@ Mcfer: If you don't know what you know, sometimes the reply will become boring. 1. You understand English. 2. Do not understand programming. (Modify, you know FileSystemWatcher, you should understand programming) 3. You can connect to ACCESS through OLEDB, but it is not guaranteed to be connected when it is occupied by other programs. 4. ACCESS is a relatively unstable number.

1. You understand English.
2. Do not understand programming. (Modify. You know FileSystemWatcher. you should understand programming)
3. ACCESS can be connected through OLEDB, but it is not guaranteed to be connected when it is occupied by other programs.
4. ACCESS is a relatively unstable database. If many connections and illegal operations occur, file errors may occur.
5. Although the official website does not support ACCESS for multi-user connection, it can still be broken through.
If I or my friends tried to use ACCESS to develop and sell more than 0.1 million of the price (for a single customer), I found it boring, SQL Server is useless.
6. After successful ACCESS connection, ACCESS does not have a notification mechanism to tell you which data table has changed.
7. If the data table has a field such as the modification time, this will be easy. If not, it would be hard to do...
8. It is similar to wanting to know the whereabouts of your child at any time. If this is a market, someone will make a 360 bracelet.
If it is a single customer requirement, the labor cost required to solve this problem is far greater than the customer (or you)
Fees.
9. Although I always wanted to be modest, I should be able to count the two ACCESS hands in the garden.
