Although I'm not answering the original question concering the no-op command, many (if not most) problems when one may think "in this branch I have to do nothing" can be bypassed by simply restructuring the logic so that this branch won't occur.

I try to give a general rule by using the OPs example

do nothing when $a is greater than "10", print "1" if $a is less than "5", otherwise, print "2"

we have to avoid a branch where $a gets more than 10, so $a < 10 as a general condition can be applied to every other, following condition.

In general terms, when you say do nothing when X, then rephrase it as avoid a branch where X. Usually you can make the avoidance happen by simply negating X and applying it to all other conditions.

So the OPs example with the rule applied may be restructured as:

if [ "$a" -lt 10 ] && [ "$a" -le 5 ]
then
    echo "1"
elif [ "$a" -lt 10 ]
then
    echo "2"
fi

Just a variation of the above, enclosing everything in the $a < 10 condition:

if [ "$a" -lt 10 ]
then
    if [ "$a" -le 5 ]
    then
        echo "1"
    else
        echo "2"
    fi
fi

(For this specific example @Flimzys restructuring is certainly better, but I wanted to give a general rule for all the people searching how to do nothing.)

start all daemons and run the command as "hadoop namenode -recover -force" stop the daemons and start again.. wait some time to recover data.

First of all, you're not leveraging the advantage of using a PreparedStatement. I would first suggest that you modify your PreparedStatement as follows:

PreparedStatement statement = con.prepareStatement("select * from orders where status=? AND date=?")

You can then use statement.setXX(param_index, param_value) to set the respective values. For conversion to timestamp, have a look at the following javadocs:

PreparedStatement.setTimeStamp()
Timestamp

Hope this helps!

None of these answers solved my problem, which was that the items weren't the same width in my makeshift flexbox table when it was shrunk to a width too small.

The solution for me was simply to put overflow: hidden; on the flex-grow: 1; cells.

As an alternate method, if you know that there are no spaces in your data, which it seems is the case, you can use split() (with no arguments). This splits on white space and uses a more efficient algorithm than the other version of split. It also strips whitespace from both ends.

line = line.split()

And that's it.

If you can link to a C library, you can use libenca. See http://cihar.com/software/enca/. From the man page:

Enca reads given text files, or standard input when none are given, and uses knowledge about their language (must be supported by you) and a mixture of parsing, statistical analysis, guessing and black magic to determine their encodings.

It's GPL v2.

Just compare the column with that value:

In [9]: df = pandas.DataFrame([1,2,3,4], columns=["data"])

In [10]: df
Out[10]: 
   data
0     1
1     2
2     3
3     4

In [11]: df["desired"] = df["data"] > 2.5
In [11]: df
Out[12]: 
   data desired
0     1   False
1     2   False
2     3    True
3     4    True

Use git fetch && git checkout RemoteBranchName.

It works very well for me...

Using table-layout: fixed as a property for table and width: calc(100%/3); for td (assuming there are 3 td's). With these two properties set, the table cells will be equal in size.

Refer to the demo.

You just need a binary (with debugging symbols included) that is identical to the one that generated the core dump file. Then you can run gdb path/to/the/binary path/to/the/core/dump/file to debug it.

When it starts up, you can use bt (for backtrace) to get a stack trace from the time of the crash. In the backtrace, each function invocation is given a number. You can use frame number (replacing number with the corresponding number in the stack trace) to select a particular stack frame.

You can then use list to see code around that function, and info locals to see the local variables. You can also use print name_of_variable (replacing "name_of_variable" with a variable name) to see its value.

Typing help within GDB will give you a prompt that will let you see additional commands.

npm ws was the answer for me. I found it less intrusive and more straight forward. With it was also trivial to mix websockets with rest services. Shared simple code on this post.

var WebSocketServer = require("ws").Server;
var http = require("http");
var express = require("express");
var port = process.env.PORT || 5000;

var app = express();
    app.use(express.static(__dirname+ "/../"));
    app.get('/someGetRequest', function(req, res, next) {
       console.log('receiving get request');
    });
    app.post('/somePostRequest', function(req, res, next) {
       console.log('receiving post request');
    });
    app.listen(80); //port 80 need to run as root

    console.log("app listening on %d ", 80);

var server = http.createServer(app);
    server.listen(port);

console.log("http server listening on %d", port);

var userId;
var wss = new WebSocketServer({server: server});
    wss.on("connection", function (ws) {

    console.info("websocket connection open");

    var timestamp = new Date().getTime();
    userId = timestamp;

    ws.send(JSON.stringify({msgType:"onOpenConnection", msg:{connectionId:timestamp}}));


    ws.on("message", function (data, flags) {
        console.log("websocket received a message");
        var clientMsg = data;

        ws.send(JSON.stringify({msg:{connectionId:userId}}));


    });

    ws.on("close", function () {
        console.log("websocket connection close");
    });
});
console.log("websocket server created");

I'm not sure if Windows' "shell" supports this, but on Linux:

print "\033[2J"

In my opinion calling cls with os is a bad idea generally. Imagine if I manage to change the cls or clear command on your system, and you run your script as admin or root.

Please check this answer

 window.onscroll = function(ev) {
    if ((window.innerHeight + window.scrollY) >= document.body.offsetHeight) {
       console.log("bottom");
    }
};

You can do footerHeight - document.body.offsetHeight to see if you are near the footer or reached the footer

By default, unlike an exception, a warning doesn't interrupt.

After import warnings, it is possible to specify a Warnings class when generating a warning. If one is not specified, it is literally UserWarning by default.

>>> warnings.warn('This is a default warning.')
<string>:1: UserWarning: This is a default warning.

To simply use a preexisting class instead, e.g. DeprecationWarning:

>>> warnings.warn('This is a particular warning.', DeprecationWarning)
<string>:1: DeprecationWarning: This is a particular warning.

Creating a custom warning class is similar to creating a custom exception class:

>>> class MyCustomWarning(UserWarning):
...     pass
... 
... warnings.warn('This is my custom warning.', MyCustomWarning)

<string>:1: MyCustomWarning: This is my custom warning.

For testing, consider assertWarns or assertWarnsRegex.

As an alternative, especially for standalone applications, consider the logging module. It can log messages having a level of debug, info, warning, error, etc. Log messages having a level of warning or higher are by default printed to stderr.

Java implicitly assumes a reference to the current object for methods called like this. So

// Test2.java
public class Test2 {
    public void testMethod() {
        testMethod2();
    }

    // ...
}

Is exactly the same as

// Test2.java
public class Test2 {
    public void testMethod() {
        this.testMethod2();
    }

    // ...
}

I prefer the second version to make more clear what you want to do.

An AsyncTask is used to do some background computation and publish the result to the UI thread (with optional progress updates). Since you're not concerned with UI, then a Handler or Thread seems more appropriate.

You can spawn a background Thread and pass messages back to your main thread by using the Handler's post method.

I would have thought this would have been answered already - but surely what you want is this: box-shadow: 0 0 3px #CC0000;

The script from Erwinus works great, but isn't very clearly coded. I took the liberty to clean it up and decipher what it was doing. I've made these changes:

• Meaningful variable names
• Use of prototype.
• require() uses an argument variable
• No alert() messages are returned by default
• Fixed some syntax errors and scope issues I was getting

Thanks again to Erwinus, the functionality itself is spot on.

I've seen several solutions but I wasn't convinced by any of them. Either very complicated or too simple (non-reusable).

This is my favourite approach at the moment:

mEditText.setOnTouchListener(
        new OnEditTextRightDrawableTouchListener(mEditText) {
          @Override
          public void OnDrawableClick() {
            // The right drawable was clicked. Your action goes here.
          }
        });

And this is the reusable touch listener:

import android.graphics.drawable.Drawable;
import android.support.annotation.NonNull;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.EditText;

public abstract class OnEditTextRightDrawableTouchListener implements OnTouchListener {

  private final EditText mEditText;

  public OnEditTextRightDrawableTouchListener(@NonNull final EditText editText) {
    mEditText = editText;
  }

  @Override
  public boolean onTouch(View view, MotionEvent motionEvent) {
    if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
      final int DRAWABLE_RIGHT_POSITION = 2;
      final Drawable drawable = mEditText.getCompoundDrawables()[DRAWABLE_RIGHT_POSITION];
      if (drawable != null) {
        final float touchEventX = motionEvent.getX();
        final int touchAreaRight = mEditText.getRight();
        final int touchAreaLeft = touchAreaRight - drawable.getBounds().width();
        if (touchEventX >= touchAreaLeft && touchEventX <= touchAreaRight) {
          view.performClick();
          OnDrawableClick();
        }
        return true;
      }
    }
    return false;
  }

  public abstract void OnDrawableClick();
}

You can look at the Gist here.

If you aim to have the "circle" maintain a visual aspect ratio of 1 no matter what the data coordinates are, you could use the scatter() method. http://matplotlib.org/1.3.1/api/pyplot_api.html#matplotlib.pyplot.scatter

import matplotlib.pyplot as plt
x = [1, 2, 3, 4, 5]
y = [10, 20, 30, 40, 50]
r = [100, 80, 60, 40, 20] # in points, not data units
fig, ax = plt.subplots(1, 1)
ax.scatter(x, y, s=r)
fig.show()

[Update Sept 2020] Although my original answer here, from many years ago, seems to be helpful and is still getting upvotes, I now use the GSON library from Google, which I find to be more intuitive.

I've got the following code:

public void testJackson() throws IOException {  
    ObjectMapper mapper = new ObjectMapper(); 
    File from = new File("albumnList.txt"); 
    TypeReference<HashMap<String,Object>> typeRef 
            = new TypeReference<HashMap<String,Object>>() {};

    HashMap<String,Object> o = mapper.readValue(from, typeRef); 
    System.out.println("Got " + o); 
}   

It's reading from a file, but mapper.readValue() will also accept an InputStream and you can obtain an InputStream from a string by using the following:

new ByteArrayInputStream(astring.getBytes("UTF-8")); 

There's a bit more explanation about the mapper on my blog.

Just a modified version of GregM's answer:

cd /D %folder%

echo Entire content of %cd% will be deleted. Press Ctrl-C to abort

The EASIEST way to get a very usable text file is to download S3 Browser http://s3browser.com/ and use the Web URLs Generator to produce a list of complete link paths. It is very handy and involves about 3 clicks.

Best of luck to you.

If you are unsure of the size of the array or if it can change you can do this to have a static array.

ArrayList<Player> thePlayersList = new ArrayList<Player>(); 

thePlayersList.add(new Player(1));
thePlayersList.add(new Player(2));
.
.
//Some code here that changes the number of players e.g

Players[] thePlayers = thePlayersList.toArray();

Use ng-click in place of onclick. and its as simple as that:

<a href="www.mysite.com" ng-click="return theFunction();">Item</a>

<script type="text/javascript">
function theFunction () {
    // return true or false, depending on whether you want to allow 
    // the`href` property to follow through or not
 }
</script>

You should first add a new route in global.asax:

routes.MapRoute(
                "MyNewRoute",
                "{controller}/{action}/{date}",
                new { controller="YourControllerName", action="YourActionName", date = "" }
            );

The on your Controller:

        public ActionResult MyActionName(DateTime date)
        {

        }

Remember to keep your default route at the bottom of the RegisterRoutes method. Be advised that the engine will try to cast whatever value you send in {date} as a DateTime example, so if it can't be casted then an exception will be thrown. If your date string contains spaces or : you could HTML.Encode them so the URL could be parsed correctly. If no, then you could have another DateTime representation.

You can use the Random generator to generate a random index and return the element at that index:

//initialization
Random generator = new Random();
int randomIndex = generator.nextInt(myArray.length);
return myArray[randomIndex];

For Java (not php, not javascript, not anyother):

txt.replaceAll("\\p{javaSpaceChar}{2,}"," ")

Jonathon gave you an approach using dict comprehensions in his answer. Here is an approach that deals with your do something part.

If you want to do something with the values of the dictionary, you don't need a dictionary comprehension at all:

I'm using iteritems() since you tagged your question with python-2.7

results = map(some_function, [(k,v) for k,v in a_dict.iteritems() if 'foo' in k])

Now the result will be in a list with some_function applied to each key/value pair of the dictionary, that has foo in its key.

If you just want to deal with the values and ignore the keys, just change the list comprehension:

results = map(some_function, [v for k,v in a_dict.iteritems() if 'foo' in k])

some_function can be any callable, so a lambda would work as well:

results = map(lambda x: x*2, [v for k,v in a_dict.iteritems() if 'foo' in k])

The inner list is actually not required, as you can pass a generator expression to map as well:

>>> map(lambda a: a[0]*a[1], ((k,v) for k,v in {2:2, 3:2}.iteritems() if k == 2))
[4]

Since you have an object, not a jQuery wrapper, you need to use a different variant of $.each()

$.each(json, function (key, data) {
    console.log(key)
    $.each(data, function (index, data) {
        console.log('index', data)
    })
})

Demo: Fiddle

Why does it take three branches/merges for every task? Can you explain more about that?

If you use a bug tracking system you can use the bug number as part of the branch name. This will keep the branch names unique, and you can prefix them with a short and descriptive word or two to keep them human readable, like "ResizeWindow-43523". It also helps make things easier when you go to clean up branches, since you can look up the associated bug. This is how I usually name my branches.

Since these branches are eventually getting merged back into master, you should be safe deleting them after you merge. Unless you're merging with --squash, the entire history of the branch will still exist should you ever need it.

Use a white space to match all descendants of an element:

div.dropdown * {
    color: red;
}

x y matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.

The asterisk * matches any element.

Official Specification: CSS 2.1: Chapter 5.5: Descendant Selectors

For some situations regexp might help. Here is an example I've checked on Oracle, and it works.

select * from my_table where REGEXP_LIKE (search_column, 'value1|value2')

But there is a number of drawbacks with it:

1. Any column it applied should be converted to varchar/char, at least implicitly.
2. Need to be careful with special characters.
3. It can slow down performance - in my case IN version uses index and range scan, and REGEXP version do full scan.

If you don't already have a C/C++ development environment installed that is compatible with the Visual Studio binaries distributed by Python.org, then you should stick to installing only pure Python packages or packages for which a Windows binary is available.

Fortunately, there are PyCrypto binaries available for Windows: http://www.voidspace.org.uk/python/modules.shtml#pycrypto

UPDATE:
As @Udi suggests in the comment below, the following command also installs pycrypto and can be used in virtualenv as well:

easy_install http://www.voidspace.org.uk/python/pycrypto-2.6.1/pycrypto-2.6.1.win32-py2.7.exe

ngModel is responsible for:

• Binding the view into the model, which other directives such as input, textarea or select require.
• Providing validation behavior (i.e. required, number, email, url).
• Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
• Setting related css classes on the element (ng-valid, ng-invalid, ng-dirty, ng-pristine, ng-touched, ng-untouched) including animations.
• Registering the control with its parent form.

ngBind

This directive executes at priority level 0.

ngBind is responsible for:

• Replacing the text content of the specified HTML element with the value of a given expression.

The REST doesn't prevent body inclusion with DELETE request but it is better to use query string as it is most standarized (unless you need the data to be encrypted)

I got it to work with angular 2 by doing following:

let options:any = {}
option.header = new Headers({
    'header_name':'value'
});

options.search = new URLSearchParams();
options.search.set("query_string_key", "query_string_value");

this.http.delete("/your/url", options).subscribe(...)

try

$("#from").datepicker().datepicker('disable');

I will try to give the solution that worked for me. It seems that different set of problems can lead to this situation.

32 bit software works in 64 bit OS. I installed anaconda-3 (32 bit) in my 64 bit OS. It was working perfectly fine. I decided to install tensorflow in my machine and it wouldn't install at first. I was using conda environment to install tensorflow and got this error.

Solution is if you are running 64 bit OS, install 64 bit anaconda and if 32 bit OS then 32 bit anaconda. Then follow the standard procedure mentioned in tensorflow website for windows (anaconda installation). This made it possible to install tensorflow without any problem.

=> [4, 5, 6]                                                            
>> x.shift 
=> 4
>> x                                                                    
=> [5, 6] 

If you want to remove n starting elements you can use x.shift(n)

jQuery keeps a reference to the vanilla JS form element, and this contains a reference to all of the form's child elements. You could simply grab the reference and proceed forward:

var someForm = $('#SomeForm');

$.each(someForm[0].elements, function(index, elem){
    //Do something here.
});

C++ solution found here (http://www.cplusplus.com/forum/unices/16430/)

#include <signal.h>
#include <stdio.h>
#include <unistd.h>
void ouch(int sig)
{
    printf("OUCH! - I got signal %d\n", sig);
}
int main()
{
    struct sigaction act;
    act.sa_handler = ouch;
    sigemptyset(&act.sa_mask);
    act.sa_flags = 0;
    sigaction(SIGINT, &act, 0);
    while(1) {
        printf("Hello World!\n");
        sleep(1);
    }
}

I think of %w() as a "word array" - the elements are delimited by spaces and it returns an array of strings.

There are other % literals:

• %r() is another way to write a regular expression.
• %q() is another way to write a single-quoted string (and can be multi-line, which is useful)
• %Q() gives a double-quoted string
• %x() is a shell command
• %i() gives an array of symbols (Ruby >= 2.0.0)
• %s() turns foo into a symbol (:foo)

I don't know any others, but there may be some lurking around in there...

First create an xpath selector function.

function _x(STR_XPATH) {
    var xresult = document.evaluate(STR_XPATH, document, null, XPathResult.ANY_TYPE, null);
    var xnodes = [];
    var xres;
    while (xres = xresult.iterateNext()) {
        xnodes.push(xres);
    }

    return xnodes;
}

To use the xpath selector with jquery, you can do like this:

$(_x('/html/.//div[@id="text"]')).attr('id', 'modified-text');

Hope this can help.

Currently evaluation in the console is performed in the context of the main frame in the page and it adheres to the same cross-origin policy as the main frame itself. This means that you cannot access elements in the iframe unless the main frame can. You can still set breakpoints in and debug your code using Scripts panel though.

Update: This is no longer true. See Metagrapher's answer.

This is so called file local variables, that are understood by Emacs and set correspondingly. See corresponding section in Emacs manual - you can define them either in header or in footer of file

You tend to handle number of arguments with this sort of logic:

IF "%1"=="" GOTO HAVE_0
IF "%2"=="" GOTO HAVE_1
IF "%3"=="" GOTO HAVE_2

etc.

If you have more than 9 arguments then you are screwed with this approach though. There are various hacks for creating counters which you can find here, but be warned these are not for the faint hearted.

You need to use the CONCAT() function in MySQL for string concatenation:

UPDATE categories SET code = CONCAT(code, '_standard') WHERE id = 1;

You'll get that error once your numbers are greater than sys.maxsize:

>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

You can confirm this by checking:

>>> import sys
>>> sys.maxsize
2147483647

To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:

>>> preds = np.zeros((1, 3))

Add the following:

using System.Linq

...and call ToList() on the IQueryable<>.

Calling .parents(".box .something1") will return all parent elements that match the selector .box .something. In other words, it will return parent elements that are .something1 and are inside of .box.

You need to get the children of the closest parent, like this:

$(this).closest('.box').children('.something1')

This code calls .closest to get the innermost parent matching a selector, then calls .children on that parent element to find the uncle you're looking for.

Update: https://stackoverflow.com/a/53714583/302079 improves this by adding exit status and a cleanup function.

trap "exit" INT TERM
trap "kill 0" EXIT

Why convert INT and TERM to exit? Because both should trigger the kill 0 without entering an infinite loop.

Why trigger kill 0 on EXIT? Because normal script exits should trigger kill 0, too.

Why kill 0? Because nested subshells need to be killed as well. This will take down the whole process tree.

You can use .change for what you want

$("input[@name='lom']").change(function(){
    // Do something interesting here
});

as of jQuery 1.3

you no longer need the '@'. Correct way to select is:

$("input[name='lom']")

Seems the SMTP as internet standard uses only reliable Transport protocol. RFC821 has TCP, NCP, NITS as examples!

Even when the number is rounded when the page is painted, the full value is preserved in memory and used for subsequent child calculation. For example, if your box of 100.4999px paints to 100px, it's child with a width of 50% will be calculated as .5*100.4999 instead of .5*100. And so on to deeper levels.

I've created deeply nested grid layout systems where parents widths are ems, and children are percents, and including up to four decimal points upstream had a noticeable impact.

Edge case, sure, but something to keep in mind.

https://socket.io/docs/#What-Socket-IO-is-not (with my emphasis)

What Socket.IO is not

Socket.IO is NOT a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the packet id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server either. Please see the protocol specification here.

// WARNING: the client will NOT be able to connect!
const client = io('ws://echo.websocket.org');

Instead of doing file_put_contents(***WebSiteURL***...) you need to use the server path to /cache/lang/file.php (e.g. /home/content/site/folders/filename.php).

You cannot open a file over HTTP and expect it to be written. Instead you need to open it using the local path.

You can use list.sort with its optional key parameter and a lambda expression:

>>> lst = [
...     ['John',2],
...     ['Jim',9],
...     ['Jason',1]
... ]
>>> lst.sort(key=lambda x:x[1])
>>> lst
[['Jason', 1], ['John', 2], ['Jim', 9]]
>>>

This will sort the list in-place.

Note that for large lists, it will be faster to use operator.itemgetter instead of a lambda:

>>> from operator import itemgetter
>>> lst = [
...     ['John',2],
...     ['Jim',9],
...     ['Jason',1]
... ]
>>> lst.sort(key=itemgetter(1))
>>> lst
[['Jason', 1], ['John', 2], ['Jim', 9]]
>>>

Maybe just another thing about LEA instruction. You can also use LEA for fast multiplying registers by 3, 5 or 9.

LEA EAX, [EAX * 2 + EAX]   ;EAX = EAX * 3
LEA EAX, [EAX * 4 + EAX]   ;EAX = EAX * 5
LEA EAX, [EAX * 8 + EAX]   ;EAX = EAX * 9

I had the same problem, and in my case, all I had to do was the good ol'

read the error message...

My error message said:

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema. - configuration.entry should be one of these: function | object { : non-empty string | [non-empty string] } | non-empty string | [non-empty string] -> The entry point(s) of the compilation. Details: * configuration.entry should be an instance of function -> A Function returning an entry object, an entry string, an entry array or a promise to these things. * configuration.entry['styles'] should be a string. -> The string is resolved to a module which is loaded upon startup. * configuration.entry['styles'] should not contain the item 'C:\MojiFajlovi\Faks\11Master\1Semestar\UDD-UpravljanjeDigitalnimDokumentima\Projekat\ nc-front\node_modules\bootstrap\dist\css\bootstrap.min.css' twice.

As the bold-ed error message line said, I just opened angular.json file and found the styles to look like this:

"styles": [
      "./node_modules/bootstrap/dist/css/bootstrap.min.css",
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css" <-- **marked line**
    ],

... so I just removed the marked line...

and it all went well. :)

You can build your HttpContent using the combination of JObject to avoid and JProperty and then call ToString() on it when building the StringContent:

        /*{
          "agent": {                             
            "name": "Agent Name",                
            "version": 1                                                          
          },
          "username": "Username",                                   
          "password": "User Password",
          "token": "xxxxxx"
        }*/

        JObject payLoad = new JObject(
            new JProperty("agent", 
                new JObject(
                    new JProperty("name", "Agent Name"),
                    new JProperty("version", 1)
                    ),
                new JProperty("username", "Username"),
                new JProperty("password", "User Password"),
                new JProperty("token", "xxxxxx")    
                )
            );

        using (HttpClient client = new HttpClient())
        {
            var httpContent = new StringContent(payLoad.ToString(), Encoding.UTF8, "application/json");

            using (HttpResponseMessage response = await client.PostAsync(requestUri, httpContent))
            {
                response.EnsureSuccessStatusCode();
                string responseBody = await response.Content.ReadAsStringAsync();
                return JObject.Parse(responseBody);
            }
        }

if the zipcode field is not a required field then add null=True and blank=True, then run makemigrations and migrate command to successfully reflect the changes in the database.

You can use:

<script type="text/javascript">
    function prepareFrame() {
        var ifrm = document.createElement("iframe");
        ifrm.setAttribute("src", "http://google.com/");
        ifrm.style.width = "640px";
        ifrm.style.height = "480px";
        document.body.appendChild(ifrm);
    }
</script> 

also check basics of the iFrame element

if (yourObject instanceof yourClassName) will evaluate to false if yourObject is null.

I had to face this problem, too. Unfortunately, none of the answers (here and in dozens of other pages) has been satisfactory to me, as I still cannot reach dates beyond the year 2038 due to 32 bit integer casts somewhere.

A solution that did work for me in the end was to use float variables, so I could have at least a max date of 2262-04-11T23:47:16.854775849. Still, this doesn't cover the entire datetime domain, but it is sufficient for my needs and may help others encountering the same problem.

-- date variables
declare @ts bigint; -- 64 bit time stamp, 100ns precision
declare @d datetime2(7) = GETUTCDATE(); -- 'now'
-- select @d = '2262-04-11T23:47:16.854775849'; -- this would be the max date

-- constants:
declare @epoch datetime2(7) = cast('1970-01-01T00:00:00' as datetime2(7));
declare @epochdiff int = 25567; -- = days between 1900-01-01 and 1970-01-01
declare @ticksofday bigint = 864000000000; -- = (24*60*60*1000*1000*10)

-- helper variables:
declare @datepart float;
declare @timepart float;
declare @restored datetime2(7);

-- algorithm:
select @ts = DATEDIFF_BIG(NANOSECOND, @epoch, @d) / 100; -- 'now' in ticks according to unix epoch
select @timepart = (@ts % @ticksofday) / @ticksofday; -- extract time part and scale it to fractional part (i. e. 1 hour is 1/24th of a day)
select @datepart = (@ts - @timepart) / @ticksofday; -- extract date part and scale it to fractional part
select @restored = cast(@epochdiff + @datepart + @timepart as datetime); -- rebuild parts to a datetime value

-- query original datetime, intermediate timestamp and restored datetime for comparison
select
  @d original,
  @ts unix64,
  @restored restored
;

-- example result for max date:
-- +-----------------------------+-------------------+-----------------------------+
-- | original                    | unix64            | restored                    |
-- +-----------------------------+-------------------+-----------------------------+
-- | 2262-04-11 23:47:16.8547758 | 92233720368547758 | 2262-04-11 23:47:16.8533333 |
-- +-----------------------------+-------------------+-----------------------------+

There are some points to consider:

• 100ns precision is the requirement in my case, however this seems to be the standard resolution for 64 bit unix timestamps. If you use any other resolution, you have to adjust @ticksofday and the first line of the algorithm accordingly.
• I'm using other systems that have their problems with time zones etc. and I found the best solution for me would be always using UTC. For your needs, this may differ.
• 1900-01-01 is the origin date for datetime2, just as is the epoch 1970-01-01 for unix timestamps.
• floats helped me to solve the year-2038-problem and integer overflows and such, but keep in mind that floating point numbers are not very performant and may slow down processing of a big amount of timestamps. Also, floats may lead to loss of precision due to roundoff errors, as you can see in the comparison of the example results for the max date above (here, the error is about 1.4425ms).
• In the last line of the algorithm there is a cast to datetime. Unfortunately, there is no explicit cast from numeric values to datetime2 allowed, but it is allowed to cast numerics to datetime explicitly and this, in turn, is cast implicitly to datetime2. This may be correct, for now, but may change in future versions of SQL Server: Either there will be a dateadd_big() function or the explicit cast to datetime2 will be allowed or the explicit cast to datetime will be disallowed, so this may either break or there may come an easier way some day.

Using plain old JavaScript worked for me:
document.querySelector('#elementName').click();

 sizeof(buffer) == sizeof(char*) 

Use length instead.

Also, better to use fopen with "wb"....

Worked a day for this project. It maybe useful for u. I compressed and combined both Network and GPS. Plug and play directly in MainActivity.java (There are some DIY function for display result)

To show how much fun it is to create some functions that are fail fast I've written the following 3 functions.

One creates an AES key, one encodes it and one decodes it back. These three methods can be used with Java 8 (without dependence of internal classes or outside dependencies):

public static SecretKey generateAESKey(int keysize)
        throws InvalidParameterException {
    try {
        if (Cipher.getMaxAllowedKeyLength("AES") < keysize) {
            // this may be an issue if unlimited crypto is not installed
            throw new InvalidParameterException("Key size of " + keysize
                    + " not supported in this runtime");
        }

        final KeyGenerator keyGen = KeyGenerator.getInstance("AES");
        keyGen.init(keysize);
        return keyGen.generateKey();
    } catch (final NoSuchAlgorithmException e) {
        // AES functionality is a requirement for any Java SE runtime
        throw new IllegalStateException(
                "AES should always be present in a Java SE runtime", e);
    }
}

public static SecretKey decodeBase64ToAESKey(final String encodedKey)
        throws IllegalArgumentException {
    try {
        // throws IllegalArgumentException - if src is not in valid Base64
        // scheme
        final byte[] keyData = Base64.getDecoder().decode(encodedKey);
        final int keysize = keyData.length * Byte.SIZE;

        // this should be checked by a SecretKeyFactory, but that doesn't exist for AES
        switch (keysize) {
        case 128:
        case 192:
        case 256:
            break;
        default:
            throw new IllegalArgumentException("Invalid key size for AES: " + keysize);
        }

        if (Cipher.getMaxAllowedKeyLength("AES") < keysize) {
            // this may be an issue if unlimited crypto is not installed
            throw new IllegalArgumentException("Key size of " + keysize
                    + " not supported in this runtime");
        }

        // throws IllegalArgumentException - if key is empty
        final SecretKeySpec aesKey = new SecretKeySpec(keyData, "AES");
        return aesKey;
    } catch (final NoSuchAlgorithmException e) {
        // AES functionality is a requirement for any Java SE runtime
        throw new IllegalStateException(
                "AES should always be present in a Java SE runtime", e);
    }
}

public static String encodeAESKeyToBase64(final SecretKey aesKey)
        throws IllegalArgumentException {
    if (!aesKey.getAlgorithm().equalsIgnoreCase("AES")) {
        throw new IllegalArgumentException("Not an AES key");
    }

    final byte[] keyData = aesKey.getEncoded();
    final String encodedKey = Base64.getEncoder().encodeToString(keyData);
    return encodedKey;
}

The real answer is: you can't reverse it in place, but you can create a new string that is the reverse.

Just as an exercise to play with recursion: sometimes when you go to an interview, the interviewer may ask you how to do this using recursion, and I think the "preferred answer" might be "I would rather not do this in recursion as it can easily cause a stack overflow" (because it is O(n) rather than O(log n). If it is O(log n), it is quite difficult to get a stack overflow -- 4 billion items could be handled by a stack level of 32, as 2 ** 32 is 4294967296. But if it is O(n), then it can easily get a stack overflow.

Sometimes the interviewer will still ask you, "just as an exercise, why don't you still write it using recursion?" And here it is:

String.prototype.reverse = function() {

To try getting a stack overflow, I changed 1000 to 10000 in Google Chrome, and it reported:

RangeError: Maximum call stack size exceeded

Yes, you can!

Or if not those terms exactly, then at least the next best thing. In 2020 this is now very straightforward using the CSS math functions: min(), max(), and clamp().

A min calculation picks the smallest from a comma separated list of values (of any length). This can be used to define a max-padding or max-margin rule:

padding-right: min(50px, 5%);

A max calculation similarly picks the largest from a comma separated list of values (of any length). This can be used to define a min-padding or min-margin rule:

padding-right: max(15px, 5%);

A clamp takes three values; the minimum, preferred, and maximum values, in that order.

padding-right: clamp(15px, 5%, 50px);

MDN specifies that clamp is actually just shorthand for:

max(MINIMUM, min(PREFERRED, MAXIMUM))

Here is a clamp being used to contain a 25vw margin between the values 100px and 200px:

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

.container {
  width: 100vw;
  border: 2px dashed red;
}

.margin {
  width: auto;
  min-width: min-content;
  background-color: lightblue;
  padding: 10px;
  margin-right: clamp(100px, 25vw, 200px);
}

<div class="container">
  <div class="margin">
    The margin-right on this div uses 25vw as its preferred value,
    100px as its minimum, and 200px as its maximum.
  </div>
</div>

The math functions can be used in all sorts of different scenarios, even potentially obscure ones like scaling font-size - they are not just for controlling margin and padding. Check out the full list of use cases at the MDN links at the top of this post.

Here is the caniuse list of browser support. Coverage is generally very good, including almost all modern browsers - with the exception, it appears, of some secondary mobile browsers although have not tested this myself.

I have found this useful more than once when the DataGrid is bound to a table.

        DataTable dt = (DataTable)dgvData.DataSource;
        DataRow row = dt.NewRow();
        foreach (var something in something)
        {
           row["ColumnName"] = something ;               
        }
        dt.Rows.Add(row);
        dgvData.DataSource = dt;

To whomever it may help,

I had that nasty crash if estimatedItemSize was set. Even if I returned 0 in numberOfItemsInSection. Therefore, the cells themselves and their auto-layout were not the cause of the crash... The collectionView just crashed, even when empty, just because estimatedItemSize was set for self-sizing.

In my case I reorganized my project, from a controller containing a collectionView to a collectionViewController, and it worked.

Go figure.

let VC1 = self.storyboard!.instantiateViewController(withIdentifier: "MyCustomViewController") as! ViewController
let navController = UINavigationController(rootViewController: VC1)
self.present(navController, animated:true, completion: nil)

"each" uses callback function. Callback function execute irrespective of the calling function,so it is not possible to return to calling function from callback function.

use for loop if you have to stop the loop execution based on some condition and remain in to the same function.

JS:

var verifyPaymentType = function () {
  var checkboxes = $('.wish_payment_type .checkbox');
  var inputs = checkboxes.find('input');
  var first = inputs.first()[0];

  inputs.on('change', function () {
    this.setCustomValidity('');
  });

  first.setCustomValidity(checkboxes.find('input:checked').length === 0 ? 'Choose one' : '');
}

$('#submit').click(verifyPaymentType);

You can simply write

Worksheets.Copy

in lieu of running a cycle. By default the worksheet collection is reproduced in a new workbook.

It is proven to function in 2010 version of XL.

zvolkov's answer is the perfect one to find out if there is such a customer. If you need to use the customer afterwards, you can do:

Customer customer = list.FirstOrDefault(cus => cus.FirstName == "John");
if (customer != null)
{
    // Use customer
}

I know this isn't what you were asking, but I thought I'd pre-empt a follow-on question :) (Of course, this only finds the first such customer... to find all of them, just use a normal where clause.)

Another option if you are looking for 3.4.2 or 3.5.1 is this archive on GitHub.

Python3-Android 3.4.2 or Python3-Android 3.5.1

It currently supports Python 3.4.2 or 3.5.1 and the 10d version of the NDK. It can also support 3.3 and 9c, 11c and 12

It's nice in that you simply download it, run make and you get the .so or the .a

I currently use this to run raw Python on android devices. With a couple modifications to the build files you can also make x86 and armeabi 64 bit

Realise this is an old thread, but after seeing lots of scripts like this I noticed that you can do this just using conditional formatting.

Assuming the "Status" was Column D:

Highlight cells > right click > conditional formatting. Select "Custom Formula Is" and set the formula as

=RegExMatch($D2,"Complete")

or

=OR(RegExMatch($D2,"Complete"),RegExMatch($D2,"complete"))

Edit (thanks to Frederik Schøning)

=RegExMatch($D2,"(?i)Complete") then set the range to cover all the rows e.g. A2:Z10. This is case insensitive, so will match complete, Complete or CoMpLeTe.

You could then add other rules for "Not Started" etc. The $ is very important. It denotes an absolute reference. Without it cell A2 would look at D2, but B2 would look at E2, so you'd get inconsistent formatting on any given row.

Italian version:

=CONCATENA(
    DECIMALE.HEX(CASUALE.TRA(0;4294967295);8);"-";
    DECIMALE.HEX(CASUALE.TRA(0;42949);4);"-";
    DECIMALE.HEX(CASUALE.TRA(0;42949);4);"-";
    DECIMALE.HEX(CASUALE.TRA(0;42949);4);"-";
    DECIMALE.HEX(CASUALE.TRA(0;4294967295);8);
    DECIMALE.HEX(CASUALE.TRA(0;42949);4))

This should do the trick:

pw_bytes.decode("utf-8")

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark` 
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          FIRST";

http://dev.mysql.com/doc/refman/5.1/en/alter-table.html

I've just had the same problem.

You only get the text twice in your result if you include a match group (in brackets) and the 'g' (global) modifier. The first item always is the first result, normally OK when using match(reg) on a short string, however when using a construct like:

while ((result = reg.exec(string)) !== null){
    console.log(result);
}

the results are a little different.

Try the following code:

var regEx = new RegExp('([0-9]+ (cat|fish))','g'), sampleString="1 cat and 2 fish";
var result = sample_string.match(regEx);
console.log(JSON.stringify(result));
// ["1 cat","2 fish"]

var reg = new RegExp('[0-9]+ (cat|fish)','g'), sampleString="1 cat and 2 fish";
while ((result = reg.exec(sampleString)) !== null) {
    console.dir(JSON.stringify(result))
};
// '["1 cat","cat"]'
// '["2 fish","fish"]'

var reg = new RegExp('([0-9]+ (cat|fish))','g'), sampleString="1 cat and 2 fish";
while ((result = reg.exec(sampleString)) !== null){
    console.dir(JSON.stringify(result))
};
// '["1 cat","1 cat","cat"]'
// '["2 fish","2 fish","fish"]'

(tested on recent V8 - Chrome, Node.js)

The best answer is currently a comment which I can't upvote, so credit to @Mic.

I'm surprised no-one has posted this "neat trick" version which doesn't use any JavaScript, it only uses CSS.

#radio1 {
    display: none;
}

#wrapper {
    /* NOTE: This wrapper div is not needed provided you can position the label for #radio1 on top of #radio2 using some other technique. */
    position: relative;
}

#radio1:not(:checked) ~ * label[for="radio1"] {
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
}
#radio1:checked ~ * label[for="radio1"] {
    display: none;
}

/* Non-essential styles: */ 

label[for],
label:not([for="radio1"]) {
    cursor: pointer;
    border-radius: 7px;
}
label[for]:hover + label,
label:not([for="radio1"]):hover {
    background-color: #ccc;
}

<input type="radio" name="group1" id="radio1" checked="checked"  />

<p>Look mum, <strong>no JavaScript!</strong></p>

<div id="wrapper">
    <label for="radio1"></label>
    <label>
        <input type="radio" name="group1" id="radio2" />
        You can toggle me on and off!
    </label>
</div>

Explanation:

• #radio1 (<input type="radio" id="radio2" />) is always hidden.
• Using CSS's :checked and :not(:checked) pseudo-class selectors with sibling selectors (+ and ~) allow other elements' style to be affected depending on whether or not an <input type="checkbox" /> or <input type="radio" /> is checked.
  • So when #radio1 is un-checked (or when #radio2 is checked) that causes a <label> to be overlayed on-top of #radio2 and that label has for="radio1", so clicking it will cause #radio1 to be checked, not #radio2.
  • IMPORTANT CAVEAT: CSS's sibling selector rules only allows selectors to select elements based on their ancestors and their ancestors earlier siblings. So you cannot style an element based on any other descendants of its ancestors.
    • This limitation will be removed when CSS4's :has() selector function is supported but as of November 2020 only PrinceXML supports :has() and it's currently looking like :has() will be dropped from CSS4 entirely owing to the difficulty of implementation.

This approach can be scaled to support multiple radio buttons:

#uncheckAll {
    display: none;
}

#uncheckAll:checked ~ * label[for="uncheckAll"] {
    display: none;
}

label {
    cursor: pointer;
}

label:not([for]) {
    position: relative;
}

label[for="uncheckAll"] {
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
}

input[name="group1"]:not(:checked) + label[for="uncheckAll"] {
    display: none;
}

<input type="radio" name="group1" id="uncheckAll" checked="checked"  />

<label>
    <input type="radio" name="group1" id="radio2" />
    <label for="uncheckAll"></label>
    You can toggle me on and off!
</label>

<label>
    <input type="radio" name="group1" id="radio3" />
    <label for="uncheckAll"></label>
    And me!
</label>

<label>
    <input type="radio" name="group1" id="aragorn" />
    <label for="uncheckAll"></label>
    And my sword!
</label>

<label>
    <input type="radio" name="group1" id="gimli" />
    <label for="uncheckAll"></label>
    And my axe!
</label>

PowerShell v5.0 adds Compress-Archive and Expand-Archive cmdlets. The linked pages have full examples, but the gist of it is:

# Create a zip file with the contents of C:\Stuff\
Compress-Archive -Path C:\Stuff -DestinationPath archive.zip

# Add more files to the zip file
# (Existing files in the zip file with the same name are replaced)
Compress-Archive -Path C:\OtherStuff\*.txt -Update -DestinationPath archive.zip

# Extract the zip file to C:\Destination\
Expand-Archive -Path archive.zip -DestinationPath C:\Destination

In your template, you have access to all the variables that are members of the current $scope. So, tobedone should be $scope.tobedone, and then you can display it with {{tobedone}}, or [[tobedone]] in your case.

The browser will not fire the onchange event for <div> elements.

I think the reasoning behind this is that these elements won't change unless modified by javascript. If you are already having to modify the element yourself (rather than the user doing it), then you can just call the appropriate accompanying code at the same time that you modify the element, like so:

 $("#content").html('something').each(function() { });

You could also manually fire an event like this:

 $("#content").html('something').change();

If neither of these solutions work for your situation, could you please give more information on what you are specifically trying to accomplish?

The only way in MySQL to do this dynamically is with Prepared statements. Here is a good article about them:

Dynamic pivot tables (transform rows to columns)

Your code would look like this:

SET @sql = NULL;
SELECT
  GROUP_CONCAT(DISTINCT
    CONCAT(
      'MAX(IF(pa.fieldname = ''',
      fieldname,
      ''', pa.fieldvalue, NULL)) AS ',
      fieldname
    )
  ) INTO @sql
FROM product_additional;

SET @sql = CONCAT('SELECT p.id
                    , p.name
                    , p.description, ', @sql, ' 
                   FROM product p
                   LEFT JOIN product_additional AS pa 
                    ON p.id = pa.id
                   GROUP BY p.id');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

In many cases, when we are inside a string we are enclosed by a double quote, or while writing a statement we don't want to press escape and go to end of that line with arrow key and press the semicolon(;) just to end the line. Write the following line inside your vimrc file:

imap <C-l> <Esc>$a

What does the line say? It maps Ctrl+l to a series of commands. It is equivalent to you pressing Esc (command mode), $ (end of line), a (append) at once.

Hope you realise, java.util.Enumeration is different from the Java 1.5 Enum types.

You can simply use YourEnum.valueOf("String") to get the equivalent enum type.

Thus if your enum is defined as so:

public enum Day {
    SUNDAY, MONDAY, TUESDAY, WEDNESDAY, 
    THURSDAY, FRIDAY, SATURDAY
}

You could do this:

String day = "SUNDAY";

Day dayEnum = Day.valueOf(day);

I got same problem if i understand your question correctly, I want to know the last inserted id after every insert performance in SQLite operation. i tried the following statement:

select * from table_name order by id desc limit 1

The id is the first column and primary key of the table_name, the mentioned statement show me the record with the largest id.

But the premise is u never deleted any row so the numbers of id equal to the numbers of rows.

Go to

Settings -> Android SDK -> SDK Tools ->

and make sure you install Google Play Services

The basic difference is that getOne is lazy loaded and findOne is not.

Consider the following example:

public static String NON_EXISTING_ID = -1;
...
MyEntity getEnt = myEntityRepository.getOne(NON_EXISTING_ID);
MyEntity findEnt = myEntityRepository.findOne(NON_EXISTING_ID);

if(findEnt != null) {
     findEnt.getText(); // findEnt is null - this code is not executed
}

if(getEnt != null) {
     getEnt.getText(); // Throws exception - no data found, BUT getEnt is not null!!!
}

First download this JavaScript code, JSON2.js, that will help us serialize the object into a string.

In my example I'm posting the rows of a jqGrid via Ajax:

    var commissions = new Array();
    // Do several row data and do some push. In this example is just one push.
    var rowData = $(GRID_AGENTS).getRowData(ids[i]);
    commissions.push(rowData);
    $.ajax({
        type: "POST",
        traditional: true,
        url: '<%= Url.Content("~/") %>' + AREA + CONTROLLER + 'SubmitCommissions',
        async: true,
        data: JSON.stringify(commissions),
        dataType: "json",
        contentType: 'application/json; charset=utf-8',
        success: function (data) {
            if (data.Result) {
                jQuery(GRID_AGENTS).trigger('reloadGrid');
            }
            else {
                jAlert("A problem ocurred during updating", "Commissions Report");
            }
        }
    });

Now on the controller:

    [HttpPost]
    [JsonFilter(Param = "commissions", JsonDataType = typeof(List<CommissionsJs>))]
    public ActionResult SubmitCommissions(List<CommissionsJs> commissions)
    {
        var result = dosomething(commissions);
        var jsonData = new
        {
            Result = true,
            Message = "Success"
        };
        if (result < 1)
        {
            jsonData = new
            {
                Result = false,
                Message = "Problem"
            };
        }
        return Json(jsonData);
    }

Create a JsonFilter Class (thanks to JSC reference).

    public class JsonFilter : ActionFilterAttribute
    {
        public string Param { get; set; }
        public Type JsonDataType { get; set; }
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (filterContext.HttpContext.Request.ContentType.Contains("application/json"))
            {
                string inputContent;
                using (var sr = new StreamReader(filterContext.HttpContext.Request.InputStream))
                {
                    inputContent = sr.ReadToEnd();
                }
                var result = JsonConvert.DeserializeObject(inputContent, JsonDataType);
                filterContext.ActionParameters[Param] = result;
            }
        }
    }

Create another class so the filter can parse the JSON string to the actual manipulable object: This class comissionsJS are all the rows of my jqGrid.

    public class CommissionsJs
    {
        public string Amount { get; set; }

        public string CheckNumber { get; set; }

        public string Contract { get; set; }
        public string DatePayed { get; set; }
        public string DealerName { get; set; }
        public string ID { get; set; }
        public string IdAgentPayment { get; set; }
        public string Notes { get; set; }
        public string PaymentMethodName { get; set; }
        public string RowNumber { get; set; }
        public string AgentId { get; set; }
    }

I hope this example helps to illustrate how to post a complex object.

private AudioManager audio;

Inside onCreate:

audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);

Override onKeyDown:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    switch (keyCode) {
    case KeyEvent.KEYCODE_VOLUME_UP:
        audio.adjustStreamVolume(AudioManager.STREAM_MUSIC,
                AudioManager.ADJUST_RAISE, AudioManager.FLAG_SHOW_UI);
        return true;
    case KeyEvent.KEYCODE_VOLUME_DOWN:
        audio.adjustStreamVolume(AudioManager.STREAM_MUSIC,
                AudioManager.ADJUST_LOWER, AudioManager.FLAG_SHOW_UI);
        return true;
    default:
        return false;
    }
}

Sometimes it might depend on whether you are using code to access the database or not. If you are using "DriverJet" in your code instead of "DriverACE" (or an older version of the DAO library) such a problem is highly probable to happen. You just need to replace "DriverJet" with "DriverACE" and test.

All the metadata about the columns in Oracle Database is accessible using one of the following views.

user_tab_cols; -- For all tables owned by the user

all_tab_cols ; -- For all tables accessible to the user

dba_tab_cols; -- For all tables in the Database.

So, if you are looking for a column like ADD_TMS in SCOTT.EMP Table and add the column only if it does not exist, the PL/SQL Code would be along these lines..

DECLARE
  v_column_exists number := 0;  
BEGIN
  Select count(*) into v_column_exists
    from user_tab_cols
    where upper(column_name) = 'ADD_TMS'
      and upper(table_name) = 'EMP';
      --and owner = 'SCOTT --*might be required if you are using all/dba views

  if (v_column_exists = 0) then
      execute immediate 'alter table emp add (ADD_TMS date)';
  end if;
end;
/

If you are planning to run this as a script (not part of a procedure), the easiest way would be to include the alter command in the script and see the errors at the end of the script, assuming you have no Begin-End for the script..

If you have file1.sql

alter table t1 add col1 date;
alter table t1 add col2 date;
alter table t1 add col3 date;

And col2 is present,when the script is run, the other two columns would be added to the table and the log would show the error saying "col2" already exists, so you should be ok.

Take a look at ContextSingletonBeanFactoryLocator. It provides static accessors to get hold of Spring's contexts, assuming they have been registered in certain ways.

It's not pretty, and more complex than perhaps you'd like, but it works.

Just use the "JSON_UNESCAPED_SLASHES" Option (added after version 5.4).

json_encode($array,JSON_UNESCAPED_SLASHES);

To expand on what Peter said: Since you are looking to go from interface{} to string, type assertion will lead to headaches since you need to account for multiple incoming types. You'll have to assert each type possible and verify it is that type before using it.

Using fmt.Sprintf (https://golang.org/pkg/fmt/#Sprintf) automatically handles the interface conversion. Since you know your desired output type is always a string, Sprintf will handle whatever type is behind the interface without a bunch of extra code on your behalf.

I know this is an old question but for people searching, there is a PECL extension written in C that gives PHP multi-threading capability now, it's located here https://github.com/krakjoe/pthreads

Yes, the higher the z-index, the better. It will position your content element on top of every other element on the page. Say you have z-index to some elements on your page. Look for the highest and then give a higher z-index to your popup element. This way it will flow even over the other elements with z-index. If you don't have a z-index in any element on your page, you should give like z-index:2; or something higher.

Only one route enough for this

config.Routes.MapHttpRoute("DefaultApiWithAction", "{controller}/{action}");

And need to specify attribute HttpGet or HttpPost in all actions.

    return new string[] { "value1", "value2" };
}

[HttpGet]

You can try the Class Based View called RedirectView

from django.views.generic.base import RedirectView

urlpatterns = patterns('',
    url(r'^$', 'macmonster.views.home'),
    #url(r'^macmon_home$', 'macmonster.views.home'),
    url(r'^macmon_output/$', 'macmonster.views.output'),
    url(r'^macmon_about/$', 'macmonster.views.about'),
    url(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
)

Notice how as url in the <url_to_home_view> you need to actually specify the url.

permanent=False will return HTTP 302, while permanent=True will return HTTP 301.

Alternatively you can use django.shortcuts.redirect

Update for Django 2+ versions

With Django 2+, url() is deprecated and replaced by re_path(). Usage is exactly the same as url() with regular expressions. For replacements without the need of regular expression, use path().

from django.urls import re_path

re_path(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')

Just set the SelectedPath property before calling ShowDialog.

fdbLocation.SelectedPath = myFolder;

I landed on the same exact exception because I forgot to activate the virtual environment.

Do you mean any specific syntax for wildcards? Usually * stands for "one or many" characters and ? stands for one.

The simplest way probably is to translate a wildcard expression into a regular expression, then use that for filtering the results.

You can also replace "-moz-user-select:none" with "-moz-user-select:inherit". This will inherit the style value from any parent style or from the default style if no parent style was defined.

As of late April 2009, Microsoft has discontinued all previous versions of Visual Studio Express, including 2005. It is no longer possible to obtain these previous versions from the Microsoft website.

From Here

This website has some nice examples for using spring's RestTemplate. Here is a code example of how it can work to get a simple object:

private static void getEmployees()
{
    final String uri = "http://localhost:8080/springrestexample/employees.xml";

    RestTemplate restTemplate = new RestTemplate();
    String result = restTemplate.getForObject(uri, String.class);

    System.out.println(result);
}

Image to Data:-

    if let img = UIImage(named: "xxx.png") {
        let pngdata = img.pngData()
    }

   if let img = UIImage(named: "xxx.jpeg") {
        let jpegdata = img.jpegData(compressionQuality: 1)
    }

Data to Image:-

 let image = UIImage(data: pngData)

More correct create DTO for API queries, for example entityDTO:

1. Default response OK with list of entities:

@GetMapping(produces=MediaType.APPLICATION_JSON_VALUE)
@ResponseStatus(HttpStatus.OK)
public List<EntityDto> getAll() {
    return entityService.getAllEntities();
}

But if you need return different Map parameters you can use next two examples
2. For return one parameter like map:

@GetMapping(produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> getOneParameterMap() {
    return ResponseEntity.status(HttpStatus.CREATED).body(
            Collections.singletonMap("key", "value"));
}

3. And if you need return map of some parameters(since Java 9):

@GetMapping(produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> getSomeParameters() {
    return ResponseEntity.status(HttpStatus.OK).body(Map.of(
            "key-1", "value-1",
            "key-2", "value-2",
            "key-3", "value-3"));
}

int w =0 , l =0, d=0, i=0;
    Scanner sc = new Scanner(System.in);

// try tentimes
    while (i<10) {


        System.out.println("scissor(1) ,Rock(2),Paper(3) ");
        int n = sc.nextInt();
        int m =(int)(Math.random()*3+1);


        if(n==m){

            System.out.println("Com:"+m +"so>>> " + "draw");
            d++;


        }else if ((n-1)%3==(m%3)){
            w++;
            System.out.println("Com:"+m +"so>>> " +"win");
        }
        else if(n >=4 )
        {
            System.out.println("pleas enter correct number)");


    }
        else {
            System.out.println("Com:"+m +"so>>> " +"lose");
            l++;

        }
        i++;

Here is my implementation in C#:

    public static PointF PointOnCircle(float radius, float angleInDegrees, PointF origin)
    {
        // Convert from degrees to radians via multiplication by PI/180        
        float x = (float)(radius * Math.Cos(angleInDegrees * Math.PI / 180F)) + origin.X;
        float y = (float)(radius * Math.Sin(angleInDegrees * Math.PI / 180F)) + origin.Y;

        return new PointF(x, y);
    }

Try using the command: git status

From C++14 using std and also its numeric literals:

#include <chrono>
#include <thread>

using namespace std::chrono;

std::this_thread::sleep_for(123ms);

Depending on which database you're using...

select yr, count(*) num from ...
order by num desc

Most of my experience is in Sybase, which uses some different syntax than other DBs. But in this case, you're naming your count column, so you can sort it, descending order. You can go a step further, and restrict your results to the first 10 rows (to find his 10 busiest years).

You can set this value in a layout xml file using android:divider="#FF0000". If you are changing the colour/drawable, you have to set/reset the height of the divider too.

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content">

  <ListView 
    android:id="@+id/android:list"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:divider="#FFCC00"
    android:dividerHeight="4px"/>

</LinearLayout>

You are referring to the section "2.3.5 Deploying the demo app" of this "Ruby on Rails Tutorial ":

In section 2.3.1 Planning the application, note that they did:

$ git remote add origin [email protected]:<username>/demo_app.git
$ git push origin master

That is why a simple git push worked (using here an ssh address).
Did you follow that step and made that first push?

 www.github.com/levelone/demo_app

wouldn't be a writable URI for pushing to a GitHub repo.

https://[email protected]/levelone/demo_app.git

should be more appropriate.
Check what git remote -v returns, and if you need to replace the remote address, as described in GitHub help page, use git remote --set-url.

git remote set-url origin https://[email protected]/levelone/demo_app.git
or 
git remote set-url origin [email protected]:levelone/demo_app.git

Why not simply

var item = $('.field-item');
for (var i = 0; i <= item.length; i++) {
       if ($(item[i]).text() == 'someText') {
             $(item[i]).addClass('thisClass');
             //do some other stuff here
          }
     }

Detailed Step by Step instructions I followed to achieve this

• Download bouncycastle JAR from http://repo2.maven.org/maven2/org/bouncycastle/bcprov-ext-jdk15on/1.46/bcprov-ext-jdk15on-1.46.jar or take it from the "doc" folder.
• Configure BouncyCastle for PC using one of the below methods.
  • Adding the BC Provider Statically (Recommended)
    • Copy the bcprov-ext-jdk15on-1.46.jar to each
      • D:\tools\jdk1.5.0_09\jre\lib\ext (JDK (bundled JRE)
      • D:\tools\jre1.5.0_09\lib\ext (JRE)
      • C:\ (location to be used in env variable)
    • Modify the java.security file under
      • D:\tools\jdk1.5.0_09\jre\lib\security
      • D:\tools\jre1.5.0_09\lib\security
      • and add the following entry
        • security.provider.7=org.bouncycastle.jce.provider.BouncyCastleProvider
    • Add the following environment variable in "User Variables" section
      • CLASSPATH=%CLASSPATH%;c:\bcprov-ext-jdk15on-1.46.jar
  • Add bcprov-ext-jdk15on-1.46.jar to CLASSPATH of your project and Add the following line in your code
    • Security.addProvider(new BouncyCastleProvider());
• Generate the Keystore using Bouncy Castle
  • Run the following command
    • keytool -genkey -alias myproject -keystore C:/myproject.keystore -storepass myproject -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider
  • This generates the file C:\myproject.keystore
  • Run the following command to check if it is properly generated or not
    • keytool -list -keystore C:\myproject.keystore -storetype BKS

• Configure BouncyCastle for TOMCAT

  • Open D:\tools\apache-tomcat-6.0.35\conf\server.xml and add the following entry

    • <Connector port="8443" keystorePass="myproject" alias="myproject" keystore="c:/myproject.keystore" keystoreType="BKS" SSLEnabled="true" clientAuth="false" protocol="HTTP/1.1" scheme="https" secure="true" sslProtocol="TLS" sslImplementationName="org.bouncycastle.jce.provider.BouncyCastleProvider"/>

  • Restart the server after these changes.

• Configure BouncyCastle for Android Client
  • No need to configure since Android supports Bouncy Castle Version 1.46 internally in the provided "android.jar".
  • Just implement your version of HTTP Client (MyHttpClient.java can be found below) and set the following in code
    • SSLSocketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
  • If you don't do this, it gives an exception as below
    • javax.net.ssl.SSLException: hostname in certificate didn't match: <192.168.104.66> !=
  • In production mode, change the above code to
    • SSLSocketFactory.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);

        } catch (Exception e) {
            throw new AssertionError(e);
        }
    }
}

How to invoke the above code in your Activity class:

DefaultHttpClient client = new MyHttpClient(getApplicationContext());
HttpResponse response = client.execute(...);

Combine round and ceiling to get a proper round up.

select ceiling(round(984.375000), 0)) => 984

while

select round(984.375000, 0) => 984.000000

and

select ceil (984.375000) => 985

Use sleep like so:

sleep 2

That'll sleep for 2 seconds.

Be careful to give an argument. If you just run sleep, the process will sleep forever. (This is useful when you want a thread to sleep until it's woken.)

I've found this page on their github repo, I'll just paste the content here.

Recommended approach for saving a model

There are two main approaches for serializing and restoring a model.

The first (recommended) saves and loads only the model parameters:

torch.save(the_model.state_dict(), PATH)

Then later:

the_model = TheModelClass(*args, **kwargs)
the_model.load_state_dict(torch.load(PATH))

The second saves and loads the entire model:

torch.save(the_model, PATH)

Then later:

the_model = torch.load(PATH)

However in this case, the serialized data is bound to the specific classes and the exact directory structure used, so it can break in various ways when used in other projects, or after some serious refactors.

I tried CancellationTokenSource but i can't do this. And i did do this with my own way. And it works.

                {
                //Do stuff.
                }

                try
                {
                //Do stuff.
                }
                catch (Exception ex)
                {
                //Do stuff.
                }
                if (IsStopRequested) //3-)This is important. The control of the task stopping request. Must be true and in inside.
                {
                    return messageText = "Task stopped."; //4-) And so return and exit the code and task.
                }
                if (Connected)
                {
                //Do stuff.
                }
                if (count == 19)
                {
                //Do stuff.
                }
            }
            return messageText;
        }
    }
}

And another class of the calling the method:

namespace Blokick.Views
{
    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class MessagePerson : ContentPage
    {
        SignalRConnectProvider signalR = new SignalRConnectProvider();

        public MessagePerson()
        {
            InitializeComponent();

            signalR.IsStopRequested = true; // 2-) And this. Make true if running the task and go inside if statement of the IsStopRequested property.

            if (signalR.ChatHubProxy != null)
            {
                 signalR.Disconnect();
            }

            LoadSignalRMessage();
        }
    }
}

Some people, like me, will benefit from using the :focus-within pseudo-class.

Using it will apply the css you want to a div, for instance.

However, it is too slow on running

Yes, I've had the same problem. Some of the file downloads are extremely slow (or at least they have been in the last couple of days). If you want to download everything there's not a lot you can do about that.

The result is that nothing in folder build-tools, and I want is aapt and apkbuilder, since I want to build apk from command line without ant.

Did you let it run to completion?

One thing you can do is filter the packages that are being downloaded using the -t switch.

For example:

tools/android update sdk --no-ui -t platform-tool

When I tried this the other day I got version 18.0.0 of the build tools installed. For some reason the latest version 18.0.1 is not included by this filter and the only way to get it was to install everything with the --all switch.

Here are two more ways to write a pure PowerShell function to join an arbitrary number of components into a path.

This first function uses a single array to store all of the components and then a foreach loop to combine them:

function Join-Paths {
    Param(
        [Parameter(mandatory)]
        [String[]]
        $Paths
    )
    $output = $Paths[0]
    foreach($path in $Paths[1..$Paths.Count]) {
        $output = Join-Path $output -ChildPath $path
    }
    $output
}

Because the path components are elements in an array and all part of a single argument, they must be separated by commas. Usage is as follows:

PS C:\> Join-Paths 'C:', 'Program Files', 'Microsoft Office'
C:\Program Files\Microsoft Office

A more minimalist way to write this function is to use the built-in $args variable, and then collapse the foreach loop into a single line using Mike Fair's method.

function Join-Paths2 {
    $path = $args[0]
    $args[1..$args.Count] | %{ $path = Join-Path $path $_ }
    $path
}

Unlike the previous version of the function, each path component is a separate argument, so only a space is necessary to separate the arguments:

PS C:\> Join-Paths2 'C:' 'Program Files' 'Microsoft Office'
C:\Program Files\Microsoft Office

I solved this problem without deleting any keys. Here's how:

1. My device was connected to my computer via USB
2. I made sure Eclipse and android device monitor weren't running.
3. Typed at the commandline prompt: adb kill-server
4. Typed at the commandline prompt: adb start-server
5. After adb was restarted, I got a prompt on my device to authorize which I allowed.

My alias settings in ~/.zshrc file for git diff:

alias gdf='git diff HEAD{'^',}' # diff between your recent tow commits

Thanks @Jinmiao Luo

git diff HEAD~2 HEAD

complete change between latest 2nd commit and current.

HEAD is convenient

You can use get_cfg_var('cfg_file_path') for that:

To check whether the system is using a configuration file, try retrieving the value of the cfg_file_path configuration setting. If this is available, a configuration file is being used.

var_dump( get_cfg_var('cfg_file_path') );

And you can simply set the location of the php.ini. You're using the command line version, so using the -c parameter you can specifiy the location, e.g.

php -c /home/me/php.ini -f /home/me/test.php

You can access the full uri/url with 'document.referrer'

Here's a solution using a lineJoin to round the corners. Works if you just need a solid shape but not so much if you need a thin border that's smaller than the border radius.

    function roundedRect(ctx, options) {

        ctx.strokeStyle = options.color;
        ctx.fillStyle = options.color;
        ctx.lineJoin = "round";
        ctx.lineWidth = options.radius;

        ctx.strokeRect(
            options.x+(options.radius*.5),
            options.y+(options.radius*.5),
            options.width-options.radius,
            options.height-options.radius
        );

        ctx.fillRect(
            options.x+(options.radius*.5),
            options.y+(options.radius*.5),
            options.width-options.radius,
            options.height-options.radius
        );

        ctx.stroke();
        ctx.fill();

    }

    const canvas = document.getElementsByTagName("CANVAS")[0];
    let ctx = canvas.getContext('2d');

    roundedRect(ctx, {
        x: 10,
        y: 10,
        width: 200,
        height: 100,
        radius: 10,
        color: "red"
    });

Use this property for an Image view such as,

1) android:scaleType="fitXY" - It means the Images will be stretched to fit all the sides of the parent that is based on your ImageView!

2) By using above property, it will affect your Image resolution so if you want to maintain the resolution then add a property such as android:scaleType="centerInside".

@CemKalyoncu: Thanks for the great answer!

I also adapted it slightly to make it more like the Array.splice method (and took @Ates' note into consideration):

spliceString=function(string, index, numToDelete, char) {
      return string.substr(0, index) + char + string.substr(index+numToDelete);
   }

var myString="hello world!";
spliceString(myString,myString.lastIndexOf('l'),2,'mhole'); // "hello wormhole!"

Also relevant, but specially to excel, look at this answer and this other one that suggests, inserting a line at the beginning of the CSV with

"sep=,"

To inform excel which separator to expect

macOS Sierra 10.12.6. Wasn't able to install anything through pip (python installed through homebrew). All the answers above didn't work.

Eventually, upgrade from python 3.5 to 3.6 worked.

brew update
brew doctor #(in case you see such suggestion by brew)

then follow any additional suggestions by brew, i.e. overwrite link to python.

Also try changing from this:

    SELECT * FROM table WHERE Contains(Column, "test") > 0;

To this:

    SELECT * FROM table WHERE Contains(Column, '"*test*"') > 0;

The former will find records with values like "this is a test" and "a test-case is the plan".

The latter will also find records with values like "i am testing this" and "this is the greatest".

you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:

#!/bin/sh

OPTIONS=$(getopt -o hf:gb -l help,file:,foo,bar -- "$@")

if [ $? -ne 0 ]; then
  echo "getopt error"
  exit 1
fi

eval set -- $OPTIONS

while true; do
  case "$1" in
    -h|--help) HELP=1 ;;
    -f|--file) FILE="$2" ; shift ;;
    -g|--foo)  FOO=1 ;;
    -b|--bar)  BAR=1 ;;
    --)        shift ; break ;;
    *)         echo "unknown option: $1" ; exit 1 ;;
  esac
  shift
done

if [ $# -ne 0 ]; then
  echo "unknown option(s): $@"
  exit 1
fi

echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"

While working with Spring Boot application, it is difficult to get the classpath resources using resource.getFile() when it is deployed as JAR as I faced the same issue. This scan be resolved using Stream which will find out all the resources which are placed anywhere in classpath.

Below is the code snippet for the same -

ClassPathResource classPathResource = new ClassPathResource("fileName");
InputStream inputStream = classPathResource.getInputStream();
content = IOUtils.toString(inputStream);

As @Josh said, the correct answer is:

int column = 0,
    row = 0,
    index = 0;

You'll need to watch out for the same thing with pointers. This:

int* a, b, c;

Is equivalent to:

int *a;
int b;
int c;

Summary:

Javascript uses a mechanism which is called prototypal inheritance. Prototypal inheritance is used when looking up a property on an object. When we are extending properties in javascript we are inheriting these properties from an actual object. It works in the following manner:

1. When an object property is requested, (e.g myObj.foo or myObj['foo']) the JS engine will first look for that property on the object itself
2. When this property isn't found on the object itself it will climb the prototype chain look at the prototype object. If this property is also not found here it will keep climbing the prototype chain until the property is found. If the property is not found it will throw a reference error.

When we want to extend from a object in javascript we can simply link this object in the prototype chain. There are numerous ways to achieve this, I will describe 2 commonly used methods.

Examples:

1. Object.create()

Object.create() is a function that takes an object as an argument and creates a new object. The object which was passed as an argument will be the prototype of the newly create object. For example:

// prototype of the dog_x000D_
const dogPrototype = {_x000D_
  woof: function () { console.log('woof'); }_x000D_
}_x000D_
_x000D_
// create 2 dog objects, pass prototype as an argument_x000D_
const fluffy = Object.create(dogPrototype);_x000D_
const notFluffy = Object.create(dogPrototype);_x000D_
_x000D_
// both newly created object inherit the woof _x000D_
// function from the dogPrototype_x000D_
fluffy.woof();_x000D_
notFluffy.woof();

2. Explicitly setting the prototype property

When creating objects using constructor functions, we can set add properties to its prototype object property. Objects which are created form a constructor function when using the new keyword, have their prototype set to the prototype of the constructor function. For example:

// Constructor function object_x000D_
function Dog (name) {_x000D_
   name = this.name;_x000D_
}_x000D_
_x000D_
// Functions are just objects_x000D_
// All functions have a prototype property_x000D_
// When a function is used as a constructor (with the new keyword)_x000D_
// The newly created object will have the consturctor function's_x000D_
// prototype as its prototype property_x000D_
Dog.prototype.woof = function () {_x000D_
  console.log('woof');_x000D_
}_x000D_
_x000D_
// create a new dog instance_x000D_
const fluffy = new Dog('fluffyGoodBoyyyyy');_x000D_
// fluffy inherits the woof method_x000D_
fluffy.woof();_x000D_
_x000D_
// can check the prototype in the following manner_x000D_
console.log(Object.getPrototypeOf(fluffy));

A pull request is just that: a request to merge one branch into another.

Your pull request doesn't "contain" anything, it's just a marker saying "please merge this branch into that one".

The set of changes the PR shows in the web UI is just the changes between the target branch and your feature branch. To modify your pull request, you must modify your feature branch, probably with a force push to the feature branch.

In your case, you'll probably want to amend your commit. Not sure about your exact situation, but some combination of interactive rebase and add -p should sort you out.

There is a way to change the package name easily in Eclipse. Right click on your project, scroll down to Android Tools, and then click on Rename Application Package.

I just now faced this issue while trying to restart XAMPP Apache.

What you can do to solve this is:

1. download PHP5.dll from http://originaldll.com/file/php5.dll/30704.html
2. Copy the downloaded php5.dll to C:\xampp\php
3. Start APACHE and MySql from XAMPP control panel

Hope my solution solves your problem.

Thank You!

Setting up log4j logging for Tomcat is pretty simple. The following is quoted from http://tomcat.apache.org/tomcat-5.5-doc/logging.html :

1. Create a file called log4j.properties with the following content and save it into common/classes.

             log4j.rootLogger=DEBUG, R 
             log4j.appender.R=org.apache.log4j.RollingFileAppender 
             log4j.appender.R.File=${catalina.home}/logs/tomcat.log 
             log4j.appender.R.MaxFileSize=10MB 
             log4j.appender.R.MaxBackupIndex=10 
             log4j.appender.R.layout=org.apache.log4j.PatternLayout 
             log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
   

2. Download Log4J (v1.2 or later) and place the log4j jar in $CATALINA_HOME/common/lib.

3. Download Commons Logging and place the commons-logging-x.y.z.jar (not commons-logging-api-x.y.z.jar) in $CATALINA_HOME/common/lib with the log4j jar.
4. Start Tomcat

I feel this question need a bit more details. My answer is inspired from the Android Programming, The Big Nerd Ranch Guide (2nd edition).

By default, JavaScript is off in WebView. You do not always need to have it on, but for some apps, might do require it.

Loading the URL has to be done after configuring the WebView, so you do that last. Before that, you turn JavaScript on by calling getSettings() to get an instance of WebSettings and calling WebSettings.setJavaScriptEnabled(true). WebSettings is the first of the three ways you can modify your WebView. It has various properties you can set, like the user agent string and text size.

After that, you configure your WebViewClient. WebViewClient is an event interface. By providing your own implementation of WebViewClient, you can respond to rendering events. For example, you could detect when the renderer starts loading an image from a particular URL or decide whether to resubmit a POST request to the server.

WebViewClient has many methods you can override, most of which you will not deal with. However, you do need to replace the default WebViewClient’s implementation of shouldOverrideUrlLoading(WebView, String). This method determines what will happen when a new URL is loaded in the WebView, like by pressing a link. If you return true, you are saying, “Do not handle this URL, I am handling it myself.” If you return false, you are saying, “Go ahead and load this URL, WebView, I’m not doing anything with it.”

The default implementation fires an implicit intent with the URL, just like you did earlier. Now, though, this would be a severe problem. The first thing some Web Applications does is redirect you to the mobile version of the website. With the default WebViewClient, that means that you are immediately sent to the user’s default web browser. This is just what you are trying to avoid. The fix is simple – just override the default implementation and return false.

Use WebChromeClient to spruce things up Since you are taking the time to create your own WebView, let’s spruce it up a bit by adding a progress bar and updating the toolbar’s subtitle with the title of the loaded page.

To hook up the ProgressBar, you will use the second callback on WebView: WebChromeClient.

WebViewClient is an interface for responding to rendering events; WebChromeClient is an event interface for reacting to events that should change elements of chrome around the browser. This includes JavaScript alerts, favicons, and of course updates for loading progress and the title of the current page.

Hook it up in onCreateView(…). Using WebChromeClient to spruce things up Progress updates and title updates each have their own callback method, onProgressChanged(WebView, int) and onReceivedTitle(WebView, String). The progress you receive from onProgressChanged(WebView, int) is an integer from 0 to 100. If it is 100, you know that the page is done loading, so you hide the ProgressBar by setting its visibility to View.GONE.

Use an "Or"

Select SUM(CAmount) as PaymentAmount 
from TableOrderPayment 
where (CPaymentType='Check' Or CPaymentType='Cash')
   and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
   and CStatus='" & "Active" & "'"

or an "IN"

Select SUM(CAmount) as PaymentAmount 
from TableOrderPayment 
where CPaymentType IN ('Check', 'Cash')
   and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
   and CStatus='" & "Active" & "'"

In MySQL:

create table temp as select * from original_table

Recently came upon a case where this was not true, TI C28x boards can have a sizeof pointer == 1, since a byte for those boards is 16-bits, and pointer size is 16 bits. To make matters more confusing, they also have far pointers which are 22-bits. I'm not really sure what sizeof far pointer would be.

In general, DSP boards can have weird integer sizes.

So pointer sizes can still be weird in 2020 if you are looking in weird places

Inline styling does not support pseudos or at-rules (e.g., @media). Recommendations range from reimplement CSS features in JavaScript for CSS states like :hover via onMouseEnter and onMouseLeave to using more elements to reproduce pseudo-elements like :after and :before to just use an external stylesheet.

Personally dislike all of those solutions. Reimplementing CSS features via JavaScript does not scale well -- neither does adding superfluous markup.

Imagine a large team wherein each developer is recreating CSS features like :hover. Each developer will do it differently, as teams grow in size, if it can be done, it will be done. Fact is with JavaScript there are about n ways to reimplement CSS features, and over time you can bet on every one of those ways being implemented with the end result being spaghetti code.

So what to do? Use CSS. Granted you asked about inline styling going to assume you're likely in the CSS-in-JS camp (me too!). Have found colocating HTML and CSS to be as valuable as colocating JS and HTML, lots of folks just don't realise it yet (JS-HTML colocation had lots of resistance too at first).

Made a solution in this space called Style It that simply lets your write plaintext CSS in your React components. No need to waste cycles reinventing CSS in JS. Right tool for the right job, here is an example using :after:

• get your App id from headline,
• get Client Token from app Settings -> Advanced. There is also Native or desktop app? question/config. I turn it on.
• Add product (just click on Add product and then Get started on Facebook login. Move back to your app config, click to newly added Facebook login and you'll see your Login from Devices config.

Xfce/Thunar solution is basically the same as Gnome/Nautilus:

Simply type sftp://yourhost/ to address line in Thunar (You can get there by Ctrl + L)

(The authorization is identical to ssh/scp, i.e. with proper use of ~/.ssh/config, keys and ssh-agent, you can achieve decent ease and security: server alias + no passwords asked.)

The simplest way, based on @nosklo's comment and answer:

import tempfile
tmp = tempfile.mkdtemp()

But if you want to manually control the creation of the directories:

import os
from tempfile import gettempdir
tmp = os.path.join(gettempdir(), '.{}'.format(hash(os.times())))
os.makedirs(tmp)

That way you can easily clean up after yourself when you are done (for privacy, resources, security, whatever) with:

from shutil import rmtree
rmtree(tmp, ignore_errors=True)

This is similar to what applications like Google Chrome and Linux systemd do. They just use a shorter hex hash and an app-specific prefix to "advertise" their presence.

For your reference, I believe you can "hard cut" commits out of your current branch not only with git reset --hard, but also with the following command:

git checkout -B <branch-name> <SHA>

In fact, if you don't care about checking out, you can set the branch to whatever you want with:

git branch -f <branch-name> <SHA>

This would be a programmatic way to remove commits from a branch, for instance, in order to copy new commits to it (using rebase).

Suppose you have a branch that is disconnected from master because you have taken sources from some other location and dumped it into the branch.

You now have a branch in which you have applied changes, let's call it "topic".

You will now create a duplicate of your topic branch and then rebase it onto the source code dump that is sitting in branch "dump":

git branch topic_duplicate topic
git rebase --onto dump master topic_duplicate

Now your changes are reapplied in branch topic_duplicate based on the starting point of "dump" but only the commits that have happened since "master". So your changes since master are now reapplied on top of "dump" but the result ends up in "topic_duplicate".

You could then replace "dump" with "topic_duplicate" by doing:

git branch -f dump topic_duplicate
git branch -D topic_duplicate

Or with

git branch -M topic_duplicate dump

Or just by discarding the dump

git branch -D dump

Perhaps you could also just cherry-pick after clearing the current "topic_duplicate".

What I am trying to say is that if you want to update the current "duplicate" branch based off of a different ancestor you must first delete the previously "cherrypicked" commits by doing a git reset --hard <last-commit-to-retain> or git branch -f topic_duplicate <last-commit-to-retain> and then copying the other commits over (from the main topic branch) by either rebasing or cherry-picking.

Rebasing only works on a branch that already has the commits, so you need to duplicate your topic branch each time you want to do that.

Cherrypicking is much easier:

git cherry-pick master..topic

So the entire sequence will come down to:

git reset --hard <latest-commit-to-keep>
git cherry-pick master..topic

When your topic-duplicate branch has been checked out. That would remove previously-cherry-picked commits from the current duplicate, and just re-apply all of the changes happening in "topic" on top of your current "dump" (different ancestor). It seems a reasonably convenient way to base your development on the "real" upstream master while using a different "downstream" master to check whether your local changes also still apply to that. Alternatively you could just generate a diff and then apply it outside of any Git source tree. But in this way you can keep an up-to-date modified (patched) version that is based on your distribution's version while your actual development is against the real upstream master.

So just to demonstrate:

• reset will make your branch point to a different commit (--hard also checks out the previous commit, --soft keeps added files in the index (that would be committed if you commit again) and the default (--mixed) will not check out the previous commit (wiping your local changes) but it will clear the index (nothing has been added for commit yet)
• you can just force a branch to point to a different commit
• you can do so while immediately checking out that commit as well
• rebasing works on commits present in your current branch
• cherry-picking means to copy over from a different branch

Hope this helps someone. I was meaning to rewrite this, but I cannot manage now. Regards.

1. Install mingw64 from https://sourceforge.net/projects/mingw-w64/. Avoid program files/(x86) folder for installation. Ex. c:/mingw-w64
2. Download pkg-config__win64.zip from here
3. Extract above zip file and copy paste all the files from pkg-config/bin folder to mingw-w64. In my case its 'C:\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin'
4. Now set path = C:\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin taddaaa you are done.

If you find any security issue then follow steps as well

1. Search for windows defender security center in system
2. Navigate to apps & browser control> Exploit protection settings> Program setting> Click on '+add program customize'
3. Select add program by name
4. Enter program name: pkgconf.exe
5. OK
6. Now check all the settings and set it all the settings to off and apply.

Thats DONE!

Probably wdlen starts with a value >=2, so in the second case the loop condition is initially false and the loop is never entered.

In the second case the loop body is executed before the wdlen<2 condition is checked for the first time, so the printf/scanf is executed at least once.

\s matches whitespace (spaces, tabs and new lines). \S is negated \s.

If you are using ES6 features and you're in an async function, you can effectively halt the code execution for a certain time with this function:

const delay = millis => new Promise((resolve, reject) => {
  setTimeout(_ => resolve(), millis)
});

This is how you use it:

await delay(5000);

It will stall for the requested amount of milliseconds, but only if you're in an async function. Example below:

const myFunction = async function() {
  // first code block ...

  await delay(5000);

  // some more code, executed 5 seconds after the first code block finishes
}

There are lot of factors , first see whether server returns the result, then check between server and client.

rectify them from server side first,then check the writing condition between server and client !

server side rectify the time outs between the datalayer and server from client side rectify the time out and number of available connections !

In my case I was using jackson-databind-2.8.8.jar that is not compatible with JDK 1.6 I need to use so Spring wasn't loading this converter. I downgraded the version and it works now.

The big difference is start from where they are coming from, so constructor is the constructor of your class in JavaScript, on the other side, getInitialState is part of the lifecycle of React . The constructor method is a special method for creating and initializing an object created with a class.

if you don't have a good copy of your php5.ini file in your home directory (a predicament that I recently found myself in), you'll need to follow a little multi-step process to make your changes.

1. Create a little code snippet to look at the output of the phpinfo() call. This is simple, and there are multiple web-sites that describe this process.

2. Examine the output of phpinfo() for the row which contains Configuration File (php.ini) Path. Mine was in /usr/local/lib, but your's may be a different path (depends on hosting level purchased).

3. GoDaddy will NOT simply copy this file into your home directory for you --as silly as that sounds! But, you can write a little php program to copy this php.ini file into your home directory. The guy at https://www.jabari-holder.com/blog/how-to-get-godaddys-php5-ini-file/ has a drop-box with this code snippet, if you care to use it. Just take care to modify two things:

   • a. change the path you read 'from' to match the path you uncovered in Step 2.

   • b. change the output file-name to something of your choosing. You're going to re-name this file in a later step anyway. Let's call our copied file Foo.ini (but it can be anything).

4. Rename Foo.ini to .user.ini (for most GoDaddy account types).

Option 1
You didn't say much about your environment, but assuming you have it available you could use a PowerShell script; one example is here. The essence of this is:

$smtp = New-Object Net.Mail.SmtpClient("ho-ex2010-caht1.exchangeserverpro.net")
$smtp.Send("[email protected]","[email protected]","Test Email","This is a test")

You could then launch the script from the command line as per this example:

powershell.exe -noexit c:\scripts\test.ps1

Note that PowerShell 2.0, which is installed by default on Windows 7 and Windows Server 2008R2, includes a simpler Send-MailMessage command, making things easier.

Option 2
If you're prepared to use third-party software, is something line this SendEmail command-line tool. It depends on your target environment, though; if you're deploying your batch file to multiple machines, that will obviously require inclusion (but not formal installation) each time.

Option 3
You could drive Outlook directly from a VBA script, which in turn you would trigger from a batch file; this would let you send an email using Outlook itself, which looks to be closest to what you're wanting. There are two parts to this; first, figure out the VBA scripting required to send an email. There are lots of examples for this online, including from Microsoft here. Essence of this is:

Sub SendMessage(DisplayMsg As Boolean, Optional AttachmentPath)
    Dim objOutlook As Outlook.Application
    Dim objOutlookMsg As Outlook.MailItem
    Dim objOutlookRecip As Outlook.Recipient
    Dim objOutlookAttach As Outlook.Attachment

    Set objOutlook = CreateObject("Outlook.Application")
    Set objOutlookMsg  = objOutlook.CreateItem(olMailItem)

    With objOutlookMsg
        Set objOutlookRecip = .Recipients.Add("Nancy Davolio")
        objOutlookRecip.Type = olTo
        ' Set the Subject, Body, and Importance of the message.
        .Subject = "This is an Automation test with Microsoft Outlook"
        .Body = "This is the body of the message." &vbCrLf & vbCrLf
        .Importance = olImportanceHigh  'High importance

        If Not IsMissing(AttachmentPath) Then
            Set objOutlookAttach = .Attachments.Add(AttachmentPath)
        End If

        For Each ObjOutlookRecip In .Recipients
            objOutlookRecip.Resolve
        Next

        .Save
        .Send
    End With
    Set objOutlook = Nothing
End Sub

Then, launch Outlook from the command line with the /autorun parameter, as per this answer (alter path/macroname as necessary):

C:\Program Files\Microsoft Office\Office11\Outlook.exe" /autorun macroname

Option 4
You could use the same approach as option 3, but move the Outlook VBA into a PowerShell script (which you would run from a command line). Example here. This is probably the tidiest solution, IMO.

Similar problem here: Given a string and a list of keywords, detect which, if any, of the keywords are contained in the string.

Recommendations from this thread suggest stringr's str_detect and grepl. Here are the benchmarks from the microbenchmark package:

Using

map_keywords = c("once", "twice", "few")
t = "yes but only a few times"

mapper1 <- function (x) {
  r = str_detect(x, map_keywords)
}

mapper2 <- function (x) {
  r = sapply(map_keywords, function (k) grepl(k, x, fixed = T))
}

and then

microbenchmark(mapper1(t), mapper2(t), times = 5000)

we find

Unit: microseconds
       expr    min     lq     mean  median      uq      max neval
 mapper1(t) 26.401 27.988 31.32951 28.8430 29.5225 2091.476  5000
 mapper2(t) 19.289 20.767 24.94484 23.7725 24.6220 1011.837  5000

As you can see, over 5,000 iterations of the keyword search using str_detect and grepl over a practical string and vector of keywords, grepl performs quite a bit better than str_detect.

The outcome is the boolean vector r which identifies which, if any, of the keywords are contained in the string.

Therefore, I recommend using grepl to determine if any keywords are in a string.

Here is the non-command line method:

In Windows 7 or 10, type environment into the start menu search box, and select Edit the system environment variables.

Alternatively, navigate to Control Panel\System and Security\System, and click Advanced system settings

This should open up the System properties dialog box with the Advanced tab selected. At the bottom, you will see an Environment Variables... button. Click this.

The Environment Variables Dialog Box will open.

At the bottom, under System variables, select New...This will open the New System Variable dialog box.

Enter the variable name and value, and click OK.

You will need to close all cmd prompts and restart your server for the new variable to be available to process.env. If it still doesn't show up, restart your machine.

Remember to put not only the tag but also the repository in which that tag is, this way:

docker images
REPOSITORY                                TAG                       IMAGE ID            CREATED             SIZE
elixir                                    1.7-centos7_3             e15e6bf57262        20 hours ago        925MB

You should reference it this way:

elixir:1.7-centos7_3

You have use to repeat-y as style="background-repeat:repeat-y;width: 200px;" instead of style="repeat-y".

Try this inside the image tag or you can use the below css for the div

.div_backgrndimg
{
    background-repeat: repeat-y;
    background-image: url("/image/layout/lotus-dreapta.png");
    width:200px;
}

Combine them. Literally combine them; attach them together without any punctuation.

$('.myclass[reference="12345"]')

Your first selector looks for elements with the attribute value, contained in elements with the class.
The space is being interpreted as the descendant selector.

Your second selector, like you said, looks for elements with either the attribute value, or the class, or both.
The comma is being interpreted as the multiple selector operator — whatever that means (CSS selectors don't have a notion of "operators"; the comma is probably more accurately known as a delimiter).

tl;dr - I'm not sure that it would be possible for the .NET Core developers to supply a cross-platform GUI framework.

I feel like expecting a cross-platform GUI framework to be bundled into the official tooling (especially an old version of the tooling - you mention that you're running Visual Studio 2015 update 3) for an early version of .NET Core is a little premature.

GUI frameworks are really quite heavy, and dependent on the hardware abstractions already present on the host machine. On Windows, there is generally a single window manager (WM) and desktop environment (DE) used by most users, but on the many different distributions of Linux which are supported, there are any number of possible WMs and DEs - granted most users will either be using X-Server or Wayland in combination with KDE, GNOME or Xfce. But no Linux installation ever is the same.

The fact that the open source community can't really settle on a "standard" setup for a VM and DE means that it would be pretty difficult for the .NET Core developers to create a GUI framework which would work across all platforms and combinations of DEs and WMs.

A lot of folks here have some great suggestions (from use ASP.NET Core to builds a Web application and use a browser to listing a bunch of cross-platform frameworks). If you take a look at some of the mentioned cross platform GUI frameworks listed, you'll see how heavy they are.

However, there is light at the end of the tunnel as Miguel de Icaza showed off Xamarin running naively on Linux and macOS at .NET Conf this year (2017, if you're reading this in the future), so it might be worth trying that when it's ready.

(But you'll need to upgrade from Visual Studio 2015 to Visual Studio 2017 to access the .NET Core 2.0 features.)

OpenFileDialog fdlg = new OpenFileDialog();
fdlg.Title = "C# Corner Open File Dialog" ;
fdlg.InitialDirectory = @"c:\" ;
fdlg.Filter = "All files (*.*)|*.*|All files (*.*)|*.*" ;
fdlg.FilterIndex = 2 ;
fdlg.RestoreDirectory = true ;
if(fdlg.ShowDialog() == DialogResult.OK)
{
textBox1.Text = fdlg.FileName ;
}

In this code you can put your address in a text box.

Swift 4.2+

Starting with Swift 4.2 (with Xcode 10), just add protocol conformance to CaseIterable to benefit from allCases. To add this protocol conformance, you simply need to write somewhere:

extension Suit: CaseIterable {}

If the enum is your own, you may specify the conformance directly in the declaration:

enum Suit: String, CaseIterable { case spades = "?"; case hearts = "?"; case diamonds = "?"; case clubs = "?" }

Then the following code will print all possible values:

Suit.allCases.forEach {
    print($0.rawValue)
}

Compatibility with earlier Swift versions (3.x and 4.x)

If you need to support Swift 3.x or 4.0, you may mimic the Swift 4.2 implementation by adding the following code:

#if !swift(>=4.2)
public protocol CaseIterable {
    associatedtype AllCases: Collection where AllCases.Element == Self
    static var allCases: AllCases { get }
}
extension CaseIterable where Self: Hashable {
    static var allCases: [Self] {
        return [Self](AnySequence { () -> AnyIterator<Self> in
            var raw = 0
            var first: Self?
            return AnyIterator {
                let current = withUnsafeBytes(of: &raw) { $0.load(as: Self.self) }
                if raw == 0 {
                    first = current
                } else if current == first {
                    return nil
                }
                raw += 1
                return current
            }
        })
    }
}
#endif

Had this problem as well. Something was wrong with my CocoaPods installation. No pods other than KIF were installing properly. I followed the comments on this thread to be of help.

Basically, I needed to ensure that Build Active Architectures Only settings for both my project and the Pods project were equal.

You need math. Programming is nothing more than math. Any findings of theoretical physics does not become a practical(applicable) implication, unless they are explained in terms of mathematical solutions. None of those can be solved computationally if they cannot be interpreted on computers, and more specifically on programming languages. Different languages are thus designed to solve specific problems. But for the general purpose and wide spread programming languages like java, c, c++ much of our programming tasks involve repetitive(continuous) solution to same problems like extracting values from database, text files, putting them on windows(desktop, web), manipulating same values, sometimes accessing some data from similar devices(but given different brand names, different port and a headache) etc which does not involve more than unitary method, and algebra(counter, some logic), geometry(graphics) etc. So it depends what you are trying to solve.

glPolygonMode( GL_FRONT_AND_BACK, GL_LINE );

to switch on,

glPolygonMode( GL_FRONT_AND_BACK, GL_FILL );

to go back to normal.

Note that things like texture-mapping and lighting will still be applied to the wireframe lines if they're enabled, which can look weird.

It depends. If the main code is protected by an if as in:

if __name__ == '__main__':
    ...main code...

then no, you can't make Python execute that because you can't influence the automatic variable __name__.

But when all the code is in a function, then might be able to. Try

import myModule

myModule.main()

This works even when the module protects itself with a __all__.

from myModule import * might not make main visible to you, so you really need to import the module itself.
