TextOut 字符串输出

 在Windows 编程中可使用：

HWND m_hWnd = GetActiveWindow();
HDC hDC = GetDC(m_hWnd);
CString  str;
hDC.TextOut(x,y,str );
SetTextColor(hDC, RGB(255, 255, 255));   //设置字体颜色
SetBkMode(hDC, TRANSPARENT);//  设置背景为透明

CDC::TextOut

virtual BOOL TextOut(
   int x,
   int y,
   LPCTSTR lpszString,
   int nCount 
);
BOOL TextOut(
   int x,
      int y,
      const CString& str 
);

 TextOut

BOOL TextOut(
  HDC hdc,           // handle to DC
  int nXStart,       // x-coordinate of starting position
  int nYStart,       // y-coordinate of starting position
  LPCTSTR lpString,  // character string
  int cbString       // number of characters
);

 生成一个字体，再select         到设备环境中去弄

CFont font;
   font.CreateFont( 13,                                          //   nHeight   
     0,                                                   //   nWidth   
     0,                                                   //   nEscapement 
     0,                                                   //   nOrientation   
     FW_NORMAL,                                   //   nWeight   
     FALSE,                                           //   bItalic   
     FALSE,                                           //   bUnderline   
     0,                                                   //   cStrikeOut   
     ANSI_CHARSET,                             //   nCharSet   
     OUT_DEFAULT_PRECIS,                 //   nOutPrecision   
     CLIP_DEFAULT_PRECIS,               //   nClipPrecision   
     DEFAULT_QUALITY,                       //   nQuality   
     DEFAULT_PITCH   |   FF_SWISS,     //   nPitchAndFamily     
     _T("宋体"));
   hDC.SelectObject(&font);

CFont font;
font.CreatePointFont(120);
CFont* pOldFont = pDC->SelectObject(&font);
pDC->SelectObject(&font);
pDC->TextOut....
pDC->SelectObject(&pOldFont);
