The time stealer seems to be the opening and closing of the file for every log entry. But I cannot simply open it once and never close it, because the log entrys are only put into the file with the close() call.

// Add a line of text to the Log
void Logger::LogThis(CString Text)
{
    SYSTEMTIME cur_time;
	CString t1;
	CString t2;
	DWORD dwBytesWritten;

	if (Folder.IsEmpty() || Prefix.IsEmpty())
	{
		TRACE("Log Location Not Set");
		return;
	}
	Lock();													// force single file to the log file
    GetLocalTime(&cur_time);
	t1.Format("%02d-%02d-%04d %02d:%02d:%02d : %.200s\r\n",
		      cur_time.wMonth, cur_time.wDay, cur_time.wYear,
		      cur_time.wHour, cur_time.wMinute, cur_time.wSecond, Text);
	t2.Format("%s%s%04d%02d%02d.log", Folder, Prefix, cur_time.wYear, cur_time.wMonth, cur_time.wDay);
	HANDLE hAppend = CreateFile(t2,	// open log file
			FILE_APPEND_DATA,		// open for writing
			FILE_SHARE_READ,		// allow multiple readers
			NULL,				// no security
			OPEN_ALWAYS,			// open or create
			FILE_ATTRIBUTE_NORMAL,	// normal file
			NULL);				// no attr. template
	if (hAppend != INVALID_HANDLE_VALUE)
	{
		SetFilePointer(hAppend, 0, NULL, FILE_END);
		WriteFile(hAppend, (LPCTSTR)t1, t1.GetLength(), &dwBytesWritten, NULL);
		CloseHandle(hAppend);
	}
	Unlock();												// OK, file is ready for the next guy
}

TheLogFile = new Logger();
TheLogFile->SetFolder("Log\\");
TheLogFile->SetPrefix("UpdateProcess");

Btw, are CreateFile() and WriteFile() significantly different from what I do? Ofstream open() and '<<' ?

Thanks for your replay. But I need to get check box event selection message handler not whether check box is checked or not.

I have used both LVN_ITEMCHANGING and LVN_ITEMCHANGED . But these these are sent not only for check box selection but also for another events like adding items to Listctrl.
