I know that C++ strings are supposed to be the "right" way to
handle strings but I suspect that converting "char *" to string

Hi,
I would like some advice on whether I should be using plain "chars"
for strings. I have instead been using "unsigned char" in my code (for
embedded systems). In general the strings contain ASCII characters in
the 0-127 range, although I had thought that I might want to use the
128-255 range for special symbols or foreign character codes.
This all worked OK for a long time, but a recent update to the
compiler on my system has...

Actually, because you are using the C++/CLI compiler,
microsoft.public.dotnet.languages.vc is the most appropriate place to
discuss this.
To be useful from C# and other .NET languages, the member functions of your
ref class should accept parameters of type System::String^. The C++/CLI
compiler provides some pretty simple methods for getting the data as native
C++ characters if you need to, for example the...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
