Type: Array
Specifies the name of the array.

Return Value

Type: DWord
The names of all open databases are placed into a variable array.

If the array you specify doesn't exist, X# automatically creates the array. If the array exists and isn't large enough to contain all the database information, X# automatically increases the size of the array to accommodate the information. If the array is larger than necessary, X# truncates the array. If the array exists and ADatabases( ) returns 0 because no databases are open, an existing array remains unchanged. If the array doesn't exist, and ADatabases( ) returns 0, the array is not created.

ADatabases( ) creates a two-dimensional array. The first column of the array contains the names of the open databases, and the second column contains the paths to the databases.
ADatabases( ) returns the number of database names (rows) in the array. If no databases are open, ADatabases( ) returns 0 and the array isn't created.
