wonder if can help; i have 2 dimensional array need group common "job number" element; here's example - i'm playing idea @ moment, $i counter iterates through array results; $galleryitems[$i][0] = 'example title';//the title $galleryitems[$i][1] = 'example description';//description $galleryitems[$i][2] = 'the client';//client $galleryitems[$i][3] = '00000';//job number any ideas on how group these toegther, eg if had number of 00000 job items stick these toegther, , 00001 group etc. thanks $galleryitemsgrouped = array(); foreach($galleryitems $k => $v) { $galleryitemsgrouped[$v[3]][] = $v; } var_dump($galleryitemsgrouped); or maybe that's mean usort($galleryitems, function($a,$b) { if($a[3] == $b[3]) return 0; return $a[3]<$b[3] ? -1 : 1; }); var_dump($galleryitems);

in c#, after add object collection, if copy(deep copy) created? no, if class, objects are, reference same object stored in collection. if value type, int, double , structs copy made (not deep copy, if struct has reference class object in turn not copied). edit: deep copy objects first need create deep copy function. have @ create deep copy in c# or how make deep copy in c# ? can run deep copy method before adding items collection. note not need true deep copy. better rethink dataflow in application.

i have in code: double** desc = new double* [size_out]; (int = 0; < size_out; i++) desc[i] = new double [size_in]; how delete desc ? should do: delete [] desc; or for (int i=0; i<size_out; i++) delete [] desc[i]; delete [] desc; or for (int i=0; i<size_out; i++) delete [] desc[i]; delete desc; ? simple rules follow: for each allocation, there has deallocation (ex1 therefore wrong) what allocated using new should freed using delete , using new[] should deallocated using delete[] , using malloc should deallocated using free (ex3 therefore wrong) conclusion, ex2 ok.
