DDE Link Between FoxPro and WordPerfect for Windows

• Microsoft FoxPro for Windows, versions 2.5 and 2.5a

SUMMARY

The procedure below tests for the establishment of a dynamic data exchange (DDE) link between Microsoft FoxPro for Windows and WordPerfect version 5.2 for Windows. In this scenario, FoxPro functions as a DDE server and WordPerfect functions as a DDE client.

MORE INFORMATION

1. Open a FoxPro for Windows session and issue the following command to establish FoxPro as a DDE server:

         DO c:\foxprow\sample\dde\ddedata.app
   

2. Switch to Program Manager and open a WordPerfect for Windows session.

3. Create a document with the following commands and save it as INIT.WPM.

         Application (WP;WPWP;Default;"WPWPUS.WCD")
         // The following command would change to
         // reflect the FoxPro table name used in the session
         DDEInitiate(handle;"ddedata";
            "c:\foxprow\sample\organize\dbfs\;TABLE personal" )
         IF (handle = 0)
         // Connection cannot be established
            MESSAGE:="Cannot init conversation with FoxPro"
            NUMSTR(Show;;handle)
            PROMPT("Error";"handle:"+Show+ " - " + Message;1;;)
               PAUSEKEY(Key:Enter!)
            ENDPROMPT
         ELSE
         // A DDE conversation has begun
            MESSAGE:="Connection established!!!"
            NUMSTR(Show;;handle)
            PROMPT("Success";"handle:"+Show+ " - " + Message;4;;)
               PAUSEKEY(Key:Enter!)
            ENDPROMPT
          ENDIF
   
   

4. Close the INIT.WPM file.

5. From the Macro menu, choose Play. Double-click the INIT.WPM file.

6. If a DDE session can be established, a dialog box will appear with the message "Connection established!!!"

7. If a DDE session cannot be established, a dialog box will appear with the message "Cannot init conversation with FoxPro."
