Apologies for sending this post in this way - I am only seeing Pauls =
responses on the web-site - has not come through my mailbox yet!
I establish my link to the database with the following code as part of =
the after-init on my first (mainmenu) screen, which is the only entrance =
point for the app :-
ci =3D dConnectInfo(DbType=3D"SQLite", =
Database=3Dos.path.join(self.Application.HomeDirectory, =
"LodgeBooks.db3"))
self.Application.addConnectInfo(ci, "LodgeBooks")
I should mention I originally used the following :-
ci =3D dConnectInfo(DbType=3D"SQLite", Database=3D"LodgeBooks.db3")
self.Application.addConnectInfo(ci, "LodgeBooks")
but changed it to the above to try to ensure I got the right database =
(didn't seem to make any difference).
Within each Bizobj I then get my connection as follows :-
accountsBizobj =3D =
AccountsBizobj(self.Application.getConnectionByName("LodgeBooks"))
accountsBizobj.requery()
self.DataSet =3D accountsBizobj.getDataSet() etc etc

I have done a system wide search for my database file and renamed all =
instances other than the one in my production folder - I still see that =
old data appears if I run my app normally and correct data if I run as =
administrator. I think the answer lies in the 'caching' I have seen =
referred to on some posts on other web sites. Is it possible to force =
the app to run as administrator eg by some entry in the manifest file or =
similar? Alternatively if the 'caching' could be turned off by file ...
Thanks

Further I now find that if I run as administrator the correct data is =
displayed, otherwise it is not. Also, some web searches reveal people =
with similar problems in other programming environments with Vista and =
SQLite where there is a 'shadow' copy of the database ie Vista is =
caching old data somehow. Please - someone out there must have a =
solution for me.
nb will this cause problems for the preferences database in dabo also?

Subject: SQLite and Dabo with Vista
Have a very strange problem which I cannot fathom! I have moved to Vista =
with a new PC recently. Moved all my software environment over (Python =
2.5, Dabo .9 etc etc as was working fine on XP). I have made some =
changes to my system (mainly a new report which required a new Bizobj as =
well). I develop in DrPython using all of the dabo library etc. I can =
run the system OK from within DrPython (I should mention I use a single =
directory for all files - code, database, rfxml etc). I have tested =
everything is working OK and correct data is displayed on reports from =
within my development directory. I have then pumped everything through =
py2exe and innosetup to create an installer. I have initially tested the =
installer on my own machine. Everything installs correctly into a =
directory under Program Files as intended. When I run the app in this =
location I find that the data being displayed is as the database was =
some time earlier, but when I use SQLiteManager to look at the database =
copy in the directory I am running from it shows the latest data. I did =
have a backup copy of the database in an unrelated directory, but I =
have now renamed that, but with no effect. I add a connection to my =
database to the application object at the start of my Mainmenu program =
and all other screens just get the connection by name.=20
I have checked out all the obvious things - any suggestions =
much appreciated!
