How to calculate/generate a string with all possible values in an array?
|
<p>This is driving me nuts but I've been struggling with this all noon now (im in GMT+2;)).</p>
<p>I want to do a fairly (I believed but realized it turned out otherwise..) simple task.</p>
<p>Lets say I have an array which looks like this:</p>
<pre><code>Array
(
[0] => Array
(
[OptionID] => 8748
[Values] => Array
(
[0] => 11614
[1] => 11615
)
)
[1] => Array
(
[OptionID] => 8749
[Values] => Array
(
[0] => 11616
[1] => 11617
)
)
)
</code></pre>
<p>This array is for generating all possible options with a product. Lets say OptionID 8748 means 'Size' and the Values in that array are 'L' & 'XL'. OptionID 8749 could be 'Color' with Values 'Red' and 'Black'.</p>
<p>I want to achieve the simple task to get the four unique combinations of that product in a string like:</p>
<p>11614+11616
11614+11617
11615+11616
11615+11617</p>
<p>But then, with a different product there could be a third product option, so it should be able to work arround with an unlimited depth.</p>

jquery divs in an array to display
|
<p>I have an array of <code>DIV</code> ids as following and in <code>CSS</code> they all below to a class with <code>display:none</code>.</p>
<pre><code>var paintDivs = ["div_2ndSubCategoryID","div_3rdSubCategoryID","div_4thSubCategoryID","div_ColorNameID","div_ColorNoID","div_PaintSizeID"];
</code></pre>
<p>Long story short, what I now want is to display all <code>DIV</code>s in <code>paintDivs</code>.</p>
<p>Below is what I have.
Loop iteration is working fine, however the individual <code>DIV</code>s in <code>paintDivs</code> are still not displaying.</p>
<pre><code>jQuery.each(paintDivs, function(idx, valIs){
$('#' + valIs).css('display');
});
</code></pre>
<p>I even tried by creating another class in CSS called, <code>showThis</code> and set <code>display:block</code> and tried to below, still didn't do the trick.</p>
<pre><code>jQuery.each(paintDivs, function(idx, valIs){
$('#' + valIs).attr('class','showThis');
});
</code></pre>
<p>What am I doing wrong? Any insight would be greatly appreciated.</p>

Error Handling URLS that do not exist

<p>I'm having problems with handling URLS that do not exist...</p>
<p>In my development environment, I navigated to <a href="http://localhost:XXXX/FakeLocation" rel="nofollow">http://localhost:XXXX/FakeLocation</a> and would catch the HttpException and handle it properly.</p>
<p>When I deployed to my production location, I'm getting a 404 error when I navigate to <a href="http://MyProductionURL/FakeLocation" rel="nofollow">http://MyProductionURL/FakeLocation</a>. How can I make the production location throw the HttpException so my code can handle it similar to how it works in my development environment?</p>

Also what do we generally follow? Creating a disclosure button in TableRow or not? </p>

how do i make hazelcast to store in my database using MapStore implementation
|
<p>I implemented MapStore and configured hazelcast so that it would know that when calling map.put it has to call in background .store from my implementation, at least that`s what i read.</p>
<p>If i use my implementation directly it stores what i what but if i call map.put it doesn't.
Can someone tell me why it doesn't or if i`m doing something wrong?</p>
<p>here is my MapStore implementation:</p>
<pre><code>public class MyMapStore implements MapStore<String, Object> {
private Session session = HibernateUtil.openSession();
@Override
public Object load(String key) {
// TODO Auto-generated method stub
return null;
}
@Override
public Map<String, Object> loadAll(Collection<String> keys) {
// TODO Auto-generated method stub
return null;
}
@Override
public Set<String> loadAllKeys() {
// TODO Auto-generated method stub
return null;
}
@Override
public void store(String key, Object value) {
Transaction tx = session.beginTransaction();
session.save((MyObject)value);
tx.commit();
}
@Override
public void storeAll(Map<String, Object> map) {
// TODO Auto-generated method stub
}
@Override
public void delete(String key) {
// TODO Auto-generated method stub
}
@Override
public void deleteAll(Collection<String> keys) {
// TODO Auto-generated method stub
}
}
</code></pre>
<p>and here is how i configure hazelcast:</p>
<pre><code>h.getConfig().getMapConfig("default").setMapStoreConfig(
new MapStoreConfig().setEnabled(true).setClassName(
MyMapStore.class.getName()).setWriteDelaySeconds(0));
</code></pre>
<p>if i print the hazelcast configuration it tells that all i setted is there so i don't know what`s wrong.
P.S. i'm using hazalcast 2.2</p>

HorizontalScrollView Inside an AlertDialog

<pre><code> <LinearLayout>
<HorizontalScrollView>
<LinearLayout>
<TextView></TextView>
<TextView></TextView>
<TextView></TextView>
<TextView></TextView>
</LinearLayout>
</HorizontalScrollView>
<LinearLayout>
</code></pre>
<p>I then set the adapter for my AlertDialog.Builder as my custom ArrayAdapter and also supply the OnClickListener. My dialog shows fine and I am able to scroll the list vertically as well as scroll each view horizontally. However, when I click on any of the views it never fires the OnClickListener. I have tried setting the top most LinearLayouts descendantFocusability="blocksDescendants" but that has no effect. Is there anyway to do this within the AlertDialog? I have tried even creating a custom Dialog that implements OnGestureListener but none of the gesture events ever get called either. </p>

Python: copy basemap or remove data from figure
|
<p>I want to use a basemap figure as a background and plot things ontop. As the generation of the basemap figure (a polar stereographic plot) is quite time intensive I only want to do this once. </p>
<p>The second step would be to draw some wind barbs on this plot and some other wind barbs on the same plot, but without the first set of barbs.</p>
<p>Now either I copy the background image and then draw two different images or I can remove the first set of barbs and then draw the second, I don't mind which way to go.</p>
<p>Unfortunately my brain is not helping me today and I am getting nowhere. I would be grateful for any tips.</p>

Can I determine PHP array value deltas?
|
<p>I have two multidimensional arrays that I need to determine the delta for each value. I know the array_diff function only returns the difference in keys. Is there a functon that will determine the delta for each set of values assuming the two arrays contain the same set of keys?</p>
<p>Example:</p>
<pre><code>array_1(test1 => Array([key1] => 100, [key2] => 200 ) )
array_2(test1 => Array([key1] => 105, [key2] => 195 ) )
</code></pre>
<p>I would expect something like:</p>
<pre><code>array_3(test1 => Array([key1] => 5, [key2] => -5 ) )
</code></pre>
<p>Are there any PHP methods to do this or am I on my own?</p>

PHP to text function
|
<p>I am trying to create a function that would parse php code and return the result in pure text, as if it was being read in a browser. Like this one:</p>
<pre><code>public function PHPToText($data, $php_text) {
//TODO code
return $text;
}
</code></pre>
<p>I would call the function like this, with the params that you see below:</p>
<pre><code>$data = array('email' => 'test@so.com');
$string = "<?= " . '$data' . "['email']" . "?>";
$text = $this->PHPToText($data, $string);
</code></pre>
<p>Now <code>echo $text</code> should give: <em>test@so.com</em></p>
<p>Any ideas or a function that can achieve this nicely?</p>

jQuery: How can I wrap an element with a table (consisting of multiple rows)?
|
<p>The jQuery <a href="http://api.jquery.com/wrap/" rel="nofollow">.wrap()</a> function allows you to wrap any matched elements with some custom HTML. However, the function doesn't allow you to indicate where in the HTML you would like you matched element to be inserted -- <strong><em>it is always inserted into the inner most element</em></strong>.</p>
<p>I need to wrap a div with a fairly basic table (in order to add rounded corners to it), but the only catch is that the table has two rows and I want my element to appear in the second row. For example:</p>
<pre><code>$("#my-div").wrap('<table> \
<tr> \
<td class="corner-topleft" colspan="2"></td> \
<td class="corner-topright"></td> \
</tr> \
<tr> \
<td class="corner-bottomleft"></td> \
<td class="DIV-SHOULD-APPEAR-HERE"></td> \
<td class="corder-bottomright"></td> \
</tr> \
</table>');
</code></pre>
<p>If you try to execute this script, the wrap() function automatically places the matched element inside the <strong>first table cell</strong> (i.e. "corner-topleft") as this is the "first inner most element".</p>
<p><em><strong>How can I use jQuery to wrap my element with the multi-row table above?</em></strong></p>

android multiple choice using images
|
<p>I have 10 images in an array which are answers to 10 questions which are also images in another array. </p>
<p>I have 10 image buttons coming up on my relative layout loaded with the 10 answer images. The answer array is answers[] and the questions array is questions[]. They correspond to each other, meaning that answers[1] is the answer to questions[1], and answers[4] is the answer to questions[4], and so on. I have a simple "for" statement which is <code>for(int i=0; i<=9; i++)</code>. </p>
<p>I want the 10 questions to come up one at a time, and let the user answer. I need the program to pause and let the user click the answer to the question. With that "for" statement, the first question which is questions[0] will pop up in imageview. Using if statements, I want to say "if the imagebutton with images[0] is clicked then I want an image to display that will say correct and do some other stuff, else I want an image to say incorrect and do some other stuff" and then I want it to pause until the user just clicks anywhere on the screen. </p>
<p>Can anyone help me with the pausing in the "for" statement to let the user answer, and the "if" statement where if the correct answer is picked I can display an image that says correct etc, and then pause again until the user just clicks anywhere on the screen?? Thanks!</p>
<p>By the way, I need those question images to pop up in the same imageview each time obviously, just changing the image.</p>

Time delay in Javascript
|
<p>Function PS.Tick() is called every 100 milliseconds and its job is to call AI function of NPCs so they can move:</p>
<pre><code>PS.Tick = function ()
{
"use strict";
for (NPCid = 0; NPCid < NPCnumber; NPCid++)
{
NPCAI(NPCid);
};
};
</code></pre>
<p>But I want the NPCs to not move simultaneously every 100 millisecond, but do it at their own frequency, so I tried this code:</p>
<pre><code>PS.Tick = function ()
{
"use strict";
for (NPCid = 0; NPCid < NPCnumber; NPCid++)
{
var timeout = 0;
timeout = PS.Random (1000);
setTimeout("NPCAI(NPCid)",timeout);
};
};
</code></pre>
<p>Now, they don't move at all. Why? How do I make them move at different time intervals?</p>

<p>I have a C# project - a class library - that produces a DLL file.</p>
<p>From within itself, this project runs an external .exe file. (Using the standard Process stuff, and it works fine.)</p>
<p>However, my question is: How can I bake the external .exe file into the project, such that the end-consumer will only receive the final DLL file, without ever seeing the .exe file itself?</p>
<p>This will make my client happier, as he will continue receiving one DLL file (as before, before I needed the .exe).</p>

Android - getting from a Uri to an InputStream to a byte array?
|
<p>I'm trying to get from an Android Uri to a byte array. </p>
<p>I have the following code, but it keeps telling me that the byte array is 61 bytes long, even though the file is quite large - so I think it may be turning the Uri <strong>string</strong> into a byte array, rather than the file :(</p>
<pre><code> Log.d(LOG_TAG, "fileUriString = " + fileUriString);
Uri tempuri = Uri.parse(fileUriString);
InputStream is = cR.openInputStream(tempuri);
String str=is.toString();
byte[] b3=str.getBytes();
Log.d(LOG_TAG, "len of data is " + imageByteArray.length
+ " bytes");
</code></pre>
<p>Please can someone help me work out what to do?</p>
<p>The output is "fileUriString = content://media/external/video/media/53" and "len of data is 61 bytes".</p>
<p>Thanks!</p>

Generate multiple DropDownLists
|
<p>I have to generate multiple dropdownlists on clientclick.
That is new dropdownlists on every client click.
I placed a button and wrote code on click event.</p>
<p>protected void addReq1_Click(object sender, ImageClickEventArgs e)</p>
<pre><code>{
DropDownList oDdl = new DropDownList();
oDdl.ID = "ddlReq" + (++i).ToString();
oDdl.DataSourceID = "DSUsers";
oDdl.DataTextField = "UName";
oDdl.DataValueField = "UName";
HtmlTableCell tc0 = new HtmlTableCell();
HtmlTableCell tc1 = new HtmlTableCell();
HtmlTableCell tc2 = new HtmlTableCell();
HtmlTableCell tc3 = new HtmlTableCell();
tc2.Controls.Add(oDdl);
HtmlTableRow tr = new HtmlTableRow();
tr.Cells.Add(tc0);
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
tr.Cells.Add(tc3);
search2.Rows.Add(tr);
}
</code></pre>
<p>Here "DSUsers" is SqlDataSource.</p>
<p>"i" is static variable.</p>
<p>"serarch2" is html table with runat server tag</p>
<p>The problem is only one control is getting rendred,
after that on every additional click same DropDownList is getting replaced.
No new DropDownList is added to the page.</p>

How to find out the path& filename to the application launcher icon declared in Android manifest
|
<p>I figured out that I can reuse my app's launcher icon inside my app, which is declared in the manifest as a launcher icon. I am doing this by simply calling the icon image from a layout xml file with the same file name and path as declared in the Android manifest.</p>
<pre><code>e.g.:
<ImageView
...
android:src="@drawable/ic_launcher">
</ImageView>
</code></pre>
<p><strong>The problem is:</strong> that if in the future I changed the icon's name/path in the manifest file, the code in the layout file would also need to be updated. Also, I would like to be able to reuse this piece of layout code in my next app without worrying about what filename & path has been declared in the manifest for the icon.</p>
<p><strong>Can I find out from my code the name&path declared in the manifest file for the launcher icon?</strong> This would allow me to read the manifest first then use the same name&path from the layout file.</p>

Bitshifting to read/write data

<p>I am sending 2 integers as one long in Java, and cannot work out for the life of me how to send these across properly using bit shifting.</p>
<p>I have a method to create the long:</p>
<pre><code>public long create(int one, int two){
return (one <<32 & two);
}
</code></pre>
<p>First of all, is this correct? (To send the two integers in one long together)</p>
<p>Secondly, if I want to then access either one or two, how do I go about that?</p>
<p>Is it a simple case of:</p>
<pre><code> public static int getOne(long theLong) {
return (int)theLong >> 32;
}
</code></pre>
<p>Or is there something a little more complicated?</p>
<p>Some guidance is much appreciated, thanks!</p>

<p>Now I'm faced with the challenge of figuring out how to differentiate between the various images I've loaded when I click on them so I can drag them around the screen.</p>
<p>Any ideas?</p>

How to print a list in Python "nicely"
|
<p>In PHP, I can do this:</p>
<pre><code>echo '<pre>'
print_r($array);
echo '</pre>'
</code></pre>
<p>In Python, I currently just do this:</p>
<pre><code>print the_list
</code></pre>
<p>However, this will cause a big jumbo of data. Is there any way to print it nicely into a readable tree? (with indents)?</p>

How to import a variable from different file types
|
<p>I am trying to obtain a variable from a different file type and import it into a Python script. The file is version.mk, it has a variable called VARIABLE_ID. The import module does not work as normally, is there any way to call variables from other file types?</p>
<p>Thanks for any help</p>
<pre><code>import os
from version import VERSION_ID
def versionid:
print VERSION_ID
</code></pre>
<p>This is the code that does not work.</p>
<p>The version ID is 0.0.2 format. When I run the below code it says there is a syntax error in the number.</p>
<p>I have read that distutils has a version numbering convention. I am not sure how this could be used, has anyone heard or know how this works?</p>
<p>Is there a way of having cooments in this file, when comments are in the file it interferes with the file. Could the read() just read the version_id and not the comments, thanks</p>
<pre><code>VERSION_ID=map(int,re.match("VERSION_ID\s*=\s*(\S+)",open("version.mk").read()).group(1).split("."))
</code></pre>

Existing library for quick menu like in Google+ app?
|
<p>A design pattern I've noticed being used recently in some Android apps is a simple textual list menu similar to QuickActions in that it pops up in a speech-bubble-like View when summoned. The Google+ app uses it for overflow items, for example.</p>
<p><img src="http://i.stack.imgur.com/E6b8C.png" alt="enter image description here"></p>
<p>Does anybody know of a library that'll let me easily implement these kinds of menus in my own app or, if not, what the most straightforward way of doing it from scratch would be?</p>
<p>Many thanks.</p>

How do I run javascript to revert what some code in an embedded script resource just did?
|
<p>So, I'm working on a mapping application. In the app there are these toolbars and based on certain circumstances I would like to disable specific tools. When a tool is disabled it's image changes. This part works fine.</p>
<p>Now, there is all this Javascript that is in embedded script resources that is ran when certain actions occur, like selecting a tool. I have no power over this Javascript.</p>
<p>What happens is some Javascript gets ran that essentially changes the image back from it's disabled one to it's default one. This is bad.</p>
<p>I'd like to know if there is any way to tell if the code from the script resource has ran or any way to see when the image has been changed so I can immediately change it back. Essentially over-riding the code in the script resource. </p>
<p>To word it differently, whenever this icons image changes from the disabled one to the enabled one via this specific javascript code, can I immediately change it back to the disabled image?</p>

What is the best way to handle processing in PHP from either logins or form posts
|
<p>I am pretty new to PHP and have yet to find really practical book which describes how to best process things in PHP in a real world situation, with security in mind. Even searching google, most articles are just about the basics, and are not real world examples. I just don't see anything good out there on PHP structure and flow for a website as a whole.</p>
<p>What I have adopted is for example, if a user fills out a login form in ABC.php, the data is posted to XYZ.php?do=processLogin . In XYZ, I have an "IF ISSET" for the "do" variable and if it's set then it enters a switch statement which handles logins, or logoffs, etc, and then redirects them back to the appropriate page. If the "do" variable is not set, they get dumped back to the login page.</p>
<p>I've seen many examples where data is posted to the same script, however just about anytime I am doing any sort of form processing or an action such as a login of logoff or account editing, I am posting to completely seperate PHP file to take care of that work, and then redirecting the user back. </p>
<p>Is this way sub-optimal, abnormal, stupid?? Can someone give me some advice on this, or link some good examples related to this topic? I was thinking lately of finding some open source app written in PHP so that I can view how an experienced PHP coder structures their site, so if anyone has an example of one of those to look at, that would be appreciated too.</p>
<p>Thanks in advance!</p>

PHP Mail/Postfix always returns true even when Postfix is stopped

<p>I have a weird problem. Using the mail() function and a local Postfix on the server. When Postfix is running, mail gets sent just fine but if I stop Postfix mail() still returns true but no e-mails are obviously sent and no error gets logged anywhere.</p>
<p>Code for sending:</p>
<pre><code>echo $accepted; //Returns 0
$accepted = mail($to, $subject, $message, $headers);
echo $accepted; //Returns 1
</code></pre>
<p>No other MTAs are running at the server.</p>

dialog.data.find(".confirmMessage").append(message);
dialog.data.find(".btnYes").click(function() {
$.modal.close();

What is a postback?
|
<p>The best explanation I've found for a postBack is from <a href="http://en.wikipedia.org/wiki/Postback">Wiki.</a></p>
<p><em>a postback is an HTTP POST to the same page that the form is on.</em></p>
<p>While the article does explain how a second page was needed in ASP, but no longer needed in ASP.NET, it doesn't give much detail or background. I am looking for a freakin' tome of information on PostBacks. Much like the simple question of "how can I clean a house" can be address by this <a href="http://rads.stackoverflow.com/amzn/click/068481465X">900 page book</a>. I don't need 900 pages worth, but details please. I found a nice little tutorial for ASP.NET life cycle, but it seriously glosses over postbacks (amongst other things). </p>
<p>I am looking to the developer's who have been around before .NET and really don't take these kinds of things for granted. Books and hyperlinks are reasonable answers or addition's to your answer.</p>

Trouble making android apps work for tablets
|
<p>I've got someone who wants to download an app to their Xoom, but when they go to download it, it says that the app is limitted to phones only. The android market settings say that the app is supported by the Xoom though, so I'm at a bit of a loss. Could this be a coding issue? The app was originally designed for API level 8, but I'd think it should be forward compatible... Xlarge screens are supported, as are all densities, but the Xoom still says that it can't download the app...</p>
<p>Anyone know what's going on here?

Need to reference a local variable before assigning
|
<p>I'm currently working on a permutation algorithm that will be used for a traveling sales person kind of problem. I have a method to calculate the cost of the cycle that will call a method (currentBest) to see if this permutation is better than currentBest one.</p>
<pre><code> def currentBest(newCost):
if newCost < currentBest:
currentBest = newCost
return currentBest
</code></pre>
<p>But the first time i run though this code currentBest will not have a value so i guess i have to assign it a value first but it has to remember the currentBest value for the other permutation so making a currentBest = 999 at the top of the code I don't think will work.</p>

<p>I knew that in JAVA "native" is a special thing. It can do a lot of things. But I'm not able to read it right now. I don't know how to... I knew it can call an other mathod in JAVA. My question is: can it call a private method? if it is a YES, then only in the same class or any other classes? if it can call other's, then is it a problem that maybe it's dangerous? that is, it broke the rules. Where can I get more about the NATIVE? can anybody show me a link?</p>
