Given a stream of bytes, you have to know what encoding it is to begin with - email use mime headers to specify the encoding, http uses http headers to specify the encoding. Also, you can specify the encoding in a meta tag in a web page, but it is not always honored.

It can refer to any code executed by a virtual machine rather than directly by the CPU.

_In a controlled environment,_ using SmtpClient would be the answer. But on a user's machine you would need an SMTP server to send through.

When to use HtmlControls vs WebControls |
|asp.net| |
I like HtmlControls because there is no HTML magic going on... the asp source looks similar to what the client sees.
I can't argue with the utility of GridView, Repeater, CheckBoxLists, etc, so I use them when I need that functionality.
Also, it looks weird to have code that mixes and matches:

Assuming 32 bit ints:
bool same = ((x ^ y) & >> 31) != 1;
Slightly more terse:
bool same = !((x ^ y) & >> 31);

Thinking back to my university days, in most machine representations, isn't the left-most bit of a integer a 1 when the number is negative, and 0 when it's positive?
I imagine this is rather machine-dependent, though. |
You don't mention which version of .NET you're using, but something that's worked for me in using Visual Studio .NET 2003 is to provide a thin C# wrapper around the pimpled implementation of the real C++ class:

(integer1 * integer2) > 0
Because when two integers share a sign, the result of multiplication will always be positive.
You can also make it >= 0 if you want to treat 0 as being the same sign no matter what. |
wget is probably the most complete method. If you don't have access to that, and you have a template based layout, you may want to look into using Savant 3. I recommend Savant 3 highly over other template systems like Smarty.

You need to set AutoPostBack to true (so that the \_\_doPostBack javascript function will get rendered in the page output) and then manually override the onchange attribute with a confirm() and a manual call to __doPostBack:

In my experience, there's very little difference. As Darren said, if you don't need server-side functionality, HTML controls are probably lower-impact.
