# 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;
|
||
}
|
||
|
||
```
