I have a data base that I use ADO primarly to connect to the backend access database. Each time I query a table I create a new connection and then kill the connection after I'm done with it. Should I be creating a global connection and leave open the entire time the program is open, or should I be killing the connection each time?
View RepliesDear Guys,
How to Establish the connection between Ms-Access2000 & Oracle using DAO Connection through Code?.
I created one table in Oracle and I created User-DSN in ODBC.
I linked that oracle table into Ms-Access MDB using Link table option in ms-Access.
Now, Whenever I open that mdb, we need to establish the ODBC connectivity automatically through code (I mean, we need to refresh automatically).
I need to hardcode all the information in the Ms-Access code.
My User DSN Name: abcd
Oracle Database Name: abcd
Schema Name(User Name): abcd
password: abcd
Right Ok i hope i can get some help cause im absolutely stumped..
i cant get my login page to work since moving it from my PWS(iis on xp) DSN connection
to a 24/7 server on the net with DSNless connection
here is the code for the include file "conntopwd.asp"
http://www.pritchardwebdesign.pwp.blueyonder.co.uk/conntopwd.txt
the username and path has been changed slightly for security purposes,
and the code for the login page which attempts to access the database is here
http://www.pritchardwebdesign.pwp.blueyonder.co.uk/login.txt
the connection has been tested by one of the tech support guys at brinkster and he told me it was ok,
the problem was the way that the data is called from the data base is wrong ..
The tech support guy said that it was this line that was causing the problem..
MM_rsUser.ActiveConnection = MM_conntopwd_STRING
Any help would be much appreciated as im stuck for now..
Is it possible to connect access data project with two or more sql databases?
Thank you
I simply want to create a connection to an Access db, and run an execute an SQL statement.
I have only used RecordSets in the past, so this ADO.NET is completely new to me.
Can someone give me a sample code to execute an SQL statement, and take the result and assign it to a string variable?
I can bind my results to a DataGrid, but if I need it in a string, what good does that do me???
Also, I am only familiar with VB, but if someone has to post it in C#, I'm sure I can figure it out! I appreciate any help.
hi everyone;
I'm trying to make an ADO connection to my local database named "dbTest.mdb".
Here is the code I'm writing in my editor:
Code: <body> <% Set CN =server.CreateObject("ADODB.Connection") CN.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:InetpubwwwrootNew FolderdatadbTest.mdb;Persist Security Info=False" Set RS =server.CreateObject("ADODB.Recordset") Set RS.ActiveConnection = CN RS.Source = "select * from tblTest" RS.CursorLocation = adUseServer RS.CursorType = adOpenKeyset RS.LockType = adLockOptimistic RS.Open response.Write(RS.fields(0)) RS.close Set RS=Nothing %> </body>
and this error comes up in my browser:
Code: Error Type: ADODB.Recordset (0x800A0BB9) Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another. whats the problem with my code???!!
Good Morning,
Rookie Alert ! I am trying to incorporate simple Access database to web page. In page one, I use Database Results Wizard to display records in database. I pass parameter (last name) via hyperlink to second web page to view complete record. I always get no records found. When I asked tech support, they sent me this:
We do not have registered DSN's on the host server. You will need to use a DSN-less connection string using an absolute path to the file. The path to your account is c:accountsusername and from there you would add the path to the db within your home directory, I.E. -
"Driver={Microsoft Access Driver (*.mdb)};Dbq=c:accountsusernamewwwRootmydataba se.mdb;Uid=Admin;Pwd=;"
I have seen other references to this and I have tried what they said with no luck. Where in the page code would I put this? I am using Frontpage 2003. Any suggestions would be helpful or a working example would be nice.
To look at what I am doing, go to test page:
www.adjustertraining.net/searchresume1.asp
Thanks in advance.
I will create an Access application as a Front end application. The matter is that the users will need to update some data from Internet where there is a MySql server.
I thought in creating a local DSN to connect to that MySql server. Is it right ?
I already created it but... I dont know the code to connect it from Access.
Could you please help me with the code to write in Access ? Im a new with it. sorry.
Or you can send me an example of it in an Access database to: osvaldo@ord.com.ar
Thank you very much
Osvaldo
Hi Everybody!
I am creating an Access database that will be used by multiple users. This database will be on the network and will be the front end of an oracle database connected to it via ODBC. Do I have to set up the ODBC to oracle only on the machine that hold the database on the network or do I have to set up an ODBC on each user's machine?
Thank you for your help.
hi all,
i'm create a aplication in ms access 2000 developer edition. this app comunicate with sql 2000.
we have problem with slow connection provided by access. in headquater wher people use access app it working quickly. sql 2000 is localted at headquarter too. but if i run app in warehouse it working very slowly.
VPN connection doesn't slow. but access can't use all vpn connection capacity but only 1/5 from this capacity?
how can i do something that acces can use all capacity that i have?
example: link is 512 kbps but access use only 100kbps and work very slowly.
I have a small access database that my users keep open all day long. Access 2000.
I have one primary version of the DB on the network. No one uses it. I have another file on the network that has linked tables to the primary db. I copy a version of this DB to each workstation.
So each user has a full blown DB on their desktop with linked tables back to the main DB. Is this a good set up or are there any issues doing this? What is the best set up for multiple users across the network? Thanks.
Hi There
one another database have started showing a new error
"the database has been placed in state by user 'Admin' on machine 'XXXXXX' that prevents it from being opened."
I read some of the articles on google and find out tht database splitting is solution for this.
Now my question is if after splitting i keep the front end and back end at the same location does it gonna effct some how?
i mean even after spliting if users use the same copy of database as fromt end. Does it make some sense.
Thanks

Hi all,
I have an .adp that works fine on a number of people's laptops.
One of the users however, keeps getting an error message stating that SQL Server does not exist or access has been denied.
This particular user is definitely setup on SQL Server with dbo permissions. She can also ping the server.
I have tried creating a DSN and this doesn't work either.
I am at a loss as to why this error message is occurring given that she can see the Server and has definitely been setup.
Do you have any suggestions?
Thanks,
Kabir
Hi,
I know (and use) the code for using a DSN already setup on a user's PC.
But, does anyone know how do it it without the DSN alredy setup in VBA to an Oracle db?
Many thanks.
Hello...
Question, do you need one for your database and if so why? I have read what they are but I haven't found really why you would need it?
Don't know if this is the right place to post this question but wanted to get some input on this.
Thanks

Hi i would like to make a question about ODBC i have created an access database that connects via ODBC to an SQL server database, with the help of someone else i have created this code that works well for the link of 1 table that i choose to link the problem is that i want to link all tables from database and not doing it 1 by 1.
Is there a way to link all tables from database ???
The code i'm using is :
Dim strConnect As String
Dim strDatabase As String
Dim strTableName As String
strDatabase = DataBase_Now.Value
strTableName = "Tbl_A_Yles"
strConnect = "ODBC;Driver={SQL Server};Server=" & Server_Ip & ";DATABASE=" & strDatabase & ";UID=" & Server_User & ";PWD=" & Server_Pass & ";"
'Checks to see if table exists. If it does, delete it.
If TableExists(strTableName) Then DoCmd.DeleteObject acTable, strTableName
'And then use the trusty old TransferDatabase method to re-link the table declared in strTableName from the SQL Server
DoCmd.TransferDatabase acLink, "ODBC Database", strConnect, acTable, strTableName, "dbo_Tbl_A_Yles"
Thanks in advance.
I want a linked table in my current database. The server where the other access database is already has a ODBC connection created. How to I create a linked table to that other Database through the odbc? I know this is very unspecific, but I do not know what to do on either end. Thanks

I am working on an MS Access database that will connect to an MS SQL db back-end through ADO code only (no constant connection), so I am using connection strings when it is needed to pull back data, other wise it is not connect to the back-end database.
I am trying to get the code correct, and I believe I am close but missing one piece. Here is an example of what I have so far:
--------------------------------------------------------
Dim cat As New ADODB.Connection
Dim cmd As ADODB.Command
Dim rs As ADODB.Recordset
cat.ConnectionString = "PROVIDER=SQLOLEDB;SERVER=KCNTLBASE;DATABASE=Test;U ID=testuser;PWD=testpassword"
cat.Open
Set cmd = New ADODB.Command
cmd.ActiveConnection = cat
cmd.CommandType = adCmdText
cmd.CommandText = "Select MttrNm from dbo.Page0"
cmd.Execute
Set rs = New ADODB.Recordset
rs.Open cmd 'cmd.Execute
MsgBox rs.RecordCount, vbOKOnly, "Test"
'Debug.Print rs.GetString
cat.Close
-------------------------------------
I believe my error is at this line:
cmd.ActiveConnection = cat
I want the cmd to use the connection string. But all the help I find is just the code "CurrentProject.Connection" which only connects me to the MS Access database itself.
Does anyone know what I need to place here so that the cmd is using the correct connection string to the SQL back-end?
Thank you for your time.

Error!
'C:domains bnaglobal.comuser\_xxyyzzARZTU893 4.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.
How can I fix this connString so my DB can work.
Here are the various options:

I have been trying to get a connection string to work with an OLEDB provider. I beleive the format of the string I was given is not correct. Here is a copy of the code. The string starts with quation marks but does not end with same. If I add the quotation marks I get an error. I have checked the string and it does not show the password included.
Dim rstSource As Object
Dim rstTarget As Recordset
Dim Datapath As String
Dim DataSelector As String
Dim Connection As Object
ClearCustomers (True)
Set rstTarget = CurrentDb.OpenRecordset("Profile", dbOpenDynaset)

I have been happily linking to a MySQL database via ODBC for a while but all of a sudden, Access 2003 is crashing whenever I try to see the actual MySQL database. No message given. It just gives the Microsoft Error window and closes down the MDB. ODBC tests succesfull. Any ideas?
View 14 Replies View RelatedI am an A2K novice and I need some help with connecting to an AS/400.
I have my ODBC data source created and it works well. I'm comfortable with the SQL syntax I'll need in A2K to fetch my AS/400 data. I have no idea what is necessary in the way of VB code in A2K to do the connection. Can somebody point me in the right direction where I can find some code samples? I searched this board prior to submitting this thread but came up empty. Time is ticking on this project.
All help is greatly appreciated.
