version 6.0
Dynamic Data Exchange, or DDE, was introduced with Windows version 3.0. Its advantage is that it can be implemented on the vast majority of Windows applications.
DDE is a protocol that facilitates communication between two applications.
The three basic actions supported by DDE are:
• Request data
For example, you can request the contents of a Microsoft Excel cell from 4th Dimension, or you can request the value of a 4D field from Microsoft Word.
• Send data
For example, you can set the contents of an Excel cell from 4th Dimension, or conversely, set the contents of a 4D field from Excel.
• Implement commands
For example, you can request Excel to open a new document from 4th Dimension, or you can request 4D to execute a procedure from Microsoft Word.
