I have a text box where I only want to be able to enter each character once, so no AA or 99, only one of each character. This is so I can paste into the field, but where any duplicates would be eliminated. I've tried using this code, but am not sure where I go wrong.

So basically I'm making a BINGO game on vb 2008 and i have a "call number" button. The letter and numbers get added to a list box each time. But i do not want the same number to be called. Is there a way that the program can read the items in the list box and not generate (Randomly) the same value again to be displayed in the label.This is what i have:
Callnum = Int(75 * Rnd() + 1)
lstNumbersCalled.Items.Add(lblCallLetter.Text & " " & Callnum)

I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.

I know this has to be a very simple answer but I seem to be overlooking it. I have an Access database that I have conected to and have created a DataSet. The DataSet consists of one table with several rows and a bunch of columns. What I am trying to do is get the data for one specific row and column so that I can use this data is some calculations. I can position the row if I need to but I can't figure out how to get the data in the specific column I need.
