Potential problems:
1. Excel exit is a problem when Office2000 is used. Excel may not be accurately exited, or an error may occur when Excel is exited. This may leave a lot of Excel processes in the system. In practice, it is found that when office2003 is used, this problem is solved. Officexp and office2002 have not been tested and do not know if they have been solved.
2. Data operations are slow. This is related to the COM interface. If you have a deep understanding of COM, you can perform many optimizations to greatly improve the efficiency.
Temporary solution:
1. Use excel2003 to exit Excel
2. Using the spreadsheet component of Office Web Components V10/V11 is currently a good solution.
