i have base class has large number of derived classes, , base class has several constructors. in derived classes have implement empty constructors forward arguments base constructors. possible somehow tell c# use derived constructors? for example, if using base class. class basetool { public basetool(string arg1, string arg2) { // stuff. } public basetool(string arg1) { // stuff. } public basetool(int arg1) { // stuff. } } i have implement above constructors arguments, , call : base(...) forward them derived class. resulting in lot of classes have empty constructors. seems lot of wasted code. constructors not inherited base classes, there no way around declaring constructors in each derived class. however, automate repetitive task with, example, t4 templates .

sorry if blatantly obvious issue resolution. can't seem figure out how fix it. i'm importing. import android.provider.settings; and attempting run code snippet below in activities, application, broadcast receivers, etc. works fine in paid version of app. when copy code out free version , paste in(same machine, same sdk) compiler goes red. boolean candrawoverlays; if(build.version.sdk_int >= 23) { candrawoverlays = settings.candrawoverlays(getapplicationcontext()); } solved. blatantly obvious. save time , trouble in future of overlooked project setting. right click project. goto module settings. goto compile sdk version. set api level appropriate. in case @ level 19 , needed 23 candrawoverlays coming through. alternatively open project's build.gradle , set compilesdkversion there.

i wondering if there simple way copy either entire oracle database table or data rows oracle database table (different databases). there type of way using sql language? initial thought use sql query this: insert outputtable select * username/password@instance.inputtable if not sql, there way this? trying automate task performing copy using sql developer or along lines not suffice unfortunately. trying using python. you can create dblink connect source , target db, use sql save data in linked db. something like: create database link "target" connect your_schema identified your_password using your_connection_string; once have dblink, can use plain sql, no matter involved tables on different db: insert your_table@target select * your_table

i have been using eclipse quite time, have used c++ programming. bunch of fun figuring out how actual compile c++ on eclipse on system, have figured out 100% success, have stumbled upon annoying issue. have seen if create class in header file can use nifty tool under source menu called "implement method" take function declarations header file , place them in source file body ready code. well today messing around new code , needed template class working on, behold when tried use implement method function find eclipse tells me there "no implement file found 1 or more methods" , instead creates inline function in header file (like need that!). bug in eclipse or there underlying c++ rule cannot avoided? dont seem understand why having class declration class foo{}; work fine, having template <typename t> class foo{}; causes error. know issue becuase if declare normal class 1 public function works, if take same class , declare template class find error occur

suppose have binary stream stream , generate follows. stream.write('lol'.encode()) yaml.dump(some_obj, stream) stream.write('awesome'.encode()) then have write custom parser of sort stream or can recover some_obj follows. stream.read(3) recovered = yaml.load(stream) stream.read(7) if doesn't work yaml serialization, work json serialization? you cannot want because yaml parser consumes complete stream if dummp explicit end ( yaml.dump(some_obj, stream, explicit_end=true) (which insert ...\n before awesome ) , doesn't work when writing ---\nawesome (the document separator). yaml parser consumes word awesome ¹ both when use yaml.load() when use yaml.load_all() . the part front works fine, can consider doing like: import ruamel.yaml yaml file_name = 'test.comb' some_obj = dict(a = [1, 2], b = {3: 42}) open(file_name, 'w') stream: stream.write('lol'.encode()) yaml.dump(some_obj, stream, explicit_end=tr

consider following: string const& name1 = get_name(...); string const name2 = get_name(...); where get_name returns string object. known, introduction of move-semantics in c++11, both statements can efficient, first 1 being more since move not need made. (yeah, know return-value optimization, it's more nuanced. general idea.) however, suppose function calls left out of this: string const& name3 {"billy"}; string const name4 {"debbie"}; in case, string-literal "billy" implicitly converted temporary string , , name3 binds temporary. obviously, name4 not temporary. is true name3 , name4 , both equally efficient? seems me be... name3 , name4 indistinguishable rest of program, unless use decltype(name3) or decltype(name4) . so compiler can generate same assembly both cases. of course, general statement; individual compiler may generate slower or faster code , way find out try on compiler.
