If you have custom attributes in appsetting. move your

     <configSections> 
     </configSections>

tag to the first child in the <confuguration>.

I had a similar problem rejecting localhost and 127.0.0.1. cmd(admin) netstat -anb found the port running on 169.254.80.80 (dont know were that ip came from because my network ip was 10.0.0.5. after putting in this IP it worked. This Gives correct IP:

IPAddress ipAddress = ipHostInfo.AddressList[0];
Console.WriteLine(ipAddress.ToString());

What worked for me is moving my project as it was on the desktop (C:\Users\lachezar.l\Desktop\MyFolder) to (C:\0\MyFolder) which as you can see uses shorter path and reducing it solved the problem.

Use the following code:

foreach (string line in File.ReadAllLines(fileName))

This was a HUGE difference in reading performance.

It comes at the cost of memory consumption, but totally worth it!

My problem was something like that:

FileStream ms = new FileStream(path, FileMode.Open, FileAccess.ReadWrite);

but instead of using path I should use File.FullName... I don't know if it's going to help anyone else, just passing my own experience with this erro given!

It may be easier to use XPath to locate the nodes that you wish to delete. This stackoverflow thread might give you some ideas.

In your case you will find the four nodes that you want using this expression:

XmlDocument doc = new XmlDocument();
doc.Load(fileName);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");

When your code does the following:

1. Checks the current user has permission to do something.
2. Carries out the action that needs the entitlements checked in 1.

You run the risk that the permissions change between 1 and 2 because you can't predict what else will be happening on the system at runtime. Therefore, your code should handle the situation where an UnauthorisedAccessException is thrown even if you have previously checked permissions.

Note that the SecurityManager class is used to check CAS permissions and doesn't actually check with the OS whether the current user has write access to the specified location (through ACLs and ACEs). As such, IsGranted will always return true for locally running applications.

Example (derived from Josh's example):

//1. Provide early notification that the user does not have permission to write.
FileIOPermission writePermission = new FileIOPermission(FileIOPermissionAccess.Write, filename);
if(!SecurityManager.IsGranted(writePermission))
{
    //No permission. 
    //Either throw an exception so this can be handled by a calling function
    //or inform the user that they do not have permission to write to the folder and return.
}

//2. Attempt the action but handle permission changes.
try
{
    using (FileStream fstream = new FileStream(filename, FileMode.Create))
    using (TextWriter writer = new StreamWriter(fstream))
    {
        writer.WriteLine("sometext");
    }
}
catch (UnauthorizedAccessException ex)
{
    //No permission. 
    //Either throw an exception so this can be handled by a calling function
    //or inform the user that they do not have permission to write to the folder and return.
}

It's tricky and not recommended to try to programatically calculate the effective permissions from the folder based on the raw ACLs (which are all that are available through the System.Security.AccessControl classes). Other answers on Stack Overflow and the wider web recommend trying to carry out the action to know whether permission is allowed. This post sums up what's required to implement the permission calculation and should be enough to put you off from doing this.

Add the maven repository outside the buildscript configuration block of your main build.gradle file as follows:

repositories {
        maven {
            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
        }
    }

Make sure that you add them after the following:

apply plugin: 'com.android.application'

Firebug is great, but Safari provides its own built-in development tools.

If you haven't already tried Safari's development kit, go to Safari-->Preferences-->Advanced, and check the box next to "Show Develop menu in menu bar".

Once you have the Develop menu enabled, you can use the Web Inspector to get a lot of the same functionality that Firebug provides.

set TEXT_T="myfile.txt"
set /a c=1

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (

    echo Output file is %OUTPUT_FILE_NAME%
    echo %%i, %c%

Your 0xED 0x6E 0x2C 0x20 bytes correspond to "ín, " in ISO-8859-1, so it looks like your content is in ISO-8859-1, not UTF-8. Tell your data provider about it and ask them to fix it, because if it doesn't work for you it probably doesn't work for other people either.

Now there are a few ways to work it around, which you should only use if you cannot load the XML normally. One of them would be to use utf8_encode(). The downside is that if that XML contains both valid UTF-8 and some ISO-8859-1 then the result will contain mojibake. Or you can try to convert the string from UTF-8 to UTF-8 using iconv() or mbstring, and hope they'll fix it for you. (they won't, but you can at least ignore the invalid characters so you can load your XML)

Or you can take the long, long road and validate/fix the sequences by yourself. That will take you a while depending on how familiar you are with UTF-8. Perhaps there are libraries out there that would do that, although I don't know any.

Either way, notify your data provider that they're sending invalid data so that they can fix it.

Here's a partial fix. It will definitely not fix everything, but will fix some of it. Hopefully enough for you to get by until your provider fix their stuff.

function fix_latin1_mangled_with_utf8_maybe_hopefully_most_of_the_time($str)
{
    return preg_replace_callback('#[\\xA1-\\xFF](?![\\x80-\\xBF]{2,})#', 'utf8_encode_callback', $str);
}

function utf8_encode_callback($m)
{
    return utf8_encode($m[0]);
}

What I did:

1. Deleted that particular library's folder
2. composer update --prefer-source vendor/library-name

It fetches the library again along with it's git repo

I suggest you do it a different way.

In the following code I set as a Range the column with the sports name F and loop through each cell of it, check if it is "hockey" and if yes I insert the values in the other sheet one by one, by using Offset.

I do not think it is very complicated and even if you are just learning VBA, you should probably be able to understand every step. Please let me know if you need some clarification

Sub TestThat()

'Declare the variables
Dim DataSh As Worksheet
Dim HokySh As Worksheet
Dim SportsRange As Range
Dim rCell As Range
Dim i As Long

'Set the variables
Set DataSh = ThisWorkbook.Sheets("Data")
Set HokySh = ThisWorkbook.Sheets("Hoky")

Set SportsRange = DataSh.Range(DataSh.Cells(3, 6), DataSh.Cells(Rows.Count, 6).End(xlUp))
    'I went from the cell row3/column6 (or F3) and go down until the last non empty cell

    i = 2

    For Each rCell In SportsRange 'loop through each cell in the range

        If rCell = "hockey" Then 'check if the cell is equal to "hockey"

            i = i + 1                                'Row number (+1 everytime I found another "hockey")
            HokySh.Cells(i, 2) = i - 2               'S No.
            HokySh.Cells(i, 3) = rCell.Offset(0, -1) 'School
            HokySh.Cells(i, 4) = rCell.Offset(0, -2) 'Background
            HokySh.Cells(i, 5) = rCell.Offset(0, -3) 'Age

        End If

    Next rCell

End Sub

If all you want to do is iterate in reverse, try this:

// iterate backwards
nextIndex = (currentIndex == 0) ? [myArray count] - 1 : (currentIndex - 1) % [myArray count];

You can do the [myArrayCount] once and save it to a local variable (I think its expensive), but I’m also guessing that the compiler will pretty much do the same thing with the code as written above.

A more native pandas approach is to apply a replace function as below:

def multiple_replace(dict, text):
  # Create a regular expression  from the dictionary keys
  regex = re.compile("(%s)" % "|".join(map(re.escape, dict.keys())))

  # For each match, look-up corresponding value in dictionary
  return regex.sub(lambda mo: dict[mo.string[mo.start():mo.end()]], text) 

Once you defined the function, you can apply it to your dataframe.

di = {1: "A", 2: "B"}
df['col1'] = df.apply(lambda row: multiple_replace(di, row['col1']), axis=1)

In views with {{}} and/or ng-model, Angular is setting up $watch()es for you behind the scenes.

By default $watch compares by reference. If you set the third parameter to $watch to true, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:

$scope.$watch('myModel', function() { ... }, true);

Update: Angular v1.2 added a new method for this, `$watchCollection():

$scope.$watchCollection('myModel', function() { ... });

Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.

The operators delete and delete [] are used respectively to destroy the objects created with new and new[], returning to the allocated memory left available to the compiler's memory manager.

Objects created with new must necessarily be destroyed with delete, and that the arrays created with new[] should be deleted with delete[].

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

Include the type specifier in your format expression:

>>> a = 10.1234
>>> f'{a:.2f}'
'10.12'

Static variable in a header file:

say 'common.h' has

static int zzz;

This variable 'zzz' has internal linkage (This same variable can not be accessed in other translation units). Each translation unit which includes 'common.h' has it's own unique object of name 'zzz'.

Static variable in a class:

Static variable in a class is not a part of the subobject of the class. There is only one copy of a static data member shared by all the objects of the class.

$9.4.2/6 - "Static data members of a class in namespace scope have external linkage (3.5).A local class shall not have static data members."

So let's say 'myclass.h' has

struct myclass{
   static int zzz;        // this is only a declaration
};

and myclass.cpp has

#include "myclass.h"

int myclass::zzz = 0           // this is a definition, 
                               // should be done once and only once

and "hisclass.cpp" has

#include "myclass.h"

void f(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

and "ourclass.cpp" has

#include "myclass.h"
void g(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

So, class static members are not limited to only 2 translation units. They need to be defined only once in any one of the translation units.

Note: usage of 'static' to declare file scope variable is deprecated and unnamed namespace is a superior alternate

Use shortcut: Ctrl+Q. You can customize in Settings

There are multiple ways to set profiles for your springboot application.

1. You can add this in your property file:

   spring.profiles.active=dev
   

2. Programmatic way:

   SpringApplication.setAdditionalProfiles("dev");
   

3. Tests make it very easy to specify what profiles are active

   @ActiveProfiles("dev")
   

4. In a Unix environment

   export spring_profiles_active=dev
   

5. JVM System Parameter

   -Dspring.profiles.active=dev
   

Example: Running a springboot jar file with profile.

java -jar -Dspring.profiles.active=dev application.jar

This is not a shorthand for $(document).ready().

The code you posted boxes the inside code and makes jQuery available as $ without polluting the global namespace. This can be used when you want to use both prototype and jQuery on one page.

Documented here: http://learn.jquery.com/using-jquery-core/avoid-conflicts-other-libraries/#use-an-immediately-invoked-function-expression

Between 3-50 characters. Can contain lowercase letters, numbers and special characters - dot(.), dash(-), underscore(_) and at the rate(@).

foreach (GridViewRow gvr in gvMyGridView.Rows)
{
    string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}

You can use this code while doing an iteration with foreach or for any GridView event like OnRowDataBound.

Here you can input multiple values for DataKeyNames by separating with comma ,. For example, DataKeyNames="ProductID,ItemID,OrderID".

You can now access each of DataKeys by providing its index like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();

You can also use Key Name instead of its index to get the values from DataKeyNames collection like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();

Using individual regular expressions to test the different parts would be considerably easier than trying to get one single regular expression to cover all of them. It also makes it easier to add or remove validation criteria.

Note, also, that your usage of .filter() was incorrect; it will always return a jQuery object (which is considered truthy in JavaScript). Personally, I'd use an .each() loop to iterate over all of the inputs, and report individual pass/fail statuses. Something like the below:

$(".buttonClick").click(function () {

    $("input[type=text]").each(function () {
        var validated =  true;
        if(this.value.length < 8)
            validated = false;
        if(!/\d/.test(this.value))
            validated = false;
        if(!/[a-z]/.test(this.value))
            validated = false;
        if(!/[A-Z]/.test(this.value))
            validated = false;
        if(/[^0-9a-zA-Z]/.test(this.value))
            validated = false;
        $('div').text(validated ? "pass" : "fail");
        // use DOM traversal to select the correct div for this input above
    });
});

Working demo

Try this.

public class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        var json = config.Formatters.JsonFormatter;
        json.SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/json"));
        config.Formatters.Remove(config.Formatters.XmlFormatter);

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional , Action =RouteParameter.Optional }

        );
    }
}

In Netbeans, it may be helpful to design a max heap size. Go to Run => Set Project Configuration => Customise. In the Run of its popped up window, go to VM Option, fill in -Xms2048m -Xmx2048m. It could solve heap size problem.

I achieve this in a view with a subview that is an UIImageView. The image the ImageView is pointing to is a gradient. Then I set a background color in the UIView, and I have a colored gradient view. Next I use the view as I need to and everything I draw will be under this gradient view. By adding a second view on top of the ImageView, you can have some options whether your drawing will be below or above the gradient...

Try this

$date = Carbon::parse(date_format($youttimestring,'d/m/Y H:i:s'));
echo $date;

I think it is enough:

list.Select(s => s.MyField).Distinct();

1. Reset or apply the scheme
2. Save
3. Restart Visual Studio

You could use an <a> tag with different styles:

a:link    { }
a:visited { }
a:hover   { }
a:active  { }

I'd recommend using that in conjunction with CSS sprites: https://css-tricks.com/css-sprites/

XML is not a format for storing images, neither binary data. I think it all depends on how you want to use those images. If you are in a web application and would want to read them from there and display them, I would store the URLs. If you need to send them to another web endpoint, I would serialize them, rather than persisting manually in XML. Please explain what is the scenario.

There is this extensions that adds an event listener to attribute changes.

Usage:

Bind attrchange handler function to selected elements

$(selector).attrchange({
    trackValues: true, /* Default to false, if set to true the event object is 
                updated with old and new value.*/
    callback: function (event) { 
        //event               - event object
        //event.attributeName - Name of the attribute modified
        //event.oldValue      - Previous value of the modified attribute
        //event.newValue      - New value of the modified attribute
        //Triggered when the selected elements attribute is added/updated/removed
    }        
});

I would like to put here a quote from the book "The Art of UNIX Programming":

Many people who regularly use both vi and Emacs tend to use them for different things, and find it valuable to know both.

In general, vi is best for small jobs – quick replies to mail, simple tweaks to system configuration, and the like. It is especially useful when you’re using a new system (or a remote one over a network) and don’t have your Emacs customization files handy.

Emacs comes into its own for extended editing sessions in which you have to handle complex tasks, modify multiple files, and use results from other programs during the session. For programmers using X on their console (which is typical on modern Unixes), it’s normal to start up Emacs shortly after login time in a large window and leave it running forever, possibly visiting dozens of files and even running programs in multiple Emacs subwindows.

What I really want to highlight here is the: «Many people find it valuable to know both.»

You can use bind method to attach function to several events. Just pass the event names and the handler function as in this code:

$('#foo').bind('mouseenter mouseleave', function() {
  $(this).toggleClass('entered');
});

Another option is to use chaining support of jquery api.

this works too.

df = NULL
for (k in 1:10)
    {
       x = 1
       y = 2
       z = 3
       df = rbind(df, data.frame(x,y,z))
     }

output will look like this

df #enter

x y z #col names
1 2 3

Support for multi-root workspaces is now enabled by default in the latest stable release [November 2017 release].

The File > Add Folder to Workspace command brings up an Open Folder dialog to select the new folder.

You can try this:

<?php 
    $feat_image = wp_get_attachment_url(get_post_thumbnail_id($post->ID)); 
    echo $feat_image; 
?>

I have found the answer by @Slauma here very useful for speeding things up. I used the same sort of pattern for both inserts and updates - and performance rocketed.

You can either go the LoadLibrary/GetProcAddress route (as Harper mentioned in his answer, here's link to the run-time dynamic linking MSDN sample again) or you can link your console application to the .lib produced from the DLL project and include the hea.h file with the declaration of your function (as described in the load-time dynamic linking MSDN sample)

In both cases, you need to make sure your DLL exports the function you want to call properly. The easiest way to do it is by using __declspec(dllexport) on the function declaration (as shown in the creating a simple dynamic-link library MSDN sample), though you can do it also through the corresponding .def file in your DLL project.

For more information on the topic of DLLs, you should browse through the MSDN About Dynamic-Link Libraries topic.

This may help shed a little light: (from page 11 of PDF32000.book)

PDF syntax is best understood by considering it as four parts, as shown in Figure 1:

• Objects. A PDF document is a data structure composed from a small set of basic types of data objects. Sub-clause 7.2, "Lexical Conventions," describes the character set used to write objects and other syntactic elements. Sub-clause 7.3, "Objects," describes the syntax and essential properties of the objects. Sub-clause 7.3.8, "Stream Objects," provides complete details of the most complex data type, the stream object.

• File structure. The PDF file structure determines how objects are stored in a PDF file, how they are accessed, and how they are updated. This structure is independent of the semantics of the objects. Sub- clause 7.5, "File Structure," describes the file structure. Sub-clause 7.6, "Encryption," describes a file-level mechanism for protecting a document’s contents from unauthorized access.

• Document structure. The PDF document structure specifies how the basic object types are used to represent components of a PDF document: pages, fonts, annotations, and so forth. Sub-clause 7.7, "Document Structure," describes the overall document structure; later clauses address the detailed semantics of the components.

• Content streams. A PDF content stream contains a sequence of instructions describing the appearance of a page or other graphical entity. These instructions, while also represented as objects, are conceptually distinct from the objects that represent the document structure and are described separately. Sub-clause 7.8, "Content Streams and Resources," discusses PDF content streams and their associated resources.

Looks like navigating a PDF file will require a little more than a passing effort.

        self.timer = Timer(fireAt: fire,
                           interval: deltaT,
                           target: self,
                           selector: #selector(timerCallBack(timer:)),
                           userInfo: ["custom":"data"],
                           repeats: true)

        RunLoop.main.add(self.timer!, forMode: RunLoopMode.commonModes)
        self.timer!.fire()
}

func timerCallBack(timer: Timer!){
        let info = timer.userInfo
        print(info)
    }

.img-responsive {
     margin: 0 auto;
 }

you can write like above code in your document so no need to add one another class in image tag.

fwrite($handle, "<br>"."\r\n");

Add this under

$password = $_POST['password'].PHP_EOL;

this. .

1. You can use a struct to read write into a file. You do not need to cast it as a `char*. Struct size will also be preserved. (This point is not closest to the topic but guess it: behaving on hard memory is often similar to RAM one.)

2. To move (to & from) a single string field you must use strncpy and a transient string buffer '\0' terminating. Somewhere you must remember the length of the record string field.

3. To move other fields you can use the dot notation, ex.: NodeB->one=intvar; floatvar2=(NodeA->insidebisnode_subvar).myfl;

   struct mynode {
       int one;
       int two;
       char txt3[3];
       struct{char txt2[6];}txt2fi;
       struct insidenode{
           char txt[8];
           long int myl;
           void * mypointer;
           size_t myst;
           long long myll;
            } insidenode_subvar;
       struct insidebisnode{
           float myfl;
            } insidebisnode_subvar;
   } mynode_subvar;
   
   typedef struct mynode* Node;
   
   ...(main)
   Node NodeA=malloc...
   Node NodeB=malloc...
   

4. You can embed each string into a structs that fit it, to evade point-2 and behave like Cobol: NodeB->txt2fi=NodeA->txt2fi ...but you will still need of a transient string plus one strncpy as mentioned at point-2 for scanf, printf otherwise an operator longer input (shorter), would have not be truncated (by spaces padded).

5. (NodeB->insidenode_subvar).mypointer=(NodeA->insidenode_subvar).mypointer will create a pointer alias.
6. NodeB.txt3=NodeA.txt3 causes the compiler to reject: error: incompatible types when assigning to type ‘char[3]’ from type ‘char *’

7. point-4 works only because NodeB->txt2fi & NodeA->txt2fi belong to the same typedef !!

   A correct and simple answer to this topic I found at In C, why can't I assign a string to a char array after it's declared? "Arrays (also of chars) are second-class citizens in C"!!!

Or you can decrement/increment a variable by the number of times you want to loop:

SETLOCAL ENABLEDELAYEDEXPANSION
SET counter=200
:Beginning
IF %counter% NEQ 0 (
echo %x
copy %x.txt z:\whatever\etc
SET /A counter=%counter%-1
GOTO Beginning
) ELSE (
ENDLOCAL
SET counter=
GOTO:eof

Obviously, using FOR /L is the highway and this is the backstreet that takes longer, but it gets to the same destination.

I have take the reference from here with changed column name.

You can't do that. If you use a redirect (or any other server technique) you will never send the actual page to the browser, only redirection pages.

You have to either use a meta tag or JavaScript to do this, so that you can reload the page after it has been displayed for a while:

ScriptManager.RegisterStartupScript(this, GetType(), "refresh", "window.setTimeout('window.location.reload(true);',5000);", true);

In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.

But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:

{ Id: 1, 
name:'john', 
phones:[{title:'home',number:111111,...},
        {title:'office',number:22222,...}]
}

sends

{ Id: 1, 
name:'john', 
phones:[object object]
phones:[object object]
}

Try this

Sub Sample()
    Dim test As Worksheet
    Sheets(1).Copy After:=Sheets(Sheets.Count)
    Set test = ActiveSheet
    test.Name = "copied sheet!"
End Sub

Since this is a pretty old question, and this method hasn't been added (aside from the system() call function) I guess it would be useful to include creating the shell script with the C binary itself. The shell code will be housed inside the file.c source file. Here is an example of code:

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

#define SHELLSCRIPT "\
#/bin/bash \n\
echo -e \"\" \n\
echo -e \"This is a test shell script inside C code!!\" \n\
read -p \"press <enter> to continue\" \n\
clear\
"

int main() {

system(SHELLSCRIPT);
return 0;
}

Basically, in a nutshell (pun intended), we are defining the script name, fleshing out the script, enclosing them in double quotes (while inserting proper escapes to ignore double quotes in the shell code), and then calling that script's name, which in this example is SHELLSCRIPT using the system() function in main().

JavaScript is, with a very few exceptions (XMLHttpRequest onreadystatechange handlers in some versions of Firefox) event-loop concurrent. So you needn't worry about locking in this case.

JavaScript has a concurrency model based on an "event loop". This model is quite different than the model in other languages like C or Java.

...

A JavaScript runtime contains a message queue, which is a list of messages to be processed. To each message is associated a function. When the stack is empty, a message is taken out of the queue and processed. The processing consists of calling the associated function (and thus creating an initial stack frame) The message processing ends when the stack becomes empty again.

...

Each message is processed completely before any other message is processed. This offers some nice properties when reasoning about your program, including the fact that whenever a function runs, it cannot be pre-empted and will run entirely before any other code runs (and can modify data the function manipulates). This differs from C, for instance, where if a function runs in a thread, it can be stopped at any point to run some other code in another thread.

A downside of this model is that if a message takes too long to complete, the web application is unable to process user interactions like click or scroll. The browser mitigates this with the "a script is taking too long to run" dialog. A good practice to follow is to make message processing short and if possible cut down one message into several messages.

On MaxOSX there may be perlcc. Type man perlcc. On my system (10.6.8) it's in /usr/bin. YMMV

None of this answers worked for me because I needed this to work under Linux using monodevelop. This works great for me:

Call this method passing it a unique ID

    public static void PreventMultipleInstance(string applicationId)
    {
        // Under Windows this is:
        //      C:\Users\SomeUser\AppData\Local\Temp\ 
        // Linux this is:
        //      /tmp/
        var temporaryDirectory = Path.GetTempPath();

        // Application ID (Make sure this guid is different accross your different applications!
        var applicationGuid = applicationId + ".process-lock";

        // file that will serve as our lock
        var fileFulePath = Path.Combine(temporaryDirectory, applicationGuid);

        try
        {
            // Prevents other processes from reading from or writing to this file
            var _InstanceLock = new FileStream(fileFulePath, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None);
            _InstanceLock.Lock(0, 0);
            MonoApp.Logger.LogToDisk(LogType.Notification, "04ZH-EQP0", "Aquired Lock", fileFulePath);

            // todo investigate why we need a reference to file stream. Without this GC releases the lock!
            System.Timers.Timer t = new System.Timers.Timer()
            {
                Interval = 500000,
                Enabled = true,
            };
            t.Elapsed += (a, b) =>
            {
                try
                {
                    _InstanceLock.Lock(0, 0);
                }
                catch
                {
                    MonoApp.Logger.Log(LogType.Error, "AOI7-QMCT", "Unable to lock file");
                }
            };
            t.Start();

        }
        catch
        {
            // Terminate application because another instance with this ID is running
            Environment.Exit(102534); 
        }
    }         

Any algorithm implemented using recursion can also be implemented using iteration.

Why not to use recursion

1. It is usually slower due to the overhead of maintaining the stack.
2. It usually uses more memory for the stack.

Why to use recursion

1. Recursion adds clarity and (sometimes) reduces the time needed to write and debug code (but doesn't necessarily reduce space requirements or speed of execution).
2. Reduces time complexity.
3. Performs better in solving problems based on tree structures.

For example, the Tower of Hanoi problem is more easily solved using recursion as opposed to iteration.

sys .argv will display the command line args passed when running a script or you can say sys.argv will store the command line arguments passed in python while running from terminal.

Just try this:

import sys
print sys.argv

argv stores all the arguments passed in a python list. The above will print all arguments passed will running the script.

Now try this running your filename.py like this:

python filename.py example example1

this will print 3 arguments in a list.

sys.argv[0] #is the first argument passed, which is basically the filename. 

Similarly, argv1 is the first argument passed, in this case 'example'

A similar question has been asked already here btw. Hope this helps!

If you want to retrieve the display text of the item, use the GetItemText method:

string text = listBox1.GetItemText(listBox1.SelectedItem);

Enter the formula =ROW() into any cell and that cell will show the row number as its value.

If you want 1001, 1002 etc just enter =1000+ROW()

This linq query Should work for you. It will get all the posts that have post meta.

var query = database.Posts.Join(database.Post_Metas,
                                post => post.postId, // Primary Key
                                meta => meat.postId, // Foreign Key
                                (post, meta) => new { Post = post, Meta = meta });

Equivalent SQL Query

Select * FROM Posts P
INNER JOIN Post_Metas pm ON pm.postId=p.postId

Thanks for the answers above, that helped me a lot :-) But for those (like me) forced to still support Android 1.5 we can use java reflection for backward compatible:

Configuration conf = getResources().getConfiguration();
int screenLayout = 1; // application default behavior
try {
    Field field = conf.getClass().getDeclaredField("screenLayout");
    screenLayout = field.getInt(conf);
} catch (Exception e) {
    // NoSuchFieldException or related stuff
}
// Configuration.SCREENLAYOUT_SIZE_MASK == 15
int screenType = screenLayout & 15;
// Configuration.SCREENLAYOUT_SIZE_SMALL == 1
// Configuration.SCREENLAYOUT_SIZE_NORMAL == 2
// Configuration.SCREENLAYOUT_SIZE_LARGE == 3
// Configuration.SCREENLAYOUT_SIZE_XLARGE == 4
if (screenType == 1) {
    ...
} else if (screenType == 2) {
    ...
} else if (screenType == 3) {
    ...
} else if (screenType == 4) {
    ...
} else { // undefined
    ...
}

To add new ViewController once you have have an existing ViewController, follow below step:

1. Click on background of Main.storyboard.

2. Search and select ViewController from object library at the utility window.

3. Drag and drop it in background to create a new ViewController.

This version allows you to have more than one case y or Y, n or N

1. Optionally: Repeat the question until an approve question is provided

2. Optionally: Ignore any other answer

3. Optionally: Exit the terminal if you want

   confirm() {
       echo -n "Continue? y or n? "
       read REPLY
       case $REPLY in
       [Yy]) echo 'yup y' ;; # you can change what you do here for instance
       [Nn]) break ;;        # exit case statement gracefully
       # Here are a few optional options to choose between
       # Any other answer:
   
       # 1. Repeat the question
       *) confirm ;;
   
       # 2. ignore
       # *) ;;
   
       # 3. Exit terminal
       # *) exit ;;
   
       esac
       # REPLY=''
   }
   

Notice this too: On the last line of this function clear the REPLY variable. Otherwise if you echo $REPLY you will see it is still set until you open or close your terminal or set it again.

this is how you do it with ActionLIstener

Functions are first-class objects in Swift. So if you don't want to use a closure, you can also just define a function with the appropriate signature and then pass it as the handler argument. Observe:

func someHandler(alert: UIAlertAction!) {
    // Do something...
}

alert.addAction(UIAlertAction(title: "Okay",
                              style: UIAlertActionStyle.Default,
                              handler: someHandler))

I use DelayedProgressDialog from https://github.com/Q115/DelayedProgressDialog It does the same as ProgressDialog with the added benefit of a delay if necessary.

Using it is similar to ProgressDialog before Android O:

DelayedProgressDialog progressDialog = new DelayedProgressDialog();
progressDialog.show(getSupportFragmentManager(), "tag");

It's just docker pull busybox, are you using an up to date version of the docker client. I think they stopped supporting clients lower than 1.5.

Incidentally that curl works for me:

$ curl -k https://registry.hub.docker.com/v1/repositories/busybox/tags
[{"layer": "fc0db02f", "name": "latest"}, {"layer": "fc0db02f", "name": "1"}, {"layer": "a6dbc8d6", "name": "1-ubuntu"}, {"layer": "a6dbc8d6", "name": "1.21-ubuntu"}, {"layer": "a6dbc8d6", "name": "1.21.0-ubuntu"}, {"layer": "d7057cb0", "name": "1.23"}, {"layer": "d7057cb0", "name": "1.23.2"}, {"layer": "fc0db02f", "name": "1.24"}, {"layer": "3d5bcd78", "name": "1.24.0"}, {"layer": "fc0db02f", "name": "1.24.1"}, {"layer": "1c677c87", "name": "buildroot-2013.08.1"}, {"layer": "0f864637", "name": "buildroot-2014.02"}, {"layer": "a6dbc8d6", "name": "ubuntu"}, {"layer": "ff8f955d", "name": "ubuntu-12.04"}, {"layer": "633fcd11", "name": "ubuntu-14.04"}]

Interesting enough if you sniff the headers you get a HTTP 405 (Method not allowed). I think this might be to do with the fact that Docker have deprecated their Registry API.

I did a quick solution because I was short of time and it worked ok. Although I think the better option is use an Exception Filter, maybe my solution can help in the case that a simple solution is needed.

I did the following. In the controller method I returned a JsonResult with a property "Success" inside the Data:

    [HttpPut]
    public JsonResult UpdateEmployeeConfig(EmployeConfig employeToSave) 
    {
        if (!ModelState.IsValid)
        {
            return new JsonResult
            {
                Data = new { ErrorMessage = "Model is not valid", Success = false },
                ContentEncoding = System.Text.Encoding.UTF8,
                JsonRequestBehavior = JsonRequestBehavior.DenyGet
            };
        }
        try
        {
            MyDbContext db = new MyDbContext();

            db.Entry(employeToSave).State = EntityState.Modified;
            db.SaveChanges();

            DTO.EmployeConfig user = (DTO.EmployeConfig)Session["EmployeLoggin"];

            if (employeToSave.Id == user.Id)
            {
                user.Company = employeToSave.Company;
                user.Language = employeToSave.Language;
                user.Money = employeToSave.Money;
                user.CostCenter = employeToSave.CostCenter;

                Session["EmployeLoggin"] = user;
            }
        }
        catch (Exception ex) 
        {
            return new JsonResult
            {
                Data = new { ErrorMessage = ex.Message, Success = false },
                ContentEncoding = System.Text.Encoding.UTF8,
                JsonRequestBehavior = JsonRequestBehavior.DenyGet
            };
        }

        return new JsonResult() { Data = new { Success = true }, };
    }

Later in the ajax call I just asked for this property to know if I had an exception:

$.ajax({
    url: 'UpdateEmployeeConfig',
    type: 'PUT',
    data: JSON.stringify(EmployeConfig),
    contentType: "application/json;charset=utf-8",
    success: function (data) {
        if (data.Success) {
            //This is for the example. Please do something prettier for the user, :)
            alert('All was really ok');                                           
        }
        else {
            alert('Oups.. we had errors: ' + data.ErrorMessage);
        }
    },
    error: function (request, status, error) {
       alert('oh, errors here. The call to the server is not working.')
    }
});

Hope this helps. Happy code! :P

As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:

<?php

    $world = _("World");

    $str = <<<EOF
    <p>Hello</p>
    <p>$world</p>
EOF;
    echo $str;
?>

a workaround idea that comes to mind is building a class with a magic getter method.

You would declare a class like this:

class Translator
{
 public function __get($name) {
  return _($name); // Does the gettext lookup
  }
 }

Initialize an object of the class at some point:

  $translate = new Translator();

You can then use the following syntax to do a gettext lookup inside a HEREDOC block:

    $str = <<<EOF
    <p>Hello</p>
    <p>{$translate->World}</p>
EOF;
    echo $str;
?>

$translate->World will automatically be translated to the gettext lookup thanks to the magic getter method.

To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!, you will have to use the following notation:

 $translate->{"Hello World!!!!!!"}

This is all untested but should work.

Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.

As I did not had the mentioned option in my VS which is Visual Studio Enterprise 2017, I had to look for some other option.

Here is it what I've found:

Go to Tools -> Options -> Debugging tab(General) and uncheck "Enable JavaScript debugging for Asp.Net(Chrome and IE).

myarray = "abc";

...is the assignation of a pointer on "abc" to the pointer myarray.

This is NOT filling the myarray buffer with "abc".

If you want to fill the myarray buffer manually, without strcpy(), you can use:

myarray[0] = 'a', myarray[1] = 'b', myarray[2] = 'c', myarray[3] = 0;

or

char *ptr = myarray;
*ptr++ = 'a', *ptr++ = 'b', *ptr++ = 'c', *ptr = 0;

Your question is about the difference between a pointer and a buffer (an array). I hope you now understand how C addresses each kind.

I think you need something like this: http://jsfiddle.net/BeenYoung/BXaqW/3/

$(document).ready(function() {
  $("ul.opMenu li").each(function(){
      $(this).click(function(){
            if($(this).hasClass('opened')==false){          
                $('.opMenu').find('.opened').removeClass('opened').find('ul').slideUp();
                $(this).addClass('opened'); 
                $(this).find("ul").slideDown();
            }else{
                $(this).removeClass('opened'); 
                $(this).find("ul").slideUp();               
            }
      });
  });    
});

I hope it useful for you!

Just to showcase my skills too (lol), above function can written even without having named arguments as below:

ES5 and above

function foo() {
    a = typeof arguments[0] !== 'undefined' ? a : 42;
    b = typeof arguments[1] !== 'undefined' ? b : 'default_b';
    ...
}

ES6 and above

function foo(...rest) {
    a = typeof rest[0] !== 'undefined' ? a : 42;
    b = typeof rest[1] !== 'undefined' ? b : 'default_b';
    ...
}

The command clause does work as @Karthik says above.

As a simple example, the following service will have a -inMemory added to its ENTRYPOINT when docker-compose up is run.

version: '2'
services:
  local-dynamo:
    build: local-dynamo
    image: spud/dynamo
    command: -inMemory

Here the value adder is use of ampersands to batch commands and correct format for change drive with cd.

}

In my case I was using a JDK 8 client and the server was using insecure old ciphers. The server is Apache and I added this line to the Apache config:

SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:!MEDIUM:!LOW:!SSLv2:!EXPORT

You should use a tool like this to verify your SSL configuration is currently secure: https://www.ssllabs.com/ssltest/analyze.html

You can set a property on the form to do this for you if you have a button on the form that closes the form already.

Set the CancelButton property of the form to that button.

Gets or sets the button control that is clicked when the user presses the Esc key.

If you don't have a cancel button then you'll need to add a KeyDown handler and check for the Esc key in that:

private void Form_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Escape)
    {
        this.Close();
    }
}

You will also have to set the KeyPreview property to true.

Gets or sets a value indicating whether the form will receive key events before the event is passed to the control that has focus.

However, as Gargo points out in his answer this will mean that pressing Esc to abort an edit on a control in the dialog will also have the effect of closing the dialog. To avoid that override the ProcessDialogKey method as follows:

protected override bool ProcessDialogKey(Keys keyData)
{
    if (Form.ModifierKeys == Keys.None && keyData == Keys.Escape)
    {
        this.Close();
        return true;
    }
    return base.ProcessDialogKey(keyData);
}

Because the join() method is in the string class, instead of the list class?

I agree it looks funny.

See http://www.faqs.org/docs/diveintopython/odbchelper_join.html:

Historical note. When I first learned Python, I expected join to be a method of a list, which would take the delimiter as an argument. Lots of people feel the same way, and there’s a story behind the join method. Prior to Python 1.6, strings didn’t have all these useful methods. There was a separate string module which contained all the string functions; each function took a string as its first argument. The functions were deemed important enough to put onto the strings themselves, which made sense for functions like lower, upper, and split. But many hard-core Python programmers objected to the new join method, arguing that it should be a method of the list instead, or that it shouldn’t move at all but simply stay a part of the old string module (which still has lots of useful stuff in it). I use the new join method exclusively, but you will see code written either way, and if it really bothers you, you can use the old string.join function instead.

--- Mark Pilgrim, Dive into Python

This example might help you. by using simple casting you can get code behind urdu character.

string str = "?????";
        char ch = ' ';
        int number = 0;
        for (int i = 0; i < str.Length; i++)
        {
            ch = str[i];
            number = (int)ch;
            Console.WriteLine(number);
        }

In NodeJS, Buffer.byteLength is a method specifically for this purpose:

let strLengthInBytes = Buffer.byteLength(str); // str is UTF-8

Note that by default the method assumes the string is in UTF-8 encoding. If a different encoding is required, pass it as the second argument.

To just return a list containing the most common words:

from collections import Counter
words=["i", "love", "you", "i", "you", "a", "are", "you", "you", "fine", "green"]
most_common_words= [word for word, word_count in Counter(words).most_common(3)]
print most_common_words

this prints:

['you', 'i', 'a']

the 3 in "most_common(3)", specifies the number of items to print. Counter(words).most_common() returns a a list of tuples with each tuple having the word as the first member and the frequency as the second member.The tuples are ordered by the frequency of the word.

`most_common = [item for item in Counter(words).most_common()]
print(str(most_common))
[('you', 4), ('i', 2), ('a', 1), ('are', 1), ('green', 1), ('love',1), ('fine', 1)]`

"the word for word, word_counter in", extracts only the first member of the tuple.

Here's a map command to select all to the clipboard using CTRL+a:

"
" select all with control-a
"
nnoremap <C-a> ggmqvG"+y'q

Add it to your .vimrc and you're good to go...

try

.something { 
    background: url(images/bg.jpg) no-repeat center center fixed; 
    width: 100%;
    height: 100%;
    position: fixed;
    top: 0;
    left: 0;
    z-index: -100;  
}

Here's yet another option to add to the mix:

$ du -b file.txt

That is: estimate file space usage of file.txt in bytes.

I created this code for creating a nice, readable csv files:

var objectToCSVRow = function(dataObject) {
    var dataArray = new Array;
    for (var o in dataObject) {
        var innerValue = dataObject[o]===null?'':dataObject[o].toString();
        var result = innerValue.replace(/"/g, '""');
        result = '"' + result + '"';
        dataArray.push(result);
    }
    return dataArray.join(' ') + '\r\n';
}

var exportToCSV = function(arrayOfObjects) {

    if (!arrayOfObjects.length) {
        return;
    }

    var csvContent = "data:text/csv;charset=utf-8,";

    // headers
    csvContent += objectToCSVRow(Object.keys(arrayOfObjects[0]));

    arrayOfObjects.forEach(function(item){
        csvContent += objectToCSVRow(item);
    }); 

    var encodedUri = encodeURI(csvContent);
    var link = document.createElement("a");
    link.setAttribute("href", encodedUri);
    link.setAttribute("download", "customers.csv");
    document.body.appendChild(link); // Required for FF
    link.click();
    document.body.removeChild(link); 
}

In your case, since you use arrays in array instead of objects in array, You will skip the header part, but you could add the column names yourself by putting this instead of that part:

// headers
csvContent += '"Column name 1" "Column name 2" "Column name 3"\n';

The secret is that a space separates the columns in the csv file, and we put the column values in the double quotes to allow spaces, and escape any double quotes in the values themselves.

Also note that I replace null values with empty string, because that suited my needs, but you can change that and replace it with anything you like.

Use DataFrame.to_excel from pandas. Pandas allows you to represent your data in functionally rich datastructures and will let you read in excel files as well.

You will first have to convert your data into a DataFrame and then save it into an excel file like so:

In [1]: from pandas import DataFrame
In [2]: l1 = [1,2,3,4]
In [3]: l2 = [1,2,3,4]
In [3]: df = DataFrame({'Stimulus Time': l1, 'Reaction Time': l2})
In [4]: df
Out[4]: 
   Reaction Time  Stimulus Time
0              1              1
1              2              2
2              3              3
3              4              4

In [5]: df.to_excel('test.xlsx', sheet_name='sheet1', index=False)

and the excel file that comes out looks like this:

Note that both lists need to be of equal length else pandas will complain. To solve this, replace all missing values with None.

Used to face the same problem. The reason was in incorrect context passing to AlertDialog.Builder(here). use like AlertDialog.Builder(Homeactivity.this)

1. If you are able to see "mysql stopped" when you run below command;

   brew services list
   

2. and if you are able to start mysql with below command;

   mysql server start
   

this means; mysql is able to start manually, but it doesn't start automatically when the operating system is started. Adding mysql to services will fix this problem. To do so, you can run below command;

brew services start mysql

After that, you may restart your operating system and try connecting to mysql to see if it started automatically. I did the same and stop receiving below error;

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

I hope this helps.

To get the definition of the SQL codes, the easiest way is to use db2 cli!

at the unix or dos command prompt, just type

db2 "? SQL302"

this will give you the required explanation of the particular SQL code that you normally see in the java exception or your db2 sql output :)

hope this helped.

You need this include:

#include <sstream>

The accepted answer does not work in Jupyter (at least when using some libraries).

The Javascript solutions here only hide warnings that are already showing but not warnings that would be shown in the future.

To hide/unhide warnings in Jupyter and JupyterLab I wrote the following script that essentially toggles css to hide/unhide warnings.

%%javascript
(function(on) {
const e=$( "<a>Setup failed</a>" );
const ns="js_jupyter_suppress_warnings";
var cssrules=$("#"+ns);
if(!cssrules.length) cssrules = $("<style id='"+ns+"' type='text/css'>div.output_stderr { } </style>").appendTo("head");
e.click(function() {
    var s='Showing';  
    cssrules.empty()
    if(on) {
        s='Hiding';
        cssrules.append("div.output_stderr, div[data-mime-type*='.stderr'] { display:none; }");
    }
    e.text(s+' warnings (click to toggle)');
    on=!on;
}).click();
$(element).append(e);
})(true);

There is another possibility - standalone VALUES():

VALUES ('Hello World');

Output:

column1
Hello World

It is useful when you need to specify multiple values in compact way:

VALUES (1, 'a'), (2, 'b'), (3, 'c');

Output:

column1     column2
      1     a
      2     b
      3     c

Adding to Tim's answer:

  #search:placeholder-shown {
     // show background image, I like svg 
     // when using svg, do not use HEX for colour; you can use rbg/a instead
     // also notice the single quotes
     background-image url('data:image/svg+xml; utf8, <svg>... <g fill="grey"...</svg>')
     // other background props
   }

   #search:not(:placeholder-shown) { background-image: none;}

<a href="javaScript:{openPopUp();}"></a>
<form action="actionName">
<div id="divId" style="display:none;">
UsreName:<input type="text" name="userName"/>
</div>
</form>

function openPopUp()
{
  $('#divId').css('display','block');
$('#divId').dialog();
}

While this doesn't answer the question of how to do this via the viewmodel, this does show how to do it using only XAML + the blend SDK.

I chose to download and use two files from the Blend SDK, both of which you can as a package from Microsoft through NuGet. The files are:

System.Windows.Interactivity.dll and Microsoft.Expression.Interactions.dll

Microsoft.Expression.Interactions.dll gives you nice capabilities such as the ability to set property or invoke a method on your viewmodel or other target and has other widgets inside as well.

Some XAML:

<Window x:Class="Blah.Blah.MyWindow"
    ...
    xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
    xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"
  ...>
 <StackPanel>
    <Button x:Name="OKButton" Content="OK">
       <i:Interaction.Triggers>
          <i:EventTrigger EventName="Click">
             <ei:ChangePropertyAction
                      TargetObject="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"
                      PropertyName="DialogResult"
                      Value="True"
                      IsEnabled="{Binding SomeBoolOnTheVM}" />                                
          </i:EventTrigger>
    </Button>
    <Button x:Name="CancelButton" Content="Cancel">
       <i:Interaction.Triggers>
          <i:EventTrigger EventName="Click">
             <ei:ChangePropertyAction
                      TargetObject="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"
                      PropertyName="DialogResult"
                      Value="False" />                                
          </i:EventTrigger>
    </Button>

    <Button x:Name="CloseButton" Content="Close">
       <i:Interaction.Triggers>
                <i:EventTrigger EventName="Click">
                    <!-- method being invoked should be void w/ no args -->
                    <ei:CallMethodAction
                        TargetObject="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"
                        MethodName="Close" />
                </i:EventTrigger>
            </i:Interaction.Triggers>
    </Button>
 <StackPanel>
</Window>

Note that if you're just going for simple OK/Cancel behavior, you can get away w/ using the IsDefault and IsCancel properties as long as the window is shown w/ Window.ShowDialog().
I personally had problems w/ a button that had the IsDefault property set to true, but it was hidden when the page is loaded. It didn't seem to want to play nicely after it was shown, so I just am setting the Window.DialogResult property as shown above instead and it works for me.

I use inf/-inf as initial values to find minimum/maximum value of a measurement. Lets say that you measure temperature with a sensor and you want to keep track of minimum/maximum temperature. The sensor might provide a valid temperature or might be broken. Pseudocode:

# initial value of the temperature
t = float('nan')          
# initial value of minimum temperature, so any measured temp. will be smaller
t_min = float('inf')      
# initial value of maximum temperature, so any measured temp. will be bigger
t_max = float('-inf')     
while True:
    # measure temperature, if sensor is broken t is not changed
    t = measure()     
    # find new minimum temperature
    t_min = min(t_min, t) 
    # find new maximum temperature
    t_max = max(t_max, t) 

The above code works because inf/-inf/nan are valid for min/max operation, so there is no need to deal with exceptions.

for finding out that user is new or old , Get user IP .

create a table for IPs and their visits timestamp .

check IF IP does not exists OR time()-saved_timestamp > 60*60*24 (for 1 day) ,edit the IP's timestamp to time() (means now) and increase your view one .

else , do nothing .

FYI : user IP is stored in $_SERVER['REMOTE_ADDR'] variable

        $out[$index] = ( is_object ( $node ) ) ? xml2array ( $node ) : $node;

    return $out;
}

It could help you. However, if you convert XML to an array you will loose all attributes that might be present, so you cannot go back to XML and get the same XML.

Be carefull that the page does not contain any empty component which has "required" attribute as "true" before your selectOneMenu component running.
If you use a component such as

<p:inputText label="Nm:" id="id_name" value="#{ myHelper.name}" required="true"/>

then,

<p:selectOneMenu .....></p:selectOneMenu>

and forget to fill the required component, ajax listener of selectoneMenu cannot be executed.

NoClassDefFoundError can also occur when a static initializer tries to load a resource bundle that is not available in runtime, for example a properties file that the affected class tries to load from the META-INF directory, but isn’t there. If you don’t catch NoClassDefFoundError, sometimes you won’t be able to see the full stack trace; to overcome this you can temporarily use a catch clause for Throwable:

try {
    // Statement(s) that cause(s) the affected class to be loaded
} catch (Throwable t) {
    Logger.getLogger("<logger-name>").info("Loading my class went wrong", t);
}

If Ruby is installed, then

ruby yourfile.rb

where yourfile.rb is the file containing the ruby code.

Or

irb

to start the interactive Ruby environment, where you can type lines of code and see the results immediately.

Is this a broader naming convention in any real sense? I'm more on the C++ side, and not really up on Java and descendants. How many language communities use the I convention?

If you have a language-independent shop standard naming convention here, use it. If not, go with the language naming convention.

Try the following commands:

$ sudo apt-get install nodejs
$ sudo apt-get install aptitude
$ sudo aptitude install npm

This line:

private dynamic defaultReminder = 
                          reminder.TimeSpanText[TimeSpan.FromMinutes(15)];

You cannot use an instance variable to initialize another instance variable. Why? Because the compiler can rearrange these - there is no guarantee that reminder will be initialized before defaultReminder, so the above line might throw a NullReferenceException.

Instead, just use:

private dynamic defaultReminder = TimeSpan.FromMinutes(15);

Alternatively, set up the value in the constructor:

private dynamic defaultReminder;

public Reminders()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)]; 
}

There are more details about this compiler error on MSDN - Compiler Error CS0236.

I solved this with one code line, as follow: In file index.php, at your template root, after this code line:

defined( '_JEXEC' ) or die( 'Restricted access' );

paste this line: ini_set ('display_errors', 'Off');

Don't worry, be happy...

Your idea with the SequenceGenerator fake entity is good.

@Id
@GenericGenerator(name = "my_seq", strategy = "sequence", parameters = {
        @org.hibernate.annotations.Parameter(name = "sequence_name", value = "MY_CUSTOM_NAMED_SQN"),
})
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "my_seq")

It is important to use the parameter with the key name "sequence_name". Run a debugging session on the hibernate class SequenceStyleGenerator, the configure(...) method at the line final QualifiedName sequenceName = determineSequenceName( params, dialect, jdbcEnvironment ); to see more details about how the sequence name is computed by Hibernate. There are some defaults in there you could also use.

After the fake entity, I created a CrudRepository:

public interface SequenceRepository extends CrudRepository<SequenceGenerator, Long> {}

In the Junit, I call the save method of the SequenceRepository.

SequenceGenerator sequenceObject = new SequenceGenerator(); SequenceGenerator result = sequenceRepository.save(sequenceObject);

If there is a better way to do this (maybe support for a generator on any type of field instead of just Id), I would be more than happy to use it instead of this "trick".

Just use NVM(Node Version Manager) - https://github.com/creationix/nvm

It has become the standard for managing Node.js.

When you need a new version:

nvm install NEW_VER
nvm use XXX

If something goes wrong you can always go back with

nvm use OLD_VER

Actually, em.flush(), do more than just sends the cached SQL commands. It tries to synchronize the persistence context to the underlying database. It can cause a lot of time consumption on your processes if your cache contains collections to be synchronized.

Caution on using it.

Here is the complete solution

html code,

create the text anf file upload fields as shown below

    <div class="form-group">
        <div>
            <label for="usr">User Name:</label>
            <input type="text" id="usr" ng-model="model.username">
        </div>
        <div>
            <label for="pwd">Password:</label>
            <input type="password" id="pwd" ng-model="model.password">
        </div><hr>
        <div>
            <div class="col-lg-6">
                <input type="file" file-model="model.somefile"/>
            </div>


        </div>
        <div>
            <label for="dob">Dob:</label>
            <input type="date" id="dob" ng-model="model.dob">
        </div>
        <div>
            <label for="email">Email:</label>
            <input type="email"id="email" ng-model="model.email">
        </div>


        <button type="submit" ng-click="saveData(model)" >Submit</button>

directive code

create a filemodel directive to parse file

.directive('fileModel', ['$parse', function ($parse) {
return {
    restrict: 'A',
    link: function(scope, element, attrs) {
        var model = $parse(attrs.fileModel);
        var modelSetter = model.assign;

        element.bind('change', function(){
            scope.$apply(function(){
                modelSetter(scope, element[0].files[0]);
            });
        });
    }
};}]);

Service code

append the file and fields to form data and do $http.post as shown below remember to keep 'Content-Type': undefined

 .service('fileUploadService', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, username, password, dob, email, uploadUrl){
        var myFormData = new FormData();

        myFormData.append('file', file);
        myFormData.append('username', username);
        myFormData.append('password', password);
        myFormData.append('dob', dob);
        myFormData.append('email', email);


        $http.post(uploadUrl, myFormData, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
            .success(function(){

            })
            .error(function(){
            });
    }
}]);

In controller

Now in controller call the service by sending required data to be appended in parameters,

$scope.saveData  = function(model){
    var file = model.myFile;
    var uploadUrl = "/api/createUsers";
    fileUpload.uploadFileToUrl(file, model.username, model.password, model.dob, model.email, uploadUrl);
};

Because Java bytecode does not retain the names of method or constructor arguments.

You can also set the postBuffer globally, which might be necessary, if you haven't checkout out the repository yet!

git config http.postBuffer 524288000

u want select all data from database then u can try this:-

dbclassDataContext dc= new dbclassDataContext()
List<tableName> ObjectName= dc.tableName.ToList();

otherwise You can try this:-

var Registration = from reg in dcdc.GetTable<registration>() select reg;

and method Syntex :-

 var Registration = dc.registration.Select(reg => reg); 

I had this issue when my main project was in the same folder as the solution, then I had a separate project in the same solution located in a sub folder, and that separate project used the main project as a reference. This caused the main project to detect the sub folder bin & obj folders which created duplicate references.

sc delete "service name"

will delete a service. I find that the sc utility is much easier to locate than digging around for installutil. Remember to stop the service if you have not already.

For me its now :

docker restart $(docker ps -a -q)

You can, but be aware of the return types with jQuery functions. jQuery won't always use the exact same JavaScript object type, although generally they will return subclasses of what you would expect to be returned from a similar JavaScript function.

If anybody comes here because they are looking to echo a blank line from a MINGW make makefile, I used

@cmd /c echo.

simply using echo. causes the dreaded process_begin: CreateProcess(NULL, echo., ...) failed. error message.

I hope this helps at least one other person out there :)

When you find it necessary to update a primary key value as well as all matching foreign keys, then the entire design needs to be fixed.

It is tricky to cascade all the necessary foreign keys changes. It is a best practice to never update the primary key, and if you find it necessary, you should use a Surrogate Primary Key, which is a key not derived from application data. As a result its value is unrelated to the business logic and never needs to change (and should be invisible to the end user). You can then update and display some other column.

for example:

BadUserTable
UserID     varchar(20) primary key --user last name
other columns...

when you create many tables that have a FK to UserID, to track everything that the user has worked on, but that user then gets married and wants a ID to match their new last name, you are out of luck.

GoodUserTable
UserID    int identity(1,1) primary key
UserLogin varchar(20) 
other columns....

you now FK the Surrogate Primary Key to all the other tables, and display UserLogin when necessary, allow them to login using that value, and when they need to change it, you change it in one column of one row only.

Remove column constraint: not null to null

ALTER TABLE test ALTER COLUMN column_01 DROP NOT NULL;

For Changing Year list item text color (SPECIFIC FOR ANDROID 5.0)

Just set certain text color in your date picker dialog style. For some reason setting flag yearListItemTextAppearance doesn't reflect any change on year list.

<item name="android:textColor">@android:color/black</item>

You should use return as in:

function refreshGrid(entity) {
  var store = window.localStorage;
  var partitionKey;
  if (exit) {
    return;
  }

In gameprofile.html please change the tag {% endblock content %} to {% endblock %} then it works otherwise django will not load the endblock and give error.

You could try:

$('input.class').removeAttr('value');
$('#inputID').removeAttr('value');

This is the best way i have created so far.

var fs = require('fs'),
    includedFiles_ = {};

global.include = function (fileName) {
  var sys = require('sys');
  sys.puts('Loading file: ' + fileName);
  var ev = require(fileName);
  for (var prop in ev) {
    global[prop] = ev[prop];
  }
  includedFiles_[fileName] = true;
};

global.includeOnce = function (fileName) {
  if (!includedFiles_[fileName]) {
    include(fileName);
  }
};

global.includeFolderOnce = function (folder) {
  var file, fileName,
      sys = require('sys'),
      files = fs.readdirSync(folder);

  var getFileName = function(str) {
        var splited = str.split('.');
        splited.pop();
        return splited.join('.');
      },
      getExtension = function(str) {
        var splited = str.split('.');
        return splited[splited.length - 1];
      };

  for (var i = 0; i < files.length; i++) {
    file = files[i];
    if (getExtension(file) === 'js') {
      fileName = getFileName(file);
      try {
        includeOnce(folder + '/' + file);
      } catch (err) {
        // if (ext.vars) {
        //   console.log(ext.vars.dump(err));
        // } else {
        sys.puts(err);
        // }
      }
    }
  }
};

includeFolderOnce('./extensions');
includeOnce('./bin/Lara.js');

var lara = new Lara();

You still need to inform what you want to export

includeOnce('./bin/WebServer.js');

function Lara() {
  this.webServer = new WebServer();
  this.webServer.start();
}

Lara.prototype.webServer = null;

module.exports.Lara = Lara;

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

Change table_name and field to match your table name and field in question:

UPDATE table_name SET field = REPLACE(field, 'foo', 'bar') WHERE INSTR(field, 'foo') > 0;

• REPLACE (string functions)
• INSTR (string functions)

you can use something like this :

string [] filePaths = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);

instead of using "." you can type the name of the file or just the type like "*.txt" also SearchOption.AllDirectories is to search in all subfolders you can change that if you only want one level more about how to use it on here

I know this question is a bit old but i would suggest to use some cachebraking hash in the url of the javascript. This works perfectly in production as well as during development because you can have both infinite cache times and intant updates when changes occur.

Lets assume you have a javascript file /js/script.min.js, but in the referencing html/php file you do not use the actual path but:

<script src="/js/script.<?php echo md5(filemtime('/js/script.min.js')); ?>.min.js"></script>

So everytime the file is changed, the browser gets a different url, which in turn means it cannot be cached, be it locally or on any proxy inbetween.

To make this work you need nginx to rewrite any request to /js/script.[0-9a-f]{32}.min.js to the original filename. In my case i use the following directive (for css also):

location ~* \.(css|js)$ {
                expires max;
                add_header Pragma public;
                etag off;
                add_header Cache-Control "public";
                add_header Last-Modified "";
                rewrite  "^/(.*)\/(style|script)\.min\.([\d\w]{32})\.(js|css)$" /$1/$2.min.$4 break;
        }

I would guess that the filemtime call does not even require disk access on the server as it should be in linux's file cache. If you have doubts or static html files you can also use a fixed random value (or incremental or content hash) that is updated when your javascript / css preprocessor has finished or let one of your git hooks change it.

In theory you could also use a cachebreaker as a dummy parameter (like /js/script.min.js?cachebreak=0123456789abcfef), but then the file is not cached at least by some proxies because of the "?".

true and false are not meant to be strings in this context.

You want the literal true and false Boolean values.

startButton.disabled = true;

startButton.disabled = false;

The reason it sort of works (disables the element) is because a non empty string is truthy. So assigning 'false' to the disabled property has the same effect of setting it to true.

Building on @shabunc's answer, this would allow enforcing either the key or the value — or both — to be anything you want to enforce.

type IdentifierKeys = 'my.valid.key.1' | 'my.valid.key.2';
type IdentifierValues = 'my.valid.value.1' | 'my.valid.value.2';

let stuff = new Map<IdentifierKeys, IdentifierValues>();

Should also work using enum instead of a type definition.

Use sort() method to sort the list as below:

List list = new ArrayList();

//add elements to the list

Comparator comparator = new SomeComparator();

Collections.sort(list, comparator);

For reference see the link: http://tutorials.jenkov.com/java-collections/sorting.html

I use both conventions:

If the interface is a specific instance of a a well known pattern (e.g. Service, DAO), then it may not need an "I" (e.g UserService, AuditService, UserDao) all work fine without the "I", because the post-fix determines the meta pattern.

But, if you have something one-off or two-off (usually for a callback pattern), then it helps to distinguish it from a class (e.g. IAsynchCallbackHandler, IUpdateListener, IComputeDrone). These are special purpose interfaces designed for internal use, occasionally the IInterface calls out attention to the fact that an operand is actually an interface, so at first glance it is immediately clear.

In other cases you can use the I to avoid colliding with other commonly known concrete classes (ISubject, IPrincipal vs Subject or Principal).

You can implement a SoapExtension that logs the full request and response to a log file. You can then enable the SoapExtension in the web.config, which makes it easy to turn on/off for debugging purposes. Here is an example that I have found and modified for my own use, in my case the logging was done by log4net but you can replace the log methods with your own.

public class SoapLoggerExtension : SoapExtension
{
    private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
    private Stream oldStream;
    private Stream newStream;

    {
        return null;
    }

        return null;
    }

    {

    }

    public override System.IO.Stream ChainStream(System.IO.Stream stream)
    {
        oldStream = stream;
        newStream = new MemoryStream();
        return newStream;
    }

    public override void ProcessMessage(SoapMessage message)
    {

        switch (message.Stage)
        {
            case SoapMessageStage.BeforeSerialize:
                break;
            case SoapMessageStage.AfterSerialize:
                Log(message, "AfterSerialize");
                    CopyStream(newStream, oldStream);
                    newStream.Position = 0;
                break;
                case SoapMessageStage.BeforeDeserialize:
                    CopyStream(oldStream, newStream);
                    Log(message, "BeforeDeserialize");
                break;
            case SoapMessageStage.AfterDeserialize:
                break;
        }
    }

    public void Log(SoapMessage message, string stage)
    {

        newStream.Position = 0;
        string contents = (message is SoapServerMessage) ? "SoapRequest " : "SoapResponse ";
        contents += stage + ";";

        StreamReader reader = new StreamReader(newStream);

        contents += reader.ReadToEnd();

        newStream.Position = 0;

        log.Debug(contents);
    }

    void ReturnStream()
    {
        CopyAndReverse(newStream, oldStream);
    }

    void ReceiveStream()
    {
        CopyAndReverse(newStream, oldStream);
    }

    public void ReverseIncomingStream()
    {
        ReverseStream(newStream);
    }

    public void ReverseOutgoingStream()
    {
        ReverseStream(newStream);
    }

    public void ReverseStream(Stream stream)
    {
        TextReader tr = new StreamReader(stream);
        string str = tr.ReadToEnd();
        char[] data = str.ToCharArray();
        Array.Reverse(data);
        string strReversed = new string(data);

        TextWriter tw = new StreamWriter(stream);
        stream.Position = 0;
        tw.Write(strReversed);
        tw.Flush();
    }
    void CopyAndReverse(Stream from, Stream to)
    {
        TextReader tr = new StreamReader(from);
        TextWriter tw = new StreamWriter(to);

        string str = tr.ReadToEnd();
        char[] data = str.ToCharArray();
        Array.Reverse(data);
        string strReversed = new string(data);
        tw.Write(strReversed);
        tw.Flush();
    }

    private void CopyStream(Stream fromStream, Stream toStream)
    {
        try
        {
            StreamReader sr = new StreamReader(fromStream);
            StreamWriter sw = new StreamWriter(toStream);
            sw.WriteLine(sr.ReadToEnd());
            sw.Flush();
        }
        catch (Exception ex)
        {
            string message = String.Format("CopyStream failed because: {0}", ex.Message);
            log.Error(message, ex);
        }
    }
}

[AttributeUsage(AttributeTargets.Method)]
public class SoapLoggerExtensionAttribute : SoapExtensionAttribute
{
    private int priority = 1; 

    public override int Priority

    }

    public override System.Type ExtensionType
    {
        get { return typeof (SoapLoggerExtension); }

}

You then add the following section to your web.config where YourNamespace and YourAssembly point to the class and assembly of your SoapExtension:

<webServices>
  <soapExtensionTypes>
    <add type="YourNamespace.SoapLoggerExtension, YourAssembly" 
       priority="1" group="0" />
  </soapExtensionTypes>
</webServices>

Here is how I do it on iOS 9 in Swift -

import UIKit

class CustomView : UIView {

    init() {
        super.init(frame: UIScreen.mainScreen().bounds);

        //for debug validation
        self.backgroundColor = UIColor.blueColor();
        print("My Custom Init");

        return;
    }

    required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented"); }
}

Since this is a top hit on Google, I'd like to give an updated answer.

Using ES6 classes makes inheritance and method overriding a lot easier:

'use strict';

class A {
    speak() {
        console.log("I'm A");
    }
}

class B extends A {
    speak() {
        super.speak();

        console.log("I'm B");
    }
}

var a = new A();
a.speak();
// Output:
// I'm A

var b = new B();
b.speak();
// Output:
// I'm A
// I'm B

The super keyword refers to the parent class when used in the inheriting class. Also, all methods on the parent class are bound to the instance of the child, so you don't have to write super.method.apply(this);.

As for compatibility: the ES6 compatibility table shows only the most recent versions of the major players support classes (mostly). V8 browsers have had them since January of this year (Chrome and Opera), and Firefox, using the SpiderMonkey JS engine, will see classes next month with their official Firefox 45 release. On the mobile side, Android still does not support this feature, while iOS 9, release five months ago, has partial support.

Fortunately, there is Babel, a JS library for re-compiling Harmony code into ES5 code. Classes, and a lot of other cool features in ES6 can make your Javascript code a lot more readable and maintainable.

It is true that there aren't "before triggers" in MSSQL. However, you could still track the changes that were made on the table, by using the "inserted" and "deleted" tables together. When an update causes the trigger to fire, the "inserted" table stores the new values and the "deleted" table stores the old values. Once having this info, you could relatively easy simulate the "before trigger" behaviour.

The collation you pick sets whether you are case sensitive or not.

When you run your application this way, the java excecutable read the MANIFEST inside your jar and find the main class you defined. In this class you have a static method called main. In this method you may use the command line arguments.

I have seen the same warning when my data has extra space, tabs, newlines or other characters in my column which is decimal(10,2) to solve that, I had to remove those characters from value.

here is how I handled it.

LOAD DATA LOCAL INFILE 'c:/Users/Hitesh/Downloads/InventoryMasterReportHitesh.csv' 
INTO TABLE stores_inventory_tmp 
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS
(@col1, @col2, @col3, @col4, @col5)
SET sku = TRIM(REPLACE(REPLACE(REPLACE(REPLACE(@col1,'\t',''), '$',''), '\r', ''), '\n', ''))
, product_name = TRIM(REPLACE(REPLACE(REPLACE(REPLACE(@col2,'\t',''), '$',''), '\r', ''), '\n', ''))
, department_number = TRIM(REPLACE(REPLACE(REPLACE(REPLACE(@col3,'\t',''), '$',''), '\r', ''), '\n', ''))
, department_name = TRIM(REPLACE(REPLACE(REPLACE(REPLACE(@col4,'\t',''), '$',''), '\r', ''), '\n', ''))
, price = TRIM(REPLACE(REPLACE(REPLACE(REPLACE(@col5,'\t',''), '$',''), '\r', ''), '\n', ''))
;

I've got that hint from this answer

a = "something"
randround = {}
randround['A'] = "%s" % a

Worked.

Almost, we can say Python is interpreted language. But we are using some part of one time compilation process in python to convert complete source code into byte-code like java language.

You cannot update UI from any other thread other than the UI thread. Use this to update thread on the UI thread.

 private void AggiornaContatore()
 {         
     if(this.lblCounter.InvokeRequired)
     {
         this.lblCounter.BeginInvoke((MethodInvoker) delegate() {this.lblCounter.Text = this.index.ToString(); ;});    
     }
     else
     {
         this.lblCounter.Text = this.index.ToString(); ;
     }
 }

I enabled remote errors to pinpoint the problem.

I identified that a column in a particular dataset (one of my views) was throwing an error.

So using a tool "SQL Delta", I compared the development version of the database with the live version on the reporting server. I noticed that one of the views had an extra column on the development server, that was not on the live version of the db.

SQL Delta generated the script I needed to run to update the view on my live db.

I ran this script, re-ran the report, everything worked.

Modules are VB counterparts to C# static classes. When your class is designed solely for helper functions and extension methods and you don't want to allow inheritance and instantiation, you use a Module.

By the way, using Module is not really subjective and it's not deprecated. Indeed you must use a Module when it's appropriate. .NET Framework itself does it many times (System.Linq.Enumerable, for instance). To declare an extension method, it's required to use Modules.

Jan 2020 Update

@Flimm has explained all the differences very well. Generally, we want to know the difference between all tools because we want to decide what's best for us. So, the next question would be: which one to use? I suggest you choose one of the two official ways to manage virtual environments:

• Python Packaging now recommends Pipenv
• Python.org now recommends venv

For small scripts an optional way to make it readable is to use a variable like this:

awk -v fmt="'%s'\n" '{printf fmt, $1}'

I found it conveninet in a case where I had to produce many times the single-quote character in the output and the \047 were making it totally unreadable

We have one more option to do order by

public Cursor getlistbyrank(String rank) {
        try {
//This can be used
return db.`query("tablename", null, null, null, null, null, rank +"DESC",null );
OR
return db.rawQuery("SELECT * FROM table order by rank", null);
        } catch (SQLException sqle) {
            Log.e("Exception on query:-", "" + sqle.getMessage());
            return null;
        }
    }

You can use this two method for order

On mac (BSD find) use:

find /dir1 -type f -exec basename {} \;

use java.nio.channels.FileLock in conjunction with java.nio.channels.FileChannel

There is a way to do this without using a pipe character, which is convenient if you are forking a process from another programming language to do this:

find $JAVA_SRC_DIR -name '*.java' -exec javac -d $OUTPUT_DIR {} +

Though if you are in Bash and/or don't mind using a pipe, then you can do:

find $JAVA_SRC_DIR -name '*.java' | xargs javac -d $OUTPUT_DIR

The first thing to do is to check the details of the error message. For this you could use the LogCat App.

For me the problem was an error like

Cannot rename native library directory /data/app-lib/vmdl-... to /data/app-lib/com.xyz

The solution was to activate the common sense function in my brain and look for the com.xyz folder in the app-lib folder with ES-Explorer. I recognized that this folder was already there. So removing it solved the renaming problem and the apps can now install properly.

To reset a specific file to the last-committed state (to discard uncommitted changes in a specific file):

git checkout thefiletoreset.txt

This is mentioned in the git status output:

(use "git checkout -- <file>..." to discard changes in working directory)

To reset the entire repository to the last committed state:

git reset --hard

To remove untracked files, I usually just delete all files in the working copy (but not the .git/ folder!), then do git reset --hard which leaves it with only committed files.

A better way is to use git clean (warning: using the -x flag as below will cause Git to delete ignored files):

git clean -d -x -f

will remove untracked files, including directories (-d) and files ignored by git (-x). Replace the -f argument with -n to perform a dry-run or -i for interactive mode, and it will tell you what will be removed.

Relevant links:

• git-reset man page
• git-clean man page
• git ready "cleaning up untracked files" (as Marko posted)
• Stack Overflow question "How to remove local (untracked) files from the current Git working tree")

If the POM missing warning is of project's self module, the reason is that you are trying to mistakenly build from a sub-module directory. You need to run the build and install command from root directory of the project.

According to the below scenario ,

Let's say that someone makes a request to your server with data that is in the correct format, but is simply not "good" data. So for example, imagine that someone posted a String value to an API endpoint that expected a String value; but, the value of the string contained data that was blacklisted (ex. preventing people from using "password" as their password). then the status code could be either 400 or 422 ?

Until now, I would have returned a "400 Bad Request", which, according to the w3.org, means:

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

This description doesn't quite fit the circumstance; but, if you go by the list of core HTTP status codes defined in the HTTP/1.1 protocol, it's probably your best bet.

Recently, however, Someone from my Dev team pointed out [to me] that popular APIs are starting to use HTTP extensions to get more granular with their error reporting. Specifically, many APIs, like Twitter and Recurly, are using the status code "422 Unprocessable Entity" as defined in the HTTP extension for WebDAV. HTTP status code 422 states:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

Going back to our password example from above, this 422 status code feels much more appropriate. The server understands what you're trying to do; and it understands the data that you're submitting; it simply won't let that data be processed.

Try this. It will check to see if the file already exists in the destination folder, and if it does will check if the file is read-only. If the file is read-only it will change it to read-write, replace the file, and make it read-only again.

Const DestinationFile = "c:\destfolder\anyfile.txt"
Const SourceFile = "c:\sourcefolder\anyfile.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
    'Check to see if the file already exists in the destination folder
    If fso.FileExists(DestinationFile) Then
        'Check to see if the file is read-only
        If Not fso.GetFile(DestinationFile).Attributes And 1 Then 
            'The file exists and is not read-only.  Safe to replace the file.
            fso.CopyFile SourceFile, "C:\destfolder\", True
        Else 
            'The file exists and is read-only.
            'Remove the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes - 1
            'Replace the file
            fso.CopyFile SourceFile, "C:\destfolder\", True
            'Reapply the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes + 1
        End If
    Else
        'The file does not exist in the destination folder.  Safe to copy file to this folder.
        fso.CopyFile SourceFile, "C:\destfolder\", True
    End If
Set fso = Nothing

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

Figured it out... it's a little cumbersome, but here it is.

FROM_DAYS(TO_DAYS(TIMESTAMP) -MOD(TO_DAYS(TIMESTAMP) -1, 7))

And, if your business rules say your weeks start on Mondays, change the -1 to -2.

Edit

Years have gone by and I've finally gotten around to writing this up. http://www.plumislandmedia.net/mysql/sql-reporting-time-intervals/

Inspired by the answers above, especially by Sagar Gala, I've created this API. You may use it if you don't want or can't upgrade your jquery version.

With regard to performance, here are some numbers comparing python lists, arrays and numpy arrays (all with Python 3.7 on a 2017 Macbook Pro). The end result is that the python list is fastest for these operations.

# Python list with append()
np.mean(timeit.repeat(setup="a = []", stmt="a.append(1.0)", number=1000, repeat=5000)) * 1000
# 0.054 +/- 0.025 msec

# Python array with append()
np.mean(timeit.repeat(setup="import array; a = array.array('f')", stmt="a.append(1.0)", number=1000, repeat=5000)) * 1000
# 0.104 +/- 0.025 msec

# Numpy array with append()
np.mean(timeit.repeat(setup="import numpy as np; a = np.array([])", stmt="np.append(a, [1.0])", number=1000, repeat=5000)) * 1000
# 5.183 +/- 0.950 msec

# Python list using +=
np.mean(timeit.repeat(setup="a = []", stmt="a += [1.0]", number=1000, repeat=5000)) * 1000
# 0.062 +/- 0.021 msec

# Python array using += 
np.mean(timeit.repeat(setup="import array; a = array.array('f')", stmt="a += array.array('f', [1.0]) ", number=1000, repeat=5000)) * 1000
# 0.289 +/- 0.043 msec

# Python list using extend()
np.mean(timeit.repeat(setup="a = []", stmt="a.extend([1.0])", number=1000, repeat=5000)) * 1000
# 0.083 +/- 0.020 msec

# Python array using extend()
np.mean(timeit.repeat(setup="import array; a = array.array('f')", stmt="a.extend([1.0]) ", number=1000, repeat=5000)) * 1000
# 0.169 +/- 0.034

When your React app is massive, it really takes time for it to get up and running after the page has been loaded. Say, you mount your React part of the app to #app. Usually, this element in your index.html is simply an empty div:

<div id="app"></div>

What you can do instead is put some styling and a bunch of images there to make it look better between page load and initial React app rendering to DOM:

<div id="app">
  <div class="logo">
    <img src="/my/cool/examplelogo.svg" />
  </div>
  <div class="preload-title">
    Hold on, it's loading!
  </div>
</div>

After the page loads, user will immediately see the original content of index.html. Shortly after, when React is ready to mount the whole hierarchy of rendered components to this DOM node, user will see the actual app.

Note class, not className. It's because you need to put this into your html file.

If you use SSR, things are less complicated because the user will actually see the real app right after the page loads.

I believe, the 500ms run in the background, while the rest of the code continues to execute and empties the list.

Then after 500ms nothing happens, as no function-call is implemented in the after-callup (same as frame.after(500, function=None))

This works for me:

#! /bin/bash

CACERTS=$(readlink -e $(dirname $(readlink -e $(which keytool)))/../lib/security/cacerts)

if keytool -list -keystore $CACERTS -storepass changeit > /dev/null ; then
    echo $CACERTS
else
    echo 'Can not find cacerts file.' >&2
    exit 1
fi

Only for Linux. My Solaris has no readlink. In the end I used this Perl-Script:

#! /usr/bin/env perl
use strict;
use warnings;
use Cwd qw(realpath);
$_ = realpath((grep {-x && -f} map {"$_/keytool"} split(':', $ENV{PATH}))[0]);
die "Can not find keytool" unless defined $_;
my $keytool = $_;
print "Using '$keytool'.\n";
s/keytool$//;
$_ = realpath($_ . '../lib/security/cacerts');
die "Can not find cacerts" unless -f $_;
my $cacerts = $_;
print "Importing into '$cacerts'.\n";
`$keytool -list -keystore "$cacerts" -storepass changeit`;
die "Can not read key container" unless $? == 0;
exit if $ARGV[0] eq '-d';
foreach (@ARGV) {
    my $cert = $_;
    s/\.[^.]+$//;
    my $alias = $_;
    print "Importing '$cert' as '$alias'.\n";
    `keytool -importcert -file "$cert" -alias "$alias" -keystore "$cacerts" -storepass changeit`;
    warn "Can not import certificate: $?" unless $? == 0;
}

It is working fine with me.

I have the following HTML:

<div>
    <select id="select1">
        <option value="1">test1</option>
        <option value="2" selected="selected">test2</option>
        <option value="3">test3</option>
    </select>
    <br/>
    <button onClick="GetSelectedItem('select1');">Get Selected Item</button>
</div>

And the following JavaScript:

function GetSelectedItem(el)
{
    var e = document.getElementById(el);
    var strSel = "The Value is: " + e.options[e.selectedIndex].value + " and text is: " + e.options[e.selectedIndex].text;
    alert(strSel);
}

See that you are using the right id. In case you are using it with ASP.NET, the id changes when rendered.

You could access your class's __dict__ attribute:

for i in range(3)
     self.__dict__['group%d' % i]=self.getGroup(selected, header+i)

But why can't you just use an array named group?

You can temporarily disable timestamps

$timestamps = $user->timestamps;
$user->timestamps=false;   // avoid view updating the timestamp

$user->last_logged_in_at = now();
$user->save();

$user->timestamps=$timestamps;   // restore timestamps

And another solution is Google reflections.

Quick review:

• Spring solution is the way to go if you're using Spring. Otherwise it's a big dependency.
• Using ASM directly is a bit cumbersome.
• Using Java Assist directly is clunky too.
• Annovention is super lightweight and convenient. No maven integration yet.
• Google reflections pulls in Google collections. Indexes everything and then is super fast.

Try:

git config core.fileMode false

From git-config(1):

core.fileMode
    Tells Git if the executable bit of files in the working tree
    is to be honored.

    Some filesystems lose the executable bit when a file that is
    marked as executable is checked out, or checks out a
    non-executable file with executable bit on. git-clone(1)
    or git-init(1) probe the filesystem to see if it handles the 
    executable bit correctly and this variable is automatically
    set as necessary.

    A repository, however, may be on a filesystem that handles
    the filemode correctly, and this variable is set to true when
    created, but later may be made accessible from another
    environment that loses the filemode (e.g. exporting ext4
    via CIFS mount, visiting a Cygwin created repository with Git
    for Windows or Eclipse). In such a case it may be necessary
    to set this variable to false. See git-update-index(1).

    The default is true (when core.filemode is not specified
    in the config file).

The -c flag can be used to set this option for one-off commands:

git -c core.fileMode=false diff

And the --global flag will make it be the default behavior for the logged in user.

git config --global core.fileMode false

Changes of the global setting won't be applied to existing repositories. Additionally, git clone and git init explicitly set core.fileMode to true in the repo config as discussed in Git global core.fileMode false overridden locally on clone

Warning

core.fileMode is not the best practice and should be used carefully. This setting only covers the executable bit of mode and never the read/write bits. In many cases you think you need this setting because you did something like chmod -R 777, making all your files executable. But in most projects most files don't need and should not be executable for security reasons.

The proper way to solve this kind of situation is to handle folder and file permission separately, with something like:

find . -type d -exec chmod a+rwx {} \; # Make folders traversable and read/write
find . -type f -exec chmod a+rw {} \;  # Make files read/write

If you do that, you'll never need to use core.fileMode, except in very rare environment.

For someone who is new to IPC and Named Pipes, I found the following NuGet package to be a great help.

GitHub: Named Pipe Wrapper for .NET 4.0

To use first install the package:

PS> Install-Package NamedPipeWrapper

Then an example server (copied from the link):

var server = new NamedPipeServer<SomeClass>("MyServerPipe");
server.ClientConnected += delegate(NamedPipeConnection<SomeClass> conn)
    {
        Console.WriteLine("Client {0} is now connected!", conn.Id);
        conn.PushMessage(new SomeClass { Text: "Welcome!" });
    };

server.ClientMessage += delegate(NamedPipeConnection<SomeClass> conn, SomeClass message)
    {
        Console.WriteLine("Client {0} says: {1}", conn.Id, message.Text);
    };

server.Start();

Example client:

var client = new NamedPipeClient<SomeClass>("MyServerPipe");
client.ServerMessage += delegate(NamedPipeConnection<SomeClass> conn, SomeClass message)
    {
        Console.WriteLine("Server says: {0}", message.Text);
    };

client.Start();

Best thing about it for me is that unlike the accepted answer here it supports multiple clients talking to a single server.

As of Hive version 0.14.0: INSERT...VALUES, UPDATE, and DELETE are now available with full ACID support.

INSERT ... VALUES Syntax:

INSERT INTO TABLE tablename [PARTITION (partcol1[=val1], partcol2[=val2] ...)] VALUES values_row [, values_row ...]

Where values_row is: ( value [, value ...] ) where a value is either null or any valid SQL literal

UPDATE Syntax:

UPDATE tablename SET column = value [, column = value ...] [WHERE expression]

DELETE Syntax:

DELETE FROM tablename [WHERE expression]

Additionally, from the Hive Transactions doc:

If a table is to be used in ACID writes (insert, update, delete) then the table property "transactional" must be set on that table, starting with Hive 0.14.0. Without this value, inserts will be done in the old style; updates and deletes will be prohibited.

Hive DML reference:
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML
Hive Transactions reference:
https://cwiki.apache.org/confluence/display/Hive/Hive+Transactions

If you want to list all the files currently being tracked under the branch master, you could use this command:

git ls-tree -r master --name-only

If you want a list of files that ever existed (i.e. including deleted files):

git log --pretty=format: --name-only --diff-filter=A | sort - | sed '/^$/d'

Without using 'length' you can do it like this:

if ($('input[type=checkbox]').is(":checked")) {
      //any one is checked
}
else {
//none is checked
}

I tried @PhilNicholas 's code and got the same problem of @its_me said in the comments that search bar show up on the next line of navbar, and I found that form need to be added an attribute width.

<form role="search" style="width: 15em; margin: 0.3em 2em;">
    <div class="input-group">
        <input type="text" class="form-control" placeholder="Search">
        <div class="input-group-btn">
            <button type="submit" class="btn btn-default">
                <span class="glyphicon glyphicon-search"></span>
            </button>
        </div>
    </div>
</form> 

Swift 2.0

Pass info using userInfo which is a optional Dictionary of type [NSObject : AnyObject]?

  let imageDataDict:[String: UIImage] = ["image": image]

  // Post a notification
  NSNotificationCenter.defaultCenter().postNotificationName(notificationName, object: nil, userInfo: imageDataDict)

 // Register to receive notification in your class
 NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: notificationName, object: nil)

 // handle notification
 func showSpinningWheel(notification: NSNotification) { 

  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
 }

Swift 3.0 version and above

The userInfo now takes [AnyHashable:Any]? as an argument, which we provide as a dictionary literal in Swift

  let imageDataDict:[String: UIImage] = ["image": image]

  // post a notification
  NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationName"), object: nil, userInfo: imageDataDict) 
  // `default` is now a property, not a method call

 // Register to receive notification in your class
 NotificationCenter.default.addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: NSNotification.Name(rawValue: "notificationName"), object: nil)

 // handle notification
 // For swift 4.0 and above put @objc attribute in front of function Definition  
 func showSpinningWheel(_ notification: NSNotification) {

  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
 }

NOTE: Notification “names” are no longer strings, but are of type Notification.Name, hence why we are using NSNotification.Name(rawValue:"notificationName") and we can extend Notification.Name with our own custom notifications.

extension Notification.Name {
static let myNotification = Notification.Name("myNotification")
}

// and post notification like this
NotificationCenter.default.post(name: .myNotification, object: nil)

You can either

import * as abc from './abc';
abc.xyz();

or

import { xyz } from './abc';
xyz()

The package @angular/router has the Resolve property for routes. So you can easily resolve data before rendering a route view.

See: https://angular.io/docs/ts/latest/api/router/index/Resolve-interface.html

Example from docs as of today, August 28, 2017:

class Backend {
  fetchTeam(id: string) {
    return 'someTeam';
  }
}

@Injectable()
class TeamResolver implements Resolve<Team> {
  constructor(private backend: Backend) {}

  resolve(
    route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<any>|Promise<any>|any {
    return this.backend.fetchTeam(route.params.id);
  }
}

@NgModule({
  imports: [
    RouterModule.forRoot([
      {
        path: 'team/:id',
        component: TeamCmp,
        resolve: {
          team: TeamResolver
        }
      }
    ])
  ],
  providers: [TeamResolver]
})
class AppModule {}

Now your route will not be activated until the data has been resolved and returned.

Accessing Resolved Data In Your Component

To access the resolved data from within your component at runtime, there are two methods. So depending on your needs, you can use either:

1. route.snapshot.paramMap which returns a string, or the
2. route.paramMap which returns an Observable you can .subscribe() to.

Example:

  // the no-observable method
  this.dataYouResolved= this.route.snapshot.paramMap.get('id');
  // console.debug(this.licenseNumber);

  // or the observable method
  this.route.paramMap
     .subscribe((params: ParamMap) => {
        // console.log(params);
        this.dataYouResolved= params.get('id');
        return params.get('dataYouResolved');
        // return null
     });
  console.debug(this.dataYouResolved);

I hope that helps.

I used format() method to make a load bar. Here is my solution:

import time

loadbarwidth = 23

for i in range(1, loadbarwidth + 1):
    time.sleep(0.1) 

    strbarwidth = '[{}{}] - {}\r'.format(
        (i * '#'),
        ((loadbarwidth - i) * '-'),
        (('{:0.2f}'.format(((i) * (100/loadbarwidth))) + '%'))
    )

    print(strbarwidth ,end = '')

print()

Output:

Use <label> for the caption

<form enctype='multipart/form-data' action='/uploads.php' method=post>
<label for=b1>
    <u>Your</u> caption here
<input style='width:0px' type=file name=upfile id=b1
 onchange='optionalExtraProcessing(b1.files[0])'
 accept='image/png'>
</label>
</form>

This works without any javascript. You can decorate the label to any degree of complexity, to your heart's content. When you click on the label, the click automatically gets redirected to the file input. The file input itself can be made invisible by any method. If you want the label to appear like a button, there are many solutions, e.g.:

label u {
    -webkit-appearance: button;
    -moz-appearance: button;
    appearance: button;

    text-decoration: none;
    color: initial;
}

The right way is 1) Download and Install python 2.7.14 from here. 2) Set environment variable for python from here.

done!

note: Please set environment variable accordingly. I answered here for windows.

Try this:

git checkout [revision] .

where [revision] is the commit hash (for example: 12345678901234567890123456789012345678ab).

Don't forget the . at the end, very important. This will apply changes to the whole tree. You should execute this command in the git project root. If you are in any sub directory, then this command only changes the files in the current directory. Then commit and you should be good.

You can undo this by

git reset --hard 

that will delete all modifications from the working directory and staging area.

$configValue = Mage::getStoreConfig('sectionName/groupName/fieldName');

sectionName, groupName and fieldName are present in etc/system.xml file of your module.

The above code will automatically fetch config value of currently viewed store.

If you want to fetch config value of any other store than the currently viewed store then you can specify store ID as the second parameter to the getStoreConfig function as below:

$store = Mage::app()->getStore(); // store info
$configValue = Mage::getStoreConfig('sectionName/groupName/fieldName', $store);

The latest PowerShell version as of Sept 2015 is PowerShell 4.0. It's bundled with Windows Management Framework 4.0.

Here's the download page for PowerShelll 4.0 for all versions of Windows. For Windows 7, there are 2 links on that page, 1 for x64 and 1 for x86.

I just wanted to mention that one can get the detailed GC log with the

-XX:+PrintGCDetails 

parameter. Then you see the PSYoungGen or PSPermGen output like in the answer.

Also -Xloggc:gc.log seems to generate the same output like -verbose:gc but you can specify an output file in the first.

Example usage:

java -Xloggc:./memory.log -XX:+PrintGCDetails Memory

To visualize the data better you can try gcviewer (a more recent version can be found on github).

Take care to write the parameters correctly, I forgot the "+" and my JBoss would not start up, without any error message!

I was adding a dollar sign twice in an expression with curly braces in bash:

cp -r $PROJECT_NAME ${$PROJECT_NAME}2

instead of

cp -r $PROJECT_NAME ${PROJECT_NAME}2

SELECT CONVERT(VARCHAR(10), GETDATE(), 105) + ' ' + CONVERT(VARCHAR(10), GETDATE(), 108)

And here is what I use, and it's pretty uncomplicated:

print(np.vectorize("%.2f".__mod__)(sparse))

I am using Entity Framework to repupulate my database, and the users gets overridden each time I generate my database.

Now I run this each time I load a new DBContext:

cnt.Database.ExecuteSqlCommand("EXEC sp_addrolemember 'db_owner', 'NT AUTHORITY\\NETWORK SERVICE'");

My preferred solution is:

class MyClass:
    _data = []
    __init__(self,data=None):
        # do init stuff
        if not data: return
        self._data = list(data) # list() copies the list, instead of pointing to it.

Then invoke it with either MyClass() or MyClass([1,2,3]).

Hope that helps. Happy Coding!

If you want to switch only for once use this

nvm use 12.x

Else if you want to switch the default node version then use

nvm use default 12.x

If you're using Bootstrap 4:

<form class="d-flex">
  <label for="myInput" class="align-items-center">Sample label</label>
  <input type="text" id="myInput" placeholder="Sample Input" class="flex-grow-1"/>
</form>

Better yet, use what's built into Bootstrap:

  <form>

        if(numbers[i]=='1')
            result += Math.pow(2, (numbers.length-i - 1));
    return result;
}

If you just want to rearrange dates from oldest to newest in r etc. you can always do:

To answer the question asked, here is the most accurate SQL to accomplish the job, you can combine it with PL/SQL loop to actually run kill statements:

select ses.USERNAME,
    substr(MACHINE,1,10) as MACHINE, 
    substr(module,1,25) as module,
    status, 
    'alter system kill session '''||SID||','||ses.SERIAL#||''';' as kill
from v$session ses LEFT OUTER JOIN v$process p ON (ses.paddr=p.addr)
where schemaname <> 'SYS'
    and not exists
    (select 1 
        from DBA_ROLE_PRIVS 
        where GRANTED_ROLE='DBA' 
            and schemaname=grantee)
    and machine!='yourlocalhostname' 
order by LAST_CALL_ET desc;

A trick:

Use MAMPPRO and create: server name: the EXACT adress of you website (eg: helloworld.com) to your site on your disk

On Facebook: So you can keep your original Site URL as well (eg: helloworld.com)

Now you understand that when you type your website on the adress bar you are in local! ..and when you want to be online, just inactive the server on MAMP PRO..

You can try using open-cv to save the file since it helps with image type conversions internally. The sample code:

import cv2
import numpy as np

def save(encoded_data, filename):
    nparr = np.fromstring(encoded_data.decode('base64'), np.uint8)
    img = cv2.imdecode(nparr, cv2.IMREAD_ANYCOLOR)
    return cv2.imwrite(filename, img)

Then somewhere in your code you can use it like this:

save(base_64_string, 'testfile.png');
save(base_64_string, 'testfile.jpg');
save(base_64_string, 'testfile.bmp');

Yes, I think hashing the file would be the best way if you have to compare several files and store hashes for later comparison. As hash can clash, a byte-by-byte comparison may be done depending on the use case.

Generally byte-by-byte comparison would be sufficient and efficient, which filecmp module already does + other things too.

See http://docs.python.org/library/filecmp.html e.g.

>>> import filecmp
>>> filecmp.cmp('file1.txt', 'file1.txt')
True
>>> filecmp.cmp('file1.txt', 'file2.txt')
False

Speed consideration: Usually if only two files have to be compared, hashing them and comparing them would be slower instead of simple byte-by-byte comparison if done efficiently. e.g. code below tries to time hash vs byte-by-byte

Disclaimer: this is not the best way of timing or comparing two algo. and there is need for improvements but it does give rough idea. If you think it should be improved do tell me I will change it.

import random
import string
import hashlib
import time

def getRandText(N):
    return  "".join([random.choice(string.printable) for i in xrange(N)])

N=1000000
randText1 = getRandText(N)
randText2 = getRandText(N)

def cmpHash(text1, text2):
    hash1 = hashlib.md5()
    hash1.update(text1)
    hash1 = hash1.hexdigest()

    hash2 = hashlib.md5()
    hash2.update(text2)
    hash2 = hash2.hexdigest()

    return  hash1 == hash2

def cmpByteByByte(text1, text2):
    return text1 == text2

for cmpFunc in (cmpHash, cmpByteByByte):
    st = time.time()
    for i in range(10):
        cmpFunc(randText1, randText2)
    print cmpFunc.func_name,time.time()-st

and the output is

cmpHash 0.234999895096
cmpByteByByte 0.0
