Ahojte ucim sa RoR a narazil som sa na problem kedy potrebujem dostat aktualne stavy checkboxov z view to controllera bez pouzitia submit_tag.

Mam napriklad taktu skupinu checkboxov:

= form_tag cars_path, :method => :get do
  Include: 
  - @all_ratings.each do |rating|
    = rating
    = check_box_tag "ratings[#{rating}]"
  = submit_tag 'Refresh'

V controller ziskam zaskrtnute stavy pomocou  

params[:ratings].keys

A chcel by som tieto zaskrnute stavy dostat do controllera ked napriklad kliknem na hlavicku v tabulke:

%th Title

Vedeli by ste niekto poradit ako na to?

J diki. Nakoniec som pouzil Interop kvoli tomu, ze som potreboval pracovat s formatom .doc

Ahojte, mam vytvoreny konfiguracny subor v priecinku bin\Debug\settings.config. Nasledujucimi metodami sa chcem ulozit zmeny v subore:

 Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

 config.Save(ConfigurationSaveMode.Modified);
 ConfigurationManager.RefreshSection("appSettings");
 config.Save();

Zmeny sa v subore neprejavia a hodnoty sa neaktualizuju. Neviete ako by som zmene hodnoty mohol zapisat do konfiguracneho suboru?

Dikes, o tej Open XML SDK som vobec nevedel, vyzera to ako najrozumnejsie riesenie

Ahojte, chcel by som sa spytat na tuto chybu, ako by som ju mohol vyriesit

template<class _Other1,
		class _Other2>
		_Pair_base(_Other1&& _Val1, _Other2&& _Val2)
		: first(_STD forward<_Other1>(_Val1)),
			second(_STD forward<_Other2>(_Val2))
		{	
		}

	_Ty1 first;	
	_Ty2 second;	
	};

error C2440: 'initializing' : cannot convert from 'int' to 'const PP_PropertyType 

error C2439: 'std::_Pair_base<_Ty1,_Ty2>::second' : member could not be initialized 

Aj ked si niesom isty ci tento kus kodu staci, za kazdu radu budem vdacnny

Ahojte, chcel by som previest XML do grafickej podoby, skusal som nastroj GraphViz ale nedari sa mi to..

 Ukazka XML suboru:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
    <EFG>
        <Events>
            <Event>
                <EventId>e2755731202</EventId>
                <Type>SYSTEM INTERACTION</Type>
                <Listeners>Project$W1Listener</Listeners>
            </Event>
            ...
       </Events>
       <EventGraph>
        <Row>
            <E>1</E>
            <E>1</E>
            <E>0</E>
            <E>0</E>
            <E>0</E>
        </Row>
        ...
   </EventGraph>
</EFG>

Chybova hlaska:

Error: <gvedit>:1: syntax error near line 1
context: <?xml version="1.0" encoding="UTF-8" standalone="yes" >>>  ?> <<<

Vedeli by ste niekto poradit ako XML prevediem do grafickej podoby?

Ahojte, nedari sa mi rozbehat nastroj GUITAR, ktory sluzi na testovanie GUI a sklada sa v podstate zo styrok nastrojov. Prvy je ripper, ktory prebehne zdrojovy kod GUI o ktorom ulozi nejake info. Druhy je gui2efg, ktory tieto info prevedie na subor, z ktoreho sa da vykreslit diagram GUI komponent, potom je tam tc-gen-seq, co je test case generator, ktory vytvori testovacieho priapdy z grafu a posledny je jfc-replayer, ktory vykona testovacie pripady a ulozi vysledky z testov.

http://sourceforge.net/apps/mediawiki/guitar/index.php?title=Main_Page

Ked pustim prvu utilitu cez Cygwin jfc-ripper.sh s pozadovanymi parametrami vyhodi mi to chybu:

java.lang.NoClassDefFoundError: edu/umd/cs/guitar/ripper/JFCRipperMain

Vedeli by ste niekto poradit co s tym?

Ahojte, nedari sa mi vlozit hlavicky z Windows Driver Kit. Hlavicky vkladam postupne, pricom subory som skopiroval priamo do projektu podla screenu nizsie. Neviete niekto, co robim zle?

#2 KIIV

Stacil ten OPEN_ALWAYS, mohlo ma to napadnut.. Diki   

Ahojte, na MSDN som nasiel kus kodu pomocou ktoreho mozem zapisovat text na koniec suboru. Vo funkcii CreateFile je priznak OPEN_EXISTING, cize mi nevie vytvorit textovy subor, ked som to zmenil na CREATE_ALWAYS tak sa vzdy text zapisuje na zaciatok suboru. Vedeli by ste mi poradit ako to prerobit tak aby mi tento kus kodu aj vytvoril textovy subor? Napada ma pred createfile vytvorit este jeden createfile kde bude CREATE_ALWAYS ale to mi nepride ako elegantne riesenie.

#include <windows.h>
#include <tchar.h>
#define FILE_WRITE_TO_END_OF_FILE       0xffffffff

int
_tmain(int argc, _TCHAR* argv[])

 HANDLE hFile = ::CreateFile(L"Test.txt",

        OPEN_EXISTING,
        FILE_ATTRIBUTE_NORMAL,
        0);

  return ::GetLastError();
