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.
