[Insight-users] ITK run-time error from DLL

[Luis Ibanez]

Hi Abhishek,

Please add a try/catch block around the invokation of


       ImageType::Pointer image =  ImageType::New()

and print out the error message returned by the exception.


For examples on how to use try/catch blocks please look
at the ITK Software Guide:

    Regards,


        Luis
