Used for workspace persistence, for example, for remembering window positions.

Namespace: Microsoft.VisualStudio.Shell.Interop
Assembly: Microsoft.VisualStudio.Shell.Interop (in Microsoft.VisualStudio.Shell.Interop.dll)

Syntax

'Declaration
Function GetCanonicalName ( _
    itemid As UInteger, _
    <OutAttribute> ByRef pbstrName As String _
) As Integer
'Usage
Dim instance As IVsUIHierarchy
Dim itemid As UInteger
Dim pbstrName As String
Dim returnValue As Integer

returnValue = instance.GetCanonicalName(itemid, _
    pbstrName)

int GetCanonicalName(
    uint itemid,
    out string pbstrName
)

int GetCanonicalName(
    [InAttribute] unsigned int itemid, 
    [OutAttribute] String^% pbstrName
)

abstract GetCanonicalName : 
        itemid:uint32 * 
        pbstrName:string byref -> int

function GetCanonicalName(
    itemid : uint, 
    pbstrName : String
) : int

Parameters

itemid
Type: System.UInt32
[in] Identifier of the hierarchy item. For a list of itemid values, see VSITEMID.

pbstrName
Type: System.String%
[out] Pointer to the canonical name of the hierarchy item.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Implements

IVsHierarchy.GetCanonicalName(UInt32, String%)

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsUIHierarchy::GetCanonicalName(
   [in] VSITEMID itemid,
   [out] BSTR *pbstrName
);

A hierarchy is an object that contains many items, but does not necessarily contain an object for each of those items. Thus, to get information about any of the hierarchy items, you need to query the hierarchy object for that information. The item identifier (itemid) is used to identify the requested item in that query. Using the GetCanonicalName method, you pass in the itemid and the canonical name is returned. The canonical name is a unique name used to distinguish a particular item in the hierarchy from every other item in the hierarchy.

Canonical names do not change between sessions of the environment, but item identifiers do. Use this method to manage workspace persistence, such as remembering window positions.

Hinweis

The environment typically calls this method, but it can be called by anyone with a hierarchy object and a particular item identifier.

Use ParseCanonicalName to determine an item identifier (item ID), given the canonical name for an item.
