      • onError

        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.
