Since GUIare basically visual, the best way to learn to use them is by practicingon your systemMost gui systcms usc a mouseas a poinTing device, with whichyou can select areas on the screenfor command execution andmoving from one program toanother. Your mouse may have 2www.door 3 buttons; Maxwell 3D ignoresthe middle button on 3-buttondelsAnsoft products donot usc this button. You canprogram mouse buttons to work in non-standard ways, as you mightwant to if you are left-handed. For simplicity, the left-hand hutton(under your forefinger if you are right-handed) is called the leftbutton, and the one on far right is the right mouse button. You willprobably find the terms intuitive once you use these buttons a fewtimesPoint and click; Right clickTo choose an item with the mouse, first move it on your desk until thearrow cursor is on that item; you are now pointing" at the item. Next,ress and release the left bu tton thlled"clicking " Point-andclick is the most common action you will make with your mouseally, click" refers to a lefise button clickYou can sometimes use your right mouse button to access or entercommands. In the 3d Modeler for instance, a right mouse buttonclick causes a short menu of commands to appear at the moustcursor. Generally, right click "refers to a right mouse button clickDouble-ClickOccasionally you may want to sclect all of thc text in a box,orperform a special lask(such as indicating the end of drawing a linewhile you are using Maxwell 3D. You can do this efficiently byquickly clicking twice with your left mouse button -a doubleDragging objects; Click and HoldWhen you are drawing in the 3D Modeler, you can often use yourmouse to enter objects and move around the screen. Frequently, youwill click the mouse button and hold it down until the next part of thecommand is reached (the object is oved, the next point is enteredand so forth). If you click and hold on the edge of a w indow, you canposition, or drag, the window on your screen.

通过MFC实现学生通讯系统的简单功能如添加，删除，查询，修改

这是前几天刚做的一个图像处理的大作业，给大家分享一下。主要是实现了一些基本的图像处理的功能，并做了一个小界面，很简单。基本功能有图像平滑（邻域平均法）、锐化（拉普拉斯）、二值、灰度化、腐蚀、膨胀、小波分解（只显示近似部分图像）、边缘提取、人脸识别（基于PCA）。 程序有两个，一个事GUI的，一个是人脸识别的（大家自己修改人脸库路径）。论文（word和PDF都有）也在里面，希望对大家能有帮助。
