_{Both the two most upvoted answers are wrong. It should have nothing to do with "store different/multiple languages". You can support Spanish characters like ñ and English, with just common varchar field and Latin1_General_CI_AS COLLATION, e.g.}

Short Version
You should use NVARCHAR/NCHAR whenever the ENCODING, which is determined by COLLATION of the field, doesn't support the characters needed.
Also, depending on the SQL Server version, you can use specific COLLATIONs, like Latin1_General_100_CI_AS_SC_UTF8 which is available since SQL Server 2019. Setting this collation on a VARCHAR field (or entire table/database), will use UTF-8 ENCODING for storing and handling the data on that field, allowing fully support UNICODE characters, and hence any languages embraced by it.

To FULLY UNDERSTAND:
_{To fully understand what I'm about to explain, it's mandatory to have the concepts of UNICODE, ENCODING and COLLATION all extremely clear in your head. If you don't, then first take a look below at my humble and simplified explanation on "What is UNICODE, ENCODING, COLLATION and UTF-8, and how they are related" section and supplied documentation links. Also, everything I say here is specific to Microsoft SQL Server, and how it stores and handles data in char/nchar and varchar/nvarchar fields.}

Let's say we wanna store a peculiar text on our MSSQL Server database. It could be an Instagram comment as "I love stackoverflow! ".
The plain English part would be perfectly supported even by ASCII, but since there are also an emoji, which is a character specified in the UNICODE standard, we need an ENCODING that supports this Unicode character.

MSSQL Server uses the COLLATION to determine what ENCODING is used on char/nchar/varchar/nvarchar fields. So, differently than a lot think, COLLATION is not only about sorting and comparing data, but also about ENCODING, and by consequence: how our data will be stored!

So, HOW WE KNOW WHAT IS THE ENCODING USED BY OUR COLLATION? With this:

SELECT COLLATIONPROPERTY( 'Latin1_General_CI_AI' , 'CodePage' ) AS [CodePage]
--returns 1252

This simple SQL returns the Windows Code Page for a COLLATION. A Windows Code Page is nothing more than another mapping to ENCODINGs. For the Latin1_General_CI_AI COLLATION it returns the Windows Code Page code 1252 , that maps to Windows-1252 ENCODING.
So, for a varchar column, with Latin1_General_CI_AI COLLATION, this field will handle its data using the Windows-1252 ENCODING, and only correctly store characters supported by this encoding.

If we check the Windows-1252 ENCODING specification Character List for Windows-1252, we will find out that this encoding won't support our emoji character. And if we still try it out:

OK, SO HOW CAN WE SOLVE THIS?? Actually, it depends, and that is GOOD!

NCHAR/NVARCHAR

Before SQL Server 2019 all we had was NCHAR and NVARCHAR fields. Some say they are UNICODE fields. THAT IS WRONG!. Again, it depends on the field's COLLATION and also SQLServer Version. Microsoft's "nchar and nvarchar (Transact-SQL)" documentation specifies perfectly:

Starting with SQL Server 2012 (11.x), when a Supplementary Character (SC) enabled collation is used, these data types store the full range of Unicode character data and use the UTF-16 character encoding. If a non-SC collation is specified, then these data types store only the subset of character data supported by the UCS-2 character encoding.

In other words, if we use SQL Server older that 2012, like SQL Server 2008 R2 for example, the ENCODING for those fields will use UCS-2 ENCODING which support a subset of UNICODE. But if we use SQL Server 2012 or newer, and define a COLLATION that has Supplementary Character enabled, than with our field will use the UTF-16 ENCODING, that fully supports UNICODE.

BUT WHAIT, THERE IS MORE! WE CAN USE UTF-8 NOW!!

CHAR/VARCHAR

Starting with SQL Server 2019, WE CAN USE CHAR/VARCHAR fields and still fully support UNICODE using UTF-8 ENCODING!!!

From Microsoft's "char and varchar (Transact-SQL)" documentation:

Starting with SQL Server 2019 (15.x), when a UTF-8 enabled collation is used, these data types store the full range of Unicode character data and use the UTF-8 character encoding. If a non-UTF-8 collation is specified, then these data types store only a subset of characters supported by the corresponding code page of that collation.

Again, in other words, if we use SQL Server older that 2019, like SQL Server 2008 R2 for example, we need to check the ENCODING using the method explained before. But if we use SQL Server 2019 or newer, and define a COLLATION like Latin1_General_100_CI_AS_SC_UTF8, then our field will use UTF-8 ENCODING which is by far the most used and efficient encoding that supports all the UNICODE characters.

Bonus Information:

Regarding the OP's observation on "I have seen that most of the European languages (German, Italian, English, ...) are fine in the same database in VARCHAR columns", I think it's nice to know why it is:

For the most common COLLATIONs, like the default ones as Latin1_General_CI_AI or SQL_Latin1_General_CP1_CI_AS the ENCODING will be Windows-1252 for varchar fields. If we take a look on it's documentation, we can see that it supports:

English, Irish, Italian, Norwegian, Portuguese, Spanish, Swedish. Plus also German, Finnish and French. And Dutch except the ? character

But as I said before, it's not about language, it's about what characters do you expect to support/store, as shown in the emoji example, or some sentence like "The electric resistance of a lithium battery is 0.5O" where we have again plain English, and a Greek letter/character "omega" (which is the symbol for resistance in ohms), which won't be correctly handled by Windows-1252 ENCODING.

Conclusion:

So, there it is! When use char/nchar and varchar/nvarchar depends on the characters that you want to support, and also the version of your SQL Server that will determines which COLLATIONs and hence the ENCODINGs you have available.

What is UNICODE, ENCODING, COLLATION and UTF-8, and how they are related
_{Note: all the explanations below are simplifications. Please, refer to the supplied documentation links to know all the details about those concepts.}

• UNICODE - Is a standard, a convention, that aims to regulate all the characters in a unified and organized table. In this table, every character has an unique number. This number is commonly called character's code point.
  UNICODE IS NOT AN ENCODING!

• ENCODING - Is a mapping between a character and a byte/bytes sequence. So a encoding is used to "transform" a character to bytes and also the other way around, from bytes to a character. Among the most popular ones are UTF-8, ISO-8859-1, Windows-1252 and ASCII. You can think of it as a "conversion table" (i really simplified here).

• COLLATION - That one is important. Even Microsoft's documentation doesn't let this clear as it should be. A Collation specifies how your data would be sorted, compared, AND STORED!. Yeah, I bet you was not expecting for that last one, right!? The collations on SQL Server determines too what would be the ENCODING used on that particular char/nchar/varchar/nvarchar field.

• ASCII ENCODING - Was one of the firsts encodings. It is both the character table (like an own tiny version of UNICODE) and its byte mappings. So it doesn't map a byte to UNICODE, but map a byte to its own character's table. Also, it always use only 7bits, and supported 128 different characters. It was enough to support all English letters upper and down cased, numbers, punctuation and some other limited number of characters. The problem with ASCII is that since it only used 7bits and almost every computer was 8bits at the time, there were another 128 possibilities of characters to be "explored", and everybody started to map this "available" bytes to its own table of characters, creating a lot of different ENCODINGs.

• UTF-8 ENCODING - This is another ENCODING, one of the most (if not the most) used ENCODING around. It uses variable byte width (one character can be from 1 to 6 bytes long, by specification) and fully supports all UNICODE characters.

• Windows-1252 ENCODING - Also one of the most used ENCODING, it's widely used on SQL Server. It's fixed-size, so every one character is always 1byte. It also supports a lot of accents, from various languages but doesn't support all existing, nor supports UNICODE. That's why your varchar field with a common collation like Latin1_General_CI_AS supports á,é,ñ characters, even that it isn't using a supportive UNICODE ENCODING.

Although NVARCHAR stores Unicode, you should consider by the help of collation also you can use VARCHAR and save your data of your local languages.

Just imagine the following scenario.

The collation of your DB is Persian and you save a value like '???' (Persian writing of Ali) in the VARCHAR(10) datatype. There is no problem and the DBMS only uses three bytes to store it.

However, if you want to transfer your data to another database and see the correct result your destination database must have the same collation as the target which is Persian in this example.

If your target collation is different, you see some question marks(?) in the target database.

Finally, remember if you are using a huge database which is for usage of your local language, I would recommend to use location instead of using too many spaces.

I believe the design can be different. It depends on the environment you work on.

Wanted to add my experience with converting. I had many text fields in ancient Linq2SQL code. This was to allow text columns present in indexes to be rebuilt ONLINE.

First I've known about the benefits for years, but always assumed that converting would mean some scary long queries where SQL Server would have to rebuild the table and copy everything over, bringing down my websites and raising my heartrate.

I was also concerned that the Linq2SQL could cause errors if it was doing some kind of verification of the column type.

Happy to report though, that the ALTER commands returned INSTANTLY - so they are definitely only changing table metadata. There may be some offline work happening to bring <8000 character data back to be in-table, but the ALTER command was instant.

I ran the following to find all columns needing conversion:

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] VARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'TEXT' order by table_name, column_name

SELECT concat('ALTER TABLE dbo.[', table_name, '] ALTER COLUMN [', column_name, '] NVARCHAR(MAX)'), table_name, column_name
FROM information_schema.columns where data_type = 'NTEXT' order by table_name, column_name

This gave me a nice list of queries, which I just selected and copied to a new window. Like I said - running this was instant.

Linq2SQL is pretty ancient - it uses a designer that you drag tables onto. The situation may be more complex for EF Code first but I haven't tackled that yet.

What you exactly wan't to do ?. To change Datatype of column you can simple use alter command as

ALTER TABLE table_name ALTER COLUMN LoginDate DateTime;

But remember there should valid Date only in this column however data-type is nvarchar.

If you wan't to convert data type while fetching data then you can use CONVERT function as,

CONVERT(data_type(length),expression,style)

eg:

SELECT CONVERT(DateTime, loginDate, 6)

This will return 29 AUG 13. For details about CONVERT function you can visit ,

http://www.w3schools.com/sql/func_convert.asp.

Remember, Always use DataTime data type for DateTime column.

Thank You

Always use nvarchar.

You may never need the double-byte characters for most applications. However, if you need to support double-byte languages and you only have single-byte support in your database schema it's really expensive to go back and modify throughout your application.

The cost of migrating one application from varchar to nvarchar will be much more than the little bit of extra disk space you'll use in most applications.

table { 
    table-layout:fixed; width:200px;
}
table tr {
    height: 20px;
}

10x10

The <span> tag will need to be set to display:block as it is an inline element and will ignore width.

so:

<style type="text/css"> span { width: 50px; display: block; } </style>

and then:

<li><span>&nbsp;</span>something</li>
<li><span>AND</span>something else</li>

I'm thinking unload is called all but at hard exist in 4.7. But, if you are playing around with older versions of .Net, try doing this in your loading method:

e.Handled = true;

I don't think older versions will unload until loading is handled. Just posting because I see others still asking this question, and haven't seen this proposed as a solution. I only touch .Net a few times a year, and ran into this a few years back. But, I wonder if it's as simple as unload not being called until loading has finished. Seems like it works for me, but again in newer .Net it seems to always call unload even if loading isn't marked as handled.

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, 
       t.inact, t.inadur, t.inadist, 
       t.smlct, t.smldur, t.smldist, 
       t.larct, t.lardur, t.lardist, 
       t.emptyct, t.emptydur 
FROM tmp t WHERE uid=x
ON DUPLICATE KEY UPDATE entct=t.entct, inact=t.inact, ...

The accepted answer doesn't cut it because if a user de-selects a row the list is not updated accordingly.

Here is what I suggest instead:

Private Sub CommandButton2_Click()
    Dim lItem As Long

    For lItem = 0 To ListBox1.ListCount - 1
        If ListBox1.Selected(lItem) = True Then
            MsgBox(ListBox1.List(lItem))
        End If
    Next
End Sub

A frequent source of these bugs is when you have a method that accepts a reference or pointer to an object but leaves ownership unclear. Style and commenting conventions can make this less likely.

Let the case where the function takes ownership of the object be the special case. In all situations where this happens, be sure to write a comment next to the function in the header file indicating this. You should strive to make sure that in most cases the module or class which allocates an object is also responsible for deallocating it.

Using const can help a lot in some cases. If a function will not modify an object, and does not store a reference to it that persists after it returns, accept a const reference. From reading the caller's code it will be obvious that your function has not accepted ownership of the object. You could have had the same function accept a non-const pointer, and the caller may or may not have assumed that the callee accepted ownership, but with a const reference there's no question.

Do not use non-const references in argument lists. It is very unclear when reading the caller code that the callee may have kept a reference to the parameter.

I disagree with the comments recommending reference counted pointers. This usually works fine, but when you have a bug and it doesn't work, especially if your destructor does something non-trivial, such as in a multithreaded program. Definitely try to adjust your design to not need reference counting if it's not too hard.

I would suggest defining your own package based on the following tex code; this gives you complete freedom. http://ubuntuforums.org/archive/index.php/t-331602.html

[object Object] This means somewhere the object is being converted to a string.

Converted to a string:

//Copy and paste in the browser console to see result

var product = {'name':'test'};
JSON.stringify(product + ''); 

Not converted to a string:

//Copy and paste in the browser console to see result

var product = {'name':'test'};
JSON.stringify(product);

Unless there is some other requirement not specified, I would simply convert your color image to grayscale and work with that only (no need to work on the 3 channels, the contrast present is too high already). Also, unless there is some specific problem regarding resizing, I would work with a downscaled version of your images, since they are relatively large and the size adds nothing to the problem being solved. Then, finally, your problem is solved with a median filter, some basic morphological tools, and statistics (mostly for the Otsu thresholding, which is already done for you).

Here is what I obtain with your sample image and some other image with a sheet of paper I found around:

The median filter is used to remove minor details from the, now grayscale, image. It will possibly remove thin lines inside the whitish paper, which is good because then you will end with tiny connected components which are easy to discard. After the median, apply a morphological gradient (simply dilation - erosion) and binarize the result by Otsu. The morphological gradient is a good method to keep strong edges, it should be used more. Then, since this gradient will increase the contour width, apply a morphological thinning. Now you can discard small components.

At this point, here is what we have with the right image above (before drawing the blue polygon), the left one is not shown because the only remaining component is the one describing the paper:

Given the examples, now the only issue left is distinguishing between components that look like rectangles and others that do not. This is a matter of determining a ratio between the area of the convex hull containing the shape and the area of its bounding box; the ratio 0.7 works fine for these examples. It might be the case that you also need to discard components that are inside the paper, but not in these examples by using this method (nevertheless, doing this step should be very easy especially because it can be done through OpenCV directly).

For reference, here is a sample code in Mathematica:

f = Import["http://thwartedglamour.files.wordpress.com/2010/06/my-coffee-table-1-sa.jpg"]
f = ImageResize[f, ImageDimensions[f][[1]]/4]
g = MedianFilter[ColorConvert[f, "Grayscale"], 2]
h = DeleteSmallComponents[Thinning[
     Binarize[ImageSubtract[Dilation[g, 1], Erosion[g, 1]]]]]
convexvert = ComponentMeasurements[SelectComponents[
     h, {"ConvexArea", "BoundingBoxArea"}, #1 / #2 > 0.7 &], 
     "ConvexVertices"][[All, 2]]
(* To visualize the blue polygons above: *)
Show[f, Graphics[{EdgeForm[{Blue, Thick}], RGBColor[0, 0, 1, 0.5], 
     Polygon @@ convexvert}]]

If there are more varied situations where the paper's rectangle is not so well defined, or the approach confuses it with other shapes -- these situations could happen due to various reasons, but a common cause is bad image acquisition -- then try combining the pre-processing steps with the work described in the paper "Rectangle Detection based on a Windowed Hough Transform".

that code should help:

var selected=[101,103];
var obj=$('#data');
for (var i in selected) {
    var val=selected[i];
    console.log(val);
   obj.find('option:[value='+val+']').attr('selected',1);
}

There is an accepted answer with more than 250 upvotes already. The reason I am still contributing is that the escape character required for echoing is not accepted by many editors (I am using, e.g., MS Code) and all other solutions require some third-party (non-Windows-default) pieces of software.

The work-around with using only plain batch commands is using PROMPT instead of ECHO. The PROMPT command accepts the escape character in an any-editor-friendly way as a $Echaracter sequence. (Simply replace the Esc in the ASCII Escape codes) with $E.

Here is a demo code:

@ECHO OFF

    :: Do not pollute environment with the %prompt.bak% variable
    :: ! forgetting ENDLOCAL at the end of the batch leads to prompt corruption
    SETLOCAL

    :: Old prompt settings backup
    SET prompt.bak=%PROMPT%

    :: Entering the "ECHO"-like section

        :: Forcing prompt to display after every command (see below)
        ECHO ON

        :: Setting the prompt using the ANSI Escape sequence(s)
        :: - Always start with $E[1A, otherwise the text would appear on a next line
        :: - Then the decorated text follows
        :: - And it all ends with $E30;40m, which makes the following command invisible
        ::   - assuming default background color of the screen
        @ PROMPT $E[1A$E[30;42mHELLO$E[30;40m

        :: An "empty" command that forces the prompt to display. 
        :: The word "rem" is displayed along with the prompt text but is made invisible
        rem

        :: Just another text to display
        @ PROMPT $E[1A$E[33;41mWORLD$E[30;40m
        rem

        :: Leaving the "ECHO"-like section
        @ECHO OFF

    :: Or a more readable version utilizing the cursor manipulation ASCII ESC sequences

        :: the initial sequence
        PROMPT $E[1A
        :: formating commands
        PROMPT %PROMPT%$E[32;44m
        :: the text
        PROMPT %PROMPT%This is an "ECHO"ed text...
        :: new line; 2000 is to move to the left "a lot"
        PROMPT %PROMPT%$E[1B$E[2000D
        :: formating commands fro the next line
        PROMPT %PROMPT%$E[33;47m
        :: the text (new line)
        PROMPT %PROMPT%...spreading over two lines
        :: the closing sequence
        PROMPT %PROMPT%$E[30;40m

        :: Looks like this without the intermediate comments:
        :: PROMPT $E[1A
        :: PROMPT %PROMPT%$E[32;44m
        :: PROMPT %PROMPT%This is an "ECHO"ed text...
        :: PROMPT %PROMPT%$E[1B$E[2000D
        :: PROMPT %PROMPT%$E[33;47m
        :: PROMPT %PROMPT%...spreading over two lines
        :: PROMPT %PROMPT%$E[30;40m

        :: show it all at once!
        ECHO ON
        rem
        @ECHO OFF

    :: End of "ECHO"-ing

    :: Setting prompt back to its original value
    :: - We prepend the settings with $E[37;40m in case
    ::   the original prompt settings do not specify color
    ::   (as they don't by default).
    :: - If they do, the $E[37;40m will become overridden, anyway.
    :: ! It is important to write this command 
    ::   as it is with `ENDLOCAL` and in the `&` form.
    ENDLOCAL & PROMPT $E[37;40m%prompt.bak%

EXIT /B 0

NOTE: The only drawback is that this technique collides with user cmd color settings (color command or settings) if not known explicitly.

-- Hope this helps as thi is the only solution acceptable for me for the reasons mentioned at the beginning. --

EDIT:

Based on comments, I am enclosing another snippet inspired by @Jeb. It:

• Shows how to obtain and use the "Esc" character runtime (rather than entering it to an editor) (Jeb's solution)
• Uses "native" ECHO command(s)
• So it does not affect local PROMPT value
• Demonstrates that coloring the ECHO output inevitably affect PROMPT color so the color must be reset, anyway

In addition to the above answers here is how you might handle a 500 series response from your api where you receive an error message encoded in json:

function callApi(url) {
  return fetch(url)
    .then(response => {
      if (response.ok) {
        return response.json().then(response => ({ response }));
      }

      return response.json().then(error => ({ error }));
    })
  ;
}

1. Open your SQL command line and type the following:

   SQL> connect / as sysdba
   

2. Once connected,you can enter the following query to get details of username and password:

   SQL> select username,password from dba_users;
   

3. This will list down the usernames,but passwords would not be visible.But you can identify the particular username and then change the password for that user. For changing the password,use the below query:

   SQL> alter user username identified by password;
   

4. Here username is the name of user whose password you want to change and password is the new password.

def upper(name: String) : String = { 
var uppper : String  =  name.toUpperCase()
uppper
}

val toUpperName = udf {(EmpName: String) => upper(EmpName)}
val emp_details = """[{"id": "1","name": "James Butt","country": "USA"},
{"id": "2", "name": "Josephine Darakjy","country": "USA"},

val df_emp = spark.read.json(Seq(emp_details).toDS())
val df_name=df_emp.select($"id",$"name")
val df_upperName= df_name.withColumn("name",toUpperName($"name")).filter("id='5'")
display(df_upperName)

this will give error org.apache.spark.SparkException: Task not serializable at org.apache.spark.util.ClosureCleaner$.ensureSerializable(ClosureCleaner.scala:304)

Solution -

import java.io.Serializable;

object obj_upper extends Serializable { 
  def upper(name: String) : String = 
  {
    var uppper : String  =  name.toUpperCase()
    uppper
  }

}

val df_upperName= 
df_name.withColumn("name",obj_upper.toUpperName($"name")).filter("id='5'")
display(df_upperName)

To delete every branch except the one that you currently have checked out:

for b in `git branch --merged | grep -v \*`; do git branch -D $b; done

I would recommend changing git branch -D $b to an echo $b the first few times to make sure that it deletes the branches that you intend.

According to the official docs, browsers do not like it when you use the

Access-Control-Allow-Origin: "*"

header if you're also using the

Access-Control-Allow-Credentials: "true"

header. Instead, they want you to allow their origin specifically. If you still want to allow all origins, you can do some simple Apache magic to get it to work (make sure you have mod_headers enabled):

Header set Access-Control-Allow-Origin "%{HTTP_ORIGIN}e" env=HTTP_ORIGIN

Browsers are required to send the Origin header on all cross-domain requests. The docs specifically state that you need to echo this header back in the Access-Control-Allow-Origin header if you are accepting/planning on accepting the request. That's what this Header directive is doing.

Interpretation for the author

var o = JObject.Parse(response);
var a = o.SelectToken("data").Select(jt => jt.ToObject<TheUser>()).ToList();

Sorry about the confusion, this should be the correct approach. Do you want only to capture 'bad' only, not things like 'good'; Or just any non-numerical values?

For gcc you want to omit any -O1 -O2 or -O3 options passed to the compiler or if you already have them you can append the -O0 option to turn it off again. It might also help you to add -g for debug so that you can see the c source and disassembled machine code in your debugger.

The data-* attributes is used to store custom data private to the page or application

So Bootstrap uses these attributes for saving states of objects

W3School data-* description

Write your own method, and use it everywhere you want a number value:

function getNum(val) {
   if (isNaN(val)) {
     return 0;
   }
   return val;
}

Two more reasons not to use inline handlers:

They can require tedious quote escaping issues

Given an arbitrary string, if you want to be able to construct an inline handler that calls a function with that string, for the general solution, you'll have to escape the attribute delimiters (with the associated HTML entity), and you'll have to escape the delimiter used for the string inside the attribute, like the following:

const str = prompt('What string to display on click?', 'foo\'"bar');
const escapedStr = str
  // since the attribute value is going to be using " delimiters,
  // replace "s with their corresponding HTML entity:
  .replace(/"/g, '"')
  // since the string literal inside the attribute is going to delimited with 's,
  // escape 's:
  .replace(/'/g, "\\'");
  
document.body.insertAdjacentHTML(
  'beforeend',
  '<button onclick="alert(\'' + escapedStr + '\')">click</button>'
);

That's incredibly ugly. From the above example, if you didn't replace the 's, a SyntaxError would result, because alert('foo'"bar') is not valid syntax. If you didn't replace the "s, then the browser would interpret it as an end to the onclick attribute (delimited with "s above), which would also be incorrect.

If one habitually uses inline handlers, one would have to make sure to remember do something similar to the above (and do it right) every time, which is tedious and hard to understand at a glance. Better to avoid inline handlers entirely so that the arbitrary string can be used in a simple closure:

const str = prompt('What string to display on click?', 'foo\'"bar');
const button = document.body.appendChild(document.createElement('button'));
button.textContent = 'click';
button.onclick = () => alert(str);

Isn't that so much nicer?

The scope chain of an inline handler is extremely peculiar

What do you think the following code will log?

let disabled = true;

<form>
  <button onclick="console.log(disabled);">click</button>
</form>

Try it, run the snippet. It's probably not what you were expecting. Why does it produce what it does? Because inline handlers run inside with blocks. The above code is inside three with blocks: one for the document, one for the <form>, and one for the <button>:

let disabled = true;

<form>
  <button onclick="console.log(disabled);">click</button>
</form>

Since disabled is a property of the button, referencing disabled inside the inline handler refers to the button's property, not the outer disabled variable. This is quite counter-intuitive. with has many problems: it can be the source of confusing bugs and significantly slows down code. It isn't even permitted at all in strict mode. But with inline handlers, you're forced to run the code through withs - and not just through one with, but through multiple nested withs. It's crazy.

with should never be used in code. Because inline handlers implicitly require with along with all its confusing behavior, inline handlers should be avoided as well.

Based on all your remarks here is my proposal that worked for me :

 private final class CustomHttpServletRequest extends HttpServletRequestWrapper {

    private final Map<String, String[]> queryParameterMap;
    private final Charset requestEncoding;

    public CustomHttpServletRequest(HttpServletRequest request) {
        super(request);
        queryParameterMap = getCommonQueryParamFromLegacy(request.getParameterMap());

        String encoding = request.getCharacterEncoding();
        requestEncoding = (encoding != null ? Charset.forName(encoding) : StandardCharsets.UTF_8);
    }

    private final Map<String, String[]> getCommonQueryParamFromLegacy(Map<String, String[]> paramMap) {
        Objects.requireNonNull(paramMap);

        Map<String, String[]> commonQueryParamMap = new LinkedHashMap<>(paramMap);

        commonQueryParamMap.put(CommonQueryParams.PATIENT_ID, new String[] { paramMap.get(LEGACY_PARAM_PATIENT_ID)[0] });
        commonQueryParamMap.put(CommonQueryParams.PATIENT_BIRTHDATE, new String[] { paramMap.get(LEGACY_PARAM_PATIENT_BIRTHDATE)[0] });
        commonQueryParamMap.put(CommonQueryParams.KEYWORDS, new String[] { paramMap.get(LEGACY_PARAM_STUDYTYPE)[0] });

        String lowerDateTime = null;
        String upperDateTime = null;

        try {
            String studyDateTime = new SimpleDateFormat("yyyy-MM-dd").format(new SimpleDateFormat("dd-MM-yyyy").parse(paramMap.get(LEGACY_PARAM_STUDY_DATE_TIME)[0]));

            lowerDateTime = studyDateTime + "T23:59:59";
            upperDateTime = studyDateTime + "T00:00:00";

        } catch (ParseException e) {
            LOGGER.error("Can't parse StudyDate from query parameters : {}", e.getLocalizedMessage());
        }

        commonQueryParamMap.put(CommonQueryParams.LOWER_DATETIME, new String[] { lowerDateTime });
        commonQueryParamMap.put(CommonQueryParams.UPPER_DATETIME, new String[] { upperDateTime });

        legacyQueryParams.forEach(commonQueryParamMap::remove);
        return Collections.unmodifiableMap(commonQueryParamMap);

    }

    }

    @Override
    public Map<String, String[]> getParameterMap() {
            return queryParameterMap; // unmodifiable to uphold the interface contract.
        }

        @Override
        public Enumeration<String> getParameterNames() {
            return Collections.enumeration(queryParameterMap.keySet());
        }

        @Override
        public String getQueryString() {
            // @see : https://stackoverflow.com/a/35831692/9869013
            // return queryParameterMap.entrySet().stream().flatMap(entry -> Stream.of(entry.getValue()).map(value -> entry.getKey() + "=" + value)).collect(Collectors.joining("&")); // without encoding !!
            return queryParameterMap.entrySet().stream().flatMap(entry -> encodeMultiParameter(entry.getKey(), entry.getValue(), requestEncoding)).collect(Collectors.joining("&"));

            } catch (UnsupportedEncodingException e) {
                throw new IllegalArgumentException("Cannot url encode " + value, e);
            }
        }

        @Override
        public ServletInputStream getInputStream() throws IOException {
            throw new UnsupportedOperationException("getInputStream() is not implemented in this " + CustomHttpServletRequest.class.getSimpleName() + " wrapper");
        }

    }

note : queryString() requires to process ALL the values for each KEY and don't forget to encodeUrl() when adding your own param values, if required

As a limitation, if you call request.getParameterMap() or any method that would call request.getReader() and begin reading, you will prevent any further calls to request.setCharacterEncoding(...)

Disable:

I think, bwawok's answer is wrong at some point:

if you do

git reset --soft c14809fa

It will make your local files changed to be like they were then, but leave your history etc. the same.

According to manual: git-reset, "git reset --soft"...

does not touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

So it will "remove" newer commits from the branch. This means, after looking at your old code, you cannot go to the newest commit in this branch again, easily. So it does the opposide as described by bwawok: Local files are not changed (they look exactly as before "git reset --soft"), but the history is modified (branch is truncated after the specified commit).

The command for bwawok's answer might be:

git checkout <commit>

You can use this to peek at old revision: How did my code look yesterday?

(I know, I should put this in comments to this answer, but stackoverflow does not allow me to do so! My reputation is too low.)

A bit late in the game, i know... but this is what i recently did. It is slightly different than yours, but allows the programmer to dictate what the equality operation needs to be (predicate). Which i find very useful when dealing with different types, since i then have a generic way of doing it regardless of object type and <T> built in equality operator.

It also has a very very small memory footprint, and is very, very fast/efficient... if you care about that.

At worse, you'll just add this to your list of extensions.

Anyway... here it is.

 public static int IndexOf<T>(this IEnumerable<T> source, Func<T, bool> predicate)
 {
     int retval = -1;
     var enumerator = source.GetEnumerator();

     while (enumerator.MoveNext())
     {
         retval += 1;
         if (predicate(enumerator.Current))
         {
             IDisposable disposable = enumerator as System.IDisposable;
             if (disposable != null) disposable.Dispose();
             return retval;
         }
     }
     IDisposable disposable = enumerator as System.IDisposable;
     if (disposable != null) disposable.Dispose();
     return -1;
 }

Hopefully this helps someone.

It appears that the :include functionality was changed with Rails 2.1. Rails used to do the join in all cases, but for performance reasons it was changed to use multiple queries in some circumstances. This blog post by Fabio Akita has some good information on the change (see the section entitled "Optimized Eager Loading").

This message digital envelope routines: EVP_DecryptFInal_ex: bad decrypt can also occur when you encrypt and decrypt with an incompatible versions of openssl.

The issue I was having was that I was encrypting on Windows which had version 1.1.0 and then decrypting on a generic Linux system which had 1.0.2g.

It is not a very helpful error message!

Working solution:

A possible solution from @AndrewSavinykh that worked for many (see the comments):

Default digest has changed between those versions from md5 to sha256. One can specify the default digest on the command line as -md sha256 or -md md5 respectively

You can simply chain as many split-path as you need:

$rootPath = $scriptPath | split-path | split-path

This should be quite simple with something like this :

public static String toBinary(int number){
    StringBuilder sb = new StringBuilder();

    if(number == 0)
        return "0";
    while(number>=1){
        sb.append(number%2);
        number = number / 2;
    }

    return sb.reverse().toString();

}

Alright, if don't need your divider color to be changed just apply alpha to the divider decorations.

Example for GridLayoutManager with transparency:

DividerItemDecoration horizontalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.HORIZONTAL);
        horizontalDividerItemDecoration.getDrawable().setAlpha(50);
        DividerItemDecoration verticalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.VERTICAL);
        verticalDividerItemDecoration.getDrawable().setAlpha(50);
        my_recycler.addItemDecoration(horizontalDividerItemDecoration);
        my_recycler.addItemDecoration(verticalDividerItemDecoration);

You can still change the color of dividers by just setting color filters to it.

Example for GridLayoutManager by setting tint:

DividerItemDecoration horizontalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.HORIZONTAL);
        horizontalDividerItemDecoration.getDrawable().setTint(getResources().getColor(R.color.colorAccent));
        DividerItemDecoration verticalDividerItemDecoration = new DividerItemDecoration(WishListActivity.this,
                DividerItemDecoration.VERTICAL);
        verticalDividerItemDecoration.getDrawable().setAlpha(50);
        my_recycler.addItemDecoration(horizontalDividerItemDecoration);
        my_recycler.addItemDecoration(verticalDividerItemDecoration);

Additionally you can also try setting color filter,

 horizontalDividerItemDecoration.getDrawable().setColorFilter(colorFilter);

Thanks @Kit Ho for your answer. I used your code and found that I kept running into errors where my InputStream was always null and ClassNotFound exceptions when the JSONObject was being created. Here's my version of your code which does the trick for me:

import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import org.apache.commons.io.IOUtils;

import org.json.JSONObject;
public class JSONParsing {
    public static void main(String[] args) throws Exception {
        File f = new File("file.json");
        if (f.exists()){
            InputStream is = new FileInputStream("file.json");
            String jsonTxt = IOUtils.toString(is, "UTF-8");
            System.out.println(jsonTxt);
            JSONObject json = new JSONObject(jsonTxt);       
            String a = json.getString("1000");
            System.out.println(a);   
        }
    }
}

I found this answer to be enlightening about the difference between FileInputStream and getResourceAsStream. Hope this helps someone else too.

Its a bit late but if you don't want to use a div specifically, I usually do it like this...

var ajax_image = "<img src='/images/Loading.gif' alt='Loading...' />";
$('#ReplaceDiv').html(ajax_image);

ReplaceDiv is the div that the Ajax inserts too. So when it arrives, the image is replaced.

NOTE: This is an old answer, for PHP 5.5 and below. PHP 5.6+ supports default arguments

In PHP 5.5 and below, you can achieve this by using one of these 2 methods:

• using the func_num_args() and func_get_arg() functions;
• using NULL arguments;

How to use

function method_1()
{
  $arg1 = (func_num_args() >= 1)? func_get_arg(0): "default_value_for_arg1";
  $arg2 = (func_num_args() >= 2)? func_get_arg(1): "default_value_for_arg2";
}

function method_2($arg1 = null, $arg2 = null)
{
  $arg1 = $arg1? $arg1: "default_value_for_arg1";
  $arg2 = $arg2? $arg2: "default_value_for_arg2";
}

I prefer the second method because it's clean and easy to understand, but sometimes you may need the first method.

Do aman 2 sendfile. You only need to open the source file on the client and destination file on the server, then call sendfile and the kernel will chop and move the data.

Did you try cal.getTime()? This gets the date representation.

You might also want to look at the javadoc.

... or if you really want to use NOT IN you can use

SELECT * FROM match WHERE id NOT IN ( SELECT id FROM email WHERE id IS NOT NULL)

I'd say use the PID for whatever purpose you're obtaining it and handle the errors gracefully. Otherwise, it's a classic race (the PID may be valid when you check it's valid, but go away an instant later)

Non of the above solved my problem, you can check pod version using two commands

1. pod --version
2. gem which cocoapods

In my case pod --version always showed "1.5.0" while gem which cocopods shows Library/Ruby/Gems/2.3.0/gems/cocoapods-1.9.0/lib/cocoapods.rb. I tried every thing but unable to update version showed from pod --version. sudo gem install cocopods result in installing latest version but pod --version always showing previous version. Finally I tried these commands

1. sudo gem update
2. sudo gem uninstall cocoapods
3. sudo gem install cocopods
4. pod setup``pod install

catch for me was sudo gem update. Hopefully it will help any body else.

    var vvg = eval( zvg );
    var raw = vvg();

    var svg = document.getElementById( eid );
    svg.setAttributeNS(null,"d", raw );
    svg.setAttributeNS(null,"fill","green");
    svg.setAttributeNS(null,"onlick", eid + ".style.fill=#FF0000");
    return;
}

You could call with:

<img src="" onerror="buildscript">

Now you can add colors by sub element and manipulate all elements of the dom directly. It is important to implement your viewbox and height width first on the svg html, not done in the example above.

There is no need to make your code 10 pages when it could be one... but who am I to argue. Better use PHP while your at it.

The inner element that svg builds on is a simple <svg lamencoding id=parenteid><path id=eid><svg> with nothing else.

Would the use of <caption> be allowed?

  <caption> Title of List </caption>

I usually do something similar to the approach given by How to Use JavaScript to Print a PDF (eHow.com), using an iframe.

1. a function to house the print trigger...

   function printTrigger(elementId) {
       var getMyFrame = document.getElementById(elementId);
       getMyFrame.focus();
       getMyFrame.contentWindow.print();
   }
   

2. an button to give the user access...

   (an onClick on an a or button or input or whatever you wish)

   <input type="button" value="Print" onclick="printTrigger('iFramePdf');" />
   

3. an iframe pointing to your PDF...

   <iframe id="iFramePdf" src="myPdfUrl.pdf" style="display:none;"></iframe>
   

Bonus Idea #1 - Create the iframe and add it to your page within the printTrigger(); so that the PDF isn't loaded until the user clicks your "Print" button, then the javascript can attack! the iframe and trigger the print dialog.

Bonus Idea #2 - Extra credit if you disable your "Print" button and give the user a little loading spinner or something after they click it, so that they know something's in process instead of clicking it repeatedly!

The path /usr/local/bin/composer is not in your PATH, executables in that folder won't be found.

Delete the folder /usr/local/bin/composer, then run

$ mv composer.phar /usr/local/bin/composer

This moves composer.phar into /usr/local/bin/ and renames it into composer (which is still an executable, not a folder).

Then just use it like:

$ composer ...

You can use a single group for seconds/minutes. The following expression may suit your needs:

([0-9]+)\s*(seconds|minutes)

Online demo

enter your python interactive mode then:

import sys

sys.path

it will print your path. Check wether flask is installed in the sys.path.

For MacOS, python path is under /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

But pip'll install python package by default under /Library/Python/2.7/site-packages

That's why it doesn't work for MacOS.

The three top-rated answers have a weakness.

If your dataframe looks like this

df <- data.frame(Time=c(1,2), In=c(2,3), Out=c(3,4), Files=c(4,5))

> df
  Time In Out Files
1    1  2   3     4
2    2  3   4     5

then it's a poor solution to use

> df2[,c(1,3,2,4)]

It does the job, but you have just introduced a dependence on the order of the columns in your input.

This style of brittle programming is to be avoided.

The explicit naming of the columns is a better solution

data[,c("Time", "Out", "In", "Files")]

Plus, if you intend to reuse your code in a more general setting, you can simply

out.column.name <- "Out"
in.column.name <- "In"
data[,c("Time", out.column.name, in.column.name, "Files")]

which is also quite nice because it fully isolates literals. By contrast, if you use dplyr's select

data <- data %>% select(Time, out, In, Files)

then you'd be setting up those who will read your code later, yourself included, for a bit of a deception. The column names are being used as literals without appearing in the code as such.

I agree with Als that you can not initialize at time of defining the structure in C. But you can initialize the structure at time of creating instance shown as below.

In C,

 struct s {
        int i;
        int j;
    };

    struct s s_instance = { 10 ,20 };

in C++ its possible to give direct value in definition of structure shown as below

struct s {
    int i;

    s(): i(10)
    {
    }
};

URL-encoded payload must be provided on the body parameter of the http.NewRequest(method, urlStr string, body io.Reader) method, as a type that implements io.Reader interface.

Based on the sample code:

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "strconv"
    "strings"
)

func main() {
    apiUrl := "https://api.com"
    resource := "/user/"
    data := url.Values{}
    data.Set("name", "foo")
    data.Set("surname", "bar")

    u, _ := url.ParseRequestURI(apiUrl)
    u.Path = resource
    urlStr := u.String() // "https://api.com/user/"

    client := &http.Client{}
    r, _ := http.NewRequest(http.MethodPost, urlStr, strings.NewReader(data.Encode())) // URL-encoded payload
    r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
    r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
    r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))

    resp, _ := client.Do(r)
    fmt.Println(resp.Status)
}

resp.Status is 200 OK this way.

This is a method you can do using the basic JavaScript, which is works for me:

var v_Result;
function OneClick() {
    v_Result = false;
    window.setTimeout(OneClick_Nei, 500)
    function OneClick_Nei() {
        if (v_Result != false) return;
        alert("single click");
    }
}
function TwoClick() {
    v_Result = true;
    alert("double click");
}

As far as I'm aware this isn't possible with HTML and CSS.

I've found out the solution! Thanks to Firebug ;)

//"markers" is an array that I declared which contains all the marker of the map
//"i" is the index of the marker in the array that I want to trigger the OnClick event

//V2 version is:
GEvent.trigger(markers[i], 'click');

//V3 version is:
google.maps.event.trigger(markers[i], 'click');

//More Efficiently
public class Multiples {
    public static void main(String[]args) {

        int j = 5;

        System.out.println(j % 4 == 0);

    }
}

There are many reasons as to why the SDK Manager won't open. Rather than trying each one of them blindly, I recommend running the android.bat in a command window so you can read the error message and apply the correct fix.

Try this:

select * from all_constraints where r_constraint_name in (select constraint_name 
from all_constraints where table_name='YOUR_TABLE_NAME');

The solution is to simply not declare width: 100%.

The default is width: auto, which for block-level elements (such as div), will take the "full space" available anyway (different to how width: 100% does it).

See: http://jsfiddle.net/U7PhY/2/

Just in case it's not already clear from my answer: just don't set a width on the child div.

You might instead be interested in box-sizing: border-box.

Even we can refresh particular connection and in turn it will refresh all the pivots linked to it.

For this code I have created slicer from table present in Excel:

        ServerNameRaw = ActiveWorkbook.SlicerCaches("Slicer_ServerName").VisibleSlicerItemsList(1)
        ServerName = Replace(Split(ServerNameRaw, "[")(3), "]", "")

        CubeNameRaw = ActiveWorkbook.SlicerCaches("Slicer_CubeName").VisibleSlicerItemsList(1)
        CubeName = Replace(Split(CubeNameRaw, "[")(3), "]", "")

        If CubeName = "All" Or ServerName = "All" Then
            MsgBox "Please Select One Cube and Server Name", vbOKOnly, "Slicer Info"
        Else
            ConnectionString = GetConnectionString(ServerName, CubeName)
            UpdateAllQueryTableConnections ConnectionString, CubeName
        End If
    End Sub

I know it is a pointed question, and the op wanted to load different properties file.

My answer is, doing custom hacks like this is a terrible idea.

If you are using spring-boot with a cloud provider such as cloud foundry, please do yourself a favor and use cloud config services

https://spring.io/projects/spring-cloud-config

It loads and merges default/dev/project-default/project-dev specific properties like magic

Again, Spring boot already gives you enough ways to do this right https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

Please do not re-invent the wheel.

items=re.findall("token.*$",s,re.MULTILINE)
>>> for x in items:

you can also get the line if there are other characters before token

items=re.findall("^.*token.*$",s,re.MULTILINE)

The above works like grep token on unix and keyword 'in' or .contains in python and C#

s='''
qwertyuiop
asdfghjkl

zxcvbnm
token qwerty

asdfghjklñ
'''

http://pythex.org/ matches the following 2 lines

....
....
token qwerty

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

It seems that you didn't update the counter is the script, use counter++

#include<stdio.h>
int main()
{
    int a,b,i,c,j;
    printf("\n Enter the two no. in between you want to check:");
    scanf("%d%d",&a,&c);
    printf("%d-%d\n",a,c);
    for(j=a;j<=c;j++)
    {
        b=0;
        for(i=1;i<=c;i++)
        {
            if(j%i==0)
            {
                 b++;
            }
        }
        if(b==2)
        {
            printf("\nPrime number:%d\n",j);
        }
        else
        {
            printf("\n\tNot prime:%d\n",j);
        }
    }
}

constraints are conditions, that can validate specific condition. Constraints related with database are Domain integrity, Entity integrity, Referential Integrity, User Defined Integrity constraints etc.

You can not run/execute an .exe file that is in the users local machine or through a site. The user must first download the exe file and then run the executable file.
So there is no possible way

The following code works only when the EXE is Present in the User's Machine.

<a href = "C:\folder_name\program.exe">

actually you don't need to replace this all....

there are 2 ways to do this. One is to use autoclose property, the other (alternativ) way is to use the on change property thats fired by the input when selecting a Date.

HTML

<div class="container">
    <div class="hero-unit">
        <input type="text" placeholder="Sample 1: Click to show datepicker" id="example1">
    </div>
    <div class="hero-unit">
        <input type="text" placeholder="Sample 2: Click to show datepicker" id="example2">
    </div>
</div>

jQuery

$(document).ready(function () {
    $('#example1').datepicker({
        format: "dd/mm/yyyy",
        autoclose: true
    });

    //Alternativ way
    $('#example2').datepicker({
      format: "dd/mm/yyyy"
    }).on('change', function(){
        $('.datepicker').hide();
    });

});

this is all you have to do :)

HERE IS A FIDDLE to see whats happening.

Fiddleupdate on 13 of July 2016: CDN wasnt present anymore

According to your EDIT:

$('#example1').datepicker().on('changeDate', function (ev) {
    $('#example1').Close();
});

Here you take the Input (that has no Close-Function) and create a Datepicker-Element. If the element changes you want to close it but you still try to close the Input (That has no close-function).

Binding a mouseup event to the document state may not be the best idea because you will fire all containing scripts on each click!

Thats it :)

EDIT: August 2017 (Added a StackOverFlowFiddle aka Snippet. Same as in Top of Post)

EDIT: December 2018 Obviously Bootstrap-Datepicker doesnt work with jQuery 3.x see this to fix

The short answer is adb is used via command line. find adb.exe on your machine, add it to the path and use it from cmd on windows.

"adb devices" will give you a list of devices adb can talk to. your emulation platform should be on the list. just type adb to get a list of commands and what they do.

 var objectList = objects.ToList();
  objectList[0].SimpleInt=5;

This will update the original object as well. The new list will contain references to the objects contained within it, just like the original list. You can change the elements either and the update will be reflected in the other.

Now if you update a list (adding or deleting an item) that will not be reflected in the other list.

Generate a random password of length 8 to 32 characters with at least 1 lower case, 1 upper case, 1 number, 1 special char (!@$&)

function getRandomUpperCase() {
   return String.fromCharCode( Math.floor( Math.random() * 26 ) + 65 );
}

function getRandomLowerCase() {
   return String.fromCharCode( Math.floor( Math.random() * 26 ) + 97 );
} 

function getRandomNumber() {
   return String.fromCharCode( Math.floor( Math.random() * 10 ) + 48 );
}

function getRandomSymbol() {
    // const symbol = '!@#$%^&*(){}[]=<>/,.|~?';
    const symbol = '!@$&';
    return symbol[ Math.floor( Math.random() * symbol.length ) ];
}

const randomFunc = [ getRandomUpperCase, getRandomLowerCase, getRandomNumber, getRandomSymbol ];

function getRandomFunc() {
    return randomFunc[Math.floor( Math.random() * Object.keys(randomFunc).length)];
}

function generatePassword() {
    let password = '';
    const passwordLength = Math.random() * (32 - 8) + 8;
    for( let i = 1; i <= passwordLength; i++ ) {
        password += getRandomFunc()();
    }
    //check with regex
    const regex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,32}$/
    if( !password.match(regex) ) {
        password = generatePassword();
    }
    return password;
}

console.log( generatePassword() );

My brute force method to get this to work was just:

1. Dump the table - mysqldump -u user -p database table > dump.sql
2. Find and replace a couple patterns - find /path/to/dump.sql -type f -exec sed -i 's/old_string/new_string/g' {} \;, There are obviously other perl regeular expressions you could perform on the file as well.
3. Import the table - mysqlimport -u user -p database table < dump.sql

If you want to make sure the string isn't elsewhere in your dataset, run a few regular expressions to make sure they all occur in a similar environment. It's also not that tough to create a backup before you run a replace, in case you accidentally destroy something that loses depth of information.

Note: Posted this answer because OP later stated in comments that they need to select the last two elements, not just the second to last one.

The :nth-child CSS3 selector is in fact more capable than you ever imagined!

For example, this will select the last 2 elements of #container:

#container :nth-last-child(-n+2) {}

But this is just the beginning of a beautiful friendship.

• :nth-child Browser Support

#container :nth-last-child(-n+2) {
  background-color: cyan;
}

<div id="container">
 <div>a</div>
 <div>b</div>
 <div>SELECT THIS</div>
 <div>SELECT THIS</div>
</div>

@InjectMocks
private MyTestObject testObject;

@Mock
private MyDependentObject mockedObject;

@Before
public void setup() {
        MockitoAnnotations.initMocks(this);
}

This will inject any mocked objects into the test class. In this case it will inject mockedObject into the testObject. This was mentioned above but here is the code.

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").

From the command line, you can type

python setup.py --help

...to get a list of commands. What you are looking to do is...

python setup.py install

Instead of NOW() you can use UNIX_TIMESTAMP() also:

$update_query = "UPDATE db.tablename 
                 SET insert_time=UNIX_TIMESTAMP()
                 WHERE username='$somename'";

Difference between UNIX_TIMESTAMP and NOW() in MySQL

Try this :-

try{
        String valuee="25/04/2013";
        Date currentDate =new SimpleDateFormat("dd/MM/yyyy").parse(valuee);
        System.out.println("Date is ::"+currentDate);
        }catch(Exception e){
            System.out.println("Error::"+e);
            e.printStackTrace();
        }

Output:-

   Date is ::Thu Apr 25 00:00:00 GMT+05:30 2013

Your value should be proper format.

In your question also you have asked for this below :-

   Date currentDate = new Date(value);

This style of date constructor is already deprecated.So, its no more use.Being we know that Date has 6 constructor.Read more

Works fine:

var obj = document.createElement('div');
obj.id = "::img";
obj.style.cssText = 'position:absolute;top:300px;left:300px;width:200px;height:200px;-moz-border-radius:100px;border:1px  solid #ddd;-moz-box-shadow: 0px 0px 8px  #fff;display:none;';

document.getElementById("divInsteadOfDocument.Write").appendChild(obj);

You can also see how to set the the CSS in one go (using element.style.cssText).

I suggest you use some more meaningful variable names and don't use the same name for different elements. It looks like you are using obj for different elements (overwriting the value in the function) and this can be confusing.

Use the getResourceAsStream() method on the ServletContext object, e.g.

servletContext.getResourceAsStream("/WEB-INF/myfile");

How you get a reference to the ServletContext depends on your application... do you want to do it from a Servlet or from a JSP?

EDITED: If you're inside a Servlet object, then call getServletContext(). If you're in JSP, use the predefined variable application.

Update: The JSESSIONID stuff here is only for older containers. Please use jt's currently accepted answer unless you are using < Tomcat 6.0.19 or < Tomcat 5.5.28 or another container that does not support HttpOnly JSESSIONID cookies as a config option.

When setting cookies in your app, use

response.setHeader( "Set-Cookie", "name=value; HttpOnly");

However, in many webapps, the most important cookie is the session identifier, which is automatically set by the container as the JSESSIONID cookie.

If you only use this cookie, you can write a ServletFilter to re-set the cookies on the way out, forcing JSESSIONID to HttpOnly. The page at http://keepitlocked.net/archive/2007/11/05/java-and-httponly.aspx http://alexsmolen.com/blog/?p=16 suggests adding the following in a filter.

if (response.containsHeader( "SET-COOKIE" )) {
  String sessionid = request.getSession().getId();
  response.setHeader( "SET-COOKIE", "JSESSIONID=" + sessionid 
                      + ";Path=/<whatever>; Secure; HttpOnly" );
} 

but note that this will overwrite all cookies and only set what you state here in this filter.

If you use additional cookies to the JSESSIONID cookie, then you'll need to extend this code to set all the cookies in the filter. This is not a great solution in the case of multiple-cookies, but is a perhaps an acceptable quick-fix for the JSESSIONID-only setup.

Please note that as your code evolves over time, there's a nasty hidden bug waiting for you when you forget about this filter and try and set another cookie somewhere else in your code. Of course, it won't get set.

This really is a hack though. If you do use Tomcat and can compile it, then take a look at Shabaz's excellent suggestion to patch HttpOnly support into Tomcat.

The base of NGLG answer https://stackoverflow.com/a/8811242/6619626 you can use the following function:

type
OurArrayStr=array of string;

function SplitString(DelimeterChars:char;Str:string):OurArrayStr;
var
seg: TStringList;
i:integer;
ret:OurArrayStr;
begin
    seg := TStringList.Create;
    ExtractStrings([DelimeterChars],[], PChar(Str), seg);
    for i:=0 to seg.Count-1 do
    begin
         SetLength(ret,length(ret)+1);
         ret[length(ret)-1]:=seg.Strings[i];
    end;
    SplitString:=ret;
    seg.Free;
end;

It works in all Delphi versions.

After doing some more googling I came across the float package which lets you prevent LaTeX from repositioning the tables.

In the preamble:

\usepackage{float}
\restylefloat{table}

Then for each table you can use the H placement option (e.g. \begin{table}[H]) to make sure it doesn't get repositioned.

you can do this as below in typescript

 const _params = {} as any;

 _params.name ='nazeh abel'

since typescript does not behave like javascript so we have to make the type as any otherwise it won't allow you to assign property dynamically to an object

Yes, there is one here: http://en.wikipedia.org/wiki/Byte_order_mark#Representations_of_byte_order_marks_by_encoding.

Use cURL,

Check if you have it via phpinfo();

And for the code:

function getHtml($url, $post = null) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    if(!empty($post)) {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    } 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

TableExport - The simple, easy-to-implement library to export HTML tables to xlsx, xls, csv, and txt files.

To use this library, simple call the TableExport constructor:

new TableExport(document.getElementsByTagName("table"));

// OR simply

TableExport(document.getElementsByTagName("table"));

// OR using jQuery

$("table").tableExport(); 

Additional properties can be passed-in to customize the look and feel of your tables, buttons, and exported data. See here more info

Here you go:

$(document).ready(function(){
    $('#submenu li').hover(function(){
        $('#carousel').css('background-position', '10px 10px');
    }, function(){
        $('#carousel').css('background-position', '');
    });
});

Use INDIRECT()

=SUM(INDIRECT(<start cell here> & ":" & <end cell here>))

For Kotlin use KTX extension function: (It uses TextWatcher as previous answers)

yourEditText.doOnTextChanged { text, start, count, after -> 
        // action which will be invoked when the text is changing
    }

import core-KTX:

implementation "androidx.core:core-ktx:1.2.0"

grep uses regexes; . means "any character" in a regex. If you want a literal string, use grep -F, fgrep, or escape the . to \..

Don't forget to wrap your string in double quotes. Or else you should use \\.

So, your command would need to be:

grep -r "0\.49" *

or

grep -r 0\\.49 *

or

grep -Fr 0.49 *

I used to read jupiter nb files with this code:

import codecs
import json

f = codecs.open("JupFileName.ipynb", 'r')
source = f.read()

y = json.loads(source)
pySource = '##Python code from jpynb:\n'
for x in y['cells']:
     for x2 in x['source']:
         pySource = pySource + x2
         if x2[-1] != '\n':
            pySource = pySource + '\n'
print(pySource)

The differences between the two, though subtle, are significant:

.closest()

• Begins with the current element
• Travels up the DOM tree until it finds a match for the supplied selector
• The returned jQuery object contains zero or one element

.parents()

• Begins with the parent element
• Travels up the DOM tree to the document's root element, adding each ancestor element to a temporary collection; it then filters that collection based on a selector if one is supplied
• The returned jQuery object contains zero, one, or multiple elements

From jQuery docs

I got tired of dealing with this issue and put the sort direction and sort column in the ViewState....

Ok so I'll combine ghostdog74's answer and the comments, just for fun.

>>> import os
>>> os.stat('c:/pagefile.sys').st_size==0
False

False means a non-empty file.

So let's write a function:

import os

def file_is_empty(path):
    return os.stat(path).st_size==0

it is much simpler than that.

for i in `find *` ; do sed -i -- 's/search string/target string/g' $i; done

find i => will iterate over all the files in the folder and in subfolders.

sed -i => will replace in the files the relevant string if exists.

To get RHEL 7 64-bit to compile gcc 4.8 32-bit programs, you'll need to do two things.

1. Make sure all the 32-bit gcc 4.8 development tools are completely installed:

   sudo yum install glibc-devel.i686 libgcc.i686 libstdc++-devel.i686 ncurses-devel.i686
   

2. Compile programs using the -m32 flag

   gcc pgm.c -m32 -o pgm
   

stolen from here : How to Compile 32-bit Apps on 64-bit RHEL? - I only had to do step 1.

You could also do something like:

String str = "a + b - c * d / e < f > g >= h <= i == j";
String[] arr = str.split("(?<=\\G(\\w+(?!\\w+)|==|<=|>=|\\+|/|\\*|-|(<|>)(?!=)))\\s*");

It handles white spaces and words of variable length and produces the array:

[a, +, b, -, c, *, d, /, e, <, f, >, g, >=, h, <=, i, ==, j]

That is the mode with which you are opening the file. "wb" means that you are writing to the file (w), and that you are writing in binary mode (b).

Check out the documentation for more: clicky

You need to knock your console into raw mode. There is no built-in platform-independent way of getting there. jCurses might be interesting, though.

On a Unix system, this might work:

String[] cmd = {"/bin/sh", "-c", "stty raw </dev/tty"};
Runtime.getRuntime().exec(cmd).waitFor();

For example, if you want to take into account the time between keystrokes, here's sample code to get there.

Accessing data attribute with its own id is bit easy for me.

$("#Id").data("attribute");

function myFunction(){_x000D_
  alert($("#button1").data("sample-id"));_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<button type="button" id="button1" data-sample-id="gotcha!" onclick="myFunction()"> Clickhere </button>

Almost all answers I searched for this issue say that Python on Windows comes with tkinter and tcl already installed, and I had no luck trying to download or install them using pip, or actviestate.com site. I eventually found that when I was installing python using the binary installer, I had unchecked the module related to TCL and tkinter. So, I ran the binary installer again and chose to modify my python version by this time selecting this option. No need to do anything manually then. If you go to your python terminal, then the following commands should show you version of tkinter installed with your Python:

import tkinter
import _tkinter
tkinter._test()

Alternatively, you could write out the number of elements first (as a header) using:

out.writeInt(prices.length);

When you read the file, you first read the header (element count):

int elementCount = in.readInt();

for (int i = 0; i < elementCount; i++) {
     // read elements
}

I also faced this problem and fixed it by removing version part from the XSD name.

http://www.springframework.org/schema/beans/spring-beans-4.2.xsd to http://www.springframework.org/schema/beans/spring-beans.xsd

Versions less XSD's are mapped to the current version of the framework used in the application.

While other answers already fulfilled the question (it's a 3 years old question after all), I'm just gonna add some info, and probably fixed a bit of misunderstanding.

Em, while originally meant as the term for a single 'M' character's width in typography, in digital medium it was shifted to a unit relative to the point size of the typeface (font-size or textSize), in other words it's uses the height of the text, not the width of a single 'M'.

In Android, that means when you specify the ems of a TextView, it uses the said TextView's textSize as the base, excluding the added padding for accents/diacritics. When you set a 16sp TextView's ems to 4, it means its width will be 64sp wide, thus explained @stefan 's comment about why a 10 ems wide EditText is able to fit 17 'M'.

To throw another potential solution into the mix, I had a settings folder as well as a settings.py in my project dir. (I was switching back from environment-based settings files to one file. I have since reconsidered.)

Python was getting confused about whether I wanted to import project/settings.py or project/settings/__init__.py. I removed the settings dir and everything now works fine.

Here's an easier way:

sudo apt-get install maven

More details are here.

It means, when an error happens on the line, it is telling vbscript to continue execution without aborting the script. Sometimes, the On Error follows the Goto label to alter the flow of execution, something like this in a Sub code block, now you know why and how the usage of GOTO can result in spaghetti code:

Sub MySubRoutine()
   On Error Goto ErrorHandler

   REM VB code...

   REM More VB Code...

Exit_MySubRoutine:

   REM Disable the Error Handler!

   On Error Goto 0

   REM Leave....
   Exit Sub

ErrorHandler:

   REM Do something about the Error

   Goto Exit_MySubRoutine
End Sub

I like to add this method, if you are using an edit form, you can use this code to save the changes in your update(Request $request, $id) function:

$post = Post::find($id);    
$post->fill($request->input())->save();

keep in mind that you have to name your inputs with the same column name. The fill() function will do all the work for you :)

Thought to share my helper method for those who can use it:

public static class Sql
{
    public static T Read<T>(DbDataReader DataReader, string FieldName)
    {
        int FieldIndex;
        try { FieldIndex = DataReader.GetOrdinal(FieldName); }
        catch { return default(T); }

        if (DataReader.IsDBNull(FieldIndex))
        {
            return default(T);
        }
        else
        {
            object readData = DataReader.GetValue(FieldIndex);
            if (readData is T)
            {
                return (T)readData;
            }
            else
            {
                try
                {
                    return (T)Convert.ChangeType(readData, typeof(T));
                }
                catch (InvalidCastException)
                {
                    return default(T);
                }
            }
        }
    }
}

Usage:

cmd.CommandText = @"SELECT DISTINCT [SoftwareCode00], [MachineID] 
                    FROM [CM_S01].[dbo].[INSTALLED_SOFTWARE_DATA]";
using (SqlDataReader data = cmd.ExecuteReader())
{
    while (data.Read())
    {
        usedBy.Add(
            Sql.Read<String>(data, "SoftwareCode00"), 
            Sql.Read<Int32>(data, "MachineID"));
    }
}

The helper method casts to any value you like, if it can't cast or the database value is NULL, the result will be null.

The Pixastic library does exactly what you want. However, it will only work on browsers that have canvas support. For those older browsers, you'll either need to:

1. supply a server-side fallback, or
2. tell the user that you're very sorry, but he'll need to get a more modern browser.

Of course, option #2 isn't very user-friendly. However, if your intent is to provide a pure client-only tool and/or you can't support a fallback back-end cropper (e.g. maybe you're writing a browser extension or offline Chrome app, or maybe you can't afford a decent hosting provider that provides image manipulation libraries), then it's probably fair to limit your user base to modern browsers.

EDIT: If you don't want to learn Pixastic, I have added a very simple cropper on jsFiddle here. It should be possible to modify and integrate and use the drawCroppedImage function with Jcrop.

Here's a complete working example based on your testing. Compare it to what you have currently to figure out where you are going wrong.

If you use jQuery

In case you use jQuery on the client side, you may be interested in this blog post that provides code how to globally extend jQuery's $.parseJSON() function to automatically convert dates for you.

You don't have to change existing code in case of adding this code. It doesn't affect existing calls to $.parseJSON(), but if you start using $.parseJSON(data, true), dates in data string will be automatically converted to Javascript dates.

It supports Asp.net date strings: /Date(2934612301)/ as well as ISO strings 2010-01-01T12_34_56-789Z. The first one is most common for most used back-end web platform, the second one is used by native browser JSON support (as well as other JSON client side libraries like json2.js).

Anyway. Head over to blog post to get the code. http://erraticdev.blogspot.com/2010/12/converting-dates-in-json-strings-using.html

The answer may depend on the target OS. For example, at least one RTOS implementation I'm familiar with will allow multiple sequential "get" operations against a single OS mutex, so long as they're all from within the same thread context. The multiple gets must be replaced by an equal number of puts before another thread will be allowed to get the mutex. This differs from binary semaphores, for which only a single get is allowed at a time, regardless of thread contexts.

The idea behind this type of mutex is that you protect an object by only allowing a single context to modify the data at a time. Even if the thread gets the mutex and then calls a function that further modifies the object (and gets/puts the protector mutex around its own operations), the operations should still be safe because they're all happening under a single thread.

{
    mutexGet();  // Other threads can no longer get the mutex.

    // Make changes to the protected object.
    // ...

    objectModify();  // Also gets/puts the mutex.  Only allowed from this thread context.

    // Make more changes to the protected object.
    // ...

    mutexPut();  // Finally allows other threads to get the mutex.
}

Of course, when using this feature, you must be certain that all accesses within a single thread really are safe!

I'm not sure how common this approach is, or whether it applies outside of the systems with which I'm familiar. For an example of this kind of mutex, see the ThreadX RTOS.

This might be an alternative solution. Paste the following code into the new module:

Public Function ModDate()
ModDate = 
Format(FileDateTime(ThisWorkbook.FullName), "m/d/yy h:n ampm") 
End Function

Before saving your module, make sure to save your Excel file as Excel Macro-Enabled Workbook.

Paste the following code into the cell where you want to display the last modification time:

=ModDate()

I'd also like to recommend an alternative to Excel allowing you to add creation and last modification time easily. Feel free to check on RowShare and this article I wrote: https://www.rowshare.com/blog/en/2018/01/10/Displaying-Last-Modification-Time-in-Excel

You can use generator expressions like this:

gen = (x for x in xyz if x not in a)

for x in gen:
    print x

std::hex is defined in <ios> which is included by <iostream>. But to use things like std::setprecision/std::setw/std::setfill/etc you have to include <iomanip>.

Razor is a view engine for ASP.NET MVC, and also a template engine. Razor code and ASP.NET inline code (code mixed with markup) both get compiled first and get turned into a temporary assembly before being executed. Thus, just like C# and VB.NET both compile to IL which makes them interchangable, Razor and Inline code are both interchangable.

Therefore, it's more a matter of style and interest. I'm more comfortable with razor, rather than ASP.NET inline code, that is, I prefer Razor (cshtml) pages to .aspx pages.

Imagine that you want to get a Human class, and render it. In cshtml files you write:

<div>Name is @Model.Name</div>

While in aspx files you write:

<div>Name is <%= Human.Name %></div>

As you can see, @ sign of razor makes mixing code and markup much easier.

Primitive data types (such as byte) don't have methods in java, but you can directly do:

int i=rno[0];

public class XYZ extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);

        Calendar c = Calendar.getInstance();
        System.out.println("Current time => "+c.getTime());

        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String formattedDate = df.format(c.getTime());
        // formattedDate have current date/time
        Toast.makeText(this, formattedDate, Toast.LENGTH_SHORT).show();


      // Now we display formattedDate value in TextView
        TextView txtView = new TextView(this);
        txtView.setText("Current Date and Time : "+formattedDate);
        txtView.setGravity(Gravity.CENTER);
        txtView.setTextSize(20);
        setContentView(txtView);
    }

}

Try doing: INSERT INTO table(data, date) VALUES ('$data', now() + interval 1 day)

You can do it like this

var db = require('mongo-lite').connect('mongodb://localhost/test')

Guava has a method to do this for you: double[] Doubles.toArray(Collection<Double>)

This isn't necessarily going to be any faster than just looping through the Collection and adding each Double object to the array, but it's a lot less for you to write.

use ng-bind-html-unsafe

it will apply html with text inside like below:

    <li ng-repeat=" opt in opts" ng-bind-html-unsafe="opt.text" >
        {{ opt.text }}
    </li>

If you are trying to access the variable from another PHP file directly, you can include that file with include() or include_once(), giving you access to that variable. Note that this will include the entire first file in the second file.

A class in HTML means that in order to set attributes to it in CSS, you simply need to add a period in front of it.
For example, the CSS code of that html code may be:

.clear {     height: 50px;     width: 25px; } 

Also, if you, as suggested by abiessu, are attempting to add the CSS clear: both; attribute to the div to prevent anything from floating to the left or right of this div, you can use this CSS code:

.clear {     clear: both; } 

Docker isn't virtualization, as such -- instead, it's an abstraction on top of the kernel's support for different process namespaces, device namespaces, etc.; one namespace isn't inherently more expensive or inefficient than another, so what actually makes Docker have a performance impact is a matter of what's actually in those namespaces.

Docker's choices in terms of how it configures namespaces for its containers have costs, but those costs are all directly associated with benefits -- you can give them up, but in doing so you also give up the associated benefit:

• Layered filesystems are expensive -- exactly what the costs are vary with each one (and Docker supports multiple backends), and with your usage patterns (merging multiple large directories, or merging a very deep set of filesystems will be particularly expensive), but they're not free. On the other hand, a great deal of Docker's functionality -- being able to build guests off other guests in a copy-on-write manner, and getting the storage advantages implicit in same -- ride on paying this cost.
• DNAT gets expensive at scale -- but gives you the benefit of being able to configure your guest's networking independently of your host's and have a convenient interface for forwarding only the ports you want between them. You can replace this with a bridge to a physical interface, but again, lose the benefit.
• Being able to run each software stack with its dependencies installed in the most convenient manner -- independent of the host's distro, libc, and other library versions -- is a great benefit, but needing to load shared libraries more than once (when their versions differ) has the cost you'd expect.

And so forth. How much these costs actually impact you in your environment -- with your network access patterns, your memory constraints, etc -- is an item for which it's difficult to provide a generic answer.

There are tcpdump filters for HTTP GET & HTTP POST (or for both plus message body):

• Run man tcpdump | less -Ip examples to see some examples

• Here’s a tcpdump filter for HTTP GET (GET = 0x47, 0x45, 0x54, 0x20):

  sudo tcpdump -s 0 -A 'tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420'
  

• Here’s a tcpdump filter for HTTP POST (POST = 0x50, 0x4f, 0x53, 0x54):

  sudo tcpdump -s 0 -A 'tcp dst port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354)'
  

• Monitor HTTP traffic including request and response headers and message body (source):

  tcpdump -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
  tcpdump -X -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
  

For more information on the bit-twiddling in the TCP header see: String-Matching Capture Filter Generator (link to Sake Blok's explanation).

You need to handle it via ajax submit.

Something like this:

$(function(){
    $('#subscribe-email-form').on('submit', function(e){
        e.preventDefault();
        $.ajax({
            url: url, //this is the submit URL
            type: 'GET', //or POST
            data: $('#subscribe-email-form').serialize(),
            success: function(data){
                 alert('successfully submitted')
            }
        });
    });
});

A better way would be to use a django form, and then render the following snippet:

<form>
    <div class="modal-body">
        <input type="email" placeholder="email"/>
        <p>This service will notify you by email should any issue arise that affects your plivo service.</p>
    </div>
    <div class="modal-footer">
        <input type="submit" value="SUBMIT" class="btn"/>
    </div>
</form>

via the context - example : {{form}}.

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

What's new in .NET Framework 4 Client Profile RTM explains many of the differences:

When to use NET4 Client Profile and when to use NET4 Full Framework?
NET4 Client Profile:
Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).

NET4 Full framework:
Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes:

• If you are building Server apps. Such as:
  o ASP.Net apps
  o Server-side ASMX based web services
• If you use legacy client scenarios. Such as:
  o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.
  o Use legacy Windows Workflow Foundation 3.0 or 3.5 (WF3.0 , WF3.5)
• If you targeting developer scenarios and need tool such as MSBuild or need access to design assemblies such as System.Design.dll

However, as stated on MSDN, this is not relevant for >=4.5:

Starting with the .NET Framework 4.5, the Client Profile has been discontinued and only the full redistributable package is available. Optimizations provided by the .NET Framework 4.5, such as smaller download size and faster deployment, have eliminated the need for a separate deployment package. The single redistributable streamlines the installation process and simplifies your app's deployment options.

NULL is not guaranteed to be 0 -- its exact value is architecture-dependent. Most major architectures define it to (void*)0.

'\0' will always equal 0, because that is how byte 0 is encoded in a character literal.

I don't remember whether C compilers are required to use ASCII -- if not, '0' might not always equal 48. Regardless, it's unlikely you'll ever encounter a system which uses an alternative character set like EBCDIC unless you're working on very obscure systems.

The sizes of the various types will differ on 64-bit systems, but the integer values will be the same.

Some commenters have expressed doubt that NULL be equal to 0, but not be zero. Here is an example program, along with expected output on such a system:

#include <stdio.h>

int main () {
    size_t ii;
    int *ptr = NULL;
    unsigned long *null_value = (unsigned long *)&ptr;
    if (NULL == 0) {
        printf ("NULL == 0\n"); }
    printf ("NULL = 0x");
    for (ii = 0; ii < sizeof (ptr); ii++) {
        printf ("%02X", null_value[ii]); }
    printf ("\n");
    return 0;
}

That program could print:

NULL == 0
NULL = 0x00000001

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

While the proposed solutions work, I was trying to implement with Full Calendar and it would require over 90 database calls for each view (as it loads current, previous, and next month), which, I wasn't too thrilled about.

I found an recursion library https://github.com/tplaner/When where you simply store the rules in the database and one query to pull all the relevant rules.

Hopefully this will help someone else, as I spent so many hours trying to find a good solution.

Edit: This Library is for PHP

Display line numbers:

:set nu

Stop showing the line numbers:

:set nonu

Its short for :set nonumber

ps. These commands are to be run in normal mode.

Have a look at Java ANPR. Free license plate recognition...

This answer similar to others, but using preferred stringr::str_detect and dplyr rownames_to_column.

Ready

function ready(fn){var d=document;(d.readyState=='loading')?d.addEventListener('DOMContentLoaded',fn):fn();}

Use like

ready(function(){
    //some code
});

For self invoking code

(function(fn){var d=document;(d.readyState=='loading')?d.addEventListener('DOMContentLoaded',fn):fn();})(function(){

    //Some Code here
    //DOM is avaliable
    //var h1s = document.querySelector("h1");

});

Support: IE9+

It is ||, for example:

select 'Mr ' || ename from emp;

The only "interesting" feature I can think of is that 'x' || null returns 'x', not null as you might perhaps expect.

I don't think the order can be guaranteed, otherwise it would be easy enough to slice the second half of Object.entries result and map from there.

The only (very minor) issues with the answers above is that

• there is a lot of unnecessary type conversion between string and number.
• the entries are iterated twice when a single iteration is just as clean and effective.

type StandardEnum = { [id: string]: number | string; [nu: number]: string;}

function enumToList<T extends StandardEnum> (enm: T) : { id: number; description: string }[] {
    return Object.entries(enm).reduce((accum, kv) => {
        if (typeof kv[1] === 'number') {
            accum.push({ id: kv[1], description: kv[0] })
        }
        return accum
    }, []) // if enum is huge, perhaps pre-allocate with new Array(entries.length / 2), however then push won't work, so tracking an index would also be required
}

psql --pset=format=FORMAT

Great for executing queries from command line, e.g.

psql --pset=format=unaligned -c "select bandanavalue from bandana where bandanakey = 'atlassian.confluence.settings';"

Putting it another way:

A complete graph is an undirected graph where each distinct pair of vertices has an unique edge connecting them. This is intuitive in the sense that, you are basically choosing 2 vertices from a collection of n vertices.

nC2 = n!/(n-2)!*2! = n(n-1)/2

This is the maximum number of edges an undirected graph can have. Now, for directed graph, each edge converts into two directed edges. So just multiply the previous result with two. That gives you the result: n(n-1)

Use this function: http://br.php.net/json_decode This will automatically create PHP arrays.

To Create SQL server Store procedure in SQL server management studio

• Expand your database
• Expand programmatically
• Right-click on Stored-procedure and Select "new Stored Procedure"

Now, Write your Store procedure, for example, it can be something like below

USE DatabaseName;  
GO  
CREATE PROCEDURE ProcedureName 
 @LastName nvarchar(50),   
 @FirstName nvarchar(50)   
AS   

SET NOCOUNT ON;  
 
//Your SQL query here, like
Select  FirstName, LastName, Department  
FROM HumanResources.vEmployeeDepartmentHistory  
WHERE FirstName = @FirstName AND LastName = @LastName  
GO  

Where, DatabaseName = name of your database
ProcedureName = name of SP
InputValue = your input parameter value (@LastName and @FirstName) and type = parameter type example nvarchar(50) etc.

Source: Stored procedure in sql server (With Example)

To Execute the above stored procedure you can use sample query as below

EXECUTE ProcedureName @FirstName = N'Pilar', @LastName = N'Ackerman';  

One liner with .apply() method is following:

df['color'] = df['Set'].apply(lambda set_: 'green' if set_=='Z' else 'red')

After that, df data frame looks like this:

>>> print(df)
  Type Set  color
0    A   Z  green
1    B   Z  green
2    B   X    red
3    C   Y    red

After much struggle with this same issue I was able to solve the problem by installing the 32 bit version of the 2010 Access Database Engine. For some reason the 64bit version generates this error...

protected void btnExportExcel_Click(object sender, EventArgs e)
{
    DataTable _datatable = new DataTable();
    for (int i = 0; i < grdReport.Columns.Count; i++)
    {
        _datatable.Columns.Add(grdReport.Columns[i].ToString());
    }
    foreach (GridViewRow row in grdReport.Rows)
    {
        DataRow dr = _datatable.NewRow();
        for (int j = 0; j < grdReport.Columns.Count; j++)
        {
            if (!row.Cells[j].Text.Equals("&nbsp;"))
                dr[grdReport.Columns[j].ToString()] = row.Cells[j].Text;
        }

        _datatable.Rows.Add(dr);
    }
    ExportDataTableToExcel(_datatable);
}

Assuming your Generic List is of type String:

TextWriter tw = new StreamWriter("SavedList.txt");

foreach (String s in Lists.verbList)
   tw.WriteLine(s);

tw.Close();

Alternatively, with the using keyword:

using(TextWriter tw = new StreamWriter("SavedList.txt"))
{
   foreach (String s in Lists.verbList)
      tw.WriteLine(s);
}

They both are indeed synonymous, However i found the small difference between them,

1)You cannot use Int32 while creatingenum

enum Test : Int32
{ XXX = 1   // gives you compilation error
}

enum Test : int
{ XXX = 1   // Works fine
}

2) Int32 comes under System declaration. if you remove using.System you will get compilation error but not in case for int

This is what I am using,

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
Uri.parse("http://maps.google.com/maps?saddr="+latitude_cur+","+longitude_cur+"&daddr="+latitude+","+longitude));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addCategory(Intent.CATEGORY_LAUNCHER );     
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

According to Apple's latest document You need to use

appStoreLink = "https://itunes.apple.com/us/app/apple-store/id375380948?mt=8"  

or

SKStoreProductViewController 

Use this one:

Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")

Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")

With rng.Validation
    .Delete 'delete previous validation
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Formula1:="='" & ws.Name & "'!" & range1.Address
End With

Note that when you're using Dim range1, rng As range, only rng has type of Range, but range1 is Variant. That's why I'm using Dim range1 As Range, rng As Range.
About meaning of parameters you can read is MSDN, but in short:

• Type:=xlValidateList means validation type, in that case you should select value from list
• AlertStyle:=xlValidAlertStop specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.
• in your original code, Operator:= xlBetween is odd. It can be used only if two formulas are provided for validation.
• Formula1:="='" & ws.Name & "'!" & range1.Address for list data validation provides address of list with values (in format =Sheet!A1:A5)

In rails 3 you can access the Rack::Mount::RouteSet object via the Rails.application.routes object, then call recognize on it directly

route, match, params = Rails.application.routes.set.recognize(controller.request)

that gets the first (best) match, the following block form loops over the matching routes:

Rails.application.routes.set.recognize(controller.request) do |r, m, p|
  ... do something here ...
end

once you have the route, you can get the route name via route.name. If you need to get the route name for a particular URL, not the current request path, then you'll need to mock up a fake request object to pass down to rack, check out ActionController::Routing::Routes.recognize_path to see how they're doing it.

There is another way to pass arguments to CreateInstance through named parameters.

Based on that, you can pass a array towards CreateInstance. This will allow you to have 0 or multiple arguments.

public T CreateInstance<T>(params object[] paramArray)
{
  return (T)Activator.CreateInstance(typeof(T), args:paramArray);
}

milliseconds = 12884983  // or x milliseconds
hr = 0
min = 0
sec = 0 
day = 0
while (milliseconds >= 1000) {
  milliseconds = (milliseconds - 1000)
  sec = sec + 1
  if (sec >= 60) min = min + 1
  if (sec == 60) sec = 0
  if (min >= 60) hr = hr + 1
  if (min == 60) min = 0
  if (hr >= 24) {
    hr = (hr - 24)
    day = day + 1
  }
}

I hope that my shorter method will help you

Encapsulation is hiding information.

Abstraction is hiding the functionality details.

Encapsulation is performed by constructing the class. Abstraction is achieved by creating either Abstract Classes or Interfaces on top of your class.

In the example given in the question, we are using the class for its functionality and we don't care about how the device achieves that. So we can say the details of the phone are "abstracted" from us.

Encapsulation is hiding WHAT THE PHONE USES to achieve whatever it does; Abstraction is hiding HOW IT DOES it.-

You can do the same thing with the connection opened just once. Something like this.

for(int i=0; i< dataGridView1.Rows.Count;i++)
  {
    string StrQuery= @"INSERT INTO tableName VALUES (" + dataGridView1.Rows[i].Cells["ColumnName"].Value +", " + dataGridView1.Rows[i].Cells["ColumnName"].Value +");";

  try
  {
      SqlConnection conn = new SqlConnection();
      conn.Open();

          using (SqlCommand comm = new SqlCommand(StrQuery, conn))
          {
              comm.ExecuteNonQuery();
          }
      conn.Close();

  }

Also, depending on your specific scenario you may want to look into binding the grid to the database. That would reduce the amount of manual work greatly: http://www.switchonthecode.com/tutorials/csharp-tutorial-binding-a-datagridview-to-a-database

Here's an alternative in case you need to save the value to a variable:

var _t = $('#c_b :checkbox:checked').map(function() {
    return $(this).val();
});
$('#t').append(_t.join(','));

(map() returns an array, which I find handier than the text in textarea).

Follow these steps :

go to Android Sdk then 'platform-tools' path on your Terminal or Console

(on mac, default path is : /Users/USERNAME/Library/Android/sdk/platform-tools)

To check the SDCards(External and Internal) installed on your device fire these commands :

• 1) ./adb shell (hit return/enter)
• 2) cd -(hit return/enter)

now you will see the list of Directories and files from your android device there you may find /sdcard as well as /storage

• 3) cd /storage (hit return/enter)
• 4) ls (hit return/enter)

you may see sdcard0 (generally sdcard0 is internal storage) and sdcard1 (if External SDCard is present)

• 5) exit (hit return/enter)

to come out of adb shell

• 6) ./adb push '/Users/SML/Documents/filename.zip' /storage/sdcard0/path_to_store/ (hit return/enter)

to copy file

I'd just use zip:

In [1]: from pandas import *

In [2]: def calculate(x):
   ...:     return x*2, x*3
   ...: 

In [3]: df = DataFrame({'a': [1,2,3], 'b': [2,3,4]})

In [4]: df
Out[4]: 
   a  b
0  1  2
1  2  3
2  3  4

In [5]: df["A1"], df["A2"] = zip(*df["a"].map(calculate))

In [6]: df
Out[6]: 
   a  b  A1  A2
0  1  2   2   3
1  2  3   4   6
2  3  4   6   9

It works fine. Did you read the documentation? The string is converted to a regular expression.

. is the special character matching all input characters.

As with any regular expression special character, you escape with a \. You need an additional \ for the Java string escape.

Since XCode 4.3 the location has changed, the simulator can now be found at:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/

You should be able to uninstall it using sc.exe (I think it is included in the Windows Resource Kit) by running the following in an "administrator" command prompt:

sc.exe delete <service name>

where <service name> is the name of the service itself as you see it in the service management console, not of the exe.

You can find sc.exe in the System folder and it needs Administrative privileges to run. More information in this Microsoft KB article.

Alternatively, you can directly call the DeleteService() api. That way is a little more complex, since you need to get a handle to the service control manager via OpenSCManager() and so on, but on the other hand it gives you more control over what is happening.

you can use scrollto(x,y) function to handle the position of scrollbar right to the point that you need to be showed after zooming.for finding the position of mouse use event.clientX and event.clientY. this will help you

As string[] implements IEnumerable

IEnumerable<string> m_oEnum = new string[] {"1","2","3"}

Old question, I know. Disabling the cache facility is not needed and not the best way to manage the problem. By disabling the cache facility the server needs to work harder and generates more traffic. Also the browser and device needs to work harder, especially on mobile devices this could be a problem.

The empty page can be easily solved by using Shift key+reload button at the browser.

The empty page can be a result of:

• a bug in your code
• while testing you served an empty page (you can't remember) that is cached by the browser
• a bug in Safari (if so, please report it to Apple and don't try to fix it yourself)

Try first the Shift keyboard key + reload button and see if the problem still exists and review your code.

We could not uninstall a program, stuck with the "Windows error 2 cannot load Java VM". Added the Java path to the PATH variable, uninstalled and re-installed Java 8, the problem would not go away.

Then I found this solution online and it worked for us on the first shot: - Uninstall Java 8 - Install Java 6

Whatever the reason, with Java 6, the error went away, we uninstalled the program, and re-installed Java 8.

I had the exact same problem. I need the filename so to be able to upload it to a website.

It worked for me, if I changed the intent to PICK. This was tested in AVD for Android 4.4 and in AVD for Android 2.1.

Add permission READ_EXTERNAL_STORAGE :

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Change the Intent :

Intent i = new Intent(
  Intent.ACTION_PICK,
  android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI
  );
startActivityForResult(i, 66453666);

/* OLD CODE
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
  Intent.createChooser( intent, "Select Image" ),
  66453666
  );
*/

I did not have to change my code the get the actual path:

// Convert the image URI to the direct file system path of the image file
 public String mf_szGetRealPathFromURI(final Context context, final Uri ac_Uri )
 {
     String result = "";
     boolean isok = false;

     Cursor cursor = null;
      try { 
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(ac_Uri,  proj, null, null, null);

Two years late, but I have the solution you're looking for. Not intending to take credit form the original author, here's a plugin which I found works exceptionally well for what you need, but gets all possible styles in all browsers, even IE.

Warning: This code generates a lot of output, and should be used sparingly. It not only copies all standard CSS properties, but also all vendor CSS properties for that browser.

jquery.getStyleObject.js:

/*
 * getStyleObject Plugin for jQuery JavaScript Library
 * From: http://upshots.org/?p=112
 */

(function($){
    $.fn.getStyleObject = function(){
        var dom = this.get(0);
        var style;
        var returns = {};
        if(window.getComputedStyle){
            var camelize = function(a,b){
                return b.toUpperCase();
            };
            style = window.getComputedStyle(dom, null);
            for(var i = 0, l = style.length; i < l; i++){
                var prop = style[i];
                var camel = prop.replace(/\-([a-z])/g, camelize);
                var val = style.getPropertyValue(prop);
                returns[camel] = val;
            };
            return returns;
        };
        if(style = dom.currentStyle){
            for(var prop in style){
                returns[prop] = style[prop];
            };
            return returns;
        };
        return this.css();
    }
})(jQuery);

Basic usage is pretty simple, but he's written a function for that as well:

$.fn.copyCSS = function(source){
  var styles = $(source).getStyleObject();
  this.css(styles);
}

Hope that helps.

It looks like you're getting back an array. If it's always going to consist of just one element, you could do this (yes, it's pretty much the same thing as Tomalak's answer):

$.each(result[0], function(key, value){
    console.log(key, value);
});

If you might have more than one element and you'd like to iterate over them all, you could nest $.each():

$.each(result, function(key, value){
    $.each(value, function(key, value){
        console.log(key, value);
    });
});

1. Go to Build -> Generate Signed APK in Android Studio.
2. In the new window appeared, click on Create new... button.
3. Next enter details as like shown below and click OK -> Next.
4. Select the Build Type as release and click Finish button.
5. Wait until APK generated successfully message is displayed as like shown below.
6. Click on Show in Explorer to see the signed APK file.

I found another working solution: add the following line to your app under the onCreate event.

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

My sample Cordova project looks like this:

package com.apps.demo;
import android.os.Bundle;
import android.view.WindowManager;
import org.apache.cordova.*;

public class ScanManActivity extends DroidGap {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        super.loadUrl("http://stackoverflow.com");
    }
}

After that, my app would not go to sleep while it was open. Thanks for the anwer goes to xSus.

I have been getting the same error for long time.

When i changed session debug to true

Session session = Session.getDefaultInstance(props, new GMailAuthenticator("[email protected]", "xxxxx"));
session.setDebug(true);

I got help url https://support.google.com/mail/answer/78754 from console along with javax.mail.AuthenticationFailedException.

From the steps in the link, I followed each steps. When I changed my password with mix of letters, numbers, and symbols to be my surprise the email was generated without authentication exception.

Note: My old password was more less secure.

This sample shows how to read a string from a MemoryStream, in which I've used a serialization (using DataContractJsonSerializer), pass the string from some server to client, and then, how to recover the MemoryStream from the string passed as parameter, then, deserialize the MemoryStream.

I've used parts of different posts to perform this sample.

Hope that this helps.

You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

yum update

helped me out. After I had

wget: symbol lookup error: wget: undefined symbol: psl_latest

You can use CREATE SYNONYM to remote object.

How about redis-cli get KEYNAME | wc -c

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

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

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

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

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

You need to use the css-property font-face to declare your font. Have a look at this fancy site: http://www.font-face.com/

Example:

@font-face {
  font-family: MyHelvetica;
  src: local("Helvetica Neue Bold"),
       local("HelveticaNeue-Bold"),
       url(MgOpenModernaBold.ttf);
  font-weight: bold;
}

Nurik's answer was very helpful, but I couldn't get it to work until I found this. In short, if you're using the compatibility library (eg SupportFragmentManager instead of FragmentManager), the syntax of the XML animation files will be different.

This line of code works for me

$("#datepicker").datepicker("option", "dateFormat", "dd/mm/yy");

you can change the id #datepicker with the class .input-group.date of course

Check out TTTAttributedLabel. It's a drop-in replacement for UILabel that allows you to have mixed font and colors in a single label by setting an NSAttributedString as the text for that label.

You can use format strings to give the output string the format you like.

DateTime dateAndTime = DateTime.Now;
Console.WriteLine(dateAndTime.ToString("dd/MM/yyyy")); // Will give you smth like 25/05/2011

Read more about Custom date and time format strings.

Make sure that your connection charset to MySQL is UTF-8. It often defaults to ISO-8859-1 which means that the MySQL driver will convert the text to ISO-8859-1.

You can set the connection charset with mysql_set_charset, mysqli_set_charset or with the query SET NAMES 'utf-8'

This is the unsorted list and we want is 1234567

list = [3,1,2,5,4,7,6]

def sort(list):
    for i in range(len(list)-1):
        if list[i] > list[i+1]:
            a = list[i]
            list[i] = list[i+1]
            list[i+1] = a
        print(list)       

sort(list)

simplest in simplest method to sort a array. Im using currently bubble sorting that is: it checks first 2 location and moves the smallest number to left so on. "-n"in loop is to avoid the indentation error you will understand it by doing it so.
