Socket packages

[Ole]

Hi,

Is there a way to prevent Socket from assembling the packages it receives?
short explanation:
I have an application A that sends like this:
for (i0; i<4; i++)
{
MySendSocket.se nd(sendBuffer, count, SocketFlags.Non e);
}

....and a receiving application that receives like this:
while(MyReceive Socket.connecte d)
{
noOfBytesReceiv ed = MyReceiveSocket ..Receive(recei veBuffer);
DoSomething.... ......
}

first time it receives 10 bytes but then it receives the last 30 bytes in
one package (noOfBytesRecei ved =30). So is there a way to force it to
receive the individual packages (the size is not necessarily the same in
each package)?

Thanks,
Ole

Re: Socket packages

Hi again,

Some sort of method to block sender would do it, but is such a method
available?:
while(MyReceive Socket.connecte d)
{
noOfBytesReceiv ed = MyReceiveSocket ..Receive(recei veBuffer);
MyReceiveSocket . BlockSender() <----- ????
DoSomething.... ......
}

Thanks,
Ole

The easy answer is that "No, you cannot".

You have to separate the messages by yourself. There are normally 2 ways:

1put the number of messages size as part of the header,so you know
exactly how much you want to read.
2use some delimiter like SOT (Start of Text), EOT(End of Text) to
separate your message.
