Hi Pirouz,

You need to find RhinoCommon.dll and Grasshopper.dll (with GH_IO.dll) after choosing "Browse".

Rhino 5 64 bit on my system is located in:
%programfiles%\Rhinoceros 5.0 (64-bit)\System\
Here I have RhinoCommon.dll.

And the latter file is in: %appdata%\McNeel\Rhinoceros\5.0\Plug-ins\Grasshopper {B45A29B1-4343-4035-989E-044E8580D9CF}\0.9.61.0\

I hope this helps

Giulio

Hi Guilio, 

Thank you very much for your response. It was actually a funny issue with the location of my Grasshopper and Rhino on my hard drive. I have them referenced now; but I was wondering if you are going to update the template you had prepared for GHA files sometime. It doesn't work with my VS 2012 and I don't have a VS 2010 to install. When I open the last GHA project I had written using your template my VS crashes. That template was a great starting point indeed!

Thanks for reminding me, Pirouz :)

I've actually updated these templates -- Grasshopper addons and RhinoCommon plugins:

https://github.com/mcneel/RhinoCommonTemplatePackage
https://github.com/mcneel/GrasshopperTemplatePackage

I think Steve wanted to add some minor changes to the RhinoCommon one, and we need to make small changes to the Grasshopper one because we recently switched to .Net 4.0

Otherwise, they should be ready for the next release.

Thanks,

Giulio

Hi Guilio,

Thanks for letting me know! BTW, could you please explain how I can generate an error message in VS? I have found the "AddRuntimeMessage" Sub; but I don't know how I can trigger this method in case, for instance, an input fails to receive data or its data count is not matching with some other input. Because, in this case, those input parameters are in the scope of the SolveInstance Sub and not this sub; so I cannot refer to them. 

Public Overrides Sub AddRuntimeMessage(level As GH_RuntimeMessageLevel, text As String)
 MyBase.AddRuntimeMessage(GH_RuntimeMessageLevel.Warning, "number of labels and points must be equal")
End Sub

The thing is, when I noticed your response I had already made a template by my self and I didn't manage to use your template. Maybe I am missing some very important adjustment, which is already in your template!?

Thanks for your time,

Pirouz

That method is supposed to be called from SolveInstance. You do not need to override it. So you can just write:

AddRuntimeMessage(GH_RuntimeMessageLevel.Warning, "number of labels and points must be equal")

from within SolveInstance (probably from inside an "If")

I hope this helps,

Giulio

Dear All,

The grasshopper version 0.9.76.0 I found under following path:

C:\Program Files\Common Files\McNeel\Rhinoceros\5.0\Plug-ins\Grasshopper (b45a29b1-4343-4035-989e-044e8580d9cf)\0.9.76.0\Grasshopper.dll

What also could be helpful is to switch first to the framework 4.0 and add references after. 

Best

Dimitry
