I wrote a unique error-proof number generator that greatly simplifies the checking of clients’ accountnumbers or other IDs used by your application. I use it in conjunction with the CheckForValid functions.For example, the CheckForValid returns True for number “203931.” The CheckFor Valid returns False fornumber “209331.”
Function CheckForValid(Num As Long) _ As Boolean' Check for valid numberResult = Num Mod 13 If Result <> 0 Then CheckForValid = False ' if false then the number is wrongElse CheckForValid = True 'if true the number is OKEnd IfEnd FunctionFunction Generate(Num As Long) As Long'Generates the successor of a valid 'numberIf CheckForValid(Num) Then Generate = Num + 13 'if valid GenerateElse Generate = -1 ' Otherwise return -1 End IfEnd Function
