IIf

Value = IIf ( Test AS Boolean , TrueExpression , FalseExpression ) Value = If ( Test AS Boolean , TrueExpression , FalseExpression )

Evaluate the Test expression, and return TrueExpression if this expression is TRUE, or FalseExpression if this expression is FALSE.

BE CAREFUL!

Contrary to IF, or the C/Perl ? operator, both TrueExpression and FalseExpression are evaluated, whatever the value of Test is.

Examples

Dim X As Integer = 7
PRINT If((X MOD 2) = 0, "even", "odd") 
odd

' Never do the following in real code, because it is not translatable!
Dim X As Integer = 7
PRINT "You have " & X & " message" & If(X <> 1, "s", "") & " waiting." 
You have 7 messages waiting.

Dim X As Integer = 7
PRINT If((X MOD 2) = 1, "odd", 1 / 0) 
Division by zero
