Public Function FindCommonSelectedHierarchy (grfOpt As UInteger, ByRef lppCommonUIH As IVsUIHierarchy) As Integer

Parameters

grfOpt: UInt32

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

lppCommonUIH: IVsUIHierarchy

[out, retval] Common IVsUIHierarchy interface for the selected hierarchy.

Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell.idl:

   [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.
