Implementing Progress Bar in FileStream

Question

I have a code that downloads the file from SQL Server Database, and save it into the target location : 

            SqlConnection conn = new SqlConnection(string.Format("server=xslogic-pc; uid=sa; pwd=hotmail; database=files"));

            SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM Files WHERE(status IS NULL) order by id", conn);

            adapter.Fill(dataSet1.Tables[0]);

            string tempDir = Path.GetTempPath();

            if (dataSet1 != null && dataSet1.Tables.Count > 0 && dataSet1.Tables[0].Rows.Count > 0)

            {

                DataRow row = dataSet1.Tables[0].Rows[0];  // If you go sorting the columns, you may need to change this

                fileid = row["id"].ToString();

                Class1.InsertValue("update files set status = '1' where id = '" + fileid + "'");

                filename = (string)row["OriginalName"];

                lbldownload.Text = "Downloading file : " + filename;

                LaunchedFile = tempDir + filename;                             // Get our new Filename and path

                FileInfo fi = new FileInfo(LaunchedFile);                      // Get our hands around the file specification   

                FileStream fs = fi.Create();                                   // Create the new file

                byte[] Data = new byte[0];                                     // Instantiate a buffer to hold the data   

                Data = (byte[])row["FileData"];                                // Load the buffer

                int ArraySize = new int();                                     // Find the Size of the buffer (aka file)

                ArraySize = Data.GetUpperBound(0);

                fs.Write(Data, 0, ArraySize);                                  // Write the file to disk. If a really large file, then braek it up

                fs.Flush();                                                    // Flush the bytes to the disk   

                fs.Close();                                                    // Close the file.

                File.Move(LaunchedFile, @"D:\\Zeeshan\\Transmission\\to\\" + filename);

                Class1.InsertValue("update files set status = '2' where id = '" + fileid + "'");

                lbldownload.Text = "Downloading file : " + filename + "  -  COMPLETED";

                fileid = "";

                filename = "";

                adapter.Dispose();

                dataSet1.Clear();

my above given code works perfectly, i just want to implement a  progress bar in my application so that i can have a look that how much file downloading is left....

can anyone help me out with this...
