(even tried true in case misunderstood attribute). furthermore tried other attributes without success. display(autogeneratefield = false) editorbrowsable(editorbrowsablestate.never) when create ria service, & attach data source, lightswitch treats entity/table, same of it's own entities. though lsmls file has "hidden" attributes applied properties, means "display default" checkbox has been unticked property in table designer. unticking box means in auto-generated screens property won't displayed. if create own screen, based on entity, screen designer omit adding properties visual tree. the way know of "hide" pro...

i have mysql table looks this: my_number my_unique_text_field in which, my_number integer whenever insert number field my_number , i'd unique text value assigned field my_unique_text_field . possible achieve using mysql directly? or must generate unique text string using client (i using python )? mysql's uuid enough. in case if still worry possible duplicates - you'd better generate in python , handle unique constraint error.

i'm building object tracking api team. my code recognize foreground objects in camera scene. on time, call methods addobject(id, pos) , updateobject(id, newpos) , , removeobject(id) on instances implement listener interface. these post frame-processing events -- might occur 30 times second. how can make sure objects don't flicker in , out of existence? need give objects minimum lifetime. if object disappears 1 frame , reappears in same spot in next frame new id, undesired flickering. (my thoughts far) have thought using object mask accumulator basis instantiation. imagine grayscale image, candidate regions objects intensified in accumulator each frame, object region exceeds threshold, gets instantiated , call addobject(id, pos) method. now, problem is, object can hover around threshold in accumulator , can still exhibit flickery behavior. then, add constant value object region instantiated have lifetime in accumulator. constant subtracted when region crosses bel...

following this question , i'm wondering why struct\class in c++ has have virtual method in order polymorphic. forcing virtual destructor makes sense, if there's no destructor @ all, why mandatory have virtual method? because type of polymorphic object in c++ is, basically, determined pointer vtable, table of virtual functions. vtable is, however, created if there's @ least 1 virtual method. why? because in c++, never didn't explicitly ask for. call "you don't have pay don't need". don't need polymorphism? saved vtable.

this question has answer here: *args , **kwargs? [duplicate] 11 answers is there syntax allows expand list arguments of function call? example: # trivial example function, not meant useful. def foo(x,y,z): return "%d, %d, %d" %(x,y,z) # list of values want pass foo. values = [1,2,3] # want this, , result "1, 2, 3": foo( values.howdoyouexpandme() ) it exists, it's hard search for. think people call " splat " operator. it's in documentation " unpacking argument lists ". you'd use this: foo(*values) . there's 1 dictionaries: d = {'a': 1, 'b': 2} def foo(a, b): pass foo(**d)

i've access table this id | username | carbrand ------------------------- 0 peter vw 1 peter ferrari 2 mike audi 3 peter dodge 4 heidi bmw 5 heidi ford i need names carbrand field comma separated list report. is there way (without vb, maybe using coalesce alternative?) create comma-separated string this, without name: part? peter: vw, ferrari, dodge mike: audi heidi: bmw, ford as it's report there other ways this, maybe using expressions in report? you cannot access without vba. coalesce not exist, can write udf has of functionality, example http://allenbrowne.com/func-concat.html however, once use udf, query no longer viable outside access.

i think i've seen issue before , bet there's better solution out there asking.. during debugging found printf before assert don't work well. they're not printed of time. tried adding fflush(stdout ) doesn't seem help. any other thoughts or alternatives? example: printf... <- not printed printf... <- not printed due assert. stdout not flushed? assert() call fflush(stdout) before assert . or, if stdout has not been redirected , refers terminal, writing newline @ end of message should sufficient. default, stdout buffered (line buffered on terminals; buffered otherwise) , output not written until output buffer overflows or newline (in line-buffered mode) or fflush encountered.

this question has answer here: developing android in eclipse: r.java not regenerating 63 answers recently android program won't generate auto-generated r.java file under gen in android project. tried doing project->clean , still doesn't work. restarted eclipse multiple times. any ideas? make sure don't have errors* under problems tab in eclipse. try use fix project properties under android tools when right click on project. if doesn't fix problem, try modifying androidmanifest.xml (just add space , save). i've heard force r.java rebuild. * except errors says r cannot resolved variable - these errors go away once correct other errors , force r.java rebuild.

i have db.model has db.userproperty. example: class photo( db.model ): owner = db.userproperty() title = db.stringproperty() when want photos user, this: photos = photo.gql( "where owner = user(:1)", users.get_current_user().nickname() ) this causing problems, however, between google , non-google nicknames. when testing locally, if use email address test@example.com, nickname "test@example.com". if use test@gmail.com, nickname "test". when test gmail account, have append "@gmail.com" .nickname(). is there better way hard-coding + "@gmail.com" database queries? photos = photo.gql("where owner = :1", users.get_current_user())

i use rvm in rails project , specify gem versions in gemfile. however, problem right different. want create rails 3.1 project using rails new project_name current version of rails rails 3.0.3 i know can update rails gem version future executions of rails new project_name create 3.1 project? how can set things can create rails 3.1 projects while other times creating rails 3.0 projects? rvm 1.9.2 rvm gemset create rails310 rails303 rvm 1.9.2@rails310 gem install rails -v 3.1.0 rails new my_310_app rvm 1.9.2@rails303 gem install rails -v 3.0.3 rails new my_303_app http://beginrescueend.com/gemsets/basics/

i understand how gcd works on trivial example below: for(i=1; i<=100; i++) { x[2*i+3] = x[2*i] + 50; } we first transform following form: x[a*i + b] , x[c*i + d] a=2 , b=3 , c=2 , d=0 , gcd(a,c)=2 , (d-b) -3 . since 2 not divide -3 , no dependence possible. but how can gcd test on doubly nested loop? for example: for (i=0; i<10; i++){ (j=0; j<10; j++){ a[1+2*i + 20*j] = a[2+20*i + 2*j); } } while subscripts can delinearized, gcd test simple apply directly. in example, subscript pair [1+2*i + 20*j] , [2+20*i + 2*j] , we're looking integer solution equation 1 + 2*i + 20*j = 2 + 20*i' + 2*j' rearranging, get 2*i - 20*i' + 20*j - 2*j = 1 compute gcd of coefficients, 2, -20, 20, , -2, , see if divides constant. in case, gcd 2. since 2 doesn't divide 1, there's no dependence.
