String Builder, appending carriage return

Hi,

I am trying to append a carriage return to my string using the string
builder class, but when I do this the string ends up containing "13".
I tried this multiple ways like so

sb->Append('\r');

and also

sb->Append(System::Windows::Forms::Keys::Enter);

and lastly i tried

sb->Append((char)13);

I also tried that last one without the char type casting and my string
still contains 13 instead of a code for carriage return. Any ideas??

I just realized this function is expecting a string, so a character
constant will not work. if you do

sb->Append("\r");

it will append a carriage return code.

or try:
sb.Append(Environment.NewLine);

No, that's carriage return and line feed. Carriage return ("\r") is 13,
and line feed ("\n") is 10. The two of them are used together for the
Windows line ending.

There *is* a method which accepts a char though. Perhaps the problem is
that it's expecting a .NET char (i.e. Unicode) rather than a C/C++
char. Did you try:

sb->Append (L'\r');

?

hey... I just started messing with .net so I'm not even sure what that
L does.. is that some kind of typecasting?? I keep seeing S used like
this in MSDN articles. Anyway, I just attempted the sb->Append(L'r');
and it still gives me 13 instead at the output.

thanks for all of the thoughts and comments, maybe some others will
find this useful as well.

As an aside, "\n" is the Unix equivalent. No CR.

I *think* S is used for a managed string, but to be honest I don't know
about managed chars. I don't know a lot about MC++ :(

Right - I think you'd have to find out what the equivalent of a .NET
char is in MC++ to work it out for sure.

If you're under .NET you can do sb->AppendLine("sometext");
Environment.NewLine will be appended after the text.

AppenLine internally uses this.Append(Environment.NewLine);

Do you mean "If you're under .NET 2.0"? AppendLine is new to 2.0.
