Unique EventID

Hi

Has anyone implemented a unique number generator for the EventLog EventID?
I need to populate the EventID since I have an application that reads the
EventLog.

Any help is highly appreciated.
 
Hi

I get the following error when I use
BitConverter.ToInt32(Guid.NewGuid().ToByteArray(), 0);

An unhandled exception of type 'System.ArgumentException' occurred in
system.dll

Additional information: Invalid eventID value '1296869646'. It must be
in the range between '0' and '65535'.

Are there any companies out there that actually write to the EventLog
using unique EventID's?

I think Alphamacaroon meant to say
BitConverter.ToInt16(Guid.NewGuid().ToByteArray(), 0)

But:

I don't know. Bear in mind that there's a limit to how unique a value
in 0..65535 can be. Not that the above technique of taking the first
two bytes of a new GUID might not work, depending on the GUID
generation mechanism.

Why didn't ToInt32 work? Is EventID a short? Looks like it might be.

Actually, given that the error was
Additional information: Invalid eventID value '1296869646'. It must be
in the range between '0' and '65535'.

it looks like it wants a UInt16, not just an Int16 as my correction
suggested.
 
I agree. If this is true, then yes I would also agree that the
uniqueness of a UInt16 is pretty spotty.
