I use Microsoft ODBC For Oracle, and process a distributed transaction with ransactionScope, but, the code throws a error: ERROR [HYC00][ORACLE][ODBC]option not implement, my code is in vb.net.ere is my code:
sub Main()
dim strConn1 as string = "Driver={Microsoft ODBC for Oracle};Server=server1;UID=user1;PWD=pwd1;"

I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
I have an error ERROR [22018] [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. and I've been trying to solve this but unfortunately I couldn't get the hack of this error. I'm a newbie in dotNet.

I'm trying to develop a simple app with vb.net in VS 2010 that could monitor the ODBC connections via DSN made on the macnhine running this app.My scenario is an application (non Vb) running on a workstation that connects to an MS Access database on a network share.
The application (non Vb) connects using a link (ODBC connection via Oracle 10G) to the tables on the Oracle side.My VB.net Application should monitor the machine running the main application for ODBC connections drops and alert me via email for example.My question is where in the framework can I find something to instantiate or reference in order to check ODBC connections states constantly as well as network disconnection issues as well so I can log and /or alert when possible for network problems and ODBC connection problems for all the applications that might run on the host (machine running my vb app).
I'm connecting succesfully to an Oracle 10g DB with an the Microsoft ODBC for Oracle driver.Regular queries without parameters work fine, but parameterized queries act as if the parameters aren't getting passed in.ex.
--this works fine
Select * from tbl1 where column1 = 'test'
--this doesn't
select * from tbl1 where column1 = ?
--odbc string parameter 'test'
Here's what my connection string looks like:
"Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _
"(ADDRESS=(PROTOCOL=TCP)" & _

I do need to connect oracle database via odbc in my vs 2005 project. I have no idea how to connect, kindly give me connection string codes and prerequisites.
View 7 RepliesI'm converting some RDO code to ODBC Provider code in .NET.The problem is parameter names were not specified in the orignal code, but param values were retrieved by parameter name after the command was executed.Is there anyway to have parameter names populated by the provider once the command is executed so calling code can access params by name.Let me show you an example of the declaration of param and accessing of it.
[Code]...
You can now see how this "used to work in RDO/VB". For some reason it would accept this and know what the param names were after execution. I imagine it had to do another round trip to the db to get this info.
Is there anyway to mimic this behaviour in .NET for ODBC Provider (using Oracle)? Or am I stuck manually specifying the param names in the code (I understand this is the better option, but wondering what the alternative is to match the original code as closely as possible).
I am trying to coonect to Oracle 10g database through ASP using ODBC connection. The connection string used is con.Open "DRIVER={Microsoft ODBC for Oracle};SERVER=xxxx;UID=xxxxx;PWD=xxxxx".
This works when I tried creating a macro and also using a vbs script. When run through classic ASP it gives error on the connection.open line.

Hundreds of our customers have an application that has used ODBC connections to their databases.I am writing a new application in VB.Net and am trying to use several ODBC connections and on all of them I am getting this error:The 'Microsoft.Jet.ODBC.4.0' provider is not registered on the local machine.
Here are a couple of connection strings I have tried that return that error:
Provider=microsoft.jet.ODBC.4.0;DSN=GeneralBill;UID=;PWD=;
Provider=microsoft.jet.ODBC.4.0;Driver={SQL Server};Server=Bill;Database=General;UID=;PWD=;
This one has me baffled.
I need to use the ODBC connections as we have hundreds of customers who have already configured them using a DSN or direct connections on another product that this program is going to complement.
I have an error "ERROR [22018] [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression". I am using VBdotNet2005 and MS Access as its database, and I can't really get the hang of this error.

I have a small vb.net application that fires a crystal report through crystal viewer.
The report uses an ODBC connection provided by 32-bit software accounts package, which is installed in the ODBC 32-bit This all works fine on 32-bit XP and 32-bit Win7 with no problems, When run on a win7 64-bit machine the application launches ok, but when it comes to running the report, it prompts for a database logon box for the odbc connection.
When the report is run seperate on its own, on the exact same pc through crystal reports desginer it runs fine, Its almost like the application is not picking the 32-bit ODBC set up is it the case that the connection needs to be coded rather than using the report connection,

View 2 RepliesI'm currently working on a legacy project in VB.NET 2.0.The project has a very funny DAL-layer which does not incorporate transactions :-|Anyway, it's my job to make some parts of the program transactional and I don'thave access to the DAL layer code.So I'm trying to put entire sections of code inside single TransactionScope.

Running this against both our production and test Oracle 11g database sporadically (or if there is a pattern, I haven't found it yet) generates the Oracle Error:ORA-02049: timeout: distributed transaction waiting for lock Since this is the only process running against the test database, there shouldn't be any issue with different users competing for a lock.
I came accross TransactionScope as I try to resolve an issue bothering on the use of Transactions on Typed DataSets. But when I tried to implement it, my intellisence does not recognise it. I have to Import System. Transaction. TransactionScope but it is not recognised. How do I use it cos it seems like it holds some clues to my problem?Only performance counts!
View 5 RepliesI have some VB.NET code that creates a TransactionScope instance:
LoggingUtility.LogDebug("UpdateCallTable", "SatComCallDataImporter", "About to associate call data with contracts")
Using ts = New TransactionScope()
LoggingUtility.LogDebug("UpdateCallTable", "SatComCallDataImporter", "Getting all unimported SatCom calls")
My application is throwing an exception on the call to the creation of a new TransactionScope, with "Object reference not set to an instance of an object.". The exception isn't thrown on my development machine or my test machine; only on the customers production machine, and I have no idea why. I've placed debug lines immediately before and after this line so I'm positive it is this line causing the problem.
A have used TransactionScopes throughout the application and this is the only place throwing the exception on the client machine."About to associate call data with contracts" gets written to the log and the next log entry is the "Object reference not set to an instance of an object".
Code works fine if I move it out of a transaction.I've been struggling with this for 4 days now and have got no closer.
I'm encountering a hang when the program tries to access the fruit database. I've already enabled network access MSDTC on both my development computer and the SQL Server server.

Does the database connection have to be set inside a TransactionScope?
Or can I set it in the ctor and then have instance methods create up a TransactionScope?
EDIT: e.g.
Public Sub New()
Dim conn = new SqlConnection(...connection string)
Public Sub SomeClassMethod()
[Code].....
the question is do you need to create the connection to the database after you've created a TransactionScope or can it be done before?
I have trouble using the transactionscope on SQLite, i am using the following code. Changes are still commited to the database while i don't call the ts.Complete() function.
Using ts As New System.Transactions.TransactionScope()
Using sharedConnectionScope As New SubSonic.SharedDbConnectionScope()

I have a simple Windows Service that reads from an Excel spreadsheet and imports the records into a SQL Server 2000 database table. Before it loads it checks if the file has been successfully imported before (using filename) and whether any of the records in the file have been imported before (using primary key). If these checks are ok I load the records into a datatable and then update the datatable to the database.
However, I need to do this in a transaction as I want to ignore the whole file if there is an error. The file goes to a discarded folder and the user gets an email with why the import failed. (This is likely to be because the store the record is for is not yet added to the database and the referential intergrity of the db fails). If there is no transaction the records before the failure record are imported. When the file is imported again (the store has been added to store table) the file is then rejected because duplicate records are already in the db.
Heres my code:
