About libraries
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, component, 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
formThis 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.
