thanks brother but this app. written in C# and

there is fight between me and c# because the general variables

i used to use it in vb6 and continued using it in vb.net

like when i wanna connect to db

i declare a single variable in module then i open it once then i use it in whole project

no one helped me to find this feature in C Sharp

الـ Module غير موجود في C# .

استخدم static class او static members:

class Program
	{
		[STAThread]
		public static void Main()
		{
			Application.EnableVisualStyles();
			Application.SetCompatibleTextRenderingDefault(false);

			try
			{
				Application.Run(new Form1());
			}
			catch (Exception ex)
			{
				MessageBox.Show(ex.ToString());
			}
			finally
			{
				ConnectionManager.Connection.Close();
			}
		}
	}

	public class ConnectionManager
	{
		static readonly string connectionString = Properties.Settings.Default.NorthwindConnectionString;
		static readonly SqlConnection connection;

		static ConnectionManager()
		{
			connection = new SqlConnection(connectionString);
			connection.Open();
		}

		public static SqlConnection Connection
		{
			get
			{
				return connection;
			}
		}
	}

public partial class Form1 : Form
	{
		public Form1()
		{
			InitializeComponent();
		}

		private void Form1_Load(object sender, EventArgs e)
		{
			SqlDataAdapter da = new SqlDataAdapter("Select * from Employees", ConnectionManager.Connection);
			DataTable tbl = new DataTable();
			da.Fill(tbl);

			dataGridView1.DataSource = tbl;
		}
	}
