多普达710是SP系统的手机，此程序主要演示在710中操作捕获摄像头数据。这里用到了winbile上的CamSDK，效果不错。感谢作者。若加入视频压缩及网络传送功能则更好。-Dopod 710 is the SP system of mobile phones, the main demonstration of this procedure to operate in the 710 camera to capture the data. Here used the winbile on CamSDK, good results. Thank the authors. If the video compression and network transmission function better.

这是一个SDK程序。本程序跟踪显示鼠标的坐标位置，同时，若有鼠标操作，可在窗口标题栏中显示操作信息，要是在窗口客户区中进行双击，就会在双击位置点上显示位置信息。此外，客户中还有两个位图，当鼠标移动到位图上时，就会改变为自己定义的光标。该程序适合Win32编程初学者，内含大量的中文注释。 -SDK This is a process. This program tracking shows the coordinates of the mouse position, and if the mouse operation, the window title bar shows operating information, if the window area for customers double-click, double-click will be the point location shown on the location information. In addition, customers there are two bitmap, when the mouse movement on the plan in place, they will change their definition of the cursor. The program suitable for beginners Win32 programming, with a lot of Chinese Notes.

输入一个自然数Ｎ（2≤N≤9），要求输出如下的螺旋矩阵，即边长为N*N，元素取值为1至N*N，1在左上角，呈顺时针方向依次放置各元素。 N=3时，相应的矩阵中每个数字位置如下图所示： 1 2 3 8 9 4 7 6 5-Enter a natural number N (2 ≤ N ≤ 9), the requirements are as follows spiral output matrix, that is, edge length of N* N, the element values for the 1 to N* N, 1 in the upper left corner, showing a clockwise direction in order to place the various elements . N = 3, the corresponding figures for the location of each matrix as follows: 123,894,765
