I had same problem. It was resolved by running same code in Administrator Console.

Use xpath more directly for both performance and clarity.

time_path <- "//start-valid-time"
temp_path <- "//temperature[@type='hourly']/value"

df <- data.frame(
    latitude=data[["number(//point/@latitude)"]],
    longitude=data[["number(//point/@longitude)"]],
    start_valid_time=sapply(data[time_path], xmlValue),
    hourly_temperature=as.integer(sapply(data[temp_path], as, "integer"))

leading to

> head(df, 2)
  latitude longitude          start_valid_time hourly_temperature
1    29.81    -82.42 2014-02-14T18:00:00-05:00                 60
2    29.81    -82.42 2014-02-14T19:00:00-05:00                 55

timer.cancel();  //Terminates this timer,discarding any currently scheduled tasks.

timer.purge();   // Removes all cancelled tasks from this timer's task queue.

Use Form, not form. The capitalization counts.

If you are on windows and using mingw, gcc uses the win32 runtime, where printf needs %I64d for a 64 bit integer. (and %I64u for an unsinged 64 bit integer)

For most other platforms you'd use %lld for printing a long long. (and %llu if it's unsigned). This is standarized in C99.

gcc doesn't come with a full C runtime, it defers to the platform it's running on - so the general case is that you need to consult the documentation for your particular platform - independent of gcc.

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

Try something like this

var d = new Date,
    dformat = [d.getMonth()+1,
               d.getDate(),
               d.getFullYear()].join('/')+' '+
              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');

If you want leading zero's for values < 10, use this number extension

Number.prototype.padLeft = function(base,chr){
    var  len = (String(base || 10).length - String(this).length)+1;
    return len > 0? new Array(len).join(chr || '0')+this : this;
}
// usage
//=> 3..padLeft() => '03'
//=> 3..padLeft(100,'-') => '--3' 

Applied to the previous code:

var d = new Date,
    dformat = [(d.getMonth()+1).padLeft(),
               d.getDate().padLeft(),
               d.getFullYear()].join('/') +' ' +
              [d.getHours().padLeft(),
               d.getMinutes().padLeft(),
               d.getSeconds().padLeft()].join(':');
//=> dformat => '05/17/2012 10:52:21'

See this code in jsfiddle

[edit 2019] Using ES20xx, you can use a template literal and the new padStart string extension.

var dt = new Date();_x000D_
_x000D_
console.log(`${_x000D_
    (dt.getMonth()+1).toString().padStart(2, '0')}/${_x000D_
    dt.getDate().toString().padStart(2, '0')}/${_x000D_
    dt.getFullYear().toString().padStart(4, '0')} ${_x000D_
    dt.getHours().toString().padStart(2, '0')}:${_x000D_
    dt.getMinutes().toString().padStart(2, '0')}:${_x000D_
    dt.getSeconds().toString().padStart(2, '0')}`_x000D_
);

I would like to make the case for SPA being best for Data Driven Applications. gmail, of course is all about data and thus a good candidate for a SPA.

But if your page is mostly for display, for example, a terms of service page, then a SPA is completely overkill.

I think the sweet spot is having a site with a mixture of both SPA and static/MVC style pages, depending on the particular page.

For example, on one site I am building, the user lands on a standard MVC index page. But then when they go to the actual application, then it calls up the SPA. Another advantage to this is that the load-time of the SPA is not on the home page, but on the app page. The load time being on the home page could be a distraction to first time site users.

This scenario is a little bit like using Flash. After a few years of experience, the number of Flash only sites dropped to near zero due to the load factor. But as a page component, it is still in use.

Here is complete library with the widget: https://github.com/opprime/EditTextField

To use it you should add the dependency:

compile 'com.optimus:editTextField:0.2.0'

In the layout.xml file you can play with the widget settings:

xmlns:app="http://schemas.android.com/apk/res-auto"

• app:clearButtonMode,can has such values: never always whileEditing unlessEditing

• app:clearButtonDrawable

Sample in action:

Just do:

List a = new ArrayList(); 
a.add("a"); 
a.add("b"); 
a.add("c"); 
List b = new ArrayList(a);

ArrayList has a constructor that will accept another Collection to copy the elements from

you have to split the datetime and then store it with your desired format like dd/MM/yyyy. then you can use this query with between but i have objection using this becasue it will search every single data on your database,so i suggest you can use datediff.

        Dim start = txtstartdate.Text.Trim()
        Dim endday = txtenddate.Text.Trim()
        Dim arr()
        arr = Split(start, "/")
        Dim dt As New DateTime
        dt = New Date(Val(arr(2).ToString), Val(arr(1).ToString), Val(arr(0).ToString))
        Dim arry()
        arry = Split(endday, "/")
        Dim dt2 As New DateTime
        dt2 = New Date(Val(arry(2).ToString), Val(arry(1).ToString), Val(arry(0).ToString))

        qry = "SELECT * FROM [calender] WHERE datediff(day,'" & dt & "',[date])>=0 and datediff(day,'" & dt2 & "',[date])<=0 "

here i have used dd/MM/yyyy format.

I am thinking about something else, if you are trying to login with a different username that doesn't exist this is the message you will get.

So I assume you may be trying to ssh with ec2-user but I recall recently most of centos AMIs for example are using centos user instead of ec2-user

so if you are ssh -i file.pem centos@public_IP please tell me you aretrying to ssh with the right user name otherwise this may be a strong reason of you see such error message even with the right permissions on your ~/.ssh/id_rsa or file.pem

In python 3 Tkinter renamed tkinter

I have been struggling with this myself, and I finally was able to track down the issue and what was causing it to fail.

It all stemmed from the fact that my login form was being dynamically injected into the page (using backbone.js). As soon as I embed my login form directly into my index.html file, everything worked like a charm.

I think this is because the browser has to be aware that there is an existing login form, but since mine was being dynamically injected into the page, it didn't know that a "real" login form ever existed.

I found out a crazy solution for dealing with this issue of checkbox not checked or checked here is my algorithm... create a global variable lets say var check_holder

check_holder has 3 states

1. undefined state
2. 0 state
3. 1 state

If the checkbox is clicked,

$(document).on("click","#check",function(){
    if(typeof(check_holder)=="undefined"){
          //this means that it is the first time and the check is going to be checked
          //do something
          check_holder=1; //indicates that the is checked,it is in checked state
    }
    else if(check_holder==1){
          //do something when the check is going to be unchecked
          check_holder=0; //it means that it is not checked,it is in unchecked state
    }
     else if(check_holder==0){
            //do something when the check is going to be checked
            check_holder=1;//indicates that it is in a checked state
     }
});

The code above can be used in many situation to find out if a checkbox has been checked or not checked. The concept behind it is to save the checkbox states in a variable, ie when it is on,off. i Hope the logic can be used to solve your problem.

Your delete code looks like this

Gridview1.DeleteRow(e.RowIndex);
Gridview1.DataBind();

When you call Gridview1.DataBind() you will populate your gridview with the current datasource. So, it will delete all the existent rows, and it will add all the rows from CustomersSqlDataSource.

What you need to do is delete the row from the table that CustomersSqlDataSource querying.

You can do this very easy by setting a delete command to CustomersSqlDataSource, add a delete parameter, and then execute the delete command.

CustomersSqlDataSource.DeleteCommand = "DELETE FROM Customer Where CustomerID=@CustomerID"; // Customer is the name of the table where you take your data from. Maybe you named it different 
CustomersSqlDataSource.DeleteParameters.Add("CustomerID", Gridview1.DataKeys[e.RowIndex].Values["CustomerID"].ToString());
CustomersSqlDataSource.Delete();
Gridview1.DataBind();

But take into account that this will delete the data from the database.

Thanks to João Paulo Oliveira, this was my solution which includes a variable (which was my goal).

document.getElementById( "myID" ).setAttribute( "onClick", "myFunction("+VALUE+");" );

Include this extension in your project

  extension String{
func trim() -> String
{
    return self.trimmingCharacters(in: NSCharacterSet.whitespaces)
}

var length: Int {
    return self.count
}

subscript (i: Int) -> String {
    return self[i ..< i + 1]
}

func substring(fromIndex: Int) -> String {
    return self[min(fromIndex, length) ..< length]
}

func substring(toIndex: Int) -> String {
    return self[0 ..< max(0, toIndex)]
}

subscript (r: Range<Int>) -> String {
    let range = Range(uncheckedBounds: (lower: max(0, min(length, r.lowerBound)),
                                        upper: min(length, max(0, r.upperBound))))
    let start = index(startIndex, offsetBy: range.lowerBound)
    let end = index(start, offsetBy: range.upperBound - range.lowerBound)
    return String(self[start ..< end])
}

func substring(fromIndex: Int, toIndex:Int)->String{
    let startIndex = self.index(self.startIndex, offsetBy: fromIndex)
    let endIndex = self.index(startIndex, offsetBy: toIndex-fromIndex)

    return String(self[startIndex...endIndex])
}

An then use the function like this

let str = "Sample-String"

let substring = str.substring(fromIndex: 0, toIndex: 0) //returns S
let sampleSubstr = str.substring(fromIndex: 0, toIndex: 5) //returns Sample

Date is not in any time zone (it is a millisecond office from a defined moment in time same for everyone), but underlying (R)DBs generally store timestamps in political format (year, month, day, hour, minute, second, ...) that is time-zone sensitive.

To be serious, Hibernate MUST be allow being told within some form of mapping that the DB date is in such-and-such timezone so that when it loads or stores it it does not assume its own...

You should try using the Grid Template.

Here's what I've used for a two Column Layout of a <ul>

<ul class="list-group row">
     <li class="list-group-item col-xs-6">Row1</li>
     <li class="list-group-item col-xs-6">Row2</li>
     <li class="list-group-item col-xs-6">Row3</li>
     <li class="list-group-item col-xs-6">Row4</li>
     <li class="list-group-item col-xs-6">Row5</li>
</ul>

This worked for me.

Adding to other answers already given above. If case insensivity is of any importance to you, then use Jackson. Gson does not support case insensitivity for key names, while jackson does.

Here are two related links

(No) Case sensitivity support in Gson : GSON: How to get a case insensitive element from Json?

select a.* , b.Aa , b.Ab, b.Ac from table1 a left join table2 b on a.id=b.id

this should select all columns from table 1 and only the listed columns from table 2 joined by id.

Reduce() is..

• The reduce() method reduces the array to a single value.
• The reduce() method executes a provided function for each value of the array (from left-to-right).
• The return value of the function is stored in an accumulator (result/total).

It was ..

let array=[1,2,3];
function sum(acc,val){ return acc+val;} // => can change to (acc,val)=>acc+val
let answer= array.reduce(sum); // answer is 6

Change to

let array=[1,2,3];
let answer=arrays.reduce((acc,val)=>acc+val);

Also you can use in

1. find max

    let array=[5,4,19,2,7];
    function findMax(acc,val)
    {
     if(val>acc){
       acc=val; 
     }
    }

    let biggest=arrays.reduce(findMax); // 19

2. find an element that not repeated.

    arr = [1, 2, 5, 4, 6, 8, 9, 2, 1, 4, 5, 8, 9]
    v = 0
    for i in range(len(arr)):
    v = v ^ arr[i]
    print(value)  //6

If your input file has a fixed amount of columns separated by commas and you know in which columns are the strings it might be best to use the function

textscan()

Note that you can specify a format where you read up to a maximum number of characters in the string or until a delimiter (comma) is found.

The System.Math.Round method uses the Double structure, which, as others have pointed out, is prone to floating point precision errors. The simple solution I found to this problem when I encountered it was to use the System.Decimal.Round method, which doesn't suffer from the same problem and doesn't require redifining your variables as decimals:

Decimal.Round(0.575, 2, MidpointRounding.AwayFromZero)

Result: 0.58

I've encountered a similar scenario. I solved it by adding in this following code just before find_library():

set(CMAKE_PREFIX_PATH /the/custom/path/to/your/lib/)

then it can find the library location.

I have found class<T> useful when I create service registry lookups. E.g.

<T> T getService(Class<T> serviceClass)

}

You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.

You can get the Java EE Edition of eclipse with has it pre-installed.

To create and run your first servlet:

1. New... Project... Dynamic Web Project.
2. Right click the project... New Servlet.
3. Write some code in the doGet() method.
4. Find the servers view in the Java EE perspective, it's usually one of the tabs at the bottom.
5. Right click in there and select new Server.
6. Select Tomcat X.X and a wizard will point you to finding the installation.
7. Right click the server you just created and select Add and Remove... and add your created web project.
8. Right click your servlet and select Run > Run on Server...

That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.

paste your .html file in assets folder of your project folder. and create an xml file in layout folder with the fol code: my.xml:

<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/webview"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
    />

add fol code in activity

setContentView(R.layout.my);
    WebView mWebView = null;
    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.loadUrl("file:///android_asset/new.html"); //new.html is html file name.

In case you are using axios and trying via a service call.

URL: https://react-16-demo.firebaseio.com/
Schema Name: todos
Key: -Lhu8a0uoSRixdmECYPE

axios.delete(`https://react-16-demo.firebaseio.com/todos/-Lhu8a0uoSRixdmECYPE.json`). then();

can help.

As you say, you don't need to request the file twice. Pass it from your controller to your directive. Assuming you use the directive inside the scope of the controller:

.controller('MyController', ['$scope', '$http', function($scope, $http) {
  $http.get('locations/locations.json').success(function(data) {
      $scope.locations = data;
  });
}

Then in your HTML (where you call upon the directive).
Note: locations is a reference to your controllers $scope.locations.

<div my-directive location-data="locations"></div>

And finally in your directive

...
scope: {
  locationData: '=locationData'
},
controller: ['$scope', function($scope){
  // And here you can access your data
  $scope.locationData
}]
...

This is just an outline to point you in the right direction, so it's incomplete and not tested.

Only load jQuery itself in the head, via CDN of course.

Why? In some scenarios you might include a partial template (e.g. ajax login form snippet) with embedded jQuery dependent code; if jQuery is loaded at page bottom, you get a "$ is not defined" error, nice.

There are ways to workaround this of course (such as not embedding any JS and appending to a load-at-bottom js bundle), but why lose the freedom of lazily loaded js, of being able to place jQuery dependent code anywhere you please? Javascript engine doesn't care where the code lives in the DOM so long as dependencies (like jQuery being loaded) are satisfied.

For your common/shared js files, yes, place them before </body>, but for the exceptions, where it really just makes sense application maintenance-wise to stick a jQuery dependent snippet or file reference right there at that point in the html, do so.

There is no performance hit loading jquery in the head; what browser on the planet does not already have jQuery CDN file in cache?

Much ado about nothing, stick jQuery in the head and let your js freedom reign.

I know is old topic but what about simple solution like while loop?

int function count(array[]) {

    int i = 0;

    while(array[i] != NULL) {

        i++;

    }

    return i;

}

I know that is slower than sizeof() but this is another example of array count.

You can check the total number of arguments which are passed in command line with "$#" Say for Example my shell script name is hello.sh

sh hello.sh hello-world
# I am passing hello-world as argument in command line which will b considered as 1 argument 
if [ $# -eq 1 ] 
then
    echo $1
else
    echo "invalid argument please pass only one argument "
fi

Output will be hello-world

In Laravel 5.6 I use

use Auth;
$user_id = Auth::user()->id;

as the other suggestion

Auth::id()

seems to apply to older versions of Laravel 5.x and didn't work for me.

On Mac OS X, I was experiencing the same problem. I wasn't able to launch a Xamarin app from Visual Studio, but a native Java Android project in Android Studio did work in the Virtual Device.

What I did was:

1. Unset the ANDROID_HOME and ANDROID_SDK_ROOT environment variables.

unset ANDROID_HOME
unset ANDROID_SDK_ROOT

2. Remove the existing virtual device that crashes. I did this in Visual Studio.
3. Create a new virtual device.

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

This process is simple, and follows the same flow as any git commit.

1. Make sure your repo is fully up to date. (ex: git pull)
2. Navigate to your repo folder on your local disk.
3. Delete the files you don't want anymore.
4. Then git commit -m "nuke and start again"
5. Then git push
6. Profit.

Over a certain message of size, it messes up the content when setting through $mail->Body.

You can test it, if it works well with small messages, but doesn't work with larger (over 4-6 kB), then this is the problem.

It seems to be the problem of $mail->Body, so you can get around this by setting the HTML body manually via $mail->MsgHTML($message). And then you can try to only add the non-html body by $mail->AltBody.

Hope that I could help, feel free to provide more details, information.

You can easily create a static object that represents a NULL return.

class Attr;
extern Attr AttrNull;

class Node {

} 

bool IsNull(const Attr& test) const {
    return &test == &AttrNull;
}

 private: 
   vector<Attr> attributes; 
};

And somewhere in a source file:

Your problem is that all chapters, whether they're in the appendix or not, default to starting on an odd-numbered page when you're in two-sided layout mode. A few possible solutions:

The simplest solution is to use the openany option to your document class, which makes chapters start on the next page, irrespective of whether it's an odd or even numbered page. This is supported in the standard book documentclass, eg \documentclass[openany]{book}. (memoir also supports using this as a declaration \openany which can be used in the middle of a document to change the behavior for subsequent pages.)

Another option is to try the \let\cleardoublepage\clearpage command before your appendices to avoid the behavior.

Or, if you don't care using a two-sided layout, using the option oneside to your documentclass (eg \documentclass[oneside]{book}) will switch to using a one-sided layout.

I would recommend to use XDoc and XElement of System.Xml.Linq instead of XmlDocument stuff. This would be better and you will be able to make use of the LINQ power in querying and parsing your XML:

Using XElement, your ToXml() method will look like the following:

public XElement ToXml()
{
    XElement element = new XElement("Song",
                        new XElement("Artist", "bla"),
                        new XElement("Title", "Foo"));

    return element;
}

If you are wanting to just copy the whole column, you can simplify the code a lot by doing something like this:

Sub CopyCol()

    Sheets("Sheet1").Columns(1).Copy

    Sheets("Sheet2").Columns(2).PasteSpecial xlPasteValues

End Sub

Or

Sub CopyCol()

    Sheets("Sheet1").Columns("A").Copy

    Sheets("Sheet2").Columns("B").PasteSpecial xlPasteValues

End Sub

Or if you want to keep the loop

Public Sub CopyrangeA()

    Dim firstrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    firstrowDB = 1
    arr1 = Array("BJ", "BK")
    arr2 = Array("A", "B")

    For i = LBound(arr1) To UBound(arr1)

        Sheets("Sheet1").Columns(arr1(i)).Copy

        Sheets("Sheet2").Columns(arr2(i)).PasteSpecial xlPasteValues

    Next
    Application.CutCopyMode = False

End Sub

Text='<%# DateTime.Parse(Eval("LastLoginDate").ToString()).ToString("MM/dd/yyyy hh:mm tt") %>'

This works for the format as you want

First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.

Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.

Here's how you should do it with all the suggestions above:

I would recommend using Properties.Settings to store values like ConnectionStrings and so on inside of the class library. This is where all the connection strings are stores in by suggestion from visual studio when you try to add a table adapter for example. enter image description here

And then they will be accessible by using this code every where in the clas library

var cs=  Properties.Settings.Default.[<name of defined setting>];

I found an up-to-date & unparalleled solution: https://www.npmjs.com/package/ts-mixer

You are welcome :)

1) in a query window in SQL Server Management Studio, run the command:

SET SHOWPLAN_ALL ON

2) run your slow query

3) your query will not run, but the execution plan will be returned. store this output

4) run your fast version of the query

5) your query will not run, but the execution plan will be returned. store this output

6) compare the slow query version output to the fast query version output.

7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

In my project I had the same error, I restarted Tomcat and it worked, withtout killing the java process.

After 5.0.13, in stored procedures, you can use dynamic SQL:

delimiter // 
CREATE PROCEDURE dynamic(IN tbl CHAR(64), IN col CHAR(64))
BEGIN
    SET @s = CONCAT('SELECT ',col,' FROM ',tbl );
    PREPARE stmt FROM @s;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
END
//
delimiter ;

Dynamic SQL does not work in functions or triggers. See the MySQL documentation for more uses.

The current draft of CSS Selectors Level 4 specifies structural selectors for grids. If implemented, we will be able to do things like:

th.price,
th.price || td {
    text-align: right;
}

Of course, that doesn't help us today -- the other answers here offer enough practical advice for that.

You can using option --data with file.

Write xml content to a file named is soap_get.xml and using curl command to send request:

curl -X POST --header "Content-Type:text/xml;charset=UTF-8" --data @soap_get.xml your_url

awk '{print $NF-1, $NF}'  inputfile

Note: this works only if at least two columns exist. On records with one column you will get a spurious "-1 column1"

Thanks for your answers, @mvp, @xero, I get what I want base on both of your answers.

git log --name-only 

or

git log --name-only --oneline

for short.

As an alternative to mentioned above. Call after data load:

Swift

collectionView.reloadData()
collectionView.layoutIfNeeded()
collectionView.selectItem(at: indexPath, animated: true, scrollPosition: .right)

This happens to me occasionally, usually it's just a simple oversight. Just pay attention to details, simple typos, etc. For example when copy/pasting import statements, like this:

My understanding of why python does not have ++ operator is following: When you write this in python a=b=c=1 you will get three variables (labels) pointing at same object (which value is 1). You can verify this by using id function which will return an object memory address:

In [19]: id(a)
Out[19]: 34019256

In [20]: id(b)
Out[20]: 34019256

In [21]: id(c)
Out[21]: 34019256

All three variables (labels) point to the same object. Now increment one of variable and see how it affects memory addresses:

In [22] a = a + 1

In [23]: id(a)
Out[23]: 34019232

In [24]: id(b)
Out[24]: 34019256

In [25]: id(c)
Out[25]: 34019256

You can see that variable a now points to another object as variables b and c. Because you've used a = a + 1 it is explicitly clear. In other words you assign completely another object to label a. Imagine that you can write a++ it would suggest that you did not assign to variable a new object but ratter increment the old one. All this stuff is IMHO for minimization of confusion. For better understanding see how python variables works:

In Python, why can a function modify some arguments as perceived by the caller, but not others?

Is Python call-by-value or call-by-reference? Neither.

Code Like a Pythonista: Idiomatic Python

req is an object containing information about the HTTP request that raised the event. In response to req, you use res to send back the desired HTTP response.

Those parameters can be named anything. You could change that code to this if it's more clear:

app.get('/user/:id', function(request, response){
  response.send('user ' + request.params.id);
});

Edit:

Say you have this method:

app.get('/people.json', function(request, response) { });

The request will be an object with properties like these (just to name a few):

• request.url, which will be "/people.json" when this particular action is triggered
• request.method, which will be "GET" in this case, hence the app.get() call.
• An array of HTTP headers in request.headers, containing items like request.headers.accept, which you can use to determine what kind of browser made the request, what sort of responses it can handle, whether or not it's able to understand HTTP compression, etc.
• An array of query string parameters if there were any, in request.query (e.g. /people.json?foo=bar would result in request.query.foo containing the string "bar").

To respond to that request, you use the response object to build your response. To expand on the people.json example:

app.get('/people.json', function(request, response) {
  // We want to set the content-type header so that the browser understands
  //  the content of the response.
  response.contentType('application/json');

  // Normally, the data is fetched from a database, but we can cheat:
  var people = [
    { name: 'Dave', location: 'Atlanta' },
    { name: 'Santa Claus', location: 'North Pole' },
    { name: 'Man in the Moon', location: 'The Moon' }
  ];

  // Since the request is for a JSON representation of the people, we
  //  should JSON serialize them. The built-in JSON.stringify() function
  //  does that.
  var peopleJSON = JSON.stringify(people);

  // Now, we can use the response object's send method to push that string
  //  of people JSON back to the browser in response to this request:
  response.send(peopleJSON);
});

If your problem is retaining the Console Window within Visual Studio without modifying your application (c-code) and are running it with Ctrl+F5 (when running Ctrl+F5) but the window is still closing the principal hint is to set the /SUBSYSTEM:CONSOLE linker option in your Visual Studio project.

as explained by DJMooreTX in http://social.msdn.microsoft.com/Forums/en-US/vcprerelease/thread/21073093-516c-49d2-81c7-d960f6dc2ac6

1) Open up your project, and go to the Solution Explorer. If you're following along with me in K&R, your "Solution" will be 'hello' with 1 project under it, also 'hello' in bold.

2. Right click on the 'hello" (or whatever your project name is.)

3. Choose "Properties" from the context menu.

4. Choose Configuration Properties>Linker>System.

5. For the "Subsystem" property in the right-hand pane, click the drop-down box in the right hand column.

6. Choose "Console (/SUBSYSTEM:CONSOLE)"

7. Click Apply, wait for it to finish doing whatever it does, then click OK. (If "Apply" is grayed out, choose some other subsystem option, click Apply, then go back and apply the console option. My experience is that OK by itself won't work.)

Now do Boris' CTRL-F5, wait for your program to compile and link, find the console window under all the other junk on your desktop, and read your program's output, followed by the beloved "Press any key to continue...." prompt.

Again, CTRL-F5 and the subsystem hints work together; they are not separate options.

I usually do what several of the other posters have said with regard to checking for it existing first and then doing whatever the correct path is. One thing you should remember when doing this is that the execution plan cached by sql could be nonoptimal for one path or the other. I believe the best way to do this is to call two different stored procedures.

FirstSP:
If Exists
   Call SecondSP (UpdateProc)
Else
   Call ThirdSP (InsertProc)

Now, I don't follow my own advice very often, so take it with a grain of salt.

Setting the src of a newly created iframe in javascript does not trigger the HTML parser until the element is inserted into the document. The HTML is then updated and the HTML parser will be invoked and process the attribute as expected.

http://jsfiddle.net/9k9Pe/2/

var iframe = document.createElement('iframe');
var html = '<body>Foo</body>';
iframe.src = 'data:text/html;charset=utf-8,' + encodeURI(html);
document.body.appendChild(iframe);
console.log('iframe.contentWindow =', iframe.contentWindow);

Also this answer your question it's important to note that this approach has compatibility issues with some browsers, please see the answer of @mschr for a cross-browser solution.

Check out this link: http://www.switchonthecode.com/tutorials/csharp-tutorial-image-editing-saving-cropping-and-resizing

private static Image cropImage(Image img, Rectangle cropArea)
{
   Bitmap bmpImage = new Bitmap(img);
   return bmpImage.Clone(cropArea, bmpImage.PixelFormat);
}

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

1. origin - This is a custom and most common name to point to remote.

$ git remote add origin https://github.com/git/git.git --- You will run this command to link your github project to origin. Here origin is user-defined. You can rename it by $ git remote rename old-name new-name

2. master - The default branch name in Git is master. For both remote and local computer.

3. origin/master - This is just a pointer to refer master branch in remote repo. Remember i said origin points to remote.

$ git fetch origin - Downloads objects and refs from remote repository to your local computer [origin/master]. That means it will not affect your local master branch unless you merge them using $ git merge origin/master. Remember to checkout the correct branch where you need to merge before run this command

Note: Fetched content is represented as a remote branch. Fetch gives you a chance to review changes before integrating them into your copy of the project. To show changes between yours and remote $git diff master..origin/master

int (t.strftime("%s")) also works

Minimalistic copy&paste-struct + lazy usage

If the idea is to have a minimalistic struct that you can use for quick tests, then I suggest you just copy and paste anywhere in your C++ file right after the #include's. This is the only instance in which I sacrifice Allman-style formatting.

You can easily adjust the precision in the first line of the struct. Possible values are: nanoseconds, microseconds, milliseconds, seconds, minutes, or hours.

#include <chrono>
struct MeasureTime
{
    using precision = std::chrono::microseconds;
    std::vector<std::chrono::steady_clock::time_point> times;
    std::chrono::steady_clock::time_point oneLast;
    void p() {
        std::cout << "Mark " 
                << times.size()/2
                << ": " 
                << std::chrono::duration_cast<precision>(times.back() - oneLast).count() 
                << std::endl;
    }
    void m() {
        oneLast = times.back();
        times.push_back(std::chrono::steady_clock::now());
    }
    void t() {
        m();
        p();
        m();
    }
    MeasureTime() {
        times.push_back(std::chrono::steady_clock::now());
    }
};

Usage

MeasureTime m; // first time is already in memory
doFnc1();
m.t(); // Mark 1: next time, and print difference with previous mark
doFnc2();
m.t(); // Mark 2: next time, and print difference with previous mark
doStuff = doMoreStuff();
andDoItAgain = doStuff.aoeuaoeu();
m.t(); // prints 'Mark 3: 123123' etc...

Standard output result

Mark 1: 123
Mark 2: 32
Mark 3: 433234

If you want summary after execution

If you want the report afterwards, because for example your code in between also writes to standard output. Then add the following function to the struct (just before MeasureTime()):

void s() { // summary
    int i = 0;
    std::chrono::steady_clock::time_point tprev;
    for(auto tcur : times)
    {
        if(i > 0)
        {
            std::cout << "Mark " << i << ": "
                    << std::chrono::duration_cast<precision>(tprev - tcur).count()
                    << std::endl;
        }
        tprev = tcur;
        ++i;
    }
}

So then you can just use:

MeasureTime m;
doFnc1();
m.m();
doFnc2();
m.m();
doStuff = doMoreStuff();
andDoItAgain = doStuff.aoeuaoeu();
m.m();
m.s();

Which will list all the marks just like before, but then after the other code is executed. Note that you shouldn't use both m.s() and m.t().

I think the correct answer should be java.sql.Timestamp is NOT timezone specific. Timestamp is a composite of java.util.Date and a separate nanoseconds value. There is no timezone information in this class. Thus just as Date this class simply holds the number of milliseconds since January 1, 1970, 00:00:00 GMT + nanos.

In PreparedStatement.setTimestamp(int parameterIndex, Timestamp x, Calendar cal) Calendar is used by the driver to change the default timezone. But Timestamp still holds milliseconds in GMT.

API is unclear about how exactly JDBC driver is supposed to use Calendar. Providers seem to feel free about how to interpret it, e.g. last time I worked with MySQL 5.5 Calendar the driver simply ignored Calendar in both PreparedStatement.setTimestamp and ResultSet.getTimestamp.

Your method must read byte by byte and fully understand and appreciate the byte wise construction of characters. The simplest method is to use an editor which will read anything but only output UTF-8 characters. Textpad is one choice.

If you are using Carbon you can do the following. You could also format this date to set an Expire HTTP Header.

Carbon::parse('tomorrow midnight')->format(Carbon::RFC7231_FORMAT)

Use the bootstrap built in classes input-large, input-medium, ... : <input type="text" class="input-large search-query">

Or use your own css:

1. Give the element a unique classname class="search-query input-mysize"
2. Add this in your css file (not the bootstrap.less or css files):
   .input-mysize { width: 150px }

Why don't you simply use set_index method?

In : col = ['a','b','c']

In : data = DataFrame([[1,2,3],[10,11,12],[20,21,22]],columns=col)

In : data
Out:
    a   b   c
0   1   2   3
1  10  11  12
2  20  21  22

In : data2 = data.set_index('a')

In : data2
Out:
     b   c
a
1    2   3
10  11  12
20  21  22

below works for mysql

update table1 INNER JOIN table2 on table1.col1 =  table2.col1
set table1.col1 =  table2.col2

If you really want to allocate and free a block of memory you can do this with direct ByteBuffers. There is even a non-portable way to free the memory.

However, as has been suggested, just because you have to free memory in C, doesn't mean it a good idea to have to do this.

If you feel you really have a good use case for free(), please include it in the question so we can see what you are rtying to do, it is quite likely there is a better way.

You need to check for the parameter being blank: if "%~1"=="" goto blank

Once you've done that, then do an if/else switch on -b: if "%~1"=="-b" (goto specific) else goto unknown

Surrounding the parameters with quotes makes checking for things like blank/empty/missing parameters easier. "~" ensures double quotes are stripped if they were on the command line argument.

I prefer:

class MTest extends Activity implements OnClickListener {
    public void onCreate(Bundle savedInstanceState) {
    ...
    Button b1 = (Button) findViewById(R.id.b1);
    Button b2 = (Button) findViewById(R.id.b2);
    b1.setOnClickListener(this);
    b2.setOnClickListener(this);
    ...
}

And then:

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.b1:
            ....
            break;
        case R.id.b2:
            ....
            break;
    }   
}

Switch-case is easier to maintain than if-else, and this implementation doesn't require making many class variables.

Following on from Richard's comment. Here's the easy way to convert your file to UNIX line endings. If you're like me you created it in Windows Notepad and then tried to run it in Linux - bad idea.

1. Download and install yourself a copy of Notepad++ (free).
2. Open your script file in Notepad++.
3. File menu -> Save As ->
4. Save as type: Unix script file (*.sh;*.bsh)
5. Copy the new .sh file to your Linux system
6. Maxe it executable with: chmod 755 the_script_filename
7. Run it with: ./the_script_filename

Any other problems try this link.

Here I am writing full query which will clear your all doubts

SELECT BillingDate,
       COUNT(*) AS BillingQty,
       SUM(BillingTotal) AS BillingSum
FROM Billings
WHERE BillingDate BETWEEN '2002-05-01' AND '2002-05-31'
GROUP BY BillingDate
HAVING COUNT(*) > 1
AND SUM(BillingTotal) > 100
ORDER BY BillingDate DESC

Shallow copy: Copies the member values from one object into another.

Deep Copy:    Copies the member values from one object into another.
                     Any pointer objects are duplicated and Deep Copied.

Example:

class String
{
     int   size;
     char* data;
};

String  s1("Ace");   // s1.size = 3 s1.data=0x0000F000

String  s2 = shallowCopy(s1);
 // s2.size =3 s2.data = 0X0000F000
String  s3 = deepCopy(s1);
 // s3.size =3 s3.data = 0x0000F00F
 //                      (With Ace copied to this location.)

The best practice is to ajax load the order information when click tr tag, and render the information html in $('#orderDetails') like this:

  $.get('the_get_order_info_url', { order_id: the_id_var }, function(data){
    $('#orderDetails').html(data);
  }, 'script')

Alternatively, you can add class for each td that contains the order info, and use jQuery method $('.class').html(html_string) to insert specific order info into your #orderDetails BEFORE you show the modal, like:

  <% @restaurant.orders.each do |order| %>
  <!-- you should add more class and id attr to help control the DOM -->
  <tr id="order_<%= order.id %>" onclick="orderModal(<%= order.id  %>);">
    <td class="order_id"><%= order.id %></td>
    <td class="customer_id"><%= order.customer_id %></td>
    <td class="status"><%= order.status %></td>
  </tr>
  <% end %>

js:

function orderModal(order_id){
  var tr = $('#order_' + order_id);
  // get the current info in html table 
  var customer_id = tr.find('.customer_id');
  var status = tr.find('.status');

  // U should work on lines here:
  var info_to_insert = "order: " + order_id + ", customer: " + customer_id + " and status : " + status + ".";
  $('#orderDetails').html(info_to_insert);

  $('#orderModal').modal({
    keyboard: true,
    backdrop: "static"
  });
};

That's it. But I strongly recommend you to learn sth about ajax on Rails. It's pretty cool and efficient.

I also faced the same situation. By setting following annotation above the property made it solve the exception prompted.

The Exception I faced.

Exception in thread "main" java.lang.IllegalStateException: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.model.Car_OneToMany

To overcome, the annotation I used.

    @OneToMany(cascade = {CascadeType.ALL})
    @Column(name = "ListOfCarsDrivenByDriver")
    private List<Car_OneToMany> listOfCarsBeingDriven = new ArrayList<Car_OneToMany>();

What made Hibernate throw the exception:

This exception is thrown at your console because the child object I attach to the parent object is not present in the database at that moment.

By providing @OneToMany(cascade = {CascadeType.ALL}) , it tells Hibernate to save them to the database while saving the parent object.

For Mac Users

I am using Mac and I was facing the same problem while I was trying to push a project from Android Studio. The reason for that is another user had previously logged into GitHub and his credentials were saved in Keychain Access.

The solution is to delete all the information store in keychain for that process

Leaving an answer for anyone looking to do something similar but in a horizontal direction, like I wanted to.

Tweaking @strider820's answer like below will do the magic:

.fixed-content {        //comments showing what I replaced.
    left:0;             //top: 0;
    right:0;            //bottom:0;
    position:fixed;
    overflow-y:hidden;  //overflow-y:scroll;
    overflow-x:auto;    //overflow-x:hidden;
}

That's it. Also check this comment where @train explained using overflow:auto over overflow:scroll.

Use the event listener's own function remove(). For example:

getEventListeners().click.forEach((e)=>{e.remove()})

This is an easy way to do it:

String formato = String.format("%.2f");

It sets the precision to 2 digits.

If you only want to print, use it this way:

System.out.printf("%.2f",123.234);

In addition to the above responses, it should be noted that there is, at least in theory, no restriction whatsoever as to what kind of resources are involved in a transaction.

Most of the time, it is just a database, or multiple distinct databases, but it is also conceivable that a printer takes part in a transaction, and can cause that transaction to fail, say in the event of a paper jam.

The magic you have been looking for has been added in Rails 6 Now you can upsert (update or insert). For single record use:

Model.upsert(column_name: value)

For multiple records use upsert_all :

Model.upsert_all(column_name: value, unique_by: :column_name)

Note:

• Both methods do not trigger Active Record callbacks or validations
• unique_by => PostgreSQL and SQLite only

The built-in matrix function has the nice option to enter data byrow. Combine that with an unlist on your source list will give you a matrix. We also need to specify the number of rows so it can break up the unlisted data. That is:

> matrix(unlist(a), byrow=TRUE, nrow=length(a) )
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5
[10,]   10    1    2    3    4    5

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>

There is a function called shift(). It will remove the first element of your array.

There is some good documentation and examples.

So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.

 protected void onCreate(Bundle savedInstanceState) {     setContentView(R.layout.my_layout);     Bitmap bitmap = getIntent().getParcelableExtra("image");     ImageView imageView = (ImageView) findViewById(R.id.imageview);     imageView.setImageBitmap(bitmap);  } 

Also check to see if you are missing the www in the url which was on my case

i was testing on http://www.mywebsite.com and in the facebook app i had set http://mywebsite.com

This issue occurs when someone has commited the code to develop/master and latest code has not been rebased from develop/master and you're trying to overwrite new changes to develop/master branch

Solution:

• Take a backup if you're working on feature branch and switch to master/develop branch by doing git checkout develop/master
• Do git pull
• You will get changes and merge conflicts occur when you have made changes in the same file which has not been rebased from develop/master
• Resolve the conflicts if it occurs and do git push,this should work

This is extremely easy to do in Sass! Don't delve into JavaScript for this. The & selector in sass does exactly this.

http://thesassway.com/intermediate/referencing-parent-selectors-using-ampersand

Vanilla:

window.addEventListener('scroll', function(ev) {

   var someDiv = document.getElementById('someDiv');
   var distanceToTop = someDiv.getBoundingClientRect().top;

   console.log(distanceToTop);
});

Open your browser console and scroll your page to see the distance.

IF you are working with postgresql there is a possibility that more than one schema may have table with same name in that case apply the below query

SELECT column_name, data_type 
FROM information_schema.columns
WHERE table_name = 'your_table_name' AND table_schema = 'your_schema_name’;

It was used during the typewriter era to move down a page to the next vertical stop, typically spaced 6 lines apart (much the same way horizontal tabs move along a line by 8 characters).

In modern day settings, the vt is of very little, if any, significance.

Most answers here suggest using parse_qs to parse an URL string. This method always returns the values as a list (not directly as a string) because a parameter can appear multiple times, e.g.:

http://example.com/?foo=bar&foo=baz&bar=baz

Would return:

{'foo': ['bar', 'baz'], 'bar' : ['baz']}

This is a bit inconvenient because in most cases you're dealing with an URL that doesn't have the same parameter multiple times. This function returns the first value by default, and only returns a list if there's more than one element.

from urllib import parse

def parse_urlargs(url):
    query = parse.parse_qs(parse.urlparse(url).query)
    return {k:v[0] if v and len(v) == 1 else v for k,v in query.items()}

For example, http://example.com/?foo=bar&foo=baz&bar=baz would return:

{'foo': ['bar', 'baz'], 'bar': 'baz'}

I received the same error after installing android studio and trying to run hello world. I think you need to use the SDK Manager inside Android Studio to install some things first.

Open up Android Studio, and click on the SDK Manager in the toolbar.

Now install the SDK tools you need.

• Tools -> Android SDK Tools
• Tools -> Android SDK Platform-tools
• Tools -> Android SDK Build-tools (highest version)

For each Android release you are targeting, hit the appropriate Android X.X folder and select (at a minimum):

• SDK Platform
• A system image for the emulator, such as ARM EABI v7a System Image

The SDK Manager will run (this can take a while) and download and install the various SDKs.

Inside Android Studio, File->Project Structure will show you where your Android sdks are installed. As you can see mine is c:\users\Joe\AppData\Local\Android\sdk1.

If I navigate to C:\Users\Joe\AppData\Local\Android\sdk1\sources you can see the various Android SDKs installed there...

Thread.sleep(1000);

is the worse: being a static wait, it will make test script slower.

driver.manage().timeouts.implicitlyWait(10,TimeUnit.SECONDS);

this is a dynamic wait

• it is valid till webdriver existence or has a scope till driver lifetime
• we can implicit wait also.

Finally, what I suggest is

WebDriverWait wait = new WebDriverWait(driver,20);
wait.until(ExpectedConditions.<different canned or predefined conditions are there>);

with some predefined conditions:

isAlertPresent();
elementToBeSelected();
visibilityOfElementLocated();
visibilityOfAllElementLocatedBy();
frameToBeAvailableAndSwitchToIt();

• It is also dynamic wait
• in this the wait will only be in seconds
• we have to use explicit wait for a particular web element on which we want to use.

There should be three pages here:

1. Initial login page with a form that asks for your username, but not your password.
2. You didn't mention this one, but I'd check whether the client computer is recognized, and if not, then challenge the user with either a CAPTCHA or else a security question. Otherwise the phishing site can simply use the tendered username to query the real site for the security image, which defeats the purpose of having a security image. (A security question is probably better here since with a CAPTCHA the attacker could have humans sitting there answering the CAPTCHAs to get at the security images. Depends how paranoid you want to be.)
3. A page after that that displays the security image and asks for the password.

I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.

I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.

You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST submission on step 1 (and 2 if applicable).

I found a dirty trick but it works, you could use the hover function to get the value before change!

Note that since git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1 and release note, June 2012) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

recurse-submodules=<check|on-demand>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

So you could push everything in one go with (from the parent repo) a:

git push --recurse-submodules=on-demand

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

With git 2.7 (January 2016), a simple git push will be enough to push the parent repo... and all its submodules.

See commit d34141c, commit f5c7cd9 (03 Dec 2015), commit f5c7cd9 (03 Dec 2015), and commit b33a15b (17 Nov 2015) by Mike Crowe (mikecrowe).
^{(Merged by Junio C Hamano -- gitster -- in commit 5d35d72, 21 Dec 2015)}

push: add recurseSubmodules config option

The --recurse-submodules command line parameter has existed for some time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's invent push.recurseSubmodules to provide a default for this parameter.
This also requires the addition of --recurse-submodules=no to allow the configuration to be overridden on the command line when required.

The most straightforward way to implement this appears to be to make push use code in submodule-config in a similar way to fetch.

The git config doc now include:

push.recurseSubmodules:

Make sure all submodule commits used by the revisions to be pushed are available on a remote-tracking branch.

• If the value is 'check', then Git will verify that all submodule commits that changed in the revisions to be pushed are available on at least one remote of the submodule. If any commits are missing, the push will be aborted and exit with non-zero status.
• If the value is 'on-demand' then all submodules that changed in the revisions to be pushed will be pushed. If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status. -
• If the value is 'no' then default behavior of ignoring submodules when pushing is retained.

You may override this configuration at time of push by specifying '--recurse-submodules=check|on-demand|no'.

So:

git config push.recurseSubmodules on-demand
git push

Git 2.12 (Q1 2017)

git push --dry-run --recurse-submodules=on-demand will actually work.

See commit 0301c82, commit 1aa7365 (17 Nov 2016) by Brandon Williams (mbrandonw).
^{(Merged by Junio C Hamano -- gitster -- in commit 12cf113, 16 Dec 2016)}

push run with --dry-run doesn't actually (Git 2.11 Dec. 2016 and lower/before) perform a dry-run when push is configured to push submodules on-demand.
Instead all submodules which need to be pushed are actually pushed to their remotes while any updates for the superproject are performed as a dry-run.
This is a bug and not the intended behaviour of a dry-run.

Teach push to respect the --dry-run option when configured to recursively push submodules 'on-demand'.
This is done by passing the --dry-run flag to the child process which performs a push for a submodules when performing a dry-run.

And still in Git 2.12, you now havea "--recurse-submodules=only" option to push submodules out without pushing the top-level superproject.

See commit 225e8bf, commit 6c656c3, commit 14c01bd (19 Dec 2016) by Brandon Williams (mbrandonw).

Restart Jenkins service

Just restart the Jenkins service after you changed the port in jenkins.xml.

1. Press Win + R
2. Type "services.msc"

3. Right click on the "Jenkins" line > Restart

   

4. Type http://localhost:8081/ in your browser to test the change.

Here is some code using java 6 to get you started:

JSONObject jo = new JSONObject();
jo.put("firstName", "John");
jo.put("lastName", "Doe");

JSONArray ja = new JSONArray();
ja.put(jo);

JSONObject mainObj = new JSONObject();
mainObj.put("employees", ja);

Edit: Since there has been a lot of confusion about put vs add here I will attempt to explain the difference. In java 6 org.json.JSONArray contains the put method and in java 7 javax.json contains the add method.

An example of this using the builder pattern in java 7 looks something like this:

JsonObject jo = Json.createObjectBuilder()
  .add("employees", Json.createArrayBuilder()
    .add(Json.createObjectBuilder()
      .add("firstName", "John")
      .add("lastName", "Doe")))
  .build();

If you don't like split() and you don't mind NAs padding out your short tail:

chunk <- function(x, n) { if((length(x)%%n)==0) {return(matrix(x, nrow=n))} else {return(matrix(append(x, rep(NA, n-(length(x)%%n))), nrow=n))} }

The columns of the returned matrix ([,1:ncol]) are the droids you are looking for.

You can find the number of characters using system function LEN. i.e.

SELECT LEN(Column) FROM TABLE

Plain and simple:

If Jenkins sees the build step (which is a script too) exits with non-zero code, the build is marked with a red ball (= failed).

Why exactly that happens depends on your build script.

I wrote something similar from another point-of-view but maybe it will help to read it anyway: Why does Jenkins think my build succeeded?

Why are you sending it through a post if you already have it on the server (PHP) side?

Why not just save the array to s $_SESSION variable so you can use it when the form gets submitted, that might make it more "secure" since then the client cannot change the variables by editing the source.

It all depends on what you really want to do.

funcdict = {
  'mypackage.mymodule.myfunction': mypackage.mymodule.myfunction,
    ....
}

funcdict[myvar](parameter1, parameter2)

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

Unlike div, p ¹ which are Block Level elements which can take up margin on all sides,span² cannot as it's an Inline element which takes up margins horizontally only.

From the specification:

Margin properties specify the width of the margin area of a box. The 'margin' shorthand property sets the margin for all four sides while the other margin properties only set their respective side. These properties apply to all elements, but vertical margins will not have any effect on non-replaced inline elements.

Demo 1 (Vertical margin not applied as span is an inline element)

Solution? Make your span element, display: inline-block; or display: block;.

Demo 2

Would suggest you to use display: inline-block; as it will be inline as well as block. Making it block only will result in your element to render on another line, as block level elements take 100% of horizontal space on the page, unless they are made inline-block or they are floated to left or right.

^{1. Block Level Elements - MDN Source}

^{2. Inline Elements - MDN Resource}

While working on a .Net app build with EF code first, I got this error message when trying to apply my migration where I had a Sql("UPDATE tableName SET columnName = value"); statement.

Turns out I misspelled the columnName.

I was looking for same answer & found this info from wiki useful: Loop Instructions

The loop instruction decrements ECX and jumps to the address specified by arg unless decrementing ECX caused its value to become zero. For example:

 mov ecx, 5
 start_loop:
 ; the code here would be executed 5 times
 loop start_loop

loop does not set any flags.

loopx arg

These loop instructions decrement ECX and jump to the address specified by arg if their condition is satisfied (that is, a specific flag is set), unless decrementing ECX caused its value to become zero.

• loope loop if equal

• loopne loop if not equal

• loopnz loop if not zero

• loopz loop if zero

I prefer foxy's answer because we should never use javascript when existing css properties are made for the job.

Don't forget to add display: block ; in .menuItem, so height and width are taken into account.

edit : for better script/look&feel decoupling, if you ever need to change style through jQuery I'd define an additional css class and use $(...).addClass("myclass") and $(...).removeClass("myclass")

// How about this
function queryString(qs) {
    var queryStr = qs.substr(1).split("&"),obj={};
    for(var i=0; i < queryStr.length;i++)
        obj[queryStr[i].split("=")[0]] = queryStr[i].split("=")[1];
    return obj;
}

// Usage:
var result = queryString(location.search);

Use .loc for label based indexing:

df.loc[df.A==0, 'B'] = np.nan

The df.A==0 expression creates a boolean series that indexes the rows, 'B' selects the column. You can also use this to transform a subset of a column, e.g.:

df.loc[df.A==0, 'B'] = df.loc[df.A==0, 'B'] / 2

I don't know enough about pandas internals to know exactly why that works, but the basic issue is that sometimes indexing into a DataFrame returns a copy of the result, and sometimes it returns a view on the original object. According to documentation here, this behavior depends on the underlying numpy behavior. I've found that accessing everything in one operation (rather than [one][two]) is more likely to work for setting.

This is my code for a function that gets the tasks and gets their names, also adding them into a list to be accessed from a list. It creates temp files with the data, reads the files and gets the task name with the .exe suffix, and arranges the files to be deleted when the program has exited with System.exit(0), it also hides the processes being used to get the tasks and also java.exe so that the user can't accidentally kill the process that runs the program all together.

on macOS (/ OS X), if someone else is having trouble with the OS apparently leaking memory:

• https://github.com/phvu/cuda-smi is useful for quickly checking free memory
• Quitting applications seems to free the memory they use. Quit everything you don't need, or quit applications one-by-one to see how much memory they used.
• If that doesn't cut it (quitting about 10 applications freed about 500MB / 15% for me), the biggest consumer by far is WindowServer. You can Force quit it, which will also kill all applications you have running and log you out. But it's a bit faster than a restart and got me back to 90% free memory on the cuda device.

This pattern should work:

#\d

foreach(var match in System.Text.RegularExpressions.RegEx.Matches(input, "#\d"))
{
    Console.WriteLine(match.Value);
}

(I'm not in front of Visual Studio, but even if that doesn't compile as-is, it should be close enough to tweak into something that works).

In my case, I was trying to fire a custom event from the parent document, and receive it in the child iframe, so I had to do the following:

var event = new CustomEvent('marker-metrics', {
    detail: // extra payload data here
});
var iframe = document.getElementsByTagName('iframe');
iframe[0].contentDocument.dispatchEvent(event)

and in the iframe document:

document.addEventListener('marker-metrics', (e) => {
  console.log('@@@@@', e.detail);
});

I think, you could also do something like...

setTimeout(function(){
    $(".message-class").trigger("click");
}, 5000);

and do your animated effects on the event-click...

$(".message-class").click(function() {
    //your event-code
});

If the problem is that you are not seeing your changes to the file take effect, just open a new terminal window, and it will be "sourced". You will be able to use the proper PATH etc with each subsequent terminal window.

I had the same problem and the best solution I found is to first create the table defining primary key and then to use insert into statement.

CREATE TABLE mytable (
field1 INTEGER PRIMARY KEY,
field2 TEXT
);

INSERT INTO mytable 
SELECT field1, field2 
FROM anothertable;

You can use the following:

$hashed_password = Hash::make('Your Unhashed Password');

You can find more information: here

To add a WHERE clause inside an INSERT statement simply;

INSERT INTO table_name (column1,column2,column3)

Contrary to many answers and comments on SO and other sites, you do NOT have to perform preliminary tests with an alpha/beta version of your product that has been downloaded from Google Play onto your test device (the alpha/beta publication process often eats up half a day). Neither do you have to load and re-load a signed release apk from your developer studio to your test device.

You CAN debug preliminary Google Play in app billing services using the debug app as loaded from your developer studio directly to your test device via ADB. If you are experiencing errors that prevent this, likely you have done something wrong in your code. Pay especially close attention to the CASE of your SKU's (product ids) and their format (for example, if you load your APK as com.mydomain.my_product_id, be sure your try to purchase it this way - providing the same case and domain). Also, pay especially close attention to your itemType - this should be either "inapp" or "subs" for managed/unmanaged in app purchases or subscriptions, respectively.

As suggested by Chirag Patel, provided you have your billing code properly established, perform all testing using the android.test.purchased Sku (product ID) during your preliminary tests. Check for this ID throughout your billing operations to pass it through signature, token and payload checks, since this data is not provided by the Google test system. Additionally, give one of your test products this ID to test its purchase, unlock/load and presentation all the way through your schema. To CLEAR the purchase, simply consume it, passing the same Sku AND a token string formatted this way - no other fields are relevant :

    "inapp:"+appContext.getAppContext().getPackageName()+":android.test.purchased";

Once you have completed this phase of testing, move to semi-live testing with your alpha/beta product. Create a Google group (essentially a mailing list), add your test users emails to it, and add/invite this group to test your device in this phase (performed at the "APK" portion of your app's Google developer listing). Purchases will be simulated but not actually charged - however to clear and re-test the purchases, Google indicates that you must refund them from your Google wallet. THIS is the only phase of testing that requires the time-consuming process of using alpha/beta loads and test users.

You can use the % operator to find the remainder of a division, and compare the result with 0.

Example:

if (number % divisor == 0)
{
    //code for perfect divisor
}
else
{
    //the number doesn't divide perfectly by divisor
}

I had this error when i was using the azure storage as a static website, the js files that are copied had the content type as text/plain; charset=utf-8 and i changed the content type to application/javascript

It started working.

Example: A house is worth $100,000, and it is appreciating at $1000 per year.

To keep track of the current house value, you would use a database as the value would change every year.

Three years later, you would be able to see the value of the house which is $103,000.

To keep track of the historical house value, you would use a data warehouse as the value of the house should be

$100,000 on year 0, 
$101,000 on year 1, 
$102,000 on year 2, 
$103,000 on year 3. 

What I came here looking for is how to actually get the stash back, regardless of what I have checked out. In particular, I had stashed something, then checked out an older version, then poped it, but the stash was a no-op at that earlier time point, so the stash disappeared; I couldn't just do git stash to push it back on the stack. This worked for me:

$ git checkout somethingOld
$ git stash pop
...
nothing added to commit but untracked files present (use "git add" to track)
Dropped refs/stash@{0} (27f6bd8ba3c4a34f134e12fe69bf69c192f71179)
$ git checkout 27f6bd8ba3c
$ git reset HEAD^    # Make the working tree differ from the parent.
$ git stash # Put the stash back in the stack.
Saved working directory and index state WIP on (no branch): c2be516 Some message.
HEAD is now at c2be516 Some message.
$ git checkout somethingOld # Now we are back where we were.

In retrospect, I should have been using git stash apply not git stash pop. I was doing a bisect and had a little patch that I wanted to apply at every bisect step. Now I'm doing this:

$ git reset --hard; git bisect good; git stash apply
$ # Run tests
$ git reset --hard; git bisect bad; git stash apply
etc.

Here is my solution and it's also working, when element shows into the viewport

var counterTeaserL = $('.go-counterTeaser');
var winHeight = $(window).height();
if (counterTeaserL.length) {
    var firEvent = false,
        objectPosTop = $('.go-counterTeaser').offset().top;

        //when element shows at bottom
        var elementViewInBottom = objectPosTop - winHeight;
    $(window).on('scroll', function() {
        var currentPosition = $(document).scrollTop();
        //when element position starting in viewport
      if (currentPosition > elementViewInBottom && firEvent === false) {
        firEvent = true;
        animationCounter();
      }   
    });
}

//counter function will animate by using external js also add seprator "."
 function animationCounter(){
        $('.numberBlock h2').each(function () {
            var comma_separator_number_step =           $.animateNumber.numberStepFactories.separator('.');
            var counterValv = $(this).text();
            $(this).animateNumber(
                {
                  number: counterValv,
                  numberStep: comma_separator_number_step
                }
            );
        });
    }

Check that if you have a static handler in your class. If so, please be careful, cause static handler only could be initiated in thread which has a looper, the crash could be triggered in this way:

1.firstly, create the instance of class in a simple thread and catch the crash.

2.then call the field method of Class in main thread, you will get the NoClassDefFoundError.

here is the test code:

public class MyClass{
       private static  Handler mHandler = new Handler();
       public static int num = 0;
}

in your onCrete method of Main activity, add test code part:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //test code start
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                MyClass myClass = new MyClass();
            } catch (Throwable e) {
                e.printStackTrace();
            }
        }
    }).start();

    try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    MyClass.num = 3;
    // end of test code
}

there is a simple way to fix it using a handlerThread to init handler:

private static Handler mHandler;
private static HandlerThread handlerThread = new HandlerThread("newthread");
static {
    handlerThread.start();
    mHandler = new Handler(handlerThread.getLooper(), mHandlerCB);
}

To justify the bootstrap 3 navbar-nav justify menu to 100% width you can use this code:

@media (min-width: 768px){
    .navbar-nav {
        margin: 0 auto;
        display: table;
        table-layout: auto;
        float: none;
        width: 100%;
    }
    .navbar-nav>li {
        display: table-cell;
        float: none;
        text-align: center;
    }
} 

I know this is old as dirt but it ranked pretty high in google.

The problem with the solution maddy implemented (in response to rahul) to maintain the use of a While...Wend loop has some drawbacks

In the example given

num = 0
While num < 10
  If status = "Fail" Then
    num = 10
  End If
  num = num + 1
Wend

After status = "Fail" num will actually equal 11. The loop didn't end on the fail condition, it ends on the next test. All of the code after the check still processed and your counter is not what you might have expected it to be.

Now depending on what you are all doing in your loop it may not matter, but then again if your code looked something more like:

num = 0
While num < 10
  If folder = "System32" Then
    num = 10
  End If
  RecursiveDeleteFunction folder
  num = num + 1
Wend

Using Do While or Do Until allows you to stop execution of the loop using Exit Do instead of using trickery with your loop condition to maintain the While ... Wend syntax. I would recommend using that instead.

Whenever you have to perform some action on the click of the Spinner in Android, use the following method.

mspUserState.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatIsRequired();
        }
        return false;
    }
});

One thing to keep in mind is always to return False while using the above method. If you will return True then the dropdown items of the spinner will not be displayed on clicking the Spinner.

you can use style

   <td  colspan="2">
     <div style="float:left; width:80px"><asp:Label ID="Label6" runat="server" Text="Label"></asp:Label></div>

    <div style="float: right; width:100px">    
            <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
    </div>

     <div style="clear:both"></div>

You Need to create a notification channel for API level above 26(oreo).

`NotificationChannel channel = new NotificationChannel(STRING_ID,CHANNEL_NAME,NotificationManager.IMPORTANCE_HIGH);

STRING_ID = string notification channelid is the same as in Notification.Builder like this

`Notification notification = new Notification.Builder(this,STRING_ID)
            .setSmallIcon(android.R.drawable.ic_menu_help)
            .setContentTitle("Hello Notification")
            .setContentText("It is Working")
            .setContentIntent(pendingIntent)
            .build();`

Channel id in the notification and in the notification should be same Whole code is like this.. `

@RequiresApi(api = Build.VERSION_CODES.O)
  private void callNotification2() {

    Intent intent = new Intent(getApplicationContext(),MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,11, 
    intent,PendingIntent.FLAG_UPDATE_CURRENT);
    Notification notification = new Notification.Builder(this,"22")
            .setSmallIcon(android.R.drawable.ic_menu_help)
            .setContentTitle("Hello Notification")
            .setContentText("It is Working")
            .setContentIntent(pendingIntent)
            .build();
    NotificationChannel channel = new 
    NotificationChannel("22","newName",NotificationManager.IMPORTANCE_HIGH);
    NotificationManager manager = (NotificationManager) 
    getSystemService(NOTIFICATION_SERVICE);
    manager.createNotificationChannel(channel);
    manager.notify(11,notification);

    }'

It means maven is not able to download artifacts from repository. Following steps will help you:

1. Go to repository browser and check if artifact exist.
2. Check settings.xml to see if proper respository is specified.
3. Check proxy settings.

If you use moment.js, they have an add function. Here's the link - https://momentjs.com/docs/#/manipulating/add/

moment().add(7, 'months');

I also wrote a recursive function based on paxdiablo's answer to add a variable number of months. By default this function would add a month to the current date.

function addMonths(after = 1, now = new Date()) {
        var current;
        if (now.getMonth() == 11) {
            current = new Date(now.getFullYear() + 1, 0, 1);
        } else {
            current = new Date(now.getFullYear(), now.getMonth() + 1, 1);            
        }
        return (after == 1) ? current : addMonths(after - 1, new Date(now.getFullYear(), now.getMonth() + 1, 1))
    }

Example

console.log('Add 3 months to November', addMonths(3, new Date(2017, 10, 27)))

Output -

Add 3 months to November Thu Feb 01 2018 00:00:00 GMT-0800 (Pacific Standard Time)

You are right that it should work; perhaps you forgot to instantiate something. Does your code look something like this?

String rssFeedURL = "http://stackoverflow.com";
this.rssFeedURLS = new ArrayList<String>();
this.rssFeedURLS.add(rssFeedURL);
if(this.rssFeedURLs.contains(rssFeedURL)) {
// this code will execute
}

For reference, note that the following conditional will also execute if you append this code to the above:

String copyURL = new String(rssFeedURL);
if(this.rssFeedURLs.contains(copyURL)) {
// code will still execute because contains() checks equals()
}

Even though (rssFeedURL == copyURL) is false, rssFeedURL.equals(copyURL) is true. The contains method cares about the equals method.

Try maybe this way

try{
    double d= Double.valueOf(someString);
    if (d==(int)d){
        System.out.println("integer"+(int)d);
    }else{
        System.out.println("double"+d);
    }
}catch(Exception e){
    System.out.println("not number");
}

But all numbers outside Integers range (like "-1231231231231231238") will be treated as doubles. If you want to get rid of that problem you can try it this way

try {
    double d = Double.valueOf(someString);
    if (someString.matches("\\-?\\d+")){//optional minus and at least one digit
        System.out.println("integer" + d);
    } else {
        System.out.println("double" + d);
    }
} catch (Exception e) {
    System.out.println("not number");
}

Download Microsoft Rdlc Report Designer for Visual Studio from this link. https://marketplace.visualstudio.com/items?itemName=ProBITools.MicrosoftRdlcReportDesignerforVisualStudio-18001

Microsoft explain the steps in details:

https://docs.microsoft.com/en-us/sql/reporting-services/application-integration/integrating-reporting-services-using-reportviewer-controls-get-started?view=sql-server-2017

The following steps summarizes the above article.

Adding the Report Viewer control to a new web project:

1. Create a new ASP.NET Empty Web Site or open an existing ASP.NET project.

2. Install the Report Viewer control NuGet package via the NuGet package manager console. From Visual Studio -> Tools -> NuGet Package Manager -> Package Manager Console

   Install-Package Microsoft.ReportingServices.ReportViewerControl.WebForms
   

3. Add a new .aspx page to the project and register the Report Viewer control assembly for use within the page.

   <%@ Register assembly="Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" namespace="Microsoft.Reporting.WebForms" tagprefix="rsweb" %>
   

4. Add a ScriptManagerControl to the page.

5. Add the Report Viewer control to the page. The snippet below can be updated to reference a report hosted on a remote report server.

    <rsweb:ReportViewer ID="ReportViewer1" runat="server" ProcessingMode="Remote">
    <ServerReport ReportPath="" ReportServerUrl="" /></rsweb:ReportViewer>
   

The final page should look like the following.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Sample" %>

<%@ Register assembly="Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" namespace="Microsoft.Reporting.WebForms" tagprefix="rsweb" %>

UPDATE 24.04.2016.

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)

EDIT

I've tested this on Twenty Fifteen and it's working, so it should be working for you.

In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:

    <div id="ajax-posts" class="row">
        <?php
            $postsPerPage = 3;
            $args = array(
                    'post_type' => 'post',
                    'posts_per_page' => $postsPerPage,
                    'cat' => 8
            );

            $loop = new WP_Query($args);

            while ($loop->have_posts()) : $loop->the_post();
        ?>

         <div class="small-12 large-4 columns">
                <h1><?php the_title(); ?></h1>
                <p><?php the_content(); ?></p>
         </div>

         <?php
                endwhile;
        wp_reset_postdata();
         ?>
    </div>
    <div id="more_posts">Load More</div>

This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with

$cat_id = get_query_var('cat');

This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like

<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>

And pull the category with

var cat = $('#more_posts').data('category');

But for now, you can leave this out.

Next in functions.php I added

wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
    'ajaxurl' => admin_url( 'admin-ajax.php' ),
    'noposts' => __('No older posts found', 'twentyfifteen'),
));

Right after the existing wp_localize_script. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.

At the end of the functions.php file I added the function that will load your posts:

function more_post_ajax(){

    $ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
    $page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;

    header("Content-Type: text/html");

    $args = array(
        'suppress_filters' => true,
        'post_type' => 'post',
        'posts_per_page' => $ppp,
        'cat' => 8,
        'paged'    => $page,
    );

    $loop = new WP_Query($args);

    $out = '';

    if ($loop -> have_posts()) :  while ($loop -> have_posts()) : $loop -> the_post();
        $out .= '<div class="small-12 large-4 columns">
                <h1>'.get_the_title().'</h1>
                <p>'.get_the_content().'</p>
         </div>';

    endwhile;
    endif;
    wp_reset_postdata();
    die($out);
}

add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');

Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.

If you've added your category in the loader, you'd add:

$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';

And instead of 8, you'd put $cat. This will be in the $_POST array, and you'll be able to use it in ajax.

Last part is the ajax itself. In functions.js I put inside the $(document).ready(); enviroment

var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;


function load_posts(){
    pageNumber++;
    var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
    $.ajax({
        type: "POST",
        dataType: "html",
        url: ajax_posts.ajaxurl,
        data: str,
        success: function(data){
            var $data = $(data);
            if($data.length){
                $("#ajax-posts").append($data);
                $("#more_posts").attr("disabled",false);
            } else{
                $("#more_posts").attr("disabled",true);
            }
        },
        error : function(jqXHR, textStatus, errorThrown) {
            $loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
        }

    });
    return false;
}

$("#more_posts").on("click",function(){ // When btn is pressed.
    $("#more_posts").attr("disabled",true); // Disable the button, temp.
    load_posts();
});

Saved it, tested it, and it works :)

Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD

UPDATE

For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;) you can try with

$(window).on('scroll', function () {
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

This should run the load_posts() function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer

$(window).on('scroll', function(){
    if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
        if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
                load_posts();
        }
    }
});

Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100 or $('footer').offset().top for some reason. If that should happen, just increase the number where the scroll goes to.

You can easily check it by putting console.logs in your code and see in the inspector what they throw out

$(window).on('scroll', function () {
    console.log($(window).scrollTop() + $(window).height());
    console.log($(document).height() - 100);
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

And just adjust accordingly ;)

Hope this helps :) If you have any questions just ask.

Try this:

Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(1220227200 * 1000);
System.out.println(cal.getTime());

The LockedOut property is what you are looking for among all the properties you returned. You are only seeing incomplete output in TechNet. The information is still there. You can isolate that one property using Select-Object

Get-ADUser matt -Properties * | Select-Object LockedOut

LockedOut
---------
False

The link you referenced doesn't contain this information which is obviously misleading. Test the command with your own account and you will see much more information.

Note: Try to avoid -Properties *. While it is great for simple testing it can make queries, especially ones with multiple accounts, unnecessarily slow. So, in this case, since you only need lockedout:

Get-ADUser matt -Properties LockedOut | Select-Object LockedOut

Below code from Python | How to Count the frequency of a word in the text file? worked for me.

 import re
    frequency = {}
    #Open the sample text file in read mode.
    document_text = open('sample.txt', 'r')
    #convert the string of the document in lowercase and assign it to text_string variable.
    text = document_text.read().lower()
    pattern = re.findall(r'\b[a-z]{2,15}\b', text)
    for word in pattern:
         count = frequency.get(word,0)
         frequency[word] = count + 1
     frequency_list = frequency.keys()
     for words in frequency_list:
         print(words, frequency[words])

bundle exec gem uninstall foo
bundle update foo

But I am not sure everyone needs to run these two steps.

window.location.href = 'URL';

is the standard implementation for changing the current window's location.

I assume your talking about windows forms:

To display your form use the Show() method:

Form form2 = new Form();
form2.Show();

to close the form use Close():

form2.Close();

It is possible to style an SVG by dynamically creating a style element in JavaScript and appending it to the SVG element. Hacky, but it works.

<object id="dynamic-svg" type="image/svg+xml" data="your-svg.svg">
    Your browser does not support SVG
</object>
<script>
    var svgHolder = document.querySelector('object#dynamic-svg');
    svgHolder.onload = function () {
        var svgDocument = svgHolder.contentDocument;
        var style = svgDocument.createElementNS("http://www.w3.org/2000/svg", "style");

        // Now (ab)use the @import directive to load make the browser load our css
        style.textContent = '@import url("/css/your-dynamic-css.css");';

        var svgElem = svgDocument.querySelector('svg');
        svgElem.insertBefore(style, svgElem.firstChild);
    };
</script>

You could generate the JavaScript dynamically in PHP if you want to - the fact that this is possible in JavaScript opens a myriad of possibilities.

All you need is data-target=".navbar-collapse" in the button, nothing else.

<button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".navbar-collapse">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
</button>

my runner script looks like :

{
    "version": "0.1.0",

    "command": "explorer",

    "windows": {
        "command": "explorer.exe"
    },

    "args": ["{$file}"]
}

and it's just open my explorer when I press ctrl shift b in my index.html file

For people like me, linq addicts, and based on svick's answer, here a linq approach:

using System.Linq;
//...
//make it linq iterable. 
var obj_linq = Response.Cast<KeyValuePair<string, JToken>>();

Now you can make linq expressions like:

JToken x = obj_linq
          .Where( d => d.Key == "my_key")
          .Select(v => v)
          .FirstOrDefault()
          .Value;
string y = ((JValue)x).Value;

Or just:

var y = obj_linq
       .Where(d => d.Key == "my_key")
       .Select(v => ((JValue)v.Value).Value)
       .FirstOrDefault();

Or this one to iterate over all data:

obj_linq.ToList().ForEach( x => { do stuff } );

You can use the forEach method to execute a provided function once for each element in the array. In this provided function you can add the Active property to the element.

Results.forEach(function (element) {
  element.Active = "false";
});

If you're using org.codehaus.jackson, this has been possible since 1.6. You can convert a JsonNode to a POJO with ObjectMapper#readValue: http://jackson.codehaus.org/1.9.4/javadoc/org/codehaus/jackson/map/ObjectMapper.html#readValue(org.codehaus.jackson.JsonNode, java.lang.Class)

    ObjectMapper mapper = new ObjectMapper();
    JsonParser jsonParser = mapper.getJsonFactory().createJsonParser("{\"foo\":\"bar\"}");
    JsonNode tree = jsonParser.readValueAsTree();
    // Do stuff to the tree
    mapper.readValue(tree, Foo.class);

If you are on Red Hat/CentOS:

# To allow for building python ssl libs
yum install openssl-devel
# Download the source of *any* python version
cd /usr/src
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
tar xf Python-3.6.2.tar.xz 
cd Python-3.6.2

# Configure the build w/ your installed libraries
./configure

# Install into /usr/local/bin/python3.6, don't overwrite global python bin
make altinstall

I fixed the issue by using these command lines

• $ rm -rf node_modules/
• $ sudo npm update -g npm
• $ npm install

It's done!

I believe that npm install should not run in a production environment. There are several things that can go wrong - npm outage, download of newer dependencies (shrinkwrap seems to have solved this) are two of them.

On the other hand, folder node_modules should not be committed to Git. Apart from their big size, commits including them can become distracting.

The best solutions would be this: npm install should run in a CI environment that is similar to the production environment. All tests will run and a zipped release file will be created that will include all dependencies.

You can use the localeCompare() method.

string_a.localeCompare(string_b);

/* Expected Returns:

 0:  exact match

-1:  string_a < string_b

 1:  string_a > string_b

 */

Here's an efficient option that doesn't use the clipboard.

Sub transposeAndPasteRow(rowToCopy As Range, pasteTarget As Range)
    pasteTarget.Resize(rowToCopy.Columns.Count) = Application.WorksheetFunction.Transpose(rowToCopy.Value)
End Sub

Use it like this.

Sub test()
    Call transposeAndPasteRow(Worksheets("Sheet1").Range("A1:A5"), Worksheets("Sheet2").Range("A1"))
End Sub

6. Restart All services. Done. Resolved

If we split it up, the mess is equal to:

++[[]][+[]]
+
[+[]]

In JavaScript, it is true that +[] === 0. + converts something into a number, and in this case it will come down to +"" or 0 (see specification details below).

Therefore, we can simplify it (++ has precendence over +):

++[[]][0]
+
[0]

Because [[]][0] means: get the first element from [[]], it is true that:

[[]][0] returns the inner array ([]). Due to references it's wrong to say [[]][0] === [], but let's call the inner array A to avoid the wrong notation.

++ before its operand means “increment by one and return the incremented result”. So ++[[]][0] is equivalent to Number(A) + 1 (or +A + 1).

Again, we can simplify the mess into something more legible. Let's substitute [] back for A:

(+[] + 1)
+
[0]

Before +[] can coerce the array into the number 0, it needs to be coerced into a string first, which is "", again. Finally, 1 is added, which results in 1.

• (+[] + 1) === (+"" + 1)
• (+"" + 1) === (0 + 1)
• (0 + 1) === 1

Let's simplify it even more:

1
+
[0]

Also, this is true in JavaScript: [0] == "0", because it's joining an array with one element. Joining will concatenate the elements separated by ,. With one element, you can deduce that this logic will result in the first element itself.

In this case, + sees two operands: a number and an array. It’s now trying to coerce the two into the same type. First, the array is coerced into the string "0", next, the number is coerced into a string ("1"). Number + String === String.

"1" + "0" === "10" // Yay!

Specification details for +[]:

This is quite a maze, but to do +[], first it is being converted to a string because that's what + says:

11.4.6 Unary + Operator

The unary + operator converts its operand to Number type.

The production UnaryExpression : + UnaryExpression is evaluated as follows:

1. Let expr be the result of evaluating UnaryExpression.

2. Return ToNumber(GetValue(expr)).

ToNumber() says:

Object

Apply the following steps:

1. Let primValue be ToPrimitive(input argument, hint String).

2. Return ToString(primValue).

ToPrimitive() says:

Object

Return a default value for the Object. The default value of an object is retrieved by calling the [[DefaultValue]] internal method of the object, passing the optional hint PreferredType. The behaviour of the [[DefaultValue]] internal method is defined by this specification for all native ECMAScript objects in 8.12.8.

[[DefaultValue]] says:

8.12.8 [[DefaultValue]] (hint)

When the [[DefaultValue]] internal method of O is called with hint String, the following steps are taken:

1. Let toString be the result of calling the [[Get]] internal method of object O with argument "toString".

2. If IsCallable(toString) is true then,

a. Let str be the result of calling the [[Call]] internal method of toString, with O as the this value and an empty argument list.

b. If str is a primitive value, return str.

The .toString of an array says:

15.4.4.2 Array.prototype.toString ( )

When the toString method is called, the following steps are taken:

1. Let array be the result of calling ToObject on the this value.

2. Let func be the result of calling the [[Get]] internal method of array with argument "join".

3. If IsCallable(func) is false, then let func be the standard built-in method Object.prototype.toString (15.2.4.2).

4. Return the result of calling the [[Call]] internal method of func providing array as the this value and an empty arguments list.

So +[] comes down to +"", because [].join() === "".

Again, the + is defined as:

11.4.6 Unary + Operator

The unary + operator converts its operand to Number type.

The production UnaryExpression : + UnaryExpression is evaluated as follows:

1. Let expr be the result of evaluating UnaryExpression.

2. Return ToNumber(GetValue(expr)).

ToNumber is defined for "" as:

The MV of StringNumericLiteral ::: [empty] is 0.

So +"" === 0, and thus +[] === 0.

If you use nested sets (sometimes referred to as Modified Pre-order Tree Traversal) you can extract the entire tree structure or any subtree within it in tree order with a single query, at the cost of inserts being more expensive, as you need to manage columns which describe an in-order path through thee tree structure.

For django-mptt, I used a structure like this:

id  parent_id  tree_id  level  lft  rght
--  ---------  -------  -----  ---  ----
 1       null        1      0    1    14
 2          1        1      1    2     7
 3          2        1      2    3     4
 4          2        1      2    5     6
 5          1        1      1    8    13
 6          5        1      2    9    10
 7          5        1      2    11   12

Which describes a tree which looks like this (with id representing each item):

 1
 +-- 2
 |   +-- 3
 |   +-- 4
 |
 +-- 5
     +-- 6
     +-- 7

Or, as a nested set diagram which makes it more obvious how the lft and rght values work:

 __________________________________________________________________________
|  Root 1                                                                  |
|   ________________________________    ________________________________   |
|  |  Child 1.1                     |  |  Child 1.2                     |  |
|  |   ___________    ___________   |  |   ___________    ___________   |  |
|  |  |  C 1.1.1  |  |  C 1.1.2  |  |  |  |  C 1.2.1  |  |  C 1.2.2  |  |  |
1  2  3___________4  5___________6  7  8  9___________10 11__________12 13 14
|  |________________________________|  |________________________________|  |
|__________________________________________________________________________|

As you can see, to get the entire subtree for a given node, in tree order, you simply have to select all rows which have lft and rght values between its lft and rght values. It's also simple to retrieve the tree of ancestors for a given node.

The level column is a bit of denormalisation for convenience more than anything and the tree_id column allows you to restart the lft and rght numbering for each top-level node, which reduces the number of columns affected by inserts, moves and deletions, as the lft and rght columns have to be adjusted accordingly when these operations take place in order to create or close gaps. I made some development notes at the time when I was trying to wrap my head around the queries required for each operation.

In terms of actually working with this data to display a tree, I created a tree_item_iterator utility function which, for each node, should give you sufficient information to generate whatever kind of display you want.

instead of using " + " operator

print( "Alireza" + 1980)

Use comma " , " operator

print( "Alireza" , 1980)

Here are two other software packages which can be used for DNS caching on Linux:

• dnsmasq
• bind

After configuring the software for DNS forwarding and caching, you then set the system's DNS resolver to 127.0.0.1 in /etc/resolv.conf.

If your system is using NetworkManager you can either try using the dns=dnsmasq option in /etc/NetworkManager/NetworkManager.conf or you can change your connection settings to Automatic (Address Only) and then use a script in the /etc/NetworkManager/dispatcher.d directory to get the DHCP nameserver, set it as the DNS forwarding server in your DNS cache software and then trigger a configuration reload.

Here an implementation that uses a System.Threading.Timer. Maybe a bit much for its purpose.

    private static bool StartProcess(string filePath, string processName)
    {
        if (!File.Exists(filePath))
            throw new InvalidOperationException($"Unknown filepath: {(string.IsNullOrEmpty(filePath) ? "EMPTY PATH" : filePath)}");

        var isRunning = false;

        using (var resetEvent = new ManualResetEvent(false))
        {

            void Callback(object state)
            {
                if (!IsProcessActive(processName)) return;
                isRunning = true;
                // ReSharper disable once AccessToDisposedClosure
                resetEvent.Set();
            }

            using (new Timer(Callback, null, 0, TimeSpan.FromSeconds(0.5).Milliseconds))
            {
                Process.Start(filePath);
                WaitHandle.WaitAny(new WaitHandle[] { resetEvent }, TimeSpan.FromSeconds(9));
            }
        }

        return isRunning;
    }

    private static bool StopProcess(string processName)
    {
        if (!IsProcessActive(processName)) return true;

        var isRunning = true;

        using (var resetEvent = new ManualResetEvent(false))
        {

            void Callback(object state)
            {
                if (IsProcessActive(processName)) return;
                isRunning = false;
                // ReSharper disable once AccessToDisposedClosure
                resetEvent.Set();
            }

            using (new Timer(Callback, null, 0, TimeSpan.FromSeconds(0.5).Milliseconds))
            {
                foreach (var process in Process.GetProcessesByName(processName))
                    process.Kill();
                WaitHandle.WaitAny(new WaitHandle[] { resetEvent }, TimeSpan.FromSeconds(9));
            }
        }

        return isRunning;
    }

    private static bool IsProcessActive(string processName)
    {
        return Process.GetProcessesByName(processName).Any();
    }

You can get the values for the width and height of the browser using the following:

$(window).height();
$(window).width();

To get notified when the browser is resized, use this bind callback:

$(window).resize(function() {
    // Do something
});

The following structure in docker-compose.yaml will allow you to have the Dockerfile in a subfolder from the root:

version: '3'
services:
  db:
    image: postgres:11
    environment:
      - PGDATA=/var/lib/postgresql/data/pgdata
    volumes:
      - postgres-data:/var/lib/postgresql/data
    ports:
      - 127.0.0.1:5432:5432
  **web:
    build: 
      context: ".."
      dockerfile: dockerfiles/Dockerfile**
    command: ...
...

Then, in your Dockerfile, which is in the same directory as docker-compose.yaml, you can do the following:

ENV APP_HOME /home

RUN mkdir -p ${APP_HOME}

# Copy the file to the directory in the container
COPY test.json ${APP_HOME}/test.json
COPY test.py ${APP_HOME}/test.py

# Browse to that directory created above
WORKDIR ${APP_HOME}

You can then run docker-compose from the parent directory like:

docker-compose -f .\dockerfiles\docker-compose.yaml build --no-cache

You want something like this maybe?

> push <- function(l, x) {
   lst <- get(l, parent.frame())
   lst[length(lst)+1] <- x
   assign(l, lst, envir=parent.frame())
 }
> a <- list(1,2)
> push('a', 6)
> a
[[1]]
[1] 1

[[2]]
[1] 2

[[3]]
[1] 6

It's not a very polite function (assigning to parent.frame() is kind of rude) but IIUYC it's what you're asking for.

Here is a version based on the accepted answer. It fixes two problems...

1. Improper disposing of the images.
2. Maintaining the aspect ratio of the image.

I found this tool to be fast and effective for both JPG and PNG files.

private static FileInfo CreateThumbnailImage(string imageFileName, string thumbnailFileName)
{
    const int thumbnailSize = 150;
    using (var image = Image.FromFile(imageFileName))
    {
        var imageHeight = image.Height;
        var imageWidth = image.Width;
        if (imageHeight > imageWidth)
        {
            imageWidth = (int) (((float) imageWidth / (float) imageHeight) * thumbnailSize);
            imageHeight = thumbnailSize;
        }
        else
        {
            imageHeight = (int) (((float) imageHeight / (float) imageWidth) * thumbnailSize);
            imageWidth = thumbnailSize;
        }

        using (var thumb = image.GetThumbnailImage(imageWidth, imageHeight, () => false, IntPtr.Zero))
            //Save off the new thumbnail
            thumb.Save(thumbnailFileName);
    }

    return new FileInfo(thumbnailFileName);
}

Add this option:

"bInfo": false

For someone who needs an explanation and an example of how to use a regxp in Eclipse. Here is my example illustrating the problem.

I want to rename

/download.mp4^lecture_id=271

to

/271.mp4

And there can be multiple of these.

Here is how it should be done.

Then hit find/replace button

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

Can you check value of i by putting logger or println(). and check with closing db conn at the end. Rest your code looks fine and it should work.

You're probably trying to run Python 3 file with Python 2 interpreter. Currently (as of 2019), python command defaults to Python 2 when both versions are installed, on Windows and most Linux distributions.

But in case you're indeed working on a Python 2 script, a not yet mentioned on this page solution is to resave the file in UTF-8+BOM encoding, that will add three special bytes to the start of the file, they will explicitly inform the Python interpreter (and your text editor) about the file encoding.

There really isn't a single "answer" to this question, but there are definitely some helpful concepts that can help you to come to a decision.

The first question that needs to be answered in your use case is "Do I want to use the system Python?" If you want to use the Python distributed with your operating system, then using the apt-get install method may be just fine. Depending on the operating system distribution method though, you still have to ask some more questions, such as "Do I want to install multiple versions of this package?" If the answer is yes, then it is probably not a good idea to use something like apt. Dpkg pretty much will just untar an archive at the root of the filesystem, so it is up to the package maintainer to make sure the package installs safely under very little assumptions. In the case of most debian packages, I would assume (someone can feel free to correct me here) that they simply untar and provide a top level package.

For example, say the package is "virtualenv", you'd end up with /usr/lib/python2.x/site-packages/virtualenv. If you install it with easy_install you'd get something like /usr/lib/python2.x/site-packages/virtualenv.egg-link that might point to /usr/lib/python2.x/site-packages/virtualenv-1.2-2.x.egg which may be a directory or zipped egg. Pip does something similar although it doesn't use eggs and instead will place the top level package directly in the lib directory.

I might be off on the paths, but the point is that each method takes into account different needs. This is why tools like virtualenv are helpful as they allow you to sandbox your Python libraries such that you can have any combination you need of libraries and versions.

Setuptools also allows installing packages as multiversion which means there is not a singular module_name.egg-link created. To import those packages you need to use pkg_resources and the __import__ function.

Going back to your original question, if you are happy with the system python and plan on using virtualenv and pip to build environments for different applications, then installing virtualenv and / or pip at the system level using apt-get seems totally appropriate. One word of caution though is that if you plan on upgrading your distributions Python, that may have a ripple effect through your virtualenvs if you linked back to your system site packages.

I should also mention that none of these options is inherently better than the others. They simply take different approaches. Using the system version is an excellent way to install Python applications, yet it can be a very difficult way to develop with Python. Easy install and setuptools is very convenient in a world without virtualenv, but if you need to use different versions of the same library, then it also become rather unwieldy. Pip and virtualenv really act more like a virtual machine. Instead of taking care to install things side by side, you just create an whole new environment. The downside here is that 30+ virtualenvs later you might have used up quite bit of diskspace and cluttered up your filesystem.

As you can see, with the many options it is difficult to say which method to use, but with a little investigation into your use cases, you should be able to find a method that works.

First of all find the python process ID using this command

ps -fA | grep python

You will get a pid number by naming of your python process on second column

Then kill the process using this command

kill -9 pid

In first statement you define variable, which common for all of the objects (class static field).

In the second statement you define variable, which belongs to each created object (a lot of copies).

In your case you should use the first one.

Can you use date as a factor?

Yes, but you probably shouldn't.

...or should you use as.Date on a date column?

Yes.

Which leads us to this:

library(scales)
df$Month <- as.Date(df$Month)
ggplot(df, aes(x = Month, y = AvgVisits)) + 
  geom_bar(stat = "identity") +
  theme_bw() +
  labs(x = "Month", y = "Average Visits per User") +
  scale_x_date(labels = date_format("%m-%Y"))

in which I've added stat = "identity" to your geom_bar call.

In addition, the message about the binwidth wasn't an error. An error will actually say "Error" in it, and similarly a warning will always say "Warning" in it. Otherwise it's just a message.

This error happens when the resource is busy. Check if you have any referential constraints in the query. Or even the tables that you have mentioned in the query may be busy. They might be engaged with some other job which will be definitely listed in the following query results:

SELECT * FROM V$SESSION WHERE STATUS = 'ACTIVE'

Find the SID,

SELECT * FROM V$OPEN_CURSOR WHERE SID = --the id

remove the ios::binary from your modes in your ofstream and use studentPassword.c_str() instead of (char *)&studentPassword in your write.write()

I have created some handy code snippets that'll create overloaded constructors as well. You're welcome to use them: https://github.com/ejbeaty/Power-Snippets

For example: 'ctor2' would create a constructor with two arguments and allow you to tab through them one by one like this:

public MyClass(ArgType argName, ArgType argName)
{

}

this is what you have to do.

decimal d = 1200.00;    
string value = d.ToString(CultureInfo.InvariantCulture);

// value = "1200.00" 

This worked for me. Thanks.

Here's a blog post that should help with escaping ticks in strings.

Here's the simplest method from said post:

The most simple and most used way is to use a single quotation mark with two single >quotation marks in both sides.

SELECT 'test single quote''' from dual;

The output of the above statement would be:

test single quote'

Simply stating you require an additional single quote character to print a single quote >character. That is if you put two single quote characters Oracle will print one. The first >one acts like an escape character.

This is the simplest way to print single quotation marks in Oracle. But it will get >complex when you have to print a set of quotation marks instead of just one. In this >situation the following method works fine. But it requires some more typing labour.

You don't need an index match formula. You can use this array formula. You have to press CTL + SHIFT + ENTER after you enter the formula.

=MAX(IF((A1:A6=A10)*(B1:B6=B10),C1:F6))
