// DrvListBox.h - header file for the CDrvListBox class
//
// A CDrvListBos is a drop down list box which shows all drives on the local
// computer with the same icons and names as the explorer. This control is
// derived from CComboBoxEx. Use it instead of a CComboBoxEx and call
// LoadItems in the OnInitDialog() of the parent dialog. By default, small
// icons are displayed but you may specify ( true ) as parameter to LoadItems
// to request the large icons. This will also increase the size of your edit
// box! GetDataPtr will retrieve a pointer a string containing the root path
// (e.g. for "Harddisk1 (C:)" this would be "C:\").
