Converting ADO to ADO.NET
Hi, I am trying to convert this code from ADO to ADO.NET
I am very new to ADO.NET and am a bit confused on how I would convert this.
Basically what I am trying to do is capture the name of the fields of a table to populate a dropdownlistbox. The table name will change every time the program is run. This is not a problem and I can code for that.
Here is what I have in ADO (I have tried the wizard but it did not change the code)
Dim tblFields As Object
Dim myRst As New ADODB.Recordset
Dim myField As ADODB.Field
Dim myCnn As New ADODB.C...Does .NET map calls for ADO to ADO.NET?
Hello,We are trying to troubleshoot some DB problems from COM objects that call ADO. I heard that when ADO is loaded inside of a COM object by a .NET app, that .NET intercepts the call and re-maps those calls over to ADO.NET. This seems untrue to me, given the nature of ADO.NET being a totally separate technology.Does anyone know for sure whether this does or does not occur?The problem we are seeing is actually almost identical in symptoms to this:http://support.microsoft.com/default.aspx/kb/230101"FIX: Data Queries Sporadically Return Empty Recordsets" Literally, this is what...ADO.NET equivalent to ADO recordset
I'm new to ASP.NET 2.0 and ADO.Net but have some experience with oldschool ASP and ADO :)My question is ADO.NET has an equivalent to ADO recordset?In normal ADO I use to read and compare database cells 1 set User= Server.CreateObject("ADODB.Recordset")
2 User_sql = "SELECT * FROM tblUsers WHERE UserName='" & Request.Form("UserName") & "'"
3 User.open User_sql, Conn
4 5 if User("Password") = Request.form("Password") then
6 Response.write(User("Password"))7 end if ...ADO in VB6 vs ADO.NET in VB.NET
I am writing a database interface and I would like to know whether a
VB6 interface using ADO or a VB.NET interface using ADO.NET would be
faster in terms of just performing database operations. Is there an
explanation for this, and what is the magnitude of the difference?
Thanks in advance!...ADO not ADO.NET
I have to connect to a db using adodb (which i select from the references). I have to retrieve the car models from the database and bind them to a listbox. I am not sure how to proceed and I can't find any articles on ADO with .net and data binding.
Here is the code that i tried but it only retrieves the car model for the specified id. If I delete the id it doesn't work. Also it writes the car model in the listbox vertically such as:
Public Class listboxADO

can somebody tell me
how to cast a Recordset from ADO to a ADO.NET Data Struct
the ado recordset is in a dll that is called from an app
that is being build in C#.NET
Thanks in advance

You can't. You can only cast objects that inherit from the same base class (oversimplification, but that's the gist of it).
It sounds like you want to convert it from a recordset to something else in .NET, right? What do you want it as? XML data? A data set? Something else?
Give us more information and we'll try to help.

Matisse Software Inc. provides its native ADO.NET Data provider for Matisse 6.0, the Database for .NET. Matisse Software has pushed the envelope of Microsoft ADO.NET architecture and extended it into a powerful Object Access Services component for .NET.
Matisse’s extension of ADO.NET demonstrates that ADO.NET can evolve beyond the Microsoft architecture to benefit .NET developers. Unlike the standard ADO.NET data provider, which returns data in a table format to integrate seamlessly with relational products, Matisse has extended the ADO.NET architecture to return data in an object format....using an ADO.NET dataset as a datasource for RS
Is it possible to use an ADO.NET dataset (as opposed to a Reporting Services dataset) as a datasource in Reporting Services? Thanks.
unless I misunderstood your question, I dont think they are different. what xactly is your question.***********************Dinakar NethiLife is short. Enjoy it.***********************
Yes, they are different. The datasource of a Reporting Services report is called (unfortunately) a "dataset," which is different than a dataset in ADO.NET. My question is as follows: let's say, for example, that I create an ADO.NET dataset in V...ado.net or/and datawindow.net
Can datawindow.net work with Sybase's ado.net or are they not compatible
with each other.
We have two separate groups of developers, one group develops web apps using
ASE as the back end for the data, so they use a combination of Visual Studio
..NET and Sybase's ado.net to do their work. We have another group that
develops client/server apps using Powerbuilder, but since 80% of their work
is in writting reports using Powerbuilder, I was wondering if they could use
a combination of datawindow.net and ado.net to put make these reports
