Hi,
Thanks for your view, if you could give me some suggestion, I'll be very grateful.

I want to use Excel on the web server to create an .xls file and these codes shows how i create the excel app :
// these codes are in c#
Excel.ApplicationClass myExcel = new Excel.ApplicationClass();
myExcel.Visible = false;
Excel.WorkBooks.add(true);
Excel.WorkBook myBook = Excel.WorkBooks[1];
.......
// when work finished, close it.
myBook.close(true, "temp.xls", Missing.value);
myExcel.Quit();
But, after these codes, there's still EXCEL process zombies in the memory.
How to solve the zombie process?
Does anybody could give some suggestion?
