User Manual

ADC-20/ADC-24 User's Guide 38

5.5

Programming languages

The software installed with your ADC-20 or ADC-24 includes examples for the

following programming languages:

C and C++

Delphi

Excel

LabVIEW

Visual Basic

Agilent-VEE

The example programs are installed in the Examples\ADC20 subdirectory of your

PicoLog installation.

5.5.1

C and C++

The C example program is a generic windows application (it does not use Borland

AppExpert or Microsoft AppWizard). To compile the program, create a new project for

an application containing the following files:

HRDLGui.c (graphical user interface) or HRDL.c (console)

PicoHRDL.lib (Microsoft C) or PicoHRDLbc.lib (for Borland C)

The following files must be in the same directory:

HRDL.h

PicoHRDL.dll

resource.h (required by HRDLGui.c)

HRDLGui.rc (required by HRDLGui.c)

C++

If HRDL.h is included in a C++ program, the PREF0 macro expands to extern "C": this

disables name-decoration (as Microsoft calls it), and enables C++ routines to make

calls to the driver routines using C headers.

5.5.2

Delphi V3

You will need the following files from the SDK:

hrdl.dpr, a complete program that opens the driver and reads values from

channel 1

hrdlfm.pas, required for streaming or single-value data collection

hrdlfm.dfm

The file hrdl.inc contains a set of procedure prototypes that you can include in your

own programs.
