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. |
