Parameters
pHier
Type: Microsoft.VisualStudio.Shell.Interop.IVsUIHierarchy[in] IVsHierarchy interface to determine the state or appearance of.
itemid
Type: System.UInt32[in] Identifier of the item in the hierarchy. For a list of itemid values, see VSITEMID.
dwStateMask
Type: System.UInt32[in] Mask values used to determine which pdwState values are provided. For a list of dwStateMask values, see __VSHIERARCHYITEMSTATE.
pdwState
Type: System.UInt32%[out, retval] Values taken from the __VSHIERARCHYITEMSTATE enumeration, which were passed in with expf in ExpandItem.
Return Value
Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
