DirectShow Source Filter

I have created directShow Source filter, it tested on W开发者_运维知识库in32, and works fine. But when I port them on windows Mobile 6.5.3

After calling CoCreateInstance(MyfilterGUID), I have such:

hr  0x8007007e {The specified module could not be found. }  HRESULT

Why this happens? I suppose this because something wrong with my DirectShow dll.

I resolve this issue, that's happens because, my DLL has dependencies from MS dll msvcr80d.dll. To fix this needed in Visual Studio Project Properties -> General -> Use of MFC set Use MFC in a Static Library. And all works...
