[vtkusers] Modifying and building vtk dotnet code.....

[Theodore Holden]

Hi....

I need some sort of a handle into the dotnet wrapper (SourceForge) for VTK.  

The obvious place for it is vtkSimplePointsReader.  That is provided with VTK as a model for designing readers and if I could modify and build it I could easily enough make it do what I need it to do, i.e. modify the RequestData function to take data from values already in memory rather than write and then re-read .vtk files.

Nonetheless the system appears highly resistent to any attempts at modifying anything.  Attempts to modify the PrintSelf function to return a recognizable string of my own choosing appear to compile and build but behave as if I had not made changes when using the function and an attempt to insert a function of my own, i.e.

const char *bearFunction()
    {          
            return "Bears rule!!!!";
    }

compiles but produces the following:

Linking...

Likewise every other thing I've tried to insert something miniscule just to convince myself I'd succeeded in modifying this thing and having it build is rejected one way or another.  At least one other .h/.cxx pair contains an include for <vtk/std/string and a function which returns 

vtkstd::string errorMessage;

or some such;  when I try it the compiler has no clue what I'm referring to.  I get the distinct impression I'm looking at something the wrong way and would appredciate any thoughts anybody might have.
