    Hi A famous Newbies example to declare a CString was CString welcome_string = "Welcome to Visual C++"; What if I want to declare a text that was as long as one paragraph? when I can't even do things like this CString welcome_string ="Welcome to Visual C++...not finish yet continue next line .....more text "; there was a "newline is constant" error. Please help X| Newbies

      you need a "\" as this: CString welcome_string ="Welcome to Visual C++...not finish yet continue next line\ .....more text "; to let the compiler know that this line is not finished. try it.

        this is easy: CString t= "hello \ world"; Pay attention to the backslash, type ENTER after it and go on

          or you can do this CString t = "Hello" "World"; without the '\' slash character

            Thanks. I never thought it was so simple. What a shame. What if I want to force it to make a newline? Newbies

              A new line in the text? Use \n, there's others too like \t for tab, \\ for '\', etc. Look these up (or 'escape sequences') in MSDN for more info

                Thanks I've look at MSDN and you were right. but when I want to type like this CString welcome_string = "Hello\ \n World"; so that Hello and World are in different line, there was a "newline is constant" error. :confused: Newbies

                          I'm afraid TextOut couldn't handle the "\n", but MessageBox() can. Try MessageBox(welcome_string); and see.

                                  As Lucy said, TextOut() can not handle newlines, but DrawText() can. If you want to output multi line text use DrawText(). HTH
