We often encounter the following mistakes:
Microsoft Jet Database Engine Error '80004005'
The context is invalid or closed. There is also an error prompt such as a similar database of unrecognizable format.
The reason is: When your Access database is an ASP suffix, when it is uploaded to space, it is very likely that the server adds some information, which leads to this database file, so the server cannot be identified. In particular, when the server operating system is Windows 2003. The error rate is 100%.
Workaround: Turn the database to the MDB suffix format locally, upload, then change the suffix back to the ASP after uploading.
When I met this problem, I was depressed for a day. Finally found a solution on the Internet, but seeing this method is not a lot of people noticing, so I wrote it, I hope to help everyone.
