Objects created by the ATL for Windows CE Object Wizard

You can use the Windows CE ATL Object Wizard to create the following types of object:

• Simple objects

  Simple objects initially implement only the IUnknown and, optionally, the IDispatch, ISupportErrorInfo, and IConnectionPointContainer interfaces. You can add other interfaces after inserting the simple object into your project, but you must provide the implementation for those methods.

• Internet Explorer objects

  Microsoft® Internet Explorer objects implement all the interfaces implemented by simple objects. They also implement the IObjectWithSite interface, which is required for objects used in Web pages. These objects are compatible with the Microsoft® Windows® CE Pocket Internet Explorer as well as the Internet Explorer for desktop platforms.

• Full controls

  Full controls implement all the interfaces implemented by Internet Explorer controls, except for IObjectWithSite. They also implement the IProvideClassInfo2, IPersistStorage, IQuickActivate, IDataObject, and ISpecifyPropertyPages interfaces.

• Lite controls

  Internet Explorer controls, known as Lite controls, implement all the interfaces implemented by Internet Explorer objects. They also implement the IPersistStreamInit, IOleControl, IOleObject, IOleInPlaceActiveObject, and IViewObjectEx interfaces and, optionally, the IOleInPlaceObjectWindowless interface.

• Composite controls

  Composite controls are derived from CComCompositeControl and are hosted by a standard dialog box. Composite controls are ActiveX controls designed to contain other controls, including Windows and ActiveX controls.

• Lite composite controls

  Lite composite controls can host other controls, but they support only the interfaces needed by Internet Explorer.

Controls inherit from the ATL CComControl class, which provides a number of helper functions that are necessary for controls. These controls are compatible with the Windows CE Pocket Internet Explorer as well as the Internet Explorer for desktop platforms.

You also can use the Windows CE ATL Object Wizard to create dialog boxes, property pages, and a component registrar for your server. A component registrar is an object that can register and deregister individual components in a DLL.
