I've tried all the solutions above with version 4.2 of MAMP and none of them worked to me in El Capitan OS, so the only thing that worked was uninstalled MAMP with Clean My Mac and then install the older 3.5.2 version, that one worked right away.

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

If you don't have I just have .project and .classpath files in the directory, the only way that works (for me at least) with the latest version of Eclipse is:

1. Create a new Android project
   • File -> New -> Project... -> Android -> Android Application Project -> Next >
   • Fill in the values on this page and the following according to your application's needs
2. Get your existing code into the project you just created
   • Right click the src file in the Package Explorer
   • General -> File System -> Next >
   • Browse to your project, select the necessary files, hit Finish

After this, you should have a project with all your existing code as well as new .project and .classpath files.

This little application does the job for me. I could not find another CLI based client that would access my IIS based TLS/SSL secured ftp site: http://netwinsite.com/surgeftp/sslftp.htm

It is a very sensitive point to understand how to work System.out.print. If the first element is String then plus(+) operator works as String concate operator. If the first element is integer plus(+) operator works as mathematical operator.

public static void main(String args[]) {
    System.out.println("String" + 8 + 8); //String88
    System.out.println(8 + 8+ "String"); //16String
}

Check out a module I've written (you can use it in browser) which converts exif orientation to CSS transform: https://github.com/Sobesednik/exif2css

There is also this node program to generate JPEG fixtures with all orientations: https://github.com/Sobesednik/generate-exif-fixtures

Open your file, and then do something like...

for line in f:
    nlines += 1
    if (line.find(phrase) >= 0):
        print "Its here.", nlines

There are numerous ways of reading lines from files in Python, but the for line in f technique is more efficient than most.

Here's a trick: wrap it in sh -c!

screen sh -c './some-script 2>&1 | tee mylog.log'

Where 2>&1 redirects stderr to stdout so tee can catch and log error messages.

Try,

var newList = 
(
from x in empCollection
select new {Loc = x.empLoc, PL = x.empPL, Shift = x.empShift}
).Distinct();

Here is a trick if you want to calculate maximum(field, 0):

SELECT (ABS(field) + field)/2 FROM Table

returns 0 if field is negative, else, return field.

I typically Like to use the GridView.RowDataBound Event event for this.

protected void OrdersGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.ForeColor = System.Drawing.Color.Red;
    }
}

From the docs:

This tag can be used in two ways:

• {% extends "base.html" %} (with quotes) uses the literal value "base.html" as the name of the parent template to extend.
• {% extends variable %} uses the value of variable. If the variable evaluates to a string, Django will use that string as the name of the parent template. If the variable evaluates to a Template object, Django will use that object as the parent template.

So seems like you can't use a filter to manipulate the argument. In the calling view you have to either instantiate the ancestor template or create an string variable with the correct path and pass it with the context.

You do not need any client side code if doing this is ASP.NET. The example below is a boostrap input box with a search button with an fontawesome icon.

You will see that in place of using a regular < div > tag with a class of "input-group" I have used a asp:Panel. The DefaultButton property set to the id of my button, does the trick.

In example below, after typing something in the input textbox, you just hit enter and that will result in a submit.

<asp:Panel DefaultButton="btnblogsearch" runat="server" CssClass="input-group blogsearch">
<asp:TextBox ID="txtSearchWords" CssClass="form-control" runat="server" Width="100%" Placeholder="Search for..."></asp:TextBox>
<span class="input-group-btn">
    <asp:LinkButton ID="btnblogsearch" runat="server" CssClass="btn btn-default"><i class="fa fa-search"></i></asp:LinkButton>
</span></asp:Panel>

you can achieve this easily without writing Js. Just add an attribute called data-page-length={put your number here}. see example below, I used 100 for example

<table id="datatable-keytable" data-page-length='100' class="p-table table table-bordered" width="100%">

I thought the regular modulus operator would work for this in java, but it can't be hard to code. Just divide the numerator by the denominator, and take the integer portion of the result. Multiply that by the denominator, and subtract the result from the numerator.

x = n / d
xint = Integer portion of x
result = n - d * xint

Instead of using the dumpin.exe it is possible to call the link.exe with several options:

Example: link /dump /all myfile.lib

For detailed options see output of link /dump

In case of Visual Studio C++ Express installation, the link.exe is located here:

{root}\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\

The best way is to open the "Visual Studio Command Prompt" and then enter the lines above.

Some few things you must take care if you assign a reference to a new object to exports and /or modules.exports:

1. All properties/methods previously attached to the original exports or module.exports are of course lost because the exported object will now reference another new one

This one is obvious, but if you add an exported method at the beginning of an existing module, be sure the native exported object is not referencing another object at the end

exports.method1 = function () {}; // exposed to the original exported object
exports.method2 = function () {}; // exposed to the original exported object

module.exports.method3 = function () {}; // exposed with method1 & method2

var otherAPI = {
    // some properties and/or methods
}

exports = otherAPI; // replace the original API (works also with module.exports)

2. In case one of exports or module.exports reference a new value, they don't reference to the same object any more

exports = function AConstructor() {}; // override the original exported object
exports.method2 = function () {}; // exposed to the new exported object

// method added to the original exports object which not exposed any more
module.exports.method3 = function () {}; 

3. Tricky consequence. If you change the reference to both exports and module.exports, hard to say which API is exposed (it looks like module.exports wins)

// override the original exported object
module.exports = function AConstructor() {};

// try to override the original exported object
// but module.exports will be exposed instead
exports = function AnotherConstructor() {}; 

You can use String.replaceFirst with regex method like

    long phoneNum = 123456789L;
    System.out.println(String.valueOf(phoneNum).replaceFirst("(\\d{3})(\\d{3})(\\d+)", "($1)-$2-$3"));

From Errors and Exceptions # Handling exceptions - docs.python.org

The try ... except statement has an optional else clause, which, when present, must follow all except clauses. It is useful for code that must be executed if the try clause does not raise an exception. For example:

for arg in sys.argv[1:]:
    try:
        f = open(arg, 'r')
    except IOError:
        print 'cannot open', arg
    else:
        print arg, 'has', len(f.readlines()), 'lines'
        f.close()

The use of the else clause is better than adding additional code to the try clause because it avoids accidentally catching an exception that wasn’t raised by the code being protected by the try ... except statement.

With Java 8 Optional it can be done with:

    Optional<Obj> obj = dao.find();

    obj.map(obj.setAvailable(true)).orElseGet(() -> {
        logger.fatal("Object not available");
        return null;
    });

Been searching for answer but I came up with a dirty solution. Since my event fires twice, second action does nothing.

       $count = 1
       $action = { 
            if($count -eq 1){                  
                #DO SOMETHING
                $count = 2 
            }else{
                $count = 1
            }
        }  

You are doing it right; every time you need to add a row, simply so new TableRow(), etc. It might be easier for you to inflate the new row from XML though.

To set ANDROID_HOME environment on ubuntu 20.04 visit Ubuntu's snap store and install Android studio and then open

vim $HOME/.bashrc

And set the environment variables as follows:

export ANDROID_HOME=${HOME}/Android/Sdk
export PATH=${ANDROID_HOME}/tools:${PATH}
export PATH=${ANDROID_HOME}/emulator:${PATH}
export PATH=${ANDROID_HOME}/platform-tools:${PATH}

With recent versions of Android studio replace ANDROID_HOME with ANDROID_SDK_ROOT otherwise builds will complain that ANDROID_HOME is deprecated.

Just make a rule for each case:

<div id="homePage" ng-class="{ 'center': page.isSelected(1) , 'left': !page.isSelected(1)  }">

Or use the ternary operator:

<div id="homePage" ng-class="page.isSelected(1) ? 'center' : 'left'">

According to High-performance Mysql book:

The only difference between the BLOB and TEXT families is that BLOB types store binary data with no collation or character set, but TEXT types have a character set and collation.

Native JS solution:

 document.querySelector('input[name=gender][value=Female]').checked = true;

http://jsfiddle.net/jzQvH/75/

HTML:

<input type='radio' name='gender' value='Male'> Male
<input type='radio' name='gender' value='Female'>Female

I had the same error turns out the only thing i did wrong was to name my 'templates' folder,'template' without 's'. After changing that it worked fine,dont know why its a thing but it is.

The problem is here:

answer = newList.sort()

sort does not return the sorted list; rather, it sorts the list in place.

Use:

answer = sorted(newList)

I stumbled upon this question, looking for another answer.

I wanted to prevent all children from triggering the parent.

JavaScript:

document.getElementById("parent").addEventListener("click",  function (e) {
    if (this !== event.target) return;
    // Do something
});

jQuery:

$("#parent").click(function () {
    // Do something
}).children().on("click", function (e) {
    e.stopPropagation();
});

There are two common ways of doing that with built-in JSON serializers:

1. JavaScriptSerializer

   var serializer = new JavaScriptSerializer();
   return serializer.Serialize(TheList);
   

2. DataContractJsonSerializer

   var serializer = new DataContractJsonSerializer(TheList.GetType());
   using (var stream = new MemoryStream())
   {
       serializer.WriteObject(stream, TheList);
       using (var sr = new StreamReader(stream))
       {
           return sr.ReadToEnd();
       }
   }
   

   Note, that this option requires definition of a data contract for your class:

   [DataContract]
   public class MyObjectInJson
   {
      [DataMember]
      public long ObjectID {get;set;}
      [DataMember]
      public string ObjectInJson {get;set;}
   }
   

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

ERROR: must be owner of relation contact

PostgreSQL error messages are usually spot on. This one is spot on.

I see it hinted here and there, but you could also do a faster calculation first, like, compare the bounding boxes for overlap, and THEN do a radius-based overlap if that first test passes.

The addition/difference math is much faster for a bounding box than all the trig for the radius, and most times, the bounding box test will dismiss the possibility of a collision. But if you then re-test with trig, you're getting the accurate results that you're seeking.

Yes, it's two tests, but it will be faster overall.

If you are using archlinux or Ubuntu just type the commands below:

cd /opt/lampp/phpmyadmin

then

sudo gedit config.inc.php

Then when you access the file look for the scripts below,

//$cfg['Servers'][$i]['host'] ='localhost'

remove '//' so that it remains as shown below:

$cfg['Servers'][$i]['host'] ='localhost'

Then change the 'localhost' to '127.0.0.1' and the script should turn as shown below:

$cfg['Servers'][$i]['host'] ='127.0.0.1'

Get back to your browser and type http://127.0.0.1/phpmyadmin/

If it is still refusing

You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

so then get back to the same file config.inc.php you were editing and do as follows:

cd /opt/lampp/phpmyadmin

then

sudo gedit config.inc.php

search for the script below

$cfg['Servers'][$i]['password'] =''

Fill the password with your root password

$cfg['Servers'][$i]['password'] ='your_password'

And it should work.

Same solution, but just to remind you: You can define the shadow directly in the storyboard.

Ex:

Here is how to do it programatically:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {                
   getWindow().setNavigationBarColor(getResources().getColor(R.color.your_awesome_color));
}

Using Compat library:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setNavigationBarColor(ContextCompat.getColor(this, R.color.primary));
}

Here is how to do it with xml in the values-v21/style.xml folder:

<item name="android:navigationBarColor">@color/your_color</item>

1. first you can do with this style:

   mda="/usr/mda"
   if [ ! -L "${mda}" ]; then
     echo "=> File doesn't exist"
   fi
   

2. if you want to do it in more advanced style you can write it like below:

   #!/bin/bash
   mda="$1"
   if [ -e "$1" ]; then
       if [ ! -L "$1" ]
       then
           echo "you entry is not symlink"
       else
           echo "your entry is symlink"
       fi
   else
     echo "=> File doesn't exist"
   fi
   

the result of above is like:

root@linux:~# ./sym.sh /etc/passwd
you entry is not symlink
root@linux:~# ./sym.sh /usr/mda 
your entry is symlink
root@linux:~# ./sym.sh 
=> File doesn't exist

I wanted variable-width columns, and I didn't particularly care about the box characters. Also, I needed to print some extra information for each row.

So in case anyone else needs that, I'll save you few minutes:

    public interface ITextRow

            {
                owner = Owner;
                if (owner == null) throw new ArgumentException("Owner");
            }
            public String Output()

I had the same issue when uninstalled my Python27 and re-installed it.

I downloaded the sip-4.15.5 and PyQt-win-gpl-4.10.4 and installed/configured both of them. it still gives 'ImportError: No module named PyQt4.QtCore'. I tried to move the files/folders in Lib to make it looked 'have' but not working.

in fact, jut download the Windows 64 bit installer for a suitable Python version (my case) from http://www.riverbankcomputing.co.uk/software/pyqt/download and installed it, will do the job.

* March 2017 update *

The given link says, Binary installers for Windows are no longer provided.

See cgohlke's answer at, PyQt4 and 64-bit python.

1. Download the .whl file at http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4.
2. Use pip to install the downloaded .whl file.

Can be used as a one-liner too:

function repeat(str, len) {
    while (str.length < len) str += str.substr(0, len-str.length);
    return str;
}

You need to add overflow:auto to your parent div for it to encompass the inner floated div:

<div style="margin:0 auto;width: 960px; min-height: 100px; background-color:orange;overflow:auto">
    <div style="width:500px; height:200px; background-color:black; float:right">
    </div>
</div>

While @Eli is quite correct that there usually isn't much of a need to do it, it is possible. savefig takes a bbox_inches argument that can be used to selectively save only a portion of a figure to an image.

Here's a quick example:

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = ax2.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

# Pad the saved area by 10% in the x-direction and 20% in the y-direction
fig.savefig('ax2_figure_expanded.png', bbox_inches=extent.expanded(1.1, 1.2))

The full figure:

Area inside the second subplot:

Area around the second subplot padded by 10% in the x-direction and 20% in the y-direction:

You can create a sub-interface for that special case:

interface Command extends Action<Void, Void> {
  default Void execute(Void v) {
    execute();
    return null;
  }
  void execute();
}

It uses a default method to override the inherited parameterized method Void execute(Void), delegating the call to the simpler method void execute().

The result is that it's much simpler to use:

Command c = () -> System.out.println("Do nothing!");

You can make use of Floyd's cycle-finding algorithm, also known as tortoise and hare algorithm.

The idea is to have two references to the list and move them at different speeds. Move one forward by 1 node and the other by 2 nodes.

• If the linked list has a loop they will definitely meet.
• Else either of the two references(or their next) will become null.

Java function implementing the algorithm:

boolean hasLoop(Node first) {

    if(first == null) // list does not exist..so no loop either
        return false;

    Node slow, fast; // create two references.

    slow = fast = first; // make both refer to the start of the list

    while(true) {

        slow = slow.next;          // 1 hop

        if(fast.next != null)
            fast = fast.next.next; // 2 hops
        else
            return false;          // next node null => no loop

        if(slow == null || fast == null) // if either hits null..no loop
            return false;

        if(slow == fast) // if the two ever meet...we must have a loop
            return true;
    }
}

Problem 1 : Different applications use different scales for HSV. For example gimp uses H = 0-360, S = 0-100 and V = 0-100. But OpenCV uses H: 0-179, S: 0-255, V: 0-255. Here i got a hue value of 22 in gimp. So I took half of it, 11, and defined range for that. ie (5,50,50) - (15,255,255).

Problem 2: And also, OpenCV uses BGR format, not RGB. So change your code which converts RGB to HSV as follows:

cv.CvtColor(frame, frameHSV, cv.CV_BGR2HSV)

Now run it. I got an output as follows:

Hope that is what you wanted. There are some false detections, but they are small, so you can choose biggest contour which is your lid.

EDIT:

As Karl Philip told in his comment, it would be good to add new code. But there is change of only a single line. So, I would like to add the same code implemented in new cv2 module, so users can compare the easiness and flexibility of new cv2 module.

import cv2
import numpy as np

img = cv2.imread('sof.jpg')

ORANGE_MIN = np.array([5, 50, 50],np.uint8)
ORANGE_MAX = np.array([15, 255, 255],np.uint8)

hsv_img = cv2.cvtColor(img,cv2.COLOR_BGR2HSV)

frame_threshed = cv2.inRange(hsv_img, ORANGE_MIN, ORANGE_MAX)
cv2.imwrite('output2.jpg', frame_threshed)

It gives the same result as above. But code is much more simpler.

I don't think that there are any neat tricks you can do storing this as you can do for example with an MD5 hash.

I think your best bet is to store it as a CHAR(60) as it is always 60 chars long

You will need two things. The first is @media screen to activate the specific code at a certain screen size, used for responsive design. The second is the use of the visibility: hidden attribute. Once the browser/screen reaches 600pixels then #title_message will become hidden.

@media screen and (max-width: 600px) {
  #title_message {
    visibility: hidden;
    clear: both;
    float: left;
    margin: 10px auto 5px 20px;
    width: 28%;
    display: none;
  }
}

EDIT: if you are using another CSS for mobile then just add the visibility: hidden; to #title_message. Hope this helps you!

Use the setting log4j.appender.FILE.RollingPolicy.FileNamePattern, e.g. log4j.appender.FILE.RollingPolicy.FileNamePattern=F:/logs/filename.log.%d{dd}.gz for keeping logs one month before rolling over.

I didn't wait for one month to check but I tried with mm (i.e. minutes) and confirmed it overwrites, so I am assuming it will work for all patterns.

You can also install Git Credential Manager for Windows to save Git passwords in Windows credentials manager instead of _netrc. This is a more secure way to store passwords.

Instructions telling sudo pip install are inherently wrong.

If there is any tutorial out there which says you should do sudo pip then please file a bug against this package. The author is dis-educating Python community, as time has proven sudo pip to be a broken practice.

OSX El Capitan introduced a mechanisms to prevent damaging the operating system files. /System/Library/Frameworks/Python.framework/Versions/2.7/share is one of the protected locations. A normal user has no reason to put or write any files there. This is because the operating system itself relies on these files and sudo pip, with all force given from the above, would unconditionally overwrite them. Usually bad things would not happen, but the chances are there. Apple wants to protect their OS users to accidentally bricking their installation.

Instead, you need to install a Python package, like IPython, locally to the home folder of your user. The easiest way is to create a virtual environment, activate it and then run pip in the virtual environment.

Example:

cd ~  # Go to home directory
virtualenv my-venv
source my-venv/bin/activate
pip install IPython

More info

• Official Python package installation tutorial.

• How to create virtual environments.

Alternatively, one should be able to do pip install --user. But again, no sudo needed and you need to manually set up PATH environment variable.

The return false prevents the default behavior. but the return false breaks the bubbling of additional click events. This means if there are any other click bindings after this function gets called, those others do not Consider.

 <button id="btnSubmit" type="button">PostData</button>
 <Script> $("#btnSubmit").click(function(){
   // do stuff
   return false;
}); </Script>

Or simply you can put like this

 <button type="submit" onclick="return false"> PostData</button>

The solution is quite simple.

In your php.ini, just uncomment the line extension=php_gd2.dll (or .so extension for unix systems.)

Hope it helps.

Try:

EditText edt = (EditText) findViewById(R.id.YourEditText);
RelativeLayout.LayoutParams lp =
    new RelativeLayout.LayoutParams
    (
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
    );
lp.setMargins(25, 0, 0, 0); // move 25 px to right (increase left margin)
edt.setLayoutParams(lp); // lp.setMargins(left, top, right, bottom);

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

For a simple two- (or one) liner this code can be:

checkboxes = document.getElementsByName("NameOfCheckboxes");
selectedCboxes = Array.prototype.slice.call(checkboxes).filter(ch => ch.checked==true);

Here the Array.prototype.slice.call() part converts the object NodeList of all the checkboxes holding that name ("NameOfCheckboxes") into a new array, on which you then use the filter method. You can then also, for example, extract the values of the checkboxes by adding a .map(ch => ch.value) on the end of line 2. The => is javascript's arrow function notation.

1. Get UI Thread Handler instance and use handler.sendMessage();
2. Call post() method handler.post();
3. runOnUiThread()
4. view.post()

You just need to specify a minimum date - setting it to 0 means that the minimum date is 0 days from today i.e. today. You could pass the string '0d' instead (the default unit is days).

$(function () {
    $('#date').datepicker({ minDate: 0 });
});

Create Interface named with PreferenceManager:

// Interface to save values in shared preferences and also for retrieve values from shared preferences
public interface PreferenceManager {

    SharedPreferences getPreferences();
    Editor editPreferences();

    void setString(String key, String value);
    String getString(String key);

    void setBoolean(String key, boolean value);
    boolean getBoolean(String key);

    void setInteger(String key, int value);
    int getInteger(String key);

    void setFloat(String key, float value);
    float getFloat(String key);

}

How to use with Activity / Fragment:

public class HomeActivity extends AppCompatActivity implements PreferenceManager{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout_activity_home);
    }

    @Override
    public SharedPreferences getPreferences(){
        return getSharedPreferences("SP_TITLE", Context.MODE_PRIVATE);
    }

    @Override
    public SharedPreferences.Editor editPreferences(){
        return getPreferences().edit();
    }

    @Override
    public void setString(String key, String value) {
        editPreferences().putString(key, value).commit();
    }

    @Override
    public String getString(String key) {
        return getPreferences().getString(key, "");
    }

    @Override
    public void setBoolean(String key, boolean value) {
        editPreferences().putBoolean(key, value).commit();
    }

    @Override
    public boolean getBoolean(String key) {
        return  getPreferences().getBoolean(key, false);
    }

    @Override
    public void setInteger(String key, int value) {
        editPreferences().putInt(key, value).commit();
    }

    @Override
    public int getInteger(String key) {
        return getPreferences().getInt(key, 0);
    }

    @Override
    public void setFloat(String key, float value) {
        editPreferences().putFloat(key, value).commit();
    }

    @Override
    public float getFloat(String key) {
        return getPreferences().getFloat(key, 0);
    }
}

Note: Replace your key of SharedPreference with SP_TITLE.

Examples:

Store string in shareperence:

setString("my_key", "my_value");

Get string from shareperence:

String strValue = getString("my_key");

Hope this will help you.

The only standard mandated implementation dependent way is to use the system() function from stdlib.h.

Also if you know how to make user become the super-user that would be nice also.

Do you want the script to run as super-user or do you want to elevate the privileges of the C executable? The former can be done with sudo but there are a few things you need to know before you can go off using sudo.

Yes. you can use SimpleDateFormat like this.

SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));

Output OldDate-->2011-03-10T11:54:30.207Z NewDate-->10-Mar-2011 11:54:30.207

Try string.Remove();

string str = "1,5,12,34,";

Use these codes and enjoy it.

Public Function GetDirectoryName(ByVal source As String) As String()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection

Dim source_file() As String
Dim i As Integer        

queue.Add fso.GetFolder(source) 'obviously replace

Do While queue.Count > 0
    Set oFolder = queue(1)
    queue.Remove 1 'dequeue
    '...insert any folder processing code here...
    For Each oSubfolder In oFolder.SubFolders
        queue.Add oSubfolder 'enqueue
    Next oSubfolder
    For Each oFile In oFolder.Files
        '...insert any file processing code here...
        'Debug.Print oFile
        i = i + 1
        ReDim Preserve source_file(i)
        source_file(i) = oFile
    Next oFile
Loop
GetDirectoryName = source_file
End Function

And here you can call function:

Sub test()
Dim s
For Each s In GetDirectoryName("C:\New folder")
Debug.Print s
Next
End Sub

The following worked out for me like a charm:

1. I checked the warnings that showed up when I built the Project
2. Some of them mentioned something about assembly version conflict. Visual studio suggested that I clicked on the warning and hit Enter. A popup window offered to automatically fix the issue and so I did.
3. Problem solved!

    Dim rCell As Range
    Dim rRng As Range

    Set rRng = Sheet1.Range("A1:A6")

    For Each rCell In rRng.Cells

    Next rCell

End Sub

Another possible solution which I think is more semantically correct is to change the floated inner elements to be 'display: inline'. This example and what I was working on when I came across this page both use floated divs in much exactly the same way that a span would be used. Instead of using divs, switch to span, or if you are using another element which is by default 'display: block' instead of 'display: inline' then change it to be 'display: inline'. I believe this is the 100% semantically correct solution.

Solution 1, floating the parent, is essentially to change the entire document to be floated.

Solution 2, setting an explicit height, is like drawing a box and saying I want to put a picture here, i.e. use this if you are doing an img tag.

Solution 3, adding a spacer to clear float, is like adding an extra line below your content and will mess with surrounding elements too. If you use this approach you probably want to set the div to be height: 0px.

Solution 4, overflow: auto, is acknowledging that you don't know how to lay out the document and you are admitting that you don't know what to do.

I accidentally created a migration with a bad name (command: php artisan migrate:make). I did not run (php artisan migrate) the migration, so I decided to remove it. My steps:

1. Manually delete the migration file under app/database/migrations/my_migration_file_name.php
2. Reset the composer autoload files: composer dump-autoload
3. Relax

If you did run the migration (php artisan migrate), you may do this:

a) Run migrate:rollback - it is the right way to undo the last migration (Thnx @Jakobud)

b) If migrate:rollback does not work, do it manually (I remember bugs with migrate:rollback in previous versions):

1. Manually delete the migration file under app/database/migrations/my_migration_file_name.php
2. Reset the composer autoload files: composer dump-autoload
3. Modify your database: Remove the last entry from the migrations table

Have you tried

document.getElementById('body').style.display = "none";

instead of

document.getElementById('body').style.display = "hidden";?

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

$sqlquery = "SELECT field1, field2 FROM table WHERE columnA <> 'x' AND columbB <> 'y'";

I'd suggest using the diamond operator (<>) in favor of != as the first one is valid SQL and the second one is a MySQL addition.

After adding the JDK repo, before Installing you might want to run an update first so the repo can be added run apt update

If you want to use justify align in Jupyter Notebook use the following syntax:

<p style='text-align: justify;'> Your Text </p>

For right alignment:

<p style='text-align: right;'> Your Text </p>

In bootstrap 4 it is much easier to have a border on the fieldset that blends with the legend. You don't need custom css to achieve it, it can be done like this:

<fieldset class="border p-2">
   <legend  class="w-auto">Your Legend</legend>
</fieldset>

which looks like this:

$array = array('foo' => 'bar', 33 => 'bin', 'lorem' => 'ipsum');
$array = array_values($array);
echo $array[0]; //bar
echo $array[1]; //bin
echo $array[2]; //ipsum

A quick & concise difference overview :

attr_accessor is an easy way to create read and write accessors in your class. It is used when you do not have a column in your database, but still want to show a field in your forms. This field is a “virtual attribute” in a Rails model.

virtual attribute – an attribute not corresponding to a column in the database.

attr_accessible is used to identify attributes that are accessible by your controller methods makes a property available for mass-assignment.. It will only allow access to the attributes that you specify, denying the rest.

If your function have two vector variables and must compute itself on each value of them (as mentioned by @Ari B. Friedman) you can use mapply as follows:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
mapply(mult_one,vars1,vars2)

which gives you:

> mapply(mult_one,vars1,vars2)
[1] 10 40 90

There are few mistakes you are doing:

1. You need to add proper object in the array in addRow method
2. You can use splice method to remove an element from an array at particular index.
3. You need to pass the current row as prop to my-item component, where this can be modified.

You can see working code here.

addRow(){
   this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
   this. itemList.splice(index, 1)
}

I agree with @Marlon. When you compile your C# project with the Release configuration, you will find into the "bin/Release" folder of your project the executable of your application. This SHOULD work for a simple application.

But, if your application have any dependencies on some external dll, I suggest you to create a SetupProject with VisualStudio. Doing so, the project wizard will find all dependencies of your application and add them (the librairies) to the installation folder. Finally, all you will have to do is run the setup on the users computer and install your software.

You could do it like this:

var mydiv = document.getElementById("mydiv");
var content = "<script>alert(\"hi\");<\/script>";

mydiv.innerHTML = content;
var scripts = mydiv.getElementsByTagName("script");
for (var i = 0; i < scripts.length; i++) {
    eval(scripts[i].innerText);
}

A funny way to remove all spaces from a variable is to use printf:

$ myvar='a cool variable    with   lots of   spaces in it'
$ printf -v myvar '%s' $myvar
$ echo "$myvar"
acoolvariablewithlotsofspacesinit

It turns out it's slightly more efficient than myvar="${myvar// /}", but not safe regarding globs (*) that can appear in the string. So don't use it in production code.

If you really really want to use this method and are really worried about the globbing thing (and you really should), you can use set -f (which disables globbing altogether):

$ ls
file1  file2
$ myvar='  a cool variable with spaces  and  oh! no! there is  a  glob  *  in it'
$ echo "$myvar"
  a cool variable with spaces  and  oh! no! there is  a  glob  *  in it
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglobfile1file2init
$ # See the trouble? Let's fix it with set -f:
$ set -f
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglob*init
$ # Since we like globbing, we unset the f option:
$ set +f

I posted this answer just because it's funny, not to use it in practice.

The following codes can be used:

@app.route('/api/add_message/<uuid>', methods=['GET', 'POST'])
def add_message(uuid):
  content = request.json['text']
  print content
  return uuid

Here is a screenshot of me getting the json data:

You can see that what is returned is a dictionary type of data.

  width: 50%;_x000D_
  /* whatever width you want */_x000D_
  display: inline-block;_x000D_
  position: relative;_x000D_
}_x000D_
.wrapper:after {_x000D_
  padding-top: 56.25%;_x000D_
  /* 16:9 ratio */_x000D_
  display: block;_x000D_
  content: '';_x000D_
}_x000D_
.main {_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  bottom: 0;_x000D_
  right: 0;_x000D_
  left: 0;_x000D_
  /* fill parent */_x000D_
  background-color: deepskyblue;_x000D_
  /* let's see it! */_x000D_
  color: white;_x000D_
}

<div class="wrapper">_x000D_
  <div class="main">_x000D_
    This is your div with the specified aspect ratio._x000D_
  </div>_x000D_
</div>

Hope this helps...

class SomeClass{
  //Code snippet here...
}

Code snippet 1: Absolutely OK - all checked exceptions handled

static void m1(){
        try{
            throw new Exception();
        } catch(Exception e){
            System.out.println(e);
        }
}
static{
        m1();
}

Code snippet 2: Won't compile - unreported checked exception

static void m1() throws Exception{
        throw new Exception();
}
static{
        m1();
}

Code snippet 3: OK (see code snippet 1)

static void m1() throws Exception{
        throw new Exception();
}
static{
        try{m1();}
        catch(Exception e){
            System.out.println(e);
            //or whatever
        }
}

Code snippet 4: Compilation error, initilalizer must be able to complete normally

static{
        throw new RuntimeException();
}

Basically it boils down to this:

1. Inside the static block, every checked exception MUST have a handler.
2. If a RuntimeException were to occur, it would be wrapped in ExceptionInInitializerError and then the latter would be thrown.

This makes sense as A CLASS SHOULD BE ABLE TO COMPLETE INITIALIZATION NORMALLY. If this happens to be a problem, this should be categorized as an Error (from which recovery is usually difficult or impossible) rather than an Exception (which is usually recoverable)...

Building on couple of the above answers, you could do this:

<button onclick="location.href='@Url.Action("ActionName", "ControllerName")'" />

I try my darned best to write exception-safe code, yes.

That means I take care to keep an eye on which lines can throw. Not everyone can, and it is critically important to keep that in mind. The key is really to think about, and design your code to satisfy, the exception guarantees defined in the standard.

Can this operation be written to provide the strong exception guarantee? Do I have to settle for the basic one? Which lines may throw exceptions, and how can I ensure that if they do, they don't corrupt the object?

Instead of using the command line to do

copy /b 1.mp3+2.mp3 3.mp3

you could instead use "The Rename" to rename all the MP3 fragments into a series of names that are in order based on some kind of counter. Then you could just use the same command line format but change it a little to:

copy /b *.mp3 output_name.mp3

That is assuming you ripped all of these fragment MP3's at the same time and they have the same audio settings. Worked great for me when I was converting an Audio book I had in .aa to a single .mp3. I had to burn all the .aa files to 9 CD's then rip all 9 CD's and then I was left with about 90 mp3's. Really a pain in the a55.

The annotation mappedBy ideally should always be used in the Parent side (Company class) of the bi directional relationship, in this case it should be in Company class pointing to the member variable 'company' of the Child class (Branch class)

The annotation @JoinColumn is used to specify a mapped column for joining an entity association, this annotation can be used in any class (Parent or Child) but it should ideally be used only in one side (either in parent class or in Child class not in both) here in this case i used it in the Child side (Branch class) of the bi directional relationship indicating the foreign key in the Branch class.

below is the working example :

parent class , Company

@Entity
public class Company {


    private int companyId;
    private String companyName;
    private List<Branch> branches;

    @Id
    @GeneratedValue
    @Column(name="COMPANY_ID")
    public int getCompanyId() {
        return companyId;
    }

    public void setCompanyId(int companyId) {
        this.companyId = companyId;
    }

    @Column(name="COMPANY_NAME")
    public String getCompanyName() {
        return companyName;
    }

    public void setCompanyName(String companyName) {
        this.companyName = companyName;
    }

    @OneToMany(fetch=FetchType.LAZY,cascade=CascadeType.ALL,mappedBy="company")
    public List<Branch> getBranches() {
        return branches;
    }

    public void setBranches(List<Branch> branches) {
        this.branches = branches;
    }


}

child class, Branch

@Entity
public class Branch {

    private int branchId;
    private String branchName;
    private Company company;

    @Id
    @GeneratedValue
    @Column(name="BRANCH_ID")
    public int getBranchId() {
        return branchId;
    }

    public void setBranchId(int branchId) {
        this.branchId = branchId;
    }

    @Column(name="BRANCH_NAME")
    public String getBranchName() {
        return branchName;
    }

    public void setBranchName(String branchName) {
        this.branchName = branchName;
    }

    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name="COMPANY_ID")
    public Company getCompany() {
        return company;
    }

    public void setCompany(Company company) {
        this.company = company;
    }


}

If you have multiple elements with same id or same name, just assign same class to those multiple elements and access them by index & perform your required operation.

  <div>
        <span id="a" class="demo">1</span>
        <span id="a" class="demo">2</span>
        <span>3</span>
    </div>

JQ:

$($(".demo")[0]).val("First span");
$($(".demo")[1]).val("Second span");

Instead of strtotime you should use DateTime with PHP. You can also regard the timezone this way:

$dt = DateTime::createFromFormat('Y-m-d H:i:s', $mysqltime, new DateTimeZone('Europe/Berlin'));
$unix_timestamp = $dt->getTimestamp();

$mysqltime is of type MySQL Datetime, e. g. 2018-02-26 07:53:00.

read the following article http://mycodelines.wordpress.com/2009/09/01/in-which-scenario-we-use-abstract-classes-and-interfaces/

Abstract Classes

–> When you have a requirement where your base class should provide default implementation of certain methods whereas other methods should be open to being overridden by child classes use abstract classes.

For e.g. again take the example of the Vehicle class above. If we want all classes deriving from Vehicle to implement the Drive() method in a fixed way whereas the other methods can be overridden by child classes. In such a scenario we implement the Vehicle class as an abstract class with an implementation of Drive while leave the other methods / properties as abstract so they could be overridden by child classes.

–> The purpose of an abstract class is to provide a common definition of a base class that multiple derived classes can share.

For example a class library may define an abstract class that is used as a parameter to many of its functions and require programmers using that library to provide their own implementation of the class by creating a derived class.

Use an abstract class

When creating a class library which will be widely distributed or reused—especially to clients, use an abstract class in preference to an interface; because, it simplifies versioning. This is the practice used by the Microsoft team which developed the Base Class Library. ( COM was designed around interfaces.) Use an abstract class to define a common base class for a family of types. Use an abstract class to provide default behavior. Subclass only a base class in a hierarchy to which the class logically belongs.

You can simply add show.legend=FALSE to geom to suppress the corresponding legend

Another point to take in consideration is that the new UI for Service Interface will give you much more flexibility on how you want to create your proxy class. For example, it will allow you to map data contracts to existing dlls, if they match (actually this is the default behaviour).

Here is a good start maybe

Double.ToString()

Have a look in the examples for a number of different formating options Double.ToString(string)

In Swift 3.0

Dispatch queues

  DispatchQueue(label: "test").async {
        //long running Background Task
        for obj in 0...1000 {
            print("async \(obj)")
        }

        // UI update in main queue
        DispatchQueue.main.async(execute: { 
            print("UI update on main queue")
        })

    }

    DispatchQueue(label: "m").sync {
        //long running Background Task
        for obj in 0...1000 {
            print("sync \(obj)")
        }

        // UI update in main queue
        DispatchQueue.main.sync(execute: {
            print("UI update on main queue")
        })
    }

Dispatch after 5 seconds

    DispatchQueue.main.after(when: DispatchTime.now() + 5) {
        print("Dispatch after 5 sec")
    }

There's a Babel plugin that allows you to write conditional statements inside JSX without needing to escape them with JavaScript or write a wrapper class. It's called JSX Control Statements:

<View style={styles.container}>
  <If condition={ this.state == 'news' }>
    <Text>data</Text>
  </If>
</View>

It takes a bit of setting up depending on your Babel configuration, but you don't have to import anything and it has all the advantages of conditional rendering without leaving JSX which leaves your code looking very clean.

I asked the same question of the lodash maintainers a while back and they replied by mentioning the != operator can be used here:

if(newVal != null) {
  // newVal is defined
}

This uses JavaScript's type coercion to check the value for undefined or null.

If you are using JSHint to lint your code, add the following comment blocks to tell it that you know what you are doing - most of the time != is considered bad.

/* jshint -W116 */ 
if(newVal != null) {
/* jshint +W116 */
  // newVal is defined
}

You could create an installer for you EXE file by:
1. Press WinKey + R
2. Type "iexpress" (without quotes) into the run window
3. Complete the wizard for creating the installation program.
4. Distribute the completed EXE.

I don't know if this is new functionality, but this will plot on separate figures:

df.plot(y='korisnika')
df.plot(y='osiguranika')

while this will plot on the same figure: (just like the code in the op)

df.plot(y=['korisnika','osiguranika'])

I found this question because I was using the former method and wanted them to plot on the same figure, so your question was actually my answer.

I created a bundle with 3 apps for the finder toolbar. The other two apps do:

This is now possible with PHP 5.6.x, using the ... operator (also known as splat operator in some languages):

Example:

function addDateIntervalsToDateTime( DateTime $dt, DateInterval ...$intervals )
{
    foreach ( $intervals as $interval ) {
        $dt->add( $interval );
    }
    return $dt;
}

addDateIntervaslToDateTime( new DateTime, new DateInterval( 'P1D' ), 
        new DateInterval( 'P4D' ), new DateInterval( 'P10D' ) );

Saving a Keras model:

model = ...  # Get model (Sequential, Functional Model, or Model subclass)
model.save('path/to/location')

Loading the model back:

from tensorflow import keras
model = keras.models.load_model('path/to/location')

I was facing same issue. I tried everything possible for a day, but nothing worked. The dependency which was causing problem was using lower compile sdk, target sdk and min sdk. I created library module for the project, copied all the sources and matched the sdk versions with application sdk versions. And finally it worked like a charm.

You should use view models and forget about ViewBag Think of it as if it didn't exist. You will see how easier things will become. So define a view model:

public class MyViewModel
{
    public int SelectedCategoryId { get; set; }
    public IEnumerable<SelectListItem> Categories { get; set; } 
}

and then populate this view model from the controller:

public ActionResult NewsEdit(int ID, dms_New dsn)
{
    var dsn = (from a in dc.dms_News where a.NewsID == ID select a).FirstOrDefault();
    var categories = (from b in dc.dms_NewsCategories select b).ToList();

    var model = new MyViewModel
    {
        SelectedCategoryId = dsn.NewsCategoriesID,
        Categories = categories.Select(x => new SelectListItem
        {
            Value = x.NewsCategoriesID.ToString(),
            Text = x.NewsCategoriesName
        })
    };
    return View(model);
}

and finally in your view use the strongly typed DropDownListFor helper:

@model MyViewModel

@Html.DropDownListFor(
    x => x.SelectedCategoryId,
    Model.Categories
)

map HTTP request header Content-Type, handle request body.

• @RequestParam ? application/x-www-form-urlencoded,

• @RequestBody ? application/json,

• @RequestPart ? multipart/form-data,

• RequestParam (Spring Framework 5.1.9.RELEASE API)

  map to query parameters, form data, and parts in multipart requests.

  RequestParam is likely to be used with name-value form fields

• RequestBody (Spring Framework 5.1.9.RELEASE API)

  bound to the body of the web request. The body of the request is passed through an HttpMessageConverter to resolve the method argument depending on the content type of the request. (e.g. JSON, XML)

• RequestPart (Spring Framework 5.1.9.RELEASE API)

  used to associate the part of a "multipart/form-data" request

  RequestPart is likely to be used with parts containing more complex content

• HttpMessageConverter (Spring Framework 5.1.9.RELEASE API)

  a converter that can convert from and to HTTP requests and responses.

You won't be able to send a message through other people mail servers. Check with your host provider how to send emails. Try to send an email from your server without PHP, you can use any email client like Outook. Just after it works, try to configure PHP.ini with your email client SMTP (sending e-mail) configuration.

use this css for height

height: calc(100vh) !important;

This will make the video to have 100% vertical height available.

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

You can try this UITextfield subclass which you can set a condition for the text to dynamically change the UIReturnKey:

Open chrome, go to chrome://settings/languages

On the left, you should see a list of languages. Use mouse to drag the language you want to the top, that will change the order for the values in Accept-language of requests.

If you still don't see the language you prefer, it may be cookies. Go to cookies and clean it up you should be good.

Try this. It worked for me:

- (void) viewDidLoad
{
  [super viewDidLoad];

  // Without ARC
  //self.tableView.tableFooterView = [[[UIView alloc] init] autorelease];

  // With ARC, tried on Xcode 5
  self.tableView.tableFooterView = [UIView new];
}

If you want to get a floating point value with two decimal places limited at the time of calling input,

Check this out ~

a = eval(format(float(input()), '.2f'))   # if u feed 3.1415 for 'a'.
print(a)                                  # output 3.14 will be printed.

something like this would probably work

class MyClass:
    def __init__(self,x,y,z):
       self.x = x
       self.y = y
       self.z = z
    def __iter__(self): #overridding this to return tuples of (key,value)
       return iter([('x',self.x),('y',self.y),('z',self.z)])

dict(MyClass(5,6,7)) # because dict knows how to deal with tuples of (key,value)

You can write that in single line, but it's not something that someone would be able to read. Keep it like you already wrote it, it's already beautiful by itself.

If you have too much if/else constructs, you may think about using of different datastructures, like Dictionaries (to look up keys) or Collection (to run conditional LINQ queries on it)

Below worked for me,

- name: Ansible delete html directory
  file:
   path: /var/www/html
   state: directory

1) Maybe oveflow: hidden; will do the trick?

2) You need to set the size of each div with the text and button so that each of these divs have the same height. Then for your button:

button {
  position: absolute;
  bottom: 0;
}

import os#must import this library
if os.path.exists('TwitterDB.csv'):
        os.remove('TwitterDB.csv') #this deletes the file
else:
        print("The file does not exist")#add this to prevent errors

I had a similar problem, and instead of overwriting my existing file using the different 'modes', I just deleted the file before using it again, so that it would be as if I was appending to a new file on each run of my code.

See String.lastIndexOf method

Make sure all your tables have one primary key. I forgot to add a primary key to one table and that solved this problem for me. :)

You don't want to have the collision check code inside the painting code. The painting needs to be fast. Collision can go in the game loop. Therefore you need an internal representation of the objects independent of their sprites.

ajavascript have two type of annotation for fetching javascript Object properties:

Obj = {};

1) (.) annotation eg. Obj.id this will only work if the object already have a property with name 'id'

2) ([]) annotation eg . Obj[id] here if the object does not have any property with name 'id',it will create a new property with name 'id'.

so for below example:

A new property will be created always when you write Obj[name]. And if the property already exist with the same name it will override it.

const obj = {}
    jQuery(itemsFromDom).each(function() {
      const element = jQuery(this)
      const name = element.attr('id')
      const value = element.attr('value')
      // This will work
      obj[name]= value;
    })

I have the same problem. I avoid it with remove.packages("Package making this confusion") and it works. In my case, I don't need the second package, so that is not a very good idea.

Try this: if you need pass values between the activities you use this...

This is code for Main_Activity put the values to intent

 String name="aaaa";
 Intent intent=new Intent(Main_Activity.this,Other_Activity.class);
 intent.putExtra("name", name);
 startActivity(intent);

This code for Other_Activity and get the values form intent

    Bundle b = new Bundle();
    b = getIntent().getExtras();
    String name = b.getString("name");

Use libcurl, here is a simple example.

EDIT: If this is about starting a web browser from C++, you can invoke a shell command with system on a POSIX system:

system("<mybrowser> http://google.com");

By replacing <mybrowser> with the browser you want to launch.

You can use following methods to get current date in milliseconds.

[[NSDate date] timeIntervalSince1970];

OR

double CurrentTime = CACurrentMediaTime();

It's not called null as in other languages, but None. There is always only one instance of this object, so you can check for equivalence with x is None (identity comparison) instead of x == None, if you want.

This is my version referring @Virako 's code snippet

def adjust_column_width_from_col(ws, min_row, min_col, max_col):

        column_widths = []

        for i, col in \
                enumerate(
                    ws.iter_cols(min_col=min_col, max_col=max_col, min_row=min_row)
                ):

            for cell in col:
                value = cell.value
                if value is not None:

                    if isinstance(value, str) is False:
                        value = str(value)

                    try:
                        column_widths[i] = max(column_widths[i], len(value))
                    except IndexError:
                        column_widths.append(len(value))

        for i, width in enumerate(column_widths):

            col_name = get_column_letter(min_col + i)
            value = column_widths[i] + 2
            ws.column_dimensions[col_name].width = value

And how to use is as follows,

adjust_column_width_from_col(ws, 1,1, ws.max_column)

Stop seeding the generator every time. Pull the srand call out of the loop

I use to use the Do, Loop a lot but I have started using a Sub or a Function that I could exit out of instead. It just seemed cleaner to me. If any variables you need are not global you will need to pass them to the Sub also.

For i=1 to N
 DoWork i
Next

Sub DoWork(i)
    [Code]
    If Condition1 Then
      Exit Sub
    End If

    [MoreCode]
    If Condition2 Then
      Exit Sub
    End If

    [MoreCode]
    If Condition2 Then
      Exit Sub
    End If

    [...]
End Sub

let obj = MyObject();

elem.someEvent( function(){ obj.func(param) } );

//calls the MyObject.func, passing the param.

This may be an old response but I used some examples from this post to create a comparator that would sort an ArrayList of HashMap<String, String> by one object in the list, that being the timestamp.

I have these objects:

ArrayList<Map<String, String>> alList = new ArrayList<Map<String, String>>();

The map objects are as follows:

Map<String, Object> map = new HashMap<>();
        // of course this is the actual formatted date below in the timestamp
        map.put("timestamp", "MM/dd/yyyy HH:mm:ss"); 
        map.put("item1", "my text goes here");
        map.put("item2", "my text goes here");

That mapping is what I use to load all my objects into the array list, using the alList.add(map) function, within a loop.

Now, I created my own comparator:

import org.joda.time.DateTime;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.HashMap;
import java.util.Map;

 public class DateSorter implements Comparator {
     public int compare(Object firstObjToCompare, Object secondObjToCompare) {
    String firstDateString = ((HashMap<String, String>) firstObjToCompare).get("timestamp");
    String secondDateString = ((HashMap<String, String>) secondObjToCompare).get("timestamp");

    if (secondDateString == null || firstDateString == null) {
        return 0;
    }

    // Convert to Dates
    DateTimeFormatter dtf = DateTimeFormat.forPattern("MM/dd/yyyy HH:mm:ss");
    DateTime firstDate = dtf.parseDateTime(firstDateString);
    DateTime secondDate = dtf.parseDateTime(secondDateString);

    if (firstDate.isAfter(secondDate)) return -1;
    else if (firstDate.isBefore(secondDate)) return 1;
    else return 0;
    }
}

I can now just call the Comparator at any time on the array and it will sort my array, giving me the Latest timestamp in position 0 (top of the list) and the earliest timestamp at the end of the list. New posts get put to the top basically.

Collections.sort(alList, new DateSorter());

This may help someone out, which is why I posted it. Take into consideration the return statements within the compare() function. There are 3 types of results. Returning 0 if they are equal, returning >0 if the first date is before the second date and returning <0 if the first date is after the second date. If you want your list to be reversed, then just switch those two return statements! Simple =]

The trick is defining the masksToBounds property of your view's layer properly:

view.layer.masksToBounds = NO;

and it should work.

I like articles from Nat Pryce. Here are the links:

• Avoiding Nulls with Polymorphic Dispatch
• Avoiding Nulls with "Tell, Don't Ask" Style

In the articles there is also a link to a Git repository for a Java Maybe Type which I find interesting, but I don't think it alone could decrease the checking code bloat. After doing some research on the Internet, I think != null code bloat could be decreased mainly by careful design.

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:

interface TestObject {
  name:string;
  value:number;
}

@Component({
  selector: 'app',
  template: `
      <h4>Select Object via 2-way binding</h4>

      <select [ngModel]="selectedObject | json" (ngModelChange)="updateSelectedValue($event)">
        <option *ngFor="#o of objArray" [value]="o | json" >{{o.name}}</option>
      </select>

      <h4>You selected:</h4> {{selectedObject }}
  `,
  directives: [FORM_DIRECTIVES]
})
export class App {
  objArray:TestObject[];
  selectedObject:TestObject;
  constructor(){
    this.objArray = [{name: 'foo', value: 1}, {name: 'bar', value: 1}];
    this.selectedObject = this.objArray[1];
  }
  updateSelectedValue(event:string): void{
    this.selectedObject = JSON.parse(event);
  }
}

As the official docs of redux suggest, better to export the unconnected component as well.

In order to be able to test the App component itself without having to deal with the decorator, we recommend you to also export the undecorated component:

import { connect } from 'react-redux'

// Use named export for unconnected component (for tests)
export class App extends Component { /* ... */ }
 
// Use default export for the connected component (for app)
export default connect(mapStateToProps)(App)

Since the default export is still the decorated component, the import statement pictured above will work as before so you won't have to change your application code. However, you can now import the undecorated App components in your test file like this:

// Note the curly braces: grab the named export instead of default export
import { App } from './App'

And if you need both:

import ConnectedApp, { App } from './App'

In the app itself, you would still import it normally:

import App from './App'

You would only use the named export for tests.

NSString objects are immutable (they can't be changed), but there is a mutable subclass, NSMutableString, that gives you several methods for replacing characters within a string. It's probably your best bet.

The important thing about JSON is to keep data transfer encrypted for security reasons. No doubt that JSON is much much faster then XML. I have seen XML take 100ms where as JSON only took 60ms. JSON data is easy to manipulate.

Answer is to allow all requests in WebSecurityConfigurerAdapter as below.

you can do this in existing class or in new class.

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().permitAll();
    }

Please note : If ther is existing GlobalMethodSecurityConfiguration class, you must disable it.

add persist security info=True; in connection string.

A good option is to use an API like Docverter. Docverter will allow you to convert HTML to PDF or DOCX using an API.

This works for DLLs locked by other processes. This routine will not find out for example that a text file is locked by a word process.

According to the official documentation on sitemaps.org it needs to be a full URL:

You can specify the location of the Sitemap using a robots.txt file. To do this, simply add the following line including the full URL to the sitemap:

Sitemap: http://www.example.com/sitemap.xml

Answer provided by @jAndy should work but in Firefox you may face problem, window.location.reload(1); might not work, that's my personal experience.

So i would like to suggest:

setTimeout(function() { window.location=window.location;},5000);

This is tested and works fine.

For this is important to understand the difference between Merge and Rebase.

Rebases are how changes should pass from the top of hierarchy downwards and merges are how they flow back upwards.

For details refer - http://www.derekgourlay.com/archives/428

$articles =DB::table('articles')
                ->join('categories','articles.id', '=', 'categories.id')
                ->join('user', 'articles.user_id', '=', 'user.id')
                ->select('articles.id','articles.title','articles.body','user.user_name', 'categories.category_name')
                ->get();
return view('myarticlesview',['articles'=>$articles]);

I would propose simply:

def get_digest(file_path):
    h = hashlib.sha256()

    with open(file_path, 'rb') as file:
        while True:
            # Reading is buffered, so we can read smaller chunks.
            chunk = file.read(h.block_size)
            if not chunk:
                break
            h.update(chunk)

    return h.hexdigest()

All other answers here seem to complicate too much. Python is already buffering when reading (in ideal manner, or you configure that buffering if you have more information about underlying storage) and so it is better to read in chunks the hash function finds ideal which makes it faster or at lest less CPU intensive to compute the hash function. So instead of disabling buffering and trying to emulate it yourself, you use Python buffering and control what you should be controlling: what the consumer of your data finds ideal, hash block size.

The most secure way (in terms of special character and data type handling) is using json_encode():

var spge = <?php echo json_encode($cname); ?>;

If the IBM mainframe JCL has some extra characters or numbers at the end of the name of unix script being called then it can throw such error.

Assume logs are already put to stdout/stderr, and have systemd unit's log in /var/log/syslog

You just have to include following script.

<script language="javascript" type="text/javascript">  
        var xmlHttp  
        function showState(str)
        {
            //if you want any text box value you can get it like below line. 
            //just make sure you have specified its "id" attribute
            var name=document.getElementById("id_attr").value;
            if (typeof XMLHttpRequest != "undefined")
            {
              xmlHttp= new XMLHttpRequest();
            }
            var url="forwardPage.jsp";
            url +="?count1=" +str+"&count2="+name";
            xmlHttp.onreadystatechange = stateChange;
            xmlHttp.open("GET", url, true);
            xmlHttp.send(null);
        }
        function stateChange()
        {   
            if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
            {   
                document.getElementById("div_id").innerHTML=xmlHttp.responseText   
            }   
        }
      </script>

So if you got the code, let me tell you, div_id will be id of div tag where you have to show your result. By using this code, you are passing parameters to another page. Whatever the processing is done there will be reflected in div tag whose id is "div_id". You can call showState(this.value) on "onChange" event of any control or "onClick" event of button not submit. Further queries will be appreciated.

I'm a little late, but I have a little snippet to do this, it essentially maintains all of JScripts truthey/falsey/filthy-ness but includes "false" as an acceptible value for false.

I prefer this method to the ones mentioned because it doesn't rely on a 3rd party to parse the code (i.e: eval/JSON.parse), which is overkill in my mind, it's short enough to not require a utility function and maintains other truthey/falsey conventions.

var value = "false";
var result = (value == "false") != Boolean(value);

// value = "true"  => result = true
// value = "false" => result = false
// value = true    => result = true
// value = false   => result = false
// value = null    => result = false
// value = []      => result = true
// etc..

According to w3.org the value attribute of the number input is defined as a floating-point number. The syntax of the floating-point number seems to only accept dots as decimal separators.

I've listed a few options below that might be helpful to you:

1. Using the pattern attribute

With the pattern attribute you can specify the allowed format with a regular expression in a HTML5 compatible way. Here you could specify that the comma character is allowed and a helpful feedback message if the pattern fails.

<input type="number" pattern="[0-9]+([,\.][0-9]+)?" name="my-num"
           title="The number input must start with a number and use either comma or a dot as a decimal character."/>

Note: Cross-browser support varies a lot. It may be complete, partial or non-existant..

2. JavaScript validation

You could try to bind a simple callback to for example the onchange (and/or blur) event that would either replace the comma or validate all together.

3. Disable browser validation ##

Thirdly you could try to use the formnovalidate attribute on the number inputs with the intention of disabling browser validation for that field all together.

<input type="number" formnovalidate />

4. Combination..?

<input type="number" pattern="[0-9]+([,\.][0-9]+)?" 
           name="my-num" formnovalidate
           title="The number input must start with a number and use either comma or a dot as a decimal character."/>

Always state the workbook, worksheet and the cell/range.

For example:

Thisworkbook.Worksheets("fred").cells(1,1)
Workbooks("bob").Worksheets("fred").cells(1,1)

Because end users will always just click buttons and as soon as the focus moves off of the workbook the code wants to work with then things go completely wrong.

And never use the index of a workbook.

Workbooks(1).Worksheets("fred").cells(1,1)

You don't know what other workbooks will be open when the user runs your code.

Seems like you upgraded PHP to newer version and old .ini files are still pointing to old location.

The solution: find out where are modules located now

ls -l /usr/lib/php5

There should be a directory similar to old 20090626. In my case it is now 20131226

The .ini files giving you an error are located at /etc/php5/cli/conf.d/

Just edit those .ini files which module gives you an error. For example, in case the error is for mcrypt module:

sudo vi /etc/php5/cli/conf.d/20-mcrypt.ini

Change the line:

extension=/usr/lib/php5/20090626/mcrypt.so

to reflect the new path for .so file. In my case the correct path should be:

extension=/usr/lib/php5/20131226/mcrypt.so

That's it! The error is gone. Ofc you'd have to do it with each module giving you an error.

adding to CMS's answer, this is a more generic approach of toggle_visibility I've just used myself:

function toggle_visibility(className,display) {
   var elements = getElementsByClassName(document, className),
       n = elements.length;
   for (var i = 0; i < n; i++) {
     var e = elements[i];

     if(display.length > 0) {
       e.style.display = display;
     } else {
       if(e.style.display == 'block') {
         e.style.display = 'none';
       } else {
         e.style.display = 'block';
       }
     }
  }
}

Did you try using t.Text?

git log -n1 --format="Last committed item in this release was by %an, `git log -n1 --format=%at | awk '{print strftime("%y%m%d%H%M",$1)}'`, message: %s (%h) [%d]"

There are multiple ways

return \Response::json(['hello' => $value], STATUS_CODE);

return response()->json(['hello' => $value], STATUS_CODE);

where STATUS_CODE is your HTTP status code you want to send. Both are identical.

if you are using Eloquent model, then simple return will also be auto converted in JSON by default like,

return User::all();

try this:

SELECT ReportId, Email = 
    STUFF((SELECT ', ' + Email
           FROM your_table b 
           WHERE b.ReportId = a.ReportId 
          FOR XML PATH('')), 1, 2, '')
FROM your_table a
GROUP BY ReportId

You want to check if an object is NULL/empty. Being NULL and empty are not the same. Like Justin and Brian have already mentioned, in C++ NULL is an assignment you'd typically associate with pointers. You can overload operator= perhaps, but think it through real well if you actually want to do this. Couple of other things:

1. In C++ NULL pointer is very different to pointer pointing to an 'empty' object.
2. Why not have a bool IsEmpty() method that returns true if an object's variables are reset to some default state? Guess that might bypass the NULL usage.
3. Having something like A* p = new A; ... p = NULL; is bad (no delete p) unless you can ensure your code will be garbage collected. If anything, this'd lead to memory leaks and with several such leaks there's good chance you'd have slow code.
4. You may want to do this class Null {}; Null _NULL; and then overload operator= and operator!= of other classes depending on your situation.

Perhaps you should post us some details about the context to help you better with option 4.

I thing these two links have a wide discussion on your problem related stuff. fb:ref clear cashes by calling

fbml.refreshRefUrl

like this

<tt>fbml.refreshRefUrl("http://www.mysite.com/someurl.php")

You can study the related stuff from here fb:ref. I hope it will work for you

$("#SelectedCountryId_option_selected")[0].textContent

this worked for me, here instead of [0], pass the selected index of your drop down list.

I was facing the same problem when import projects into IntelliJ.

for in my case first, check SDK details and check you have configured JDK correctly or not.

Go to File-> Project Structure-> platform Settings-> SDKs

Check your JDK is correct or not.

Next, I Removed project from IntelliJ and delete all IntelliJ and IDE related files and folder from the project folder (.idea, .settings, .classpath, dependency-reduced-pom). Also, delete the target folder and re-import the project.

The above solution worked in my case.

Yes, ensure like finally guarantees that the block will be executed. This is very useful for making sure that critical resources are protected e.g. closing a file handle on error, or releasing a mutex.

While writing to S3, you need to specify the length of S3 object to be sure that there are no out of memory errors.

Using IOUtils.toByteArray(stream) is also prone to OOM errors because this is backed by ByteArrayOutputStream

So, the best option is to first write the inputstream to a temp file on local disk and then use that file to write to S3 by specifying the length of temp file.

Yes, its possible to have array of objects in PHP.

class MyObject {
  private $property;

  public function  __construct($property) {
    $this->Property = $property;
  }
}
$ListOfObjects[] = new myObject(1); 
$ListOfObjects[] = new myObject(2); 
$ListOfObjects[] = new myObject(3); 
$ListOfObjects[] = new myObject(4); 

print "<pre>";
print_r($ListOfObjects);
print "</pre>";

This will do it if you only want the first "B" value, you can sub a cell address for "B" if you want to make it more generic.

=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(B2:B6)="B",0)),1)

To use this based on two columns, just concatenate inside the match:

=INDEX(A2:A6,SUMPRODUCT(MATCH(TRUE,(A2:A6&B2:B6)=("3"&"B"),0)),1)

You need to give the range a -1 step

 for i in range(10,0,-1):
    print i

If the use of EditText is not mandatory, you can implement this behavior easily with the new material components:

<com.google.android.material.textfield.TextInputLayout
            style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/hint_field"
            app:endIconDrawable="@drawable/ic_close_black_24dp"
            app:endIconMode="clear_text"
            app:endIconTint="@color/black">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/hint_value"
                android:maxLines="1"
                android:text="@{itemModel.value}" />

        </com.google.android.material.textfield.TextInputLayout>

You only have to specify the drawable you want for the button that will clear the text and the action that it will execute. To clear the text, you can use iconMode="clear_text", but also "password_toggle" is available.

Petr Krampl's answer is the best in my opinion, but more needs to be said about the nature of loops and how to optimize the use of the system. Beginners who happen upon this thread may be further confused by the logical and algorithmic errors in the question and existing answers.

First, let's look at what your code does as you originally wrote it:

while True:
    test = 0
    if test == 5:
        break
    test = test - 1

If you say while True in a loop context, normally your intention is to stay in the loop forever. If that's not your intention, you should consider other options for the structure of the loop. Petr Krampl showed you a perfectly reasonable way to handle this that's much more clear to someone else who may read your code. In addition, it will be more clear to you several months later should you need to revisit your code to add or fix something. Well-written code is part of your documentation. There are usually multiple ways to do things, but that doesn't make all of the ways equally valid in all contexts. while true is a good example of this especially in this context.

Next, we will look at the algorithmic error in your original code. The very first thing you do in the loop is assign 0 to test. The very next thing you do is to check if the value of test is 5, which will never be the case unless you have multiple threads modifying the same memory location. Threading is not in scope for this discussion, but it's worth noting that the code could technically work, but even with multiple threads a lot would be missing, e.g. semaphores. Anyway, you will sit in this loop forever regardless of the fact that the sentinel is forcing an infinite loop.

The statement test = test - 1 is useless regardless of what it does because the variable is reset at the beginning of the next iteration of the loop. Even if you changed it to be test = 5, the loop would still be infinite because the value is reset each time. If you move the initialization statement outside the loop, then it will at least have a chance to exit. What you may have intended was something like this:

test = 0
while True:
    test = test - 1
    if test == 5:
        break

The order of the statements in the loop depends on the logic of your program. It will work in either order, though, which is the main point.

The next issue is the potential and probable logical error of starting at 0, continually subtracting 1, and then comparing with a positive number. Yes, there are occasions where this may actually be what you intend to do as long as you understand the implications, but this is most likely not what you intended. Newer versions of python will not wrap around when you reach the 'bottom' of the range of an integer like C and various other languages. It will let you continue to subtract 1 until you've filled the available memory on your system or at least what's allocated to your process. Look at the following script and the results:

test = 0

while True:
    test  -= 1

    if test % 100 == 0:
        print "Test = %d" % test

    if test == 5:
        print "Test = 5"
        break

which produces this:

Test = -100
Test = -200
Test = -300
Test = -400
...
Test = -21559000
Test = -21559100
Test = -21559200
Test = -21559300
...

The value of test will never be 5, so this loop will never exit.

To add to Petr Krampl's answer, here's a version that's probably closer to what you actually intended in addition to exiting the loop after a certain period of time:

import time

test = 0
timeout = 300   # [seconds]

timeout_start = time.time()

while time.time() < timeout_start + timeout:
    if test == 5:
        break
    test -= 1

It still won't break based on the value of test, but this is a perfectly valid loop with a reasonable initial condition. Further boundary checking could help you to avoid execution of a very long loop for no reason, e.g. check if the value of test is less than 5 upon loop entry, which would immediately break the loop.

One other thing should be mentioned that no other answer has addressed. Sometimes when you loop like this, you may not want to consume the CPU for the entire allotted time. For example, say you are checking the value of something that changes every second. If you don't introduce some kind of delay, you would use every available CPU cycle allotted to your process. That's fine if it's necessary, but good design will allow a lot of programs to run in parallel on your system without overburdening the available resources. A simple sleep statement will free up the vast majority of the CPU cycles allotted to your process so other programs can do work.

The following example isn't very useful, but it does demonstrate the concept. Let's say you want to print something every second. One way to do it would be like this:

import time

tCurrent = time.time()

while True:
    if time.time() >= tCurrent + 1:
        print "Time = %d" % time.time()
        tCurrent = time.time()

The output would be this:

Time = 1498226796
Time = 1498226797
Time = 1498226798
Time = 1498226799

And the process CPU usage would look like this:

That's a huge amount of CPU usage for doing basically no work. This code is much nicer to the rest of the system:

import time

tCurrent = time.time()

while True:
    time.sleep(0.25) # sleep for 250 milliseconds
    if time.time() >= tCurrent + 1:
        print "Time = %d" % time.time()
        tCurrent = time.time()

The output is the same:

Time = 1498226796
Time = 1498226797
Time = 1498226798
Time = 1498226799

and the CPU usage is way, way lower:

• DTR - Data Terminal Ready
• DSR - Data Set Ready
• RTS - Request To Send
• CTS - Clear To Send

There are multiple ways of doing things because there were never any protocols built into the standards. You use whatever ad-hoc "standard" your equipment implements.

Just based on the names, RTS/CTS would seem to be a natural fit. However, it's backwards from the needs that developed over time. These signals were created at a time when a terminal would batch-send a screen full of data, but the receiver might not be ready, thus the need for flow control. Later the problem would be reversed, as the terminal couldn't keep up with data coming from the host, but the RTS/CTS signals go the wrong direction - the interface isn't orthogonal, and there's no corresponding signals going the other way. Equipment makers adapted as best they could, including using the DTR and DSR signals.

EDIT

To add a bit more detail, its a two level hierarchy so "officially" both must happen for communication to take place. The behavior is defined in the original CCITT (now ITU-T) standard V.28.

The DCE is a modem connecting between the terminal and telephone network. In the telephone network was another piece of equipment which split off to the data network, eg. X.25.

The modem has three states: Powered off, Ready (Data Set Ready is true), and connected (Data Carrier Detect)

The terminal can't do anything until the modem is connected.

When the modem wants to send data, it raises RTS and the modem grants the request with CTS. The modem lowers CTS when its internal buffer is full.

So nostalgic!

Simple to me is like this:

$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"

"$Time,$Description"|Add-Content -Path $File # Keep no space between content variables

If you have a lot of columns, then create a variable like $NewRow like:

$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"
$NewRow = "$Time,$Description" # No space between variables, just use comma(,).

$NewRow | Add-Content -Path $File # Keep no space between content variables

Please note the difference between Set-Content (overwrites the existing contents) and Add-Content (appends to the existing contents) of the file.

Without knowing the exact regex implementation you're making use of, I can only give general advice. (The syntax I will be perl as that's what I know, some languages will require tweaking)

Looking at ABC: (z) jan 02 1999 \n

• The first thing to match is ABC: So using our regex is /ABC:/

• You say ABC is always at the start of the string so /^ABC/ will ensure that ABC is at the start of the string.

• You can match spaces with the \s (note the case) directive. With all directives you can match one or more with + (or 0 or more with *)

• You need to escape the usage of ( and ) as it's a reserved character. so \(\)

• You can match any non space or newline character with .

• You can match anything at all with .* but you need to be careful you're not too greedy and capture everything.

So in order to capture what you've asked. I would use /^ABC:\s*\(.+?\)\s*(.+)$/

Which I read as:

Begins with ABC:

May have some spaces

has (

has some characters

has )

may have some spaces

then capture everything until the end of the line (which is $).

I highly recommend keeping a copy of the following laying about http://www.cheatography.com/davechild/cheat-sheets/regular-expressions/

There's a simpler way than a whole bunch of if statements. Use the or (||) operator.

function getBrowserDimensions() {
  return {
    width: (window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth),
    height: (window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight)
  };
}

var browser_dims = getBrowserDimensions();

alert("Width = " + browser_dims.width + "\nHeight = " + browser_dims.height);

Regarding [NSException raise:format:]. For those coming from a Java background, you will recall that Java distinguishes between Exception and RuntimeException. Exception is a checked exception, and RuntimeException is unchecked. In particular, Java suggests using checked exceptions for "normal error conditions" and unchecked exceptions for "runtime errors caused by a programmer error." It seems that Objective-C exceptions should be used in the same places you would use an unchecked exception, and error code return values or NSError values are preferred in places where you would use a checked exception.

Two ways:

1. Edit the properties of the service and set the Log On user. The appropriate right will be automatically assigned.

2. Set it manually: Go to Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment. Edit the item "Log on as a service" and add your domain user there.

My solution to not having sessionStorage transferable over tabs was to create a localProfile and bang off this variable. If this variable is set but my sessionStorage variables arent go ahead and reinitialize them. When user logs out window closes destroy this localStorage variable

Its very simple you just add this script,

$("#mydate").datepicker({ dateFormat: "yy-mm-dd"}).datepicker("setDate", new Date());

Here, setDate set today date & dateFormat define which format you want set or show.

Hope its simple script work..

A simple loop should be working:

for file in /var/*
do
    #whatever you need with "$file"
done

See bash filename expansion

A package called styled-components can solve this problem in an ELEGANT way.
