Created Issue: WlanClient.WlanInterface.queueEvents is not synchronized [14925]

NN — Thu, 19 Nov 2009 14:33:47 GMT

There is no synchronization for queueEvents.
It leads to problems because the check and the assignment are done in different threads.

You can set queueEvents to true but the event won't be called because it is not synchronized across the CPUs.

Possibly lock statement should be added.
It should be checked good.

Closed Issue: Make WlanClient IDisposable [14904]

ikonst — Thu, 19 Nov 2009 13:44:18 GMT

public class WlanClient : IDisposable
{
...
~WlanClient()
{
Close();
}

void IDisposable.Dispose()
{
GC.SuppressFinalize(this);
Close();
}

private void Close()
{
Wlan.WlanCloseHandle(clientHandle, IntPtr.Zero);
}
...
}

And then use it :
using(var wlanClient = new WlanClient())
{
} // WlanCloseHandle

Commented Issue: Unhandled Exception in OnWlanNotification [14284]

ikonst — Thu, 19 Nov 2009 13:41:25 GMT

This is a Low priority issues as it only happens after my code has been running most of the day.
In the Wlan.WlanNotificationCodeAcm.ScanFail case the following line fails on occasion
int expectedSize = Marshal.SizeOf(typeof (Wlan.WlanReasonCode));
With something Like it cannot find the size of the unmanaged code. I will update with an exact error the next time it happens

Commented Issue: Unhandled Exception in OnWlanNotification [14284]

SkiGeek — Tue, 06 Oct 2009 17:21:13 GMT

Here is the error
Type 'NativeWifi.Wlan+WlanReasonCode' cannot be marshaled as an unmanaged structure; no meaningful size or offset can be computed.

It seems to happen on occasion when the computer resumes from standby.
I am creating an application that runs in the background and monitors the internet connection and reconnects when disconnected and logins to a gateway redirect page. (The host bumps you off fairly often) On Vista OS this requires you to disconnect and reconnect the WiFi.

Closed Issue: dot11CipherAlgorithm issues

ikonst — Wed, 01 Jul 2009 12:52:09 GMT

The dot11CipherAlgorithm doesnt appear to enumerate the correct Cypher algoirthm. It brings back CCMP (AES) when Im using TKIP and the dot11AuthAlgorithm doesnt appear to enumerate any auth protocol when Im using WPA-PSK, it just returns 0.

Below is the code Im using as a test from a client

NativeWifi.WlanClient oWlan = new NativeWifi.WlanClient();
Console.WriteLine(oWlan.Interfaces[0].CurrentConnection.wlanSecurityAttributes.dot11AuthAlgorithm.ToString());
Console.WriteLine(oWlan.Interfaces[0].CurrentConnection.wlanSecurityAttributes.dot11CipherAlgorithm.ToString());
Comments:

I've fixed it in the source code, so try the latest.

COMMENTED ISSUE: Implement scanning for available networks

nsekkeli — Wed, 30 Jan 2008 11:35:20 GMT

Implement scanning for available networks.

Support snippet:
---
Yes, that's true - GetProfiles is not the right way to go. You should use WlanClient's Scan method. The clumsy thing about Scan is that it's asynchronous: it returns immediately, and then you should get an event (you can subscribe to one of WlanClient's events, not sure which...) and only once you get the ScanComplete notification code, only then you can call WlanGetAvailableNetworkList...

- but guess what, I didn't include this method yet. So maybe it isn't ready for version 1.0 yet ...

I'll try to cover this basic feature (scanning) ASAP.
Comments: ** Comment from web user: nsekkeli **

First of all i want to thank you for such a useful job. Like raja286, i am trying to find the MAC address of the available AP's. Is it possible in released version? Or does windows API give opportunity to reach this info? Can you help me?

Thanks

CREATED ISSUE: Example code, pls.

Hi,
Thanks for your project, I 've been looking for such a wrapper to WZC for a while.
Anyway, I'm kind of new with .net and I don't really understand how to use your api.
I need to scan for the available SSID (only the name ..) and get an array of these strings.

how can I do such a thing?
I will be more then happy if you could give me an example ,

Regards,
Dan.

The managed API for this is already in the source code (not released yet but you can get it).
Unfortunately the ScanComplete notification is not available on Windows XP SP2, so I cannot implement a ScanSynchronously method for now. However, most times, GetAvailableNetworkList on the WlanInterface would work just fine.

COMMENTED ISSUE: dot11CipherAlgorithm issues

ikonst — Sun, 14 Oct 2007 17:25:56 GMT

Ok, there was an incorrect definition of the WLAN_ASSOCIATION_ATTRIBUTES struct in MSDN, which caused the rest of the attributes to slide a bit. I've fixed it in the source code, so try the latest.

raja286 — Tue, 24 Jul 2007 17:43:21 GMT

I am also looking for example code in c# that implements the scanning of AP's MAC address and RSSI. Would it be possible with the API that you have provided and if so can you give an example code. I shall be very thankful.
