本例展示了怎样将mschart控件作出的图形拷贝到剪贴板中的方法.非常实用!(the cases demonstrate how to control the mschart graphics copied to the clipboard. Very real use!)

声卡数字频率计 该程序是标准的Windows界面,界面友好,以黑色背景红色大号字体显示频率值,具有醒目,程序简洁和测量精度高的特点()

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)

MFC 小型试验 画出圆角矩阵 线段等在选定的边界内移动鼠标(Small-scale test matrix to draw rounded MFC segments, etc. within the boundaries of the selected move the mouse)

说明：  一种类似 vc++6.0MSDN风格的界面，和数据库结合，可实现搜索、索引、目录等功能，很实用，(vc 6.0MSDN a similar style of interface, and databases, to search, index, table of contents and other functions, is very practical,)

说明：  该程序实现了图的先序、后序遍历和拓扑排序等，而且是界面输出。(the program to achieve the plan's first sequence, after the preorder and topological sorting, but it is the output interface.)

用vb6直接调用excel生成报表，不用导出到excel就可以完成(Generate reports using vb6 direct call excel, do not export to excel can be completed)
