Public Function ConvHex2Dec(ByVal sInp As String) As Long
    Dim nRet As Long
   
    If Len(sInp) > 8 Then
        MsgBox "Too long"
    Else
        nRet = Val("&H" & sInp)
        If nRet < 0 And Len(sInp) < 8 Then
            While Len(sInp) < 7
                sInp = "0" & sInp
            Wend
            nRet = Val("&H8" & sInp) And &H7FFFFFFF
        End If
    End If
   
    ConvHex2Dec = nRet
End Function
