1 Visual BasicfqG magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

Visual Basic in interface design, file operations, multimedia applications, data access, Internet application provides a powerful tool for integrated development environment and software debugging environment is convenient, has the advantages of easy to learn and easy to use and powerful. However, for the development of virtual instrument, the VB in the aspect of data processing and graphic display is less LabWEW. In VB development of industrial measurement and control system application software, often need to treat the measurement signal real-time acquisition, display, and real-time processing, etc. , and VB is not good at in this respect. Therefore, to this kind of application development, is the ideal solution, the VB graphical user interface development and other advantages and LabVIEW advantages in data acquisition, display and processing, complement each other, each other to develop more powerful measurement and control software system. In addition, also useful VB and MATLAB programming development of virtual instrument. There are two main types of the combination of MATLAB and VB way [ 1] 。 One is the introduction in VB MATRIXVB, making the VB can invoke MATLAB functions. The second stage is the file will be written in the MATLAB compiled into VB can call DLL files. By mixed programming, using VB and MATRIXVB, fast, simple to generate virtual instrument, and by calling MATLAB print, text, graphics and other function can gain more operation function [ 1] 。 FqG magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

2 VCfqG magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

VC is a general and powerful editor language, has the incomparable advantage, has now become a mainstream development platform. As a popular visual object-oriented programming software, using the virtual instrument software programming, for many programmers familiar with vc, is a convenient and quick. But in terms of virtual instrument development, due to its own interface controls is not very rich, in many measurement and control software for the user interface has a similar appearance and real instrument cases, using vc implementation often need to tens of thousands of bar code, also often produce efficiency is too low. Fortunately, there are abundant interface controls in LabVIEW many controls available for other programs to share, but also can add external controls in the vc. Thus can realize under the vc environment for programming using LabVIEW controls [ 6] 。 In addition, the use of vc and LabWindows mixed programming also can yet be regarded as a good solution. This will be detailed in the back of the Lab Windows part. Therefore, VC in regard to the development of virtual instrument, often mixed with other development tools for programming can greatly improve the efficiency of programming, reduce the workload, shorten the development cycle, improve the economic benefit.

3 Visual Studio. Magnetic flap | | glass thermometer thermometer NETfqG floating ball | | glass thermometer thermometer two-color thermometer

Visual Studio. NET and. Connected with the. net framework is a good tool for the construction of a web application. But so far there are few separately using Visual Studio. NET to develop virtual instruments. Usually need to use third-party packages to the Visual Studio at the same time. NET advantage into full play. At present there are agilent (package is mainly based on the platform Angilent) T& M packages and Measurement of NI company Studio for Visual Studio. NET, etc. FqG magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

4 c + + BuilderfqG magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

development system usually at the bottom of things, need excellent compatibility and stability, and Visual c + +. And development for the enterprise high-level applications such as database, information management system, and has a relatively tight deadlines, c + + Builder is better. For the development of virtual instrument, the situation of the c + + Builder is similar with VC, besides can independently develop, most of the time also can adopt the method of mixed programming of development. When will it with LabWindows/CVI combined instrument control, data acquisition, which can realize good instrument control and peripheral development capabilities. In the process of mixed programming, c + + Builder call LabWindows/CVI dynamic link library, there are two kinds of explicit and implicit links. The implicit link through the dynamic link library import library file ( 。 1 ib file) The implementation,. 1 ib files in LabWindows/CVI generates the & # 65533; % AfqG magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
