DlgDirListA function (winuser.h)

Replaces the contents of a list box with the names of the subdirectories and files in a specified directory. You can filter the list of names by specifying a set of file attributes. The list can optionally include mapped drives.

Syntax

int DlgDirListA(
  [in]      HWND  hDlg,
  [in, out] LPSTR lpPathSpec,
  [in]      int   nIDListBox,
  [in]      int   nIDStaticPath,
  [in]      UINT  uFileType
);

Parameters

[in] hDlg

Type: HWND

A handle to the dialog box that contains the list box.

[in, out] lpPathSpec

Type: LPTSTR

A pointer to a buffer containing a null-terminated string that specifies an absolute path, relative path, or filename. An absolute path can begin with a drive letter (for example, d:) or a UNC name (for example, \<i>machinename\sharename).

The function splits the string into a directory and a filename. The function searches the directory for names that match the filename. If the string does not specify a directory, the function searches the current directory.

If the string includes a filename, the filename must contain at least one wildcard character (? or *). If the string does not include a filename, the function behaves as if you had specified the asterisk wildcard character (*) as the filename. All names in the specified directory that match the filename and have the attributes specified by the uFileType parameter are added to the list box.

[in] nIDListBox

Type: int

The identifier of a list box in the hDlg dialog box. If this parameter is zero, DlgDirList does not try to fill a list box.

[in] nIDStaticPath

Type: int

The identifier of a static control in the hDlg dialog box. DlgDirList sets the text of this control to display the current drive and directory. This parameter can be zero if you do not want to display the current drive and directory.

[in] uFileType

Type: UINT

Specifies the attributes of the files or directories to be added to the list box. This parameter can be one or more of the following values.

Return value

Type: int

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 .

Remarks

If lpPathSpec specifies a directory, DlgDirListComboBox changes the current directory to the specified directory before filling the list box. The text of the static control identified by the nIDStaticPath parameter is set to the name of the new current directory.

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

If uFileType includes the DDL_DIRECTORY flag and lpPathSpec specifies a first-level directory, such as C:\TEMP, the list box will always include a ".." entry for the root directory. This is true even if the root directory has hidden or system attributes and the DDL_HIDDEN and DDL_SYSTEM flags are not specified. The root directory of an NTFS volume has hidden and system attributes.

The directory listing displays long filenames, if any.
