钢琴弹奏程序【VC++编程】(Piano Playing Procedural programming-- VC)

说明：  基于19264的KS0108的stm32的硬件编程(Hardware Programming of STM32 Based on KS0108 19264)

VC++ USB 通用代码，包括通过VID，PID查找 USB设备，以及连接，通讯。(VC++ USB general code)

VC2005通过ADO连接Access2007数据库的简单Demo，系统Vista SP1 + Visual Studio 2005 + Office 2007 !!!(VC2005 connected Access2007 database through ADO simple Demo, system, Vista SP1+ Visual Studio 2005+ Office 2007!!!)

这编码帮着展示图像代表情况，每年学生报告附带图片(This code helps you to show graphical representation for situations like generating annual report for student with its graph. This code creates Pie Chart likewise we can also create Bar Chart. )

C# VTK混合编程，一个学习C#与VTK的入门(C# VTK)

基于.net开发的驾校管理系统，可以直接运行部需要修改配置(.net for school system demo)

本源程序是MC9S08EL32的单片机和VPC3芯片来实现DP从站开发的源程序；(The source code is MC9S08EL32 microcontroller and VPC3 DP slave chip to achieve development of the source )

说明：  qt中提供了QGphicsView，QGraphicsScene，QGraphicsItem，QGraphicsPixmapItem是QGraphicsItem的子类 分辨创建它们的实例：view，scene，item，然后通过各自的方法scene->addItem(item);view->setScene(scene);就可以达到类似下图的效果，想要进一步定制，则要继承QGraphicsItem或QGraphicsPixmapItem，然后重写paint()、boundingRect()等方法，此外如果还想要获取鼠标事件，重写mousePressEvent等事件就好了，注意，一旦重写了mousePressEvent方法，就以为了qt不会再自动处理item的任何press事件了，可以在你重写的mousePressEvent方法中最后添加QGraphicsItem::mousePressEvent(event);解决这个问题，就是说你获取到了鼠标事件，但是依然让qt处理这个鼠标事件。(QGphics View, QGraphics Scene, QGraphics Item and QGraphics PixmapItem are provided in qt. They are subclasses of QGraphics Item. Resolve the instances of creating them: view, scene, item, and then use their respective methods scene - > addItem (item); view - > setScene (scene); you can achieve the effect similar to the figure below. If you want to further customize, you need to inherit QGraphics Item or QGraphics Pixmap Item, and then rewrite paint (), boundingRect () and other methods, and if you want to do so. If you want to get mouse events, rewrite events like mousePressEvent. Note that once you rewrite the mousePressEvent method, you think that QT will no longer automatically handle any press events of item. You can finally add QGraphics Item:: mousePressEvent (event) to your rewritten mousePressEvent method to solve this problem. That is, you get the mouse event, but still let QT handle the mouse event.)
