HELP  WIN98(vxd)下文件及文件夹的隐藏实现方法？

安装文件系统钩子
然后处理IFSFN_FINDOPEN:
rval = (* ppPrevHook)(pfn, fn, Drive, ResType, CodePage, pir);
...
// 如果是要过滤得项
if (filtered)
{
rval = (* ppPrevHook)(pir->ir_hfunc->hf_read, IFSFN_FINDNEXT, Drive, ResType, CodePage, pir);
}

reutrn rval;


IFSFN_FINDNEXT:

rval = (* ppPrevHook)(pfn, fn, Drive, ResType, CodePage, pir);
...

if (filtered)
{
rval = MyIfsHookFunc(pfn, fn, Drive, ResType, CodePage, pir);
}

return rval;
