What is a serial date? Is it a Double, an Integer or what? Does it have a
base date like 1/1/1900? Have a look at the constructors and other members
of the DateTime data type.

In VB6 you could do the following
Dim d As Date
Dim dbSerial As Double
d = Now
dbSerial = d +1
'
' or
'
db = 38793.344780092 6
d = dbSerial
How can I do this in .NET

Have a look at the members of the DateTime data type. For example:
dim d, nextday as date
d = now 'or datetime.now
nextday = d.AddDays(1)
d = DateTime.FromOA Date(38793.3447 800926)
Where do you get the value 38793.344780092 6 from?
Armin
Hi,
AFAIK, An Excel Serial Date is the number of days since 1-1-1900.
For eg., Excel stores March 17, 2006, as serial number 38793 because it
is 38,793 days after January 1, 1900. The digits after the period in
Peter's example are probably the no. of seconds elapsed in that day.
Excel stores dates as sequential serial numbers so that it can perform
calculations on them. Excel stores January 1, 1900, as serial number 1.
But if the members of the DateTime class have any pre-built conversion
defined, of that I'm not too sure. Maybe Armin (Who, I have noticed, is
our DateTime authority... ;-)) can help here.
Regards,
Cerebrus.

Hi, I'm a newbie to programming of any kind. I have posted this to other
groups in a hope to get a response from anyone.
Can any one tell me how to make my VB program read the Bios serial number
(or would HDD be better, or both?) and put that info into VB prog so the
program won't work on another computer. My program uses an MSAccess table.
Much appreciated if you can help!
Thanks

Now perhaps this is a bit dumb, but...
I just populated a new table via \copy. After that, I realize that perhaps is a good thing to have a row identifier in it, so I try
clapidus=> alter table tickets add column rid serial;
NOTICE: ALTER TABLE will create implicit sequence "tickets_rid_seq" for SERIAL column "tickets.rid"

I know that MS Excel converts Dates into serial numbers, but I can't figure

I will be releasing an application shortly which will be used by a few users (less than say 200) but I need a way to protect it and force the user to renew his subscription once his license expires a year after purchasing it.
