About libraries
Contents
Whenever you save an object, such as a window or menu, in a
painter, PowerBuilder stores the object in a library (a PBL file).
Similarly, whenever you open an object in a painter, PowerBuilder
retrieves the object from the library.
Assigning libraries
Application and .NET targets can use as many libraries as you
want. Libraries can be on your own computer or on a server. When you
create a target, you specify which libraries it uses. You can also
change the library search path for a target at any time during
development.
For information about specifying the library search path, see
Specifying
the target’s library search path.
How the information is
saved
Every object is saved in two parts in a library:
-
Source form
This is a syntactic representation of the object, including
the script code. -
Object form
This is a binary representation of the object, similar to an
object file in the C and C++ languages. PowerBuilder compiles an
object automatically every time you save it.
