 Hey, thanks for the response.
But I have tested the recursive function, it depth is max. 10 in all cases and I pass 2 integers each time. And important of all, it is running OK when I shut down all nonrecursive heavy routines running before it.
Somehow, there are pending methods left, raising the program proximity to the stack limit. Anyway, do you know how can I raise the stack limit ? Is it possible ?

Hello and merry christmas

Can you help me ?
My best wishes.

I haven't tested this or anything, but I'm pretty sure all you need to do is use the ToString() method. For instance...
DateTime time = DateTime.Now;
string formattedTime = time.ToString("MM/dd/yyyy hh:mm:ss");
For more information, check out MSDN's custom DateTime format strings[^].

Hi,
Is there anyway I can set a timeout for an asynchronous call in remoting. The intention is that if the method takes a long time and it is not worth waiting that long, the execution should proceed. Kind of taking off the blocking aspect of EndInvoke call.

What was wrong with the answer[^] that I gave to you a few days ago? If you didn't understand it then I am more than happy to clarify anything. I did make some assumptions that you knew your way around the SqlConnection and SqlCommand objects well enough to perform a normal query (SELECT, INSERT, DELETE, UPDATE) so maybe that was incorrect.
Do you want to know more?

Use your fmapppas() constructor to call login form. And try to execute your login related logic.That will be a good solution for this.

The problem is that the ApplicationContext MainForm of your application is the fmapppas form. That is because you are starting the applicatoin in this form with the code: Application.Run(new fmapppas());
When this form closes, u are exiting the application.
On the other hand, if u hide the fmapppas form, the application will keep on running forever because the user can't close the hidden form and thus finalize the application because there is no GUI available (would have to do it through the taskmanager).
Solutions: You should always use the application's main form as the ApplicationContext mainform: That is, start the app with the mainfm or set it as the ApplicationContext's MainForm if your using a custom application context:
[STAThread]
public static void Main()
{
Application.Run(new mainform())
}
then override the main forms OnLoad method and start the logging form from there:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
fmapppas frm=new frmappas;
frm.ShowDialog(this);
}
If u really dont want to change the structure u have right now, u could probably fix your problem simply overriding the mainfm's OnClosed method and force the hidden form to close also:
protected override OnClosed(EventArgs e)
{
fmapppas.Close();
base.OnClosed(e);
}

i using this method to solve this problem
At first build a "Module" in the Solution
like this:
//===============
start.cs
//===============
using System;
using System.Windows.Forms;
namespace test
{
public class Start
{
public static string dbstr;
[STAThread]
static void Main()
{
FrmLogin frm = new FrmLogin();
if(frm.ShowDialog()==DialogResult.OK)
{
Application.Run(new FrmMain());
}
}
}
}
And build a Login Form to return a value to this module
//=================================
FrmLogin.cs
//=================================
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Diagnostics;
using System.Data.OleDb;
namespace test
{
///
/// FrmLogin
///
public class FrmLogin : System.Windows.Forms.Form
{
private System.Windows.Forms.Button login;
private System.Windows.Forms.TextBox uname;
private System.Windows.Forms.TextBox pwd;
private System.Data.OleDb.OleDbDataAdapter user;
private System.Data.OleDb.OleDbConnection conn;
private System.Data.OleDb.OleDbCommand oleDbSelectCommand1;
private System.Data.OleDb.OleDbCommand oleDbInsertCommand1;
private System.Data.OleDb.OleDbCommand oleDbUpdateCommand1;
private System.Data.OleDb.OleDbCommand oleDbDeleteCommand1;
private test.DSuser dSuser1;
private System.Windows.Forms.Button cancel;
///
///
///
private System.ComponentModel.Container components = null;
public FrmLogin()
{
//
//
//
InitializeComponent();
//
//this.conn.ConnectionString=Start.dbstr;
//
// TODO: 在 InitializeComponent //
}
///
///
///
protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}
private void login_Click(object sender, System.EventArgs e)
{
try
{
this.user.SelectCommand.Parameters["username"].Value=this.uname.Text.Trim();
this.user.SelectCommand.Parameters["password"].Value=this.pwd.Text.Trim();
this.dSuser1.Clear();
this.user.Fill(this.dSuser1);
if(this.dSuser1.user.Rows.Count>0)
{
this.DialogResult=DialogResult.OK;
}
else
{
MessageBox.Show("Bad User Name Or Password!");
this.uname.ResetText();
this.pwd.ResetText();
return;
}
}
catch(Exception ex)
{
Debug.Write(ex);
}
finally
{}
}
private void cancel_Click(object sender, System.EventArgs e)
{
this.DialogResult=DialogResult.Cancel;
}
}
}
When user input the right UN and PWD the Module will open the MainForm.
hope it will some help for you.
my english is poor
hehe

Your xml file will be like this.
<configuration><br />
<appSettings><br />
<add key="ConnString" value="Your Connection String" /><br />
</appSettings><br />
</configuration></code><br />
<br />
<br />
You can use the above connection string value in your C# class provided you need to refer <code>System.Configuration in your class file.
using System.Configuration.Once you refer this namespace, then you can use below mentioned code to get the connection string into a string variable.
string ConnString=ConfigurationSettings.AppSettings["ConnString"];

Hi
Well this is my first posting at CodeProject and in the past one month or so i had been actively using the codeproject site, it's vast expanse of knowledge base, code snippets and even full source code helps and samples has really impressed me a lot. Now i hope to remain an active member by submitting articles, posting and replying on quries.
here's my first query to the group
In a Web Browser control that i am using (C#.NET Windows app) i want to clear the history of pages that have been browsed, this being done at runtime may be at the hit of a button or after certain no. of pages have been browsed.
Any ideas there.

The wonders of blank sa passwords 
You say your SQL Server is windows authentication and then you supply a user (sa), which is a SQL User. Try removing it and ensuring that the application is running as a domain user.
This is not a C# question, please post in the appropriate forum.

Hi,
thanks for your reply. please make me clear. without providing user name and passport, the error occured then only trying this option. if posssible send an sample.
strConnectionString = "Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=atc;Data Source=" + m_strServer + ";";
you can make direct reply to murali_utr@vsnl.net also.
Have A Nice Day!

I believe you are missing "Trusted_Connection=true;", but even with this addition,
your connection string will only work if you are logged in as a member of the NT domain the server is running on (or a trusted domain) and that user or group has been granted access to the requested database.

Hi all,
I am design a three layer system in C# (view layer, business object layer
and data layer). But when I look into the J2EE infrastructure, the object
bean(business object) incorporates the SQL data function into the object itself. It seems violates the layer design principles coz it mixes the data layer with the business object layer. But in the other hand, it seems a more OO design coz the business object integrates all those related information into the business object, so when there is a later change in the business object specificiation, the developer needs to change only the business object instead of changing the object and the data layer.
So what approach should I choose ?
Thanks
