DDEConnect

DDEConnect opens a DDE connection.

Syntax

CALL ui.Interface.frontCall("WINDDE","DDEConnect",
 [ program, document, encoding ], [result] )

program is the name of the DDE application.
document is the document that is to be opened.
encoding is an optional parameter. It allows to force the encoding to use between ASCII and wide char/unicode. When not specified, WinDDE will try to retrieve the correct encoding by itself. Possible values are:
- UNICODE
- ASCII
result is an integer variable receiving the status.
result is TRUE if the function succeeded, FALSE otherwise.
If the function failed, use DDEError to get the description of the error.

If the function failed with DMLERR_NO_CONV_ESTABLISHED, then the DDE application was probably not running. Use the execute or shellexec front call to start the DDE application.
In Microsoft™ Office 2010, the use of DDE is disabled by default. You need to uncheck Ignore other applications that use Dynamic Data Exchange(DDE) in advanced options, otherwise DDEConnect will fail.
