[Insight-users] Smart pointer destruction

[Diego Parada]

Hi,

I used the UpdateLargestPossibleRegion() :

connector->SetInput(this->GetDocument()->m_Imagen);
try
{
connector->GetExporter()->UpdateLargestPossibleRegion();
connector->GetExporter()->Update();
connector->Update();
}
catch( itk::ExceptionObject & err )
{
MessageBox(err.what(),"Alerta",MB_ICONERROR);
return;
};
m_imagen=connector->GetOutput();

but dont appera anything y the renderwindow.

Can You help me?
