c++ - Create a custom class for this directshow system, cant figure out how -


i'm trying learn directshow, , computer vision opencv. keep code cleaner want "put away" (create class) directshow code i've borrowed internet. code is: http://alax.info/trac/public/browser/trunk/utilities/setlifecamstudioresolutionsample/setlifecamstudioresolutionsample.cpp

okay. in vc++ project, create new class. call "directshowclass", have directshowclass.h & .cpp.

the problem have cant figure out how take care of parts in code.

everything in _tmain() put in 1 function. 1 okay.

but do with:

ccomptr<ipin> getpin(ibasefilter* pbasefilter, size_t nindex = 0) {     .... }

and:

#pragma region formerly located in qedit.h in windows sdk, obsoleted , defined within project  struct __declspec(uuid("0579154a-2b53-4994-b0d0-e773148eff85")) isamplegrabbercb : iunknown {     //     // raw methods provided interface     //        virtual hresult __stdcall samplecb (double sampletime,struct imediasample * psample ) = 0;       virtual hresult __stdcall buffercb double sampletime,unsigned char * pbuffer, long bufferlen ) = 0; };  struct __declspec(uuid("6b652fff-11fe-4fce-92ad-0266b5d7c78f")) isamplegrabber : iunknown {     //     // raw methods provided interface     //        virtual hresult __stdcall setoneshot (         long oneshot ) = 0;       virtual hresult __stdcall setmediatype (         struct _ammediatype * ptype ) = 0;       virtual hresult __stdcall getconnectedmediatype (         struct _ammediatype * ptype ) = 0;       virtual hresult __stdcall setbuffersamples (         long bufferthem ) = 0;       virtual hresult __stdcall getcurrentbuffer (         /*[in,out]*/ long * pbuffersize,         /*[out]*/ long * pbuffer ) = 0;       virtual hresult __stdcall getcurrentsample (         /*[out,retval]*/ struct imediasample * * ppsample ) = 0;       virtual hresult __stdcall setcallback (         struct isamplegrabbercb * pcallback,         long whichmethodtocallback ) = 0; };  struct __declspec(uuid("c1f400a0-3f08-11d3-9f0b-006008039e37")) samplegrabber;     // [ default ] interface isamplegrabber  #pragma endregion  #undef atlensure_succeeded #define atlensure_succeeded(x) { hresult __a = (x); if(failed(__a)) { _tprintf(_t("error 0x%08x in line %d\n"), __a, __line__); atlthrow(__a); } }

how declare them in .h file? , .cpp file.

the second fragment (#pragma region/endregion) ok included on .h in project, visible code needs it.

the first fragment static function. can copy of classes, or can add "inline" specifier right before "ccomptr getpin..." on first line , again leave on .h file.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
