browseInfo.pszDisplayName=szDisplayName;
browseInfo.lpszTitle="请选择下载文件的存储路径";
browseInfo.ulFlags=BIF_RETURNFSANCESTORS|BIF_RETURNONLYFSDIRS;
browseInfo.lpfn=NULL;
browseInfo.lParam=0;

if((lpItemIDList=::SHBrowseForFolder(&browseInfo))!=NULL)
{
if(::SHGetPathFromIDList(lpItemIDList,szBuffer))

if(szBuffer[0]=='\0')
{
AfxMessageBox("Fail to get directory",MB_ICONSTOP|MB_OK);
return;
}
DownFileDirectory=szBuffer;
}

CString _BrowseForFolder(HWND hwnd = NULL, LPCTSTR lpszTitle = "请选择目录")
{
    char buf[MAX_PATH] = {0};
    BROWSEINFO bi;
    memset(&bi, 0, sizeof(BROWSEINFO));
    bi.hwndOwner = hwnd;
    bi.lpszTitle = lpszTitle;
    bi.ulFlags = BIF_RETURNONLYFSDIRS|BIF_EDITBOX|0x0040;
    
    LPITEMIDLIST pidl = SHBrowseForFolder(&bi);
    if(pidl)
    {
        LPMALLOC pMalloc;
        SHGetMalloc(&pMalloc);
        SHGetPathFromIDList(pidl, buf);
        pMalloc->Free(pidl);
        pMalloc->Release();
