I&#39;m working on an Xcode 7 Playground that has many things running at once. Whenever I make an edit, it refreshes, restarts what was running and runs through the entire code again. That crashes my playground around every 15 minutes. Is there a way to prevent playgrounds from automatically running whenever I make an edit?

How do you prevent Xcode 7 Playgrounds from automatically running?

Ok.  I have looked EVERYWHERE and my little brain just can&#39;t understand a better way to refresh an activity.  Any suggestions that I can understand would be great.  :)

Here is the java code:

    package com.dge.dges;
    
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    import android.webkit.WebView;
    import android.widget.Button;
    
    public class dgeActivity extends Activity {

        WebView mWebView;

        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
    
            mWebView = (WebView) findViewById(R.id.webview);
            mWebView.getSettings();
            mWebView.loadUrl(&quot;http://www.websitehere.php&quot;);
            
            Button newButton = (Button)findViewById(R.id.new_button);
            newButton.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    Intent intent = new Intent(dgeActivity.this, dgeActivity.class);
                    startActivity(intent);
                }
            });
        }
    }

And here is the `main.xml`


    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;RelativeLayout
        xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:id=&quot;@+id/RelativeLayout&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;fill_parent&quot;
        android:background=&quot;#000000&quot;&gt;
    
        &lt;WebView
            android:id=&quot;@+id/webview&quot;
            android:layout_width=&quot;fill_parent&quot; 
            android:layout_height=&quot;wrap_content&quot;
            android:scrollbars=&quot;none&quot;/&gt;

        &lt;Button
            android:id=&quot;@+id/new_button&quot;
            android:layout_width=&quot;fill_parent&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:layout_alignParentBottom=&quot;true&quot;
            android:layout_centerHorizontal=&quot;true&quot;
            android:text=&quot;Refresh&quot;/&gt;

    &lt;/RelativeLayout&gt;


I don&#39;t like the idea of just re-stacking activity after activity.  There has to be an easier way to refresh the webview.  Please help.  :)


Is there a better way to refresh WebView?

I have often experienced while developing my web applications that pressing &lt;kbd&gt;F5&lt;/kbd&gt; or refresh doesn&#39;t produce or refresh the proper result. But when we hit &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;F5&lt;/kbd&gt; it generates the correct result. What is the basic difference between simple &lt;kbd&gt;F5&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;F5&lt;/kbd&gt;?

I have often also experienced that pressing simple &lt;kbd&gt;F5&lt;/kbd&gt; and pressing the &lt;kbd&gt;Refresh&lt;/kbd&gt; button in the browser also generate different results.

What is the basic difference among all these requests?

Is there a Page.Refresh type of command to refresh a page?

I don&#39;t want to redirect to the page or refresh in JavaScript.


Refresh Page C# ASP.NET

The code below displays a Google map and search results when you enter an address and hit the submit button.  I&#39;ve been playing with it to try
and force the page to completely refresh or reload once you hit the submit button.  But I can&#39;t get it to work right.  It loads the results &quot;in page,&quot; but I&#39;d like the page to completely refresh when the results load, like when you hit the back button on your browser.  Hope that makes sense.

How to force page refreshes or reloads in jQuery?

I am using a [mat-table](https://material.angular.io/components/table/overview) to list the content of the users chosen languages. They can also add new languages using dialog panel. After they added a language and returned back. I want my datasource to refresh to show the changes they made.

If you change a dropdown and refresh the page, Firefox seems to ignore the selected attribute.

    &lt;option selected=&quot;selected&quot; value=&quot;Test&quot;&gt;Test&lt;/option&gt;

It will in fact select the option you had previously selected (before the refresh).  This ends up being a problem for me since there is an event triggered on the dropdown which changes other things.  

Is there a way to make firefox stop this behavior (other than firing another event when the page loads)?

Once the user is on my page, I do not want him to refresh the page.

1. Anytime, the user hits &lt;kbd&gt;F5&lt;/kbd&gt; or refresh button on top. He should get an alert saying

2. Also if the user opens a new tab and tries to access the same url in prev tab he should get an alert

This is my jTable 

    private JTable getJTable() {
		String[] colName = { &quot;Name&quot;, &quot;Email&quot;, &quot;Contact No. 1&quot;, &quot;Contact No. 2&quot;,
				&quot;Group&quot;, &quot;&quot; };
		if (jTable == null) {
			jTable = new JTable() {
				public boolean isCellEditable(int nRow, int nCol) {
					return false;
				}
			};
		}
		DefaultTableModel contactTableModel = (DefaultTableModel) jTable
				.getModel();
		contactTableModel.setColumnIdentifiers(colName);
		jTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
		return jTable;
	}

I will call this method to retrieve the data from database and put it into table model

    public void setUpTableData() {
		DefaultTableModel tableModel = (DefaultTableModel) jTable.getModel();
		ArrayList&lt;Contact&gt; list = new ArrayList&lt;Contact&gt;();
		if (!con.equals(&quot;&quot;))
			list = sql.getContactListsByGroup(con);
		else
			list = sql.getContactLists();
		for (int i = 0; i &lt; list.size(); i++) {
			String[] data = new String[7];
			
				data[0] = list.get(i).getName();
				data[1] = list.get(i).getEmail();
				data[2] = list.get(i).getPhone1();
				data[3] = list.get(i).getPhone2();
				data[4] = list.get(i).getGroup();
				data[5] = list.get(i).getId();
			
			tableModel.addRow(data);
		}
		jTable.setModel(tableModel);
	}

Currently I was using this method to refresh the table after updating the table data. I will first clear the table 

    DefaultTableModel tableModel = (DefaultTableModel) jTable.getModel();
    tableModel.setRowCount(0);

and then restructure the table model again so it will refresh the jTable. But I was thinking is there any best practices or better way to do that?

Refresh (reload) a page once using jQuery?

I am accessing a link on my site that will provide a new image each time it is accessed.

The issue I am running into is that if I try to load the image in the background and then update the one on the page, the image doesn&#39;t change--though it is updated when I reload the page.

    newImage.src = &quot;http://localhost/image.jpg&quot;;

		newImage = new Image();
		number++;
		newImage.src = &quot;http://localhost/image/id/image.jpg?time=&quot; + new Date();

Is there a standard for what actions &lt;kbd&gt;F5&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;F5&lt;/kbd&gt; trigger in web browsers?

I once did experiment in IE6 and Firefox 2.x. The &lt;kbd&gt;F5&lt;/kbd&gt;  refresh would trigger a HTTP request sent to the server with an `If-Modified-Since` header, while &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;F5&lt;/kbd&gt; would not have such a header. In my understanding, &lt;kbd&gt;F5&lt;/kbd&gt;  will try to utilize cached content as much as possible, while &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;F5&lt;/kbd&gt; is intended to abandon all cached content and just retrieve all content from the servers again. 

But today, I noticed that in some of the latest browsers (Chrome, IE8) it doesn&#39;t work in this way anymore. Both &lt;kbd&gt;F5&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;F5&lt;/kbd&gt; send the `If-Modified-Since` header. 

So how is this supposed to work, or (if there is no standard) how do the major browsers differ in how they implement these refresh features?

            test.close();
    }

With this however, everytime I need to refresh the data set, I need to keep running this block of code (which gets a bit difficult inside an onClick() for a button due to &quot;this&quot; not being available.

Is this the best way to refresh the data set, or should I look towards removing the .close and issue an adapter.notifyDataSetChanged()? If I do this, sometimes I get a force close as (and I can&#39;t remember at the moment) but sometimes it cannot Delete properly - I think this may be because the database is currently open and it tries to open again.

Should we also be declaring the variables for the Cursors, DatabaseHelpers and Adapter in the Class (outside of the OnCreate) so that they are accessible to all the functions?

I realise this is just poor programming at this stage, but Im trying to get some pointers as to the best way of doing things.

Best Way to Refresh Adapter/ListView on Android

I want to reload a page using:

    window.location.reload(true); 

But I receive the POSTDATA warning because the refresh function want to resend previous POST form data. How can I refresh my page without this warning?

UPDATED: I have no control of the project! I can&#39;t workaround the POST itself!

The Playground in Xcode automatically updates as you type, but I can&#39;t figure out how to get the Playground to &quot;re-compile&quot;.

In many cases this wouldn&#39;t matter, but if you&#39;re writing code that generates or uses random values it can be useful to run it a few times to make sure it&#39;s working. Is there any way to get the playground to reset / refresh / re-run?

Seen a few questions asking how to stop the Playground from auto-updating, but nothing for the opposite.

Easiest way to do this seems to be to just edit the code (add and remove a space), or put in some kind of a loop... Just wondering if there&#39;s a menu shortcut etc.
