利用VB开发校园GIS系统，是我一直珍惜好多年的东东，今天拿出来希望与大家一起分享，是一个功能比较全的GIS系统，如果进行稍微的改装，可以直接应用于具体的项目中，更具有学习价值(VB developers to use the campus GIS system, which I always treasure the many years of Dongdong, out today, and we wish to share, is a full-feature comparison of the GIS system, if carried out slightly modified, can be directly applied to specific projects, learn the value of more)

VB开发的正弦波发生程序，可以调幅度和频率(VB Development Program that sine wave, amplitude and frequency can be adjusted)

List Media Player List Media Player is one of the first programs I made. It is simply a way of browsing through your drives and folders to find media files to play - either sound or video. The actual player is on a separate Form, which allows for free resizing.(List Media Player List Media Player is one of the first programs I made.

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.
