Remarks
COM Signature
From vsshell.idl:
HRESULT IVsTrackSelectionEx::OnSelectChangeEx(
[in] IVsHierarchy *pHier,
[in] VSITEMID itemid,
[in] IVsMultiItemSelect *pMIS,
[in] ISelectionContainer *pSC
);
Project-type windows call OnSelectChangeEx to alert the environment to a change in the active window and the current selection. The environment uses the pHier and itemid parameters to update the Solution Explorer window if necessary. The pMIS parameter provides access to a multiple selection and the pSC parameter provides access to a single selection.
