树状潮流计算程序应用，原理如张尧老师的论文-Tree flow calculation procedure

一个航空订票管理系统，很简单，很方便，C++ MFC 做的，功能不是太强大-nothing

　JAVA以其跨平台的特性深受人们喜爱，而又正由于它的跨平台的目的，使得它和本地机器的各种内部联系变得很少，约束了它的功能。解决JAVA对本地操作的一种方法就是JNI。 　　JAVA通过JNI调用本地方法，而本地方法是以库文件的形式存放的（在WINDOWS平台上是DLL文件形式，在UNIX机器上是SO文件形式）。通过调用本地的库文件的内部方法，使JAVA可以实现和本地机器的紧密联系，调用系统级的各接口方法。 -JAVA characteristics of its cross-platform very popular, and because it is the purpose of cross-platform, making it the local machine to become small internal contact, the functions of its binding. JAVA solution on the local operation is a method of JNI. JAVA through JNI to call native methods, and the local method is based on the form of library files stored (in the WINDOWS platform are on the form of DLL files, in the UNIX machines are SO on the form of a document). By calling the local library file internal methods, so that JAVA and local machine can achieve close contact, call the system-level methods of the interface.

应用背景虚拟仪表具有价格低廉，外观简洁，实用，真实。采用C语言编写过程代码，提供所见即所得的控件进行UI设计。能够有效代替实际仪表。作为嵌入式设备的上位机软件，开发周期短关键技术本软件是一个虚拟仪器的例子，主要实现上位机和下位机的串口通信，传递温度和压力数据，显示在界面上。是一款简洁通用的温度压力测量软件

C# 打印Datagridview 中数据  public GridPrinter(DataGridView objDataGridView, PrintDocument objPrintDocument, bool bCenterOnPage, bool bHasTitle, string sTitle, Font objTitleFont, Color objTitleColor, bool bPaging)     {         dataGridView = objDataGridView;         printDocument = objPrintDocument;         centerOnPage = bCenterOnPage;         hasTitle = bHasTitle;         title = sTitle;         tit

A组 用汇编语言实现：在屏幕上显示： SIN（X）+345*X/67 X=？ REXUILT= 等待输入一个任意的十进制数X（假设每个数不超过三位），计算上述表达式的结果，将该结果显示出来：对于XIN（X）的计算结果要求采用子程序编写，主程序用于输入X和显示结果。 B组： 汇编程序写一个能与PC当前运行的程序进行分时操作的程序，程序的功能是演奏“五星红旗迎风飘扬”。并设置有热键，可随时终止或恢复演奏。 C组： 用汇编程序编程编写一个动画程序：有一架飞机在显示屏幕的上方，从左至右，忽高忽地，周而复始的飞行，屏幕下方设有一门高射炮，该炮可人工控制左右移动，人工控制空格键发射炮弹，炮弹命中飞机后，声光大作。（要求使用图形显示方式） -A group Using assembly language to achieve: on the screen: SIN (X)+345* X/67 X =? REXUILT = Waiting for input an arbitrary decimal number X (the assumption that the number of not more than three each), calculated the results of the above expression, the results are displayed: For XIN (X) requires the calculation of the results of the preparation subroutine, main program for Enter the X and the result will be displayed. B: Assembler to write a PC currently running with the process time-sharing operating procedures, procedures for the function is to play "five-star red flag fluttering in the wind." And set up hotkeys, may terminate

该小程序是用C编写的用于解线形方程组，算法才用的是消元法。学习之用。-the small procedure is used for the preparation of C Solutions linear equations, the algorithm will use the elimination method. Learning.
