A Variant value. Holds byte array data that was sent from remote side.
Remarks
IncomingData event is fired when remote side has sent us some data using
SendData method. You should retrieve it as byte array
[for C++ users this is SAFEARRAY(VT_ARRAY | VT_UI1)].
If you prefer to send/receive text messages, use
SendText so that
IncomingText event is
fired instead.
