Save
Save
Saves list element data in a file.
virtual bool Save(
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
Save(int) method in CObject class always returns ’true’ and does not perform any action. If you want to save the data of a derived class in a file, the Save(int) method should be implemented.
Example:
//--- example for CObject::Save(int)
#include <Object.mqh>
//---
void OnStart()
{
int file_handle;
CObject *object=new CObject;
//---
if(object!=NULL)
{
printf("Object create error");
return;
}
//--- set objects data
//--- . . .
//--- open file
file_handle=FileOpen("MyFile.bin",FILE_WRITE|FILE_BIN|FILE_ANSI);
if(file_handle>=0)
{
if(!object.Save(file_handle))
{
//--- file save error
printf("File save: Error %d!",GetLastError());
delete object;
FileClose(file_handle);
//---
return;
}
FileClose(file_handle);
}
delete object;
