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;
