yes sir, I got it sorry for bothering you

Sir, it was successful, whenever I re-runs the form it was not stored. means it was not in the collectons.

I appreciate or your help.
foreach (Form f in Application.OpenForms)

f.controls.contains(treeview1.Nodes["Market"].Nodes.Add(Textbox1.text));

I want to add child node to parent node of treeview from another form.
I tried this code, this is executing but not adding a child node.
I have tree view in form 1. I want to add it from form 2 textbox value in button ckick event. I did like this
form1 frm=new form1();
frm.treeview1.Nodes["Market"].Nodes.Add(textbox1.value);
can u let me know the problem

thanks a lot sir it works

yes sir I got your point so what's the solution for this

Sir I used stream writer only.
{
string FILE_NAME = @"C:\\TSOSM\\" + (newmarketname.Text + ("\\" + (newmarketname.Text + ".txt")));
System.IO.File.Create(FILE_NAME);
int i;
string[] aryText = { "", "", "", "", "", "", "" };
System.IO.StreamWriter objWriter = new System.IO.StreamWriter(FILE_NAME,true);
for (i = 0; (i <= aryText.Length); i++)
{
objWriter.WriteLine(aryText[i]);
}
objWriter.Close();
}

Now you said that proper override. How can I use that override here.

no sharing access are there sir,

{
if (!System.IO.Directory.Exists(("C:\\TSOSM\\" + (newmarketname.Text + ""))))
{
System.IO.Directory.CreateDirectory(("C:\\TSOSM\\" + (newmarketname.Text + "")));
}
{
string FILE_NAME = @"C:\\TSOSM\\" + (newmarketname.Text + ("\\" + (newmarketname.Text + ".txt")));
System.IO.File.Create(FILE_NAME);
int i;
string[] aryText = { "<ticker>", "<date>", "<open>", "<high>", "<low>", "<close>", "<vol>" };
System.IO.StreamWriter objWriter = new System.IO.StreamWriter(FILE_NAME,true);
for (i = 0; (i <= aryText.Length); i++)
{
objWriter.WriteLine(aryText[i]);
}
objWriter.Close();
}
}
I am not getting why is that error, sir there is any problem with the code.

yes sir, now I restarted my pc and run only mu app then also same error

No sir, any text file is not opened. at line of stream writer any error is there, because after that it was not moving to for loop.

Thanks for reply Karthik sir, I appreciate that. but I am getting this error after changing array diclaration
the process cannot be access the file'c:\TSO0SM\abc\abc.txt' because it is using by another process.
process not entering in to for loop.

text file is created but line is not inserted. may be problem in array declaration. I know the way is right but what's the error.

line is not inserting

Thanks for support I got it.

if(HasValidRegistryKeys()) //Check if initial settings are already there
{
Runnable=true;
}
else
{
//Not installed, lets setup app settings
//Assume that the application is running for the first time.
try
{
SetupRegistry(); //Set installation=done
SetupDatabase();
//Setup more things.
Runnable=true;
}
catch()
{Runnable=false;}

}

//Run the app
if(Runnable)
{
RunApp();
