What is an OLE-embedded diagram?

Definition

An OLE (Object Linking and Embedding) Embedded Diagram contains an object from an OLE-compliant program which is embedded in or linked to the diagram window. IGSS Definition becomes the OLE container program and the target program becomes the OLE server.

Use

By using OLE-embedded diagrams, you can embed or link any kind of OLE object registered on your PC. The only limit to its use is your own imagination.

A few examples could be:

Create and maintain internal procedures in a Word file that operators can access by clicking a field or button referencing the OLE-embedded diagram.
Link to one of your own OLE-compliant programs that you use during supervision

The menus and functions available will reflect the functionality of the OLE server program, but you can, of course, always open another area or diagram from their respective menus.

Create New or Create from File

When you create an OLE-embedded diagram, you can either create a new OLE object or embed or link to an existing file.

Diagram menu

As is the case for normal diagrams, you can add the name of an OLE-embedded diagram to the Diagram menu simply by checking the Name to Menu option when you define the diagram.

OLE-embedded diagram properties

When you create an OLE-embedded diagram, you specify a number of properties in the OLE Object Properties dialog box. The properties can be changed at any time. The most important ones are:

This property…	Allows you to …
Browse	select the appropriate OLE object type and either create a new OLE object or select an existing file in the Insert Object dialog box.
OLE Object Name	view the selected OLE object type. This information is automatically inserted by IGSS, for example, PSP.Image for an image created in the graphics program, Paint Shop Pro.
Window elements	specify which diagram window elements you want the operator to see, for example, title bar, minimize and maximize buttons, etc.
Name to Menu option	show the diagram name in the Diagram menu to facilitate easy access for the operator.

For an explanation of the remaining properties, open the Diagram Properties dialog box, click the $images\ico_help.gif$ in the upper right hand corner of the dialog box, then click the item you want information about.
