please does exist some native driver for Informix databases for Delphi XE2 Professional ?
What are you using?
I know that does exist IDAC, now opensource, but these sources are for pre-Unicode Delphi versions and is not easy to change it (at least for me).
Thank you very much.
I also used IDAC before, but with upgrading to XE2 I changed to AnyDAC.

Anybody know if delphi xe7 compatible with windows 10?
Embarcadero says that XE8 is compatible. But tells nothing about XE7.
Yes, you can install XE7 on Windows 10, and the executables that it produces are compatible with Windows 10.
Embarcadero have been producing a lot of marketing recently that implies that you need XE8 to do Windows 10 development. Truth be told, you can use any version of Delphi beyond Delphi 1. Of course the newer versions make life easier, and clearly you need XE2 or later to target 64 bit executables.
So far as I can see, the only Windows 10 specific feature that is offered with XE8 is a Windows 10 style. That was what I took from a conversation with Marco Cantú on the subject. I guess that would be useful for FMX targets. If you are targeting classic VCL apps, and use the standard system theme, then this is of no interest. There's no point at all in faking the system style when you can let the system give you the true style. My old Delphi 6 applications, built with Mike Lischke's theme manager code, look and feel on Windows 10 identical to an application built with XE8.
Although Embarcadero says that XE8 is compatible with Windows 10, I'm unable to install or load our existing bpl projects using XE8 with Windows 10.
I moved to XE8 because our projects wouldn't build with Windows 10 using XE4.
You can install and run Delphi XE7 on a Windows 10 machine. And of course you can compile your projects on Windows 10.
But there were no enhancements made in the VCL or FireMonkey towards the new operating system. There is no official support for Windows 10. Your applications may not look and feel 100% like other applications do on Windows 10. But they can still be run as long as long as they don't use any old API that is no longer supported on Windows 10.
You can install and run Delphi XE7 on a Windows 10 machine.
I just bought Delphi XE2 starter and want to upgrade my projects. One of them is failing because Delphi doesn't know what TAdoConnection is.
I stupidly didn't keep a copy of the package when I D/Led it a few years ago now can't remember where I cgot it from
How to install TAdoCOnnection et al into Delphi XE2? Thanks
Update: alas, I have the Starter edition (who can afford anything else?)
Later update, just in case anyone else wants to do some database stuff with a starter edition.
I paid for AnyDac and was very happy, but then it was bought by Embarcadero, so you can't purchase it separately any more. I have a bug with Sqlite, so am looking for alternates.
Start here http://www.freebyte.com/programming/delphi/#freedelphidatabasecompone
ZeosLib looks very promising http://zeoslib.sourceforge.net/portal.php
It comes with Delphi, as long as you don't just have the "starter" edition, so you should already have it installed. Look in the ADODB unit. There is no other package to download.
It should be there, under ADODB:

http://docwiki.embarcadero.com/VCL/en/ADODB.TADOConnection
http://docwiki.embarcadero.com/CodeSamples/en/ADOQuery_%28Delphi%29
ADDENDUM:
Here's the XE2 feature matrix:

ADO is available on all versions ... EXCEPT the "starter version".
Since you have the Starter version, there is no direct option for TADOConnection. You either upgrade your version of Delphi, or use something other than TADOConnection.
I just bought and installed Delphi XE and was hoping to compile my old D7 project there.
However, I hava a source file that "uses QForms" and that generates a "file not found: qforms.dcu" and I can find no relevant reference to what to do about that file googling around...
Any idea how to solve it?

QForms is from CLX, the Qt based cross-platform library that was introduced with Delphi 6/Kylix. So far as I know, CLX is no longer shipped with Delphi.
You need to do one of the following:
Stick with Delphi 7.
Port the code to VCL. This will tie you to the Windows platform.
Get Delphi XE2 and use FireMonkey since clearly at some point in time this code was intended to be cross-platform.
We are migrating from Delphi 6 to Delphi 2010,earlier we were using BDE engine to connect to Sybase Database from Delphi 6. We found out that Delphi 2010 does not support BDE.
We are trying with dbexpress but we are not able to catch the exception(raise error) thrown by Sybase.
Could you please let me know if there is any other driver except dbexpress to connect to Sybase Database from Delphi 2010.
Thanks.

You can use AnyDAC to connect to:
Sybase SQL Anywhere (AnyDAC native driver)
Sybase Adaptive Server (AnyDAC ODBC bridge).
I suspect your real problem is that you have the Professional version of Delphi rather than Enterprise. As far as I know, BDE can still be used with Delphi 2010.
With Delphi 6 the Professional version allowed connections to remote databases. Somewhere between Delphi 6 and Delphi 2010 that policy was changed.
Anyway, you really need to give up on BDE and move forward.
Edit: (jeroen)
The BDE for relational access (aka the BDE SQL Links technology) has been deprecated since 2002, about 2 years after the introduction of dbExpress in Kylix and Delphi 6.
You could try a workaround:
Install Delphi 6
Update BDE to the latest available version (there should be some updates on Embarcadero site, I hope)
Install Delphi 2010
IIRC the available SQL Links should not be removed (otherwise it would break the older version), and they should still work in Delphi 2010. But that's really a stopgap try.
Devart's UniDac can connect to Sybase without using dbExpress, but I never used it.
Sybase drivers for dbExpress is included in Enterprise version of Delphi. If that is not an option you can use dbGO (ADO) that is included in Professional.
You can try ZEOSLIB which contains SyBase connectivity, along with many other SQL dbs.
As far as I can see, it requires you to remove your Query/Table objects and replace them with its own Table and Query replacement objects, but then, so would moving from BDE to ADO/dbGo or dBExpress.
And you really should get the BDE out of your application. It's dead as a doornail.
I need to migrate to RAD Studio and have this installed on a new workstation. At the moment I still need to develop with Delphi 6 until we get all the necessary control updates and sort out the version control.
So my question is can I just install Delphi 6 on the same machine with no adverse impact for either product?
Thanks in advance.
There are no problem to install D6 and RAD 2009 at the same machine.
I think that it's better install first the previos version (first D6 and after D2009), but it's not absolutly necesary.
Regards and excuse for my bad english.
Installing them on the same system is no problem at all.
For migration, our clients have good experience with migrating to Delphi 2007 first, then do the Unicode migration to Delphi 2009 or Delphi 2010 second.
Doing both migration at the same time can work, but usually result in a migration that is too complex to do in one step.

I have delphi 3 to 2009 installed in my machine and I dont have any problem with any of the the Delphi IDEs. Only the BDS 2006's C++ IDE does not work anymore. There is a problem when C++ builder 2006 and 2007 installed in the same machine.
