Detect network connectivity from a WPF/XBAP Application?

Wednesday, May 13, 2009 by Nate Bross

Someone asked on Stack Overflow:

Is there any way to determine if an XBAP (WPF hosted in a browser) application has network connectivity? If not, how would a traditional windows client written in C# and .NET determine if it has connectivity?

Basically the use case is an XBAP application running on a mobile laptop connected to an intranet via WiFi. The laptop will not have a connection to the Internet. The WiFi connection may or may not be there depending upon where the user is at the time.

GateWayIPAddressInformation should work: http://msdn.microsoft.com/en-us/library/system.net.networkinformation.gatewayipaddressinformation(loband).aspx

If you get the gateway IP address, and you can Ping (http://msdn.microsoft.com/en-us/library/system.net.networkinformation.ping(loband).aspx) it you are probably connected.

IIS Server Name Change

Tuesday, May 12, 2009 by Nate Bross

Someone asked on Stack Overflow:

I have a certificate for that is valid for *.MyCompany.com. That is fine for my dev and test servers because the first part of the URLs for those computers ends like that.

I want to test this on my computer and the certificate is incorrect because my computer defaults to the url MyComputer.MyCompany.net.

Is there a way to fake out IIS in to thinking that my computer is .MyCompany.com or am I out of luck when it comes to testing this?

Thanks, Vaccano

You should be able to edit the host header values for the IIS website to accept *.Mycompany.com. To get the DNS to resolve and work correctly, you may need to add an entry to your windows hosts file — mycomputer.mycompany.com 127.0.0.1. that will let you test locally.

Another option would be to use a self-signed cert for local development.

Is Adobe AIR a good engine as GUI to develop Windows application

Thursday, May 7, 2009 by Nate Bross

Someone asked on Stack Overflow:

I want to develop a photo browser application in Windows platfrom, the UI should be very cool and has 3D effects,Adobe AIR is a good engine as GUI, but I don’t know how to integrate my C and C++ engines which I worte before into Adobe AIR, it seems the engine can’t hold ActiveX? What can I do? Thanks.

I posted the following answer, which was chosen as the accepted answer and received 4 upvotes:

If you are windows only, something like WPF is probably a better option, since you will be able to leverge any old C/C++ libraries you have throuhg PInvoke.

Air is best suited to using data with web services.
