      public void initialize(int afCmd) throws DdemlUtil.DdemlException
      Beschreibung aus Schnittstelle kopiert: DdemlUtil.IDdeClient
      Registers an application with the Dynamic Data Exchange Management Library (DDEML). An application must call this function before calling any other Dynamic Data Exchange Management Library (DDEML) function.
      Angegeben von:
      initialize in Schnittstelle DdemlUtil.IDdeClient
      Parameter:
      afCmd - A set of APPCMD_, CBF_, and MF_ flags. The APPCMD_ flags provide special instructions to DdeInitialize. The CBF_ flags specify filters that prevent specific types of transactions from reaching the callback function. The MF_ flags specify the types of DDE activity that a DDE monitoring application monitors. Using these flags enhances the performance of a DDE application by eliminating unnecessary calls to the callback function.

      This parameter can be one or more of the following values.

      ValueMeaning
      APPCLASS_MONITOR
      0x00000001L

      Makes it possible for the application to monitor DDE activity in the system. This flag is for use by DDE monitoring applications. The application specifies the types of DDE activity to monitor by combining one or more monitor flags with the APPCLASS_MONITOR flag. For details, see the following Remarks section.

      APPCLASS_STANDARD
      0x00000000L

      Registers the application as a standard (nonmonitoring) DDEML application.

      APPCMD_CLIENTONLY
      0x00000010L

      Prevents the application from becoming a server in a DDE conversation. The application can only be a client. This flag reduces consumption of resources by the DDEML. It includes the functionality of the CBF_FAIL_ALLSVRXACTIONS flag.

      APPCMD_FILTERINITS
      0x00000020L

      Prevents the DDEML from sending XTYP_CONNECT and XTYP_WILDCONNECT transactions to the application until the application has created its string handles and registered its service names or has turned off filtering by a subsequent call to the DdeNameService or DdeInitialize function. This flag is always in effect when an application calls DdeInitialize for the first time, regardless of whether the application specifies the flag. On subsequent calls to DdeInitialize, not specifying this flag turns off the application's service-name filters, but specifying it turns on the application's service name filters.

      CBF_FAIL_ALLSVRXACTIONS
      0x0003f000

      Prevents the callback function from receiving server transactions. The system returns DDE_FNOTPROCESSED to each client that sends a transaction to this application. This flag is equivalent to combining all CBF_FAIL_ flags.

      CBF_FAIL_ADVISES
      0x00004000

      Prevents the callback function from receiving XTYP_ADVSTART and XTYP_ADVSTOP transactions. The system returns DDE_FNOTPROCESSED to each client that sends an XTYP_ADVSTART or XTYP_ADVSTOP transaction to the server.

      CBF_FAIL_CONNECTIONS
      0x00002000

      Prevents the callback function from receiving XTYP_CONNECT and XTYP_WILDCONNECT transactions.

      CBF_FAIL_EXECUTES
      0x00008000

      Prevents the callback function from receiving XTYP_EXECUTE transactions. The system returns DDE_FNOTPROCESSED to a client that sends an XTYP_EXECUTE transaction to the server.

      CBF_FAIL_POKES
      0x00010000

      Prevents the callback function from receiving XTYP_POKE transactions. The system returns DDE_FNOTPROCESSED to a client that sends an XTYP_POKE transaction to the server.

      CBF_FAIL_REQUESTS
      0x00020000

      Prevents the callback function from receiving XTYP_REQUEST transactions. The system returns DDE_FNOTPROCESSED to a client that sends an XTYP_REQUEST transaction to the server.

      CBF_FAIL_SELFCONNECTIONS
      0x00001000

      Prevents the callback function from receiving XTYP_CONNECT transactions from the application's own instance. This flag prevents an application from establishing a DDE conversation with its own instance. An application should use this flag if it needs to communicate with other instances of itself but not with itself.

      CBF_SKIP_ALLNOTIFICATIONS
      0x003c0000

      Prevents the callback function from receiving any notifications. This flag is equivalent to combining all CBF_SKIP_ flags.

      CBF_SKIP_CONNECT_CONFIRMS
      0x00040000

      Prevents the callback function from receiving XTYP_CONNECT_CONFIRM notifications.

      CBF_SKIP_DISCONNECTS
      0x00200000

      Prevents the callback function from receiving XTYP_DISCONNECT notifications.

      CBF_SKIP_REGISTRATIONS
      0x00080000

      Prevents the callback function from receiving XTYP_REGISTER notifications.

      CBF_SKIP_UNREGISTRATIONS
      0x00100000

      Prevents the callback function from receiving XTYP_UNREGISTER notifications.

      MF_CALLBACKS
      0x08000000

      Notifies the callback function whenever a transaction is sent to any DDE callback function in the system.

      MF_CONV
      0x40000000

      Notifies the callback function whenever a conversation is established or terminated.

      MF_ERRORS
      0x10000000

      Notifies the callback function whenever a DDE error occurs.

      MF_HSZ_INFO
      0x01000000

      Notifies the callback function whenever a DDE application creates, frees, or increments the usage count of a string handle or whenever a string handle is freed as a result of a call to the DdeUninitialize function.

      MF_LINKS
      0x20000000

      Notifies the callback function whenever an advise loop is started or ended.

      MF_POSTMSGS
      0x04000000

      Notifies the callback function whenever the system or an application posts a DDE message.

      MF_SENDMSGS
      0x02000000

      Notifies the callback function whenever the system or an application sends a DDE message.

      public Ddeml.HSZ createStringHandle(String value) throws DdemlUtil.DdemlException
      Beschreibung aus Schnittstelle kopiert: DdemlUtil.IDdeClient
      Creates a handle that identifies the specified string. A Dynamic Data Exchange (DDE) client or server application can pass the string handle as a parameter to other Dynamic Data Exchange Management Library (DDEML) functions.
      Angegeben von:
      createStringHandle in Schnittstelle DdemlUtil.IDdeClient
      Parameter:
      value - The string for which a handle is to be created. This string can be up to 255 characters. The reason for this limit is that DDEML string management functions are implemented using atoms.
      Gibt zurück:
      If the function succeeds, the return value is a string handle. A parameter NULL will cause NULL to be returned.

      If the function fails, a DdemlException is raised with the corresponding errorCode:

      public DdemlUtil.IDdeConnectionList connectList(Ddeml.HSZ service, Ddeml.HSZ topic, DdemlUtil.IDdeConnectionList existingList, Ddeml.CONVCONTEXT ctx)
      Beschreibung aus Schnittstelle kopiert: DdemlUtil.IDdeClient
      Establishes a conversation with all server applications that support the specified service name and topic name pair. An application can also use this function to obtain a list of conversation handles by passing the function an existing conversation handle. The Dynamic Data Exchange Management Library removes the handles of any terminated conversations from the conversation list. The resulting conversation list contains the handles of all currently established conversations that support the specified service name and topic name.
      Angegeben von:
      connectList in Schnittstelle DdemlUtil.IDdeClient
      Parameter:
      service - A handle to the string that specifies the service name of the server application with which a conversation is to be established. If this parameter is 0L, the system attempts to establish conversations with all available servers that support the specified topic name.
      topic - A handle to the string that specifies the name of the topic on which a conversation is to be established. This handle must have been created by a previous call to the DdeCreateStringHandle function. If this parameter is 0L, the system will attempt to establish conversations on all topics supported by the selected server (or servers).
      existingList - An existinct conversation list to be enumerated. This parameter should be NULL if a new conversation list is to be established.
      ctx - A pointer to the CONVCONTEXT structure that contains conversation-context information. If this parameter is NULL, the server receives the default CONVCONTEXT structure during the XTYP_CONNECT or XTYP_WILDCONNECT transaction.
