Vb Console Application Tutorial
To start up Visual Studio Express for the first time, go to the Start screen on Windows 8 or the Start menu on Windows 7 and look for the Menu Choice or tile for Visual Studio Express for desktop. You'll see that it's named VS Express. If this is the first time you've started up Visual Studio on your system, you'll be asked to register and provide a serial number. Follow the prompts and check your email for the serial number that will be emailed to you by Microsoft. Registration is free, but required.
Once you've started it up you'll be able to create your first project. To create a project, go to the Menu and choose File > New Project. Visual Studio Express for Windows Desktop lets you create applications using three programming languages, Visual Basic, Visual C#, and Visual C++. Within the Visual Basic section, choose the Windows category and you'll find a number of options. You can build three different types of applications, a Windows Forms application, a WPF or Windows Presentation Foundation application, or a Console application.
So, you can develop a console application in Visual Basic, create an executable file, and then, use my utility to convert the executable into a console application. My utility was developed in Visual Basic, and the source code is provided within the sample package. You can use it by opening the appmodechange project from Visual Basic IDE. Console.Write('This is my first Console Application') Read End Sub End Module. And now press the Start Debugging button or F5 button on your keyboard to execute the Console Application. The output of Console Application is: Summary. Hope this article help you to Understand about Console Application and its execution in Visual Basic. Quickstart: Create your first console app in Visual Studio with Visual Basic.; 3 minutes to read +1; In this article. In this 5-10 minute introduction to the Visual Studio integrated development environment (IDE), you'll create a simple Visual Basic application that runs on the console. Aug 10, 2018 In this tutorial for Visual Basic (VB), you'll use Visual Studio to create and run a few different console apps and explore some features of the Visual Studio integrated development environment (IDE) while you do so. If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free.
Visual Basic Tutorial. Create a new Visual Basic Console Application and name it Classes. In solution explorer, right click on classes and make a new class file. I am trying to use a Timer control in my console application. Friend WithEvents XTIMER As System.Windows.Forms.Timer I am setting all its properties. I have set the interval to 15000 ms.
Create a Console Application. After selecting that option, name the application Console First App. I'm placing the application and project in my exercisefiles02gettingstarted folder, but you can place it anywhere you like. A Console App starts off as a simple Visual Basic file called a module. And it has a subroutine or a method called Main. This Main method will be executed automatically as the application starts up.
So place the cursor between the sub declaration and the end sub declaration. And any code you put there will be executed. Our first step is to execute a simple, hello world, outputting a simple string. And I'll use an expression that looks like this. Console.WriteLine. In Visual Studio, you can auto complete code by pressing the Tab key. So I started typing write and then I moved the cursor to WriteLine and pressed Tab.
Now I'll put in an opening parenthesis and then a simple string of, hello world. In Visual Basic you don't need to finish the line with a semi colon or any other punctuation. All you need is the end of the statement and in this case that's the closing parenthesis. I'll save my changes with Ctrl+s, and then I'll run the application. When you're working with a console application, if you run with debugging, you'll see that the console window flies by very, very fast, but doesn't stay open.
If all you're doing is outputting content into the console, run without debugging, and you can do that by going to the Menu and choosing Debug > Start Without Debugging, or pressin Ctrl+F5. And there is the result. I see the string, Hello World, and a prompt, press any key to continue. And when I press any key the console window closes. Now I'll add a few more lines of code. I'm going to declare a couple of simple variables.
In Visual Basic you declare a variable using the key word dim. I'll talk about what that keyword does and what it means later. But for now, all you need to know is that every variable should start with dim. Then, assign the variable name. I'll set it as value one and I'll give it a value of five. If you already know c style languages, such as C, C++, or Java, you might be wondering at this point whether you need to declare data types. That is, whether a variable is an integer, a double, a string, or some other type.
And the answer is, in Visual Basic, you don't have to. You can follow a pattern known as typeless programming, where you let the Visual Studio compiler infer the data types. In this case, I'm saying that the value is 5 and the compiler will respond by saying that the value 1 is an integer. Next I'll declare a second variable. I will say Dim value2 equals 20. You may have noticed that I was prompted for a keyword called as, but I'm not going to use that right now.

Extends the field of application of ISO 7498.
Finally I will declare a third variable named total. And I'll get its value by adding the first two variable together with this statement. Dim total equals value one plus value two. Just as I did earlier, with Autocompleting Command, you can also autocomplete variable names. For example, if I type in just val. I'll see a list of all available identifiers that have that string and I can choose the one I want and press tab. Now, I'll output to the console again.
I'll once again use Console.WriteLine and I'll output a concatenated string. That's two strings put together. I'll start with the result is and then I'll append to that by putting in a plus operator and then I'll output total.ToString. That's how you convert a number to a string. I'll save my changes, once again with Ctrl S. And I'll run with Control F5, and there's the result.
25. So that's a look at how to build a very simple console application in Visual Studio using the visual basic programming language. We'll talk a a lot more about this code and the concept of typeless programming later on in the course. And for most of this course I won't be building console applications. I'll be building Windows Presentation Foundation or WPF-based desktop applications but if you need to use a console application, this is how you get started.
-->In this 5-10 minute introduction to the Visual Studio integrated development environment (IDE), you'll create a simple Visual Basic application that runs on the console.

Create a project
First, you'll create a Visual Basic application project. The project type comes with all the template files you'll need, before you've even added anything!
Open Visual Studio 2017.
From the top menu bar, choose File > New > Project.
In the New Project dialog box in the left pane, expand Visual Basic, and then choose .NET Core. In the middle pane, choose Console App (.NET Core). Then name the project HelloWorld.
If you don't see the Console App (.NET Core) project template, click the Open Visual Studio Installer link in the left pane of the New Project dialog box.
The Visual Studio Installer launches. Choose the .NET Core cross-platform development workload, and then choose Modify.
Note
Some of the screenshots in this Quickstart use the dark theme. If you aren't using the dark theme but would like to, see the Personalize the Visual Studio IDE and Editor page to learn how.
Open Visual Studio 2019.
On the start window, choose Create a new project.
On the Create a new project window, enter or type console in the search box. Next, choose Visual Basic from the Language list, and then choose Windows from the Platform list.
After you apply the language and platform filters, choose the Console App (.NET Core) template, and then choose Next.
Note
If you do not see the Console App (.NET Core) template, you can install it from the Create a new project window. In the Not finding what you're looking for? message, choose the Install more tools and features link.
Then, in the Visual Studio Installer, choose the .NET Core cross-platform development workload.
After that, choose the Modify button in the Visual Studio Installer. You might be prompted to save your work; if so, do so. Next, choose Continue to install the workload. Then, return to step 2 in this 'Create a project' procedure.
In the Configure your new project window, type or enter WhatIsYourName in the Project name box. Then, choose Create.
Visual Studio opens your new project.
Create the application
After you select your Visual Basic project template and name your project, Visual Studio creates a simple 'Hello World' application for you. It calls the WriteLine method to display the literal string 'Hello World!' in the console window.
If you click the HelloWorld button in the IDE, you can run the program in Debug mode.
When you do this, the console window is visible for only a moment before it closes. This happens because the Main method terminates after its single statement executes, and so the application ends.
Add some code
Let's add some code to pause the application and then ask for user input.
Add the following code immediately after the call to the WriteLine method:
This pauses the program until you press a key.
On the menu bar, select Build > Build Solution.
This compiles your program into an intermediate language (IL) that's converted into binary code by a just-in-time (JIT) compiler.
Run the application
Visual Basic Console
Click the HelloWorld button on the toolbar.
Press any key to close the console window.
