无法在 Excel VBA IP 列表 ping 中更改 ping 超时

Unable to change ping timeout in Excel VBA IP list ping

下面的代码在 Excel sheet 和 returns 响应时间和 TTL 中 ping 一个 IP 地址列表。根据 IP 地址的数量,超时可能会非常快地加起来并导致长时间等待。有没有办法添加 5​​00 毫秒的自定义超时?

根据 MSDN page on Win32_PingStatus,有一个名为 "Timeout"(以毫秒为单位)的 属性 可能会被更改。

尝试将您的查询更改为

"select * from Win32_PingStatus where TimeOut = 500 and address = '" & xCell & "'"

好像默认是1000毫秒
