Generating unique IDs

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,

Try GUIDGEN.EXE

Incedentally, are you using DCOM? If not, what then?

What are you using to send messages from one application to the other?

If you need a GUID for each message sent, there's an API call that will generate one. I *think* it's "CreateGUID" but not sure.

I've used it before but don't have the code infront of me.

Thank you. I knew there was an API (because I've seen if before) but could remember the name.
