I didn't found any performance counter that would monitor an process's/thread's network bandwidth and not just that of an ethernet card.
So I could see how much bytes did an application receive and send.
Did I miss something or is there another way?
is it possible to make one application send a task to another application and recieve the result from that secondary app?i made a text editor program and i added a scan feature and i made another app that has ocr capabilities.The scanner ability is in my text editor program, the ocr program doesnt scan you have to input an image into it and it will give text result a few seconds later.the prob is alot of times the ocr code uses sooo much memory and crashes when its incorporated with my text editor, but individually each application works fine and doesnt take too much memory. Memory wont be even an issue if the ocr program is standalone so that when it is done decoding image the application can be made to exit. now here is the question, how do i make my text editor send the image to the ocr program and how do i make my ocr program send the text back to my text editor? is it possible? i mean the only way i know off is creating temp files in a certain folder and having a timer on each program that keeps waiting for temp files. That just seems like pretty lame coding to me i was wondering if there's a better way?
View 11 RepliesI have created an application which listens for strings being sent to my pc from a remote unit. I now need to add the function of sending strings back to the remote unit on a button press. I've searched for ages to find a solution but I'm not knowledgeable enough yet with vb.net to solve this solution.
I'm getting the error with the line opensock2 = New IO.StreamWriter(client.GetStream) saying its not connected. So I seem to need to pass the connection from the background worker to the button click, or have it somewhere else in the code to make it accessible. [Code]

View 1 RepliesI'm trying to send a 28 character string to a remote ip address and port. I've done this successfully in vb.net using the following code snippets:
Dim swon As String = "A55A6B0550000000FFFBDE0030C8"
Dim sendBytes As [Byte]()
sendBytes = Encoding.ASCII.GetBytes(swon)
netStream.Write(sendBytes, 0, sendBytes.Length)
I now have to convert this across to c++ and have the following so far:
char *swon = "A55A6B0550000000FFFBDE0030C8";
array<Byte>^ sendBuffer = gcnew array<Byte>(bufferSize);
sendBuffer = BitConverter::GetBytes( swon );
tcpStream->Write(sendBuffer, 0, sendBuffer->Length);
but am getting stuck at this point. I'm sure I'm missing a simple syntax error but I can't figure it out!To clarify, I'm not getting an error, but I don't think the string is being converted to bytes correctly as when I convert back, I just get a '01'
first asking an question and then introducing but i kinda need some help in here.First of all im not new to VB, But i am to VB.NET and espessially socket programming.Now i need an way to send the lenght of the string being send in bytes before the string itself so <lenghtinbytes><string>.
ive tried so many things, and its possible because the client itself does it too...but just cant find an way.

I would like to use the USB port power as source and use the an amplifier on D+/D- Twisted Pair signal wires as my command line. I saw a thread suggesting to use the output as PWM. How can I send a single byte or stream of bytes to the port. Is it possible to read status of the D+/D- if they are shorted together?

View 1 RepliesI need to send and receive a large image between programs running on different machines within the same network.
I've looked at using upd however ran into problems with the size of the packets and
(after breaking the image into smaller pieces to get past this problem) the number of packets needing to be processed all at once - and ultimately packet loss.
I've also thought of sending the image by storing it in a common file folder and receiving it by using file watcher as a trigger. However, this just adds further complexities in setup where common folders don't already exist.
Assuming I'm barking up the right tree looking at tcp, can someone point me to/provide an example of how to send an image file using it (vb.net would be ideal). Also, are there practical limits to tcp package sizes?
I have these following lines to send bytes using socket

I'm using asynchronous to send/receive from a website I want to block the BeginGetRequestStream method which I have done, using
Code:
WaitEvent.WaitOne(1000 * 20, false);
the problem is that it blocks the UI, which I thought it did not so it basically works like GetRequestStream which does block the UI.

I coded a small tcp server/client software implementing the async methods of the socket object. In order to keep track and control of the transfered data on both sides, I decided to wrap the bytes to be transfered into small 65 000 bytes packets, sent one after each other, in varying order.In most cases, it works perfectly, and it is impressively fast. However, when I want to transfer larger data than my usual requests, say like a dozen megabytes, crippling problems start to appear, out of shit.Effectively, it seems that somehow when executed without pauses, the server sends the packets too fast, or that the client receives it too slowly. However, if I put the SendAsync method's thread to sleep for like 100ms before sendingthe next packet, everything arrives without problem on the client.[code]

I am using sockets and such for a while now, and want to go an step further in this. Now for example lets say an client would send [lenghtofstringinbytes]string[somethingelseinbytes]another thing.
How can I send/read/parse it?
Now I am doing this:
Private Sub onDataArrival(ByVal ar As IAsyncResult)
Try
Dim obj_SocketState As StateObject = CType(ar.AsyncState, StateObject)
Dim obj_Socket As Socket = obj_SocketState.WorkSocket
Dim sck_Data As String
[Code] .....
So using Getstring for it, but thats not the way for this as you get nothing else but an empty string back. So I have to parse it without converting it to an string.
