(利用GIF_LZW算法实现的)网络图片传输 技术特点 ~~~~~~~~ 一、使用TCP协议传输数据。理由:稳定性好。 二、使用字节数据流进行传输,理由: A:VB的String存在自动Unicode转换问题,影响速度; B:可以直接发送8位字节数据,不需要使用Base64编码,从而减少了编码时间。 三、使用GIF-LZW压缩算法压缩图像。理由: A:行程编码、Huffman压缩算法压缩率太低; B:JPEG压缩算法需要太多位运算,且运算量大(有专门MMX优化算法),不利于VB实现; C:GIF-LZW压缩算法压缩率较好,且我已想出VB语法下高效GIF-LZW压缩/解压算法。 四、使用“有序抖动”算法进行 色彩量化。理由:“有序抖动”处理的结果具有一定规律性,有助于LZW类算法压缩。-(using GIF_LZW algorithm) picture transmission network ~~~~~~~~ a technical features, the use of TCP to transmit data. Reason : good stability. Two, the use of byte data stream for transmission, reasons : A : VB String exist automatically Unicode conversion, the impact speed; B : can directly send eight bytes of data and do not need to use Base64 encoding, thereby reducing the coding time. 3, the use of GIF- LZW compression algorithm for image compression. Reason : A : itinerary coding, Huffman compression algorithm compression rate is too low; B : JPEG compression algorithm needs much-bit computing, and large amount of computation (with MMX spe

RMI(java 远程方法调用):此例子实现了客户端程序通过远程接口向服务器程序发出计算请求,服务器程序调用了一个计算方法,并把结果返回给客户端,这样便达到分布式计算的效果。上传文件里有详细的部署和使用说明,在win2000上测试通过。-RMI (Java Remote Method Invocation) : this example to achieve the client interface to the remote server computing issued request, the server calls a calculation method and the results back to the client, so as to achieve the effect of distributed computing. Upload file are detailed in the deployment and use in WIN2000 on the test.

一款功能较为完善的网络防火墙
Hello !
What is SibairWall ?
This a FireWall (a littke) in Visual Basic.
The possible functions are :
- See the currents open ports on your computer
- Detect the possible intrusions by the most important Trojans !
(red light and attack list)
- Save the attacks to a log
- View the network rate in the systray
you can update the delay of the scan port in the parameters options.
If you re making some good modifications, please send them to me :
sibairmaster@aol.com
