unique-id

In any portlet application, if the same page containing a portlet is opened in two browser tabs, how is the event in the first page distinguished from the second page? I want to assign a unique Id for each event, store it and append it to the URL so that the link can be shared. Can someone provide their thoughts on this ? Also, if the page URL is opened on other computer the data shown on the page is the same as the data seen on the first computer. This is being set globally. How can I eliminate this?

I am developing a windows application in .NET Framework using C#.I want to know is there any Unique Id of each computer manufactured, let it be manufactured by any manufactrure but it must be unique. Thanks, Bibhu Check this : How to get the Computer's Unique ID Hard Drive ID (Volume Serial) Finding a unique volume serial works very similarly and luckily a bit simplier: ManagementObject dsk = new ManagementObject(@"win32_logicaldisk.deviceid=""" + drive + @":"""); dsk.Get(); string volumeSerial = dsk["VolumeSerialNumber"].ToString(); You could get the mac address if its a windows app. This

I have a bunch of C++ classes. I want each class to have something like: static int unique_id; All instances of a same class should have the same unique_id; different classes should have different unique_id's. The simplest way to do this appears to be threading a singleton through the classes. However, I don't know what's called when for static class members / things that happen before main. (1) if you have a solution that does not involve using singleton, that's fine too (2) if you have a solution that gives me a : int unique_id(); that is fine too. Thanks! Have a class that increments it's

I've an Express app. I'd like to trace all the loggings that were made by a single request. Apache has a module called mod_unique_id which injects in the request headers a special one containing a unique hash. I'd like to use such hash when logging (anything). For example if an user is assigned by apache the unique_id valued "abcdefg" and somewhere in my code (controller, model, or anything) i generate a debug log i'd like to have "abcdefg" attached to every log entry. The only idea that pops in my mind is to create a logger instance using app.use() and pass that logger instance to ALL the
