 * __OrElse__**

By using OrElse instead of Or in your code it allows a short circuit which allows the program to skip processes it doesn't require. When using If Statements if //**expression1**// is True then it will not evaluate //**expression2**// (as shown in table) which can save a lot of processing time.

//expression1// is ||~ And //expression2// is ||~ The value of //return// is ||
 * ~ If
 * **True** || (not evaluated) || **True** ||
 * **False** || **True** || **True** ||
 * **False** || **False** || **False** ||

As shown in my simple program If **//age1 is >=25//** (True) there is no need to evaluate //**age2**// as the value returned is True and it only needs one expression to be true to continue. If however age1 is <25 (False) then it would evaluate age2 to determine if it is still possible to return a final value of True , once again saving processing time.

This program will display a message box saying "Congratulations you may both enter the nightclub" if either person is over 25

Dim name1, name2 As String Dim age1, age2 As Integer

name1 = InputBox( "Please enter your name", "Name" , "Max" ) age1 = InputBox(name1 & " please enter your age:", "Age" , 20) name2 = InputBox( "Plese enter your name", "Name" , "Cindy" ) age2 = InputBox(name2 & " please enter your age:", "Age" , 25)

If age1 >= 25 OrElse age2 >= 25 Then MessageBox.Show( "Congratulations " & name1 & " and " & name2 & " you may both enter the nightclub!", "Enter" , MessageBoxButtons.OK, MessageBoxIcon.Asterisk) Else MessageBox.Show( "Sorry " & name1 & " and " & name2 & " you can't enter the nightclub", "Entry Denied" , MessageBoxButtons.OK, MessageBoxIcon.Asterisk) End If
