Name your TextBoxes with the same beginning text and then affix sequential
numbers after them. For example, names something like this...
ArrayTBox1, ArrayTBox2, ..., ArrayTBox10, ArrayTBox11, etc
Here is simple code to showing you how to use the Controls collection to
address them...
For X = 1 To 12
Controls("ArrayTBox" & X).Value = "TBox Number: " & X
Next
Obviously, the TextBoxes will not be in a "true" array, but you will be able
to address them as if they were.
