It is because you are adding the seconds row parameters to the existing list or command parameters. Try creating your cmd instance inside of the for loop

Why 2 bad answers?!?
The OP question only asks WHY it does not work - which I answer exactly. It does not say tell me the answer and give me a solution. Because that would be a HOW question

Putting the required DLL into GAC may solve this problem.
Just try for it.

What a strange question I've ever seen.
If you are going for windows application then use WinForms and WebForms for web application.
That is not like when to use that is by choice of people Either they are devloping web or windows apps.
Usually people are using WebForms because they want to make people to see that from the M/C connected through network rather then installing WinApp on every PC.
Your question should be of WinApp vs WebApp.

Hiren.

Webforms: originated from the evolution of the web.
winforms: WinForms on the other hand originated from VB, MFC and other desktop environments.
If you use Winforms, you begin having a deployment problem. You either have
to have everyone update their machine everytime you update the application,
or you have to use ClickOnce. Depending on how complicated your application
and deployment scenario would be, clickonce may or may not be an option. You
will need to make sure your users have .NET 2.0 installed (clickonce can do
this for you, I believe). Because this is an internal application only and
will not be redistributed, it may be easier to implement this.

I've no problem with you quoting from other sources, but you do need to respect copyright law and provide a reference to the original material. Just a "Read more here..." link would be perfect, and extremely helpful.

Hi!!
Hello every one...
I wanted to know what should i do to keep on listening to multiple ports for msgs and displaying on respective text boxes.
i've tried asych sockets. but cant get it right..
it listens for only one time. if i start a while loop the whole app stops responding..
i hope threading is a answer but i know nothing abt it..
plz guide me..

Hi,
1.
the question is unclear. What ports? TCP/IP ports? SerialPort instances? ...
2.
regardless, you can handle that with either asynchronous methods and events, or by having some kind of thread and a blocking read.
3.
in any case, you can't touch GUI Controls from threads other than the main thread. So don't try myTextBox.Text="got something"; inside a DataReceived handler. The solution is here[^].

Ans 1. TCP/IP Ports...
Ans 2. How can i use Threading in GUI app??? i've textbox1 and textbox2. now i need to listen port port1 and port2 and direct the received msgs to their respective textboxes.
Ans 3. thanks for that.. i've studied it already.. that cross thread funcs..

threading is the same in all kinds of apps, whether GUI, Console, or headless. However to access Controls you need to Invoke.

I don't see a specific question here. if you are not familiar with the subject, read up on it, think about it, and experiment. when stuck, ask a specific question.
ayandelhi wrote: how much time does it take
42 msec.
how long is your message? how fast is your LAN? what other traffic is there? how inefficient is your code?
if you now some app that does things similar to what you want, then that proves it can be done; if not, it may be an indication it can't be done.

Hi I have two application which I have managed to get them to exchange data however, I would like to be able to sort the data out when it is recieved by the other end (server). On the client side, the data is taken from the various forms and sent as below:
String Pname = LblName.Text;
String Pdob = LblDOB.Text;
String PnhsNo = LblNHSno.Text;
String Paddress = RtxtBxAddre.Text;
String PmedicalCon = RtxtBxMedCon.Text;
String pcallOutDetails = RTxtBxCallOut.Text;
byte[] forwardMessage = Encoding.ASCII.GetBytes(Pname + Pdob + PnhsNo + Paddress + PmedicalCon + pcallOutDetails);
sock.Send(forwardMessage);
sock.Shutdown(SocketShutdown.Both);
sock.Close();
On the other end I would now like to take each item and display it in a form, so "Pname" is taken when received and displayed in a text box and then same with the rest of the data. Unlike displaying it in a message box like I have done below:
Socket listener = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
listener.Bind(new IPEndPoint(IPAddress.Any, 2112));
listener.Listen(10);
Socket socket = listener.Accept();
string receivedValue = string.Empty;
byte[] receivedBytes = new byte[1024];
int numBytes = socket.Receive(receivedBytes);
receivedValue = Encoding.ASCII.GetString(receivedBytes,0, numBytes);
MessageBox.Show(receivedValue);
listener.Close();
Help....

You need to put in a delimiter to split the elements at the receiving end. One way to do this would be to use an uncommon character when forming the string, which you can then parse out - don't use a comma just in cast it's present in the input data. I like to use \n in this situation because it's highly unlikely that this will ever be in the input data. Then you simply split the data out at the receiving end using this character sequence.

you can't just concatenate some strings and get away with it, there is no way to separate them again. What if they represent numbers? is 12345 the result of 1 and 2345? or 12 and 345? or...
What you could do is this:
- define a little class that holds the variables (either as strings or, better, as their actual type);
- add [Serializable] attribute;
- make one instance and fill the values from the Form (or whatever your source of information is);
- use XmlSerialize class to turn that object into one XML string;
- transmit that string;
- use XmlSerialize class again to decode the XML string and recreate an instance of your object.
I have an example here[^].

You would be surprised how many people do get away with it thou - running before walking that is, some even just skip both and try to swim - and CP is the bottom of the ocean (help to untie concrete boots - URGENTZ!!!)

I have since tried to put the strings into an arraylist but question now is how do you convert the array list into bytes, cause this doesn't work:
patient.Add(Pname);
patient.Add(Pdob);
patient.Add(PnhsNo);
patient.Add(Paddress);
patient.Add(PmedicalCon);
patient.Add(pcallOutDetails);
byte[] forwardMessage = Encoding.ASCII.GetBytes(patient);
sock.Send(forwardMessage);
sock.Shutdown(SocketShutdown.Both);
sock.Close();
|

A byte[] is just a bad as a string in that if you want to split it at the other end you need to do some work on it prior to creating it (like give it something to be split by)
Really thou, you should follow Luc's advice - he knows what he is talking about

I can't argue with that. Although Pete's approach is fine too under the circumstances (single-line TextBoxes).
