i am trying to save information in to my access database , i created new instance of an ADODB.Connection object and ADODB.Recordset object but visual studio 2005 is given me an error message that ADODB.connection and ADODB.Recordset are defined?
this is my code
Public Class Form1 Dim con As New ADODB.Connection Dim rs As New ADODB.Recordset Dim str As String

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.

I have defined my ADODB recordset and when I code stringVariable = recordset!tablefieldname the build throws the exception above. My guess is that I am missing a .NET reference but I am stumped. SQLServer 2008 and Visual Studio 2008 - Visual Basic
I 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
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.
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 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'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 have a C# example that is populating a multiselect combobox. This was from an example found online. It works fine with the static values coming from the observable collection. I want to change this to be database driven from a SQL Server backend, but was having issues. I did get it to populate the combobox, but the selection is acting kind of screwy. Some type of simple query from a Northwind table would suffice such as: "Select CategoryName from Categories".
It was written in vb6 and im trying to rewrite it in vb.net. I've completely stripped the program down from all the unneeded fancy addons and now just have the needed code to run it. The program retreives the records, but does not populate these records onto a datagrid.
Heres my Form code (Form1) Imports ADS_SQL_TEST_VBNET Public Class Form1 Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
I think the problem lies within the LoadDataBound() Sub routine, but I can't say for sure since I was unable to fix this myself.
I consider myself a very patient guy with a whole lot of determination to get things working within say, a program i'm working on. However, I feel that I am only wasting precious time that I could be using to actually gain knowledge in something rather than hitting my head against a wall accomplishing nothing.

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") rsInUse.Open(OpenCommandSQL, dbInUse, ADODB.CursorTypeEnum.adOpenKeyset, ADODB.LockTypeEnum.adLockOptimistic)
Anyway, I wrote a view with a union query in SQL Server that grabs data from a linked SQL server.
Anytime I try to add this object as a dataset in VB.NET it completely bombs out on me with this ugly error message...
ERROR  [Microsoft] [ODBC SQL Server Driver] [SQL Server] The operation could not be performed because the OLE DB Provider 'SQLOLEDB' was unable to begin a distributed transaction. ERROR  [Microsoft] [ODBC SQL Server Driver] [SQL Server] [OLE/DB provider returned message : new transaction cannot enlist in the specified transaction coordinator] ERROR  [Microsoft] [ODBC SQL Server Driver] [SQL Server] OLE DB Error Trace [OLE/DB Provider 'SQLOLEDB' lTransactionJoin::JoinTransaction returned 0x8004d00a]
I'm completely stumped as to why I can't create a dataset from a view that references a linked SQL server. It's not this specific view either, all views that reference this linked server bomb out.
I recently updated an app that I wrote to allow the clients to run the app in read only mode disconnected from the database by serializing the typed dataset, and when they are offsite/offline instead of connecting to the database the serialized dataset is loaded. This has been working great and then I hit a major snag.
A majority of the graphs and reports are based on sql views that are typed views in the dataset. Of course offlline the tableadapters cannot run the sql views.
Does anyone know a way to run/fill the view with the already loaded dataset? I can add rows clientside so I'm inclined to believe there must be some way to fill the view clientside but I've been at this for a number of hours now and not making any real progress.
i am trying to get data from the clipboard into dataset and view it on a datagridview using the code below. The problem is that every line after the first line starts with a character (like a small rectangle) but when i run a sperate loop to view each character i do not find any unexpected asc code.

There is a "how do I video" on how to properly control updates, inserts and deletes in multi-user applications on forms that edit master-detail related data. [URL] Massi worked through the process using Order (OrderID is PK) as the master table and Order Detail (OrderDetaiID is PK) as a related table in dataGridView. The dataGridView automatically generate orderDetailID whenever the mouse enters in a new row. I am doing a similar form, but placing order form and orderDetail form in two separate tabs in a tabcontrol, and also using Details view for both tables. When I click "new" button in BindingNavigator, the orderID is automatically generated. If I use dataGridView for my orderDetail tab, then the orderDetailID is automatically generated when the mouse enters. This allow me to insert/update tables correctly. However I need the Details View for my orderDetail form too. How do I get a orderDetailID automatically generated when user insert a new order and have the mouse click on OrderDtail tab?
I'm converting a VB6 + ADODB app to VB.NET 2010 and targeting both x86 and x64 I understand that ADO is available in both 32 and 64 bits and that .NET supports it.The VB6 code uses ADODB and ADOX to work with OleDb and Odbc data sources. It also uses the Jet and Replication Objects 2.6 library to compact and copy Access database files (if the uderlying database it's using is Access)I'm wondering if I should consider using OleDbConnection/OdbcConnection in the .NET version of the software or stick with ADO.I've looked at OleDbConnection, OdbcConnection and SqlConnection and can see that porting the old code over would be time consuming and risky.
I created a sample ASP .NET app. I set the location to File System. When I tried to debug it I get an error message: "Internet Explorer cannot display this webpage". I was meant to understand that I can test this app. without Internet Connection. Why is it telling that?Only performance counts!
in my project i have inserted a dataset and created a table using design view with columns "id", "name" and "add" and used this table in my crystal report.
Now what i want.I want to send details from text box to dataset so that when my report is generated it will show those data. i am familiar with saving data in normal database table Access or sqlserver. but i dont now how to save in dataset.me the code to save data in dataset from textbox as well as if i want to save from datagridview.
