Error code comparison table

Return value error code

0 means normal
1 Use 1 uniformly to indicate the error, and the rest to see the error report.

The error code of the error report

0: Indicates normal. Generally, as long as it is closed and started normally, the error code and the cause of the error report will be changed to "0" and "normal" respectively.
10: It means that the file has not been saved or written successfully. It is recommended to turn on "Run with administrator rights"
NULL: It means that this error has not been entered. It is recommended to click the issue above to report the bug. We need to provide detailed steps for the error so that we can reproduce the problem and leave the mailbox. If it can't be reproduced, we can contact you by email, and you can take a video for us (because it's really inconvenient for us to complete a computer)

In fact, if it is not entered, it will return NULL as long as it is not found in the table, so the error code I leave in the code is often strange——comeondeweim

We don't know the specific reason, and it may be repaired in the future.
