Hello Experts,

I have what I think is a pretty basic question -- I have modified the attached snippet to fill a spreadsheet from a dataview (via an array).  When the procedure completes the spreadsheet is visible and called "Book1."

I have been trying to modify the code so that I can create an xls with a specficied filename and then save and close the the XLS.

So how can I create an XLS called "c:\\mySpreadsheet.xls"?

Thanks for your help.

The attached snippet (pulled from http://support.microsoft.com/kb/302096/EN-US/)
Excel.Application objApp;

      Excel._Workbook objBook;
 

      private void button1_Click(object sender, System.EventArgs e)

      {

         Excel.Workbooks objBooks;

         Excel.Sheets objSheets;

         Excel._Worksheet objSheet;

         Excel.Range range;
 

         try

         {

            // Instantiate Excel and start a new workbook.

            objApp = new Excel.Application();

            objBooks = objApp.Workbooks;

            objBook = objBooks.Add( Missing.Value );

            objSheets = objBook.Worksheets;

            objSheet = (Excel._Worksheet)objSheets.get_Item(1);
 

            //Get the range where the starting cell has the address

            //m_sStartingCell and its dimensions are m_iNumRows x m_iNumCols.

            range = objSheet.get_Range("A1", Missing.Value);

            range = range.get_Resize(5, 5);
 

            if (this.FillWithStrings.Checked == false)

            {

               //Create an array.

               double[,] saRet = new double[5, 5];
 

               //Fill the array.

               for (long iRow = 0; iRow < 5; iRow++)

               {

                  for (long iCol = 0; iCol < 5; iCol++)

                  {

                     //Put a counter in the cell.

                     saRet[iRow, iCol] = iRow * iCol;

                  }

               }
 

               //Set the range value to the array.

               range.set_Value(Missing.Value, saRet );

            }
 

            else

            {

               //Create an array.

               string[,] saRet = new string[5, 5];
 

               //Fill the array.

               for (long iRow = 0; iRow < 5; iRow++)

               {

                  for (long iCol = 0; iCol < 5; iCol++)

                  {

                     //Put the row and column address in the cell.

                     saRet[iRow, iCol] = iRow.ToString() + "|" + iCol.ToString();

                  }

               }
 

               //Set the range value to the array.

               range.set_Value(Missing.Value, saRet );

            }
 

            //Return control of Excel to the user.

            objApp.Visible = true;

            objApp.UserControl = true;

         }

         catch( Exception theException ) 

         {

            String errorMessage;

            errorMessage = "Error: ";

            errorMessage = String.Concat( errorMessage, theException.Message );

            errorMessage = String.Concat( errorMessage, " Line: " );

            errorMessage = String.Concat( errorMessage, theException.Source );
 

            MessageBox.Show( errorMessage, "Error" );

         }

      }

I got SaveAs to work, but I found using the below line was better for my purposes.  Where oName is the FileName that I assigned.

 objBook.Close(true, oName, oMissing);

Thanks.
