# OnSynchronizationOver Method of the IComponentSynchronizerEvents Interface

> OnSynchronizationOver method of the IComponentSynchronizerEvents Interface in ABBYY FineReader Engine Visual Components on Windows — This method is implemented on the client-side.

This method is implemented on the client-side. It is called by ABBYY FineReader Engine after [Component Synchronizer](/fine-reader/engine/visual-components-reference/supplementary-objects/componentsynchronizer) has finished synchronization.

The method delivers to the client information on the operation which has required synchronization.

## Syntax

### C++

```cpp theme={null}
HRESULT OnSynchronizationOver( SynchronizationOperationEnum Operation );
```

### C\#

```csharp theme={null}
void OnSynchronizationOver( SynchronizationOperationEnum Operation );
```

### Visual Basic .NET

```vb theme={null}
Sub OnSynchronizationOver(Operation As SynchronizationOperationEnum)
```

## Parameters

Operation

\[in] Specifies the type of the operation. See the description of the [SynchronizationOperationEnum](/fine-reader/engine/visual-components-reference/enumerations/synchronizationoperationenum) constants.

## Return values

\[C++ only] If this method returns a value other than S\_OK, it indicates that an error occurred on the client-side.

## Remarks

The client implementation of this method must assure that all exceptions thrown inside the method are caught and handled and no exceptions are propagated outside the method. Propagation of an exception outside the method may lead to unpredictable results (such as program termination).
