Absolutely perfect! Well, I can throw away the code I had because this is exactly what I need. Although, I’m glad I struggled my way to get to this point as I picked up some really great experience along the way.
Anyways, thanks for your help. I owe you one!

Hi all,
I need some help to create technical indicator for the project. I have to read the file in csv and create same file after reading and calculating the values and some more with indicator and model. I need some little help for creating technical inidcator like SoctchRSI, RSI, EMA, MACD.
Thanks in advance.

I can't make heads or tails out of your question, but I reckon the easiest way to read a CSV is to read a line at a time, then to do a split on the ,. If you can break your request into plain English, I'd be happy to try and help some more.

Ok, I have an application that is sitting on a server and listning for requests using a Socket and on port 8221. Well this servers app's sole purpose is to take in what the user wants and run a query based on that incoming requests and parameters.
Ok, application seems to be working fine functionally except for a few issues that I am not having any luck trying to fingure out what to do:
1. I fixed memory leaks, the memory seems to be fairly constant between 6 and 25K. But the problem is that the handle count seems to be going up. For example I am looking at the taskman on the server, the mem is at 7568 and the handles are up to 2800+. How or any suggestions on reclaming these handles back or this is a non issue.
2. Second, since this is a communication app it is sitting on the server minding it's own business and all of a sudden sometimes i see it takes up 99% of the cpu WHILE IT HAS NO PENDING CONNECTIONS.
Any suggestions as to how I can address these issues.
BTW this is one of the best .net blogs i have ever read

So, my thanks to this guy for learning and helping me track down my memory leaks.

Suppress the redraw event on what? Some things need to be drawn for feedback purposes.

When press Ctrl+v in richtextbox, how to get the text which is pasted,
how can i do?
|
|
|
|
|

hii,
you can do so by using keyup event if the keys pressed were contol+v get the data in clibbord here is simple example
private void richTextBox1_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e)
{
String PasteText="";
if(e.KeyData==(Keys.Control|Keys.V))
{
PasteText=(String)Clipboard.GetDataObject().GetData(typeof(String));
if(PasteText!=null)
MessageBox.Show(Clipboard.GetDataObject().GetData(typeof(String)).ToString());
}
}
|
|
|
|
|
there's a much easier way.
richTextBox1.Undo();

HI
My problem is that I am reading a image field from the database table .
then I need to Convert that image field value into a byte[] .
dread = sqlcomm.ExecuteReader();
sqlcomm = new SqlCommand("getCont1" ,sqlconn);
sqlcomm.CommandType = CommandType.StoredProcedure;
dread = sqlcomm.ExecuteReader();
while ( dread.Read())
{ temp= (dread.GetValue(0));
}
this "temp" var store the image field value as object .
now i need to convert this object into byte[] as i have to pass it to a function which take byte[] as parameter.
what I need to do ?
thanks
ss
thanks

An image SQL server column type translates to a byte array (byte[])framework type. In your example, the 'temp' variable would have to be declared as byte[].
You could also use the GetBytes(int index) method on your reader.
For a more complete type mapping table, look here[^].
The most exciting phrase to hear in science, the one that heralds the most discoveries, is not 'Eureka!' ('I found it!') but 'That's funny...’

if you want to convert it to byte array you have to serialize it.
using System.Runtime.Serialization.Formatters.Binary;
/*Note i suppose your object is serializable if not add [Serializable] attrubite to your object class*/
BinaryFormatter Serialize=new BinaryFormatter();
MemoryStream stream=new MemoryStream();
byte[]ObjectInBytes=Serialize.Serialize(stream,temp);
//to Deserialize
stream=new MemoryStream(ObjectInBytes);
stream.Seek(0,SeekOrigin.Begin);
temp=(TypeOfYourObject) Serialize.Deserialize(stream);

Hi there, im working on a little client / server application, and im having trouble sending messages between the two. I can send messages no problem as text, but when I serialize an xml class and send that it gives me an error "There is an error in XML document (6, 16)".
Heres the code:
MessageClass - this is what is being serialized and submitted
//--------------------------------------------
//--------------------------------------------
public class messageClass
{
public int clientID;
public int messageType;
public int data;
public messageClass()
{
}
}
//--------------------------------------------
//--------------------------------------------
SERVER code - this is where the class is declared, filled in and submitted. NOTE: I want "data" to be an object, but ive used int here for debugging.
//--------------------------------------------
//--------------------------------------------
Socket listener = (Socket)ar.AsyncState;
client = listener.EndAccept(ar);
Console.WriteLine("client {0}, joined", client.RemoteEndPoint);
// send the user a session ID
string strSessionID = sessionID.ToString();
sessionID++;
//Byte[] byteSessionID = System.Text.Encoding.ASCII.GetBytes(strSessionID.ToCharArray());
//client.Send(byteSessionID, byteSessionID.Length, 0);
messageClass message = new messageClass();
message.clientID = sessionID;
message.messageType = 1;
message.data = 1;
XmlSerializer xml = new XmlSerializer(message.GetType());
MemoryStream transmitStream = new MemoryStream();
xml.Serialize(transmitStream, message);
client.Send(transmitStream.GetBuffer());
Console.WriteLine("Sent message");
listener.BeginAccept(new AsyncCallback(OnConnectRequest), listener);
//--------------------------------------------
//--------------------------------------------
CLIENT - recieving and decoding message, this is where the error is occuring. Message is recieved but will not parse:
//--------------------------------------------
//--------------------------------------------
public void setupRecieveCallback(Socket sock)
{
try
{
AsyncCallback recieveData = new AsyncCallback(OnRecievedData);
sock.BeginReceive(byteBuffer, 0, byteBuffer.Length, SocketFlags.None, recieveData, sock);
}
catch(Exception ex)
{
MessageBox.Show(this, ex.Message, "Setup Recieve callback failed!");
}
}
public void OnRecievedData(IAsyncResult ar)
{
// Socket was the passed in objct
Socket sock = (Socket)ar.AsyncState;
// check if we got any data
try
{
int bytesRecieved = sock.EndReceive(ar);
if (bytesRecieved > 0)
{
// write the data to the list
//String recieved = Encoding.ASCII.GetString(byteBuffer, 0, bytesRecieved);
//##########################
// DO SOMETHING WITH MESSAGE
//##########################
// decode it back to a message class
messageClass myMessage = new messageClass();
XmlSerializer xml = new XmlSerializer(myMessage.GetType());
MemoryStream messageStream = new MemoryStream(byteBuffer);
myMessage = (messageClass)xml.Deserialize(messageStream);
//byte[] buffer = new byte[2048];
//messageStream.Read(buffer, 0, 2048);
int data = myMessage.data;
MessageBox.Show(data.ToString(), "Message");
//MessageBox.Show(recieved, "Message");
// if still connected, reastablish callback
setupRecieveCallback(sock);
}
else
{
// if no data was recieved then the connection is probably dead
Console.WriteLine("client {0}, disconnected", sock.RemoteEndPoint);
sock.Shutdown(SocketShutdown.Both);
sock.Close();
}
}
catch (Exception ex)
{
MessageBox.Show(this, ex.Message, "Unusual error during recieve!");
}
}
//--------------------------------------------
//--------------------------------------------
Just for cicks here is the actual message that is recieved, pefore trying to parse:
//--------------------------------------------
//--------------------------------------------
<messageclass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<clientid>2
<messagetype>1
1
//--------------------------------------------
//--------------------------------------------
Any help much appreciated...

Sorry, forgot to tell it not to treat barckets as HTML. Here is the actual XML that is recieved by the client:
<?xml version="1.0" encoding="utf-8"?>
<messageClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<clientID>2</clientID>
<messageType>1</messageType>
<data>1</data>
</messageClass>
