Answer 1

So you have a form with ComboBox filled with account names, a TextBox for password input, and a Button for opening the new form.

Set the TextBox's property PasswordChar to desired mask character:

textBox1.PasswordChar = '*';

Create a new click method for your login-button by double clicking it in the designer. It should create a new handler:

private void loginButton_Click(object sender, EventArgs e)
{
   // Check if the user haven't chosen an account
   if (comboBox1.Text == "") { return; }

   // Check if the password TextBox is empty
   if (textBox1.Text == "") { return; }

   // Create a new method for checking the account and password, which returns a bool
   bool loginSuccess = CheckUserInput(comboBox1.Text.Trim(), textBox1.Text);

   if (loginSuccess)
   {
      // Create a new instance of your user-interface form. Give the account name and password
      // to it's constructor
      UserForm newForm = new UserForm(comboBox1.Text.Trim(), textBox1.Text.Trim()))

      // Show the created UserForm form
      newForm.Show();

      // Close this login form
      this.Close();
   }
}

Edit your UserForm form constructor to take 2 string parameters:

public UserForm(string accountName, string accountPassword)
{
   InitializeComponent();

   // ...
}

Adding the 2 string parameters is optional. Hope this answered your question.

Example of "CheckUserInput":

private bool CheckUserInput(string account, string password)
{
   // your conditions...
   return true;
}
