Using DDE Functions

Although the Copy/Paste Link method of exchanging data is quite simple, advanced DDE applications can be constructed using DADiSP's built in DDE functions. The DDE functions are most often used when DADiSP acts as a DDE client.

The following table lists available DDE functions and actions:

Function	DDE Action
DDEINITIATE	Start a DDE conversation, returns a channel number.
DDEREQUEST	Get a data item as text from another application.
DDEPOKE	Send a data item as text to an application.
DDEGETDATA	Get a series from another application.
DDEEXECUTE	Execute a command in another application.
DDEADVISE	Automatically retrieve a series from an application whenever the data changes.
DDEUNADVISE	Cancel a ddeadvise operation.
DDELINK	Automatically retrieve a series from an application whenever the data changes. The channel number is managed internally.
DDEUNLINK	Cancel a ddelink operation
DDEGETLINK	Get the link name from the Clipboard
DDESTATUS	Get the status of the last DDE operation.
DDETERMINATE	End a DDE conversation.
