Using OLE Support

In this chapter, you learn how to use the OLE Support feature in your VA Smalltalk application. The feature enables you to use OLE clients and custom control services in VA Smalltalk applications.

The OLE Support feature is only available in VA Smalltalk for Windows. It is not available for AIX, Sun Solaris, or Linux.

OLE (or Object Linking and Embedding) is a unified environment of object-based services that can be customized and used to extend the environment.

The VA Smalltalk parts related to OLE are:

OLE category

OLE Client

Accesses and uses an OLE server application, such as Paintbrush or WordPad

OLE Control

Enables the use of a custom Windows control that is built with OLE technology, commonly known as an OCX

OLE File

Enables transparent persistence of linked or embedded OLE objects into files

Note

How to copy from Windows Explorer into an OLE Client part

Use copy and paste to share OLE objects between the Windows Explorer and an OLE Client part. Dropping an OLE object that was dragged from the Windows Explorer onto an OLE Client part does not work.
