[vtkusers] GetNumberOfPoints() of vtkPoints

[Ming Chao]

Hi David,
Thanks for looking into this.


Do you have multiple versions of VTK dll's in your PATH?


I do have another vtk version (5.0.4) after I had this problem with
5.2.0.But I believe 5.0.4 was not included. I am not sure what you
mean by PATH.
Anyhow, I checked Path in the System vairables. I did not put any version of
 VTK in it. If there is other PATH, please let me how to check.

When I run the program in debugger mode, it immediately brought me to the
crtexe.c file. How do I find out whether VTK 5.3 dlls are loaded or not? I
have to say that I am not quite good at Visual Studio debugging stuff.
