调用dll文件截取最前端窗口的图像，调用需要等待200ms(Calling DLL file to intercept the front-end image)

说明：  用labview对数据库进行访问链接的介绍和例程，初学者应该具备数据库知识。(Introduction to using labview for database access links and routines, beginners should have database knowledge.)

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.)

labview做的密码登录系统，简单好用(LabVIEW password login system, simple and easy to use)

用labvIEW编写的一个通过ADO对数据库进行添加、删除、更新、连接等操作的通用VI，可以缩短数据库的开发周期(A written in labvIEW of database through ADO connects operations such as add, delete, update, and the general VI, can shorten the development cycle of a database )

在labview主界面中设置多个功能的选择，调用出子界面(realise multi-task selection and call different sub function in the main front panel of Labiview)

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )
