How to Use CComboBox in Ribbon

Hi;

My existing application has an Owner draw ComboBoxEx , which is derived from CComboBox.

Now i switched my Application to Ribbon , Please tell me how can i used that older ComboBoxEx class with minimum alteration.So that my Ribbon supports that combo , and handles the Selchnage event.

*My combobox is created at runtime , and may be have more than one instance.

Thnx

Hi Oleg ;
Thnx for ur quick response.
i did this :
CComboBoxEx *pControlClass;
          pControlClass = new CComboBoxEx();
          pControlClass->Create(rect,this);
          CXTPControlCustom* pCustomControl = (CXTPControlCustom*)CXTPControlCustom::CreateObject();
          pCustomControl->SetControl(pControlClass);
          pGroup->Add(pCustomControl, nID);


it is working fine ..
thnx
