Multiple Text box

Hi:

    I would like to know how do I do this:

I have 35 textboxes, I need to display string in only 30 boxes ( the rest is for something else).

(I could easily do it using VB6), I think the index properties in VB was not applicable either in VB.net or C# any more. Can some one help me on this?

note: The information to display in the textboxes were actually capture using Serial Port.

Thanks
