Visual Basic 2012 code to reference text box with variable

It's all case sensitive.

I'm fairly sure if you do this in vb it's:

lblBox1.Text = "1"

You should read all of this: http://www.vbtutor.net/lesson3.html

I see I poorly described by problem.  I want to select a control by concatenating its root name with a suffix.  

lblBox1.text
lblBox2.text
lblBox3.text
...

This way I can cycle through my controls and change them.
for i = 1 to 10
"lblBox" & Cstr(i).text = "X"
next

Dim cnt As Integer = 1

For Each control As Control In Controls
   If TypeOf control Is Label Then
	   If control.Name = "lblBox" & cnt.ToString() Then
		   control.Text = "X"
                   cnt += 1		   
	   End If
   End If
Next control

Select allOpen in new window

strictly speaking
Container.Controls("lblBox" & strBox1Position).text = "X"

Prefect!  Thanks!
