此基础示例展示如何使用不同的 COM 接口映射项宏。此示例使用 Visual C++ 本机编译器 COM 支持的聪明指针机制 (_com_ptr_t)。使用 #import 机制（而不使用 MIDL 生成的 .h 文件和 .c 文件）提供封送处理信息。-The basis of this example demonstrate how to use a different COM interface map of macros. This example uses Visual C++ The local compiler support for COM smart pointer mechanism (_com_ptr_t). The use of# Import mechanism (instead of using MIDL generated. H files and. C file) to provide marshaling information.

This sample creates a button that displays itself with one of three different bitmaps, depending on its state. The button has a bitmap for: the unpushed state; the hover state (when the mouse moves over the button); and the pushed state. Default bitmaps are included with the sample, but you can override these properties to use your own bitmaps.-This sample creates a button that displays itself with one of three different bitmaps, depending on its state.

COM组件是动态连接的，而且COM组件是完全与语言无关的。同时，COM组件可以以二进制的形式发布。COM组件还可以在不妨碍老客户的情况下被升级成新的版本。 -COM component is a dynamic connection, and COM components and language is completely unrelated. At the same time, COM components can be in binary form. COM components can also be without prejudice to the case of the old customers have been upgraded into a new version.
