Tcp/ip Connection
I'm trying to maintain a permanent tcp/ip connection between two
computers using ASP. I need users accessing the ASP pages to be able
to send and receive messages using this connection. I know that I
can't use a Winsock control with ASP so I guess I'm looking at a third
party control. Even if I can get this working I'm not sure that I can
have different users accessing this one permanently open connection.
I've looked all over the Net for ideas on how to do this but I've had
no luck. Has anyone had to do anything like this?

1.
conn.ConnectionTimeout = 60
conn.Open connString
2.
conn.Open connString
conn.ConnectionTimeout = 60
Do both of them give different?

I wanted to know wheather DSN is ok for the connection to a database or direct conection is better?
when i started my web project on dreamweaver i had to make a DSN connection as i have followed the books, but as now as i have also asked several questions on this site, i have aslo implemented a direct connection as well on some pages, now i am wondering
is this going to have any affects when i uplode the complete site on the server.
i have noticed that on my computer when i am testing the site and uploading new records on sections that have DSN connections you can see the new record but on sections that i have implemented direct connection i cannot see it coz it is linked to the local directory database not on the testing server.
i have also never experienced uploading to a IIS server with DB connection so its my first time with dynamic websites. so am i in trouble or its ok the way i have done my site..

When I click submit after updating the information all of my info gets deleted from the db so I'm guessing that the values that are being submitted are not getting picked up in the sql. I've tried changing the form names, etc, but still have the same prob. My code is below: Code:

I'm using an SQL2K backend and attempting to connect to it with the following code.
' -- Connection String Value
response.write "Setting strConnection"
strConnection = "DSN=tracktimedb"
' -- Our SQL Statement
response.write "Declaring SQL Statement"
strSQL = "SELECT * FROM TIMES"
' -- Populate our Recordset with data
Set objRS = GetRecordset(strConnection, strSQL)
I have done many searches but all the connection strings I've found seem to be using a DSN to an access DB. Currently I get this error when trying to connect.
Microsoft OLE DB Provider for ODBC Drivers error '80040e4d'
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
I can't seem to find the proper syntax to specify a db login (sa) and password in the connection string.

on 1 page i open
a connection to a database and build a recordset to check
username and password. there are other fields in the db
that i need to access on the next page. how do i reference that
connection and run a new sql query without having to reopen the connection?
i thought it would be as simple as NOT closing it, but thats not working.

I am having problem in my connection to database when running ASP.
It works fine for the first time but if I run it again without a gap of atleast a minute,
it gives me the following error message:
Error Type:
Provider (0x80004005)
Unspecified error
And the line it is showing error is where I am opening my database connection using conn.open.If I wait for couple of minutes and run again,it works fine.

I am getting 500 Internal Server Error. I have tried disabling the show
friendly error in IE and I have tried it on Firefox. It will not give me the
reason why it will not work, I only get 500 Internal Server Error.
I have tested the code up to the point of Set objConn and it works but when it gets
to the objConn.open dsn that's when I get the error. I wish to find out why
it is not allowing it to get pass this point. I have control of the server
where this is hosted and if there is anything I need to do, I can do it.

I am trying to create a web page on our company intranet.I am using Frontpage 2000.I need to be able to read from and write to databases in this project.I am starting slow since I am just learning, so for now I am trying to read from an existing SQL database on a network server. The server is running SQL Server 2000 and IIS.
I could create a database connection using the Database Results Wizard in FP. The connection would verify OK and I could select the columns from the table I wanted to display. When I published the page to the server, all I got was column headings, no data.
when I try to create a new db connection, it will verify, but it will not show up as an existing db connection.

I have a client Gallery i am setting up for clients to view and approve their work online in their private area, the database is set up the way i want it, and the site has been set up as an individual site (Gallery only) which i will then transfer onto the backend of my site.... (client entry)
But i want to be able to just copy the whole folder Client Gallery mentioned above) into a new subfolder for a new client and continue to do so for each client, so they will be able to view their work without me having to change anything in my ASP pages every time i get a new client, the database uses a link to the images & their not stored directly in Access.
if i use the same database and DNS but its in a different folder along with its gallery script and script pages it uses, will it only refer to that new folder its in and folders following or will it search the whole directoy within the site and get confused due to the same database connection with different images or different linked folders.

I am using:
Set dbConn= Server.CreateObject("ADODB.Connection")
dbConn.Open "DSN=somedsn; UID=someuser; PWD=somepassword"
To (try) to connect to an Oracle DB: ASP 'hangs' in the dbConn.Open statement if a valid connection string is supplied. If an invalid string is supplied (e.g., the DSN doesn't exist), the dbConn.Open statement returns immediately, with appropriate error messages.
If connection is attempted outside of the IIS environment (e.g., by some other VB application) using the same connection methods, no problems are encountered. I tried both ODBC or OLEDB, it does not work at all.

I need to create some .asp pages to publish data from our manufacturing lines...but I can't figure out how to establish the connection string and print the data. I've been stuck on this all day and about to start pulling my hair out!!!
As an example, can someone create the most basic code necessary to build a web page that does the following:
a) connect to a SQL version of the Northwind db (assume I have a functioning ODBC connection called 'Northwind_ODBC' on a server called 'ProductionServer')
b) Loop through the records in the [Shippers] table and paste the values in a HTML table (using SELECT * FROM SHIPPERS)
I know it sounds simple but I'm looking through some books and can't find a solution that works on my server.
NOTE: I'm running Server 2003 (with IIS), SQL Server 2000, and I have proven ASP does work on this machine...unfortunately, just not with the code I'm trying to build!!!

I was wondering if i can create an if/else statement that checks if my connection string that opens a database ie:
cnnDB.Open Application.Contents.Item("CONNECTION_STRING" )
(the actuall connection string is in my global.asa file incase u were wondering) ...or if the database can't be found or opened, will run some other code... like a message?
hope u get what i mean.
this is just incase a user has the DB opened, or is in the process of overiting the DB or something, the page would not display that Microsoft JET Database Engineerror but display a message i set up in the if/else statement.

I created a ADODB.Connection object in Session On_Start and tried to connect to the databse On_Start. It is giving errors. Can't have a connection opened only once in a whole applicatio like VB.
The Con variable is available for the whole session but the connection state is not available for the whole session. Do I need to open a connection everytime I want to access a database????

well I'm not sure how to go about making my SQL connection string...
The code below is what I need to replace with my SQL connection...I
just don't know if that code is for DSN or access...
I don't want to use DSN just a connection string.
function GetConnection()
const DSN = "membershipdb"
const UID = "webuser"
const PASSWORD = "password"
Dim p_oConn, sDSN
Set p_oConn = server.createObject("ADODB.Connection")
sDSN = "DSN=" & DSN & ";uid=" & UID & ";password=" & PASSWORD
p_oConn.open sDSN
Set GetConnection = p_oConn
end function
