3,611,991 | 3,611,992 | Disable keypad or whole keyboard support on android activity? | <p>I have a layout with lots of different imagebuttons on it.<br>
Application is developed in full-touch, so there should be no response to keyboard or keypad on all activities except one, where user can input his name.<br>
Is there a way to achieve that? </p>
<p>I've checked on debug, keypress and keypad press result in onKeyDown event.<br>
I've set it to return 'false' for all keys.<br>
But, for some reason, android keeps selecting my imagebuttons when keypad is pressed.<br>
And pressing Enter key result in View.onClick event.</p>
<p>How to totally disable all keyboard input for activity?<br>
I use Motorola Milestone for tests - a slider with a keyboard<br>
Thanks</p>

Since these lists will have as many as almost 400 billion numbers before processing we need to split them up but I haven't the slightest idea (since I can't find an example) of where to start when trying to process a list from a specific point in Python. Edit: Right now we are <em>not trying to create multiple-dimensions</em> but if it's easier then I'll for sure do it.</p>

<p>the flow i had so far was :</p>
<pre><code>TcpClient tcpClient = new TcpClient(serverName, port);
SslStream sslStream = new SslStream(tcpClient.GetStream(), false, null, null, EncryptionPolicy.RequireEncryption);
sslStream.AuthenticateAsClient(HostName);
</code></pre>
<p>i keep on crash in the "AuthenticateAsClient".
the reason is that one AS is working only with the mentioned cipher.</p>
<p>i have verified this is the case with the <a href="http://code.google.com/p/sslscan-win/" rel="nofollow">SslScan tool</a>.</p>
<p>i have tried to enter this cipher through the policy editor (gpedit.msc in the command line)
but again with no luck.</p>
<p>basically i'm looking for a way to use this cipher from code dynamically.</p>
<p>i have a working Java code
`</p>
<pre><code>sslsocket.setNeedClientAuth(true);
String[] list = new String[1];
list[0] = "ADH-RC4-MD5";
sslsocket.setEnabledCipherSuites(list);
</code></pre>

3,264,812 | 3,264,813 | "download" of client-side data from JS (without a new server round-trip) | <p>I've got a bunch of data on the client side, in JS. I want to allow the user to save that data to the local hard drive in text (CSV actually) format.</p>
<p>I can easily accomplish this by posting all of this data up to the server using ajax, then initiate a GET from the client to download the data. But that seems wasteful. Especially if the data is large.</p>
<p>The client already has the data -- I could certainly show it to them, and allow them to copy/paste it into their favorite text editor -- but that's not a very nice UI.</p>
<p>I want to allow them to save the data to a local file. I understand the security implications here.</p>

I have 3 years of programming experience but am stumped on some of the simplest problems in the class, lol. New to Java, not new to programming rather. I would like to discuss why the questions result in an answer and why it is one way or another.</p>
<p>1) Write 3.4, is this a double or a float?</p>
<p>I want to say its a float by default, as it takes up less space (32 bits) versus a double (64) bits. Since 3.4 is a small number, I would assume it is a float?</p>
<p>2) Declare x as a double and assign it the value of 3.4 (as a double).</p>
<p>I think it is <code>double x = 3.4d;</code> not 100% sure on this</p>
<p>3) Declare y as a float and assign it the value 3.4 (as a float).</p>
<p>Similar to above, i think it is <code>float y = 3.4f;</code></p>
<p>Not usually one to come on here and ask for HW help in this manner...but I have no textbook for another week as I just ordered it. I would rather like to discuss why it is one way or another so I can get a better understanding of how Java works. Thanks.</p>

379,620 | 379,621 | Resume Activity with back button | <p>I have an application I am creating with a DashboardActivity & a SettingsActivity. On the dashboard, I have one object displayed, but when I go into settings, I want to be able to select/deselect X options. Once the user clicks the back button, I save that data locally and to the server. Once the phone receives a success message from the server that it was stored properly, I want to reload the dashboard. </p>
<p>I thought I would do this with the onPause and onResume, but they are called when the DashboardActivity is first created. What would be the best way to reload the dashboard by calling my web service after the settings were saved to the server? Here is what I am doing when the back button is hit</p>
<pre><code>@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
//Save data to the server once the user hits the back button
if ((keyCode == KeyEvent.KEYCODE_BACK)) {
SchoolSearchActivity.this.divisionProxy = new DivisionProxy(SchoolSearchActivity.this.saveUserDivisionHandler);
SchoolSearchActivity.this.divisionProxy.submitUserDivisions(SchoolSearchActivity.this.userDivisions, SchoolSearchActivity.this.user_id);
//SchoolSearchActivity.this.finish();
//Toast.makeText(SchoolSearchActivity.this, "Divisions Saved",Toast.LENGTH_LONG).show();
}
return true;
}
</code></pre>
<p>The above opens an HTTP connection, and when the response is received, the handler processes the response. I want to:
1) submit the data to the server
2) return to the previous activity
3) show a progress dialog until the response from #1 returns (response handler is in the settings activity; and we are now in the dashboard activity)
4) "refresh" the dashboard</p>
<p>What is the best way to accomplish this so I can just resume the dashboard as it was. Like I said, when I overwrite the onResume method, it is called when the activity is first created. I was considering putting my webservice call in onResume, so it's called once everytime you make it to the Activity, but it doesn't seem like the cleanest way.</p>

<p>Why is it good practice to use if (myBoolean === true) in JavaScript? As a relatively inexperienced JavaScript user, I'm trying to work out in what specific, real-world scenarios you'd end up with a value that might be a Boolean true or might be a "truthy" value, so that you would need to check if (myBoolean === true) rather than if (myBoolean)</p>

27,123 | 27,124 | Need to post JSONObject to PHP server through parameter | <p>From past couple of hour I was trying to send JSONObject to a PHP server. I need to send this object through a parameter.</p>
<p>Some what like this:</p>
<pre><code>message={"name":"Firstname","email":"[email protected]"}
</code></pre>
<p>here message is my parameter name.</p>
<p>Yes I am using HttpClient for posting my request. As I have mentioned that I need to send a post request to the server attaching a JSONObject to a parameter, I am using the following methods:</p>
<p>Supose my exact URL is like <a href="http://www.example.com/" rel="nofollow">http://www.example.com/</a> then I need to append deviceID, date and message type with the URl so as to make it look like <a href="http://www.example.com/deviceID/date/140" rel="nofollow">http://www.example.com/deviceID/date/140</a> then to this URL I need to send a post request which is a JSONObject attaching it to a parameter named message.</p>
<p>For this I am doing:</p>
<pre><code>String url = "http ://www.example.com/deviceID/date/140";
JSONObject j = new JSONObject();
j.put("name", "Firstname");
j.put("email", "[email protected]");
HttpClient httpclient = new DefaultHttpClient();
HttpPost request = new HttpPost(url);
BasicHttpParams params = new BasicHttpParams();
params.setParameter("message",j.toString());
request.setParams(params);
HttpResponse response = httpclient.execute(request);
</code></pre>
<p>If I pass this way, the server returns a JSONObject error message saying <code>"error":"name not found"</code> -- what am I doing wrong?</p>

1,782,320 | 1,782,321 | jQuery percentage width has up tick when animating down. | <p>Does anyone know why jQuery has an uptick in the width percentage when using animate to scale down the width of an image. This only seems to happen when you are scaling down a div with a percentage based width that is within a div that is also using a percentage based width. See <a href="http://jsfiddle.net/buz9L/" rel="nofollow">this</a> example in it you can see that the square to the right drops down for a split second in the up tick. If you try ordering the animate changes on completion handlers there are similar results due to the uptick. The example is based on <a href="http://stackoverflow.com/questions/8299608/jquery-animate-with-percenteges">this</a> other SO issue but is unanswered for my use case. I'm guessing it has something to do with 3rds and floats in ranging limits with percentages in jQuery, but maybe there is a simple solution out there. Thanks in advance for any help. </p>
