When I run the following code, the NSArray `sortedFinPeriodsDesc` contains the faulted periods in the correct sorted order. However, when accessing them in the `for each` loop, each of the periods returns nil for its attributes, and in particular, nil for its EndDate. For this reason my method `lastReportedPeriodforDate` always returns nil, which is an error.
#import "IBCompany+FinstatAccessors.h"
@implementation IBCompany (FinstatAccessors)
NSArray *sortedFinPeriodsDesc;
- (IBFinPeriod*)lastReportedPeriodforDate:(NSDate*)date;
{
if ( !sortedFinPeriodsDesc ) {
NSSortDescriptor *sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"EndDate" ascending:NO];
sortedFinPeriodsDesc = [self.finperiod sortedArrayUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]];
}
IBFinPeriod *lastPeriod;
for (IBFinPeriod *finPeriod in sortedFinPeriodsDesc) {
if ( [finPeriod.EndDate compare:date] == NSOrderedAscending ){ // finPeriod.EndDate < date
lastPeriod = finPeriod;
break;
}
}
return lastPeriod;
}
However, when replacing the first lines (lazy instantiation) in the method by removing the `if clause` and always instantiating and sorting NSArray `sortedFinPeriodsDesc`, the code works fine.
Hence, I have a couple of **questions**:
- What is the error in my code? How does affect lazy instantiation
faulting?
- Would you recommend defining the NSArray `sortedFinPeriodsDesc` as transient attribute and sorting it in `awakeFromFetch` instead?
- What would be the best option in your view?
Thank you very much for your help!

Say I have 2 websites: `example.com` and `example.fr`. They are both served by the same MVC Website in IIS.
Then I have a custom `VirtualPathProvider` that, based on the domain, serves Views from different locations. The Controller is always the same, only the Views are fetched from different locations.
This all works well. The problem comes with ASP.NET View compilation. Suppose both domains have a View with the same name and path (MVC views path for clarity):
example.com/Views/MyController/Index.cshtml
example.fr/Views/MyController/Index.cshtml
This should work well. But the ASP.NET BuildManager (which compiles the Razor code to assemblies), caches the build **based only on the Virtual Path**.
So this means that when I first render a View while visiting `example.com` I get the correct view. But if I then try to render the View in the context of `example.fr`, ASP.NET considers that the view has not been modified (which is true as the Virtual Path is the same) and it will execute the view from cache, hence rendering the incorrect View.
A way to solve it is to maybe have the Views being compiled in different namespaces, based on the domain.
So far I got to `MvcWebRazorHostFactory`, override `CreateHost` method to return a `RazorEngineHost` with the correct namespace. Not sure if it will work because I don't think I have all the needed information at that point (`HttpContext` is one of them)
Anyone has any ideas? Am I missing something obvious here?

I added some JQuery so that I can pre-select the country from some data that I have but when I select the country the ajax is not executed.

inputText = '<?php echo $_SESSION['mysite_country']; ?>';
$("#edit-panes-billing-billing-country option:contains(" + inputText + ")").attr('selected', 'selected');

inputText = '<?php echo $_SESSION['mysite_country']; ?>';
$("#edit-panes-billing-billing-country option:contains(" + inputText + ")").attr('selected', 'selected');
</script>
Anyone know why the Ajax is not executing or how I can get the Ajax to execute?
Now I'm stuck on that and that's step 1. Ideally the provinces should populate and then I'm suppose to select the province too. So the ajax should execute, I'm suppose to know when it's done and then I should select the province.
Thanks for any help. | 0 |

However, if I check the current thread inside the block, it actually is the main thread! The NSLog prints:

Checking the thread dump confirms this.
The fetch should NOT be executed on the main thread, because this does occasionally result in a deadlock with some other running code. So what am I doing wrong here?

I want to use a databound control (say a ListView) with a control that does a postback (a Button) inside the item template. I want the button to perform some action on the data in this item.
The code looks like this:

button.Text = value.ToString();
}
protected void lvTest_ItemCommand(object sender, ListViewCommandEventArgs e)
{
//e.CommandArgument has the new value from the new databinding
}
}
}
The problem is that when the button is pressed e.CommandArgument has the value from the postback databind. If I do not do a databind on postback the event is not raised at all. In most cases this is not a problem because you databind to the same data. However if one user deletes for example item 3 and the second user decides to delete item 3 in the same time the second user will actually delete the fourth item because the items will be reordered on postback. This can be avoided if ViewState is enabled but it should be possible to execute a command without ViewState (after all the one place ViewState should be avoided is databound controls). To add insult to injury I can clearly see that the original (correct) value is posted to the server. It can be retrieved via Request.Form["lvTest$ctrl2$btnTest"] (the key is the UniqueID of the actual control that triggered the postback)
I have tried many ways to apply the command to the correct item like using button click instead of item command, using DataKeys, etc. but I couldn't get the right value for the data item back. It seems like the databound control always uses the row number to get the command argument instead of the values that were actually posted by the browser. The only way I found was to manually look in the Request.Form collection but this does not seem right. Of course I can work around the problem by hooking up a JavaScript function and an AJAX call but I want to know how this issue can be resolved in a pure WebForms way.

To understand why I want to do this, some info on the background may be useful.
Consider a generic procedure that contains a sparse-matrix - vector multiplication, like a Lanczos diagonalization routine. The procedure itself does not use the matrix, only the vector. The only thing the procedure needs to do with the matrix is to pass it, along with the vector, to a matrix-vector multiplication routine. The sparse matrix has to be a derived-type variable with allocatable components.
The way I see it, the procedure does not need to know the data type of the sparse matrix. It just needs to pass it to the matrix-vector multiplication routine, which will then decode it appropriately. What I tried to do was to use the `TRANSFER` intrinsic function to cast the derived-type variable into an allocatable array of bytes, and then transfer it back to the initial derived-type variable. This unfortunately does not work with derived-type variables with allocatable components, see the following two links: <a href="https://groups.google.com/forum/?fromgroups#!topic/comp.lang.fortran/txm5uNMpVtE">Link 1</a>,
<a href="http://gcc.gnu.org/ml/fortran/2011-04/msg00227.html">Link 2</a>
My question is therefore the following, as stated above: is there a reasonable way* to pass derived-type objects with allocatable components to Fortran procedures, without the procedures knowing the type definition?
*Note: I know that I could use customized internal formatted writes to store a derived-type variable into an intrinsic-type array, e.g. a character array. This seems to me extremely weird, but maybe I'm wrong?

for this I am using following code.
echo $this->Js->link('test','/controller/test/', array('before'=>$this->Js->get('#loading')->effect('fadeIn'),'success'=>$this->Js->get('#loading')->effect('fadeOut'),'update'=>'#mydiv'));
It is working fine.
But when I am using this code on view page,which is rendered by ajax, it i not working.
when i check the page source i found that script for this view is not added in the buffered script.
I guess buffered script is created when the page is load.In my case when page is loaded specific content is not loaded so script for this layout is not added in the buffered script.
Please guide me is there any other method by which i can do this or i have to do it by custom jquery or another method.

The issue is that the user will have to login to that website in order to see the information (i.e. like logging into facebook).
I'm trying to develop something like embedding the login page of that external website into my website and then have the user login that way (see below)

My question is how are you able to know if the user has logged in? In the embedded window, I can log in and see the page but my website doesn't know that I have logged in. Is there a way to actively check the URL of the embedded page to see if has changed (i.e. you have logged in)?
I've tried just refreshing the page but the source link for the embed object is the same.

When I run this, it is as though the search bar is disabled. You cannot click on it or open up a keyboard. If I change the vertical position of the search bar from -216 to 0, I can click on it and bring up a keyboard, but I'm unable to type anything.

To do this I have a Tvshow model, a TvshowModelForm and I use the generic class based views CreateTvshowView/UpdateTvshowView to generate the form.
Now comes my problem: lets say a user want's to add a show to the db, e.g. Game of Thrones. If a show by this title already exists, I want to prompt the user for confirmation that this is indeed a different show than the one in the db, and if no similar show exists I want to commit it to the db. How do I best handle this confirmation?
Some of my experiments are shown in the code below, but maybe I am going about this the wrong way. The base of my solution is to include a hidden field 'force', which should be set to 1 if the user gets prompted if he is sure he wants to commit this data, so that I can read out whether this thing is 1 to decide whether the user clicked submit again, thereby telling me that he wants to store it.
I would love to hear what you guy's think on how to solve this.

**Slave** has a method named **Init();**. The thing about **Init()** is, that I need it to be virtual, because it contains user's initialization code, but I also need it to get called automatically when the **Slave** is added to **Master**'s List. But the method must not be callable by the user, it has to be automatic.
The first thing that I tried is an event - create an event **SlaveInitialized** that a **Slave** object could handle in its **OnSlaveInitialized** handler. This wouldn't work though, because there's a lot of **Slave** objects and I have no control over the order in which they get created and need to be initialized.
The second thing that I tried is internal method - **internal Init()** would be called when the object is added to **Master**'s list and all seems okay, until I realized that by doing so I cannot inherit the method in a public class.
So the third thing I did and that worked is this - I created an internal method called **_Init()** that simply calls a **protected virtual Init()**, which solved my problem.

Now I want to ask - do I just have a major strike of being stupid, because I am missing the painfully obvious solution here, or is this the way it's normally done? What is the proper way? I hope I got the point of what I'm asking across, I tried my best to explain the problem.
Thanks for any help | c# | .net | null | null | null | null | open | Hidden calling of a function
===
Let's say I have two objects, **Master** and **Slave**.
**Slave** has a method named **Init();**. The thing about **Init()** is, that I need it to be virtual, because it contains user's initialization code, but I also need it to get called automatically when the **Slave** is added to **Master**'s List. But the method must not be callable by the user, it has to be automatic.
The first thing that I tried is an event - create an event **SlaveInitialized** that a **Slave** object could handle in its **OnSlaveInitialized** handler. This wouldn't work though, because there's a lot of **Slave** objects and I have no control over the order in which they get created and need to be initialized.
The second thing that I tried is internal method - **internal Init()** would be called when the object is added to **Master**'s list and all seems okay, until I realized that by doing so I cannot inherit the method in a public class.

Because I precompiled, all of my assets used during development are now in the public/assets and public/system folders.
I am [aware](http://stackoverflow.com/questions/8356251/rails-3-1-assets-strange-serving-in-development) of two options for accessing my assets during development. The default option seems to be to allow the public/assets files to override my app/assets files. However, if I do this, any CSS changes I make in app/assets is not reflected.
The alternative option is to access ONLY the app/assets folder through:
config.serve_static_assets = false
However, by doing this, I can't see any of my images during development, as they have already been precompiled and moved to public/system
Is there a way to access my CSS/JS files from app/assets, yet still load my images from public/system?
Or am I supposed to do all of my CSS/JS development out of the public/assets folder? Any feedback would be much appreciated. | ruby-on-rails | configuration | asset-pipeline | null | null | null | open | How to access assets during development if precompiling for development

I have one instance that is listening for UDP packets on port 6666, as so:
nc -ul 6666
In another terminal window, I am trying to periodically send a UDP packet from port 6666 (to open the return path on my router. this would be in a script that repeats every 20 seconds to re-open the port)
nc -u -p6666 mypinghost.com 4444
The problem is netcat fails on this ping call with the message:
nc: bind failed: Address already in use
Which implies that the listener having bound to port 6666 is blocking another process from sending from that port, or possibly that netcat is trying to bind to 6666 to listen.
Is this just how netcat is written, or can I tickle it some way to let me send a packet without binding to the port to listen?

$doc->formatOutput = true;
$mainTag = $doc->createElement( "fruits" );

Changes may include both reordering and in-place updates, and I want to animate both, so some rows will need `reloadRowsAtIndexPaths`.
But! `UITableView` appears to be just plain wrong in its handling of row reloads in the presence of moves, if the updated cell shifts position because of the moves. Using the older delete+insert calls, in a way that should be equivalent, works fine.
Here's some code; I apologize for the verbosity but it does compile and run. The meat is in the `doMoves:` method. Exposition below.

}
What the code does: sets up a tiny model (small mutable array); when a button is pushed, it makes a small change to the middle element of the list, and moves the last element to be the first. Then it updates the table view to reflect these changes: reloads the middle row, removes the last row and inserts a new row zero.
This works. In fact, adding logging to `cellForRowAtIndexPath` shows that although I ask for row 2 to be reloaded, the tableview correctly asks for row 3 because of the insert once it's time to actually do the update. Huzzah!
Now comment out the top #ifdef to use the moveRowAtIndexPath call instead.
Now the tableview *removes* row 2, asks for a fresh row *2* (wrong!), and inserts it in the final row-2 position (also wrong!). Net result is that row 1 moved down *two* slots instead of one, and scrolling it offscreen to force a reload shows how it's gone out of sync with the model. I could understand if `moveRowAtIndexPath` changed the tableview's private model in a different order, requiring the use of the "new" instead of "old" index paths in reloads or model fetches, but that's not what's going on. Note that in the second "after" pic, the third and fourth rows are in the opposite order, which should't happen no matter which cell I'm reloading.
![before state][1]
![after one button push, delete-insert style][2]
![after one button push, move-style][3]
My vocabulary has grown colorful cursing Apple. Should I be cursing myself instead? Are row moves just plain incompatible with row reloads in the same updates block (as well as, I suspect, inserts and deletes)? Can anyone enlighten me before I go file the bug report?

===
Following is my code along with the xml file i have 2 table layouts within 2 frame layouts. the 1st table layout is used to set the heading for the table while the 2nd table is used to set the rows dynamically in the 2nd table layout though the heading seems to be fitting perfectly the rows dont align properly below the heading may be i am doing some mistake in setting parameters for the table layout . I am in a fix . Any help will be appreciated. Thank you.

**My first problem** is that I have to use a container (here a Canvas) to hold the path, rectangles and lines.
When i add a **SplineControl** in mycanvas, it's well placed and i can instantly drag my points but when i add another UserControl, it's placed above the previous one and i can't select the first Usercontrol's points.
I don't want to use IsHitTestVisible since I want to select points from the first userControl through the second.
**My Second problem:**
Since I use a Canvas to hold my things in the SplineControl, i can drag points outside of the canvas and still interact with it, and at first sight it was great.
But thinking it again, i'd like to resize my Canvas when i move a point to always have my point in the canvas. but also have my other points positions updated respecting the ratio of mycanvas.
Do you know any control that have this behavior and can replace my Canvas?
Should i use CustomControl instead of UserControl?
May I have to think again my project's conception?

<Line x:Name="line2" Stroke="#dfdfdf" StrokeThickness="1"/>
</Canvas>
</UserControl>
**My first problem** is that I have to use a container (here a Canvas) to hold the path, rectangles and lines.
When i add a **SplineControl** in mycanvas, it's well placed and i can instantly drag my points but when i add another UserControl, it's placed above the previous one and i can't select the first Usercontrol's points.
I don't want to use IsHitTestVisible since I want to select points from the first userControl through the second.
**My Second problem:**
Since I use a Canvas to hold my things in the SplineControl, i can drag points outside of the canvas and still interact with it, and at first sight it was great.
But thinking it again, i'd like to resize my Canvas when i move a point to always have my point in the canvas. but also have my other points positions updated respecting the ratio of mycanvas.
Do you know any control that have this behavior and can replace my Canvas?
Should i use CustomControl instead of UserControl?
May I have to think again my project's conception?

Move images between grids based on selected rows (aka just getting selected rows and/or handling onclick events)
I actually got pretty far along doing this with jqgrid treegrid, based mostly on this example: http://stackoverflow.com/questions/6788727/jqgrid-tree-grid-with-local-data , however I've been getting javascript errors when attempting to refresh the grids after modifying their data. Upon debugging the code there were some obvious errors accompanied by comments such as //??? and some //TODO statements so I believe that jqgrid treegrid isn't completely funcitonal(at least for local data) Some of their documentation indicate that this is the case too. All the jquery references where up to date.

The docs on the linked page describe what's necessary to get a lighthttpd server running quickly, minimal configuration and all.
I've read the cherryd usage, glossed over a Packt book and the online docs, and have read a few posts here about static files and CherryPy, but have yet to find something similar. I've been able to piece together the following config file:
[global]
server.socket_host: "127.0.0.1"
server.socket_port: 8000
log.accessfile = '/Users/chb/code/app/test/log/cherrypy.access.log'

[/]

Visiting 127.0.0.1:8000 gets me a 404. When I `tail` the error log after running `cherryd -c /path/to/cherryd.cfg`, though, nothing comes up apart from the standard startup info.
Aside: I'm aware of the possibility that I might have chosen poorly. I just wanted to start up a server, point it at a directory and have it serve static files. I thought `cherryd` would be good/easy for that.

I don't like this general approach because this shoves all errors concerning process invocation into the exit code of the child process and the `stdout/stderr` (which I need as binary streams in my application!).

I can't seem to get it to work:
public TValue MaxValue(Func<TValue,TValue> func)

return this.valueSet.Max<TValue>(func);
