Date Value Not Valid
Posted: Fri 26 Aug 2011 00:21
Hi,
I have a simple program that goes and retrieves a date value from an SQL Table. On my machine (Win 7 64 bit) it works fine and returns the following:
Returned Str: 15/08/2011
Returned Float: 40770
Returned Formated: 15/08/2011
When I run it on a newly installed (Win 7 32 bit) machine it fails with an Date is not Valid error:
Returned Str: 2011-08-15
Returned Float: Error!
Returned Formated: Error!
Now I can see that the date is not formatted in the correct way but when I check the following details they are both the same.
Date Short: d/MM/yyyy
Date Long: dddd, d MMMM yyyy
Date Separator: /
DefaultLCID = 00000C09
PriLangID = 00000009
SubLangID = 00000003
FarEast = False
MiddleEast = True
Why is the returned date not formated correctly on one computer but is on the other? If I format todays date using the now function all is correct.
Below is the sample code.
I have tried it on several other computers and they all work, can anybody try an shed some light on this for me.
I am using Delphi 6 and Delphi 2007 with SDAC Professional Version 5.10.0.8
Thanks
Duncan
