R – Zlib in Delphi 2009

compressiondelphidelphi-2009soapzlib

I am upgrading a app to Delphi 2009. The app uses Soap and we compress the soap request and response streams using Zlib. This works fine in Delphi 2006 but not in Delphi 2009.

So I went back to Delphi 2006 and changed to use FastZlib. It all worked fine in Delphi2006 but does not work in Delphi 2009 and I get Decompress errors.

Has anyone else had this problem?

How do I go about fixing this?

I just looked through the built-in Zlib.pas and it appears to have been updated for D2009 properly. What's giving you problems?

Step 1

Clean out the registry of all things Delphi 2009.

You're looking for HKLM\Software\Codegear\BDS\6.0 and everything under it. Purge the HKCU equivalent while you're at it.

Search under HKEY.CLASSES.ROOT for anything that contains "CodeGear\RAD Studio\6.0" - assuming you installed into the default folder. Purge all those items from the CLSID level.

Step 2

Clean up Windows Installer using the Microsoft Windows Installer Cleanup utility.

Step 3

I suggest a reboot at this stage.

Step 4

Try to install again.

Good Luck!

A workaround is to put this in your code in stead:

{$R res\test.res}

That works on my system with Delphi 2009, both with the IDE and the command-line compiler.

Note that I agree that they broke existing functionality, did you add a report to Quality Portal? If not, please do: ttps://quality.embarcadero.com (this used to be the search engine indexed http://qc.embarcadero.com but that has been shut down; https://quality.embarcadero.com requires a free account to search).
