I could successfully integrate Pagination in

spring-data-jpa-2.1.6

as follows.

@Query(
 value = “SELECT * FROM Users”, 
 countQuery = “SELECT count(*) FROM Users”, 
 nativeQuery = true)
Page<User> findAllUsersWithPagination(Pageable pageable);

Your encoded text is [B@6499375d. That is not Base64, something went wrong while encoding. That decoding code looks good.

Use this code to convert the byte[] to a String before adding it to the URL:

String encodedEmailString = new String(encodedEmail, "UTF-8");
// ...
String confirmLink = "Complete your registration by clicking on following"
    + "\n<a href='" + confirmationURL + encodedEmailString + "'>link</a>";

The Exception it self says it all java.lang.ClassNotFoundException: org.json.JSONObject

You have not added the necessary jar file which will be having org.json.JSONObject class to your classpath.

You can Download it From Here

It's almost always advisable to not use scriptlets in your JSP. They're considered bad form. Instead, try using JSTL (JSP Standard Tag Library) combined with EL (Expression Language) to run the conditional logic you're trying to do. As an added benefit, JSTL also includes other important features like looping.

Instead of:

<%String user=request.getParameter("user"); %>
<%if(user == null || user.length() == 0){
    out.print("I see! You don't have a name.. well.. Hello no name");   
}
else {%>
    <%@ include file="response.jsp" %>
<% } %>

Use:

<c:choose>
    <c:when test="${empty user}">
        I see!  You don't have a name.. well.. Hello no name
    </c:when>
    <c:otherwise>
        <%@ include file="response.jsp" %>
    </c:otherwise>
</c:choose>

Also, unless you plan on using response.jsp somewhere else in your code, it might be easier to just include the html in your otherwise statement:

<c:otherwise>
    <h1>Hello</h1>
    ${user}
</c:otherwise>

Also of note. To use the core tag, you must import it as follows:

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

You want to make it so the user will receive a message when the user submits a username. The easiest way to do this is to not print a message at all when the "user" param is null. You can do some validation to give an error message when the user submits null. This is a more standard approach to your problem. To accomplish this:

In scriptlet:

<% String user = request.getParameter("user");
   if( user != null && user.length() > 0 ) {
       <%@ include file="response.jsp" %>
   }
%>

In jstl:

<c:if test="${not empty user}">
    <%@ include file="response.jsp" %>
</c:if>

you can't call sendRedirect(), after you have already used forward(). So, you get that exception.

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.

In test.jsp

Create a javascript

<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
} 
</script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to

Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.

To do that i would highly recommendation to use session!

So what you want to do is in your servlet:

session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);

than in the test.jsp

<%
session.setMaxInactiveInterval(2);
%>

 <script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
    if (Msg != "null") {
 function alertName(){
 alert("Form has been submitted");
 } 
 }
 </script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

So everytime you submit that form a session will be pass on! If session is not null the function will run!

I think your issue may be in the url pattern. Changing

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

and

<form action="/Register" method="post">

may fix your problem

I am trying to Understand your Question and it seems that you want the values in the first JSP to be available in the Second JSP.

1. It is very bad Habit to Place Java Code snippets Inside JSP file, so that code snippet should go to a servlet.

2. Pick the values in a servlet ie.

   String username = request.getParameter("username");
   String password = request.getParameter("password");
   

3. Then Store the Values inside the Session:

   HttpSession sess = request.getSession(); 
   sess.setAttribute("username", username);
   sess.setAttribute("password", password);
   

4. These values Will be available anywhere in the Application as long as the session is valid.

   HttpSession sess = request.getSession(false); //use false to use the existing session
   sess.getAttribute("username");//this will return username anytime in the session
   sess.getAttribute("password");//this will return password Any time in the session
   

I hope this is what you wanted to know, but please do not use code snippets in the JSP. You can always get the values into the JSP using jstl in the JSPs:

 ${username}//this will give you the username in the JSP
 ${password}// this will give you the password in the JSP

use this code it is working

// index.jsp or login.jsp

For those who use Tomcat with Bitronix, this will fix the problem:

The error indicates that no handler could be found for your datasource 'jdbc/mydb', so you'll need to make sure your tomcat server refers to your bitronix configuration files as needed.

In case you're using btm-config.properties and resources.properties files to configure the datasource, specify these two JVM arguments in tomcat:

(if you already used them, make sure your references are correct):

• btm.root
• bitronix.tm.configuration

e.g.

-Dbtm.root="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59" 
-Dbitronix.tm.configuration="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59\conf\btm-config.properties" 

Now, restart your server and check the log.

Suppose we want to pass three values(u1,u2,u3) from say 'show.jsp' to another page say 'display.jsp' Make three hidden text boxes and a button that is click automatically(using javascript). //Code to written in 'show.jsp'

<body>
<form action="display.jsp" method="post">
 <input type="hidden" name="u1" value="<%=u1%>"/>
 <input type="hidden" name="u2" value="<%=u2%>" />
 <input type="hidden" name="u3" value="<%=u3%>" />
 <button type="hidden" id="qq" value="Login" style="display: none;"></button>
</form>
  <script type="text/javascript">
     document.getElementById("qq").click();
  </script>
</body>

// Code to be written in 'display.jsp'

 <% String u1 = request.getParameter("u1").toString();
    String u2 = request.getParameter("u2").toString();
    String u3 = request.getParameter("u3").toString();
 %>

If you want to use these variables of servlets in javascript then simply write

<script type="text/javascript">
 var a=<%=u1%>;
</script>

Hope it helps :)

In here:

    if (ValidationUtils.isNullOrEmpty(lastName)) {
        registrationErrors.add(ValidationErrors.LAST_NAME);
    }
    if (!ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

you check for null or empty value on lastname, but in isEmailValid you don't check for empty value. Something like this should do

    if (ValidationUtils.isNullOrEmpty(email) || !ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

or better yet, fix your ValidationUtils.isEmailValid() to cope with null email values. It shouldn't crash, it should just return false.

In addition to what Angular University said above you may want to use @Import to aggregate @Configuration classes to the other class (AuthenticationController in my case) :

@Import(SecurityConfig.class)
@RestController
public class AuthenticationController {
@Autowired
private AuthenticationManager authenticationManager;
//some logic
}

Spring doc about Aggregating @Configuration classes with @Import: link

Remove conn.commit from Register.java

In your jsp change action to :<form name="registrationform" action="Register" method="post">

Very important point here to understand , the SurfaceView size must be the same as the camera parameters size , it means they have the same aspect ratio then the Stretch effect will go off .

You have to get the correct supported camera preview size using params.getSupportedPreviewSizes() choose one of them and then change your SurfaceView and its holders to this size.

In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:

httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

NullPointerException with JSP can also happen if:

A getter returns a non-public inner class.

This code will fail if you remove Getters's access modifier or make it private or protected.

JAVA:

package com.myPackage;
public class MyClass{ 
    //: Must be public or you will get:
    //: org.apache.jasper.JasperException: 
    //: java.lang.NullPointerException
    public class Getters{
        public String 
        myProperty(){ return(my_property); }
    };;

    //: JSP EL can only access functions:
    private Getters _get;
    public  Getters  get(){ return _get; }

    private String 
    my_property;

    public MyClass(String my_property){
        super();
        this.my_property    = my_property;
        _get = new Getters();
    };;
};;

JSP

<%@ taglib uri   ="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import="com.myPackage.MyClass" %>
<%
    MyClass inst = new MyClass("[PROP_VALUE]");
    pageContext.setAttribute("my_inst", inst ); 
%><html lang="en"><body>
    ${ my_inst.get().myProperty() }
</body></html>

See JavaDoc:

month - the value used to set the MONTH calendar field. Month value is 0-based. e.g., 0 for January.

So, the month you set is the first month of next year.

In Eclipse , rightclick on your application

Run As -> Run configurations -> select your server from type filter text box

Then in Classpath under Bootstrap Entries add your classes12.jar File and Click on Apply.
Now, run the file...... This worked for me !!

Simple answer:
Use getReader() to read the body of the request

More info:
There are two methods for reading the data in the body:

1. getReader() returns a BufferedReader that will allow you to read the body of the request.

2. getInputStream() returns a ServletInputStream if you need to read binary data.

Note from the docs: "[Either method] may be called to read the body, not both."

Go through C:\apache-tomcat-7.0.47\lib path (this path may be differ based on where you installed the Tomcat server) then past ojdbc14.jar if its not contain.

Then restart the server in eclipse then run your app on server

Date d1 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date1));
Date d2 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date2));

long diff = d2.getTime() - d1.getTime();

System.out.println("Difference between  " + d1 + " and "+ d2+" is "
        + (diff / (1000 * 60 * 60 * 24)) + " days.");

If you have same error handling logic for different method handlers, then you would end up with lots of handlers with following code pattern:

if (validation.hasErrors()) {
  // do error handling
}
else {
  // do the actual business logic
}

Suppose you're creating RESTful services and want to return 400 Bad Request along with error messages for every validation error case. Then, the error handling part would be same for every single REST endpoint that requires validation. Repeating that very same logic in every single handler is not so DRYish!

One way to solve this problem is to drop the immediate BindingResult after each To-Be-Validated bean. Now, your handler would be like this:

@RequestMapping(...)
public Something doStuff(@Valid Somebean bean) { 
    // do the actual business logic
    // Just the else part!
}

This way, if the bound bean was not valid, a MethodArgumentNotValidException will be thrown by Spring. You can define a ControllerAdvice that handles this exception with that same error handling logic:

@ControllerAdvice
public class ErrorHandlingControllerAdvice {
    @ExceptionHandler(MethodArgumentNotValidException.class)
    public SomeErrorBean handleValidationError(MethodArgumentNotValidException ex) {
        // do error handling
        // Just the if part!
    }
}

You still can examine the underlying BindingResult using getBindingResult method of MethodArgumentNotValidException.

You aren't really using the doGet() method. When you're opening the page, it issues a GET request, not POST.

Try changing doPost() to service() instead... then you're using the same method to handle GET and POST requests.

...

You can pass multiple parameters as "?param1=value1&param2=value2"

But it's not secure. It's vulnerable to Cross Site Scripting (XSS) Attack.

Your parameter can be simply replaced with a script.

Have a look at this article and article

You can make it secure by using API of StringEscapeUtils

static String   escapeHtml(String str) 
          Escapes the characters in a String using HTML entities.

Even using https url for security without above precautions is not a good practice.

Have a look at related SE question:

Is URLEncoder.encode(string, "UTF-8") a poor validation?

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

To get the value from the servlet from POST command, you can follow the approach as explained on this post by using request.getParameter(key) format which will return the value you want.

I too had the same issue and I believe the code below is more simple and it is working for me,

public class MultiReadHttpServletRequest extends  HttpServletRequestWrapper {

 private String _body;

public MultiReadHttpServletRequest(HttpServletRequest request) throws IOException {
   super(request);
   _body = "";
   BufferedReader bufferedReader = request.getReader();           
   String line;
   while ((line = bufferedReader.readLine()) != null){
       _body += line;
   }
}

@Override
public ServletInputStream getInputStream() throws IOException {
   final ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(_body.getBytes());
   return new ServletInputStream() {
       public int read() throws IOException {
           return byteArrayInputStream.read();
       }
   };
}

@Override
public BufferedReader getReader() throws IOException {
   return new BufferedReader(new InputStreamReader(this.getInputStream()));
}
}

in the filter java class,

HttpServletRequest properRequest = ((HttpServletRequest) req);
MultiReadHttpServletRequest wrappedRequest = new MultiReadHttpServletRequest(properRequest);
req = wrappedRequest;
inputJson = IOUtils.toString(req.getReader());
System.out.println("body"+inputJson);

Please let me know if you have any queries

The HttpParams interface isn't there for specifying query string parameters, it's for specifying runtime behaviour of the HttpClient object.

If you want to pass query string parameters, you need to assemble them on the URL yourself, e.g.

new HttpGet(url + "key1=" + value1 + ...);

Remember to encode the values first (using URLEncoder).

$request = Request::createFromGlobals();
$getParameter = $request->get('getParameter');

You can use parameters like that

<jsp:include page='about.jsp'>
    <jsp:param name="articleId" value=""/>
</jsp:include>

and

in about.jsp you can take the paramter

<%String leftAds = request.getParameter("articleId");%>

String onevalue;   
if(request.getParameterMap().containsKey("one")!=false) 
{
onevalue=request.getParameter("one").toString();
}

I got this working : -

$.get('api.php', 'client=mikescafe', function(data) {
...
});

It sends via get the string ?client=mikescafe then collect this variable in api.php, and use it in your mysql statement.

{{ app.user.username|default('') }}

Just present login username for example, filter function default('') should be nice when user is NOT login by just avoid annoying error message.

I will soon released a new version of my app to support to galaxy ace.

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

I am afraid there is no way to get the query string parameters parsed separately from the post parameters. BTW the fact that such API absent may mean that probably you should check your design. Why are you using query string when sending POST? If you really want to send more data into URL use REST-like convention, e.g. instead of sending

http://mycompany.com/myapp/myservlet?first=11&second=22

say:

http://mycompany.com/myapp/myservlet/11/22

This is from a php script which solves the problem perfectly with every browser I've tested (FF since 3.5, IE8+, Chrome)

header("Content-Disposition: attachment; filename=\"".$fname_local."\"");
header("Content-Type: application/force-download");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($fname));

So as far as I can see, you're doing everything correctly. Have you checked your browser settings?

I just found this post: http://forum.springsource.org/showthread.php?68949-White-spaces-are-required-between-publicId-and-systemId./page2&s=c69fe19798f5a071d22eaf681ca84a56

A couple people here had success by switching the lines around in an XML file.

Spring has MockHttpServletRequest in its spring-test module.

If you are using maven you may need to add the appropriate dependency to your pom.xml. You can find spring-test at mvnrepository.com.

I faced this problem today and resolved it by checking the mapping class. I had a class which had 5 properties to which 5 columns returned from stored procedure were being mapped. Those properties were non-nullable and due to which i was getting the error. I made them nullable and the issue resolved.

    public int? Pause { get; set; }
    public int? Delay { get; set; }
    public int? Transition { get; set; }
    public int? TransitionTime { get; set; }
    public int? TransitionResolution { get; set; }

Added "?" with data type to made them nullable.

Secondly i also added isNull check in the stored procedure as well as follows:

    isnull(co_pivot.Pause, 0) as Pause,
    isnull(co_pivot.Delay, 0) as Delay,
    isnull(co_pivot.Transition, 0) as Transition,
    isnull(co_pivot.TransitionTime, 0) as TransitionTime,
    isnull(co_pivot.TransitionResolution, 0) as TransitionResolution

Hope this helps someone.

I encountered a similar issue, I created a 'foo' folder and created a "class" inside foo, then I get the aforementioned error. One fix is to add "static" as earlier mentioned to the class which will be "public static class LinqHelper".

My assumption is that when you create a class inside the foo folder it regards it as an extension class, hence the following inter alia rule apply to it:

1) Every extension method must be a static method

WORKAROUND If you don't want static. My workaround was to create a class directly under the namespace and then drag it to the "foo" folder.

Looking at the output, it seems that your "temp" is a String array. You need to loop across the array to display each value.

You cannot modify a result from a LDAP query. Your problem is in this line:

seeAlso.add(groupDn);

The seeAlso list is unmodifiable.

In my case the root of the problem was duplicate property name in the client json which only differed by case sensitivity.

    public static void main(String[] args) {

            char c = (char)b;
            if(!Character.isDigit(c))
                isNumber = false;
        }

        return isNumber;
    }

}

First you should probably refactor this a bit so that the DataManager is not created in the doPost code.. you should try Dependency Injection to get an instance. (See the Guice video for a nice intro to DI.). If you're being told to start unit testing everything, then DI is a must-have.

Once your dependencies are injected you can test your class in isolation.

To actually test the servlet, there are other older threads that have discussed this.. try here and here.

from http://www.coderanch.com/t/361868/Servlets/java/request-getParameter-request-getAttribute

A "parameter" is a name/value pair sent from the client to the server - typically, from an HTML form. Parameters can only have String values. Sometimes (e.g. using a GET request) you will see these encoded directly into the URL (after the ?, each in the form name=value, and each pair separated by an &). Other times, they are included in the body of the request, when using methods such as POST.

An "attribute" is a server-local storage mechanism - nothing stored in scoped attribues is ever transmitted outside the server unless you explicitly make that happen. Attributes have String names, but store Object values. Note that attributes are specific to Java (they store Java Objects), while parameters are platform-independent (they are only formatted strings composed of generic bytes).

There are four scopes of attributes in total: "page" (for JSPs and tag files only), "request" (limited to the current client's request, destroyed after request is completed), "session" (stored in the client's session, invalidated after the session is terminated), "application" (exist for all components to access during the entire deployed lifetime of your application).

The bottom line is: use parameters when obtaining data from the client, use scoped attributes when storing objects on the server for use internally by your application only.

The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).

Typical symptoms:

[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100

[root@host /]# netstat -plant | grep 25
tcp        0      0 :::25                       :::*                        LISTEN      1082/exim           

If this happens, make sure that you don't have two entries for localhost in /etc/hosts with different IP addresses, like this (bad) example:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1       localhost localhost.localdomain localhost6 localhost6.localdomain6

To avoid confusion, make sure you only have one entry for localhost, preferably an IPv4 address, like this:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost  localhost.localdomain   localhost4.localdomain4 localhost4
::1       localhost6 localhost6.localdomain6

The request body is available as byte stream by HttpServletRequest#getInputStream():

InputStream body = request.getInputStream();
// ...

Or as character stream by HttpServletRequest#getReader():

Reader body = request.getReader();
// ...

Note that you can read it only once. The client ain't going to resend the same request multiple times. Calling getParameter() and so on will implicitly also read it. If you need to break down parameters later on, you've got to store the body somewhere and process yourself.

In order to be able to expose some configuration parameters for your bundle you should consult the documentation for doing so. It's fairly easy to do :)

Here's the link: How to expose a Semantic Configuration for a Bundle

I faced the issue when i was using ZBar for scanning in tabs. Camera orientation issue. Using below code i was able to resolve issue. This is not the whole code snippet, Please take only help from this.

 public void surfaceChanged(SurfaceHolder holder, int format, int width,
                               int height) {
     if (isPreviewRunning) {
            mCamera.stopPreview();
        }

 setCameraDisplayOrientation(mCamera);

        previewCamera();

    }



 public void previewCamera() {

        try {
            // Hard code camera surface rotation 90 degs to match Activity view
            // in portrait
            mCamera.setPreviewDisplay(mHolder);
            mCamera.setPreviewCallback(previewCallback);
            mCamera.startPreview();
            mCamera.autoFocus(autoFocusCallback);
            isPreviewRunning = true;
        } catch (Exception e) {
            Log.d("DBG", "Error starting camera preview: " + e.getMessage());
        }


    }


public void setCameraDisplayOrientation(android.hardware.Camera camera) {
        Camera.Parameters parameters = camera.getParameters();

        android.hardware.Camera.CameraInfo camInfo =
                new android.hardware.Camera.CameraInfo();
        android.hardware.Camera.getCameraInfo(getBackFacingCameraId(), camInfo);


        Display display = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
        int rotation = display.getRotation();
        int degrees = 0;
        switch (rotation) {
            case Surface.ROTATION_0:
                degrees = 0;
                break;
            case Surface.ROTATION_90:
                degrees = 90;
                break;
            case Surface.ROTATION_180:
                degrees = 180;
                break;
            case Surface.ROTATION_270:
                degrees = 270;
                break;
        }

        int result;
        if (camInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            result = (camInfo.orientation + degrees) % 360;
            result = (360 - result) % 360;  // compensate the mirror
        } else {  // back-facing
            result = (camInfo.orientation - degrees + 360) % 360;
        }
        camera.setDisplayOrientation(result);
    }




    private int getBackFacingCameraId() {
        int cameraId = -1;
        // Search for the front facing camera
        int numberOfCameras = Camera.getNumberOfCameras();
        for (int i = 0; i < numberOfCameras; i++) {
            Camera.CameraInfo info = new Camera.CameraInfo();
            Camera.getCameraInfo(i, info);
            if (info.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {

                cameraId = i;
                break;
            }
        }
        return cameraId;
    }

It says "POST not supported", so the request is not calling your servlet. If I were you, I will issue a GET (e.g. access using a browser) to the exact URL you are issuing your POST request, and see what you get. I bet you'll see something unexpected.

I don't know if I got you right, but, as I understand, you could use an additional hidden field with the value "add tag" and let the button have the desired text.

I had this error plaguing me for the past few hours. Turns out, I had added the custom view lib as a module in Android Studio, but I had neglected to add it as a dependency in app's build.gradle.

dependencies {
    ...
    compile project(':gifview')
}

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

If you simply want to avoid the drawbacks of Java coding in JSP you can do so even with scriplets. Just follow some discipline to have minimal Java in JSP and almost no calculation and logic in the JSP page.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<% // Instantiate a JSP controller
MyController clr = new MyController(request, response);

// Process action, if any
clr.process(request);

// Process page forwarding, if necessary

// Do all variable assignment here
String showMe = clr.getShowMe();%>

<html>
    <head>
    </head>
    <body>
        <form name="frm1">
            <p><%= showMe %>
            <p><% for(String str : clr.listOfStrings()) { %>
            <p><%= str %><% } %>

            // And so on   
        </form>
    </body>
</html>

I simply got this error because my .cpp file was not in the makefile.

In general, if you forget to compile or link to the specific object file containing the definition, you will run into this error.

As per this the default is 2 MB for your <Connector>.

maxPostSize = The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Edit Tomcat's server.xml. In the <Connector> element, add an attribute maxPostSize and set a larger value (in bytes) to increase the limit.

Having said that, if this is the issue, you should have got an exception on the lines of Post data too big in tomcat

For Further Info

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

you can upload file using jsp /servlet.

<form action="UploadFileServlet" method="post">
  <input type="text" name="description" />
  <input type="file" name="file" />
  <input type="submit" />
</form>

on the other hand server side. use following code.

     package com.abc..servlet;

import java.io.File;
---------

/**

Introduction

You should use doGet() when you want to intercept on HTTP GET requests. You should use doPost() when you want to intercept on HTTP POST requests. That's all. Do not port the one to the other or vice versa (such as in Netbeans' unfortunate auto-generated processRequest() method). This makes no utter sense.

GET

Usually, HTTP GET requests are idempotent. I.e. you get exactly the same result everytime you execute the request (leaving authorization/authentication and the time-sensitive nature of the page —search results, last news, etc— outside consideration). We can talk about a bookmarkable request. Clicking a link, clicking a bookmark, entering raw URL in browser address bar, etcetera will all fire a HTTP GET request. If a Servlet is listening on the URL in question, then its doGet() method will be called. It's usually used to preprocess a request. I.e. doing some business stuff before presenting the HTML output from a JSP, such as gathering data for display in a table.

@WebServlet("/products")
public class ProductsServlet extends HttpServlet {

    @EJB
    private ProductService productService;

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        List<Product> products = productService.list();
        request.setAttribute("products", products); // Will be available as ${products} in JSP
        request.getRequestDispatcher("/WEB-INF/products.jsp").forward(request, response);
    }

}

Note that the JSP file is explicitly placed in /WEB-INF folder in order to prevent endusers being able to access it directly without invoking the preprocessing servlet (and thus end up getting confused by seeing an empty table).

<table>
    <c:forEach items="${products}" var="product">
        <tr>
            <td>${product.name}</td>
            <td><a href="product?id=${product.id}">detail</a></td>
        </tr>
    </c:forEach>
</table>

Also view/edit detail links as shown in last column above are usually idempotent.

@WebServlet("/product")
public class ProductServlet extends HttpServlet {

    @EJB
    private ProductService productService;

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        Product product = productService.find(request.getParameter("id"));
        request.setAttribute("product", product); // Will be available as ${product} in JSP
        request.getRequestDispatcher("/WEB-INF/product.jsp").forward(request, response);
    }

}

<dl>
    <dt>ID</dt>
    <dd>${product.id}</dd>
    <dt>Name</dt>
    <dd>${product.name}</dd>
    <dt>Description</dt>
    <dd>${product.description}</dd>
    <dt>Price</dt>
    <dd>${product.price}</dd>
    <dt>Image</dt>
    <dd><img src="productImage?id=${product.id}" /></dd>
</dl>

POST

HTTP POST requests are not idempotent. If the enduser has submitted a POST form on an URL beforehand, which hasn't performed a redirect, then the URL is not necessarily bookmarkable. The submitted form data is not reflected in the URL. Copypasting the URL into a new browser window/tab may not necessarily yield exactly the same result as after the form submit. Such an URL is then not bookmarkable. If a Servlet is listening on the URL in question, then its doPost() will be called. It's usually used to postprocess a request. I.e. gathering data from a submitted HTML form and doing some business stuff with it (conversion, validation, saving in DB, etcetera). Finally usually the result is presented as HTML from the forwarded JSP page.

<form action="login" method="post">
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="submit" value="login">
    <span class="error">${error}</span>
</form>

...which can be used in combination with this piece of Servlet:

@WebServlet("/login")
public class LoginServlet extends HttpServlet {

    @EJB
    private UserService userService;

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String username = request.getParameter("username");
        String password = request.getParameter("password");
        User user = userService.find(username, password);

        if (user != null) {
            request.getSession().setAttribute("user", user);
            response.sendRedirect("home");
        }
        else {
            request.setAttribute("error", "Unknown user, please try again");
            request.getRequestDispatcher("/login.jsp").forward(request, response);
        }
    }

}

You see, if the User is found in DB (i.e. username and password are valid), then the User will be put in session scope (i.e. "logged in") and the servlet will redirect to some main page (this example goes to http://example.com/contextname/home), else it will set an error message and forward the request back to the same JSP page so that the message get displayed by ${error}.

You can if necessary also "hide" the login.jsp in /WEB-INF/login.jsp so that the users can only access it by the servlet. This keeps the URL clean http://example.com/contextname/login. All you need to do is to add a doGet() to the servlet like this:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    request.getRequestDispatcher("/WEB-INF/login.jsp").forward(request, response);
}

(and update the same line in doPost() accordingly)

That said, I am not sure if it is just playing around and shooting in the dark, but the code which you posted doesn't look good (such as using compareTo() instead of equals() and digging in the parameternames instead of just using getParameter() and the id and password seems to be declared as servlet instance variables — which is NOT threadsafe). So I would strongly recommend to learn a bit more about basic Java SE API using the Oracle tutorials (check the chapter "Trails Covering the Basics") and how to use JSP/Servlets the right way using those tutorials.

• Our servlets wiki page
• Java EE web development, where do I start and what skills do I need?
• Servlet returns "HTTP Status 404 The requested resource (/servlet) is not available"
• Show JDBC ResultSet in HTML in JSP page using MVC and DAO pattern

Update: as per the update of your question (which is pretty major, you should not remove parts of your original question, this would make the answers worthless .. rather add the information in a new block) , it turns out that you're unnecessarily setting form's encoding type to multipart/form-data. This will send the request parameters in a different composition than the (default) application/x-www-form-urlencoded which sends the request parameters as a query string (e.g. name1=value1&name2=value2&name3=value3). You only need multipart/form-data whenever you have a <input type="file"> element in the form to upload files which may be non-character data (binary data). This is not the case in your case, so just remove it and it will work as expected. If you ever need to upload files, then you'll have to set the encoding type so and parse the request body yourself. Usually you use the Apache Commons FileUpload there for, but if you're already on fresh new Servlet 3.0 API, then you can just use builtin facilities starting with HttpServletRequest#getPart(). See also this answer for a concrete example: How to upload files to server using JSP/Servlet?

I'am posting this answer because many visitors enter here from google for this problem.

string result = this.GetType().GetMethod("Print").Invoke(this, new object[]{"firstParam", 157, "third_Parammmm" } );

when external .dll -instead of this.GetType(), you might use typeof(YourClass).

even adding a return statement brings up this exception, for which only solution is this code:

if(!response.isCommitted())
// Place another redirection

I have methods to achieve this:

1):

public static String getQueryString(String url, String tag) {
    String[] params = url.split("&");
    Map<String, String> map = new HashMap<String, String>();
    for (String param : params) {
        String name = param.split("=")[0];
        String value = param.split("=")[1];
        map.put(name, value);
    }

    Set<String> keys = map.keySet();
    for (String key : keys) {
        if(key.equals(tag)){
         return map.get(key);
        }
        System.out.println("Name=" + key);
        System.out.println("Value=" + map.get(key));
    }
    return "";
}

2) and the easiest way to do this Using Uri class:

public static String getQueryString(String url, String tag) {
    try {
        Uri uri=Uri.parse(url);
        return uri.getQueryParameter(tag);
    }catch(Exception e){
        Log.e(TAG,"getQueryString() " + e.getMessage());
    }
    return "";
}

and this is an example of how to use either of two methods:

String url = "http://www.jorgesys.com/advertisements/publicidadmobile.htm?position=x46&site=reform&awidth=800&aheight=120";      
String tagValue = getQueryString(url,"awidth");

the value of tagValue is 800

Java's URI Class can help you out of this:

public static String getCurrentUrl(HttpServletRequest request){
    URL url = new URL(request.getRequestURL().toString());
    String host  = url.getHost();
    String userInfo = url.getUserInfo();
    String scheme = url.getProtocol();
    String port = url.getPort();
    String path = request.getAttribute("javax.servlet.forward.request_uri");
    String query = request.getAttribute("javax.servlet.forward.query_string");

    URI uri = new URI(scheme,userInfo,host,port,path,query,null)
    return uri.toString();
}

Try request.setAttribute("param",value);. It worked fine for me.

Please find this code sample:

private void sanitizePrice(ServletRequest request){
        if(request.getParameterValues ("price") !=  null){
            String price[] = request.getParameterValues ("price");

            for(int i=0;i<price.length;i++){
                price[i] = price[i].replaceAll("[^\\dA-Za-z0-9- ]", "").trim();
                System.out.println(price[i]);
            }
            request.setAttribute("price", price);
            //request.getParameter("numOfBooks").re
        }
    }

I worked on this same issue and I am sure I have found out the exact reason for it.

Neither BindingResult nor plain target object for bean name 'command' available as request attribute

If your successView property value (name of jsp page) is the same as your input page name, then second value of ModelAndView constructor must be match with the commandName of the input page.

E.g.

Sorry, but why not use the following construction:

request.getParameterMap().put(parameterName, new String[] {parameterValue});

You can use link-rewriting to append a unique identifier to all your URLs when starting at a single page (e.g. index.html/jsp/whatever). The browser will use the same cookies for all your tabs so everything you put in cookies will not be unique.

If you don't mind fiddling with JS, I wrote a small jQuery plugin that helps you do it. With it you don't need to worry about vendor prefixes.

 $.fn.magicSelectBox = function() {
  var $e = this;

  $e.each(function() {
    var $select = $(this);

    var $magicbox = $('<div></div>').attr('class', $select.attr('class')).attr('style', $select.attr('style')).addClass('magicbox');
    var $innermagicbox = $('<div></div>').css({
      position: 'relative',
      height: '100%'
    });
    var $text = $('<span></span>').css({
      position: 'absolute'
    }).text($select.find("option:selected").text());

    $select.attr('class', null).css({
      width: '100%',
      height: '100%',
      opacity: 0,
      position: 'absolute'
    }).on('change', function() {
      $text.text($select.find("option:selected").text());
    });

    $select.parent().append($magicbox);
    $innermagicbox.append($text, $select);
    $magicbox.append($innermagicbox);
  });

  return $e;
};

Fiddle here: JS Fiddle

The condition is that you have to style the select from scratch (this means setting the background and border), but you probably want to do this anyway.

Also since the function substitutes the original select with a div, you will lose any styling done directly on the select selector in your CSS. So give the select element a class and style the class.

Supports most modern browsers, if you want to target older browsers, you can try an older version of jQuery, but perhaps have to replace on() with bind() in the function (not tested)

I can guarantee you that bash alone won't be any faster than sed for this task. Starting up external processes in bash is a generally bad idea but only if you do it a lot.

So, if you're starting a sed process for each line of your input, I'd be concerned. But you're not. You only need to start one sed which will do all the work for you.

You may however find that the following sed will be a bit faster than your version:

(whatever) | sed 's/...$//'

All this does is remove the last three characters on each line, rather than substituting the whole line with a shorter version of itself. Now maybe more modern RE engines can optimise your command but why take the risk.

To be honest, about the only way I can think of that would be faster would be to hand-craft your own C-based filter program. And the only reason that may be faster than sed is because you can take advantage of the extra knowledge you have on your processing needs (sed has to allow for generalised procession so may be slower because of that).

Don't forget the optimisation mantra: "Measure, don't guess!"

If you really want to do this one line at a time in bash (and I still maintain that it's a bad idea), you can use:

pax> line=123456789abc
pax> line2=${line%%???}
pax> echo ${line2}
123456789
pax> _

You may also want to investigate whether you actually need a speed improvement. If you process the lines as one big chunk, you'll see that sed is plenty fast. Type in the following:

#!/usr/bin/bash

echo This is a pretty chunky line with three bad characters at the end.XXX >qq1
for i in 4 16 64 256 1024 4096 16384 65536 ; do
    cat qq1 qq1 >qq2
    cat qq2 qq2 >qq1
done

head -20000l qq1 >qq2
wc -l qq2

date
time sed 's/...$//' qq2 >qq1
date
head -3l qq1

and run it. Here's the output on my (not very fast at all) R40 laptop:

pax> ./chk.sh
20000 qq2

This is a pretty chunky line with three bad characters at the end.

That's 20,000 lines in under a second, pretty good for something that's only done every hour.

You simply need to enclose your SELECT statements in parentheses to indicate that they are subqueries:

SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);

Alternatively, you can use MySQL's SELECT ... INTO syntax. One advantage of this approach is that both cityLat and cityLng can be assigned from a single table-access:

SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;

However, the entire procedure can be replaced with a single self-joined SELECT statement:

SELECT   b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM     cities AS a, cities AS b
WHERE    a.id = cityID
ORDER BY dist
LIMIT    10;

Console.WriteLine(dt2 != null ? dt2.Value.ToString("yyyy-MM-dd hh:mm:ss") : "n/a"); 

EDIT: As stated in other comments, check that there is a non-null value.

Update: as recommended in the comments, extension method:

public static string ToString(this DateTime? dt, string format)
    => dt == null ? "n/a" : ((DateTime)dt).ToString(format);

And starting in C# 6, you can use the null-conditional operator to simplify the code even more. The expression below will return null if the DateTime? is null.

dt2?.ToString("yyyy-MM-dd hh:mm:ss")

Use document.querySelectorAll() and Loops and iteration

function sibblingOf(children,targetChild){_x000D_
  var children = document.querySelectorAll(children);_x000D_
  for(var i=0; i< children.length; i++){_x000D_
    children[i].addEventListener("click", function(){_x000D_
      for(var y=0; y<children.length;y++){children[y].classList.remove("target")}_x000D_
      this.classList.add("target")_x000D_
    }, false)_x000D_
  }_x000D_
}_x000D_
_x000D_
sibblingOf("#outer >div","#inner2");

#outer >div:not(.target){color:red}

<div id="outer">_x000D_
      <div id="inner1">Div 1 </div>_x000D_
      <div id="inner2">Div 2 </div>_x000D_
      <div id="inner3">Div 3 </div>_x000D_
      <div id="inner4">Div 4 </div>_x000D_
 </div>

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

You can also use regions. See https://www.myandroidsolutions.com/2014/06/21/android-studio-intellij-idea-code-regions/

Select a block of code, then press Code > Surround With... (Ctrl + Alt + T) and select "region...endregion Comments" (2).

From the menu bar: Project -> Properties -> Java Compiler

Enable project specific settings (checked) Uncheck "use Compliance from execution environment '.... Select the desired "compiler compliance level"

That will allow you to compile "1.5" code using a "1.6" JDK.

If you want to acutally use a 1.5 JDK to produce "1.5" compliant code, then install a suitable 1.5 JDK and tell eclipse where it is installed via:

Window -> preferences -> Installed JREs

And then go back to your project

Project -> properties -> Java Build Path -> libraries

remove the 1.6 system libaries, and: add library... -> JRE System LIbrary -> Alternate JRE -> The JRE you want.

Verify that the correct JRE is on the project's build path, save everything, and enjoy!

Another important consideration: The Elvis Operator breaks the Zend Opcache tokenization process. I found this the hard way! While this may have been fixed in later versions, I can confirm this problem exists in PHP 5.5.38 (with in-built Zend Opcache v7.0.6-dev).

If you find that some of your files 'refuse' to be cached in Zend Opcache, this may be one of the reasons... Hope this helps!

[ ]{2,}

SPACE (2 or more)

You could also check that before and after those spaces words follow. (not other whitespace like tabs or new lines)

\w[ ]{2,}\w

the same, but you can also pick (capture) only the spaces for tasks like replacement

\w([ ]{2,})\w

or see that before and after spaces there is anything, not only word characters (except whitespace)

[^\s]([ ]{2,})[^\s]

In Visual Studio 2012 I was able to achieve the same result easier than in the accepted solution.

I changed the option in menu Tools ? Options ? Projects and Solutions ? Build and Run ? *MSBuild project build output verbosity" from Minimal to Diagnostic.

Then in the build output I found the same lines by searching for "not up to date":

Project 'blabla' is not up to date. Project item 'c:\foo\bar.xml' has 'Copy to Output Directory' attribute set to 'Copy always'.

In VS Express 2012 I couldn't find System.Web.Mvc in the "assemblies" tab, but after a bit of searching I found out that I need to look into "assemblies\extensions" tab rather than the default "assemblies\framework" tab.

Not sure about older versions, but in 2016.2 removing the .key file(s) didn't work for me.

If you only need to know for your own information, just look in /usr/include/boost/version.hpp (Ubuntu 13.10) and read the information directly

It is SUBSTITUTE(B1," ",""), not REPLACE(xx;xx;xx).

Bootstrap has column offsets, so if you want columns with equal width without specifying size use this.

<div class="row">
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="col">col</div>
</div>

I just figured out a way to fix the alignment issue. Changing the width of div containing the static header will fix its alignment. The optimal width I found is 98%. Please refer to the code.

The auto generated div:

<div class="dataTables_scrollHead" style="overflow: hidden; position: relative; border: 0px none; width: 100%;">

Width here is 100%, change it to 98% on initializing and reloading the data table.

jQuery('#dashboard').dataTable({
    "sEcho": "1",

    "aaSorting": [[aasortvalue, 'desc']],
    "bServerSide": true,
    "sAjaxSource": "NF.do?method=loadData&Table=dashboardReport",
    "bProcessing": true,
    "sPaginationType": "full_numbers",
    "sDom": "lrtip", // Add 'f' to add back in filtering
    "bJQueryUI": false,
    "sScrollX": "100%",
    "sScrollY": "450px",
    "iDisplayLength": '<%=recordCount%>',
    "bScrollCollapse": true,
    "bScrollAutoCss": true,
    "fnInitComplete": function () {
        jQuery('.dataTables_scrollHead').css('width', '98%'); //changing the width
    },
    "fnDrawCallback": function () {
        jQuery('.dataTables_scrollHead').css('width', '98%');//changing the width
    }
});

ES6: In HTML, include the main JavaScript file using attribute type="module" (browser support):

<script type="module" src="script.js"></script>

And in the script.js file, include another file like this:

import { hello } from './module.js';
...
// alert(hello());

Inside the included file (module.js), you must export the function/class that you will import:

export function hello() {
    return "Hello World";
}

A working example is here. More information is here.

Basically you need to do two loops here. The one you are doing already is iterating each element in the 0th array element.

You have programs: [ {...}, {...} ] so programs[0] is { "name":"zonealarm", "price":"500" } So your loop is just going over that.

You could do an outer loop over the array

$.each(data.programs, function(index) {

    // then loop over the object elements
    $.each(data.programs[index], function(key, value) {
        console.log(key + ": " + value);
    }

}

Many good suggestions above.

Also if you are trying to build in x86 Win32:

Make sure that any libraries you link to in Program Files(x86) are actually x86 libraries because they are not necessarily...

For example a lib file I linked to in C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\SDK threw that error, eventually I found an x86 version of it in C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x86 and everything worked fine.

Other answers already show that you can use split() to get the values into a list. If you were asking about Python's arrays, here is one solution:

import array
s = '42 0'
a = array.array('i')
for n in s.split():
    a.append(int(n))

Edit: A more concise solution:

import array
s = '42 0'
a = array.array('i', (int(t) for t in s.split()))

If I understand clearly, you want to do this programatically. Then, you could use the onTouchEvent method of View, and create a MotionEvent with the coordinates you need.

Please set this in root vc:

-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:YES];
    self.navigationController.interactivePopGestureRecognizer.enabled = NO;

}

-(void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:YES];
    self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}

What exactly do you want to know? ActiveRecord has methods that serialize records into JSON. For instance, open up your rails console and enter ModelName.all.to_json and you will see JSON output. render :json essentially calls to_json and returns the result to the browser with the correct headers. This is useful for AJAX calls in JavaScript where you want to return JavaScript objects to use. Additionally, you can use the callback option to specify the name of the callback you would like to call via JSONP.

For instance, lets say we have a User model that looks like this: {name: 'Max', email:' [email protected]'}

We also have a controller that looks like this:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user
    end
end

Now, if we do an AJAX call using jQuery like this:

$.ajax({
    type: "GET",
    url: "/users/5",
    dataType: "json",
    success: function(data){
        alert(data.name) // Will alert Max
    }        
});

As you can see, we managed to get the User with id 5 from our rails app and use it in our JavaScript code because it was returned as a JSON object. The callback option just calls a JavaScript function of the named passed with the JSON object as the first and only argument.

To give an example of the callback option, take a look at the following:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user, callback: "testFunction"
    end
end

Now we can crate a JSONP request as follows:

function testFunction(data) {
    alert(data.name); // Will alert Max
};

var script = document.createElement("script");
script.src = "/users/5";

document.getElementsByTagName("head")[0].appendChild(script);

The motivation for using such a callback is typically to circumvent the browser protections that limit cross origin resource sharing (CORS). JSONP isn't used that much anymore, however, because other techniques exist for circumventing CORS that are safer and easier.

If you are having trouble tracing the definitions, you can use the preprocessed output of the compiler which will tell you all you need to know. E.g.

$ cat test.c
#include <stdio.h>
$ cc -E test.c | grep off_t
typedef long int __off_t;
typedef __off64_t __loff_t;
  __off_t __pos;
  __off_t _old_offset;
typedef __off_t off_t;
extern int fseeko (FILE *__stream, __off_t __off, int __whence);
extern __off_t ftello (FILE *__stream) ;

If you look at the complete output you can even see the exact header file location and line number where it was defined:

# 132 "/usr/include/bits/types.h" 2 3 4


typedef unsigned long int __dev_t;
typedef unsigned int __uid_t;
typedef unsigned int __gid_t;
typedef unsigned long int __ino_t;
typedef unsigned long int __ino64_t;
typedef unsigned int __mode_t;
typedef unsigned long int __nlink_t;
typedef long int __off_t;
typedef long int __off64_t;

...

# 91 "/usr/include/stdio.h" 3 4
typedef __off_t off_t;

The KeyDown event only triggered at the standard TextBox or MaskedTextBox by "normal" input keys, not ENTER or TAB and so on.

One can get special keys like ENTER by overriding the IsInputKey method:

public class CustomTextBox : System.Windows.Forms.TextBox
{
    protected override bool IsInputKey(Keys keyData)
    {
        if (keyData == Keys.Return)
            return true;
        return base.IsInputKey(keyData);
    }
}

Then one can use the KeyDown event in the following way:

CustomTextBox ctb = new CustomTextBox();
ctb.KeyDown += new KeyEventHandler(tb_KeyDown);

private void tb_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
          //Enter key is down

          //Capture the text
          if (sender is TextBox)
          {
              TextBox txb = (TextBox)sender;
              MessageBox.Show(txb.Text);
          }
    }
}

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

Anyone gets this error when 'npm install' is trying to fetch a package from HTTPS server with a self-signed or invalid certificate.

Quick and insecure solution:

npm config set strict-ssl false

Why this solution is insecure? The above command tells npm to connect and fetch module from server even server do not have valid certificate and server identity is not verified. So if there is a proxy server between npm client and actual server, it provided man in middle attack opportunity to an intruder.

Secure solution:

If any module in your package.json is hosted on a server with self-signed CA certificate then npm is unable to identify that server with an available system CA certificates. So you need to provide CA certificate for server validation with the explicit configuration in .npmrc. In .npmrc you need to provide cafile, please refer more detail about cafile configuration here

cafile=./ca-certs.pem

In ca-certs file, you can add any number of CA certificates(public) that you required to identify servers. The certificate should be in “Base-64 encoded X.509 (.CER)(PEM)” format.

For example,

# cat ca-certs.pem 
DigiCert Global Root CA
=======================
-----BEGIN CERTIFICATE-----
CAUw7C29C79Fv1C5qfPrmAE.....
-----END CERTIFICATE-----

VeriSign Class 3 Public Primary Certification Authority - G5
========================================
-----BEGIN CERTIFICATE-----
MIIE0zCCA7ugAwIBAgIQ......
-----END CERTIFICATE-----

Note: once you provide cafile configuration in .npmrc, npm try to identify all server using CA certificate(s) provided in cafile only, it won't check system CA certificate bundles then. If someone wants all well-known public CA authority certificat bundle then can get from here.

One other situation when you get this error:

If you have mentioned Git URL as a dependency in package.json and git is on invalid/self-signed certificate then also npm throws a similar error. You can fix it with following configuration for git client

git config --global http.sslVerify false 

You can return "ResponseEntity" object. Using "ResponseEntity" object is very convenient both at the time of constructing the response object (that contains Response Body and HTTP Status Code) and at the time of getting information out of the response object.

Methods like getHeaders(), getBody(), getContentType(), getStatusCode() etc makes the work of reading the ResponseEntity object very easy.

You should be using ResponseEntity object with a http status code of 204(No Content), which is specifically to specify that the request has been processed properly and the response body is intentionally blank. Using appropriate Status Codes to convey the right information is very important, especially if you are making an API that is going to be used by multiple client applications.

old question, but posting this for fellow googlers:

Spin.js DOES WORK for this use case: http://fgnass.github.com/spin.js/

Given a unix timestamp (seconds since epoch) of 1494500000, do:

find . -type f -newermt "$(date '+%Y-%m-%d %H:%M:%S' -d @1494500000)"

To grep those files for "foo":

find . -type f -newermt "$(date '+%Y-%m-%d %H:%M:%S' -d @1494500000)" -exec grep -H 'foo' '{}' \;

I recommend using https://www.npmjs.com/package/express-es6-template-engine - extremely lightwave and blazingly fast template engine. The name is a bit misleading as it can work without expressjs too.

The basics required to integrate express-es6-template-engine in your app are pretty simple and quite straight forward to implement:

const express = require('express'),_x000D_
  es6Renderer = require('express-es6-template-engine'),_x000D_
  app = express();_x000D_
  _x000D_
app.engine('html', es6Renderer);_x000D_

Take a look at HTMLSelectElement.selectedOptions.

HTML

<select name="north-america" multiple>
  <option valud="ca" selected>Canada</a>
  <option value="mx" selected>Mexico</a>
  <option value="us">USA</a>
</select>

JavaScript

var elem = document.querySelector("select");

console.log(elem.selectedOptions);
//=> HTMLCollection [<option value="ca">Canada</option>, <option value="mx">Mexico</option>]

This would also work on non-multiple <select> elements

Warning: Support for this selectedOptions seems pretty unknown at this point

Sometime we dont get Java Build Path by directly right click on project. then go to properties....

Then Click on java build path

Click on tab add external jars and give path of your computer file where u have stored jars.

I encountered the same error while using SpringBoot 2.1.4, along with Spring Security 5 (I believe). After one day of trying everything that Google had to offer, I discovered the cause of error in my case. I had a setup of micro-services, with the Auth server being different from the Resource Server. I had the following lines in my application.yml which prevented 'auto-configuration' despite of having included dependencies spring-boot-starter-security, spring-security-oauth2 and spring-security-jwt. I had included the following in the properties (during development) which caused the error.

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Commenting it out solved it for me.

#spring:
#  autoconfigure:
#    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Hope, it helps someone.

After lots of searching This code work for me:

Check the permission already has: Check WRITE_EXTERNAL_STORAGE permission Allowed or not?

if(isReadStorageAllowed()){
            //If permission is already having then showing the toast
            //Toast.makeText(SplashActivity.this,"You already have the permission",Toast.LENGTH_LONG).show();
            //Existing the method with return
            return;
        }else{
            requestStoragePermission();
        }



private boolean isReadStorageAllowed() {
    //Getting the permission status
    int result = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);

    //If permission is granted returning true
    if (result == PackageManager.PERMISSION_GRANTED)
        return true;

    //If permission is not granted returning false
    return false;
}

//Requesting permission
private void requestStoragePermission(){

    if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)){
        //If the user has denied the permission previously your code will come to this block
        //Here you can explain why you need this permission
        //Explain here why you need this permission
    }

    //And finally ask for the permission
    ActivityCompat.requestPermissions(this,new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE},REQUEST_WRITE_STORAGE);
}

Implement Override onRequestPermissionsResult method for checking is the user allow or denie

 @Override
 public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    //Checking the request code of our request
    if(requestCode == REQUEST_WRITE_STORAGE){

        //If permission is granted
        if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){

            //Displaying a toast
            Toast.makeText(this,"Permission granted now you can read the storage",Toast.LENGTH_LONG).show();

        }else{
            //Displaying another toast if permission is not granted
            Toast.makeText(this,"Oops you just denied the permission",Toast.LENGTH_LONG).show();
        }
    }

This may not be the answer you are looking for, but may help others whose jquery is not working properly, or working sometimes and not at other times.

This could be because your jquery has not yet loaded and you have started to interact with the page. Either put jquery on top in head (probably not a very great idea) or use a loader or spinner to stop the user from interacting with the page until the entire jquery has loaded.

Use following code

List data = getJdbcTemplate().queryForList(query,String.class)

<?php $sql = "SELECT * FROM guest_book";
                            $res = mysql_query($sql);
                            if (mysql_num_rows($res)) {
                            $query = mysql_query("SELECT * FROM guest_book ORDER BY id");
                            $i=1;
                            while($row = mysql_fetch_assoc($query)){
                            ?>


<input type="checkbox" name="checkboxstatus[<?php echo $i; ?>]" value="<?php echo $row['id']; ?>"  />

<?php $i++; }} ?>


<input type="submit" value="Delete" name="Delete" />

if($_REQUEST['Delete'] != '')
{
    if(!empty($_REQUEST['checkboxstatus'])) {
        $checked_values = $_REQUEST['checkboxstatus'];
        foreach($checked_values as $val) {
            $sqldel = "DELETE from guest_book WHERE id = '$val'";
           mysql_query($sqldel);

        }
    }
} 

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

In the jar file you could just add this to your manifest.mft

Main-Class : A

The jar file would then be executable and would call the correct main.

On how to do this in Netbeans you can look at this: Producing executable jar in NetBeans

In java spark dataset it can be used as

Dataset userfilter = user.filter(col("gender").isin("male","female"));

try this

session_start();
$name = $_GET["username"];
$sql = "SELECT 'id' FROM Users WHERE username='$name' LIMIT 1 ";
$result = mysql_query($sql) or die(mysql_error());
if($row = mysql_fetch_assoc($result))
{
      $_SESSION['myid'] = $row['id'];
}

The highly regarded Joda Time library is also worth a look. This is basis for the new date and time api that is pencilled in for Java 7. The design is neat, intuitive, well documented and avoids a lot of the clumsiness of the original java.util.Date / java.util.Calendar classes.

Joda's DateFormatter can parse a String to a Joda DateTime.

So i had a adifferent case where i needed to assign values before running a session, So this was the easiest way to do that:

other_variable = tf.get_variable("other_variable", dtype=tf.int32,
  initializer=tf.constant([23, 42]))

here i'm creating a variable as well as assigning it values at the same time

If you have an object and wish to become JObject you can use:

JObject o = (JObject)JToken.FromObject(miObjetoEspecial);

like this :

Pocion pocionDeVida = new Pocion{
tipo = "vida",
duracion = 32,
};

JObject o = (JObject)JToken.FromObject(pocionDeVida);
Console.WriteLine(o.ToString());
// {"tipo": "vida", "duracion": 32,}

it's very simple getting a name:

$('[name=elementname]');

You have one DateFormat, but you need two: one for the input, and another for the output.

You've got one for the output, but I don't see anything that would match your input. When you give the input string to the output format, it's no surprise that you see that exception.

DateFormat inputDateFormat = new SimpleDateFormat("yyyy-MM-ddhh:mm:ss.SSS-Z");

So there might be a few things wrong here.

First start by reading how to use XMLHttpRequest.open() because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send(). Here's an example from MDN:

var oXHR = new XMLHttpRequest();

oXHR.open("GET", "http://www.mozilla.org/", true);

oXHR.onreadystatechange = function (oEvent) {
    if (oXHR.readyState === 4) {
        if (oXHR.status === 200) {
          console.log(oXHR.responseText)
        } else {
           console.log("Error", oXHR.statusText);
        }
    }
};

oXHR.send(null);

Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml file.

You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:

var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false); 
request.send(null);

if (request.status == 0)
    console.log(request.responseText);

Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.

Com'on, no mention of Fiddler? Where's the love :)

Fiddler is a very popular HTTP debugger aimed at developers and not network admins (i.e. Wireshark).

Setting it up for iOS is fairly simple process. It can decrypt HTTPS traffic too!

Our mobile team is finally reliefed after QA department started using Fiddler to troubleshoot issues. Before fiddler, people fiddled around to know who to blame, mobile team or APIs team, but not anymore.

Requests does not currently support asyncio and there are no plans to provide such support. It's likely that you could implement a custom "Transport Adapter" (as discussed here) that knows how to use asyncio.

If I find myself with some time it's something I might actually look into, but I can't promise anything.

Simple solution

<?php
   $x = 1;
     for($x = 1; $x < 8; $x++) {
        $x = $x + 1;
       echo $x;
     };    
?>

After all else failed...

My solution was to change the layout file from

= stylesheet_link_tag "reset-min", 'application'

to

= stylesheet_link_tag 'application'

And it worked! (You can put the reset file inside the manifest.)

Try this:

Use back-ticks for NAME

CREATE TABLE `teachers` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `addr` varchar(255) NOT NULL,
  `phone` int(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

  z-index: 1001;
}

fixed

Use this script instead:

@taskkill/f /im test.exe >nul 2>&1
@pause

What the 2>&1 part actually does, is that it redirects the stderr output to stdout. I will explain it better below:

@taskkill/f /im test.exe >nul 2>&1

Kill the task "test.exe". Redirect stderr to stdout. Then, redirect stdout to nul.

@pause

Show the pause message Press any key to continue . . . until someone presses a key.

NOTE: The @ symbol is hiding the prompt for each command. You can save up to 8 bytes this way.

The shortest version of your script could be:
@taskkill/f /im test.exe >nul 2>&1&pause
The & character is used for redirection the first time, and for separating the commands the second time.
An @ character is not needed twice in a line. This code is just 40 bytes, despite the one you've posted being 49 bytes! I actually saved 9 bytes. For a cleaner code look above.

The info inside the <script> tag is then processed inside it to access other parts. If you want to change the text inside another paragraph, then first give the paragraph an id, then set a variable to it using getElementById([id]) to access it ([id] means the id you gave the paragraph). Next, use the innerHTML built-in variable with whatever your variable was called and a '.' (dot) to show that it is based on the paragraph. You can set it to whatever you want, but be aware that to set a paragraph to a tag (<...>), then you have to still put it in speech marks.

Example:

<!DOCTYPE html>_x000D_
<html>_x000D_
    <body>_x000D_
        <!--\|/id here-->_x000D_
        <p id="myText"></p>_x000D_
        <p id="myTextTag"></p>_x000D_
        <script>_x000D_
            <!--Here we retrieve the text and show what we want to write..._x000D_
            var text = document.getElementById("myText");_x000D_
            var tag = document.getElementById("myTextTag");_x000D_
            var toWrite = "Hello"_x000D_
            var toWriteTag = "<a href='https://stackoverflow.com'>Stack Overflow</a>"_x000D_
            <!--...and here we are actually affecting the text.-->_x000D_
            text.innerHTML = toWrite_x000D_
            tag.innerHTML = toWriteTag_x000D_
        </script>_x000D_
    <body>_x000D_
<html>

Use Shift + Insert like in linux bash

Use --build-arg with each argument.

If you are passing two argument then add --build-arg with each argument like:

--build-arg number_of_shards=5 \
--build-arg number_of_replicas=2 \
--no-cache .

You should use the StringBuilder class.

StringBuilder stringBuilder = new StringBuilder();

stringBuilder.append("Some text");
stringBuilder.append("Some text");
stringBuilder.append("Some text");

String finalString = stringBuilder.toString();

In addition, please visit:

• "How Java optimize the code with StringBuilder?"
• "StringBuilder vs String concatenation in toString() in Java"

Answer is to escape the dash!

select to_timestamp(cast(epoch_ms/1000 as bigint))::date

worked for me

If you have specific chars should be:

Collection<Character> specificChars = Arrays.asList('A', 'D', 'E');  // more chars
char symbol = 'Y';
System.out.println(specificChars.contains(symbol));   // false
symbol = 'A';
System.out.println(specificChars.contains(symbol));   // true           

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You can read the full documentation here.

If these strings are currently in the db, you can skip php by using mysql's STR_TO_DATE() function.

I assume the strings use a format like month/day/year where month and day are always 2 digits, and year is 4 digits.

UPDATE some_table
   SET new_column = STR_TO_DATE(old_column, '%m/%d/%Y')

You can support other date formats by using other format specifiers.

You need to distinguish between two separate concepts: function definition and symbol declaration. "extern" is a linkage modifier, a hint to the compiler about where the symbol referred to afterwards is defined (the hint is, "not here").

If I write

extern int i;

in file scope (outside a function block) in a C file, then you're saying "the variable may be defined elsewhere".

extern int f() {return 0;}

is both a declaration of the function f and a definition of the function f. The definition in this case over-rides the extern.

extern int f();
int f() {return 0;}

is first a declaration, followed by the definition.

Use of extern is wrong if you want to declare and simultaneously define a file scope variable. For example,

extern int i = 4;

will give an error or warning, depending on the compiler.

Usage of extern is useful if you explicitly want to avoid definition of a variable.

Let me explain:

Let's say the file a.c contains:

#include "a.h"

int i = 2;

int f() { i++; return i;}

The file a.h includes:

extern int i;
int f(void);

and the file b.c contains:

#include <stdio.h>
#include "a.h"

int main(void){
    printf("%d\n", f());
    return 0;
}

The extern in the header is useful, because it tells the compiler during the link phase, "this is a declaration, and not a definition". If I remove the line in a.c which defines i, allocates space for it and assigns a value to it, the program should fail to compile with an undefined reference. This tells the developer that he has referred to a variable, but hasn't yet defined it. If on the other hand, I omit the "extern" keyword, and remove the int i = 2 line, the program still compiles - i will be defined with a default value of 0.

File scope variables are implicitly defined with a default value of 0 or NULL if you do not explicitly assign a value to them - unlike block-scope variables that you declare at the top of a function. The extern keyword avoids this implicit definition, and thus helps avoid mistakes.

For functions, in function declarations, the keyword is indeed redundant. Function declarations do not have an implicit definition.

Try running the entire script through jslint. This may help point you at the cause of the error.

Edit Ok, it's not quite the syntax of the script that's the problem. At least not in a way that jslint can detect.

Having played with your live code at http://ft2.hostei.com/ft.v1/, it looks like there are syntax errors in the generated code that your script puts into an onclick attribute in the DOM. Most browsers don't do a very good job of reporting errors in JavaScript run via such things (what is the file and line number of a piece of script in the onclick attribute of a dynamically inserted element?). This is probably why you get a confusing error message in Chrome. The FireFox error message is different, and also doesn't have a useful line number, although FireBug does show the code which causes the problem.

This snippet of code is taken from your edit function which is in the inline script block of your HTML:

var sub = document.getElementById('submit');
...
sub.setAttribute("onclick", "save(\""+file+"\", document.getElementById('name').value, document.getElementById('text').value");

Note that this sets the onclick attribute of an element to invalid JavaScript code:

<input type="submit" id="submit" onclick="save("data/wasup.htm", document.getElementById('name').value, document.getElementById('text').value">

The JS is:

save("data/wasup.htm", document.getElementById('name').value, document.getElementById('text').value

Note the missing close paren to finish the call to save.

As an aside, inserting onclick attributes is not a very modern or clean way of adding event handlers in JavaScript. Why are you not using the DOM's addEventListener to simply hook up a function to the element? If you were using something like jQuery, this would be simpler still.

This is not an error just simple a message. To execute this message change
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> (example)
to
<!DOCTYPE html>(the Firefox source expect this)

The message was shown in Google Chrome 74 and Opera 60 . After changing it was clear, 0 verbose.
A solution approach

You can't wait() on an object unless the current thread owns that object's monitor. To do that, you must synchronize on it:

class Runner implements Runnable
{
  public void run()
  {
    try
    {
      synchronized(Main.main) {
        Main.main.wait();
      }
    } catch (InterruptedException e) {}
    System.out.println("Runner away!");
  }
}

The same rule applies to notify()/notifyAll() as well.

The Javadocs for wait() mention this:

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Throws:

IllegalMonitorStateException – if the current thread is not the owner of this object's monitor.

And from notify():

A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

The law of the big three is as specified above.

An easy example, in plain English, of the kind of problem it solves:

Non default destructor

You allocated memory in your constructor and so you need to write a destructor to delete it. Otherwise you will cause a memory leak.

You might think that this is job done.

The problem will be, if a copy is made of your object, then the copy will point to the same memory as the original object.

Once, one of these deletes the memory in its destructor, the other will have a pointer to invalid memory (this is called a dangling pointer) when it tries to use it things are going to get hairy.

Therefore, you write a copy constructor so that it allocates new objects their own pieces of memory to destroy.

Assignment operator and copy constructor

You allocated memory in your constructor to a member pointer of your class. When you copy an object of this class the default assignment operator and copy constructor will copy the value of this member pointer to the new object.

This means that the new object and the old object will be pointing at the same piece of memory so when you change it in one object it will be changed for the other objerct too. If one object deletes this memory the other will carry on trying to use it - eek.

To resolve this you write your own version of the copy constructor and assignment operator. Your versions allocate separate memory to the new objects and copy across the values that the first pointer is pointing to rather than its address.

There are tricks like the one described by John; however, Django's template language by design does not support setting a variable (see the "Philosophy" box in Django documentation for templates).
Because of this, the recommended way to change any variable is via touching the Python code.

You are doing it right, so I guess something else is at fault (not export-ing COLUMNS ?).

A trick to debug these cases is to make a specialized command (a closure for programming language guys). Create a shell script named diff-columns doing:

exec /usr/bin/diff -x -y -w -p -W "$COLUMNS" "$@"

and just use

svn diff "$@" --diff-cmd  diff-columns

This way your code is cleaner to read and more modular (top-down approach), and you can test the diff-columns code thouroughly separately (bottom-up approach).

Try to use DateTime.ParseExact method, in which you can specify both of datetime mask and original parsed string. You can read about it here: MSDN: DateTime.ParseExact

Try this :

string myStr = ...
myStr = myStr.Replace("\n", Environment.NewLine)

Try the binascii module

from binascii import unhexlify
b = unhexlify(myhexstr)

If the iFrame content is not yours then the solution below will not work.

With Android all you need to do is to surround the iframe with a DIV and set the height on the div to document.documentElement.clientHeight. IOS, however, is a different animal. Although I have not yet tried Sharon's solution it does seem like a good solution. I did find a simpler solution but it only works with IOS 5.+.

Surround your iframe element with a DIV (lets call it scroller), set the height of the DIV and make sure that the new DIV has the following styling:

$('#scroller').css({'overflow' : 'auto', '-webkit-overflow-scrolling' : 'touch'});

This alone will work but you will notice that in most implementations the content in the iframe goes blank when scrolling and is basically rendered useless. My understanding is that this behavior has been reported as a bug to Apple as early as iOS 5.0. To get around that problem, find the body element in the iframe and add -webkit-transform', 'translate3d(0, 0, 0) like so:

$('#contentIframe').contents().find('body').css('-webkit-transform', 'translate3d(0, 0, 0)');

If your app or iframe is heavy on memory usage you might get a hitchy scroll for which you might need to use Sharon's solution.

Answer: document.activeElement

To do what you want, use document.activeElement.blur()

If you need to support Firefox 2, you can also use this:

function onElementFocused(e)
{
    if (e && e.target)
        document.activeElement = e.target == document ? null : e.target;
} 

if (document.addEventListener) 
    document.addEventListener("focus", onElementFocused, true);

For me this solution works:

edittext.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

This version does not rely on hard-coded, fixed values but sizes relative to the font-size of the div.

http://jsfiddle.net/qod1vstv/

CSS:

.numberCircle {
    font: 32px Arial, sans-serif;

    width: 2em;
    height: 2em;
    box-sizing: initial;

    background: #fff;
    border: 0.1em solid #666;
    color: #666;
    text-align: center;
    border-radius: 50%;    

    line-height: 2em;
    box-sizing: content-box;   
}

HTML:

<div class="numberCircle">30</div>
<div class="numberCircle" style="font-size: 60px">1</div>
<div class="numberCircle" style="font-size: 12px">2</div>

JSON (= JavaScript Object Notation), is a lightweight and fast mechanism to convert Javascript objects into a string and vice versa.

Since Javascripts objects consists of key/value pairs its very easy to use and access JSON that way.

So if we have an object:

var myObj = {
    foo:   'bar',
    base:  'ball',
    deep:  {
       java:  'script'
    }
};

We can convert that into a string by calling window.JSON.stringify(myObj); with the result of "{"foo":"bar","base":"ball","deep":{"java":"script"}}".

The other way around, we would call window.JSON.parse("a json string like the above");.

JSON.parse() returns a javascript object/array on success.

alert(myObj.deep.java);  // 'script'

window.JSON is not natively available in all browser. Some "older" browser need a little javascript plugin which offers the above mentioned functionality. Check http://www.json.org for further information.

You can raise a notice in Postgres as follows:

The three possible solutions suggested here have different use cases.

1. Use .equals when comparing ObjectID on two mongoDocuments like this

   results.userId.equals(AnotherMongoDocument._id)

2. Use .toString() when comparing a string representation of ObjectID to an ObjectID of a mongoDocument. like this

   results.userId === AnotherMongoDocument._id.toString()

The files selected are stored in an array: [input].files

For example, you can access the items

// assuming there is a file input with the ID `my-input`...
var files = document.getElementById("my-input").files;

for (var i = 0; i < files.length; i++)
{
 alert(files[i].name);
}

For jQuery-comfortable people, it's similarly easy

// assuming there is a file input with the ID `my-input`...
var files = $("#my-input")[0].files;

for (var i = 0; i < files.length; i++)
{
 alert(files[i].name);
}

The angular.forEach loop can't break on a condition match.

My personal advice is to use a NATIVE FOR loop instead of angular.forEach.

The NATIVE FOR loop is around 90% faster then other for loops.

USE FOR loop IN ANGULAR:

var numbers = [0, 1, 2, 3, 4, 5];

for (var i = 0, len = numbers.length; i < len; i++) {
  if (numbers[i] === 1) {
    console.log('Loop is going to break.'); 
    break;
  }
  console.log('Loop will continue.');
}

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"

in my .html

<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">

then in my component.ts

reSearch(newValue: string) {
    //this.searchText would equal the new value
    //handle my filtering with the new value
}

Try like this format and use "width" attribute to manage the image size, it is simple. JavaScript can be implemented in element too.

<button><img src=""></button>

Timer.Elapsed expects method of specific signature (with arguments object and EventArgs). If you want to use your PlayMusicEvent method with additional argument evaluated during event registration, you can use lambda expression as an adapter:

myTimer.Elapsed += new ElapsedEventHandler((sender, e) => PlayMusicEvent(sender, e, musicNote));

Edit: you can also use shorter version:

myTimer.Elapsed += (sender, e) => PlayMusicEvent(sender, e, musicNote);

THIS IS FOR BEGINNERS,

Python automatically compiles your script to compiled code, so called byte code, before running it.

Running a script is not considered an import and no .pyc will be created.

For example, if you have a script file abc.py that imports another module xyz.py, when you run abc.py, xyz.pyc will be created since xyz is imported, but no abc.pyc file will be created since abc.py isn’t being imported.

If you need to create a .pyc file for a module that is not imported, you can use the py_compile and compileall modules.

The py_compile module can manually compile any module. One way is to use the py_compile.compile function in that module interactively:

>>> import py_compile
>>> py_compile.compile('abc.py')

This will write the .pyc to the same location as abc.py (you can override that with the optional parameter cfile).

You can also automatically compile all files in a directory or directories using the compileall module.

python -m compileall

If the directory name (the current directory in this example) is omitted, the module compiles everything found on sys.path

The exception is due to your JAXB (JSR-222) implementation believing that there are two things mapped with the same name (a field and a property). There are a couple of options for your use case:

OPTION #1 - Annotate the Field with @XmlAccessorType(XmlAccessType.FIELD)

If you want to annotation the field then you should specify @XmlAccessorType(XmlAccessType.FIELD)

Fields.java:

package forum10795793;

import java.util.*;
import javax.xml.bind.annotation.*;

@XmlRootElement(name = "fields")
@XmlAccessorType(XmlAccessType.FIELD)
public class Fields {

    @XmlElement(name = "field")
    List<Field> fields = new ArrayList<Field>();

    public List<Field> getFields() {
        return fields;
    }

    public void setFields(List<Field> fields) {
        this.fields = fields;
    }

}

Field.java:

package forum10795793;

import javax.xml.bind.annotation.*;

@XmlAccessorType(XmlAccessType.FIELD)
public class Field {

    @XmlAttribute(name = "mappedField")
    String mappedField;

    public String getMappedField() {
        return mappedField;
    }

    public void setMappedField(String mappedField) {
        this.mappedField = mappedField;
    }

}

OPTION #2 - Annotate the Properties

The default accessor type is XmlAccessType.PUBLIC. This means that by default JAXB implementations will map public fields and accessors to XML. Using the default setting you should annotate the public accessors where you want to override the default mapping behaviour.

Fields.java:

package forum10795793;

import java.util.*;
import javax.xml.bind.annotation.*;

@XmlRootElement(name = "fields")
public class Fields {

    List<Field> fields = new ArrayList<Field>();

    @XmlElement(name = "field")
    public List<Field> getFields() {
        return fields;
    }

    public void setFields(List<Field> fields) {
        this.fields = fields;
    }

}

Field.java:

package forum10795793;

import javax.xml.bind.annotation.*;

public class Field {

    String mappedField;

    @XmlAttribute(name = "mappedField")
    public String getMappedField() {
        return mappedField;
    }

    public void setMappedField(String mappedField) {
        this.mappedField = mappedField;
    }

}

add_header works as well with proxy_pass as without. I just today set up a configuration where I've used exactly that directive. I have to admit though that I've struggled as well setting this up without exactly recalling the reason, though.

Right now I have a working configuration and it contains the following (among others):

server {
    server_name  .myserver.com
    location / {
        proxy_pass  http://mybackend;
        add_header  X-Upstream  $upstream_addr;
    }
}

Before nginx 1.7.5 add_header worked only on successful responses, in contrast to the HttpHeadersMoreModule mentioned by Sebastian Goodman in his answer.

Since nginx 1.7.5 you can use the keyword always to include custom headers even in error responses. For example:

add_header X-Upstream $upstream_addr always;

Limitation: You cannot override the server header value using add_header.

You can check it with utility method "isEmpty" from TextUtils,

isEmpty(CharSequence str) method check both condition, for null and length.

public static boolean isEmpty(CharSequence str) {
     if (str == null || str.length() == 0)
        return true;
     else
        return false;
}

Your example would be:

int num1 = 1;
int num2 = 1;

num1 = num2 = 5;

You can use GNU date command as shown below

Getting Date In the Past

To get yesterday and earlier day in the past use string day ago:

date --date='yesterday'

date --date='1 day ago'

date --date='10 day ago'

date --date='10 week ago'

date --date='10 month ago'

date --date='10 year ago'

Getting Date In the Future

To get tomorrow and day after tomorrow (tomorrow+N) use day word to get date in the future as follows:

date --date='tomorrow'

date --date='1 day'

date --date='10 day'

date --date='10 week'

date --date='10 month'

date --date='10 year'

To summarize some of the fine answers above: Maven is designed to build modules and copy the results to a Maven repository. Any copying of modules to a deployment/installer-input directory must be done outside the context of Maven's core functionality, e.g. with the Ant/Maven copy command.

In my case having loadView() interrupted
this code: self.edgesForExtendedLayout = UIRectEdgeNone

but after deleting loadView() everything worked fine

A of couple things that need to happen...

1. The view controller needs to extend the type UITableViewDelegate

2. The view controller needs to include the didSelectRowAt function.

3. The table view must have the view controller assigned as its delegate.

Below is one place where assigning the delegate could take place (within the view controller).

override func loadView() {
    tableView.dataSource = self
    tableView.delegate = self
    view = tableView
}

And a simple implementation of the didSelectRowAt function.

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    print("row: \(indexPath.row)")
}

What does the DTD have to say?

If the XML file is for communicating with other existing software (e.g., SOAP), then check that software for what it expects.

If the XML file is for serialisation or communication with non-existing software (e.g., the one you're writing), you can define it. In which case, I'd suggest something that is both easy to parse in your language(s) of choice, and easy to read for humans. e.g., if your language (whether VB.NET or C#.NET or whatever) allows you to parse ISO dates (YYYY-MM-DD) easily, that's the one I'd suggest.

Last-Modified : The last modified date for the requested object

If-Modified-Since : Allows a 304 Not Modified to be returned if last modified date is unchanged.

ETag : An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned.

If-None-Match : Allows a 304 Not Modified to be returned if ETag is unchanged.

the browser store cache with a date(Last-Modified) or id(ETag), when you need to request the URL again, the browser send request message with the header:

the server will return 304 when the if statement is False, and browser will use cache.

I am not sure if I understand you correctly, does this help?

ps --ppid <pid of the parent>

I suggest a more dynamic approach, without html coding into the page, keep it strictly JS:

$("a.AS-POST").on('click', e => {
  e.preventDefault()
  let frm = document.createElement('FORM')
  frm.id='frm_'+Math.random()
  frm.method='POST'
  frm.action=e.target.href
  document.body.appendChild(frm)
  frm.submit()
})

I don't know what you mean by "data dont get lost". Here's how you pass a normal 2D array to a function:

void myfunc(int arr[M][N]) { // M is optional, but N is required
  ..
}

int main() {
  int somearr[M][N];
  ...
  myfunc(somearr);
  ...
}

Here you go.

SELECT
   column1, 
   column2
FROM
   viewWhatever
WHERE
CASE 
    WHEN @locationType = 'location' AND account_location = @locationID THEN 1
    WHEN @locationType = 'area' AND xxx_location_area = @locationID THEN 1
    WHEN @locationType = 'division' AND xxx_location_division = @locationID THEN 1
    ELSE 0
END = 1

Settings (Ctrl+Alt+s)--> Apprarance-->Override default fonts by(not recommended):

then change Size to 16+.

Note that a jar file is a Zip file, and any Zip tool (such as 7-Zip) can look inside the jar.

function loadEditor(id)
{
    var instance = CKEDITOR.instances[id];
    if(instance)
    {
        CKEDITOR.remove(instance);
    }
    CKEDITOR.replace(id);
}

As @Yoshi said, from angular 1.1.5 you can use-it without any change.

If you use angular < 1.1.5, you can use ng-class.

.largeWidth {
    width: 100%;
}

.smallWidth {
    width: 0%;
}

// [...]

ng-class="{largeWidth: myVar == 'ok', smallWidth: myVar != 'ok'}"

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

I personally would add a click handler to the child element that did nothing but stop the propagation of the click. So it would look something like:

$('.example > div').click(function (e) {
    e.stopPropagation();
});

The canonical T-SQL (SqlServer) answer is to use a DELETE with JOIN as such

DELETE o
FROM Orders o
INNER JOIN Customers c
    ON o.CustomerId = c.CustomerId
WHERE c.FirstName = 'sklivvz'

This will delete all orders which have a customer with first name Sklivvz.

had this problem in kali. deleted go and reinstalled and now it works perfectly.

Also, make sure that your environment variable is composed only by UPPER CASE LETTERS.... I don't know why (the documentation doesn't say nothing explicit about it, at least the link provided by @Andrew White), but if the variable is a lower case word (e.g. env.dummy), the variable always came empty or null...

i was struggling with this like an hour, until I decided to try an UPPER CASE VARIABLE, and problem solved.

OK Variables Examples:

• DUMMY
• DUMMY_ONE
• JBOSS_SERVER_PATH

(NOTE: I was using maven v3.0.5)

I Hope that this can help someone....

Try the following:

@MvcHtmlString.Create(Model.CommentText.Replace(Environment.NewLine, "<br />"))

Update:

According to marcind's comment on this related question, the ASP.NET MVC team is looking to implement something similar to the <%: and <%= for the Razor view engine.

Update 2:

We can turn any question about HTML encoding into a discussion on harmful user inputs, but enough of that already exists.

Anyway, take care of potential harmful user input.

@MvcHtmlString.Create(Html.Encode(Model.CommentText).Replace(Environment.NewLine, "<br />"))

Update 3 (Asp.Net MVC 3):

@Html.Raw(Html.Encode(Model.CommentText).Replace("\n", "<br />"))

Example query:

DELETE FROM Table
WHERE ID NOT IN
(
SELECT MIN(ID)
FROM Table
GROUP BY Field1, Field2, Field3, ...
)

Here fields are column on which you want to group the duplicate rows.

If you just want the unix timestamp, create an extension:

extension Date {
    func currentTimeMillis() -> Int64 {
        return Int64(self.timeIntervalSince1970 * 1000)
    }
}

Then you can use it just like in other programming languages:

let timestamp = Date().currentTimeMillis()

Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"

@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;

Doing something with each child looks like: this.customComponentChildren.forEach((child) => { child.stuff = 'y' })

Brief code but full-featured

The following is a hybrid jQuery solution that formats each data "record" into an HTML element and uses the data's properties as HTML attribute values.

The jquery each runs the inner loop; I needed the regular JavaScript for on the outer loop to be able to grab the property name (instead of value) for display as the heading. According to taste it can be modified for slightly different behaviour.

This is only 5 main lines of code but wrapped onto multiple lines for display:

$.get("data.php", function(data){

    for (var propTitle in data) {

        $('<div></div>') 
            .addClass('heading')
            .insertBefore('#contentHere')
            .text(propTitle);

            $(data[propTitle]).each(function(iRec, oRec) {

                $('<div></div>')
                    .addClass(oRec.textType)
                    .attr('id', 'T'+oRec.textId)
                    .insertBefore('#contentHere')
                    .text(oRec.text);
            });
    }

});

Produces the output

(Note: I modified the JSON data text values by prepending a number to ensure I was displaying the proper records in the proper sequence - while "debugging")

<div class="heading">
    justIn
</div>
<div id="T123" class="Greeting">
    1Hello
</div>
<div id="T514" class="Question">
    1What's up?
</div>
<div id="T122" class="Order">
    1Come over here
</div>
<div class="heading">

<div id="T1255" class="Greeting">
    2Hello

Apply a style sheet

<style>
.heading { font-size: 24px; text-decoration:underline }
.Greeting { color: green; }
.Question { color: blue; }
.Order { color: red; }
</style>

to get a "beautiful" looking set of data

More Info
The JSON data was used in the following way:

for each category (key name the array is held under):

• the key name is used as the section heading (e.g. justIn)

for each object held inside an array:

• 'text' becomes the content of a div
• 'textType' becomes the class of the div (hooked into a style sheet)
• 'textId' becomes the id of the div
• e.g. <div id="T122" class="Order">Come over here</div>

$('#radio1').removeAttr('checked');
$('#radio2').removeAttr('checked');
$('#radio3').removeAttr('checked');
$('#radio4').removeAttr('checked');

Or

$('input[name="correctAnswer"]').removeAttr('checked');

According to the Python os module documentation os.popen has been deprecated since Python 2.6.

I think the solution for modern Python is to use check_output() from the subprocess module.

From the subprocess Python documentation:

subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, universal_newlines=False) Run command with arguments and return its output as a byte string.

If the return code was non-zero it raises a CalledProcessError. The CalledProcessError object will have the return code in the returncode attribute and any output in the output attribute.

If you run through the following code in Python 2.7 (or later):

import subprocess

try:
    print subprocess.check_output(["ping", "-n", "2", "-w", "2", "1.1.1.1"])
except subprocess.CalledProcessError, e:
    print "Ping stdout output:\n", e.output

You should see an output that looks something like this:

Ping stdout output:

Pinging 1.1.1.1 with 32 bytes of data:
Request timed out.
Request timed out.

Ping statistics for 1.1.1.1:
Packets: Sent = 2, Received = 0, Lost = 2 (100% loss),

The e.output string can be parsed to suit the OPs needs.

If you want the returncode or other attributes, they are in CalledProccessError as can be seen by stepping through with pdb

(Pdb)!dir(e)

Some trick to debug bash scripts:

Using set -[nvx]

In addition to

set -x

and

set +x

for stopping dump.

I would like to speak about set -v wich dump as smaller as less developped output.

bash <<<$'set -x\nfor i in {0..9};do\n\techo $i\n\tdone\nset +x' 2>&1 >/dev/null|wc -l
21

for arg in x v n nx nv nvx;do echo "- opts: $arg"
    bash 2> >(wc -l|sed s/^/stderr:/) > >(wc -l|sed s/^/stdout:/) <<eof
        set -$arg
        for i in {0..9};do
            echo $i
          done
        set +$arg
        echo Done.
eof
    sleep .02
  done
- opts: x
stdout:11
stderr:21
- opts: v
stdout:11
stderr:4
- opts: n
stdout:0
stderr:0
- opts: nx
stdout:0
stderr:0
- opts: nv
stdout:0
stderr:5
- opts: nvx
stdout:0
stderr:5

Dump variables or tracing on the fly

For testing some variables, I use sometime this:

bash <(sed '18ideclare >&2 -p var1 var2' myscript.sh) args

for adding:

declare >&2 -p var1 var2

at line 18 and running resulting script (with args), without having to edit them.

of course, this could be used for adding set [+-][nvx]:

bash <(sed '18s/$/\ndeclare -p v1 v2 >\&2/;22s/^/set -x\n/;26s/^/set +x\n/' myscript) args

will add declare -p v1 v2 >&2 after line 18, set -x before line 22 and set +x before line 26.

little sample:

bash <(sed '2,3s/$/\ndeclare -p LINENO i v2 >\&2/;5s/^/set -x\n/;7s/^/set +x\n/' <(
        seq -f 'echo $@, $((i=%g))' 1 8)) arg1 arg2
arg1 arg2, 1
arg1 arg2, 2
declare -i LINENO="3"
declare -- i="2"
/dev/fd/63: line 3: declare: v2: not found
arg1 arg2, 3
declare -i LINENO="5"
declare -- i="3"
/dev/fd/63: line 5: declare: v2: not found
arg1 arg2, 4
+ echo arg1 arg2, 5
arg1 arg2, 5
+ echo arg1 arg2, 6
arg1 arg2, 6
+ set +x
arg1 arg2, 7
arg1 arg2, 8

Note: Care about $LINENO will be affected by on-the-fly modifications!

( To see resulting script whithout executing, simply drop bash <( and ) arg1 arg2 )

Step by step, execution time

Have a look at my answer about how to profile bash scripts

You should have :

<div id="header">
<?php 
    // integer starts at 0 before counting
    $i = 0; 
    $dir = 'uploads/';
    if ($handle = opendir($dir)) {
        while (($file = readdir($handle)) !== false){
            if (!in_array($file, array('.', '..')) && !is_dir($dir.$file)) 
                $i++;
        }
    }
    // prints out how many were in the directory
    echo "There were $i files";
?>
</div>

Never mind, I found it in the docs:

-g/--globoff
              This  option  switches  off  the "URL globbing parser". When you set this option, you can
              specify URLs that contain the letters {}[] without having them being interpreted by  curl
              itself.  Note  that  these  letters  are not normal legal URL contents but they should be
              encoded according to the URI standard.

Although JS implementations might keep track of such a value internally, there's no standard way to get it.

In the past, Mozilla's Javascript variant exposed the non-standard __count__, but it has been removed with version 1.8.5.

For cross-browser scripting you're stuck with explicitly iterating over the properties and checking hasOwnProperty():

function countProperties(obj) {
    var count = 0;

    for(var prop in obj) {
        if(obj.hasOwnProperty(prop))
            ++count;
    }

    return count;
}

In case of ECMAScript 5 capable implementations, this can also be written as (Kudos to Avi Flax)

function countProperties(obj) {
    return Object.keys(obj).length;
}

Keep in mind that you'll also miss properties which aren't enumerable (eg an array's length).

If you're using a framework like jQuery, Prototype, Mootools, $whatever-the-newest-hype, check if they come with their own collections API, which might be a better solution to your problem than using native JS objects.

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName to be the name of the file you wish to open.

Private Const TargetWBName As String = "myworkbook.xlsx"

'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
    WorkbookOpen = False
    On Error GoTo WorkBookNotOpen
    If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
        WorkbookOpen = True
        Exit Function
    End If
WorkBookNotOpen:
End Function

Private Sub Workbook_Open()
    'Check if our target workbook is open
    If WorkbookOpen(TargetWBName) = False Then
        'set calculation to manual
        Application.Calculation = xlCalculationManual
        Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
        DoEvents
        Me.Close False
    End If
End Sub

Set the constant 'TargetWBName' to be the name of the workbook that you wish to open. This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself. *NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True after Me.Close

I solved the same problem following this example:

This example uses the jQuery JavaScript library.

First, create an Ajax icon using the AjaxLoad site.
Then add the following to your HTML :

<img src="/images/loading.gif" id="loading-indicator" style="display:none" />

And the following to your CSS file:

#loading-indicator {
  position: absolute;
  left: 10px;
  top: 10px;
}

Lastly, you need to hook into the Ajax events that jQuery provides; one event handler for when the Ajax request begins, and one for when it ends:

$(document).ajaxSend(function(event, request, settings) {
    $('#loading-indicator').show();
});

$(document).ajaxComplete(function(event, request, settings) {
    $('#loading-indicator').hide();
});

This solution is from the following link. How to display an animated icon during Ajax request processing

If you have the generated SSH key for your project from GitLab you can add it to your keychain in OS X via terminal.

ssh-add -K <ssh_generated_key_file.txt>

Once executed you will be asked for the passphrase that you entered when creating the SSH key.

Once the SSH key is in the keychain you can paste the URL from GitLab into Sourcetree like you normally would to clone the project.

This should do the trick.

$(textInput).closest("tr").hide();

The statement def foo(client_id: str) -> list or bool: when evaluated is equivalent to def foo(client_id: str) -> list: and will therefore not do what you want.

The native way to describe a "either A or B" type hint is Union (thanks to Bhargav Rao):

def foo(client_id: str) -> Union[list, bool]:

I do not want to be the "Why do you want to do this anyway" guy, but maybe having 2 return types isn't what you want:

If you want to return a bool to indicate some type of special error-case, consider using Exceptions instead. If you want to return a bool as some special value, maybe an empty list would be a good representation. You can also indicate that None could be returned with Optional[list]

To just get the index column names df.index.names will work for both a single Index or MultiIndex as of the most recent version of pandas.

As someone who found this while trying to find the best way to get a list of index names + column names, I would have found this answer useful:

names = list(filter(None, df.index.names + df.columns.values.tolist()))

This works for no index, single column Index, or MultiIndex. It avoids calling reset_index() which has an unnecessary performance hit for such a simple operation. I'm surprised there isn't a built in method for this (that I've come across). I guess I run into needing this more often because I'm shuttling data from databases where the dataframe index maps to a primary/unique key, but is really just another column to me.

I wrote a plugin called hasEventListener which exactly does that :

http://github.com/sebastien-p/jquery.hasEventListener

Hope this helps.

It's getting even faster if you don't read in small 8 byte chunks but put a loop around, reading a larger chunk. I reduced the average comparison time to 1/4.

    public static bool FilesContentsAreEqual(FileInfo fileInfo1, FileInfo fileInfo2)
    {
        bool result;

        if (fileInfo1.Length != fileInfo2.Length)
        {
            result = false;
        }
        else
        {
            using (var file1 = fileInfo1.OpenRead())
            {
                using (var file2 = fileInfo2.OpenRead())
                {
                    result = StreamsContentsAreEqual(file1, file2);
                }
            }
        }

        return result;
    }

    private static bool StreamsContentsAreEqual(Stream stream1, Stream stream2)
    {
        const int bufferSize = 1024 * sizeof(Int64);
        var buffer1 = new byte[bufferSize];
        var buffer2 = new byte[bufferSize];

        while (true)
        {
            int count1 = stream1.Read(buffer1, 0, bufferSize);
            int count2 = stream2.Read(buffer2, 0, bufferSize);

            if (count1 != count2)
            {
                return false;
            }

            if (count1 == 0)
            {
                return true;
            }

            int iterations = (int)Math.Ceiling((double)count1 / sizeof(Int64));
            for (int i = 0; i < iterations; i++)
            {
                if (BitConverter.ToInt64(buffer1, i * sizeof(Int64)) != BitConverter.ToInt64(buffer2, i * sizeof(Int64)))
                {
                    return false;
                }
            }
        }
    }
}

I posted a fix for this here

You can use this function to modify JSON.stringify to encode arrays, just post it near the beginning of your script (check the link above for more detail):

// Upgrade for JSON.stringify, updated to allow arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

We can simply state that when a superclass is inherited, then the private members of superclass actually become private members of the subclass and cannot be further inherited or are inacessible to the objects of subclass.

You can get the all record of the date '2016-07-14' by using it

 whereDate('date','=','2016-07-14')

Or use the another code for dynamic date

whereDate('date',$date)

You can access a string using [], as you do for arrays:

$stringLength = strlen($str);
for ($i = 0; $i < $stringLength; $i++)
    $char = $str[$i];

In Python, a distinction between expressions and statements is rigidly enforced, in contrast to languages such as Common Lisp, Scheme, or Ruby.

Wikipedia

So by introducing such operators, you would break the expression/statement split.

For the same reason you can't write

if x = 0:
  y = 1

as you can in some other languages where such distinction is not preserved.

You can read the whole file and split lines using str.splitlines:

temp = file.read().splitlines()

Or you can strip the newline by hand:

temp = [line[:-1] for line in file]

Note: this last solution only works if the file ends with a newline, otherwise the last line will lose a character.

This assumption is true in most cases (especially for files created by text editors, which often do add an ending newline anyway).

If you want to avoid this you can add a newline at the end of file:

with open(the_file, 'r+') as f:
    f.seek(-1, 2)  # go at the end of the file
    if f.read(1) != '\n':
        # add missing newline if not already present
        f.write('\n')
        f.flush()
        f.seek(0)
    lines = [line[:-1] for line in f]

Or a simpler alternative is to strip the newline instead:

[line.rstrip('\n') for line in file]

Or even, although pretty unreadable:

[line[:-(line[-1] == '\n') or len(line)+1] for line in file]

Which exploits the fact that the return value of or isn't a boolean, but the object that was evaluated true or false.

The readlines method is actually equivalent to:

def readlines(self):
    lines = []
    for line in iter(self.readline, ''):
        lines.append(line)
    return lines

# or equivalently

def readlines(self):
    lines = []
    while True:
        line = self.readline()
        if not line:
            break
        lines.append(line)
    return lines

Since readline() keeps the newline also readlines() keeps it.

Note: for symmetry to readlines() the writelines() method does not add ending newlines, so f2.writelines(f.readlines()) produces an exact copy of f in f2.

Try this:

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

If you want to remove the zero digits just before to display on the page or template.

You can use the sprintf() function

sprintf('%g','125.00');
//125

??sprintf('%g','966.70');
//966.7

????sprintf('%g',844.011);
//844.011

For me what worked by combining all the posts I have read is:

1.Enable OLE automation - if not enabled

sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE;  
GO  
sp_configure 'Ole Automation Procedures', 1;  
GO  
RECONFIGURE;  
GO

2.Create a folder where the generated files will be stored:

C:\GREGTESTING

3.Create DocTable that will be used for file generation and store there the blobs in Doc_Content

CREATE TABLE [dbo].[Document](
    [Doc_Num] [numeric](18, 0) IDENTITY(1,1) NOT NULL,
    [Extension] [varchar](50) NULL,
    [FileName] [varchar](200) NULL,
    [Doc_Content] [varbinary](max) NULL   
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 

INSERT [dbo].[Document] ([Extension] ,[FileName] , [Doc_Content] )
    SELECT 'pdf', 'SHTP Notional hire - January 2019.pdf', 0x....(varbinary blob)

Important note!

Don't forget to add in Doc_Content column the varbinary of file you want to generate!

4.Run the below script

DECLARE @outPutPath varchar(50) = 'C:\GREGTESTING'
, @i bigint
, @init int
, @data varbinary(max) 
, @fPath varchar(max)  
, @folderPath  varchar(max)

--Get Data into temp Table variable so that we can iterate over it 
DECLARE @Doctable TABLE (id int identity(1,1), [Doc_Num]  varchar(100) , [FileName]  varchar(100), [Doc_Content] varBinary(max) )



INSERT INTO @Doctable([Doc_Num] , [FileName],[Doc_Content])
Select [Doc_Num] , [FileName],[Doc_Content] FROM  [dbo].[Document]



SELECT @i = COUNT(1) FROM @Doctable   

WHILE @i >= 1   

BEGIN    

SELECT 
    @data = [Doc_Content],
    @fPath = @outPutPath + '\' + [Doc_Num] +'_' +[FileName],
    @folderPath = @outPutPath + '\'+ [Doc_Num]
FROM @Doctable WHERE id = @i

EXEC sp_OACreate 'ADODB.Stream', @init OUTPUT; -- An instace created
EXEC sp_OASetProperty @init, 'Type', 1;  
EXEC sp_OAMethod @init, 'Open'; -- Calling a method
EXEC sp_OAMethod @init, 'Write', NULL, @data; -- Calling a method
EXEC sp_OAMethod @init, 'SaveToFile', NULL, @fPath, 2; -- Calling a method
EXEC sp_OAMethod @init, 'Close'; -- Calling a method
EXEC sp_OADestroy @init; -- Closed the resources
print 'Document Generated at - '+  @fPath   

--Reset the variables for next use
SELECT @data = NULL  
, @init = NULL
, @fPath = NULL  
, @folderPath = NULL
SET @i -= 1
END

There are many examples in the Android (AOSP) sources. For example, PackageInfo class has a boolean member requiredForAllUsers and it is serialized as follows:

public void writeToParcel(Parcel dest, int parcelableFlags) {
    ...
    dest.writeInt(requiredForAllUsers ? 1 : 0);
    ...
}

private PackageInfo(Parcel source) {
    ...
    requiredForAllUsers = source.readInt() != 0;
    ...
}

You can not really add the x-iframe in your HTML body as it has to be provided by the site owner and it lies within the server rules.

What you can probably do is create a PHP file which loads the content of target URL and iframe that php URL, this should work smoothly.

In reply to James Craig Burley's answer. In order to make a clean and re-usable design, one might choose for a more object oriented approach. This way methods can be safely bound to the types of the specified map. To me this approach feels cleaner and organized.

Example:

package main

import (
    "fmt"
    "sort"
)

type myIntMap map[int]string

func (m myIntMap) sort() (index []int) {
    for k, _ := range m {
        index = append(index, k)
    }
    sort.Ints(index)
    return
}

func main() {
    m := myIntMap{
        1:  "one",
        11: "eleven",
        3:  "three",
    }
    for _, k := range m.sort() {
        fmt.Println(m[k])
    }
}

Extended playground example with multiple map types.

Important note

In all cases, the map and the sorted slice are decoupled from the moment the for loop over the map range is finished. Meaning that, if the map gets modified after the sorting logic, but before you use it, you can get into trouble. (Not thread / Go routine safe). If there is a change of parallel Map write access, you'll need to use a mutex around the writes and the sorted for loop.

mutex.Lock()
for _, k := range m.sort() {
    fmt.Println(m[k])
}
mutex.Unlock()

just add display: inline-block; property and removed width.

When using Webpack you need to require images in order for Webpack to process them, which would explain why external images load while internal do not, so instead of <img src={"/images/resto.png"} /> you need to use <img src={require('/images/image-name.png')} /> replacing image-name.png with the correct image name for each of them. That way Webpack is able to process and replace the source img.

To add on nathan gonzalez answer, please note you need to assign the replaced object after calling replace function since it is not a mutator function:

myString = myString.replace('username1','');

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.

Update:

It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.

Here is a very simple piece of C# code to test the CommandTimeout with. It creates a new command which will wait for 2 seconds. Set the CommandTimeout to 1 second and you will see an exception when running it. Setting the CommandTimeout to either 0 or something higher than 2 will run fine. By the way, the default CommandTimeout is 30 seconds.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Data.SqlClient;

namespace ConsoleApplication1
{
  class Program
  {
    static void Main(string[] args)
    {
      var builder = new SqlConnectionStringBuilder();
      builder.DataSource = "localhost";
      builder.IntegratedSecurity = true;
      builder.InitialCatalog = "master";

      var connectionString = builder.ConnectionString;

      using (var connection = new SqlConnection(connectionString))
      {
        connection.Open();

        using (var command = connection.CreateCommand())
        {
          command.CommandText = "WAITFOR DELAY '00:00:02'";
          command.CommandTimeout = 1;

          command.ExecuteNonQuery();
        }
      }
    }
  }
}

If you're using Visual Studio (this might work in Eclipse also, but I never tried) and you copy & paste into Microsoft Word (or any other microsoft product) it will paste the code in whatever color your IDE had. Then you just need to copy the text out of word and into your desired application and it will paste as rich text.

I've only seen this work across Visual Studio to other Microsoft products though so I don't know if it will be any help.

This is very simple approach. The Advantage is you can get keys as well:

for (var key in array) {
    var value = array[key];
    console.log(key, value);
}

For ES6:

array.forEach(value => {
  console.log(value)
})  

For ES6: (If you want value, index and the array itself)

array.forEach((value, index, self) => {
  console.log(value, index, self)
})  

char members[255] = {0};

I've encountered similar problem on Ubuntu 16.04 and was able to solve it by creating a folder named "default-java" in /usr/lib/jvm and copying into it all the contents of the /usr/lib/jvm/java-8-oracle. I opted for this solution as correcting JAVA_HOME environment variable turned out to be of no use.

It's more convention than anything else.

• T is meant to be a Type
• E is meant to be an Element (List<E>: a list of Elements)
• K is Key (in a Map<K,V>)
• V is Value (as a return value or mapped value)

They are fully interchangeable (conflicts in the same declaration notwithstanding).

For those deploying a docker image and using a locale that isn't shown in the locale -a command, add this line to your Dockerfile
RUN apt-get install -y locales

This should add all locales to your image, I used de_DE which is not part of AWS default Ubuntu server.

this works: select * from table where column like '%(hit enter)%'

Ignore the brackets and hit enter to introduce new line.

You can add elements to your environment by using

os.environ['LD_LIBRARY_PATH'] = 'my_path'

and run subprocesses in a shell (that uses your os.environ) by using

subprocess.call('sqsub -np ' + var1 + '/homedir/anotherdir/executable', shell=True)

I use the following class which implements the Runnable interface. With this class you can easily create new threads with arguments

public abstract class RunnableArg implements Runnable {

    Object[] m_args;

    public RunnableArg() {
    }

    public void run(Object... args) {
        setArgs(args);
        run();
    }

    public void setArgs(Object... args) {
        m_args = args;
    }

    public int getArgCount() {
        return m_args == null ? 0 : m_args.length;
    }

    public Object[] getArgs() {
        return m_args;
    }
}

You can use normal file operation to create an error log. Just refer this and input this link: PHP File Handling

Use the length property or the size method to find out how many items are in a jQuery collection. Use the descendant selector to select all <option>'s within a <select>.

HTML:

<select id="myDropDown">
<option>1</option>
<option>2</option>
.
.
.
</select>

JQuery:

var numberOfOptions = $('select#myDropDown option').length

And a quick note, often you will need to do something in jquery for a very specific thing, but you first need to see if the very specific thing exists. The length property is the perfect tool. example:

   if($('#myDropDown option').length > 0{
      //do your stuff..
    } 

This 'translates' to "If item with ID=myDropDown has any descendent 'option' s, go do what you need to do.

Remember, you are NOT allowed to do this.

class foo():
    def print_hello(self):
        print("Hello")       # This next line will produce an ERROR!
    self.print_hello()       # <---- it calls a class function, inside a class,
                             # but outside a class function. Not allowed.

You must call a class function from either outside the class, or from within a function in that class.

Vi or Vim?

Anyway, the following command works for Vim in 'nocompatible' mode. That is, I suppose, almost pure vi.

:join!

If you want to do it from normal command use

gJ

With 'gJ' you join lines as is -- without adding or removing whitespaces:

S<Switch_ID>_F<File type>
_ID<ID number>_T<date+time>_O<Original File name>.DAT

Result:

S<Switch_ID>_F<File type>_ID<ID number>_T<date+time>_O<Original File name>.DAT

With 'J' command you will have:

S<Switch_ID>_F<File type> _ID<ID number>_T<date+time>_O<Original File name>.DAT

Note space between type> and _ID.

You could make a batch file with the following code:

start javaw -jar JarFile.jar

and convert the .bat to an .exe using any .bat to .exe converter.

Instead of creating your own directive, it's possible to simply use javascript functions to accomplish a focus.

Here is an example.

In the html file:

<input type="text" id="myInputId" />

In a file javascript, in a controller for example, where you want to activate the focus:

document.getElementById("myInputId").focus();

Depends on whether you want the annotations route or the bean XML definition route.

Say you had the beans defined in your applicationContext.xml:

<beans ...>

    <bean id="userService" class="com.foo.UserServiceImpl"/>

    <bean id="fooController" class="com.foo.FooController"/>

</beans>

The autowiring happens when the application starts up. So, in fooController, which for arguments sake wants to use the UserServiceImpl class, you'd annotate it as follows:

public class FooController {

    // You could also annotate the setUserService method instead of this
    @Autowired
    private UserService userService;

    // rest of class goes here
}

When it sees @Autowired, Spring will look for a class that matches the property in the applicationContext, and inject it automatically. If you have more than one UserService bean, then you'll have to qualify which one it should use.

If you do the following:

UserService service = new UserServiceImpl();

It will not pick up the @Autowired unless you set it yourself.

For Swift 5

1) Confirm the delegate to the AppDelegate with UNUserNotificationCenterDelegate

2) UNUserNotificationCenter.current().delegate = self in didFinishLaunch

3) Implement the below the method in AppDelegate.

That's it!

If you have not set the type of a file, Git tries to determine it automatically and a file with really long lines and maybe some wide characters (e.g. Unicode) is treated as binary. With the .gitattributes file you can define how Git interpretes the file. Setting the diff attribute manually lets Git interprete the file content as text and will do an usual diff.

Just add a .gitattributes to your repository root folder and set the diff attribute to the paths or files. Here's an example:

src/Acme/DemoBundle/Resources/public/js/i18n/* diff
doc/Help/NothingToSay.yml                      diff
*.css                                          diff

If you want to check if there are attributes set on a file, you can do that with the help of git check-attr

git check-attr --all -- src/my_file.txt

Another nice reference about Git attributes could be found here.

&something gives you the address of the std::vector object, not the address of the data it holds. &something.begin() gives you the address of the iterator returned by begin() (as the compiler warns, this is not technically allowed because something.begin() is an rvalue expression, so its address cannot be taken).

Assuming the container has at least one element in it, you need to get the address of the initial element of the container, which you can get via

• &something[0] or &something.front() (the address of the element at index 0), or

• &*something.begin() (the address of the element pointed to by the iterator returned by begin()).

In C++11, a new member function was added to std::vector: data(). This member function returns the address of the initial element in the container, just like &something.front(). The advantage of this member function is that it is okay to call it even if the container is empty.

data_cl = reg_data.exceptAll(data_fr)

Use Element.classList

document.getElementById('hello').classList.add('someClass');

The .add method will only add the class if it doesn't already exist on the element. So no need to worry about duplicate class names.

If it's one script it's fine with the above solution.

I would set up Ansible to do the Job. It works in the same way (Ansible uses ssh to execute the scripts on the remote machine for both Unix or Windows).

It will be more structured and maintainable.

Datetime formatting is performed by the org.joda.time.format.DateTimeFormatter class. Three classes provide factory methods to create formatters, and this is one. The others are ISODateTimeFormat and DateTimeFormatterBuilder.

DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MMM-dd");
LocalDate lDate = new LocalDate().parse("2005-nov-12",format);

final org.joda.time.LocalDate class is an immutable datetime class representing a date without a time zone. LocalDate is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

This is the way I would do it and it should be

@app.route('/api/add_message/<uuid>', methods=['GET', 'POST'])
def add_message(uuid):
    content = request.get_json(silent=True)
    # print(content) # Do your processing
    return uuid

With silent=True set, the get_json function will fail silently when trying to retrieve the json body. By default this is set to False. If you are always expecting a json body (not optionally), leave it as silent=False.

Setting force=True will ignore the request.headers.get('Content-Type') == 'application/json' check that flask does for you. By default this is also set to False.

See flask documentation.

I would strongly recommend leaving force=False and make the client send the Content-Type header to make it more explicit.

Hope this helps!

As noted elsewhere, you can use join.

If you are using commands as inputs (as I was), use the following syntax:

-join($(Command1), "," , $(Command2))

This would result in the two outputs separated by a comma.

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

If all you want to do is run your main class (without compiling the .java files on which the main class doesn't depend), then you can do the following:

cd <root-package-directory>
javac <complete-path-to-main-class>

or

javac -cp <root-package-directory> <complete-path-to-main-class>

javac would automatically resolve all the dependencies and compile all the dependencies as well.

For MySql take in mind that it's not a good idea to write camelcase. For example if the schema is like that:

CREATE TABLE IF NOT EXISTS `task`(
    `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
    `teaching_hours` DECIMAL(5,2) DEFAULT NULL,
    `isActive` BOOLEAN DEFAULT FALSE,
    `is_validated` BOOLEAN DEFAULT FALSE,
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

You must be very careful cause isActive column will translate to isactive. So in your Entity class is should be like this:

 @Basic
 @Column(name = "isactive", nullable = true)
 public boolean isActive() {
     return isActive;
 }
 public void setActive(boolean active) {
     isActive = active;
 }

That was my problem at least that got me your error

This has nothing to do with MySql which is case insensitive, but rather is a naming strategy that spring will use to translate your tables. For more refer to this post

the simple and easy way to do that is use on event:

$('body').on('click','#element',function(){
    //somthing
});

but we can say this is not the best way to do this. I suggest a another way to do this is use clone() method instead of using dynamic html. Write some html in you file for example:

<div id='div1'></div>

Now in the script tag make a clone of this div then all the properties of this div would follow with new element too. For Example:

var dynamicDiv = jQuery('#div1').clone(true);

Now use the element dynamicDiv wherever you want to add it or change its properties as you like. Now all jQuery functions will work with this element

This is how I configure it on my server:

0  19  *  *  1,3,5 root bash /home/divo/data/support_files/support_files_inc_backup.sh

The above command will run my script at 19:00 on Monday, Wednesday, and Friday.

NB: For cron entries for day of the week (dow)

0 = Sunday
1 = Monday
2 = Tuesday
3 = Wednesday
4 = Thursday
5 = Friday
6 = Saturday

you could also use tig for a nice, ncurses-based git repository browser. To view history of a file:

tig path/to/file

from IPython.display import display
display(df)  # OR
print df.to_html()

Solution for MySQL Workbench 6.3E

• On left panel, right click your table and selecct "Table Inspector"
• On center panel, click DDL label

In oracle an empty varchar2 and null are treated the same, and your observations show that.

when you write:

select * from table where a = '';

its the same as writing

select * from table where a = null;

and not a is null

which will never equate to true, so never return a row. same on the insert, a NOT NULL means you cant insert a null or an empty string (which is treated as a null)

This was the top result when googling "cannot open source file" so I figured I would share what my issue was since I had already included the correct path.

I'm not sure about other IDEs or compilers, but least for Visual Studio, make sure there isn't a space in your list of include directories. I had put a space between the ; of the last entry and the beginning of my new entry which then caused Visual Studio to disregard my inclusion.
