I just started getting this message on 5/4/05! I'm not parsing and before
this, my program worked just fine. Here's a posting I put on another site
in desparation:
Greetings,
I don't know how long ago this conversation took place, but am desperate
for help with the same problem. Up until two days ago, my code for
inserting a record into a table worked fine. Update still works, but on
insert, I am getting this dialog box now:
System.FormatException: The string was not recognized as a valid DateTime.
There is a unknown word starting at index 0
It's driving me crazy. Mostly because this has worked fine until now.
There are four dates (though I removed TimeStamp to try to fix) and I have
tried everything!
One important thing to note is that my product is completely in English,
having nothing to do with other timezones or anything like that.
Anyway, I don't know if anyone can (or has time to) help. Just thought I'd
try and ask.
Carolyn
