i've looked @ how can create instance of derived class instance of base class , include private fields? , create instance of derived class base class either i'm not getting it, or they're not quite i'm looking for. i have class, derived another, implementing particular interface: public class derivedclass : baseclass, iderivedclass baseclass implements ibaseclass , iderivedclass inherits ibaseclass . sometimes, want able initialize derived class, when have instance of base class. create constructor copies each of properties instance of base properties of instance of derived class, there way? along lines of: baseclass bc = new baseclass(); derivedclass dc = new derivedclass() : bc; is do-able? if not, why not? i'm prepared accept might not possible, if so, i'd quite interested if can explain why. no, not possible. you have create object since has have characteristics of second object. can't copy 1 another. might object invalid

i trying replace delphi clientdatasets worked fine slow on large data firedac memorytables create firedac memory table in data module , populate form. in form check record count of memory table , contains records. close memory table , reopen returns empty table after opening. dataform.mtdebtran.filename := cdsdir + '/debtran.fds'; dataform.mtdebtran.createdataset dataform.mtdebtran.createdataset; dataform.mtdebtran.open; dataform.builddebtrantemp1(p1,p2,p3,p4,true,true); dataform.mtdebtran.savetofile(cdsdir + '/debtran',sfbinary); showmessage(inttostr(dataform.mtdebtran.recordcount)); dataform.mtdebtran.close; dataform.mtdebtran.open; showmessage(inttostr(dataform.mtdebtran.recordcount));` is real code, , complete? you're calling createdataset twice in succession dataform.mtdebtran.createdataset dataform.mtdebtran.createdataset; for no apparent reason, anyway if mtdebtran dataset supposed contain data before first call createdataset, call em

i want use rotated image in mvc application. purpose worte controller returns rotated image, cant working. this command: public actionresult picturestreamrotate(string filename) { image image = image.fromfile(filename); image.rotateflip(rotatefliptype.rotate90flipnone); memorystream stream = new memorystream(); image.save(stream, imageformat.jpeg); return file(stream, "image/jpeg"); } the image streamed invalid. dies have idea. input picture jpg file. btw. if remove thw line image.rotateflip wont work. this happens because stream's position after written data. toarray() get's in stream start. alternatively, set position 0 or seek start of image data. try in linqpad: var x = new memorystream(); x.writebyte(123); x.readbyte().dump(); it gives -1 result... then x.position=0; and 123 back. btw, toarray() copies data, not want, guess.

when comes install docker on centos, found 2 different ways it. the first 1 : yum install docker-engine the second 1 is: yum install docker-io and in case installed docker using first one, continue second 1 error appeared, this: error: docker-engine conflicts docker-1.8.2-10.el7.centos.x86_64 error: docker-engine-selinux conflicts docker-selinux-1.8.2-10.el7.centos.x86_64 so can tell me what's difference between them? this dates from june 2015 , when docker announced "new apt , yum repos" that when new packages ( like 1 centos ) named docker-engine (initially replace lxc-docker* )

(clang , msvc not allow this in static context). i absolutely prefer standard conform solution special solution

so far have learnt rewriterule ^([^/]*)/$ index.php?page=$1 problem 1: how parse url parameters after point point? e.g. want page http://example.com/index.php?page=x&id=2&err=10 appear http://example.com/x/?id=2&err=10 . given parameters id or err not exists. may or may not present others. problem 2: specific pages suppose page=a or page=b , if id exists, there third parameter well. e.g. want page http://example.com/index.php?page=a&id=10&name=abe appear http://example.com/a/abe/10/ , http://example.com/index.php?page=a&id=10&name=abe&err=101 appear http://example.com/a/abe/10/?err=101 edit 30 jan, 16 ok. after searching found implemented using {query_string} . when place rewriterule ^([^/]*)$ index.php?page=$1&%{query_string} [nc,l] in htaccess ajax goes haywire. want working implement index.php , no other pages. url rewrite parameters using rewritecond rule able solve problem 1, however, yet implement problem 2.

what efficient data structures matching data? example, suppose presented follow scenario: <time available> <buy or sell> <company name> <buy or sell price> <amount buy or sell> so file may contain: 0 sell yahoo $100 #1 2 sell yahoo $14 #1 2 sell yahoo $28 #1 .. 95 other yahoo sells <$125 , amount #1 3 sell yahoo $17 #1 5 sell yahoo $33 #1 9 buy yahoo $125 #100 is possible match last buy previous 100 sells in o(n) time, n = 100 if buy matched lowest selling price corresponding company wants buy (or 1 comes first in case of tie)? i know naive solution sort list , go in order, takes longer o(n) time. efficient data structures handling problem , similar ones it? try using hash map company name heap of sell orders, ranked price. insertion of sell order o(log n) , buy order becomes constant if buy doesn't use sell order, or o(log n) if (your problem statement doesn't specify)

in order create component, created designtime , runtime packages, runtime package (lets call rp140) contains code of component , requires rtl.dcp, designtime package (lets call dclrp140) contains register procedure , requires designide, runtime package , rtl.dcp. need access private variables declared in unit belongs "dclrp140" package, unit belongs "rp140", created simple code contains relevant part, make easier understand: unit mycomponentregister; interface uses classes, mycomponent; type tevent = procedure(sender: tobject) of object; tmycomponent = class(tcomponent) private fmyproperty: string; fmyevent: tevent; public constructor create(aowner: tcomponent); override; published property myproperty: string read fmyproperty write fmyproperty default initial_value; property myevent: tevent read fmyevent write fmyevent; end; procedure register; implementation procedure register; begin registercomponents('samp

so have big <div> block text in it. , word user double-clicks on wrapping in <span> element how can delete span element , return word it's normal place, w/o span wrapping it, whole text return starting position? edit: sorry absence. here's code of double-click function wraps div, user have double clicked on in span , adds class span. looking that! function ondoubleclick(){ var selection=window.getselection().getrangeat(0); var selectedtext=selection.extractcontents(); var span=document.createelement("span"); epic.get(span).addclass('highlightedtext'); span.appendchild(selectedtext); selection.insertnode(span); } this might want, expect evil 'regex in html'-links in comments :p. it's dependent on fact if <div> has text , spans in or many other (sub)children dom-nodes. var html = $('#mydiv').html(); var new_html = html.replace(new regexp('<span>[uu]ser</span>&

my chrome extension follows: $(document).ready(function() { ... $("input[type!='password'], textarea").on("keypress", function (event) { ... }); }); this reacts expected loaded content not work inputs or textareas loaded later. i though on supposed do, using wrong? i've played around try solve no success $(doocument).on("keypress", "input[type!='password'], textarea".... here live example in jsfiddle , first input works expected, generated ones don't. $(document).on("keypress", "input[type!='password'], textarea", function (event) { alert("this works!"); }); the listener being attached document , , keypress events checked against input[type!='password'] , textarea . if html markup structured in way there 1 parent container of input[type!='password'] , textarea , replace $(document) $('.parent-container') a
