Opened by what, or by whom?
Files can be made read-only or hidden, is that what you want?

Can't you just add a password to the database, use it in your app (through connection string) and not divulge it to the users?
if the connection string is stored somewhere outside the app, make sure to encrypt it, and have your app decrypt it.

Hello!
I have following Microsoft Visual FoxPro expression:
Iif(a, b, ""), where
a = (IsNull(var1), "Z", var1 <> "A")
b = Iif(IsNull(myDate), Replicate("Z", 10), ConvertTimeToCharacter(myDate, 1))
I have divided this expression to "a" and "b" for better readability
I know that statement "a" should return Boolean value, but why "Z" is present there?
Please, could somebody explain me the meaning of statement "a".
I've looking through Internet without any results. 
Thanks in advance!

Should statement 'a' be Iif((IsNull(var1), .F., var1 <> "A"))?
As it stands it does not make sense, (IsNull(var1), "Z", var1 <> "A") is not a statement.

hi
I have datarow which contains an int column
I want to increase the value by 1:
(int)row[0][0] += 1 // the first column is an int field
but when I do this I get an error: "The left-hand side of an assignment must be a variable, property or indexer"
is there a way to do this?

What database, what language, are you using the CLR.
If you are using SQL then you need to learn the language, it is not C#. Thats why they invented linq - to get you poor sods a language you knew.

Don't you want to understand why you get this error?
You have cast the left side to an int meaning the left side is no longer the indexer.
You could probably write
row[0][0] = ((int)row[0][0]) + 1;
But, since I don't use DataSets it may or may not work.

Hello
10g Express + ODP.NET (version 2.111.6.20) > support TransactionScope?
I read ODP.NET doc it does support .NET TransactionScope
But what about 10g Express database? My application died silently (i.e. just exit, no exception) on first db call - and if I just comment out TransactionScope, object instance get saved successfully.
Just found out there isn't an "Express" version for 11g? What should I be using...?
Thanks

this works ok in sql server
<br />
SELECT MessageID, LEFT(Message, 80) AS Expr1<br />
FROM MSGTble<br />
but when i try to do it through stored procedure, my webform is giving me error
<br />
ALTER PROCEDURE dbo.GetAllMessage<br />
AS<br />
SELECT MessageID, LEFT(Message, 80) AS Expr1<br />
FROM MSGTble<br />
RETURN<br />
saying "A field or property with the name 'Message' was not found on the selected data source."

Remove the RETURN from your store proc.

Hi,
if the column is not there you should get the error as invalid column.
Try to execute the procedure within sql query analyzer window and check whether it returns any value correctly.
In the query analyzer window you have to type the procedure name and excute it and see.
It looks to me this could be coding problem on your webform.

Its because you don't have a column called Message in your select statement, you alias it to Expr1, and I expect in your code you are referring to a column called Message.

Hello Friends
What should be the query to show or find duplicate rows in a table?
Thanking in advance
Johnny

One way is to group by every column, so if you table has four columns, this would do the trick:
select col1, col2, col3, col4 from MyTable
group by col1, col2, col3, col4 having count(1) > 1

hi,
I have written a cursor that goes into infinite loop. I am not able to make out where i have done wrong.

/******************************************************************************/
declare @dirid int
declare @topic varchar(8000)
create table #topic(Dir_Id int,topic_Id varchar(1000))
insert into #topic(Dir_Id,topic_Id)select D.Dir_Id,D.topicid FROM Category CN
INNER JOIN directory D ON CN.Cat_Id = D.OrgType_Id
INNER JOIN SubCategory SB ON D.Country = SB.SubCat_ID
WHERE CN.Cat_Name = 'Academic'
declare curtopic cursor for
select Dir_Id,topic_Id from #topic
open curtopic
fetch next from curtopic into @dirid,@topic
begin
while @@fetch_status = 0
set @topic = ''
SELECT @topic = topic_Id from #topic
fetch next from curtopic into @dirid,@topic
end
close curtopic
deallocate curtopic
print @topic
drop table #topic
/****************************************************************************/
i want to retrieve the data row by row for which i have written cursor.
but it is going in to infinite loop.
any help would be great full.
regards,
pranav

There you have it - that's the loop that executes. You need to put the statements in a block using begin and end.

I want to know if SQL Server 2005 has predictive analysis tools?
http://www.microsoft.com/sql/technologies/dm/TATForecast/TATForecast.html
In above link you can see how Office 2007 has this Forcast feature using the analysis services(2008 i think). Can such a thing be done in VS 2005/2008 or SQL Server Business Intelligence Development Studio 2005
If yes, then can you point me to some useful links or demos.
If it cannot be done in SQL server 2005, but can be done in SQL server 2008( which i think it can be) then please give some useful links and demo for same.
Thanx,
s.a.w
