[vtkusers] not able to view .vtk file in 3D view

[Gururajan]

yes, thats what i mentioned, i have created .vtk files from reading
series of dicom files, my written (.vtk) files  are not displaying in my
application, thats y i attached my source for creating .vtk file and
displaying in the control. Please have look at it and guide me.,

i have used most of the writer to to write .vtk file
please see the below findings
Thanks
Guru
