i've been changing foreground color of progressbar control c# code using brush , brushes classes system.windows.media library. however, i'm wondering if .net provides access original default foreground color of progressbar when want revert back. example: right i'm referencing answer provided @beauty on this question uses systemcolors class. systemcolors seems .net class provides default brush colors of controls, don't see brush foreground of progressbar . color obtainable in systemcolors , or there other way of getting it? an example of how changing colors: xaml: <progressbar name="progress" foreground="{binding loadscreenmodel.barcolor}" /> c#: private brush _barcolor = brushes.red; public brush barcolor { { return _barcolor; } set { _barcolor = value; notifypropertychange(() => barcolor); } } the default style progressbar control (found on question , can on msdn ) reve

we have table (t) ~3 million rows , 2 int columns (id1 , id2), set composite clustered key. early in stored procedure create table variable (@a) consists of list of ints. the slow query following select t.id1, t.id2 t inner join @a on a.id = t.id1 @a have few hundred rows, , t contains few million rows. problem t gets scan count of several hundred. don't know how make go away. i have tried create index on t column id1 , id2 included, not (the execution planner shows new index used). what can done reduce scan count on table t? (we using sql server 2014, web edition) try creating included (covering index): create index idx_t_id1 on t(id1) include id2 this allow query find needs in index pages , not have search in main table. way there clustered index on table t?

this question has answer here: function override-overload in java 6 answers i trying understand overloading @ moment , bit confused. understand when calling same method, cannot have exact same arguments. instance method called 2 int variables , 2 different int variables. if use int , float, okay. know return type not matter, being public or private method. matter? for instance, call public int name(int x) able call private int name(int x) ? am correct in assuming public double name(string x) cause overloading in class? public int name(int x, string y) valid? passing string argument int function? cause overloading or error? edit: not believe question duplicate, main question difference between public , private, method or different , cause overloading. did not see addressed in other question. from oracle tutorial : overloaded methods differentiat

i need present data 2 tables in same view. when use calculated property performance penalty not acceptable. if have done using sql possible using join. know how using linq , entity framework. the problem lightswitch lets me execute queries results in list of existing entities. i'm creating desktop client. if correct relationships have been set up, possible data items multiple entities displayed concurrently solely using built in queries. question doesn't have enough detail know whether work here, it's best way go if can keep benefit of other automagical lightswitch features. if it's not possible using built in queries or want change shape of data , not return lightswitch entities, use wcf-ria service. sounds approach here leverage linq knowledge too. http://lightswitchhelpwebsite.com/blog/tabid/61/entryid/2226/creating-a-wcf-ria-service-for-visual-studio-2013.aspx covers how in vs2013. it's 1 of things sounds complicated @ first ok if follow

so using laravel , running issue, have relational model adsale, have setup hasone relationship adimpressions. example grab adsale records userid = 1. 5 different rows back, each of 5 rows have 5 adimpression rows match , have info clicks , impressions. end goal adimpression rows. when run has 1 impressions() method undefined method. if foreach on adsale records individually , run impresssions() method works. here code class adsale extends eloquent{ protected $table = 'adsale'; public function impressions() { return $this->hasone('adimpression','adsaleid','id'); } } here connecting adsale respective adimpression via adsaleid in adimpression table. this running in controller. $sales= adsale::where('userid','=', 1)->get(); $impressions = $sales->impressions(); now expect $impressions variable have adimpressions entry correlates adsaleid, getting undefined function since there multiple val

my intro computer science teacher gave dice guessing game challenge, , while i've managed figure out of components, final piece return correct number (once they've guessed it) , number of tries took them figure out. code returns of that, doesn't account if person guessing guesses same number twice. there way tell them how many guesses took them find number while disregarding repeated numbers? this code have far: import random give_number = input("we roll 6 sided dice. think number be?\n ") guess_number = 1 dice = random.randint(1,6) while give_number != dice: if give_number > dice: give_number = input("sorry, answer high! try again!\n ") guess_number = guess_number +1 if give_number < dice: give_number = input("sorry, answer low! try again!\n ") guess_number = guess_number +1 print "congratulations, right, answer {}! took {} tries.".format(dice, guess_number) to detect

i new java programmer , working on project requires me read text file has movie reviews. once i've read file, asked search , sort through array of movies , return total number of reviews each movie average rate each movie. the portion stuck on iterating through array list. i using inner , outer loop , seem getting infinite loop. i appreciate second set of eyes. have been staring @ project few days , starting not see mistakes. here code: import java.io.*; import java.util.*; import java.lang.*; public class moviereviewapp { public static void main(string[] args) { string strline = ""; string[] result = null; final string delimit = "\\s+\\|\\s+"; string title =""; //int rating = (integer.valueof(- 1)); arraylist<moviereview> movies = new arraylist<moviereview>(); //arraylist<string> titles = new arraylist<string>(); //arraylist<integer> ratings = new arraylist<integer>

i've class method below creates local object , calls method on local object. public class myclass { public somereturn mymethod(){ myotherclass otherclassobject = new myotherclass(); boolean retbool = otherclassobject.otherclassmethod(); if(retbool){ // } } } public class myclasstest { @test public testmymethod(){ myclass myclassobj = new myclass(); myclassobj.mymethod(); // please me here.. } } when i'm testing mymethod , want mock otherclassobject.otherclassmethod return of choice. otherclassmethod class message queues , don't want in unit test. want return true when otherclassobj.otherclassmethod(). know must have used factory myotherclass instantiation in case it's legacy code , don't want change code now. see mockito doesn't provide facility mock myotherclass in case possible powermockito. however, not find example above scenario found static class. how shoul

i'm writing console application in qtc, , has lot of "cout << " outputs of project configurations unit tests (catch utest framework) , nothing of has shown in application output window. on projects tab - run in console has been switched off. , don't plan use qdebug() because project doesn't use qt library how can fixed? output cout should not in application output, should in separate console window console projects (if have config += console in pro file). make sure have system("pause"); at end of program able see console window, can closed before can see output.

i'm programming server-client program. on server manage clients through array of data structure: struct client { struct sockaddr_in addr; /*...*/ }; struct client clients[max_cli]; when receive first packet client through udp socket struct sockaddr_in addr_cli; memset(&addr_cli,0,sizeof(struct sockaddr_in)); b=recvfrom(sock_udp_father, &pdu, sizeof(pdu), msg_dontwait, (struct sockaddr *)&addr_cli, (socklen_t *)&laddr_cli); i want copy address struct. do: memcpy(&clients[client].addr,(struct sockaddr*)&addr_cli, sizeof(struct sockaddr_in)); printf("ip client: %s",inet_ntoa(clients[client].addr.sin_addr); the strange thing first try of communication fails, printing 0.0.0.0 . next try client does, successful , goes fine. why happens? the addr_cli not filled call recvfrom . last 2 arguments of recvfrom little bit tricky. are struct sockaddr *src_addr, socklen_t *addrlen if src_addr not null, recvfrom

i have posted web service client. going through pci dss (i dont know is) , have had disable medium strength ssl sslv3. they asking if can modify service doesn't require ciphers. i don't know talking about. can give me direction? pci dss 3.0 requires mandate tls 1.2. ssl v3 removed organization not pci compliant if they're using ssl v3. pci dss compliance needed organization deals card related information ( credit card / debit card etc ). it's mandatory have pci dss compliance organizations. so basically, they're asking whether service can support tls 1.2 instead of older ciphers in ssl v3.
