Array size is often defined during design time. This type of array is known as static array. However, the problem is sometimes we might not know how many data items we need to store during run time. In this case, we need to use dynamic array where the number of elements will be decided during run time. In Visual Basic 2017, the dynamic array can be resized when the program is executing. The first step in declaring a dynamic array is by using the Dim statement without specifying the dimension list, as follows:
Then at run time we can specify the actual array size using the ReDim statement,as follows:
* n =array size
You can also declare a two dimensional array using ReDim statement, as follows:
ReDim myArray(n, m)
*mxn indicates the array size.
The String function has two arguments, a number and a single-character string, and returns a string consisting of the specified character repeated the speficified number of times. Follow the link below to read more.

To start programming in Visual Basic 2017, you need to launch Visual Studio 2017 RC. The following is the start page of Visual Studio 2017.
Click on project and the New Project window opens. Select Visual Basic and choose Windows Forms App(.NET Framework) as shown in the figure below. Also enter the project name and then click OK.
After clicking OK, You will be presented with the Visual Basic 2017 IDE,as shown in the figure below. The VB2017 IDE comprises a windows form, the Solution Explorer, the Properties window and the toolbox.
To start programming, click on the form to bring up the code window.
The first program you can write is to enter the following code:
MsgBox(“Welcome to Visual Basic 2017”)
Running the program will produce a message box that shows the message “Welcome to Visual Basic 2017”
Microsoft has already launched Visual Studio 2017 RC(Release Candidate ) with a gap of one year after launching Visual Studio 2015 RC. Microsoft assures that Visual Studio RC let’s you develop any app on any platform easily.
Visual Studio 2017 RC is equipped with enhancements to code navigation, IntelliSense, refactoring, code fixes, and debugging. It will saves you time and effort on everyday tasks regardless of language or platform.
As we are keen in developing Visual Basic 2017 desktop app, we will focus on .NET desktop development component of Visual Studio 2017. Of course , you are free to explore and try our other development tools of VS 2017 RC.
