How can I refer to controls with a variable.E.g. I want to set the 'left' property of six text boxes to 100. Rather than type "text1.text = 100" for each (changing the number), how can I use one line in a repeat loop, where the number '1' in the above example is a variable that changes?

For i = 1 To (Form1.Controls.Count - 1)
    If TypeOf Form1.Controls(i) Is TextBox Then
        Form1.Controls(i).Left = "100"
    End If
Next

Now, this will change all text boxes on your form. If that won't work for you, you'll have to put an extra check like this:

For i = 1 To (Form1.Controls.Count - 1)
    If TypeOf Form1.Controls(i) Is TextBox Then
        If Form1.Controls(i).Name = "Text1" or "Text2" Then
             Form1.Controls(i).Left = "100"
        End If
    End If
Next

Make a control array of text boxes:
So name all the text boxes "MyText" and set the index property to 0,1,2,3,4,5 etc
Now use a for loop
--
Dim t as textbox
for each t in MyText
   t.text = 100
next
--
or
--
for i = 0 to 6
   MyText(i).text = 100
next

Oops...made a mistake. That loop should start out with:

For i = 0 To (Form1.Controls.Count - 1)
