Android wireless display
|
<p>I'm a fairly new android programmer and I've been having a rummage online about displaying an android screen over the network. I know it is possible to mirror the display using apps such as MirrorOp Sender. What I'm looking for is the android device to display one thing on the android device itself and something completely different on a screen elsewhere. So far my search results haven't gotten me very far. </p>
<p>So really what I want to know is, are there currently apps out there that can do this and are there any libraries out there that I could use to help me implement this? I have a few ideas on how I would go about implementing this but there is no point in me writing something from scratch if it has already been done.</p>

Trying to integrate Javascript range slider into my website but not sure where to start
|
<p>I am trying to build a little test shell for my website using Javascript. What I have at the moment is a normal website. PHP/HTML with an SQL backend.</p>
<p>What I'd like is a simple Javascript feature whereby the user has a single slider object and can use this object to set the upper and lower limit on a number of variables, which will be determined by a drop down box just underneath the slider.</p>
<p>Aside from this, I'd just like a number of checkboxes which dictate which products are displayed (i.e if I'd like food but not drink, the food checkbox would be ticked!).</p>
<p>I'm not expecting anyone on SO to do this for me, of course, but I would like to find some specific areas I could go to learn how to do this, and google is failing me in this regard. I will then begin working/editing this post to show my code/ask for help.</p>
<p>Can anyone help please?</p>

Is it possible to pass an "unnamed" variable to a function?
|
<p>Let's say there is the following function:</p>
<pre><code>void SetTheSize(const SIZE *size) { ... }
</code></pre>
<p>Is there any way to call that function without specifying the SIZE variable? e.g.,</p>
<pre><code>SetTheSize((const SIZE*)&{10, 10});
</code></pre>
<p><strong>edit:</strong>
I should had mentioned that the SIZE is a struct, without SIZE(int, int) constructor.</p>

How to set up Navigation Controller -> Root View in code (iPhone SDK)
|
<p>I need the ability to bypass the default RootViewController you get when you pick a navigation controller project type in XCode. I need this because I want to go down a different path depending on whether the app has been configured (sign up/login screens if not). Could someone point me to an example where in the AppDelegate the NavigationController is hooked to another controller (in this case SignupController) via code?</p>
<p>Here is what I have, but it doesn't let me change the title. And in the MainWindow.xib, it's still tied into the default RootViewController. </p>
<pre><code>(void)applicationDidFinishLaunching:(UIApplication *)application {
[[UIApplication sharedApplication]
// if no config, load up the SignupController
SignupController* signupController = [[SignupController alloc] initWithNibName:@"SignupController" bundle:nil];
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];

Unwanted carriage return when getting input from terminal
|
<p>I've just started learning Java and have come across a little quirk I'm not sure how to solve. It's the same as <a href="http://stackoverflow.com/questions/1123869/eliminating-the-new-line-when-using-bufferedreader-method-to-get-user-input-using">this</a> question but the solution there doesn't work here. The problem there was thought to be the result of something to do with Netbeans, and compiling the code form the command line may solve the problem, but I <strong>am</strong> compiling and running from the command line.</p>
<p>Basically, when I run the following code (snipped for brevity)</p>
<pre><code> System.out.println("Number: ");
line = in.readLine();
</code></pre>
<p>I get the following output:</p>
<pre><code>Number:
//Input cursor is found here
</code></pre>
<p>I'm running the code using the Gnome Terminal that ships with Ubuntu. Does anyone know what's causing this?</p>

How to save a state of a variable in android app and use it
|
<p>I have an android app which was built on eclipse. What i am currently doing is going through set of question in xml file randomly to ask. Xml file looks like this:</p>
<pre><code><item>
<ques></ques>
<option1></option1>
<option2></option2>
<option3></option3>
<ans></ans>
<level>1</level>
</item>
<item>
<ques></ques>
<option1></option1>
<option2></option2>
<option3></option3>
<ans></ans>
<level>1</level>
</item>
<item>
<ques></ques>
<option1></option1>
<option2></option2>
<option3></option3>
<ans></ans>
<level>2</level>
</item>
</code></pre>
<p>so on.... </p>
<p>Right now i am selecting question from level one randomly. Like there are 50 question in level 1 and 50 in level 2. I want to select question in order now. Like start from the top to bottom. Like if user A logs in plays the game he is being asked question a and b from level 1. Then he closes the game and logs back again so he should see c and d now.</p>
<p>My problem is how can this state be saved in android? Is there a easy way to do this?</p>

jquery or php detect external site length
|
<p>This might be pushing the limits here.</p>
<p>I iframe some external websites into one of my own websites. </p>
<pre><code><iframe style="margin-top:20px;width:99%;height:600px;" src="http://www.website.com/"></iframe>
</code></pre>
<p>This works just fine and dandy. However, sometimes the sites are much longer than 600px. Which is not to be unexpected.</p>
<p>Is there a way to detect the height, or some method of length detection that I could work with? </p>
<p>I don't expect this is possible, but I thought I'd ask.</p>

How to check if an array has an element at the specified index?
|
<p>I know there is array_key_exists() but after reading the documentation I'm not really sure if it fits for this case:</p>
<p>I have an $array and an $index. Now I want to access the $array, but don't know if it has an index matching $index. I'm not talking about an associative array, but an plain boring normal numerically indexed array.</p>
<p>Is there an safe way to figure out if I would really access an $array element with the given $index (which is an integer!)?</p>
<p>PHP may not care if I access an array with an index out of bounds and maybe just returns NULL or so, but I don't want to even attempt to code dirty, so I <em>want</em> to check if the array has the key, or not ;-)</p>

C++ XML-RPC Calling
|
<p>I haven't seen any documentation for calling XML-RPC by inputing certain strings and get respone of some strings in c++ by connecting to an XML API. This is a documentation provided by the server. I can't figure out how to do this</p>
<pre><code> A client can interact with a Pandorabot by POST'ing to:
http://www.pandorabots.com/pandora/talk-xml
The form variables the client needs to POST are:
botid - see H.1 above.
input - what you want said to the bot.
custid - an ID to track the conversation with a particular customer. This variable is optional. If you don't send a value Pandorabots will return a custid attribute value in the <result> element of the returned XML. Use this in subsequent POST's to continue a conversation.
This will give a text/xml response. For example:
<result status="0" botid="c49b63239e34d1d5" custid="d2228e2eee12d255">
<input>hello</input>
<that>Hi there!</that>
</result>
The <input> and <that> elements are named after the corresponding AIML elements for bot
input and last response.
If there is an error, status will be non-zero and there will be a human readable <message> element included describing the error.
For example:
<result status="1" custid="d2228e2eee12d255">
<input>hello</input>
<message>Missing botid</message>
</result>

My question is i am using two list boxes and one list box is populated by putting the list the list item tag in listBox1 on aspx page and i want to implement functionality like add and remove between two list boxes i mean removing an item from listBox1 should be added to second and removing an item from second should be added to first. While i tried my own but the problem is that on post back it come to same condition. I have implemented the add remove functionality by using the jQuery but the problem is that on post back it come to same condition so i want a good solution for this ow should i implement this so that on post back it retain it's value please ris me off from this issue.
I found some solutions for this on Google that i should make some other class which will extend ListBox base class but i couldn't understand that and how should i code for that so please explain me that code if possible.</p>

Using Python to convert color formats?
|
<p>I'm working on a Python tool to convert image data into these color formats:</p>
<ul>
<li>RGB565</li>
<li>RGBA5551</li>
<li>RGBA4444.</li>
</ul>
<p>What's the simplest way to achieve this?</p>
<p>I've used the <a href="http://www.pythonware.com/products/pil/" rel="nofollow">Python Imaging Library (PIL)</a> frequently. So I know how to load an image and obtain each pixel value in RGBA8888 format. And I know how to write all the conversion code manually from that point.</p>
<p>Is there an easier way? Perhaps some type of 'formatter' plugin for PIL?</p>
<p>Does PIL already support some of the formats I'm targeting? I can't ever figure out which formats PIL really supports without digging though all of the source code.</p>
<p>Or is there a better library than PIL to accomplish this in Python?</p>
<p>Any tips would be appreciated. Thanks!</p>

How do I open a website in browser through JAVA without having the browser open a new tab
|
<p><strong>Introduction</strong></p>
<p>I am making a proxy server in java. Whenever the user enters an unknown host (URL) in the browser, the proxy server handles <code>UnknownHostException</code> by executing the code below:</p>
<pre><code>try {
Process p=Runtime.getRuntime().exec("cmd /c start http://www.mysite.com/unknownhosterror.htm");
}
catch(IOException io) {
System.out.println("Error");
}
</code></pre>
<p>What these lines of code do is to display an html file containing "This page could
not be displayed." whenever the user entered a non-existing URL.</p>
<p><strong>Problem</strong></p>
<p>The code above opens a new tab and displays the content of www.mysite.com/unknownhosterror.htm. What I want is to redirect to it. </p>
<p>For example, I wrote www.nosuchsite.com in the URL bar. Suppose there is no such site, it will automatically redirect to www.mysite.com/unknownhosterror.htm and display "This page could not be displayed.".</p>
<p>How can I do this?</p>
<p><em>EDIT</em> NOTE: I do not use <code>Servlet</code>. </p>

Populating ComboBox and CheckedListBox from Database, C#
|
<p>Ok, as the title says, I'm trying to populate a combobox from a database, then change the contents of the checkedlistbox based on the change in the combobox. The problem here is, I'm about as lost as I could be. I decided to go with an access database (db1.mdb, in the same dir as the exe). The primary data table Table1 has the names of the items that should go in the combobox (item1, item2, item3). Then, I have separate tables for each value(tableitem1, tableitem2, tableitem3), and the listbox will be using these one at a time, listing the "Item Name" fields, of which there are varying amounts in each table. After checking off the options in the checkedlistbox, I need to grab the values from the other columns in that table "value1 and value2" from the database table associated with the checked list box. I've been programming for about 5 years, but have never needed to manipulate a database before, so I'm totally lost.</p>

Inner FutureTask in Java
|
<p>I try to implement an inner method in order to execute the following code in a new thread</p>
<pre><code>MyPojo result = null;
final MyPojo result2 = result;
FutureTask<MyPojo> runnableTask = new FutureTask<MyPojo>(
new Runnable() {
BindJSON<MyPojo> binding;
// Make the URL at which the product list is found
String sourceURLString =
"http://www.....ca/files/{CAT_ID}.json";
@Override
public void run() {
sourceURLString = sourceURLString.replace("{CAT_ID}", catId);
binding = new BindJSON<MyPojo>();
result2 = binding.downloadData(sourceURLString, MyPojo.class);
}
},
result2);
runnableTask.run();
</code></pre>
<p>So, now I take an error which says: The final local variable result2 cannot be assigned, since it is defined in an enclosing type. I take a look at this answer: <a href="http://stackoverflow.com/questions/5997953/cannot-refer-to-a-non-final-variable-i-inside-an-inner-class-defined-in-a-differ">Cannot refer to a non-final variable i inside an inner class defined in a different method</a> but it didn't work for me.
What should I do to make this work?</p>

How come when I use htmlentities() on my wamp server it works well, but has weird characters on someone else's server?
|
<p>I'm pulling an XML feed that doesn't specify the encoding. I can't change this on the feed.
When I use htmlentities(), it gives me a proper output for certain characters on my WAMP server, but when I upload it to another server, it seems like the encoding is incorrect for certain characters, like open and close double quotes (not just " but the one that looks like 66 and 99)</p>

Most elegant way to modify Python list elements inplace
|
<p>I have a 2D list that looks like this:</p>
<pre><code>table = [['donkey', '2', '1', '0'], ['goat', '5', '3', '2']]
</code></pre>
<p>I want to change the last three elements to integers, but the code below feels very ugly:</p>
<pre><code>for row in table:
for i in range(len(row)-1):
row[i+1] = int(row[i+1])
</code></pre>
<p>But I'd rather have something that looks like:</p>
<pre><code>for row in table:
for col in row[1:]:
col = int(col)
</code></pre>
<p>I think there should be a way to write the code above, but the slice creates an iterator/new list that's separate from the original, so the references don't carry over. </p>
<p>Is there some way to get a more Pythonic solution?</p>

find all items in list object
|
<p>I would like to interrogate all new emails (one by one) and find the contents of them so that I can use the contents for another application. </p>
<p>My first step was interpreting the return values from a search done via the search attr of an IMAP4 object. I'm trying to figure out what data is in a list that I have returned to me.<br>
How can I examine the object tree via print? Or, better yet, how can I get the contents of the email in a string?</p>
<p>For ex., I am returned the following via print:
<code>unseen email content: ['3 4']</code> from a variable named "response".
If I run <code>print response.__class__.__name__</code>, I get "list" returned.</p>
<p>I know that there is other data in "3", and "4", I just don't know what. </p>
<p>update: Specifically, this is the return of a call to an IMAP4obj.search(None, '(UNSEEN)')</p>

What's the point of os.error?
|
<p>Why does Python's <code>os</code> module contain <a href="http://docs.python.org/library/os.html#os.error"><code>error</code>, an alias for <code>OSError</code></a>?</p>
<p>Is there a reason to ever spell it <code>os.error</code>? <code>OSError</code> certainly seems more consistent with all the other built-in exceptions.</p>
<p>I hoped <code>os.py</code> would shed some light, but it uses <code>error</code> sometimes and <code>OSError</code> others.</p>
<p>It seems goofy to have an extra name for one of the exceptions, yet it survives into Python 3.0. What am I missing?</p>

|
<p>Is there any way I can find how many objects are instanciated from stack and how many objects from Heap. I dont wish to have the restrictions of scoping in objects from Stack.</p>
<p>If i use a static counter in constructor and destructor, it will be called in both the cases(object from stack and heap). One way is to exploit the idea are objects from stack are scoped and destructor is called when they go out of scope but i want a better solution so as to know the number of objects at any point of time.</p>

Embedding a Resource in C#
|
<p>I'm using the AxShockwaveFlash object to load an extern .SWF file into my C# application. The AxShockwaveFlash takes in a URL for the movie to load. To load a local file, I can use a file:/// url string, which works fine.</p>
<p>However, I'd really prefer that the SWF be embedded in the compiled executable, but the the AxShockwaveFlash object requires the string url to load.</p>
<p>Does anyone have any good ideas on how this can be achieved, short of writing the file to a location on the computer when the executable is run?</p>
<p>Thanks.</p>

getting parent index with jquery

<p>I know there is another question with an answer to my question, however one solution that was said to be newer does not work for me.</p>
<p>so I have something like: </p>

<li><div class="thumb"></div></li>
<li><div class="thumb"></div></li>
</ul>
$("ul li div.thumb").live("click",function(){
alert($(this).parent().index());
});
</code></pre>
<p>I want to retrieve the index of the li, however the solution is not working for me.</p>
<p>EDIT:</p>
<p>Ok my actual code has children within div.thumb:</p>
<pre><code><ul>
<li><div class="thumb"><div class="inner">3</div></div></li>
<li><div class="thumb"><div class="inner">3</div></div></li>
<li><div class="thumb"><div class="inner">3</div></div></li>
</ul>

c++ how to deal with method returning either NULL or std::string?

<p>I am a bit stuck with some code. I have to use the return type of the method <code>getToto()</code> which usually returns a <code>std::string</code>, but in one case it returns <code>false</code> (It is part of a library I have to use, I cannot modify it). I understand that is equivalent to a null pointer. But I cannot find a proper way to catch it!</p>
<p><strong>Test.cpp</strong></p>
<pre class="lang-cpp prettyprint-override"><code>static std::string getToto(){
char buffer[1024];
if ( CTX_Get_Env(buffer, "Toto", 1024) )
return false;
return buffer;
}
</code></pre>
<p>If I try</p>
<pre class="lang-cpp prettyprint-override"><code>const char* returned = Test::getToto().c_str();
if (returned==NULL){
std::cout<< "null pointer"<<std::endl;
}
</code></pre>
<p>I get an error whilst running</p>

PHP Loop Over ONLY Different Arrays
|
<p>I have a single array with several of the same values. And I only want to loop over DIFFERENT values. How could I go about doing this?</p>
<p>Example</p>
<pre><code>166-01 001;09;UO;
166-01 001;09;UO;
166-01 001;09;UO;
166-01 001;09;UO;
166-01 001;09;UO;
166-01 001;09;UO;
166-01 001;09;UO;_86
166-01 001;09;UO;_86
166-01 001;09;UO;_86
166-01 001;09;UO;_86
166-01 001;09;UO;_86
166-01 001;09;UO;_86_97
166-01 001;09;UO;_86_97
166-01 001;09;UO;_86_97
166-01 001;09;UO;_86_97_108
166-01 001;09;UO;_86_97_108
166-01 001;09;UO;_86_97_108_119
166-01 001;09;UO;_86_97_108_119
</code></pre>
<p>I have that in a single array, but I only want to loop for the different ones. So it would loop once for nothing, then once for _86, then once for _86_97, then once for _86_97_108, and then once for _86-97_108_119. So only loop for different key values, </p>
<p>or would there be a way to count the number of different keys?</p>

Horizontal line padding
|
<p>I'm trying to add a horizontal line between two EditText widgets, but strangely the line has no padding at the bottom, so it appears "glued" to the widget that is below it.</p>
<p>This is my code (in the layout.xml, inside a LinearLayout with vertical orientation):</p>
<pre><code> <EditText android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:capitalize="sentences"
android:singleLine="true"
android:maxLength="30" />
<View android:background="#FF00FF00"
android:layout_width="fill_parent"
android:layout_height="1dip" />
<EditText android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:scrollbars="vertical"
android:capitalize="none"
android:autoLink="all"
android:maxLines="8" />
</code></pre>
<p>And this is how it looks like:</p>
<p><img src="http://i.stack.imgur.com/Ceg4D.png" alt="enter image description here"></p>
<p>I'd like to add some padding below the line. I tried with android:paddingBottom in the View widget, and with android:paddingTop in the below EditText widget, but the result is the same (it's ignored).</p>

class B : A { public int test = 8; }
class Program
{
static void Main(string[] args)
{
A test1 = new A();
A test2 = new B();
Console.WriteLine(test1.test);
Console.WriteLine(test2.test);
}
}
</code></pre>
<p>This displays 7 in both case when I'd like it to display 8 in the 2nd case....</p>
<p>I've tried virtual and override as well as new (public new int test = 8;)
But it doesn't seem to work</p>
<p>And yes I know I should use private and getters. I just want to know if it's possible ?</p>

iPhone app pricing model question?

It was a comparison between having a free application supported by ad vs a .99 cent application. .99 cents seems to be the sweet spot for a lot of the smaller applications. Anyone know where those studies were done? Are people having better success with .99 cents or the free ad supported applications?</p>

How to design good looking Web Application
|
<p>I am a java developer and I am on my way to create a professionally good looking web application, one which has jquery, and fancy menus, well organized css, html etc. I have little knowledge of CSS, html, javascript and other web <strong>designing</strong> languages. </p>
<p>Please let me know how developers create such kind of websites that have good look and feel.</p>
<p>I dont want to use GWT/Wicket/or any other java framework. Just the traditional html and javascript as they are way faster than java based web UI frameworks.</p>
<p>Also let me know if there is any IDE to easily design the website. I use eclipse. can it be done on eclipse.</p>

<p>i have a list with duplicate elements:</p>
<p>In python:</p>

tmp=[]
for i in list_a:
if tmp.__contains__(i):

<p>i have used the above code to found the duplicate elements in the list_a.
i dont want to remove the elements form list.</p>

Normally C/C++ we use like this i guess:</p>
<pre><code> for (int i=0;i<=list_a.length;i++)
for (int j=i+1;j<=list_a.length;j++)
if (list_a[i]==list_a[j])
print list_a[i]
</code></pre>
<p>how do we use like this in Python ?</p>
<pre><code>for i in list_a:
for j in list_a[1:]:
....

PHP not stripping slashes when echoing
|
<p>I'm hoping someone can clear this up for me. I have been reading a book on best practices when it comes to form validation and that if the user enter a wrong value return the form back to them with the data they entered with warning/error messages. </p>
<p>What I want to do is say a user enters the below into a text box: </p>
<pre><code>hello " there
</code></pre>
<p>I want to return the above in the text box. Now when I use the below code it adds a slash. </p>
<pre><code><input name="name" id="name" type="text" class="formbox"
<?
php if ($missing || $errors) {
echo 'value="' . htmlentities($name) . '"';
}
?>
>
</code></pre>
<p>What I considered doing is this:</p>
<pre><code><input name="name" id="name" type="text" class="formbox"
<?
php if ($missing || $errors) {
$name = stripslashes($name);
echo 'value="' . htmlentities($name) . '"';
}
?>
>
</code></pre>
<p>While the above works it seems inefficient. If I use just 'stripslashes' then anything after the " is removed. Currently the form is just checking its self in the sense that when the user clicks submit the form reloads and an IF statement catches any posts which then checks to see if there are any missing fields.</p>
<p>I hope this all makes sense as I have been unable to find a best solution on SO and Google.</p>
<p>Many thanks for any help in advance :) </p>

Collect all method args in an Object[] array
|
<p>I'm looking at collecting all the method parameters of generic methods in an Object[] array for logging purposes. I'm aware that this is better achieved using aspects, but am disallowed from using it and am looking for a pure reflection based approach if possible</p>
<p>To clarify,
Assuming a method call</p>
<pre><code>class A {
foo(int a, Object b){
}
}
</code></pre>
<p>Given an object instance of A, is it possible within the 'foo' method to dynamically determine the arguments that were passed? I cant seem to find any API in java.lang.reflect or annotations to determine this.</p>
<p><strong>EDIT</strong>: I currently use the implementation below for logging. However it's tedious to collect all method params in an array before calling it and was wondering if this could be inferred somehow. I'm looking for any suggestion/library other than aspects </p>
<pre><code>private static final ConcurrentMap<Class, Method[]> METHODS = new ConcurrentHashMap<Class, Method[]>();
protected void log(Class clazz, String methodName, Object[] args) {
Method[] methods = METHODS.get(clazz);
if (methods==null){
methods = clazz.getDeclaredMethods();
METHODS.put(clazz, methods);
}
for(Method method:methods){
if (method.getName().equals(methodName)){
StringBuilder builder = new StringBuilder(methodName + '(');
int i=0;
for (Class type:method.getParameterTypes()){
builder.append(type.getSimpleName())
.append(" [")
.append(args[i++])
.append("] ,");
}
String str = StringUtils.removeEnd(builder.toString(), ",") + ")";
LoggerFactory.getLogger(clazz).info(str);

C++ Array Member of Constant Length (Initialisation of)
|
<p>I have a class that contains an array. I want this array to be set at the length of a constant:</p>
<pre><code>// Entities.h
class Entities
{
private:
const int maxLimit;
int objects[maxLimit];
int currentUsage;
public:
Entities();
bool addObject(int identifier);
void showStructure();
};
</code></pre>
<p>The main problem I'm having is with the constructor. I thought:</p>
<pre><code>// Entities.cpp
Entities::Entities() : maxLimit(50)
{
currentUsage = 0;
cout << "Entities constructed with max of 50" << endl;
}
</code></pre>
<p>would have been sufficient...but not so. I don't know if I can use the initialiser list for array initialisation.</p>
<p>How can I initialise the 'objects' array using the 'maxLimit' const? I'm relatively new to classes in C++ but I have experience with Java. I'm mainly testing out this phenomenon of 'constness'.</p>

Expand/collapse group nodes in ExpandableListView based on passed Cursor values?
|
<p>I've got a ExpandableListView widget that is populated using an adapter based on the SimpleCursorTreeAdapter as shown below. I I query my SQL database for the ListView's group titles as well as a boolean value to whether the group should be expanded or collapsed (which is returned in a Cursor). I then feed this Cursor to my adapter and the list is populated and displayed.</p>
<p>The only thing I can't do, is have the group nodes in the ListView be expanded or collapsed based on the boolean value in the supplied Cursor. I want to have this happen when the activity containing this ExpandableListView widget is initally created, loaded, and displayed.</p>
<p>Is there a way to have my adapter take the boolean values supplied in the Cursor object and use them to expand or collapse these group nodes?</p>
<pre><code>public class MyExpandableListAdapter extends SimpleCursorTreeAdapter
{
public MyExpandableListAdapter (Cursor cursor, Context context, int groupLayout,
int childLayout,
String[] groupFrom, int[] groupTo,
String[]childrenFrom,int[]childrenTo)
{
super(context,cursor,groupLayout,groupFrom,groupTo,childLayout,childrenFrom,childrenTo);
}
@Override
protected Cursor getChildrenCursor(Cursor groupCursor)
{
String strCategory =
groupCursor.getString(groupCursor.getColumnIndex("strCategory"));
Cursor cur = mainActivity.mDbHelper.getCardTitlesForCategory(strCategory);
return cur;
}
}

<p>I receive the header fine, but then the client just hangs forever because the server never finds "EOF" of the request. How do I handle this? I've seen this question asked quite a bit, and most solutions involve something like the above, however it's not working for me. I've tried using both curl and a web browser as the client, just sending a get request</p>
<p>Thanks for any ideas </p>

Possible to make a self contained web part that uses jQuery?
|
<p>Basically I would like to create a WebPart that uses jQuery but I don't want to have to add jQuery to my masterpages (or anywhere else) manually. I would like to have one WSP that I could email to someone, have them install only that, and having a working WebPart that uses jQuery.</p>
<p>Is this possible?</p>
