Instead of the clsMaster class write a class for a stream writer. You already have at least one stream writer in your code so i'm assuming you know how this works already, so what exaclty is the issue? If you need help with Stream Writer code check out the msdn page on it or check out the tutorial section where xav has some nice examples. I was getting build errors when I compiled so I can't really give you any further help until I get it debuged, wich isn't on the top of my priority list.

thanks for u'r reply but i have already created a class for text writer but it didn't works at all...i am working with remote desktop as my server and i need to create a text file in that server and now i am using database for storing the datas but now i need to directly store it in a text file ..can u give me u'r suggetion..

remote desktop? This shouldn't change the process. If you are connecting to the server ok this shoudn't matter. The process for writing a text file is much simpler than that of writing the data in a db file and shouldn't be the problem. Are you sure you did everything the same as far as passing data to the writer class instead of the sql class? Can I see the class for the stream writer? Maybe I could see what went wrong from that. Or if you figure it out let me know what the holdup was. Im currious as to why a writer would give you problems when the sql solution was working already.

ya i have given every thing but text file is not created ...do u have any ideas ...the code which i have written for text writer is as follows

using System;
using System.IO;
using System.Collections;

public class Program
{
public Program ()
{
Hashtable ht = new Hashtable();
ArrayList arr = new ArrayList();
string[] lines = File.ReadAllLines(@"d:\\test.txt");
string temp = null;

for (int i = 0; i < lines.Length; i++)
{
temp = lines[i].Substring(0, lines[i].IndexOf(','));
if (temp.ToUpper().StartsWith("BTS_ID")) continue;
if (i == 1 || arr.IndexOf(temp) == -1)
{
arr.Add(temp);
}
}

string[] pars = null;
string bts = null;
for (int i = 0; i < lines.Length; i++)
{
lines[i] = lines[i].TrimEnd();
if (lines[i] == "")
{
if (i == lines.Length - 1)
{
ht.Add(bts, pars);
}
else
{
continue;
}
}
if (lines[i].ToUpper().StartsWith("BTS_ID"))
{
if (i > 0)
{
ht.Add(bts, pars);
}
bts = lines[i].Substring(7).TrimEnd(',');
pars = new string[arr.Count];
for (int k = 0; k < arr.Count; k++)
{
pars[k] = "null";
}
}
else
{
for (int j = 0; j < arr.Count; j++)
{
if (lines[i].ToUpper().StartsWith((string)arr[j]))
{
pars[j] = (lines[i].TrimEnd().Split(','))[1];
}
}
if (i == lines.Length - 1) ht.Add(bts, pars);
}
}

// display header line

TextWriter tw = Console.Out;

using (StreamWriter sw = new StreamWriter(@":\\test.txt")) // or whatever
{
// set output to file

Console.SetOut(sw);

// write header line

Console.Write("BTS_ID ");

foreach (string title in arr)
{
Console.Write(title);
Console.Write(" ");
}

Console.WriteLine();

// write hash table
foreach (string key in ht.Keys)
{
Console.Write("{0} ", key);
pars = (string[])ht[key];
foreach (string par in pars)
{
Console.Write(par);
Console.Write(" ");
}
Console.WriteLine();
}
}

// restore console output

Console.SetOut(tw);
Console.ReadKey();
}
}

plz do reply for my post

[gaylo565]

There are a couple of problems with the code you posted. First thing I noticed was your code to reset the console output to standard wont work. I think it takes a couple more lines than that: Console.SetOut Method Try this link for a good example of a stream writer like the one you want (it even has a stream reader built in). You also need to use the "new" opperator for instantiating an array. You can still do it together with its declaration but you need the "new" keyword. Thats all I saw so far...Good Luck and I hope this helped

... and next time, use CODE tags. ;) And +rep to gaylo.

[gaylo565]

thx xav:) Im sure it will come back around once i spread enough around to give you more.
