For newbies

Python automatically compiles your script to compiled code, so called byte code, before running it.

Running a script is not considered an import and no .pyc will be created.

For example, if you have a script file abc.py that imports another module xyz.py, when you run abc.py, xyz.pyc will be created since xyz is imported, but no abc.pyc file will be created since abc.py isn’t being imported.

Python's *.py file is just a text file in which you write some lines of code. When you try to execute this file using say "python filename.py"

This command invokes Python Virtual Machine. Python Virtual Machine has 2 components: "compiler" and "interpreter". Interpreter cannot directly read the text in *.py file, so this text is first converted into a byte code which is targeted to the PVM (not hardware but PVM). PVM executes this byte code. *.pyc file is also generated, as part of running it which performs your import operation on file in shell or in some other file.

If this *.pyc file is already generated then every next time you run/execute your *.py file, system directly loads your *.pyc file which won't need any compilation(This will save you some machine cycles of processor).

Once the *.pyc file is generated, there is no need of *.py file, unless you edit it.

Can this code be simplified in one if test instead two?

nil and '' are different values. If you need to test that s is neither, IMO you should just compare against both, because it makes your intent the most clear.

That and a few alternatives, with their generated bytecode:

if not foo or foo == '' then end
     GETGLOBAL       0 -1    ; foo
     TEST            0 0 0
     JMP             3       ; to 7
     GETGLOBAL       0 -1    ; foo
     EQ              0 0 -2  ; - ""
     JMP             0       ; to 7

if foo == nil or foo == '' then end
    GETGLOBAL       0 -1    ; foo
    EQ              1 0 -2  ; - nil
    JMP             3       ; to 7
    GETGLOBAL       0 -1    ; foo
    EQ              0 0 -3  ; - ""
    JMP             0       ; to 7

if (foo or '') == '' then end
   GETGLOBAL       0 -1    ; foo
   TEST            0 0 1
   JMP             1       ; to 5
   LOADK           0 -2    ; ""
   EQ              0 0 -2  ; - ""
   JMP             0       ; to 7

The second is fastest in Lua 5.1 and 5.2 (on my machine anyway), but difference is tiny. I'd go with the first for clarity's sake.

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

Adapted from this tip and @Paul S answer

Private Sub Worksheet_Change(ByVal Target As Range)
 Dim R1 As Range
 Dim R2 As Range
 Dim InRange As Boolean
    Set R1 = Range(Target.Address)
    Set R2 = Range("C2:C20")
    Set InterSectRange = Application.Intersect(R1, R2)

  InRange = Not InterSectRange Is Nothing
     Set InterSectRange = Nothing
   If InRange = True Then
     R1.Offset(0, 1).Value = Now()
   End If
     Set R1 = Nothing
     Set R2 = Nothing
 End Sub

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

Because you're encapsulating the product again. Try to convert it like so:

let body = JSON.stringify(product); 

In Java 8, there is another approach. Collection#removeIf

eg:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);
list.add(3);

list.removeIf(i -> i > 2);

Although the answer I originally marked as chosen is correct and achieves what I asked there is a better way of doing this (which others acknowledged but didn't go into). A composite unique index should be created on the table consisting of fund_id and date.

ALTER TABLE funds ADD UNIQUE KEY `fund_date` (`fund_id`, `date`);

Then when inserting a record add the condition when a conflict is encountered:

INSERT INTO funds (`fund_id`, `date`, `price`)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE `price` = `price`; --this keeps the price what it was (no change to the table) or:

INSERT INTO funds (`fund_id`, `date`, `price`)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE `price` = 22.5; --this updates the price to the new value

This will provide much better performance to a sub-query and the structure of the table is superior. It comes with the caveat that you can't have NULL values in your unique key columns as they are still treated as values by MySQL.

I recommend unlist, which keeps the names.

unlist(df[1,])
  a   b   c 
1.0 2.0 2.6 

is.vector(unlist(df[1,]))
[1] TRUE

If you don't want a named vector:

unname(unlist(df[1,]))
[1] 1.0 2.0 2.6

ArrayList<Integer> a = new ArrayList<Number>(); 

Does not work because the fact that Number is a super class of Integer does not mean that List<Number> is a super class of List<Integer>. Generics are removed during compilation and do not exist on runtime, so parent-child relationship of collections cannot be be implemented: the information about element type is simply removed.

ArrayList<? extends Object> a1 = new ArrayList<Object>();
a1.add(3);

I cannot explain why it does not work. It is really strange but it is a fact. Really syntax <? extends Object> is mostly used for return values of methods. Even in this example Object o = a1.get(0) is valid.

ArrayList<?> a = new ArrayList<?>()

This does not work because you cannot instantiate list of unknown type...

I'd probably do something like this:

<?php

class Student
{
    public function __construct() {
        // allocate your stuff
    }

    public static function withID( $id ) {
        $instance = new self();
        $instance->loadByID( $id );
        return $instance;
    }

    public static function withRow( array $row ) {
        $instance = new self();
        $instance->fill( $row );
        return $instance;
    }

    protected function loadByID( $id ) {
        // do query
        $row = my_awesome_db_access_stuff( $id );
        $this->fill( $row );
    }

    protected function fill( array $row ) {
        // fill all properties from array
    }
}

?>

Then if i want a Student where i know the ID:

$student = Student::withID( $id );

Or if i have an array of the db row:

$student = Student::withRow( $row );

Technically you're not building multiple constructors, just static helper methods, but you get to avoid a lot of spaghetti code in the constructor this way.

As in this answer Custom HTTP Header for a specific file you can use <File> to enable CORS for a single file with this code:

<Files "index.php">
  Header set Access-Control-Allow-Origin "*"
  Header set Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"
</Files>

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

This error means that length of index index is more then 1000 bytes. MySQL and storage engines may have this restriction. I have got similar error on MySQL 5.5 - 'Specified key was too long; max key length is 3072 bytes' when ran this script:

CREATE TABLE IF NOT EXISTS test_table1 (
  column1 varchar(500) NOT NULL,
  column2 varchar(500) NOT NULL,
  column3 varchar(500) NOT NULL,
  column4 varchar(500) NOT NULL,
  column5 varchar(500) NOT NULL,
  column6 varchar(500) NOT NULL,
  KEY `index` (column1, column2, column3, column4, column5, column6)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

UTF8 is multi-bytes, and key length is calculated in this way - 500 * 3 * 6 = 9000 bytes.

But note, next query works!

CREATE TABLE IF NOT EXISTS test_table1 (
  column1 varchar(500) NOT NULL,
  column2 varchar(500) NOT NULL,
  column3 varchar(500) NOT NULL,
  column4 varchar(500) NOT NULL,
  column5 varchar(500) NOT NULL,
  column6 varchar(500) NOT NULL,
  KEY `index` (column1, column2, column3, column4, column5, column6)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

...because I used CHARSET=latin1, in this case key length is 500 * 6 = 3000 bytes.

Press shift while selecting with the mouse. This will make mouse selection behave as if mouse=a was not enabled.

Note: this trick also applies to "middle button paste": if you want to paste in vim text that was selected outside, press shift while clicking the middle button. Just make sure that insert mode is activated when you do that (you may also want to :set paste to avoid unexpected effects).

The very easiest way to do this as of today is use pnpm rather than npm and simply type:

pnpm update --latest

As a Library Project

You should add the resources in a library project as per http://developer.android.com/tools/support-library/setup.html

Section > Adding libraries with resources

You then add the android-support-v7-appcompat library in your workspace and then add it as a reference to your app project.

Defining all the resources in your app project will also work (but there are a lot of definitions to add and you have missed some of them), and it is not the recommended approach.

Use empty() to check if it is available. Try with -

will generate the error if host is not present here

if(!empty($_GET["host"]))
if($_GET["host"]!="")

Nothing like these two lines appears in Mike Williams' tutorial:

    wait = true;
    setTimeout("wait = true", 2000);

Here's a Version 3 port:

The relevant bit of code is

  // ====== Geocoding ======
  function getAddress(search, next) {

        // If that was successful
        if (status == google.maps.GeocoderStatus.OK) {
          // Lets assume that the first marker is the one we want
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          // Output the data
            var msg = 'address="' + search + '" lat=' +lat+ ' lng=' +lng+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;

Here is a short cheatsheet that covers typical cases:

// sort

// sort (reversed)
list.sort(reverseOrder())

// sort by field
list.sort(comparing(Type::getField))

// sort by field (reversed)
list.sort(comparing(Type::getField).reversed())

// sort by int field
list.sort(comparingInt(Type::getIntField))

// sort by double field (reversed)
list.sort(comparingDouble(Type::getDoubleField).reversed())

// sort by nullable field (nulls last)
list.sort(comparing(Type::getNullableField, nullsLast(naturalOrder())))

// two-level sort
list.sort(comparing(Type::getField1).thenComparing(Type::getField2))

IOS 10 Update:

I had a problem with building the fatlib with iphoneos10.0 because the regular expression in the script only expects 9.x and lower and returns 0.0 for ios 10.0

to fix this just replace

SDK_VERSION=$(echo ${SDK_NAME} | grep -o '.\{3\}$')

with

SDK_VERSION=$(echo ${SDK_NAME} | grep -o '[\\.0-9]\{3,4\}$')

I actually found it easier to use compared to XLConnect (not that either package is that difficult to use). Learning curve for both was about 5 minutes.

I use Anypoint Studio (an Eclipse based IDE). In my case everything worked well, until I found out that while running the java code, something totally different is executed. Then I have deleted the .class files. After this point I got the error message from this question's title. Cleaning the project didn't solve the problem.

After restarting the IDE everything worked well again.

You are assigning to a function call:

invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount

which is illegal in Python. The question is, what do you want to do? What does invest() do? I suppose it returns a value, namely what you're trying to use as subsequent_amount, right?

If so, then something like this should work:

amount = invest(amount,top_company(5,year,year+1),year)

To create a new commit that 'undoes' the changes of a past commit, use:

$ git revert <commit-hash>

It's also possible to actually remove a commit from an arbitrary point in the past by rebasing and then resetting, but you really don't want to do that if you have already pushed your commits to another repository (or someone else has pulled from you).

If your previous commit is a merge commit you can run this command

$ git revert -m 1 <commit-hash>

See schacon.github.com/git/howto/revert-a-faulty-merge.txt for proper ways to re-merge an un-merged branch

Unfortunately, for a database independent solution, you will need to know everything about the column. If it is used in other tables as a foreign key, they will need to be modified as well.

ALTER TABLE MyTable ADD MyNewColumn OLD_COLUMN_TYPE;
UPDATE MyTable SET MyNewColumn = MyOldColumn;
-- add all necessary triggers and constraints to the new column...
-- update all foreign key usages to point to the new column...
ALTER TABLE MyTable DROP COLUMN MyOldColumn;

For the very simplest of cases (no constraints, triggers, indexes or keys), it will take the above 3 lines. For anything more complicated it can get very messy as you fill in the missing parts.

However, as mentioned above, there are simpler database specific methods if you know which database you need to modify ahead of time.

NOTE As of iOS7, you can no longer retrieve device MAC addresses. A fixed value will be returned rather than the actual MAC

Somthing I stumbled across a while ago. Originally from here I modified it a bit and cleaned things up.

IPAddress.h
IPAddress.c

And to use it

InitAddresses();
GetIPAddresses();
GetHWAddresses();

int i;
NSString *deviceIP = nil;
for (i=0; i<MAXADDRS; ++i)
{
    static unsigned long localHost = 0x7F000001;        // 127.0.0.1
    unsigned long theAddr;

    theAddr = ip_addrs[i];

    if (theAddr == 0) break;
    if (theAddr == localHost) continue;

    NSLog(@"Name: %s MAC: %s IP: %s\n", if_names[i], hw_addrs[i], ip_names[i]);

        //decided what adapter you want details for
    if (strncmp(if_names[i], "en", 2) == 0)
    {
        NSLog(@"Adapter en has a IP of %s", ip_names[i]);
    }
}

Adapter names vary depending on the simulator/device as well as wifi or cell on the device.

Comparing val to a final is wrong!

vars are mutable vals are read only; Yes val cannot be reassigned just like final variables from Java but they can return a different value over time, so saying that they are immutable is kind of wrong;

Consider the following

var a = 10
a = 11 //Works as expected

val b = 10
b = 11 //Cannot Reassign, as expected

So for so Good!

Now consider the following for vals

val d
  get() = System.currentTimeMillis()

println(d)
//Wait a millisecond
println(d) //Surprise!, the value of d will be different both times

Hence, vars can correspond to nonfinal variables from Java, but val aren't exactly final variables either;

Although there are const in kotlin which can be like final, as they are compile time constants and don't have a custom getter, but they only work on primitives

The formula, angle(vector.b,vector.a), that I sent, give results

in the four quadrants and for any coordinates xa,ya and xb,yb.

For coordinates xa=ya=0 and or xb=yb=0 is undefined.

The angle can be bigger or smaller than pi, and can be positive

or negative.

or to application's persistence.xml in <persistence-unit><properties> tag.

Anyway hibernate logging won't include (in useful form) info on actual prepared statements' parameters.

There is an alternative way of using log4jdbc for any kind of sql logging.

The above answer assumes that you run the code that uses hibernate on JBoss, not in IDE. In this case you should configure logging also on JBoss in server\default\deploy\jboss-logging.xml, not in local IDE classpath.

Note that JBoss 6 doesn't use log4j by default. So adding log4j.properties to ear won't help. Just try to add to jboss-logging.xml:

   <logger category="org.hibernate">
     <level name="DEBUG"/>
   </logger>

Then change threshold for root logger. See SLF4J logger.debug() does not get logged in JBoss 6.

If you manage to debug hibernate queries right from IDE (without deployment), then you should have log4j.properties, log4j, slf4j-api and slf4j-log4j12 jars on classpath. See http://www.mkyong.com/hibernate/how-to-configure-log4j-in-hibernate-project/.

For Western Arabic numbers (0-9):

$words = preg_replace('/[0-9]+/', '', $words);

For all numerals including Western Arabic (e.g. Indian):

$words = '????';
$words = preg_replace('/\d+/u', '', $words);
var_dump($words); // string(0) ""

• \d+ matches multiple numerals.
• The modifier /u enables unicode string treatment. This modifier is important, otherwise the numerals would not match.

As of PHP 5.6 @$filePath will not work in CURLOPT_POSTFIELDS without CURLOPT_SAFE_UPLOAD being set and it is completely removed in PHP 7. You will need to use a CurlFile object, RFC here.

$fields = [
    'name' => new \CurlFile($filePath, 'image/png', 'filename.png')
];
curl_setopt($resource, CURLOPT_POSTFIELDS, $fields);

To be complete, a short introduction for "shell noobs":

First of all, start your shell - you can find it inside the common desktop environments under the name "Terminal" or "Shell" somewhere in the desktops application menu.

You can also try using the key combo CTRL+F2, followed by one of those commands (depending on the desktop envrionment you're using) and the ENTER key:

xfce4-terminal
gnome-console
terminal
rxvt
konsole

If all of the above fail, try using xterm - it'll work in most cases.

Hint for the following commands: Execute the commands without the $ - it's just a marker identifying that you're on the shell.

After that just fire up mongod with the --version flag:

$ mongod --version

It shows you then something like

$ mongod --version
db version v2.4.6
Wed Oct 16 16:17:00.241 git version: nogitversion

To update it just execute

$ sudo apt-get update

and then

$ sudo apt-get install mongodb

df = data.frame(date=c("2012-02-01", "2012-02-01", "2012-02-02")) 
df$day <- weekdays(as.Date(df$date))
df
##         date       day
## 1 2012-02-01 Wednesday
## 2 2012-02-01 Wednesday
## 3 2012-02-02  Thursday

Edit: Just to show another way...

The wday component of a POSIXlt object is the numeric weekday (0-6 starting on Sunday).

as.POSIXlt(df$date)$wday
## [1] 3 3 4

which you could use to subset a character vector of weekday names

c("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", 
    "Friday", "Saturday")[as.POSIXlt(df$date)$wday + 1]
## [1] "Wednesday" "Wednesday" "Thursday" 

You should read the documentation on storing stuff externally on Android. There's a multitude of problems that could exist with your current code, and I think going over the documentation might help you iron them out.

Just use for x in f: ..., this gives you line after line, is much shorter and readable (partly because it automatically stops when the file ends) and also saves you the rstrip call because the trailing newline is already stipped.

The error is caused by the exit condition, which can never be true: Even if the file is exhausted, readline will return an empty string, not None. Also note that you could still run into trouble with empty lines, e.g. at the end of the file. Adding if line.strip() == "": continue makes the code ignore blank lines, which is propably a good thing anyway.

I've tried the above answers but could not get them to work. The only code that worked for me was $window.location.search = ''

This works too:

var exeBlk = {
    () -> Void in
}
exeBlk = {
    //do something
}
//instead of nil:
exeBlk = {}

I would be inclined to include the year in the output. One way:

select to_char(DATE_CREATED, 'YYYY-MM'), sum(Num_of_Pictures)
from pictures_table
group by to_char(DATE_CREATED, 'YYYY-MM')
order by 1

Another way (more standard SQL):

select extract(year from date_created) as yr, extract(month from date_created) as mon,
       sum(Num_of_Pictures)
from pictures_table
group by extract(year from date_created), extract(month from date_created)
order by yr, mon;

Remember the order by, since you presumably want these in order, and there is no guarantee about the order that rows are returned in after a group by.

When compiling memcached under Centos 5.x i got the same problem.

The solution is to upgrade gcc and g++ to version 4.4 at least.

Make sure your CC/CXX is set (exported) to right binaries before compiling.

You can use IF EXIST to check for a file:

IF EXIST "filename" (
  REM Do one thing
) ELSE (
  REM Do another thing
)

If you do not need an "else", you can do something like this:

set __myVariable=
IF EXIST "C:\folder with space\myfile.txt" set __myVariable=C:\folder with space\myfile.txt
IF EXIST "C:\some other folder with space\myfile.txt" set __myVariable=C:\some other folder with space\myfile.txt
set __myVariable=

Here's a working example of searching for a file or a folder:

REM setup

echo "some text" > filename
mkdir "foldername"

REM finds file    

IF EXIST "filename" (
  ECHO file filename exists
) ELSE (
  ECHO file filename does not exist
)

REM does not find file

IF EXIST "filename2.txt" (
  ECHO file filename2.txt exists
) ELSE (
  ECHO file filename2.txt does not exist
)

REM folders must have a trailing backslash    

REM finds folder

IF EXIST "foldername\" (
  ECHO folder foldername exists
) ELSE (
  ECHO folder foldername does not exist
)

REM does not find folder

IF EXIST "filename\" (
  ECHO folder filename exists
) ELSE (
  ECHO folder filename does not exist
)

The right command if you want to use a file with curl is this:

curl -XPOST 'http://jfblouvmlxecs01:9200/test/_doc/1' -d @lane.json

Elasticsearch is schemaless, therefore you don't necessarily need a mapping. If you send the json as it is and you use the default mapping, every field will be indexed and analyzed using the standard analyzer.

If you want to interact with Elasticsearch through the command line, you may want to have a look at the elasticshell which should be a little bit handier than curl.

2019-07-10: Should be noted that custom mapping types is deprecated and should not be used. I updated the type in the url above to make it easier to see which was the index and which was the type as having both named "test" was confusing.

Class Names. For test fixture names, I find that "Test" is quite common in the ubiquitous language of many domains. For example, in an engineering domain: StressTest, and in a cosmetics domain: SkinTest. Sorry to disagree with Kent, but using "Test" in my test fixtures (StressTestTest?) is confusing.

"Unit" is also used a lot in domains. E.g. MeasurementUnit. Is a class called MeasurementUnitTest a test of "Measurement" or "MeasurementUnit"?

Therefore I like to use the "Qa" prefix for all my test classes. E.g. QaSkinTest and QaMeasurementUnit. It is never confused with domain objects, and using a prefix rather than a suffix means that all the test fixtures live together visually (useful if you have fakes or other support classes in your test project)

Namespaces. I work in C# and I keep my test classes in the same namespace as the class they are testing. It is more convenient than having separate test namespaces. Of course, the test classes are in a different project.

Test method names. I like to name my methods WhenXXX_ExpectYYY. It makes the precondition clear, and helps with automated documentation (a la TestDox). This is similar to the advice on the Google testing blog, but with more separation of preconditions and expectations. For example:

WhenDivisorIsNonZero_ExpectDivisionResult
WhenDivisorIsZero_ExpectError
WhenInventoryIsBelowOrderQty_ExpectBackOrder
WhenInventoryIsAboveOrderQty_ExpectReducedInventory

Deleting Host-only network helped me. 1. Open Virtual Box 2. File->Preferences-> Network 3. Select the Host-only network and remove it.

Now try starting the Genymotion.

This except for adding the following to sqlnet.ora

SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8

If you get "ORA-01017: invalid username/password; logon denied" error, then you need to re-create your password.

For those who are getting to this question via google... this error can also happen if you try to rename a field that is acting as a foreign key.

(Just in case anyone lands here) If you have sudo rights one option is to synchronize the system time

sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z"

1 << ADDR_WIDTH means 1 will be shifted 8 bits to the left and will be assigned as the value for RAM_DEPTH.

In addition, 1 << ADDR_WIDTH also means 2^ADDR_WIDTH.

Given ADDR_WIDTH = 8, then 2^8 = 256 and that will be the value for RAM_DEPTH

I tried this DB insert method, but as it does not use the model, it ignored a sluggable trait I had on the model. So, given the Model for this table exists, as soon as its migrated, I figured the model would be available to use to insert data. And I came up with this:

public function up() {
        Schema::create('parent_categories', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('slug');
            $table->timestamps();
        });
        ParentCategory::create(
            [
                'id' => 1,
                'name' => 'Occasions',
            ],
        );
    }

This worked correctly, and also took into account the sluggable trait on my Model to automatically generate a slug for this entry, and uses the timestamps too. NB. Adding the ID was no neccesary, however, I wanted specific IDs for my categories in this example. Tested working on Laravel 5.8

From http://docs.oracle.com/javase/1.4.2/docs/api/java/sql/ResultSetMetaData.html

 ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
 ResultSetMetaData rsmd = rs.getMetaData();
 int numberOfColumns = rsmd.getColumnCount();

A ResultSet contains metadata which gives the number of rows.

Change Integrated security to false in the connection string.

You can check/verify this by opening up the SQL management studio with the username/password you have and see if you can connect/open the database from there. NOTE! Could be a firewall issue as well.

i use colname(train) = paste("A", colname(train)) and it turns out to the same problem as yours.

I finally figure out that randomForest is more stingy than rpart, it can't recognize the colname with space, comma or other specific punctuation.

paste function will prepend "A" and " " as seperator with each colname. so we need to avert the space and use this sentence instead:

colname(train) = paste("A", colname(train), sep = "")

this will prepend string without space.

i used following links in my wordpress website for sharing my blogs,they work fine:

whatsapp share : https://wa.me/?text=(some-text)(your-link)

facebook share: https://www.facebook.com/sharer/sharer.php?u=(your-link)

linkedin share: http://www.linkedin.com/shareArticle?mini=true&url=(your-link)

google-plus : https://plus.google.com/share?url=(your-link)

twitter share: http://www.twitter.com/share?url=(your-link)

Use Val(txtPrice.text)

I would also allow only number and the dot char by inserting some validation code in the key press event of the price text box.

You can also use following query :

DELETE FROM Student, Enrollment USING Student INNER JOIN Enrollment ON Student.studentId = Enrollment.studentId WHERE Student.studentId= 51;

there is a better way.

View.performClick();

http://developer.android.com/reference/android/view/View.html#performClick()

this should answer all your problems. every View inherits this function, including Button, Spinner, etc.

Just to clarify, View does not have a static performClick() method. You must call performClick() on an instance of View. For example, you can't just call

View.performClick();

Instead, do something like:

View myView = findViewById(R.id.myview);
myView.performClick();

result_list = [int(v) for k,v in qs[0].items()]

qs is a list, qs[0] is the dict which you want!

.forEach already has this ability:

const someArray = [9, 2, 5];
someArray.forEach((value, index) => {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
});

But if you want the abilities of for...of, then you can map the array to the index and value:

for (const { index, value } of someArray.map((value, index) => ({ index, value }))) {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
}

That's a little long, so it may help to put it in a reusable function:

function toEntries<T>(a: T[]) {
    return a.map((value, index) => [index, value] as const);
}

for (const [index, value] of toEntries(someArray)) {
    // ..etc..
}

Iterable Version

This will work when targeting ES3 or ES5 if you compile with the --downlevelIteration compiler option.

function* toEntries<T>(values: T[] | IterableIterator<T>) {
    let index = 0;
    for (const value of values) {
        yield [index, value] as const;
        index++;
    }
}

Array.prototype.entries() - ES6+

If you are able to target ES6+ environments then you can use the .entries() method as outlined in Arnavion's answer.

If the preceding error in log was this: "ERROR - HikariPool-1 - jdbcUrl is required with driverClassName" then the solution is to rewrite "url" to "jdbc-url" according to this: Database application.yml for Spring boot from applications.properties

Here's what I do:

Generate a hidden iFrame with the data you would like to post. Since you still control that iFrame, same origin does not apply. Then submit the form in that iFrame to the ssl page. The ssl page then redirects to a non-ssl page with status messages. You have access to the iFrame.

Try installing flask through the powershell using the following command.

pip install --isolated Flask

This will allow installation to avoide environment variables and user configuration.

If you have this in your CSS file:

.myApp
{
    border-bottom-color:#FF0000;
}

and a div for instance of:

<div id="myDiv">test text</div>

you can use:

$("#myDiv").addClass('myApp');// to add the style

$("#myDiv").removeClass('myApp');// to remove the style

or you can just use

$("#myDiv").css( 'border-bottom-color','#FF0000');

I prefer the first example, keeping all the CSS related items in the CSS files.

Using a concrete example:

SELECT name FROM Folders ORDER BY name
UNION
SELECT name FROM Files ORDER BY name

Files:

Folders:

name
============================
Contacts
Desktop
Downloads

My Documents

Desired Output: (results of first select first, i.e. folders first)

Contacts
Desktop
Downloads
Favorites
Links
My Documents
f.txt
RTMS.exe
tcpdump_trial_license (1).zip
thiny1.etl
thing2.elt

SQL to achieve the desired results:

SELECT name

    SELECT 1 AS rank, name FROM Folders
    UNION 
    SELECT 2 AS rank, name FROM Files) dt
ORDER BY rank, name

read with IFS are perfect for this:

$ IFS=- read var1 var2 <<< ABCDE-123456
$ echo "$var1"
ABCDE
$ echo "$var2"
123456

Edit:

Here is how you can read each individual character into array elements:

$ read -a foo <<<"$(echo "ABCDE-123456" | sed 's/./& /g')"

Dump the array:

$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]="-" [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

If there are spaces in the string:

$ IFS=$'\v' read -a foo <<<"$(echo "ABCDE 123456" | sed 's/./&\v/g')"
$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]=" " [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

Show whitespace characters in Visual Studio Code

change the setting.json, by adding the following codes!

(PS: there is no "true" option!, even it also works.)

In your current code, what Dictionary.update() does is that it updates (update means the value is overwritten from the value for same key in passed in dictionary) the keys in current dictionary with the values from the dictionary passed in as the parameter to it (adding any new key:value pairs if existing) . A single flat dictionary does not satisfy your requirement , you either need a list of dictionaries or a dictionary with nested dictionaries.

If you want a list of dictionaries (where each element in the list would be a diciotnary of a entry) then you can make case_list as a list and then append case to it (instead of update) .

Example -

case_list = []
for entry in entries_list:
    case = {'key1': entry[0], 'key2': entry[1], 'key3':entry[2] }
    case_list.append(case)

Or you can also have a dictionary of dictionaries with the key of each element in the dictionary being entry1 or entry2 , etc and the value being the corresponding dictionary for that entry.

case_list = {}
for entry in entries_list:
    case = {'key1': value, 'key2': value, 'key3':value }
    case_list[entryname] = case  #you will need to come up with the logic to get the entryname.

My webapp had a customized tomcat/webapps/mywebapp/WEB-INF/classes/logging.properties file. I copied TldLocationsCache row to this file, finally I could see jars filenames.

# To see debug messages in TldLocationsCache, uncomment the following line: org.apache.jasper.compiler.TldLocationsCache.level = FINE

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

This isn't the all and be all of assigning values to a specific array. Since I've seen the sample was 0.1 - 0.3 you could do it this way. This method is very useful if you're designing charts and graphs. You can have the x-value incremented by 0.1 until nth time.

Or you want to design some grid of some sort.

My personal favorite, and easier than the answers I have seen here (for multiple columns):

df.drop(df.columns[22:56], axis=1, inplace=True)

Try this:

#!/usr/bin/env python

import os
import paramiko 
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('hostname', username="username", password="password")
sftp = ssh.open_sftp()
localpath = '/home/e100075/python/ss.txt'
remotepath = '/home/developers/screenshots/ss.txt'
sftp.put(localpath, remotepath)
sftp.close()
ssh.close()

As of Angular 6+, this is handled slightly differently than in previous versions. As @BeetleJuice mentions in the answer above, paramMap is new interface for getting route params, but the execution is a bit different in more recent versions of Angular. Assuming this is in a component:

private _entityId: number;

constructor(private _route: ActivatedRoute) {
    // ...
}

ngOnInit() {
    // For a static snapshot of the route...
    this._entityId = this._route.snapshot.paramMap.get('id');

    // For subscribing to the observable paramMap...
    this._route.paramMap.pipe(
        switchMap((params: ParamMap) => this._entityId = params.get('id'))
    );

    // Or as an alternative, with slightly different execution...
    this._route.paramMap.subscribe((params: ParamMap) =>  {
        this._entityId = params.get('id');
    });
}

I prefer to use both because then on direct page load I can get the ID param, and also if navigating between related entities the subscription will update properly.

For this specific problem, something like this would work:

$ sed 's/^ *//g' < input.txt > output.txt

It says to replace all spaces at the start of a line with nothing. If you also want to remove tabs, change it to this:

$ sed 's/^[ \t]+//g' < input.txt > output.txt

The leading "s" before the / means "substitute". The /'s are the delimiters for the patterns. The data between the first two /'s are the pattern to match, and the data between the second and third / is the data to replace it with. In this case you're replacing it with nothing. The "g" after the final slash means to do it "globally", ie: over the entire file rather than on only the first match it finds.

Finally, instead of < input.txt > output.txt you can use the -i option which means to edit the file "in place". Meaning, you don't need to create a second file to contain your result. If you use this option you will lose your original file.

Yes, return stops execution and exits the function. return always** exits its function immediately, with no further execution if it's inside a for loop.

It is easily verified for yourself:

function returnMe() {
  for (var i = 0; i < 2; i++) {
    if (i === 1) return i;
  }
}

console.log(returnMe());

** Notes: See this other answer about the special case of try/catch/finally and this answer about how forEach loops has its own function scope will not break out of the containing function.

Function.prototype.applyAsync = function(params, cb){
      var function_context = this;
      setTimeout(function(){
          var val = function_context.apply(undefined, params); 
          if(cb) cb(val);
      }, 0);
}

// usage
var double = function(n){return 2*n;};
var display = function(){console.log(arguments); return undefined;};
double.applyAsync([3], display);

Although not fundamentally different than the other solutions, I think my solution does a few additional nice things:

• it allows for parameters to the functions
• it passes the output of the function to the callback
• it is added to Function.prototype allowing a nicer way to call it

Also, the similarity to the built-in function Function.prototype.apply seems appropriate to me.

This worked for me and allow to use an headless browser, you just need to call the method passing your proxy.

def setProxy(proxy):
        options = Options()
        options.headless = True
        #options.add_argument("--window-size=1920,1200")
        options.add_argument("--disable-dev-shm-usage")
        options.add_argument("--no-sandbox")
        prox = Proxy()
        prox.proxy_type = ProxyType.MANUAL
        prox.http_proxy = proxy
        prox.ssl_proxy = proxy
        capabilities = webdriver.DesiredCapabilities.CHROME
        prox.add_to_capabilities(capabilities)
        return webdriver.Chrome(desired_capabilities=capabilities, options=options, executable_path=DRIVER_PATH)

The below 'd help you to add the cert to the Root Store-

certutil -enterprise -f -v -AddStore "Root" <Cert File path>

This worked for me perfectly.

Use nchar

if vector of strings is called x

(nchar(x) - nchar(gsub(' ','',x))) + 1

Find out number of spaces then add one

@Html.TextBoxFor(x => x.MobileNo, new { @class = "digit" , @maxlength = "10"})

@section Scripts 
{
    @Scripts.Render("~/bundles/jqueryui")
    @Styles.Render("~/Content/cssjqryUi")

    <script type="text/javascript">
         $(".digit").keypress(function (e) {
            if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) 
            {
                $("#errormsg").html("Digits Only").show().fadeOut("slow");
                return false;
            }
         });
    </script>
}

There are a few ways. One of the simplest is to create a my-paths.pth file (as described here). This is just a file with the extension .pth that you put into your system site-packages directory. On each line of the file you put one directory name, so you can put a line in there with /path/to/the/ and it will add that directory to the path.

You could also use the PYTHONPATH environment variable, which is like the system PATH variable but contains directories that will be added to sys.path. See the documentation.

Note that no matter what you do, sys.path contains directories not files. You can't "add a file to sys.path". You always add its directory and then you can import the file.

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } }); 

Fiddle

In Linux:

sudo docker ps -aqf "name=containername"

Or in OS X, Windows:

docker ps -aqf "name=containername"

where containername is your container name.

To avoid getting false positives, as @llia Sidorenko notes, you can use regex anchors like so:

docker ps -aqf "name=^containername$"

explanation:

• -q for quiet. output only the ID
• -a for all. works even if your container is not running
• -f for filter.
• ^ container name must start with this string
• $ container name must end with this string

I've also thought of this. Finally, my solution is to use github gist. Don't forget it also has highlight functionality. Just copy it. :)

You should use:

protected void btn1_Click(object sender, EventArgs e)
{
    Response.Redirect("otherpage.aspx");
}

You do it by stacking case labels:

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7: 
    case 12:
    ...
    break;
    ...
}

You can get raw data using below method. BTW, this pattern is for Java 6. If you are using Java 7 or newer, please consider try-with-resources pattern.

public String getJSON(String url, int timeout) {
    HttpURLConnection c = null;
    try {
        URL u = new URL(url);
        c = (HttpURLConnection) u.openConnection();
        c.setRequestMethod("GET");
        c.setRequestProperty("Content-length", "0");
        c.setUseCaches(false);
        c.setAllowUserInteraction(false);
        c.setConnectTimeout(timeout);
        c.setReadTimeout(timeout);
        c.connect();
        int status = c.getResponseCode();

        switch (status) {
            case 200:
            case 201:
                BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = br.readLine()) != null) {
                    sb.append(line+"\n");
                }
                br.close();
                return sb.toString();
        }

    } catch (MalformedURLException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } finally {
       if (c != null) {
          try {
              c.disconnect();
          } catch (Exception ex) {
             Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
          }
       }
    }
    return null;
}

And then you can use returned string with Google Gson to map JSON to object of specified class, like this:

String data = getJSON("http://localhost/authmanager.php");
AuthMsg msg = new Gson().fromJson(data, AuthMsg.class);
System.out.println(msg);

There is a sample of AuthMsg class:

public class AuthMsg {
    private int code;
    private String message;

    public int getCode() {
        return code;
    }
    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }
}

JSON returned by http://localhost/authmanager.php must look like this:

{"code":1,"message":"Logged in"}

You can use string.Format:

string template = "Hi We have these flights for you: {0}. Which one do you want";
string data = "A, B, C, D";
string message = string.Format(template, data);

You should load template from your resource file and data is your runtime values.

Be careful if you're translating to multiple languages, though: in some cases, you'll need different tokens (the {0}) in different languages.

If the main problem is the loss of precision when converting from a float to a string, one possible way to go is to convert the floats to the decimalS: http://docs.python.org/library/decimal.html.

In python 2.7 and higher you can directly convert a float to a decimal object.

One approach is to create an XML file like this in drawable, called whatever.xml:

<?xml version="1.0" encoding="utf-8"?> 
  <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_focused="true"
        android:state_pressed="true"
        android:drawable="@drawable/bgalt" />

    <item
        android:state_focused="false"
        android:state_pressed="true"
        android:drawable="@drawable/bgalt" />

    <item android:drawable="@drawable/bgnorm" />
</selector>

bgalt and bgnormare PNG images in drawable.

If you create the buttons programatically in your activity, you can set the background with:

final Button b = new Button (MyClass.this);
b.setBackgroundDrawable(getResources().getDrawable(R.drawable.whatever));

If you set your buttons' style with an XML, you would do something like:

<Button
  android:id="@+id/mybutton"
  android:background="@drawable/watever" />

And finally a link to a tutorial. Hope this helps.

This works for me:

plt.xticks(rotation=90)

If it's giving you errors with gtk, try qt.

sudo apt-get install libqt4-dev
cmake -D WITH_QT=ON ..
make
sudo make install

If this doesn't work, there's an easy way out.

sudo apt-get install libopencv-*

This will download all the required dependencies(although it seems that you have all the required libraries installed, but still you could try it once). This will probably install OpenCV 2.3.1 (Ubuntu 12.04). But since you have OpenCV 2.4.3 in /usr/local/lib include this path in /etc/ld.so.conf and do ldconfig. So now whenever you use OpenCV, you'd use the latest version. This is not the best way to do it but if you're still having problems with qt or gtk, try this once. This should work.

Update - 18th Jun 2019

I got this error on my Ubuntu(18.04.1 LTS) system for openCV 3.4.2, as the method call to cv2.imshow was failing (e.g., at the line of cv2.namedWindow(name) with error: cv2.error: OpenCV(3.4.2). The function is not implemented.). I am using anaconda. Just the below 2 steps helped me resolve:

conda remove opencv
conda install -c conda-forge opencv=4.1.0

If you are using pip, you can try

pip install opencv-contrib-python

mvn -Dschemaname=public liquibase:update

C++03's categories are too restricted to capture the introduction of rvalue references correctly into expression attributes.

With the introduction of them, it was said that an unnamed rvalue reference evaluates to an rvalue, such that overload resolution would prefer rvalue reference bindings, which would make it select move constructors over copy constructors. But it was found that this causes problems all around, for example with Dynamic Types and with qualifications.

To show this, consider

int const&& f();

int main() {
  int &&i = f(); // disgusting!
}

On pre-xvalue drafts, this was allowed, because in C++03, rvalues of non-class types are never cv-qualified. But it is intended that const applies in the rvalue-reference case, because here we do refer to objects (= memory!), and dropping const from non-class rvalues is mainly for the reason that there is no object around.

The issue for dynamic types is of similar nature. In C++03, rvalues of class type have a known dynamic type - it's the static type of that expression. Because to have it another way, you need references or dereferences, which evaluate to an lvalue. That isn't true with unnamed rvalue references, yet they can show polymorphic behavior. So to solve it,

• unnamed rvalue references become xvalues. They can be qualified and potentially have their dynamic type different. They do, like intended, prefer rvalue references during overloading, and won't bind to non-const lvalue references.

• What previously was an rvalue (literals, objects created by casts to non-reference types) now becomes an prvalue. They have the same preference as xvalues during overloading.

• What previously was an lvalue stays an lvalue.

And two groupings are done to capture those that can be qualified and can have different dynamic types (glvalues) and those where overloading prefers rvalue reference binding (rvalues).

My current choice is Razor. It is very clean and easy to read and keeps the view pages very easy to maintain. There is also intellisense support which is really great. ALos, when used with web helpers it is really powerful too.

To provide a simple sample:

@Model namespace.model
<!Doctype html>
<html>
<head>
<title>Test Razor</title>
</head>
<body>
<ul class="mainList">
@foreach(var x in ViewData.model)
{
<li>@x.PropertyName</li>
}
</ul>
</body>

And there you have it. That is very clean and easy to read. Granted, that's a simple example but even on complex pages and forms it is still very easy to read and understand.

As for the cons? Well so far (I'm new to this) when using some of the helpers for forms there is a lack of support for adding a CSS class reference which is a little annoying.

You can send email without Outlook in VBScript using the CDO.Message object. You will need to know the address of your SMTP server to use this:

Set MyEmail=CreateObject("CDO.Message")

MyEmail.Subject="Subject"
MyEmail.From="[email protected]"
MyEmail.To="[email protected]"
MyEmail.TextBody="Testing one two three."

MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing")=2

'SMTP Server
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver")="smtp.server.com"

'SMTP Port
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25 

MyEmail.Configuration.Fields.Update
MyEmail.Send

set MyEmail=nothing

If your SMTP server requires a username and password then paste these lines in above the MyEmail.Configuration.Fields.Update line:

'SMTP Auth (For Windows Auth set this to 2)
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate")=1
'Username
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusername")="username" 
'Password
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendpassword")="password"

More information on using CDO to send email with VBScript can be found on the link below: http://www.paulsadowski.com/wsh/cdo.htm

if div.title is a div then put this:

bottom: 0;

I was also facing the same issue, Everything was normal all the rights were given to the user and for folder as well. After many research i found that the wwwroot (Source code folder) was shared with some other user. I stopped sharing and it worked like a charm.

When you separate code from main.go into for example more.go, you simply pass that file to go build/go run/go install as well.

So if you previously ran

go build main.go

you now simply

go build main.go more.go

As further information:

go build --help

states:

If the arguments are a list of .go files, build treats them as a list of source files specifying a single package.

Notice that go build and go install differ from go run in that the first two state to expect package names as arguments, while the latter expects go files. However, the first two will also accept go files as go install does.

If you are wondering: build will just build the packages/files, install will produce object and binary files in your GOPATH, and run will compile and run your program.

Basically, window event may not be assigned to MVVM. In general, the Close button show a Dialog box to ask the user "save : yes/no/cancel", and this may not be achieved by the MVVM.

You may keep the OnClosing event handler, where you call the Model.Close.CanExecute() and set the boolean result in the event property. So after the CanExecute() call if true, OR in the OnClosed event, call the Model.Close.Execute()

Try with

c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -iru

When multiple versions of the .NET Framework are executing side-by-side on a single computer, the ASP.NET ISAPI version mapped to an ASP.NET application determines which version of the common language runtime (CLR) is used for the application.

Above command will Installs the version of ASP.NET that is associated with Aspnet_regiis.exe and only registers ASP.NET in IIS.

Would suggest using the following snippet. Works fine even with huge tables (otherwise you'd open dump in editor and strip unneeded stuff, right? ;)

mysqldump --no-create-info --skip-triggers --extended-insert --lock-tables --quick DB TABLE > dump.sql

At least mysql 5.x required, but who runs old stuff nowadays.. :)

On mac, open the terminal and type:

cd /usr/local/mysql/bin

then type:

./mysql -u root -p

It will ask you for the mysql root password. Enter your password and use mysql database in the terminal.

Most of all has posted correct answer. I would like to add few links, so that you can refer to them and have clear and better ideas about the same:

The difference between page and window with respect to WPF: Page vs Window in WPF?

Answer updated to Python 3.7 and more

Here is how you can turn a date-and-time object

(aka datetime.datetime object, the one that is stored inside models.DateTimeField django model field)

into a date object (aka datetime.date object):

from datetime import datetime

#your date-and-time object
# let's supposed it is defined as
datetime_element = datetime(2020, 7, 10, 12, 56, 54, 324893)

# where
# datetime_element = datetime(year, month, day, hour, minute, second, milliseconds)

# WHAT YOU WANT: your date-only object
date_element = datetime_element.date()

And just to be clear, if you print those elements, here is the output :

print(datetime_element)

2020-07-10 12:56:54.324893

print(date_element)

2020-07-10

Sounds a lot like something you would use LINQ for in .NET

While there's no "real" LINQ implementation for java yet, you might want to have a look at Quaere which could do what you describe easily enough.

Be careful with rebase. If you're sharing your develop branch with anybody, rebase can make a mess of things. Rebase is good only for your own local branches.

Rule of thumb, if you've pushed the branch to origin, don't use rebase. Instead, use merge.

You can cheat a little with OPENROWSET :

SELECT ...fieldlist...
FROM OPENROWSET('SQLNCLI', 'connection string', 'name of sp')
WHERE ...

This would still run the entire SP every time, of course.

There are well-written answers above for why you wouldn't want to do that. Here's a counter-example where perhaps you would want to do that (translated into C# from Practical Object-Oriented Design in Ruby by Sandi Metz, p. 126).

Note that GetDependency() isn't touching any instance variables. It would be static if static methods could be virtual.

(To be fair, there are probably smarter ways of doing this via dependency injection containers or object initializers...)

public class MyClass
{
    private IDependency _myDependency;

    public MyClass(IDependency someValue = null)
    {
        _myDependency = someValue ?? GetDependency();
    }

    // If this were static, it could not be overridden
    // as static methods cannot be virtual in C#.
    protected virtual IDependency GetDependency() 
    {
        return new SomeDependency();
    }
}

public class MySubClass : MyClass
{
    protected override IDependency GetDependency()
    {
        return new SomeOtherDependency();
    }
}

public interface IDependency  { }
public class SomeDependency : IDependency { }
public class SomeOtherDependency : IDependency { }

Just put these params to your TextView - It works :D

android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:focusable="true"
android:focusableInTouchMode="true"

And you also need to setSelected(true):

my_TextView.setSelected(true);

Greetings, Christopher

SELECT DISTINCT C.valueC 
FROM C 
  LEFT JOIN B ON C.id = B.lookupC
  LEFT JOIN A ON B.id = A.lookupB
WHERE C.id IS NOT NULL

I don't see a good reason why you want to limit the result sets of A and B because what you want to have is a list of all C's that are referenced by A. I did a distinct on C.valueC because i guessed you wanted a unique list of C's.

EDIT: I agree with your argument. Even if your solution looks a bit nested it seems to be the best and fastest way to use your knowledge of the data and reduce the result sets.

There is no distinct join construct you could use so just stay with what you already have :)

This is not as complicated as some of the other answers make it.

Pin the left and top edges

Just use auto layout to add constraints to pin the left and top sides of the label.

After that it will automatically resize.

Notes

• Don't add constraints for the width and height. Labels have an intrinsic size based on their text content.
• Thanks to this answer for help with this.

• No need to set sizeToFit when using auto layout. My complete code for the example project is here:

  import UIKit
  class ViewController: UIViewController {
  
      @IBOutlet weak var myLabel: UILabel!
  
      @IBAction func changeTextButtonTapped(sender: UIButton) {
          myLabel.text = "my name is really long i want it to fit in this box"
      }
  }
  

• If you want your label to line wrap then set the number of lines to 0 in IB and add myLabel.preferredMaxLayoutWidth = 150 // or whatever in code. (I also pinned my button to the bottom of the label so that it would move down when the label height increased.)

• If you are looking for dynamically sizing labels inside a UITableViewCell then see this answer.

The above could also be written with less code as:

new List<SomeType>(items).ForEach(
    i => Console.WriteLine(i)
);

This creates a generic list and populates it with the IEnumerable and then calls the list objects ForEach.

I'm surprised why no one suggested to use the WinForms Textbox.

XAML:

     <WindowsFormsHost  Margin="10" Width="70">
        <wf:TextBox x:Name="textbox1"/>
     </WindowsFormsHost>

Also don't forget the Winforms Namespace:

xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"

C#:

     AutoCompleteStringCollection stringCollection = new AutoCompleteStringCollection(){"String 1", "String 2", "etc..."};
   
     textbox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
     textbox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
     textbox1.AutoCompleteCustomSource = stringCollection;

With Autocomplete, you need to do it in the Code behind, because for some reasons, others might can explain, it throws an exception.

I am running VSCommunity 2015 in Win8.1 virtual machine installed inside a Parallels 11 virtual machine installed on my Mac OSX El Capitan. To my surprise and delight it installed and ran fine. I used it for 2 weeks without signing into my Microsoft account. I tried to login 6 weeks later and got the 30 day trial screen shown above.

However for me I was able to simply click on the link above shown as "Check for an updated license" and was prompted in to log in to my Microsoft account. I did so and it granted me a license successfully and was seamless. Now under License Status it displays as "This product is licensed to: ".

I guess I got lucky as I'm guessing this is how it is supposed to work.

[sidebar]: Over the decades I've disliked most MS products but have been out of the VS IDE development tools game for awhile, and I have to say using VSComm15 has been flawless. Using it to learn C# and the IDE itself for a new contract job and it worked perfectly and has great features.

For adding background icon always before text when length of text is not known in advance.

}

The docs give a fair indicator of what's required., however requests allow us to skip a few steps:

You only need to install the security package extras (thanks @admdrew for pointing it out)

$ pip install requests[security]

or, install them directly:

$ pip install pyopenssl ndg-httpsclient pyasn1

Requests will then automatically inject pyopenssl into urllib3

If you're on ubuntu, you may run into trouble installing pyopenssl, you'll need these dependencies:

$ apt-get install libffi-dev libssl-dev

You don't need to parse the string, it's defined as a string already.

Just do:

    private static String getStringInput (String prompt) {
     String input = EZJ.getUserInput(prompt);
     return input;
    }

If I understand you correctly you want to close the application even if the user did not click on the close button. You will need to register WindowEvents maybe with addWindowListener() or enableEvents() whichever suits your needs better.

You can then invoke the event with a call to processWindowEvent(). Here is a sample code that will create a JFrame, wait 5 seconds and close the JFrame without user interaction.

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class ClosingFrame extends JFrame implements WindowListener{

public ClosingFrame(){
    super("A Frame");
    setSize(400, 400);
            //in case the user closes the window
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setVisible(true);
            //enables Window Events on this Component
            this.addWindowListener(this);

            //start a timer
    Thread t = new Timer();
            t.start();
    }

public void windowOpened(WindowEvent e){}
public void windowClosing(WindowEvent e){}

    //the event that we are interested in
public void windowClosed(WindowEvent e){
    System.exit(0);
}

public void windowIconified(WindowEvent e){}
public void windowDeiconified(WindowEvent e){}
public void windowActivated(WindowEvent e){}
public void windowDeactivated(WindowEvent e){}

    //a simple timer 
    class Timer extends Thread{
           int time = 10;
           public void run(){
     while(time-- > 0){
       System.out.println("Still Waiting:" + time);
               try{
                 sleep(500);                     
               }catch(InterruptedException e){}
             }
             System.out.println("About to close");
    //close the frame
            ClosingFrame.this.processWindowEvent(
                 new WindowEvent(
                       ClosingFrame.this, WindowEvent.WINDOW_CLOSED));
           }
    }

    //instantiate the Frame
public static void main(String args[]){
          new ClosingFrame();
    }

}

As you can see, the processWindowEvent() method causes the WindowClosed event to be fired where you have an oportunity to do some clean up code if you require before closing the application.

If the author has a GitHub account, just click the author's username from anywhere in the commit history, and the commits you can see will be filtered down to those by that author:

You can also click the 'n commits' link below their name on the repo's "contributors" page:

Alternatively, you can directly append ?author=<theusername> or ?author=<emailaddress> to the URL. For example, https://github.com/jquery/jquery/commits/master?author=dmethvin or https://github.com/jquery/jquery/commits/[email protected] both give me:

For authors without a GitHub account, only filtering by email address will work, and you will need to manually add ?author=<emailaddress> to the URL - the author's name will not be clickable from the commits list.

You can also get the list of commits by a particular author from the command line using

git log --author=[your git name]

Example:

git log --author=Prem

The postscript() device allows creation of EPS, but only if you change some of the default values. Read ?postscript for the details.

Here is an example:

postscript("foo.eps", horizontal = FALSE, onefile = FALSE, paper = "special")
plot(1:10)
dev.off()

You can use this conversion table: http://roselab.jhu.edu/~raj/MISC/hexdectxt.html

eg, if you want a transparency of 60%, you use 3C (hex equivalent).

This is usefull for IE background gradient transparency:

filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#3C545454, endColorstr=#3C545454);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#3C545454, endColorstr=#3C545454)";

where startColorstr and endColorstr: 2 first characters are a hex value for transparency, and the six remaining are the hex color.

git blame -L 10,+1 fe25b6d^ -- src/options.cpp

You can specify a revision for git blame to look back starting from (instead of the default of HEAD); fe25b6d^ is the parent of fe25b6d.

Edit: New to Git 2.23, we have the --ignore-rev option added to git blame:

git blame --ignore-rev fe25b6d

While this doesn't answer OP's question of giving the stack of commits (you'll use git log for that, as per the other answer), it is a better way of this solution, as you won't potentially misblame the other lines.

Try this:

Function.prototype.extends = function(parent) {
  this.prototype = Object.create(parent.prototype);
};

Monkey.extends(Monster);
function Monkey() {
  Monster.apply(this, arguments); // call super
}

Edit: I put a quick demo here http://jsbin.com/anekew/1/edit. Note that extends is a reserved word in JS and you may get warnings when linting your code, you can simply name it inherits, that's what I usually do.

With this helper in place and using an object props as only parameter, inheritance in JS becomes a bit simpler:

Function.prototype.inherits = function(parent) {
  this.prototype = Object.create(parent.prototype);
};

function Monster(props) {
  this.health = props.health || 100;
}

Monster.prototype = {
  growl: function() {
    return 'Grrrrr';
  }
};

Monkey.inherits(Monster);
function Monkey() {
  Monster.apply(this, arguments);
}

var monkey = new Monkey({ health: 200 });

console.log(monkey.health); //=> 200
console.log(monkey.growl()); //=> "Grrrr"

This is a solution for reactive forms. Then there is no need to use @ViewChild decorator:

  clear() {
    this.myForm.get('someControlName').reset()
  }

Have a look at Managing Hierarchical Data in MySQL. It discusses two approaches for storing and managing hierarchical (tree-like) data in a relational database.

The first approach is the adjacency list model, which is what you essentially describe: having a foreign key that refers to the table itself. While this approach is simple, it can be very inefficient for certain queries, like building the whole tree.

The second approach discussed in the article is the nested set model. This approach is far more efficient and flexible. Refer to the article for detailed explanation and example queries.

Linux does not have any system variables that give the current CPU utilization. Instead, you have to read /proc/stat several times: each column in the cpu(n) lines gives the total CPU time, and you have to take subsequent readings of it to get percentages. See this document to find out what the various columns mean.

You have to use <Integer> instead of <int>:

int a1[] = {1,2,3};
ArrayList<Integer> arl=new ArrayList<Integer>();
for(int i : a1) {
    arl.add(i);        
    System.out.println("Arraylist contains:" + arl.get(0));
}

Place the Utils.objectToJson(entity); call before session closing.

Or you can try to set fetch mode and play with code like this

Session s = ...
DetachedCriteria dc = DetachedCriteria.forClass(MyEntity.class).add(Expression.idEq(id));
dc.setFetchMode("innerTable", FetchMode.EAGER);
Criteria c = dc.getExecutableCriteria(s);
MyEntity a = (MyEntity)c.uniqueResult();

Gradle Build Tools 2.2.0+ - Everything just works

This is the correct way to do it

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

Quick fix, add this in your options:

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false)

Now you have no idea what host you're actually connecting to, because cURL will not verify the certificate in any way. Hope you enjoy man-in-the-middle attacks!

Or just add it to your current function:

/**
 * Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
 * array containing the HTTP server response header fields and content.
 */
function get_web_page( $url )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_SSL_VERIFYPEER => false     // Disabled SSL Cert checks
    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;
}

The LINEST function described in a previous answer is the way to go, but an easier way to show the 3 coefficients of the output is to additionally use the INDEX function. In one cell, type: =INDEX(LINEST(B2:B21,A2:A21^{1,2},TRUE,FALSE),1) (by the way, the B2:B21 and A2:A21 I used are just the same values the first poster who answered this used... of course you'd change these ranges appropriately to match your data). This gives the X^2 coefficient. In an adjacent cell, type the same formula again but change the final 1 to a 2... this gives the X^1 coefficient. Lastly, in the next cell over, again type the same formula but change the last number to a 3... this gives the constant. I did notice that the three coefficients are very close but not quite identical to those derived by using the graphical trendline feature under the charts tab. Also, I discovered that LINEST only seems to work if the X and Y data are in columns (not rows), with no empty cells within the range, so be aware of that if you get a #VALUE error.

This is one of those things that's actually easier done in vanilla Javascript than jQuery. jQuery doesn't have a reset method, but the HTML Form Element does, so you can reset all the fields in a form like this:

document.getElementById('configform').reset();

If you do this via jQuery (as seen in other answers here: $('#configform')[0].reset()), the [0] is fetching the same form DOM element that you would get directly via document.getElementById. The latter approach is both more efficient and simpler though (since with the jQuery approach you first get a collection and then have to fetch an element from it, whereas with the vanilla Javascript you just get the element directly).

I have the same problem, so I simply get JSON string and deserialize to my class:

HttpResponseMessage response = await client.GetAsync("Products");
//get data as Json string 
string data = await response.Content.ReadAsStringAsync();
//use JavaScriptSerializer from System.Web.Script.Serialization
JavaScriptSerializer JSserializer = new JavaScriptSerializer();
//deserialize to your class
products = JSserializer.Deserialize<List<Product>>(data);

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

${word:$(expr index "$word" "="):1}

that gets the 7. Assuming you mean the entire rest of the string, just leave off the :1.

For executing pure SQL statements (I Don't Know About the FRAMEWORK- CodeIGNITER!!!) you can use SUB QUERY! The Syntax Would be as follows

SELECT t1.id FROM example t1 INNER JOIN (select id from (example2 t1 join example3 t2 on t1.id = t2.id)) as t2 ON t1.id = t2.id;

Hope you Get My Point!

Here is a code example. I used simple calculations instead of using precalculations like 1 day is 86400 seconds. So you can follow the logic with ease.

// Calculate time between two dates:
var date1 = new Date('1110-01-01 11:10');
var date2 = new Date();

console.log('difference in ms', date1 - date2);

// Use Math.abs() so the order of the dates can be ignored and you won't
// end up with negative numbers when date1 is before date2.
console.log('difference in ms abs', Math.abs(date1 - date2));
console.log('difference in seconds', Math.abs(date1 - date2) / 1000);

var diffInSeconds = Math.abs(date1 - date2) / 1000;
var days = Math.floor(diffInSeconds / 60 / 60 / 24);
var hours = Math.floor(diffInSeconds / 60 / 60 % 24);
var minutes = Math.floor(diffInSeconds / 60 % 60);
var seconds = Math.floor(diffInSeconds % 60);
var milliseconds = Math.round((diffInSeconds - Math.floor(diffInSeconds)) * 1000);

console.log('days', days);
console.log('hours', ('0' + hours).slice(-2));
console.log('minutes', ('0' + minutes).slice(-2));
console.log('seconds', ('0' + seconds).slice(-2));
console.log('milliseconds', ('00' + milliseconds).slice(-3));

Why not use:

Dim msg as String = String.Format("Variable = {0}", variable)

If you don't want scrolling, you can start and stop the scrolling animation as soon as you start it.

    $('document').ready(function() {
    $("html, body").animate({ scrollTop: 0 }, 500);
    return true;
    });

Also, to animate put values for 'x' and 'y', passing in 0,0 will scroll the page to the top left instantly.

window.scrollTo(x, y);

If you'd like to track only failed logins, you can use the SQL Server Audit feature (available in SQL Server 2008 and above). You will need to add the SQL server instance you want to audit, and check the failed login operation to audit.

Note: tracking failed logins via SQL Server Audit has its disadvantages. For example - it doesn't provide the names of client applications used.

If you want to audit a client application name along with each failed login, you can use an Extended Events session.

To get you started, I recommend reading this article: http://www.sqlshack.com/using-extended-events-review-sql-server-failed-logins/

The mimetypes module just recognise an file type based on file extension. If you will try to recover a file type of a file without extension, the mimetypes will not works.

First of all, I'd recommend you to go through NumPy's Quickstart tutorial, which will probably help with these basic questions.

You can directly create an array from a list as:

import numpy as np
a = np.array( [2,3,4] )

Or from a from a nested list in the same way:

import numpy as np
a = np.array( [[2,3,4], [3,4,5]] )

Or use this for an English (or mix it up for custom) format:

StringFormat='{}{0:dd/MM/yyyy}'

The easiest and least confusing solution:

a = raw_input("Enter a: ")
b = raw_input("Enter b: ")
print "a + b as strings: %s" % a  + b
a = int(a)
b = int(b)
c = a + b
print "a + b as integers: %d" % c

I found this on http://freecodeszone.blogspot.com/

Code snippet for piping content from web via http(s) to filesystem. As @starbeamrainbowlabs noticed event finish does job

var tmpFile = "/tmp/somefilename.doc";

var ws = fs.createWriteStream(tmpFile);
ws.on('finish', function() {
  // pipe done here, do something with file
});

var client = url.slice(0, 5) === 'https' ? https : http;
client.get(url, function(response) {
  return response.pipe(ws);
});

Don't want to be repetitive, but just to summarize in other way (features added in new HttpClient):

• Automatic conversion from JSON to an object
• Response type definition
• Event firing
• Simplified syntax for headers
• Interceptors

I wrote an article, where I covered the difference between old "http" and new "HttpClient". The goal was to explain it in the easiest way possible.

Simply about new HttpClient in Angular

To check for the NULL data for column1 and consider your datatype of it is String, you could use below command :

select * from tbl_name where column1 is null or column1 <> '';

This is the easiest solution for this problem -

{% autoescape on %}
   {{ body }}
{% endautoescape %}

From this page.

For those looking for a workaround, you can use an attribute selector, for instance, if your class begins with a number. Change:

.000000-8{background:url(../../images/common/000000-0.8.png);} /* DOESN'T WORK!! */

to this:

[class="000000-8"]{background:url(../../images/common/000000-0.8.png);} /* WORKS :) */

Also, if there are multiple classes, you will need to specify them in selector I think.

1. https://benfrain.com/when-and-where-you-can-use-numbers-in-id-and-class-names/
2. Is there a workaround to make CSS classes with names that start with numbers valid?

You do need to iterate through...

$typeArray = array();
$query = "select * from whatever";
$result = mysql_query($query);

if ($result) {
    while ($record = mysql_fetch_array($results)) $typeArray[] = $record['type'];
}

It is not an issue it is because of caching...

To overcome this add a timestamp to your endpoint call, e.g. axios.get('/api/products').

After timestamp it should be axios.get(/api/products?${Date.now()}.

It will resolve your 304 status code.

If you want to parse the format yourself you could do it easily with a regex such as

private static Pattern pattern = Pattern.compile("(\\d{2}):(\\d{2}):(\\d{2}).(\\d{3})");

public static long dateParseRegExp(String period) {
    Matcher matcher = pattern.matcher(period);
    if (matcher.matches()) {
        return Long.parseLong(matcher.group(1)) * 3600000L 
            + Long.parseLong(matcher.group(2)) * 60000 
            + Long.parseLong(matcher.group(3)) * 1000 
            + Long.parseLong(matcher.group(4)); 
    } else {
        throw new IllegalArgumentException("Invalid format " + period);
    }
}

However, this parsing is quite lenient and would accept 99:99:99.999 and just let the values overflow. This could be a drawback or a feature.

Framework 4: no need to use StreamWriter:

System.IO.File.WriteAllLines("SavedLists.txt", Lists.verbList);

Use extension for UIImageView to Load URL Images.

let imageCache = NSCache<NSString, UIImage>()

extension UIImageView {

    func imageURLLoad(url: URL) {

        DispatchQueue.global().async { [weak self] in
            func setImage(image:UIImage?) {
                DispatchQueue.main.async {
                    self?.image = image
                }
            }
            let urlToString = url.absoluteString as NSString
            if let cachedImage = imageCache.object(forKey: urlToString) {
                setImage(image: cachedImage)
            } else if let data = try? Data(contentsOf: url), let image = UIImage(data: data) {
                DispatchQueue.main.async {
                    imageCache.setObject(image, forKey: urlToString)
                    setImage(image: image)
                }
            }else {
                setImage(image: nil)
            }
        }
    }
}

this is how you can create an array of boolean in TS and initialize it with false:

var array: boolean[] = [false, false, false]

or another approach can be:

var array2: Array<boolean> =[false, false, false] 

you can specify the type after the colon which in this case is boolean array

For anyone still coming to this post, the other option is to simply omit the parentheses:

Sub SomeOtherSub(Stattyp As String)
    'Daty and the other variables are defined here

    CatSubProduktAreakum Stattyp, Daty + UBound(SubCategories) + 2

End Sub

The Call keywords is only really in VBA for backwards compatibilty and isn't actually required.

If however, you decide to use the Call keyword, then you have to change your syntax to suit.

'// With Call
Call Foo(Bar)

'// Without Call
Foo Bar

Both will do exactly the same thing.

That being said, there may be instances to watch out for where using parentheses unnecessarily will cause things to be evaluated where you didn't intend them to be (as parentheses do this in VBA) so with that in mind the better option is probably to omit the Call keyword and the parentheses

Here is my version. Features:

• checks for exact program name (first argument of the function). search for "mysql" will not match running "mysqld"
• searches program arguments (second argument of the function)

script:

#!/bin/bash

# $1 - cmd
# $2 - args
# return: 0 - no error, running; 1 - error, not running
function isRunning() {
    for i in $(pidof $1); do
        cat /proc/$i/cmdline | tr '\000' ' ' | grep -F -e "$2" 1>&2> /dev/null
        if [ $? -eq 0 ]; then
            return 0
        fi
    done
    return 1
}

isRunning java "-Djava.util.logging.config.file=logging.properties"
if [ $? -ne 0 ]; then
    echo "not running, starting..."
fi

It will work in IE7. But here you need to fixed the size less than the number of option and not use overflow-y:scroll. In your example you have 2 option but you set size=10, which will not work.

Suppose your select has 10 option, then fixed size=9.

Here, in your code reference you used height:100px with size:2. I remove the height css, because its not necessary and change the size:5 and it works fine.

Here is your modified code from jsfiddle:

<select size="5" style="width:100px;">
 <option>1</option>
 <option>2</option>
 <option>3</option>
 <option>4</option>
 <option>5</option>
 <option>6</option>
</select>

this will generate a larger select box than size:2 create.In case of small size the select box will not display the scrollbar,you have to check with appropriate size quantity.Without scrollbar it will work if click on the upper and lower icons of scrollbar.I show both example in your fiddle with size:2 and size greater than 2(e.g: 3,5).

Here is your desired result. I think this will help you:

CSS

  .wrapper{
    border: 1px dashed red;
    height: 150px;
    overflow-x: hidden;
    overflow-y: scroll;
    width: 150px;
 }
 .wrapper .selection{
   width:150px;
   border:1px solid #ccc
 }

HTML

<div class="wrapper">
<select size="15" class="selection">
    <option>Item 1</option>
    <option>Item 2</option>
    <option>Item 3</option>
</select>
</div>

Please try this simple function

var NanValue = function (entry) {
    if(entry=="NaN") {
        return 0.00;
    } else {
        return entry;
    }
}

This works

EXEC sp_rename 
@objname = 'ENG_TEst."[ENG_Test_A/C_TYPE]"', 
@newname = 'ENG_Test_A/C_TYPE', 
@objtype = 'COLUMN'

I had the error too. Turn out that my zip file include the code parent folder. When I unzip and inspect the zip file, the lambda_function file is under parent folder ./lambda.

Use the zip command, fix the error:

zip -r ../lambda.zip ./*

Here is another alternative that I insert at top of the Python files in tests folder:

am assuming custom_class to be your class to override heading color of the panel. just add !important to it or add inline styles or a id and add styles as they will have more specificity over class added styles.

• with !important

  .custom_class{ background-color: red !important; }

• with !important

• with ID :

  #custom_id{ background-color: red; }

-with inline styles :

<div id="custom_id" class="panel panel-default">
      <div class="panel-heading custom_class" style="background-color:red">
      </div>
    </div>

Postgres started on Linux/Unix. I suspect that reversing the slash with fix it.

\i somedir/script2.sql 

If you need to fully qualify something

\i c:/somedir/script2.sql

If that doesn't fix it, my next guess would be you need to escape the backslash.

\i somedir\\script2.sql

Helpful post, I found that my error was using else if instead of elif like so:

if [ -z "$VARIABLE1" ]; then
    # do stuff
else if [ -z "$VARIABLE2" ]; then
    # do other stuff
fi

Fixed it by changing to this:

if [ -z "$VARIABLE1" ]; then
    # do stuff
elif [ -z "$VARIABLE2" ]; then
    # do other stuff
fi

I use git gc after I do a big checkout, and have a lot of new object. it can save space. E.g. if you checkout a big SVN project using git-svn, and do a git gc, you typically save a lot of space

Try

set wildmenu
set wildmode=list:full
set wildcharm=<C-z>
let mapleader=','
nnoremap <leader>c :colorscheme <C-z><S-Tab>

in your ~/.vimrc.

The first two lines make possible matches appear as lists. You can use either or both.

The fourth line makes leader , instead of the default \.

The last line allows you to simply type ,c to get a list and a prompt to change your colorscheme.

The third line effectively allows for Tabs to appear in key maps.

(Of course, all of these strategies I've learned from the internet, and mostly SO, very recently.)

Sometimes it happens because of incomplete of some operations such as "stash save". It creates an index.lock file in the .git folder and that causes this error. What you need to do is going in to the .git folder and delete index.lock file and restart what you wanted to do.

I almost always use the standard formating ShortDateString, because I want the user to be in control of the actual output of the date.

Code

   Dim d As DateTime = Now
   Debug.WriteLine(d.ToLongDateString)
   Debug.WriteLine(d.ToShortDateString)
   Debug.WriteLine(d.ToString("d"))
   Debug.WriteLine(d.ToString("yyyy-MM-dd"))

Compare getApplication() and getApplicationContext().

getApplication returns an Application object which will allow you to manage your global application state and respond to some device situations such as onLowMemory() and onConfigurationChanged().

getApplicationContext returns the global application context - the difference from other contexts is that for example, an activity context may be destroyed (or otherwise made unavailable) by Android when your activity ends. The Application context remains available all the while your Application object exists (which is not tied to a specific Activity) so you can use this for things like Notifications that require a context that will be available for longer periods and independent of transient UI objects.

I guess it depends on what your code is doing whether these may or may not be the same - though in normal use, I'd expect them to be different.

Check out Google's Gson: http://code.google.com/p/google-gson/

From their website:

Gson gson = new Gson(); // Or use new GsonBuilder().create();
MyType target2 = gson.fromJson(json, MyType.class); // deserializes json into target2

You would just need to make a MyType class (renamed, of course) with all the fields in the json string. It might get a little more complicated when you're doing the arrays, if you prefer to do all of the parsing manually (also pretty easy) check out http://www.json.org/ and download the Java source for the Json parser objects.

You can use reliable library GSON

private static final Type DATA_TYPE_JSON = 
        new TypeToken<JSONObject>() {}.getType();           
JSONObject orderJSON = new JSONObject();
orderJSON.put("noOfLayers", "2");
orderJSON.put("baseMaterial", "mat");
System.out.println("JSON == "+orderJSON.toString());
String dataAsJson = new Gson().toJson(orderJSON, DATA_TYPE_JSON);
System.out.println("Value of dataAsJson == "+dataAsJson.toString());
String data = new Gson().toJson(dataAsJson);
System.out.println("Value of jsonString == "+data.toString());

Thats quite simple. For example, here is a random code of mine:

function news_get_by_id ( $news_id )
{

    $this->db->select('*');
    $this->db->select("DATE_FORMAT( date, '%d.%m.%Y' ) as date_human",  FALSE );
    $this->db->select("DATE_FORMAT( date, '%H:%i') as time_human",      FALSE );


    $this->db->from('news');

    $this->db->where('news_id', $news_id );


    $query = $this->db->get();

    if ( $query->num_rows() > 0 )
    {
        $row = $query->row_array();
        return $row;
    }

}   

This will return the "row" you selected as an array so you can access it like:

$array = news_get_by_id ( 1 );
echo $array['date_human'];

I also would strongly advise, not to chain the query like you do. Always have them separately like in my code, which is clearly a lot easier to read.

Please also note that if you specify the table name in from(), you call the get() function without a parameter.

If you did not understand, feel free to ask :)

Bart Kiers, your regex has a couple issues. The best way to do that is this:

(.*[a-z].*)       // For lower cases
(.*[A-Z].*)       // For upper cases
(.*\d.*)          // For digits

In this way you are searching no matter if at the beginning, at the end or at the middle. In your have I have a lot of troubles with complex passwords.

I had the same issue here. As Magnus said above, for me it was happening due to an SDK update to version 22.0.5.

After performing a full update in my Android SDK (including Google Play Services) and Android plugins in Eclipse, I was able to use play services lib in my application.

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

You should be able to do this with a pretty standard DAO recordset loop. You can see some examples at the following links:
http://msdn.microsoft.com/en-us/library/bb243789%28v=office.12%29.aspx
http://www.granite.ab.ca/access/email/recordsetloop.htm

My own standard loop looks something like this:

Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM Contacts")

'Check to see if the recordset actually contains rows
If Not (rs.EOF And rs.BOF) Then
    rs.MoveFirst 'Unnecessary in this case, but still a good habit
    Do Until rs.EOF = True
        'Perform an edit
        rs.Edit
        rs!VendorYN = True
        rs("VendorYN") = True 'The other way to refer to a field
        rs.Update

        'Save contact name into a variable
        sContactName = rs!FirstName & " " & rs!LastName

        'Move to the next record. Don't ever forget to do this.
        rs.MoveNext
    Loop
Else
    MsgBox "There are no records in the recordset."
End If

MsgBox "Finished looping through records."

rs.Close 'Close the recordset
Set rs = Nothing 'Clean up

Before you begin to curse your application you need to check this:

1. Is your application the only one using that instance of SQL Server. a. If the answer to that is NO then you need to investigate how the other applications are consuming resources on your SQl Server.run b. If the answer is yes then you must investigate your application.

2. Run SQL Server Profiler and check what activity is happening in other applications (1a) using SQL Server and check your application as well (1b).

3. If indeed your application is starved off of resources then you need to make farther investigations. For more read on this http://sqlserverplanet.com/troubleshooting/sql-server-slowness
