# CopyFrom Method

<Note>
  This is a common method. Any platform-specific implementation limitations will be listed in the topics for the objects using this method.
</Note>

This method initializes the properties of the current object with the values of similar properties of another object.

## Syntax

### C++

```cpp theme={null}
HRESULT CopyFrom( I<ObjectType>* From );
```

### C\#

```csharp theme={null}
void CopyFrom(I<ObjectType> From);
```

### Visual Basic .NET

```vb theme={null}
Sub CopyFrom(From As I<ObjectType>)
```

## Parameters

From

\[in] This variable refers to the object of the same type as the current one. This object serves as a source of data to be copied into the new object.

## Return values

This method has no specific return values. It returns the [standard return values of ABBYY FineReader Engine functions](/fine-reader/engine/api-reference/return-codes).
