ngrep strives to provide most of GNU grep s common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes TCP, UDP and ICMP across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands bpf filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

除了上面提到的壓縮方法，你也可以調(diào)用VB的工具M(jìn)akeCab.exe（在VB5\setupkit\kitfil32或VB98\Wizards\PDWizard目錄下）生成.cab文件。先構(gòu)造一個(gè)Directive 文件(*.ddf)，然后使用Shell命令調(diào)用MakeCAB /f excel.ddf就可以生成*.cab文件。關(guān)于Directive 文件的格式，可以參考MSDN Library中的《MakeCAB: A Compression and Disk Layout Tool》一文。

DSP音頻處理示例The benefits of real-time analysis provided by DSP/BIOS are often required in programs that were engineered without it. When the program is not built from the ground up using the DSP/BIOS kernel and real-time analysis features, the lack of familiarity prevents engineers from reaping the benefits of this very powerful tool set, especially in the final stage of development when real-time analysis is needed most. This application note provides an example of the necessary steps required to utilize DSP/BIOS features in order to bring these solutions to bear in an existing application.
