It's not to difficult: but exactly how you do this depends on how you handle the login on the first place.

Personally, I would bring the main form up first, and open the login form in the Load event:

frmLogin log = new frmLogin();
if (log.ShowDialog() != DialogResult.OK)
   {
   Close();
   }

You then do all the validation in the login form and exit with OK or Cancel depending on if the logon works or not - if it doesn't, then the code above closes the application.

All you then have to do is add a property to the login form which returns the login user name, and access it in the main firm code:

Text = "User : " + log.UserName;

can you show us your code snippets?
OriginalGriff was right,using property to the log in form ur If you want create a class for property that will hold the value you want to pass

C#

Public Class MyClass
{
public string myValue{get;set;}

}

Log in form:

C#

If (textBox1.text==password and textBox2.Text==UserAccount)
{
  var cls=new myClass;//instantiate the class
  cls.myValue=textBox2.Text;//pass the value
  MainForm.ShowDialog();
}

then in Main form

C#

var cls=new myClass;
textBox3.Text=cls.myValue;

Hi there. when you are deciding for creating a application consider followings:
1-what data you need?
2-create a class that has your requested data:
In a class you can define property for working with that class such as this:

C#

class Person
{
    public string UserName { get; set; }
    public string Password { get; set; }

    private Person()
    {
        Validate();
    }
    public Person()
    {

    }

    private void Validate()
    {
        //Here you must connect to some dataSource such as SQL server for correction of entry data
    }
}

3-now you must design your UI(form).
4- I suppose you create a form that has two TextBoxes and two Button. In LogButton_Click:

C#

public Form1()
{
    InitializeComponent();
}

private void LogInButton_Click(object sender, EventArgs e)
{
    Person person = new Person();
    person.UserName = UsernameTextBox.Text;
    person.Password = PasswordTextBox.Text;
}

Thanks alot griff but,
I dont know what to fill in where or what to keep as it is
like .. what becomes log or frmlogin or log.username

I used textboxes to enter the username and password there only a password check who checks if the value is equal with the right password so the username is just for fun
