' Example of usage:
'    Dim wInitStatus as Integer, hSumInfo As Integer, bResult As Integer
'    Dim s$, yr%, mon%, dy%, hr%, min%, sec%
'    wInitStatus = SumInfoInit()
'    If wInitStatus <> 0 Then
'       hSumInfo = SumInfoOpenFile("..put your file name here..")
'       If hSumInfo <> 0 Then
'          s$ = String$(256, " ")
'          bResult = SumInfoGetString(hSumInfo, PID_TITLE, s$, 256)
'          bResult = SumInfoGetTime(hSumInfo, PID_LASTSAVED, yr%, mon%, dy%, hr%, min%, sec%)
'          SumInfoCloseFile (hSumInfo)
'       End If
'       SumInfoUninit(wInitStatus)
'    End If
'
' Reasons for failure:
'     SumInfoInit:     out of memory
'     SumInfoOpenFile: out of memory
'                      file not found
'                      file is not an OLE 2.0 structured storage file
'                      file does not contain OLE 2.0 summary info
'                      OLE 2.0 summary info is incorrectly formatted
'     SumInfoGet...  : specified property type is not available
'
