I'm trying to make in C # to allow the data traffic of the Cellular device (wwan) when the user clicks disable or when the windows starts letting it as "disabled" (in case a problem) , however I can only enable / disable the device.(hardware) The problem is that when enabling the device, it will not necessarily connect if the user click "disable" the cell phone as shown in the image below.
Tried with, WMI Win32_NetworkAdapter
And also with the new class MSFT_NetAdapter
But on both I can only enable / disable the device. So if the customer accidentally clicked turned off, it doesn't automatically reconnect.
Figure 1 Has the enabled device but the cellular option is disabled
Figure 2 What I want is enable and disable the cellular option like picture above.
NOTE: I am in .net framework 4.8 because I am doing a service for Windows.
NOTE¹: I tried to use the Xamarin library which I know has the capacity for this, but without success.

How to enable cell phone traffic if the user has disabled it?
Tag: C #, C # Console
Microsoft has made a description on how to connect a mobile connection:
https://learn.microsoft.com/en-us/windows/iot-core/connect-your-device/mbb
and also released the code on github
https://github.com/ms-iot/iot-utilities/tree/master/MBBConnect
At least they invoke netsh mbn connect interface=Mobilfunk connmode=name name=GUID to connect the interface
To check state (enabled/disabled):
netsh mbn show radio interface=Mobilfunk
to enable:
netsh mbn set powerstate interface=Mobilfunk state=on
If I got your question correct then you can try this as well, make a service to check for the bellow registry Key value and change it accordingly.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WwanSvc\GroupPolicy
Dword:
DisableWwanAutoConnect
Set the value to 1

There is a sample on how to turn on / off the Wifi and Bluetooth, but not for Cellular connection: https://github.com/microsoft/Windows-universal-samples/tree/master/Samples/RadioManager
If you loop deeper, they are not available at the current version of Windows:

Im currently working on a Mobile application which connects to a Ble peripheral and reads data from it. In order to test if the connection is working. I have written a small C# application that utilizes the RaspberryPi4 bluetooth via DBus with BlueZ.
Everything works except that when connecting to iOS a pairing request is issued by the raspberry, eventhough I do not have any encrypted characteristics.
I have read on the Apple forum that this is because bluetoothd is automaticly trying to read the battery level of the phone. But sadly even after the fix suggested there I get the pairing requests.
Does anyone have an idea how I could fix this?
Thanks in advance
I believe disabling this bluez config option in /etc/bluetooth/main.conf would prevent the pi from trying to read characteristics from the iOS device, if that is the issue:
# Do reverse service discovery for previously unknown devices that connect to
# us. For BR/EDR this option is really only needed for qualification since the
# BITE tester doesn't like us doing reverse SDP for some test cases, for LE
# this disables the GATT client functionally so it can be used in system which
# can only operate as peripheral.
# Defaults to 'true'.
#ReverseServiceDiscovery = true
Check the connection min and max intervals, they shall be compliant with the iOS guidelines: https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf (page 180 - 40.6 Connection Parameters).
You can tune them like this:
echo "30" > /sys/kernel/debug/bluetooth/hci0/conn_min_interval
echo "45" > /sys/kernel/debug/bluetooth/hci0/conn_min_interval
The default values worked for me: [24,40]
Our company uses Cisco telephony. And we have a little program on user-s PC wrote by our partner. This program tracks incoming calls and for the call rises record in our CRM-System. This program uses tapi3 (it is COM-object from deep inside of windows). Unfortunately, it doesn't work on PC with Windows 10.
Search a lot for causes of this problem didn't give me even some a bit useful answers. And indeed, I am coming to the opinion, that this library by itself have some problems with working with it on Windows 10.
Well I tried a lot of things, before wrote this question. Tried to use other versions (later versions) of tapi driver for cisco (CiscoTSP). Tried to use other instances of tapi3. Tried to make this program work on other machines with win10. And now I have no result.
This small example demos the problem.
using System;
using System.Collections.Generic;
using TAPI3Lib;
namespace TestTAPI
{
class Program
{
static void Main(string[] args)
{
var tapi = new TAPIClass();
tapi.Initialize();
List<String> names = new List<string>();
foreach (dynamic address in (tapi.Addresses as ITCollection))
{
names.Add(address.AddressName);
}
}
}
}
In result of execution I have empty List of Addresses, but it shouldn't be empty.
At least I should be see standard tapi Addresses, but I didn't. Moreover I see in "Control Panel" -> "Telephone and modem", that I have more Addresses then only standards.
Really don't know what is going wrong. Maybe I miss some details?
Or may be I can change using tapi3 to something else to make that work.
Assuming it works on an Win8 or Win8.1 (you did not specify). Have you checked your drivers config? If you save a config setting and then open the config page in "phone and modem" has it reset to default?
TAPI drivers default registry key for storing their config is here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony
Some (not all) flavors/edition/versions of Windows 10 have removed the access rights to the registry key from the built-in system account that runs the telephony service.
I don't know about Cisco specifically, but we have encountered several TAPI drivers from various manufactures that "save" their settings without giving an error, but in fact have not changed because of this issue.
Open your services.msc and check the Telephony (TapiSrv) service account, then check if it has access to the registry key.
I'll try to keep it short. I've been running in Windows 10 (10130) Microsoft's WiFi Direct Services example available on GitHub , the C# one in Visual Studio 2015 RC. Now, in their Build conference they said you can run in CMD a command to know if your WiFi adapter is compatible with WiFi Direct
netsh wlan show wirelesscap
Which gives me a big YES, your wireless adapter is compatible.
Wi-Fi Direct Device : Supported
Wi-Fi Direct GO : Supported
Wi-Fi Direct Client : Supported
But when I run the mentioned sample, everything goes OK until the WiFiDirectServiceWrapper.OnAdvertisementStatusChanged(. . .) is triggered, almost inmediatly after creating the advertiser. While running the sample with the profiler attached I get this:
private void OnAdvertisementStatusChanged(WiFiDrectServiceAdvertiser sender, object args)
--
sender | {Windows.Devices.WiFiDirect.Services.WiFiDirectServiceAdvertiser}
AdvertisementStatus: Aborted
AutoAcceptSession: true
CustomServiceStatusCode: 0
DeferredSessionInfo: null
PreferGroupOwnerMode: true
PreferredConfigurationMethods : _native, can't see_
ServiceError: UnsupportedHardware
ServiceInfo: null
ServiceName: "myservice"
ServiceNamePrefixes: {System.__comObject}
ServiceStatus: Available
I really don't know how I'm supposed to depurate this, as I can't find where this Event is raised (the only references to that method are
this.advertiser.AdversitementStatusChanged += OnAdvertisementStatusChanged
this.advertiser.AdversitementStatusChanged -= OnAdvertisementStatusChanged
^ those), and I can't see the WifiDirectServiceAdvertiser implementation.
My WiFi Card is a Qualcomm Atheros AR9485, and I'm using the latest drivers available through Windows Update. In the device manager I get two Wi-Fi Direct Virtual adapters:
Microsoft Wi-Fi Direct Virtual Adapter
Microsoft Wi-Fi Direct Virtual Adapter #2
The second one is disabled sometimes (the UnsupportedHardware event is the same, enabled or disabled). For all of them I've disabled the "Allow the PC to shut down this device to save energy" option.
I've tried to compile the code to x86 and x64, but I get the same result at the same point. I've tried another two generic wireless thumbs (those USB WiFi adapters) which Windows says yes, they're compatible too with no luck.
I know Windows 10 is not final, but any help is appreciated.
It seems that the WiFiDirect capabilities are not the only ones you need to look at if the thing you want to do is advertise a service (which is actually the "new in Windows 10 thing" concerning Direct).
The command you must execute is exactly the same as before:
netsh wlan show wirelesscap
but if you want to advertise a service, the relevant capabilities are the following:
P2P Device Discovery : Supported
P2P Service Name Discovery : Supported
P2P Service Info Discovery : Supported
P2P Background Discovery : Supported
What WiFiDirect does in Windows since 8 and 8.1 is advertising the whole computer, but since 10, WiFiDirectServices advertises one or more services running simultaneously in your machine.
Lets say you are the developer of com.boardgames. If you want to host a board games competition somewhere without a WiFi hard AP, that could be the prefix of the name of all your services, so each client connects only to the one they want: for example, com.boardgames.solitaire or com.boardgames.chess instead of connecting to your machine.
Sadly, none of the computers nor WiFi antennas I've tried are compatible with P2P discoveries.
Any idea how do I do the following using C#?
Going to Tools -> Internet Options -> Security
Select the Security tab
Click the Custom Level button
In the Miscellaneous section change Display mixed content to Enable
The "cheat" way to do this is to change the value
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\0\1609
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\1\1609
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\2\1609
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\3\1609
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\4\1609
Where 0-4 are Zone identifiers and the value is 0 to Allow, 1 to Prompt, and 3 to Block. Keep in mind that if your code does this on anyone's machine but your own, you're likely to find your code blocked as malware.
The "proper" way to do this is to use the APIs to create an IInternetZoneManager and call SetZoneActionPolicy to adjust the settings for URLACTION_HTML_MIXED_CONTENT in the zones you want to adjust.
You aren't supposed to do this "programmatically". That's why there isn't an API for it. Only the user can change their security settings, and they do it using the built-in interface that you've already discovered.
The poor IE team has been working overtime trying to tighten up the security of their browser. They're not going to throw in something like this that would nullify all of their efforts in a matter of seconds.
Recall that even once this option is selected, there's a confirmation dialog presented. How do you propose to "click" that programmatically? (Hmm, on second thought, don't tell me. That's probably the next question you'll be asking.)
Give up on trying to do this programmatically, and ask the user to do it themselves. Provide a complete help file or other documentation that explains why you're requesting that they make this change, what features will be unavailable if they do not choose to make this change, and what the possible security risks of making such a change are. And, of course, specific instructions on how the change is made.
Or, better yet, redesign your app so that it doesn't require a system-wide modification of IE's security settings. It's hard to imagine a legitimate case for this. A better solution might be asking the user to add your site to their "trusted sites". Remember that local pages have different security settings than remote pages by default.
Also do not forget Group Policies. Most (if not all) IE settings may also be specified in Group Policies.
According to Local group policy setting for IE security page vs Internet options security page
the Group Policy settings override user-defined settings.
So, on my home PC (works without domain controller) I have a choice to define IE settings either via Local Group Policy Editor or via Internet Options. For example, if I run gpedit.msc to open Local Group Policy Editor, select
Computer Configuration\Windows Components\Internet Explorer\Internet Control Panel\Security Page\Internet Zone
change "Display mixed content" setting to "Enabled", then select "Enable" in drop down box, click Apply,
then open Security Settings for Internet Zone in IE - I will see that "Display mixed content" changed to Enable and
the selection is disabled because it is overriden by Policy.

Now back to the question how to change settings programmatically.
EricLaw correctly suggested using SetZoneActionPolicy from IInternetZoneManager.
But it is hard to find samples for calling it from C#.
I ended up copying
http://www.pinvoke.net/default.aspx/Interfaces.IInternetZoneManager
into my code and then doing:
//This will disable "Download signed ActiveX" (IE setting # 0x1001) for Internet Zone (zone #3)
IInternetZoneManager izm = Activator.CreateInstance(Type.GetTypeFromCLSID(new Guid("7b8a2d95-0ac9-11d1-896c-00c04Fb6bfc4"))) as IInternetZoneManager;
IntPtr pPolicy = Marshal.AllocHGlobal(4);
Marshal.Copy(new int[] { 3 }, 0, pPolicy, 1);//3 means "Disable"
int result = izm.SetZoneActionPolicy((uint)UrlZone.Internet, (uint)0x1001, pPolicy, 4, (uint)UrlZoneReg.CurrentUserKey);
Marshal.ReleaseComObject(izm);
Marshal.FreeHGlobal(pPolicy);
I also tried changing group policy programmatically.
I used library from
https://bitbucket.org/MartinEden/local-policy
and then:
//This will disable "Download signed ActiveX controls" computer policy for Internet Zone (zone #3)
const string keyPath = #"SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3";
var gpo = new LocalPolicy.ComputerGroupPolicyObject();
using (var machine = gpo.GetRootRegistryKey(LocalPolicy.GroupPolicySection.Machine))
{
using (var terminalServicesKey = machine.CreateSubKey(keyPath))
{
terminalServicesKey.SetValue("1001", 3, Microsoft.Win32.RegistryValueKind.DWord);
}
}
gpo.Save();
After successfully testing the code above on Win7 SP1 with IE 11 I decided to go back to the original suggestion from EricLaw: modify
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\*\1001
directly because this is what Microsoft is recommending. See, for example How to strengthen the security settings for the Local Machine zone in Internet Explorer or Enhanced Browsing Security
I am not sure but I think you can find all these settings in "registry". You need to find out the appropriate key. And to change those values you need to have proper rights. Registry can be accessed from .net code
I checked out a project from TFS I had worked on a while ago, but when I pressed ctrl+F5 to launch it from Visual Studio, I got this message:
This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.
How do I open this page?
Right click on the project and select Properties. Select the "web" tab and select "Auto assign Port" under Servers. Visual studio will automatically assign a port when it runs for you.
Or if you know a port which is available to use, you can specify that in the "specific port" section.
Try the following:
Type about:config in the firefox address bar.
Search for network.security.ports.banned.override (if this doesn't exist... right click and create it - [new]->[string])
Set the port number to a number you want to use with cassini. You can also use a range of ports (eg 8080-8090)
Once you have done this, you can then set the port to be used in visual studio as Shyju has suggested but instead of setting it to auto-assign port set it to the port you have configured in step 3 above.
It is because the dynamic port of the visual studio is blocked by Firefox. See the solution here
Solution
Taken from the above link
The built in webserver in Visual Studio 2005, formerly known as Casini, uses a dynamic or static port on the localhost machine (e.g. http://localhost:2049/default.aspx).
It is dynamic by default, but you can make it static if you choose. That works very well except when you try it in Firefox. It simply gives you this response:
This address uses a network port which is normally used for purposes other than Web browsing. Firefox has cancelled the request for your protection.
It does that by default whenever you use a port other than port 80 - the default website port. It took me a lot of digging to find the solution and here it is.
- Open Firefox
Type about:config in the address field
Right click anywhere on the screen
Click new > string
Enter preference name as: network.security.ports.banned.override
Enter string value as: 2049 (or whatever port number you want)
Change the port? (right click the project and properties (or alt + enter) and Specify port
