i have 2 projects qt-creator c++. let's call project , project b. project works fine. project b strange. last week when tried debug it, stuck. re-saved .pro file (not changing anything) , works. every time build , debug (which build , run ), qt rebuild all. creates moc_blabla.o again every time build it. when debug project b, qt rebuild , run, not build , run. in project works fine. project a.pro , project b.pro have same architecture, no special configuration, default. there wrong did in project b? there way can normal build in project b again? qt creator gets things mixed up, instance, when have hand-edited project file. if project acts strangely close projects , editors in qt creator , delete intermediate files (*.obj, .o, ...) , outputs ( .exe, *.dll, *.lib, *.dylib, ...) produced project. also, delete .pro.user file(s). last step force qt creator configure project anew (and create new .pro.user file). all of above might achieved through make clean or qt cre

i have 2 tables called yl0pf (which master or parent record) , yl1pf (which detail or child record). they join yl0ab=yl1ab, yl0an=yl1an, yl0as=yl1as and restrict records column dteinp. there can 0 many detail records 1 master record. child records arrears records showing months payments have been missed month due so can of course this: select y0.* , y1.* alpsproduction..yl0pf y0 left outer join alpsproduction..yl1pf y1 on y0.l0ab = y1.l1ab , y0.l0an = y1.l1an , y0.l0as = y1.l1as y0.dteinp = '01 jun 2015' order y0.l0ab + y0.l0an + y0.l0as , y1.l1ab + y1.l1an + y1.l1as , cast(y1.dteinp date) desc and put child records next repeating parent records. but if possible extract data below: l0as1, l0an1, l0as1, * l1as1, l1an1, l1as1, * l1as1, l1an1, l1as1, * l0as2, l0an2, l0as2, * l

example: template <typename t> class bar { public: void foo(t&& arg) { std::forward<t>(arg); } }; bar<int> bar; bar.foo(10); // works int a{ 10 }; bar.foo(a); // error c2664: cannot convert argument 1 'int' 'int &&' it seems universal references works only templated functions , only type deduction, right? make no sense use class? , using of std::forward makes sense in case? note preferred terminology (i.e. 1 in future versions of spec) forwarding reference . as say, forwarding reference works type deduction in function template. in case, when t&& , t int . can't int& because has been explicitly stated in bar instantiation. such, reference-collapsing rules can't occur, can't perfect forwarding. if want perfect forwarding in member function that, need have member function template: template <typename u> void foo(u&& arg) { std::forward<u&g

suppose have data object uploaded user: data <- reactive({ infile <- input$file if (is.null(infile)) return(null) data <- read.csv(infile$datapath) return(data) }) and suppose want delete columns in dataset. want set global assignment can run ui multiple times , have each effect saved in object. dataset <- reactive({ file1 <- data() file1[,input$deletecols] <<- null return(file1) }} }) however, when run this, error: invalid (null) left side of assignment what's causing error? , how can achieve effect if global assignment doesn't work? thanks much. you should use reactivevalues() kind of need, because allows create , modify data @ different stages in app. here example (not tested): values <- reactivevalues() observe({ infile <- input$file if (!(is.null(infile))){ values$data <- read.csv(infile$datapath) } }) observe({ values$data[,input$deletecols] <- null }

i'm writing app common lisp uses opengl, , thing has grown i've realized have bit of choice make. have bunch of different classes need code render them , often, i'm considering following code structures doing this: (defgeneric render (x)) (defmethod render ((x vanilla-foo)) (generic-foo-stuff) (vanilla-specific-stuff) (more-generic-foo-stuff)) (defmethod render ((x chocolate-foo)) (generic-foo-stuff) (chocolate-specific-stuff) (more-generic-foo-stuff)) and on, lots of these methods. other alternative use typecase statement: (defun render (any-old-foo) (generic-foo-stuff) (typecase (vanilla-foo (vanilla-specific-stuff)) (chocolate-foo (chocolate-specific-stuff)) ;;and on, lots of cases here ) (more-generic-foo-stuff)) i suppose these both ugly in own way, assumption lisp using kind of hash table o(1) lookup under hood maps argument type passed generic function location of needed method, whereas
