[Interest] Generating unique string

Thanks guys for your answers. UUID is good enough for my task.

If you don't like the uuid format, you could hash the uuid or convert its binary representation to base64

        I'd suggest the uuid over the hash, unless you use a randomized hash content. Time is not good enough. Uuids are supposed to be unique, I'd use those.

        Have a look also to this : http://qt-project.org/doc/qt-4.8/quuid.html

          Igor,
          You might want to look at QCryptographicHash and then truncate or concatenate to N chars. Either that or QDateTime using the epoch. Your solution depends on how you are defining unique. Either way should be fairly simple.

            Hi.

            Does Qt have something for generating unique string of N chars?

            Or maybe does somebody know simple way to do it?

            Thanks.
