My final solution

class DynamicModeTabLayout : TabLayout {

    constructor(context: Context?) : super(context)
    constructor(context: Context?, attrs: AttributeSet?) : super(context, attrs)
    constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr)

    override fun setupWithViewPager(viewPager: ViewPager?) {
        super.setupWithViewPager(viewPager)

        val view = getChildAt(0) ?: return
        view.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED)
        val size = view.measuredWidth

        if (size > measuredWidth) {
            tabMode = MODE_SCROLLABLE
            tabGravity = GRAVITY_CENTER
        } else {
            tabMode = MODE_FIXED
            tabGravity = GRAVITY_FILL
        }
    }
}

textView.setGravity(Gravity.CENTER | Gravity.BOTTOM);

This will set gravity of your textview.

We can align a view in center of the FrameLayout by setting the layout_gravity of the child view.

In XML:

android:layout_gravity="center"

In Java code:

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.CENTER;

Note: use FrameLayout.LayoutParams not the others existing LayoutParams

You can use max(value, run)

The function max takes any number of arguments, or (alternatively) an iterable, and returns the maximum value.

I got

No 'Access-Control-Allow-Origin' header is present

and the problem was with the URL I was providing. I was providing the URL without a route, e.g., https://misty-valley-1234.herokuapp.com/.

When I added a path it worked, e.g., https://misty-valley-1234.herokuapp.com/messages. With GET requests it worked either way but with POST responses it only worked with the added path.

This is very simple. Add a button in the layout file like

<Button
   android:layout_width="200dp"
   android:layout_height="wrap_content"
   android:text="Login with facebook"
   android:textColor="#ffff"
   android:layout_gravity="center"
   android:textStyle="bold"
   android:onClick="fbLogin"
   android:background="@color/colorPrimary"/>

And in the onClick place the LoginManager's registercallback() method Becuse the this method automatically executes.

  public void fbLogin(View view)
{
    LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("user_photos", "email", "public_profile", "user_posts" , "AccessToken"));
    LoginManager.getInstance().logInWithPublishPermissions(this, Arrays.asList("publish_actions"));
    LoginManager.getInstance().registerCallback(callbackManager,
            new FacebookCallback<LoginResult>()
            {
                @Override
                public void onSuccess(LoginResult loginResult)
                {
                    // App code
                }

                @Override
                public void onCancel()
                {
                    // App code
                }

                @Override
                public void onError(FacebookException exception)
                {
                    // App code
                }
            });
}

Assuming that your table is called 'Table1' and the column you need is 'Column' you can try this:

for i = 1 to Range("Table1").Rows.Count
   Range("Table1[Column]")(i)="PHEV"
next i

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]
public ActionResult Foo(string id)
{
    var person = Something.GetPersonByID(id);
    return Json(person, JsonRequestBehavior.AllowGet);
}

Jquery GET

function getPerson(id) {
    $.ajax({
        url: '@Url.Action("Foo", "SomeController")',
        type: 'GET',
        dataType: 'json',
        // we set cache: false because GET requests are often cached by browsers
        // IE is particularly aggressive in that respect
        cache: false,
        data: { id: id },
        success: function(person) {
            $('#FirstName').val(person.FirstName);
            $('#LastName').val(person.LastName);
        }
    });
}

Person class

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Method 2 : Using jQuery Ajax Post call (partial page update).

Suitable for when you need to do partial page post data into database.

Post method is also same like above just replace [HttpPost] on Action method and type as post for jquery method.

For more information check Posting JSON Data to MVC Controllers Here

Method 3 : As a Form post scenario (full page update).

Suitable for when you need to save or update data into database.

View

@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{        
    @Html.TextBoxFor(model => m.Text)
    
    <input type="submit" value="Save" />
}

Action Method

[HttpPost]
public ActionResult SaveData(FormCollection form)
    {
        // Get movie to update
        return View();
   }

Method 4 : As a Form Get scenario (full page update).

Suitable for when you need to Get data from database

Get method also same like above just replace [HttpGet] on Action method and FormMethod.Get for View's form method.

I hope this will help to you.

You should read Supporting multiple screens. You must define dpi on your emulator. 240 is hdpi, 160 is mdpi and below that are usually ldpi.

Extract from Android Developer Guide link above:

320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).  
480dp: a tweener tablet like the Streak (480x800 mdpi).  
600dp: a 7” tablet (600x1024 mdpi).  
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

You can use the jQuery Color plugin.

For example, to draw attention to all the divs on your page, you could use the following code:

$("div").stop().css("background-color", "#FFFF9C")
    .animate({ backgroundColor: "#FFFFFF"}, 1500);

Edit - New and improved

The following uses the same technique as above, but it has the added benefits of:

• parameterized highlight color and duration
• retaining original background color, instead of assuming that it is white
• being an extension of jQuery, so you can use it on any object

Extend the jQuery Object:

var notLocked = true;
$.fn.animateHighlight = function(highlightColor, duration) {
    var highlightBg = highlightColor || "#FFFF9C";
    var animateMs = duration || 1500;
    var originalBg = this.css("backgroundColor");
    if (notLocked) {
        notLocked = false;
        this.stop().css("background-color", highlightBg)
            .animate({backgroundColor: originalBg}, animateMs);
        setTimeout( function() { notLocked = true; }, animateMs);
    }
};

Usage example:

$("div").animateHighlight("#dd0000", 1000);

Scanner sc = new Scanner(System.in); 
String name = sc.nextLine();
String surname = sc.nextLine();
Statement statement = connection.createStatement();
String query = "INSERT INTO STUDENT VALUES("+'"name"'+","+'"surname"'+")";
statement.executeQuery();

Do not miss to add '"----"' when concat the string.

This should help:

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

Here's what I ended up using.

public class DataPoint<T1,T2>
{
    public DataPoint(T1 x, T2 y)
    {
        X = x;
        Y = y;
    }

    [JsonProperty("x")]
    public T1 X { get; }

    [JsonProperty("y")]
    public T2 Y { get; }
}

public class Trendline
{
    public Trendline(IEnumerable<DataPoint<long, decimal>> dataPoints)
    {
        int count = 0;
        long sumX = 0;
        long sumX2 = 0;
        decimal sumY = 0;
        decimal sumXY = 0;

        foreach (var dataPoint in dataPoints)
        {
            count++;
            sumX += dataPoint.X;
            sumX2 += dataPoint.X * dataPoint.X;
            sumY += dataPoint.Y;
            sumXY += dataPoint.X * dataPoint.Y;
        }

        Slope = (sumXY - ((sumX * sumY) / count)) / (sumX2 - ((sumX * sumX) / count));
        Intercept = (sumY / count) - (Slope * (sumX / count));
    }

    public decimal Slope { get; private set; }
    public decimal Intercept { get; private set; }
    public decimal Start { get; private set; }
    public decimal End { get; private set; }

    public decimal GetYValue(decimal xValue)
    {
        return Slope * xValue + Intercept;
    }
}

My data set is using a Unix timestamp for the x-axis and a decimal for the y. Change those datatypes to fit your need. I do all the sum calculations in one iteration for the best possible performance.

According to the select_list Oracle select documentation the AS is optional.

As a personal note I think it is easier to read with the AS

I use an extension method for this. My extension method first checks to see if the enumeration is null and if so creates an empty list. This allows you to do a foreach on it without explicitly having to check for null.

Here is a very contrived example:

IEnumerable<string> stringEnumerable = null;
StringBuilder csv = new StringBuilder();
stringEnumerable.ToNonNullList().ForEach(str=> csv.Append(str).Append(","));

Here is the extension method:

public static List<T> ToNonNullList<T>(this IEnumerable<T> obj)
{
    return obj == null ? new List<T>() : obj.ToList();
}

svn rm --keep-local folder_name

Note: In svn 1.5.4 svn rm deletes unversioned files even when --keep-local is specified. See http://svn.haxx.se/users/archive-2009-11/0058.shtml for more information.

It seems the answers here do not support an enterprise use case where a Nexus server has multiple users and has project-based isolation (protection) based on user id ALONG with using an automated build (CI) system like Jenkins. You would not be able to create a settings.xml file to satisfy the different user ids needed for different projects. I am not sure how to solve this, except by opening Nexus up to anonymous access for reading repositories, unless the projects could store a project-specific generic user id in their pom.xml.

You can use a vector. Instead of worry about different screen sizes you only need to create an .svg file and import it to your project using Vector Asset Studio.

import it in your class

import org.apache.commons.lang.StringUtils;

then use it, they both will return true

System.out.println(StringUtils.isEmpty(""));
System.out.println(StringUtils.isEmpty(null)); 

I used the following for a drawable image with a circular background.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/colorAccent"/>
        </shape>
    </item>
    <item
        android:drawable="@drawable/ic_select"
        android:bottom="20dp"
        android:left="20dp"
        android:right="20dp"
        android:top="20dp"/>
</layer-list>

Here is what it looks like

Hope that helps someone out.

If it's a percentage width, then yes, it is respected. As Martin pointed out, things break down when you get to fractional pixels, but if your percentage values yield integer pixel value (e.g. 50.5% of 200px in the example) you'll get sensible, expected behaviour.

Edit: I've updated the example to show what happens to fractional pixels (in Chrome the values are truncated, so 50, 50.5 and 50.6 all show the same width).

tags = [u'man', u'you', u'are', u'awesome']
entries = [[u'man', u'thats'],[ u'right',u'awesome']]

result = []
[result.extend(entry) for tag in tags for entry in entries if tag in entry]

print(result)

Output:

['man', 'thats', 'right', 'awesome']

clearfix is the same as overflow:hidden. Both clear floated children of the parent, but clearfix will not cut off the element which overflow to it's parent. It also works in IE8 & above.

There is no need to define "." in content & .clearfix. Just write like this:

.clr:after {
    clear: both;
    content: "";
    display: block;
}

HTML

<div class="parent clr"></div>

What methods of ‘clearfix’ can I use?

No need to use a lot of CSS, just use bootstrap, then use:

class="container"

for the div that needs to be filled.

You can get bootstrap from here

Yes, there is a module fs-extra. There is a method .emptyDir() inside this module which does the job. Here is an example:

const fsExtra = require('fs-extra')

fsExtra.emptyDirSync(fileDir)

There is also an asynchronous version of this module too. Anyone can check out the link.

My ajax never gets fired until I wrapped the whole thing in

setTimeout(function(){ .... }, 3000);

I was using it in mounted section of Vue. it needs more time.

Essentially you are including the font into your project.

@font-face {
font-family: 'Open Sans';
font-style: normal;
font-weight: normal;
src: url('path/to/OpenSans.eot');
src: local('Open Sans'), local('OpenSans'), url('path/to/OpenSans.ttf') format('truetype');

You have a few options:

• Release an update for your app that uses a different hostname that isn't in anyone's cache.
• Same thing, but using the IP address of your server
• Have your users go into settings -> applications -> Network Location -> Clear data.

You may want to check that last step because i don't know for a fact that this is the appropriate service. I can't really test that right now. Good luck!

A low-tech approach: Doing this with SQL might be overkill. According to your question you just need to do a one-time verification of the import.

Why not just do: SELECT * FROM ImportTable

and then scroll to the bottom of the results grid and visually verify the "last" few lines.

Seems like one of your values, with a property key of 'value' is undefined. Test that i1, i2and __i are defined before executing the if statements:

var i1 = document.getElementById('i1');
var i2 = document.getElementById('i2');
var __i = {'user' : document.getElementsByName("username")[0], 'pass' : document.getElementsByName("password")[0] };
if(i1 && i2 && __i.user && __i.pass)
{
    if(  __i.user.value.length >= 1 ) { i1.value = ''; } else { i1.value = 'Acc'; }

    if(  __i.pass.value.length >= 1 ) { i2.value = ''; } else { i2.value = 'Pwd'; }
}

In the mid 90’s I worked in a small management consulting firm using a GIS product called MapInfo which had a weak scripting language called MapBasic.

I don’t remember the specifics, but basically at that time there were objects* which could only be instantiated when hard coded (as opposed to instantiating with variables). This was a total pain in that it appeared to do everything you needed done, until you actually attempted to implement. Implementation was either impossible or very kludge heavy.

I was a novice at that point and had a lot of difficulty a) predicting what could and could not be done, and b) explaining why to my non-programming manager. It was frustrating none the less.

There are a lot of languages and tools which are weak in certain areas, but after dealing with Map Basic, even Visual Basic 3.0 felt liberating!

*-I don’t remember if it was all objects or only certain ones.

Try adding this method to a class and see if you still get the error:

[STAThread]
static void Main()
{
}

This code is better.

public static  byte[] getByteArrayFromImageView(ImageView imageView)
    {
        BitmapDrawable bitmapDrawable = ((BitmapDrawable) imageView.getDrawable());
        Bitmap bitmap;
        if(bitmapDrawable==null){
            imageView.buildDrawingCache();
            bitmap = imageView.getDrawingCache();
            imageView.buildDrawingCache(false);
        }else
        {
            bitmap = bitmapDrawable .getBitmap();
        }
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        return stream.toByteArray();
    }

A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.

For instance, place your property file in a new folder src/main/config, and add the following to your pom:

 <build>
    <resources>
        <resource>
            <directory>src/main/config</directory>
        </resource>
    </resources>
 </build>

From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <excludes>
                    <exclude>my-config.properties</exclude>
                </excludes>
            </configuration>
        </plugin>
    </plugins>

so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).

I am a .NET developer, and have used Git and Visual Studio for years. My strong recommendation is set line endings to true. And do it as early as you can in the lifetime of your Repository.

That being said, I HATE that Git changes my line endings. A source control should only save and retrieve the work I do, it should NOT modify it. Ever. But it does.

What will happen if you don't have every developer set to true, is ONE developer eventually will set to true. This will begin to change the line endings of all of your files to LF in your repo. And when users set to false check those out, Visual Studio will warn you, and ask you to change them. You will have 2 things happen very quickly. One, you will get more and more of those warnings, the bigger your team the more you get. The second, and worse thing, is that it will show that every line of every modified file was changed(because the line endings of every line will be changed by the true guy). Eventually you won't be able to track changes in your repo reliably anymore. It is MUCH easier and cleaner to make everyone keep to true, than to try to keep everyone false. As horrible as it is to live with the fact that your trusted source control is doing something it should not. Ever.

Pass the datable to this method it would return json String.

public DataTable GetTable()
        {
            string str = "Select * from GL_V";
            OracleCommand cmd = new OracleCommand(str, con);
            cmd.CommandType = CommandType.Text;
            DataTable Dt = OracleHelper.GetDataSet(con, cmd).Tables[0];

            return Dt;
        }

        public string DataTableToJSONWithJSONNet(DataTable table)
        {
            string JSONString = string.Empty;
            JSONString = JsonConvert.SerializeObject(table);
            return JSONString;
        }



public static DataSet GetDataSet(OracleConnection con, OracleCommand cmd)
        {
            // create the data set  
            DataSet ds = new DataSet();
            try

                //checking current connection state is open
                if (con.State != ConnectionState.Open)
                    con.Open();

                // create a data adapter to use with the data set
                OracleDataAdapter da = new OracleDataAdapter(cmd);

                // fill the data set
                da.Fill(ds);
            }
            catch (Exception ex)

            }
            return ds;
        }

You need to be aware that month is zero based so when you do the getMonth you will need to add 1. In the example below we have to add 1 to Januaray as 1 and not 0

    Calendar c = Calendar.getInstance();
    c.set(2011, 2, 1);
    c.add(Calendar.MONTH, -1);
    int month = c.get(Calendar.MONTH) + 1;
    assertEquals(1, month);

You need to use a constant.

CONST NumberOfZombies = 20000
Dim Zombies(NumberOfZombies) As Zombies

or if you want to use a variable you have to do it this way:

Dim NumberOfZombies As Integer
NumberOfZombies = 20000

Dim Zombies() As Zombies

ReDim Zombies(NumberOfZombies)

Yes, on a 32bit machine the maximum amount of memory usable is around 4GB. Actually, depending on the OS it might be less due to parts of the address space being reserved: On Windows you can only use 3.5GB for example.

On 64bit you can indeed address 2^64 bytes of memory. Not that you'll ever have those - but then again, a long time ago the same thing was said about ever needing more than 640kb of memory...

Notepad++ provides 2 types of features:

• Auto-completion that read the open file and provide suggestion of words and/or functions within the file
• Suggestion with the arguments of functions (specific to the language)

Based on what you write, it seems what you want is auto-completion on function only + suggestion on arguments.

To do that, you just need to change a setting.

1. Go to Settings > Preferences... > Auto-completion
2. Check Enable Auto-completion on each input
3. Select Function completion and not Word completion
4. Check Function parameter hint on input (if you have this option)

On version 6.5.5 of Notepad++, I have this setting

Some documentation about auto-completion is available in Notepad++ Wiki.

try

location = url;

onclick="location='https://example.com'" />_x000D_
_x000D_
<input type="button" value="URL()" _x000D_
onclick="url()" />

I had the same error. What worked for me is when you go for the SMSS GUI option, look at General, Files in Options settings. After I did that (replace DB, set location) all went well.

In Java 9, if you have an object which has another object as property and that nested objects has a method yielding a string, then you can use this construct to return an empty string if the embeded object is null :

String label = Optional.ofNullable(org.getDiffusion()).map(Diffusion::getLabel).orElse("")

In this example :

• org is an instance of an object of type Organism
• Organism has a Diffusion property (another object)
• Diffusion has a String label property (and getLabel() getter).

With this example, if org.getDiffusion() is not null, then it returns the getLabel property of its Diffusion object (this returns a String). Otherwise, it returns an empty string.

To perform a linear regression between two vectors x and y follow these steps:

[p,err] = polyfit(x,y,1);   % First order polynomial
y_fit = polyval(p,x,err);   % Values on a line
y_dif = y - y_fit;          % y value difference (residuals)
SSdif = sum(y_dif.^2);      % Sum square of difference
SStot = (length(y)-1)*var(y);   % Sum square of y taken from variance
rsq = 1-SSdif/SStot;        % Correlation 'r' value. If 1.0 the correlelation is perfect

For x=[10;200;7;150] and y=[0.001;0.45;0.0007;0.2] I get rsq = 0.9181.

Check if npm config production value is set to true. If this value is true, it will skip over the dev dependencies.

Run npm config get production

To set it: npm config set -g production false

You don't only need the header file, you need the library that goes with it. Anyway, the include folder is not automatically loaded, you must configure your project to do so. Right-click on it : Build options > Search directories > Add. Choose your include folder, keep the path relative.

Edit For further assistance, please give details about the library you're trying to load (which provides a graphics.h file.)

Or to build upon what Jar Jar suggested, this is what I used on a recent project (to overcome length restrictions):

var randomString = function (len, bits)
{
    bits = bits || 36;
    var outStr = "", newStr;
    while (outStr.length < len)
    {
        newStr = Math.random().toString(bits).slice(2);
        outStr += newStr.slice(0, Math.min(newStr.length, (len - outStr.length)));
    }
    return outStr.toUpperCase();
};

Use:

randomString(12, 16); // 12 hexadecimal characters
randomString(200); // 200 alphanumeric characters

The mPDF docs state that the first argument of Output() is the file path, second is the saving mode - you need to set it to 'F'.

$mpdf->Output('filename.pdf','F');

As said above getch() is in the ncurses library. ncurses has to be initialized, see i.e. getchar() returns the same value (27) for up and down arrow keys for this

I was facing problem with Ngx line chart xAxisTickFormatting function which was called from HTML like this: [xAxisTickFormatting]="xFormat". I was unable to access my component's variable from the function declared. This solution helped me to resolve the issue to find the correct this. Hope this helps the Ngx line chart, users.

instead of using the function like this:

xFormat (value): string {
  return value.toString() + this.oneComponentVariable; //gives wrong result 
}

Use this:

 xFormat = (value) => {
   // console.log(this);
   // now you have access to your component variables
   return value + this.oneComponentVariable
 }

Made a simple implementation of what I believe to be what you want to achieve. You can use the class later with the following arguments:

• int (milliseconds to wait until to run the code)
• bool (if true it returns instantly and runs the code after specified time on another thread)
• variable arguments (exactly what you'd feed to std::bind)

You can change std::chrono::milliseconds to std::chrono::nanoseconds or microseconds for even higher precision and add a second int and a for loop to specify for how many times to run the code.

Here you go, enjoy:

#include <functional>
#include <chrono>
#include <future>
#include <cstdio>

class later
{
public:
    template <class callable, class... arguments>
    later(int after, bool async, callable&& f, arguments&&... args)
    {
        std::function<typename std::result_of<callable(arguments...)>::type()> task(std::bind(std::forward<callable>(f), std::forward<arguments>(args)...));

        if (async)
        {
            std::thread([after, task]() {
                std::this_thread::sleep_for(std::chrono::milliseconds(after));
                task();
            }).detach();
        }
        else
        {
            std::this_thread::sleep_for(std::chrono::milliseconds(after));
            task();
        }
    }

};

void test1(void)
{
    return;
}

void test2(int a)
{
    printf("%i\n", a);
    return;
}

int main()
{
    later later_test1(1000, false, &test1);
    later later_test2(1000, false, &test2, 101);

    return 0;
}

Outputs after two seconds:

101

Use counting sort and then find the second largest element, starting from index 0 towards the end. There should be at least 1 comparison, at most n-1 (when there's only one element!).

Depending on size and scale of the difficultly, you could create a scratch (temporary) branch and commit the current work there.

Then switch to and checkout your original branch, and pick the appropriate files from the scratch commit.

At least you would have a permanent record of the current and previous states to work from (until you delete that scratch branch).

I am thinking this may not be possible in Java because annotation and its parameters are resolved at compile time.

With Seam 2 http://seamframework.org/ you were able to resolve annotation parameters at runtime, with expression language inside double quotes.

In Seam 3 http://seamframework.org/Seam3/Solder, this feature is the module Seam Solder

Another way to do this without jQuery would be to use Greensock's TweenLite JS library.

Demo http://codepen.io/anon/pen/yNWwEJ

var display = document.getElementById("display");
var number = {param:0};
var duration = 1;

function count() {
  TweenLite.to(number, duration, {param:"+=20", roundProps:"param",
  onUpdate:update, onComplete:complete, ease:Linear.easeNone});
}

function update() {
  display.innerHTML = number.param;
}

function complete() {
  //alert("Complete");
}

count();

When the compiler compiles the class User and gets to the MyMessageBox line, MyMessageBox has not yet been defined. The compiler has no idea MyMessageBox exists, so cannot understand the meaning of your class member.

You need to make sure MyMessageBox is defined before you use it as a member. This is solved by reversing the definition order. However, you have a cyclic dependency: if you move MyMessageBox above User, then in the definition of MyMessageBox the name User won't be defined!

What you can do is forward declare User; that is, declare it but don't define it. During compilation, a type that is declared but not defined is called an incomplete type. Consider the simpler example:

struct foo; // foo is *declared* to be a struct, but that struct is not yet defined

struct bar
{
    // this is okay, it's just a pointer;
    // we can point to something without knowing how that something is defined
    foo* fp; 

    // likewise, we can form a reference to it
    void some_func(foo& fr);

    // but this would be an error, as before, because it requires a definition
    /* foo fooMember; */
};

struct foo // okay, now define foo!
{
    int fooInt;
    double fooDouble;
};

void bar::some_func(foo& fr)
{
    // now that foo is defined, we can read that reference:
    fr.fooInt = 111605;
    fr.foDouble = 123.456;
}

By forward declaring User, MyMessageBox can still form a pointer or reference to it:

class User; // let the compiler know such a class will be defined

class MyMessageBox
{
public:
    // this is ok, no definitions needed yet for User (or Message)
    void sendMessage(Message *msg, User *recvr); 

    Message receiveMessage();
    vector<Message>* dataMessageList;
};

class User
{
public:
    // also ok, since it's now defined
    MyMessageBox dataMsgBox;
};

You cannot do this the other way around: as mentioned, a class member needs to have a definition. (The reason is that the compiler needs to know how much memory User takes up, and to know that it needs to know the size of its members.) If you were to say:

class MyMessageBox;

class User
{
public:
    // size not available! it's an incomplete type
    MyMessageBox dataMsgBox;
};

It wouldn't work, since it doesn't know the size yet.

On a side note, this function:

 void sendMessage(Message *msg, User *recvr);

Probably shouldn't take either of those by pointer. You can't send a message without a message, nor can you send a message without a user to send it to. And both of those situations are expressible by passing null as an argument to either parameter (null is a perfectly valid pointer value!)

Rather, use a reference (possibly const):

 void sendMessage(const Message& msg, User& recvr);

Here is a great article using Restkit

It explains on serializing nested data into JSON and attaching the data to a HTTP POST request.

When you created the WebForm, did you select the Master page it is attached to in the "Add New Item" dialog itself ? Or did you attach it manually using the MasterPageFile attribute of the @Page directive ? If it was the latter, it might explain the error message you receive.

VS automatically inserts certain markup in each kind of page. If you select the MasterPage at the time of page creation itself, it does not generate any markup except the @Page declaration and the top level Content control.

Yes, as other answers have states, it cannot be done with Write-Output. Where PowerShell fails, turn to .NET, there are even a couple of .NET answers here but they are more complex than they need to be.

Just use:

[Console]::Write("Enabling feature XYZ.......")
Enable-SPFeature...
Write-Output "Done"

It is not purest PowerShell, but it works.

I had the same issue. But in my case it was due to my branch's name. The branch's name automatically set in my GitHub repo as main instead of master.

git pull origin master (did not work).

I confirmed in GitHub if the name of the branch was actually master and found the the actual name was main. so the commands below worked for me. git pull origin main

Mesos and Kubernetes can both be used to manage a cluster of machines and abstract away the hardware.

Mesos, by design, doesn't provide you with a scheduler (to decide where and when to run processes and what to do if the process fails), you can use something like Marathon or Chronos, or write your own.

Kubernetes will do scheduling for you out of the box, and can be used as a scheduler for Mesos (please correct me if I'm wrong here!) which is where you can use them together. Mesos can have multiple schedulers sharing the same cluster, so in theory you could run kubernetes and chronos together on the same hardware.

Super simplistically: if you want control over how your containers are scheduled, go for Mesos, otherwise Kubernetes rocks.

Just for the shake of completing the answer given by eipi10.

I was facing the same problem, without using scale_y_continuous nor coord_cartesian.

The conflict was coming from the x axis, where I defined limits = c(1, 30). It seems such limits do not provide enough space if you want to "dodge" your bars, so R still throws the error

Removed 8 rows containing missing values (geom_bar)

Adjusting the limits of the x axis to limits = c(0, 31) solved the problem.

In conclusion, even if you are not putting limits to your y axis, check out your x axis' behavior to ensure you have enough space

If You are trying to access it through Data Connections in Visual Studio 2015, and getting the above Error, Then Go to Advanced and set TrustServerCertificate=True for error to go away.

You can try df.column_name = df.column_name.astype(float). As for the NaN values, you need to specify how they should be converted, but you can use the .fillna method to do it.

Example:

In [12]: df
Out[12]: 
     a    b
0  0.1  0.2
1  NaN  0.3
2  0.4  0.5

In [13]: df.a.values
Out[13]: array(['0.1', nan, '0.4'], dtype=object)

In [14]: df.a = df.a.astype(float).fillna(0.0)

In [15]: df
Out[15]: 
     a    b
0  0.1  0.2
1  0.0  0.3
2  0.4  0.5

In [16]: df.a.values
Out[16]: array([ 0.1,  0. ,  0.4])

getUserRootFolder() {
  return process.env.HOME || process.env.HOMEPATH || process.env.USERPROFILE;
}

Attribute is a synonym of field for array.length

To answer your original question:

def namestr(obj, namespace):
    return [name for name in namespace if namespace[name] is obj]

Example:

>>> a = 'some var'
>>> namestr(a, globals())
['a']

As @rbright already pointed out whatever you do there are probably better ways to do it.

I just wanted to add, that if you use CloudFlare (free), you can use their API to manage your dns with ease.

To install specific version of laravel try this & simply command on terminal

composer create-project --prefer-dist laravel/laravel:5.5.0 {dir-name}

Another jQuery cross-browser solution for this problem is http://designwithpc.com/Plugins/ddSlick which is made for exactly this use.

Change duration and opacity to suit.

.blink_text { 
    -webkit-animation-name: blinker;
    -webkit-animation-duration: 3s;
    -webkit-animation-timing-function: linear;
    -webkit-animation-iteration-count: infinite;
    -moz-animation-name: blinker;
    -moz-animation-duration: 3s;
    -moz-animation-timing-function: linear;
    -moz-animation-iteration-count: infinite;
    animation-name: blinker;
    animation-duration: 3s;
    animation-timing-function: linear; 
    animation-iteration-count: infinite; color: red; 
} 

@-moz-keyframes blinker {
    0% { opacity: 1.0; }
    50% { opacity: 0.3; }
    100% { opacity: 1.0; } 
}

@-webkit-keyframes blinker { 
    0% { opacity: 1.0; }
    50% { opacity: 0.3; }
    100% { opacity: 1.0; } 
} 

@keyframes blinker { 
    0% { opacity: 1.0; } 
    50% { opacity: 0.3; } 
    100% { opacity: 1.0; }

There's a class called SoapHexBinary that does exactly what you want.

using System.Runtime.Remoting.Metadata.W3cXsd2001;

public static byte[] GetStringToBytes(string value)
{
    SoapHexBinary shb = SoapHexBinary.Parse(value);
    return shb.Value;
}

public static string GetBytesToString(byte[] value)
{
    SoapHexBinary shb = new SoapHexBinary(value);
    return shb.ToString();
}

The trick of appending "*" can be made to work when the new extension is shorter. You need to pad the new extension with blanks, which can only be done by enclosing the destination file name in quotes. For example:

xcopy foo.shtml "foo.html *"

This will copy and rename without prompting.

"That's not a bug, it's a feature!" (I once saw a VW Beetle in the Microsoft parking lot with the vanity plate "FEATURE".) These semantics for rename go all the way back to when I wrote DOS v.1. Characters in the new name are substituted one by one for characters in the old name, unless a wildcard character (? or *) is present in the new name. Without adding the blank(s) to the new name, remaining characters are copied from the old name.

With a simple generic function you can make this very easy. Just do this:

return ConvertFromDBVal<string>(accountNumber);

using the function:

public static T ConvertFromDBVal<T>(object obj)
{
    if (obj == null || obj == DBNull.Value)
    {
        return default(T); // returns the default value for the type
    }
    else
    {
        return (T)obj;
    }
}

You should either use

if str1[0] == '"' and str1[-1] == '"'

or

if str1.startswith('"') and str1.endswith('"')

but not slice and check startswith/endswith together, otherwise you'll slice off what you're looking for...

The Abstract Factory Pattern

• Provide an interface for creating families of related or dependent objects without specifying their concrete classes.

• The Abstract Factory pattern is very similar to the Factory Method pattern. One difference between the two is that with the Abstract Factory pattern, a class delegates the responsibility of object instantiation to another object via composition whereas the Factory Method pattern uses inheritance and relies on a subclass to handle the desired object instantiation.

• Actually, the delegated object frequently uses factory methods to perform the instantiation!

Factory pattern

• Factory patterns are examples of creational patterns

• Creational patterns abstract the object instantiation process. They hide how objects are created and help make the overall system independent of how its objects are created and composed.

• Class creational patterns focus on the use of inheritance to decide the object to be instantiated Factory Method

• Object creational patterns focus on the delegation of the instantiation to another object Abstract Factory

Reference: Factory vs Abstract Factory

Use struct.pack to convert the integer values into binary bytes, then write the bytes. E.g.

newFile.write(struct.pack('5B', *newFileBytes))

However I would never give a binary file a .txt extension.

The benefit of this method is that it works for other types as well, for example if any of the values were greater than 255 you could use '5i' for the format instead to get full 32-bit integers.

XHTML 1 specification says:

?.3. Element Minimization and Empty Element Content

Given an empty instance of an element whose content model is not EMPTY (for example, an empty title or paragraph) do not use the minimized form (e.g. use <p> </p> and not <p />).

XHTML DTD specifies script elements as:

<!-- script statements, which may include CDATA sections -->
<!ELEMENT script (#PCDATA)>

Not portable, Zsh only, but pretty concise.

First, make sure zmv is loaded.

autoload -U zmv

Also, make sure extendedglob is on:

setopt extendedglob

Then use:

zmv '(**/)(*)~CVS~**/CVS' '${1}${(L)2}'

To recursively lowercase files and directories where the name is not CVS.

For us VBers:

TrimEnd(New Char() {ControlChars.Cr, ControlChars.Lf})

I would recommend you using the Conditional Attribute!

Update: 3.5 years later

You can use #if like this (example copied from MSDN):

// preprocessor_if.cs
#define DEBUG
#define VC_V7
using System;
public class MyClass 
{
    static void Main() 
    {
#if (DEBUG && !VC_V7)
        Console.WriteLine("DEBUG is defined");
#elif (!DEBUG && VC_V7)
        Console.WriteLine("VC_V7 is defined");
#elif (DEBUG && VC_V7)
        Console.WriteLine("DEBUG and VC_V7 are defined");
#else
        Console.WriteLine("DEBUG and VC_V7 are not defined");
#endif
    }
}

Only useful for excluding parts of methods.

If you use #if to exclude some method from compilation then you will have to exclude from compilation all pieces of code which call that method as well (sometimes you may load some classes at runtime and you cannot find the caller with "Find all references"). Otherwise there will be errors.

If you use conditional compilation on the other hand you can still leave all pieces of code that call the method. All parameters will still be validated by the compiler. The method just won't be called at runtime. I think that it is way better to hide the method just once and not have to remove all the code that calls it as well. You are not allowed to use the conditional attribute on methods which return value - only on void methods. But I don't think this is a big limitation because if you use #if with a method that returns a value you have to hide all pieces of code that call it too.

Here is an example:

    // calling Class1.ConditionalMethod() will be ignored at runtime 
    // unless the DEBUG constant is defined


    using System.Diagnostics;
    class Class1 
    {
       [Conditional("DEBUG")]
       public static void ConditionalMethod() {
          Console.WriteLine("Executed Class1.ConditionalMethod");
       }
    }

Summary:

I would use #ifdef in C++ but with C#/VB I would use Conditional attribute. This way you hide the method definition without having to hide the pieces of code that call it. The calling code is still compiled and validated by the compiler, the method is not called at runtime though. You may want to use #if to avoid dependencies because with Conditional attribute your code is still compiled.

You are apparently using Django.

You are probably better off just using models.IntegerField() instead of models.TextField(). Not only will it do the check for you, but it will give you the error message translated in several langs, and it will cast the value from it's type in the database to the type in your Python code transparently.

That is because you are not fully qualifying your cells object. Try this

    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents

Notice the DOT before Cells?

If you dont need a feedback about the requested data and also dont need any interactivity between the opener and the popup, you can post a hidden form into the popup:

Example:

<form method="post" target="popup" id="formID" style="display:none" action="https://example.com/barcode/generate" >
  <input type="hidden" name="packing_slip" value="35592" />
  <input type="hidden" name="reference" value="0018439" />
  <input type="hidden" name="total_boxes" value="1" />
</form>
<script type="text/javascript">
window.open('about:blank','popup','width=300,height=200')
document.getElementById('formID').submit();
</script>

Otherwise you could use jsonp. But this works only, if you have access to the other Server, because you have to modify the response.

You can use tf.pack (tf.stack in TensorFlow 1.0.0) method for this purpose. Here is how to pack a random image of type numpy.ndarray into a Tensor:

import numpy as np
import tensorflow as tf
random_image = np.random.randint(0,256, (300,400,3))
random_image_tensor = tf.pack(random_image)
tf.InteractiveSession()
evaluated_tensor = random_image_tensor.eval()

UPDATE: to convert a Python object to a Tensor you can use tf.convert_to_tensor function.

You only need to check if response is ok coz the call not returning anything.

var json = {
    json: JSON.stringify({
        a: 1,
        b: 2
    }),
    delay: 3
};

fetch('/echo/json/', {
    method: 'post',
    headers: {
        'Accept': 'application/json, text/plain, */*',
        'Content-Type': 'application/json'
    },
    body: 'json=' + encodeURIComponent(JSON.stringify(json.json)) + '&delay=' + json.delay
})
.then((response) => {if(response.ok){alert("the call works ok")}})
.catch (function (error) {
    console.log('Request failed', error);
});    

Same Problem I had... I was writing all the script in a seperate file and was adding it through tag into the end of the HTML file after body tag. After moving the the tag inside the body tag it works fine. before :

after :

<script>require('../script/viewLog.js')</script>

It's about Shebang

This will tell which interpreter to wake up to run the code written in file.

Set Label's AutoSize property to False, TextAlign property to MiddleCenter and Dock property to Fill.

In Python 3, / is float division

In Python 2, / is integer division (assuming int inputs)

In both 2 and 3, // is integer division

(To get float division in Python 2 requires either of the operands be a float, either as 20. or float(20))

It doesn't. There's a vague equivalent:

mycol VARCHAR(10) NOT NULL CHECK (mycol IN('Useful', 'Useless', 'Unknown'))

It's the first result on Google: http://docs.python.org/library/stdtypes.html#string-formatting

See also the new format() function: http://docs.python.org/library/stdtypes.html#str.format

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

See also:

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->
    </c:if>
</c:forEeach>

The script below is a generic solution that works for me. It is based on ideas pulled from this and other threads.

When a link with an href attribute beginning with "#" is clicked, it scrolls the page smoothly to the indicated div. Where only the "#" is present, it scrolls smoothly to the top of the page.

$('a[href^=#]').click(function(){
    event.preventDefault();
    var target = $(this).attr('href');
    if (target == '#')
      $('html, body').animate({scrollTop : 0}, 600);
    else
      $('html, body').animate({
        scrollTop: $(target).offset().top - 100
    }, 600);
});

For example, When the code above is present, clicking a link with the tag <a href="#"> scrolls to the top of the page at speed 600. Clicking a link with the tag <a href="#mydiv"> scrolls to 100px above <div id="mydiv"> at speed 600. Feel free to change these numbers.

I hope it helps!

I tried the solutions above and none worked for me out of the box.

However http://www.baeldung.com/httpclient-post-http-request. Line 6 POST Multipart Request worked within seconds

public void whenSendMultipartRequestUsingHttpClient_thenCorrect() 
  throws ClientProtocolException, IOException {
    CloseableHttpClient client = HttpClients.createDefault();
    HttpPost httpPost = new HttpPost("http://www.example.com");

    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.addTextBody("username", "John");
    builder.addTextBody("password", "pass");
    builder.addBinaryBody("file", new File("test.txt"),
      ContentType.APPLICATION_OCTET_STREAM, "file.ext");

    HttpEntity multipart = builder.build();
    httpPost.setEntity(multipart);

    CloseableHttpResponse response = client.execute(httpPost);
    client.close();
}

I was using nodemailer npm module. The below code solved the issue

     tls: {
     // do not fail on invalid certs
     rejectUnauthorized: false
     }

Worked on the same issue , finally done this is top for the question so just putting what i did.

Observation - 1 -The file was not actually XLS i renamed to txt and noticed HTML text in file.

2 - Renamed the file to html and tried reading pd.read_html, Failed.

3- Added as it was not there in txt file, removed style to ensure that table is displaying in browser from local, and WORKED.

Below is the code may help someone..

import pandas as pd
import os
import shutil
import html5lib
import requests
from bs4 import BeautifulSoup
import re
import time

shutil.copy('your.xls','file.html')
shutil.copy('file.html','file.txt')
time.sleep(2)

txt = open('file.txt','r').read()

# Modify the text to ensure the data display in html page, delete style

txt = str(txt).replace('<style> .text { mso-number-format:\@; } </script>','')

# Add head and body if it is not there in HTML text

txt_with_head = '<html><head></head><body>'+txt+'</body></html>'

# Save the file as HTML

html_file = open('output.html','w')
html_file.write(txt_with_head)

# Use beautiful soup to read

url = r"C:\Users\hitesh kumar\PycharmProjects\OEM ML\output.html"
page = open(url)
soup = BeautifulSoup(page.read(), features="lxml")
my_table = soup.find("table",attrs={'border': '1'})

frame = pd.read_html(str(my_table))[0]
print(frame.head())
frame.to_excel('testoutput.xlsx',sheet_name='sheet1', index=False)

You can trick an interpreter with this ugly oneliner if None: var = None It do nothing else but adding a variable var to local variable dictionary, not initializing it. Interpreter will throw the UnboundLocalError exception if you try to use this variable in a function afterwards. This would works for very ancient python versions too. Not simple, nor beautiful, but don't expect much from python.

Maybe one of the easiest solutions would be to use the x descriptor of the srcset attribute as such:

<!-- Original image -->
<img src="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png" />

<!-- With a 80% size reduction (1/0.8=1.25) -->
<img srcset="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png 1.25x" />

<!-- With a 50% size reduction (1/0.5=2) -->
<img srcset="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png 2x" />

Currently supported by all browsers except IE. (caniuse)

MDN documentation

In all honesty I am only a little familiar with code safety, so this may be hack-ish. But for me this is the most versatile way to do it:

package com.my_objects.ip;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class MyIpByHost 
{
  public static void main(String a[])
  {
   try 
    {
      InetAddress host = InetAddress.getByName("nameOfDevice or webAddress");
      System.out.println(host.getHostAddress());
    } 
   catch (UnknownHostException e) 
    {
      e.printStackTrace();
    }
} }

In loop with .map work like this:

{
    dataForm.map(({ id, placeholder, type }) => {
        return <Input
            value={this.state.type}
            onChangeText={(text) => this.setState({ [type]: text })}
            placeholder={placeholder}
            key={id} />
    })
}

Note the [] in type parameter. Hope this helps :)

VSCode 1.42 (January 2020) introduces:

Panel on the left/right

The panel can now be moved to the left side of the editor with the setting:

"workbench.panel.defaultLocation": "left"

This removes the command View: Toggle Panel Position (workbench.action.togglePanelPosition) in favor of the following new commands:

• View: Move Panel Left (workbench.action.positionPanelLeft)
• View: Move Panel Right (workbench.action.positionPanelRight)
• View: Move Panel To Bottom (workbench.action.positionPanelBottom)

You can use css or js for hiding a div. In else statement you can write it as:

else{
?>
<style type="text/css">#divId{
display:none;
}</style>
<?php
}

Or in jQuery

else{
?>
<script type="text/javascript">$('#divId').hide()</script>
<?php
}

Or in javascript

else{
?>
<script type="text/javascript">document.getElementById('divId').style.display = 'none';</script>
<?php
}

If you want to display single value access from database into textbox, please refer to the code below:

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
TextBox1.Text=cmd.ExecuteScalar();
Con.Close();

or

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
SqlDataReader dr=new SqlDataReadr();
dr=cmd.Executereader();
if(dr.read())
{
    TextBox1.Text=dr.GetValue(0).Tostring();
}
Con.Close();

Wrap the multiple statements in a BEGIN END block to make them one statement and add a slash after the END; clause.

BEGIN
  insert into books
  (id, title, author)
  values
  (books_seq.nextval, 'The Bite in the Apple', 'Chrisann Brennan');

  insert into books
  (id, title, author)
  values
  (books_seq.nextval, 'The Restaurant at the End of the Universe', 'Douglas Adams');
END;
/

That way, it is just ctrl-a then ctrl-enter and it goes.

I think your best bet would be to leverage an existing library that does that very thing:

http://imakewebthings.com/waypoints/

You can add listeners to your elements that will fire off when your element hits the top of the viewport:

$('#scroll-to').waypoint(function() {
 alert('you have scrolled to the h1!');
});

For an amazing demo of it in use:

Using C++ in MS Visual Studio 2015 (14), I use:

#include <chrono>

string NowToString()
{
  chrono::system_clock::time_point p = chrono::system_clock::now();
  time_t t = chrono::system_clock::to_time_t(p);
  char str[26];
  ctime_s(str, sizeof str, &t);
  return str;
}

In ASP.NET Web API 2, you can wrap any ResponseMessage in a ResponseMessageResult:

public IHttpActionResult Get()
{
   HttpResponseMessage responseMessage = ...
   return new ResponseMessageResult(responseMessage);
}

In some cases this may be the simplest way to get the desired result, although generally it might be preferable to use the various results in System.Web.Http.Results.

32-bit Java is limited to approximately 1.4 to 1.6 GB.

Oracle 32 bit heap FAQ

Quote

The maximum theoretical heap limit for the 32-bit JVM is 4G. Due to various additional constraints such as available swap, kernel address space usage, memory fragmentation, and VM overhead, in practice the limit can be much lower. On most modern 32-bit Windows systems the maximum heap size will range from 1.4G to 1.6G. On 32-bit Solaris kernels the address space is limited to 2G. On 64-bit operating systems running the 32-bit VM, the max heap size can be higher, approaching 4G on many Solaris systems.

Now that we have LINQ, you can create an array with your two values (DateTimes, TimeSpans, whatever) and then use the .Max() extension method.

var values = new[] { Date1, Date2 }; 
var max = values.Max(); 

It reads nice, it's as efficient as Max can be, and it's reusable for more than 2 values of comparison.

The whole problem below worrying about .Kind is a big deal... but I avoid that by never working in local times, ever. If I have something important regarding times, I always work in UTC, even if it means more work to get there.

This would replicate exactly perl's chomp (minus behavior on arrays) for "\n" line terminator:

def chomp(x):
    if x.endswith("\r\n"): return x[:-2]
    if x.endswith("\n") or x.endswith("\r"): return x[:-1]
    return x

(Note: it does not modify string 'in place'; it does not strip extra trailing whitespace; takes \r\n in account)

ipdb is like pdb, with the awesomeness of ipython.

It is privacy concern. It is recommended to disallow users to backup an app if it contains sensitive data. Having access to backup files (i.e. when android:allowBackup="true"), it is possible to modify/read the content of an app even on a non-rooted device.

Solution - use android:allowBackup="false" in the manifest file.

You can read this post to have more information: Hacking Android Apps Using Backup Techniques

in my case, my localhost was http and my deployed version was https, so i used this script to add http-equiv meta tag only for https:

if (window.location.protocol.indexOf('https') == 0){
  var el = document.createElement('meta')
  el.setAttribute('http-equiv', 'Content-Security-Policy')
  el.setAttribute('content', 'upgrade-insecure-requests')
  document.head.append(el)

Here is an example of drawing a table using raphael.js. We can draw tables directly to the canvas of the browser using Raphael.js Raphael.js is a javascript library designed specifically for artists and graphic designers.

<!DOCTYPE html>
<html>

    <head>
    </head>
    <body>
        <div id='panel'></div>
    </body>
    <script src="http://cdnjs.cloudflare.com/ajax/libs/raphael/2.1.0/raphael-min.js"> </script>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

<script>    
paper = new Raphael(0,0,500,500);// width:500px, height:500px

var x = 100;
var y = 50;
var height = 50
var width = 100;

WriteTableRow(x,y,width*2,height,paper,"TOP Title");// draw a table header as merged cell
y= y+height;
WriteTableRow(x,y,width,height,paper,"Score,Player");// draw table header as individual cells
y= y+height;
for (i=1;i<=4;i++)
{
var k;
k = Math.floor(Math.random() * (10 + 1 - 5) + 5);//prepare table contents as random data
WriteTableRow(x,y,width,height,paper,i+","+ k + "");// draw a row
y= y+height;
}


function WriteTableRow(x,y,width,height,paper,TDdata)
{ // width:cell width, height:cell height, paper: canvas, TDdata: texts for a row. Separated each cell content with a comma.

    var TD = TDdata.split(",");
    for (j=0;j<TD.length;j++)
    {
        var rect = paper.rect(x,y,width,height).attr({"fill":"white","stroke":"red"});// draw outline
        paper.text(x+width/2, y+height/2, TD[j]) ;// draw cell text
        x = x + width;
    }
}

Use sys.getsizeof to get the size of an object, in bytes.

>>> from sys import getsizeof
>>> a = 42
>>> getsizeof(a)
12
>>> a = 2**1000
>>> getsizeof(a)
146
>>>

Note that the size and layout of an object is purely implementation-specific. CPython, for example, may use totally different internal data structures than IronPython. So the size of an object may vary from implementation to implementation.

A few things have changed since the top answers were added. They used to work out for me, but not quite anymore, so I have been hacking around for a bit and came up with the following solution for Ubuntu 16.04. For Ubuntu 14.04, see the comment at the bottom of the answer. Apologies if this doesn't work for shared hosting, but it seems like this is the goto answer for wkhtmltopdf installation instructions in general.

# Install dependencies
apt-get install libfontconfig \
    zlib1g \
    libfreetype6 \
    libxrender1 \
    libxext6 \
    libx11-6

# TEMPORARY FIX! SEE: https://github.com/wkhtmltopdf/wkhtmltopdf/issues/3001
apt-get install libssl1.0.0=1.0.2g-1ubuntu4.8
apt-get install libssl-dev=1.0.2g-1ubuntu4.8

# Download, extract and move binary in place
curl -L -o wkhtmltopdf.tar.xz https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar -xf wkhtmltopdf.tar.xz
mv wkhtmltox/bin/wkhtmltopdf /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf

Test it out:

wkhtmltopdf http://www.google.com google.pdf

You should now have a file named google.pdf in the current working directory.

This approach downloads the binary from the website, meaning that you can use the latest version instead of relying on package managers to be updated.

Note that as of today, my solution includes a temporary fix to this bug. I realize that the solution is really not great, but hopefully it can be removed soon. Be sure to check the status of the linked GitHub issue to see if the fix is still necessary when you read this answer!

For Ubuntu 14.04, you will need to downgrade to a different version of libssl. You can find the versions here. Anyways, be sure to consider the implications of downgrading libssl before doing so on any production server.

I hope this helps someone!

Kbrose's guidance on finding which logger was generating log messages was immensely useful. For my Django project, I had to sort through 120 different loggers until I found that it was the elasticsearch Python library that was causing issues for me. As per the guidance in most of the questions, I disabled it by adding this to my loggers:

      ...
      'elasticsearch': {
          'handlers': ['console'],
          'level': logging.WARNING,
      },     
      ...

Posting here in case someone else is seeing the unhelpful log messages come through whenever they run an Elasticsearch query.

use the following file prefix, this will add to your perl script eTRUE and eFALSE, it will actually be REAL(!) true and false (just like java)

#!/usr/bin/perl
use strict;
use warnings;

use constant { #real true false, compatible with encode_json decode_json for later (we don't want field:false... will be field:0...)
                eTRUE  =>  bless( do{\(my $o = 1)}, 'JSON::PP::Boolean' ),
                eFALSE =>  bless( do{\(my $o = 0)}, 'JSON::PP::Boolean' )
             };

There are, actually, few reasons why you should use that.

My reason is that working with JSON, I've got 0 and 1 as values to keys, but this hack will make sure correct values are kept along your script.

@Resource is often used by high-level objects, defined via JNDI. @Autowired or @Inject will be used by more common beans.

As far as I know, it's not a specification, nor even a convention. It's more the logical way standard code will use these annotations.

SUPER KEY:

Attribute or set of attributes used to uniquely identify tuples in the database.

CANDIDATE KEY:

1. Minimal super key is the candidate key
2. Can be one or many
3. Potential primary keys
4. not null
5. attribute or set of attributes to uniquely identify records in DB

PRIMARY KEY:

1. one of the candidate key which is used to identify records in DB uniquely

2. not null

I do not know if your still looking for the answer to this problem but today I happened the same problem and solved it. You need to specify in the HTML code,

**<Div class = "navbar"**>
         div class = "container">
               <Div class = "navbar-header">

or

**<Div class = "navbar navbar-default">**
        div class = "container">
               <Div class = "navbar-header">

You got that place in your CSS

.navbar-default-toggle .navbar .icon-bar {
  background-color: # 0000ff;
}

and what I did was add above

.navbar .navbar-toggle .icon-bar {
  background-color: # ff0000;
}

Because my html code is

**<Div class = "navbar">**
         div class = "container">
               <Div class = "navbar-header">

and if you associate a file less / css

search this section and also here placed the color you want to change, otherwise it will self-correct the css file to the state it was before

// Toggle Navbar
@ Navbar-default-toggle-hover-bg: #ddd;
**@ Navbar-default-toggle-icon-bar-bg: # 888;**
@ Navbar-default-toggle-border-color: #ddd;

if your html code is like mine and is not navbar-default, add it as you did with the css.

// Toggle Navbar
@ Navbar-default-toggle-hover-bg: #ddd;
**@ Navbar-toggle-icon-bar-bg : #888;**
@ Navbar-default-toggle-icon-bar-bg: # 888;
@ Navbar-default-toggle-border-color: #ddd;

good luck

The best way to deal with this (if a declaration file is not available on DefinitelyTyped) is to write declarations only for the things you use rather than the entire library. This reduces the work a lot - and additionally the compiler is there to help out by complaining about missing methods.

I have tested the suggested solutions, they should all work:

select * from dual where (105 = to_number('105'))

=> delivers one dummy row

select * from dual where (10 = to_number('105'))

=> empty result

select * from dual where ('105' = to_char(105))

=> delivers one dummy row

select * from dual where ('105' = to_char(10))

=> empty result

It seems that Go have special form of switch dedicate to this (it is called type switch):

func (e *Easy)SetOption(option Option, param interface{}) {

    switch v := param.(type) { 
    default:
        fmt.Printf("unexpected type %T", v)
    case uint64:
        e.code = Code(C.curl_wrapper_easy_setopt_long(e.curl, C.CURLoption(option), C.long(v)))
    case string:
        e.code = Code(C.curl_wrapper_easy_setopt_str(e.curl, C.CURLoption(option), C.CString(v)))
    } 
}

Or try:

$("#datetimepicker").data().date;

Alt simplification of https://stackoverflow.com/users/1969435/gx1sptdtda above:

cond <-c(1,2,3)
rating <-c(100,200,300)
df <- data.frame(cond, rating)
df
  cond rating
1    1    100
2    2    200
3    3    300

Create the reference of image....

UIImage *rainyImage = [UIImage imageNamed:@"rainy.jpg"];

displaying image in image view... imagedisplay is reference of imageview:

imagedisplay.image = rainyImage;

convert it into NSData by passing UIImage reference and provide compression quality in float values:

NSData *imgData = UIImageJPEGRepresentation(rainyImage, 0.9);

Keep the first intent filter with keys MAIN and LAUNCHER and add another as ANY_NAME and DEFAULT.

Your LAUNCHER will be activity A and DEFAULT will be your activity B.

In my case I use a template component in Blazor.

 <BTable ID="Table1" TotalRows="MyList.Count()">

The problem is calling a method (Count) in the component header. To resolve the problem I changed it like this :

int total = MyList.Count();

and later :

<BTable ID="Table1" TotalRows="total">

I usually use the idiom

Object value = map.get(key);
if (value == null) {
    value = createValue(key);
    map.put(key, value);
}

This means you only hit the map twice if the key is missing

To fully overload it you also need to implement the __setitem__and __delitem__ methods.

edit

I almost forgot... if you want to completely emulate a list, you also need __getslice__, __setslice__ and __delslice__.

There are all documented in http://docs.python.org/reference/datamodel.html

You can set the desired time in milliseconds in the Toast.makeText(); method like this:

//40 seconds
long mToastLength = 40*1000 
//this toast will be displayed for 40 seconds.
Toast.makeText(this, "Hello!!!!!", mToastLength).show(); 

That .toggle() method was removed from jQuery in version 1.9. You can do this instead:

$(document).ready(function() {
    $('#showmenu').click(function() {
            $('.menu').slideToggle("fast");
    });
});

Demo: http://jsfiddle.net/APA2S/1/

...but as with the code in your question that would slide up or down. To slide left or right you can do the following:

$(document).ready(function() {
    $('#showmenu').click(function() {
         $('.menu').toggle("slide");
    });
});

Demo: http://jsfiddle.net/APA2S/2/

Noting that this requires jQuery-UI's slide effect, but you added that tag to your question so I assume that is OK.

using namespace std;


// c++03
string s = "(555) 555-5555";
s.erase(remove_if(s.begin(), s.end(), not1(ptr_fun(::isdigit))), s.end());

// c++11
s.erase(remove_if(s.begin(), s.end(), ptr_fun(::ispunct)), s.end());

Note: It's posible you need write ptr_fun<int, int> rather than simple ptr_fun

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.

For example, suppose the browser makes a request with the following headers:

Origin: http://yourdomain.com
Access-Control-Request-Method: POST
Access-Control-Request-Headers: X-Custom-Header

Your server should then respond with the following headers:

Access-Control-Allow-Origin: http://yourdomain.com
Access-Control-Allow-Methods: GET, POST
Access-Control-Allow-Headers: X-Custom-Header

Pay special attention to the Access-Control-Allow-Headers response header. The value of this header should be the same headers in the Access-Control-Request-Headers request header, and it can not be '*'.

Once you send this response to the preflight request, the browser will make the actual request. You can learn more about CORS here: http://www.html5rocks.com/en/tutorials/cors/

MySQL 5.7: Using GRANT to create users. Instead, use CREATE USER. Following this practice makes the NO_AUTO_CREATE_USER SQL mode immaterial for GRANT statements, so it too is deprecated. MySQL 8.0.11: Using GRANT to create users. Instead, use CREATE USER. Following this practice makes the NO_AUTO_CREATE_USER SQL mode immaterial for GRANT statements, so it too is removed.

Taken from here

So, your sql_mode can be like this:

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

Or if you're using Docker you can add next command to docker-compose.yml

  mysql:
    image: mysql:8.0.13
    command: --sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
    ports:
      - 13306:${MYSQL_PORT}

Found the answer to this from one of the MySQL forums. We’ll need to use a procedure to delete the user.

User here is “test” and “databaseName” the database name.

SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='ANSI';
USE databaseName ;
DROP PROCEDURE IF EXISTS databaseName.drop_user_if_exists ;
DELIMITER $$
CREATE PROCEDURE databaseName.drop_user_if_exists()
BEGIN
  DECLARE foo BIGINT DEFAULT 0 ;
  SELECT COUNT(*)
  INTO foo
    FROM mysql.user
      WHERE User = 'test' and  Host = 'localhost';
   IF foo > 0 THEN
         DROP USER 'test'@'localhost' ;
  END IF;
END ;$$
DELIMITER ;
CALL databaseName.drop_user_if_exists() ;
DROP PROCEDURE IF EXISTS databaseName.drop_users_if_exists ;
SET SQL_MODE=@OLD_SQL_MODE ;

CREATE USER 'test'@'localhost' IDENTIFIED BY 'a';
GRANT ALL PRIVILEGES ON databaseName.* TO 'test'@'localhost'
WITH GRANT OPTION

Here's a good one:

Set line-height equal to whatever the height is; works like a charm!

E.g:

li {
    height: 30px;
    line-height: 30px;
}

The method System.Web.UI.Page.RegisterClientScriptBlock has been deprecated for some time (along with the other Page.Register* methods), ever since .NET 2.0 as shown by MSDN.

Instead use the .NET 2.0 Page.ClientScript.Register* methods. - (The ClientScript property expresses an instance of the ClientScriptManager class )

Guessing the problem

If you are saying your JavaScript alert box occurs before the page's content is visibly rendered, and therefore the page remains white (or still unrendered) when the alert box is dismissed by the user, then try using the Page.ClientScript.RegisterStartupScript(..) method instead because it runs the given client-side code when the page finishes loading - and its arguments are similar to what you're using already.

Also check for general JavaScript errors in the page - this is often seen by an error icon in the browser's status bar. Sometimes a JavaScript error will hold up or disturb unrelated elements on the page.

Check out fontsquirrel. They have a web font generator, which will also spit out a suitable stylesheet for your font (look for "@font-face kit"). This stylesheet can be included in your own, or you can use it as a template.

Based on the answers provided, I decided to make a quick plugin to do this:

(function($){
    $.fn.moveTo = function(selector){
        return this.each(function(){
            var cl = $(this).clone();
            $(cl).appendTo(selector);
            $(this).remove();
        });
    };
})(jQuery);

Usage:

$('#nodeToMove').moveTo('#newParent');

Node.js does not run in a browser, therefore you will not have a document object available. Actually, you will not even have a DOM tree at all. If you are a bit confused at this point, I encourage you to read more about it before going further.

There are a few methods you can choose from to do what you want.

Method 1: Serving the file directly via HTTP

Because you wrote about opening the file in the browser, why don't you use a framework that will serve the file directly as an HTTP service, instead of having a two-step process? This way, your code will be more dynamic and easily maintainable (not mentioning your HTML always up-to-date).

There are plenty frameworks out there for that :

• Http (Node native API)
• Connect
• koa
• Express (using Connect)
• Sails (build on Express)
• Geddy
• CompoundJS
• etc.

The most basic way you could do what you want is this :

var http = require('http');

http.createServer(function (req, res) {
  var html = buildHtml(req);

  res.writeHead(200, {
    'Content-Type': 'text/html',
    'Content-Length': html.length,
    'Expires': new Date().toUTCString()
  });
  res.end(html);
}).listen(8080);

function buildHtml(req) {
  var header = '';
  var body = '';

  // concatenate header string
  // concatenate body string

  return '<!DOCTYPE html>'
       + '<html><head>' + header + '</head><body>' + body + '</body></html>';
};

And access this HTML with http://localhost:8080 from your browser.

(Edit: you could also serve them with a small HTTP server.)

Method 2: Generating the file only

If what you are trying to do is simply generating some HTML files, then go simple. To perform IO access on the file system, Node has an API for that, documented here.

var fs = require('fs');

var fileName = 'path/to/file';
var stream = fs.createWriteStream(fileName);

stream.once('open', function(fd) {
  var html = buildHtml();

  stream.end(html);
});

Note: The buildHtml function is exactly the same as in Method 1.

Method 3: Dumping the file directly into stdout

This is the most basic Node.js implementation and requires the invoking application to handle the output itself. To output something in Node (ie. to stdout), the best way is to use console.log(message) where message is any string, or object, etc.

var html = buildHtml();

console.log(html);

Note: The buildHtml function is exactly the same as in Method 1 (again)

If your script is called html-generator.js (for example), in Linux/Unix based system, simply do

$ node html-generator.js > path/to/file

Conclusion

Because Node is a modular system, you can even put the buildHtml function inside it's own module and simply write adapters to handle the HTML however you like. Something like

var htmlBuilder = require('path/to/html-builder-module');

var html = htmlBuilder(options);
...

You have to think "server-side" and not "client-side" when writing JavaScript for Node.js; you are not in a browser and/or limited to a sandbox, other than the V8 engine.

Extra reading, learn about npm. Hope this helps.

This is not the most fastest method around the block, but is fairly simple to understand if you don't wanna involve yourself in HashMaps and also want to avoid using 2 for loops for complexity issues....

    int mode(int n, int[] ar) {
    int personalMax=1,totalMax=0,maxNum=0;

    for(int i=0;i<n-1;i++)
    {

        if(ar[i]==ar[i+1])
        {
            personalMax++;

            if(totalMax<personalMax)
            {
                totalMax=personalMax;
                maxNum=ar[i];
            }
        }    
        else
        {
            personalMax=1;
        }
    }
    return maxNum;
}

1. Open Git Bash
2. Type ps -ef | grep java
3. Find the pid of running jdk
4. kill -9 [pid]

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

Pure numpy

numpy.loadtxt(open("test.csv", "rb"), delimiter=",", skiprows=1)

Check out the loadtxt documentation.

You can also use python's csv module:

import csv
import numpy
reader = csv.reader(open("test.csv", "rb"), delimiter=",")
x = list(reader)
result = numpy.array(x).astype("float")

You will have to convert it to your favorite numeric type. I guess you can write the whole thing in one line:

result = numpy.array(list(csv.reader(open("test.csv", "rb"), delimiter=","))).astype("float")

Added Hint:

You could also use pandas.io.parsers.read_csv and get the associated numpy array which can be faster.

UPDATE

A more direct jQuery method to the option selected would be:

var selected_option = $('#mySelectBox option:selected');

Answering the question .is(':selected') is what you are looking for:

$('#mySelectBox option').each(function() {
    if($(this).is(':selected')) ...

The non jQuery (arguably best practice) way to do it would be:

$('#mySelectBox option').each(function() {
    if(this.selected) ...

Although, if you are just looking for the selected value try:

$('#mySelectBox').val()

If you are looking for the selected value's text do:

$('#mySelectBox option').filter(':selected').text();

Check out: http://api.jquery.com/selected-selector/

Next time look for duplicate SO questions:

Get current selected option or Set selected option or How to get $(this) selected option in jQuery? or option[selected=true] doesn't work

From the two linksResolved Successfully and Naming Convention, I easily solved this same problem which I faced. i.e., for the foreign key name, give as fk_colName_TableName. This naming convention is non-ambiguous and also makes every ForeignKey in your DB Model unique and you will never get this error.

Error 1022: Can't write; duplicate key in table

The closest option available is

[\u\l]+

which matches a sequence of uppercase and lowercase letters. However, it is not supported by all editors/languages, so it is probably safer to use

[a-zA-Z]+

as other users suggest

Sending the same cookie value with ; expires appended will not destroy the cookie.

Invalidate the cookie by setting an empty value and include an expires field as well:

Set-Cookie: token=deleted; path=/; expires=Thu, 01 Jan 1970 00:00:00 GMT

Note that you cannot force all browsers to delete a cookie. The client can configure the browser in such a way that the cookie persists, even if it's expired. Setting the value as described above would solve this problem.

File -> Invalidate Caches/Restart and choose invalidate and Restart button in the dialog appeared.

The combination that worked for me was:

1. Copy the dSYM file into the directory where the crash report was
2. Unzip the ipa file containing the app ('unzip MyApp.ipa')
3. Copy the application binary from the resulting exploded payload into the same folder as the crash report and symbol file (Something like "MyApp.app/MyApp")
4. Import or Re-symbolicate the crash report from within Xcode's organizer

Using atos I wasn't able to resolve the correct symbol information with the addresses and offsets that were in the crash report. When I did this, I see something more meaningful, and it seems to be a legitimate stack trace.

Here's a version that works recursively (using *) on an arbitrary number of objects:

echo '{"A": {"a": 1}}' '{"A": {"b": 2}}' '{"B": 3}' |\
  jq --slurp 'reduce .[] as $item ({}; . * $item)'

{
  "A": {
    "a": 1,
    "b": 2
  },
  "B": 3
}

Not all browsers handle the keypress event well, so use either the key up or the key down event, like this:

$(document).keydown(function (e) {
    if (e.keyCode == 16) {
        alert(e.which + " or Shift was pressed");
    }
});

This is a function we are using in our application and it is working fine.

delete cookie: No argument method

function clearListCookies()
{   
    var cookies = document.cookie.split(";");
    for (var i = 0; i < cookies.length; i++)
    {   
        var spcook =  cookies[i].split("=");
        deleteCookie(spcook[0]);
    }
    function deleteCookie(cookiename)
    {
        var d = new Date();
        d.setDate(d.getDate() - 1);
        var expires = ";expires="+d;
        var name=cookiename;
        //alert(name);
        var value="";
        document.cookie = name + "=" + value + expires + "; path=/acc/html";                    
    }
    window.location = ""; // TO REFRESH THE PAGE
}

Edit: This will delete the cookie by setting it to yesterday's date.

Use [[:blank:]] to match any kind of horizontal white_space characters.

If key isn't an int or float but a string, you need to convert it to an int first by doing

key = int(key)

or to a float by doing

key = float(key)

Otherwise, what you have in your question should work, but

if (key < 1) or (key > 34):

or

if not (1 <= key <= 34):

would be a bit clearer.

For retrieving the screen resolution, you're going to want to use the System.Windows.Forms.Screen class. The Screen.AllScreens property can be used to access a collection of all of the displays on the system, or you can use the Screen.PrimaryScreen property to access the primary display.

The Screen class has a property called Bounds, which you can use to determine the resolution of the current instance of the class. For example, to determine the resolution of the current screen:

Rectangle resolution = Screen.PrimaryScreen.Bounds;

For changing the resolution, things get a little more complicated. This article (or this one) provides a detailed implementation and explanation. Hope this helps.

I think it will be perfect solution:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <!-- Other views -->
    <Space
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <!-- Target view below -->
    <View
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

</LinearLayout>

Nice explanation and example above. I found this (JSON.stringify() array bizarreness with Prototype.js) to complete the answer. Some sites implements its own toJSON with JSONFilters, so delete it.

if(window.Prototype) {
    delete Object.prototype.toJSON;
    delete Array.prototype.toJSON;
    delete Hash.prototype.toJSON;
    delete String.prototype.toJSON;
}

it works fine and the output of the test:

console.log(json);

Result:

"{"a":"test","b":["item","item2","item3"]}"

You have a concrete example of a Student and a MessageBoard. The Student registers by adding itself to the list of Observers that want to be notified when a new Message is posted to the MessageBoard. When a Message is added to the MessageBoard, it iterates over its list of Observers and notifies them that the event occurred.

Think Twitter. When you say you want to follow someone, Twitter adds you to their follower list. When they sent a new tweet in, you see it in your input. In that case, your Twitter account is the Observer and the person you're following is the Observable.

The analogy might not be perfect, because Twitter is more likely to be a Mediator. But it illustrates the point.

I believe the reason why the first set of properties will not work is because there is no auto value for display, so that property should be ignored. In that case, inline-table will still take effect, and as width do not apply to inline elements, that set of properties will not do anything.

The second set of properties will simply hide the table, as that's what display: none is for.

Try resetting it to table instead:

table.other {
    width: auto;
    min-width: 0;
    display: table;
}

Edit: min-width defaults to 0, not auto

Here's how I had to use it in my curl script for couchDB. It really helped out a lot. Thanks!

bin/curl -X PUT "db_domain_name_:5984/_config/vhosts/$1.couchdb" -d '"/'"$1"'/"' --user "admin:*****"

I am using CDN for my project and as part of fallback handling, i was using below code,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript">
                if ((typeof jQuery == 'undefined')) {
                    document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
                }
</script>

Just to verify, i removed CDN reference and execute the code. Its broken and it's never entered into if loop as typeof jQuery is coming as function instead of undefined .

This is because of cached older version of jquery 1.6.1 which return function and break my code because i am using jquery 1.9.1. As i need exact version of jquery, i modified code as below,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript">
            if ((typeof jQuery == 'undefined') || (jQuery.fn.jquery != "1.9.1")) {
                document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
            }
</script>

You can try to do json.loads(), which will throw a ValueError if the string you pass can't be decoded as JSON.

In general, the "Pythonic" philosophy for this kind of situation is called EAFP, for Easier to Ask for Forgiveness than Permission.

Based on Wikipedia's articles.

Greedy Approach

A greedy algorithm is an algorithm that follows the problem solving heuristic of making the locally optimal choice at each stage with the hope of finding a global optimum. In many problems, a greedy strategy does not in general produce an optimal solution, but nonetheless a greedy heuristic may yield locally optimal solutions that approximate a global optimal solution in a reasonable time.

We can make whatever choice seems best at the moment and then solve the subproblems that arise later. The choice made by a greedy algorithm may depend on choices made so far but not on future choices or all the solutions to the subproblem. It iteratively makes one greedy choice after another, reducing each given problem into a smaller one.

Dynamic programming

The idea behind dynamic programming is quite simple. In general, to solve a given problem, we need to solve different parts of the problem (subproblems), then combine the solutions of the subproblems to reach an overall solution. Often when using a more naive method, many of the subproblems are generated and solved many times. The dynamic programming approach seeks to solve each subproblem only once, thus reducing the number of computations: once the solution to a given subproblem has been computed, it is stored or "memo-ized": the next time the same solution is needed, it is simply looked up. This approach is especially useful when the number of repeating subproblems grows exponentially as a function of the size of the input.

Difference

Greedy choice property

We can make whatever choice seems best at the moment and then solve the subproblems that arise later. The choice made by a greedy algorithm may depend on choices made so far but not on future choices or all the solutions to the subproblem. It iteratively makes one greedy choice after another, reducing each given problem into a smaller one. In other words, a greedy algorithm never reconsiders its choices.

This is the main difference from dynamic programming, which is exhaustive and is guaranteed to find the solution. After every stage, dynamic programming makes decisions based on all the decisions made in the previous stage, and may reconsider the previous stage's algorithmic path to solution.

For example, let's say that you have to get from point A to point B as fast as possible, in a given city, during rush hour. A dynamic programming algorithm will look into the entire traffic report, looking into all possible combinations of roads you might take, and will only then tell you which way is the fastest. Of course, you might have to wait for a while until the algorithm finishes, and only then can you start driving. The path you will take will be the fastest one (assuming that nothing changed in the external environment).

On the other hand, a greedy algorithm will start you driving immediately and will pick the road that looks the fastest at every intersection. As you can imagine, this strategy might not lead to the fastest arrival time, since you might take some "easy" streets and then find yourself hopelessly stuck in a traffic jam.

Some other details...

In mathematical optimization, greedy algorithms solve combinatorial problems having the properties of matroids.

Dynamic programming is applicable to problems exhibiting the properties of overlapping subproblems and optimal substructure.

You can simply copy it to an array:

int[] arr = new int[list.size()];
for(int i = 0; i < list.size(); i++) {
    arr[i] = list.get(i);
}

Not too fancy; but, hey, it works...

If you just happen to have a Map with Integer keys you cannot change, you could write a custom EL function to convert a Long to Integer. This would allow you to do something like:

<c:out value="${map[myLib:longToInteger(1)]}"/>

There is a tech recipe available here that shows how to format it to MMDDYYYY, you should be able to adapt it for your needs.

echo on
@REM Seamonkey’s quick date batch (MMDDYYYY format)
@REM Setups %date variable
@REM First parses month, day, and year into mm , dd, yyyy formats and then combines to be MMDDYYYY
FOR /F "TOKENS=1* DELIMS= " %%A IN ('DATE/T') DO SET CDATE=%%B
FOR /F "TOKENS=1,2 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET mm=%%B
FOR /F "TOKENS=1,2 DELIMS=/ eol=/" %%A IN ('echo %CDATE%') DO SET dd=%%B
FOR /F "TOKENS=2,3 DELIMS=/ " %%A IN ('echo %CDATE%') DO SET yyyy=%%B
SET date=%mm%%dd%%yyyy%

echo %date%

EDIT: The reason did not work before was because of 'smartquotes' in the original text. I fixed them and the batch file will work if cut & pasted from this page.

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName to be the name of the file you wish to open.

Private Const TargetWBName As String = "myworkbook.xlsx"

'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
    WorkbookOpen = False
    On Error GoTo WorkBookNotOpen
    If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
        WorkbookOpen = True
        Exit Function
    End If
WorkBookNotOpen:
End Function

Private Sub Workbook_Open()
    'Check if our target workbook is open
    If WorkbookOpen(TargetWBName) = False Then
        'set calculation to manual
        Application.Calculation = xlCalculationManual
        Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
        DoEvents
        Me.Close False
    End If
End Sub

Set the constant 'TargetWBName' to be the name of the workbook that you wish to open. This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself. *NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True after Me.Close

Here is how I do it and works both for create and edit:

//How to do it with enums
<div class="editor-field">
   @Html.RadioButtonFor(x => x.gender, (int)Gender.Male) Male
   @Html.RadioButtonFor(x => x.gender, (int)Gender.Female) Female
</div>

//And with Booleans
<div class="editor-field">
   @Html.RadioButtonFor(x => x.IsMale, true) Male
   @Html.RadioButtonFor(x => x.IsMale, false) Female
</div>

the provided values (true and false) are the values that the engine will render as the values for the html element i.e.:

<input id="IsMale" type="radio" name="IsMale" value="True">
<input id="IsMale" type="radio" name="IsMale" value="False">

And the checked property is dependent on the Model.IsMale value.

Razor engine seems to internally match the set radio button value to your model value, if a proper from and to string convert exists for it. So there is no need to add it as an html attribute in the helper method.

WORKAROUND:

The possible workaround is modify your project's platform from 'Any CPU' to 'X86' (in Project's Properties, Build/Platform's Target)

ROOTCAUSE

The VSS Interop is a managed assembly using 32-bit Framework and the dll contains a 32-bit COM object. If you run this COM dll in 64 bit environment, you will get the error message.

A python class that acts like dict

By request - adding slots to a dict subclass.

Why add slots? A builtin dict instance doesn't have arbitrary attributes:

>>> d = dict()
>>> d.foo = 'bar'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'dict' object has no attribute 'foo'

If we create a subclass the way most are doing it here on this answer, we see we don't get the same behavior, because we'll have a __dict__ attribute, causing our dicts to take up to potentially twice the space:

my_dict(dict):
    """my subclass of dict""" 

md = my_dict()
md.foo = 'bar'

Since there's no error created by the above, the above class doesn't actually act, "like dict."

We can make it act like dict by giving it empty slots:

class my_dict(dict):
    __slots__ = ()

md = my_dict()

So now attempting to use arbitrary attributes will fail:

>>> md.foo = 'bar'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'my_dict' object has no attribute 'foo'

And this Python class acts more like a dict.

For more on how and why to use slots, see this Q&A: Usage of __slots__?

I solved the problem. I made mistake in setData(Uri) and setType(String).

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

That is correct now, my auto-update is working. Thanks for help. =)

Edit 20.7.2016:

After a long time, I had to use this way of updating again in another project. I encountered a number of problems with old solution. A lot of things have changed in that time, so I had to do this with a different approach. Here is the code:

    //get destination to update file and set Uri
    //TODO: First I wanted to store my update .apk file on internal storage for my app but apparently android does not allow you to open and install
    //aplication with existing package from there. So for me, alternative solution is Download directory in external storage. If there is better
    //solution, please inform us in comment
    String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
    String fileName = "AppName.apk";
    destination += fileName;
    final Uri uri = Uri.parse("file://" + destination);

    //Delete update file if exists
    File file = new File(destination);
    if (file.exists())
    //file.delete() - test this, I think sometimes it doesnt work
        file.delete();

    //get url of app on server
    String url = Main.this.getString(R.string.update_app_url);

    //set downloadmanager
    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
    request.setDescription(Main.this.getString(R.string.notification_description));
    request.setTitle(Main.this.getString(R.string.app_name));

    //set destination
    request.setDestinationUri(uri);

    // get download service and enqueue file
    final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
    final long downloadId = manager.enqueue(request);

    //set BroadcastReceiver to install app when .apk is downloaded
    BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            Intent install = new Intent(Intent.ACTION_VIEW);
            install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            install.setDataAndType(uri,
                    manager.getMimeTypeForDownloadedFile(downloadId));
            startActivity(install);

            unregisterReceiver(this);
            finish();
        }
    };
    //register receiver for when .apk download is compete
    registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

My observations based on a few tests has been that whichever name differs from the property name is one which takes effect:

For eg. consider a slight modification of your case:

@JsonProperty("fileName")
private String fileName;

@JsonProperty("fileName")
public String getFileName()
{
    return fileName;
}

@JsonProperty("fileName1")
public void setFileName(String fileName)
{
    this.fileName = fileName;
}

Both fileName field, and method getFileName, have the correct property name of fileName and setFileName has a different one fileName1, in this case Jackson will look for a fileName1 attribute in json at the point of deserialization and will create a attribute called fileName1 at the point of serialization.

Now, coming to your case, where all the three @JsonProperty differ from the default propertyname of fileName, it would just pick one of them as the attribute(FILENAME), and had any on of the three differed, it would have thrown an exception:

java.lang.IllegalStateException: Conflicting property name definitions

I just wrote a quick function to do this. I needed it to handle many forms so I made it so it will accept a string separated by ','.

//function to make sure that all of the required fields of a post are sent. Returns True for error and False for NO error  
//accepts a string that is then parsed by "," into an array. The array is then checked for empty values.
function errorPOSTEmpty($stringOfFields) {
        $error = false;
            if(!empty($stringOfFields)) {
                // Required field names
                $required = explode(',',$stringOfFields);
                // Loop over field names
                foreach($required as $field) {
                  // Make sure each one exists and is not empty
                  if (empty($_POST[$field])) {
                    $error = true;
                    // No need to continue loop if 1 is found.
                    break;
                  }
                }
            }
    return $error;
}

So you can enter this function in your code, and handle errors on a per page basis.

$postError = errorPOSTEmpty('login,password,confirm,name,phone,email');

if ($postError === true) {
  ...error code...
} else {
  ...vars set goto POSTing code...
}

try

raw_input('Enter your input:')  # If you use Python 2
input('Enter your input:')      # If you use Python 3

and if you want to have a numeric value just convert it:

try:
    mode=int(raw_input('Input:'))
except ValueError:
    print "Not a number"

Simple:

if(window.location.hash) {
  // Fragment exists
} else {
  // Fragment doesn't exist
}

For questions like this, it is always worth taking a look in the manual first. Date and time functions in the mySQL manual

CURDATE() returns the DATE part of the current time. Manual on CURDATE()

NOW() returns the date and time portions as a timestamp in various formats, depending on how it was requested. Manual on NOW().

Try this function ...

public static string GetTempFilePathWithExtension(string extension) {
  var path = Path.GetTempPath();
  var fileName = Guid.NewGuid().ToString() + extension;
  return Path.Combine(path, fileName);
}

It will return a full path with the extension of your choice.

Note, it's not guaranteed to produce a unique file name since someone else could have technically already created that file. However the chances of someone guessing the next guid produced by your app and creating it is very very low. It's pretty safe to assume this will be unique.

No, it is better practice to leave them out.

Without strip(), you can have empty keys and values:

apples<tab>round, fruity things
oranges<tab>round, fruity things
bananas<tab>

Without strip(), bananas is present in the dictionary but with an empty string as value. With strip(), this code will throw an exception because it strips the tab of the banana line.

Use a service to achieve this:

MyApp.app.service("xxxSvc", function () {

var _xxx = {};

return {
    getXxx: function () {
        return _xxx;
    },
    setXxx: function (value) {
        _xxx = value;
    }
};

});

Next, inject this service into both controllers.

In Controller1, you would need to set the shared xxx value with a call to the service: xxxSvc.setXxx(xxx)

Finally, in Controller2, add a $watch on this service's getXxx() function like so:

  $scope.$watch(function () { return xxxSvc.getXxx(); }, function (newValue, oldValue) {
        if (newValue != null) {
            //update Controller2's xxx value
            $scope.xxx= newValue;
        }
    }, true);

Merge byte arrays of multiple PDF files:

    public static byte[] MergePDFs(List<byte[]> pdfFiles)
    {  
        if (pdfFiles.Count > 1)
        {
            PdfReader finalPdf;
            Document pdfContainer;
            PdfWriter pdfCopy;
            MemoryStream msFinalPdf = new MemoryStream();

            finalPdf = new PdfReader(pdfFiles[0]);
            pdfContainer = new Document();
            pdfCopy = new PdfSmartCopy(pdfContainer, msFinalPdf);

            pdfContainer.Open();

            for (int k = 0; k < pdfFiles.Count; k++)
            {
                finalPdf = new PdfReader(pdfFiles[k]);
                for (int i = 1; i < finalPdf.NumberOfPages + 1; i++)
                {
                    ((PdfSmartCopy)pdfCopy).AddPage(pdfCopy.GetImportedPage(finalPdf, i));
                }
                pdfCopy.FreeReader(finalPdf);

            }
            finalPdf.Close();
            pdfCopy.Close();
            pdfContainer.Close();

            return msFinalPdf.ToArray();
        }
        else if (pdfFiles.Count == 1)
        {
            return pdfFiles[0];
        }
        return null;
    }

This is all that you had to do man, change his MyViewModel model to IList.

You can always add it exactly for your application

angular.isUndefinedOrNull = function(val) {
    return angular.isUndefined(val) || val === null 
}

The Form has two properties called MinimizeBox and MaximizeBox, set both of them to false.

To stop the form closing, handle the FormClosing event, and set e.Cancel = true; in there and after that, set WindowState = FormWindowState.Minimized;, to minimize the form.

Other than foreground/background term. Another way to hide running window is via vbscript, if is is still available in your system.

DIM objShell
set objShell=wscript.createObject("wscript.shell")
iReturn=objShell.Run("yourcommand.exe", 0, TRUE)

name it as sth.vbs and call it from bat, put in sheduled task, etc. PersonallyI'll disable vbs with no haste at any Windows system I manage :)

TypeScript is basically implementing rules and adding types to your code to make it more clear and more accurate due to the lack of constraints in Javascript. TypeScript requires you to describe your data, so that the compiler can check your code and find errors. The compiler will let you know if you are using mismatched types, if you are out of your scope or you try to return a different type. So, when you are using external libraries and modules with TypeScript, they need to contain files that describe the types in that code. Those files are called type declaration files with an extension d.ts. Most of the declaration types for npm modules are already written and you can include them using npm install @types/module_name (where module_name is the name of the module whose types you wanna include).

However, there are modules that don't have their type definitions and in order to make the error go away and import the module using import * as module_name from 'module-name', create a folder typings in the root of your project, inside create a new folder with your module name and in that folder create a module_name.d.ts file and write declare module 'module_name'. After this just go to your tsconfig.json file and add "typeRoots": [ "../../typings", "../../node_modules/@types"] in the compilerOptions (with the proper relative path to your folders) to let TypeScript know where it can find the types definitions of your libraries and modules and add a new property "exclude": ["../../node_modules", "../../typings"] to the file. Here is an example of how your tsconfig.json file should look like:

{
    "compilerOptions": {
        "module": "commonjs",
        "noImplicitAny": true,
        "sourceMap": true,
        "outDir": "../dst/",
        "target": "ESNEXT",
        "typeRoots": [
            "../../typings",
            "../../node_modules/@types"
        ]
    },
    "lib": [
            "es2016"
    ],
    "exclude": [
        "../../node_modules",
        "../../typings"
    ]
}

By doing this, the error will go away and you will be able to stick to the latest ES6 and TypeScript rules.

I solved mine by deleting the .settings folder and .project file in the project and then reimporting the project.

Try Toad for MySQL - its free and its great.
