these actions might accure simultaneously wich would resolve in an exception such as argument out of range exception , when the collections counter is being redifined.

How and why to reuse socket with Socket.Disconnect( )?

Socket.Disconne ct(bool reuse) according to msdn enables the program to reuse the socket
my questions are:

1)
if we decide to reuse the socket does that mean it will reuse the same local end point as well,what i'm asking is,
would it preserve the port for that socket or would it just(i don't believe it does)
save all the objects resources ?

2)if in effect it does only save the resources...

Control.Invoke() vs. Control.BeginInvoke()

first of all,i would like to apologize for my bad grammar since English is not my native tongue.

To my understanding :

Control.Invoke( delegated_metho d) // Executes on the thread wich the control was created on
witch holds its handle ,typically this would be the main thread of a winform application .

Control.BeginIn voke(delegated_ method // Executes asynchronously on a threadPool Thread ....

SocketOption ReceiveTimeOut

now lets take a secnario where we use a locking socket receive and the packet is 5000 bytes with receivetimeout set to one second

s.SetSocketOpti on (SocketOptionLe vel.Socket, SocketOptionNam e.ReceiveTimeou t, 1000);

int bytes_recevied = 0 ; byte [] ReceiveBuffer = new byte[8192] ;

Socket Send/receive simultaneously

can any one point out the reason why u cant send and receive on a socket at the same time ?

to my understanding there are 2 streams one to push and one to pull

if you attempt to send/receive simultaneously you will get wasealready error

what is the reason that the socket throws wasealready error (10035)
does it have any thing to do with the ack window the receiving side sends back ?

How to fix "file is being used by another process" errors?

I've got a problem wich cant manage to overcome although it might seem fairly simple. I've got a chat program, in wich i want to enable users to change user pics at runtime. There's a picture box winch is set to an image with the name of a certain peer for example : "C:\\FriendLy\\ Users\\eran\\Pi ctures\\eva.jpg "

Now what i need is to replace this picture and override it. The first thing i do is copy it to a new location...
