Using Your Own ActiveX Control

To use your own ActiveX control in a Simulink model, you must associate it with the generic ActiveX Control block. This section discusses how to use the ActiveX Control block, in these subsections:

• Adding the ActiveX Control Block to a Model
• Summary of Dialog Box Fields and Check Boxes
• Notes on Third-Party ActiveX Control Blocks

Adding the ActiveX Control Block to a Model

To configure the ActiveX Control block to display a specific ActiveX control, you need to know some of the programming features of the ActiveX control:

• The name under which the ActiveX control is registered on your system
• The events that cause the ActiveX control to perform an action
• The ActiveX control properties that are affected by events, by signals passed to the block, or by initialization commands

To use an ActiveX Control block in a Simulink model:

1. Drag the ActiveX Control block from the top level of the Dials & Gauges Blockset to your model. Place the block where you want the control to appear.

   

2. Double-click on the block to display its Block Parameters dialog box. Specify the appropriate values, described in subsequent sections.

   

Note    Double-clicking on the border of a preconfigured block (supplied with the blockset) displays its ActiveX Control Properties dialog box, which lists properties in multiple tabbed panels. Double-clicking on a block that you created by customizing the generic ActiveX Control block displays its Block Parameters dialog box.
