有关wm5.0，directshow中strmbase.lib的问题 [复制链接]

请问，我目前用wm.5.0中的directshow（mfc），出现error LNK2019: unresolved external symbol "public: __cdecl CTransInPlaceFilter::CTransInPlaceFilter(wchar_t *,struct IUnknown *,struct _GUID const &,long *)" (??0CTransInPlaceFilter@@QAA@PA_WPAUIUnknown@@ABU_GUID@@PAJ@Z) referenced in function "public: __cdecl SampleGrabberFilter::SampleGrabberFilter(struct IUnknown *,long *)" (??0SampleGrabberFilter@@QAA@PAUIUnknown@@PAJ@Z)类似错误，在网上找到是因为Treat wchar_t as build-in type需设为no，但mfc要设为yes，该怎么解决呢
