[vtkusers] vtkStructuredPointsReader Question

[Lukasz Czopyk]

Hallo All,
I am very new user of VTK package and unfortunately not advanced c++ 
programist (I use Builder c++ 6.0). I want to use vtkStructuredPointsReader 
and trying to get used to this I tryed to run following program. Procedure 
compiles ok. but after getting run it hangs up and the Exeption 
"classEAccesViolation at address...." is thrown.I was playing around it about 
two days but have no idea what to do.
Can anyone help me? I would be very grateful for any help?

Lukasz
P.S. the path to ironProt.vtk should be changed I think.
