Connecting MS SQL 2000 Thru C++

Sep 6, 2004

Hi,

1)can someone help to explain these 2 lines of codes to me?
I need to change this 2 lines of code to my SQL 2000 database that is connected to my computer locally using Windows NT. How can i change these code?Thanks!

char *connectionString = "dsn=SPS;uid=sa;pwd=;";
hr=pRs->Open(queryString,connectionString,adOpenStatic,adLockOptimistic,adCmdUnknown);

From what i know this is connecting to an instance of the server using sa as login and no password. What does the dns refer to ?

2) If i wan to connect to a database located at the server installed on my computer locally using Windows NT authentication , do i use

"strConnection = _T("Driver={SQL Server};Server=MyServerName;"
"Trusted_Connection=no;"
"Database=SPS;Uid=;Pwd=;");"

If not so,how then?Please kindly advice!

Connecting Oracle To SQL 2000?

Jan 28, 2005

Hi, i need to build some way of connecting Oracle to SQL Server in order to pull data off Oracle and house it temporarily on SQL 2000 for searching.

Basically we've built an intranet using ASP and SQL 2000 and which also pulls data off Oracle, however our connection to Oracle is very slow so an idea to speed it up would be to have SQL store a temporary snapshot of this data and the ASP site query off the fast connection it has to SQL rather than use our slow connection to Oracle.

This temporary snapshot of Oracle data would be stored on SQL 2000 and updated on a scheduled basis.

Any ideas how to do this, or a better way to work this?

Thing is I tried installing the Official Oracle ODBC & Client software on our SQL 2000 server before and it just took out SQL 2000 so would really like to hear other options.

Thanks in advance,

:confused:

Connecting To Northwind On SQL Server 2000

Jan 14, 2004

I've just installed SQL Server 2000 on my local machine. I'm using the following element in my web.config file for my connection string.

<add key="SqlNWind512" value="server=(local)141.705.84.745;database=Northwind;
user id=sa;pwd=h3fe8eq7;packet size=512;" />

Unfortunately, I'm getting the following error on my aspx page:

SQL Server does not exist or access denied.

I had no problem writing a connection string to connect to the MSDE installed on my computer, but making a connection to the Northwind database on my newly installed SQL Server 2000 Developer edition has been elusive to me.

I'm sure my IP address is correct. The authentication mode for logging into the database via Enterprise Manager is setup to require a password for sa. Therefore, I assume it's required in the connection string???

Maybe not so coincidentally, while I have been able to open this database through the Server Explorer in VS.NET, I'm not able to access it via Enterprise Mananger (no response, it just hangs) or my aspx pages.

I'm dying here!!! Is my connection string wrong? Any insights would be greatly appreciated!

Problem With SQL 7 And Windows 2000 - Connecting

Jun 1, 2001

I'm having problem with SQL Server 7 and
Windows 2000. We are deploying an application
made with VB6. This application is multi-users.
Our client has a network of 3 computers. One of
these computers is the server. The application is
deployed on all 3 machines. On the server,
everything goes well. It is possible to connect,
to insert new data, etc. On the 2 other computers,
with the account that installated SQL7 and created
the DB, USER1, there`s no problem at all. With ANY
other account, it is possible to access most of the
application, but some forms would just not access
the DB. We tried to give all rights to all users
on the SQL Server. Nothing. The security used is
Windows NT (2000). There is no rights on tables.
We tried to make a duplicate of the original USER1
account, with all the same rights. It doesn't work
any better.

So all our security is down, and we're still not
accessing with other accounts. We're connecting
SQL Server via the ODBC. I don`t have a clue what
to do next. Please let me know if you have any hints.

Connecting To SQLServer 2000 (sqlsrv32.dll)

Oct 14, 2004

Hello,

I am having problem with our network. We run a clinic database system that uses SQLServer 2000 Enterprise as the backend, and Microsoft Access on the front end.

I have had a running problem with all our newer machines (which run Windows 2000 or XP) in that while it connects to the server and retrieves some of the info properly, on some of the pages it doesnt. It will take 2 or 3 minutes for a page of the database to load, and even then not all the information will be retrieved properly.

I was able to fix the problem on the Windows 2000 machines by replacing the Sqlsrv32.dll file with an older version (usually with 3.70.06.23). And then the W2000 machines would work. But for some reason, the XP machines wont accept the older sqlsrv32.dll file...it gives me this error:
SQLState: 'HY000'
SQL Server Error: 126 Unable to load communication module driver correctly.

....and i cant seem to downgrade the MDAC....

any ideas on what I can do?

thanks

Connecting To SQL Server 2000 On Another Subnet

Jul 23, 2005

Hi Folks,I'm very new to SQL Server. I have a home network. My primary connectionto the internet is using "Gateway 1" a linksys router, of which, my serveris a LAN node on that router. I have another LAN node connecting to the WANnode of the "Gateway 2" a wireless USR router to use with my laptop. Usingthe wireless laptop, I am on a different subnet than the Server. I'd liketo make a connection to the server through Visual Studio.net but I can'tseem to do it. I'm using TCP/IP with a port different than the default port(let's call it port 2110, even though it's not). I do have port forwardingon Gateway1 and I've tried everything from just the server internal IPaddress, the external IP address, IP address with port designation, URL withport designation, nothing seems to work. Any ideas?Thanks!Rick

Issue Connecting To A Remote SQL Server 2000

Mar 11, 2007

I get the following error message in quotes. I have a web application written in ASP.NET 2.0 through which I am trying to connect to a remote SQL Server 2000. My operating system is Windows Vista .
I looked at many different sites to find a solution for this but without any luck. I am sure someone would have seen this issue here and I expect them to shed some light. 
An error has occurred while establishing a connection to the server.  When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server).
The connection string is located in my web.config file which looks like
 <add name="AMSConn" connectionString="Data Source=xxxx;Initial Catalog=testdb;User ID=sa;Password=xxxx" providerName="System.Data.SqlClient" />
I want to get this issue resolved and I need you guys help.
Please let me know if you need any more information.
Thanks

Getting When Connecting To SQL Server 2005 Error Using MS SQL 2000?

Is this a permission setup problem on SQL Server or does it really think it's connecting with a MS SQL 2005 database?
