The tricky part here is to handle is the page event. We can follow angular material documentation up to defining page event function.

Visit https://material.angular.io/components/paginator/examples for the reference.

I will add my work with hours of hard work in this regard. in the relevant HTML file should look like as follows,

<pre>
<mat-paginator
    [pageSizeOptions]="pageSizeOptions"
    [pageSize]="Size"
    (page)="pageEvent = pageNavigations($event)"
    [length]="recordCount">
</mat-paginator>
</pre>

Then go to the relevant typescript file and following code,

declarations,

@Input('data') customers: Observable<Customer[]>;
pageEvent: PageEvent;
Page: number=0;
Size: number=2;
recordCount: number;
pageSizeOptions: number[] = [2,3,4,5];

The key part of page navigation as follows,

pageNavigations(event? : PageEvent){
    console.log(event);
    this.Page = event.pageIndex;
    this.Size = event.pageSize;
    this.reloadData();
  }

We require the following function to call data from the backend.

reloadData() {

    this.customers = this.customerService.setPageSize(this.Page ,this.Size);
    this.customerService.getSize().subscribe(res => {
      this.recordCount = Number(res);
     
      console.log(this.recordCount);
    });
  }

Before the aforementioned implementation, our services file should contain the following service call

setPageSize(page: number, size: number): Observable<any> {
    return this.http.get(`${this.baseUrl}?pageSize=${size}&pageNo=${page}`);
  }

Then all set to go and enable pagination in our app. Feel free to ask related questions thank you.

I have a good way to dynamically load scripts! Now I use ng6, echarts4 (>700Kb ) ,ngx-echarts3 in my project. when I use them by ngx-echarts's docs, I need import echarts in angular.json : "scripts":["./node_modules/echarts/dist/echarts.min.js"] thus in the login module, page while loading scripts.js, this is big file! I don't want it.

So, I think angular loads each module as a file, I can insert a router resolver to preload js, then begin the module loading!

// PreloadScriptResolver.service.js

/**????js??? */
@Injectable({
  providedIn: 'root'
})
export class PreloadScriptResolver implements Resolve<IPreloadScriptResult[]> {
  // Here import all dynamically js file
  private scripts: any = {
    echarts: { loaded: false, src: "assets/lib/echarts.min.js" }
  };
  constructor() { }
  load(...scripts: string[]) {
    const promises = scripts.map(script => this.loadScript(script));
    return Promise.all(promises);
  }
  loadScript(name: string): Promise<IPreloadScriptResult> {
    return new Promise((resolve, reject) => {
      if (this.scripts[name].loaded) {
        resolve({ script: name, loaded: true, status: 'Already Loaded' });
      } else {
        const script = document.createElement('script');
        script.type = 'text/javascript';
        script.src = this.scripts[name].src;
        script.onload = () => {
          this.scripts[name].loaded = true;
          resolve({ script: name, loaded: true, status: 'Loaded' });
        };
        script.onerror = (error: any) => reject({ script: name, loaded: false, status: 'Loaded Error:' + error.toString() });
        document.head.appendChild(script);
      }
    });
  }

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Promise<IPreloadScriptResult[]> {
   return this.load(...route.routeConfig.data.preloadScripts);
  }
}

Then in the submodule-routing.module.ts ,import this PreloadScriptResolver:

const routes: Routes = [
  {
    path: "",
    component: DashboardComponent,
    canActivate: [AuthGuardService],
    canActivateChild: [AuthGuardService],
    resolve: {
      preloadScripts: PreloadScriptResolver
    },
    data: {
      preloadScripts: ["echarts"]  // important!
    },
    children: [.....]
}

This code works well, and its promises that: After js file loaded, then module begin load! this Resolver can use in many routers

I just ran into this problem. When I ran npm start, I got a bunch of duplicate identifier errors.

SOLUTION:

From the project root folder run:

rm -r typings
typings install
npm start

and everything works fine.

Please note instead of

public TomcatEmbeddedServletContainerFactory tomcatFactory()

I had to use the following method signature

public EmbeddedServletContainerFactory embeddedServletContainerFactory() 

By using pandas we can read excel easily.

import pandas as pd 
from pandas import ExcelWriter
from pandas import ExcelFile 

DataF=pd.read_excel("Test.xlsx",sheet_name='Sheet1')

print("Column headings:")
print(DataF.columns)

Test at :https://repl.it Reference: https://pythonspot.com/read-excel-with-pandas/

You can also just redefine those non-enumerable properties to be enumerable.

Object.defineProperty(Error.prototype, 'message', {
    configurable: true,
    enumerable: true
});

and maybe stack property too.

In Spring Boot, The Regular expression solve the problem like

@GetMapping("/path/{param1:.+}")

I think that you can bind the load event of the iframe, the event fires when the iframe content is fully loaded.

At the same time you can start a setTimeout, if the iFrame is loaded clear the timeout alternatively let the timeout fire.

Code:

var iframeError;

function change() {
    var url = $("#addr").val();
    $("#browse").attr("src", url);
    iframeError = setTimeout(error, 5000);
}

function load(e) {
    alert(e);
}

function error() {
    alert('error');
}

$(document).ready(function () {
    $('#browse').on('load', (function () {
        load('ok');
        clearTimeout(iframeError);
    }));

});

Demo: http://jsfiddle.net/IrvinDominin/QXc6P/

Second problem

It is because you miss the parens in the inline function call; try change this:

<iframe id="browse" style="width:100%;height:100%" onload="load" onerror="error"></iframe>

into this:

<iframe id="browse" style="width:100%;height:100%" onload="load('Done func');" onerror="error('failed function');"></iframe>

RogerB over at CodeProject has one of the slickest solutions to this answer, and he did that back in '04, and it's still bangin'

Basically, you go here to his project and download the CS file. In case that link ever dies, I've got a backup gist here. Add the CS file to your project, or copy/paste the code somewhere if you'd rather do that.

Then, all you'd have to do is switch

DialogResult result = MessageBox.Show("Text","Title", MessageBoxButtons.CHOICE)

to

DialogResult result = MessageBoxEx.Show("Text","Title", MessageBoxButtons.CHOICE, timer_ms)

And you're good to go.

You can use any decompiler to first decompile the file.

I had once faced a simillar problem where I didn't have source code of the application and had to make a very small change in a file.

Below is what I did:

1. Extracted the class file from the jar

2. Opened it in a decompiler (I use JD GUI, you can get it easily from many resources on internet) You may download it from here

3. You can actually view all the files in a jar using JD GUI.

4. Made changes to the file I wanted to and copied all the code from that file
5. Created a new project in eclipse with only this class (with the same package structure as in the jar), provided the original jar as library and all other dependencies.
6. Compiled the class, injected the .class file back to the jar from bin folder of my workspace
7. Tested my change, celebrated it by sipping a cup of coffee :)

Tested in mysql 5.Dont know about other versions. If you want to keep the row with the lowest id value:

DELETE n1 FROM 'yourTableName' n1, 'yourTableName' n2 WHERE n1.id > n2.id AND n1.member_id = n2.member_id and n1.answer_num =n2.answer_num

If you want to keep the row with the highest id value:

DELETE n1 FROM 'yourTableName' n1, 'yourTableName' n2 WHERE n1.id < n2.id AND n1.member_id = n2.member_id and n1.answer_num =n2.answer_num

The example above can be simplify a bit. Additionally you can put date manually from keyboard instead of selecting it via datepicker only. When clearing the value you need to handle also 'on clearDate' action to remove startDate/endDate boundary:

JS file:

$(".from_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var startDate = new Date(selected.date.valueOf());
    $('.to_date').datepicker('setStartDate', startDate);
}).on('clearDate', function (selected) {
    $('.to_date').datepicker('setStartDate', null);
});

$(".to_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var endDate = new Date(selected.date.valueOf());
    $('.from_date').datepicker('setEndDate', endDate);
}).on('clearDate', function (selected) {
    $('.from_date').datepicker('setEndDate', null);
});

HTML:

<input class="from_date" placeholder="Select start date" type="text" name="from_date">
<input class="to_date" placeholder="Select end date" type="text" name="to_date">

I also faced this same issue while working in my development environment, the problem was that I left host: localhost commented out in the config/database.yml file.

So my application could not connect to the PostgreSQL database, simply uncommenting it solved the issue.

development:
  <<: *default
  database: database_name

  username: database_username 

  password: database_password

  host: localhost

That's all.

I hope this helps

Apache Commons has decorator for Map to expire entries: PassiveExpiringMap It's more simple than caches from Guava.

P.S. be careful, it's not synchronized.

Here's some background on the mechanism you should use, called Package Configurations: Understanding Integration Services Package Configurations. The article describes 5 types of configurations:

• XML configuration file
• Environment variable
• Registry entry
• Parent package variable
• SQL Server

Here's a walkthrough of setting up a configuration on a Connection Manager: SQL Server Integration Services SSIS Package Configuration - I do realize this is using an environment variable for the connection string (not a great idea), but the basics are identical to using an XML file. The only step(s) you have to change in that walkthrough are the configuration type, and then a path.

With Animation in Swift

scrollView.setContentOffset(CGPointMake(x, y), animated: true)

The phantom comments, adding // where you want new lines, are great!

1. The @formatter: off adds a reference from the code to the editor. The code should, in my opinion, never have such references.

2. The phantom comments (//) will work regardless of the formatting tool used. Regardless of Eclipse or InteliJ or whatever editor you use. This even works with the very nice Google Java Format

3. The phantom comments (//) will work all over your application. If you also have Javascript and perhaps use something like JSBeautifier. You can have similar code style also in the Javascript.

4. Actually, you probably DO want formatting right? You want to remove mixed tab/space and trailing spaces. You want to indent the lines according to the code standard. What you DONT want is a long line. That, and only that, is what the phantom comment gives you!

The default limit for the length of the request line is 8192 bytes = 8* 1024. It you want to change the limit, you have to add or update in your tomcat server.xml the attribut maxHttpHeaderSize.

as:

<Connector port="8080" maxHttpHeaderSize="65536" protocol="HTTP/1.1" ... />

In this example I set the limite to 65536 bytes= 64*1024.

Hope this will help.

Karl answered your search-path question, but as far as the "source of the files" goes, one thing to be aware of is that if you install the libfoo package and want to do some development with it (i.e., use its headers), you will also need to install libfoo-dev. The standard library header files are already in /usr/include, as you saw.

Note that some libraries with a lot of headers will install them to a subdirectory, e.g., /usr/include/openssl. To include one of those, just provide the path without the /usr/include part, for example:

#include <openssl/aes.h>

(Similar to Azder's answer, but a slightly different tact.)

I don't believe there is a predefined protocol handler for content from the classpath. (The so-called classpath: protocol).

However, Java does allow you to add your own protocols. This is done through providing concrete implementations java.net.URLStreamHandler and java.net.URLConnection.

This article describes how a custom stream handler can be implemented: http://java.sun.com/developer/onlineTraining/protocolhandlers/.

netcat (nc.exe) is the right tool. I have a feeling that any tool that does what you want it to do will have exactly the same problem with your antivirus software. Just flag this program as "OK" in your antivirus software (how you do this will depend on what type of antivirus software you use).

Of course you will also need to configure your sysadmin to accept that you're not trying to do anything illegal...

For Windows HTTP, you can't beat Fiddler. You can use it as a reverse proxy for port-forwarding on a web server. It doesn't necessarily need IE, either. It can use other clients.

For someone who is looking for a simplest script. No while (true), no if/else, no declaration.

Base on mwag's answer, but this one uses crypto.getRandomValues, a stronger random than Math.random.

Array(20)
  .fill('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz~!@-#$')
  .map(x => x[Math.floor(crypto.getRandomValues(new Uint32Array(1))[0] / (0xffffffff + 1) * x.length)])
  .join('');

See this for 0xffffffff.

Alternative 1

var generatePassword = (
  length = 20,
  wishlist = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz~!@-#$"
) => Array(length)
      .fill('')
      .map(() => wishlist[Math.floor(crypto.getRandomValues(new Uint32Array(1))[0] / (0xffffffff + 1) * wishlist.length)])
      .join('');

console.log(generatePassword());

Alternative 2

var generatePassword = (
  length = 20,
  wishlist = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz~!@-#$'
) =>
  Array.from(crypto.getRandomValues(new Uint32Array(length)))
    .map((x) => wishlist[x % wishlist.length])
    .join('')

console.log(generatePassword())

Node.js

const crypto = require('crypto')

const generatePassword = (
  length = 20,
  wishlist = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz~!@-#$'
) =>
  Array.from(crypto.randomFillSync(new Uint32Array(length)))
    .map((x) => wishlist[x % wishlist.length])
    .join('')

console.log(generatePassword())

You can scroll by jQuery and JavaScript Just need two element jQuery and this JavaScript code :

mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/… to get it rewritten to a corresponding /folder1/….

Try this:

RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1

This rule will rewrite every request that starts with the URI path /apple/… internally to /folder1/….

Edit    As you are actually looking for the other way round:

RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]

This rule is designed to work together with the other rule above. Requests of /folder1/… will be redirected externally to /apple/… and requests of /apple/… will then be rewritten internally back to /folder1/….

Debian appears to include the following:

• mpiCC.openmpi
• mpic++.openmpi
• mpicc.openmpi
• mpicxx.openmpi
• mpif77.openmpi
• mpif90.openmpi

I'll test symlinks of each for mpic, etc., and see if that helps the likes of HDF5-openmpi enabled find mpi.h.

Take that back Debian includes symlinks via their alternatives system and it still cannot find the proper paths between HDF5 openmpi packages and mpi.h referenced in the H5public.h header.

You won't need a plugin to see commit history with Visual Studio Code 1.42 or more.

Timeline view

In this milestone, we've made progress on the new Timeline view, and have an early preview to share.
This is a unified view for visualizing time-series events (e.g. commits, saves, test runs, etc.) for a resource (file, folder, etc.).

To enable the Timeline view, you must be using the Insiders Edition (VSCode 1.44 March 2020) and then add the following setting:

"timeline.showView": true

I'm working with Nob Hill's Marketing team, I wanted to tell you I'll be happy to hear your questions, suggestion or anything else, please feel free to contact me.

We originally decided to create our tool from scratch because while there are other such products on the market, none of them do the job right. It’s quite easy to show you the differences between databases. It’s quite another to actually make one database like the other. Smooth migration, both of schema and data, has always been a challenge. Well, we have achieved it here.
We are so confident that it could provide you a smooth migration, than if it doesn’t – if the migration scripts it generates are not readable enough or won’t work for you, and we can’t fix it in five business days – you will get your own free copy!

You want:

document.cookie = cookieName +"=" + cookieValue + ";domain=.example.com;path=/;expires=" + myDate;

As per the RFC 2109, to have a cookie available to all subdomains, you must put a . in front of your domain.

Setting the path=/ will have the cookie be available within the entire specified domain(aka .example.com).

If you care about reading that will always return the objects in the order they are inserted in a Dictionary, you may have a look at

OrderedDictionary - values can be accessed via an integer index (by order in which items were added) SortedDictionary - items are automatically sorted

I had same problem and solution was obj = ClassName.objects.filter()

You can also strip whitespace by passing in those variables with whitespace as parameters into a sub and then inside your sub simply set them again with the passed in parameters.

@echo off 
set "a=    apple      "
set "b=     banana    "
echo [%a%]
echo [%b%]
call :Strip %a% %b%
pause
goto :EOF

:Strip
set a=%1
set b=%2
echo [%a%]
echo [%b%]

----------------
Results....
[    apple      ]
[     banana    ]
[apple]
[banana]

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

A simple regex to match a numeric input and optional 2 digits decimal.

/^\d*(\.)?(\d{0,2})?$/

You can modify the {0,2} to match your decimal preference {min, max}

Snippet for validation:

const source = document.getElementById('source');
source.addEventListener('input', allowOnlyNumberAndDecimals);

function allowOnlyNumberAndDecimals(e) {
  let str = e.target.value
  const regExp = /^\d*(\.)?(\d{0,2})?$/

  status = regExp.test(str) ? 'valid' : 'invalid'

  console.log(status + ' : ' + source.value)
}

<input type="text" id="source" />

A really simple solution is just to edit the $state.current.name string and cut out everything including and after the last '.' - you get the name of the parent state. This doesn't work if you jump a lot between states because it just parses back the current path. But if your states correspond to where you actually are, then this works.

var previousState = $state.current.name.substring(0, $state.current.name.lastIndexOf('.'))
$state.go(previousState)

Just stick the img tag inside the h1 tag as part of the content.

cat < File > | awk '{if(NR > 6) print $0}'

You can consider using the C-Style while loop instead. This works just fine in Swift 3:

var i = 5 
while i > 0 { 
    print(i)
    i -= 1
}

If anyone is interested, here are some one-liners (and a note on loss of type information in CSV):

require 'csv'

rows = [[1,2,3],[4,5]]                    # [[1, 2, 3], [4, 5]]

# To CSV string
csv = rows.map(&:to_csv).join             # "1,2,3\n4,5\n"

# ... and back, as String[][]
rows2 = csv.split("\n").map(&:parse_csv)  # [["1", "2", "3"], ["4", "5"]]

# File I/O:
filename = '/tmp/vsc.csv'

# Save to file -- answer to your question
IO.write(filename, rows.map(&:to_csv).join)

# Read from file
# rows3 = IO.read(filename).split("\n").map(&:parse_csv)
rows3 = CSV.read(filename)

rows3 == rows2   # true

Note: CSV loses all type information, you can use JSON to preserve basic type information, or go to verbose (but more easily human-editable) YAML to preserve all type information -- for example, if you need date type, which would become strings in CSV & JSON.

For anyone who stumbles here with the issue I had (some but not all packages being restored on a build server), the final piece of the puzzle for me was adding a NuGet.config in the root of my solution, sibling to the .SLN file as David Ebbo explained here: http://blog.davidebbo.com/2014/01/the-right-way-to-restore-nuget-packages.html.

From Ebbo's blog post, the file contents for me are simply

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />
  </packageSources>
</configuration>

UPDATE:

The NuGet API URL has changed for v3 (current as of Sept 2016). From https://www.nuget.org/

<add key="nuget.org" value="https://api.nuget.org/v3/index.json" />

select convert(varchar(10), cast(fmdate as date), 101) from sery

Without cast I was not getting fmdate converted, so fmdate was a string.

I recommend looking at the dataset array.

The dataset array is a data type that ships with Statistics Toolbox. It is specifically designed to store hetrogeneous data in a single container.

The Statistics Toolbox demo page contains a couple vidoes that show some of the dataset array features. The first is titled "An Introduction to Dataset Arrays". The second is titled "An Introduction to Joins".

http://www.mathworks.com/products/statistics/demos.html

1. Highlight the column with the name
2. Data > Pivot Table and Pivot Chart
3. Next, Next layout
4. drag the column title to the row section
5. drag it again to the data section
6. Ok > Finish

This article on MSDN references a number of type aliases (available on Windows) that are a bit more explicit with respect to their width:

http://msdn.microsoft.com/en-us/library/aa505945.aspx

For instance, although you can use ULONGLONG to reference a 64-bit unsigned integral value, you can also use UINT64. (The same goes for ULONG and UINT32.) Perhaps these will be a bit clearer?

I also encounter the WindowLeaked problem when run monkey test.The logcat is below.

My Activity is AppCompatActivity.And I resovled it with the below code in the Activity.

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    // added by sunhang : intercept menu key to resove a WindowLeaked error in monkey-test.
    if (event.getKeyCode() == KeyEvent.KEYCODE_MENU) {
        return true;
    }
    return super.dispatchKeyEvent(event);
}

You can do it in 2 steeps:

1. Use the checkout for create the local branch:

git checkout -b yourBranchName

Work with your Branch as you want.

2. Use the push command to autocreate the branch and send the code to the remote repository:

git push -u origin yourBanchName

There are mutiple ways to do this but I think that this way is really simple.

PrjForm was set to ".Net Framework 4 Client Profile" I changed it to ".Net Framework 4", and now I have a successful build.

This worked for me too. Thanks a lot. I was trying an RDF example for dotNet where in I downloaded kit from dotnetrdf.

NET4 Client Profile: Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).

NET4 Full framework: Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes: If you are building Server apps, Such as:

• ASP.Net apps
• Server-side ASMX based web services

If you use legacy client scenarios, Such as: o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.

• Use legacy Windows Workflow Foundation 3.0 or 3.5 (WF3.0 , WF3.5)

If you targeting developer scenarios and need tool such as MSBuild or need access to design assemblies such as System.Design.dll

The function takes two arguments:

start - the start index;
length - the length of substring to capitalise

String.prototype.subUpper = function () {
    var result = this.toString();
    var start = 0;
    var length = 1;
    if (arguments.length > 0) {
        start = arguments[0];
        if (start < this.length) {
            if (arguments.length > 1) {
                length = arguments[1];
            }
            if (start + length > this.length) {
                length = this.length - start;
            }
            var startRest = start + length;
            var prefix = start > 0 ? this.substr(0, start) : String.empty;
            var sub = this.substr(start, length);
            var suffix = this.substr(startRest, this.length - startRest);
            result = prefix + sub.toUpperCase() + suffix;
        }
    }
    return result;
};

Referencing my comments on other answers. This is how I would work out the difference in days based on 24 hours and calender days. the days attribute works well for 24 hours and the function works best for calendar checks.

from datetime import timedelta, datetime

def cal_days_diff(a,b):

    A = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
    B = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
    return (A - B).days

if __name__ == '__main__':

    x = datetime(2013, 06, 18, 16, 00)
    y = datetime(2013, 06, 19, 2, 00)

    print (y - x).days          # 0
    print cal_days_diff(y, x)   # 1 

    z = datetime(2013, 06, 20, 2, 00)

    print (z - x).days          # 1
    print cal_days_diff(z, x)   # 2 

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

It seems compile issue. Run project as Maven test, then Run as JUnit Test.

The best practice is to reference the WSDL and use it like a web service reference. It's easier and works better, but if you don't have the WSDL, the XSD definitions are a good piece of code.

For Simple Direct Media Layer 2 (SDL2), after installing it on Ubuntu 16.04 via:

sudo apt-get install libsdl2-dev

I used the header:

#include <SDL2/SDL.h>  

and the compiler linker command:

-lSDL2main -lSDL2 

Additionally, you may also want to install:

apt-get install libsdl2-image-dev  
apt-get install libsdl2-mixer-dev  
apt-get install libsdl2-ttf-dev  

With these headers:

#include <SDL2/SDL_image.h>
#include <SDL2/SDL_ttf.h>
#include <SDL2/SDL_mixer.h>  

and the compiler linker commands:

-lSDL2_image 
-lSDL2_ttf 
-lSDL2_mixer

I'd like to propose

np.min(np.append(np.where(aa>5)[0],np.inf))

This will return the smallest index where the condition is met, while returning infinity if the condition is never met (and where returns an empty array).

I'd use absolute positioning:

#play_button {
    position:absolute;
transition: .5s ease;
    left: 202px;
    top: 198px;

}

It is kind of late, but I looked for e similar filter and ended using something like this:

<div ng-controller="TestCtrl">
 <div ng-repeat="(k,v) in items | filter:{secId: '!!'}">
   {{k}} {{v.pos}}
 </div>
</div>

PowerShell features a Restart-Service cmdlet, which either starts or restarts the service as appropriate.

The Restart-Service cmdlet sends a stop message and then a start message to the Windows Service Controller for a specified service. If a service was already stopped, it is started without notifying you of an error.

You can specify the services by their service names or display names, or you can use the InputObject parameter to pass an object that represents each service that you want to restart.

It is a little more foolproof than running two separate commands.

The easiest way to use it just pass either the service name or the display name directly:

Restart-Service 'Service Name'

It can be used directly from the standard cmd prompt with a command like:

powershell -command "Restart-Service 'Service Name'"

Just update your eclipse.ini file (you can find it in the root-directory of eclipse) by this:

-vm
path/javaw.exe

for example:

-vm 
C:/Program Files/Java/jdk1.7.0_09/jre/bin/javaw.exe

You can use this function in your application to add keys to indexed array.

public static function convertIndexedArrayToAssociative($indexedArr, $keys)
{
    $resArr = array();
    foreach ($indexedArr as $item)
    {
        $tmpArr = array();
        foreach ($item as $key=>$value)
        {
            $tmpArr[$keys[$key]] = $value;
        }
        $resArr[] = $tmpArr;
    }
    return $resArr;
}

This project https://github.com/FilipDeVos/sp_select has a stored procedure sp_select which allows for selecting from a temp table.

Usage:

exec sp_select 'tempDb..#myTempTable'

While debugging a stored procedure you can open a new tab and run this command to see the contents of the temp table.

As this question comes up again and again, here is one more answer. I hope to add something for beginners wondering about "best practice" here.

SELECT COUNT(*) FROM something counts records which is an easy task.

SELECT COUNT(1) FROM something retrieves a 1 per record and than counts the 1s that are not null, which is essentially counting records, only more complicated.

Having said this: Good dbms notice that the second statement will result in the same count as the first statement and re-interprete it accordingly, as not to do unnecessary work. So usually both statements will result in the same execution plan and take the same amount of time.

However from the point of readability you should use the first statement. You want to count records, so count records, not expressions. Use COUNT(expression) only when you want to count non-null occurences of something.

Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE - 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles.

It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar.

The first one is the JAR of the logmanager module generated during the package phase by jar:jar (because the module has a packaging of type jar). The second one is the assembly generated by assembly:assembly and should contain the classes from the current module and its dependencies (if you used the descriptor jar-with-dependencies).

I get an error when I double-click on the first jar:

Could not find the main class: com.gorkwobble.logmanager.LogManager. Program will exit.

If you applied the suggested configuration of the link posted as reference, you configured the jar plugin to produce an executable artifact, something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.gorkwobble.logmanager.LogManager</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>

So logmanager-0.1.0.jar is indeed executable but 1. this is not what you want (because it doesn't have all dependencies) and 2. it doesn't contain com.gorkwobble.logmanager.LogManager (this is what the error is saying, check the content of the jar).

A slightly different error when I double-click the jar-with-dependencies.jar:

Failed to load Main-Class manifest attribute from: C:\EclipseProjects\logmanager\target\logmanager-0.1.0-jar-with-dependencies.jar

Again, if you configured the assembly plugin as suggested, you have something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
  </plugin>

With this setup, logmanager-0.1.0-jar-with-dependencies.jar contains the classes from the current module and its dependencies but, according to the error, its META-INF/MANIFEST.MF doesn't contain a Main-Class entry (its likely not the same MANIFEST.MF as in logmanager-0.1.0.jar). The jar is actually not executable, which again is not what you want.

So, my suggestion would be to remove the configuration element from the maven-jar-plugin and to configure the maven-assembly-plugin like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <!-- nothing here -->
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-4</version>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>org.sample.App</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

Of course, replace org.sample.App with the class you want to have executed. Little bonus, I've bound assembly:single to the package phase so you don't have to run assembly:assembly anymore. Just run mvn install and the assembly will be produced during the standard build.

So, please update your pom.xml with the configuration given above and run mvn clean install. Then, cd into the target directory and try again:

java -jar logmanager-0.1.0-jar-with-dependencies.jar

If you get an error, please update your question with it and post the content of the META-INF/MANIFEST.MF file and the relevant part of your pom.xml (the plugins configuration parts). Also please post the result of:

java -cp logmanager-0.1.0-jar-with-dependencies.jar com.gorkwobble.logmanager.LogManager

to demonstrate it's working fine on the command line (regardless of what eclipse is saying).

EDIT: For Java 6, you need to configure the maven-compiler-plugin. Add this to your pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>

You can convert the java.util.Date object into a String object, which will format the date as yyyy-mm-dd.

LocalDate has a parse method that will convert it to a LocalDate object. The string must represent a valid date and is parsed using DateTimeFormatter.ISO_LOCAL_DATE.

Date to LocalDate

LocalDate.parse(Date.toString())

When encoding query values, either form, plus or percent-20, is valid; however, since the bandwidth of the internet isn't infinite, you should use plus, since it's two fewer bytes.

Looks like you want to use java.lang.Class.getResourceAsStream(String), see

How about this:

SELECT MONTH('March' + ' 1 2014') 

Would return 3.

How to use index in select statement?
this way:

   SELECT * FROM table1 USE INDEX (col1_index,col2_index)
    WHERE col1=1 AND col2=2 AND col3=3;

SELECT * FROM table1 IGNORE INDEX (col3_index)
WHERE col1=1 AND col2=2 AND col3=3;

SELECT * FROM t1 USE INDEX (i1) IGNORE INDEX (i2) USE INDEX (i2);

And many more ways check this

Do I need to explicitly specify?

• No, no Need to specify explicitly.
• DB engine should automatically select the index to use based on query execution plans it builds from @Tudor Constantin answer.
• The optimiser will judge if the use of your index will make your query run faster, and if it is, it will use the index. from @niktrl answer

goto,

Safari -> Preferences -> Advanced

then at the bottom tick Show Develop Menu in menu bar

then in the Develop Menu tick Disable Cross-Origin Restrictions

more efficient, due to less DOM lookups:

$('#multiselect1').multiselect({
    // ...
    onChange: function() {
        var selected = this.$select.val();
        // ...
    }
});

Yeah first method will work on any element called from elsewhere since it will always take the target element irrespective of id.

Are you sure you need a regex? It seems that you only need to know if a word is present in a string, so you can do:

>>> line = 'This,is,a,sample,string'
>>> "sample" in line
 True

git rebase -i HEAD~2

Here '2' is the number of commits you want to rebase.

'git rebase -i HEAD`

if you want to rebase all the commits.

Then you will be able to choose one of these options.

p, pick = use commit

r, reword = use commit, but edit the commit message

e, edit = use commit, but stop for amending

s, squash = use commit, but meld into previous commit

f, fixup = like "squash", but discard this commit's log message

x, exec = run command (the rest of the line) using shell

d, drop = remove commit

These lines can be re-ordered; they are executed from top to bottom. If you remove a line here THAT COMMIT WILL BE LOST. However, if you remove everything, the rebase will be aborted. Note that empty commits are commented out

You can simply remove that commit using option "d" or Removing a line that has your commit.

But boost::filesystem can do that: http://www.boost.org/doc/libs/1_37_0/libs/filesystem/example/simple_ls.cpp

Here is a dead simple solution that works on every browser and with cross domains:

First, this works on the concept that if the html page containing the iframe is set to a height of 100% and the iframe is styled using css to have a height of 100%, then css will automatically size everything to fit.

Here is the code:

<head>
<style type="text/css"> 
html {height:100%}
body {
margin:0;
height:100%;
overflow:hidden
}
</style>
</head>

<body>
<iframe allowtransparency=true frameborder=0 id=rf sandbox="allow-same-origin allow-forms allow-scripts" scrolling=auto src="http://www.externaldomain.com/" style="width:100%;height:100%"></iframe>
</body>

Well, I believe it's an "Old but Gold" question. The answer is: "It depends!". The performances are such a delicate subject that it would be too much silly to say: "Never use subqueries, always join". In the following links, you'll find some basic best practices that I have found to be very helpful:

• Optimizing Subqueries
• Optimizing Subqueries with Semijoin Transformations
• Rewriting Subqueries as Joins

I have a table with 50000 elements, the result i was looking for was 739 elements.

My query at first was this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND p.anno = (
    SELECT MAX(p2.anno) 
    FROM prodotto p2 
    WHERE p2.fixedId = p.fixedId 
)

and it took 7.9s to execute.

My query at last is this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND (p.fixedId, p.anno) IN
(
    SELECT p2.fixedId, MAX(p2.anno)
    FROM prodotto p2
    WHERE p.azienda_id = p2.azienda_id
    GROUP BY p2.fixedId
)

and it took 0.0256s

Good SQL, good.

EDIT: (As per the comments in question:)

I've been looking into this since then. I was lucky enough that I had repo laying around. Still it's not clear to me whether you need to enclose your commands between single quotes by force. I looked into the repo syntax and I don't think you need to. You could used double quotes around your command, and then use whatever single and double quotes you need inside provided you escape double ones.

I had the same issue, and had to satisfy all these requirements:

• Minified + Non minified version (as in the question)
• ES6
• Cross platform (Windows + Linux).

I finally solved it as follows:

webpack.config.js:

const path = require('path');
const MinifyPlugin = require("babel-minify-webpack-plugin");

module.exports = getConfiguration;

function getConfiguration(env) {
    var outFile;
    var plugins = [];
    if (env === 'prod') {
        outFile = 'mylib.dev';
        plugins.push(new MinifyPlugin());
    } else {
        if (env !== 'dev') {
            console.log('Unknown env ' + env + '. Defaults to dev');
        }
        outFile = 'mylib.dev.debug';
    }

    var entry = {};
    entry[outFile] = './src/mylib-entry.js';

    return {
        entry: entry,
        plugins: plugins,
        output: {
            filename: '[name].js',
            path: __dirname
        }
    };
}

package.json:

{
    "name": "mylib.js",
    ...
    "scripts": {
        "build": "npm-run-all webpack-prod webpack-dev",
        "webpack-prod": "npx webpack --env=prod",
        "webpack-dev": "npx webpack --env=dev"
    },
    "devDependencies": {
        ...
        "babel-minify-webpack-plugin": "^0.2.0",
        "npm-run-all": "^4.1.2",
        "webpack": "^3.10.0"
    }
}

Then I can build by (Don't forget to npm install before):

npm run-script build

Since I just lost two days of my life trying to solve for tryCatch for an irr function, I thought I should share my wisdom (and what is missing). FYI - irr is an actual function from FinCal in this case where got errors in a few cases on a large data set.

1. Set up tryCatch as part of a function. For example:

   irr2 <- function (x) {
     out <- tryCatch(irr(x), error = function(e) NULL)
     return(out)
   }
   

2. For the error (or warning) to work, you actually need to create a function. I originally for error part just wrote error = return(NULL) and ALL values came back null.

3. Remember to create a sub-output (like my "out") and to return(out).

Reduce() is..

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

It was ..

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

Change to

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

Also you can use in

1. find max

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

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

2. find an element that not repeated.

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

Use byte[] ptext = String.getBytes("UTF-8"); instead of getBytes(). getBytes() uses so-called "default encoding", which may not be UTF-8.

You can try the following

By.CssSelector("div.atag.btag")

Making column not null and adding default can also be done in the SSMS GUI.

1. As others have already stated, you can't set "not null" until all the existing data is "not null" like so:

UPDATE myTable SET myColumn = 0

2. Once that's done, with the table in design view (right click on table and click "design view"), you can just uncheck the Allow Nulls columns like so:

3. Still in design view with the column selected, you can see the Column Properties in the window below and set the default to 0 in there as well like so:

Continuing from the answers provided by Michael and testing, an important thing to keep in mind when translating the original Java code to C# is that Java and C# define their constants differently. C#, for instance, lacks Java's MIN_NORMAL, and the definitions for MinValue differ greatly.

Java defines MIN_VALUE to be the smallest possible positive value, while C# defines it as the smallest possible representable value overall. The equivalent value in C# is Epsilon.

The lack of MIN_NORMAL is problematic for direct translation of the original algorithm - without it, things start to break down for small values near zero. Java's MIN_NORMAL follows the IEEE specification of the smallest possible number without having the leading bit of the significand as zero, and with that in mind, we can define our own normals for both singles and doubles (which dbc mentioned in the comments to the original answer).

The following C# code for singles passes all of the tests given on The Floating Point Guide, and the double edition passes all of the tests with minor modifications in the test cases to account for the increased precision.

public static bool ApproximatelyEqualEpsilon(float a, float b, float epsilon)
{
    const float floatNormal = (1 << 23) * float.Epsilon;
    float absA = Math.Abs(a);
    float absB = Math.Abs(b);
    float diff = Math.Abs(a - b);

    if (a == b)
    {
        // Shortcut, handles infinities
        return true;
    }

    if (a == 0.0f || b == 0.0f || diff < floatNormal)
    {    
        // a or b is zero, or both are extremely close to it.
        // relative error is less meaningful here
        return diff < (epsilon * floatNormal);
    }

    // use relative error
    return diff / Math.Min((absA + absB), float.MaxValue) < epsilon;
}

The version for doubles is identical save for type changes and that the normal is defined like this instead.

const double doubleNormal = (1L << 52) * double.Epsilon;

You can use the following CTE as well. You can just modify it as you find fit. But this will add the same values into the student CTE.

This will add 1000 records but you can change it to 10000 or to a maximum of 32767

;WITH thetable(rowid,sname,semail,spassword) AS
(
    SELECT 1  , 'name' , 'email' , 'password'
    UNION ALL
    SELECT rowid+1 ,'name' , 'email' , 'password' 
    FROM thetable WHERE rowid < 1000
)

SELECT rowid,sname,semail,spassword 
FROM thetable ORDER BY rowid
OPTION (MAXRECURSION 1000);

In SQL, the order of the output is not defined unless you specify it in the ORDER BY clause.

Try this:

SELECT  *
FROM    one
JOIN    two
ON      one.one_name = two.one_name
ORDER BY
        one.id

In my case i change mysql_fetch_assoc to mysql_fetch_array and solve. It takes 3 days to solve :-( and the other versions of my proyect run with fetch assoc.

Give something like this a try:

$(document).ready(function(){
    $("#thisTable tr").click(function(){
        $(this).find("td").each(function(){
            alert($(this).html());
        });
    });
});?

Here is a fiddle of the code in action: http://jsfiddle.net/YhZsW/

This article may help you along the way: http://drewww.github.io/socket.io-benchmarking/

I wondered the same question, so I ended up writing a small test (using XHR-polling) to see when the connections started to fail (or fall behind). I found (in my case) that the sockets started acting up at around 1400-1800 concurrent connections.

This is a short gist I made, similar to the test I used: https://gist.github.com/jmyrland/5535279

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

If your query consists only of the $where operator, you can pass in just the JavaScript expression:

db.T.find("this.Grade1 > this.Grade2");

For greater performance, run an aggregate operation that has a $redact pipeline to filter the documents which satisfy the given condition.

The $redact pipeline incorporates the functionality of $project and $match to implement field level redaction where it will return all documents matching the condition using $$KEEP and removes from the pipeline results those that don't match using the $$PRUNE variable.

Running the following aggregate operation filter the documents more efficiently than using $where for large collections as this uses a single pipeline and native MongoDB operators, rather than JavaScript evaluations with $where, which can slow down the query:

db.T.aggregate([
    {
        "$redact": {
            "$cond": [
                { "$gt": [ "$Grade1", "$Grade2" ] },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

which is a more simplified version of incorporating the two pipelines $project and $match:

db.T.aggregate([
    {
        "$project": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] },
            "Grade1": 1,
            "Grade2": 1,
            "OtherFields": 1,
            ...
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

With MongoDB 3.4 and newer:

db.T.aggregate([
    {
        "$addFields": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] }
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

To write the JSON with indentation, "pretty print":

import json

outfile = open('data.json')
json.dump(data, outfile, indent=4)

Also, if you need to debug improperly formatted JSON, and want a helpful error message, use import simplejson library, instead of import json (functions should be the same)

To make the button is faded when disable, you can set alpha for it. There are two options for you:

First way: If you want to apply for all your buttons in your app, so you can write extension for UIButton like this:

extension UIButton {

    open override var isEnabled: Bool{
        didSet {
            alpha = isEnabled ? 1.0 : 0.5
        }
    }

}

Second way: If you just want to apply for some buttons in your app, so you can write a custom class from UIButton like below and use this class for which you want to apply:

class MyButton: UIButton {
    override var isEnabled: Bool {
        didSet {
            alpha = isEnabled ? 1.0 : 0.5
        }
    }
}

1. Somewhere, nearby the assembly you're going to run.
2. Use reflection to get path to your executing assembly, then do some magic to locate your HTML file.

Like this:

var myAssembly = System.Reflection.Assembly.GetEntryAssembly();
var myAssemblyLocation = System.IO.Path.GetDirectoryName(a.Location);
var myHtmlPath = Path.Combine(myAssemblyLocation, "my.html");

Try adding -Xmx for more memory ( java -Xmx1024M YourClass ), and don't forget to stop referencing variables you don't need any more (memory leaks).

Take a look at requirejs project.

JpaRepository extends PagingAndSortingRepository which in turn extends CrudRepository.

Their main functions are:

• CrudRepository mainly provides CRUD functions.
• PagingAndSortingRepository provides methods to do pagination and sorting records.
• JpaRepository provides some JPA-related methods such as flushing the persistence context and deleting records in a batch.

Because of the inheritance mentioned above, JpaRepository will have all the functions of CrudRepository and PagingAndSortingRepository. So if you don't need the repository to have the functions provided by JpaRepository and PagingAndSortingRepository , use CrudRepository.

You can make a shortcut somewhere and as the target use: python yourscript.py then under properties and advanced select run as administrator.

When the user executes the shortcut it will ask them to elevate the application.

<select id="cars">
<option value='volvo'>volvo</option>
<option value='bmw'>bmw</option>
<option value='fiat'>fiat</option>
</select>

var make = "fiat";

$("#cars option[value='" + make + "']").attr("selected","selected");

These all are ways:

String imageUri = "drawable://" + R.drawable.image;

Other ways I tested

Uri path = Uri.parse("android.resource://com.segf4ult.test/" + R.drawable.icon);
Uri otherPath = Uri.parse("android.resource://com.segf4ult.test/drawable/icon");

String path = path.toString();
String path = otherPath .toString();

This isn't a great answer, but if you know the target workstation has Powershell you can do something like this (assuming BAT / CMD script):

CALL:ECHORED "Print me in red!"

:ECHORED
%Windir%\System32\WindowsPowerShell\v1.0\Powershell.exe write-host -foregroundcolor Red %1
goto:eof

Edit: _{^{(now simpler!)}}

It's an old answer but I figured I'd clarify & simplify a bit

PowerShell is now included in all versions of Windows since 7. Therefore the syntax for this answer can be shortened to a simpler form:

• the path doesn't need to be specified since it should be in the environment variable already.
• unambiguous commands can be abbreviated. For example you can:
  • use -fore instead of -foregroundcolor
  • use -back instead of -backgroundcolor
• the command can also basically be used 'inline' in place of echo
  (rather than creating a separate batch file as above).

Example:

powershell write-host -fore Cyan This is Cyan text
powershell write-host -back Red This is Red background

More Information:

The complete list of colors and more information is available in the
- PowerShell Documentation for Write-Host

MSBuild is your friend.

msbuild "C:\path to solution\project.sln"

Use something like

ALTER TABLE T2
ADD CONSTRAINT fk_employee
FOREIGN KEY (employeeID)
REFERENCES T1 (employeeID)
ON DELETE CASCADE;

Fill in the correct column names and you should be set. As mark_s correctly stated, if you have already a foreign key constraint in place, you maybe need to delete the old one first and then create the new one.

All credits to @Martijn Pieters in the comments:

You can use the function last_insert_rowid():

The last_insert_rowid() function returns the ROWID of the last row insert from the database connection which invoked the function. The last_insert_rowid() SQL function is a wrapper around the sqlite3_last_insert_rowid() C/C++ interface function.

You can't do what I think you're asking to do.

The only privileges you can grant on procedures are EXECUTE and DEBUG.

If you want to allow user B to create a procedure in user A schema, then user B must have the CREATE ANY PROCEDURE privilege. ALTER ANY PROCEDURE and DROP ANY PROCEDURE are the other applicable privileges required to alter or drop user A procedures for user B. All are wide ranging privileges, as it doesn't restrict user B to any particular schema. User B should be highly trusted if granted these privileges.

EDIT:

As Justin mentioned, the way to give execution rights to A for a procedure owned by B:

GRANT EXECUTE ON b.procedure_name TO a;

Nice and concise way is to use Lombok annotations. It has @ToString annotation, which will generate an implementation of the toString() method. By default, it will print your class name, along with each field, in order, separated by commas. You can easily customize your output by passing parameters to annotation, e.g.:

@ToString(of = {"name", "lastName"})

Which is equivalent of pure Java:

public String toString() {
        return "Person(name=" + this.name + ", lastName=" + this.experienceInYears + ")";
    }

I'm guessing this will help.

When passed as functions arguments, arrays act the same way as pointers. So you don't need to reference them. Simply type: int x[] or int x[a] . Both ways will work. I guess its the same thing Konrad Rudolf was saying, figured as much.

What exactly IS unit testing? Is it built into code or run as separate programs? Or something else?

From MSDN: The primary goal of unit testing is to take the smallest piece of testable software in the application, isolate it from the remainder of the code, and determine whether it behaves exactly as you expect.

Essentially, you are writing small bits of code to test the individual bits of your code. In the .net world, you would run these small bits of code using something like NUnit or MBunit or even the built in testing tools in visual studio. In Java you might use JUnit. Essentially the test runners will build your project, load and execute the unit tests and then let you know if they pass or fail.

How do you do it?

Well it's easier said than done to unit test. It takes quite a bit of practice to get good at it. You need to structure your code in a way that makes it easy to unit test to make your tests effective.

When should it be done? Are there times or projects not to do it? Is everything unit-testable?

You should do it where it makes sense. Not everything is suited to unit testing. For example UI code is very hard to unit test and you often get little benefit from doing so. Business Layer code however is often very suitable for tests and that is where most unit testing is focused.

Unit testing is a massive topic and to fully get an understanding of how it can best benefit you I'd recommend getting hold of a book on unit testing such as "Test Driven Development by Example" which will give you a good grasp on the concepts and how you can apply them to your code.

Alter column data type with check type of column :

IF EXISTS(
       SELECT 1
       FROM   sys.columns
       WHERE  NAME = 'YourColumnName'
              AND [object_id] = OBJECT_ID('dbo.YourTable')
              AND TYPE_NAME(system_type_id) = 'int'
   )
    ALTER TABLE dbo.YourTable ALTER COLUMN YourColumnName BIT

If the below statment is present in your class then your log4j.properties should be in java source(src) folder , if it is jar executable it should be packed in jar not a seperate file.

static Logger log = Logger.getLogger(MyClass.class);

Thanks,

I think your ListBox already clear with ListBox2.Items.Clear(). The problem is that you also need to clear your dataset from previous results with ds6.Tables.Clear().

Add this in your code:

da6 = New SqlDataAdapter("select distinct(component_type) from component where   component_name='" & ListBox1.SelectedItem() & "'", con)
    ListBox1.Items.Clear()    ' clears ListBox1
    ListBox2.Items.Clear()    ' clears ListBox2
    ds6.Tables.Clear()        ' clears DataSet  <======= DON'T FORGET TO DO THIS
da6.Fill(ds6, "component")
For Each row As DataRow In ds6.Tables(0).Rows
    ListBox2.Items.Add(row.Field(Of String)("component_type"))
Next

It's one end of a communication channel, so often this would be represented as the URL of a server or service.

Snippet from http://msdn.microsoft.com/en-us/library/aa214566(office.11).aspx

you can't use aliases from select list inside the WHERE clause (because of the Order of Evaluation of a SELECT statement)

also you cannot use OVER clause inside WHERE clause - "You can specify analytic functions with this clause in the select list or ORDER BY clause." (citation from docs.oracle.com)

select *
from (select
  staff_id, site_id, pay_level, date, 
  max(date) over (partition by staff_id) max_date
  from owner.table
  where end_enrollment_date is null
)
where date = max_date

@Pete Becker's answer is fine but you can also do it without passing the class instance as an explicit parameter to function1 in C++ 11:

#include <functional>
using namespace std::placeholders;

void function1(std::function<void(int, int)> fun)
{
    fun(1, 1);
}

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

   aClass a;
   auto fp = std::bind(&aClass::test, a, _1, _2);
   function1(fp);

   return 0;
}

Look at the types of those properties:

In [1]: import datetime

In [2]: d = datetime.date.today()

In [3]: type(d.month)
Out[3]: <type 'int'>

In [4]: type(d.day)
Out[4]: <type 'int'>

Both are integers. So there is no automatic way to do what you want. So in the narrow sense, the answer to your question is no.

If you want leading zeroes, you'll have to format them one way or another. For that you have several options:

In [5]: '{:02d}'.format(d.month)
Out[5]: '03'

In [6]: '%02d' % d.month
Out[6]: '03'

In [7]: d.strftime('%m')
Out[7]: '03'

In [8]: f'{d.month:02d}'
Out[8]: '03'

for resizing my table I went with this solution in my tableview controller witch is perfectly fine:

The resizing part is in a method but here is just so you can see it. Now the only problem I haveis resizing the scroll view in the other view controller as I have no idea when the tableview has finished resizing. At the moment I'm doing it with performSelector: afterDelay: but this is really not a good way to do it. Any ideas?

Combining @Joachim's with the above, you could use

next(iter(my_list[index:index+1]), default)

Examples:

next(iter(range(10)[8:9]), 11)
8
>>> next(iter(range(10)[12:13]), 11)
11

Or, maybe more clear, but without the len

my_list[index] if my_list[index:index + 1] else default

To answer the second part of your question - there are no pointers in PHP.

When working with objects, you generally pass by reference rather than by value - so in some ways this operates like a pointer, but is generally completely transparent.

This does depend on the version of PHP you are using.

Easiest way is to ignore the csv module and format it yourself.

with open('my_file.csv', 'w') as f:
    [f.write('{0},{1}\n'.format(key, value)) for key, value in my_dict.items()]

Public - means that the class (program) is available for use by any other class.

Static - creates a class. Can also be applied to variables and methods,making them class methods/variables instead of just local to a particular instance of the class.

Void - this means that no product is returned when the class completes processing. Compare this with helper classes that provide a return value to the main class,these operate like functions; these do not have void in the declaration.

13 September 2018 It worked for me when add more types and set universalApk with false to reduce apk size

splits {
    abi {
        enable true
        reset()
        include 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a'
        universalApk false
    }
}

We can use elasticdump or multielasticdump to take the backup and restore it, We can move data from one server/cluster to another server/cluster.

Please find a detailed answer which I have provided here.

Create an IBOutlet of NSLayoutConstraint of yourView and update the constant value accordingly the condition specifies.

//Connect them from Interface 
@IBOutlet viewHeight: NSLayoutConstraint! 
@IBOutlet view: UIView!

private func updateViewHeight(height:Int){
   guard let aView = view, aViewHeight = viewHeight else{
      return
   }
   aViewHeight.constant = height
   aView.layoutIfNeeded()
}

Do you mean that the formatter does not break long lines? Check Settings / Project Settings / Code Style / Wrapping.

Update: in later versions of IntelliJ, the option is under Settings / Editor / Code Style. And select Wrap when typing reaches right margin.

You can try downloading the Windows binaries for pip from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pip.

Your code is passing a function as an argument to find. That function takes an element argument (of type Conversation) and returns void (meaning there is no return value). TypeScript describes this as (element: Conversation) => void'

What TypeScript is saying is that the find function doesn't expect to receive a function that takes a Conversation and returns void. It expects a function that takes a Conversations, a number and a Conversation array, and that this function should return a boolean.

So bottom line is that you either need to change your code to pass in the values to find correctly, or else you need to provide an overload to the definition of find in your definition file that accepts a Conversation and returns void.

I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.

The given code given will work absolutely fine if we run from console. and there is no package name in the class

You have to make sure where you have your ".class" file. because, if package name is given for the class, you have to make sure to keep the ".class" file inside the specified folder. For example, my package name is "src.main.code" , I have to create a code folder,inside main folder, inside src folder and put Test.class in code folder. then it will work perfectly.

as compared from the answer gven by mic... it doesnt validate anything in some of the platforms which i work upon... to be precise it doesnt actually work out in Dream Viewer..

hereby.. i re-write it again..which will work on any platform.. "^[0-9]+(.[0-9]{1,2})?$".. thnkss..

1. Add an exit handler that closes all the bars.
2. __del__() gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.
3. If __init__() raises an exception then the object is assumed to be incomplete and __del__() won't be invoked.

this is one of the ways you can use this function, it is when you want access a variable of another class and change the output based on that variable.

   override func prepare(for segue: UIStoryboardSegue, sender: Any?)  {
        let something = segue.destination as! someViewController
       something.aVariable = anotherVariable
   }

Function overloading - functions with same name, but different number of arguments

Function overriding - concept of inheritance. Functions with same name and same number of arguments. Here the second function is said to have overridden the first

Actually link to .well-know is on the first tab of your realm settings - but link doesn't look like link, but as value of text box... bad ui design. Screenshot of Realm's General Tab

If running on windows vista or later,
remember to run eclipse under a user with proper file permissions.
try to use the 'Run as Administrator' option.

yum list installed | grep mysql

Then if it's not installed you can do (as root)

yum install mysql -y

in redhat base OS (tested in centos 7)

yum install nodejs npm -y

in debian base OS

apt-get install -y npm    

Worked for me perfectly as this:

Trims all selected cells. Beware of selecting full columns/rows :P.

Sub TrimSelected()    
Dim rng As Range, cell As Range    
Set rng = Selection   

For Each cell In rng    
cell = Trim(cell)   

Next cell    

End Sub

function truncate ($str, $length) {
    if (strlen($str) > $length) {
        $str = substr($str, 0, $length+1);
        $pos = strrpos($str, ' ');
        $str = substr($str, 0, ($pos > 0)? $pos : $length);
    }
    return $str;
}

Example:

print truncate('The first step to eternal life is you have to die.', 25);

string(25) "The first step to eternal"

print truncate('The first step to eternal life is you have to die.', 12);

string(9) "The first"

print truncate('FirstStepToEternalLife', 5);

string(5) "First"

Just use the statement:

break;

You're setting the Content-Type to be multipart/form-data, but then using JSON.stringify on the body data, which returns application/json. You have a content type mismatch.

You will need to encode your data as multipart/form-data instead of json. Usually multipart/form-data is used when uploading files, and is a bit more complicated than application/x-www-form-urlencoded (which is the default for HTML forms).

The specification for multipart/form-data can be found in RFC 1867.

For a guide on how to submit that kind of data via javascript, see here.

The basic idea is to use the FormData object (not supported in IE < 10):

async function sendData(url, data) {
  const formData  = new FormData();

  for(const name in data) {
    formData.append(name, data[name]);
  }

  const response = await fetch(url, {
    method: 'POST',
    body: formData
  });

  // ...
}

Per this article make sure not to set the Content-Type header. The browser will set it for you, including the boundary parameter.

SIMPLE ANSWER:

   onclick="functionName(ID.value);

Where ID is the ID of the input field.

jQuery.fn.swap = function(b){ 
    b = jQuery(b)[0]; 
    var a = this[0]; 
    var t = a.parentNode.insertBefore(document.createTextNode(''), a); 
    b.parentNode.insertBefore(a, b); 
    t.parentNode.insertBefore(b, t); 
    t.parentNode.removeChild(t); 
    return this; 
};

and use it like this:

$('#div1').swap('#div2');

if you don't want to use jQuery you could easily adapt the function.

Not for entire application or particular class.

CurrentUICulture and CurrentCulture are settable per thread as discussed here Is there a way of setting culture for a whole application? All current threads and new threads?. You can't change InvariantCulture at all.

Sample code to change cultures for current thread:

CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;

For class you can set/restore culture inside critical methods, but it would be significantly safe to use appropriate overrides for most formatting related methods that take culture as one of arguments:

(3.3).ToString(new CultureInfo("fr-FR"))

You might look at how pygame handles this to steal some ideas.

if you wish to using dplyr, for to remove row "Foo":

df %>%
 filter(!C=="Foo")

For me it was the "Start In" - I copied the values from an older server, and updated the path to the new .exe location, but I forgot to update the "start in" location - if it doesn't exist, you get this error too

Quoting @hans-passant 's comment from above, because it is valuable to debugging this issue:

Convert the error code to hex to get 0x8007010B. The 7 makes it a Windows error. Which makes 010B error code 267. "The directory name is invalid". Sure, that happens.

We can do it nicely using Interceptors. You dont have to set options in all your services neither manage all your error responses, just define 2 interceptors (one to do something before sending the request to server and one to do something before sending the server's response to your service)

1. Define an AuthInterceptor class to do something before sending the request to the server. You can set the api token (retrieve it from localStorage, see step 4) and other options in this class.
2. Define an responseInterceptor class to do something before sending the server response to your service (httpClient). You can manage your server response, the most comon use is to check if the user's token is valid (if not clear token from localStorage and redirect to login).

3. In your app.module import HTTP_INTERCEPTORS from '@angular/common/http'. Then add to your providers the interceptors (AuthInterceptor and responseInterceptor). Doing this your app will consider the interceptors in all our httpClient calls.

4. At login http response (use http service), save the token at localStorage.

5. Then use httpClient for all your apirest services.

One quick way to do this is to create a column with a formula that evaluates to true for the rows you care about and then filter for the value TRUE in that column.

EDIT Summary and reccomendations

Using a for each cell in range construct is not in itself slow. What is slow is repeated access to Excel in the loop (be it reading or writing cell values, format etc, inserting/deleting rows etc).

What is too slow depends entierly on your needs. A Sub that takes minutes to run might be OK if only used rarely, but another that takes 10s might be too slow if run frequently.

So, some general advice:

1. keep it simple at first. If the result is too slow for your needs, then optimise
2. focus on optimisation of the content of the loop
3. don't just assume a loop is needed. There are sometime alternatives
4. if you need to use cell values (a lot) inside the loop, load them into a variant array outside the loop.
5. a good way to avoid complexity with inserts is to loop the range from the bottom up
   (for index = max to min step -1)
6. if you can't do that and your 'insert a row here and there' is not too many, consider reloading the array after each insert
7. If you need to access cell properties other than value, you are stuck with cell references
8. To delete a number of rows consider building a range reference to a multi area range in the loop, then delete that range in one go after the loop

eg (not tested!)

Dim rngToDelete as range
for each rw in rng.rows
    if need to delete rw then

        if rngToDelete is nothing then
            set rngToDelete = rw
        else
            set rngToDelete = Union(rngToDelete, rw)
        end if

    endif
next
rngToDelete.EntireRow.Delete

Original post

Conventional wisdom says that looping through cells is bad and looping through a variant array is good. I too have been an advocate of this for some time. Your question got me thinking, so I did some short tests with suprising (to me anyway) results:

test data set: a simple list in cells A1 .. A1000000 (thats 1,000,000 rows)

Test case 1: loop an array

Dim v As Variant
Dim n As Long

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    'i = i + 1
    'i = r.Cells(n, 1).Value 'i + 1
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Array Count = " & Format(n, "#,###")

Result:

Array Time = 0.249 sec
Array Count = 1,000,001

Test Case 2: loop the range

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 0.296 sec
Range Count = 1,000,000

So,looping an array is faster but only by 19% - much less than I expected.

Test 3: loop an array with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    i = r.Cells(n, 1).Value
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Array Count = " & Format(i, "#,###")

Result:

Array Time = 5.897 sec
Array Count = 1,000,000

Test case 4: loop range with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
    i = c.Value
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 2.356 sec
Range Count = 1,000,000

So event with a single simple cell reference, the loop is an order of magnitude slower, and whats more, the range loop is twice as fast!

So, conclusion is what matters most is what you do inside the loop, and if speed really matters, test all the options

FWIW, tested on Excel 2010 32 bit, Win7 64 bit All tests with

• ScreenUpdating off,
• Calulation manual,
• Events disabled.

I'm using Eclipse and I copied your code and got the same error. I then opened up the project properties->Java Build Path -> Libraries->Add External JARs... c:\jrun4\lib\sqlitejdbc-v056.jar Worked like a charm. You may need to restart your web server if you've just copied the .jar file.

Your SELECT statement isn't finding the data you're looking for. That is, there is no record in the ENROLLMENT table with the given STUDENT_ID and SECTION_ID. You may want to try putting some DBMS_OUTPUT.PUT_LINE statements before you run the query, printing the values of v_student_id and v_section_id. They may not be containing what you expect them to contain.

After searching for a while I have found a solution to comment on an AZERTY mac. The shortcut is Ctrl +/= key

Try this :

import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;


public class Test {

    public static void main(String[] args) {
        JFrame f = new JFrame();
        try {
            f.setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("test.jpg")))));
        } catch (IOException e) {
            e.printStackTrace();
        }
        f.pack();
        f.setVisible(true);
    }

}

By the way, this will result in the content pane not being a container. If you want to add things to it you have to subclass a JPanel and override the paintComponent method.

bool isMultiple = a % b == 0;

This will be true if a is a multiple of b

YapDi is a relatively new python module that popped up in Hacker News. Looks pretty useful, can be used to convert a python script into daemon mode from inside the script.

This works fine

public class DateDemo {
    public static void main(String[] args) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy hh:mm");
        String date = "16-08-2018 12:10";
        LocalDate localDate = LocalDate.parse(date, formatter);
        System.out.println("VALUE="+localDate);

        DateTimeFormatter formatter1 = DateTimeFormatter.ofPattern("dd-MM-yyyy HH:mm");
        LocalDateTime parse = LocalDateTime.parse(date, formatter1);
        System.out.println("VALUE1="+parse);
    }
}

output:

VALUE=2018-08-16
VALUE1=2018-08-16T12:10

I know its late but i recently ran into this situation. After wasting entire day I finally found the solution. I am suprised that I got this info on oracle's website whereas this seems nowhere to be found on IBM's website.

If you want to use JDBC drivers for DB2 that are compatible with JDK 1.5 or 1.4 , you need to use the jar db2jcc.jar, which is available in SQLLIB/java/ folder of your db2 installation.

You get that error because you don't have the public key of the person who signed the message.

gpg should have given you a message containing the ID of the key that was used to sign it. Obtain the public key from the person who encrypted the file and import it into your keyring (gpg2 --import key.asc); you should be able to verify the signature after that.

If the sender submitted its public key to a keyserver (for instance, https://pgp.mit.edu/), then you may be able to import the key directly from the keyserver:

gpg2 --keyserver https://pgp.mit.edu/ --search-keys <sender_name_or_address>

The variable mean_data is a nested list, in Python accessing a nested list cannot be done by multi-dimensional slicing, i.e.: mean_data[1,2], instead one would write mean_data[1][2].

This is becausemean_data[2] is a list. Further indexing is done recursively - since mean_data[2] is a list, mean_data[2][0] is the first index of that list.

Additionally, mean_data[:][0] does not work because mean_data[:] returns mean_data.

The solution is to replace the array ,or import the original data, as follows:

mean_data = np.array(mean_data)

numpy arrays (like MATLAB arrays and unlike nested lists) support multi-dimensional slicing with tuples.

As you might already know, you can customize your indention settings in Preferences.sublime-settings, for example:

"detect_indentation": true,
"tab_size": 4,
"translate_tabs_to_spaces": false

This will set your editor to use tabs that are 4 spaces wide and will override the default behavior that causes Sublime to match the indention of whatever file you're editing. With these settings, re-indenting the file will cause any spaces to be replaced with tabs.

As far as automatically re-indenting when opening a file, that's not quite as easy (but probably isn't a great idea since whitespace changes wreak havoc on file diffs). What might be a better course of action: you can map a shortcut for re-indention and just trigger that when you open a new file that needs fixing.

While the above answers work but in case you have multiple devices connected to your computer then the following command can be used to remove the app from one of them:

adb -s <device-serial> shell pm uninstall <app-package-name>

If you want to find out the device serial then use the following command:

adb devices -l

This will give you a list of devices attached. The left column shows the device serials.

You need to enable the option

Project Properties -> Build -> Packaging -> Build JAR after compiling

(but this is enabled by default)

Visual Studio : Right Bottom : Look for OVR label. Double Click on it.

Bingo...

The -R, --relative option will do this.

For example: if you want to backup /var/named/chroot and create the same directory structure on the remote server then -R will do just that.

Notice that in most suggestions the initial random value that you have got from rand() function, which is typically from 0 to RAND_MAX, is simply wasted. You are creating only one random number out of it, while there is a sound procedure that can give you more.

Assume that you want [min,max] region of integer random numbers. We start from [0, max-min]

Take base b=max-min+1

Start from representing a number you got from rand() in base b.

That way you have got floor(log(b,RAND_MAX)) because each digit in base b, except possibly the last one, represents a random number in the range [0, max-min].

Of course the final shift to [min,max] is simple for each random number r+min.

int n = NUM_DIGIT-1;
while(n >= 0)
{
    r[n] = res % b;
    res -= r[n];
    res /= b;
    n--;
}

If NUM_DIGIT is the number of digit in base b that you can extract and that is

NUM_DIGIT = floor(log(b,RAND_MAX))

then the above is as a simple implementation of extracting NUM_DIGIT random numbers from 0 to b-1 out of one RAND_MAX random number providing b < RAND_MAX.

Identity = Name with Location

Every URL(Uniform Resource Locator) is a URI(Uniform Resource Identifier), abstractly speaking, but every URI is not a URL. There is another subcategory of URI is URN (Uniform Resource Name), which is a named resource but do not specify how to locate them, like mailto, news, ISBN is URIs. Source

URN:

• URN Format : urn:[namespace identifier]:[namespace specific string]
• urn: and : stand for themselves.
• Examples:
  • urn:uuid:6e8bc430-9c3a-11d9-9669-0800200c9a66
  • urn:ISSN:0167-6423
  • urn:isbn:096139210x
  • Amazon Resource Names (ARNs) is a uniquely identify AWS resources.
    • ARN Format : arn:partition:service:region:account-id:resource

URL:

• URL Format : [scheme]://[Domain][Port]/[path]?[queryString]#[fragmentId]
• :,//,? and # stand for themselves.
• schemes are https,ftp,gopher,mailto,news,telnet,file,man,info,whatis,ldap...
• Examples:
  • http://ip_server/path?query
  • ftp://ip_server/path
  • mailto:email-address
  • news:newsgroup-name
  • telnet://ip_server/

I think much has already been said, about RSS vs VSZ. From an administrator/programmer/user perspective, when I design/code applications I am more concerned about the RSZ, (Resident memory), as and when you keep pulling more and more variables (heaped) you will see this value shooting up. Try a simple program to build malloc based space allocation in loop, and make sure you fill data in that malloc'd space. RSS keeps moving up. As far as VSZ is concerned, it's more of virtual memory mapping that linux does, and one of its core features derived out of conventional operating system concepts. The VSZ management is done by Virtual memory management of the kernel, for more info on VSZ, see Robert Love's description on mm_struct and vm_struct, which are part of basic task_struct data structure in kernel.

You do it by stacking case labels:

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7: 
    case 12:
    ...
    break;
    ...
}

I think you really need pandoc, which great software was designed and built just for this task :) Besides pdf, you could convert your md file to e.g. docx or odt among others.

Well, installing an up-to-date version of Pandoc might be challanging on Linux (as you would need the entire haskell-platform?to build from the sources), but really easy on Windows/Mac with only a few megabytes of download.

If you have the brewed/knitted markdown file you can just call pandoc in e.g bash or with the system function within R. A POC demo of that latter is implemented in the ?andoc.convert function of my little package (which you must be terribly bored of as I try to point your attention there at every opportunity).

I think toEqual is checking deep equal, toBe is the same reference of 2 variable

  it('test me', () => {
    expect([] === []).toEqual(false) // true
    expect([] == []).toEqual(false) // true

    expect([]).toEqual([]); // true // deep check
    expect([]).toBe([]); // false
  })

Example from current code I'm working with:

int index=-1;
for (Policy rule : rules)
{   
     index++;
     // do stuff here
}

Lets you cleanly start with an index of zero, and increment as you process.

If the other solutions don't work for you, try this:

Step 1: (if your installation is in webroot)

Replace

    #RewriteBase /magento/

with

    RewriteBase /

Step 2:

Add following lines (inclusive exclude admin because backend needs index.php internally)

RewriteCond %{THE_REQUEST} ^.*/index.php
RewriteRule ^(.*)index.php$ http://www.yourdomain.com/$1 [R=301,L]
RewriteRule ^index.php/(admin|user)($|/) - [L]
RewriteRule ^index.php/(.*) $1 [R=301,QSA,L]

right after

RewriteRule .* index.php [L] 

This works for me

In case it is still not working, double check Magento configuration: System->Configuration->Web->Search Engine Optimization. Rewrites must be enabled.

I showed my hide directories in windows 7 and find git.exe in C:\Users\(UserName)\AppData\Local\GitHub\PortableGit_c2ba306e536fdf878271f7fe636a147ff37326ad\bin\ and it works but I don't know why git.exe is there. I installed git version 1.9.5

If you include ALL references to the spreadsheet data in the UDF parameter list, Excel will recalculate your function whenever the referenced data changes:

Public Function doubleMe(d As Variant)
    doubleMe = d * 2
End Function

You can also use Application.Volatile, but this has the disadvantage of making your UDF always recalculate - even when it does not need to because the referenced data has not changed.

Public Function doubleMe()
    Application.Volatile
    doubleMe = Worksheets("Fred").Range("A1") * 2
End Function

also check the PGHOST variable:

ECHO $PGHOST

to see if it matches the local machine name

Boxing isn't really something that you use - it is something the runtime uses so that you can handle reference and value types in the same way when necessary. For example, if you used an ArrayList to hold a list of integers, the integers got boxed to fit in the object-type slots in the ArrayList.

Using generic collections now, this pretty much goes away. If you create a List<int>, there is no boxing done - the List<int> can hold the integers directly.

Took DonkeyKong's example.

The issue is I needed to use a declared variable. This allows for stating your left and right-hand side of what you need to compare. This is for supporting an SSRS report where different fields must be linked based on the selection by the user.

The initial case sets the field choice based on the selection and then I can set the field I need to match on for the join.

A second case statement could be added for the right-hand side if the variable is needed to choose from different fields

LEFT OUTER JOIN Dashboard_Group_Level_Matching ON
       case
         when @Level  = 'lvl1' then  cw.Lvl1
         when @Level  = 'lvl2' then  cw.Lvl2
         when @Level  = 'lvl3' then  cw.Lvl3
       end
    = Dashboard_Group_Level_Matching.Dashboard_Level_Name

Use:

subA.tick_params(labelsize=6)

For strings, you can use string.c_str() which will return you a const char*, which can be treated as an array, example:

const char* strdata = str.c_str();

for (int i = 0; i < str.length(); ++i)
    cout << i << strdata[i];

The documentation could help you : http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html

The method DocumentBuilder.parse(String) takes a URI and tries to open it. If you want to directly give the content, you have to give it an InputStream or Reader, for example a StringReader. ... Welcome to the Java standard levels of indirections !

Basically :

DocumentBuilder db = ...;
String xml = ...;
db.parse(new InputSource(new StringReader(xml)));

Note that if you read your XML from a file, you can directly give the File object to DocumentBuilder.parse() .

As a side note, this is a pattern you will encounter a lot in Java. Usually, most API work with Streams more than with Strings. Using Streams means that potentially not all the content has to be loaded in memory at the same time, which can be a great idea !

I know this post is very old, For those who don't want to use android:fillViewport="true" because it sometimes doesn't bring up the edittext above keyboard. Use Relative layout instead of LinearLayout it solves the purpose.

Since the originating port 4200 is different than 8080,So before angular sends a create (PUT) request,it will send an OPTIONS request to the server to check what all methods and what all access-controls are in place. Server has to respond to that OPTIONS request with list of allowed methods and allowed origins.

Since you are using spring boot, the simple solution is to add ".allowedOrigins("http://localhost:4200");"

In your spring config,class

@Configuration
@EnableWebMvc
public class SpringConfig implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedOrigins("http://localhost:4200");
    }
}

However a better approach will be to write a Filter(interceptor) which adds the necessary headers to each response.

I believe I ran exactly into the same issue. After countless hours of fighting with the JSON, the JavaScript and the Server, I found the culprit: In my case I had a Date object in the DTO, this Date object was converted to a String so we could show it in the view with the format: HH:mm.

When JSON information was being sent back, this Date String object had to be converted back into a full Date Object, therefore we also need a method to set it in the DTO. The big BUT is you cannot have 2 methods with the same name (Overload) in the DTO even if they have different type of parameter (String vs Date) because this will give you also the 415 Unsupported Media type error.

This was my controller method

  @RequestMapping(value = "/alarmdownload/update", produces = "application/json", method = RequestMethod.POST)
  public @ResponseBody
  StatusResponse update(@RequestBody AlarmDownloadDTO[] rowList) {
    System.out.println("hola");
    return new StatusResponse();
  }

This was my DTO example (id get/set and preAlarm get Methods are not included for code shortness):

@JsonIgnoreProperties(ignoreUnknown = true)
public class AlarmDownloadDTO implements Serializable {

  private static final SimpleDateFormat formatHHmm = new SimpleDateFormat("HH:mm");

  private String id;
  private Date preAlarm;

  public void setPreAlarm(Date date) { 
    this.preAlarm == date;
  }
  public void setPreAlarm(String date) {    
    try {
      this.preAlarm = formatHHmm.parse(date);
    } catch (ParseException e) {
      this.preAlarm = null;
    } catch (NullPointerException e){
      this.preAlarm = null;
    }
  }
}

To make everything work you need to remove the method with Date type parameter. This error is very frustrating. Hope this can save someone hours of debugging.

Calling addView is the correct answer, but you need to do a little more than that to get it to work.

If you create a View via a constructor (e.g., Button myButton = new Button();), you'll need to call setLayoutParams on the newly constructed view, passing in an instance of the parent view's LayoutParams inner class, before you add your newly constructed child to the parent view.

For example, you might have the following code in your onCreate() function assuming your LinearLayout has id R.id.main:

LinearLayout myLayout = findViewById(R.id.main);

Button myButton = new Button(this);
myButton.setLayoutParams(new LinearLayout.LayoutParams(
                                     LinearLayout.LayoutParams.MATCH_PARENT,
                                     LinearLayout.LayoutParams.MATCH_PARENT));

myLayout.addView(myButton);

Making sure to set the LayoutParams is important. Every view needs at least a layout_width and a layout_height parameter. Also getting the right inner class is important. I struggled with getting Views added to a TableRow to display properly until I figured out that I wasn't passing an instance of TableRow.LayoutParams to the child view's setLayoutParams.

The more canonical reference is in <HIToolbox/Events.h>:

/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h

In newer Versions of MacOS the "Events.h" moved to here:

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h

I edited the solution file and changed localhost to my ip address. Before that I had added IIS_IUSRS with full control in the project directory. I can now debug.

Interestingly, when I replaced this:

$("body").trigger("click")

With this:

jQuery("body").trigger("click")

It works!

Update from 2014, from Bootstrap docs:

Grids and full-width layouts Folks looking to create fully fluid layouts (meaning your site stretches the entire width of the viewport) must wrap their grid content in a containing element with padding: 0 15px; to offset the margin: 0 -15px; used on .rows.

Some people seem to turn autoescape off which carries security risks to manipulate the string display.

If you only want to insert some linebreaks into a string and convert the linebreaks into <br />, then you could take a jinja macro like:

{% macro linebreaks_for_string( the_string ) -%}
{% if the_string %}
{% for line in the_string.split('\n') %}
<br />
{{ line }}
{% endfor %}
{% else %}
{{ the_string }}
{% endif %}
{%- endmacro %}

and in your template just call this with

{{ linebreaks_for_string( my_string_in_a_variable ) }}

What do you expect to happen in it's place? The table can't reflow to fill the space left - this seems like a recipe for buggy browser responses.

Think about hiding the contents of the td, not the td itself.

Use System.DateTime.Now.ToUniversalTime(). That puts your reading in a known reference-based millisecond format that totally eliminates day change, etc.

This is an old question but it has a lot of views so I think that is important to update it.

ECMAScript 6 brought the function Math.sign(), which returns the sign of a number (1 if it's positive, -1 if it's negative) or NaN if it is not a number. Reference

You could use it as:

var number = 1;

if(Math.sign(number) === 1){
    alert("I'm positive");
}else if(Math.sign(number) === -1){
    alert("I'm negative");
}else{
    alert("I'm not a number");
}

$("label[for='"+$(this).attr("id")+"']");

This should allow you to select labels for all the fields in a loop as well. All you need to ensure is your labels should say for='FIELD' where FIELD is the id of the field for which this label is being defined.

It sounds like this is referring to something else than you think. In what context are you using it?

The this keyword is usually only used within a callback function of an event-handler, when you loop over a set of elements, or similar. In that context it refers to a particular DOM-element, and can be used the way you do.

If you only want to access that particular button (outside any callback or loop) and don't have any other elements that use the btn-info class, you could do something like:

parseInt($(".btn-info").data('votevalue'), 10);

You could also assign the element an ID, and use that to select on, which is probably a safer way, if you want to be sure that only one element match your selector.

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Basically, you use the /B and /C options:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

As said here and i quote:

just change this line on config.inc.php

$cfg['Servers'][$i]['auth_type'] = 'config'; 

to

$cfg['Servers'][$i]['auth_type'] = 'cookie'; 

then you will be prompted to login when you refreshed the page. Afterwards, the log out icon will appear next to home icon.

Since in your question you said it's a PHP script, maybe the best solution could be to simply add in your script:

ignore_user_abort(TRUE);

In this way even if wget terminates, the PHP script goes on being processed at least until it does not exceeds max_execution_time limit (ini directive: 30 seconds by default).

As per wget anyay you should not change its timeout, according to the UNIX manual the default wget timeout is 900 seconds (15 minutes), whis is much larger that the 5-6 minutes you need.

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

There are two typical ways of declaring a function. I prefer the second approach.

function function_name {
   command...
} 

or

function_name () {
   command...
} 

To call a function with arguments:

function_name "$arg1" "$arg2"

The function refers to passed arguments by their position (not by name), that is $1, $2, and so forth. $0 is the name of the script itself.

Example:

function_name () {
   echo "Parameter #1 is $1"
}

Also, you need to call your function after it is declared.

#!/usr/bin/env sh

foo 1  # this will fail because foo has not been declared yet.

foo() {
    echo "Parameter #1 is $1"
}

foo 2 # this will work.

Output:

./myScript.sh: line 2: foo: command not found
Parameter #1 is 2

If you happen to be working with a application which has a mix of Windows Forms and WPF you might have the additional complication of trying to convert a System.Drawing.Color to a System.Windows.Media.Color. I'm not sure if there is an easier way to do this, but I did it this way:

System.Drawing.Color MyColor = System.Drawing.Color.Red;
System.Windows.Media.Color = ConvertColorType(MyColor);

System.Windows.Media.Color ConvertColorType(System.Drawing.Color color)
{
  byte AVal = color.A;
  byte RVal = color.R;
  byte GVal = color.G;
  byte BVal = color.B;

  return System.Media.Color.FromArgb(AVal, RVal, GVal, BVal);
}

Then you can use one of the techniques mentioned previously to convert to a Brush.

From the Documentation

As with components, you can add as many directive property bindings as you need by stringing them along in the template.

Add an input property to HighlightDirective called defaultColor:

@Input() defaultColor: string;

Markup

<p [myHighlight]="color" defaultColor="violet">
  Highlight me too!
</p>

Angular knows that the defaultColor binding belongs to the HighlightDirective because you made it public with the @Input decorator.

Either way, the @Input decorator tells Angular that this property is public and available for binding by a parent component. Without @Input, Angular refuses to bind to the property.

For your example

With many parameters

Add properties into the Directive class with @Input() decorator

@Directive({
    selector: '[selectable]'
})
export class SelectableDirective{
    private el: HTMLElement;

    @Input('selectable') option:any;   
    @Input('first') f;
    @Input('second') s;

    ...
}

And in the template pass bound properties to your li element

<li *ngFor = 'let opt of currentQuestion.options' 
    [selectable] = 'opt' 
    [first]='YourParameterHere'
    [second]='YourParameterHere'
    (selectedOption) = 'onOptionSelection($event)'>
    {{opt.option}}
</li>

Here on the li element we have a directive with name selectable. In the selectable we have two @Input()'s, f with name first and s with name second. We have applied these two on the li properties with name [first] and [second]. And our directive will find these properties on that li element, which are set for him with @Input() decorator. So selectable, [first] and [second] will be bound to every directive on li, which has property with these names.

With single parameter

@Directive({
    selector: '[selectable]'
})
export class SelectableDirective{
    private el: HTMLElement;

    @Input('selectable') option:any;   
    @Input('params') params;

    ...
}

Markup

<li *ngFor = 'let opt of currentQuestion.options' 
    [selectable] = 'opt' 
    [params]='{firstParam: 1, seconParam: 2, thirdParam: 3}'
    (selectedOption) = 'onOptionSelection($event)'>
    {{opt.option}}
</li>

There too some very helpful way.

http://devlicio.us/blogs/sergio_pereira/archive/2009/02/09/javascript-5-ways-to-call-a-function.aspx

var arrayMaker = {  
    someProperty: 'some value here',  
    make: function (arg1, arg2) {  
        return [ this, arg1, arg2 ];  
    },
    execute: function_name
};

For just quickly viewing the cookies on any particular page, I keep a favorites-bar "Cookies" shortcut with the URL set to:

javascript:window.alert(document.cookie.split(';').join(';\r\n'));

Another interesting approach would be to use when:

when(a) {
  true -> b
  false -> c
}

Can be quite handy in some more complex scenarios. And honestly, it's more readable for me than if ... else ...

declare @RangeWidth int

set @RangeWidth = 10

select
   Floor(Score/@RangeWidth) as LowerBound,
   Floor(Score/@RangeWidth)+@RangeWidth as UpperBound,
   Count(*)
From
   ScoreTable
group by
   Floor(Score/@RangeWidth)

If you have a lot of variables to convert in optional, you can use SubimeText with this:

Find: \${([A-Za-z_0-9]*)}
Replace: \$\{${1}!\}

Be sure regex and case-sensitive options are enabled:

I prefer this syntax as it allows to set configuration parameters for the shell:

---
- name: an example
  shell:
    cmd: |
      docker build -t current_dir .
      echo "Hello World"
      date

    chdir: /home/vagrant/

tooltips: {
          callbacks: {
            label: (tooltipItem, data) => {
              // data for manipulation
              return data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index];
            },
          },
        },

You can also use only platform module without importing os module to get all the information.

>>> import platform
>>> platform.os.name
'posix'
>>> platform.uname()
('Darwin', 'mainframe.local', '15.3.0', 'Darwin Kernel Version 15.3.0: Thu Dec 10 18:40:58 PST 2015; root:xnu-3248.30.4~1/RELEASE_X86_64', 'x86_64', 'i386')

A nice and tidy layout for reporting purpose can be achieved using this line:

for i in zip(['system','node','release','version','machine','processor'],platform.uname()):print i[0],':',i[1]

That gives this output:

system : Darwin
node : mainframe.local
release : 15.3.0
version : Darwin Kernel Version 15.3.0: Thu Dec 10 18:40:58 PST 2015; root:xnu-3248.30.4~1/RELEASE_X86_64
machine : x86_64
processor : i386

What is missing usually is the operating system version but you should know if you are running windows, linux or mac a platform indipendent way is to use this test:

In []: for i in [platform.linux_distribution(),platform.mac_ver(),platform.win32_ver()]:
   ....:     if i[0]:
   ....:         print 'Version: ',i[0]
