what error you are getting.The user name you passed to the second form will be displayed where you placed the label.

change to this line.
label1.Text ="Welcome to:("+ strTextBox+")";

Hello friend,

You can do it in many ways, but i suggest you two easy ways, you can manage one global variable to store you user name, and its accessible in all over your application in any number of forms, and second one you already used, like while creating or calling second form pass that user name as constructor parameter of that form, make second constructor in your second form to get name from it and use it to show in you second form top part.


1) Using global variables at application level

2) Pass value in constructor of calling page
   
Hii buddy

after saw your q.s 1st i done it practically and after successfully debug now here for you

On Form1..................

C#
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace form1
{
    public partial class Form1 : Form
    {


        public Form1()
        {
            InitializeComponent();
        }
// this is your public class that contail your user name...
        public class shubh
        {
            public string shubham;
        }

      
 private void btnlogin_Click(object sender, EventArgs e)
        {
            try
            {
                con = new SqlConnection(s);
                con.Open();
                cmd = new SqlCommand("select username,password from login",con);
                dr = cmd.ExecuteReader();
                while (dr.Read())
                {
                   // string username = txtusername.Text;
                    //string password = txtpassword.Text;
                    if (dr["username"].ToString() == username && dr["password"].ToString() == password)
                    {
                        shubh s = new shubh();
                        s.shubham = txtusername.Text;
                        Form2 hmpage = new Form2(s);
                        hmpage.Show();
                        this.Hide();
                    }
                    else
                    {
                        MessageBox.Show("The username or password you entered is incorrect!", "Logon Message!");
                    }
 

                }
                con.Close();
                dr.Close();
            }
            catch (Exception ex)
            {
 
            }
 
        }
    }
}
Now on form2................

C#
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace tarriff_design_page
{
    public partial class Home : Form
    {
        form1.Form1.shubh s;
        public string sa;
        public Home(form1.Form1.shubh s1)
        {
            InitializeComponent();
            s = s1;

        }
 private void Form2_Load(object sender, EventArgs e)
        {
            sa =s.shubham ;
//on which control you want to show the username....
            label1.Text = s.shubham;
           
        }


    }
}


this will definitely run successfully but the main issue with your partial class of form one and form to here just i used form1 for 1st page and form2 for 2nd page so carefully change this nominations as your both forms that can help you to achieve your necessity ........ thanks


Happy to help

Thabks :)
you can pass as parameter while calling second form and create constructor in second form for retrieving the parameter.
Otherwise you can go for event and delegate.you can create a custom event and call the parameter when showing second form. in second form create a delegate to handle it.
