DlgDirSelectComboBoxEx
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 |
|
); |
|
Parameters
hDlg
Identifies the
dialog box that contains the combo box.
lpString
Points to the
buffer that is to receive the selected path.
nCount
Specifies the
length, in characters, of the buffer pointed to by the lpString
parameter.
nIDComboBox
Specifies the
integer identifier of the combo box control in the dialog box.
Return Values
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 GetLastError11C2VS7.
Remarks
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).
