hrmm, this is a little open-ended. What type of animation are you referring to? Does the animation relate to events in the application? Need more info to advise.

Well, to clarify further, you would re-verify the validity of the field, and if it was ok then you would "SetError" to ""

you have to clear the Error String via SetError:

errProvider.SetError (this, ""); //clear error string, icon hides

Java time represents milliseconds since January 1, 1970, so if you account for that date instead of the January 1601 date, you should be OK.

long tm = 1217404627332;

DateTime dt = new DateTime(1970,1,1,0,0,0);
dt = dt.AddMilliseconds(tm);
MessageBox.Show("Time: " + dt.ToLongDateString());

HTH - although I get Wednesday July 30,2008....closer! -curtisk
