Q: sending images over a network?

[c++er]

I am working on a program about motion detection that a server side appl captures images when motion detected then it sends these pictures to a client appl.. I know that Winsocket is used for sending text but I dont know how to send images over the net!

c++ code if possible

It's not going to be much different from sending text. Just send the actual file data instead. Remember, you may need to send a length notification so that the client knows when it's received all the file.

you need to break up the file, then send segments, recompile them at the other end, pretty easy.

just open the picture for binary, and make a loop 1 to lof(filenumber) divide it into 1 kb segments, add a header and footer for each segment, an overall checksum and length.

Client>Serv "About to send file"
Serv>Client "Start Sending"
Client>Serv "Length, Checksum"
Client>Serv "BOF"
Client>Serv "SegmentNumber,HeaderData),length"
Serv>Client "Confirm SegmentnumberX, SegmentX Length"
If it doesnt match the buffer, resend
loop till end
Client>Serv "EOF"
Serv>Client "File Checksum Ok, Length Ok"
