Description
Obtains a list of the objects in a PowerBuilder library. The information provided is the object name, the date and time it was last modified, and any comments for the object. You can get a list of all objects or just objects of a specified type.
Syntax
LibraryDirectory ( libraryname, objecttype )

Argument |
Description |
|---|---|
|
libraryname |
A string whose value is the name of the PowerBuilder library for which you want the contents. If you do not specify a full path, LibraryDirectory uses the operating system's standard file search order to find the file. |
|
objecttype |
A value of the LibDirType enumerated datatype identifying the type of objects you want listed:
|
Return value
String.
LibraryDirectory returns a tab-separated list with one object per line. The format of the list is:
name ~t date/time modified ~t comments ~n
Returns the empty string ("") if an error occurs. If any argument's value is null, LibraryDirectory returns null.
Usage
If you call LibraryDirectory with a PBD file as the first argument, no comments are displayed because they are not included in PBD files.
You can display the result of LibraryDirectory in a DataWindow control by passing the returned string to the ImportString function for that DataWindow. The DataWindow should contain three string columns. The columns must be wide enough to fit the data in the input string. If not, PowerBuilder reports validation errors.
To return the object's type, use LibraryDirectoryEx.
For an example of parsing tab-delimited data, see the Pos function.
Examples
This code imports the string returned by LibraryDirectory to the DataWindow dw_list and then redraws the dw_list. The DataWindow was defined with an external source and three string columns:
String ls_entries ls_entries = LibraryDirectory( & "c:\pb\dwTemp.pbl", DirUserObject!) dw_list.SetRedraw(FALSE) dw_list.Reset( ) dw_list.ImportString(ls_Entries) dw_list.SetRedraw(TRUE)
