Hi, I can import a Excel sheet to an DataSet with an OleDb connection.
For example with this code:

string connstr ="Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:\aaa.xls;Extended Properties=Excel 8.0"/&gt;
       OleDbConnection conn = new OleDbConnection(connstr);
       string strSQL = "SELECT * FROM [Sheet$]";

       OleDbCommand cmd = new OleDbCommand(strSQL, conn);
       DataSet ds = new DataSet();
       OleDbDataAdapter da = new OleDbDataAdapter(cmd);
       da.Fill(ds);

But when I try to import from a sheet in VSTO Workbook the workbook is already open and so I get an error.
Does anyone has an Example how I can import to a Dataset from a VSTO Workbook.
(The sheet that I want to export to a DataSet a member of the VSTO workbook)

Thanks
Chris

Hi,

now I don't get an error, but nothing is in the dataset. Here's my code:

string strWorkbookName = Globals.ThisWorkbook.FullName;
            string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + strWorkbookName + ";Extended Properties='Excel 12.0;HDR=Yes'";
            OleDbConnection xlConn = new OleDbConnection(strConn);
            string strExcelSheet = Globals.Tabelle1.Name;
            Properties='Excel 8.0;HDR=Yes;IMEX=1'";
            OleDbDataAdapter xlDA = new OleDbDataAdapter("Select * from [" + strExcelSheet + "$] ", xlConn);
            xlDA.Fill(dsDataLoad, "dtDLD");
            MessageBox.Show(dtDLD.Rows[7]["colSAPCode"].ToString());
            dataGridView1.DataSource = dtDLD;

Anyone knows what's wrong here
Thanks Chris
