Hi to all.

I know that ^ is the bitwise XOR operator, but what does it mean in the following:

String^ strSource = "changed"; //what is this ^ doing here?

Thanks

PS.
It's taken from:

That's a Microsoft specific Common Language Runtime specifier meaning the declared object is to be automatically garbage collected. This is not part of standard C++. You should find a microsoft specific newsgroup to find out more.

It's a totally different language, confusingly called C++/CLI, with its
very own standard

I know this isn't really the place, but I just spent the last 30 minutes looking for a visual c++ newsgroup, and I didn't find a thing! Does anyone know the precise address of the microsoft visual c++ newsgroup? (ie comp.lang.c++)

Thanks

Microsoft has replaced its newsgroups (microsoft.public.*) with web
based forums (Check Daniel's anwswer)

The official Microsoft newsgroups for VC++ used to be (from time to time
they have some minor activity):

microsoft.public.vc.* (language, stl, mfc, atl, debugger, etc)
microsoft.public.dotnet.languages.vc

Microsoft has decided that we don't want to use newsgroups anymore - old
technology! So the have set up some modern online forums instead.

Yea, their forums are a complete terd too. Good luck finding one where
any specific question is on topic and will receive a response by anyone
other than a moderator whom will mark his own post as the answer even
though your question never got addressed.
