XL2000: Visual Basic Example Using If and Case Statements

• Microsoft Excel 2000

SUMMARY

In Microsoft Visual Basic for Applications, there are two statements that you can use to perform a conditional test: an If...Then...Else statement or a Select Case statement. The If...Then...Else statement executes a group of statements based on the value of an expression, and the Select Case statement executes one of several of statements based on the value of an expression.

Sample Macro Using If...Then...Else Statement

   Sub Using_IF()
      ' Dimension the variable.
      Dim x As Integer
      ' Place a value in x.
      x = Int(Rnd * 100)
      ' Display the value of x.
      MsgBox "The value of x is " & x & "."
      ' Test to see if x less than or equal to 10.
      If x <= 10 Then
         ' Display a message box.
         MsgBox "X is <=10"
      ' Test to see if x less than or equal to 40 and greater than 10.
      ElseIf x <= 40 And x > 10 Then
         MsgBox "X is <=40 and > 10"
      ' Test to see if x less than or equal to 70 and greater than 40.
      ElseIf x <= 70 And x > 40 Then
         MsgBox "X is <=70 and > 40"
      ' Test to see if x less than or equal to 100 and greater than 70.
      ElseIf x <= 100 And x > 70 Then
         MsgBox "X is <= 100 and > 70"
      ' If none of the above tests returned true.
      Else
         MsgBox "X does not fall within the range"
      End If
   End Sub
 

Sample Macro Using Select Case Statement

   Sub Using_Case()
      ' Dimension the variable.
      Dim x As Integer
      ' Place a value in x.
      x = Int(Rnd * 100)
      ' Display the value of x.
      MsgBox "The value of x is " & x & "."
      ' Start the Select Case structure.
      Select Case x
         ' Test to see if x less than or equal to 10.
         Case Is <= 10
            ' Display a message box.
            MsgBox "X is <=10"
         ' Test to see if x less than or equal to 40 and greater than 10.
         Case 11 To 40
            MsgBox "X is <=40 and > 10"
         ' Test to see if x less than or equal to 70 and greater than 40.
         Case 41 To 70
            MsgBox "X is <=70 and > 40"
         ' Test to see if x less than or equal to 100 and greater than 70.
         Case 71 To 100
            MsgBox "X is <= 100 and > 70"
         ' If none of the above tests returned true.
         Case Else
            MsgBox "X does not fall within the range"
      End Select
   End Sub
