Re: Switching between main SDI app windows

It works for me Lynn, though it forced me through the passport (aka
Live ID) signon to see it.


Yep that's it.


Here it is. Originally posted by "Ted:

Windows Vista has a new standard user interface font, Segoe UI 9
point, which is not given to you by the operating system when creating
a dialog with MS Shell Dlg. Ideally you would like to have your MFC
dialogs look modern when running on Windows Vista. That means changing
all your fonts to Segoe UI 9 point and/or having separate resources
for Vista if you want to work well on all platforms. Instead, there's
a cool trick you can use to avoid all that hassle.

The great thing about this solution is that you need not create a new
CDialog derived class. In fact the only code changes necessary are
those in your application's InitInstance function.

1) In the same file as your application's InitInstance function (just
above InitInstance) insert the following code:

#include <afxpriv.h>
#if _MSC_VER < 1300
#include <..\src\occimpl.h>
#else
#include "afxocc.h"
#endif

class CFontOccManager : public COccManager
{
public:
    CFontOccManager() { }

 virtual const DLGTEMPLATE* PreCreateDialog(_AFX_OCC_DIALOG_INFO*
pOccDialogInfo,
  const DLGTEMPLATE* pOrigTemplate);
};

void GetDisplayFont(LOGFONT &lf, WORD & wDefSize)
{
 NONCLIENTMETRICS ncm;
 ncm.cbSize = sizeof(NONCLIENTMETRICS);
 SystemParametersInfo(SPI_GETNONCLIENTMETRICS,
sizeof(NONCLIENTMETRICS), &ncm, 0);
 lf = ncm.lfMessageFont;

 HDC hDC = ::GetDC(NULL);
 if (lf.lfHeight < 0)
  lf.lfHeight = -lf.lfHeight;
 wDefSize = (WORD)MulDiv(lf.lfHeight, 72, GetDeviceCaps(hDC,
LOGPIXELSY));
 ::ReleaseDC(NULL, hDC);
}

const DLGTEMPLATE*
CFontOccManager::PreCreateDialog(_AFX_OCC_DIALOG_INFO* pOccDialogInfo,
 const DLGTEMPLATE* pOrigTemplate)
{
 const DLGTEMPLATE *lpNewTemplate = COccManager::PreCreateDialog
(pOccDialogInfo, pOrigTemplate);

 if ((BYTE)GetVersion() >= 6 && !pOccDialogInfo->m_pNewTemplate) {

  CDialogTemplate temp(lpNewTemplate);
  LOGFONT lf;
  WORD wDefSize = 0;
  GetDisplayFont( lf, wDefSize );
  temp.SetFont(lf.lfFaceName, wDefSize);

  pOccDialogInfo->m_pNewTemplate = (DLGTEMPLATE*) temp.Detach();
  return pOccDialogInfo->m_pNewTemplate;
 }
 else
  return lpNewTemplate;
}

2) In your InitInstance() function, change:

AfxEnableControlContainer();

to:

AfxEnableControlContainer(new CFontOccManager());

 (If you don't have a call to AfxEnableControlContainer already, just
add it as above)

That's it. Now your all your dialogs will use Segoe UI 9 point font
when running under Windows Vista, and will continue to use your
existing font under other platforms.

CPropertySheets/CPropertyPages are a bit more work, however I'll leave
that for another day (I posted some hints in the Vista UI Development
forum)
