A feature that allows two Windows programs to share data. PassageWay(tm) Telephony Services DDE links the system's telephone features with other Windows applications so users can have programs such as databases and PIMs that mirror AT&TCall's call processing features. (See also OLE.)

A limited method of sharing data between two applications or files. When data is used in both files, with DDE it can be automatically updated in the other. Both applications have to be in use, and DDE does not work over a network. Object Linking and Embedding (OLE) is a more sophisticated development.

A form of interprocess communications that uses shared memory to exchange data between applications. DDE can be used for one-time data transfers and for ongoing exchanges by applications that send updates to one another as new data becomes available. See also client/server, OLE Automation.

A form of interprocess communications (IPC) in which two or more programs that support dynamic data exchange can exchange information and commands.

A Microsoft Windows 3 hotlink protocol that allows applications programs to communicate using a client-server model. Whenever the server (or "publisher") modifies part of a document, which is being shared via DDE, one or more clients ("subscribers") are informed and include the modification in the copy of the data on which they are working.

DDE is a method of passing information between Windows applications. You can pass addressing information from other Windows applications to the Zetafax client, removing the need to address the fax manually using the addressing dialog box.

An inter-process communication method featured in Microsoft Windows and OS/2. DDE allows two or more programs that are running simultaneously to exchange data and commands. In Windows 3.1, DDE was largely supplanted by OLE, which is an extension of DDE. In Windows 95 and Windows NT, OLE and Active X are more commonly used.

(DDE): A process that simplifies exchange of data between computer programs. Using DDE, programs can actively exchange data, and update information continually in real time as it changes. For DDE to occur, the programs must conform to specifications for Microsoft Windows.

Dynamic Data Exchange (DDE) is a form of InterProcess Communication (IPC) in the Microsoft Windows operating environemnt. When two or more applications that support DDE are running simultaneously, they can exchange information, data and commands. DDE has been enhanced with Object Linking and Embedding (OLE) technology.

A proprietary method of linking the data in one application to a graphical or other display in another application. When the data is changed in the first program, the display in the second is updated automatically, allowing a single master set of data to be used for all purposes.

A protocol that allows applications to exchange data on a real-time basis by means of messages passed between windows.

An industry standard accepted by most horizontal application software for exchanging data among different software programs.

A Microsoft Windows standard mechanism for communication between programs. It allows your application to send and share data with other applications such as spreadsheets.

A standard Microsoft Windows protocol that defines a way for Windows applications to share information with one another.

A system that allows two applications programs to be linked together so that a change made in one application is immediately reflected in the other.

Dynamic Data Exchange (DDE) is a technology for communication between multiple applications under Microsoft Windows and OS/2.
