If you want to return to your current working directory:

current_dir=$PWD;cd /path/to/your/command/dir;special command ARGS;cd $current_dir;

1. We are setting a variable current_dir equal to your pwd
2. after that we are going to cd to where you need to run your command
3. then we are running the command
4. then we are going to cd back to our variable current_dir

"How do I for example read a 3 bit integer value starting at the second bit?"

int number = // whatever;
uint8_t val; // uint8_t is the smallest data type capable of holding 3 bits
val = (number & (1 << 2 | 1 << 3 | 1 << 4)) >> 2;

(I assumed that "second bit" is bit #2, i. e. the third bit really.)

You better use CSS for that, after all, this is what CSS is for. If you don't want to do that, go with Dorwand's answer.

You should add this line

 self.navigationController?.navigationBar.topItem?.backBarButtonItem?.tintColor = .black

The preprocessor is looking for StdCUtil/split.h in

• ./ (i.e. /root/Core/, the directory that contains the #include statement). So ./ + StdCUtil/split.h = ./StdCUtil/split.h and the file is missing

and in

• $INC_DIR (i.e. ../StdCUtil/ = /root/Core/../StdCUtil/ = /root/StdCUtil/). So ../StdCUtil/ + StdCUtil/split.h = ../StdCUtil/StdCUtil/split.h and the file is missing

You can fix the error changing the $INC_DIR variable (best solution):

$INC_DIR = ../

or the include directive:

#include "split.h"

but in this way you lost the "path syntax" that makes it very clear what namespace or module the header file belongs to.

Reference:

• C++ #include semantics

EDIT/UPDATE

It should also be

CXX = g++
CXXFLAGS = -c -Wall -I$(INC_DIR)

...

%.o: %.cpp $(DEPS)
    $(CXX) -o $@ $< $(CXXFLAGS)

Terminate the query with \G in place of ;. For example:

SELECT * FROM sometable\G

This query displays the rows vertically, like this:

*************************** 1. row ***************************
                 Host: localhost
                   Db: mydatabase1
                 User: myuser1
          Select_priv: Y
          Insert_priv: Y
          Update_priv: Y
          ...
*************************** 2. row ***************************
                 Host: localhost
                   Db: mydatabase2
                 User: myuser2
          Select_priv: Y
          Insert_priv: Y
          Update_priv: Y
          ...

When making a toast in fragment do as following:

Toast.makeText(getActivity(),"Message", Toast.LENGTH_SHORT).show();

When class is extending fragment it is necessary to use getActivity() since fragment is a subclass of activity.

The solution is very simple and worked for me.

Try this :

git pull --rebase <url>

then

git push -u origin master

Try this(need to get first IMEI always)

TelephonyManager mTelephony = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        if (ActivityCompat.checkSelfPermission(LoginActivity.this,Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED) {

         return;
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                if (mTelephony.getPhoneCount() == 2) {
                    IME = mTelephony.getImei(0);
                }else{
                    IME = mTelephony.getImei();
                }
            }else{
                if (mTelephony.getPhoneCount() == 2) {
                    IME = mTelephony.getDeviceId(0);
                } else {
                    IME = mTelephony.getDeviceId();
                }
            }
        } else {
            IME = mTelephony.getDeviceId();
        }

if you have

<span class="label label-default">New</span>

just add the style="font-size:XXpx;", ej.

<span class="label label-default" style="font-size:15px;">New</span>

If you understand stacks with push() and pop() functions, then queue is just to make one of these operations in the oposite sense. Oposite of push() is unshift() and oposite of pop() es shift(). Then:

//classic stack
var stack = [];
stack.push("first"); // push inserts at the end
stack.push("second");
stack.push("last");
stack.pop(); //pop takes the "last" element

//One way to implement queue is to insert elements in the oposite sense than a stack
var queue = [];
queue.unshift("first"); //unshift inserts at the beginning
queue.unshift("second");
queue.unshift("last");
queue.pop(); //"first"

//other way to do queues is to take the elements in the oposite sense than stack
var queue = [];
queue.push("first"); //push, as in the stack inserts at the end
queue.push("second");
queue.push("last");
queue.shift(); //but shift takes the "first" element

I order to change the dialog buttons and background colors, you will need to extend the Dialog theme, eg.:

<style name="MyDialogStyle" parent="android:Theme.Material.Light.Dialog.NoActionBar">
    <item name="android:buttonBarButtonStyle">@style/MyButtonsStyle</item>
    <item name="android:colorBackground">@color/white</item>
</style>

<style name="MyButtonsStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
    <item name="android:textColor">@color/light.blue</item>
</style>

After that, you need to pass this custom style to the dialog builder, eg. like this:

AlertDialog.Builder(requireContext(), R.style.MyDialogStyle)

If you want to change the color of the text inside the dialog, you can pass a custom view to this Builder:

AlertDialog.Builder.setView(View)

or

AlertDialog.Builder.setView(@LayoutResource int)

The ideal datatype for storing Lat Long values in SQL Server is decimal(9,6)

As others have said, this is at approximately 10cm precision, whilst only using 5 bytes of storage.

e.g. CAST(123.456789 as decimal(9,6)) as [LatOrLong]

A workspace is a collection of projects. It's useful to organize your projects when there's correlation between them (e.g.: Project A includes a library, that is provided as a project itself as project B. When you build the workspace project B is compiled and linked in project A).
It's common to use a workspace in the popular CocoaPods. When you install your pods, they are placed inside a workspace, that holds your project and the pod libraries.

        String [] cardValue = {"Ace","2","3","4","5","6","7","8","9","10","King", "Queen", "Jack" };

        List<String> cards = new ArrayList<String>();
        for(int i=0;i<=(cardsType.length)-1;i++){
            for(int j=0;j<=(cardValue.length)-1;j++){
                cards.add(cardsType[i] + " " + "of" + " " + cardValue[j]) ;
            }
        }

        Collections.shuffle(cards);
        System.out.print("Enter the number of cards within:" + cards.size() + " = ");

        Scanner data = new Scanner(System.in);
        Integer inputString = data.nextInt();
        for(int l=0;l<= inputString -1;l++){
            System.out.print( cards.get(l)) ;
        }

With minimal editing to your code (Not sure if they've taught classes or not in your course), change:

def close_window(root): 
    root.destroy()

to

def close_window(): 
    window.destroy()

and it should work.

Explanation:

Your version of close_window is defined to expect a single argument, namely root. Subsequently, any calls to your version of close_window need to have that argument, or Python will give you a run-time error.

When you created a Button, you told the button to run close_window when it is clicked. However, the source code for Button widget is something like:

# class constructor
def __init__(self, some_args, command, more_args):
    #...
    self.command = command
    #...

# this method is called when the user clicks the button
def clicked(self):
    #...
    self.command() # Button calls your function with no arguments.
    #...

As my code states, the Button class will call your function with no arguments. However your function is expecting an argument. Thus you had an error. So, if we take out that argument, so that the function call will execute inside the Button class, we're left with:

def close_window(): 
    root.destroy()

That's not right, though, either, because root is never assigned a value. It would be like typing in print(x) when you haven't defined x, yet.

Looking at your code, I figured you wanted to call destroy on window, so I changed root to window.

Using awk.

i starts at 0, i++ will increment the value of i, but return the original value that i held before being incremented.

awk '{print i++ "," $0}' file

You can specify the key length in the alter table request, something like:

alter table authors ADD UNIQUE(name_first(20), name_second(20));

I think the value for the $_POST['color'] should be read only after checking if its set.

<?php


    if(isset($_POST['color'])) {
      $name = $_POST['color'];  

    echo "You chose the following color(s): <br>";
    foreach ($name as $color){
   echo $color."<br />";
  }} // end brace for if(isset

else {

echo "You did not choose a color.";

}

?>

You can create a single function that calls both of those, and then use it in the event.

function myFunction(){
    pay();
    cls();
}

And then, for the button:

<input id="btn" type="button" value="click" onclick="myFunction();"/>

Here is very good answer of your question

see the example mentioned on above MSDN page :-

Angular v4.4 if you need to save the same reference to the instance of FormArray try this:

purgeForm(form: FormArray) {
  while (0 !== form.length) {
    form.removeAt(0);
  }
}

if you already add project for another storage, like you upload to github and then you upload to bitbucket then it shows this type of Error.

How to remove Error: delete git-hub file in your project and then repeat the following steps...

git init       
git remote add origin [email protected]:Yourname/firstdemotry.git  
git add -A  
git commit -m 'Message'  
git push -u origin master  

As a complement to @JoshuaUlrich answer, here is the definition of function as.Date.character:

as.Date.character
function (x, format = "", ...) 
{
    charToDate <- function(x) {
        xx <- x[1L]
        if (is.na(xx)) {
            j <- 1L
            while (is.na(xx) && (j <- j + 1L) <= length(x)) xx <- x[j]
            if (is.na(xx)) 
                f <- "%Y-%m-%d"
        }
        if (is.na(xx) || !is.na(strptime(xx, f <- "%Y-%m-%d", 
            tz = "GMT")) || !is.na(strptime(xx, f <- "%Y/%m/%d", 
            tz = "GMT"))) 
            return(strptime(x, f))
        stop("character string is not in a standard unambiguous format")
    }
    res <- if (missing(format)) 
        charToDate(x)
    else strptime(x, format, tz = "GMT")
    as.Date(res)
}
<bytecode: 0x265b0ec>
<environment: namespace:base>

So basically if both strptime(x, format="%Y-%m-%d") and strptime(x, format="%Y/%m/%d") throws an NA it is considered ambiguous and if not unambiguous.

Update: User cphyc has kindly created a Github repository for the code in this answer (see here), and bundled the code into a package which may be installed using pip install matplotlib-label-lines.

Pretty Picture:

In matplotlib it's pretty easy to label contour plots (either automatically or by manually placing labels with mouse clicks). There does not (yet) appear to be any equivalent capability to label data series in this fashion! There may be some semantic reason for not including this feature which I am missing.

Regardless, I have written the following module which takes any allows for semi-automatic plot labelling. It requires only numpy and a couple of functions from the standard math library.

Description

The default behaviour of the labelLines function is to space the labels evenly along the x axis (automatically placing at the correct y-value of course). If you want you can just pass an array of the x co-ordinates of each of the labels. You can even tweak the location of one label (as shown in the bottom right plot) and space the rest evenly if you like.

In addition, the label_lines function does not account for the lines which have not had a label assigned in the plot command (or more accurately if the label contains '_line').

Keyword arguments passed to labelLines or labelLine are passed on to the text function call (some keyword arguments are set if the calling code chooses not to specify).

Issues

• Annotation bounding boxes sometimes interfere undesirably with other curves. As shown by the 1 and 10 annotations in the top left plot. I'm not even sure this can be avoided.
• It would be nice to specify a y position instead sometimes.
• It's still an iterative process to get annotations in the right location
• It only works when the x-axis values are floats

Gotchas

• By default, the labelLines function assumes that all data series span the range specified by the axis limits. Take a look at the blue curve in the top left plot of the pretty picture. If there were only data available for the x range 0.5-1 then then we couldn't possibly place a label at the desired location (which is a little less than 0.2). See this question for a particularly nasty example. Right now, the code does not intelligently identify this scenario and re-arrange the labels, however there is a reasonable workaround. The labelLines function takes the xvals argument; a list of x-values specified by the user instead of the default linear distribution across the width. So the user can decide which x-values to use for the label placement of each data series.

Also, I believe this is the first answer to complete the bonus objective of aligning the labels with the curve they're on. :)

label_lines.py:

from math import atan2,degrees
import numpy as np

#Label line with line2D label data
def labelLine(line,x,label=None,align=True,**kwargs):

    ax = line.axes
    xdata = line.get_xdata()
    ydata = line.get_ydata()

    if (x < xdata[0]) or (x > xdata[-1]):
        print('x label location is outside data range!')
        return

    #Find corresponding y co-ordinate and angle of the line
    ip = 1
    for i in range(len(xdata)):
        if x < xdata[i]:
            ip = i
            break

    y = ydata[ip-1] + (ydata[ip]-ydata[ip-1])*(x-xdata[ip-1])/(xdata[ip]-xdata[ip-1])

    if not label:
        label = line.get_label()

    if align:
        #Compute the slope
        dx = xdata[ip] - xdata[ip-1]
        dy = ydata[ip] - ydata[ip-1]
        ang = degrees(atan2(dy,dx))

        #Transform to screen co-ordinates
        pt = np.array([x,y]).reshape((1,2))
        trans_angle = ax.transData.transform_angles(np.array((ang,)),pt)[0]

    else:
        trans_angle = 0

    #Set a bunch of keyword arguments
    if 'color' not in kwargs:
        kwargs['color'] = line.get_color()

    if ('horizontalalignment' not in kwargs) and ('ha' not in kwargs):
        kwargs['ha'] = 'center'

    if ('verticalalignment' not in kwargs) and ('va' not in kwargs):
        kwargs['va'] = 'center'

    if 'backgroundcolor' not in kwargs:
        kwargs['backgroundcolor'] = ax.get_facecolor()

    if 'clip_on' not in kwargs:
        kwargs['clip_on'] = True

    if 'zorder' not in kwargs:
        kwargs['zorder'] = 2.5

    ax.text(x,y,label,rotation=trans_angle,**kwargs)

def labelLines(lines,align=True,xvals=None,**kwargs):

    ax = lines[0].axes
    labLines = []
    labels = []

    #Take only the lines which have labels other than the default ones
    for line in lines:
        label = line.get_label()
        if "_line" not in label:
            labLines.append(line)
            labels.append(label)

    if xvals is None:
        xmin,xmax = ax.get_xlim()
        xvals = np.linspace(xmin,xmax,len(labLines)+2)[1:-1]

    for line,x,label in zip(labLines,xvals,labels):
        labelLine(line,x,label,align,**kwargs)

Test code to generate the pretty picture above:

from matplotlib import pyplot as plt
from scipy.stats import loglaplace,chi2

from labellines import *

X = np.linspace(0,1,500)
A = [1,2,5,10,20]
funcs = [np.arctan,np.sin,loglaplace(4).pdf,chi2(5).pdf]

plt.subplot(221)
for a in A:
    plt.plot(X,np.arctan(a*X),label=str(a))

labelLines(plt.gca().get_lines(),zorder=2.5)

plt.subplot(222)
for a in A:
    plt.plot(X,np.sin(a*X),label=str(a))

labelLines(plt.gca().get_lines(),align=False,fontsize=14)

plt.subplot(223)
for a in A:
    plt.plot(X,loglaplace(4).pdf(a*X),label=str(a))

xvals = [0.8,0.55,0.22,0.104,0.045]
labelLines(plt.gca().get_lines(),align=False,xvals=xvals,color='k')

plt.subplot(224)
for a in A:
    plt.plot(X,chi2(5).pdf(a*X),label=str(a))

lines = plt.gca().get_lines()
l1=lines[-1]
labelLine(l1,0.6,label=r'$Re=${}'.format(l1.get_label()),ha='left',va='bottom',align = False)
labelLines(lines[:-1],align=False)

plt.show()

Similar to tight_layout matplotlib now (as of version 2.2) provides constrained_layout. In contrast to tight_layout, which may be called any time in the code for a single optimized layout, constrained_layout is a property, which may be active and will optimze the layout before every drawing step.

Hence it needs to be activated before or during subplot creation, such as figure(constrained_layout=True) or subplots(constrained_layout=True).

Example:

import matplotlib.pyplot as plt

fig, axes = plt.subplots(4,4, constrained_layout=True)

plt.show()

constrained_layout may as well be set via rcParams

plt.rcParams['figure.constrained_layout.use'] = True

See the what's new entry and the Constrained Layout Guide

Another way to do this would be to add before adding lines in your output, the following line :

output.writerow(dict(zip(dr.fieldnames, dr.fieldnames)))

The zip would return a list of doublet containing the same value. This list could be used to initiate a dictionary.

This worked for me. Create WebViewClient like this below and set the webclient to your webview. I had to use webview.loadDataWithBaseURL as my urls (in my content) did not have the baseurl but only relative urls. You will get the url correctly only when there is a baseurl set using loadDataWithBaseURL.

public WebViewClient getWebViewClientWithCustomHeader(){
    return new WebViewClient() {
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
            try {
                OkHttpClient httpClient = new OkHttpClient();
                com.squareup.okhttp.Request request = new com.squareup.okhttp.Request.Builder()
                        .url(url.trim())
                        .addHeader("<your-custom-header-name>", "<your-custom-header-value>")
                        .build();
                com.squareup.okhttp.Response response = httpClient.newCall(request).execute();

                return new WebResourceResponse(
                        response.header("content-type", response.body().contentType().type()), // You can set something other as default content-type
                        response.header("content-encoding", "utf-8"),  // Again, you can set another encoding as default
                        response.body().byteStream()
                );
            } catch (ClientProtocolException e) {
                //return null to tell WebView we failed to fetch it WebView should try again.
                return null;
            } catch (IOException e) {
                //return null to tell WebView we failed to fetch it WebView should try again.
                return null;
            }
        }
    };

}

Why hasn't anyone thought it was worth mentioning Scanner?

Scanner input = new Scanner(new File("foo.txt"));

while (input.hasNextLine())
{
   System.out.println(input.nextLine());
}

var month = 5;
var cultureSwe = "sv-SE";
var monthSwe = CultureInfo.CreateSpecificCulture(cultureSwe).DateTimeFormat.GetAbbreviatedMonthName(month);
Console.WriteLine(monthSwe);

var cultureEn = "en-US";
var monthEn = CultureInfo.CreateSpecificCulture(cultureEn).DateTimeFormat.GetAbbreviatedMonthName(month);
Console.WriteLine(monthEn);

Output

Since you mentioned Task Manager, I'll guess you're using Windows. Assuming you're running your script within the editor, if you aren't opposed to quitting the editor at the same time as quitting the running program, the keyboard shortcut to end a process is:

Alt + F4

(By which I mean press the 'Alt' and 'F4' keys on your keyboard simultaneously.)

Alternatively, as mentioned in other answers,

Ctrl + C

should also work, but will not quit the editor.

For brevity, we can understand these two APIs like below:

1. X.class.isAssignableFrom(Y.class)

If X and Y are the same class, or X is Y's super class or super interface, return true, otherwise, false.

2. X.class.isInstance(y)

Say y is an instance of class Y, if X and Y are the same class, or X is Y's super class or super interface, return true, otherwise, false.

One way to give preference to specific rows is to add a large number to their priority. You can do this with a CASE statement:

  select id, name, priority
    from mytable
order by priority + CASE WHEN name='core' THEN 1000 ELSE 0 END desc

I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false} property for window.addEventListener, which is recommended as the only working solution, for example here.

In the end, after many tries, I found a way that works for me in both Firefox and Chrome:

window.addEventListener('keydown', (e) => {
    if (e.target.localName != 'input') {   // if you need to filter <input> elements
        switch (e.keyCode) {
            case 37: // left
            case 39: // right
                e.preventDefault();
                break;
            case 38: // up
            case 40: // down
                e.preventDefault();
                break;
            default:
                break;
        }
    }
}, {
    capture: true,   // this disables arrow key scrolling in modern Chrome
    passive: false   // this is optional, my code works without it
});

Quote for EventTarget.addEventListener() from MDN

options Optional
   An options object specifies characteristics about the event listener. The available options are:

capture
   A Boolean indicating that events of this type will be dispatched to the registered listener before being dispatched to any EventTarget beneath it in the DOM tree.
once
   ...
passive
   A Boolean that, if true, indicates that the function specified by listener will never call preventDefault(). If a passive listener does call preventDefault(), the user agent will do nothing other than generate a console warning. ...

1. The protocol is available as req.protocol. docs here

   1. Before express 3.0, the protocol you can assume to be http unless you see that req.get('X-Forwarded-Protocol') is set and has the value https, in which case you know that's your protocol

2. The host comes from req.get('host') as Gopal has indicated

3. Hopefully you don't need a non-standard port in your URLs, but if you did need to know it you'd have it in your application state because it's whatever you passed to app.listen at server startup time. However, in the case of local development on a non-standard port, Chrome seems to include the port in the host header so req.get('host') returns localhost:3000, for example. So at least for the cases of a production site on a standard port and browsing directly to your express app (without reverse proxy), the host header seems to do the right thing regarding the port in the URL.

4. The path comes from req.originalUrl (thanks @pgrassant). Note this DOES include the query string. docs here on req.url and req.originalUrl. Depending on what you intend to do with the URL, originalUrl may or may not be the correct value as compared to req.url.

Combine those all together to reconstruct the absolute URL.

  var fullUrl = req.protocol + '://' + req.get('host') + req.originalUrl;

Use isGlobalPhoneNumber() method of PhoneNumberUtils to detect whether a number is valid phone number or not.

Example

System.out.println("....g1..."+PhoneNumberUtils.isGlobalPhoneNumber("+912012185234"));
System.out.println("....g2..."+PhoneNumberUtils.isGlobalPhoneNumber("120121852f4"));

The result of first print statement is true while the result of second is false because the second phone number contains f.

There are a bunch of different reasons for the "Too Many Connections" error.

Check out this FAQ page on MySQL.com: http://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html

Check your my.cnf file for "max_connections". If none exist try:

[mysqld]
set-variable=max_connections=250

However the default is 151, so you should be okay.

If you are on a shared host, it might be that other users are taking up too many connections.

Other problems to look out for is the use of persistent connections and running out of diskspace.

You can't stretch a background image (until CSS 3).

You would have to use absolute positioning, so that you can put an image tag inside the cell and stretch it to cover the entire cell, then put the content on top of the image.

array.sort(key = lambda x:x[1])

You can easily sort using this snippet, where 1 is the index of the element.

1. Spring is an IoC container (at least the core of Spring) and is used to wire things using dependency injection. Spring provides additional services like transaction management and seamless integration of various other technologies.
2. Struts is an action-based presentation framework (but don't use it for a new development).
3. Struts 2 is an action-based presentation framework, the version 2 of the above (created from a merge of WebWork with Struts).
4. Hibernate is an object-relational mapping tool, a persistence framework.
5. JavaServer Faces is component-based presentation framework.
6. JavaServer Pages is a view technology used by all mentioned presentation framework for the view.
7. Tapestry is another component-based presentation framework.

So, to summarize:

• Struts 2, JSF, Tapestry (and Wicket, Spring MVC, Stripes) are presentation frameworks. If you use one of them, you don't use another.
• Hibernate is a persistence framework and is used to persist Java objects in a relational database.
• Spring can be used to wire all this together and to provide declarative transaction management.

I don't want to make things more confusing but note that Java EE 6 provides modern, standardized and very nice equivalent of the above frameworks: JSF 2.0 and Facelets for the presentation, JPA 2.0 for the persistence, Dependency Injection, etc. For a new development, this is IMO a serious option, Java EE 6 is a great stack.

Here is an example with @RequestBody, First look at the controller !!

  public ResponseEntity<Void> postNewProductDto(@RequestBody NewProductDto newProductDto) {

   ...
        productService.registerProductDto(newProductDto);
        return new ResponseEntity<>(HttpStatus.CREATED);
   ....

}

And here is angular controller

function postNewProductDto() {
                var url = "/admin/products/newItem";
                $http.post(url, vm.newProductDto).then(function () {
                            //other things go here...
                            vm.newProductMessage = "Product successful registered";
                        }
                        ,
                        function (errResponse) {
                            //handling errors ....
                        }
                );
            }

And a short look at form

 <label>Name: </label>
 <input ng-model="vm.newProductDto.name" />

<label>Price </label> 
 <input ng-model="vm.newProductDto.price"/>

 <label>Quantity </label>
  <input ng-model="vm.newProductDto.quantity"/>

 <label>Image </label>
 <input ng-model="vm.newProductDto.photo"/>

 <Button ng-click="vm.postNewProductDto()" >Insert Item</Button>

 <label > {{vm.newProductMessage}} </label>

swift 4.2 and above

}

Note also that table names are case sensitive on Linux unless you set the lower_case_table_name config directive to 1. This is because tables are represented by files which are case sensitive in Linux.

Especially beware of development on Windows which is not case sensitive and deploying to production where it is. For example:

"SELECT * from mytable" 

against table myTable will succeed in Windows but fail in Linux, again, unless the abovementioned directive is set.

Reference here: http://dev.mysql.com/doc/refman/5.0/en/identifier-case-sensitivity.html

The following statement causes a user's password to expire:

ALTER USER user PASSWORD EXPIRE;

If you cause a database user's password to expire with PASSWORD EXPIRE, then the user (or the DBA) must change the password before attempting to log in to the database following the expiration. Tools such as SQL*Plus allow the user to change the password on the first attempted login following the expiration.

ALTER USER scott IDENTIFIED BY password;

Will set/reset the users password.

See the alter user doc for more info

This is a solution how to make autocomplete drop down list with VBA :

Firstly you need to insert a combo box into the worksheet and change its properties, and then running the VBA code to enable the autocomplete.

1. Get into the worksheet which contains the drop down list you want it to be autocompleted.

2. Before inserting the Combo box, you need to enable the Developer tab in the ribbon.

a). In Excel 2010 and 2013, click File > Options. And in the Options dialog box, click Customize Ribbon in the right pane, check the Developer box, then click the OK button.

b). In Outlook 2007, click Office button > Excel Options. In the Excel Options dialog box, click Popular in the right bar, then check the Show Developer tabin the Ribbon box, and finally click the OK button.

3. Then click Developer > Insert > Combo Box under ActiveX Controls.

4. Draw the combo box in current opened worksheet and right click it. Select Properties in the right-clicking menu.

5. Turn off the Design Mode with clicking Developer > Design Mode.

6. Right click on the current opened worksheet tab and click View Code.

7. Make sure that the current worksheet code editor is opened, and then copy and paste the below VBA code into it.

Code borrowed from extendoffice.com

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'Update by Extendoffice: 2018/9/21
    Dim xCombox As OLEObject
    Dim xStr As String
    Dim xWs As Worksheet
    Dim xArr



    Set xWs = Application.ActiveSheet
    On Error Resume Next
    Set xCombox = xWs.OLEObjects("TempCombo")
    With xCombox
        .ListFillRange = ""
        .LinkedCell = ""
        .Visible = False
    End With
    If Target.Validation.Type = 3 Then
        Target.Validation.InCellDropdown = False
        Cancel = True
        xStr = Target.Validation.Formula1
        xStr = Right(xStr, Len(xStr) - 1)
        If xStr = "" Then Exit Sub
        With xCombox
            .Visible = True
            .Left = Target.Left
            .Top = Target.Top
            .Width = Target.Width + 5
            .Height = Target.Height + 5
            .ListFillRange = xStr
            If .ListFillRange = "" Then
                xArr = Split(xStr, ",")
                Me.TempCombo.List = xArr
            End If
            .LinkedCell = Target.Address
        End With
        xCombox.Activate
        Me.TempCombo.DropDown
    End If
End Sub

Private Sub TempCombo_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
    Select Case KeyCode
        Case 9
            Application.ActiveCell.Offset(0, 1).Activate
        Case 13
            Application.ActiveCell.Offset(1, 0).Activate
    End Select
End Sub

9. Click File > Close and Return to Microsoft Excel to close the Microsoft Visual Basic for Application window.

10. Now, just click the cell with drop down list, you can see the drop-down list is displayed as a combo box, then type the first letter into the box, the corresponding word will be completed automatically.

Note: This VBA code is not applied to merged cells.

you can use Action inside Constructor

 public class ViewModel
    {
        public ObservableCollection<TData> Data { get; set; }
       public ViewModel()
        {              
            new Action(async () =>
            {
                  Data = await GetDataTask();
            }).Invoke();
        }

        public Task<ObservableCollection<TData>> GetDataTask()
        {
            Task<ObservableCollection<TData>> task;
            //Create a task which represents getting the data
            return task;
        }
    }

Try

out=$(cat)

Then paste your lines and press Ctrl-D (insert EOF character). All input till Ctrl-D will be redirected to cat's stdout.

Solution When Using form_with helper

<%= f.submit, "Submit", class: 'btn btn-primary' %>

Don't forget the comma after the f.submit method!

HTH!

Restart the computer after has added new value to PATH.

First you need to separate your class from the further extensions ex you cannot extend AddAddressComponent.defaultProps within the class instead move it outside.

I will also recommend you to read about the Constructor and React's lifecycle: see Component Specs and Lifecycle

Here is what you want:

import PropTypes from 'prop-types';

class AddAddressComponent extends React.Component {
  render() {
    let { provinceList, cityList } = this.props;
    if(cityList === undefined || provinceList === undefined){
      console.log('undefined props');
    }
  }
}

AddAddressComponent.contextTypes = {
  router: PropTypes.object.isRequired
};

AddAddressComponent.defaultProps = {
  cityList: [],
  provinceList: [],
};

AddAddressComponent.propTypes = {
  userInfo: PropTypes.object,
  cityList: PropTypes.array.isRequired,
  provinceList: PropTypes.array.isRequired,
}

export default AddAddressComponent;

There may simply not be such a guide. If so, you may not have much luck convincing anybody to write one, because it would be a lot of work.

I would recommend either of two things. The easier one is to follow the guide you have slavishly, which means forgetting about msysgit.

The harder one is to put up a Linux server - perhaps as a guest under Windows using VirtualBox (free) or VMWare or Parallels (pay), and then follow one of the many sets of instructions Google will lead you to. But you will probably find those instructions are insufficient - they usually assume you've already set up an ssh server, for example, so you have to get that info elsewhere. I've done that twice, and can say that unless you're already something of a Linux guru, it will be a struggle.

Your second way is correct.

def foo(opts: dict = {}):
    pass

print(foo.__annotations__)

this outputs

{'opts': <class 'dict'>}

It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.

I strongly advise against using mutable keyword arguments. More information here.

If you're using C#, you can either get all the matches at once (i.e. use Regex.Matches(), which returns a MatchCollection, and check the index of the item: index % 2 != 0).

If you want to find the occurrence to replace it, use one of the overloads of Regex.Replace() that uses a MatchEvaluator (e.g. Regex.Replace(String, String, MatchEvaluator). Here's the code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Text.RegularExpressions;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input = "abcdabcd";

            // Replace *second* a with m

            string replacedString = Regex.Replace(
                input,
                "a",
                new SecondOccuranceFinder("m").MatchEvaluator);

            Console.WriteLine(replacedString);
            Console.Read();

        }

        class SecondOccuranceFinder
        {
            public SecondOccuranceFinder(string replaceWith)
            {
                _replaceWith = replaceWith;
                _matchEvaluator = new MatchEvaluator(IsSecondOccurance);
            }

            private string _replaceWith;

            private MatchEvaluator _matchEvaluator;
            public MatchEvaluator MatchEvaluator
            {
                get
                {
                    return _matchEvaluator;
                }
            }

            private int _matchIndex;
            public string IsSecondOccurance(Match m)
            {
                _matchIndex++;
                if (_matchIndex % 2 == 0)
                    return _replaceWith;
                else
                    return m.Value;
            }
        }
    }
}

Here's how to use a Jet OLEDB or Ace OLEDB Access DB:

using System.Data;
using System.Data.OleDb;

string myConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
                           "Data Source=C:\myPath\myFile.mdb;" +                                    
                           "Persist Security Info=True;" +
                           "Jet OLEDB:Database Password=myPassword;";
try
{
    // Open OleDb Connection
    OleDbConnection myConnection = new OleDbConnection();
    myConnection.ConnectionString = myConnectionString;
    myConnection.Open();

    // Execute Queries
    OleDbCommand cmd = myConnection.CreateCommand();
    cmd.CommandText = "SELECT * FROM `myTable`";
    OleDbDataReader reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); // close conn after complete

    // Load the result into a DataTable
    DataTable myDataTable = new DataTable();
    myDataTable.Load(reader);
}
catch (Exception ex)
{
    Console.WriteLine("OLEDB Connection FAILED: " + ex.Message);
}

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

in your home-dir in file ".gitconfig" add the following

[alias]
sha = rev-parse HEAD

then you will have an easier command to remember:

$ git sha
59fbfdbadb43ad0b6154c982c997041e9e53b600

the val function called from the select will return an array if its a multiple. $('select#my_multiselect').val() will return an array of the values for the selected options - you dont need to loop through and get them yourself.

As others have mentioned, dictionaries are inherently unordered. However, if the issue is merely displaying dictionaries in an ordered fashion, you can override the __str__ method in a dictionary subclass, and use this dictionary class rather than the builtin dict. Eg.

class SortedDisplayDict(dict):
   def __str__(self):
       return "{" + ", ".join("%r: %r" % (key, self[key]) for key in sorted(self)) + "}"


>>> d = SortedDisplayDict({2:3, 1:89, 4:5, 3:0})
>>> d
{1: 89, 2: 3, 3: 0, 4: 5}

Note, this changes nothing about how the keys are stored, the order they will come back when you iterate over them etc, just how they're displayed with print or at the python console.

You can use like this:

String Query = "Select * from " + TABLE_NAME + " where " + Cust_id + " = " + cust_no;

Cursor cursorr = db.rawQuery(Query, null);
if(cursor.getCount() <= 0){
cursorr.close();
}
cursor.close();

Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.

I know I'm am very late on this, but here some usefull samples:

'select the used cells in column 3 of worksheet wks
wks.columns(3).SpecialCells(xlCellTypeConstants).Select

or

'change all formulas in col 3 to values
with sheet1.columns(3).SpecialCells(xlCellTypeFormulas)
    .value = .value
end with

To find the last used row in column, never rely on LastCell, which is unreliable (it is not reset after deleting data). Instead, I use someting like

 lngLast = cells(rows.count,3).end(xlUp).row

Try this:

CREATE TABLE IF NOT EXISTS app_user (
  username varchar(45) NOT NULL,
  password varchar(450) NOT NULL,
  enabled integer NOT NULL DEFAULT '1',
  PRIMARY KEY (username)
)

select age(timestamp_A, timestamp_B)

Answering to Igor's comment:

select age('2013-02-28 11:01:28'::timestamp, '2011-12-31 11:00'::timestamp);
              age              
-------------------------------
 1 year 1 mon 28 days 00:01:28

Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.ENGLISH);
cal.setTime(sdf.parse("Mon Mar 14 16:02:37 GMT 2011"));// all done

note: set Locale according to your environment/requirement

• Javadoc

Please see here: static const vs define

usually a const declaration (notice it doesn't need to be static) is the way to go

var str = "texttexttext";
var arr = ["asd", "ghj", "xtte"];
for (var i = 0, len = arr.length; i < len; ++i) {
    if (str.indexOf(arr[i]) != -1) {
        // str contains arr[i]
    }
}

edit: If the order of the tests doesn't matter, you could use this (with only one loop variable):

var str = "texttexttext";
var arr = ["asd", "ghj", "xtte"];
for (var i = arr.length - 1; i >= 0; --i) {
    if (str.indexOf(arr[i]) != -1) {
        // str contains arr[i]
    }
}

You can't call it asynchronously, since there is no asynchronous property support, only async methods. As such, there are two options, both taking advantage of the fact that asynchronous methods in the CTP are really just a method that returns Task<T> or Task:

// Make the property return a Task<T>
public Task<IEnumerable> MyList
{
    get
    {
         // Just call the method
         return MyAsyncMethod();
    }
}

Or:

// Make the property blocking
public IEnumerable MyList
{
    get
    {
         // Block via .Result
         return MyAsyncMethod().Result;
    }
}

I would suggest you check out the various tutorials that are coming out lately. My current fav is:

Hope this helps.

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

I think you should try

data = {"shareInfo":[{"id":"1","a":"sss","b":"sss","question":"whi?"},
{"id":"2","a":"sss","b":"sss","question":"whi?"},
{"id":"3","a":"sss","b":"sss","question":"whi?"},
{"id":"4","a":"sss","b":"sss","question":"whi?"}]};

ShareInfoLength = data.shareInfo.length;
alert(ShareInfoLength);
for(var i=0; i<ShareInfoLength; i++)
{
alert(Object.keys(data.shareInfo[i]).length);
}

Below is what I have created from the comments here, as well as fixing bugs not mentioned (such as actually returning null, and not 'null'):

function getURLParameter(name) {
    return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null;
}

The vertical-align css attribute doesn't do what you expect unfortunately. This article explains 2 ways to vertically align an element using css.

Try it like this:

Replace("\\\"","");

This will replace occurrences of \" with empty string.

Ex:

string t = "\\\"the dog is my friend\\\"";
t = t.Replace("\\\"","");

This will result in:

the dog is my friend

I might be late to the party but as of my build 3176 it appears the bug is fixed. Just used Ctrl+T and it worked for a CSS file (Kubuntu 18.10)

use position:fixed instead of position:absolute

The first one is relative to your screen window. (not affected by scrolling)

The second one is relative to the page. (affected by scrolling)

Note : IE6 doesn't support position:fixed.

Thanks unwired your solution was very clean. I was using horizontal bootstrap forms and made a couple modifications to allow for a single handler and form css.

html: - UPDATED to use Bootstrap's has-feedback and form-control-feedback

 <div class="container">
  <form class="form-horizontal">
   <div class="form-group has-feedback">
    <label for="txt1" class="col-sm-2 control-label">Label 1</label>
    <div class="col-sm-10">
     <input id="txt1" type="text" class="form-control hasclear" placeholder="Textbox 1">
     <span class="clearer glyphicon glyphicon-remove-circle form-control-feedback"></span>
    </div>
   </div>
   <div class="form-group has-feedback">
    <label for="txt2" class="col-sm-2 control-label">Label 2</label>
    <div class="col-sm-10">
      <input id="txt2" type="text" class="form-control hasclear" placeholder="Textbox 2">
      <span class="clearer glyphicon glyphicon-remove-circle form-control-feedback"></span>
    </div>
   </div>
   <div class="form-group has-feedback">
    <label for="txt3" class="col-sm-2 control-label">Label 3</label>
    <div class="col-sm-10">
     <input id="txt3" type="text" class="form-control hasclear" placeholder="Textbox 3">
     <span class="clearer glyphicon glyphicon-remove-circle form-control-feedback"></span>
    </div>   
   </div>
  </form>
 </div>

javascript:

$(".hasclear").keyup(function () {
    var t = $(this);
    t.next('span').toggle(Boolean(t.val()));
});
$(".clearer").hide($(this).prev('input').val());
$(".clearer").click(function () {
    $(this).prev('input').val('').focus();
    $(this).hide();
});

Proximity Sensor Dial

*#*#7378423#*#*

1) Service Tests - (If present)

2) Proximity Switch

3) Test on sensor (Next to logo(top) of mobile)

4) Yes if works, then u can keep on and proximity switch forever which gives beep all the time and consumes lot of battery

OR

4) No it doesn't work - Then simply clean the mobile screen or screen guard and clear the blocked screen from sensor. It works charm.

Technically, Its not any software solution, but hardware solution will work.

In support of the answer that @tetra gave, I want to point out that if the image is an SVG, then resizing the actual image is not necessary.

Since an SVG file is just XML you can specify whatever size you want it to appear within the XML.

However, if you are using the same SVG image in different places and need it to be different sizes, then using background-size is very helpful. SVG files are inherently smaller than raster images anyway and resizing on the fly with CSS can be very helpful without any performance cost that I am aware of, and certainly little to no loss of quality.

Here is a quick example:

<div class="hasBackgroundImage">content</div>

.hasBackgroundImage
{
    background: transparent url('/image/background.svg') no-repeat 10px 5px;
    background-size: 1.4em;
}

(Note: this works for me in OS X 10.7 with Firefox 8, Safari 5.1, and Chrome 16.0.912.63)

You say that the matrices are the same dimensions, and yet you are trying to perform matrix multiplication on them. Multiplication of matrices with the same dimension is only possible if they are square. In your case, you get an assertion error, because the dimensions are not square. You have to be careful when multiplying matrices, as there are two possible meanings of multiply.

Matrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple * operator:

C = A * B

Element-wise multiplication is where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using the mul() function:

output = A.mul(B);

I found this generator based approach more satisfying:

def split_keep(string, sep):
    """Usage:
    >>> list(split_keep("a.b.c.d", "."))
    ['a.', 'b.', 'c.', 'd']
    """
    start = 0
    while True:
        end = string.find(sep, start) + 1
        if end == 0:
            break
        yield string[start:end]
        start = end
    yield string[start:]

It avoids the need to figure out the correct regex, while in theory should be fairly cheap. It doesn't create new string objects and, delegates most of the iteration work to the efficient find method.

... and in Python 3.8 it can be as short as:

def split_keep(string, sep):
    start = 0
    while (end := string.find(sep, start) + 1) > 0:
        yield string[start:end]
        start = end
    yield string[start:]

This will also work:

$(".myclass[reference='12345']").css('border', '#000 solid 1px');

One statement can be written as such:

someValues.forEach(x => console.log(x));

or multiple statements can be enclosed in {} like this:

someValues.forEach(x => { let a = 2 + x; console.log(a); });

Xcode 9 introduced new tricks with XCTWaiter

Test case waits explicitly

wait(for: [documentExpectation], timeout: 10)

Waiter instance delegates to test

XCTWaiter(delegate: self).wait(for: [documentExpectation], timeout: 10)

Waiter class returns result

let result = XCTWaiter.wait(for: [documentExpectation], timeout: 10)
switch(result) {
case .completed:
    //all expectations were fulfilled before timeout!
case .timedOut:
    //timed out before all of its expectations were fulfilled
case .incorrectOrder:
    //expectations were not fulfilled in the required order
case .invertedFulfillment:
    //an inverted expectation was fulfilled
case .interrupted:
    //waiter was interrupted before completed or timedOut
}

sample usage

Before Xcode 9

Objective C

- (void)waitForElementToAppear:(XCUIElement *)element withTimeout:(NSTimeInterval)timeout
{
    NSUInteger line = __LINE__;
    NSString *file = [NSString stringWithUTF8String:__FILE__];
    NSPredicate *existsPredicate = [NSPredicate predicateWithFormat:@"exists == true"];

    [self expectationForPredicate:existsPredicate evaluatedWithObject:element handler:nil];

    [self waitForExpectationsWithTimeout:timeout handler:^(NSError * _Nullable error) {
        if (error != nil) {
            NSString *message = [NSString stringWithFormat:@"Failed to find %@ after %f seconds",element,timeout];
            [self recordFailureWithDescription:message inFile:file atLine:line expected:YES];
        }
    }];
}

USAGE

XCUIElement *element = app.staticTexts["Name of your element"];
[self waitForElementToAppear:element withTimeout:5];

Swift

func waitForElementToAppear(element: XCUIElement, timeout: NSTimeInterval = 5,  file: String = #file, line: UInt = #line) {
        let existsPredicate = NSPredicate(format: "exists == true")

        expectationForPredicate(existsPredicate,
                evaluatedWithObject: element, handler: nil)

        waitForExpectationsWithTimeout(timeout) { (error) -> Void in
            if (error != nil) {
                let message = "Failed to find \(element) after \(timeout) seconds."
                self.recordFailureWithDescription(message, inFile: file, atLine: line, expected: true)
            }
        }
    }

USAGE

let element = app.staticTexts["Name of your element"]
self.waitForElementToAppear(element)

or

let element = app.staticTexts["Name of your element"]
self.waitForElementToAppear(element, timeout: 10)

SOURCE

If you only want one or more columns in the front and don't care about the order of the rest:

require(dplyr)
test %>%
  select(B, everything())

Implement OnClickListener() on your Activity...

public class MyActivity extends Activity implements View.OnClickListener {
}

For each button use...

buttonX.setOnClickListener(this);

In your Activity onClick() method test for which button it is...

@Override
public void onClick(View view) {
    if (View.equals(buttonX))
        // Do something
}

Also in onClick you could use view.getId() to get the resource ID and then use that in a switch/case block to identify each button and perform the relevant action.

Note that if you have committed a bunch of changes in various submodules, you can (or will be soon able to) push everything in one go (ie one push from the parent repo), with:

git push --recurse-submodules=on-demand

git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

--recurse-submodules=<check|on-demand|no>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

Here is one that we have saved off to findcol.sql so we can run it easily from within SQLPlus

Python is strongly typed. There are no implicit type conversions.

You have to do one of these:

"asd%d" % 9
"asd" + str(9)

Something like this might help:

SET Today=%Date:~10,4%%Date:~4,2%%Date:~7,2%
mkdir C:\Test\Backup-%Today%
move C:\Test\Log\*.* C:\Test\Backup-%Today%\
SET Today=

The important part is the first line. It takes the output of the internal DATE value and parses it into an environmental variable named Today, in the format CCYYMMDD, as in '20110407`.

The %Date:~10,4% says to extract a *substring of the Date environmental variable 'Thu 04/07/2011' (built in - type echo %Date% at a command prompt) starting at position 10 for 4 characters (2011). It then concatenates another substring of Date: starting at position 4 for 2 chars (04), and then concats two additional characters starting at position 7 (07).

*The substring value starting points are 0-based.

You may need to adjust these values depending on the date format in your locale, but this should give you a starting point.

Can't add a comment to the excellent explanation in the other post but wanted to mention that a great documentation source can be found here.

It is enough to register an event function for accelerometer like so:

if(window.DeviceMotionEvent){
  window.addEventListener("devicemotion", motion, false);
}else{
  console.log("DeviceMotionEvent is not supported");
}

with the handler:

function motion(event){
  console.log("Accelerometer: "
    + event.accelerationIncludingGravity.x + ", "
    + event.accelerationIncludingGravity.y + ", "
    + event.accelerationIncludingGravity.z
  );
}

And for magnetometer a following event handler has to be registered:

if(window.DeviceOrientationEvent){
  window.addEventListener("deviceorientation", orientation, false);
}else{
  console.log("DeviceOrientationEvent is not supported");
}

with a handler:

function orientation(event){
  console.log("Magnetometer: "
    + event.alpha + ", "
    + event.beta + ", "
    + event.gamma
  );
}

There are also fields specified in the motion event for a gyroscope but that does not seem to be universally supported (e.g. it didn't work on a Samsung Galaxy Note).

There is a simple working code on GitHub

Basic and general difference is:

Fields

• ALWAYS give both get and set access
• CAN NOT cause side effects (throwing exceptions, calling methods, changing fields except the one being got/set, etc)

Properties

• NOT ALWAYS give both get and set access
• CAN cause side effects

As of 2014, you can trigger the click on a <a/> tag. However, for security reasons, you have to do it in a click event handler, or the browser will tag it as a popup (some other events may allow you to safely trigger the opening).

I try this same method, but with a different list with more values in the function map. My problem was to forget a return statement. This is very important :)

 bottom: new TabBar(
      controller: _controller,
      isScrollable: true,
      tabs:
        moviesTitles.map((title) { return Tab(text: title)}).toList()
      ,
    ),

{
    "preOrderData" : [
        {
            "pname": "xyz",
            "quantity": "1",
            "unit": "Peice",
            "description": "xyz 100 gram",
            "preferred_brand": "xyz",
            "entry_date": "2020-10-05 11:11:27",
            "creation_date": "2020-10-05 11:11:27",
            "updated_date": "2020-10-05 11:11:27",
            "user": "[email protected]",
            "user_type": "individual"
        },
        {
            "productname": "abc cream",
            "quantity": "1",
            "unit": "Peice",
            "description": "abc 100 gram",
            "preferred_brand": "abccream",

            "creation_date": "2020-10-05 11:11:27",
            "updated_date": "2020-10-05 11:11:27",
            "user": "[email protected]",
            "user_type": "individual"
        }
    ]
}

It looks like you may be confused as to when commands are run. In your example, you are calling the get method before the GUI has a chance to be displayed on the screen (which happens after you call mainloop.

Try adding a button that calls the get method. This is much easier if you write your application as a class. For example:

import tkinter as tk

class SampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.entry = tk.Entry(self)
        self.button = tk.Button(self, text="Get", command=self.on_button)
        self.button.pack()
        self.entry.pack()

    def on_button(self):
        print(self.entry.get())

app = SampleApp()
app.mainloop()

Run the program, type into the entry widget, then click on the button.

For me none of the packages mentioned above did help.

I finally managed to install lxml after running:

sudo apt-get install python3.5-dev

Currently from MySQL 8 you can set the following to a DATE column:

In MySQL Workbench, in the Default field next to the column, write: (curdate())

If you put just curdate() it will fail. You need the extra ( and ) at the beginning and end.

Here's a Swift 3.2+ alternative that avoids unnecessary string manipulation. In this case, the maximum length is 10:

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    let text = textField.text ?? ""

    return text.count - range.length + string.count <= 10
}

Here is a piece of code to do so:

def(StringChallenge(str1)):

#str1 = str1[1:-1]
h1 = 0
h2 = 0
m1 = 0
m2 = 0

def time_dif(h1,m1,h2,m2):
    if(h1 == h2):
        return m2-m1
    else:
        return ((h2-h1-1)*60 + (60-m1) + m2)
count_min = 0

if str1[1] == ':':
    h1=int(str1[:1])
    m1=int(str1[2:4])
else:
    h1=int(str1[:2])
    m1=int(str1[3:5])

if str1[-7] == '-':
    h2=int(str1[-6])
    m2=int(str1[-4:-2])
else:
    h2=int(str1[-7:-5])
    m2=int(str1[-4:-2])

if h1 == 12:
    h1 = 0
if h2 == 12:
    h2 = 0

if "am" in str1[:8]:
    flag1 = 0
else:
    flag1= 1

if "am" in str1[7:]:
    flag2 = 0
else:
    flag2 = 1

if flag1 == flag2:
    if h2 > h1 or (h2 == h1 and m2 >= m1):
        count_min += time_dif(h1,m1,h2,m2)
    else:
        count_min += 1440 - time_dif(h2,m2,h1,m1)
else:
    count_min += (12-h1-1)*60
    count_min += (60 - m1)
    count_min += (h2*60)+m2


return count_min

I encountered the same problem. The easiest thing is to install the free Visual Studio Community 2015 as answered in this question Is MFC only available with Visual Studio, and not Visual C++ Express?

Few years later, I second Bobby Jack's observation that last 24 hrs is not today!!! And I am surprised that the answer was so much upvoted...

To compare if a certain date is less, equal or greater than another, first you need to turn them "down" to beginning of the day. In other words, make sure that you're talking about same 00:00:00 time in both dates. This can be simply and elegantly done as:

strtotime("today") <=> strtotime($var)

if $var has the time part on 00:00:00 like the OP specified.

Replace <=> with whatever you need (or keep it like this in php 7)

Also, obviously, we're talking about same timezone for both. For list of supported TimeZones

Using above mentioned comments and solutions, I am storing all the query parameters using Map<String, Object> where Objects either can be string or Set<String>. The solution is given below. It is recommended to use some kind of url validator to validate the url first and then call convertQueryStringToMap method.

private static final String DEFAULT_ENCODING_SCHEME = "UTF-8";

public static Map<String, Object> convertQueryStringToMap(String url) throws UnsupportedEncodingException, URISyntaxException {
    List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), DEFAULT_ENCODING_SCHEME);
    Map<String, Object> queryStringMap = new HashMap<>();
    for(NameValuePair param : params){
        queryStringMap.put(param.getName(), handleMultiValuedQueryParam(queryStringMap, param.getName(), param.getValue()));
    }
    return queryStringMap;
}

private static Object handleMultiValuedQueryParam(Map responseMap, String key, String value) {
    if (!responseMap.containsKey(key)) {
        return value.contains(",") ? new HashSet<String>(Arrays.asList(value.split(","))) : value;
    } else {
        Set<String> queryValueSet = responseMap.get(key) instanceof Set ? (Set<String>) responseMap.get(key) : new HashSet<String>();
        if (value.contains(",")) {
            queryValueSet.addAll(Arrays.asList(value.split(",")));
        } else {
            queryValueSet.add(value);
        }
        return queryValueSet;
    }
}

As Vinay Kumar pointed out that it will not update global installed Angular CLI. To update it globally just use following commands:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Note if you want to update existing project you have to modify existing project, you should change package.json inside your project.

There are no breaking changes in Angular itself but they are in RxJS, so don't forget to use rxjs-compat library to work with legacy code.

  npm install --save rxjs-compat  

I wrote a good article about installation/updating Angular CLI http://bmnteam.com/angular-cli-installation/

1. I save the diff of the current directory (including uncommitted files) against the current HEAD.
2. Then you can transport the save.patch file to wherever (including binary files).
3. On your target machine, apply the patch using git apply <file>

Note: it diff's the currently staged files too.

$ git diff --binary --staged HEAD > save.patch
$ git reset --hard
$ <transport it>
$ git apply save.patch

Replace this:

int hour = 23 - [[now dateWithCalendarFormat:nil timeZone:nil] hourOfDay];
int min = 59 - [[now dateWithCalendarFormat:nil timeZone:nil] minuteOfHour];
int sec = 59 - [[now dateWithCalendarFormat:nil timeZone:nil] secondOfMinute];
countdownLabel.text = [NSString stringWithFormat:@"%02d:%02d:%02d", hour, min,sec];

With this:

NSDate* now = [NSDate date];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponents = [gregorian components:(NSHourCalendarUnit  | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:now];
NSInteger hour = [dateComponents hour];
NSInteger minute = [dateComponents minute];
NSInteger second = [dateComponents second];
[gregorian release];
countdownLabel.text = [NSString stringWithFormat:@"%02d:%02d:%02d", hour, minute, second];

$ds.Tables["tblTest"] is an object that you can manipulate just like any other Powershell object:

$ds.Tables["tblTest"] | foreach {
    write-host 'Name value is : $_.name
    write-host 'Path value is : $_.path
}

The best way to go about it would be to get a SynchronizationContext from the UI thread and use it. This class abstracts marshalling calls to other threads, and makes testing easier (in contrast to using WPF's Dispatcher directly). For example:

class MyViewModel
{
    private readonly SynchronizationContext _syncContext;

    public MyViewModel()
    {
        // we assume this ctor is called from the UI thread!
        _syncContext = SynchronizationContext.Current;
    }

    // ...

    private void watcher_Changed(object sender, FileSystemEventArgs e)
    {
         _syncContext.Post(o => DGAddRow(crp.Protocol, ft), null);
    }
}

Since @OscarLopez and I have different opinions on what the second largest means, I'll post the code according to my interpretation and in line with the first algorithm provided by the questioner.

def second_largest(numbers):
    count = 0
    m1 = m2 = float('-inf')
    for x in numbers:
        count += 1
        if x > m2:
            if x >= m1:
                m1, m2 = x, m1            
            else:
                m2 = x
    return m2 if count >= 2 else None

(Note: Negative infinity is used here instead of None since None has different sorting behavior in Python 2 and 3 – see Python - Find second smallest number; a check for the number of elements in numbers makes sure that negative infinity won't be returned when the actual answer is undefined.)

If the maximum occurs multiple times, it may be the second largest as well. Another thing about this approach is that it works correctly if there are less than two elements; then there is no second largest.

Running the same tests:

second_largest([20,67,3,2.6,7,74,2.8,90.8,52.8,4,3,2,5,7])
=> 74
second_largest([1,1,1,1,1,2])
=> 1
second_largest([2,2,2,2,2,1])
=> 2
second_largest([10,7,10])
=> 10
second_largest([1,1,1,1,1,1])
=> 1
second_largest([1])
=> None
second_largest([])
=> None

Update

I restructured the conditionals to drastically improve performance; almost by a 100% in my testing on random numbers. The reason for this is that in the original version, the elif was always evaluated in the likely event that the next number is not the largest in the list. In other words, for practically every number in the list, two comparisons were made, whereas one comparison mostly suffices – if the number is not larger than the second largest, it's not larger than the largest either.

See What is the maximum length of a URL in different browsers?

The length of the url can't be changed in PHP. The linked question is about the URL size limit, you will find what you want.

Here is another way, without the need for nesting the repeaters.

From the Angularjs docs:

It is possible to get ngRepeat to iterate over the properties of an object using the following syntax:

<div ng-repeat="(key, value) in steps"> {{key}} : {{value}} </div>

http://constc.blogspot.com/2008/07/undeclared-undefined-null-in-javascript.html

Depends on how specific you want the test to be. You could maybe get away with

if(page_name){ string += "&page_name=" + page_name; }

You can use strptime in the datetime package of Python:

>>> import datetime
>>> datetime.datetime.strptime('24052010', "%d%m%Y").date()
datetime.date(2010, 5, 24)

If you are looking for 1st Number with decimal as string has correct decimal places, you may try regexp_substr function like this:

regexp_substr('stack12.345overflow', '\.*[[:digit:]]+\.*[[:digit:]]*')

In layman terms:- JDK = JRE + Development/debugging tools, where JDK is our complete package to work with Java, from creating compiling till running it.On the other hand JRE is just of running of code(Byte Code).

Note:- Whether we are installing JDK or JRE, JVM would come bundled with both the packages and JVM is the part where JIT compiler converts the byte code into the machine specific code.

Just read the article on JDK,JRE ,JVM and JIT

First of all check to see if your PHP installation supports CLI. Type: php -v. You can execute PHP from the command line in 2 ways:

1. php yourfile.php
2. php -r 'print("Hello world");'

I use both PuTTY and Bitvise SSH Client. PuTTY handles screen sessions better, but Bitvise automatically opens up a SFTP window so you can transfer files just like you would with an FTP client.

How about this?

I prefer using PHPMailer script to send emails from localhost as it lets me use my Gmail account as SMTP. You can find the PHPMailer from http://phpmailer.worxware.com/ . Help regarding how to use gmail as SMTP or any other SMTP can be found at http://www.mittalpatel.co.in/php_send_mail_from_localhost_using_gmail_smtp . Hope this helps!

How about:

if (regexMatcher.find()) {
    resultString = regexMatcher.replaceAll(
            String.valueOf(3 * Integer.parseInt(regexMatcher.group(1))));
}

To get the first match, use #find(). After that, you can use #group(1) to refer to this first match, and replace all matches by the first maches value multiplied by 3.

And in case you want to replace each match with that match's value multiplied by 3:

    Pattern p = Pattern.compile("(\\d{1,2})");
    Matcher m = p.matcher("12 54 1 65");
    StringBuffer s = new StringBuffer();
    while (m.find())
        m.appendReplacement(s, String.valueOf(3 * Integer.parseInt(m.group(1))));
    System.out.println(s.toString());

You may want to look through Matcher's documentation, where this and a lot more stuff is covered in detail.

I was in your shoes for a while and finally ended up using node.js, because it can do hybrid solutions like having web and socket server in one. So php backend can submit requests thru http to node web server and then broadcast it with websocket. Very efficiant way to go.

I stumbled upon this problem during attempt to dockerise Avahi which needs to be aware of its public IP to function properly. Assigning static IP to the container is tricky due to lack of support for static IP assignment in Docker.

This article describes technique how to assign static IP to the container on Debian:

1. Docker service should be started with DOCKER_OPTS="--bridge=br0 --ip-masq=false --iptables=false". I assume that br0 bridge is already configured.

2. Container should be started with --cap-add=NET_ADMIN --net=bridge

3. Inside container pre-up ip addr flush dev eth0 in /etc/network/interfaces can be used to dismiss IP address assigned by Docker as in following example:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
    pre-up ip addr flush dev eth0
    address 192.168.0.249
    netmask 255.255.255.0
    gateway 192.168.0.1

4. Container's entry script should begin with /etc/init.d/networking start. Also entry script needs to edit or populate /etc/hosts file in order to remove references to Docker-assigned IP.

Both the verifyNoMoreInteractions() and verifyZeroInteractions() method internally have the same implementation as:

public static transient void verifyNoMoreInteractions(Object mocks[])
{
    MOCKITO_CORE.verifyNoMoreInteractions(mocks);
}

public static transient void verifyZeroInteractions(Object mocks[])
{
    MOCKITO_CORE.verifyNoMoreInteractions(mocks);
}

so we can use any one of them on mock object or array of mock objects to check that no methods have been called using mock objects.

I think you lack to pass Connection object to your command object. and it is much better if you will use command and parameters for that.

using (SqlConnection connection = new SqlConnection("ConnectionStringHere"))
{
    using (SqlCommand command = new SqlCommand())
    {
        command.Connection = connection;            // <== lacking
        command.CommandType = CommandType.Text;
        command.CommandText = "INSERT into tbl_staff (staffName, userID, idDepartment) VALUES (@staffName, @userID, @idDepart)";
        command.Parameters.AddWithValue("@staffName", name);
        command.Parameters.AddWithValue("@userID", userId);
        command.Parameters.AddWithValue("@idDepart", idDepart);

        try
        {
            connection.Open();
            int recordsAffected = command.ExecuteNonQuery();
        }
        catch(SqlException)
        {
            // error here
        }
        finally
        {
            connection.Close();
        }
    }
}

I have added app.UseStaticFiles(); this code in my startup.cs than it is fixed

var myVar = $("#start").find('myClass').val();

needs to be

var myVar = $("#start").find('.myClass').val();

Remember the CSS selector rules require "." if selecting by class name. The absence of "." is interpreted to mean searching for <myclass></myclass>.

Consider Moshi's JsonWriter class (source). It has a wonderful API and it reduces copying to a minimum, everything is nicely streamed to the OutputStream.

OutputStream os = ...;
JsonWriter json = new JsonWriter(Okio.sink(os));
json
  .beginObject()
  .name("id").value(userID)
  .name("type").value(methodn)
  ...
  .endObject();

In my opinion, uniqueidentifier / GUID is neither a varchar nor an nvarchar but a char(36). Therefore I use:

CAST(xyz AS char(36))

Update: req.param() is now deprecated, so going forward do not use this answer.

Your answer is the preferred way to do it, however I thought I'd point out that you can also access url, post, and route parameters all with req.param(parameterName, defaultValue).

In your case:

var color = req.param('color');

From the express guide:

lookup is performed in the following order:

• req.params
• req.body
• req.query

Note the guide does state the following:

Direct access to req.body, req.params, and req.query should be favoured for clarity - unless you truly accept input from each object.

However in practice I've actually found req.param() to be clear enough and makes certain types of refactoring easier.

Not sure why this isn't implemented directly in R, but this answer is essentially the same as Andrii's and Wordsforthewise, I just turned into a function for the sake of convenience if somebody uses it a lot like me.

r2_general <-function(preds,actual){ 
  return(1- sum((preds - actual) ^ 2)/sum((actual - mean(actual))^2))
}

I found a good example of what you need in this link.

import javax.swing.JFileChooser;

public class Main {
  public static void main(String s[]) {
    JFileChooser chooser = new JFileChooser();
    chooser.setCurrentDirectory(new java.io.File("."));
    chooser.setDialogTitle("choosertitle");
    chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    chooser.setAcceptAllFileFilterUsed(false);

    if (chooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION) {
      System.out.println("getCurrentDirectory(): " + chooser.getCurrentDirectory());
      System.out.println("getSelectedFile() : " + chooser.getSelectedFile());
    } else {
      System.out.println("No Selection ");
    }
  }
}

I use "docker run" (not "docker exec"), and I'm in a restricted zone where we cannot install an editor. But I have an editor on the Docker host.

My workaround is: Bind mount a volume from the Docker host to the container (https://docs.docker.com/engine/reference/run/#/volume-shared-filesystems), and edit the file outside the container. It looks like this:

docker run -v /outside/dir:/container/dir

This is mostly for experimenting, and later I'd change the file when building the image.

The '\r' stands for "Carriage Return" - it's a holdover from the days of typewriters and really old printers. The best example is in Windows and other DOSsy OSes, where a newline is given as "\r\n". These are the instructions sent to an old printer to start a new line: first move the print head back to the beginning, then go down one.

Different OSes will use other newline sequences. Linux and OSX just use '\n'. Older Mac OSes just use '\r'. Wikipedia has a more complete list, but those are the important ones.

Hope this helps!

PS: As for why you get that weird output... Perhaps the console is moving the "cursor" back to the beginning of the line, and then overwriting the first bit with spaces or summat.

The way I've done it by using AuthenticatesUsers trait.

\App\Http\Controllers\Auth\LoginController.php

Add this method to that controller:

/**
 * Check user's role and redirect user based on their role
 * @return 
 */
public function authenticated()
{
    if(auth()->user()->hasRole('admin'))
    {
        return redirect('/admin/dashboard');
    } 

    return redirect('/user/dashboard');
}

Add programatically noborder class to specific row to hide it

<style>
     .noborder
      {
        border:none;
      }
    </style>

<table>

    <tr>
       <th>heading1</th>
       <th>heading2</th>
    </tr>


    <tr>
       <td>content1</td>
       <td>content2</td>
    </tr>
    /*no border for this row */
    <tr class="noborder">
       <td>content1</td>
       <td>content2</td>
    </tr>

</table>

I'm doing it this way:

    function f(data,d){
    console.log(d);
    console.log(data);
}
$.ajax({
    url:u,
    success:function(data){ f(data,d);  }
});

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} ); 

with slice():

var a = [1,2,3,4];
var lastEl = a.slice(-1)[0]; // 4
// a is still [1,2,3,4]

with pop();

var a = [1,2,3,4];
var lastEl = a.pop(); // 4
// a is now [1,2,3]

see https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array for more information

You can use css ellipsis; but you have to give fixed width and overflow:hidden: to that element.

<span style="display:block;text-overflow: ellipsis;width: 200px;overflow: hidden; white-space: nowrap;">_x000D_
 Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat._x000D_
 </span>

Try this jobber

String stringy =null;
 byte[] buffer =  new byte[100000];
            for (int i = 0; i < buffer.length; i++) {
            buffer[i] =0;

        }
            stringy =StringUtils.toAsciiString(buffer);

try this

$sql= " INSERT INTO users (username, password) VALUES('test', 'test') ";
mysql_query($sql);
$user_id= mysql_insert_id();
if(!empty($user_id) {

$sql=INSERT INTO profiles (userid, bio, homepage) VALUES($user_id,'Hello world!', 'http://www.stackoverflow.com');
/* or 
 $sql=INSERT INTO profiles (userid, bio, homepage) VALUES(LAST_INSERT_ID(),'Hello   world!', 'http://www.stackoverflow.com'); */
 mysql_query($sql);
};

Git revert only accepts commits

From the docs:

Given one or more existing commits, revert the changes that the related patches introduce ...

myFile is intepretted as a commit - because git revert doesn't accept file paths; only commits

Change one file to match a previous commit

To change one file to match a previous commit - use git checkout

git checkout HEAD~2 myFile

You need to set the g flag to replace globally:

date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')

Otherwise only the first occurrence will be replaced.

OK... I can resond..

Disclaimer: I just had an 18+ hour day (again).. I'm old and forgetfull.. I can't spell.. I have a short attention span so I better respond fast.. :-)

Question:

Is it possible to change the thread principal to an user with no account on the local machine?

Answer:

Yes, you can change a thread principal even if the credentials you are using are not defined locally or are outside the "forest".

I just ran into this problem when trying to connect to an SQL server with NTLM authentication from a service. This call uses the credentials associated with the process meaning that you need either a local account or a domain account to authenticate before you can impersonate. Blah, blah...

But...

Calling LogonUser(..) with the attribute of ????_NEW_CREDENTIALS will return a security token without trying to authenticate the credentials. Kewl.. Don't have to define the account within the "forest". Once you have the token you might have to call DuplicateToken() with the option to enable impersonation resulting in a new token. Now call SetThreadToken( NULL, token ); (It might be &token?).. A call to ImpersonateLoggedonUser( token ); might be required, but I don't think so. Look it up..

Do what you need to do..

Call RevertToSelf() if you called ImpersonateLoggedonUser() then SetThreadToken( NULL, NULL ); (I think... look it up), and then CloseHandle() on the created handles..

No promises but this worked for me... This is off the top of my head (like my hair) and I can't spell!!!

There's a good article on predicates here, although it's from the .NET2 era, so there's no mention of lambda expressions in there.

for those searching for an alternative to $result = $stmt->get_result() I've made this function which allows you to mimic the $result->fetch_assoc() but using directly the stmt object:

function fetchAssocStatement($stmt)
{
    if($stmt->num_rows>0)
    {
        $result = array();
        $md = $stmt->result_metadata();
        $params = array();
        while($field = $md->fetch_field()) {
            $params[] = &$result[$field->name];
        }
        call_user_func_array(array($stmt, 'bind_result'), $params);
        if($stmt->fetch())
            return $result;
    }

    return null;
}

as you can see it creates an array and fetches it with the row data, since it uses $stmt->fetch() internally, you can call it just as you would call mysqli_result::fetch_assoc (just be sure that the $stmt object is open and result is stored):

//mysqliConnection is your mysqli connection object
if($stmt = $mysqli_connection->prepare($query))
{
    $stmt->execute();
    $stmt->store_result();

    while($assoc_array = fetchAssocStatement($stmt))
    {
        //do your magic
    }

    $stmt->close();
}

The trick is to add environment variables to sudoers file via sudo visudo command and add these lines:

Defaults env_keep += "ftp_proxy http_proxy https_proxy no_proxy"

taken from ArchLinux wiki.

For Ubuntu 14, you need to specify in separate lines as it returns the errors for multi-variable lines:

Defaults  env_keep += "http_proxy"
Defaults  env_keep += "https_proxy"
Defaults  env_keep += "HTTP_PROXY"
Defaults  env_keep += "HTTPS_PROXY"

If you're actually ony interested in the latest revision files of a directory, Github lets you download a repository as Zip file, which does not contain history. So downloading is very much faster.

I'm preferred my own way to synchronize all Visual Studio Code extensions between laptops, using .dotfiles and small script to perform updates automatically. This way helps me every time when I want to install all extensions I have without any single mouse activity in Visual Studio Code after installing (via Homebrew).

So I just write each new added extension to .txt file stored at my .dotfiles folder. After that I pull master branch on another laptop to get up-to-date file with all extensions.

Using the script, which Big Rich had written before, with one more change, I can totally synchronise all extensions almost automatically.

Script

cat dart-extensions.txt | xargs -L 1 code --install-extension

And also there is one more way to automate that process. Here you can add a script which looks up a Visual Studio Code extension in realtime and each time when you take a diff between the code --list-extensions command and your .txt file in .dotfiles, you can easily update your file and push it to your remote repository.

Go to the folder in which you have Node and NPM (such as C:\Program Files (x86)\nodejs\) and type the following:

> set path=%PATH%;%CD%
> setx path "%PATH%"

From http://www.hacksparrow.com/install-node-js-and-npm-on-windows.html

In my case I was doing something like the following:

if (a.someField == null) {
    return 1;
}

if (b.someField == null) {
    return -1;
}

if (a.someField.equals(b.someField)) {
    return a.someOtherField.compareTo(b.someOtherField);
}

return a.someField.compareTo(b.someField);

What I forgot to check was when both a.someField and b.someField are null.

FWIW, Codegear C++Builder doesn't destruct in the expected order according to the standard.

C:\> sample.exe 1 2
Created in foo
Created in if
Destroyed in foo
Destroyed in if

... which is another reason not to rely on the destruction order!

JSON : It is mainly used to exchange data to/from the server. Before sending the JSON object to the server, it has to be a string.

JSON.stringify() //Converts the JSON object into the string representation.
var jsonData={"Name":"ABC","Dept":"Software"};// It is a JSON object
var jsonString=JSON.stringify(jsonData);// It is a string representation of the object
// jsonString === '{"Name":"ABC","Dept":"Software"}'; is true

It also converts the Javascript array into string

var arrayObject=["ABC","Software"];// It is array object
var arrString=JSON.stringify(array);// It is string representation of the array (object)
// arrString === '["ABC","Software"]'; is true 

When we received the JSON data from the server, the data would be the string format.Hence we convert the string into JSON object.

JSON.parse() //To convert the string into JSON object.
var data='{ "name":"ABC", "Dept":"Software"}'// it is a string (even though it looks like an object)
var JsonData= JSON.parse(data);// It is a JSON Object representation of the string.
// JsonData === { "name":"ABC", "Dept":"Software"}; is true

I did some modification to the above code to make it work faster if you are searching in only one owner. You just have to change the 3 variables v_owner, v_data_type and v_search_string to fit what you are searching for.

SET SERVEROUTPUT ON SIZE 100000

DECLARE
  match_count INTEGER;
-- Type the owner of the tables you are looking at
  v_owner VARCHAR2(255) :='ENTER_USERNAME_HERE';

-- Type the data type you are look at (in CAPITAL)
-- VARCHAR2, NUMBER, etc.
  v_data_type VARCHAR2(255) :='VARCHAR2';

-- Type the string you are looking at
  v_search_string VARCHAR2(4000) :='string to search here...';

BEGIN
  FOR t IN (SELECT table_name, column_name FROM all_tab_cols where owner=v_owner and data_type = v_data_type) LOOP

    EXECUTE IMMEDIATE 
    'SELECT COUNT(*) FROM '||t.table_name||' WHERE '||t.column_name||' = :1'
    INTO match_count
    USING v_search_string;

    IF match_count > 0 THEN
      dbms_output.put_line( t.table_name ||' '||t.column_name||' '||match_count );
    END IF;

  END LOOP;

Open eclipse.ini in the installation directory, and observe the line with text:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519 then it is 64 bit.

If it would be plugins/org.eclipse.equinox.launcher.win32.win32.x86_32_1.0.200.v20090519 then it is 32 bit.

You can use (keyup) or (change) events, see example below:

<input (keyup)="change($event)">

Or

<input (change)="change($event)">

in Component:

change(event) {console.log(event.target.value);}

here I have something, through which you can count the number of occurrence of a particular number: according to your code

count_of_zero=list(y[y==0]).count(0)

print(count_of_zero)

// according to the match there will be boolean values and according to True value the number 0 will be return

Usually sqlcmd comes with bcp utility (as part of mssql-tools) which exports into CSV by default.

Usage:

bcp {dbtable | query} {in | out | queryout | format} datafile

For example:

bcp.exe MyTable out data.csv

To dump all tables into corresponding CSV files, here is the Bash script:

#!/usr/bin/env bash
# Script to dump all tables from SQL Server into CSV files via bcp.
# @file: bcp-dump.sh
server="sql.example.com" # Change this.
user="USER" # Change this.
pass="PASS" # Change this.
dbname="DBNAME" # Change this.

It's just PHP, not HTML.

It parses all HTML fields with [] into an array.

So you can have

<input type="checkbox" name="food[]" value="apple" />
<input type="checkbox" name="food[]" value="pear" />

and when submitted, PHP will make $_POST['food'] an array, and you can access its elements like so:

echo $_POST['food'][0]; // would output first checkbox selected

or to see all values selected:

foreach( $_POST['food'] as $value ) {
    print $value;
}

Anyhow, don't think there is a specific name for it

I was facing the same issue. After many tries below solution worked for me.

Before installing VC++ install your windows updates. 1. Go to Start - Control Panel - Windows Update 2. Check for the updates. 3. Install all updates. 4. Restart your system.

After that you can follow the below steps.

Download the Visual C++ Redistributable 2015

Visual C++ Redistributable for Visual Studio 2015 (64-bit)

Visual C++ Redistributable for Visual Studio 2015 (32-bit)

(Reinstal if already installed) then restart your computer or use windows updates for download auto.

For link download https://www.microsoft.com/de-de/download/details.aspx?id=48145.

I have been using the ArrayListAdapter to dynamically put in the entries into the respective fields ; This can be useful , for future queries

 AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();

And then , you can fetch any arraylist item as below :

arrayListName(info.position);

In your binding configuration, there are four timeout values you can tweak:

<bindings>
  <basicHttpBinding>
    <binding name="IncreasedTimeout"
             sendTimeout="00:25:00">
    </binding>
  </basicHttpBinding>

The most important is the sendTimeout, which says how long the client will wait for a response from your WCF service. You can specify hours:minutes:seconds in your settings - in my sample, I set the timeout to 25 minutes.

The openTimeout as the name implies is the amount of time you're willing to wait when you open the connection to your WCF service. Similarly, the closeTimeout is the amount of time when you close the connection (dispose the client proxy) that you'll wait before an exception is thrown.

The receiveTimeout is a bit like a mirror for the sendTimeout - while the send timeout is the amount of time you'll wait for a response from the server, the receiveTimeout is the amount of time you'll give you client to receive and process the response from the server.

In case you're send back and forth "normal" messages, both can be pretty short - especially the receiveTimeout, since receiving a SOAP message, decrypting, checking and deserializing it should take almost no time. The story is different with streaming - in that case, you might need more time on the client to actually complete the "download" of the stream you get back from the server.

There's also openTimeout, receiveTimeout, and closeTimeout. The MSDN docs on binding gives you more information on what these are for.

To get a serious grip on all the intricasies of WCF, I would strongly recommend you purchase the "Learning WCF" book by Michele Leroux Bustamante:

Learning WCF http://ecx.images-amazon.com/images/I/51GNuqUJq%2BL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg

and you also spend some time watching her 15-part "WCF Top to Bottom" screencast series - highly recommended!

For more advanced topics I recommend that you check out Juwal Lowy's Programming WCF Services book.

Programming WCF http://ecx.images-amazon.com/images/I/41odWcLoGAL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg

 decimal Total = 0;

for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
    Total+= Convert.ToDecimal(dataGridView1.Rows[i].Cells["ColumnName"].Value);
  }

labelName.Text = Total.ToString();

If searching for an element is important, I'd recommend std::set instead of std::vector. Using this:

std::find(vec.begin(), vec.end(), x) runs in O(n) time, but std::set has its own find() member (ie. myset.find(x)) which runs in O(log n) time - that's much more efficient with large numbers of elements

std::set also guarantees all the added elements are unique, which saves you from having to do anything like if not contained then push_back()....

I needed a simple boolean to work with. Because it's undefined of not present, and not false, I use the !! to convert to boolean:

var hasTimer = !!$("#dataTable").data('timer');
if( hasTimer ){ /* ....... */ }

An alternative solution would be using filter:

if( $("#dataTable").filter('[data-timer]').length!==0) { /* ....... */ }

The definition for DTO can be found on Martin Fowler's site. DTOs are used to transfer parameters to methods and as return types. A lot of people use those in the UI, but others inflate domain objects from them.

That can be done with:

foo(*values)

Just use your table inside a div with a class (.table1 for example) and don't set any border for this table in CSS. Then use CSS code for that class.

.table1 {border=1px solid black;}

There may be some file access permission/restriction problems. First check to access the below directory manually, check whether your TARGET_VERSION exists, Then check the android sdk manager.

• sdk/build-tools/{TARGET_VERSION}

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

graph-fs

Install

npm i graph-fs

Use

const {Node} = require("graph-fs");
const directory = new Node("/path/to/directory");

directory.delete(); // <--

'actual code

http://www.bsourcecode.com/codeigniter/codeigniter-select-query/

$query = $this->db->query("select * from tbl_user");

$query = $this->db->select("*");

            $query=$this->db->get();

First, the second is not equivalent to the other two. $#array returns the last index of the array, which is one less than the size of the array.

The other two are virtually the same. You are simply using two different means to create scalar context. It comes down to a question of readability.

I personally prefer the following:

say 0+@array;          # Represent @array as a number

I find it clearer than

say scalar(@array);    # Represent @array as a scalar

and

my $size = @array;
say $size;

The latter looks quite clear alone like this, but I find that the extra line takes away from clarity when part of other code. It's useful for teaching what @array does in scalar context, and maybe if you want to use $size more than once.

If anyone is looking for a VB.Net answer (as I was initially), here it is:

Public Function IsSatisfied() As Expression(Of Func(Of Charity, String, String, Boolean))

Return Function(charity, name, referenceNumber) (String.IsNullOrWhiteSpace(name) Or
                                                         charity.registeredName.ToLower().Contains(name.ToLower()) Or
                                                         charity.alias.ToLower().Contains(name.ToLower()) Or
                                                         charity.charityId.ToLower().Contains(name.ToLower())) And
                                                    (String.IsNullOrEmpty(referenceNumber) Or
                                                     charity.charityReference.ToLower().Contains(referenceNumber.ToLower()))
End Function

yet another go at the same problem - form-container on npm

Just in case you arrived here because you copied a branch name from Github, note that a remote branch is not automatically also a local branch, so a merge will not work and give the "not something we can merge" error.

In that case, you have two options:

git checkout [branchYouWantToMergeInto]
git merge origin/[branchYouWantToMerge]

or

# this creates a local branch
git checkout [branchYouWantToMerge]

git checkout [branchYouWantToMergeInto]
git merge [branchYouWantToMerge]

This is a very round-about way of doing it but if you want to make a histogram where you already know the bin values but dont have the source data, you can use the np.random.randint function to generate the correct number of values within the range of each bin for the hist function to graph, for example:

import numpy as np
import matplotlib.pyplot as plt

data = [np.random.randint(0, 9, *desired y value*), np.random.randint(10, 19, *desired y value*), etc..]
plt.hist(data, histtype='stepfilled', bins=[0, 10, etc..])

as for labels you can align x ticks with bins to get something like this:

#The following will align labels to the center of each bar with bin intervals of 10
plt.xticks([5, 15, etc.. ], ['Label 1', 'Label 2', etc.. ])

I'm tuning into what krtek has written. More specifically solution 1:

Assumptions:

• you've committed one (!) changeset but have not pushed it yet
• you want to modify this changeset (e.g. add, remove or change files and/or the commit message)

Solution:

• use hg rollback to undo the last commit
• commit again with the new changes in place

The rollback really undoes the last operation. Its way of working is quite simple: normal operations in HG will only append to files; this includes a commit. Mercurial keeps track of the file lengths of the last transaction and can therefore completely undo one step by truncating the files back to their old lengths.

Here it is:

s = "123"
try:
  i = int(s)
except ValueError as verr:
  pass # do job to handle: s does not contain anything convertible to int
except Exception as ex:
  pass # do job to handle: Exception occurred while converting to int
