SetLibraryList
PowerScript function
Description
Changes the files in the library search path of the application at
runtime.
Obsolete syntax
You can still use the old syntax with the name of the application
object before the function call: applicationname.SetLibraryList (
filelist).
Syntax

SetLibraryList ( filelist ) |

Argument |
Description |
|---|---|
|
filelist |
A comma-separated list of file names. Specify the full |
Return value
Integer.
Returns 1 if it succeeds. If an error occurs, it returns:
-1 — The application is being run from PowerBuilder, rather than
from a standalone executable.
-2 — A currently instantiated object is in a library that is not on
the new list. If any argument’s value is null, SetLibraryList returns
null.
Usage
When your application needs to load an object, PowerBuilder searches
for the object first in the executable file and then in the dynamic
libraries specified for the application. You can specify a different list
of library files from those specified in the executable with
SetLibraryList.
Calling SetLibraryList replaces the list of library files specified
in the executable with a new list of files. For example, you might use
SetLibraryList to configure the library list for an application containing
many subsystems. You should always use GetLibraryList to return the
current library search path and then append any files you want to add to
this list. You can then pass the complete list in the filelist
argument.
PowerBuilder cannot check whether the libraries you specify are
appropriate for the application. It is up to you to make sure the
libraries contain the objects that the application needs.
The executable file is always first in the library search path. If
you include it in filelist, it is ignored.
If you are running your application in the PowerBuilder development
environment, this function has no effect.
Examples
This example specifies different files in the library search path
based on the selected application subsystem:
|
1 2 3 4 5 6 7 8 9 10 11 |
string ls_list ls_list = getlibrarylist () CHOOSE CASE configuration CASE "Config1" SetLibraryList(ls_list + ",lib1.pbd, lib2.pbd, & lib5.pbd") CASE "Config2" SetLibraryList(ls_list + ",lib1.pbd, lib3.pbd, & lib4.pbd") END CHOOSE |
