# PagesRenumbered Method of the IFRPagesEvents Interface

This method is implemented on the client-side. It is called by ABBYY FineReader Engine for some of the methods of the [FRPages](/fine-reader/engine/api-reference/document-related-objects/frpages) object. It delivers to the client information about pages renumbering completed.

<Note>
  In Windows, it can also process any system messages to help prevent the application from appearing unresponsive during long operations. This can be helpful in applications with a user interface.

## Syntax

### C++

```cpp theme={null}
HRESULT PagesRenumbered( IFRPages* Sender );
```

### C\#

```csharp theme={null}
void PagesRenumbered( FRPages Sender );
```

### Visual Basic .NET

```vb theme={null}
Sub PagesRenumbered(Sender As FRPages)
```

## Parameters

Sender

\[in] This parameter refers to the [FRPages](/fine-reader/engine/api-reference/document-related-objects/frpages) object which sends notifications.

## 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).
