Displaying dynamic data on a form
|
<p>I have created a form that contains various Jtextfields to display data. The data comes from an internet source and changes very frequently (every few seconds). I'm not sure the best way about doing it.</p>
<p>So far I have a class that retrieves the data upon request and stores the data locally. The data then can be retrieved using the getters and a timer.</p>
<p>eg.</p>
<pre><code> class Grabber(){
static String data;
static void update(String source){
//update data from source
}
static String getData(){
return data;
}
}
</code></pre>
<p>Then in the form file, MyForm.java I have:</p>
<pre><code> Timer timer = new Timer(2000, performUpdate);
timer.start();
....
ActionListener performUpdate = new ActionListener(){
public void actionPerformed(ActionEvent evt){
Grabber.update();
jTextField1.setText(Grabber.getData());
}
};
</code></pre>
<p>I believe this would work, but I'm not sure if this is the best way to do it and I just want to check I'm not doing something stupid. I thought about having the timer inside the Grabber function, and then calling a function inside MyForm <code>updateData(String data)</code> I think this would be nicer, but then it adds a dependency on the GUI which doesn't seem right.</p>
<p>Another issue is that I intend to have a few sources. Performing the updates in my proposed manner would require serial internet requests which may be better done in parallel? I would like the data to be as up to date as possible. </p>
<p>Apologies if this is not a typical question, but I'm just looking for other ideas on how to implement this.</p>

How to display an image when pressing a button in html?
|
<p>I thought doing something like this would have worked, but I'm confused as to why it isn't when the style is hiding the image to begin with, but not showing it when the button is pressed. Here's the code:</p>
<pre><code>function showImg() {
x=document.getElementById("map_img")
x.style.visibility="visible";
}
<body>
<img id="map_img" src="map.jpg" style="visibility:hidden" width="400" height="400"/>
<form id="form1" name="form1" align="center">
<input type="submit" id="Map" value="Map" onclick="showImg()"/>
</form>
</code></pre>
<p>I've also tried this in both situations:</p>
<pre><code><input type=button id="Map" value="Map" onclick="showImg()"/>
</code></pre>
<p>and:</p>
<pre><code><style>
.hidden{display:none;}
.show{display:block;}
</style>
function showImg() {
x=document.getElementById("map_img")
x.class="show";
}
<body>
<img id="map_img" src="map.jpg" class="hide" width="400" height="400"/>
<form id="form1" name="form1" align="center">
<input type="submit" id="Map" value="Map" onclick="showImg()"/>
</form>
</code></pre>
<p>I'm really lost as to how neither of these worked, could I get some help on this please?</p>

Making my application crash more gracefully
|
<p>I have an app that is running pretty stably (no more crashes actually), but as everybody knows your program crashes as soon as it gets in the hands of somebody else :D</p>
<p>What I would like is to find a(all) the place(s) where I can put a try{}catch(){} to be able catch and control what happens when the app crashes unexpectedly (display a better message, send log, possible recovery...)</p>
<p>I know its surely not that simple but still it would be good if there was a way to catch most of them.</p>
<p>(for example there is a small bug in GLSurfaceView that when it is being closed causes sometimes to crash because of an EGL swap buffer)</p>
<p>any ideas? </p>

rating system without reloading a page
|
<p>i have a page on which i have some rating function like people who like the post can rate up or who don't can rate down.</p>
<p>on that link im calling a php file with some parameters passed in the anchor tag. Then in that php file im saving that rating with +1 or -1 (whichever is the case) in the database and after doing that im redirecting to that first page from where we have rated.
Now this whole function is reloading my whole page which i dont want.Is there any way with which i can do this rating without reloading the page,i want that when a person clicks on rate then just after click the rating should be shown according to what the user just did(+ or -) and that too without reloading the whole page.Is there any way to do that in php???????</p>

how to change ListPreference default starting position

<p>I have a <code>ListPreference</code> that allows a user to select from a long list of items. (Only one item can be selected). When I re-open the list, the view defaults to showing the previously selected item at the top of the screen.</p>
<p>I was wondering if it was possible to enforce that the default position is always the top of the list, regardless of what item has been chosen.</p>
<p>edit - it seems like I will have to use a <code>ListActivity</code> and implement the preference changing capabilities myself?</p>

CGContext Draw Line slowly responding to fast finger movement
|
<p>I am using CGContext to draw lines on finger touch.
If the finger is moved slowly on the screen , it worked perfectly...but the problem is that if the finger is moved fastly , the line lags the finger. I mean the line draws at a point one second after the finger is touched at that point ( so annoying- it is not the problem on simulator but only on device).
Secondly if i draw a curve with that, the curve comes very angular - i mean curve is not very smooth

asp.net: How to get a button to affect the page contents
|
<p>In Page_Load I populate an asp:Table with a grid of images. I have a button that when pressed I would like it to repopulate the page with different images.</p>
<p>However it appears that when the button is pressed Page_Load is called again, followed by the script specified by the button. I thought that I could simply set a variable in the button script which is checked during Page_Load, but this will not work.</p>
<p>What is the most asp.netish way to approach this? Should I be populating my table somewhere other than in Page_Load, or should my button be doing something different?</p>

<p>I'm a newbie to javascript. I'm using firebug to debug my program and I got a "function is not defined" error. I searched online, and people said this is because of syntax error in the function. But that function is very big and I can't use firebug now (because it only gives me "not defined" error), is there any good way to debug it? Any tools to use? Thanks! </p>

jQuery: using live() with each()
|
<p>I have this function here:</p>
<pre><code>$("a.fancybox_vid").each(function(){
$(this).fancybox({
titleShow : false,

height: 395,
autoDimensions: false,
overlayOpacity: 0.6,
href: "misc/mc.php?v="+$(this).attr('id')
});
});
</code></pre>
<p>Now a link with c lass .fancybox_vid gets appended, and then this will not work. Only if it is there from the beginning. How can I have live() in this each().</p>

GConf Error: Failed to contact configuration server

<p>I have got this error while running in server.
<strong><em>GConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash.

object returns not defined in javascript
|
<p>Hi i am trying to get my head around some basic stuff in javascript, i want to create the equivalent to a class
see below:</p>
<pre><code>var myTest = {
myTester:"testing",
testCode:function(){
return myTester;
}
};
</code></pre>
<p>when i call <code>alert(myTest.testCode());</code> i get error myTester is undefined;</p>
<p>i also have similar trouble when trying to set the value of myTester too, what i am trying to achieve here is something along the lines of this:</p>
<pre><code>var myObj = myTest.testCode();
var tester = myObj.myTester;
</code></pre>
<p>as myObj is an object i should once created be able to access its values but i dont usually do javascript just jQuery and i am
trying to create an application in pure javascript just for brain feed and would appreciate a little guidence, especially on what do you actually call this, is it a class????</p>
<p>thanks</p>

Strings memory model
|
<p>What I read about strings is when a string object is created in Java it is immutable. For example:</p>
<pre><code>String s=new String();
s="abc";
s="xyz";
</code></pre>
<p>Does the <code>String s</code> no longer point to <code>"abc"</code>?</p>
<p>And another thing: what is size of s;
Is the <code>String</code> object analogous to a <code>char*</code> pointer in C in terms of the memory model?</p>

ArrayList returns same element for every index
|
<p>I suspect that the value being returned is the last one I have added to my arraylist.</p>
<p>I've got a class <code>Game</code> where the following function gets executed...</p>
<pre><code> public List<M> compute() throws CloneNotSupportedException{
G chil = (G) this.clone();
List<Move> Pm = new ArrayList<M>();
Point p;
for(/*condition*/){
//p is defined up here.basically loops through all possible values of p.
M m = pud.genM(chil, p);
Pm.add(m);
}
return Pmoves;
}
</code></pre>
<p>The strange thing is I'm doing a print on the values being returned for <code>m</code> and they are as expected (different) but when I loop through the List that has been created each and every element is equal to the last element that was added. It appears that this last to be added element is overriding all previous children...</p>
<p>The variable <code>pud</code> is of type <code>User</code>. The function being called is...</p>
<pre><code>public M genM(GameState g, boardPoint p){
M m; // a move
for(/*condition*/){
m = new M(/*parameters*/);
return m;
}
return null;
}
</code></pre>
<p>I've simplified this class down a fair bit, there's some if else conditions and an additional for loop but I took them out of this example because they're kind of messy and most likely irrelevant.</p>
<p>The object <code>M</code> is defined as...</p>
<pre><code> public M(String type, Point fPos, Point tPos, String input, G g){
this.type = type;
this.toPos = toPos;
this.fromPos = fromPos;
this.uInput = uInput;
result = new G(g);
//value of G gets edited here.
}

Instance variables, default being atomic
|
<p>I'm not quite sure if I understand atomic correctly. From what I read, it says that atomic is the default for the iPhone. Now is that for properties only, or any instance variable. For example, if I have an instance variable that I am going to write my own setters/getters, and do not declare it as a property, does that make that instance variable atomic? Is the downside mainly that it is optimized for threading, which my instance variable / application might not even need? Thanks.</p>

Slice vs Stride while reversing string
|
<p>Normally to reverse a list one should do the following:</p>
<pre><code>>>>>l = [1, 2, 3, 4, 5]
>>>>l[::-1]
[5, 4, 3, 2, 1]
</code></pre>
<p>But isn't the exact syntax like this:</p>
<pre><code>list[<start>:<end>:<stop>]
</code></pre>
<p>and if I don't give an optional parameter the defaults are as follows(Correct me if I am wrong:</p>
<pre><code><start> = 0(Beginning of list)
<end> = 5(Length of list)
<step> = 1
</code></pre>
<p>So if I give the optional parameters, it should in effect produce the same result:</p>
<pre><code>>>>>l[0:5:-1]
>>>>[]
</code></pre>
<p>But instead I get an empty list(and I know why this happening), but what are the default values being taken by python in the 1st case?It should take 0 and 5 as default and produce nothing, or is <strong>[::-1]</strong> different from <strong>list[start:end:stop]</strong></p>

Bug in Eclipse Emulator DDMS?

<p>I originally asked this question as a possible bug in Eclipse Helios :
<a href="http://stackoverflow.com/questions/3738526/possible-bug-in-eclipse-ddms-emulator-control">link text</a></p>
<p>I accepted that it was bug in Helios but I now find that I'm now getting the same error under Eclipse 3.5</p>
<p>When I send a location from the DDMS perspective using the emulator control tab. I have a standard listener:</p>
<p>onLocationChanged(Location location){...}</p>
<p>If I break on the first line of this, having sent the lat/lon pair of 53.5/-3.0 from the DDMS tab, then the mLatitude/mLongitude in the location argument have changed to 53.508833/-3.005000 (6 dec places only shown). </p>
<p>The Android SDK is 2.2 in both and the target is Google APIs level 7.
Does anybody else experience this or could offer a possible explanation? (It amounts to quite a big error in terms of metres on the map.)</p>

at the beginning of the packet in the end. Solution 1 I came up is pretty obvious to do
that but requires a second tmp variable which I do not really like.</p>
<pre><code>int size = 3;
int metadata = 4;
unsigned char * test = new unsigned char[size];
unsigned char * testComplete = new unsigned char[size+metadata];
test[offest1] = 'a';
test[offest2] = 'b';
test[offest3] = 'c';
set_first_4bytes(testComplete, val );
memcpy(&testComplete[metadata], test, size);
</code></pre>
<p>Another straightforward solution would be to do it the following way:</p>
<pre><code>unsigned char * testComplete = new unsigned char[size+metadata];
testComplete[offest1+metadata] = 'a';
testComplete[offest2+metadata] = 'b';
testComplete[offest3+metadata] = 'c';
set_first_4bytes(testComplete, val );
</code></pre>
<p>However, I don not like here the fact that each time I have the metadata offset to add so that I get the right index in my final packet. Is there another elegant solution which DOES not have the drawbacks of my approaches?</p>
<p>Thanks!</p>

timepicker: when to choose 24 or am/pm modes

<p>I have a few timepickers in my app.</p>
<p>In my country (Spain) we are used to displaying time in 24 hours mode... but in other countries are used to am/pm.</p>

Why does Java not permit the use of headers as in C++

<p>I have a question that I did not find an answer for except the following answer that does not meet my requirements:</p>
<blockquote>
<p>"Because James Gosling didn't want to"</p>
</blockquote>
<p>I know that Java can have interfaces (only pure virtual functions, no attributes), but it is not the exact same thing as class definitions.</p>

this pointer as a pointer to objects

<p>suppose employee is a class....print is its non-static member function which prints the value of its private data member x...now i read that if print is a constant function the this pointer passed to it by the compiler is of the type </p>

</blockquote>
<p>and if print is a non-constant function the type of this pointer is </p>
<blockquote>
<p>employee* const </p>

jQuery: difficult to add a symbol

<p>I do not know much about jQuery, that`s why I would like to ask you to help me to a add to my script the symbol of DOLLAR ($) as text. Need to mention that the script is working without dollar.</p>
<pre><code><script>
$(document).ready(function($){
var money = parseFloat($("#INSERTMONEY").val());
$('#costline').val((money).toFixed(2).text("$"));
})
</script>

Writing jQuery functions that allow chaining
|
<p>I want to write some code that allows me to replace jQuery's animate function with one that does different things, but still allows me to call a secondary function on completion.</p>
<p>At the moment, I'm writing lots of code like this;</p>
<pre><code>if (cssTransitions) {
$("#content_box").css("height",0);
window.setTimeout(function() {
secondFunction();
}, 600);
} else {
$("#content_box").animate({
height:0
}, 600, function() {
secondFunction();
});
}
</code></pre>
<p>I'd much rather write a function that looks like this:</p>
<pre><code>function slideUpContent(object) {
if (cssTransitions) {
object.css("height",0);
// Not sure how I get a callback here
} else {
$("#content_box").animate({
height:0
}, 600, function() {
});
}
}
</code></pre>
<p>That I could use like this:</p>
<pre><code>slideUpContent("#content_box", function(){
secondFunction();
});
</code></pre>
<p>But I'm not sure how to get the functionality I need - namely a way to run another function once my one has completed.</p>
<p>Can anyone help my rather addled brain?</p>

GROUP BY v.bezeichnung
ORDER BY total DESC
</code></pre>
<p>I have to implement it in JPA but everything works except GROUP BY... it can't be grouped..</p>
<pre><code>CriteriaBuilder builder = this.entityManager.getCriteriaBuilder();
CriteriaQuery<Veranstaltung> query = builder.createQuery(Veranstaltung.class);

query.groupBy(rootVeranstaltung);
List<Veranstaltung> result = this.entityManager.createQuery(query).getResultList();
return list;
</code></pre>
<p>I haven't finished the code yet, e.g. the COUNT..
should i write <code>COUNT</code> already before <code>GROUP BY</code> or would it work without <code>COUNT</code>?</p>

access the rowlistview programmatically

<p>I am trying to change the alignment of the text in <code>ListView</code> programmatically instead of changing the xml file.</p>
<p>Here is my <code>row_listview.xml</code></p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/textViewRowList"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_width="fill_parent"
android:textSize="20sp"
android:paddingLeft="6dip"
android:paddingRight="6dip"
android:gravity="left"
android:textColor="#330033"
android:textStyle="bold"/>
</code></pre>
<p>And <code>activity_main.xml</code> has following <code>ListView</code> defined there</p>
<pre><code><ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@null"
android:dividerHeight="0dp"
tools:listitem="@android:layout/simple_list_item_1"
android:background= "#FF6600">
</ListView>
</code></pre>
<p>So in my <code>mainactivity.java</code> I am trying to change the alignment of the text in listview at runtime when user clicks a button on my activity</p>
<pre><code>private ListView lv;
private TextView tvRowListView;
lv.setAdapter(new ArrayAdapter<String>(this,R.layout.row_listview, sampleStringArray));
tvRowListView = (TextView) findViewById(R.id.textViewRowList);
tvRowListView.setGravity(Gravity.CENTER);
</code></pre>

PHP error wrapper?
|
<p>I don't know if the term I'm using is right, but what I'm looking for is something similar to what you get with zend server. Take a look at <a href="http://static.zend.com/topics/zend-server-event-details-scr.jpg" rel="nofollow">this</a>.</p>
<p>It looks like on an error, it dumps the request along with a stack trace and function parameters as well as some other info. It lets you view it in a nice interface. I know this wouldn't be hard to make myself as you can always do error callbacks, but if something like this exists (for free) I'd prefer to use it instead of reinventing the wheel.</p>

How are Messengers garbage collected?
|
<p>Consider this code:</p>
<pre><code>Message message = Message.obtain(null, MSG_REQUEST_QUOTE, symbol);
message.replyTo = new Messenger(new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case StockMessengerService.MSG_QUOTE_VALUE:
callback.onQuote(symbol, msg.arg1);
break;
case StockMessengerService.MSG_QUOTE_FAILURE:
callback.onFailure(symbol, msg.obj.toString());
break;
default:
super.handleMessage(msg);
}
}
});
mService.send(message);
</code></pre>
<p>How is the JVM able to garbage collect the replyTo Messenger? In the Android javadocs, they only have a single Messenger, bound to the Activity. But this code works, but I'm quite curious how it is the JVM doesn't GC the Messenger before it gets its message, OR, whether this code is quite risky and will leak memory?</p>
<p>Edit2:
mService is like:</p>
<pre><code>private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder service) {
mService = new Messenger(service);
</code></pre>
<p>This is based on the sample code in the Service javadoc at <a href="http://developer.android.com/reference/android/app/Service.html" rel="nofollow">http://developer.android.com/reference/android/app/Service.html</a></p>

Script printing Blob works on one hosting site, not on another
|
<p>I've a script that prints images (Blobs from mysql DB). It works fine on Godaddy but when I move it to a UK hosting company it fails to print the image - prints the alt text instead (everything else works fine). GD is PHP 5.3 and the UK company is PHP 5.2. Both mysql DBs are 5. I have checked that the scripts are the same, correct data is in the DB etc.
I am at a loss as to where to look now.</p>
<p>The script is called with</p>
<pre><code>echo "<img src = 'printimage1.php?recipetableID=$recipetableID' alt='Picture does not display.'>";
</code></pre>
<p>and the printimage1.php script looks like</p>
<pre><code><?php
header("Content-type: image/jpg");
$recipetableID=$_GET['recipetableID'];
include("connect.inc");
$connection = mysql_connect($host,$user,$password)
or die ("couldn't connect to server");
$db = mysql_select_db($database,$connection)
or die ("Couldn't select database");
$query = "SELECT * FROM RecipeTable WHERE recipetableID = '$recipetableID'";
$result = mysql_query($query)
or die ("Couldn't execute query.");
while($row=mysql_fetch_array($result,MYSQL_ASSOC))
{
echo $row['Picture1content'];

Python:how to replace string by index

<p>I am writing a program like unix tr, which can replace string of input.
My strategy is to find all indexes of source strings at first, and then replace them by target strings. I don't know how to replace string by index, so I just use the slice.
However, if the length of target string doesn't equal to the source string, this program will be wrong. I want to know what's the way to replace string by index.</p>
<pre><code>def tr(srcstr,dststr,string):
indexes = list(find_all(string,srcstr)) #find all src indexes as list
for index in indexes:
string = string[:index]+dststr+string[index+len(srcstr):]
print string
</code></pre>
<p>tr('aa','mm','aabbccaa')<br>
the result of this will be right: mmbbccmm<br>
but if tr('aa','ooo','aabbccaa'), the output will be wrong: </p>

Android: handle onItemClick() in listView-based app
|
<p>I'm new to Android. I'm working on a listView-based app: you have a main menu, when you click an item, a new activity starts with another menu; when you click again, a new activity starts with the content you selected. Since I've quite a lot of menu items, I've to create a listener which handles all possible cases, so I've something similar:</p>
<pre><code> @Override public void onItemClick(AdapterView<?> listAdapter, View v, int position, long id) {
String text = ((TextView)v).getText().toString();
//main menu
if (text.equals(K.getStringById(K.ID_MAIN_THEORY))) {
...
} else if (text.equals(K.getStringById(K.ID_MAIN_EXERCISE))) {
...
}
else if (text.equals(K.getStringById(K.ID_MAIN_TABLES))) {
...
}
//here other menus' items: lots of items
...
//back item
else if (text.equals(K.getStringById(K.ID_BACK))) {
activity.finish();
}
Intent i = new Intent(...);
startActivity(i);
}
* K is a class that holds ids' references
</code></pre>
<p>There's a way I can avoid hard-coding listener behavior?</p>
<p>** PS: the lists' TextViews don't render properly: text appears light grey, not black! O.o</p>
