最近做了一个类似Windows画图板的小程序，拿来和大家分享一下。功能和界面全部模仿于Windows自带的画图板，界面如截图。功能主要有： 手绘线、简单图形、文字输入、图块拖放、重复撤销、画面缩放、打开保存图片文件，另外为了直接从数据库或者XML中存取图片，另外还提供了从Base64编码存取图片的接口，其他还实现了和画图板同样效果的工具箱及颜料盒。(Recently to do a similar drawing board a small Windows program, use and share with you. Features and interfaces in Windows, bringing all to imitate the drawing board, such as interface screenshot. The main features include: hand-painted lines, simple graphics, text input, drag and drop block, duplicate revoked, screen zoom, open the Save picture files, the other in order to directly from the database or XML access picture also provides a survival from the Base64 encoding Photos from the interface, the other also drawing board and achieve the same effect toolbox and paint boxes.)

VC MFC界面编程 完成了一个类似画板的画图工具，可以画基本图形，填充，设置画笔颜色宽度等(VC MFC programming interface similar to the drawing board to complete a drawing tool to draw basic graphics, fill, set the pen color width)

vc如何动态添加和删除菜单项的源码，可以参考下(vc how to dynamically add and remove menu items of the source code, can refer to)

采用vc++2005编写的程序，主要是关于VC多窗口的界面编程方法。(Introduce the MDI application in vc++2005.)

音乐曲线显示控件及实例演示VB源码,有需要的就下载吧。(Music curve shows controls and VB source code examples demonstrate, there is a need to download it.)

说明：  splash启动界面, 用于系统启动时显示的splash窗口(splash activated interface for system startup splash at the show window)

VTK实验程序，利用VTK开源库实现Marching Cubes等值面提取算法，程序中可修改等值面参数，交互界面实现物体的旋转、缩放，数据文件在工程目录下(VTK experimental procedures, the use of open-source library implementation VTK Marching Cubes isosurface extraction algorithm, the program can be modified isosurface parameters, interactive interface to achieve the object rotation, scaling, data files in the project directory)

本例通过绘制螺旋图案描述了如何用VC++绘制MFC图形程序。适合学习MFC图形编程的初学者学习。(cases by mapping the spiral patterns described how MFC with VC graphics rendering procedures. MFC for learning graphical programming beginners learning.)

说明：  许多现代浮点单元的一项主要体系结构功能，是能够将一个乘法与后面紧跟的加法作为单个运算执 行，且没有中间舍入误差。例如，Intel 的 Itanium 体系结构提供了一些指令，将三元运算 (a*b+c) 、(a*b-c) 和 (c-a*b) 中的每一个都组合为单个浮点指令（分别为 fma、fms 和 fnma）。这些单个 指令都比执行独立的乘法和加法指令快，并且因为没有中间乘法舍入，所以更为精确。该优化可以显 著提高那些含有多个交错乘法和加法运算的函数的速度(many modern floating point unit of a major system structure and function is to be a follow closely behind multiplication and addition of implementation as a single operator, with no intermediate rounding error. For example, Intel's Itanium architecture provides a number of directives to the ternary operator (a* b, c), (a* b-c) and (c-a* b) each have a portfolio to a single floating point instructions (Fullmetal respectively, and fms fnma) . These individual instruction than the implementation of an independent and additive multiplication instructions quickly, and because no middle multiplication into homes, so more precise. The optimization can significantly increase those containing more than staggered multiplication and addition operations function of the speed)

这是MFC控件应用的练习，如按钮、 列表框、进度条等等。 对于新人来说，是很好的练习.(This practice is applied MFC controls such as buttons, list boxes, progress bars and so on. For newcomers, it is good practice.)
