Okay, I am not familiar with this and a bit of googeling gave me this information: Winsock Error[^] and WSAENOBUFFS errors in Tor[^]:
An operation on a socket or pipe was not performed because the system lacked sufficient buffer space or because a queue was full. WinSock was unable to allocate additional memory to accommodate the function request. This error indicates a shortage of resources on your computer.[...]
I am just guessing here. If this indeed a resource problem, can you try to close unneeded applications (also make sure you do not have a memory leak in your application) and alternatively run your software on a PC with more RAM? Another way to diagnose the problem, limit the server to 100 connections and then increase the value until you hit the problem (keep an eye on the overall system memory consumption e.g. with 'Windows Task Manager').
Hope this helps...

ya I have 2GB ram on the system and task manager shows PF usage = 1.35gb

What does that mean, problem solved?

Are all the clinets are on the same network/subnet?
Are you unicasting or braodcasting?
Can you ping each client machine from the server?
What is the ARP cache like on all the machines?
Are the network cards/drivers on the machines set up to accept braodcast packets if broadcasting?

no they are on internet on different ip address
Are you unicasting or braodcasting?
I do not understand simple TCP/IP and want server send data to all clients
Can you ping each client machine from the server?
no not at all server at public IP client IP I donot know how to get but can ping server from every client
What is the ARP cache like on all the machines?
can you help me in this scenerio

Are they all directly on the internet or are they hding behind NAT? If so you need to makwe sure you have NAT traversal enabled in the proxies.
A Broadcast address (255.255.255.255) is for all devices on the subnet. A Unicast address is for one machine.
If you cant ping I dont see how you can sockets to work.
ARP is hardware to IP address mapping. If you are on a LAN this is important, and thats the normal place to use sockets. On a pure IP backbone ARP isnt used of course.
Ditto the network cards.
And you say on some machines the sockets work. Hmmm.... client to server, or server to client (ie which is the watcher and which is opening the socket)?
Even on th eones that work, ie the watcher can accept an incoming socket open, can it respond sucessully with that response arriving at the initiator?
I think NAT is going to kill this dead. You need to have NAT traversal at least to have your clients IP addresses public enough to be visible to the server.

answer : they all are directly on the internet

answer : This is not Broadcast sure . I donot know unicast
If you cant ping I dont see how you can sockets to work.
answer : server on public IP you can ping any where from world no proxy nat at all
ARP is hardware to IP address mapping. If you are on a LAN this is important, and thats the normal place to use sockets. On a pure IP backbone ARP isnt used of course.
answer : I think there is no need
Ditto the network cards.
And you say on some machines the sockets work. Hmmm.... client to server, or server to client (ie which is the watcher and which is opening the socket)?
answer : server on public IP is listener . and client on any where in the world open socket communication with the server with IP and port number
Even on th eones that work, ie the watcher can accept an incoming socket open, can it respond sucessully with that response arriving at the initiator?
answer : it respond succesfuully with the server
I think NAT is going to kill this dead. You need to have NAT traversal at least to have your clients IP addresses public enough to be visible to the server
answer : on one timer tick (usually 100ms) any client get the data and on next tick donot get and again get on next tick . this is happening randomly with all clients ,and I am sure all clients are connected sussefully to the server.

So all are on the internet, in which case you CAN ping from server to client.
And ALL clients receive data, but only occasionally, depending on the tick? # (This is different to what you wrote initially)_
I cant really provide anymore help. If the basic IP route is up then you should be OK.
All I can suggest is sniffing the data at the hardware level, make sure it is there, ie conming and going. Etherreal type products are good for this sort of stuff.

hi,
how do i use string compare to get this value
<span class="streaming-datum" id="yfs_l10_^ixic">2,190.06</span>
before that line of code,there are many other html codes before and after it.
my friend suggested to me using string compare this string "<span class="streaming-datum" id="yfs_l10_^ixic">" and if the compare value is true, do a loop and loop through the remaining text till i get a '<'
but how do i continue looking for the value after &lt;span class="streaming-datum" id="yfs_l10_^ixic"&gt;

You probably need to start by parsing the HTML and looking for entries with one of the keywords e.g. span to narrow the search. This article[^] may be able to help you.

Not that I know of; you could try Google to see if there is a better option. Alternatively you write your own, I have done this in the past but it is not a simple task, much better to leverage what others have already done.

Well, if I undestand correctly, he could leverage what you have done in the past...

Unfortunately, what I did in the past was for my ex-employer, and they kept all (rights to) the code.

I have seen menus in MS word 2002, they hide unused menus and display them only when you move to the dowble arrow shown at the bootom of the menu. How to implement this feature in a MFC application?
|
|
|
|
|
|
No. That MSDN page is about Toolbar. I'm looking for menu. Similar to MS word menus or Windows XP Start-Programs menu.

Handle WM_INITMENUPOPUP, see CWnd::OnInitMenuPopup in your doc.
cheers,

Let me elaborate my requirement. I want to hide the menu items which are not used often by the user. Show only the menu items which are frequently used. Provide an arrow (MS word shows two down arrows one below the other) as last item in menu. When the user places his cursor on this arrow show all menu items. If user clicks on any item which was hidden, bring it to frequently used list and show it by default next time.
The implementation wil be:
I have to track all menu clicks of user and store them along with date and time. When it becomes one month old move it to rarely used list. I may have to use a database or a data file.
Show an arrow (how?) when some items are hidden.
Show all items when the cursor is on arrow (not on click) (How?)
As I have to start the project from scratch, I'm looking for some inputs who has already implemented so that I can implement in optimized way.

I suppose you have use owner drawn menu option to design your menu.

If you are using Visual Studio 2008 with the Feature Pack (new ui stuff) you can use CMFCMenuBar::SetRecentlyUsedMenus for individual applications.
There's a setting in the for the taskbar/start menu that, I think, set the global behavior for all applications.
(on vista, so it might not be the same on XP or W7)
"Control Panel" -> "Taskbar and Start Menu" -> select "start menu tab" :
If you select the "Classic Start Menu" and click on Customize, you can check/uncheck the last option in the list "Use personalized menus" to change the behavior.
Google for "personalized menus" for more informations.
