ddepoke

Send data to application

Syntax

• rc = ddepoke(channel,'item',data)
  rc = ddepoke(channel,'item',data,format)
  rc = ddepoke(channel,'item',data,format,timeout)
  

Description

ddepoke sends data to an application via an established DDE conversation. ddepoke formats the data matrix as follows before sending it to the server application:

• String matrices are converted, element by element, to characters and the resulting character buffer is sent.
• Numeric matrices are sent as tab-delimited columns and carriage-return, line-feed delimited rows of numbers. Only the real part of nonsparse matrices are sent.

If you omit optional arguments that are not at the end of the argument list, you must substitute the empty matrix for the missing argument(s).

If successful, ddepoke returns 1 in variable, rc. Otherwise it returns 0.

Arguments

channel	Conversation channel from ddeinit.
item	String specifying the DDE item for the data sent. Item is the server data entity that is to contain the data sent in the data argument.
data	Matrix containing the data to send.
format (optional)	Scalar specifying the format of the data requested. The value indicates the Windows clipboard format to use for the data transfer. The only format currently supported is cf_text, which corresponds to a value of 1.
timeout (optional)	Scalar specifying the time-out limit for this operation. timeout is specified in milliseconds. (1000 milliseconds = 1 second). The default value of timeout is three seconds.

Examples

Assume that a conversation channel with Excel has previously been established with ddeinit. To send a 5-by-5 identity matrix to Excel, placing the data in Row 1, Column 1 through Row 5, Column 5:

• rc = ddepoke(channel, 'r1c1:r5c5', eye(5));
