this example of sql query: declare cursora cursor select ida ... open cursora fetch next cursora @my_id while @@fetch_status <> -1 begin if @@fetch_status <> -2 begin insert #temp_table exec sp_mystoredprocedure @my_id end fetch next cursora @my_id end close cursora deallocate cursora how can transform select, example this: insert #temp_table exec sp_mystoredprocedure ida ... ? you can't directly query result set of stored procedure i'm afraid. presumably that's why cursor there in first place. using cursors thought inefficient, replace this: -- ids select ida #tmpids -- add row numbers , index query speed (may not needed if small) alter table #tmpids add rownum int identity(1,1) create clustered index idx_tmpids_rownum on #tmpids(rownum) declare @my_id int, @rownum int, @rowcount int set @rownum = 1 select @rowcount = count(*) #tmpids -- iterate on #tmpids while @rownum <= @rowcount begin selec

to create game object dynamically, take objecttypeid , unsigned int , , let compare within long switch() statement. if appropriate swith case found, create object , store it. because have 90 game objects, switch() long , growing 300 objects. to avoid long switch() statement, , improve speed, perfect candidate taking advantage of indexed array store object types (objecttypeid increases 0 upward). is there way, how store object type within array? i use this: aobjecttypesarray[objecttypeid] *pnewdynamicobject = new aobjecttypesarray[objecttypeid]; can advise me, please, how take advantage of dynamic array indexing in case, , how avoid long switch() statement? advice might differ idea, key use array indexing , remove long switch() statement. an easier way create factories use template create factory method , store using function pointer or perhaps boost::function or std::function if they're available. for example, given objects: #include <iostream&g

i have external application contacts on database server db1 ,second have magento database db2 in same server. want populate customer dropdown in adminpanel contacts information how can ? try use connect db: ` $config = array( 'host' => $data['db_host'], 'username' => $data['db_user'], 'password' => $data['db_pass'], 'dbname' => $data['db_name'] ); $connection = mage::getsingleton('core/resource')->createconnection('connection_name', 'pdo_mysql', $config); ` then on $connection can use fetchall() etc. and can prepare "dropdown" items if that's want.

i have list of articles in ul list. reading http://www.w3.org/wai/pf/aria/roles#role_definitions can either use roles list , listitem per item, considered article . option 1: can following (have 2 roles on same element): <ul role="list"> <li role="listitem article">...<li> </ul> option 2: should use article role: <ul> <li role="article">...<li> </ul> you should use option 3 :) <ul role="list"> <li role="listitem">...<li> </ul> all want let assistive technologies understand markup of content. actually, assisted technologies, "role" attribute required on rich internet content, sliders, , many html5 elements. if worried screen readers working code, marking such list correctly suffice. good example <p> list </p> <ul role="list"> <li role="listitem"> list item 1 <li> </ul&

possible duplicate: removing element array (java) is there way can rid of elements in array. instance, if have array int testarray[] = {0,2,0,3,0,4,5,6} is there "fast" way rid of elements equal 0 int resultarray[] = {2,3,4,5,6} i tried function got lost using lists public int[] getridofzero(int []s){ list<> result=new arraylist<>(); for(int i=0; i<s.length; i++){ if(s[i]<0){ int temp = s[i]; result.add(temp); } } return result.toarray(new int[]); } java arrays can't resized. need create new array. count non-zero elements in array. create new array size. copy elements old new array, skipping on 0 elements. you can lists. best bet create list of integers; add non-zero elements it; use toarray create array list.

i have ruby on rails controller display different form logged out user logged in user. what best way approach this? (is below way ok?) class userscontroller < applicationcontroller def index if logged_in && is_admin render 'admin_index' end #use default index end end sure thats fine except might 'cannot render action twice' type error (if im admin , logged in still try render default after rendering admin action) class userscontroller < applicationcontroller def index if logged_in && is_admin render 'admin_index' else render end end end might better

im trying overload [] operator in c++ can assign / values data structure dictionary used in c#: array["mystring"] = etc. is possible in c++? i attempted overload operator doesnt seem work, record& mydictionary::operator[] (string& _key) { (int = 0; < used; ++i) { if (records[i].key == _key) { return records[i]; } } } thanks. your code on right track - you've got right function signature - logic bit flawed. in particular, suppose go through loop without finding key you're looking for: for (int = 0; < used; ++i) { if (records[i].key == _key) { return records[i]; } } if happens, function doesn't return value, leads undefined behavior. since it's returning reference, going cause nasty crash second try using reference. to fix this, you'll need add behavior ensure don't fall off of end of function. 1 option add key table, return reference new table entry. behavior of st

on mac, using mono 2.6, , wanting started protobuf-csharp-port. i compiled protoc protobuf-2.3.0 google. or should use protobuf-2.4.0 came out? protobuf-csharp-port should use download of 0.9.1 (may 2010) or go ahead , clone git master branch? so, looks compiled addressbook tutorial using 2.3.0 + 0.9.1. wanting know if it's advisable go protoc 2.4.0 + git master? thanks in advance , looking forward digging in protobuf-csharp-port. alex i can't i've used protobuf-csharp-port on mac. it's probably best go 2.3.0 build of protobuf that's version of protoc use on windows. i suggest using latest version of protobuf-csharp-port on github; includes few new features in protogen such automatically calling protoc - although assumes protoc.exe, you'll need tinker call mac version. can specify various of generation options command line instead of "polluting" otherwise portable .proto file, nice. unfortunately don't have documentation yet

my code calculate minimum translation vector using separating axis theorem works well, except when 1 of polygons contained polygon. have scoured internet solution problem , seems ignore ( http://www.codezealot.org/archives/55#sat-contain talks this, doesn't give full solution...) the pictures below screenshot program illustrating problem. translucent blue triangle position of rectangle before mtv applied, , other triangle mtv applied. it seems me link shared give solution this. in mtv calculation, have test complete containment in projection , change calculations accordingly. (the pseudocode in reference figure 9 on page.) perhaps if post code, can comment on why isn't working.

possible duplicate: remove duplicates list is there method in java list can use remove duplicates? no, there no method on java.lang.list removes duplicates. seems designers expected list not used in scenarios worried duplicates: unlike sets, lists typically allow duplicate elements. more formally, lists typically allow pairs of elements e1 , e2 such e1.equals(e2), , typically allow multiple null elements if allow null elements @ all. not inconceivable might wish implement list prohibits duplicates, throwing runtime exceptions when user attempts insert them, expect usage rare. (taken java.lang.list javadoc ) you either need use set or implement own method removing duplicates.

i'm using redbean php dump data web scrape database, , need retain legacy ids, preferably primary key field. possible redbean? when try set id so: $bean->id = 56; the row doesn't inserted - query ends being created instead becomes "update id =56", nothing since record doesn't exist yet. forcing specific value on auto-increment primary index asking race-condition problems. i'd suggest create new column legacy_id instead save alternative id.
