Request data from DDE server application
Syntax
data = ddereq(channel, item, format, timeout)
Arguments
data
A matrix that contains the requested data, empty if the function call failed.
channel
The channel assigned to the conversation, returned by ddeinit.
item
A string that specifies the server application's DDE item name for the data requested.
format
(optional) A two-element array that specifies the format of the data requested.
The first element indicates a Windows clipboard format to use for the request. MATLAB supports only Text format, which corresponds to a value of 1.
The second element of the format array specifies the type of the resultant matrix. The valid types are NUMERIC (the default, corresponding to a value of 0) and STRING (corresponding to a value of 1).
The default format array is [1 0].
timeout
(optional) A scalar that specifies the time-out limit for this operation. timeout is specified in milliseconds (1000 milliseconds = 1 second). The default timeout is three seconds.
Description
ddereq requests data from a server application via an established DDE conversation. ddereq returns a matrix containing the requested data or an empty matrix if the function is unsuccessful.
Example
% Request a matrix of cells from Excel.
mymtx = ddereq(channel, 'r1c1:r10c10');
