算法测试平台搭建常用代码备份

最近要在windows平台下搭建一个简单的算法测试平台进行算法的测试（又要做windows下算法的开发~）

故而把一些常用的MFC代码的的代码总结如下

选择路径对话框

void CMuraDetectDlg::OnMenuChoosePath(){    // TODO:  在此添加命令处理程序代码    wchar_t szPath[MAX_PATH] = {0};    BROWSEINFO bi;    bi.hwndOwner = m_hWnd;    bi.pidlRoot  = NULL;    bi.lpszTitle = _T("请选择需要打包的目录：");    bi.ulFlags   = 0;    bi.lpfn      = NULL;    bi.lParam    = 0;    bi.iImage    = 0;    bi.pszDisplayName = szPath;    //弹出选择目录对话框    LPITEMIDLIST lp = SHBrowseForFolder(&bi);    if (lp && SHGetPathFromIDList(lp, szPath))    {        CString str;        str.Format(_T("选择的目录为 %s"), szPath);        AfxMessageBox(str);    }    else    {        AfxMessageBox(_T("无效的目录，请重新选择"));    }    m_file_path = m_util.UnicodeToANSI(szPath);}

MFC下各种编码格式的转换

// ANSI to Unicodewstring CUtil::ANSIToUnicode(const string& str){    int  len = 0;    len = str.length();    int  unicodeLen = ::MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, NULL, 0);    wchar_t *  pUnicode;    pUnicode = new  wchar_t[unicodeLen + 1];    memset(pUnicode, 0, (unicodeLen + 1)*sizeof(wchar_t));    ::MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, (LPWSTR)pUnicode, unicodeLen);    wstring  rt;    rt = (wchar_t*)pUnicode;    delete  pUnicode;    return  rt;}//Unicode to ANSIstring CUtil::UnicodeToANSI(const wstring& str){    char*     pElementText;    int    iTextLen;    // wide char to multi char    iTextLen = WideCharToMultiByte(CP_ACP,        0,        str.c_str(),        -1,        NULL,        0,        NULL,        NULL);    pElementText = new char[iTextLen + 1];    memset((void*)pElementText, 0, sizeof(char)* (iTextLen + 1));    ::WideCharToMultiByte(CP_ACP,        0,        str.c_str(),        -1,        pElementText,        iTextLen,        NULL,        NULL);    string strText;    strText = pElementText;    delete[] pElementText;    return strText;}// UTF - 8 to Unicodewstring CUtil::UTF8ToUnicode(const string& str){    int  len = 0;    len = str.length();    int  unicodeLen = ::MultiByteToWideChar(CP_UTF8,        0,        str.c_str(),        -1,        NULL,        0);    wchar_t *  pUnicode;    pUnicode = new  wchar_t[unicodeLen + 1];    memset(pUnicode, 0, (unicodeLen + 1)*sizeof(wchar_t));    ::MultiByteToWideChar(CP_UTF8,        0,        str.c_str(),        -1,        (LPWSTR)pUnicode,        unicodeLen);    wstring  rt;    rt = (wchar_t*)pUnicode;    delete  pUnicode;    return  rt;}// Unicode to UTF - 8string CUtil::UnicodeToUTF8(const wstring& str){    char*     pElementText;    int    iTextLen;    // wide char to multi char    iTextLen = WideCharToMultiByte(CP_UTF8,        0,        str.c_str(),        -1,        NULL,        0,        NULL,        NULL);    pElementText = new char[iTextLen + 1];    memset((void*)pElementText, 0, sizeof(char)* (iTextLen + 1));    ::WideCharToMultiByte(CP_UTF8,        0,        str.c_str(),        -1,        pElementText,        iTextLen,        NULL,        NULL);    string strText;    strText = pElementText;    delete[] pElementText;    return strText;}

获取指定文件夹下所有的指定格式的文件
这里用到了boost，自从做服务器开发用到了boost，就离不开了，什么功能都想直接用boost，果然有毒呀！！

int CUtil::get_path_allfiles(const std::string& dir, const std::string fmt, bool mult_layer, std::vector<std::string>& filenames){    filesystem::path path(dir);    if (!filesystem::exists(path))    {        return -1;    }    filesystem::directory_iterator end_iter;    for (filesystem::directory_iterator iter(path); iter != end_iter; ++iter)    {        if (filesystem::is_regular_file(iter->status()))        {            string tmp_name = iter->path().string();            if (tmp_name.size() < 4)            {                continue;            }            tmp_name = tmp_name.substr(tmp_name.size() - 4, 4);            if (tmp_name.compare(fmt) == 0)            {                filenames.push_back(iter->path().string());            }        }        if (filesystem::is_directory(iter->status()))        {            if (mult_layer)            {                get_path_allfiles(iter->path().string(), fmt, mult_layer, filenames);            }        }    }    return (int)filenames.size();}
