A calling method of dynamic link library based on labview

Abstract

The invention discloses a calling method of a dynamic link library based on LabVIEW, including: determining the position of the DLL file of the dynamic link library, the function prototype, and the parameters and types of the function; selecting the method of calling the function; using the call library function node CLF in LabVIEW Extract the functions in the DLL file; configure the functions in the DLL file based on the LabVIEW specification; input the name of the called function to obtain the formal parameter type and return value type of the function based on the LabVIEW configuration; combine the nodes in the CLF and their data types Connect the corresponding attribute nodes of the nodes to complete the code design using LabVIEW. The technical scheme of the present invention uses CLF in LabVIEW to call dynamic link library functions produced by other languages, thereby completing the work that LabVIEW cannot do, and improving the efficiency of program development.

Description

A calling method of dynamic link library based on LabVIEW technical field The invention relates to a dynamic link calling method. More specifically, it relates to a calling method of a dynamic link library based on the graphical programming language LabVIEW. Background technique A dynamic link library is an executable code and data module connected at runtime. It is an important part of the Microsoft Windows system operating system. It is a special and widely used function library. Although the dynamic link library DLL is not an exe file, it is a Windows executable file. A DLL consists of executable modules that provide data, code, and resources to a process. Unlike statically linked libraries that are used at compile time, dynamic linked libraries are independent of the executable that activates them, and address translations for calls are resolved at load time. Compared with the static link library, no matter how many programs are designed by the dynamic link library,...

Problems solved by technology

However, LabVIEW also has deficiencies, such as not being good at completing a large amount of data processing tasks; the ability to implement low-level operations is not strong, etc.
