CComboBox myComboBox; int count = myComboBox.GetCount();
int count = m_myComboBox.GetCount();This code assumes that there is a combo box control already created in the application, and stored in the m_myComboBox variable. It calls the GetCount method on this existing control to retrieve the number of items in the combo box. The package library used for this code is MFC (Microsoft Foundation Classes), which is a C++ library that provides a set of classes for developing Windows applications.
