Is there a way to get a notification when a new Wifi Network has been detected?
I glanced through the Native Wifi API Reference and found the WlanRegisterNotification function but I'm not sure if that includes what i am looking for. The remark does not mention it.
Yes, WlanRegisterNotification is indeed the correct function. You need to do a little digging in the documentation to find exactly what each notification provides, by looking at WLAN_NOTIFICATION_DATA (in the remarks section for WlanRegisterNotification), then WLAN_NOTIFICATION_ACM†. Specifically, you're looking for one of these two notifications:
wlan_notification_acm_network_available Which gives a notification when a connectable network is detected, and you're not currently connected to another network, and there isn't an automatic connection available.
wlan_notification_acm_scan_list_refresh (Windows 8+)
† ACM stands for "auto configuration module"

IP phones like NRP1000 or NRP1002 have a browser-based setting interface by which you can change all the phone settings. I was looking for some API or so, to do the same operation programmatically, but I could not find any document on this.
A hard way I think is to emulate all the http/TCP communications.
Any simpler suggestion?
Most VoIP phones support (auto)provisioning, usually few different methods of fetching configuration - pre-configured address, address based on manufacturer server, address from DHCP server, SIP multicast with ua-profile. Provisioning can be time-based (e.g. daily) and/or at phone reboot (which may be forced with SIP NOTIFY).
Refer to manufacturer documentation, perhaps contact manufacturer directly (I never heard of this brand but datasheet claims it supports provisioning). If something is missing look also at Fanvil documentation as first of these phones look definitively like one of Fanvil models.
I spend lot of time searching how to determine the current network type such as WIFI, 3G, Ethernet.
But I cannot find any information online in windows platform.
I want to detect the Ethernet network type, but I cannot find any API that can retrieve the network type.
I've find Connection Manager for keyword but there's less information.
Did anyone have any idea?
Please help me...I was blocked by this for 2 weeks.
Thanks.
Look in the registry key HKLM\system\state\connections, there is are entries for each of the possible network types, for instance:
When connected to a wireless network:
[HKLM\system\state\Connections\Network]
Adapters="BCMSDDHD1"
Count=dword:00000001
Descriptions="Business World"
when connected to activesync:
[HKLM\system\state\Connections\Desktop]
Adapters=""
Count=dword:00000001
Descriptions="CurrentDTPTNetwork"
The Count value under HKLM\system\state\connections gives you the total number of active connections.
In HKLM\system\state\Hardware you can find the current power state of the various devices.
There is an API on Windows Mobile that makes it easier to access these values vs. going directly to the registry. See the SystemState class documentation, specifically the ConnectionsNetworkCount and ConnectionsCount properties.
I need to search for available wireless networks and take this list and store it. I tried searching in MSDN Library for information, plus Google. But no luck.
Kindly help me. Thanks.
The best you can do regarding the wireless connection is determining the connection type. There is no way to access or manipulate details about the connection.
See this MSDN article for more information on using NetworkInterface.NetworkInterfaceType to determine the connection type
Windows Phone (even Mango) does not have an API that exposes this information.
So I have a bluetooth device, this device uses SPP to transfer data between the PC and itself. It connects fine through Windows as a bluetooth device. I can find it, enter the paring code and assign it to a COM port. Now I want to be able to send data through the com port using Windows API but it is refusing to do so.
I suspect that I need to setup the COMMCONFIG Structure correctly (see below)
http://msdn.microsoft.com/en-us/library/aa363188(VS.85).aspx
Unfortunately I have no idea what is the proper setting. I know SPP is supposed to emulate the RS-232 communication... so maybe I have to study up on that to figure out the right setting? Or is there some automatic way to set the COMMCONFIG structure.
I seriously doubt it. If it would be used then you'll have no chance at guessing at the custom provider data without docs from the driver author. Pay attention to the handshake signals, serial port devices routinely ignore anything sent to them when the DTR signal is turned off. And not send anything back with DTR off. A driver would emulate that. Use EscapeCommFunction() to turn them on. Also try a serial comm program like HyperTerminal or Putty to test this so you can isolate the source of the problem.
Why not use the Bluetooth sockets API? No need for troublesome (virtual) COM ports then.
If you're using managed code then see my library 32feet.NET
If using native code, use SOCKADDR_BTH with Winsock connect etc, see e.g. Bluetooth and connect (Windows) Then you can use the standard Winsock send/recv API
Ok, I found that you can use the
GetCommConfig and GetCommState functions to figure out the settings.
I could do an endless timer checking IsInetOffline(), but I would prefer a hook callback that tells me when I plug/unplug the ethernet network cable or connect to wireless internet. Is there such a thing in the Windows API?
If you're on .NET you can use the System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged event. It's using Winsock APIs under the covers if you need to do it without .NET (Reflector it if you want to know more), but it's some nasty async stuff in there- not a nice handy "call me when the network status changes".
There may be a better way, but there is a NotifyAddrChange asynchronous function in the IP Helper Library that will create a notification when an IPv4 address changes.
It's done with Win32 Shell Notifications (Explorer does that)
You can see here for code in C.
