Thank you, - but it dident help me .. I still suffer this problem in Delphi 7 :

[Warning] sgcIdStackWindows.pas(1822): Return value of function 'TIdSocketListWindows.GetItem' might be undefined
[Warning] sgcIdIOHandler.pas(2630): Return value of function 'TIdIOHandler.WriteFile' might be undefined
[Fatal Error] sgcWebSocketsD7.dpk(225): Unit sgcWebSocket_Client was compiled with a different version of sgcIdTCPClient.TIdTCPClientCustom.SetReadTimeout

I installed Indy10 (downloaded from this/your site), and the indy-components are available on Delphi 7's palette, but still, I cannot install scgWebSockets.

I have searched Google a lot, but I find no clue as to what the solution is ...

Can you help/guide ?

Best regards

Hello,

The sgcWebSockets Trial already includes all Indy files required, because is the Enterprise version, which uses a custom Indy version. There is no need to install the indy 10 version (this is only required for Standard or Professional packages).
The error is raised because the linker find sgcIdTCPClient unit which is different from the included inside the trial/libD7 folder.
Just delete the Indy version installed (and all dcu, bpl...) and try again with only the Delphi 7 trial. It should work.

Kind Regards,
Sergio

Thank you a lot.

My misunderstanding.

The compile-process now halts at a missing unit instead .. "Threading" is missing.
I scanned my entire harddisk ... no "Threading.pas" (or .dcu) found .. What am I missing this time ? :-)

Best regards (and thanks in advance).

Hello,

It's weird, I don't make use of any Threading.pas unit... Indy only makes use of System.Threading if .NET (old version of Delphi...) is enabled, but in Delphi 7 it shouldn't be linked. I don't know, check the if some path is pointing to a wrong folder. I just installed the trial for Delphi 7 without problems, on a new machine.

Kind Regards,
Sergio

When trying to build program sgcHTTP2Client

This unit :

unit FHTTP2_Client;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ExtCtrls, ComCtrls,
sgcIdHTTP, sgcHTTP, sgcHTTP2_Client, sgcBase_Classes, sgcTCP_Classes,
sgcTCP_Client, sgcHTTP2_Types, sgcIdAuthentication, sgcWebSocket_Classes,
sgcWebSocket_Classes_Indy, sgcWebSocket_Server, sgcWebSocket,
sgcBase_Helpers, sgcHTTP2_Frame, sgcWebSocket_Types, Menus, Threading,
sgcSocket_Classes;

ABSOLUTELY does specify "Threading" as a unit (second to last line of the USES specification).

I am a bit confused, I wont hide that :-)

Hello,

Ok, I thought the problem was installing the package not a demo.
Yes, the demo uses the Threading unit because creates a thread for HTTP/1.1, but this unit is not included in Delphi 7.
I've deleted the references to this unit and all the HTTP 1.1 code (so only HTTP/2 will work). You can download the modified project from:

https://www.esegece.com/download/samples/http2_d7.zip

Kind Regards,
Sergio

I understand your confusion.

Both actually.

I work for a company that is considering purchasing your WebSockets components, and we have a large portfolio of Delphi 7 software that we MUST maintain.
Personally I work with Delphi 10.4.2 (and 11) where the server-suite will be developed. But before management will allow me to set the plan in motion, I have to document to them that I can make the client-implementation work with the old Delphi 7 products.

Your new demo-project with the removed Threading unit compiles well .. and I am now testing it up against the server-setup compiled in Delphi 10.4.2

If everything turns out well, we will become a new customer with you ..

Thanks for your help and time !

Hello,

Glad to hear it works now.
Just contact me again if you have any problems or concerns.

Kind Regards,
Sergio

Hello Sergio,

thanks for your fast reply.
I am Testing it for TsgcHTTP2Client.

FClient_Request.Proxy.Port := 16041;

Yes, first returns a 407 error and then connects again using credentials and the connection is successful, it's correct. Find below the log:

Hello Sergio,
can you please let me know when will the next release be published?
And the next question: what was the problem?
Thank you in advance.

Best regards
Artem

Hello,

Most probably there will be a new release this month.
The problem was related with the TLS handshake.

Kind Regards,
Sergio
