Is there a way to repeat two popup input boxes (in succession) until the user presses cancel?
Dim hours As Integer
Dim letterGrade As String
Do

How would I cancel a Search? I understand that I would have to run the Search on a separate Thread. Would I just abort the Thread? Or do I need to send SQL Server something to let it know that it can cancel the query?
