or, you could use this.... ================================================== private void btnLogin_Click(object sender, EventArgs e) { string connectionString = "whatever"; string sql = "SELECT COUNT(*) FROM Users WHERE Name = @Name AND Password = @Password"; using (SqlConnection cn = new SqlConnection(connectionString)) { using (SqlCommand cmd = new SqlCommand(sql, cn)) { cmd.Parameters.AddWithValue("@Name", txtUserName.Text); cmd.Parameters.AddWithValue("@Password", txtPassword.Text); cn.Open(); int count = (int)cmd.ExecuteScalar(); if (count > 0) MessageBox.Show("Login Successful", "Successful", MessageBoxButtons.OK, MessageBoxIcon.Information); else MessageBox.Show("Login Failed. Try Again.", "Failed", MessageBoxButtons.OK, MessageBoxIcon.Error); } } } ============================================================
