    pobName : VSOBNAVNAMEINFONODE[], 
    fDontUpdate : int, 
    pfMatchedName : int, 
    pIndex : uint[]
) : int

Parameters

pobNav
Type: array<Microsoft.VisualStudio.Shell.Interop.VSOBNAVIGATIONINFO2[]
[in] Specifies navigation information. Values are in a VSOBNAVIGATIONINFO2 structure.

pobName
Type: array<Microsoft.VisualStudio.Shell.Interop.VSOBNAVNAMEINFONODE[]
[in] Specifies the name of the node of interest. Values are in a VSOBNAVNAMEINFONODE structure.

fDontUpdate
Type: System.Int32
[in] Flag indicating do not update.

pfMatchedName
Type: System.Int32%
[out] Pointer to a flag indicating a matched name was found.

pIndex
Type: array<System.UInt32[]
[out] Pointer to the index of the located item.

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 vsshell.idl:

HRESULT IVsObjectList::LocateNavigationInfo(
   [in] VSOBNAVIGATIONINFO2 *pobNav,
   [in] VSOBNAVNAMEINFONODE *pobName,
   [in] BOOL fDontUpdate,
   [out] BOOL *pfMatchedName,
   [out] ULONG *pIndex
);

When an object has been selected in Object Browser or Class View, and the environment must redraw the view as a result of a sort or expansion, a path back to the selected item must be maintained. The environment will call GetNavigationInfo for the selected object, and each of its parents, ascending the tree until the root node is reached. The environment can then descend the tree, with calls to LocateNavigationInfo to step down through the nodes of the tree list. The VSOBNAVIGATIONINFO2 structure contains the GUID and name of the library. The pobName parameter is a pointer to a VSOBNAVNAMEINFONODE structure containing the name and type of the item of interest. When you find the requested name, set pIndex to the appropriate value for the item, and set pfMatchedName to true. If fDontUpdate is set, and you can't locate the requested item, return E_FAIL. If fDontUpdate is not set and you can't locate the requested item, return pIndex as nulla null reference (Nothing in Visual Basic), and the environment will regenerate the object list.
