Regarding OLE Excel Sheet File Closing

Hi Experts,

I have developed an OLE Application based Excel sheet in invisible mode,wherein i'm populating the data in cells.but the problem is,

when i'm executing my report if i try to open another excel sheet or already opened excel sheet is there in the system then my excel sheet will also be opened/showned on system.

I don't want my excel sheet to be opened while exceuting.

please let me know is there any procedure/method to handle this problem.

Thanks
