I'm having a problem reading data from an Excel file into a dataset. Can
anybody give me an idea of what's happening? I've included the problematic
source and the error message to the end of this message.
TIA
Brad
Here's a snippet of my source code:
//Retrieve data from the Excel spreadsheet file
string myConnectionString;
OleDbConnection myConnection;
OleDbDataAdapter myAdapter;
DataSet myDataSet = new DataSet("XLS");
myConnectionString = "provider=Microsoft.Jet.OLEDB.4.0;data source=" +
FileName + ";Extended Properties=Excel 8.0;HDR=Yes;IMEX=1";
myConnection = new OleDbConnection(myConnectionString);
myAdapter = new OleDbDataAdapter("select * from [Dataset$]", myConnection);
myAdapter.Fill(myDataSet);
myConnection.Close();
return (myDataSet);
}
Here's the Error Message:

I'd say you want something like this
select * from [Sheet1]
Its the name of the SHEET (bottom left) when you have the excel file open in
the program Microsoft Excel.
Its not the name of the DataSet.
