Try HostingEnvironment.MapPath, which is static.

See this SO question for confirmation that HostingEnvironment.MapPath returns the same value as Server.MapPath: What is the difference between Server.MapPath and HostingEnvironment.MapPath?

The best I've seen so far is HtmlCleaner:

HtmlCleaner is open-source HTML parser written in Java. HTML found on Web is usually dirty, ill-formed and unsuitable for further processing. For any serious consumption of such documents, it is necessary to first clean up the mess and bring the order to tags, attributes and ordinary text. For the given HTML document, HtmlCleaner reorders individual elements and produces well-formed XML. By default, it follows similar rules that the most of web browsers use in order to create Document Object Model. However, user may provide custom tag and rule set for tag filtering and balancing.

With HtmlCleaner you can locate any element using XPath.

For other html parsers see this SO question.

You might wanna check out /etc/security/limits.conf

Maybe this answer here will help you. Seems that you want to dispose of the context periodically. This is because the context gets bigger and bigger as the attached entities grows.

<% @images.each_with_index do |page, index| %>

<% end %>

Here is how I've always done it:

    public static string Serialize(object obj) {
        using(MemoryStream memoryStream = new MemoryStream())
        using(StreamReader reader = new StreamReader(memoryStream)) {
            DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
            serializer.WriteObject(memoryStream, obj);
            memoryStream.Position = 0;
            return reader.ReadToEnd();
        }
    }

    public static object Deserialize(string xml, Type toType) {
        using(Stream stream = new MemoryStream()) {
            byte[] data = System.Text.Encoding.UTF8.GetBytes(xml);
            stream.Write(data, 0, data.Length);
            stream.Position = 0;
            DataContractSerializer deserializer = new DataContractSerializer(toType);
            return deserializer.ReadObject(stream);
        }
    }

Initially, the default value is fullscreen for modalPresentationStyle, but in iOS 13 its changes to the UIModalPresentationStyle.automatic.

If you want to make the full-screen view controller you have to change the modalPresentationStyle to fullScreen.

Refer UIModalPresentationStyle apple documentation for more details and refer apple human interface guidelines for where should use which modality.

I tried the update, but it did not work for me. Helped:

1. Uninstall NuGet => Tools => Extensions and update => Installed
2. Install NuGet
3. Reload Visual Studio

    $ conda install nb_conda_kernels

(in the conda environment where you run jupyter notebook) will make all conda envs available automatically. For access to other environments, the respective kernels must be installed. Here's the ref.

I like the approach of using a table with a column for each global variable. This way you get autocomplete to aid in coding the retrieval of the variable. The table can be restricted to a single row as outlined here: SQL Server: how to constrain a table to contain a single row?

way of getting home directory of current user is

String currentUsersHomeDir = System.getProperty("user.home");

and to append path separator

String otherFolder = currentUsersHomeDir + File.separator + "other";

File.separator

The system-dependent default name-separator character, represented as a string for convenience. This string contains a single character, namely separatorChar.

this worked for me :)

select * from Common

where

common_id not in (select ISNULL(common_id,'dummy-data') from Table1)

and common_id not in (select ISNULL(common_id,'dummy-data') from Table2)

1: The LayoutInflater takes your layout XML-files and creates different View-objects from its contents.

2: The adapters are built to reuse Views, when a View is scrolled so that is no longer visible, it can be used for one of the new Views appearing. This reused View is the convertView. If this is null it means that there is no recycled View and we have to create a new one, otherwise we should use it to avoid creating a new.

3: The parent is provided so you can inflate your view into that for proper layout parameters.

All these together can be used to effectively create the view that will appear in your list (or other view that takes an adapter):

public View getView(int position, @Nullable View convertView, ViewGroup parent){
    if (convertView == null) {
        //We must create a View:
        convertView = inflater.inflate(R.layout.my_list_item, parent, false);
    }
    //Here we can do changes to the convertView, such as set a text on a TextView 
    //or an image on an ImageView.
    return convertView;
}

Notice the use of the LayoutInflater, that parent can be used as an argument for it, and how convertView is reused.

I think Microsoft guide for ASP.NET Identity is a good start.

https://docs.microsoft.com/en-us/aspnet/identity/overview/features-api/account-confirmation-and-password-recovery-with-aspnet-identity

Note:

If you do not use AccountController and wan't to reset your password, use Request.GetOwinContext().GetUserManager<ApplicationUserManager>();. If you dont have the same OwinContext you need to create a new DataProtectorTokenProvider like the one OwinContext uses. By default look at App_Start -> IdentityConfig.cs. Should look something like new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));.

Could be created like this:

Without Owin:

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset()
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));

    var email = "[email protected]";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset(string token)
{
    var db = new ApplicationDbContext();
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
    var provider = new DpapiDataProtectionProvider("SampleAppName");
    manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
        provider.Create("SampleTokenName"));
    var email = "[email protected]";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

With Owin:

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin()
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "[email protected]";

    var user = new ApplicationUser() { UserName = email, Email = email };

    var identityUser = manager.FindByEmail(email);

    if (identityUser == null)
    {
        manager.Create(user);
        identityUser = manager.FindByEmail(email);
    }

    var token = manager.GeneratePasswordResetToken(identityUser.Id);
    return Ok(HttpUtility.UrlEncode(token));
}

[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin(string token)
{
    var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

    var email = "[email protected]";
    var identityUser = manager.FindByEmail(email);
    var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
    var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
    return Ok(result);
}

The DpapiDataProtectionProvider and DataProtectorTokenProvider needs to be created with the same name for a password reset to work. Using Owin for creating the password reset token and then creating a new DpapiDataProtectionProvider with another name won't work.

Code that I use for ASP.NET Identity:

Web.Config:

<add key="AllowedHosts" value="example.com,example2.com" />

AccountController.cs:

[Route("RequestResetPasswordToken/{email}/")]
[HttpGet]

        return NoContent();

    var result = await UserManager.ResetPasswordAsync(user.Id, model.Token, model.NewPassword);

    if (result.Succeeded)
    {
        Logger.Info("Creating password reset token for user id {0}", user.Id);

        const string subject = "Client - Password reset success.";
        var body = "<html><body>" +
                   "<h1>Your password for Client was reset</h1>" +

This Stack Overflow quesion is the current top Google result for "random string Python". The current top answer is:

''.join(random.choice(string.ascii_uppercase + string.digits) for _ in range(N))

This is an excellent method, but the PRNG in random is not cryptographically secure. I assume many people researching this question will want to generate random strings for encryption or passwords. You can do this securely by making a small change in the above code:

''.join(random.SystemRandom().choice(string.ascii_uppercase + string.digits) for _ in range(N))

Using random.SystemRandom() instead of just random uses /dev/urandom on *nix machines and CryptGenRandom() in Windows. These are cryptographically secure PRNGs. Using random.choice instead of random.SystemRandom().choice in an application that requires a secure PRNG could be potentially devastating, and given the popularity of this question, I bet that mistake has been made many times already.

If you're using python3.6 or above, you can use the new secrets module as mentioned in MSeifert's answer:

''.join(secrets.choice(string.ascii_uppercase + string.digits) for _ in range(N))

The module docs also discuss convenient ways to generate secure tokens and best practices.

Strange but it is a two step task:

1. Search what you want
2. In the search tab right click and select replace , or replace all:

A demo at:

http://www.avajava.com/tutorials/lessons/how-do-i-do-a-find-and-replace-in-multiple-files-in-eclipse.html

It's an array, so ==== '' won't work (the === means it has to be an empty string.)

Use count() to identify the array has any elements (count returns a number, 1 or greater will evaluate to true, 0 = false.)

@if (count($status->replies) > 0)
 // your HTML + foreach loop
@endif

I don't think you can do this in XML (at least not in Android), but I've found a good solution posted here that looks like it'd be a great help!

ShapeDrawable.ShaderFactory sf = new ShapeDrawable.ShaderFactory() {
    @Override
    public Shader resize(int width, int height) {
        LinearGradient lg = new LinearGradient(0, 0, width, height,
            new int[]{Color.GREEN, Color.GREEN, Color.WHITE, Color.WHITE},
            new float[]{0,0.5f,.55f,1}, Shader.TileMode.REPEAT);
        return lg;
    }
};

PaintDrawable p=new PaintDrawable();
p.setShape(new RectShape());
p.setShaderFactory(sf);

Basically, the int array allows you to select multiple color stops, and the following float array defines where those stops are positioned (from 0 to 1). You can then, as stated, just use this as a standard Drawable.

Edit: Here's how you could use this in your scenario. Let's say you have a Button defined in XML like so:

<Button
    android:id="@+id/thebutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Press Me!"
    />

You'd then put something like this in your onCreate() method:

Button theButton = (Button)findViewById(R.id.thebutton);
ShapeDrawable.ShaderFactory sf = new ShapeDrawable.ShaderFactory() {
    @Override
    public Shader resize(int width, int height) {
        LinearGradient lg = new LinearGradient(0, 0, 0, theButton.getHeight(),
            new int[] { 
                Color.LIGHT_GREEN, 
                Color.WHITE, 
                Color.MID_GREEN, 
                Color.DARK_GREEN }, //substitute the correct colors for these
            new float[] {
                0, 0.45f, 0.55f, 1 },
            Shader.TileMode.REPEAT);
         return lg;
    }
};
PaintDrawable p = new PaintDrawable();
p.setShape(new RectShape());
p.setShaderFactory(sf);
theButton.setBackground((Drawable)p);

I cannot test this at the moment, this is code from my head, but basically just replace, or add stops for the colors that you need. Basically, in my example, you would start with a light green, fade to white slightly before the center (to give a fade, rather than a harsh transition), fade from white to mid green between 45% and 55%, then fade from mid green to dark green from 55% to the end. This may not look exactly like your shape (Right now, I have no way of testing these colors), but you can modify this to replicate your example.

Edit: Also, the 0, 0, 0, theButton.getHeight() refers to the x0, y0, x1, y1 coordinates of the gradient. So basically, it starts at x = 0 (left side), y = 0 (top), and stretches to x = 0 (we're wanting a vertical gradient, so no left to right angle is necessary), y = the height of the button. So the gradient goes at a 90 degree angle from the top of the button to the bottom of the button.

Edit: Okay, so I have one more idea that works, haha. Right now it works in XML, but should be doable for shapes in Java as well. It's kind of complex, and I imagine there's a way to simplify it into a single shape, but this is what I've got for now:

green_horizontal_gradient.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <corners
        android:radius="3dp"
        />
    <gradient
        android:angle="0"
        android:startColor="#FF63a34a"
        android:endColor="#FF477b36"
        android:type="linear"
        />    
</shape>

half_overlay.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <solid
        android:color="#40000000"
        />
</shape>

layer_list.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android"
    >
    <item
        android:drawable="@drawable/green_horizontal_gradient"
        android:id="@+id/green_gradient"
        />
    <item
        android:drawable="@drawable/half_overlay"
        android:id="@+id/half_overlay"
        android:top="50dp"
        />
</layer-list>

test.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    >
    <TextView
        android:id="@+id/image_test"
        android:background="@drawable/layer_list"
        android:layout_width="fill_parent"
        android:layout_height="100dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:gravity="center"
        android:text="Layer List Drawable!"
        android:textColor="@android:color/white"
        android:textStyle="bold"
        android:textSize="26sp"     
        />
</RelativeLayout>

Okay, so basically I've created a shape gradient in XML for the horizontal green gradient, set at a 0 degree angle, going from the top area's left green color, to the right green color. Next, I made a shape rectangle with a half transparent gray. I'm pretty sure that could be inlined into the layer-list XML, obviating this extra file, but I'm not sure how. But okay, then the kind of hacky part comes in on the layer_list XML file. I put the green gradient as the bottom layer, then put the half overlay as the second layer, offset from the top by 50dp. Obviously you'd want this number to always be half of whatever your view size is, though, and not a fixed 50dp. I don't think you can use percentages, though. From there, I just inserted a TextView into my test.xml layout, using the layer_list.xml file as my background. I set the height to 100dp (twice the size of the offset of the overlay), resulting in the following:

Tada!

One more edit: I've realized you can just embed the shapes into the layer list drawable as items, meaning you don't need 3 separate XML files any more! You can achieve the same result combining them like so:

layer_list.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android"
    >
    <item>
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle"
            >
            <corners
                android:radius="3dp"
                />
            <gradient
                android:angle="0"
                android:startColor="#FF63a34a"
                android:endColor="#FF477b36"
                android:type="linear"
                />    
        </shape>
    </item>
    <item
        android:top="50dp" 
        >
        <shape
            android:shape="rectangle"
            >
            <solid
                android:color="#40000000"
                />
        </shape>            
    </item>
</layer-list>

You can layer as many items as you like this way! I may try to play around and see if I can get a more versatile result through Java.

I think this is the last edit...: Okay, so you can definitely fix the positioning through Java, like the following:

    TextView tv = (TextView)findViewById(R.id.image_test);
    LayerDrawable ld = (LayerDrawable)tv.getBackground();
    int topInset = tv.getHeight() / 2 ; //does not work!
    ld.setLayerInset(1, 0, topInset, 0, 0);
    tv.setBackgroundDrawable(ld);

However! This leads to yet another annoying problem in that you cannot measure the TextView until after it has been drawn. I'm not quite sure yet how you can accomplish this...but manually inserting a number for topInset does work.

I lied, one more edit

Okay, found out how to manually update this layer drawable to match the height of the container, full description can be found here. This code should go in your onCreate() method:

final TextView tv = (TextView)findViewById(R.id.image_test);
        ViewTreeObserver vto = tv.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                LayerDrawable ld = (LayerDrawable)tv.getBackground();
                ld.setLayerInset(1, 0, tv.getHeight() / 2, 0, 0);
            }
        });

And I'm done! Whew! :)

A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.

A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.

By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!

If only the incoming stream stalls for more than a millisecond you are running into a timeout.

Some of your dependencies are likely signed jarfiles. When you combine them all into one big jarfile, the corresponding signature files are still present, and no longer match the "big combined" jarfile, so the runtime halts thinking the jar file has been tampered with (which it...has so to speak).

Assuming you're using ant, you can solve the problem by eliminating the signature files from your jarfile dependencies. Unfortunately, it's not possible to do this in one step in ant.

However, I was able to get this working with Ant in two steps, without specifically naming each jarfile dependency, by using:

<target name="jar" depends="compile" description="Create one big jarfile.">
    <jar jarfile="${output.dir}/deps.jar">
        <zipgroupfileset dir="jars">
            <include name="**/*.jar" />
        </zipgroupfileset>
    </jar>
    <sleep seconds="1" />
    <jar jarfile="${output.dir}/myjar.jar" basedir="${classes.dir}">
        <zipfileset src="${output.dir}/deps.jar" excludes="META-INF/*.SF" />
        <manifest>
            <attribute name="Main-Class" value="com.mycompany.MyMain" />
        </manifest>
    </jar>
</target>

The sleep element is supposed to prevent errors about files with modification dates in the future.

Other variations I found in the linked threads didn't work for me.

Simon's answer and Volcano's together explain what you're doing wrong, and Simon explains how you can fix it by redesigning your interface.

But if you really need to read 1 character, and then later read 1 line, you can do that. It's not trivial, and it's different on Windows vs. everything else.

There are actually three cases: a Unix tty, a Windows DOS prompt, or a regular file (redirected file/pipe) on either platform. And you have to handle them differently.

First, to check if stdin is a tty (both Windows and Unix varieties), you just call sys.stdin.isatty(). That part is cross-platform.

For the non-tty case, it's easy. It may actually just work. If it doesn't, you can just read from the unbuffered object underneath sys.stdin. In Python 3, this just means sys.stdin.buffer.raw.read(1) and sys.stdin.buffer.raw.readline(). However, this will get you encoded bytes, rather than strings, so you will need to call .decode(sys.stdin.decoding) on the results; you can wrap that all up in a function.

For the tty case on Windows, however, input will still be line buffered even on the raw buffer. The only way around this is to use the Console I/O functions instead of normal file I/O. So, instead of stdin.read(1), you do msvcrt.getwch().

For the tty case on Unix, you have to set the terminal to raw mode instead of the usual line-discipline mode. Once you do that, you can use the same sys.stdin.buffer.read(1), etc., and it will just work. If you're willing to do that permanently (until the end of your script), it's easy, with the tty.setraw function. If you want to return to line-discipline mode later, you'll need to use the termios module. This looks scary, but if you just stash the results of termios.tcgetattr(sys.stdin.fileno()) before calling setraw, then do termios.tcsetattr(sys.stdin.fileno(), TCSAFLUSH, stash), you don't have to learn what all those fiddly bits mean.

On both platforms, mixing console I/O and raw terminal mode is painful. You definitely can't use the sys.stdin buffer if you've ever done any console/raw reading; you can only use sys.stdin.buffer.raw. You could always replace readline by reading character by character until you get a newline… but if the user tries to edit his entry by using backspace, arrows, emacs-style command keys, etc., you're going to get all those as raw keypresses, which you don't want to deal with.

Try this

SqlCommand cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID=@id", con);
cmd.Parameters.AddWithValue("id", id.Text);

If using Xcode 4.2 or higher, try the following:

1. Click your Project name (in the left column), followed by the Target:

   

2. Click the 'Build Settings' tab (in the right column):

   

3. Click the 'Release' or 'Distribution' row under 'Architectures', and choose 'Other...':

   

4. Double click the highlighted row named '$(ARCHS_STANDARD_32_BIT)' in the popover that appears, and replace it by typing 'armv6'. Then add a new row with the plus button in the bottom left of the popover, and type 'armv7', then click Done:

   

Update: you should add armv7s to target the iPhone 5 as well. (And drop armv6 if building with Xcode 4.5 or higher, which no longer supports armv6.)

That's it. You should now be able to build/archive without generating errors.

If it still doesn't work, see this answer from justinxreese, which suggests adding entries for armv6 and armv7 under "Required Device Capabilities" in your info.plist file.

I was unable to get Pavel's answer working as in when posting to a Web.Api application.

The issue appears to be with the deleting of the headers.

headersGetter();
delete headers['Content-Type'];

In order to ensure the browsers was allowed to default the Content-Type along with the boundary parameter, I needed to set the Content-Type to undefined. Using Pavel's example the boundary was never being set resulting in a 400 HTTP exception.

The key was to remove the code deleting the headers shown above and to set the headers content type to null manually. Thus allowing the browser to set the properties.

headers: {'Content-Type': undefined}

Here is a full example.

$scope.Submit = form => {
                $http({
                    method: 'POST',
                    url: 'api/FileTest',
                    headers: {'Content-Type': undefined},
                    data: {
                        FullName: $scope.FullName,
                        Email: $scope.Email,
                        File1: $scope.file
                    },
                    transformRequest: function (data, headersGetter) {
                        var formData = new FormData();
                        angular.forEach(data, function (value, key) {
                            formData.append(key, value);
                        });
                        return formData;
                    }
                })
                .success(function (data) {

                })
                .error(function (data, status) {

                });

                return false;
            }

I would generally try to avoid the use of #pragmas if possible, since they're extremely compiler-dependent and non-portable. If you want to use them in a portable fashion, you'll have to surround every pragma with a #if/#endif pair. GCC discourages the use of pragmas, and really only supports some of them for compatibility with other compilers; GCC has other ways of doing the same things that other compilers use pragmas for.

For example, here's how you'd ensure that a structure is packed tightly (i.e. no padding between members) in MSVC:

#pragma pack(push, 1)
struct PackedStructure
{
  char a;
  int b;
  short c;
};
#pragma pack(pop)
// sizeof(PackedStructure) == 7

Here's how you'd do the same thing in GCC:

struct PackedStructure __attribute__((__packed__))
{
  char a;
  int b;
  short c;
};
// sizeof(PackedStructure == 7)

The GCC code is more portable, because if you want to compile that with a non-GCC compiler, all you have to do is

#define __attribute__(x)

Whereas if you want to port the MSVC code, you have to surround each pragma with a #if/#endif pair. Not pretty.

I think you are looking for below method:

var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
    var friends= db.Friends.Where(f=>idList.Contains(f.ID));
    friends.ForEachAsync(a=>a.msgSentBy='1234');
    await db.SaveChangesAsync();
}

This should be the efficient way of handling this.

I don't believe AJAX can handle file uploads but this can be achieved with libraries that leverage flash. Another advantage of the flash implementation is the ability to do multiple files at once (like gmail).

SWFUpload is a good start : http://www.swfupload.org/documentation

jQuery and some of the other libraries have plugins that leverage SWFUpload. On my last project we used SWFUpload and Java without a problem.

Also helpful and worth looking into is Apache's FileUpload : http://commons.apache.org/fileupload/index.html

Here's another solution that uses some of VBA's built in date functions and stores all the date data in an array for comparison, which may give better performance if you get a lot of data:

Public Sub MoveData(MonthNum As Integer, FromSheet As Worksheet, ToSheet As Worksheet)
    Const DateCol = "A" 'column where dates are store
    Const DestCol = "A" 'destination column where dates are stored. We use this column to find the last populated row in ToSheet
    Const FirstRow = 2 'first row where date data is stored
    'Copy range of values to Dates array
    Dates = FromSheet.Range(DateCol & CStr(FirstRow) & ":" & DateCol & CStr(FromSheet.Range(DateCol & CStr(FromSheet.Rows.Count)).End(xlUp).Row)).Value
    Dim i As Integer
    For i = LBound(Dates) To UBound(Dates)
        If IsDate(Dates(i, 1)) Then
            If Month(CDate(Dates(i, 1))) = MonthNum Then
                Dim CurrRow As Long
                'get the current row number in the worksheet
                CurrRow = FirstRow + i - 1
                Dim DestRow As Long
                'get the destination row
                DestRow = ToSheet.Range(DestCol & CStr(ToSheet.Rows.Count)).End(xlUp).Row + 1
                'copy row CurrRow in FromSheet to row DestRow in ToSheet
                FromSheet.Range(CStr(CurrRow) & ":" & CStr(CurrRow)).Copy ToSheet.Range(DestCol & CStr(DestRow))
            End If
        End If
    Next i
End Sub

I did try using a Monitor (code below) which appears to work but has a GOTCHA... when you have multiple threads it will give... System.Threading.SynchronizationLockException Object synchronization method was called from an unsynchronized block of code.

using System;
using System.Threading;
using System.Threading.Tasks;

namespace MyNamespace
{
    public class ThreadsafeFooModifier : 
    {
        private readonly object _lockObject;

        public async Task<FooResponse> ModifyFooAsync()
        {
            FooResponse result;
            Monitor.Enter(_lockObject);
            try
            {
                result = await SomeFunctionToModifyFooAsync();
            }
            finally
            {
                Monitor.Exit(_lockObject);
            }
            return result;
        }
    }
}

Prior to this I was simply doing this, but it was in an ASP.NET controller so it resulted in a deadlock.

public async Task<FooResponse> ModifyFooAsync() { lock(lockObject) { return SomeFunctionToModifyFooAsync.Result; } }

If this is for an intranet application and all of the clients use DHCP, you can query the DHCP server for the MAC address for a given IP address.

I encountered this exception message as well. For me the problem was different. I wanted to delete a parent.

In one transaction:

• First I called up the parent from the database.
• Then I called a child element from a collection in the parent.
• Then I referenced one field in the child (id)
• Then I deleted the parent.
• Then I called commit.
• I got the "deleted object would be resaved" error.

It turns out that I had to do two separate transactions. I committed after referencing the field in the child. Then started a new commit for the delete.

There was no need to delete the child elements or empty the collections in the parent (assuming orphanRemoval = true.). In fact, this didn't work.

In sum, this error appears if you have a reference to a field in a child object when that object is being deleted.

Note : This answer is now out-of-date. This changes the theme in "preview" only as @imjohnking and @john-ktejik pointed out. As @Shahzeb mentioned, theme can modified in res>values>styles

Android Studio 0.8.2 provides a slightly easier way to change the theme. In the preview window, you can select the theme of "Holo.Light.DarkActionBar" by clicking on the theme combo box just above the phone.

Or do a ctrl + click on the @style/AppTheme in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

• Theme.Holo for a "dark" theme.
• Theme.Holo.Light for a "light" theme.

When using the Support Library, you must instead use the Theme.AppCompat themes:

• Theme.AppCompat for the "dark" theme.
• Theme.AppCompat.Light for the "light" theme.
• Theme.AppCompat.Light.DarkActionBar for the light theme with a dark action bar.

Since the accepted answer and also the next highest voted answer have, in my opinion, some problems, I'd like to offer one more answer that is based closely on Ihor B.'s answer with some small but important modifications.

This solution allows you to run profiling on either by wrapping a function call with the profile function and calling it, or by decorating your function/method with the @profile decorator.

The first technique is useful when you want to profile some third-party code without messing with its source, whereas the second technique is a bit "cleaner" and works better when you are don't mind modifying the source of the function/method you want to profile.

I've also modified the output, so that you get RSS, VMS, and shared memory. I don't care much about the "before" and "after" values, but only the delta, so I removed those (if you're comparing to Ihor B.'s answer).

Profiling code

# profile.py
import time
import os
import psutil
import inspect


def elapsed_since(start):
    #return time.strftime("%H:%M:%S", time.gmtime(time.time() - start))
    elapsed = time.time() - start
    if elapsed < 1:
        return str(round(elapsed*1000,2)) + "ms"
    if elapsed < 60:
        return str(round(elapsed, 2)) + "s"
    if elapsed < 3600:
        return str(round(elapsed/60, 2)) + "min"
    else:
        return str(round(elapsed / 3600, 2)) + "hrs"


def get_process_memory():
    process = psutil.Process(os.getpid())
    mi = process.memory_info()
    return mi.rss, mi.vms, mi.shared


def format_bytes(bytes):
    if abs(bytes) < 1000:
        return str(bytes)+"B"
    elif abs(bytes) < 1e6:
        return str(round(bytes/1e3,2)) + "kB"
    elif abs(bytes) < 1e9:
        return str(round(bytes / 1e6, 2)) + "MB"
    else:
        return str(round(bytes / 1e9, 2)) + "GB"


def profile(func, *args, **kwargs):
    def wrapper(*args, **kwargs):
        rss_before, vms_before, shared_before = get_process_memory()
        start = time.time()
        result = func(*args, **kwargs)
        elapsed_time = elapsed_since(start)
        rss_after, vms_after, shared_after = get_process_memory()
        print("Profiling: {:>20}  RSS: {:>8} | VMS: {:>8} | SHR {"
              ":>8} | time: {:>8}"
            .format("<" + func.__name__ + ">",
                    format_bytes(rss_after - rss_before),
                    format_bytes(vms_after - vms_before),
                    format_bytes(shared_after - shared_before),
                    elapsed_time))
        return result
    if inspect.isfunction(func):
        return wrapper
    elif inspect.ismethod(func):
        return wrapper(*args,**kwargs)

Example usage, assuming the above code is saved as profile.py:

from profile import profile
from time import sleep
from sklearn import datasets # Just an example of 3rd party function call


# Method 1
run_profiling = profile(datasets.load_digits)
data = run_profiling()

# Method 2
@profile
def my_function():
    # do some stuff
    a_list = []
    for i in range(1,100000):
        a_list.append(i)
    return a_list


res = my_function()

This should result in output similar to the below:

Profiling:        <load_digits>  RSS:   5.07MB | VMS:   4.91MB | SHR  73.73kB | time:  89.99ms
Profiling:        <my_function>  RSS:   1.06MB | VMS:   1.35MB | SHR       0B | time:   8.43ms

A couple of important final notes:

1. Keep in mind, this method of profiling is only going to be approximate, since lots of other stuff might be happening on the machine. Due to garbage collection and other factors, the deltas might even be zero.
2. For some unknown reason, very short function calls (e.g. 1 or 2 ms) show up with zero memory usage. I suspect this is some limitation of the hardware/OS (tested on basic laptop with Linux) on how often memory statistics are updated.
3. To keep the examples simple, I didn't use any function arguments, but they should work as one would expect, i.e. profile(my_function, arg) to profile my_function(arg)

The Servlet 2.4 specification says this about WEB-INF (page 70):

A special directory exists within the application hierarchy named WEB-INF. This directory contains all things related to the application that aren’t in the document root of the application. The WEB-INF node is not part of the public document tree of the application. No file contained in the WEB-INF directory may be served directly to a client by the container. However, the contents of the WEB-INF directory are visible to servlet code using the getResource and getResourceAsStream method calls on the ServletContext, and may be exposed using the RequestDispatcher calls.

This means that WEB-INF resources are accessible to the resource loader of your Web-Application and not directly visible for the public.

This is why a lot of projects put their resources like JSP files, JARs/libraries and their own class files or property files or any other sensitive information in the WEB-INF folder. Otherwise they would be accessible by using a simple static URL (usefull to load CSS or Javascript for instance).

Your JSP files can be anywhere though from a technical perspective. For instance in Spring you can configure them to be in WEB-INF explicitly:

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
    p:prefix="/WEB-INF/jsp/" 
    p:suffix=".jsp" >
</bean>

The WEB-INF/classes and WEB-INF/lib folders mentioned in Wikipedia's WAR files article are examples of folders required by the Servlet specification at runtime.

It is important to make the difference between the structure of a project and the structure of the resulting WAR file.

The structure of the project will in some cases partially reflect the structure of the WAR file (for static resources such as JSP files or HTML and JavaScript files, but this is not always the case.

The transition from the project structure into the resulting WAR file is done by a build process.

While you are usually free to design your own build process, nowadays most people will use a standardized approach such as Apache Maven. Among other things Maven defines defaults for which resources in the project structure map to what resources in the resulting artifact (the resulting artifact is the WAR file in this case). In some cases the mapping consists of a plain copy process in other cases the mapping process includes a transformation, such as filtering or compiling and others.

One example: The WEB-INF/classes folder will later contain all compiled java classes and resources (src/main/java and src/main/resources) that need to be loaded by the Classloader to start the application.

Another example: The WEB-INF/lib folder will later contain all jar files needed by the application. In a maven project the dependencies are managed for you and maven automatically copies the needed jar files to the WEB-INF/lib folder for you. That explains why you don't have a lib folder in a maven project.

All modern terminal emulators use ANSI escape codes to show colours and other things.
Don't bother with libraries, the code is really simple.

More info is here.

Example in C:

#include <stdio.h>

#define ANSI_COLOR_RED     "\x1b[31m"
#define ANSI_COLOR_GREEN   "\x1b[32m"
#define ANSI_COLOR_YELLOW  "\x1b[33m"
#define ANSI_COLOR_BLUE    "\x1b[34m"
#define ANSI_COLOR_MAGENTA "\x1b[35m"
#define ANSI_COLOR_CYAN    "\x1b[36m"
#define ANSI_COLOR_RESET   "\x1b[0m"

int main (int argc, char const *argv[]) {

  printf(ANSI_COLOR_RED     "This text is RED!"     ANSI_COLOR_RESET "\n");
  printf(ANSI_COLOR_GREEN   "This text is GREEN!"   ANSI_COLOR_RESET "\n");
  printf(ANSI_COLOR_YELLOW  "This text is YELLOW!"  ANSI_COLOR_RESET "\n");
  printf(ANSI_COLOR_BLUE    "This text is BLUE!"    ANSI_COLOR_RESET "\n");
  printf(ANSI_COLOR_MAGENTA "This text is MAGENTA!" ANSI_COLOR_RESET "\n");
  printf(ANSI_COLOR_CYAN    "This text is CYAN!"    ANSI_COLOR_RESET "\n");

  return 0;
}

Lets check how the comparison with null is defined:

static void Main()
    {
        Console.WriteLine($"null != null  => {null != null}");
        Console.WriteLine($"null == null  => {null == null}");
        Console.WriteLine($"null != true  => {null != true}");
        Console.WriteLine($"null == true  => {null == true}");
        Console.WriteLine($"null != false => {null != false}");
        Console.WriteLine($"null == false => {null == false}");
    }

and the results are:

null != null  => False                                                                                                                                                                                                                                  
null == null  => True                                                                                                                                                                                                                                   
null != true  => True                                                                                                                                                                                                                                   
null == true  => False                                                                                                                                                                                                                                  
null != false => True                                                                                                                                                                                                                                   
null == false => False

So you can safely use:

// check if null or false
if (nullable != true) ...

// check if null or true
if (nullable != false) ...

// check if true or false
if (nullable != null) ...

because your Information action method require id parameter, and your route collection has id of your current requested url(/Admin/Information/5), id parameter automatically gotten from existing route collection values.

to solve this problem you should use UrlParameter.Optional:

 <a href="@Url.Action("Information", "Admin", new { id = UrlParameter.Optional })">Add an Admin</a>

Its always better to go for a generic reusable function in your project which returns whether the extension loaded. You can use the following function to check -

function isExtensionLoaded($extension_name){
    return extension_loaded($extension_name);
}

Usage

echo isExtensionLoaded('curl');
echo isExtensionLoaded('gd');

You can also get the API key in the android studio. Switch to Project view in android then find the google-services.json. Scroll down and you will find the api_key

You can open the ".git" directory and then edit the "config" file. Under "[core]" set, set "ignorecase = true" and you are done ;)

That's a great post. Before making all the changes to vcvarsall.bat file, try running vs2010 command prompt as an administrator. If that still doesn't address the issue, try adding C:\Windows\System32 to the PATH environment variable. If all else fails, edit the batch file as described above.

You can use the built-in JavaScript debugger in Chrome Developer Tools under the "Scripts" tab (in later versions it's the "Sources" tab), but changes you apply to the code are expressed only at the time when execution passes through them. That means changes to the code that is not running after the page loads will not have an effect. Unlike e.g. changes to the code residing in the mouseover handlers, which you can test on the fly.

There is a video from Google I/O 2010 event introducing other capabilities of Chrome Developer Tools.

If you want to create and submit your form from Javascript as is in your question and you want to create popup window with custom features I propose this solution (I put comments above the lines i added):

var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "test.jsp");

// setting form target to a window named 'formresult'
form.setAttribute("target", "formresult");

var hiddenField = document.createElement("input");              
hiddenField.setAttribute("name", "id");
hiddenField.setAttribute("value", "bob");
form.appendChild(hiddenField);
document.body.appendChild(form);

// creating the 'formresult' window with custom features prior to submitting the form
window.open('test.html', 'formresult', 'scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');

form.submit();

$(function() {
    $('input:radio[name="myRadios"]').change(function() {

Yes. Please see the man page of bash ( the first thing you go to ) under Special Parameters

Special Parameters

The shell treats several parameters specially. These parameters may only be referenced; assignment to them is not allowed.

* Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

@ Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

try this

 $("input:checked", "#radioButton").val()

if checked returns True if not checked returns False

jQuery v1.10.1

It only opens the first (bookmarked) page full screen. Any next page will be opened WITH the address bar visible again. Whatever meta tag you put into your page header...

The doxypy input filter allows you to use pretty much all of Doxygen's formatting tags in a standard Python docstring format. I use it to document a large mixed C++ and Python game application framework, and it's working well.

There is confusing when you are using data picker, for bootstrap datepicker you have to use following code:-

$( ".datepicker" ).datepicker({
   format: 'yyyy-mm-dd'
});

and for jquery datepicker following code must be used:-

$( ".datepicker" ).datepicker({
       dateFormat: 'dd-mm-yy'
    });

So you must be aware which date picker you are using, that is ultimately solve your issue, Hope this hepls you.

Ultimately the best (though annoying) answer is "escape the text".

There are however a lot of text editors -- or even stand-alone mini utilities -- that can do this automatically. So you never should have to escape it manually if you don't want to (Unless it's a mix of escaped and un-escaped code...)

Quick Google search shows me this one, for example: http://malektips.com/zzee-text-utility-html-escape-regular-expression.html

Here is a link which is useful to learn about select a siblings element in Jquery.

How do I select a sibling element using jQuery

$("selector").nextAll(); 
$("selector").prev(); 

you can also find an element using Jquery selector

$("h2").siblings('table').find('tr'); 

For more information, refer this link next(), nextAll(), prev(), prevAll(), find() and siblings in JQuery

In your code you are missing Class.forName("com.mysql.jdbc.Driver");

This is what you are missing to have everything working.

You need to use display: table-row instead of float: left; to your column and obviously as @Hushme correct your diaplay: table-cell to display: table-cell;

 .container {
    display: table;
    border-collapse: collapse;
}
.column {
    display: table-row;
    overflow: hidden;
    width: 120px;
}
.cell {
    display: table-cell;
    border: 1px solid red;
    width: 120px;
    height: 20px;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}

Try putting it in a span element:

<div id='page' style='width: 600px'>_x000D_
  <h1><span style='border:2px black solid; font-size:42px;'>Title</span></h1>_x000D_
</div>

Just to add to other answers, if you're using Django, it is advisable that you install mysql-python BEFORE installing Django.

What worked for me in python 3.7 and img2pdf version 0.4.0 was to use something similar to the code given by Syed Shamikh Shabbir but changing the current working directory using OS as Stu suggested in his comment to Syed's solution

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

for image in images:
    with open(image[:-4] + ".pdf", "wb") as f:
        f.write(img2pdf.convert(image))

It is worth mentioning this solution above saves each .jpg separately in one single pdf. If you want all your .jpg files together in only one .pdf you could do:

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

with open("output.pdf", "wb") as f:
    f.write(img2pdf.convert(images))

I feel it would be helpful for someone who is looking for passing the array in a query string to a servlet. I tested below query string and was able to get the array values using req.getgetParameterValues(); method. Below is the query string I passed through browser.

  http://localhost:8080/ServletsTutorials/*.html? 
  myname=abc&initial=xyz&checkbox=a&checkbox=b

checkbox is my parameter array here.

In the Node.js REPL:

> Array.from({length:5}).map(x => 2)
[ 2, 2, 2, 2, 2 ]

Modern async/await way ( Node 12.8.x )

const fileExists = async path => !!(await fs.promises.stat(path).catch(e => false));

const main = async () => {
    console.log(await fileExists('/path/myfile.txt'));
}

main();

We need to use fs.stat() or fs.access() because fs.exists(path, callback) now is deprecated

Another good way is fs-extra

As per java doc's

Hashtable and Collections.synchronizedMap(new HashMap()) are synchronized. But ConcurrentHashMap is "concurrent".

A concurrent collection is thread-safe, but not governed by a single exclusion lock.

In the particular case of ConcurrentHashMap, it safely permits any number of concurrent reads as well as a tunable number of concurrent writes. "Synchronized" classes can be useful when you need to prevent all access to a collection via a single lock, at the expense of poorer scalability.

In other cases in which multiple threads are expected to access a common collection, "concurrent" versions are normally preferable. And unsynchronized collections are preferable when either collections are unshared, or are accessible only when holding other locks.

I have solved the same problem with you,here is my operation environment( System:linux Versions:python 3.6 Package:Pyhive) please refer to my answer as follows:

from pyhive import hive
conn = hive.Connection(host='149.129.***.**', port=10000, username='*', database='*',password="*",auth='LDAP')

The key point is to add the reference password & auth and meanwhile set the auth equal to 'LDAP' . Then it works well, any questions please let me know

Does the race conditions really matter if you first try an update followed by an insert? Lets say you have two threads that want to set a value for key key:

Thread 1: value = 1
Thread 2: value = 2

Example race condition scenario

1. key is not defined
2. Thread 1 fails with update
3. Thread 2 fails with update
4. Exactly one of thread 1 or thread 2 succeeds with insert. E.g. thread 1

5. The other thread fails with insert (with error duplicate key) - thread 2.

   • Result: The "first" of the two treads to insert, decides value.
   • Wanted result: The last of the 2 threads to write data (update or insert) should decide value

But; in a multithreaded environment, the OS scheduler decides on the order of the thread execution - in the above scenario, where we have this race condition, it was the OS that decided on the sequence of execution. Ie: It is wrong to say that "thread 1" or "thread 2" was "first" from a system viewpoint.

When the time of execution is so close for thread 1 and thread 2, the outcome of the race condition doesn't matter. The only requirement should be that one of the threads should define the resulting value.

For the implementation: If update followed by insert results in error "duplicate key", this should be treated as success.

Also, one should of course never assume that value in the database is the same as the value you wrote last.

Remove everything, but this:

Align(
  alignment: Alignment.bottomCenter,
  child: new ButtonBar(
    alignment: MainAxisAlignment.center,
    children: <Widget>[
      new OutlineButton(
        onPressed: () {
          Navigator.push(
            context,
            new MaterialPageRoute(
              builder: (context) => new LoginPage()));
        },
        child: new Text(
          "Login",
          style: new TextStyle(color: Colors.white),
        ),
      ),
      new RaisedButton(
        color: Colors.white,
        onPressed: () {
          Navigator.push(
            context,
            new MaterialPageRoute(
              builder: (context) =>
                new RegistrationPage()));
        },
        child: new Text(
          "Register",
          style: new TextStyle(color: Colors.black),
        ),
      )
    ],
  ),
)

In my theory, the additional Container is destroying it. I would advise you to just surround this by adding Padding:

Padding(
  padding: EdgeInsets.only(bottom: 20.0),
  child: Align...
),

This seems a lot more reasonable to me than the Positioned and also I do not quite understand your Column with a single child only.

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

brbcoding have been able to help me with the appropriate coding i needed, here is it

HTML

<input type="checkbox" id="checkme"/>
  <input type="submit" name="sendNewSms" class="inputButton" disabled="disabled" id="sendNewSms" value=" Send " />

Javascript

 var checker = document.getElementById('checkme');
 var sendbtn = document.getElementById('sendNewSms');
 // when unchecked or checked, run the function
 checker.onchange = function(){
if(this.checked){
    sendbtn.disabled = false;
} else {
    sendbtn.disabled = true;
}

}

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

create two Date objects and call valueOf() on both, then compare them.

JavaScript Date Object Reference

As of Python 3.7, datetime.datetime.fromisoformat() can handle your format:

>>> import datetime
>>> datetime.datetime.fromisoformat('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(days=-1, seconds=72000)))

In older Python versions you can't, not without a whole lot of painstaking manual timezone defining.

Python does not include a timezone database, because it would be outdated too quickly. Instead, Python relies on external libraries, which can have a far faster release cycle, to provide properly configured timezones for you.

As a side-effect, this means that timezone parsing also needs to be an external library. If dateutil is too heavy-weight for you, use iso8601 instead, it'll parse your specific format just fine:

>>> import iso8601
>>> iso8601.parse_date('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=<FixedOffset '-04:00'>)

iso8601 is a whopping 4KB small. Compare that tot python-dateutil's 148KB.

As of Python 3.2 Python can handle simple offset-based timezones, and %z will parse -hhmm and +hhmm timezone offsets in a timestamp. That means that for a ISO 8601 timestamp you'd have to remove the : in the timezone:

>>> from datetime import datetime
>>> iso_ts = '2012-11-01T04:16:13-04:00'
>>> datetime.strptime(''.join(iso_ts.rsplit(':', 1)), '%Y-%m-%dT%H:%M:%S%z')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(-1, 72000)))

The lack of proper ISO 8601 parsing is being tracked in Python issue 15873.

As i was also stuck in this, think i should share the solution that worked best for me. I also think that this is much simpler.

If you use Capitalized table name.

SELECT CONCAT("firstName", ' ', "lastName") FROM "User"

If you use lowercase table name

SELECT CONCAT(firstName, ' ', lastName) FROM user

That's it!. As PGSQL counts Double Quote for column declaration and Single Quote for string, this works like a charm.

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

I had to be absolutely sure the view was not just removed from DOM but also completely unbound from events.

destroy_view: function() {

    // COMPLETELY UNBIND THE VIEW
    this.undelegateEvents();

    this.$el.removeData().unbind(); 

    // Remove view from DOM
    this.remove();  
    Backbone.View.prototype.remove.call(this);

}

Seemed like overkill to me, but other approaches did not completely do the trick.

I started out naming enums in the plural but have since changed to singular. Just seems to make more sense in the context of where they're used.

enum Status { Unknown = 0, Incomplete, Ready }

Status myStatus = Status.Ready;

Compare to:

Statuses myStatus = Statuses.Ready;

I find the singular form to sound more natural in context. We are in agreement that when declaring the enum, which happens in one place, we're thinking "this is a group of whatevers", but when using it, presumably in many places, that we're thinking "this is one whatever".

For Python 3, you have to decode the data you get back from the web server. For instance I decode the data as utf8 then deal with it:

 # example of json data object group with two values of key id
jsonstufftest = '{'group':{'id':'2','id':'3'}}
 # always set your headers
headers = {'User-Agent': 'Moz & Woz'}
 # the url you are trying to load and get json from
url = 'http://www.cooljson.com/cooljson.json'
 # in python 3 you can build the request using request.Request
req = urllib.request.Request(url,None,headers)
 # try to connect or fail gracefully
try:
    response = urllib.request.urlopen(req) # new python 3 code -jc
except:
    exit('could not load page, check connection')
 # read the response and DECODE
html=response.read().decode('utf8') # new python3 code
 # now convert the decoded string into real JSON
loadedjson = json.loads(html)
 # print to make sure it worked
print (loadedjson) # works like a charm
 # iterate through each key value
for testdata in loadedjson['group']:
    print (accesscount['id']) # should print 2 then 3 if using test json

If you don't decode you will get bytes vs string errors in Python 3.

The align-items, or respectively align-content attribute controls this behaviour.

align-items defines the items' positioning perpendicularly to flex-direction.

The default flex-direction is row, therfore vertical placement can be controlled with align-items.

There is also the align-self attribute to control the alignment on a per item basis.

#a {_x000D_
  display:flex;_x000D_
_x000D_
  align-items:flex-start;_x000D_
  align-content:flex-start;_x000D_
  }_x000D_
_x000D_
#a > div {_x000D_
  _x000D_
  background-color:red;_x000D_
  padding:5px;_x000D_
  margin:2px;_x000D_
  }_x000D_
 #a > #c {_x000D_
  align-self:stretch;_x000D_
 }

<div id="a">_x000D_
  _x000D_
  <div id="b">left</div>_x000D_
  <div id="c">middle</div>_x000D_
  <div>right<br>right<br>right<br>right<br>right<br></div>_x000D_

</div>

css-tricks has an excellent article on the topic. I recommend reading it a couple of times.

1. Inside your lib file

2. Create a folder called colors.

3. Inside the colors folder create a dart file and name it color.

4. Paste this code inside it

   const MaterialColor primaryOrange = MaterialColor(
       _orangePrimaryValue,
       <int, Color>{
           50: Color(0xFFFF9480),
           100: Color(0xFFFF9480),
           200: Color(0xFFFF9480),
           300: Color(0xFFFF9480),
           400: Color(0xFFFF9480),
           500: Color(0xFFFF9480),
           600: Color(0xFFFF9480),
           700: Color(0xFFFF9480),
           800: Color(0xFFFF9480),
           900: Color(0xFFFF9480),
       },
   );
   const int _orangePrimaryValue = 0xFFFF9480;
   

5. Go to your main.dart file and place this code in your theme

   theme:ThemeData(
       primarySwatch: primaryOrange,
   ),
   

6. Import the color folder in your main.dart like this import 'colors/colors.dart';

Had a similar issue. Here are the steps used to setup SSH keys and forwarding on the Mac. Made these notes for myself - may help someone... check against your config.

The assumption here is there are no keys setup. If you already have the keys setup skip this section.

$ ssh-keygen -t rsa -b 4096

Generating public/private rsa key pair.

Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter] Enter passphrase (empty for no passphrase): [Type a passphrase] Enter same passphrase again: [Type passphrase again]

Modify ~/.ssh/config adding the entry for the key file:

~/.ssh/config should look similar to:

Host *

AddKeysToAgent yes

UseKeychain yes

IdentityFile ~/.ssh/id_rsa

Store the private key in the keychain:

$ ssh-add -K ~/.ssh/id_rsa

Go test it now with: ssh -A username@yourhostname

Should forward your key to yourhostname. Assuming your keys are added on you should connect without issue.

Oracle SQL:

There is the "IN" Operator in Oracle SQL which can be used for that:

select 
    namet.customerfirstname, addrt.city, addrt.postalcode
from schemax.nametable namet
join schemax.addresstable addrt on addrt.adtid = namet.natadtid
where namet.customerfirstname in ('David', 'Moses', 'Robi'); 

Another (silly) possibility is to git commit --amend <<< :wq if you've got vi(m) as $EDITOR.

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

Since this came up on a Google search for "javascript get number of digits", I wanted to throw it out there that there is a shorter alternative to this that relies on internal casting to be done for you:

var int_number = 254;
var int_length = (''+int_number).length;

var dec_number = 2.12;
var dec_length = (''+dec_number).length;

console.log(int_length, dec_length);

Yields

3 4

            $error = array('error' => $this->upload->display_errors());
            $this->load->view('production/create_images', $error);
        } else {
            $upload_data = $this->upload->data();   
        }

The above solution left blue border around each cell in my case.

This is the solution that worked for me. It is very simple, just add this to your DataGrid. You can change it from a SolidColorBrush to any other brush such as linear gradient.

<DataGrid.Resources>
  <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" 
                   Color="#FF0000"/>
</DataGrid.Resources>

if re.search(r'pattern', string):

Simple if-test:

if re.search(r'ing\b', "seeking a great perhaps"):     # any words end with ing?
    print("yes")

Pattern check, extract a substring, case insensitive:

match_object = re.search(r'^OUGHT (.*) BE$', "ought to be", flags=re.IGNORECASE)
if match_object:
    assert "to" == match_object.group(1)     # what's between ought and be?

Notes:

• Use re.search() not re.match. Match restricts to the start of strings, a confusing convention if you ask me. If you do want a string-starting match, use caret or \A instead, re.search(r'^...', ...)

• Use raw string syntax r'pattern' for the first parameter. Otherwise you would need to double up backslashes, as in re.search('ing\\b', ...)

• In this example, \b is a special sequence meaning word-boundary in regex. Not to be confused with backspace.

• re.search() returns None if it doesn't find anything, which is always falsy.

• re.search() returns a Match object if it finds anything, which is always truthy.

• a group is what matched inside parentheses

• group numbering starts at 1

I have created a function to perform this action, place it on your ~/.vimrc.

fun! CopyBufferToClipboard()
    %y+
endfun
nnoremap <Leader>y :call CopyBufferToClipboard()<CR>
command! -nargs=0 CopyFile :call CopyBufferToClipboard()

OBS: If you are using neovim you also need some clipboard manager like xclip. for more information type in neovim :h checkhealth

It is also important to mention that not always a simple y will copy to the clipboard, in order to make every copy feed + wich is "Clipboard Register" try to set: :set clipboard=unnamed,unnamedplus. For mor information see: :h unnamed.

If anyone is running into the default value occasionally being not populated on the page in Chrome, IE 10/11, Firefox -- try adding this attribute to your input/select field checking for the populated variable in the HTML, like so:

<input data-ng-model="vm.x" data-ng-if="vm.x !== '' && vm.x !== undefined && vm.x !== null" />

function extractKeyValue(obj, value) {
    return Object.keys(obj)[Object.values(obj).indexOf(value)];
}

Made for closure compiler to extract key name which will be unknown after compilation

More sexy version but using future Object.entries function

function objectKeyByValue (obj, val) {
  return Object.entries(obj).find(i => i[1] === val);
}

You can do this with jQuery. Using their selectors, you can select by attributes, such as type. This does, however, require that your users have Javascript turned on, and an additional file to download, but if it works...

Based on the other answers, I looked into XmlTextWriter and came up with the following helper method:

static public string Beautify(this XmlDocument doc)
{
    StringBuilder sb = new StringBuilder();
    XmlWriterSettings settings = new XmlWriterSettings
    {
        Indent = true,
        IndentChars = "  ",
        NewLineChars = "\r\n",
        NewLineHandling = NewLineHandling.Replace
    };
    using (XmlWriter writer = XmlWriter.Create(sb, settings)) {
        doc.Save(writer);
    }
    return sb.ToString();
}

It's a bit more code than I hoped for, but it works just peachy.

Simple condition:

if any(str(elem) in ['a','b'] for elem in df['column'].tolist()):

• For XHTML, <input type="text" disabled="disabled" /> is the valid markup.
• For HTML5, <input type="text" disabled /> is valid and used by W3C on their samples.
• In fact, both ways works on all major browsers.

Make sure "Use: Regular expressions" is selected in the Find and Replace dialog:

Note that for Visual Studio 2010, this doesn't work in the Visual Studio Productivity Power Tools' "Quick Find" extension (as of the July 2011 update); instead, you'll need to use the full Find and Replace dialog (use Ctrl+Shift+H, or Edit --> Find and Replace --> Replace in Files), and change the scope to "Current Document".

Given just the pointer, you can't. You'll have to keep hold of the length you passed to new[] or, better, use std::vector to both keep track of the length, and release the memory when you've finished with it.

Yes, you will likely need to add another jar or dependency

javax.persistence.* is part of the Java Persistence API (JPA). It is only an API, you can think of it as similar to an interface. There are many implementations of JPA and this answer gives a very good elaboration of each, as well as which to use.

If your javax.persistence.* import cannot be resolved, you will need to provide the jar that implements JPA. You can do that either by manually downloading it (and adding it to your project) or by adding a declaration to a dependency management tool (for eg, Ivy/Maven/Gradle). See here for the EclipseLink implementation (the reference implementation) on Maven repo.

After doing that, your imports should be resolved.

Also see here for what is JPA about. The xml you are referring to could be persistence.xml, which is explained on page 3 of the link.

That being said, you might just be pointing to the wrong target runtime

If i recall correctly, you don't need to provide a JPA implementation if you are deploying it into a JavaEE app server like JBoss. See here "Note that you typically don't need it when you deploy your application in a Java EE 6 application server (like JBoss AS 6 for example).". Try changing your project's target runtime.

If your local project was setup to point to Tomcat while your remote repo assumes a JavaEE server, this could be the case. See here for the difference between Tomcat and JBoss.

Edit: I changed my project to point to GlassFish instead of Tomcat and javax.persistence.* resolved fine without any explicit JPA dependency.

• top level reference must be a more convenient name other that a..v... etc
• in o.v,o.i.e no need for the array [] because it is one json entry

for(n1 in yourjson)
    for(n1_1 in yourjson[n])
        for(n1_2 in yourjson[n][n1_1])
            obj[n1_2[name]] = n1_2[value];

for(n1 in yourobj){
    for(n1_1 in yourobj[n1]){
    for(n1_2 in yourobj[n1][n1_1]){

*You should use distinguish accessorizes when using [] method or dot notation

I agree with Quentin. It doesn't make sense as to why you want to do it like that. It's part of the Semantic Web concept. You have to plan out the objects of your web site for future integration/expansion. Another web app or web site cannot interact with your content if it doesn't follow the proper use-case.

IE and Firefox are two different beasts. There are a lot of things that IE allows that Firefox and other standards-aware browsers reject.

If you're trying to create buttons without actually submitting data then use a combination of DIV/CSS.

You've got the right idea, so here's how to go ahead: the onclick handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:

<script type="text/javascript">
function recp(id) {
  $('#myStyle').load('data.php?id=' + id);
}
</script>

<a href="#" onClick="recp('1')" > One   </a>
<a href="#" onClick="recp('2')" > Two   </a>
<a href="#" onClick="recp('3')" > Three </a>

<div id='myStyle'>
</div>

Then you put your PHP code into a separate file: (I've called it data.php in the above example)

<?php
  require ('myConnect.php');     
  $id = $_GET['id'];
  $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
  if( mysql_num_rows($results) > 0 )
  {
   $row = mysql_fetch_array( $results );
   echo $row['para'];
  }
?>

Use media queries. Your CSS code would be:

@media screen and (max-width: 1024px) {
    .yourClass {
        display: none !important;
    }
}

That's not the way to concat in MYSQL. Use the CONCAT function Have a look here: http://dev.mysql.com/doc/refman/4.1/en/string-functions.html#function_concat

Ah yes, that is how it is intended in SQL. You get the Max of every column seperately. It seems like you want to return values from the row with the max date, so you have to select the row with the max date. I prefer to do this with a subselect, as the queries keep compact easy to read.

SELECT TrainingID, CompletedDate, Notes
FROM HR_EmployeeTrainings ET 
WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID) 
AND CompletedDate in 
   (Select Max(CompletedDate) from HR_EmployeeTrainings B
    where B.TrainingID = ET.TrainingID)

If you also want to match by AntiRecID you should include that in the subselect as well.

As of SQL Server 2016 you have

DROP TABLE IF EXISTS [foo];

MSDN source

Try this:

X (\(Y\))? Z

Random character:

String.fromCharCode(i); //where is an int

Random int:

Math.floor(Math.random()*100);

Put it all together:

function randomNum(hi){
    return Math.floor(Math.random()*hi);
} 
function randomChar(){
    return String.fromCharCode(randomNum(100));
}
function randomString(length){
   var str = "";
   for(var i = 0; i < length; ++i){
        str += randomChar();
   }
   return str;
}
var RandomString = randomString(32); //32 length string

Right. So I've finally got to the bottom of the problem: it was a botched in-place OTA upgrade.

My suspicions intensified after my Garmin Fenix 2 wasn't able to connect via bluetooth and after googling "Marshmallow upgrade issues". Anyway, a "Factory reset" fixed the issue.

Surprisingly, the reset did not return the phone to the original Kitkat; instead, the wipe process picked up the OTA downloaded 6.0 upgrade package and ran with it, resulting (I guess) in a "cleaner" upgrade.

Of course, this meant that the phone lost all the apps that I'd installed. But, freshly installed apps, including mine, work without any changes (i.e. there is backward compatibility). Whew!

Eventually I realised that the reason behind this was that my "window" for the plots was too small, and I had to make it bigger to "fit" all the plots inside!

REST is stateless and doesn’t maintain any states between the requests. Client cookies / headers are set to maintain the user state like authentication. Say Client username/password are validated by third part authentication mechanism – 2nd level OTP gerneation etc. Once user get authenticated – headers /cookies comes to rest service end point exposed and we can assume user as auth since user is coming with valid headers/cookies. Now certain info of user like IP is either maintained in the cache and after that if request is coming from same Ip (mac address) for listed resources User is allowed. And cache is maintained for some particular time which get invalidated once time lapses. So either cache can be used or DB entries can be used to persist info b/w the requests.

Besides global memory, threads also share a number of other attributes (i.e., these attributes are global to a process, rather than specific to a thread). These attributes include the following:

• process ID and parent process ID;
• process group ID and session ID;
• controlling terminal;
• process credentials (user and group IDs);
• open file descriptors;
• record locks created using fcntl();
• signal dispositions;
• file system–related information: umask, current working directory, and root directory;
• interval timers (setitimer()) and POSIX timers (timer_create());
• System V semaphore undo (semadj) values (Section 47.8);
• resource limits;
• CPU time consumed (as returned by times());
• resources consumed (as returned by getrusage()); and
• nice value (set by setpriority() and nice()).

Among the attributes that are distinct for each thread are the following:

• thread ID (Section 29.5);
• signal mask;
• thread-specific data (Section 31.3);
• alternate signal stack (sigaltstack());
• the errno variable;
• floating-point environment (see fenv(3));
• realtime scheduling policy and priority (Sections 35.2 and 35.3);
• CPU affinity (Linux-specific, described in Section 35.4);
• capabilities (Linux-specific, described in Chapter 39); and
• stack (local variables and function call linkage information).

You can get access to the environment variables in either the command line or in the registry.

Command Line

If you want a specific environment variable, then just type the name of it (e.g. PATH), followed by a >, and the filename to write to. The following will dump the PATH environment variable to a file named path.txt.

C:\> PATH > path.txt

Registry Method

The Windows Registry holds all the environment variables, in different places depending on which set you are after. You can use the registry Import/Export commands to shift them into the other PC.

For System Variables:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

For User Variables:

HKEY_CURRENT_USER\Environment

The replace function should work for you.

REPLACE(str,from_str,to_str)

Returns the string str with all occurrences of the string from_str replaced by the string to_str. REPLACE() performs a case-sensitive match when searching for from_str.

Sass ignores curly brackets and semicolons and lay on nesting, which I found more useful.

You have to add a shebang. A shebang is the first line of the file. Its what the system is looking for in order to execute a file.

It should look like that :

#!/usr/bin/env python

or the real path

#!/usr/bin/python

You should also check the file have the right to be execute. chmod +x file.py

As Fabian said, take a look to Wikipedia : Wikipedia - Shebang (en)

There is a way to do this without explicitly setting your SHELL variable to point to bash. This can be useful if you have many makefiles since SHELL isn't inherited by subsequent makefiles or taken from the environment. You also need to be sure that anyone who compiles your code configures their system this way.

If you run sudo dpkg-reconfigure dash and answer 'no' to the prompt, your system will not use dash as the default shell. It will then point to bash (at least in Ubuntu). Note that using dash as your system shell is a bit more efficient though.

Think of it like this, every time you see a arrow, you replace it with function.
function parameters are defined before the arrow.
So in your example:

field => // function(field){}
e => { e.preventDefault(); } // function(e){e.preventDefault();}

and then together:

function (field) { 
    return function (e) { 
        e.preventDefault(); 
    };
}

From the docs:

// Basic syntax:
(param1, param2, paramN) => { statements }
(param1, param2, paramN) => expression
   // equivalent to:  => { return expression; }

// Parentheses are optional when there's only one argument:
singleParam => { statements }
singleParam => expression

I did a lot of reading from Excel files in C# a while ago, and we used two approaches:

• The COM API, where you access Excel's objects directly and manipulate them through methods and properties
• The ODBC driver that allows to use Excel like a database.

The latter approach was much faster: reading a big table with 20 columns and 200 lines would take 30 seconds via COM, and half a second via ODBC. So I would recommend the database approach if all you need is the data.

You need a With statement prior to this. Or make the .Cells into Cells

If you're on Windows:

Go to your php.ini file and remove the ; mark from the beginning of the following line:

;extension=php_curl.dll

After you have saved the file you must restart your HTTP server software (e.g. Apache) before this can take effect.

For Ubuntu 13.0 and above, simply use the debundled package. In a terminal type the following to install it and do not forgot to restart server.

sudo apt-get install php-curl

Or if you're using the old PHP5

sudo apt-get install php5-curl

or

sudo apt-get install php5.6-curl

Then restart apache to activate the package with

sudo service apache2 restart

You could make any sort algorithm slower by running your "is it sorted" step randomly. Something like:

1. Create an array of booleans the same size as the array you're sorting. Set them all to false.
2. Run an iteration of bogosort
3. Pick two random elements.
4. If the two elements are sorted in relation to eachother (i < j && array[i] < array[j]), mark the indexes of both on the boolean array to true. Overwise, start over.
5. Check if all of the booleans in the array are true. If not, go back to 3.
6. Done.

From crtdbg.h (and many other headers):

#ifndef NULL
#ifdef __cplusplus
#define NULL    0
#else
#define NULL    ((void *)0)

Therefore NULL is 0, at least on the Windows platform. So no, not that I know of.

Ok got this as:

                    {
                        grp.Key.MaterialID,
                        grp.Key.ProductID,
                        Quantity = grp.Sum(t => t.Quantity)
                    }).ToList();

Late contribution but just came across something similar in Python datetime and pandas give different timestamps for the same date.

If you have timezone-aware datetime in pandas, technically, tz_localize(None) changes the POSIX timestamp (that is used internally) as if the local time from the timestamp was UTC. Local in this context means local in the specified timezone. Ex:

import pandas as pd

t = pd.date_range(start="2013-05-18 12:00:00", periods=2, freq='H', tz="US/Central")
# DatetimeIndex(['2013-05-18 12:00:00-05:00', '2013-05-18 13:00:00-05:00'], dtype='datetime64[ns, US/Central]', freq='H')

t_loc = t.tz_localize(None)
# DatetimeIndex(['2013-05-18 12:00:00', '2013-05-18 13:00:00'], dtype='datetime64[ns]', freq='H')

# offset in seconds according to timezone:
(t_loc.values-t.values)//1e9
# array([-18000, -18000], dtype='timedelta64[ns]')

Note that this will leave you with strange things during DST transitions, e.g.

t = pd.date_range(start="2020-03-08 01:00:00", periods=2, freq='H', tz="US/Central")
(t.values[1]-t.values[0])//1e9
# numpy.timedelta64(3600,'ns')

t_loc = t.tz_localize(None)
(t_loc.values[1]-t_loc.values[0])//1e9
# numpy.timedelta64(7200,'ns')

In contrast, tz_convert(None) does not modify the internal timestamp, it just removes the tzinfo.

t_utc = t.tz_convert(None)
(t_utc.values-t.values)//1e9
# array([0, 0], dtype='timedelta64[ns]')

My bottom line would be: stick with timezone-aware datetime if you can or only use t.tz_convert(None) which doesn't modify the underlying POSIX timestamp. Just keep in mind that you're practically working with UTC then.

Infact this worked for me

Using CSS to vertical center, you can let the outer containers act like a table, and the content as a table cell. In this format your objects will stay centered. :)

I nested multiple objects in JSFiddle for an example, but the core idea is like this:

HTML

<div class="circle">
  <div class="content">
    Some text
  </div>
</div>

CSS

 .circle {
   /* act as a table so we can center vertically its child */
   display: table;
   /* set dimensions */
   height: 200px;
   width: 200px;
   /* horizontal center text */
   text-align: center;
   /* create a red circle */
   border-radius: 100%;
   background: red;
 }

 .content {
   /* act as a table cell */
   display: table-cell;
   /* and now we can vertically center! */
   vertical-align: middle;
   /* some basic markup */
   font-size: 30px;
   font-weight: bold;
   color: white;
 }

The multiple objects example:

HTML

<div class="container">
  <div class="content">

    <div class="centerhoriz">

      <div class="circle">
        <div class="content">
          Some text
        </div><!-- content -->
      </div><!-- circle -->

      <div class="square">
        <div class="content">

Parameter Expansion

The obvious answer is to use one of the special forms of parameter expansion:

: ${STATE?"Need to set STATE"}
: ${DEST:?"Need to set DEST non-empty"}

Or, better (see section on 'Position of double quotes' below):

: "${STATE?Need to set STATE}"
: "${DEST:?Need to set DEST non-empty}"

The first variant (using just ?) requires STATE to be set, but STATE="" (an empty string) is OK — not exactly what you want, but the alternative and older notation.

The second variant (using :?) requires DEST to be set and non-empty.

If you supply no message, the shell provides a default message.

The ${var?} construct is portable back to Version 7 UNIX and the Bourne Shell (1978 or thereabouts). The ${var:?} construct is slightly more recent: I think it was in System III UNIX circa 1981, but it may have been in PWB UNIX before that. It is therefore in the Korn Shell, and in the POSIX shells, including specifically Bash.

It is usually documented in the shell's man page in a section called Parameter Expansion. For example, the bash manual says:

${parameter:?word}

Display Error if Null or Unset. If parameter is null or unset, the expansion of word (or a message to that effect if word is not present) is written to the standard error and the shell, if it is not interactive, exits. Otherwise, the value of parameter is substituted.

The Colon Command

I should probably add that the colon command simply has its arguments evaluated and then succeeds. It is the original shell comment notation (before '#' to end of line). For a long time, Bourne shell scripts had a colon as the first character. The C Shell would read a script and use the first character to determine whether it was for the C Shell (a '#' hash) or the Bourne shell (a ':' colon). Then the kernel got in on the act and added support for '#!/path/to/program' and the Bourne shell got '#' comments, and the colon convention went by the wayside. But if you come across a script that starts with a colon, now you will know why.

Position of double quotes

blong asked in a comment:

Any thoughts on this discussion? https://github.com/koalaman/shellcheck/issues/380#issuecomment-145872749

The gist of the discussion is:

… However, when I shellcheck it (with version 0.4.1), I get this message:

In script.sh line 13:
: ${FOO:?"The environment variable 'FOO' must be set and non-empty"}
  ^-- SC2086: Double quote to prevent globbing and word splitting.

Any advice on what I should do in this case?

The short answer is "do as shellcheck suggests":

: "${STATE?Need to set STATE}"
: "${DEST:?Need to set DEST non-empty}"

To illustrate why, study the following. Note that the : command doesn't echo its arguments (but the shell does evaluate the arguments). We want to see the arguments, so the code below uses printf "%s\n" in place of :.

$ mkdir junk
$ cd junk
$ > abc
$ > def
$ > ghi
$ 
$ x="*"
$ printf "%s\n" ${x:?You must set x}    # Careless; not recommended
abc
def
ghi
$ unset x
$ printf "%s\n" ${x:?You must set x}    # Careless; not recommended
bash: x: You must set x
$ printf "%s\n" "${x:?You must set x}"  # Careful: should be used
bash: x: You must set x
$ x="*"
$ printf "%s\n" "${x:?You must set x}"  # Careful: should be used
*
$ printf "%s\n" ${x:?"You must set x"}  # Not quite careful enough
abc
def
ghi
$ x=
$ printf "%s\n" ${x:?"You must set x"}  # Not quite careful enough
bash: x: You must set x
$ unset x
$ printf "%s\n" ${x:?"You must set x"}  # Not quite careful enough
bash: x: You must set x
$ 

Note how the value in $x is expanded to first * and then a list of file names when the overall expression is not in double quotes. This is what shellcheck is recommending should be fixed. I have not verified that it doesn't object to the form where the expression is enclosed in double quotes, but it is a reasonable assumption that it would be OK.

The answers given above are good CRT answers, but if you want you can also use the Win32 solution to this. It's almost identical but IMO if you're programming for Windows you might as well just use its API (although I don't know if you are programming in Windows).

char* arrDayNames[7] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}; 
SYSTEMTIME st;
GetLocalTime(&st); // Alternatively use GetSystemTime for the UTC version of the time
printf("The current date and time are: %d/%d/%d %d:%d:%d:%d", st.wDay, st.wMonth, st.wYear, st.wHour, st.wMinute, st.wSecond, st.wMilliseconds);
printf("The day is: %s", arrDayNames[st.wDayOfWeek]);

Anyway, this is a Windows solution. I hope it will be helpful for you sometime!

The below code will convert the JSON array of the format

[{"version":"70.3.0;3"},{"version":"6R_16B000I_J4;3"},{"version":"46.3.0;3"},{"version":"20.3.0;2"},{"version":"4.1.3;0"},{"version":"10.3.0;1"}]

to List of String

[70.3.0;3, 6R_16B000I_J4;3, 46.3.0;3, 20.3.0;2, 4.1.3;0, 10.3.0;1]

Code :

ObjectMapper mapper = new ObjectMapper(); ArrayNode node = (ArrayNode)mapper.readTree(dataFromDb); data = node.findValuesAsText("version"); // "version" is the node in the JSON

and use com.fasterxml.jackson.databind.ObjectMapper

Expanding on Brian Camire's Answer:

Using =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) with CTRL+SHIFT+ENTER will include blank cells in the calculation. Blank cells will be evaluated as 0 which results in a lower median value. The same is true if using the average funtion. If you don't want to include blank cells in the calculation, use a nested if statement like so:

=MEDIAN(IF($A$1:$A$6="Airline",IF($B$1:$B$6<>"",$B$1:$B$6)))

Don't forget to press CTRL+SHIFT+ENTER to treat the formula as an "array formula".

I believe this is what you're looking for:

Convert Decimal Numbers to Text showing only the non-zero decimals

Especially this line might be helpful:

StringVar text     :=  Totext ( {Your.NumberField} , 6 , ""  )  ;

The first parameter is the decimal to be converted, the second parameter is the number of decimal places and the third parameter is the separator for thousands/millions etc.

As per the Newtonsoft Documentation you can also deserialize to an anonymous object like this:

var definition = new { Name = "" };

string json1 = @"{'Name':'James'}";
var customer1 = JsonConvert.DeserializeAnonymousType(json1, definition);

Console.WriteLine(customer1.Name);
// James

The is no API for adding a shortcut to the home screen in iOS, so no third-party browser is capable of providing that functionality.

If you must use a regexp (and really, you shouldn't!) this will work:

/^0\.00([1-8]\d*|90*)$/

should work, i.e.

• ^ nothing before,
• followed by 0.00 (nb: backslash escape for the . character)
• followed by 1 through 8, and any number of additional digits
• or 9, followed by any number of zeroes
• $: followed by nothing else

Update - new answer here: https://stackoverflow.com/a/19454282/411229. This answer only applies to those on Spring versions before 3.2.

I've looked for a while for a more definitive solution to this. This blog post seems to cover all my needs and doesn't rely on ordering of bean declarations. All credit to Mattias Severson. http://www.jayway.com/2011/11/30/spring-integration-tests-part-i-creating-mock-objects/

Basically, implement a FactoryBean

package com.jayway.springmock;

import org.mockito.Mockito;
import org.springframework.beans.factory.FactoryBean;

/**
 * A {@link FactoryBean} for creating mocked beans based on Mockito so that they 
 * can be {@link @Autowired} into Spring test configurations.
 *
 * @author Mattias Severson, Jayway
 *
 * @see FactoryBean
 * @see org.mockito.Mockito
 */
public class MockitoFactoryBean<T> implements FactoryBean<T> {

    private Class<T> classToBeMocked;

    /**
     * Creates a Mockito mock instance of the provided class.
     * @param classToBeMocked The class to be mocked.
     */
    public MockitoFactoryBean(Class<T> classToBeMocked) {
        this.classToBeMocked = classToBeMocked;
    }

    @Override
    public T getObject() throws Exception {
        return Mockito.mock(classToBeMocked);
    }

    @Override
    public Class<?> getObjectType() {
        return classToBeMocked;
    }

    @Override
    public boolean isSingleton() {
        return true;
    }
}

Next update your spring config with the following:

<beans...>
    <context:component-scan base-package="com.jayway.example"/>

    <bean id="someDependencyMock" class="com.jayway.springmock.MockitoFactoryBean">
        <constructor-arg name="classToBeMocked" value="com.jayway.example.SomeDependency" />
    </bean>
</beans>

I found this example also tricky. Why that in the 2nd loop at the last iteration nothing happens ($v stays 'two'), is that $v points to $a[3] (and vice versa), so it cannot assign value to itself, so it keeps the previous assigned value :)

There are many articles about writing code to import an excel file, but this is a manual/shortcut version:

If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.

The quickest way to get your Excel file into SQL is by using the import wizard:

1. Open SSMS (Sql Server Management Studio) and connect to the database where you want to import your file into.
2. Import Data: in SSMS in Object Explorer under 'Databases' right-click the destination database, select Tasks, Import Data. An import wizard will pop up (you can usually just click 'Next' on the first screen).

3. The next window is 'Choose a Data Source', select Excel:

   • In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).

   • Click the 'Browse' button to select the path to the Excel file you want to import.

   • Select the version of the excel file (97-2003 is usually fine for files with a .XLS extension, or use 2007 for newer files with a .XLSX extension)
   • Tick the 'First Row has headers' checkbox if your excel file contains headers.
   • Click next.

4. On the 'Choose a Destination' screen, select destination database:
   • Select the 'Server name', Authentication (typically your sql username & password) and select a Database as destination. Click Next.

5. On the 'Specify Table Copy or Query' window:

   • For simplicity just select 'Copy data from one or more tables or views', click Next.

6. 'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.

7. Click Finish.

The query can be written slightly simpler, like this:

DECLARE @T INT = 2 

SELECT CASE 
         WHEN @T < 1 THEN 'less than one' 
         WHEN @T = 1 THEN 'one' 
         ELSE 'greater than one' 
       END T

I put the IPython notebook in the same folder with the image. I use Windows. The image name is "phuong huong xac dinh.PNG".

In Markdown:

<img src="phuong huong xac dinh.PNG">

Code:

from IPython.display import Image
Image(filename='phuong huong xac dinh.PNG')

If you want to insert object, use this:

    currentLogs = [
 { socket_id: 'Server', message: 'Socketio online', data: 'Port  3333', logged: '2014-05-14 14:41:11' },
 { socket_id: 'Server', message: 'Waiting for Pi to connect...', data: 'Port: 8082', logged: '2014-05-14 14:41:11' }
];

console.warn(currentLogs.map(logs=>[ logs.socket_id , logs.message , logs.data , logs.logged ]));

The output will be:

[
  [ 'Server', 'Socketio online', 'Port  3333', '2014-05-14 14:41:11' ],
  [
    'Server',
    'Waiting for Pi to connect...',
    'Port: 8082',
    '2014-05-14 14:41:11'
  ]
]

Also, please check the documentation to know more about the map function.

We can handle the rejection at the individual promises level, so when we get the results in our result array, the array index which has been rejected will be undefined. We can handle that situation as needed, and use the remaining results.

Here I have rejected the first promise, so it comes as undefined, but we can use the result of the second promise, which is at index 1.

const manyPromises = Promise.all([func1(), func2()]).then(result => {_x000D_
    console.log(result[0]);  // undefined_x000D_
    console.log(result[1]);  // func2_x000D_
});_x000D_
_x000D_
function func1() {_x000D_
    return new Promise( (res, rej) => rej('func1')).catch(err => {_x000D_
        console.log('error handled', err);_x000D_
    });_x000D_
}_x000D_
_x000D_
function func2() {_x000D_
    return new Promise( (res, rej) => setTimeout(() => res('func2'), 500) );_x000D_
}

UTF-8 doesn't work for me in office 2007 without any service pack, with or without BOM (U+ffef or 0xEF,0xBB,0xBF , neither works) installing sp3 makes UTF-8 work when 0xEF,0xBB,0xBF BOM is prepended.

UTF-16 works when encoding in python using "utf-16-le" with a 0xff 0xef BOM prepended, and using tab as seperator. I had to manually write out the BOM, and then use "utf-16-le" rather then "utf-16", otherwise each encode() prepended the BOM to every row written out which appeared as garbage on the first column of the second line and after.

can't tell whether UTF-16 would work without any sp installed, since I can't go back now. sigh

This is on windows, dunno about office for MAC.

for both working cases, the import works when launching a download directly from the browser and the text import wizard doesn't intervence, it works like you would expect.

M.Ali's answer could be modified as

select Cast(Cast((37.0/38.0)*100 as decimal(18,2)) as varchar(5)) + ' %' as Percentage

Override all single element

$("*").css("cursor", "progress");

vector<vector<int>> board;
for(int i=0;i<m;i++) {
    board.push_back({});
    for(int j=0;j<n;j++) {
        board[i].push_back(0);
    }
}

This code snippet first inserts an empty vector at each turn, in the other nested loop it pushes the elements inside the vector created by the outer loop. Hope this solves the problem.

I needed to break some text into paragraphs ("p" tags), so I created a simple helper using some of the recommendations in previous answers (thank you guys).

public static MvcHtmlString ToParagraphs(this HtmlHelper html, string value) 
    { 
        value = html.Encode(value).Replace("\r", String.Empty);
        var arr = value.Split('\n').Where(a => a.Trim() != string.Empty);
        var htmlStr = "<p>" + String.Join("</p><p>", arr) + "</p>";
        return MvcHtmlString.Create(htmlStr);
    }

Usage:

@Html.ToParagraphs(Model.Comments)

Well, I've received this error today on Windows 8 64-bit out of the blue, for the first time, and it turns out my my.ini had been reset, and the bin/mysqld file had been deleted, among other items in the "Program Files/MySQL/MySQL Server 5.6" folder.

To fix it, I had to run the MySQL installer again, installing only the server, and copy a recent version of the my.ini file from "ProgramData/MySQL/MySQL Server 5.6", named my_2014-03-28T15-51-20.ini in my case (don't know how or why that got copied there so recently) back into "Program Files/MySQL/MySQL Server 5.6".

The only change to the system since MySQL worked was the installation of Native Instruments' Traktor 2 and a Traktor Audio 2 sound card, which really shouldn't have caused this problem, and no one else has used the system besides me. If anyone has a clue, it would be kind of you to comment to prevent this for me and anyone else who has encountered this.

you should not install react-scripts globally, for me this fixed the problem:

npm install --save react react-dom react-scripts

if this still dont work :

1. update to latest npm version : npm install -g npm@latest
2. delete node_modules directory
3. reinstall all dependencies : npm install

Add this line to your change event handler

    $("#theSelect option:selected").attr('disabled','disabled')
        .siblings().removeAttr('disabled');

This will disable the selected option, and enable any previously disabled options.

EDIT:

If you did not want to re-enable the previous ones, just remove this part of the line:

        .siblings().removeAttr('disabled');

EDIT:

http://jsfiddle.net/pd5Nk/1/

To re-enable when you click remove, add this to your click handler.

$("#theSelect option[value=" + value + "]").removeAttr('disabled');

android:drawablePadding is the easiest way to give padding to drawable icon but You can not give specific one side padding like paddingRight or paddingLeft of drawable icon.To achieve that you have to dig into it. And If you apply paddingLeft or paddingRight to Edittext then it will place padding to entire Edittext along with drawable icon.

This problem can occur if a class tries to get value of a non-existent key in web.config.

For example, the class has a static variable ClientID

private static string ClientID = System.Configuration.ConfigurationSettings.AppSettings["GoogleCalendarApplicationClientID"].ToString();

but the web.config doesn't contain the 'GoogleCalendarApplicationClientID' key, then the error will be thrown on any static function call or any class instance creation

React uses SyntheticKeyboardEvent to wrap native browser event and this Synthetic event provides named key attribute,
which you can use like this:

handleOnKeyDown = (e) => {
  if (['Enter', 'ArrowRight', 'Tab'].includes(e.key)) {
    // select item
    e.preventDefault();
  } else if (e.key === 'ArrowUp') {
    // go to top item
    e.preventDefault();
  } else if (e.key === 'ArrowDown') {
    // go to bottom item
    e.preventDefault();
  } else if (e.key === 'Escape') {
    // escape
    e.preventDefault();
  }
};

Here's what works for me, and is quickest and causes the least amount of pain / annoyance:

1) Paste you code snippet into sublime; make sure your syntax is looking good.

2) Right click and choose 'Copy as RTF'

3) Paste into your email

4) Done

= can be used when the subquery returns only 1 value.

When subquery returns more than 1 value, you will have to use IN:

select * 
from table
where id IN (multiple row query);

For example:

SELECT *
FROM Students
WHERE Marks = (SELECT MAX(Marks) FROM Students)   --Subquery returns only 1 value

SELECT *
FROM Students
WHERE Marks IN 
      (SELECT Marks 
       FROM Students 
       ORDER BY Marks DESC
       LIMIT 10)                       --Subquery returns 10 values

Date.parse recognizes only specific formats, and you don't have the option of telling it what your input format is. In this case it thinks that the input is in the format mm/dd/yyyy, so the result is wrong.

To fix this, you need either to parse the input yourself (e.g. with String.split) and then manually construct a Date object, or use a more full-featured library such as datejs.

Example for manual parsing:

var input = $('#' + controlName).val();
var parts = str.split("/");
var d1 = new Date(Number(parts[2]), Number(parts[1]) - 1, Number(parts[0]));

Example using date.js:

var input = $('#' + controlName).val();
var d1 = Date.parseExact(input, "d/M/yyyy");

encapsulate all of your js code within a window.onload function. I had a similar issue. Everything is loaded asynchronously in javascript so some parts load quicker than others, including your browser. Putting all of your code inside the onload function will ensure everything your code will need from the browser will be ready to use before attempting to execute.

Just install it from Android Studio ;)

You can have only one default export which you declare like:

export default App; or export default class App extends React.Component {...

and later do import App from './App'

If you want to export something more you can use named exports which you declare without default keyword like:

export {
  About,
  Contact,
}

or:

export About;
export Contact;

or:

export const About = class About extends React.Component {....
export const Contact = () => (<div> ... </div>);

and later you import them like:

import App, { About, Contact } from './App';

EDIT:

There is a mistake in the tutorial as it is not possible to make 3 default exports in the same main.js file. Other than that why export anything if it is no used outside the file?. Correct main.js :

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute  } from 'react-router'

class App extends React.Component {
...
}

class Home extends React.Component {
...
}


class About extends React.Component {
...
}


class Contact extends React.Component {
...
}


ReactDOM.render((
   <Router history = {browserHistory}>
      <Route path = "/" component = {App}>
         <IndexRoute component = {Home} />
         <Route path = "home" component = {Home} />
         <Route path = "about" component = {About} />
         <Route path = "contact" component = {Contact} />
      </Route>
   </Router>

), document.getElementById('app'))

EDIT2:

another thing is that this tutorial is based on react-router-V3 which has different api than v4.

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

The excerpt by Jeffrey Richter is very good. In short, add the library's as embedded resources and add a callback before anything else. Here is a version of the code (found in the comments of his page) that I put at the start of Main method for a console app (just make sure that any calls that use the library's are in a different method to Main).

AppDomain.CurrentDomain.AssemblyResolve += (sender, bargs) =>
        {
            String dllName = new AssemblyName(bargs.Name).Name + ".dll";
            var assem = Assembly.GetExecutingAssembly();
            String resourceName = assem.GetManifestResourceNames().FirstOrDefault(rn => rn.EndsWith(dllName));
            if (resourceName == null) return null; // Not found, maybe another handler will find it
            using (var stream = assem.GetManifestResourceStream(resourceName))
            {
                Byte[] assemblyData = new Byte[stream.Length];
                stream.Read(assemblyData, 0, assemblyData.Length);
                return Assembly.Load(assemblyData);
            }
        };

check your Bundle identifier for your project and you give Bundle identifier for your app which create on developer.facebook.com that they are same or not.

you can try this out if you want to pass more than one type of arguments, first add them all to an array of type Object and pass that object to RunWorkerAsync() here is an example :

   some_Method(){
   List<string> excludeList = new List<string>(); // list of strings
   string newPath ="some path";  // normal string
   Object[] args = {newPath,excludeList };
            backgroundAnalyzer.RunWorkerAsync(args);
      }

Now in the doWork method of background worker

backgroundAnalyzer_DoWork(object sender, DoWorkEventArgs e)
      {
        backgroundAnalyzer.ReportProgress(50);
        Object[] arg = e.Argument as Object[];
        string path= (string)arg[0];
        List<string> lst = (List<string>) arg[1];
        .......
        // do something......
        //.....
       }

IIS version 8.5 +

To enable Event Tracing for Windows for your website/application

1. Go to Logging and ensure either ETW event only or Both log file and ETW event ...is selected.

2. Enable the desired Recycle logs in the Advanced Settings for the Application Pool:

3. Go to the default Custom View: WebServer filters IIS logs:

Custom Views > ServerRoles > Web Server

4. ... or System logs:

Windows Logs > System

The question is trickier than it appears, because in many cases there isn't "an IP address for the local computer" so much as a number of different IP addresses. For example, the Mac I'm typing on right now (which is a pretty basic, standard Mac setup) has the following IP addresses associated with it:

fe80::1%lo0  
127.0.0.1 
::1 
fe80::21f:5bff:fe3f:1b36%en1 
10.0.0.138 
172.16.175.1
192.168.27.1

... and it's not just a matter of figuring out which of the above is "the real IP address", either... they are all "real" and useful; some more useful than others depending on what you are going to use the addresses for.

In my experience often the best way to get "an IP address" for your local computer is not to query the local computer at all, but rather to ask the computer your program is talking to what it sees your computer's IP address as. e.g. if you are writing a client program, send a message to the server asking the server to send back as data the IP address that your request came from. That way you will know what the relevant IP address is, given the context of the computer you are communicating with.

That said, that trick may not be appropriate for some purposes (e.g. when you're not communicating with a particular computer) so sometimes you just need to gather the list of all the IP addresses associated with your machine. The best way to do that under Unix/Mac (AFAIK) is by calling getifaddrs() and iterating over the results. Under Windows, try GetAdaptersAddresses() to get similar functionality. For example usages of both, see the GetNetworkInterfaceInfos() function in this file.

All string data must be UTF-8 encoded.

$out = array(
   'render' => utf8_encode($renderOutput), 
   'text' => utf8_encode($textOutput)
);

$out = json_encode($out);
die($out);

It can be as simple as:

default_data['item3'] = 3

As Chris' answer says, you can use update to add more than one item. An example:

default_data.update({'item4': 4, 'item5': 5})

Please see the documentation about dictionaries as data structures and dictionaries as built-in types.

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

Combining @Ramnath and @Tommy's answers allowed me to find an approach that works in base R for one or more columns.

Basic usage:

> df = data.frame(
+   id=1:3, foo=c('a|b','b|c','c|d'), 
+   bar=c('p|q', 'r|s', 's|t'), stringsAsFactors=F)
> transform(df, test=do.call(rbind, strsplit(foo, '|', fixed=TRUE)), stringsAsFactors=F)
  id foo bar test.1 test.2
1  1 a|b p|q      a      b
2  2 b|c r|s      b      c
3  3 c|d s|t      c      d

Multiple columns:

> transform(df, lapply(list(foo,bar),
+ function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar X1 X2 X1.1 X2.1
1  1 a|b p|q  a  b    p    q
2  2 b|c r|s  b  c    r    s
3  3 c|d s|t  c  d    s    t

Better naming of multiple split columns:

> transform(df, lapply({l<-list(foo,bar);names(l)=c('foo','bar');l}, 
+                          function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar foo.1 foo.2 bar.1 bar.2
1  1 a|b p|q     a     b     p     q
2  2 b|c r|s     b     c     r     s
3  3 c|d s|t     c     d     s     t

I'm a few years late, but why not this?

As most people have said, both ways work indeed, but I think only the first one should. Being semantically strict, the label does not "contain" the input. In my opinion, containment (parent/child) relationship in the markup structure should reflect containment in the visual output. i.e., an element surrounding another one in the markup should be drawn around that one in the browser. According to this, the label should be the input's sibling, not it's parent. So option number two is arbitrary and confusing. Everyone that has read the Zen of Python will probably agree (Flat is better than nested, Sparse is better than dense, There should be one-- and preferably only one --obvious way to do it...).

Because of decisions like that from W3C and major browser vendors (allowing "whichever way you prefer to do it", instead of "do it the right way") is that the web is so messed up today and we developers have to deal with tangled and so diverse legacy code.

I know question is already answered.

But let me add one point here. This is not only case of true or false. See below:

var val="Do";

Var c= (val == "Do" || val == "Done")
          ? 7
          : 0

Here if val is Do or Done then c will be 7 else it will be zero. In this case c will be 7.

This is actually another perspective of this operator.

Sorry for misunderstanding, from what I understood you want your DIV to have three different colors with different heights. This is the output of my code:

,

If this is what you want try this code:

div {_x000D_
    height: 100px;_x000D_
    width:400px;_x000D_
    position: relative;_x000D_
}_x000D_
.c {_x000D_
    background: blue; /* Old browsers */_x000D_
}_x000D_
_x000D_
.c:after{_x000D_
    content: '';_x000D_
    position: absolute;_x000D_
    width:20%;_x000D_
    left:0;_x000D_
    height:110%;_x000D_
    background: yellow;_x000D_
}_x000D_
.c:before{_x000D_
    content: '';_x000D_
    position: absolute;_x000D_
    width:40%;_x000D_
    left:60%;_x000D_
    height:140%;_x000D_
    background: green;_x000D_
}

<div class="c"></div>

The examples to os.walk in the documentation show how to do this:

for root, dirs, filenames in os.walk(indir):
    for f in filenames:
        log = open(os.path.join(root, f),'r')

How did you expect the "open" function to know that the string "1" is supposed to mean "/home/des/test/1" (unless "/home/des/test" happens to be your current working directory)?

As you didn't give us very much information, I'm assuming the language you're writing the code in is C#. First of all: Prefer System.Collections.Generic.List over an ArrayList. Secondly: One way would be to loop through every item in the list and check whether it contains "How". Another way would be to use LINQ. Here's a quick example that filters out every item which doesn't contain "How":

var list = new List<string>();
list.AddRange(new string[] {
    "How are you?",
    "How you doing?",
    "Joe",
    "Mike", });

foreach (string str in list.Where(s => s.Contains("How")))
{
    Console.WriteLine(str);
}
Console.ReadLine();

Even if it looks like the module is installed, as far as Python is concerned it isn't since it throws that exception.

Try installing the module again using one of the installation methods shown in the XlsxWriter docs and look out for any installation errors.

If there are none then run a sample program like the following:

import xlsxwriter

workbook = xlsxwriter.Workbook('hello.xlsx')
worksheet = workbook.add_worksheet()

worksheet.write('A1', 'Hello world')

workbook.close()
