[Insight-users] How to re-use an itk ImageFileReader?

[Hua-Mei Chen]

Hi,

  I used the following code to read image data. However, my program had an 
error message "Access violation reading location 0xfeeefefe." the second 
time m_ImageFileReader->Delete( ) was invoked. Can anyone tell what goes 
wrong in my code? Thank you.

while (continue){

if (m_ImageFileReader != (void*) 0) m_ImageFileReader->Delete( );
m_ImageFileReader = ImageFileReaderType::New();
m_ImageFileReader->SetFileName( m_InputFileName);
m_InputImage = m_imageFileReader->GetOutput();
m_ImageFileReader->Update();
...
...
}

Chen
