描述:
在IHWM类型库中定义的myEnum想在IHWD组件中也使用。
在IHWD.idl中使用importlib("IHWM.TLB");的话，在编译IHWD.h时会提示找不到myEnum的定义。
在IHWD.idl中使用import("IHWM.idl");的话，在编译时会提示:
E:\Program Files\Microsoft Visual Studio\VC98\ATL\INCLUDE\atlcom.h(1827) : error C2259: 'CComObject<class CThermoPrinter>' : cannot instantiate abstract class due to following members:

这应该怎么解决呢？
