Load
Load
Loads list element data from a file.
virtual bool Load(
int file_handle // file handle
)Parameters
- file_handle
[in] Handle of the binary file opened earlier using the FileOpen() function.
Return Value
true – successfully completed, false - error.
Note
Load(int) method in the CObject class always returns ’true’ and does not perform any action. If you want to load the data of a derived class from a file, the Load(int) method should be implemented.
Example:
//--- example for CObject::Load(int)
#include <Object.mqh>
//---
void OnStart()
{
int file_handle;
CObject *object=new CObject;
//---
if(object!=NULL)
{
printf("Object create error");
return;
}
//--- open file
file_handle=FileOpen("MyFile.bin",FILE_READ|FILE_BIN|FILE_ANSI);
if(file_handle>=0)
{
if(!object.Load(file_handle))
{
//--- file load error
printf("File load: Error %d!",GetLastError());
delete object;
FileClose(file_handle);
//---
return;
}
FileClose(file_handle);
}
//--- use object
//--- . . .
delete object;
