I am trying to create a "listbox" that is fed by data entered from 3 "textbox" but when I press the button, no results appear in the "listbox", and I get the following error:

BC30188 Visual Basic Declaration expected.

VB

Public Class Form1
    Private i As Object

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        'Declarar variable
        Dim contador(i) As Integer
        Dim Valinicial, ValFinal, ValRepetir As Integer
        'Iniciar variables
        Valinicial = dato1.Text
        ValFinal = dato3.Text
        ValRepetir = dato2.Text

        For i = Valinicial To CInt(ValFinal) Step ValRepetir
            i = dato1.Text * dato3.Text

        Next
        For i = Valinicial To ValFinal

Perhaps "CInt" has not been declared (Dim) as type integer?

Dim CInt As Integer (add it to contador(i) As Integer) to make a list.

[EDIT}
You know, when you edit a post to conform to something a qa answerer says, you make it difficult for anyone with postential HELP to follow you; unless you use something like what I'm using here in this comment -> an "[EDIT]" message addition mark. You could also use the REPLY widget to respond directly to .. whoever. Just a heads-up for future readability.

Ha declarado i como un objeto al principio de la clase, y luego está utilizando i una vez más como el iterador de un bucle for-next

(You have declared i as an object early in the class, and then you are using i once again as the iterator of a for-next loop)

VB

Public Class Form1
  Private i As Object

  Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    'irrelevant code
    For i = Valinicial To CInt(ValFinal) Step ValRepetir
      i = dato1.Text * dato3.Text
    Next
