VC常用知识

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;
