InView Control
InView Control API

Introduction

The purpose of this chapter is to describe the API for the InView 
control. The chapter is divided into two sections. The first section is a 
quick overview on how to use the control. It highlights the basic steps 
needed to get the control up and running. The second section is a 
detailed reference of the properties and methods available in the 
control. Each property and method is listed in a table with a brief 
description and a link to a more complete description.

Quick Overview

The InView Control is designed primarily for use with the InView 
Messaging Software. The InView Messaging Software is used to create 
and download messages to the display, and the InView control is used 
to trigger the messages and update variables within those messages.   
Assuming that the InView Messaging Software has already been used 
to load the display with messages, there are five basic steps to using 
the control to trigger a message:

1.

Add the control to your project. It appears as InView Control 
under Project|Components… in Visual Basic.

2.

Call the 

Initialize

 method to open a connection to the display.

3.

Set the 

Heartbeat

 property to 2 to disable the display’s heartbeat 

requirement.

4.

Call the 

AddMessage

 method to trigger a message on the display.

5.

Call the 

UpdateVariable

 method to change the value of a 

variable.

Below is a snapshot of a Visual Basic form and its associated code that 
illustrates these five steps. This code assumes that the display contains 
a message in slot number 1, and that the message contains variable 0 
within its body. It also uses the controls default communications 
settings of serial on COM1 to connect with the display.
