Load

Loads list data from the file.

virtual bool  Load(
   int  file_handle      // file handle
   )

Parameters

file_handle

[in] Handle of the binary file previously opened using the FileOpen () function.

Return Value

true - successfully completed, false - error.

Note

When reading list elements from the file, the CList::CreateElement(int) method is called to create each element.

Example:

//--- example for CLoad::Load(int)
#include <Arrays\List.mqh>
//---
void OnStart()
  {
   int    file_handle;
   CList *list=new CList;
   //---
   if(list!=NULL)
     {
      printf("Object create error");
      return;
     }
   //--- open file
   file_handle=FileOpen("MyFile.bin",FILE_READ|FILE_BIN|FILE_ANSI);
   if(file_handle>=0)
     {
      if(!list.Load(file_handle))
        {
         //--- file load error
         printf("File load: Error %d!",GetLastError());
         delete list;
         FileClose(file_handle);
         //---
         return;
        }
      FileClose(file_handle);
     }
   //--- use list elements
   //--- . . .
   //--- delete list
   delete list;
  }
