Is there an equivalent function in NLM interface for InternetCheckConnection?
The NLM (Network List Manager) interface in Windows provides a set of functions for managing and monitoring network connections. However, there is no direct equivalent function to InternetCheckConnection
in the NLM interface.
InternetCheckConnection
is a WinINet function used to check the availability of an internet connection. It is specifically designed for internet connectivity checks.
In the NLM interface, you can monitor the network connectivity status using the INetworkConnectionEvents
interface and the INetworkConnection
interface. These interfaces allow you to receive notifications when the network connection status changes. However, they do not provide a dedicated function for checking internet connectivity.
To check internet connectivity using the NLM interface, you can combine it with other techniques such as sending a ping request or making a simple HTTP request to a known server. Here's an example using PowerShell and the Invoke-WebRequest
cmdlet to check internet connectivity:
powershelltry {
$response = Invoke-WebRequest -Uri "https://www.example.com" -UseBasicParsing -TimeoutSec 5
if ($response.StatusCode -eq 200) {
Write-Host "Internet connectivity is available."
} else {
Write-Host "Internet connectivity is not available."
}
} catch {
Write-Host "Internet connectivity is not available."
}
In this example, the Invoke-WebRequest
cmdlet is used to make a simple HTTP request to "https://www.example.com". If the request succeeds and returns a status code of 200 (OK), it indicates that internet connectivity is available.
Remember to adjust the URL and timeout value according to your needs.
Note that this approach relies on making an external request to determine internet connectivity, and it may be subject to firewalls, proxy settings, or other network configurations.
