CString Problerm

Zayax

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

CString welcome_string = "Hello\ \n**\** World";

oops, sorry, should be CString welcome_string = "Hello\n\ World";

Zayax

A lot of thanks for your reply:) BUT the output was Hello|World and not Hello World this was my code void CMyView::OnDraw(CDC* pDC) { CString welcome_string = "Hello\n\ World"; pDC->TextOut(0,0,welcome_string); } Newbies

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

;) I'm not sure. You'd better check that out.

Zayax

Thanks:rose: Is this means only messagebox can handle "\n"? How about editbox or listbox ia a dialog? Newbies

Zayax

:)Thanks Newbies

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