Answer 1

You have to draw FIVE textboxes and ONE button on the form
(1) Declare a Collection at class level,
(2) In Form_Load event, add your textboxes to the Collection
(3) You can access all your textboxes with for loop as shown in following code
Dim AL As New Collection
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
AL.Add(TextBox1)
AL.Add(TextBox2)
AL.Add(TextBox3)
AL.Add(TextBox4)
AL.Add(TextBox5)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer
For i = 1 To AL.Count
AL(i).Text = "Hello"
Next
End Sub

First create a list of the number of textboxes you want to modify and name the textboxes in a good way
--> Exemple :
-----> I have three textboxes names as following : " ttttaksa1" , "asiuhi2" , "EEFUGUYug3"
-----> We have put a number at the end of the textbox so we can call mofidy each one
according to its number
-----> Now that we have 3 textboxes , we will make a list of strings with the numbers of our textboxes : in this case : 3 numbers ( NB : The list is of STRINGS ! )
The list will be like that : Dim n as New List(of string)=({"1","2","3"})
if we have 11 textboxes for exemple it will be like that :
Dim n as New List(of string)=({"1","2","3","4","5","6","7","8","9","10","11"})
Now , if you want to , for exemple , change the text of the two first textboxes (ttttaska1 and asiuhi2 ) , you will need to do that :
For Each textbox In Me.Controls
For Each s As String In n
If textbox.Name.ToString.EndsWith(n) Then
'Do what you want to your textbox ex : textbox.text="Anel"
textbox.forecolor=Color.Blue
End If
Next

Dim textBoxTemp As TextBox
Dim stringData As String
For index = 0 To 23
stringData = ("txtBoxReal" & index)
textBoxTemp = CType(Me.Controls(stringData), TextBox)
textBoxTemp.Text = 0
Next
