Just use the function below that returns width and height of the screen size as an array of integers

private int[] getScreenSIze(){
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int h = displaymetrics.heightPixels;
        int w = displaymetrics.widthPixels;

        int[] size={w,h};
        return size;

    }

On your onCreate function or button click add the following code to output the screen sizes as shown below

 int[] screenSize= getScreenSIze();
        int width=screenSize[0];
        int height=screenSize[1];
        screenSizes.setText("Phone Screen sizes \n\n  width = "+width+" \n Height = "+height);

Part A: Configuring your Application Pool

Suppose the Application Pool is named 'MyPool' Go to 'Advanced Settings' of the Application Pool from the IIS Manager

1. Scroll down to 'Identity'. Trying to edit the value will bring up a dialog box. Select 'Built-In account' and under it, select 'ApplicationPoolIdentity'.

2. A few lines below 'Identity', you should find 'Load User Profile'. This value should be set to 'True'.

Part B: Configuring your website

1. Website Name: SiteName (just an example)
2. Physical Path: C:\Whatever (just an example)
3. Connect as... : Application User (pass-through authentication) (The above settings can be found in 'Basic Settings' of the site in the IIS Manager)
4. After configuring the basic settings, look for the 'Authentication' configuration under 'IIS' in the main console of the site. Open it. You should see an option for 'Anonymous Authentication'. Make sure it is enabled. Then right click and 'Edit...' it. Select 'Application Pool Identity'.

Part C: Configuring your folder

The folder in question is C:\Whatever

1. Go to Properties - Sharing - Advanced Sharing - Permissions, and tick 'Share this folder'
2. In the same dialog box, you will find a button 'Permissions'. Click it.
3. A new dialog box will open. Click 'Add'.
4. A new dialog box 'Select Users or Groups' will open. Under 'From this location' make sure the name is the same as your local host computer. Then, under 'Enter the object names', type 'IIS AppPool\MyPool' and click 'Check Names' and then 'Ok'
5. Give full sharing permissions for 'MyPool' user. Apply it and close the folder properties
6. Open folder properties again. This time, go to Security - Advanced - Permission, and click Add. There will be an option 'Select a Principal' at the top, or some other option to choose a user. Click it.
7. The 'Select Users or Groups' dialog box will open again. Repeat step 4.
8. Give all or as many permissions you need to the 'MyPool' user.
9. Check 'Replace all child object permissions..." and Apply and close.

You should now be able to use the browse the website

public static void main(String[] args) {
    String value = " Chlamydia_spp. IgG, IgM & IgA Abs (8006) ";

    System.out.println(value.replaceAll("[^A-Za-z0-9]", ""));

}

output: ChlamydiasppIgGIgMIgAAbs8006

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

You can try this:

NSLog(@"%@", NSStringFromCGPoint(cgPoint));

There are a number of functions provided by UIKit that convert the various CG structs into NSStrings. The reason it doesn't work is because %@ signifies an object. A CGPoint is a C struct (and so are CGRects and CGSizes).

If none of the above work, quotation marks around the stash itself might work for you:

git stash pop "stash@{0}"

Found easiest way for me. Here an example with fork for clarity that this way is useful for flow control.

import signal
import time
import sys
import os

def handle_exit(sig, frame):
    raise(SystemExit)

def main():
    time.sleep(120)

signal.signal(signal.SIGTERM, handle_exit)

p = os.fork()
if p == 0:
    main()
    os._exit()

try:
    os.waitpid(p, 0)
except (KeyboardInterrupt, SystemExit):
    print('exit handled')
    os.kill(p, 15)
    os.waitpid(p, 0)

I think this is the best way:

this.stops.stream().filter(s -> Objects.equals(s.getStation().getName(), this.name)).findFirst().orElse(null);

In httpd.conf add (or change if it's already there):

AddDefaultCharset utf-8

The easiest way I've found for a global association is simply to ctrl+k m (or ctrl+shift+p and type "change language mode") with a file of the type you're associating open.

In the first selections will be "Configure File Association for 'x' " (whatever file type - see image attached) Selecting this makes the filetype association permanent

This may have changed (probably did) since the original question and accepted answer (and I don't know when it changed) but it's so much easier than the manual editing steps in the accepted and some of the other answers, and totaly avoids having to muss with IDs that may not be obvious.

The way to "start" the array that you want is:

arr = np.empty((0,3), int)

Which is an empty array but it has the proper dimensionality.

>>> arr
array([], shape=(0, 3), dtype=int64)

Then be sure to append along axis 0:

arr = np.append(arr, np.array([[1,2,3]]), axis=0)
arr = np.append(arr, np.array([[4,5,6]]), axis=0)

But, @jonrsharpe is right. In fact, if you're going to be appending in a loop, it would be much faster to append to a list as in your first example, then convert to a numpy array at the end, since you're really not using numpy as intended during the loop:

In [210]: %%timeit
   .....: l = []
   .....: for i in xrange(1000):
   .....:     l.append([3*i+1,3*i+2,3*i+3])
   .....: l = np.asarray(l)
   .....: 
1000 loops, best of 3: 1.18 ms per loop

In [211]: %%timeit
   .....: a = np.empty((0,3), int)
   .....: for i in xrange(1000):
   .....:     a = np.append(a, 3*i+np.array([[1,2,3]]), 0)
   .....: 
100 loops, best of 3: 18.5 ms per loop

In [214]: np.allclose(a, l)
Out[214]: True

The numpythonic way to do it depends on your application, but it would be more like:

In [220]: timeit n = np.arange(1,3001).reshape(1000,3)
100000 loops, best of 3: 5.93 µs per loop

In [221]: np.allclose(a, n)
Out[221]: True

Your first option is the good one. It's the least problematic one and you've already found the correct reasons why you couldn't use the other options.

By the way, your heading IS explicitly associated with the <ul> : it's right before the list! ;)

edit: Steve Faulkner, one of the editors of W3C HTML5 and 5.1 has sketched out a definition of an lt element. That's an unofficial draft that he'll discuss for HTML 5.2, nothing more yet.

Don't Create 9-patch images for launcher icons . You have to make separate image for each one.

The main disadvantage of the #define method is that the string is duplicated each time it is used, so you can end up with lots of copies of it in the executable, making it bigger.

In C you can use memcpy. In C++ use std::copy from the <algorithm> header.

I don't understand why I should add a dimension (ie: making the int into an array) since I only need to store a digit as key.

An array is also an Object, so HashMap<int[], MyObject> is a valid construct that uses int arrays as keys.

Compiler doesn't know what you want or what you need, it just sees a language construct that is almost correct, and warns what's missing for it to be fully correct.

You can add a style.css, import this file after the bootstrap.css to override this code.

For example:

/* bootstrap.css */
* {
   font-size: 14px;
   line-height: 1.428;
}

/* style.css */
* {
   font-size: 16px;
   line-height: 2;
}

Don't change bootstrap.css directly for better maintenance of code.

You can use the indexOfmethod and "extend" the Array class with the method contains like this:

Array.prototype.contains = function(element){
    return this.indexOf(element) > -1;
};

with the following results:

["A", "B", "C"].contains("A") equals true

["A", "B", "C"].contains("D") equals false

Guava almost always has what you need.

ThreadFactory namedThreadFactory = 
  new ThreadFactoryBuilder().setNameFormat("my-sad-thread-%d").build()

and pass it off to your ExecutorService.

I had to face this problem too and had a work around which i checked on HTC one, galaxy s1, s2, s3, note and HTC sensation.

put a global layout listener on the root view of your layout

mRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener(){
            public void onGlobalLayout() {
                checkHeightDifference();
            }
    });

and in there i checked the height difference and if the height difference of the screen is bigger then a third on the screen height then we can assume the keyboard is open. took it from this answer.

private void checkHeightDifference(){
    // get screen frame rectangle 
    Rect r = new Rect();
    mRootView.getWindowVisibleDisplayFrame(r);
    // get screen height
    int screenHeight = mRootView.getRootView().getHeight();
    // calculate the height difference
    int heightDifference = screenHeight - (r.bottom - r.top);

    // if height difference is different then the last height difference and
    // is bigger then a third of the screen we can assume the keyboard is open
    if (heightDifference > screenHeight/3 && heightDifference != mLastHeightDifferece) {
        // keyboard visiblevisible
        // get root view layout params
        FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
        // set the root view height to screen height minus the height difference
        lp.height = screenHeight - heightDifference;
        // call request layout so the changes will take affect
        .requestLayout();
        // save the height difference so we will run this code only when a change occurs.
        mLastHeightDifferece = heightDifference;
    } else if (heightDifference != mLastHeightDifferece) {
        // keyboard hidden
        PFLog.d("[ChatroomActivity] checkHeightDifference keyboard hidden");
        // get root view layout params and reset all the changes we have made when the keyboard opened.
        FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
        lp.height = screenHeight;
        // call request layout so the changes will take affect
        mRootView.requestLayout();
        // save the height difference so we will run this code only when a change occurs.
        mLastHeightDifferece = heightDifference;
    }
}

this is probably not bullet proof and maybe on some devices it will not work but it worked for me and hope it will help you too.

SELECT  *
FROM    (
        SELECT  q.*, rownum rn
        FROM    (
                SELECT  *
                FROM    maps006
                ORDER BY
                        id
                ) q
        )
WHERE   rn BETWEEN 50 AND 100

Note the double nested view. ROWNUM is evaluated before ORDER BY, so it is required for correct numbering.

If you omit ORDER BY clause, you won't get consistent order.

I found the correct solution you can use this code

$('.close').click(); 

This error can also be thrown through missing write permissions on the repository.

My concrete case went like this:

1. I created a repo with the root user of my server (via SSH).
2. I installed a git service and created a git linux user that should manage all git-related action.
3. By that time, I had forgotten that the repo was created with the root user in the first place, and the git user simply didn't have the file permissions to write anything into the repository.

this function gets a dict, and another dict specifying how to rename keys; it returns a new dict, with renamed keys:

def rekey(inp_dict, keys_replace):
    return {keys_replace.get(k, k): v for k, v in inp_dict.items()}

test:

def test_rekey():
    assert rekey({'a': 1, "b": 2, "c": 3}, {"b": "beta"}) == {'a': 1, "beta": 2, "c": 3}

I got the same problem after upgrading java from 1.8.0_202 to 1.8.0_211

Problem:

Here are directories where new version of 1.8.0_211 of Java installed:

Directory of c:\Program Files\Java\jre1.8.0_211\bin Directory of c:\Program Files (x86)\Common Files\Oracle\Java\javapath

So one is located in 32 bit and second is in 64 bit Program files folder. The one that is specified in the PATH is 32 bit version (c:\Program Files (x86)\Common Files\Oracle\Java\javapath), even though it was 64 bit version of the Java that was installed.

Solution:

Change system environments variable PATH from c:\Program Files (x86)\Common Files\Oracle\Java\javapath to c:\Program Files\Java\jre1.8.0_211\bin

There is _tkinter and Tkinter - both work on Py 3.x But to be safe- Download Loopy and change your python root directory(if you're using an IDE like PyCharms) to Loopy's installation directory. You'll get this library and many more.

ASP.NET MVC View Engines (Community Wiki)

Since a comprehensive list does not appear to exist, let's start one here on SO. This can be of great value to the ASP.NET MVC community if people add their experience (esp. anyone who contributed to one of these). Anything implementing IViewEngine (e.g. VirtualPathProviderViewEngine) is fair game here. Just alphabetize new View Engines (leaving WebFormViewEngine and Razor at the top), and try to be objective in comparisons.

System.Web.Mvc.WebFormViewEngine

Design Goals:

A view engine that is used to render a Web Forms page to the response.

Pros:

• ubiquitous since it ships with ASP.NET MVC
• familiar experience for ASP.NET developers
• IntelliSense
• can choose any language with a CodeDom provider (e.g. C#, VB.NET, F#, Boo, Nemerle)
• on-demand compilation or precompiled views

Cons:

• usage is confused by existence of "classic ASP.NET" patterns which no longer apply in MVC (e.g. ViewState PostBack)
• can contribute to anti-pattern of "tag soup"
• code-block syntax and strong-typing can get in the way
• IntelliSense enforces style not always appropriate for inline code blocks
• can be noisy when designing simple templates

Example:

<%@ Control Inherits="System.Web.Mvc.ViewPage<IEnumerable<Product>>" %>
<% if(model.Any()) { %>
<ul>
    <% foreach(var p in model){%>
    <li><%=p.Name%></li>
    <%}%>
</ul>
<%}else{%>
    <p>No products available</p>
<%}%>

System.Web.Razor

Design Goals:

Pros:

• Compact, Expressive, and Fluid
• Easy to Learn
• Is not a new language
• Has great Intellisense
• Unit Testable
• Ubiquitous, ships with ASP.NET MVC

Cons:

• Creates a slightly different problem from "tag soup" referenced above. Where the server tags actually provide structure around server and non-server code, Razor confuses HTML and server code, making pure HTML or JS development challenging (see Con Example #1) as you end up having to "escape" HTML and / or JavaScript tags under certain very common conditions.
• Poor encapsulation+reuseability: It's impractical to call a razor template as if it were a normal method - in practice razor can call code but not vice versa, which can encourage mixing of code and presentation.
• Syntax is very html-oriented; generating non-html content can be tricky. Despite this, razor's data model is essentially just string-concatenation, so syntax and nesting errors are neither statically nor dynamically detected, though VS.NET design-time help mitigates this somewhat. Maintainability and refactorability can suffer due to this.
• No documented API, http://msdn.microsoft.com/en-us/library/system.web.razor.aspx

Con Example #1 (notice the placement of "string[]..."):

@{
    <h3>Team Members</h3> string[] teamMembers = {"Matt", "Joanne", "Robert"};
    foreach (var person in teamMembers)
    {
        <p>@person</p>
    }
}

Bellevue

Design goals:

• Respect HTML as first-class language as opposed to treating it as "just text".
• Don't mess with my HTML! The data binding code (Bellevue code) should be separate from HTML.
• Enforce strict Model-View separation

Brail

Design Goals:

The Brail view engine has been ported from MonoRail to work with the Microsoft ASP.NET MVC Framework. For an introduction to Brail, see the documentation on the Castle project website.

Pros:

• modeled after "wrist-friendly python syntax"
• On-demand compiled views (but no precompilation available)

Cons:

• designed to be written in the language Boo

Example:

<html>    
<head>        
<title>${title}</title>
</head>    
<body>        
     <p>The following items are in the list:</p>  
     <ul><%for element in list:    output "<li>${element}</li>"%></ul>
     <p>I hope that you would like Brail</p>    
</body>
</html>

Hasic

Hasic uses VB.NET's XML literals instead of strings like most other view engines.

Pros:

• Compile-time checking of valid XML
• Syntax colouring
• Full intellisense
• Compiled views
• Extensibility using regular CLR classes, functions, etc
• Seamless composability and manipulation since it's regular VB.NET code
• Unit testable

Cons:

• Performance: Builds the whole DOM before sending it to client.

Example:

Protected Overrides Function Body() As XElement
    Return _
    <body>
        <h1>Hello, World</h1>
    </body>
End Function

NDjango

Design Goals:

NDjango is an implementation of the Django Template Language on the .NET platform, using the F# language.

Pros:

• NDjango release 0.9.1.0 seems to be more stable under stress than WebFormViewEngine
• Django Template Editor with syntax colorization, code completion, and as-you-type diagnostics (VS2010 only)
• Integrated with ASP.NET, Castle MonoRail and Bistro MVC frameworks

NHaml

Design Goals:

.NET port of Rails Haml view engine. From the Haml website:

Haml is a markup language that's used to cleanly and simply describe the XHTML of any web document, without the use of inline code... Haml avoids the need for explicitly coding XHTML into the template, because it is actually an abstract description of the XHTML, with some code to generate dynamic content.

Pros:

• terse structure (i.e. D.R.Y.)
• well indented
• clear structure
• C# Intellisense (for VS2008 without ReSharper)

Cons:

• an abstraction from XHTML rather than leveraging familiarity of the markup
• No Intellisense for VS2010

Example:

@type=IEnumerable<Product>
- if(model.Any())
  %ul
    - foreach (var p in model)
      %li= p.Name
- else
  %p No products available

NVelocityViewEngine (MvcContrib)

Design Goals:

A view engine based upon NVelocity which is a .NET port of the popular Java project Velocity.

Pros:

• easy to read/write
• concise view code

Cons:

• limited number of helper methods available on the view
• does not automatically have Visual Studio integration (IntelliSense, compile-time checking of views, or refactoring)

Example:

#foreach ($p in $viewdata.Model)
#beforeall
    <ul>
#each
    <li>$p.Name</li>
#afterall
    </ul>
#nodata 
    <p>No products available</p>
#end

SharpTiles

Design Goals:

SharpTiles is a partial port of JSTL combined with concept behind the Tiles framework (as of Mile stone 1).

Pros:

• familiar to Java developers
• XML-style code blocks

Cons:

• ...

Example:

<c:if test="${not fn:empty(Page.Tiles)}">
  <p class="note">
    <fmt:message key="page.tilesSupport"/>
  </p>
</c:if>

Spark View Engine

Design Goals:

The idea is to allow the html to dominate the flow and the code to fit seamlessly.

Pros:

• Produces more readable templates
• C# Intellisense (for VS2008 without ReSharper)
• SparkSense plug-in for VS2010 (works with ReSharper)
• Provides a powerful Bindings feature to get rid of all code in your views and allows you to easily invent your own HTML tags

Cons:

• No clear separation of template logic from literal markup (this can be mitigated by namespace prefixes)

Example:

<viewdata products="IEnumerable[[Product]]"/>
<ul if="products.Any()">
    <li each="var p in products">${p.Name}</li>
</ul>
<else>
    <p>No products available</p>
</else>

<Form style="background-color:olive;">
    <Label For="username" />
    <TextBox For="username" />
    <ValidationMessage For="username" Message="Please type a valid username." />
</Form>

StringTemplate View Engine MVC

Design Goals:

• Lightweight. No page classes are created.
• Fast. Templates are written to the Response Output stream.
• Cached. Templates are cached, but utilize a FileSystemWatcher to detect file changes.
• Dynamic. Templates can be generated on the fly in code.
• Flexible. Templates can be nested to any level.
• In line with MVC principles. Promotes separation of UI and Business Logic. All data is created ahead of time, and passed down to the template.

Pros:

• familiar to StringTemplate Java developers

Cons:

• simplistic template syntax can interfere with intended output (e.g. jQuery conflict)

Wing Beats

Wing Beats is an internal DSL for creating XHTML. It is based on F# and includes an ASP.NET MVC view engine, but can also be used solely for its capability of creating XHTML.

Pros:

• Compile-time checking of valid XML
• Syntax colouring
• Full intellisense
• Compiled views
• Extensibility using regular CLR classes, functions, etc
• Seamless composability and manipulation since it's regular F# code
• Unit testable

Cons:

• You don't really write HTML but code that represents HTML in a DSL.

XsltViewEngine (MvcContrib)

Design Goals:

Builds views from familiar XSLT

Pros:

• widely ubiquitous
• familiar template language for XML developers
• XML-based
• time-tested
• Syntax and element nesting errors can be statically detected.

Cons:

• functional language style makes flow control difficult
• XSLT 2.0 is (probably?) not supported. (XSLT 1.0 is much less practical).

Since the question of multiple inheritance (MI) pops up from time to time, I'd like to add an approach which addresses some problems with the composition pattern.

I build upon the IFirst, ISecond,First, Second, FirstAndSecond approach, as it was presented in the question. I reduce sample code to IFirst, since the pattern stays the same regardless of the number of interfaces / MI base classes.

Lets assume, that with MI First and Second would both derive from the same base class BaseClass, using only public interface elements from BaseClass

This can be expressed, by adding a container reference to BaseClass in the First and Second implementation:

class First : IFirst {
  private BaseClass ContainerInstance;
  First(BaseClass container) { ContainerInstance = container; }
  public void FirstMethod() { Console.WriteLine("First"); ContainerInstance.DoStuff(); } 
}
...

Things become more complicated, when protected interface elements from BaseClass are referenced or when First and Second would be abstract classes in MI, requiring their subclasses to implement some abstract parts.

class BaseClass {
  protected void DoStuff();
}

abstract class First : IFirst {
  public void FirstMethod() { DoStuff(); DoSubClassStuff(); }
  protected abstract void DoStuff(); // base class reference in MI
  protected abstract void DoSubClassStuff(); // sub class responsibility
}

C# allows nested classes to access protected/private elements of their containing classes, so this can be used to link the abstract bits from the First implementation.

class FirstAndSecond : BaseClass, IFirst, ISecond {
  // link interface
  private class PartFirst : First {
    private FirstAndSecond ContainerInstance;
    public PartFirst(FirstAndSecond container) {
      ContainerInstance = container;
    }
    // forwarded references to emulate access as it would be with MI
    protected override void DoStuff() { ContainerInstance.DoStuff(); }
    protected override void DoSubClassStuff() { ContainerInstance.DoSubClassStuff(); }
  }
  private IFirst partFirstInstance; // composition object
  public FirstMethod() { partFirstInstance.FirstMethod(); } // forwarded implementation
  public FirstAndSecond() {
    partFirstInstance = new PartFirst(this); // composition in constructor
  }
  // same stuff for Second
  //...
  // implementation of DoSubClassStuff
  private void DoSubClassStuff() { Console.WriteLine("Private method accessed"); }
}

There is quite some boilerplate involved, but if the actual implementation of FirstMethod and SecondMethod are sufficiently complex and the amount of accessed private/protected methods is moderate, then this pattern may help to overcome lacking multiple inheritance.

Simply create an object of Base64 and use it to encode or decode, when using org.apache.commons.codec.binary.Base64 library

To Encode

Base64 ed=new Base64();

String encoded=new String(ed.encode("Hello".getBytes()));

Replace "Hello" with the text to be encoded in String Format.

To Decode

Base64 ed=new Base64();

String decoded=new String(ed.decode(encoded.getBytes()));

Here encoded is the String variable to be decoded

mycollection.find_one_and_update({"_id": mongo_id}, 
                                 {"$set": {"newfield": "abc"}})

should work splendidly for you. If there is no document of id mongo_id, it will fail, unless you also use upsert=True. This returns the old document by default. To get the new one, pass return_document=ReturnDocument.AFTER. All parameters are described in the API.

The method was introduced for MongoDB 3.0. It was extended for 3.2, 3.4, and 3.6.

Another take for those of you that enjoy succinct code.

NOTE: The FILTER method can take an additional this argument, then using an E6 arrow function we can reuse the correct this to get a nice one-liner.

Try the --force option. svn help checkout gives the details.

Import namespace :

using System.Configuration;

Create ConfigurationElement Company :

public class Company : ConfigurationElement
{

        [ConfigurationProperty("name", IsRequired = true)]
        public string Name
        {
            get
            {
                return this["name"] as string;
            }
        }
            [ConfigurationProperty("code", IsRequired = true)]
        public string Code
        {
            get
            {
                return this["code"] as string;
            }
        }
}

ConfigurationElementCollection:

public class Companies
        : ConfigurationElementCollection
    {
        public Company this[int index]
        {
            get
            {
                return base.BaseGet(index) as Company ;
            }
            set
            {
                if (base.BaseGet(index) != null)
                {
                    base.BaseRemoveAt(index);
                }
                this.BaseAdd(index, value);
            }
        }

       public new Company this[string responseString]
       {
            get { return (Company) BaseGet(responseString); }
            set
            {
                if(BaseGet(responseString) != null)
                {
                    BaseRemoveAt(BaseIndexOf(BaseGet(responseString)));
                }
                BaseAdd(value);
            }
        }

        protected override System.Configuration.ConfigurationElement CreateNewElement()
        {
            return new Company();
        }

        protected override object GetElementKey(System.Configuration.ConfigurationElement element)
        {
            return ((Company)element).Name;
        }
    }

and ConfigurationSection:

public class RegisterCompaniesConfig
        : ConfigurationSection
    {

        public static RegisterCompaniesConfig GetConfig()
        {
            return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig();
        }

        [System.Configuration.ConfigurationProperty("Companies")]
            [ConfigurationCollection(typeof(Companies), AddItemName = "Company")]
        public Companies Companies
        {
            get
            {
                object o = this["Companies"];
                return o as Companies ;
            }
        }

    }

and you must also register your new configuration section in web.config (app.config):

<configuration>       
    <configSections>
          <section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>

then you load your config with

var config = RegisterCompaniesConfig.GetConfig();
foreach(var item in config.Companies)
{
   do something ..
}

I'd prefer not to use an HTML5 only element such as <section>. Also grouping the input fields might painful if you try to generate the form with code. It's always better to produce similar markup for each one and only change the class names. Therefore I would recommend a solution that looks like this :

CSS

label, input {
    display: block;
}
ul.form {
    width  : 500px;
    padding: 0px;
    margin : 0px;
    list-style-type: none;
}
ul.form li  {
    width : 500px;
}
ul.form li input {
    width : 200px;
}
ul.form li textarea {
    width : 450px;
    height: 150px;
}
ul.form li.twoColumnPart {
    float : left;
    width : 250px;
}

HTML

<form name="message" method="post">
    <ul class="form">
        <li class="twoColumnPart">
            <label for="name">Name</label>
            <input id="name" type="text" value="" name="name">
        </li>
        <li class="twoColumnPart">
            <label for="email">Email</label>
            <input id="email" type="text" value="" name="email">
        </li>
        <li>
            <label for="subject">Subject</label>
            <input id="subject" type="text" value="" name="subject">
        </li>
        <li>
            <label for="message">Message</label>
            <textarea id="message" type="text" name="message"></textarea>
        </li>
    </ul>
</form>

You have a number of options:

One is to not use streams, but use the TextWriter

   void Print(TextWriter writer) 
   {
   }

   void Main() 
  {
    var textWriter = new StringWriter();
    Print(writer);
    string myString = textWriter.ToString();
   }

It's likely that TextWriter is the appropriate level of abstraction for your print function. Streams are aimed at writing binary data, while TextWriter works at a higher abstraction level, specifically geared towards outputting strings.

If your motivation is that you also want your Print function to write to files, you can get a text writer from a filestream as well.

void Print(TextWriter writer) 
{
}

void PrintToFile(string filePath) 
{
     using(var textWriter = new StreamWriter(filePath))
     {
         Print(writer);
     }
}

If you REALLY want a stream you can look at MemoryStream.

How about:

SELECT * FROM sometable WHERE CHAR_LENGTH(LINK) > 1

Here's the MySql string functions page (5.0).

Note that I chose CHAR_LENGTH instead of LENGTH, as if there are multibyte characters in the data you're probably really interested in how many characters there are, not how many bytes of storage they take. So for the above, a row where LINK is a single two-byte character wouldn't be returned - whereas it would when using LENGTH.

Note that if LINK is NULL, the result of CHAR_LENGTH(LINK) will be NULL as well, so the row won't match.

select *  
from dbo.March2010 A 
where A.Date >= Convert(datetime, '2010-04-01' )

In your query, 2010-4-01 is treated as a mathematical expression, so in essence it read

select *  
from dbo.March2010 A 
where A.Date >= 2005; 

(2010 minus 4 minus 1 is 2005 Converting it to a proper datetime, and using single quotes will fix this issue.)

Technically, the parser might allow you to get away with

select *  
from dbo.March2010 A 
where A.Date >= '2010-04-01'

it will do the conversion for you, but in my opinion it is less readable than explicitly converting to a DateTime for the maintenance programmer that will come after you.

For completeness, if you wanted to use replaceFirst, try this:

public static String cap1stChar(String userIdea)
{
  String betterIdea = userIdea;
  if (userIdea.length() > 0)
  {
    String first = userIdea.substring(0,1);
    betterIdea = userIdea.replaceFirst(first, first.toUpperCase());
  }
  return betterIdea;
}//end cap1stChar

You have to take whole columns under resizebox. This code worked for me

\begin{table}[htbp]
\caption{Sample Table.}\label{tab1}
\resizebox{\columnwidth}{!}{\begin{tabular}{|l|l|l|l|l|}
\hline
URL &  First Time Visit & Last Time Visit & URL Counts & Value\\
\hline
https://web.facebook.com/ & 1521241972 & 1522351859 & 177 & 56640\\
http://localhost/phpmyadmin/ & 1518413861 & 1522075694 & 24 & 39312\\
https://mail.google.com/mail/u/ & 1516596003 & 1522352010 & 36 & 33264\\

\hline
\end{tabular}}
\end{table}

Simple, ORDER BY orders the data and GROUP BY groups, or combines the data.

ORDER BY orders the result set as per the mentioned field, by default in ascending order.

Suppose you are firing a query as ORDER BY (student_roll_number), it will show you result in ascending order of student's roll numbers. Here, student_roll_number entry might occur more than once.

In GROUP BY case, we use this with aggregate functions, and it groups the data as per the aggregate function, and we get the result. Here, if our query has SUM (marks) along with GROUP BY (student_first_name) it will show the sum of marks of students belonging to each group (where all members of a group will have the same first name).

My problem was int Main() instead of int main()

good luck

You can only set the connection timeout on the connection string, the timeout for your query would normally be on the command timeout. (Assuming we are talking .net here, I can't really tell from your question).

However the command timeout has no effect when the command is executed against a context connection (a SqlConnection opened with "context connection=true" in the connection string).

No , Both are different . Composition follow "HAS-A" relationship and inheritance follow "IS-A" relationship . Best Example for composition was Strategic pattern .

Well you can simply use this piece of code in your scss file; This will remove that unwanted color change,

a:-webkit-any-link {
  &:hover {
    color: white;
  }
}

Giphy Gotcha

After following the 2 requirements listed above (must end in .gif and using the image syntax), if you are having trouble with a gif from giphy:

Be sure you have the correct giphy url! You can't just add .gif to the end of this one and have it work.

If you just copy the url from a browser, you will get something like:

https://giphy.com/gifs/gol-automaton-game-of-life-QfsvYoBSSpfbtFJIVo

You need to instead click on "Copy Link" and then grab the "GIF Link" specifically. Notice the correct one points to media.giphy.com instead of just giphy.com:

https://media.giphy.com/media/QfsvYoBSSpfbtFJIVo/giphy.gif

save() can take a file-like object as well as a path, so you can use an in-memory buffer like a StringIO:

buf = StringIO.StringIO()
im.save(buf, format='JPEG')
jpeg = buf.getvalue()

Try this below code for binding html through attr

.directive('dynamic', function ($compile) {
    return {
      restrict: 'A',
      replace: true,
      scope: { dynamic: '=dynamic'},
      link: function postLink(scope, element, attrs) {
        scope.$watch( 'attrs.dynamic' , function(html){
          element.html(scope.dynamic);
          $compile(element.contents())(scope);
        });
      }
    };
  });

Try this element.html(scope.dynamic); than element.html(attr.dynamic);

Strictly speaking, you should put something that makes sense - according to the spec here, the most correct version is:

<input name=name id=id type=checkbox checked=checked>

For HTML, you can also use the empty attribute syntax, checked="", or even simply checked (for stricter XHTML, this is not supported).

Effectively, however, most browsers will support just about any value between the quotes. All of the following will be checked:

<input name=name id=id type=checkbox checked>
<input name=name id=id type=checkbox checked="">
<input name=name id=id type=checkbox checked="yes">
<input name=name id=id type=checkbox checked="blue">
<input name=name id=id type=checkbox checked="false">

And only the following will be unchecked:

<input name=name id=id type=checkbox>

Kotlin standard lib doesn't provide Random Number Generator API. If you aren't in a multiplatform project, it's better to use the platform api (all the others answers of the question talk about this solution).

But if you are in a multiplatform context, the best solution is to implement random by yourself in pure kotlin for share the same random number generator between platforms. It's more simple for dev and testing.

To answer to this problem in my personal project, i implement a pure Kotlin Linear Congruential Generator. LCG is the algorithm used by java.util.Random. Follow this link if you want to use it : https://gist.github.com/11e5ddb567786af0ed1ae4d7f57441d4

My implementation purpose nextInt(range: IntRange) for you ;).

Take care about my purpose, LCG is good for most of the use cases (simulation, games, etc...) but is not suitable for cryptographically usage because of the predictability of this method.

You'll probably have to grant 'localhost' privileges to on the table to the user. See the 'GRANT' syntax documentation. Here's an example (from some C source).

"GRANT ALL PRIVILEGES ON %s.* TO '%s'@'localhost' IDENTIFIED BY '%s'";

That's the most common access problem with MySQL.

Other than that, you might check that the user you have defined to create your instance has full privileges, else the user cannot grant privileges.

Also, make sure the mysql service is started.

Make sure you don't have a third party firewall or Internet security service turned on.

Beyond that, there's several pages of the MySQL forum devoted to this: http://forums.mysql.com/read.php?11,9293,9609#msg-9609

Try reading that.

'make' is a command for UNIX/Linux. Instead of it, use 'nmake' command in MS Windows. Or you'd better use an emulator like CYGWIN.

Use a semicolon

OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";

let heightInPoints = image.size.height
let heightInPixels = heightInPoints * image.scale

let widthInPoints = image.size.width
let widthInPixels = widthInPoints * image.scale

Try using RUN /bin/sh instead of bash.

Add type="text/babel" to the script that includes the .jsx file and add this: <script src="https://npmcdn.com/[email protected]/browser.min.js"></script>

i had same problem but in my case firewall was blocking java directory path, make sure system firewall is allowing java directory path access.

For others who may need this, here's an answer.

Use adb shell dumpsys alarm

You can know the alarm has been set and when are they going to alarmed and interval. Also how many times this alarm has been invoked.

Actually, using ZSH allows you to use special mapping of environment variables. So you can simply do:

# append
path+=('/home/david/pear/bin')
# or prepend
path=('/home/david/pear/bin' $path)
# export to sub-processes (make it inherited by child processes)
export PATH

For me that's a very neat feature which can be propagated to other variables. Example:

typeset -T LD_LIBRARY_PATH ld_library_path :

In eclipse help documentation, we can all icons information as follows. Common path for all eclipse versions except eclipse version:

https://help.eclipse.org/2019-09/index.jsp?nav=%2F1

I had a different experience loading SQL Server 2005 Express on Windows 8. I was using the installer that already had SP4 applied so maybe that explains the difference. The first error I received was when Setup tried to start the SQL VSS Writer. I just told it to Ignore and it continued. I then ran into the same error Sohail had where the SQL Server service failed to start. There was no point in following the rest of Sohail's method since I already was using a SP4 version of SQLServr.exe and SQLOS.dll. Instead, I just canceled the install rebooted the machine and ran the install again. Everything ran fine the second time around.

The place I found Sohail's technique invaluable was when I needed to install SQL Server 2005 Standard on Windows Server 2012. We have a few new servers we're looking to roll out with Windows 2012 but we didn't feel the need to upgrade SQL Server since the 2005 version has all the functionality we need and the cost to license SQL 2012 on these boxes would have been a 5-figure sum.

I wound up tweaking Sohail's technique a bit by adding steps to revert the SQLServr.exe and SQLOS.dll files so that I could then apply SP4 fully. Below are all the steps I took starting from a scratch install of Windows Server 2012 Standard. I hope this helps anyone else looking to get a fully updated install of SQL Server 2005 x64 on this OS.

1. Use Server Manger Add roles and features wizard to satisfy all of SQL's prerequisites:
   • Select the Web Server (IIS) Role
   • Add the following additional Web Server Role Services (note that some of these will automatically pull in others, just accept and move on):
     • HTTP Redirection
     • Windows Authentication
     • ASP.NET 3.5 (note that you'll need to tell the wizard to look in the \Sources\SxS folder of the Windows 2012 installation media for this to install properly; just click the link to "Specify an alternate source path" before clicking Install)
     • IIS 6 Metabase Compatibility
     • IIS 6 WMI Compatibility
2. Start SQL Server 2005 Install, ignoring any compatibility warnings
   • If SQL Server service fails to start during setup, leave dialog up and do the following:
     • Backup SQLServr.exe and SQLOS.dll from C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn
     • Replace those two files from a working copy of SQL Server 2005 that already has had SP4 applied
     • Return to setup, hit Retry and setup will now run to completion.
     • Stop SQL Service and restore orignal versions of SQLServr.exe and SQLOS.dll (or else SP4 doesn't think it is needed in the next step)
3. Install SQL Server 2005 SP4
4. Install SQL Server 2005 SP4 Cumulative Hotfix 5069 (Windows Update wasn't offering this for some reason so I had to download and install manually)
5. If you want the latest documentation, install the latest version of SQL Server 2005 Books Online.

Update (as of Jan. 2018) for App Icon requirements:

https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/app-icon/

Keep icon corners square. The system applies a mask that rounds icon corners automatically.

Keep the background simple and avoid transparency. Make sure your icon is opaque, and don’t clutter the background. Give it a simple background so it doesn’t overpower other app icons nearby. You don’t need to fill the entire icon with content.

There is no advantage of using one vs the other, but, there is a specific case where throw won't work. However, those cases can be fixed.

Any time you are inside of a promise callback, you can use throw. However, if you're in any other asynchronous callback, you must use reject.

For example, this won't trigger the catch:

new Promise(function() {
  setTimeout(function() {
    throw 'or nah';
    // return Promise.reject('or nah'); also won't work
  }, 1000);
}).catch(function(e) {
  console.log(e); // doesn't happen
});

Instead you're left with an unresolved promise and an uncaught exception. That is a case where you would want to instead use reject. However, you could fix this in two ways.

1. by using the original Promise's reject function inside the timeout:

new Promise(function(resolve, reject) {
  setTimeout(function() {
    reject('or nah');
  }, 1000);
}).catch(function(e) {
  console.log(e); // works!
});

2. by promisifying the timeout:

function timeout(duration) { // Thanks joews
  return new Promise(function(resolve) {
    setTimeout(resolve, duration);
  });
}

timeout(1000).then(function() {
  throw 'worky!';
  // return Promise.reject('worky'); also works
}).catch(function(e) {
  console.log(e); // 'worky!'
});

Yes: replace_all is one of the boost string algorithms:

Although it's not a standard library, it has a few things on the standard library:

1. More natural notation based on ranges rather than iterator pairs. This is nice because you can nest string manipulations (e.g., replace_all nested inside a trim). That's a bit more involved for the standard library functions.
2. Completeness. This isn't hard to be 'better' at; the standard library is fairly spartan. For example, the boost string algorithms give you explicit control over how string manipulations are performed (i.e., in place or through a copy).

I was debugging an SSL issue today which resulted in the same write:errno=104 error. Eventually I found out that the reason for this behaviour was that the server required SNI (servername TLS extensions) to work correctly. Supplying the -servername option to openssl made it connect successfully:

openssl s_client -connect domain.tld:443 -servername domain.tld

Hope this helps.

First, I add the references to my Model, then I use them in my code. There are two references you should add:

using System.ServiceModel;
using System.Runtime.Serialization;

then, this problem was solved in my program. I hope this answer can help you. Thanks.

I have following the accepted answer by m.kocikowski and modified is slightly to make use of an autoreleasepool to cleanup all of the temporary strings that are created by stringByReplacingCharactersInRange

In the comment for this method it states, /* Replace characters in range with the specified string, returning new string. */

So, depending on the length of your XML you may be creating a huge pile of new autorelease strings which are not cleaned up until the end of the next @autoreleasepool. If you are unsure when that may happen or if a user action could repeatedly trigger many calls to this method before then you can just wrap this up in an @autoreleasepool. These can even be nested and used within loops where possible.

Apple's reference on @autoreleasepool states this... "If you write a loop that creates many temporary objects. You may use an autorelease pool block inside the loop to dispose of those objects before the next iteration. Using an autorelease pool block in the loop helps to reduce the maximum memory footprint of the application." I have not used it in the loop, but at least this method cleans up after itself now.

- (NSString *) stringByStrippingHTML {
    NSString *retVal;
    @autoreleasepool {
        NSRange r;
        NSString *s = [[self copy] autorelease];
        while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound) {
            s = [s stringByReplacingCharactersInRange:r withString:@""];
        }
        retVal = [s copy];
    } 
    // pool is drained, release s and all temp 
    // strings created by stringByReplacingCharactersInRange
    return retVal;
}

If you just want to find out if an element is contained in the list or not:

>>> li
['a', 'b', 'new', 'mpilgrim', 'z', 'example', 'new', 'two', 'elements']
>>> 'example' in li
True
>>> 'damn' in li
False

Well, those features are specific to a tool that you are using for development in those languages.

You wouldn't have those tools if (for example) you were using notepad to write code. So, maybe you should ask the question for the tool you are using.

For PHP: http://webservices.xml.com/pub/a/ws/2004/03/24/phpws.html

Consider making your route:

_files_manage:
    pattern: /files/management/{project}/{user}
    defaults: { _controller: AcmeTestBundle:File:manage }

since they are required fields. It will make your url's prettier, and be a bit easier to manage.

Your Controller would then look like

 public function projectAction($project, $user)

try xctool, it is a replacement for Apple's xcodebuild that makes it easier to build and test iOS and Mac products. It's especially helpful for continuous integration. It has a few extra features:

1. Runs the same tests as Xcode.app.
2. Structured output of build and test results.
3. Human-friendly, ANSI-colored output.

No.3 is extremely useful. I don't if anyone can read the console output of xcodebuild, I can't, usually it gave me one line with 5000+ characters. Even harder to read than a thesis paper.

I declared class B inside class A, how do I access it?

Just because you declare your struct B inside class A does not mean that an instance of class A automatically has the properties of struct B as members, nor does it mean that it automatically has an instance of struct B as a member.

There is no true relation between the two classes (A and B), besides scoping.

struct A { 
  struct B { 
    int v;
  };  

  B inner_object;
};

int
main (int argc, char *argv[]) {
  A object;
    object.inner_object.v = 123;
}

Search your code for unsafe blocks or statements. These are only valid is compiled with /unsafe.

I have also faced this problem in my project. AVD is not able to reload assets,lib,res and etc folder contexts. problem : Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl.

Then,I created new projects and copied MainActivity.java,activity_main.xml, drawable context. Then delete old project from package explore,restart your Eclipse and AVD. My project is now working properly.... :) I hope this steps will help u little bit folks..!!

Russian Edition offers CSV, CSV (Macintosh) and CSV (DOS).

When saving in plain CSV, it uses windows-1251.

I just tried to save French word Résumé along with the Russian text, it saved it in HEX like 52 3F 73 75 6D 3F, 3F being the ASCII code for question mark.

When I opened the CSV file, the word, of course, became unreadable (R?sum?)

One other possible implementation, more cumbersome than the .bind() solution, but one that helps to make the point that expect() requires a function that provides a this context to the covered function, you can use a call(), e.g.,

expect(function() {model.get.call(model, 'z');}).to.throw('...');

You could store this into a temporary table.

So instead of doing the CTE/sub query you would use a temp table.

Good article on these here http://codingsight.com/introduction-to-temporary-tables-in-sql-server/

TLDR: Aggregation pipeline is faster as compared to conventional .find().sort().

Now moving to the real explanation. There are two ways to perform sorting operations in MongoDB:

1. Using .find() and .sort().
2. Or using the aggregation pipeline.

As suggested by many .find().sort() is the simplest way to perform the sorting.

.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])

However, this is a slow process compared to the aggregation pipeline.

Coming to the aggregation pipeline method. The steps to implement simple aggregation pipeline intended for sorting are:

1. $match (optional step)
2. $sort

NOTE: In my experience, the aggregation pipeline works a bit faster than the .find().sort() method.

Here's an example of the aggregation pipeline.

db.collection_name.aggregate([{
    "$match": {
        # your query - optional step
    }
},
{
    "$sort": {
        "field_1": pymongo.ASCENDING,
        "field_2": pymongo.DESCENDING,
        ....
    }
}])

Try this method yourself, compare the speed and let me know about this in the comments.

Edit: Do not forget to use allowDiskUse=True while sorting on multiple fields otherwise it will throw an error.

check this out: http://hayageek.com/docs/jquery-upload-file.php I've found it accidentally on the net.

For reference, you can also utilize initWithDictionary to init the NSMutableDictionary with a literal one:

NSMutableDictionary buttons = [[NSMutableDictionary alloc] initWithDictionary: @{
    @"touch": @0,
    @"app": @0,
    @"back": @0,
    @"volup": @0,
    @"voldown": @0
}];

you can do that

var filteredFileList = fileList.Where(fl => filterList.Contains(fl.ToString()));

Client side should use a basic validation via HTML5 input types and pattern attributes and as these are only used for progressive enhancements for better user experience (Even if they are not supported on < IE9 and safari, but we don't rely on them). But the main validation should happen on the server side..

You can use the EL 3.0 Stream API.

<div>${attachments.stream().findFirst().get()}</div>

Be careful! The EL 3.0 Stream API was finalized before the Java 8 Stream API and it is different than that. They can't sunc both apis because it will break the backward compatibility.

You are mixing mysqli and mysql function.

If your are using mysql function then instead mysqli_real_escape_string($your_variable); use

$username = mysql_real_escape_string($_POST['username']);
$pass = mysql_real_escape_string($_POST['pass']);
$pass1 = mysql_real_escape_string($_POST['pass1']);
$email = mysql_real_escape_string($_POST['email']);

If your using mysqli_* function then you have to include your connection to database into mysqli_real_escape function :

$username = mysqli_real_escape_string($your_connection, $_POST['username']);
$pass = mysqli_real_escape_string($your_connection, $_POST['pass']);
$pass1 = mysqli_real_escape_string($your_connection, $_POST['pass1']);
$email = mysqli_real_escape_string($your_connection, $_POST['email']);

Note : Use mysqli_* function since mysql has been deprecated. For information please read mysqli_*

SELECT cols.table_name, cols.column_name, cols.position, cons.status, cons.owner
FROM all_constraints cons, all_cons_columns cols
WHERE cols.table_name = 'TABLE_NAME'
AND cons.constraint_type = 'P'
AND cons.constraint_name = cols.constraint_name
AND cons.owner = cols.owner
ORDER BY cols.table_name, cols.position;

Make sure that 'TABLE_NAME' is in upper case since Oracle stores table names in upper case.

Using JDK 1.6 or later

It has been pointed out by Justin in the comments below that keytool alone is capable of doing this using the following command (although only in JDK 1.6 and later):

keytool -importkeystore -srckeystore mypfxfile.pfx -srcstoretype pkcs12 
-destkeystore clientcert.jks -deststoretype JKS

Using JDK 1.5 or below

OpenSSL can do it all. This answer on JGuru is the best method that I've found so far.

Firstly make sure that you have OpenSSL installed. Many operating systems already have it installed as I found with Mac OS X.

The following two commands convert the pfx file to a format that can be opened as a Java PKCS12 key store:

openssl pkcs12 -in mypfxfile.pfx -out mypemfile.pem
openssl pkcs12 -export -in mypemfile.pem -out mykeystore.p12 -name "MyCert"

NOTE that the name provided in the second command is the alias of your key in the new key store.

You can verify the contents of the key store using the Java keytool utility with the following command:

keytool -v -list -keystore mykeystore.p12 -storetype pkcs12

Finally if you need to you can convert this to a JKS key store by importing the key store created above into a new key store:

keytool -importkeystore -srckeystore mykeystore.p12 -destkeystore clientcert.jks -srcstoretype pkcs12 -deststoretype JKS

In addition to kieran's answer, apparently, modern browsers have an Object.keys function. In this case, you could do this:

Object.keys(jsonArray).length;

People overcomplicate this to a ridiculous extent or waste performance. Arrays? Recursion? You've got to be kidding me.

function repeat (string, times) {
  var result = ''
  while (times-- > 0) result += string
  return result
}

Edit. I ran some simple tests to compare with the bitwise version posted by artistoex / disfated and a bunch of other people. The latter was only marginally faster, but orders of magnitude more memory-efficient. For 1000000 repeats of the word 'blah', the Node process went up to 46 megabytes with the simple concatenation algorithm (above), but only 5.5 megabytes with the logarithmic algorithm. The latter is definitely the way to go. Reposting it for the sake of clarity:

function repeat (string, times) {
  var result = ''
  while (times > 0) {
    if (times & 1) result += string
    times >>= 1
    string += string
  }
  return result
}

See the docs:

Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.

Use the css display: inline-flex; value.

html

<div id='box'>
    <div class='item'></div>
    <div class='item'></div>
    <div class='item'></div>
    <div class='item'></div>
</div>

css

.box {
    display: inline-flex;
    gap: 10px; // gap between items
}

You can not do it as a member function, because the implicit this parameter is the left hand side of the <<-operator. (Hence, you would need to add it as a member function to the ostream-class. Not good :)

Could you do it as a free function without friending it? That's what I prefer, because it makes it clear that this is an integration with ostream, and not a core functionality of your class.

Tried to update the local copy, and revert the item in question, and still got the 'out of date' error. This worked for some reason:

svn update --force /path/to/dir/or/file

For Mysql please see the LOAD XML Syntax^Docs.

It should work without any additional XML transformation for the XML you've provided, just specify the format and define the table inside the database firsthand with matching column names:

LOAD XML LOCAL INFILE 'table1.xml'
    INTO TABLE table1
    ROWS IDENTIFIED BY '<table1>';

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

You can reuse your confirm:

    function doConfirm(body, $_nombrefuncion)
    {   var param = undefined;
        var $confirm = $("<div id='confirm' class='hide'></div>").dialog({
            autoOpen: false,
            buttons: {
                Yes: function() {
                param = true;
                $_nombrefuncion(param);
                $(this).dialog('close');
            },
                No: function() {
                param = false;
                $_nombrefuncion(param);
                $(this).dialog('close');
            }
                                    }
        });
        $confirm.html("<h3>"+body+"<h3>");
        $confirm.dialog('open');                                     
    };

// for this form just u must change or create a new function for to reuse the confirm
    function resultadoconfirmresetVTyBFD(param){
        $fecha = $("#asigfecha").val();
        if(param ==true){
              // DO THE CONFIRM
        }
    }

//Now just u must call the function doConfirm
    doConfirm('body message',resultadoconfirmresetVTyBFD);

You can also use showdialog

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
                      Handles Button3.Click

     dim mydialogbox as new aboutbox1
     aboutbox1.showdialog()

End Sub

Use it every time you override a method for two benefits. Do it so that you can take advantage of the compiler checking to make sure you actually are overriding a method when you think you are. This way, if you make a common mistake of misspelling a method name or not correctly matching the parameters, you will be warned that you method does not actually override as you think it does. Secondly, it makes your code easier to understand because it is more obvious when methods are overwritten.

Additionally, in Java 1.6 you can use it to mark when a method implements an interface for the same benefits. I think it would be better to have a separate annotation (like @Implements), but it's better than nothing.

If you want to continue to use passwords and not use key exchange then you can accomplish this with 'expect' like so:

#!/usr/bin/expect -f
spawn ssh user@hostname
expect "password:"
sleep 1
send "<your password>\r"
command1
command2
commandN

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

Bash 5.1 provides a straight forward way to do this with the L parameter transformation:

${var@L}

So for example you can say:

$ v="heLLo"
$ echo "${v@L}"
hello

You can also do uppercase with U:

$ v="hello"
$ echo "${v@U}"
HELLO

And uppercase the first letter with u:

$ v="hello"
$ echo "${v@u}"
Hello

Old question, but I had current problems with this issue. So I provide you my solution. Now the sources and javadocs are inside the jdk. So, unzip your jdk version.You can see that contanins a "src.zip" file. Here are your needed sources and doc files. Follow the path: Window->Preferences->Java->Installed JREs-> select your jre/jrd and press "Edit" Select all .jar files, and press Source Attachement. Select the "External File..." button, and point it to src.zip file.

Maibe a restart to Eclipse is needed. (normally not) Now you should see the docs, and also the sources for the classes from jdk.

If you have a list of lists, you only needed to use ...

import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)

per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.

I believe StringBuilder is faster if you have more than 4 strings you need to append together. Plus it can do some cool things like AppendLine.

I've tweaked LostCajun's excellent post above to exclude system stored procedures. I also removed "Extract." from the code because I couldn't figure out what it's for and it gave me errors. The "fetch next" statement inside the loop also needed an "into" clause.

use <<databasename>>
go

declare @aQuery nvarchar(1024);
declare @spName nvarchar(64);
declare allSP cursor for
    select p.name  
    from sys.procedures p 
    where p.type_desc = 'SQL_STORED_PROCEDURE' 
    and LEFT(p.name,3) NOT IN ('sp_','xp_','ms_')
    order by p.name;
open allSP;
fetch next from allSP into @spName;
while (@@FETCH_STATUS = 0)
begin
    set @aQuery = 'sp_helptext [' + @spName + ']';
    exec sp_executesql @aQuery;
    fetch next from allSP into @spName;
end;
close allSP;
deallocate allSP;

I would like to add that you should make sure that the generated config.yml file when doing ruby dk.rb init contains the path to the ruby installation you want to use DevKit with. In my case, I had the Heroku Toolbelt installed on my system, which provided its own ruby installation, located at a different place. The config.yml file used that particular installation, and that's not what I wanted. I had to manually edit the file to point it to the correct one, then continue with ruby dk.rb review, etc.

This is with reference to @Ladislav Mrnka's answer on using fluent api for configuring one-to-one relationship.

Had a situation where having FK of dependent must be it's PK was not feasible.

E.g., Foo already has one-to-many relationship with Bar.

public class Foo {
   public Guid FooId;
   public virtual ICollection<> Bars; 
}
public class Bar {
   //PK
   public Guid BarId;
   //FK to Foo
   public Guid FooId;
   public virtual Foo Foo;
}

Now, we had to add another one-to-one relationship between Foo and Bar.

public class Foo {
   public Guid FooId;
   public Guid PrimaryBarId;// needs to be removed(from entity),as we specify it in fluent api
   public virtual Bar PrimaryBar;
   public virtual ICollection<> Bars;
}
public class Bar {
   public Guid BarId;
   public Guid FooId;
   public virtual Foo PrimaryBarOfFoo;
   public virtual Foo Foo;
}

Here is how to specify one-to-one relationship using fluent api:

modelBuilder.Entity<Bar>()
            .HasOptional(p => p.PrimaryBarOfFoo)
            .WithOptionalPrincipal(o => o.PrimaryBar)
            .Map(x => x.MapKey("PrimaryBarId"));

Note that while adding PrimaryBarId needs to be removed, as we specifying it through fluent api.

Also note that method name [WithOptionalPrincipal()][1] is kind of ironic. In this case, Principal is Bar. WithOptionalDependent() description on msdn makes it more clear.

If the data set contains many rows it might be more efficient to join with a lookup table using data.table instead of nested ifelse().

Provided the lookup table below

lookup

     idnat     idbp   idnat2
1:  french mainland mainland
2:  french   colony overseas
3:  french overseas overseas
4: foreign  foreign  foreign

and a sample data set

library(data.table)
n_row <- 10L
set.seed(1L)
DT <- data.table(idnat = "french",
                 idbp = sample(c("mainland", "colony", "overseas", "foreign"), n_row, replace = TRUE))
DT[idbp == "foreign", idnat := "foreign"][]

      idnat     idbp
 1:  french   colony
 2:  french   colony
 3:  french overseas
 4: foreign  foreign
 5:  french mainland
 6: foreign  foreign
 7: foreign  foreign
 8:  french overseas
 9:  french overseas
10:  french mainland

then we can do an update while joining:

DT[lookup, on = .(idnat, idbp), idnat2 := i.idnat2][]

      idnat     idbp   idnat2
 1:  french   colony overseas
 2:  french   colony overseas
 3:  french overseas overseas
 4: foreign  foreign  foreign
 5:  french mainland mainland
 6: foreign  foreign  foreign
 7: foreign  foreign  foreign
 8:  french overseas overseas
 9:  french overseas overseas
10:  french mainland mainland

3. add this line

   extension=pdo_mysql.so
   

4. then run

The "break" command does not work within an "if" statement.

If you remove the "break" command from your code and then test the code, you should find that the code works exactly the same without a "break" command as with one.

"Break" is designed for use inside loops (for, while, do-while, enhanced for and switch).

The full list of readyState values is:

State  Description
0      The request is not initialized
1      The request has been set up
2      The request has been sent
3      The request is in process
4      The request is complete

(from https://www.w3schools.com/js/js_ajax_http_response.asp)

In practice you almost never use any of them except for 4.

Some XMLHttpRequest implementations may let you see partially received responses in responseText when readyState==3, but this isn't universally supported and shouldn't be relied upon.

Here is my solution I've used in applications.

I disabled the body overflow and placed the entire website html inside container div's. The website containers have overflow and therefore the user may scroll the page as expected.

I then created a sibling div (#Prevent) with a higher z-index that covers the entire website. Since #Prevent has a higher z-index, it overlaps the website container. When #Prevent is visible the mouse is no longer hovering the website containers, so scrolling isn't possible.

You may of course place another div, such as your modal, with a higher z-index than #Prevent in the markup. This allows you to create pop-up windows that don't suffer from scrolling issues.

This solution is better because it doesn't hide the scrollbars (jumping affect). It doesn't require event listeners and it's easy to implement. It works in all browsers, although with IE7 & 8 you have to play around (depends on your specific code).

html

<body>
  <div id="YourModal" style="display:none;"></div>
  <div id="Prevent" style="display:none;"></div>
  <div id="WebsiteContainer">
     <div id="Website">
     website goes here...
     </div>
  </div>
</body>

css

body { overflow: hidden; }

#YourModal {
 z-index:200;
 /* modal styles here */
}

#Prevent {
 z-index:100;
 position:absolute;
 left:0px;
 height:100%;
 width:100%;
 background:transparent;
}

#WebsiteContainer {
  z-index:50;
  overflow:auto;
  position: absolute;
  height:100%;
  width:100%;
}
#Website {
  position:relative;
}

jquery/js

function PreventScroll(A) { 
  switch (A) {
    case 'on': $('#Prevent').show(); break;
    case 'off': $('#Prevent').hide(); break;
  }
}

disable/enable the scroll

PreventScroll('on'); // prevent scrolling
PreventScroll('off'); // allow scrolling

You can use Named Sections.

_Layout.cshtml

<head>
    <script type="text/javascript" src="@Url.Content("/Scripts/jquery-1.6.2.min.js")"></script>
    @RenderSection("JavaScript", required: false)

If you want to first take mean on the combination of ['cluster', 'org'] and then take mean on cluster groups, you can use:

In [59]: (df.groupby(['cluster', 'org'], as_index=False).mean()
            .groupby('cluster')['time'].mean())
Out[59]:
cluster
1          15
2          54
3           6
Name: time, dtype: int64

If you want the mean of cluster groups only, then you can use:

In [58]: df.groupby(['cluster']).mean()
Out[58]:
              time
cluster
1        12.333333
2        54.000000
3         6.000000

You can also use groupby on ['cluster', 'org'] and then use mean():

In [57]: df.groupby(['cluster', 'org']).mean()
Out[57]:
               time
cluster org
1       a    438886
        c        23
2       d      9874
        h        34
3       w         6

You may not place the deprecated non-block-scoped stage (as in the original question) inside parallel.

As of JENKINS-26107, stage takes a block argument. You may put parallel inside stage or stage inside parallel or stage inside stage etc. However visualizations of the build are not guaranteed to support all nestings; in particular

• The built-in Pipeline Steps (a “tree table” listing every step run by the build) shows arbitrary stage nesting.
• The Pipeline Stage View plugin will currently only display a linear list of stages, in the order they started, regardless of nesting structure.
• Blue Ocean will display top-level stages, plus parallel branches inside a top-level stage, but currently no more.

JENKINS-27394, if implemented, would display arbitrarily nested stages.

I was recently working with IPFS and worked this out. A curl example for IPFS to upload a file looks like this:

curl -i -H "Content-Type: multipart/form-data; boundary=CUSTOM" -d $'--CUSTOM\r\nContent-Type: multipart/octet-stream\r\nContent-Disposition: file; filename="test"\r\n\r\nHello World!\n--CUSTOM--' "http://localhost:5001/api/v0/add"

The basic idea is that each part (split by string in boundary with --) has it's own headers (Content-Type in the second part, for example.) The FormData object manages all this for you, so it's a better way to accomplish our goals.

This translates to fetch API like this:

const formData = new FormData()
formData.append('blob', new Blob(['Hello World!\n']), 'test')

fetch('http://localhost:5001/api/v0/add', {
  method: 'POST',
  body: formData
})
.then(r => r.json())
.then(data => {
  console.log(data)
})

For those of us using non-ISO standard date formats, like civilian vernacular 01/01/2001 (mm/dd/YYYY), including time in a 12hour date format with am/pm marks, the following function will return a valid Date object:

function convertDate(date) {

    // # valid js Date and time object format (YYYY-MM-DDTHH:MM:SS)
    var dateTimeParts = date.split(' ');

    // # this assumes time format has NO SPACE between time and am/pm marks.
    if (dateTimeParts[1].indexOf(' ') == -1 && dateTimeParts[2] === undefined) {

        var theTime = dateTimeParts[1];

        // # strip out all except numbers and colon
        var ampm = theTime.replace(/[0-9:]/g, '');

        // # strip out all except letters (for AM/PM)
        var time = theTime.replace(/[[^a-zA-Z]/g, '');

        if (ampm == 'pm') {

            time = time.split(':');

            // # if time is 12:00, don't add 12
            if (time[0] == 12) {
                time = parseInt(time[0]) + ':' + time[1] + ':00';
            } else {
                time = parseInt(time[0]) + 12 + ':' + time[1] + ':00';
            }

        } else { // if AM

            time = time.split(':');

            // # if AM is less than 10 o'clock, add leading zero
            if (time[0] < 10) {
                time = '0' + time[0] + ':' + time[1] + ':00';
            } else {
                time = time[0] + ':' + time[1] + ':00';
            }
        }
    }
    // # create a new date object from only the date part
    var dateObj = new Date(dateTimeParts[0]);

    // # add leading zero to date of the month if less than 10
    var dayOfMonth = (dateObj.getDate() < 10 ? ("0" + dateObj.getDate()) : dateObj.getDate());

    // # parse each date object part and put all parts together
    var yearMoDay = dateObj.getFullYear() + '-' + (dateObj.getMonth() + 1) + '-' + dayOfMonth;

    // # finally combine re-formatted date and re-formatted time!
    var date = new Date(yearMoDay + 'T' + time);

    return date;
}

Usage:

date = convertDate('11/15/2016 2:00pm');

Try this something like this:

var p_ids = document.forms[0].elements["p_id[]"];
alert(p_ids.length);
for (var i = 0, len = p_ids.length; i < len; i++) {
  alert(p_ids[i].value);
}

Guard statement going to do . it is couple of different

1) it is allow me to reduce nested if statement
2) it is increase my scope which my variable accessible

if Statement

func doTatal(num1 : Int?, num2: Int?) {
  // nested if statement
    if let fistNum = num1 where num1 > 0 {
        if let lastNum = num2 where num2 < 50 {

          let total = fistNum + lastNum
        }
    }
 // don't allow me to access out of the scope 
 //total = fistNum + lastNum 
}

Guard statement

func doTatal(num1 : Int?, num2: Int?) {
   //reduce  nested if statement and check positive way not negative way 
    guard let fistNum = num1 where num1 > 0 else{
      return
    }
    guard  let lastNum = num2 where num2 < 50 else {
     return
    }
    // increase my scope which my variable accessible
    let total = fistNum + lastNum

}

Because all attempts to print the argument I placed in my variable failed, here my 2 bytes for this question:

std::string dump_name;

(stuff..)

if(argc>2)
{
    dump_name.assign(argv[2]);
    fprintf(stdout, "ARGUMENT %s", dump_name.c_str());
}

Note the use of assign, and also the need for the c_str() function call.

Seems bit strange code. To get string from Utf8 byte stream all you need to do is:

string str = Encoding.UTF8.GetString(utf8ByteArray);

If you need to save iso-8859-1 byte stream to somewhere then just use: additional line of code for previous:

byte[] iso88591data = Encoding.GetEncoding("ISO-8859-1").GetBytes(str);

When i use a machine which has never visited my online banking web site i get asked for additional authentification. then, if i go back a second time to the online banking site i dont get asked the additional authentification...i deleted all cookies in IE and relogged onto my online banking site fully expecting to be asked the authentification questions again. to my surprise i was not asked. doesnt this lead one to believe the bank is doing some kind of pc tagging which doesnt involve cookies?

This is a pretty common type of authentication used by banks.

Say you're accessing your bank website via example-isp.com. The first time you're there, you'll be asked for your password, as well as additional authentication. Once you've passed, the bank knows that user "thatisvaliant" is authenticated to access the site via example-isp.com.

In the future, it won't ask for extra authentication (beyond your password) when you're accessing the site via example-isp.com. If you try to access the bank via another-isp.com, the bank will go through the same routine again.

So to summarize, what the bank's identifying is your ISP and/or netblock, based on your IP address. Obviously not every user at your ISP is you, which is why the bank still asks you for your password.

Have you ever had a credit card company call to verify that things are OK when you use a credit card in a different country? Same concept.

THIS works

<div style="display:inline-block;margin:10px auto;">
    <ul style="list-style-type:none;">

This is common issue, another way is to use DataTable object

DataTable dt = new DataTable();
dt.Columns.Add("column name");

dt.Rows.Add(new object[] { "Item 1" });
dt.Rows.Add(new object[] { "Item 2" });
dt.Rows.Add(new object[] { "Item 3" });

This problem is described in detail here: http://www.psworld.pl/Programming/BindingListOfString

select sequence_owner, sequence_name from dba_sequences;


DBA_SEQUENCES -- all sequences that exist 
ALL_SEQUENCES  -- all sequences that you have permission to see 
USER_SEQUENCES  -- all sequences that you own

Note that since you are, by definition, the owner of all the sequences returned from USER_SEQUENCES, there is no SEQUENCE_OWNER column in USER_SEQUENCES.

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

This is the command to use to tell Gradle to upgrade the wrapper such that it will grab the distribution versions of libraries that includes source code:

./gradlew wrapper --gradle-version <version> --distribution-type all

Specifying the distribution-type with "all" will make sure Gradle downloads source files for use by your development environment.

Pros:

• IDEs will have immediate access to source code. For example, Intellij IDEA won't prompt you to update your build scripts to include the source distro (because this command already did that)

Cons:

• Longer/Bigger build process because it's downloading source code. This is a waste of time/space on a build or CI server where the source code is not necessary.

Please comment or provide another answer if you know of any command line option to tell Gradle not to download sources on a build server.

You can use it as follows,

<td>

<input type="submit" name="save" class="noborder" id="save" value="Save" alt="Save" 
tabindex="4" />

</td>

<td>

<input type="submit" name="publish" class="noborder" id="publish" value="Publish" 
alt="Publish" tabindex="5" />

</td>

And in PHP,

<?php
if($_POST['save'])
{
   //Save Code
}
else if($_POST['publish'])
{
   //Publish Code
}
?>

from itertools import product 
list_vals = [['Brand Acronym:CBIQ', 'Brand Acronym :KMEFIC'],['Brand Country:DXB','Brand Country:BH']]

('Brand Acronym:CBIQ', 'Brand Country:BH'),
('Brand Acronym :KMEFIC', 'Brand Country :DXB'),
('Brand Acronym :KMEFIC', 'Brand Country:BH')]

@David Conrad solution is the fastest I tried using the Normalizer, but it does have a bug. It basically strips characters which are not accents, for example Chinese characters and other letters like æ, are all stripped. The characters that we want to strip are non spacing marks, characters which don't take up extra width in the final string. These zero width characters basically end up combined in some other character. If you can see them isolated as a character, for example like this `, my guess is that it's combined with the space character.

public static String flattenToAscii(String string) {
    char[] out = new char[string.length()];
    String norm = Normalizer.normalize(string, Normalizer.Form.NFD);

    int j = 0;
    for (int i = 0, n = norm.length(); i < n; ++i) {
        char c = norm.charAt(i);
        int type = Character.getType(c);

        //Log.d(TAG,""+c);
        //by Ricardo, modified the character check for accents, ref: http://stackoverflow.com/a/5697575/689223
        if (type != Character.NON_SPACING_MARK){
            out[j] = c;
            j++;
        }
    }
    //Log.d(TAG,"normalized string:"+norm+"/"+new String(out));
    return new String(out);
}

I'll Explain how to add an image using Android studio(2.3.3). First you need to add the image into res/drawable folder in the project. Like below

Now in go to activity_main.xml (or any activity you need to add image) and select the Design view. There you can see your Palette tool box on left side. You need to drag and drop ImageView.

It will prompt you Resources dialog box. In there select Drawable under the project section you can see your image. Like below

Select the image you want press Ok you can see the image on the Design view. If you want it configure using xml it would look like below.

<ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/homepage"
        tools:layout_editor_absoluteX="55dp"
        tools:layout_editor_absoluteY="130dp" />

You need to give image location using

app:srcCompat="@drawable/imagename"

Yes, each package must be defined in its own directory.

The source structure is defined in How to Write Go Code.

A package is a component that you can use in more than one program, that you can publish, import, get from an URL, etc. So it makes sense for it to have its own directory as much as a program can have a directory.

You can set the textarea's height to its scrollHeight on all events that change its potential size:

function setTextareaResponsive(id) {
   adjustTextAreaHeight(id);

   $(window).on("resize", function() {
      adjustTextareaHeight(id);
   });

   $("#" + id).on("change input", function() {
      adjustTextareaHeight(id);
   });
}

function adjustTextareaHeight(id) {
   // set height to 1, so scrollHeight is related to linecount, not original textarea size
   $("#" + id).height(1);
   $("#" + id).height(document.getElementById(id).scrollHeight);
}

I personally like it better, when the height is not padded by the extra height (usually 12px) that scrollHeight provides. That's why I like to set the height to the number of lines multiplied by the lineHeight, in which case the function adjustTextareaHeight would look like this:

function adjustTextareaHeight(id) {
   var textarea = document.getElementById(id);

   // set height to 1, so scrollHeight is related to linecount, not original textarea size
   $("#" + id).height(1);
   var lineHeight = parseInt(getComputedStyle(textarea).lineHeight)
   var numberOfLines = Math.floor(textarea.scrollHeight / lineHeight)
   $("#" + id).height(lineHeight * numberOfLines);
}

You may use parseInt :

int id = Integer.parseInt(jsonObj.get("id"));

or better and more directly the getInt method :

int id = jsonObj.getInt("id");

Check the link Regular Expression Demo

use the below reg exp

[a-z] + [^0-9\s.]+|.(?!\d)

Example :

public static String getStringSizeLengthFile(long size) {

    DecimalFormat df = new DecimalFormat("0.00");

    float sizeKb = 1024.0f;
    float sizeMb = sizeKb * sizeKb;
    float sizeGb = sizeMb * sizeKb;
    float sizeTerra = sizeGb * sizeKb;


    if(size < sizeMb)
        return df.format(size / sizeKb)+ " Kb";
    else if(size < sizeGb)
        return df.format(size / sizeMb) + " Mb";
    else if(size < sizeTerra)
        return df.format(size / sizeGb) + " Gb";

    return "";
}

A short demonstration of @gregmac's (excellent and detailed) answer, which essentially recommends $PSCommandPath as the only reliable command to return the currently running script where Powershell 3.0 and above is used.

Here I show returning either the full path or just the file name.

Test.ps1:

'Direct:'
$PSCommandPath  # Full Path 
Split-Path -Path $PSCommandPath -Leaf  # File Name only

function main () {
  ''
  'Within a function:'
  $PSCommandPath
  Split-Path -Path $PSCommandPath -Leaf
}

main

Output:

PS> .\Test.ps1
Direct:
C:\Users\John\Documents\Sda\Code\Windows\PowerShell\Apps\xBankStatementRename\Test.ps1
Test.ps1

Within a function:
C:\Users\John\Documents\Sda\Code\Windows\PowerShell\Apps\xBankStatementRename\Test.ps1
Test.ps1

Edit the source (or turn off rich text) and replace the p tag with a div. Then style the div any which way you want.

ckEditor won't add any wrapper element on the next submit as you've got the div in there.

(This solved my issue, I'm using Drupal and need small snippets of html which the editor always added the extra, but the rest of the time I want the wrapping p tag).

"Am i doing it right?Is there better/smarter way to achieve the output this code gave me?"

Generally speaking, yes, you're doing it right. Tkinter has no native scrollable container other than the canvas. As you can see, it's really not that difficult to set up. As your example shows, it only takes 5 or 6 lines of code to make it work -- depending on how you count lines.

"Why must i use grid method?(i tried place method, but none of the labels appear on the canvas?)"

You ask about why you must use grid. There is no requirement to use grid. Place, grid and pack can all be used. It's simply that some are more naturally suited to particular types of problems. In this case it looks like you're creating an actual grid -- rows and columns of labels -- so grid is the natural choice.

"What so special about using anchor='nw' when creating window on canvas?"

The anchor tells you what part of the window is positioned at the coordinates you give. By default, the center of the window will be placed at the coordinate. In the case of your code above, you want the upper left ("northwest") corner to be at the coordinate.

From your description, it looks like that you want to "reserve" the allocated storage space of vector t_Names.

Take note that resize initialize the newly allocated vector where reserve just allocates but does not construct. Hence, 'reserve' is much faster than 'resize'

You can refer to the documentation regarding the difference of resize and reserve

Use a simple background image for the textarea suffice.

Or

<div onselectstart="return false">your text</div>

This image presents both orientation(Landscape/Portrait)

To get MaxX and MaxY, read on.

For Android device screen coordinates, below concept will work.

Display mdisp = getWindowManager().getDefaultDisplay();
Point mdispSize = new Point();
mdisp.getSize(mdispSize);
int maxX = mdispSize.x; 
int maxY = mdispSize.y;

EDIT:- ** **for devices supporting android api level older than 13. Can use below code.

    Display mdisp = getWindowManager().getDefaultDisplay();
    int maxX= mdisp.getWidth();
    int maxY= mdisp.getHeight();

(x,y) :-

1) (0,0) is top left corner.

2) (maxX,0) is top right corner

3) (0,maxY) is bottom left corner

4) (maxX,maxY) is bottom right corner

here maxX and maxY are screen maximum height and width in pixels, which we have retrieved in above given code.

I think I found the proper way to do it...

// Create a DOM Text node:
var text_node = document.createTextNode(unescaped_text);

// Get the HTML element where you want to insert the text into:
var elem = document.getElementById('msg_span');

// Optional: clear its old contents
//elem.innerHTML = '';

// Append the text node into it:
elem.appendChild(text_node);

Quoting Conventions for Web Developers

The Short Answer

In HTML the use of single quotes (') and double quotes (") are interchangeable, there is no difference.

But consistency is recommended, therefore we must pick a syntax convention and use it regularly.

The Long Answer

Web Development often consists of many programming languages. HTML, JS, CSS, PHP, ASP, RoR, Python, ect. Because of this we have many syntax conventions for different programing languages. Often habbits from one language will follow us to other languages, even if it is not considered "proper" i.e. commenting conventions. Quoting conventions also falls into this category for me.

But I tend to use HTML tightly in conjunction with PHP. And in PHP there is a major difference between single quotes and double quotes. In PHP with double quotes "you can insert variables directly within the text of the string". (scriptingok.com) And when using single quotes "the text appears as it is". (scriptingok.com)

PHP takes longer to process double quoted strings. Since the PHP parser has to read the whole string in advance to detect any variable inside—and concatenate it—it takes longer to process than a single quoted string. (scriptingok.com)

Single quotes are easier on the server. Since PHP does not need to read the whole string in advance, the server can work faster and happier. (scriptingok.com)

Other things to consider

1. Frequency of double quotes within string. I find that I need to use double quotes (") within my strings more often than I need to use single quotes (') within strings. To reduce the number of character escapes needed I favor single quote delimiters.
2. It's easier to make a single quote. This is fairly self explanatory but to clarify, why press the SHIFT key more times then you have to.

My Convention

With this understanding of PHP I have set the convention (for myself and the rest of my company) that strings are to be represented as single quotes by default for server optimization. Double quotes are used within the string if a quotes are required such as JavaScript within an attribute, for example:

<button onClick='func("param");'>Press Me</button>

Of course if we are in PHP and want the parser to handle PHP variables within the string we should intentionally use double quotes. $a='Awesome'; $b = "Not $a";

The best solution in this case is to normalize your table to have the comma separated values in different rows (First normal form 1NF) http://en.wikipedia.org/wiki/First_normal_form

For that, you can implement a nice Split table valued function in SQL, by using CLR http://bi-tch.blogspot.com/2007/10/sql-clr-net-function-split.html or using plain SQL.

CREATE FUNCTION dbo.Split
(
    @RowData nvarchar(2000),
    @SplitOn nvarchar(5)
)  
RETURNS @RtnValue table 
(
    Id int identity(1,1),
    Data nvarchar(100)
) 
AS  
BEGIN 
    Declare @Cnt int
    Set @Cnt = 1

    While (Charindex(@SplitOn,@RowData)>0)
    Begin
        Insert Into @RtnValue (data)
        Select 
            Data = ltrim(rtrim(Substring(@RowData,1,Charindex(@SplitOn,@RowData)-1)))

        Set @RowData = Substring(@RowData,Charindex(@SplitOn,@RowData)+1,len(@RowData))
        Set @Cnt = @Cnt + 1
    End

    Insert Into @RtnValue (data)
    Select Data = ltrim(rtrim(@RowData))

    Return
END

Then you can query the normalized output by using cross apply

select distinct a.id_column
from   MyTable a cross apply
       dbo.Split(A.MyCol,',') b
where  b.Data='Cat'

Please don't use MD5 for password hashing. Such passwords can be cracked in milliseconds. You're sure to be pwned by cybercriminals.

PHP offers a high-quality and future proof password hashing subsystem based on a reliable random salt and multiple rounds of Rijndael / AES encryption.

When a user first provides a password you can hash it like this:

 $pass = 'whatever the user typed in';
 $hashed_password = password_hash( "secret pass phrase", PASSWORD_DEFAULT );

Then, store $hashed_password in a varchar(255) column in MySQL. Later, when the user wants to log in, you can retrieve the hashed password from MySQL and compare it to the password the user offered to log in.

 $pass = 'whatever the user typed in';
 $hashed_password = 'what you retrieved from MySQL for this user';
 if ( password_verify ( $pass , $hashed_password )) {
    /* future proof the password */
    if ( password_needs_rehash($hashed_password , PASSWORD_DEFAULT)) {
       /* recreate the hash */
       $rehashed_password = password_hash($pass, PASSWORD_DEFAULT );
       /* store the rehashed password in MySQL */
     }
     /* password verified, let the user in */
 }
 else {
     /* password not verified, tell the intruder to get lost */
 }

How does this future-proofing work? Future releases of PHP will adapt to match faster and easier to crack encryption. If it's necessary to rehash passwords to make them harder to crack, the future implementation of the password_needs_rehash() function will detect that.

Don't reinvent the flat tire. Use professionally designed and vetted open source code for security.

Go to File->Settings->Version Control->Subversion enter the path for your SVN executable in the General tab under Subversion configuration directory. Also, you can download a latest SVN client such as VisualSVN and point the path to the executable as mentioned above. That will most likely solve your problem.

try this

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

You can consider to replace default WordPress jQuery script with Google Library by adding something like the following into theme functions.php file:

function modify_jquery() {
    if (!is_admin()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js', false, '1.10.2');
        wp_enqueue_script('jquery');
    }
}
add_action('init', 'modify_jquery');

Based on Piotr Migdals response I want to give an alternate solution enabling the possibility for a vector of strings:

myVectorOfStrings <- c("foo", "bar")
matchExpression <- paste(myVectorOfStrings, collapse = "|")
# [1] "foo|bar"
df %>% select(matches(matchExpression))

Making use of the regex OR operator (|)

ATTENTION: If you really have a plain vector of column names (and do not need the power of RegExpression), please see the comment below this answer (since it's the cleaner solution).

You can grow them row by row by appending or using rbind().

That does not mean you should. Dynamically growing structures is one of the least efficient ways to code in R.

If you can, allocate your entire data.frame up front:

N <- 1e4  # total number of rows to preallocate--possibly an overestimate

DF <- data.frame(num=rep(NA, N), txt=rep("", N),  # as many cols as you need
                 stringsAsFactors=FALSE)          # you don't know levels yet

and then during your operations insert row at a time

DF[i, ] <- list(1.4, "foo")

That should work for arbitrary data.frame and be much more efficient. If you overshot N you can always shrink empty rows out at the end.

Normal ways would be Integer.toString(i) or String.valueOf(i).

int i = 5;
String strI = String.valueOf(i);

Or

int aInt = 1;    
String aString = Integer.toString(aInt);

called_from must be null. Add a test against that condition like

if (called_from != null && called_from.equalsIgnoreCase("add")) {

or you could use Yoda conditions (per the Advantages in the linked Wikipedia article it can also solve some types of unsafe null behavior they can be described as placing the constant portion of the expression on the left side of the conditional statement)

if ("add".equalsIgnoreCase(called_from)) { // <-- safe if called_from is null

Use ViewChild with #localvariable as shown here,

<textarea  #someVar  id="tasknote"
                  name="tasknote"
                  [(ngModel)]="taskNote"
                  placeholder="{{ notePlaceholder }}"
                  style="background-color: pink"
                  (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }}

In component,

OLDEST Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

ngAfterViewInit()
{
   this.el.nativeElement.focus();
}

OLD Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer) {}
ngAfterViewInit() {
    this.rd.invokeElementMethod(this.el.nativeElement,'focus');
}

NEW Way

Please note from Angular v4.0.0-rc.3 (2017-03-10) few things have been changed. Since Angular team will deprecate invokeElementMethod, above code no longer can be used.

BREAKING CHANGES

since 4.0 rc.1:

rename RendererV2 to Renderer2
rename RendererTypeV2 to RendererType2
rename RendererFactoryV2 to RendererFactory2

import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer2) {}

ngAfterViewInit() {
      console.log(this.rd); 
      this.el.nativeElement.focus();      //<<<=====same as oldest way
}

console.log(this.rd) will give you following methods and you can see now invokeElementMethod is not there. Attaching img as yet it is not documented.

NOTE: You can use following methods of Rendere2 with/without ViewChild variable to do so many things.

To save you some time here is the answer from a link in a previous answer at https://forums.asp.net/t/1448398.aspx

ActionResult is an abstract class, and it's base class for ViewResult class.

In MVC framework, it uses ActionResult class to reference the object your action method returns. And invokes ExecuteResult method on it.

And ViewResult is an implementation for this abstract class. It will try to find a view page (usually aspx page) in some predefined paths(/views/controllername/, /views/shared/, etc) by the given view name.

It's usually a good practice to have your method return a more specific class. So if you are sure that your action method will return some view page, you can use ViewResult. But if your action method may have different behavior, like either render a view or perform a redirection. You can use the more general base class ActionResult as the return type.

If you want to open it for a range and for a protocol

ufw allow 11200:11299/tcp
ufw allow 11200:11299/udp

as this example you can change ip and port this works with me

php artisan serve --host=0.0.0.0 --port=8000

Try this instead:

  =SUM(IF(MONTH($A$2:$A$6)=1,$B$2:$B$6,0))

It's an array formula, so you will need to enter it with the Control-Shift-Enter key combination.

Here's how the formula works.

1. MONTH($A$2:$A$6) creates an array of numeric values of the month for the dates in A2:A6, that is,
   {1, 1, 1, 2, 2}.
2. Then the comparison {1, 1, 1, 2, 2}= 1 produces the array {TRUE, TRUE, TRUE, FALSE, FALSE}, which comprises the condition for the IF statement.
3. The IF statement then returns an array of values, with {430, 96, 400.. for the values of the sum ranges where the month value equals 1 and ..0,0} where the month value does not equal 1.
4. That array {430, 96, 400, 0, 0} is then summed to get the answer you are looking for.

This is essentially equivalent to what the SUMIF and SUMIFs functions do. However, neither of those functions support the kind of calculation you tried to include in the conditional.

It's also possible to drop the IF completely. Since TRUE and FALSE can also be treated as 1 and 0, this formula--=SUM((MONTH($A$2:$A$6)=1)*$B$2:$B$6)--also works.

Heads up: This does not work in Google Spreadsheets

If you do not want to install anything at all you can "build your own" batch file that does the job from standard Windows commands. Here are some pointers as to how to do it.

1) Using find /c /v "" yourinput.file, get the number of lines in your input file. The output is something like:

---------- T.TXT: 15

2) Using for /f, parse this output to get the number 15.

3) Using set /a, calculate the number of head lines that needs to be skipped

4) Using for /f "skip=n" skip the head lines and echo/process the tail lines.

If I find the time, I will build such a batch file and post it back here.

EDIT: tail.bat

REM tail.bat
REM
REM Usage: tail.bat <file> <number-of-lines>

REM Examples: tail.bat myfile.txt 10

The reason of this warning is i was presenting a view controller over a small view that is not full size view. Given below is the image of my project. where on click on four option above. User navigate to different childviewcontroller's view.(it works like tabViewcontroller). But the childviewcontroller contains view of small size. So if we present a view from childviewcontroller it gives this warning.

And to avoid this, you can present a view on childviewcontroller's parent

  [self.parentViewController presentViewController:viewController animated:YES completion:nil];

Although Clayton's answer will get you there (eventually), in SQL2005/2008/R2/2012 you have a far easier option:

Right-click on the Database, select Tasks and then Generate Scripts, which will launch the Script Wizard. This allows you to generate a single script that can recreate the full database including table/indexes & constraints/stored procedures/functions/users/etc. There are a multitude of options that you can configure to customise the output, but most of it is self explanatory.

If you are happy with the default options, you can do the whole job in a matter of seconds.

If you want to recreate the data in the database (as a series of INSERTS) I'd also recommend SSMS Tools Pack (Free for SQL 2008 version, Paid for SQL 2012 version).

You can export the date using this command.

<?php

$list = array (
    array('aaa', 'bbb', 'ccc', 'dddd'),
    array('123', '456', '789'),
    array('"aaa"', '"bbb"')
);

$fp = fopen('file.csv', 'w');

foreach ($list as $fields) {
    fputcsv($fp, $fields);
}

fclose($fp);
?>

First you must load the data from the mysql server in to a array

I have been using both committing the node_modules folder and shrink-wrapping. Both solutions did not make me happy.

In short: a committed node_modules folder adds too much noise to the repository.And shrinkwrap.json is not easy to manage and there isn't any guarantee that some shrink-wrapped project will build in a few years.

I found that Mozilla was using a separate repository for one of their projects: https://github.com/mozilla-b2g/gaia-node-modules

So it did not take me long to implement this idea in a Node.js CLI tool: https://github.com/bestander/npm-git-lock

Just before every build, add:

npm-git-lock --repo [[email protected]:your/dedicated/node_modules/git/repository.git]

It will calculate the hash of your package.json file and will either check out folder node_modules content from a remote repository, or, if it is a first build for this package.json file, will do a clean npm install and push the results to the remote repository.

I have had a similar scenario in Laravel and solved it in the following way.

The password contains characters from at least three of the following five categories:

• English uppercase characters (A – Z)
• English lowercase characters (a – z)
• Base 10 digits (0 – 9)
• Non-alphanumeric (For example: !, $, #, or %)
• Unicode characters

First, we need to create a regular expression and validate it.

Your regular expression would look like this:

^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$

I have tested and validated it on this site. Yet, perform your own in your own manner and adjust accordingly. This is only an example of regex, you can manipluated the way you want.

So your final Laravel code should be like this:

'password' => 'required|
               min:6|
               regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$/|
               confirmed',

Update As @NikK in the comment mentions, in Laravel 5.5 and newer the the password value should encapsulated in array Square brackets like

'password' => ['required', 
               'min:6', 
               'regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$/', 
               'confirmed']

I have not testing it on Laravel 5.5 so I am trusting @NikK hence I have moved to working with c#/.net these days and have no much time for Laravel.

Note:

1. I have tested and validated it on both the regular expression site and a Laravel 5 test environment and it works.
2. I have used min:6, this is optional but it is always a good practice to have a security policy that reflects different aspects, one of which is minimum password length.
3. I suggest you to use password confirmed to ensure user typing correct password.
4. Within the 6 characters our regex should contain at least 3 of a-z or A-Z and number and special character.
5. Always test your code in a test environment before moving to production.
6. Update: What I have done in this answer is just example of regex password

I think what you mean is how to encapsulate that for general use, e.g. in a function:

def sum_list(l):
    sum = 0
    for x in l:
        sum += x
    return sum

Now you can apply this to any list. Examples:

l = [1, 2, 3, 4, 5]
sum_list(l)

l = list(map(int, input("Enter numbers separated by spaces: ").split()))
sum_list(l)

But note that sum is already built in!

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

for (int i = 0; i < list.size(); i++) {
  for (int j = i+1; j < list.size(); j++) {
    // compare list.get(i) and list.get(j)
  }
}

You need to put the format arguments into a tuple (add parentheses):

instr = "'%s', '%s', '%d', '%s', '%s', '%s', '%s'" % (softname, procversion, int(percent), exe, description, company, procurl)

What you currently have is equivalent to the following:

intstr = ("'%s', '%s', '%d', '%s', '%s', '%s', '%s'" % softname), procversion, int(percent), exe, description, company, procurl

Example:

>>> "%s %s" % 'hello', 'world'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not enough arguments for format string
>>> "%s %s" % ('hello', 'world')
'hello world'

Are you missing a function declaration?

void ac_search(uint num_patterns, uint pattern_length, const char *patterns, 
               uint num_records, uint record_length, const char *records, int *matches, Node* trie);

Add it just before your implementation of ac_benchmark_search.

Is it possible that MySql listening on the same port as JBoss?

Is there a port number given in the error message - something like Address already in use: JVM_Bind:8080

You can change the port in JBoss server.xml to test this.

Clearing the value of 0th index of input worked for me. Please try the below code, hope this will work (AngularJs).

          scope.onClick = function() {
            input[0].value = "";
                input.click();
            };

use command with sudo,

sudo apt-get autoremove --purge mongodb

OR

sudo apt-get remove mongodb* --purge

It will remove complete mongodb

After installation of Visual Studio Community 2015 Edition on Windows 10 64 bit. This error did not go. Then I install Microsoft Visual C++ Compiler for Python 2.7. Since it requires vcvarsall.bat file. This file is no where in Visual studio Community 2015, but it was in Microsoft Visual C++ Compiler for Python 2.7. I also added its path into my environment variables but it also did not work. Then I un-install python 3.4.2 and deleted all the folders of python, and installed python 2.7.

In my case I didn't have to do anything so drastic as uninstalling Git as per some of the answers here; I just had to use the command line instead of Visual Studio.

Open up cmd at your solution's root and enter:

git pull

You will then be told exactly what the issue is. In my case it told me that I had uncommitted changes that would have been overwritten and that I needed to commit them before I could continue.

Once I had done this the pull succeeded, and I could resolve the conflict in the merge tool.

TLDR

Use the command line instead of Visual Studio to get a more complete error message.

First of all, make sure the Text is enabled, then delete your tags, and then the content.

myText.config(state=NORMAL)
myText.tag_delete ("myTags")
myText.delete(1.0, END)

When the Text is "DISABLE", the delete does not work because the Text field is in read-only mode.

If you are using a Form Control, you can get the same property as ActiveX by using OLEFormat.Object property of the Shape Object. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.

Dim opt As OptionButton

With Sheets("Sheet1") ' Try to be always explicit
    Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
    Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With

But then again, you really don't need to know the value.
If you use Form Control, you associate a Macro or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.

For example you have 2 Form Control Option Buttons.

Sub CheckOptions()
    Select Case Application.Caller
    Case "Option Button 1"
    ' Action for option button 1
    Case "Option Button 2"
    ' Action for option button 2
    End Select
End Sub

In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller.
This way, no need to check whether the option button value is true or false.

I wrote a little query to find permission of a user on a specific database.

The permissions of fixed database roles do not appear in sys.database_permissions. Therefore, database principals may have additional permissions not listed here.

I does not prefer

    EXECUTE AS USER = 'userName';
    SELECT * FROM fn_my_permissions(NULL, 'DATABASE') 

Because it's just retrieving which permissions the user has not where they come from!

Maybe i find out how to join the fixed database roles permission granted for the user one day...

A realtime priority thread can never be pre-empted by timer interrupts and runs at a higher priority than any other thread in the system. As such a CPU bound realtime priority thread can totally ruin a machine.

Creating realtime priority threads requires a privilege (SeIncreaseBasePriorityPrivilege) so it can only be done by administrative users.

For Vista and beyond, one option for applications that do require that they run at realtime priorities is to use the Multimedia Class Scheduler Service (MMCSS) and let it manage your threads priority. The MMCSS will prevent your application from using too much CPU time so you don't have to worry about tanking the machine.

I had this problem just now and I tried the require_once trick, but it would just echo the CSS above all my php code without actually applying the styles.

What I did to fix it, though, was wrap all my php in their own plain HTML templates. Just type out html in the first line of the document and pick the suggestion html:5 to get the HTML boilerplate, like you would when you're just starting a plain HTML doc. Then cut the closing body and html tags and paste them all the way down at the bottom, below the closing php tag to wrap your php code without actually changing anything. Finally, you can just put your plain old link to your stylesheet into the head of your HTML. Works just fine.

To sort the list of dictionaries by key='name':

list_of_dicts.sort(key=operator.itemgetter('name'))

To sort the list of dictionaries by key='age':

list_of_dicts.sort(key=operator.itemgetter('age'))

As JavaScript is a client-side language and PHP is a server-side language you would need to physically push the variable to the PHP script, by either including the variable on the page load of the PHP script (script.php?var=test), which really has nothing to do with JavaScript, or by passing the variable to the PHP via an AJAX/AHAH call each time the variable is changed.

If you did want to go down the second path, you'd be looking at XMLHttpRequest, or my preference, jQuerys Ajax calls: http://docs.jquery.com/Ajax

As suggeseted, the way to go is valgrind. It's a profiler that checks many aspects of the running performance of your application, including the usage of memory.

Running your application through Valgrind will allow you to verify if you forget to release memory allocated with malloc, if you free the same memory twice etc.

There is another option that hasn't been explored here: declaring Xerces dependencies in Maven as optional:

<dependency>
   <groupId>xerces</groupId>
   <artifactId>xercesImpl</artifactId>
   <version>...</version>
   <optional>true</optional>
</dependency>

Basically what this does is to force all dependents to declare their version of Xerces or their project won't compile. If they want to override this dependency, they are welcome to do so, but then they will own the potential problem.

This creates a strong incentive for downstream projects to:

• Make an active decision. Do they go with the same version of Xerces or use something else?
• Actually test their parsing (e.g. through unit testing) and classloading as well as not to clutter up their classpath.

Not all developers keep track of newly introduced dependencies (e.g. with mvn dependency:tree). This approach will immediately bring the matter to their attention.

It works quite well at our organization. Before its introduction, we used to live in the same hell the OP is describing.

Do not use forward slashes at the beginning of path components, except when refering to the root directory:

os.path.join('/home/build/test/sandboxes', todaystr, 'new_sandbox')

see also: http://docs.python.org/library/os.path.html#os.path.join

You use ttk.Frame, bg option does not work for it. You should create style and apply it to the frame.

from tkinter import *
from tkinter.ttk import * 

root = Tk()

s = Style()
s.configure('My.TFrame', background='red')

mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()

Just simple modification of @silgon answer:

while true; do 
  inotifywait -r -e modify,create,delete /directory
  rsync -avz /directory /target
done

(@silgon version sometimes crashes on Ubuntu 16 if you run it in cron)

An unsigned application cannot be installed. When we run directly from eclipse, that apk is signed with debugger key and can be found in bin\ folder of the project. You can use that for test purpose distribution also.

Hi I have the same issue,

I write this vbscipt to create another CSV file. The new CSV file will have a space in font of each field, so excel will understand it as text.

So you create a .vbs file with the code below (for example Modify_CSV.vbs), save and close it. Drag and Drop your original file to your vbscript file. It will create a new file with "SPACE_ADDED" to file name in the same location.

Set objArgs = WScript.Arguments

Set objFso = createobject("scripting.filesystemobject")

dim objTextFile
dim arrStr ' an array to hold the text content
dim sLine  ' holding text to write to new file

'Looping through all dropped file
For t = 0 to objArgs.Count - 1
    ' Input Path
    inPath = objFso.GetFile(wscript.arguments.item(t))

    ' OutPut Path
    outPath = replace(inPath, objFso.GetFileName(inPath), left(objFso.GetFileName(inPath), InStrRev(objFso.GetFileName(inPath),".") - 1) & "_SPACE_ADDED.csv")

    ' Read the file
    set objTextFile = objFso.OpenTextFile(inPath)


    'Now Creating the file can overwrite exiting file
    set aNewFile = objFso.CreateTextFile(outPath, True) 
    aNewFile.Close  

    'Open the file to appending data
    set aNewFile = objFso.OpenTextFile(outPath, 8) '2=Open for writing 8 for appending

    ' Reading data and writing it to new file
    Do while NOT objTextFile.AtEndOfStream
        arrStr = split(objTextFile.ReadLine,",")

        sLine = ""  'Clear previous data

        For i=lbound(arrStr) to ubound(arrStr)
            sLine = sLine + " " + arrStr(i) + ","
        Next

        'Writing data to new file
        aNewFile.WriteLine left(sLine, len(sLine)-1) 'Get rid of that extra comma from the loop


    Loop

    'Closing new file
    aNewFile.Close  

Next ' This is for next file

set aNewFile=nothing
set objFso = nothing
set objArgs = nothing
