IsNumeric(expression)

The expression argument can be any expression.

IsNumeric returns True if the entire expression is recognized as a number; otherwise, it returns False. IsNumeric returns False if expression is a date expression.

Dim MyVar, MyCheck
MyVar = 53   ' Assign a value.
MyCheck = IsNumeric(MyVar)   ' Returns True.
MyVar = "459.95"   ' Assign a value.
MyCheck = IsNumeric(MyVar)   ' Returns True.
MyVar = "45 Help"   ' Assign a value.
MyCheck = IsNumeric(MyVar)   ' Returns False.
