.gif "Static member") |
GetGlobalService | Gets a service proffered globally by Visual Studio or one of its packages. This is the same as calling GetService() on an instance of a package that proffers no services itself. |

|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
Initialize | Called when the VSPackage is loaded by Visual Studio. |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
OnLoadOptions | Invoked by the package class when there are options to be read out of the solution file. |
|
OnSaveOptions | Invoked by the Package class when there are options to be saved to the solution file. |
|
ParseToolboxResource(TextReader, Guid) | Parses an embedded text resource of appropriate format for information about which items should be added to the Toolbox. |
|
ParseToolboxResource(TextReader, ResourceManager) | Parses an embedded text resource of appropriate format for information about which items should be added to the Toolbox. |
|
QueryClose | Called to ask the package if the shell can be closed. |
|
RegisterEditorFactory | Registers an editor factory with Visual Studio. |
|
RegisterProjectFactory | Registers a project factory with Visual Studio. |
|
ShowOptionPage | Displays a specified tools options page. |
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |

Events
| Name | Description | |
|---|---|---|

ToolboxInitialized | Event generated whenever Visual Studio initializes its Toolbox. |
|
ToolboxUpgraded | Event generated whenever Visual Studio upgrades its Toolbox. |

Remarks
The Package class provides a managed implementation of several of the most useful VSIP interfaces. You can create the basic functionality of a VSPackage with relatively little code by deriving from the Package class, overriding some of its methods, and attaching registration attribute classes. The Package class does not provide direct registration support, but it can use attribute classes to supply the necessary registration information to external tools such as RegPkg.exe.
The Package class offers the following services by default. (You can replace them by asking the VSPackage for IServiceContainer, removing them, and adding your own services in their place.)
Package
The package offers itself as a service.
-
Provides the ability to add and remove services. Any service added with "promote" set to true is proffered to Visual Studio through IProfferService. This makes the service global to all VSPackages within Visual Studio. (This service is available only if the VSPackage has already been loaded.)
In addition to these services, Package uses the service architecture of Visual Studio to provide access to any service available through the global service provider.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
