When working with Data Access Objects from Microsoft Access, you will often need a Database object variable that represents the current database. Use the CurrentDb function to return a Database object for the database that is currently open. This Database object is automatically appended to the Databases collection.
For example, suppose you are currently working with the Northwind sample database in Microsoft Access. You can create a Database object that refers to that database by first declaring a Database object variable, then pointing it to the Database object returned by the CurrentDb function.
Dim dbs As Database
Set dbs = CurrentDbYou don't need to know the name of the database or its position in the Databases collection in order to use the current database. If you do want to know the name of the current database, check the Name property of the Database object, which contains the path and file name of the database. To find its position in the Databases collection, enumerate through the collection.
You can open only one database at a time in the Microsoft Access window. From Visual Basic code, however, you can create multiple independent Database object variables to represent multiple open databases. In this way, you can manipulate more than one database at a time from code. You can also create multiple Database object variables and point them to the current database.
Note In your Visual Basic code, use the CurrentDb function to return a Database object that refers to the current database, rather than the DBEngine(0)(0) syntax. The CurrentDb function creates another instance of the current database, while the DBEngine(0)(0) syntax refers to the open copy of the current database. Using the CurrentDb function enables you to create more than one variable of type Database that refers to the current database. Microsoft Access still supports the DBEngine(0)(0) syntax, but you should consider making this modification to your code in order to avoid possible conflicts in a multiuser environment.
