VCGIS2

这是一个用VC编写COM的例子，用VB调用，对初学者很有用！(This is an example of vc com, it called by vb,it is useful for leaner!)

说明：  vc++2005入门经典 源代码 visual studio.net 2005 vc++的经典入门书籍源代码(vc++ 2005 Introduction to the classic source code visual studio.net 2005 vc++ classic book Introduction to source code)

在MFC上中点法画圆画直线，DDA算法画直线，计算机图形学实验(Midpoint circle drawing a straight line, draw a straight line of the DDA algorithm)

envi中的波段计算！一般是遥感专业可以选择！(ENVI BAND MATH)

VC++发送带附件邮件程序,使用Smtp发送邮件，不带附件发送版本 main.cpp CSmtp.cpp CSmtp.h base64.cpp base64.h(VC++ program to send mail with attachments, using Smtp send mail without attachments version main.cpp CSmtp.cpp CSmtp.h base64.cpp base64.h)

本源码实现了添加系统用户的功能，如果有此爱好的同志可以根据自己的爱好，添加更加丰富的功能。(Add the source realize the function of system users, if there is such a loving comrades can be according to their own hobbies, to add richer functionality.)

初步的CUDA介绍，CUDA用于加速处理。很好用的CUDA入门教材(Initial introduction of CUDA, CUDA to accelerate processing. Good use of CUDA primer)

通信网络的架设问题 若要在n（≥10）个城市之间建设通信网络，只需要架设n-1条线路即可(With the Dijksra algorithm to network G from source points to the rest of the vertices of the shortest path)

vc可以切换当前系统的输入法。根据注册表中输入法的值来切换(vc can switch the current system' s input method. According to the registry value to switch the input method)

说明：  串口通信，也可实现虚拟串口通信。采用VS2015编程 MFC(Serial communication. It can also realize virtual serial communication.)
