一个VC++下拉字体预览框，像Word的字体选择功能一样，鼠标点击下拉框的时候，下拉框中的字体名称显示的样式就是该字体的样式，用户选择哪种字体一目了然，方便了用户操作。 (A VC++ drop-down box font preview, font selection function as the Word, like drop-down box when a mouse click, drop-down box displays the name of the style of the font is the font style, font at a glance the user choose which to facilitate the user.)

计算机图形学重要参考。对理解OpenGL和D3D的渲染过程有重要帮助。(Computer graphics is a vast field that is becoming larger every day. It is impossible to cover every topic of interest, even within a specialization such as CG rendering. For many years, Noriko Kurachi has reported on the latest developments for Japanese readers in her monthly column for CG World. Being something of a pioneer herself, she selected topics that represented original and promising new directions for research. Many of these novel ideas are the topics covered in The Magic of Computer Graphics. Starting the basic behavior of light, the first section of the book introduces the most useful techniques for global and local illumination using geometric descriptions of an environment. The second section goes on to describe image-based techniques that rely on captured data to do their magic. In the final section, the author looks at the synthesis of these two complementary approaches and what they mean for the future of computer graphics.)

说明：  项目任务 在单链表类中增加一个功能erase(x, y), 删除表中所有值在 [x, y] 之间的结点。假设链表中结点数值类型是整形，要求编程返回删除相应结点后的链表长度和链表元素。 输入描述 第一行输入链表List的结点元素值，元素之间用空格间隔，且均为int类型； 第二行输入为x和y，分别表示需要删除结点元素的最小值和最大值。 输出描述 第一行输出删除相应结点后链表的长度； 第二行输出删除相应结点后链表的所有元素，元素之间用空格间隔。若无剩余元素，输出null。(Project tasks A function erase (x, y) is added to the class of single linked list to delete all nodes whose values are between [x, y]. Assuming that the numerical type of the node in the linked list is plastic, the program is required to return the length and elements of the linked list after deleting the corresponding nodes. Enter a description In the first line, enter the node element values of the linked list list, with spaces between the elements, and all of them are of type int; In the second line, input X and y to indicate the minimum and maximum values of node elements to be deleted. Output description The first line outputs the length of the linked list after deleting the corresponding node; The second line outputs all the elements of the linked list after deleting the corresponding nodes, with space between the elements. If there are no remaining elements, null is output.)

说明：  labview多功能采集系统，各功能全面(LabVIEW multi-function acquisition system, all functions are comprehensive)
