Sending messages is an asynchronous operation that requires opening the destination queue and sending the message.
The body of an MSMQ message can be any intrinsic Variant, including string, date, currency, any number type, an array of bytes, as well as any persistent ActiveX object that supports IDispatch and IPersist (IPersistStream or IPersistStorage).
