Параметры

[in] lpszClassName
A null-terminated character string that contains the name of the Windows class (a WNDCLASS structure). The class name can be any name registered with the global AfxRegisterWndClass function or any of the predefined control-class names. If null, uses the default CWnd attributes.
[in] lpszWindowName
A null-terminated character string that contains the window name.
[in] dwStyle
Specifies the window style attributes. WS_POPUP cannot be used. If you wish to create a pop-up window, use CWnd::CreateEx instead.
[in] Rect
The size and position of the window, in client coordinates of pParentWnd.
[in] pParentWnd
The parent window.
[in] nID
The ID of the child window.
[in] pContext
Pointer to an optional CCreateContext structure used to override portions of the creation process.

Заметки

You construct a child window in two steps. First, call the constructor, which constructs the CWnd object. Then call Create, which creates the Windows child window and attaches it to CWnd. Create initializes the window's class name and window name and registers values for its style, parent, and ID. During this process, Create calls the function CWnd::PreCreateWindow.

For a list of the predefined control-class names available for the lpszClassName parameter, refer to About Window Classes.

Пример

// Dynamically create static control using CWnd::Create,
// instead of with CStatic::Create, which doesn't
// need the "STATIC" class name.
void CMyDlg::OnCreateStatic() 
{
   // m_pWndStatic is a CWnd* member of CMyDlg
   m_pWndStatic = new CWnd;
   m_pWndStatic->Create(_T("STATIC"), _T("Hi"), WS_CHILD | WS_VISIBLE,
       CRect(0, 0, 20, 20), this, 1234);
