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[]="c:\\a.txt";

char ToBuf[]="d:\\a.txt";;

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;
