VS2010将图像以年月日时分秒命名

    CString strDir = _T("");
    GetPath(1,strDir);
    SYSTEMTIME tm;
    GetLocalTime(&tm);
    CString strTime;
    strTime.Format(_T("%04d%02d%02d-%02d%02d%02d-%03d"), tm.wYear,tm.wMonth, tm.wDay, 
    tm.wHour, tm.wMinute, tm.wSecond, tm.wMilliseconds);
    CString strPath = _T("./image_left/") + strTime + _T(".jpg");
    char cPath[MAX_PATH] = { 0 };
	strPath:string strDp=CStringA(strPath);
	size_t len=strDp.length()+1;
	size_t converted=0;
	wchar_t*WStr=(wchar_t*)malloc(len*sizeof(wchar_t));
	mbstowcs_s(&converted,WStr,len,strDp.c_str(),_TRUNCATE);
    int nAsciiLen = WideCharToMultiByte(CP_ACP, 0, WStr, -1, nullptr, 0, nullptr, nullptr);   
    WideCharToMultiByte(CP_ACP, 0, WStr, -1, cPath, nAsciiLen, nullptr, nullptr);

  

GetPath函数的作用是在没有文件夹的情况下创建文件夹。

void GetPath(int nCamera, CString &strPath){
    CString strDir = _T("./image_left/");
    if (nCamera == 2){
    strDir = _T("./image_right/");
 }
 //先判断路径是否存在，如果不存在则创建
   if (!PathIsDirectory(strDir)){
    ::CreateDirectory(strDir, NULL);
 }
   strPath = strDir; 
}
