Delphi 2010 , Indy update

[joeifs814]

Hello, I have a Delphi application developed using Delphi 2010. I am having an issue with sending an email using TLS and based on my research I believe I have to update my version of Indy. Currently using Indy 10.5.5. I'm pretty sure I need to update my version of Indy because my code won't compile because it doesn't recognize "sslvTLSv1_2". In my research I was directed to github to download the Indy update. I don't know what link I would use to download the most current version of Indy that works with Delphi 2010. Also, any directions / instructions on installing the new indy components into my Delphi 2010 would be greatly appreciated. Thanks, Joe

Currently using Indy 10.5.5. I'm pretty sure I need to update my version of Indy because my code won't compile because it doesn't recognize "sslvTLSv1_2".

Wow, that is a very old version. sslvTLSv1_2 was introduced in 2012, 14 years ago.

In my research I was directed to github to download the Indy update. I don't know what link I would use to download the most current version of Indy that works with Delphi 2010.

Indy still supports back to like Delphi 5. Just use the latest version (currently 10.6.3.14 as of this writing), and compile the five ...140 packages for Delphi 2010.

Also, any directions / instructions on installing the new indy components into my Delphi 2010 would be greatly appreciated.

Have you read the Updating Indy documentation in this repo?

Thanks for replying, I really appreciate it.
I'm also new to github, I was directed to https://github.com/IndySockets/IndyTLS-OpenSSL - and there were several links, I'm not sure which one I should use.
I will check out "Updating Indy".
Thanks again!

The IndyTLS-OpenSSL project has not been officially released yet. It will be part of Indy 10.7 (which is still a work in progress) and will remove the OpenSSL components from the main Indy library. At this time, IndyTLS-OpenSSL will be for backwards compatibility only and Indy 10.7 will favor TaurusTLS moving forward.

In the meantime, just use the current Indy 10.6.3 as it still includes the OpenSSL components built-in (IIRC, TaurusTLS does also work with Indy 10.6, too).

Thanks!!!!

Hi Remy, sorry to bother you again. It seems I have successfully upgraded the Indy components. The project that I actually use the Indy/ SMTP component is compiling fine - I haven't had the chance to actually test it yet. I was verifying my other projects are all ok after updating the Delphi with the new Indy components. I have a project that doesn't even use any Indy components, and I get an error as soon as I open the project. The error is, "the procedure entry point @IdGlobal@readstringfromstream$qqrp15classes@Tstreamip186sysutils@TEncoding could not be located in the dynamic link library c:\windows\system32\datasnapserver140.bpl" - this error comes up before the project is even open. ANy thoughts / suggestions on how to resolve this? Again, this project is not even using Indy components or specifically datasnap. Thanks, Joe

This is covered in the "Updating Indy" document, in the "Important Notes" section:

Delphi/C++Builder/RADStudio 2009-XE

Embarcadero's DataSnap framework is compiled against the Indy 10 packages that ship with the IDE. Installing a new version of Indy will render DataSnap unusable, as it will not be able to load the Indy packages anymore, and DataSnap cannot be recompiled by end users. If you need to use DataSnap, then you will need to maintain the original Indy 10 packages for use in DataSnap projects. You can use a separate installation of Indy 10 for non-DataSnap projects. This was addressed by Embarcadero in D/CB/RAD XE2 so Indy 10 upgrades and DataSnap can co-exist.

If you don't need DataSnap then you can simply remove it from the IDE.

Just an update to my previous post - it's always the first project I open up that gives the error. So the particular project doesn't matter, it's the first one I open after launching Delphi. After saying "ok" to the first error I get the error "can't load package dcldatasnapserver140.bpl" - and I "ignore this error" which then messes up the project, actually removing components.

Does your project actually use DataSnap? If so, then it will not be able to use the updated Indy. See my previous comment.

[joeifs814]

My project does not actually use datasnap. So my real confusion comes because a.) I'm not using datasnap and b.) the message referring to "dcldatasnapserver140.bpl leads me to believe that datasnap is part of INDY - and when you say remove datasnap from the IDE do you mean remove the "Embarcadero Datasnap Connection Components" from the installed package list?

[rlebeau]

DataSnap is Embarcadero's technology. It is not part of Indy, but it does internally use Indy. Indy is pre-installed in the IDE, and DataSnap uses the pre-installed Indy. That is why updating Indy breaks DataSnap, because in Delphi 2010 it is not possible to update DataSnap to use a newer Indy.

So yes, if you don't need DataSnap then just remove its components from the list of installed packages.

[joeifs814]

Sorry, but I'm losing my mind at this point. As suggested I have removed the datasnap components from the IDE - at least I believe I did. Delphi launches fine. But the first time I open ANY project I get the procedure entry point error referencing "windows\system32\datasnapindy10servertransport140.dll", and now a second procedure entry point error referencing "windows\system32\datasnapserver140.bpl". First off - neither of those files are in the "windows\system32" directory. I found them both in "windows\syswow64". After these 2 errors I get a third error stating "can't load package dcldatasnapindy10transport140.bpl the specified procedure could not be found". I "ignore this error and the project opens but it has been modified. I close project without saving. I re-open ANY project and everything works fine - no error messages! Projects all compile and run fine. So first time opening project after launching delphi get errors, any time I open the project after it works fine ... until I close delphi and start again. I can't seem to find why the procedure entry errors are looking for those files in "windows\system32"- but I think that is where I should start looking. And I don't know why it is still looking for datasnapserver140.bpl at all. Any help / suggestions would be greatly appreciated.

That sounds like your individual projects are referencing the DataSnap packages. You need to update your .dproj files to remove the references. Uninstalling the packages will stop the IDE from loading them by default, but each project can re-load them. The IDE allows package usage on a per-project basis so you don't have to clutter the IDE globally for all projects.
