do a string.Split and pass that Ctrl char (the square i see) ~~and~~ as the delimiter.

Here you go :

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < message.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}

Hope this helps.
by the way, I too used all this in my early carrier. Wink | ;)

if i am able to do it like this
100=ARCA10=169|0|
using substring
now i have to get value of first tag
eg
100=
Result should be "ARCA"
i want it in seperate string

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < message.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}<br />
string firstTagString = fixTable["100"].ToString()

This will give you string which is there in tag 100, no matter at what position it is at.
I am telling you this because FIX is a tag based protocol and not a position based. The position may vary from message to message.
It is a more generalized solution for your scenario.

you mean fixString.Length here

My Mistake OMG | :OMG:

It should be fixArray
Here's your code

String fixString = "Whateever";<br />
string[] fixArray = fixString.Split(Convert.ToChar(1)); <br />
//I used 1 because FIX message uses this as delimiter...<br />
HashTable fixTable = new HashTable();<br />
string[] fieldArray = null;<br />
for (int fieldCount = 1; fieldCount < fixArray.Length; fieldCount++)<br />
{<br />
fieldArray = fixArray[fieldCount].Split('=');<br />
fixTable.Add(fieldArray[0].ToString(), fieldArray[1].ToString()); <br />
}<br />
string firstTagString = fixTable["100"].ToString()

I am new in Oracle and now I'm am struggling to insert into the Oracle Database. The DB connection is fine. I keep getting the error "ORA-01036:illegal variable name/number". Would anyone please tell me what is wrong with the following code (C#):

// Insert user into Tester Table
public void InsertIntoTester(string fname,string lname,string usrname,string passwd,string address, string email, string tester_id)
{
Connection.Open();
string strSQL;
string insertValue= "'"+fname+"',"+"'"+lname+"',"+"'"+usrname+"',"+"'"+passwd+"',"+"'"+address+"',"+"'"+email+"',"+"'"+tester_id+"'";

strSQL = " INSERT INTO TESTER (FIRSTNAME, LASTNAME, USRNAME, PASSWD, ADDRESS, EMAIL, TESTERID) VALUES ("+insertValue+")";

//Initializing the command
InsertCommand.CommandType = System.Data.CommandType.Text;
InsertCommand.CommandText = strSQL;

//Clearing the parameters
InsertCommand.Parameters.Clear();

InsertCommand.Parameters.Add(":FIRSTNAME",System.Data.OracleClient.OracleType.VarChar,255);

You are injecting the values in to the SQL command and they you are passing the same data in as parameters. Please stick with the parameters and alter your SQL String so that you are actually using the parameters that you set up.

This injects the values into the SQL. This is the source of a SQL Injection Attack, so you don't want to be injecting values.

What you want to do is alter the SQL String you've set up so that it doesn't inject values into the string.

So... Change insertValues to be a string that contains the parameter names rather than injecting the actual values. So it reads something like this:

string insertValue= ":FIRSTNAME, :LASTNAME, :USRNAME, :PASSWD, :ADDRESS, "+
                    ":EMAIL, :TESTERID";

Passing Objects to threads..

How do I pass objects to threads? VS2005 let me say, t.start((object)obj); but VS2003 (1.1) doesnt. Why? How do I do that in .net 1.1?

Press: 1500 to 2,200 messages in just 6 days? How's that possible sir?

In a multithreaded environment you can have mulitple things happening at the same time, especially in a multicore or multiprocessor environment.

So, how does your solution work if you want to start several threads at the same time?

Re: Passing Objects to threads..

Manas Bhardwaj8-Jun-07 1:03

In .Net 1.1 the ThreadStart never takes a parameter, so you the method which is called on a new thread will have to access the object stored some where else. But keep in mind to make thread safe.
Though this is now possible in 2.0 using Annonymous Methods.
Hope, it is clear now

If threads need different parameters we can name each thread (or group of) and use static hash table (dictionary) to store the parameters.

P.S. I think it is good way to solve this. But I have never worked with FW 1.1. May be it has a different recommended solution

Re: Passing Objects to threads..

you could do this:

create a class that will execute on the thread.

public class ThreadObj
{
private int t1;
private string t2;

public int T1
{
get
{
return t1;
}
set
{
t1 = value;
}
}

public string T2
{
get
{
return t2;
}
set
{
t2 = value;
}
}

public void MyThreadMethod()
{
string t = t2;
}
}

then call this with :

ThreadObj o = new ThreadObj();
o.T2 = "Hello";
o.T1 = 1;

System.Threading.ThreadStart ts = new System.Threading.ThreadStart(o.MyThreadMethod);

System.Threading.Thread tr = new System.Threading.Thread(ts);
tr.Start();

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
