Does your sql server support sql authentication? It is usually not enabled by default, but must be turned on.

yes it does. i have resolved this Problem by adding a dts config file. The Problem was that the Connection Manager was not saving the Password. so i had to make sure that is there by Explicitly adding it in the config File.
Thank you for your Reply

Hi all,
I used VS2005 with EnumAvailableSqlServers to list all the SQL Server, but when I upgrade to VS Team 2008, EnumAvailableSqlServers does not list SQL 2000 Server in the list.
Imports Microsoft.SqlServer.Management.Smo.SmoApplication
Dim dtServer As DataTable = EnumAvailableSqlServers(False)
Please help me!
Thanks a lot.

Have you upgraded Sql Server as well ?
SMO is changed in Sql Server 2008 
|
|
|
|
|
Not yet, I use SQL Server 2005 Express and SQL Server 2000. Do I have to upgrade my SQL Server to 2008?
|
|
|
|
|
No... Have you taken the proper reference to SMO dll.. Actually if you have, it should be working.
The dlls will only change if you change the Version of Management objects. Check if the reference is kept intact after installing VS 2008.

My VS Team 2008 DVD only have SQL 2005 Express. Thus, I have to buy SQL 2008 or only need SQL 2008 Express?
Thanks.

We use a combination of a user defined function UDF and a table called holidays, this allows us to generate a record set of #n dates and if the date is in the holiday table it is flagged. We use a combination of dayinweek and the holiday table to define processing dates. I am stuck with a Chinese New Year that does not have a fixed date.
|
|
|
|
|
Can you explain in detail, thank you!
|
|
|
|

Do you know what a UDF is and how they function?
Create a UDF that returns a rowset with dates and their state for defined period eg 200 days from 1/10/2009
In the UDF you create a table variable that you populate using the DataAdd function in a while loop
You then update the state based of DayOfWeek function
You then do a join to the holiday table to update the state based on dates entered by the user into the holiday table
(All of the above can be achieved in 1 step but try it in 3 steps to get a feel for the processes)
Return the rowset to the stored proc that called it where it can be used in a join or select statement.

i know UDF is user defined function. but i want to know is the column's type,
for example, monday and 2010.1.0 column's data type,is date? or enum? or others?

This is not a date!

I do not know of an enum column data type in SQL Server
I would have a 2 column table Date datetime and State int or varchar

I cant see anywhere con is initialized... 
try

con = new OleDbConnection(this.connectionString);
con.Open();
rows = cmd.ExecuteNonQuery();
You need to initialize any object before you access any members .  ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

For your use in future posts, this is not really a Database Problem. Your problems are not caused by the database.
You should have posted it in the forum for the language you are using. C# I think in your case.

Inspect your connection object before you call con.open.
Put a breakpoint and debug your application.
|
|
|
|
|
Also put Initialization code above the creation of Command object
query = "INSERT INTO master(RegNo,Name)VALUES(@RegNo,@Name)";
con = new OleDbConnection(connectionstring);
cmd = new OleDbCommand(query, con);
cmd.Parameters.AddWithValue("@RegNo", txtRegNo.Text );
cmd.Parameters.AddWithValue("@Name", txtName.Text );
try
{
con.Open();
rows = cmd.ExecuteNonQuery();
if (rows > 0)
{
MessageBox.Show("records inserted successfully");
}
}
I think it will be working now.

Hi all,
I have a table like :-
Start Time End Time
---------- ---------
12/12/2008 1:46:26 PM 12/12/2008 11:48:06 PM
how can i get the diffrence between these two dates?
(it should be in HH:MM:SS format.....)
Thanks in Advance...
|
|
|
|
|
Start by looking at the DATEDIFF function.
|
|
|
|
|
Here you go.. pretty darn simples.
declare @dt1 as datetime
set @dt1 = '2008-12-12 13:46:26'
declare @dt2 as datetime
set @dt2 = '2008-12-12 23:48:06'
declare @dt3 datetime
set @dt3 = @dt2-@dt1
select CONVERT(VARCHAR(10),@dt3,108)
108 is the format for HH:mi:ss

Mr. J4amieC solution is perfect which will work everywhere.
However, if you are using Sql Server 2008, you can use the new TIME datatype something like this
declare @tbl table(startdate datetime,enddate datetime)
insert into @tbl select '2008-12-12 13:46:26','2008-12-12 23:48:06'
select CAST((select enddate-startdate from @tbl) as time) TimeDiff
