Is there a way for displaying a default value such as a dash "-" for datetime values in custom objects?  

For example, say I have a Widget with a DateLastAccessed property of type datetime and upon creation of the object I do not have a date for DateLastAccessed.  How might I display "-" in place of this value in Salesforce?

Some background, I am using .net and the partner wsdl.

Thank you.

Anyone ever receive this error before?

The full error is "Web service callout failed: Unable to find Apex package for Knotice:ervice"

I have an apex class that I created from a wsdl.  I've already verified that the web service is working fine, it's just puking when I try to use the apex class.  

Thank you,

Matti
