Programs & Examples On #Overlap

With absolute or relative positioning, you can do all sorts of overlapping. You've probably want the logo to be styled as such:

div#logo {
  position: absolute;
  left: 100px; // or whatever
}

Note: absolute position has its eccentricities. You'll probably have to experiment a little, but it shouldn't be too hard to do what you want.

To have a query working in any locale settings, consider formatting the date yourself:

SELECT * 
  FROM testbed 
 WHERE start_date >= to_date('2012-01-01','YYYY-MM-DD')
   AND end_date <= to_date('2012-04-13','YYYY-MM-DD');

"If you perform subtraction x or y coordinates corresponding to the vertices of the two facing each rectangle, if the results are the same sign, the two rectangle do not overlap axes that" (i am sorry, i am not sure my translation is correct)

Your methods are missing the static keyword. Change

function getInstanceByName($name=''){

to

public static function getInstanceByName($name=''){

if you want to call them statically.

Note that static methods (and Singletons) are death to testability.

Also note that you are doing way too much work in the constructor, especially all that querying shouldn't be in there. All your constructor is supposed to do is set the object into a valid state. If you have to have data from outside the class to do that consider injecting it instead of pulling it. Also note that constructors cannot return anything. They will always return void so all these return false statements do nothing but end the construction.

The main alternative is:

• CodeRush, by DevExpress. Most consider either this or ReSharper the way to go. You cannot go wrong with either. Both have their fans, both are powerful, and both have talented teams constantly improving them. We have all benefited from the competition between these two. I won't repeat the many good discussions/comparisons about them that can be found on Stack Overflow and elsewhere.

Another alternative worth checking out:

• JustCode, by Telerik. This is new, still with kinks, but initial reports are positive. An advantage could be licensing with other Telerik products and integration with them. There are bundled licenses available that could make things cheaper / easier to handle.

Try to use like this: jdbc:jtds:sqlserver://127.0.0.1/dotcms; instance=instanceName

I don't know which version of mssql you are using, if it is express edition, default instance is sqlexpress

Do not forget check if SQL Server Browser service is running.

As alexpods says, there is no dedicated way to do this in ES6. However, for those interested, there is also a proposal for the bind operator which enables this sort of syntax:

function privateMethod() {
  return `Hello ${this.name}`;
}

export class Animal {
  constructor(name) {
    this.name = name;
  }
  publicMethod() {
    this::privateMethod();
  }
}

Once again, this is just a proposal. Your mileage may vary.

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

In Android Studio, Click on 'Tools' on the top tab bar of android studio

Tools >> Android >> SDK Manager >> Launch Standalone Sdk manager

there you can clearly see which platform tool is missing , then just install that and your adb will start working properly.In Image You Can see every thing

Below a fully functional method to get hard disk serial number:

public string GetHardDiskSerialNo()
    {
        ManagementClass mangnmt = new ManagementClass("Win32_LogicalDisk");
        ManagementObjectCollection mcol = mangnmt.GetInstances();
        string result = "";
        foreach (ManagementObject strt in mcol)
        {
            result += Convert.ToString(strt["VolumeSerialNumber"]);
        }
        return result;
    }

For bootstrap 3 datepicker. (Note the capital letters)

$("#datetimepicker").datetimepicker( {
  format: "YYYY",
  viewMode: "years"
});

Late to the party but I sometimes use this one-liner as an equivalent:

((Function<Value, Key>) Value::getKey).andThen(new HashSet<>()::add)::apply

The expression is a Predicate<Value> but since the map is inline, it works as a filter. This is of course less readable but sometimes it can be helpful to avoid the method.

you can also use this:

  SELECT DATEADD(day, DATEDIFF(day, 0, WeddingDate) /7*7, 0) AS weekstart,
         DATEADD(day, DATEDIFF(day, 6, WeddingDate-1) /7*7 + 7, 6) AS WeekEnd

After checking out my branch in Egit, I switched to the Java View, then used File-->Import, Git-->Projects from Git, then selected the top level maven directory. This was with Eclipse Kepler.

If you have to load a lot of data into tables on a regular basis, check out SQL Loader or external tables. Should be much faster than individual Inserts.

Just as an FYI, here is my working code:

src_dir = "C:\\temp\\CSV\\"
target_dir = "C:\\temp\\output2\\"
keyword = "KEYWORD"

for f in os.listdir(src_dir):
    file_name = os.path.join(src_dir, f)
    out_file = os.path.join(target_dir, f)
    with open(file_name, "r+") as fi, open(out_file, "w") as fo:
        for line in fi:
            if keyword not in line:
                fo.write(line)

Thanks again to everyone for all the great feedback!

Follow these steps:

1. Open Netbeans
2. Click File > New Project > JavaFX > JavaFX with existing sources
3. Click Next
4. Name the project
5. Click Next
6. Under Source Package Folders click Add Folder
7. Select the nbproject folder under the zip file you wish to upload (Note: you need to unzip the folder)
8. Click Next
9. All the files will be included but you can exclude some if you wish
10. Click Finish and the project should be there

If you don't have the source folder added do the following

1. Under your projects directory tree right click on Source Packages
2. Click New
3. Click Java Package and name it with the name of the package the source files have
4. Go to the directory location (i.e., using Windows Explorer not Netbeans) of those source files, highlight them all, then drag and drop them under that Java Package you just created
5. Click Run
6. Click Clean and Build Project

Now you can have fun and run the application.

You can include the script file directly in your page/master page, etc using:

 <script type="text/javascript" src="/scripts/jquery.min.js"></script> 

Us use a Content Delivery network like Google or Microsoft:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> 

or:

<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script>     

Best would be not using LinkedList at all, usually it is slower in all disciplines, and less handy. (When mainly inserting/deleting to the front, especially for big arrays LinkedList is faster)

Use ArrayList, and iterate with

int len = list.size();
for (int i = 0; i < len; i++) {
  Element ele = list.get(i);
}

Reset is trivial, just loop again.
If you insist on using an iterator, then you have to use a new iterator:

iter = list.listIterator();

(I saw only once in my life an advantage of LinkedList: i could loop through whith a while loop and remove the first element)

For me to sort this issue I had to go to Build, Execution, Deployment -> Build Tools -> Maven -> Importing and set JDK for import to JAVA_HOME! Then Reload all maven projects from the maven settings. All imports now work!!

Try this one to push basic authentication at url:

curl -i http://username:[email protected]/api/users -H "Authorization: Bearer mytoken123"
               ^^^^^^^^^^^^^^^^^^

If above one doesn't work, then you have nothing to do with it. So try the following alternates.

You can pass the token under another name. Because you are handling the authorization from your Application. So you can easily use this flexibility for this special purpose.

curl -i http://dev.myapp.com/api/users \
  -H "Authorization: Basic Ym9zY236Ym9zY28=" \
  -H "Application-Authorization: mytoken123"

Notice I have changed the header into Application-Authorization. So from your application catch the token under that header and process what you need to do.

Another thing you can do is, to pass the token through the POST parameters and grab the parameter's value from the Server side. For example passing token with curl post parameter:

-d "auth-token=mytoken123"

Usually, to get low level OS information you can call OS specific commands which give you the information you want with Runtime.exec() or read files such as /proc/* in Linux.

According to Apple’s user experience coding guide for mobile Safari, you can use the following to display a numeric keyboard in the iPhone browser:

<input type="text" pattern="[0-9]*" />

A pattern of \d* will also work.

The livereload plugin fails to serve cordova.js file and serves // mock cordova file during development.

FIX: You need go to node_modules/@ionic/app-scripts/dist/dev-server/serve-config.js

and replace

exports.ANDROID_PLATFORM_PATH = path.join('platforms', 'android', 'assets', 'www');

to

exports.ANDROID_PLATFORM_PATH = path.join('platforms', 'android', 'app', 'src', 'main', 'assets', 'www');

Note: This is Flask specific!

I know this post is quite old, but there are better methods of doing this in the newer versions of Flask using context processors.

Variables can easily be created:

@app.context_processor
def example():
    return dict(myexample='This is an example')

The above can be used in a Jinja2 template with Flask like so:

{{ myexample }}

(Which outputs This is an example)

As well as full fledged functions:

@app.context_processor
def utility_processor():
    def format_price(amount, currency=u'€'):
        return u'{0:.2f}{1}'.format(amount, currency)
    return dict(format_price=format_price)

The above when used like so:

{{ format_price(0.33) }}

(Which outputs the input price with the currency symbol)

Alternatively, you can use jinja filters, baked into Flask. E.g. using decorators:

@app.template_filter('reverse')
def reverse_filter(s):
    return s[::-1]

Or, without decorators, and manually registering the function:

def reverse_filter(s):
    return s[::-1]
app.jinja_env.filters['reverse'] = reverse_filter

Filters applied with the above two methods can be used like this:

{% for x in mylist | reverse %}
{% endfor %}

Yes, it is security issue. Check folder permissions and service account under which SQL server 2008 starts.

JsonPath jsonPathEvaluator = response.jsonPath();
return jsonPathEvaluator.get("user_id").toString();

Awk can fix up the output to give just what the questioner asked for. On my Solaris 10 system, find -ls prints size in KB as the second field, so:

% find . -name '*.ear' -ls | awk '{print $2, $11}'
5400 ./dir1/dir2/earFile2.ear
5400 ./dir1/dir2/earFile3.ear
5400 ./dir1/dir2/earFile1.ear

Otherwise, use -exec ls -lh and pick out the size field from the output. Again on Solaris 10:

% find . -name '*.ear' -exec ls -lh {} \; | awk '{print $5, $9}'
5.3M ./dir1/dir2/earFile2.ear
5.3M ./dir1/dir2/earFile3.ear
5.3M ./dir1/dir2/earFile1.ear

You can try doing:

String myResource = IOUtils.toString(this.getClass().getResourceAsStream("yourfile.xml")).replace("\n","");

Use the children function with the :first selector to get the single first child of element:

element.children(":first").toggleClass("redClass");

Aside from @JsonIgnore, there are a couple of other possibilities:

• Use JSON Views to filter out fields conditionally (by default, not used for deserialization; in 2.0 will be available but you can use different view on serialization, deserialization)
• @JsonIgnoreProperties on class may be useful

Note also that vertical-align:top; is often necessary for correct table cell appearance.

css table-cell, contents have unnecessary top margin

Use UNION:

SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks
UNION
SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks

Or UNION ALL if you want duplicates:

SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks
UNION ALL
SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks

SELECT id FROM `table` ORDER BY id DESC LIMIT 1

Although I doubt in its productiveness but it's 100% reliable

This is what I use to get the root view as found in the XML file assigned with setContentView:

final ViewGroup viewGroup = (ViewGroup) ((ViewGroup) this
            .findViewById(android.R.id.content)).getChildAt(0);

I would use:

CONVERT(char(10),GETDATE(),126)

This happens because your click handler fires before the value of the radio button changes. You need to listen to the change event instead:

<input 
  type="radio" 
  name="optionsRadios" 
  id="optionsRadios2" 
  value=""
  v-model="srStatus" 
  v-on:change="foo"> //here

Also, make sure you really want to call foo() on ready... seems like maybe you don't actually want to do that.

ready:function(){
    foo();
},

If your user has a local folder e.g. Linux, in your users home folder you could create a .my.cnf file and provide the credentials to access the server there. for example:-

[client]
host=localhost
user=yourusername
password=yourpassword or exclude to force entry
database=mygotodb

Mysql would then open this file for each user account read the credentials and open the selected database.

Not sure on Windows, I upgraded from Windows because I needed the whole house not just the windows (aka Linux) a while back.

Maybe I'm over simplifying here, and that may be the case, but this seems to work for me. Haven't ran into any problems with it yet...

CAST('1/1/' + CAST(YEAR(GETDATE()) AS VARCHAR(30)) AS DATETIME) + (DATEPART(wk, YOUR_DATE) * 7 - 7) as 'FirstDayOfWeek'
CAST('1/1/' + CAST(YEAR(GETDATE()) AS VARCHAR(30)) AS DATETIME) + (DATEPART(wk, YOUR_DATE) * 7) as 'LastDayOfWeek'

try this:

HTML:

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
  <div class="item">5</div>
</div>

CSS:

.container {
  width: 200px;
  height: 100px;
  display: flex;
  overflow-x: auto;
}

.item {
  width: 100px;
  flex-shrink: 0;
  height: 100px;
}

The white-space: nowrap; property dont let you wrap text. Just see here for an example: https://codepen.io/oezkany/pen/YoVgYK

You don't.

If you want to extend Person with Student, just do:

public class Student extends Person
{
}

And make sure, when you compile both classes, one can find the other one.

What IDE are you using?

Consider following code

<ul id="myTask">
  <li>Coding</li>
  <li>Answering</li>
  <li>Getting Paid</li>
</ul>

Now, here goes the difference

// Remove the myTask item when clicked.
$('#myTask').children().click(function () {
  $(this).remove()
});

Now, what if we add a myTask again?

$('#myTask').append('<li>Answer this question on SO</li>');

Clicking this myTask item will not remove it from the list, since it doesn't have any event handlers bound. If instead we'd used .on, the new item would work without any extra effort on our part. Here's how the .on version would look:

$('#myTask').on('click', 'li', function (event) {
  $(event.target).remove()
});

Summary:

The difference between .on() and .click() would be that .click() may not work when the DOM elements associated with the .click() event are added dynamically at a later point while .on() can be used in situations where the DOM elements associated with the .on() call may be generated dynamically at a later point.

You can do

[5, 10].min

or

[4, 7].max

They come from the Enumerable module, so anything that includes Enumerable will have those methods available.

v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each.

@nicholasklick mentions another option, Enumerable#minmax, but this time returning an array of [min, max].

[4, 5, 7, 10].minmax
=> [4, 10]

The exact solution is;

$("#dialogDiv").dialog({ other options...,
    open: function (type, data) {
        $(this).parent().appendTo("form");
    }
});

NULL isn't a keyword; it's a macro substitution for 0, and comes in stddef.h or cstddef, I believe. You haven't #included an appropriate header file, so g++ sees NULL as a regular variable name, and you haven't declared it.

Another possibility: When you created the user, you may have accidentally been useing a database other than admin, or other than the one you wanted. You need to set --authenticationDatabase to the database that the user was actually created under.

mongodb seems to put you in the test database by default when you open the shell, so you'd need to write --authenticationDatabase test rather than --authenticationDatabase admin if you accidentally were useing test when you ran db.createUser(...).

Assuming you have access to the machine that's running the mongodb instance, y could disable authorization in /etc/mongod.conf (comment out authorization which is nested under security), and then restart your server, and then run:

mongo
show users

And you might get something like this:

{
    "_id" : "test.myusername",
    "user" : "myusername",
    "db" : "test",
    "roles" : [
        {
            "role" : "dbOwner",
            "db" : "mydatabasename"
        }
    ],
    "mechanisms" : [
        "SCRAM-SHA-1",
        "SCRAM-SHA-256"
    ]
}

Notice that the db value equals test. That's because when I created the user, I didn't first run use admin or use desiredDatabaseName. So you can delete the user with db.dropUser("myusername") and then create another user under your desired database like so:

use desiredDatabaseName
db.createUser(...)

Hopefully that helps someone who was in my position as a noob with this stuff.

change the input boxes like

<input type="checkbox" name="c1" onclick="showMe('div1')">Show Hide Checkbox
<input type="checkbox" name="c1" onclick="showMe('div1')">Show Hide Checkbox
<input type="checkbox" name="c1" onclick="showMe('div1')">Show Hide Checkbox
<input type="checkbox" name="c1" onclick="showMe('div1')">Show Hide Checkbox

and js code as

function showMe (box) {

    var chboxs = document.getElementsByName("c1");
    var vis = "none";
    for(var i=0;i<chboxs.length;i++) { 
        if(chboxs[i].checked){
         vis = "block";
            break;
        }
    }
    document.getElementById(box).style.display = vis;


}

here is a demo fiddle

You can use time.time() or time.clock() before and after the block you want to time.

import time

t0 = time.time()
code_block
t1 = time.time()

total = t1-t0

This method is not as exact as timeit (it does not average several runs) but it is straightforward.

time.time() (in Windows and Linux) and time.clock() (in Linux) are not precise enough for fast functions (you get total = 0). In this case or if you want to average the time elapsed by several runs, you have to manually call the function multiple times (As I think you already do in you example code and timeit does automatically when you set its number argument)

import time

def myfast():
   code

n = 10000
t0 = time.time()
for i in range(n): myfast()
t1 = time.time()

total_n = t1-t0

In Windows, as Corey stated in the comment, time.clock() has much higher precision (microsecond instead of second) and is preferred over time.time().

If using a where clause be sure to include .First() if you do not want a IQueryable object.

Starting from Laravel 5.1.26, tagged on 2015-12-02, a useCurrent() modifier has been added:

Schema::table('users', function ($table) {
    $table->timestamp('created')->useCurrent();
});

PR 10962 (followed by commit 15c487fe) leaded to this addition.

You may also want to read issues 3602 and 11518 which are of interest.

Basically, MySQL 5.7 (with default config) requires you to define either a default value or nullable for time fields.

I would implement a null safe comparator. There may be an implementation out there, but this is so straightforward to implement that I've always rolled my own.

Note: Your comparator above, if both names are null, won't even compare the value fields. I don't think this is what you want.

I would implement this with something like the following:

// primarily by name, secondarily by value; null-safe; case-insensitive
public int compareTo(final Metadata other) {

    if (other == null) {
        throw new NullPointerException();
    }

    int result = nullSafeStringComparator(this.name, other.name);
    if (result != 0) {
        return result;
    }

    return nullSafeStringComparator(this.value, other.value);
}

public static int nullSafeStringComparator(final String one, final String two) {
    if (one == null ^ two == null) {
        return (one == null) ? -1 : 1;
    }

    if (one == null && two == null) {
        return 0;
    }

    return one.compareToIgnoreCase(two);
}

EDIT: Fixed typos in code sample. That's what I get for not testing it first!

EDIT: Promoted nullSafeStringComparator to static.

For validation I ran the benchmark code provided by @Cron. There is one major difference (in addition to running faster on the newer i7 processor): the by_index now performs nearly as well as the list_:

it's worth noting that the Win32_Product WMI class represents products as they are installed by Windows Installer. not every application use windows installer

For 64 bit you also need to traverse "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" and since not every software has a 64 bit version the total applications installed are a union of keys on both locations that have "UninstallString" Value with them.

but the best options remains the same .traverse registry keys is a better approach since every application have an entry in registry[including the ones in Windows Installer].however the registry method is insecure as if anyone removes the corresponding key then you will not know the Application entry.On the contrary Altering the HKEY_Classes_ROOT\Installers is more tricky as it is linked with licensing issues such as Microsoft office or other products. for more robust solution you can always combine registry alternative with the WMI.

When using SASS I use the following 2 @media queries to target IE 6-10 & EDGE.

@media screen\9
    @import ie_styles
@media screen\0
    @import ie_styles

http://keithclark.co.uk/articles/moving-ie-specific-css-into-media-blocks/

Edit

I also target later versions of EDGE using @support queries (add as many as you need)

@supports (-ms-ime-align:auto)
    @import ie_styles
@supports (-ms-accelerator:auto)
    @import ie_styles

I've used the following solution in my project. I think it is better than using mutable objects or integer ranges.

I fixed this using Anaconda by going to Environments > base(root), searching for numpy in the installed modules and clicking the tickbox alongside it and choosing > Mark for specific version installation > 1.14.0 (as suggested by another user on this thread). Then clicking Apply. Once it downgraded numpy I stopped getting errors when running py files on the command line.

Throughout this saga, I was still able to use https://pypi.org/project/auto-py-to-exe/ even when I was getting the numpy errors on the command line, but it was a hassle to create an exe every time I wanted to test a change. It's all sorted now. I guess there was a problem with numpy 1.16.4.

Anyway, I hope this helps someone who's using Anaconda as well.

FileReader uses Java's platform default encoding, which depends on the system settings of the computer it's running on and is generally the most popular encoding among users in that locale.

If this "best guess" is not correct then you have to specify the encoding explicitly. Unfortunately, FileReader does not allow this (major oversight in the API). Instead, you have to use new InputStreamReader(new FileInputStream(filePath), encoding) and ideally get the encoding from metadata about the file.

It truly solved my problem using eval function.

single_quoted_dict_in_string = "{'key':'value', 'key2': 'value2'}"
desired_double_quoted_dict = eval(single_quoted_dict_in_string)
# Go ahead, now you can convert it into json easily
print(desired_double_quoted_dict)

Even better: use the inspect.isclass function.

>>> import inspect
>>> class X(object):
...     pass
... 
>>> inspect.isclass(X)
True

>>> x = X()
>>> isinstance(x, X)
True
>>> y = 25
>>> isinstance(y, X)
False

The mysql_upgrade worked for me as well:

# mysql_upgrade -u root -p --force
# systemctl restart mysqld

Regards, MSz.

The warning:

deprecated conversion from string constant to 'char*'

is given because you are doing somewhere (not in the code you posted) something like:

void foo(char* str);
foo("hello");

The problem is that you are trying to convert a string literal (with type const char[]) to char*.

You can convert a const char[] to const char* because the array decays to the pointer, but what you are doing is making a mutable a constant.

This conversion is probably allowed for C compatibility and just gives you the warning mentioned.

Just paste this into your line of codes:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

If it's Windows, all you need to do is delete the root of that project within the file explorer. Just right click on the name of the app in Android Studio, and then "show in file explorer". Then just delete the project folder all in all.

Another alternative is numpy.broadcast_to(val,n) which returns in constant time regardless of the size and is also the most memory efficient (it returns a view of the repeated element). The caveat is that the returned value is read-only.

Below is a comparison of the performances of all the other methods that have been proposed using the same benchmark as in Nico Schlömer's answer.

As of Pandas 0.18 one way to do this is to use the sort_index method of the grouped data.

Here's an example:

np.random.seed(1)
n=10
df = pd.DataFrame({'mygroups' : np.random.choice(['dogs','cats','cows','chickens'], size=n), 
                   'data' : np.random.randint(1000, size=n)})

grouped = df.groupby('mygroups', sort=False).sum()
grouped.sort_index(ascending=False)
print grouped

data
mygroups      
dogs      1831
chickens  1446
cats       933

As you can see, the groupby column is sorted descending now, indstead of the default which is ascending.

You can also delete cookies without using jquery.cookie plugin:

document.cookie = 'NAMEOFYOURCOOKIE' + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';

var redBox = $(".post");

var greenBox = $(".post1");

var offset = redBox.offset();

$(".post1").css({'left': +offset.left});
$(".post1").html("Left :" +offset.left);

Note that as others have pointed out mysql_real_escape_string() will solve the problem (as will addslashes), however you should always use mysql_real_escape_string() for security reasons - consider:

SELECT * FROM valid_users WHERE username='$user' AND password='$password'

What if the browser sends

user="admin' OR (user=''"
password="') AND ''='"

The query becomes:

SELECT * FROM valid_users 
WHERE username='admin' OR (user='' AND password='') AND ''=''

i.e. the security checks are completely bypassed.

C.

Add a label control to your Repeater's ItemTemplate. Handle OnItemCreated event.

ASPX

<asp:Repeater ID="rptr" runat="server" OnItemCreated="RepeaterItemCreated">
    <ItemTemplate>
        <div id="width:50%;height:30px;background:#0f0a0f;">
            <asp:Label ID="lblSr" runat="server" 
               style="width:30%;float:left;text-align:right;text-indent:-2px;" />
            <span 
               style="width:65%;float:right;text-align:left;text-indent:-2px;" >
            <%# Eval("Item") %>
            </span>
        </div>
    </ItemTemplate>
</asp:Repeater>

Code Behind:

    protected void RepeaterItemCreated(object sender, RepeaterItemEventArgs e)
    {
        Label l = e.Item.FindControl("lblSr") as Label;
        if (l != null)
            l.Text = e.Item.ItemIndex + 1+"";
    }

this is for classes

$('.nameofdiv').val('we are developers');

for ids

$('#nameofdiv').val('we are developers');

now if u have an iput in a form u can use

$("#form li.name input.name_val").val('we are awsome developers');

You have to give a name attribute on your <select /> element, and then use it from the $_POST or $_GET (depending on how you transmit data) arrays in PHP. Be sure to sanitize user input, though.

If you set the AllowsTransparency property on the Window (even without setting any transparency values) the border disappears and you can only resize via the grip.

    WindowStyle="None"
    AllowsTransparency="True"
    ResizeMode="CanResizeWithGrip">

Result looks like:

Download commons-net binary from here. Extract the files and reference the commons-net-x.x.jar file.

Delete your .git folder, and reinitialize the git with git init, in my case that's work , because git add command staging the folder and the files in .git folder, if you close CLI after the commit , there will be double folder in staging area that make git system throw this issue.

It looks like you want:

public static string GetRandomBits()

Without static, you would need an object before you can call the GetRandomBits() method. However, since the implementation of GetRandomBits() does not depend on the state of any Program object, it's best to declare it static.

If it's an object method, you need to pass the object to CallObjectMethod:

jobject result = env->CallObjectMethod(obj, messageMe, jstr);

What you were doing was the equivalent of jstr.messageMe().

Since your is a void method, you should call:

env->CallVoidMethod(obj, messageMe, jstr);

If you want to return a result, you need to change your JNI signature (the ()V means a method of void return type) and also the return type in your Java code.

You can use MPAndroidChart.

It's native, free, easy to use, fast and reliable.

Core features, benefits:

• LineChart, BarChart (vertical, horizontal, stacked, grouped), PieChart, ScatterChart, CandleStickChart (for financial data), RadarChart (spider web chart), BubbleChart
• Combined Charts (e.g. lines and bars in one)
• Scaling on both axes (with touch-gesture, axes separately or pinch-zoom)
• Dragging / Panning (with touch-gesture)
• Separate (dual) y-axes
• Highlighting values (with customizeable popup-views)
• Save chart to SD-Card (as image)
• Predefined color templates
• Legends (generated automatically, customizeable)
• Customizeable Axes (both x- and y-axis)
• Animations (build up animations, on both x- and y-axis)
• Limit lines (providing additional information, maximums, ...)
• Listeners for touch, gesture & selection callbacks
• Fully customizeable (paints, typefaces, legends, colors, background, dashed lines, ...)
• Realm.io mobile database support via MPAndroidChart-Realm library
• Smooth rendering for up to 10.000 data points in Line- and BarChart
• Lightweight (method count ~1.4K)
• Available as .jar file (only 500kb in size)
• Available as gradle dependency and via maven
• Good documentation
• Example Project (code for demo-application)
• Google-PlayStore Demo Application
• Widely used, great support on both GitHub and stackoverflow - mpandroidchart
• Also available for iOS: Charts (API works the same way)
• Also available for Xamarin: MPAndroidChart.Xamarin

Drawbacks:

• No official support for dynamic & realtime data, limited performance in that area

Disclaimer: I am the developer of this library.

It's because of the way NOT IN works.

To avoid these headaches (and for a faster query in many cases), I always prefer NOT EXISTS:

SELECT  *  
FROM Table1 t1 
WHERE NOT EXISTS (
    SELECT * 
    FROM Table2 t2 
    WHERE t1.MAKE = t2.MAKE
    AND   t1.MODEL = t2.MODEL
    AND   t1.[Serial Number] = t2.[serial number]);

The global scope in React Native is variable global. Such as global.foo = foo, then you can use global.foo anywhere.

But do not abuse it! In my opinion, global scope may used to store the global config or something like that. Share variables between different views, as your description, you can choose many other solutions(use redux,flux or store them in a higher component), global scope is not a good choice.

A good practice to define global variable is to use a js file. For example global.js

global.foo = foo;
global.bar = bar;

Then, to make sure it is executed when project initialized. For example, import the file in index.js:

import './global.js'
// other code

Now, you can use the global variable anywhere, and don't need to import global.js in each file. Try not to modify them!

git cherry-pick : Apply the changes introduced by some existing commits

Assume we have branch A with (X, Y, Z) commits. We need to add these commits to branch B. We are going to use the cherry-pick operations.

When we use cherry-pick, we should add commits on branch B in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout B
git cherry-pick SHA-COMMIT-X
git cherry-pick SHA-COMMIT-Y
git cherry-pick SHA-COMMIT-Z

Example of workflow :

We can use cherry-pick with options

-e or --edit : With this option, git cherry-pick will let you edit the commit message prior to committing.

-n or --no-commit : Usually the command automatically creates a sequence of commits. This flag applies the changes necessary to cherry-pick each named commit to your working tree and the index, without making any commit. In addition, when this option is used, your index does not have to match the HEAD commit. The cherry-pick is done against the beginning state of your index.

Here an interesting article concerning cherry-pick.

Or you could simply use

View.isShown()

Well, the documentation does actually state that

CodeIgniter supports "flashdata", or session data that will only be available for the next server request, and are then automatically cleared.

as the very first thing, which obviusly means that you need to do a new server request. A redirect, a refresh, a link or some other mean to send the user to the next request.

Why use flashdata if you are using it in the same request, anyway? You'd might as well not use flashdata or use a regular session.

You need to await the GetAsync method. It will then throw a TaskCanceledException if it has timed out. Additionally, GetStringAsync and GetStreamAsync internally handle timeout, so they will NEVER throw.

string baseAddress = "http://localhost:8080/";
var client = new HttpClient() 
{ 
    BaseAddress = new Uri(baseAddress), 
    Timeout = TimeSpan.FromMilliseconds(1) 
};
try
{
    var s = await client.GetAsync();
}
catch(Exception e)
{
    Console.WriteLine(e.Message);
    Console.WriteLine(e.InnerException.Message);
}

I think your problem is that

int selection = scanner.nextInt();

reads just the number, not the end of line or anything after the number. When you declare

String sentence = scanner.nextLine();

This reads the remainder of the line with the number on it (with nothing after the number I suspect)

Try placing a scanner.nextLine(); after each nextInt() if you intend to ignore the rest of the line.

A String is a type of Object. So any method that accepts Object as parameter will surely accept String also. Please provide more of your code if you still do not find a solution.

In Java version prior to 1.7 you cannot cast object to primitive type

double d = (double) obj;

You can cast an Object to a Double just fine

Double d = (Double) obj;

Beware, it can throw a ClassCastException if your object isn't a Double

Update! New & improved! Find plugin @ GitHub!

On another note, while that method is simple, I've created a jQuery plug (found at this jsFiddle, just copy and past code between comment lines) that makes changing the cursor on any element as simple as $("element").cursor("pointer").

But that's not all! Act now and you'll get the hand functions position & ishover for no extra charge! That's right, 2 very handy cursor functions ... FREE!

They work as simple as seen in the demo:

$("h3").cursor("isHover"); // if hovering over an h3 element, will return true, 
    // else false
// also handy as
$("h2, h3").cursor("isHover"); // unless your h3 is inside an h2, this will be 
    // false as it checks to see if cursor is hovered over both elements, not just the last!
//  And to make this deal even sweeter - use the following to get a jQuery object
//       of ALL elements the cursor is currently hovered over on demand!
$.cursor("isHover");

Also:

$.cursor("position"); // will return the current cursor position as { x: i, y: i }
    // at anytime you call it!

Supplies are limited, so Act Now!

The getContentResolver()method is also used when you query a Contact, using a Cursor object. I have used getContentResolver() to query the Android phone Contacts app, looking for contact info from a person's phone number, to include in my app. The different elements in a query (as shown below) represent what kind of contact details you want, and if they should be ordered, etc. Here is another example.

From the Content Provider Basics page from Android docs.

// Queries the user dictionary and returns results
mCursor = getContentResolver().query(
    UserDictionary.Words.CONTENT_URI,   // The content URI of the words table
    mProjection,                        // The columns to return for each row
    mSelectionClause                    // Selection criteria
    mSelectionArgs,                     // Selection criteria
    mSortOrder);                        // The sort order for the returned rows

/*$mpdf = new mPDF('',    // mode - default ''
 '',    // format - A4, for example, default ''
 0,     // font size - default 0
 '',    // default font family
 15,    // margin_left
 15,    // margin right
 16,     // margin top
 16,    // margin bottom
 9,     // margin header
 9,     // margin footer
 'L');  // L - landscape, P - portrait*/

    NSDate *timeLater = [NSDate dateWithTimeIntervalSinceNow:60*90];

    NSTimeInterval duration = [timeLater  timeIntervalSinceNow];

    NSInteger hours = floor(duration/(60*60));
    NSInteger minutes = floor((duration/60) - hours * 60);
    NSInteger seconds = floor(duration - (minutes * 60) - (hours * 60 * 60));

    NSLog(@"timeLater: %@", [dateFormatter stringFromDate:timeLater]);

    NSLog(@"time left: %d hours %d minutes  %d seconds", hours,minutes,seconds);

Outputs:

timeLater: 22:27
timeLeft: 1 hours 29 minutes  59 seconds

You can also check out github.com/wushilin/stream

It is a lazy stream like concept of java.util.stream.

// It doesn't really allocate the 10 elements.
stream1 := stream.Range(0, 10)

// Print each element.
stream1.Each(print)

// Add 3 to each element, but it is a lazy add.
// You only add when consume the stream
stream2 := stream1.Map(func(i int) int {
    return i + 3
})

// Well, this consumes the stream => return sum of stream2.
stream2.Reduce(func(i, j int) int {
    return i + j
})

// Create stream with 5 elements
stream3 := stream.Of(1, 2, 3, 4, 5)

// Create stream from array
stream4 := stream.FromArray(arrayInput)

// Filter stream3, keep only elements that is bigger than 2,
// and return the Sum, which is 12
stream3.Filter(func(i int) bool {
    return i > 2
}).Sum()

Hope this helps

If you are not allowed to use C++'s string class (which is terrible teaching C++ imho), a raw, safe array version would look something like this.

#include <cstring>
#include <iostream>

int main()
{
    char array1[] ="The dog jumps ";
    char array2[] = "over the log";
    char * newArray = new char[std::strlen(array1)+std::strlen(array2)+1];
    std::strcpy(newArray,array1);
    std::strcat(newArray,array2);
    std::cout << newArray << std::endl;
    delete [] newArray;
    return 0;
}

This assures you have enough space in the array you're doing the concatenation to, without assuming some predefined MAX_SIZE. The only requirement is that your strings are null-terminated, which is usually the case unless you're doing some weird fixed-size string hacking.

Edit, a safe version with the "enough buffer space" assumption:

#include <cstring>
#include <iostream>

int main()
{
    const unsigned BUFFER_SIZE = 50;
    char array1[BUFFER_SIZE];
    std::strncpy(array1, "The dog jumps ", BUFFER_SIZE-1); //-1 for null-termination
    char array2[] = "over the log";
    std::strncat(array1,array2,BUFFER_SIZE-strlen(array1)-1); //-1 for null-termination
    std::cout << array1 << std::endl;
    return 0;
}

Otherwise we may change the default property configurator name, setting the property spring.config.name=test and then having class-path resource src/test/test.properties our native instance of org.springframework.boot.SpringApplication will be auto-configured from this separated test.properties, ignoring application properties;

Benefit: auto-configuration of tests;

Drawback: exposing "spring.config.name" property at C.I. layer

ref: http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

spring.config.name=application # Config file name

As previously mentioned, the bundler version may be too high for your version of rails.

I ran into the same problem using Rails 3.0.1 which requires Bundler v1.0.0 - v1.0.22

Check your bundler version using: gem list bundler

If your bundler version is not within the appropriate range, I found this solution to work: rvm @global do gem uninstall bundler

Note: rvm is required for this solution... another case for why you should be using rvm in the first place.

I think the problem is that you load isfar data.frame but you overwrite it by value returned by load.

Try either:

load("C:/Users/isfar.RData") 
head(isfar)

Or more general way

load("C:/Users/isfar.RData", ex <- new.env())
ls.str(ex) 

After a few hours of messing around I eventually got something that works, partially answered in a similar issue here: How do I include a JavaScript file in another JavaScript file?

BUT there was an import that was screwing the rest of it up:

Use require in .vue files

<script>
  var mylib = require('./mylib');
  export default {
  ....

Exports in mylib

 exports.myfunc = () => {....}

Avoid import

The actual issue in my case (which I didn't think was relevant!) was that mylib.js was itself using other dependencies. The resulting error seems to have nothing to do with this, and there was no transpiling error from webpack but anyway I had:

import models from './model/models'
import axios from 'axios'

This works so long as I'm not using mylib in a .vue component. However as soon as I use mylib there, the error described in this issue arises.

I changed to:

let models = require('./model/models');
let axios = require('axios');

And all works as expected.

You can use .filter() method of the Array object:

var filtered = workItems.filter(function(element) {
   // Create an array using `.split()` method
   var cats = element.category.split(' ');

   // Filter the returned array based on specified filters
   // If the length of the returned filtered array is equal to
   // length of the filters array the element should be returned  
   return cats.filter(function(cat) {
       return filtersArray.indexOf(cat) > -1;
   }).length === filtersArray.length;
});

http://jsfiddle.net/6RBnB/

Some old browsers like IE8 doesn't support .filter() method of the Array object, if you are using jQuery you can use .filter() method of jQuery object.

jQuery version:

var filtered = $(workItems).filter(function(i, element) {
   var cats = element.category.split(' ');

    return $(cats).filter(function(_, cat) {
       return $.inArray(cat, filtersArray) > -1;
    }).length === filtersArray.length;
});

it is because of using web address, You can not use http to write data. don't use : http:// or https:// in your location for upload files or save data or somting like that. instead of of using $_SERVER["HTTP_REFERER"] use $_SERVER["DOCUMENT_ROOT"]. for example :

wrong :

move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["HTTP_REFERER"].'/uploads/images/1.jpg')

correct:

move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["DOCUMENT_ROOT"].'/uploads/images/1.jpg')

$rootScope.$on( "$routeChangeStart", function(event, next, current) {
  //..do something
  //event.stopPropagation();  //if you don't want event to bubble up 
});

Use this class (https://github.com/BlakeGardner/php-mac-address)

This is a PHP class for MAC address manipulation on top of Unix, Linux and Mac OS X operating systems. it was primarily written to help with spoofing for wireless security audits.

Building off of Fabio's answer, I created two functions that will probably be useful for anyone stumbling upon this question. With these two functions, you can call insertParam() with a key and value as an argument. It will either add the URL parameter or, if a query param already exists with the same key, it will change that parameter to the new value:

//function to remove query params from a URL
function removeURLParameter(url, parameter) {
    //better to use l.search if you have a location/link object
    var urlparts= url.split('?');   
    if (urlparts.length>=2) {

        var prefix= encodeURIComponent(parameter)+'=';
        var pars= urlparts[1].split(/[&;]/g);

Step 1. Follow answer from user4847410 above. Next time you connect your phone it will come up with an authorisation message and you're in.

Step 2. I also swapped my cable.

Step 3. Check USB port as if you install on one particular port then another port may not be ok for you.

You can use the rename.vars in the gdata package.

library(gdata)
df <- rename.vars(df, from = "oldname", to = "newname")

This is particularly useful where you have more than one variable name to change or you want to append or pre-pend some text to the variable names, then you can do something like:

df <- rename.vars(df, from = c("old1", "old2", "old3", 
         to = c("new1", "new2", "new3"))

For an example of appending text to a subset of variables names see: https://stackoverflow.com/a/28870000/180892

Here's a Boolean thing:

if (not suffix == "flac" )  or (not suffix == "cue" ):   # WRONG! FAILS
    print  filename + ' is not a flac or cue file'

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

None except @Akira Sendoh has answered how to actually get ALL docs. But even that solution crashes my ES 6.3 service without logs. The only thing that worked for me using the low-level elasticsearch-py library was through scan helper that uses scroll() api:

from elasticsearch.helpers import scan

doc_generator = scan(
    es_obj,
    query={"query": {"match_all": {}}},
    index="my-index",
)

# use the generator to iterate, dont try to make a list or you will get out of RAM
for doc in doc_generator:
    # use it somehow

However, the cleaner way nowadays seems to be through elasticsearch-dsl library, that offers more abstract, cleaner calls, e.g: http://elasticsearch-dsl.readthedocs.io/en/latest/search_dsl.html#hits

I had similar error: "Expecting value: line 1 column 1 (char 0)"

It helped for me to add "myfile.seek(0)", move the pointer to the 0 character

with open(storage_path, 'r') as myfile:
if len(myfile.readlines()) != 0:
    myfile.seek(0)
    Bank_0 = json.load(myfile)

Have a look at the handleEvent method
https://developer.mozilla.org/en-US/docs/Web/API/EventListener

"Raw" Javascript:

function MyObj() {
   this.abc = "ABC";
}
MyObj.prototype.handleEvent = function(e) {
   console.log("caught event: "+e.type);
   console.log(this.abc);
}

var myObj = new MyObj();

document.querySelector("#myElement").addEventListener('click', myObj);

Now click on your element (with id "myElement") and it should print the following in the console:

caught event: click
ABC

This allows you to have an object method as event handler, and have access to all the object properties in that method.

You can't just pass a method of an object to addEventListener directly (like that: element.addEventListener('click',myObj.myMethod);) and expect myMethod to act as if I was normally called on the object. I am guessing that any function passed to addEventListener is somehow copied instead of being referenced. For example, if you pass an event listener function reference to addEventListener (in the form of a variable) then unset this reference, the event listener is still executed when events are caught.

Another (less elegant) workaround to pass a method as event listener and stil this and still have access to object properties within the event listener would be something like that:

// see above for definition of MyObj

var myObj = new MyObj();

document.querySelector("#myElement").addEventListener('click', myObj.handleEvent.bind(myObj));

Just be careful. You will get this message if you try to enter a command that doesn't exist like this

/usr/bin/java -v

One alternative instead of using hard-coded values could be using range mappings on the the switch statement instead:

private static final int RANGE_5_100 = 1;
private static final int RANGE_101_1000 = 2;
private static final int RANGE_1001_10000 = 3;

public boolean handleRanges(int n) {
    int rangeCode = getRangeCode(n);
    switch (rangeCode) {
        case RANGE_5_100: // doSomething();
        case RANGE_101_1000: // doSomething();
        case RANGE_1001_10000: // doSomething();
        default: // invalid range
    }
}

private int getRangeCode(int n) {
    if (n >= 5 && n <= 100) {
        return RANGE_5_100;
    } else if (n >= 101 && n <= 1000) {
        return RANGE_101_1000;
    } else if (n >= 1001 && n <= 10000) {
        return RANGE_1001_10000;
    }

    return -1;
}

Difference between Read(),Readline() and ReadKey() in C#

Read()-Accept the string value and return the string value. Readline() -Accept the string and return Integer ReadKey() -Accept the character and return Character

Summary:

1.The above mentioned three methods are mainly used in Console application and these are used for return the different values . 2.If we use Read line or Read() we need press Enter button to come back to code. 3.If we using Read key() we can press any key to come back code in application

I was facing the same problem and the second method proposed in the accepted answer, as noted in the comments, can be problematic when dealing with foreign keys.

My workaround is to export the database to a sql file making sure that the INSERT statements include column names. I do it using DB Browser for SQLite which has an handy feature for that. After that you just have to edit the create table statement and insert the new column where you want it and recreate the db.

In *nix like systems is just something along the lines of

cat db.sql | sqlite3 database.db

I don't know how feasible this is with very big databases, but it worked in my case.

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

I think you will find more information in this link:

http://codeidol.com/community/dotnet/controlling-case-sensitivity-when-comparing-two-st/8873/

Use the Compare static method on the String class to compare the two strings. Whether the comparison is case-insensitive is determined by the third parameter of one of its overloads. For example:

string lowerCase = "abc";
string upperCase = "AbC";
int caseInsensitiveResult = string.Compare(lowerCase, upperCase,
  StringComparison.CurrentCultureIgnoreCase);
int caseSensitiveResult = string.Compare(lowerCase,
  StringComparison.CurrentCulture);

The caseSensitiveResult value is -1 (indicating that lowerCase is "less than" upperCase) and the caseInsensitiveResult is zero (indicating that lowerCase "equals" upperCase).

I was able to use the answer outlined here: Export to CSV using jQuery and html and added in a modification to make it work in IE and another modification mentioned in the comments to grab the thead from the table.

function exportTableToCSV($table, filename) {

    var $rows = $table.find('tr:has(td),tr:has(th)'),

        // Temporary delimiter characters unlikely to be typed by keyboard
        // This is to avoid accidentally splitting the actual contents
        tmpColDelim = String.fromCharCode(11), // vertical tab character
        tmpRowDelim = String.fromCharCode(0), // null character

        // actual delimiter characters for CSV format
        colDelim = '","',
        rowDelim = '"\r\n"',

        // Grab text from table into CSV formatted string
        csv = '"' + $rows.map(function (i, row) {
            var $row = $(row), $cols = $row.find('td,th');

            return $cols.map(function (j, col) {
                var $col = $(col), text = $col.text();

                return text.replace(/"/g, '""'); // escape double quotes

            }).get().join(tmpColDelim);

        }).get().join(tmpRowDelim)
            .split(tmpRowDelim).join(rowDelim)
            .split(tmpColDelim).join(colDelim) + '"',



        // Data URI
        csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

        console.log(csv);

        if (window.navigator.msSaveBlob) { // IE 10+
            //alert('IE' + csv);
            window.navigator.msSaveOrOpenBlob(new Blob([csv], {type: "text/plain;charset=utf-8;"}), "csvname.csv")
        } 
        else {
            $(this).attr({ 'download': filename, 'href': csvData, 'target': '_blank' }); 
        }
}

// This must be a hyperlink
$("#xx").on('click', function (event) {

    exportTableToCSV.apply(this, [$('#projectSpreadsheet'), 'export.csv']);

    // IF CSV, don't do event.preventDefault() or return false
    // We actually need this to be a typical hyperlink
});

There is an easier way to get the exact version .NET version installed on your machine from a cmd prompt. Just follow the following instructions;

Open the command prompt (i.e Windows + R ? type “cmd”) and type the following command, all on one line: %windir%\Microsoft.NET\FrameWork, and then navigating to the directory with the latest version number.

Refer to http://dotnettec.com/check-dot-net-framework-version/

I was fighting for about 2-3 hours to codesign a project with Parse API. It turned out that the embedded frameworks caused the problem. Make sure you set "Code sign on copy" (see picture). If does not work delete the Parse and Bolts frameworks from the list and remove them from your project then add them again.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

DECLARE @FirstDate DATE = '2018-01-01'
DECLARE @LastDate Date = '2018-12-31'
DECLARE @tbl TABLE(ID INT IDENTITY(1,1) PRIMARY KEY,CurrDate date)
INSERT @tbl VALUES( @FirstDate)
WHILE @FirstDate < @LastDate
BEGIN
SET @FirstDate = DATEADD( day,1, @FirstDate)
INSERT @tbl VALUES( @FirstDate)
END
INSERT @tbl VALUES( @LastDate) 

SELECT * FROM @tbl

The imshow() function with parameters interpolation='nearest' and cmap='hot' should do what you want.

import matplotlib.pyplot as plt
import numpy as np

a = np.random.random((16, 16))
plt.imshow(a, cmap='hot', interpolation='nearest')
plt.show()

Very old question, but for the newcomers: maybe the PowerShell version (similar but not equivalent) that the question is looking for, is to use -and as follows:

I got this error when I dynamically read data from a WebRequest and never closed the Response.

    protected System.IO.Stream GetStream(string url)
    {
        try
        {
            System.IO.Stream stream = null;
            var request = System.Net.WebRequest.Create(url);
            var response = request.GetResponse();

            if (response != null) {
                stream = response.GetResponseStream();

                // I never closed the response thus resulting in the error
                response.Close(); 
            }
            response = null;
            request = null;

            return stream;
        }
        catch (Exception) { }
        return null;
    }

In short: no. The first problem is access to the filesystem, which in most browsers is set to no by default due to security reasons. Modern browsers sometimes support minimalistic storage in the form of a database, or you can ask the user to enable file access.

If you have access to the filesystem then saving as HTML is not that hard (see the file object in the JS documentation) - but PDF is not so easy. PDF is a quite advanced file-format that really is ill suited for Javascript. It requires you to write information in datatypes not directly supported by Javascript, such as words and quads. You also need to pre-define a dictionary lookup system that must be saved to the file. Im sure someone could make it work, but the effort and time involved would be better spent learning C++ or Delphi.

HTML export however should be possible if the user gives you non restricted access

if it is a new repo you've cloned, it may still be empty, in which case:

git push -u origin master

should likely sort it out.

(did in my case. not sure this is the same issue, thought i should post this just incase. might help others.)

xmlstarlet is a command-line tool which will do this and more:

$ xmlstarlet val --help
XMLStarlet Toolkit: Validate XML document(s)
Usage: xmlstarlet val <options> [ <xml-file-or-uri> ... ]
where <options>
  -w or --well-formed        - validate well-formedness only (default)
  -d or --dtd <dtd-file>     - validate against DTD
  -s or --xsd <xsd-file>     - validate against XSD schema
  -E or --embed              - validate using embedded DTD
  -r or --relaxng <rng-file> - validate against Relax-NG schema
  -e or --err                - print verbose error messages on stderr
  -b or --list-bad           - list only files which do not validate
  -g or --list-good          - list only files which validate
  -q or --quiet              - do not list files (return result code only)

NOTE: XML Schemas are not fully supported yet due to its incomplete
      support in libxml2 (see http://xmlsoft.org)

XMLStarlet is a command line toolkit to query/edit/check/transform
XML documents (for more information see http://xmlstar.sourceforge.net/)

Usage in your case would be along the lines of:

xmlstarlet val --xsd your_schema.xsd your_file.xml

if you're looking for a simple column hide you can use the :nth-child selector as well.

#tableid tr td:nth-child(3),
#tableid tr th:nth-child(3) {
    display: none;
}

I use this with the @media tag sometimes to condense wider tables when the screen is too narrow.

I had a similar error which caused json_encode to return a null field whenever there was a hi-ascii character such as a curly apostrophe in a string, due to the wrong character set being returned in the query.

The solution was to make sure it comes as utf8 by adding:

mysql_set_charset('utf8');

after the mysql connect statement.

$('body').bind('beforeunload',function(){
   //do something
});

But this wont save any info for later, unless you were planning on saving that in a cookie somewhere (or local storage) and the unload event does not always fire in all browsers.

Example: http://jsfiddle.net/maniator/qpK7Y/

Code:

$(window).bind('beforeunload',function(){

     //save info somewhere

    return 'are you sure you want to leave?';

});

You are using a very old version of curl. My guess is that you run into the bug described 6 years ago. Fix is to update your curl.

If you have used:

from datetime import datetime

Then simply write the code as:

date = datetime(int(year), int(month), 1)

But if you have used:

import datetime

then only you can write:

date = datetime.datetime(int(2005), int(5), 1)

#include <stdio.h>
#include <string.h>

int main ()
{
        char someString[]="abcdedgh";
        char otherString[]="00000";
        memcpy (otherString, someString, 5);
        printf ("someString: %s\notherString: %s\n", someString, otherString);
        return 0;
}

You will not need stdio.h if you don't use the printf statement and putting constants in all but the smallest programs is bad form and should be avoided.

You can also use as Vector instead, as vectors are thread safe and arraylist are not. Though vectors are old but they can solve your purpose easily.

But you can make your Arraylist synchronized like code given this:

Collections.synchronizedList(new ArrayList(numberOfRaceCars())); 

I had same problem. In VB.Net it works easy that way:

VB XAML:

<TextBox x:Name="txtFilterFrequency" />

Codehind:

Private Sub txtFilterText_GotFocus(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles txtFilterText.GotFocus
    Me.Dispatcher.BeginInvoke(Sub()
                                  txtFilterText.SelectAll()
                              End Sub, DispatcherPriority.ApplicationIdle, Nothing)
End Sub

C# (thanks to ViRuSTriNiTy)

private delegate void TextBoxSelectAllDelegate(object sender);

private void TextBoxSelectAll(object sender)
{
    (sender as System.Windows.Controls.TextBox).SelectAll();
}

private void MyTextBox_GotFocus(object sender, System.Windows.RoutedEventArgs e)
{
    TextBoxSelectAllDelegate d = TextBoxSelectAll;

    this.Dispatcher.BeginInvoke(d,
        System.Windows.Threading.DispatcherPriority.ApplicationIdle, sender);
}

For ASPNET MVC, we did the following:

1. By default, set SessionStateBehavior.ReadOnly on all controller's action by overriding DefaultControllerFactory
2. On controller actions that need writing to session state, mark with attribute to set it to SessionStateBehavior.Required

Create custom ControllerFactory and override GetControllerSessionBehavior.

    protected override SessionStateBehavior GetControllerSessionBehavior(RequestContext requestContext, Type controllerType)
    {
        var DefaultSessionStateBehaviour = SessionStateBehaviour.ReadOnly;

        if (controllerType == null)
            return DefaultSessionStateBehaviour;

        var isRequireSessionWrite =

        if (isRequireSessionWrite)
            return SessionStateBehavior.Required;

        var actionName = requestContext.RouteData.Values["action"].ToString();
        MethodInfo actionMethodInfo;

        try
        {
            actionMethodInfo = controllerType.GetMethod(actionName, BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance);
        }
        catch (AmbiguousMatchException)
        {
            var httpRequestTypeAttr = GetHttpRequestTypeAttr(requestContext.HttpContext.Request.HttpMethod);

            actionMethodInfo =
                controllerType.GetMethods().FirstOrDefault(
                    mi => mi.Name.Equals(actionName, StringComparison.CurrentCultureIgnoreCase) && mi.GetCustomAttributes(httpRequestTypeAttr, false).Length > 0);
        }

        if (actionMethodInfo == null)
            return DefaultSessionStateBehaviour;

        isRequireSessionWrite = actionMethodInfo.GetCustomAttributes<AcquireSessionLock>(inherit: false).FirstOrDefault() != null;

         return isRequireSessionWrite ? SessionStateBehavior.Required : DefaultSessionStateBehaviour;
    }

                return typeof(HttpDeleteAttribute);
            case "HEAD":
                return typeof(HttpHeadAttribute);
            case "PATCH":
                return typeof(HttpPatchAttribute);
            case "OPTIONS":
                return typeof(HttpOptionsAttribute);
        }

        throw new NotSupportedException("unable to determine http method");
    }

AcquireSessionLockAttribute

[AttributeUsage(AttributeTargets.Method)]
public sealed class AcquireSessionLock : Attribute
{ }

Hook up the created controller factory in global.asax.cs

ControllerBuilder.Current.SetControllerFactory(typeof(DefaultReadOnlySessionStateControllerFactory));

Now, we can have both read-only and read-write session state in a single Controller.

public class TestController : Controller 
{
    [AcquireSessionLock]
    public ActionResult WriteSession()
    {
        var timeNow = DateTimeOffset.UtcNow.ToString();
        Session["key"] = timeNow;
        return Json(timeNow, JsonRequestBehavior.AllowGet);
    }

    public ActionResult ReadSession()
    {
        var timeNow = Session["key"];
        return Json(timeNow ?? "empty", JsonRequestBehavior.AllowGet);
    }
}

Note: ASPNET session state can still be written to even in readonly mode and will not throw any form of exception (It just doesn't lock to guarantee consistency) so we have to be careful to mark AcquireSessionLock in controller's actions that require writing session state.

You have a JSON Lines format text file. You need to parse your file line by line:

import json

data = []
with open('file') as f:
    for line in f:
        data.append(json.loads(line))

Each line contains valid JSON, but as a whole, it is not a valid JSON value as there is no top-level list or object definition.

Note that because the file contains JSON per line, you are saved the headaches of trying to parse it all in one go or to figure out a streaming JSON parser. You can now opt to process each line separately before moving on to the next, saving memory in the process. You probably don't want to append each result to one list and then process everything if your file is really big.

If you have a file containing individual JSON objects with delimiters in-between, use How do I use the 'json' module to read in one JSON object at a time? to parse out individual objects using a buffered method.

One solution that may work (it works for me) is to apply negative margin at input (textbox)... or fixed width for ie7 or to drop ie7 support. This results to pixel perfect width.. For me its 7 so i added 3 and 4 but it is still pixel perfect..

I had the same problem and i hated to have extra divs for border etc!

So here is my solution which seems to work!

You should use a ie7 only stylesheet to avoid the starhacks.

input.text{
    background-color: #fbfbfb;
    border : solid #eee 1px;
    width: 100%;
    -box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    height: 32px;

    *line-height:32px;
    *margin-left:-3px;
    *margin-right:-4px;
    display: inline;   
    padding: 0px 0 0 5px;

}

Every time you call e.nextElement() you take the next object from the iterator. You have to check e.hasMoreElement() between each call.

Example:

while(e.hasMoreElements()){
    String param = e.nextElement();
    System.out.println(param);
}

you can reduce the legend size setting:

plt.legend(labelspacing=y, handletextpad=x,fontsize)  

labelspacing is the vertical space between each label.

handletextpad is the distance between the actual legend and your label.

And fontsize is self-explanatory

Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)

Do it the other way around:

$a = "1,435";
$b = str_replace( ',', '', $a );

if( is_numeric( $b ) ) {
    $a = $b;
}

The easiest would be:

$var = intval(preg_replace('/[^\d.]/', '', $var));

or if you need float:

$var = floatval(preg_replace('/[^\d.]/', '', $var));

Create a CustomImageview then simply override its onDraw() method follows:

@Override
protected void onDraw(Canvas canvas) {

    float radius = this.getHeight()/2;
    Path path = new Path();
    RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
    path.addRoundRect(rect, radius, radius, Path.Direction.CW);
    canvas.clipPath(path);
    super.onDraw(canvas);

}

In case you want the code for the custom widget as well:-

CircularImageView.java

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Path;
import android.graphics.RectF;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

import androidx.annotation.Nullable;

public class CircularImageView extends ImageView {

    private Drawable image;

    public CircularImageView(Context context) {
        super(context);

        init(null, 0);
    }

    public CircularImageView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);

        init(attrs, 0);
    }

    public CircularImageView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);

        init(attrs, defStyleAttr);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        float radius = this.getHeight()/2;
        Path path = new Path();
        RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
        path.addRoundRect(rect, radius, radius, Path.Direction.CW);
        canvas.clipPath(path);
        super.onDraw(canvas);

    }

    private void init(AttributeSet attrs, int defStyle) {
        TypedArray a = Utils.CONTEXT.getTheme().obtainStyledAttributes(attrs, R.styleable.CircularImageView, 0, 0);
        try {
            image = a.getDrawable(R.styleable.CircularImageView_src);
        } finally {
            a.recycle();
        }

        this.setImageDrawable(image);
    }
}

Also, add the following code to your res/attrs.xml to create the required attribute:-

<declare-styleable name="CircularImageView">
        <attr name="src" format="reference" />
</declare-styleable>

Microsoft recognized the future web open source paradigm and decided to open .NET to other operating systems. .NET Core is a .NET Framework for Mac and Linux. It is a “lightweight” .NET Framework, so some features/libraries are missing.

On Windows, I would still run .NET Framework and Visual Studio 2015. .NET Core is more friendly with the open source world like Node.js, npm, Yeoman, Docker, etc.

You can develop full-fledged web sites and RESTful APIs on Mac or Linux with Visual Studio Code + .NET Core which wasn't possible before. So if you love Mac or Ubuntu and you are a .NET developer then go ahead and set it up.

For Mono vs. .NET Core, Mono was developed as a .NET Framework for Linux which is now acquired by Microsoft (company called Xamarin) and used in mobile development. Eventually, Microsoft may merge/migrate Mono to .NET Core. I would not worry about Mono right now.

Here's the way to do this via storyboard in XCode 10.2.1. Separator defaults to default which is the line. Set it to none to remove the line.

The stringi package provides the functions stri_count and stri_count_fixed which are very fast.

stringi::stri_count(q.data$string, fixed = "a")
# [1] 2 1 0

benchmark

Compared to the fastest approach from @42-'s answer and to the equivalent function from the stringr package for a vector with 30.000 elements.

library(microbenchmark)

benchmark <- microbenchmark(
  stringi = stringi::stri_count(test.data$string, fixed = "a"),
  baseR = nchar(test.data$string) - nchar(gsub("a", "", test.data$string, fixed = TRUE)),
  stringr = str_count(test.data$string, "a")
)

autoplot(benchmark)

data

q.data <- data.frame(number=1:3, string=c("greatgreat", "magic", "not"), stringsAsFactors = FALSE)
test.data <- q.data[rep(1:NROW(q.data), 10000),]

You may have to perform a diff and put document.getElementById('name') code inside a condition, in case your component is something like this:

// using the new hooks API
function Comp(props) {
  const { isLoading, data } = props;
  useEffect(() => {
    if (data) {
      var name = document.getElementById('name').value;
    }
  }, [data]) // this diff is necessary

  if (isLoading) return <div>isLoading</div>
  return (
    <div id='name'>Comp</div>
  );
}

If diff is not performed then, you will get null.

From the man page:

-d delim The first character of delim is used to terminate the input line, rather than newline.

You are using -d, which will terminate the input line on the comma. It will not read the rest of the line. That's why $y is empty.

let res = /^[a-zA-Z]+$/.test('sfjd');
console.log(res);

Note: If you have any punctuation marks or anything, those are all invalid too. Dashes and underscores are invalid. \w covers a-zA-Z and some other word characters. It all depends on what you need specifically.

Your code is passing a function as an argument to find. That function takes an element argument (of type Conversation) and returns void (meaning there is no return value). TypeScript describes this as (element: Conversation) => void'

What TypeScript is saying is that the find function doesn't expect to receive a function that takes a Conversation and returns void. It expects a function that takes a Conversations, a number and a Conversation array, and that this function should return a boolean.

So bottom line is that you either need to change your code to pass in the values to find correctly, or else you need to provide an overload to the definition of find in your definition file that accepts a Conversation and returns void.

If you use mod_rewrite to hide the extension of your scripts, or if you just like pretty URLs that end in /, then you might want to approach this from the other direction. Tell nginx to let anything with a non-static extension to go through to apache. For example:

location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|pdf|txt|tar|wav|bmp|rtf|js|flv|swf|html|htm)$
{
    root   /path/to/static-content;
}

location ~* ^!.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|pdf|txt|tar|wav|bmp|rtf|js|flv|swf|html|htm)$ {
    if (!-f $request_filename) {
        return 404;
    }
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

I found the first part of this snippet over at: http://code.google.com/p/scalr/wiki/NginxStatic

If you use "hg remove b" against a file with "A" status, which means it has been added but not commited, Mercurial will respond:

  not removing b: file has been marked for add (use forget to undo)

This response is a very clear explication of the difference between remove and forget.

My understanding is that "hg forget" is for undoing an added but not committed file so that it is not tracked by version control; while "hg remove" is for taking out a committed file from version control.

This thread has a example for using hg remove against files of 7 different types of status.

In my case I had to put textbox into a stack panel in order to stretch textbox on left side. Thanks to previous post. Just for an example I did set a background color to see what’s happens when window size is changing.

<StackPanel Name="JustContainer" VerticalAlignment="Center" HorizontalAlignment="Stretch" Background="BlueViolet" >
    <TextBox 
       Name="Input" Text="Hello World" 
       MaxWidth="300"
       HorizontalAlignment="Right"
       Width="{Binding ActualWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type FrameworkElement}}}">
    </TextBox>
</StackPanel>

I think you've pretty much nailed the points!

If you follow database design best practices and your primary key is never updatable (which I think should always be the case anyway), then you never really need the ON UPDATE CASCADE clause.

Zed made a good point, that if you use a natural key (e.g. a regular field from your database table) as your primary key, then there might be certain situations where you need to update your primary keys. Another recent example would be the ISBN (International Standard Book Numbers) which changed from 10 to 13 digits+characters not too long ago.

This is not the case if you choose to use surrogate (e.g. artifically system-generated) keys as your primary key (which would be my preferred choice in all but the most rare occasions).

So in the end: if your primary key never changes, then you never need the ON UPDATE CASCADE clause.

If you are using LINUX, you can use pyALSAAUDIO. For windows, we have PyAudio and there is also a library called SoundAnalyse.

I found an example for Linux here:

#!/usr/bin/python
## This is an example of a simple sound capture script.
##
## The script opens an ALSA pcm for sound capture. Set
## various attributes of the capture, and reads in a loop,
## Then prints the volume.
##
## To test it out, run it and shout at your microphone:

import alsaaudio, time, audioop

# Open the device in nonblocking capture mode. The last argument could
# just as well have been zero for blocking mode. Then we could have
# left out the sleep call in the bottom of the loop
inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE,alsaaudio.PCM_NONBLOCK)

# Set attributes: Mono, 8000 Hz, 16 bit little endian samples
inp.setchannels(1)
inp.setrate(8000)
inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)

# The period size controls the internal number of frames per period.
# The significance of this parameter is documented in the ALSA api.
# For our purposes, it is suficcient to know that reads from the device
# will return this many frames. Each frame being 2 bytes long.
# This means that the reads below will return either 320 bytes of data
# or 0 bytes of data. The latter is possible because we are in nonblocking
# mode.
inp.setperiodsize(160)

while True:
    # Read data from device
    l,data = inp.read()
    if l:
        # Return the maximum of the absolute value of all samples in a fragment.
        print audioop.max(data, 2)
    time.sleep(.001)

In the terminal: For Xcode 9.x and above

$ open /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app

For Xcode-beta 9.x and above

$ open /Applications/Xcode-beta.app/Contents/Developer/Applications/Simulator.app

You can't read the transaction log file easily because that's not properly documented. There are basically two ways to do this. Using undocumented or semi-documented database functions or using third-party tools.

Note: This only makes sense if your database is in full recovery mode.

SQL Functions:

DBCC LOG and fn_dblog - more details here and here.

Third-party tools:

Toad for SQL Server and ApexSQL Log.

You can also check out several other topics where this was discussed:

• Rollback transaction using transaction log

• SQL Server Transaction Log Explorer/Analyzer

• Read the log file (*.LDF) in SQL Server 2008

So - the solution of providing a base works given that all of the paths have the same base path. But if you want to provide different base paths, this still won't work.

One way I solved this problem was by making the beginning of the path relative. For your case:

gulp.src([
    'index.php',
    '*css/**/*',
    '*js/**/*',
    '*src/**/*',
])
.pipe(gulp.dest('/var/www/'));

The reason this works is that Gulp sets the base to be the end of the first explicit chunk - the leading * causes it to set the base at the cwd (which is the result that we all want!)

This only works if you can ensure your folder structure won't have certain paths that could match twice. For example, if you had randomjs/ at the same level as js, you would end up matching both.

This is the only way that I have found to include these as part of a top-level gulp.src function. It would likely be simple to create a plugin/function that could separate out each of those globs so you could specify the base directory for them, however.

Just go to your app/storage/logs there logs of error available. Go to filename of today's date time and you will find latest error in your application.

OR

Open app/config/app.php and change setting

'debug' => false,

To

'debug' => true, 

OR

Go to .env file to your application and change the configuratuion

APP_LOG_LEVEL=debug

You need to use delimiters with regexes in PHP. You can use the often used /, but PHP lets you use any matching characters, so @ and # are popular.

Further Reading.

If you are interpolating variables inside your regex, be sure to pass the delimiter you chose as the second argument to preg_quote().

import { Route, Redirect } from "react-router-dom";

class App extends Component {
  render() {
    return (
      <div>
        <Route path='/'>
          <Redirect to="/something" />
        </Route>
//rest of code here

this will make it so that when you load up the server on local host it will re direct you to /something

I usually start with something like:

set lines 256
set trimout on
set tab off

Have a look at help set if you have the help information installed. And then select name,address rather than select * if you really only want those two columns.

public static class Cloner
{
    public static T Clone<T>(this T item)
    {
        FieldInfo[] fis = item.GetType().GetFields(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);
        object tempMyClass = Activator.CreateInstance(item.GetType());
        foreach (FieldInfo fi in fis)
        {
            if (fi.FieldType.Namespace != item.GetType().Namespace)
                fi.SetValue(tempMyClass, fi.GetValue(item));
            else
            {
                object obj = fi.GetValue(item);
                if (obj != null)
                    fi.SetValue(tempMyClass, obj.Clone());
            }
        }
        return (T)tempMyClass;
    }
}

It is important to run your mongod command and keep the server running. If not, you will still be seeing this error.

I attach you my code:

const mongodb = require('mongodb')
const MongoClient = mongodb.MongoClient

const connectionURL = 'mongodb://127.0.0.1:27017'
const databaseName = 'task-manager'

MongoClient.connect(connectionURL, {useNewUrlParser: true, useUnifiedTopology: true}, (error, client) => {
    if(error) {
        return console.log('Error connecting to the server.')
    }

    console.log('Succesfully connected.')
})

There is a fundamental flaw in the way we think about web, especially when using MVC. The flaw is that JavaScript is somehow the view's responsibility. A view is a view, JavaScript (behavioral or otherwise) is JavaScript. In Silverlight and WPF's MVVM pattern we we're faced with "view first" or "model first". In MVC we should always try to reason from the model's standpoint and JavaScript is a part of this model in many ways.

I would suggest using the AMD pattern (I myself like RequireJS). Seperate your JavaScript in modules, define your functionality and hook into your html from JavaScript instead of relying on a view to load the JavaScript. This will clean up your code, seperate your concerns and make life easier all in one fell swoop.

You can use moment-duration-format plugin:

var seconds = 3820;
var duration = moment.duration(seconds, 'seconds');
var formatted = duration.format("hh:mm:ss");
console.log(formatted); // 01:03:40

<!-- Moment.js library -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

<!-- moment-duration-format plugin -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment-duration-format/1.3.0/moment-duration-format.min.js"></script>

See also this Fiddle

Upd: To avoid trimming for values less than 60-sec use { trim: false }:

var formatted = duration.format("hh:mm:ss", { trim: false }); // "00:00:05"

The URL is missing the protocol information. PHP thinks it is a filesystem path and tries to access the file at the specified location. However, the location doesn't actually exist in your filesystem and an error is thrown.

You'll need to add http or https at the beginning of the URL you're trying to get the contents from:

$json = json_decode(file_get_contents('http://...'));

As for the following error:

Unable to find the wrapper - did you forget to enable it when you configured PHP?

Your Apache installation probably wasn't compiled with SSL support. You could manually try to install OpenSSL and use it, or use cURL. I personally prefer cURL over file_get_contents(). Here's a function you can use:

function curl_get_contents($url)
{
  $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
  $data = curl_exec($ch);
  curl_close($ch);
  return $data;
}

Usage:

$url = 'https://...';
$json = json_decode(curl_get_contents($url));

For tasks of this type I usually use Crawller4j + Jsoup.

With crawler4j I download the pages from a domain, you can specify which ULR with a regular expression.

With jsoup, I "parsed" the html data you have searched for and downloaded with crawler4j.

Normally you can also download data with jsoup, but Crawler4J makes it easier to find links. Another advantage of using crawler4j is that it is multithreaded and you can configure the number of concurrent threads

https://github.com/yasserg/crawler4j/wiki

Some answers seem to be a little misleading.

You don't have to ...

• Assign a value to some static object when initializing, because assigning a value is Optional.
• Create another .cpp file for initializing since it can be done in the same Header file.

Also, you can even initialize a static object in the same class scope just like a normal variable using the inline keyword.

Initialize with no values in the same file

#include <string>
class A
{
    static std::string str;
    static int x;
};
std::string A::str;
int A::x;

Initialize with values in the same file

#include <string>
class A
{
    static std::string str;
    static int x;
};
std::string A::str = "SO!";
int A::x = 900;

Initialize in the same class scope using the inline keyword

#include <string>
class A
{
    static inline std::string str = "SO!";
    static inline int x = 900;
};

Yes, should try reinstall mysql, but use the --reinstall flag to force a package reconfiguration. So the operating system service configuration is not skipped:

sudo apt --reinstall install mysql-server

It's possible that you're creating your controls on the wrong thread. Consider the following documentation from MSDN:

This means that InvokeRequired can return false if Invoke is not required (the call occurs on the same thread), or if the control was created on a different thread but the control's handle has not yet been created.

In the case where the control's handle has not yet been created, you should not simply call properties, methods, or events on the control. This might cause the control's handle to be created on the background thread, isolating the control on a thread without a message pump and making the application unstable.

You can protect against this case by also checking the value of IsHandleCreated when InvokeRequired returns false on a background thread. If the control handle has not yet been created, you must wait until it has been created before calling Invoke or BeginInvoke. Typically, this happens only if a background thread is created in the constructor of the primary form for the application (as in Application.Run(new MainForm()), before the form has been shown or Application.Run has been called.

Let's see what this means for you. (This would be easier to reason about if we saw your implementation of SafeInvoke also)

Assuming your implementation is identical to the referenced one with the exception of the check against IsHandleCreated, let's follow the logic:

public static void SafeInvoke(this Control uiElement, Action updater, bool forceSynchronous)
{
    if (uiElement == null)
    {
        throw new ArgumentNullException("uiElement");
    }

    if (uiElement.InvokeRequired)
    {
        if (forceSynchronous)
        {
            uiElement.Invoke((Action)delegate { SafeInvoke(uiElement, updater, forceSynchronous); });
        }
        else
        {
            uiElement.BeginInvoke((Action)delegate { SafeInvoke(uiElement, updater, forceSynchronous); });
        }
    }
    else
    {    
        if (uiElement.IsDisposed)
        {
            throw new ObjectDisposedException("Control is already disposed.");
        }

        updater();
    }
}

Consider the case where we're calling SafeInvoke from the non-gui thread for a control whose handle has not been created.

uiElement is not null, so we check uiElement.InvokeRequired. Per the MSDN docs (bolded) InvokeRequired will return false because, even though it was created on a different thread, the handle hasn't been created! This sends us to the else condition where we check IsDisposed or immediately proceed to call the submitted action... from the background thread!

At this point, all bets are off re: that control because its handle has been created on a thread that doesn't have a message pump for it, as mentioned in the second paragraph. Perhaps this is the case you're encountering?

You can use this function:

int arraySize(char array[])
{
    int cont = 0;
    for (int i = 0; array[i] != 0; i++)
            cont++;
    return cont;
}

HTML:

<input name="name" id="name" type="text" value="Name" onfocus="clearField(this);" onblur="fillField(this);"/>

JS:

function clearField(input) {
  if(input.value=="Name") { //Only clear if value is "Name"
    input.value = "";
  }
}
function fillField(input) {
    if(input.value=="") {
        input.value = "Name";
    }
}

For people using Tiny Core Linux, you also need to install libtool-dev as it has the *.m4 files needed for libtoolize.

My problem was

Error: Could not symlink share/man/man7/ABORT.7
/usr/local/share/man/man7 is not writable.

chown didn't help, but i followed running brew doctor advices and this warning helped me:

After brew prune all worked fine!

Django-model-values (disclosure: author) provides an implementation of the NotEqual lookup, as in this answer. It also provides syntactic support for it:

from model_values import F
Model.objects.exclude(F.x != 5, a=True)

Header files can contain any valid C code, since they are injected into the compilation unit by the pre-processor prior to compilation.

If a header file contains a function, and is included by multiple .c files, each .c file will get a copy of that function and create a symbol for it. The linker will complain about the duplicate symbols.

It is technically possible to create static functions in a header file for inclusion in multiple .c files. Though this is generally not done because it breaks from the convention that code is found in .c files and declarations are found in .h files.

See the discussions in C/C++: Static function in header file, what does it mean? for more explanation.

Hi. As per my knowledge let me clear the concept of default constructor:

The compiler automatically provides a no-argument, default constructor for any class without constructors. This default constructor will call the no-argument constructor of the superclass. In this situation, the compiler will complain if the superclass doesn't have a no-argument constructor so you must verify that it does. If your class has no explicit superclass, then it has an implicit superclass of Object, which does have a no-argument constructor.

I read this information from the Java Tutorials.

<?php
$start = microtime(true);
for ($i = 0; $i < 10000000; $i++) {
    $a = 'a';
    $a = NULL;
}
$elapsed = microtime(true) - $start;

echo "took $elapsed seconds\r\n";



$start = microtime(true);
for ($i = 0; $i < 10000000; $i++) {
    $a = 'a';
    unset($a);
}
$elapsed = microtime(true) - $start;

echo "took $elapsed seconds\r\n";
?>

Per that it seems like "= null" is faster.

PHP 5.4 results:

PHP 5.1 results:

• took 2.6272349357605 seconds
• took 5.0403649806976 seconds

Things start to look different with PHP 5.0 and 4.4.

5.0:

• took 10.038941144943 seconds
• took 7.0874409675598 seconds

4.4:

• took 7.5352551937103 seconds
• took 6.6245851516724 seconds

Keep in mind microtime(true) doesn't work in PHP 4.4 so I had to use the microtime_float example given in php.net/microtime / Example #1.

Calling JavaScript function on code behind i.e. On Page_Load

ClientScript.RegisterStartupScript(GetType(), "Javascript", "javascript:FUNCTIONNAME(); ", true);

If you have UpdatePanel there then try like this

ScriptManager.RegisterStartupScript(GetType(), "Javascript", "javascript:FUNCTIONNAME(); ", true);

DbContext has a constructor overload that accepts the name of a connection string or a connection string itself. Implement your own version and pass it to the base constructor:

public class MyDbContext : DbContext
{
    public MyDbContext( string nameOrConnectionString ) 
        : base( nameOrConnectionString )
    {
    }
}

Then simply pass the name of a configured connection string or a connection string itself when you instantiate your DbContext

var context = new MyDbContext( "..." );

Use 'dd-mon-yyyy' if you are using the 2nd date format specified in your answer. Ex:

to_date(<column name>,'dd-mon-yyyy')

With the help of ProgrammersBlock posts I came up with this. My needs were slightly different. I needed to take a string and return it as a LocalDate object. I was handed code that was using the older Calendar and SimpleDateFormat. I wanted to make it a little more current. This is what I came up with.

    import java.time.LocalDate;
    import java.time.format.DateTimeFormatter;


    void ExampleFormatDate() {

    LocalDate formattedDate = null;  //Declare LocalDate variable to receive the formatted date.
    DateTimeFormatter dateTimeFormatter;  //Declare date formatter
    String rawDate = "2000-01-01";  //Test string that holds a date to format and parse.

    dateTimeFormatter = DateTimeFormatter.ISO_LOCAL_DATE;

    //formattedDate.parse(String string) wraps the String.format(String string, DateTimeFormatter format) method.
    //First, the rawDate string is formatted according to DateTimeFormatter.  Second, that formatted string is parsed into
    //the LocalDate formattedDate object.
    formattedDate = formattedDate.parse(String.format(rawDate, dateTimeFormatter));

}

Hopefully this will help someone, if anyone sees a better way of doing this task please add your input.

This might be just a requirement of PyMySql in Python, but I found that I had to name the exact table that I wanted the ID for:

In:

cnx = pymysql.connect(host='host',
                            database='db',
                            user='user',
                            password='pass')
cursor = cnx.cursor()
update_batch = """insert into batch set type = "%s" , records = %i, started = NOW(); """
second_query = (update_batch % ( "Batch 1", 22  ))
cursor.execute(second_query)
cnx.commit()
batch_id = cursor.execute('select last_insert_id() from batch')
cursor.close()

batch_id

Out: 5
... or whatever the correct Batch_ID value actually is

You have to use HTML in your webView in this case. I solved this using following code

webView.loadDataWithBaseURL(null,
                "<!DOCTYPE html><html><body style = \"text-align:center\"><img src= "
                        + \"http://www.koenvangorp.be/photos/2005_09_16-moon_2000.jpg\"
                        + " alt=\"pageNo\" width=\"100%\"></body></html>",
                "text/html", "UTF-8", null);

If you are using Razor view engine then edit the _Layout.cshtml file. Move the @Scripts.Render("~/bundles/jquery") present in footer to the header section and write the javascript / jquery code as you want:

@Scripts.Render("~/bundles/jquery")
<script type="text/javascript">
    $(document).ready(function () {
        var divLength = $('div').length;
        alert(divLength);
    });
</script>

I wrapped around $state around $timeout and it worked for me.

For example,

(function() {
  'use strict';

  angular
    .module('app')
    .controller('BodyController', BodyController);

  BodyController.$inject = ['$state', '$timeout'];

  /* @ngInject */
  function BodyController($state, $timeout) {
    $timeout(function(){
      console.log($state.current);
    });

  }
})();

I have found the following code to be the most consistent, performant, and simple.

var scripts = document.getElementsByTagName('script');
var thisScript = null;
var i = scripts.length;
while (i--) {
  if (scripts[i].src && (scripts[i].src.indexOf('yourscript.js') !== -1)) {
    thisScript = scripts[i];
    break;
  }
}
console.log(thisScript);

Your code works just fine. It's most likely the window thats not focused. I use a similar function to close iframe boxes etc.

$(document).ready(function(){

    // Set focus
    setTimeout('window.focus()',1000);

});

$(document).keypress(function(e) {

    // Enable esc
    if (e.keyCode == 27) {
      parent.document.getElementById('iframediv').style.display='none';
      parent.document.getElementById('iframe').src='/views/view.empty.black.html';
    }

});

Kafka requires zookeeper and indeed the list of topics is stored there, hence the kafka-topics tool needs to connect to zookeeper too. kafka-clients apis in the newer versions no longer talk to zookeeper directly, perhaps that's why you're under the impression a setup without zookeeper is possible. It is not, as kafka relies on it internally. For reference see: http://kafka.apache.org/documentation.html#quickstart Step 2:

Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don't already have one

Image.onload() will often work.

To use it, you'll need to be sure to bind the event handler before you set the src attribute.

Sample code for case: @throw([NSException exceptionWithName:...

- (void)parseError:(NSError *)error
       completionBlock:(void (^)(NSString *error))completionBlock {


    NSString *resultString = [NSString new];

    @try {

    NSData *errorData = [NSData dataWithData:error.userInfo[@"SomeKeyForData"]];

    if(!errorData.bytes) {

        @throw([NSException exceptionWithName:@"<Set Yours exc. name: > Test Exc" reason:@"<Describe reason: > Doesn't contain data" userInfo:nil]);
    }


    NSDictionary *dictFromData = [NSJSONSerialization JSONObjectWithData:errorData
                                                                 options:NSJSONReadingAllowFragments
                                                                   error:&error];

    resultString = dictFromData[@"someKey"];
    ...


} @catch (NSException *exception) {

      NSLog( @"Caught Exception Name: %@", exception.name);
      NSLog( @"Caught Exception Reason: %@", exception.reason );

    resultString = exception.reason;

} @finally {

    completionBlock(resultString);
}

}

Using:

[self parseError:error completionBlock:^(NSString *error) {
            NSLog(@"%@", error);
        }];

Another more advanced use-case:

- (void)parseError:(NSError *)error completionBlock:(void (^)(NSString *error))completionBlock {

NSString *resultString = [NSString new];

NSException* customNilException = [NSException exceptionWithName:@"NilException"
                                                          reason:@"object is nil"
                                                        userInfo:nil];

NSException* customNotNumberException = [NSException exceptionWithName:@"NotNumberException"
                                                                reason:@"object is not a NSNumber"
                                                              userInfo:nil];

@try {

    NSData *errorData = [NSData dataWithData:error.userInfo[@"SomeKeyForData"]];

    if(!errorData.bytes) {

        @throw([NSException exceptionWithName:@"<Set Yours exc. name: > Test Exc" reason:@"<Describe reason: > Doesn't contain data" userInfo:nil]);
    }


    NSDictionary *dictFromData = [NSJSONSerialization JSONObjectWithData:errorData
                                                                 options:NSJSONReadingAllowFragments
                                                                   error:&error];

    NSArray * array = dictFromData[@"someArrayKey"];

    for (NSInteger i=0; i < array.count; i++) {

        id resultString = array[i];

        if (![resultString isKindOfClass:NSNumber.class]) {

            [customNotNumberException raise]; // <====== HERE is just the same as: @throw customNotNumberException;

            break;

        } else if (!resultString){

            @throw customNilException;        // <======

            break;
        }

    }

} @catch (SomeCustomException * sce) {
    // most specific type
    // handle exception ce
    //...
} @catch (CustomException * ce) {
    // most specific type
    // handle exception ce
    //...
} @catch (NSException *exception) {
    // less specific type

    // do whatever recovery is necessary at his level
    //...
    // rethrow the exception so it's handled at a higher level

    @throw (SomeCustomException * customException);

} @finally {
    // perform tasks necessary whether exception occurred or not

}

With CSS this can be achieve easily.

<div ng-repeat="item in items">
<span style="white-space:pre-wrap;"> {{item.description}}</span>
</div>  

Or a CSS class can be created for this purpose and can be used from external CSS file
