i may have confused implementation of database asp.net mvc project, have separate data layer connection string pointed .mdf file. i imported data models through ado.net entity data model code-first existing database. when go enable migrations, no problem. however, i'm trying add-migration , , get: unable generate explicit migration because following explicit migrations pending: [201504081848445_initialcreate]. i checked server explorer, , noticed have both "databasecontext" , database.mdf showing up. sorry if elementary question, suspicion has connection string? saw when first enable , create migrations, show in databasecontext . next day, see "databasecontext" missing _migrationhistory , , see error message explicit migrations pending. my connection string: <connectionstrings> <add name="databasecontext" connectionstring="data source=(localdb)\v11.0;attachdbfilename=|datadirectory|\database.mdf;int

i trying output array of 10-element arrays containing permutations of 1 , 2, e.g.: [[1,1,1,1,1,1,1,1,1,1], [1,1,1,1,1,1,1,1,1,2], [1,2,1,2,1,2,1,2,1,2], ...etc... [2,2,2,2,2,2,2,2,2,2]] i have done smaller arrays, (10): = [1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2] = a.permutation(10).to_a print a.uniq ...this apparently big calculation- after hour running, hadn't completed , ruby process sitting on 12gb of memory. there way come @ this? first, check size of permutation a.permutation(10).size => 670442572800 it's huge. can instead use array#repeated_permutations on smaller array. check here: b = [1, 2] # unique elements b.repeated_permutation(10) # returns enumerable b.repeated_permutation(10).to_a # creates array of permutations those permutations unique (which u can check printing size , without array#uniq )

i want value of 2nd <td> <tr> <td>devaraj</td> <td>shiva</td> </tr> result expected : 'shiva' how can search 1st <td> tag value , take value of 2nd <td> tag value? thanks you use document.queryselector() which: returns first element within document (using depth-first pre-order traversal of document's nodes) matches specified group of selectors. so target 2nd td : document.queryselector('table td:nth-child(2)') see jsfiddle or following snippet alert(document.queryselector('table td:nth-child(2)').innerhtml) <table> <tr> <td>devaraj</td> <td>shiva</td> </tr> <table>

css flexbox newbie here. i'm trying achieve layout with a fixed-height header a content area takes available space, , displays image. a fixed-height footer i got working following flexbox code: <html style="height: 100%;"> <body style="height: 100%;"> <div style="display: flex; flex-direction: column; height: 100%;"> <div style="background-color: rgba(255, 0, 0, .1)";> header </div> <div style="flex: 1; background-color: gray;"> content </div> <div style="background-color: rgba(0, 0, 255, .1)"> footer </div> </div> </body> </html> this works great. want display image inside of content area. small images, works fine: <!-- inside content div

heloo guys... once try run code gettin 'invalid pointer operation' error, problem ? supposed sort names in textfile alphabetical order (school project). program project2; {$apptype console} uses sysutils, classes; var names : textfile; count : integer=0; array : array of string; : integer; procedure load; begin reset(names); setlength(array, count - 1); := 1 count readln(names, array[i]); end; begin assignfile(names, 'names.txt'); reset(names); while not eof(names) begin readln(names); inc(count); end; load; := 1 count writeln(array[i]); readln; closefile(names); erase(names); end. dynamic arrays zero-based. need set length count , iterate 0 count-1 . setlength(arr, count); := 0 count-1 readln(names, arr[i]); obviously indexing needs changed 0-based. i changed name of array arr because array keyword. do not attempt continue 1-based indexing. doing cause endless headaches.

i'm using lua create "plug-in" linux-based operating system. program contains c function recursive 1 (not intended is). @ moment, each time function called provides result 4-5 times. i'd ask question concerning recursive function(s) , results. possible take multiple (same) results of recursive function , use 1 of set(s) of results? example: (i'm going state "os function" point out coded operating system i'm integrating lua into) function abc123() -- os function based in os local names = os_names() -- os function local index, var = os_rows() -- os function pull vars file k,v in pairs(names) index2, var2 = os_rows(k) -- os function pull vars file if var2 ~= var os_rows(k,var2,var) -- recursive os function cnt = 1 while cnt <= 4 data_tbl = file_info(x,y,z) -- personal function grab info , return table info_tbl[data_tbl.id]=data_tbl

i overloaded case class's equality operator: case class polygon(points: seq[(double, double)]) extends shape { def ==(that: polygon): boolean = { ... } } my unit tests pass when using double-equals in assertions: import org.scalatest.funspec class shapespec extends funspec { describe("polygon") { it("is equal rotations") { val p = polygon(seq( ... )) { ← 0 until p.points.size } { val q = polygon(p.points.drop(i) ++ p.points.take(i)) assert(p == q) } } } } but when using === instead of ==, same tests fail: [info] polygon [info] - equal rotations *** failed *** [info] polygon(list((-1.0,-1.0), (4.0,-1.0), (4.0,2.0), (1.0,2.0), (1.0,1.0), (-1.0,1.0))) did not equal polygonm(list((4.0,-1.0), (4.0,2.0), (1.0,2.0), (1.0,1.0), (-1.0,1.0), (-1.0,-1.0))) (shapespec.scala:28) why happen? you spelled wrong. ;) it should be: override def equals(x: any): boolean

is possible f# have function composition between operators.not , standard .net function, instance string.isnullorempty ? in other words, why following lambda expression unacceptable: (fun x -> not >> string.isnullorempty) the >> function composition works other way round - passes result of function on left function on right - snippet passing bool isnullorempty , type error. following works: (fun x -> string.isnullorempty >> not) or can use reversed function composition (but think >> preferred in f#): (fun x -> not << string.isnullorempty) aside, snippet creating function of type 'a -> string -> bool , because ignoring argument x . suppose might want just: (string.isnullorempty >> not)

i have weird issue: have loop in javascript works absolutely expected in chrome not in firefox or ie. in firefox , ie adds undefined item array , have no clue why. angular.module('app', []) .controller('itemctrl', function($scope){ $scope.itemsa = [ { name: 'testa' }, { name: 'testb' } ]; $scope.itemsb = []; $scope.dosomething = function(idparam) { for(var = 0; < $scope.itemsb.length; i++){ if ($scope.itemsb[i].name === $scope.itemsa[idparam].name) { ... }; }; according developer tools in both browsers $scope.itemb has length 0 @ loop start line for(var = 0; < $scope.itemsb.length; i++) (for whatever reason) still starts loop (which shouldn't know) , in following line if ($scope.itemsb[i].name === $scope.itemsa[idparam].name) there appears undefined item 0 array position out of (and produces error of course). any ideas?

this possibly stupid question, i'm trying compose email message suggested here multipart/mixed multipart/alternative text/html text/plain attachment 1 attachment 2 so i'm having mimemultipart altpart = new mimemultipart("alternative"); bodypart textpart = new mimebodypart(); textpart.setcontent("sometext", "text/plain"); altpart.addbodypart(textpart); bodypart htmlpart = new mimebodypart(); htmlpart.setcontent("somehtml", "text/html"); altpart.addbodypart(htmlpart); mimemultipart mixedpart = new mimemultipart("multipart/mixed"); and need add altpart mixedpart , can't adding method accepts bodypart only. wtf? note unlike here , i'm not mixing packages. you need wrap mimemultipart in mimebodypart , using mimebodypart.setcontent(multipart mp) method. can add mimebodypart mixedpart object: mimemultipart alternativemultipart = new mimemultipart("alternative");

this question has answer here: why , how rand() exist both in global , std namespace in cstdlib? 2 answers getenv() has c++ implementation can included in header file . member of namespace std. however, getenv() function can resolved correctly in code without std::getenv(), means follow program can compiled , run without error , warning. why getenv() name member of namespace std can resolved without std::? os , compiler ubuntu 12.04 i386 , g++ 4.8.1 respectively. #include <cstdlib> #include <iostream> int main() { char * path_env; path_env = getenv("path"); //without name resolve operation std::getenv() std::cout << path_env << std::endl; return 0; } try use search before asking questions. duplicate of why , how rand() exist both in global , std namespace in cstdlib? c++11 standard: d.5 c standard lib
