CoCreateGuid

[Darren Coolidge]

CoCreateGuid creates nice guids but, when the same program still has the dll
loaded, VB, the guids it creates appear to be linear, no matter how much
time has gone by. How would you suggest we create non-linear guids?

All CoCreateGuid guarantees is that they be unique - not that they be non-linear.

Seems to me if you must be non-linear, it means you'll have to use a separate
DLL that you can
be sure it is loaded an unloaded. Sorry I don't have a better idea offhand.

Darren,

Just FYI, the implementation of CoCreateGuid has changed in Windows
2000. It now generates non-linear series of GUIDs. They also aren't
based on the MAC address of your NIC anymore.
