11. 如何判断当前操作系统的版本

//------------------------------------------------------------------------------------------------

//判断操作系统涵数及变量

typedef enum tagWin32SysType{
Windows32s,
WindowsNT3,
Windows95,
Windows98,
WindowsME,
WindowsNT4,
Windows2000,
WindowsXP
}Win32SysType;

//判断操作系统涵数及变量，jingzhou xu

Win32SysType IsShellSysType()
{
Win32SysType  ShellType;
DWORD winVer;
OSVERSIONINFO *osvi;

winVer=GetVersion();

if(winVer<0x80000000){/*NT */
      ShellType=WindowsNT3;
      osvi= (OSVERSIONINFO *)malloc(sizeof(OSVERSIONINFO));
      if (osvi!=NULL){
         memset(osvi,0,sizeof(OSVERSIONINFO));
         osvi->dwOSVersionInfoSize=sizeof(OSVERSIONINFO);
         GetVersionEx(osvi);
         if(osvi->dwMajorVersion==4L)ShellType=WindowsNT4;
         else if(osvi->dwMajorVersion==5L&&osvi->dwMinorVersion==0L)ShellType=Windows2000;
         else if(osvi->dwMajorVersion==5L&&osvi->dwMinorVersion==1L)ShellType=WindowsXP;
         free(osvi);
      }
}
else if  (LOBYTE(LOWORD(winVer))<4)
      ShellType=Windows32s;
else{
      ShellType=Windows95;
      osvi= (OSVERSIONINFO *)malloc(sizeof(OSVERSIONINFO));
      if (osvi!=NULL){
         memset(osvi,0,sizeof(OSVERSIONINFO));
         osvi->dwOSVersionInfoSize=sizeof(OSVERSIONINFO);
         GetVersionEx(osvi);
         if(osvi->dwMajorVersion==4L&&osvi->dwMinorVersion==10L)ShellType=Windows98;

  DeleteDC(hMemDC1);
  DeleteDC(hMemDC2);

  ::ReleaseDC(m_hWnd, hMainDC);

}

15. 如何建立一个灰度级图标

HICON CreateGrayscaleIcon(HICON hIcon)
{
  HICON    hGrayIcon = NULL;
  HDC       hMainDC = NULL,
            hMemDC1 = NULL,
            hMemDC2 = NULL;
  BITMAP    bmp;
  HBITMAP    hOldBmp1 = NULL,
            hOldBmp2 = NULL;
  ICONINFO csII, csGrayII;
  BOOL       bRetValue = FALSE;

  bRetValue = ::GetIconInfo(hIcon, &csII);

  if (bRetValue == FALSE) return NULL;

  hMainDC = ::GetDC(m_hWnd);
  hMemDC1 = ::CreateCompatibleDC(hMainDC);
  hMemDC2 = ::CreateCompatibleDC(hMainDC);
  if (hMainDC == NULL ||
hMemDC1 == NULL ||
hMemDC2 == NULL)
   return NULL;

  if (::GetObject(csII.hbmColor,
            sizeof(BITMAP), &
            amp;bmp))
  {
csGrayII.hbmColor =
      ::CreateBitmap(csII.xHotspot*2,
                     csII.yHotspot*2,
                     bmp.bmPlanes,
                     bmp.bmBitsPixel,
                     NULL);
if (csGrayII.hbmColor)
{
   hOldBmp1 =
      (HBITMAP)::SelectObject(hMemDC1,
                              csII.hbmColor);
   hOldBmp2 =
      (HBITMAP)::SelectObject(hMemDC2,
                              csGrayII.hbmColor);

   ::BitBlt(hMemDC2, 0, 0, csII.xHotspot*2,
            csII.yHotspot*2, hMemDC1, 0, 0,
            SRCCOPY);

   DWORD dwLoopY = 0, dwLoopX = 0;
   COLORREF crPixel = 0;
   BYTE    byNewPixel = 0;
   for (dwLoopY = 0; dwLoopY < csII.yHotspot*2; dwLoopY++)
   {
      for (dwLoopX = 0; dwLoopX < csII.xHotspot*2; dwLoopX++)
      {
      crPixel = ::GetPixel(hMemDC2, dwLoopX, dwLoopY);
      byNewPixel = (BYTE)((GetRValue(crPixel) * 0.299) +
            (GetGValue(crPixel) * 0.587) +
            (GetBValue(crPixel) * 0.114));
      if (crPixel) ::SetPixel(hMemDC2,
                              dwLoopX,
                              dwLoopY,
                              RGB(byNewPixel,
                              byNewPixel,
                              byNewPixel));
   } // for
   } // for
   ::SelectObject(hMemDC1, hOldBmp1);
   ::SelectObject(hMemDC2, hOldBmp2);

   csGrayII.hbmMask = csII.hbmMask;
   csGrayII.fIcon = TRUE;
   hGrayIcon = ::CreateIconIndirect(&csGrayII);
} // if
:

eleteObject(csGrayII.hbmColor);
//:

eleteObject(csGrayII.hbmMask);
} // if
:

eleteObject(csII.hbmColor);
  ::DeleteObject(csII.hbmMask);
  ::DeleteDC(hMemDC1);
  ::DeleteDC(hMemDC2);
  ::ReleaseDC(m_hWnd, hMainDC);

  return hGrayIcon;
}

16. 如何按指定角度旋转显示内存位图(用法和BitBlt类似)

void RotBlt(HDC destDC, int srcx1, int srcy1, int srcx2, int srcy2,

  HDC srcDC , int destx1, int desty1 ,int thetaInDegrees ,DWORD mode)
{
  double theta = thetaInDegrees * (3.14159/180);

  //原图像原始大小

  int width = srcx2 - srcx1;
  int height = srcy2 - srcy1;

  //原图像中心点
  int centreX = int(float(srcx2 + srcx1)/2);
  int centreY = int(float(srcy2 + srcy1)/2);

  //判断出图像可以沿任意方向旋转的矩形框
  if(width>height)height = width;
  else
width = height;

  HDC memDC = CreateCompatibleDC(destDC);
  HBITMAP memBmp = CreateCompatibleBitmap(destDC, width, height);

  HBITMAP obmp = (HBITMAP) SelectObject(memDC, memBmp);

  //内存DC新在中心点

  int newCentre = int(float(width)/2);
  //开始旋转
  for(int x = srcx1; x<=srcx2; x++)
for(int y = srcy1; y<=srcy2; y++)
{
   COLORREF col = GetPixel(srcDC,x,y);
   int newX = int((x-centreX)*sin(theta)+(y-centreY)*cos(theta));
   int newY = int((x-centreX)*cos(theta)-(y-centreY)*sin(theta));
   SetPixel(memDC , newX + newCentre, newY + newCentre, col);
}

  //复制到目标DC上
  BitBlt(destDC, destx1, desty1, width, height, memDC, 0,0,mode);
  //释放内存
  SelectObject(memDC, obmp);
  DeleteDC(memDC);
  DeleteObject(memBmp);
}

用法：

RotBlt(dc, 0,0,150,150,memDC,200,0, 45, SRCCOPY);

17. 如何将指定的窗体，以位图形式复制到系统剪切板上

void CScreenSnapDlg::toClipboard_Bio(CWnd * wnd, BOOL FullWnd)
{
   CDC *dc;
   if(FullWnd)
      { /* 抓取整个窗口 */
      dc = new CWindowDC(wnd);
      } /* 抓取整个窗口 */
   else
      { /* 仅抓取客户区时 */
      dc = new CClientDC(wnd);
      } /* 仅抓取客户区时 */

   CDC memDC;
   memDC.CreateCompatibleDC(dc);

   CBitmap bm;
   CRect r;
   if(FullWnd)
      wnd->GetWindowRect(&r);
   else
      wnd->GetClientRect(&r);

   CString s;
   wnd->GetWindowText(s);
   CSize sz(r.Width(), r.Height());

   bm.CreateCompatibleBitmap(dc, sz.cx, sz.cy);
   CBitmap * oldbm = memDC.SelectObject(&bm);
   memDC.BitBlt(0, 0, sz.cx, sz.cy, dc, 0, 0, SRCCOPY);

   //直接调用OpenClipboard()，而不用wnd->GetParent()->OpenClipboard();
   wnd->OpenClipboard();
   ::EmptyClipboard();
   ::SetClipboardData(CF_BITMAP, bm.m_hObject);
   CloseClipboard();

   //恢复原始环境
   memDC.SelectObject(oldbm);
   bm.Detach();
   delete dc;
}

18. 如何替换HBITMAP中的颜色值

#define COLORREF2RGB(Color) (Color & 0xff00) | ((Color >> 16) & 0xff) \
                                          | ((Color << 16) & 0xff0000)

HBITMAP ReplaceColor (HBITMAP hBmp,COLORREF cOldColor,COLORREF cNewColor)
{
HBITMAP RetBmp=NULL;
if (hBmp)
{
      HDC BufferDC=CreateCompatibleDC(NULL);       // 源位图DC
      if (BufferDC)
      {
         SelectObject(BufferDC,hBmp); 　 // 选入DC中
         HDC DirectDC=CreateCompatibleDC(NULL);    // 目标DC
         if (DirectDC)
         {
            // 获取源位图大小
            BITMAP bm;
            GetObject(hBmp, sizeof(bm), &bm);

            // 初始化BITMAPINFO信息，以便使用CreateDIBSection
            BITMAPINFO RGB32BitsBITMAPINFO;
            ZeroMemory(&RGB32BitsBITMAPINFO,sizeof(BITMAPINFO));
            RGB32BitsBITMAPINFO.bmiHeader.biSize=sizeof(BITMAPINFOHEADER);
            RGB32BitsBITMAPINFO.bmiHeader.biWidth=bm.bmWidth;
            RGB32BitsBITMAPINFO.bmiHeader.biHeight=bm.bmHeight;
            RGB32BitsBITMAPINFO.bmiHeader.biPlanes=1;
            RGB32BitsBITMAPINFO.bmiHeader.biBitCount=32;

            UINT * ptPixels;
            HBITMAP DirectBitmap= CreateDIBSection(DirectDC,
                     (BITMAPINFO *)&RGB32BitsBITMAPINFO,
                     DIB_RGB_COLORS,(void **)&ptPixels, NULL, 0);
            if (DirectBitmap)
            {
                  HGDIOBJ PreviousObject=SelectObject(DirectDC, DirectBitmap);
                  BitBlt(DirectDC,0,0,bm.bmWidth,bm.bmHeight,BufferDC,0,0,SRCCOPY);

                  // 转换 COLORREF 为 RGB
                  cOldColor=COLORREF2RGB(cOldColor);
                  cNewColor=COLORREF2RGB(cNewColor);
                  // 替换颜色
                  for (int i=((bm.bmWidth*bm.bmHeight)-1);i>=0;i--)
                  {
                     if (ptPixels==cOldColor) ptPixels=cNewColor;  }2 V3 y: f( N' \7 m4 s; m- J! k# A
