Martin,
Send me a PM and I'll send you a really small Telnet pgm that I use as my "starter" program for telnet like apps...

Transmit large data with buffer
Hello Erel,
I got a question according to your post with that server application example.
You wrote a function/routine which receives data over a buffer so that the data can be very large although the buffer is very small. There are lot of annoying things done in this dowhile-loop. Is it possible, (has basic4android the ability) to receive data just by doing something like calling a receive function, so that i dont have to care about all the buffer size- and file size- stuff like checking the size of the inputstream and counting the bytes, that are already received?

Which code are you asking about? Why is it annoying to deal with buffers? The only difference with an internal function is that the annoying stuff is not visible.
You can use File.Copy2 to copy one stream to another without seeing the annoying implementation.

Okay thanks a lot!
I just wrote my own serverapp in B4A and i built a client in C# and it works well.
But now i tried to build this client in B4A and it works while sending a small text (smaller as the buffer size) but can you post me an example how to transmit a text larger as the buffer? For example just some words in a string with a small buffer Dim buffer(2) As Byte?
That would be very helpful cause i dont know how to handle with the inputstream size and the code for piecewise filling/reading from the buffer.
Thanks a lot!

You can use File.Copy2 to handle the transfer. You can convert a string to an input stream by first converting it to an array of bytes with "some string".GetBytes and then use InputStream.InitializeFromBytesArray to create an InputStream. Basic4android - Files (Core)
Hi all,
I am a bit lost. Looking at this site for 2 days, I still find it difficult to use this library. What I am looking for is to connect to a server on another machine and be able to send and receive text through a TCP socket.
Unfortunantaly the examples I find are either a server to receive files, or a client that just receives info from a NTP server.
Where can I find the documentation that describes the events that can be fired ? In the examples I find the connected event, but once connected what is fired if you receive data on the socket ? Or do I use a timer and check every so often ? How can I send data through the outputstream method.
Thanks to anyone who can help me.
Wim.

There are several options. Probably the best one is to use AsyncStreams: Basic4android Search: AsyncStreams
Note that you should not use prefix mode unless you control both sides and can implement the required protocol.

Hi Wim213,
this is exactly what I am looking for. Just sending a simple string to a TCP server. That's it. But so far I am fighting with the tutorial without success. Do you have meanwhile the information you needed? If yes, would you please share the outcome, so that I can profit from that?
