Rockwell Automation 8520-9API 9/Series OCI API Developer's Guide - Manual (Page 24)

3–3 OCI Basic Display Set (BDS)
Publication 8520-6.6 - August 1999
When the setup utility is complete the Visual Basic Pro project file
ABOCI.VBP is installed in the source code directory. Before you
can open this project in Visual Basic, you must first install the
custom OCX called RSData. This custom OCX is an improved DDE
tool used extensively in the Basic Display Set source code.
RSData
t is a Microsoft OLE custom control (OCX) created by
Rockwell Software. The RSData control is designed to be used with
any Dynamic Data Exchange Server and provides enhanced
performance when used with applications that conform to
AdvanceDDE
t protocol. This custom OCX is used extensively in
the Basic Display Set source code.
The RSData OCX uses a high speed DDE communications module
called RSJunctionBox
t. RSJunctionBox allows RSData to
communicate with the OCI DDE data server with considerably
higher performance than standard DDE communications provide.
To install the RSData Custom OCX and the RSJunctionBox DDE
communications module follow the instructions that accompanied
these Rockwell Software products.
The Basic Display Set pulls data from a variety of subdirectories
created during the setup of both the Basic Display Set executable and
source code. This directory structure must be maintained to properly
compile the source code. These subdirectories of the source code are
as follows:
This Directory: Contains this Data
ABOCI or
ab9pc
This is the main source code directory. All other
directories in this table are subdirectories of ABOCI
or ab9PC. This directory contains the main Visual
Basic project manager ABOCI.VBP.
ABOCI\BAS or
ab9pc\BAS
Basic routines commonly used by different forms in
the Basic Display Set.
ABOCI\DAT or
ab9pc\DAT
Contains the text files for softkey names, error
messages, and screen text. Note files exist in this
directory for each of the supported 9/Series
languages.
ABOCI\FIL or
ab9pc\FIL
Contains data for the Allen Bradley part program
editor
ABOCI\FRM or
ab9pc\FRM
Forms used to generate the Basic Display Set
screens.
ABOCI\PIC or
ab9pc\PIC
Graphics files used by the Visual Basic application.
