实时曲线绘制例程 二维曲线 动态显示-Real-time curve drawing routine two-dimensional curve of dynamic display

MFC实现对自定义绘图的拖拽处理,单文档客户区进行绘图。图形的拖拽处理主要集中在以下三个函数：void OnLButtonDown(UINT nFlags, CPoint point);void OnMouseMove(UINT nFlags, CPoint point);void OnLButtonUp(UINT nFlags, CPoint point);

本源程序仅仅是模仿千千静听界面的源码，并没有音频文件解码的程序，而且少一个皮肤的库文件，可以另外下载，对界面有兴趣的可以研究一下-The source code is only to imitate TTPlayer interface source code, there is no audio file decoding process, but one less skin library file, you can also download the interface may be interested in study

一个多才多艺的五通道 DMA 控制器是系统中可用，访问 XDATA 内存使用的内存 空间，并因此有权访问所有物理内存。每个通道 （触发器、 优先级、 传输模式，解决 模式、 源和目标的指针和转移计数） 与 DMA 描述符，可以配置 位于内存中的任意位置。许多硬件外设 （AES 核心，闪存控制器，USARTs，计时器， ADC 接口等）可用于与 DMA 控制器高效运行的执行数据传输 单一的 SFR 或 XREG 地址与闪光/SRAM。

有一家叫“周大框”的公司，用金属线为客户定制各种图案的框架。目前，该公司只生产圆、长方形和直角三角形等三种框架，材料有金、银、铜和铂金四种。该公司由店铺、生产车间和材料仓库构成。 店铺负责接受客户的订单。客户除了选择图案的种类、材料和数量外，还要给出图案的规格。其中，圆：半径；长方形：长、宽；直角三角形：两个直角边的长度。 框架的价格主要由加工费和材料费两部分构成。其中，加工费仅与框架的形状有关，而与材料的种类和框架的规格无关；材料费由材料的单价乘以框架的周长而得。框架周长精

一个经典好用的位图控件，添加了滚动条，实现图片大过picture控件时自动显示滚动条，拖动滚动条图片随之刷新。

vc下试图分割的代码-vc attempted to separate code

Using comboboxes in the MFC Grid Control Since I posted my MFC grid control I ve had a lot of requests asking how to use other methods of editing cells in the grid. Ken Bertelson has taken this to the extreme, with his Grid Tree control. For some this was a little too involved, so I ve created a demo project that shows how to replace the default editing with a simple combo box. Previous methods of achieving this required that a new CGridCtrl derived class be created. With the new structure in the 2.X versions of CGridCtrl it s now a lot simpler. -Using comboboxes in the MFC Grid ControlSince I posted my MFC grid control I ve had a lot of requests asking how to use other methods of editing cells in the grid.
