I need to generate a random unique ID to be used as an unique identifier for a message that needs to be sent to another application.
The idea, is that this other application does not answer, the message will be re-sent. And if this application wants to answer... it would be great to know which is "he" responding to.
In other words, I need unique identifiers (for each message being sent) so that the program can identify which answer belong to each question. TIA,
