Re: Escaping strings?

I think you also have to escape underscore(_).

You need to escape \ and ' but using setString() is the most portable
way of doing it. Escape them both with \. Something like this...

StringBuffer sbuf = new StringBuffer();
for(i = 0; i < str.length(); i++)
{
    char c = str.charAt(i);
    if(c == '\\' || c == '\'')
        sbuf.append((char)'\\');
    sbuf.append(c);
}

Cheers,

Tom.
