  22  * \ingroup Utils
  23  * Extends the CComboBoxEx class with a history of entered
  24  * values. An example of such a combobox is the Start/Run
  25  * dialog which lists the programs you used last in a combobox.
  26  * To use this class do the following:
  27  * -# add both files HistoryCombo.h and HistoryCombo.cpp to your project.
  28  * -# add a ComboBoxEx to your dialog
  29  * -# create a variable for the ComboBox of type control
  30  * -# change the type of the created variable from CComboBoxEx to
  31  *    CHistoryCombo
  32  * -# in your OnInitDialog() call SetURLHistory(TRUE) if your ComboBox
  33  *    contains URLs
  34  * -# in your OnInitDialog() call the LoadHistory() method
  35  * -# in your OnOK() or somewhere similar call the SaveHistory() method
  36  *
  37  * thats it.
