Windows.Web.UI.Interop.WebViewControl localhost access

Jul 25, 5:34

If you're developing with the new Windows.Web.UI.Interop.WebViewControl you may have noticed you cannot navigate to localhost HTTP servers. This is because the WebViewControl's WebView process is a UWP process. All UWP processes by default cannot use the loopback adapter as a security precaution. For development purposes you can allow localhost access using the checknetisolation command line tool on the WebViewControl's package just as you can for any other UWP app. The command should be the following:

checknetisolation loopbackexempt -a -n=Microsoft.Win32WebViewHost_cw5n1h2txyewy

As a warning checknetisolation is not good on errors. If you attempt to add a package but get its package family name wrong, checknetisolation just says OK:

C:\Users\davris>checknetisolation LoopbackExempt -a -n=Microsoft.BingWeather_4.21.2492.0_x86__8wekyb3d8bbwe
OK.
And if you then list the result of the add with the bad name you'll see the following:
[1] -----------------------------------------------------------------
Name: AppContainer NOT FOUND
SID: S-1-15-...

There's also a UI tool for modifying loopback exemption for packages available on GitHub and also one available with Fiddler.

As an additional note, I mentioned above you can try this for development. Do not do this in shipping products as this turns off the security protection for any consumer of the WebViewControl.

“Both men bought tickets that gave them unlimited first-class travel for life on American Airlines. “

“He was airborne almost every other day. If a friend mentioned a new exhibit at the Louvre, Rothstein thought nothing of jetting from his Chicago home to San Francisco to pick her up and then fly to Paris together.”

“She pulled years of flight records for Rothstein and Vroom and calculated that each was costing American more than $1 million a year.”

MPAA Boss: If The Chinese Censor The Internet, Why Can't The US? (techdirt.com)

2011 Dec 10, 8:31

FTA:

The MPAA is getting pretty desperate, it seems. MPAA boss Chris Dodd was out trying to defend censoring the internet this week by using China as an example of why censorship isn’t a problem. It’s kind of shocking, really.

“When the Chinese told Google that they had to block sites or they couldn’t do [business] in their country, they managed to figure out how to block sites.”

Comcast Digital Switch Impact on My Windows Media Center

2009 Sep 25, 2:19

Amateur wireless station (LOC)Irritatingly out of line with what their commercials say, in my area Comcast, under the covers of the national broadcast digital switch, is sneaking in their own switch to digital, moving channels above 30 to their own digital format. Previously, I had Windows 7 Media Center running on a PC with a Hauppauge PVR500 which can decode two television signals at once setup to record shows I like. The XBox 360 works great as a Media Center client letting me easily watch the recorded shows over my home network on my normal TV.

Unfortunately with Comcast's change, now one needs a cable box or a Comcast digital to analog converter in order to view their signal, but Comcast is offering up to two free converters for those who'd like them. The second of my two free converters I hooked up to the Media Center PC and I got the IR Blaster that came with my Hauppauge out of the garage. I plugged in the USB IR Blaster to my PC, connected one of the IR transmitters to the 1st port on the IR Blaster, and sat the IR transmitter next to the converter's IR receiver. I went through the Media Center TV setup again and happily it was able to figure out how to correctly change the channel on the converter. So I can record now, however:

  1. I can only record one thing at a time now
  2. Changing the channel is slow taking many seconds (no flipping through channels for me)
  3. The Hauppauge card can't know if the channel change worked. So if it tries to change to HBO (I get it for free with one of the Comcast packages) which is encrypted and the converted won't show, the channel doesn't change but the PC doesn't know it and ends up recording some other channel.
To fix (3) I need to manually go through and remove channels I don't have from the Media Center. To fix (1) I may be able to get a second IR transmitter, a third digital converter, hook it up to one of the other inputs on my Hauppauge, and go back through the Media Center TV setup. There's no fix for (2) but that's not so bad. All in all, its just generally frustrating that they're breaking my setup with no obvious benefit.PermalinkCommentsdigital tv hauppauge mce cable windows media center comcast
