The ProvideToolboxItemsAttribute type exposes the following members.


  Name Description
Public method ProvideToolboxItemsAttribute(Int32) Creates a new instance of ProvideToolboxItemsAttribute which indicates if a class implementing a VSPackage is providing Toolbox items.
Public method ProvideToolboxItemsAttribute(Int32, Boolean) Initializes a new instance of ProvideToolboxItemsAttribute for the specified version.



  Name Description
Public property NeedsCallBackAfterReset Gets or sets whether the ToolboxInitialized event should be raised after each toolbox reset.
Public property TypeId Gets the current instance of this attribute. (Inherited from RegistrationAttribute.)
Public property Version Property returning the version of Toolbox items a VSPackage provides.



  Name Description
Public method Equals Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Returns the hash code for this instance. (Inherited from Attribute.)
Protected method GetPackageRegKeyPath Gets the registry path (relative to the registry root of the application) of the VSPackage. (Inherited from RegistrationAttribute.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttribute When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method Match When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method Register Registers a VSPackage as a Toolbox item provider for specified formats when called by an external registration tool such as regpkg.exe. For more information, see Registering VSPackages. (Overrides RegistrationAttribute.Register(RegistrationAttribute.RegistrationContext).)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Public method Unregister Reverses the changes that the Register method had applied to the registry. (Overrides RegistrationAttribute.Unregister(RegistrationAttribute.RegistrationContext).)


Explicit Interface Implementations

  Name Description
Explicit interface implemetationPrivate method _Attribute.GetIDsOfNames Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method _Attribute.GetTypeInfo Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method _Attribute.GetTypeInfoCount Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method _Attribute.Invoke Provides access to properties and methods exposed by an object. (Inherited from Attribute.)



Attribute Context

Applies to

Classes providing VSPackages by implementing IVsPackage, Package.



Required attributes


Invalid attributes


Apply this attribute to a Package-derived class or a class that implements IVsPackage that is required to enable support for users to drag data objects of this format, provided by the class, onto the Toolbox. This implementing class must handle the drop notifications itself.

This attribute is only used for registration purposes, and does not affect how code behaves at runtime.

Depending on the arguments specified in its constructor, this attribute can indicate that a VSPackage does not provide any Toolbox items. If the attribute ProvideToolboxFormatAttribute is added to a class to indicate that it provides Toolbox items, one or more instances of ProvideToolboxFormatAttribute must also be added.

This attribute uses ProvideToolboxFormatAttribute to register a VSPackage as providing Toolbox items of a given format.

If this attribute specifies that Toolbox items are provided, the VSPackage must handle the ToolboxInitialized and ToolboxUpgraded events.

Any VSPackage using this attribute must provide a handler for the ToolboxInitialized and ToolboxUpgraded events.


In the example below, the attributes applied to the class MyPackage indicates that it supports version 1 of Toolbox items of with two clipboard formats "CF_XMLCODE" and "InPlaceMenuEditorMenu".

    [ProvideToolboxItems(true, 1)]
    internal sealed class MyPackage : Package

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
