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

Syntax

'Declaration
Function FindCommonSelectedHierarchy ( _
    grfOpt As UInteger, _
    <OutAttribute> ByRef lppCommonUIH As IVsUIHierarchy _
) As Integer
'Usage
Dim instance As IVsUIHierarchyWindow
Dim grfOpt As UInteger
Dim lppCommonUIH As IVsUIHierarchy
Dim returnValue As Integer

returnValue = instance.FindCommonSelectedHierarchy(grfOpt, _
    lppCommonUIH)

int FindCommonSelectedHierarchy(
    uint grfOpt,
    out IVsUIHierarchy lppCommonUIH
)

int FindCommonSelectedHierarchy(
    [InAttribute] unsigned int grfOpt, 
    [OutAttribute] IVsUIHierarchy^% lppCommonUIH
)

abstract FindCommonSelectedHierarchy : 
        grfOpt:uint32 * 
        lppCommonUIH:IVsUIHierarchy byref -> int

function FindCommonSelectedHierarchy(
    grfOpt : uint, 
    lppCommonUIH : IVsUIHierarchy
) : int

Parameters

grfOpt
Type: System.UInt32
[in] Controls whether this method returns the Solution as the common hierarchy. For a list of grfOpt values, see __VSCOMHIEROPTIONS.

lppCommonUIH
Type: Microsoft.VisualStudio.Shell.Interop.IVsUIHierarchy%
[out, retval] Common IVsUIHierarchy interface for the selected hierarchy.

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 IVsUIHierarchyWindow::FindCommonSelectedHierarchy(
   [in] VSCOMHIEROPTIONS grfOpt,
   [out, retval] IVsUIHierarchy** lppCommonUIH
);

The UI hierarchy window contains a parent chain of hierarchies. If you select two or more nodes that reside in the same hierarchy, this method returns the parent of that hierarchy. Similarly, if you select nodes that reside in two different hierarchies, this method returns the parent of those two hierarchies.
