Most of the the time my connection is created and closed fine.
However, sometimes I get Connection failures (these happen often because I am connecting to the server using a VPN connection). Once I get the connection failure, sometimes I cannot successfully recreate the connection until I kill the application and restart it. Below is my open and release code. I call release anytime the connection fails or a stored procedure fails. If you see anything wrong with it the code below that would prevent the connection from recovering please let me know.
hi have written SSIS script and i am using script component to Row count below my code what i have written. and i am getting error below i have mention...after code see the error using System;

I have an application which runs successfully on a couple of my customer's machines but fails on a third. It seems to fail when opening the database:
Unable to cast COM object of type 'ADODB.CommandClass' to interface type 'ADODB._Command'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B08400BD-F9D1-4D02-B856-71D5DBA123E9}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=false; Initial Catalog=lensdb;Data Source = SQL
Before I got this error I was getting another problem (sorry didn't make a copy of that error's text) that made me think that adodb.dll simply wasn't loaded/registered. I got rid of that error by copying my adodb.dll onto the third machine and running gacutil /i. There is now an entry in winntassemblies for adodb.
Just in case you think it could be an obvious registry problem: when I started getting the current error I thought that maybe the registry needed updating and I merged the following lines into onto the target machine (from my dev machine):
Am having trouble writing to a table on the SQL 7 Server database, using a DTS ActiveX script.
When I try a .ADDNEW function, the following error comes up. "The opperation required by the application is not supported by the provider."
The line preceding the .ADDNEW are as follows. ----- SET Conn=CreateObject("ADODB.Connection") SET RS = CreateObject("ADODB.RecordSet") Conn.ConnectionString = "PROVIDER=SQLOLEDB;DATABASE=DataIn;User ID=sa;Password=" Conn.Open RS.Open sqlSites, Conn ----
I currently have an access database that is being converted to strictly a Front-End and SQL as the back-end. simple code conversion from DAO to ADODB? I would be very grateful for the infinite wisdom that resides within these boards.

my code is using ADODB connection to connect to SQL (Virtual) Server.the way it being done is (c++):ADODB::_ConnectionPtr m_dbConn;ADODB::_RecordsetPtr m_dbRst;m_dbConn.CreateInstance(__uuidof(ADODB::Connection ));m_dbRst.CreateInstance( __uuidof( ADODB::Recordset ));m_dbConn->ConnectionString=( L"DSN=mydsn" );m_dbConn->Open("","sa","",-1);lately after installing SP3 over SQL2000, it was impossible to connect- the error message showed: login failed for user 'null)'. reason: notassociated with a trusted sql server connection.so i changed the connection string to:m_dbConn-> ConnectionString =(L"DSN=mydsn; UID=sa; PWD=;");m_dbConn->Open("","","",-1);and now it works !!what is the reason for that ?what in sql SP3 interrupt for this kind of connection ?what is the difference ?
I am trying to access a table that I know exists and has data. But, when I create a recordset and check for RecordCount, I get a result -1 (no records). When I access the same table (using the same program), it reports (and I can view in a dbgrid) 752580 records exist.
Here's some of the code:
The table is originally copied from another database; I use the following code to be sure the previous connection is closed before proceeding.
If Not adoRS Is Nothing Then If adoRS.State = adStateOpen Then adoRS.Close Set adoRS = Nothing End If If Not DbConn Is Nothing Then If DbConn.State = adStateOpen Then DbConn.Close Set DbConn = Nothing End If
Then a new connection (it works) is opened to access the database with the copied table:
I have developed an application in vb.net 2005 Standard Edition and is running fine in my local machine. The executed version of the same application i tried to run in other machine and getting an error as follows :-
" Unable to install application. The application requires the assembly ADODB Version 7.0.3300.0 be installed in the global assembly cache (GAC) first "
I am using SQL 2005 DB and i connect it using PHP. I have one Store procedure in SQL which requires 1.5 minutes to get result.
I'm always getting error message in web after 30 seconds that Microsoft OLEDB provider for ODBC drivers, timeout expired.
I increased time in php.ini but the error comes from SQL Server. Can you please guide me to increase the time in SQL. so that timeout doesn't expired. This will help me a lot.
Hi I need help regarding ADODB Connection that i have used in connecting database in my web application, do tell me is this connection type is ok? or I need to switch to ADO.NET Connection.
I have posted various questions on the microsoft ng trying to identify the cause of this error.
ADODB.Command error '800a0cb3' Object or provider is not capable of performing requested operation.
I have MDAC 2.8 installed locally on my machine.
Via IIS I created a virtual directory via IIS that points to my ASP files on c:
Via the SQL Server IIS for XML configuration utility I created a virtual directory with a different names that points to the same directory as that created via IIS.
The SQL database is on a different machine and I connect via the OLEDB DSNless connection string.
I used a ADODB.Stream to transform the XML against the XSL but I couldnt get it to work. To simplify things and work towards a solution I inserted the code into my ASP from the MS KB article Q272266 (see below). I amended the ms code to change the connection code and call a stored procedure that exists on the database. The ms code gives the same error as my original code.
I tried changing the CursorLocation to server and client but the results were the same.
I put a SQL trace on the DB to determine if the stored procedure gets ran, it does not.
If I run the following in the URL it works:
If I run http://localhost/p2/?sql=SELECT+*+FROM+tblStatus+FOR+XML+AUTO&root=root&xsl=tblStatusDesc.xsl it works. If I run the xml template it works: http://localhost/p2/xml/test.xml
The two lines above run. My IIS server uses a virtual directory called dev, so when I run the ASP I type http://localhost/DEV/secure/aframes.asp the IIS virtual directory creted by sql server is called p2 but has the same source code directory.
Here is the MS code amended as described above that does not work.
sQuery = "<ROOT xmlns:sql='urn:schemas-microsoft-com:xml-sql'><sql:query>Select StatusDesc from tblStatus for XML Auto</sql:query></ROOT>" '*************************************************
Dim txtResults ' String for results dim CmdStream ' as ADODB.Stream
Set adoConn = CreateObject("ADODB.Connection") Set adoStreamQuery = CreateObject("ADODB.Stream")
adoConn.ConnectionString = sConn adoConn.Open
Set adoCmd = CreateObject("ADODB.Command") set adoCmd.ActiveConnection = adoConn
adoConn.CursorLocation = adUseClient
Set adoCmd.ActiveConnection = adoConn
adoStreamQuery.Open ' Open the command stream so it may be written to adoStreamQuery.WriteText sQuery, adWriteChar ' Set the input command stream's text with the query string adoStreamQuery.Position = 0 ' Reset the position in the stream, otherwise it will be at EOS

Set outStrm = CreateObject("ADODB.Stream") ' Create the output stream outStrm.Open adoCmd.Properties("Output Stream") = response ' Set command's output stream to the output stream just opened adoCmd.Execute , , adExecuteStream ' Execute the command, thus filling up the output stream.
Hi!I already sent this to the ACCESS newsgroup. But since I do not know reallywhich side is really causing the problem, I have decided to send thisinquiryto this newsgroup also, if I may.Below is the environment of the application:a. MS Access 2003 application running on Windows XPb. SQL Server 2000 - backend running MS Server 2003 OSBelow is the code that is giving me an error:Dim com As ADODB.CommandSet com = New ADODB.CommandWith com.ActiveConnection = "DSN=YES2;DATABASE=YES100SQLC;".CommandText = "sp_Recalculate".CommandType = adCmdStoredProc.Parameters.Refresh.Parameters("@ItemNumber") = ItemNum.Execute ' This is where it hangs up...TotalItems = .Parameters("@TotalInStock")TotalCost = .Parameters("@TotalCost")End WithSet com = Nothingand the store procedure is:CREATE PROCEDURE DBO.sp_Recalculate@ItemNumber nvarchar(50),@TotalInStock int = 0,@TotalCost money = 0ASBEGINSET @TotalInStock = (SELECT Sum([Quantity in Stock])FROM [Inventory Products]WHERE [Item Number] = @ItemNumber)SET @TotalCost = (SELECT Sum([Cost] * [Quantity in Stock])FROM [Inventory Products]WHERE [Item Number] = @ItemNumber)ENDWhen the process goes to the ".Execute" line, it hangs up for a long timethen gives me an error message "Everflow". I have been trying to solvethis issue but do not have an idea for now of the cause.Below is my finding:a. When I run the stored procedure in the SQL analyzer, it works just fine.I placed a SELECT statement to view the result of the stored procedure.It gives the correct values.Can anyone have ideas or similar problems?Thanks.

We just encountered an odd failure in ADODB. If it gets an SQL query with a comment embedded in it, and the comment has an apostrophe as one of the characters, ADODB gets confused as it tries to plug in parameters for placeholders later in the query. For example:
SELECT id, name
FROM doc_type /* this won't work! */
WHERE name LIKE ?
If you take out the apostrophe ("this will not work!") or move the comment to follow the placeholder, the query works.
I use VBA to call a MSSQL server 2000 to get data from one of the DB inside, using ADODB.
My problem is, the DB is around 20GB, and if we get data from it for few days, say 7 days, is fine. When I come to trying get more data like 1 month, the excel returns no data after waiting for about 30 sec.
The query is actually calling a stored procedure on the server side to return data.
I have add connectiontimeout=10000 to my connection string but still not working...
I run the same execute statement in query analyzer on the same machine using the Excel and it is fine. Around 2 minute waiting I can see my data. But in Excel, never.
Hi there, I am trying to use the ADO technology within MS Access 2000. Basically I'd like to use parameters in a command object to insert a new record and get its newly inserted ID. But instead of it it returns error:
Run-time error '-2147217900 (80040e14) Must declare the scalar variable "@ii_file"
Isn't this varaible (and all the rest of variables) declared by setting a parameter ".Parameters.Append .CreateParameter("@ii_file", adVarChar, adParamInput, 255, Me.cbo_ii) "? I'd like to avoid using stored procedures in order to create the whole SQL statement from the client side. Thanks!

I've been trying different things to "READ" the recordset from the "Message Queue". I can read it but with some weird characters. I've tried
ActiveXMessageFormatter
BinaryMessageFormatter
XMLMessageFormatter
So, far I have no luck.
MessageQueue msgQ3 = new MessageQueue("SERVERNM\" + msg.Label, false);
Message msg3 = new Message();
msg3.Formatter = new ActiveXMessageFormatter(); msg3 = msgQ3.Receive(new TimeSpan(0, 0, 30));
byte[] b = new byte[msg3.BodyStream.Length]; msg3.BodyStream.Read(b, 0, (int)msg3.BodyStream.Length); System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
returnVal = enc.GetString(b);
RESULTS: I try to convert it to String and then deserialize later but I'm getting some junk. <?xml version="1.0" encoding="utf-8" ?>
Hi! I have a vb.net program that writes data to an SQL Server database using ADODB. The problem is if I put the code that writes data to the database in between BeginTrans() and CommitTrans(), the database is not updated. Here is the flow of my program:
Dim connection as ADODB.Connection 'setup the connection to the SQL Server database here
connection.BeginTrans()
InsertData() ' --> data is written to the database ' this function works properly
connection.CommitTrans()
If I comment out the BeginTrans() and CommitTrans() functions, the data is properly inserted into the database.
Does an SQL Server database requires special settings to support transactions?
We use a number of similar databases and frequently create a newdatabase using a backup restore of another similar database. We try tokeep changes between databases in _Additional tables - like AccountAdditional, Sale_Additional so most tables stay the same. The latestrestored database (I'll call it DBaseA) is behaving differently in VB6code and I need help trying to make it work.I have been using use an ADODB.Command to execute a stored procedureusing adCmdStoredProc and Parameters.Refresh to get an output parametervalue which is an integer. Here is a sample of the VB:Public Function UnlockAccount(Account_ID As String) As BooleanDim LCmd As ADODB.CommandOn Error GoTo ERROR_UnlockAccountUnlockAccount = TrueIf Account_ID <> "" ThenIf DBConnect() ThenSet LCmd = New ADODB.CommandLCmd.ActiveConnection = CN(0)LCmd.CommandTimeout = 0LCmd.CommandType = adCmdStoredProcLCmd.CommandText = "Unlock_Account"LCmd.Parameters.RefreshLCmd.Parameters("@Account_ID").VALUE = Account_IDLCmd.Execute , , adExecuteNoRecordsIf LCmd.Parameters("@Status") <> 0 ThenUnlockAccount = FalseEnd IfElsemsgbox "UnlockAccount: DBConnect Failed", "UnlockAccount"End IfEnd IfExit FunctionERROR_UnlockAccount:UnlockAccount = Falsemsgbox "UnlockAccount: App Error: " & Err & " " & _Err.Description, "UnlockAccount"DBConnect TrueExit FunctionResume'for debuggingEnd Functionand this is one of the sps that fails - can't be more simple!Create PROCEDURE Unlock_Account( @Account_ID UNIQUEIDENTIFIER,@Status INTEGER =null OUTPUT) AS/* Strip functionality */SET @Status = 0goThis code is still working in at least 4 other databases. It fails indatabase DBaseA with the error:Invalid character for cast conversionWe are talking about the exact same table definition and the exact samestored procedure just in different databases.I fumbled around on the Internet and found a mention in a PowerBuilderweb site of additional parameters in the connect string which seems tofix the problem in SOME of the stored procs - but not all.The added parameters are:DelimitIdentifier='No';MsgTerse='Yes';CallEscape='No';FormatArgsAsExp='N'They are not documented in MS but are in Sybase?? No idea why, but someof the stored proc functions work when I add this to the connect string.The complete connect string is:Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=DBaseA;Data Source=PHASE2-S500,1433;Network Library=DBMSSOCN;DelimitIdentifier='No';MsgTerse='Yes';CallEscape='No';FormatArgsAsExp='N'The databases are on different servers - but they are running the sameversion of SQL2000, the same version of Windows. I see no differencesin options set in the different servers or between databases that workand this one. And dbcc checkdb runs clean.The compiled code that fails, fails across the board - not just on my(developer) PC. The same source code works on the same tables in otherdatabases, including the one we copied....The final kicker - if I build a SQL statement string and get therecordset instead, it works like a charm. But I have to fix about 20 VBfunctions and check that I do have a recordset and SET NOCOUNT ON in all20 sps.I feel this is either something so obvious I will kick myself or soserious Microsoft will be digging into it.Any ideas anyone??Sandie*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
