I want to know how we will manage memory while programing web applications and how to know if there is a memory leak.I have an application which gets data from a view available in sql server and refreshes the grid every 2 secs using Ajax UpdatePanel. This page runs all the time in the client machine.How can I check whether the memory is used properly when its run all the time and doesn't cause any memory leak problem or any system crash.

Iam trying to make a socket connection and am facing with the following error.
Socket tempSocket =new
Socket(ipe.AddressFamily,
SocketType.Stream,
ProtocolType.Tcp);
The tempSocket is connected to the particular IP and tempSocket.Connected is giving me value as True. But the property MultiCastLoopBack property is giving me the following error with error code 10042.
"An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call."
So is there any problem with the IP or Tcp is not supported with Stream as SocketType?

I've a project in C which acts as a server and accepts socket communication. The server project has multiple C files is an exe which accepts messages from the client program and responds accordingly. I've to write a Client program in C# which should open a socket communication and send a series of messages depending on the result of previous message sent.
Is it possible to send a message in such a way that it will call a function in one of the C file in the server project?

I wrote a small socket client application talking to my asp.net server application.
On the asp.net side, I created a IHttpHandler. I want to send data back and forth on one HTTP request.
I tried the following code which run an infinite loop inside function ProcessRequest(). The client side opens a socket connection and send HTTP POST request.
I am not sure how asp.net work. In HTTP POST I have to specify Content-Length, I tried a small value, like 20, then asp.net handler can only get 20 bytes in the inputstream. I tried to use 4096000 bytes(close to the maximum IIS allowed), then the inputstream cannot get anything, it seems IIS is waiting for all data(4096000) to come from client side before it gives the handler a chance to read from the socket.
public class DeviceDataHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
try
{
Stream inputstream = context.Request.InputStream;
Stream outputstream = context.Response.OutputStream;
/loop forever until exception is thrown
while (true)
{
ProcessData(inputstream, outputstream);
}
}
catch (Exception ex)
{
ZenLog.logError("DeviceConnector exception: " + ex.Message);
}
}
public bool IsReusable
{
get
{
return true;
}
}
}

I'm calling Another url from my web aspx page. I'm writing
[code]....
But I'm getting error
A socket operation was attempted to an unreachable host 208.101.14.59:80
I tried the same url by pasting it on address bar and works fine. When I call my vendor they r saying that there is no any problem from their side. Someone has suggested me that there may be some settings in web.config.

I want to send socket information to aspx page.eg. I have 80 clients connected to server. Server is doing some calculation based on the user input and if one of the condition is true, it will send the signal to all the connected clients. I'm the client. The other vendor is the server. Currently, my application is windows based, I want to change it to web based. So, When the server send the signal , I want to receive this signal from the web page.

We have a component that needs to sit in asp.net that creates a listening socket on a well known port.The reason we have the socket is the asp.net need component needs to received events from external services and other technologies weren't quick or flexible enough.We start the socket listening in application_start,and close the socket in application_end. The issue is if we are receiving http requests to the web site, and modify the web.config, the application_start event is called before the application_end is called,so we cannot open the socket (we get an error about duplicate socket being open). We dont have a reference to the original socket in the application_start after the web.config change, so we cannot shut it down from there.
