The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser).

A designer verb is a menu command linked to an event handler. Designer verbs are added to a component's shortcut menu at design time. In Visual Studio, each designer verb is also listed, using a LinkLabel, in the Description pane of the Properties window.
The following code example demonstrates how to create DesignerVerb objects and add them to the design-time shortcut menu for a component.
Imports System Imports System.ComponentModel Imports System.Collections Imports System.ComponentModel.Design ' This sample demonstrates a designer that adds menu commands ' to the design-time shortcut menu for a component. ' ' To test this sample, build the code for the component as a class library, ' add the resulting component to the toolbox, open a form in design mode, ' and drag the component from the toolbox onto the form. ' ' The component should appear in the component tray beneath the form. ' Right-click the component. The verbs should appear in the shortcut menu. Namespace VBDesignerVerb ' Associate MyDesigner with this component type using a DesignerAttribute <Designer(GetType(MyDesigner))> _ Public Class Component1 Inherits System.ComponentModel.Component End Class ' This is a designer class which provides designer verb menu commands for ' the associated component. This code is called by the design environment at design-time.
