通过输入用户名和密码后登录，实现输入正确和错误提示、登录前禁用并灰显读取按钮、登录后启用读取按钮、读取并显示文本文件内容、加密程序框图查看操作。(By inputting user name and password and login, we can input correct and error prompts, disable and gray display the reading button before login, enable the reading button after login, read and display the contents of text files, and view the encrypted program block diagram.)

说明：  如何制作LabView控件，赖卫国整理，方便可行(How to make labview control, Lai Weiguo collation, convenient and feasible)

利用labview软件编写程序对信号进行功率谱峰分析(The power spectrum peak is analyzed by LabVIEW software.)

基于labview和声卡的数据采集，声卡的双声道模拟输出，信号的采集与存储，信号的功率谱分析(Power spectrum analysis based on labview and data acquisition card, sound card, two-channel analog output signal acquisition and storage, signal)

1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

解决LabVIEW里不能使用数码管字体的方法 用FontCreator软件打开字体，将字体的平台由“Windows Unicode BMP(UCS-2)”改为“Windows Symbol”即可。(Method for solving LabVIEW can not use digital tube font With FontCreator software to open the font, the font platform Unicode BMP Windows (UCS-2) to Symbol Windows can be.)

说明：  用于读取txt文本文件，并显示在labview中(Used to read the numbers in the txt file and display them in LabVIEW)

LabVIEW TCP通信实现远程波形通信,可以进行网络控制传输锯齿波、正弦波等。(LabVIEW TCP communication realizes remote waveform communication. It can carry out network control transmission sawtooth wave, sine wave and so on.)

说明：  labview存储与保存、 EXCEl单元格数据更改与保存(Labview Storage and Preservation EXCEl Cell Data Change and Preservation)
