Change port number for Xampp Go to the file C:\xampp\apache\conf\httpd.conf

#Listen 12.34.56.78:80
Listen 80

Change 80 to 82

as

#Listen 12.34.56.78:82
Listen 82

now your url will be

http://localhost:82

Zip files have a table of contents. Every zip utility should have the ability to query just the TOC. Or you can use a command line program like 7zip -t to print the table of contents and redirect it to a text file.

You can significantly speed up Git on Windows by running three commands to set some config options:

git config --global core.preloadindex true
git config --global core.fscache true
git config --global gc.auto 256

Notes:

• core.preloadindex does filesystem operations in parallel to hide latency (update: enabled by default in Git 2.1)

• core.fscache fixes UAC issues so you don't need to run Git as administrator (update: enabled by default in Git for Windows 2.8)

• gc.auto minimizes the number of files in .git/

As was mentioned in an older version (2009) of the "Tree Conflict" design document:

XFAIL conflict from merge of add over versioned file

This test does a merge which brings a file addition without history onto an existing versioned file.
This should be a tree conflict on the file of the 'local obstruction, incoming add upon merge' variety. Fixed expectations in r35341.

(This is also called "evil twins" in ClearCase by the way):
a file is created twice (here "added" twice) in two different branches, creating two different histories for two different elements, but with the same name.

The theoretical solution is to manually merge those files (with an external diff tool) in the destination branch 'B2'.

If you still are working on the source branch, the ideal scenario would be to remove that file from the source branch B1, merge back from B2 to B1 in order to make that file visible on B1 (you will then work on the same element).
If a merge back is not possible because merges only occurs from B1 to B2, then a manual merge will be necessary for each B1->B2 merges.

About the .dex File :

One of the most remarkable features of the Dalvik Virtual Machine (the workhorse under the Android system) is that it does not use Java bytecode. Instead, a homegrown format called DEX was introduced and not even the bytecode instructions are the same as Java bytecode instructions.

Compiled Android application code file.

Android programs are compiled into .dex (Dalvik Executable) files, which are in turn zipped into a single .apk file on the device. .dex files can be created by automatically translating compiled applications written in the Java programming language.

Dex file format:

 1. File Header
 2. String Table
 3. Class List
 4. Field Table
 5. Method Table
 6. Class Definition Table
 7. Field List
 8. Method List
 9. Code Header
10. Local Variable List

Android has documentation on the Dalvik Executable Format (.dex files). You can find out more over at the official docs: Dex File Format

.dex files are similar to java class files, but they were run under the Dalkvik Virtual Machine (DVM) on older Android versions, and compiled at install time on the device to native code with ART on newer Android versions.

You can decompile .dex using the dexdump tool which is provided in android-sdk.

There are also some Reverse Engineering Techniques to make a jar file or java class file from a .dex file.

Or see cut_number from the ggplot2 package, e.g.

das$wt_2 <- as.numeric(cut_number(das$wt,3))

Note that cut(...,3) divides the range of the original data into three ranges of equal lengths; it doesn't necessarily result in the same number of observations per group if the data are unevenly distributed (you can replicate what cut_number does by using quantile appropriately, but it's a nice convenience function). On the other hand, Hmisc::cut2() using the g= argument does split by quantiles, so is more or less equivalent to ggplot2::cut_number. I might have thought that something like cut_number would have made its way into dplyr by so far, but as far as I can tell it hasn't.

I had this issue, I was scratching my head for the best part of two days.

Turns out I completely forgot I had CloudFlare setup on the domain I was live testing on.

CloudFlare caches your JavaScript and CSS. Turned on development mode and BAM!

Seriously... two whole days.

I am assuming (please correct me if I am wrong) that you want to re-display the edit page if the edit fails and to do this you are using a redirect.

You may have more luck by just returning the view again rather than trying to redirect the user, this way you will be able to use the ModelState to output any errors too.

Edit:

Updated based on feedback. You can place the previous URL in the viewModel, add it to a hidden field then use it again in the action that saves the edits.

For instance:

public ActionResult Index()
{
    return View();
}

[HttpGet] // This isn't required
public ActionResult Edit(int id)
{
   // load object and return in view
   ViewModel viewModel = Load(id);

   // get the previous url and store it with view model
   viewModel.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;

   return View(viewModel);
}

[HttpPost]
public ActionResult Edit(ViewModel viewModel)
{
   // Attempt to save the posted object if it works, return index if not return the Edit view again

   bool success = Save(viewModel);
   if (success)
   {
       return Redirect(viewModel.PreviousUrl);
   }
   else
   {
      ModelState.AddModelError("There was an error");
      return View(viewModel);
   }
}

The BeginForm method for your view doesn't need to use this return URL either, you should be able to get away with:

@model ViewModel

@using (Html.BeginForm())
{
    ...
    <input type="hidden" name="PreviousUrl" value="@Model.PreviousUrl" />
}

Going back to your form action posting to an incorrect URL, this is because you are passing a URL as the 'id' parameter, so the routing automatically formats your URL with the return path.

This won't work because your form will be posting to an controller action that won't know how to save the edits. You need to post to your save action first, then handle the redirect within it.

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.

...

One more cause for the "secret key not available" message: GPG version mismatch.

Practical example: I had been using GPG v1.4. Switching packaging systems, the MacPorts supplied gpg was removed, and revealed another gpg binary in the path, this one version 2.0. For decryption, it was unable to locate the secret key and gave this very error. For encryption, it complained about an unusable public key. However, gpg -k and -K both listed valid keys, which was the cause of major confusion.

Here's the simplest solution with a clear selector:

function select_option(i) {
  return $('span#span_id select option[value="' + i + '"]').html();
}

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "file/to/transfer";

    Session session = null;
    Channel channel = null;
    ChannelSftp channelSftp = null;
    System.out.println("preparing the host information for sftp.");

    try {
        JSch jsch = new JSch();
        session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
        session.setPassword(SFTPPASS);
        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        System.out.println("Host connected.");
        channel = session.openChannel("sftp");
        channel.connect();
        System.out.println("sftp channel opened and connected.");
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd(SFTPWORKINGDIR);
        File f = new File(fileName);
        channelSftp.put(new FileInputStream(f), f.getName());
        log.info("File transfered successfully to host.");
    } catch (Exception ex) {
        System.out.println("Exception found while tranfer the response.");
    } finally {
        channelSftp.exit();
        System.out.println("sftp Channel exited.");
        channel.disconnect();
        System.out.println("Channel disconnected.");
        session.disconnect();
        System.out.println("Host Session disconnected.");
    }
}   

I don't know if this will be of any help to you, but I have written a couple of articles which introduce the basics.

• HtmlAgilityPack Article Series
• Introduction To The HtmlAgilityPack Library
• Easily extracting links from a snippet of html with HtmlAgilityPack

The next article is 95% complete, I just have to write up explanations of the last few parts of the code I have written. If you are interested then I will try to remember to post here when I publish it.

Password changes are handled by the subversion server administrator. As a user there is no password change option.

Check with your server admin.

If you are the admin, find your SVN Server installation. If you don't know where it is, it could be listed in Start->Programs, running under services in Start->Control Panel->Services or it could be listed under C:\Program Files.

The SVN Server should have an application to run to add/change/delete authentication and users.

If you want to use valueChangeListener, you need to submit the form every time a new option is chosen. Something like this:

<p:selectOneMenu value="#{mymb.employee}" onchange="submit()"
                 valueChangeListener="#{mymb.handleChange}" >
    <f:selectItems value="#{mymb.employeesList}" var="emp"
                   itemLabel="#{emp.employeeName}" itemValue="#{emp.employeeID}" />
</p:selectOneMenu>

public void handleChange(ValueChangeEvent event){  
    System.out.println("New value: " + event.getNewValue());
}

Or else, if you want to use <p:ajax>, it should look like this:

<p:selectOneMenu value="#{mymb.employee}" >
    <p:ajax listener="#{mymb.handleChange}" />
    <f:selectItems value="#{mymb.employeesList}" var="emp"
                   itemLabel="#{emp.employeeName}" itemValue="#{emp.employeeID}" />
</p:selectOneMenu>

private String employeeID;

public void handleChange(){  
    System.out.println("New value: " + employee);
}

One thing to note is that in your example code, I saw that the value attribute of your <p:selectOneMenu> is #{mymb.employeesList} which is the same as the value of <f:selectItems>. The value of your <p:selectOneMenu> should be similar to my examples above which point to a single employee, not a list of employees.

You need to make sure the IIS Management Console is installed.

In my case for avoiding that problem:

1. Be sure that you are dealing with Xcode 7, NOT lower versions. In lower version this flag does not exist.

2. Setup: Project>Build Settings>All>Build Options>Enable Bitcode = NO

tag is a block-level element but tag is inline element.Normally we use span tag to style inside block elements.but you don't need to use span tag to inline style.you have to do is; convert block element to inline element using "display: inline"

If you are seeing only part of your request payload, you need to call the setMaxPayloadLength function as it defaults to showing only 50 characters in your request body. Also, setting setIncludeHeaders to false is a good idea if you don't want to log your auth headers!

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
    CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
    loggingFilter.setIncludeClientInfo(false);
    loggingFilter.setIncludeQueryString(false);
    loggingFilter.setIncludePayload(true);
    loggingFilter.setIncludeHeaders(false);
    loggingFilter.setMaxPayloadLength(500);
    return loggingFilter;
}

I built a general method for that with following features:

• returning "not modified" if the file hasn't been modified locally, a Status.NOT_MODIFIED is sent to the caller. Uses Apache Commons Lang
• using a file stream object instead of reading the file itself

Here the code:

import org.apache.commons.lang3.time.DateUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

private static final Logger logger = LoggerFactory.getLogger(Utils.class);

@GET
@Path("16x16")
@Produces("image/png")
public Response get16x16PNG(@HeaderParam("If-Modified-Since") String modified) {
    File repositoryFile = new File("c:/temp/myfile.png");
    return returnFile(repositoryFile, modified);
}

/**
 * 
 * Sends the file if modified and "not modified" if not modified
 * future work may put each file with a unique id in a separate folder in tomcat
 *   * use that static URL for each file
 *   * if file is modified, URL of file changes
 *   * -> client always fetches correct file 
 * 
 *     method header for calling method public Response getXY(@HeaderParam("If-Modified-Since") String modified) {
 * 
 * @param file to send
 * @param modified - HeaderField "If-Modified-Since" - may be "null"
 * @return Response to be sent to the client
 */
public static Response returnFile(File file, String modified) {
    if (!file.exists()) {
        return Response.status(Status.NOT_FOUND).build();
    }

    // do we really need to send the file or can send "not modified"?
    if (modified != null) {
        Date modifiedDate = null;

        // we have to switch the locale to ENGLISH as parseDate parses in the default locale
        Locale old = Locale.getDefault();
        Locale.setDefault(Locale.ENGLISH);
        try {
            modifiedDate = DateUtils.parseDate(modified, org.apache.http.impl.cookie.DateUtils.DEFAULT_PATTERNS);
        } catch (ParseException e) {
            logger.error(e.getMessage(), e);
        }
        Locale.setDefault(old);

        if (modifiedDate != null) {
            // modifiedDate does not carry milliseconds, but fileDate does
            // therefore we have to do a range-based comparison
            // 1000 milliseconds = 1 second
            if (file.lastModified()-modifiedDate.getTime() < DateUtils.MILLIS_PER_SECOND) {
                return Response.status(Status.NOT_MODIFIED).build();
            }
        }
    }        
    // we really need to send the file

    try {
        Date fileDate = new Date(file.lastModified());
        return Response.ok(new FileInputStream(file)).lastModified(fileDate).build();
    } catch (FileNotFoundException e) {
        return Response.status(Status.NOT_FOUND).build();
    }
}

Note that the Locale switching does not seem to be thread-safe. I think, it's better to switch the locale globally. I am not sure about the side-effects though...

Another solution I haven't seen mentioned is to use pseudo elements and I do believe this solution will work with any CSS 2.1 compliant browser (= IE8,= Safari 2, ...) and it should also be responsive :

element::after
{
content:' ';
position:relative;
display:block;
width:100%;
height:100%;
bottom:0;
right:-5px; /* 10 px from the right of element inner-margin (padding) see example */
background:url() right center no-repeat;
}

Example: The element eg. a square sized 100px (without considering borders) has a 10px padding and a background image should be shown inside the right padding. This means the pseudo-element is a 80px sized square. We want to stick it to the right border of the element with right:-10px;. If we'd like to have the background-image 5px away from the right border we need to stick the pseudo-element 5px away from the right border of the element with right:-5px;... Test it for your self here : http://jsfiddle.net/yHucT/

def valid = pointAddress.findAll { a ->
    validPointTypes.any { a.contains(it) }
}

Should do it

                     this.Visible = false;
                        //or                         // will make LOgin Form invisivble
                        //this.Enabled = false;
                         //  or
                       // this.Hide(); 



                        Form1 form1 = new Form1();
                        form1.ShowDialog();

                        this.Dispose();

$headers = array(
    'Authorization: Basic '. base64_encode($username.':'.$password),
);
...
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

BigDecimal does not seem to respect Locale settings.

Locale.getDefault(); //returns sl_SI

Slovenian locale should have a decimal comma. Guess I had strange misconceptions regarding numbers.

a = new BigDecimal("1,2") //throws exception
a = new BigDecimal("1.2") //is ok

a.toPlainString() // returns "1.2" always

I have edited a part of my message that made no sense since it proved to be due the human error (forgot to commit data and was looking at the wrong thing).

Same as BigDecimal can be said for any Java .toString() functions. I guess that is good in some ways. Serialization for example or debugging. There is an unique string representation.

Also as others mentioned using formatters works OK. Just use formatters, same for the JSF frontend, formatters do the job properly and are aware of the locale.

int sum = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
    sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);
}
label1.Text = sum.ToString();

WordPress include tags, categories and taxonomies in search results

This code is taken from http://atiblog.com/custom-search-results/

Some functions here are taken from twentynineteen theme.Because it is made on this theme.

This code example will help you to include tags, categories or any custom taxonomy in your search. And show the posts contaning these tags or categories.

You need to modify your search.php of your theme to do so.

<?php
$search=get_search_query();
$all_categories = get_terms( array('taxonomy' => 'category','hide_empty' => true) ); 
$all_tags = get_terms( array('taxonomy' => 'post_tag','hide_empty' => true) );
//if you have any custom taxonomy
$all_custom_taxonomy = get_terms( array('taxonomy' => 'your-taxonomy-slug','hide_empty' => true) );

$mcat=array();
$mtag=array();
$mcustom_taxonomy=array();

foreach($all_categories as $all){
$par=$all->name;
if (strpos($par, $search) !== false) {
array_push($mcat,$all->term_id);
}
}

foreach($all_tags as $all){
$par=$all->name;
if (strpos($par, $search) !== false) {
array_push($mtag,$all->term_id);
}
}

foreach($all_custom_taxonomy as $all){
$par=$all->name;
if (strpos($par, $search) !== false) {
array_push($mcustom_taxonomy,$all->term_id);
}
}

$matched_posts=array();
$args1= array( 'post_status' => 'publish','posts_per_page' => -1,'tax_query' =>array('relation' => 'OR',array('taxonomy' => 'category','field' => 'term_id','terms' =>$mcat),array('taxonomy' => 'post_tag','field' => 'term_id','terms' =>$mtag),array('taxonomy' => 'custom_taxonomy','field' => 'term_id','terms' =>$mcustom_taxonomy)));

$the_query = new WP_Query( $args1 );
if ( $the_query->have_posts() ) {
while ( $the_query->have_posts() ) {
$the_query->the_post();
array_push($matched_posts,get_the_id());
//echo '<li>' . get_the_id() . '</li>';
}
wp_reset_postdata();
} else {

}

?>
<?php
// now we will do the normal wordpress search
$query2 = new WP_Query( array( 's' => $search,'posts_per_page' => -1 ) );
if ( $query2->have_posts() ) {
while ( $query2->have_posts() ) {
$query2->the_post();
array_push($matched_posts,get_the_id());
}
wp_reset_postdata();
} else {

}
$matched_posts= array_unique($matched_posts);
$matched_posts=array_values(array_filter($matched_posts));
//print_r($matched_posts);

<?php
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$query3 = new WP_Query( array( 'post_type'=>'any','post__in' => $matched_posts ,'paged' => $paged) );
if ( $query3->have_posts() ) {

get_template_part( 'template-parts/content/content', 'excerpt' );
}
twentynineteen_the_posts_navigation();
wp_reset_postdata();
} else {

}
?>

dropdowns always show up on top, only solution for this problem is to hide dropdowns when image is displayed (display:block or visibility:visibile) and show them when image hidden (display:none or visibility:hidden)

Supplemental answer

Here is how the standard keyboard behaves for each of these input types.

See this answer for more details.

Coffeescript for Patrick's popular answer above:

Number::formatMoney = (decimalPlaces, decimalChar, thousandsChar) ->  
  n = this  
  c = decimalPlaces  
  d = decimalChar  
  t = thousandsChar  
  c = (if isNaN(c = Math.abs(c)) then 2 else c)  
  d = (if d is undefined then "." else d)  
  t = (if t is undefined then "," else t)  
  s = (if n < 0 then "-" else "")  
  i = parseInt(n = Math.abs(+n or 0).toFixed(c)) + ""  
  j = (if (j = i.length) > 3 then j % 3 else 0)  
  s + (if j then i.substr(0, j) + t else "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (if c then d + Math.abs(n - i).toFixed(c).slice(2) else "")  

In order to change the data source from the ribbon in excel 2007...

Click on your pivot table in the worksheet. Go to the ribbon where it says Pivot Table Tools, Options Tab. Select the Change Data Source button. A dialog box will appear.

To get the right range and avoid an error message... select the contents of the existing field and delete it, then switch to the new data source worksheet and highlight the data area (the dialog box will stay on top of all windows). Once you've selected the new data source correctly, it will fill in the blank field (which you deleted before) in the dialog box. Click OK. Switch back to your pivot table and it should have updated with the new data from the new source.

DateTime.Now.ToString("dd/MM/yyyy");

For me, the most flexible way to run PowerShell script from C# was using PowerShell.Create().AddScript()

The snippet of the code is

string scriptDirectory = Path.GetDirectoryName(
    ConfigurationManager.AppSettings["PathToTechOpsTooling"]);

var script =    
    "Set-Location " + scriptDirectory + Environment.NewLine +
    "Import-Module .\\script.psd1" + Environment.NewLine +
    "$data = Import-Csv -Path " + tempCsvFile + " -Encoding UTF8" + 
        Environment.NewLine +
    "New-Registration -server " + dbServer + " -DBName " + dbName + 
       " -Username \"" + user.Username + "\" + -Users $userData";

_powershell = PowerShell.Create().AddScript(script);
_powershell.Invoke<User>();
foreach (var errorRecord in _powershell.Streams.Error)
    Console.WriteLine(errorRecord);

You can check if there's any error by checking Streams.Error. It was really handy to check the collection. User is the type of object the PowerShell script returns.

Simple alert with array data:

NSString *name = [[YourArray objectAtIndex:indexPath.row ]valueForKey:@"Name"];

NSString *msg = [[YourArray objectAtIndex:indexPath.row ]valueForKey:@"message"];

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:name
                                                message:msg
                                               delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];
[alert show];

grep -v is your friend:

grep --help | grep invert  

-v, --invert-match select non-matching lines

Also check out the related -L (the complement of -l).

-L, --files-without-match only print FILE names containing no match

1. Upload setup.py to drive.
2. Mount the drive.
3. Get the path of setup.py.
4. !python PATH install.

Take the terminal and type

fuser 8081/tcp

You will get a Process id which is using port 8081 Now kill the process

kill <pid>

Somewhere, you need to tell Apache that people are allowed to see contents of this directory.

<Directory "F:/bar/public">
    Order Allow,Deny
    Allow from All
    # Any other directory-specific stuff
</Directory>

More info

For anybody reading this in 2019, after React 16.8 was released, take a look at the React Hooks. It really simplifies handling states in components. The docs are very well written with an example of exactly what you need.

We faced the same problem:

ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error error opening file /fs01/app/rms01/external/logs/SH_EXT_TAB_VGAG_DELIV_SCHED.log

In our case we had a RAC with 2 nodes. After giving write permission on the log directory, on both sides, everything worked fine.

Lambda explained for everyone:

Lambda is an annonymous function. This means lambda is a function objekt in Python that doesnt require a reference before. Let's concider this bit of code here:

def name_of_func():
    #command/instruction
    print('hello')

print(type(name_of_func))   #the name of the function is a reference
                            #the reference contains a function Objekt with command/instruction

To proof my proposition I print out the type of name_of_func which returns us:

<class 'function'>

A function must have a interface, but a interface dosent needs to contain something. What does this mean? Let's look a little bit closer to our function and we may notice that out of the name of the functions there are some more details we need to explain to understand what a function is.

A regular function will be defined with the syntax "def", then we type in the name and settle the interface with "()" and ending our definition by the syntax ":". Now we enter the functions body with our instructions/commands.

So let's consider this bit of code here:

def print_my_argument(x):
    print(x)


print_my_argument('Hello')

In this case we run our function, named "print_my_argument" and passing a parameter/argument through the interface. The Output will be:

Hello

So now that we know what a function is and how the architecture works for a function, we can take a look to an annonymous function. Let's consicder this bit of code here:

def name_of_func():
    print('Hello')



lambda: print('Hello')

these function objekts are pretty much the same except of the fact that the upper, regular function have a name and the other function is an annonymous one. Let's take a closer look on our annonymous function, to understand how to use it.

So let's concider this bit of code here:

def delete_last_char(arg1=None):
    print(arg1[:-1])

string = 'Hello World'
delete_last_char(string)

f = lambda arg1=None: print(arg1[:-1])
f(string)

So what we have done in the above code is to write once againg, a regular function and an anonymous function. Our anonymous function we had assignd to a var, which is pretty much the same as to give this function a name. Anyway, the output will be:

Hello Worl
Hello Worl

To fully proof that lambda is a function object and doesnt just mimik a function we run this bit of code here:

string = 'Hello World'
f = lambda arg1=string: print(arg1[:-1])
f()
print(type(f))

and the Output will be:

Hello Worl
<class 'function'>

Last but not least you should know that every function in python needs to return something. If nothing is defined in the body of the function, None will be returned by default. look at this bit of code here:

def delete_last_char(arg1):
    print(arg1[:-1])

string = 'Hello World'
x = delete_last_char(string)

f = lambda arg1=string: print(arg1[:-1])
x2 = f()

print(x)
print(x2)

Output will be:

Hello Worl
Hello Worl
None
None

I found another relatively easy solution for your question.

As you can see from the FragmentPagerAdapter source code, the fragments managed by FragmentPagerAdapter store in the FragmentManager under the tag generated using:

String tag="android:switcher:" + viewId + ":" + index;

The viewId is the container.getId(), the container is your ViewPager instance. The index is the position of the fragment. Hence you can save the object id to the outState:

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("viewpagerid" , mViewPager.getId() );
}

@Override
    protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_main);
    if (savedInstanceState != null)
        viewpagerid=savedInstanceState.getInt("viewpagerid", -1 );  

    MyFragmentPagerAdapter titleAdapter = new MyFragmentPagerAdapter (getSupportFragmentManager() , this);        
    mViewPager = (ViewPager) findViewById(R.id.pager);
    if (viewpagerid != -1 ){
        mViewPager.setId(viewpagerid);
    }else{
        viewpagerid=mViewPager.getId();
    }
    mViewPager.setAdapter(titleAdapter);

If you want to communicate with this fragment, you can get if from FragmentManager, such as:

getSupportFragmentManager().findFragmentByTag("android:switcher:" + viewpagerid + ":0")

For me, the problem was that I used:

List<Some> someCollection ...;
_dbContext.Remove(someCollection);

instead of:

_dbContext.RemoveRange(someCollection);

With Eloquent its very easy to retrieve relational data. Checkout the following example with your scenario in Laravel 5.

We have three models:

1) Article (belongs to user and category)

2) Category (has many articles)

3) User (has many articles)

1) Article.php

<?php

namespace App\Models;
 use Eloquent;

class Article extends Eloquent{

    protected $table = 'articles';

    public function user()
    {
        return $this->belongsTo('App\Models\User');
    }

    public function category()
    {
        return $this->belongsTo('App\Models\Category');
    }

}

2) Category.php

<?php

namespace App\Models;

use Eloquent;

class Category extends Eloquent
{
    protected $table = "categories";

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

3) User.php

<?php

namespace App\Models;
use Eloquent;

class User extends Eloquent
{
    protected $table = 'users';

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

You need to understand your database relation and setup in models. User has many articles. Category has many articles. Articles belong to user and category. Once you setup the relationships in Laravel, it becomes easy to retrieve the related information.

For example, if you want to retrieve an article by using the user and category, you would need to write:

$article = \App\Models\Article::with(['user','category'])->first();

and you can use this like so:

//retrieve user name 
$article->user->user_name  

//retrieve category name 
$article->category->category_name

In another case, you might need to retrieve all the articles within a category, or retrieve all of a specific user`s articles. You can write it like this:

$categories = \App\Models\Category::with('articles')->get();

$users = \App\Models\Category::with('users')->get();

I'm able to get the Class of the generic type this way:

class MyList<T> {
  Class<T> clazz = (Class<T>) DAOUtil.getTypeArguments(MyList.class, this.getClass()).get(0);
}

You need two functions from this file: http://code.google.com/p/hibernate-generic-dao/source/browse/trunk/dao/src/main/java/com/googlecode/genericdao/dao/DAOUtil.java

I can't extract hours, with HOUR(Date())

There is a way to call HOUR (I would not recommend to use it though because there is DATEPART function) using ODBC Scalar Functions:

SELECT {fn HOUR(GETDATE())} AS hour

Technically, the Integrity attribute helps with just that - it enables the proper verification of the data source. That is, it merely allows the browser to verify the numbers in the right source file with the amounts requested by the source file located on the CDN server.

Going a bit deeper, in case of the established encrypted hash value of this source and its checked compliance with a predefined value in the browser - the code executes, and the user request is successfully processed.

Crossorigin attribute helps developers optimize the rates of CDN performance, at the same time, protecting the website code from malicious scripts.

In particular, Crossorigin downloads the program code of the site in anonymous mode, without downloading cookies or performing the authentication procedure. This way, it prevents the leak of user data when you first load the site on a specific CDN server, which network fraudsters can easily replace addresses.

I do not know of a standalone PHP / Apache solution, as this would require a PHP library that can read and render SVG images. I'm not sure such a library exists - I don't know any.

ImageMagick is able to rasterize SVG files, either through the command line or the PHP binding, IMagick, but seems to have a number of quirks and external dependencies as shown e.g. in this forum thread. I think it's still the most promising way to go, it's the first thing I would look into if I were you.

You can run simple commands like

curl ifconfig.co

curl ifconfig.me

wget -qO - icanhazip.com

The solution of this problem is really very simple. actually Google start using a new authorization mechanism for its User.. you might have seen another line in debug console prompting you to log into your account using any browser.! this is because of new XOAUTH2 authentication mechanism which google start using since 2014. remember.. do not use the ssl over port 465, instead go for tls over 587. this is just because of XOAUTH2 authentication mechanism. if you use ssl over 465, your request will be bounced back.

what you really need to do is .. log into your google account and open up following address https://www.google.com/settings/security/lesssecureapps and check turn on . you have to do this for letting you to connect with the google SMTP because according to new authentication mechanism google bounce back all the requests from all those applications which does not follow any standard encryption technique.. after checking turn on.. you are good to go.. here is the code which worked fine for me..

require_once 'C:\xampp\htdocs\email\vendor\autoload.php';

define ('GUSER','[email protected]');
define ('GPWD','your password');


// make a separate file and include this file in that. call this function in that file.

function smtpmailer($to, $from, $from_name, $subject, $body) { 
    global $error;
    $mail = new PHPMailer();  // create a new object
    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 2;  // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true;  // authentication enabled
    $mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
    $mail->SMTPAutoTLS = false;
    $mail->Host = 'smtp.gmail.com';
    $mail->Port = 587;

    $mail->Username = GUSER;  
    $mail->Password = GPWD;           
    $mail->SetFrom($from, $from_name);
    $mail->Subject = $subject;
    $mail->Body = $body;
    $mail->AddAddress($to);
    if(!$mail->Send()) {
        $error = 'Mail error: '.$mail->ErrorInfo; 
        return false;
    } else {
        $error = 'Message sent!';
        return true;

It's a C heritage, in C, if you do :

enum TokenType
{
    blah1   = 0x00000000,
    blah2   = 0X01000000,
    blah3   = 0X02000000
};

you'll have to use it doing something like :

enum TokenType foo;

But if you do this :

typedef enum e_TokenType
{
    blah1   = 0x00000000,
    blah2   = 0X01000000,
    blah3   = 0X02000000
} TokenType;

You'll be able to declare :

TokenType foo;

But in C++, you can use only the former definition and use it as if it were in a C typedef.

I had to include -lmysqlcppconn to my build in order to get it to work.

hmm. why don't you use onClick()

<select id="mySelect" onChange="enable();">
   <option onClick="disable();">No</option>
   <option onClick="enable();">Yes</option>
</select>

Though this is a very old question, I thought it would be nice to update it with recent information;

Since jQuery 1.8 there is a jQuery.parseHTML() function which is now a preferred way of creating elements. Also, there are some issues with parsing HTML via $('(html code goes here)'), fo example official jQuery website mentions the following in one of their release notes:

Relaxed HTML parsing: You can once again have leading spaces or newlines before tags in $(htmlString). We still strongly advise that you use $.parseHTML() when parsing HTML obtained from external sources, and may be making further changes to HTML parsing in the future.

To relate to the actual question, provided example could be translated to:

this.$OuterDiv = $($.parseHTML('<div></div>'))
    .hide()
    .append($($.parseHTML('<table></table>'))
        .attr({ cellSpacing : 0 })
        .addClass("text")
    )
;

which is unfortunately less convenient than using just $(), but it gives you more control, for example you may choose to exclude script tags (it will leave inline scripts like onclick though):

> $.parseHTML('<div onclick="a"></div><script></script>')
[<div onclick=?"a">?</div>?]

> $.parseHTML('<div onclick="a"></div><script></script>', document, true)
[<div onclick=?"a">?</div>?, <script>?</script>?]

Also, here's a benchmark from the top answer adjusted to the new reality:

JSbin Link

jQuery 1.9.1

  $.parseHTML:    88ms
  $($.parseHTML): 240ms
  <div></div>:    138ms
  <div>:          143ms
  createElement:  64ms

It looks like parseHTML is much closer to createElement than $(), but all the boost is gone after wrapping the results in a new jQuery object

If you just want to check if the file uploaded is an image you can just try to load it into <img> tag an check for any error callback.

Example:

var input = document.getElementsByTagName('input')[0];
var reader = new FileReader();

reader.onload = function (e) {
    imageExists(e.target.result, function(exists){
        if (exists) {

            // Do something with the image file.. 

        } else {

            // different file format

        }
    });
};

reader.readAsDataURL(input.files[0]);


function imageExists(url, callback) {
    var img = new Image();
    img.onload = function() { callback(true); };
    img.onerror = function() { callback(false); };
    img.src = url;
}

A correct answer has already been supplied, but for you to learn how to help yourself I thought I'd throw in something helpful in a different way; if you can sum up what you're trying to achieve in one word, there's a mighty fine help feature on Linux.

man -k <your search term>

What that does is to list all commands that have your search term in the short description. There's usually a pretty good chance that you will find what you're after. ;)

That output can sometimes be somewhat overwhelming, and I'd recommend narrowing it down to the executables, rather than all available man-pages, like so:

man -k find | egrep '\(1\)'

or, if you also want to look for commands that require higher privilege levels, like this:

man -k find | egrep '\([18]\)'

Xcode 4.6 will prompt you to reinstall any older versions of the iOS Simulator if you just delete the SDK. To avoid that, you must also delete the Xcode cache. Then you won't be forced to reinstall the older SDK on launch.

To remove the iOS 5.0 simulator, delete these and then restart Xcode:

1. /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/PhoneSimulator5.0.sdk
2. ~/Library/Caches/com.apple.dt.Xcode

For example, after doing a clean install of Xcode, I installed the iOS 5.0 simulator from Xcode preferences. Later, I decided that 5.1 was enough but couldn't remove the 5.0 version. Xcode kept forcing me to reinstall it on launch. After removing both the cache file and the SDK, it no longer asked.

Your performance problems are more likely to be because of the number of joins you are doing and whether the columns you are joining on have indexes or not.

Worst case you could easily be doing 9 whole table scans for each join.

Dim MyString As String = "Hello World"
Dim YourString As String = "Hello World"
Console.WriteLine(String.Equals(MyString, YourString))

returns a bool True. This comparison is case-sensitive.

So in your example,

if String.Equals(string1, string2) and String.Equals(string3, string4) then
  ' do something
else
  ' do something else
end if

Go to app/config/app.php

and set 'debug' => true,

In my case, I used the ssl module to "workaround" the certification like so:

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

Then to read your link content, you can use:

urllib.request.urlopen(urllink)

They are simply showed like this:

_______________________
|   <<enumeration>>   |
|    DaysOfTheWeek    |
|_____________________|
| Sunday              |
| Monday              |
| Tuesday             |
| ...                 |
|_____________________|

And then just have an association between that and your class.

In SQL Server 2008 you can use

http://www.sommarskog.se/share_data.html#tableparam

or else simple and same as common execution

CREATE PROCEDURE OrderSummary @MaxQuantity INT OUTPUT AS

SELECT Ord.EmployeeID, SummSales = SUM(OrDet.UnitPrice * OrDet.Quantity)
FROM Orders AS Ord
     JOIN [Order Details] AS OrDet ON (Ord.OrderID = OrDet.OrderID)
GROUP BY Ord.EmployeeID
ORDER BY Ord.EmployeeID

SELECT @MaxQuantity = MAX(Quantity) FROM [Order Details]

RETURN (SELECT SUM(Quantity) FROM [Order Details])
GO

I hopes its help to you

for simple Scroll, use following style

height: 200px; overflow: scroll;

and use this style class which div or section you want to show scroll

Here is some code that as far as I can best tell does the same thing as the accepted answer but with less code:

    public static bool IsFileLocked(string file)
    {
        try
        {
            using (var stream = File.OpenRead(file))
                return false;
        }
        catch (IOException)
        {
            return true;
        }        
    }

However I think it is more robust to do it in the following manner:

    public static void TryToDoWithFileStream(string file, Action<FileStream> action, 
        int count, int msecTimeOut)
    {
        FileStream stream = null;
        for (var i = 0; i < count; ++i)
        {
            try
            {
                stream = File.OpenRead(file);
                break;
            }
            catch (IOException)
            {
                Thread.Sleep(msecTimeOut);
            }
        }
        action(stream);
    }

First thing, you don't need to write

ResultSet rs = stmt.executeQuery(sql);

just write

ResultSet rs = stmt.executeQuery();

The above mentioned syntax is used for Statements not for PreparedStatement.

Second thing, rs.next() checks if the result set contains any values or not. It returns a boolean value as well as it moves the cursor to the first value in the result set because initially it is at BEFORE FIRST Position. So if you want to access first value in result set, you need to write rs.next().

The other answers may work for you, but they did not cover my case. I wanted some XML to be validated, and others not. This image shows how to exclude certain folders (or files) for XML validation.

Ok for all of you out there that arrived here in desperation searching for the same problem. I hope you will find this quicker then I did ;O.

This is how it is solved. JoostK told me at github that "the first argument to join is the table (or data) you're joining.". And he was right.

Here is the code. Different table and names but you will get the idea right? It t

DB::table('users')
        ->select('first_name', 'TotalCatches.*')

        ->join(DB::raw('(SELECT user_id, COUNT(user_id) TotalCatch,
               DATEDIFF(NOW(), MIN(created_at)) Days,
               COUNT(user_id)/DATEDIFF(NOW(), MIN(created_at))
               CatchesPerDay FROM `catch-text` GROUP BY user_id)
               TotalCatches'), 
        function($join)
        {
           $join->on('users.id', '=', 'TotalCatches.user_id');
        })
        ->orderBy('TotalCatches.CatchesPerDay', 'DESC')
        ->get();

ArrayIndexOutOfBoundsException in simple words is -> you have 10 students in your class (int array size 10) and you want to view the value of the 11th student (a student who does not exist)

if you make this int i[3] then i takes values i[0] i[1] i[2]

for your problem try this code structure

double[] array = new double[50];

    for (int i = 0; i < 24; i++) {

    }

    for (int j = 25; j < 50; j++) {

    }

Ran into this issue with spring boot and jvm 1.7 and 1.8. On AWS, we did not have the option to change the ServerName and ServerAlias to match (they are different) so we did the following:

In build.gradle we added the following:

System.setProperty("jsse.enableSNIExtension", "false")
bootRun.systemProperties = System.properties

That allowed us to bypass the issue with the "Unrecognized Name".

I liked Mithun's code, but I tweaked it a bit to make it give more reasonable answers.

        {
            $totaldelay = $totaldelay % 1;
            $plural = '';
            if ($seconds > 1) $plural='s';
            $interval = $seconds." second".$plural;
            $timesince = $timesince.$first.$interval;
        }        
        return $timesince;

    }
}

This is the easiest way that I have found.

In Windows (powershell):

cat *.sql | C:\wamp64\bin\mysql\mysql5.7.21\bin\mysql.exe -u user -p database

You will need to insert the path to your WAMP - MySQL above, I have used my systems path.

In Linux (Bash):

cat *.sql | mysql -u user -p database

I just found a solution to the problem here:

http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/

The .htaccess file in webroot should look like:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

instead of this:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /projectname
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

How about

...
  C() : arr{ {1,2,3} }
{}
...

?

Compiles fine on g++ 4.8

Having trouble wrapping my head around this.

Have a rewrite rule with four conditions.
The first three conditions A, B, C are to be AND which is then OR with D

RewriteCond A       true
RewriteCond B       false
RewriteCond C [OR]  true
RewriteCond D       true
RewriteRule ...

But that seems to be an expression of A and B and (C or D) = false (don't rewrite)

How can I get to the desired expression? (A and B and C) or D = true (rewrite)

Preferably without using the additional steps of setting environment variables.

HELP!!!

You can now specify the port in the .angular-cli.json under the defaults:

"defaults": {
  "styleExt": "scss",
  "serve": {
    "port": 8080
  },
  "component": {}
}

Tested in angular-cli v1.0.6

@NoCanDo: You cannot create an array with different data types because java only supports variables with a specific data type or object. When you are creating an array, you are pulling together an assortment of similar variables -- almost like an extended variable. All of the variables must be of the same type therefore. Java cannot differentiate the data type of your variable unless you tell it what it is. Ex: int tells all your variables declared to it are of data type int. What you could do is create 3 arrays with corresponding information.

Now, a single index number gives you all the info for that book. Ex: All of your arrays with index number 0 ([0]) have information for book 1.

You can also use the box-shadow property to simulate an underline.

Here is a fiddle. The idea is to use two layered box shadows to position the line in the same place as an underline.

a.underline {
    text-decoration: none;
    box-shadow: inset 0 -4px 0 0 rgba(255, 255, 255, 1), inset 0 -5px 0 0 rgba(255, 0, 0, 1);
}

Combining what Dick Lucas says and adding a reset autoincremental from other StackOverFlow posts, i think this can work:

fun clearAndResetAllTables(): Boolean {
    val db = db ?: return false

    // reset all auto-incrementalValues
    val query = SimpleSQLiteQuery("DELETE FROM sqlite_sequence")

    db.beginTransaction()
    return try {
        db.clearAllTables()
        db.query(query)
        db.setTransactionSuccessful()
        true
    } catch (e: Exception){
        false
    } finally {
        db.endTransaction()
    }
}

If you just want to give users using a MS browser a warning or something, this code should be good.

HTML:

<p id="IE">You are not using a microsoft browser</p>

Javascript:

using_ms_browser = navigator.appName == 'Microsoft Internet Explorer' || (navigator.appName == "Netscape" && navigator.appVersion.indexOf('Edge') > -1) || (navigator.appName == "Netscape" && navigator.appVersion.indexOf('Trident') > -1);

if (using_ms_browser == true){
    document.getElementById('IE').innerHTML = "You are using a MS browser"
}

Sometimes, casting an Int to a Double is not a viable solution. At some magnitudes there is a loss of precision in this conversion. For example, the following code does not return what you might intuitively expect.

Double(Int.max - 1) < Double(Int.max) // false!

If you need precision at high magnitudes and don't need to worry about negative exponents — which can't be generally solved with integers anyway — then this implementation of the tail-recursive exponentiation-by-squaring algorithm is your best bet. According to this SO answer, this is "the standard method for doing modular exponentiation for huge numbers in asymmetric cryptography."

// using Swift 5.0
func pow<T: BinaryInteger>(_ base: T, _ power: T) -> T {
    func expBySq(_ y: T, _ x: T, _ n: T) -> T {
        precondition(n >= 0)
        if n == 0 {
            return y
        } else if n == 1 {
            return y * x
        } else if n.isMultiple(of: 2) {
            return expBySq(y, x * x, n / 2)
        } else { // n is odd
            return expBySq(y * x, x * x, (n - 1) / 2)
        }
    }

    return expBySq(1, base, power) 
}

Note: in this example I've used a generic T: BinaryInteger. This is so you can use Int or UInt or any other integer-like type.

(In addition of the official "GitHub Help 'Using pull requests' page",
see also "Forking vs. Branching in GitHub", "What is the difference between origin and upstream in GitHub")

Couple tips on pull-requests:

Assuming that you have first forked a repo, here is what you should do in that fork that you own:

• create a branch: isolate your modifications in a branch. Don't create a pull request from master, where you could be tempted to accumulate and mix several modifications at once.
• rebase that branch: even if you already did a pull request from that branch, rebasing it on top of origin/master (making sure your patch is still working) will update the pull request automagically (no need to click on anything)
• update that branch: if your pull request is rejected, you simply can add new commits, and/or redo your history completely: it will activate your existing pull request again.
• "focus" that branch: i.e., make its topic "tight", don't modify thousands of class and the all app, only add or fix a well-defined feature, keeping the changes small.
• delete that branch: once accepted, you can safely delete that branch on your fork (and git remote prune origin). The GitHub GUI will propose for you to delete your branch in your pull-request page.

Note: to write the Pull-Request itself, see "How to write the perfect pull request" (January 2015, GitHub)

March 2016: New PR merge button option: see "Github squash commits from web interface on pull request after review comments?".

The maintainer of the repo can chose to merge --squash those PR commits.

After a Pull Request

Regarding the last point, since April, 10th 2013, "Redesigned merge button", the branch is deleted for you:

Deleting branches after you merge has also been simplified.
Instead of confirming the delete with an extra step, we immediately remove the branch when you delete it and provide a convenient link to restore the branch in the event you need it again.

That confirms the best practice of deleting the branch after merging a pull request.

pull-request vs. request-pull

• pull request isn't an official "git" term.
  Git uses the request-pull(!) command to build a request for merging:
  It "summarizes the changes between two commits to the standard output, and includes the given URL in the generated summary."
  Github launches its own version since day one (February 2008), but redesigned that feature in May 2010, stating that:

  Pull Request = Compare View + Issues + Commit comments
  

e-notes for "reposotory" (sic)

<humour>

That (pull request) isn't even defined properly by GitHub!

Fortunately, a true business news organization would know, and there is an e-note in order to replace pull-replace by 'e-note':

So if your reposotory needs a e-note... ask Fox Business. They are in the know.

To decompile APK Use APKTool.
You can learn how APKTool works on http://www.decompileandroid.com/ or by reading the documentation.

Here :name is the symbol which point to the method name of tag object. When we pass &:name to map, it will treat name as a proc object. For short, tags.map(&:name) acts as:

tags.map do |tag|
  tag.name
end

For others, if clearfix does not solve this for you, add margins to the non-floated sibling that is/are the same as the width(s) of the floated sibling(s).

To put text, use .text('text')

If you want to use .html(SomeValue), SomeValue should have html tags that can be inside a div it must work too.

Just check your script location, as farzad said.

Reference: .html and text

When you call the function in a static context, $this simply doesn't exist.

You would have to use this::xyz() instead.

To find out what context you're in when a function can be called both statically and in an object instance, a good approach is outlined in this question: How to tell whether I’m static or an object?

It seems the doc evolved.

One should now use : $("#datetimepicker1").data("DateTimePicker").date().

NB : Doing so return a Moment object, not a Date object

for any1 using ie8 and dont want to use a plugin i've made something inspired by Rohit Azad and Bacotasan's blog, i just added a span using JS to show the selected value.

the html:

<div class="styled-select">
   <select>
      <option>Here is the first option</option>
      <option>The second option</option>
   </select>
   <span>Here is the first option</span>
</div>

the css (i used only an arrow for BG but you could put a full image and drop the positioning):

.styled-select div
{
    display:inline-block;
    border: 1px solid darkgray;
    width:100px;
    background:url("/Style Library/Nifgashim/Images/drop_arrrow.png") no-repeat 10px 10px;
    position:relative;
}

.styled-select div select
{
    height: 30px;
    width: 100px;
    font-size:14px;
    font-family:ariel;

    -moz-opacity: 0.00;
    opacity: .00;
    filter: alpha(opacity=00);
}

.styled-select div span
{
    position: absolute;
    right: 10px;
    top: 6px;
    z-index: -5;
}

the js:

$(".styled-select select").change(function(e){
     $(".styled-select span").html($(".styled-select select").val());
});

import java.util.Scanner;
public class JavaApplication1 {


    public static void main(String[] args) {

         int x,
         int y;

         Scanner input=new Scanner(System.in);
         System.out.println("Enter Number 1");
         x=input.nextInt();
         System.out.println("Enter Number 2");
         y=input.nextInt();

         System.out.println("Please enter operation + - / or *");
         Scanner op=new Scanner(System.in);
         String operation = op.next();

         if (operation.equals("+")){
             System.out.println("Your Answer: " + (x+y));
         }
         if (operation.equals("-")){
             System.out.println("Your Answer: "+ (x-y));
         }
         if (operation.equals("/")){
             System.out.println("Your Answer: "+ (x/y));
         }
         if (operation.equals("*")){
            System.out.println("Your Answer: "+ (x*y));
         }
    }

Sometimes, Clover is configured to provide code coverage reports for all non-test code. If you wish to override these preferences, you may use configuration elements to exclude and include source files from being instrumented:

<plugin>
    <groupId>com.atlassian.maven.plugins</groupId>
    <artifactId>maven-clover2-plugin</artifactId>
    <version>${clover-version}</version>
    <configuration> 
        <excludes> 
            <exclude>**/*Dull.java</exclude> 
        </excludes> 
    </configuration>
</plugin>

Also, you can include the following Sonar configuration:

<properties>
    <sonar.exclusions>
        **/domain/*.java,
        **/transfer/*.java
    </sonar.exclusions>
</properties> 

Under "Project -> Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions" add _CRT_SECURE_NO_WARNINGS

composer.phar can be ran on its own, no need to prefix it with php. This should solve your problem (being in the difference of bash's $PATH and php's include_path).

If you are using unix, you need to write a shellscript to run you java batch first.

After that, in unix, you run this command "crontab -e" to edit crontab script. In order to configure crontab, please refer to this article http://www.thegeekstuff.com/2009/06/15-practical-crontab-examples/

Save your crontab setting. Then wait for the time to come, program will run automatically.

ReSharper does a great job of finding unused code.

In the VS IDE, you can right click on the definition and choose 'Find All References', although this only works at the solution level.

I got this error when upgrading

gulp-typescript 3.0.2 ? 3.1.0

Putting it back to 3.0.2 fixed it

You can simply try it with a jenkinsfile. Create a Jenkins job with following pipeline script.

pipeline {
    agent any

    parameters {
        booleanParam(defaultValue: true, description: '', name: 'userFlag')
    }

    stages {
        stage('Trigger') {
            steps {
                script {
                    println("triggering the pipeline from a rest call...")
                }
            }
        }
        stage("foo") {
            steps {
                echo "flag: ${params.userFlag}"
            }
        }

    }
}

Build the job once manually to get it configured & just create a http POST request to the Jenkins job as follows.

The format is http://server/job/myjob/buildWithParameters?PARAMETER=Value

curl http://admin:test123@localhost:30637/job/apd-test/buildWithParameters?userFlag=false --request POST

You could use CSS for this and create classes for the elements. So you'd have something like this

p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }

Then your HTML would read:

<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>

It's a lot neater then inline stylesheets, is easier to maintain and provides greater reuse.

Here's the complete HTML to demonstrate what I mean:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <style type="text/css">
    p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
    span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
    </style>
</head>
<body>
    <p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
</body>
</html>     

You'll see that I have the stylesheet classes in a style tag in the header, and then I only apply those classes in the code such as <p class="detail"> ... </p>. Go through the w3schools tutorial, it will only take a couple of hours and will really turn you around when it comes to styling your HTML elements. If you cut and paste that into an HTML document you can edit the styles and see what effect they have when you open the file in a browser. Experimenting like this is a great way to learn.

if you have two application like (your app, phpmyadmin) just disable APC extension Hope that fix that issue it's worked with me

Pragma mark - [SOME TEXT HERE] was used in Objective-C to group several function together by line separating.

In Swift you can achieve this using MARK, TODO OR FIXME

i. MARK : //MARK: viewDidLoad

This will create a horizontal line with functions grouped under viewDidLoad(shown in screenshot 1)

ii. TODO : //TODO: - viewDidLoad

This will group function under TODO: - viewDidLoad category (shown in screenshot 2)

iii. FIXME : //FIXME - viewDidLoad

This will group function under FIXME: - viewDidLoad category (shown in screenshot 3)

Check this apple documentation for details.

try this:

.topics tr { line-height: 14px; }

There are indeed global variables in javascript. You can learn more about scopes, which are helpful in this situation.

Your code could look like this:

<script>
    var count = 1;
    function setColor(btn, color) {
        var property = document.getElementById(btn);
        if (count == 0) {
            property.style.backgroundColor = "#FFFFFF"
            count = 1;        
        }
        else {
            property.style.backgroundColor = "#7FFF00"
            count = 0;
        }
    }
</script>

Hope this helps.

For anyone checking this using python 3:

If you want to print the following output "100% correct":

python 3.8: print("100% correct")
python 3.7 and less: print("100%% correct")

A neat programming workaround for compatibility across diff versions of python is shown below:

Note: If you have to use this, you're probably experiencing many other errors... I'd encourage you to upgrade / downgrade python in relevant machines so that they are all compatible.

DevOps is a notable exception to the above -- implementing the following code would indeed be appropriate for specific DevOps / Debugging scenarios.

import sys

if version_info.major==3:
    if version_info.minor>=8:
        my_string = "100% correct"
    else:
        my_string = "100%% correct"

# Finally
print(my_string)

My answer is based on getting a 403 error although I had all of the Apache settings mentioned in the other answers correct.

It was a fresh Centos 7 server and it turned out that the issue was not the Apache settings but the fact that the PhpMyAdmin did not serve at all. The solution was to install php and add the php directive to apache.conf:

• sudo yum install php php-mysql
• vim /etc/httpd/conf/httpd.conf add something like
• DirectoryIndex index.php index.phtml index.html index.htm to serve php index files also and then restart apache

Don't forget to restart Apache server to take effect - systemctl restart httpd.service

I hope this helps. I first thought my issue was Apache directives, so I post my solution here.

Even though there are already many many answers to this post, I feel I have to add another option for unix hosts that only returns the sum of all file sizes in the directory (recursively).

If you look at Jonathan's answer he uses the du command. This command will return the total directory size but the pure PHP solutions posted by others here will return the sum of all file sizes. Big difference!

What to look out for

When running du on a newly created directory, it may return 4K instead of 0. This may even get more confusing after having deleted files from the directory in question, having du reporting a total directory size that does not correspond to the sum of the sizes of the files within it. Why? The command du returns a report based on some file settings, as Hermann Ingjaldsson commented on this post.

The solution

To form a solution that behaves like some of the PHP-only scripts posted here, you can use ls command and pipe it to awk like this:

ls -ltrR /path/to/dir |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'

As a PHP function you could use something like this:

function getDirectorySize( $path )
{
    if( !is_dir( $path ) ) {
        return 0;
    }

    $path   = strval( $path );
    $io     = popen( "ls -ltrR {$path} |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'", 'r' );
    $size   = intval( fgets( $io, 80 ) );
    pclose( $io );

    return $size;
}

You need to set a height on the DIV. Otherwise it will keep expanding indefinitely.

Simple code for you it will work

private void dgv_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (dgv.CurrentRow.Cells["ColumnNumber"].Value != null && (bool)dgv.CurrentRow.Cells["ColumnNumber"].Value)
    {
        dgv.CurrentRow.Cells["ColumnNumber"].Value = false;
        dgv.CurrentRow.Cells["ColumnNumber"].Value = null;
    }
    else if (dgv.CurrentRow.Cells["ColumnNumber"].Value == null )
    {
        dgv.CurrentRow.Cells["ColumnNumber"].Value = true;
    }
}

If you don't want to build custom filter then you can use directly

{{ foo.awesome_property.substring(0,1) | uppercase}}{{foo.awesome_property.substring(1)}}

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i(TAG, "On Create .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onDestroy()
    */
    @Override
    protected void onDestroy() { 
        super.onDestroy();
        Log.i(TAG, "On Destroy .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onPause()
    */
    @Override
    protected void onPause() { 
        super.onPause();
        Log.i(TAG, "On Pause .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onRestart()
    */
    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i(TAG, "On Restart .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onResume()
    */
    @Override
    protected void onResume() {
        super.onResume();
        Log.i(TAG, "On Resume .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onStart()
    */
    @Override
    protected void onStart() {
        super.onStart();
        Log.i(TAG, "On Start .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onStop()
    */
    @Override
    protected void onStop() {
        super.onStop();
        Log.i(TAG, "On Stop .....");
    }
}

Hope this will clear your confusion.

And take a look here for details.

Lifecycle Methods in Details is a very good example and demo application, which is a very good article to understand the life cycle.

This is possible if you have an existing Newline character in the row or another row.

Select the square-box that represents the existing Newline character, copy it (control-C), and then paste it (control-V) where you want it to be.

This is slightly cheesy, but I actually did get it to work in SSMS 2008 and I was not able to get any of the other suggestions (control-enter, alt-13, or any alt-##) to work.

Just adding on to @Mitch Dempsy answer since I don't have enough rep to comment yet.

svn export -r <REV> svn://host/path/to/file/on/repos --force

Adding the --force will overwrite the local copy with the export and then you can do an svn commit to push it to the repository.

$('#element').on('change', function() {
    $(this).val($(this).prop("defaultValue"));
});

It must be here, because accepted answer from 2012

In 2018 and modern browsers you can send a custom event from iframe to parent window.

iframe:

var data = { foo: 'bar' }
var event = new CustomEvent('myCustomEvent', { detail: data })
window.parent.document.dispatchEvent(event)

parent:

window.document.addEventListener('myCustomEvent', handleEvent, false)
function handleEvent(e) {
  console.log(e.detail) // outputs: {foo: 'bar'}
}

PS: Of course, you can send events in opposite direction same way.

document.querySelector('#iframe_id').contentDocument.dispatchEvent(event)

System.setProperty("gate.home", "/some/directory");

For more information, see:

• The System Properties tutorial.
• Class doc for System.setProperty( String key , String value ).

Here's a simple modern approach to this with useState, useEffect and useRef in ES6.

import React, { useRef, useState, useEffect } from 'react'

const quickAndDirtyStyle = {
  width: "200px",
  height: "200px",
  background: "#FF9900",
  color: "#FFFFFF",
  display: "flex",
  justifyContent: "center",
  alignItems: "center"
}

const DraggableComponent = () => {
  const [pressed, setPressed] = useState(false)
  const [position, setPosition] = useState({x: 0, y: 0})
  const ref = useRef()

  // Monitor changes to position state and update DOM
  useEffect(() => {
    if (ref.current) {
      ref.current.style.transform = `translate(${position.x}px, ${position.y}px)`
    }
  }, [position])

  // Update the current position if mouse is down
  const onMouseMove = (event) => {
    if (pressed) {
      setPosition({
        x: position.x + event.movementX,
        y: position.y + event.movementY
      })
    }
  }

  return (
    <div
      ref={ ref }
      style={ quickAndDirtyStyle }
      onMouseMove={ onMouseMove }
      onMouseDown={ () => setPressed(true) }
      onMouseUp={ () => setPressed(false) }>
      <p>{ pressed ? "Dragging..." : "Press to drag" }</p>
    </div>
  )
}

export default DraggableComponent

I tried all the above and still my Visual Studio 2012 did not show up the tests. In the end I went to a test class and found it had a RootNamespace.FolderName and I removed the .FolderName to put the class in the root namespace and bingo all the tests came back!

Cannot understand why it was working fine with the original namespace till the other day.

1. Pure POSIX shell and sponge:

   suffix=foobar
   while read l ; do printf '%s\n' "$l" "${suffix}" ; done < file | 
   sponge file
   

2. xargs and printf:

   suffix=foobar
   xargs -L 1 printf "%s${suffix}\n" < file | sponge file
   

3. Using join:

   suffix=foobar
   join file file -e "${suffix}" -o 1.1,2.99999 | sponge file
   

4. Shell tools using paste, yes, head & wc:

   suffix=foobar
   paste file <(yes "${suffix}" | head -$(wc -l < file) ) | sponge file
   

   Note that paste inserts a Tab char before $suffix.

Of course sponge can be replaced with a temp file, afterwards mv'd over the original filename, as with some other answers...

If you are using a git server inside a private network and are using a self-signed certificate or a certificate over an IP address ; you may also simply use the git global config to disable the ssl checks:

git config --global http.sslverify "false"

To get rid of permission errors (and such), you can redirect stderr to nowhere

find / -name "something" 2>/dev/null

I ran into this trying to integrate React Native into an existing swift project using cocoapods. The FB docs (at time of writing) did not specify that npm install react-native wouldn't work without first having a package.json file. Per the RN docs set your entry point: (index.js) as index.ios.js

If you want to enable unblur, you cannot just add the blur CSS to the body, you need to blur each visible child one level directly under the body and then remove the CSS to unblur. The reason is because of the "Cascade" in CSS, you cannot undo the cascading of the CSS blur effect for a child of the body. Also, to blur the body's background image you need to use the pseudo element :before

In my case I was doing something like the following:

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

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

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

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

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

You need to load the URL Helper in order to use base_url(). In your controller, do:

$this->load->helper('url');

Then in your view you can do:

echo base_url();

Here's a working sample of NSNumberFormatter reading localized number NSString (xCode 3.2.4, osX 10.6), to save others the hours I've just spent messing around. Beware: while it can handle trailing blanks ("8,765.4 " works), this cannot handle leading white space and this cannot handle stray text characters. (Bad input strings: " 8" and "8q" and "8 q".)

NSString *tempStr = @"8,765.4";  
     // localization allows other thousands separators, also.
NSNumberFormatter * myNumFormatter = [[NSNumberFormatter alloc] init];
[myNumFormatter setLocale:[NSLocale currentLocale]]; // happen by default?
[myNumFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
     // next line is very important!
[myNumFormatter setNumberStyle:NSNumberFormatterDecimalStyle]; // crucial

NSNumber *tempNum = [myNumFormatter numberFromString:tempStr];
NSLog(@"string '%@' gives NSNumber '%@' with intValue '%i'", 
    tempStr, tempNum, [tempNum intValue]);
[myNumFormatter release];  // good citizen

You don't need to use del to delete instances in the first place. Once the last reference to an object is gone, the object will be garbage collected. Maybe you should tell us more about the full problem.

I might understand the question incorrectly, but if you want to declare an array of a certain shape but with nothing inside, the following might be helpful:

Initialise empty array:

>>> a = np.zeros((0,3)) #or np.empty((0,3)) or np.array([]).reshape(0,3)
>>> a
array([], shape=(0, 3), dtype=float64)

Now you can use this array to append rows of similar shape to it. Remember that a numpy array is immutable, so a new array is created for each iteration:

>>> for i in range(3):
...     a = np.vstack([a, [i,i,i]])
...
>>> a
array([[ 0.,  0.,  0.],
       [ 1.,  1.,  1.],
       [ 2.,  2.,  2.]])

np.vstack and np.hstack is the most common method for combining numpy arrays, but coming from Matlab I prefer np.r_ and np.c_:

Concatenate 1d:

>>> a = np.zeros(0)
>>> for i in range(3):
...     a = np.r_[a, [i, i, i]]
...
>>> a
array([ 0.,  0.,  0.,  1.,  1.,  1.,  2.,  2.,  2.])

Concatenate rows:

>>> a = np.zeros((0,3))
>>> for i in range(3):
...     a = np.r_[a, [[i,i,i]]]
...
>>> a
array([[ 0.,  0.,  0.],
       [ 1.,  1.,  1.],
       [ 2.,  2.,  2.]])

Concatenate columns:

>>> a = np.zeros((3,0))
>>> for i in range(3):
...     a = np.c_[a, [[i],[i],[i]]]
...
>>> a
array([[ 0.,  1.,  2.],
       [ 0.,  1.,  2.],
       [ 0.,  1.,  2.]])

Use the open function to open the file. The open function returns a file object, which you can use the read and write to files:

file_input = open('input.txt') #opens a file in reading mode
file_output = open('output.txt') #opens a file in writing mode

data = file_input.read(1024) #read 1024 bytes from the input file
file_output.write(data) #write the data to the output file

This problem is because of your https that means SSL certification. Try on Localhost.

T-SQL is not asynchronous, so you really have no choice but to wait until SP2 ends. Luckily, that's what you want.

CREATE PROCEDURE SP1 AS
   EXEC SP2
   PRINT 'Done'

I am not completely sure what you're trying to achieve by seeking to a specific offset and attempting to load individual values manually, the typical usage of the pickle module is:

# save data to a file
with open('myfile.pickle','wb') as fout:
    pickle.dump([1,2,3],fout)

# read data from a file
with open('myfile.pickle') as fin:
    print pickle.load(fin)

# output
>> [1, 2, 3]

If you dumped a list, you'll load a list, there's no need to load each item individually.

you're saying that you got an error before you were seeking to the -5000 offset, maybe the file you're trying to read is corrupted.

If you have access to the original data, I suggest you try saving it to a new file and reading it as in the example.

Your struct is called struct xyx but a is of type struct xyz. Once you fix that, the output is 100.

#include <stdio.h>

struct xyx {
    int x;
    int y;
    char c;
    char str[20];
    int arr[2];
};

int main(void)
{
    struct xyx a;
    a.x = 100;
    printf("%d\n", a.x);
    return 0;
}

Have you tried Server.MapPath method. Here is an example

string relative_path = "/Content/img/Upload/Reports/59/44A0446_59-1.jpg";
string absolute_path = Server.MapPath(relative_path);
//will be c:\users\.....\Content\img\Upload\Reports\59\44A0446_59-1.jpg

One advantage not yet mentioned of a TreeSet is that its has greater "locality", which is shorthand for saying (1) if two entries are nearby in the order, a TreeSet places them near each other in the data structure, and hence in memory; and (2) this placement takes advantage of the principle of locality, which says that similar data is often accessed by an application with similar frequency.

This is in contrast to a HashSet, which spreads the entries all over memory, no matter what their keys are.

When the latency cost of reading from a hard drive is thousands of times the cost of reading from cache or RAM, and when the data really is accessed with locality, the TreeSet can be a much better choice.

I had the same issue with Axios requests in a Vue-CLI App. On further checking in Network tab of Chrome, I found that the request URL of axios correctly had https but response 'location' header was http.

This was caused by nginx and I fixed it by adding these 2 lines to server config for nginx:

server {
    ...
    add_header Strict-Transport-Security "max-age=31536000" always;
    add_header Content-Security-Policy upgrade-insecure-requests;
    ...
}

Might be irrelevant but my Vue-CLI App was served under a subpath in nginx with config as:

location ^~ /admin {
        alias   /home/user/apps/app_admin/dist;
        index  index.html;
        try_files $uri $uri/ /index.html;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Host $host;
}

Your first reaction to these methods is quite interesting to me. I will use it in future arguments that both assertTrue and assertFalse are not the most friendly tools. If you would use

assertThat(thisOrThat, is(false));

it is much more readable, and it prints a better error message too.

You can use data-* attribute to embed custom data. The data-* attributes gives us the ability to embed custom data attributes on all HTML elements.

jQuery .data() method allows you to get/set data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks.

jQuery .attr() method get/set attribute value for only the first element in the matched set.

Example:

<span id="test" title="foo" data-kind="primary">foo</span>

$("#test").attr("title");
$("#test").attr("data-kind");
$("#test").data("kind");
$("#test").data("value", "bar");

Static function means that it is associated with class (not a particular instance of class but the class itself) and it can be invoked even when no class instances exist.

Static class means that class contains only static members.

What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.

E.g.

<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

Try This.

Use raw_input instead of input :)

If you use input, then the data you type is is interpreted as a Python Expression which means that you end up with gawd knows what type of object in your target variable, and a heck of a wide range of exceptions that can be generated. So you should NOT use input unless you're putting something in for temporary testing, to be used only by someone who knows a bit about Python expressions.

raw_input always returns a string because, heck, that's what you always type in ... but then you can easily convert it to the specific type you want, and catch the specific exceptions that may occur. Hopefully with that explanation, it's a no-brainer to know which you should use.

Reference

Note: this is only for Python 2. For Python 3, raw_input() has become plain input() and the Python 2 input() has been removed.

you can use the following common function.

<div>
     <select class="form-control" 
             name="Extension for area validity sought for" 
             onchange="CommonShowHide('txtc1opt2', this, 'States')"
     >
         <option value="All India">All India</option>
         <option value="States">States</option>
     </select>

     <input type="text" 
            id="txtc1opt2" 
            style="display:none;" 
            name="Extension for area validity sought for details" 
            class="form-control" 
            value="" 
            placeholder="">

</div>

<script>
    function CommonShowHide(ElementId, element, value) {
         document
             .getElementById(ElementId)
             .style
             .display = element.value == value ? 'block' : 'none';
    }
</script>

HP computer method:

Make sure your BIOS is updated before changing the settings. If you have an HP computer, they have an HP Support Assistant app you can configure to automatically install BIOS updates. Then follow the instructions on how to update BIOS.

Then you can look up which HP computer for how to change the BIOS in a search engine.

For an HP ZBook, follow these steps:

1. Restart your computer with the shift key pressed (before you click restart) until a menu appears.
2. Choose BIOS Setup on the screen (or press F10).
3. Click on Troubleshoot.
4. Using your arrow keys in this menu, go to Advanced Options.
5. Select UEFI Firmware Settings.
6. Select restart.
7. It reboots into a Startup menu
8. Choose BIOS Setup With arrow keys go to Advanced tab.
9. Choose the System Options.
10. Check both the Virtualization Technology (VTx) and the Virtualization Technology for Directed I/O (VTd) boxes.
11. Go back to the Main tab and at bottom choose Save and Exit.
12. Computer will restart.

here is another way to do such

 private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        dataGridView1.ColumnCount = 3;

        dataGridView1.Columns[0].Name = "Name";
        dataGridView1.Columns[1].Name = "Age";
        dataGridView1.Columns[2].Name = "City";

        dataGridView1.Rows.Add("kathir", "25", "salem");
        dataGridView1.Rows.Add("vino", "24", "attur");
        dataGridView1.Rows.Add("maruthi", "26", "dharmapuri");
        dataGridView1.Rows.Add("arun", "27", "chennai"); 
    }

With .Net Core it is now very easy:

1. You go and find JSON URL on your swagger page:

2. Click that link and copy the URL
3. Now go to Postman and click Import:

4. Select what you need and you end up with a nice collection of endpoints:

This looks a little ugly. Is it possible to cast an entire stream to a different type? Like cast Stream<Object> to a Stream<Client>?

No that wouldn't be possible. This is not new in Java 8. This is specific to generics. A List<Object> is not a super type of List<String>, so you can't just cast a List<Object> to a List<String>.

Similar is the issue here. You can't cast Stream<Object> to Stream<Client>. Of course you can cast it indirectly like this:

Stream<Client> intStream = (Stream<Client>) (Stream<?>)stream;

but that is not safe, and might fail at runtime. The underlying reason for this is, generics in Java are implemented using erasure. So, there is no type information available about which type of Stream it is at runtime. Everything is just Stream.

BTW, what's wrong with your approach? Looks fine to me.

Just remove css from your js fiddle, ng-show will controll it. AngularJS sets the display style to none (using an !important flag). And remove this class when it must be shown.

Step 1: Open the .xcodeworkspace project in your xcode by navigating it via "Terminal", "open /ios/.xcodeworkspace" Hit Enter.

Step 2: Delete the main.jsbundle file inside the folder you have

Step 3: Go back to VS Code, type this, react-native bundle --entry-file index.js --platform ios --dev false --bundle-output ios/main.jsbundle --assets-dest ios

This generate you the new main.jsbundle file.

Step 4: react-native run-ios

you wont see the error again

You are using datetimepicker when it should be datepicker. As per the docs. Try this and it should work.

<script type="text/javascript">
  $(function () {
    $('#datetimepicker9').datepicker({
      viewMode: 'years'
    });
  });
 </script>

Based on bnkdev's answer I modified Narayana's Code to search all columns even numeric ones.

It'll run slower, but this version actually finds all matches not just those found in text columns.

I can't thank this guy enough. Saved me days of searching by hand!

Recycler View in Horizontal Dynamic.

Recycler View Implementation

RecyclerView musicList = findViewById(R.id.MusicList);

// RecyclerView musiclist = findViewById(R.id.MusicList1);
// RecyclerView musicLIST = findViewById(R.id.MusicList2);
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
musicList.setLayoutManager(layoutManager);

String[] names = {"RAP", "CH SHB", "Faheem", "Anum", "Shoaib", "Laiba", "Zoki", "Komal", "Sultan","Mansoob Gull"};
musicList.setAdapter(new ProgrammingAdapter(names));'

Adapter class for recycler view, in which there is is a view holder for holding view of that recycler

public class ProgrammingAdapter 
     extendsRecyclerView.Adapter<ProgrammingAdapter.programmingViewHolder> {

private String[] data;

public ProgrammingAdapter(String[] data)
{
    this.data = data;
}

@Override
public programmingViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View view = inflater.inflate(R.layout.list_item_layout, parent, false);

    return new programmingViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull programmingViewHolder holder, int position) {
    String title = data[position];
    holder.textV.setText(title);

Use services (start -> run -> services.msc) and look for the postgresql-[version] service.

• If it is not there you might have just installed pgAdmin and not installed PostgreSQL itself.
• If it is not running try to start it, if it won't start open the event-viewer (start -> run -> eventvwr) and look for error messages relating to the PostgreSQL service.
• If it does start check the startup type, if you want it to start with windows it should be "Automatic"; or perhaps "Automatic, delayed start" if you don't want it to slow down startup too much.

Adding to the first, because in a different comment you've said the service isn't there. It is possible to download a standalone pgAdmin so you can connect to an external PostgreSQL database. It would seem you have done such a thing, or explicitly chosen to not add the service. Just try the One Click Installer, which still allows proper configuration of installation directory despite its name.

I created a working demo of a landscape/portrait layout but the zoom must be disabled for it to work without JavaScript:

http://matthewjamestaylor.com/blog/ipad-layout-with-landscape-portrait-modes

How about something like this:

SELECT c.constraint_name, c.constraint_type, c2.constraint_name, c2.constraint_type, c2.table_name
  FROM dba_constraints c JOIN dba_constraints c2 ON (c.r_constraint_name = c2.constraint_name)
 WHERE c.table_name = <TABLE_OF_INTEREST>
   AND c.constraint_TYPE = 'R';

I like the answers from The Aelfinn and aheld. I can improve them only by shortening a bit more, removing superfluous pieces, using a real data source, making it 2.x & 3.x-compatible, and maintaining the high-level of memory-efficiency seen elsewhere:

import csv
import requests

CSV_URL = 'http://web.cs.wpi.edu/~cs1004/a16/Resources/SacramentoRealEstateTransactions.csv'

with requests.get(CSV_URL, stream=True) as r:
    lines = (line.decode('utf-8') for line in r.iter_lines())
    for row in csv.reader(lines):
        print(row)

Too bad 3.x is less flexible CSV-wise because the iterator must emit Unicode strings (while requests does bytes) while the 2.x-only version—for row in csv.reader(r.iter_lines()):—is more Pythonic (shorter and easier-to-read). Anyhow, note the 2.x/3.x solution above won't handle the situation described by the OP where a NEWLINE is found unquoted in the data read.

For the part of the OP's question regarding downloading (vs. processing) the actual CSV file, here's another script that does that, 2.x & 3.x-compatible, minimal, readable, and memory-efficient:

import os
import requests

CSV_URL = 'http://samplecsvs.s3.amazonaws.com/Sacramentorealestatetransactions.csv'

with open(os.path.split(CSV_URL)[1], 'wb') as f, \
        requests.get(CSV_URL, stream=True) as r:
    for line in r.iter_lines():
        f.write(line+'\n'.encode())

Maven

The Answer by Bhesh Gurung is correct… unless your NetBeans project is Maven based.

Dependency

Under Maven, you add a "dependency". A dependency is a description of a library (its name & version number) you want to use from your code.

Or a dependency could be a description of a library which another library needs ("depends on"). Maven automatically handles this chain, libraries that need other libraries that then need other libraries and so on. For the mathematical-minded, perhaps the phrase "Maven resolves the transitive dependencies" makes sense.

Repository

Maven gets this related-ness information, and the libraries themselves from a Maven repository. A repository is basically an online database and collection of download files (the dependency library).

Easy to Use

Adding a dependency to a Maven-based project is really quite easy. That is the whole point to Maven, to make managing dependent libraries easy and to make building them into your project easy. To get started with adding a dependency, see this Question, Adding dependencies in Maven Netbeans and my Answer with screenshot.

Append the below Script in Console:

window.addEventListener("beforeunload", function(event) { 
     console.log("The page is redirecting")           
     debugger; 
});

specifically I want to overload Boolean.Parse to allow an int argument.

Would an extension for int work?

public static bool ToBoolean(this int source){
    // do it
    // return it
}

Then you can call it like this:

int x = 1;

bool y = x.ToBoolean();

A very simple way to count the columns of the first line in pure bash (no awk, perl, or other languages):

read -r line < $input_file
ncols=`echo $line | wc -w`

This will work if your data are formatted appropriately.

I think you can do what you want to do by running the build via a docker command which itself is run inside a docker container. See Docker can now run within Docker | Docker Blog. A technique like this, but which actually accessed the outer docker from with a container, was used, e.g., while exploring how to Create the smallest possible Docker container | Xebia Blog.

Another relevant article is Optimizing Docker Images | CenturyLink Labs, which explains that if you do end up downloading stuff during a build, you can avoid having space wasted by it in the final image by downloading, building and deleting the download all in one RUN step.

function findIndexByKeyValue(_array, key, value) {
    for (var i = 0; i < _array.length; i++) { 
        if (_array[i][key] == value) {
            return i;
        }
    }
    return -1;
}
var a = [
    {prop1:"abc",prop2:"qwe"},
    {prop1:"bnmb",prop2:"yutu"},
    {prop1:"zxvz",prop2:"qwrq"}];
var index = findIndexByKeyValue(a, 'prop2', 'yutu');
console.log(index);

To further generalize @Alexander's example, outer is relevant in cases where a function must compute itself on each pair of vector values:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
outer(vars1,vars2,mult_one)

gives:

> outer(vars1, vars2, mult_one)
     [,1] [,2] [,3]
[1,]   10   20   30
[2,]   20   40   60
[3,]   30   60   90

This has been working for me:

`ls -F | grep /`

(But, I am switching to echo */ as mentioned by @nos)

The readonly keyword is used to declare a member variable a constant, but allows the value to be calculated at runtime. This differs from a constant declared with the const modifier, which must have its value set at compile time. Using readonly you can set the value of the field either in the declaration, or in the constructor of the object that the field is a member of.

Also use it if you don't want to have to recompile external DLLs that reference the constant (since it gets replaced at compile time).

Multi joins in SQL work by progressively creating derived tables one after the other. See this link explaining the process:

https://www.interfacett.com/blogs/multiple-joins-work-just-like-single-joins/

Another use case is when using the SQL Server 2016+ functionality of AT TIME ZONE

The below statement will return a date converted to GMT

SELECT 
CONVERT(DATETIME, SWITCHOFFSET([ColumnA], DATEPART(TZOFFSET, [ColumnA] AT TIME ZONE 'GMT Standard Time')))

If you want to pass the time zone as a variable, say:

SELECT 
CONVERT(DATETIME, SWITCHOFFSET([ColumnA], DATEPART(TZOFFSET, [ColumnA] AT TIME ZONE @TimeZone)))

then that variable needs to be of the type sysname (declaring it as varchar will cause an error).

I fixed it by removing float:left, and adding display:inline-block instead. Haven't used it for images, but should work fine, there, too.

You can use this:

@Override

 public boolean shouldOverrideUrlLoading(WebView view, String url) {

                // Here put your code
                Map<String, String> map = new HashMap<String, String>();
                map.put("Content-Type","application/json");
                view.loadUrl(url, map);
                return false;

            }

You could just style the input element in your css file. That is then independent of ASP.NET.

<form action="">
    Name: <input type="text" class="input" />
    Password: <input type="password" class="input" />
    <input type="submit" value="Submit" class="button" />
</form>
CSS
.input {
    border: 1px solid #006;
    background: #ffc;
}
.button {
    border: 1px solid #006;
    background: #9cf;
}

With the CssClass you can assign the "input" class to it.

This only worked for me:

android:windowSoftInputMode="adjustPan"

Use IndexOf is easier and high performance.

int index = Value1.IndexOf("abc");
bool found = index >= 0 && index < x;

What about .GlobalEnv$a <- "new" ? I saw this explicit way of creating a variable in a certain environment here: http://adv-r.had.co.nz/Environments.html. It seems shorter than using the assign() function.

The following are some guidelines.

A function uses passed data without modifying it:

1. If the data object is small, such as a built-in data type or a small structure, pass it by value.

2. If the data object is an array, use a pointer because that’s your only choice. Make the pointer a pointer to const.

3. If the data object is a good-sized structure, use a const pointer or a const reference to increase program efficiency.You save the time and space needed to copy a structure or a class design. Make the pointer or reference const.

4. If the data object is a class object, use a const reference.The semantics of class design often require using a reference, which is the main reason C++ added this feature.Thus, the standard way to pass class object arguments is by reference.

A function modifies data in the calling function:

1.If the data object is a built-in data type, use a pointer. If you spot code like fixit(&x), where x is an int, it’s pretty clear that this function intends to modify x.

2.If the data object is an array, use your only choice: a pointer.

3.If the data object is a structure, use a reference or a pointer.

4.If the data object is a class object, use a reference.

Of course, these are just guidelines, and there might be reasons for making different choices. For example, cin uses references for basic types so that you can use cin >> n instead of cin >> &n.

int a[] = { 2, 6, 8, 5, 4, 3 }; 
int b[] = { 2, 3, 4, 7 };

if you take float number then you take float and it's your choice

this is very good way to show array elements.

Add to doc header:

\usepackage{ amssymb }

Then at the desired location add:

Here is my case. I had a remote machine that hosted SQL Server. From my local machine, I was trying to access the SQL instance via some C# code and I was getting this error. My password for the user account on my machine/domain had expired. I fixed it with the following:

1. Opened the remote machine, which prompted me for a password change
2. I changed my password within this prompt and logged into the remote machine
3. I "locked" my local machine (using windows + L key so I didn't have to completely sign off) so that I could get back to the sign-on page
4. I signed back onto my local machine with the new password

Everything then worked fine.

Two options:

char c1 = '\u0001';
char c1 = (char) 1;

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

The below solution worked for me.

1. In the parameter tab of your dataset properties click on the expression icon (!http://chittagongit.com//images/fx-icon/fx-icon-16.jpg [fx symbol]) beside the parameter you need to allow comma delimited entry for.

2. In the expression window that appears, use the Split function (Common Functions -> Text). Example shown below:

=Split(Parameters!ParameterName.Value,",")

Note: Once it happened that I accidentally had a space before my database name such as mydatabase instead of mydatabase, phpmyadmin won't show the space, but if you run it from the command line interface of mysql, such as mysql -u the_user -p then show databases, you'll be able to see the space.

To find duplicate counts use below command as requested by you :

sort filename | uniq -c | awk '{print $2, $1}'

Not exactly like that, but there are workarounds. There's a section in React's docs about conditional rendering that you should take a look. Here's an example of what you could do using inline if-else.

render() {
  const isLoggedIn = this.state.isLoggedIn;
  return (
    <div>
      {isLoggedIn ? (
        <LogoutButton onClick={this.handleLogoutClick} />
      ) : (
        <LoginButton onClick={this.handleLoginClick} />
      )}
    </div>
  );
}

You can also deal with it inside the render function, but before returning the jsx.

if (isLoggedIn) {
  button = <LogoutButton onClick={this.handleLogoutClick} />;
} else {
  button = <LoginButton onClick={this.handleLoginClick} />;
}

return (
  <div>
    <Greeting isLoggedIn={isLoggedIn} />
    {button}
  </div>
);

It's also worth mentioning what ZekeDroid brought up in the comments. If you're just checking for a condition and don't want to render a particular piece of code that doesn't comply, you can use the && operator.

  return (
    <div>
      <h1>Hello!</h1>
      {unreadMessages.length > 0 &&
        <h2>
          You have {unreadMessages.length} unread messages.
        </h2>
      }
    </div>
  );

for converting dd/mm/yyyy to mm/dd/yyyy

=DATE(RIGHT(a1,4),MID(a1,4,2),LEFT(a1,2))

Hazar is right with his \t. Here's the full list of escape characters for C#:

\' for a single quote.

\" for a double quote.

\\ for a backslash.

\0 for a null character.

\a for an alert character.

\b for a backspace.

\f for a form feed.

\n for a new line.

\r for a carriage return.

\t for a horizontal tab.

\v for a vertical tab.

\uxxxx for a unicode character hex value (e.g. \u0020).

\x is the same as \u, but you don't need leading zeroes (e.g. \x20).

\Uxxxxxxxx for a unicode character hex value (longer form needed for generating surrogates).

"cell one","cell "" two","cell "" ,three"

Save this to csv file and see the results, so double quote is used to escape itself

Important Note

"cell one","cell "" two", "cell "" ,three"

will give you a different result because there is a space after the comma, and that will be treated as "

For anyone that is working with a directory style like this:

project
    > src
        > pkgA     
        > pkgB
        ...
    > bin
        > pkgA
        > pkgB
        ...

The following worked very well for me. I made this myself, using the GNU make manual as my main reference; this, in particular, was extremely helpful for my last rule, which ended up being the most important one for me.

My Makefile:

PROG := sim
CC := g++
ODIR := bin
SDIR := src
MAIN_OBJ := main.o
MAIN := main.cpp
PKG_DIRS := $(shell ls $(SDIR))
CXXFLAGS = -std=c++11 -Wall $(addprefix -I$(SDIR)/,$(PKG_DIRS)) -I$(BOOST_ROOT)
FIND_SRC_FILES = $(wildcard $(SDIR)/$(pkg)/*.cpp) 
SRC_FILES = $(foreach pkg,$(PKG_DIRS),$(FIND_SRC_FILES)) 
OBJ_FILES = $(patsubst $(SDIR)/%,$(ODIR)/%,\
$(patsubst %.cpp,%.o,$(filter-out $(SDIR)/main/$(MAIN),$(SRC_FILES))))

vpath %.h $(addprefix $(SDIR)/,$(PKG_DIRS))
vpath %.cpp $(addprefix $(SDIR)/,$(PKG_DIRS)) 
vpath $(MAIN) $(addprefix $(SDIR)/,main)

# main target
#$(PROG) : all
$(PROG) : $(MAIN) $(OBJ_FILES) 
    $(CC) $(CXXFLAGS) -o $(PROG) $(SDIR)/main/$(MAIN) 

# debugging
all : ; $(info $$PKG_DIRS is [${PKG_DIRS}])@echo Hello world

%.o : %.cpp
    $(CC) $(CXXFLAGS) -c $< -o $@

# This one right here, folks. This is the one.
$(OBJ_FILES) : $(ODIR)/%.o : $(SDIR)/%.h
    $(CC) $(CXXFLAGS) -c $< -o $@

# for whatever reason, clean is not being called...
# any ideas why???
.PHONY: clean

clean :
    @echo Build done! Cleaning object files...
    @rm -r $(ODIR)/*/*.o

By using $(SDIR)/%.h as a prerequisite for $(ODIR)/%.o, this forced make to look in source-package directories for source code instead of looking in the same folder as the object file.

I hope this helps some people. Let me know if you see anything wrong with what I've provided.

BTW: As you may see from my last comment, clean is not being called and I am not sure why. Any ideas?

On Firefox, the simplest way is via the menu command View > Page Style > No Style. But this also switches off the effects of some presentational HTML markup. So using plugins as suggested by @JoelKuiper is usually better; they give more flexibility (e.g., switching off just some style sheets).

When you install anaconda on windows now, it doesn't automatically add Python or Conda to your path.

While during the installation process you can check this box, you can also add python and/or python to your path manually (as you can see below the image)

If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt

where python
where conda

Next, you can add Python and Conda to your path by using the setx command in your command prompt (replace C:\Users\mgalarnyk\Anaconda2 with the results you got when running where python and where conda).

SETX PATH "%PATH%;C:\Users\mgalarnyk\Anaconda2\Scripts;C:\Users\mgalarnyk\Anaconda2"

Next close that command prompt and open a new one. Congrats you can now use conda and python

Here are a couple of ways.

The first will order things based on the order seen in the data frame:

x$variable <- factor(x$variable, levels=unique(as.character(x$variable)) )

The second orders the levels based on another variable (value in this case):

x <- transform(x, variable=reorder(variable, -value) )
