-====== Creating Rhino C++ Plugins that use the Zoo ======
-> **Developer:** //[[developer:zoo|Zoo 5.0]]//
-> **Summary:** //Discusses how to create Rhino 5.0 plugins that can obtain licenses from the Rhino license manager and the Zoo.//
-===== Overview =====
-Zoo 5.0 allows 3rd party plug-in developers to add licensing support for their products to the Zoo.
-The Rhino 5.0 C++ SDK allows developers to write plug-ins for Rhino that use the Rhino license manager and obtain licenses from Zoo servers.
-===== Requirements =====
-Rhino C++ plug-ins are MFC dynamic link libraries. Thus, to create a plug-in for Rhino, you will need one of the following development tools:
-  - Microsoft Visual C++ 2005 (required for Rhino 5.0 32-bit)
-  - Microsoft Visual C++ 2010 (required for Rhino 5.0 64-bit)
-  - [[http://wiki.mcneel.com/developer/sdksamples/rhino5wip|Rhino 5.0 C++ SDK]]
-Note, the Express Editions of Microsoft Visual Studio will **not** work, as they do not include MFC.
-Also, all Rhino plug-ins that use the Rhino license manager to access the Zoo must be signed with an Authenticode certificate issued by McNeel Plug-in Security. These certificates are free, but must be requested by each developer. Developers must agree to the //Terms of Use// before a certificate is issued. For more information on plug-in signing, see the following:
-[[developer:digital-signatures/create-request|Digitally Signing Plug-ins]]
-===== Creating a Rhino C++ Plug-in =====
-The following are the general steps required to create a Rhino plug-in.
-  - Make sure you have the [[http://www.rhino3d.com/nr.htm|Rhino 5.0]] installed.
-  - Make sure you have the [[http://wiki.mcneel.com/developer/sdksamples/rhino5wip|Rhino 5.0 C++ SDK]] installed.
-  - Launch Microsoft Visual Studio 2010.
-  - Create a new project, in C++, based on the **Rhino 5.0 Plug-in** project template.
-  - Build your plug-in.
-  - Launch Rhino and use **PlugInManager** to install your plug-in (to verify that it was built properly).
-===== Adding Licensing Support to your Plug-in Project =====
-After you have built and tested your basic plug-in, you can add licensing support as follows:
-  - Add a new .CPP file to your project.
-  - In this .CPP file, declare a new class that is derived from **CRhinoLicenseValidator**.
-  - Override the **CRhinoLicenseValidator::ProductBuildType** virtual function and return the build type of the license that your product requires.
-  - Override and implement the **CRhinoLicenseValidator::ValidateProductKey** virtual function. Rhino will call into this function whenever it needs your plug-in to validate a license that is entered by a user, returned by the Rhino license manager (standalone node), or returned from a Zoo server (network node). For details, see the example Rhino C++ plug-in listed below.
-  - Create one (and only one) static instance of your object.
-  - In your plug-in's  **CRhinoPlugIn::OnLoadPlugIn ** member, call  **CRhinoPlugIn::GetLicense** to get a license.
-  - Build your plug-in.
-  - [[developer:digital-signatures/create-request|Digitally sign your plug-in.]]
-  - Launch Rhino and test your plug-in. When your plug-in is loaded for the first time, you will be prompted to enter a license.

-===== Managing your License =====
-Rhino plug-ins that use the Rhino license manager appear in the Licenses page of the Options dialog. Here, the user is allowed to view and manage the license.
