I am using the code below, with this code I am getting an output in decimal. What I would like to do is output this in ASCII. Not sure how to implement that in visual c++

array<Byte>^ loc= gcnew array<Byte>(18);
            serialPort1->Read(loc,0,18);
            this->richTextBox3->AppendText(String::Format("{0}{1}{2}{3}{4}{5}{6}{7}",loc[9],loc[10],loc[11],loc[12],loc[14],loc[15],loc[16],loc[17])) ;

Solution 1

Use Convert.ToChar on your values, or use a format specifier. Here,[^] they are the same for all .NET languages.

C++

    array<Byte>^ loc= gcnew array<Byte>(18);
    int byteRead = serialPort1->Read(loc,0,18);

    StringBuilder builder;
    for (int i = 0; i != byteRead; ++)
    {
        // You must convert the "byte" into a "Char" to display the
        // character instead of its value (i.e. "A" instead of 65).
        Char theChar = loc[i];
        builder.Append(theChar);

        // The following line would also works (instead of the above 2).
        // builder.Append(static_cast<char>(loc[i]));
    }
    this->richTextBox3->AppendText(builder.ToString());
</char>

Solution 3

Forget about ASCII; .NET internally supports Unicode UTF-16. If you write .NET string to a file, you can use ASCII, of course, if all code points used are limited to 0..127. In this case, if you use UTF-8 without BOM, the output will be the same. But you're not asking about file/stream.

See:
http://en.wikipedia.org/wiki/ASCII[^],
http://en.wikipedia.org/wiki/Unicode[^],
http://unicode.org/[^],
http://unicode.org/faq/utf_bom.html[^].

Important material, my 5

Thank you, Espen.
I wonder how many people still have no idea about Unicode, including those using languages rather than English.
