A VB.net Program Structure<\/strong> is constructed using standard components. One or more projects make up a solution. <\/p>\n\n\n\n <\/p>\n\n\n\n One or more assemblies can be found within a project. Each assembly is made up of several source files. <\/p>\n\n\n\n <\/p>\n\n\n\n A source file contains all of your code and contains the definition and implementation of classes, structures, modules, and interfaces.<\/p>\n\n\n\n <\/p>\n\n\n\n Let’s look at a bare minimum VB.net program structure<\/strong> before we look at the basic building elements<\/strong> of the VB.Net programming language, so we can use it as a reference in the next chapters.<\/p>\n\n\n\n A VB.net program is made up of the following components:<\/p>\n\n\n\n <\/p>\n\n\n\n Consider the following code, which prints the words “Hello World.”<\/p>\n\n\n\n <\/p>\n\n\n\n You can test the above example here! \u27a1 VB.net Online Compiler<\/a><\/strong><\/p>\n\n\n\n <\/p>\n\n\n\n When the preceding code is compiled and run, the following is the result:<\/p>\n\n\n\n <\/p>\n\n\n\n Let us look at various parts of the above program.<\/p>\n\n\n\n <\/p>\n\n\n\n Before we start compiling and executing the vb.net program, make sure that you have already installed Microsoft Visual Studio<\/a> on your computer.<\/p>\n\n\n\n Time needed: <\/span>5 minutes<\/p> Compile & Execute VB.net Program<\/strong><\/p> First, open the Microsoft Visual Studio IDE. Next, On the menu bar, choose File<\/em><\/strong> \u2192 New<\/em><\/strong> \u2192 Project<\/em><\/strong>. Next, select the console app and click next. Next, Specify a name and location for your project using the Browse button, and then choose the OK button. Next, as you can see the console project appears on the solution explorer. Next, as you can see there’s already code in the code editor area. Next, click the run button to execute the program. Last, the console will display the output of the executed program. <\/p>\n\n\n\n You can compile a VB.net program by using the command line instead of the Visual Studio IDE<\/p>\n\n\n\n Open a text editor and add the above-mentioned code.<\/p>\n\n\n\n <\/p>\n\n\n\n Save the file as helloworld.vb<\/em><\/strong>.<\/p>\n\n\n\n <\/p>\n\n\n\n Open the command prompt<\/em><\/strong> tool and go to the directory where you saved the file.<\/p>\n\n\n\n <\/p>\n\n\n\n Type vbc helloworld.vb<\/em><\/strong> and press enter to compile your code.<\/p>\n\n\n\n <\/p>\n\n\n\n If there are no errors in your code the command prompt will take you to the next line and would generate helloworld.exe<\/em><\/strong> executable file.<\/p>\n\n\n\n <\/p>\n\n\n\n Next, type helloworld<\/em><\/strong> to execute your program.<\/p>\n\n\n\n <\/p>\n\n\n\n You will be able to see “Hello,World<\/strong>!” printed on the screen.<\/p>\n\n\n\n <\/p>\n\n\n\n A VB.net program<\/strong> is composed of various parts. After importing a namespace<\/strong> into a program, it becomes possible for us to use all the methods<\/strong> and functions<\/strong> that have been defined in that module<\/strong>. <\/p>\n\n\n\n <\/p>\n\n\n\n Every VB.net program must have a module.

Summary<\/strong><\/h2>\n\n\n\n
The VB.net compiler ignores comments. We can have more than one procedure in a VB.net program<\/strong>.<\/p>\n\n\n\n
