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.

To get results like this:

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:

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"));
....
}
