objBusy = new BusinessLogic();
string strFileName = FileUpload1.PostedFile.FileName;
string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFileName + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection objConn = new OleDbConnection(connectionString);
objConn.Open();
String strConString = "SELECT * FROM [Product1$]";
//where date = CDate('" + DateTime.Today.ToShortDateString() + "')";
OleDbCommand objCmdSelect = new OleDbCommand(strConString, objConn);
// Create new OleDbDataAdapter that is used to build a DataSet
// based on the preceding SQL SELECT statement.
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
// Pass the Select command to the adapter.
objAdapter1.SelectCommand = objCmdSelect;
// Create new DataSet to hold information from the worksheet.
DataSet objDataset1 = new DataSet();
objAdapter1.Fill(objDataset1, "ExcelData");
after this if i looks on the DataSet i see some of the cell value not read from the Excel file, what was the problem and how to resolve this?

If I use Microsoft.Jet.OLEDB.4.0 to retreive for example named range or sheet from Excel and use it as data source for some server control on the ASP page, everything works fine. But when I try to get table from Excel like this: "select * from [Table1]", debugger complains that database engine could not find object Table1. So how should I reference Table1 in Excel file so that the database engine could find it?
string strFileName = FileUpload1.PostedFile.FileName; string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFileName + ";" + "Extended Properties=Excel 8.0;"; OleDbConnection objConn = new OleDbConnection(connectionString); objConn.Open(); String strConString = "SELECT * FROM [Product Classification 5$]"; //where date = CDate('" + DateTime.Today.ToShortDateString() + "')"; OleDbCommand objCmdSelect = new OleDbCommand(strConString, objConn); // Create new OleDbDataAdapter that is used to build a DataSet // based on the preceding SQL SELECT statement. OleDbDataAdapter objAdapter1 = new OleDbDataAdapter(); // Pass the Select command to the adapter. objAdapter1.SelectCommand = objCmdSelect; // Create new DataSet to hold information from the worksheet. DataSet objDataset1 = new DataSet(); objAdapter1.Fill(objDataset1, "ExcelData");
