Programs & Examples On #Region management

Use clearAllTables() with RXJava like below inorder to avoid java.lang.IllegalStateException: Cannot access database on the main thread since it may potentially lock the UI for a long period of time.

Completable.fromAction(new Action() {
        @Override
        public void run() throws Exception {
            getRoomDatabase().clearAllTables();
        }
    }).subscribeOn(getSchedulerProvider().io())
            .observeOn(getSchedulerProvider().ui())
            .subscribe(new Action() {
                @Override
                public void run() throws Exception {
                    Log.d(TAG, "--- clearAllTables(): run() ---");
                    getInteractor().setUserAsLoggedOut();
                    getMvpView().openLoginActivity();
                }
            }, new Consumer<Throwable>() {
                @Override
                public void accept(Throwable throwable) throws Exception {
                    Log.d(TAG, "--- clearAllTables(): accept(Throwable throwable) ----");
                    Log.d(TAG, "throwable.getMessage(): "+throwable.getMessage());


                }
            });

If you're planning to work with function pointers

#define lambda(return_type, function_body)\
    ({ return_type __fn__ function_body __fn__; })

#define array_len(arr) (sizeof(arr)/sizeof(arr[0]))

#define foreachnf(type, item, arr, arr_length, func) {\
    void (*action)(type item) = func;\
    for (int i = 0; i<arr_length; i++) action(arr[i]);\
}

#define foreachf(type, item, arr, func)\
    foreachnf(type, item, arr, array_len(arr), func)

#define foreachn(type, item, arr, arr_length, body)\
    foreachnf(type, item, arr, arr_length, lambda(void, (type item) body))

#define foreach(type, item, arr, body)\
    foreachn(type, item, arr, array_len(arr), body)

Usage:

int ints[] = { 1, 2, 3, 4, 5 };
foreach(int, i, ints, {
    printf("%d\n", i);
});

char* strs[] = { "hi!", "hello!!", "hello world", "just", "testing" };
foreach(char*, s, strs, {
    printf("%s\n", s);
});

char** strsp = malloc(sizeof(char*)*2);
strsp[0] = "abcd";
strsp[1] = "efgh";
foreachn(char*, s, strsp, 2, {
    printf("%s\n", s);
});

void (*myfun)(int i) = somefunc;
foreachf(int, i, ints, myfun);

But I think this will work only on gcc (not sure).

Have your tried json-io (https://github.com/jdereg/json-io)?

This library allows you to serialize / deserialize any Java object graph, including object graphs with cycles in them (e.g., A->B, B->A). It does not require your classes to implement any particular interface or inherit from any particular Java class.

In addition to serialization of Java to JSON (and JSON to Java), you can use it to format (pretty print) JSON:

String niceFormattedJson = JsonWriter.formatJson(jsonString)

What everyone seems to miss is that the semi-colons in JavaScript are not statement terminators but statement separators. It's a subtle difference, but it is important to the way the parser is programmed. Treat them like what they are and you will find leaving them out will feel much more natural.

I've programmed in other languages where the semi-colon is a statement separator and also optional as the parser does 'semi-colon insertion' on newlines where it does not break the grammar. So I was not unfamiliar with it when I found it in JavaScript.

I don't like noise in a language (which is one reason I'm bad at Perl) and semi-colons are noise in JavaScript. So I omit them.

I encountered this on jython client. The server was only talking TLS and the client using SSL context.

javax.net.ssl.SSLContext.getInstance("SSL")

Once the client was to TLS, things started working.

Please try with just giving the path from where you want to pull the files I just got the files from sdcard like

adb pull sdcard/

do NOT give * like to broaden the search or to filter out. ex: adb pull sdcard/*.txt --> this is invalid.

just give adb pull sdcard/

If you want to install PHP extensions in ubuntu.

first know which PHP version is active.

php -v

After that install needed plugin using this command.

sudo apt install php7.0-bcmath

you can replace php7.0-bcmath to php-PHPVersion-extensionName

The Css vertical-align property should help you out here:

vertical-align: bottom;

is what you need for your smaller header :)

You could have done a:

git add -u -n

To check which files you modified and are going to be added (dry run: -n option), and then

git add -u

To add just modified files

<div style="background: red;">
    The inline styles for this div should make it red.
</div>

div[style] {
   background: yellow !important;
}

Below is the link for more details: http://css-tricks.com/override-inline-styles-with-css/

This approach gives you the whole flexibility! ES6 / VanillaJS!

html:

<input type="file" style="display:none;"></input>
<button>Upload file</button>

javascript:

document.querySelector('button').addEventListener('click', () => {
  document.querySelector('input[type="file"]').click();
});

This hides the input-file button, but under the hood clicks it from another normal button, that you can obviously style like any other button. This is the only solution with no downside apart from a useless DOM-node. Thanks to display:none;, the input-button does not reserve any visible space in the DOM.

(I don't know anymore to whom to give props for this. But I got that idea from somewhere here on Stackoverflow.)

There's a C implementation here:

http://www.cs.rit.edu/~ncs/color/t_convert.html

Should be very straightforward to convert to C#, as almost no functions are called - just calculations.

The answer was to install the plugin individually. I installed all the three plugins shown in the screenshot together. And it created the issue. I had to install each plugin individually and then it worked fine. I am able to format the JSON string.

When a Derived class Object is assigned to Base class Object, all the members of derived class object is copied to base class object except the members which are not present in the base class. These members are Sliced away by the compiler. This is called Object Slicing.

Here is an Example:

#include<bits/stdc++.h>
using namespace std;
class Base
{
    public:
        int a;
        int b;
        int c;
        Base()
        {
            a=10;
            b=20;
            c=30;
        }
};
class Derived : public Base
{
    public:
        int d;
        int e;
        Derived()
        {
            d=40;
            e=50;
        }
};
int main()
{
    Derived d;
    cout<<d.a<<"\n";
    cout<<d.b<<"\n";
    cout<<d.c<<"\n";
    cout<<d.d<<"\n";
    cout<<d.e<<"\n";


    Base b = d;
    cout<<b.a<<"\n";
    cout<<b.b<<"\n";
    cout<<b.c<<"\n";
    cout<<b.d<<"\n";
    cout<<b.e<<"\n";
    return 0;
}

It will generate:

[Error] 'class Base' has no member named 'd'
[Error] 'class Base' has no member named 'e'

sed can perform text transformations on input stream from a file or from a pipeline. Example:

echo 'C:\foo\bar.xml' | sed 's/\\/\//g'

gets

C:/foo/bar.xml

You will have to use cookie to store the value across page refresh. You can use any one of the many javascript based cookie libraries to simplify the cookie access, like this one

If you want to support only html5 then you can think of Storage api like localStorage/sessionStorage

Ex: using localStorage and cookies library

var mode = getStoredValue('myPageMode');

function buttonClick(mode) {
    mode = mode;
    storeValue('myPageMode', mode);
}

function storeValue(key, value) {
    if (localStorage) {
        localStorage.setItem(key, value);
    } else {
        $.cookies.set(key, value);
    }
}

function getStoredValue(key) {
    if (localStorage) {
        return localStorage.getItem(key);
    } else {
        return $.cookies.get(key);
    }
}

You aren't creating any buttons, you just have an empty list.

You can forget the list and just create the buttons in the loop.

private void button1_Click(object sender, EventArgs e) 
{     
     int top = 50;
     int left = 100;

     for (int i = 0; i < 10; i++)     
     {         
          Button button = new Button();   
          button.Left = left;
          button.Top = top;
          this.Controls.Add(button);      
          top += button.Height + 2;
     }
} 

Instead of the hack you currently use to hide the button, it would be much simpler to set visibility: collapse; in the style attribute. However, I would still recommend using a bit of simple Javascript to submit the form. As far as I understand, support for such things is ubiquitous nowadays.

Check for nil and unwrap using "!":

let color = colorChoiceSegmentedControl.titleForSegmentAtIndex(colorChoiceSegmentedControl.selectedSegmentIndex)

println(color) // Optional("Red")

if color != nil {
    println(color!) // "Red"
    let imageURLString = "http://hahaha.com/ha.php?color=\(color!)"
    println(imageURLString)
    //"http://hahaha.com/ha.php?color=Red"
}

I got this problem and it turns out that JBossDevStudio 9.1 on Windows is a 32-bit program. Eclipse, and thus the JBossDevStudio, does not work with the wrong type of JVM. 64-bit eclipse needs a 64-bit JVM, 32-bit eclipse needs a 32-bit JVM. Thus configuring Eclipse to run with my installed 64-bit JDK did not work.

Installing a 32 bit JDK and running Eclipse from that solved the problem.

At least for one of my projects, an other where I had tried to configure a runtime JDK in the Eclipse project properties is still broken.

As mentioned below, and detailed in "How would I extract a single file (or changes to a file) from a git stash?", you can apply use git checkout or git show to restore a specific file.

git checkout stash@{0} -- <filename>

With Git 2.23+ (August 2019), use git restore, which replaces the confusing git checkout command:

git restore -s stash@{0} -- <filename>

That does overwrite filename: make sure you didn't have local modifications, or you might want to merge the stashed file instead.

(As commented by Jaime M., for certain shell like tcsh where you need to escape the special characters, the syntax would be: git checkout 'stash@{0}' -- <filename>)

or to save it under another filename:

git show stash@{0}:<full filename>  >  <newfile>

(note that here <full filename> is full pathname of a file relative to top directory of a project (think: relative to stash@{0})).

yucer suggests in the comments:

If you want to select manually which changes you want to apply from that file:

git difftool stash@{0}..HEAD -- <filename>

Vivek adds in the comments:

Looks like "git checkout stash@{0} -- <filename>" restores the version of the file as of the time when the stash was performed -- it does NOT apply (just) the stashed changes for that file.
To do the latter:

git diff stash@{0}^1 stash@{0} -- <filename> | git apply

(as commented by peterflynn, you might need | git apply -p1 in some cases, removing one (p1) leading slash from traditional diff paths)

As commented: "unstash" (git stash pop), then:

• add what you want to keep to the index (git add)
• stash the rest: git stash --keep-index

The last point is what allows you to keep some file while stashing others.
It is illustrated in "How to stash only one file out of multiple files that have changed".

here is what i did. wanted to make sure i could click any of the children in my datepicker without closing it.

$('html').click(function(e){
    if (e.target.id == 'menu_content' || $(e.target).parents('#menu_content').length > 0) {
        // clicked menu content or children
    } else {
        // didnt click menu content
    }
});

my actual code:

$('html').click(function(e){
    if (e.target.id != 'datepicker'
        && $(e.target).parents('#datepicker').length == 0
        && !$(e.target).hasClass('datepicker')
    ) {
        $('#datepicker').remove();
    }
});

If you are using HTML 5, there is the <audio> element.

On MDN:

The audio element is used to embed sound content in an HTML or XHTML document. The audio element was added as part of HTML5.

Update:

In order to play audio in the browser in HTML versions before 5 (including XHTML), you need to use one of the many flash audio players.

I use the following alternative to get default/optional params and "kind-of-overloaded" constructors with variable number of params:

private x?: number;
private y?: number;

constructor({x = 10, y}: {x?: number, y?: number}) {
 this.x = x;
 this.y = y;
}

I know it's not the prettiest code ever, but one gets used to it. No need for the additional Interface and it allows private members, which is not possible when using the Interface.

now with ES5, bind method Function prototype :

setInterval(funca.bind(null,10,3),500);

Reference here

Perhaps you could think about the problem in a different way. WebClient and HttpClient are essentially different implementations of the same thing. What I recommend is implementing the Dependency Injection pattern with an IoC Container throughout your application. You should construct a client interface with a higher level of abstraction than the low level HTTP transfer. You can write concrete classes that use both WebClient and HttpClient, and then use the IoC container to inject the implementation via config.

What this would allow you to do would be to switch between HttpClient and WebClient easily so that you are able to objectively test in the production environment.

So questions like:

Will HttpClient be a better design choice if we upgrade to .Net 4.5?

Can actually be objectively answered by switching between the two client implementations using the IoC container. Here is an example interface that you might depend on that doesn't include any details about HttpClient or WebClient.

HttpClient Implementation

You can use Task.Run to make WebClient run asynchronously in its implementation.

Dependency Injection, when done well helps alleviate the problem of having to make low level decisions upfront. Ultimately, the only way to know the true answer is try both in a live environment and see which one works the best. It's quite possible that WebClient may work better for some customers, and HttpClient may work better for others. This is why abstraction is important. It means that code can quickly be swapped in, or changed with configuration without changing the fundamental design of the app.

BTW: there are numerous other reasons that you should use an abstraction instead of directly calling one of these low-level APIs. One huge one being unit-testability.

No. From the XHTML 1.0 Spec

In XML, fragment identifiers are of type ID, and there can only be a single attribute of type ID per element. Therefore, in XHTML 1.0 the id attribute is defined to be of type ID. In order to ensure that XHTML 1.0 documents are well-structured XML documents, XHTML 1.0 documents MUST use the id attribute when defining fragment identifiers on the elements listed above. See the HTML Compatibility Guidelines for information on ensuring such anchors are backward compatible when serving XHTML documents as media type text/html.

Simple one, just do like this..

ListViewItem lvi = new ListViewItem(pet.Name);
    lvi.SubItems.Add(pet.Type);
    lvi.SubItems.Add(pet.Age);
    listView.Items.Add(lvi);

Short answer is that you don't 'decrypt' the password (because it's not encrypted - it's hashed).

The long answer is that you shouldn't send the user their password by email, or any other way. If the user has forgotten their password, you should send them a password reset email, and allow them to change their password on your website.

Laravel has most of this functionality built in (see the Laravel documentation - I'm not going to replicate it all here. Also available for versions 4.2 and 5.0 of Laravel).

For further reading, check out this 'blogoverflow' post: Why passwords should be hashed.

For all the pythonian zealots out there I'm sure Johan Cleeze would approve of your dogmatism ;). I'm leaving this answer keep demeriting it It actually makes me more confidant. Leave a comment you chickens!

For python 3.6

class SomeClass:

    def attr_list1(self, should_print=False):

        for k in self.__dict__.keys():
            v = self.__dict__.__getitem__(k)
            if should_print:
                print(f"attr: {k}    value: {v}")

    def attr_list(self, should_print=False):

        b = [(k, v) for k, v in self.__dict__.items()]
        if should_print:
            [print(f"attr: {a[0]}    value: {a[1]}") for a in b]
        return b

using System.Configuration;


string conn = ConfigurationManager.ConnectionStrings["ConStringName"].ToString();

The state of the checkbox will be reflected on whatever model you have it bound to, in this case, $scope.answers[item.questID]

for me this error cause of different stuff. i have two ajax call in my page. first one for save comment and another one for save like. in my routes.php i had this:

Route::post('posts/show','PostController@save_comment');
Route::post('posts/show','PostController@save_like');

and i got 500 internal server error for my save like ajax call. so i change second line http request type to PUT and error goes away. you can use PATCH too. maybe it helps.

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

In case of detached HEAD, commits work like normal, except no named branch gets updated. To get master branch updated with your committed changes, make a temporary branch where you are (this way the temporary branch will have all the committed changes you have made in the detached HEAD) , then switch to the master branch and merge the temporary branch with the master.

git branch  temp
git checkout master
git merge temp

This is more of an example where TABLOCK did not work for me and TABLOCKX did.

I have 2 sessions, that both use the default (READ COMMITTED) isolation level:

Session 1 is an explicit transaction that will copy data from a linked server to a set of tables in a database, and takes a few seconds to run. [Example, it deletes Questions] Session 2 is an insert statement, that simply inserts rows into a table that Session 1 doesn't make changes to. [Example, it inserts Answers].

(In practice there are multiple sessions inserting multiple records into the table, simultaneously, while Session 1 is running its transaction).

Session 1 has to query the table Session 2 inserts into because it can't delete records that depend on entries that were added by Session 2. [Example: Delete questions that have not been answered].

So, while Session 1 is executing and Session 2 tries to insert, Session 2 loses in a deadlock every time.

So, a delete statement in Session 1 might look something like this: DELETE tblA FROM tblQ LEFT JOIN tblX on ... LEFT JOIN tblA a ON tblQ.Qid = tblA.Qid WHERE ... a.QId IS NULL and ...

The deadlock seems to be caused from contention between querying tblA while Session 2, [3, 4, 5, ..., n] try to insert into tblA.

In my case I could change the isolation level of Session 1's transaction to be SERIALIZABLE. When I did this: The transaction manager has disabled its support for remote/network transactions.

So, I could follow instructions in the accepted answer here to get around it: The transaction manager has disabled its support for remote/network transactions

But a) I wasn't comfortable with changing the isolation level to SERIALIZABLE in the first place- supposedly it degrades performance and may have other consequences I haven't considered, b) didn't understand why doing this suddenly caused the transaction to have a problem working across linked servers, and c) don't know what possible holes I might be opening up by enabling network access.

There seemed to be just 6 queries within a very large transaction that are causing the trouble.

So, I read about TABLOCK and TabLOCKX.

I wasn't crystal clear on the differences, and didn't know if either would work. But it seemed like it would. First I tried TABLOCK and it didn't seem to make any difference. The competing sessions generated the same deadlocks. Then I tried TABLOCKX, and no more deadlocks.

So, in six places, all I needed to do was add a WITH (TABLOCKX).

So, a delete statement in Session 1 might look something like this: DELETE tblA FROM tblQ q LEFT JOIN tblX x on ... LEFT JOIN tblA a WITH (TABLOCKX) ON tblQ.Qid = tblA.Qid WHERE ... a.QId IS NULL and ...

Just for completeness I would like to add my solution. I ended up doing this with the standard ed:

ed -s sometextfile <<< $'-2,$d\nwq'

This deletes the last 2 lines using in-place editing (although it does use a temporary file in /tmp !!)

Consider following situation. Suppose you want to check whether type A is a super class of the type of obj, you can go either

... A.class.isAssignableFrom(obj.getClass()) ...

OR

... obj instanceof A ...

But the isAssignableFrom solution requires that the type of obj be visible here. If this is not the case (e.g., the type of obj might be of a private inner class), this option is out. However, the instanceof solution would always work.

In addition to all the other answers, you could use switch. But it does seem a bit long.

switch ($result->vocation) {
case 1:
    echo 'Sorcerer';
    break;

case 2:
    echo 'Druid';
    break;

case 3:
    echo 'Paladin';
    break;

case 4:
    echo 'Knight';
    break;

case 5:
    echo 'Master Sorcerer';
    break;

case 6:
    echo 'Elder Druid';
    break;

case 7:
    echo 'Royal Paladin';
    break;

default:
    echo 'Elite Knight';
    break;
}

From the documentation I found this

JObject o = new JObject(
   new JProperty("Name", "John Smith"),
   new JProperty("BirthDate", new DateTime(1983, 3, 20))
);

JsonSerializer serializer = new JsonSerializer();
Person p = (Person)serializer.Deserialize(new JTokenReader(o), typeof(Person));

Console.WriteLine(p.Name);

The class definition for Person should be compatible to the following:

class Person {
    public string Name { get; internal set; }
    public DateTime BirthDate { get; internal set; }
}

Edit

If you are using a recent version of JSON.net and don't need custom serialization, please see TienDo's answer above (or below if you upvote me :P ), which is more concise.

Try using RenderAction("myPartial","Account");

You can use white-space: nowrap; to define this behaviour:

// HTML:

.nowrap {_x000D_
  white-space: nowrap ;_x000D_
}

<p>_x000D_
      <span class="nowrap">How do I wrap this line of text</span>_x000D_
      <span class="nowrap">- asked by Peter 2 days ago</span>_x000D_
    </p>

// CSS:
.nowrap {
  white-space: nowrap ;
}

Try the SetField method:

table.Rows[i].SetField(column, value);
table.Rows[i].SetField(columnIndex, value);
table.Rows[i].SetField(columnName, value);

This should get the job done and is a bit "cleaner" than using Rows[i][j].

After trying everything that's out there without success, I found out, by accident, a functional and very easy way to get the action bar's default height.

Only tested in API 25 and 24

C#

Resources.GetDimensionPixelSize(Resource.Dimension.abc_action_bar_default_height_material); 

Java

getResources().getDimensionPixelSize(R.dimen.abc_action_bar_default_height_material);

To share some analysis info. With a simple test how long it takes to read ~1180 lines of values.

If you need to read the data very fast, use the good old BufferedReader FileReader example. It took me ~8ms

The Scanner is much slower. Took me ~138ms

The nice Java 8 Files.lines(...) is the slowest version. Took me ~388ms.

Well, getting full path is not possible but we can have a temporary path.

Try This:

It'll give you a temporary path not the accurate path, you can use this script if you want to show selected images as in this jsfiddle example(Try it by selectng images as well as other files):-

JSFIDDLE

Here is the code :-

HTML:-

<input type="file" id="i_file" value=""> 
<input type="button" id="i_submit" value="Submit">
    <br>
<img src="" width="200" style="display:none;" />
        <br>
<div id="disp_tmp_path"></div>

JS:-

$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
    $("img").fadeIn("fast").attr('src',URL.createObjectURL(event.target.files[0]));

    $("#disp_tmp_path").html("Temporary Path(Copy it and try pasting it in browser address bar) --> <strong>["+tmppath+"]</strong>");
});

Its not exactly what you were looking for, but may be it can help you somewhere.

As others have already said, parameters passed through the command line can be accessed in batch files with the notation %1 to %9. There are also two other tokens that you can use:

• %0 is the executable (batch file) name as specified in the command line.
• %* is all parameters specified in the command line -- this is very useful if you want to forward the parameters to another program.

There are also lots of important techniques to be aware of in addition to simply how to access the parameters.

Checking if a parameter was passed

This is done with constructs like IF "%~1"=="", which is true if and only if no arguments were passed at all. Note the tilde character which causes any surrounding quotes to be removed from the value of %1; without a tilde you will get unexpected results if that value includes double quotes, including the possibility of syntax errors.

Handling more than 9 arguments (or just making life easier)

If you need to access more than 9 arguments you have to use the command SHIFT. This command shifts the values of all arguments one place, so that %0 takes the value of %1, %1 takes the value of %2, etc. %9 takes the value of the tenth argument (if one is present), which was not available through any variable before calling SHIFT (enter command SHIFT /? for more options).

SHIFT is also useful when you want to easily process parameters without requiring that they are presented in a specific order. For example, a script may recognize the flags -a and -b in any order. A good way to parse the command line in such cases is

:parse
IF "%~1"=="" GOTO endparse
IF "%~1"=="-a" REM do something
IF "%~1"=="-b" REM do something else
SHIFT
GOTO parse
:endparse
REM ready for action!

This scheme allows you to parse pretty complex command lines without going insane.

Substitution of batch parameters

For parameters that represent file names the shell provides lots of functionality related to working with files that is not accessible in any other way. This functionality is accessed with constructs that begin with %~.

For example, to get the size of the file passed in as an argument use

ECHO %~z1

To get the path of the directory where the batch file was launched from (very useful!) you can use

ECHO %~dp0

You can view the full range of these capabilities by typing CALL /? in the command prompt.

The primary reason is when you don't want to run the code directly, but rather, want to inspect it. This can be for any number of reasons:

• Mapping the code to a different environment (ie. C# code to SQL in Entity Framework)
• Replacing parts of the code in runtime (dynamic programming or even plain DRY techniques)
• Code validation (very useful when emulating scripting or when doing analysis)
• Serialization - expressions can be serialized rather easily and safely, delegates can't
• Strongly-typed safety on things that aren't inherently strongly-typed, and exploiting compiler checks even though you're doing dynamic calls in runtime (ASP.NET MVC 5 with Razor is a nice example)

I use this extension, almost same as Varun's, but this one (below) is all-purpose:

 extension Array where Element: Equatable  {
        mutating func delete(element: Iterator.Element) {
                self = self.filter{$0 != element }
        }
    }

Go to gradle.properties file (project root directory) and add these options.

systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=user
systemProp.http.proxyPassword=password
systemProp.http.nonProxyHosts=localhost
systemProp.http.auth.ntlm.domain=domain

systemProp.https.proxyHost=www.somehost.org
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=user
systemProp.https.proxyPassword=password
systemProp.https.nonProxyHosts=localhost
systemProp.https.auth.ntlm.domain=domain

The correct answer is

Options -Indexes

You must have been thinking of

AllowOverride All

https://httpd.apache.org/docs/2.2/howto/htaccess.html

.htaccess files (or "distributed configuration files") provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

Unexpected 'O' error is thrown when JSON data or String happens to get parsed.

If it's string, it's already stringfied. Parsing ends up with Unexpected 'O' error.

I faced similar( although in different context), I solved the following error by removing JSON Producer.

    @POST
    @Produces({ **MediaType.APPLICATION_JSON**})
    public Response login(@QueryParam("agentID") String agentID , Officer aOffcr ) {
      return Response.status(200).entity("OK").build();

  }

The response contains "OK" string return. The annotation marked as @Produces({ **MediaType.APPLICATION_JSON})** tries to parse the string to JSON format which results in Unexpected 'O'.

Removing @Produces({ MediaType.APPLICATION_JSON}) works fine. Output : OK

Beware: Also, on client side, if you make ajax request and use JSON.parse("OK"), it throws Unexpected token 'O'

O is the first letter of the string

JSON.parse(object) compares with jQuery.parseJSON(object);

JSON.parse('{ "name":"Yergalem", "city":"Dover"}'); --- Works Fine

You can't read mouse position in jQuery without using an event. Note firstly that the event.pageX and event.pageY properties exists on any event, so you could do:

$('#myEl').click(function(e) {
    console.log(e.pageX);
});

Your other option is to use a closure to give your whole code access to a variable that is updated by a mousemove handler:

var mouseX, mouseY;
$(document).mousemove(function(e) {
    mouseX = e.pageX;
    mouseY = e.pageY;
}).mouseover(); // call the handler immediately

// do something with mouseX and mouseY

Redirect the output to a file like this:

./a.sh > somefile 2>&1 &

This will redirect both stdout and stderr to the same file. If you want to redirect stdout and stderr to two different files use this:

./a.sh > stdoutfile 2> stderrfile &

You can use /dev/null as one or both of the files if you don't care about the stdout and/or stderr.

See bash manpage for details about redirections.

Only a partial solution: The only way I could get this to work for IE was to wrap each div in it's own table and set the page-break-inside on the table to avoid.

If you really don't care about props then the widest possible type is React.ReactType.

This would allow passing native dom elements as string. React.ReactType covers all of these:

renderGreeting('button');
renderGreeting(() => 'Hello, World!');
renderGreeting(class Foo extends React.Component {
   render() {
      return 'Hello, World!'
   }
});

If you are comfortable with Visual Studio environment,

Small project: jGRASP with gcc Large project: Cocotron

I heard there are emulators, but I could find only Apple II Emulator http://virtualapple.org/. It looks like limited to games.

Make sure that you do not have any null or NaN values in the list you want to sort. If there are NaN values, then your sort will be off, impacting the sorting of the non-null values.

Check out Python: sort function breaks in the presence of nan

A note on relative paths to complement the other answers.

When doing infrastructure as code I'm usually using roles and tasks that accept relative paths, specially for files defined in those roles.

Special variables like playbook_dir and role_path are very useful to create the absolute paths needed to test for existence.

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

The other answer may be better, but here's what I was doing. First, I made a function called progress which prints off the backspace character:

def progress(x):
    out = '%s things done' % x  # The output
    bs = '\b' * 1000            # The backspace
    print bs,
    print out,

Then I called it in a loop in my main function like so:

def main():
    for x in range(20):
        progress(x)
    return

This will of course erase the entire line, but you can mess with it to do exactly what you want. I ended up make a progress bar using this method.

Like docs say:

When the command line does not specify where to push with the <repository> argument, branch.*.remote configuration for the current branch is consulted to determine where to push. If the configuration is missing, it defaults to origin.

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

• https://github.com/webpack/webpack/issues/3216
• https://angular.io/guide/build#configure-size-budgets

SCRUM :

SCRUM is a type of Agile approach. It is a Framework not a Methodology.

It does not provide detailed instructions to what needs to be done rather most of it is dependent on the team that is developing the software. Because the developing the project knows how the problem can be solved that is why much is left on them

Cross-functional and self-organizing teams are essential in case of scrum. There is no team leader in this case who will assign tasks to the team members rather the whole team addresses the issues or problems. It is cross-functional in a way that everyone is involved in the project right from the idea to the implementation of the project.

The advantage of scrum is that a project’s direction to be adjusted based on completed work, not on speculation or predictions.

Roles Involved : Product Owner, Scrum Master, Team Members

Agile Methodology :

Build Software applications that are unpredictable in nature

Iterative and incremental work cadences called sprints are used in this methodology.

Both Agile and SCRUM follows the system -- some of the features are developed as a part of the sprint and at the end of each sprint; the features are completed right from coding, testing and their integration into the product. A demonstration of the functionality is provided to the owner at the end of each sprint so that feedback can be taken which can be helpful for the next sprint.

Manifesto for Agile Development :

1. Individuals and interactions over processes and tools
2. Working software over comprehensive documentation
3. Customer collaboration over contract negotiation
4. Responding to change over following a plan

That is, while there is value in the items on the right, we value the items on the left more.

For me, it worked when I selected the correct bit of my Python version, NOT the one of my computer version.

Mine is 32bit, and my computer is 64bit. That was the problem and the 32bit version of fixed it.

To be exact, here is the one that I downloaded and worked for me:

mysqlclient-1.3.13-cp37-cp37m-win32.whl

Once again, just make sure to chose your python version of bits and not your system one.

We can use Object.requireNonNull static method of Object class. Implementation is below

public void someMethod(SomeClass obj) {
    Objects.requireNonNull(obj, "Validation error, obj cannot be null");
}

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

dict(zip([1,2,3,4], [a,b,c,d]))

If the lists are big you should use itertools.izip.

If you have more keys than values, and you want to fill in values for the extra keys, you can use itertools.izip_longest.

Here, a, b, c, and d are variables -- it will work fine (so long as they are defined), but you probably meant ['a','b','c','d'] if you want them as strings.

zip takes the first item from each iterable and makes a tuple, then the second item from each, etc. etc.

dict can take an iterable of iterables, where each inner iterable has two items -- it then uses the first as the key and the second as the value for each item.

I realize this question is for Swift, but here is the Xamarin equivalent code of the accepted answer if someone is interested.

var indexPath = NSIndexPath.FromRowSection(rowIndex, 0);
tableView.ReloadRows(new NSIndexPath[] { indexPath }, UITableViewRowAnimation.Top);

You can add parameter columns or use dict with key which is converted to column name:

np.random.seed(123)
e = np.random.normal(size=10)  
dataframe=pd.DataFrame(e, columns=['a']) 
print (dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

e_dataframe=pd.DataFrame({'a':e}) 
print (e_dataframe)
          a
0 -1.085631
1  0.997345
2  0.282978
3 -1.506295
4 -0.578600
5  1.651437
6 -2.426679
7 -0.428913
8  1.265936
9 -0.866740

Try the following code to display scroll bar always on your page,

::-webkit-scrollbar {
  -webkit-appearance: none;
  width: 10px;
}

::-webkit-scrollbar-thumb {
  border-radius: 5px;
  background-color: rgba(0,0,0,.5);
  -webkit-box-shadow: 0 0 1px rgba(255,255,255,.5);
}

this will always show the vertical and horizontal scroll bar on your page. If you need only a vertical scroll bar then put overflow-x: hidden

A way to use a custom sort function

//func has to return 0 in the case in which they are equal
sort_unique = function(arr,func) {
        func = func || function (a, b) {
            return a*1 - b*1;
        };
        arr = arr.sort(func);
        var ret = [arr[0]];
        for (var i = 1; i < arr.length; i++) {
            if (func(arr[i-1],arr[i]) != 0) 
                ret.push(arr[i]);
            }
        }
        return ret;
    }

Example: desc order for an array of objects

MyArray = sort_unique(MyArray , function(a,b){
            return  b.iterator_internal*1 - a.iterator_internal*1;
        });

It's the new feature in C# 6 called Interpolated Strings.

The easiest way to understand it is: an interpolated string expression creates a string by replacing the contained expressions with the ToString representations of the expressions' results.

For more details about this, please take a look at MSDN.

Now, think a little bit more about it. Why this feature is great?

For example, you have class Point:

public class Point
{
    public int X { get; set; }

    public int Y { get; set; }
}

Create 2 instances:

var p1 = new Point { X = 5, Y = 10 };
var p2 = new Point { X = 7, Y = 3 };

Now, you want to output it to the screen. The 2 ways that you usually use:

Console.WriteLine("The area of interest is bounded by (" + p1.X + "," + p1.Y + ") and (" + p2.X + "," + p2.Y + ")");

As you can see, concatenating string like this makes the code hard to read and error-prone. You may use string.Format() to make it nicer:

Console.WriteLine(string.Format("The area of interest is bounded by({0},{1}) and ({2},{3})", p1.X, p1.Y, p2.X, p2.Y));

This creates a new problem:

1. You have to maintain the number of arguments and index yourself. If the number of arguments and index are not the same, it will generate a runtime error.

For those reasons, we should use new feature:

Console.WriteLine($"The area of interest is bounded by ({p1.X},{p1.Y}) and ({p2.X},{p2.Y})");

The compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

For the full post, please read this blog.

Change the folder "jdk1.7.0_45" "jdk1_7_0_60" and update the path in Windows environment. Otherwise, the path ignores the dot at the front which stands for hidden file and so the folder is not displayed in PATH strings.

If you use Mac, you are in luck. One can change the keymap for Intellij as Mac OS X, then you can use option+C.

It's not only a Python bug with * actually, it can also happen when you pass a string as a part of your regular expression to be compiled, like ;

import re
input_line = "string from any input source"
processed_line= "text to be edited with {}".format(input_line)
target = "text to be searched"
re.search(processed_line, target)

this will cause an error if processed line contained some "(+)" for example, like you can find in chemical formulae, or such chains of characters. the solution is to escape but when you do it on the fly, it can happen that you fail to do it properly...

Its simple, just make sure the data type in your columns are the same. For e.g. I faced the same error, that and an another error:

Error in contrasts<-(*tmp*, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels

So, I went back to my excel file or csv file, set a filter on the variable throwing me an error and checked if the distinct datatypes are the same. And... Oh! it had numbers and strings, so I converted numbers to string and it worked just fine for me.

In my situation, --prefix= failed to update the path correctly under some warnings or failures. please see the below link for the answer. https://stackoverflow.com/a/50208379/1283198

you need to join the two tables:

for instance you want to copy the value of name from tableA into tableB where they have the same ID

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.id = t2.id
SET t1.name = t2.name 
WHERE t2.name = 'Joe'

UPDATE 1

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.id = t2.id
SET t1.name = t2.name 

UPDATE 2

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.name = t2.name
SET t1.value = t2.value

The error you're seeing is that CMake cannot find a FindOpenCV.cmake file, because cmake doesn't include one out of the box. Therefore you need to find one and put it where cmake can find it:

You can find a good start here. If you're feeling adventurous you can also write your own.

Then add it somewhere in your project and adjust CMAKE_MODULE_PATH so that cmake can find it.

e.g., if you have

CMakeLists.txt
cmake-modules/FindOpenCV.cmake

Then you should do a

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_CURRENT_SOURCE_DIR}/cmake-modules)

In your CMakeLists.txt file before you do a find_package(OpenCV)

I'm lacking context, but this is working just fine:

List<BigInteger> nums = new ArrayList<BigInteger>();
Long max = Collections.max(nums).longValue(); // from BigInteger to Long...

Remove the display:none, and use ng-show instead:

<ul class="procedures">
    <li ng-repeat="procedure in procedures | filter:query | orderBy:orderProp">
        <h4><a href="#" ng-click="showDetails = ! showDetails">{{procedure.definition}}</a></h4>
         <div class="procedure-details" ng-show="showDetails">
            <p>Number of patient discharges: {{procedure.discharges}}</p>
            <p>Average amount covered by Medicare: {{procedure.covered}}</p>
            <p>Average total payments: {{procedure.payments}}</p>
         </div>
    </li>
</ul>

Here's the fiddle: http://jsfiddle.net/asmKj/

You can also use ng-class to toggle a class:

<div class="procedure-details" ng-class="{ 'hidden': ! showDetails }">

I like this more, since it allows you to do some nice transitions: http://jsfiddle.net/asmKj/1/

Go to iOS Simulator-> Hardware-> Keyboard -> Uncheck the Connect Hardware Keyboard Option. This will fix the issue.

i do this

//Restart the timer
queueTimer.Enabled = true;

I found this method to be quite useful. However it will convert your date/time format to just date but never the less it does the job for what I need it for. (I just needed to display the date on a report, the time was irrelevant).

CAST(start_date AS DATE)

UPDATE

(Bear in mind I'm a trainee ;))

I figured an easier way to do this IF YOU'RE USING SSRS.

It's easier to actually change the textbox properties where the field is located in the report. Right click field>Number>Date and select the appropriate format!

strtotime(), as in date("F j, Y", strtotime("yesterday"));

Nothing worked for me on my linux hosting. The only possible commands they provide are:

/usr/local/bin/php absolute/path/to/cron/script

and

/usr/local/bin/ea-php56 absolute/domain_path/path/to/cron/script 

This is how I made it to work: 1. I created simple test.php file with the following content:

2. I set the cronjob with the option server gived me using absolute inner path :)

The com.recoyxgroup.javascript.enum package allows you to properly define enum and flags enum classes, where:

• Every constant is represented as an immutable { _value: someNumber }
• Every constant has a property attached to the enum class (E.CONSTANT_NAME)
• Every constant has a friendly String (constantName)
• Every constant has a Number (someNumber)
• You can declare custom properties/methods using E.prototype.

Wherever a specific enum is expected, the convention is to do E(v), like this:

const { FlagsEnum } from 'com.recoyxgroup.javascript.enum';

const Rights = FlagsEnum('Rights', [
    'ADMINISTRATION',
    'REVIEW',
]);

function fn(rights) {
    rights = Rights(rights);
    console.log('administration' in rights, 'review' in rights);
}

fn( ['administration', 'review'] ); // true true
fn( 'administration' ); // true false
fn( undefined ); // false false

var r = Rights.ADMINISTRATION;
console.log( r == 'administration' );

As you can see, you can still compare the value to a String.

Definitions can be more specific:

const E = FlagsEnum('E', [
    ['Q', 0x10],
    ['K', 'someB'],
    ['L', [0x40, 'someL']],
]);

FlagsEnum products > Instance properties/methods

• number (was going to be valueOf(), but because of JS ==, had to be 'number')
• set()
• exclude()
• toggle()
• filter()
• valueOf()
• toString()

Try to give the full path to your csv file

open('/users/gcameron/Desktop/map/data.csv')

The python process is looking for file in the directory it is running from.

You have set #slider as absolute, which means that it "is positioned relative to the nearest positioned ancestor" (confusing, right?). Meanwhile, #content div is placed relative, which means "relative to its normal position". So the position of the 2 divs is not related.

You can read about CSS positioning here

If you set both to relative, the divs will be one after the other, as shown here:

#slider {
    position:relative;
    left:0;
    height:400px;

    border-style:solid;
    border-width:5px;
}
#slider img {
    width:100%;
}

#content {
    position:relative;
}

#content #text {
    position:relative;
    width:950px;
    height:215px;
    color:red;
}

IMO, froadie's simple concatenation is fine for a simple case like you presented. If you want to put together several strings, the string join method seems to be preferred:

the_text = ''.join(['the ', 'quick ', 'brown ', 'fox ', 'jumped ', 'over ', 'the ', 'lazy ', 'dog.'])

Edit: Note that join wants an iterable (e.g. a list) as its single argument.

Look at PrinterSettings.InstalledPrinters

This will do the trick :-

new Date().valueOf() 

mkdir -p

-p, --parents no error if existing, make parent directories as needed

If you have another array of char, char[] b and you want to replace c with b, you can use c=b.clone();.

os.Mkdir is used to create a single directory. To create a folder path, instead try using:

os.MkdirAll(folderPath, os.ModePerm)

Go documentation

func MkdirAll(path string, perm FileMode) error

MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error. The permission bits perm are used for all directories that MkdirAll creates. If path is already a directory, MkdirAll does nothing and returns nil.

Edit:

Updated to correctly use os.ModePerm instead.
For concatenation of file paths, use package path/filepath as described in @Chris' answer.

Look at git stash to put all of your local changes into a "stash file" and revert to the last commit. At that point, you can apply your stashed changes, or discard them.

This looks a little better than your previous version but get rid of that .Activate on that line and see if you still get that error.

Dim sh1 As Worksheet
set sh1 = Workbooks.Add(filenum(lngPosition) & ".csv")

Creates a worksheet object. Not until you create that object do you want to start working with it. Once you have that object you can do the following:

sh1.Range("A69").Paste
sh1.Range("A69").Select

The sh1. explicitely tells Excel which object you are saying to work with... otherwise if you start selecting other worksheets while this code is running you could wind up pasting data to the wrong place.

try

hive --outputformat==csv2 -e "select * from YOUR_TABLE";

I guess I will start you off with the time complexity of a linked list:

Indexing---->O(n)
Inserting / Deleting at end---->O(1) or O(n)
Inserting / Deleting in middle--->O(1) with iterator O(n) with out

The time complexity for the Inserting at the end depends if you have the location of the last node, if you do, it would be O(1) other wise you will have to search through the linked list and the time complexity would jump to O(n).

Yes. Regardless of what anyone else says, Eclipse contains some bug(s) that sometimes causes the workspace setting (e.g. 1.6 compliant) to be ignored. This is even when the per-project settings are disabled, the workspace settings are correct (1.6), the JRE is correctly set, there is only a 1.6 JRE defined, etc., all the things that people generally recommend when questions about this issue are posted to various forums (as they often are).

We hit this irregularly, but often, and typically when there is some unrelated issue with build-time dependencies or other project issues. It seems to fall into the general category of "unable to get Eclipse to recognize reality" issues that I always attribute, rightly or wrongly, to refresh issues with Eclipse' extensive metadata. Eclipse metadata is a blessing and a curse; when all is working well, it makes the tool exceedingly powerful and fast. But when there are problems, the extensive caching makes straightening out the issues more difficult - sometimes much more difficult - than with other tools.

I'd use a set myself, but here's yet another way:

uniquewords = []
while True:
    ipta = raw_input("Word: ")
    if ipta == "":
        break
    if not ipta in uniquewords:
        uniquewords.append(ipta)
print "There are", len(uniquewords), "unique words!"

EDIT: It seems I was wrong about the performance on the code example. The best performer is whichever snippet runs second in the posted case. This demonstrates what I was trying to explain, and the time differences are not as dramatic:

Although the temp table in the code below has no index, the performance is still enhanced by the fact that a comparison is done between an expression and a value in the table and not an expression that modifies the value in the table and a constant. Hope this is found to be useful.

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

As we know jQuery validate plugin invalidates Select field when it has blank value. Why don't we set its value to blank when required.

Yes, you can validate select field with some predefined value.

$("#everything").validate({
    rules: {
        select_field:{
            required: {
                depends: function(element){
                    if('none' == $('#select_field').val()){
                        //Set predefined value to blank.
                        $('#select_field').val('');
                    }
                    return true;
                }
            }
        }
    }
});

We can set blank value for select field but in some case we can't. For Ex: using a function that generates Dropdown field for you and you don't have control over it.

I hope it helps as it helps me.

Give this a try :P

s = '#'.repeat(10)_x000D_
_x000D_
document.body.innerHTML = s

It sounds like you'd be happer with a single table. The five having the same schema, and sometimes needing to be presented as if they came from one table point to putting it all in one table.

Add a new column which can be used to distinguish among the five languages (I'm assuming it's language that is different among the tables since you said it was for localization). Don't worry about having 4.5 million records. Any real database can handle that size no problem. Add the correct indexes, and you'll have no trouble dealing with them as a single table.

Yes it is true.

If you create two instance of your class

Test t1 = new Test();
Test t2 = new Test();

Then t1.foo and t2.foo both synchronize on the same static object and hence block each other.

Just apply scroll behaviour to all elements with this one-line code:

*{
scroll-behavior: smooth !important;
}

In my case it was entirely my fault (as usual) I was changing the system path under the environment variables, in Windows, and messed up the path for Node/NPM. So the solution is to either re-add the path for NPM, see this answer or the lazy option: re-install it which will re-add it for you.

If you're using Xamarin, I found a guide on their official forum explaining how to do this:

1. Download the package from the internet. There are many sources for this, one possible source is the CyanogenMod web site.
2. Start up the Android Player and unlock it.
3. Drag and drop the zip file that you downloaded onto the Android Player.
4. Restart the Android Player.

Hereafter, you might also need to update the Google Play Services from the Google Play Store.

Hope this helps for anyone else who has troubles finding the documentation.

Let me make a conclusion. In Swift 5

You can choose to addSubview to keyWindow, if you add the view in the last. Otherwise, you can bringSubViewToFront.

let view = UIView()
UIApplication.shared.keyWindow?.addSubview(view)
UIApplication.shared.keyWindow?.bringSubviewToFront(view)

You can also set the zPosition. But the drawback is that you can not change the gesture responding order.

view.layer.zPosition = 1

this code will help you, in that there is two button one for Camera and another for Gallery, and Image will be displayed in ImageView

https://github.com/siddhpuraamitr/Choose-Image-From-Gallery-Or-Camera

Try this code. You get android device name.

public static String getDeviceName() {
    String manufacturer = Build.MANUFACTURER;
    String model = Build.MODEL;
    if (model.startsWith(manufacturer)) {
        return model;
    }
    return manufacturer + " " + model;
}

You have two choices, depending on your table order

create table aa (sht int)
create table cc (sht int)
create table cd (sht int)
create table ab (sht int)

-- type 1    
select * from cd
inner join cc on cd.sht = cc.sht
LEFT JOIN ab ON ab.sht = cd.sht
LEFT JOIN aa ON aa.sht = cc.sht

-- type 2
select * from cc
inner join cc on cd.sht = cc.sht
LEFT JOIN ab
LEFT JOIN aa
ON aa.sht = ab.sht
ON ab.sht = cd.sht

You can use the terms aggregation.

{
"size": 0,
"aggs" : {
    "langs" : {
        "terms" : { "field" : "language",  "size" : 500 }
    }
}}

The size parameter within the aggregation specifies the maximum number of terms to include in the aggregation result. If you need all results, set this to a value that is larger than the number of unique terms in your data.

A search will return something like:

{
"took" : 16,
"timed_out" : false,
"_shards" : {
  "total" : 2,
  "successful" : 2,
  "failed" : 0
},
"hits" : {
"total" : 1000000,
"max_score" : 0.0,
"hits" : [ ]
},
"aggregations" : {
  "langs" : {
    "buckets" : [ {
      "key" : "10",
      "doc_count" : 244812
    }, {
      "key" : "11",
      "doc_count" : 136794
 
    }, {
      "key" : "12",
      "doc_count" : 32312
       } ]
    }
  }
}

It does seem odd. I found this thread, also thinking I'd seen one in the past, but couldn't find it in Javadoc.

I can see the Java developers' point about using specialised classes, and that the presence of a generic Pair class could cause developers to be lazy (perish the thought!)

However, in my experience, there are undoubtedly times when the thing you're modelling really is just a pair of things and coming up with a meaningful name for the relationship between the two halves of the pair, is actually more painful than just getting on with it. So instead, we're left to create a 'bespoke' class of practically boiler-plate code - probably called 'Pair'.

This could be a slippery slope, but a Pair and a Triplet class would cover a very large proportion of the use-cases.

If using Vagrant try reloading your box. This solved my issue.

Yes.

Add DisableCacheViewer Registry Key

Create a new dword key under HKLM\Software\Microsoft\Fusion\ with the name DisableCacheViewer and set it’s [DWORD] value to 1.

Go back to Windows Explorer to the assembly folder and it will be the normal file system view.

• DTR - Data Terminal Ready
• DSR - Data Set Ready
• RTS - Request To Send
• CTS - Clear To Send

There are multiple ways of doing things because there were never any protocols built into the standards. You use whatever ad-hoc "standard" your equipment implements.

Just based on the names, RTS/CTS would seem to be a natural fit. However, it's backwards from the needs that developed over time. These signals were created at a time when a terminal would batch-send a screen full of data, but the receiver might not be ready, thus the need for flow control. Later the problem would be reversed, as the terminal couldn't keep up with data coming from the host, but the RTS/CTS signals go the wrong direction - the interface isn't orthogonal, and there's no corresponding signals going the other way. Equipment makers adapted as best they could, including using the DTR and DSR signals.

EDIT

To add a bit more detail, its a two level hierarchy so "officially" both must happen for communication to take place. The behavior is defined in the original CCITT (now ITU-T) standard V.28.

The DCE is a modem connecting between the terminal and telephone network. In the telephone network was another piece of equipment which split off to the data network, eg. X.25.

The modem has three states: Powered off, Ready (Data Set Ready is true), and connected (Data Carrier Detect)

The terminal can't do anything until the modem is connected.

When the modem wants to send data, it raises RTS and the modem grants the request with CTS. The modem lowers CTS when its internal buffer is full.

So nostalgic!

jot would work too (in bash shell)

for i in `jot 1000 1`; do echo "http://example.com/$i.jpg"; done

As the thread mentioned in the comment, get-command in powershell can also work it out. For example, you can type get-command npm and the output is as below:

I have the same error, please go to

xampp\phpMyAdmin\libraries\config.default.php

Look for : $cfg['ExecTimeLimit'] = 600;

You can change '600' to any higher value, like '6000'.

Maximum execution time in seconds is (0 for no limit).

This will fix your error.

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

This function checks if it's input is numeric in the classical sense, as one expects a normal number detection function to work.

It's a test one can use for HTML form input, for example.

It bypasses all the JS folklore, like tipeof(NaN) = number, parseint('1 Kg') = 1, booleans coerced into numbers, and the like.

It does it by rendering the argument as a string and checking that string against a regex like those by @codename- but allowing entries like 5. and .5

function isANumber( n ) {
    var numStr = /^-?(\d+\.?\d*)$|(\d*\.?\d+)$/;
    return numStr.test( n.toString() );
}

not numeric:
Logger.log( 'isANumber( "aaa" ): ' + isANumber( 'aaa' ) );
Logger.log( 'isANumber( "" ): ' + isANumber( '' ) );
Logger.log( 'isANumber( "lkjh" ): ' + isANumber( 'lkjh' ) );
Logger.log( 'isANumber( 0/0 ): ' + isANumber( 0 / 0 ) );
Logger.log( 'isANumber( 1/0 ): ' + isANumber( 1 / 0 ) );
Logger.log( 'isANumber( "1Kg" ): ' + isANumber( '1Kg' ) );
Logger.log( 'isANumber( "1 Kg" ): ' + isANumber( '1 Kg' ) );
Logger.log( 'isANumber( false ): ' + isANumber( false ) );
Logger.log( 'isANumber( true ): ' + isANumber( true ) );

numeric:
Logger.log( 'isANumber( "0" ): ' + isANumber( '0' ) );
Logger.log( 'isANumber( "12.5" ): ' + isANumber( '12.5' ) );
Logger.log( 'isANumber( ".5" ): ' + isANumber( '.5' ) );
Logger.log( 'isANumber( "5." ): ' + isANumber( '5.' ) );
Logger.log( 'isANumber( "-5" ): ' + isANumber( '-5' ) );
Logger.log( 'isANumber( "-5." ): ' + isANumber( '-5.' ) );
Logger.log( 'isANumber( "-.5" ): ' + isANumber( '-5.' ) );
Logger.log( 'isANumber( "1234567890" ): ' + isANumber( '1234567890' ));

Explanation of the regex:

/^-?(\d+\.?\d*)$|(\d*\.?\d+)$/  

The initial "^" and the final "$" match the start and the end of the string, to ensure the check spans the whole string. The "-?" part is the minus sign with the "?" multiplier that allows zero or one instance of it.

Then there are two similar groups, delimited by parenthesis. The string has to match either of these groups. The first matches numbers like 5. and the second .5

The first group is

\d+\.?\d*

The "\d+" matches a digit (\d) one or more times.
The "\.?" is the decimal point (escaped with "\" to devoid it of its magic), zero or one times.

The last part "\d*" is again a digit, zero or more times.
All the parts are optional but the first digit, so this group matches numbers like 5. and not .5 which are matched by the other half.

As m.edmondson mentioned, "The remote host closed the connection." occurs when a user or browser cancels something, or the network connection drops etc. It doesn't necessarily have to be a file download however, just any request for any resource that results in a response to the client. Basically the error means that the response could not be sent because the server can no longer talk to the client(browser).

There are a number of steps that you can take in order to stop it happening. If you are manually sending something in the response with a Response.Write, Response.Flush, returning data from a web servivce/page method or something similar, then you should consider checking Response.IsClientConnected before sending the response. Also, if the response is likely to take a long time or a lot of server-side processing is required, you should check this periodically until the response.end if called. See the following for details on this property:

http://msdn.microsoft.com/en-us/library/system.web.httpresponse.isclientconnected.aspx

Alternatively, which I believe is most likely in your case, the error is being caused by something inside the framework. The following link may by of use:

The most important distinction is that DateTime does not store time zone information, while DateTimeOffset does.

Although DateTime distinguishes between UTC and Local, there is absolutely no explicit time zone offset associated with it. If you do any kind of serialization or conversion, the server's time zone is going to be used. Even if you manually create a local time by adding minutes to offset a UTC time, you can still get bit in the serialization step, because (due to lack of any explicit offset in DateTime) it will use the server's time zone offset.

For example, if you serialize a DateTime value with Kind=Local using Json.Net and an ISO date format, you'll get a string like 2015-08-05T07:00:00-04. Notice that last part (-04) had nothing to do with your DateTime or any offset you used to calculate it... it's just purely the server's time zone offset.

Meanwhile, DateTimeOffset explicitly includes the offset. It may not include the name of the time zone, but at least it includes the offset, and if you serialize it, you're going to get the explicitly included offset in your value instead of whatever the server's local time happens to be.

With boost you can use any_of_equal:

#include <boost/algorithm/cxx11/any_of.hpp>

bool item_present = boost::algorithm::any_of_equal(vector, element);

Step 1: first we have to add permissions in manifest file like

<uses-permission android:name="android.permission.RECEIVE_SMS" android:protectionLevel="signature" />
<uses-permission android:name="android.permission.READ_SMS" />

Step 2: then add service sms receiver class for receiving sms

<receiver android:name="com.aquadeals.seller.services.SmsReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
    </intent-filter>
</receiver>

Step 3: Add run time permission

private boolean checkAndRequestPermissions()
{
    int sms = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS);

    if (sms != PackageManager.PERMISSION_GRANTED)
    {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

Step 4: Add this classes in your app and test Interface class

public interface SmsListener {
   public void messageReceived(String messageText);
}

SmsReceiver.java

public class SmsReceiver extends BroadcastReceiver {
    private static SmsListener mListener;
    public Pattern p = Pattern.compile("(|^)\\d{6}");
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle data  = intent.getExtras();
        Object[] pdus = (Object[]) data.get("pdus");
        for(int i=0;i<pdus.length;i++)
        {
            SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
            String sender = smsMessage.getDisplayOriginatingAddress();
            String phoneNumber = smsMessage.getDisplayOriginatingAddress();
            String senderNum = phoneNumber ;
            String messageBody = smsMessage.getMessageBody();
            try{
                if(messageBody!=null){
                    Matcher m = p.matcher(messageBody);
                    if(m.find()) {
                        mListener.messageReceived(m.group(0));
                    }
                }
            }
            catch(Exception e){}
        }
    }
    public static void bindListener(SmsListener listener) {
        mListener = listener; 
    }
}

If you're doing it via CMD as you say, then you can just enter the command like so:

path\to\your.exe 

which will open it within the same window. For example in C++:

system("path\\to\\your.exe"); // Double backslash for escaping

will open your.exe in the current CMD window. Likewise to start with a new window, just go for:

system("start path\\to\\your.exe");

If you go for the first option, you would have to clear your screen unless you wanted to have the command to open your.exe on the screen still.

You can use the following code to check if a textbox object is null/empty

'Checks if the box is null

If Me.TextBox & "" <> "" Then

        'Enter Code here...

End if

Try

set wildmenu
set wildmode=list:full
set wildcharm=<C-z>
let mapleader=','
nnoremap <leader>c :colorscheme <C-z><S-Tab>

in your ~/.vimrc.

The first two lines make possible matches appear as lists. You can use either or both.

The fourth line makes leader , instead of the default \.

The last line allows you to simply type ,c to get a list and a prompt to change your colorscheme.

The third line effectively allows for Tabs to appear in key maps.

(Of course, all of these strategies I've learned from the internet, and mostly SO, very recently.)

Yes you can do that.

Here is an example:

a{
    background:IMAGE-URL;
    display:block;
    height:IMAGE-HEIGHT;
    width:IMAGE-WIDTH;
}

Of course you can modify the above example to your need. The important thing is to make it appear as a block (display:block) or an inline block (display:inline-block).

What worked for me was

<WebBrowser Source="pack://siteoforigin:,,,/StartPage.html" />

from here. I copied StartPage.html to the same output directory as the xaml-file and it loaded it from that relative path.

Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)

Additionally, it could be handy to know:

This question is the first one that shows up on Google when one looks up "Python how to add elements to set", so it's worth noting explicitly that, if you want to add a whole string to a set, it should be added with .add(), not .update().

Say you have a string foo_str whose contents are 'this is a sentence', and you have some set bar_set equal to set().

If you do bar_set.update(foo_str), the contents of your set will be {'t', 'a', ' ', 'e', 's', 'n', 'h', 'c', 'i'}.

If you do bar_set.add(foo_str), the contents of your set will be {'this is a sentence'}.

There is no command in Git that will do this for you automatically. But you can write a script that uses Git commands to give you what you need. This could be done in many ways depending on what branching model you are using.

If you need to know if a branch has been merged into master the following command will yield no output if myTopicBranch has been merged (i.e. you can delete it)

$ git rev-list master | grep $(git rev-parse myTopicBranch)

You could use the Git branch command and parse out all branches in Bash and do a for loop over all branches. In this loop you check with above command if you can delete the branch or not.

As the OP does understand the problem, just looks for a nicer solution...

How about this as a practice ?

• Have on actual feature-develop branch (where you never rebase and force-push, so your fellow feature developers don't hate you). Here, regularly grab those changes from main with a merge. Messier history, yes, but life is easy and no one get's interupted in his work.

• Have a second feature-develop branch, where one feature team member regulary pushes all feature commits to, indeed rebased, indeed forced. So almost cleanly based on a fairly recent master commit. Upon feature complete, push that branch on top of master.

There might be a pattern name for this method already.

If you are using python3.x then Run below command

pip install mysqlclient

Then change setting.py like

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'DB',
     'USER': 'username',
    'PASSWORD': 'passwd',
  }
  }

See this implementation from PEP318, implementing the singleton pattern with a decorator:

def singleton(cls):
    instances = {}
    def getinstance():
        if cls not in instances:
            instances[cls] = cls()
        return instances[cls]
    return getinstance

@singleton
class MyClass:
    ...

You can simply add the two.

• if the Time part of your Date column is always zero
• and the Date part of your Time column is also always zero (base date: January 1, 1900)

Adding them returns the correct result.

SELECT Combined = MyDate + MyTime FROM MyTable

Rationale (kudos to ErikE/dnolan)

It works like this due to the way the date is stored as two 4-byte Integers with the left 4-bytes being the date and the right 4-bytes being the time. Its like doing $0001 0000 + $0000 0001 = $0001 0001

Edit regarding new SQL Server 2008 types

Date and Time are types introduced in SQL Server 2008. If you insist on adding, you can use Combined = CAST(MyDate AS DATETIME) + CAST(MyTime AS DATETIME)

Edit2 regarding loss of precision in SQL Server 2008 and up (kudos to Martin Smith)

Have a look at How to combine date and time to datetime2 in SQL Server? to prevent loss of precision using SQL Server 2008 and up.

You may want to also look into using Task instead of background workers.

The easiest way to do this is in your example is Task.Run(InitializationThread);.

There are several benefits to using tasks instead of background workers. For example, the new async/await features in .net 4.5 use Task for threading. Here is some documentation about Task https://docs.microsoft.com/en-us/dotnet/api/system.threading.tasks.task

You need to use %2.6f instead of %f in your printf statement

We store our URLs in a database and load them at runtime.

public class ServiceClientFactory<TChannel> : ClientBase<TChannel> where TChannel : class
{
    public TChannel Create(string url)
    {
        this.Endpoint.Address = new EndpointAddress(new Uri(url));
        return this.Channel;
    }
}

Implementation

var client = new ServiceClientFactory<yourServiceChannelInterface>().Create(newUrl);

And to add to this answer, make sure the image itself has a transparent background.

You've already stated why np.maximum is different - it returns an array that is the element-wise maximum between two arrays.

As for np.amax and np.max: they both call the same function - np.max is just an alias for np.amax, and they compute the maximum of all elements in an array, or along an axis of an array.

In [1]: import numpy as np

In [2]: np.amax
Out[2]: <function numpy.core.fromnumeric.amax>

In [3]: np.max
Out[3]: <function numpy.core.fromnumeric.amax>

My current solution solves most of the issues you mentioned yet its completely abstracted from platform specific things and can be reused. Also i used no code-behind only binding with DelegateCommands that implement ICommand. Dialog is basically a View - a separate control that has its own ViewModel and it is shown from the ViewModel of the main screen but triggered from the UI via DelagateCommand binding.

See full Silverlight 4 solution here Modal dialogs with MVVM and Silverlight 4

How about this:

List<String> definedOrder = // define your custom order
    Arrays.asList("Red", "Green", "Magenta", "Silver");

Comparator<Car> comparator = new Comparator<Car>(){

    @Override
    public int compare(final Car o1, final Car o2){
        // let your comparator look up your car's color in the custom order
        return Integer.valueOf(
            definedOrder.indexOf(o1.getColor()))
            .compareTo(
                Integer.valueOf(
                    definedOrder.indexOf(o2.getColor())));
    }
};

In principle, I agree that using an enum is an even better approach, but this version is more flexible as it lets you define different sort orders.

Update

Guava has this functionality baked into its Ordering class:

List<String> colorOrder = ImmutableList.of("red","green","blue","yellow");
final Ordering<String> colorOrdering = Ordering.explicit(colorOrder);
Comparator<Car> comp = new Comparator<Car>() {
    @Override
    public int compare(Car o1, Car o2) {
        return colorOrdering.compare(o1.getColor(),o2.getColor());
    }
}; 

This version is a bit less verbose.

Update again

Java 8 makes the Comparator even less verbose:

Comparator<Car> carComparator = Comparator.comparing(
        c -> definedOrder.indexOf(c.getColor()));

Nope, no difference. It's just syntactic sugar. Arrays.asList(..) creates an additional list.

My Solution for this problem not using any STL methods but only C++ string's own methods is as following:

void processString(string &s) {
    if ( s.empty() ) return;

    //delete leading and trailing spaces of the input string
    int notSpaceStartPos = 0, notSpaceEndPos = s.length() - 1;
    while ( s[notSpaceStartPos] == ' ' ) ++notSpaceStartPos;
    while ( s[notSpaceEndPos] == ' ' ) --notSpaceEndPos;
    if ( notSpaceStartPos > notSpaceEndPos ) { s = ""; return; }
    s = s.substr(notSpaceStartPos, notSpaceEndPos - notSpaceStartPos + 1);

    //reduce multiple spaces between two words to a single space 
    string temp;
    for ( int i = 0; i < s.length(); i++ ) {
        if ( i > 0 && s[i] == ' ' && s[i-1] == ' ' ) continue;
        temp.push_back(s[i]);
    }
    s = temp;
}

I have used this method to pass a LeetCode problem Reverse Words in a String

var defaultsettings = {
    ajaxsettings: {
        ...
    },
    uisettings: {
        ...

Is it acceptable & safe to run pip install under sudo?

It's not safe and it's being frowned upon – see What are the risks of running 'sudo pip'? To install Python package in your home directory you don't need root privileges. See description of --user option to pip.

In my scenario i have make this via below code in nginx vhost configuration

server {
server_name dashboards.etilize.com;

location / {
    proxy_pass http://demo.etilize.com/dashboards/;
    proxy_set_header Host $http_host;
}}

$http_host will set URL in Header same as requested

I have an implementation as part of a spreadsheet project.

This code is not yet tested thoroughly, but anyone is welcome to use it.

As some of the answers noted though, your implementation can be much simpler if you actually have DSV or TSV file, as they disallow the use of the record and field separators in the values. CSV, on the other hand, can actually have commas and newlines inside a field, which breaks most regular expression and split-based approaches.

var CSV = {
    parse: function(csv, reviver) {
        reviver = reviver || function(r, c, v) { return v; };
        var chars = csv.split(''), c = 0, cc = chars.length, start, end, table = [], row;
        while (c < cc) {
            table.push(row = []);
            while (c < cc && '\r' !== chars[c] && '\n' !== chars[c]) {
                start = end = c;
                if ('"' === chars[c]){
                    start = end = ++c;
                    while (c < cc) {
                        if ('"' === chars[c]) {
                            if ('"' !== chars[c+1]) {
                                break;
                            }
                            else {
                                chars[++c] = ''; // unescape ""
                            }
                        }
                        end = ++c;
                    }
                    if ('"' === chars[c]) {
                        ++c;
                    }
                    while (c < cc && '\r' !== chars[c] && '\n' !== chars[c] && ',' !== chars[c]) {

We can use useDebouncedCallback to perform this task in react.

import { useDebouncedCallback } from 'use-debounce'; - install npm packge for same if not installed

const [searchText, setSearchText] = useState('');

const onSearchTextChange = value => {
    setSearchText(value);
  };

//call search api
  const [debouncedOnSearch] = useDebouncedCallback(searchIssues, 500);
  useEffect(() => {
    debouncedOnSearch(searchText);
  }, [searchText, debouncedOnSearch]);

var = False
if not var: print 'learnt stuff'

Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.ENGLISH);
cal.setTime(sdf.parse("Mon Mar 14 16:02:37 GMT 2011"));// all done

note: set Locale according to your environment/requirement

Is there a way to set my property as null or string.empty in order to restablish the field in the database as null.

No. Because it's non-nullable. If you want it to be nullable, you have to use Nullable<Guid> - if you didn't, there'd be no point in having Nullable<T> to start with. You've got a fundamental issue here - which you actually know, given your first paragraph. You've said, "I know if I want to achieve A, I must do B - but I want to achieve A without doing B." That's impossible by definition.

The closest you can get is to use one specific GUID to stand in for a null value - Guid.Empty (also available as default(Guid) where appropriate, e.g. for the default value of an optional parameter) being the obvious candidate, but one you've rejected for unspecified reasons.

This is where jQuery really shines for ASP.Net developers. Lets say you have this ASP button:

When that renders, you can look at the source of the page and the id on it won't be btnAwesome, but $ctr001_btnAwesome or something like that. This makes it a pain in the butt to find in javascript. Enter jQuery.

$(document).ready(function() {
  $("input[id$='btnAwesome']").click(function() {
    // Do client side button click stuff here.
  });
});

The id$= is doing a regex match for an id ENDING with btnAwesome.

Edit:

Did you want the ajax call being called from the button click event on the client side? What did you want to call? There are a lot of really good articles on using jQuery to make ajax calls to ASP.Net code behind methods.

The gist of it is you create a static method marked with the WebMethod attribute. You then can make a call to it using jQuery by using $.ajax.

$.ajax({
  type: "POST",
  url: "PageName.aspx/MethodName",
  data: "{}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg) {
    // Do something interesting here.
  }
});

I learned my WebMethod stuff from: http://encosia.com/2008/05/29/using-jquery-to-directly-call-aspnet-ajax-page-methods/

A lot of really good ASP.Net/jQuery stuff there. Make sure you read up about why you have to use msg.d in the return on .Net 3.5 (maybe since 3.0) stuff.

There's a definite need to get the last element of a dictionary, for example to confirm whether the latest element has been appended to the dictionary object or not.

We need to convert the dictionary keys to a list object, and use an index of -1 to print out the last element.

mydict = {'John':'apple','Mat':'orange','Jane':'guava','Kim':'apple','Kate': 'grapes'}

mydict.keys()

output: dict_keys(['John', 'Mat', 'Jane', 'Kim', 'Kate'])

list(mydict.keys())

output: ['John', 'Mat', 'Jane', 'Kim', 'Kate']

list(mydict.keys())[-1]

output: 'Kate'

To quote the documentation:

Key words and unquoted identifiers are case insensitive. Therefore:

UPDATE MY_TABLE SET A = 5;

can equivalently be written as:

uPDaTE my_TabLE SeT a = 5;

You could also write it using quoted identifiers:

UPDATE "my_table" SET "a" = 5;

Quoting an identifier makes it case-sensitive, whereas unquoted names are always folded to lower case (unlike the SQL standard where unquoted names are folded to upper case). For example, the identifiers FOO, foo, and "foo" are considered the same by PostgreSQL, but "Foo" and "FOO" are different from these three and each other.

If you want to write portable applications you are advised to always quote a particular name or never quote it.

Always try to log in using those credentials with SQL Management Studio. This might reveal some more details that you don't get at runtime in your code. I had checked the SQL + Windows authentication, restarted the server but still no luck. After trying to log in using SQL Management, I got this prompt:

Somehow the password had expired although the login was created just minutes before. Anyway, new password set, connection string updated and all's fine.

Just in case anyone hits the same problem whilst using WPF (rather than WCF or Silverlight):

I had this error, when connecting to a Web Service. When my code was in the "main" WPF Application solution, no problem, it worked perfectly. But when I moved the code to the more sensible DAL-layer solution, it would throw the exception.

Could not find default endpoint element that references contract 'MyWebService.MyServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

As has been stated by "Sprite" in this thread, you need to manually copy the tag.

For WPF apps, this means copying the tag from the app.config in my DAL solution to the app.config in the main WPF Application solution.

remove android:showAsAction="never" from res/menu folder from every xml file.

This very helpful feature is now available starting at version 1.1.2 of AngularJS. It's considered unstable but I have used it (1.1.3) and it works fine.

Basically you can use a function to generate a templateUrl string. The function is passed the route parameters that you can use to build and return the templateUrl string.

var app = angular.module('app',[]);

app.config(
    function($routeProvider) {
        $routeProvider.
            when('/', {templateUrl:'/home'}).
            when('/users/:user_id', 
                {   
                    controller:UserView, 
                    templateUrl: function(params){ return '/users/view/' + params.user_id; }
                }
            ).
            otherwise({redirectTo:'/'});
    }
);

Many thanks to https://github.com/lrlopez for the pull request.

None of the answers above worked for me, so I just gave my DIV tag a transparent background image instead, that worked perfectly for all browsers.

Use a negative lookahead and a negative lookbehind:

> s = "one two 3.4 5,6 seven.eight nine,ten"
> parts = re.split('\s|(?<!\d)[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten']

In other words, you always split by \s (whitespace), and only split by commas and periods if they are not followed (?!\d) or preceded (?<!\d) by a digit.

DEMO.

EDIT: As per @verdesmarald comment, you may want to use the following instead:

> s = "one two 3.4 5,6 seven.eight nine,ten,1.2,a,5"
> print re.split('\s|(?<!\d)[,.]|[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten', '1.2', 'a', '5']

This will split "1.2,a,5" into ["1.2", "a", "5"].

DEMO.

Just go on that directory of your JS file from cmd and write node jsFile.js or even node jsFile; both will work fine.

This method works for me well and I think the simplest way to do this is to use this javascript code inside the reloaded page's HTML.

if ( window.history.replaceState ) {_x000D_
  window.history.replaceState( null, null, window.location.href );_x000D_
}

To get the location of a script being sourced, you can use utils::getSrcDirectory or utils::getSrcFilename. So changing the working directory to that of the current file can be done with:

setwd(getSrcDirectory()[1])

This does not work in RStudio if you Run the code rather than Sourceing it. For that, you need to use rstudioapi::getActiveDocumentContext.

setwd(dirname(rstudioapi::getActiveDocumentContext()$path))

This second solution requires that you are using RStudio as your IDE, of course.

It may be late but there is a new simple solution to this question for who ever wants it.
In kotlin

val player = MediaPlayer.create(this,Settings.System.DEFAULT_RINGTONE_URI)
player.start()

Above code will play default ringtone but if you want default alarm, change

Settings.System.DEFAULT_RINGTONE_URI

to

Settings.System.DEFAULT_ALARM_ALERT_URI

on a CENTOS (Red Hat) virtual machine for svn server: edited /etc/init.d/svnserver to change the pid to something that svn can write:

pidfile=${PIDFILE-/home/svn/run/svnserve.pid}

and added option --user=svn:

daemon --pidfile=${pidfile} --user=svn $exec $args

The original pidfile was /var/run/svnserve.pid. The daemon did not start becaseu only root could write there.

 These all work:
/etc/init.d/svnserve start
/etc/init.d/svnserve stop
/etc/init.d/svnserve restart

With your question edit, I see your problem. Let's say the current directory is /home/yourname ... in this case, your command below:

sed 's/xxx/'$PWD'/'

will be expanded to

sed `s/xxx//home/yourname//

which is not valid. You need to put a \ character in front of each / in your $PWD if you want to do this.

Generally it means that you are providing an index for which a list element does not exist.

E.g, if your list was [1, 3, 5, 7], and you asked for the element at index 10, you would be well out of bounds and receive an error, as only elements 0 through 3 exist.

How about?

<?php
   $queried_post = get_page_by_path('my_slug',OBJECT,'post');
?>

You can either create a new Stage, add your controls into it or if you require the POPUP as Dialog box, then you may consider using DialogsFX or ControlsFX(Requires JavaFX8)

For creating a new Stage, you can use the following snippet

@Override
public void start(final Stage primaryStage) {
    Button btn = new Button();
    btn.setText("Open Dialog");
    btn.setOnAction(
        new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent event) {
                final Stage dialog = new Stage();
                dialog.initModality(Modality.APPLICATION_MODAL);
                dialog.initOwner(primaryStage);
                VBox dialogVbox = new VBox(20);
                dialogVbox.getChildren().add(new Text("This is a Dialog"));
                Scene dialogScene = new Scene(dialogVbox, 300, 200);
                dialog.setScene(dialogScene);
                dialog.show();
            }
         });
    }

If you don't want it to be modal (block other windows), use:

dialog.initModality(Modality.NONE);

set display:none for all other elements which are not for prints. setting visibility:hidden will keep them hidden, but they all are still there and have taken space for them. empty page is for those hidden elements.

Run the following commands in guest machine/VM:

wget https://raw.githubusercontent.com/mitchellh/vagrant/master/keys/vagrant.pub -O ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
chown -R vagrant:vagrant ~/.ssh

Then do vagrant halt. This will remove and regenerate your private keys.

(These steps assume you have already created or already have the ~/.ssh/ and ~/.ssh/authorized_keys directories under your home folder.)

What we have in our table:-

Primary Key
Event type (e.g. "UPDATED", "APPROVED")
Description ("Frisbar was added to blong")
User Id
User Id of second authoriser
Amount
Date/time
Generic Id
Table Name

The generic id points at a row in the table that was updated and the table name is the name of that table as a string. Not a good DB design, but very usable. All our tables have a single surrogate key column so this works well.

For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015 and run the program in the search result.
You can now execute your command in it, for example: cl /?

$a = 'John' ; <br/>
$b = 'Doe' ; <br/>
$c = $a.$b"&lt;br/>";

There's no need for Prototype here: JavaScript has for..in loops. If you're not sure that no one messed with Object.prototype, check hasOwnProperty() as well, ie

for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
        doSomethingWith(obj[prop]);
}

Just Javascript (as requested)

Add this function somewhere on your page (preferably in the <head>)

function clearBox(elementID)
{
    document.getElementById(elementID).innerHTML = "";
}

Then add the button on click event:

<button onclick="clearBox('cart_item')" />

In JQuery (for reference)

If you prefer JQuery you could do:

$("#cart_item").html("");

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO

Try this instead:

url = 'http://myserver/post_service'
data = urllib.urlencode({'name' : 'joe',
                         'age'  : '10'})
req = urllib2.Request(url=url,data=data)
content = urllib2.urlopen(req).read()
print content

For JSON data, it's much easier to POST it as "application/json" content-type. If you use GET, you have to URL-encode the JSON in a parameter and it's kind of messy. Also, there is no size limit when you do POST. GET's size if very limited (4K at most).

Try figsize param in df.plot(figsize=(width,height)):

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(3,3));

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(5,3));

The size in figsize=(5,3) is given in inches per (width, height)
