I am working to create a wifi connectivity for a windows ce 7 device using connection manager. I am new to wince. Can anyone suggest how to establish a connection with a network. I actually wanted to have a list of available networks and to select a network from that. Please help me out in this situation. Awaiting your valuable responses. Thank you.
You mean listing all the available wi-fi networks and then connecting to one of them?
Do you need to have a UI for this (to enter the wlan password etc.) or you'll provide your own UI and just need low-level function to activate the connection?

I want to create a tunnel between my computer (which is connected to the router via ethernet and runs on windows) and another computer in the same subnet.
I chose WINTUN.dll for this purpose because it is much faster and more efficient than OpenVPN.
I can't find a way to start a season on the ethernet adapter on my laptop!
I tried using the adapter name found on MS INFO:
WINTUN_ADAPTER_HANDLE Adapter = WintunOpenAdapter(L"Realtek USB GbE Family Controller");'
Result: "error creating adapter, code: 1168"
I searched the library documentation and could not find anything on the subject.
Will Wintun work under any circumstances with non-Wintun adapters?
Any help will be appreciated! thank you!
You cant open your Realtek USB (...) Ethernet Adapter. Wintun is used to create a Layer 3 Network Adapter. You need to initialize wintun and afterwards create an Adapter. If there isnt one in your adapter settings, you cant open one. Id encourage you to implement the example.c from wintun.net. This way you will get the hang of it. If you want to use wintun for your scenario you will need to implement it by yourself. OpenVPN might be slow because it uses a TAP Adapter (wild guess) but you can change it to a tun adapter (e.g wintun). Hope that helps :)
I am playing around with an application to do some remote connection and I am struggling with understanding the tun/tap. I have installed OpenVPN tuntap driver and can connect/configure it through my application but I need some clarification.
If I use it in TAP mode I need to bridge my network adapters correct??
How would a TUN interface be setup?? I know that I need to call DeviceIoControl with TAP_IOCTL_CONFIG_TUN and I think I understand how but my research leads me to think I also need to add into the windows routing tables??
Can someone layout what a typical TUN Layer3 VPN would look like
Thanks

Sorry for asking such a mundane question, but I'm suddenly curious. If I open the network connections dialog on my Windows machine, it shows me a cute little picture of my computer connecting to a router and then to a globe (labeled Internet). What is Windows trying to connect to in order for it to decide that the computer has Internet connectivity? I assume there is no IP4 address for 'The Internet', so where is it going? Is it just sending a ping to an address back at the Microsoft home office? If that address were to disappear, would my window's machine suddenly decide that it no longer has a route to the Internet? Would Windows boxes that were 'close' to that address incorrectly report that they could get to the Internet when they couldn't.
I'll stop now before this gets too silly. But seriously, what criteria does a Windows box use to determine that it has Internet connectivity? I'm assuming that Linux and iOS systems have an equivalent feature. Do they use the same criteria?
The general IP address that is used for 'the internet' is 8.8.8.8 - or Google.com.
If you can ping it, and get a web page from it, then there's a pretty good chance you can get to at least some of the internet.
But for specifically Windows - Network Connectivity Status Indicator - it uses a different domain: dns.msftncsi.com
It will (unless disabled by GPO):
resolve the name, and verify it has the 'right' IP (131.107.255.255
fd3e:4f5a:5b81::1 )
Perform a HTTP get to this address and check it gets a result. NCSI
Presumably if different responses are retrieved, then it can tell if it has a wi-fi login or similar.
Your intuitions seem correct. I am not on a Windows machine but you could find out by firing netstat and then connecting.
If I was programming this I'd make Ping, TCP and HTTP requests. Some devices are connected through proxies such as firewalls, captive portals and others. the only way to be sure is to send something and receive a reply.
My Android device for example can detect captive portals. It probably does that by trying to HTTP connect somewhere.
I am trying to connect two windows phone emulators without router to form p2p network, is there any solution to connect them with access point without router and internet. and can be a possibility of using IP address of emulator.
answer plz
To the best of my knowledge no it is not possible in Mango - but is in WP8. You could however use a wireless network to perform create a UDP multicast socket and and then "connect" to one another that way.
Have a look at http://blogs.msdn.com/b/davrous/archive/2010/03/29/windows-phone-7-platformer-starter-kit-for-xna-studio-4-0.aspx it's got some pretty good pointers.
I want to open an IPsec tunnel from the Windows XP PC (I can do it using MMC GUI) and get callbacks(some Windows API) on the connection status in my application(it can be C, C++ or any other application) like CONNECTION_ESATBLISHED, CONNECTION_FAILED or NEGOTIATION_FAILED.
In other words, I want to know if the tunnel was established, if it's running properly or had being closed through my application code.
I've googled a lot on the subject, but couldn't find any useful information...
Anyone has any ideas?
Thanks a lot!
If you want to create a VPN connection (IPSec) you can configure it with the Remote Access Client API. Create a Ras Entry with RasSetEntryProperties with your IPSec configuration and dial with RasDial. A callback function will notify you about the connection state.
