The DlgDirSelectComboBoxEx function retrieves the current selection from a combo box filled by using the DlgDirListComboBox function. The selection is interpreted as a drive letter, a file, or a directory name.
BOOL DlgDirSelectComboBoxEx(
HWND hDlg, |
// handle to dialog box with list box |
LPTSTR lpString, |
// pointer to buffer for path string |
int nCount, |
// number of characters in path string |
int nIDComboBox |
// identifier of combo box |
); |
If the current selection is a directory name, the return value is nonzero.
If the current selection is not a directory name, the return value is zero. To get extended error information, call GetLastError.
If the current selection specifies a directory name or drive letter, the DlgDirSelectComboBoxEx function removes the enclosing square brackets (and hyphens for drive letters) so the name or letter is ready to be inserted into a new path or filename. If there is no selection, the contents of the buffer pointed to by lpString do not change.
The DlgDirSelectComboBox function does not allow more than one filename to be returned from a combo box.
DlgDirSelectComboBoxEx sends CB_GETCURSEL and CB_GETLBTEXT messages to the combo box.
In the Win32 API, you can use this function with all three types of combo boxes (CBS_SIMPLE, CBS_DROPDOWN, and CBS_DROPDOWNLIST).
CB_GETCURSEL, CB_GETLBTEXT, DlgDirListComboBox, DlgDirSelectEx
