  1. First let me preface it by saying I use ICS with C++ Builder 12 and not with Delphi. I apologize if this is not the right place to talk about my issue but it is the most active place I found discussing ICS. I am trying to build a very simple TCP server using a TWSocketServer accepting connections from TWSocketClient. I have coded such a server on C++ Builder XE8 with ICS 8.47 and it works just fine. However, I am in the process of upgrading to C++ Builder 12 and to ICS 9.4 and it is where my issues start. The server starts fine, and when I try to connect a client, I get the event and the client is accepted. However, when I check the client data in the debugger, everything is set to NULL. And after this first connection, my server doesn’t receive any other event, whether it is other clients connection, the deconnection of a client or any data that a client might send. Does someone have any idea what could cause this ? I have enclosed my .h and .cpp files but it is very basic. Unit1.cpp Unit1.h
  2. I have tried it but unfortunately, the Client object is still the same. For it being easier, I am now doing all the tests of the c++ version of the OverbyteIcsTcpSrv sample.
  3. Yes, I have tried that at first and it doesn't solve the issue unfortunately. The object that is empty is the Client : TWSocketClient, casting it into another custom class or not has no impact
  4. My issue is that on the WSocketServer1ClientConnect function, I am supposed to receive a TWSocketClient* object that is then cast into a TTcpSrvClient*. For Delphi it is equivalent to the Client object passed here : procedure TTcpSrvForm.WSocketServer1ClientConnect(Sender : TObject; Client : TWSocketClient; Error : Word); and then the case into a TTcpSrvClient* is similar to this with Client as TTcpSrvClient do begin. The issue is that the TWSocketClient* that is passed to my function seems to be badly initialized as all its properties are set to NULL or are empty. In the screenshot below, I have set a breakpoint in the WSocketServer1ClientConnect function function and on the right in the debug inspector, you can see the properties of the Client object that is passed, which are mostly set to NULL or default values. In particular FPeerAddr and FPeerPort are both NULL. The result of that is that I cannot communicate with the clients from the server afterwards and I also don't receive any other event (connection, deconnection, data sent...) And as you can see, when the client connect, I don't have any info about it : While when I use the sample executable directly (which I think must be compiled from Delphi), I have the correct informations about the client
  5. Sure but for now except understanding that the TWSocketClient is empty when passed I haven't been able to successfully log anything as my server appears stuck after. Notably, I can still successfully connect with clients but don't receive any connection event on the server side. So it was more about looking at the logs in the TIcsIpStrmLog.pas to see if I can add something I missed. Yes, I looked at the .pas files for OverbyteIcsTcpSrv both in the 9.4 release and here : https://svn.overbyte.be/svn/icsv9/demos-delphi-vcl/OverbyteIcsTcpSrv1.pas 9.4 release is almost identical to the .cpp samples baring some additional logs. And based on the last version of the file, I have implemented an OnClientCreate event, but the TWSocketClient * passed to this function is empty as well.
  6. Thanks, I will try to convert it from Pascal to C++ in order to log all information and see if I can understand why the TWSocketClient *Client that is passed to my OnClientConnect function is basically empty. I have also found this topic that is awfully similar to what I am facing, maybe they will be able to help me :
  7. Hello, it has been quite some time but I am encountering exactly the same issue as you, except with the TWSocketServer component when I try to create a very basic TCP server. I receive an OnClientConnect event when I try to connect for the first time but then, just like in your case, the TWSocketClient * that is passed to my function appears to be unitialized. And then my server doesn't handle any other event. Have you found the root of your issue or a way to circumvent it ? Thanks in advance for your help
  8. I have tried to connect to my original server using the RemoteSocket component. However I have the same issue that I had originally, the connection event is detected but the client appears not to be initialized. As a result, I don't receive any of the data I send from my server, getting this error on the server side :
  9. I am not sure to fully understand ? Do you mean testing this client against the server I coded originally and wasn't working, in order to test if the issues were linked to the clients or to the server ?
  10. I receive the same kind of data when I switch to port 21502 and deactivate SSL so it appears to be working as well. Additionnally I have checked that the lines that I receive with my code on the SSL port is the same as what is received through your own snippet tool
  11. I translated it to a C++ Builder 12 project and it appears to be working, or at least I get output similar to what I am getting from the .exe snippet
  12. Thanks for the link, when I use the .exe directly it works fine both with OverbyteIcsTcpSrv.exe and OverbyteIcsIpStmLogTst.exe But I have tried recompiling the the OverbyteIcsTcpSrv from the cbproj file in the demos-cpp-vcl folder and here it doesn't work. I am at a loss for why but I will keep investigating, thanks for your help
  13. Hello, Thank you for your answer. Yes it is running ok for ICS 8.47 / C++ Builder XE8 but not with ICS 9.4 / C++ Builder 12. The project I enclosed is just a simple project I did to test ICS components. I was in the process of migrating an application from C++ Builder XE8 to C++ Builder 12 when I noticed that some of my implementations using ICS were no longer working. I haven't found the OverbyteIcsIpStmLogTst in the demos-cpp-vcl folder, only in the demos-delphi-vcl and unfortunately, I don't have delphi on my version of C++ Builder.
