MSCOMM: SENDING & RECEIVING BINARY FILE PLEASE HELP...

[vijithamar]

Hi friends,

Please help me in using MSCOMM control for sending & receiving binary files along with file name.

In my Programm, user will select the file-name and send the file, The receiving computer will save the file in the same name.

my problem is this, When i am sending the file in single byte (byte by byte using a loop) it taking lot of time to complete a file. And I can’t make out in receivable computer that the received byte is a part of file-name or the file itself

Please explain me. How to send and receive the data in packets. And how to flag it start/end of file-name or start/end of file.

Thank you,
Regards.

The first thing you send is how many bytes that are being sent as filename then how many as the file itself.


Two strings walk into a bar. The first string says to the bartender: 'Bartender, I'll have a beer. u.5n$x5t?*&4ru!2[sACC~ErJ'. The second string says: 'Pardon my friend, he isn't NULL terminated'.

Well the first 8 bytes that you send would be two long values the first being len("amruth.exe") then the 6,160,384.
