Compare Names containing apostrophe in DB through Java code

String sql="select lastname  from employee where FirstName like '%"+firstName.trim().toLowerCase().replaceAll("'", "''")+"%'"

statement = conn.createStatement();
        rs=statement.executeQuery(Sql);

iterate the results.

It's HTML character references for encoding a character by its decimal code point

Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe

I don't think that one is better than the other in general; it depends on how you intend to use it.

• If you want to store it in a DB column that has a charset/collation that does not support the right single quote character, you may run into storing it as the multi-byte character instead of 7-bit ASCII (’).
• If you are displaying it on an html element that specifies a charset that does not support it, it may not display in either case.
• If many developers are going to be editing/viewing this file with editors/keyboards that do not support properly typing or displaying the character, you may want to use the entity
• If you need to convert the file between various character encodings or formats, you may want to use the entity
• If your HTML code may escape entities improperly, you may want to use the character.

In general I would lean more towards using the character because as you point out it is easier to read and type.

Password Requirement :

• Password should be at least eight (8) characters in length where the system can support it.

• Passwords must include characters from at least two (2) of these groupings: alpha, numeric, and special characters.

  ^.*(?=.{8,})(?=.*\d)(?=.*[a-zA-Z])|(?=.{8,})(?=.*\d)(?=.*[!@#$%^&])|(?=.{8,})(?=.*[a-zA-Z])(?=.*[!@#$%^&]).*$
  

I tested it and it works

For this (and most plotting) I would not rely on the Pandas wrappers to matplotlib. Instead, just use matplotlib directly:

import matplotlib.pyplot as plt
plt.scatter(df['col_name_1'], df['col_name_2'])
plt.show() # Depending on whether you use IPython or interactive mode, etc.

and remember that you can access a NumPy array of the column's values with df.col_name_1.values for example.

I ran into trouble using this with Pandas default plotting in the case of a column of Timestamp values with millisecond precision. In trying to convert the objects to datetime64 type, I also discovered a nasty issue: < Pandas gives incorrect result when asking if Timestamp column values have attr astype >.

Use count(d.ertek) or count(d.id) instead of count(d). This can be happen when you have composite primary key at your entity.

There actually seems to be a method in GMap3. It's a static method of the google.maps.geometry.spherical namespace.

It takes as arguments two LatLng objects and will utilize a default Earth radius of 6378137 meters, although the default radius can be overridden with a custom value if necessary.

Make sure you include:

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&v=3&libraries=geometry"></script>

in your head section.

The call will be:

google.maps.geometry.spherical.computeDistanceBetween (latLngA, latLngB);

You can try this:

SELECT DATE(DATE_ADD(m_inv_reqdate, INTERVAL + 1 DAY)) FROM  tr08_investment

It's because you aren't giving the un-hovered state a right attribute.

right isn't set so it's trying to go from nothing to 0px. Obviously because it has nothing to go to, it just 'warps' over.

If you give the unhovered state a right:90%;, it will transition how you like.

Just as a side note, if you still want it to be on the very left of the page, you can use the calc css function.

Example:

right: calc(100% - 100px)
                     ^ width of div

You don't have to use left then.

Also, you can't transition using left or right auto and will give the same 'warp' effect.

div {_x000D_
    width:100px;_x000D_
    height:100px;_x000D_
    background:red;_x000D_
    transition:2s;_x000D_
    -webkit-transition:2s;_x000D_
    -moz-transition:2s;_x000D_
    position:absolute;_x000D_
    right:calc(100% - 100px);_x000D_
}_x000D_
div:hover {_x000D_
  right:0;_x000D_
}

<p>_x000D_
  <b>Note:</b> This example does not work in Internet Explorer 9 and earlier versions._x000D_
</p>_x000D_
<div></div>_x000D_
<p>Hover over the red square to see the transition effect.</p>

CanIUse says that the calc() function only works on IE10+

There are instructions on how to install sshpass here:

https://gist.github.com/arunoda/7790979

For Mac you will need to install xcode and command line tools then use the unofficial Homewbrew command:

brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

Use Numpy direct array indexing, as in MATLAB, Julia, ...

a = [10, 11, 12, 13, 14, 15];
s = [1, 2, 5] ;

import numpy as np
list(np.array(a)[s])
# [11, 12, 15]

Better yet, just stay with Numpy arrays

a = np.array([10, 11, 12, 13, 14, 15])
a[s]
#array([11, 12, 15])

Implementing the SearchView without the use of the menu.xml file and open through button

In your Activity we need to use the method of the onCreateOptionsMenumethod in which we will programmatically inflate the SearchView

private MenuItem searchMenu;
private String mSearchString="";

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);

        SearchManager searchManager = (SearchManager) StoreActivity.this.getSystemService(Context.SEARCH_SERVICE);


        SearchView mSearchView = new SearchView(getSupportActionBar().getThemedContext());
        mSearchView.setQueryHint(getString(R.string.prompt_search)); /// YOUR HINT MESSAGE
        mSearchView.setMaxWidth(Integer.MAX_VALUE);

        searchMenu = menu.add("searchMenu").setVisible(false).setActionView(mSearchView);
        searchMenu.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);


        assert searchManager != null;
        mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        mSearchView.setIconifiedByDefault(false);

        SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
            public boolean onQueryTextChange(String newText) {
                mSearchString = newText;

                return true;
            }

            public boolean onQueryTextSubmit(String query) {
                mSearchString = query;

                searchMenu.collapseActionView();


                return true;
            }
        };

        mSearchView.setOnQueryTextListener(queryTextListener);


        return true;
    }

And in your Activity class, you can open the SearchView on any button click on toolbar like below

YOUR_BUTTON.setOnClickListener(view -> {

            searchMenu.expandActionView();

        });

// set the background to green
v.setBackgroundColor(0x0000FF00 );
v.invalidate();

The code does not set the button to green. Instead, it makes the button totally invisible.

Explanation: the hex value of the color is wrong. With an Alpha value of zero, the color will be invisible.

The correct hex value is 0xFF00FF00 for full opacity green. Any Alpha value between 00 and FF would cause transparency.

I think u want to change the default settings of android studio. Whenever a layout or Activity in created u want to create "RelativeLayout" by default. In that case, flow the step below

1. click any folder u used to create layout or Activity
2. then "New>> Edit File Templates
3. then go to "Other" tab
4. select "LayoutResourceFile.xml" and "LayoutResourceFile_vertical.xml"
5. change "${ROOT_TAG}" to "RelativeLayout"
6. click "Ok"

you are done

To remove all Untrack files. Try this terminal command

 git clean -fdx

You can use a linear gradient:

div {_x000D_
    width:100px;_x000D_
    height:50px;_x000D_
    display:block;_x000D_
    background-image: linear-gradient(to right, #000 1px, rgba(255,255,255,0) 1px), linear-gradient(to left, #000 0.1rem, rgba(255,255,255,0) 1px);_x000D_
 background-position: bottom;_x000D_
 background-size: 100% 25px;_x000D_
 background-repeat: no-repeat;_x000D_
    border-bottom: 1px solid #000;_x000D_
    border-top: 1px solid red;_x000D_
}

<div></div>

Basically you'd need to iterate over the map's entry set, remembering both the "currently known maximum" and the key associated with it. (Or just the entry containing both, of course.)

For example:

Map.Entry<Foo, Bar> maxEntry = null;

for (Map.Entry<Foo, Bar> entry : map.entrySet())
{
    if (maxEntry == null || entry.getValue().compareTo(maxEntry.getValue()) > 0)
    {
        maxEntry = entry;
    }
}

Difference in DLL and EXE:

1) DLL is an In-Process Component which means running in the same memory space as the client process. EXE is an Out-Process Component which means it runs in its own separate memory space.

2) The DLL contains functions and procedures that other programs can use (promotes reuability) while EXE cannot be shared with other programs.

3) DLL cannot be directly executed as they're designed to be loaded and run by other programs. EXE is a program that is executed directly.

If you are not wanting to use images, and want it to look exactly like the Rounded Rect style, try this. Just place a UIView over the UIButton, with an identical frame and auto resize mask, set the alpha to 0.3, and set the background to a color. Then use the snippet below to clip the rounded edges off the colored overlay view. Also, uncheck the 'User Interaction Enabled' checkbox in IB on the UIView to allow touch events to cascade down to the UIButton underneath.

One side effect is that your text will also be colorized.

#import <QuartzCore/QuartzCore.h>

colorizeOverlayView.layer.cornerRadius = 10.0f;
colorizeOverlayView.layer.masksToBounds = YES;

If you want to match an expression starting with [ and ending with ], use \[[^\]]*\].

Having: It applies filter conditions to each group of rows. Where: It applies a filter of individual rows.

First and Last Date of current Month In the moment.js

console.log("current month first date");
    const firstdate = moment().startOf('month').format('DD-MM-YYYY');
console.log(firstdate);

console.log("current month last date");
    const lastdate=moment().endOf('month').format("DD-MM-YYYY"); 
console.log(lastdate); 

You can use the dplyr package to easily remove those particular rows.

library(dplyr)
df <- filter(df, C != "Foo")

Somthing like this should workL

SELECT BookingId, StartTime
FROM Booking
WHERE StartTime between dateadd(hour, -1, getdate()) and getdate()

I would use ruby-build with rbenv. The following lines install Ruby 3.0.0 and set it as your default Ruby version:

$ brew update
$ brew install ruby-build
$ brew install rbenv

$ rbenv install 3.0.0
$ rbenv global 3.0.0

Its a new operator for combined comparison. Similar to strcmp() or version_compare() in behavior, but it can be used on all generic PHP values with the same semantics as <, <=, ==, >=, >. It returns 0 if both operands are equal, 1 if the left is greater, and -1 if the right is greater. It uses exactly the same comparison rules as used by our existing comparison operators: <, <=, ==, >= and >.

Based on Pumbaa80's answer I have modified the code to use the console.log colours (working on Chrome for sure) and not HTML. Output can be seen inside console. You can edit the _variables inside the function adding some more styling.

function JSONstringify(json) {
    if (typeof json != 'string') {
        json = JSON.stringify(json, undefined, '\t');
    }

    var 
        arr = [],
        _string = 'color:green',
        _number = 'color:darkorange',
        _boolean = 'color:blue',
        _null = 'color:magenta',
        _key = 'color:red';

    json = json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function (match) {
        var style = _number;
        if (/^"/.test(match)) {
            if (/:$/.test(match)) {
                style = _key;
            } else {
                style = _string;
            }
        } else if (/true|false/.test(match)) {
            style = _boolean;
        } else if (/null/.test(match)) {
            style = _null;
        }
        arr.push(style);
        arr.push('');
        return '%c' + match + '%c';
    });

    arr.unshift(json);

    console.log.apply(console, arr);
}

Here is a bookmarklet you can use:

javascript:function JSONstringify(json) {if (typeof json != 'string') {json = JSON.stringify(json, undefined, '\t');}var arr = [],_string = 'color:green',_number = 'color:darkorange',_boolean = 'color:blue',_null = 'color:magenta',_key = 'color:red';json = json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function (match) {var style = _number;if (/^"/.test(match)) {if (/:$/.test(match)) {style = _key;} else {style = _string;}} else if (/true|false/.test(match)) {style = _boolean;} else if (/null/.test(match)) {style = _null;}arr.push(style);arr.push('');return '%c' + match + '%c';});arr.unshift(json);console.log.apply(console, arr);};void(0);

Usage:

var obj = {a:1, 'b':'foo', c:[false,null, {d:{e:1.3e5}}]};
JSONstringify(obj);

Edit: I just tried to escape the % symbol with this line, after the variables declaration:

json = json.replace(/%/g, '%%');

But I find out that Chrome is not supporting % escaping in the console. Strange... Maybe this will work in the future.

Cheers!

I tried with a rest client.

it works fine. I retrieve 200 OK with a good body.

Why do you set a status code in your request? and multiple declaration "Accept" with Accept:application/json,application/json,application/jsonrequest. just a statement is enough.

Your URL probably has ampersands in it. I had this problem, too, and I realized that my URL was full of ampersands (from CGI variables being passed) and so everything was getting sent to background in a weird way and thus not redirecting properly. If you put quotes around the URL it will fix it.

I used the following code to apply some external CSS:

boxText = document.createElement("html");
boxText.innerHTML = "<head><link rel='stylesheet' href='style.css'/></head><body>[some html]<body>";

infowindow.setContent(boxText);
infowindow.open(map, marker);

simply run the following command:

ng update

note: this will not update globally.

A couple of observations:

• Don't create simple delegates explicitly in code like that unless you're pre-2.0 so you could use:

   BeginInvoke(new EventHandler<CoolObjectEventArgs>(mCoolObject_CoolEvent), 
               sender, 
               args);

• Also you don't need to create and populate the object array because the args parameter is a "params" type so you can just pass in the list.

• I would probably favor Invoke over BeginInvoke as the latter will result in the code being called asynchronously which may or may not be what you're after but would make handling subsequent exceptions difficult to propagate without a call to EndInvoke. What would happen is that your app will end up getting a TargetInvocationException instead.

I use Iesi.Collections http://www.codeproject.com/KB/recipes/sets.aspx

It's used in lot of OSS projects, I first came across it in NHibernate

The difference between a non-lateral and a lateral join lies in whether you can look to the left hand table's row. For example:

select  *
from    table1 t1
cross join lateral
        (
        select  *
        from    t2
        where   t1.col1 = t2.col1 -- Only allowed because of lateral
        ) sub

This "outward looking" means that the subquery has to be evaluated more than once. After all, t1.col1 can assume many values.

By contrast, the subquery after a non-lateral join can be evaluated once:

select  *
from    table1 t1
cross join
        (
        select  *
        from    t2
        where   t2.col1 = 42 -- No reference to outer query
        ) sub

As is required without lateral, the inner query does not depend in any way on the outer query. A lateral query is an example of a correlated query, because of its relation with rows outside the query itself.

EDIT: Added passing a model up to the server in the file post.

The form data in the input elements would be sent in the data property of the post and be available as normal form values.

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

You could use: cordova plugins list | awk '{print $1}' | xargs cordova plugins rm

and use cordova plugins list to verify if plugins are all removed.

Write below function to get date in string, convert and return in string format.

getParsedDate(strDate){
    var strSplitDate = String(strDate).split(' ');
    var date = new Date(strSplitDate[0]);
    // alert(date);
    var dd = date.getDate();
    var mm = date.getMonth() + 1; //January is 0!

    var yyyy = date.getFullYear();
    if (dd < 10) {
        dd = '0' + dd;
    }
    if (mm < 10) {
        mm = '0' + mm;
    }
    date =  dd + "-" + mm + "-" + yyyy;
    return date.toString();
}

Print it where you required: Date : {this.getParsedDate(stringDate)}

Googling around for Groovy ways to "cast" a String to a Date, I came across this article: http://www.goodercode.com/wp/intercept-method-calls-groovy-type-conversion/

The author uses Groovy metaMethods to allow dynamically extending the behavior of any class' asType method. Here is the code from the website.

class Convert {
    private from
    private to

    private Convert(clazz) { from = clazz }
    static def from(clazz) {
        new Convert(clazz)
    }

    def to(clazz) {
        to = clazz
        return this
    }

    def using(closure) {
        def originalAsType = from.metaClass.getMetaMethod('asType', [] as Class[])
        from.metaClass.asType = { Class clazz ->
            if( clazz == to ) {
                closure.setProperty('value', delegate)
                closure(delegate)
            } else {
                originalAsType.doMethodInvoke(delegate, clazz)
            }
        }
    }
}

They provide a Convert class that wraps the Groovy complexity, making it trivial to add custom as-based type conversion from any type to any other:

Convert.from( String ).to( Date ).using { new java.text.SimpleDateFormat('MM-dd-yyyy').parse(value) }

def christmas = '12-25-2010' as Date

It's a convenient and powerful solution, but I wouldn't recommend it to someone who isn't familiar with the tradeoffs and pitfalls of tinkering with metaClasses.

I've recently battled with this problem as well, and I've learned two things about the above suggestions.

1. Setting the numberFormatting to @ causes Excel to left-align the value, and read it as if it were text, however, it still truncates the leading zero.
2. Adding an apostrophe at the beginning results in Excel treating it as text and retains the zero, and then applies the default text format, solving both problems.

The misleading aspect of this is that you now have a different value in the cell. Fortuately, when you copy/paste or export to CSV, the apostrophe is not included.

Conclusion: use the apostrophe, not the numberFormatting in order to retain the leading zeros.

If the structs only contain primitives or if you are interested in strict equality then you can do something like this:

int my_struct_cmp(const struct my_struct * lhs, const struct my_struct * rhs)
{
    return memcmp(lhs, rsh, sizeof(struct my_struct));
}

However, if your structs contain pointers to other structs or unions then you will need to write a function that compares the primitives properly and make comparison calls against the other structures as appropriate.

Be aware, however, that you should have used memset(&a, sizeof(struct my_struct), 1) to zero out the memory range of the structures as part of your ADT initialization.

For demo code that conforms to POSIX standard as described in Setting Terminal Modes Properly and Serial Programming Guide for POSIX Operating Systems, the following is offered.
This code should execute correctly using Linux on x86 as well as ARM (or even CRIS) processors.
It's essentially derived from the other answer, but inaccurate and misleading comments have been corrected.

This demo program opens and initializes a serial terminal at 115200 baud for non-canonical mode that is as portable as possible.
The program transmits a hardcoded text string to the other terminal, and delays while the output is performed.
The program then enters an infinite loop to receive and display data from the serial terminal.
By default the received data is displayed as hexadecimal byte values.

To make the program treat the received data as ASCII codes, compile the program with the symbol DISPLAY_STRING, e.g.

 cc -DDISPLAY_STRING demo.c

If the received data is ASCII text (rather than binary data) and you want to read it as lines terminated by the newline character, then see this answer for a sample program.

For an example of an efficient program that provides buffering of received data yet allows byte-by-byte handing of the input, then see this answer.

Here is javascript I wrote to do just this.

function ImageTile(parentdiv, imagediv) {
imagediv.style.position = 'absolute';

function load(image) {
    //
    // Reset to auto so that when the load happens it resizes to fit our image and that
    // way we can tell what size our image is. If we don't do that then it uses the last used
    // values to auto-size our image and we don't know what the actual size of the image is.
    //
    imagediv.style.height = "auto";
    imagediv.style.width = "auto";
    imagediv.style.top = 0;
    imagediv.style.left = 0;

    imagediv.src = image;
}

//bind load event (need to wait for it to finish loading the image)
imagediv.onload = function() {
    var vpWidth = parentdiv.clientWidth;
    var vpHeight = parentdiv.clientHeight;
    var imgWidth = this.clientWidth;
    var imgHeight = this.clientHeight;

    if (imgHeight > imgWidth) {
        this.style.height = vpHeight + 'px';
        var width = ((imgWidth/imgHeight) * vpHeight);
        this.style.width = width + 'px';
        this.style.left = ((vpWidth - width)/2) + 'px';
    } else {
        this.style.width = vpWidth + 'px';
        var height = ((imgHeight/imgWidth) * vpWidth);
        this.style.height = height + 'px';
        this.style.top = ((vpHeight - height)/2) + 'px';
    }
};

return {
    "load": load
};

}

And to use it just do something like this:

 var tile1 = ImageTile(document.documentElement, document.getElementById("tile1"));
 tile1.load(url);

I use this for a slideshow in which I have two of these "tiles" and I fade one out and the other in. The loading is done on the "tile" that is not visible to avoid the jarring visual affect of the resetting of the style back to "auto".

This article http://technet.microsoft.com/en-us/library/ee198810.aspx led me to the solution. The only change is the placement of the exclamation mark.

(!manager=*)

It seems to be working just as wanted.

With Stream API you can do something like this:

List<String> aWithoutB = a.stream()
    .filter(element -> !b.contains(element))
    .collect(Collectors.toList());

List<String> bWithoutA = b.stream()
    .filter(element -> !a.contains(element))
    .collect(Collectors.toList());

To get rid of the outline when clicking, add outline:none

Php has an inbuilt JSON Serialising function.

json_encode

json_encode

Please use that if you can and don't suffer Not Invented Here syndrome.

Alternatively you can check connection status by logging into Mongo Atlas and then navigating to your cluster.

You should add namespace if you are not using it:

System.Windows.Forms.MessageBox.Show("Some text", "Some title", 
    System.Windows.Forms.MessageBoxButtons.OK, 
    System.Windows.Forms.MessageBoxIcon.Error);

Alternatively, you can add at the begining of your file:

using System.Windows.Forms

and then use (as stated in previous answers):

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

From the Sonatype doc:

The answer to this question depends on your own perspective. The great majority of Maven users are going to call Maven a “build tool”: a tool used to build deployable artifacts from source code. Build engineers and project managers might refer to Maven as something more comprehensive: a project management tool. What is the difference? A build tool such as Ant is focused solely on preprocessing, compilation, packaging, testing, and distribution. A project management tool such as Maven provides a superset of features found in a build tool. In addition to providing build capabilities, Maven can also run reports, generate a web site, and facilitate communication among members of a working team.

I'd strongly recommend looking at the Sonatype doc and spending some time looking at the available plugins to understand the power of Maven.

Very briefly, it operates at a higher conceptual level than (say) Ant. With Ant, you'd specify the set of files and resources that you want to build, then specify how you want them jarred together, and specify the order that should occur in (clean/compile/jar). With Maven this is all implicit. Maven expects to find your files in particular places, and will work automatically with that. Consequently setting up a project with Maven can be a lot simpler, but you have to play by Maven's rules!

I had the a similar problem and want to share my solution here.

I have the following HTML:

<div data-my-directive>
  <div id='sub' ng-include='includedFile.htm'></div>
</div>

Problem: In the link-function of directive of the parent div I wanted to jquery'ing the child div#sub. But it just gave me an empty object because ng-include hadn't finished when link function of directive ran. So first I made a dirty workaround with $timeout, which worked but the delay-parameter depended on client speed (nobody likes that).

Works but dirty:

app.directive('myDirective', [function () {
    var directive = {};
    directive.link = function (scope, element, attrs) {
        $timeout(function() {
            //very dirty cause of client-depending varying delay time 
            $('#sub').css(/*whatever*/);
        }, 350);
    };
    return directive;
}]);

Here's the clean solution:

app.directive('myDirective', [function () {
    var directive = {};
    directive.link = function (scope, element, attrs) {
        scope.$on('$includeContentLoaded', function() {
            //just happens in the moment when ng-included finished
            $('#sub').css(/*whatever*/);
        };
    };
    return directive;
}]);

Maybe it helps somebody.

I found a solution that is similar to the one with psexec but works without additional tools and survives a reboot.

Just add a sheduled task, insert "system" in the "run as" field and point the task to a batch file with the simple command

net use z: \servername\sharedfolder /persistent:yes

Then select "run at system startup" (or similar, I do not have an English version) and you are done.

I my case, the button was working for two of 8 links. My solution was

$("body,html,document").animate({scrollTop:$("#myLocation").offset().top},2500);

This created a nice scroll effect as well

You can add a class to the button and put some script redirecting it.

I do it this way:

<button class='buttonClass'>button name</button>

<script>
$(".buttonClass').click(function(){
window.location.href = "http://stackoverflow.com";
});
</script>

I know this is and old question, but i was faced with the same problem recently and none of the answers worked for me:

• Couldn't find an old Foxit Reader version
• As @pilkch said 2Printer adds a report page
• Adobe Reader opens a gui

After searching a little more i found this: http://www.columbia.edu/~em36/pdftoprinter.html.

It's a simple exe that you call with the filename and it prints to the default printer (or one that you specify). From the site:

PDFtoPrinter is a program for printing PDF files from the Windows command line. The program is designed generally for the Windows command line and also for use with the vDos DOS emulator.

To print a PDF file to the default Windows printer, use this command:

PDFtoPrinter.exe filename.pdf

To print to a specific printer, add the name of the printer in quotation marks:

PDFtoPrinter.exe filename.pdf "Name of Printer"

If you want to print to a network printer, use the name that appears in Windows print dialogs, like this (and be careful to note the two backslashes at the start of the name and the single backslash after the servername):

PDFtoPrinter.exe filename.pdf "\\SERVER\PrinterName"

let's say I have a TcpConnection using my local ip of 192.168.0.182. Then if I will like to know the mac address of that NIC I will call the meothod as: GetMacAddressUsedByIp("192.168.0.182")

public static string GetMacAddressUsedByIp(string ipAddress)
    {
        var ips = new List<string>();
        string output;

        try

            // Start the child process.
            Process p = new Process();
            // Redirect the output stream of the child process.
            p.StartInfo.UseShellExecute = false;

            p.StartInfo.RedirectStandardOutput = true;

            // reading to the end of its redirected stream.
            // p.WaitForExit();
            // Read the output stream first and then wait.

As The Tin Man suggests (above) RVM (Ruby Version Manager) is the Standard for upgrading your Ruby installation on OSX: https://rvm.io

To get started, open a Terminal Window and issue the following command:

\curl -L https://get.rvm.io | bash -s stable --ruby

( you will need to trust the RVM Dev Team that the command is not malicious - if you're a paranoid penguin like me, you can always go read the source: https://github.com/wayneeseguin/rvm ) When it's complete you need to restart the terminal to get the rvm command working.

rvm list known

( shows you the latest available versions of Ruby )

rvm install ruby-2.3.1

For a specific version, followed by

rvm use ruby-2.3.1

or if you just want the latest (current) version:

rvm install current && rvm use current

( installs the current stable release - at time of writing ruby-2.3.1 - please update this wiki when new versions released )

Note on Compiling Ruby: In my case I also had to install Homebrew http://mxcl.github.com/homebrew/ to get the gems I needed (RSpec) which in turn forces you to install Xcode (if you haven't already) https://itunes.apple.com/us/app/xcode/id497799835 AND/OR install the GCC package from: https://github.com/kennethreitz/osx-gcc-installer to avoid errors running "make".

Edit: As of Mavericks you can choose to install only the Xcode command line tools instead of the whole Xcode package, which comes with gcc and lots of other things you might need for building packages. It can be installed by running xcode-select --install and following the on-screen prompt.

• Examples: https://rvm.io/workflow/examples/
• Screencast: http://screencasts.org/episodes/how-to-use-rvm

Note on erros: if you get the error "RVM is not a function" while trying this command, visit: How do I change my Ruby version using RVM? for the solution.

Python documentation for sys.exit([arg])says:

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like. Most systems require it to be in the range 0-127, and produce undefined results otherwise.

Moreover to retrieve the return value of the last executed program you could use the $? bash predefined variable.

Anyway if you put a string as arg in sys.exit() it should be printed at the end of your program output in a separate line, so that you can retrieve it just with a little bit of parsing. As an example consider this:

outputString=`python myPythonScript arg1 arg2 arg3 | tail -0`

Your response object is declared as a ServletResponse. To use the sendRedirect() method, you have to cast it to HttpServletResponse. This is an extended interface that adds methods related to the HTTP protocol.

Working with Eclipse can be difficult at times, probably when debugging and designing layouts Eclipse sometimes get stuck and we have to restart Eclipse from time to time. Also you get problems with emulators.

Android studio was released very recently and this IDE is not yet heavily used by developers. Therefore, it may contain certain bugs.

            var filter = /^((\+[1-9]{1,4}[ \-]*)|(\([0-9]{2,3}\)[ \-]*)|([0-9]{2,4})[ \-]*)*?[0-9]{3,4}?[ \-]*[0-9]{3,4}?$/;

            if (filter.test(phoneNumber)) {
              if(phoneNumber.length==10){
                   var validate = true;
              } else {
                  alert('Please put 10  digit mobile number');
                  var validate = false;
              }
            }
            else {
              alert('Not a valid number');
              var validate = false;
            }

         if(validate){
          //number is equal to 10 digit or number is not string 
          enter code here...
        }

If you're posting a json body, dont use the form parameter. Using form will make the arrays into field[0].attribute, field[1].attribute etc. Instead use body like so.

var jsonDataObj = {'mes': 'hey dude', 'yo': ['im here', 'and here']};
request.post({
    url: 'https://api.site.com',
    body: jsonDataObj,
    json: true
  }, function(error, response, body){
  console.log(body);
});

make the checkbox non-focusable, and on list-item click do this, here codevalue is the position.

    Arraylist<Integer> selectedschools=new Arraylist<Integer>();

    lvPickSchool.setOnItemClickListener(new AdapterView.OnItemClickListener() 
  {

   @Override
        public void onItemClick(AdapterView<?> parent, View view, int codevalue, long id)
   {
                      CheckBox cb = (CheckBox) view.findViewById(R.id.cbVisitingStatus);

            cb.setChecked(!cb.isChecked());
            if(cb.isChecked())
            {

                if(!selectedschool.contains(codevaule))
                {
                    selectedschool.add(codevaule);
                }
            }
            else
            {
                if(selectedschool.contains(codevaule))
                {
                    selectedschool.remove(codevaule);
                }
            }
        }
    });

I am using outerHTML for elements (the main <html> container), and XMLSerializer for anything else including <!DOCTYPE>, random comments outside the <html> container, or whatever else might be there. It seems that whitespace isn't preserved outside the <html> element, so I'm adding newlines by default with sep="\n".

function get_document_html(sep="\n") {_x000D_
    let html = "";_x000D_
    let xml = new XMLSerializer();_x000D_
    for (let n of document.childNodes) {_x000D_
        if (n.nodeType == Node.ELEMENT_NODE)_x000D_
            html += n.outerHTML + sep;_x000D_
        else_x000D_
            html += xml.serializeToString(n) + sep;_x000D_
    }_x000D_
    return html;_x000D_
}_x000D_
_x000D_
console.log(get_document_html().slice(0, 200));

It works if id value and name value are different:

<input type="password" class="form-control"name="password" id="mainpassword">
password: {     required: true,     } , 
cpassword: {required: true, equalTo: '#mainpassword' },

I'm showing this for the latest access time, and you can easily modify this to do latest modification time.

There are two ways to do this:

1. If you want to avoid global sorting which can be expensive if you have tens of millions of files, then you can do (position yourself in the root of the directory where you want your search to start):

    Linux> touch -d @0 /tmp/a;
    Linux> find . -type f -exec tcsh -f -c test `stat --printf="%X" {}` -gt  `stat --printf="%X" /tmp/a`  ; -exec tcsh -f -c touch -a -r {} /tmp/a ; -print
   

   The above method prints filenames with progressively newer access time and the last file it prints is the file with the latest access time. You can obviously get the latest access time using a "tail -1".

2. You can have find recursively print the name and access time of all files in your subdirectory and then sort based on access time and the tail the biggest entry:

    Linux> \find . -type f -exec stat --printf="%X  %n\n" {} \; | \sort -n | tail -1
   

And there you have it...

It is because you forgot to pass in event into the click function:

$('.menuOption').on('click', function (e) { // <-- the "e" for event

    e.preventDefault(); // now it'll work

    var categories = $(this).attr('rel');
    $('.pages').hide();
    $(categories).fadeIn();
});

On a side note, e is more commonly used as opposed to the word event since Event is a global variable in most browsers.

It should be understood that from a performance standpoint there are no differences between @temp tables and #temp tables that favor variables. They reside in the same place (tempdb) and are implemented the same way. All the differences appear in additional features. See this amazingly complete writeup: https://dba.stackexchange.com/questions/16385/whats-the-difference-between-a-temp-table-and-table-variable-in-sql-server/16386#16386

Although there are cases where a temp table can't be used such as in table or scalar functions, for most other cases prior to v2016 (where even filtered indexes can be added to a table variable) you can simply use a #temp table.

The drawback to using named indexes (or constraints) in tempdb is that the names can then clash. Not just theoretically with other procedures but often quite easily with other instances of the procedure itself which would try to put the same index on its copy of the #temp table.

To avoid name clashes, something like this usually works:

declare @cmd varchar(500)='CREATE NONCLUSTERED INDEX [ix_temp'+cast(newid() as varchar(40))+'] ON #temp (NonUniqueIndexNeeded);';
exec (@cmd);

This insures the name is always unique even between simultaneous executions of the same procedure.

DBMS_OUTPUT is not the best tool to debug, since most environments don't use it natively. If you want to capture the output of DBMS_OUTPUT however, you would simply use the DBMS_OUTPUT.get_line procedure.

Here is a small example:

SQL> create directory tmp as '/tmp/';

Directory created

SQL> CREATE OR REPLACE PROCEDURE write_log AS
  2     l_line VARCHAR2(255);
  3     l_done NUMBER;

  6     l_file := utl_file.fopen('TMP', 'foo.log', 'A');
  7     LOOP
  8        EXIT WHEN l_done = 1;
  9        dbms_output.get_line(l_line, l_done);
 10        utl_file.put_line(l_file, l_line);
 11     END LOOP;
 12     utl_file.fflush(l_file);
 13     utl_file.fclose(l_file);
 14  END write_log;
 15  /

  6     write_log;

For me, i had to uninstall R from brew brew uninstall --force R and then head over to the R website and download and install it from there.

probably graded as a non-pythonic way to do this but this'll give the result you want in a line:

new_df = pd.DataFrame(zip(email,list))

Result:

               email               list
0   [email protected]    [1.0, 0.0, 0.0]
1   [email protected]    [2.0, 0.0, 0.0]
2   [email protected]    [1.0, 0.0, 0.0]
3   [email protected]    [4.0, 0.0, 3.0]
4   [email protected]    [1.0, 5.0, 0.0]

On your Player class, implement the following two methods (substituting calls to encodeObject with something relevant to your own object):

- (void)encodeWithCoder:(NSCoder *)encoder {
    //Encode properties, other class variables, etc
    [encoder encodeObject:self.question forKey:@"question"];
    [encoder encodeObject:self.categoryName forKey:@"category"];
    [encoder encodeObject:self.subCategoryName forKey:@"subcategory"];
}

- (id)initWithCoder:(NSCoder *)decoder {
    if((self = [super init])) {
        //decode properties, other class vars
        self.question = [decoder decodeObjectForKey:@"question"];
        self.categoryName = [decoder decodeObjectForKey:@"category"];
        self.subCategoryName = [decoder decodeObjectForKey:@"subcategory"];
    }
    return self;
}

Reading and writing from NSUserDefaults:

- (void)saveCustomObject:(MyObject *)object key:(NSString *)key {
    NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:encodedObject forKey:key];
    [defaults synchronize];

}

- (MyObject *)loadCustomObjectWithKey:(NSString *)key {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSData *encodedObject = [defaults objectForKey:key];
    MyObject *object = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];
    return object;
}

Code shamelessly borrowed from: saving class in nsuserdefaults

$("input[name='bla[]']").each( function () {
    alert($(this).val());
});

As mentioned in the other comment, the transform attribute on the g element is what you want. Use transform="translate(x,y)" to move the g around and things within the g will move in relation to the g.

Use string concatenation:

href={'/posts/' + post.id}

The JSX syntax allows either to use strings or expressions ({...}) as values. You cannot mix both. Inside an expression you can, as the name suggests, use any JavaScript expression to compute the value.

Another way is using a ResourceBundle. Basically you get the bundle using its name without the '.properties'

private static final ResourceBundle resource = ResourceBundle.getBundle("config");

And you recover any value using this:

private final String prop = resource.getString("propName");

oops! just found myself: just add this line on any element you need

   -webkit-appearance: none;

Content inside a <div class='html-content'>....</div> can be downloaded as pdf with styles using jspdf & html2canvas.

You need to refer both js libraries,

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.min.js"></script>
<script type="text/javascript" src="https://html2canvas.hertzen.com/dist/html2canvas.js"></script>

Then call below function,

//Create PDf from HTML...
function CreatePDFfromHTML() {
    var HTML_Width = $(".html-content").width();
    var HTML_Height = $(".html-content").height();
    var top_left_margin = 15;
    var PDF_Width = HTML_Width + (top_left_margin * 2);
    var PDF_Height = (PDF_Width * 1.5) + (top_left_margin * 2);
    var canvas_image_width = HTML_Width;
    var canvas_image_height = HTML_Height;

    var totalPDFPages = Math.ceil(HTML_Height / PDF_Height) - 1;

    html2canvas($(".html-content")[0]).then(function (canvas) {
        var imgData = canvas.toDataURL("image/jpeg", 1.0);
        var pdf = new jsPDF('p', 'pt', [PDF_Width, PDF_Height]);
        pdf.addImage(imgData, 'JPG', top_left_margin, top_left_margin, canvas_image_width, canvas_image_height);
        for (var i = 1; i <= totalPDFPages; i++) { 
            pdf.addPage(PDF_Width, PDF_Height);
            pdf.addImage(imgData, 'JPG', top_left_margin, -(PDF_Height*i)+(top_left_margin*4),canvas_image_width,canvas_image_height);
        }
        pdf.save("Your_PDF_Name.pdf");
        $(".html-content").hide();
    });
}

May be this will help someone.

When you want to use a transcompiler, then you could give TypeScript a try. It supports draft ECMA features (in the proposal, interfaces are called "protocols") similar to what languages like coffeescript or babel do.

In TypeScript your interface can look like:

interface IMyInterface {
    id: number; // TypeScript types are lowercase
    name: string;
    callback: (key: string; value: any; array: string[]) => void;
    type: "test" | "notATest"; // so called "union type"
}

What you can't do:

• Define RegExp patterns for type value
• Define validation like string length
• Number ranges
• etc.

For newer versions of sdk you have to set flag activity task.

public void onClick(View v)
 {
     Intent myactivity = new Intent(context.getApplicationContext(), OtherActivity.class);
     myactivity.addFlags(FLAG_ACTIVITY_NEW_TASK);
     context.getApplicationContext().startActivity(myactivity);
 }

Thank you for your responses. Turns out my problem was a database issue with duplicate entries, not with my logic. A quick table sync fixed that and the SUM feature worked as expected. This is all still useful knowledge for the SUM feature and is worth reading if you are having trouble using it.

I know this is a bit old but the answer in short would be <load-on-startup> both occurrences have given the same id which is 1 twice. This may confuse loading sequence.

Use this if you also want to consider non-javascript users:

echo ("<SCRIPT LANGUAGE='JavaScript'>
           window.alert('Succesfully Updated')
           window.location.href='http://someplace.com';
       </SCRIPT>
       <NOSCRIPT>
           <a href='http://someplace.com'>Successfully Updated. Click here if you are not redirected.</a>
       </NOSCRIPT>");

    ClassLoader cl = ClassLoader.getSystemClassLoader();

    URL[] urls = ((URLClassLoader)cl).getURLs();

    for(URL url: urls){
        System.out.println(url.getFile());
    }

I couln't find the SOAP section in phpinfo() so I had to install it.

For information the SOAP extension requires the libxml PHP extension. This means that passing in --enable-libxml is also required according to http://php.net/manual/en/soap.requirements.php

From WHM panel

1. Software » Module Installers » PHP Extensions & Applications Package

2. Install SOAP 0.13.0

   WARNING: "pear/HTTP_Request" is deprecated in favor of "pear/HTTP_Request2"

   install ok: channel://pear.php.net/SOAP-0.13.0

3. Install HTTP_Request2 (optional)

   install ok: channel://pear.php.net/HTTP_Request2

4. Restart Services » HTTP Server (Apache)

From shell command

1.pear install SOAP

2.reboot

For SQL server 2000:

     INSERT INTO t1 (ID, NAME)
      SELECT valueid, valuename
      WHERE  NOT EXISTS
               (SELECT 0
                FROM   t1 as t2
                WHERE  t2.ID = valueid AND t2.name = valuename)

In case anyone was wondering - it was probably my css...

@font-face
  font-family: "bingo"
  src: url('bingo.eot')
  src: local('bingo')
  src: url('bingo.svg#bingo') format('svg')
  src: url('bingo.otf') format('opentype')

will render as

@font-face {
  font-family: "bingo";
  src: url('bingo.eot');
  src: local('bingo');
  src: url('bingo.svg#bingo') format('svg');
  src: url('bingo.otf') format('opentype'); }

which seems to be close enough... just need to check the SVG rendering

If you know the list of ids try this query:

SELECT * FROM `Buses` WHERE BusId IN (`list of busIds`)

or if you pull them from another table list of busIds could be another subquery:

SELECT * FROM `Buses` WHERE BusId IN (SELECT SomeId from OtherTable WHERE something = somethingElse)

If you need to compare to another table you need a join:

SELECT * FROM `Buses` JOIN OtheTable on Buses.BusesId = OtehrTable.BusesId

It's simple...

=CONCATENATE(A1, ",")

Example: if [email protected] is in the A1 cell then write in another cell: =CONCATENATE(A1, ",")

[email protected] After this formula you will get [email protected],

For remove formula: copy that cell and use Alt + E + S + V or paste special value.

It's important to have clear definitions of what terms mean. Unfortunately there appears to be multiple definitions of what static and dynamic arrays mean.

Static variables are variables defined using static memory allocation. This is a general concept independent of C/C++. In C/C++ we can create static variables with global, file, or local scope like this:

int x[10]; //static array with global scope
static int y[10]; //static array with file scope
foo() {
    static int z[10]; //static array with local scope

Automatic variables are usually implemented using stack-based memory allocation. An automatic array can be created in C/C++ like this:

foo() {
    int w[10]; //automatic array

What these arrays , x, y, z, and w have in common is that the size for each of them is fixed and is defined at compile time.

One of the reasons that it's important to understand the distinction between an automatic array and a static array is that static storage is usually implemented in the data section (or BSS section) of an object file and the compiler can use absolute addresses to access the arrays which is impossible with stack-based storage.

What's usually meant by a dynamic array is not one that is resizeable but one implemented using dynamic memory allocation with a fixed size determined at run-time. In C++ this is done using the new operator.

foo() {
   int *d = new int[n]; //dynamically allocated array with size n     

But it's possible to create an automatic array with a fixes size defined at runtime using alloca:

foo() {
    int *s = (int*)alloca(n*sizeof(int))

For a true dynamic array one should use something like std::vector in C++ (or a variable length array in C).

What was meant for the assignment in the OP's question? I think it's clear that what was wanted was not a static or automatic array but one that either used dynamic memory allocation using the new operator or a non-fixed sized array using e.g. std::vector.

This is a limitation of XmlSerializer. Note that BinaryFormatter and DataContractSerializer do not require this - they can create an uninitialized object out of the ether and initialize it during deserialization.

Since you are using xml, you might consider using DataContractSerializer and marking your class with [DataContract]/[DataMember], but note that this changes the schema (for example, there is no equivalent of [XmlAttribute] - everything becomes elements).

Update: if you really want to know, BinaryFormatter et al use FormatterServices.GetUninitializedObject() to create the object without invoking the constructor. Probably dangerous; I don't recommend using it too often ;-p See also the remarks on MSDN:

Because the new instance of the object is initialized to zero and no constructors are run, the object might not represent a state that is regarded as valid by that object. The current method should only be used for deserialization when the user intends to immediately populate all fields. It does not create an uninitialized string, since creating an empty instance of an immutable type serves no purpose.

I have my own serialization engine, but I don't intend making it use FormatterServices; I quite like knowing that a constructor (any constructor) has actually executed.

I use this code to daemonize my applications. It allows you start/stop/restart the script using the following commands.

python myscript.py start
python myscript.py stop
python myscript.py restart

In addition to this I also have an init.d script for controlling my service. This allows you to automatically start the service when your operating system boots-up.

Here is a simple example to get your going. Simply move your code inside a class, and call it from the run function inside MyDeamon.

import sys
import time

from daemon import Daemon


class YourCode(object):
    def run(self):
        while True:
            time.sleep(1)


class MyDaemon(Daemon):
    def run(self):
        # Or simply merge your code with MyDaemon.
        your_code = YourCode()
        your_code.run()


if __name__ == "__main__":
    daemon = MyDaemon('/tmp/daemon-example.pid')
    if len(sys.argv) == 2:
        if 'start' == sys.argv[1]:
            daemon.start()
        elif 'stop' == sys.argv[1]:
            daemon.stop()
        elif 'restart' == sys.argv[1]:
            daemon.restart()
        else:
            print "Unknown command"
            sys.exit(2)
        sys.exit(0)
    else:
        print "usage: %s start|stop|restart" % sys.argv[0]
        sys.exit(2)

Upstart

If you are running an operating system that is using Upstart (e.g. CentOS 6) - you can also use Upstart to manage the service. If you use Upstart you can keep your script as is, and simply add something like this under /etc/init/my-service.conf

start on started sshd
stop on runlevel [!2345]

exec /usr/bin/python /opt/my_service.py
respawn

You can then use start/stop/restart to manage your service.

e.g.

start my-service
stop my-service
restart my-service

A more detailed example of working with upstart is available here.

Systemd

If you are running an operating system that uses Systemd (e.g. CentOS 7) you can take a look at the following Stackoverflow answer.

This can occur when you are showing the dialog for a context that no longer exists. A common case - if the 'show dialog' operation is after an asynchronous operation, and during that operation the original activity (that is to be the parent of your dialog) is destroyed. For a good description, see this blog post and comments:

http://dimitar.me/android-displaying-dialogs-from-background-threads/

From the stack trace above, it appears that the facebook library spins off the auth operation asynchronously, and you have a Handler - Callback mechanism (onComplete called on a listener) that could easily create this scenario.

When I've seen this reported in my app, its pretty rare and matches the experience in the blog post. Something went wrong for the activity/it was destroyed during the work of the the AsyncTask. I don't know how your modification could result in this every time, but perhaps you are referencing an Activity as the context for the dialog that is always destroyed by the time your code executes?

Also, while I'm not sure if this is the best way to tell if your activity is running, see this answer for one method of doing so:

Check whether activity is active

Try this:

• Tested in Angular 8
• values are positive
• This code also handels null and negitive values.

              <input
                type="number"
                min="0"
                (input)="funcCall()" -- Optional
                oninput="value == '' ? value = 0 : value < 0 ? value = value * -1 : false"
                formControlName="RateQty"
                [(value)]="some.variable" -- Optional
              />

getName() – returns the name of the entity (class, interface, array class, primitive type, or void) represented by this Class object, as a String.

getCanonicalName() – returns the canonical name of the underlying class as defined by the Java Language Specification.

getSimpleName() – returns the simple name of the underlying class, that is the name it has been given in the source code.

package com.practice;

public class ClassName {
public static void main(String[] args) {

  ClassName c = new ClassName();
  Class cls = c.getClass();

  // returns the canonical name of the underlying class if it exists
  System.out.println("Class = " + cls.getCanonicalName());    //Class = com.practice.ClassName
  System.out.println("Class = " + cls.getName());             //Class = com.practice.ClassName
  System.out.println("Class = " + cls.getSimpleName());       //Class = ClassName
  System.out.println("Class = " + Map.Entry.class.getName());             // -> Class = java.util.Map$Entry
  System.out.println("Class = " + Map.Entry.class.getCanonicalName());    // -> Class = java.util.Map.Entry
  System.out.println("Class = " + Map.Entry.class.getSimpleName());       // -> Class = Entry 
  }
}

One difference is that if you use an anonymous class you can get a null value when trying to get the name of the class using the getCanonicalName()

Another fact is that getName() method behaves differently than the getCanonicalName() method for inner classes. getName() uses a dollar as the separator between the enclosing class canonical name and the inner class simple name.

To know more about retrieving a class name in Java.

Well, the easiest solution would of course be to pipe the output into mail:

vs@lambda:~$ cat test.sh
sleep 3 && echo test | mail -s test your@address
vs@lambda:~$ nohup sh test.sh
nohup: ignoring input and appending output to `nohup.out'

I guess sh test.sh & will do just as fine normally.

The original code works fine for reading and separating the csv file data but you need to change the data type from csv to text.

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/

For the first one: your program will go through the loop once for every row in the result set returned by the query. You can know in advance how many results there are by using mysql_num_rows().

For the second one: this time you are only using one row of the result set and you are doing something for each of the columns. That's what the foreach language construct does: it goes through the body of the loop for each entry in the array $row. The number of times the program will go through the loop is knowable in advance: it will go through once for every column in the result set (which presumably you know, but if you need to determine it you can use count($row)).

This error is cause by security clutches between the web application and your java. To resolve it, look into your java setting under control panel. Move the security level to a medium.

It appears to me that you have two issues here. One is that JFrame does not have a close method, which has been addressed in the other answers.

The other is that you're having trouble referencing your JFrame. Within actionPerformed, super refers to ActionListener. To refer to the JFrame instance there, use MyExtendedJFrame.super instead (you should also be able to use MyExtendedJFrame.this, as I see no reason why you'd want to override the behaviour of dispose or setVisible).

Actually, if you don't know if the subfolders have a git repo or not, the best would be to let find get the repos for you:

find . -type d -name .git -exec git --git-dir={} --work-tree=$PWD/{}/.. pull origin master \;

The PowerShell equivalent would be:

Get-ChildItem -Recurse -Directory -Hidden  -Filter .git | ForEach-Object { & git --git-dir="$($_.FullName)" --work-tree="$(Split-Path $_.FullName -Parent)" pull origin master }

Adding MaxHeight and VerticalScrollBarVisibility="Auto" on the DataGrid solved my problem.

You can use the function stat.desc from pastec package.

library(pastec)
stat.desc(x, BASIC =TRUE, NORMAL =TRUE)

you can find more about it from here: https://www.rdocumentation.org/packages/pastecs/versions/1.3.21/topics/stat.desc

If using MS Visual C++ 10.0, you can do this with standard library facilities:

Concurrency::wait(milliseconds);

you will need:

#include <concrt.h>

Simple and effective.

Eslint 6.7.0 brought "ignorePatterns" to write it in .eslintrc.json like this example:

    "ignorePatterns": ["fileToBeIgnored.js"],
    "rules": {

    }
}

This solution works for matplotlib versions 3.0.1, 3.0.3 and 3.2.1.

def save_inp_as_output(_img, c_name, dpi=100):
    h, w, _ = _img.shape
    fig, axes = plt.subplots(figsize=(h/dpi, w/dpi))
    fig.subplots_adjust(top=1.0, bottom=0, right=1.0, left=0, hspace=0, wspace=0) 
    axes.imshow(_img)
    axes.axis('off')
    plt.savefig(c_name, dpi=dpi, format='jpeg') 

Because the subplots_adjust setting makes the axis fill the figure, you don't want to specify a bbox_inches='tight', as it actually creates whitespace padding in this case. This solution works when you have more than 1 subplot also.

For those who have problems with IE and for others too.

{
    float: left;
    width: 1px;
    height: 1px;
    background-color: transparent;
    border: none;
}

You need something like this:

foreach(DataColumn c in dr.Table.Columns)
{
  MessageBox.Show(c.ColumnName);
}

(1) Set the tabindex attribute:

<div id="mydiv" tabindex="0" />

(2) Bind to keydown:

 $('#mydiv').on('keydown', function(event) {
    //console.log(event.keyCode);
    switch(event.keyCode){
       //....your actions for the keys .....
    }
 });

To set the focus on start:

$(function() {
   $('#mydiv').focus();
});

To remove - if you don't like it - the div focus border, set outline: none in the CSS.

See the table of keycodes for more keyCode possibilities.

All of the code assuming you use jQuery.

I was running into the exact same problem that Saurav described, but I really needed to find a solution that did not require anything other than Route 53 and S3. I created a how-to guide for my blog detailing what I did.

Here is what I came up with.

Objective

Using only the tools available in Amazon S3 and Amazon Route 53, create a URL Redirect that automatically forwards http://url-redirect-example.vivekmchawla.com to the AWS Console sign-in page aliased to "MyAccount", located at https://myaccount.signin.aws.amazon.com/console/ .

This guide will teach you set up URL forwarding to any URL, not just ones from Amazon. You will learn how to set up forwarding to specific folders (like "/console" in my example), and how to change the protocol of the redirect from HTTP to HTTPS (or vice versa).

Step One: Create Your S3 Bucket

Open the S3 management console and click "Create Bucket".

Step Two: Name Your S3 Bucket

1. Choose a Bucket Name. This step is really important! You must name the bucket EXACTLY the same as the URL you want to set up for forwarding. For this guide, I'll use the name "url-redirect-example.vivekmchawla.com".

2. Select whatever region works best for you. If you don't know, keep the default.

3. Don't worry about setting up logging. Just click the "Create" button when you're ready.

Step 3: Enable Static Website Hosting and Specify Routing Rules

1. In the properties window, open the settings for "Static Website Hosting".
2. Select the option to "Enable website hosting".
3. Enter a value for the "Index Document". This object (document) will never be served by S3, and you never have to upload it. Just use any name you want.
4. Open the settings for "Edit Redirection Rules".

5. Paste the following XML snippet in it's entirety.

   <RoutingRules>
     <RoutingRule>
       <Redirect>
         <Protocol>https</Protocol>
         <HostName>myaccount.signin.aws.amazon.com</HostName>
         <ReplaceKeyPrefixWith>console/</ReplaceKeyPrefixWith>
         <HttpRedirectCode>301</HttpRedirectCode>
       </Redirect>
     </RoutingRule>
   </RoutingRules>
   

If you're curious about what the above XML is doing, visit the AWM Documentation for "Syntax for Specifying Routing Rules". A bonus technique (not covered here) is forwarding to specific pages at the destination host, for example http://redirect-destination.com/console/special-page.html. Read about the <ReplaceKeyWith> element if you need this functionality.

Step 4: Make Note of Your Redirect Bucket's "Endpoint"

Make note of the Static Website Hosting "endpoint" that Amazon automatically created for this bucket. You'll need this for later, so highlight the entire URL, then copy and paste it to notepad.

CAUTION! At this point you can actually click this link to check to see if your Redirection Rules were entered correctly, but be careful! Here's why...

Let's say you entered the wrong value inside the <Hostname> tags in your Redirection Rules. Maybe you accidentally typed myaccount.amazon.com, instead of myaccount.signin.aws.amazon.com. If you click the link to test the Endpoint URL, AWS will happily redirect your browser to the wrong address!

After noticing your mistake, you will probably edit the <Hostname> in your Redirection Rules to fix the error. Unfortunately, when you try to click the link again, you'll most likely end up being redirected back to the wrong address! Even though you fixed the <Hostname> entry, your browser is caching the previous (incorrect!) entry. This happens because we're using an HTTP 301 (permanent) redirect, which browsers like Chrome and Firefox will cache by default.

If you copy and paste the Endpoint URL to a different browser (or clear the cache in your current one), you'll get another chance to see if your updated <Hostname> entry is finally the correct one.

To be safe, if you want to test your Endpoint URL and Redirect Rules, you should open a private browsing session, like "Incognito Mode" in Chrome. Copy, paste, and test the Endpoint URL in Incognito Mode and anything cached will go away once you close the session.

Step 5: Open the Route53 Management Console and Go To the Record Sets for Your Hosted Zone (Domain Name)

1. Select the Hosted Zone (domain name) that you used when you created your bucket. Since I named my bucket "url-redirect-example.vivekmchawla.com", I'm going to select the vivekmchawla.com Hosted Zone.
2. Click on the "Go to Record Sets" button.

Step 6: Click the "Create Record Set" Button

Clicking "Create Record Set" will open up the Create Record Set window on the right side of the Route53 Management Console.

Step 7: Create a CNAME Record Set

1. In the Name field, enter the hostname portion of the URL that you used when naming your S3 bucket. The "hostname portion" of the URL is everything to the LEFT of your Hosted Zone's name. I named my S3 bucket "url-redirect-example.vivekmchawla.com", and my Hosted Zone is "vivekmchawla.com", so the hostname portion I need to enter is "url-redirect-example".

2. Select "CNAME - Canonical name" for the Type of this Record Set.

3. For the Value, paste in the Endpoint URL of the S3 bucket we created back in Step 3.

4. Click the "Create Record Set" button. Assuming there are no errors, you'll now be able to see a new CNAME record in your Hosted Zone's list of Record Sets.

Step 8: Test Your New URL Redirect

Open up a new browser tab and type in the URL that we just set up. For me, that's http://url-redirect-example.vivekmchawla.com. If everything worked right, you should be sent directly to an AWS sign-in page.

Because we used the myaccount.signin.aws.amazon.com alias as our redirect's destination URL, Amazon knows exactly which account we're trying to access, and takes us directly there. This can be very handy if you want to give a short, clean, branded AWS login link to employees or contractors.

Conclusions

I personally love the various AWS services, but if you've decided to migrate DNS management to Amazon Route 53, the lack of easy URL forwarding can be frustrating. I hope this guide helped make setting up URL forwarding for your Hosted Zones a bit easier.

If you'd like to learn more, please take a look at the following pages from the AWS Documentation site.

Taken from the latest stable Oracle production version 12.2: Data Types

The major difference is that VARCHAR2 is an internal data type and VARCHAR is an external data type. So we need to understand the difference between an internal and external data type...

Inside a database, values are stored in columns in tables. Internally, Oracle represents data in particular formats known as internal data types.

In general, OCI (Oracle Call Interface) applications do not work with internal data type representations of data, but with host language data types that are predefined by the language in which they are written. When data is transferred between an OCI client application and a database table, the OCI libraries convert the data between internal data types and external data types.

External types provide a convenience for the programmer by making it possible to work with host language types instead of proprietary data formats. OCI can perform a wide range of data type conversions when transferring data between an Oracle database and an OCI application. There are more OCI external data types than Oracle internal data types.

The VARCHAR2 data type is a variable-length string of characters with a maximum length of 4000 bytes. If the init.ora parameter max_string_size is default, the maximum length of a VARCHAR2 can be 4000 bytes. If the init.ora parameter max_string_size = extended, the maximum length of a VARCHAR2 can be 32767 bytes

The VARCHAR data type stores character strings of varying length. The first 2 bytes contain the length of the character string, and the remaining bytes contain the string. The specified length of the string in a bind or a define call must include the two length bytes, so the largest VARCHAR string that can be received or sent is 65533 bytes long, not 65535.

A quick test in a 12.2 database suggests that as an internal data type, Oracle still treats a VARCHAR as a pseudotype for VARCHAR2. It is NOT a SYNONYM which is an actual object type in Oracle.

SQL> select substr(banner,1,80) from v$version where rownum=1;
Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production    

SQL> create table test (my_char varchar(20));
Table created.

SQL> desc test
Name                 Null?    Type
MY_CHAR                       VARCHAR2(20)

There are also some implications of VARCHAR for ProC/C++ Precompiler options. For programmers who are interested, the link is at: Pro*C/C++ Programmer's Guide

The following library can also be used for HTML escaping in Java: unbescape.

HTML can be unescaped this way:

final String unescapedText = HtmlEscape.unescapeHtml(escapedText); 

Since strings are immutable, both versions are safe. The latter, however, is less efficient (it creates an extra object and in some cases copies the character data).

With this in mind, the first version should be preferred.

#if defined(CONDITION1) || defined(CONDITION2)

should work. :)

#ifdef is a bit less typing, but doesn't work well with more complex conditions

List comprehension can shorten things...

win_percentages = [m**2.0 / (m**2.0 + n**2.0) * 100 for m, n in [a[i] for i in NL_East]]

While you can't yet get Firefox to remove the dropdown arrow (see MatTheCat's post), you can hide your "stylized" background image from showing in Firefox.

-moz-background-position: -9999px -9999px!important;

This will position it out of frame, leaving you with the default select box arrow – while keeping the stylized version in Webkit.

You could use RegEx:

Regex.IsMatch(hello, @"^[a-zA-Z]+$");

If you don't like that, you can use LINQ:

hello.All(Char.IsLetter);

Or, you can loop through the characters, and use isAlpha:

Char.IsLetter(character);

You can get any part of the file path using the FileSystemObject. GetFileName(filepath) gives you what you want.

Modified code below:

Sub GetFilePath()
Dim objFSO as New FileSystemObject

Set myFile = Application.FileDialog(msoFileDialogOpen)
With myFile
.Title = "Choose File"
.AllowMultiSelect = False
If .Show <> -1 Then
Exit Sub
End If
FileSelected = .SelectedItems(1)
End With

ActiveSheet.Range("A1") = FileSelected 'The file path
ActiveSheet.Range("A2") = objFSO.GetFileName(FileSelected) 'The file name
End Sub

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

I don't think this is possible using PostgreSQL alone in the most general case. When you install PostgreSQL, you pick a time zone. I'm pretty sure the default is to use the operating system's timezone. That will usually be reflected in postgresql.conf as the value of the parameter "timezone". But the value ends up as "localtime". You can see this setting with the SQL statement.

show timezone;

But if you change the timezone in postgresql.conf to something like "Europe/Berlin", then show timezone; will return that value instead of "localtime".

So I think your solution will involve setting "timezone" in postgresql.conf to an explicit value rather than the default "localtime".

You can also put multi-line comments using:

: '
comment1comment1
comment2comment2
comment3comment3
comment4comment4
'

As per the Bash Reference for Bourne Shell builtins

: (a colon)

: [arguments]

Do nothing beyond expanding arguments and performing redirections. The return status is zero.

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

Vagrant-lxc is a plugin for Vagrant that let's you use LXC to provision Vagrant. It does not have all the features that the default vagrant VM (VirtualBox) has but it should allow you more flexibility than docker containers.

You can parse the string using Html Agility pack and get the InnerText.

    HtmlDocument htmlDoc = new HtmlDocument();
    htmlDoc.LoadHtml(@"<b> Hulk Hogan's Celebrity Championship Wrestling &nbsp;&nbsp;&nbsp;<font color=\"#228b22\">[Proj # 206010]</font></b>&nbsp;&nbsp;&nbsp; (Reality Series, &nbsp;)");

You mean:

Wscript.Echo "Like this?"

If you run that under wscript.exe (the default handler for the .vbs extension, so what you'll get if you double-click the script) you'll get a "MessageBox" dialog with your text in it. If you run that under cscript.exe you'll get output in your console window.

Actually, there is some possibility to send a table data from one PostgreSQL database to another. I use the procedural language plperlu (unsafe Perl procedural language) for it.

Description (all was done on a Linux server):

1. Create plperlu language in your database A

2. Then PostgreSQL can join some Perl modules through series of the following commands at the end of postgresql.conf for the database A:

   plperl.on_init='use DBI;'
   plperl.on_init='use DBD::Pg;'
   

3. You build a function in A like this:

   CREATE OR REPLACE FUNCTION send_data( VARCHAR )
   RETURNS character varying AS
   $BODY$
   my $command = $_[0] || die 'No SQL command!';
   my $connection_string =
   "dbi:Pg:dbname=your_dbase;host=192.168.1.2;port=5432;";
   $dbh = DBI->connect($connection_string,'user','pass',

   my $sql = $dbh-> prepare( $command );

And then you can call the function inside database A:

SELECT send_data( 'INSERT INTO jm (jm) VALUES (''zzzzzz'')' );

And the value "zzzzzz" will be added into table "jm" in database B.

On saveAndFlush, changes will be flushed to DB immediately in this command. With save, this is not necessarily true, and might stay just in memory, until flush or commit commands are issued.

But be aware, that even if you flush the changes in transaction and do not commit them, the changes still won't be visible to the outside transactions until the commit in this transaction.

In your case, you probably use some sort of transactions mechanism, which issues commit command for you if everything works out fine.

this.setState creates an infinite loop when used in ComponentDidUpdate when there is no break condition in the loop. You can use redux to set a variable true in the if statement and then in the condition set the variable false then it will work.

Something like this.

if(this.props.route.params.resetFields){

        this.props.route.params.resetFields = false;
        this.setState({broadcastMembersCount: 0,isLinkAttached: false,attachedAffiliatedLink:false,affilatedText: 'add your affiliate link'});
        this.resetSelectedContactAndGroups();
        this.hideNext = false;
        this.initialValue_1 = 140;
        this.initialValue_2 = 140;
        this.height = 20
    }

I had the same problem with Visual Studio 2015 and Resharper 9.2

"Resharper 9 keyboard shortcuts not working in Visual Studio 2015"

I had tried all possible resetting and applying keyboard schemes and found the answer from Yuri Fedoseev.

My Windows 10 language configuration only had Swedish in the language preferences "Control Panel\Clock, Language, and Region\Language"

The solution was to add English(I chose the US version) in the language list. And then go to Resharper > Options > Keyboard & Menus > Apply Scheme. (perhaps you do not even need to apply the scheme)

This should unstage a <file> for you (without removing or otherwise modifying the file):

git reset <file>

If you are using jQuery in your project, or are willing to include it you can call nth-last-child through its selector API (this is this simulated it will cross browser). Here is a link to an nth-last-child plugin. If you took this method of targeting the elements you were interested in:

$('ul li:nth-last-child(1)').addClass('last');

And then style again the last class instead of the nth-child or nth-last-child pseudo selectors, you will have a much more consistent cross browser experience.

The article links to the gulpfile on GitHub where he's implemented the strategy in the article. You could just copy and paste most of the gulpfile contents into yours, but be sure to add the appropriate packages in package.json under devDependencies: gulp gulp-uglify gulp-concat rimraf merge-stream

While in insert mode, you can use Ctrl-R {register}, where register can be:

• + for the clipboard,
• * for the X clipboard (last selected text in X),
• " for the unnamed register (last delete or yank in Vim),
• or a number of others (see :h registers).

Ctrl-R {register} inserts the text as if it were typed.

Ctrl-R Ctrl-O {register} inserts the text with the original indentation.

Ctrl-R Ctrl-P {register} inserts the text and auto-indents it.

Ctrl-O can be used to run any normal mode command before returning to insert mode, so
Ctrl-O "+p can also be used, for example.

For more information, view the documentation with :h i_ctrl-r

According to the Python 2 Glossary, iterables are

all sequence types (such as list, str, and tuple) and some non-sequence types like dict and file and objects of any classes you define with an __iter__() or __getitem__() method. Iterables can be used in a for loop and in many other places where a sequence is needed (zip(), map(), ...). When an iterable object is passed as an argument to the built-in function iter(), it returns an iterator for the object.

Of course, given the general coding style for Python based on the fact that it's “Easier to ask for forgiveness than permission.”, the general expectation is to use

try:
    for i in object_in_question:
        do_something
except TypeError:
    do_something_for_non_iterable

But if you need to check it explicitly, you can test for an iterable by hasattr(object_in_question, "__iter__") or hasattr(object_in_question, "__getitem__"). You need to check for both, because strs don't have an __iter__ method (at least not in Python 2, in Python 3 they do) and because generator objects don't have a __getitem__ method.

  public  boolean isInternetConnection()

                connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED) {
            //we are connected to a network
            return  true;
        }
        else {
            return false;
        }
    }

public static int factorial(int n)
{
    if(n == 1)
    {
        return 1;
    }               
    return n * factorial(n-1);
}

with while loop:

public static int factorial1(int n)
{
    int fact=1;
    while(n>=1)
    {
        fact=fact*n;
        n--;

    return fact;
}

TLDR; MySql does not have an equivalent concept of varchar(max), this is a MS SQL Server feature.

What is VARCHAR(max)?

varchar(max) is a feature of Microsoft SQL Server.

The amount of data that a column could store in Microsoft SQL server versions prior to version 2005 was limited to 8KB. In order to store more than 8KB you would have to use TEXT, NTEXT, or BLOB columns types, these column types stored their data as a collection of 8K pages separate from the table data pages; they supported storing up to 2GB per row.

The big caveat to these column types was that they usually required special functions and statements to access and modify the data (e.g. READTEXT, WRITETEXT, and UPDATETEXT)

In SQL Server 2005, varchar(max) was introduced to unify the data and queries used to retrieve and modify data in large columns. The data for varchar(max) columns is stored inline with the table data pages.

As the data in the MAX column fills an 8KB data page an overflow page is allocated and the previous page points to it forming a linked list. Unlike TEXT, NTEXT, and BLOB the varchar(max) column type supports all the same query semantics as other column types.

So varchar(MAX) really means varchar(AS_MUCH_AS_I_WANT_TO_STUFF_IN_HERE_JUST_KEEP_GROWING) and not varchar(MAX_SIZE_OF_A_COLUMN).

MySql does not have an equivalent idiom.

In order to get the same amount of storage as a varchar(max) in MySql you would still need to resort to a BLOB column type. This article discusses a very effective method of storing large amounts of data in MySql efficiently.

The simple answer is to use the HttpRequest.UserHostAddress property.

Example: From within a Controller:

using System;
using System.Web.Mvc;

namespace Mvc.Controllers
{
    public class HomeController : ClientController
    {
        public ActionResult Index()
        {
            string ip = Request.UserHostAddress;

            ...
        }
    }
}

Example: From within a helper class:

using System.Web;

namespace Mvc.Helpers
{
    public static class HelperClass
    {
        public static string GetIPHelper()
        {
            string ip = HttpContext.Current.Request.UserHostAddress;
            ..
        }
    }
}

BUT, if the request has been passed on by one, or more, proxy servers then the IP address returned by HttpRequest.UserHostAddress property will be the IP address of the last proxy server that relayed the request.

Proxy servers MAY use the de facto standard of placing the client's IP address in the X-Forwarded-For HTTP header. Aside from there is no guarantee that a request has a X-Forwarded-For header, there is also no guarantee that the X-Forwarded-For hasn't been SPOOFED.

Original Answer

Request.UserHostAddress

The above code provides the Client's IP address without resorting to looking up a collection. The Request property is available within Controllers (or Views). Therefore instead of passing a Page class to your function you can pass a Request object to get the same result:

public static string getIPAddress(HttpRequestBase request)
{
    string szRemoteAddr = request.UserHostAddress;
    string szXForwardedFor = request.ServerVariables["X_FORWARDED_FOR"];
    string szIP = "";

    if (szXForwardedFor == null)
    {
        szIP = szRemoteAddr;
    }
    else
    {
        szIP = szXForwardedFor;
        if (szIP.IndexOf(",") > 0)
        {
            string [] arIPs = szIP.Split(',');

            foreach (string item in arIPs)
            {
                if (!isPrivateIP(item))
                {
                    return item;
                }
            }
        }
    }
    return szIP;
}

div {
    display: flex;
    flex-direction: row; 
}

was the solution that worked for me. In some cases with div-lists this is needed.

some alternative direction values are row-reverse, column, column-reverse, unset, initial, inherit which do the things you expect them to do

Real power comes with understanding and implementation membership provider together with role provider. You can assign users into roles and according to that restriction you can apply different access roles for different user to controller actions or controller itself.

 [Authorize(Users = "Betty, Johnny")]
 public ActionResult SpecificUserOnly()
 {
     return View();
 }

or you can restrict according to group

[Authorize(Roles = "Admin, Super User")]
public ActionResult AdministratorsOnly()
{
    return View();
}

You can always do something shell-scripty like:

#!/usr/bin/node

var header = "Content-type: text/plain\n";
var hi = "Hello World from nodetest!";
console.log(header);
console.log(hi);

exit;

Here is a dplyr/tidyverse solution using the na_if() function:

dat %>% mutate_if(is.numeric, list(~na_if(., Inf)))

Note that this only replaces positive infinity with NA. Need to repeat if negative infinity values also need to be replaced.

dat %>% mutate_if(is.numeric, list(~na_if(., Inf))) %>% 
  mutate_if(is.numeric, list(~na_if(., -Inf)))

To convert any array (or any object) into a string using PHP, call the serialize():

$array = array( 1, 2, 3 );
$string = serialize( $array );
echo $string;

$string will now hold a string version of the array. The output of the above code is as follows:

a:3:{i:0;i:1;i:1;i:2;i:2;i:3;}

To convert back from the string to the array, use unserialize():

// $array will contain ( 1, 2, 3 )
$array = unserialize( $string );

It's actually all in the documentation.
JSONObject and JSONArray can both be used to replace the standard data structure.
To implement a setter simply call a remove(String name) before a put(String name, Object value).

Here's an simple example:

public class BasicDB {

private JSONObject jData = new JSONObject;

public BasicDB(String username, String tagline) {
    try {
        jData.put("username", username);
        jData.put("tagline" , tagline);
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

public String getUsername () { 
    String ret = null;
    try {
        ret = jData.getString("username");
    } catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    } 
    return ret;
}

public void setUsername (String username) { 
    try {
        jData.remove("username");
        jData.put("username" , username);
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

public String getTagline () {
    String ret = null;
    try {
        ret = jData.getString("tagline");
    } catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    } 
    return ret;
}

In response to the person who wanted to subtract one array from another...

If no more than say 1000 elements try this...

Setup a new variable to duplicate Array01 and call it Array03.

Now, use the bubble sort algorithm to compare the elements of Array01 with Array02 and whenever you find a match do the following to Array03...

 if (Array01[x]==Array02[y]) {Array03.splice(x,1);}

NB: We are modifying Array03 instead of Array01 so as not to screw up the nested loops of the bubble sort!

Finally, copy the contents of Array03 to Array01 with a simple assignment, and you're done.

The link you gave does actually describe the differences, but it's buried at the bottom of the page:

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

The conversion could be to normalize \r\n to \n (or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.

Put 0 as default in SQL or add 0 into your area of table

I would use the "Responsive Design View" available under Tools -> Web Developer -> Responsive Design View. It will let you test your CSS against different screen sizes.

Try apachectl -V:

$ apachectl -V
Server version: Apache/2.2.9 (Unix)
Server built:   Sep 18 2008 21:54:05
Server's Module Magic Number: 20051115:15
Server loaded:  APR 1.2.7, APR-Util 1.2.7
Compiled using: APR 1.2.7, APR-Util 1.2.7
... etc ...

If it does not work for you, run the command with sudo.

Delete parent:

$(document).on("click", ".remove", function() {
       $(this).parent().remove(); 
});

Delete all parents:

$(document).on("click", ".remove", function() { 
       $(this).parents().remove();
});

You could run it without the -jar command line argument if you happen to know the name of the main class you wish to run:

java -classpath .;myjar.jar;lib/referenced-class.jar my.package.MainClass

If perchance you are using linux, you should use ":" instead of ";" in the classpath.

Assuming your php install has the CURL extension, it is probably the easiest way (and most complete, if you wish).

Sample snippet:

//set POST variables
$url = 'http://domain.com/get-post.php';
$fields = array(
                      'lname'=>urlencode($last_name),
                      'fname'=>urlencode($first_name),
                      'email'=>urlencode($email)
               );

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

I couldn't believe how complicate the answer to this seemingly simple question is. Here are some references:

• Spring JIRA Ticket
• Another SO question
• Yet another SO question
• Very nice GitRepository that showcases the problem

There are many differnt things to consider:

1. By settingserver.context-path=/api in application.properties you can configure a prefix for everything.(Its server.context-path not server.contextPath !)
2. Spring Data controllers annotated with @RepositoryRestController that expose a repository as rest endpoint will use the environment variable spring.data.rest.base-path in application.properties. But plain @RestController won't take this into account. According to the spring data rest documentation there is an annotation @BasePathAwareController that you can use for that. But I do have problems in connection with Spring-security when I try to secure such a controller. It is not found anymore.

Another workaround is a simple trick. You cannot prefix a static String in an annotation, but you can use expressions like this:

@RestController
public class PingController {

  /**
   * Simple is alive test
   * @return <pre>{"Hello":"World"}</pre>
   */
  @RequestMapping("${spring.data.rest.base-path}/_ping")
  public String isAlive() {
    return "{\"Hello\":\"World\"}";
  }
}

Remove the TO_DATE in the WHERE clause

TO_DATE (alarm_datetime,'DD.MM.YYYY HH24:MI:SS')

and change the code to

alarm_datetime

The error comes from to_date conversion of a date column.

Added Explanation: Oracle converts your alarm_datetime into a string using its nls depended date format. After this it calls to_date with your provided date mask. This throws the exception.

We use object-scan for our data processing. It's conceptually very simple, but allows for a lot of cool stuff. Here is how you would solve your specific question

// const objectScan = require('object-scan');

const find = (id, input) => objectScan(['**'], {
  abort: true,
  rtn: 'value',
  filterFn: ({ value }) => value.id === id
})(input);

const data = [{ title: 'some title', channel_id: '123we', options: [{ channel_id: 'abc', image: 'http://asdasd.com/all-inclusive-block-img.jpg', title: 'All-Inclusive', options: [{ channel_id: 'dsa2', title: 'Some Recommends', options: [{ image: 'http://www.asdasd.com', title: 'Sandals', id: '1', content: {} }] }] }] }];

console.log(find('1', data));
// => { image: 'http://www.asdasd.com', title: 'Sandals', id: '1', content: {} }

Accept requests from these HTTP referrers (web sites)

Write localhost directory path

You can use either HttpClient or RestSharp. Since I do not know what your code is, here is an example using HttpClient:

using (var client = new HttpClient())
{
    // This would be the like http://www.uber.com
    client.BaseAddress = new Uri("Base Address/URL Address");

    // serialize your json using newtonsoft json serializer then add it to the StringContent
    var content = new StringContent(YourJson, Encoding.UTF8, "application/json") 

    // method address would be like api/callUber:SomePort for example
    var result = await client.PostAsync("Method Address", content);
    string resultContent = await result.Content.ReadAsStringAsync();   
}

You do not need to use substring at all since your format doesn't hold that info.

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";  
Date fechaNueva = format.parse(fechaStr);

System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29

Call the pd.DataFrame constructor directly:

df = pd.DataFrame(table, columns=headers)
df

   Heading1  Heading2

1         3         4

Let's take two questions, example string "2014-04-08 12:30"

How can I obtain a LocalDateTime instance from the given string?

import java.time.format.DateTimeFormatter
import java.time.LocalDateTime

final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm")

// Parsing or conversion
final LocalDateTime dt = LocalDateTime.parse("2014-04-08 12:30", formatter)

dt should allow you to all date-time related operations

How can I then convert the LocalDateTime instance back to a string with the same format?

final String date = dt.format(formatter)

There are multiple ways of doing that you can use either place or grid or even the packmethod.

Sample code:

from tkinter import *
root = Tk()

l = Label(root, text="hello" )
l.pack(padx=6, pady=4) # where padx and pady represent the x and y axis respectively
# well you can also use side=LEFT inside the pack method of the label widget.

To place a widget to on basis of columns and rows , use the grid method:

but = Button(root, text="hello" )
but.grid(row=0, column=1)

paramiko.SFTPClient

Sample Usage:

import paramiko
paramiko.util.log_to_file("paramiko.log")

# Open a transport
host,port = "example.com",22
transport = paramiko.Transport((host,port))

# Auth    
username,password = "bar","foo"
transport.connect(None,username,password)

# Go!    
sftp = paramiko.SFTPClient.from_transport(transport)

# Download
filepath = "/etc/passwd"
localpath = "/home/remotepasswd"
sftp.get(filepath,localpath)

# Upload
filepath = "/home/foo.jpg"
localpath = "/home/pony.jpg"
sftp.put(localpath,filepath)

# Close
if sftp: sftp.close()
if transport: transport.close()

A static library(.a) is a library that can be linked directly into the final executable produced by the linker,it is contained in it and there is no need to have the library into the system where the executable will be deployed.

A shared library(.so) is a library that is linked but not embedded in the final executable, so will be loaded when the executable is launched and need to be present in the system where the executable is deployed.

A dynamic link library on windows(.dll) is like a shared library(.so) on linux but there are some differences between the two implementations that are related to the OS (Windows vs Linux) :

A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined.

An SO library on Linux doesn't need special export statement to indicate exportable symbols, since all symbols are available to an interrogating process.

Short answer:

$ ssh-keygen -p

This will then prompt you to enter the keyfile location, the old passphrase, and the new passphrase (which can be left blank to have no passphrase).

If you would like to do it all on one line without prompts do:

$ ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile]

Important: Beware that when executing commands they will typically be logged in your ~/.bash_history file (or similar) in plain text including all arguments provided (i.e. the passphrases in this case). It is, therefore, is recommended that you use the first option unless you have a specific reason to do otherwise.

Notice though that you can still use -f keyfile without having to specify -P nor -N, and that the keyfile defaults to ~/.ssh/id_rsa, so in many cases, it's not even needed.

You might want to consider using ssh-agent, which can cache the passphrase for a time. The latest versions of gpg-agent also support the protocol that is used by ssh-agent.

Copying from a command line is unnecessary. I typed in the name of the DLL from the Start Window search. I chose See More Results. The one in the GAC was returned in the search window. I right clicked on it and said open file location. It opened in normal Windows Explorer. I copied the file. I closed the window. Done.

null is not zero. It is not a value, per se: it is a value outside the domain of the variable indicating missing or unknown data.

There is only one way to represent null in JSON. Per the specs (RFC 4627 and json.org):

2.1.  Values

A JSON value MUST be an object, array, number, or string, or one of
the following three literal names:

  false null true

additionally to @franc's answer you can use this from sql interface:

select 
    prosrc
from pg_trigger, pg_proc
where
 pg_proc.oid=pg_trigger.tgfoid
 and pg_trigger.tgname like '<name>'

(taken from here: http://www.postgresql.org/message-id/Pine.BSF.4.10.10009140858080.28013-100000@megazone23.bigpanda.com)

even shorter if you can lose the yearStart value:

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

while(yearStart < yearEnd+1){
  arr.push(yearStart++);
}

UPDATE: If you can use the ES6 syntax you can do it the way proposed here:

let yearStart = 2000;
let yearEnd = 2040;
let years = Array(yearEnd-yearStart+1)
    .fill()
    .map(() => yearStart++);

Quite simply the number is the precision of the timestamp, the fraction of a second held in the column:

  5  )

Note that I'm running on Linux so my TIMESTAMP column actually gives me precision to six places i.e. microseconds. This would also be the case on most (all?) flavours of Unix. On Windows the limit is three places i.e. milliseconds. (Is this still true of the most modern flavours of Windows - citation needed).

As might be expected, the documentation covers this. Find out more.

"when you create timestamp(9) this gives you nanos right"

Only if the OS supports it. As you can see, my OEL appliance does not:

SQL> alter table t23 add ts_nano timestamp(9)
  2  /

Table altered.

SQL> update t23 set ts_nano = systimestamp(9)
  2  /

1 row updated.

SQL> select * from t23
  2  /

(Those trailing zeroes could be a coincidence but they aren't.)

Considering that in most cases you don't want your entire data contract to have types supplied, but only those which are containing an abstract or interface, or list thereof; and also considering these instances are very rare and easily identifiable within your data entities, the easiest and least verbose way is to use

[JsonProperty(ItemTypeNameHandling = TypeNameHandling.Objects)]
public IEnumerable<ISomeInterface> Items { get; set; }

as attribute on your property containing the enumerable/list/collection. This will target only that list, and only append type information for the contained objects, like this:

{
  "Items": [
    {
      "$type": "Namespace.ClassA, Assembly",
      "Property": "Value"
    },
    {
      "$type": "Namespace.ClassB, Assembly",
      "Property": "Value",
      "Additional_ClassB_Property": 3
    }
  ]
}

Clean, simple, and located where the complexity of your data model is introduced, instead of hidden away in some converter.

I know this topic is super old, but, in case if someone's looking for an answer, as me, I'm posting my solution.

This solution works IF you don't mind having some extra data at the beginning of your file.

Basically, the idea is to, if file is not existing, to create it and append current date at the first line. Next, you can read the first line with fgets(fopen($file, 'r')), turn it into a DateTime object or anything (you can obviously use it raw, unless you saved it in a weird format) and voila - you have your creation date! For example my script to refresh my log file every 30 days looks like this:

if (file_exists($logfile)) {
            $now = new DateTime();
            $date_created = fgets(fopen($logfile, 'r'));
            if ($date_created == '') {
                file_put_contents($logfile, date('Y-m-d H:i:s').PHP_EOL, FILE_APPEND | LOCK_EX);
            }
            $date_created = new DateTime($date_created);
            $expiry = $date_created->modify('+ 30 days');
            if ($now >= $expiry) {
                unlink($logfile);
            }
        }

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

Look at a JUnit report. JUnit is already organized by package. Each package has (or can have) TestSuite classes, each of which in turn run multiple TestCases. Each TestCase can have multiple test methods of the form public void test*(), each of which will actually become an instance of the TestCase class to which they belong. Each test method (TestCase instance) has a name and a pass/fail criteria.

What my management requires is the concept of individual TestStep items, each of which reports their own pass/fail criteria. Failure of any test step must not prevent the execution of subsequent test steps.

In the past, test developers in my position organized TestCase classes into packages that correspond to the part(s) of the product under test, created a TestCase class for each test, and made each test method a separate "step" in the test, complete with its own pass/fail criteria in the JUnit output. Each TestCase is a standalone "test", but the individual methods, or test "steps" within the TestCase, must occur in a specific order.

The TestCase methods were the steps of the TestCase, and test designers got a separate pass/fail criterion per test step. Now the test steps are jumbled, and the tests (of course) fail.

For example:

Class testStateChanges extends TestCase

public void testCreateObjectPlacesTheObjectInStateA()
public void testTransitionToStateBAndValidateStateB()
public void testTransitionToStateCAndValidateStateC()
public void testTryToDeleteObjectinStateCAndValidateObjectStillExists()
public void testTransitionToStateAAndValidateStateA()
public void testDeleteObjectInStateAAndObjectDoesNotExist()
public void cleanupIfAnythingWentWrong()

Each test method asserts and reports its own separate pass/fail criteria. Collapsing this into "one big test method" for the sake of ordering loses the pass/fail criteria granularity of each "step" in the JUnit summary report. ...and that upsets my managers. They are currently demanding another alternative.

Can anyone explain how a JUnit with scrambled test method ordering would support separate pass/fail criteria of each sequential test step, as exemplified above and required by my management?

Regardless of the documentation, I see this as a serious regression in the JUnit framework that is making life difficult for lots of test developers.

try

var children = null;
$('tr').each(function(){
    var td = $(this).children('td:first');
    if(children == null)
        children = td;
    else
        children.add(td);
});

// children should now hold all the first td elements

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

Rebase and Cherry-pick is the only way you can keep clean commit history. Avoid using merge and avoid creating merge conflict. If you are using gerrit set one project to Merge if necessary and one project to cherry-pick mode and try yourself.

Python Implementation for @dhanushka's solution:

def process_rgb(rgb):
    hasText = False
    gray = cv2.cvtColor(rgb, cv2.COLOR_BGR2GRAY)
    morphKernel = cv2.getStructuringElement(cv2.MORPH_ELLIPSE, (3,3))
    grad = cv2.morphologyEx(gray, cv2.MORPH_GRADIENT, morphKernel)
    # binarize
    _, bw = cv2.threshold(grad, 0.0, 255.0, cv2.THRESH_BINARY | cv2.THRESH_OTSU)
    # connect horizontally oriented regions
    morphKernel = cv2.getStructuringElement(cv2.MORPH_RECT, (9, 1))
    connected = cv2.morphologyEx(bw, cv2.MORPH_CLOSE, morphKernel)
    # find contours
    mask = np.zeros(bw.shape[:2], dtype="uint8")
    _,contours, hierarchy = cv2.findContours(connected, cv2.RETR_CCOMP, cv2.CHAIN_APPROX_SIMPLE)
    # filter contours
    idx = 0
    while idx >= 0:
        x,y,w,h = cv2.boundingRect(contours[idx])
        # fill the contour
        cv2.drawContours(mask, contours, idx, (255, 255, 255), cv2.FILLED)
        # ratio of non-zero pixels in the filled region
        r = cv2.contourArea(contours[idx])/(w*h)
        if(r > 0.45 and h > 5 and w > 5 and w > h):
            cv2.rectangle(rgb, (x,y), (x+w,y+h), (0, 255, 0), 2)
            hasText = True
        idx = hierarchy[0][idx][0]
    return hasText, rgb

Partly based on StevenOjo's answer. I've tested this using a horizontal scrolling and no Bounce UICollectionView. cellSize is CollectionViewCell size. You can tweak factor to modify scrolling sensitivity.

override func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    targetContentOffset.pointee = scrollView.contentOffset
    var factor: CGFloat = 0.5
    if velocity.x < 0 {
        factor = -factor
    }
    let indexPath = IndexPath(row: (scrollView.contentOffset.x/cellSize.width + factor).int, section: 0)
    collectionView?.scrollToItem(at: indexPath, at: .left, animated: true)
}

Since bootstrap 4 use div class="form-row" in combination with div class="form-group col-X". X is the width you need. You will get nice inline columns. See fiddle.

<form class="form-horizontal" name="FORMNAME" method="post" action="ACTION" enctype="multipart/form-data">
    <div class="form-group">
        <label class="control-label col-sm-2" for="naam">Naam:&nbsp;*</label>
        <div class="col-sm-10">
            <input type="text" require class="form-control" id="naam" name="Naam" placeholder="Uw naam" value="{--NAAM--}" >
            <div id="naamx" class="form-error form-hidden">Wat is uw naam?</div>
        </div>
    </div>

    <div class="form-row">

        <div class="form-group col-5">
            <label class="control-label col-sm-4" for="telefoon">Telefoon:&nbsp;*</label>
            <div class="col-sm-12">
                <input type="tel" require class="form-control" id="telefoon" name="Telefoon" placeholder="Telefoon nummer" value="{--TELEFOON--}" >
                <div id="telefoonx" class="form-error form-hidden">Wat is uw telefoonnummer?</div>
            </div>
        </div>

        <div class="form-group col-5">
            <label class="control-label col-sm-4" for="email">E-mail: </label>
            <div class="col-sm-12">
                <input type="email" require class="form-control" id="email" name="E-mail" placeholder="E-mail adres" value="{--E-MAIL--}" >
                <div id="emailx" class="form-error form-hidden">Wat is uw e-mail adres?</div>
                    </div>
                </div>

        </div>

    <div class="form-group">
        <label class="control-label col-sm-2" for="titel">Titel:&nbsp;*</label>
        <div class="col-sm-10">
            <input type="text" require class="form-control" id="titel" name="Titel" placeholder="Titel van uw vraag of aanbod" value="{--TITEL--}" >
            <div id="titelx" class="form-error form-hidden">Wat is de titel van uw vraag of aanbod?</div>
        </div>
    </div>

Getting the anchor point of a div/table (left) = $("#whatever").offset().left; - ok!

Getting the anchor point of a div/table (right) you can use the code below.

 $("#whatever").width();

As David Olsson has said, you can use HTML in your string resources:

<resource>
    <string name="my_string">A string with <i>actual</i> <b>formatting</b>!</string>
</resources>

Then if you use getText(R.string.my_string) rather than getString(R.string.my_string) you get back a CharSequence rather than a String that contains the formatting embedded.

This is a simplified answer of how to run SQL query from Flask Shell

First, map your module (if your module/app is manage.py in the principal folder and you are in a UNIX Operating system), run:

export FLASK_APP=manage

Run Flask shell

flask shell

Import what we need::

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
db = SQLAlchemy(app)
from sqlalchemy import text

Run your query:

result = db.engine.execute(text("<sql here>").execution_options(autocommit=True))

This use the currently database connection which has the application.

Here is a code example that proves the fault in the class. I've checked: the problem occurs when using parse and also when you are only using format.
