我应该使用 auto_open/close 还是 workbook_open/beforeclose 在打开时运行 VBA？

Question

In Excel 2003/2007, in which cases should I use auto_open/auto_close routines, and in which cases should I use the workbook_open/workbook_beforeclose events instead?

Apart from backward compatibility to prehistoric versions of Excel, the difference I'm aware of is that one is public and one is private. What (if any) are the other differences?

Answer 1

I spent a long time once choosing between the opening variants of these, and we used Auto_Open. The main rationale was because if anyone runs the following code:

Application.EnableEvents = False

... then the Workbook_Open event will not fire. I had a feeling there was another situation where Workbook_Open didn't work either, but I can't remember it now.

I don't have a strong opinion about the close events, but to be honest I'd use the Auto_Close there too. At the end of the day, it's had more testing.
