Question

VC++6.0 写的代码太小了符号都看不清 怎么改变字体的大小？

Answer 1

利用CFont类的成员函数，CreateFont()和SetFont()函数，具体可参见MSDN
CFont Seg7Font;
CEditColor m_PressureWnd;
CEditColor m_TemperWnd;

CDC* pDC = GetDC();
Seg7Font.CreateFont(-MulDiv(2,-pDC->GetDeviceCaps(LOGPIXELSY), 6),
0,0,0,FW_NORMAL,0,0,0,ANSI_CHARSET,
OUT_STROKE_PRECIS,CLIP_STROKE_PRECIS,DRAFT_QUALITY,
VARIABLE_PITCH|FF_SWISS,_T("NI7SEG"));

m_PressureWnd.SetFont(&Seg7Font);
m_TemperWnd.SetFont(&Seg7Font);

CharFont.CreateFont(-MulDiv(2,-pDC->GetDeviceCaps(LOGPIXELSY), 6),
0,0,0,FW_NORMAL,0,0,0,ANSI_CHARSET,
OUT_STROKE_PRECIS,CLIP_STROKE_PRECIS,DRAFT_QUALITY,
VARIABLE_PITCH|FF_SWISS,_T("Airial"));

m_StaticP.SetFont(&CharFont);
m_StaticT.SetFont(&CharFont);
m_StaticC.SetFont(&CharFont);

可以设置系统字体大小吧
