my problem is, if I order the reading of the database (orderby) the datagrid will not be changed if I add a new row. if i do not order the reading it works.
so addition infos:
my database looks like this
Table Konto
KontoID
KontoName
Table Buchung
KontoID
BuchungsID
Name
BuchDate
after the Konto is loaded it will load all related Buchungen
_entityKontoView = new CollectionViewSource();
_entityBuchungView = new CollectionViewSource();
// Loads the Konto
_entityKontoView.Source = _database.Konto;
_entityKontoView.View.CurrentChanged += (x, y) =>
{
_entityBuchungView.Source = ((Konto)_entityKontoView.View.CurrentItem).Buchung
//.OrderBy(date => date.BuchDate)
//.ThenBy(buchnr => buchnr.BuchungsID)
;
};
_entityKontoView.View.Refresh();
when i do now an `OrderBy` the datagrid will not be update after new inserted Row
i open the the database entity as follow:
public static databaseEntities _database = new databaseEntities();
my XAML binding on DataGrid:
ItemsSource="{Binding EntityBuchungsView.View}"
and my columns binding ;
Binding="{Binding Name}"
as far i used `_database.Buchung.AddObject(test);` and then `_database.SaveChanges();` and my DataGrid got updated.
what do i false?

We work with maps a lot and, to simplify, represent a map as a std::vector< std::vector<int> >. The OpenCL API takes raw c-style pointers as arguments, for example int* in the case above.
My questions:
- Are there implementation guarantees in the stl that vector is, internally, consecutive in memory?
- Can I safely cast a std::vector<int> to int* and expect that to work?
- In the case of a vector of vectors, can I still assume this holds true? I would expect the vector to hold other state data, or alignment issues, or maybe something else...
- What is the best way to approach this? Write a custom 2d data structure that holds an internal, contiguous-in-memory buffer and work with that? I'd have to copy to/from vectors a lot...

1) Explain why the single quotes around username do not have to be escaped?
2) Where there is a "dummies" write up on escaping characters so I could try to decipher the second example.

I like the ```joins{ roleables(my{self}) }``` but I just cannot seem to get the rest of the SQL restructured :(
I've tried with a subquery like
Roleable.permissions.select{ group_concat( authorization ) }.where{ (roleable_id==1) & (roleable_type=='User') }
and that does handle the subquery - except for the _id and the _type which will be the id of each selected row and the class.to_s of the selected row instance (or rather the class of the singleton doing the call in the first place - like User.joins... etc.
- and then there's the business with the role_id in () - which translates into
where{ roleables.role_id >> current_user.roles }
but how do I amass this into the rest
Arrgghhh, what a mess :(
So - why don't I just fire the SQL away? Well, I'd like to, but the result has to be compatible with Kamanari - 'cause after this comes pagination - so, that's why <:)

I'm loading login screen with calling UIModalPresentationFormSheet from firstviewcontroller. once the user clicks on the login button it should make a server call and should send the response. I'm calling that server call method like this in second view controller
RatingsAndEquitiesService *REService = [[RatingsAndEquitiesService alloc] initWithTarget:self action:@selector(connectionSuccess:) failAction:@selector(connectionFailure:)];
In server call class I'm returning the received data like this
[target performSelectorOnMainThread:action withObject:data waitUntilDone:YES];
After the server call either connectionSuccess/connectionFailure is calling respectively in the second view controller. But here my issue is I want to reload the table view data which is located in first view controller after server call has been done. In first view controller i created one method like reloadData and I'm calling this method from connectionSuccess method of first view controller. But my [tableview reloaddata] is not calling which is in first view controller. How to solve this problem? Can some one please suggest me.

In my dialog window I try to update the `ProgressBar` using syncExec or asyncExec methods with values within the Object. And the Object is unlocked just after calling the methods.
I know that those methods are waiting for the most "suitable" occasion to run there runnables. However what I do not seem to understand is, why those methods are not executed if there is nothing running while they are called?

After the login or in case of any input errors I want the ViewController to go back to the view where the user initiated the login process.

Detail: I have a table that is 800GB. A few months ago I went to apply an index on it and the transaction log filled up (for obvious reasons - was dumb of me to even attempt it). Instead I had to create the table over again, apply the index I wanted and then copy the records over.
Now we are going to be setting up partitions on this table. I'm wondering if I remove the clustered index and apply the new clustered index on a partitioning layout if it will still fill up the transaction log (assume I have 10 million rows per partition)? Or will the tlog not fill up because the indexes would also be partitioned which would allow the SQL server to finish an index faster and be able to checkpoint?
Does anybody have any idea? Otherwise I can just re-create the table again and apply the partition stuff to it and re-fill it but obviously that is much more involved.

I have two main use cases:
No headers sent
---------------
Fix here is simple, just throw http 500 errors without changing url.
Partial page error
------------------
In this case, some html & http headers were already sent to the client. In order to prevent a partly broken page from displaying, I output javascript that causes a redirect completely to an error page url, /error.html . This is to avoid displaying part of a normal page and part of an error page, and make it clear that the resulting html is not optimal even if the section that the error message ends up being displayed in is currently hidden, by moving to a dedicated error page.
Unfortunately, when hitting "back" from the dedicated error page, the original erroring page gets cached, and the javascript redirect is performed again, even if the error has been fixed in the meantime.
For example, if there is an error after headers are sent in index.php, javascript will output that redirects a user to /error.html. Once there, they can return to the homepage (which should be fine), or hit back. When they hit back, they may get a cached page that re-redirects them to error.html.
index.php > error.html (hit back) cached index.php > error.html
What is the ideal way to avoid this situation?
In the code below, I try to add #error hash in the url to redirect only the first time, and on subsequent visits to a broken partial page start a 60 second refresh attempt cycle. Unfortunately, when I set the #error hash and the redirect, then hit back, it goes to index.php, not index.php#error, so the cached infinite loop occurs.
How do I gracefully handle partial-page 500 errors?
Here is the code in my php custom error handler, which causes the above listed behavior:
function showErrorPage() {
if (headers_sent()) {
// This is complicated due to the infastructure tending to have already sent headers, ...
// ...requiring a tuned javascript redirection in many instances.
// Output the following as html.
?>
<meta http-equiv="Cache-control" content="no-cache, no-store">
<script type='text/javascript'>
var currentHash = location.hash;
// UNFORTUNATELY, HERE THE HASH NEVER SHOWS AS SET!
if(!currentHash){ // If hash wasn't already set...
location.hash = '#error';
location.href = 'error.html'; // Redirect once.
} else { // Otherwise, the hash was already set, they were redirected once but came back.
// So just display this page for a time but refresh on a slow schedule.
setTimeout(function(){
location.reload(true); // Non-caching refresh.
}, 60*1000); // Reload after 1 min delay
}
</script>
<?php
} else {
// No headers sent, so set the right headers
header("HTTP/1.1 500 Internal Server Error");
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
}
// Regardless, include the visible error output and throw exit with error.
include(WEB_ROOT.'error.html');
exit(1);

My task is to create some generic scheduler for different services in the webapp that can be used later in development. For example we have some available tasks that user can schedule whenever he wants.
I didn't want to reinvent the wheel and found the Quartz.Net library that can be used to create the scheduler.
I know that it's not a good idea to host scheduling inside webapp cause webserver can recycle the application pools, etc, so i decided to use it inside a Windows Service and then using Quartz.NET remoting feature to trigger tasks inside my webapp.
But i've found some issues with that. Correct me if I'm wrong, but when i tried to use the Quartz.NET remoting it runs the job inside the Windows Service process, it means that it needs to know about all types inside my webapp, so all the assemblies of the webapp should be referenced by it, and i need to have another config file for database, etc. So in case I write new job class, i can't easily schedule it, i need to stop the service and renew the library for it, so it's not very generic approach.
I can't find any info that Quartz.NET can run jobs only based on it's interface.
So I came up with idea to write my own scheduler that will be hosted in the Windows Service, and will have some IJob interface that will be implemented in the webapp. I will also use .Net remoting using IPC channel.
So the webapp will be like .Net Remoting Server, and when i want to add some new job and then schedule it, i will just have to write new job that implements IJob interface.
I will register it as
IpcChannel channel = new IpcChannel("CurrentIPC");
ChannelServices.RegisterChannel(channel);
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(SimpleJob), "SimpleJob", WellKnownObjectMode.SingleCall);
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(ComplexObject), "ComplexObject", WellKnownObjectMode.SingleCall);
in this case i will have two Job types registered. Then when scheduling the job i will pass the name of the class and on the Windows Service side that will stand for client (executing objects on the webapp side) i will just bind the passed name of the class with IJob like this:
Dictionary<string, IJob> jobs = new Dictionary<string, IJob>();
void AddJob(string name)
{
IJob obj = (IJob)Activator.GetObject(typeof(IJob), string.Format("ipc://CurrentIPC/{0}", name));
jobs.Add(name, obj);
}
So now i don't need to bother about references to my app and other stuff, the scheduler will do it's job without knowing anything, just IJob interface and executing tasks on the webapp side.
If i'm wrong or it's too complex and there are some other simpler methods of doing this, or there are some pitfalls that i'm not aware of, can you help me with that?
Thank you.
P.S.
Also there was an idea to have separate scheduler that will run the web app methods directly by executing a link to specified service in the web app, for example "http://localhost:3030/Request/12" and that's all, but in my web app you should be authorized to execute such request and again we have issues we need to resolve, and we will have additional load to the webserver with such requests in case of thousands of scheduling tasks. | c# | .net | asp.net-mvc | quartz.net | .net-remoting | null | open | MVC3 webapp task scheduling with Quartz.NET

Developers in X.X.X.X/24 need to do HTTP requests to the two different versions of our website.
They used to do it changing /etc/hosts accordingly.
Now we have transparent squid in the middle that resolves DNS before HTTP-requesting, so all requests end up in the public, production version of our website.
I do not know how squid internals that allow transparent proxying work, but is there a workaround that allows only developers' machines to control locally on their machines where their requests will go?
Something like "do not DNS-query if for these, say X.X.X.X/29, machines"?

I've got a .xib, which was created by XCode when I created a new `UIViewController` subclass. It has quite a few elements, including some `UIButton`s, a bunch of `UILabel`s, a small `UIView` with some other views inside it, and a `UIImageView` containing a mostly-transparent image.
In `viewDidLoad`, I set the background color of the main view to a color using a pattern image.
When I display this view controller in the simulator or on my iPhone 4 (both running iOS 5.1), everything goes smoothly; the patterned background displays, the labels show up in the proper font, the transparent image appears, and so on.
When I test on my old iPod Touch 2G running 4.3, however, the view controller loads, the `UIButton`s, the `UIImageView` and the small `UIView` all display correctly... but the `UILabel`s don't show up at all, and the patterned background color doesn't display either.
The only even vaguely unusual thing I'm doing when the view gets presented is this, which makes it size properly in a popover:
- (void) viewWillAppear:(BOOL)animated {
CGSize size = CGSizeMake(320, 480); // size of view in popover
self.contentSizeForViewInPopover = size;
[super viewWillAppear:animated];

Has anyone else encountered this? | ios | xcode | uiview | ios4 | uiviewcontroller | null | open | .xib not loading properly on iPod Touch 2G (ios4.3), fine on later devices?
===
I'm running into a tricky glitch.
I've got a .xib, which was created by XCode when I created a new `UIViewController` subclass. It has quite a few elements, including some `UIButton`s, a bunch of `UILabel`s, a small `UIView` with some other views inside it, and a `UIImageView` containing a mostly-transparent image.
In `viewDidLoad`, I set the background color of the main view to a color using a pattern image.
When I display this view controller in the simulator or on my iPhone 4 (both running iOS 5.1), everything goes smoothly; the patterned background displays, the labels show up in the proper font, the transparent image appears, and so on.
When I test on my old iPod Touch 2G running 4.3, however, the view controller loads, the `UIButton`s, the `UIImageView` and the small `UIView` all display correctly... but the `UILabel`s don't show up at all, and the patterned background color doesn't display either.
The only even vaguely unusual thing I'm doing when the view gets presented is this, which makes it size properly in a popover:
- (void) viewWillAppear:(BOOL)animated {
CGSize size = CGSizeMake(320, 480); // size of view in popover
self.contentSizeForViewInPopover = size;
[super viewWillAppear:animated];
}
I really can't think of anything else that might be the problem. I've cleaned, rebuilt, all that stuff. Still no dice.

My challenge is how to encode the data in Objective-C in a way that I can decode on the Rails side. I'm using the [example in this SO question][1] as the method to encrypt the data, and the example code shows what the encrypted data would look like this:
printf("%s\n", [[plain description] UTF8String]);
which creates output that looks like:
> <3fe47b63 bd9a84ab 30dfb1a4 e409b60f>
My challenge is that I need to find a way to get this across the wire to the Rails application in a way that I can decode for use with OpenSSL code like:
def decrypt(data)
cipher = OpenSSL::Cipher::Cipher.new('aes-256-cbc')
cipher.decrypt
cipher.key = cipher_key
cipher.iv = cipher_iv
decrypted_data = cipher.update(data)
decrypted_data << cipher.final
end
I'm thinking that Base64 encoding may be the best way to go as this data will end up in an HTTP header in JSON requests. It seems like I could use Base64.decode64 to decode the data on the Ruby side and pass it as the data to decrypt, but I'm hoping someone can guide me on whether this really is the best way to do it and, regardless of the encoding, how to turn a pointer to an NSData object like this:
NSData *cipher = [plain AES256EncryptWithKey:key];
into that encoded value to get it to the Rails app. Thanks!

The web-app allows users to login and signup using external services (ie. Facebook and Twitter). We need to allow the same also on the mobile app. The question is: how can we do that?
The Pinterest mobile app is able to manage the situation (see attached image). What is the flow that's been used here?
Do they behave like a classical OAuth-powered app (the mobile app acting as OAuth client directly with the Facebook API?). If so, then how can the mobile app be authenticated with the Pinterest server? Is it passing the Facebook OAuth access token as credentials?

I'm developing a native mobile app for a custom, web-based social network app. We're building a REST API to communicate with the web server, and we've chosen OAuth2 as the authentication method (the `grant_type=password` flow).
The web-app allows users to login and signup using external services (ie. Facebook and Twitter). We need to allow the same also on the mobile app. The question is: how can we do that?
The Pinterest mobile app is able to manage the situation (see attached image). What is the flow that's been used here?
Do they behave like a classical OAuth-powered app (the mobile app acting as OAuth client directly with the Facebook API?). If so, then how can the mobile app be authenticated with the Pinterest server? Is it passing the Facebook OAuth access token as credentials?

But I am not confident enough to say do, so I would like to seek your advise.
It'd be a bit difficult for me to describe the case in plain text, so I prepared a snippet:
http://jsfiddle.net/2eQXa/1/
Visiting the site you should see a yellow background with red border. This is not a background of the <body> tag but a <div> with id "backdrop" which has 100% with and height. By default it is assigned to a class "backdrop-no-problem". Also there is a horizontal list with some images. The list is surrounded by a green border. Inside the list is the wikipedia image wrapped with a dotted red border.
I am testing the page using 3 devices:
1. Chrome 21 on Windows 7
2. Mobile safari on the first generation iPad (running iOS4, I'll call it iPad1)
3. Mobile safari on the "new" iPad (running iOS5, I'll call it iPad3)
Try clicking "right" or "left" to scroll the list. Pretty good.
To reproduce the my problem, first click on "Issue #1". This will change the backdrop div from "position:absolute" to "position:fixed". Then click "Issue #2". This will add "-webkit-backface-visibility: hidden;" to the element. The reason of this is to ensure smooth animation on the iPad which is not included in this snippet.
Now click "left/right" to scroll the list. You should see a strange behavior in all three browsers:
The green div is scrolling properly and smoothly, but not its child elements. The child elements simply "out-sync" with the position of the scrolling parent. The movement is not only look laggy, it sometimes even stuck. And the child elements will stop at a wrong position when the scrolling animation finishes. You have to move your mouse over the picture (or tap on it in a tablet) to trigger an update to have the element re-draw at the right place. Even chrome experience this weirdness makes me feel that it is a webkit issue.
In fact things gone worse in iPad3. In iPad3 you don't need to add "-webkit-backface-visibility: hidden;" (Issue #2) to see this weird behavior. Just add "position:fixed" (Issue #1) will do. The strange thing is that this doesn't happen when you view the snippet in jsFiddle. In case you are interested I have put the source in a single file at pastebin:
http://pastebin.com/i4ARX4mD
When writing this question I saw quite a number of questions regarding backface visibility. I've checked some but none of them matches my problem.
Ideas or suggestions are welcome. Thanks! | css | ipad | google-chrome | webkit | mobile-safari | null | open | Webkit rendering quirks for element with "position:fixed" and "-webkit-backface-visibility: hidden;"?

Using this three information i am successfully connecting to VPN network if i am configuring manually from device. But i want to do this programmatically.Here is the class file which is used to connect to VPN network.[ToyVpnClient.java][2] and [ToyVpnService.java][3]
Any help will be appreciated.<br>Thanks

However, I have been searching for 3 days now, and have not found an answer...
My problem is, I cannot for the life of me figure out how to pull the contents of a file(any file). From reading the docs I've discovered that my returned file resource object is supposed to have a property named "downloadUrl", and from this I should be able to access the file contents.
None of the file resource objects that are returned to me(via gapi.client.request) have this field/property. Below is the function I am using to get a file.
Can someone please help point me in the right direction? I have to have this demo done by Monday and I've been stuck on this for 2 days....
Here is the code for my get function :
Client.getFileContent = function getFileContent() {
gapi.client.load('drive', 'v2', function() {
var request = gapi.client.request({
path : '/drive/v2/files/1QmaofXyVqnw6ODXHE5KWlUTcWbA9KkLyb-lBdh_FLUs',
method : 'GET',
params : {
projection: "FULL"
}
});
request.execute(function(response) {
console.log(response);
});
});

I have [found][3] [many][4] [examples][5] on StackOverflow on how to split a PDF by page with C#. But how can I do the latter? How can I split a PDF file by a maximum file size using C#?
For example, say I have a PDF file that is 70 pages and 40 MB. Instead of splitting into 7 files of 10 pages each, how can I split the file into around 5 files that are no greater than 10 MB each using C#?
So far, the best method I have seen was in [Using itextsharp to split a pdf into smaller pdf's based on size][6] where [Cyfer13][7] used [iTextSharp][8] to split the file by page and then group those page files by size. But is a more direct way to accomplish this without having to first split by page?

Is it possible to have the cross hairs follow the line on the series? So the horizontal line would fix to the y position of the line and not following the mouse. I see you can get the x/y position of each data point but not of the lines inbetween points.

I'm using an iframe which works fine in all browsers except Firefox (it forces download). Sometimes FF can do it, sometimes not, depending on whatever plugin is installed but I have no control over the FF config of my users.
I've tried using Google Docs to embed the PDF which works fine except the lines of text that have PraxisCom-Bold.ttf as font - these don't display in Google Docs (even when I view it in Google Docs non embedded). Zoho viewer displays these lines but not in the proper font.
Before I start trying to convert my PDF to a JPG - are there any other options at all to reliably display a PDF in Firefox? | firefox | pdf | null | null | null | null | open | Embedding PDF in Firefox
