Date from DoubleHello,
In SQL, if I do Select cast (37797.8159722222 as datetime)as DateFromDecimal i get 2003-06-27 19:34:59.997 as the return. in VB.NET if I do: Dim idate As Date idate = Date.FromOADate(37797.8159722222) I get 6/25/2003 7:35:00 PM as the return. Any idea as to why I'm getting different day of the month? Any idea how I can get vb.net to return the time in the same precision as SQL? VB.net appears to be rounding the time up to 7:35:00 PM Thanks! 1. An SQL DateTime is not an Automation date (the difference is 2 days),
so to correct for this, add 2 to the double value in VB before converting it. 2. An SQL DateTime has a precision in milliseconds, VB in seconds, so, the rounding you mention is correct. a VB datetime is stored completely differently than SQL DateTimes, so, stored as a double rushaus***@gmail.com wrote: Show quoteHide quote > Hello, > In SQL, if I do > Select cast (37797.8159722222 as datetime)as DateFromDecimal > i get 2003-06-27 19:34:59.997 as the return. > > in VB.NET if I do: > Dim idate As Date > idate = Date.FromOADate(37797.8159722222) > I get 6/25/2003 7:35:00 PM as the return. > > > Any idea as to why I'm getting different day of the month? > > Any idea how I can get vb.net to return the time in the same precision > as SQL?
