How do I use a set of dynamic created textboxes

Hi all.

I thought I was being extremely clever when I created a set of dynamic text boxes on a form.

however, since it's dynamic, I can never know how many are created at runtime. They are labeled txtBoxABC1, txtBoxABC2,txtBoxABC3, etc in the loop.

How can I write a function that detects which of these textboxes is updated, and allows for subsequent processing?

I'm sure this is fairly simple (I can write individual functions but that would be dumb as there may be hundreds), but i don't know how to do this dynamically. Can anybody advise please, or point to a website with this info.

Cheers and Happy Easter!

Yes, it does.

But that doesn't help me, as I do not know how to write the function that takes that into account, which is why I'm asking.

I enter a value into the text boxes. This value is summed against another value.

This is a standard static sub.

The kind of sub I need would apply to one of the dynamically created textboxes.
