Did you also see that without GM_ADVANCDED lfOrientation will not have any
effect on the font?

Yes, the problem was that the change for the 2700 had not yet been
compiled because I had
actually put some conditional compilation around it; then when I moved it
to my laptop I'd
fixed that, but had not moved it back. So I took out the #ifdef when I
made this copy
from the main development machine. Sigh. I'd forgotten that I'd
misremembered the field
name (which I'd fixed a week ago on the laptop version). I've now moved
it all back onto
the main machine, and indeed it is lf.lfOrientation.

I've got to update the Font Explorer (that was also on my ToDo List for
the San Diego
trip, but I ended up working on an Earth Day presentation, and a guest
lecture for the CMU
Operating Systems class, and a story, instead). It shows all this quite
nicely. But it
is very creaky around the edges, having been written in 1996, and I want
to bring it up to
2008 standards before I re-release it.

Joe,
Please post code that will compile. ;)

if(f.lfRotation == 2700)
x = r.Width();

should that be?

if(lf.lfOrientation == 2700)
x = r.Width();

Anyway, yes you are right, if you want to simply rotate the text, but
don't
care about the orientation of the characters then you don't need
GM_ADVANCED. So with your code, change the lfOrientation to 0 or
whatever
number you like, and you will see that the output will still be exactly
the
same.

But if you want the dc to take the Orientation into account then you will
need GM_ADVANCED.

Actually, no. If we could post images on the NG, I'd show an example of
a
rotated font
that does not use GM_ADVANCED. I rotated it both 90 and 270, to create
a
vertical label
for a pair of slider controls, and the code is as shown below.

The font I'm using is

"MS Shell Dlg 2"

but I get that from the font that is established when the dialog is
created.

The setup was in the OnInitDialog of the dialog containing the control:

  CRotatedText x_Eye;

   CFont * f = GetFont();
   LOGFONT lf;
   f->GetLogFont(&lf);
   lf.lfEscapement = 900;
   lf.lfOrientation = 900;
   Vertical90.CreateFontIndirect(&lf);
   x_Height.SetFont(&Vertical90);

   lf.lfEscapement = 2700;
   lf.lfOrientation = 2700;
   Vertical270.CreateFontIndirect(&lf);
   x_Eye.SetFont(&Vertical270);

and the class is derived from CStatic:

class CRotatedText : public CStatic
{
DECLARE_DYNAMIC(CRotatedText)

public:
CRotatedText();
virtual ~CRotatedText();

protected:
DECLARE_MESSAGE_MAP()
public:
   afx_msg void OnPaint();
   afx_msg void OnSize(UINT nType, int cx, int cy);
};

void CRotatedText::OnPaint()
   {
    CPaintDC dc(this); // device context for painting
    CRect r;
    GetClientRect(&r);
    dc.FillSolidRect(&r, ::GetSysColor(COLOR_3DFACE));
    dc.SetTextAlign(TA_CENTER);
    CFont * f = GetFont();
    LOGFONT lf;
    f->GetLogFont(&lf);

    int x = 0;
    if(f.lfRotation == 2700)
       x = r.Width();

    dc.SelectObject(f);

    CString s;
    GetWindowText(s);
    dc.TextOut(x, r.Height() / 2, s);
    // Do not call CStatic::OnPaint() for painting messages
   }

I discovered it wasn't properly updating when it was resized:

void CRotatedText::OnSize(UINT nType, int cx, int cy)
   {
    CStatic::OnSize(nType, cx, cy);

    Invalidate();
   }

You have to set the drawing mode to GM_ADVANCED for the Orientation to
work.

Here is an example:

Here is a thread from last week about the same question:

I cannot get my text to display vertically :-(

void CTestApp::OnDrawCDC* pDC)
{
CDC dcMem;
dcMem.CreateCompatibleDC(pDC);
pDC->SetBkColor(RGB(255,255,255));
CMemDC pDC(dc);

LOGFONT lfNew;
ZeroMemory (&lfNew, sizeof(LOGFONT));
lfNew.lfHeight = 100;
lfNew.lfWeight = FW_NORMAL;
lfNew.lfOrientation = lfNew.lfEscapement = 2700;
wcscpy(lfNew.lfFaceName, _T("MS Sans Serif"));
CFont Font;
Font.CreateFontIndirect(&lfNew);
pDC->SelectObject(&Font);

pMEMDC->TextOut(200, 200, _T("Hello World"));
....
}
