Question

I need to do some validation in classic asp on some user-supplied strings to make sure they are valid dates. How can I parse the string to a date while checking for type mismatch exceptions…

So far it’s looking alot harder than I thought!

Answer 1

You can use IsDate for this.

This determines whether the value is a date or can be converted to a date.

E.g. (from here),

x = "January 12, 2009"
if IsDate(x) then
    msgbox(CDate(x))
end if

Output:

1/12/2009
