We can create a Asc to Chr and Chr to Asc converter in VB. Let’s examine the following Example:

In this example, we create two buttons, label one of them as ASC and the other one as CHR. Insert two textboxes, one for the user to enter an ASC code and the other one to enter the CHR character. When the user enter an ASC code, he or she can check for the corresponding character by clicking the CHR button. Likewise, he or she can check the corresponding ASC code after entering a character.

The Code

Private Sub CmdASC_Click()
TxtASC.Text = Asc(TxtCHR.Text)
End Sub

Private Sub CmdCHR_Click()
TxtCHR.Text = Chr(TxtASC.Text)
End Sub

Please refer to the following article for more details.

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:

Dim myArray()

Then at run time we can specify the actual array size using the ReDim statement,as follows:

ReDim myArray(n)
* 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.
