      void onError(int transactionType, Ddeml.HCONV hconv, int errorCode)
      A Dynamic Data Exchange (DDE) callback function, DdeCallback, receives the XTYP_ERROR transaction when a critical error occurs.

      Remarks

      An application cannot block this transaction type; the CBR_BLOCK return code is ignored. The Dynamic Data Exchange Management Library (DDEML) attempts to free memory by removing noncritical resources. An application that has blocked conversations should unblock them.

      Parameters:
      transactionType - uType - The transaction type.
      hconv - A handle to the conversation associated with the error. This parameter is NULL if the error is not associated with a conversation.
      errorCode - dwData1 - The error code in the low-order word. Currently, only the following error code is supported.

      Only Ddeml.DMLERR_LOW_MEMRORY is known: Memory is low; advise, poke, or execute data may be lost, or the system may fail.
