Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.

这是一个简单地使用WinSock传输文件的工具,分为服务端和客户端,先抛一块砖。(This is a simple way to transfer files using the WinSock tool is divided into server and client, first throw a brick.)
实时HTTP下载控件 一个实时显示进度条的HTTP下载控件,使用WINSOCK,支持断点续传。速度。使用mschart控件,计量比较准确.(HTTP download real-time control of a real-time display of HTTP download progress bar control, the use of WINSOCK, Supporting HTTP. Speed. MSChart use controls, a more accurate measurement.)
招聘评分系统,适合用在企业招聘,现在招聘中!(Recruitment scoring system, suitable for use in corporate recruitment, recruitment now!)
界面清爽VB版高级专业防火墙 Ver 2.0.3 源代码,非常棒,强烈推荐!(VB version of the interface refreshing senior professional firewall Ver 2.0.3 source code, great, highly recommended!)
说明: vb做的局域网监控系统,同学的毕业设计,研究winsock很有用(vb to do the LAN monitoring system, students graduating from design, research useful winsock)
用API函数写的winsock控件源代码.(API function to use the winsock control to write the source code.)
这是用VB编辑的点对点通讯工具,只要双方拥有IP地址,就可以连接通讯.可以用于Internet,局域网等网络中.()
这是VB6.0上MSDN的例子,不过我做了稍微改动,能实现输入任意的IP地址,实现与其通信的目的(This is a VB6.0 example on MSDN, but I make a slight alteration can realize arbitrary input IP address, the realization of the purpose of communication)
自动计算上网的时间,下载看了你就知道是什么东西了,反正这在也没法给你说请楚.(Automatic calculation of time online, download saw you know what, and anyway it would not be able to tell you please Chu.)
windows 终端服务查询登录信息等。 可用于远程桌面二次开发,使用RDP协议的远程连接等。(windows Terminal Services query log information. Remote Desktop can be used for secondary development, the use of RDP protocol, such as remote connectivity.)
ghost之后自动修改计算机名和工作组,并且可以根据mac地址来制定计算机名(ghost after automatic modification of computer and the work group, and under the mac address to develop computer name)
中频感应加热以其加热效率高、速度快,可控性好及易于实现机械化、自动化等优点,已在熔炼、铸造、弯管、热锻、焊接和表面热处理等行业得到广泛的应用。 本设计根据设计任务进行了方案设计,设计了相应的硬件电路,研制了20KW中频感应加热电源。 本设计中感应加热电源采用IGBT作为开关器件,可工作在10 Hz~10 kHz频段。它由整流器、滤波器、和逆变器组成。整流器采用不可控三相全桥式整流电路。滤波器采用两个电解电容和一个电感组成Ⅱ型滤波器滤波和无源功率因数校正。逆变器主要由PWM控制器SG3525A控制四个IGBT的开通和关断,实现DC-AC的转换。 设计中采用的芯片主要是PWM控制器SG3525A和光耦合驱动电路HCPL-316J。设计过程中程充分利用了SG3525A的控制性能,具有宽的可调工作频率,死区时间可调,具有输入欠电压锁定功能和双路输出电流。由于HCPL-316J具有快的开关速度(500ns),光隔离,故障状态反馈,可配置自动复位、自动关闭等功能,所以选择其作为IGBT的驱动。 对原理样机的调试结果表明,所完成的设计实现了设计任务规定的基本功能。此外,为了满足不同器件对功率需要的要求,设计了功率可调。这部分超出了设计任务书规定的任务。(induction heating with high heating efficiency, speed and good controllability and easy to mechanization. the advantages of automation, in melting, casting, bending, forging, welding and surface heat treatment and other industries have been widely employed. According to the design tasks for the design of the program design, design corresponding to the hardware circuit, Development of 20 KW induction heating power. The design of induction heating power IGBT used as a switching device, which can work in 10 Hz- 10 kHz frequency band. It consists of rectifier, filter, and the inverter components. Controlled Rectifier not use the entire three-phase bridge rectifier circuit. 2 filter used an electrolytic capacitor and inductor components II-type filter and passive PFC. Inverter mainly by the PW)
一个很不错的网络聊天程序,分为客户端和服务段,总体的功能很不错的(a very good network chat procedures, and is divided into client services, the overall function of very good)
一个通过网络高速传输文件的控件: 具有以下特点 1.有高速数据传输功能,超过了Winsock控件的吞吐量 2.入校验功能,满足大数据包的收发,理论上不限数据尺寸 3.加入防错代码,提高了接口鲁棒性(through a network of high-speed transmission of documents, the controls : one with the following features. A high-speed data transmission functions Controls over the throughput of Winsock 2.- Check function and meet large data packet transceiver, Theoretically Open-data size 3. to prevent the wrong code, improve the robustness Interface)
说明: VB 例程序讲解 、局域网聊天程序 二、可以换肤的窗体 三、richtext实现的文本编辑器 四、用OLE实现文件拖放 五、窗体卸载时弹出确认对话框 六、让控件大小随窗体改变而改变 七、拖动无标题栏窗体 八、在打开文件对话框中选择多文件 (VB procedures on cases, two LAN chat program, the Eurocargo Form 3, the realization richtext text editor 4, OLE files with drag-and-drop 5, Form unloading pop confirmation dialog box six, with the size controls Form change of seven, dragging Untitled Form 8 column, in fighting to open a file selection dialog many documents)
