National Instruments PC-OPDIO-16 Manuale Utente

This section assumes that you will be using the Microsoft Visual Workbench to manage your
code development.

For Windows programs in general, remember to follow this procedure:

1. Open a project module to manage your application code.

2. Create files of type 

.cpp

 (C++ source code).

3. Create a module definition file, and add it to the project.

4. Create your resources using the 

App Studio

.  After you have created the resources, save

them into an 

.rc

 file and add the 

.rc

 file to the project.

To use the NI-DAQ functions, you must use the NI-DAQ DLL.  Follow this procedure:

1. Create your source file as you would for other Windows programs written in C++, calling

NI-DAQ functions as typical function calls.

2. Prototype any NI-DAQ routines used in your application.  Include the NI-DAQ header file,

which prototypes all NI-DAQ routines, as shown in the following example:

#include "WDAQ_C.H"

3. Add the NI-DAQ import library 

NIDAQ.LIB

 to the project module.

See Special Considerations in the Creating a Windows Application Using Borland C++ and the
Windows SDK section earlier in this chapter.

For Windows programs in general, remember the following points:

1. Turbo Pascal for Windows 1.0 and 1.5 users:  Create files of type 

.pas

 (Pascal source

code), including the Windows object units 

WObjects

, 

WinTypes

, and 

WinProcs

.

Turbo Pascal 7.0 users:  Create files of type 

.pas 

(Pascal source code), including the units

OWindows

, 

ODialogs

, 

WinTypes

, and 

WinProcs

.

2. Create your resources using the Borland Whitewater Resource Toolkit and save the resources

into a 

.res

 file.  You must add this resource to the executable file by using the 

{$R ...}

compiler command.
