@Cactus Dan:

ipconnection* ipc = GeIpOpenOutgoing(hostname, thread, ferr);?

How do you initialize the thread and ferr? Thanks
I try to catch the Bytes via WireShark Network Protocol, perhaps I get a little overview, how to control it.

Howdy,

Thanks.

In the meantime if we can't get a working example, an alternative might be to create a button named "Check for Updates" and then use the GeOpenHTML() function to open a web page in the default browser when the button is clicked. ;o)

Hi,

Unfortunatly I still can't provide you with an example. I have to do some more background reading about this subject (TCP/IP and all).

Yes, this is one of the questions in my mind, too. If you can give us some info about what thread we should use, and how to get that thread? Or do we have to create our own background thread, and how would we go about that?

If you can give us an example of that, maybe some of us can also do some studying and experimenting. ;o)

The thread can be a thread passed by Cinema, for instance in a videopost plugin, or your own thread. You would call for instance GeIpWaitForIncoming within the Main() of your thread and pass this. ferr is just a LONG that is filled with the error code, you should check for ferr != 0. The IP address for GeIpOpenListener() is encoded like this (take 127.0.0.1 for example)

Hi,

have you been able to send the e-mail finally? I still cannot. However SendMailAvailable() returns TRUE in my case. But I am unable to pass t_to parameter to the SendMail function. If I call it with NULL for t_to the default system mailer (thunderbird in my case) opens with right values for body and subject filled in. But as soon as t_to differs from NULL or empty string Cinema crashes. Does anyone successfully passed this parameter to the function?

Here is the code:

> String toadresa = "[email protected]"; \> if (SendMailAvailable()) { \> SendMail(String("subject"),&toadresa;,NULL,NULL,NULL,String("body"),SENDMAIL_SENDDIRECTLY); \> }

Thanks in advance.

Hi,

are there any news about the IP functions and their documentation?
I managed to set up a thread in C4D waiting for an incoming connection on a given port. When the connection is initiated, I call GeIpBytesInInputBuffer and GeIpReadBytes, but both always give me 0 as return, although I'm sending data from the other end. And as far as I found out, there's no way of telling that the connection dropped, since there's no function for asking about the connection status and the GeIpBytesInInputBuffer and GeIpReadBytes still return 0 after I closed the connection from the other side.

It am eager to use the IP functions, so it would be great if someone could help me out.

cheers

Is there any news about this? I wonder why it´s so hard to get an answer for this IP issue. I mean some programmer must have made this available and it´s only a handful of functions so why is it so hard to provide a code sample? Especially when so many people ask for it.

I´d really appreciate any info if this will be resolved or if the functions in the SDK are simply unusable in their current state.

All my attempts are leading to nowhere. I could establish a connection and even reading bytes does return something (though I don´t know what) but I have absolutely no clue what this tells me or how to use this for a real purpose (e.g. getting files from a server).

I am looking at external libraries now but if there was a chance to not rely on external libraries I definetly would.

Thanks

ok, I tried to send a HTTP command thru the established IP connection on standard port 80 but whenever I call GeIpWaitForIncoming, it never returns (passed listener is correctly established before). C4D idles and I can´t do anything anymore.
Do I need this at all? I am not fully sure I understand the listener intention but I thought it was necessary for getting the packages back. Is that so?

Sorry for not answering sooner. I'll try to get an example from the developers. Unfortunatly I have no knowledge about the workings of network connections myself so I can't answer directly.

PS. I'll address this asap in the new year. There is no chance for me to solve this over the holidays.

thanks Matthias. Here is example code I wrote which apparently doesn´t work but shows how I thought it would be working. Maybe it helps resolving this faster (or helps others to resolve with us).

With GeIpOpenOutgoing, you try to connect to someone listening.
With GeIpOpenListener you start listening yourself on some port, and when someone trys to connect to you, you get a connection.

Sending data worked fine for me, receiving should too.

I'll include a testserver and a testclient I did a long time ago, the server should display the message sent through:

IpConnection *con;
    con = GeIpOpenOutgoing("127.0.0.1:6000", bt, 10, 100, FALSE, &ferr);
    CHAR buf[7] = "blabla";
    GeIpSendBytes( con, buf, 7 );

on the same connection you can ofcoure also try to receive (wont work with my testserver though, since it doesnt send anything )

btw, it should always be a good idea to escape your sending/receiving buffer with '\0' or '\r\n'

testserver, written in c++:
it listens on port 6000 and accepts any connection, when it receives something it displays it.
