i have page, example, /about . in page's view may set page title: $this->title = "abc" - works ok. also have header component in /components own view /components/views/header.php how change page title component's view? $this->title not work because i'm in component's view, not page. not sure how calling component, change title need specify want change current view. here example, in view add (or use method used make sure insert view parameter): mycomponent::changetitle($this); and in component (whatever method want this): public static function changetitle($view) { $view->title = 'changed'; } if not related situation, please add example of view , component can understand better scenario.

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(&targetp...

in our application maintained years use binaryformatter serialization of big data objects containing loads of collections , circular references. serialization takes forever (~20 seconds) , takes of cpu usage. i'd switch type of serialization better , light without changing code there not time given. i've tried many of solutions of them need: class decorating or many code changes (e.g. protobuf ); doesn't allow circular references (e.g msgpack ); is there way smoothly switch , better serializer without pain , improve serialization process? after doing research , spending day on implementing available solutions - i'll go json.net . i didn't have change switch binaryformatter, serializer attributes objects haven't change. runs way faster (~2 seconds same object size) , seems work properly. to pass circular references , other errors had configure serializer: jsonserializer serializer = new jsonserializer(); serializer.converters.add(new j...
