I was also getting the same error, the WCF was working properly for me when i was using it in the Dev Environment with my credentials, but when someone else was using it in TEST, it was throwing the same error. I did a lot of research, and then instead of doing config updates, handled an exception in the WCF method with the help of fault exception. Also the identity for the WCF needs to be set with the same credentials which are having access in the database, someone might have changed your authority. Please find below the code for the same:

 [ServiceContract]
public interface IService1
{
    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    ForDataset GetCCDBdata();

    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    string GetCCDBdataasXMLstring();


    //[OperationContract]
    //string GetData(int value);

    //[OperationContract]
    //CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
}

  [DataContract]
public class ServiceData
{
    [DataMember]
    public bool Result { get; set; }
    [DataMember]
    public string ErrorMessage { get; set; }
    [DataMember]
    public string ErrorDetails { get; set; }
}

in your service1.svc.cs you can use this in the catch block:

 catch (Exception ex)
        {
            myServiceData.Result = false;
            myServiceData.ErrorMessage = "unforeseen error occured. Please try later.";
            myServiceData.ErrorDetails = ex.ToString();
            throw new FaultException<ServiceData>(myServiceData, ex.ToString());
        }

And use this in the Client application like below code:

  ConsoleApplicationWCFClient.CCDB_HIG_service.ForDataset ds = obj.GetCCDBdata();

            string str = obj.GetCCDBdataasXMLstring();

        }

        catch (FaultException<ConsoleApplicationWCFClient.CCDB_HIG_service.ServiceData> Fex)
      {
          Console.WriteLine("ErrorMessage::" + Fex.Detail.ErrorMessage + Environment.NewLine);
          Console.WriteLine("ErrorDetails::" + Environment.NewLine + Fex.Detail.ErrorDetails);
          Console.ReadLine();
      }

Just try this, it will help for sure to get the exact issue.

You have to specify 0 (meaning false) or 1 (meaning true) as the default. Here is an example:

create table mytable (
     mybool boolean not null default 0
);

FYI: boolean is an alias for tinyint(1).

Here is the proof:

mysql> create table mytable (
    ->          mybool boolean not null default 0
    ->     );
Query OK, 0 rows affected (0.35 sec)

mysql> insert into mytable () values ();
Query OK, 1 row affected (0.00 sec)

mysql> select * from mytable;
+--------+
| mybool |
+--------+
|      0 |
+--------+
1 row in set (0.00 sec)

FYI: My test was done on the following version of MySQL:

mysql> select version();
+----------------+
| version()      |
+----------------+
| 5.0.18-max-log |
+----------------+
1 row in set (0.00 sec)

I had the same error when was trying to update linked table.

The issue was that linked table had no PRIMARY KEY.

After adding primary key constraint on database side and re linking this table to access problem was solved.

Hope it will help somebody.

The reason why @Resource(name = "{your child class name}") works but @Autowired sometimes don't work is because of the difference of their Matching sequence

Matching sequence of @Autowire
Type, Qualifier, Name

Matching sequence of @Resource
Name, Type, Qualifier

The more detail explanation can be found here:
Inject and Resource and Autowired annotations

In this case, different child class inherited from the parent class or interface confuses @Autowire, because they are from same type; As @Resource use Name as first matching priority , it works.

mysql> GRANT ALL ON *.* to root@'192.168.1.%' IDENTIFIED BY 'your-root-password';  

The wildcard character is a "%" instead of an "*"

String.split() can also accept a regular expression:

input.split(/[ ,]+/);

This particular regex splits on a sequence of one or more commas or spaces, so that e.g. multiple consecutive spaces or a comma+space sequence do not produce empty elements in the results.

It can't be done, either manually or progamatically. This is because the color behind every slide master is white. If you set your background to 100% transparent, it will print as white.

The best you could do is design your slide with all the stuff you want, group everything you want to appear in the transparent image and then right-click/save as picture/.PNG (or you could do that with a macro as well). In this way you would retain transparency.

Here's an example of how to export all slides' shapes to seperate PNG files. Note:

1. This does not get any background shapes on the Slide Master.
2. Resulting PNGs will not be the same size as each other, depending on where the shapes are located on each slide.

3. This uses a depreciated function, namely Shape.Export. This means that while the function is still available up to PowerPoint 2010, it may be removed from PowerPoint VBA later.

   Sub PrintShapesToPng()
       Dim ap As Presentation: Set ap = ActivePresentation
       Dim sl As slide
       Dim shGroup As ShapeRange
       For Each sl In ap.Slides
           ActiveWindow.View.GotoSlide (sl.SlideIndex)
           sl.Shapes.SelectAll
           Set shGroup = ActiveWindow.Selection.ShapeRange
           shGroup.Export ap.Path & "\Slide" & sl.SlideIndex & ".png", _
                               ppShapeFormatPNG, , , ppRelativeToSlide
       Next
   End Sub

This can be easily solved with the the utility make_axes_locatable. I provide a minimal example that shows how this works and should be readily adaptable:

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

import numpy as np

m1 = np.random.rand(3, 3)
m2 = np.arange(0, 3*3, 1).reshape((3, 3))

fig = plt.figure(figsize=(16, 12))
ax1 = fig.add_subplot(121)
im1 = ax1.imshow(m1, interpolation='None')

divider = make_axes_locatable(ax1)
cax = divider.append_axes('right', size='5%', pad=0.05)
fig.colorbar(im1, cax=cax, orientation='vertical')

ax2 = fig.add_subplot(122)
im2 = ax2.imshow(m2, interpolation='None')

divider = make_axes_locatable(ax2)
cax = divider.append_axes('right', size='5%', pad=0.05)
fig.colorbar(im2, cax=cax, orientation='vertical');

this is simple solution for your question

LatLng coordinate = new LatLng(lat, lng);
CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(coordinate, 5);
map.animateCamera(yourLocation);

Here is another way. No intermediate variables are saved.

We used this to de-duplicate results from a variety of overlapping queries.

$input = array_map("unserialize", array_unique(array_map("serialize", $input)));

You just do CSS changes for parent div

.parent-div { 
        text-align: center;
        display: block;
}

Use the below code for converting XML to JSON.

var json = new JavaScriptSerializer().Serialize(obj);

If you're willing to adopt the practice of always using curly braces in your if statements,

Your macro would simply be missing the last semicolon:

#define MACRO(X,Y)                       \
cout << "1st arg is:" << (X) << endl;    \
cout << "2nd arg is:" << (Y) << endl;    \
cout << "Sum is:" << ((X)+(Y)) << endl

Example 1: (compiles)

if (x > y) {
    MACRO(x, y);
}
do_something();

Example 2: (compiles)

if (x > y) {
    MACRO(x, y);
} else {
    MACRO(y - x, x - y);
}

Example 3: (doesn't compile)

do_something();
MACRO(x, y)
do_something();

Flex Solution

It is perfectly fine if you want to go with the display: table-cell solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;. flex is something which has a decent support.

.wrap {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  border: 1px solid #aaa;_x000D_
  margin: 10px;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
  align-self: flex-end;_x000D_
}

<div class="wrap">_x000D_
  <span>Align me to the bottom</span>_x000D_
</div>

In the above example, we first set the parent element to display: flex; and later, we use align-self to flex-end. This helps you push the item to the end of the flex parent.

Old Solution (Valid if you are not willing to use flex)

If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell; with vertical-align: bottom; is enough

div {_x000D_
  display: table-cell;_x000D_
  vertical-align: bottom;_x000D_
  border: 1px solid #f00;_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_
}

<div>Hello</div>

You can use a very nice tool called Stetho by adding this to build.gradle file:

compile 'com.facebook.stetho:stetho:1.4.1'

And initialized it inside your Application or Activity onCreate() method:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Stetho.initializeWithDefaults(this);
    setContentView(R.layout.activity_main);
}

Then you can view the db records in chrome in the address:

See Introduction to the POM

finalName is created as:

<build>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

One of the solutions is to add own property:

<properties>
    <finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
 </build>

And now try:

mvn -DfinalName=build clean package

Simple one liner

[].sort().pop()

You need to do something like this:

PrintStream out = new PrintStream(new FileOutputStream("output.txt"));
System.setOut(out);

The second statement is the key. It changes the value of the supposedly "final" System.out attribute to be the supplied PrintStream value.

There are analogous methods (setIn and setErr) for changing the standard input and error streams; refer to the java.lang.System javadocs for details.

A more general version of the above is this:

PrintStream out = new PrintStream(
        new FileOutputStream("output.txt", append), autoFlush);
System.setOut(out);

If append is true, the stream will append to an existing file instead of truncating it. If autoflush is true, the output buffer will be flushed whenever a byte array is written, one of the println methods is called, or a \n is written.

I'd just like to add that it is usually a better idea to use a logging subsystem like Log4j, Logback or the standard Java java.util.logging subsystem. These offer fine-grained logging control via runtime configuration files, support for rolling log files, feeds to system logging, and so on.

Alternatively, if you are not "logging" then consider the following:

• With typical shells, you can redirecting standard output (or standard error) to a file on the command line; e.g.

  $ java MyApp > output.txt   
  

  For more information, refer to a shell tutorial or manual entry.

• You could change your application to use an out stream passed as a method parameter or via a singleton or dependency injection rather than writing to System.out.

Changing System.out may cause nasty surprises for other code in your JVM that is not expecting this to happen. (A properly designed Java library will avoid depending on System.out and System.err, but you could be unlucky.)

Simple indexOf search

var $rows = $('#table tr');
$('#search').keyup(function() {
    var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();

    $rows.show().filter(function() {
        var text = $(this).text().replace(/\s+/g, ' ').toLowerCase();
        return !~text.indexOf(val);
    }).hide();
});

Demo: http://jsfiddle.net/7BUmG/2/

Regular expression search

More advanced functionality using regular expressions will allow you to search words in any order in the row. It will work the same if you type apple green or green apple:

var $rows = $('#table tr');
$('#search').keyup(function() {

    var val = '^(?=.*\\b' + $.trim($(this).val()).split(/\s+/).join('\\b)(?=.*\\b') + ').*$',
        reg = RegExp(val, 'i'),
        text;

    $rows.show().filter(function() {
        text = $(this).text().replace(/\s+/g, ' ');
        return !reg.test(text);
    }).hide();
});

Demo: http://jsfiddle.net/dfsq/7BUmG/1133/

Debounce

When you implement table filtering with search over multiple rows and columns it is very important that you consider performance and search speed/optimisation. Simply saying you should not run search function on every single keystroke, it's not necessary. To prevent filtering to run too often you should debounce it. Above code example will become:

$('#search').keyup(debounce(function() {
    var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();
    // etc...
}, 300));

You can pick any debounce implementation, for example from Lodash _.debounce, or you can use something very simple like I use in next demos (debounce from here): http://jsfiddle.net/7BUmG/6230/ and http://jsfiddle.net/7BUmG/6231/.

GNU mailutils's 'mail' command doesn't let you do this (easily at least). But If you install 'heirloom-mailx', its mail command (mailx) has the '-r' option to override the default '$USER@$HOSTNAME' from field.

Works for 'mailx' but not 'mail'.

$ ls -l /usr/bin/mail

You can use actions for short event handlers:

btnSubmit.Click += (sender, e) => MessageBox.Show("You clicked save!");

library is an object, not an array. You push things onto arrays. Unlike PHP, Javascript makes a distinction.

Your code tries to make a string that looks like the source code for a key-value pair, and then "push" it onto the object. That's not even close to how it works.

What you want to do is add a new key-value pair to the object, where the key is the title and the value is another object. That looks like this:

library[title] = {"foregrounds" : foregrounds, "backgrounds" : backgrounds};

"JSON object" is a vague term. You must be careful to distinguish between an actual object in memory in your program, and a fragment of text that is in JSON format.

How does it work?

When a JSF view (Facelets/JSP file) get built/restored, a JSF component tree will be produced. At that moment, the view build time, all binding attributes are evaluated (along with id attribtues and taghandlers like JSTL). When the JSF component needs to be created before being added to the component tree, JSF will check if the binding attribute returns a precreated component (i.e. non-null) and if so, then use it. If it's not precreated, then JSF will autocreate the component "the usual way" and invoke the setter behind binding attribute with the autocreated component instance as argument.

In effects, it binds a reference of the component instance in the component tree to a scoped variable. This information is in no way visible in the generated HTML representation of the component itself. This information is in no means relevant to the generated HTML output anyway. When the form is submitted and the view is restored, the JSF component tree is just rebuilt from scratch and all binding attributes will just be re-evaluated like described in above paragraph. After the component tree is recreated, JSF will restore the JSF view state into the component tree.

Component instances are request scoped!

Important to know and understand is that the concrete component instances are effectively request scoped. They're newly created on every request and their properties are filled with values from JSF view state during restore view phase. So, if you bind the component to a property of a backing bean, then the backing bean should absolutely not be in a broader scope than the request scope. See also JSF 2.0 specitication chapter 3.1.5:

3.1.5 Component Bindings

...

Component bindings are often used in conjunction with JavaBeans that are dynamically instantiated via the Managed Bean Creation facility (see Section 5.8.1 “VariableResolver and the Default VariableResolver”). It is strongly recommend that application developers place managed beans that are pointed at by component binding expressions in “request” scope. This is because placing it in session or application scope would require thread-safety, since UIComponent instances depends on running inside of a single thread. There are also potentially negative impacts on memory management when placing a component binding in “session” scope.

Otherwise, component instances are shared among multiple requests, possibly resulting in "duplicate component ID" errors and "weird" behaviors because validators, converters and listeners declared in the view are re-attached to the existing component instance from previous request(s). The symptoms are clear: they are executed multiple times, one time more with each request within the same scope as the component is been bound to.

And, under heavy load (i.e. when multiple different HTTP requests (threads) access and manipulate the very same component instance at the same time), you may face sooner or later an application crash with e.g. Stuck thread at UIComponent.popComponentFromEL, or Java Threads at 100% CPU utilization using richfaces UIDataAdaptorBase and its internal HashMap, or even some "strange" IndexOutOfBoundsException or ConcurrentModificationException coming straight from JSF implementation source code while JSF is busy saving or restoring the view state (i.e. the stack trace indicates saveState() or restoreState() methods and like).

Using binding on a bean property is bad practice

Regardless, using binding this way, binding a whole component instance to a bean property, even on a request scoped bean, is in JSF 2.x a rather rare use case and generally not the best practice. It indicates a design smell. You normally declare components in the view side and bind their runtime attributes like value, and perhaps others like styleClass, disabled, rendered, etc, to normal bean properties. Then, you just manipulate exactly that bean property you want instead of grabbing the whole component and calling the setter method associated with the attribute.

In cases when a component needs to be "dynamically built" based on a static model, better is to use view build time tags like JSTL, if necessary in a tag file, instead of createComponent(), new SomeComponent(), getChildren().add() and what not. See also How to refactor snippet of old JSP to some JSF equivalent?

Or, if a component needs to be "dynamically rendered" based on a dynamic model, then just use an iterator component (<ui:repeat>, <h:dataTable>, etc). See also How to dynamically add JSF components.

Composite components is a completely different story. It's completely legit to bind components inside a <cc:implementation> to the backing component (i.e. the component identified by <cc:interface componentType>. See also a.o. Split java.util.Date over two h:inputText fields representing hour and minute with f:convertDateTime and How to implement a dynamic list with a JSF 2.0 Composite Component?

Only use binding in local scope

However, sometimes you'd like to know about the state of a different component from inside a particular component, more than often in use cases related to action/value dependent validation. For that, the binding attribute can be used, but not in combination with a bean property. You can just specify an in the local EL scope unique variable name in the binding attribute like so binding="#{foo}" and the component is during render response elsewhere in the same view directly as UIComponent reference available by #{foo}. Here are several related questions where such a solution is been used in the answer:

• Validate input as required only if certain command button is pressed
• How to render a component only if another component is not rendered?
• JSF 2 dataTable row index without dataModel
• Primefaces dependent selectOneMenu and required="true"
• Validate a group of fields as required when at least one of them is filled
• How to change css class for the inputfield and label when validation fails?

I had the same problem while installing gensim on windows. Gensim is dependent on scipy and scipy on numpy. Making all three work is real pain. It took me a lot of time to make all there work on same time.

Solution: If you are using windows make sure you install numpy+mkl instead of just numpy. If you have already installed scipy and numpy, uninstall then using "pip uninstall scipy" and "pip uninstall numpy"

Then download numpy-1.13.1+mkl-cp34-cp34m-win32.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy and install using pip install numpy-1.13.1+mkl-cp34-cp34m-win32.wh Note: in cp34-cp34m 34 represent the version of python you are using, so download the relevant version.

Now download scipy from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy (appropriate version for your python and system) and install using "pip install scipy-0.19.1-cp34-cp34m-win32.whl"

Your numpy and Scipy both should work now. These binaries by Christoph Gohlke makes it very easy to install python packages on windows. But make sure you download all the dependent packages from there.

Use following in your CSS

div {
    -webkit-transform: rotate(90deg); /* Safari and Chrome */
    -moz-transform: rotate(90deg);   /* Firefox */
    -ms-transform: rotate(90deg);   /* IE 9 */
    -o-transform: rotate(90deg);   /* Opera */
    transform: rotate(90deg);
}

Here is a method to get lines between two line numbers in a file:

import sys

def file_line(name,start=1,end=sys.maxint):
    lc=0
    with open(s) as f:
        for line in f:
            lc+=1
            if lc>=start and lc<=end:
                yield line


s='/usr/share/dict/words'
l1=list(file_line(s,235880))
l2=list(file_line(s,1,10))
print l1
print l2

Output:

['Zyrian\n', 'Zyryan\n', 'zythem\n', 'Zythia\n', 'zythum\n', 'Zyzomys\n', 'Zyzzogeton\n']
['A\n', 'a\n', 'aa\n', 'aal\n', 'aalii\n', 'aam\n', 'Aani\n', 'aardvark\n', 'aardwolf\n', 'Aaron\n']

Just call it with one parameter to get from line n -> EOF

You can use a StringWriter to write values to a string. It provides a stream-like syntax (though does not derive from Stream) which works with an underlying StringBuilder.

Both approaches behave differently if you use a spied object (annotated with @Spy) instead of a mock (annotated with @Mock):

• when(...) thenReturn(...) makes a real method call just before the specified value will be returned. So if the called method throws an Exception you have to deal with it / mock it etc. Of course you still get your result (what you define in thenReturn(...))

• doReturn(...) when(...) does not call the method at all.

Example:

public class MyClass {
     protected String methodToBeTested() {
           return anotherMethodInClass();
     }

     protected String anotherMethodInClass() {
          throw new NullPointerException();
     }
}

Test:

@Spy
private MyClass myClass;

// ...

// would work fine
doReturn("test").when(myClass).anotherMethodInClass();

// would throw a NullPointerException
when(myClass.anotherMethodInClass()).thenReturn("test");

this also worked for me , thanks a lot

changing java proxy settings to direct connection did not fix my issue.

What worked for me:

Run "Configure Java" as administrator.
Go to Advanced
Scroll to bottom
Under: "Advanced Security Settings" uncheck "Use SSL 2.0 compatible ClientHello format"
Save

If you are doing VANILLA plain JavaScript without jQuery, then you must use (Internet Explorer 9 or later):

document.addEventListener("DOMContentLoaded", function(event) {
    // Your code to run since DOM is loaded and ready
});

Above is the equivalent of jQuery .ready:

$(document).ready(function() {
    console.log("Ready!");
});

Which ALSO could be written SHORTHAND like this, which jQuery will run after the ready even occurs.

$(function() {
    console.log("ready!");
});

NOT TO BE CONFUSED with BELOW (which is not meant to be DOM ready):

DO NOT use an IIFE like this that is self executing:

 Example:

(function() {
   // Your page initialization code here  - WRONG
   // The DOM will be available here   - WRONG
})();

This IIFE will NOT wait for your DOM to load. (I'm even talking about latest version of Chrome browser!)

I ran : npm i gulp-sass@latest --save-dev

That did the magic for me

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_
    return <div>_x000D_
      <MyClickable name="a" index={0} isActive={ this.state.activeIndex===0 } onClick={ this.handleClick } />_x000D_
      <MyClickable name="b" index={1} isActive={ this.state.activeIndex===1 } onClick={ this.handleClick }/>_x000D_
      <MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
    </div>_x000D_
  }_x000D_
}_x000D_
_x000D_
class MyClickable extends React.Component {_x000D_
  handleClick = () => this.props.onClick(this.props.index)_x000D_
  _x000D_
  render() {_x000D_
    return <button_x000D_
      type='button'_x000D_
      className={_x000D_
        this.props.isActive ? 'active' : 'album'_x000D_
      }_x000D_
      onClick={ this.handleClick }_x000D_
    >_x000D_
      <span>{ this.props.name }</span>_x000D_
    </button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Container />, document.getElementById('app'))

button {_x000D_
  display: block;_x000D_
  margin-bottom: 1em;_x000D_
}_x000D_
_x000D_
.album>span:after {_x000D_
  content: ' (an album)';_x000D_
}_x000D_
_x000D_
.active {_x000D_
  font-weight: bold;_x000D_
}_x000D_
_x000D_
.active>span:after {_x000D_
  content: ' ACTIVE';_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react-dom.min.js"></script>_x000D_
<div id="app"></div>

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

That's 32 hex characters - 1 hex character is 4 bits.

move.CompleteMove() does not return a value (perhaps it just prints something). Any method that does not return a value returns None, and you have assigned None to self.values.

Here is an example of this:

>>> def hello(x):
...    print x*2
...
>>> hello('world')
worldworld
>>> y = hello('world')
worldworld
>>> y
>>>

You'll note y doesn't print anything, because its None (the only value that doesn't print anything on the interactive prompt).

Working for me on IE:

<script type="text/javascript">
  var WinNetwork = new ActiveXObject("WScript.Network");
  document.write(WinNetwork.UserName);
</script>

...but ActiveX controls needs to be on in security settings.

I think this is because you are using client software and not the server.

• mysql is client
• mysqld is the server

Try: sudo service mysqld start

To check that service is running use: ps -ef | grep mysql | grep -v grep.

Uninstalling:

sudo apt-get purge mysql-server
sudo apt-get autoremove
sudo apt-get autoclean

Re-Installing:

sudo apt-get update
sudo apt-get install mysql-server

Backup entire folder before doing this:

sudo rm /etc/apt/apt.conf.d/50unattended-upgrades*
sudo apt-get update
sudo apt-get upgrade

You can use:

$ jq 'keys' file.json

$ cat file.json:
{ "Archiver-Version" : "Plexus Archiver", "Build-Id" : "", "Build-Jdk" : "1.7.0_07", "Build-Number" : "", "Build-Tag" : "", "Built-By" : "cporter", "Created-By" : "Apache Maven", "Implementation-Title" : "northstar", "Implementation-Vendor-Id" : "com.test.testPack", "Implementation-Version" : "testBox", "Manifest-Version" : "1.0", "appname" : "testApp", "build-date" : "02-03-2014-13:41", "version" : "testBox" }

$ jq 'keys' file.json
[
  "Archiver-Version",
  "Build-Id",
  "Build-Jdk",
  "Build-Number",
  "Build-Tag",
  "Built-By",
  "Created-By",
  "Implementation-Title",
  "Implementation-Vendor-Id",
  "Implementation-Version",
  "Manifest-Version",
  "appname",
  "build-date",
  "version"
]

UPDATE: To create a BASH array using these keys:

Using BASH 4+:

mapfile -t arr < <(jq -r 'keys[]' ms.json)

On older BASH you can do:

arr=()
while IFS='' read -r line; do
   arr+=("$line")
done < <(jq 'keys[]' ms.json)

Then print it:

printf "%s\n" ${arr[@]}

"Archiver-Version"
"Build-Id"
"Build-Jdk"
"Build-Number"
"Build-Tag"
"Built-By"
"Created-By"
"Implementation-Title"
"Implementation-Vendor-Id"
"Implementation-Version"
"Manifest-Version"
"appname"
"build-date"
"version"

Something along the lines of:

yourString = yourString.replace ( /[^0-9]/g, '' );

With an editable div you can use the method document.execCommand (more details) to easily provide the support for the tags you specified and for some other functionality..

#text {_x000D_
    width : 500px;_x000D_
 min-height : 100px;_x000D_
 border : 2px solid;_x000D_
}

<div id="text" contenteditable="true"></div>_x000D_
<button onclick="document.execCommand('bold');">toggle bold</button>_x000D_
<button onclick="document.execCommand('italic');">toggle italic</button>_x000D_
<button onclick="document.execCommand('underline');">toggle underline</button>

The SQL Server Management Studio has implicit commit turned on, so all statements that are executed are implicitly commited.

This might be a scary thing if you come from an Oracle background where the default is to not have commands commited automatically, but it's not that much of a problem.

If you still want to use ad-hoc transactions, you can always execute

BEGIN TRANSACTION

within SSMS, and than the system waits for you to commit the data.

If you want to replicate the Oracle behaviour, and start an implicit transaction, whenever some DML/DDL is issued, you can set the SET IMPLICIT_TRANSACTIONS checkbox in

Tools -> Options -> Query Execution -> SQL Server -> ANSI

%date% will give you the date.

%time% will give you the time.

The date and time /t commands may give you more detail.

The magic method __getitem__ is basically used for accessing list items, dictionary entries, array elements etc. It is very useful for a quick lookup of instance attributes.

Here I am showing this with an example class Person that can be instantiated by 'name', 'age', and 'dob' (date of birth). The __getitem__ method is written in a way that one can access the indexed instance attributes, such as first or last name, day, month or year of the dob, etc.

import copy

# Constants that can be used to index date of birth's Date-Month-Year
D = 0; M = 1; Y = -1

class Person(object):
    def __init__(self, name, age, dob):
        self.name = name
        self.age = age
        self.dob = dob

    def __getitem__(self, indx):
        print ("Calling __getitem__")
        p = copy.copy(self)

        p.name = p.name.split(" ")[indx]
        p.dob = p.dob[indx] # or, p.dob = p.dob.__getitem__(indx)
        return p

Suppose one user input is as follows:

p = Person(name = 'Jonab Gutu', age = 20, dob=(1, 1, 1999))

With the help of __getitem__ method, the user can access the indexed attributes. e.g.,

print p[0].name # print first (or last) name
print p[Y].dob  # print (Date or Month or ) Year of the 'date of birth'

Like said previously, you can choose between a lot of choices, take a look at all those choices: http://kkovacs.eu/cassandra-vs-mongodb-vs-couchdb-vs-redis

What I suggest is to find your best combination: MySQL + Memcache is really great if you need ACID and you want to join some tables MongoDB + Redis is perfect for document store Neo4J is perfect for graph database

What i do: I start with MySQl + Memcache because I'm use to, then I start using others database framework. In a single project, you can combine MySQL and MongoDB for instance !

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

Do you mean the zip command-line tool or the Finder's Compress command?

For zip, you can try the --data-fork option. If that doesn't do it, you might try --no-extra, although that seems to ignore other file metadata that might be valuable, like uid/gid and file times.

For the Finder's Compress command, I don't believe there are any options to control its behavior. It's for the simple case.

The other tool, and maybe the one that the Finder actually uses under the hood, is ditto. With the -c -k options, it creates zip archives. With this tool, you can experiment with --norsrc, --noextattr, --noqtn, --noacl and/or simply leave off the --sequesterRsrc option (which, according to the man page, may be responsible for the __MACOSX subdirectory). Although, perhaps the absence of --sequesterRsrc simply means to use AppleDouble format, which would create ._ files all over the place instead of one __MACOSX directory.

Update Nov 2015:

Sometime in late 2015, the Google Developers Console interface was overhauled again. For the new interface:

1. Select your project from the toolbar.

2. Open the "Gallery" using hamburger menu icon on the left side of the toolbar and select 'API Manager'.

3. Click 'Credentials' in the left-hand navigation.

Alternatively, you can click 'Switch to old console' under the the three-dot menu (right side of the toolbar), then follow the instructions below.

For the NEW (edit: OLD) Google Developers Console:

You get your 'Developer key' (a.k.a. API key) on the same screen where you get your client ID/secret. (This is the 'Credentials' screen, which can be found under 'APIs & auth' in the left nav.)

Below your client ID keys, there is a section titled 'Public API access'. If there are no keys in this this section, click 'Create new Key'. Your developer key is the 'API key' specified here.

I took Mr. Fooz's code and also added Arlen's solution too and here are the timings that I've gotten for Octave:

clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V);         end; toc % 7.0 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 6.4 s
tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 5.5 s
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 6.6 s
tic; for i=1:N, V1 = V/norm(V);         end; toc % 7.1 s
tic; for i=1:N, d = 1/norm(V); V1 = V*d;end; toc % 4.7 s

Then, because of something I'm currently looking at, I tested out this code for ensuring that each row sums to 1:

clc; clear all;
m = 2048;
V = rand(m);
N = 100;
tic; for i=1:N, V1 = V ./ (sum(V,2)*ones(1,m));                end; toc % 8.2 s
tic; for i=1:N, V2 = bsxfun(@rdivide, V, sum(V,2));            end; toc % 5.8 s
tic; for i=1:N, V3 = bsxfun(@rdivide, V, V*ones(m,1));         end; toc % 5.7 s
tic; for i=1:N, V4 = V ./ (V*ones(m,m));                       end; toc % 77.5 s
tic; for i=1:N, d = 1./sum(V,2);V5 = bsxfun(@times, V, d);     end; toc % 2.83 s
tic; for i=1:N, d = 1./(V*ones(m,1));V6 = bsxfun(@times, V, d);end; toc % 2.75 s
tic; for i=1:N, V1 = V ./ (sum(V,2)*ones(1,m));                end; toc % 8.2 s

The easiest way to solve the problem is to group the elements based on their value, and then pick a representative of the group if there are more than one element in the group. In LINQ, this translates to:

var query = lst.GroupBy(x => x)
              .Where(g => g.Count() > 1)
              .Select(y => y.Key)
              .ToList();

If you want to know how many times the elements are repeated, you can use:

var query = lst.GroupBy(x => x)
              .Where(g => g.Count() > 1)
              .Select(y => new { Element = y.Key, Counter = y.Count() })
              .ToList();

This will return a List of an anonymous type, and each element will have the properties Element and Counter, to retrieve the information you need.

And lastly, if it's a dictionary you are looking for, you can use

var query = lst.GroupBy(x => x)
              .Where(g => g.Count() > 1)
              .ToDictionary(x => x.Key, y => y.Count());

This will return a dictionary, with your element as key, and the number of times it's repeated as value.

You can also accomplish this using the sqldf package as shown below:

library(sqldf)

x <- read.table(text='Name     Month  Rate1     Rate2
Aira       1      12        23
                Aira       2      18        73
                Aira       3      19        45
                Ben        1      53        19
                Ben        2      22        87
                Ben        3      19        45
                Cat        1      22        87
                Cat        2      67        43
                Cat        3      45        32', header=TRUE)

sqldf("
select 
  Name
  ,avg(Rate1) as Rate1_float
  ,avg(Rate2) as Rate2_float
  ,avg(Rate1) as Rate1
  ,avg(Rate2) as Rate2
from x
group by 
  Name
")

#  Name Rate1_float Rate2_float Rate1 Rate2
#1 Aira    16.33333    47.00000    16    47
#2  Ben    31.33333    50.33333    31    50
#3  Cat    44.66667    54.00000    44    54

I am a recent convert to dplyr as shown in other answers, but sqldf is nice as most data analysts/data scientists/developers have at least some fluency in SQL. In this way, I think it tends to make for more universally readable code than dplyr or other solutions presented above.

UPDATE: In responding to the comment below, I attempted to update the code as shown above. However, the behavior was not as I expected. It seems that the column definition (i.e. int vs float) is only carried through when the column alias matches the original column name. When you specify a new name, the aggregate column is returned without rounding.

You can do it this way to return you a list of absolute path files.

def list_files_recursive(path):
    """
    Function that receives as a parameter a directory path
    :return list_: File List and Its Absolute Paths
    """

    import os

    files = []

    # r = root, d = directories, f = files
    for r, d, f in os.walk(path):
        for file in f:
            files.append(os.path.join(r, file))

    lst = [file for file in files]
    return lst


if __name__ == '__main__':

    result = list_files_recursive('/tmp')
    print(result)

If after ./configure Makefile.in and Makefile.am are generated and make fail (by showing this following make: *** No targets specified and no makefile found. Stop.) so there is something not configured well, to solve it, first run "autoconf" commande to solve wrong configuration then re-run "./configure" commande and finally "make"

If you get the context via the parameter list of Configure in Startup.cs, You can instead do this:

public void Configure(IApplicationBuilder app, IHostingEnvironment env,  LoggerFactory loggerFactory,
    ApplicationDbContext context)
 {
      context.Database.Migrate();

Just delete /etc/ImageMagick/policy.xml file. E.g.

rm /etc/<ImageMagick_PATH>/policy.xml

For ImageMagick 6, it's:

sudo rm /etc/ImageMagick-6/policy.xml

To return a different view, you can specify the name of the view you want to return and model as follows:

return View("ViewName", yourModel);

if the view is in different folder under Views folder then use below absolute path:

return View("~/Views/FolderName/ViewName.aspx");

Map :

1. It processes one row at a time , very similar to map() method of MapReduce.
2. You return from the transformation after every row.

MapPartitions

1. It processes the complete partition in one go.
2. You can return from the function only once after processing the whole partition.
3. All intermediate results needs to be held in memory till you process the whole partition.
4. Provides you like setup() map() and cleanup() function of MapReduce

you can use the keyword 'In' and pass the List argument. e.g : findByInventoryIdIn

 List<AttributeHistory> findByValueIn(List<String> values);

Signed left shift Logically Simple if 1<<11 it will tends to 2048 and 2<<11 will give 4096

In java programming int a = 2 << 11;

// it will result in 4096

2<<11 = 2*(2^11) = 4096

I had a setup
with webpack using presets: ['es2015', 'stage-0']
and mocha that was running tests compiled by webpack.

To make my async/await in tests work all I had to do is use mocha with the --require babel-polyfill option:

mocha --require babel-polyfill

it's worked good for me

CREATE TABLE dbto.table_name like dbfrom.table_name;
insert into  dbto.table_name select * from dbfrom.table_name;

I made this into a jQuery function:

jQuery.fn.sortDivs = function sortDivs() {
    $("> div", this[0]).sort(dec_sort).appendTo(this[0]);
    function dec_sort(a, b){ return ($(b).data("sort")) < ($(a).data("sort")) ? 1 : -1; }
}

So you have a big div like "#boo" and all your little divs inside of there:

$("#boo").sortDivs();

You need the "? 1 : -1" because of a bug in Chrome, without this it won't sort more than 10 divs! http://blog.rodneyrehm.de/archives/14-Sorting-Were-Doing-It-Wrong.html

You can't directly edit your path to execute of a service. For that you can use sc command,

SC CONFIG ServiceName binPath= "Path of your file"

Eg:

sc config MongoDB binPath="I:\Programming\MongoDB\MongoDB\bin\mongod.exe --config I:\Programming\MongoDB\MongoDB\bin\mongod.cfg --service"

This is an old thread, but for reference it's important to note that disabling an input element's outline is not recommended as it hinders accessibility.

The outline property is there for a reason - providing users with a clear indication of keyboard focus. For further reading and additional sources about this subject see http://outlinenone.com/

You can do this by using @ViewChild for more info check this link

With type selector

child component

@Component({
  selector: 'child-cmp',
  template: '<p>child</p>'
})
class ChildCmp {
  doSomething() {}
}

parent component

@Component({
  selector: 'some-cmp',
  template: '<child-cmp></child-cmp>',
  directives: [ChildCmp]
})
class SomeCmp {

  @ViewChild(ChildCmp) child:ChildCmp;

  ngAfterViewInit() {
    // child is set
    this.child.doSomething();
  }
}

With string selector

child component

@Component({
  selector: 'child-cmp',
  template: '<p>child</p>'
})
class ChildCmp {
  doSomething() {}
}

parent component

@Component({
  selector: 'some-cmp',
  template: '<child-cmp #child></child-cmp>',
  directives: [ChildCmp]
})
class SomeCmp {

  @ViewChild('child') child:ChildCmp;

  ngAfterViewInit() {
    // child is set
    this.child.doSomething();
  }
}

Actually here is a better version - the old one failed if a folder name had a space in it.

  private String getJarFolder() {
    // get name and path
    String name = getClass().getName().replace('.', '/');
    name = getClass().getResource("/" + name + ".class").toString();
    // remove junk
    name = name.substring(0, name.indexOf(".jar"));
    name = name.substring(name.lastIndexOf(':')-1, name.lastIndexOf('/')+1).replace('%', ' ');
    // remove escape characters
    String s = "";
    for (int k=0; k<name.length(); k++) {
      s += name.charAt(k);
      if (name.charAt(k) == ' ') k += 2;
    }
    // replace '/' with system separator char
    return s.replace('/', File.separatorChar);
  }

As for failing with applets, you wouldn't usually have access to local files anyway. I don't know much about JWS but to handle local files might it not be possible to download the app.?

You need to specify the primary key as auto-increment

CREATE TABLE `momento_distribution`
  (
     `momento_id`       INT(11) NOT NULL AUTO_INCREMENT,
     `momento_idmember` INT(11) NOT NULL,
     `created_at`       DATETIME DEFAULT NULL,
     `updated_at`       DATETIME DEFAULT NULL,
     `unread`           TINYINT(1) DEFAULT '1',
     `accepted`         VARCHAR(10) NOT NULL DEFAULT 'pending',
     `ext_member`       VARCHAR(255) DEFAULT NULL,
     PRIMARY KEY (`momento_id`, `momento_idmember`),
     KEY `momento_distribution_FI_2` (`momento_idmember`),
     KEY `accepted` (`accepted`, `ext_member`)
  )
ENGINE=InnoDB
DEFAULT CHARSET=latin1$$

With regards to comment below, how about:

ALTER TABLE `momento_distribution`
  CHANGE COLUMN `id` `id` INT(11) NOT NULL AUTO_INCREMENT,
  DROP PRIMARY KEY,
  ADD PRIMARY KEY (`id`);

A PRIMARY KEY is a unique index, so if it contains duplicates, you cannot assign the column to be unique index, so you may need to create a new column altogether

Another alternative to 2 answers presented above. If you change your return type to object, you can return null, while at the same time cast the non-null return.

static object FindThing<T>(IList collection, int id)
{
    foreach T thing in collecion
    {
        if (thing.Id == id)
            return (T) thing;
    }
    return null;  // allowed now
}

The following worked for me after hours of trying

      $http.post("http://localhost:8080/yourresource", parameter, {headers: 
      {'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '*' } }).

However following code did not work, I am unclear as to why, hopefully someone can improve this answer.

          $http({   method: 'POST', url: "http://localhost:8080/yourresource", 
                    parameter, 
                    headers: {'Content-Type': 'application/json', 
                              'Access-Control-Allow-Origin': '*',
                              'Access-Control-Allow-Methods': 'POST'} 
                })

All you need:

table {
    border-collapse: separate;
    border-spacing: 0 1em;
}

That assumes you want a 1em vertical gap, and no horizontal gap. If you're doing this, you should probably also look at controlling your line-height.

Sort of weird that some of the answers people gave involve border-collapse: collapse, whose effect is the exact opposite of what the question asked for.

You should really use generics and the enhanced for loop for this:

Map<Integer, String> hm = new HashMap<>();
hm.put(0, "zero");
hm.put(1, "one");

for (Integer key : hm.keySet()) {
    System.out.println(key);
    System.out.println(hm.get(key));
}

http://ideone.com/sx3F0K

Or the entrySet() version:

Map<Integer, String> hm = new HashMap<>();
hm.put(0, "zero");
hm.put(1, "one");

for (Map.Entry<Integer, String> e : hm.entrySet()) {
    System.out.println(e.getKey());
    System.out.println(e.getValue());
}

Try this, it's simple and clear. I have found it from here : https://css-tricks.com/tinted-images-multiple-backgrounds/

.tinted-image {

  width: 300px;
  height: 200px;

  background: 
    /* top, transparent red */ 
    linear-gradient(
      rgba(255, 0, 0, 0.45), 
      rgba(255, 0, 0, 0.45)
    ),
    /* bottom, image */
    url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/3/owl1.jpg);
}

Syntax errors in the config file seem to cause problems. I found what the problem was by going to the directory and excuting this from the command line.

httpd -e info 

This gave me the error

Syntax error on line 156 of D:/.../Apache Software Foundation/Apache2.2/conf/httpd.conf:

#parent
{
    position : relative;
    height: 0;
    overflow: hidden;

}

img 
{
    height: auto!important;
    width: auto!important;
    min-height: 100%;
    min-width: 100%;
    position: absolute;

    bottom: -9999px;
    left: -9999px;
    right: -9999px;
    margin: auto;
}

I don't remember where I saw the centering method listed above, using negative top, right, bottom, left values. For me, this tehnique is the best, in most situations.

When I use the combination from above, the image behaves like a background-image with the following settings:

background-position: 50% 50%;
background-repeat: no-repeat;
background-size: cover;

More details about the first example can be found here:

iOS 5 has support for position:fixed.

I second zweiterlinde's suggestion to use python-graph. I've used it as the basis of a graph-based research project that I'm working on. The library is well written, stable, and has a good interface. The authors are also quick to respond to inquiries and reports.

Here's a solution to the general case that doesn't involve needing to know the length of the array ahead of time, using collect, or using udfs. Unfortunately this only works for spark version 2.1 and above, because it requires the posexplode function.

Suppose you had the following DataFrame:

df = spark.createDataFrame(
    [
        [1, 'A, B, C, D'], 
        [2, 'E, F, G'], 
        [3, 'H, I'], 
        [4, 'J']
    ]
    , ["num", "letters"]
)
df.show()
#+---+----------+
#|num|   letters|
#+---+----------+
#|  1|A, B, C, D|
#|  2|   E, F, G|
#|  3|      H, I|
#|  4|         J|
#+---+----------+

Split the letters column and then use posexplode to explode the resultant array along with the position in the array. Next use pyspark.sql.functions.expr to grab the element at index pos in this array.

import pyspark.sql.functions as f

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .show()
#+---+------------+---+---+
#|num|     letters|pos|val|
#+---+------------+---+---+
#|  1|[A, B, C, D]|  0|  A|
#|  1|[A, B, C, D]|  1|  B|
#|  1|[A, B, C, D]|  2|  C|
#|  1|[A, B, C, D]|  3|  D|
#|  2|   [E, F, G]|  0|  E|
#|  2|   [E, F, G]|  1|  F|
#|  2|   [E, F, G]|  2|  G|
#|  3|      [H, I]|  0|  H|
#|  3|      [H, I]|  1|  I|
#|  4|         [J]|  0|  J|
#+---+------------+---+---+

Now we create two new columns from this result. First one is the name of our new column, which will be a concatenation of letter and the index in the array. The second column will be the value at the corresponding index in the array. We get the latter by exploiting the functionality of pyspark.sql.functions.expr which allows us use column values as parameters.

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .show()
#+---+-------+---+
#|num|   name|val|
#+---+-------+---+
#|  1|letter0|  A|
#|  1|letter1|  B|
#|  1|letter2|  C|
#|  1|letter3|  D|
#|  2|letter0|  E|
#|  2|letter1|  F|
#|  2|letter2|  G|
#|  3|letter0|  H|
#|  3|letter1|  I|
#|  4|letter0|  J|
#+---+-------+---+

Now we can just groupBy the num and pivot the DataFrame. Putting that all together, we get:

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .groupBy("num").pivot("name").agg(f.first("val"))\
    .show()
#+---+-------+-------+-------+-------+
#|num|letter0|letter1|letter2|letter3|
#+---+-------+-------+-------+-------+
#|  1|      A|      B|      C|      D|
#|  3|      H|      I|   null|   null|
#|  2|      E|      F|      G|   null|
#|  4|      J|   null|   null|   null|
#+---+-------+-------+-------+-------+

As your query string is a literal, and assuming your dates are properly stored as DATE you should use date literals:

SELECT * FROM OrderArchive
WHERE OrderDate <= DATE '2015-12-31'

If you want to use TO_DATE (because, for example, your query value is not a literal), I suggest you to explicitly set the NLS_DATE_LANGUAGE parameter as you are using US abbreviated month names. That way, it won't break on some localized Oracle Installation:

SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014', 'DD MON YYYY',
                           'NLS_DATE_LANGUAGE = American');

$  perl -e 'local $/; $_ = <>; s/\n$//; print' a-text-file.txt

Or just do that:

var app = req.app

inside the Middleware you are using for these routes. Like that:

router.use( (req,res,next) => {
    app = req.app;
    next();
});

Add display: block; or display: inline-block; to your #User_Apps_Content .DLD_App a

Or like this

class Movie
{
  public string FilmName { get; set; }
  public string Genre { get; set; }
}

...

var listofGenres = new List<string> { "action", "comedy" };

var Movies = new List<Movie> {new Movie {Genre="action", FilmName="Film1"},
                new Movie {Genre="comedy", FilmName="Film2"},
                new Movie {Genre="comedy", FilmName="Film3"},
                new Movie {Genre="tragedy", FilmName="Film4"}};

var movies = Movies.Join(listofGenres, x => x.Genre, y => y, (x, y) => x).ToList();

Right click on the folder you want to download in, and open up tortoise-svn -> repo-browser.

Enter in the URL above in the next window.

right click on the trunk folder and choose either checkout (if you want to update from SVN later) or export (if you just want your own copy of that revision).

In (most) recent browsers, you can accept variable number of arguments with this syntax:

function my_log(...args) {
     // args is an Array
     console.log(args);
     // You can pass this array as parameters to another function
     console.log(...args);
}

Here's a small example:

function foo(x, ...args) {
  console.log(x, args, ...args, arguments);
}

foo('a', 'b', 'c', z='d')

=>

a
Array(3) [ "b", "c", "d" ]
b c d
Arguments
?    0: "a"
    ?1: "b"
    ?2: "c"
    ?3: "d"
    ?length: 4

Here's a solution if you want to check multiple conditions:

/* Handler to check multiple conditions
   */
  Handlebars.registerHelper('checkIf', function (v1,o1,v2,mainOperator,v3,o2,v4,options) {
      var operators = {
           '==': function(a, b){ return a==b},
           '===': function(a, b){ return a===b},
           '!=': function(a, b){ return a!=b},
           '!==': function(a, b){ return a!==b},
           '<': function(a, b){ return a<b},
           '<=': function(a, b){ return a<=b},
           '>': function(a, b){ return a>b},
           '>=': function(a, b){ return a>=b},
           '&&': function(a, b){ return a&&b},
           '||': function(a, b){ return a||b},
        }
      var a1 = operators[o1](v1,v2);
      var a2 = operators[o2](v3,v4);
      var isTrue = operators[mainOperator](a1, a2);
      return isTrue ? options.fn(this) : options.inverse(this);
  });

Usage:

/* if(list.length>0 && public){}*/

{{#checkIf list.length '>' 0 '&&' public '==' true}} <p>condition satisfied</p>{{/checkIf}}

Solution 1 - Using VirtualBox

As Muhammad Sahputra suggested in this post, it is possible to run Windows OS inside VirtualBox (using VBoxHeadless - without graphical interface) inside Docker container.

Also, a NAT setup inside the VM network configurations can do a port forwarding which gives you the ability to pass-through any traffic that comes to and from the Docker container. This eventually, in a wide perspective, allows you to run any Windows-based service on top of Linux machine.

Maybe this is not a typical use-case of a Docker container, but it definitely an interesting approach to the problem.

Solution 2 - Using Wine

For simple applications and maybe more complicated, you can try to use wine inside a docker container.

This docker hub page may help you to achieve your goal.

I hope that Docker will release a native solution soon, like they did with docker-machine on Windows several years ago.

A simple way to handle an exception on any particular method is:

using Microsoft.AspNetCore.Http;
...

public ActionResult MyAPIMethod()
{
    try
    {
       var myObject = ... something;

       return Json(myObject);
    }
    catch (Exception ex)
    {
        Log.Error($"Error: {ex.Message}");
        return StatusCode(StatusCodes.Status500InternalServerError);
    }         
}

Here's an example of a function that accepts a callback

const sqk = (x: number, callback: ((_: number) => number)): number => {
  // callback will receive a number and expected to return a number
  return callback (x * x);
}

// here our callback will receive a number
sqk(5, function(x) {
  console.log(x); // 25
  return x;       // we must return a number here
});

If you don't care about the return values of callbacks (most people don't know how to utilize them in any effective way), you can use void

const sqk = (x: number, callback: ((_: number) => void)): void => {
  // callback will receive a number, we don't care what it returns
  callback (x * x);
}

// here our callback will receive a number
sqk(5, function(x) {
  console.log(x); // 25
  // void
});

Note, the signature I used for the callback parameter ...

const sqk = (x: number, callback: ((_: number) => number)): number

I would say this is a TypeScript deficiency because we are expected to provide a name for the callback parameters. In this case I used _ because it's not usable inside the sqk function.

However, if you do this

// danger!! don't do this
const sqk = (x: number, callback: ((number) => number)): number

It's valid TypeScript, but it will interpreted as ...

// watch out! typescript will think it means ...
const sqk = (x: number, callback: ((number: any) => number)): number

Ie, TypeScript will think the parameter name is number and the implied type is any. This is obviously not what we intended, but alas, that is how TypeScript works.

So don't forget to provide the parameter names when typing your function parameters... stupid as it might seem.

You can register another directive on top of ng-click which amends the default behaviour of ng-click and stops the event propagation. This way you wouldn't have to add $event.stopPropagation by hand.

app.directive('ngClick', function() {
    return {
        restrict: 'A',
        compile: function($element, attr) {
            return function(scope, element, attr) {
                element.on('click', function(event) {
                    event.stopPropagation();
                });
            };
        }
    }
});

I had this issue and found that the problem was that I had not registered the JacksonFeature class:

// Create JAX-RS application.
final Application application = new ResourceConfig()
    ...
    .register(JacksonFeature.class);

Without doing this your application does not know how to convert the JSON to a java object.

The Diff Option only appears if the files are in a folder that is part of a Project.

Than you can actually compare files natively right in Sublime Text.

Navigate to the folder containing them through Open Folder... or in a project Select the two files (ie, by holding Ctrl on Windows or ? on macOS) you want to compare in the sidebar Right click and select the Diff files... option.

The correct answer for people using swift4 would be

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.title = "Your Text"
}

Here's an update to what Richard did that adds a "depth" indicator. The output is level-0, level-1, level-2, etc.

class UL_Class_Walker extends Walker_Nav_Menu {
  function start_lvl(&$output, $depth) {
    $indent = str_repeat("\t", $depth);
    $output .= "\n$indent<ul class=\"level-".$depth."\">\n";
  }

Microsoft Access and LibreOffice Base can open a spreadsheet as a source and run sql queries on it. That would be the easiest way to run all kinds of queries, and avoid the mess of running macros or writing code.

Excel also has autofilters and data sorting that will accomplish a lot of simple queries like your example. If you need help with those features, Google would be a better source for tutorials than me.

The only solution that worked for me was this command :

docker-compose build --no-cache

This will automatically pull fresh image from repo and won't use the cache version that is prebuild with any parameters you've been using before.

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

In Ultra Edit and Crimson (or Emerald) Editor you can enable/disable the column mode with Alt + C

You need to set line-height.

<div style="border: 1px solid red;">
<span style="font-size: 38px; vertical-align:middle; float:left; line-height: 38px">Hejsan</span>
<span style="font-size: 13px; vertical-align:middle; float:right; line-height: 38px">svejsan</span>
<div style="clear: both;"></div>

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

.inspect is what you're looking for, it's way easier IMO than .to_yaml!

user = User.new
user.name = "will"
user.email = "[email protected]"

user.inspect
#<name: "will", email: "[email protected]">

One more difference in C++, when you inherit a class from struct without any access specifier, it become public inheritance where as in case of class it's private inheritance.

you can keep your withdraw and deposit methods static if you want however you'd have to write it like the code below. sb = starting balance and eB = ending balance.

Account account = new Account(1122, 20000, 4.5);

    double sB = Account.withdraw(account.getBalance(), 2500);
    double eB = Account.deposit(sB, 3000);
    System.out.println("Balance is " + eB);
    System.out.println("Monthly interest is " + (account.getAnnualInterestRate()/12));
    account.setDateCreated(new Date());
    System.out.println("The account was created " + account.getDateCreated());

Add these lines to your build.gradle file:

android { 
  lintOptions { 
    abortOnError false 
  }
}

Then clean your project :D

max-width is definitely not well supported. If you're going to use it, use it in a media query in your style tag. ios, android, and windows phone default mail all support them. (gmail and outlook mobile don't)

Look at the starbucks example at the bottom

An array is a pointer. It points to the start of a sequence of "objects".

If we do this: ìnt arr[10];, then arr is a pointer to a memory location, from which ten integers follow. They are uninitialised, but the memory is allocated. It is exactly the same as doing int *arr = new int[10];.

The key checks for FAST REFRESH includes the following:

1) An Oracle materialized view log must be present for each base table.
2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition.
3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.

No 3 is easy to miss and worth highlighting here

I'm seeing this in a VS2017 environment. My build script calls VsDevCmd.bat first, and to solve this problem I set the VCTargetsPath environment variable after VsDevCmd and before calling MSBuild:

set VCTargetsPath=%VCIDEInstallDir%VCTargets

For Delete, you will need to do as per the following

axios.delete("/<your endpoint>", { data:<"payload object">})

It worked for me.

As already said, getElementsByClassName returns a HTMLCollection, which is defined as

[Exposed=Window]
interface HTMLCollection {
  readonly attribute unsigned long length;
  getter Element? item(unsigned long index);
  getter Element? namedItem(DOMString name);
};

Previously, some browsers returned a NodeList instead.

[Exposed=Window]
interface NodeList {
  getter Node? item(unsigned long index);
  readonly attribute unsigned long length;
  iterable<Node>;
};

The difference is important, because DOM4 now defines NodeLists as iterable.

According to Web IDL draft,

Objects implementing an interface that is declared to be iterable support being iterated over to obtain a sequence of values.

Note: In the ECMAScript language binding, an interface that is iterable will have “entries”, “forEach”, “keys”, “values” and @@iterator properties on its interface prototype object.

That means that, if you want to use forEach, you can use a DOM method which returns a NodeList, like querySelectorAll.

document.querySelectorAll(".myclass").forEach(function(element, index, array) {
  // do stuff
});

Note this is not widely supported yet. Also see forEach method of Node.childNodes?

You want to restrict to input fields that are of type text so use the selector input[type=text] rather than input (which will apply to all input fields (e.g. those of type submit as well)).

map is implemented from balanced binary search tree(usually a rb_tree), since all the member in balanced binary search tree is sorted so is map;

hash_map is implemented from hashtable.Since all the member in hashtable is unsorted so the members in hash_map(unordered_map) is not sorted.

hash_map is not a c++ standard library, but now it renamed to unordered_map(you can think of it renamed) and becomes c++ standard library since c++11 see this question Difference between hash_map and unordered_map? for more detail.

Below i will give some core interface from source code of how the two type map is implemented.

map:

The below code is just to show that, map is just a wrapper of an balanced binary search tree, almost all it's function is just invoke the balanced binary search tree function.

template <typename Key, typename Value, class Compare = std::less<Key>>
class map{
    // used for rb_tree to sort
    typedef Key    key_type;

    // rb_tree node value
    typedef std::pair<key_type, value_type> value_type;

    typedef Compare key_compare;

    // as to map, Key is used for sort, Value used for store value
    typedef rb_tree<key_type, value_type, key_compare> rep_type;

    // the only member value of map (it's  rb_tree)
    rep_type t;
};

// one construct function
template<typename InputIterator>
map(InputIterator first, InputIterator last):t(Compare()){
        // use rb_tree to insert value(just insert unique value)
        t.insert_unique(first, last);
}

// insert function, just use tb_tree insert_unique function
//and only insert unique value
//rb_tree insertion time is : log(n)+rebalance
// so map's  insertion time is also : log(n)+rebalance 
typedef typename rep_type::const_iterator iterator;
std::pair<iterator, bool> insert(const value_type& v){
    return t.insert_unique(v);
};

hash_map:

hash_map is implemented from hashtable whose structure is somewhat like this:

In the below code, i will give the main part of hashtable, and then gives hash_map.

// used for node list
template<typename T>
struct __hashtable_node{
    T val;
    __hashtable_node* next;
};

template<typename Key, typename Value, typename HashFun>
class hashtable{
    public:
        typedef size_t   size_type;
        typedef HashFun  hasher;
        typedef Value    value_type;
        typedef Key      key_type;
    public:
        typedef __hashtable_node<value_type> node;

        // member data is buckets array(node* array)
        std::vector<node*> buckets;
        size_type num_elements;

        public:
            // insert only unique value
            std::pair<iterator, bool> insert_unique(const value_type& obj);

};

Like map's only member is rb_tree, the hash_map's only member is hashtable. It's main code as below:

template<typename Key, typename Value, class HashFun = std::hash<Key>>
class hash_map{
    private:
        typedef hashtable<Key, Value, HashFun> ht;

        // member data is hash_table
        ht rep;

    public:
        // 100 buckets by default
        // it may not be 100(in this just for simplify)
        hash_map():rep(100){};

        // like the above map's insert function just invoke rb_tree unique function
        // hash_map, insert function just invoke hashtable's unique insert function
        std::pair<iterator, bool> insert(const Value& v){
                return t.insert_unique(v);
        };

};

Below image shows when a hash_map have 53 buckets, and insert some values, it's internal structure.

The below image shows some difference between map and hash_map(unordered_map), the image comes from How to choose between map and unordered_map?:

You can very easily use this to re-use the value of the variable in another function.

// Use this in source window.var1= oEvent.getSource().getBindingContext();

// Get value of var1 in destination var var2= window.var1;

Make a surrounding div-tag, and set for it display: grid in its style attribute.

<div style='display: grid; 
            text-align: center;
            background-color: antiquewhite'
>
  <table>
    <tr>
      <th>Month</th>
      <th>Savings</th>
    </tr>
    <tr>
      <td>January</td>
      <td>$100</td>
    </tr>
    <tr>
      <td>February</td>
      <td>$80</td>
    </tr>
  </table>
</div>

The text-align property is set only to show, that the text in the regular table cells are affected by it, even though it is set on the surrounding div. The same with the background-color but it is hard to say which element actually holds the background-color.

I had a table change and it created another entity with a number 1 at the end (such as MyEntity1 and a MyEntity) as confirmed by the edmx model browser. Something about the two entities together confused the processing.

Removal of the table and re-adding it fixed it.

Note that if TFS is hooked up, then do a check-in of the edmx in after the delete. Then and only then get the latest and re-add it in a definite two step process. Otherwise TFS gets confused with the delete and re-add of same named entity(ies) which seems to cause problems.

Use the form Initialize event, e.g.:

Private Sub UserForm_Initialize()
    TextBox1.Value = Format(Date, "mm/dd/yyyy")
End Sub

$? is the exit status of a command, such that you can daisy-chain a series of commands.

Example

command1 && command2 && command3

command2 will run if command1's $? yields a success (0) and command3 will execute if $? of command2 will yield a success

The only reliably way I know is to use VBScript to do the heavy work for you. There is no portable way of getting the current date in a usable format with a batch file alone. The following VBScript file

Wscript.Echo("set Year=" & DatePart("yyyy", Date))
Wscript.Echo("set Month=" & DatePart("m", Date))
Wscript.Echo("set Day=" & DatePart("d", Date))

and this batch snippet

for /f "delims=" %%x in ('cscript /nologo date.vbs') do %%x
echo %Year%-%Month%-%Day%

should work, though.

While you can get the current date in a batch file with either date /t or the %date% pseudo-variable, both follow the current locale in what they display. Which means you get the date in potentially any format and you have no way of parsing that.

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

This is a textbook case for a constructor function:

var myArray = [];

function myElement(id, value){
    this.id = id
    this.value = value
}

myArray[0] = new myElement(0,1)
myArray[1] = new myElement(2,3)
// or myArray.push(new myElement(1, 1))

As shown in the latest edit, the password is valid until 1970, which means it's currently invalid. This explains the error message which is the same as if the password was incorrect.

Reset the validity with:

ALTER USER postgres VALID UNTIL 'infinity';

In a recent question, another user had the same problem with user accounts and PG-9.2:

PostgreSQL - Password authentication fail after adding group roles

So apparently there is a way to unintentionally set a bogus password validity to the Unix epoch (1st Jan, 1970, the minimum possible value for the abstime type). Possibly, there's a bug in PG itself or in some client tool that would create this situation.

EDIT: it turns out to be a pgadmin bug. See https://dba.stackexchange.com/questions/36137/

Just enable parsing of the autoexec.bat in the registry, using these instructions.

:: works only on windows vista and earlier 
Run REGEDT32.EXE.
Modify the following value within HKEY_CURRENT_USER: 

Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ParseAutoexec 

1 = autoexec.bat is parsed
0 = autoexec.bat is not parsed

The domain name portion of a URL is not case sensitive since DNS ignores case: http://en.example.org/ and HTTP://EN.EXAMPLE.ORG/ both open the same page.

The path is used to specify and perhaps find the resource requested. It is case-sensitive, though it may be treated as case-insensitive by some servers, especially those based on Microsoft Windows.

If the server is case sensitive and http://en.example.org/wiki/URL is correct, then http://en.example.org/WIKI/URL or http://en.example.org/wiki/url will display an HTTP 404 error page, unless these URLs point to valid resources themselves.

You can turn on your PHP errors with error_reporting:

error_reporting(E_ALL);
ini_set('display_errors', 'on');

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

You should set display_errors = 1 in your php.ini file and restart the server.

In my case, I used react-render-html

First install the package by npm i --save react-render-html

then,

import renderHTML from 'react-render-html';

renderHTML("<a class='github' href='https://github.com'><b>GitHub</b></a>")

I'm using fileupload-jquery in haml. The original js is below:

      </td>_x000D_
    </tr>_x000D_
    {% } %}_x000D_
</script>

At first I used the :cdata to convert (from html2haml), it doesn't work properly (Delete button can't remove relevant component in callback).

<script id='template-download' type='text/x-tmpl'>_x000D_
      <![CDATA[_x000D_

          {% } %}_x000D_
      ]]>_x000D_
    </script>

So I use :plain filter:

%script#template-download{:type => "text/x-tmpl"}_x000D_
  :plain_x000D_
    {% for (var i=0, file; file=o.files[i]; i++) { %}_x000D_

    <input type="checkbox" name="delete" value="1">_x000D_
    </td>_x000D_
    </tr>_x000D_
    {% } %}

The converted result is exactly the same as the original.

So :plain filter in this senario fits my need.

:plain Does not parse the filtered text. This is useful for large blocks of text without HTML tags, when you don’t want lines starting with . or - to be parsed.

For more detail, please refer to haml.info

if the file containing that link tag is in the root dir of the project, then the correct path would be "css/styles.css"

If obj Is Nothing Then
    ' need to initialize obj: '
    Set obj = ...
Else
    ' obj already set / initialized. '
End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then
    ' obj already set / initialized. '
Else
    ' need to initialize obj: '
    Set obj = ...
End If

An API is the interface through which you access someone elses code or through which someone else's code accesses yours. In effect the public methods and properties.

You can access elements of parent window from within an iframe by using window.parent like this:

// using jquery    
window.parent.$("#element_id");

Which is the same as:

// pure javascript
window.parent.document.getElementById("element_id");

And if you have more than one nested iframes and you want to access the topmost iframe, then you can use window.top like this:

// using jquery
window.top.$("#element_id");

Which is the same as:

// pure javascript
window.top.document.getElementById("element_id");

EXEC sp_helpuser

or

SELECT * FROM sysusers

Both of these select all the users of the current database (not the server).

You may find your answer in the javadoc of Map#put(K, V) (which actually returns something):

public V put(K key,
             V value)

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for this key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Parameters:
key - key with which the specified value is to be associated.
value - value to be associated with the specified key.

Returns:
previous value associated with specified key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with the specified key, if the implementation supports null values.)

So if you don't assign the returned value when calling mymap.put("1", "a string"), it just becomes unreferenced and thus eligible for garbage collection.

Do this steps :-

Go to Run - Edit Configuration -> Application (on the left of the panel ) -> select the scala application that u want to run -> program argument

I almost always use curly-braces; however, in some cases where I'm writing tests, I do keyword packing/unpacking, and in these cases dict() is much more maintainable, as I don't need to change:

a=1,
b=2,

to:

'a': 1,
'b': 2,

It also helps in some circumstances where I think I might want to turn it into a namedtuple or class instance at a later time.

In the implementation itself, because of my obsession with optimisation, and when I don't see a particularly huge maintainability benefit, I'll always favour curly-braces.

In tests and the implementation, I would never use dict() if there is a chance that the keys added then, or in the future, would either:

• Not always be a string
• Not only contain digits, ASCII letters and underscores
• Start with an integer (dict(1foo=2) raises a SyntaxError)

That's because at the time of installation you have selected the default radio button to use "Git" with the "Git bash" only. If you would have chosen "Git and command line tool" than this would not be an issue.

• Solution#1: as you have already installed Git tool, now navigate to the desired folder and then right click and use "Git bash here" to run your same command and it will run properly.
• Solution#2: try installing again the Git-scm and select the proper choice.

It is the severity level of the error. The levels are from 11 - 20 which throw an error in SQL. The higher the level, the more severe the level and the transaction should be aborted.

You will get the syntax error when you do:

RAISERROR('Cannot Insert where salary > 1000').

Because you have not specified the correct parameters (severity level or state).

If you wish to issue a warning and not an exception, use levels 0 - 10.

From MSDN:

severity

Is the user-defined severity level associated with this message. When using msg_id to raise a user-defined message created using sp_addmessage, the severity specified on RAISERROR overrides the severity specified in sp_addmessage. Severity levels from 0 through 18 can be specified by any user. Severity levels from 19 through 25 can only be specified by members of the sysadmin fixed server role or users with ALTER TRACE permissions. For severity levels from 19 through 25, the WITH LOG option is required.

state

Is an integer from 0 through 255. Negative values or values larger than 255 generate an error. If the same user-defined error is raised at multiple locations, using a unique state number for each location can help find which section of code is raising the errors. For detailed description here

This process allows you to completely reproduce any Travis build job on your computer. Also, you can interrupt the process at any time and debug. Below is an example where I perfectly reproduce the results of job #191.1 on php-school/cli-menu .

Prerequisites

• You have public repo on GitHub
• You ran at least one build on Travis
• You have Docker set up on your computer

Set up the build environment

Reference: https://docs.travis-ci.com/user/common-build-problems/

1. Make up your own temporary build ID

   BUILDID="build-$RANDOM"
   

2. View the build log, open the show more button for WORKER INFORMATION and find the INSTANCE line, paste it in here and run (replace the tag after the colon with the newest available one):

   INSTANCE="travisci/ci-garnet:packer-1512502276-986baf0"
   

3. Run the headless server

   docker run --name $BUILDID -dit $INSTANCE /sbin/init
   

4. Run the attached client

   docker exec -it $BUILDID bash -l
   

Run the job

Now you are now inside your Travis environment. Run su - travis to begin.

This step is well defined but it is more tedious and manual. You will find every command that Travis runs in the environment. To do this, look for for everything in the right column which has a tag like 0.03s.

On the left side you will see the actual commands. Run those commands, in order.

Result

Now is a good time to run the history command. You can restart the process and replay those commands to run the same test against an updated code base.

• If your repo is private: ssh-keygen -t rsa -b 4096 -C "YOUR EMAIL REGISTERED IN GITHUB" then cat ~/.ssh/id_rsa.pub and click here to add a key
• FYI: you can git pull from inside docker to load commits from your dev box before you push them to GitHub
• If you want to change the commands Travis runs then it is YOUR responsibility to figure out how that translates back into a working .travis.yml.
• I don't know how to clean up the Docker environment, it looks complicated, maybe this leaks memory

I suspect that the problem lies in the fact that you are calling your state setter immediately inside the function component body, which forces React to re-invoke your function again, with the same props, which ends up calling the state setter again, which triggers React to call your function again.... and so on.

const SingInContainer = ({ message, variant}) => {
    const [open, setSnackBarState] = useState(false);
    const handleClose = (reason) => {
        if (reason === 'clickaway') {
          return;
        }
        setSnackBarState(false)

      };

    if (variant) {
        setSnackBarState(true); // HERE BE DRAGONS
    }
    return (
        <div>
        <SnackBar
            open={open}
            handleClose={handleClose}
            variant={variant}
            message={message}
            />
        <SignInForm/>
        </div>
    )
}

Instead, I recommend you just conditionally set the default value for the state property using a ternary, so you end up with:

const SingInContainer = ({ message, variant}) => {
    const [open, setSnackBarState] = useState(variant ? true : false); 
                                  // or useState(!!variant); 
                                  // or useState(Boolean(variant));
    const handleClose = (reason) => {
        if (reason === 'clickaway') {
          return;
        }
        setSnackBarState(false)

      };

    return (
        <div>
        <SnackBar
            open={open}
            handleClose={handleClose}
            variant={variant}
            message={message}
            />
        <SignInForm/>
        </div>
    )
}

Comprehensive Demo

See this CodeSandbox.io demo for a comprehensive demo of it working, plus the broken component you had, and you can toggle between the two.

If you have a checkbox in your html something like:

<input id="conducted" type = "checkbox" name="party" value="0">

and you want to add an EventListener to this checkbox using javascript, in your associated js file, you can do as follows:

checkbox = document.getElementById('conducted');

checkbox.addEventListener('change', e => {

    if(e.target.checked){
        //do something
    }

});

I haven't tested every single one of these answers but you don't need to use complicated functions to accomplish this. It's so much easier than that! My code below will work in any office VBA application (Word, Access, Excel, Outlook, etc.) and is very simple. Hope this helps:

''Dimension 2 Arrays
Dim InnerArray(1 To 3) As Variant ''The inner is for storing each column value of the current row
Dim OuterArray() As Variant ''The outer is for storing each row in
Dim i As Byte

    i = 1
    Do While i <= 5

        ''Enlarging our outer array to store a/another row
        ReDim Preserve OuterArray(1 To i)

        ''Loading the current row column data in
        InnerArray(1) = "My First Column in Row " & i
        InnerArray(2) = "My Second Column in Row " & i
        InnerArray(3) = "My Third Column in Row " & i

        ''Loading the entire row into our array
        OuterArray(i) = InnerArray

        i = i + 1
    Loop

    ''Example print out of the array to the Intermediate Window
    Debug.Print OuterArray(1)(1)
    Debug.Print OuterArray(1)(2)
    Debug.Print OuterArray(2)(1)
    Debug.Print OuterArray(2)(2)

Only add app:contentInsetStart="0dp" to the toolbar remove that left space.

So your Toolbar definition look like this

 <android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    app:contentInsetStart="0dp"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

and it look like this

Old question but none of the answers worked for me.

This article solved my problem by adding the following lines to web.config:

<system.webServer>
  <modules runAllManagedModulesForAllRequests="false">
    <remove name="WebDAVModule" />
  </modules>
</system.webServer>

The first answer doesn't reflect the current Container vs Presenter paradigm.

If you need to do something, like validate a password, you'd likely have a function that does it. You'd be passing that function to your reusable view as a prop.

Containers

So, the correct way to do it is to write a ValidatorContainer, which will have that function as a property, and wrap the form in it, passing the right props in to the child. When it comes to your view, your validator container wraps your view and the view consumes the containers logic.

Validation could be all done in the container's properties, but it you're using a 3rd party validator, or any simple validation service, you can use the service as a property of the container component and use it in the container's methods. I've done this for restful components and it works very well.

Providers

If there's a bit more configuration necessary, you can use a Provider/Consumer model. A provider is a high level component that wraps somewhere close to and underneath the top application object (the one you mount) and supplies a part of itself, or a property configured in the top layer, to the context API. I then set my container elements to consume the context.

The parent/child context relations don't have to be near each other, just the child has to be descended in some way. Redux stores and the React Router function in this way. I've used it to provide a root restful context for my rest containers (if I don't provide my own).

(note: the context API is marked experimental in the docs, but I don't think it is any more, considering what's using it).

//An example of a Provider component, takes a preconfigured restful.js_x000D_
//object and makes it available anywhere in the application_x000D_
export default class RestfulProvider extends React.Component {_x000D_
 constructor(props){_x000D_
  super(props);_x000D_
_x000D_
  if(!("restful" in props)){_x000D_
   throw Error("Restful service must be provided");_x000D_
  }_x000D_
 }_x000D_

A further way I haven't tried, but seen used, is to use middleware in conjunction with Redux. You define your service object outside the application, or at least, higher than the redux store. During store creation, you inject the service into the middleware and the middleware handles any actions that affect the service.

In this way, I could inject my restful.js object into the middleware and replace my container methods with independent actions. I'd still need a container component to provide the actions to the form view layer, but connect() and mapDispatchToProps have me covered there.

The new v4 react-router-redux uses this method to impact the state of the history, for example.

//Example middleware from react-router-redux_x000D_
//History is our service here and actions change it._x000D_
_x000D_
import { CALL_HISTORY_METHOD } from './actions'_x000D_
_x000D_
/**_x000D_
 * This middleware captures CALL_HISTORY_METHOD actions to redirect to the_x000D_
 * provided history object. This will prevent these actions from reaching your_x000D_
 * reducer or any middleware that comes after this one._x000D_
 */_x000D_
export default function routerMiddleware(history) {_x000D_
  return () => next => action => {_x000D_
    if (action.type !== CALL_HISTORY_METHOD) {_x000D_
      return next(action)_x000D_
    }_x000D_
_x000D_
    const { payload: { method, args } } = action_x000D_
    history[method](...args)_x000D_
  }_x000D_
}

Hercules is fantastic. It's a fully functioning tcp/udp client/server, amazing for debugging sockets. More details on the web site.

If $a is the array that's passed, $a[76][0]['id'] should give '76' and $a[76][1]['id'] should give '81', but I can't test as I don't have PHP installed on this machine.

Due to Oracle license restriction, there are no public repositories that provide ojdbc jar.

You need to download it and install in your local repository. Get jar from Oracle and install it in your local maven repository using

mvn install:install-file -Dfile={path/to/your/ojdbc.jar} -DgroupId=com.oracle 
-DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

If you are using ojdbc7, here is the link

May be the better way is

UIColor *color = [UIColor greenColor];
[self.myLabel setTextColor:color];

Thus we have colored text

As @idleberg mentions, on Mac OS, it is best to install rbenv to avoid permissions errors when using manually installed ruby.

Installation

$ brew update
$ brew install rbenv

Add the following in .bashrc file:

eval "$(rbenv init -)"

Now, we can look at the list of ruby versions available for install

$ rbenv install -l

Install version 2.3.8 for example

$ rbenv install 2.3.8

Now we can use this ruby version globally

$ rbenv global 2.3.8

Finally run

$ rbenv rehash

$ which ruby
/Users/myuser/.rbenv/shims/ruby
$ ruby -v
ruby 2.3.7p456 (2018-03-28 revision 63024) [x86_64-darwin17]

Go for it

Now install bundler

$ gem install bundler

All done!

Your int length = jsonObj.length(); should be int length = ja_data.length();

add the parameter -expandproperty after the select-object, it will return only data without header.

Depending on what you mean by "use them as Strings", you might not want to use an enum here. In most cases, the solution proposed by The Elite Gentleman will allow you to use them through their toString-methods, e.g. in System.out.println(STRING_ONE) or String s = "Hello "+STRING_TWO, but when you really need Strings (e.g. STRING_ONE.toLowerCase()), you might prefer defining them as constants:

public interface Strings{
  public static final String STRING_ONE = "ONE";
  public static final String STRING_TWO = "TWO";      
}

For folks interested in using JDOM, but afraid that hasn't been updated in a while (especially not leveraging Java generics), there is a fork called CoffeeDOM which exactly addresses these aspects and modernizes the JDOM API, read more here:

http://cdmckay.org/blog/2011/05/20/introducing-coffeedom-a-jdom-fork-for-java-5/

and download it from the project page at:

Try the following query:

;WITH CTE_DocTotal
 AS
 (
   SELECT SUM(Sale + VAT) AS DocTotal_1
   FROM PEDI_InvoiceDetail
   GROUP BY InvoiceNumber
 )

UPDATE CTE_DocTotal
SET DocTotal = CTE_DocTotal.DocTotal_1

Here you'll find your answer:

Using Git how do I find changes between local and remote

For the lazy:

1. Use "git log origin..HEAD"
2. Use "git fetch" followed by "git log HEAD..origin". You can cherry-pick individual commits using the listed commit ids.

The above assumes, of course, that "origin" is the name of your remote tracking branch (which it is if you've used clone with default options).

Go to http://getbootstrap.com/customize/ and toggle just what you want from the BS3 framework and then click "Compile and Download" and you'll get the CSS and JS that you chose.

Open up the CSS and remove all but the grid. They include some normalize stuff too. And you'll need to adjust all the styles on your site to box-sizing: border-box - http://www.w3schools.com/cssref/css3_pr_box-sizing.asp

In simple way, you can use the following code to clear all the text field, textarea, dropdown, radio button, checkbox in a form.

function reset(){
    $('input[type=text]').val('');  
    $('#textarea').val(''); 
    $('input[type=select]').val('');
    $('input[type=radio]').val('');
    $('input[type=checkbox]').val('');  
}

The answers over allow leading zeros in Ip address, and that it is not correct. For example ("123.045.067.089"should return false).

The correct way to do it like that.

 function isValidIP(ipaddress) {  
if (/^(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)\.(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)\.(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)\.(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)$/.test(ipaddress)) {  
  return (true)  
}   
return (false) } 

This function will not allow zero to lead IP addresses.

As of July 2020 the Chrome UI has changed once again and the logging level dropdown doesn't seem to do anything now.

Instead, there's a new pane to the left of the main console pane, which may have got unintentionally set to one of the restrictive logging levels:

Select the top category (messages) to reveal all the logging:

EDIT: EVEN THEN Chrome seems to add things to the Filter box, which again loses some logging, so you must CLEAR THE FILTER BOX TOO!

(Filter box is at the top of both my pics above, under "Network conditions"; you can see that it has some contents about "urlwebpack" which I didn't put there!)

Something like this?

foreach ($Offer as $key => $value) { 
  $offerArray[$key] = $value[4];
}

The classpath setting of the compiler plugin are two args. Changed it like this and it worked for me:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration>
  <compilerArgs>
     <arg>-cp</arg>
     <arg>${cp}:${basedir}/lib/bad.jar</arg>
  </compilerArgs>
</configuration>

I used the gmavenplus-plugin to read the path and create the property 'cp':

      <plugin>
    <!--
      Use Groovy to read classpath and store into
      file named value of property <cpfile>

      In second step use Groovy to read the contents of
      the file into a new property named <cp>

      In the compiler plugin this is used to create a
      valid classpath

Since it's a long time and people keep suggesting to use Scanner#nextLine(), there's another chance that Scanner can take spaces included in input.

Class Scanner

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.

You can use Scanner#useDelimiter() to change the delimiter of Scanner to another pattern such as a line feed or something else.

Scanner in = new Scanner(System.in);
in.useDelimiter("\n"); // use LF as the delimiter
String question;

System.out.println("Please input question:");
question = in.next();

// TODO do something with your input such as removing spaces...

if (question.equalsIgnoreCase("howdoyoulikeschool?") )
    /* it seems strings do not allow for spaces */
    System.out.println("CLOSED!!");
else
    System.out.println("Que?");

I use this,

input:-webkit-autofill { -webkit-box-shadow: 0 0 0px 1000px white inset !important; }
input:focus:-webkit-autofill { -webkit-box-shadow: 0 0 0px 1000px white inset !important; }
/* You can use color:#color to change the color */

Like the answers to many other questions in life, it depends. It depends on what your programming interests and goals are. If you want to program desktop applications, perhaps with a GUI, then C++ (and OOP) is probably a better way to go. If you're interested in hardware programming on something other than an x86 chipset, then C is often a better choice, usually for its speed. If you want to create a new media player or write a business app, I'd choose C++. If you want to do scientific simulations of galaxy collisions or fluid dynamics, behold the power of C.

PsPing from Sysinternals is also very good.

People say you can't and I understand you may be frustrated when asking a question and getting such an answer.

If you really want it to show in UTF-8 instead of US ASCII then you need to do it in two steps.

First:

iconv -f us-ascii -t utf-16 yourfile > youfileinutf16.*

Second:

iconv -f utf-16le -t utf-8 yourfileinutf16 > yourfileinutf8.*

Then if you do a file -i, you'll see the new character set is UTF-8.

You don't need the " to define a regular expression so just:

var regex = /(?!(?:[^<]+>|[^>]+<\/a>))\b(value)\b/is; // this is valid syntax

If value is a variable and you want a dynamic regular expression then you can't use this notation; use the alternative notation.

String.replace also accepts strings as input, so you can do "fox".replace("fox", "bear");

Alternative:

var regex = new RegExp("/(?!(?:[^<]+>|[^>]+<\/a>))\b(value)\b/", "is");
var regex = new RegExp("/(?!(?:[^<]+>|[^>]+<\/a>))\b(" + value + ")\b/", "is");
var regex = new RegExp("/(?!(?:[^<]+>|[^>]+<\/a>))\b(.*?)\b/", "is");

Keep in mind that if value contains regular expressions characters like (, [ and ? you will need to escape them.

Microsoft has also defined UINT_PTR and INT_PTR for integers that are the same size as a pointer.

Here is a list of Microsoft specific types - it's part of their driver reference, but I believe it's valid for general programming as well.

You can submit form by just clicking on checkbox by simple method in JavaScript. Inside form tag or Input attribute add following attribute:

    onchange="this.form.submit()"

Example:

<form>
      <div>
           <input type="checkbox">
      </div>
</form>

As long as I may need to access my PHP scripts with more than one method, what I do actually is:

if (in_array($_SERVER['REQUEST_METHOD'],array("GET","POST","DELETE"))) {
// do wathever I do 
}

The curly braces ({}) are used to import named bindings and the concept behind it is destructuring assignment

A simple demonstration of how import statement works with an example can be found in my own answer to a similar question at When do we use '{ }' in javascript imports?.

function closeWindow() {
    netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
    alert("This will close the window");
    window.open('','_self');
    window.close();
}

closeWindow();

If you are using PHP you might also want to take a look at minify which can minify and combine JavaScript files. The integration is pretty easy and can be done by defined groups of files or an easy query string. Minified files are also cached to reduce the server load and you can add expire headers through minify.

One shouldn't use set_yticklabels to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter), which is usually undesired. The easiest is to set the respective tick_params:

ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)

or

ax.tick_params(labelsize=8)

in case both axes shall have the same size.

Of course using the rcParams as in @tmdavison's answer is possible as well.

You need to check your relative path, based on depth of your modules from parent if module is just below parent then in module put relative path as: ../pom.xml

if its 2 level down then ../../pom.xml

Now you can use Template Literals:

var w = "the Word";_x000D_
var num1 = 2;_x000D_
var num2 = 3;_x000D_
_x000D_
var long_multiline_string = `This is very long_x000D_
multiline templete string. Putting somthing here:_x000D_
${w}_x000D_
I can even use expresion interpolation:_x000D_
Two add three = ${num1 + num2}_x000D_
or use Tagged template literals_x000D_
You need to enclose string with the back-tick (\` \`)`;_x000D_
_x000D_
console.log(long_multiline_string);

you can try this: 1. ensure you have added: compile 'com.android.support:design:25.3.1' (maybe you also should add compile 'com.android.support.constraint:constraint-layout:1.0.2') 2.

3.click the Infer Constraints, hope it can help you.

This is just namespacing. Look at the examples for reference - you need to either use the namespaced class or reference it absolutely, for example:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

//Load composer's autoloader
require 'vendor/autoload.php';

The following works well in a .php file.

<php? /*your block you want commented out*/ ?>

You can use %p in C

In C:

printf("%p",p)

In C++:

cout<<"Address of pointer p is: "<<p

To search for multiple matches in each file, we can sequence several Select-String calls:

Get-ChildItem C:\Logs |
  where { $_ | Select-String -Pattern 'VendorEnquiry' } |
  where { $_ | Select-String -Pattern 'Failed' } |
  ...

At each step, files that do not contain the current pattern will be filtered out, ensuring that the final list of files contains all of the search terms.

Rather than writing out each Select-String call manually, we can simplify this with a filter to match multiple patterns:

filter MultiSelect-String( [string[]]$Patterns ) {
  # Check the current item against all patterns.
  foreach( $Pattern in $Patterns ) {
    # If one of the patterns does not match, skip the item.
    $matched = @($_ | Select-String -Pattern $Pattern)
    if( -not $matched ) {
      return
    }
  }

  # If all patterns matched, pass the item through.
  $_
}

Get-ChildItem C:\Logs | MultiSelect-String 'VendorEnquiry','Failed',...

Now, to satisfy the "Logtime about 11:30 am" part of the example would require finding the log time corresponding to each failure entry. How to do this is highly dependent on the actual structure of the files, but testing for "about" is relatively simple:

function AboutTime( [DateTime]$time, [DateTime]$target, [TimeSpan]$epsilon ) {
  $time -le ($target + $epsilon) -and $time -ge ($target - $epsilon)
}

PS> $epsilon = [TimeSpan]::FromMinutes(5)
PS> $target = [DateTime]'11:30am'
PS> AboutTime '11:00am' $target $epsilon
False
PS> AboutTime '11:28am' $target $epsilon
True
PS> AboutTime '11:35am' $target $epsilon
True
