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 tried to connect to ASA7 via the new OLE DB - Provider and ADOExpress from
Delphi 5.01. No chance. Only the error message 'Invalid Enum Value'. About
the new provider I haven't heard anything good until now...
I've experienced the same problem with the ASA 7 OLEDB Provider.
I'm not sure if this is a bug in the AsaProvider or Delp...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:

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...ODBC with ADO
I'm trying to connect to a Sybase SQL Anywhere 5.0 database via ODBC Using
Visual Basic and ADO. I am having very flaky results. The SQL statments
work great with the ISQL tool, but when when I execute them from my VB app,
the VB generates a Dr. Watson error log file and aborts. I do not even get
a error message or code.
It's not 100% of the time, either. I have a few SQL statements that work
all the time and some that don't ever and some that do once and a while.
I am pretty sure it's how I'm opening up the Sybase database via ADO in my
VB app. MS A...ADO.NET VS ADO
I am having ADO.NET course these days. I asked the instructor that developing online system like airline reservation system needs to a connected environment to lock/Unlock the table when u read/write to it Can that be acomplished using ado.net.
His answer was no
ADO.NET is only for disconnected environment and it will not work with online system and i still should use the old ADO. ADO.NET is not a replacment for ADO and both will continue in paralell.
IS his answer true that ADO.NET will not replace ADO and both will continue

I have an SQL database
In Delphi I drop an ADOConnection1 and have no problem connecting to the table using the Browse button
I can compile and run it
When the form opens i want to be able to do
procedure TForm1.FormCreate(Sender: TObject);
Index := ADODataset1.RecordCount; //error
Edit1.Text := IntToStr(Index);
To show the number of records in the table.
I know I am doing something wrong with the lines that have //error
but can not locate good docs or examples for those command

Looking for a little expert advise.
I'm writing an application that requires a database that will be located on
the client machine and only be accessed by the single person on the client
machine.... so not very demanding at all from a connection standpoint.
I started the app with MS Access connection via ADO and I'm wondering if I
should switch to Firebird embedded instead.
Are there any Pros/Cons to each... such as memory usage, speed, or any other
overhead such as needed dlls to distribute with the app?
To me Access might be the easiest, but I'm wo...ADO

Does anyone have any examples of using Microsoft's ADO and powerbuilder.
I am looking into ways of getting metadata of any connections I make in my
Powerbuilder Application. Currently I am using the ODBC API's to achieve
this. I have looked and tested some ADO calls in VB and find that it is
much faster than ODBC in getting metadata.
Thanks In Advance
