I need to make a split-view inside a navigation because I need to make a login system. After login, then we can see the split view.
I found that someone say must need to set it to be root view, some say do not need. However I cannot do it in both way.
Can anyone teach me how to do that step by step??

So I decided to switch over to libc++ (to use std::array and such) but I was using boost (specifically asio and regex), so I had to recompile boost using libc++. I removed boost which was installed in macports and build boost from source and now is installed in /usr/local/include and /usr/local/lib. Ever since then, I cannot compile. Here are the oddities I am encountering:
When executing:
clang++ -g -std=c++11 -stdlib=libc++ -c main.cpp
I get a weird compile error having to do with the move constructor (there's more to this error, but as you can see it is coming from boost):

However, when I execute (please note the "-I", and it must be in that exact position):
clang++ -I -std=c++11 -stdlib=libc++ -g -c main.cpp
This compiles (but linking fails later on). Why is this? What does -I do without a path? Must -stdlib= be preceded with -I?
Now the fun part:
Even though, everything compiles now, it won't link. When executing:
clang++ main.o FTPClient.o FTPConnection.o -lboost_system -lboost_regex -std=c++11 -stdlib=libc++ -g -o cli
I get the message:

please advise how to fix this issue. | 0 |

I have also tried substituting {{msg}} with:

The rest of the page outputs fine, Django does not throw an error. The console does not contain anything abnormal. The HTML code produced does not contain the div, nor the list tags anywhere. The template which this one extends (base.html) does not use the {{messages}} variable nor call a template tag which uses it.
I have tried passing the {{messages}} into a custom template tag for testing in the top of the index.html template. Here I can do:
def __init__(self, messages):
self.messages = messages
def render(self, context):
l = dir(context[self.messages])
print(l)
...which produces a list of methods / properties presumably of the message object. Yet, I cannot iterate over this at all, as "for m in messages:" does not run even once. Attempting to discover the size of this entity by:
print(len(context[self.messages]))
gives me nothing in the console.
The only time I've got it to actually output anything was when I manually passed the messages object into the template within the render_to_response tag then iterated over messages.error ({% for msg in messages.error %}) which produced two bullet points in the correct div: the first being filled with what looks like a var dump: "<WSGIRequest path:/admissions/, GET:<QueryDict: {}>, POST:<QueryDict: {}>, COOKIES:{'csrftoken':"... the second bullet point containing just the last error message: "Why won't this f***ing thing work?". (Obviously this was just a test and I have not kept messages in the dict passed via render_to_response as I know it should arrive in the template via the context)
So, where did I go wrong?
Why can I not see my error messages in my template? Why can I not even get the messages to appear in the console?
Any light someone smarter than me can shed would be extremely helpful!

Sometimes the soundcloud popup disappear after 1 second, other times, nothing appends, the UI stay in this state (with the spinner active).
In the console, I've got this error message :

On the soundcloud website I put an URI like this one myApp://oauth2, and I wrote the same in the initialize method.
I'm not sure it worked, because when I refresh the editing page, the redirect URI field is blank...
Any idea ?
I'm trying to login to soundcloud with this code :
[SCSoundCloud requestAccessWithPreparedAuthorizationURLHandler:^(NSURL *preparedURL){
SCLoginViewController *loginViewController;
loginViewController = [SCLoginViewController
loginViewControllerWithPreparedURL:preparedURL

===
I'm developping an iOS app which use soundcloud API.
I followed this tutorial : https://github.com/soundcloud/CocoaSoundCloudAPI
Everything was fine until the login step.. I try to upload a song (just to try something different), but I had the same result... No fields to logged in.
Sometimes the soundcloud popup disappear after 1 second, other times, nothing appends, the UI stay in this state (with the spinner active).
In the console, I've got this error message :
> Ooops, something went wrong: Redirect URI mismatch
On the soundcloud website I put an URI like this one myApp://oauth2, and I wrote the same in the initialize method.
I'm not sure it worked, because when I refresh the editing page, the redirect URI field is blank...
Any idea ?
I'm trying to login to soundcloud with this code :
[SCSoundCloud requestAccessWithPreparedAuthorizationURLHandler:^(NSURL *preparedURL){
SCLoginViewController *loginViewController;
loginViewController = [SCLoginViewController
loginViewControllerWithPreparedURL:preparedURL
completionHandler:^(NSError *error){
if (SC_CANCELED(error)) {
NSLog(@"Canceled!");
} else if (error) {
NSLog(@"Ooops, something went wrong: %@", [error localizedDescription]);
} else {
NSLog(@"Done!");
}
}];
[self presentModalViewController:loginViewController
animated:YES];
}];
Thanks !

- created two icons for the start point and the end point.
- in rendererOptions set suppressMarkers: false
- then placed those two marker to the start point and the end point of the path
So now I have my customary created icons at the two ends.
But my requirement is these markers should be draggable. so i set the **draggable: true** and now its working fine.
But now my problem is while dragging the icon, the path should be changed dynamically, which should be similar to that of
https://google-developers.appspot.com/maps/documentation/javascript/examples/directions-draggable
I tried to do this by adding listeners to those two markers : "drag" event - and while dragging a marker, draw the path at the same time. But the result I'm getting is not similar to the "directions-draggable" example. In facts, although i can render paths, previously drawn paths still exist on the map. But clearing all the paths exist on the map and then re-draw all is not my requirement.
So is there a way to get the same result/effect like the "directions-draggable" while changing the marker icons.
thanks in advance...

At that rate, the moderately priced [RedisToGo][1] instance will fill up every hour or so.
The logs are only necessary to generate daily\monthly\annual statistics: which was the top requested keyword, which was the top requested url, total number of requests daily, etc. No super heavy calculations, but a somewhat time-consuming run through arrays to see which is the most frequent element in each.
If I analyze and then dump this data (with a setInterval function in node maybe?), say, every 30 minutes, it doesn't seem like such a big deal. But what if all of sudden I have to deal with, say, 2500 requests per second?
All of a sudden I'm dealing with 4.5 ~Gb of data per hour. About 2.25Gb every 30 minutes. Even with how fast redis\node are, it'd still take a minute to calculate the most frequent requests.
Questions:
What will happen to the redis instance while 2.25 gb worth of dada is being processed? (from a list, I imagine)
Is there a better way to deal with potentially large amounts of log data than moving it to redis and then flushing it out periodically?

I've used the O'Reilly tutorial to do this. However, I can get past this error: Modal session requires modal window.
The window loads as a window if I have "Visible At Launch" checked.
Whether it is checked or not I get the "Modal session requires modal window" error.
I have a Window.xib, ProgressModal.xib.
In the Window implementation file I use:
-(IBAction)loadProgress:(id)sender{
[self progressStatus:progressWindow];
}
- (void)progressStatus:(NSWindow *)window {
[NSApp beginSheet: window
modalForWindow: mainWindow

[NSApp runModalForWindow: window];
[NSApp endSheet: window];
[window orderOut: self];
}
- (IBAction)cancelProgressScrollView:(id)sender {
[NSApp stopModal];
}
I may have the ProgressModal.xib setup wrong. I have an NSObject in it that has "Window" as its class. All the connections are made through that.
But again, it loads the window just won't load it as a modal.

This works ok for most of the simple transactions, however, now I need to test a method which utilises the RetrieveAttributeRequest message from the SDK to retrieve OptionSetValue labels. To be able to Mock the returned object would require knowledge of exactly how this method is retrieving the attribute data, but I have not been able to find this information.
1) Is this the correct way to approach this problem, or are we left with an integration test as the main option.
2) If this is valid then which table is the data requested from?

After focus lost from text field first swing worker (lets assume it as sw1) is called. Which opens a pop-up to populate value to put in text field. Second swing worker (lets assume it as sw2) is called after user clicks a button.
Now the issue is that if I write something in text field and then click on button, sw1 is started first to calculate the value to put in text field and at the same time sw2 is also started. And sw2 finishes first and then sw1 populates result. What I want is sw2 should wait for sw1 to finish. Once sw1 finishes its task, it will notify sw2.
I referred so many references over the internet and stackoverflow. [This](http://stackoverflow.com/questions/915873/scheduling-swingworker-threads) is the one which almost matches to my requirement.
I tried to create a static final object inside class which starts sw1:
public final static Object lockObject = new Object();
Then inside done() method of sw1, I have written code like:
synchronized(lockObject) {
sw1.notifyAll();
}
Inside doInBackground() method, of the second class, on first line, I have written code like:
synchronized(FirstClass.lockObject) {
try {
sw2.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
But I am getting java.lang.IllegalMonitorStateException, at java.lang.Object.notifyAll(Native Method). Can anybody tell me what is the issue and how to make it work the way I want.

The scenario is this, I am pulling all my events from an external database using a webservice, so all the events come with an ID.

The problem is, when I retrieve the event I need it to have the same id as the event on the server so I can do a quick look up to get additional info on the event. I am aware that the identifier property of EKEvent is read only, hence the reason I want to create a subclass of the class where I can add an additional property called something like myid and store the id of the event (the one from the server) with it in the eventstore. I have tried to create a subclass and everything seems to work fine and compiles, but on runtime I get an error when I try to set the extra eventid proporty that I add in the subclass, the error message is:

The error occurs on the last line ` myEvent.eventId = self.eventId;`
and app crashes. So my question essentailly if I can effectively subclass the EKEvent class and if so what am I doing wrong here?

what is the best structure for my urls (and why please), I have some examples:

note: all url parts can grab related data - for example
www.sitename.com/used/cars/ - will forward to a page contains all used cars
www.sitename.com/used/cars/{make-name}/ - will forward to a page contain all cars from this maker only

It works great when the body of the HTML is small and quick to render, but for larger bodies, you'll find that the animation runs immediately when the content loads, but the `UIWebView` is not painted on to the view for another second or so, which means the user misses the animation completely.
So my question is, rather than have the fade animation occur on load, I want it to occur when the web view is actually drawn on to my view, and I don't think there are any Objective-C delegate methods that are called when the web view is drawn, so I'm not sure if this can be done on the Objective-C side.
Is there anyway I can call some Javascript (this way I can add the animation manually) immediately when the the web view is actually drawn on my device, rather than when `webViewDidload`? | javascript | css | ios | uiwebview | null | null | open | CSS load animation on UIWebView

I'm trying to find a selector in jQuery that select all inputs that are checkboxes and their name contains a specific word like "top" or "Top". Having trouble b/c its selecting other checkboxes.
Is it possible to use something like:
$("input[name*='top'] type:checkbox").each etc?
Top 1<input type="checkbox" name="Top1" /><br />
Top 2<input type="checkbox" name="Top2" /><br />
Top 3<input type="checkbox" name="Top3" /><br />
Top 4<input type="checkbox" name="Top4" /><br />
Bottom 1<input type="checkbox" name="Bottom1" /><br />
Bottom 2<input type="checkbox" name="Bottom1" /><br />
Bottom 3<input type="checkbox" name="Bottom1" /><br />
Bottom 4<input type="checkbox" name="Bottom1" /><br />
I only want to select the check boxes which contian the word "top" in its name.

"editable" for the UITextView is turned off, which allows me to set dataDetectorTypes to UIDataDetectorTypeAll, which is exactly what I want. The app now detects when the user touches a link in the UITextView, and does the appropriate thing.
The problem arises when the user touches on part of the UITextView where there is no link. I want the didSelectRowAtIndexPath in the UITableView delegate to be called. But it isn't, because the UITextView is trapping the touch, even when no link is detected.
My first guess was to turn userInteractionEnabled on the UITextView to NO. This means that didSelectRowAtIndexPath will get called, but then the UITextView can't detect links. It's a catch-22.
Any ideas on how to fix this?

Within this repeater I have a ListBox control. I'm binding a list of Applicaitons to the ListBox, and then I'm binding a list of Roles for the application to the ListBox.

`SetUser` is doing all the binding for my repeater. It gets the list of applications, the list of associated roles, and selects the appropriate roles the user has currently.

If I search for another user and select them, the code behind still looks to be executing properly, but the view is not updated.

It requires you to use a `collect -j` command to run the `java` JVM.
Unfortunately, GlassFish appears to allow you to change only the Java home. In `./config/asenv.conf` there is an entry for `AS_JAVA`.
I tried to `start-domain` and capture the long Java command line there. However, it appears to hang.
Is there a way to change the JVM command line program? Hopefully, without hacking on the GlassFish scripts.

A bug in my code hashes byte sequence generated from a String with JVM's default encoding and I need to verify whether that will cause hash collisions when the code is run with different strings and different JVM file encodings (which can happen when run on Windows and Linux for example).
Since an encoding is a mapping between byte sequences and characters, I think there may be some strings and encodings that pass the above test. But just wanted to know if there are any well known examples or some good reasons for why I shouldn't be relying on hash collisions not happening.

@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "dtype")
public abstract class MetaFieldValue<T> implements Serializable {
private Integer id;
private MetaField field;
@Transient
abstract public T getValue();
abstract public void setValue(T value);
}
public class StringMetaFieldValue extends MetaFieldValue<String> {
private String value;
}
Although, I have a large query querying with the help of hibernate, in nutshell it is doing the following
MetaFieldValue.createCriteria().list(max: 10, offset: 0){
ilike("value", "100");
}
which does not seem to get the desired effect as the query
StringMetaFieldValue.createCriteria().list(max: 10, offset: 0){
ilike("value", "100");
}
The first query gives me an exception
groovy.lang.MissingMethodException: No signature of method: static com.sapienter.jbilling.server.metafields.db.MetaFieldValue.createCriteria() is applicable for argument types: () values: []
But the second query gives the result
[MetaFieldValue{name=MetaField{id=1, name='partner.prompt.fee', entityType=CUSTOMER, dataType=STRING}, value=100}]
which is the result I want.
So, my question is that how can I achieve the same effect using the **superclass** rather than any of its **sub-classes** ?
