c++ - Use Octave in msvc 2010 -

-

i using octave within msvc 2010. first downloaded octave latest version @ link. after installing, tried run simple code:

#include <iostream> #include<octave-3.6.4\octave\oct.h> #include<octave-3.6.4\octave\config.h> #include<octave-3.6.4\octave\octave.h>  using namespace std;   int main (void) {   std::cout << "hello octave world!\n";       system("pause");   return 0;   }

note added these links project well:

  1. c:\software\octave-3.6.4\include\octave-3.6.4\octave--->includ. dir.,
  2. c:\software\octave-3.6.4\include--->includ. dir.
  3. c:\software\octave-3.6.4\lib--->lib. dir.
  4. c:\software\octave-3.6.4\lib\octave\3.6.4--->lib dir.
  5. i added 1 , 2 additional inc dir!!
  6. c:\software\octave-3.6.4\lib\octave\3.6.4--->additional lib. dir in linker.

first, got error cannot find math.h in program files while file in program files (x86). so, changed to: c:\program files (x86)\microsoft visual studio 10.0\vc\include\math.h , solved error. however, error:

error lnk2019: unresolved external symbol "__declspec(dllimport) public: __thiscall octave_value::~octave_value(void)" (__imp_??1octave_value@@qae@xz) referenced in function "public: void * __thiscall octave_value::`vector deleting destructor'(unsigned int)" (??_eoctave_value@@qaepaxi@z)

it not sufficient add library path project.

you have add library name(s) (including .lib) "additional dependencies" in linker/input tab.

edit

to verify library has been searched can enable linker/general/show progress option. can see in build output library has used in symbol search.

edit

your example code doesn't show instance of array of octave_value instances. it's bit surprising need link library code you've shown. anyway want have these externals resolved.

if there no other resource (manual, ...) should detect octave_value class implemented. can static library or dll.

you can detect dll implementation dumpbin /exports on dlls. in case need corresponding import libraries. lib should have same base name dll. verify have added dependency , how linker searches library symbols.

the name of symbols __imp_??1octave_value@@qae@xz indicates should in dll. since have problem might want search libs too. can detect lib implementation dumpbin /symbols. in case have add lib directly. again verify build output.

the dumpbin output verbose. should use either findstr limit output or redirect output file , search symbols editor of choice.

search ocatave_value. if find different decoration of constructor , destructor might have missed set option. preprocessore directory used define how library use. e.g. if find octave_value::octave_value without __imp_ prefix have accidentily compiled dll version altough class implemented in static library. in case, read manual , ask @ octave mailing list forum or whatever.

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

here's current code creating index jsonb. index("mytable_data_idx_id_key", mytable.data['id'].astext, postgresql_using='gin') but got error. sqlalchemy.exc.programmingerror: (psycopg2.programmingerror) data type text has no default operator class access method "gin" hint: must specify operator class index or define default operator class data type. [sql: "create index event_data_idx_id_key on event using gin ((data ->> 'id'))"] is there way create index on sqlalchemy? the postgresql specific sqlalchemy docs @ http://docs.sqlalchemy.org/en/latest/dialects/postgresql.html#operator-classes mention postgresql_ops dictionary provide "operator class" used postgresql, , provide example illustrating use: index('my_index', my_table.c.id, my_table.c.data, postgresql_ops={ 'data': 'text_pattern_ops',

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
