Convert Delphi 5 ADO App to Delphi 2007 ADO.NET
I have an appliction tha that is writen in Delphi 5 with ADOConnetion, ADOTable, and ADOQuery components. I need to upgrade to Delphi 2007 and use ADO.NET. I have the program building in with Delphi 2007. Is there anything I need to do to convert the ADO to ADO.NET? > I need to upgrade to Delphi 2007 and use ADO.NET.

ADO not ADO.NET
Hi, 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: B M W CODE: Imports System.Data Imports ADODB Imports System.Data.OleDb Public Class listboxADO Inherits System.Web.UI...

ADO to ADO.NET
I'm an ASP programmer (VBScript) moving on to ASP.NET. So far I'm using:Microsoft Visual Studio 2003ASP.NET with C#I'm working on converting my code over to C#, from VBScript. Now, here is my code in VBScript (modified to better understand it, this is a edited ugly version):Function ExecuteSQL(sqlStatement)    ConnDriver = "Provider=SQLOLEDB; Data Source = " & dbIP & "; Initial Catalog = " & dbName & "; User Id = " & dbUser & "; Password=" & dbPassword     Set connTemp = Server.CreateObject("ADODB.Connection")    connTemp.Open ConnDriver        Set rsTemp = connTemp.Execute(sqlStatement)            Set ExecuteSQL = rsTemp        Set rsTemp = Nothing    Set connTemp = NothingEnd FunctionNow as you can see, this makes it easy for me to execute database connections, which can be done like this:Set rsTemp = ExecuteSQL("SELECT * FROM tablename ORDER BY id DESC")  Do Until rsTemp.EOF = True      Response.Write rsTemp("name")      rsTemp.MoveNext  LoopSet rsTemp = NothingThis code will loop through the database, displaying all the results in descending order. It will write the information from the column named 'name'. That's all well and good, but what I'm experiencing is using ADO.NET isn't as easy or simple as this.So far, I'...

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.Connection Dim cmdText As String Dim cnnString As String cnnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<database>;Persist Security Info=False" With myCnn .ConnectionString = cnnString .Open() End With cmdText = "SELECT * FROM <table>" myRst.Open(cmdText, myCnn) tblFields = myRst.Fields Dim TotalCount As Integer TotalCount = tblFields.Count For Each myField In tblFields Debug.Print myField.Name Next myField myRst.Close() This code works in VB6, but I really need it for an ASP.NET application. I want to get away from ADO and into ADO.NET Any help would be greatly appreciated! Thanks There are way to many way to list how to do this. You co...

ADO vs ADO.NET (Part #1)
Hey,For some reason I am having trouble figuring out how to do things using ADO.NET.

I have a few books but they are not doing a very good job of teaching me and each book uses its own method.... I loved how simple ADO was.. sucks they had to go and change every detail of it for .NET (although I do like the fact there is not a persistant database connection)Classic ASP ADO CodeTake into consideration that strCon already has the connection string definedDim adoConDim ado...

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...
