I'm not sure which changes you refer to. Do you mean not sending a banner?
I've looked at the archives in case I missed a message. It looks like I
didn't, but I'm not sure what you're referring to. I think I've somehow
missed something.

My purpose for translating socketspy was to just get it working in C++. My
intentions are to create a component that does what socketspy does, but it
will be used strictly with NNTP. Sorry I didn't mention that. I know the
logging to a richedit dramatically slows the redirection. That's just for
testing.
I want to build a simple NNTP proxy. However, I only need to intercept the
POST command and then grab the message. I've done this and I've found it
easy to accomplish. Do you think this slight variation of socketspy is
actually useable, or do I need a more robust proxy? I was unable to find a
NNTP proxy in Delphi/Cbuilder anywhere. I do like the simplicity of
socketspy. I could build on it if I should need more in the future.

Thanks so much for this info, I'll sure fix that immediately.

Re: [twsocket] SocketSpy to C++ Problem
Hi Arno, I was looking over my project and see that the processmessages loop I said allows the program to complete successfully is enabled. To allow the error this needs to be commented out.

Re: [twsocket] SocketSpy to C++ Problem
Hi Arno,
I took out the banner and still the error. I took out banner and
bannertoobusy (individually and both together) and neither made difference.
I also commented out all logging last week and no difference from that
either.

[twsocket] SocketSpy to C++ Problem
Hi All, Sorry again, Francois told me and I missed it. https://www.quicksilvermail.net/socketspyc.zip I have done a cbuilder translation of Mr. Mestdagh's SpocketSpy program. But, I have a problem. When I run the program and try to connect with a server, I get this immediate error: "An unknown response was received in response to a request for information from the news server 'SocketSpyC++ Local TCP Proxy'" Under the details button of the error dialog, I get: SocketSpyC++ Local TCP Proxy Configuration: Account: SocketSpyC++ Local TCP Proxy Server: 127.0.0.1 Protocol: NNTP Port: 119 Secure(SSL): 0 Code: 800ccca0 I don't have any idea what the problem is. First, while trying to debug, I put a popup messagebox at the end of the WSocketServerClientConnect procedure to take a look at a variable. What I discovered was that messagebox being open allowed the program to actually connect and go further before error. After that, I replaced the messagebox with an Application->ProcessMessages() loop as a test. I was amazed that after that, the program ran completely and reliably--everytime. It works just great, but I haven't tried more than 1 connection because of the ProcessMessages loop. Though the loop has been helpful, I doubt it is the appropriate fix for this. My socketspyc project is attached. Please have a look. The ProcessMessages loop is at the end of the WSocketServerClientConnect procedure.

[twsocket] SocketSpy to C++ Problem
Hi All, My apologies. When the list sent my message to me, there was no attachment. I'm going to try again in case I screwed this up. If it arrives without it please tell me how I'm to include my project. I have done a cbuilder translation of Mr. Mestdagh's SpocketSpy program. But, I have a problem. When I run the program and try to connect with a server, I get this immediate error: "An unknown response was received in response to a request for information from the news server 'SocketSpyC++ Local TCP Proxy'" Under the details button of the error dialog, I get: SocketSpyC++ Local TCP Proxy Configuration: Account: SocketSpyC++ Local TCP Proxy Server: 127.0.0.1 Protocol: NNTP Port: 119 Secure(SSL): 0 Code: 800ccca0 I don't have any idea what the problem is. First, while trying to debug, I put a popup messagebox at the end of the WSocketServerClientConnect procedure to take a look at a variable. What I discovered was that messagebox being open allowed the program to actually connect and go further before error. After that, I replaced the messagebox with an Application->ProcessMessages() loop as a test. I was amazed that after that, the program ran completely and reliably--everytime. It works just great, but I haven't tried more than 1 connection because of the ProcessMessages loop. Though the loop has been helpful, I doubt it is the appropriate fix for this. My socketspyc project is attached. Please have a look. The ProcessMessages loop is at the end of the WSocketServerClientConnect procedure.
