Hello at all

I want just to know if there are a limit for the size of the file sending with SendNetworkData ???

For the moment, that's works with 5 mb, but i want to be sure this simple method is safe

For example, can i sending a full movie of 650 Mb with this simple code, or i'm forcing to cut the movie in several piece for sending it ??

Code:

File.s = "The ReturnOfKCC.avi"
FileSize = FileSize(File)
Buffer = AllocateMemory(FileSize)
SendNetworkData(ID, Buffer, FileSize)

Thanks and good day

no you can not,

max buffer size of you network send buffer (in windows, not in PB) is ~128MB (in my system)
So you must send it in blocks.

btw: you do not allocate 650MB in you RAM, or?

How you find this number, for be sure use the better (not too big, not too small) ????
Because i suppose all the system is not the same ????

Note:
SendDataNetwork sends the data not to the other, only into the transmit buffer of the network card, the buffer size is somewhere in your system configuration, or you have to try it yourself.
If SendNetworkData returns -1, the data is to long :wink:

It is recommended in any case that you send only small blocks, and then waiting of a feedback from the other, whether it has arrived, and then send the next.

the PB help say TCP (over netzwork) can send/receive 65KB per transmission.
