Exchanging data with other applications
In this section we will explore how DDE can be used in a VA Smalltalk application to exchange data with other commercial software. We'll first build a VA Smalltalk DDE server application that will send data to a Lotus 1-2-3 for OS/2 Release 2.0 spreadsheet. We will also build a VA Smalltalk DDE client application that will receive data from a Microsoft Excel for Windows 4.0 spreadsheet.
If you don't have these particular commercial software packages try to change the instructions to fit an application you do have. The key is that the application can act as a DDE client in the first example, and as a DDE server in the second example.
