Namespace: Microsoft.VisualStudio.Shell.Interop
Assembly: Microsoft.VisualStudio.Shell.Interop.8.0 (in Microsoft.VisualStudio.Shell.Interop.8.0.dll)

Syntax

'Declaration
Function EnumPresentationNodes ( _
    dwFlags As UInteger, _
    <OutAttribute> ByRef ppEnum As IVsEnumNavInfoNodes _
) As Integer
'Usage
Dim instance As IVsNavInfo
Dim dwFlags As UInteger
Dim ppEnum As IVsEnumNavInfoNodes
Dim returnValue As Integer

returnValue = instance.EnumPresentationNodes(dwFlags, _
    ppEnum)

int EnumPresentationNodes(
    uint dwFlags,
    out IVsEnumNavInfoNodes ppEnum
)

int EnumPresentationNodes(
    [InAttribute] unsigned int dwFlags, 
    [OutAttribute] IVsEnumNavInfoNodes^% ppEnum
)

abstract EnumPresentationNodes : 
        dwFlags:uint32 * 
        ppEnum:IVsEnumNavInfoNodes byref -> int

function EnumPresentationNodes(
    dwFlags : uint, 
    ppEnum : IVsEnumNavInfoNodes
) : int

Parameters

dwFlags
Type: System.UInt32
[in] One of the _LIB_LISTFLAGS values. Specifies a symbol-browsing tool, such as Class View, Object Browser, or Call Browser (only available in C++).

ppEnum
Type: Microsoft.VisualStudio.Shell.Interop.IVsEnumNavInfoNodes%
[out] The IVsEnumNavInfoNodes. Identifies the collection of nodes in the presentation path of the symbol.

Return Value

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

Remarks

COM Signature

From vsshell80.idl:

HRESULT IVsNavInfo::EnumPresentationNodes(
   [in] DWORD dwFlags, 
   [out] IVsEnumNavInfoNodes ** ppEnum
);

A symbol may have several presentation paths but only one canonical path.

The presentation path depends in which symbol-browsing tool the symbol is displayed. It also depends on the position of the symbol relative to other symbols in the hierarchy tree.
