Replaces the contents of a combo 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 of names can include mapped drive letters.
int DlgDirListComboBoxA( HWND hDlg, LPSTR lpPathSpec, int nIDComboBox, int nIDStaticPath, UINT uFiletype );
A handle to the dialog box that contains the combo box.
A pointer to a buffer containing a null-terminated string that specifies an absolute path, relative path, or file name. An absolute path can begin with a drive letter (for example, d:) or a UNC name (for example, \machinename<i>sharename).
The function splits the string into a directory and a file name. The function searches the directory for names that match the file name. If the string does not specify a directory, the function searches the current directory.
If the string includes a file name, the file name must contain at least one wildcard character (? or ). If the string does not include a file name, the function behaves as if you had specified the asterisk wildcard character () as the file name. All names in the specified directory that match the file name and have the attributes specified by the uFiletype parameter are added to the list displayed in the combo box.
The identifier of a combo box in the hDlg dialog box. If this parameter is zero, DlgDirListComboBox does not try to fill a combo box.
The identifier of a static control in the hDlg dialog box. DlgDirListComboBox 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.
A set of bit flags that specifies the attributes of the files or directories to be added to the combo box. This parameter can be a combination of the following values.
||Includes archived files.|
||Includes subdirectories, which are enclosed in square brackets ([ ]).|
||All mapped drives are added to the list. Drives are listed in the form [-x-], where x is the drive letter.|
||Includes only files with the specified attributes. By default, read/write files are listed even if DDL_READWRITE is not specified.|
||Includes hidden files.|
||Includes read-only files.|
||Includes read/write files with no additional attributes. This is the default setting.|
||Includes system files.|
||If this flag is set, DlgDirListComboBox uses the PostMessage function to send messages to the combo box. If this flag is not set, DlgDirListComboBox uses the SendMessage function.|
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.
If lpPathSpec specifies a directory, DlgDirListComboBox changes the current directory to the specified directory before filling the combo box. The text of the static control identified by the nIDStaticPath parameter is set to the name of the new current directory.
Microsoft Windows NT 4.0 and later: If uFiletype includes the DDL_DIRECTORY flag and lpPathSpec specifies a first-level directory, such as C:\TEMP, the combo 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.
Security Warning: Using this function incorrectly might compromise the security of your program. Incorrect use of this function includes having lpPathSpec indicate a non-writeable buffer, or a buffer without a null-termination. You should review the Security Considerations: Microsoft Windows Controls before continuing.
Microsoft Windows NT 4.0 and later: The list displays long file names, if any.
Windows 95 or later: DlgDirListComboBoxW is supported by the Microsoft Layer for Unicode. To use this, you must add certain files to your application, as outlined in Microsoft Layer for Unicode on Windows Me/98/95 Systems.
