so in solution have 2 projects:

enter image description here

what i'm trying 'show' second 1 through first, this:

enter image description here

i sound total noob... possible? if is, how can achieve this?

both written in c++

thank help.

this complicated question answer in reasonable amount of space. can provide first, assurance has been done possible, , second, broad outline of how proceed.

there 2 approaches possible depending on desired level of integration: windows screensavers standalone exe files. despite can render windows 'preview' dialog. accomplished screensaver.exe being launched preview dialog - passes hwnd on command line.

so - need 3 things

  • convince managed app (cocoshelper) give hwnd form, , launch cocos app command line containing number.
  • in cocos project go appdelegate applicationdidfinishlaunching implementation, , retrieve hwnd command line.
  • you create subclass of windows glviewimpl class, - upon creating opengl view, set parent provided window - applicationdidfinishlaunching method create subclassed glviewimpl rather base cocos version.

the next approach builds on put cocos project same process space host app - assuming host app win32 desktop app.

  • create 3rd "cocosdllproject" clone of "cocosproject" project. change "dynamic library" rather "application" , remove "main.cpp" file.
  • add new "cocosdllmain.cpp" file , add entrypoint function it. "runcocos" or something. make sure method exported dll, , have contents of previous "main" method, should take, parameter, hwnd parameter pass (a modified) appdelegate. parent window.
  • add dll dependency other project, , invoke "runcocos" @ appropriate time.

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
