Embed OLE Custom Controls

Note: This information pertains to Microsoft Win32 only.

You can embed an OLE custom control (an OCX) on a window or dialog box that is controlled by a CA Gen application.

Examples of OCXs are spin buttons, gas gauges, and other graphic gadgets. These controls let you give the user an indication of the time it will take to accomplish a specific task.

The following list detail considerations for OCX controls on windows or dialog boxes:

• The OLE object does its own resizing.
• Each OCX provides its own sets of events.
• In addition to the CA Gen properties, each OCX contains properties.
• The number of properties is not limited.
• Information about OCX properties should be delivered with the OCX itself.
