Programs & Examples On #Papi

We started getting this error on the production server after deploying the application migrated from 4.6.1 to 4.7.2.

We noticed that the .NET framework 4.7.2 was not installed there. In order to solve this issue we did the following steps:

1. Installed the .NET Framework 4.7.2 from:

   https://support.microsoft.com/en-us/help/4054530/microsoft-net-framework-4-7-2-offline-installer-for-windows

2. Restarted the machine

3. Confirmed the .NET Framework version with the help of How do I find the .NET version?

Running the application again with the .Net Framework 4.7.2 version installed on the machine fixed the issue.

Example of how it's implemented on wellsfargo.com:

try {
 if (window.document.documentElement.getAttribute("webdriver")) return !+[]
} catch (IDLMrxxel) {}
try {
 if ("_Selenium_IDE_Recorder" in window) return !+""
} catch (KknKsUayS) {}
try {
 if ("__webdriver_script_fn" in document) return !+""

I was able to resolve this issue by reinstalling Nuget Package Manager via Tools -> Extensions and Updates

As the instruction said "might need gpg2"

In mac, you can try install it with homebrew

$ brew install gpg2 

In my case this error appeared when I asigned to both dynamic created controls (combobox), same created control from other class.

//dynamic created controls
ComboBox combobox1 = ManagerControls.myCombobox1;
...some events

ComboBox combobox2 = ManagerControl.myComboBox2;
...some events

.

//method in constructor
public static void InitializeDynamicControls()
{
     ComboBox cb = new ComboBox();
     cb.Background = new SolidColorBrush(Colors.Blue);
     ...
     cb.Width = 100;
     cb.Text = "Select window";
        
     ManagerControls.myCombobox1 = cb;
     ManagerControls.myComboBox2 = cb; // <-- error here
}

Solution: create another ComboBox cb2 and assign it to ManagerControls.myComboBox2.

I hope I helped someone.

If you are on ubuntu, just install pyqt5 with apt-get command:

    sudo apt-get install python3-pyqt5   # for python3

or

    sudo apt-get install python-pyqt5    # for python2

However, on Ubuntu 14.04 the python-pyqt5 package is left out [source] and need to be installed manually [source]

WebDav-SchmebDav.. ..make sure you create the url with the ID correctly. Don't send it like http://www.fluff.com/api/Fluff?id=MyID, send it like http://www.fluff.com/api/Fluff/MyID.

Eg.

PUT http://www.fluff.com/api/Fluff/123 HTTP/1.1
Host: www.fluff.com
Content-Length: 11

{"Data":"1"}

This was busting my balls for a small eternity, total embarrassment.

If that message is bother you, You need run Visual Studio with administrative rights to apply this direction on Visual Studio.

Tools-> Options-> Debugging-> Symbols and select check in a box "Microsoft Symbol Servers", mark load all modules then click Load all Symbols.

Everything else Visual Studio will do it for you, and you will have this message under Debug in Output window "Native' has exited with code 0 (0x0)"

Yes, you can just change the port to to any number. For instance change Listen 80 to Listen 81 in the httpd.conf file. Now try with http://localhost:81 and it will respond on port 81!!

You have forgotten a * between -3.7 and (prof[x]).

Thus:

for x in range(len(prof)):
    PB = 2.25 * (1 - math.pow(math.e, (-3.7 * (prof[x])/2.25))) * (math.e, (0/2.25)))

Also, there seems to be missing an ( as I count 6 times ( and 7 times ), and I think (math.e, (0/2.25)) is missing a function call (probably math.pow, but thats just a wild guess).

Try adding a cachebreaker at the end of the url:

newImage.src = "http://localhost/image.jpg?" + new Date().getTime();

This will append the current timestamp automatically when you are creating the image, and it will make the browser look again for the image instead of retrieving the one in the cache.

Some time ago I wrote simple Webcam Capture API which can be used for that. The project is available on Github.

Example code:

Webcam webcam = Webcam.getDefault();
webcam.open();
try {
  ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));
} catch (IOException e) {
  e.printStackTrace();
} finally {
  webcam.close();
}

Make sure you have .NET 4.6.2 Developer Pack for VS installed and then pull in System.ValueTuple package from NuGet.

   extend = function(destination, source) {   
          for (var property in source) {
            destination[property] = source[property];
          }
          return destination;
    };

Extending JavaScript

You could also add filters into the for loop.

In the case like me that you aquired a repo and are now switching the remote origin to a different repo, a new empty one...

So you have your repo and all the branches inside, but you still need to checkout those branches for the git push --all command to actually push those too.

You should do this before you push:

for remote in `git branch -r | grep -v master `; do git checkout --track $remote ; done

Followed by

git push --all

I should be able to accomplish this through standard java string manipulation, nothing Android or TextView specific.

Something like:

String upperString = myString.substring(0, 1).toUpperCase() + myString.substring(1).toLowerCase();

Although there are probably a million ways to accomplish this. See String documentation.

EDITED I added the .toLowerCase()

This might work for you:

printf "{new\nto\nlinux}" | paste -sd' '            
{new to linux}

or:

printf "{new\nto\nlinux}" | tr '\n' ' '            
{new to linux}

or:

printf "{new\nto\nlinux}" |sed -e ':a' -e '$!{' -e 'N' -e 'ba' -e '}' -e 's/\n/ /g'
{new to linux}

select DATEDIFF(dd, '12/30/1899', mydatefield)

I found the solution of this problem and i should work i'm sure about this because i also face the same problem

here is my solution----->

var request = require('request');

//set url
var url = 'http://localhost:8088/example';

//set header
var headers = {
    'Authorization': 'Your authorization'
};

//set form data
var form = {first_name: first_name, last_name: last_name};

//set request parameter
request.post({headers: headers, url: url, form: form, method: 'POST'}, function (e, r, body) {

    var bodyValues = JSON.parse(body);
    res.send(bodyValues);
});

Sometimes another software can be holding this door and it can be the cause of this conflict, try change the door on the server.xml.

its work for me

$attachment_location = "filePath";
if (file_exists($attachment_location)) {

    header($_SERVER["SERVER_PROTOCOL"] . " 200 OK");
    header("Cache-Control: public"); // needed for internet explorer
    header("Content-Type: application/zip");
    header("Content-Transfer-Encoding: Binary");
    header("Content-Length:".filesize($attachment_location));
    header("Content-Disposition: attachment; filename=filePath");
    readfile($attachment_location);
    die();
} else {
    die("Error: File not found.");
}

You can use:

String.prototype.replaceAll = function(search, replace) {
if (replace === undefined) {
    return this.toString();
}
return this.split(search).join(replace);
}

For the multi-class case, everything you need can be found from the confusion matrix. For example, if your confusion matrix looks like this:

Then what you're looking for, per class, can be found like this:

Using pandas/numpy, you can do this for all classes at once like so:

FP = confusion_matrix.sum(axis=0) - np.diag(confusion_matrix)  
FN = confusion_matrix.sum(axis=1) - np.diag(confusion_matrix)
TP = np.diag(confusion_matrix)
TN = confusion_matrix.values.sum() - (FP + FN + TP)

# Sensitivity, hit rate, recall, or true positive rate
TPR = TP/(TP+FN)
# Specificity or true negative rate
TNR = TN/(TN+FP) 
# Precision or positive predictive value
PPV = TP/(TP+FP)
# Negative predictive value
NPV = TN/(TN+FN)
# Fall out or false positive rate
FPR = FP/(FP+TN)
# False negative rate
FNR = FN/(TP+FN)
# False discovery rate
FDR = FP/(TP+FP)

# Overall accuracy
ACC = (TP+TN)/(TP+FP+FN+TN)

Just to complement the accepted answer, you could also use System.out.read() like this:

class Example {
    public static void main(String args[])
        throws java.io.IOException { // This works! No need to use try{// ...}catch(IOException ex){// ...}         

        System.out.println("Type a letter: ");
        char letter = (char) System.in.read();
        System.out.println("You typed the letter " + letter);
    }
}

If even after repeated upload you still get timeout error, pleasechange your settings in

\phpmyadmin\libraries\config.default.php

from $cfg['ExecTimeLimit'] = 300; to $cfg['ExecTimeLimit'] = 0; and restart. Now there is no execution time limit (trust we are talking about local server).

Good question. I've been using

List<string> myStrings = new List<string>{ "ours", "mine", "yours"};
string joinedString = string.Join(", ", myStrings.ToArray());

It's not LINQ, but it works.

char c1 = (char)97;  //c1 = 'a'

int i = 98;
char c2 = (char)i;  //c2 = 'b'

What does it mean "media that are designed to deal with textual data"?

That those protocols were designed to handle text (often, only English text) instead of binary data (like .png and .jpg images).

They can deal with binary => they can deal with anything.

But the converse is not true. A protocol designed to represent text may improperly treat binary data that happens to contain:

• The bytes 0x0A and 0x0D, used for line endings, which differ by platform.
• Other control characters like 0x00 (NULL = C string terminator), 0x03 (END OF TEXT), 0x04 (END OF TRANSMISSION), or 0x1A (DOS end-of-file) which may prematurely signal the end of data.
• Bytes above 0x7F (if the protocol that was designed for ASCII).
• Byte sequences that are invalid UTF-8.

So you can't just send binary data over a text-based protocol. You're limited to the bytes that represent the non-space non-control ASCII characters, of which there are 94. The reason Base 64 was chosen was that it's faster to work with powers of two, and 64 is the largest one that works.

One question though. How is that systems still don't agree on a common encoding technique like the so common UTF-8?

On the Web, at least, they mostly have. A majority of sites use UTF-8.

The problem in the West is that there is a lot of old software that ass-u-me-s that 1 byte = 1 character and can't work with UTF-8.

The problem in the East is their attachment to encodings like GB2312 and Shift_JIS.

And the fact that Microsoft seems to have still not gotten over having picked the wrong UTF encoding. If you want to use the Windows API or the Microsoft C runtime library, you're limited to UTF-16 or the locale's "ANSI" encoding. This makes it painful to use UTF-8 because you have to convert all the time.

simplest way is to use inspect.isclass as posted in the most-voted answer.
the implementation details could be found at python2 inspect and python3 inspect.
for new-style class: isinstance(object, type)
for old-style class: isinstance(object, types.ClassType)
em, for old-style class, it is using types.ClassType, here is the code from types.py:

class _C:
    def _m(self): pass
ClassType = type(_C)

Comparing test result between Ubuntu Linux and Windows 7.

On Ubuntu

>>> start = time.time(); time.sleep(0.5); (time.time() - start)
0.5005500316619873

On Windows 7

>>> start = time.time(); time.sleep(0.5); (time.time() - start)
0.5

When dealing with passing values from local db to server and vice versa, I was having too much trouble with ?'s and !'s and what not.

So I made a Swift3.0 utility to handle null cases and i can almost totally avoid ?'s and !'s in the code.

func str(_ string: String?) -> String {
    return (string != nil ? string! : "")
}

Ex:-

Before :

    let myDictionary: [String: String] = 
                      ["title": (dbObject?.title != nil ? dbObject?.title! : "")]

After :

    let myDictionary: [String: String] = 
                        ["title": str(dbObject.title)]

and when its required to check for a valid string,

    if !str(dbObject.title).isEmpty {
        //do stuff
    }

This saved me having to go through the trouble of adding and removing numerous ?'s and !'s after writing code that reasonably make sense.

Suppose RetailerProfileModel is your Main class and RetailerPaymentModel is an inner class within it. You can create an object of the Inner class outside the class as follows:

RetailerProfileModel.RetailerPaymentModel paymentModel
        = new RetailerProfileModel().new RetailerPaymentModel();

Make sure:

1. First letter uppercase
2. Class name exact name as file name
3. Make sure your file ends with .php extension

In my case I had 1 and 2 correct but forgot to name my file with .php extension. How I forgot, no idea but it sure gave me a hard time trying to figure out the problem

Some notes to complement the ALTER DATABASE process:

1) You can obtain a full list of databases with logical names and full paths of MDF and LDF files:

   USE master SELECT name, physical_name FROM sys.master_files

2) You can move manually the files with CMD move command:

Move "Source" "Destination"

Example:

md "D:\MSSQLData"
Move "C:\test\SYSADMIT-DB.mdf" "D:\MSSQLData\SYSADMIT-DB_Data.mdf"
Move "C:\test\SYSADMIT-DB_log.ldf" "D:\MSSQLData\SYSADMIT-DB_log.ldf"

3) You should change the default database path for new databases creation. The default path is obtained from the Windows registry.

You can also change with T-SQL, for example, to set default destination to: D:\MSSQLData

USE [master]

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', REG_SZ, N'D:\MSSQLData'

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultLog', REG_SZ, N'D:\MSSQLData'

Just to explain:

2011-02-15 is being interpreted literally as a mathematical operation, to which the answer is 1994.

This, then, is being interpreted as 1994 days since the origin of date (Jan 1st 1900).

1994 days = 5 years, 6 months, 18 days = June 18th 1905

So, if you don't want to to the calculation each time you want compare a date to a particular value use the standard: Compare the value of the toString() function of date object to the string like this :

set @TEST  ='2011-02-05'

Add a notifier in the viewWillAppear function

-(void)viewWillAppear:(BOOL)animated{
  [super viewWillAppear:animated];
  [[NSNotificationCenter defaultCenter] addObserver:self  selector:@selector(orientationChanged:)    name:UIDeviceOrientationDidChangeNotification  object:nil];
}

The orientation change notifies this function

- (void)orientationChanged:(NSNotification *)notification{
   [self adjustViewsForOrientation:[[UIApplication sharedApplication] statusBarOrientation]];
}

which in-turn calls this function where the moviePlayerController frame is orientation is handled

- (void) adjustViewsForOrientation:(UIInterfaceOrientation) orientation {

    switch (orientation)
    {
        case UIInterfaceOrientationPortrait:
        case UIInterfaceOrientationPortraitUpsideDown:
        { 
        //load the portrait view    
        }

            break;
        case UIInterfaceOrientationLandscapeLeft:
        case UIInterfaceOrientationLandscapeRight:
        {
        //load the landscape view 
        }
            break;
        case UIInterfaceOrientationUnknown:break;
    }
}

in viewDidDisappear remove the notification

-(void)viewDidDisappear:(BOOL)animated{
   [super viewDidDisappear:animated];
   [[NSNotificationCenter defaultCenter]removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];
}

I guess this is the fastest u can have changed the view as per orientation

As I can see the code
System.out.println("Managers choice this week" + anyItem + "our recommendation to you");
is unreachable.

Tray to add text with html value to textarea but it wil not works

You need to download the JavaMail API, and put the relevant jar files in your classpath.

Here is javascript I wrote to do just this.

function ImageTile(parentdiv, imagediv) {
imagediv.style.position = 'absolute';

function load(image) {
    //
    // Reset to auto so that when the load happens it resizes to fit our image and that
    // way we can tell what size our image is. If we don't do that then it uses the last used
    // values to auto-size our image and we don't know what the actual size of the image is.
    //
    imagediv.style.height = "auto";
    imagediv.style.width = "auto";
    imagediv.style.top = 0;
    imagediv.style.left = 0;

    imagediv.src = image;
}

//bind load event (need to wait for it to finish loading the image)
imagediv.onload = function() {
    var vpWidth = parentdiv.clientWidth;
    var vpHeight = parentdiv.clientHeight;
    var imgWidth = this.clientWidth;
    var imgHeight = this.clientHeight;

    if (imgHeight > imgWidth) {
        this.style.height = vpHeight + 'px';
        var width = ((imgWidth/imgHeight) * vpHeight);
        this.style.width = width + 'px';
        this.style.left = ((vpWidth - width)/2) + 'px';
    } else {
        this.style.width = vpWidth + 'px';
        var height = ((imgHeight/imgWidth) * vpWidth);
        this.style.height = height + 'px';
        this.style.top = ((vpHeight - height)/2) + 'px';
    }
};

return {
    "load": load
};

}

And to use it just do something like this:

 var tile1 = ImageTile(document.documentElement, document.getElementById("tile1"));
 tile1.load(url);

I use this for a slideshow in which I have two of these "tiles" and I fade one out and the other in. The loading is done on the "tile" that is not visible to avoid the jarring visual affect of the resetting of the style back to "auto".

There are three possible ways to do that.

1. Option

   SELECT  lt.* FROM    table_left lt
   LEFT JOIN
       table_right rt
   ON      rt.value = lt.value
   WHERE   rt.value IS NULL
   

2. Option

   SELECT  lt.* FROM    table_left lt
   WHERE   lt.value NOT IN
   (
   SELECT  value
   FROM    table_right rt
   )
   

3. Option

   SELECT  lt.* FROM    table_left lt
   WHERE   NOT EXISTS
   (
   SELECT  NULL
   FROM    table_right rt
   WHERE   rt.value = lt.value
   )
   

If you are using prototype.js then you can do this:

transport_select.observe('change', function(){
  toggleSelect(transport_select_id)
})

This eliminate (as hope) the problem in cross-browsers

The R Language Definition is handy for answering these types of questions:

• http://cran.r-project.org/doc/manuals/R-lang.html#Indexing

R has three basic indexing operators, with syntax displayed by the following examples

    x[i]
    x[i, j]
    x[[i]]
    x[[i, j]]
    x$a
    x$"a"

For vectors and matrices the [[ forms are rarely used, although they have some slight semantic differences from the [ form (e.g. it drops any names or dimnames attribute, and that partial matching is used for character indices). When indexing multi-dimensional structures with a single index, x[[i]] or x[i] will return the ith sequential element of x.

For lists, one generally uses [[ to select any single element, whereas [ returns a list of the selected elements.

The [[ form allows only a single element to be selected using integer or character indices, whereas [ allows indexing by vectors. Note though that for a list, the index can be a vector and each element of the vector is applied in turn to the list, the selected component, the selected component of that component, and so on. The result is still a single element.

The bash script "corstest" below works for me. It is based on Jun's comment above.

I'm not sure what was your original reason for running Travis locally, if you just wanted to play with it, then stop reading here as it's irrelevant for you.

If you already have experience with hosted Travis and you want to get the same experience in your own datacenter, read on.

Since Dec 2014 Travis CI offers an Enterprise on-premises version.

http://blog.travis-ci.com/2014-12-19-introducing-travis-ci-enterprise/

The pricing is part of the article as well:

The licensing is done per seats, where every license includes 20 users. Pricing starts at $6,000 per license, which includes 20 users and 5 concurrent builds. There's a premium option with unlimited builds for $8,500.

Modules are VB counterparts to C# static classes. When your class is designed solely for helper functions and extension methods and you don't want to allow inheritance and instantiation, you use a Module.

By the way, using Module is not really subjective and it's not deprecated. Indeed you must use a Module when it's appropriate. .NET Framework itself does it many times (System.Linq.Enumerable, for instance). To declare an extension method, it's required to use Modules.

Thank you for this

Here's what I did:

1.Created an Extensions.cs file in a Utils folder.

2.In my model, where state will be abbreviated (e.g. "AL", "NY", etc.):

using System.ComponentModel;
using System.ComponentModel.DataAnnotations;

namespace Web.ProjectName.Models
{
    public class ContactForm
    {

        ...

        [Required]
        [Display(Name = "State")]
        [RegularExpression("[A-Z]{2}")]
        public string State { get; set; }

        ...

    }
}

2.In my view I referenced it:

  @model Web.ProjectName.Models.ContactForm

  ...

  @Html.LabelFor(x => x.State, new { @class = "form-label" })
  @Html.DropDownListFor(x => x.State, Web.ProjectName.Utils.Extensions.GetStatesList(), new { @class = "form-control" })

  ...

iTerm2 - an alternative to Terminal - has an option to use configurable system-wide hotkey to show/hide (initially set to Alt+Space, disabled by default)

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

Best practice is to use an interface to specify the contract and an abstract class as just one implementation thereof. That abstract class can fill in a lot of the boilerplate so you can create an implementation by just overriding what you need to or want to without forcing you to use a particular implementation.

You can use HTTP Toolkit to do exactly this.

It's especially useful if you need to do this quickly, with no code changes: you can open a terminal from HTTP Toolkit, run any Python code from there as normal, and you'll be able to see the full content of every HTTP/HTTPS request immediately.

There's a free version that can do everything you need, and it's 100% open source.

I'm the creator of HTTP Toolkit; I actually built it myself to solve the exact same problem for me a while back! I too was trying to debug a payment integration, but their SDK didn't work, I couldn't tell why, and I needed to know what was actually going on to properly fix it. It's very frustrating, but being able to see the raw traffic really helps.

On the "Scripts" tab, go to where your code is. At the left of the line number, click. This will set a breakpoint.

Screenshot:

You will then be able to track your breakpoints within the right tab (as shown in the screenshot).

Set to true android:layout_alignParentTop="true" and android:layout_centerHorizontal="true" in the Button, like this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
     <Button
        android:id="@+id/switch_flashlight"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/turn_on_flashlight"
        android:textColor="@android:color/black"
        android:onClick="action_trn"
        android:background="@android:color/holo_green_light"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:padding="5dp" />
</RelativeLayout>

You can do the following:

TimeSpan duration = b - a;

There's plenty of built in methods in the timespan class to do what you need, i.e.

duration.TotalSeconds
duration.TotalMinutes

More info can be found here.

The fundamental issue with your code is that you mix two APIs. Unfortunately online resources are not great at pointing this out, but there are two semaphore APIs on UNIX-like systems:

• POSIX IPC API, which is a standard API
• System V API, which is coming from the old Unix world, but practically available almost all Unix systems

Looking at the code above you used semget() from the System V API and tried to post through sem_post() which comes from the POSIX API. It is not possible to mix them.

To decide which semaphore API you want you don't have so many great resources. The simple best is the "Unix Network Programming" by Stevens. The section that you probably interested in is in Vol #2.

These two APIs are surprisingly different. Both support the textbook style semaphores but there are a few good and bad points in the System V API worth mentioning:

• it builds on semaphore sets, so once you created an object with semget() that is a set of semaphores rather then a single one
• the System V API allows you to do atomic operations on these sets. so you can modify or wait for multiple semaphores in a set
• the SysV API allows you to wait for a semaphore to reach a threshold rather than only being non-zero. waiting for a non-zero threshold is also supported, but my previous sentence implies that
• the semaphore resources are pretty limited on every unixes. you can check these with the 'ipcs' command
• there is an undo feature of the System V semaphores, so you can make sure that abnormal program termination doesn't leave your semaphores in an undesired state

This is the shared preferences code i use successfully, Refer this link:

  public class MainActivity extends Activity {

private static final int RESULT_SETTINGS = 1;
Button button;
public String a="dd";

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

 button = (Button) findViewById(R.id.btnoptions);


setContentView(R.layout.activity_main);

  // showUserSettings();
  }

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.settings, menu);
return true;
 }

@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {

case R.id.menu_settings:
 Intent i = new Intent(this, UserSettingActivity.class);
 startActivityForResult(i, RESULT_SETTINGS);
 break;

 }

return true;
}

@Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data)     {
  super.onActivityResult(requestCode, resultCode, data);

 switch (requestCode) {
 case RESULT_SETTINGS:
 showUserSettings();
 break;

 } 

  }

  private void showUserSettings() {
 SharedPreferences sharedPrefs = PreferenceManager
.getDefaultSharedPreferences(this);

 StringBuilder builder = new StringBuilder();

 builder.append("\n Pet: "
  + sharedPrefs.getString("prefpetname", "NULL"));

 builder.append("\n Address:"
 + sharedPrefs.getString("prefaddress","NULL" ));

 builder.append("\n Your name: "
 + sharedPrefs.getString("prefname", "NULL"));

 TextView settingsTextView = (TextView) findViewById(R.id.textUserSettings);


  settingsTextView.setText(builder.toString());


    }

   }

HAPPY CODING!

Redgate's SQL Search is a great tool for doing this, it's a free plugin for SSMS.

You can use shell in-build variable PWD, like this:

export PATH=$PATH:$PWD+somethingelse

Tried and tested. I know that this works:

Replace(EmailText, vbNewLine, "<br>")

i.e. vbNewLine is also the equivalent of \n

You could try mixing Number() and toFixed().

Have your target number converted to a nice string with X digits then convert the formated string to a number.

Number( (myVar).toFixed(2) )

See example below:

var myNumber = 5.01;_x000D_
var multiplier = 5;_x000D_
$('#actionButton').on('click', function() {_x000D_
  $('#message').text( myNumber * multiplier );_x000D_
});_x000D_
_x000D_
$('#actionButton2').on('click', function() {_x000D_
  $('#message').text( Number( (myNumber * multiplier).toFixed(2) ) );_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>_x000D_
<button id="actionButton">Weird numbers</button>_x000D_
<button id="actionButton2">Nice numbers</button>_x000D_
_x000D_
<div id="message"></div>

application/xml is seen by svn as binary type whereas text/xml as text file for which a diff can be displayed.

This will toggle the Nav menu when you click on/off the element.

$(document).on('click', function(e) {
    var elem = $(e.target).closest('#menu'),
    box = $(e.target).closest('#nav');
 if (elem.length) {
    e.preventDefault();
    $('#nav').toggle();
  } else if (!box.length) {
    $('#nav').hide();
 }
});



<li id="menu"><a></a></li>
<ul id="nav" >  //Nav will toggle when you Click on Menu(it can be an icon in this example)
        <li class="page"><a>Page1</a></li>
        <li class="page"><a>Pag2</a></li>
        <li class="page"><a>Page3</a></li>            
        <li class="page"><a>Page4</a></li>
</ul>

Config is written to .npmrc files so just delete it. NPM looks up config in this order, setting in the next overwrites the previous one. So make sure there might be global config that usually is overwritten in per-project that becomes active after you have deleted the per-project config file. npm config list will allways list the active config.

1. npm builtin config file (/path/to/npm/npmrc)
2. global config file ($PREFIX/etc/npmrc)
3. per-user config file ($HOME/.npmrc)
4. per-project config file (/path/to/my/project/.npmrc)

the implementation in the cpp file should be in the form

gameObject::gameObject()
    {
    x = 0;
    y = 0;
    }
gameObject::gameObject(int inx, int iny)
    {
        x = inx;
        y = iny;
    }

gameObject::~gameObject()
    {
    //
    }
int gameObject::add()
    {
        return x+y;
    }

not within a class gameObject { } definition block

You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.

You will then do e.g.:

wget www.google.com

I had the same problem and I solved by using the postcast server. You can install it locally and use it.

I think the error is caused by the redundant ,

flutter:
  uses-material-design: true, # <<< redundant , at the end of the line
  assets:
    - images/lake.jpg

I'd also suggest to create an assets folder in the directory that contains the pubspec.yaml file and move images there and use

flutter:
  uses-material-design: true
  assets:
    - assets/images/lake.jpg

The assets directory will get some additional IDE support that you won't have if you put assets somewhere else.

It became a popular question and I got a notification. I am sorry, I forgot to answer before which I should have done. I solved it long back.

Run it in a batch file and you should get what you are looking for.

1. go to : your adb folder \sdk\platform-tools\
2. type cmd
3. type : adb remount on command window
4. adb shell
5. su
6. rm /system/app/YourApp.apk
7. Restart your device

OK.. We needed to compare a dynamic number of product names...

There's probably a better way... but this works for me...

... because....Strings are just Arrays of characters.... :>}

//  Compare Strings ...  Return Matching Text and Differences with Product IDs...

//  From MySql...
$productID1 = 'abc123';
$productName1 = "EcoPlus Premio Jet 600";   

$productID2 = 'xyz789';
$productName2 = "EcoPlus Premio Jet 800";   

$ProductNames = array(
    $productID1 => $productName1,
    $productID2 => $productName2
);


function compareNames($ProductNames){   

    //  Convert NameStrings to Arrays...    
    foreach($ProductNames as $id => $product_name){
        $Package1[$id] = explode(" ",$product_name);    
    }

    // Get Matching Text...
    $Matching = call_user_func_array('array_intersect', $Package1 );
    $MatchingText = implode(" ",$Matching);

    //  Get Different Text...
    foreach($Package1 as $id => $product_name_chunks){
        $Package2 = array($product_name_chunks,$Matching);
        $diff = call_user_func_array('array_diff', $Package2 );
        $DifferentText[$id] = trim(implode(" ", $diff));
    }

    $results[$MatchingText]  = $DifferentText;              
    return $results;    
}

$Results =  compareNames($ProductNames);

print_r($Results);

// Gives us this...
[EcoPlus Premio Jet] 
        [abc123] => 600
        [xyz789] => 800

1. Entities are managed by javax.persistence.EntityManager instance using persistence context.
2. Each EntityManager instance is associated with a persistence context.
3. Within the persistence context, the entity instances and their lifecycle are managed.
4. Persistence context defines a scope under which particular entity instances are created, persisted, and removed.
5. A persistence context is like a cache which contains a set of persistent entities , So once the transaction is finished, all persistent objects are detached from the EntityManager's persistence context and are no longer managed.

Probably the most definitive is Figure B.1(d) of the ggplot2 book, the appendices of which are available at http://ggplot2.org/book/appendices.pdf.

However, it is not quite that simple. hjust and vjust as described there are how it works in geom_text and theme_text (sometimes). One way to think of it is to think of a box around the text, and where the reference point is in relation to that box, in units relative to the size of the box (and thus different for texts of different size). An hjust of 0.5 and a vjust of 0.5 center the box on the reference point. Reducing hjust moves the box right by an amount of the box width times 0.5-hjust. Thus when hjust=0, the left edge of the box is at the reference point. Increasing hjust moves the box left by an amount of the box width times hjust-0.5. When hjust=1, the box is moved half a box width left from centered, which puts the right edge on the reference point. If hjust=2, the right edge of the box is a box width left of the reference point (center is 2-0.5=1.5 box widths left of the reference point. For vertical, less is up and more is down. This is effectively what that Figure B.1(d) says, but it extrapolates beyond [0,1].

But, sometimes this doesn't work. For example

DF <- data.frame(x=c("a","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p + opts(axis.text.x=theme_text(vjust=0))
p + opts(axis.text.x=theme_text(vjust=1))
p + opts(axis.text.x=theme_text(vjust=2))

The three latter plots are identical. I don't know why that is. Also, if text is rotated, then it is more complicated. Consider

p + opts(axis.text.x=theme_text(hjust=0, angle=90))
p + opts(axis.text.x=theme_text(hjust=0.5 angle=90))
p + opts(axis.text.x=theme_text(hjust=1, angle=90))
p + opts(axis.text.x=theme_text(hjust=2, angle=90))

The first has the labels left justified (against the bottom), the second has them centered in some box so their centers line up, and the third has them right justified (so their right sides line up next to the axis). The last one, well, I can't explain in a coherent way. It has something to do with the size of the text, the size of the widest text, and I'm not sure what else.

You could use the maven dependency plugin which has a nice dependency:get goal since version 2.1. No need for a pom, everything happens on the command line.

To make sure to find the dependency:get goal, you need to explicitly tell maven to use the version 2.1, i.e. you need to use the fully qualified name of the plugin, including the version:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=url \
    -Dartifact=groupId:artifactId:version

UPDATE: With older versions of Maven (prior to 2.1), it is possible to run dependency:get normally (without using the fully qualified name and version) by forcing your copy of maven to use a given version of a plugin.

This can be done as follows:

1. Add the following line within the <settings> element of your ~/.m2/settings.xml file:

<usePluginRegistry>true</usePluginRegistry>

2. Add the file ~/.m2/plugin-registry.xml with the following contents:

<?xml version="1.0" encoding="UTF-8"?>
<pluginRegistry xsi:schemaLocation="http://maven.apache.org/PLUGIN_REGISTRY/1.0.0 http://maven.apache.org/xsd/plugin-registry-1.0.0.xsd"
xmlns="http://maven.apache.org/PLUGIN_REGISTRY/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-dependency-plugin</artifactId>
      <useVersion>2.1</useVersion>
      <rejectedVersions/>
    </plugin>
  </plugins>
</pluginRegistry>

But this doesn't seem to work anymore with maven 2.1/2.2. Actually, according to the Introduction to the Plugin Registry, features of the plugin-registry.xml have been redesigned (for portability) and the plugin registry is currently in a semi-dormant state within Maven 2. So I think we have to use the long name for now (when using the plugin without a pom, which is the idea behind dependency:get).

Use position:fixed; and set the top:0;left:0;right:0;height:100px; and you should be able to have it "stick" to the top of the page.

<div style="position:fixed;top:0;left:0;right:0;height:100px;">Some buttons</div>

You should set layout first by syntax pnlButton.setLayout(), and then choose the most suitable layout which u want. Ex: pnlButton.setLayout(new FlowLayout(FlowLayout.LEADING, 5, 5));. And then, take that JButton into JPanel.

THIS WORKS FOR DUPLICATING ONE ROW ONLY

• Select your ONE row from your table
• Fetch all associative
• unset the ID row (Unique Index key)
• Implode the array[0] keys into the column names
• Implode the array[0] values into the column values
• Run the query

The code:

 $qrystr = "SELECT * FROM mytablename  WHERE id= " . $rowid;
 $qryresult = $this->connection->query($qrystr);
 $result = $qryresult->fetchAll(PDO::FETCH_ASSOC);
 unset($result[0]['id']); //Remove ID from array
 $qrystr = " INSERT INTO mytablename";
 $qrystr .= " ( " .implode(", ",array_keys($result[0])).") ";
 $qrystr .= " VALUES ('".implode("', '",array_values($result[0])). "')";
 $result = $this->connection->query($qrystr);
 return $result;

Of course you should use PDO:bindparam and check your variables against attack, etc but gives the example

additional info

If you have a problem with handling NULL values, you can use following codes so that imploding names and values only for whose value is not NULL.

foreach ($result[0] as $index => $value) {
    if ($value === null) unset($result[0][$index]);
}

Another 2 very usefull shortcuts are to move lines selected up and down, like sublime text does...

{
  "key" : "ctrl+shift+down", "command" : "editor.action.moveLinesDownAction",
  "when" : "editorTextFocus && !editorReadonly"
},

and

{
  "key" : "ctrl+shift+up", "command" : "editor.action.moveLinesUpAction",
  "when" : "editorTextFocus && !editorReadonly"
}

sample = ("Python 3.2 is very easy") #sample string  
letters = 0  # initiating the count of letters to 0
numeric = 0  # initiating the count of numbers to 0

        for i in sample:  
            if i.isdigit():      
                numeric +=1      
            elif i.isalpha():    
                letters +=1    
            else:    
               pass  
letters  
numeric  

Simply use this query, I have tried it as per my scenario and it works well

ALTER TABLE katalog ADD FOREIGN KEY (`Sprache`) REFERENCES Sprache(`ID`);

No additional view is required. https://docs.djangoproject.com/en/3.0/ref/views/

Just put the error files in the root of templates directory

• 404.html
• 400.html
• 403.html
• 500.html

And it should use your error page when debug is False

I strongly recommend you learn how to use layout managers to get the layout you want to see. null layouts are fragile, and cause no end of trouble.

You need the following:

pictbox.Image = null;
pictbox.update();

Here what I understood from the question is starting with "a " and then "b" ex:

• abhay
• abhishek
• abhinav

So there should be two conditions and both should be true means you cant use "OR" operator Ordered by is not not compulsory but its good if you use.

Select e_name from emp 
where  e_name like 'a%' AND e_name like '_b%'
Ordered by e_name

If you're using Selenium with Firefox you should be able to use EXSLT extensions, and regexp:test()

Does this work for you?

String expr = "//*[regexp:test(@id, 'sometext[0-9]+_text')]";
driver.findElement(By.xpath(expr));

$.browser.chrome = /chrom(e|ium)/.test(navigator.userAgent.toLowerCase()); 

if($.browser.chrome){
  alert(1);      
}

UPDATE:(10x to @Mr. Bacciagalupe)

jQuery has removed $.browser from 1.9 and their latest release.

But you can still use $.browser as a standalone plugin, found here

A Union is different from a struct as a Union repeats over the others: it redefines the same memory whilst the struct defines one after the other with no overlaps or redefinitions.

I think a very simple way would be to use the Counter class. You can then use the most_common() function of the Counter instance as mentioned here.

For 1-d arrays:

import numpy as np
from collections import Counter

nparr = np.arange(10) 
nparr[2] = 6 
nparr[3] = 6 #6 is now the mode
mode = Counter(nparr).most_common(1)
# mode will be [(6,3)] to give the count of the most occurring value, so ->
print(mode[0][0])    

For multiple dimensional arrays (little difference):

import numpy as np
from collections import Counter

nparr = np.arange(10) 
nparr[2] = 6 
nparr[3] = 6 
nparr = nparr.reshape((10,2,5))     #same thing but we add this to reshape into ndarray
mode = Counter(nparr.flatten()).most_common(1)  # just use .flatten() method

# mode will be [(6,3)] to give the count of the most occurring value, so ->
print(mode[0][0])

This may or may not be an efficient implementation, but it is convenient.

You have to run a web server (e.g. Apache) and browse to your localhost, mostly likely on port 80.

What you really ought to do is install an all-in-one package like XAMPP, it bundles Apache, MySQL PHP, and Perl (if you were so inclined) as well as a few other tools that work with Apache and MySQL - plus it's cross platform (that's what the 'X' in 'XAMPP' stands for).

Once you install XAMPP (and there is an installer, so it shouldn't be hard) open up the control panel for XAMPP and then click the "Start" button next to Apache - note that on applications that require a database, you'll also need to start MySQL (and you'll be able to interface with it through phpMyAdmin). Once you've started Apache, you can browse to http://localhost.

Again, regardless of whether or not you choose XAMPP (which I would recommend), you should just have to start Apache.

@JSideris, sample code for getting insertedId.

db.collection(COLLECTION).insertOne(data, (err, result) => {
    if (err) 
      return err;
    else 
      return result.insertedId;
  });

I assume your game has a main loop, and all your sprites are in a list called sprites.

In your main loop, get all events, and check for the MOUSEBUTTONDOWN or MOUSEBUTTONUP event.

while ... # your main loop
  # get all events
  ev = pygame.event.get()

  # proceed events
  for event in ev:

    # handle MOUSEBUTTONUP
    if event.type == pygame.MOUSEBUTTONUP:
      pos = pygame.mouse.get_pos()

      # get a list of all sprites that are under the mouse cursor
      clicked_sprites = [s for s in sprites if s.rect.collidepoint(pos)]
      # do something with the clicked sprites...

So basically you have to check for a click on a sprite yourself every iteration of the mainloop. You'll want to use mouse.get_pos() and rect.collidepoint().

Pygame does not offer event driven programming, as e.g. cocos2d does.

Another way would be to check the position of the mouse cursor and the state of the pressed buttons, but this approach has some issues.

if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()):
  print ("You have opened a chest!")

You'll have to introduce some kind of flag if you handled this case, since otherwise this code will print "You have opened a chest!" every iteration of the main loop.

handled = False

while ... // your loop

  if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()) and not handled:
    print ("You have opened a chest!")
    handled = pygame.mouse.get_pressed()[0]

Of course you can subclass Sprite and add a method called is_clicked like this:

class MySprite(Sprite):
  ...

  def is_clicked(self):
    return pygame.mouse.get_pressed()[0] and self.rect.collidepoint(pygame.mouse.get_pos())

So, it's better to use the first approach IMHO.

When the return type is void, your method doesn't return anything.

Look again at your code: There's no return in that method. You print to the console and exit.

import groovyx.net.http.HTTPBuilder;

public class HttpclassgetrRoles {
     static void main(String[] args){
         def baseUrl = new URL('http://test.city.com/api/Cirtxyz/GetUser')

         HttpURLConnection connection = (HttpURLConnection) baseUrl.openConnection();
         connection.addRequestProperty("Accept", "application/json")
         connection.with {
           doOutput = true
           requestMethod = 'GET'
           println content.text
         }

     }
}

The short version is that you cannot use variable-width patterns in lookbehinds using Python's re module. There is no way to change this:

>>> import re
>>> re.sub("(?<=foo)bar(?=baz)", "quux", "foobarbaz")
'fooquuxbaz'
>>> re.sub("(?<=fo+)bar(?=baz)", "quux", "foobarbaz")

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    re.sub("(?<=fo+)bar(?=baz)", "quux", string)
  File "C:\Development\Python25\lib\re.py", line 150, in sub
    return _compile(pattern, 0).sub(repl, string, count)
  File "C:\Development\Python25\lib\re.py", line 241, in _compile
    raise error, v # invalid expression
error: look-behind requires fixed-width pattern

This means that you'll need to work around it, the simplest solution being very similar to what you're doing now:

>>> re.sub("(fo+)bar(?=baz)", "\\1quux", "foobarbaz")
'fooquuxbaz'
>>>
>>> # If you need to turn this into a callable function:
>>> def replace(start, replace, end, replacement, search):
        return re.sub("(" + re.escape(start) + ")" + re.escape(replace) + "(?=" + re.escape + ")", "\\1" + re.escape(replacement), search)

This doesn't have the elegance of the lookbehind solution, but it's still a very clear, straightforward one-liner. And if you look at what an expert has to say on the matter (he's talking about JavaScript, which lacks lookbehinds entirely, but many of the principles are the same), you'll see that his simplest solution looks a lot like this one.

Kind of like @AymKdn's answer, but this will allow you to change the options without re-initializing the modal.

$('#myModal').data('modal').options.keyboard = false;

Or if you need to do multiple options, JavaScript's with comes in handy here!

with ($('#myModal').data("modal").options) {
    backdrop = 'static';
    keyboard = false;
}

If the modal is already open, these options will only take effect the next time the modal is opened.

$( this ).find( 'li.target' ).css("border", "3px double red");

or

$( this ).children( 'li.target' ).css("border", "3px double red");

Use children for immediate descendants, or find for deeper elements.

Don't use quotes with <<EOF:

EOF

Variable expansion is the default behavior inside of here-docs. You disable that behavior by quoting the label (with single or double quotes).

You can use pyautogui or pymsgbox:

import pyautogui
pyautogui.alert("This is a message box",title="Hello World")

Using pymsgbox is the same as using pyautogui:

import pymsgbox
pymsgbox.alert("This is a message box",title="Hello World")

For start you can use:

<body style="margin:0;padding:0">

Once you study a bit about css, you can change it to:

body {margin:0;padding:0}

in your stylesheet.

I had this issue, I logged in as administrator and it fixed the issue.

Here is how I implemented the encoding. I took inspiration from the answers given above.

function encodeHTML(str) {
  const code = {
      ' ' : ' ',
      '¢' : '¢',
      '£' : '£',
      '¥' : '¥',
      '€' : '€', 
      '©' : '©',
      '®' : '®',
      '<' : '&lt;', 
      '>' : '&gt;',  
      '"' : '&quot;', 
      '&' : '&amp;',
      '\'' : '&apos;'
  };
  return str.replace(/[\u00A0-\u9999<>\&''""]/gm, (i)=>code[i]);
}

// TEST
console.log(encodeHTML("Dolce & Gabbana"));
console.log(encodeHTML("Hamburgers < Pizza < Tacos"));
console.log(encodeHTML("Sixty > twelve"));
console.log(encodeHTML('Stuff in "quotation marks"'));
console.log(encodeHTML("Schindler's List"));
console.log(encodeHTML("<>"));

In HTML the values of attributes eventually become strings. To mitigate that in undesired situations you can have a function to conditionally parse them into values they represent in the JavaScript or any other programming langauge of interest.

Following is an explanation to do it for reviving boolean type from the string type, but it can be further expanded into other data types too, like numbers, arrays or objects.

In addition to that JSON.parse has a revive parameter which is a function. It also can be used to achieve the same.

Let's call a string looking like a boolean, "true", a boolean string likewise we can call a string like a number, "1", a number string. Then we can determine if a string is a boolean string:

const isBooleanString = (string) => ['true', 'false'].some(item => item === string);

After that we need to parse the boolean string as JSON by JSON.parse method:

JSON.parse(aBooleanString);

However, any string that is not a boolean string, number string, or any stringified object or array (any invalid JSON) will cause the JSON.parse method to throw a SyntaxError.

So, you will need to know with what to call it, i.e. if it is a boolean string. You can achieve this by writing a function that makes the above defiend boolean string check and call JSON.parse:

function parse(string){
  return isBooleanString(string) ? JSON.parse(string)
    : string;
}

One can further generalize the isBooleanString utility to have a more broader perspective on what qualifies as a boolean string by further parametrizing it to accept an optional array of accepted boolean strings:

const isBooleanString = (string, spec = ['true', 'false', 'True', 'False']) => spec.some(item => item === string);

Why use a <a href>? I solve it like this:

<span class='a'>fake link</span>

And style it with:

.a {text-decoration:underline; cursor:pointer;}

You can easily access it with jQuery:

$(".a").click();

Ahah! Checkout the previous commit, then checkout the master.

git checkout HEAD^
git checkout -f master

This "functional approach" abstraction leaks big time. Nothing on the language level prevents side effects. As long as you can make it call your lambda/delegate for every element in the container - you will get the "ForEach" behavior.

Here for example one way of merging srcDictionary into destDictionary (if key already exists - overwrites)

this is a hack, and should not be used in any production code.

var b = srcDictionary.Select(
                             x=>
                                {
                                  destDictionary[x.Key] = x.Value;
                                  return true;
                                }
                             ).Count();

I am using python 3 in windows. I also faced this issue. I just uninstalled 'mysqlclient' and then installed it again. It worked somehow

There is now a an approach to do this, using Doctrine's Criteria.

A full example can be seen in How to use a findBy method with comparative criteria, but a brief answer follows.

use \Doctrine\Common\Collections\Criteria;

// Add a not equals parameter to your criteria
$criteria = new Criteria();
$criteria->where(Criteria::expr()->neq('prize', 200));

// Find all from the repository matching your criteria
$result = $entityRepository->matching($criteria);

HTTP 1.1 is the latest version of Hypertext Transfer Protocol, the World Wide Web application protocol that runs on top of the Internet's TCP/IP suite of protocols. compare to HTTP 1.0 , HTTP 1.1 provides faster delivery of Web pages than the original HTTP and reduces Web traffic.

Web traffic Example: For example, if you are accessing a server. At the same time so many users are accessing the server for the data, Then there is a chance for hanging the Server. This is Web traffic.

If you want to update any specific version from the package.json you can update the version of the package by doing ==>

yarn add package-name@version-number

or

npm install --save package-name@version-number

If you want to update all packages to the latest version you can run command ==>

npm audit fix --force

fenomas's answer was really good...it got me off of looking into the HTML code. I know that jb was looking for something that works in Captivate, but the question is broad enough to include people working out of Flash (I'm using CS5), so I thought I'd throw in the specific answer to my situation here.

If you're using the stock Adobe FLVPlayback component in Flash (you probably are if you used File > Import > Import Video...), there's an option in the Properties panel, under Component Parameters. Look for 'autoPlay' and uncheck it. That'll stop autoplay when the page loads!

Most answers here are pretty old.

In the past when un managed nand was the most popular storage technology, yaffs2 was the most common file system. This days there are few devices using un-managed nand, and those still in use are slowly migrating to ubifs.

Today most common storage is emmc (managed nand), for such devices ext4 is far more popular, but, this file system is slowly clears its way for f2fs (flash friendly fs).

Edit: f2fs will probably won't make it as the common fs for flash devices (including android)

Not really what you need, but it can help and answser the question here depending of what you want to achieve.

You can prevent all pointer events to be sent to the input by using the CSS property : pointer-events:none It will kind of add a layer on top of the element that will prevent you to click in it ... You can also add a cursor:text to the parent element to give back the text cursor style to the input ...

Usefull, for example, when you can't modify the JS/HTML of a module.. and you can just customize it by css.

JSFIDDLE

To be short, use:

write-output "your text" | out-file -append -encoding utf8 "filename"

Hey now you can give to body background image

and set the background-position:center center;

as like this

body{
background:url('../img/some.jpg') no-repeat center center;
min-height:100%;
}

Update your .babelrc file according to the following examples, it will work.

If you are using @babel/preset-env package

{
  "presets": [
    [
      "@babel/preset-env", {
        "targets": {
          "node": "current"
        }
      }
    ]
  ]
}
or if you are using babel-preset-env package

{
  "presets": [
    [
      "env", {
        "targets": {
          "node": "current"
        }
      }
    ]
  ]
}

TL;DR:

The ActionListeners (there can be multiple) execute in the order they were registered BEFORE the action

Long Answer:

A business action typically invokes an EJB service and if necessary also sets the final result and/or navigates to a different view if that is not what you are doing an actionListener is more appropriate i.e. for when the user interacts with the components, such as h:commandButton or h:link they can be handled by passing the name of the managed bean method in actionListener attribute of a UI Component or to implement an ActionListener interface and pass the implementation class name to actionListener attribute of a UI Component.

Another option to tag a Subversion repository is to add the tag to the svn:log property like this:

   echo "TAG: your_tag_text" > newlog
   svn propget $REPO --revprop -r $tagged_revision >> newlog
   svn propset $REPO --revprop -r $tagged_revision -F newlog
   rm newlog

I recently started thinking that this is the most "right" way to tag. This way you don't create extra revisions (as you do with "svn cp") and still can easily extract all tags by using grep on "svn log" output:

   svn log | awk '/----/ {
                      expect_rev=1;
                      expect_tag=0;
                  }
                  /^r[[:digit:]]+/ {
                      if(expect_rev) {
                          rev=$1;
                          expect_tag=1;
                          expect_rev=0;
                      }
                  }
                  /^TAG:/ {
                      if(expect_tag) {
                          print "Revision "rev", Tag: "$2;
                      }
                      expect_tag=0;
                  }'

Also, this way you may seamlessly delete tags if you need to. So the tags become a complete meta-information, and I like it.

In the System.Windows.Forms class, you can find more on the MSDN page for this here. Among other things you can control the message box text, title, default button, and icons. Since you didn't specify, if you are trying to do this in a webpage you should look at triggering the javascript alert("my message"); or confirm("my question"); functions.

You can use the following code to check if the file can be opened with exclusive access (that is, it is not opened by another application). If the file isn't closed, you could wait a few moments and check again until the file is closed and you can safely copy it.

You should still check if File.Copy fails, because another application may open the file between the moment you check the file and the moment you copy it.

public static bool IsFileClosed(string filename)
{
    try
    {
        using (var inputStream = File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.None))
        {
            return true;
        }
    }
    catch (IOException)
    {
        return false;
    }
}

Try using java.util.TreeSet that implements SortedSet.

To quote the doc:

"The elements are ordered using their natural ordering, or by a Comparator provided at set creation time, depending on which constructor is used"

Note that add, remove and contains has a time cost log(n).

If you want to access the content of the set as an Array, you can convert it doing:

YourType[] array = someSet.toArray(new YourType[yourSet.size()]); 

This array will be sorted with the same criteria as the TreeSet (natural or by a comparator), and in many cases this will have a advantage instead of doing a Arrays.sort()

The trick to this is specifying 100% height on the html and body elements. Some browsers look to the parent elements (html, body) to calculate the height.

<html>
    <body>
        <div id="Header">
        </div>

You can try this with Color.FromArgb:

Random rnd = new Random();
lbl.ForeColor = Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255));

The easiest solution working fine for me is this:

export CFLAGS=-ggdb
export CXXFLAGS=-ggdb

CMake will append them to all configurations' flags. Just make sure to clear CMake cache.

Here is an example for shared memory :

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>

#define SHM_SIZE 1024  /* make it a 1K shared memory segment */

int main(int argc, char *argv[])
{
    key_t key;
    int shmid;
    char *data;
    int mode;

    if (argc > 2) {
        fprintf(stderr, "usage: shmdemo [data_to_write]\n");
        exit(1);
    }

    /* make the key: */
    if ((key = ftok("hello.txt", 'R')) == -1) /*Here the file must exist */ 
{
        perror("ftok");
        exit(1);
    }

    /*  create the segment: */
    if ((shmid = shmget(key, SHM_SIZE, 0644 | IPC_CREAT)) == -1) {
        perror("shmget");
        exit(1);
    }

    /* attach to the segment to get a pointer to it: */
    data = shmat(shmid, NULL, 0);
    if (data == (char *)(-1)) {
        perror("shmat");
        exit(1);
    }

    /* read or modify the segment, based on the command line: */
    if (argc == 2) {
        printf("writing to segment: \"%s\"\n", argv[1]);
        strncpy(data, argv[1], SHM_SIZE);
    } else
        printf("segment contains: \"%s\"\n", data);

    /* detach from the segment: */
    if (shmdt(data) == -1) {
        perror("shmdt");
        exit(1);
    }

    return 0;
}

Steps :

1. Use ftok to convert a pathname and a project identifier to a System V IPC key

2. Use shmget which allocates a shared memory segment

3. Use shmat to attache the shared memory segment identified by shmid to the address space of the calling process

4. Do the operations on the memory area

5. Detach using shmdt

Using Typescript 3.6.3, and Angular 6, none of these solutions worked for me.

What did work was to follow the tutorial here which says you need to add a small file called njson-typings.d.ts to your project, containing this:

declare module "*.json" {
  const value: any;
  export default value;
}

Once this was done, I could simply import my hardcoded json data:

import employeeData from '../../assets/employees.json';

and use it in my component:

export class FetchDataComponent implements OnInit {
  public employees: Employee[];

  constructor() {
    //  Load the data from a hardcoded .json file
    this.employees = employeeData;
    . . . .
  }

And for those of you using an anonymous expression:

await Task.Run(async () =>
{
   SQLLiteUtils slu = new SQLiteUtils();
   await slu.DeleteGroupAsync(groupname);
});

If you have url with path variables, example www.myexampl.com/item/12/update where 12 is the id and create is the variable you want to use for specifying your execution for instance in using a single form to do an update and create, you do this in your controller.

   @PostMapping(value = "/item/{id}/{method}")
    public String getForm(@PathVariable("id") String itemId ,  
        @PathVariable("method") String methodCall , Model model){

     if(methodCall.equals("create")){
            //logic
      }
     if(methodCall.equals("update")){
            //logic
      }

      return "path to your form";
    }

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.

All JSON.parse implementations most likely use eval()

JSON.parse is based on Douglas Crockford's solution, which uses eval() right there on line 497.

// In the third stage we use the eval function to compile the text into a
// JavaScript structure. The '{' operator is subject to a syntactic ambiguity
// in JavaScript: it can begin a block or an object literal. We wrap the text
// in parens to eliminate the ambiguity.

j = eval('(' + text + ')');

The advantage of JSON.parse is that it verifies the argument is correct JSON syntax.

@BBKim pretty much gave the best answer, but it can just be done shorter. I'm surprised noone came up with it yet.

dat <- data.frame(x = rnorm(10, 30, .2), y = runif(10, 3, 5)) dat <- apply(dat, 2, function(x) (x - mean(x)) / sd(x))

page-break-inside: avoid; gave me trouble using wkhtmltopdf.

To avoid breaks in the text add display: table; to the CSS of the text-containing div.

I hope this works for you too. Thanks JohnS.

From your question it seems like you are using C99, as you have used %lf for double.

To achieve the desired output replace:

sprintf(aa, "%lf", a);

with

sprintf(aa, "%0.7f", a);

The general syntax "%A.B" means to use B digits after decimal point. The meaning of the A is more complicated, but can be read about here.

When you apply your own function, there is not automatic exclusions of non-numeric columns. This is slower, though, than the application of .sum() to the groupby

In [8]: df.groupby('A').apply(lambda x: x.sum())

Doing this on a whole frame, one group at a time. Key is to return a Series

def f(x):
     return Series(dict(A = x['A'].sum(), 
                        B = x['B'].sum(),

In my case, I was using the Docker method for the AWS CLI tool, and I hadn't read the instructions far enough to realize that I had to make my credentials directory visible to the docker container. https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-docker.html

Instead of

docker run --rm -it amazon/aws-cli:latest command args...

I needed to do:

docker run --rm -it -v ~/.aws:/root/.aws amazon/aws-cli:latest command args...

I'm glad that worked out, so I guess you had to explicitly set 'auto' on IE6 in order for it to mimic other browsers!

I actually recently found another technique for scaling images, again designed for backgrounds. This technique has some interesting features:

1. The image aspect ratio is preserved
2. The image's original size is maintained (that is, it can never shrink only grow)

The markup relies on a wrapper element:

<div id="wrap"><img src="test.png" /></div>

Given the above markup you then use these rules:

#wrap {
  height: 100px;
  width: 100px;
}
#wrap img {
  min-height: 100%;
  min-width: 100%;
}

If you then control the size of wrapper you get the interesting scale effects that I list above.

To be explicit, consider the following base state: A container that is 100x100 and an image that is 10x10. The result is a scaled image of 100x100.

1. Starting at the base state, the container resized to 20x100, the image stays resized at 100x100.
2. Starting at the base state, the image is changed to 10x20, the image resizes to 100x200.

So, in other words, the image is always at least as big as the container, but will scale beyond it to maintain it's aspect ratio.

This probably isn't useful for your site, and it doesn't work in IE6. But, it is useful to get a scaled background for your view port or container.

Most simplest way is to use a IF(). Yes Mysql allows you to do conditional logic. IF function takes 3 params CONDITION, TRUE OUTCOME, FALSE OUTCOME.

So Logic is

if report.type = 'p' 
    amount = amount 
else 
    amount = -1*amount 

SQL

SELECT 
    id, IF(report.type = 'P', abs(amount), -1*abs(amount)) as amount
FROM  report

You may skip abs() if all no's are +ve only

Each column has like() method, which can be used in query.filter(). Given a search string, add a % character on either side to search as a substring in both directions.

tag = request.form["tag"]
search = "%{}%".format(tag)
posts = Post.query.filter(Post.tags.like(search)).all()

Both .done() and .success() are callback functions and they essentially function the same way.

Here's the documentation. The difference is that .success() is deprecated as of jQuery 1.8. You should use .done() instead.

In case you don't want to click the link:

Deprecation Notice

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

A somewhat late answer, but with pandas, it is possible to get directly a column of an excel file:

import pandas

df = pandas.read_excel('sample.xls')
#print the column names
print df.columns
#get the values for a given column
values = df['Arm_id'].values
#get a data frame with selected columns
FORMAT = ['Arm_id', 'DSPName', 'Pincode']
df_selected = df[FORMAT]

Make sure you have installed xlrd and pandas:

pip install pandas xlrd

You Can use this code to read line by line in text file and You could also check about the first character is "*" then you can leave that..

Public Sub Test()

    Dim ReadData as String

    Open "C:\satheesh\myfile\file.txt" For Input As #1

    Do Until EOF(1) 
       Line Input #1, ReadData 'Adding Line to read the whole line, not only first 128 positions
    If Not Left(ReadData, 1) = "*" then
       '' you can write the variable ReadData into the database or file
    End If 

    Loop

    Close #1

End Sub

Move files with filter( using Path, os,shutil modules):

from pathlib import Path
import shutil
import os

src_path ='/media/shakil/New Volume/python/src'
trg_path ='/media/shakil/New Volume/python/trg'

for src_file in Path(src_path).glob('*.txt*'):
    shutil.move(os.path.join(src_path,src_file),trg_path)

You've many options to do that, but the best one is using the AWS CLI.

Here's a walk-through:

1. Download and install AWS CLI in your machine:

   • Install the AWS CLI using the MSI Installer (Windows).
   • Install the AWS CLI using the Bundled Installer for Linux, OS X, or Unix.

2. Configure AWS CLI:

   

   Make sure you input valid access and secret keys, which you received when you created the account.

3. Sync the S3 bucket using:

   aws s3 sync s3://yourbucket /local/path
   

   In the above command, replace the following fields:

   • yourbucket >> your S3 bucket that you want to download.
   • /local/path >> path in your local system where you want to download all the files.

Try using xmltype.createxml(xml).

As in,

select extract(xmltype.createxml(xml), '//fax').getStringVal() from mytab;

It worked for me.

If you want to improve or manipulate even further.

Try something like this.

Select *
from xmltable(xmlnamespaces('some-name-space' as "ns", 
                                  'another-name-space' as "ns1",
                           ), 
                    '/ns/ns1/foo/bar'
                    passing xmltype.createxml(xml) 
                    columns id varchar2(10) path '//ns//ns1/id',
                            idboss varchar2(500) path '//ns0//ns1/idboss',
                            etc....

                    ) nice_xml_table

Hope it helps someone.

Assuming df is your data frame, and that you want to create 75% train and 25% test

all <- 1:nrow(df)
train_i <- sort(sample(all, round(nrow(df)*0.75,digits = 0),replace=FALSE))
test_i <- all[-train_i]

Then to create a train and test data frames

df_train <- df[train_i,]
df_test <- df[test_i,]

Yes, what you are asking for is called AJAX or XMLHttpRequest. You can either use a library like jQuery to simplify making the call (due to cross-browser compatibility issues), or write your own handler.

In jQuery:

$.GET('url.asp', {data: 'here'}, function(data){ /* what to do with the data returned */ })

In plain vanilla javaScript (from w3c):

var xmlhttp;
function loadXMLDoc(url)
{
    xmlhttp=null;
if (window.XMLHttpRequest)
  {// code for all new browsers
      xmlhttp=new XMLHttpRequest();
  }
else if (window.ActiveXObject)
  {// code for IE5 and IE6
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
if (xmlhttp!=null)
  {
      xmlhttp.onreadystatechange=state_Change;
      xmlhttp.open("GET",url,true);
      xmlhttp.send(null);
  }
else
  {
      alert("Your browser does not support XMLHTTP.");
  }
}

function state_Change()
{
    if (xmlhttp.readyState==4)
      {// 4 = "loaded"
          if (xmlhttp.status==200)
            {// 200 = OK
             //xmlhttp.data and shtuff
            // ...our code here...
        }
  else
        {
            alert("Problem retrieving data");
        }
  }
}

One advantage you get with the approach mentioned by @Tom is that you don't have to create any constructors in the SomeManager, and hence limiting the clients to instantiate it.

@RunWith(MockitoJUnitRunner.class)
public class SomeManagerTest {

    @InjectMocks
    private SomeManager someManager;

    @Mock
    private SomeDependency someDependency; // this will be injected into someManager

    //You don't need to instantiate the SomeManager with default contructor at all
   //SomeManager someManager = new SomeManager();    
   //Or SomeManager someManager = new SomeManager(someDependency);

     //tests...

}

Whether its a good practice or not depends on your application design.

This method does the same thing but a little more simply and possibly a little more performant and in the event you are using reflection, it skips those frames automatically. The only issue is it may not be present in non-Sun JVMs, although it is included in the runtime classes of JRockit 1.4-->1.6. (Point is, it is not a public class).

sun.reflect.Reflection

    /** Returns the class of the method <code>realFramesToSkip</code>
        frames up the stack (zero-based), ignoring frames associated
        with java.lang.reflect.Method.invoke() and its implementation.
        The first frame is that associated with this method, so
        <code>getCallerClass(0)</code> returns the Class object for
        sun.reflect.Reflection. Frames associated with
        java.lang.reflect.Method.invoke() and its implementation are
        completely ignored and do not count toward the number of "real"
        frames skipped. */
    public static native Class getCallerClass(int realFramesToSkip);

As far as what the realFramesToSkip value should be, the Sun 1.5 and 1.6 VM versions of java.lang.System, there is a package protected method called getCallerClass() which calls sun.reflect.Reflection.getCallerClass(3), but in my helper utility class I used 4 since there is the added frame of the helper class invocation.

In windows, you need to use double quotes "". So the command would be

git commit -m "t"

I'm going to hazard a historical and practical hot take here:

Yes, according to specifications, <strong> had a semantic meaning in HTML4 and <b> had a strictly presentational meaning.

Yes, when HTML5 came along, new semantic meaning that was slightly different was introduced for b and i.

Yes, the W3C recommends — basically — TL,DR; don't use b and i.

You should always bear in mind that the content of a b element may not always be bold, and that of an i element may not always be italic. The actual style is dependent on the CSS style definitions. You should also bear in mind that bold and italic may not be the preferred style for content in certain languages. You should not use b and i tags if there is a more descriptive and relevant tag available.

BUT:

The real world internet has massive loads of existing HTML that is never going to get updated. The real world internet has to account for content generated and copy and pasted between a vast network of software and CMS systems that all have different developer teams and were built in different eras.

So if you're writing HTML or building a system that writes HTML for other people — sure — definitely use <strong> instead of <b> to mean "strongly emphasized" because it's more semantically correct.

But really, the on-the-ground reality is that the semantic and stylistic meaning of <strong> and <b> have merged over time out of necessity.

If I'm building a CMS that allows any pasting of styled text, I need to plan both for people who are pasting in <b> and mean "strongly emphasized" and for people who are pasting in <strong> and mean "make this text bold". It might not be "right", but it's how the real world works at this moment in time.

And so, if I'm writing a stylesheet for that site, I'm probably going to end up writing some styles that look like this:

b,
strong {
  font-weight: 700;
  /* ... more styles here */
}

i,
em {
  font-style: italic;
  /* ... more styles here */
}

Or, I'm going to rely on the browser defaults, which do the same thing as the code above in every modern browser I know of.

Or, I might be one of probably millions of sites that use normalize.css, which takes care to ensure that b and strong are treated the same.

There's such a massive ocean of HTML out there in the world already that works off of this expectation, I just can't imagine that b will EVER be depreciated in favor of strong or that browsers will ever start displaying them differently by default.

So that's it. That's my hot take on semantics, history and the real world. Are b/i and strong/em the same? No. Will they probably both exist and be treated as identical in almost every situation until the collapse of modern civilization? I think, yes.

This will probably have some performance costs when creating the connection but as connections are pooled, they are created only once and then reused, so it won't make any difference to your application. But as always: measure it.

UPDATE:

There are two authentication modes:

1. Windows Authentication mode (corresponding to a trusted connection). Clients need to be members of a domain.
2. SQL Server Authentication mode. Clients are sending username/password at each connection

SQL Server 2012 above, I prefer use format() function, more simplify.

SELECT format(date,'MM.yyyy') AS Mjesec, SUM(marketingExpense) AS SumaMarketing, SUM(revenue) AS SumaZarada 
FROM [Order]
WHERE (idCustomer = 1) AND (date BETWEEN '2001-11-3' AND '2011-11-3')
GROUP BY format(date,'MM.yyyy')

DateTime birthDate = new DateTime(1981, 8, 9);
Console.WriteLine ("I was born on the {0}. of {1}, {2}.", birthDate.Day, birthDate.ToString("MMMM"), birthDate.Year);

/* The above code will say:
"I was born on the 9. of august, 1981."

"dd" converts to the day (01 thru 31).
"ddd" converts to 3-letter name of day (e.g. mon).
"dddd" converts to full name of day (e.g. monday).
"MMM" converts to 3-letter name of month (e.g. aug).
"MMMM" converts to full name of month (e.g. august).
"yyyy" converts to year.

Update 2012

This is an old question but I think it needs a more up to date answer because now there is a way to have more control of website caching.

In Offline Web Applications (which is really any HTML5 website) applicationCache.swapCache() can be used to update the cached version of your website without the need for manually reloading the page.

This is a code example from the Beginner's Guide to Using the Application Cache on HTML5 Rocks explaining how to update users to the newest version of your site:

// Check if a new cache is available on page load.
window.addEventListener('load', function(e) {

  window.applicationCache.addEventListener('updateready', function(e) {
    if (window.applicationCache.status == window.applicationCache.UPDATEREADY) {
      // Browser downloaded a new app cache.
      // Swap it in and reload the page to get the new hotness.
      window.applicationCache.swapCache();
      if (confirm('A new version of this site is available. Load it?')) {
        window.location.reload();
      }
    } else {
      // Manifest didn't changed. Nothing new to server.
    }
  }, false);

}, false);

Things change quickly on the Web. This question was asked in 2009 and in 2012 I posted an update about a new way to handle the problem described in the question. Another 4 years passed and now it seems that it is already deprecated. Thanks to cgaldiolo for pointing it out in the comments.

Currently, as of July 2016, the HTML Standard, Section 7.9, Offline Web applications includes a deprecation warning:

This feature is in the process of being removed from the Web platform. (This is a long process that takes many years.) Using any of the offline Web application features at this time is highly discouraged. Use service workers instead.

So does Using the application cache on Mozilla Developer Network that I referenced in 2012:

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

See also Bug 1204581 - Add a deprecation notice for AppCache if service worker fetch interception is enabled.

Here is my solution:

/^(2[0-9]{3})-(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01]) (0[0-9]|1[0-9]|2[0123])\:([012345][0-9])\:([012345][0-9])$/u

Short answer: I don't think so. C# .Net is compiled (to bytecode) and can't evaluate strings at runtime, as far as I know. JScript .Net can, however; but I would still advise you to code a parser and stack-based evaluator yourself.

Continue is a keyword in Java & it is used to skip the current iteration.

Suppose you want to print all odd numbers from 1 to 100

public class Main {

    public static void main(String args[]) {

    //Program to print all odd numbers from 1 to 100

        for(int i=1 ; i<=100 ; i++) {
            if(i % 2 == 0) {
                continue;
            }
            System.out.println(i);
        }

    }
}

continue statement in the above program simply skips the iteration when i is even and prints the value of i when it is odd.

Continue statement simply takes you out of the loop without executing the remaining statements inside the loop and triggers the next iteration.

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

You're close. You can strip the whitespace by using the replace method like this:

$answer.replace(' ','')

There needs to be no space or characters between the second set of quotes in the replace method (replacing the whitespace with nothing).

In my case,

Nothing above worked, I had a CSV file copied to Linux machine from my mac and I used all the above commands but nothing helped but the below one

tr "\015" "\n" < inputfile > outputfile

I had a file in which ^M characters were sandwitched between lines something like below

Audi,A4,35 TFSi Premium,,CAAUA4TP^MB01BNKT6TG,TRO_WBFB_500,Trico,CARS,Audi,A4,35 TFSi Premium,,CAAUA4TP^MB01BNKTG0A,TRO_WB_T500,Trico,

Use another flex container to fix the min-height issue in IE10 and IE11:

HTML

<div class="ie-fixMinHeight">
    <div id="page">
        <div id="header"></div>
        <div id="content"></div>
        <div id="footer"></div>
    </div>
</div>

CSS

.ie-fixMinHeight {
    display:flex;
}

#page {
    min-height:100vh;
    width:100%;
    display:flex;
    flex-direction:column;
}

#content {
    flex-grow:1;
}

See a working demo.

• Don't use flexbox layout directly on body because it screws up elements inserted via jQuery plugins (autocomplete, popup, etc.).
• Don't use height:100% or height:100vh on your container because the footer will stick at the bottom of window and won't adapt to long content.
• Use flex-grow:1 rather than flex:1 cause IE10 and IE11 default values for flex are 0 0 auto and not 0 1 auto.

Try to set your procedure as SECURITY INVOKER

Mysql default sets procedures security as "DEFINER" (CREATOR OF).. you must set the security to the "invoker".

• If want to totally delete it use del:

  del your_variable
  

• Or otherwise, to make the value None:

  your_variable = None
  

• If it's a mutable iterable (lists, sets, dictionaries, etc, but not tuples because they're immutable), you can make it empty like:

  your_variable.clear()
  

Then your_variable will be empty

boto3 also has a method for uploading a file directly:

s3 = boto3.resource('s3')    
s3.Bucket('bucketname').upload_file('/local/file/here.txt','folder/sub/path/to/s3key')

http://boto3.readthedocs.io/en/latest/reference/services/s3.html#S3.Bucket.upload_file

What are native methods in Java and where should they be used?

Once you see a small example, it becomes clear:

Main.java:

public class Main {
    public native int intMethod(int i);
    public static void main(String[] args) {
        System.loadLibrary("Main");
        System.out.println(new Main().intMethod(2));
    }
}

Main.c:

#include <jni.h>
#include "Main.h"

JNIEXPORT jint JNICALL Java_Main_intMethod(
    JNIEnv *env, jobject obj, jint i) {
  return i * i;
}

Compile and run:

javac Main.java
javah -jni Main
gcc -shared -fpic -o libMain.so -I${JAVA_HOME}/include \
  -I${JAVA_HOME}/include/linux Main.c
java -Djava.library.path=. Main

Output:

Tested on Ubuntu 14.04 with Oracle JDK 1.8.0_45.

So it is clear that it allows you to:

• call a compiled dynamically loaded library (here written in C) with arbitrary assembly code from Java
• and get results back into Java

This could be used to:

• write faster code on a critical section with better CPU assembly instructions (not CPU portable)
• make direct system calls (not OS portable)

with the tradeoff of lower portability.

It is also possible for you to call Java from C, but you must first create a JVM in C: How to call Java functions from C++?

Example on GitHub for you to play with.

An option for delegates in C++ that is not otherwise mentioned here is to do it C style using a function ptr and a context argument. This is probably the same pattern that many asking this question are trying to avoid. But, the pattern is portable, efficient, and is usable in embedded and kernel code.

class SomeClass
{
    in someMember;
    int SomeFunc( int);

    static void EventFunc( void* this__, int a, int b, int c)
    {
        SomeClass* this_ = static_cast< SomeClass*>( this__);

        this_->SomeFunc( a );
        this_->someMember = b + c;
    }
};

void ScheduleEvent( void (*delegateFunc)( void*, int, int, int), void* delegateContext);

    ...
    SomeClass* someObject = new SomeObject();
    ...
    ScheduleEvent( SomeClass::EventFunc, someObject);
    ...

Go back to your code, and replace 100 by 100.00 and let me know if it works. However, if you want to be formal, try this:

import java.text.DecimalFormat;
DecimalFormat df=new DecimalFormat("0.00");
String formate = df.format(value); 
double finalValue = (Double)df.parse(formate) ;

Keep in mind that this doesn't do any error-checking while decoding - non base 64 encoded data will get processed.

Add a temporary Objective-C file to your project. You may give it any name you like.

Select Yes to configure an Objective-C bridging header.

Delete the temporary Objective-C file you just created.

In the projectName-Bridging-Header.h file just created, add this line:

'#import < GoogleMaps/GoogleMaps.h >'

Edit the AppDelegate.swift file:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    GMSServices.provideAPIKey("AIza....") //iOS API key

    return true
}

I had the same issue,

• Quit Netbeans.
• Delete the JDK9 file in : /Library/Java/JavaVirtualMachines
• Install the JDK8 : Download link

Good luck :)

Try str.replace():

string = "it is icy"
print string.replace("i", "")

The optimal solution for this is provide it as '0' and while using string use it as 'null' when using integer.

ex:

INSERT INTO table_name(column_name) VALUES(NULL);

As of TypeScript 3.7 you can use nullish coalescing operator ??. You can think of this feature as a way to “fall back” to a default value when dealing with null or undefined

let name1:string = person.name ?? '';

The ?? operator can replace uses of || when trying to use a default value and can be used when dealing with booleans, numbers, etc. where || cannot be used.

As of TypeScript 4 you can use ??= assignment operator as a ??= b which is an alternative to a = a ?? b;

Try this -

plt.xticks(rotation=90)

You can use git log to display the diffs while searching:

git log -p -- path/to/file

I can´t answer your question in the comments due to low reputation score.

The next code will give you an error because the paste function return a character string

for(i in 1:length(var.out)) {
   paste("data$", var.out[i], sep="") <- NULL
}

Here is a possible solution:

for(i in 1:length(var.out)) {

  text_to_source <- paste0 ("data$", var.out[i], "<- NULL") # Write a line of your
                                                  # code like a character string
  eval (parse (text=text_to_source)) # Source a text that contains a code
}

or just do:

for(i in 1:length(var.out)) {
  data[var.out[i]] <- NULL
}

You can use as many joins as you want, however, the more you use the more it will impact performance

I have the same today on Win7.x64, this solve it.

I have Done Like this, i have remove all items except the value coming as 1 and 3.

ListItemCollection liCol = ddlcustomertype.Items;
for (int i = 0; i < liCol.Count;i++ )

    ListItem li = liCol[i];
    if (li.Value != "1" || li.Value != "3")
        ddlcustomertype.Items.Remove(li);
}

If you are using spring with application.yml the following will work for you

spring: datasource: url: jdbc:h2:mem:mydb;DB_CLOSE_ON_EXIT=FALSE;MODE=PostgreSQL;INIT=CREATE SCHEMA IF NOT EXISTS calendar

The PostgreSQL manual indicates that this means the transaction is open (inside BEGIN) and idle. It's most likely a user connected using the monitor who is thinking or typing. I have plenty of those on my system, too.

If you're using Slony for replication, however, the Slony-I FAQ suggests idle in transaction may mean that the network connection was terminated abruptly. Check out the discussion in that FAQ for more details.

According to maven website, the last version to support Java 6 is 3.2.5, and 3.3 and up use Java 7. My hunch is that you're using Maven 3.3 or higher, and should either upgrade to Java 7 (and set proper source/target attributes in your pom) or downgrade maven.

If you can use jQuery, look at load. You could then set your function to run after your element finishes loading.

For example, consider a page with a simple image:

<img src="book.png" alt="Book" id="book" />

The event handler can be bound to the image:

$('#book').load(function() {
  // Handler for .load() called.
});

If you need all elements on the current window to load, you can use

$(window).load(function () {
  // run code
});

If you cannot use jQuery, the plain Javascript code is essentially the same amount of (if not less) code:

window.onload = function() {
  // run code
};

FYI, if you want to create an Installer package in VS2010, unfortunately it only targets .NET 4. To work around this, you have to add NET 4.5 as a launch condition.

Add the following in to the Launch Conditions of the installer (Right click, View, Launch Conditions).

In "Search Target Machine", right click and select "Add Registry Search".

Property: REGISTRYVALUE1
RegKey: Software\Microsoft\NET Framework Setup\NDP\v4\Full
Root: vsdrrHKLM
Value: Release

Add new "Launch Condition":

Condition: REGISTRYVALUE1>="#378389"
InstallUrl: http://www.microsoft.com/en-gb/download/details.aspx?id=30653
Message: Setup requires .NET Framework 4.5 to be installed.

Where:

378389 = .NET Framework 4.5

378675 = .NET Framework 4.5.1 installed with Windows 8.1

378758 = .NET Framework 4.5.1 installed on Windows 8, Windows 7 SP1, or Windows Vista SP2

379893 = .NET Framework 4.5.2

Launch condition reference: http://msdn.microsoft.com/en-us/library/vstudio/xxyh2e6a(v=vs.100).aspx

Simple and fully equiped truncate() method:

function truncate($string, $width, $etc = ' ..')
{
    $wrapped = explode('$trun$', wordwrap($string, $width, '$trun$', false), 2);
    return $wrapped[0] . (isset($wrapped[1]) ? $etc : '');
}

This is an example with subprocess library:

import subprocess

python_version = '3'
path_to_run = './'
py_name = '__main__.py'

# args = [f"python{python_version}", f"{path_to_run}{py_name}"]  # Avaible in python3
args = ["python{}".format(python_version), "{}{}".format(path_to_run, py_name)]

res = subprocess.Popen(args, stdout=subprocess.PIPE)
output, error_ = res.communicate()

if not error_:
    print(output)
else:
    print(error_)

Perhaps get the size of the string and loop through each character and call isDigit() on each character. If it is a digit, then add it to a string that only collects the numbers before calling Integer.parseInt().

Something like:

    String something = "423e";
    int length = something.length();
    String result = "";
    for (int i = 0; i < length; i++) {
        Character character = something.charAt(i);
        if (Character.isDigit(character)) {
            result += character;
        }
    }
    System.out.println("result is: " + result);

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

If you happen to have multiple accounts on your mac, chances are, your current account belongs to different user group as the primary account that originally owned /usr/local meaning that none of the solutions above will work.

You can check that by trying to ls -la /usr/local and see what user and group that have permissions to write on the directory. In my case it was root wheel. It may be root admin.

I solved it by adding the current user to the group that primary account has by using the following command.

sudo dseditgroup -o edit -a $(whoami) -t user admin
sudo dseditgroup -o edit -a $(whoami) -t user wheel

There after it worked like a charm. Hopefully it helps someone out there.

I built on sabithpocker's idea and made a more generalized version that lets you control more than one selectbox from a given trigger.

I assigned the selectboxes I wanted to be controlled the classname "switchable," and cloned them all like this:

$j(this).data('options',$j('select.switchable option').clone());

and used a specific naming convention for the switchable selects, which could also translate into classes. In my case, "category" and "issuer" were the select names, and "category_2" and "issuer_1" the class names.

Then I ran an $.each on the select.switchable groups, after making a copy of $(this) for use inside the function:

var that = this;
$j("select.switchable").each(function() { 
    var thisname = $j(this).attr('name');
    var theseoptions = $j(that).data('options').filter( '.' + thisname + '_' + id );
    $j(this).html(theseoptions);
});     

By using a classname on the ones you want to control, the function will safely ignore other selects elsewhere on the page (such as the last one in the example on Fiddle).

Here's a Fiddle with the complete code:

if (mysql_query("INSERT INTO PEOPLE (NAME ) VALUES ('COLE')")or die(mysql_error())) {
  echo 'Success';
} else {
  echo 'Fail';
} 

Although since you have or die(mysql_error()) it will show the mysql_error() on the screen when it fails. You should probably remove that if it isnt the desired result

If you wish to change the font color inside string.xml file, you may try the following code.

<resources>
   <string name="hello_world"><font fgcolor="#ffff0000">Hello world!</font></string>
</resources>

If intake_date is some common date format you can use date() and strtotime()

$mysqlDate = date('Y-m-d H:i:s', strtotime($_POST['intake_date']));

However, this will only work if the date format is accepted by strtotime(). See it's doc page for supported formats.

how does rails know that user_id is a foreign key referencing user?

Rails itself does not know that user_id is a foreign key referencing user. In the first command rails generate model Micropost user_id:integer it only adds a column user_id however rails does not know the use of the col. You need to manually put the line in the Micropost model

class Micropost < ActiveRecord::Base
  belongs_to :user
end

class User < ActiveRecord::Base
  has_many :microposts
end

the keywords belongs_to and has_many determine the relationship between these models and declare user_id as a foreign key to User model.

The later command rails generate model Micropost user:references adds the line belongs_to :user in the Micropost model and hereby declares as a foreign key.

FYI
Declaring the foreign keys using the former method only lets the Rails know about the relationship the models/tables have. The database is unknown about the relationship. Therefore when you generate the EER Diagrams using software like MySql Workbench you find that there is no relationship threads drawn between the models. Like in the following pic

However, if you use the later method you find that you migration file looks like:

def change
    create_table :microposts do |t|
      t.references :user, index: true

      t.timestamps null: false
    end
    add_foreign_key :microposts, :users

Now the foreign key is set at the database level. and you can generate proper EER diagrams.

Not only does it depend on what keeps your users happy, but how much development time do you have? What kind of resources can you throw at the problem (software, hardware, and people)?

I don't mind a couple-few second delay for hosted applications if they're doing something "complex". If it's really simple, delays bother me.

First add a global variable

Context mContext;

Then change your constructor to this

public FeedAdapter(Context context, List<Post> myDataset) {
    mContext = context;
    mDataset = myDataset;
}

The pass your context when creating the adapter.

FeedAdapter myAdapter = new FeedAdapter(this,myDataset);

Follow the steps:

1. npm install --save-dev nodemon

2. Add the following two lines to "script" section of package.json:

"start": "node ./bin/www",
"devstart": "nodemon ./bin/www"

as shown below:

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node ./bin/www",
    "devstart": "nodemon ./bin/www"
}

3. npm run devstart
