[vtkusers] VTK and C# in Visual Studio 2010

[Eric E. Monson]

Hey Wisam,

(Please respond to the mailing list, too, so everyone can contribute and learn together.)

I've had problems with some of the examples that come with the ActiViz.NET wrappers crashing (like the Wikipedia browser), but most of them work fine for me. 

There are some unresolved problems with using the 2D Charts API (vtkChartXY, etc) with the .NET wrappers though, related to interaction. Here's a short thread from February dealing with that issue: 
http://vtk.1045678.n5.nabble.com/Activiz-and-vtkChartXY-td3397315.html

The example you linked to, though, is a C++ example rather than C#... If you're wanting to use C++ you just need "plain" VTK and CMake rather than the ActiViz.NET wrappers for C#/.NET.

The ActiViz.NET examples get installed in C:\Program Files\ActiViz.NET 5.6.1 OpenSource Edition\Examples (or similar path depending on whether you're using the 32 or 64-bit versions and which version of Windows). If everything installed properly you should be able to open the supplied C# VS solution files and build and run. To try other examples you'll have to translate them yourself to C#/.NET

Otherwise, you'll have to give us more details about what you're trying to do and what's going wrong so someone can try to help.

-Eric

The part that is limited to not work with VS 2010 is creating the wrappers yourself. So, if you can use the release binary versions for what you want to build, then there's no problem using VS 2010. (Hopefully a new VTK release will be coming soon, so the C# wrappers will get updated, also.) If you need to write custom C++ classes or subclasses to extend VTK, then part of the wrapping process is limited to VS 2008, but I think you can then still use those .dlls with building applications using VS 2010.
