If you want to look at parameters and methods, as others have pointed out you may well use pprint or dir()

If you want to see the actual value of the contents, you can do

object.__dict__

-D, --dump-header <file>
       Write the protocol headers to the specified file.

       This  option  is handy to use when you want to store the headers
       that a HTTP site sends to you. Cookies from  the  headers  could
       then  be  read  in  a  second  curl  invocation by using the -b,
       --cookie option! The -c, --cookie-jar option is however a better
       way to store cookies.

and

-S, --show-error
       When used with -s, --silent, it makes curl show an error message if it fails.

and

-L/--location
      (HTTP/HTTPS) If the server reports that the requested page has moved to a different location (indicated with a Location: header and a 3XX response
      code), this option will make curl redo the request on the new place. If used together with -i/--include or -I/--head, headers from  all  requested
      pages  will  be  shown.  When authentication is used, curl only sends its credentials to the initial host. If a redirect takes curl to a different
      host, it won’t be able to intercept the user+password. See also --location-trusted on how to change this. You can limit the amount of redirects to
      follow by using the --max-redirs option.

      When curl follows a redirect and the request is not a plain GET (for example POST or PUT), it will do the following request with a GET if the HTTP
      response was 301, 302, or 303. If the response code was any other 3xx code, curl will re-send the following  request  using  the  same  unmodified
      method.

from the man page. so

curl -sSL -D - www.acooke.org -o /dev/null

follows redirects, dumps the headers to stdout and sends the data to /dev/null (that's a GET, not a POST, but you can do the same thing with a POST - just add whatever option you're already using for POSTing data)

note the - after the -D which indicates that the output "file" is stdout.

For C99 there is P99_DECLARE_ENUM in P99 that lets you simply declare enum like this:

P99_DECLARE_ENUM(color, red, green, blue);

and then use color_getname(A) to obtain a string with the color name.

jquery $() function always return non null value - mean elements matched you selector cretaria. If the element was not found it will return an empty array. So your code will look something like this -

if ($("#btext" + i).length){
        //alert($("#btext" + i).text());
    $("#btext" + i).text("Branch " + i);
}

This has been asked so many times so that a user with over 1000 points ask for this is some strange
But just to show just another way to do it:

echo "/some/random/file.csv:some string" | awk '{sub(/:.*/,x)}1'
/some/random/file.csv

As I just figured, in case you have a model fitted on multiple linear regression, the above mentioned solution won't work.

You have to create your line manually as a dataframe that contains predicted values for your original dataframe (in your case data).

It would look like this:

# read dataset
df = mtcars

# create multiple linear model
lm_fit <- lm(mpg ~ cyl + hp, data=df)
summary(lm_fit)

# save predictions of the model in the new data frame 
# together with variable you want to plot against
predicted_df <- data.frame(mpg_pred = predict(lm_fit, df), hp=df$hp)

# this is the predicted line of multiple linear regression
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_line(color='red',data = predicted_df, aes(x=mpg_pred, y=hp))

# this is predicted line comparing only chosen variables
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_smooth(method = "lm", se = FALSE)

John's answer is 99% correct. I found that (at least in my configuration), you have to open the Build settings inspector for the PROJECT. The build settings for the target do not contain "Code Signing Entitlements". Perhaps this doesn't make a difference if you have only one target in your project. But if you have multiple targets, you need to go to the project build settings. In any case, after doing what John said, my ad-hoc distribution build worked perfectly.

I know this is kind of an old question, but this works for the select2 version 4.0

 $('#select2-element').val('').trigger('change');

or

$('#select2-element').val('').trigger('change.select2'); 

if you have change events bound to it

I had a similar problem. I created a new repository, NOT IN THE DIRECTORY THAT I WANTED TO MAKE A REPOSITORY. I then copied the files created to the directory I wanted to make a repository. Then open an existing repository using the directory I just copied the files to.

NOTE: I did use github desktop to make and open exiting repository.

• May be you have found your solution but recently i found new library which allows you to create any many shape you want to set to the Image VIew.

  • Download the library from here
  • Define your Xml as :-
  • <com.makeramen.roundedimageview.RoundedImageView......... app:riv_corner_radius="Yourradiusdip"/>
  • And enjoy the coding.! this library i found is the best! thanks [I posted this answer later on but i recently used it and found it realy helpful]

I can see many good answers to the question, but I still would like to share this method, by using Git parameter as follows:

When building the pipeline you will be asked to choose the branch:

After that through the groovy code you could specify the branch you want to clone:

git branch:BRANCH[7..-1], url: 'https://github.com/YourName/YourRepo.git' , credentialsId: 'github' 

Note that I'm using a slice from 7 to the last character to shrink "origin/" and get the branch name.

Also in case you configured a webhooks trigger it still work and it will take the default branch you specified(master in our case).

I'm using simple while loop to calculate the between dates

var start = new Date("01/05/2017");
var end = new Date("06/30/2017");
var newend = end.setDate(end.getDate()+1);
end = new Date(newend);
while(start < end){
   console.log(new Date(start).getTime() / 1000); // unix timestamp format
   console.log(start); // ISO Date format          
   var newDate = start.setDate(start.getDate() + 1);
   start = new Date(newDate);
}

Answering my own question.

curl -X GET --basic --user username:password \
     https://www.example.com/mobile/resource

curl -X DELETE --basic --user username:password \
     https://www.example.com/mobile/resource

curl -X PUT --basic --user username:password -d 'param1_name=param1_value' \
     -d 'param2_name=param2_value' https://www.example.com/mobile/resource

POSTing a file and additional parameter

curl -X POST -F 'param_name=@/filepath/filename' \
     -F 'extra_param_name=extra_param_value' --basic --user username:password \
     https://www.example.com/mobile/resource

Since Angular 2 went to RC 0, /angular2/typings/browser.d.ts is no longer part of the Angular 2 distribution. The file can be installed separately.

From here: https://github.com/angular/angular/issues/8513 there are a few options. The one that worked for me was:

typings install es6-shim --ambient --save

// In your app.ts
/// <reference path="typings/browser.d.ts" />

Replace your draw line with

g.drawOval(X - r, Y - r, r, r)

This should make the top-left of your circle the right place to make the center be (X,Y), at least as long as the point (X - r,Y - r) has both components in range.

For recovering a deleted branch, First go through the reflog history,

git reflog -n 60

Where n refers to the last n commits. Then find the proper head and create a branch with that head.

git branch testbranch HEAD@{30}

If it's too late at night and your table is already innoDB and you still don't see the link, maybe is due to the fact that now it's placed above the structure of the table, like in the picture is shown

The content is put after the HTTP headers. The format of an HTTP POST is to have the HTTP headers, followed by a blank line, followed by the request body. The POST variables are stored as key-value pairs in the body.

You can see this in the raw content of an HTTP Post, shown below:

POST /path/script.cgi HTTP/1.0
From: [email protected]
User-Agent: HTTPTool/1.0
Content-Type: application/x-www-form-urlencoded
Content-Length: 32

home=Cosby&favorite+flavor=flies

You can see this using a tool like Fiddler, which you can use to watch the raw HTTP request and response payloads being sent across the wire.

Windows
1- Find: CTRL + F
2- Select-in: Alt + Enter

Now you can change all the selection in one shot like "seen-on-tv" ST homepage Spot.

Under Windows, you can use

C:>dir /b /s java.exe

to print the full path of each and every "java.exe" on your C: drive, regardless of whether they are on your PATH environment variable.

Another option is the CONCAT command:

SELECT CONCAT(MyTable.TextColumn, 'Text') FROM MyTable

The + character has a special meaning in a URL => it means whitespace - . If you want to use the literal + sign, you need to URL encode it to %2b:

body=Hi+there%2bHello+there

Here's an example of how you could properly generate URLs in .NET:

var uriBuilder = new UriBuilder("https://mail.google.com/mail");

var values = HttpUtility.ParseQueryString(string.Empty);
values["view"] = "cm";
values["tf"] = "0";
values["to"] = "[email protected]";
values["su"] = "some subject";
values["body"] = "Hi there+Hello there";

uriBuilder.Query = values.ToString();

Console.WriteLine(uriBuilder.ToString());

The result

https://mail.google.com:443/mail?view=cm&tf=0&to=someemail%40somedomain.com&su=some+subject&body=Hi+there%2bHello+there

Maybe I can still help somebody out who bumps into this question, because this is a very old issue.

I needed this as well and wrote a behavior to take care of this. So here is the behavior:

public class StretchMaxWidthBehavior : Behavior<FrameworkElement>
{        
    protected override void OnAttached()
    {
        base.OnAttached();
        ((FrameworkElement)this.AssociatedObject.Parent).SizeChanged += this.OnSizeChanged;
    }

    protected override void OnDetaching()
    {
        base.OnDetaching();
        ((FrameworkElement)this.AssociatedObject.Parent).SizeChanged -= this.OnSizeChanged;
    }

    private void OnSizeChanged(object sender, SizeChangedEventArgs e)
    {
        this.SetAlignments();
    }

    private void SetAlignments()
    {
        var slot = LayoutInformation.GetLayoutSlot(this.AssociatedObject);
        var newWidth = slot.Width;
        var newHeight = slot.Height;

        if (!double.IsInfinity(this.AssociatedObject.MaxWidth))
        {
            if (this.AssociatedObject.MaxWidth < newWidth)
            {
                this.AssociatedObject.HorizontalAlignment = HorizontalAlignment.Left;
                this.AssociatedObject.Width = this.AssociatedObject.MaxWidth;
            }
            else
            {
                this.AssociatedObject.HorizontalAlignment = HorizontalAlignment.Stretch;
                this.AssociatedObject.Width = double.NaN;
            }
        }

        if (!double.IsInfinity(this.AssociatedObject.MaxHeight))
        {
            if (this.AssociatedObject.MaxHeight < newHeight)
            {
                this.AssociatedObject.VerticalAlignment = VerticalAlignment.Top;
                this.AssociatedObject.Height = this.AssociatedObject.MaxHeight;
            }
            else
            {
                this.AssociatedObject.VerticalAlignment = VerticalAlignment.Stretch;
                this.AssociatedObject.Height = double.NaN;
            }
        }
    }
}

Then you can use it like so:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>

    <TextBlock Grid.Column="0" Text="Label" />
    <TextBox Grid.Column="1" MaxWidth="600">
          <i:Interaction.Behaviors>                       
               <cbh:StretchMaxWidthBehavior/>
          </i:Interaction.Behaviors>
    </TextBox>
</Grid>

And finally to forget to use the System.Windows.Interactivity namespace to use the behavior.

Shog9 is right that this doesn't make all that much sense to ask, since an object could be referred to by multiple variables. If you don't really care about that, and all you want is to find the name of one of the global variables that refers to that object, you could do the following hack:

function myClass() { 
  this.myName = function () { 
    // search through the global object for a name that resolves to this object
    for (var name in this.global) 
      if (this.global[name] == this) 
        return name 
  } 
}
// store the global object, which can be referred to as this at the top level, in a
// property on our prototype, so we can refer to it in our object's methods
myClass.prototype.global = this
// create a global variable referring to an object
var myVar = new myClass()
myVar.myName() // returns "myVar"

Note that this is an ugly hack, and should not be used in production code. If there is more than one variable referring to an object, you can't tell which one you'll get. It will only search the global variables, so it won't work if a variable is local to a function. In general, if you need to name something, you should pass the name in to the constructor when you create it.

edit: To respond to your clarification, if you need to be able to refer to something from an event handler, you shouldn't be referring to it by name, but instead add a function that refers to the object directly. Here's a quick example that I whipped up that shows something similar, I think, to what you're trying to do:

function myConstructor () {
  this.count = 0
  this.clickme = function () {
    this.count += 1
    alert(this.count)
  }

  var newDiv = document.createElement("div")
  var contents = document.createTextNode("Click me!")

  // This is the crucial part. We don't construct an onclick handler by creating a
  // string, but instead we pass in a function that does what we want. In order to
  // refer to the object, we can't use this directly (since that will refer to the 
  // div when running event handler), but we create an anonymous function with an 
  // argument and pass this in as that argument.
  newDiv.onclick = (function (obj) { 
    return function () {
      obj.clickme()
    }
  })(this)

  newDiv.appendChild(contents)
  document.getElementById("frobnozzle").appendChild(newDiv)

}
window.onload = function () {
  var myVar = new myConstructor()
}

Add a horizontal black line using this:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000000"
    android:layout_marginTop="10dp"/>

Copy the diff file to the root of your repository, and then do:

git apply yourcoworkers.diff

More information about the apply command is available on its man page.

By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch on the sender and then git am on the receiver, because it also transfers the authorship info and the commit message.

If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3 option of apply that tries to merge in the changes.

It also works with Unix pipe as follows:

git diff d892531 815a3b5 | git apply

For everybody who uses Rider you have to select your project>Right Click>Properties>Configurations Then select Debug and Release and check "Allow unsafe code" for both.

To disable the vertical scroll bar, just add overflow-y:hidden;.

Find more about it: overflow.

This answer might also be helpful, it leverages js reduce operator/method to remove duplicates from array.

const result = [1, 2, 2, 3, 3, 3, 3].reduce((x, y) => x.includes(y) ? x : [...x, y], []);_x000D_
_x000D_
console.log(result);

The easiest thing you can do is wrap the contents of the <li> in a <span> or equivalent then you can set the color independently.

Alternatively, you could make an image with the bullet color you want and set it with the list-style-image property.

I hope this works:

System.Configuration.Configuration config= ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

config.AppSettings.Settings["Yourkey"].Value = "YourValue";
config.Save(ConfigurationSaveMode.Modified);

Although the question is solved, sharing knowledge for clarification of the correct meaning of the error.

The error says that the parameter needed to the concerned breaking function is not in the required format i.e. string or Buffer

The solution is to change the parameter to string

breakingFunction(JSON.stringify(offendingParameter), ... other params...);

or buffer

breakingFunction(BSON.serialize(offendingParameter), ... other params...);

Note: This assumes that you will declare constants for row and column indexes named COLUMN_HEADING_ROW, FIRST_COL, and LAST_COL, and that _xlSheet is the name of the ExcelSheet (using Microsoft.Interop.Excel)

First, define the range:

var columnHeadingsRange = _xlSheet.Range[
    _xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
    _xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];

Then, set the background color of that range:

columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;

Finally, set the font color:

columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;

And here's the code combined:

var columnHeadingsRange = _xlSheet.Range[
    _xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
    _xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];

columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;

columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;

I think so.. it's possible to 'bind' custom events, like(from: http://docs.jquery.com/Events/bind#typedatafn):

 $("p").bind("myCustomEvent", function(e, myName, myValue){
      $(this).text(myName + ", hi there!");
      $("span").stop().css("opacity", 1)
               .text("myName = " + myName)
               .fadeIn(30).fadeOut(1000);
    });
    $("button").click(function () {
      $("p").trigger("myCustomEvent", [ "John" ]);
    });

You can't multiply string and float.instead of you try as below.it works fine

totalAmount = salesAmount * float(salesTax)

It may be the typo if you incorrectly wrote the placeholder word. In my case I misspelled it as placehoder and got the error like this: AttributeError: 'module' object has no attribute 'placehoder'

One way is to add it by yourself! How? By merging kwargs with a bunch of defaults. This won't be appropriate on all occasions, for example, if the keys are not known to you in advance. However, if they are, here is a simple example:

import sys

def myfunc(**kwargs):
    args = {'country':'England','town':'London',
            'currency':'Pound', 'language':'English'}

    diff = set(kwargs.keys()) - set(args.keys())
    if diff:
        print("Invalid args:",tuple(diff),file=sys.stderr)
        return

    args.update(kwargs)            
    print(args)

The defaults are set in the dictionary args, which includes all the keys we are expecting. We first check to see if there are any unexpected keys in kwargs. Then we update args with kwargs which will overwrite any new values that the user has set. We don't need to test if a key exists, we now use args as our argument dictionary and have no further need of kwargs.

About the version of Android SDK Build-tools, the answer is

By default, the Android SDK uses the most recent downloaded version of the Build Tools.

Source

In Eclipse, you can choose a specific version by using the sdk.buildtools property in the project.properties file.

There seems to be no official page explaining all the build tools. Here is what the Android team says about this.

The [build] tools, such as aidl, aapt, dexdump, and dx, are typically called by the Android build tools or Android Development Tools (ADT), so you rarely need to invoke these tools directly. As a general rule, you should rely on the build tools or the ADT plugin to call them as needed.

Source

Anyway, here is a synthesis of the differences between tools, platform-tools and build-tools:

• Android SDK Tools
  • Location: $ANDROID_HOME/tools
  • Main tools: ant scripts (to build your APKs) and ddms (for debugging)
• Android SDK Platform-tools
  • Location: $ANDROID_HOME/platform-tools
  • Main tool: adb (to manage the state of an emulator or an Android device)
• Android SDK Build-tools
  • Location: $ANDROID_HOME/build-tools/$VERSION/
  • Documentation
  • Main tools: aapt (to generate R.java and unaligned, unsigned APKs), dx (to convert Java bytecode to Dalvik bytecode), and zipalign (to optimize your APKs)

Do not use authorization instead of authentication. I should get whole access to service all clients with header. The working code is :

public class TokenAuthenticationHandler : AuthenticationHandler<TokenAuthenticationOptions> 
{
    public IServiceProvider ServiceProvider { get; set; }

    public TokenAuthenticationHandler (IOptionsMonitor<TokenAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock, IServiceProvider serviceProvider) 
        : base (options, logger, encoder, clock) 
    {
        ServiceProvider = serviceProvider;
    }

    protected override Task<AuthenticateResult> HandleAuthenticateAsync () 
    {
        var headers = Request.Headers;
        var token = "X-Auth-Token".GetHeaderOrCookieValue (Request);

        if (string.IsNullOrEmpty (token)) {
            return Task.FromResult (AuthenticateResult.Fail ("Token is null"));
        }           

        bool isValidToken = false; // check token here

        if (!isValidToken) {
            return Task.FromResult (AuthenticateResult.Fail ($"Balancer not authorize token : for token={token}"));
        }

        var claims = new [] { new Claim ("token", token) };
        var identity = new ClaimsIdentity (claims, nameof (TokenAuthenticationHandler));
        var ticket = new AuthenticationTicket (new ClaimsPrincipal (identity), this.Scheme.Name);
        return Task.FromResult (AuthenticateResult.Success (ticket));
    }
}

Startup.cs :

#region Authentication
services.AddAuthentication (o => {
    o.DefaultScheme = SchemesNamesConst.TokenAuthenticationDefaultScheme;
})
.AddScheme<TokenAuthenticationOptions, TokenAuthenticationHandler> (SchemesNamesConst.TokenAuthenticationDefaultScheme, o => { });
#endregion

And mycontroller.cs

[Authorize(AuthenticationSchemes = SchemesNamesConst.TokenAuthenticationDefaultScheme)]
public class MainController : BaseController
{ ... }

I can't find TokenAuthenticationOptions now, but it was empty. I found the same class PhoneNumberAuthenticationOptions :

public class PhoneNumberAuthenticationOptions : AuthenticationSchemeOptions
{
    public Regex PhoneMask { get; set; }// = new Regex("7\\d{10}");
}

You should define static class SchemesNamesConst. Something like:

public static class SchemesNamesConst
{
    public const string TokenAuthenticationDefaultScheme = "TokenAuthenticationScheme";
}

To avoid the Save prompt message, you have to insert those lines

Application.DisplayAlerts = False
ThisWorkbook.Save
Application.DisplayAlerts = True

After saving your work, you need to use this line to quit the Excel application

Application.Quit

Don't just simply put those line in Private Sub Workbook_Open() unless you got do a correct condition checking, else you may spoil your excel file.

For safety purpose, please create a module to run it. The following are the codes that i put:

Sub testSave()
Application.DisplayAlerts = False
ThisWorkbook.Save
Application.DisplayAlerts = True
Application.Quit
End Sub

Hope it help you solve the problem.

Do a import os and then use os.sep

you can use undocumented wm_concat function.

select col1, wm_concat(distinct col2) col2_list 
from tab1
group by col1;

this function returns clob column, if you want you can use dbms_lob.substr to convert clob to varchar2.

I feel like the simplest solution is sans javascript and simply putting the link in each cell (provided you don't have massive gullies between your cells or really think border lines). Have your css:

.tableClass td a{
   display: block;
}

and then add a link per cell:

<table class="tableClass">
    <tr>
        <td><a href="#link">Link name</a></td>
        <td><a href="#link">Link description</a></td>
        <td><a href="#link">Link somthing else</a></td>
    </tr>
</table>

boring but clean.

If it is exactly null (as opposed to not set):

db.states.find({"cities.name": null})

(but as javierfp points out, it also matches documents that have no cities array at all, I'm assuming that they do).

If it's the case that the property is not set:

db.states.find({"cities.name": {"$exists": false}})

I've tested the above with a collection created with these two inserts:

db.states.insert({"cities": [{name: "New York"}, {name: null}]})
db.states.insert({"cities": [{name: "Austin"}, {color: "blue"}]})

The first query finds the first state, the second query finds the second. If you want to find them both with one query you can make an $or query:

db.states.find({"$or": [
  {"cities.name": null}, 
  {"cities.name": {"$exists": false}}
]})

Using atexit, you can pause the program right when it exits. If an error/exception is the reason for the exit, it will pause after printing the stacktrace.

import atexit

# Python 2 should use `raw_input` instead of `input`
atexit.register(input, 'Press Enter to continue...')

In my program, I put the call to atexit.register in the except clause, so that it will only pause if something went wrong.

if __name__ == "__main__":
    try:
        something_that_may_fail()

    except:
        # Register the pause.
        import atexit
        atexit.register(input, 'Press Enter to continue...')

        raise # Reraise the exception.

Following query also can be used:

select * 
  from t23
 where trunc(start_date) between trunc(to_date('01/15/2010','mm/dd/yyyy')) and trunc(to_date('01/17/2010','mm/dd/yyyy'))

This solution worked for me. I needed to create urls for a REST client dynamically so I created this method, so you just have to pass the restURL like this

/customer/{0}/user/{1}/order

and add as many params as you need:

public String createURL (String restURL, Object ... params) {       
    return new MessageFormat(restURL).format(params);
}

You just have to call this method like this:

createURL("/customer/{0}/user/{1}/order", 123, 321);

The output

"/customer/123/user/321/order"

Building on Alex's answer, here is a more generic function:

applyToGivenRow = @(func, matrix) @(row) func(matrix(row, :));
newApplyToRows = @(func, matrix) arrayfun(applyToGivenRow(func, matrix), 1:size(matrix,1), 'UniformOutput', false)';
takeAll = @(x) reshape([x{:}], size(x{1},2), size(x,1))';
genericApplyToRows = @(func, matrix) takeAll(newApplyToRows(func, matrix));

Here is a comparison between the two functions:

>> % Example
myMx = [1 2 3; 4 5 6; 7 8 9];
myFunc = @(x) [mean(x), std(x), sum(x), length(x)];
>> genericApplyToRows(myFunc, myMx)

ans =

     2     1     6     3
     5     1    15     3
     8     1    24     3

>> applyToRows(myFunc, myMx)
??? Error using ==> arrayfun
Non-scalar in Uniform output, at index 1, output 1.
Set 'UniformOutput' to false.

Error in ==> @(func,matrix)arrayfun(applyToGivenRow(func,matrix),1:size(matrix,1))'

Of you want to do it in a single line you can use

$("input").trigger(jQuery.Event('keydown', { which: '1'.charCodeAt(0) }));

public class UserController : ApiController
{

   Database db = new Database();

   // construction
   public UserController()
   {
      // Add the following code
      // problem will be solved
      db.Configuration.ProxyCreationEnabled = false;
   }

   public IEnumerable<User> GetAll()
    {
            return db.Users.ToList();
    }
}

import Foundation
var string = NSString(data: NSData?, encoding: UInt)

If the Application.Current is null for example by unit test, you can try this:

 System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke( YOUR action )

I solved the problem by changing the compileSdkVersion in the Gradle.build file from 18 to 17.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 18
    }
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
}

Implementations of java.util.Set

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

Ruby's bundled JSON is capable of exhibiting a bit of magic on its own.

If you have a string containing JSON serialized data that you want to parse:

JSON[string_to_parse]

JSON will look at the parameter, see it's a String and try decoding it.

Similarly, if you have a hash or array you want serialized, use:

JSON[array_of_values]

Or:

JSON[hash_of_values]

And JSON will serialize it. You can also use the to_json method if you want to avoid the visual similarity of the [] method.

Here are some examples:

hash_of_values = {'foo' => 1, 'bar' => 2}
array_of_values = [hash_of_values]

JSON[hash_of_values] 
# => "{\"foo\":1,\"bar\":2}"

JSON[array_of_values] 
# => "[{\"foo\":1,\"bar\":2}]"

string_to_parse = array_of_values.to_json
JSON[string_to_parse]
# => [{"foo"=>1, "bar"=>2}]

If you root around in JSON you might notice it's a subset of YAML, and, actually the YAML parser is what's handling JSON. You can do this too:

require 'yaml'

YAML.load(string_to_parse)
# => [{"foo"=>1, "bar"=>2}]

If your app is parsing both YAML and JSON, you can let YAML handle both flavors of serialized data.

I had the same issue, this solved it for me:

ALTER TABLE `my_table` ROW_FORMAT=DYNAMIC;

From MYSQL Documentation:

The DYNAMIC row format maintains the efficiency of storing the entire row in the index node if it fits (as do the COMPACT and REDUNDANT formats), but this new format avoids the problem of filling B-tree nodes with a large number of data bytes of long columns. The DYNAMIC format is based on the idea that if a portion of a long data value is stored off-page, it is usually most efficient to store all of the value off-page. With DYNAMIC format, shorter columns are likely to remain in the B-tree node, minimizing the number of overflow pages needed for any given row.

Very informally:

A POD is a type (including classes) where the C++ compiler guarantees that there will be no "magic" going on in the structure: for example hidden pointers to vtables, offsets that get applied to the address when it is cast to other types (at least if the target's POD too), constructors, or destructors. Roughly speaking, a type is a POD when the only things in it are built-in types and combinations of them. The result is something that "acts like" a C type.

Less informally:

• int, char, wchar_t, bool, float, double are PODs, as are long/short and signed/unsigned versions of them.
• pointers (including pointer-to-function and pointer-to-member) are PODs,
• enums are PODs
• a const or volatile POD is a POD.
• a class, struct or union of PODs is a POD provided that all non-static data members are public, and it has no base class and no constructors, destructors, or virtual methods. Static members don't stop something being a POD under this rule. This rule has changed in C++11 and certain private members are allowed: Can a class with all private members be a POD class?
• Wikipedia is wrong to say that a POD cannot have members of type pointer-to-member. Or rather, it's correct for the C++98 wording, but TC1 made explicit that pointers-to-member are POD.

Formally (C++03 Standard):

3.9(10): "Arithmetic types (3.9.1), enumeration types, pointer types, and pointer to member types (3.9.2) and cv-qualified versions of these types (3.9.3) are collectively caller scalar types. Scalar types, POD-struct types, POD-union types (clause 9), arrays of such types and cv-qualified versions of these types (3.9.3) are collectively called POD types"

9(4): "A POD-struct is an aggregate class that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-define copy operator and no user-defined destructor. Similarly a POD-union is an aggregate union that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-define copy operator and no user-defined destructor.

8.5.1(1): "An aggregate is an array or class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10) and no virtual functions (10.3)."

Controller function

Each directive's controller function is called whenever a new related element is instantiated.

Officially, the controller function is where one:

• Defines controller logic (methods) that may be shared between controllers.
• Initiates scope variables.

Again, it is important to remember that if the directive involves an isolated scope, any properties within it that inherit from the parent scope are not yet available.

Do:

• Define controller logic
• Initiate scope variables

Do not:

• Inspect child elements (they may not be rendered yet, bound to scope, etc.).

NodeJS, at one point (I think it was v0.6.x) had ArrayBuffer support. I created a small library for base64 encoding and decoding here, but since updating to v0.7, the tests (on NodeJS) fail. I'm thinking of creating something that normalizes this, but till then, I suppose Node's native Buffer should be used.

It hides the intention of the code.

It's two single tilde operators, so it does a bitwise complement (bitwise not) twice. The operations take out each other, so the only remaining effect is the conversion that is done before the first operator is applied, i.e. converting the value to an integer number.

Some use it as a faster alternative to Math.floor, but the speed difference is not that dramatic, and in most cases it's just micro optimisation. Unless you have a piece of code that really needs to be optimised, you should use code that descibes what it does instead of code that uses a side effect of a non-operation.

Update 2011-08:

With optimisation of the JavaScript engine in browsers, the performance for operators and functions change. With current browsers, using ~~ instead of Math.floor is somewhat faster in some browsers, and not faster at all in some browsers. If you really need that extra bit of performance, you would need to write different optimised code for each browser.

See: tilde vs floor

One line after form InitializeComponent();

cbo_MyDropBox.Text = "Select a server...";

You only need it once right? All you need to do if a pick is mandatory is check if the box index != -1. Could anyone elaborate why the other answers jump through hoops to get this going?

The only thing I'm missing here is having just this initial text grayed out. If you really want that just use a label in front and turn it off once the index is changed.

A simplest way without without one taking into account of (internal) dependencies :

1. Open "Solution Explorer".
2. Click on "Show all files"
3. Expand "References"
4. You'll see one (or more) reference(s) with slightly different icon than the rest. Typically, it is with yellow box suggesting you to take a note of it. Just remove it.
5. Add the reference back and compile your code.
6. That's all.

In my case, there was a problem with MySQL reference. Somehow, I could list three versions of it under the list of all available references. I followed process 1 through 6 above and it worked for me.

Solution 1 (Elegant approach with great user experience)

HTML

<input id="inputID" class="uppercase" name="inputName" value="" />

CSS

.uppercase{
    text-transform: uppercase;
}

JS

$('#inputID').on('blur', function(){
    this.value = this.value.toUpperCase();
});

By using CSS text-transform: uppercase; you'll eliminate the animation of lower to uppercase as the user types into the field.

Use blur event to handle converting to uppercase. This happens behind the scene as CSS took care of the user's visually appealing masking.

Solution 2 (Great, but less elegant)

If you insist on using keyup, here it is...

$('#inputID').on('keyup', function(){
    var caretPos = this.selectionStart;
    this.value = this.value.toUpperCase();
    this.setSelectionRange(caretPos, caretPos);
});

User would notice the animation of lowercase to uppercase as they type into the field. It gets the job done.

Solution 3 (Just get the job done)

$('#inputID').on('keyup', function(){
    this.value = this.value.toUpperCase();
});

This method is most commonly suggested but I do not recommend.

The downside of this solution is you'll be annoying the user as the cursor's caret position keeps jumping to the end of the text after every key input. Unless you know your users will never encounter typos or they will always clear the text and retype every single time, this method works.

More recently, I have found that other factors will also cause this error. I had an AES.h, AES.cpp containing a AES class and it gave this same unhelpful error. Only when I renamed to Encryption.h, Encryption.cpp and Encryption as the class name did it suddenly start working. There were no other code changes.

Compile Time:

Things that are done at compile time incur (almost) no cost when the resulting program is run, but might incur a large cost when you build the program.

Run-Time:

More or less the exact opposite. Little cost when you build, more cost when the program is run.

From the other side; If something is done at compile time, it runs only on your machine and if something is run-time, it run on your users machine.

Relevance

An example of where this is important would be a unit carrying type. A compile time version (like Boost.Units or my version in D) ends up being just as fast as solving the problem with native floating point code while a run-time version ends up having to pack around information about the units that a value are in and perform checks in them along side every operation. On the other hand, the compile time versions requiter that the units of the values be known at compile time and can't deal with the case where they come from run-time input.

There are a plethora of ways in which this can be done. The problem is how to make R aware of the locations of the variables you wish to divide.

Assuming

d <- read.table(text = "263807.0    1582
196190.5    1016
586689.0    3479
")
names(d) <- c("min", "count2.freq")
> d
       min count2.freq
1 263807.0        1582
2 196190.5        1016
3 586689.0        3479

My preferred way

To add the desired division as a third variable I would use transform()

> d <- transform(d, new = min / count2.freq)
> d
       min count2.freq      new
1 263807.0        1582 166.7554
2 196190.5        1016 193.1009
3 586689.0        3479 168.6373

The basic R way

If doing this in a function (i.e. you are programming) then best to avoid the sugar shown above and index. In that case any of these would do what you want

## 1. via `[` and character indexes
d[, "new"] <- d[, "min"] / d[, "count2.freq"]

## 2. via `[` with numeric indices
d[, 3] <- d[, 1] / d[, 2]

## 3. via `$`
d$new <- d$min / d$count2.freq

All of these can be used at the prompt too, but which is easier to read:

d <- transform(d, new = min / count2.freq)

or

d$new <- d$min / d$count2.freq ## or any of the above examples

Hopefully you think like I do and the first version is better ;-)

The reason we don't use the syntactic sugar of tranform() et al when programming is because of how they do their evaluation (look for the named variables). At the top level (at the prompt, working interactively) transform() et al work just fine. But buried in function calls or within a call to one of the apply() family of functions they can and often do break.

Likewise, be careful using numeric indices (## 2. above); if you change the ordering of your data, you will select the wrong variables.

The preferred way if you don't need replacement

If you are just wanting to do the division (rather than insert the result back into the data frame, then use with(), which allows us to isolate the simple expression you wish to evaluate

> with(d, min / count2.freq)
[1] 166.7554 193.1009 168.6373

This is again much cleaner code than the equivalent

> d$min / d$count2.freq
[1] 166.7554 193.1009 168.6373

as it explicitly states that "using d, execute the code min / count2.freq. Your preference may be different to mine, so I have shown all options.

Using this function you can get Image Bitmap. Just pass image url

 public Bitmap getBitmapFromURL(String strURL) {
      try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
      } catch (IOException e) {
        e.printStackTrace();
        return null;
      }
 }

Can I check - do you mean a rectangular array ([,])or a jagged array ([][])?

It is quite easy to sort a jagged array; I have a discussion on that here. Obviously in this case the Comparison<T> would involve a column instead of sorting by ordinal - but very similar.

Sorting a rectangular array is trickier... I'd probably be tempted to copy the data out into either a rectangular array or a List<T[]>, and sort there, then copy back.

Here's an example using a jagged array:

static void Main()
{  // could just as easily be string...
    int[][] data = new int[][] { 
        new int[] {1,2,3}, 
        new int[] {2,3,4}, 
        new int[] {2,4,1} 
    }; 
    Sort<int>(data, 2); 
} 
private static void Sort<T>(T[][] data, int col) 
{ 
    Comparer<T> comparer = Comparer<T>.Default;
    Array.Sort<T[]>(data, (x,y) => comparer.Compare(x[col],y[col])); 
} 

For working with a rectangular array... well, here is some code to swap between the two on the fly...

static T[][] ToJagged<T>(this T[,] array) {

Your Code

Replace it By

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')

This function works to arrays and objects. obs: it works like array_column php function. It means that an optional third parameter can be passed to define what column will correspond to the indices of return.

function array_column(list, column, indice){
    var result;

    if(typeof indice != "undefined"){
        result = {};

        for(key in list)
            result[list[key][indice]] = list[key][column];
    }else{
        result = [];

        for(key in list)
            result.push( list[key][column] );
    }

    return result;
}

This is a conditional version:

function array_column_conditional(list, column, indice){
    var result;

    if(typeof indice != "undefined"){
        result = {};

        for(key in list)
            if(typeof list[key][column] !== 'undefined' && typeof list[key][indice] !== 'undefined')
                result[list[key][indice]] = list[key][column];
    }else{
        result = [];

        for(key in list)
            if(typeof list[key][column] !== 'undefined')
                result.push( list[key][column] );
    }

    return result;
}

usability:

var lista = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];

var obj_list = [
  {a: 1, b: 2, c: 3},
  {a: 4, b: 5, c: 6},
  {a: 8, c: 9}
];

var objeto = {
  d: {a: 1, b: 3},
  e: {a: 4, b: 5, c: 6},
  f: {a: 7, b: 8, c: 9}
};

var list_obj = {
  d: [1, 2, 3],
  e: [4, 5],
  f: [7, 8, 9]
};

console.log( "column list: ", array_column(lista, 1) );
console.log( "column obj_list: ", array_column(obj_list, 'b', 'c') );
console.log( "column objeto: ", array_column(objeto, 'c') );
console.log( "column list_obj: ", array_column(list_obj, 0, 0) );

console.log( "column list conditional: ", array_column_conditional(lista, 1) );
console.log( "column obj_list conditional: ", array_column_conditional(obj_list, 'b', 'c') );
console.log( "column objeto conditional: ", array_column_conditional(objeto, 'c') );
console.log( "column list_obj conditional: ", array_column_conditional(list_obj, 0, 0) );

Output:

/*
column list:  Array [ 2, 5, 8 ]
column obj_list:  Object { 3: 2, 6: 5, 9: undefined }
column objeto:  Array [ undefined, 6, 9 ]
column list_obj:  Object { 1: 1, 4: 4, 7: 7 }

column list conditional:  Array [ 2, 5, 8 ]
column obj_list conditional:  Object { 3: 2, 6: 5 }
column objeto conditional:  Array [ 6, 9 ]
column list_obj conditional:  Object { 1: 1, 4: 4, 7: 7 }
*/

I think it needs to be checked if any row is selected or not? The below code would check it:

var entityGrid = $("#EntitesGrid").data("kendoGrid");
            var selectedItem = entityGrid.dataItem(entityGrid.select());
            if (selectedItem != undefined)
                alert("The Row Is SELECTED");
            else
                alert("NO Row Is SELECTED")

DateTime is not standard nullable type. If you want assign null to DateTime type of variable, you have to use DateTime? type which supports null value.

If you only want test your variable to be set (e.g. variable holds other than default value), you can use keyword "default" like in following code:

if (dateTimeVariable == default(DateTime))
{
    //do work for dateTimeVariable == null situation
}

If you provider does not support Invoke and you need to combine two expression, you can use an ExpressionVisitor to replace the parameter in the second expression by the parameter in the first expression.

class ParameterUpdateVisitor : ExpressionVisitor
{
    private ParameterExpression _oldParameter;
    private ParameterExpression _newParameter;

    public ParameterUpdateVisitor(ParameterExpression oldParameter, ParameterExpression newParameter)
    {
        _oldParameter = oldParameter;
        _newParameter = newParameter;
    }

    protected override Expression VisitParameter(ParameterExpression node)
    {
        if (object.ReferenceEquals(node, _oldParameter))
            return _newParameter;

        return base.VisitParameter(node);
    }
}

static Expression<Func<T, bool>> UpdateParameter<T>(
    Expression<Func<T, bool>> expr,
    ParameterExpression newParameter)
{
    var visitor = new ParameterUpdateVisitor(expr.Parameters[0], newParameter);
    var body = visitor.Visit(expr.Body);

    return Expression.Lambda<Func<T, bool>>(body, newParameter);
}

[TestMethod]
public void ExpressionText()
{
    string text = "test";

    Expression<Func<Coco, bool>> expr1 = p => p.Item1.Contains(text);
    Expression<Func<Coco, bool>> expr2 = q => q.Item2.Contains(text);
    Expression<Func<Coco, bool>> expr3 = UpdateParameter(expr2, expr1.Parameters[0]);

    var expr4 = Expression.Lambda<Func<Recording, bool>>(
        Expression.OrElse(expr1.Body, expr3.Body), expr1.Parameters[0]);

    var func = expr4.Compile();

    Assert.IsTrue(func(new Coco { Item1 = "caca", Item2 = "test pipi" }));
}

It's simple use:

long millis = new Date().getTime();

if you want it in particular format then you need Formatter like below

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String millisInString  = dateFormat.format(new Date());

Try this, just an example:

u.UserTypeOptions = new SelectList(new[]
    {
        new { ID="1", Name="name1" },
        new { ID="2", Name="name2" },
        new { ID="3", Name="name3" },
    }, "ID", "Name", 1);

Or

u.UserTypeOptions = new SelectList(new List<SelectListItem>
    {
        new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
        new SelectListItem { Selected = false, Text = "Homeowner", Value = "2"},
        new SelectListItem { Selected = false, Text = "Contractor", Value = "3"},
    },"Value","Text");

in terminal, type : conda list to obtain the packages installed using conda.

for the packages that pip recognizes, type : pip list

There may be some overlap of these lists as pip may recognize packages installed by conda (but maybe not the other way around, IDK).

There is a useful source here, including how to update or upgrade packages..

With other answers used, xs='auto' did a trick for me.

<Grid container
    alignItems='center'
    justify='center'
    style={{ minHeight: "100vh" }}>

    <Grid item xs='auto'>
        <GoogleLogin

            buttonText="Log in with Google"
            onSuccess={this.handleLogin}
            onFailure={this.handleLogin}
             cookiePolicy={'single_host_origin'}
         />
    </Grid>
</Grid>

Sorry for the external reference, but I think it is suited to your question:

C/C++ tip: How to detect the operating system type using compiler predefined macros

EDIT: After further investigation, my original assumption that this was an anomaly (bug?) of the declare @var datatype = value syntax is incorrect.

I modified your script for 2005 since that syntax is not supported, then tried the modified version on 2008. In 2005, I get the Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. error message. In 2008, the modified script is still successful.

declare @KMsg varchar(max); set @KMsg = REPLICATE('a',1024);
declare @MMsg varchar(max); set @MMsg = REPLICATE(@KMsg,1024);
declare @GMsg varchar(max); set @GMsg = REPLICATE(@MMsg,1024);
declare @GGMMsg varchar(max); set @GGMMsg = @GMsg + @GMsg + @MMsg;
select LEN(@GGMMsg)

It could be because of the property pageable -> pageSizes: true.

Remove this and check again.

So actually, my comment that you should do a console.log(el.nativeElement) should have pointed you in the right direction, but I didn't expect the output to be just a string representing the DOM Element.

What you have to do to inspect it in the way it helps you with your problem, is to do a console.log(el) in your example, then you'll have access to the nativeElement object and will see a property called innerHTML.

Which will lead to the answer to your original question:

let myCurrentContent:string = el.nativeElement.innerHTML; // get the content of your element
el.nativeElement.innerHTML = 'my new content'; // set content of your element

Update for better approach:

Since it's the accepted answer and web workers are getting more important day to day (and it's considered best practice anyway) I want to add this suggestion by Mark Rajcok here.

The best way to manipulate DOM Elements programmatically is using the Renderer:

constructor(private _elemRef: ElementRef, private _renderer: Renderer) { 
    this._renderer.setElementProperty(this._elemRef.nativeElement, 'innerHTML', 'my new content');
}

Edit

Since Renderer is deprecated now, use Renderer2 instead with setProperty

Update:

This question with its answer explained the console.log behavior.

Which means that console.dir(el.nativeElement) would be the more direct way of accessing the DOM Element as an "inspectable" Object in your console for this situation.

Hope this helped.

You can't access element like you did (document.frm_new_user_request). You have to use the function getElementById:

document.getElementById("frm_new_user_request")

So getting a value from an input could look like this:

var value = document.getElementById("frm_new_user_request").value

Also you can use some JavaScript framework, e.g. jQuery, which simplifies operations with DOM (Document Object Model) and also hides differences between various browsers from you.

Getting a value from an input using jQuery would look like this:

• input with ID "element": var value = $("#element).value
• input with class "element": var value = $(".element).value

Make sure those two types are nullable DateTime

var lastPostDate = reader[3] == DBNull.Value ?
                                        null : 
                                   (DateTime?) Convert.ToDateTime(reader[3]);

• Usage of DateTime? instead of Nullable<DateTime> is a time saver...
• Use better indent of the ? expression like I did.

I have found this excellent explanations in Eric Lippert blog:

The specification for the ?: operator states the following:

The second and third operands of the ?: operator control the type of the conditional expression. Let X and Y be the types of the second and third operands. Then,

• If X and Y are the same type, then this is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from X to Y, but not from Y to X, then Y is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from Y to X, but not from X to Y, then X is the type of the conditional expression.

• Otherwise, no expression type can be determined, and a compile-time error occurs.

The compiler doesn't check what is the type that can "hold" those two types.

In this case:

• null and DateTime aren't the same type.
• null doesn't have an implicit conversion to DateTime
• DateTime doesn't have an implicit conversion to null

So we end up with a compile-time error.

None of these answers alone worked for me. I had to combine them. (Maybe it is because I'm using a "button" tag and not a link typed as a button?)

In the HTML:

<div class="center-wrapper"><button type="submit" data-theme="b">Login</button></div>

In the CSS:

.center-wrapper {
    text-align: center;
    width: 300px;
    margin:0 auto;
    margin-left:auto;
    margin-right:auto;
    align:center;
    text-align:center;
}

Descendants will do exactly what you need, but be sure that you have included a namespace name together with element's name. If you omit it, you will probably get an empty list.

You can try this:

string[] arr = ((IEnumerable)obj).Cast<object>()
                                 .Select(x => x.ToString())
                                 .ToArray();

Once every array implements IEnumerable interface

The latest Java Web Start has been enhanced to allow good offline operation as well as allowing "local installation". It is worth looking into.

EDIT 2018: Java Web Start is no longer bundled with the newest JDK's. Oracle is pushing towards a "deploy your app locally with an enclosed JRE" model instead.

Here's the painful route:

    SSLContext ctx = null;
    try {
        KeyStore trustStore;
        trustStore = KeyStore.getInstance("JKS");
        trustStore.load(new FileInputStream("C:\\truststore_client"),
                "asdfgh".toCharArray());
        TrustManagerFactory tmf = TrustManagerFactory
                .getInstance("SunX509");
        tmf.init(trustStore);
        ctx = SSLContext.getInstance("SSL");
        ctx.init(null, tmf.getTrustManagers(), null);
    } catch (NoSuchAlgorithmException e1) {
        e1.printStackTrace();
    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (CertificateException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }
    ClientConfig config = new DefaultClientConfig();
    config.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
            new HTTPSProperties(null, ctx));

    WebResource service = Client.create(config).resource(
            "https://localhost:9999/");
    service.addFilter(new HTTPBasicAuthFilter(username, password));

    // Attempt to view the user's page.
    try {
        service.path("user/" + username).get(String.class);
    } catch (Exception e) {
        e.printStackTrace();
    }

Gotta love those six different caught exceptions :). There are certainly some refactoring to simplify the code a bit. But, I like delfuego's -D options on the VM. I wish there was a javax.net.ssl.trustStore static property that I could just set. Just two lines of code and done. Anyone know where that would be?

This may be too much to ask, but, ideally the keytool would not be used. Instead, the trustedStore would be created dynamically by the code and the cert is added at runtime.

There must be a better answer.

It's rather interesting to see how .NET get this internally to say the least... It's as "simple" as below:

namespace System.Threading
{
    using System;
    using System.Runtime.CompilerServices;

    internal static class PlatformHelper
    {
        private const int PROCESSOR_COUNT_REFRESH_INTERVAL_MS = 0x7530;
        private static volatile int s_lastProcessorCountRefreshTicks;
        private static volatile int s_processorCount;

        internal static bool IsSingleProcessor
        {
            get
            {
                return (ProcessorCount == 1);
            }
        }

        internal static int ProcessorCount
        {
            get
            {
                int tickCount = Environment.TickCount;
                int num2 = s_processorCount;
                if ((num2 == 0) || ((tickCount - s_lastProcessorCountRefreshTicks) >= 0x7530))
                {
                    s_processorCount = num2 = Environment.ProcessorCount;
                    s_lastProcessorCountRefreshTicks = tickCount;
                }
                return num2;
            }
        }
    }
}

If you read through any of the discussions on the android development group you will see that they discourage the use of anything that isn't in the public SDK because the rest is subject to extensive change.

You should try this

import java.util.Scanner;

public class Time_converter {

    public static void main(String[] args) {

        Scanner input = new Scanner (System.in);
        int seconds;
        int minutes ;
        int hours;
        System.out.print("Enter the number of seconds : ");
        seconds = input.nextInt();
        hours = seconds / 3600;
        minutes = (seconds%3600)/60;
        int seconds_output = (seconds% 3600)%60;


        System.out.println("The time entered in hours,minutes and seconds is:");
        System.out.println(hours  + " hours :" + minutes + " minutes:" + seconds_output +" seconds"); 
    }

}

Piping to xargs is a dirty way of doing that which can be done inside of find.

find . -type d -exec chmod 0755 {} \;
find . -type f -exec chmod 0644 {} \;

You can be even more controlling with other options, such as:

find . -type d -user harry -exec chown daisy {} \;

You can do some very cool things with find and you can do some very dangerous things too. Have a look at "man find", it's long but is worth a quick read. And, as always remember:

• If you are root it will succeed.
• If you are in root (/) you are going to have a bad day.
• Using /path/to/directory can make things a lot safer as you are clearly defining where you want find to run.

Try the following;

git config --global core.askpass "git-gui--askpass"

This will prompt for credentials and then "push" succeeds if credentials are correct.

My version using variables in a bash script:

Find any backslashes and replace with forward slashes:

input="This has a backslash \\"

output=$(echo "$input" | sed 's,\\,/,g')

echo "$output"

in oncreate method where you have set your Webview.

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.web_view);

web_view = (WebView) findViewById(R.id.web_view);
pd = new ProgressDialog(SiteOpenInWebView.this);
    pd.setMessage("Please wait Loading...");
    pd.show();
    web_view.setWebViewClient(new MyWebViewClient());
    web_view.loadUrl("ur site name");
 }

WebViewClient

private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    view.loadUrl(url);

    if (!pd.isShowing()) {
        pd.show();
    }

    return true;
}

@Override
public void onPageFinished(WebView view, String url) {
    System.out.println("on finish");
    if (pd.isShowing()) {
        pd.dismiss();
    }

  }
}

Pretty sure this solves what you're looking for:

HTML:

<table>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
</table>

Javascript (using jQuery):

$(document).ready(function(){
    $('.editbtn').click(function(){
        $(this).html($(this).html() == 'edit' ? 'modify' : 'edit');
    });
});

Edit:

Apparently I should have looked at your sample code first ;)

You need to change (at least) the ID attribute of each element. The ID is the unique identifier for each element on the page, meaning that if you have multiple items with the same ID, you'll get conflicts.

By using classes, you can apply the same logic to multiple elements without any conflicts.

JSFiddle sample

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

Maybe it is easier to convert the Date into the actual integer 20110506105524 and then convert this into a string:

function printDate() {
    var temp = new Date();
    var dateInt =
        ((((temp.getFullYear() * 100 + 
            temp.getMonth() + 1) * 100 + 
           temp.getDate()) * 100 +
          temp.getHours()) * 100 + 
         temp.getMinutes()) * 100 + 
        temp.getSeconds();

    debug ( '' + dateInt );  // convert to String
}

When temp.getFullYear() < 1000 the result will be one (or more) digits shorter.

Caution: this wont work with millisecond precision (i.e. 17 digits) since Number.MAX_SAFE_INTEGER is 9007199254740991 which is only 16 digits.

My guess is:

SELECT       LastName + ', ' + FirstName AS 'FullName'
FROM         customers
GROUP BY     LastName + ', ' + FirstName

Oracle has a similar limitation, which is annoying. I'm curious if there exists a better solution.

To answer the second half of the question, this limitation applies to more complex expressions such as your case statement as well. The best suggestion I've seen it to use a sub-select to name the complex expression.

For Angular 9.0 and above, update the "schematics":{} object in angular.json file like this:

"schematics": {
  "@schematics/angular:component": {
    "style": "scss"
  }
}

It seems that resource filtering/searching can be implemented in a RESTful way. The idea is to introduce a new endpoint called /filters/ or /api/filters/.

Using this endpoint filter can be considered as a resource and hence created via POST method. This way - of course - body can be used to carry all the parameters as well as complex search/filter structures can be created.

After creating such filter there are two possibilities to get the search/filter result.

1. A new resource with unique ID will be returned along with 201 Created status code. Then using this ID a GET request can be made to /api/users/ like:

   GET /api/users/?filterId=1234-abcd
   

2. After new filter is created via POST it won't reply with 201 Created but at once with 303 SeeOther along with Location header pointing to /api/users/?filterId=1234-abcd. This redirect will be automatically handled via underlying library.

In both scenarios two requests need to be made to get the filtered results - this may be considered as a drawback, especially for mobile applications. For mobile applications I'd use single POST call to /api/users/filter/.

How to keep created filters?

They can be stored in DB and used later on. They can also be stored in some temporary storage e.g. redis and have some TTL after which they will expire and will be removed.

What are the advantages of this idea?

Filters, filtered results are cacheable and can be even bookmarked.

Tomcat is just a servlet container, i.e. it implements only the servlets and JSP specification. Glassfish and JBoss are full Java EE servers (including stuff like EJB, JMS, ...), with Glassfish being the reference implementation of the latest Java EE 6 stack, but JBoss in 2010 was not fully supporting it yet.

Since these are member functions, call it as a member function on the instance, self.

def isNear(self, p):
    self.distToPoint(p)
    ...

You can also try dropping the index column if it is not needed to compare:

print(df1.reset_index(drop=True) == df2.reset_index(drop=True))

I have used this same technique in a unit test like so:

Since you are asking for space between , I would add an override to the last item to get rid of the extra margin there:

li {_x000D_
  background: red;_x000D_
  margin-bottom: 40px;_x000D_
}_x000D_
_x000D_
li:last-child {_x000D_
 margin-bottom: 0px;_x000D_
}_x000D_
_x000D_
ul {_x000D_
  background: silver;_x000D_
  padding: 1px;  _x000D_
  padding-left: 40px;_x000D_
}

<ul>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
<li>Item 1</li>_x000D_
</ul>

The result of it might not be visual at all times, because of margin-collapsing and stuff... in the example snippets I've included, I've added a small 1px padding to the ul-element to prevent the collapsing. Try removing the li:last-child-rule, and you'll see that the last item now extends the size of the ul-element.

The following should work and not require any permissions in the manifest (basically override shouldOverrideUrlLoading and handle links separately from tel, mailto, etc.):

    mWebView = (WebView) findViewById(R.id.web_view);

    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    mWebView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if( url.startsWith("http:") || url.startsWith("https:") ) {
                return false;
            }

            // Otherwise allow the OS to handle things like tel, mailto, etc.
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity( intent );
            return true;
        }
    });
    mWebView.loadUrl(url);

Also, note that in the above snippet I am enabling JavaScript, which you will also most likely want, but if for some reason you don't, just remove those 2 lines.

I have just been faced with the same challenge, but I thought "Why programming this in Python if you can solve it with a simple "grep"?, which led to the following Python code:

import subprocess
from subprocess import PIPE

try:
  output1, errors1 = subprocess.Popen(["c:\\cygwin\\bin\\grep", "-Fvf" ,"c:\\file1.txt", "c:\\file2.txt"], shell=True, stdout=PIPE, stderr=PIPE).communicate();
  output2, errors2 = subprocess.Popen(["c:\\cygwin\\bin\\grep", "-Fvf" ,"c:\\file2.txt", "c:\\file1.txt"], shell=True, stdout=PIPE, stderr=PIPE).communicate();
  if (len(output1) + len(output2) + len(errors1) + len(errors2) > 0):
    print ("Compare result : There are differences:");
    if (len(output1) + len(output2) > 0):
      print ("  Output differences : ");
      print (output1);
      print (output2);
    if (len(errors1) + len(errors2) > 0):
      print (" Errors : ");
      print (errors1);
      print (errors2);
  else:
    print ("Compare result : Both files are equal");
except Exception as ex:
  print("Compare result : Exception during comparison");
  print(ex);
  raise;

The trick behind this is the following: grep -Fvf file1.txt file2.txt verifies if all entries in file2.txt are present in file1.txt. By doing this in both directions we can see if the content of both files are "equal". I put "equal" between quotes because duplicate lines are disregarded in this way of working.

Obviously, this is just an example: you can replace grep by any commandline file comparison tool.

Try to use ES6 syntax of set timeout. Normal javascript setTimeout() won't work in react js

setTimeout(
      () => this.setState({ position: 100 }), 
      5000
    );

You need to specify an offset to addr2line, not a virtual address (VA). Presumably if you had address space randomization turned off, you could use a full VA, but in most modern OSes, address spaces are randomized for a new process.

Given the VA 0x4005BDC by valgrind, find the base address of your process or library in memory. Do this by examining the /proc/<PID>/maps file while your program is running. The line of interest is the text segment of your process, which is identifiable by the permissions r-xp and the name of your program or library.

Let's say that the base VA is 0x0x4005000. Then you would find the difference between the valgrind supplied VA and the base VA: 0xbdc. Then, supply that to add2line:

addr2line -e a.out -j .text 0xbdc

And see if that gets you your line number.

Movitz is a Lisp environment written in Common Lisp and running "on the metal". Unfortunately, some links on the Movitz main page deny access, but you can find instructions on how to download and compile the source code from the trac page. Also, a ready image can be found on the archive of this page.

IMHO this is utmost interesting, as it brings back the Lisp machine concept on the currently available hardware. It failed commercially, but this does not prove to me that the idea was bad.

The Unix haters handbook is a fun book that semi-seriously berates the concept of Unix and its derivatives. Many sections argument about how better the Lisp machine concept was.

Just to expand on the previous answer colorRampPalettecan handle more than two colors.

So for a more expanded "heat map" type look you can....

colfunc<-colorRampPalette(c("red","yellow","springgreen","royalblue"))
plot(rep(1,50),col=(colfunc(50)), pch=19,cex=2)

The resulting image:

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while period<12:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        if numpy.array_equal(tmp,universe_array) is True:
            break 
        period+=1

    return period

Do you have a local user.name or user.email that's overriding the global one?

git config --list --global | grep user
  user.name=YOUR NAME
  user.email=YOUR@EMAIL
git config --list --local | grep user
  user.name=YOUR NAME
  user.email=

If so, remove them

git config --unset --local user.name
git config --unset --local user.email

The local settings are per-clone, so you'll have to unset the local user.name and user.email for each of the repos on your machine.

It is printing the statement twice because it is printing it for both the parent and the child. The parent has a parent id of 0

Try something like this:

 pid_t  pid;
 pid = fork();
 if (pid == 0) 
    printf("This is the child process. My pid is %d and my parent's id is %d.\n", getpid(),getppid());
 else 
    printf("This is the parent process. My pid is %d and my parent's id is %d.\n", getpid(), getppid() );

A one-liner using the or operator:

($key = array_search($del_val, $messages)) !== false or unset($messages[$key]);

Dont use spaces:

SET @var="GREG"
::instead of SET @var = "GREG"
ECHO %@var%

That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.

Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

I needed that as well. I found that on msdn:

http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.activation.aspx

I think this delegate is for that.

On MacOS try using Numbers

If you have access to Mac OS I have found that the Apple spreadsheet Numbers does a good job of unpicking a complex multi-line CSV file that Excel could not handle. Just open the .csv with Numbers and then export to Excel.

follow he steps. in pgadmin

host-DataBase-Schemas- public (click right) CREATE script- open file -(choose xxx.sql) , then click over the option execute query write result to file -export data file ok- then click in save.its all. it work to me.

note: error in version command script enter image description herede sql over pgadmin can be search, example: http://www.forosdelweb.com/f21/campo-tipo-datetime-postgresql-245389/

This is the snippet to store environment variable and access it.

node {
   withEnv(["ENABLE_TESTS=true", "DISABLE_SQL=false"]) {
      stage('Select Jenkinsfile') {
          echo "Enable test?: ${env.DEVOPS_SKIP_TESTS}
          customStep script: this
      }
   }
}

Note: The value of environment variable is coming as a String. If you want to use it as a boolean then you have to parse it using Boolean.parse(env.DISABLE_SQL).

I really liked the answer of RichieHindle, however I liked the question as an exercise. Here's a brute force implementation using strings:)

import random
first = random.randint(1,9)
first = str(first)
n = 5

nrs = [str(random.randrange(10)) for i in range(n-1)]
for i in range(len(nrs))    :
    first += str(nrs[i])

print str(first)

If you'd like something a bit more readable, you can do this:

A = np.squeeze(np.asarray(M))

Equivalently, you could also do: A = np.asarray(M).reshape(-1), but that's a bit less easy to read.

The EclipsePasteAsJavaString plug-in allows you to insert text as a Java string by Ctrl + Shift + V

Example

Paste as usual via Ctrl+V:

some text with tabs and new lines

Paste as Java string via Ctrl+Shift+V

"some text\twith tabs\r\n" + "and new \r\n" + "lines"

You can use System.IO.Path.GetFileName to do this.

E.g.,

string[] files = Directory.GetFiles(dir);
foreach(string file in files)
    Console.WriteLine(Path.GetFileName(file));

While you could use FileInfo, it is much more heavyweight than the approach you are already using (just retrieving file paths). So I would suggest you stick with GetFiles unless you need the additional functionality of the FileInfo class.

Do you need to post the the form to an URL or do you only need to detect the submit-event? Because you can detect the submit-event by adding onsubmit="javascript:alert('I do also submit');"

<form action="javascript:alert('submitted');" method="post" id="testForm" onsubmit="javascript:alert('I do also submit');">...</form>

Not sure that this is what you are looking for though.

You should just do it with the raw URL of your file.

For example to download the README of AFNetworking:

curl https://raw.githubusercontent.com/AFNetworking/AFNetworking/master/README.md > ADREADME.md 

As it is a public repo you don't need any credentials. Please note the kind of url: raw.githubusercontent.com/path/to/file

The most concise solution I have found uses Sympy: https://www.geeksforgeeks.org/python-sympy-line-intersection-method/

# import sympy and Point, Line 
from sympy import Point, Line 
  
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(7, 7) 
l1 = Line(p1, p2) 
  
# using intersection() method 
showIntersection = l1.intersection(p3) 
  
print(showIntersection) 

You can use the wmic command:

wmic path CIM_LogicalDevice where "Description like 'USB%'" get /value

I checked and it worked for me.

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1" style="margin-top:100px;"><!--style with margin-top according to your need-->
        <ul class="nav navbar-nav navbar-right">
            <li><a href="#">About</a></li>
            <li><a href="#">Services</a></li>
            <li><a href="#">Contact</a></li>
        </ul>
    </div>

Another situation that is important to be aware of: The sort of default state for git is that you are working in the "master" branch. And for a lot of situations, you'll just hang out in that as your main working branch (although some people get fancy and do other things).

Anyway, that's just one branch. So a situation I might get into is:

My active branch is actually NOT the master branch. ... But I habitually do the command: git push (and I had previously done git push origin master, so it's a shortcut for THAT).

So I'm habitually pushing the master branch to the shared repo ... which is probably a good clean thing, in my case ...

But I have forgotten that the changes I have been working on are not yet IN the master branch !!!

So therefore everytime I try git push, and I see "Everything up to date", I want to scream, but of course, it is not git's fault! It's mine.

So instead, I merge my branch into master, and then do push, and everything is happy again.

You can explicitly format the query to produce a delimited string with something along the lines of:

select '"'||foo||'","'||bar||'"'
  from tab

And set up the output options as appropriate. As an option, the COLSEP variable on SQLPlus will let you produce delimited files without having to explicitly generate a string with the fields concatenated together. However, you will have to put quotes around strings on any columns that might contain embedded comma characters.

According to Pure CSS Scrollable Table with Fixed Header , I wrote a DEMO to easily fix the header by setting overflow:auto to the tbody.

table thead tr{
    display:block;
}

table th,table td{
    width:100px;//fixed width
}


table  tbody{
  display:block;
  height:200px;
  overflow:auto;//set tbody to auto
}

You need a click listener which calls addActivityItem if less than 2 options exist:

var activities = document.getElementById("activitySelector");

activities.addEventListener("click", function() {
    var options = activities.querySelectorAll("option");
    var count = options.length;
    if(typeof(count) === "undefined" || count < 2)
    {
        addActivityItem();
    }
});

activities.addEventListener("change", function() {
    if(activities.value == "addNew")
    {
        addActivityItem();
    }
});

function addActivityItem() {
    // ... Code to add item here
}

A live demo is here on JSfiddle.

I created a simplified version using Array.prototype.includes(). My technique is similar to @Kunle Babatunde.

const isVowel = (char) => ["a", "e", "i", "o", "u"].includes(char);_x000D_
_x000D_
console.log(isVowel("o"), isVowel("s"));

The party's pretty much dead now, but here's an "improved" version of user166390 that made its way into my extension library. Apart from some details, I added a delegate to calculate the merged value.

/// <summary>
/// Merges a dictionary against an array of other dictionaries.
/// </summary>
/// <typeparam name="TResult">The type of the resulting dictionary.</typeparam>

/// <param name="source">The source dictionary.</param>
/// <param name="mergeBehavior">A delegate returning the merged value. (Parameters in order: The current key, The current value, The previous value)</param>
/// <param name="mergers">Dictionaries to merge against.</param>
/// <returns>The merged dictionary.</returns>
public static TResult MergeLeft<TResult, TKey, TValue>(
    this TResult source,
    Func<TKey, TValue, TValue, TValue> mergeBehavior,
    params IDictionary<TKey, TValue>[] mergers)
    where TResult : IDictionary<TKey, TValue>, new()
{
    var result = new TResult();
    var sources = new List<IDictionary<TKey, TValue>> { source }
        .Concat(mergers);

    foreach (var kv in sources.SelectMany(src => src))
    {
        TValue previousValue;
        result.TryGetValue(kv.Key, out previousValue);
        result[kv.Key] = mergeBehavior(kv.Key, kv.Value, previousValue);
    }

    return result;
}

Do You have Internal Connection or External Connection. If you did Internal Connection then try this:

"Data Source=.\SQLEXPRESS;AttachDbFilename="Your PAth .mdf";Integrated Security=True;User Instance=True";

use the limit clausule, with the offset to choose the row number -1 so if u wanna get the number 8 row so use:

limit 1 offset 7

If you don't care about the order this should work:

Set<Direction> directions = EnumSet.allOf(Direction.class);
for(Direction direction : directions) {
    // do stuff
}

Extending the Dog, Cat example. The second method with ref changes the object referenced by the caller. Hence "Cat" !!!

    public static void Foo()
    {
        MyClass myObject = new MyClass();
        myObject.Name = "Dog";
        Bar(myObject);
        Console.WriteLine(myObject.Name); // Writes "Dog". 
        Bar(ref myObject);
        Console.WriteLine(myObject.Name); // Writes "Cat". 
    }

    public static void Bar(MyClass someObject)
    {
        MyClass myTempObject = new MyClass();
        myTempObject.Name = "Cat";
        someObject = myTempObject;
    }

    public static void Bar(ref MyClass someObject)
    {
        MyClass myTempObject = new MyClass();
        myTempObject.Name = "Cat";
        someObject = myTempObject;
    }

BehaviorSubject is a type of subject, a subject is a special type of observable so you can subscribe to messages like any other observable. The unique features of BehaviorSubject are:

• It needs an initial value as it must always return a value on subscription even if it hasn't received a next()
• Upon subscription, it returns the last value of the subject. A regular observable only triggers when it receives an onnext
• at any point, you can retrieve the last value of the subject in a non-observable code using the getValue() method.

Unique features of a subject compared to an observable are:

• It is an observer in addition to being an observable so you can also send values to a subject in addition to subscribing to it.

In addition, you can get an observable from behavior subject using the asObservable() method on BehaviorSubject.

Observable is a Generic, and BehaviorSubject is technically a sub-type of Observable because BehaviorSubject is an observable with specific qualities.

Example with BehaviorSubject:

// Behavior Subject

// a is an initial value. if there is a subscription 
// after this, it would get "a" value immediately
let bSubject = new BehaviorSubject("a"); 

bSubject.next("b");

bSubject.subscribe(value => {
  console.log("Subscription got", value); // Subscription got b, 
                                          // ^ This would not happen 
                                          // for a generic observable 
                                          // or generic subject by default
});

bSubject.next("c"); // Subscription got c
bSubject.next("d"); // Subscription got d

Example 2 with regular subject:

// Regular Subject

let subject = new Subject(); 

subject.next("b");

subject.subscribe(value => {
  console.log("Subscription got", value); // Subscription wont get 
                                          // anything at this point
});

subject.next("c"); // Subscription got c
subject.next("d"); // Subscription got d

An observable can be created from both Subject and BehaviorSubject using subject.asObservable().

The only difference being you can't send values to an observable using next() method.

In Angular services, I would use BehaviorSubject for a data service as an angular service often initializes before component and behavior subject ensures that the component consuming the service receives the last updated data even if there are no new updates since the component's subscription to this data.

This completed for me in 36 seconds on our DEV server. Like Brian's answer, focusing on filtering to the range is important from within the query; a BETWEEN still tries to generate all the initial records prior to the lower bound even though it doesn't need them.

declare @s bigint = 10000000
    ,   @e bigint = 20000000

;WITH 
Z AS (SELECT 0 z FROM (VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12),(13),(14),(15)) T(n)),
Y AS (SELECT 0 z FROM Z a, Z b, Z c, Z d, Z e, Z f, Z g, Z h, Z i, Z j, Z k, Z l, Z m, Z n, Z o, Z p),
N AS (SELECT ROW_NUMBER() OVER (PARTITION BY 0 ORDER BY z) n FROM Y)

SELECT TOP (1+@e-@s) @s + n - 1 FROM N

Note that ROW_NUMBER is a bigint, so we can't go over 2^^64 (==16^^16) generated records with any method that uses it. This query therefore respects the same upper limit on generated values.

A download link would be a link to the resource you want to download. It is constructed in the same way that any other link would be:

<a href="path to resource.name of file">Link</a>

<a href="files/installer.exe">Link to installer</a>

sudo apt-get install -y ngrok-client

For non-sealed classes simply inherit from them:

public class Vector : List<int> { }

But for sealed classes it's possible to simulate typedef behavior with such base class:

public abstract class Typedef<T, TDerived> where TDerived : Typedef<T, TDerived>, new()
{
    private T _value;

    public static implicit operator T(Typedef<T, TDerived> t)
    {
        return t == null ? default : t._value;
    }

    public static implicit operator Typedef<T, TDerived>(T t)
    {
        return t == null ? default : new TDerived { _value = t };
    }
}

// Usage examples

class CountryCode : Typedef<string, CountryCode> { }
class CurrencyCode : Typedef<string, CurrencyCode> { }
class Quantity : Typedef<int, Quantity> { }

void Main()
{
    var canadaCode = (CountryCode)"CA";
    var canadaCurrency = (CurrencyCode)"CAD";
    CountryCode cc = canadaCurrency;        // Compilation error
    Concole.WriteLine(canadaCode == "CA");  // true
    Concole.WriteLine(canadaCurrency);      // CAD

    var qty = (Quantity)123;
    Concole.WriteLine(qty);                 // 123
}

actually, I found this in the code of a php based cms.

redirect('?module=blog', 0);

so it is possible. In this case, you are logged in at the admin level, so no harm no foul (I suppose). the first part is the url, and the second? I can't find any documentation for what the integer is for, but I guess it's either time, or data since it is attached to a form.

I, too, wanted to refresh a page after an event, and placing this in a better spot worked out well.

It should be possible changing setting the JAVA_HOME environment variable differently for specific applications.

When starting from the command line or from a batch script you can use set JAVA_HOME=C:\...\j2dskXXX to change the JAVA_HOME environment.

It is possible that you also need to change the PATH environment variable to use the correct java binary. To do this you can use set PATH=%JAVA_HOME%\bin;%PATH%.

left: initial

This will also set left back to the browser default.

But important to know property: initial is not supported in IE.

Try this

Very close to what you posted, actually.

To get the assigned value, or default if it's missing:

FOO="${VARIABLE:-default}"  # If variable not set or null, use default.

Or to assign default to VARIABLE at the same time:

FOO="${VARIABLE:=default}"  # If variable not set or null, set it to default.

This worked for me, it works in firefox, ie and chrome.

    var content = "This is a test Message";

    var contentHtml = [
        '<div><b>',
        'TestReport',
        '<button style="float:right; margin-right:10px;"',
        'id="printButton" onclick="printDocument()">Print</button></div>',
        content
    ].join('');

    var printWindow = window.open();

    printWindow.document.write('<!DOCTYPE HTML><html><head<title>Reports</title>',
        '<script>function printDocument() {',
        'window.focus();',
        'window.print();',
        'window.close();',
        '}',
        '</script>');

    printWindow.document.write("stylesheet link here");

    printWindow.document.write('</head><body>');
    printWindow.document.write(contentHtml);
    printWindow.document.write('</body>');
    printWindow.document.write('</html>');
    printWindow.document.close();

I required having count(*) > 1 also. So, I wrote my own query after referring some the above queries

SYNTAX:

select sum(count) from (select count(`table_name`.`id`) as `count` from `table_name` where {some condition} group by {some_column} having count(`table_name`.`id`) > 1) as `tmp`;

Example:

select sum(count) from (select count(`table_name`.`id`) as `count` from `table_name` where `table_name`.`name` IS NOT NULL and `table_name`.`name` != '' group by `table_name`.`name` having count(`table_name`.`id`) > 1) as `tmp`;

This code works for me:

Dim script As String = "<script type=""text/javascript"">window.open('" & URL.ToString & "');</script>"
ClientScript.RegisterStartupScript(Me.GetType, "openWindow", script)

Hope this helps, and returns only number of tables in a database

Use database;

SELECT COUNT(*) FROM sys.tables;

The following illustrates the solution, assign your string to a variable pointer to a constant array of char (a string is a constant pointer to a constant array of char - plus length info):

#include <iostream>

void Swap(const char * & left, const char * & right) {
    const char *const temp = left;
    left = right;
    right = temp;
}

int main() {
    const char * x = "Hello"; // These works because you are making a variable
    const char * y = "World"; // pointer to a constant string
    std::cout << "x = " << x << ", y = " << y << '\n';
    Swap(x, y);
    std::cout << "x = " << x << ", y = " << y << '\n';
}

The quickest fix for me was doing the following:

cd /usr/local
git reset --hard FETCH_HEAD

Then I retried brew install imagemagick and it correctly pulled the package from the new mirror, instead of adamv.

If that does not work, ensure that /Library/Caches/Homebrew does not contain any imagemagick files or folders. Delete them if it does.

May be you need Decimal

>>> from decimal import Decimal    
>>> Decimal(2.675)
Decimal('2.67499999999999982236431605997495353221893310546875')

Floating Point Arithmetic

The following replaces variables of the form <<VAR>>, with values looked up from a Map. You can test it online here

For example, with the following input string

BMI=(<<Weight>>/(<<Height>>*<<Height>>)) * 70
Hi there <<Weight>> was here

and the following variable values

Weight, 42
Height, HEIGHT 51

outputs the following

BMI=(42/(HEIGHT 51*HEIGHT 51)) * 70

Hi there 42 was here

Here's the code

  static Pattern pattern = Pattern.compile("<<([a-z][a-z0-9]*)>>", Pattern.CASE_INSENSITIVE);

  public static String replaceVarsWithValues(String message, Map<String,String> varValues) {
    try {
      StringBuffer newStr = new StringBuffer(message);
      int lenDiff = 0;
      Matcher m = pattern.matcher(message);
      while (m.find()) {
        String fullText = m.group(0);
        String keyName = m.group(1);
        String newValue = varValues.get(keyName)+"";
        String replacementText = newValue;
        newStr = newStr.replace(m.start() - lenDiff, m.end() - lenDiff, replacementText);
        lenDiff += fullText.length() - replacementText.length();
      }
      return newStr.toString();
    } catch (Exception e) {
      return message;
    }
  }


  public static void main(String args[]) throws Exception {
      String testString = "BMI=(<<Weight>>/(<<Height>>*<<Height>>)) * 70\n\nHi there <<Weight>> was here";
      HashMap<String,String> values = new HashMap<>();
      values.put("Weight", "42");
      values.put("Height", "HEIGHT 51");
      System.out.println(replaceVarsWithValues(testString, values));
  }

and although not requested, you can use a similar approach to replace variables in a string with properties from your application.properties file, though this may already be being done:

private static Pattern patternMatchForProperties =
      Pattern.compile("[$][{]([.a-z0-9_]*)[}]", Pattern.CASE_INSENSITIVE);

protected String replaceVarsWithProperties(String message) {
    try {
      StringBuffer newStr = new StringBuffer(message);
      int lenDiff = 0;
      Matcher m = patternMatchForProperties.matcher(message);
      while (m.find()) {
        String fullText = m.group(0);
        String keyName = m.group(1);
        String newValue = System.getProperty(keyName);
        String replacementText = newValue;
        newStr = newStr.replace(m.start() - lenDiff, m.end() - lenDiff, replacementText);
        lenDiff += fullText.length() - replacementText.length();
      }
      return newStr.toString();
    } catch (Exception e) {
      return message;
    }
  }

I use Ubuntu linux, and in my case the error was caused by incorrect statement syntax (which I found out by typing perror 150 at the terminal, which gives

MySQL error code 150: Foreign key constraint is incorrectly formed

Changing the syntax of the query from

alter table scale add constraint foreign key (year_id) references year.id;

to

alter table scale add constraint foreign key (year_id) references year(id);

fixed it.

If your variable is used only within the context of a single function, you're better off using a stack variable, i.e., Option 2. As others have said, you do not have to manage the lifetime of stack variables - they are constructed and destructed automatically. Also, allocating/deallocating a variable on the heap is slow by comparison. If your function is called often enough, you'll see a tremendous performance improvement if use stack variables versus heap variables.

That said, there are a couple of obvious instances where stack variables are insufficient.

If the stack variable has a large memory footprint, then you run the risk of overflowing the stack. By default, the stack size of each thread is 1 MB on Windows. It is unlikely that you'll create a stack variable that is 1 MB in size, but you have to keep in mind that stack utilization is cumulative. If your function calls a function which calls another function which calls another function which..., the stack variables in all of these functions take up space on the same stack. Recursive functions can run into this problem quickly, depending on how deep the recursion is. If this is a problem, you can increase the size of the stack (not recommended) or allocate the variable on the heap using the new operator (recommended).

The other, more likely condition is that your variable needs to "live" beyond the scope of your function. In this case, you'd allocate the variable on the heap so that it can be reached outside the scope of any given function.

If you are using Angular you can get it off with:

"env": {
    "browser": true,
    "node": true
},
"rules" : {
    "angular/window-service": 0
 }

I don't think that functional languages will solve anything, and that this is just a hype that management is trying to sell, remember the only truth:

There is no silver bullet.

All the rest, is bullshit, also they've said that OO would solve our problems, that Web Services would solve our problems, that Xml would solve our problems, but in the end the above truth applied, and everything went down. Also, twenty years from now on, who says that we will be using binary computers at all? Why not quantic computers? No one can predict the future, at least not on this planet. (That is the second truth)

To see duplicate values:

with MYCTE  as (
    select row_number() over ( partition by name  order by name) rown, *
    from tmptest  
    ) 
select * from MYCTE where rown <=1

man page of strcat says that arg1 and arg2 are appended to arg1.. and returns the pointer of s1. If you dont want disturb str1,str2 then you have write your own function.

char * my_strcat(const char * str1, const char * str2)
{
   char * ret = malloc(strlen(str1)+strlen(str2));

   if(ret!=NULL)
   {
     sprintf(ret, "%s%s", str1, str2);
     return ret;
   }
   return NULL;    
}

Hope this solves your purpose

The only real use case for GROUP BY without aggregation is when you GROUP BY more columns than are selected, in which case the selected columns might be repeated. Otherwise you might as well use a DISTINCT.

It's worth noting that other RDBMS's do not require that all non-aggregated columns be included in the GROUP BY. For example in PostgreSQL if the primary key columns of a table are included in the GROUP BY then other columns of that table need not be as they are guaranteed to be distinct for every distinct primary key column. I've wished in the past that Oracle did the same as it would have made for more compact SQL in many cases.

Actually this is not a duplicate question. And this how i solve my problem after several times :

   int offset = DateTimeZone.forID("anytimezone").getOffset(new DateTime());

This is the way to get offset from desired timezone.

Let's return to our code, we were getting timestamp from a result set of query, and using it with timezone to create our datetime.

   DateTime dt = new DateTime(rs.getTimestamp("anytimestampcolumn"),
                         DateTimeZone.forID("anytimezone"));

Now we will add our offset to the datetime, and get the timestamp from it.

    dt = dt.plusMillis(offset);
    Timestamp ts = new Timestamp(dt.getMillis());

May be this is not the actual way to get it, but it solves my case. I hope it helps anyone who is stuck here.

Since API 17, the View class has a static method generateViewId() that will

generate a value suitable for use in setId(int)

use:

$('.modal.in').modal('hide')

Use Render Script as mentioned here http://blog.neteril.org/blog/2013/08/12/blurring-images-on-android/

Using MVVM Light Toolkit:

Assuming that there is an Exit command in view model:

ICommand _exitCommand;
public ICommand ExitCommand
{
    get
    {
        if (_exitCommand == null)
            _exitCommand = new RelayCommand<object>(call => OnExit());
        return _exitCommand;
    }
}

void OnExit()
{
     var msg = new NotificationMessageAction<object>(this, "ExitApplication", (o) =>{});
     Messenger.Default.Send(msg);
}

This is received in the view:

Messenger.Default.Register<NotificationMessageAction<object>>(this, (m) => if (m.Notification == "ExitApplication")
{
     Application.Current.Shutdown();
});

On the other hand, I handle Closing event in MainWindow, using the instance of ViewModel:

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{ 
    if (((ViewModel.MainViewModel)DataContext).CancelBeforeClose())
        e.Cancel = true;
}

CancelBeforeClose checks the current state of view model and returns true if closing should be stopped.

Hope it helps someone.

Should it be LIBRARY_PATH instead of LD_LIBRARY_PATH. gcc checks for LIBRARY_PATH which can be seen with -v option

As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:

<?php

    $world = _("World");

    $str = <<<EOF
    <p>Hello</p>
    <p>$world</p>
EOF;
    echo $str;
?>

a workaround idea that comes to mind is building a class with a magic getter method.

You would declare a class like this:

class Translator
{
 public function __get($name) {
  return _($name); // Does the gettext lookup
  }
 }

Initialize an object of the class at some point:

  $translate = new Translator();

You can then use the following syntax to do a gettext lookup inside a HEREDOC block:

    $str = <<<EOF
    <p>Hello</p>
    <p>{$translate->World}</p>
EOF;
    echo $str;
?>

$translate->World will automatically be translated to the gettext lookup thanks to the magic getter method.

To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!, you will have to use the following notation:

 $translate->{"Hello World!!!!!!"}

This is all untested but should work.

Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.

CSS only

    line-height: 1.5;
    white-space: normal;

There are several methods of showing a progress bar (circle) while loading an activity. In your case, one with a ListView in it.

IN ACTIONBAR

If you are using an ActionBar, you can call the ProgressBar like this (this could go in your onCreate()

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);  
setProgressBarIndeterminateVisibility(true);

And after you are done displaying the list, to hide it.

setProgressBarIndeterminateVisibility(false);

IN THE LAYOUT (The XML)

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/linlaHeaderProgress"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:orientation="vertical"
        android:visibility="gone" >

        <ProgressBar
            android:id="@+id/pbHeaderProgress"
            style="@style/Spinner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >
        </ProgressBar>
    </LinearLayout>

    <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:cacheColorHint="@android:color/transparent"
        android:divider="#00000000"
        android:dividerHeight="0dp"
        android:fadingEdge="none"
        android:persistentDrawingCache="scrolling"
        android:smoothScrollbar="false" >
    </ListView>
</LinearLayout>

And in your activity (Java) I use an AsyncTask to fetch data for my lists. SO, in the AsyncTask's onPreExecute() I use something like this:

// CAST THE LINEARLAYOUT HOLDING THE MAIN PROGRESS (SPINNER)
LinearLayout linlaHeaderProgress = (LinearLayout) findViewById(R.id.linlaHeaderProgress);

@Override
protected void onPreExecute() {    
    // SHOW THE SPINNER WHILE LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.VISIBLE);
}

and in the onPostExecute(), after setting the adapter to the ListView:

@Override
protected void onPostExecute(Void result) {     
    // SET THE ADAPTER TO THE LISTVIEW
    lv.setAdapter(adapter);

    // CHANGE THE LOADINGMORE STATUS TO PERMIT FETCHING MORE DATA
    loadingMore = false;

    // HIDE THE SPINNER AFTER LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.GONE);
}

EDIT: This is how it looks in my app while loading one of several ListViews

replace Range("A1") = "Asdf" with Range("A1").value = "Asdf"

Like you, I'm building a chat app and want the most recent message to scroll into view. This ultimately worked well for me:

//get the div that contains all the messages
let div = document.getElementById('message-container');

//make the last element (a message) to scroll into view, smoothly!
div.lastElementChild.scrollIntoView({ behavior: 'smooth' });

This seems like an old thread, but I'll add my experience here. I tried to install a cert as well and got that error. I then opened the cer file with a txt editor, and noticed that there is an extra space (character) at the end of each line. Removing those lines allowed me to import the cert.

Hope this is worth something to someone else.

Have you considered applying ON DELETE CASCADE where relevant?

For anyone on MacOS (I'm on Mojave 10.14), the following helped me out: https://github.com/reactioncommerce/reaction/issues/1938#issuecomment-284207213

You'd run these commands

echo kern.maxfiles=65536 | sudo tee -a /etc/sysctl.conf
echo kern.maxfilesperproc=65536 | sudo tee -a /etc/sysctl.conf
sudo sysctl -w kern.maxfiles=65536
sudo sysctl -w kern.maxfilesperproc=65536
ulimit -n 65536

Then try npm install once more.

I found a way to do it with plain old HTML and JavaScript/jQuery that degrades gracefully. Tested in IE7-10, Safari, Chrome, and FF:

HTML for download link:

<p>Thanks for downloading! If your download doesn't start shortly, 
<a id="downloadLink" href="...yourpdf.pdf" target="_blank" 
type="application/octet-stream" download="yourpdf.pdf">click here</a>.</p>

jQuery (pure JavaScript code would be more verbose) that simulates clicking on link after a small delay:

var delay = 3000;
window.setTimeout(function(){$('#downloadLink')[0].click();},delay);

To make this more robust you could add HTML5 feature detection and if it's not there then use window.open() to open a new window with the file.

printf already crops the trailing newline for you:

$ printf '%s' $(wc -l < log.txt)

Detail:

• printf will print your content in place of the %s string place holder.
• If you do not tell it to print a newline (%s\n), it won't.

If you don't know the name of params and want to work with them all, you can use request.GET.keys() or dict(request.GET) functions

Console.ReadLine();

or

Console.ReadKey();

ReadLine() waits for ?, ReadKey() waits for any key (except for modifier keys).

Edit: stole the key symbol from Darin.
