I have a classic ADO command which execs a sproc and returns a RecordSet. This is being executed from a VB.NET using the PIA.However when I .Execute the command, the result returned is not an ADODB.Recordset but a System.__ComObject.

I have a piece of software I am converting to ADO.NET from ADODB. In ADODB I can update a recordset by simply.
Dim rs as ADODB.Recordset
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
OR IF I WANTED TO ADD
Dim rs as ADODB.Recordset
rs.AddNew()
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
I am confused about to easily accomplish this. I know I can use an insert or update command but it would be much easier to do something like this. NOTE: The query just returns a filled RecordSet, it just executes the command and connection without me having to do it all over the place.
I am new in VB.NET.I Developed Project in VB Recently.In VB6.0 i worked on ADODB Recordset by Connecting Access DB.And i wrote SQL Queries in the Functions and these Functions Called in the Recordsets. I will send u my code wich i developed in VB6 in the below.

I encounter this error as mention in the subject line. I just change from windows XP 32 bits to windows 7 64 bits, and the following code were working fine in windows XP, but in windows 7 I get ambiguous namespace for all the DIM cnn As New ADODB.Connection and DIM rst As New ADODB.Recordset.I Have no idea what is going on.However, the exe that is created from my old XP runs fine on both XP and Windows 7 32 bits but not the Win7 64 bits.

I have a vb program accessing a table in an sql server database. I would like the vb program to wait if it attempts to update a row which is locked in the table. The default behaviour of the recordset seems to be fail immediately with a timeout if the record it wants to update is locked.
The sql server is set to a default lock_timeout of -1 (infinite I believe). Is there a way to have an ADODB recordset wait on a lock (say for 60 seconds) and then fail if it still can't update the record.
I'm in the middle of porting a VB6 product to VB .NET and .NET Framework 3.5, using Visual Studio 2008. Backward compatibility with customer VB6 legacy code is a requirement.Our VB6 product uses the COM ADODB.Recordset objects extensively both internally and in our API. They port directly to VB.NET if I add an adodb interop reference to my VS 2008 project. My question is how long will Microsoft continue to support ADODB.Recordsets in their languages and operating systems? 2018?I'm trying to make a design decision. Since backward compatibility with VB6 is a requirement, I would prefer to leave them in the .NET code. However, if support will be dropped soon in the near future, then I will use ADO.NET datasets instead, and convert between ADODB.Recordsets and datasets until support is dropped.

View 1 RepliesI have a very frustrating problem which is not funny to resolve. This is not supposed to have with Visual Studio 2010, NET framework 4.0. I have to be very efficient on this platform that Visual basic 6.0.
The NET platform should be very interesting on C#, and Visual Basic languages.
In Visual Basic 6.0, the Datagrid (OLEDB 6.0 version) could be populated easily using the ADODB.Recordset object by using the following line
[Code]...
The only way out for me is to use the Add items method using the items from the ADODB.Recordset to add them individually into the NET framework 4.0 Datagrid which is cumbersome code because I need to use For Loops statement etc. This is not good programming practice.I feel like I am going backwards when I am supposed to be moving forward. I use Visual studio 2010 for C# and Visual basic and this should be more fun than Visual basic 6.0 and previous C# 2008 etc. I cannot rely entirely on managed NET framework objects and classes only. I need to use all the objects available to my disposal to programme and come up with powerful Microsoft applications.
I have the following code:
Dim PageNum AS Integer = 1
Dim ThePageSize As Integer = 30
Dim RowCT As Integer = 0

When I try to run it I get:
"System.Runtime.InteropServices.COMException: Current Recordset does not support bookmarks. This may be a limitation of the provider or of the selected cursortype."
The error page points to "Objrs.AbsolutePage = PageNum"
what I can do to get around it? It would kind of really stink to show 500 records on one page.
I'm using an OLEDB connection to a Sybase database, with ADODB.dll file version 7.10.6070.0 (which comes from the Sybase 12.5 package). I need to be able to open a connection, use a command object to fill a recordset from a stored procedure, then close the connection and pass back a disconnected recordset. My attempts so far fail as every time I close the connection, my recordset also closes (which means it is not disconnected).
Is there a property I must set somewhere to indicate that the recordset should be disconnected? I cannot set Recordset.ActiveConnection = False because I get an exception ("Cannot change the ActiveConnection property of a Recordset object which has a Command object as its source."). I do set the Command.ActiveConnection = False, but that doesn't stop the recordset from closing as soon as I close the connection object.[code]...
I am trying to have my application be able to read in some ADODB Recordset XML files, but I was told by my boss that I cannot have a reference to ADODB. I do not know how this can be accomplished.
View 2 RepliesWe have a VB6 program that uses an ADODB.Connection to establish a database connection and use its execute function to run SQL statements. The connection we have established is to a SQL Server. It has been working fine. Currently, I am trying to change the connection to a MySQL database. I changed the connection string and the connection is ok.
However, when it comes to running the execute function, it returns a runtime error 3246 - connection object cannot be explicitly closed while in a transaction.
I checked the connection.status before calling execute and found that it is open. When I use MySQL's server connections to check the status, I found that there was a connection before and after execute was called.
I encountered this same error whether I used MySQL ODBC 5.1 Driver or MySQL ODBC 3.51 Driver.
I am getting errors when I try to use this adodb.connection and command in my code. The error I am getting is saying that the connection and command are not defined. I read online that depending on your version of vb that you might use the "OLE" connection instead of ADODB.

I have two functions in a class. One function returns a datatable, the other one returns a dataset. Both functions are identical except of the return type (Datatable or dataset). I would like to have only one function which returns either dataset or datatable depending on what the user of the class wants. How can I do this.
Following code shows my function returning a datatable:

I've found alot of examples for add/edit/delete a single table. In VB6 ADO you could load multiple tables into a recordset using the join command. Then manipulate or modify the data.
I've found how to retreive multiple tables like,
Da = New OleDb.OleDbDataAdapter("Select groups.groupid,groups.userid,lots.groupid,lots.lotid from groups inner join lots on groups.groupid=lots.groupid order by groups.groupid asc", DB) But the only way I have found to update is to use seperate Update commands for each table.
I have something strange occuring. The following code works 100% when run in VB2008 Express.When compiled and run onthe same system, it generates the above message.The codebasically opens a Access DB and loops thru the db There is a progress bar (also tried a simplelabel) to display progress using AbsolutePosition.
dbInUse.Open("Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:SCDBv4DataSCDBData.mdb")

I'm not sure what's wrong with the following setup. I have a View that lists a number of records, and each has a dropdown associated with it to change a value on that record. I had it all working without AJAX, but you had to change a bunch of the dropdowns then click a Submit button. I wanted to change it so that it would save the dropdown choice immediately.
My stripped down View (of type IEnumerable(Of MyTable)):
<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>
[Code]....
What I would like to happen is for the dropdown change to trigger the Update controller, but probably not return anything - just update the database and let the user move on. What's happening though is that a blank page is displayed with the Content value on it (i.e. "123: ABC"). It's the correct id/code combo, so the Update seems to be firing correctly, it's just choosing to wipe out the html.
like an Interop user control (VB.NET) to return and to accept multiple values from a get/set call.
