What Is the ATL Control-Hosting API?

http://msdn.microsoft.com/en-us/library/bk2e31we(VS.71).aspx

ATL's control-hosting API is the set of functions that allows any window to act as an ActiveX control container. These functions can be statically or dynamically linked into your project since they are available as source code and exposed by ATL71.dll. The control-hosting functions are listed in the table below.

(ATL's control-hosting API는 윈도우를 ActiveX 컨트롤 컨테이너로 행동할 수 있게금 해주는 함수 셋이다. 내 프로젝트에서  소스코드나 ATL71.dll을 이용하여 정적 or 동적 링크를 사용하여 함수들을 사용할 수 있다. 왜냐하면..로 나와 있기 때문. )

Function	Description
AtlAxAttachControl	Creates a host object, connects it to the supplied window, then attaches an existing control.
AtlAxCreateControl	Creates a host object, connects it to the supplied window, then loads a control.
AtlAxCreateControlLic	Creates a licensed ActiveX control, initializes it, and hosts it in the specified window, similar to AtlAxCreateControl.
AtlAxCreateControlEx	Creates a host object, connects it to the supplied window, then loads a control (also allows event sinks to be set up).
AtlAxCreateControlLicEx	Creates a licensed ActiveX control, initializes it, and hosts it in the specified window, similar to AtlAxCreateControlLic.
AtlAxCreateDialog	Creates a modeless dialog box from a dialog resource and returns the window handle.
AtlAxDialogBox	Creates a modal dialog box from a dialog resource.
AtlAxGetControl	Returns the IUnknown interface pointer of the control hosted in a window.
AtlAxGetHost	Returns the IUnknown interface pointer of the host object connected to a window.
AtlAxWinInit	Initializes the control-hosting code.
AtlAxWinTerm	Uninitializes the control-hosting code.

The HWND parameters in the first three functions must be an existing window of (almost) any type. If you call any of these three functions explicitly (typically, you won't have to), do not pass a handle to a window that's already acting as a host (if you do, the existing host object won't be freed).

The first seven functions call AtlAxWinInit implicitly.

Note   The control-hosting API forms the foundation of ATL's support for ActiveX control containment. However, there is usually little need to call these functions directly if you take advantage of or make full use of ATL's wrapper classes.
