| Migration Windows Application From Delphi 7 to Delphi 2007 for Win32 |

Hi,
Recently I download Codegear RAD Studio trial version to try upgarade our
Delphi 7 desktop application. I copied my source code to a new folder, when
building I got "[DCC Error] DataManagement.pas(319): E2003 Undeclared
identifier: 'VarToStr'.
Checking with Delphi 7 I know the VarToStr function is defined in
Variants.pas/dcu under "Program files\borland\delphi7\source\rtl\sys
folder.
But there is no such a folder for Delphi 2007, though there is a
Variants.dcu file under D:\Program Files\CodeGear\RAD Studio\5.0\lib
instead. I don't understand why the Variants.dcu not works.
I also copied the Rtl folder to D:\Program Files\CodeGear\RAD
Studio\5.0\source\Rtl, but go more errors.
Could anybody shed me the light on this problem? Thanks.
Chris

Have you added the Variants unit to the uses clause of DataManagement.pas ?

It may work - is it actually part of the uses clause?

Which RTL folder? Of Delphi 7? That's not a good idea of course (you
should not mix RTL source from different versions of Delphi)...

Thank a lot, Bob!
it turns out the conditional directive in the unit:
uses
Classes, Sysutils,
{$IFDEF VER140} Variants, {$ENDIF VER140}
{$IFDEF VER150} Variants, {$ENDIF VER150}
FrameWork, ADODB_TLB, ComObj, IDAllocation, Dialogs;
It seems in Delphi 2007 it doesn't define VERSION140 or 150 anymore.
Now I can build the project in the Delphi 2007. Thanks again.

That's correct - VER140 was for Delphi 6 and VER150 for Delphi 7.
Delphi 2007 is using VER180 ;-)
