To try to fix this problem, the Indy 9.0 install will ask you if you want it to delete some Indy files from your Delphi 6LibDebug directory. We recommend that you click Yes to prevent conflicts between your Indy debug units and the new Indy code. A conflict might occur if you have Borland’s install repair Delphi. Here you can download file Indy 10.6.2. 2shared gives you an excellent opportunity to store your files here and share them with others. Join our community just now to flow with the file Indy 10.6.2 and make our shared file collection even more complete and exciting.

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>LibIndy10Lib 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:

2. IndyCore70.dpk (in Indy10LibCore)
3. IndyProtocols70.dpk (in Indy10LibProtocols)
4. dclIndyCore70.dpk (in Indy10LibCore)
5. dclIndyProtocols70.dpk (in Indy10LibProtocols)

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>LibIndy10D7.
And the most important step on this post is put this new entry before the $(DELPHI)Libas follow the image bellow:

Now, on Components > Install Packages menu, finally add the components packages available in the Indy10D7, on the follow order:

dclIndyCore70.bpl
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.

TIdUDPClient is the base UDP client for sending UDP packets to other destinations. The mostcommonly used method is Send, which uses the Host and Port properties to send a UDP packet. Itaccepts a string as an argument.

There is also a SendBuffer method which performs the same task as Send, except that it accepts aBuffer and Size as arguments.

TIdUDPClient can also be used as a server of sorts to wait and receive incoming UDP packets on anindividual basis.

TIdUDPServer when active creates a listening thread to listen for inbound UDP packets. For each UDP packet received, TIdUDPServer will fire the OnUDPRead event in the main thread, or in the context of the listening thread depending on the value of the ThreadedEvent property.When ThreadedEvent is false, the OnUDPRead event will be fired in the context of the main program thread. When ThreadedEvent is true, the OnUDPRead event is fired in the context of the listener thread.When ThreadedEvent is true or false, its execution will block the receiving of more messages. Because of this the processing of the OnUDPRead event must be quick.

Infos

The TTL property is declared as protected in TIdRawBase, and TIdIcmpClient does not promote it to public. You will have to declare a descendant class to gain access to it, ie:

type

TIdIcmpClientAccess = class(TIdIcmpClient);

procedure TMainForm.PingFirst;

//..

TIdIcmpClientAccess(IdIcmpClient1).TTL := CurrentTTL;

//..

end;

Introduction

Along with ICS and Synapse, Indy is one of the most use open-source set of Internet components. It supports HTTP, SMTP, ICMP, etc.

Note: All Indy exceptions descend from EIdException. By default, Delphi 7 has at least one item in Tools > Debugger Options > Language Exceptions related to Indy, 'Indy EIDSilentException Exceptions', and, possibly 'Indy EIDSocketError Exceptions'.. which do not prevent the IDE to fail when running in the by design exception EIdSocketError 'Socket Error # 10004'. The reason is that the actual exception is 'EIdSocketError', not 'Indy EIDSocketError Exceptions'. Add the former through the Add button, don't forget to add IdException in the users section, and you won't be stopped by the IDE anymore.

Upgrading to Indy 10

Delphi 7 ships with Indy 9. Since the only documentation on the Indy website is now based on release 10, and some examples won't work with older releases, you must remove Indy 9 from the IDE, and install release 10.

There are two possibilities, but both require your uninstalling Indy 9 yourself before installing Indy 10:

upgrade manually following thoses instructions: How do I install Indy into Borland Delphi?, Upgrading to Indy 10, [D7] Upgrade propre des composants Indy vers Indy 10.1.5?, [D7 Ent] How to upgrade Indy properly?, Indy 10 in Delphi 2006
run the upgrader Indy Plus Install, free for personal or educational users, while commercial projects require buying the Indy Plus package

Removing Indy9:

Close the Borland Delphi IDE if it is open.
If you are using the version of Indy included in Delphi 6 or 7, use the MSI installer to remove Indy: In 'Program Files', click on the drop-down list before Indy, and select Do Not Install. If you didn't install Corba, uncheck 'Use Visibrocker/CORBA Support' before proceeding with the uninstall
Remove all Indy files from the Delphi directory, including dclIndy*.bpl, Indy*.bpl, the Id*.pas, and the Id*.dcu's. Take care that you only remove the old Indy files and not something else. Be sure that you also remove any Indy*.bpl from your WindowsSystem32 directory (IndyCore70.bpl, IndyProtocols70.bpl, and IndySystem70.bpl)
When restarting Delphi, it will fail loading the Indy 9 BPL: 'Error/Can't load package c:program filesborlanddelphiBindclindy70.bpl. The specified module could not be found. Do you want to attempt to load the package the next time a project is loaded?' Just tell it not to try reloading this package the next time.

Manually installing Indy10

Place the new version of Indy in a directory of your choice. When unzipping, please keep the source directory for the archive intact because that is used by some build batch files.
In the source directory, there are several batch files. Run the appropriate one for your version of Indy:

FULLD4.BAT - Delphi 4
FULLD5.BAT - Delphi 5
FULLD6.BAT - Delphi 6
FULLD7.BAT - Delphi 7

These batch files create subdirectories in the main Indy directory folder. They are (D4 for Delphi 4, D5 for Delphi 5, D6 for Delphi 6, an
