我很乐意接受任何我可以直接自动化的解决方法(cmdline、wmi等)
或间接地
从VBA。(我使用的是64位Windows 7 Home和64位Office 365 Pro。)
netsh
,或下面的代码,但是
列表不刷新
除非我点击
-
名单上没有
根据某些文档的状态,每60秒自动更新一次。
-
断开+重新连接NIC
我想我是
没有得到控制
从
WlanOpenHandle
根据需要,我是绿色的C转换为VBA。
没有错误,但WlanScan返回未知代码
1168
.
的函数声明
VB
改编:
Public Shared Function WlanScan(ByVal hClientHandle As IntPtr, _
ByRef pInterfaceGuid As Guid, ByVal pDot11Ssid As IntPtr, _
ByVal pIeData As IntPtr, ByVal pReserved As IntPtr) As UInteger
End Function
函数用法
C#
:
Guid g;
//wlanHndl is the handle returned previously by calling [WlanOpenHandle]
for (int i = 0; i < infoList.dwNumberOfItems; i++)
{
g = infoList.InterfaceInfo[i].InterfaceGuid;
uint resultCode=WlanScan(wlanHndl, ref g, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero);
if (resultCode != 0)
return;
}
…和
如何打开手柄,在
C++
(来自
here
):
dwResult = WlanOpenHandle(dwMaxClient, NULL, &dwCurVersion, &hClient);
if (dwResult != ERROR_SUCCESS) {
wprintf(L"WlanOpenHandle failed with error: %u\n", dwResult);
return 1;
// You can use FormatMessage here to find out why the function failed
}

获取(缓存)无线网络列表:
很好用
-除了不能自己提神。(之前我正在解析
netsh wlan show networks mode=bssid
,也有同样的问题。)

当然有一种迂回的方法可以从VBA刷新网络列表吗?我对我可以自动化的解决方法很酷。。。有什么吗?!
