1、浏览文件夹并记住上次选择目录

static TCHAR szDir[MAX_PATH] ;int CALLBACK BrowseCallbackProc(HWND hwnd,UINT uMsg,LPARAM lParam,LPARAM lpData)  {LPITEMIDLIST tmp = (LPITEMIDLIST)lParam;switch (uMsg){case BFFM_INITIALIZED:SendMessage(hwnd, BFFM_SETSELECTION, TRUE, (LPARAM)lpData);break;case BFFM_SELCHANGED:TCHAR buffer[MAX_PATH];if (SHGetPathFromIDList((LPITEMIDLIST) tmp ,buffer)){SendMessage(hwnd,BFFM_SETSTATUSTEXT,0,(LPARAM)buffer);}break;default:break;}return 0;  }void OnBnClicked(UINT id){// TODO: 在此添加控件通知处理程序代码BROWSEINFO bi;memset(&bi, 0 , sizeof(bi));TCHAR Buffer[MAX_PATH] = {0};bi.hwndOwner = NULL;bi.pidlRoot =NULL;//初始化制定的root目录很不容易bi.pszDisplayName = Buffer;//此参数如为NULL则不能显示对话框bi.lpszTitle = _T("选择文件路径");bi.ulFlags = BIF_STATUSTEXT;//包括文件bi.lpfn = BrowseCallbackProc;bi.iImage=IDR_MAINFRAME;bi.lParam = (LPARAM)szDir;//初始化入口参数bi结束LPITEMIDLIST pIDList = SHBrowseForFolder(&bi);//调用显示选择对话框if(pIDList){SHGetPathFromIDList(pIDList, Buffer);memcpy(szDir, Buffer, MAX_PATH);switch (id){case IDC_INPUT:m_strInput = Buffer;break;case IDC_OUTPUT:m_strOutput = Buffer;break;default:break;}UpdateData(FALSE);}// free memory used     IMalloc * imalloc = 0;if ( SUCCEEDED(SHGetMalloc( &imalloc))){imalloc->Free (pIDList);imalloc->Release();}}

2、递归遍历目录下的文件

void RecursiveSearchDir(CString path){WIN32_FIND_DATA wData;memset(&wData, 0, sizeof(WIN32_FIND_DATA));CString strFind = path + _T("\\*.*");HANDLE hFind = FindFirstFile(strFind, &wData);if (INVALID_HANDLE_VALUE == hFind){return;}do {if (CString(wData.cFileName).CompareNoCase(_T(".")) && CString(wData.cFileName).CompareNoCase(_T(".."))){if (wData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY){RecursiveSearchDir(path + _T("\\") + wData.cFileName);}else{CString fileName(path + _T("\\") + wData.cFileName);m_vecInput.push_back(fileName);}}} while ( FindNextFile(hFind, &wData));}
