Agenda

• What Is DDE ?• BIS Support for DDE• Using DDE with:

- Excel - Word - Visual Basic

• DDE at Expanets• Questions and Answers

What is DDE?

Definition

• Dynamic Data Exchange

• An early Windows™ API that allows one DDE enhanced application to share data with or drive another DDE enhanced application

• Still supported but not being enhanced

• Replaced by OLE and other API’s

What is DDE?

Elements• Conversation - Windows assigns a handle - Can have more than one open

• Application - Name of main form (see manual)

• Topic - Document, worksheet or form

• Item - Bookmark, cell or field

What is DDE?

What can DDE do?• Read data

• Write data

• Link data items between applications

• Execute commands or macros

BIS Support for DDE

Requirements• BIS Hosts: - 2200, UNIX, NT, PC

• Workstations: - DW, PCE, MPC, GI

• Session: - foreground

Support• Outbound DDE only

BIS Support for DDE

@DDE: a function withmany command options

• (i) initiate a conversation

• (r) read data

• (p) poke data

• (e) execute command(s)

• (a) set an advise

• (u) clear an advise

@CLS close a conversation

Getting a Clean Start:

• Find out if any documents are open

• Close previously opened documents

• Open your own document
