You can open a library database and test it just like any other database. Although you always should begin testing the library functions this way, it also is important that you give the database a test drive as a library. In other words, after you eliminate any bugs from the database, you should reference it from another database and test it as a library database.If you need to make changes to a library database while accessing it from another database, you can do so easily by following these steps:
Make sure that you have referenced the library database in Tools, References.
Click the Object Browser tool from the Module Design window.
From the Project/Library drop-down menu, select the library database that contains the code you want to modify (see Figure 24.8).
Figure 24.8. Use the Object Browser to modify a library database.
Select the class you want to modify from the Classes list box.
Select the member you want to modify from the Members list box.
Click View Definition (the button with the arrow pointing toward the box), or double-click the member whose code you want to view. Access places you in the correct module and procedure of the library database. You can now make changes to the code in the database as required.
