This section provides guidelines for implementing dynamic data exchange for applications that cannot use the Dynamic Data Exchange Management Library (DDEML). For more information about the DDEML, see Dynamic Data Exchange Management Library.
Specifies the quality of service (QOS) a raw Dynamic Data Exchange (DDE) application desires for future DDE conversations it initiates. The specified QOS applies to any conversations started while those settings are in place. A DDE conversation's quality of service lasts for the duration of the conversation; calls to the DdeSetQualityOfService function during a conversation do not affect that conversation's QOS.
Frees the memory specified by the lParam parameter of a posted DDE message. An application receiving a posted DDE message should call this function after it has used the UnpackDDElParam function to unpack the lParam value.
Initiates a conversation with a server application responding to the specified application and topic names. Upon receiving this message, all server applications with names that match the specified application and that support the specified topic are expected to acknowledge it.
A DDE client application posts a WM_DDE_EXECUTE message to a DDE server application to send a string to the server to be processed as a series of commands. The server application is expected to post a WM_DDE_ACK message in response.
A DDE client application posts a WM_DDE_POKE message to a DDE server application. A client uses this message to request the server to accept an unsolicited data item. The server is expected to reply with a WM_DDE_ACK message indicating whether it accepted the data item.
A DDE client application posts a WM_DDE_UNADVISE message to inform a DDE server application that the specified item or a particular clipboard format for the item should no longer be updated. This terminates the warm or hot data link for the specified item.
Contains flags that specify how a DDE server application should send data to a client application during an advise loop. A client passes a handle to a DDEADVISE structure to a server as part of a WM_DDE_ADVISE message.
