从spl文件中获取份数

Question

我使用以下代码从spl文件中获取副本数量。对于Windows 2008服务器生成的spl文件，没有SpoolerRecordTypes.SRT_DEVMODE。

Private Sub SkipAHeader(ByVal Header As EMFMetaRecordHeader, ByRef SpoolBinaryReader As BinaryReader)

    With Header
        If .nSize <= 0 Then
            .nSize = 8
        End If
        If .iType = SpoolerRecordTypes.SRT_JOB_INFO Then
            Dim JobInfo() As Byte
            JobInfo = SpoolBinaryReader.ReadBytes(.nSize)
            SpoolBinaryReader.BaseStream.Seek(.Seek + .nSize, SeekOrigin.Begin)
        ElseIf .iType = SpoolerRecordTypes.SRT_EOF Then
            '\\ End of file reached..do nothing
        ElseIf .iType = SpoolerRecordTypes.SRT_DEVMODE Then
            '\\ Spool job DEVMODE
            Dim _dmThis As New DevMode(SpoolBinaryReader)
            _Copies = _dmThis.Copies
            SpoolBinaryReader.BaseStream.Seek(.Seek + 8 + .nSize, SeekOrigin.Begin)
        ElseIf .iType = SpoolerRecordTypes.SRT_PAGE Or .iType = SpoolerRecordTypes.SRT_EXT_PAGE Then
            '\\ 
            Call ProcessEMFRecords(Header, SpoolBinaryReader)
        ElseIf .iType = SpoolerRecordTypes.SRT_EOPAGE1 Or .iType = SpoolerRecordTypes.SRT_EOPAGE2 Then
            '\\ int plus long
            Dim EOPAGE() As Byte
            EOPAGE = SpoolBinaryReader.ReadBytes(.nSize)
            If .nSize = &H8 Then
                SpoolBinaryReader.BaseStream.Seek(.Seek + .nSize + 8, SeekOrigin.Begin)
            End If
        ElseIf .iType = SpoolerRecordTypes.SRT_UNKNOWN Then
            SpoolBinaryReader.BaseStream.Seek(.Seek + 4, SeekOrigin.Begin)
        Else
            SpoolBinaryReader.BaseStream.Seek(.Seek + .nSize, SeekOrigin.Begin)
        End If
    End With

End Sub
