The UIContextGuids type exposes the following members.


  Name Description
Public method Equals Determines whether the specified object is equal to the current object. (Inherited from Object.)
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 Serves as the default hash function. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)



  Name Description
Public fieldStatic member CodeWindow Specifies a context in which a code window currently has focus.
Public fieldStatic member Debugging Specifies a context in which debugging is active.
Public fieldStatic member DesignMode Specifies a context where the editor is in design mode.
Public fieldStatic member Dragging Specifies a context that occurs while dragging items in Solution Explorer.
Public fieldStatic member EmptySolution Specifies a context in which an empty solution has been loaded.
Public fieldStatic member FullScreenMode Specifies a context that is active when Visual Studio is in full screen mode.
Public fieldStatic member NoSolution Specifies a context in which no solution is loaded.
Public fieldStatic member SolutionBuilding Specifies a context in which a project or solution is currently being built.
Public fieldStatic member SolutionExists Specifies a context in which a solution has been loaded.
Public fieldStatic member SolutionHasMultipleProjects Specifies a context in which a loaded solution contains more than one project.
Public fieldStatic member SolutionHasSingleProject Specifies a context in which a loaded solution contains a single project.



A command context indicates a particular state Visual Studio is in, for example, a solution is building or debugging is active. Multiple contexts can be active at the same time, for example, a solution is loaded and the solution has multiple projects.

As contexts change, notifications are sent out to parties that have registered themselves with the SVsShellMonitorSelection service (see the AdviseSelectionEvents method). It is also possible to request the state of any context using the methods in the IVsMonitorSelection interface, which in turn is obtained from the SVsShellMonitorSelection service.

VSPackages that have user interface (UI) elements can associate those UI elements with particular command contexts. When those contexts become active or inactive, the VSPackage's associated UI elements are automatically activated or deactivated as well. The VSPackage associates UI elements to the command contexts using the Visual Studio Command Table (.vsct) file that is part of the VSPackage. For more information about .vsct files, see Visual Studio Command Table (.Vsct) Files. These command contexts are defined in the context parameter of the VisibilityItem element. For more information, see VisibilityItem Element.

Command contexts are defined in the header files vsshlids.h and vsshell*.h. More information about where they are defined is given in the Remarks sections of the individual contexts.

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.
