Thanks for this example, you helped me to finish easily a task.
I needed to get a session variable. I followed your example.

Amazing,

Erika.

this :

Silverlight1.InitParameters = “IpAddress=” + HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

Doesn’t work for me. The intellisence doesn’t see “Silverlight1″

So how is the System.Collections.Generic.KeyNotFoundException solved?

Yes. you are right. It is not like ActiveX made by VB or etc. It’s the limited version of ActiveX. but Silverlight did support Socket but it has some limitations.

Hi,

sorry to bother you. I wrote a few asp.net with ajax/js, js does not achieve something because it simply does not support. if for security reason, I could understand, but since SL 2 include the System.Net namespace, it should work. but I also read some articles of yours, tim heuer and other SL guys, mentioned about some mechanism that work with browser such as WebClient not using socket but the browser’s plug-in functions, I might understand, though.

after all, could we conclude that SL is NOT simply a client “object”, but a “limited proxy” between server and client? it could not fully runs as other activexs that run at browser, and could not do those things like activex made by vb6 that could utilize winsock etc?

no.. Silverlight is not windows application. It runs on the browser but it runs within sandbox. so, it has some limitations.. if you are familiar with web client-scripting technology such as Javascript or VBScript, you will understand those limitations…

Hi,

I don’t get it. for a winform/c++/vb/delphi program, they can all get the client ip through winsock which System.Net.Dns internally wraps. since the SL runs at client machine, why?

I think System.Net.Dns doesn’t give me the correct IP. Yes. Silverlight runs at client-side that’s why I think we can’t get the IP Address. Like Javascript, we are not able to get the client ip address from Javascript.

Hi,
since SL 2 introduced System.Net namespace, why not just use System.Net.Dns functions to get the client ip? the SL runs at client side, right?
