Using the Dynamic Industrial Interface with different programming languages

This chapter provides an overview about how to best utilize the Dynamic Industrial Interface in

various programming languages.

If you experience difficulties calling the Dynamic Industrial Interface functions from your program

ming language, or are using a programming language not covered in this documentation, please

feel free to visit our web-site, to which we will post updated information regarding DII programming

issues. You may also contact our technical support through our website: www.decision.com.tw

10.1. C++

Since the DII DLL was developed using C++, you may easily use it to access Industrial I/O de-

vices. For this purpose, a C++ header file ("USBDII.h") as well as an import library ("USBDII.lib")

are being shipped with the interface library. Make sure that you have installed the development

release, not the retail release, which does not include support programming files. In your C/C++

source code files, just include the "USBDII.h" include file, then you can use any of the functions

provided by the USBDII DLL. Be sure to include the import library "USBDII.lib" during the linking

step of your application. So your applications successfully references the actual interface DLL.

10.2. Visual Basic

Since the Dynamic Industrial Interface is fully 32-bit compliant, only 32-bit versions of Visual Basic

are supported. Specifically, Version 6.0 are tested and supported. If you are using Visual Basic

to access any I/O Devices supported by the USB Dynamic Industrial Interface (USBDII), you can

call the USBDII DLL directly. But before that, you should import them. You may also consult the

Visual Basic sample application for more information about using Visual Basic to access the USB

Dynamic Industrial Interface (USBDII).

11. Technical Support and Feedback

We believe that customer input is the most valuable source for creating successful products. We

continuously update and extend the Dynamic Industrial Interface with new functionality, for specific

devices, for specific applications, to meet your specific needs, and provide supportive products

around the USBDII.
