12.1 DDE data exchange
DDE (Dynamic Data Exchange) is a mechanism for establishing and administe-
ring links between various Windows applications. The linked applications can
then exchange and update their data automatically.
In this process, there is a distinction to be made between the DDE client and the
DDE server. The DDE client signifies the part of the target application that recei-
ves the data from the DDE server. Conversely, the DDE server makes the data
from the source application available in line with the defined items.
MT9750 makes the DDE server function available. This means that data that is
supplied by a host application being used can be inserted and edited in another
Windows application. In this way, for example, the results of a database query
can be linked to Excel, edited further, and converted to graphic format.
The following steps are required to exchange data using DDE:
1. Definition of a DDE connection
2. Establishment of a DDE link in the target application
3. If automatic updating (hot link) was not configured, renewed data exchange
must be initiated by the user.
