First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

You also seem to have a lack of understanding about how to use layout managers.

Take the time to read through Creating a GUI with Swing and Laying components out in a container

your panel class don't have a constructor that accepts a string

try change

RLS_strid_panel p = new RLS_strid_panel(namn1);

to

RLS_strid_panel p = new RLS_strid_panel();
p.setName1(name1);

The error means you cannot use the local variable mi inside an inner class.

To use a variable inside an inner class you must declare it final. As long as mi is the counter of the loop and final variables cannot be assigned, you must create a workaround to get mi value in a final variable that can be accessed inside inner class:

final Integer innerMi = new Integer(mi);

So your code will be like this:

for (int mi=0; mi<colors.length; mi++){

    String pos = Character.toUpperCase(colors[mi].charAt(0)) + colors[mi].substring(1);
    JMenuItem Jmi =new JMenuItem(pos);
    Jmi.setIcon(new IconA(colors[mi]));

    // workaround:
    final Integer innerMi = new Integer(mi);

    Jmi.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                JMenuItem item = (JMenuItem) e.getSource();
                IconA icon = (IconA) item.getIcon();
                // HERE YOU USE THE FINAL innerMi variable and no errors!!!
                Color kolorIkony = getColour(colors[innerMi]); 
                textArea.setForeground(kolorIkony);
            }
        });

        mnForeground.add(Jmi);
    }
}

With me it worked delete this code:

@Override
    public void onAttach(Context context) {
        super.onAttach(context);
        if (context instanceof OnFragmentInteractionListener) {
            mListener = (OnFragmentInteractionListener) context;
        } else {
            throw new RuntimeException(context.toString()
                    + " must implement OnFragmentInteractionListener");
        }
    }

Ending like this:

@Override
public void onAttach(Context context) {
    super.onAttach(context);
}

It can happen if the JDK version is different.

try this with maven:

<properties>
    <jdk.version>1.8</jdk.version>
</properties>

under build->plugins:

<plugin>

    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
        <source>${jdk.version}</source>
        <target>${jdk.version}</target>
    </configuration>

</plugin>

you can use this code as template please customize it as per your requirement.

DefaultTableModel model = new DefaultTableModel();
List<String> list = new ArrayList<String>();

list.add(textField.getText());
list.add(comboBox.getSelectedItem());

model.addRow(list.toArray());

table.setModel(model);

here DefaultTableModel is used to add rows in JTable, you can get more info here.

Use this Command

if(JButton.getModel().isArmed()){
    //your code here.
    //your code will be only executed if JButton is clicked.
}

Answer is short. But it worked for me. Use the variable name of your button instead of "JButton".

I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:

        <p:pickList id="formPickList" 
                    value="#{mediaDetail.availableMedia}" 
                    converter="MediaPicklistConverter" 
                    widgetVar="formsPicklistWidget" 
                    var="mediaFiles" 
                    itemLabel="#{mediaFiles.mediaTitle}" 
                    itemValue="#{mediaFiles}" >
            <f:facet name="sourceCaption">Available Media</f:facet>
            <f:facet name="targetCaption">Chosen Media</f:facet>
        </p:pickList>

        <p:commandButton id="viewStream_btn" 
                         value="Stream chosen media" 
                         icon="fa fa-download"
                         ajax="true"
                         action="#{mediaDetail.prepareStreams}"                                              
                         update=":streamDialogPanel"
                         oncomplete="PF('streamingDialog').show()"
                         styleClass="ui-priority-primary"
                         style="margin-top:5px" >
            <p:ajax process="formPickList"  />
        </p:commandButton>

The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.

As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.

The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" /> bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.

Happy coding!

At the bottom, I have a general solution to replace lines in a file. But first, here is the answer to the specific question at hand. Helper function:

public static void replaceSelected(String replaceWith, String type) {
    try {
        // input the file content to the StringBuffer "input"
        BufferedReader file = new BufferedReader(new FileReader("notes.txt"));
        StringBuffer inputBuffer = new StringBuffer();
        String line;

        while ((line = file.readLine()) != null) {
            inputBuffer.append(line);
            inputBuffer.append('\n');
        }
        file.close();
        String inputStr = inputBuffer.toString();

        System.out.println(inputStr); // display the original file for debugging

        // logic to replace lines in the string (could use regex here to be generic)
        if (type.equals("0")) {
            inputStr = inputStr.replace(replaceWith + "1", replaceWith + "0"); 
        } else if (type.equals("1")) {
            inputStr = inputStr.replace(replaceWith + "0", replaceWith + "1");
        }

        // display the new file for debugging
        System.out.println("----------------------------------\n" + inputStr);

        // write the new string with the replaced line OVER the same file
        FileOutputStream fileOut = new FileOutputStream("notes.txt");
        fileOut.write(inputStr.getBytes());
        fileOut.close();

    } catch (Exception e) {
        System.out.println("Problem reading file.");
    }
}

Then call it:

public static void main(String[] args) {
    replaceSelected("Do the dishes", "1");   
}

Original Text File Content:

Do the dishes0
Feed the dog0
Cleaned my room1

Output:

Do the dishes0
Feed the dog0
Cleaned my room1
----------------------------------
Do the dishes1
Feed the dog0
Cleaned my room1

New text file content:

Do the dishes1
Feed the dog0
Cleaned my room1

And as a note, if the text file was:

Do the dishes1
Feed the dog0
Cleaned my room1

and you used the method replaceSelected("Do the dishes", "1");, it would just not change the file.

Since this question is pretty specific, I'll add a more general solution here for future readers (based on the title).

// read file one line at a time
// replace line as you read the file and store updated lines in StringBuffer
// overwrite the file with the new lines
public static void replaceLines() {
    try {
        // input the (modified) file content to the StringBuffer "input"
        BufferedReader file = new BufferedReader(new FileReader("notes.txt"));
        StringBuffer inputBuffer = new StringBuffer();
        String line;

        while ((line = file.readLine()) != null) {
            line = ... // replace the line here
            inputBuffer.append(line);
            inputBuffer.append('\n');
        }
        file.close();

        // write the new string with the replaced line OVER the same file
        FileOutputStream fileOut = new FileOutputStream("notes.txt");
        fileOut.write(inputBuffer.toString().getBytes());
        fileOut.close();

    } catch (Exception e) {
        System.out.println("Problem reading file.");
    }
}

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

In the ActionListener Class you can simply add

public void actionPerformed(ActionEvent event) {
    if (event.getSource()==textField){
        textButton.doClick();
    }
    else if (event.getSource()==textButton) {
        //do something
    }
}

Sorting the array is unnecessary and inefficient. There's a variation of the QuickSort (QuickSelect) algorithm which has an average run time of O(n); if you sort first, you're down to O(n log n). It actually finds the nth smallest item in a list; for a median, you just use n = half the list length. Let's call it quickNth (list, n).

The concept is that to find the nth smallest, choose a 'pivot' value. (Exactly how you choose it isn't critical; if you know the data will be thoroughly random, you can take the first item on the list.)

Split the original list into three smaller lists:

• One with values smaller than the pivot.
• One with values equal to the pivot.
• And one with values greater than the pivot.

You then have three cases:

1. The "smaller" list has >= n items. In that case, you know that the nth smallest is in that list. Return quickNth(smaller, n).
2. The smaller list has < n items, but the sum of the lengths of the smaller and equal lists have >= n items. In this case, the nth is equal to any item in the "equal" list; you're done.
3. n is greater than the sum of the lengths of the smaller and equal lists. In that case, you can essentially skip over those two, and adjust n accordingly. Return quickNth(greater, n - length(smaller) - length(equal)).

Done.

If you're not sure that the data is thoroughly random, you need to be more sophisticated about choosing the pivot. Taking the median of the first value in the list, the last value in the list, and the one midway between the two works pretty well.

If you're very unlucky with your choice of pivots, and you always choose the smallest or highest value as your pivot, this takes O(n^2) time; that's bad. But, it's also very unlikely if you choose your pivot with a decent algorithm.

Sample code:

import java.util.*;

public class Utility {
   /****************
   * @param coll an ArrayList of Comparable objects
   * @return the median of coll
   *****************/
   
   public static <T extends Number> double median(ArrayList<T> coll, Comparator<T> comp) {
      double result;
      int n = coll.size()/2;
      
      if (coll.size() % 2 == 0)  // even number of items; find the middle two and average them
         result = (nth(coll, n-1, comp).doubleValue() + nth(coll, n, comp).doubleValue()) / 2.0;
      else                      // odd number of items; return the one in the middle
         result = nth(coll, n, comp).doubleValue();
         
      return result;
   } // median(coll)
   
   

   /*****************
   * @param coll a collection of Comparable objects
   * @param n  the position of the desired object, using the ordering defined on the list elements
   * @return the nth smallest object
   *******************/
   
   public static <T> T nth(ArrayList<T> coll, int n, Comparator<T> comp) {
      T result, pivot;
      ArrayList<T> underPivot = new ArrayList<>(), overPivot = new ArrayList<>(), equalPivot = new ArrayList<>();
      
      // choosing a pivot is a whole topic in itself.
      // this implementation uses the simple strategy of grabbing something from the middle of the ArrayList.
      
      pivot = coll.get(n/2);
      
      // split coll into 3 lists based on comparison with the pivot
      
      for (T obj : coll) {
         int order = comp.compare(obj, pivot);
         
         if (order < 0)        // obj < pivot
            underPivot.add(obj);
         else if (order > 0)   // obj > pivot
            overPivot.add(obj);
         else                  // obj = pivot
            equalPivot.add(obj);
      } // for each obj in coll
      
      // recurse on the appropriate list
      
      if (n < underPivot.size())
         result = nth(underPivot, n, comp);
      else if (n < underPivot.size() + equalPivot.size()) // equal to pivot; just return it
         result = pivot;
      else  // everything in underPivot and equalPivot is too small.  Adjust n accordingly in the recursion.
         result = nth(overPivot, n - underPivot.size() - equalPivot.size(), comp);
         
      return result;
   } // nth(coll, n)

The difference is that ActionEvent is fired when the action is performed on the JCheckBox that is its state is changed either by clicking on it with the mouse or with a space bar or a mnemonic. It does not really listen to change events whether the JCheckBox is selected or deselected.

For instance, if JCheckBox c1 (say) is added to a ButtonGroup. Changing the state of other JCheckBoxes in the ButtonGroup will not fire an ActionEvent on other JCheckBox, instead an ItemEvent is fired.

Final words: An ItemEvent is fired even when the user deselects a check box by selecting another JCheckBox (when in a ButtonGroup), however ActionEvent is not generated like that instead ActionEvent only listens whether an action is performed on the JCheckBox (to which the ActionListener is registered only) or not. It does not know about ButtonGroup and all other selection/deselection stuff.

I Solved this problem adding @Cascade to the @ManyToOne attribute.

import org.hibernate.annotations.Cascade;
import org.hibernate.annotations.CascadeType;

@ManyToOne
@JoinColumn(name="BLOODGRUPID")
@Cascade({CascadeType.MERGE, CascadeType.SAVE_UPDATE})
private Bloodgroup bloodgroup;

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

When the callee throws an exception i.e. void showfile() throws java.io.IOException the caller should handle it or throw it again.

And also learn naming conventions. A class name should start with a capital letter.

It's because the tab is a naming container aswell... your update should be update="Search:insTable:display" What you can do aswell is just place your dialog outside the form and still inside the tab then it would be: update="Search:display"

I want to offer an alternate solution for perhaps a slightly different case, since many of my searches for answers kept leading me to this thread.

My case - I'm creating/adding pages dynamically and sliding them into a ViewPager, but when rotated (onConfigurationChange) I end up with a new page because of course OnCreate is called again. But I want to keep reference to all the pages that were created prior to the rotation.

Problem - I don't have unique identifiers for each fragment I create, so the only way to reference was to somehow store references in an Array to be restored after the rotation/configuration change.

Workaround - The key concept was to have the Activity (which displays the Fragments) also manage the array of references to existing Fragments, since this activity can utilize Bundles in onSaveInstanceState

public class MainActivity extends FragmentActivity

So within this Activity, I declare a private member to track the open pages

private List<Fragment> retainedPages = new ArrayList<Fragment>();

This is updated everytime onSaveInstanceState is called and restored in onCreate

@Override
protected void onSaveInstanceState(Bundle outState) {
    retainedPages = _adapter.exportList();
    outState.putSerializable("retainedPages", (Serializable) retainedPages);
    super.onSaveInstanceState(outState);
}

...so once it's stored, it can be retrieved...

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (savedInstanceState != null) {
        retainedPages = (List<Fragment>) savedInstanceState.getSerializable("retainedPages");
    }
    _mViewPager = (CustomViewPager) findViewById(R.id.viewPager);
    _adapter = new ViewPagerAdapter(getApplicationContext(), getSupportFragmentManager());
    if (retainedPages.size() > 0) {
        _adapter.importList(retainedPages);
    }
    _mViewPager.setAdapter(_adapter);
    _mViewPager.setCurrentItem(_adapter.getCount()-1);
}

These were the necessary changes to the main activity, and so I needed the members and methods within my FragmentPagerAdapter for this to work, so within

public class ViewPagerAdapter extends FragmentPagerAdapter

an identical construct (as shown above in MainActivity )

private List<Fragment> _pages = new ArrayList<Fragment>();

and this syncing (as used above in onSaveInstanceState) is supported specifically by the methods

public List<Fragment> exportList() {
    return _pages;
}

public void importList(List<Fragment> savedPages) {
    _pages = savedPages;
}

And then finally, in the fragment class

public class CustomFragment extends Fragment

in order for all this to work, there were two changes, first

public class CustomFragment extends Fragment implements Serializable

and then adding this to onCreate so Fragments aren't destroyed

setRetainInstance(true);

I'm still in the process of wrapping my head around Fragments and Android life cycle, so caveat here is there may be redundancies/inefficiencies in this method. But it works for me and I hope might be helpful for others with cases similar to mine.

Rather than using booleans, why not just set the button to false when its clicked, so you do that in your actionPerformed method. Its more efficient..

if (command.equals("w"))
{
    FileConverter fc = new FileConverter();
    btnConvertDocuments.setEnabled(false);
}

The first problem is that button1 is a local variable of the main method, so the actionPerformed method doesn't have access to it.

The second problem is that the ActionListener interface is implemented by the class calc, but no instance of this class is created in the main method.

The usual way to do what you want is to create an instance of calc and make button1 a field of the calc class.

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

the getText method returns a String, while the setText receives a String, so you can write it like label1.setText(nameField.getText()); in your listener.

Thanks to this site by Mkyong, the only solution that actually worked for us to pass a parameter was this

<h:commandLink action="#{user.editAction}">
    <f:param name="myId" value="#{param.id}" />
</h:commandLink>

with

public String editAction() {

  Map<String,String> params = 
            FacesContext.getExternalContext().getRequestParameterMap();
  String idString = params.get("myId");
  long id = Long.parseLong(idString);
  ...
}

Technically, that you cannot pass to the method itself directly, but to the JSF request parameter map.

Somewhere you have to keep track of what button had been pressed. When things happen, you need to store something in a variable so you can recall the information or it's gone forever.

When someone pressed one of the operator buttons, don't just let them type in another value. Save the operator symbol, then let them type in another value. You could literally just have a String operator that gets the text of the operator button pressed. Then, when the equals button is pressed, you have to check to see which operator you stored. You could do this with an if/else if/else chain.

So, in your symbol's button press event, store the symbol text in a variable, then, in the = button press event, check to see which symbol is in the variable and act accordingly.

Alternatively, if you feel comfortable enough with enums (looks like you're just starting, so if you're not to that point yet, ignore this), you could have an enumeration of symbols that lets you check symbols easily with a switch.

Assume that foo.jsp is your jsp file. and following code is the button that you want do redirect.

<h:commandButton value="Redirect" action="#{trial.enter }"/>  

And now we'll check the method for directing in your java (service) class

 public String enter() {
            if (userName.equals("xyz") && password.equals("123")) {
                return "enter";
            } else {
                return null;
            }
        } 

and now this is a part of faces-config.xml file

<managed-bean>
        <managed-bean-name>'class_name'</managed-bean-name>
        <managed-bean-class>'package_name'</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
    </managed-bean>


    <navigation-case>
                <from-outcome>enter</from-outcome>
                <to-view-id>/foo.jsp</to-view-id>
                <redirect />
            </navigation-case>

Be aware that when the user modify the field, the DocumentListener can, sometime, receive two events. For instance if the user selects the whole field content, then press a key, you'll receive a removeUpdate (all the content is remove) and an insertUpdate. In your case, I don't think it is a problem but, generally speaking, it is. Unfortunately, it seems there's no way to track the content of the textField without subclassing JTextField. Here is the code of a class that provide a "text" property :

package net.yapbam.gui.widget;

import javax.swing.JTextField;
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.PlainDocument;

/** A JTextField with a property that maps its text.
 * <br>I've found no way to track efficiently the modifications of the text of a JTextField ... so I developed this widget.
 * <br>DocumentListeners are intended to do it, unfortunately, when a text is replace in a field, the listener receive two events:<ol>
 * <li>One when the replaced text is removed.</li>
 * <li>One when the replacing text is inserted</li>
 * </ul>
 * The first event is ... simply absolutely misleading, it corresponds to a value that the text never had.
 * <br>Anoter problem with DocumentListener is that you can't modify the text into it (it throws IllegalStateException).
 * <br><br>Another way was to use KeyListeners ... but some key events are throw a long time (probably the key auto-repeat interval)
 * after the key was released. And others events (for example a click on an OK button) may occurs before the listener is informed of the change.
 * <br><br>This widget guarantees that no "ghost" property change is thrown !

actionListener

Use actionListener if you want have a hook before the real business action get executed, e.g. to log it, and/or to set an additional property (by <f:setPropertyActionListener>), and/or to have access to the component which invoked the action (which is available by ActionEvent argument). So, purely for preparing purposes before the real business action gets invoked.

The actionListener method has by default the following signature:

import javax.faces.event.ActionEvent;
// ...

public void actionListener(ActionEvent event) {
    // ...
}

And it's supposed to be declared as follows, without any method parentheses:

<h:commandXxx ... actionListener="#{bean.actionListener}" />

Note that you can't pass additional arguments by EL 2.2. You can however override the ActionEvent argument altogether by passing and specifying custom argument(s). The following examples are valid:

<h:commandXxx ... actionListener="#{bean.methodWithoutArguments()}" />
<h:commandXxx ... actionListener="#{bean.methodWithOneArgument(arg1)}" />
<h:commandXxx ... actionListener="#{bean.methodWithTwoArguments(arg1, arg2)}" />

public void methodWithoutArguments() {}
public void methodWithOneArgument(Object arg1) {}
public void methodWithTwoArguments(Object arg1, Object arg2) {}

Note the importance of the parentheses in the argumentless method expression. If they were absent, JSF would still expect a method with ActionEvent argument.

If you're on EL 2.2+, then you can declare multiple action listener methods via <f:actionListener binding>.

<h:commandXxx ... actionListener="#{bean.actionListener1}">
    <f:actionListener binding="#{bean.actionListener2()}" />
    <f:actionListener binding="#{bean.actionListener3()}" />
</h:commandXxx>

public void actionListener1(ActionEvent event) {}
public void actionListener2() {}
public void actionListener3() {}

Note the importance of the parentheses in the binding attribute. If they were absent, EL would confusingly throw a javax.el.PropertyNotFoundException: Property 'actionListener1' not found on type com.example.Bean, because the binding attribute is by default interpreted as a value expression, not as a method expression. Adding EL 2.2+ style parentheses transparently turns a value expression into a method expression. See also a.o. Why am I able to bind <f:actionListener> to an arbitrary method if it's not supported by JSF?

action

Use action if you want to execute a business action and if necessary handle navigation. The action method can (thus, not must) return a String which will be used as navigation case outcome (the target view). A return value of null or void will let it return to the same page and keep the current view scope alive. A return value of an empty string or the same view ID will also return to the same page, but recreate the view scope and thus destroy any currently active view scoped beans and, if applicable, recreate them.

The action method can be any valid MethodExpression, also the ones which uses EL 2.2 arguments such as below:

<h:commandXxx value="submit" action="#{bean.edit(item)}" />

With this method:

public void edit(Item item) {
    // ...
}

Note that when your action method solely returns a string, then you can also just specify exactly that string in the action attribute. Thus, this is totally clumsy:

<h:commandLink value="Go to next page" action="#{bean.goToNextpage}" />

With this senseless method returning a hardcoded string:

public String goToNextpage() {
    return "nextpage";
}

Instead, just put that hardcoded string directly in the attribute:

<h:commandLink value="Go to next page" action="nextpage" />

Please note that this in turn indicates a bad design: navigating by POST. This is not user nor SEO friendly. This all is explained in When should I use h:outputLink instead of h:commandLink? and is supposed to be solved as

<h:link value="Go to next page" outcome="nextpage" />

See also How to navigate in JSF? How to make URL reflect current page (and not previous one).

f:ajax listener

Since JSF 2.x there's a third way, the <f:ajax listener>.

<h:commandXxx ...>
    <f:ajax listener="#{bean.ajaxListener}" />
</h:commandXxx>

The ajaxListener method has by default the following signature:

import javax.faces.event.AjaxBehaviorEvent;
// ...

public void ajaxListener(AjaxBehaviorEvent event) {
    // ...
}

In Mojarra, the AjaxBehaviorEvent argument is optional, below works as good.

public void ajaxListener() {
    // ...
}

But in MyFaces, it would throw a MethodNotFoundException. Below works in both JSF implementations when you want to omit the argument.

<h:commandXxx ...>
    <f:ajax execute="@form" listener="#{bean.ajaxListener()}" render="@form" />
</h:commandXxx>

Ajax listeners are not really useful on command components. They are more useful on input and select components <h:inputXxx>/<h:selectXxx>. In command components, just stick to action and/or actionListener for clarity and better self-documenting code. Moreover, like actionListener, the f:ajax listener does not support returning a navigation outcome.

<h:commandXxx ... action="#{bean.action}">
    <f:ajax execute="@form" render="@form" />
</h:commandXxx>

For explanation on execute and render attributes, head to Understanding PrimeFaces process/update and JSF f:ajax execute/render attributes.

Invocation order

The actionListeners are always invoked before the action in the same order as they are been declared in the view and attached to the component. The f:ajax listener is always invoked before any action listener. So, the following example:

<h:commandButton value="submit" actionListener="#{bean.actionListener}" action="#{bean.action}">
    <f:actionListener type="com.example.ActionListenerType" />
    <f:actionListener binding="#{bean.actionListenerBinding()}" />
    <f:setPropertyActionListener target="#{bean.property}" value="some" />
    <f:ajax listener="#{bean.ajaxListener}" />
</h:commandButton>

Will invoke the methods in the following order:

1. Bean#ajaxListener()
2. Bean#actionListener()
3. ActionListenerType#processAction()
4. Bean#actionListenerBinding()
5. Bean#setProperty()
6. Bean#action()

Exception handling

The actionListener supports a special exception: AbortProcessingException. If this exception is thrown from an actionListener method, then JSF will skip any remaining action listeners and the action method and proceed to render response directly. You won't see an error/exception page, JSF will however log it. This will also implicitly be done whenever any other exception is being thrown from an actionListener. So, if you intend to block the page by an error page as result of a business exception, then you should definitely be performing the job in the action method.

If the sole reason to use an actionListener is to have a void method returning to the same page, then that's a bad one. The action methods can perfectly also return void, on the contrary to what some IDEs let you believe via EL validation. Note that the PrimeFaces showcase examples are littered with this kind of actionListeners over all place. This is indeed wrong. Don't use this as an excuse to also do that yourself.

In ajax requests, however, a special exception handler is needed. This is regardless of whether you use listener attribute of <f:ajax> or not. For explanation and an example, head to Exception handling in JSF ajax requests.

public void paintComponent(Graphics g) {
   super.paintComponent(g);
   Graphics2D g2d = (Graphics2D)g;
   // Assume x, y, and diameter are instance variables.
   Ellipse2D.Double circle = new Ellipse2D.Double(x, y, diameter, diameter);
   g2d.fill(circle);
   ...
}

Here are some docs about paintComponent (link).

You should override that method in your JPanel and do something similar to the code snippet above.

In your ActionListener you should specify x, y, diameter and call repaint().

You can use super.dispose() method which is more similar to close operation.

I fixed my problem with placing the:

<h:commandButton class="btn btn-danger" value = "Remove" action="#{deleteEmployeeBean.delete}"></h:commandButton>

In:

<h:form>
     <h:commandButton class="btn btn-danger" value = "Remove" action="#{deleteEmployeeBean.delete}"></h:commandButton>
</h:form>

The first error

java.lang.Exception; must be caught or declared to be thrown byte[] encrypted = encrypt(concatURL);

means that your encrypt method throws an exception that is not being handled or declared by the actionPerformed method where you are calling it. Read all about it at the Java Exceptions Tutorial.

You have a couple of choices that you can pick from to get the code to compile.

• You can remove throws Exception from your encrypt method and actually handle the exception inside encrypt.
• You can remove the try/catch block from encrypt and add throws Exception and the exception handling block to your actionPerformed method.

It's generally better to handle an exception at the lowest level that you can, instead of passing it up to a higher level.

The second error just means that you need to add a return statement to whichever method contains line 109 (also encrypt, in this case). There is a return statement in the method, but if an exception is thrown it might not be reached, so you either need to return in the catch block, or remove the try/catch from encrypt, as I mentioned before.

Two ways:

1. Implement ActionListener in your class, then use jBtnSelection.addActionListener(this); Later, you'll have to define a menthod, public void actionPerformed(ActionEvent e). However, doing this for multiple buttons can be confusing, because the actionPerformed method will have to check the source of each event (e.getSource()) to see which button it came from.

2. Use anonymous inner classes:

jBtnSelection.addActionListener(new ActionListener() { 
  public void actionPerformed(ActionEvent e) { 
    selectionButtonPressed();
  } 
} );

Later, you'll have to define selectionButtonPressed(). This works better when you have multiple buttons, because your calls to individual methods for handling the actions are right next to the definition of the button.

The second method also allows you to call the selection method directly. In this case, you could call selectionButtonPressed() if some other action happens, too - like, when a timer goes off or something (but in this case, your method would be named something different, maybe selectionChanged()).

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target
};

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

You could use the video-out and capture that somehow with a firewire or sumthing.. The class MPTVOutWindow can help you out! Here's a nice sample of that!

While you already have very good answers, I really like the explanation on this website: https://https.cio.gov/faq/#what-information-does-https-protect

in short: using HTTPS hides:

• HTTP method
• query params
• POST body (if present)
• Request headers (cookies included)
• Status code

You can do it programmatically:

grid0.Columns[0].Visible = true;
grid0.DataSource = dt;
grid0.DataBind();
grid0.Columns[0].Visible = false;

In this way you set the column to visible before databinding, so the column is generated. The you set the column to not visible, so it is not displayed.

This code work fine for me, Here i contvert array to string with ~ sign

    <input type="checkbox" value="created" name="today_check"><strong>&nbsp;Created&nbsp;&nbsp;</strong>
    <input type="checkbox" value="modified" name="today_check"><strong>&nbsp;Modified&nbsp;</strong>    
 <a class="get_tody_btn">Submit</a>

<script type="text/javascript">
        $('.get_tody_btn').click(function(){
            var ck_string = "";
            $.each($("input[name='today_check']:checked"), function(){  
                ck_string += "~"+$(this).val();  
            });
            if (ck_string ){
                ck_string = ck_string .substring(1);
            }else{
                alert('Please choose atleast one value.');
            }


        });
    </script>

I try lots of ways and finally try this:

def db_persist(func):
    def persist(*args, **kwargs):
        func(*args, **kwargs)
        try:
            session.commit()
            logger.info("success calling db func: " + func.__name__)
            return True
        except SQLAlchemyError as e:
            logger.error(e.args)
            session.rollback()
            return False

    return persist

and :

@db_persist
def insert_or_update(table_object):
    return session.merge(table_object)

I reproduced this just now by accident:

1. lists the remote branches

   git branch -r
         origin/Feature/f1234
         origin/master
   

2. I want to checkout one locally, so I cut paste:

   git checkout origin/Feature/f1234
   

3. Presto! Detached HEAD state

   You are in 'detached HEAD' state. [...])
   

Solution #1:

Do not include origin/ at the front of my branch spec when checking it out:

git checkout Feature/f1234

Solution #2:

Add -b parameter which creates a local branch from the remote

git checkout -b origin/Feature/f1234 or

git checkout -b Feature/f1234 it will fall back to origin automatically

The following code is my WCF named pipes solution to register a single-instance application. It's nice because it also raises an event when another instance attempts to start, and receives the command line of the other instance.

It's geared toward WPF because it uses the System.Windows.StartupEventHandler class, but this could be easily modified.

This code requires a reference to PresentationFramework, and System.ServiceModel.

Usage:

class Program
{
    static void Main()
    {
        var applicationId = new Guid("b54f7b0d-87f9-4df9-9686-4d8fd76066dc");

        if (SingleInstanceManager.VerifySingleInstance(applicationId))
        {
            SingleInstanceManager.OtherInstanceStarted += OnOtherInstanceStarted;

            // Start the application
        }
    }

    static void OnOtherInstanceStarted(object sender, StartupEventArgs e)
    {
        // Do something in response to another instance starting up.
    }
}

Just use the *args parameter, which allows you to pass as many arguments as you want after your a,b,c. You would have to add some logic to map args->c,d,e,f but its a "way" of overloading.

def myfunc(a,b, *args, **kwargs):
   for ar in args:
      print ar
myfunc(a,b,c,d,e,f)

And it will print values of c,d,e,f

Similarly you could use the kwargs argument and then you could name your parameters.

def myfunc(a,b, *args, **kwargs):
      c = kwargs.get('c', None)
      d = kwargs.get('d', None)
      #etc
myfunc(a,b, c='nick', d='dog', ...)

And then kwargs would have a dictionary of all the parameters that are key valued after a,b

Here is another possible workaround:

if exists (select * from master..sysservers where srvname = 'loopback')
    exec sp_dropserver 'loopback'
go
exec sp_addlinkedserver @server = N'loopback', @srvproduct = N'', @provider = N'SQLOLEDB', @datasrc = @@servername
go

create function testit()
    returns int
as
begin
    declare @res int;
    select @res=count(*) from openquery(loopback, 'exec sp_who');
    return @res
end
go

select dbo.testit()

It's not so scary as xp_cmdshell but also has too many implications for practical use.

On the one hand, throwing exceptions is inherently expensive, because the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

BTW: The correct way to do this is to use TryGetValue

obj item;
if(!dict.TryGetValue(name, out item))
    return null;
return item;

This accesses the dictionary only once instead of twice.
If you really want to just return null if the key doesn't exist, the above code can be simplified further:

obj item;
dict.TryGetValue(name, out item);
return item;

This works, because TryGetValue sets item to null if no key with name exists.

SQL 2008 allows you to forgo specifying column names in your SELECT if you use SELECT INTO rather than INSERT INTO / SELECT:

SELECT *
INTO Foo
FROM Bar
WHERE x=y

The INTO clause does exist in SQL Server 2000-2005, but still requires specifying column names. 2008 appears to add the ability to use SELECT *.

See the MSDN articles on INTO (SQL2005), (SQL2008) for details.

The INTO clause only works if the destination table does not yet exist, however. If you're looking to add records to an existing table, this won't help.

There are different types of shells. The SSH command execution shell is a non-interactive shell, whereas your normal shell is either a login shell or an interactive shell. Description follows, from man bash:

       A  login  shell  is  one whose first character of argument
       zero is a -, or one started with the --login option.

       An interactive shell is  one  started  without  non-option
       arguments  and  without the -c option whose standard input
       and error are both connected to terminals  (as  determined
       by  isatty(3)), or one started with the -i option.  PS1 is
       set and $- includes i if bash is interactive,  allowing  a
       shell script or a startup file to test this state.

       The  following  paragraphs  describe how bash executes its
       startup files.  If any of the files exist  but  cannot  be
       read,  bash reports an error.  Tildes are expanded in file
       names as described below  under  Tilde  Expansion  in  the
       EXPANSION section.

       When  bash is invoked as an interactive login shell, or as
       a non-interactive shell with the --login option, it  first
       reads and executes commands from the file /etc/profile, if
       that file exists.  After reading that file, it  looks  for
       ~/.bash_profile,  ~/.bash_login,  and  ~/.profile, in that
       order, and reads and executes commands from the first  one
       that  exists  and is readable.  The --noprofile option may
       be used when the shell is started to inhibit  this  behav­
       ior.

       When a login shell exits, bash reads and executes commands
       from the file ~/.bash_logout, if it exists.

       When an interactive shell that is not  a  login  shell  is
       started,  bash reads and executes commands from ~/.bashrc,
       if that file exists.  This may be inhibited by  using  the
       --norc  option.   The --rcfile file option will force bash
       to  read  and  execute  commands  from  file  instead   of
       ~/.bashrc.

       When  bash  is  started  non-interactively, to run a shell
       script, for example, it looks for the variable BASH_ENV in
       the  environment,  expands  its value if it appears there,
       and uses the expanded value as the name of a file to  read
       and  execute.   Bash  behaves  as if the following command
       were executed:
              if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
       but the value of the PATH variable is not used  to  search
       for the file name.

work for me

func webView(webView: WKWebView, decidePolicyForNavigationAction navigationAction: WKNavigationAction, decisionHandler: (WKNavigationActionPolicy) -> Void) {
    let headerFields = navigationAction.request.allHTTPHeaderFields
    var headerIsPresent = contains(headerFields?.keys.array as! [String], "Cookie")

    if headerIsPresent {
        decisionHandler(WKNavigationActionPolicy.Allow)

Try like that may you get your solution

String table = "beaconTable";
String whereClause = "_id=?";
String[] whereArgs = new String[] { String.valueOf(row) };
db.delete(table, whereClause, whereArgs);

Open cmd with "Run as administrator" and execute the command pip install mitmproxy. It will install it.

Better to use text box for calling/displaying date and while saving use DateTimePicker. Make visible property true or false as per requirement.

For eg : During form load make Load date in Textbox and make DTPIcker invisible and while adding vice versa

regexp:

"014".replace(/^0+/, '')

window.alert = null;
alert('test'); // fail
delete window.alert; // true
alert('test'); // win

window is an instance of DOMWindow, and by setting something to window.alert, the correct implementation is being "shadowed", i.e. when accessing alert it is first looking for it on the window object. Usually this is not found, and it then goes up the prototype chain to find the native implementation. However, when manually adding the alert property to window it finds it straight away and does not need to go up the prototype chain. Using delete window.alert you can remove the window own property and again expose the prototype implementation of alert. This may help explain:

window.hasOwnProperty('alert'); // false
window.alert = null;
window.hasOwnProperty('alert'); // true
delete window.alert;
window.hasOwnProperty('alert'); // false

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

To use that you need traineddata file. You can download trainddata file from this link.

Once you’ve downloaded the traineddata file you want, you need to make an Android Resource directory named assets in your android project. In the newly created assets folder, you need to create a regular directory named “tessdata” where you can place your traineddata files. Finally you have to init the "TextExtractor" class in your MainActivity.

final TextExtractor textExtractor = new TextExtractor(this, "tessdata", "eng");

First parameter is the context, the second one is the name of directory just created and the last one is the language of traineddata just downloaded.

To extract text you have to call the "extractText" method:

final String text = textExtractor.extractText(imageWithText);

Note that extractText need a BitMap image to work!! You can create a BitMap image from your drawable file with this line:

final BitMap image = BitmapFactory.decodeResource(getResources(), R.drawable.test_image);

I'd suggest you go the other way around by writing unobtrusive JavaScript.

Make the features of your project work for users with JavaScript disabled, and when you're done, implement your JavaScript UI-enhancements.

https://en.wikipedia.org/wiki/Unobtrusive_JavaScript

Copy /usr/local/opt/mysql/support-files/my-default.cnf as /etc/my.cnf or /etc/mysql/my.cnf and then restart mysql.

You can use Unicode strings, they have a method to do just what you want:

>>> s = u"345"
>>> s.isnumeric()
True

Or:

>>> s = "345"
>>> u = unicode(s)
>>> u.isnumeric()
True

http://www.tutorialspoint.com/python/string_isnumeric.htm

http://docs.python.org/2/howto/unicode.html

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

Like many others, I needed to convert a C# project to Java. I did not find a complete solution on the web regarding out and ref modifiers. But, I was able to take the information I found, and expand upon it to create my own classes to fulfill the requirements. I wanted to make a distinction between ref and out parameters for code clarity. With the below classes, it is possible. May this information save others time and effort.

An example is included in the code below.

//*******************************************************************************************

{
    public XOBJ<T> Obj = null;

    public XOUT(T value)

        Obj = new XOBJ<T>(value);
    }

    public XOUT()
    {
      Obj = new XOBJ<T>();
    }

    public XOUT<T> Out()
    {
        return(this);
    }

    public XREF<T> Ref()
    {
        return(Obj.Ref());
    }
};

//*******************************************************************************************
//XREF CLASS
//*******************************************************************************************

public class XREF<T>
{
    public XOBJ<T> Obj = null;

    public XREF(T value)
    {
        Obj = new XOBJ<T>(value);
    }

    public XREF()
    {
      Obj = new XOBJ<T>();
    }

/*
    XOBJ is the base object that houses the value. XREF and XOUT are classes that
    internally use XOBJ. The classes XOBJ, XREF, and XOUT have methods that allow
    the object to be used as XREF or XOUT parameter; This is important, because
    objects of these types are interchangeable.

    See Method:
       XXX.Ref()
       XXX.Out()

    The below example shows how to use XOBJ, XREF, and XOUT;
    //
    // Reference parameter example
    //
    void AddToTotal(int a, XREF<Integer> Total)
    {
       Total.Obj.Value += a;
    }

    //
    // out parameter example
    //
    void Add(int a, int b, XOUT<Integer> ParmOut)
    {
       ParmOut.Obj.Value = a+b;
    }

    //
    // XOBJ example
    //
    int XObjTest()
    {
       XOBJ<Integer> Total = new XOBJ<>(0);
       Add(1, 2, Total.Out());    // Example of using out parameter
       AddToTotal(1,Total.Ref()); // Example of using ref parameter
       return(Total.Value);
    }

public class XOBJ<T> {

    public T Value;

    public  XOBJ() {

    }

    public XOBJ(T value) {
        this.Value = value;

        ref.Obj = this;
        return(ref);
    }

    //
    // Method: Out()
    // Purpose: returns an Out Parameter Object using the XOBJ value
    //
    public XOUT<T> Out()
    {
        XOUT<T> out = new XOUT<T>();

    }

    @Override
    public int hashCode() {
        return Value.hashCode();

}

You can add the following to your pom.xml:

<build>
<defaultGoal>install</defaultGoal>
<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>

Afterwards you have to switch via the console to the directory, where the pom.xml is located. Then you have to execute mvn assembly:single and then your executable JAR file with dependencies will be hopefully build. You can check it when switching to the output (target) directory with cd ./target and starting your jar with a command similiar to java -jar mavenproject1-1.0-SNAPSHOT-jar-with-dependencies.jar.

I tested this with Apache Maven 3.0.3.

Another way to do this is with union:

INSERT INTO Data ( Col1 ) 
select 'hello'
union 
select 'world'

Surely you can. First, return to your tableView number of cells you want to show then call super to achieve certain cell from your storyboard and return it for tableView:

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return self.mode.numberOfCells()
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = super.tableView(tableView, cellForRowAtIndexPath: self.mode.indexPathForIndexPath(indexPath))

    return cell
}

If your cells has different hieght return it too:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return super.tableView(tableView, heightForRowAtIndexPath: self.mode.indexPathForIndexPath(indexPath))
}

Solution: Automation Macros

It sounds like you would benefit from using an automation utility. If you were using a windows PC I would recommend AutoHotkey. I haven't used automation utilities on a Mac, but this Ask Different post has several suggestions, though none appear to be free.

This is not a VBA solution. These macros run outside of Excel and can interact with programs using keyboard strokes, mouse movements and clicks.

Basically you record or write a simple automation macro that waits for the Excel "Save As" dialogue box to become active, hits enter/return to complete the save action and then waits for the "Save As" window to close. You can set it to run in a continuous loop until you manually end the macro.

Here's a simple version of a Windows AutoHotkey script that would accomplish what you are attempting to do on a Mac. It should give you an idea of the logic involved.

Example Automation Macro: AutoHotkey

; ' Infinite loop.  End the macro by closing the program from the Windows taskbar.
Loop {

    ; ' Wait for ANY "Save As" dialogue box in any program.
    ; ' BE CAREFUL!
    ; '  Ignore the "Confirm Save As" dialogue if attempt is made
    ; '  to overwrite an existing file.
    WinWait, Save As,,, Confirm Save As
    IfWinNotActive, Save As,,, Confirm Save As
        WinActivate, Save As,,, Confirm Save As
    WinWaitActive, Save As,,, Confirm Save As

    sleep, 250 ; ' 0.25 second delay
    Send, {ENTER} ; ' Save the Excel file.

    ; ' Wait for the "Save As" dialogue box to close.
    WinWaitClose, Save As,,, Confirm Save As
}

DELETE T2
FROM   table_name T1
JOIN   same_table_name T2 ON (T1.title = T2.title AND T1.ID <> T2.ID)

I believe if your array was actually an object you could return using an empty object.

_.({1,2,3,4,5}).each(function(v){  
  if(v===3) return {}; 
});

Following can be used as a common method to return different arguments on different method calls. Only thing we need to do is we need to pass an array with order in which objects should be retrieved in each call.

@SafeVarargs
public static <Mock> Answer<Mock> getAnswerForSubsequentCalls(final Mock... mockArr) {
    return new Answer<Mock>() {
       private int count=0, size=mockArr.length;
       public Mock answer(InvocationOnMock invocation) throws throwable {
           Mock mock = null;
           for(; count<size && mock==null; count++){
                mock = mockArr[count];
           }

           return mock;    
       } 
    }
}

Ex. getAnswerForSubsequentCalls(mock1, mock3, mock2); will return mock1 object on first call, mock3 object on second call and mock2 object on third call. Should be used like when(something()).doAnswer(getAnswerForSubsequentCalls(mock1, mock3, mock2)); This is almost similar to when(something()).thenReturn(mock1, mock3, mock2);

The modulo operator is % (percent sign). To test for evenness or generally do modulo for a power of 2, you can also use & (the and operator) like isEven = !( a & 1 ).

If you are talking about Python's actual array (available through import array from array), then the principle of least astonishment applies and you can check whether it is empty the same way you'd check if a list is empty.

from array import array
an_array = array('i') # an array of ints

if an_array:
    print("this won't be printed")

an_array.append(3)

if an_array:
    print("this will be printed")

In Kotlin you must use MutableList or ArrayList.

Let's see how the methods of MutableList work:

var listNumbers: MutableList<Int> = mutableListOf(10, 15, 20)
// Result: 10, 15, 20

listNumbers.add(1000)
// Result: 10, 15, 20, 1000

listNumbers.add(1, 250)
// Result: 10, 250, 15, 20, 1000

listNumbers.removeAt(0)
// Result: 250, 15, 20, 1000

listNumbers.remove(20)
// Result: 250, 15, 1000

for (i in listNumbers) { 
    println(i) 
}

Let's see how the methods of ArrayList work:

var arrayNumbers: ArrayList<Int> = arrayListOf(1, 2, 3, 4, 5)
// Result: 1, 2, 3, 4, 5

arrayNumbers.add(20)
// Result: 1, 2, 3, 4, 5, 20

arrayNumbers.remove(1)
// Result: 2, 3, 4, 5, 20

arrayNumbers.clear()
// Result: Empty

for (j in arrayNumbers) { 
    println(j) 
}

Just add your modulus (arrayLength) to the negative result of % and you'll be fine.

use .html() along with selector to get/set HTML:

 $('#detailInfo').html('changed value');

The issue seems to be with autorelease of objects. NSJSONSerialization JSONObjectWithData is obviously creating some autoreleased objects and passing it back to you. If you try to take that on to a different thread, it will not work since it cannot be deallocated on a different thread.

Trick might be to try doing a mutable copy of that dictionary or array and use it.

NSError *e = nil;
id jsonObject = [NSJSONSerialization 
JSONObjectWithData: data 
options: NSJSONReadingMutableContainers 
error: &e] mutableCopy];

Treating a NSDictionary as NSArray will not result in Bad access exception but instead will probably crash when a method call is made.

Also, may be the options do not really matter here but it is better to give NSJSONReadingMutableContainers | NSJSONReadingMutableContainers | NSJSONReadingAllowFragments but even if they are autoreleased objects it may not solve this issue.

About this, java declares that on Windows 10, Edge browser does not support plugins, so it will NOT run java. (see https://www.java.com/it/download/win10.jsp --> only visible with edge in win10) It also reports a notice: java is not officially supported yet in Windows 10. (see https://www.java.com/it/download/faq/win10_faq.xml)

I find the Django template date formatting filter to be quick and easy. It strips out leading zeros. If you don't mind importing the Django module, check it out.

http://docs.djangoproject.com/en/dev/ref/templates/builtins/#date

from django.template.defaultfilters import date as django_date_filter
print django_date_filter(mydate, 'P, D M j, Y')    

From here.

Each tab bar item has a title, selected image, unselected image, and a badge value.

Use the Image Tint (selectedImageTintColor) field to specify the bar item’s tint color when that tab is selected. By default, that color is blue.

You are checking Parent properties for null in your delegate. The same should work with lambda expressions too.

List<AnalysisObject> analysisObjects = analysisObjectRepository
        .FindAll()
        .Where(x => 
            (x.ID == packageId) || 
            (x.Parent != null &&
                (x.Parent.ID == packageId || 
                (x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
        .ToList();

This is exactly what reflection is for. I don't think there's a simpler solution, but reflection isn't that code intensive anyway.

Why to avoid using Session in WebAPI?

Performance, performance, performance!

There's a very good, and often overlooked reason why you shouldn't be using Session in WebAPI at all.

The way ASP.NET works when Session is in use is to serialize all requests received from a single client. Now I'm not talking about object serialization - but running them in the order received and waiting for each to complete before running the next. This is to avoid nasty thread / race conditions if two requests each try to access Session simultaneously.

Concurrent Requests and Session State

Access to ASP.NET session state is exclusive per session, which means that if two different users make concurrent requests, access to each separate session is granted concurrently. However, if two concurrent requests are made for the same session (by using the same SessionID value), the first request gets exclusive access to the session information. The second request executes only after the first request is finished. (The second session can also get access if the exclusive lock on the information is freed because the first request exceeds the lock time-out.) If the EnableSessionState value in the @ Page directive is set to ReadOnly, a request for the read-only session information does not result in an exclusive lock on the session data. However, read-only requests for session data might still have to wait for a lock set by a read-write request for session data to clear.

So what does this mean for Web API? If you have an application running many AJAX requests then only ONE is going to be able to run at a time. If you have a slower request then it will block all others from that client until it is complete. In some applications this could lead to very noticeably sluggish performance.

So you should probably use an MVC controller if you absolutely need something from the users session and avoid the unncesessary performance penalty of enabling it for WebApi.

You can easily test this out for yourself by just putting Thread.Sleep(5000) in a WebAPI method and enable Session. Run 5 requests to it and they will take a total of 25 seconds to complete. Without Session they'll take a total of just over 5 seconds.

(This same reasoning applies to SignalR).

Just for reference which functional interface can be used for method reference in cases method throws and/or returns a value.

void notReturnsNotThrows() {};
void notReturnsThrows() throws Exception {}
String returnsNotThrows() { return ""; }
String returnsThrows() throws Exception { return ""; }

{
    Runnable r1 = this::notReturnsNotThrows; //ok
    Runnable r2 = this::notReturnsThrows; //error
    Runnable r3 = this::returnsNotThrows; //ok
    Runnable r4 = this::returnsThrows; //error

    Callable c1 = this::notReturnsNotThrows; //error
    Callable c2 = this::notReturnsThrows; //error
    Callable c3 = this::returnsNotThrows; //ok
    Callable c4 = this::returnsThrows; //ok

}


interface VoidCallableExtendsCallable extends Callable<Void> {
    @Override
    Void call() throws Exception;
}

interface VoidCallable {
    void call() throws Exception;
}

{
    VoidCallableExtendsCallable vcec1 = this::notReturnsNotThrows; //error
    VoidCallableExtendsCallable vcec2 = this::notReturnsThrows; //error
    VoidCallableExtendsCallable vcec3 = this::returnsNotThrows; //error
    VoidCallableExtendsCallable vcec4 = this::returnsThrows; //error

    VoidCallable vc1 = this::notReturnsNotThrows; //ok
    VoidCallable vc2 = this::notReturnsThrows; //ok
    VoidCallable vc3 = this::returnsNotThrows; //ok
    VoidCallable vc4 = this::returnsThrows; //ok
}

you need RequestOptions

 let headers = new Headers({'Content-Type': 'application/json'});  
 headers.append('Authorization','Bearer ')
 let options = new RequestOptions({headers: headers});
 return this.http.post(APIname,body,options)
  .map(this.extractData)
  .catch(this.handleError);

The code example is exactly this:

from xlutils.copy import copy
from xlrd import *
w = copy(open_workbook('book1.xls'))
w.get_sheet(0).write(0,0,"foo")
w.save('book2.xls')

You'll need to create book1.xls to test, but you get the idea.

The best way to get rid on it is adding or modifying the data-interval attribute like this:

<div data-ride="carousel" class="carousel slide" data-interval="10000" id="myCarousel">

It's specified on ms like it's usually on js, so 1000 = 1s, 3000 = 3s... 10000 = 10s.

By the way you can also specify it at 0 for not sliding automatically. It's useful when showing product images on mobile for example.

<div data-ride="carousel" class="carousel slide" data-interval="0" id="myCarousel">

window load will wait for all resources to be loaded.

document ready waits for the document to be initialized.

unload well, waits till the document is being unloaded.

the order is: document ready, window load, ... ... ... ... window unload.

always use document ready unless you need to wait for your images to load.

shorthand for document ready:

$(function(){
    // yay!
});

Up to and including Java 6 it was possible to do this using the Static Initialization Block as was pointed out in the question Printing message on Console without using main() method. For instance using the following code:

public class Foo {
    static {
         System.out.println("Message");
         System.exit(0);
    } 
}

The System.exit(0) lets the program exit before the JVM is looking for the main method, otherwise the following error will be thrown:

Exception in thread "main" java.lang.NoSuchMethodError: main

In Java 7, however, this does not work anymore, even though it compiles, the following error will appear when you try to execute it:

The program compiled successfully, but main class was not found. Main class should contain method: public static void main (String[] args).

Here an alternative is to write your own launcher, this way you can define entry points as you want.

In the article JVM Launcher you will find the necessary information to get started:

This article explains how can we create a Java Virtual Machine Launcher (like java.exe or javaw.exe). It explores how the Java Virtual Machine launches a Java application. It gives you more ideas on the JDK or JRE you are using. This launcher is very useful in Cygwin (Linux emulator) with Java Native Interface. This article assumes a basic understanding of JNI.

You can call QCoreApplication::exit(0) to exit with code 0

You are comparing a date column to a string literal. In such a case, Oracle attempts to convert your literal to a date, using the default date format. It's a bad practice to rely on such a behavior, as this default may change if the DBA changes some configuration, Oracle breaks something in a future revision, etc.

Instead, you should always explicitly convert your literal to a date and state the format you're using:

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = TO_DATE('23/04/49','MM/DD/YY');

I was facing this issue after pulling from remote master and adding to the appsettings on web.config. I solved it by enabling Windows Authentication:

Click on the project and press f4

Make sure Windows Auth is enabled:

From the command line, you can simply issue:

python -c "import numpy; print(numpy.version.version)"

Or:

python -c "import numpy; print(numpy.__version__)"

Arrays must have zero based integer indexes in JavaScript. So:

var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);

Or maybe you want to use objects (which are associative arrays):

var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);

which is equivalent to:

var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);

It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.

this worked for me on Ubuntu 20.04 with mysql 8, the weird hashing thing is because the native PASSWORD() function was removed in mysql 8 (or earlier?)

UPDATE mysql.user SET 
 plugin = 'mysql_native_password',
 Host = '%',
 authentication_string = CONCAT('*', UPPER(SHA1(UNHEX(SHA1('insert password here'))))) 
WHERE User = 'root';
FLUSH PRIVILEGES;

The more general answer to this question involves shadowed variables and how they are accessed.

In the following example (from Oracle), the variable x in main() is shadowing Test.x:

class Test {
    static int x = 1;
    public static void main(String[] args) {
        InnerClass innerClassInstance = new InnerClass()
        {
            public void printX()
            {
                System.out.print("x=" + x);
                System.out.println(", Test.this.x=" + Test.this.x);
            }
        }
        innerClassInstance.printX();
    }

    public abstract static class InnerClass
    {
        int x = 0;

        public InnerClass() { }

        public abstract void printX();
    }
}

Running this program will print:

x=0, Test.this.x=1

For printing I don't set any width and remove any obstacles which keep your print layout from having a dynamic width. Meaning if you make your browser window smaller and smaller, no content is cut/hidden but the document just gets longer. Like this, you can be sure that the rest will be handled by the printer/pdf-creator.

What about elements with a fixed width such as images or tables?

Images

Options I can think of:

• scale images down in your print CSS to a width which you can assume will fit in any case, use pt not px (but print will need more points/unit anyways, so this should hardly be a problem)
• exclude from being printed

Tables

• remove the fixed width
• use landscape if you really have tables with loads of information
• don't use tables for layout purposes
• exclude from being printed
• extract content, print it as paragraphs

or any other google result for combinations of: CSS, print, media, layout

If you get an error like: cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0, it could be because you don't have a swap file. I suggest you take a look at the tutorial mentioned in this answer: https://stackoverflow.com/a/20275282/828366

Clang's document on Objective-C Automatic Reference Counting (ARC) explains the ownership qualifiers and modifiers clearly:

There are four ownership qualifiers:

• __autoreleasing
• __strong
• __*unsafe_unretained*
• __weak

A type is nontrivially ownership-qualified if it is qualified with __autoreleasing, __strong, or __weak.

Then there are six ownership modifiers for declared property:

• assign implies __*unsafe_unretained* ownership.
• copy implies __strong ownership, as well as the usual behavior of copy semantics on the setter.
• retain implies __strong ownership.
• strong implies __strong ownership.
• *unsafe_unretained* implies __*unsafe_unretained* ownership.
• weak implies __weak ownership.

With the exception of weak, these modifiers are available in non-ARC modes.

Semantics wise, the ownership qualifiers have different meaning in the five managed operations: Reading, Assignment, Initialization, Destruction and Moving, in which most of times we only care about the difference in Assignment operation.

Assignment occurs when evaluating an assignment operator. The semantics vary based on the qualification:

• For __strong objects, the new pointee is first retained; second, the lvalue is loaded with primitive semantics; third, the new pointee is stored into the lvalue with primitive semantics; and finally, the old pointee is released. This is not performed atomically; external synchronization must be used to make this safe in the face of concurrent loads and stores.
• For __weak objects, the lvalue is updated to point to the new pointee, unless the new pointee is an object currently undergoing deallocation, in which case the lvalue is updated to a null pointer. This must execute atomically with respect to other assignments to the object, to reads from the object, and to the final release of the new pointee.
• For __*unsafe_unretained* objects, the new pointee is stored into the lvalue using primitive semantics.
• For __autoreleasing objects, the new pointee is retained, autoreleased, and stored into the lvalue using primitive semantics.

The other difference in Reading, Init, Destruction and Moving, please refer to Section 4.2 Semantics in the document.

Location permission privacy change in Android 10 or Android Q.

We have to define additional ACCESS_BACKGROUND_LOCATION permission if user wants to access their current location in background so user needs to granted permission runtime also in requestPermission()

If we are using lower than Android 10 device then ACCESS_BACKGROUND_LOCATION permission allow automatically with ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permission

This tabular format might be easy to understand what if we don't specify ACCESS_BACKGROUND_LOCATION in manifest file.

AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" /> // here we defined ACCESS_BACKGROUND_LOCATION for Android 10 device

MainActivity.java

Here you can find GPSTracker.java file code

No, you cannot delete the application once you have published it in Google Play. Google will keep all the apk files. But you can unpublish the version, if you dont want that version to be availaible to user.

The problem is described (among other) in this article.

#box is relatively positioned, which makes it part of the "flow" of the page. Your other divs are absolutely positioned, so they are removed from the page's "flow".

Page flow means that the positioning of an element effects other elements in the flow.

In other words, as #box now sees the dom, .a and .b are no longer "inside" #box.

To fix this, you would want to make everything relative, or everything absolute.

One way would be:

.a {
   position:relative;
   margin-top:10px;
   margin-left:10px;
   background-color:red;
   width:210px;
   padding: 5px;
}

You're effectively scanning the list once to find the min value, then scanning it again to find the index, you can do both in one go:

from operator import itemgetter
min(enumerate(a), key=itemgetter(1))[0]

It works..

What is the "Visual C#"? There is no such thing. Just C#, or .NET C# :)

Also, Python's convention for constants CONSTANT_NAME is not very common in C#. We are usually using CamelCase according to MSDN standards, e.g. public const string ExtractedMagicString = "vs2019";

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    private int[] mMeasuredDimension = new int[2];

    @Override
    public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state, int widthSpec, int heightSpec) {

        final int widthMode = View.MeasureSpec.getMode(widthSpec);
        final int heightMode = View.MeasureSpec.getMode(heightSpec);
        final int widthSize = View.MeasureSpec.getSize(widthSpec);
        final int heightSize = View.MeasureSpec.getSize(heightSpec);

        int width = 0;
        int height = 0;
        for (int i = 0; i < getItemCount(); i++) {
            measureScrapChild(recycler, i, View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    mMeasuredDimension);


            if (getOrientation() == HORIZONTAL) {
                width = width + mMeasuredDimension[0];
                if (i == 0) {
                    height = mMeasuredDimension[1];

            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    }

    private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                                   int heightSpec, int[] measuredDimension) {

                        getPaddingTop() + getPaddingBottom(), p.height);

                view.measure(childWidthSpec, childHeightSpec);
                measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
                measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
                recycler.recycleView(view);
            }
        } catch (Exception e) {
            e.printStackTrace();

For Xamarin.Android developers make sure HttpClient implementation and SSL/TLS is set to Default.

It can be found under Andorid Options -> Advanced Android Options.

Please find the default theme in styles.xml

Something like this should work:

I routinely use INSERT IGNORE, and it sounds like exactly the kind of behavior you're looking for as well. As long as you know that rows which would cause index conflicts will not be inserted and you plan your program accordingly, it shouldn't cause any trouble.

Here is sed without buffers (good for real time output).
Example: replacing \n with <br/> break in HTML

echo -e "1\n2\n3" | sed 's/.*$/&<br\/>/'

Make sure that the wheel is, well, supported by your platform. Pip uses the wheel's filename to determine compatibility. The format is:

tensorflow-{version}-{python version}-none-{your platform}.whl

I didn't realize that x86_64 refers to x64, I thought it meant either x86 or x64, so I banged my head against this futilely for some time. Tensorflow is not available for 32 bit systems, unless you want to compile it yourself.

As Daniel A. White said in his comment, the OPTIONS request is most likely created by the client as part of a cross domain JavaScript request. This is done automatically by Cross Origin Resource Sharing (CORS) compliant browsers. The request is a preliminary or pre-flight request, made before the actual AJAX request to determine which request verbs and headers are supported for CORS. The server can elect to support it for none, all or some of the HTTP verbs.

To complete the picture, the AJAX request has an additional "Origin" header, which identified where the original page which is hosting the JavaScript was served from. The server can elect to support request from any origin, or just for a set of known, trusted origins. Allowing any origin is a security risk since is can increase the risk of Cross site Request Forgery (CSRF).

So, you need to enable CORS.

Here is a link that explains how to do this in ASP.Net Web API

http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api#enable-cors

The implementation described there allows you to specify, amongst other things

• CORS support on a per-action, per-controller or global basis
• The supported origins
• When enabling CORS a a controller or global level, the supported HTTP verbs
• Whether the server supports sending credentials with cross-origin requests

In general, this works fine, but you need to make sure you are aware of the security risks, especially if you allow cross origin requests from any domain. Think very carefully before you allow this.

In terms of which browsers support CORS, Wikipedia says the following engines support it:

• Gecko 1.9.1 (FireFox 3.5)
• WebKit (Safari 4, Chrome 3)
• MSHTML/Trident 6 (IE10) with partial support in IE8 and 9
• Presto (Opera 12)

For those who struggle with this error and git bash on Windows, just use PowerShell where -it works perfectly.

As it was said you have a unique index.

However, when I added most of the list yesterday I didn't get this error once even though a lot of the entries I added yesterday have a blank cell in column 2 as well. Whats going on?

That means that all these entries contain value NULL, not empty string ''. Mysql lets you have multiple NULL values in unique fields.

you can use data-tag in html5 and do this using this code:

<script>_x000D_
 $('#mainCat').on('change', function() {_x000D_
  var selected = $(this).val();_x000D_
  $("#expertCat option").each(function(item){_x000D_
   console.log(selected) ;  _x000D_
   var element =  $(this) ; _x000D_
   console.log(element.data("tag")) ; _x000D_
   if (element.data("tag") != selected){_x000D_
    element.hide() ; _x000D_
   }else{_x000D_
    element.show();_x000D_
   }_x000D_
  }) ; _x000D_
  _x000D_
  $("#expertCat").val($("#expertCat option:visible:first").val());_x000D_
  _x000D_
});_x000D_
</script>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>_x000D_
<select id="mainCat">_x000D_
   <option value = '1'>navid</option>_x000D_
   <option value = '2'>javad</option>_x000D_
   <option value = '3'>mamal</option>_x000D_
  </select>_x000D_
  _x000D_
  <select id="expertCat">_x000D_
   <option  value = '1' data-tag='2'>UI</option>_x000D_
   <option  value = '2' data-tag='2'>Java Android</option>_x000D_
   <option  value = '3' data-tag='1'>Web</option>_x000D_
   <option  value = '3' data-tag='1'>Server</option>_x000D_
   <option  value = '3' data-tag='3'>Back End</option>_x000D_
   <option  value = '3' data-tag='3'>.net</option>_x000D_
  </select>

The align-items, or respectively align-content attribute controls this behaviour.

align-items defines the items' positioning perpendicularly to flex-direction.

The default flex-direction is row, therfore vertical placement can be controlled with align-items.

There is also the align-self attribute to control the alignment on a per item basis.

#a {_x000D_
  display:flex;_x000D_
_x000D_
  align-items:flex-start;_x000D_
  align-content:flex-start;_x000D_
  }_x000D_
_x000D_
#a > div {_x000D_
  _x000D_
  background-color:red;_x000D_
  padding:5px;_x000D_
  margin:2px;_x000D_
  }_x000D_
 #a > #c {_x000D_
  align-self:stretch;_x000D_
 }

<div id="a">_x000D_
  _x000D_
  <div id="b">left</div>_x000D_
  <div id="c">middle</div>_x000D_
  <div>right<br>right<br>right<br>right<br>right<br></div>_x000D_
  _x000D_
</div>

css-tricks has an excellent article on the topic. I recommend reading it a couple of times.

I faced the same problem here's the solution:(Explained)

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .antMatchers(HttpMethod.POST,"/form").hasRole("ADMIN")  // Specific api method request based on role.
            .antMatchers("/home","/basic").permitAll()  // permited urls to guest users(without login).
            .anyRequest().authenticated()
            .and()
        .formLogin()       // not specified form page to use default login page of spring security.
            .permitAll()
             .and()
        .logout().deleteCookies("JSESSIONID")  // delete memory of browser after logout.

        .and()
        .rememberMe().key("uniqueAndSecret"); // remember me check box enabled.

    http.csrf().disable();  **// ADD THIS CODE TO DISABLE CSRF IN PROJECT.**
}

Note that the TIMEDIFF() solution only works when the datetimes are less than 35 days apart! TIMEDIFF() returns a TIME datatype, and the max value for TIME is 838:59:59 hours (=34,96 days)

Who ever also stumbles over this post.

I belive is the correct way:

  <div *ngFor="let appointment of (_nextFourAppointments | async).availabilities;"> 
    <div>{{ appointment }}</div>
  </div>

What's you've got there should be fine to work, but there is no actual "Is Mobile/Tablet" media query so you're always going to be stuck.

There are media queries for common breakpoints , but with the ever changing range of devices they're not guaranteed to work moving forwards.

The idea is that your site maintains the same brand across all sizes, so you should want the styles to cascade across the breakpoints and only update the widths and positioning to best suit that viewport.

To further the answer above, using Modernizr with a no-touch test will allow you to target touch devices which are most likely tablets and smart phones, however with the new releases of touch based screens that is not as good an option as it once was.

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

In build.gradle add wrapper { gradleVersion = '6.0' }

Floated elements do not occupy the space inside of the parent element, As the name suggests they float! Thus if a height is explicitly not provided to an element having its child elements floated, then the parent element will appear to shrink & appear to not accepting dimensions of the child element, also if its given overflow:hidden; its children may not appear on screen. There are multiple ways to deal with this problem:

1. Insert another element below the floated element with clear:both; property, or use clear:both; on :after of the floated element.

2. Use display:inline-block; or flex-box instead of float.

You can use the spool command (SQL*Plus documentation, but one of many such commands SQL Developer also supports) to write results straight to disk. Each spool can change the file that's being written to, so you can have several queries writing to different files just by putting spool commands between them:

spool "\path\to\spool1.txt"

select /*csv*/ * from employees;

spool "\path\to\spool2.txt"

select /*csv*/ * from locations;

spool off;

You'd need to run this as a script (F5, or the second button on the command bar above the SQL Worksheet). You might also want to explore some of the formatting options and the set command, though some of those do not translate to SQL Developer.

Since you mentioned CSV in the title I've included a SQL Developer-specific hint that does that formatting for you.

A downside though is that SQL Developer includes the query in the spool file, which you can avoid by having the commands and queries in a script file that you then run as a script.

You can raise a notice in Postgres as follows:

raise notice 'Value: %', deletedContactId;

You can use childFragmentManager inside Fragments.

Single line:

factLabel.numberOfLines = 1;
factLabel.minimumFontSize = 8;
factLabel.adjustsFontSizeToFitWidth = YES;

The above code will adjust your text's font size down to (for example) 8 trying to fit your text within the label. numberOfLines = 1 is mandatory.

Multiple lines:

For numberOfLines > 1 there is a method to figure out the size of final text through NSString's sizeWithFont:... UIKit addition methods, for example:

CGSize lLabelSize = [yourText sizeWithFont:factLabel.font
                                  forWidth:factLabel.frame.size.width
                             lineBreakMode:factLabel.lineBreakMode];

After that you can just resize your label using resulting lLabelSize, for example (assuming that you will change only label's height):

factLabel.frame = CGRectMake(factLabel.frame.origin.x, factLabel.frame.origin.y, factLabel.frame.size.width, lLabelSize.height);

iOS6

Single line:

Starting with iOS6, minimumFontSize has been deprecated. The line

factLabel.minimumFontSize = 8.;

can be changed to:

factLabel.minimumScaleFactor = 8./factLabel.font.pointSize;

iOS7

Multiple lines:

Starting with iOS7, sizeWithFont becomes deprecated. Multiline case is reduced to:

factLabel.numberOfLines = 0;
factLabel.lineBreakMode = NSLineBreakByWordWrapping;
CGSize maximumLabelSize = CGSizeMake(factLabel.frame.size.width, CGFLOAT_MAX);
CGSize expectSize = [factLabel sizeThatFits:maximumLabelSize];
factLabel.frame = CGRectMake(factLabel.frame.origin.x, factLabel.frame.origin.y, expectSize.width, expectSize.height);

iOS 13 (Swift 5):

label.adjustsFontSizeToFitWidth = true
label.minimumScaleFactor = 0.5

i) what is the difference between these two objects

The simple answer is that [object] indicates a host object that has no internal class. A host object is an object that is not part of the ECMAScript implementation you're working with, but is provided by the host as an extension. The DOM is a common example of host objects, although in most newer implementations DOM objects inherit from the native Object and have internal class names (such as HTMLElement, Window, etc). IE's proprietary ActiveXObject is another example of a host object.

[object] is most commonly seen when alerting DOM objects in Internet Explorer 7 and lower, since they are host objects that have no internal class name.

ii) what type of Object is this

You can get the "type" (internal class) of object using Object.prototype.toString. The specification requires that it always returns a string in the format [object [[Class]]], where [[Class]] is the internal class name such as Object, Array, Date, RegExp, etc. You can apply this method to any object (including host objects), using

Object.prototype.toString.apply(obj);

Many isArray implementations use this technique to discover whether an object is actually an array (although it's not as robust in IE as it is in other browsers).

iii) what all properties does this object contains and values of each property

In ECMAScript 3, you can iterate over enumerable properties using a for...in loop. Note that most built-in properties are non-enumerable. The same is true of some host objects. In ECMAScript 5, you can get an array containing the names of all non-inherited properties using Object.getOwnPropertyNames(obj). This array will contain non-enumerable and enumerable property names.

Try this:

Right(RC[-1],Len(RC[-1])-InStrRev(RC[-1]," "))

@poulter7: I cannot comment on the other answers, so I post it as new answer: be careful with

np.log(df.price).diff() 

as this will fail for indices which can become negative as well as risk factors e.g. negative interest rates. In these cases

np.log(df.price/df.price.shift(1)).dropna()

is preferred and based on my experience generally the safer approach. It also evaluates the logarithm only once.

Whether you use +1 or -1 depends on the ordering of your time series. Use -1 for descending and +1 for ascending dates - in both cases the shift provides the preceding date's value.

(Jun-Dec 2016) Most answers here are now out-of-date as: 1) GData APIs are the previous generation of Google APIs, and that's why it was hard for @Josh Brown to find that old GData Docs API documentation. While not all GData APIs have been deprecated, all newer Google APIs do not use the Google Data protocol; and 2) Google released a new Google Sheets API (not GData). In order to use the new API, you need to get the Google APIs Client Library for Python (it's as easy as pip install -U google-api-python-client [or pip3 for Python 3]) and use the latest Sheets API v4+, which is much more powerful & flexible than older API releases.

Here's one code sample from the official docs to help get you kickstarted. However, here are slightly longer, more "real-world" examples of using the API you can learn from (videos plus blog posts):

• Migrating SQL data to a Sheet plus code deep dive post
• Formatting text using the Sheets API plus code deep dive post
• Generating slides from spreadsheet data plus code deep dive post
• Those and others in the Sheets API video library

The latest Sheets API provides features not available in older releases, namely giving developers programmatic access to a Sheet as if you were using the user interface (create frozen rows, perform cell formatting, resizing rows/columns, adding pivot tables, creating charts, etc.), but NOT as if it was some database that you could perform searches on and get selected rows from. You'd basically have to build a querying layer on top of the API that does this. One alternative is to use the Google Charts Visualization API query language, which does support SQL-like querying. You can also query from within the Sheet itself. Be aware that this functionality existed before the v4 API, and that the security model was updated in Aug 2016. To learn more, check my G+ reshare to a full write-up from a Google Developer Expert.

Also note that the Sheets API is primarily for programmatically accessing spreadsheet operations & functionality as described above, but to perform file-level access such as imports/exports, copy, move, rename, etc., use the Google Drive API instead. Examples of using the Drive API:

• Listing your files in Google Drive and code deep dive post
• Google Drive: Uploading & Downloading Files plus "Poor man's plain text to PDF converter" code deep dive post (*)
• Exporting a Google Sheet as CSV blog post only

(*) - TL;DR: upload plain text file to Drive, import/convert to Google Docs format, then export that Doc as PDF. Post above uses Drive API v2; this follow-up post describes migrating it to Drive API v3, and here's a developer video combining both "poor man's converter" posts.

To learn more about how to use Google APIs with Python in general, check out my blog as well as a variety of Google developer videos (series 1 and series 2) I'm producing.

ps. As far as Google Docs goes, there isn't a REST API available at this time, so the only way to programmatically access a Doc is by using Google Apps Script (which like Node.js is JavaScript outside of the browser, but instead of running on a Node server, these apps run in Google's cloud; also check out my intro video.) With Apps Script, you can build a Docs app or an add-on for Docs (and other things like Sheets & Forms).

UPDATE Jul 2018: The above "ps." is no longer true. The G Suite developer team pre-announced a new Google Docs REST API at Google Cloud NEXT '18. Developers interested in getting into the early access program for the new API should register at https://developers.google.com/docs.

UPDATE Feb 2019: The Docs API launched to preview last July is now available generally to all... read the launch post for more details.

UPDATE Nov 2019: In an effort to bring G Suite and GCP APIs more inline with each other, earlier this year, all G Suite code samples were partially integrated with GCP's newer (lower-level not product) Python client libraries. The way auth is done is similar but (currently) requires a tiny bit more code to manage token storage, meaning rather than our libraries manage storage.json, you'll store them using pickle (token.pickle or whatever name you prefer) instead, or choose your own form of persistent storage. For you readers here, take a look at the updated Python quickstart example.

You can use modulo to determine if x is an integer numerically. The isinstance(x, int) method only determines if x is an integer by type:

def isInt(x):
    if x%1 == 0:
        print "X is an integer"
    else:
        print "X is not an integer"

and then restart your terminal.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

Ps: Apparently I can’t comment, so I’m obligated to post it as an answer ...

Here's a complete example of how it can be done. However you need flashback query privileges on the child table.

Here's the setup.

create table parent_tab
  (parent_id number primary key,
  val varchar2(20));

create table child_tab
    (child_id number primary key,
    parent_id number,
    child_val number,
     constraint child_par_fk foreign key (parent_id) references parent_tab);

insert into parent_tab values (1,'Red');
insert into parent_tab values (2,'Green');
insert into parent_tab values (3,'Blue');
insert into parent_tab values (4,'Black');
insert into parent_tab values (5,'White');

insert into child_tab values (10,1,100);
insert into child_tab values (20,3,100);
insert into child_tab values (30,3,100);
insert into child_tab values (40,4,100);
insert into child_tab values (50,5,200);

commit;

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

Now delete a subset of the children (ones with parents 1,3 and 4 - but not 5).

delete from child_tab where child_val = 100;

Then get the parent_ids from the current COMMITTED state of the child_tab (ie as they were prior to your deletes) and remove those that your session has NOT deleted. That gives you the subset that have been deleted. You can then delete those out of the parent_tab

delete from parent_tab
where parent_id in
  (select parent_id from child_tab as of scn dbms_flashback.get_system_change_number
  minus
  select parent_id from child_tab);

'Green' is still there (as it didn't have an entry in the child table anyway) and 'Red' is still there (as it still has an entry in the child table)

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

select * from parent_tab;

It is an exotic/unusual operation, so if i was doing it I'd probably be a bit cautious and lock both child and parent tables in exclusive mode at the start of the transaction. Also, if the child table was big it wouldn't be particularly performant so I'd opt for a PL/SQL solution like Rajesh's.

A very simple example:

SET a=Hello
SET b=World
SET c=%a% %b%!
echo %c%

The result should be:

Hello World!

great answer by @Rarw. Try using a bundle to pass information from one fragment to another

Although this is valid in HTML, you can't use an ID starting with an integer in CSS selectors.

As pointed out, you can use getElementById instead, but you can also still achieve the same with a querySelector:

document.querySelector("[id='22']")

With jQuery (and without FormData API) you can use something like this:

function readFile(file){
   var loader = new FileReader();
   var def = $.Deferred(), promise = def.promise();

   //--- provide classic deferred interface
   loader.onload = function (e) { def.resolve(e.target.result); };
   loader.onprogress = loader.onloadstart = function (e) { def.notify(e); };
   loader.onerror = loader.onabort = function (e) { def.reject(e); };
   promise.abort = function () { return loader.abort.apply(loader, arguments); };

   loader.readAsBinaryString(file);

   return promise;
}

function upload(url, data){
    var def = $.Deferred(), promise = def.promise();
    var mul = buildMultipart(data);
    var req = $.ajax({
        url: url,
        data: mul.data,
        processData: false,
        type: "post",
        async: true,
        contentType: "multipart/form-data; boundary="+mul.bound,
        xhr: function() {
            var xhr = jQuery.ajaxSettings.xhr();
            if (xhr.upload) {

                xhr.upload.addEventListener('progress', function(event) {
                    var percent = 0;
                    var position = event.loaded || event.position; /*event.position is deprecated*/
                    var total = event.total;
                    if (event.lengthComputable) {
                        percent = Math.ceil(position / total * 100);
                        def.notify(percent);
                    }                    
                }, false);
            }
            return xhr;
        }
    });
    req.done(function(){ def.resolve.apply(def, arguments); })
       .fail(function(){ def.reject.apply(def, arguments); });

    promise.abort = function(){ return req.abort.apply(req, arguments); }

    return promise;
}

var buildMultipart = function(data){
    var key, crunks = [], bound = false;
    while (!bound) {
        bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf());
        for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; }
    }

    for (var key = 0, l = data.length; key < l; key++){
        if (typeof(data[key].value) !== "string") {
            crunks.push("--"+bound+"\r\n"+
                "Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+
                "Content-Type: application/octet-stream\r\n"+
                "Content-Transfer-Encoding: binary\r\n\r\n"+
                data[key].value[0]);
        }else{
            crunks.push("--"+bound+"\r\n"+
                "Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+
                data[key].value);
        }
    }

    return {
        bound: bound,
        data: crunks.join("\r\n")+"\r\n--"+bound+"--"
    };
};

//----------
//---------- On submit form:
var form = $("form");
var $file = form.find("#file");
readFile($file[0].files[0]).done(function(fileData){
   var formData = form.find(":input:not('#file')").serializeArray();
   formData.file = [fileData, $file[0].files[0].name];
   upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); });
});

With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})

Option 1:

You can set CMake variables at command line like this:

cmake -D CMAKE_C_COMPILER="/path/to/your/c/compiler/executable" -D CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable" /path/to/directory/containing/CMakeLists.txt

See this to learn how to create a CMake cache entry.

Option 2:

In your shell script build_ios.sh you can set environment variables CC and CXX to point to your C and C++ compiler executable respectively, example:

export CC=/path/to/your/c/compiler/executable
export CXX=/path/to/your/cpp/compiler/executable
cmake /path/to/directory/containing/CMakeLists.txt

Option 3:

Edit the CMakeLists.txt file of "Assimp": Add these lines at the top (must be added before you use project() or enable_language() command)

set(CMAKE_C_COMPILER "/path/to/your/c/compiler/executable")
set(CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable")

See this to learn how to use set command in CMake. Also this is a useful resource for understanding use of some of the common CMake variables.

Here is the relevant entry from the official FAQ: https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-do-i-use-a-different-compiler

In my experience in most cases JSON in a file is enough (mostly you need to store an array or an object or just a single number or string). I rarely need SQLite (which needs more time for setting it up and using it, most of the times it's overkill).

Try

cordova platform version

It will give you the following output

Installed platforms: android 3.5.1, ios 3.5.0
Available platforms: amazon-fireos, blackberry10, browser, firefoxos

Also to know the version of cordodva cli try

cordova -v 

With Swift 3, Dictionary has a keys property. keys has the following declaration:

var keys: LazyMapCollection<Dictionary<Key, Value>, Key> { get }

A collection containing just the keys of the dictionary.

Note that LazyMapCollection that can easily be mapped to an Array with Array's init(_:) initializer.

From NSDictionary to [String]

The following iOS AppDelegate class snippet shows how to get an array of strings ([String]) using keys property from a NSDictionary:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    let string = Bundle.main.path(forResource: "Components", ofType: "plist")!
    if let dict = NSDictionary(contentsOfFile: string) as? [String : Int] {
        let lazyMapCollection = dict.keys
        
        let componentArray = Array(lazyMapCollection)
        print(componentArray)
        // prints: ["Car", "Boat"]
    }
    
    return true
}

From [String: Int] to [String]

In a more general way, the following Playground code shows how to get an array of strings ([String]) using keys property from a dictionary with string keys and integer values ([String: Int]):

let dictionary = ["Gabrielle": 49, "Bree": 32, "Susan": 12, "Lynette": 7]
let lazyMapCollection = dictionary.keys

let stringArray = Array(lazyMapCollection)
print(stringArray)
// prints: ["Bree", "Susan", "Lynette", "Gabrielle"]

From [Int: String] to [String]

The following Playground code shows how to get an array of strings ([String]) using keys property from a dictionary with integer keys and string values ([Int: String]):

let dictionary = [49: "Gabrielle", 32: "Bree", 12: "Susan", 7: "Lynette"]
let lazyMapCollection = dictionary.keys
    
let stringArray = Array(lazyMapCollection.map { String($0) })
// let stringArray = Array(lazyMapCollection).map { String($0) } // also works
print(stringArray)
// prints: ["32", "12", "7", "49"]

The most likely reason for the error is that the certificate authority that issued your SSL certificate is trusted on your desktop, but not on your mobile.

If you purchased the certificate from a common certification authority, it shouldn't be an issue - but if it is a less common one it is possible that your phone doesn't have it. You may need to accept it as a trusted publisher (although this is not ideal if you are pushing the site to the public as they won't be willing to do this.)

You might find looking at a list of Trusted CAs for Android helps to see if yours is there or not.

Most basic and general explanation: cryptography is all about number theory, and all integer numbers (except 0 and 1) are made up of primes, so you deal with primes a lot in number theory.

More specifically, some important cryptographic algorithms such as RSA critically depend on the fact that prime factorization of large numbers takes a long time. Basically you have a "public key" consisting of a product of two large primes used to encrypt a message, and a "secret key" consisting of those two primes used to decrypt the message. You can make the public key public, and everyone can use it to encrypt messages to you, but only you know the prime factors and can decrypt the messages. Everyone else would have to factor the number, which takes too long to be practical, given the current state of the art of number theory.

Simply do this

$get = explode('&', $_POST['seri']); // explode with and

foreach ($get as $key => $value) {
    $need[substr($value, 0 , strpos($value, '='))] =  substr(
        $value, 
        strpos( $value, '=' ) + 1 
    );
}

// access your query param name=ddd&email=aaaaa&username=wwwww&password=wwww&password=eeee
var_dump($need['name']);

This blog shows how to update the registry so the Android SDK can find your Java SDK on a 64-bit machine.

http://codearetoy.wordpress.com/2010/12/23/jdk-not-found-on-installing-android-sdk/

The other answers are correct but you can omit the [attr.data-index] altogether and just use

<ul>
    <li *ngFor="let item of items; let i = index">{{i + 1}}</li>
</ul

Adding another entry for the debate about whether batch normalization should be called before or after the non-linear activation:

In addition to the original paper using batch normalization before the activation, Bengio's book Deep Learning, section 8.7.1 gives some reasoning for why applying batch normalization after the activation (or directly before the input to the next layer) may cause some issues:

It is natural to wonder whether we should apply batch normalization to the input X, or to the transformed value XW+b. Io?e and Szegedy (2015) recommend the latter. More speci?cally, XW+b should be replaced by a normalized version of XW. The bias term should be omitted because it becomes redundant with the ß parameter applied by the batch normalization reparameterization. The input to a layer is usually the output of a nonlinear activation function such as the recti?ed linear function in a previous layer. The statistics of the input are thus more non-Gaussian and less amenable to standardization by linear operations.

In other words, if we use a relu activation, all negative values are mapped to zero. This will likely result in a mean value that is already very close to zero, but the distribution of the remaining data will be heavily skewed to the right. Trying to normalize that data to a nice bell-shaped curve probably won't give the best results. For activations outside of the relu family this may not be as big of an issue.

Keep in mind that there are reports of models getting better results when using batch normalization after the activation, while others get best results when the batch normalization is placed before the activation. It is probably best to test your model using both configurations, and if batch normalization after activation gives a significant decrease in validation loss, use that configuration instead.

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

Use FromResult Method

public async Task<string> GetString()
{
   System.Threading.Thread.Sleep(5000);
   return await Task.FromResult("Hello");
}

Double escaping is required when presented as a string.

Whenever I'm making a new regular expression I do a bunch of tests with online tools, for example: http://www.regexplanet.com/advanced/java/index.html

That website allows you to enter the regular expression, which it'll escape into a string for you, and you can then test it against different inputs.

I have encountered this problem as well. Here is my solution:

In order to resolve this issue you need to do the following in the controller class:-

1. Change the import package from "import org.springframework.web.portlet.ModelAndView;" to "import org.springframework.web.servlet.ModelAndView;"...
2. Recompile and run the code... the problem should get resolved.

I have a similar problem (at least I think it is similar). In one of the replies here the solution is as follows:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

That WHERE clause I would like to be:

WHERE B.tag = A.<col_name>

or, in my specific case:

WHERE B.val BETWEEN A.val1 AND A.val2

More detailed:

Table A carries status information of a fleet of equipment. Each status record carries with it a start and stop time of that status. Table B carries regularly recorded, timestamped data about the equipment, which I want to extract for the duration of the period indicated in table A.

This also happens when using empty on a function return:

!empty(trim($someText)) and doSomething()

because empty is not a function but a language construct (not sure), and it only takes variables:

Right:

empty($someVar)

Wrong:

empty(someFunc())

Since PHP 5.5, it supports more than variables. But if you need it before 5.5, use trim($name) == false. From empty documentation.

TL;DR;

Use let...of instead of let...in !!

If you're new to Angular (>2.x) and possibly migrating from Angular1.x, most likely you're confusing in with of. As andreas has mentioned in the comments below for ... of iterates over values of an object while for ... in iterates over properties in an object. This is a new feature introduced in ES2015.

Simply replace:

<!-- Iterate over properties (incorrect in our case here) -->
<div *ngFor="let talk in talks">

with

<!-- Iterate over values (correct way to use here) -->
<div *ngFor="let talk of talks">

So, you must replace in with of inside ngFor directive to get the values.

My framework was working before and suddenly stopped working, and none of these answers were working for me. I removed the framework in Build Phases > Link Binary With Libraries, and re-added it. Started working again.

The 'new' way to install tensorflow GPU if you have Nvidia, is with Anaconda. Works on Windows too. With 1 line.

conda create --name tf_gpu tensorflow-gpu 

This is a shortcut for 3 commands, which you can execute separately if you want or if you already have a conda environment and do not need to create one.

1. Create an anaconda environment conda create --name tf_gpu

2. Activate the environment activate tf_gpu

3. Install tensorflow-GPU conda install tensorflow-gpu

You can use the conda environment.

long start = System.currentTimeMillis();
long end = start + 60*1000; // 60 seconds * 1000 ms/sec

A bit late to the party but might be valuable to someone with this error..

I just straight copied a bunch of files into an Xcode project, if you forget to add them to your projects Build Phases you will get the error "Undefined symbols for architecture i386". So add your implementation files to Compile Sources, and Xib files to Copy Bundle Resources.

The error was telling me that there was no link to my classes simply because they weren't included in the Compile Sources, quite obvious really but may save someone a headache.

Assuming there are two dictionaries with exact same keys, below is the most succinct way of doing it (python3 should be used for both the solution).

d1 = {'a': 1, 'b': 2, 'c':3}
d2 = {'a': 5, 'b': 6, 'c':7} 

# get keys from one of the dictionary
ks = [k for k in d1.keys()]

print(ks)
['a', 'b', 'c']

# call values from each dictionary on available keys
d_merged = {k: (d1[k], d2[k]) for k in ks}

print(d_merged)
{'a': (1, 5), 'b': (2, 6), 'c': (3, 7)}

# to merge values as list
d_merged = {k: [d1[k], d2[k]] for k in ks}
print(d_merged)
{'a': [1, 5], 'b': [2, 6], 'c': [3, 7]}

If there are two dictionaries with some common keys, but a few different keys, a list of all the keys should be prepared.

d1 = {'a': 1, 'b': 2, 'c':3, 'd': 9}
d2 = {'a': 5, 'b': 6, 'c':7, 'e': 4} 

# get keys from one of the dictionary
d1_ks = [k for k in d1.keys()]
d2_ks = [k for k in d2.keys()]

all_ks = set(d1_ks + d2_ks)

print(all_ks)
['a', 'b', 'c', 'd', 'e']

# call values from each dictionary on available keys
d_merged = {k: [d1.get(k), d2.get(k)] for k in all_ks}

print(d_merged)
{'d': [9, None], 'a': [1, 5], 'b': [2, 6], 'c': [3, 7], 'e': [None, 4]}

basically this ...

declare @currentdate datetime = getdate()
select left(datename(month,DATEADD(MONTH, -1, GETDATE())),3)
union all
select left(datename(month,(DATEADD(MONTH, -2, GETDATE()))),3)
union all
select left(datename(month,(DATEADD(MONTH, -3, GETDATE()))),3)

Bootstrap Modal Events:

1. hide.bs.modal => Occurs when the modal is about to be hidden.
2. hidden.bs.modal => Occurs when the modal is fully hidden (after CSS transitions have completed).

<script type="text/javascript">
    $("#salesitems_modal").on('hide.bs.modal', function () {
        //actions you want to perform after modal is closed.
    });
</script>

I hope this will Help.

 write main.c like this - 
 caution : while linking both main.0 and ClasseAusiliaria.o should be 
 available to linker.

 #include <stdlib.h>
 #include <stdio.h>
 extern int addizione(int a, int b)

 int main(void)
 {
     int risultato;
     risultato = addizione(5,6);
     printf("%d\n",risultato);
 }

So first of all, pandas updates using the index. When an update command does not update anything, check both left-hand side and right-hand side. If you don't update the indices to follow your identification logic, you can do something along the lines of

>>> df.loc[df.filename == 'test2.dat', 'n'] = df2[df2.filename == 'test2.dat'].loc[0]['n']
>>> df
Out[331]: 
    filename   m     n
0  test0.dat  12  None
1  test2.dat  13    16

If you want to do this for the whole table, I suggest a method I believe is superior to the previously mentioned ones: since your identifier is filename, set filename as your index, and then use update() as you wanted to. Both merge and the apply() approach contain unnecessary overhead:

>>> df.set_index('filename', inplace=True)
>>> df2.set_index('filename', inplace=True)
>>> df.update(df2)
>>> df
Out[292]: 
            m     n
filename           
test0.dat  12  None
test2.dat  13    16

Better yet, use JodaTime. Much easier to parse strings and into strings. Is thread safe as well. Worth the time it will take you to implement it.

Just to add my two cents in the debate I have made a pure angular module (no jQuery), and it will also work with hash urls containing data. (e.g. #/this/is/path?this=is&some=data)

You just add the module as a dependency and auto-active to one of the ancestors of the menu. Like this:

<ul auto-active>
    <li><a href="#/">main</a></li>
    <li><a href="#/first">first</a></li>
    <li><a href="#/second">second</a></li>
    <li><a href="#/third">third</a></li>
</ul>

And the module look like this:

(function () {
    angular.module('autoActive', [])
        .directive('autoActive', ['$location', function ($location) {
        return {
            restrict: 'A',
            scope: false,
            link: function (scope, element) {
                function setActive() {
                    var path = $location.path();
                    if (path) {
                        angular.forEach(element.find('li'), function (li) {
                            var anchor = li.querySelector('a');
                            if (anchor.href.match('#' + path + '(?=\\?|$)')) {
                                angular.element(li).addClass('active');
                            } else {
                                angular.element(li).removeClass('active');
                            }
                        });
                    }
                }

                setActive();

                scope.$on('$locationChangeSuccess', setActive);
            }
        }
    }]);
}());

(You can of course just use the directive part)

It's also worth noticing that this doesn't work for empty hashes (e.g. example.com/# or just example.com) it needs to have at least example.com/#/ or just example.com#/. But this happens automatically with ngResource and the like.

And here is the fiddle: http://jsfiddle.net/gy2an/8/

if you look to support old version pre lolipop

use the same xml code with some changes

instead of normal ImageView --> AppCompatImageView

instead of android:src --> app:srcCompat

here is example

<android.support.v7.widget.AppCompatImageView
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/button"
        app:srcCompat="@drawable/ic_more_vert_24dp"
        android:tint="@color/primary" />

dont forget update your gradle as @ Sayooj Valsan mention

// Gradle Plugin 2.0+  
 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
   }  
 }  

 compile 'com.android.support:design:23.4.0'

Notice To any one use vector dont ever ever never give your vector reference to color like this one android:fillColor="@color/primary" give its hex value .

Magic commands such as

%matplotlib qt  

work in the iPython console and Notebook, but do not work within a script.

In that case, after importing:

from IPython import get_ipython

use:

get_ipython().run_line_magic('matplotlib', 'inline')

for inline plotting of the following code, and

get_ipython().run_line_magic('matplotlib', 'qt')

for plotting in an external window.

Edit: solution above does not always work, depending on your OS/Spyder version Anaconda issue on GitHub. Setting the Graphics Backend to Automatic (as indicated in another answer: Tools >> Preferences >> IPython console >> Graphics --> Automatic) solves the problem for me.

Then, after a Console restart, one can switch between Inline and External plot windows using the get_ipython() command, without having to restart the console.

Here is my solution :-

function frequent(number){_x000D_
    var count = 0;_x000D_
    var sortedNumber = number.sort();_x000D_
    var start = number[0], item;_x000D_
    for(var i = 0 ;  i < sortedNumber.length; i++){_x000D_
      if(start === sortedNumber[i] || sortedNumber[i] === sortedNumber[i+1]){_x000D_
         item = sortedNumber[i]_x000D_
      }_x000D_
    }_x000D_
    return item_x000D_
  _x000D_
}_x000D_
_x000D_
   console.log( frequent(['pear', 'apple', 'orange', 'apple']))

The nohup command is a signal masking utility and catches the hangup signal. Where as ampersand doesn’t catch the hang up signals. The shell will terminate the sub command with the hang up signal when running a command using & and exiting the shell. This can be prevented by using nohup, as it catches the signal. Nohup command accept hang up signal which can be sent to a process by the kernel and block them. Nohup command is helpful in when a user wants to start long running application log out or close the window in which the process was initiated. Either of these actions normally prompts the kernel to hang up on the application, but a nohup wrapper will allow the process to continue. Using the ampersand will run the command in a child process and this child of the current bash session. When you exit the session, all of the child processes of that process will be killed. The ampersand relates to job control for the active shell. This is useful for running a process in a session in the background.

There are several places on Windows where SVN will place cached credentials depending on system configuration. Read SVNBook | Client Credentials.

• The main credential store is located in %APPDATA%\Subversion\auth and you can run svn auth command to view and manage its contents.

• You can also run cmdkey to view the credentials stored in Windows Credential Manager.

• If your SVN server is integrated with Active Directory and supports Integrated Windows Authentication such as VisualSVN Server, your Windows logon credentials are used for authentication, but they are not cached. You can run whoami to find out your user account name.

If that empty Date really bugs you, you can also to create a simpler Time structure:

// more work is required to make this even close to production ready
class Time
{
    // TODO: don't forget to add validation
    public int Hours   { get; set; }
    public int Minutes { get; set; }
    public int Seconds { get; set; }

    public override string ToString()
    {  
        return String.Format(
            "{0:00}:{1:00}:{2:00}",
            this.Hours, this.Minutes, this.Seconds);
    }
}

Or, why to bother: if you don't need to do any calculation with that information, just store it as String.

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

You might looking for the placeholder attribute which will display a grey text in the input field while empty.

From Mozilla Developer Network:

A hint to the user of what can be entered in the control . The placeholder text must not contain carriage returns or line-feeds. This attribute applies when the value of the type attribute is text, search, tel, url or email; otherwise it is ignored.

However as it's a fairly 'new' tag (from the HTML5 specification afaik) you might want to to browser testing to make sure your target audience is fine with this solution.
(If not tell tell them to upgrade browser 'cause this tag works like a charm ;o) )

And finally a mini-fiddle to see it directly in action: http://jsfiddle.net/LnU9t/

Edit: Here is a plain jQuery solution which will also clear the input field if an escape keystroke is detected: http://jsfiddle.net/3GLwE/

You can use laravel MessageBag to add our own messages to existing messages.

To use MessageBag you need to use:

use Illuminate\Support\MessageBag;

In the controller:

MessageBag $message_bag

$message_bag->add('message', trans('auth.confirmation-success'));

return redirect('login')->withSuccess($message_bag);

Hope it will help some one.

Something like this should do the trick (However, read after the snippet for more info)

CREATE PROCEDURE GetFilteredData()
BEGIN
  DECLARE bDone INT;

  DECLARE var1 CHAR(16);    -- or approriate type
  DECLARE Var2 INT;
  DECLARE Var3 VARCHAR(50);

  DECLARE curs CURSOR FOR  SELECT something FROM somewhere WHERE some stuff;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;

  DROP TEMPORARY TABLE IF EXISTS tblResults;
  CREATE TEMPORARY TABLE IF NOT EXISTS tblResults  (
    --Fld1 type,
    --Fld2 type,
    --...
  );

  OPEN curs;

  SET bDone = 0;
  REPEAT
    FETCH curs INTO var1,, b;

    IF whatever_filtering_desired
       -- here for whatever_transformation_may_be_desired
       INSERT INTO tblResults VALUES (var1, var2, var3 ...);
    END IF;
  UNTIL bDone END REPEAT;

  CLOSE curs;
  SELECT * FROM tblResults;
END

A few things to consider...

Concerning the snippet above:

• may want to pass part of the query to the Stored Procedure, maybe particularly the search criteria, to make it more generic.
• If this method is to be called by multiple sessions etc. may want to pass a Session ID of sort to create a unique temporary table name (actually unnecessary concern since different sessions do not share the same temporary file namespace; see comment by Gruber, below)
• A few parts such as the variable declarations, the SELECT query etc. need to be properly specified

More generally: trying to avoid needing a cursor.

I purposely named the cursor variable curs[e], because cursors are a mixed blessing. They can help us implement complicated business rules that may be difficult to express in the declarative form of SQL, but it then brings us to use the procedural (imperative) form of SQL, which is a general feature of SQL which is neither very friendly/expressive, programming-wise, and often less efficient performance-wise.

Maybe you can look into expressing the transformation and filtering desired in the context of a "plain" (declarative) SQL query.

We can do this simply,

• create a New Issue on GitHub
• drag and drop images on the body div of Issue

after a few seconds, a link will be generated. Now, copy the link or image URL and use it any supported platform.

Here is a simple example using #ref to scroll to the bottom of a div.

/*_x000D_
Defined somewhere:_x000D_
  var vueContent = new Vue({_x000D_
      el: '#vue-content',_x000D_
      ..._x000D_
 */_x000D_
_x000D_
var messageDisplay = vueContent.$refs.messageDisplay;_x000D_
messageDisplay.scrollTop = messageDisplay.scrollHeight;

<div id='vue-content'>_x000D_
  <div ref='messageDisplay' id='messages'>_x000D_
    <div v-for="message in messages">_x000D_
      {{ message }}_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Notice that by putting ref='messageDisplay' in the HTML, you have access to the element through vueContent.$refs.messageDisplay

I prefer just setting it from the declare statement

DECLARE @ModelID uniqueidentifer = (SELECT modelid 
                                    FROM models
                                    WHERE areaid = 'South Coast')

Why not try find /usr/include/X11 -name Xlib.h

If there is a hit, you have Xlib.h

If not install it using sudo apt-get install libx11-dev

and you are good to go :)

#include<stdio.h>

int main() {
int num; //given integer
int reminder;
int rev=0; //To reverse the given integer
int count=1;

printf("Enter the integer:");
scanf("%i",&num);

/*First while loop will reverse the number*/
while(num!=0)
{
    reminder=num%10;
    rev=rev*10+reminder;
    num/=10;
}
/*Second while loop will give the number from left to right*/
while(rev!=0)
{
    reminder=rev%10;
    printf("The %d digit is %d\n",count, reminder);
    rev/=10;
    count++; //to give the number from left to right 
}
return (EXIT_SUCCESS);}

if the applications are C#, you can use ClickOnce deployment, which is a good option if you can't guarentee the user will have the app, however you'll have to re-build the apps with deployment options and grab some boilerplate code from each project.

You can also use Javascript.

Or you can register an application to handle a new web protocol you can define. This could also be an "app selection" protocol, so each time an app is clicked it would link to a page on your new protocol, all handling of this protocol is then passed to your "selection app" which uses arguments to find and launch an app on the clients PC.

I'm a fan of the Find-In-Files dialog in Notepad++. Bonus: It's free.

Here is usage of Math.PI to find circumference of circle and Area First we take Radius as a string in Message Box and convert it into integer

public class circle {

    public static void main(String[] args) {
        // TODO code application logic here

        String rad;

        float radius,area,circum;

       rad = JOptionPane.showInputDialog("Enter the Radius of circle:");

        radius = Integer.parseInt(rad);
        area = (float) (Math.PI*radius*radius);
        circum = (float) (2*Math.PI*radius);

        JOptionPane.showMessageDialog(null, "Area: " + area,"AREA",JOptionPane.INFORMATION_MESSAGE);
        JOptionPane.showMessageDialog(null, "circumference: " + circum, "Circumfernce",JOptionPane.INFORMATION_MESSAGE);
    }

}

It will group by the column position you put after the group by clause.

for example if you run 'SELECT SALESMAN_NAME, SUM(SALES) FROM SALES GROUP BY 1' it will group by SALESMAN_NAME.

One risk on doing that is if you run 'Select *' and for some reason you recreate the table with columns on a different order, it will give you a different result than you would expect.

If you know the group id of X, you can use this command to redownload all of X and it's dependencies

mvn clean dependency:purge-local-repository -DresolutionFuzziness=org.id.of.x

It does the same thing as the other answers that propose using dependency:purge-local-repository, but it only deletes and redownloads everything related to X.

Here is one possible solution of first part

#include<iostream>

using namespace std;
int main()
{
    int marks[][4] = {
                      10, 20, 30, 50,
                      40, 50, 60, 60,
                      10, 20, 10, 70
                     };

int rows =  sizeof(marks)/sizeof(marks[0]);
int cols = sizeof(marks)/(sizeof(int)*rows);


    for(int i=0; i<rows; i++)
    {
        for(int j=0; j<cols; j++)
        {
            cout<<marks[i][j]<<" ";
        }
        cout<<endl;
    }



    return 0;
}

Try this......pass in the number to be rounded off and it will round off to the nearest tenth.hope it helps....

round($num, 1);

Many ways. DON'T use the most obvious one (%s with %) in real code, it's open to attacks.

Here copy-paste'd from pydoc of sqlite3:

# Never do this -- insecure!
symbol = 'RHAT'
c.execute("SELECT * FROM stocks WHERE symbol = '%s'" % symbol)

# Do this instead
t = ('RHAT',)
c.execute('SELECT * FROM stocks WHERE symbol=?', t)
print c.fetchone()

# Larger example that inserts many records at a time
purchases = [('2006-03-28', 'BUY', 'IBM', 1000, 45.00),
             ('2006-04-05', 'BUY', 'MSFT', 1000, 72.00),
             ('2006-04-06', 'SELL', 'IBM', 500, 53.00),
            ]
c.executemany('INSERT INTO stocks VALUES (?,?,?,?,?)', purchases)

More examples if you need:

# Multiple values single statement/execution
c.execute('SELECT * FROM stocks WHERE symbol=? OR symbol=?', ('RHAT', 'MSO'))
print c.fetchall()
c.execute('SELECT * FROM stocks WHERE symbol IN (?, ?)', ('RHAT', 'MSO'))
print c.fetchall()
# This also works, though ones above are better as a habit as it's inline with syntax of executemany().. but your choice.
c.execute('SELECT * FROM stocks WHERE symbol=? OR symbol=?', 'RHAT', 'MSO')
print c.fetchall()
# Insert a single item
c.execute('INSERT INTO stocks VALUES (?,?,?,?,?)', ('2006-03-28', 'BUY', 'IBM', 1000, 45.00))

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

I was having a similar issue but none of these fixes worked. The problem was that my button was not yet on the page. The fix for this ended up being going from this:

//Bad code.
var btn = document.createElement('button');
btn.onClick = function() {  console.log("hey");  }

to this:

//Working Code.  I don't like it, but it works. 
var btn = document.createElement('button');
var wrapper = document.createElement('div');
wrapper.appendChild(btn);

document.body.appendChild(wrapper);
var buttons = wrapper.getElementsByTagName("BUTTON");
buttons[0].onclick = function(){  console.log("hey");  }

I have no clue at all why this works. Adding the button to the page and referring to it any other way did not work.

I wrote an extended Iterable class that support applying functional algorithms without copying the collection content.

Usage:

List<Integer> myList = new ArrayList<Integer>(){ 1, 2, 3, 4, 5 }

Iterable<Integer> filtered = Iterable.wrap(myList).select(new Predicate1<Integer>()
{
    public Boolean call(Integer n) throws FunctionalException
    {
        return n % 2 == 0;
    }
})

for( int n : filtered )
{
    System.out.println(n);
}

The code above will actually execute

for( int n : myList )
{
    if( n % 2 == 0 ) 
    {
        System.out.println(n);
    }
}

You can use a $where. Just be aware it will be fairly slow (has to execute Javascript code on every record) so combine with indexed queries if you can.

db.T.find( { $where: function() { return this.Grade1 > this.Grade2 } } );

or more compact:

db.T.find( { $where : "this.Grade1 > this.Grade2" } );

UPD for mongodb v.3.6+

you can use $expr as described in recent answer

I used starikovs' solution. I started with a bash window and gave the commands

cd ~
touch .bashrc

Then I found the .bashrc file in windows explorer, opened it with notepad++ and added

PATH=$PATH:"C:\Program Files (x86)\Notepad++"

so that bash knows where to find Notepad++. (Having Notepad++ in the bash PATH is a useful thing on its own!) Then I pasted his line

git config --global core.editor "notepad++.exe -multiInst"

into a bash window. I started a new bash window for a git repository to test things with the command

git rebase -i HEAD~10

and the file opened in Notepad++ as hoped.

JSONArray jsonChildArray = (JSONArray) jsonChildArray.get("LanguageLevels");
    JSONObject secObject = (JSONObject) jsonChildArray.get(1);

I think this should work, but i do not have the possibility to test it at the moment..

Yes you can achive this by ajax post method. on server side you can use httphandler. So we are not using any server controls as per your requirement.

with ajax you can show the upload progress also.

you will have to read the file as a inputstream.

using (FileStream fs = File.Create("D:\\_Workarea\\" + fileName))
    {
        Byte[] buffer = new Byte[32 * 1024];
        int read = context.Request.GetBufferlessInputStream().Read(buffer, 0, buffer.Length);
        while (read > 0)
        {
            fs.Write(buffer, 0, read);
            read = context.Request.GetBufferlessInputStream().Read(buffer, 0, buffer.Length);
        }
    } 

Sample Code

function sendFile(file) {              
        debugger;
        $.ajax({
            url: 'handler/FileUploader.ashx?FileName=' + file.name, //server script to process data
            type: 'POST',
            xhr: function () {
                myXhr = $.ajaxSettings.xhr();
                if (myXhr.upload) {
                    myXhr.upload.addEventListener('progress', progressHandlingFunction, false);
                }
                return myXhr;
            },
            success: function (result) {                    
                //On success if you want to perform some tasks.
            },
            data: file,
            cache: false,
            contentType: false,
            processData: false
        });
        function progressHandlingFunction(e) {
            if (e.lengthComputable) {
                var s = parseInt((e.loaded / e.total) * 100);
                $("#progress" + currFile).text(s + "%");
                $("#progbarWidth" + currFile).width(s + "%");
                if (s == 100) {
                    triggerNextFileUpload();
                }
            }
        }
    }

Probably there's something wrong with the input values for X and/or T. The function from the question works ok:

import numpy as np
from math import e

def sigmoid(X, T):
  return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))

X = np.array([[1, 2, 3], [5, 0, 0]])
T = np.array([[1, 2], [1, 1], [4, 4]])

print(X.dot(T))
# Just to see if values are ok
print([1. / (1. + e ** el) for el in [-5, -10, -15, -16]])
print()
print(sigmoid(X, T))

Result:

[[15 16]
 [ 5 10]]

[0.9933071490757153, 0.9999546021312976, 0.999999694097773, 0.9999998874648379]

[[ 0.99999969  0.99999989]
 [ 0.99330715  0.9999546 ]]

Probably it's the dtype of your input arrays. Changing X to:

X = np.array([[1, 2, 3], [5, 0, 0]], dtype=object)

Gives:

Traceback (most recent call last):
  File "/[...]/stackoverflow_sigmoid.py", line 24, in <module>
    print sigmoid(X, T)
  File "/[...]/stackoverflow_sigmoid.py", line 14, in sigmoid

If someone finds this question like I did, then I'll post my solution which works on Django 2.0:

This tag assigns some settings.py variable value to template's variable:

Usage: {% get_settings_value template_var "SETTINGS_VAR" %}

app/templatetags/my_custom_tags.py:

from django import template
from django.conf import settings

register = template.Library()

class AssignNode(template.Node):
    def __init__(self, name, value):
        self.name = name
        self.value = value

    def render(self, context):
        context[self.name] = getattr(settings, self.value.resolve(context, True), "")
        return ''

@register.tag('get_settings_value')
def do_assign(parser, token):
    bits = token.split_contents()
    if len(bits) != 3:
        raise template.TemplateSyntaxError("'%s' tag takes two arguments" % bits[0])
    value = parser.compile_filter(bits[2])
    return AssignNode(bits[1], value)

Your template:

{% load my_custom_tags %}

# Set local template variable:
{% get_settings_value settings_debug "DEBUG" %}

# Output settings_debug variable:
{{ settings_debug }}

# Use variable in if statement:
{% if settings_debug %}
... do something ...
{% else %}
... do other stuff ...
{% endif %}

See Django's documentation how to create custom template tags here: https://docs.djangoproject.com/en/2.0/howto/custom-template-tags/

Try to use a for each

for ( Direction direction : Direction.values()){
  System.out.println(direction.toString());
}

If you run the above as they are, they will appear to run simultaenously.

Here's some test code:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script>
$(function () {
    $('#first').animate({ width: 200 }, 200);
    $('#second').animate({ width: 600 }, 200);
});
</script>
<div id="first" style="border:1px solid black; height:50px; width:50px"></div>
<div id="second" style="border:1px solid black; height:50px; width:50px"></div>

In neither case is the "syntax malformed". It's the semantics that are wrong. Hence, IMHO a 400 is inappropriate. Instead, it would be appropriate to return a 200 along with some kind of error object such as { "error": { "message": "Unknown request keyword" } } or whatever.

Consider the client processing path(s). An error in syntax (e.g. invalid JSON) is an error in the logic of the program, in other words a bug of some sort, and should be handled accordingly, in a way similar to a 403, say; in other words, something bad has gone wrong.

An error in a parameter value, on the other hand, is an error of semantics, perhaps due to say poorly validated user input. It is not an HTTP error (although I suppose it could be a 422). The processing path would be different.

For instance, in jQuery, I would prefer not to have to write a single error handler that deals with both things like 500 and some app-specific semantic error. Other frameworks, Ember for one, also treat HTTP errors like 400s and 500s identically as big fat failures, requiring the programmer to detect what's going on and branch depending on whether it's a "real" error or not.

Assuming their updates are on master, and you are on the branch you want to merge the changes into.

git remote add origin https://github.com/<github-username>/<repo-name>.git
git pull origin master

Also note that you will then want to push the merge back to your copy of the repository:

git push origin master

Which Mac version are you using? try these paths

Comment as an answer:

if (timetime[0].value)

This works because any variable in JS can be evaluated as a boolean, so this will generally catch things that are empty, null, or undefined.

This will happen from time to time either when a connection times out or when a remote host terminates their connection (closed application, computer shutdown, etc). You can avoid this by managing sockets yourself and handling disconnections in your application via its communications protocol and then calling shutdownInput and shutdownOutput to clear up the session.

According to the stack trace, your issue is that your app cannot find org.apache.commons.dbcp.BasicDataSource, as per this line:

java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

I see that you have commons-dbcp in your list of jars, but for whatever reason, your app is not finding the BasicDataSource class in it.

it needs ONLY to popup when inside a vm, so technically, there should be some code like:

if %machine_type% == virtual_machine then
   echo message box code
else
   continue normal installation code

MySql decimal types are a little bit more complicated than just left-of and right-of the decimal point.

The first argument is precision, which is the number of total digits. The second argument is scale which is the maximum number of digits to the right of the decimal point.

Thus, (4,2) can be anything from -99.99 to 99.99.

As for why you're getting 99.99 instead of the desired 3.80, the value you're inserting must be interpreted as larger than 99.99, so the max value is used. Maybe you could post the code that you are using to insert or update the table.

Edit

Corrected a misunderstanding of the usage of scale and precision, per http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html.

If you are using jQuery you can easily check the type of any element.

    function(elementID){    
    var type = $(elementId).attr('type');
    if(type == "text") //inputBox
     console.log("input text" + $(elementId).val().size());
   }

similarly you can check the other types and take appropriate action.

You've got the right idea, so here's how to go ahead: the onclick handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:

<script type="text/javascript">
function recp(id) {
  $('#myStyle').load('data.php?id=' + id);
}
</script>

<a href="#" onClick="recp('1')" > One   </a>
<a href="#" onClick="recp('2')" > Two   </a>
<a href="#" onClick="recp('3')" > Three </a>

<div id='myStyle'>
</div>

Then you put your PHP code into a separate file: (I've called it data.php in the above example)

<?php
  require ('myConnect.php');     
  $id = $_GET['id'];
  $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
  if( mysql_num_rows($results) > 0 )
  {
   $row = mysql_fetch_array( $results );
   echo $row['para'];
  }
?>

setTimeout(function() {
     $('.message').hide();
}, 2000);

This will hide the '.message' div after 2 seconds.

And yet another option: https://github.com/apptik/jus

• It is modular like Volley, but more extended and documentation is improving, supporting different HTTP stacks and converters out of the box
• It has a module to generate server API interface mappings like Retrofit
• It also has JavaRx support

And many other handy features like markers, transformers, etc.

You can use NLTK method for it.

This will find both '1' and 'One' in the text:

import nltk 

def existence_of_numeric_data(text):
    text=nltk.word_tokenize(text)
    pos = nltk.pos_tag(text)
    count = 0
    for i in range(len(pos)):
        word , pos_tag = pos[i]
        if pos_tag == 'CD':
            return True
    return False

existence_of_numeric_data('We are going out. Just five you and me.')

You can make use of PieceLabel plugin for Chart.js.

{ pieceLabel: { mode: 'percentage', precision: 2 } }

Demo | Documentation

The plugin appears to have a new location (and name): Demo Docs.

You can put them in the Application:

Application["GlobalVar"] = 1234;

They are only global within the current IIS / Virtual applicition. This means, on a webfarm they are local to the server, and within the virtual directory that is the root of the application.

As documented in /usr/src/linux/Documentation/block/switching-sched.txt, the I/O scheduler on any particular block device can be changed at runtime. There may be some latency as the previous scheduler's requests are all flushed before bringing the new scheduler into use, but it can be changed without problems even while the device is under heavy use.

# cat /sys/block/hda/queue/scheduler
noop deadline [cfq]
# echo anticipatory > /sys/block/hda/queue/scheduler
# cat /sys/block/hda/queue/scheduler
noop [deadline] cfq

Ideally, there would be a single scheduler to satisfy all needs. It doesn't seem to exist yet. The kernel often doesn't have enough knowledge to choose the best scheduler for your workload:

• noop is often the best choice for memory-backed block devices (e.g. ramdisks) and other non-rotational media (flash) where trying to reschedule I/O is a waste of resources
• deadline is a lightweight scheduler which tries to put a hard limit on latency
• cfq tries to maintain system-wide fairness of I/O bandwidth

The default was anticipatory for a long time, and it received a lot of tuning, but was removed in 2.6.33 (early 2010). cfq became the default some while ago, as its performance is reasonable and fairness is a good goal for multi-user systems (and even single-user desktops). For some scenarios -- databases are often used as examples, as they tend to already have their own peculiar scheduling and access patterns, and are often the most important service (so who cares about fairness?) -- anticipatory has a long history of being tunable for best performance on these workloads, and deadline very quickly passes all requests through to the underlying device.

Try

Dim connectionString AS String = "Server=my_server;Database=name_of_db;User Id=user_name;Password=my_password"

And replace my_server, name_of_db, user_name and my_password with your values.

then Using sqlCon = New SqlConnection(connectionString) should work

also I think your SQL is wrong, it should be SET clickCount= clickCount + 1 I think.

And on a general note, the page you link to has a link called Connection String which shows you how to do this.

You can also combine two lists (say a,b) using the '+' operator. For example,

a = [1,2,3,4]
b = [4,5,6,7]
c = a + b

Output:
>>> c
[1, 2, 3, 4, 4, 5, 6, 7]

Well, if in the HTML you import a script...

<script type="text/javascript" src="//stier.linuxfaq.org/ip.php"></script>

You can then use the variable userIP (which would be the visitor's IP address) anywhere on the page.

To redirect: <script>if (userIP == "555.555.555.55") {window.location.replace("http://192.168.1.3/flex-start/examples/navbar-fixed-top/");}</script>

Or to show it on the page: document.write (userIP);

DISCLAIMER: I am the author of the script I said to import. The script comes up with the IP by using PHP. The source code of the script is below.

<?php //Gets the IP address $ip = getenv("REMOTE_ADDR") ; Echo "var userIP = '" . $ip . "';"; ?>

Create key-value pairs within a foreach like this:

function createOfferUrlArray($Offer) {
    $offerArray = array();

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

    return $offerArray;
}

You can download files with the WebClient class:

using System.Net;

using (WebClient client = new WebClient ()) // WebClient class inherits IDisposable
{
    client.DownloadFile("http://yoursite.com/page.html", @"C:\localfile.html");

    // Or you can get the file content without saving it
    string htmlCode = client.DownloadString("http://yoursite.com/page.html");
}

Use transform: rotate(90deg):

#container_2 {_x000D_
    border: 1px solid;_x000D_
    padding: .5em;_x000D_
    width: 5em;_x000D_
    height: 5em;_x000D_
    transition: .3s all;  /* rotate gradually instead of instantly */_x000D_
}_x000D_
_x000D_
#container_2:hover {_x000D_
    -webkit-transform: rotate(90deg);  /* to support Safari and Android browser */_x000D_
    -ms-transform: rotate(90deg);      /* to support IE 9 */_x000D_
    transform: rotate(90deg);_x000D_
}

<div id="container_2">This box should be rotated 90&deg; on hover.</div>

Click "Run code snippet", then hover over the box to see the effect of the transform.

Realistically, no other prefixed entries are needed. See Can I use CSS3 Transforms?

I have scopes for this, hope it help somebody. https://laravel.com/docs/master/eloquent#local-scopes

public function scopeWhereLike($query, $column, $value)
{
    return $query->where($column, 'like', '%'.$value.'%');
}

public function scopeOrWhereLike($query, $column, $value)
{
    return $query->orWhere($column, 'like', '%'.$value.'%');
}

Usage:

$result = BookingDates::whereLike('email', $email)->orWhereLike('name', $name)->get();

Depending on if your are running X64 you might need to clean up a couple more spots. Just cleaning up my user directory was not enough.
