as the demo shows in page 60 i'm trying to add the line:
MessageBox.Show(dteResaults.ToLongDateString, "Date Demo")

however ToLongDateString function doesn't appear to be valid. neither is ToShortDateString.

any ideas ?

Well, ToLongDateString is a *method*, so it should be followed by parentheses.

But more than likely the problem is that your dteResaults is not a DATETIME variable. (By the way, is it simply a case that you spelled it wrong? I would have expected the name to be dteResults.)

i defined dteResaults as string.
thanks
