c# - How to cast a CodeDOM object into its correct type -


i have code generates array of tuples of codecompileunit , codetypedeclarations of different classes. after generate array want able invoke , create instance of given member of array. however, can't seem figure out how name , type of class defined in codetypedeclaration.

var tuple = factory.createtuple(...);  var provider = new csharpcodeprovider(); var parameters = new compilerparameters                     {                         generateinmemory = true,                         includedebuginformation = true                     }; var results = provider.compileassemblyfromdom(parameters, tuple.getcodecompileunit()); var runtimeobj = (????tuple.getcodetypedeclaration().gettype()???)activate.createinstance(results.compileassembly.gettype(tuple.getcodetypedeclaration().name)); runtimeobj.dostuff();

any thoughts on how this?

there no way can cast dynamically created type.

i see 2 options here:

  1. make generated type implement non-generated interface , cast that:

    var runtimeobj = (icandostuff)activate.createinstance(…); runtimeobj.dostuff();

  2. use dynamic or reflection invoke method:

    dynamic runtimeobj = activate.createinstance(…); runtimeobj.dostuff();

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...
