The Cxtflatcombobox class is a member of the Codejoke Developer Kit Xtreme Toolkit. Anyone can use the source code for this class for free.

How to use:

Add the header file XTFlatComboBox.h and implementation file XTFlatComboBox.cpp of the Cxtflatcombobox class to the project, and then include the header file in the file that uses the class:#include "XTFlatComboBox.h"

Then declare the class instance in the implementation file, and you can add a CComboBox member variable with the Class Wizard (Classes Wizard): (Class Wizard-> membership Variables Tab-> add Variable). Then change the CComboBox to Cxtflatcombobox. Member variables are used primarily to control the combo box.

This example is a typical dialog box based program, the dialog box has two combo boxes, each combo box has a check button to control its shielding status, editable combo box with a "AutoComplete" function control. Figure one is the running picture of this example program:
