DDE Error Codes

The DDE VIs can return the following error codes. Refer to DDE Advise Start or to the Using DDE in LabVIEW Application Note for more information about DDE.

Code Name Description
00000 No error.
14001 DDE_INVALID_REFNUM Invalid refnum.
14002 DDE_INVALID_STRING Invalid string.
14003 DDEML_ADVACKTIMEOUT A request for a synchronous advise transaction has timed out.
14004 DDEML_BUSY The response to the transaction caused the DDE_FBUSY to be set.
14005 DDEML_DATAACKTIMEOUT A request for a synchronous data transaction has timed out.
14006 DDEML_DLL_NOT_INITIALIZED The DDEML function was called without first calling the DdeInitialize function, or an invalid instance identifier was passed to a DDEML function.
14007 DDEML_DLL_USAGE An application initialized as APPCLASS_MONITOR has attempted to perform a DDE transaction, or an application initialized as APPCMD_CLIENTONLY has attempted to perform server transactions.
14008 DDEML_EXECACKTIMEOUT A request for a synchronous execute transaction has timed out.
14009 DDEML_INVALIDPARAMETER A parameter failed to be validated by the DDEML: e.g., the data handle is initialized with a different name-item or different clipboard data format than that required; the application used a client.
14010 DDEML_LOW_MEMORY A DDEML application has created a prolonged race condition (where the server application outruns the client), causing large amounts of memory to be consumed.
14011 DDEML_MEMORY_ERROR A memory allocation failed.
14012 DDEML_NOTPROCESSED A transaction failed.
14013 DDEML_NO_CONV_ESTABLISHED A client's attempt to establish a conversation has failed.
14014 DDEML_POKEACKTIMEOUT A request for a synchronous poke transaction has timed out.
14015 DDEML_POSTMSG_FAILED An internal call to the PostMessage function has failed.
14016 DDEML_REENTRANCY An application instance with a synchronous transaction already in progress attempted to initiate another synchronous transaction, or the DdeEnableCallback function was called from within a DDEML call.
14017 DDEML_SERVER_DIED A server-side transaction was attempted on a conversation that was terminated by the client, or the server terminated before completing a transaction.
14018 DDEML_SYS_ERROR An internal error has occurred in the DDEML.
14019 DDEML_UNADVACKTIMEOUT A request to end an advise transaction has timed out.
14020 DDEML_UNFOUND_QUEUE_ID An invalid transaction identifier was passed to a DDEML function. Once the application has returned from an XTYP_XACT_COMPLETE callback, the transaction identifier for that callback is no longer valid.
14021 kInvalidCommand Invalid command code.
14022 kOccurenceTimeout Occurrence timeout; the transaction timed out before it completed.
