Hi, I have a software that runs over 2 000 computers on my company, without any issues. This software, at some time, generate a GUID (or UUID) using UuidCreateSequential() (MSDN link). The call usually returns RPC_S_OK on every computer. But on one of them, it always returns RPC_S_UUID_LOCAL_ONLY. The documentation states that: T...
I am looking at UUID generation in Blackberrys. I need to be able to generate 128 bit UUIDs from last generation Blackberrys. I have just looked through the API and it looks like the javax.bluetooth.UUID class is the way to go. Can I assume that this API will be available for all Blackberrys? Is there another, more standard/better, way...

I will have a unique string that I could use for a seed for some algorithm that will generate a unique looking alphanumeric ID # for the order ...
How do you generate UUID of type long (64 bits - to be consumed by a java program) using Python? I read about the UUID module. So I played with it a bit: >>> import uuid >>> uuid.uuid1().int 315596929882403038588122750660996915734L Why is there an "L" at the end of the integer generated by uuid.uuid1().int? If it's an integer should...

I'm using coldfusion and I would like to generate a random salt field for my passwords. I was wondering if a CreateUUID() function is useful here. I found many examples which use a seperate function to create the salt string; but why do this when you could use rand() or CreateUUID() functions instead? I'm not sure. Is it an overkill or ...
I am having a problem with Hibernate. The primary key of ID in mysql table is UUID style String. e.g.08fe2a75-5d40-4645-896d-aab2a3ac96b8 But I can not use session.get() to fetch out the data for some reason.
