有高手能解释一下下面的程序吗？
class CDataCombo : public CWnd{
protected:
DECLARE_DYNCREATE(CDataCombo)
public:
CLSID const& GetClsid()
{
static CLSID const clsid
= { 0xf0d2f21c, 0xccb0, 0x11d0, { 0xa3, 0x16, 0x0, 0xaa, 0x0, 0x68, 0x8b, 0x10 } };
return clsid;
}
virtual BOOL Create(LPCTSTR lpszClassName,
LPCTSTR lpszWindowName, DWORD dwStyle,
const RECT& rect,
CWnd* pParentWnd, UINT nID,
CCreateContext* pContext = NULL)
{ return CreateControl(GetClsid(), lpszWindowName, dwStyle, rect, pParentWnd, nID); }
BOOL Create(LPCTSTR lpszWindowName, DWORD dwStyle,
const RECT& rect, CWnd* pParentWnd, UINT nID,
CFile* pPersist = NULL, BOOL bStorage = FALSE,
BSTR bstrLicKey = NULL)
{ return CreateControl(GetClsid(), lpszWindowName, dwStyle, rect, pParentWnd, nID,
pPersist, bStorage, bstrLicKey); }

顺便问一下CDataCombo类怎么用的？
