.VB files are Visual Basic Source files, which contain Visual Basic (VB) programming source codes. Here is a sample .VB Visual Basic Source file, mapInsert.vb, containing some simple C++ statements:

    Dim StartPos, Counter As Integer
    Dim FindString, ReplaceText As String
    FindString = "test"
    ReplaceText = "MyString"
     
    For Counter = 1 To Len(Text1.Text)
            StartPos = InStr(Text1.Text, FindString)
            If StartPos > 0 Then
                    Text1.SelStart = StartPos - 1
                    Text1.SelLength = Len(FindString)
                    Text1.SelText = "" + ReplaceText
            End If
    Next
