1,061,785 | So, this may sound stupid but I don't really get it. When I visited <http://www.themidnightcoders.com> and download WebOrb for .NET. After I finished product setup progress, I realize that the product that I just downloaded and setup in my machine was "Enterprise Edition in Development mode"
Because when I go into the product web console page. It tell me that, it's in development mode and limit for on 5 IP Addresses. When I return to download-page of WebOrb site I only found one product for download and it's the one that I just downloaded.
So I want to use WebOrb for .NET Community Edition but I have not found it yet.
May you please tell me the solution of this problem?

21,541,839 | I am new bie to hibernate and i am facing one issue.
I have fetched the record from database and displayed the values on Jsp form.
I want to update some of the values i have displayed
I made the ID of the entity hidden form field.
When i click on submit the values which are not on form are set to be null.
Everytime i have to update the record i have to manually set all the values again to the object and then save
Example
I have user entity having the following fields
Id
firstName
lastName
dateUpdated
dateCreated
In my jsp i have only two fields
firstName
lastName
and on hidden form field
Id
In my controller i am creating new obj of User and setting these three values
I am updating my record using merge method.
on merging
DateCreated and dateUpdated are getting null!
How can i achieve it without fetching the record and setting the modified value and then saving it

] | Strings in Java are *immutable*. Every time you use the concatenation operator (`+`) you're actually creating a new `String` object.
Because you're starting with your `String` being `null` ... the conversion during the concatenation results in the word "null" in the result (this is specified in the JLS when using string concatenation).
You *could* simply start with an empty `String` (e.g. `String webresponse = ""`) but that's still really inefficient due to the aforementioned immutability.
You want to use a `StringBuilder`:
```
String line;
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null) {
sb.append(line);
}
```
**Edit:**
I just noticed: *" that is generally a bad approach as I just initialized the var webresponse when it's not supposed to be (and can't check for null later)!"*
`String` does provide a `.isEmpty()` method ... so I don't know what advantage `null` gives you, but you could simply check the length of the `StringBuilder`
```
String webresponse = null;
if (sb.length() > 0)
{
webresponse = sb.toString();
}
``` | In java you have to give default value to local variables. Local variables are those variables which are defined within methods. So you need to initialize your local variable with default value. You have defined with Null. So when you concatenate with this. It will add "Null" + your other values. To avoid this you can initalize your local variable with empty string e.q String ab="";
Second you are using String to concatenation is wrong. You are creating lots of String object. Instead you can use StringBuilder or StringBuffer. Right approach is to use StringBuilder if you are not worry about synchronization. |

] | You can't. If you lost your private key (part of the p12) you will need to create a profile certificate. | **You have to create new distribution certificates and provisioning profile**
Go to developer portal,
Revoke your current distribution certificate *(whose p12/private key lost)* It won't affect existing live app, Now wait a few seconds and refresh the page and you should see a button "Request Certificate". You'll have to follow the Certificate Signing Request instructions again and upload the .csr file. Create new certificate & download it and install in your Keychain Access app on your Mac. Export the .p12 from Keychain. Your Private key is ready.
Now, delete the existing distribution provisioning profile with old certs,
You'll have to create a new provisioning profile for the App, using the new certificate.
Uplaod the **new p12 and distribution provisioning profile** to phonegap console. Create IPA and Submit to iTunesConnect.

```
class ChildActor extends Actor {
val tagger = IntializeTagger(...) // this takes a few seconds to complete

``` | I think what you might be looking for is the combo of `Stash` and `become`. The idea will be that the child actor will set it's initial state to uninitialized, and while in this state, it will stash all incoming messages until it is fully initialized. When it's fully initialized, you can unstash all of the messages before swapping behavior over to the initialized state. A simple example is as follows:
```
class ChildActor2 extends Actor with Stash{
import context._
var dep:SlowDependency = _
override def preStart = {
val me = context.self
Future{
dep = new SlowDependency
me ! "done"
}
}
def uninitialized:Receive = {
case "done" =>
unstashAll
become(initialized)
case other => stash()
}
def initialized:Receive = {
case "a" => println("received the 'a' message")
case "b" => println("received the 'b' message")
}
def receive = uninitialized
}
```
Notice in the `preStart` that I'm doing my initialization asynchronously, so as to not halt the startup of the actor. Now this is a bit ugly, with closing over the mutable `dep` var. You could certainly handle it by instead sending a message to another actor that handles instantiation of the slow dependency and sends it back to this actor. Upon receiving the dependency, it will then call `become` for the `initialized` state.
Now there is one caveat with `Stash` and I'll paste it in right from the Akka docs:
```
Please note that the Stash can only be used together with actors that
have a deque-based mailbox. For this, configure the mailbox-type of the
dispatcher to be a deque-based mailbox, such as
akka.dispatch.UnboundedDequeBasedMailbox (see Dispatchers (Scala)).
```
Now if this does not suite you, you can try a more `DI` type approach and let the slow dependency be injected into the child actor via it's constructor. So you would define the child actor like so:
```
class ChildActor(dep:SlowDependency) extends Actor{
...
}
```
Then when starting up this actor, you would do it as follows:
```
context.actorOf(new Props().withCreator(new ChildActor(slowDep)), name = "child-actor")

19,985,610 | I've got a String that I need to cycle through and create every possible substring. For example, if I had "HelloWorld", "rld" should be one of the possibilities. The String method, substring(int i, int k) is exclusive of k, so if
```
|H|e|l|l|o|W|o|r|l|d|
0 1 2 3 4 5 6 7 8 9
```
then
substring(7,9) returns "rl"
How would I work around this and get it to work inclusively? I understand why a substring shouldn't be able to equal the String it was created from, but in this case it would be very helpful to me in this case.
Example from Codingbat: <http://codingbat.com/prob/p137918>
What I was able to come up with:
```

String sub;

return str;
for (int i = 0; i < str.length() - 1; i++) {
for (int k = i + 1; k < str.length(); k++) {

] | It seems like you may have some in the tables MySQL uses to store database definitions.
Your best option is to let MySQL try an recover.
Check disk space and ensure you have enough free space for MySQL to work normally - this is a common cause of this problem. An unexpected shutdown may also have been the cause.
Once it completes you may want to do a check and repair to make sure all is operational - be away that this may take some time as well.
```
mysqlcheck -u root -p --auto-repair --check --optimize --all-databases
```
Sometimes the repair may get stuck in a an internal lock, and never seems to stop, if your database is under 1GB and it's taken longer then 30 minutes, kill the mysql server process and try and restart it.
If that still doesn't help, start the server in safe mode and try and take a backup, safe mode can be started with;
```
sudo mysqld_safe

35,248,973 | I'm trying to code a program where I can:
1. Load a file
2. Input a start and beginning offset addresses where to scan data from
3. Scan that offset range in search of specific sequence of bytes (such as "05805A6C")
4. Retrieve the offset of every match and write them to a .txt file
i66.tinypic.com/2zelef5.png
As the picture shows I need to search the file for "05805A6C" and then print to a .txt file the offset "0x21F0".
I'm using Java Swing for this. So far I've been able to load the file as a Byte array[]. But I haven't found a way how to search for the specific sequence of bytes, nor setting that search between a range of offsets.
This is my code that opens and reads the file into byte array[]
```
public class Read {
static public byte[] readBytesFromFile () {
try {
JFileChooser chooser = new JFileChooser();
int returnVal = chooser.showOpenDialog(null);
if (returnVal == JFileChooser.APPROVE_OPTION) {
FileInputStream input = new FileInputStream(chooser.getSelectedFile());
byte[] data = new byte[input.available()];
input.read(data);
input.close();
return data;
}
return null;
}
catch (IOException e) {
System.out.println("Unable to read bytes: " + e.getMessage());
return null;
}
}
}
```
And my code where I try to search among the bytes.
```
byte[] model = Read.readBytesFromFile();
String x = new String(model);
boolean found = false;
for (int i = 0; i < model.length; i++) {
if(x.contains("05805A6C")){
found = true;
}
}
if(found == true){
System.out.println("Yes");
}else{
System.out.println("No");
}

] | Here's a bomb-proof1 way to search for a sequence of bytes in a byte array:
```
public boolean find(byte[] buffer, byte[] key) {
for (int i = 0; i <= buffer.length - key.length; i++) {
int j = 0;
while (j < key.length && buffer[i + j] == key[j]) {
j++;
}
if (j == key.length) {
return true;
}
}
return false;
}
```
There are more efficient ways to do this for large-scale searching; e.g. using the Boyer-Moore algorithm. However:
* converting the byte array a String and using Java string search is NOT more efficient, and it is potentially fragile depending on what encoding you use when converting the bytes to a string.
* converting the byte array to a hexadecimal encoded String is even less efficient ... and memory hungry ... though not fragile if you have enough memory. (You may need up to 5 times the memory as the file size while doing the conversion ...)
---
1 - bomb-proof, modulo any bugs :-) | **EDIT** It seems the charset from system to system is different so you may get different results so I approach it with another method:
```
String x = HexBin.encode(model);
String b = new String("058a5a6c");
int index = 0;
while((index = x.indexOf(b,index)) != -1 )
{
System.out.println("0x"+Integer.toHexString(index/2));
index = index + 2;
}

] | Your code overflows the buffers for `old` and `new` because they do not contain enough space for a 1 character string. In C strings needs to be null terminated, so a `char` array must always be one element longer than the maximum number of characters it must contain. For example your `word` array can only hold a 49 character string, since the 50th element must be the null.
So `old` and `new` must both be `char[2]` arrays. | Your loops are unnecessary and incorrect. You can print the values directly without specifying the index. In your post you're trying to loop through each index and print a character at a time. Here's what you should do:
```
int main (){
int i, j, k;
char word[50], old[2], new[2];
printf("Enter a word: ");
gets(word);
printf("Enter desired letter to substitute: ");
gets(old);
printf("Enter the new letter: ");
gets (new);
printf("%s\n", word);
printf("%s\n", old);
printf("%s\n", new);

In the 'SearchByTitle' function, it is correctly picking up on if the target is in the list, as well as printing it out successfully, however, it will only print out the actual target word. Is there a way to get it to print out the entire line?

Also, when SortingByPrice, it will only return the closest price less than the target, rather than all that are less.

This sentence is perfectly idiomatic. *Le lycée* is likely here the high-school she studies in, work at, or just refer too but might also be high-school in general compared to something else.
Note also that *j'écoute la musique* means "I listen to the music" so to properly translate "I listen to music", you would use:

You wouldn't say in French "Elle aime le lycée."; it is not idiomatic; what you'd say instead would be something like "Elle aime la vie de lycée.", or "Elle aime aller à l'école au lycée.". That is a generic use of "le".
Here, you are taking "high school" as you do "school" meaning (uncountable, used without *the* or *a*) the process of learning in a school, the time during your life when you go to school. You say "She likes high school." as you say "She likes school.".
In French you render "She likes school." by "Elle aime aller à l'école." or "Elle aime l'école."; the two possibilities do not exist for "lycée", though.

If you are talking about a particular place in which there is such a school besides other things such as a skating ring, a Church and a cinema for instance then you can use "le" according to the second way of using this definite article, that is in a specific mode, and say "Elle aime le lycée.", but then you do not translate "She likes high school." but "She likes **the** high school."
**II**
It can be both; if you take "I listen to music." as meaning "I listen to *some* music." you will translate as such:
* "J'écoute **de** la musique.".
If you take "music" as the noun "music" used generically, then you say "la musique";
* J'écoute la musique.

*Explications supplémentaires*
« Aimer l'école », comme je conçois cette expression, c'est aimer les études en général dans le cadre d'une institution d'enseignement collectif, et c'est un peu plus, c'est aussi aimer l'ambiance dans laquelle ces études se font. Cela ne s'applique peut-être pas trop au niveau universitaire, mais alors on peut se restreindre à un terme, qui même si plus général n'est plus associé à l'idée d'ambiance, laquelle devient comparativement beaucoup moins importante dans ce cadre-là ; ce terme est tout simplement « aimer les études ».
Il me semble que c'est quelque chose de similaire pour à peu près tout le monde, les uns ayant possiblement moins d'enthousiasme pour les études que pour l'ambiance et vice versa pour les autres. Ceci dit, il reste le sens plus terre à terre dans lequel l'école n'est plus qu'un établissement particulier, le site sur lequel se trouve ses bâtiments, les bâtiments eux-mêmes, leur architecture, etc.
Dans ce dernier sens l'expression se trouve beaucoup plus rarement. Il existe même d'autres sens de cette locution, et concernant ceux-là « école » peut avoir des sens divers, tels que « système de pensée » ; ils sont encore plus rares, et on se limite aux deux premiers.
En dépit de la possibilité de ces deux sens, il n'existe pas de doute dans l'esprit de l'utilisateur du français qui est assez familier avec cette langue, lorsqu'il entend cette expression dans un contexte faiblement précisé ou même pas précisé du tout ; la raison de cela est assez claire : le premier sens est presque toujours celui dont il s'agit ;
on a donc en cette expression virtuellement une expression figée. Il n'en est plus de même dès lors que l'on remplace « école » par « lycée » ou un terme semblable ; quand cela arrive, d'emblée, on n'est pas sûr de ce dont il s'agit. La raison de ce fait est encore assez évidente, et c'est qu'il nexiste pas un usage bien établi. Voilà donc ce que je reproche à cet usage naissant.

] | French nouns almost always require an article in French so that would be:
>
> *Elle aime **le** lycée.*
>
>
>
This sentence is perfectly idiomatic. *Le lycée* is likely here the high-school she studies in, work at, or just refer too but might also be high-school in general compared to something else.
Note also that *j'écoute la musique* means "I listen to the music" so to properly translate "I listen to music", you would use:
>
> *J'écoute **de la** musique*.
>
>
>
Both *elle aime lycée* and *j'écoute musique* are always ungrammatical in French, a little like would be "I listen music".
Note however that there are some cases, both in spoken and written French, where an abstract noun like *musique* might not take an article.
e.g.:
>
> *Musique, maestro !* Very common expression used to tell an orchestra or a band to start playing.
>
>
>
>
> *L’histoire des relations entre musique et littérature est tumultueuse.* [*Fabula*](https://www.fabula.org/lht/8/reibel.html), 2011
>

> | I understand in English, the language learner may ask when to use an article, when to use "the", etc. When "the" is used, it answers the question "which one?".
In French, the question is not so much when **to use** articles, rather when **not to use** them. As I would be tempted to say **always**.
However, there are cases where you would not use them. Refer to the use of "article zéro" (Ø) in French to learn more.
Here are examples I found in this [thread](https://www.etudes-litteraires.com/forum/topic24656-article-zero.html):
>
> * Pierre qui roule n'amasse pas mousse. (proverbes)
> * tambour battant, chemin faisant (archaïsmes, locutions figées)
> * Mère décédée. Enterrement demain. (télégrammes)
> * Il viendra mardi. (ce mardi-là )
> * Maison à vendre. Sucre en poudre. (sur pancartes, étiquettes)
> * Venez, jeune homme ! (apostrophe)
> * Hommes, femmes, enfants, tout le monde était là. (énumération)
> * Le métier de prof. Pierre est avocat. Le lion, roi des animaux. (appositions, attributs)
> * Arbre est un nom masculin. (= "Le mot arbre" )
> * avoir faim, demander pardon, donner envie, faire fortune, perdre pied,
> prendre feu, rendre service, etc. (locutions verbales).
> * avec joie, sans crainte, sur place, etc. (locutions adverbiales)
>
>
>
Some examples: "faire cas" de qqch. Or "j'ai eu vent de ...". "Je vous souhaite bonheur et prospérité". Etc.
As to the use of articles in English, they do map to something in French.
For example:
* Je mange **du** fromage\*\* => I eat **Ø** cheese. (Recall that we don't say de le, instead it becomes du. If the noun is feminin, use de la)
* Je mange le fromage => I eat the piece of cheese (I don't think you'd say the cheese (?) )
* Je mange un fromage => I eat a piece of cheese
* J'écoute de la musique => I'm listening to music
* J'écoute la musique => I'm listening to the music (you brought me)
But there are cases where it doesn't change:
* Le chômage est de 16% et continue de croître. => Unemployment is 16% and keeps rising.
So, just tell yourself that there are always articles. The rare cases where you don't use them, you'll learn them as you go. And retain that **j'écoute de la musique** is **I'm listening to music** and **j'écoute la musique** is **I'm listening to the music**.
edit: By the way, I absolutely don't see what's wrong with saying "elle aime le lycée". |

(Declare a signal in a process.)
How would you resolve visibility?
A process statement is a declarative region.
All concurrent statements have equivalent processes or block statement equivalents and equivalent processes, elaborated for simulation.
All those processes are separate declarative regions, albeit you're apparently only advocating allowing signal declarations as explicitly declared process declarative items.
Function calls are expressions, procedure calls are statements, concurrent procedure calls have equivalent processes for simulation.
A signal can only communicate between sequential statements in the same process by encountering a wait statement. A signal today would be declared in an enclosing declarative region (a block declarative item or a port declaration) or made visible by a use clause when declared as a package declarative item.
Note you can use wait statements and variables to the same effect internally to a process.
Where it get's interesting is using signals for their intended purpose - communicating between processes.
Case 1
Two or more processes in the same declarative region which also has a signal of the same name declared as in one process. Which signal declaration do other processes use?
Case 2
Three or more processes in the same declarative region with two of them declaring the same signal name. Which declaration does the third or other processes use?
Signal declarations in a process don't seem resolvable from a visibility perspective.
Consider how to extend the scope of a signal declaration to the enclosing declarative region by using a 'shared' signal declaration. That could resolve the second case if only one signal declaration were shared but not both and no declaration was visible in the enclosing declarative region. It doesn't address the first case at all, and selected names aren't allowed to use a process as a prefix (and would require an instantiation name if they were, incidentally requiring a process statement be labelled).
How would this be useful? It's ambiguous.
VHDL restricts where signals can be declared so that the visibility rules provide at most one possible declaration. The scope of a declaration doesn't extend into enclosing or adjacent declarative regions.
And as a cure instead of using paebbel's block statement you could also declare signals as package declarative items made privately visible by use clauses in particular processes. | Yes you should be able to do it and no you cannot and I don't believe VHDL2008 is fixing it (but a lot of awesome things are being fixed/added in VHDL2008). You can use always true generate statements (as already mentioned in a comment). Although if your using always true generate statements your module is probably to big and you should break it up.
I did just want to point out that you can still use/implement your pipeline register in a variable. if you swap the d and c assignments around. I know it's not as nice but I do use it occasionally and it synthesizes fine. Variables keep their values between consecutive runs of the process.
```

signal a, d : std_logic_vector(15 downto 0);

process (clk)
variable b : std_logic_vector(15 downto 0);
variable c : std_logic_vector(15 downto 0);
begin
if (rising_edge(clk)) then
b := foo_operation(a); -- could just be used to store an intermediary value
d <= baz_operation(c); -- the "output register" of this process
c := bar_operation(b); -- could e.g. be a pipeline
end if;
end process;
-- somewhere else:
a <= input_xyz;
output_xyz <= d

] | Adwhirl is great for doing this. Check it out: <https://www.adwhirl.com/home/dev>
Or when you want to do some crazy stuff you could even use a random number do decide which adview is shown, either iAd or AdMob ^^ | You can use something like AdWhirl to control multiple ad networks. That way you can allocate percentage of fill to each network.
Please note AdWhirl is not bad but we've had lots of problems/crashes when integrating it which we've had to sort out ourselves.
There are other similar tools but I ve not tried them. |

The `@media only screen and (min-width: 600px)` restricts the CSS rule to desktop devices with a minimum window width of 600px. For these the `width` of the page container created by jQuery Mobile is fixed to 600px, `margin: 0 auto` centers the page. The rest improves the result aesthetically.

@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
if (mProgressDialog.isShowing())
mProgressDialog.dismiss();
}

mVideoView.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer arg0) {
if (loadingDialog.isShowing()) {
loadingDialog.dismiss();
mVideoView.start();
}
}
});
```
2) Are you using Vitamio Bundle as a library?
If so, just open res/layout/mediacontroller.xml and edit the filename TextView to add visibility invisible (using gone breaks the ui)
Here you can customize as much as you want
```
<TextView
android:id="@+id/mediacontroller_file_name"
style="@style/MediaController_Text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:ellipsize="marquee"
android:singleLine="true"
android:visibility="invisible"
/>
``` | ```
mVideoView.setMediaController()
```
sets the MediaController widget to be displayed. Just create your own from scratch. |
26,223,356 | I have an MDI application where I'm trying to get a list of open windows for a `ComponentOne` Ribbon Menu. Using VB .NET.
I have this sub for instantiating a new child form within the MDI container:
```
Private Sub newButton_Click(sender As Object, e As EventArgs) Handles newButton.Click
' Create a new instance of the child form.
Dim ChildForm As New MyProject.MyForm
'Make it a child of this MDI form before showing it.
ChildForm.MdiParent = Me
m_ChildFormNumber += 1
ChildForm.Text = "Window " & m_ChildFormNumber
ChildForm.Show()
End Sub
```
Then in another Sub for the ribbon menu I try to get the list of windows.
I tried this:
```
Dim frm As System.Windows.Window
For Each frm In My.Application.Windows
frmButton = New C1.Win.C1Ribbon.RibbonButton(frm.Title)
...
```
But I get a `NullReferenceException` on the `System.Windows.Window` collection.
So then I tried this:
```
For Each Window In My.Application.Windows
frmButton = New C1.Win.C1Ribbon.RibbonButton(Window.Title)
...
```
But with that, I get "overload resolution failed because no accessible 'new' can be called without a narrowing conversion" on the arguments for the new `RibbonButton`. If I turn `Option Strict` On, of course it says it disallows late binding.
So I guess ultimately I'm wondering why my Windows collection is empty, even if I've opened child forms.
Then even beyond that, why does the New RibbonButton accept frm.Title but not Window.Title.
NOTE (in case you were wondering)...the frmButton is a class object:
```
Friend WithEvents frmButton As C1.Win.C1Ribbon.RibbonButton
```

task create_user: :environment do
User.create! first_name: "Foo", last_name: "Bar"

And then in the terminal run:
```
rake example:create_user

Locally this will be run in the context of your development database, and if run on Heroku it will be run while connected to your production database. I find this especially useful to assist with migrations, or modified tables. |

The latter suggest that I can define `main()` to return a non integer value.
How is it possible if main "shall" return int?

] | The full quote says `If the return type is not compatible with int, the termination status returned to the host environment is unspecified.`
That means it's undefined behavior. When `main()` exits, the program is essentially terminating, and the return value of main will be used as the exit status of the program. Since on most systems programs can only return an integer as their exit status, the return value of main is used as that exit code. Returning a string or pointer or whatever means you're returning something that the calling environment can't deal with. | >

That is, there's no existing prototype; whether you define it as `int main(void)`, `int main (int argc, char *argv[])`, or in "some other implementation-defined manner", you won't be conflicting with some implicit prototype.

If we read this as governing the return type as well, then there's no conflict with what comes later, because this basically says that the signature of `main` can be whatever you like, if it makes sense for the implementation — and later — but, if `main` returns `int` or something convertible to `int` then returning from `main` has to be equivalent to calling `exit` (since `exit` is declared `void exit(int)`).
One possible point against my reading, though, is that if this was the intent I would expect it to say that the behavior when the return type is not `int` is *implementation-defined*, rather than undefined. |

leads to confusion here. *implementation-defined* is the C standard jargon for *defined and documented* by the compiler provider. This doesn't mean that the programmer is free to chose an arbitrary prototype for `main`. It means that he *may* use a different prototype if his compiler documentation foresees it.
The only other platform specific return type I know of is `void`, which is allowed on some oldish platforms. For the arguments to `main`, I know of platforms that allow for a third parameter that passes a pointer to the environment. | >

6,707,062 | I am trying to assign a delegate's method to a UIButton using `addTarget:action:forControlEvents:`. Everything compiles without warnings, the IBOutlet is connected to the button in Interface Bulder (XCode 4). If I moves the delegate's method to the controller, it works fine. (All code worked fine, but I refactored to use a delegate, it's my first try with delegates and protocols.)
(added) The protocol declaration, placed before @interface in the .h:
```
@protocol MMGLVDelegate<NSObject>
-(void)receiveQuitRequest:(id)sender;
@end
```
In the controller interface, these properties:
```
@property (nonatomic, assign) id<TheDelegateProtocol> delegate;
@property (nonatomic, retain) IBOutlet UIButton *quitBtn;
```
In the controller implementation:
```
-(void)setDelegate:(id<MMGLVDelegate>)delegate {
DLog(@"MMGLVSegmented setDelegate: Entered");
_delegate = delegate;
[self.quitBtn addTarget:self.delegate action:@selector(receiveQuitRequest:)
forControlEvents:UIControlEventTouchUpInside];
}
```
Any help appreciated. Changing target to any of self.delegate, \_delegate, or delegate doesn't change app behavior.

I am not sure, but this may work in your case | I have a couple of minor suggestions:
1. Try disconnecting and re-connecting the delegate for the button in IB. I've noticed that sometimes this seems to reset it properly.
2. Clean and rebuild. Again, this helps to reset things that didn't get set properly. |

] | **create a structure called Cards** which has **two stored properties** one of **Card enum** type and another of **Bool type to keep track of status** here you can declare a function swap() which changes the status value:
```
struct Cards {
let card:Card? //This property stores an instance of Card enum
var status = true
mutating func swap()
{
self.status = !self.status
}
init(cardDigit: Int)
{
self.card = Card(digit: cardDigit)
}
init()
{
self.card = Card()
}
}
var aCard :Cards = Cards(cardDigit: 2)
aCard.status // returns true
aCard.swap()
aCard.status //returns false
```
You can remove the status computed property from enum, because we can access it from structure. | In case you do not want to use structs, another approach could be returning a new instance of the enum
```
func swap(status: Bool) -> Card {
var card = Card()
switch status {
case true:
card.status = false
case false:
card.status = true
}
return card
}

61,526,378 | This should be pretty simple, but after 3 hours of googling around, I apparently don't have the right wording to find the answer.
I have and XML return that I need to format for a page. I have no control of the return as it is coming from UPS's databases.
I have it formatted fine, but now I need to increase the returned rate by $4. This should be easy, but I'm very new to all of this and at a complete loss.
Here is the relevant portion of the returned XML:
```
<Response>
<ResponseStatusCode>1</ResponseStatusCode>
<ResponseStatusDescription>Success</ResponseStatusDescription></Response>
<RatedShipment>
<Service><Code>03</Code></Service>
<TotalCharges>
<CurrencyCode>USD</CurrencyCode>
<MonetaryValue>21.17</MonetaryValue></TotalCharges>
</RatedShipment>
</Response>
```
Here is the relevant portion of the XSL formatting:
```
<xsl:template match="/">
<select name="shipping_options" id="shipping_options">
<xsl:for-each select="/RatingServiceSelectionResponse/RatedShipment">
<xsl:choose>
<xsl:when test="Service/Code = 01">
<xsl:element name="option">
<xsl:attribute name='value'>
1!!!
<xsl:value-of select="TotalCharges/MonetaryValue"/>
</xsl:attribute>
UPS Next Day Air - $
<xsl:value-of select="format-number(TotalCharges/MonetaryValue, '###,###.00')"/>
</xsl:element>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</select>
```
Edit:
The format for the XSL is correct for other needs later. The desired final output looks like this:
```
<select name="shipping_options" id="shipping_options">
<option value="">Enter Zip Code To Update</option>
<option value="1!!!77.49">UPS Next Day Air - $77.49</option>
<option value="2!!!51.20">UPS 2nd Day Air - $51.20</option>
<option value="3!!!22.73">UPS Ground - $22.73</option>
<option value="4!!!38.01">UPS 3 Day Select - $38.01</option>
<option value="5!!!71.02">UPS Next Day Air Saver - $71.02</option>
<option value="6!!!108.01">UPS Next Day Air Early - $108.01</option>
<option value="8!!!0.00">Please call for freight pricing - $0.00</option>
<option value="9!!!0.00">Please call for international pricing - $0.00</option>
</select>
```
Edit #2:
it was literally as easy as it should have been. Just had to change this one bit to add "+4":
```
select="format-number(TotalCharges/MonetaryValue + 4, '###,###.00')"

] | As rowNumber seems to be a field of your object I assume that it's also a column in your table. In that case you can just add "ORDER BY rowNumber" to your HQL query and don't use Collections.sort | You need a Comparator which can sort by your desired criteria:
```
Comparator<? super TestFlow> comparator = new Comparator<TestFlow>() {
@Override
public int compare(TestFlow o1, TestFlow o2) {
return o1.getRowNumber().compareTo(o2.getRowNumber());
}
};
testFlow.sort(comparator);
```
And if you're using Java 8 or 9, this can be reduced to:
```
testFlow.sort(Comparator.comparing(TestFlow::getRowNumber));

20,842,630 | I have a StackPanel that contains a TextBox and a Combobox.
When I set the focus inside a textbox (not the first one), the Contents of the StackPanel "jumps" and goes to the top.
Below is the code. I have researched this and post the one I found and tried (but did not worK).
I want to prevent the "jumping".
So run the code below.
Scroll the vertical bar until you see:
```
Name Three <<Text Box
(No Selection) ComboBox \/
Name Four <<Text Box
(No Selection) ComboBox \/
```
Now put your cursor in the "Name Four" text box.......and watch it "jump" to the top.
(You don't see Three and Four now, you see Four and Five.)
My stackpanel is much more complex than this in real life, and its driving my end-users nutty.

This way, instead of trying to scroll each individual `StackPanel` into view at a time, and ensuring the full item is visible, it will try to scroll the entire `ListBox` into view, which exceeds the height allotted to the `ScrollViewer`, so it will use the smoother content-based scrolling that you want.
It should be noted that this will render the entire `ListBox` at once, without any virutalization, so it isn't advisable to use this method if you have a lot of rows and are depending on virtualization for performance. But based on your question, it doesn't sound like that is your case.
I'm also not positive, but you may have to nest this in one more panel as well to allow the ListBox to grow to whatever height it wants.

I think the key here is to create a class which implements IScrollInfo. I implemented one to override the amount the SV scrolls when using the mouse wheel. In my case, I cloned the default implementation from the [.NET source for ScrollContentProvider](http://www.dotnetframework.org/default.aspx/4@0/4@0/untmp/DEVDIV_TFS/Dev10/Releases/RTMRel/wpf/src/Framework/System/Windows/Controls/Primitives/ScrollContentPresenter@cs/1305600/ScrollContentPresenter@cs)) and changed some properties.
Internally, ScrollViewer will call the IScrollInfo::MakeVisible() on the desired child control. You could just ignore that request.
Create an instance of your own scroll provider to the scrollviewer using something like:
```
var myProvider = new MyScrollInfo();
myScrollViewer.ScrollInfo = myProvider;

This way, instead of trying to scroll each individual `StackPanel` into view at a time, and ensuring the full item is visible, it will try to scroll the entire `ListBox` into view, which exceeds the height allotted to the `ScrollViewer`, so it will use the smoother content-based scrolling that you want.
It should be noted that this will render the entire `ListBox` at once, without any virutalization, so it isn't advisable to use this method if you have a lot of rows and are depending on virtualization for performance. But based on your question, it doesn't sound like that is your case.
I'm also not positive, but you may have to nest this in one more panel as well to allow the ListBox to grow to whatever height it wants. See [this answer](https://stackoverflow.com/a/8490640/302677) for more details if needed. | Use this:

20,842,630 | I have a StackPanel that contains a TextBox and a Combobox.
When I set the focus inside a textbox (not the first one), the Contents of the StackPanel "jumps" and goes to the top.
Below is the code. I have researched this and post the one I found and tried (but did not worK).
I want to prevent the "jumping".
So run the code below.
Scroll the vertical bar until you see:
```
Name Three <<Text Box
(No Selection) ComboBox \/
Name Four <<Text Box
(No Selection) ComboBox \/
```
Now put your cursor in the "Name Four" text box.......and watch it "jump" to the top.
(You don't see Three and Four now, you see Four and Five.)
My stackpanel is much more complex than this in real life, and its driving my end-users nutty.

Try disabling the scrolling, and wrap it in another ScrollViewer:
```

<ListBox ScrollViewer.VerticalScrollBarVisibility="Disabled">
...
</ListBox>
</ScrollViewer>

``` | When a command like SetFocus runs on a child of the scrollviewer, it triggers a ReqestBringInto view on the scrrollviewer but the act of scrolling to the child controls is implemented under the covers by the scrollviewer's ScrollInfo object.
I think the key here is to create a class which implements IScrollInfo. I implemented one to override the amount the SV scrolls when using the mouse wheel. In my case, I cloned the default implementation from the [.NET source for ScrollContentProvider](http://www.dotnetframework.org/default.aspx/4@0/4@0/untmp/DEVDIV_TFS/Dev10/Releases/RTMRel/wpf/src/Framework/System/Windows/Controls/Primitives/ScrollContentPresenter@cs/1305600/ScrollContentPresenter@cs)) and changed some properties.
Internally, ScrollViewer will call the IScrollInfo::MakeVisible() on the desired child control. You could just ignore that request.
Create an instance of your own scroll provider to the scrollviewer using something like:
```
var myProvider = new MyScrollInfo();
myScrollViewer.ScrollInfo = myProvider;

If there has been a change in the editorial team it is somewhat their choice what direction they take the journal. The (hypothetical) outgoing editor is partially to blame for making a commitment they couldn't keep. Taking a moment for empathy, they were just trying to help the incoming editor out by having stuff in the pipeline.

732,283 | I have a OpenVPN server ruining on Unbuntu 14.04 server. Everything works fine, the client connects to the server and can ping the VPN server. I want the client use my internet as it were his internet but I also want to block the client to access my Home LAN. Below is my setup:
```

What I have done is enable packet forwarding
```
# Uncomment the next line to enable packet forwarding for IPv4

```
iptables -A INPUT -s 10.8.0.0/24 -d 192.168.1.0/24 -j DROP
``` | I think by default, there's no route to your Home LAN. You can ping the IP address on the OpenVPN server sitting on 192.168.1.0/24 but nothing else.

+----+---------------------+------------+------|
```
The relationships are
```
Orders >hasmany> Carts >hasmany> CartItems >hasmany> CartItemEvents
```
I now want to get all Orders with a 'status' column at the end. This column should display the lowest 'type' value of all cart item events belonging to the order. I only want to get the latest event for each order Item.
```
SELECT o.ID,
o.OrderNumber,
(SELECT MIN(type) FROM CartItemEvents cie WHERE cie.CartItemId=ci.Id
AND cie.EventDate=
(SELECT MAX(EventDate) FROM CartItemEvents WHERE ci.id=CartItemId))
AS 'status'
FROM Orders o
LEFT JOIN CartItems ci on o.CartId=ci.CartId
```
Unfortunately, I get multiple types for each order (one type for each item)
```
+----+-------------+--------+
| ID | OrderNumber | Status |
+----+-------------+--------+
|1 | ABDE45677 | 3 |
|1 | ABDE45677 | 4 |
|2 | ABFRTG456 | 2 |
+----+-------------+--------+
```
It seems like the function
```
SELECT MIN(type)
```
has no effect here, since removing MIN() brings the same result.
How can I get only the minimum type for each order?

] | You never want synchronous code when you can avoid it.
In this case I would recommend to use Promises in order to manage the seven requests to redis.
The [Bluebird promise library](http://bluebirdjs.com/docs/) can make most APIs promise-compatible in one line of code (read about [promisification](http://bluebirdjs.com/docs/api/promisification.html)), the API of redis is no exception. (The documentation of Bluebird even [uses redis as an example](http://bluebirdjs.com/docs/api/promise.promisifyall.html), and so does the [node-redis documentation](https://github.com/NodeRedis/node_redis#promises), so it's even "officially supported", if you care for that kind of thing.)
So what you seem to want is a function that checks up to seven asynchronous calls to `sismember` and resolves to an overal positive result as soon as the first of them has a positive result - [Promise#any()](http://bluebirdjs.com/docs/api/promise.any.html) can do that.
```
var Promise = require('bluebird');
var _ = require('lodash');
var redis = require('redis');
Promise.promisifyAll(redis);
function checkBlacklist(hashToken) {
var blacklistChecks = _.range(7).map((day) => {
return redis.sismemberAsync(`blacklist${day}`, hashToken);
});
return Promise.any(blacklistChecks);
}
```
usage
```
checkBlacklist('some_token').then((result) => {
// do something with the result
}).catch((err) => {
// an error has occurred - handle it or rethrow it
});
``` | If multiple redis ops are involved, generally I prefer to write lua script and then call it through my nodejs program. This is an unrelated example, but it shows how you can use lua through nodejs.
example: get\_state.lua
```
local jobId = KEYS[1]
local jobExists = redis.pcall('exists', jobId)
if jobExists == 0 or jobExists == nil then
return 404 -- not found.
end
-- check the job state
local st = tonumber(redis.pcall('hmget', jobId, 'ctlState')[1])
if st == nil then
st = 12002 -- job running, unless explicitly stated otherwise
end
return st
```
NodeJS code that uses lua: say index.js
```
...
// List of script files
var scriptMap = {
getState: {file:'./scripts/get_state.lua'}
};
...
// A function to load the script file to Redis and cache the sha.
function loadScript(script) {
logger.trace("loadScript(): executing...");
if (scriptMap[script]['hash']) {
logger.trace("Sript already loaded. Returning without loading again...");
return Promise.resolve(scriptMap[script]['hash']);
}
//load from file and send to redis
logger.trace("Loading script from file %s...", scriptMap[script].file);
return fs.readFileAsync(scriptMap[script].file).then(function(data) {
return getConnection().then(function(conn) {
logger.trace("Loading script to Redis...");
return conn.scriptAsync('load', data)
})
})
}
```
And, finally, a function that uses the cached sha digest to execute the script:
```
getJobState: function(jobId) {
return loadScript('getState').then(function(hash) {
return getConnection().then(function (conn) {
return conn.evalshaAsync(hash, 1, jobId)
})
})
},

It is not required, but is good practice for labels that have a direct form element to focus on (it wouldn't make much sense for a label that doesn't have a counterpart on a form).
The syntax is the same for HTML 5. | For binds the `<label>` and the `<input>` field together. `for` should point to the `id` of the `<input>`. It is not actually needed, but it is useful for example on radio buttons, where the user can click the label to check the radio button, thus creating a larger click area and a better user experience.
You use `for` the same in way HTML5 as you do in HTML4 or XHTML or whatever you used before. |
