i have database few columns login screen, trying compare entered email persons password in database. i have following code, although keep getting error saying column email not exist, although in database. ideas? public string getplayerpassword(string emailparameter) throws sqlexception { loadsqldriver(); string playersemail = null; prestmt = con.preparestatement("select playerpassword players email = ?"); prestmt.setstring(1, emailparameter); rs = prestmt.executequery(); if(rs.next()){ playersemail = rs.getstring("email"); } return playersemail; } this may because dint select email in query prestmt = con.preparestatement("select playerpassword players email = ?"); and fetching it playersemail = rs.getstring("email");

at beggining, sorry title of question - not came better one. suggestions welcome. i wrote __init__ method class, works great, looks ugly. can improved? mean duplicate line calling function super() . def __init__(self, *args, **kwargs): """ creates selenium driver. :param args: non-keyword variables passed selenium driver. :param kwargs: keyword variables passed selenium driver.

how negate boolean function? such using like: _.filter = function(collection, test) { var tmp = [] _.each(collection, function(value){ if (test(value)) { tmp.push(value); } }) return tmp }; var bag = [1,2,3]; var evens = function(v) { return v % 2 === 0}; this wrong: // returns opposite of evens var result = _.filter(bag, !evens); result: [1,3] try making function returns function: function negate(other) { return function(v) {return !other(v)}; }; used this: var result = _.filter(bag, negate(evens)); or declare function when call it: var result = _.filter(bag, function(v) {return evens(v)});

i'm newbie both in soap , rest programming. in soap structure , fields of entities being exchanged , unambiguously documented in wsdl . i think same not happen in rest . how developer of rest api supposed document structure , fields of json objects, representing entities being exchanged? rest , soap can't compared directly, different things. can implement rest on soap if want, not opposite. recommend reading this answer . in restful apis supposed document media-types , let interaction driven underlying protocol, don't in of http apis call rest. using term buzzword , opposite of that, documenting protocol instead of media-types. for instance, if have user resource, supposed have proper media-type in format json or xml looks application/vnd.mycompany.user.v1+json , , documentation should describe json document looks client knows expect. doesn't have strict wsdl. in fact, can human readable documentation documenting class api or that. the cl

i using qgraphicsscene draw millions of polygons. plan use qt+opengl later, not drawing more 1 million polygons , qt handles fine. problem arises when try display text inside polygons. each polygon (a custom class inheriting qgraphicspolygonitem) visual representation of object, , has pointer object associated it. each object has std::string identifier. if display that string inside polygons, should fine memory-wise. however, qt seems need qstring instead, , takes lot of time , space convert every string. creating qgraphicstextobject each polygon , each of needs qstring copy of std::string . there way bypass copy using qt? cropping scene not desirable. there polygons small text fit inside them, , 1 can see them zooming in scene. these polygons (and text) need not displayed (unless user zooms in), don't think without creating various other issues first. p.s.: displaying text on-demand (as user hovers mouse on each polygon, instance) possible, it'd ideal if text rea

we have c++ program which, depending on way user configures it, may cpu bound or io bound. purpose of loose coupling program configuration, i'd have thread pool automatically realize when program benefit more threads (i.e. cpu bound). nice if realized when i/o bound , reduced number of workers, bonus (i.e. i'd happy automatically grows without automatic shrinkage). we use boost if there's there can use it. realize solution platform specific, we're interested in windows , linux, tertiary interest in os x or other *nix. short answer: use distinct fixed-size thread pools cpu intensive operations , ios. in addition pool sizes, further regulation of number of active threads done bounded-buffer (producer/consumer) synchronizes computer , io steps of workflow. for compute- , data-intensive problems bottlenecks moving target between different resources (e.g. cpu vs io), can useful make clear distinction between thread , thread, particularly, first approximation

this question has answer here: double pointer const-correctness warnings in c 2 answers why is: int *a = 0; int const *b = a; /* totally fine. */ int **c = 0; int const **d = c; /* generates nasty warning. */ shouldn't okay implicitly cast more const type? is there way work around it? have following array: int **a; and want call following functions without ugly explicit cast: void foo1(int const **a); void foo2(int const * const *a); it's complicated. the reason cannot assign char ** value const char ** pointer obscure. given const qualifier exists @ all, compiler keep promises not modify const values. that's why can assign char * const char *, not other way around: it's safe ``add'' const-ness simple pointer, dangerous take away. however, suppose performed following more complicated series of assignments: const

i trying verify floats ("data" attribute) find in descending order. here have far: list = self.driver.find_elements(by.css_selector, "locator") in list: data = i.get_attribute("data") should doing in loop? i'm pretty new webdriver , coding in general. thanks! don't use variable name list it's python keyword. if data indeed attribute of i can do: for in my_list: data = i.data or more usefully, like: data = [] in my_list: data.append(i.data) or shorter: data = [i.data in my_list] you can check descending order comparing data sorted version of itself: print 'data in descending order:', data == sorted(data, reverse = true)
