I want to draw text vertically  in CView::OnDraw,
How to realize it use CDC::DrawText or other WinApi?
for example:
    I
    w
    a
    n
    t
    t
    o

Hi,

if there isn't a flag for drawtext (i'm not sure, without looking)
you can set the drawing alignment for the font, in the font's structure.

This means your font needs constructing indirectly, or otherwise.
I reccommend you do this when your window becomes live.

So that you can cache it for the life of your CWnd derived object.
This way you don't slow the OnDraw down having to rebuild the font each
time.

Hope this helps,

Let me know,

Ian

     If that's really the way you want the text displayed--with each character
still displayed vertically, but with the text flowing top-to-bottom instead
of left-to-right--then I don't believe that there's any API routine that will
do that for you on the fly.  You'll need to write your own routine that
takes the string you want to display, modifies that string to put each
character to be displayed on a separate line (so "I want to" becomes
"I\r\n \r\nw\r\na\r\nn\r\nt\r\n \r\nt\r\no"), and calls DrawTextEx to display
that modified string.
     If you want the characters to be rotated 90 degrees as well--in other
words, if you want the string to look normal if you rotate your head by 90
degrees to read it--then you do that when you create the font.  For example,
this routine takes whatever font you give it, and returns a font with the same
typeface/size/other info, but that will display text that's rotated by 90
degrees:

CFont * MakeRotatedFont(CFont * pSourceFont)
{
    LOGFONT log;
    if (!pSourceFont->GetLogFont(&log))
        return NULL;
    log.lfEscapement = 900; // rotation, in tenths of degrees
    log.lfOrientation = 900; // same thing
    CFont * pFontToReturn = new CFont();
    if (pFontToReturn) {
        if (!(pFontToReturn->CreateFontIndirect(&log))) {
            delete pFontToReturn;
            return NULL;
        }
    }
    return pFontToReturn;

     Now, when you want to display top-to-bottom text, you would use this
rotated font.

     The normal response to this would be "If you expect others to take the
time to answer your question, you can take the time to read the answer here."
But I'm a soft touch sometimes. :)
