Excel's interface for SQL Server queries will not let you have a custom parameters.  A way around this is to create a generic Microsoft Query, then add parameters, then paste your parametorized query in the connection's properties.  Here are the detailed steps for Excel 2010:

1. Open Excel
2. Goto Data tab
3. From the From Other Sources button choose From Microsoft Query
4. The "Choose Data Source" window will appear.  Choose a datasource and click OK.
5. The Query Qizard
1. Choose Column: window will appear.  The goal is to create a generic query. I recommend choosing one column from a small table.
2. Filter Data: Just click Next
3. Sort Order: Just click Next
4. Finish: Just click Finish.
6. The "Import Data" window will appear:
1. Click the Properties... button.
1. Choose the Definition tab
2. In the "Command text:" section add a WHERE clause that includes Excel parameters.  It's important to add all the parameters that you want now.  For example, if I want two parameters I could add this:
   WHERE 1 = ? and 2 = ?
3. Click OK to get back to the "Import Data" window
2. Choose PivotTable Report
3. Click OK
7. You will be prompted to enter the parameters value for each parameter.
8. Once you have enter the parameters you will be at your pivot table
9. Go batck to the Data tab and click the connections Properties button
1. Click the Definition tab
2. In the "Command text:" section, Paste in the real SQL Query that you want with the same number of parameters that you defined earlier.
3. Click the Parameters... button 
1. enter the Prompt values for each parameter
2. Click OK
4. Click OK to close the properties window
10. Congratulations, you now have parameters.

There is no precise meaning, precisely because these terms mean the opposite things depending on whether you are merging or rebasing. THE natural way of thinking about two branches is "my work" and "someone else's work". The choice of terminology that obscures this classification is absolutely THE worst design choice in git. It must have been inspired by accounting's "credit" and "debit" or "assets" and "liabilities" - same headache.

Pro single

• Easy to find.

• Hunting down exclusion rules can be quite difficult if I have multiple gitignore, at several levels in the repo.

• With multiple files, you also typically wind up with a fair bit of duplication.

Pro multiple

• Scopes "knowledge" to the part of the file tree where it is needed.

• Since Git only tracks files, an empty .gitignore is the only way to commit an "empty" directory.

  (And before Git 1.8, the only way to exclude a pattern like my/**.example was to create my/.gitignore in with the pattern **.foo. This reason doesn't apply now, as you can do /my/**/*.example.)

I much prefer a single file, where I can find all the exclusions. I've never missed per-directory .svn, and I won't miss per-directory .gitignore either.

That said, multiple gitignores are quite common. If you do use them, at least be consistent in their use to make them reasonable to work with. For example, you may put them in directories only one level from the root.

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

You don't have that kind of control with a bare a tag. But you can hook up the tag's onclick handler to call window.open(...) with the right parameters. See here for examples: https://developer.mozilla.org/En/DOM/Window.open

I still don't think you can force window over tab directly though-- that depends on the browser and the user's settings.

this works for me :

import groovy.json.JsonBuilder
properties = new Properties()
properties.put("name", "zhangsan")

println new JsonBuilder(properties).toPrettyString()

PermGen space is replaced by MetaSpace in Java 8. The PermSize and MaxPermSize JVM arguments are ignored and a warning is issued if present at start-up.

Most allocations for the class metadata are now allocated out of native memory. * The classes that were used to describe class metadata have been removed.

Main difference between old PermGen and new MetaSpace is, you don't have to mandatory define upper limit of memory usage. You can keep MetaSpace space limit unbounded. Thus when memory usage increases you will not get OutOfMemoryError error. Instead the reserved native memory is increased to full-fill the increase memory usage.

You can define the max limit of space for MetaSpace, and then it will throw OutOfMemoryError : Metadata space. Thus it is important to define this limit cautiously, so that we can avoid memory waste.

In my case when i tried

$ hive --service metastore 

I got

MetaException(message:Version information not found in metastore. )

The necessary tables required for the metastore are missing in MySQL. Manually create the tables and restart hive metastore.

cd $HIVE_HOME/scripts/metastore/upgrade/mysql/ 

< Login into MySQL > 

mysql> drop database IF EXISTS <metastore db name>; 
mysql> create database <metastore db name>; 
mysql> use <metastore db name>; 
mysql> source hive-schema-2.x.x.mysql.sql; 

metastore db name should match the database name mentioned in hive-site.xml files connection property tag.

hive-schema-2.x.x.mysql.sql file depends on the version available in the current directory. Try to go for the latest because it holds many old schema files also.

Now try to execute hive --service metastore If everything goes cool, then simply start the hive from terminal.

>hive

I hope the above answer serves your need.

You can use the 'more' command to see the content of the file:

more filename.txt

Arrays.sort(yourArray)

will do the job perfectly

I use a small set of documentation patterns:

• always documenting about thread-safety
• always documenting immutability
• javadoc with examples (like Formatter)
• @Deprecation with WHY and HOW to replace the annotated element

Use the following query:

SELECT E.I_EmpID AS EMPID,
       E.I_EMPCODE AS EMPCODE,
       E.I_EmpName AS EMPNAME,
       REPLACE(TO_CHAR(A.I_REQDATE, 'DD-Mon-YYYY'), ' ', '') AS FROMDATE,
       REPLACE(TO_CHAR(A.I_ENDDATE, 'DD-Mon-YYYY'), ' ', '') AS TODATE,
       TO_CHAR(NOD) AS NOD,
       DECODE(A.I_DURATION,
              'FD',
              'FullDay',
              'FN',
              'ForeNoon',
              'AN',
              'AfterNoon') AS DURATION,
       L.I_LeaveType AS LEAVETYPE,
       REPLACE(TO_CHAR((SELECT max(C.I_WORKDATE)
                         FROM T_COMPENSATION C
                        WHERE C.I_COMPENSATEDDATE = A.I_REQDATE
                          AND C.I_EMPID = A.I_EMPID),
                       'DD-Mon-YYYY'),
               ' ',
               '') AS WORKDATE,
       A.I_REASON AS REASON,
       AP.I_REJECTREASON AS REJECTREASON
  FROM T_LEAVEAPPLY A
 INNER JOIN T_EMPLOYEE_MS E
    ON A.I_EMPID = E.I_EmpID
   AND UPPER(E.I_IsActive) = 'YES'
   AND A.I_STATUS = '1'
 INNER JOIN T_LeaveType_MS L
    ON A.I_LEAVETYPEID = L.I_LEAVETYPEID
  LEFT OUTER JOIN T_APPROVAL AP
    ON A.I_REQDATE = AP.I_REQDATE
   AND A.I_EMPID = AP.I_EMPID
   AND AP.I_APPROVALSTATUS = '1'
 WHERE E.I_EMPID <> '22'
 ORDER BY A.I_REQDATE DESC

The trick is to force the inner query return only one record by adding an aggregate function (I have used max() here). This will work perfectly as far as the query is concerned, but, honestly, OP should investigate why the inner query is returning multiple records by examining the data. Are these multiple records really relevant business wise?

Here's my short summary.

If you want to write a unit test, don't use a Spring applicationContext because you don't want any real dependencies injected in the class you are unit testing. Instead use mocks, either with the @RunWith(MockitoJUnitRunner.class) annotation on top of the class, or with MockitoAnnotations.initMocks(this) in the @Before method.

If you want to write an integration test, use:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("yourTestApplicationContext.xml")

To set up your application context with an in-memory database for example. Normally you don't use mocks in integration tests, but you could do it by using the MockitoAnnotations.initMocks(this) approach described above.

You can view the java doc examples or the example of usage of Predicate here

Basically it is used to filter rows in the resultset based on any specific criteria that you may have and return true for those rows that are meeting your criteria:

 // the age column to be between 7 and 10
    AgeFilter filter = new AgeFilter(7, 10, 3);

    // set the filter.
    resultset.beforeFirst();
    resultset.setFilter(filter);

You can try in this way. I had applied this in my case.

#include<stdio.h>

struct name
{

  char first[20];

  char last[30];

};

//globally

// struct name sara={"Sara","Black"};

int main()

 {

//locally

struct name sara={"Sara","Black"};


printf("%s",sara.first);

printf("%s",sara.last);

}

The best way to convert it to HashMap<String, Object> is this:

HashMap<String, Object> result = new ObjectMapper().readValue(jsonString, new TypeReference<Map<String, Object>>(){}));

I found a fairly robust solution at https://gallery.technet.microsoft.com/scriptcenter/c0c57332-8624-48c0-b4c3-5b31fe641c58 , which I thought was worth pointing out. It searches columns of these types: varchar, char, nvarchar, nchar, text. It works great and supports specific table-searching as well as multiple search-terms.

A method is not (yet) a first-class object in Java; you can't pass a function pointer as a callback. Instead, create an object (which usually implements an interface) that contains the method you need and pass that.

Proposals for closures in Java—which would provide the behavior you are looking for—have been made, but none will be included in the upcoming Java 7 release.

This is how I was able to trigger a button click when the page loads.

<li ng-repeat="a in array">
  <a class="button" id="btn" ng-click="function(a)" index="$index" on-load-clicker>
    {{a.name}}
  </a>
</li>

A simple directive that takes the index from the ng-repeat and uses a condition to call the first button in the index and click it when the page loads.

angular
    .module("myApp")
        .directive('onLoadClicker', function ($timeout) {
            return {
                restrict: 'A',
                scope: {
                    index: '=index'
                },
                link: function($scope, iElm) {
                    if ($scope.index == 0) {
                        $timeout(function() {

                            iElm.triggerHandler('click');

                        }, 0);
                    }
                }
            };
        });

This was the only way I was able to even trigger an auto click programmatically in the first place. angular.element(document.querySelector('#btn')).click(); Did not work from the controller so making this simple directive seems most effective if you are trying to run a click on page load and you can specify which button to click by passing in the index. I got help through this stack-overflow answer from another post reference: https://stackoverflow.com/a/26495541/4684183 onLoadClicker Directive.

A IMHO more minimal snippet (that also more narrowly scopes the length variable):

byte[] buffer = new byte[2048];
for (int n = in.read(buffer); n >= 0; n = in.read(buffer))
    out.write(buffer, 0, n);

As a side note, I don't understand why more people don't use a for loop, instead opting for a while with an assign-and-test expression that is regarded by some as "poor" style.

This should work

DECLARE @singleQuote CHAR 
SET @singleQuote =  CHAR(39)

insert into my_table values('hi, my name'+ @singleQuote +'s tim.')

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

If none of the methods help try checking your system and user environments PATH and PYTHONPATH variables.

I was getting this error due to my PATH variable was pointing to different Python installation (which comes from ArcGIS Desktop).

After removing path to my Python installation from PATH variable and completely removing PYTHONPATH variable, I got it working!

Keep in mind that python command will not be available from command line if you remove it from PATH.

Normal answer for this question if you really want to get something like content//media/external/video/media/18576 (e.g. for your video mp4 absolute path) and not just file///storage/emulated/0/DCIM/Camera/20141219_133139.mp4:

MediaScannerConnection.scanFile(this,
          new String[] { file.getAbsolutePath() }, null,
          new MediaScannerConnection.OnScanCompletedListener() {
      public void onScanCompleted(String path, Uri uri) {
          Log.i("onScanCompleted", uri.getPath());
      }
 });

Accepted answer is wrong (cause it will not return content//media/external/video/media/*)

Uri.fromFile(file).toString() only returns something like file///storage/emulated/0/* which is a simple absolute path of a file on the sdcard but with file// prefix (scheme)

You can also get content uri using MediaStore database of Android

TEST (what returns Uri.fromFile and what returns MediaScannerConnection):

File videoFile = new File("/storage/emulated/0/video.mp4");

Log.i(TAG, Uri.fromFile(videoFile).toString());

MediaScannerConnection.scanFile(this, new String[] { videoFile.getAbsolutePath() }, null,
        (path, uri) -> Log.i(TAG, uri.toString()));

Output:

I/Test: file:///storage/emulated/0/video.mp4

I/Test: content://media/external/video/media/268927

I was getting this exception not because of AND instead of comma, in fact I was having this exception just because I was not using apostrophes in where clause.

Like my query was

update table set coulmn1='something' where column2 in (00012121);

when I changed where clause to where column2 in ('00012121'); then the query worked fine for me.

I used this:

HTMLDatetoIsoDate(htmlDate){
  let year = Number(htmlDate.toString().substring(0, 4))
  let month = Number(htmlDate.toString().substring(5, 7))
  let day = Number(htmlDate.toString().substring(8, 10))
  return new Date(year, month - 1, day)
}

isoDateToHtmlDate(isoDate){
  let date = new Date(isoDate);
  let dtString = ''
  let monthString = ''
  if (date.getDate() < 10) {
    dtString = '0' + date.getDate();
  } else {
    dtString = String(date.getDate())
  }
  if (date.getMonth()+1 < 10) {
    monthString = '0' + Number(date.getMonth()+1);
  } else {
    monthString = String(date.getMonth()+1);
  }
  return date.getFullYear()+'-' + monthString + '-'+dtString
}

In many programming languages, the Boolean type is, or is implemented as, a subtype of integer, where true behaves like 1 and false behaves like 0:

• Boolean in C

• Boolean in Python

• Boolean in Java

Mathematically, Boolean algebra resembles integer arithmetic modulo 2. Therefore, if a language doesn't provide native Boolean type, the most natural and efficient solution is to use integers. This works with almost any language. For example, in Bash you can do:

# val=1; ((val)) && echo "true" || echo "false"
true
# val=0; ((val)) && echo "true" || echo "false"
false

man bash:

((expression))

The expression is evaluated according to the rules described below under ARITHMETIC EVALUATION. If the value of the expression is non-zero, the return status is 0; otherwise the return status is 1. This is exactly equivalent to let "expression".

You don't need to write a converter, just do this in your handler/codebehind:

int i = Convert.ToInt32(txtMyTextBox.Text);

OR

int i = int.Parse(txtMyTextBox.Text);

The Text property of your textbox is a String type, so you have to perform the conversion in the code.

This covers: Decimal part control (including number of decimals allowed), copy/paste control, international separators.

Steps:

1. Make sure your view controller inherits from UITextFieldDelegate

   class MyViewController: UIViewController, UITextFieldDelegate {...

2. In viewDidLoad, set your control delegate to self:

   override func viewDidLoad() { super.viewDidLoad(); yourTextField.delegate = self }

3. Implement the following method and update the "decsAllowed" constant with the desired amount of decimals or 0 if you want a natural number.

Swift 4

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    let decsAllowed: Int = 2
    let candidateText = NSString(string: textField.text!).replacingCharacters(in: range, with: string)
    let decSeparator: String = NumberFormatter().decimalSeparator!;

    let splitted = candidateText.components(separatedBy: decSeparator)
    let decSeparatorsFound = splitted.count - 1
    let decimalPart = decSeparatorsFound > 0 ? splitted.last! : ""
    let decimalPartCount = decimalPart.characters.count

    let characterSet = NSMutableCharacterSet.decimalDigit()
    if decsAllowed > 0 {characterSet.addCharacters(in: decSeparator)}

    let valid = characterSet.isSuperset(of: CharacterSet(charactersIn: candidateText)) &&
                decSeparatorsFound <= 1 &&
                decsAllowed >= decimalPartCount

    return valid
}

If afterwards you need to safely convert that string into a number, you can just use Double(yourstring) or Int(yourstring) type cast, or the more academic way:

let formatter = NumberFormatter()
let theNumber: NSNumber = formatter.number(from: yourTextField.text)!

. matches any character so needs escaping i.e. \., or \\. within a Java string (because \ itself has special meaning within Java strings.)

You can then use \.\. or \.{2} to match exactly 2 dots.

You can use optimizer hints

select /*+ INDEX(table_name index_name) */ from table etc...

More on using optimizer hints: http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/hintsref.htm

Wow you're close. Edits in comments:

function add(type) {_x000D_
  //Create an input type dynamically.   _x000D_
  var element = document.createElement("input");_x000D_
  //Assign different attributes to the element. _x000D_
  element.type = type;_x000D_
  element.value = type; // Really? You want the default value to be the type string?_x000D_
  element.name = type; // And the name too?_x000D_
  element.onclick = function() { // Note this is a function_x000D_
    alert("blabla");_x000D_
  };_x000D_
_x000D_
  var foo = document.getElementById("fooBar");_x000D_
  //Append the element in page (in span).  _x000D_
  foo.appendChild(element);_x000D_
}_x000D_
document.getElementById("btnAdd").onclick = function() {_x000D_
  add("text");_x000D_
};

<input type="button" id="btnAdd" value="Add Text Field">_x000D_
<p id="fooBar">Fields:</p>

Now, instead of setting the onclick property of the element, which is called "DOM0 event handling," you might consider using addEventListener (on most browsers) or attachEvent (on all but very recent Microsoft browsers) — you'll have to detect and handle both cases — as that form, called "DOM2 event handling," has more flexibility. But if you don't need multiple handlers and such, the old DOM0 way works fine.

Separately from the above: You might consider using a good JavaScript library like jQuery, Prototype, YUI, Closure, or any of several others. They smooth over browsers differences like the addEventListener / attachEvent thing, provide useful utility features, and various other things. Obviously there's nothing a library can do that you can't do without one, as the libraries are just JavaScript code. But when you use a good library with a broad user base, you get the benefit of a huge amount of work already done by other people dealing with those browsers differences, etc.

template<class Tag>using type_t=typename Tag::type;

the above helpers let you work with types as values.

class A {
  template<class T>
  A( tag<T> );
};

the tag<T> type is a variable with no state besides the type it caries. You can use this to pass a pure-type value into a template function and have the type be deduced by the template function:

auto a = A(tag<int>{});

You can pass in more than one type:

class A {
  template<class T, class U, class V>
  A( types<T,U,V> );
};
auto a = A(types<int,double,std::string>{});

Try,

  string[] files =  new DirectoryInfo(dir).GetFiles().Select(o => o.Name).ToArray();

You can use the following methods to update the value of a reactive form control. Any of the following method will suit for your need.

Methods using setValue()

this.form.get("dept").setValue(selected.id);
this.form.controls["dept"].setValue(selected.id);

Methods using patchValue()

this.form.get("dept").patchValue(selected.id);
this.form.controls['dept'].patchValue(selected.id);
this.form.patchValue({"dept": selected.id});

Last method will loop thorough all the controls in the form so it is not preferred when updating single control

You can use any of the method inside the event handler

deptSelected(selected: { id: string; text: string }) {
     // any of the above method can be added here
}

You can update multiple controls in the form group if required using the

this.form.patchValue({"dept": selected.id, "description":"description value"});

The -i option is the one that you want:

curl -i http://localhost

-i, --include Include protocol headers in the output (H/F)

Alternatively you can use the verbose option:

curl -v http://localhost

-v, --verbose Make the operation more talkative

I found the solution myself later, so I placed it as an answer:

The error persisted every now and then when adding new function to my JS file. I ultimately stripped down my concatenated JS file and found out that there were two versions of jQuery being loaded, of which one was very, very old.

On my Linux machine :

git config --system --get https.proxy (returns nothing)
git config --global --get https.proxy (returns nothing)

git config --system --get http.proxy (returns nothing)
git config --global --get http.proxy (returns nothing)

I found out my https_proxy and http_proxy are set, so I just unset them.

unset https_proxy
unset http_proxy

On my Windows machine :

set https_proxy=""
set http_proxy=""

Optionally use setx to set environment variables permanently on Windows and set system environment using "/m"

setx https_proxy=""
setx http_proxy=""

you can multiplication using lambda

foo=[1,2,3,4]
bar=[1,2,5,55]
l=map(lambda x,y:x*y,foo,bar)

Here is my class, works like a charm :

public static class IniFileManager

    [DllImport("kernel32")]
    private static extern long WritePrivateProfileString(string section,
        string key, string val, string filePath);
    [DllImport("kernel32")]
    private static extern int GetPrivateProfileString(string section,
             string key, string def, StringBuilder retVal,
        int size, string filePath);
    [DllImport("kernel32.dll")]
    private static extern int GetPrivateProfileSection(string lpAppName,
             byte[] lpszReturnBuffer, int nSize, string lpFileName);


    /// <summary>
    /// Write Data to the INI File
    /// </summary>

    /// Section name
    /// <PARAM name="Key"></PARAM>
    /// Key Name
    /// <PARAM name="Value"></PARAM>
    /// Value Name
    public static void IniWriteValue(string sPath,string Section, string Key, string Value)
    {
        WritePrivateProfileString(Section, Key, Value, sPath);
    }

    /// <summary>
    /// Read Data Value From the Ini File

    /// <returns></returns>
    public static string IniReadValue(string sPath,string Section, string Key)
    {
        StringBuilder temp = new StringBuilder(255);
        int i = GetPrivateProfileString(Section, Key, "", temp,
                                        255, sPath);
        return temp.ToString();

    }

}

The use is obviouse since its a static class, just call IniFileManager.IniWriteValue for readsing a section or IniFileManager.IniReadValue for reading a section.

I was looking through a ton of java code for a specific library: car.csclh.server.isr.businesslogic.TypePlatform (although I only knew car and Platform at the time). Unfortunately, none of the other suggestions here worked for me, so I figured I'd post this.

Here's the regex I used to find it:

\bcar\..*Platform

After careful consideration this dillema has a few different solutions:

Aggregate Everything Use an aggregate on each column to get the biggest or smallest field value. This is what I am doing since it takes 2 partially filled out records and "merges" the data.

http://sqlfiddle.com/#!3/59cde/1

SELECT
  UPPER(IDNo) AS user_id
, MAX(FirstName) AS name_first
, MAX(LastName) AS name_last
, MAX(entry) AS row_num
FROM people P
GROUP BY 
  IDNo

Get First (or Last record)

http://sqlfiddle.com/#!3/59cde/23

-- ------------------------------------------------------
-- Notes
-- entry: Auto-Number primary key some sort of unique PK is required for this method
-- IDNo:  Should be primary key in feed, but is not, we are making an upper case version
-- This gets the first entry to get last entry, change MIN() to MAX()
-- ------------------------------------------------------

SELECT 
   PC.user_id
  ,PData.FirstName
  ,PData.LastName
  ,PData.entry
FROM (
  SELECT 
      P2.user_id
     ,MIN(P2.entry) AS rownum
  FROM (
    SELECT
        UPPER(P.IDNo) AS user_id 
      , P.entry 
    FROM people P
  ) AS P2
  GROUP BY 
    P2.user_id
) AS PC
LEFT JOIN people PData
ON PData.entry = PC.rownum
ORDER BY 
   PData.entry

A really simple solution is just to edit the $state.current.name string and cut out everything including and after the last '.' - you get the name of the parent state. This doesn't work if you jump a lot between states because it just parses back the current path. But if your states correspond to where you actually are, then this works.

var previousState = $state.current.name.substring(0, $state.current.name.lastIndexOf('.'))
$state.go(previousState)

This also works with maven by defining the resources tag. You can name your src folder names whatever you like.

    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.java</include>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
        </resource>

        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.java</include>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
        </resource>

        <resource>
            <directory>src/main/generated</directory>
            <includes>
                <include>**/*.java</include>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
        </resource>
    </resources>

I'd have a class in your CSS like this:

.no-transition { 
  -webkit-transition: none;
  -moz-transition: none;
  -o-transition: none;
  -ms-transition: none;
  transition: none;
}

and then in your jQuery:

$('#elem').addClass('no-transition'); //will disable it
$('#elem').removeClass('no-transition'); //will enable it

Use re.escape

>>> import re
>>> re.escape(r'\ a.*$')
'\\\\\\ a\\.\\*\\$'
>>> print(re.escape(r'\ a.*$'))
\\\ a\.\*\$
>>> re.escape('www.stackoverflow.com')
'www\\.stackoverflow\\.com'
>>> print(re.escape('www.stackoverflow.com'))
www\.stackoverflow\.com

Repeating it here:

re.escape(string)

Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

As of Python 3.7 re.escape() was changed to escape only characters which are meaningful to regex operations.

Collection.count no bracket

{% if request.user.is_authenticated %}
{{wishlists.count}}
{% else %}0{% endif %}

When I was using the below command, I too was getting the same error:

node .function-hello.js

I changed my command to below command, it worked fine:

node .\function-hello.js

First, describe nodes and see if it reports anything:

$ kubectl describe nodes

Look for conditions, capacity and allocatable:

Conditions:
  Type              Status
  ----              ------
  OutOfDisk         False
  MemoryPressure    False
  DiskPressure      False
  Ready             True
Capacity:
 cpu:       2
 memory:    2052588Ki
 pods:      110
Allocatable:
 cpu:       2
 memory:    1950188Ki
 pods:      110

If everything is alright here, SSH into the node and observe kubelet logs to see if it reports anything. Like certificate erros, authentication errors etc.

If kubelet is running as a systemd service, you can use

$ journalctl -u kubelet

In order to get the values of your parameters, you can use RouteData.

More context would be nice. Why do you need to "extract" them in the first place? You should have an Action like:

public ActionResult Edit(int id, bool allowed) {}

You are correct. You did exactly the right thing, checking the query plan rather than trying to second-guess the optimiser. :-)

If you abstract the chat server up a level, then you get the answer.

Akka provides a messaging system that is akin to Erlang's "let it crash" mentality.

So examples are things that need varying levels of durability and reliability of messaging:

• Chat server
• Network layer for an MMO
• Financial data pump
• Notification system for an iPhone/mobile/whatever app
• REST Server
• Maybe something akin to WebMachine (guess)

The nice things about Akka are the choices it affords for persistence, it's STM implementation, REST server and fault-tolerance.

Don't get annoyed by the example of a chat server, think of it as an example of a certain class of solution.

With all their excellent documentation, I feel like a gap is this exact question, use-cases and examples. Keeping in mind the examples are non-trivial.

(Written with only experience of watching videos and playing with the source, I have implemented nothing using akka.)

I think that in real world scenarios a simple click handler is probably better than over-complicated command-based systems but you can do something like that:

using RelayCommand from this article http://msdn.microsoft.com/en-us/magazine/dd419663.aspx

public class MyCommands
{
    public static readonly ICommand CloseCommand =
        new RelayCommand( o => ((Window)o).Close() );
}

<Button Content="Close Window"
        Command="{X:Static local:MyCommands.CloseCommand}"
        CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, 
                           AncestorType={x:Type Window}}}"/>

Tried it with CSS, but its never 100% responsive, so I built a pure javascript solution. This one uses jQuery,

google.maps.event.addDomListener(window, "resize", function() {

  var center = map.getCenter();

  resizeMap();

  google.maps.event.trigger(map, "resize");
  map.setCenter(center);

});



function resizeMap(){

  var h = window.innerHeight;
  var w = window.innerWidth;

  $("#map_canvas").width(w/2);
  $("#map_canvas").height(h-50);

}

This question has more than 30 answers already. I am going to summarize and explain them (with a "my father" analogy) and add my suggested solution.

You have 4+1 classes of solutions:

1) Use a hacky incomplete quick one-liner

Good if you are in a rush and 99% correctness works.

Examples of this is, JSON.stringify() suggested by Pratik Bhalodiya, or JSON.encode by Joel Anair, or .toString(), or other methods that transform your objects into a String and then compare the two Strings using === character by character.

The drawback, however, is that there is no globally standard unique representation of an Object in String. e.g. { a: 5, b: 8} and {b: 8 and a: 5 } are equal.

• Pros: Fast, quick.
• Cons: Hopefully works! It will not work if the environment/browser/engine memorizes the ordering for objects (e.g. Chrome/V8) and the order of the keys are different (Thanks to Eksapsy.) So, not guaranteed at all. Performance wouldn't be great either in large objects.

My Father Analogy

When I am talking about my father, "my tall handsome father" and "my handsome tall father" are the same person! But the two strings are not the same.

Note that there is actually a correct (standard way) order of adjectives in English grammar, which says it should be a "handsome tall man," but you are risking your competency if you blindly assume Javascript engine of iOS 8 Safari is also abiding the same grammar, blindly! #WelcomeToJavascriptNonStandards

2) Write your own DIY recursive function

Good if you are learning.

Examples are atmin's solution.

The biggest disadvantage is you will definitely miss some edge cases. Have you considered a self-reference in object values? Have you considered NaN? Have you considered two objects that have the same ownProperties but different prototypical parents?

I would only encourage people to do this if they are practicing and the code is not going to go in production. That's the only case that reinventing the wheel has justifications.

• Pros: Learning opportunity.
• Cons: Not reliable. Takes time and concerns.

My Father Analogy

It's like assuming if my dad's name is "John Smith" and his birthday is "1/1/1970", then anyone whose name is "John Smith" and is born on "1/1/1970" is my father.

That's usually the case, but what if there are two "John Smith"s born on that day? If you think you will consider their height, then that's increasing the accuracy but still not a perfect comparison.

2.1 You limited scope DIY comparator

Rather than going on a wild chase of checking all the properties recursively, one might consider checking only "a limited" number of properties. For instance, if the objects are Users, you can compare their emailAddress field.

It's still not a perfect one, but the benefits over solution #2 are:

1. It's predictable, and it's less likely to crash.
2. You are driving the "definition" of equality, rather than relying on a wild form and shape of the Object and its prototype and nested properties.

3) Use a library version of equal function

Good if you need a production-level quality, and you cannot change the design of the system.

Examples are _.equal of lodash, already in coolaj86's answer or Angular's or Ember's as mentioned in Tony Harvey's answer or Node's by Rafael Xavier.

• Pros: It's what everyone else does.
• Cons: External dependency, which can cost you extra memory/CPU/Security concerns, even a little bit. Also, can still miss some edge cases (e.g. whether two objects having same ownProperties but different prototypical parents should be considered the same or not.) Finally, you might be unintentionally band-aiding an underlying design problem with this; just saying!

My Father Analogy

It's like paying an agency to find my biological father, based on his phone, name, address, etc.

It's gonna cost more, and it's probably more accurate than myself running the background check, but doesn't cover edge cases like when my father is immigrant/asylum and his birthday is unknown!

4) Use an IDentifier in the Object

Good if you [still] can change the design of the system (objects you are dealing with) and you want your code to last long.

It's not applicable in all cases, and might not be very performant. However, it's a very reliable solution, if you can make it.

The solution is, every object in the system will have a unique identifier along with all the other properties. The uniqueness of the identifier will be guaranteed at the time of generation. And you will use this ID (also known as UUID/GUID -- Globally/Universally Unique Identifier) when it comes to comparing two objects. i.e. They are equal if and only if these IDs are equal.

The IDs can be simple auto_incremental numbers, or a string generated via a library (advised) or a piece of code. All you need to do is make sure it's always unique, which in case of auto_incremental it can be built-in, or in case of UUID, can be checked will all existing values (e.g. MySQL's UNIQUE column attribute) or simply (if coming from a library) be relied upon giving the extremely low likelihood of a collision.

Note that you also need to store the ID with the object at all times (to guarantee its uniqueness), and computing it in real-time might not be the best approach.

• Pros: Reliable, efficient, not dirty, modern.
• Cons: Needs extra space. Might need a redesign of the system.

My Father Analogy

It's like known my father's Social Security Number is 911-345-9283, so anyone who has this SSN is my father, and anyone who claims to be my father must have this SSN.

Conclusion

I personally prefer solution #4 (ID) over them all for accuracy and reliability. If it's not possible I'd go with #2.1 for predictability, and then #3. If neither is possible, #2 and finally #1.

Create a file named .gitignore in your project's directory. Ignore directories by entering the directory name into the file (with a slash appended):

dir_to_ignore/

More information is here.

At the beginning of the file you are compiling, before any include, try to put ONE of these lines

#define _X86_
#define _AMD64_
#define _ARM_

Choose the appropriate, only one, depending on your architecture.

it was hard to solve but i did it look go to C:\Users\Vinnie\ delete .gradle file its you didn't see it it may be in hidden files so if you use windows 7 right click then click on properties and click on hidden to be not checked

then the file will appear then delete it i hope this works

You could do it in either of this ways , triggering an onclick on a form button like this,

<form id="myform" name="myform" method="post" action="demo2.jsp">
    <input type="text"  name="usnername" />
    <input type="text" name="password"/>        
    <input type="button" value="go" onclick="submitForm" />
</form>

And using javascript,

        function submitForm() {                
            document.forms[0].submit();
            return true;
        }

or you could also try Ajax to post your page

here is the link jQueryAjax

And also nice startup examples using Ajax and here

Hope this helps !!

Bugs caused by missing predefined folder for store compiled class file which is normally is /out folder by default. You can give a try to close Intellij > Import Project > From existing source. This will solve this problem.

Complate Angular Way ( Set/Get value by Id ):

// In Html tag

 <button (click) ="setValue()">Set Value</button>
 <input type="text"  #userNameId />

// In component .ts File

    export class testUserClass {
       @ViewChild('userNameId') userNameId: ElementRef;

      ngAfterViewInit(){
         console.log(this.userNameId.nativeElement.value );
       }

      setValue(){
        this.userNameId.nativeElement.value = "Sample user Name";
      }



   }

CHARINDEX() searches for a substring within a larger string, and returns the position of the match, or 0 if no match is found

if CHARINDEX('ME',@mainString) > 0
begin
    --do something
end

Edit or from daniels answer, if you're wanting to find a word (and not subcomponents of words), your CHARINDEX call would look like:

CHARINDEX(' ME ',' ' + REPLACE(REPLACE(@mainString,',',' '),'.',' ') + ' ')

(Add more recursive REPLACE() calls for any other punctuation that may occur)

Try This

<script language=JavaScript>
//Disable right mouse click Script

var message="Function Disabled!";

function clickIE4(){
if (event.button==2){
alert(message);
return false;
 }
}

function clickNS4(e){
if (document.layers||document.getElementById&&!document.all){
if (e.which==2||e.which==3){
alert(message);
return false;
}
}
}

if (document.layers){
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS4;
}
else if (document.all&&!document.getElementById){
document.onmousedown=clickIE4;
}

document.oncontextmenu=new Function("alert(message);return false")

</script>

Why not store it as an array of prices instead of object?

prices = []
$(allProducts).each(function () {
    var price = parseFloat($(this).data('price'));
    prices.push(price);
});
prices.sort(function(a, b) { return a - b }); //this is the magic line which sort the array

That way you can just

prices[0]; // cheapest
prices[prices.length - 1]; // most expensive

Note that you can do shift() and pop() to get min and max price respectively, but it will take off the price from the array.

Even better alternative is to use Sergei solution below, by using Math.max and min respectively.

EDIT:

I realized that this would be wrong if you have something like [11.5, 3.1, 3.5, 3.7] as 11.5 is treated as a string, and would come before the 3.x in dictionary order, you need to pass in custom sort function to make sure they are indeed treated as float:

prices.sort(function(a, b) { return a - b });

boolean can only be true or false because it's a primitive datatype (+ a boolean variables default value is false). You can use the class Boolean instead if you want to use null values. Boolean is a reference type, that's the reason you can assign null to a Boolean "variable". Example:

Boolean testvar = null;
if (testvar == null) { ...}

In those examples, no. If the statement is not the very last in the loop then they have very different effects.

You have to add the selector parameter, otherwise the event is directly bound instead of delegated, which only works if the element already exists (so it doesn't work for dynamically loaded content).

See http://api.jquery.com/on/#direct-and-delegated-events

Change your code to

$(document.body).on('click', '.update' ,function(){

The jQuery set receives the event then delegates it to elements matching the selector given as argument. This means that contrary to when using live, the jQuery set elements must exist when you execute the code.

As this answers receives a lot of attention, here are two supplementary advises :

1) When it's possible, try to bind the event listener to the most precise element, to avoid useless event handling.

That is, if you're adding an element of class b to an existing element of id a, then don't use

$(document.body).on('click', '#a .b', function(){

but use

$('#a').on('click', '.b', function(){

2) Be careful, when you add an element with an id, to ensure you're not adding it twice. Not only is it "illegal" in HTML to have two elements with the same id but it breaks a lot of things. For example a selector "#c" would retrieve only one element with this id.

If you want to do this through XCode's Interface Builder, you can use the menu options under Editor->Arrangement. There you'll find "Send to Front", "Send to Back", etc.

Three double quotes: " " " x " " " = "x" Excel will auto change to one double quote. e.g.:

=CONCATENATE("""x"""," hi")  

= "x" hi

Also, consider to use a repository manager such as Nexus and configure all your repositories there.

how about:

def fix_unicode(data):
    if isinstance(data, unicode):
        return data.encode('utf-8')
    elif isinstance(data, dict):
        data = dict((fix_unicode(k), fix_unicode(data[k])) for k in data)
    elif isinstance(data, list):
        for i in xrange(0, len(data)):
            data[i] = fix_unicode(data[i])
    return data

Add namespace

using System.Configuration;

and in place of

ConfigurationSettings.AppSettings

you should use

ConfigurationManager.AppSettings

String path = ConfigurationManager.AppSettings["configFile"];

On the Button:

CommandArgument='<%# Eval("myKey")%>'

On the Server Event

e.CommandArgument

I have written an article about DCEVM: Spring-mvc + Velocity + DCEVM

I think it's worth it, since my environment is running without any problems.

A simpler way can be :

new Thread(YourSampleClass).start();    

Starting from Java 9 or 8u151, you can use comment a line in the file:

<JAVA_HOME>/jre/lib/security/java.security

And change:

#crypto.policy=unlimited

to

crypto.policy=unlimited

I fix this problem following this steps:

1. Clean Solution
2. Close Visual Studio
3. Deleting /bin from the project directory
4. Restart Visual Studio
5. Rebuild Solution

It is an "INEQUALITY" operator. Get a list of comparison operators in VBA

If you don't use conda, just use :

pip install openpyxl

If you use conda, I'd recommend :

conda install -c anaconda openpyxl

instead of simply conda install openpyxl

Because there are issues right now with conda updating (see GitHub Issue #8842) ; this is being fixed and it should work again after the next release (conda 4.7.6)

Java doesn't have goto, because it makes the code unstructured and unclear to read. However, you can use break and continue as civilized form of goto without its problems.

Jumping forward using break -

ahead: {
    System.out.println("Before break");
    break ahead;
    System.out.println("After Break"); // This won't execute
}
// After a line break ahead, the code flow starts from here, after the ahead block
System.out.println("After ahead");

Output:

Before Break
After ahead

Jumping backward using continue

before: {
    System.out.println("Continue");
    continue before;
}

This will result in an infinite loop as every time the line continue before is executed, the code flow will start again from before.

Example how to use it:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.GINGERBREAD) {
     // only for gingerbread and newer versions
}

You shouldn't use the double-bracket {{ }} syntax within if or ifequal statements, you can simply access the variable there like you would in normal python:

{% if title == source %}
   ...
{% endif %}

How about

for (int k = 0; k < 10; k = k + 2) {
    if (k == 2) {
        break;
    }

    System.out.println(k);
}

The other way is a labelled loop

myloop:  for (int i=0; i < 5; i++) {

              for (int j=0; j < 5; j++) {

                if (i * j > 6) {
                  System.out.println("Breaking");
                  break myloop;
                }

                System.out.println(i + " " + j);
              }
          }

For an even better explanation you can check here

If your input is in a form and you want to get value after submit you can do like

<form onsubmit="submitLoginForm(event)">
    <input type="text" name="name">
    <input type="password" name="password">
    <input type="submit" value="Login">
</form>

<script type="text/javascript">

    function submitLoginForm(event){
        event.preventDefault();

        console.log(event.target['name'].value);
        console.log(event.target['password'].value);
    }
</script>

Benefit of this way: Example your page have 2 form for input sender and receiver information.

If you don't use form for get value then
- You can set 2 different id(or tag or name ...) for each field like sender-name and receiver-name, sender-address and receiver-address, ...
- If you set same value for 2 input, then after getElementsByName (or getElementsByTagName ...) you need to remember 0 or 1 is sender or receiver. Later if you change the order of 2 form in html, you need to check this code again

If you use form, then you can use name, address, ...

Try this code.

If you can add any item and set value in dropdown then try it.

 dropdown1.Items.Insert(0, new ListItem("---All---", "0"));

You can Removed Item in dropdown then try it.

 ListItem removeItem = dropdown1.Items.FindByText("--Please Select--");
 dropdown1.Items.Remove(removeItem);

Not sure why it's doing that. Try -s with the -o option to set the output file instead of >.

You could replace something in there by getting the index along with the item.

>>> foo = ['a', 'b', 'c', 'A', 'B', 'C']
>>> for index, item in enumerate(foo):
...     print(index, item)
...
(0, 'a')
(1, 'b')
(2, 'c')
(3, 'A')
(4, 'B')
(5, 'C')
>>> for index, item in enumerate(foo):
...     if item in ('a', 'A'):
...         foo[index] = 'replaced!'
...
>>> foo
['replaced!', 'b', 'c', 'replaced!', 'B', 'C']

Note that if you want to remove something from the list you have to iterate over a copy of the list, else you will get errors since you're trying to change the size of something you are iterating over. This can be done quite easily with slices.

Wrong:

>>> foo = ['a', 'b', 'c', 1, 2, 3]
>>> for item in foo:
...     if isinstance(item, int):
...         foo.remove(item)
...
>>> foo 
['a', 'b', 'c', 2]

The 2 is still in there because we modified the size of the list as we iterated over it. The correct way would be:

>>> foo = ['a', 'b', 'c', 1, 2, 3]
>>> for item in foo[:]:
...     if isinstance(item, int):
...         foo.remove(item)
...
>>> foo 
['a', 'b', 'c']

The short answer is the iPhone supports H.264 video, High profile and AAC audio, in container formats .mov, .mp4, or MPEG Segment .ts. MPEG Segment files are used for HTTP Live Streaming.

• For maximum compatibility with Android and desktop browsers, use H.264 + AAC in an .mp4 container.
• For extended length videos longer than 10 minutes you must use HTTP Live Streaming, which is H.264 + AAC in a series of small .ts container files (see App Store Review Guidelines rule 2.5.7).

Video

On the iPhone, H.264 is the only game in town. [1]

There are several different feature tiers or "profiles" available in H.264. All modern iPhones (3GS and above) support the High profile. These profiles are basically three different levels of algorithm "tricks" used to compress the video. More tricks give better compression, but require more CPU or dedicated hardware to decode. This is a table that lists the differences between the different profiles.

[1] Interestingly, Apple's own Facetime uses the newer H.265 (HEVC) video codec. However right now (August 2017) there is no Apple-provided library that gives access to a HEVC codec to developers. This is expected to change at some point.

In talking about what video format the iPhone supports, a distinction should be made between what the hardware can support, and what the (much lower) limits are for playback when streaming over a network.

The only data given about hardware video support by Apple about the current generation of iPhones (SE, 6S, 6S Plus, 7, 7 Plus) is that they support

4K [3840x2160] video recording at 30 fps

1080p [1920x1080] HD video recording at 30 fps or 60 fps.

Obviously the phone can play back what it can record, so we can guess that 3840x2160 at 30 fps and 1920x1080 at 60 fps represent design limits of the phone. In addition, the screen size on the 6S Plus and 7 Plus is 1920x1080. So if you're interested in playback on the phone, it doesn't make sense to send over more pixels then the screen can draw.

However, streaming video is a different matter. Since networks are slow and video is huge, it's typical to use lower resolutions, bitrates, and frame rates than the device's theoretical maximum.

The most detailed document giving recommendations for streaming is TN2224 Best Practices for Creating and Deploying HTTP Live Streaming Media for Apple Devices. Figure 3 in that document gives a table of recommended streaming parameters:

This table is from May 2016.

As you can see, Apple recommends the relatively low resolution of 768x432 as the highest recommended resolution for streaming over a cellular network. Of course this is just a recommendation and YMMV.

Audio

The question is about video, but that video generally has one or more audio tracks with it. The iPhone supports a few audio formats, but the most modern and by far most widely used is AAC. The iPhone 7 / 7 Plus, 6S Plus / 6S, SE all support AAC bitrates of 8 to 320 Kbps.

Container

The audio and video tracks go inside a container. The purpose of the container is to combine (interleave) the different tracks together, to store metadata, and to support seeking. The iPhone supports

1. QuickTime .mov,
2. MP4, and
3. MPEG-TS.

The .mov and .mp4 file formats are closely related (.mp4 is in fact based on .mov), however .mp4 is an ISO standard that has much wider support.

As noted above, you have to use MPEG-TS for videos longer than 10 minutes.

I solving doing this:

Remove the target commit

git revert --strategy resolve 222

Save commit 222 to patch file

git diff HEAD~2 HEAD~1 > 222.patch

Apply this patch to unstage

patch -p1 < 222.patch

Push to stash

git stash

Remove temp file

rm -f 222.patch

Very simple strategy in my opinion

function removeParam(parameter)
{
  var url=document.location.href;
  var urlparts= url.split('?');

 if (urlparts.length>=2)
 {
  var urlBase=urlparts.shift(); 
  var queryString=urlparts.join("?"); 

  var prefix = encodeURIComponent(parameter)+'=';
  var pars = queryString.split(/[&;]/g);
  for (var i= pars.length; i-->0;)               
      if (pars[i].lastIndexOf(prefix, 0)!==-1)   
          pars.splice(i, 1);
  url = urlBase+'?'+pars.join('&');
  window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .

}
return url;
}

This will resolve your problem

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

Prepared statement is more secure. It will convert a parameter to the specified type.

For example stmt.setString(1, user); will convert the user parameter to a String.

Suppose that the parameter contains a SQL string containing an executable command: using a prepared statement will not allow that.

It adds metacharacter (a.k.a. auto conversion) to that.

This makes it is more safe.

Schema says what tables are in database, what columns they have and how they are related. Each database has its own schema.

Replace this line:

$(this).target = "_blank";

With:

$( this ).attr( 'target', '_blank' );

That will set its HREF to _blank.

I tried several answers here, and none of them worked. Ironically, what did work was about the simplest alternative to a <br/> one could attempt:

<div style="flex-basis: 100%;"></div>

or you could also do:

<div style="width: 100%;"></div>

Place that wherever you want a new line. It seems to work even with adjacent <span>'s, but I'm using it with adjacent <div>'s.

You can use the function subset inside ggplot2. Try this

library(ggplot2)

data("iris")
iris$Sepal.Length[5:10] <- NA # create some NAs for this example

ggplot(data=subset(iris, !is.na(Sepal.Length)), aes(x=Sepal.Length)) + 
geom_bar(stat="bin")

I am sure m2eclipse Maven plugin for Eclipse - the other way around - can do that. You can configure it to download both the source files and javadoc automatically for you.

This is achieved by going into Window > Preferences > Maven and checking the "Download Artifact Sources" and "Download Artifact JavaDoc" options.

Try using a format file since your data file only has 4 columns. Otherwise, try OPENROWSET or use a staging table.

myTestFormatFiles.Fmt may look like:

9.0
4
1       SQLINT        0       3       ","      1     StudentNo      ""
2       SQLCHAR       0       100     ","      2     FirstName      SQL_Latin1_General_CP1_CI_AS
3       SQLCHAR       0       100     ","      3     LastName       SQL_Latin1_General_CP1_CI_AS
4       SQLINT        0       4       "\r\n"   4     Year           "

_{(source: microsoft.com)}

This tutorial on skipping a column with BULK INSERT may also help.

Your statement then would look like:

USE xta9354
GO
BULK INSERT xta9354.dbo.Students
    FROM 'd:\userdata\xta9_Students.txt' 
    WITH (FORMATFILE = 'C:\myTestFormatFiles.Fmt')

It's worth mentioning that

$('a').attr('href'); // gets the actual value
$('a').prop('href'); // gets the full URL always

Another way to check is to inline the function, so that the condition will be checked on every render (every props and state change)

const isDisabled = () => 
  // condition check

This works:

<button
  type="button"
  disabled={this.isDisabled()}
>
  Let Me In
</button>

but this will not work:

<button
   type="button"
   disabled={this.isDisabled}
>
  Let Me In
</button>

You should really use the standard List class. Unless, of course, this is a homework question, or you want to know how lists are implemented by STL.

You'll find plenty of simple tutorials via google, like this one. If you want to know how linked lists work "under the hood", try searching for C list examples/tutorials rather than C++.

A function to access the values:

def shape(tensor):
    s = tensor.get_shape()
    return tuple([s[i].value for i in range(0, len(s))])

Example:

batch_size, num_feats = shape(logits)

You need to have the 'data' array outside of the loop, otherwise it will get reset in every loop and also you can directly push the json. Find the solution below:-

var my_json;
$.getJSON("https://api.thingspeak.com/channels/"+did+"/feeds.json?api_key="+apikey+"&results=300", function(json1) {
console.log(json1);
var data = [];
json1.feeds.forEach(function(feed,i){
    console.log("\n The details of " + i + "th Object are :  \nCreated_at: " + feed.created_at + "\nEntry_id:" + feed.entry_id + "\nField1:" + feed.field1 + "\nField2:" + feed.field2+"\nField3:" + feed.field3);      
    my_json = feed;
    console.log(my_json); //Object {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"}
    data.push(my_json);
     //["2017-03-14T01:00:32Z", 33358, "4", "4", "0"]
}); 
console.log(data);

run single test –by filename–

Actually, one can also run a single mocha test by filename (not just by „it()-string-grepping“) if you remove the glob pattern (e.g. ./test/**/*.spec.js) from your mocha.opts, respectively create a copy, without:

node_modules/.bin/mocha --opts test/mocha.single.opts test/self-test.spec.js

Here's my mocha.single.opts (it's only different in missing the aforementioned glob line)

--require ./test/common.js
--compilers js:babel-core/register
--reporter list
--recursive

Background: While you can override the various switches from the opts-File (starting with --) you can't override the glob. That link also has some explanations.

Hint: if node_modules/.bin/mocha confuses you, to use the local package mocha. You can also write just mocha, if you have it installed globally.

And if you want the comforts of package.json: Still: remove the **/*-ish glob from your mocha.opts, insert them here, for the all-testing, leave them away for the single testing:

"test": "mocha ./test/**/*.spec.js",
"test-watch": "mocha -R list -w ./test/**/*.spec.js",
"test-single": "mocha $1",
"test-single-watch": "mocha -R list -w $1",

usage:

> npm run test

respectively

> npm run test-single -- test/ES6.self-test.spec.js 

(mind the --!)

You may already find your answer because it was some time ago you asked. But I tried to do something similar when coding ror. I wanted to run "rails server" in a new cmd window so I don't have to open a new cmd and then find my path again.

What I found out was to use the K switch like this:

start cmd /k echo Hello, World!

start before "cmd" will open the application in a new window and "/K" will execute "echo Hello, World!" after the new cmd is up.

You can also use the /C switch for something similar.

start cmd /C pause

This will then execute "pause" but close the window when the command is done. In this case after you pressed a button. I found this useful for "rails server", then when I shutdown my dev server I don't have to close the window after.

Use the following in your batch file:

start cmd.exe /c "more-batch-commands-here"

or

start cmd.exe /k "more-batch-commands-here"

/c Carries out the command specified by string and then terminates

/k Carries out the command specified by string but remains

The /c and /k options controls what happens once your command finishes running. With /c the terminal window will close automatically, leaving your desktop clean. With /k the terminal window will remain open. It's a good option if you want to run more commands manually afterwards.

Consult the cmd.exe documentation using cmd /? for more details.

Escaping Commands with White Spaces

The proper formatting of the command string becomes more complicated when using arguments with spaces. See the examples below. Note the nested double quotes in some examples.

Examples:

Run a program and pass a filename parameter:
CMD /c write.exe c:\docs\sample.txt

Run a program and pass a filename which contains whitespace:
CMD /c write.exe "c:\sample documents\sample.txt"

Spaces in program path:
CMD /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in program path + parameters:
CMD /c ""c:\Program Files\demo.cmd"" Parameter1 Param2
CMD /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch demo1 and demo2:
CMD /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

As an addition to fuzzyman's reply:

pip won't install binary packages and isn't well tested on Windows.

As Windows doesn't come with a compiler by default pip often can't be used there. easy_install can install binary packages for Windows.

Here is a trick on Windows:

• you can use easy_install <package> to install binary packages to avoid building a binary

• you can use pip uninstall <package> even if you used easy_install.

This is just a work-around that works for me on windows. Actually I always use pip if no binaries are involved.

See the current pip doku: http://www.pip-installer.org/en/latest/other-tools.html#pip-compared-to-easy-install

I will ask on the mailing list what is planned for that.

Here is the latest update:

The new supported way to install binaries is going to be wheel! It is not yet in the standard, but almost. Current version is still an alpha: 1.0.0a1

https://pypi.python.org/pypi/wheel

http://wheel.readthedocs.org/en/latest/

I will test wheel by creating an OS X installer for PySide using wheel instead of eggs. Will get back and report about this.

cheers - Chris

A quick update:

The transition to wheel is almost over. Most packages are supporting wheel.

I promised to build wheels for PySide, and I did that last summer. Works great!

HINT: A few developers failed so far to support the wheel format, simply because they forget to replace distutils by setuptools. Often, it is easy to convert such packages by replacing this single word in setup.py.

I did something similar to the jquery above, but I needed to reset my form data and graphic attachment canvases. So here is what I came up with:

    <script>
   $(document).ready(function(){

   $("#text_only_radio_button_id").click(function(){
       $("#single_pic_div").hide();
       $("#multi_pic_div").hide();
   });

   $("#pic_radio_button_id").click(function(){
      $("#single_pic_div").show();
      $("#multi_pic_div").hide();
    });

   $("#gallery_radio_button_id").click(function(){
       $("#single_pic_div").hide();
       $("#multi_pic_div").show();
                 });
    $("#my_Submit_button_ID").click(function() {
          $("#single_pic_div").hide();
          $("#multi_pic_div").hide();
          var url = "script_the_form_gets_posted_to.php"; 

       $.ajax({
       type: "POST",
       url: url,
       data: $("#html_form_id").serialize(), 
       success: function(){  
       document.getElementById("html_form_id").reset();
           var canvas=document.getElementById("canvas");
    var canvasA=document.getElementById("canvasA");
    var canvasB=document.getElementById("canvasB");
    var canvasC=document.getElementById("canvasC");
    var canvasD=document.getElementById("canvasD");

              var ctx=canvas.getContext("2d");
              var ctxA=canvasA.getContext("2d");
              var ctxB=canvasB.getContext("2d");
              var ctxC=canvasC.getContext("2d");
              var ctxD=canvasD.getContext("2d");
               ctx.clearRect(0, 0,480,480);
               ctxA.clearRect(0, 0,480,480);
               ctxB.clearRect(0, 0,480,480);        
               ctxC.clearRect(0, 0,480,480);
               ctxD.clearRect(0, 0,480,480);
               } });
           return false;
                });    });
           </script>

That works well for me, for your application of just an html form, we can simplify this jquery code like this:

       <script>
        $(document).ready(function(){

    $("#my_Submit_button_ID").click(function() {
        var url =  "script_the_form_gets_posted_to.php";
       $.ajax({
       type: "POST",
       url: url,
       data: $("#html_form_id").serialize(), 
       success: function(){  
       document.getElementById("html_form_id").reset();
            } });
           return false;
                });    });
           </script>

This will create a subshell (which means that variable values will be lost when the while loop exits):

find . -type d | while read -r dir
do
    something
done

This won't:

while read -r dir
do
    something
done < <(find . -type d)

Either one will work if there are spaces in directory names.

if ( $('#myfav').children().length > 0 ) {
     // do something
}

This should work. The children() function returns a JQuery object that contains the children. So you just need to check the size and see if it has at least one child.

.communicate() writes input (there is no input in this case so it just closes subprocess' stdin to indicate to the subprocess that there is no more input), reads all output, and waits for the subprocess to exit.

The exception EOFError is raised in the child process by raw_input() (it expected data but got EOF (no data)).

p.stdout.read() hangs forever because it tries to read all output from the child at the same time as the child waits for input (raw_input()) that causes a deadlock.

To avoid the deadlock you need to read/write asynchronously (e.g., by using threads or select) or to know exactly when and how much to read/write, for example:

from subprocess import PIPE, Popen

p = Popen(["python", "-u", "1st.py"], stdin=PIPE, stdout=PIPE, bufsize=1)
print p.stdout.readline(), # read the first line
for i in range(10): # repeat several times to show that it works
    print >>p.stdin, i # write input
    p.stdin.flush() # not necessary in this case
    print p.stdout.readline(), # read output

print p.communicate("n\n")[0], # signal the child to exit,
                               # read the rest of the output, 
                               # wait for the child to exit

Note: it is a very fragile code if read/write are not in sync; it deadlocks.

Beware of block-buffering issue (here it is solved by using "-u" flag that turns off buffering for stdin, stdout in the child).

bufsize=1 makes the pipes line-buffered on the parent side.

The url with /1.1/ in it is correct, it is the new Twitter API Version 1.1.

But you need an application and authorize your application (and the user) using oAuth.

Read more about this on the Twitter Developers documentation site :)

Note that URI encoding is good for the query part, it's not good for the domain. The domain gets encoded using punycode. You need a library like URI.js to convert between a URI and IRI (Internationalized Resource Identifier).

This is correct if you plan on using the string later as a query string:

> encodeURIComponent("http://examplé.org/rosé?rosé=rosé")
'http%3A%2F%2Fexampl%C3%A9.org%2Fros%C3%A9%3Fros%C3%A9%3Dros%C3%A9'

If you don't want ASCII characters like /, : and ? to be escaped, use encodeURI instead:

> encodeURI("http://examplé.org/rosé?rosé=rosé")
'http://exampl%C3%A9.org/ros%C3%A9?ros%C3%A9=ros%C3%A9'

However, for other use-cases, you might need uri-js instead:

> var URI = require("uri-js");
undefined
> URI.serialize(URI.parse("http://examplé.org/rosé?rosé=rosé"))
'http://xn--exampl-gva.org/ros%C3%A9?ros%C3%A9=ros%C3%A9'

Update 2018-01-07 with Spring Boot 1.5.8.RELEASE

If you want to know how to config it, how to use it, and how to control transaction. I may have answers for you.

You can see the runnable example and some explanation in https://www.surasint.com/spring-boot-with-multiple-databases-example/

I copied some code here.

First you have to set application.properties like this

#Database
database1.datasource.url=jdbc:mysql://localhost/testdb
database1.datasource.username=root
database1.datasource.password=root
database1.datasource.driver-class-name=com.mysql.jdbc.Driver

database2.datasource.url=jdbc:mysql://localhost/testdb2
database2.datasource.username=root
database2.datasource.password=root
database2.datasource.driver-class-name=com.mysql.jdbc.Driver

Then define them as providers (@Bean) like this:

@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
    return DataSourceBuilder.create().build();
}

@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
    return DataSourceBuilder.create().build();
}

Note that I have @Bean(name="datasource1") and @Bean(name="datasource2"), then you can use it when we need datasource as @Qualifier("datasource1") and @Qualifier("datasource2") , for example

@Qualifier("datasource1")
@Autowired
private DataSource dataSource;

If you do care about transaction, you have to define DataSourceTransactionManager for both of them, like this:

@Bean(name="tm1")
@Autowired
@Primary
DataSourceTransactionManager tm1(@Qualifier ("datasource1") DataSource datasource) {
    DataSourceTransactionManager txm  = new DataSourceTransactionManager(datasource);
    return txm;
}

@Bean(name="tm2")
@Autowired
DataSourceTransactionManager tm2(@Qualifier ("datasource2") DataSource datasource) {
    DataSourceTransactionManager txm  = new DataSourceTransactionManager(datasource);
    return txm;
}

Then you can use it like

@Transactional //this will use the first datasource because it is @primary

or

@Transactional("tm2")

This should be enough. See example and detail in the link above.

For me, it was that route that I was calling in my node server wasn't returning anything. Adding

    return res.status(200).json({
        message: 'success!',
        response: 'success!'
    });//

to the route I was calling resolved the issue.

There seems to be a bug in Visual Studio 2015 community. For a 64-bit project, the include folder isn't found unless it's in the win32 bit configuration Additional Include Folders list.

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

How to Use Buttons

With dates (and times) many things become simpler if you use >= start AND < end.

For example:

SELECT
  user_id
FROM
  user_logs
WHERE
      login_date >= '2014-02-01'
  AND login_date <  '2014-03-01'

In this case you still need to calculate the start date of the month you need, but that should be straight forward in any number of ways.

The end date is also simplified; just add exactly one month. No messing about with 28th, 30th, 31st, etc.

This structure also has the advantage of being able to maintain use of indexes.

Many people may suggest a form such as the following, but they do not use indexes:

WHERE
      DATEPART('year',  login_date) = 2014
  AND DATEPART('month', login_date) = 2

This involves calculating the conditions for every single row in the table (a scan) and not using index to find the range of rows that will match (a range-seek).

DELETE FROM on_search 
WHERE search_date < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 180 DAY))

Then tell read.table not to use row.names:

systems <- read.table("http://getfile.pl?test.csv", 
                      header=TRUE, sep=",", row.names=NULL)

and now your rows will simply be numbered.

Also look at read.csv which is a wrapper for read.table which already sets the sep=',' and header=TRUE arguments so that your call simplifies to

systems <- read.csv("http://getfile.pl?test.csv", row.names=NULL)

try

Environment.GetEnvironmentVariable("temp");

You can use border bottom with dotted option.

border-bottom: 1px dotted #807f80;

I found a particular edge case where I was using the tini init in an alpine container, but since I was not using the statically linked version, and Alpine uses musl libc rather than GNU LibC library installed by default, it was crashing with the very same error message.

Had I understood this and also taken time to read the documentation properly, I would have found Tini Static, which upon changing to, resolved my problem.

For those who are looking for the shortest possible "item renderer" solution from a partial, so a combo of ng-repeat and ng-include:

<div ng-repeat="item in items" ng-include src="'views/partials/item.html'" />

Actually, if you use it like this for one repeater, it will work, but won't for 2 of them! Angular (v1.2.16) will freak out for some reason if you have 2 of these one after another, so it is safer to close the div the pre-xhtml way:

<div ng-repeat="item in items" ng-include src="'views/partials/item.html'"></div>

Following commands we can use for Linux or Mac. For Windows we can use below on git bash.

List all files, first level folders, and their contents

ls * -r

List all first-level subdirectories and files

file */*

Save file list to text

file */* *>> ../files.txt
file */* -r *>> ../files-recursive.txt

Get everything

find . -type f

Save everything to file

find . -type f > ../files-all.txt

use this

(function()
{
  var exports = module.exports = {};
  exports.yourMethod =  function (success)
  {

  }
  exports.yourMethod2 =  function (success)
  {

  }


})();

Please Try, if use "extends AppCompatActivity" and present actionbar.

 ActionBar eksinbar=getSupportActionBar();
if (eksinbar != null) {
    eksinbar.setDisplayHomeAsUpEnabled(true);
    eksinbar.setHomeAsUpIndicator(R.mipmap.imagexxx);
}

Simple Helper class is here to prevent the user entering more than 2 digits after decimal :

public class CostFormatter  implements TextWatcher {

private final EditText costEditText;

public CostFormatter(EditText costEditText) {
    this.costEditText = costEditText;
}

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}

@Override
public synchronized void afterTextChanged(final Editable text) {
    String cost = text.toString().trim();

    if(!cost.endsWith(".") && cost.contains(".")){
        String numberBeforeDecimal = cost.split("\\.")[0];
        String numberAfterDecimal = cost.split("\\.")[1];

        if(numberAfterDecimal.length() > 2){
            numberAfterDecimal = numberAfterDecimal.substring(0, 2);
        }
        cost = numberBeforeDecimal + "." + numberAfterDecimal;
    }
    costEditText.removeTextChangedListener(this);
    costEditText.setText(cost);
    costEditText.setSelection(costEditText.getText().toString().trim().length());
    costEditText.addTextChangedListener(this);
}
}

In my case, I added Lucid extension to Chrome and didn't notice the problem at that moment. After about a day of working on the problem and turning the program upside down, in a post someone had mentioned Lucid. I remembered what I had done and removed the extension from Chrome and ran the program again. The problem was gone. I am working with React. I thought this might help.

If you know how to launch your program from the command line then you can run it from the platformio-ide-terminal package's terminal. See platformio-ide-terminal provides an embedded terminal within the Atom text editor. So you can issue commands, including commands to run your Java program, from within it. To install this package you can use APM with the command:

$ apm install platformio-ide-terminal --no-confirm

Alternatively, you can install it from the command palette with:

• Pressing Ctrl+Shift+P. I am assuming this is the appropriate keyboard shortcut for your platform, as you have dealt ith questions about Ubuntu in the past.
• Type Install Packages and Themes.
• Search for the platformio-ide-terminal.
• Install it.

I would check declarative-js groupBy it seems to do exactly what you are looking for. It is also:

• very performant (performance benchmark)
• written in typescript so all typpings are included.
• It is not enforcing to use 3rd party array-like objects.

import { Reducers } from 'declarative-js';
import groupBy = Reducers.groupBy;
import Map = Reducers.Map;

const data = [
    { Phase: "Phase 1", Step: "Step 1", Task: "Task 1", Value: "5" },
    { Phase: "Phase 1", Step: "Step 1", Task: "Task 2", Value: "10" },
    { Phase: "Phase 1", Step: "Step 2", Task: "Task 1", Value: "15" },
    { Phase: "Phase 1", Step: "Step 2", Task: "Task 2", Value: "20" },
    { Phase: "Phase 2", Step: "Step 1", Task: "Task 1", Value: "25" },
    { Phase: "Phase 2", Step: "Step 1", Task: "Task 2", Value: "30" },
    { Phase: "Phase 2", Step: "Step 2", Task: "Task 1", Value: "35" },
    { Phase: "Phase 2", Step: "Step 2", Task: "Task 2", Value: "40" }
];

data.reduce(groupBy(element=> element.Step), Map());
data.reduce(groupBy('Step'), Map());

Note: If you're using MAMP you MUST edit the file using the built-in editor.

Select PHP in the languages section (LH Menu Column) Next, in the main panel next to the default version drop-down click the small arrow pointing to the right. This will launch the php.ini file using the MAMP text editor. Any changes you make to this file will persist after you restart the servers.

Editing the file through Application->MAMP->bin->php->{choosen the version}->php.ini would not work. Since the application overwrites any changes you make.

Needless to say: "Here be dragons!" so please cut and paste a copy of the original and store it somewhere safe in case of disaster.

Maybe your project has not been as android project by android studio, please make sure that plugin 'android support' has been enabled(Android Studio Preferences -> Plugins -> Select Android Support)

#!/usr/bin/env sh

this is how git bash knows a file is executable. chmod a+x does nothing in gitbash. (Note: any "she-bang" will work, e.g. #!/bin/bash, etc.)

You can use this method to draw polyline on googleMap

// Draw polyline on map
public void drawPolyLineOnMap(List<LatLng> list) {
    PolylineOptions polyOptions = new PolylineOptions();
    polyOptions.color(Color.RED);
    polyOptions.width(5);
    polyOptions.addAll(list);

    googleMap.clear();
    googleMap.addPolyline(polyOptions);

    LatLngBounds.Builder builder = new LatLngBounds.Builder();
    for (LatLng latLng : list) {
        builder.include(latLng);
    }

    final LatLngBounds bounds = builder.build();

    //BOUND_PADDING is an int to specify padding of bound.. try 100.
    CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, BOUND_PADDING);
    googleMap.animateCamera(cu);
}

You need to add this line in your gradle in case you haven't.

compile 'com.google.android.gms:play-services-maps:8.4.0'

The best thing to do is to install the Tampermonkey extension.

This will allow you to easily install Greasemonkey scripts, and to easily manage them. Also it makes it easier to install userscripts directly from sites like OpenUserJS, MonkeyGuts, etc.

Finally, it unlocks most all of the GM functionality that you don't get by installing a GM script directly with Chrome. That is, more of what GM on Firefox can do, is available with Tampermonkey.

But, if you really want to install a GM script directly, it's easy a right pain on Chrome these days...

Chrome After about August, 2014:

You can still drag a file to the extensions page and it will work... Until you restart Chrome. Then it will be permanently disabled. See Continuing to "protect" Chrome users from malicious extensions for more information. Again, Tampermonkey is the smart way to go. (Or switch browsers altogether to Opera or Firefox.)

Chrome 21+ :

Chrome is changing the way extensions are installed. Userscripts are pared-down extensions on Chrome but. Starting in Chrome 21, link-click behavior is disabled for userscripts. To install a user script, drag the **.user.js* file into the Extensions page (chrome://extensions in the address input).

Older Chrome versions:

Merely drag your **.user.js* files into any Chrome window. Or click on any Greasemonkey script-link.

You'll get an installation warning:

Click Continue.

You'll get a confirmation dialog:

Click Add.

Notes:

1. Scripts installed this way have limitations compared to a Greasemonkey (Firefox) script or a Tampermonkey script. See Cross-browser user-scripting, Chrome section.

Controlling the Script and name:

By default, Chrome installs scripts in the Extensions folder¹, full of cryptic names and version numbers. And, if you try to manually add a script under this folder tree, it will be wiped the next time Chrome restarts.

To control the directories and filenames to something more meaningful, you can:

1. Create a directory that's convenient to you, and not where Chrome normally looks for extensions. For example, Create: C:\MyChromeScripts\.

2. For each script create its own subdirectory. For example, HelloWorld.

3. In that subdirectory, create or copy the script file. For example, Save this question's code as: HelloWorld.user.js.

4. You must also create a manifest file in that subdirectory, it must be named: manifest.json.

   For our example, it should contain:

   {
       "manifest_version": 2,
       "content_scripts": [ {
           "exclude_globs":    [  ],
           "include_globs":    [ "*" ],
           "js":               [ "HelloWorld.user.js" ],
           "matches":          [   "https://stackoverflow.com/*",
                                   "https://stackoverflow.com/*"
                               ],
           "run_at": "document_end"
       } ],
       "converted_from_user_script": true,
       "description":  "My first sensibly named script!",
       "name":         "Hello World",
       "version":      "1"
   }
   

   The manifest.json file is automatically generated from the meta-block by Chrome, when an user script is installed. The values of @include and @exclude meta-rules are stored in include_globs and exclude_globs, @match (recommended) is stored in the matches list. "converted_from_user_script": true is required if you want to use any of the supported GM_* methods.

5. Now, in Chrome's Extension manager (URL = chrome://extensions/), Expand "Developer mode".

6. Click the Load unpacked extension... button.

7. For the folder, paste in the folder for your script, In this example it is: C:\MyChromeScripts\HelloWorld.

8. Your script is now installed, and operational!

9. If you make any changes to the script source, hit the Reload link for them to take effect:

   

¹ The folder defaults to:

Windows XP:
  Chrome  : %AppData%\..\Local Settings\Application Data\Google\Chrome\User Data\Default\Extensions\
  Chromium: %AppData%\..\Local Settings\Application Data\Chromium\User Data\Default\Extensions\

Windows Vista/7/8:
  Chrome  : %LocalAppData%\Google\Chrome\User Data\Default\Extensions\
  Chromium: %LocalAppData%\Chromium\User Data\Default\Extensions\

Linux:
  Chrome  : ~/.config/google-chrome/Default/Extensions/
  Chromium: ~/.config/chromium/Default/Extensions/

Mac OS X:
  Chrome  : ~/Library/Application Support/Google/Chrome/Default/Extensions/
  Chromium: ~/Library/Application Support/Chromium/Default/Extensions/

Although you can change it by running Chrome with the --user-data-dir= option.

The accepted answer works for me only for the first 30 characters. This works for me:

select convert(varchar(max), convert(varbinary(max),myBlobColumn)) FROM table_name

I was looking to use this method for signatures as well, i found a sample on http://codetheory.in/.

I've added the below code to a jsfiddle

Html:

<div id="sketch">
    <canvas id="paint"></canvas>
</div>

Javascript:

 (function() {
    var canvas = document.querySelector('#paint');
    var ctx = canvas.getContext('2d');

    var sketch = document.querySelector('#sketch');
    var sketch_style = getComputedStyle(sketch);
    canvas.width = parseInt(sketch_style.getPropertyValue('width'));
    canvas.height = parseInt(sketch_style.getPropertyValue('height'));

    var mouse = {x: 0, y: 0};
    var last_mouse = {x: 0, y: 0};

    /* Mouse Capturing Work */
    canvas.addEventListener('mousemove', function(e) {
        last_mouse.x = mouse.x;
        last_mouse.y = mouse.y;

        mouse.x = e.pageX - this.offsetLeft;
        mouse.y = e.pageY - this.offsetTop;
    }, false);


    /* Drawing on Paint App */
    ctx.lineWidth = 5;
    ctx.lineJoin = 'round';
    ctx.lineCap = 'round';
    ctx.strokeStyle = 'blue';

    canvas.addEventListener('mousedown', function(e) {
        canvas.addEventListener('mousemove', onPaint, false);
    }, false);

    canvas.addEventListener('mouseup', function() {
        canvas.removeEventListener('mousemove', onPaint, false);
    }, false);

    var onPaint = function() {
        ctx.beginPath();
        ctx.moveTo(last_mouse.x, last_mouse.y);
        ctx.lineTo(mouse.x, mouse.y);
        ctx.closePath();
        ctx.stroke();
    };

}());

When using promises they can be used in a promise chain. async=false will be deprecated so using promises is your best option.

function functABC() {
  return new Promise(function(resolve, reject) {
    $.ajax({
      url: 'myPage.php',
      data: {id: id},
      success: function(data) {
        resolve(data) // Resolve promise and go to then()
      },
      error: function(err) {
        reject(err) // Reject the promise and go to catch()
      }
    });
  });
}

functABC().then(function(data) {
  // Run this when your request was successful
  console.log(data)
}).catch(function(err) {
  // Run this when promise was rejected via reject()
  console.log(err)
})

I just solved this type of problem. I was trying to increase

font-size to h4 size. I do not want to use h4 tag. I added my css after bootstrap.css it didn't work. The easiest way is this: On the HTML doc, type

<p class="h4">

You do not need to add anything to your css sheet. It works fine Question is suppose I want a size between h4 and h5? Answer why? Is this the only way to please your viewers? I will prefer this method to tampering with standard docs like bootstrap.

This will print all the subdirectories of the current directory:

print [name for name in os.listdir(".") if os.path.isdir(name)]

I'm not sure what you're doing with split("-"), but perhaps this code will help you find a solution?

If you want the full pathnames of the directories, use abspath:

print [os.path.abspath(name) for name in os.listdir(".") if os.path.isdir(name)]

Note that these pieces of code will only get the immediate subdirectories. If you want sub-sub-directories and so on, you should use walk as others have suggested.

I know this question is old, but now we can achieve the same result without WRITE_EXTERNAL_STORAGE permission. Instead of we can use File provider.

private fun storeBitmap(bitmap: Bitmap, file: File){
        requireContext().getUriForFile(file)?.run {
            requireContext().contentResolver.openOutputStream(this)?.run {
                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, this)
                close()
            }
        }
    }

How to retrieve file from provider ?

fun Context.getUriForFile(file: File): Uri? {
        return FileProvider.getUriForFile(
            this,
            "$packageName.fileprovider",
            file
        )
    }

Also do not forget register your provider in Android manifest

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"/>
    </provider>

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

Make sure you pip version matches your python version.

to get your python version use:

python -V

then install the correct pip. You might already have intall in that case try to use:

pip-2.5 install ...

pip-2.7 install ...

or for those of you using macports make sure your version match using.

port select --list pip

then change to the same python version you are using.

sudo port select --set pip pip27

Hope this helps. It work on my end.

You can use Toolbar inside the fragment and it is easy to handle. First add Toolbar to layout of the fragment

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:fitsSystemWindows="true"
    android:minHeight="?attr/actionBarSize"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:background="?attr/colorPrimaryDark">
</android.support.v7.widget.Toolbar>

Inside the onCreateView Method in the fragment you can handle the toolbar like this.

 Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
 toolbar.setTitle("Title");
 toolbar.setNavigationIcon(R.drawable.ic_arrow_back);

IT will set the toolbar,title and the back arrow navigation to toolbar.You can set any icon to setNavigationIcon method.

If you need to trigger any event when click toolbar navigation icon you can use this.

 toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
           //handle any click event
    });

If your activity have navigation drawer you may need to open that when click the navigation back button. you can open that drawer like this.

 toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
            drawer.openDrawer(Gravity.START);
        }
    });

Full code is here

 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    //inflate the layout to the fragement
    view = inflater.inflate(R.layout.layout_user,container,false);

    //initialize the toolbar
    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    toolbar.setTitle("Title");
    toolbar.setNavigationIcon(R.drawable.ic_arrow_back);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //open navigation drawer when click navigation back button
            DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
            drawer.openDrawer(Gravity.START);
        }
    });
    return view;
}

The formats and codecs supported by your build of ffmpeg can vary due the version, how it was compiled, and if any external libraries, such as libx264, were supported during compilation.

Formats (muxers and demuxers):

List all formats:

ffmpeg -formats

Display options specific to, and information about, a particular muxer:

ffmpeg -h muxer=matroska

Display options specific to, and information about, a particular demuxer:

ffmpeg -h demuxer=gif

Codecs (encoders and decoders):

List all codecs:

ffmpeg -codecs

List all encoders:

ffmpeg -encoders

List all decoders:

ffmpeg -decoders

Display options specific to, and information about, a particular encoder:

ffmpeg -h encoder=mpeg4

Display options specific to, and information about, a particular decoder:

ffmpeg -h decoder=aac

Reading the results

There is a key near the top of the output that describes each letter that precedes the name of the format, encoder, decoder, or codec:

$ ffmpeg -encoders
[…]
Encoders:
 V..... = Video
 A..... = Audio
 S..... = Subtitle
 .F.... = Frame-level multithreading
 ..S... = Slice-level multithreading
 ...X.. = Codec is experimental
 ....B. = Supports draw_horiz_band
 .....D = Supports direct rendering method 1
 ------
[…]
 V.S... mpeg4                MPEG-4 part 2

In this example V.S... indicates that the encoder mpeg4 is a Video encoder and supports Slice-level multithreading.

The error is indeed fixed by inserting this with a type annotation as the first callback parameter. My attempt to do that was botched by simultaneously changing the callback into an arrow-function:

foo.on('error', (this: Foo, err: any) => { // DON'T DO THIS

It should've been this:

foo.on('error', function(this: Foo, err: any) {

or this:

foo.on('error', function(this: typeof foo, err: any) {

A GitHub issue was created to improve the compiler's error message and highlight the actual grammar error with this and arrow-functions.

It looks like a floating-point calculation error. Check the numpy.seterr function to get more information about where it happens.

If you have ssh access, you might want to simply try du -hc /var/lib/mysql (or different datadir, as set in your my.cnf) as well.

call_user_func_array('func',$myArgs);

I ran into this issue and found that mysqlclient needs to know where to find openssl, and OSX hides this by default.

Locate openssl with brew info openssl, and then add the path to your openssl bin to your PATH:

export PATH="/usr/local/opt/openssl/bin:$PATH"

I recommend adding that to your .zshrc or .bashrc so you don't need to worry about it in the future. Then, with that variable exported (which may meed closing and re-opening your bash session), add two more env variables:

# in terminal
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

Then, finally, run:

pipenv install mysqlclient

and it should install just fine.

You can try something like this as well:

Create directive :

myApp.directive('loader', function () {
    return {
        restrict: 'A',
        scope: {cond: '=loader'},
        template: '<span ng-if="isLoading()" class="soft"><span class="fa fa-refresh fa-spin"></span></span>',
        link: function (scope) {
            scope.isLoading = function() {
                var ret = scope.cond === true || (
                        scope.cond &&
                        scope.cond.$$state &&
                        angular.isDefined(scope.cond.$$state.status) &&
                        scope.cond.$$state.status === 0
                    );
                return ret;
            }
        }
    };
}); 

Then you add something like this to mainCtrl

    // Return TRUE if some request is LOADING, else return FALSE
    $scope.isLoading = function() {
        return $http.pendingRequests.length > 0;
    };

And HTML can looks like this:

<div class="buttons loader">
    <span class="icon" loader="isLoading()"></span>
</div>

You cannot treat == or || as chars, since they are not chars, but a sequence of chars.

You could make your switch...case work on strings instead.

1. Create the temp folder c:/mysqltmp
2. In my.ini file under [mysqld] add the line tmpdir=c:/mysqltmp
3. Add full privileges to user NETWORK SERVICE for "C:\ProgramData\MySQL\MySQL Server X.Y\Data\ibdata1" file
4. Start service

These are steps for the same problem with MySQL5.7 and MySQL8.0 on Windows 10

For python3 use either with xxxx = name of yourfile.

exec(open('./xxxx.py').read())

"Class has two properties of the same name exception" can happen when you have a class member x with a public access level and a getter/setter for the same member.

As a java rule of thumb, it is not recommended to use a public access level together with getters and setters.

Check this for more details: Public property VS Private property with getter?

To fix that:

1. Change your member's access level to private and keep your getter/setter
2. Remove the member's getter and setter

ClipDrawable clipDrawable = new ClipDrawable(selectedDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
Drawable[] layers = {normalDrawable, clipDrawable, clipDrawable};
LayerDrawable seekbarDrawable = new LayerDrawable(layers);

seekBar.setThumb(wrappedDrawable);

What I found out is that MS Access will reject --Not Like "BB*"-- if not enclosed in PARENTHESES, unlike --Like "BB*"-- which is ok without parentheses.

I tested these on MS Access 2010 and are all valid:

1. Like "BB"

2. (Like "BB")

3. (Not Like "BB")

you can use something like this:

$(this).addClass('someClass');

$(Selector).trigger('ClassChanged')

$(otherSelector).bind('ClassChanged', data, function(){//stuff });

but otherwise, no, there's no predefined function to fire an event when a class changes.

I always use this code, which print the year to second in a tuple

import datetime

now = datetime.datetime.now()

time_now = (now.year, now.month, now.day, now.hour, now.minute, now.second)

print(time_now)

The :countLines subroutine below accepts two parameters: a variable name; and a filename. The number of lines in the file are counted, the result is stored in the variable, and the result is passed back to the main program.

The code has the following features:

• Reads files with Windows or Unix line endings.
• Handles Unicode as well as ANSI/ASCII text files.
• Copes with extremely long lines.
• Isn’t fazed by the null character.
• Raises an error on reading an empty file.
• Counts beyond the Batch max int limit of (31^2)-1.

@echo off & setLocal enableExtensions disableDelayedExpansion

call :countLines noOfLines "%~1" || (
    >&2 echo(file "%~nx1" is empty & goto end
) %= cond exec =%
echo(file "%~nx1" has %noOfLines% line(s)

:end - exit program with appropriate errorLevel
endLocal & goto :EOF

:countLines result= "%file%"
:: counts the number of lines in a file
setLocal disableDelayedExpansion
(set "lc=0" & call)

for /f "delims=:" %%N in ('
    cmd /d /a /c type "%~2" ^^^& ^<nul set /p "=#" ^| (^
    2^>nul findStr /n "^" ^&^& echo(^) ^| ^
    findStr /blv 1: ^| 2^>nul findStr /lnxc:" "
') do (set "lc=%%N" & call;) %= for /f =%

endlocal & set "%1=%lc%"
exit /b %errorLevel% %= countLines =%

I know it looks hideous, but it covers most edge-cases and is surprisingly fast.

        int leng = numb.length()-1;

        if (numb.charAt(0) != numb.charAt(1)) {
            System.out.print(numb.substring(0,1));
        }

        for (int i = 0; i < leng; i++){

          if (numb.charAt(i)==numb.charAt(i+1)){ 
             System.out.print(numb.substring(i,i+1));

Sometimes if you are making a target via make files double check that all c files are named correctly with correct file structure.

lateinit vs lazy

1. lateinit

   i) Use it with mutable variable[var]

    lateinit var name: String       //Allowed
    lateinit val name: String       //Not Allowed
   

ii) Allowed with only non-nullable data types

    lateinit var name: String       //Allowed
    lateinit var name: String?      //Not Allowed

iii) It is a promise to compiler that the value will be initialized in future.

NOTE: If you try to access lateinit variable without initializing it then it throws UnInitializedPropertyAccessException.

2. lazy

   i) Lazy initialization was designed to prevent unnecessary initialization of objects.

ii) Your variable will not be initialized unless you use it.

iii) It is initialized only once. Next time when you use it, you get the value from cache memory.

iv) It is thread safe(It is initialized in the thread where it is used for the first time. Other threads use the same value stored in the cache).

v) The variable can only be val.

vi) The variable can only be non-nullable.

The "none" in the shape means it does not have a pre-defined number. For example, it can be the batch size you use during training, and you want to make it flexible by not assigning any value to it so that you can change your batch size. The model will infer the shape from the context of the layers.

To get nodes connected to each layer, you can do the following:

for layer in model.layers:
    print(layer.name, layer.inbound_nodes, layer.outbound_nodes)

If you have to select the id:

 DELETE FROM table WHERE id IN (SELECT id FROM somewhere_else)

If you already know them (and they are not in the thousands):

 DELETE FROM table WHERE id IN (?,?,?,?,?,?,?,?)

You can use the ternary operator notation:

<div id="homePage" ng-class="page.isSelected(1)? 'center' : 'left'">

These can all be done with DateTime.Add(TimeSpan) since it supports positive and negative timespans.

DateTime original = new DateTime(year, month, day, 8, 0, 0);
DateTime updated = original.Add(new TimeSpan(5,0,0));

DateTime original = new DateTime(year, month, day, 17, 0, 0);
DateTime updated = original.Add(new TimeSpan(-2,0,0));

DateTime original = new DateTime(year, month, day, 17, 30, 0);
DateTime updated = original.Add(new TimeSpan(0,45,0));

Or you can also use the DateTime.Subtract(TimeSpan) method analogously.

Try with the following code:

$("textarea[id^='options_'],input[id^='options_']").on('keyup onmouseout keydown keypress blur change', 
  function() {

  }
);

A)

String str = "a string";
int length = str.length( ); // length == 8

http://download.oracle.com/javase/7/docs/api/java/lang/String.html#length%28%29

edit

If you want to count the number of a specific type of characters in a String, then a simple method is to iterate through the String checking each index against your test case.

int charCount = 0;
char temp;

for( int i = 0; i < str.length( ); i++ )
{
    temp = str.charAt( i );

    if( temp.TestCase )
        charCount++;
}

where TestCase can be isLetter( ), isDigit( ), etc.

Or if you just want to count everything but spaces, then do a check in the if like temp != ' '

B)

String str = "a string";
char atPos0 = str.charAt( 0 ); // atPos0 == 'a'

http://download.oracle.com/javase/7/docs/api/java/lang/String.html#charAt%28int%29

I check length.

if (str.length == 0) {
}

You could add \singlespacing near the beginning of your table. See the setspace instructions for more options.

An updated answer for C++11:

Use the sleep_for and sleep_until functions:

#include <chrono>
#include <thread>

int main() {
    using namespace std::this_thread; // sleep_for, sleep_until
    using namespace std::chrono; // nanoseconds, system_clock, seconds

    sleep_for(nanoseconds(10));
    sleep_until(system_clock::now() + seconds(1));
}

With these functions there's no longer a need to continually add new functions for better resolution: sleep, usleep, nanosleep, etc. sleep_for and sleep_until are template functions that can accept values of any resolution via chrono types; hours, seconds, femtoseconds, etc.

In C++14 you can further simplify the code with the literal suffixes for nanoseconds and seconds:

#include <chrono>
#include <thread>

int main() {
    using namespace std::this_thread;     // sleep_for, sleep_until
    using namespace std::chrono_literals; // ns, us, ms, s, h, etc.
    using std::chrono::system_clock;

    sleep_for(10ns);
    sleep_until(system_clock::now() + 1s);
}

Note that the actual duration of a sleep depends on the implementation: You can ask to sleep for 10 nanoseconds, but an implementation might end up sleeping for a millisecond instead, if that's the shortest it can do.

The second important use of this (beside hiding with a local variable as many answers already say) is when accessing an outer instance from a nested non-static class:

public class Outer {
  protected int a;

  public class Inner {
    protected int a;

    public int foo(){
      return Outer.this.a;
    }

    public Outer getOuter(){
      return Outer.this;
    }
  }
}

Well the first can be achieved with the document.ready function in jquery

$(document).ready(function(){...});

The changing image can be achieved with any number of plugins

• http://malsup.com/jquery/cycle/
• http://www.matto1990.com/jquery/slideshow/

If you wish you can check if images are loaded with the complete property. I know that at least the malsup jquery cycle slideshow makes use of this function internally.

check for keyCode && which & keyup || keydown

$(document).keydown(function(e){
   var code = e.keyCode || e.which;
   alert(code);
});

There's another detail here, not mentioned, related to writing to a module. Granted this may not be very common, but I've needed it from time to time.

Due to the way references and name binding works in Python, if you want to update some symbol in a module, say foo.bar, from outside that module, and have other importing code "see" that change, you have to import foo a certain way. For example:

module foo:

bar = "apples"

module a:

import foo
foo.bar = "oranges"   # update bar inside foo module object

module b:

import foo           
print foo.bar        # if executed after a's "foo.bar" assignment, will print "oranges"

However, if you import symbol names instead of module names, this will not work.

For example, if I do this in module a:

from foo import bar
bar = "oranges"

No code outside of a will see bar as "oranges" because my setting of bar merely affected the name "bar" inside module a, it did not "reach into" the foo module object and update its "bar".

                    bSuccess = WritePrinter(hPrinter, pBytes, dwCount, out dwWritten);
                    EndPagePrinter(hPrinter);
                }

        // about why not.
        if (bSuccess == false)
        {

        }
        return bSuccess;
    }

    public static bool SendFileToPrinter(string szPrinterName, string szFileName)
    {
        // Open the file.
        FileStream fs = new FileStream(szFileName, FileMode.Open);
        // Create a BinaryReader on the file.
        BinaryReader br = new BinaryReader(fs);
        // Dim an array of bytes big enough to hold the file's contents.
        Byte[] bytes = new Byte[fs.Length];
        bool bSuccess = false;
        // Your unmanaged pointer.
        IntPtr pUnmanagedBytes = new IntPtr(0);
        int nLength;

        nLength = Convert.ToInt32(fs.Length);
        // Read the contents of the file into the array.
        bytes = br.ReadBytes(nLength);
        // Allocate some unmanaged memory for those bytes.
        pUnmanagedBytes = Marshal.AllocCoTaskMem(nLength);
        // Copy the managed byte array into the unmanaged array.
        Marshal.Copy(bytes, 0, pUnmanagedBytes, nLength);
        // Send the unmanaged bytes to the printer.
        bSuccess = SendBytesToPrinter(szPrinterName, pUnmanagedBytes, nLength);
        // Free the unmanaged memory that you allocated earlier.
        Marshal.FreeCoTaskMem(pUnmanagedBytes);
        return bSuccess;
    }
    public static bool SendStringToPrinter(string szPrinterName, string szString)
    {
        IntPtr pBytes;
        Int32 dwCount;
        // How many characters are in the string?
        dwCount = szString.Length;
        // Assume that the printer is expecting ANSI text, and then convert
        // the string to ANSI text.
        pBytes = Marshal.StringToCoTaskMemAnsi(szString);
        // Send the converted ANSI string to the printer.
        SendBytesToPrinter(szPrinterName, pBytes, dwCount);
        Marshal.FreeCoTaskMem(pBytes);
        return true;
    }
}

Step 2.) Create a form with text box and button (text box will hold the ZPL to send in this example). In button click event add code...

private void button1_Click(object sender, EventArgs e)
        {
            // Allow the user to select a printer.
            PrintDialog pd = new PrintDialog();
            pd.PrinterSettings = new PrinterSettings();
            if (DialogResult.OK == pd.ShowDialog(this))
            {
                // Send a printer-specific to the printer.
                RawPrinterHelper.SendStringToPrinter(pd.PrinterSettings.PrinterName, textBox1.Text);
                MessageBox.Show("Data sent to printer.");
            }
            else
            {
                MessageBox.Show("Data not sent to printer.");
            }
        }

With this solution, you can tweak to meet specific requirements. Perhaps hardcode the specific printer. Perhaps derive the ZPL text dynamically rather than from a text box. Whatever. Perhaps you don't need a graphical interface, but this shows how to send the ZPL. Your use depends on your needs.

Just a shorthand

$(document).ready(function() {
    $(".input").val("Email Address");
        $(".input").on("focus click", function(){
            $(this).val("");
        });
    });
</script>

This post describes it very nicely.

In short: utf8_unicode_ci uses the Unicode Collation Algorithm as defined in the Unicode standards, whereas utf8_general_ci is a more simple sort order which results in "less accurate" sorting results.

Here's another way to do this:

>> from pytictoc import TicToc
>> t = TicToc() # create TicToc instance
>> t.tic() # Start timer
>> # do something
>> t.toc() # Print elapsed time
Elapsed time is 2.612231 seconds.

Comparing with traditional way:

>> from time import time
>> t1 = time()
>> # do something
>> t2 = time()
>> elapsed = t2 - t1
>> print('Elapsed time is %f seconds.' % elapsed)
Elapsed time is 2.612231 seconds.

Installation:

pip install pytictoc

Refer to the PyPi page for more details.

If you save color code in the colors.xml which is under the values folder,then you should call the following:

root.setBackgroundColor(getResources().getColor(R.color.name));

name means you declare in the <color/> tag.

For percent increase and decrease, using 2 different methods:

const a = 541
const b = 394

// Percent increase 
console.log(
  `Increase (from ${b} to ${a}) => `,
  (((a/b)-1) * 100).toFixed(2) + "%",
)

// Percent decrease
console.log(
  `Decrease (from ${a} to ${b}) => `,
  (((b/a)-1) * 100).toFixed(2) + "%",
)

// Alternatives, using .toLocaleString() 
console.log(
  `Increase (from ${b} to ${a}) => `,
  ((a/b)-1).toLocaleString('fullwide', {maximumFractionDigits:2, style:'percent'}),
)

console.log(
  `Decrease (from ${a} to ${b}) => `,
  ((b/a)-1).toLocaleString('fullwide', {maximumFractionDigits:2, style:'percent'}),
)

My Stored Procedure Requires 2 Parameters and I needed my function to return a datatable here is 100% working code

Please make sure that your procedure return some rows

Public Shared Function Get_BillDetails(AccountNumber As String) As DataTable
    Try
        Connection.Connect()
        debug.print("Look up account number " & AccountNumber)
        Dim DP As New SqlDataAdapter("EXEC SP_GET_ACCOUNT_PAYABLES_GROUP  '" & AccountNumber & "' , '" & 08/28/2013 &"'", connection.Con)
        Dim DST As New DataSet
        DP.Fill(DST)
        Return DST.Tables(0)      
    Catch ex As Exception
        Return Nothing
    End Try
End Function

Give this a try:

.table-hover tbody tr:hover td, .table-hover tbody tr:hover th {
  background-color: #color;
}
