c# - Passing an unmanaged pointer between two AppDomains (By indirect call) -


.net 4.5, 64bit win8

i have 2 msmq running under wcf , hosted under windows activation service.

  1. execute msmq: responsible calling unmanaged function , obtaining pointer intptr 4gb array in addition other limited size variables. array not important , shouldn't blocking queue until passed db , having queue free priority. passing pointer save msmq (hypothesis).
  2. save msmq: should save array db across network deallocate unmanaged memory.

the problem here be:

  1. making sure array deallocated on poison messages , other queue errors. case easy bit.
  2. passing intptr cross app domains might not possible, recall, old days, pointer values relative (and word offsetting comes mind, or maybe mixing processes , appdomains) app domains , security reasons .net might not allow this? is possible or dreaming, cross domain issue or problem have different title?

n.b. have used netpipes communication before, has queue in middle, netpipes not solution.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
