BOOL Create( DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID );
Return Value
Nonzero if successful; otherwise 0.
Parameters
dwStyle
Specifies the style of the combo box. Apply any combination of combo-box styles to the box.
rect
Points to the position and size of the combo box. Can be a RECT structure or a CRect object.
pParentWnd
Specifies the combo box’s parent window (usually a CDialog). It must not be NULL.
nID
Specifies the combo box’s control ID.
Remarks
You construct a CComboBox object in two steps. First call the constructor, then call Create, which creates the Windows combo box and attaches it to the CComboBox object.
When Create executes, Windows sends the WM_NCCREATE, WM_CREATE, WM_NCCALCSIZE, and WM_GETMINMAXINFO messages to the combo box.
These messages are handled by default by the OnNcCreate, OnCreate, OnNcCalcSize, and OnGetMinMaxInfo member functions in the CWnd base class. To extend the default message handling, derive a class from CComboBox, add a message map to the new class, and override the preceding message-handler member functions. Override OnCreate, for example, to perform needed initialization for a new class.
Apply the following window styles to a combo-box control. :
