c++ - OpenGL Auxiliary buffers -

-

i'm working on project using opengl, c++ , windows, i've been debugging amds codexl , noticed there's 4 full resolution "auxiliary buffers" alongside front, back, depth , stencil buffers. far can tell these totally unused , taking memory, wondered if there's way not initialize them, or perhaps more codexl erroneously reporting initialized?

as far can tell, know code side pixelformatdescriptor has flags auxiliary , accumulation buffers, both of set zero.

i wondered if else has experienced , if it's avoidable @ (perhaps these buffers required).

thanks

update:

tried out "proper" context creation link, better since it's explicit in version conformity, did not resolve issue. ended trying loop passing counter index describepixelformat() try match format 0 aux buffers , rest of need, couldn't find supported , worked, here's code search (just basic test).

        pixelformatdescriptor targetpixfmt;          memset(&targetpixfmt, 0, sizeof(pixelformatdescriptor));         targetpixfmt.nsize = sizeof(pixelformatdescriptor);         targetpixfmt.nversion = 1;         targetpixfmt.dwflags = pfd_doublebuffer | pfd_support_opengl | pfd_draw_to_window;         targetpixfmt.ipixeltype = pfd_type_rgba;         targetpixfmt.ccolorbits = colorbitdepth;         targetpixfmt.cdepthbits = depthbitdepth;         targetpixfmt.cstencilbits = stencilbitdepth;          s32 pixfmtcounter = 1; // starting @ 0 fails ?          (;;)         {             pixelformatdescriptor temppixfmt;              if (0 == describepixelformat(m_devicecontext, pixfmtcounter,                 sizeof(pixelformatdescriptor), &temppixfmt))                 break;              if ((temppixfmt.dwflags & targetpixfmt.dwflags) == targetpixfmt.dwflags &&                 targetpixfmt.ipixeltype == temppixfmt.ipixeltype &&                  targetpixfmt.ccolorbits <= temppixfmt.ccolorbits &&                 targetpixfmt.cdepthbits <= temppixfmt.cdepthbits &&                 temppixfmt.cauxbuffers <= 0)             {                 break;             }              pixfmtcounter++;         }

i'm being loose color , depth bits try , more results, search finds 2 formats, both of have dwflags set 33893 (pfd_doublebuffer | pfd_draw_to_window | pfd_support_opengl | pfd_generic_format | pfd_swap_copy | pfd_support_composition).

if use format first call opengl function fails because null , pixel format change between failing , not.

i guess that's way is?

reactjs - React router and this.props.children - how to pass state to this.props.children -

-
i'm using react-router first time , don't know how think in yet. here's how i'm loading components in nested routes. entry point .js reactdom.render( <router history={hashhistory} > <route path="/" component={app}> <route path="models" component={content}> </route> </router>, document.getelementbyid('app') ); app.js render: function() { return ( <div> <header /> {this.props.children} </div> ); } so child of app content component sent in. i'm using flux , app.js has state , listens changes, don't know how pass state down this.props.children. before using react-router app.js defines children explicitly, passing state natural don't see how now. using couple of react helper methods can add state, props , whatever else this.props.children render: function() { var children = react.ch...

i have excel workbook used generate quotations customers. there main page user inputs data, , there buttons generate various pdfs , send them customer. however, 1 user consistently getting error preventing generating , sending pdfs. i beleive "microsoft windows common controls 6.0 (sp6)". it's installed on users' computers. on mine, location "c:\windows\syswow64\mscomctl.ocx" on others "c:\windows\system32\mscomctl.ocx" the user experiencing issues on 32-bit machine, "mscomctl.ocx" file should in system32. have manually put in there, , pointed common controls reference in vba it. issue seems keep reverting looking in syswow64. since folder doesn't exist, can't find it, , can't produce pdfs. i thought perhaps issue user running older version of office (2007) there users on 2013 , 2016. thought perhaps mixture of 64-bit , 32-bit users. user gets sent workbook other users (as quotation process goes further, gets passed ...
