The problem of search in Memc

Babulesnik · 08-07-2011 10:19 AM

I'm writing a class that is responsible for a list of all users who have been authorized.
When using Memc.find ()

Code:

bool FindUser(Str Login)

  {

      ColumnsUserList.Login=Login;

      if(MemUserList.find(ColumnsUserList))

      return true;

  }

error:

Code:

>          d:\microsoft visual studio 10.0\vc\include\esenthelengine\memory\mem continuous.h(43) : while compiling class template member function 'Int EE::Memc<TYPE>::find(const TYPE &) const'

1>          with

1>          [

1>              TYPE=StructColumnList

1>          ]

Сlass сode:

Code:

struct StructColumnsList

{

    Str Adress;

    Str    Login ;

    Str    Nick  ;

    Flt Money ;

}ColumnsUserList;

struct StructUserList  

{

  Memc<StructColumnsList>MemUserList;

  bool AddUser (Str &Adress , Str &Login , Str &Nick , Flt &Money )

  {

      ColumnsUserList.Adress =Adress;

      ColumnsUserList.Login  =Login ;

      ColumnsUserList.Nick   =Nick  ;

      ColumnsUserList.Money  =Money ;

      MemUserList.add(ColumnsUserList);

      return true;

  }

  bool FindUser(Str Login)

  {

      ColumnsUserList.Login=Login;

      if(MemUserList.find(ColumnsUserList))

      return true;

  }

  bool DeleteUser (Str &Login)

  {

    return true;

  }

}UserList;

I am not to understand that for a constant value should be there

I wrote my method,it works fine:

Code:

int FindUser(Str Login)

  {

      ColumnsUserList.Login=Login;

      FREPA(MemUserList)

      {

          if(T.MemUserList[i].Login==Login)return i;

      }

      return -1;

  }

But really want to understand why an error occurs when using the method of Memc smile

probably you'd need to make StructColumnsList operator ==

The same error and memc <struct>. Save (File & file)

PHP Code:

struct StructRoomNormal // бесплатная комната для гуи клиента
{
    Byte Number        ;
    Str  NameRoom      ;
    Str  PlayersInRoom ;
};
struct StructRoomsList //Kласс список комнат
{
  Memc<StructRoomNormal>MemRoomsNormalList ; //список бесплатных комнат

  StructRoomNormal RoomNormal ; 
...
...
  bool ReturnNormalRooms ( File &f ) ;
}; 

If I try to compile the method of preservation. Save () I get an error

PHP Code:

bool StructRoomsList::ReturnNormalRooms( File &f )
  {
      T.MemRoomsNormalList.save(f);
  }

you should check the source of MemRoomsNormalList.save

you're missing
void StructRoomNormal::save(File &f)
and
Bool StructRoomNormal::load(File &f)

Ie, that would keep all the lines the container MemRoomsNormalList I need to write code like this?

FREPA(MemRoomsNormalList)
{
MemRoomsNormalList[i].save(f)
}
