How do I represent empty date

[TonyScarpelli]

What is the syntax for representing an empty date?

It seems that ## doesn't work.

Thanks.

DateTime is a value type and therefore can not be empty. I use Date.MinValue for dates like DateLastWithdrawal on a New Acct, or Date.MaxValue for dates, like for DateAcctClosed for an unclosed acct.

In my current FoxPro application, my users have been used to entering dates in certain ways. I have a FoxPro function that formats dates, that the user enters, into a very specific form. For instance if they enter ',' or '.' or '/', it represents today and they see Aug. 2, 2004 on the screen. Also if they enter other formats, they see the same 'Mon. day, year' format in the entry field.

I am turning this FoxPro function into a VB .NET function which returns a 'date' type. If there is an error in the FoxPro function it returns an empty date '{}'. In VB .NET I was trying to also return an empty date which I though would be '##', but I guess not.

I have had to add code that checks for the error and return and empty string '""' instead. I got it to work all right, but it would take less code to just return an empty date type.

Thanks.
