Always Use Case Else With Select Case

Select Case statements can lead to errors when the test expression in the Select Case line doesn't yield a true result for any of its individual Case expressions. Therefore, you should always use a Case Else as the final Case within a Select Case statement. This sample raises a custom error when an application invokes the Select Case statement with an operation other than the four basic ones:
 
Select Case Operation
	Case "Addition"
		Computer2 = dblNumber1 + _
			dblNumber2
	Case "Subtraction"
		Computer2 = dblNumber1 - _
			dblNumber2
	Case "Multiplication"
		Computer2 = dblNumber1 * _
			dblNumber2
	Case "Division"
		Computer2 = dblNumber1 / _
			dblNumber2
	Case Else
		Err.Raise 1, , "Wrong operation."
End Select
