Solution:

Here are some guidelines from our driver manual. How to compile in Borland C++ Builder, Borlanc C++ V5.0 or above? (1) Please new a Project which you should set it in using class library, don't use OWL. (2) Import \Program Files\Advantech\Examples\BC\LIB\ADAPIBC.LIB for Borland C++ or \Program Files\Advantech\Examples\BCB\LIB\ADAPIBC.LIB for Borland C++ Builder. The Header Libraries for BC++/BC++ Builder are the same, but it is different from the .LIB file for VC++. If you want to call to any DLL by BC++/BC++ Builder, you can apply IMPLIB utility to create new .LIB files. Syntax: IMPLIB [options] libname[.lib] dllname[.dll] Example: (1) IMPLIB?C:\Program Files\Advantech\Adsapi\Examples\BC\LIB \ADSAPIBC.LIB?C:\WinNT\ADSAPI32.DLL (2) IMPLIB?C:\Program Files\Advantech\Adsapi\Examples\BC\LIB \ADSAPIBC.LIB ?C:\Windows\ADSAPI32.DLL (3) Add your filename of source code into this project. (4) You configure the Data Alignment to Quad Word (8-Byte) in the Processor item of 32-bit Compiler setup of Project Options. Because the default Data Alignment of Visual C++, Visual Basic and Delphi are in Quad Word (8-Byte), you don have to change the configuration in those programming language environment. Attached are two BCB examples, one for analog input with interrupt trnasfer and the other for analog output.
