The reason being that the select box has been styled (it uses a background url to give it a custom appearance). If I remove this class attribute I can simple use <code>size="10"</code> in the html tag, or change it dynamically with:</p>
<pre><code>var o_select = document.getElementById("mySelect");

When the user click the items on the Dialog, the background will be changed.</p>
<p>I have tried two ways of implementing this function above:</p>
<p>1) use the Android:theme in AndroidManifest.XML. This really worked. But the bad thing was that all the View in the application will extend the theme. I made the background of unrelated views null. But i can not remove extended theme in the Dialog. This made my dialog very ugly. </p>
<p>2) I applied 'style' in the layout xml of the three activity. But the problem is that i can not modify the background attribute in the style programmatically. </p>

WiFi tags are placed on the wall and android is carried by blind student. The student's time table, shortest path algorithm to reach specific lecture hall is loaded onto HOST.</p>
<p>Whenever android mobiles comes in vicinity of any Wifi tag, it receives the beacons from WiFi Tag. In order to achieve this, android has to scan all the wifi devices every 3 sec(say).So, the android has to forward the WiFi tag id (mac address), android mac id, Received Signal Strength to the HOST. So, how should I do this? What are the different applications to be loaded onto the android mobile? How should the scanning be done?</p>
<p>Once HOST receives the data from android, it will determine the shortest path in accordance to algorithm and has to send back instruction (say direction - Go Left) to android. So, how can we do this? Since the student is visually impaired, the incoming msg should be audio.</p>

3,727,680 | 3,727,681 | Distributing a development version of an iPhone application | <p>My company has recently started developing custom iPhone applications for various clients. One of the challenges we are running into is how to get these applications to the client so they can review them during the development process.</p>
<p>Ideally, this would just be a matter of sending them the app file and having them install it on their iPhone. Of course app signing makes things much more complicated than that. We would have to add their phone ID to our development profile, have them provision their phone to accept the app, then install the app. This creates a headache for us of course in trying to walk the client through this process.</p>
<p>At this point, our best solution is either to simply send them screenshots or to snail-mail an iPod Touch back and forth with the app installed on it. Of course neither of those options is ideal.</p>

4,155,930 | 4,155,931 | jQuery partial form reset to initial value | <p>I have a form that has a bunch of input type="text" boxes that are loaded with values from a database. I can then change these values and POST. This form has a few subsections that I have boxed in with framesets. What I would like to do is give the user a button to undo any changes they have made to inputs in a particular fameset. I know I can use:</p>
<pre><code>$('#myForm').get(0).reset();
</code></pre>
<p>To reset the entire form. I was hoping that I could do something like:</p>
<pre><code>$('#myForm #myFrameset').get(0).reset();
</code></pre>
<p>or</p>
<pre><code>$('#myForm input').get(0).reset();
</code></pre>
<p>to reset the input boxes within a particular frameset. However, (valuable lesson of the day for this noob) .reset() is only a form selector so when I ('#myForm #myFrameset') I am selecting an element and not a form. </p>
<p>I don't want to reload from the database because it seems to me that the data I want is there. I just can't figure out how to access it without resetting the entire form. I'm going to work on a function where I store the value in the input placeholder and set the input value to the placeholder value on reset button click. It should work but I'm wondering is there a simpler way to do this in jQuery? Is there a better way to do this in general?</p>
