Object reference not set to an instance of an object.

that is probably because sSQL is null. you can check that by putting a break point on that line and see in the watch if it is indeed null. but I don't see that line in the code you posted

okay i will check the sSql

yes it does return null,

what esle can i do

well, I don't know what you were trying to do. post your code and maybe I can understand that.

I can think of 2 cases:
1) you forgot to initializae it
2) you are using another string and made a confusion with it.

it is case 2,

but that reurns null


public class WebForm2 : System.Web.UI.Page

            protected System.Web.UI.WebControls.Button Button1;
            SqlConnection con = new SqlConnection("server=10.217.1.85;User ID=sa;password=oarsjove;Database=ADC11");
            string  strg;
            private void Page_Load(object sender, System.EventArgs e)
            {
                  // Put user code to initialize the page here
            }

            

            private string parseStr(string sSQL)
            {
                  return sSQL.Insert(0, "\\\\ukwatdb20\\wwwroot$\\AutoDataCapture\\Files1\\" );
                  //return sSQL.Insert(0, "c:\\code\\" );
            }
            private string parseSQL (string sSQL)
            {
                  return sSQL.Replace("'", "''");
            }
            private string parse_SQL (string sSQL)
            {
                  return sSQL.Replace("-", "");
            }
            private string parse_hash (string sSQL)
            {
                  return sSQL.Replace("#", ".");
            }

                  //

            {
                  con.Close();
                  con.Open();
                  //                  conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + HttpContext.Current.Server.MapPath("\\AutoDataCapture_2\\Files\\") + Path.GetFileName(postedFile.FileName) +";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"");                              
                           
                  string strr ="SELECT * INTO ADC11.dbo.test1 FROM OPENROWSET('MSDASQL','Driver={Microsoft Excel Driver (*.xls)};DBQ=";
                  strr += parseStr(strg);
                  strr += "','SELECT * FROM [Sheet1$]')";
                  SqlCommand SqlCmd= new SqlCommand(strr,con);
                  SqlCmd.ExecuteNonQuery();
                  //Importing the generic Excel file in to Master SQL Database
                  con.Close();
            }
      }
}

from the code you have given the parseSQL method is not being called. so there is no way you can get an error on that line

     private string parseStr(string sSQL)
            {
                  return sSQL.Insert(0, "\\\\ukwatdb20\\wwwroot$\\AutoDataCapture\\Files1\\" );
                  //return sSQL.Insert(0, "c:\\code\\" );
            }

returns null

I have to create abrowse  button

instead of
return sSQL.Insert(0, "\\\\ukwatdb20\\wwwroot$\\AutoDataCapture\\Files1\\" );
use
return "\\\\ukwatdb20\\wwwroot$\\AutoDataCapture\\Files1\\"+sSQL;

will try this

actually cily

I only gave you a subset of the code not the full version.

the actual problem is that this path

string strr ="SELECT * INTO ADC11.dbo.test1 FROM OPENROWSET('MSDASQL','Driver={Microsoft Excel Driver (*.xls)};DBQ=";
does not let us save any excel file with any format

but this code below allows so to save with any format b\c it has the
Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"");      
incorporated in it
            
      

conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + HttpContext.Current.Server.MapPath("\\AutoDataCapture_2\\Files\\") + Path.GetFileName(postedFile.FileName) +";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"");      

                                      
                  

yeah
