本源码主要功能，是对互联网上的google 地图 API 编程，放大，缩小，平移地图，并在地图上定位定位给定点经度，纬度的位置。(The main source function is to google maps on the Internet API programming, zoom in, zoom out, pan the map and locate locate a given point on the map longitude and latitude of the location.)

使用 VC++ 调用微软蓝牙 API 函数的示例代码。可以使用 VC++6.0 至 VC++2010 编译代码。(Using VC++ call Microsoft Bluetooth API sample code. You can use VC++6.0 to VC++2010 compiled code.)

编写程序，实现基于ARP协议获取本局域网内全部活动主机MAC地址与IP地址对应关系列表，要求使用Winpcap，手动封装ARP数据包，并实现ARP响应数据包的接收和解析。(programming, ARP-based LAN access to the activities of all MAC address and IP address correspondence list, require the use of Winpcap, manual Packaging ARP packets, and achieve ARP response data packet reception and analysis.)

this is a source code to help you to construct a poly font on you program. that is good for 3d paint.

要求及背景 工作需要，要在一个Form里面实现一个实时预览的picturebox图像，由于picturebox可能会遮挡到其后面的画面，所以要求picturebox可以由用户自行拖拽，类似于悬浮框。 原理说明 在网上兜了几圈之后，决定用三段代码实现。首先要注册鼠标的三个事件：移动、鼠标左键按下、鼠标左键抬起，当然，都是在picturebox上的动作。注册三个事件后，即可以在三个对应的事件函数里面实现拖拽。(Amplification, reduction and translation of images under WPF)

说明：  一个简单的蓝牙HC05与51单片机通信。(it`s an easy bluetooth project based on stc89c52 and keil u4,for the communication between bluetooth and MCU.)
