在 VisualC++ 的版本低于 4.0, MFC 必须自己实现
CPropertySheet。对于您 CPropertySheet 通过资源编辑器中设置首 CPropertyPage
您对话框资源的字体可能设置字体。在运行时, 表将使用字体设置并一切根据字体大小。开头 VisualC++4.0, MFC 使用
Windows 95 PropertySheet 控件。此控件将始终使用系统字体来表。这是设计使然。 MFC 还将强制页以用作表相同字体。
这样调用 BuildPropPageArray() 函数中。因为这是无出处函数, 它可能更改或将来的 MFC 版本中被删除。

CMySheet 将使用的首活动 CPropertyPage 字体来设置字体和 CPropertySheet 和其子窗口大小。 CPropertyPages 与资源编辑器中指定字体显示。

具体步骤：
1、新建类CMySheet，继承自CPropertySheet
2、在.cpp文件中大概实现如下。
3、修改.h文件。
4、使用这个CMySheet，更改资源中的属性页，则程序运行后，设置的字体有效。

#define WM_RESIZEPAGE WM_APP+1

// and also resizes everything according to the new font

你可以试试这样行吗？

怎样改变标题栏的宽度：

方法一：

NONCLIENTMETRICS ncm;
ncm.cbSize = sizeof( NONCLIENTMETRICS );

::SystemParametersInfo( SPI_GETNONCLIENTMETRICS,
sizeof( NONCLIENTMETRICS ),
&ncm,
0
);

ncm.lfCaptionFont.lfHeight = -300;
::SystemParametersInfo( SPI_SETNONCLIENTMETRICS,
sizeof( NONCLIENTMETRICS ),
&ncm,
SPIF_SENDCHANGE
);
　

方法二：

case WM_NCCALCSIZE:
{
BOOL bSpecial=FALSE;
int nEdgeWidth =3;
int nBarHeight =CAPTIONHEIGHT+3;
int nBottomEdge =3;

if(!(BOOL)wParam)
{
RECT rtSave;
CopyRect(&rtSave,(LPRECT)lParam);
// ::CallWindowProcA(lpwndinfo->pWndProc,hWnd,uMsg,wParam,lParam);

if(lpwndinfo->bIM ==TRUE)
{
int imbarheight =17;
rtSave.left+=nEdgeWidth;
rtSave.top+=imbarheight+3;
rtSave.right-=nEdgeWidth;
rtSave.bottom-=nBottomEdge;
}
else
{
rtSave.left+=nEdgeWidth;
rtSave.top+=nBarHeight;
rtSave.right-=nEdgeWidth;
rtSave.bottom-=nBottomEdge;
}
CopyRect((LPRECT)lParam,&rtSave);

*lResult=0;
::ReleaseDC(hWnd,hDC);
return TRUE;
}
else
{
RECT rtSave;
LPRECT prtClt;
LPNCCALCSIZE_PARAMS pNC;
pNC=(LPNCCALCSIZE_PARAMS)lParam;

prtClt=&(pNC->rgrc[0]);
CopyRect(&rtSave,prtClt);
CopyRect( &(pNC->rgrc[2]), &(pNC->rgrc[1]));

if(bSysDlg)
{
(pNC->rgrc[2]).left +=nEdgeWidth;
(pNC->rgrc[2]).right -=nEdgeWidth;
}
else
{
if(lpwndinfo->bIM ==TRUE)
{
int imbarheight =17;
(pNC->rgrc[2]).left +=nEdgeWidth;
(pNC->rgrc[2]).top +=imbarheight+3;
(pNC->rgrc[2]).right -=nEdgeWidth;
(pNC->rgrc[2]).bottom -=nBottomEdge;

rtSave.left+=nEdgeWidth;
rtSave.top+=imbarheight+3;
rtSave.right-=nEdgeWidth;
rtSave.bottom-=nBottomEdge;
}
else
{
(pNC->rgrc[2]).left+=nEdgeWidth;
(pNC->rgrc[2]).top+=nBarHeight;
(pNC->rgrc[2]).right-=nEdgeWidth;
(pNC->rgrc[2]).bottom-=nBottomEdge;
// Result=::CallWindowProcA(lpwndinfo->pWndProc,hWnd,uMsg,wParam,lParam);
//prtClt=&(pNC->rgrc[0]);
rtSave.left+=nEdgeWidth;
rtSave.top+=nBarHeight;
rtSave.right-=nEdgeWidth;
rtSave.bottom-=nBottomEdge;
}
}
CopyRect(prtClt,&rtSave);
*lResult=0;
::ReleaseDC(hWnd,hDC);
return TRUE;
}
break;
}
