作如下处理：
            char *m_path;
            char pszDisplayName[MAX_PATH]; 
            BROWSEINFO BrowseInfo; 
            LPITEMIDLIST pidlBrowse; 
            LPMALLOC pMalloc; 
            if( !SUCCEEDED(SHGetMalloc(&pMalloc)) ) 
                return; 
            BrowseInfo.hwndOwner = m_hWnd; 
            BrowseInfo.pidlRoot = NULL; 
            BrowseInfo.pszDisplayName = pszDisplayName; 
            BrowseInfo.lpszTitle = "请指定路径"; 
            BrowseInfo.ulFlags = 0x40|BIF_RETURNONLYFSDIRS; //BIF_DONTGOBELOWDOMAIN; 
            BrowseInfo.lpfn = NULL; 
            BrowseInfo.lParam = 0; 
            BrowseInfo.iImage = 0; 
            pidlBrowse = SHBrowseForFolder(&BrowseInfo); 
            if( pidlBrowse!=NULL ) 
            { 
                if( SHGetPathFromIDList(pidlBrowse,pszDisplayName) ) 
                { 
                    m_path = pszDisplayName; 
                    //m_path += "\\"; 
                } 
                pMalloc->Free(pidlBrowse); 
            } 
            pMalloc->Release();
