Hi
I have created a Visual Basic application the connects to my SQL database.
The appliction lets a user click on a button, data is retrieved from the database
and then formatted in Excel. Everything works fine on my machine (this is probably
because i have both VB and SQL installed on my machine)
I have created a .exe and deployed the application on some users desktops. The
problem is that when they click on a button - nothing happens. I dont even get any
error messages! Everything else appears to be fine. I have tested the DSNs and
they appear to be fine too.
Does anyone know why this would happen ??
Thanks, Ruaidhri.

Whenever a user logs on to SQL-Server there´s
a message in the application log of windows NT
like
"Login succeeded for user 'Domainusername'. Connection: Trusted."
Since we have lots of users. The application log fills up twice a day.
Is there any way to prevent SQL-Server from doing this ?
(I know that there are settings in the event-viewer which clear events
whenever space is needed).
Thanks.

I'm not sure if this is the right section for the question, but here goes...
I have an application that needs to be run in network client mode. This app is supposed to connect to a SQL 2005 db hosted on a server. As I procede through the installation process I get a prompt when i populate the serverdb information.
'The listener port was responsice, but did not return a primary port number for <servername>. Please verify that <servername> is a valid and running database before proceeding.
A little background is in order:
Host:
Server 2003 Standard
SQL Server 2005
Installed instance of said db
Client:
Windows XP Pro sp2
Network config:
We have a domain with about 125 workstationslaptops. Windows firewall is turned off using a group policy (makes it easier to push apps out to clients). For giggles I made exceptions to the 'turned off' firewall policies for the needed ports etc. This was done on both the host server and the client.
Thank you in advance.

Hi there
Can anyone point me to a good tutorial or give me a run down on using Sql Application roles from my asp.net application. Books Online only give a run down on how to set it up - not how to implement or use it from my code. MSDN no help. Google - same thing.
Any help greatly appreciated.

hi
I have completed a windows db app.
I have saved the db files in the application/bin/ folder.
The connectionstring that i am using is
Code:
sql
Server =(local);Data Source=.SQLEXPRESS;DataBase=;Integrated Security=SSPI
say i wanted to install this app on my home computer, does not have sql express or anything installed.
Now i want to use the application and it must read/write data from the sql db that was saved in the application/bin/ folder.
what is the connectionstring then ?
can anyone please help ?
what im trying to say is that the application must work independent from any SQL manager/express etc.
is that possible ?

Hello,
For my application, I need to consult a database located on a server on the local network. The application is located on my pc. I use the connection string
Code:
"Integrated Security = SSPI;database=dbName;data source=serverName"
(I program in C# and connect with ADO.NET)
When I compile my project as a windows application, this works fine. But when I compile as a web application in ASP.NET and try the same connection, it won't connect. How can this be solved?
Thanks

Hi everybody,
Here the environment is application in 3 layers.
So the user in his client machine, access the application in an application server that sends the request to my sql server database server.
My problem is: when I run sp_who from Query Analyzer, I see the host name that is pre-defined inside code application. But, actually, I need to know the user who is requesting the transactio so I can know right the person who is slowing my database performance....
Do you know, any function, procedure or anything else that I can use in the application code in order to provide the user or the host name from the client machine?????
I hope some answers...
Thank you all,

If I have a web site accessing SQL VIA IIS will SQL Server treat it as an application ? How about MS Excel ?
Also , If I was to use the application of Power builder , using app role , how do control which user can use the app ?

Hello Friends,
A user is calling stating that their application is hung - sitting with an hour glass or with the browser not responding. Assume you know the server and the instance and that the server supports multiple instances.
You need to determine if the database could be contributing to the problem or could be the cause of the problem. Describe at a high level what process you would follow to rule the database out or in as the problem.
Any idea!
Thanks,
Frank

Hello everybody,
I'm a new commer. I'm happy to join dbForum with all of you. :beer:
I'm coding a DTS application for my company's data mart. And it's the first time I code a data movement application in .NET. I use SQL2000sp2 Personal Edition for datawarehouse and WinXPsp Professional.
I have looked around the site http://www.sqldts.com/default.aspx?225 and regst.txt in the SQL-CD to reference DTS.dlls as below:
INSTALLATION NOTES FOR DATA TRANSFORMATION SERVICES (DTS)
---------------------------------------------------------
The following files must be registered using the regsvr32.exe utility:
dtsffile.dll
dtspkg.dll
dtspump.dll
axscphst.dll
Example: regsvr32 80ToolsBinndtsffile.dll
The sqlunirl.dll file should reside in the system folder (i.e., winntsystem32 or windowssystem).
I added other dll references successfully but sqlunirl.dll. And I recieve the err:
"C:WINDOWSsystem32sqlunirl.dll" was loaded, but the DllRegisterServer entry point was not found. This file can not be registered." :eek:
As I run my application, it also fire an unhandled exception like this:
"Unable to cast COM object of type 'System.__ComObject' to Interface type 'DTS.CustomTask'. This operation failed because the QueryInterface call the COM component for the Interface with IID
'{10020904-EB1C-11CF-AE6E-00AA004A34D5}' failed due to the following error: No such interface supported (Exception from HRESULT:0x80004002(E_NOINTERFACE))" :o

We are rolling out mssqlxpress to our development staff and would prefer to alter their permissions so that they can only make changes using mssqlxpress (since it integrates nicely with VSS).
So are choices are to uninstall SQL Enterprise Manager and SQL Query Analyzer, or more preferably, alter their NT Permissions so that they do not have the capability to change anything in the DB's.
My concern is that it seems we can only set their permissions from DB level and not the application, does that sound correct? Has anyone else had to deal with this predicament and is there an alternative to uninstalling the SQL Client tools?

Please correct me if I'm wrong, but isn't it bad parctice to place multiple applications in the sam db. My SA wants me to use the same db for all of the apps I develop and then just name the tables accordingly. Can someone please give more insight on why this is bad, and my chances for doing it right the first time will be better. Thanks.
