ComboBox_Dir macro (windowsx.h)

Adds names to the list displayed by a combo box. The macro adds the names of directories and files that match a specified string and set of file attributes. It can also add mapped drive letters to the list in a combo box. You can use this macro or send the CB_DIR message explicitly.

Syntax

int ComboBox_Dir(
   HWND    hwndCtl,
   UINT    attrs,
   LPCTSTR lpszFileSpec
);

Parameters

hwndCtl

Type: HWND

A handle to the control.

attrs

Type: UINT

The attributes of the files or directories to be added to the list in a combo box. For more information, see CB_DIR.

lpszFileSpec

Type: LPCTSTR

A pointer to the 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, \ machinename\ sharename).

Return value

Type: int

If the message succeeds, the return value is the zero-based index of the last name added to the list. If an error occurs, the return value is CB_ERR. If there is insufficient space to store the new strings, the return value is CB_ERRSPACE.
