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.

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following sample macros show how to use the If...Then...Else and the Select Case statements.
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)
' 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)
' 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
