It is possible but might be a little bit complicated. Does your application opens the Excel file or Excel file was opened through Excel or another application already?
In the first senario, once the excel is opened, start reading the data, do not close the report file (dispose the report) or close the excel file
In the second senario, it is a little bit more complicated. You need to use low level Excel ActiveX functions. The procedure is:
1. Open reference to Excel
2. Activate the desired workbook if it is already opened
or open a new file
3. Activate the sheet containing the data
4. Read the data
5. Loop if necessary (step 2 if diff wb, step 3 if diff sht, 4 if same sheet)
6. Close Excel reference (Very important, close the
ref only, do not use Application.Exit to exit Excel).
Hope this helps,
