Showing username and userlevel after login.

Mithila Das

I have an access db which have 4 fields 1. id 2. Username 3. Password 4. user level and 2 forms. One is login and other is main. I want to show the username and userlevel in main form in two labels after login. So user can know which is his id and user level. And i want to control some functions enable or disable by userlevel. How can i do it. Please help me.

For quick test, I created a FormParent (and set property IsMdiContainer to true) and created another form called Login.

In this case, I have statusStrip control that holds two labels - one for username and another for userlevel.

I have one method called UpdateStatus on Parent/MDI form that updates these labels.
And later, on login form, once login is successful, you can call the public method to update the statusStrip accordingly.
public partial class FormParent : Form
    {
        public FormParent()
        {
            InitializeComponent();
            var login = new Login();
            login.MdiParent = this;
            login.Show();
        }
        public void UpdateStatus(string username, string userlevel)
        {
            this.toolStripStatusLabel1.Text = $"User: {username} | ";
            this.toolStripStatusLabel2.Text = $"Level: {userlevel}";
            this.statusStrip1.Refresh();
        }
    }
Login form contains the textboxes and button and on button click, it just calls the public method to update if login is successful.
public partial class Login : Form
    {
        public Login()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //some logic to validate credentials
            ((FormParent)this.MdiParent).UpdateStatus(textBox1.Text, "Level 1");
            var someForm = new Form1();
            someForm.MdiParent = this.MdiParent;
            someForm.Show();
            this.Close();
        }
    }
After clicking on Login button,

Hi Mithila,

In your login form declare a variable globally,

public static string UserName = "";

In your login button write the below code,
private void button1_Click(object sender, EventArgs e)
       {
           UserName = txtUserName.Text;
           Form1 f1 = new Form1();
           f1.ShowDialog();
       }
In your main form i am getting this variable value,please find the below code for your reference,
private void Form1_Load(object sender, System.EventArgs e)
       {
           MessageBox.Show(Login.UserName.ToString());
       }
