Deploying your Visual Basic 2017 Applications

Having developed a Visual Basic 2017 application, you might want to publish and distribute it to the users.

Before deploying your application,  you need to test and debug your application to ensure it is error-free.

Publishing your application is a very easy procedure, it just requires a few clicks. First of all, load your application in Visual Basic 2017. In this example, I wish to publish my Draw Text application. In the VB2017 IDE, choose Build and then select Publish Draw text, as shown in the following figure.

publish visual basic 2017

After clicking Publish Draw Text, the Publish Wizard will ask you to choose a location that you want to publish this application. You may publish the application on your local drive or to a remote location via FTP, as shown in the following figure:

Click the Next button to continue. Now, the Publish Wizard will ask you how will users install the application. There are three options,  from a website,  from a UNC path or file share and from a CD-ROM or DVD-ROM. In this example, we choose CD-ROM or DVD-ROM, as shown in the following figure:

You may click the Next button to continue with the Publish Wizard or the Finish button to complete the publishing process. If you click the Next button, the Publish Wizard will ask where will the application check for updates. In our example, we choose that the application will not check for updates, as shown in the following figure.

After clicking the Next button, the final screen of the Publish Wizard will show you where the application will be published to.

Upon clicking the Finish button, the installation files and folder will be saved to the specified location. In our examples, the folder is Application files and the files are Draw text.application and setup.exe. You may now burn the folder and files into a CD-ROM, DVD-ROM or upload them to a website for distribution to the users.

 


Creating Board Games in Visual Basic

We can create board games in Visual Basic. Creating board games require some basic knowledge of maths as we need to perform some calculations. For example, we need to use the knowledge of matrix to create a board for the snakes and ladders game. Besides that, we also need to write decision-making code to deal with board games, as shown in the reversi game, where we use the If…Then..Else statements to check how many white and black pieces appear on the reversi board and which positions they occupy.

In the case of Tic Tac Toe , we need to use the Boolean logic to check the adjacent slots are empty or not. In the game of Star War, we use the principle of the projectile in physics to chart the paths of motion.


Visual Basic 2017 Built-In Functions

This year Microsoft introduced the latest version of Visual Basic, Visual Basic 2017.  It is included in the latest Visual Studio package, Visual Studio Community 2017.

Visual Basic 2017 includes numerous built-in functions to make programming jobs easier. These functions are categorized as follows:

  1. Mathematical functions
  2. Trigonometric Functions
  3. Format Functions

Of course, you can also create your own functions. Learn how to create your own functions in VB2017 from the following link

Creating Financial Calculators

You can create all kinds of financial calculators in Visual Basic easily as long as long you know the relevant formulas.

For example, you can create a future value calculator using the following formula:

FV = PV * (1 + i / 100)n

FV=Future Value

PV=Present Value

i=Interest

n=Number of periods

You simply create a function for the future value, as follows:

Private Function FV(pv As Single, i As Single, n As Integer) As Double
FV = pv * (1 + i / 100) ^ n
End Function

You then write code for a button where it can compute the future value when the user clicks on the button, as follows:

Private Sub BtnCal_Click(sender As Object, e As EventArgs) Handles BtnCal.Click

Dim FutureVal As Single
Dim PresentVal As Single
Dim interest As Single
Dim period As Integer

PresentVal = TxtPV.Text
interest = TxtInt.Text
period = TxtN.Text
FutureVal = FV(PresentVal, interest, period)
LblFV.Text = Format(FutureVal, “$#,##0.00”)

End Sub

Some of the financial calculators created by us are:


Writing Maths and Science Programs

It is fairly easy to write maths and science programs in Visual Basic. Basically, it involves the use of arithmetic operators, mathematical expressions, functions, formulas, and equations. For example, Here are some examples:
