Universal Library User's Guide Universal Library Description and Use

If your processor is less than a 150 MHz Pentium and you need an acquisition speed in excess of 200 kilohertz

(kHz), use the NOCALIBRATEDATA option to a turn off real-time software calibration and save CPU time. After

the acquisition is run, calibrate the data with cbACalibrateData().

Visual Basic for Windows

To use the Universal Library with Visual Basic, include the Universal Library declaration file CBW.BAS in

your program. Include the file as a module in the project, or include it by reference inside those Forms which

call into the Universal Library. Once the declarations for the Universal Library have been added to your

project, call the library functions from any Form's event handlers.

For Visual Basic 6.0 and older, Windows memory buffers cannot be mapped onto arrays. As a consequence,

the cbWinArrayToBuf() and cbWinBufToArray() functions must be used to copy data between arrays and

Windows buffers.

Example:

Count = 100

MemHandle = cbWinBufAlloc (Count)

cbAInScan (......, MemHandle,...)

cbWinBufToArray (MemHandle, DataArray(0), 0, Count)

For i = 0 To Count

Print DataArray(i)

Next i

cbWinBufFree (MemHandle)

Visual Basic example programs

A complete set of Visual Basic example programs is included in the VBWIN folder of the Universal Library

installation directory. Each program illustrates the use of a Universal Library function from within a Visual

Basic program. The .FRM files contain the programs, and the corresponding .VBP files are the project files

used to build the programs for Visual Basic.

Microsoft Visual C++

To use the Universal Library with MS Visual C++, include the Universal Library header file CBW.H in your

C/C++ program and add the library file CBW32.LIB to your library modules for linking to the CBW32.DLL.

Microsoft Visual C++ example programs

The CWIN folder of the Universal Library installation directory contains three sample programs - Wincai01,

Wincai02 and Wincai03. Each program is an example of a simple C program that calls a few of the Universal

Library functions from a Windows application. Use the .DSP project files to build a 32-bit application.

The non-Windows C examples in the C folder of the installation directory provide a more complete set of

examples. You can compile these programs as 32-bit console applications for Windows by using the

MAKEMC32.BAT file.

Borland C /C++ for Windows

For 32-bit Borland (or Inprise) C/C++ compilers, include the Universal Library header file CBW.H in your

program and link with the import library file CBW32BC.LIB.

Borland C/C++ example programs

The non-Windows C examples provide an extensive set of examples. These can be compiled as 32-bit console

applications using the MAKEBC32.BAT file.
