AddInController Class

Use this class to perform the following tasks:

• Use the AddInEnvironment property to obtain an AddInEnvironment object for an add-in. Then use that object to activate other add-ins in the same application domain and process as the original add-in.

• Use the AppDomain property to obtain an AppDomain object for an add-in. Then use that object to activate other add-ins in the same application domain as the original add-in. Note that because of limitations in cross-process remoting, this scenario will not work with add-ins that are activated in a separate process.

• Use the Token property to obtain an AddInToken object that represents an add-in.

• Shut down an add-in with the Shutdown method.

To obtain the controller for an add-in, call the GetAddInController method and pass an instance of the add-in as its parameter.

The following example activates an add-in within the same environment as a previously activated add-in by using an AddInController object.

// Get the AddInController of a  
// currently actived add-in (CalcAddIn).
AddInController aiController = AddInController.GetAddInController(CalcAddIn);

// Select another token.
AddInToken selectedToken2 = ChooseAddIn(tokens);

// Activate a second add-in, CalcAddIn2, in the same 
// appliation domain and process as the first add-in by passing 
// the first add-in's AddInEnvironment object to the Activate method.
AddInEnvironment aiEnvironment = aiController.AddInEnvironment;
Calculator CalcAddIn2 =
	selectedToken2.Activate<Calculator>(aiEnvironment);

// Get the AddInController for the second add-in to compare environments.
AddInController aiController2 = AddInController.GetAddInController(CalcAddIn2);
Console.WriteLine("Add-ins in same application domain: {0}", aiController.AppDomain.Equals(aiController2.AppDomain));
Console.WriteLine("Add-ins in same process: {0}", aiEnvironment.Process.Equals(aiController2.AddInEnvironment.Process));
