IShellFolder浏览文件夹

这是由IShellFolder接口提供的浏览文件夹功能：

void SpecialFolder_Browse(HWND hwnd){LPMALLOC g_pMalloc;/* Gets the Shell's default allocator */if (::SHGetMalloc(&g_pMalloc) == NOERROR){BROWSEINFO bi; LPTSTR lpBuffer;LPITEMIDLIST pidlSpecialFolder;  // PIDL for Special FolderLPITEMIDLIST pidlBrowse;         // PIDL selected by user // Allocate a buffer to receive browse information. if ((lpBuffer = (LPTSTR) g_pMalloc->Alloc(MAX_PATH)) != NULL) { // Get the PIDL for the Programs folder. if (SUCCEEDED(SHGetSpecialFolderLocation(hwnd, CSIDL_DESKTOP/*CSIDL_DESKTOPDIRECTORY*/ , &pidlSpecialFolder))){ // Fill in the BROWSEINFO structure. bi.hwndOwner = hwnd; bi.pidlRoot = pidlSpecialFolder; bi.pszDisplayName = lpBuffer; bi.lpszTitle = _T("Choose a Program Group"); bi.ulFlags = 0; bi.lpfn = NULL; bi.lParam = 0; // Browse for a folder and return its PIDL. pidlBrowse = SHBrowseForFolder(&bi); if (pidlBrowse != NULL) {  // Show the display name, title, and file system path. ::MessageBox(hwnd, lpBuffer, L"Display name", MB_OK); if (SHGetPathFromIDList(pidlBrowse, lpBuffer)) //SHGetPathFromIDList获得pidlBrowse的全路径保存在缓存中 MessageBox(lpBuffer); // Free the PIDL returned by SHBrowseForFolder. g_pMalloc->Free(pidlBrowse); } // Clean up. g_pMalloc->Free(pidlSpecialFolder); }g_pMalloc->Free(lpBuffer); }// Release the shell's allocator.g_pMalloc->Release();}}
