Activate<T>(AddInEnvironment)

Activates an add-in in the environment of another add-in.

public:
generic <typename T>
 T Activate(System::AddIn::Hosting::AddInEnvironment ^ environment);

public T Activate<T> (System.AddIn.Hosting.AddInEnvironment environment);

member this.Activate : System.AddIn.Hosting.AddInEnvironment -> 'T

Public Function Activate(Of T) (environment As AddInEnvironment) As T

Type Parameters

T

The interface or abstract base type that represents the host view of the add-in.

Parameters

environment: AddInEnvironment

The application domain and process that contains the original add-in.

Returns

The host view of the add-in.

Examples

The following example activates one add-in in an automatically generated application domain with a specified security level. It then activates a second add-in in the same application domain and process as the first by using the first add-in's AddInEnvironment 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));

' Get the AddInController of a 
' currently activated add-in (CalcAddIn).
Dim aiController As AddInController = AddInController.GetAddInController(CalcAddIn)

' Select another token.
Dim selectedToken2 As AddInToken = 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.

Dim aiEnvironment As AddInEnvironment = aiController.AddInEnvironment
Dim CalcAddIn2 As Calculator = _
    selectedToken2.Activate(Of Calculator)(aiEnvironment)

' Get the AddInController for the second add-in to compare environments.
Dim aiController2 As AddInController = 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))

Remarks

This method overload activates the add-in in the same application domain and process as the add-in from which environment was obtained.

Applies to

Activate<T>(AddInSecurityLevel)

Activates an add-in with a specified trust level in a new application domain.

public:
generic <typename T>
 T Activate(System::AddIn::Hosting::AddInSecurityLevel trustLevel);

public T Activate<T> (System.AddIn.Hosting.AddInSecurityLevel trustLevel);

member this.Activate : System.AddIn.Hosting.AddInSecurityLevel -> 'T

Public Function Activate(Of T) (trustLevel As AddInSecurityLevel) As T

Type Parameters

T

The interface or abstract base type that represents the host view of the add-in.

Parameters

trustLevel: AddInSecurityLevel

One of the enumeration values that specifies the trust level.

Returns

The host view of the add-in.

Examples

The following example shows how to activate an add-in, identified by the chosen token, in an automatically generated application domain with a specified security level.

//Ask the user which add-in they would like to use.
AddInToken selectedToken = ChooseAddIn(tokens);

//Activate the selected AddInToken in a new
//application domain with the Internet trust level.
Calculator CalcAddIn = selectedToken.Activate<Calculator>(AddInSecurityLevel.Internet);

//Run the add-in using a custom method.
RunCalculator(CalcAddIn);

'Ask the user which add-in they would like to use.
Dim selectedToken As AddInToken = ChooseAddIn(tokens)
'Activate the selected AddInToken in a new
'application domain with the Internet trust level.
Dim CalcAddIn As Calculator = selectedToken.Activate(Of Calculator)(AddInSecurityLevel.Internet)
'Run the add-in using a custom method.
RunCalculator(CalcAddIn)

Remarks

This method overload loads the add-in into an automatically generated application domain. If you want to specify a name for the new application domain, use the Activate<T>(AddInSecurityLevel, String) overload.

This method sets the base directory for the application domain to be the location of the add-in assembly. It also looks for the configuration file [addinassemblyname].dll.config and, if found, sets it to be the configuration file for the new application domain.

Applies to

Activate<T>(AppDomain)

Activates an add-in in an existing application domain.

public:
generic <typename T>
 T Activate(AppDomain ^ target);

public T Activate<T> (AppDomain target);

member this.Activate : AppDomain -> 'T

Public Function Activate(Of T) (target As AppDomain) As T

Type Parameters

T

The interface or abstract base type that represents the host view of the add-in.

Parameters

target: AppDomain

The application domain that the add-in should be activated in.

Returns

The host view of the add-in.

Exceptions

SecurityException

Full-trust permission is demanded. A caller in the call chain does not have sufficient permission.

Examples

The following example activates an add-in in an application domain that is being used by another add-in. The code for the first add-in is provided in the AddInToken class.

// Get the application domain
// of an existing add-in (CalcAddIn).
AddInController aiCtrl = AddInController.GetAddInController(CalcAddIn);
AppDomain AddInAppDom = aiCtrl.AppDomain;

// Activate another add-in in the same application domain.
Calculator CalcAddIn3 =
    selectedToken2.Activate<Calculator>(AddInAppDom);

// Show that CalcAddIn3 was loaded
// into CalcAddIn's application domain.
AddInController aic = AddInController.GetAddInController(CalcAddIn3);
Console.WriteLine("Add-in loaded into existing application domain: {0}",
    aic.AppDomain.Equals(AddInAppDom));

' Get the application domain
' of an existing add-in (CalcAddIn).

Dim aiCtrl As AddInController = AddInController.GetAddInController(CalcAddIn)
Dim AddInAppDom As AppDomain = aiCtrl.AppDomain

' Activate another add-in in the same appliation domain.
Dim CalcAddIn3 As Calculator = selectedToken2.Activate(Of Calculator)(AddInAppDom)

' Show that the CalcAddIn3 was loaded
' into CalcCaddIn's application domain.
Dim aic As AddInController = AddInController.GetAddInController(CalcAddIn3)
Console.WriteLine("Add-in loaded into existing application domain: {0}", _
 aic.AppDomain.Equals(AddInAppDom))

Remarks

To activate an add-in in an automatically generated application domain, use the Activate<T>(AddInSecurityLevel) overload to generate a new application domain with a specified security level or the Activate<T>(AddInSecurityLevel, String) overload to include a friendly name for the application domain.

Applies to

Activate<T>(PermissionSet)
