Note that in general, Mockito does allow throwing checked exceptions so long as the exception is declared in the message signature. For instance, given

class BarException extends Exception {
  // this is a checked exception
}

interface Foo {
  Bar frob() throws BarException
}

it's legal to write:

Foo foo = mock(Foo.class);
when(foo.frob()).thenThrow(BarException.class)

However, if you throw a checked exception not declared in the method signature, e.g.

class QuxException extends Exception {
  // a different checked exception
}

Foo foo = mock(Foo.class);
when(foo.frob()).thenThrow(QuxException.class)

Mockito will fail at runtime with the somewhat misleading, generic message:

Checked exception is invalid for this method!
Invalid: QuxException

This may lead you to believe that checked exceptions in general are unsupported, but in fact Mockito is only trying to tell you that this checked exception isn't valid for this method.

You need to update the date format:

select * from hockey_stats 
where game_date between '2012-03-11 00:00:00' and '2012-05-11 23:59:00' 
order by game_date desc;

You can just use the .NET Framework method:

[System.Net.Dns]::GetHostName()

also

$env:COMPUTERNAME

It is the directory from where you start the batch file. E.g. if your batch is in c:\dir1\dir2 and you do cd c:\dir3, then run the batch, the current directory will be c:\dir3.

I was having this same issue and it was because I was trying to manipulate elements using javascript in a div that was overflow: scroll, all I did was change overflow to auto and everything worked.

Hope this helps

A lot of *NIX systems also have either or both pkill(1) and killall(1) which, allows you to kill processes by name. Using them, you can avoid the whole parsing ps problem.

Introduction

You can get everything through ExternalContext. In JSF 1.x, you can get the raw HttpServletResponse object by ExternalContext#getResponse(). In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream() without the need to grab the HttpServletResponse from under the JSF hoods.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Most important part is to call FacesContext#responseComplete() to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException with a message like getoutputstream() has already been called for this response when the JSF implementation calls getWriter() to render HTML.

Turn off ajax / don't use remote command!

You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink> and <h:commandButton>. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.

In case you're using e.g. PrimeFaces <p:commandXxx>, then you need to make sure that you explicitly turn off ajax via ajax="false" attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" /> in the command component.

Generic JSF 2.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();

    ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
    ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = ec.getResponseOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Generic JSF 1.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();

    response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
    response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = response.getOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Common static file example

In case you need to stream a static file from the local disk file system, substitute the code as below:

File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();

// ...

Files.copy(file.toPath(), output);

Common dynamic file example

In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output there where the API being used expects an OutputStream.

E.g. iText PDF:

String fileName = "dynamic.pdf";
String contentType = "application/pdf";

// ...

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();

E.g. Apache POI HSSF:

String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";

// ...

HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();

Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.

Utility method

If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile() methods taking either a File, or an InputStream, or a byte[], and specifying whether the file should be downloaded as an attachment (true) or inline (false).

public void download() throws IOException {
    Faces.sendFile(file, true);
}

Yes, this code is complete as-is. You don't need to invoke responseComplete() and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.

Check if you have the linebreak-style rule configure as below either in your .eslintrc or in source code:

/*eslint linebreak-style: ["error", "unix"]*/

Since you're working on Windows, you may want to use this rule instead:

/*eslint linebreak-style: ["error", "windows"]*/

Refer to the documentation of linebreak-style:

When developing with a lot of people all having different editors, VCS applications and operating systems it may occur that different line endings are written by either of the mentioned (might especially happen when using the windows and mac versions of SourceTree together).

The linebreaks (new lines) used in windows operating system are usually carriage returns (CR) followed by a line feed (LF) making it a carriage return line feed (CRLF) whereas Linux and Unix use a simple line feed (LF). The corresponding control sequences are "\n" (for LF) and "\r\n" for (CRLF).

This is a rule that is automatically fixable. The --fix option on the command line automatically fixes problems reported by this rule.

But if you wish to retain CRLF line-endings in your code (as you're working on Windows) do not use the fix option.

You can use this command:

$ dpkg -s libgtk2.0-0|grep '^Version'

RightClick on the Project > Properties > Android > Fix project properties

This solved it for me. easy.

Copy Azure database data to local database: Now you can use the SQL Server Management Studio to do this as below:

• Connect to the SQL Azure database.
• Right click the database in Object Explorer.
• Choose the option "Tasks" / "Deploy Database to SQL Azure".
• In the step named "Deployment Settings", connect local SQL Server and create New database.

"Next" / "Next" / "Finish"

max(may$Ozone, na.rm = TRUE)

Without $Ozone it will filter in the whole data frame, this can be learned in the swirl library.

It is important to note that object files are assembled to binary code in a format that is relocatable. This is a form which allows the assembled code to be loaded anywhere into memory for use with other programs by a linker.

Instructions that refer to labels will not yet have an address assigned for these labels in the .o file.

These labels will be written as '0' and the assembler creates a relocation record for these unknown addresses. When the file is linked and output to an executable the unknown addresses are resolved and the program can be executed.

You can use the nm tool on an object file to list the symbols defined in a .o file.

You can also use:

round(mod(rand.*max,max-1))+min

go to FileZilla and select which folder you will be give 777 permission, then right click set permission 777 and select check box, then ok.

This is probably how you should do it:

void push(std::string&& filename)
{
    {
        std::lock_guard<std::mutex> lock(qMutex);

        q.push(std::move(filename));
    }

    populatedNotifier.notify_one();
}

bool try_pop(std::string& filename, std::chrono::milliseconds timeout)
{
    std::unique_lock<std::mutex> lock(qMutex);

    if(!populatedNotifier.wait_for(lock, timeout, [this] { return !q.empty(); }))
        return false;

    filename = std::move(q.front());
    q.pop();

    return true;    
}

If you want to do it while keeping the user interaction on. In my case I am using (or rather misusing) isFocused

self.myField.inputView = UIView()

This way it will focus but keyboard won't show up.

You don't really need a regex.

printf "%s\n" *[!\ -~]*

This will show file names with control characters in their names, too, but I consider that a feature.

If you don't have any matching files, the glob will expand to just itself, unless you have nullglob set. (The expression does not match itself, so technically, this output is unambiguous.)

create a file named logging.properties in WEB-INF/classes with following content:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

I think of return as a trick. As a general rule, the value of the last expression evaluated in a function becomes the function's value -- and this general pattern is found in many places. All of the following evaluate to 3:

local({
1
2
3
})

eval(expression({
1
2
3
}))

(function() {
1
2
3
})()

What return does is not really returning a value (this is done with or without it) but "breaking out" of the function in an irregular way. In that sense, it is the closest equivalent of GOTO statement in R (there are also break and next). I use return very rarely and never at the end of a function.

 if(a) {
   return(a)
 } else {
   return(b)
 }

... this can be rewritten as if(a) a else b which is much better readable and less curly-bracketish. No need for return at all here. My prototypical case of use of "return" would be something like ...

ugly <- function(species, x, y){
   if(length(species)>1) stop("First argument is too long.")
   if(species=="Mickey Mouse") return("You're kidding!")
   ### do some calculations 
   if(grepl("mouse", species)) {
      ## do some more calculations
      if(species=="Dormouse") return(paste0("You're sleeping until", x+y))
      ## do some more calculations
      return(paste0("You're a mouse and will be eating for ", x^y, " more minutes."))
      }
   ## some more ugly conditions
   # ...
   ### finally
   return("The end")
   }

Generally, the need for many return's suggests that the problem is either ugly or badly structured.

[EDIT]

return doesn't really need a function to work: you can use it to break out of a set of expressions to be evaluated.

getout <- TRUE 
# if getout==TRUE then the value of EXP, LOC, and FUN will be "OUTTA HERE"
# .... if getout==FALSE then it will be `3` for all these variables    

EXP <- eval(expression({
   1
   2
   if(getout) return("OUTTA HERE")
   3
   }))

LOC <- local({
   1
   2
   if(getout) return("OUTTA HERE")
   3
   })

FUN <- (function(){
   1
   2
   if(getout) return("OUTTA HERE")
   3
   })()

identical(EXP,LOC)
identical(EXP,FUN)

LINQ-to-SQL is a remarkable piece of technology that is very simple to use, and by and large generates very good queries to the back end. LINQ-to-EF was slated to supplant it, but historically has been extremely clunky to use and generated far inferior SQL. I don't know the current state of affairs, but Microsoft promised to migrate all the goodness of L2S into L2EF, so maybe it's all better now.

Personally, I have a passionate dislike of ORM tools (see my diatribe here for the details), and so I see no reason to favour L2EF, since L2S gives me all I ever expect to need from a data access layer. In fact, I even think that L2S features such as hand-crafted mappings and inheritance modeling add completely unnecessary complexity. But that's just me. ;-)

I had the same problem, to resolve it, go windows -> preferences -> servers and select runtime environment, and now you will see a new window, in the upper right you will see a option: Download additional server adapter, click and install the glassfish server.

Explicit pass-through

Similar to nesting the callbacks, this technique relies on closures. Yet, the chain stays flat - instead of passing only the latest result, some state object is passed for every step. These state objects accumulate the results of the previous actions, handing down all values that will be needed later again plus the result of the current task.

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(b => [resultA, b]); // function(b) { return [resultA, b] }
    }).then(function([resultA, resultB]) {
        // more processing
        return // something using both resultA and resultB
    });
}

Here, that little arrow b => [resultA, b] is the function that closes over resultA, and passes an array of both results to the next step. Which uses parameter destructuring syntax to break it up in single variables again.

Before destructuring became available with ES6, a nifty helper method called .spread() was pro­vi­ded by many promise libraries (Q, Bluebird, when, …). It takes a function with multiple parameters - one for each array element - to be used as .spread(function(resultA, resultB) { ….

Of course, that closure needed here can be further simplified by some helper functions, e.g.

function addTo(x) {
    // imagine complex `arguments` fiddling or anything that helps usability
    // but you get the idea with this simple one:
    return res => [x, res];
}

…
return promiseB(…).then(addTo(resultA));

Alternatively, you can employ Promise.all to produce the promise for the array:

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return Promise.all([resultA, promiseB(…)]); // resultA will implicitly be wrapped
                                                    // as if passed to Promise.resolve()
    }).then(function([resultA, resultB]) {
        // more processing
        return // something using both resultA and resultB
    });
}

And you might not only use arrays, but arbitrarily complex objects. For example, with _.extend or Object.assign in a different helper function:

function augment(obj, name) {
    return function (res) { var r = Object.assign({}, obj); r[name] = res; return r; };
}

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(augment({resultA}, "resultB"));
    }).then(function(obj) {
        // more processing
        return // something using both obj.resultA and obj.resultB
    });
}

While this pattern guarantees a flat chain and explicit state objects can improve clarity, it will become tedious for a long chain. Especially when you need the state only sporadically, you still have to pass it through every step. With this fixed interface, the single callbacks in the chain are rather tightly coupled and inflexible to change. It makes factoring out single steps harder, and callbacks cannot be supplied directly from other modules - they always need to be wrapped in boilerplate code that cares about the state. Abstract helper functions like the above can ease the pain a bit, but it will always be present.

For WAMP [Windows 7 Ultimate x64-bit] Users:

I agree with what DangerDave said and so I'm making an answer available for WAMP Users.

Note: First of all, you have to go to your ..\WAMP\Bin\MySQL\MySQL[Your MySQL Version]\Data folder.

Now, you'll see folders of all your databases

• Double-click the folder of the database which has the offending table to open it
• There shouldn't be a file [Your offending MySQL table name].frm, instead there should be a file [Your offending MySQL table name].ibd
• Delete the [Your offending MySQL table name].ibd
• Then, delete it from the Recycle Bin too
• Then run your MySQL query on the database and you're done

In order to have this result:

{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}

that holds the same data as:

  {
    "aoColumnDefs": [
     { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
     { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
     { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
   ]
  }

you could use this code:

    JSONObject jo = new JSONObject();
    Collection<JSONObject> items = new ArrayList<JSONObject>();

    JSONObject item1 = new JSONObject();
    item1.put("aDataSort", new JSONArray(0, 1));
    item1.put("aTargets", new JSONArray(0));
    items.add(item1);
    JSONObject item2 = new JSONObject();
    item2.put("aDataSort", new JSONArray(1, 0));
    item2.put("aTargets", new JSONArray(1));
    items.add(item2);
    JSONObject item3 = new JSONObject();
    item3.put("aDataSort", new JSONArray(2, 3, 4));
    item3.put("aTargets", new JSONArray(2));
    items.add(item3);

    jo.put("aoColumnDefs", new JSONArray(items));

    System.out.println(jo.toString());

To trim a string down so it does not contain two or more spaces in a row. Every instance of 2 or more space will be trimmed down to 1 space. A simple solution:

While ImageText1.Contains("  ")                     '2 spaces.
    ImageText1 = ImageText1.Replace("  ", " ")      'Replace with 1 space.
End While

You just use the method

public Object put(Object key, Object value)

if the key was already present in the Map then the previous value is returned.

Go for whatever is most readable and easily maintainable. Just because you can write it out in a single line doesn't mean that you should. Your existing solution is close to what I would use other than I would user iteritems to skip the value lookup, and I hate nested ifs if I can avoid them:

for key, val in d.iteritems():
    if filter_string not in key:
        continue
    # do something

However if you realllly want something to let you iterate through a filtered dict then I would not do the two step process of building the filtered dict and then iterating through it, but instead use a generator, because what is more pythonic (and awesome) than a generator?

First we create our generator, and good design dictates that we make it abstract enough to be reusable:

# The implementation of my generator may look vaguely familiar, no?
def filter_dict(d, filter_string):
    for key, val in d.iteritems():
        if filter_string not in key:
            continue
        yield key, val

And then we can use the generator to solve your problem nice and cleanly with simple, understandable code:

for key, val in filter_dict(d, some_string):
    # do something

In short: generators are awesome.

I use this way to chack that varible is numeric:

v * 1 == v

Simply divide the Variable containing Numbers as a string by 1. PowerShell automatically convert the result to an integer.

$a = 15; $b = 2; $a + $b --> 152

But if you divide it before:

$a/1 + $b/1 --> 17

Try this:

=HYPERLINK("mailto:"&A1, A1)

Replace A1 with your text of email address cell.

Honestly, much as I love sed for appropriate tasks, this is definitely a task for perl -- it's truly more powerful for this kind of one-liners, especially to "write it back to where it comes from" (perl's -i switch does it for you, and optionally also lets you keep the old version around e.g. with a .bak appended, just use -i.bak instead).

perl -i.bak -pe 's/\.jpg|\.png|\.gif/.jpg/

rather than intricate work in sed (if even possible there) or awk...

PowerShell is a very powerful and efficient tool. This is cheating a little, but shelling PowerShell via VBA opens up lots of options

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

By default, SQL Plus treats '&' as a special character that begins a substitution string. This can cause problems when running scripts that happen to include '&' for other reasons:

If you know your script includes (or may include) data containing '&' characters, and you do not want the substitution behaviour as above, then use set define off to switch off the behaviour while running the script:

SQL> set define off
SQL> insert into customers (customer_name) values ('Marks & Spencers Ltd');

1 row created.

SQL> select customer_name from customers;

CUSTOMER_NAME
------------------------------
Marks & Spencers Ltd

You might want to add set define on at the end of the script to restore the default behaviour.

Python 3.4+

Use html.unescape():

import html
print(html.unescape('£682m'))

FYI html.parser.HTMLParser.unescape is deprecated, and was supposed to be removed in 3.5, although it was left in by mistake. It will be removed from the language soon.

Python 2.6-3.3

You can use HTMLParser.unescape() from the standard library:

• For Python 2.6-2.7 it's in HTMLParser
• For Python 3 it's in html.parser

>>> try:
...     # Python 2.6-2.7 
...     from HTMLParser import HTMLParser
... except ImportError:
...     # Python 3
...     from html.parser import HTMLParser
... 
>>> h = HTMLParser()
>>> print(h.unescape('£682m'))
£682m

You can also use the six compatibility library to simplify the import:

>>> from six.moves.html_parser import HTMLParser
>>> h = HTMLParser()
>>> print(h.unescape('£682m'))
£682m

ndarray.tofile() should also work

e.g. if your array is called a:

a.tofile('yourfile.txt',sep=" ",format="%s")

Not sure how to get newline formatting though.

Edit (credit Kevin J. Black's comment here):

Since version 1.5.0, np.tofile() takes an optional parameter newline='\n' to allow multi-line output. https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.savetxt.html

I had the same issue, but I have just figured out that :

• parsing the EditText value in the Oncreate method caused the app to crash because when the app starts, there are no values to parse or maybe the placeholders which are letter.

My code:

package com.example.herodav.volumeapp;

import android.renderscript.Double2;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.*;
import android.widget.*;

import org.w3c.dom.Text;

public class MainActivity extends AppCompatActivity {

    EditText height, length, depth;
    TextView volume;
    double h,l,d,vol;


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

        height = (EditText)findViewById(R.id.h);
        length = (EditText)findViewById(R.id.l);
        depth = (EditText)findViewById(R.id.d);
        volume = (TextView)findViewById(R.id.v);

        Button btn = (Button)findViewById(R.id.btn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                calculateVolume();
                volume.setText("Volume = " + String.valueOf(vol));
            }
        });
    }

    public void calculateVolume(){
        h = Double.parseDouble(height.getText().toString());
        l = Double.parseDouble(length.getText().toString());
        d = Double.parseDouble(depth.getText().toString());
        vol = h*l*d;
    }
}

I ran into this problem that cost me a little time, then remembered that git won't store empty folders. Remember that if you have a folder tree you want stored, put a file in at least the deepest folder of that tree, something like a file called ".gitkeep", just to affect storage by git.

The variable item is a string. An index looks like this:

>>> mystring = 'helloworld'
>>> print mystring[0]
'h'

The above example uses the 0 index of the string to refer to the first character.

Strings can't have string indices (like dictionaries can). So this won't work:

>>> mystring = 'helloworld'
>>> print mystring['stringindex']
TypeError: string indices must be integers

Combined the top answers to create an anonymous object version:

var queryString = HttpUtility2.BuildQueryString(new
{
    key2 = "value2",
    key1 = "value1",
});

That generates this:

key2=value2&key1=value1

Here's the code:

public static class HttpUtility2
{
    public static string BuildQueryString<T>(T obj)
    {
        var queryString = HttpUtility.ParseQueryString(string.Empty);

        foreach (var property in TypeDescriptor.GetProperties(typeof(T)).Cast<PropertyDescriptor>())
        {
            var value = (property.GetValue(obj) ?? "").ToString();
            queryString.Add(property.Name, value);
        }

        return queryString.ToString();
    }
}

Some plugins require one to run as an Administrator and will not load unless one has those credentials active in the shell.

Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.

Here is a tidyverse option that might work depending on the data, and some caveats on its usage:

library(tidyverse)

starting_df %>% 
  rownames_to_column() %>% 
  gather(variable, value, -rowname) %>% 
  spread(rowname, value)

rownames_to_column() is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column() and replace rowname with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths sample data would be:

smiths %>% 
    gather(variable, value, -subject) %>% 
    spread(subject, value)

Using the example starting_df with the tidyverse approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths data will not give that warning because all columns except for subject are doubles.

The earlier answer using as.data.frame(t()) will convert everything to a factor if there are mixed column types unless stringsAsFactors = FALSE is added, whereas the tidyverse option converts everything to a character by default if there are mixed column types.

Just in case someone is interest only in what kind of process created the shared moeries, call

ls -l /dev/shm

It lists the names that are associated with the shared memories - at least on Ubuntu. Usually the names are quite telling.

This is a bit outside the scope of your question, but to avoid any potential confusion for readers who are new to VBA: End and End Sub are not the same. They don't perform the same task.

End puts a stop to ALL code execution and you should almost always use Exit Sub (or Exit Function, respectively).

End halts ALL exectution. While this sounds tempting to do it also clears all global and static variables. (source)

See also the MSDN dox for the End Statement

When executed, the End statement resets allmodule-level variables and all static local variables in allmodules. To preserve the value of these variables, use the Stop statement instead. You can then resume execution while preserving the value of those variables.

Note The End statement stops code execution abruptly, without invoking the Unload, QueryUnload, or Terminate event, or any other Visual Basic code. Code you have placed in the Unload, QueryUnload, and Terminate events offorms andclass modules is not executed. Objects created from class modules are destroyed, files opened using the Open statement are closed, and memory used by your program is freed. Object references held by other programs are invalidated.

Nor is End Sub and Exit Sub the same. End Sub can't be called in the same way Exit Sub can be, because the compiler doesn't allow it.

This again means you have to Exit Sub, which is a perfectly legal operation:

Exit Sub
Immediately exits the Sub procedure in which it appears. Execution continues with the statement following the statement that called the Sub procedure. Exit Sub can be used only inside a Sub procedure.

Additionally, and once you get the feel for how procedures work, obviously, End Sub does not clear any global variables. But it does clear local (Dim'd) variables:

End Sub
Terminates the definition of this procedure.

As of Ansible 2.8, you can just use:

{{ p.User['first_name'] }}

See https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.8.html#jinja-undefined-values

You do it exactly as you showed with this line:

get.setHeader("Content-Type", "application/x-zip");

So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.

http://www.rgraph.net/ is excellent for graph and charts.

Have just started switching over a project to c++11 and came across a perfectly good situation for constexpr which cleans up alternative methods of performing the same operation. The key point here is that you can only place the function into the array size declaration when it is declared constexpr. There are a number of situations where I can see this being very useful moving forward with the area of code that I am involved in.

constexpr size_t GetMaxIPV4StringLength()
{
    return ( sizeof( "255.255.255.255" ) );
}

void SomeIPFunction()
{
    char szIPAddress[ GetMaxIPV4StringLength() ];
    SomeIPGetFunction( szIPAddress );
}

Leaving this here for info,

This error can also be caused if PostgreSQL server is on another machine and is not listening on external interfaces.

To debug this specific problem, you can follow theses steps:

• Look at your postgresql.conf, sudo vim /etc/postgresql/9.3/main/postgresql.conf
• Add this line: listen_addresses = '*'
• Restart the service sudo /etc/init.d/postgresql restart

(Note, the commands above are for ubuntu. Other linux distro or OS may have different path to theses files)

Note: using '*' for listening addresses will listen on all interfaces. If you do '0.0.0.0' then it'll listen for all ipv4 and if you do '::' then it'll listen for all ipv6.

There is a plugin, adampietrasiak/jquery.initialize, which is based on MutationObserver that achieves this simply.

$.initialize(".some-element", function() {
    $(this).css("color", "blue");
});

I believe this would also work:

select count(distinct switch_id)   
  from [email protected]  
 where 
   dealer_name =  'XXXX'    
   and (creation_date BETWEEN add_months(trunc(sysdate,'mm'),-1) and  trunc(sysdate, 'mm'))

It has the advantage of using BETWEEN which is the way the OP used his date selection criteria.

Many of you must be landing here to find a solution for opaque border instead of a transparent one. In that case you can use rgba, where a stands for alpha.

.your_class {
    height: 100px;
    width: 100px;
    margin: 100px;
    border: 10px solid rgba(255,255,255,.5);
}

Demo

Here, you can change the opacity of the border from 0-1

If you simply want a complete transparent border, the best thing to use is transparent, like border: 1px solid transparent;

The light bulb started to come on. Unfortunately, I have not discovered a uniform way to correct the problem, as described below.

I believe that my whole problem centers on my autoresizingMasks. And the reason I have concluded that is the same symptoms exist, with or without a UIWebView. And that symptom is that everything is peachy for Portrait. For Landscape, the bottom-most UIButton pops down behind the TabBar.

For example, on one UIView, I have, from top to bottom:

UIView – both springs set (default case) and no struts

UIScrollView - If I set the two springs, and clear everything else (like the UIView), then the UIButton intrudes on the object immediately above it. If I clear everything, then UIButton is OK, but the stuff at the very top hides behind the StatusBar Setting only the top strut, the UIButton pops down behind the Tab Bar.

UILabel and UIImage next vertically – top strut set, flexible everywhere else

Just to complete the picture for the few that have a UIWebView:

UIWebView - Struts: top, left, right Springs: both

UIButton – nothing set, i.e., flexible everywhere

Although my light bulb is dim, there appears to be hope.

If you really need this you can achieve your goal with help of separate table for sequencing (if you don't mind) and a trigger.

Tables

CREATE TABLE table1_seq
(
  id INT NOT NULL AUTO_INCREMENT PRIMARY KEY
);
CREATE TABLE table1
(
  id VARCHAR(7) NOT NULL PRIMARY KEY DEFAULT '0', name VARCHAR(30)
);

Now the trigger

DELIMITER $$
CREATE TRIGGER tg_table1_insert
BEFORE INSERT ON table1
FOR EACH ROW
BEGIN
  INSERT INTO table1_seq VALUES (NULL);
  SET NEW.id = CONCAT('LHPL', LPAD(LAST_INSERT_ID(), 3, '0'));
END$$
DELIMITER ;

Then you just insert rows to table1

INSERT INTO Table1 (name) 
VALUES ('Jhon'), ('Mark');

And you'll have

|      ID | NAME |
------------------
| LHPL001 | Jhon |
| LHPL002 | Mark |

Here is SQLFiddle demo

def update():
    import time
    while True:
        print 'Hello World!'
        time.sleep(5)

That'll run as a function. The while True: makes it run forever. You can always take it out of the function if you need.

In my case it doesn't work, even with __DIR__ or getcwd() it keeps picking the wrong path, I solved by defining a costant in every file I need with the absolute base path of the project:

if(!defined('THISBASEPATH')){ define('THISBASEPATH', '/mypath/'); }
require_once THISBASEPATH.'cache/crud.php';
/*every other require_once you need*/

I have MAMP with php 5.4.10 and my folder hierarchy is basilar:

q.php 
w.php 
e.php 
r.php 
cache/a.php 
cache/b.php 
setting/a.php 
setting/b.php

....

You can use the curl_error() function to detect if there was some error. For example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $your_url);
curl_setopt($ch, CURLOPT_FAILONERROR, true); // Required for HTTP error codes to be reported via our call to curl_error($ch)
//...
curl_exec($ch);
if (curl_errno($ch)) {
    $error_msg = curl_error($ch);
}
curl_close($ch);

if (isset($error_msg)) {
    // TODO - Handle cURL error accordingly
}

See the description of libcurl error codes here

See the description of PHP curl_errno() function here

There are many ways to update your path. Jun1st answer works great. Another method is to augment your .bash_profile to have:

export PATH="/usr/local/bin:/usr/local/sbin:~/bin:$PATH"

The line above places /usr/local/bin and /usr/local/sbin in front of your $PATH. Once you source your .bash_profile or start a new terminal you can verify your path by echo'ing it out.

$ echo $PATH
/usr/local/bin:/usr/local/sbin:/Users/<your account>/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

Once satisfied with the result running $ brew doctor again should no longer produce your error.

This was supposed to get closer to other databases, and ease migrations. But it's not perfect to me, for instance SQL developer won't display it nicely as a normal SELECT.

I prefer the output of pipeline functions, but they need more boilerplate to code.

Your class shoud look something like this:

class Something {     int[] array; //global array, replace type of course     void function1() {        array = new int[10]; //let say you declare it here that will be 10 integers in size     }     void function2() {        array[0] = 12; //assing value at index 0 to 12.     } } 

That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.

Try:

find . -type f -name '*.*' -exec wc -l {} + 

on the directory/directories in question

The problem is that the 'and' is being treated as an 'or'.

No, the problem is that you are using the XPath != operator and you aren't aware of its "weird" semantics.

Solution:

Just replace the any x != y expressions with a not(x = y) expression.

In your specific case:

Replace:

<xsl:when test="$AccountNumber != '12345' and $Balance != '0'">

with:

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')">

Explanation:

By definition whenever one of the operands of the != operator is a nodeset, then the result of evaluating this operator is true if there is a node in the node-set, whose value isn't equal to the other operand.

So:

 $someNodeSet != $someValue

generally doesn't produce the same result as:

 not($someNodeSet = $someValue)

The latter (by definition) is true exactly when there isn't a node in $someNodeSet whose string value is equal to $someValue.

Lesson to learn:

Never use the != operator, unless you are absolutely sure you know what you are doing.

In my experience, I always just use an external program to generate the graph (mathematica, gnuplot, matlab, etc.) and export the graph as a pdf or eps file. Then I include it into the document with includegraphics.

Usage of formdata in react-native

I have used react-native-image-picker to select photo. In my case after choosing the photp from mobile. I'm storing it's info in component state. After, I'm sending POST request using fetch like below

const profile_pic = {
  name: this.state.formData.profile_pic.fileName,
  type: this.state.formData.profile_pic.type,
  path: this.state.formData.profile_pic.path,
  uri: this.state.formData.profile_pic.uri,
}
const formData = new FormData()
formData.append('first_name', this.state.formData.first_name);
formData.append('last_name', this.state.formData.last_name);
formData.append('profile_pic', profile_pic);
const Token = 'secret'

fetch('http://10.0.2.2:8000/api/profile/', {
    method: "POST",
    headers: {
      Accept: "application/json",
      "Content-Type": "multipart/form-data",
      Authorization: `Token ${Token}`
    },
    body: formData
  })
  .then(response => console.log(response.json()))

After trying many things with no success, I've managed to get SSH access to the server, and import my 80Mb database with a command line, instead of phpMyAdmin. Here is the command:

mysql -u root -p -D mydatabase -o < mydatabase.sql

It's much easier to import big databases, if you are running xammp on windows, the path for mysql.exe is C:\xampp\mysql\bin\mysql.exe

This is a pretty old question, and while looking for Git libraries, I found one that was made this year (2013) called Gittle.

It worked great for me (where the others I tried were flaky), and seems to cover most of the common actions.

Some examples from the README:

from gittle import Gittle

# Clone a repository
repo_path = '/tmp/gittle_bare'
repo_url = 'git://github.com/FriendCode/gittle.git'
repo = Gittle.clone(repo_url, repo_path)

# Stage multiple files
repo.stage(['other1.txt', 'other2.txt'])

# Do the commit
repo.commit(name="Samy Pesse", email="[email protected]", message="This is a commit")

# Authentication with RSA private key
key_file = open('/Users/Me/keys/rsa/private_rsa')
repo.auth(pkey=key_file)

# Do push
repo.push()

In case you have a local variable with the same name, you might want to use the globals() function.

globals()['your_global_var'] = 42

The Run/Debug configuration you're using is meant to let you run Maven on your workspace as if from the command line without leaving Eclipse.

Assuming your tests are JUnit based you should be able to debug them by choosing a source folder containing tests with the right button and choose Debug as... -> JUnit tests.

With Python>3.5, using glob, . pointing to your current folder and looking for .txt files:

 python -c "import glob;[print(x) for x in glob.glob('./**/*txt', recursive=True)]"

For older versions of Python, you can install glob2

I encountered the same situation. And I find out it is because the pip should be updated. It may be the same reason for your problem.

For each iteration of the ng-repeat loop, line is a reference to an object in your array. Therefore, to preview the value, use {{line.text}}.

Similarly, to databind to the text, databind to the same: ng-model="line.text". You don't need to use value when using ng-model (actually you shouldn't).

Fiddle.

For a more in-depth look at scopes and ng-repeat, see What are the nuances of scope prototypal / prototypical inheritance in AngularJS?, section ng-repeat.

Instead of using the body you could create a curtain with z-index of 100 (to pick a number) and give the inside element a higher z-index while all other elements have a lower z-index than the curtain.

See working example here: http://jsfiddle.net/Flandre/6JvFk/

jQuery:

$('#curtain').on("click", function(e) {

    $(this).hide();
    alert("clicked ouside of elements that stand out");

});

CSS:

.aboveCurtain
{
    z-index: 200; /* has to have a higher index than the curtain */
    position: relative;
    background-color: pink;
}

#curtain
{
    position: fixed;
    top: 0px;
    left: 0px;
    height: 100%;
    background-color: black;
    width: 100%;
    z-index:100;   
    opacity:0.5 /* change opacity to 0 to make it a true glass effect */
}

Subject is the certificate's common name and is a critical property for the certificate in a lot of cases if it's a server certificate and clients are looking for a positive identification.

As an example on an SSL certificate for a web site the subject would be the domain name of the web site.

Sometimes the column you are looking for may be part of the name of many other things that you are not interested in.

For example I was recently looking for a column called "BQR", which also forms part of many other columns such as "BQR_OWNER", "PROP_BQR", etc.

So I would like to have the checkbox that word processors have to indicate "Whole words only".

Unfortunately LIKE has no such functionality, but REGEXP_LIKE can help.

SELECT *
  FROM user_source
 WHERE regexp_like(text, '(\s|\.|,|^)bqr(\s|,|$)');

This is the regular expression to find this column and exclude the other columns with "BQR" as part of the name:

(\s|\.|,|^)bqr(\s|,|$)

The regular expression matches white-space (\s), or (|) period (.), or (|) comma (,), or (|) start-of-line (^), followed by "bqr", followed by white-space, comma or end-of-line ($).

As pointed out by Martijn, glob can only do this through the **operator introduced in Python 3.5. Since the OP explicitly asked for the glob module, the following will return a lazy evaluation iterator that behaves similarly

import os, glob, itertools

configfiles = itertools.chain.from_iterable(glob.iglob(os.path.join(root,'*.txt'))
                         for root, dirs, files in os.walk('C:/Users/sam/Desktop/file1/'))

Note that you can only iterate once over configfiles in this approach though. If you require a real list of configfiles that can be used in multiple operations you would have to create this explicitly by using list(configfiles).

• The best would be using s1.equalsIgnoreCase(s2): (see javadoc)
• You can also convert them both to upper/lower case and use s1.equals(s2)

15, 15, 15.5, 15.5

simply I think you are missing a single quote in your code

if ((hr==20)) document.write("Good Night"); document.getElementById('Night"here").style.display=''

it should be like this

if ((hr==20)) document.write("Good Night"); document.getElementById('Night').style.display=''

If you want to style the output of a data frame in a jupyter notebook cell, you can set the display style on a per-dataframe basis:

df = pd.DataFrame({'A': np.random.randn(4)*1e7})
df.style.format("{:.1f}")

See the documentation here.

As already stated ??!??! is essentially two trigraphs (??! and ??! again) mushed together that get replaced-translated to ||, i.e the logical OR, by the preprocessor.

The following table containing every trigraph should help disambiguate alternate trigraph combinations:

Trigraph   Replaces

??(        [
??)        ]
??<        {
??>        }
??/        \
??'        ^
??=        #
??!        |
??-        ~

^{Source: C: A Reference Manual 5th Edition}

So a trigraph that looks like ??(??) will eventually map to [], ??(??)??(??) will get replaced by [][] and so on, you get the idea.

Since trigraphs are substituted during preprocessing you could use cpp to get a view of the output yourself, using a silly trigr.c program:

void main(){ const char *s = "??!??!"; } 

and processing it with:

cpp -trigraphs trigr.c 

You'll get a console output of

void main(){ const char *s = "||"; }

As you can notice, the option -trigraphs must be specified or else cpp will issue a warning; this indicates how trigraphs are a thing of the past and of no modern value other than confusing people who might bump into them.

As for the rationale behind the introduction of trigraphs, it is better understood when looking at the history section of ISO/IEC 646:

ISO/IEC 646 and its predecessor ASCII (ANSI X3.4) largely endorsed existing practice regarding character encodings in the telecommunications industry.

As ASCII did not provide a number of characters needed for languages other than English, a number of national variants were made that substituted some less-used characters with needed ones.

^{(emphasis mine)}

So, in essence, some needed characters (those for which a trigraph exists) were replaced in certain national variants. This leads to the alternate representation using trigraphs comprised of characters that other variants still had around.

Java's Double class has members containing the Min and Max value for the type.

2^-1074 <= x <= (2-2^-52)·2^1023 // where x is the double.

Check out the Min_VALUE and MAX_VALUE static final members of Double.

(some)People will suggest against using floating point types for things where accuracy and precision are critical because rounding errors can throw off calculations by measurable (small) amounts.

By using order separately each subset gets order, but not the whole set, which is what you would want uniting two tables.

You should use something like this to have one ordered set:

SELECT TOP (100) PERCENT field1, field2, field3, field4, field5 FROM 
(SELECT table1.field1, table1.field2, table1.field3, table1.field4, table1.field5 FROM table1
UNION ALL 
SELECT table2.field1, table2.field2, table2.field3, table2.field4, table2.field5 FROM  table2) 
AS unitedTables ORDER BY field5 DESC

a = double.Parse(Console.ReadLine());

Beware that if the user enters something that cannot be parsed to a double, an exception will be thrown.

Edit:

To expand on my answer, the reason it's not working for you is that you are getting an input from the user in string format, and trying to put it directly into a double. You can't do that. You have to extract the double value from the string first.

If you'd like to perform some sort of error checking, simply do this:

if ( double.TryParse(Console.ReadLine(), out a) ) {
  Console.Writeline("Sonuç "+ a * Math.PI;); 
}
else {
  Console.WriteLine("Invalid number entered. Please enter number in format: #.#");
}

If you wish dialog box to be re-activated for the page you set as prevent dialog box to show.

Chrome: select settings, a google page for chrome will open with all your settings for chrome.

At the very bottom, go to advance settings and at the bottom of the advance settings you may click on Resset Browser Settings... this will make dialog box appear as they should.

This method works for everything (integers and even doubles) except zero (it calls it invalid):

The while loop is just for the repetitive user input. Basically it checks if the integer x/x = 1. If it does (as it would with a number), its an integer/double. If it doesn't, it obviously it isn't. Zero fails the test though.

#include <stdio.h> 
#include <math.h>

void main () {
    double x;
    int notDouble;
    int true = 1;
    while(true) {
        printf("Input an integer: \n");
        scanf("%lf", &x);
        if (x/x != 1) {
            notDouble = 1;
            fflush(stdin);
        }
        if (notDouble != 1) {
            printf("Input is valid\n");
        }
        else {
            printf("Input is invalid\n");
        }
        notDouble = 0;
    }
}

You can set RequestParam, using generic class Integer instead of int, it will resolve your issue.

   @RequestParam(value= "i", defaultValue = "20") Integer i

For showing result of batch file in text file, you can use

this command

chdir > test.txt

This command will redirect result to test.txt.

When you open test.txt you will found current path of directory in test.txt

/stop([a-zA-Z])+/

Will match any stop word (stop, stopped, stopping, etc)

However, if you just want to match "stop" at the start of a string

/^stop/

will do :D

This should do what you want:

preg_replace("/[^0-9]/", "",$c);

Stuff them into a map (pseudocode)

map[string -> int] $m
foreach($word in $array)
{
    if(!$m.contains($word))
        $m[$word] = 0;

    $m[$word] += 1;
}

I came up with the solution and posted it on my blog

http://web.archive.org/web/20130310123646/http://onlinemarketingexperts.com.au/2013/01/how-to-permanently-redirect-301-all-404-missing-pages-in-htaccess/

here is the htaccess code also

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L,R=301]

but I posted other solutions on my blog too, it depends what you need really

The JavaScript module pattern uses closures. Its nice pattern allows you to have something alike "public" and "private" variables.

var myNamespace = (function () {

  var myPrivateVar, myPrivateMethod;

  // A private counter variable
  myPrivateVar = 0;

  // A private function which logs any arguments
  myPrivateMethod = function(foo) {
      console.log(foo);
  };

  return {

    // A public variable
    myPublicVar: "foo",

    // A public function utilizing privates
    myPublicFunction: function(bar) {

      // Increment our private counter
      myPrivateVar++;

      // Call our private method using bar
      myPrivateMethod(bar);
    }
  };

})();

I had this issue with Dialogs based on an extended DialogFragment which worked fine on devices running API 26 but failed with API 23. The above strategies didn't work but I resolved the issue by removing the onCreateView method (which had been added by a more recent Android Studio template) from the DialogFragment and creating the dialog in onCreateDialog.

Add a common class to all the div. For example add foo to all the divs.

$('.foo').each(function () {
   $(this).dialog({
    autoOpen: false,
    show: {
      effect: "blind",
      duration: 1000
    },
    hide: {
      effect: "explode",
      duration: 1000
    }
  });
});

This probably isn't the most elegant way to do it, but it gets the job done.

In[1]: import numpy as np

In[2]: import pandas as pd

                       ID

6  00013007854817840018860166

Just replace '/Users/spencerlyon2/Desktop/test.csv' with the path to your file

For Windows, I've created a build.cmd file:

(replace the keystore path and alias)

For Cordova:

@echo off 
set /P spassw="Store Password: " && set /P kpassw="Key Password: " && cordova build android --release -- --keystore=../../local/my.keystore --storePassword=%spassw% --alias=tmpalias --password=%kpassw%

And for Ionic:

@echo off 
set /P spassw="Store Password: " && set /P kpassw="Key Password: " && ionic build --prod && cordova build android --release -- --keystore=../../local/my.keystore --storePassword=%spassw% --alias=tmpalias --password=%kpassw%

Save it in the ptoject's directory, you can double click or open it with cmd.

if (($("#one").length > 0)){
   alert('yes');
}

if (($("#two").length > 0)){
   alert('yes');
}

if (($("#three").length > 0)){
   alert('yes');
}

if (($("#four")).length == 0){
   alert('no');
}

This is what you need :)

Something like:

$db = mysqli_connect("localhost", "user", "password", "database");
$name = $db->mysqli_real_escape_string($name);
$query = 'ALTER TABLE assesment ADD ' . $name . ' TINYINT NOT NULL DEFAULT \'0\'';
if($db->query($query)) {
    echo "It worked";
}

Haven't tested it but should work.

encapsulate all of your js code within a window.onload function. I had a similar issue. Everything is loaded asynchronously in javascript so some parts load quicker than others, including your browser. Putting all of your code inside the onload function will ensure everything your code will need from the browser will be ready to use before attempting to execute.

@RequestMapping(value = "/testonly", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
        @RequestParam(required = false) String parameter1,
        @RequestParam(required = false) String parameter2, 
        BindingResult result, HttpServletRequest request) 
        throws ParseException {

    LONG CODE and SAME LONG CODE with a minor difference
}

if @RequestParam(required = true) then you must pass parameter1,parameter2

Use BindingResult and request them based on your conditions.

The Other way

@RequestMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,  
    two @RequestParam parameters, HttpServletRequest request) throws ParseException {

    myMethod();

}


@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter, 
        BindingResult result) throws ParseException {

    myMethod();

    do here your minor difference
}

private returntype myMethod(){
    LONG CODE
}

Try this to reload your current shell:

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

I had the same problem with Android Studio - adb server version (37) doesn't match this client (39). I fixed by the following solution :

• In Android Studio go to Tools -> Android -> SDK Manager

• In the SDK Tools tab untick Android SDK Platform-Tools, click Apply to uninstall.

• I then renamed the folder Platform-Tools to Platform-ToolsOld

• Then back in the SDK Manager re-tick the Platform-Tools to re-install.

The code snippet in the linked proposed duplicate reads user input.

ECHO A current build of Test Harness exists.
set /p delBuild=Delete preexisting build [y/n]?: 

The user can type as many letters as they want, and it will go into the delBuild variable.

Column names vs Names of Series

I would like to explain a bit what happens behind the scenes.

Dataframes are a set of Series.

Series in turn are an extension of a numpy.array.

numpy.arrays have a property .name.

This is the name of the series. It is seldom that Pandas respects this attribute, but it lingers in places and can be used to hack some Pandas behaviors.

Naming the list of columns

A lot of answers here talks about the df.columns attribute being a list when in fact it is a Series. This means it has a .name attribute.

This is what happens if you decide to fill in the name of the columns Series:

df.columns = ['column_one', 'column_two']
df.columns.names = ['name of the list of columns']
df.index.names = ['name of the index']

name of the list of columns     column_one  column_two
name of the index
0                                    4           1
1                                    5           2
2                                    6           3

Note that the name of the index always comes one column lower.

Artefacts that linger

The .name attribute lingers on sometimes. If you set df.columns = ['one', 'two'] then the df.one.name will be 'one'.

If you set df.one.name = 'three' then df.columns will still give you ['one', 'two'], and df.one.name will give you 'three'.

BUT

pd.DataFrame(df.one) will return

    three
0       1
1       2
2       3

Because Pandas reuses the .name of the already defined Series.

Multi-level column names

Pandas has ways of doing multi-layered column names. There is not so much magic involved, but I wanted to cover this in my answer too since I don't see anyone picking up on this here.

    |one            |
    |one      |two  |
0   |  4      |  1  |
1   |  5      |  2  |
2   |  6      |  3  |

This is easily achievable by setting columns to lists, like this:

df.columns = [['one', 'one'], ['one', 'two']]

This is all perfectly normal. Microsoft added sequences in SQL Server 2012, finally, i might add and changed the way identity keys are generated. Have a look here for some explanation.

If you want to have the old behaviour, you can:

1. use trace flag 272 - this will cause a log record to be generated for each generated identity value. The performance of identity generation may be impacted by turning on this trace flag.
2. use a sequence generator with the NO CACHE setting (http://msdn.microsoft.com/en-us/library/ff878091.aspx)

The best way to do, I think, is to handle it like the MSDN said on http://msdn.microsoft.com/en-us/library/system.windows.forms.control.previewkeydown.aspx

But handle it, how you really need it. My way (in the example below) is to catch every KeyDown ;-)

    /// <summary>
    /// onPreviewKeyDown
    /// </summary>
    /// <param name="e"></param>
    protected override void OnPreviewKeyDown(PreviewKeyDownEventArgs e)
    {
        e.IsInputKey = true;
    }

    /// <summary>
    /// onKeyDown
    /// </summary>
    /// <param name="e"></param>
    protected override void OnKeyDown(KeyEventArgs e)
    {
        Input.SetFlag(e.KeyCode);
        e.Handled = true;
    }

    /// <summary>
    /// onKeyUp
    /// </summary>
    /// <param name="e"></param>
    protected override void OnKeyUp(KeyEventArgs e)
    {
        Input.RemoveFlag(e.KeyCode);
        e.Handled = true;
    }

I've solved this problem by using the search function on Docker's website where '*' is a valid search that returns 200k repositories and then I crawled each invididual page. HTML parsing allows me to extract all the image names on each page.

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

Share and enjoy.

I think it occurs due to the missing of environment variable named HTTPPORT. Just create that environment variable as 8080 will resolve the issue. or replace HTTPPORT as 8080 in the URL.

This is an UIImage extension compatible with Swift 3 and Swift 4 which scales image to given size with an aspect ratio

extension UIImage {

    func scaledImage(withSize size: CGSize) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(size, false, 0.0)
        defer { UIGraphicsEndImageContext() }
        draw(in: CGRect(x: 0.0, y: 0.0, width: size.width, height: size.height))
        return UIGraphicsGetImageFromCurrentImageContext()!
    }

    func scaleImageToFitSize(size: CGSize) -> UIImage {
        let aspect = self.size.width / self.size.height
        if size.width / aspect <= size.height {
            return scaledImage(withSize: CGSize(width: size.width, height: size.width / aspect))
        } else {
            return scaledImage(withSize: CGSize(width: size.height * aspect, height: size.height))
        }
    }

}

Example usage

let image = UIImage(named: "apple")
let scaledImage = image.scaleImageToFitSize(size: CGSize(width: 45.0, height: 45.0))

Add somewhere in body

<div class="hide">
<a href="#" class="list-group-item">
    <table>
        <tr>
            <td><img src=""></td>
            <td><p class="list-group-item-text"></p></td>
        </tr>
    </table>
</a>
</div>

then create css

.hide { display: none; }

and add to your js

$('#output').append( $('.hide').html() );

Since this operator reduces comparisons to an integer expression, it provides the most general purpose way to sort ascending or descending based on multiple columns/attributes.

For example, if I have an array of objects I can do things like this:

# `sort!` modifies array in place, avoids duplicating if it's large...

# Sort by zip code, ascending
my_objects.sort! { |a, b| a.zip <=> b.zip }

# Sort by zip code, descending
my_objects.sort! { |a, b| b.zip <=> a.zip }
# ...same as...
my_objects.sort! { |a, b| -1 * (a.zip <=> b.zip) }

# Sort by last name, then first
my_objects.sort! { |a, b| 2 * (a.last <=> b.last) + (a.first <=> b.first) }

# Sort by zip, then age descending, then last name, then first
# [Notice powers of 2 make it work for > 2 columns.]
my_objects.sort! do |a, b|
      8 * (a.zip   <=> b.zip) +
     -4 * (a.age   <=> b.age) +
      2 * (a.last  <=> b.last) +
          (a.first <=> b.first)
end

This basic pattern can be generalized to sort by any number of columns, in any permutation of ascending/descending on each.

I agree that it is not possible in general.

The only thing CSS3 can do (which helped in my case) is to select elements that have no children:

table td:empty
{
   background-color: white;
}

Or have any children (including text):

table td:not(:empty)
{
   background-color: white;
}

Since the other answers don't talk about the rules in C++11 here's one. From C++11 standard (draft n3337) §5/9 (emphasized the difference):

This pattern is called the usual arithmetic conversions, which are defined as follows:

— If either operand is of scoped enumeration type, no conversions are performed; if the other operand does not have the same type, the expression is ill-formed.

— If either operand is of type long double, the other shall be converted to long double.

— Otherwise, if either operand is double, the other shall be converted to double.

— Otherwise, if either operand is float, the other shall be converted to float.

— Otherwise, the integral promotions shall be performed on both operands. Then the following rules shall be applied to the promoted operands:

— If both operands have the same type, no further conversion is needed.

— Otherwise, if both operands have signed integer types or both have unsigned integer types, the operand with the type of lesser integer conversion rank shall be converted to the type of the operand with greater rank.

— Otherwise, if the operand that has unsigned integer type has rank greater than or equal to the rank of the type of the other operand, the operand with signed integer type shall be converted to the type of the operand with unsigned integer type.

— Otherwise, if the type of the operand with signed integer type can represent all of the values of the type of the operand with unsigned integer type, the operand with unsigned integer type shall be converted to the type of the operand with signed integer type.

— Otherwise, both operands shall be converted to the unsigned integer type corresponding to the type of the operand with signed integer type.

See here for a list that's frequently updated.

Try

L.replaceAll("(\\t|\\r?\\n)+", " ");

Depending on the system a linefeed is either \r\n or just \n.

Here is something that might help you doing it. I managed to do it in two iterations.

 private static IEnumerable<string> GetAllNonEmptyDirectories(string path)
   {
     var directories =
        Directory.EnumerateDirectories(path, "*.*", SearchOption.AllDirectories)
        .ToList();

     var directoryList = 
     (from directory in directories
     let isEmpty = Directory.GetFiles(directory, "*.*", SearchOption.AllDirectories).Length == 0
     where !isEmpty select directory)
     .ToList();

     return directoryList.ToList();
   }

You could address the problem with an X-Macro

You would change your struct definition into:

#define LIST_OF_foo_MEMBERS \
    X(int,id) \
    X(int,route) \
    X(int,backup_route) \
    X(int,current_route)


#define X(type,name) type name;
struct foo {
    LIST_OF_foo_MEMBERS 
};
#undef X

And then you would be able to easily define a flexible function that sets all fields to dont_care.

#define X(type,name) in->name = dont_care;    
void setFooToDontCare(struct foo* in) {
    LIST_OF_foo_MEMBERS 
}
#undef X

Following the discussion here, one could also define a default value in this way:

#define X(name) dont_care,
const struct foo foo_DONT_CARE = { LIST_OF_STRUCT_MEMBERS_foo };
#undef X

Which translates into:

const struct foo foo_DONT_CARE = {dont_care, dont_care, dont_care, dont_care,};

And use it as in hlovdal answer, with the advantage that here maintenance is easier, i.e. changing the number of struct members will automatically update foo_DONT_CARE. Note that the last "spurious" comma is acceptable.

I first learned the concept of X-Macros when I had to address this problem.

It is extremely flexible to new fields being added to the struct. If you have different data types, you could define different dont_care values depending on the data type: from here, you could take inspiration from the function used to print the values in the second example.

If you are ok with an all int struct, then you could omit the data type from LIST_OF_foo_MEMBERS and simply change the X function of the struct definition into #define X(name) int name;

Add , after the print "\n" line

so that it reads print "\n",

In it's simplest form you would use it like:

var html = _.template('<li><%= name %></li>', { name: 'John Smith' });
//html is now '<li>John Smith</li>'   

If you're going to be using a template a few times you'll want to compile it so it's faster:

var template = _.template('<li><%= name %></li>');

var html = [];
for (var key in names) {
    html += template({ name: names[i] });
}

console.log(html.join('')); //Outputs a string of <li> items

I personally prefer the Mustache style syntax. You can adjust the template token markers to use double curly braces:

_.templateSettings.interpolate = /\{\{(.+?)\}\}/g;

var template = _.template('<li>{{ name }}</li>');

I solved it by renaming my function.

Changed

function editForm(value)

to

function editTheForm(value)

Works perfectly.

The solution is to stringify the object before calling setItem on the sessionStorage.

var user = {'name':'John'};
sessionStorage.setItem('user', JSON.stringify(user));
var obj = JSON.parse(sessionStorage.user);

The dynamic keyword is new to C# 4.0, and is used to tell the compiler that a variable's type can change or that it is not known until runtime. Think of it as being able to interact with an Object without having to cast it.

dynamic cust = GetCustomer();
cust.FirstName = "foo"; // works as expected
cust.Process(); // works as expected
cust.MissingMethod(); // No method found!

Notice we did not need to cast nor declare cust as type Customer. Because we declared it dynamic, the runtime takes over and then searches and sets the FirstName property for us. Now, of course, when you are using a dynamic variable, you are giving up compiler type checking. This means the call cust.MissingMethod() will compile and not fail until runtime. The result of this operation is a RuntimeBinderException because MissingMethod is not defined on the Customer class.

The example above shows how dynamic works when calling methods and properties. Another powerful (and potentially dangerous) feature is being able to reuse variables for different types of data. I'm sure the Python, Ruby, and Perl programmers out there can think of a million ways to take advantage of this, but I've been using C# so long that it just feels "wrong" to me.

dynamic foo = 123;
foo = "bar";

OK, so you most likely will not be writing code like the above very often. There may be times, however, when variable reuse can come in handy or clean up a dirty piece of legacy code. One simple case I run into often is constantly having to cast between decimal and double.

decimal foo = GetDecimalValue();
foo = foo / 2.5; // Does not compile
foo = Math.Sqrt(foo); // Does not compile
string bar = foo.ToString("c");

The second line does not compile because 2.5 is typed as a double and line 3 does not compile because Math.Sqrt expects a double. Obviously, all you have to do is cast and/or change your variable type, but there may be situations where dynamic makes sense to use.

dynamic foo = GetDecimalValue(); // still returns a decimal
foo = foo / 2.5; // The runtime takes care of this for us
foo = Math.Sqrt(foo); // Again, the DLR works its magic
string bar = foo.ToString("c");

You can update the fragment in two different ways,

First way

like @Sajmon

You need to implement getItemPosition(Object obj) method.

This method is called when you call

notifyDataSetChanged()

You can find a example in Github and more information in this post.

Second way

My approach to update fragments within the viewpager is to use the setTag() method for any instantiated view in the instantiateItem() method. So when you want to change the data or invalidate the view that you need, you can call the findViewWithTag() method on the ViewPager to retrieve the previously instantiated view and modify/use it as you want without having to delete/create a new view each time you want to update some value.

@Override
public Object instantiateItem(ViewGroup container, int position) {
    Object object = super.instantiateItem(container, position);
    if (object instanceof Fragment) {
        Fragment fragment = (Fragment) object;
        String tag = fragment.getTag();
        mFragmentTags.put(position, tag);
    }
    return object;
}

public Fragment getFragment(int position) {
    Fragment fragment = null;
    String tag = mFragmentTags.get(position);
    if (tag != null) {
        fragment = mFragmentManager.findFragmentByTag(tag);
    }
    return fragment;
}

You can find a example in Github or more information in this post:

The corners are actually in .modal-content

So you may try this:

.modal-content {
  background-color: #0480be;
}
.modal-body {
  background-color: #fff;
}

If you change the color of the header or footer, the rounded corners will be drawn over.

As @Pascal said, it is likely that you encounter problem with the firewall or/and proxy issue. As a first step, go through FAQ on the CRAN web page. After that, try to flag R with --internet2.

Sometimes it could be useful to check global options in R studio and uncheck "Use Internet Explorer library/proxy for HTTP". Tools -> Global Options -> Packages and unchecking the "Use Internet Explorer library/proxy for HTTP" option.

Hope this helps.

String value = "somestring";
String lastTwo = null;
if (value != null && value.length() >= 2) {  
    lastTwo = value.substring(value.length() - 2);
}

this way is right with me:

private void textboxNumberic_KeyPress(object sender, KeyPressEventArgs e)
{
     const char Delete = (char)8;
     e.Handled = !Char.IsDigit(e.KeyChar) && e.KeyChar != Delete;
}

Use this code with a closure (introduced in PHP 5.3), it's a bit faster than the accepted answer and for me, the intention to cast it to an integer, is clearer:

// if you have your values in the format '1,2,3,4', use this before:
// $stringArray = explode(',', '1,2,3,4');

$stringArray = ['1', '2', '3', '4'];

$intArray = array_map(
    function($value) { return (int)$value; },
    $stringArray
);

var_dump($intArray);

Output will be:

array(4) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(4)
}

Using Script Console.

In case the jobs are grouped it's possible to either give it a full name with forward slashes:

getItemByFullName("folder_name/job_name") 
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1
job.save()

or traverse the hierarchy like this:

def folder = Jenkins.instance.getItem("folder_name")
def job = folder.getItem("job_name")
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1
job.save()

As Darin says, you can read from the input stream - but I'd avoid relying on all the data being available in a single go. If you're using .NET 4 this is simple:

MemoryStream target = new MemoryStream();
model.File.InputStream.CopyTo(target);
byte[] data = target.ToArray();

It's easy enough to write the equivalent of CopyTo in .NET 3.5 if you want. The important part is that you read from HttpPostedFileBase.InputStream.

For efficient purposes you could check whether the stream returned is already a MemoryStream:

byte[] data;
using (Stream inputStream = model.File.InputStream)
{
    MemoryStream memoryStream = inputStream as MemoryStream;
    if (memoryStream == null)
    {
        memoryStream = new MemoryStream();
        inputStream.CopyTo(memoryStream);
    }
    data = memoryStream.ToArray();
}

Problems

There are some possible cases why the error occurs:

1. Because textBox1.Text contains only number, but the number is too big/too small

2. Because textBox1.Text contains:

   • a) non-number (except space in the beginning/end, - in the beginning) and/or
   • b) thousand separators in the applied culture for your code without specifying NumberStyles.AllowThousands or you specify NumberStyles.AllowThousands but put wrong thousand separator in the culture and/or
   • c) decimal separator (which should not exist in int parsing)

NOT OK Examples:

Case 1

a = Int32.Parse("5000000000"); //5 billions, too large
b = Int32.Parse("-5000000000"); //-5 billions, too small
//The limit for int (32-bit integer) is only from -2,147,483,648 to 2,147,483,647

Case 2 a)

a = Int32.Parse("a189"); //having a 
a = Int32.Parse("1-89"); //having - but not in the beginning
a = Int32.Parse("18 9"); //having space, but not in the beginning or end

Case 2 b)

NumberStyles styles = NumberStyles.AllowThousands;
a = Int32.Parse("1,189"); //not OK, no NumberStyles.AllowThousands
b = Int32.Parse("1,189", styles, new CultureInfo("fr-FR")); //not OK, having NumberStyles.AllowThousands but the culture specified use different thousand separator

Case 2 c)

NumberStyles styles = NumberStyles.AllowDecimalPoint;
a = Int32.Parse("1.189", styles); //wrong, int parse cannot parse decimal point at all!

Seemingly NOT OK, but actually OK Examples:

Case 2 a) OK

a = Int32.Parse("-189"); //having - but in the beginning
b = Int32.Parse(" 189 "); //having space, but in the beginning or end

Case 2 b) OK

NumberStyles styles = NumberStyles.AllowThousands;
a = Int32.Parse("1,189", styles); //ok, having NumberStyles.AllowThousands in the correct culture
b = Int32.Parse("1 189", styles, new CultureInfo("fr-FR")); //ok, having NumberStyles.AllowThousands and correct thousand separator is used for "fr-FR" culture

Solutions

In all cases, please check the value of textBox1.Text with your Visual Studio debugger and make sure that it has purely-acceptable numerical format for int range. Something like this:

1234

Also, you may consider of

1. using TryParse instead of Parse to ensure that the non-parsed number does not cause you exception problem.

2. check the result of TryParse and handle it if not true

   int val;
   bool result = int.TryParse(textbox1.Text, out val);
   if (!result)
       return; //something has gone wrong
   //OK, continue using val
   

It is possible to parse dynamic values in a couple of way.

Interpolation with double-curly braces:

ng-style="{'background-image':'url({{myBackgroundUrl}})'}"

String concatenation:

ng-style="{'background-image': 'url(' + myBackgroundUrl + ')'}"

ES6 template literals:

ng-style="{'background-image': `url(${myBackgroundUrl})`}"

Below are provided steps to fix your issue.

1. Open your IIS
2. Go to "Sites" option.
3. Mouse right click.
4. Then open property "Manage Web Site".
5. Then click on "Advance Settings".
6. Expand section "Connection Limits", here you can set your "connection time out"

Complete copy&paste recipe, just adding the commands in the comments (for the copy-paste solution), after testing them:

git filter-branch --tree-filter 'rm -rf node_modules' --prune-empty HEAD
echo node_modules/ >> .gitignore
git add .gitignore
git commit -m 'Removing node_modules from git history'
git gc
git push origin master --force

After this, you can remove the line "node_modules/" from .gitignore

I want to select the distinct values from one column 'GrondOfLucht' but they should be sorted in the order as given in the column 'sortering'. I cannot get the distinct values of just one column using

Select distinct GrondOfLucht,sortering
from CorWijzeVanAanleg
order by sortering

It will also give the column 'sortering' and because 'GrondOfLucht' AND 'sortering' is not unique, the result will be ALL rows.

use the GROUP to select the records of 'GrondOfLucht' in the order given by 'sortering

SELECT        GrondOfLucht
FROM            dbo.CorWijzeVanAanleg
GROUP BY GrondOfLucht, sortering
ORDER BY MIN(sortering)

Use setItem and getItem if you want to write simple strings to localStorage. Also you should be using text() if it's the text you're after as you say, else you will get the full HTML as a string.

Sample using .text()

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// alert the value to check if we got it
alert(localStorage.getItem('test'));

JSFiddle: https://jsfiddle.net/f3zLa3zc/

Storing the HTML itself

// get html
var html = $('#test')[0].outerHTML;

// set localstorage
localStorage.setItem('htmltest', html);

// test if it works
alert(localStorage.getItem('htmltest'));

JSFiddle:
https://jsfiddle.net/psfL82q3/1/

Update on user comment

A user want to update the localStorage when the div's content changes. Since it's unclear how the div contents changes (ajax, other method?) contenteditable and blur() is used to change the contents of the div and overwrite the old localStorage entry.

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// bind text to 'blur' event for div
$('#test').on('blur', function() {

    // check the new text
    var newText = $(this).text();

    // overwrite the old text
    localStorage.setItem('test', newText);

    // test if it works
    alert(localStorage.getItem('test'));

});

If we were using ajax we would instead trigger the function it via the function responsible for updating the contents.

You'll have to use a favicon for your page. put this in the head-tag: <link rel="shortcut icon" href="/favicon.png" type="image/png">

where favicon.png is preferably a 16x16 png image.

If you are debugging or similar - In chrome developer tools, you can simply use

$x('/html/.//div[@id="text"]')

You can use $(":disabled") to select all disabled items in the current context.

To determine whether a single item is disabled you can use $("#textbox1").is(":disabled").

It can easily be done if u had declared a class that extends from Application

This class will be like a singleton, so when u need a context u can get it just like this:

I think this is the better answer and the cleaner

Here is my code from Utilities package:

 public static String getAppNAme(){
     return MyOwnApplication.getInstance().getString(R.string.app_name);
 }

try like this

if (!(a | b)) {
    //blahblah
}

It's same with

if (a | b) {}
else {
    // blahblah
}

What you are trying to do is not possible. The reason for this is that in a POSIX system (Linux, OSX, etc), a child process cannot modify the environment of a parent process. This includes modifying the parent process's working directory and environment variables.

When you are on the commandline and you go to execute your Node script, your current process (bash, zsh, whatever) spawns a new process which has it's own environment, typically a copy of your current environment (it is possible to change this via system calls; but that's beyond the scope of this reply), allowing that process to do whatever it needs to do in complete isolation. When the subprocess exits, control is handed back to your shell's process, where the environment hasn't been affected.

There are a lot of reasons for this, but for one, imagine that you executed a script in the background (via ./foo.js &) and as it ran, it started changing your working directory or overriding your PATH. That would be a nightmare.

If you need to perform some actions that require changing your working directory of your shell, you'll need to write a function in your shell. For example, if you're running Bash, you could put this in your ~/.bash_profile:

do_cool_thing() {
  cd "/Users"
  echo "Hey, I'm in $PWD"
}

and then this cool thing is doable:

$ pwd
/Users/spike
$ do_cool_thing
Hey, I'm in /Users
$ pwd
/Users

If you need to do more complex things in addition, you could always call out to your nodejs script from that function.

This is the only way you can accomplish what you're trying to do.

Have you tried line-height? It won't solve your problems if there are multiple row labels, but it can be a quick solution.

react-scripts is not recognized as an internal or external command is related to npm.

I would update all of my dependencies in my package.json files to the latest versions in both the main directory and client directory if applicable. You can do this by using an asterisk "*" instead of specifying a specific version number in your package.json files for your dependencies.

For Example:

"dependencies": {
    "body-parser": "*",
    "express": "*",
    "mongoose": "*",
    "react": "*",
    "react-dom": "*",
    "react-final-form": "*",
    "react-final-form-listeners": "*",
    "react-mapbox-gl": "*",
    "react-redux": "*",
    "react-responsive-modal": "*",
  }

I would then make sure any package-lock.json were deleted and then run npm install and yarn install in both the main directory and the client directory as well if applicable.

You should then be able to run a yarn build and then use yarn start to run the application.

app.use() acts as a middleware in express apps. Unlike app.get() and app.post() or so, you actually can use app.use() without specifying the request URL. In such a case what it does is, it gets executed every time no matter what URL's been hit.

The exception that is thrown when the operating system denies access because of an I/O error or a specific type of security error.

you need to use the following attribute and enclose it within the linear layout

<LinearLayout ...>
<scrollView ...> 

</scrollView>
</LinearLayout>

At least in .NET 4.5+ you can also do:

var uri = new System.Uri("C:\\foo", UriKind.Absolute);

You can read your BufferedInputStream like this. It will read data till it reaches end of stream which is indicated by -1.

inputS = new BufferedInputStream(inBS);
byte[] buffer = new byte[1024];    //If you handle larger data use a bigger buffer size
int read;
while((read = inputS.read(buffer)) != -1) {
    System.out.println(read);
    // Your code to handle the data
}

Note that this isn't perfect, since if you had something like, say, <a title=">"> it would break. However, it's about the closest you'd get in non-library Python without a really complex function:

import re

TAG_RE = re.compile(r'<[^>]+>')

def remove_tags(text):
    return TAG_RE.sub('', text)

However, as lvc mentions xml.etree is available in the Python Standard Library, so you could probably just adapt it to serve like your existing lxml version:

def remove_tags(text):
    return ''.join(xml.etree.ElementTree.fromstring(text).itertext())

Also, from API level 21 this is possible:

int random = ThreadLocalRandom.current().nextInt(min, max);

you need to add a handler to the form submit event. In the handler you need to check for each text field, select element and password fields if there values are non empty.

$('form').submit(function() {
     var res = true;
     // here I am checking for textFields, password fields, and any 
     // drop down you may have in the form
     $("input[type='text'],select,input[type='password']",this).each(function() {
         if($(this).val().trim() == "") {
             res = false; 
         }
     })
     return res; // returning false will prevent the form from submitting.
});

After having tried for over two hours, I can safely say that all the method mentioned so far don't work across browsers, or for IE even across browser versions...

For example (top upvoted answer):

 filter:  progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083);  /* IE6,IE7 */
     -ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083)"; /* IE8 */

rotates twice in IE9, once for filter, and once for -ms-filter, so...

All other mentioned methods do not work either, at least not if you have to set no fixed height/width of the table header cell (with background color), where it should automatically adjust to size of the highest element.

because it works on the development server, then you are sorely mistaken to assume the very same code wouldn't throw a Generic GDI+ exception if you deploy it to a Windows 2003 IIS 6 server...

then use it like this:

<img alt="bla" src="GenerateImage.ashx?no_cache=123&text=Hello%20World&rotate=true" />

On Linux you can mount other directories instead of symlinking them

mount --bind olddir newdir

I don't know if something similar is available for other OSes. I also tried using Samba to share a folder and remount it into the Docker context which worked as well.

I also had the error message "TypeError: cannot concatenate 'str' and 'int' objects". It turns out that I only just forgot to add str() around a variable when printing it. Here is my code:

def main():_x000D_
 rolling = True; import random_x000D_
 while rolling:_x000D_
  roll = input("ENTER = roll; Q = quit ")_x000D_
  if roll.lower() != 'q':_x000D_
   num = (random.randint(1,6))_x000D_
   print("----------------------"); print("you rolled " + str(num))_x000D_
  else:_x000D_
   rolling = False_x000D_
main()

I know, it was a stupid mistake but for beginners who are very new to python such as myself, it happens.

According to the book PHP and MySQL for Dynamic Web Sites (4th edition)

Example:

$r = mysqli_query($dbc, $q);

For simple queries like INSERT, UPDATE, DELETE, etc. (which do not return records), the $r variable—short for result—will be either TRUE or FALSE, depending upon whether the query executed successfully.

Keep in mind that “executed successfully” means that it ran without error; it doesn’t mean that the query’s execution necessarily had the desired result; you’ll need to test for that.

Then how to test?

While the mysqli_num_rows() function will return the number of rows generated by a SELECT query, mysqli_affected_rows() returns the number of rows affected by an INSERT, UPDATE, or DELETE query. It’s used like so:

$num = mysqli_affected_rows($dbc);

Unlike mysqli_num_rows(), the one argument the function takes is the database connection ($dbc), not the results of the previous query ($r).

Below code will provide you with all the click events on given selector:

jQuery(selector).data('events').click

You can iterate over it using each or for ex. check the length for validation like:

jQuery(selector).data('events').click.length

Thought it would help someone. :)

StandardScaler performs the task of Standardization. Usually a dataset contains variables that are different in scale. For e.g. an Employee dataset will contain AGE column with values on scale 20-70 and SALARY column with values on scale 10000-80000.
As these two columns are different in scale, they are Standardized to have common scale while building machine learning model.

There is another way to draw a circle - draw it in fragment shader. Create a quad:

float right = 0.5;
float bottom = -0.5;
float left = -0.5;
float top = 0.5;
float quad[20] = {
    //x, y, z, lx, ly
    right, bottom, 0, 1.0, -1.0,
    right, top, 0, 1.0, 1.0,
    left, top, 0, -1.0, 1.0,
    left, bottom, 0, -1.0, -1.0,
};

Bind VBO:

unsigned int glBuffer;
glGenBuffers(1, &glBuffer);
glBindBuffer(GL_ARRAY_BUFFER, glBuffer);
glBufferData(GL_ARRAY_BUFFER, sizeof(float)*20, quad, GL_STATIC_DRAW);

and draw:

#define BUFFER_OFFSET(i) ((char *)NULL + (i))
glEnableVertexAttribArray(ATTRIB_VERTEX);
glEnableVertexAttribArray(ATTRIB_VALUE);
glVertexAttribPointer(ATTRIB_VERTEX , 3, GL_FLOAT, GL_FALSE, 20, 0);
glVertexAttribPointer(ATTRIB_VALUE , 2, GL_FLOAT, GL_FALSE, 20, BUFFER_OFFSET(12));
glDrawArrays(GL_TRIANGLE_FAN, 0, 4);

Vertex shader

attribute vec2 value;
uniform mat4 viewMatrix;
uniform mat4 projectionMatrix;
varying vec2 val;
void main() {
    val = value;
    gl_Position = projectionMatrix*viewMatrix*vertex;
}

Fragment shader

varying vec2 val;
void main() {
    float R = 1.0;
    float R2 = 0.5;
    float dist = sqrt(dot(val,val));
    if (dist >= R || dist <= R2) {
        discard;
    }
    float sm = smoothstep(R,R-0.01,dist);
    float sm2 = smoothstep(R2,R2+0.01,dist);
    float alpha = sm*sm2;
    gl_FragColor = vec4(0.0, 0.0, 1.0, alpha);
}

Don't forget to enable alpha blending:

glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);

For Debian

add

non-free contrib

to deb and deb-src in /etc/apt/sources.list ie:

deb http://ftp.debian.org/debian/ squeeze main non-free contrib
deb-src http://ftp.debian.org/debian/ squeeze main non-free contrib

Then

apt-get update
apt-get install msttcorefonts

Of course you'll need to restart jasperserver. ie:

/opt/jasperreports-server-cp-4.5.0/ctlscript.sh restart

Change for your version / path.

Swift 5+

extension Date {
    
    func get(_ type: Calendar.Component)-> String {
        let calendar = Calendar.current
        let t = calendar.component(type, from: self)
        return (t < 10 ? "0\(t)" : t.description)
    }
}

Usage:

print(Date().get(.year)) // => 2020
print(Date().get(.month)) // => 08
print(Date().get(.day)) // => 18 

You may want to check out my library called DCKit. It's written on the latest version of Swift.

You can just split the string..

public String[] split(String regex)

Note that java.lang.String.split uses delimiter's regular expression value. Basically like this...

String filename = "abc.def.ghi";     // full file name
String[] parts = filename.split("\\."); // String array, each element is text between dots

String beforeFirstDot = parts[0];    // Text before the first dot

Of course, this is split into multiple lines for clairity. It could be written as

String beforeFirstDot = filename.split("\\.")[0];

For anyone that is looking for an easy solution in Visual Studio Community 2019, Fine Code Coverage is simple but it works well.

It cannot give accurate numbers on the precise coverage, but it will tell which lines are being covered with green/red gutters.

yes is possible to run your android emulator without have a hardware accelerator. In fact to do that, you need to open your android virtual device. When you reached to system image configure, it suggest you which version of android image you want to use. Whatever version of android system image that you select,you need to make sure that,ABI is armeabi-v7a and, you target is System image ameabi-v7a with google APIs. And then complete the rest of task and check out your emulator.

I'm going to give you an example of how I read REST headers for my controllers. My controllers only accept application/json as a request type if I have data that needs to be read. I suspect that your problem is that you have an application/octet-stream that Spring doesn't know how to handle.

Normally my controllers look like this:

@Controller
public class FooController {
    @Autowired
    private DataService dataService;

    @RequestMapping(value="/foo/", method = RequestMethod.GET)
    @ResponseBody
    public ResponseEntity<Data> getData(@RequestHeader String dataId){
        return ResponseEntity.newInstance(dataService.getData(dataId);
    }

Now there is a lot of code doing stuff in the background here so I will break it down for you.

ResponseEntity is a custom object that every controller returns. It contains a static factory allowing the creation of new instances. My Data Service is a standard service class.

The magic happens behind the scenes, because you are working with JSON, you need to tell Spring to use Jackson to map HttpRequest objects so that it knows what you are dealing with.

You do this by specifying this inside your <mvc:annotation-driven> block of your config

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper" ref="objectMapper" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

ObjectMapper is simply an extension of com.fasterxml.jackson.databind.ObjectMapper and is what Jackson uses to actually map your request from JSON into an object.

I suspect you are getting your exception because you haven't specified a mapper that can read an Octet-Stream into an object, or something that Spring can handle. If you are trying to do a file upload, that is something else entirely.

So my request that gets sent to my controller looks something like this simply has an extra header called dataId.

If you wanted to change that to a request parameter and use @RequestParam String dataId to read the ID out of the request your request would look similar to this:

contactId : {"fooId"} 

This request parameter can be as complex as you like. You can serialize an entire object into JSON, send it as a request parameter and Spring will serialize it (using Jackson) back into a Java Object ready for you to use.

Example In Controller:

@RequestMapping(value = "/penguin Details/", method = RequestMethod.GET)
@ResponseBody
public DataProcessingResponseDTO<Pengin> getPenguinDetailsFromList(

which gets automatically serialized back into an DataProcessingRequestDTO object before being given to the controller ready for me to use.

As you can see, this is quite powerful allowing you to serialize your data from JSON to an object without having to write a single line of code. You can do this for @RequestParam and @RequestBody which allows you to access JSON inside your parameters or request body respectively.

Now that you have a concrete example to go off, you shouldn't have any problems once you change your request type to application/json.

Also, change this:

    SelBranchVal = SelBranchVal + "," + InvForm.SelBranch[x].value;

to

    SelBranchVal = SelBranchVal + InvForm.SelBranch[x].value+ "," ;

The reason is that for the first time the variable SelBranchVal will be empty

This is the shortest way I've found (needs jQuery1.6+)

HTML:

<input type="checkbox" id="checkAll"/>

JS:

$("#checkAll").change(function () {
    $("input:checkbox").prop('checked', $(this).prop("checked"));
});

I'm using .prop as .attr doesn't work for checkboxes in jQuery 1.6+ unless you've explicitly added a checked attribute to your input tag.

Example-

$("#checkAll").change(function () {_x000D_
    $("input:checkbox").prop('checked', $(this).prop("checked"));_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<form action="#">_x000D_
    <p><label><input type="checkbox" id="checkAll"/> Check all</label></p>_x000D_
    _x000D_
    <fieldset>_x000D_
        <legend>Loads of checkboxes</legend>_x000D_
        <p><label><input type="checkbox" /> Option 1</label></p>_x000D_
        <p><label><input type="checkbox" /> Option 2</label></p>_x000D_
        <p><label><input type="checkbox" /> Option 3</label></p>_x000D_
        <p><label><input type="checkbox" /> Option 4</label></p>_x000D_
    </fieldset>_x000D_
</form>

A common circumstance to use LinkedList is like this:

Suppose you want to remove many certain strings from a list of strings with a large size, say 100,000. The strings to remove can be looked up in HashSet dic, and the list of strings is believed to contain between 30,000 to 60,000 such strings to remove.

Then what's the best type of List for storing the 100,000 Strings? The answer is LinkedList. If the they are stored in an ArrayList, then iterating over it and removing matched Strings whould take up to billions of operations, while it takes just around 100,000 operations by using an iterator and the remove() method.

LinkedList<String> strings = readStrings();
HashSet<String> dic = readDic();
Iterator<String> iterator = strings.iterator();
while (iterator.hasNext()){
    String string = iterator.next();
    if (dic.contains(string))
    iterator.remove();
}

Adding another point of view to above mentioned solutions.

Implicit Wait: When created, is alive until the WebDriver object dies. And is like common for all operations.

Whereas,
Explicit wait, can be declared for a particular operation depending upon the webElement behavior. It has the benefit of customizing the polling time and satisfaction of the condition.
For example, we declared implicit Wait of 10 secs but an element takes more than that, say 20 seconds and sometimes may appears on 5 secs, so in this scenario, Explicit wait is declared.
