C# Make Text Bold, without selection.

[TriggerHappy]

How could I make a C# text bold, note that i'm using a rich text box.

        string Bold(string input)
        {
            return @"{\rtf1\ansi\b" + input + "\b0.}";
        }

        private void richTextBox1_TextChanged(object sender, EventArgs e)
        {
            int i = 0;
            while (i < boldcount)
            {
                jass.Text = jass.Text.Replace(bold[i], Bold(bold[i]));
                jass.SelectionStart = jass.TextLength;
                i = i + 1;
            }
        }

Thats what I got, but this is what the text looks like when shown.

{\rtf1\ansi\bfunction0.}

But theres a weird symbol between the \b and the "f" in function.

Shouldn't it be \\ instead of \ ?

Well I didn't get an escape character error.

EDIT:

        string Bold(string input)
        {
            return @"{\\rtf1\\ansi\\b" + input + "\\b0.}";
        }

Turns it into this..

{\\rtf1\\ansi\\bfunction\b0.} (yes, it colors it?, looks like a link).

\bfunction\b0 is wrong. It'd work better as \b{function}\b0.
Why don't you use the Rich Text functions that come with C#? You wouldn't have to mess with a formatting language you don't master.

Because it requires you to select the text before changing the font, which is laggy and noticeable.

RTFM? Just disable the redraw.

Actually, the @ before the string delimiter causes characters in the string to be interpreted literally, not as escape sequences.

oh thats what it means

Thanks.

EDIT: Still produces the same result...

        string Bold(string input)
        {
            return @"{\rtf1\ansi\b{" + input + "}\b0.}";
        }

You still aren't able to figure it out all by yourself?

Either (if you read Samuraid's post):

@"}\b0.}"

or:

"}\\b0.}"

Still doesn't work.

        string Bold(string input)
        {
            return @"\rtf1\ansi\b{" + input + @"}\b0.}";
        }

"It does not work" is not a valid problem description.

You did notice the the missing { before the \rtf1 ? I'll give you exactly one more try to either get things right or post enough information to solve this "problem".

Otherwise I'm going to close this thread.

Even after you get the straightforward things right, it'll still not work. Judging by your code snippet, you aren't ensuring that the things you highlight are always formatted correctly. So, why not simply use the provided RTF manipulation classes/methods?

Well I thought my problem was self explanatory.. it's the same as before.

Turns it into this..

{\\rtf1\\ansi\\bfunction\b0.} (yes, it colors it?, looks like a link).

Even with it there, it does not work..

I stated before that the only way I could find to highlight text is by selecting it, which is laggy and noticeable.

If you can't it done all by yourself, just use somebody elses code.
