I'm trying to write a Database manager in VB (2010) that updates a SQL database that compiles and summarizes my financial records. The code works, but I'm having issues with one exception that I think I understand, but can't circumvent. I've built an I/O form that enters a series of purchases and sales into a temporary datatable. After review of the list, the program connects to the database and executes the SQL. That all works and isn't a problem.

In my winform program (in vb.net) I wrote:
Dim dt As New DataTable
'Get data from DB into dt
'...
[Code].....

(I finally found a solution - dttemp = dt.Copy() instead of dttemp = dt. But I still can't see why Copy() was necessary in this case.

The code concerned is below:[code]Basically, I only want to allow numbers in the text box. When I enter a letter for example, the message comes up ok, but then when the box is clicked away, the rogue letter remains. Can someone tell me how to clear it properly?Also, when I use the backspace button in the box (pretend I want to change my input from 3 to 37), then the messagebox is prompted when I don't want it to be.

2) How do I get VB to ignore any backspace presses to prevent the messagebox from coming up.
