Posting answer to my own question as I found it here and was hidden in bottom somewhere -

https://social.msdn.microsoft.com/Forums/vstudio/en-US/64baed8c-b00c-40d5-b19a-99b26a11516e/visual-c-redistributable-for-visual-studio-2015-rc-fails-on-windows-server-2012?forum=vssetup

This is because the OS failed to install the required update Windows8.1-KB2999226-x64.msu.

However, you can install it by extracting that update to a folder (e.g. XXXX), and execute following cmdlet. You can find the Windows8.1-KB2999226-x64.msu at below.

C:\ProgramData\Package Cache\469A82B09E217DDCF849181A586DF1C97C0C5C85\packages\Patch\amd64\Windows8.1-KB2999226-x64.msu

copy this file to a folder you like, and

Create a folder XXXX in that and execute following commands from Admin command propmt

wusa.exe Windows8.1-KB2999226-x64.msu /extract:XXXX

DISM.exe /Online /Add-Package /PackagePath:XXXX\Windows8.1-KB2999226-x64.cab

vc_redist.x64.exe /repair

(last command need not be run. Just execute vc_redist.x64.exe once again)

this worked for me.

If you know your file will live where your classes are, that directory will be on your classpath. In that case, you can be sure that this solution will solve your problem:

URL path = ClassLoader.getSystemResource("myFile.txt");
if(path==null) {
     //The file was not found, insert error handling here
}
File f = new File(path.toURI());

reader = new BufferedReader(new FileReader(f));

Could you try this out?

=IIF((Fields!OpeningStock.Value=0) AND (Fields!GrossDispatched.Value=0) AND 
(Fields!TransferOutToMW.Value=0) AND (Fields!TransferOutToDW.Value=0) AND 
(Fields!TransferOutToOW.Value=0) AND (Fields!NetDispatched.Value=0) AND (Fields!QtySold.Value=0) 
AND (Fields!StockAdjustment.Value=0) AND (Fields!ClosingStock.Value=0),True,False)

Note: Setting Hidden to False will make the row visible

Filename:

__file__
# or
sys.argv[0]

Line:

inspect.currentframe().f_lineno

(not inspect.currentframe().f_back.f_lineno as mentioned above)

Interestingly, this solution can break, but a workaround: Looking for my database called KeyWorks.accdb which must exist:

Run this:

Dim strDataPath As String = GetSetting("KeyWorks", "dataPath", "01", "") 'get from registry

If Not strDataPath.Contains("KeyWorks.accdb") Then....etc.

If my database is named KeyWorksBB.accdb, the If statement will find this acceptable and exit the If statement because it did indeed find KeyWorks and accdb.

If I surround the If statement qualifier with single quotes like 'KeyWorks.accdb', it now looks for all the consecutive characters in order and would enter the If block because it did not match.

My experience with this was that when I had this in every execution it was fine using the provider as a string like this

Security.addProvider(new BounctCastleProvider());
new JcaPEMKeyConverter().setProvider("BC");

But when I optimized and put the following in the constructor:

   if(bounctCastleProvider == null) {
      bounctCastleProvider = new BouncyCastleProvider();
    }

    if(Security.getProvider(bouncyCastleProvider.getName()) == null) {
      Security.addProvider(bouncyCastleProvider);
    }

Then I had to use provider like this or I would get the above error:

new JcaPEMKeyConverter().setProvider(bouncyCastleProvider);

I am using bcpkix-jdk15on version 1.65

SELECT CONCAT(LOWER(LAST_NAME), UPPER(LAST_NAME)
       INITCAP(LAST_NAME), HIRE DATE AS ‘up_low_init_hdate’)
FROM EMPLOYEES
WHERE HIRE DATE = 1995

for my specific problem I had to replace

if let count = 1
    {
        // do something ...
    }

With

let count = 1
if(count > 0)
    {
        // do something ...
    }

And if you simply want to cut part of a file - say from line 26 to 142 - and input it to a newfile : cat file-to-cut.txt | sed -n '26,142p' >> new-file.txt

A simple ES6 way to get both the first key and remaining parts in a string would be:

 const [key, ...rest] = "good_luck_buddy".split('_')
 const value = rest.join('_')
 console.log(key, value) // good, luck_buddy

In my case i have just put the Class MyprojectApplication in a package(com.example.start) with the same level of model, controller,service packages.

I am a newbie to svn version control. However, for the case when people want to add files without ignoring the already set svn:ignore properties, I solved the issue as below

1. svn add --depth empty path/to/directory
2. Execute "svn propset svn:ignore -F ignoreList.txt --recursive" from the location where the ignoreList.txt resides. In my case this file was residing two directories above the "path/to/directory", which I wanted to add. Note that ignoreList.txt contains the file extensions I want svn to ignore, e.g. *.aux etc.
3. svn add --force path/to/directory/.

The above steps worked.

The PyXB package at http://pyxb.sourceforge.net/ generates validating bindings for Python from XML schema documents. It handles almost every schema construct and supports multiple namespaces.

CONVERT(varchar,GETDATE(),102)

This is not a code issue. It is your default IE settings

To change the "always open" setting:

1. In Windows Explorer, click on the "Tools" menu, choose "Folder options"
2. In the window that appears, click on the "File Types" tab, and scroll through the list until you find the file extension you want to change (they're in alphabetical order). For example, if Internet Explorer always tries to open .zip files, scroll through the list until you find the entry for "zip".
3. Click on the file type, then the "Advanced" button.
4. Check the "Confirm after download" box, then click OK > Close.

EDIT: If you ask me , instead of making any changes in the code i would add the following text "Internet Explorer users: To download file, "Rightclick" the link and hit "Save target as" to download the file."

EDIT 2: THIS solution will work perfectly for you. Its a solution i just copied from the other answer. Im not trying to pass it off as my own

Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"

However you must make sure that you specify the type of file(s) you allow. You have mentioned in your post that you want this for any type of file. This will be an issue.

For ex. If your site has images and if the end user clicks these images then they will be downloaded on his computer instead of opening in a new page. Got the point. So you need to specify the file extensions.

This is one way of installing pip on a Windows system.

1. Download the "get-pip" python script from here: https://bootstrap.pypa.io/get-pip.py

2. Save the file as getpip.py

3. Run it from cmd: python getpip.py install

git --branch <branchname> <url>

But bash completion don't get this key: --branch

You can use print-dict

from print_dict import pd

dict1 = {
    'key': 'value'
} 

pd(dict1)

Output:

{
    'key': 'value'
}

Output of this Python code:

{
    'one': 'value-one',
    'two': 'value-two',
    'three': 'value-three',
    'four': {
        '1': '1',
        '2': '2',
        '3': [1, 2, 3, 4, 5],
        '4': {
            'method': <function custom_method at 0x7ff6ecd03e18>,
            'tuple': (1, 2),
            'unicode': '?',
            'ten': 'value-ten',
            'eleven': 'value-eleven',
            '3': [1, 2, 3, 4]
        }
    },
    'object1': <__main__.Object1 object at 0x7ff6ecc588d0>,
    'object2': <Object2 info>,
    'class': <class '__main__.Object1'>
}

Install:

$ pip install print-dict

Disclosure: I'm the author of print-dict

In Centos 6.7, in my case the library file /usr/lib64/php/modules/sqlite3.so was missing.

yum install php-pdo 

vim /etc/php.d/sqlite3.ini
; Enable sqlite3 extension module
extension=sqlite3.so

sudo service httpd restart

Or about the best module I have found http://pypi.python.org/pypi/colorama

Often, in event handlers, such as onsubmit, returning false is a way to tell the event to not actually fire. So, say, in the onsubmit case, this would mean that the form is not submitted.

You can use:

input[type=text]
{
 /*Styles*/
}

Define your common style attributes inside this. and for extra style you can add a class then.

int num;
bool isNumeric = int.TryParse("123", out num);

This can be done in two steps:

• For each source directory you should create own module.
• In all modules you should specify the same build directory: ${build.directory}

If you work with started Jetty (jetty:run), then recompilation of any class in any module (with Maven, IDEA or Eclipse) will lead to Jetty's restart. The same behavior you'll get for modified resources.

It works because the stack has not been altered (yet) since a was put there. Call a few other functions (which are also calling other functions) before accessing a again and you will probably not be so lucky anymore... ;-)

I just had the same problem. The reason was because there was a subfolder that contained a ".git" folder. Removing it made git happy.

Using session, I successfully passed a parameter (name) from servlet #1 to servlet #2, using response.sendRedirect in servlet #1. Servlet #1 code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) {
    String name = request.getParameter("name");
    String password = request.getParameter("password");
    ...
    request.getSession().setAttribute("name", name);
    response.sendRedirect("/todo.do");

In Servlet #2, you don't need to get name back. It's already connected to the session. You could do String name = (String) request.getSession().getAttribute("name"); ---but you don't need this.

If Servlet #2 calls a JSP, you can show name this way on the JSP webpage:

<h1>Welcome ${name}</h1>

An alternative to @inspectorG4dget answer (best answer to date 29-03-2016). I tested with 3 files of 436MB.

@inspectorG4dget solution: 162 seconds

The following solution : 125 seconds

from subprocess import Popen
filenames = ['file1.txt', 'file2.txt', 'file3.txt']
fbatch = open('batch.bat','w')
str ="type "
for f in filenames:
    str+= f + " "
fbatch.write(str + " > file4results.txt")
fbatch.close()
p = Popen("batch.bat", cwd=r"Drive:\Path\to\folder")
stdout, stderr = p.communicate()

The idea is to create a batch file and execute it, taking advantage of "old good technology". Its semi-python but works faster. Works for windows.

You sure can. Create an HTML page with the form in it that will contain the necessary components from the login.aspx page (i.e. username, etc), and make sure they have the same IDs. For you action, make sure it's a post.

You might have to do some code on the login.aspx page in the Page_Load function to read the form (in the Request.Form object) and call the appropriate functions to log the user in, but other than that, you should have access to the form, and can do what you want with it.

Here you go:

<html>_x000D_
<head>_x000D_
  <title>Cols</title>_x000D_
  <style>_x000D_
    #left {_x000D_
      width: 200px;_x000D_
      float: left;_x000D_
    }_x000D_
    #right {_x000D_
      margin-left: 200px;_x000D_
      /* Change this to whatever the width of your left column is*/_x000D_
    }_x000D_
    .clear {_x000D_
      clear: both;_x000D_
    }_x000D_
  </style>_x000D_
</head>_x000D_
_x000D_
<body>_x000D_
  <div id="container">_x000D_
    <div id="left">_x000D_

The solution that I use to open Popover for components is reactstrap (React Bootstrap 4 components).

    class Settings extends Component {
        constructor(props) {
            super(props);

            this.state = {
              popoversOpen: [] // array open popovers
            }
        }

        // toggle my popovers
        togglePopoverHelp = (selected) => (e) => {
            const index = this.state.popoversOpen.indexOf(selected);
            if (index < 0) {
              this.state.popoversOpen.push(selected);
            } else {
              this.state.popoversOpen.splice(index, 1);
            }
            this.setState({ popoversOpen: [...this.state.popoversOpen] });
        }

        render() {
            <div id="settings">
                <button id="PopoverTimer" onClick={this.togglePopoverHelp(1)} className="btn btn-outline-danger" type="button">?</button>
                <Popover placement="left" isOpen={this.state.popoversOpen.includes(1)} target="PopoverTimer" toggle={this.togglePopoverHelp(1)}>
                  <PopoverHeader>Header popover</PopoverHeader>
                  <PopoverBody>Description popover</PopoverBody>
                </Popover>

                <button id="popoverRefresh" onClick={this.togglePopoverHelp(2)} className="btn btn-outline-danger" type="button">?</button>
                <Popover placement="left" isOpen={this.state.popoversOpen.includes(2)} target="popoverRefresh" toggle={this.togglePopoverHelp(2)}>

    }

I have same problem after upgrading to Gradle Wrapper 5.1.rec3. I am back to Gradle 4.6

Why not use a FileStream object?

public void SaveStreamToFile(string fileFullPath, Stream stream)
{
    if (stream.Length == 0) return;

    // Create a FileStream object to write a stream to a file
    using (FileStream fileStream = System.IO.File.Create(fileFullPath, (int)stream.Length))
    {
        // Fill the bytes[] array with the stream data
        byte[] bytesInStream = new byte[stream.Length];
        stream.Read(bytesInStream, 0, (int)bytesInStream.Length);

        // Use FileStream object to write to the specified file
        fileStream.Write(bytesInStream, 0, bytesInStream.Length);
     }
}

If it is a game(may be app also) and you have some static libraries like cocos2d or other third party library ... then you just have to select *ONLY THE* static library (NOT THE APP) and in its build settings under Deployment , set Skip Install flag to YES and Archive it dats it...!!

Pandas DataFrame columns are Pandas Series when you pull them out, which you can then call x.tolist() on to turn them into a Python list. Alternatively you cast it with list(x).

import pandas as pd

data_dict = {'one': pd.Series([1, 2, 3], index=['a', 'b', 'c']),
             'two': pd.Series([1, 2, 3, 4], index=['a', 'b', 'c', 'd'])}

df = pd.DataFrame(data_dict)

print(f"DataFrame:\n{df}\n")
print(f"column types:\n{df.dtypes}")

col_one_list = df['one'].tolist()

col_one_arr = df['one'].to_numpy()

print(f"\ncol_one_list:\n{col_one_list}\ntype:{type(col_one_list)}")
print(f"\ncol_one_arr:\n{col_one_arr}\ntype:{type(col_one_arr)}")

Output:

DataFrame:
   one  two
a  1.0    1
b  2.0    2
c  3.0    3
d  NaN    4

column types:
one    float64
two      int64
dtype: object

col_one_list:
[1.0, 2.0, 3.0, nan]
type:<class 'list'>

col_one_arr:
[ 1.  2.  3. nan]
type:<class 'numpy.ndarray'>

For example:

you can use:

to remove the NA in column a.

It is rule of thumb that the first layer in your network should be the same shape as your data. For example our data is 28x28 images, and 28 layers of 28 neurons would be infeasible, so it makes more sense to 'flatten' that 28,28 into a 784x1. Instead of wriitng all the code to handle that ourselves, we add the Flatten() layer at the begining, and when the arrays are loaded into the model later, they'll automatically be flattened for us.

This command:

git ls-tree --full-tree -r --name-only HEAD

lists all of the already committed files being tracked by your git repo.

Use a HTML parser like DOMDocument and then evaluate the value you're looking for with DOMXpath:

$html = '<img id="12" border="0" src="/images/image.jpg"
         alt="Image" width="100" height="100" />';

$doc = new DOMDocument();
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
$src = $xpath->evaluate("string(//img/@src)"); # "/images/image.jpg"

Or for those who really need to save space:

$xpath = new DOMXPath(@DOMDocument::loadHTML($html));
$src = $xpath->evaluate("string(//img/@src)");

And for the one-liners out there:

$src = (string) reset(simplexml_import_dom(DOMDocument::loadHTML($html))->xpath("//img/@src"));

You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.

When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.

Reference:
C++03 standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:

• To move the definition to the .h file
• Add explicit instantiations in the .cpp file.
• #include the .cpp file defining the template at the .cpp file using the template.

Each of them have their pros and cons,

Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.

Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.

While including cpp files is confusing at the same time shares the problems of both above approaches.

I find first method the easiest to follow and implement and hence advocte using it.

My below code solve this issue, but i suggest First of all you need to understand what causing this issue and try the solution which you can find by changing code

I can give another way to solve this issue but better solution is to check your coding structure and try to analyse what makes this happen,if you do not find any solution then you can go with this code below

try{
Start:
///Put your file access code here


}catch (Exception ex)
 {
//by anyway you need to handle this error with below code
   if (ex.Message.StartsWith("The process cannot access the file"))
    {
         //Wait for 5 seconds to free that file and then start execution again
         Thread.Sleep(5000);
         goto Start;
    }
 }

numpy has arrays that allow you to use other lists/arrays as indices:

import numpy
S=numpy.array(s)
S[a]=m

If you want to perform this inside your program then I would do something like:

#include <unistd.h>
int main()
{
  if(chdir("/c") < 0 )  
  {
     printf("Failed\n");
     return -1 ;
  }

  // rest of your program...

}

Try this:

$Object = 'FirstPart SecondPart' | ConvertFrom-String -PropertyNames Val1, Val2
$Object.Val1
$Object.Val2

Here is the solution for Rest API

class Program
{
    static void Main(string[] args)
    {
        BaseClient clientbase = new BaseClient("https://website.com/api/v2/", "username", "password");
        BaseResponse response = new BaseResponse();
        BaseResponse response = clientbase.GetCallV2Async("Candidate").Result;
    }


    public async Task<BaseResponse> GetCallAsync(string endpoint)
    {
        try
        {
            HttpResponseMessage response = await client.GetAsync(endpoint + "/").ConfigureAwait(false);
            if (response.IsSuccessStatusCode)
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            else
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            return baseresponse;
        }
        catch (Exception ex)
        {
            baseresponse.StatusCode = 0;
            baseresponse.ResponseMessage = (ex.Message ?? ex.InnerException.ToString());
        }
        return baseresponse;
    }
}


public class BaseResponse
{
    public int StatusCode { get; set; }
    public string ResponseMessage { get; set; }
}

public class BaseClient
{
    readonly HttpClient client;
    readonly BaseResponse baseresponse;

    public BaseClient(string baseAddress, string username, string password)
    {
        HttpClientHandler handler = new HttpClientHandler()
        {
            Proxy = new WebProxy("http://127.0.0.1:8888"),
            UseProxy = false,
        };

        client = new HttpClient(handler);
        client.BaseAddress = new Uri(baseAddress);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        var byteArray = Encoding.ASCII.GetBytes(username + ":" + password);

        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

        baseresponse = new BaseResponse();

    }
}

The only reliable way to open it is Window -> Show View -> Other -> Search "console". There was a handful suggestions in this post and none of them works! Apparently Eclipse likes to change their logic every other second.

Also, resetting the view is the most horrible suggestion, because that way you will lose everything you have ever done to change the layout, so it will probably not work for the most of the readers.

According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:

• Informing each search engine of the location through their provided interface
• Adding url to the robots.txt file
• Submiting url to search engines through http

So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.

A socket allows to the communication between two applications in a single machine or two machine. actually it is like door. if the door opens there can be a connection between the process or application that are inside the door and outside the door.

There are 4 types of sockets:

• stream sockets
• datagram sockets
• raw sockets
• sequential packet sockets.

Sockets are mostly used in client-server applications. The port identifies different end points on a network address. It contains a numerical value. As overall a socket is a combination of a port and a network address.

Unfortunately, all the previous answers are missing some details. The correct solution is a little bit cumbersome, but this is the only way to do it properly. And it scales easily, handles more complex dependencies as well.

Here's how you can do this, exactly retaining all the details, and usability:

• the solution is exactly the same as originally intended
• inline functions still inline
• users of A and B can include A.h and B.h in any order

Create two files, A_def.h, B_def.h. These will contain only A's and B's definition:

// A_def.h
#ifndef A_DEF_H
#define A_DEF_H

class B;
class A
{
    int _val;
    B *_b;

public:
    A(int val);
    void SetB(B *b);
    void Print();
};
#endif

// B_def.h
#ifndef B_DEF_H
#define B_DEF_H

class A;
class B
{
    double _val;
    A* _a;

public:
    B(double val);
    void SetA(A *a);
    void Print();
};
#endif

And then, A.h and B.h will contain this:

// A.h
#ifndef A_H
#define A_H

#include "A_def.h"
#include "B_def.h"

inline A::A(int val) :_val(val)
{
}

inline void A::SetB(B *b)
{
    _b = b;
    _b->Print();
}

inline void A::Print()
{
    cout<<"Type:A val="<<_val<<endl;
}

#endif

// B.h
#ifndef B_H
#define B_H

#include "A_def.h"
#include "B_def.h"

inline B::B(double val) :_val(val)
{
}

inline void B::SetA(A *a)
{
    _a = a;
    _a->Print();
}

inline void B::Print()
{
    cout<<"Type:B val="<<_val<<endl;
}

#endif

Note that A_def.h and B_def.h are "private" headers, users of A and B should not use them. The public header is A.h and B.h.

Mono Develop is what you want, if you have used visual studio you should find it simple enough to get started.

If I recall correctly you should be able to install with sudo apt-get install monodevelop

If any one is facing the problem in windows machine then follow the steps.

1. Add the path of mongodb in the environmental variable.
2. Create a directory C:\Data\db.
3. Open a terminal(cmd) and write mongod. (it will initiate the server).
4. Open another terminal and write your own code.

Re-posted as an answer: Found an alternative (Tested in Win8):

cmdkey /generic:"<server>" /user:"<user>" /pass:"<pass>"

Run that and if you run:

mstsc /v:<server>

You should not get an authentication prompt.

Before we try to solve the invalid character problem, the lack of curly braces around the if and else if statements is wreaking havoc on your program's logic. Change it to this:

if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}
else 
     System.out.println("Invalid user input.");

Much clearer! It's now actually a piece of cake to catch the bad characters. You need to move the else statement to somewhere that will catch the errors before you attempt to process anything else. So change everything to:

if( /* insert your check for bad characters here */ ) { 
     System.out.println("Invalid user input.");
}
else if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but I'm practically certain that System V grep did, so in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

Default parameter values must appear on the declaration, since that is the only thing that the caller sees.

EDIT: As others point out, you can have the argument on the definition, but I would advise writing all code as if that wasn't true.

You're using junit.framework.Assert instead of org.junit.Assert.

As others pointed out, the most straightforward way to deploy a WAR is to copy it to the webapps of the Tomcat install. Another option would be to use the manager application if it is installed (this is not always the case), if it's properly configured (i.e. if you have the credentials of a user assigned to the appropriate group) and if it you can access it over an insecure network like Internet (but this is very unlikely and you didn't mention any VPN access). So this leaves you with the webappdirectory.

Now, if Tomcat is installed and running on bilgin.ath.cx (as this is the machine where you uploaded the files), I noticed that Apache is listening to port 80 on that machien so I would bet that Tomcat is not directly exposed and that requests have to go through Apache. In that case, I think that deploying a new webapp and making it visible to the Internet will involve the edit of Apache configuration files (mod_jk?, mod_proxy?). You should either give us more details or discuss this with your hosting provider.

Update: As expected, the bilgin.ath.cx is using Apache Tomcat + Apache HTTPD + mod_jk. The configuration usually involves two files: the worker.properties file to configure the workers and the httpd.conf for Apache. Now, without seeing the current configuration, it's not easy to give a definitive answer but, basically, you may have to add a JkMount directive in Apache httpd.conf for your new webapp¹. Refer to the mod_jk documentation, it has a simple configuration example. Note that modifying httpd.conf will require access to (obviously) and proper rights and that you'll have to restart Apache after the modifications.

_{¹ I don't think you'll need to define a new worker if you are deploying to an already used Tomcat instance, especially if this sounds like Chinese for you :)}

If you need to put it in the tag. Not the finest solution, but it will work.

Make sure you put the onclick event in front of the href. Only worked for my this way.

<a onclick="return false;" href="//www.google.de">Google</a>

You need to have cl.exe (the Microsoft C Compiler) installed on your computer and in your PATH. PATH is an environment variable that tells Windows where to find executable files.

First, ensure the C++ build tools for Visual Studio are installed. You can download Build Tools for Visual Studio separately from the Visual Studio downloads page, then choose C++ build tools from the installer. If you already have Visual Studio, you can also install Desktop development with C++ from the Visual Studio Installer which you should have in Start Menu.

Then, instead of the normal Command Prompt or PowerShell, use one of the special command prompts in the Visual Studio folder in Start Menu. For 32-bit Python, you're probably looking for x86 Native Tools Command Prompt. This sets up PATH automatically, so that cl.exe can be found.

Here I am writing some sample code hoping this may be a rather tangible example to see the behaviors of the interfaces, abstract classes and ordinary classes on a very basic level. You can also find this code in github as a project if you want to use it as a demo: https://github.com/usavas/JavaAbstractAndInterfaceDemo

public interface ExampleInterface {

//    public void MethodBodyInInterfaceNotPossible(){
//    }
    void MethodInInterface();

}

public abstract class AbstractClass {
    public abstract void AbstractMethod();

    //    public abstract void AbstractMethodWithBodyNotPossible(){
    //
    //    };

    //Standard Method CAN be declared in AbstractClass
    public void StandardMethod(){
        System.out.println("Standard Method in AbstractClass (super) runs");
    }
}

public class ConcreteClass
    extends AbstractClass
    implements ExampleInterface{

    //Abstract Method HAS TO be IMPLEMENTED in child class. Implemented by ConcreteClass
    @Override
    public void AbstractMethod() {
        System.out.println("AbstractMethod overridden runs");
    }

    //Standard Method CAN be OVERRIDDEN.
    @Override
    public void StandardMethod() {
        super.StandardMethod();
        System.out.println("StandardMethod overridden in ConcreteClass runs");
    }

    public void ConcreteMethod(){
        System.out.println("Concrete method runs");
    }

    //A method in interface HAS TO be IMPLEMENTED in implementer class.
    @Override
    public void MethodInInterface() {
        System.out.println("MethodInInterface Implemented by ConcreteClass runs");

    //    Cannot declare abstract method in a concrete class
    //    public abstract void AbstractMethodDeclarationInConcreteClassNotPossible(){
    //
    //    }
    }
}

Depending on the need for performance and amount of elements to be added, this might be an ok solution. If the amount of elements are high, the Arraylists reallocation of memory might be a bit slower than StringBuilder.

var input = document.getElementById ("IdofInput");
input.placeholder = "No need to fill this field";

install boostrap using npm

npm install boostrap@next --save

then check your node_modules folder for boostrap.css file(within dist) normally the path is

"../node_modules/bootstrap/dist/css/bootstrap.css",

add this path | import boostrap within style.css or style.scss

@import "../node_modules/bootstrap/dist/css/bootstrap.css";  //bootstrap
@import "~@angular/material/prebuilt-themes/indigo-pink.css // angular material theme

that's it.

Clone target repository same way like you cloning any other project:

git clone [email protected]:myuser/foo.git

Then install it in develop mode:

cd foo
pip install -e .

You can change anything you wan't and every code using foo package will use modified code.

There 2 benefits ot this solution:

1. You can install package in your home projects directory.
2. Package includes .git dir, so it's regular Git repository. You can push to your fork right away.

if (intent.resolveActivity(getPackageManager()) != null) 
{
   startActivity(intent);
}

You could try:

tr:hover {
    background-color: #000;
}

tr:hover td {
    background-color: transparent; /* or #000 */
}

You can also use PreviewKeyDown in WPF:

<TextBox PreviewKeyDown="EnterClicked" />

or in C#:

myTextBox.PreviewKeyDown += EnterClicked;

And then in the attached class:

void EnterClicked(object sender, KeyEventArgs e) {
    if(e.Key == Key.Return) {
        DoSomething();
        e.Handled = true;
    }
}

Spread Syntax (ES6)

To whoever needs it...

To complete @Koen answer in this thread, in case you want to remove dynamic variable using the spread syntax, you can do it like so:

const key = 'a';_x000D_
        _x000D_
const { [key]: foo, ...rest } = { a: 1, b: 2, c: 3 };_x000D_
_x000D_
console.log(foo);  // 1_x000D_
console.log(rest); // { b: 2, c: 3 }

* foo will be a new variable with the value of a (which is 1).

EXTENDED ANSWER
There are few common ways to remove a property from an object.
Each one has it's own pros and cons (check this performance comparison):

Delete Operator
Readable and short, however, it might not be the best choice if you are operating on a large number of objects as its performance is not optimized.

delete obj[key];

Reassignment
More than 2X faster than delete, however the property is not deleted and can be iterated.

obj[key] = null;
obj[key] = false;
obj[key] = undefined;

Spread Operator
This ES6 operator allows us to return a brand new object, excluding any properties, without mutating the existing object. The downside is that it has the worse performance out of the above and not suggested to be used when you need to remove many properties at a time.

{ [key]: val, ...rest } = obj;

Maximum value: 2147483647

setcookie("CookieName", "CookieValue", 2147483647);

To avoid integer overflow the timestamp should be set to:

2^31 - 1 = 2147483647 = 2038-01-19 04:14:07

Setting a higher value might cause problems with older browsers.

Also see the RFC about cookies:

Max-Age=value
  OPTIONAL.  The value of the Max-Age attribute is delta-seconds,
  the lifetime of the cookie in seconds, a decimal non-negative
  integer.  To handle cached cookies correctly, a client SHOULD
  calculate the age of the cookie according to the age calculation
  rules in the HTTP/1.1 specification [RFC2616].  When the age is
  greater than delta-seconds seconds, the client SHOULD discard the
  cookie.  A value of zero means the cookie SHOULD be discarded
  immediately.

and RFC 2616, 14.6 Age:

If a cache receives a value larger than the largest positive integer it can represent, or if any of its age calculations overflows, it MUST transmit an Age header with a value of 2147483648 (2^31).

http://www.faqs.org/rfcs/rfc2616.html

Here's what I've done:

.resize {
    width: 400px;
    height: auto;
}

.resize {
    width: 300px;
    height: auto;
}

<img class="resize" src="example.jpg"/>

This will keep the image aspect ratio the same.

For your information you could use grid but with side effects :)

.parent {
  display: grid
}

yum list installed | grep mysql

Then if it's not installed you can do (as root)

yum install mysql -y

I already found the solution to this problem which I forgot to post here.

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Test.class })
public class SampleTest {

@Mock
Person person;

@Test
public void testPrintName() throws Exception {
    PowerMockito.whenNew(Person.class).withNoArguments().thenReturn(person);
    Test test= new Test();
    test.testMethod();
    }
}

Key points to this solution are:

1. Running my test cases with PowerMockRunner: @RunWith(PowerMockRunner.class)

2. Instruct Powermock to prepare Test.class for manipulation of private fields: @PrepareForTest({ Test.class })

3. And finally mock the constructor for Person class:

   PowerMockito.mockStatic(Person.class); PowerMockito.whenNew(Person.class).withNoArguments().thenReturn(person);

I modified @kolbyjack code to make it work for

http://website1/service
http://website1/service/

with parameters

location ~ ^/service/?(.*) {
    return 301 http://service_url/$1$is_args$args;
}

It's important to note, that NULL doesn't equal NULL.

NULL is not a value, and therefore cannot be compared to another value.

where x is null checks whether x is a null value.

where x = null is checking whether x equals NULL, which will never be true

For those who are trying to install php-curl on PHP 7, it will result in an error. Actually if you are installing php-curl in PHP 7, the package name should be;

sudo apt-get install php-curl

Not php5-curl or php7-curl, just php-curl.

Use ALTER:

ALTER TABLE `tbl_Country` DROP COLUMN `column_name`;

This is not an answer, but a comment, but I could not write a comment with a formatted code, so here is the comment.

Lets say there is

public static void main(String[] args) {
  try {
    // do nothing or throw a RuntimeException
    throw new RuntimeException("test");
  } catch (Exception e) {
    System.out.println(e.getMessage());
    throw e;
  }
}

The output is

test
Exception in thread "main" java.lang.RuntimeException: test
    at MyClass.main(MyClass.java:10)

That method does not declare any "throws" Exceptions, but throws them! The trick is that the thrown exceptions are RuntimeExceptions (unchecked) that are not needed to be declared on the method. It is a bit misleading for the reader of the method, since all she sees is a "throw e;" statement but no declaration of the throws exception

Now, if we have

public static void main(String[] args) throws Exception {
  try {
    throw new Exception("test");
  } catch (Exception e) {
    System.out.println(e.getMessage());
    throw e;
  }
}

We MUST declare the "throws" exceptions in the method otherwise we get a compiler error.

No, there is no better way; yours is canonical.

It is important to note that object files are assembled to binary code in a format that is relocatable. This is a form which allows the assembled code to be loaded anywhere into memory for use with other programs by a linker.

Instructions that refer to labels will not yet have an address assigned for these labels in the .o file.

These labels will be written as '0' and the assembler creates a relocation record for these unknown addresses. When the file is linked and output to an executable the unknown addresses are resolved and the program can be executed.

You can use the nm tool on an object file to list the symbols defined in a .o file.

Use this to find the scroll direction. This is only to find the direction of the Vertical Scroll. Supports all cross browsers.

var scrollableElement = document.body; //document.getElementById('scrollableElement');

scrollableElement.addEventListener('wheel', checkScrollDirection);

function checkScrollDirection(event) {
  if (checkScrollDirectionIsUp(event)) {
    console.log('UP');
  } else {
    console.log('Down');
  }
}

function checkScrollDirectionIsUp(event) {
  if (event.wheelDelta) {
    return event.wheelDelta > 0;
  }
  return event.deltaY < 0;
}

Example

You need to use the URL for the link, such as this:

NSURL *path = [[NSBundle mainBundle] URLForResource:@"imagename" withExtension:@"jpg"];

It will give you a proper URL ref.

Aggregate functions may help you out here. Aggregate functions ignore NULLs (at least that's true on SQL Server, Oracle, and Jet/Access), so you could use a query like this (tested on SQL Server Express 2008 R2):

SELECT
    FK,
    MAX(Field1) AS Field1,
    MAX(Field2) AS Field2
FROM
    table1
GROUP BY
    FK;

I used MAX, but any aggregate which picks one value from among the GROUP BY rows should work.

Test data:

CREATE TABLE table1 (FK int, Field1 varchar(10), Field2 varchar(10));

INSERT INTO table1 VALUES (3, 'ABC', NULL);
INSERT INTO table1 VALUES (3, NULL, 'DEF');
INSERT INTO table1 VALUES (4, 'GHI', NULL);
INSERT INTO table1 VALUES (4, 'JKL', 'MNO');
INSERT INTO table1 VALUES (4, NULL, 'PQR');

Results:

FK  Field1  Field2
--  ------  ------
3   ABC     DEF
4   JKL     PQR

I solved the problem easily (pragmatic) by adding the option to the constructor. Thus, i use that only when needed.

public class Something : DbContext
{
    public Something(bool MultipleActiveResultSets = false)
    {
        this.Database
            .Connection
            .ConnectionString = Shared.ConnectionString /* your connection string */
                              + (MultipleActiveResultSets ? ";MultipleActiveResultSets=true;" : "");
    }
...

NOTE: Not sure it works with the latest version of Angular.

ORIGINAL:

It's also possible to override the OPTIONS request (was only tested in Chrome):

app.config(['$httpProvider', function ($httpProvider) {
  //Reset headers to avoid OPTIONS request (aka preflight)
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
}]);

Standard C doesn't define binary constants. There's a GNU (I believe) extension though (among popular compilers, clang adapts it as well): the 0b prefix:

int foo = 0b1010;

If you want to stick with standard C, then there's an option: you can combine a macro and a function to create an almost readable "binary constant" feature:

#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
        unsigned long long i = 0;
        while (*s) {
                i <<= 1;
                i += *s++ - '0';
        }
        return i;
}

And then you can use it like this:

int foo = B(1010);

If you turn on heavy compiler optimizations, the compiler will most likely eliminate the function call completely (constant folding) or will at least inline it, so this won't even be a performance issue.

Proof:

The following code:

#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
#include <string.h>


#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
    unsigned long long i = 0;
    while (*s) {
        i <<= 1;
        i += *s++ - '0';
    }
    return i;
}

int main()
{
    int foo = B(001100101);

    printf("%d\n", foo);

    return 0;
}

has been compiled using clang -o baz.S baz.c -Wall -O3 -S, and it produced the following assembly:

    .section    __TEXT,__text,regular,pure_instructions
    .globl  _main
    .align  4, 0x90
_main:                                  ## @main
    .cfi_startproc
## BB#0:
    pushq   %rbp
Ltmp2:
    .cfi_def_cfa_offset 16
Ltmp3:
    .cfi_offset %rbp, -16
    movq    %rsp, %rbp
Ltmp4:
    .cfi_def_cfa_register %rbp
    leaq    L_.str1(%rip), %rdi
    movl    $101, %esi               ## <= This line!
    xorb    %al, %al
    callq   _printf
    xorl    %eax, %eax
    popq    %rbp
    ret
    .cfi_endproc

    .section    __TEXT,__cstring,cstring_literals

    .asciz   "%d\n"


.subsections_via_symbols

So clang completely eliminated the call to the function, and replaced its return value with 101. Neat, huh?

Bit late but hopefully can still be useful to someone.

2 steps to adding items to a specific position in an ArrayList

1. add null items to a specific index in an ArrayList

2. Then set the positions as and when required.

       list = new ArrayList();//Initialise the ArrayList
   for (Integer i = 0; i < mItems.size(); i++) {
       list.add(i, null); //"Add" all positions to null
   }
      // "Set" Items
       list.set(position, SomeObject);
   

This way you don't have redundant items in the ArrayList i.e. if you were to add items such as,

list = new ArrayList(mItems.size());    
list.add(position, SomeObject);

This would not overwrite existing items in the position merely, shifting existing ones to the right by one - so you have an ArrayList with twice as many indicies.

Both of the previous 2 answers have at least O(n) time complexity and the string conversion has O(n) space complexity too. Here's a solution for constant time and space:

num // 10 ** (int(math.log(num, 10)) - 1)

Function:

import math

def first_n_digits(num, n):
    return num // 10 ** (int(math.log(num, 10)) - n + 1)

Output:

>>> first_n_digits(123456, 1)
1
>>> first_n_digits(123456, 2)
12
>>> first_n_digits(123456, 3)
123
>>> first_n_digits(123456, 4)
1234
>>> first_n_digits(123456, 5)
12345
>>> first_n_digits(123456, 6)
123456

You will need to add some checks if it's possible that your input number has less digits than you want.

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<a href="xxx.html" style="text-decoration:none;">goto this link</a>

Inline stylesheet:

<html>
<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

External stylesheet:

<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

stylesheet.css:

a {
      text-decoration:none;
   }

I found myself in the same situation and ended up adding these aliases to my .profile file:

alias c1="awk '{print \$1}'"
alias c2="awk '{print \$2}'"
alias c3="awk '{print \$3}'"
alias c4="awk '{print \$4}'"
alias c5="awk '{print \$5}'"
alias c6="awk '{print \$6}'"
alias c7="awk '{print \$7}'"
alias c8="awk '{print \$8}'"
alias c9="awk '{print \$9}'"

Which allows me to write things like this:

svn st | c2 | xargs rm

Make sure you properly escape the quotes.

  string line = "\"Text\",\"Text\",\"Text\",";

  string result = line.Replace("\",\"", ";");

You could try Davis.js, it gives you routing in your JavaScript using pushState when available and without JavaScript it allows your server side code to handle the requests.

Use Math.round(), possibly in conjunction with MidpointRounding.AwayFromZero

eg:

Math.Round(1.2) ==> 1
Math.Round(1.5) ==> 2
Math.Round(2.5) ==> 2
Math.Round(2.5, MidpointRounding.AwayFromZero) ==> 3

Yes, there is Oracle SQL Developer, which is maintained by Oracle.

Oracle SQL Developer is a free graphical tool for database development. With SQL Developer, you can browse database objects, run SQL statements and SQL scripts, and edit and debug PL/SQL statements. You can also run any number of provided reports, as well as create and save your own. SQL Developer enhances productivity and simplifies your database development tasks.

SQL Developer can connect to any Oracle Database version 10g and later and runs on Windows, Linux and Mac OSX.

For the carousel, I believe all images have to be exactly the same height and width.

Also, when you refer back to the scaffolding page from bootstrap, I'm pretty sure that span16 = 940px. With this in mind, I think we can assume that if you have a

<div class="row">
     <div class="span4"> 
        <!--left content div guessing around 235px in width -->
     </div>
     <div class="span8">
        <!--right content div guessing around 470px in width -->
     </div>
</div>

So yes, you have to be careful when setting the spans space within a row because if the image width is to large, it will send your div over into the next "row" and that is no fun :P

Try this:

$.grep(array, function(element) {

})

When less than 9 datasets:

colors = "bgrcmykw"
color_index = 0

for X,Y in data:
    scatter(X,Y, c=colors[color_index])
    color_index += 1

You can set its startup type to manual in services.msc. This way it will not start automatically unless required. Simply get the name of the service from services.msc as shown here:

You can create batch files to start and stop the service fairly easily as well. Now use this name in batch files.

Your start.bat:

net start "mysql"

And in your stop.bat:

net stop "mysql"

As mentioned in other answers, the Panel generates a <div> in HTML, while the PlaceHolder does not. But there are a lot more reasons why you could choose either one.

Why a PlaceHolder?

Since it generates no tag of it's own you can use it safely inside other element that cannot contain a <div>, for example:

<table>
    <tr>
        <td>Row 1</td>
    </tr>
    <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</table>

You can also use a PlaceHolder to control the Visibility of a group of Controls without wrapping it in a <div>

<asp:PlaceHolder ID="PlaceHolder1" runat="server" Visible="false">
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <br />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</asp:PlaceHolder>

Why a Panel

It generates it's own <div> and can also be used to wrap a group of Contols. But a Panel has a lot more properties that can be useful to format it's content:

<asp:Panel ID="Panel1" runat="server" Font-Bold="true"
    BackColor="Green" ForeColor="Red" Width="200"
    Height="200" BorderColor="Black" BorderStyle="Dotted">
    Red text on a green background with a black dotted border.
</asp:Panel>

But the most useful feature is the DefaultButton property. When the ID matches a Button in the Panel it will trigger a Form Post with Validation when enter is pressed inside a TextBox. Now a user can submit the Form without pressing the Button.

<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <br />
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
        ErrorMessage="Input is required" ValidationGroup="myValGroup"
        Display="Dynamic" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>
    <br />
    <asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="myValGroup" />
</asp:Panel>

Try the above snippet by pressing enter inside TextBox1

I just discovered this: https://greek0.net/boost-range/boost-adaptors-indexed.html

    for (const auto & element : str | boost::adaptors::indexed(0)) {
        std::cout << element.index()
                  << " : "
                  << element.value()
                  << std::endl;
    }

Here how I solved this issue without touching the build:

1- Closed the Virtual Device

2- Tested on Physical Device --(it works)

3- Created new Virtual Device with API 30 Android 10+

4- Try again on newly created Virtual Device, and all work like a charm.

This is the only code that worked for me:

for /f "tokens=4" %%G IN ("aaa bbb ccc ddd eee fff") DO echo %%G 

output:

ddd

A slightly more concise example that builds on top of the other answers here. I leveraged the code generation that is shipped with Visual Studio to remove most of the extra invocation code and replaced it with typed objects instead.

I understand the ZooKeeper in general but had problems with the terms "quorum" and "split brain" so maybe I can share my findings with you (I consider myself also a layman).

Let's say we have a ZooKeeper cluster of 5 servers. One of the servers will become the leader and the others will become followers.

• These 5 servers form a quorum. Quorum simply means "these servers can vote upon who should be the leader".

• So the voting is based on majority. Majority simply means "more than half" so more than half of the number of servers must agree for a specific server to become the leader.

• So there is this bad thing that may happen called "split brain". A split brain is simply this, as far as I understand: The cluster of 5 servers splits into two parts, or let's call it "server teams", with maybe one part of 2 and the other of 3 servers. This is really a bad situation as if both "server teams" must execute a specific order how would you decide wich team should be preferred? They might have received different information from the clients. So it is really important to know what "server team" is still relevant and which one can/should be ignored.

• Majority is also the reason you should use an odd number of servers. If you have 4 servers and a split brain where 2 servers seperate then both "server teams" could say "hey, we want to decide who is the leader!" but how should you decide which 2 servers you should choose? With 5 servers it's simple: The server team with 3 servers has the majority and is allowed to select the new leader.

• Even if you just have 3 servers and one of them fails the other 2 still form the majority and can agree that one of them will become the new leader.

I realize once you think about it some time and understand the terms it's not so complicated anymore. I hope this also helps anyone in understanding these terms.

Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:

sudo apt-get install bison flex

There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for "introduction to lex", there are plenty of good articles showing up.

I have no idea why the other answers didn't work for me (error 500) but this works

@GetMapping("")
public String getAll() {
    List<Entity> entityList = entityManager.findAll();
    List<JSONObject> entities = new ArrayList<JSONObject>();
    for (Entity n : entityList) {
        JSONObject Entity = new JSONObject();
        entity.put("id", n.getId());
        entity.put("address", n.getAddress());
        entities.add(entity);
    }
    return entities.toString();
}

First, run the app on simulator. Then, use command+s, or File -> Save Screenshot in Simulator to take necessary and appropriate shots. The screenshots will appear on your desktop by default.

A saw a different post that also had diacritical marks, which is great

s.replace(/[^a-zA-Z0-9À-ž\s]/g, "")

Perhaps a better way of handling errors in MVC is to apply the HandleError attribute to your controller or action and update the Shared/Error.aspx file to do what you want. The Model object on that page includes an Exception property as well as ControllerName and ActionName.

Had the same problem.

Fixed by adding the dependency

classpath 'com.google.gms:google-services:3.0.0'

to the root build.gradle.

You could specify type like this:

[string[]] $a = "This", "Is", "a", "cat"

Checking the type:

$a.GetType()

Confirms:

    IsPublic IsSerial Name                                     BaseType
    -------- -------- ----                                     --------
    True     True     String[]                                 System.Array

Outputting $a:

PS C:\> $a

For me the problem was that right after making the request, my main activity launched another activity. That superseded the dialog so it was never seen.

Building on the answer from @Brian-Fisher and answering the comments of some of the people on this post, I have a bunch of huge (and unnecessary) tables in my database so I wanted to skip their contents when copying, but keep the structure:

mysqldump -h <host> -u <username> -p <schema> --no-data > db-structure.sql
mysqldump -h <host> -u <username> -p <schema> --no-create-info --ignore-table=schema.table1 --ignore-table=schema.table2 > db-data.sql

The resulting two files are structurally sound but the dumped data is now ~500MB rather than 9GB, much better for me. I can now import these two files into another database for testing purposes without having to worry about manipulating 9GB of data or running out of disk space.

It is totally possible, i did something similar based on the example of Mike Sav. That's the html page and ther shoul be an external test.js file in the same folder

example.html:

<html>
<button type="button" value="Submit" onclick="myclick()" >
Click here~!
<div id='mylink'></div>
</button>
<script type="text/javascript">
function myclick(){
    var myLink = document.getElementById('mylink');
    myLink.onclick = function(){
            var script = document.createElement("script");
            script.type = "text/javascript";
            script.src = "./test.js"; 
            document.getElementsByTagName("head")[0].appendChild(script);
            return false;
    }
    document.getElementById('mylink').click();
}
</script>
</html>

test.js:

alert('hello world')

For .NET 4.0 and higher, you can compare elements in array or tuples using the StructuralComparisons type:

object[] a1 = { "string", 123, true };
object[] a2 = { "string", 123, true };
        
Console.WriteLine (a1 == a2);        // False (because arrays is reference types)
Console.WriteLine (a1.Equals (a2));  // False (because arrays is reference types)
        
IStructuralEquatable se1 = a1;
//Next returns True
Console.WriteLine (se1.Equals (a2, StructuralComparisons.StructuralEqualityComparer)); 

answer = None
while True:
    answer = raw_input("Do you like pie?")
    if answer in ("yes", "no"): break
    print "That is not a yes or a no"

Would give you what you want with no goto statement.

I have tried but above not working after research found below the solution.

SELECT * FROM my_table where DATE(start_date) > '2011-01-01';

I know this question has an accepted answer, but I feel that it doesn't work in all cases.

For completeness and since I spent too much time on this, here is what we did: we ended up using a function from php.js (which is a pretty nice library for those more familiar with PHP but also doing a little JavaScript every now and then):

http://phpjs.org/functions/strip_tags:535

It seemed to be the only piece of JavaScript code which successfully dealt with all the different kinds of input I stuffed into my application. That is, without breaking it – see my comments about the <script /> tag above.

Modify your web.config to display the server error details:

<system.web>
  <customErrors mode="Off" />
</system.web>

You may also need to remove/comment out the follow httpErrors section

  <system.webServer>
    <httpErrors errorMode="Custom">
      <remove statusCode="404" />
      <error statusCode="404" path="/Error/Error404" responseMode="ExecuteURL" />
      <remove statusCode="500" />
      <error statusCode="500" path="/Error/Error500" responseMode="ExecuteURL" />
      <remove statusCode="403" />
      <error statusCode="403" path="/Error/Error403" responseMode="ExecuteURL" />
    </httpErrors>
  </system.webServer>

From my experience if you directly have a server error, this may be caused from an assembly version mismatch.

Check what is declared in the web.config and the actual ddl in the bin folder's project.

You can make use of the SlimScroll plugin to make a div scrollable even if it is set to overflow: hidden;(i.e. scrollbar hidden).

You can also control touch scroll as well as the scroll speed using this plugin.

Hope this helps :)

I think you should give the data types of the column as NUMERIC or DOUBLE or FLOAT or REAL

Read http://sqlite.org/datatype3.html to more info.

public static double calculateInventoryTotal(Book[] arrayBooks) {

    final AtomicReference<BigDecimal> total = new AtomicReference<>(BigDecimal.ZERO);
    Optional.ofNullable(arrayBooks).map(Arrays::asList).ifPresent(books -> books.forEach(book -> total.accumulateAndGet(book.getPrice(), BigDecimal::add)));
    return total.get().doubleValue();

}

You can use javascript for this provblem. It's retrieve link from browser history.

<script>_x000D_
function goBack() {_x000D_
  window.history.back();_x000D_
}_x000D_
</script>

<button onclick="goBack()">Go Back</button>

If you won't go with regex:

"ABCDEFGHIJKLMNOP".toLowerCase().contains("gHi".toLowerCase())

Update Sept 2017: fs-promise has been deprecated in favour of fs-extra.

I haven't used it, but you could look into fs-promise. It's a node module that:

Proxies all async fs methods exposing them as Promises/A+ compatible promises (when, Q, etc). Passes all sync methods through as values.

1. Using the x509 module
openssl x509 ...
...

2 Using the ca module
openssl ca ...
...

You are missing the prelude to those commands.

This is a two-step process. First you set up your CA, and then you sign an end entity certificate (a.k.a server or user). Both of the two commands elide the two steps into one. And both assume you have a an OpenSSL configuration file already setup for both CAs and Server (end entity) certificates.

First, create a basic configuration file:

$ touch openssl-ca.cnf

Then, add the following to it:

HOME            = .
RANDFILE        = $ENV::HOME/.rnd

subjectKeyIdentifier   = hash

keyUsage               = keyCertSign, cRLSign

The fields above are taken from a more complex openssl.cnf (you can find it in /usr/lib/openssl.cnf), but I think they are the essentials for creating the CA certificate and private key.

Tweak the fields above to suit your taste. The defaults save you the time from entering the same information while experimenting with configuration file and command options.

I omitted the CRL-relevant stuff, but your CA operations should have them. See openssl.cnf and the related crl_ext section.

Then, execute the following. The -nodes omits the password or passphrase so you can examine the certificate. It's a really bad idea to omit the password or passphrase.

$ openssl req -x509 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

After the command executes, cacert.pem will be your certificate for CA operations, and cakey.pem will be the private key. Recall the private key does not have a password or passphrase.

You can dump the certificate with the following.

$ openssl x509 -in cacert.pem -text -noout

If you are developing and need to use your workstation as a server, then you may need to do the following for Chrome. Otherwise Chrome may complain a Common Name is invalid (ERR_CERT_COMMON_NAME_INVALID). I'm not sure what the relationship is between an IP address in the SAN and a CN in this instance.

# IPv4 localhost
IP.1     = 127.0.0.1

# IPv6 localhost
IP.2     = ::1

Then, create the server certificate request. Be sure to omit -x509*. Adding -x509 will create a certificate, and not a request.

$ openssl req -config openssl-server.cnf -newkey rsa:2048 -sha256 -nodes -out servercert.csr -outform PEM

After this command executes, you will have a request in servercert.csr and a private key in serverkey.pem.

And you can inspect it again.

$ openssl req -text -noout -verify -in servercert.csr

Next, you have to sign it with your CA.

You are almost ready to sign the server's certificate by your CA. The CA's openssl-ca.cnf needs two more sections before issuing the command.

First, open openssl-ca.cnf and add the following two sections.

####################################################################
[ signing_policy ]
countryName            = optional
stateOrProvinceName    = optional
localityName           = optional
organizationName       = optional
organizationalUnitName = optional
commonName             = supplied
emailAddress           = optional

####################################################################
[ signing_req ]
subjectKeyIdentifier   = hash
authorityKeyIdentifier = keyid,issuer
basicConstraints       = CA:FALSE
keyUsage               = digitalSignature, keyEncipherment

Second, add the following to the [ CA_default ] section of openssl-ca.cnf. I left them out earlier, because they can complicate things (they were unused at the time). Now you'll see how they are used, so hopefully they will make sense.

base_dir      = .
certificate   = $base_dir/cacert.pem   # The CA certifcate
private_key   = $base_dir/cakey.pem    # The CA private key
new_certs_dir = $base_dir              # Location for new certs after signing
database      = $base_dir/index.txt    # Database index file
serial        = $base_dir/serial.txt   # The current serial number

unique_subject = no  # Set to 'no' to allow creation of
                     # several certificates with same subject.

Third, touch index.txt and serial.txt:

$ touch index.txt
$ echo '01' > serial.txt

Then, perform the following:

$ openssl ca -config openssl-ca.cnf -policy signing_policy -extensions signing_req -out servercert.pem -infiles servercert.csr

You should see similar to the following:

Using configuration from openssl-ca.cnf
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName           :PRINTABLE:'US'
stateOrProvinceName   :ASN.1 12:'MD'
localityName          :ASN.1 12:'Baltimore'
commonName            :ASN.1 12:'Test CA'
emailAddress          :IA5STRING:'[email protected]'

Sign the certificate? [y/n]:Y

After the command executes, you will have a freshly minted server certificate in servercert.pem. The private key was created earlier and is available in serverkey.pem.

Finally, you can inspect your freshly minted certificate with the following:

$ openssl x509 -in servercert.pem -text -noout

Earlier, you added the following to CA_default: copy_extensions = copy. This copies extension provided by the person making the request.

If you omit copy_extensions = copy, then your server certificate will lack the Subject Alternate Names (SANs) like www.example.com and mail.example.com.

If you use copy_extensions = copy, but don't look over the request, then the requester might be able to trick you into signing something like a subordinate root (rather than a server or user certificate). Which means he/she will be able to mint certificates that chain back to your trusted root. Be sure to verify the request with openssl req -verify before signing.

If you omit unique_subject or set it to yes, then you will only be allowed to create one certificate under the subject's distinguished name.

unique_subject = yes            # Set to 'no' to allow creation of
                                # several ctificates with same subject.

Trying to create a second certificate while experimenting will result in the following when signing your server's certificate with the CA's private key:

Sign the certificate? [y/n]:Y
failed to update database
TXT_DB error number 2

So unique_subject = no is perfect for testing.

If you want to ensure the Organizational Name is consistent between self-signed CAs, Subordinate CA and End-Entity certificates, then add the following to your CA configuration files:

[ policy_match ]
organizationName = match

If you want to allow the Organizational Name to change, then use:

[ policy_match ]
organizationName = supplied

There are other rules concerning the handling of DNS names in X.509/PKIX certificates. Refer to these documents for the rules:

• RFC 5280, Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile
• RFC 6125, Representation and Verification of Domain-Based Application Service Identity within Internet Public Key Infrastructure Using X.509 (PKIX) Certificates in the Context of Transport Layer Security (TLS)
• RFC 6797, Appendix A, HTTP Strict Transport Security (HSTS)
• RFC 7469, Public Key Pinning Extension for HTTP
• CA/Browser Forum Baseline Requirements
• CA/Browser Forum Extended Validation Guidelines

RFC 6797 and RFC 7469 are listed, because they are more restrictive than the other RFCs and CA/B documents. RFC's 6797 and 7469 do not allow an IP address, either.

Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).

Instead, I used this method:

1. Close all but one instance of Visual Studio.
2. In the running instance, access the menu Tools->Extensions and Updates.
3. In that dialog, choose Online->Visual Studio Marketplace->Tools->Setup & Deployment.
4. From the list that appears, select Microsoft Visual Studio 2017 Installer Projects.

Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:

You can use fs.stat to check if target is a file or directory and you can use fs.access to check if you can write/read/execute the file. (remember to use path.resolve to get full path for the target)

Documentation:

• path.resolve
• fs.stat
• fs.access

Full example (TypeScript)

import * as fs from 'fs';
import * as path from 'path';

const targetPath = path.resolve(process.argv[2]);

function statExists(checkPath): Promise<fs.Stats> {
  return new Promise((resolve) => {
    fs.stat(checkPath, (err, result) => {
      if (err) {
        return resolve(undefined);
      }

      return resolve(result);
    });
  });
}

function checkAccess(checkPath: string, mode: number = fs.constants.F_OK): Promise<boolean> {
  return new Promise((resolve) => {
    fs.access(checkPath, mode, (err) => {
      resolve(!err);
    });
  });
}

(async function () {
  const result = await statExists(targetPath);
  const accessResult = await checkAccess(targetPath, fs.constants.F_OK);
  const readResult = await checkAccess(targetPath, fs.constants.R_OK);
  const writeResult = await checkAccess(targetPath, fs.constants.W_OK);
  const executeResult = await checkAccess(targetPath, fs.constants.X_OK);
  const allAccessResult = await checkAccess(targetPath, fs.constants.F_OK | fs.constants.R_OK | fs.constants.W_OK | fs.constants.X_OK);

  if (result) {
    console.group('stat');
    console.log('isFile: ', result.isFile());
    console.log('isDir: ', result.isDirectory());
    console.groupEnd();
  }
  else {
    console.log('file/dir does not exist');
  }

  console.group('access');
  console.log('access:', accessResult);
  console.log('read access:', readResult);
  console.log('write access:', writeResult);
  console.log('execute access:', executeResult);
  console.log('all (combined) access:', allAccessResult);
  console.groupEnd();

  process.exit(0);
}());

Old thread. But nevertheless( pun :) ).

 $less filename

less works efficiently if you don't want to edit and just look around which is the case for examining huge log files.

Search in less works like vi

Best part, it's available by default on most distros. So won't be problem for production environment as well.

There are many appropiate solution to this problem as mentioned above in this post, but i have found a small hack that can be inserrted in the script or pasted in the Chromes console (debugger) to achieve it:

jQuery(window).keydown(function(e) { if (e.keyCode == 123) debugger; });

This will cause execution to be paused when you hit F12.

@eeezyy's answer didn't work for me, although I'm using Spring Boot (2.0.4) and it may differ, but a variation here in 2018 works thus:

@Autowired
private HttpServletRequest request;

I think you are on the right track with COALESCE. See here for an example of building a comma-delimited string:

http://www.sqlteam.com/article/using-coalesce-to-build-comma-delimited-string

Making these 2 communicate

=IF(OR(AND(MID(K27,6,1)="N",(MID(K27,6,1)="C"),(MID(K27,6,1)="H"),(MID(K27,6,1)="I"),(MID(K27,6,1)="B"),(MID(K27,6,1)="F"),(MID(K27,6,1)="L"),(MID(K27,6,1)="M"),(MID(K27,6,1)="P"),(MID(K27,6,1)="R"),(MID(K27,6,1)="P"),ISTEXT(G27)="61"),AND(RIGHT(K27,2)=G27)),"Good","Review")

=IF(AND(RIGHT(K27,2)=G27),"Good","Review")

Just go to Publish -> Application File -> And change the effected dll publish status from prerequisite to include! This worked for me!

Here is an alternative solution:

class extendedWebBrowser : WebBrowser
{
    /// <summary>
    /// Default constructor which will make the browser to ignore all errors
    /// </summary>
    public extendedWebBrowser()
    {
        this.ScriptErrorsSuppressed = true;

        FieldInfo field = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
        {
             object axIWebBrowser2 = field.GetValue(this);
             axIWebBrowser2.GetType().InvokeMember("Silent", BindingFlags.SetProperty, null, axIWebBrowser2, new object[] { true });
        }
    }
}

These days, you can leverage the .NET library from VBA. The following works for me in Excel 2016. Returns the hash as uppercase hex.

Public Function SHA1(ByVal s As String) As String
    Dim Enc As Object, Prov As Object
    Dim Hash() As Byte, i As Integer

    Set Enc = CreateObject("System.Text.UTF8Encoding")
    Set Prov = CreateObject("System.Security.Cryptography.SHA1CryptoServiceProvider")

    Hash = Prov.ComputeHash_2(Enc.GetBytes_4(s))

    SHA1 = ""
    For i = LBound(Hash) To UBound(Hash)
        SHA1 = SHA1 & Hex(Hash(i) \ 16) & Hex(Hash(i) Mod 16)
    Next
End Function

Rather than create 2 temporary dfs you can just pass these as params within a dict using the DataFrame constructor:

pd.DataFrame({'email':sf.index, 'list':sf.values})

There are lots of ways to construct a df, see the docs

See here: http://docs.python.org/using/windows.html

pythonw.exe "This suppresses the terminal window on startup."

First create temporary cookie using tempnam() function:

$ckfile = tempnam ("/tmp", "CURLCOOKIE");

Then execute curl init witch saves the cookie as a temporary file:

$ch = curl_init ("http://uri.com/");
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec ($ch);

Or visit a page using the cookie stored in the temporary file:

$ch = curl_init ("http://somedomain.com/cookiepage.php");
curl_setopt ($ch, CURLOPT_COOKIEFILE, $ckfile);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec ($ch);

This will initialize the cookie for the page:

curl_setopt ($ch, CURLOPT_COOKIEFILE, $ckfile);

Generate numbers between 0 and 65535 then just subtract 32768

Check this thread out: read and write image file.

Also, have a look at this other question at Stackoverflow.

They are exactly the same character. See: http://en.wikipedia.org/wiki/Dash

Barring browser bugs they will display the same in all cases, so the only difference would be concerning code readability, which would point to —.

Or, if you are using UTF-8 as a charset in your HTML document, you could enter the character directly. That would also display exactly the same.

Import specific methods inside of curly brackets

import { map, tail, times, uniq } from 'lodash';

Pros:

• Only one import line(for a decent amount of functions)
• More readable usage: map() instead of _.map() later in the javascript code.

Cons:

• Every time we want to use a new function or stop using another - it needs to be maintained and managed

<init-param> and <context-param> are static parameters which are stored in web.xml file. If you have any data which doesn't change frequently you can store it in one of them.

If you want to store particular data which is confined to a particular servlet scope, then you can use <init-param> .Anything you declare inside <init-param> is only accessible only for that particular servlet.The init-param is declared inside the <servlet> tag.

<servlet>
     <display-name>HelloWorldServlet</display-name>
     <servlet-name>HelloWorldServlet</servlet-name>
     <init-param>
         <param-name>Greetings</param-name>
         <param-value>Hello</param-value>
     </init-param>
</servlet>

and you can access those parameters in the servlet as follows:

out.println(getInitParameter("Greetings"));

If you want to store data which is common for whole application and if it doesn't change frequently you can use <context-param> instead of servletContext.setAttribute() method of the application context. For more information regarding usage of <context-param> VS ServletContext.setAttribute() have a look at this question. context-param are declared under the tag web-app. You can declare and access the <context-param> as follows

<web-app>
    <context-param>
        <param-name>Country</param-name>
        <param-value>India</param-value>
    </context-param>
    <context-param>
        <param-name>Age</param-name>
        <param-value>24</param-value>
    </context-param>
</web-app>

Usage in the application either in a JSP or Servlet

getServletContext().getInitParameter("Country");
getServletContext().getInitParameter("Age");

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

Though Dan Lowe's excellent answer very thoroughly answered the OP's question about the difference between PUT and PATCH, its answer to the question of why PATCH is not idempotent is not quite correct.

To show why PATCH isn't idempotent, it helps to start with the definition of idempotence (from Wikipedia):

The term idempotent is used more comprehensively to describe an operation that will produce the same results if executed once or multiple times [...] An idempotent function is one that has the property f(f(x)) = f(x) for any value x.

In more accessible language, an idempotent PATCH could be defined as: After PATCHing a resource with a patch document, all subsequent PATCH calls to the same resource with the same patch document will not change the resource.

Conversely, a non-idempotent operation is one where f(f(x)) != f(x), which for PATCH could be stated as: After PATCHing a resource with a patch document, subsequent PATCH calls to the same resource with the same patch document do change the resource.

To illustrate a non-idempotent PATCH, suppose there is a /users resource, and suppose that calling GET /users returns a list of users, currently:

[{ "id": 1, "username": "firstuser", "email": "[email protected]" }]

Rather than PATCHing /users/{id}, as in the OP's example, suppose the server allows PATCHing /users. Let's issue this PATCH request:

PATCH /users
[{ "op": "add", "username": "newuser", "email": "[email protected]" }]

Our patch document instructs the server to add a new user called newuser to the list of users. After calling this the first time, GET /users would return:

[{ "id": 1, "username": "firstuser", "email": "[email protected]" },
 { "id": 2, "username": "newuser", "email": "[email protected]" }]

Now, if we issue the exact same PATCH request as above, what happens? (For the sake of this example, let's assume that the /users resource allows duplicate usernames.) The "op" is "add", so a new user is added to the list, and a subsequent GET /users returns:

[{ "id": 1, "username": "firstuser", "email": "[email protected]" },
 { "id": 2, "username": "newuser", "email": "[email protected]" },
 { "id": 3, "username": "newuser", "email": "[email protected]" }]

The /users resource has changed again, even though we issued the exact same PATCH against the exact same endpoint. If our PATCH is f(x), f(f(x)) is not the same as f(x), and therefore, this particular PATCH is not idempotent.

Although PATCH isn't guaranteed to be idempotent, there's nothing in the PATCH specification to prevent you from making all PATCH operations on your particular server idempotent. RFC 5789 even anticipates advantages from idempotent PATCH requests:

A PATCH request can be issued in such a way as to be idempotent, which also helps prevent bad outcomes from collisions between two PATCH requests on the same resource in a similar time frame.

In Dan's example, his PATCH operation is, in fact, idempotent. In that example, the /users/1 entity changed between our PATCH requests, but not because of our PATCH requests; it was actually the Post Office's different patch document that caused the zip code to change. The Post Office's different PATCH is a different operation; if our PATCH is f(x), the Post Office's PATCH is g(x). Idempotence states that f(f(f(x))) = f(x), but makes no guarantes about f(g(f(x))).

The original question is about Bootstrap 3 and that supports IE8 and 9 so Flexbox would be the best option but it's not part of my answer due the lack of support, see http://caniuse.com/#feat=flexbox and toggle the IE box. Pretty bad, eh?

2 ways:

1. Display-table: You can muck around with turning the row into a display:table and the col- into display:table-cell. It works buuuut the limitations of tables are there, among those limitations are the push and pull and offsets won't work. Plus, I don't know where you're using this -- at what breakpoint. You should make the image full width and wrap it inside another container to put the padding on there. Also, you need to figure out the design on mobile, this is for 768px and up. When I use this, I redeclare the sizes and sometimes I stick importants on them because tables take on the width of the content inside them so having the widths declared again helps this. You will need to play around. I also use a script but you have to change the less files to use it or it won't work responsively.

Jquery later allowed you to to find the parents with the .parents() method.

Hence I recommend using:

var $div = $('#divid').parents('div[class^="div-a"]');

This gives all parent nodes matching the selector. To get the first parent matching the selector use:

var $div = $('#divid').parents('div[class^="div-a"]').eq(0);

I don't see any problem with that. Pre-ARC, I've always made my IBOutlets assign, as they're already retained by their superviews. If you make them weak, you shouldn't have to nil them out in viewDidUnload, as you point out.

One caveat: You can support iOS 4.x in an ARC project, but if you do, you can't use weak, so you'd have to make them assign, in which case you'd still want to nil the reference in viewDidUnload to avoid a dangling pointer. Here's an example of a dangling pointer bug I've experienced:

A UIViewController has a UITextField for zip code. It uses CLLocationManager to reverse geocode the user's location and set the zip code. Here's the delegate callback:

-(void)locationManager:(CLLocationManager *)manager
   didUpdateToLocation:(CLLocation *)newLocation
          fromLocation:(CLLocation *)oldLocation {
    Class geocoderClass = NSClassFromString(@"CLGeocoder");
    if (geocoderClass && IsEmpty(self.zip.text)) {
        id geocoder = [[geocoderClass alloc] init];
        [geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) {
            if (self.zip && IsEmpty(self.zip.text)) {
                self.zip.text = [[placemarks objectAtIndex:0] postalCode];
            }
        }];    
    }
    [self.locationManager stopUpdatingLocation];
}

I found that if I dismissed this view at the right time and didn't nil self.zip in viewDidUnload, the delegate callback could throw a bad access exception on self.zip.text.

You seem to have the quote marks (") embedded in your string at the start and the end. These are not needed and are illegal characters in a path. How are you initializing the string with the path?

This can be seen from the debugger visualizer, as the string starts with "\" and ends with \"", it shows that the quotes are part of the string, when they shouldn't be.

You can do two thing - a regular escaped string (using \) or a verbatim string literal (that starts with a @):

  string str = "C:\\Program Files (x86)\\test software\\myapp\\demo.exe";

Or:

  string verbatim = @"C:\Program Files (x86)\test software\myapp\demo.exe";

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

The cssrewrite filter is not compatible with the @bundle notation for now. So you have two choices:

• Reference the CSS files in the web folder (after: console assets:install --symlink web)

  {% stylesheets '/bundles/myCompany/css/*." filter="cssrewrite" %}
  

• Use the cssembed filter to embed images in the CSS like this.

  {% stylesheets '@MyCompanyMyBundle/Resources/assets/css/*.css' filter="cssembed" %}

You know, using a custom deleter isn't the best way to go, as you will have to mention it all over your code.
Instead, as you are allowed to add specializations to namespace-level classes in ::std as long as custom types are involved and you respect the semantics, do that:

Specialize std::default_delete:

template <>
struct ::std::default_delete<Bar> {
    default_delete() = default;
    template <class U>
    constexpr default_delete(default_delete<U>) noexcept {}
    void operator()(Bar* p) const noexcept { destroy(p); }
};

And maybe also do std::make_unique():

template <>
inline ::std::unique_ptr<Bar> ::std::make_unique<Bar>() {
    auto p = create();
    if (!p)
        throw std::runtime_error("Could not `create()` a new `Bar`.");
    return { p };
}

You can expose the service in two different endpoints. the SOAP one can use the binding that support SOAP e.g. basicHttpBinding, the RESTful one can use the webHttpBinding. I assume your REST service will be in JSON, in that case, you need to configure the two endpoints with the following behaviour configuration

<endpointBehaviors>
  <behavior name="jsonBehavior">
    <enableWebScript/>
  </behavior>
</endpointBehaviors>

An example of endpoint configuration in your scenario is

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="json" binding="webHttpBinding"  behaviorConfiguration="jsonBehavior" contract="ITestService"/>
  </service>
</services>

so, the service will be available at

• http://www.example.com/soap
• http://www.example.com/json

Apply [WebGet] to the operation contract to make it RESTful. e.g.

public interface ITestService
{
   [OperationContract]
   [WebGet]
   string HelloWorld(string text)
}

Note, if the REST service is not in JSON, parameters of the operations can not contain complex type.

Reply to the post for SOAP and RESTful POX(XML)

For plain old XML as return format, this is an example that would work both for SOAP and XML.

[ServiceContract(Namespace = "http://test")]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "accounts/{id}")]
    Account[] GetAccount(string id);
}

POX behavior for REST Plain Old XML

<behavior name="poxBehavior">
  <webHttp/>
</behavior>

Endpoints

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="xml" binding="webHttpBinding"  behaviorConfiguration="poxBehavior" contract="ITestService"/>
  </service>
</services>

Service will be available at

• http://www.example.com/soap
• http://www.example.com/xml

REST request try it in browser,

http://www.example.com/xml/accounts/A123

SOAP request client endpoint configuration for SOAP service after adding the service reference,

  <client>
    <endpoint address="http://www.example.com/soap" binding="basicHttpBinding"
      contract="ITestService" name="BasicHttpBinding_ITestService" />
  </client>

in C#

TestServiceClient client = new TestServiceClient();
client.GetAccount("A123");

Another way of doing it is to expose two different service contract and each one with specific configuration. This may generate some duplicates at code level, however at the end of the day, you want to make it working.

This is not related to performance at all. But consider this: you are using two libraries called Foo and Bar:

using namespace foo;
using namespace bar;

Everything works fine, and you can call Blah() from Foo and Quux() from Bar without problems. But one day you upgrade to a new version of Foo 2.0, which now offers a function called Quux(). Now you've got a conflict: Both Foo 2.0 and Bar import Quux() into your global namespace. This is going to take some effort to fix, especially if the function parameters happen to match.

If you had used foo::Blah() and bar::Quux(), then the introduction of foo::Quux() would have been a non-event.

Try something like this:

<html>
  <body>

    <script type="text/javascript">
        function doSomething(event) {
          var source = event.target || event.srcElement;
          console.log(source);
          alert('test');
          if(window.event) {
            // IE8 and earlier
            // doSomething
           } else if(e.which) {
            // IE9/Firefox/Chrome/Opera/Safari
            // doSomething
           }
        }
     </script>

    <button onclick="doSomething('param')" id="id_button">
      action
    </button>

  </body>      
</html>

A few things:

First, I don't think you really need a validation error for a radio fieldset because you could just have one of the fields checked by default. Most people would rather correct something then provide something. For instance:

   Age: (*) 12 - 18 | () 19 - 30 | 31 - 50 

is more likely to be changed to the right answer as the person DOESN'T want it to go to the default. If they see it blank, they are more likely to think "none of your business" and skip it.

Second, I was able to get the effect I think you are wanting without any positioning properties. You just add padding-right to the form (or the div of the form, whatever) to provide enough room for your error and make sure your error will fit in that area. Then, you have a pre-set up css class called "error" and you set it as having a negative margin-top roughly the height of your input field and a margin-left about the distance from the left to where your padding-right should start. I tried this out, it's not great, but it works with three properties and requires no floats or absolutes:

   <style type="text/css">
    .error {
        width: 13em; /* Ensures that the div won't exceed right padding of form */
        margin-top: -1.5em;  /*Moves the div up to the same level as input */
        margin-left: 11em;   /*Moves div to the right */
        font-size: .9em;     /*Makes sure that the error div is smaller than input */
    }

   <form>
   <label for="name">Name:</label><input id="name" type="textbox" />
   <div class="error"><<< This field is required!</div>
   <label for="numb">Phone:</label><input id="numb" type="textbox" />
   <div class="error"><<< This field is required!</div>
   </form>

For logout button on last screen of app, use this code on logout button listener to finish all open previous activities, and your problem is solved.

{
Intent intent = new Intent(this, loginScreen.class);
ntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}

As commented by David Thomas, descendants of those child elements will (likely) inherit most of the styles assigned to those child elements.

You need to wrap your .myTestClass inside an element and apply the styles to descendants by adding .wrapper * descendant selector. Then, add .myTestClass > * child selector to apply the style to the elements children, not its grand children. For example like this:

JSFiddle - DEMO

.wrapper * {_x000D_
    color: blue;_x000D_
    margin: 0 100px; /* Only for demo */_x000D_
}_x000D_
.myTestClass > * {_x000D_
    color:red;_x000D_
    margin: 0 20px;_x000D_
}

<div class="wrapper">_x000D_
    <div class="myTestClass">Text 0_x000D_
        <div>Text 1</div>_x000D_
        <span>Text 1</span>_x000D_
        <div>Text 1_x000D_
            <p>Text 2</p>_x000D_
            <div>Text 2</div>_x000D_
        </div>_x000D_
        <p>Text 1</p>_x000D_
    </div>_x000D_
    <div>Text 0</div>_x000D_
</div>

I know this has been answered for some time, but there are some points that some may want to know about using PYTHONPATH instead of PATH in their environment variable. I have outlined an explanation of running python scripts with cronjobs that deals with the modified environment in a different way (found here). Thought it would be of some good for those who, like me, needed just a bit more than this answer provided.

Try doing this:

 textValue= textValue.replaceAll("\n", "");
 textValue= textValue.replaceAll("\t", "");
 textValue= textValue.replaceAll("\\n", "");
 textValue= textValue.replaceAll("\\t", "");
 textValue= textValue.replaceAll("\r", "");
 textValue= textValue.replaceAll("\\r", "");
 textValue= textValue.replaceAll("\r\n", "");
 textValue= textValue.replaceAll("\\r\\n", "");

I am not very good in using sophisticated regular expressions, so I'd do such task in the following way:

files <- list.files()
dbf.files <- files[-grep(".xml", files, fixed=T)]

First line just lists all files from working dir. Second one drops everything containing ".xml" (grep returns indices of such strings in 'files' vector; subsetting with negative indices removes corresponding entries from vector). "fixed" argument for grep function is just my whim, as I usually want it to peform crude pattern matching without Perl-style fancy regexprs, which may cause surprise for me.

I'm aware that such solution simply reflects drawbacks in my education, but for a novice it may be useful =) at least it's easy.

To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

COPY ./files/. /files/

When generating mapping files using doctrine I ran into same issue. I fixed it by removing all comments that some fields had in the database.

I arrived at this page looking to turn off scale mode for good, so I figured I would share what I found:

Running this in my host's terminal worked like a charm for me.

You've done twice the checking when you create

${someObject.someProperty != null} ? ${someObject.someProperty}

You should do it clean and simple as below.

<td th:text="${someObject.someProperty} ? ${someObject.someProperty} : 'null value!'"></td>

You can add the rules based on that selector using .rules("add", options), just remove any rules you want class based out of your validate options, and after calling $(".formToValidate").validate({... });, do this:

$(".checkBox").rules("add", { 
  required:true,  
  minlength:3
});

The Problem

In MySQL, certain words like SELECT, INSERT, DELETE etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.

As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):

Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.

...

If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.

...

The identifier quote character is the backtick ("`"):

A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.

• ADD
• AND
• BEFORE
• BY
• CALL
• CASE
• CONDITION
• DELETE
• DESC
• DESCRIBE
• FROM
• GROUP
• IN
• INDEX
• INSERT
• INTERVAL
• IS
• KEY
• LIKE
• LIMIT
• LONG
• MATCH
• NOT
• OPTION
• OR
• ORDER
• PARTITION
• RANK
• REFERENCES
• SELECT
• TABLE
• TO
• UPDATE
• WHERE

The Solution

You have two options.

1. Don't use reserved words as identifiers

The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.

Doing this has a couple of advantages:

• It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.

• The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.

Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.

2. Use backticks

If renaming the table or column isn't possible, wrap the offending identifier in backticks (`) as described in the earlier quote from 10.2 Schema Object Names.

An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

Similarly, the query from the question can be fixed by wrapping the keyword key in backticks, as shown below:

INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)";               ^   ^

// Use this version to capture the full extended desktop (i.e. multiple screens)

Bitmap screenshot = new Bitmap(SystemInformation.VirtualScreen.Width, 
                               SystemInformation.VirtualScreen.Height, 
                               PixelFormat.Format32bppArgb);
Graphics screenGraph = Graphics.FromImage(screenshot);
screenGraph.CopyFromScreen(SystemInformation.VirtualScreen.X, 
                           SystemInformation.VirtualScreen.Y, 
                           0, 
                           0, 
                           SystemInformation.VirtualScreen.Size, 
                           CopyPixelOperation.SourceCopy);

screenshot.Save("Screenshot.png", System.Drawing.Imaging.ImageFormat.Png);

-> is for pointers to a class instance

. is for class instances

:: is for classnames - for example when using a static member

If you have Mockito 1.9.5 or higher, there is a new static method that can make the Answer object for you. You need to write something like

import static org.mockito.Mockito.when;
import static org.mockito.AdditionalAnswers.returnsFirstArg;

when(myMock.myFunction(anyString())).then(returnsFirstArg());

or alternatively

doAnswer(returnsFirstArg()).when(myMock).myFunction(anyString());

Note that the returnsFirstArg() method is static in the AdditionalAnswers class, which is new to Mockito 1.9.5; so you'll need the right static import.

A Meteor app does not, by default, add any X-Powered-By headers to HTTP responses, as you might find in various PHP apps. The headers look like:

$ curl -I https://atmosphere.meteor.com  HTTP/1.1 200 OK content-type: text/html; charset=utf-8 date: Tue, 31 Dec 2013 23:12:25 GMT connection: keep-alive 

However, this doesn't mask that Meteor was used. Viewing the source of a Meteor app will look very distinctive.

<script type="text/javascript"> __meteor_runtime_config__ = {"meteorRelease":"0.6.3.1","ROOT_URL":"http://atmosphere.meteor.com","serverId":"62a4cf6a-3b28-f7b1-418f-3ddf038f84af","DDP_DEFAULT_CONNECTION_URL":"ddp+sockjs://ddp--****-atmosphere.meteor.com/sockjs"}; </script> 

If you're trying to avoid people being able to tell you are using Meteor even by viewing source, I don't think that's possible.

<asp:FileUpload ID="FileUploadExcel" ClientIDMode="Static" runat="server" />
<asp:Button ID="btnUpload" ClientIDMode="Static" runat="server" Text="Upload Excel File" />

.

$('#btnUpload').click(function () {
    var uploadpath = $('#FileUploadExcel').val();
    var fileExtension = uploadpath.substring(uploadpath.lastIndexOf(".") + 1, uploadpath.length);

    if ($('#FileUploadExcel').val().length == 0) {
        // write error message
        return false;
    }

    if (fileExtension == "xls" || fileExtension == "xlsx") {
        //write code for success
    }
    else {
        //error code - select only excel files
        return false;
    }

});

The wildcard library efficiently does both glob and regex filename matching:

http://code.google.com/p/wildcard/

The implementation is succinct -- JAR is only 12.9 kilobytes.

It looks like you are passing an NSString parameter where you should be passing an NSData parameter:

NSError *jsonError;
NSData *objectData = [@"{\"2\":\"3\"}" dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
                                      options:NSJSONReadingMutableContainers 
                                        error:&jsonError];

In SQL*Plus, you can do something very similar

SQL> variable v_emp_id number;
SQL> select 1234 into :v_emp_id from dual;

      1234
----------
      1234

SQL> select *
  2    from emp
  3   where empno = :v_emp_id;

no rows selected

In SQL Developer, if you run a statement that has any number of bind variables (prefixed with a colon), you'll be prompted to enter values. As Alex points out, you can also do something similar using the "Run Script" function (F5) with the alternate EXEC syntax Alex suggests does.

variable v_count number;
variable v_emp_id number;
exec :v_emp_id := 1234;
exec select count(1) into :v_count from emp;
select *
  from emp
 where empno = :v_emp_id
exec print :v_count;

To get actual hour, minute and seconds as appear on watch try this code

val sec = (milliSec/1000) % 60
val min = ((milliSec/1000) / 60) % 60
val hour = ((milliSec/1000) / 60) / 60

Here is a sample code

strFileName = "c:\test.xls"

Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = True

Set objWorkbook = objExcel.Workbooks.Add()
objWorkbook.SaveAs(strFileName)

objExcel.Quit

They are related values, and kept consistent by the property setter/getter methods (and using the fact that frame is a purely synthesized value, not backed by an actual instance variable).

The main equations are:

frame.origin = center - bounds.size / 2

(which is the same as)

center = frame.origin + bounds.size / 2

(and there’s also)

frame.size = bounds.size

That's not code, just equations to express the invariant between the three properties. These equations also assume your view's transform is the identity, which it is by default. If it's not, then bounds and center keep the same meaning, but frame can change. Unless you're doing non-right-angle rotations, the frame will always be the transformed view in terms of the superview's coordinates.

This stuff is all explained in more detail with a useful mini-library here:

Just chain them together:

.a.b {
  color: #666;
}

mmm is very simple guys

for( int i = model.getRowCount() - 1; i >= 0; i-- )
{
    model.removeRow(i);
}

You have to do the following:

if "%1" == "" (
    echo The variable is empty
) ELSE (
    echo The variable contains %1
)

or

public class Hbutil {

    private static SessionFactory sessionFactory;
    private static ServiceRegistry serviceRegistry;

    private static SessionFactory configureSessionFactory() throws HibernateException {
        Configuration configuration = new Configuration();
        configuration.configure();
        serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();        
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        return sessionFactory;
    }

    public static SessionFactory getSessionFactory() {
        return configureSessionFactory();

    }
}

Use the optional font argument to turtle.write(), from the docs:

turtle.write(arg, move=False, align="left", font=("Arial", 8, "normal"))
 Parameters:

• arg – object to be written to the TurtleScreen
• move – True/False
• align – one of the strings “left”, “center” or right”
• font – a triple (fontname, fontsize, fonttype)

So you could do something like turtle.write("messi fan", font=("Arial", 16, "normal")) to change the font size to 16 (default is 8).
