[Insight-users] How to convert VTK example (console based) to MFC based

[paulus joo]

Hi Luis and ITK Mania

I run the ITKImage2VTKImage.cxx with MSVC in console mode. It work fine but when I tried to convert it to MFC based, it  fail in compilation stage. I plan to display the image in a Dialog. Below are the codes.

What part should I bring to constructor, destructor and so on..

Thank you in advance.
Best Regards
