  1: 得到系统时间日期(使用GetLocalTime)


  CString sTime,sYear,sMonth,sDay;
  SYSTEMTIME CurTime;
  GetLocalTime(&CurTime);
  sYear.Format("%d年",CurTime.wYear);
  sMonth.Format("%d月",CurTime.wMonth);
  sDay.Format("%d日",CurTime.wDay);
  sTime =  sYear+ sMonth + sDay;
  // CurTime.wHour
  // CurTime.wMinute
  // CurTime.wSecond IBM的
  AfxMessageBox(sTime);


  2: 分离字串


  CString str = "4d3f0a2278";
  unsigned char a[12];
  long x;
  for(int i = 0;i< (str.GetLength()/2);i++)
  {
  sscanf(str.Mid(2*i,2),"%x",&x);
  a[i] = x;
  }

  3: 得到当前目录 (GetCurrentDirectory)


  char  CurPath[MAX_PATH];
  DWORD size=MAX_PATH;
  GetCurrentDirectory(size,CurPath);
  AfxMessageBox(CurPath);
  
  //
  CString number;
  int len = LineLength(LineIndex(0));
  LPTSTR p=number.GetBuffer(len);
  this->GetLine(0,p,len);
  AfxMessageBox(number);
  得到系统目录 (GetSystemDirectory)

  4: 从字符串中提取数字


  CString strNum;
  CString str("测试125各国87kk");
  strNum = GetStr(str);
  AfxMessageBox(strNum);


  
  5: 创建无模对话框


  CDlg_Test *aa = new CDlg_Test;
  aa->Create(IDD_DIALOG1,NULL);
  aa->ShowWindow(SW_SHOW);

  6: 得到窗口绝对坐标


  CString strNum,strNum1;
  CRect rect;
  GetClientRect(&rect);
  ClientToScreen(&rect);
  strNum.Format("X: %d",rect.top);
  strNum1.Format("   Y: %d",rect.left);
  strNum = strNum + strNum1;
  AfxMessageBox(strNum);


  
  7: 复制文件夹


  SHFILEOPSTRUCT  Op;
  
  char FromBuf[]="E:\\temp\0";
  char ToBuf[]="\\\\SINTEKSERVER\\个人文档\\陈 伟\0";;
  
  Op.hwnd = NULL;
  Op.wFunc = FO_COPY;
  Op.pFrom = FromBuf;
  Op.pTo = ToBuf;
  Op.fFlags = FOF_NOCONFIRMATION | FOF_RENAMEONCOLLISION ;
  Op.fAnyOperationsAborted = FALSE;
  Op.hNameMappings = NULL;
  Op.lpszProgressTitle = NULL;
  
  if(SHFileOperation(&Op) == 0)
  MessageBox("复制完毕","提示",MB_OK|MB_ICONINFORMATION);

  8: 捕获 Ctrl+鼠标左键 组合


  case WM_LBUTTONDOWN://鼠标消息wParam ==
  if (wParam & MK_CONTROL)
  MessageBox(hwnd,"aaa","bbb",MB_OK);
  break;
  或
  case WM_LBUTTONDOWN:
  if(GetKeyState(VK_CONTROL)<0)
  MessageBox(hwnd,"aaa","bbb",MB_OK);
  break;
