Reading Excel File

B

Brad

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:
"System.Data.OleDb.OleDbException: Could not find installable ISAM.\r\n at

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.

That was exactly my problem! Thanks for saving me the time on google!
