How to update Indy component library in Delphi 7

Hi,

During the development of an application, unfortunately I faced a problem that forced me to update the Indy library version of my Delphi 7. I really don't liked the idea, but it was the only solution to continue the development...

I think that if you are here, is because you are facing the same problem, so bellow I listed the instructions to update the Indy component library on Delphi 7 and be happy again! =)

Don't worry if you use another version o Delphi, instructions are the same for all versions, just change the Delphi 7 references by your own version.

First of all, you need to download the latest package from the Indy component repository:
http://indy.fulgan.com/ZIP/
(The latest file version while I writing this post is Indy10_5060.zip)

Now you are ready to start the process of uninstall old version and install the new one.

Open your Delphi 7 and access Components > Install Packages.

Search for the package named Internet Direct (Indy) for Property and Component Editors. Select it and click on Remove button.

This will remove the Indy components from the development enviroment and they won't more avaiable in the components pallete.

After this, exit and close Delphi application and access its install directory. Inside bin folder, search for dclindy70.bpl file and remove it if exists.

Ok, the uninstall of old packages was completed and we will start the install process of the new version of Indy.

To simplify the nexts steps, unzip the content of previous downloaded file in a folder named Indy10 (you need to create this folder), under <Delphi install dir>\Lib.

On a command line prompt, access <Delphi install dir>\Lib\Indy10\Lib folder and execute the batch file Fulld7.bat. It will remove the binary install files of other Delphi versions.

Run again Delphi and one-by-one, open and compile the files listed bellow, respecting their list order:

         1. IndySystem70.dpk (in Indy10\Lib\System)

         2. IndyCore70.dpk (in Indy10\Lib\Core)
         3. IndyProtocols70.dpk (in Indy10\Lib\Protocols)
         4. dclIndyCore70.dpk (in Indy10\Lib\Core)
         5. dclIndyProtocols70.dpk (in Indy10\Lib\Protocols)

After a successfull compile of the packages, you just need to add a new Library path. To do this, access the Tools > Environment options menu, click on the Library sheet and add to your Library path, the path to <Delphi install dir>\Lib\Indy10\D7.

And the most important step on this post is put this new entry before the $(DELPHI)\Lib as follow the image bellow:

Now, on Components > Install Packages menu, finally add the components packages available in the Indy10\D7, on the follow order:

1. dclIndyCore70.bpl
2. dclIndyProtocols70.bpl

It was a lot of steps to do, but now you are ready to come back and develop your apps using the updated version of Indy components!

I hope it was usefull to you!

With best regards,
Marco.
