DlgDirList

The DlgDirList function fills the specified list box with the names of all files matching the specified path or filename.

int DlgDirList(

HWND hDlg,	// handle to dialog box with list box
LPTSTR lpPathSpec,	// pointer to path or filename string
int nIDListBox,	// identifier of list box
int nIDStaticPath,	// identifier of static control
UINT uFileType	// file attributes to display
);

Parameters

hDlg

Identifies the dialog box that contains the list box.

lpPathSpec

Points to a null-terminated string that contains the path or filename. DlgDirList modifies this string, which should be long enough to contain the modifications. For more information about this parameter, see the Remarks section.

nIDListBox

Specifies the identifier of a list box. If this parameter is zero, DlgDirList assumes that no list box exists and does not attempt to fill one.

nIDStaticPath

Specifies the identifier of the static control used for displaying the current drive and directory. If this parameter is zero, DlgDirList assumes that no such control is present.

uFileType

Specifies attributes of the filenames to be displayed. This parameter must be one or more 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.
DDL_POSTMSGS	Posts messages to the application's message queue. By default, DlgDirList sends messages directly to the dialog box procedure.

Return Values

If a listing is made even an empty listing the return value is nonzero. If the input string does not contain a valid search path, the return value is zero.

Remarks

If you specify a zero-length string for the lpPathSpec parameter or if you specify only a directory name with no filename, the string will be changed to *.*

The lpPathSpec parameter has the following form:

[drive:] [[\u]directory[\idirectory]\u] [filename]

In this example, drive is a drive letter, directory is a valid directory name, and filename is a valid filename that must contain at least one wildcard (? or *).

If lpPathSpec includes a drive or directory name, or both, the current drive and directory are changed to the specified drive and directory before the list box is filled. The static control identified by the nIDStaticPath parameter is also updated with the new drive or directory name, or both.

After the list box is filled, DlgDirList updates lpPathSpec by removing the drive or directory portion, or both, of the path and filename.

DlgDirList sends the LB_RESETCONTENT and LB_DIR messages to the list box.
