DDE

DDE is a Dynamic Data Exchange (DDE) mechanism ). To Use DDE for communication, two Windows applications Program are required. One is used as the server to process information, and the other is used as the client to obtain information from the server. The client application sends a message request message to the currently activated server application. The server application responds to the message to exchange data between the two programs. In labview6.0 and later versions, DDE can still be used, but Ni prefers ActiveX, therefore, the dde vi is not automatically displayed on the function template. If you use this function, you can find it in LabVIEW x. x \ VI. Lib \ platform \ DDE. LLB. Working Principle of DDE (Dynamic Data Exchange): Party A applies for a global memory, and then sends the memory pointer postmessage to Party B, Party B accesses the global memory based on the received pointer. there are several API functions that do this. In msdn, you can check all the DDE headers. because it is an obsolete technology, it is not encapsulated by MFC. it is hard to ensure that it will also appear in future windows APIs. DDE = Dynamic Data Exchange is a 16-bit Windows technology that enables data exchange and control between different applications. Currently, it is rarely used, in Windows Shell, DDE is also used to open some file types. OLE = Object Linking and Embedding, developed from the 16-bit windows era and based on COM (in fact, Ole is the first practical application of COM, the com standard has not yet been finalized; the maturity of COM depends on the technical maturity of OLE), and the latest com standard is version 0.9.
