编程必备:VC常用知识重温

这次我们将会带大家再次回顾一下VC的常用知识,包括得到系统时间日期(使用GetLocalTime)、分离字串等。

  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 a12;


  long x;


  for(int i = 0;i< (str.GetLength()/2);i++)


  {


  sscanf(str.Mid(2*i,2),%x,&x);


  a = 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);1


  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.center);


  strNum = strNum + strNum1;


  AfxMessageBox(strNum);


  7: 复制文件夹


  SHFILEOPSTRUCT Op;


  char FromBuf[]=E:temp;


  char ToBuf[]=SINTEKSERVER个人文档陈 伟;;


  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;


  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:


  MessageBox(hwnd,aaa,bbb,MB_OK);


  break;
