i have read build tree flat array in php , convert series of parent-child relationships hierarchical tree? not figure out how implement problem. there pairs of relations such: array ( [0] => catalog.iden = catalog_sub.parent [1] => catalog.group = catalog_group.iden [2] => catalog_photo.iiden = catalog.iden ) i have not null, or 0, or explicit condition stop looping. know field has primary key auto_increment attribute. in example field named 'iden' in relation "parent". i have spent week resolve problem no result. me arrange array in order of relations. may tree of flat array. thanks in advance. update so far managed so: foreach($matches[0] &$match) { $ref = explode('=', $match); // split = sign $lft = explode('.', $ref[0]); $rgt = explode('.', $ref[1]); if($lft[1] == 'iden') { $arr[$lft[0]][$rgt[0]] = $rgt[1]; } else { $arr[$rgt[0]][$lft[0]] = $lft[1]; ...

extensible records provided http://hackage.haskell.org/package/vinyl different other libraries (hlist , others grapefruit-records/records) provide. because result of lookup based on pair (result type, label) , while other libraries have lookup based on label only. example of happening vinyl: {-# language datakinds, typeoperators #-} import data.vinyl r = fixrecord $ (field :: "x" ::: a) =: (3::double) <+> (field :: "x" ::: a) =: (2::int) main = print $ rget (field :: "x" ::: int) r print $ rget (field :: "x" ::: double) r -- prints 2\n3 for application http://hackage.haskell.org/package/rlang-qq , type of elements of record determined usage later on, seems need "x" uniquely determine value that's stored there. i want avoid "redundant" type signature in expression (rget (field :: "z" ::: [double]) (ans :: plainrec ("z" ::: [double] ': '[]))) and have more...

i'm newish linqtosql , project working on cannot changed else. translating old sql code linq. not being hot @ linq, used linqer translation me. query took 90 seconds run, thought must linqtosql. however, when copied query linqtosql produced , ran executequery on datacontext super quick expected. i've copied full queries, rather trying distil down, looks issue linqtosql doing behind scenes. to summarise, if copy t-sql created linq , run var results = db.executequery<invoicebalancecheckdto.invoicebalancecheck>(@"t-sql created linq - see below").tolist() it completes expected results in 0.5 seconds. runs same time directly in ssms. however, if use linqtosql code creates t-sql , tolist() takes ages. result 9 records, although without constraint check balance <> 0, there around 19,000 records. it's if it's getting 19,000 , checking <> 0 after it's got records. have changed linq project class used above, rather anonymous type, makes n...

when ever postback page blanked, have seen pages, page not being blank while post back can give me idea how can done thank you private void page_load() { if (ispostback) { // postback } else { // not postback } } refer link http://msdn.microsoft.com/en-us/library/system.web.ui.page.ispostback.aspx

i have custom listview has 2 textviews , 1 imageview in it. uses custom arrayadapter it's adapter, , wanted add search function it. i've looked through every single tutorial find, no luck. 1 tutorial able search through regular listview (not using custom adapter), not work me because need show both textviews , imageview. need filter 1 of textviews though, don't see how trouble be. anyway, here mainactivity: public class itemid extends activity { // list view private listview lv; // listview adapter arrayadapter<string> adapter; // search edittext edittext inputsearch; // arraylist listview arraylist<hashmap<string, string>> productlist; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.testo); context ctx = getapplication(); resources res = ctx.getresources(); string[] options = res.getstringa...

i have 2 auto-generated classes generated xsd tool. the classes have same name , similar member variables. but many of members different. i storing these classes in different folders. there still conflict - this the type 'response' contains definition 'field1' how store these classes avoid conflict?? i don't want change in classes auto-generated , changing them might cause xml parsing errors the classes have structure below:- public partial class response { public string field1; public string field2; public string field3; } public partial class response { public string field1; public string field2; public string field4; } the classes stored follows myproject->classes->folder1->class1 myproject->classes->folder2->class2 if entire class autogenerated visual studio (and not touched/moved afterwards), classes have different namespaces namespaces derived folder names. different namespaces shouldn't have ...

the old version of opencv returned number of neighbors detected, , used measure of confidence. for example: cv.haardetectobjects(grayscale, cascade, storage, 1.2, 2, cv.cv_haar_do_canny_pruning, (50,50)) [((174, 54, 114, 114), 53)] the new version of opencv changed signature used, either detectmultiscale(image[, scalefactor[, minneighbors[, flags[, minsize[, maxsize]]]]]) -> objects or detectmultiscale(image, rejectlevels, levelweights[, scalefactor[, minneighbors[, flags[, minsize[, maxsize[, outputrejectlevels]]]]]]) -> objects the second signature has rejectlevels , levelweights which, understanding, can used confidence. this reflection of c++ version of functions. but, unclear me how pass parameters changed in python. i've tried, example, following, not change r , w : r = list() w = list() res = cascade2.detectmultiscale(image=img, rejectlevels=r, levelweights=w) print res print r, w [[ 82 158 53 53] [175 157 52 52] [103 266 112 112]] ...
