CB_DIR

An application sends a CB_DIR message to add a list of filenames to the list box of a combo box.

CB_DIR

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

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

Parameters

uAttrs

Value of wParam. Specifies the attributes of the files to be added to the list box. It can be any combination of the following values:

Value	Meaning
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 any wildcards (for example, *.*), all files that match 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 CB_ERR. If insufficient space is available to store the new strings, it is CB_ERRSPACE.
