Jpg,Gif Over winsock.

[JohnStep]

Anyone know the best way to send a Gif or Jpeg over winsock without using FTP? Is there anyway your basic IP stream?<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sincerely,<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;John Stephens

JohnStep -<br><br>How complex do you want the answer to be?<br>&lt;g&gt;<br><br>If you're only dealing with Windows/Intel PCs, then you won't have to worry about translating the bytes into network order (so they can be read by Motorola/other CPUs).<br><br>Is the client a web browser?&nbsp;&nbsp;If so, then you have to delve into the mysteries of HTTP. (basically, surround the picture bytes with the correct codes to allow the user's browser to recognize it as being a picture)<br><br>Otherwise, it's just bytes.&nbsp;&nbsp;The only gotchas left is you <b>must</b> remember that in TCP/IP, it's a stream of bytes.&nbsp;&nbsp;Any concept of record length, or data length, has to be added by you.&nbsp;&nbsp;The protocol will not preserve record boundaries (this must be the #1 question on the Winsock mailing list).<br><br>Chip H.<br>

John,<br><br>Why bother? If you don't use ftp you will have to write both ends of the program - one to send, one to receive. You will have to implement error checking, pass the filename(s) across - all kinds of stuff that ftp handles perfectly well.<br><br>Is ftp not available at the other end? I would have thought that it TCP is available then FTP will be as well. If you have to buy it then - buy it. That will be cheaper than writing the thing yourself.<br><br>Have a look at the Internet Transfer Control that comes with VB.<br> <p>Mike<br><a href=mailto:Mike_Lacey@Cargill.Com>Mike_Lacey@Cargill.Com</a><br><a href=
