Parameters
General
| Property | Type | Required | Default | Markup | Description |
|---|---|---|---|---|---|
| Application | Text | Yes | (Empty) | APPLICATION="Excel" | The name of the application the DDE conversation is initialized with. Each DDE conversation is uniquely defined by the application name and topic. At the beginning of a DDE conversation, the client and server determine the application name and topic. The application name is usually the name of the server application. For example, when Microsoft Excel acts as the server in a conversation, the application name is Excel. |
| Command | Text | Yes | (Empty) | COMMAND="MyCommand" | The
command string to execute by the DDE Server. NOTE: The server application defines the command strings supported for
a DDE conversation. For more information on the DDE commands supported
by a particular software program, see the program's user manual
or contact the software manufacturer. |
| Topic | Text | Yes | (Empty) | TOPIC="primary_file" | The
server-defined topic name of the DDE conversation. The DDE topic
is a general classification of data within which multiple data
items can be discussed (exchanged) during the conversation.
For applications that operate on file-based documents, the topic
is usually a file name. For other applications, the topic is an
application-specific name. NOTE:
The server application defines the topic names available for a
DDE conversation. See the documentation for the DDE server application
for specific information about the names of available topics. |
| Timeout (milliseconds) | Number | No | 60000 | TIMEOUT="99000" | Scalar specified timeout value (measured in milliseconds) for this operation. If this value is exceeded, a timeout error is returned. The default value is 60000 milliseconds (6 seconds). |
