LB_DIR Overview  Group

An application sends an LB_DIR message to add a list of filenames to a list box.

LB_DIR 

wParam = (WPARAM) (UINT) uAttrs;          // file attributes 

lParam = (LPARAM) (LPCTSTR) lpszFileSpec; // filename address 

 

Parameters

uAttrs

Value of wParam. Specifies the attributes of the files to be added to the list box. This parameter can be a combination of the following values:

Value	Description
DDL_ARCHIVE	Includes archived files.
DDL_DIRECTORY	Includes subdirectories. Subdirectory names are enclosed in square brackets ([ ]).
DDL_DRIVES	Includes drives. Drives are listed in the form [-x-], where x is the drive letter.
DDL_EXCLUSIVE	Includes only files with the specified attributes. By default, read-write files are listed even if DDL_READWRITE is not specified.
DDL_HIDDEN	Includes hidden files.
DDL_READONLY	Includes read-only files.
DDL_READWRITE	Includes read-write files with no additional attributes.
DDL_SYSTEM	Includes system files.

lpszFileSpec

Value of lParam. Points to the null-terminated string that specifies the filename to add to the list. If the filename contains wildcards (for example, *.*), all files that match the wildcards and have the attributes specified by the uAttrs parameter are added to the list.

Return Values

The return value is the zero-based index of the last filename added to the list. If an error occurs, the return value is LB_ERR. If there is insufficient space to store the new strings, the return value is LB_ERRSPACE.
