The closest thing I found was this: http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=115597[^], but it's old and for beta.
Since for example led mike couldn't reproduce, the code that worked for me didn't behave as expected for you, could this be an installation issue
I used (plus several hotfixes):
Microsoft Visual Studio 2008
Version 9.0.30729.1 SP
Microsoft .NET Framework
Version 3.5 SP1
Edition: Professional
on Windows Vista SP1
The need to optimize rises from a bad design.

As near as I can tell, I don't have VS2008/SP1 nor DotNet 3.5/SP1 installed on this system...
I'll try the same code at home and see what happens...

lets say you set an initial byte[] size to 30 and the message that you receive has a size of 50. How would you handle that with Socket.BeginReceive
With Socket.Receive this would work:
byte[] buffer = new byte[30];
int size = Socket.Receive(buffer);
String msg = Encoding.ASCII.GetString(buffer, 0, size);
while(size > 0)
{
buffer = new byte[30];
size = Socket.Receive(buffer);
msg = msg + Encoding.ASCII.GetString(buffer, 0, size);
}
How would you do the same thing with Socket.BeginReceive?
Thank you,
Prateek

use the overloaded receive method that takes in an offset, and a length to read. Also, don't redeclare the buffer as it is unnecessary.
int read = 0;
byte[] buffer = new byte[255];
while( ( read = socket.Receive(buffer, 0, buffer.Length)) != 0){
... Encoding.ASCII.GetString(buffer, 0, read);
}

Thank you for your suggestion... i know how to do it with Socket.Receive. I wanted to do this with Socket.BeginReceive. The problem is in order to get the first part of the msg, you'll have to use Socket.EndReceive and then how will you get the rest of the msg?

Begin Receive contains a similar overload as receive. The logic is the exact same, except in the callback method you must call BeginRecieve again after reading all of the bytes.

so just for clearification the code would be something like this:
int size = socket.EndReceive(iasyncresult);
while(size > 0)
socket.BeginReceive(...);

no. read the MSDN.

ok. Thanks for your help

If anybody is looking for the answer, do check this link [^] out.
Also, be careful with the ReceiveTimeouts. ReceiveTimeout is for synchrounous receive only. So, if you don't want your loop to get stuck, make sure you include some way of identifying the end of message.
Good Luck,

I am currently writing UDP socket class to control a device. I created a class that has a UDP socket. I have blocking function that I uses the socket to transmit a packet to the device. The function than needs receieve the response packet/packets from devices. However, if no valid response is not recieved in x period of millisecond the function needs to timeout. I am having difficulties creating a way to calculate millisecond periods. In the past i use to use GetTickCount(); How do i accomplish this i C#

Create a timer and use the following event:
int tickCount = 0;
void timer1_Tick(object sender, EventArgs e) {
tickCount = tickCount + 1;
}
I haven't tested the code out, but it should work. Hope this helps

The .net timers are not all equal and do not all perform as you might expect, especially in terms of resolution. Luc Pattyn has a great article on timers here[^] that may help - if not, it's a good read anyway 
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

Huh? Do you mean CLR? You could always take a look at FxCop, though it is more for checking coding standards.

No, I mean CER: Constrained Execution Region.
