DdeExecute
Sends a command or series of commands to a dynamic-data exchange (DDE) application.
Syntax
DdeExecute "appName", "topic", "command"[, async]
Argument Description
appName The name of the DDE application receiving the command. The appName value is
usually the name of the application's .EXE file without the file name extension.
The application must be running.
topic The name of a topic recognized by the application. Many DDE applications
recognize a topic named "System", which is always available. Each open
document may also be a separate topic.
command A command or series of commands recognized by the DDE application. Most
applications require that each command received through a DDE channel be
enclosed in square brackets. See Examples. Do not include spaces between
bracketed commands.
async If 0 or omitted, this call is synchronous and waits until the DDE application
acknowledges completion or a timeout occurs. If 1, this call is asynchronous and
returns immediately.
Example 1
This example opens a channel to Microsoft Excel and the System topic, and then sends a command to open
EXPENSES.XLS. The document name must be enclosed in two sets of quotation marks.
DdeExecute "Excel", "System", "[OPEN(""Expenses.xls"")]"
Example 2
This example tells Microsoft Word to decrease the font size of selected text.
DdeExecute "WinWord", "System", "[ShrinkFont]"
Notes
Use a DdeExecute instruction instead of SendKeys if you cannot be sure a key sequence always produces the
same result. A key sequence can have different results depending on whether it is received by the
application window or an open dialog box.
Set async to 1 if you are calling a DDE command that does not return immediately. Otherwise, if the DDE
command does not return quickly, DdeExecute fails with a timeout error and Dragon NaturallySpeaking
displays an error message.
DdePoke
Uses an open dynamic-data exchange (DDE) channel to send data to an application.
