![]() The operating system was Windows 95 and the 32-bit version of Visual Basic 4.0 was used to evaluate ComponentWorks. NI-DAQ 4.8.5 or later for Windows 95 (to use DAQ controls).įor this software review, the test installation computer was a 66-MHz 80486 with 30 MB of memory and a 370-MB hard disk drive. Microsoft Windows 95 operating system (Windows NT soon).ģ2-bit OLE custom control container such as Visual Basic 4.0 (32-bit version). To install and use ComponentWorks, a 33-MHz 80486 or higher PC is required (a 66-MHz 80486 is recommended) with: ComponentWorks does not function as a stand-alone package. Instrument drivers-32-bit DLLs for controlling common GPIB instruments, included only with the full Development System.Īlthough the ComponentWorks’ OLE controls and DLLs are designed for Visual Basic 4.0, they also can be used with many other applications that support OLE controls and DLLs, such as Visual C++, Access and Delphi. The number of controls included in the Analysis Library depends upon the level of the package purchased: Base System, Standard Development System or Full Development System. User interface controls-32-bit OLE controls for data display, including graphs and strip charts, sliders, thermometers, tanks, knobs, gauges, meters, LEDs and switches.Īn Analysis Library-32-bit OLE controls, including functions for statistics, advanced signal processing, windowing, filtering, curve fitting, vector and matrix algebra routines, probability and array manipulation. The ComponentWorks package contains:ĭAQ controls-32-bit OLE controls for analog and digital I/O using National Instruments’ DAQ boards. The combined resources of Visual Basic 4.0 and ComponentWorks control National Instruments’ data acquisition boards (DAQs) as well as the common IEEE 488 instruments. It supports team development, code profiling, remote automation and source control for remote data access. Visual Basic Enterprise Edition is the most advanced of the trio. Visual Basic Professional Edition has the additional capabilities of creating OLE automation servers and compiling 16-bit applications for Windows 3.1. Visual Basic Standard Edition is the primary version, with full support for 32-bit programming. Three versions of Visual Basic 4.0 are available: Standard Edition, Professional Edition and Enterprise Edition. 1 Visual Basic 4.0 lets you take advantage of the more powerful program constructs such as classes, reusable elements and system- level Application Programming Interface calls. Visual Basic contains the power necessary to build complex applications, yet it is relatively easy and simple to learn. Not only is it simple to use, Visual Basic also is powerful enough to create elaborate programs that can rival almost anything that hard-core C++ programmers can put together. Since its introduction, Visual Basic has become one of the most popular ways to create Windows applications quickly and easily. It includes software, a manual, and an extensive online reference for specific information about the properties, methods and events of the OLE controls and the routines of the DLLs.īut first, let’s look at Visual Basic. That’s why we reviewed ComponentWorks Version 1.0 by National Instruments (NI), one of many add-on tool sets available for Visual Basic.ĬomponentWorks is a collection of object linking and embedding (OLE) controls and dynamic link libraries (DLLs) for acquiring, analyzing and displaying data within Microsoft’s Visual Basic 4.0. The electronics industry’s strong emphasis on data acquisition prompts us to look carefully at tools that could make this task easier and simpler.
