DlgDirListComboBox

The DlgDirListComboBox function fills the specified combo box with a directory listing. It fills the list with the names of all files, drives, and subdirectories that match the specified attributes and path string.

int DlgDirListComboBox(

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

Parameters

hDlg

Identifies the dialog box that contains the combo box.

lpPathSpec

Points to a null-terminated string of the following form:

[drive:][\]][directory\[...]][filename]

If the specified string includes a drive or directory path, the DlgDirListComboBox function changes the current drive and directory before filling the list. After the list is filled, the drive and directory path are removed from the string specified by the lpPathSpec parameter.

nIDComboBox

Specifies the identifier of a combo box control in a dialog box. If nIDComboBox is zero, the DlgDirListComboBox function assumes no combo box exists and does not attempt to fill it.

nIDStaticPath

Specifies the identifier of the static text control in which the DlgDirListComboBox function is to display the current directory. If nIDStaticPath is zero, DlgDirListComboBox assumes no such control is present.

uFiletype

Specifies the attributes of the files to be displayed. 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.
DDL_POSTMSGS	Posts messages to the application's message queue. By default, the DlgDirList function sends messages directly to the dialog box procedure.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. For example, if the string specified by lpPathSpec is not a valid path, the function fails. To get extended error information, call GetLastError.

Remarks

If the lpszPathSpec parameter points to a zero-length string or to a string specifying a drive, directory, or both but no filename the filename *.* (wildcards) is assumed.

Windows NT:

The directory listing displays long filenames, if any.

Windows 95:

The directory listing displays short filenames (the 8.3 form). You can use the SHGetFileInfo or GetFullPathName functions to get the corresponding long filename.
