Assuming all your textboxes are prefixed with "txt", you could try something like:
Code:
Dim e As Control
For Each e In Me.Controls
If (TypeOf e Is TextBox) Then
MsgBox e.Name + " = " + e.Text
End If
Next
I haven't used VB in a while, so I don't remember if there's a way to check the type of a control... like "if e is TextBox" (which you can do in .net)
[edit]
NM, Just remembered it. Code above edited for TypeOf
