20.2.3..Combo Box Methods..........................................................................

A combo box is based on the CComboBox class. Therefore, if you want to dynamically

create this control, declare a variable or a pointer to CComboBox using its default

constructor. To initialize the control, call its Create() method. Here is an example:

BOOL CExerciseDlg::OnInitDialog()

{

CDialog::OnInitDialog();

SetIcon(m_hIcon, TRUE); // Set big icon

SetIcon(m_hIcon, FALSE); // Set small icon
