DDE and WinWedge:
Understanding DDE
Sending Keystrokes Vs. Dynamic Data Exchange (DDE)
The Wedge can transfer data to other programs by converting serial
data to keystrokes or by passing data via DDE. Which way is better
and what are the advantages or disadvantages of either method?
WinWedge DDE Examples
Typical DDE Examples for Excel, Access, Word, FoxPro, VB, Lotus 123,
Quattro Pro, Visual Basic, etc. NOTE, DDE is just one data transfer
option in WinWedge, it may be easier for you to use the "Send
Keystrokes" Method (see "Quick Start Guide")
Sample Excel DDE Workbook
This Workbook contains examples to request multiple fields of data
from WinWedge, request data from multiple Wedges simultaneously,
request a single field of data and place it in the active cell, and
several examples of how to send data out the serial port from Excel.
