You could also try putting your code in the Activated event of the form, if you want it to occur, just when the form is activated. You would need to put in a boolean "has executed" check though if it is only supposed to run on the first activation.

My JSON response was like this:

{"items": 
   [
      {
      "index": 1,
      "name": "Samantha",
      "rarity": "Scarborough",
      "email": "[email protected]"
    },
      {
      "index": 2,
      "name": "Amanda",
      "rarity": "Vick",
      "email": "[email protected]"
    }]
}

So, I used ng-repeat = "item in variables.items" to display it.

Following, in my opinion will solve the problem

1. Adding the init.py to your "~/Desktop/Python_Tutorials/diveintopython/py" folder
2. Go to Window --> Preferences --> PyDev --> Interpreters --> Python Interpreter to remove your Python Interpreter setting (reason being is because PyDev unable to auto refresh any updates made to any System PythonPath)
3. Add in the Interpreter with the same details as before (this will refresh your Python Interpreter setting with updates made to your PythonPath)
4. Finally since your "~/Desktop/Python_Tutorials/diveintopython/py" folder not a standard PythonPath, you will need to add it in. There are two ways to do it

a. As per what David German suggested. However this only applicable for the particular projects you are in b. Add in "~/Desktop/Python_Tutorials/diveintopython/py" into a new PythonPath under Window --> Preferences --> PyDev --> Interpreters --> Python Interpreter --> Libraries subtab --> NewFolder

Hope it helps.

Below solution may help you.

var unmanagedDownloadcountwithfilter = from count in unmanagedDownloadCount.Where(d =>d.downloaddate >= startDate && d.downloaddate <= endDate)
group count by count.unmanagedassetregistryid into grouped

I simply had to add the ScriptManager to the page. Issue resolved.

You can inject values into a Map from the properties file using the @Value annotation like this.

The property in the properties file.

propertyname={key1:'value1',key2:'value2',....}

In your code.

@Value("#{${propertyname}}")  private Map<String,String> propertyname;

Note the hashtag as part of the annotation.

Use the built-in isinstance() function.

import pandas as pd

def f(var):
    if isinstance(var, pd.DataFrame):
        print("do stuff")

If you want to make use of nested views functionality implemented within ngRoute paradigm, try angular-route-segment - it aims to extend ngRoute rather than to replace it.

You are building a DataGridView on the fly and set the DataSource for it. That's good, but then do you add the DataGridView to the Controls collection of the hosting form?

this.Controls.Add(dataGridView1);

By the way the code is a bit confused

String connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\\Tables.accdb;Persist Security Info=True";
string sql  = "SELECT Clients  FROM Tables";
using(OleDbConnection conn = new OleDbConnection(connection))
{
     conn.Open();
     DataSet ds = new DataSet();
     DataGridView dataGridView1 = new DataGridView();
     using(OleDbDataAdapter adapter = new OleDbDataAdapter(sql,conn))
     {
         adapter.Fill(ds);
         dataGridView1.DataSource = ds;
         // Of course, before addint the datagrid to the hosting form you need to 
         // set position, location and other useful properties. 
         // Why don't you create the DataGrid with the designer and use that instance instead?
         this.Controls.Add(dataGridView1);
     }
}

EDIT After the comments below it is clear that there is a bit of confusion between the file name (TABLES.ACCDB) and the name of the table CLIENTS.
The SELECT statement is defined (in its basic form) as

 SELECT field_names_list FROM _tablename_

so the correct syntax to use for retrieving all the clients data is

 string sql  = "SELECT * FROM Clients";

where the * means -> all the fields present in the table

Can JAX-RS do Asynchronous Request like JAX-WS?

1) I don't know if the JAX-RS API includes a specific mechanism for asynchronous requests, but this answer could still change based on the client implementation you use.

Can JAX-RS access a web service that is not running on the Java platform, and vice versa?

2) I can't think of any reason it wouldn't be able to.

What does it mean by "REST is particularly useful for limited-profile devices, such as PDAs and mobile phones"?

3) REST based architectures typically will use a lightweight data format, like JSON, to send data back and forth. This is in contrast to JAX-WS which uses XML. I don't see XML by itself so significantly heavier than JSON (which some people may argue), but with JAX-WS it's how much XML is used that ends up making REST with JSON the lighter option.

What does it mean by "JAX-RS do not require XML messages or WSDL service–API definitions?

4) As stated in 3, REST architectures often use JSON to send and receive data. JAX-WS uses XML. It's not that JSON is so significantly smaller than XML by itself. It's mostly that JAX-WS specification includes lots overhead in how it communicates.

On the point about WSDL and API definitions, REST will more frequently use the URI structure and HTTP commands to define the API rather than message types, as is done in the JAX-WS. This means that you don't need to publish a WSDL document so that other users of your service can know how to talk to your service. With REST you will still need to provide some documentation to other users about how the REST service is organized and what data and HTTP commands need to be sent.

One thing to mention:

You can always try and run command:

service apache2 configtest

This will tell you when you got a malformed configuration and maybe even can tell you where the problem is.

Furthermore it helps avoid unavailability in a LIVE system:

service apache2 restart

will shutdown and then fail to start, this configtest you know beforehand "oops I did something wrong, I should fix this first" but the apache itself is still running with old configuration. :)

OK, here's the solution I settled on.

First you create a seed value using the "newseed()" function. Then you pass the seed value to the "srandom()" function. Lastly, the "srandom()" function returns a pseudo random value between 0 and 1.

The crucial bit is that the seed value is stored inside an array. If it were simply an integer or float, the value would get overwritten each time the function were called, since the values of integers, floats, strings and so forth are stored directly in the stack versus just the pointers as in the case of arrays and other objects. Thus, it's possible for the value of the seed to remain persistent.

Finally, it is possible to define the "srandom()" function such that it is a method of the "Math" object, but I'll leave that up to you to figure out. ;)

Good luck!

JavaScript:

// Global variables used for the seeded random functions, below.
var seedobja = 1103515245
var seedobjc = 12345
var seedobjm = 4294967295 //0x100000000

// Creates a new seed for seeded functions such as srandom().
function newseed(seednum)
{
    return [seednum]
}

// Works like Math.random(), except you provide your own seed as the first argument.
function srandom(seedobj)
{
    seedobj[0] = (seedobj[0] * seedobja + seedobjc) % seedobjm
    return seedobj[0] / (seedobjm - 1)
}

// Store some test values in variables.
var my_seed_value = newseed(230951)
var my_random_value_1 = srandom(my_seed_value)
var my_random_value_2 = srandom(my_seed_value)
var my_random_value_3 = srandom(my_seed_value)

// Print the values to console. Replace "WScript.Echo()" with "alert()" if inside a Web browser.
WScript.Echo(my_random_value_1)
WScript.Echo(my_random_value_2)
WScript.Echo(my_random_value_3)

Lua 4 (my personal target environment):

-- Global variables used for the seeded random functions, below.
seedobja = 1103515.245
seedobjc = 12345
seedobjm = 4294967.295 --0x100000000

-- Creates a new seed for seeded functions such as srandom().
function newseed(seednum)
    return {seednum}
end

-- Works like random(), except you provide your own seed as the first argument.
function srandom(seedobj)
    seedobj[1] = mod(seedobj[1] * seedobja + seedobjc, seedobjm)
    return seedobj[1] / (seedobjm - 1)
end

-- Store some test values in variables.
my_seed_value = newseed(230951)
my_random_value_1 = srandom(my_seed_value)
my_random_value_2 = srandom(my_seed_value)
my_random_value_3 = srandom(my_seed_value)

Ensure compiled dll of your project placed in proper bin folder.

In my case, when i have changed the compiled directory of our subproject to bin folder of our main project, it worked.

A lot of people gave the basic answer but nobody pointed out that in C++ const defaults to static at namespace level (and some gave wrong information). See the C++98 standard section 3.5.3.

First some background:

Translation unit: A source file after the pre-processor (recursively) included all its include files.

Static linkage: A symbol is only available within its translation unit.

External linkage: A symbol is available from other translation units.

At namespace level

This includes the global namespace aka global variables.

static const int sci = 0; // sci is explicitly static
const int ci = 1;         // ci is implicitly static
extern const int eci = 2; // eci is explicitly extern
extern int ei = 3;        // ei is explicitly extern
int i = 4;                // i is implicitly extern
static int si = 5;        // si is explicitly static

At function level

static means the value is maintained between function calls.
The semantics of function static variables is similar to global variables in that they reside in the program's data-segment (and not the stack or the heap), see this question for more details about static variables' lifetime.

At class level

static means the value is shared between all instances of the class and const means it doesn't change.

AssemblyVersion

Where other assemblies that reference your assembly will look. If this number changes, other assemblies have to update their references to your assembly! Only update this version, if it breaks backward compatibility. The AssemblyVersion is required.

I use the format: major.minor. This would result in:

[assembly: AssemblyVersion("1.0")]

If you're following SemVer strictly then this means you only update when the major changes, so 1.0, 2.0, 3.0, etc.

AssemblyFileVersion

Used for deployment. You can increase this number for every deployment. It is used by setup programs. Use it to mark assemblies that have the same AssemblyVersion, but are generated from different builds.

In Windows, it can be viewed in the file properties.

The AssemblyFileVersion is optional. If not given, the AssemblyVersion is used.

I use the format: major.minor.patch.build, where I follow SemVer for the first three parts and use the buildnumber of the buildserver for the last part (0 for local build). This would result in:

[assembly: AssemblyFileVersion("1.3.2.254")]

Be aware that System.Version names these parts as major.minor.build.revision!

AssemblyInformationalVersion

The Product version of the assembly. This is the version you would use when talking to customers or for display on your website. This version can be a string, like '1.0 Release Candidate'.

The AssemblyInformationalVersion is optional. If not given, the AssemblyFileVersion is used.

I use the format: major.minor[.patch] [revision as string]. This would result in:

[assembly: AssemblyInformationalVersion("1.0 RC1")]

I came across a similar problem with a meta tag. In the designer.cs, the control was defined as:

protected global::System.Web.UI.HtmlControl.HtmlGenericControl metatag;

I had to move the definition to the .aspx.cs file and define as:

protected global::System.Web.UI.HtmlControl.HtmlMeta metatag;

I suggest merging develop and master with that command

git checkout master

git merge --commit --no-ff --no-edit develop

Easiest is to use strftime (docs).

If it's for use on the view side, better to wrap it in a helper, though.

If you think about the Greek roots of the term, it should become obvious.

• Poly = many: polygon = many-sided, polystyrene = many styrenes ^(a), polyglot = many languages, and so on.
• Morph = change or form: morphology = study of biological form, Morpheus = the Greek god of dreams able to take any form.

So polymorphism is the ability (in programming) to present the same interface for differing underlying forms (data types).

For example, in many languages, integers and floats are implicitly polymorphic since you can add, subtract, multiply and so on, irrespective of the fact that the types are different. They're rarely considered as objects in the usual term.

But, in that same way, a class like BigDecimal or Rational or Imaginary can also provide those operations, even though they operate on different data types.

The classic example is the Shape class and all the classes that can inherit from it (square, circle, dodecahedron, irregular polygon, splat and so on).

With polymorphism, each of these classes will have different underlying data. A point shape needs only two co-ordinates (assuming it's in a two-dimensional space of course). A circle needs a center and radius. A square or rectangle needs two co-ordinates for the top left and bottom right corners and (possibly) a rotation. An irregular polygon needs a series of lines.

By making the class responsible for its code as well as its data, you can achieve polymorphism. In this example, every class would have its own Draw() function and the client code could simply do:

shape.Draw()

to get the correct behavior for any shape.

This is in contrast to the old way of doing things in which the code was separate from the data, and you would have had functions such as drawSquare() and drawCircle().

Object orientation, polymorphism and inheritance are all closely-related concepts and they're vital to know. There have been many "silver bullets" during my long career which basically just fizzled out but the OO paradigm has turned out to be a good one. Learn it, understand it, love it - you'll be glad you did :-)

^(a) I originally wrote that as a joke but it turned out to be correct and, therefore, not that funny. The monomer styrene happens to be made from carbon and hydrogen, C8H8, and polystyrene is made from groups of that, (C8H8)n.

Perhaps I should have stated that a polyp was many occurrences of the letter p although, now that I've had to explain the joke, even that doesn't seem funny either.

Sometimes, you should just quit while you're behind :-)

I have same problem and i found solution which is given below with full datepicker using simple HTML,Javascript and CSS. In this code i prepare formate like dd/mm/yyyy but you can work any.

HTML Code:

    <body>
<input type="date" id="dt" onchange="mydate1();" hidden/>
<input type="text" id="ndt"  onclick="mydate();" hidden />
<input type="button" Value="Date" onclick="mydate();" />
</body>

CSS Code:

#dt{text-indent: -500px;height:25px; width:200px;}

Javascript Code :

function mydate()
{
  //alert("");
document.getElementById("dt").hidden=false;
document.getElementById("ndt").hidden=true;
}
function mydate1()
{
 d=new Date(document.getElementById("dt").value);
dt=d.getDate();
mn=d.getMonth();
mn++;
yy=d.getFullYear();
document.getElementById("ndt").value=dt+"/"+mn+"/"+yy
document.getElementById("ndt").hidden=false;
document.getElementById("dt").hidden=true;
}

Output:

Usage:

control.InvokeIfRequired(c => c.Visible = false);

return control.InvokeIfRequired(c => {
    c.Visible = value

    return c.Visible;
});

Code:

using System;
using System.ComponentModel;

namespace Extensions
{
    public static class SynchronizeInvokeExtensions
    {
        public static void InvokeIfRequired<T>(this T obj, Action<T> action)
            where T : ISynchronizeInvoke
        {
            if (obj.InvokeRequired)
            {
                obj.Invoke(action, new object[] { obj });
            }
            else
            {
                action(obj);
            }
        }

        public static TOut InvokeIfRequired<TIn, TOut>(this TIn obj, Func<TIn, TOut> func) 
            where TIn : ISynchronizeInvoke
        {
            return obj.InvokeRequired
                ? (TOut)obj.Invoke(func, new object[] { obj })
                : func(obj);
        }
    }
}

I am not a very experienced PowerShell user by any means, but the little bit of it that I was exposed to impressed me a great deal. You can chain the built-in cmdlets together to do just about anything that you could do at a Unix prompt, and there's some additional goodness for doing things like exporting to CSV, HTML tables, and for more in-depth system administration types of jobs.

And if you really needed something like sed, there's always UnixUtils or GnuWin32, which you could integrate with PowerShell fairly easily.

As a longtime Unix user, I did however have a bit of trouble getting used to the command naming scheme, and I certainly would have benefitted more from it if I knew more .NET.

So essentially, I say it's well worth learning it if the Windows-only-ness of it doesn't pose a problem.

If you have some form data for example sent to home#action, now you want to redirect them to house#act while keeping the parameters, you can do this

redirect_to act_house_path(request.parameters)

its work short code

$('.SeeMore2').click(function(){ var $this = $(this).toggleClass('SeeMore2'); if($(this).hasClass('SeeMore2')) { $(this).text('See More');
} else { $(this).text('See Less'); } });

You can temporarily increase the cache size and do one dummy select and then reset the cache size back to 1. So for example

ALTER SEQUENCE mysequence INCREMENT BY 100;

select mysequence.nextval from dual;

ALTER SEQUENCE mysequence INCREMENT BY 1;

git rm --cached will remove it from the commit set ("un-adding" it); that sounds like what you want.

I just found the solution, kind of answering to my own question in case anyone else stumbles upon it.

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,            "http://url/url/url" );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );

curl_setopt($ch, CURLOPT_POSTFIELDS,     "body goes here" ); 
curl_setopt($ch, CURLOPT_HTTPHEADER,     array('Content-Type: text/plain')); 

$result=curl_exec ($ch);

Do NOT loop through all cells!! There is a lot of overhead in communications between worksheets and VBA, for both reading and writing. Looping through all cells will be agonizingly slow. I'm talking hours.

Instead, load an entire sheet at once into a Variant array. In Excel 2003, this takes about 2 seconds (and 250 MB of RAM). Then you can loop through it in no time at all.

In Excel 2007 and later, sheets are about 1000 times larger (1048576 rows × 16384 columns = 17 billion cells, compared to 65536 rows × 256 columns = 17 million in Excel 2003). You will run into an "Out of memory" error if you try to load the whole sheet into a Variant; on my machine I can only load 32 million cells at once. So you have to limit yourself to the range you know has actual data in it, or load the sheet bit by bit, e.g. 30 columns at a time.

Option Explicit

Sub test()

    Dim varSheetA As Variant
    Dim varSheetB As Variant
    Dim strRangeToCheck As String
    Dim iRow As Long
    Dim iCol As Long

    strRangeToCheck = "A1:IV65536"
    ' If you know the data will only be in a smaller range, reduce the size of the ranges above.
    Debug.Print Now
    varSheetA = Worksheets("Sheet1").Range(strRangeToCheck)
    varSheetB = Worksheets("Sheet2").Range(strRangeToCheck) ' or whatever your other sheet is.
    Debug.Print Now

    For iRow = LBound(varSheetA, 1) To UBound(varSheetA, 1)
        For iCol = LBound(varSheetA, 2) To UBound(varSheetA, 2)
            If varSheetA(iRow, iCol) = varSheetB(iRow, iCol) Then
                ' Cells are identical.
                ' Do nothing.
            Else
                ' Cells are different.
                ' Code goes here for whatever it is you want to do.
            End If
        Next iCol
    Next iRow

End Sub

To compare to a sheet in a different workbook, open that workbook and get the sheet as follows:

Set wbkA = Workbooks.Open(filename:="C:\MyBook.xls")
Set varSheetA = wbkA.Worksheets("Sheet1") ' or whatever sheet you need

Try it like this

INSERT INTO table1 (field1, field3) VALUES (5,10)

Then field2 and field4 should have default values.

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

Build Timestamp Plugin will be the Best Answer to get the TIMESTAMPS in the Build process.

Follow the below Simple steps to get the "BUILD_TIMESTAMP" variable enabled.

STEP 1:

Manage Jenkins -> Plugin Manager -> Installed...
Search for "Build Timestamp Plugin".
Install with or without Restart.

STEP 2:

Manage Jenkins -> Configure System.
Search for 'Build Timestamp' section, then Enable the CHECKBOX.
Select the TIMEZONE, TIME format you want to setup with..Save the Page.

USAGE:

When Configuring the Build with ANT or MAVEN, 
Please declare a Global variable as, 
E.G.  btime=${BUILD_TIMESTAMP}
(use this in your Properties box in ANT or MAVEN Build Section)

use 'btime' in your Code to any String Variables etc..

Swift 3 extension wrapper from @Nikolai Ruhe answer.

extension UIImageView {

    func maskWith(color: UIColor) {
        guard let tempImage = image?.withRenderingMode(.alwaysTemplate) else { return }
        image = tempImage
        tintColor = color
    }

}

It can be use for UIButton as well, e.g:

button.imageView?.maskWith(color: .blue)

float(item) do the right thing: it converts its argument to float and and return it, but it doesn't change argument in-place. A simple fix for your code is:

new_list = []
for item in list:
    new_list.append(float(item))

The same code can written shorter using list comprehension: new_list = [float(i) for i in list]

To change list in-place:

for index, item in enumerate(list):
    list[index] = float(item)

BTW, avoid using list for your variables, since it masquerades built-in function with the same name.

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

Example:

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

When you assign a variable to empty curly braces {} eg: new_set = {}, it becomes a dictionary. To create an empty set, assign the variable to a 'set()' ie: new_set = set()

I added the following 2 parameters: /np /nfl

So together with the 5 parameters from AndyGeek's answer, which are /njh /njs /ndl /nc /ns you get the following and it's silent:

ROBOCOPY [source] [target] /NFL /NDL /NJH /NJS /nc /ns /np

/NFL : No File List - don't log file names.
/NDL : No Directory List - don't log directory names.
/NJH : No Job Header.
/NJS : No Job Summary.
/NP  : No Progress - don't display percentage copied.
/NS  : No Size - don't log file sizes.
/NC  : No Class - don't log file classes.

I had the same issue and tried most of the solutions mentioned above and they did not fix it.. At then end, I went to my .csproj file and viewed it in the text editor, I found that my xml file that I put in the /Drawable was not set to be AndroidResouces it was just of type Content.

Changing that to be of type AndroidResouces fixed the issue for me.

You can use http://www.fontsquirrel.com/fontface/generator to encode any font for websites. It'll generate the code to include the font.

I don't really use it for fonts over 30px. They look much better as an image (because images are anti-aliased, and some browsers don't anti-alias fonts in the browser).

See: http://www.truetype-typography.com/ttalias.htm

I originally came in here to find how to make PyTest print in VSCode's console while running/debugging the unit test from there. This can be done with the following launch.json configuration. Given .venv the virtual environment folder.

    "version": "0.2.0",
    "configurations": [
        {
            "name": "PyTest",
            "type": "python",
            "request": "launch",
            "stopOnEntry": false,
            "pythonPath": "${config:python.pythonPath}",
            "module": "pytest",
            "args": [
                "-sv"
            ],
            "cwd": "${workspaceRoot}",
            "env": {},
            "envFile": "${workspaceRoot}/.venv",
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput"
            ]
        }
    ]
}

You can accomplish this (if I understand what you are trying to do) using dynamic SQL.

The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.

So you can use something like this approach:

SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue 
    + ' AS fld1 FROM tbl' + @KeyValue

EXEC (@stmt)

First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:

'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'

At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE (or EXEC for short).

The old-school sp_executesql procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.

FOLLOWUP

EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.

Consider what would happen if @KeyValue contained the string:

'1 AS foo; DROP TABLE students; -- '

The string we would produce as a SQL statement would be:

'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'

When we EXECUTE that string as a SQL statement:

INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...

And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)

One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'. If an illegal character is found, then reject the value, and exit without executing any SQL.

I got this issue solved.

I was trying to compile this project "Waveform Android" - https://github.com/Semantive/waveform-android

and got I this error.

I am using Android studio on Ubuntu 14.04LTS.

I have JAVA 8 Installed.

in my gradle build script file there was some statements as below.

retrolambda {
    jdk System.getenv("JAVA8_HOME")
    oldJdk System.getenv("JAVA7_HOME")
    javaVersion JavaVersion.VERSION_1_7
}

I changed the "JAVA8_HOME" to "JAVA_HOME" because in my environment variables the java home directory is set as JAVA_HOME not as JAVA8_HOME and then It built succesfully.

after changing the build script.

retrolambda {
    jdk System.getenv("JAVA_HOME")
    oldJdk System.getenv("JAVA7_HOME")
    javaVersion JavaVersion.VERSION_1_7
}

Or the other way you can create a new environment variable named JAVA8_HOME pointing to the right JDK location, but I have not tried that though because I dont want environment variables for each JDK version.

My environment was prior tooling such as Jenkins and was running with batch files (I know, I'm old). So those batch files (and their sub-batch files) are using environment variables. This was my piece of groovy script which injects environment variables. The names and parameters used are dummy ones.

// The process/batch which uses environment variables
def buildLabel = "SomeVersionNr"
def script = "startBuild.bat"
def processBuilder = new ProcessBuilder(script, buildLabel)

//Inject our environment variables
Map<String, String> env = processBuilder.environment()
env.put("ProjectRoot", "someLocation")
env.put("SomeVar", "Some")

Process p = processBuilder.start()
p.waitFor()

Of course if you set Jenkins up from scratch you would probably do it differently and share the variables in another way, or pass parameters around but this might come handy.

I know it's an old question but I faced the same problem and saw that none of the answers worked properly - specifically weeding out numbers (1,200,345,etc..) from dates, which is the original question. Here is a rather unorthodox method I could think of and it seems to work. Please point out if there are cases where it will fail.

if(sDate.toString() == parseInt(sDate).toString()) return false;

This is the line to weed out numbers. Thus, the entire function could look like:

function isDate(sDate) {  _x000D_
  if(sDate.toString() == parseInt(sDate).toString()) return false; _x000D_
  var tryDate = new Date(sDate);_x000D_
  return (tryDate && tryDate.toString() != "NaN" && tryDate != "Invalid Date");  _x000D_
}_x000D_
_x000D_
console.log("100", isDate(100));_x000D_
console.log("234", isDate("234"));_x000D_
console.log("hello", isDate("hello"));_x000D_
console.log("25 Feb 2018", isDate("25 Feb 2018"));_x000D_
console.log("2009-11-10T07:00:00+0000", isDate("2009-11-10T07:00:00+0000"));

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

set height: auto; If you want to have minimum height to x then you can write

height:auto;
min-height:30px;
height:auto !important;        /* for IE as it does not support min-height */
height:30px;                   /* for IE as it does not support min-height */

If you don't want to use Windows Forms nor edit manifest files, I came up with a very simple hack using WPF's SaveAs dialog for actually selecting a directory.

No using directive needed, you may simply copy-paste the code below !

It should still be very user-friendly and most people will never notice.

The idea comes from the fact that we can change the title of that dialog, hide files, and work around the resulting filename quite easily.

It is a big hack for sure, but maybe it will do the job just fine for your usage...

In this example I have a textbox object to contain the resulting path, but you may remove the related lines and use a return value if you wish...

// Create a "Save As" dialog for selecting a directory (HACK)
var dialog = new Microsoft.Win32.SaveFileDialog();
dialog.InitialDirectory = textbox.Text; // Use current value for initial dir
dialog.Title = "Select a Directory"; // instead of default "Save As"
dialog.Filter = "Directory|*.this.directory"; // Prevents displaying files
dialog.FileName = "select"; // Filename will then be "select.this.directory"
if (dialog.ShowDialog() == true) {
    string path = dialog.FileName;
    // Remove fake filename from resulting path
    path = path.Replace("\\select.this.directory", "");
    path = path.Replace(".this.directory", "");
    // If user has changed the filename, create the new directory
    if (!System.IO.Directory.Exists(path)) {
        System.IO.Directory.CreateDirectory(path);
    }
    // Our final value is in path
    textbox.Text = path;
}

The only issues with this hack are :

• Acknowledge button still says "Save" instead of something like "Select directory", but in a case like mines I "Save" the directory selection so it still works...
• Input field still says "File name" instead of "Directory name", but we can say that a directory is a type of file...
• There is still a "Save as type" dropdown, but its value says "Directory (*.this.directory)", and the user cannot change it for something else, works for me...

Most people won't notice these, although I would definitely prefer using an official WPF way if microsoft would get their heads out of their asses, but until they do, that's my temporary fix.

Use the DATE function:

SELECT DATE(orders.date_purchased) AS date

Swift 3.0

    let image = UIImage(named:"NoConnection")!

 warningButton = UIButton(type: .system)        
    warningButton.setImage(image, for: .normal)
    warningButton.tintColor = UIColor.lightText
    warningButton.frame = CGRect(origin: CGPoint(x:-100,y:0), size: CGSize(width: 59, height: 56))

    self.addSubview(warningButton)

When I want to take into account extra characters like your commas (in my case each token may be entered with quotes), I'd do a string.replace() to change the other delimiters to blanks and then split on whitespace.

just discovered enumeratum. it's pretty amazing and equally amazing it's not more well known!

Try this:

> data[match(as.character(data$Code), selected, nomatch = FALSE), ]
    Code Value
1      A     1
2      B     2
1.1    A     1
1.2    A     1

According to Microsoft documentation about Math Constants:

The file ATLComTime.h includes math.h when your project is built in Release mode. If you use one or more of the math constants in a project that also includes ATLComTime.h, you must define _USE_MATH_DEFINES before you include ATLComTime.h.

File ATLComTime.h may be included indirectly in your project. In my case one possible order of including was the following:

project's "stdafx.h" ? <afxdtctl.h> ? <afxdisp.h> ? <ATLComTime.h> ? <math.h>

Summary

Simply prevent the default browser action:

window.addEventListener("keydown", function(e) {
    // space and arrow keys
    if([32, 37, 38, 39, 40].indexOf(e.code) > -1) {
        e.preventDefault();
    }
}, false);

If you need to support Internet Explorer or other older browsers, use e.keyCode instead of e.code, but keep in mind that keyCode is deprecated.

Original answer

I used the following function in my own game:

var keys = {};
window.addEventListener("keydown",
    function(e){
        keys[e.code] = true;
        switch(e.code){
            case 37: case 39: case 38:  case 40: // Arrow keys
            case 32: e.preventDefault(); break; // Space
            default: break; // do not block other keys
        }
    },
false);
window.addEventListener('keyup',
    function(e){
        keys[e.code] = false;
    },
false);

The magic happens in e.preventDefault();. This will block the default action of the event, in this case moving the viewpoint of the browser.

If you don't need the current button states you can simply drop keys and just discard the default action on the arrow keys:

var arrow_keys_handler = function(e) {
    switch(e.code){
        case 37: case 39: case 38:  case 40: // Arrow keys
        case 32: e.preventDefault(); break; // Space
        default: break; // do not block other keys
    }
};
window.addEventListener("keydown", arrow_keys_handler, false);

Note that this approach also enables you to remove the event handler later if you need to re-enable arrow key scrolling:

window.removeEventListener("keydown", arrow_keys_handler, false);

have you tried doing it without the JSON object and just passed two basicnamevaluepairs? also, it might have something to do with your serversettings

Update: this is a piece of code I use:

InputStream is = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate)); 

try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(connection);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        Log.d("HTTP", "HTTP: OK");
    } catch (Exception e) {
        Log.e("HTTP", "Error in http connection " + e.toString());
    }

It is possible using ogr2ogr:

(Not sure if ogr2ogr is included in postgres installation or if I got it with postgis extension.)

<meta name="language" content="Spanish">

This isn't defined in any specification (including the HTML5 draft)

<meta http-equiv="content-language" content="es">

This is a poor man's version of a real HTTP header and should really be expressed in the headers. For example:

Content-language: es
Content-type: text/html;charset=UTF-8

It says that the document is intended for Spanish language speakers (it doesn't, however mean the document is written in Spanish; it could, for example, be written in English as part of a language course for Spanish speakers).

From the spec:

The Content-Language entity-header field describes the natural language(s) of the intended audience for the enclosed entity. Note that this might not be equivalent to all the languages used within the entity-body.

If you want to state that a document is written in Spanish then use:

<html lang="es">

even simpler, adding up to String[],

use built-in filter filter(StringUtils::isNotEmpty) of org.apache.commons.lang3

import org.apache.commons.lang3.StringUtils;

    String test = "a\nb\n\nc\n";
    String[] lines = test.split("\\n", -1);


    String[]  result = Arrays.stream(lines).filter(StringUtils::isNotEmpty).toArray(String[]::new);
    System.out.println(Arrays.toString(lines));
    System.out.println(Arrays.toString(result));

and output: [a, b, , c, ] [a, b, c]

Use <meta charset="utf-8" /> for web browsers when using HTML5.

Use <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> when using HTML4 or XHTML, or for outdated dom parsers, like DOMDocument in php 5.3

Or with standard Java API you can use java.util.Properties:

Properties props = new Properties();
try (FileInputStream in = new FileInputStream(path)) {
    props.load(in);
}

This is if you are building a package and you are finding error in imports. I learnt it the hard way.The answer isn't to add the package to python path or to do it programatically (what if your module gets installed and your command adds it again?) thats a bad way.

The right thing to do is: 1) Use virtualenv pyvenv-3.4 or something similar 2) Activate the development mode - $python setup.py develop

Adding my own implementation of Hermann's answer. I needed OS detection so that's been added. Also includes some ES6 code (because we have a transpiler) that you might need to ES5-ify.

detectClient() {
    let nav = navigator.appVersion,
        os = 'unknown',
        client = (() => {
            let agent = navigator.userAgent,
                engine = agent.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [],
                build;

            if(/trident/i.test(engine[1])){
                build = /\brv[ :]+(\d+)/g.exec(agent) || [];
                return {browser:'IE', version:(build[1] || '')};
            }

            if(engine[1] === 'Chrome'){
                build = agent.match(/\bOPR\/(\d+)/);

                if(build !== null) {
                    return {browser: 'Opera', version: build[1]};
                }
            }

            engine = engine[2] ? [engine[1], engine[2]] : [navigator.appName, nav, '-?'];

            if((build = agent.match(/version\/(\d+)/i)) !== null) {
                engine.splice(1, 1, build[1]);
            }

            return {
              browser: engine[0],
              version: engine[1]
            };
        })();

    switch (true) {
        case nav.indexOf('Win') > -1:
            os = 'Windows';
        break;
        case nav.indexOf('Mac') > -1:
            os = 'MacOS';
        break;
        case nav.indexOf('X11') > -1:
            os = 'UNIX';
        break;
        case nav.indexOf('Linux') > -1:
            os = 'Linux';
        break;
    }        

    client.os = os;
    return client;
}

Returns: Object {browser: "Chrome", version: "50", os: "UNIX"}

It would be easier to recreate the data frame. This would also interpret the columns types from scratch.

headers = df.iloc[0]
new_df  = pd.DataFrame(df.values[1:], columns=headers)

Efran Cobisi's suggestion of using an Auto Mapper is a good one. I have used Auto Mapper for a while and it worked well, until I found the much faster alternative, Mapster.

Given a large list or IEnumerable, Mapster outperforms Auto Mapper. I found a benchmark somewhere that showed Mapster being 6 times as fast, but I could not find it again. You could look it up and then, if it is suits you, use Mapster.

As an alternate option, if you have the Sqlite Database Browser and are more inclined to a GUI solution, you can edit the sqlite_sequence table where field name is the name of your table. Double click the cell for the field seq and change the value to 0 in the dialogue box that pops up.

Although this question isn't quite new and an answer was already chosen, I would like to share another nice approach.

Using the paramiko library - a pure python implementation of SSH2 - your python script can connect to a remote host via SSH, copy itself (!) to that host and then execute that copy on the remote host. Stdin, stdout and stderr of the remote process will be available on your local running script. So this solution is pretty much independent of an IDE.

On my local machine, I run the script with a cmd-line parameter 'deploy', which triggers the remote execution. Without such a parameter, the actual code intended for the remote host is run.

import sys
import os

def main():
    print os.name

if __name__ == '__main__':
    try:
        if sys.argv[1] == 'deploy':
            import paramiko

            # Connect to remote host
            client = paramiko.SSHClient()
            client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
            client.connect('remote_hostname_or_IP', username='john', password='secret')

            # Setup sftp connection and transmit this script
            sftp = client.open_sftp()
            sftp.put(__file__, '/tmp/myscript.py')
            sftp.close()

            # Run the transmitted script remotely without args and show its output.
            # SSHClient.exec_command() returns the tuple (stdin,stdout,stderr)
            stdout = client.exec_command('python /tmp/myscript.py')[1]
            for line in stdout:
                # Process each line in the remote output
                print line

            client.close()
            sys.exit(0)
    except IndexError:
        pass

    # No cmd-line args provided, run script normally
    main()

Exception handling is left out to simplify this example. In projects with multiple script files you will probably have to put all those files (and other dependencies) on the remote host.

If you want to make sure your div is not visible by default use ng-cloak class instead. It will work properly with ngShow directive:

<div><div ng-show="myvalue" class="ng-cloak">Here I am</div></div>

I think it's most convenient way to inject properties into bean is setter method.

Example:

package org.some.beans;

public class MyBean {
    Long id;
    String name;

    public void setId(Long id) {
        this.id = id;
    }

    public Long getId() {
        return id;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

Bean xml definition:

<bean id="Bean1" class="org.some.beans.MyBean">
    <property name="id" value="1"/>
    <property name="name" value="MyBean"/>
</bean>

For every named property method setProperty(value) will be invoked.

This way is especially helpful if you need more than one bean based on one implementation.

For example, if we define one more bean in xml:

<bean id="Bean2" class="org.some.beans.MyBean">
    <property name="id" value="2"/>
    <property name="name" value="EnotherBean"/>
</bean>

Then code like this:

MyBean b1 = appContext.getBean("Bean1");
System.out.println("Bean id = " + b1.getId() + " name = " + b1.getName());
MyBean b2 = appContext.getBean("Bean2");
System.out.println("Bean id = " + b2.getId() + " name = " + b2.getName());

Will print

Bean id = 1 name = MyBean
Bean id = 2 name = AnotherBean

So, in your case it should look like this:

@Repository("personDao")
public class PersonDaoImpl extends AbstractDaoImpl implements PersonDao {

    Long maxResults;

    public void setMaxResults(Long maxResults) {
        this.maxResults = maxResults;
    }

    // Now use maxResults value in your code, it will be injected on Bean creation
    public void someMethod(Long results) {
        if (results < maxResults) {
            ...
        }
    }
}

This answer is based on an article that no longer exists:

Summary of article:

"Basically, WCF is a service layer that allows you to build applications that can communicate using a variety of communication mechanisms. With it, you can communicate using Peer to Peer, Named Pipes, Web Services and so on.

You can’t compare them because WCF is a framework for building interoperable applications. If you like, you can think of it as a SOA enabler. What does this mean?

Well, WCF conforms to something known as ABC, where A is the address of the service that you want to communicate with, B stands for the binding and C stands for the contract. This is important because it is possible to change the binding without necessarily changing the code. The contract is much more powerful because it forces the separation of the contract from the implementation. This means that the contract is defined in an interface, and there is a concrete implementation which is bound to by the consumer using the same idea of the contract. The datamodel is abstracted out."

... later ...

"should use WCF when we need to communicate with other communication technologies (e,.g. Peer to Peer, Named Pipes) rather than Web Service"

Answer

You can't according to the PHP manual:

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.

Work around

But you can work around it by also setting $_COOKIE when you call setcookie():

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', 'ro');
    $_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

For safety, I always parenthesise my comparisons and space them out. That way, I don't have to rely on operator precedence:

if( 
    ((i==0) && (b==2)) 
    || 
    ((c==3) && !(f==5))

There is a lot of really helpful info posted here, but there is one thing that all the posts seem to have wrong. I could not find any 'Settings' option under 'Files', and I hunted around for 10 minutes looking through all the menus until I found the settings under 'IntelliJ IDE' -> 'Preferences'.

I don't know if I am using a differing OS version or IntelliJ version from other posters, or if it is because I am a stupid Windows user that doesn't know that settings == preferences on a mac (Did I miss the memo?), but I hope this helps you if you aren't finding the paths that other posts are suggesting.

The adb utility does have the ability to connect to a device over TCP/IP. However, adbd is not normally listening for TCP connections.

If you want to get it running, you need an engineering device (in other words, you need root). Then follow the directions in this post:

How can I connect to Android with ADB over TCP?

Since this only works on eng devices, it's not officially supported. Use at your own risk, expect bugs, etc.

Why don't you use % ?

print 4 % 2 # 0

You can simply add show.legend=FALSE to geom to suppress the corresponding legend

Well,

If you mark all involved classes as serializable you can :

public static List<T> CloneList<T>(List<T> oldList)  
{  
BinaryFormatter formatter = new BinaryFormatter();  
MemoryStream stream = new MemoryStream();  
formatter.Serialize(stream, oldList);  
stream.Position = 0;  
return (List<T>)formatter.Deserialize(stream);      
}

You're out of memory. Try adding -Xmx256m to your java command line. The 256m is the amount of memory to give to the JVM (256 megabytes). It usually defaults to 64m.

Browsers now warn for the use of synchronous XHR. MDN says this was implemented recently:

Starting with Gecko 30.0 (Firefox 30.0 / Thunderbird 30.0 / SeaMonkey 2.27)

https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Synchronous_and_Asynchronous_Requests#Synchronous_request

Here's how the change got implemented in Firefox and Chromium:

• https://bugzilla.mozilla.org/show_bug.cgi?id=969671
• http://src.chromium.org/viewvc/blink?view=revision&revision=184788

As for Chrome people report this started happening somewhere around version 39. I'm not sure how to link a revision/changeset to a particular version of Chrome.

Yes, it happens when jQuery appends markup to the page including script tags that load external js files. You can reproduce it with something like this:

$('body').append('<script src="foo.js"></script>');

I guess jQuery will fix this in some future version. Until then we can either ignore it or use A. Wolff's suggestion above.

for(n in 1:5) {
  if(n==3) next # skip 3rd iteration and go to next iteration
  cat(n)
}

I did define all the variables that was the first thing I checked. I know it's not required in PHP, but old habits die hard. Then I sanatized the info like this:

if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (empty($_POST["name1"])) {
    $name1Err = " First Name is a required field.";
  } else {
      $name1 = test_input($_POST["name1"]);
    // check if name only contains letters and whitespace
      if (!preg_match("/^[a-zA-Z ]*$/",$name1)) {
      $name1Err = "Only letters and white space allowed";

of course test_input is another function that does a trim, strilashes, and htmlspecialchars. I think the input is pretty well sanitized. Not trying to be rude just showing what I did. When it came to the email I also checked to see if it was the proper format. I think the real answer is in the fact that some variables are local and some are global. I have got it working without errors for now so, while I'm extremely busy right now I'll accept shutting off errors as my answer. Don't worry I'll figure it out it's just not vitally important right now!

Is your MySQL server version 5.5.3 or greater?

The utf8mb4, utf16, and utf32 character sets were added in MySQL 5.5.3.

http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-sets.html

You can change following parameters as you want:

<your_crumb_data>
<username>
<password>
<your_jenkins_url>
<your_remote_api_name>
<parameterA>
<parameterB>
<val_parameter_A>

SOAP 1.1 uses namespace http://schemas.xmlsoap.org/wsdl/soap/

SOAP 1.2 uses namespace http://schemas.xmlsoap.org/wsdl/soap12/

The wsdl is able to define operations under soap 1.1 and soap 1.2 at the same time in the same wsdl. Thats useful if you need to evolve your wsdl to support new functionality that requires soap 1.2 (eg. MTOM), in this case you dont need to create a new service but just evolve the original one.

In the background a property is compiled into methods. So a Name property is compiled into get_Name() and set_Name(string value). You can see this if you study the compiled code. So there is a (very) small performance overhead when using them. Normally you will always use a Property if you expose a field to the outside, and you will often use it internally if you need to do validation of the value.

You will need to build the jar file first. Here is the syntax to run the main class from a jar file.

java -jar path/to/your/jarfile.jar fully.qualified.package.Application 

Having spent lot of time trying to fix this. I had no luck with any solution provide here or elsewhere.

But then later realised it wasn't so much as just solving the issue. But you also need to RESTART the VSCODE for it to take affect.

#include <string.h>
...
char otherString[6]; // note 6, not 5, there's one there for the null terminator
...
strncpy(otherString, someString, 5);
otherString[5] = '\0'; // place the null terminator

You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.

You have two options:

• Grant write permissions to the folder to the user or group you log in with (myuser), or change the ownership of the folder to the user, or

• Disable a transfer to temporary file.

  In Preferences, go to Transfer > Endurance page and in Enable transfer resume/transfer to temporary file name for select Disable:

  

Just update your eclipse.ini file (you can find it in the root-directory of eclipse) by this:

-vm
path/javaw.exe

for example:

-vm 
C:/Program Files/Java/jdk1.7.0_09/jre/bin/javaw.exe

The ... can only be used in JDK 1.5 or later. If you are using JDK 4 or lower, use this code:'

public static int[] addElement(int[] original, int newelement) {
    int[] nEw = new int[original.length + 1];
    System.arraycopy(original, 0, nEw, 0, original.length);
    nEw[original.length] = newelement;
}

otherwise (JDK 5 or higher):

public static int[] addElement(int[] original, int... elements) { // This can add multiple elements at once; addElement(int[], int) will still work though.
    int[] nEw = new int[original.length + elements.length];
    System.arraycopy(original, 0, nEw, 0, original.length);
    System.arraycopy(elements, 0, nEw, original.length, elements.length);
    return nEw;
}

Of course, as many have mentioned above, you could use a Collection or an ArrayList, which allows you to use the .add() method.

If you are using JQuery then put the javascript wherever you find it best and use $(document).ready() to ensure that things are loaded properly before executing any functions.

On a side note: I like all my script tags in the <head> section as that seems to be the cleanest place.

You could do it like this.

jsFiddle

JS

var select = document.getElementById('mySelect');
select.onchange = function () {
    select.className = this.options[this.selectedIndex].className;
}

CSS

.redText {
    background-color:#F00;
}
.greenText {
    background-color:#0F0;
}
.blueText {
    background-color:#00F;
}

You could use option { background-color: #FFF; } if you want the list to be white.

HTML

<select id="mySelect" class="greenText">
    <option class="greenText" value="apple" >Apple</option>
    <option class="redText"   value="banana" >Banana</option>
    <option class="blueText" value="grape" >Grape</option>
</select>

Since this is a select it doesn't really make sense to use .yellowText as none selected if that's what you were getting at as something must be selected.

You can create a extension method:

public static IEnumerable<T> Do<T>(this IEnumerable<T> self, Action<T> action) {
    foreach(var item in self) {
        action(item);
        yield return item;
    }
}

And then use it in code:

listofCompany.Do(d=>d.Id = 1);
listofCompany.Where(d=>d.Name.Contains("Inc")).Do(d=>d.Id = 1);

Ultimate way to do this.

ngOnInit() {
  this.interPretationForm.controls.InterpretationType.valueChanges.takeWhile(()=> this.alive).subscribe(val =>{
    console.log(val); // You check code. it will be executed every time value change.
  })
}

Below code works for me

   public static void sftpsript(String filepath) {

 try {
  String user ="demouser"; // username for remote host
  String password ="demo123"; // password of the remote host

   String host = "demo.net"; // remote host address
  JSch jsch = new JSch();
  Session session = jsch.getSession(user, host);
  session.setPassword(password);
  session.connect();

  ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
  sftpChannel.connect();

  sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
  sftpChannel.disconnect();
  session.disconnect();
 }catch(Exception ex){
     ex.printStackTrace();
 }
   }

OR using StrictHostKeyChecking as "NO" (security consequences)

public static void sftpsript(String filepath) {

 try {
  String user ="demouser"; // username for remote host
  String password ="demo123"; // password of the remote host

   String host = "demo.net"; // remote host address
  JSch jsch = new JSch();
   Session session = jsch.getSession(user, host, 22);
   Properties config = new Properties();
   config.put("StrictHostKeyChecking", "no");
   session.setConfig(config);;
   session.setPassword(password);
   System.out.println("user=="+user+"\n host=="+host);
   session.connect();

  ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
  sftpChannel.connect();

  sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
  sftpChannel.disconnect();
  session.disconnect();
 }catch(Exception ex){
     ex.printStackTrace();
 }
   }

Python 3.6 and newer have literal string interpolation using f-strings:

name='world'
print(f"Hello {name}!")

A. Grab file data from the file field

The first thing to do is bind a function to the change event on your file field and a function for grabbing the file data:

// Variable to store your files
var files;

// Add events
$('input[type=file]').on('change', prepareUpload);

// Grab the files and set them to our variable
function prepareUpload(event)
{
  files = event.target.files;
}

This saves the file data to a file variable for later use.

B. Handle the file upload on submit

When the form is submitted you need to handle the file upload in its own AJAX request. Add the following binding and function:

$('form').on('submit', uploadFiles);

// Catch the form submit and upload the files
function uploadFiles(event)
{
  event.stopPropagation(); // Stop stuff happening
    event.preventDefault(); // Totally stop stuff happening

// START A LOADING SPINNER HERE

// Create a formdata object and add the files
var data = new FormData();
$.each(files, function(key, value)
{
    data.append(key, value);
});

$.ajax({
    url: 'submit.php?files',
    type: 'POST',
    data: data,
    cache: false,
    dataType: 'json',
    processData: false, // Don't process the files
    contentType: false, // Set content type to false as jQuery will tell the server its a query string request
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            submitForm(event, data);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
        // STOP LOADING SPINNER
    }
});
}

What this function does is create a new formData object and appends each file to it. It then passes that data as a request to the server. 2 attributes need to be set to false:

• processData - Because jQuery will convert the files arrays into strings and the server can't pick it up.
• contentType - Set this to false because jQuery defaults to application/x-www-form-urlencoded and doesn't send the files. Also setting it to multipart/form-data doesn't seem to work either.

C. Upload the files

Quick and dirty php script to upload the files and pass back some info:

<?php // You need to add server side validation and better error handling here

$data = array();

if(isset($_GET['files']))
{  
$error = false;
$files = array();

$uploaddir = './uploads/';
foreach($_FILES as $file)
{
    if(move_uploaded_file($file['tmp_name'], $uploaddir .basename($file['name'])))
    {
        $files[] = $uploaddir .$file['name'];
    }
    else
    {
        $error = true;
    }
}
$data = ($error) ? array('error' => 'There was an error uploading your files') : array('files' => $files);
}
else
{
    $data = array('success' => 'Form was submitted', 'formData' => $_POST);
}

echo json_encode($data);

?>

IMP: Don't use this, write your own.

D. Handle the form submit

The success method of the upload function passes the data sent back from the server to the submit function. You can then pass that to the server as part of your post:

function submitForm(event, data)
{
  // Create a jQuery object from the form
$form = $(event.target);

// Serialize the form data
var formData = $form.serialize();

// You should sterilise the file names
$.each(data.files, function(key, value)
{
    formData = formData + '&filenames[]=' + value;
});

$.ajax({
    url: 'submit.php',
    type: 'POST',
    data: formData,
    cache: false,
    dataType: 'json',
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            console.log('SUCCESS: ' + data.success);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
    },
    complete: function()
    {
        // STOP LOADING SPINNER
    }
});
}

Final note

This script is an example only, you'll need to handle both server and client side validation and some way to notify users that the file upload is happening. I made a project for it on Github if you want to see it working.

Referenced From

public void keyReleased(KeyEvent e)
{
    int key=e.getKeyCode();
    if(e.getSource()==textField)
    {
        if(key==KeyEvent.VK_ENTER)
        { 
            Toolkit.getDefaultToolkit().beep();
            textField_1.requestFocusInWindow();                     
        }
    }

To write logic for 'Enter press' in JTextField, it is better to keep logic inside the keyReleased() block instead of keyTyped() & keyPressed().

Very old thread but a simpler take :)

Sub firstBlank(c) 'as letter
    MsgBox (c & Split(Range(c & ":" & c).Find("", LookIn:=xlValues).address, "$")(2))
End Sub
Sub firstBlank(c) 'as number
    cLet = Split(Cells(1, c).address, "$")(1)
    MsgBox (cLet & Split(Range(cLet & ":" & cLet).Find("", LookIn:=xlValues).address, "$")(2))
End Sub

This code makes a window with the conditions that the user cannot change the dimensions of the Tk() window, and also disables the maximise button.

import tkinter as tk

root = tk.Tk()
root.resizable(width=False, height=False)
root.mainloop()

Within the program you can change the window dimensions with @Carpetsmoker's answer, or by doing this:

root.geometry('{}x{}'.format(<widthpixels>, <heightpixels>))

It should be fairly easy for you to implement that into your code. :)

as per @Jon Skeet 's comment, you should use a XmlReader only if your file is very big. Here's how to use it. Assuming you have a Book class

public class Book {
    public string Title {get; set;}
    public string Author {get; set;}
}

you can read the XML file line by line with a small memory footprint, like this:

public static class XmlHelper {
    public static IEnumerable<Book> StreamBooks(string uri) {
        using (XmlReader reader = XmlReader.Create(uri)) {
            string title = null;
            string author = null;

            reader.MoveToContent();
            while (reader.Read()) {
                if (reader.NodeType == XmlNodeType.Element
                    && reader.Name == "Book") {
                    while (reader.Read()) {
                        if (reader.NodeType == XmlNodeType.Element &&
                            reader.Name == "Title") {
                            title = reader.ReadString();
                            break;
                        }
                    }
                    while (reader.Read()) {
                        if (reader.NodeType == XmlNodeType.Element &&
                            reader.Name == "Author") {
                            author =reader.ReadString();
                            break;
                        }
                    }
                    yield return new Book() {Title = title, Author = author};
                }
            }       
        }
    }

Example of usage:

string uri = @"c:\test.xml"; // your big XML file

foreach (var book in XmlHelper.StreamBooks(uri)) {
    Console.WriteLine("Title, Author: {0}, {1}", book.Title, book.Author);  
}

QueryTypes is the canonical answer as of EF Core 2.1, but there is another way I have used when migrating from a database first approach (the view is already created in the database):

• define the model to match view columns (either match model class name to view name or use Table attribute. Ensure [Key] attribute is applied to at least one column, otherwise data fetch will fail
• add DbSet in your context
• add migration (Add-Migration)
• remove or comment out code for creation/drop of the "table" to be created/dropped based on provided model
• update database (Update-Database)

You have four choices to supply a password:

1. Set the PGPASSWORD environment variable. For details see the manual:
   http://www.postgresql.org/docs/current/static/libpq-envars.html
2. Use a .pgpass file to store the password. For details see the manual:
   http://www.postgresql.org/docs/current/static/libpq-pgpass.html
3. Use "trust authentication" for that specific user: http://www.postgresql.org/docs/current/static/auth-methods.html#AUTH-TRUST
4. Since PostgreSQL 9.1 you can also use a connection string:
   https://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING

If you only need the bool result, just use the return value and ignore the out parameter.

bool successfullyParsed = int.TryParse(str, out ignoreMe);
if (successfullyParsed){
    // ...
}

Edit: Meanwhile you can also have a look at the original source code:

System.Int32.TryParse

If i want to know how something is actually implemented, i'm using ILSpy to decompile the .NET-code.

What are -moz- and -webkit-?

CSS properties starting with -webkit-, -moz-, -ms- or -o- are called vendor prefixes.

Why do different browsers add different prefixes for the same effect?

A good explanation of vendor prefixes comes from Peter-Paul Koch of QuirksMode:

Originally, the point of vendor prefixes was to allow browser makers to start supporting experimental CSS declarations.

Let's say a W3C working group is discussing a grid declaration (which, incidentally, wouldn't be such a bad idea). Let's furthermore say that some people create a draft specification, but others disagree with some of the details. As we know, this process may take ages.

Let's furthermore say that Microsoft as an experiment decides to implement the proposed grid. At this point in time, Microsoft cannot be certain that the specification will not change. Therefore, instead of adding the grid to its CSS, it adds -ms-grid.

The vendor prefix kind of says "this is the Microsoft interpretation of an ongoing proposal." Thus, if the final definition of the grid is different, Microsoft can add a new CSS property grid without breaking pages that depend on -ms-grid.

UPDATE AS OF THE YEAR 2016

As this post 3 years old, it's important to mention that now most vendors do understand that these prefixes are just creating un-necessary duplicate code and that the situation where you need to specify 3 different CSS rules to get one effect working in all browser is an unwanted one.

As mentioned in this glossary about Mozilla's view on Vendor Prefix on May 3, 2016,

Browser vendors are now trying to get rid of vendor prefix for experimental features. They noticed that Web developers were using them on production Web sites, polluting the global space and making it more difficult for underdogs to perform well.

For example, just a few years ago, to set a rounded corner on a box you had to write:

-moz-border-radius: 10px 5px;
-webkit-border-top-left-radius: 10px;
-webkit-border-top-right-radius: 5px;
-webkit-border-bottom-right-radius: 10px;
-webkit-border-bottom-left-radius: 5px;
border-radius: 10px 5px;

But now that browsers have come to fully support this feature, you really only need the standardized version:

border-radius: 10px 5px;

Finding the right rules for all browsers

As still there's no standard for common CSS rules that work on all browsers, you can use tools like caniuse.com to check support of a rule across all major browsers.

You can also use pleeease.io/play. Pleeease is a Node.js application that easily processes your CSS. It simplifies the use of preprocessors and combines them with best postprocessors. It helps create clean stylesheets, support older browsers and offers better maintainability.

Input:

a {
  column-count: 3;
  column-gap: 10px;
  column-fill: auto;
}

Output:

a {
  -webkit-column-count: 3;
     -moz-column-count: 3;
          column-count: 3;
  -webkit-column-gap: 10px;
     -moz-column-gap: 10px;
          column-gap: 10px;
  -webkit-column-fill: auto;
     -moz-column-fill: auto;
          column-fill: auto;
}

These are different Form content types defined by W3C. If you want to send simple text/ ASCII data, then x-www-form-urlencoded will work. This is the default.

But if you have to send non-ASCII text or large binary data, the form-data is for that.

You can use Raw if you want to send plain text or JSON or any other kind of string. Like the name suggests, Postman sends your raw string data as it is without modifications. The type of data that you are sending can be set by using the content-type header from the drop down.

Binary can be used when you want to attach non-textual data to the request, e.g. a video/audio file, images, or any other binary data file.

Refer to this link for further reading: Forms in HTML documents

left: initial

This will also set left back to the browser default.

But important to know property: initial is not supported in IE.

If you use ng-show or ng-hide the content (eg. thumbnails from server) will be loaded irrespective of the value of expression but will be displayed based on the value of the expression.

If you use ng-if the content will be loaded only if the expression of the ng-if evaluates to truthy.

Using ng-if is a good idea in a situation where you are going to load data or images from the server and show those only depending on users interaction. This way your page load will not be blocked by unnecessary nw intensive tasks.

Try this:

package example.spin.spinnerexample;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener{

    String[] bankNames={"BOI","SBI","HDFC","PNB","OBC"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //Getting the instance of Spinner and applying OnItemSelectedListener on it
        Spinner spin = (Spinner) findViewById(R.id.simpleSpinner);
        spin.setOnItemSelectedListener(this);

        //Creating the ArrayAdapter instance having the bank name list
        ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_spinner_item,bankNames);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        //Setting the ArrayAdapter data on the Spinner
        spin.setAdapter(aa);
    }


    //Performing action onItemSelected and onNothing selected
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int position,long id) {
        Toast.makeText(getApplicationContext(), bankNames[position], Toast.LENGTH_LONG).show();
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }
}

activity_main.xml:-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <Spinner
        android:id="@+id/simpleSpinner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="100dp" />

</RelativeLayout>

by using Listbuffer we can save data into single file:

import java.io.FileWriter
import org.apache.spark.sql.SparkSession
import scala.collection.mutable.ListBuffer
    val text = spark.read.textFile("filepath")
    var data = ListBuffer[String]()
    for(line:String <- text.collect()){
      data += line
    }
    val writer = new FileWriter("filepath")
    data.foreach(line => writer.write(line.toString+"\n"))
    writer.close()

Simplest Solution:

I have used an AngularJS service.

Step1: I have created an AngularJS service named SharedDataService.

myApp.service('SharedDataService', function () {
     var Person = {
        name: ''

    };
    return Person;
});

Step2: Create two controllers and use the above created service.

//First Controller
myApp.controller("FirstCtrl", ['$scope', 'SharedDataService',
   function ($scope, SharedDataService) {
   $scope.Person = SharedDataService;
   }]);

//Second Controller
myApp.controller("SecondCtrl", ['$scope', 'SharedDataService',
   function ($scope, SharedDataService) {
   $scope.Person = SharedDataService;
   }]);

Step3: Simply use the created controllers in the view.

<body ng-app="myApp">

<div ng-controller="FirstCtrl">
<input type="text" ng-model="Person.name">
<br>Input is : <strong>{{Person.name}}</strong>
</div>

<hr>

<div ng-controller="SecondCtrl">
Input should also be here: {{Person.name}}
</div>

</body>

The Servlet 3.0 spec doesn't seem to provide a hint on how a container should order filters that have been declared via annotations. It is clear how about how to order filters via their declaration in the web.xml file, though.

Be safe. Use the web.xml file order filters that have interdependencies. Try to make your filters all order independent to minimize the need to use a web.xml file.

A .pl is a single script.

In .pm (Perl Module) you have functions that you can use from other Perl scripts:

A Perl module is a self-contained piece of Perl code that can be used by a Perl program or by other Perl modules. It is conceptually similar to a C link library, or a C++ class.

It might be, because your span element sets is side as width as its content. if you have a div with 500px width and text-align center, and you enter a span tag it should be aligned in the center. So your problem might be a CSS one. Install Firebug at Firefox and check the style attributes your span or div object has.

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

You're probably passing null value if you're loading the coordinates dynamically, set a check before you call the map loader ie: if(mapCords){loadMap}

have you tried something like this:

if [ $# -eq 0 ] || [ $# -gt 1 ] 
then
 echo "$#"
fi

To make sure it's a simulator issue, see if you can connect to the simulator with a brand new project without changing any code. Try the tab bar template.

If you think it's a simulator issue, press the iOS Simulator menu. Select "Reset Content and Settings...". Press "Reset."

I can't see your XIB and what @properties you have connected in Interface Builder, but it could also be that you're not loading your window, or that your window is not loading your view controller.

use .empty()

 $('select').empty().append('whatever');

you can also use .html() but note

When .html() is used to set an element's content, any content that was in that element is completely replaced by the new content. Consider the following HTML:

alternative: --- If you want only option elements to-be-remove, use .remove()

$('select option').remove();

Alciende's answer didn't quite work for me in Safari for whatever reason just now, but did after a minor modification:

function textAreaAdjust(o) {
    o.style.height = "1px";
    setTimeout(function() {
        o.style.height = (o.scrollHeight)+"px";
    }, 1);
}

Hope this helps someone

It depends what is the character and what encoding it is in:

• An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.

• An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).

• A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).

• A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.

• A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).

• An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.

• The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.

That would mean that there are between 0.03125 and 0.125 characters in a bit.

DataView view = new DataView();
view.Table = DataSet1.Tables["Suppliers"];
view.RowFilter = "City = 'Berlin'";
view.RowStateFilter = DataViewRowState.ModifiedCurrent;
view.Sort = "CompanyName DESC";

// Simple-bind to a TextBox control
Text1.DataBindings.Add("Text", view, "CompanyName");

Remove the first / in the path. Also you don't need type="text/javascript" anymore in HTML5.

I faced this issue, when I was supplying the executable folder with a, by the .exe requested DLL. In my case, the DLL I supplied to the .exe was searching for another necessary DLL which was not available. The searching DLL was not capable of telling that it can not find the necessary DLL.

You might check the DLLs you're loading and the dependencies of these DLL's.

I prepared a piece of code to show you how to use the task for some of these scenarios.

    // method to run tasks in a parallel 
    public async Task RunMultipleTaskParallel(Task[] tasks) {

        await Task.WhenAll(tasks);
    }
    // methode to run task one by one 
    public async Task RunMultipleTaskOneByOne(Task[] tasks)
    {
        for (int i = 0; i < tasks.Length - 1; i++)
            await tasks[i];
    }
    // method to run i task in parallel 
    public async Task RunMultipleTaskParallel(Task[] tasks, int i)
    {
        var countTask = tasks.Length;
        var remainTasks = 0;
        do
        {
            int toTake = (countTask < i) ? countTask : i;
            var limitedTasks = tasks.Skip(remainTasks)
                                    .Take(toTake);
            remainTasks += toTake;
            await RunMultipleTaskParallel(limitedTasks.ToArray());
        } while (remainTasks < countTask);
    }

td:hover{

}

I think this is what are you looking for.

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

A new twist on an old favorite:

public bool IsWithinRange(int number, int topOfRange, int bottomOfRange, bool includeBoundaries) {
    if (includeBoundaries)
        return number <= topOfRange && number >= bottomOfRange;
    return number < topOfRange && number > bottomOfRange;
}

Use:

import color

class Color(color.Color):
    ...

If this were Python 2.x, you would also want to derive color.Color from object, to make it a new-style class:

class Color(object):
    ...

This is not necessary in Python 3.x.

Check if the snippets have <tabTrigger> attributes that start with special characters. If they do, they won't show up in the autocomplete box. This is currently a problem on Windows with the available jQuery plugins.

See my answer on this thread for more details.

You were correct to use WaitForSeconds. But I suspect that you tried using it without coroutines. That's how it should work:

public void SomeMethod()
{
    StartCoroutine(SomeCoroutine());
}

private IEnumerator SomeCoroutine()
{
    TextUI.text = "Welcome to Number Wizard!";
    yield return new WaitForSeconds (3);
    TextUI.text = ("The highest number you can pick is " + max);
    yield return new WaitForSeconds (3);
    TextUI.text = ("The lowest number you can pick is " + min);
}

Method 1:

list(set([val for idx, val in enumerate(input_list) if val in input_list[idx+1:]]))

Explanation: [val for idx, val in enumerate(input_list) if val in input_list[idx+1:]] is a list comprehension, that returns an element, if the same element is present from it's current position, in list, the index.

Example: input_list = [42,31,42,31,3,31,31,5,6,6,6,6,6,7,42]

starting with the first element in list, 42, with index 0, it checks if the element 42, is present in input_list[1:] (i.e., from index 1 till end of list) Because 42 is present in input_list[1:], it will return 42.

Then it goes to the next element 31, with index 1, and checks if element 31 is present in the input_list[2:] (i.e., from index 2 till end of list), Because 31 is present in input_list[2:], it will return 31.

similarly it goes through all the elements in the list, and will return only the repeated/duplicate elements into a list.

Then because we have duplicates, in a list, we need to pick one of each duplicate, i.e. remove duplicate among duplicates, and to do so, we do call a python built-in named set(), and it removes the duplicates,

Then we are left with a set, but not a list, and hence to convert from a set to list, we use, typecasting, list(), and that converts the set of elements to a list.

Method 2:

def dupes(ilist):
    temp_list = [] # initially, empty temporary list
    dupe_list = [] # initially, empty duplicate list
    for each in ilist:
        if each in temp_list: # Found a Duplicate element
            if not each in dupe_list: # Avoid duplicate elements in dupe_list
                dupe_list.append(each) # Add duplicate element to dupe_list
        else: 
            temp_list.append(each) # Add a new (non-duplicate) to temp_list

    return dupe_list

Explanation: Here We create two empty lists, to start with. Then keep traversing through all the elements of the list, to see if it exists in temp_list (initially empty). If it is not there in the temp_list, then we add it to the temp_list, using append method.

If it already exists in temp_list, it means, that the current element of the list is a duplicate, and hence we need to add it to dupe_list using append method.

The validate_required function seems to expect an HTML form control (e.g, text input field) as first argument, and check whether there is a value there at all. That is not what you want in this case.

Also, when you write ['password'].value, you create a new array of length one, containing the string 'password', and then read the non-existing property "value" from it, yielding the undefined value.

What you may want to try instead is:

if (password.value != cpassword.value) { cpassword.focus(); return false; }

(You also need to write the error message somehow, but I can't see from your code how that is done.).

My solution on Windows 10 was just to stop IIS (Internet Information Services).

You put it as =(B0+4)/($A$0)

You can also go across WorkSheets with Sheet1!$a$0

I had the same problem. Here's what I figured out:

=BDP(A1&"@BGN Corp", "Issuer_parent_eqy_ticker")

A1 being the ISINs. This will return the ticker number. Then just use the ticker number to get the price.

In addition to Tony's answer, if you are looking to find out where your PL/SQL program is spending it's time, it is also worth checking out this part of the Oracle PL/SQL documentation.

1. Java code "BlockingQueue" which has synchronized put and get method.
2. Java code "Producer" , producer thread to produce data.
3. Java code "Consumer" , consumer thread to consume the data produced.
4. Java code "ProducerConsumer_Main", main function to start the producer and consumer thread.

BlockingQueue.java

public class BlockingQueue 
{
    int item;
    boolean available = false;

    public synchronized void put(int value) 
    {
        while (available == true)
        {
            try 
            {
                wait();
            } catch (InterruptedException e) { 
            } 
        }

        item = value;
        available = true;
        notifyAll();
    }

    public synchronized int get()
    {
        while(available == false)
        {
            try
            {
                wait();
            }
            catch(InterruptedException e){
            }
        }

        available = false;
        notifyAll();
        return item;
    }
}

Consumer.java

package com.sukanya.producer_Consumer;

public class Consumer extends Thread
{
    blockingQueue queue;
    private int number;
    Consumer(BlockingQueue queue,int number)
    {
        this.queue = queue;
        this.number = number;
    }

    public void run()
    {
        int value = 0;

        for (int i = 0; i < 10; i++) 
        {
            value = queue.get();
            System.out.println("Consumer #" + this.number+ " got: " + value);
        }
    }
}

ProducerConsumer_Main.java

package com.sukanya.producer_Consumer;

public class ProducerConsumer_Main 
{
    public static void main(String args[])
    {
        BlockingQueue queue = new BlockingQueue();
        Producer producer1 = new Producer(queue,1);
        Consumer consumer1 = new Consumer(queue,1);
        producer1.start();
        consumer1.start();
    }
}

Actually, this has nothing to do with the usual Windows / Unix \r\n vs \n issue. The TELNET procotol itself defines \r\n as the end-of-line sequence, independently of the operating system. See RFC854.

traceback.format_exc() or sys.exc_info() will yield more info if that's what you want.

import traceback
import sys

try:
    do_stuff()
except Exception:
    print(traceback.format_exc())
    # or
    print(sys.exc_info()[2])

Just put "?autoplay=1" in the url the video will autoload.

So your url would be: http://www.youtube.com/embed/JW5meKfy3fY?autoplay=1

In case you wanna disable autoplay, just make 1 to 0 as ?autoplay=0

You'll need to generate the SQL content dynamically:

declare @tablename varchar(50)

set @tablename = 'test'

declare @sql varchar(500)

set @sql = 'select * from ' + @tablename

exec (@sql)

It is all because of the ECMA specs ... "0" == false because of the rules specified here http://ecma262-5.com/ELS5_HTML.htm#Section_11.9.3 ...And if ('0') evaluates to true because of the rules specified here http://ecma262-5.com/ELS5_HTML.htm#Section_12.5

the problem is when you do

def __init__(self, user, *args, **kwargs):
    super(waypointForm, self).__init__(*args, **kwargs)
    self.fields['waypoints'] = forms.ChoiceField(choices=[ (o.id, str(o)) for o in Waypoint.objects.filter(user=user)])

in a update request, the previous value will lost!

The answer here is not clear, so I wanted to add more detail.

Using the link provided above, I performed the following step.

In my XML config manager I changed the "Provider" to SQLOLEDB.1 rather than SQLNCLI.1. This got me past this error.

This information is available at the link the OP posted in the Answer.

The link the got me there: http://social.msdn.microsoft.com/Forums/en-US/sqlintegrationservices/thread/fab0e3bf-4adf-4f17-b9f6-7b7f9db6523c/

This can happen when the owner of the SQLite file itself is not the same as the user running the script. Similar errors can occur if the entire directory path (meaning each directory along the way) can't be written to.

Who owns the SQLite file? You?

Who is the script running as? Apache or Nobody?

1. Set up your routes to accept data

{
    path: 'some-route',
    loadChildren: 
      () => import(
        './some-component/some-component.module'
      ).then(
        m => m.SomeComponentModule
      ),
    data: {
      key: 'value',
      ...
    },
}

2. Navigate to route:

From HTML:

<a [routerLink]=['/some-component', { key: 'value', ... }> ... </a>

Or from Typescript:

import {Router} from '@angular/router';

...

 this.router.navigate(
    [
       '/some-component',
       {
          key: 'value',
          ...
       }
    ]
 );

3. Get data from route

import {ActivatedRoute} from '@angular/router';

...

this.value = this.route.snapshot.params['key'];

It also depend on how you style your site with bootstrap. In my example, I am using col-md-12 for my video div, and add class col-sm-12 for the iframe, so when resize to smaller screen, the video will not view squeezed. I add also height to the iframe:

<div class="col-md-12">
<iframe class="col-sm-12" height="333" frameborder="0" wmode="Opaque" allowfullscreen="" src="https://www.youtube.com/embed/oqDRPoPDehE?wmode=transparent">
</div>

I'm sure there's some nice library that does this sort of thing already for you... But to just stick with the approach you're already going with, Map#entrySet gives you a combined Object with the key and the value. So something like:

for (Map.Entry<String, Object> entry : map.entrySet()) {
    System.out.println(entry.getKey() + ":" + entry.getValue().toString());
}

will do what you're after.

If you're using java 8, there's also the new streaming approach.

map.forEach((key, value) -> System.out.println(key + ":" + value));

If someone is still having issue then Build->Clean Project then Build->Rebuild project finally Sync project with Gradle file.

$id = 101;

$sql = 'SELECT * FROM ur_tbl t WHERE t.email_id = '. $id;
$email = Yii::app()->db->createCommand($sql)->queryAll();

var_dump($email);

this can also be tried...

SELECT l.ip, tbl2.ip as ip2, tbl2.hostname
FROM   login_log l 
LEFT   JOIN (SELECT ip_location.ip, ip_location.hostname
             FROM ip_location
             WHERE ip_location.ip is null)tbl2

Didn't see an example of both in one query. So this example might help.

  /**
INTERNATIONAL_ORDERS - table of orders by company by location by day
companyId, country, city, total, date
**/

SELECT country, city, sum(total) totalCityOrders 
FROM INTERNATIONAL_ORDERS with (nolock)
WHERE companyId = 884501253109
GROUP BY country, city
HAVING country = 'MX'
ORDER BY sum(total) DESC

This filters the table first by the companyId, then groups it (by country and city) and additionally filters it down to just city aggregations of Mexico. The companyId was not needed in the aggregation but we were able to use WHERE to filter out just the rows we wanted before using GROUP BY.

You can use df.index to access the index object and then get the values in a list using df.index.tolist(). Similarly, you can use df['col'].tolist() for Series.

With **Java 8* there is an alternative that use streams and lambdas:

public static void recursiveFind(Path path, Consumer<Path> c) {
  try (DirectoryStream<Path> newDirectoryStream = Files.newDirectoryStream(path)) {
    StreamSupport.stream(newDirectoryStream.spliterator(), false)
                 .peek(p -> {
                   c.accept(p);
                   if (p.toFile()
                        .isDirectory()) {
                     recursiveFind(p, c);
                   }
                 })
                 .collect(Collectors.toList());
  } catch (IOException e) {
    e.printStackTrace();
  }
}

So this will print all the files recursively:

recursiveFind(Paths.get("."), System.out::println);

And this will search for a file:

recursiveFind(Paths.get("."), p -> { 
  if (p.toFile().getName().toString().equals("src")) {
    System.out.println(p);
  }
});

a.btn {
  text-decoration: none;
}

More information will be useful.

When I was faced with the same error message all I had to do was to correctly configure the credentials page of the DataSource(I am using Report Builder 3). if you chose the default, the report would work fine in Report Builder but would fail on the Report Server.

You may review more details of this fix here: https://hodentekmsss.blogspot.com/2017/05/fix-for-rserroropeningconnection-in.html

I was dealing with this issue after upgrading from Visual Studio 2013 to Visual Studio 2015 After trying most of the advice found in this and other similar SO posts, I finally found the problem. The first part of the fix was to update all of my NuGet stuff to the latest version (you might need to do this in VS13 if you are experiencing the Nuget bug) after, I had to, as you may need to, fix the versions listed in the Views Web.config. This includes:

1. Fix MVC versions and its child libraries to the new version (expand the References then right click onSytem.Web.MVC then Properties to get your version)
2. Fix the Razor version.

Mine looked like this:

Here is what fixed for me:

1) Make sure you are running Visual Studio as Administrator

2) Install and run winhttpcertcfg.exe to grant access

https://msdn.microsoft.com/en-us/library/windows/desktop/aa384088(v=vs.85).aspx

The command is similar to below: (enter your certificate subject and service name)

winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "NetworkService"
winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "LOCAL SERVICE"
winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "My Apps Service Account"

This is a guess at best, but perhaps your development team is building and deploying the application in debug mode, in stead of release mode. This will cause the occurrence of .pdb files. The implication of this is that your application will take up additional resources to collect system state and debugging information during the execution of your system, causing more processor utilization.

So, it would be simple enough to ensure that they are building and deploying in release mode.

DO it like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$yourPHPVAR%'");

Do not forget the % at the end

Query string parameters can be accepted simply by using an argument on the action - i.e.

public ActionResult Foo(string someValue, int someOtherValue) {...}

which will accept a query like .../someroute?someValue=abc&someOtherValue=123

Other than that, you can look at the request directly for more control.

jackson-annotations provides @JsonFormat which can handle a lot of customizations without the need to write the custom serializer.

For example, requesting a STRING shape for a field with numeric type will output the numeric value as string

public class Person {
    public String name;
    public int age;
    @JsonFormat(shape = JsonFormat.Shape.STRING)
    public int favoriteNumber;
}

will result in the desired output

{"name":"Joe","age":25,"favoriteNumber":"123"}

The absolute divs are taken out of the flow of the document so the containing div does not have any content except for the padding. Give #box a height to fill it out.

#box {
    background-color: #000;
    position: relative;
    padding: 10px;
    width: 220px;
    height:30px;
}

I see lots of confusion in the comments. Null, IsNull() and vbNull are mainly used for database handling and normally not used in VBScript. If it is not explicitly stated in the documentation of the calling object/data, do not use it.

To test if a variable is uninitialized, use IsEmpty(). To test if a variable is uninitialized or contains "", test on "" or Empty. To test if a variable is an object, use IsObject and to see if this object has no reference test on Is Nothing.

In your case, you first want to test if the variable is an object, and then see if that variable is Nothing, because if it isn't an object, you get the "Object Required" error when you test on Nothing.

snippet to mix and match in your code:

If IsObject(provider) Then
    If Not provider Is Nothing Then
        ' Code to handle a NOT empty object / valid reference
    Else
        ' Code to handle an empty object / null reference
    End If
Else
    If IsEmpty(provider) Then
        ' Code to handle a not initialized variable or a variable explicitly set to empty
    ElseIf provider = "" Then
        ' Code to handle an empty variable (but initialized and set to "")
    Else
        ' Code to handle handle a filled variable
    End If
End If

In Simpler words, Pig is a high-level platform for creating MapReduce programs used with Hadoop, using pig scripts we will process the large amount of data into desired format.

Once the processed data obtained, this processed data is kept in HDFS for later processing to obtain the desired results.

On top of the stored processed data we will apply HIVE SQL commands to get the desired results, internally this hive sql commands runs MAP Reduce programs.

Parse it (i.e. with Integer#parseInt ) and simply catch the exception. =)

To clarify: The parseInt function checks if it can parse the number in any case (obviously) and if you want to parse it anyway, you are not going to take any performance hit by actually doing the parsing.

If you would not want to parse it (or parse it very, very rarely) you might wish to do it differently of course.

import sys
filename = sys.argv[1]
source = open(filename, 'r').read() + '\n'
compile(source, filename, 'exec')

Save this as checker.py and run python checker.py yourpyfile.py.

Valid hex colors can contain 0 to 9 and A to F so if we create a string with those characters and then shuffle it, we can grab the first 6 characters to create a random hex color code. An example is below!

code

echo '#' . substr(str_shuffle('ABCDEF0123456789'), 0, 6);

I tested this in a while loop and generated 10,000 unique colors.

code I used to generate 10,000 unique colors:

$colors = array();
while (true) {
   $color          = substr(str_shuffle('ABCDEF0123456789'), 0, 6);
   $colors[$color] = '#' . $color;
   if ( count($colors) == 10000 ) {
      echo implode(PHP_EOL, $colors);
      break;
   }
}

Which gave me these random colors as the result.

outis pointed out that my first example couldn't generate hexadecimals such as '4488CC' so I created a function which would be able to generate hexadecimals like that.

code

function randomHex() {
   $chars = 'ABCDEF0123456789';
   $color = '#';
   for ( $i = 0; $i < 6; $i++ ) {
      $color .= $chars[rand(0, strlen($chars) - 1)];
   }
   return $color;
}

echo randomHex();

The second example would be better to use because it can return a lot more different results than the first example, but if you aren't going to generate a lot of color codes then the first example would work just fine.

  SELECT t1.a, t2.b
  FROM t1
  JOIN t2 ON t1.a LIKE '%'+t2.b +'%'

because the last answer not work

What I learn about promises is to use it only as return values avoid referencing them if possible. async/await syntax is particularly practical for that. Today all latest browsers and node support it: https://caniuse.com/#feat=async-functions , is a simple behavior and the code is like reading synchronous code, forget about callbacks...

In cases I do need to reference a promises is when creation and resolution happen at independent/not-related places. So instead an artificial association and probably an event listener just to resolve the "distant" promise, I prefer to expose the promise as a Deferred, which the following code implements it in valid es5

/**
 * Promise like object that allows to resolve it promise from outside code. Example:
 *
```
class Api {
  fooReady = new Deferred<Data>()
  private knower() {
    inOtherMoment(data=>{
      this.fooReady.resolve(data)
    })
  }
}
```
 */
var Deferred = /** @class */ (function () {
  function Deferred(callback) {
    var instance = this;
    this.resolve = null;
    this.reject = null;
    this.status = 'pending';
    this.promise = new Promise(function (resolve, reject) {
      instance.resolve = function () { this.status = 'resolved'; resolve.apply(this, arguments); };
      instance.reject = function () { this.status = 'rejected'; reject.apply(this, arguments); };
    });
    if (typeof callback === 'function') {
      callback.call(this, this.resolve, this.reject);
    }
  }
  Deferred.prototype.then = function (resolve) {
    return this.promise.then(resolve);
  };
  Deferred.prototype.catch = function (r) {
    return this.promise.catch(r);
  };
  return Deferred;
}());

For more complex cases I often use these guy small promise utilities without dependencies tested and typed. p-map has been useful several times. I think he covered most use cases:

In case you want to handle intent on opened activity, you can use PendintIntent (Complete steps below):

public class SMSReciver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        final Bundle bundle = intent.getExtras();
        try {
            if (bundle != null) {
                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                for (int i = 0; i < pdusObj.length; i++) {
                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                    try {
                        if (senderNum.contains("MOB_NUMBER")) {
                            Toast.makeText(context,"",Toast.LENGTH_SHORT).show();

                            Intent intentCall = new Intent(context, MainActivity.class);
                            intentCall.putExtra("message", currentMessage.getMessageBody());

                            PendingIntent pendingIntent= PendingIntent.getActivity(context, 0, intentCall, PendingIntent.FLAG_UPDATE_CURRENT);
                            pendingIntent.send();
                        }
                    } catch (Exception e) {
                    }
                }
            }
        } catch (Exception e) {
        }
    }
} 

manifest:

<activity android:name=".MainActivity"
            android:launchMode="singleTask"/>
<receiver android:name=".SMSReciver">
            <intent-filter android:priority="1000">
                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
            </intent-filter>
        </receiver>

onNewIntent:

 @Override
         protected void onNewIntent(Intent intent) {
                super.onNewIntent(intent);
                Toast.makeText(this, "onNewIntent", Toast.LENGTH_SHORT).show();

                onSMSReceived(intent.getStringExtra("message"));

            }

permissions:

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />

This does't work in case of the JObject this works for the simple json format data. I have tried my data of the below json format data to deserialize in the type but didn't get the response.

For this Json

{
  "Customer": {
    "id": "Shell",
    "Installations": [
      {
        "id": "Shell.Bangalore",
        "Stations": [
          {
            "id": "Shell.Bangalore.BTM",
            "Pumps": [
              {
                "id": "Shell.Bangalore.BTM.pump1"
              },
              {
                "id": "Shell.Bangalore.BTM.pump2"
              },
              {
                "id": "Shell.Bangalore.BTM.pump3"
              }
            ]
          },

            "Pumps": [
              {
                "id": "Shell.Bangalore.Madiwala.pump4"
              },
              {
                "id": "Shell.Bangalore.Madiwala.pump5"
              }

I think the best way to use react-router-dom Link in a MenuItem (and other MaterialUI component such as buttons) is to pass the Link in the "component" prop

<Menu>
   <MenuItem component={Link} to={'/first'}>Team 1</MenuItem>
   <MenuItem component={Link} to={'/second'}>Team 2</MenuItem>
</Menu>

you need to pass the route path in the 'to' prop of the "MenuItem" (which will be passed down to the Link component). In this way you don't need to add any style as it will use the MenuItem style

The windows equivalent to the diff command is the fc (File Comapre) command.

Here are the basic steps to do so:
1. Keep the two files in a folder (Example file1.html and file2.html)
2. Launch command prompt
3. Type fc file1Location file2Location

Have found a detailed tutorial on the same:

I'm not aware of standard practices for package organization. I generally create packages that cover some reasonably broad spectrum, but I can differentiate within a project. For example, a personal project I'm currently working on has a package devoted to my customized UI controls (full of classes subclassing swing classes). I've got a package devoted to my database management stuff, I've got a package for a set of listeners/events that I've created, and so on.

On the other hand I've had a coworker create a new package for almost everything he did. Each different MVC he wanted got its own package, and it seemed a MVC set was the only grouping of classes allowed to be in the same package. I recall at one point he had 5 different packages that each had a single class in them. I think his method is a little bit on the extreme (and the team forced him to reduce his package count when we simply couldn't handle it), but for a nontrivial application, so would putting everything in the same package. It's a balance point you and your teammates have to find for yourself.

One thing you can do is try to step back and think: if you were a new member introduced to the project, or your project was released as open source or an API, how easy/difficult would it be to find what you want? Because for me, that's what I really want out of packages: organization. Similar to how I store files in folder on my computer, I expect to be able to find them again without having to search my entire drive. I expect to be able to find the class I want without having to search the list of all classes in the package.

you can use a static array in your method, to avoid lose of your array when your function ends :

char * createStr() 
{
    char char1= 'm';
    char char2= 'y';

    static char str[3];  
    str[0] = char1;
    str[1] = char2;
    str[2] = '\0';

    return str;
}

Edit : As Toby Speight mentioned this approach is not thread safe, and also recalling the function leads to data overwrite that is unwanted in some applications. So you have to save the data in a buffer as soon as you return back from the function. (However because it is not thread safe method, concurrent calls could still make problem in some cases, and to prevent this you have to use lock. capture it when entering the function and release it after copy is done, i prefer not to use this approach because its messy and error prone.)

To avoid all the Oracle mess of not knowing where it is looking for the TNSNAMES.ORA (I have the added confusion of multiple Oracle versions and 32/64 bit), you can copy the setting from your existing TNSNAMES.ORA to your own config file and use that for your connection.
Say you're happy with the 'DSDSDS' reference in TNSNAMES.ORA which maps to something like:

DSDSDS=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(Host=DSDSDSHost)(Port=4521)))(CONNECT_DATA=(SERVICE_NAME=DSDSDSService)))

For SQL Server 2005 upwards:

SELECT [name] AS [TableName], [create_date] AS [CreatedDate] FROM sys.tables

For SQL Server 2000 upwards:

SELECT so.[name] AS [TableName], so.[crdate] AS [CreatedDate]
FROM INFORMATION_SCHEMA.TABLES AS it, sysobjects AS so 
WHERE it.[TABLE_NAME] = so.[name]

You can also import only ZipFile:

from zipfile import ZipFile
zf = ZipFile('path_to_file/file.zip', 'r')
zf.extractall('path_to_extract_folder')
zf.close()

Works in Python 2 and Python 3.

f = open(fname,'r')
lines = f.readlines()[1:]
f.close()

You can do like below without TryParse or inbuilt functions:

static int convertToInt(string a)
{
    int x = 0;
    for (int i = 0; i < a.Length; i++)
    {
        int temp = a[i] - '0';
        if (temp != 0)
        {
            x += temp * (int)Math.Pow(10, (a.Length - (i+1)));
        }
    }
    return x;
}

Add your php folder path to the System PATH and everything should work fine. It will also fix some other extensions that are broken.

The suggestions to use cookies aside, the only comprehensive set of identifying attributes available to interrogate are contained in the HTTP request header. So it is possible to use some subset of these to create a pseudo-unique identifier for a user agent (i.e., browser). Further, most of this information is possibly already being logged in the so-called "access log" of your web server software by default and, if not, can be easily configured to do so. Then, a utlity could be developed that simply scans the content of this log, creating fingerprints of each request comprised of, say, the IP address and User Agent string, etc. The more data available, even including the contents of specific cookies, adds to the quality of the uniqueness of this fingerprint. Though, as many others have stated already, the HTTP protocol doesn't make this 100% foolproof - at best it can only be a fairly good indicator.

A sha256 is 256 bits long -- as its name indicates.

Since sha256 returns a hexadecimal representation, 4 bits are enough to encode each character (instead of 8, like for ASCII), so 256 bits would represent 64 hex characters, therefore you need a varchar(64), or even a char(64), as the length is always the same, not varying at all.

And the demo :

$hash = hash('sha256', 'hello, world!');
var_dump($hash);

Will give you :

$ php temp.php
string(64) "68e656b251e67e8358bef8483ab0d51c6619f3e7a1a9f0e75838d41ff368f728"

i.e. a string with 64 characters.

I would set the maximum size, minimum size and remove the gripper icon of the window.

Set properties (MaximumSize, MinimumSize, and SizeGripStyle):

this.MaximumSize = new System.Drawing.Size(500, 550);
this.MinimumSize = new System.Drawing.Size(500, 550);
this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;

1. The height of a node in a tree is the length of the longest path from that node downward to a leaf, counting both the start and end vertices of the path.
2. A node in a tree is height-balanced if the heights of its subtrees differ by no more than 1.
3. A tree is height-balanced if all of its nodes are height-balanced.
