What Is Access Database Library?

When the Access database is programmed using VBA code to manage other application objects which are external to the Access database you need to allow permission to use each application’s respective library files. Then only the VBA will work between the Access database and other external applications. These libraries not only give a security layer but also control the complete access of all the objects.

Here are some more interesting reasons for using Access database libraries:

• Increases the performance by running or loading your application at a faster pace.
• Enhances the Access database memory usage
• Offers the best security for keeping your intellectual property completely safe.
• Easy sharing of database projects across multiple developers.
• Gives stability to the Access database front-end.
• It’s been so easy to maintain as the code size of the Access database front end is less complex and small. Thus there will be fewer chances of Access database corruption.

Understanding Automation Error Library Not Registered Access:

• Press Window + R button from your keyboard and in the opened run dialog box type regsvr32 along with the complete library file path. Like this:

regsvr32 “c:\program files\common files\microsoft shared\dao\dao360.dll”

• Most of the time it is seen that the Access library not registered error won’t resolve until the library is unregistered and then re-registered.

So here is the code that you need to use for unregistering the problem-causing library.

regsvr32 -u “c:\program files\common files\microsoft shared\dao\dao360.dll”

• After completing the process of unregistering now re-register it with the above-given code.
