. Access. Array Name CASArray Site Default First Site Name Fqdn casarray. Name Site Fqdn Members. CASArray Default First Sit. EX3, EX4PSC New Client. Access. Array Name CASArray SiteDefault First Site Name Fqdn casarray. CASArray            Default First Sit. EX3,EX4Substitute the Name, Site, and FQDN as appropriate for your environment. Updating Existing Mailbox Databases. When the CAS array has been established any new mailbox databases created on servers in that Active Directory Site will be configured with the CAS array as their Rpc. Client. Access. Server. However any existing mailbox databases need to be manually updates so that those mailbox users begin connecting to the new CAS array. You can see here that the existing mailbox database on server EX2 is still configured with a standalone Client Access server as its Rpc. Client. Access. Server. PS C Get Mailbox. Database Server EX2 fl name, rpc. Name Mailbox Database 0. Rpc. Client. Access. Server EX3. exchangeserverpro. PSC Get Mailbox. Database Server EX2fl name,rpcpc. Client. Access. Server EX3. To update all databases on the server with the new Rpc. Client. Access. Server run the following command. PS C Get Mailbox. Database Server EX2 Set Mailbox. Auto Hide Ip 5 3 1 2. Database Rpc. Client. Access. Server casarray. PSC Get Mailbox. Database Server EX2Set Mailbox. Database Rpc. Client. Access. Server casarray. The change can be seen by running the same command as earlier. PS C Get Mailbox. Database Server EX2 fl name, rpcVB. Net Quick Guide. VB. Net Quick Guide. VB. Net Overview. Visual Basic. NET VB. NET is an object oriented computer programming language implemented on the. NET Framework. Although it is an evolution of classic Visual Basic language, it is not backwards compatible with VB6, and any code written in the old version does not compile under VB. NET. Like all other. NET languages, VB. NET has complete support for object oriented concepts. Everything in VB. NET is an object, including all of the primitive types Short, Integer, Long, String, Boolean, etc. All objects inherits from the base class Object. VB. NET is implemented by Microsofts. NET framework. Therefore, it has full access to all the libraries in the. Net Framework. Its also possible to run VB. NET programs on Mono, the open source alternative to. NET, not only under Windows, but even Linux or Mac OSX. The following reasons make VB. Net a widely used professional language Modern, general purpose. Object oriented. Component oriented. Easy to learn. Structured language. It produces efficient programs. It can be compiled on a variety of computer platforms. Part of. Net Framework. Strong Programming Features VB. Net. VB. Net has numerous strong programming features that make it endearing to multitude of programmers worldwide. Let us mention some of these features Boolean Conditions. Automatic Garbage Collection. Standard Library. Assembly Versioning. Properties and Events. Delegates and Events Management. Easy to use Generics. Indexers. Conditional Compilation. Simple Multithreading. VB. Net Environment. In this chapter, we will discuss the tools available for creating VB. Net applications. We have already mentioned that VB. Net is part of. Net framework and used for writing. Net applications. Therefore before discussing the available tools for running a VB. Net program, let us understand how VB. Net relates to the. Net framework. The. Net Framework. The. Net framework is a revolutionary platform that helps you to write the following types of applications Windows applications. Web applications. Web services. The. Net framework applications are multi platform applications. The framework has been designed in such a way that it can be used from any of the following languages Visual Basic, C, C, Jscript, and COBOL, etc. All these languages can access the framework as well as communicate with each other. The. Net framework consists of an enormous library of codes used by the client languages like VB. Net. These languages use object oriented methodology. Following are some of the components of the. Net framework Common Language Runtime CLRThe. Net Framework Class Library. Common Language Specification. Common Type System. Metadata and Assemblies. Windows Forms. ASP. Net and ASP. Net AJAXADO. Net. Windows Workflow Foundation WFWindows Presentation Foundation. Windows Communication Foundation WCFLINQFor the jobs each of these components perform, please see ASP. Net Introduction, and for details of each component, please consult Microsofts documentation. Integrated Development Environment IDE For VB. Net. Microsoft provides the following development tools for VB. Net programming Visual Studio 2. VSVisual Basic 2. Express VBEVisual Web Developer. The last two are free. Using these tools, you can write all kinds of VB. Net programs from simple command line applications to more complex applications. Visual Basic Express and Visual Web Developer Express edition are trimmed down versions of Visual Studio and has the same look and feel. They retain most features of Visual Studio. In this tutorial, we have used Visual Basic 2. Express and Visual Web Developer for the web programming chapter. You can download it from here. It gets automatically installed in your machine. Please note that you need an active internet connection for installing the express edition. Writing VB. Net Programs on Linux or Mac OSAlthough the. NET Framework runs on the Windows operating system, there are some alternative versions that work on other operating systems. Mono is an open source version of the. NET Framework which includes a Visual Basic compiler and runs on several operating systems, including various flavors of Linux and Mac OS. The most recent version is VB 2. The stated purpose of Mono is not only to be able to run Microsoft. NET applications cross platform, but also to bring better development tools to Linux developers. Mono can be run on many operating systems including Android, BSD, i. OS, Linux, OS X, Windows, Solaris and UNIX. VB. Net Program Structure. Before we study basic building blocks of the VB. Net programming language, let us look a bare minimum VB. Net program structure so that we can take it as a reference in upcoming chapters. VB. Net Hello World Example. A VB. Net program basically consists of the following parts Namespace declaration. A class or module. One or more procedures. Variables The Main procedure. Statements Expressions. Comments. Let us look at a simple code that would print the words Hello World. This program will display Hello World. Console. Write. LineHello World. Console. Read. Key. When the above code is compiled and executed, it produces the following result. Let us look various parts of the above program The first line of the program Imports System is used to include the System namespace in the program. The next line has a Module declaration, the module Module. VB. Net is completely object oriented, so every program must contain a module of a class that contains the data and procedures that your program uses. Classes or Modules generally would contain more than one procedure. Procedures contain the executable code, or in other words, they define the behavior of the class. A procedure could be any of the following. Function. Sub. Operator. Get. Set. Add. Handler. Remove. Handler. Raise. Event The next line This program will be ignored by the compiler and it has been put to add additional comments in the program. The next line defines the Main procedure, which is the entry point for all VB. Net programs. The Main procedure states what the module or class will do when executed. The Main procedure specifies its behavior with the statement. Console. Write. LineHello WorldWrite. Line is a method of the Console class defined in the System namespace. This statement causes the message Hello, World to be displayed on the screen. The last line Console. Read. Key is for the VS. NET Users. This will prevent the screen from running and closing quickly when the program is launched from Visual Studio. NET. Compile Execute VB. Net Program If you are using Visual Studio. Net IDE, take the following steps Start Visual Studio. On the menu bar, choose File, New, Project. Choose Visual Basic from templates. Choose Console Application. Specify a name and location for your project using the Browse button, and then choose the OK button. The new project appears in Solution Explorer. Write code in the Code Editor. Click the Run button or the F5 key to run the project. A Command Prompt window appears that contains the line Hello World. You can compile a VB. Net program by using the command line instead of the Visual Studio IDE Open a text editor and add the above mentioned code. Save the file as helloworld. Open the command prompt tool and go to the directory where you saved the file. Type vbc helloworld.
