常用VC小知识

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 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;   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;   
9、判断文件是否存在 CFileFind filefind; if(!filefind.FindFile(strFileName)) { MessageBox("DCM图象文件未找到!","友情提示",MB_OK|MB_ICONINFORMATION); return; }   
10、求平方和平方根函数 CString s; s.Format("%f",pow(3,2));//结果为9.000000,平方根为sqrt(double),不必include math.h AfxMessageBox(s);
11、设置画线颜色 CPen pen; pen.CreatePen(PS_DASH,iWeight,RGB(255,0,0));// 虚线,实线等多种风格 pDC->SelectObject(&pen); pDC->MoveTo(start.x,start.y); pDC->LineTo(end.x,end.y); pen.DeleteObject();
12、设置对话框窗口标题 void SetwindowText(LPCTSTR lpszString);
