1,947,497 | 1,947,498 | ASP.NET Webmail Engine | <p>A friend of mine asked me today if there is any open-source or commercially available Webmail/Email "engine". When I asked her what she meant by engine, I got a list of features her boss asked for - </p>
<ul>
<li>Web interface to login & access e-mails</li>
<li>Ability to send/receive/forward e-mails using the web interface </li>
<li>Ability to compose and save drafts using the web interface</li>
<li>Ability to delete emails, empty deleted items folder using the web interface</li>
<li>Ability to search e-mails (by Sender's e-mail, Subject, Content)</li>
<li>Maintain and manage a contacts list (of e-mail addresses) using the web interface</li>
<li>Allow users to synchronise their e-mails with iPhone/Windows Mobile smartphones</li>
</ul>
<p>I found <a href="http://anmar.eu.org/projects/sharpwebmail/" rel="nofollow">SharpWebMail</a> to have some of the features, although it has not had updates in recent times, last update was in April 2006. I am inclined towards using ASP.NET, the proposal is to primarily use the e-mail in conjunction with an intranet (developed in ASP.NET). If you have any suggestions, please let me know.</p>

<p>in the main activity i have a button when I click on this button I go to the Test activity</p>
<p>in the Test activity I want the application to automatically append some text to the textview that it has every 10 seconds</p>
<p>this text can be for example "test"
so every 10 seconds "test" will be added
but, when I leave the activity and go to the main activity, this process will continue happening
so if for example I spend 20 seconds on the main activity and then return to the Test activity, I will see two more "test" strings in the textview..</p>
<p>I tried doing this with timertask and had no success at all</p>
<p>this is the Test activity's code, in the main activity I just have the button that shows me the other activity</p>

1,552,998 | 1,552,999 | how to separate several "a little bit connected" projects? | <p>The main class in my program is <code>OrderBook</code> of some stock.</p>
<ul>
<li>one part of my program, let's call it, <code>NYSE Connector</code> reads data from <code>NYSE</code> and constructs <code>OrderBook</code> of some stocks</li>
<li>second part of my program, let's call it <code>LSE Connector</code> also constructs <code>OrderBook</code> of other stocks but from different exchange and by completely different algorithm</li>
<li>third part of my program manages all set of <code>OrderBook</code> and produce different signals to different connectors (buy such stock on LSE sell another on NYSE etc.)</li>
</ul>
<p>All parts of my program share the same instances of <code>OrderBook</code>. But parts itself are pretty independent. For example I can just run <code>NYSE Connector</code> without running anything else. Then I will just collect <code>OrderBook</code>. Doesn't make much sense, but possible.</p>
<p>Also I need everything to work asap, because even 1 ms is very important for me.</p>
<p>So now I just placed everything in one project (but in different folders), but I think it is not very good. If I will need another connector - I will just create one another folder.</p>
<p>How can I better separate my parts? But remember I need to share the same <code>OrderBook</code> instances.</p>

3,220,441 | 3,220,442 | Asp.net Cookie Domain / Scope | <p>I have a "cookie" handler / utility class that works quite well for me. It abstracts away a lot of the issues that I drive me crazy when dealing with cookies such as how to handle a response (write) operation followed by a request (read) operation on the same postback, how to handle encryption, etc.</p>
<p>The one thing that eludes me is how to segregate my cookies across different “virtual” domains. My applications are running in an intranet environment all with the same host / server name:</p>
<p><a href="http://server/app1/" rel="nofollow">http://server/app1/</a></p>
<p><a href="http://server/app2/" rel="nofollow">http://server/app2/</a></p>
<p>I don’t want these different applications sharing cookie values in the event that they use the same names. Approaches on the Request / Response object?</p>

So as now I has to switch back to <code>onSaveInstanceState</code> I want to as what is the proper way to handle a huge amount of data distributed by tens of objects?

1,024,842 | 1,024,843 | Javascript Show Hide - Changing toggle action from Checkbox to <a href> links | <p>currently I have a method of showing / hiding a div based on a form checkbox field as per below. What I do want however is to not use a form to show hide rather just call the show / hide function based on a simple on a link . I hope this makes sense what I am attempting to do. Any help /advice would be really valued!</p>
<pre><code><!-- Show hide-->
<script language="JavaScript">
function showhidefield()
{
if (document.goform.areas.checked)
{
document.getElementById("areaone").style.display = "block";
document.getElementById("areatwo").style.display = "none";
}
else
{
document.getElementById("areaone").style.display = "none";
document.getElementById("areatwo").style.display = "block";
}
}
</script>
<form name="goform" id="goform" action="xxxx" method="post" enctype="multipart/form-data">
<label><input name="areas" type="checkbox" onclick="showhidefield()" value="1"> Yes </label>

<div id="areaone" style="display:none;">
Area One
</div><!-- / Hideable area -->
<div id="areatwo" style="display:block;">
Area two

<p>Changing the above so that rather than using a form checkbox to showhide, have a toggle effect based on event e.g.</p>

<a href="xxx">Show Areatwo / Hide Areaone</a>

1,563,615 | 1,563,616 | Tarring files together as iterable in Python? | <p>I'm running a WSGI server and part of the API I'm writing returns some (rather large) files along with meta-data about them. I'd like to tar/gzip the files together both to conserve bandwidth and so only one file has to be downloaded. Since WSGI lets you return an iterable object, I'd like to return an iterable that returns chunks of the tar.gz file as it's produced. </p>
<p>My question is what's a good way to tar/gzip files together in Python in a way that's amenable to streaming the output back to the user?</p>
<p>EDIT:</p>
<p>To elaborate on my response to Oben Sonne below, I'll have a function such as:</p>
<pre><code>def iter_file(f,chunk=32768): return iter(lambda: f.read(chunk), '')
</code></pre>
<p>Which will let me specify a chunk size to return from the file when returning it to the WSGI server.</p>
<p>Then it's a simple matter of:</p>
<pre><code>return iter_file(subprocess.Popen(["tar", "-Ocz"] + files, stdout=subprocess.PIPE).stdout)
</code></pre>
<p>or, if I want to return a file: </p>
<pre><code>return iter_file(open(filename, "rb"))
