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:

Is it work?
Anybody test this configuration? As i can remember ASA7 don't work with
Delphi via ADO.
I haven't tested ASA8 with Delphi, but I'm using ASA7 with Delphi 5
and ADOExpress. There are some glitches, but ASA support has been
very helpful with addressing the problems.

...ADO DBXCommon driver binding errors [Edit]
Hi, I am running into issues with ADO.Net and Interbase.
I am not sure where to post, so I assume I start here...
My C# application is crashing with the exception copied at the end of this message (I have enabled binding logging)
Looking at the full fusion log, it looks like:
adoDBXClient is loading DBXCommonDriver, successfully
then DBXCommonDriver tried to load DBXCommonDriver again, but somehow with a different public key. The assembly can not be found, and the app fails.
This application runs fine on my machine and fails on a similar machine. Both machines have Delphi (20...ADO Connection not working if Delphi and Oracle not on same computer
I had Delphi working fine with Oracle using ADO when Oracle 11g is on the same pc as Delphi. I tried to use Delphi from another pc and I do not know what to enter for "Servername" on the Build connection string screen. Originally I had tough I needed to enter the computer name, aka Hostname. I also tried entering a name of the oracle instance or Oracle service, and also tried using this info in for format of hostname.service and \\hostname-service.
Can someone help -is it just the computer name, is it the ip address, does it need the Oracle instance name?
Hel...ADO with MSDASQL and TClientDataSet : Error with TTimeField [Edit]
When using MSDASQL provider with ADO (to use ODBC driver) + TClientDataSet , the value of TTimeField fields is lost on post, with or without error, depending of the ODBC driver.
Tests have been made with 3 databases with ODBC drivers :
In each case , when calling the ApplyUpdates() method on the CDS, the TTimeFields are sent as date type ( a date around 1899-12-30).
Queries on the network have been captured.
For MySQL :
update sejours set sej_sms_heure = _binary'1899-12-30' where sej_id = 1215
For Postgres :

I have an app with a form with two dbgrids setup as master/detail. I placed two TGroupboxes with two radiobuttons each. One of the sets of radiobuttons sorts the Projects(master) dbgrid and the other sorts the Comments(detail) dbgrid. Both sorts are on a date field in the underlaying ADO tables. When I run the app, sorting just one of the dbgrids works fine until I try to click on the other dbgrid or the associated radiobuttons at which time I get the "Type Mismatch" error popping up.
The ADO components are on a datamodule and are as follows:

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

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
