You need to create your own Prompt dialog. You could perhaps create a class for this.

public static class Prompt
{
    public static string ShowDialog(string text, string caption)
    {
        Form prompt = new Form()
        {
            Width = 500,
            Height = 150,
            FormBorderStyle = FormBorderStyle.FixedDialog,
            Text = caption,
            StartPosition = FormStartPosition.CenterScreen
        };
        Label textLabel = new Label() { Left = 50, Top=20, Text=text };
        TextBox textBox = new TextBox() { Left = 50, Top=50, Width=400 };
        Button confirmation = new Button() { Text = "Ok", Left=350, Width=100, Top=70, DialogResult = DialogResult.OK };
        confirmation.Click += (sender, e) => { prompt.Close(); };
        prompt.Controls.Add(textBox);
        prompt.Controls.Add(confirmation);
        prompt.Controls.Add(textLabel);
        prompt.AcceptButton = confirmation;

        return prompt.ShowDialog() == DialogResult.OK ? textBox.Text : "";
    }
}

And calling it:

string promptValue = Prompt.ShowDialog("Test", "123");

Update:

Added default button (enter key) and initial focus based on comments and another question.

In my humble opinion, this is just a matter of deciding if the arguments are optional or not. If an Person object shouldn't (logically) exist without Name and Age, they should be mandatory in the constructor. If they are optional, (i.e. their absence is not a threat to the good functioning of the object), use the setters.

Here's a quote from Symfony's docs on constructor injection:

There are several advantages to using constructor injection:

• If the dependency is a requirement and the class cannot work without it then injecting it via the constructor ensures it is present when the class is used as the class cannot be constructed without it.
• The constructor is only ever called once when the object is created, so you can be sure that the dependency will not change during the object's lifetime.

These advantages do mean that constructor injection is not suitable for working with optional dependencies. It is also more difficult to use in combination with class hierarchies: if a class uses constructor injection then extending it and overriding the constructor becomes problematic.

(Symfony is one of the most popular and respected php frameworks)

I had the same problem earlier today. I could not figure out why the class file I was trying to reference was not being seen by the compiler. I had recently changed the namespace of the class file in question to a different but already existing namespace. (I also had using references to the class's new and previous namespaces where I was trying to instantiate it)

Where the compiler was telling me I was missing a reference when trying to instantiate the class, I right clicked and hit "generate class stub". Once Visual Studio generated a class stub for me, I coped and pasted the code from the old class file into this stub, saved the stub and when I tried to compile again it worked! No issues.

Might be a solution specific to my build, but its worth a try.

KOTLIN setting more than one gravity on FrameLayout without changing size:

     // assign more than one gravity,Using the operator "or"
    var gravity = Gravity.RIGHT or Gravity.CENTER_VERTICAL
     // update gravity
    (pagerContainer.layoutParams as FrameLayout.LayoutParams).gravity = gravity
     // refresh layout
     pagerContainer.requestLayout()

First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.

Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.

Here's how you should do it with all the suggestions above:

public enum States {
    ...
    MASSACHUSETTS("Massachusetts",  "MA",   true),
    MICHIGAN     ("Michigan",       "MI",   false),
    ...; // all 50 of those

    private final String full;
    private final String abbr;
    private final boolean originalColony;

    private States(String full, String abbr, boolean originalColony) {
        this.full = full;
        this.abbr = abbr;
        this.originalColony = originalColony;
    }

    public String getFullName() {
        return full;
    }

    public String getAbbreviatedName() {
        return abbr;
    }

    public boolean isOriginalColony(){
        return originalColony;
    }
}

This is called the "shape" in NumPy, and can be requested via the .shape attribute:

>>> a = zeros((2, 5))
>>> a.shape
(2, 5)

If you prefer a function, you could also use numpy.shape(a).

It means that the callback function you passed to this.dataStore.data.find should return a boolean and have 3 parameters, two of which can be optional:

• value: Conversations
• index: number
• obj: Conversation[]

However, your callback function does not return anything (returns void). You should pass a callback function with the correct return value:

this.dataStore.data.find((element, index, obj) => {
    // ...

    return true; // or false
});

or:

this.dataStore.data.find(element => {
    // ...

    return true; // or false
});

Reason why it's this way: the function you pass to the find method is called a predicate. The predicate here defines a boolean outcome based on conditions defined in the function itself, so that the find method can determine which value to find.

In practice, this means that the predicate is called for each item in data, and the first item in data for which your predicate returns true is the value returned by find.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

For #4, the closest thing to starting java with a jar file for your app is a new feature in Python 2.6, executable zip files and directories.

python myapp.zip

Where myapp.zip is a zip containing a __main__.py file which is executed as the script file to be executed. Your package dependencies can also be included in the file:

__main__.py
mypackage/__init__.py
mypackage/someliblibfile.py

You can also execute an egg, but the incantation is not as nice:

# Bourn Shell and derivatives (Linux/OSX/Unix)
PYTHONPATH=myapp.egg python -m myapp

rem Windows 
set PYTHONPATH=myapp.egg
python -m myapp

This puts the myapp.egg on the Python path and uses the -m argument to run a module. Your myapp.egg will likely look something like:

myapp/__init__.py
myapp/somelibfile.py

And python will run __init__.py (you should check that __file__=='__main__' in your app for command line use).

Egg files are just zip files so you might be able to add __main__.py to your egg with a zip tool and make it executable in python 2.6 and run it like python myapp.egg instead of the above incantation where the PYTHONPATH environment variable is set.

More information on executable zip files including how to make them directly executable with a shebang can be found on Michael Foord's blog post on the subject.

According to the answer of @scx ,I created a validation for GUI

app.directive('validateEmail', function() {
  var EMAIL_REGEXP = /^[_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/;
  return {
    link: function(scope, elm) {
      elm.on("keyup",function(){
            var isMatchRegex = EMAIL_REGEXP.test(elm.val());
            if( isMatchRegex&& elm.hasClass('warning') || elm.val() == ''){
              elm.removeClass('warning');
            }else if(isMatchRegex == false && !elm.hasClass('warning')){
              elm.addClass('warning');
            }
      });
    }
  }
});

And simply add :

css

.warning{
   border:1px solid red;
 }

html

<input type='email' validate-email name='email' id='email' ng-model='email' required>

Just do this:

private void setImg(ImageView mImageView, Bitmap bitmap) {

    Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
    mImageView.setDrawable(mDrawable);
}

If you do not mind using numpy (import numpy as np):

np.partition(numbers, -2)[-2]

gives you the 2nd largest element of the list with a guaranteed worst-case O(n) running time.

The partition(a, kth) methods returns an array where the kth element is the same it would be in a sorted array, all elements before are smaller, and all behind are larger.

Java does not check consistency in a strict sense, only notifies you if it runs into serious trouble. Also it does not give you much information from the error.

I was puzzled with what's happening in my sorter and made a strict consistencyChecker, maybe this will help you:

        getListSafely(objectMapSmallerOnes, o2).add(o1);
      } else if (Compare.EQUAL < diff) {

        getListSafely(objectMapSmallerOnes, o1).add(o2);
      } else {

      }

}

For your specific example, you don't actually need to nest them. If the expression in the try block succeeds, the function will return, so any code after the whole try/except block will only be run if the first attempt fails. So you can just do:

def __getattribute__(self, item):
    try:
        return object.__getattribute__(item)
    except AttributeError:
        pass
    # execution only reaches here when try block raised AttributeError
    try:
        return self.dict[item]
    except KeyError:
        print "The object doesn't have such attribute"

Nesting them isn't bad, but I feel like leaving it flat makes the structure more clear: you're sequentially trying a series of things and returning the first one that works.

Incidentally, you might want to think about whether you really want to use __getattribute__ instead of __getattr__ here. Using __getattr__ will simplify things because you'll know that the normal attribute lookup process has already failed.

Assuming B is the current branch:

$ git diff A <file-path> > patch.tmp
$ git apply patch.tmp -R

Note that this only applies changes to the local file. You'll need to commit afterwards.

1. Open your sql file in a text editor (like Notepad)
2. Select All -> Copy
3. Go to phpMyAdmin, select your database and go to SQL tab
4. Paste the content you have copied in clipboard
5. It might popup a javascript error, ignore it
6. Execute

document.querySelectorAll("#yourId"); returns all elements whose id is yourId

This post has been up for 4 years and I still struggled with this conversion problem - so the issue is still active in 2017 in some sense. I was somewhat shocked that the numpy documentation does not readily offer a simple conversion algorithm but that's another story.

I have come across another way to do the conversion that only involves modules numpy and datetime, it does not require pandas to be imported which seems to me to be a lot of code to import for such a simple conversion. I noticed that datetime64.astype(datetime.datetime) will return a datetime.datetime object if the original datetime64 is in micro-second units while other units return an integer timestamp. I use module xarray for data I/O from Netcdf files which uses the datetime64 in nanosecond units making the conversion fail unless you first convert to micro-second units. Here is the example conversion code,

import numpy as np
import datetime

def convert_datetime64_to_datetime( usert: np.datetime64 )->datetime.datetime:
    t = np.datetime64( usert, 'us').astype(datetime.datetime)
return t

Its only tested on my machine, which is Python 3.6 with a recent 2017 Anaconda distribution. I have only looked at scalar conversion and have not checked array based conversions although I'm guessing it will be good. Nor have I looked at the numpy datetime64 source code to see if the operation makes sense or not.

Google also provides a joiner class in their Google Collections library:

Joiner API

Google Collections

string temp = mystring.Replace("\n", " ");

This returns max heap size in bytes:

Runtime.getRuntime().maxMemory()

I was using ActivityManager.getMemoryClass() but on CyanogenMod 7 (I didn't test it elsewhere) it returns wrong value if the user sets heap size manually.

Everything is much simpler, use git checkout for that.

Suppose you're on master branch, to get app.js from new-feature branch do:

git checkout new-feature path/to/app.js

// note that there is no leading slash in the path!

This will bring you the contents of the desired file. You can, as always, use part of sha1 instead of new-feature branch name to get the file as it was in that particular commit.

Note:new-feature needs to be a local branch, not a remote one.

This function detect collisions (intersections) between Circle and Rectangle. He works like e.James method in his answer, but this one detect collisions for all angles of rectangle (not only right up corner).

NOTE:

aRect.origin.x and aRect.origin.y are coordinates of bottom left angle of rectangle!

aCircle.x and aCircle.y are coordinates of Circle Center!

static inline BOOL RectIntersectsCircle(CGRect aRect, Circle aCircle) {

    float testX = aCircle.x;
    float testY = aCircle.y;

    if (testX < aRect.origin.x)
        testX = aRect.origin.x;
    if (testX > (aRect.origin.x + aRect.size.width))
        testX = (aRect.origin.x + aRect.size.width);
    if (testY < aRect.origin.y)
        testY = aRect.origin.y;
    if (testY > (aRect.origin.y + aRect.size.height))
        testY = (aRect.origin.y + aRect.size.height);

    return ((aCircle.x - testX) * (aCircle.x - testX) + (aCircle.y - testY) * (aCircle.y - testY)) < aCircle.radius * aCircle.radius;
}

Added more complex example with "custom validation" on the side of controller http://jsfiddle.net/82PX4/3/

<div class='line' ng-repeat='line in ranges' ng-form='lineForm'>
    low: <input type='text' 
                name='low'

                ng-pattern='/^\d+$/'
                ng-change="upChanged(this, $index)" 
                ng-model='line.up' />
    <a href ng-if='!$first' ng-click='removeRange($index)'>Delete</a>

    <div class='error' ng-show='lineForm.$error.range'>
        Low must be less the Up.

In C++, there is only a subtle difference. It's a holdover from C, in which it makes a difference.

The C language standard (C89 §3.1.2.3, C99 §6.2.3, and C11 §6.2.3) mandates separate namespaces for different categories of identifiers, including tag identifiers (for struct/union/enum) and ordinary identifiers (for typedef and other identifiers).

If you just said:

struct Foo { ... };
Foo x;

you would get a compiler error, because Foo is only defined in the tag namespace.

You'd have to declare it as:

struct Foo x;

Any time you want to refer to a Foo, you'd always have to call it a struct Foo. This gets annoying fast, so you can add a typedef:

struct Foo { ... };
typedef struct Foo Foo;

Now struct Foo (in the tag namespace) and just plain Foo (in the ordinary identifier namespace) both refer to the same thing, and you can freely declare objects of type Foo without the struct keyword.

The construct:

typedef struct Foo { ... } Foo;

is just an abbreviation for the declaration and typedef.

Finally,

typedef struct { ... } Foo;

declares an anonymous structure and creates a typedef for it. Thus, with this construct, it doesn't have a name in the tag namespace, only a name in the typedef namespace. This means it also cannot be forward-declared. If you want to make a forward declaration, you have to give it a name in the tag namespace.

In C++, all struct/union/enum/class declarations act like they are implicitly typedef'ed, as long as the name is not hidden by another declaration with the same name. See Michael Burr's answer for the full details.

For what it's worth, checking which curl is being run is significant too.

A user on a shared machine I maintain had been getting this error. But the cause turned out to be because they'd installed Anaconda (http://continuum.io). Doing so put Anaconda's binary path before the standard $PATH, and it comes with its own curl binary, which had trouble finding the default certs that were installed on this Ubuntu machine.

FYI: If you are setting the value, and not seeing anything - you might check to see if you have a 'CustomFormat' set - I just hit this and it was set to ' ' for the 1/1/1900 value (our 'not set' value) and set to MM/dd/yyyy if not.

For each iteration of the ng-repeat loop, line is a reference to an object in your array. Therefore, to preview the value, use {{line.text}}.

Similarly, to databind to the text, databind to the same: ng-model="line.text". You don't need to use value when using ng-model (actually you shouldn't).

Fiddle.

For a more in-depth look at scopes and ng-repeat, see What are the nuances of scope prototypal / prototypical inheritance in AngularJS?, section ng-repeat.

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

Ive a really hacky solution with this...

<style type="text/css"> 
    input[type="file"]
    { 
        width: 80px;        
    } 
</style>

<input id="File1" type="file" />

The problem is the width attribute that is hiding the text field will obvously vary between browsers, vary between Windows XP themes and so on. Maybe its something you can work with though?...

Try this I am also not 100 % sure

        for( int i = 0 ;i< dt.Rows.Count; i++)
        {
           If(dt.Rows[i].Product_id == 2)
           {
              dt.Rows[i].Columns["Product_name"].ColumnName = "cde";
           }
        }

That's the default margin/padding of the body element.

Some browsers have a default margin, some a default padding, and both are applied as a padding in the body element.

Add this to your CSS:

body { margin: 0; padding: 0; }

: is the delimiter of the slice syntax to 'slice out' sub-parts in sequences , [start:end]

[1:5] is equivalent to "from 1 to 5" (5 not included)
[1:] is equivalent to "1 to end"
[len(a):] is equivalent to "from length of a to end"

Watch https://youtu.be/tKTZoB2Vjuk?t=41m40s at around 40:00 he starts explaining that.

Works with tuples and strings, too.

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

Assuming the psql command-line tool, you may use \copy instead of copy.

\copy opens the file and feeds the contents to the server, whereas copy tells the server the open the file itself and read it, which may be problematic permission-wise, or even impossible if client and server run on different machines with no file sharing in-between.

Under the hood, \copy is implemented as COPY FROM stdin and accepts the same options than the server-side COPY.

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

    $ch = curl_init();

    $data = array(
        'client_id' => 'xx',
        'client_secret' => 'xx',
        'redirect_uri' => $x,
        'grant_type' => 'xxx',
        'code' => $xx,
    );

    $data = http_build_query($data);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_URL, "https://example.com");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);

    $output = curl_exec($ch);

To deserialize the response need to use HashMap:

String resp = ...//String output from your source

Gson gson = new GsonBuilder().create();
gson.fromJson(resp,TheResponse.class);

class TheResponse{
 HashMap<String,Song> songs;
}

class Song{
  String id;
  String pos;
}

I guess I am still unclear about what it is you are trying to do, but JScript.NET might be worth looking into, though Managed JScript seems like it may be more appropriate for your needs (it is more like JavaScript than JScript.NET).

Personally, I thought it would be cool to integrate V8 somehow, but I didn't get past downloading the source code; wish I had the time to actually do something with it.

the connection url for postgres syntax:

"Server=host ipaddress;Port=5432;Database=dbname;User Id=userid;Password=password;

example:

"Server=192.168.1.163;Port=5432;Database=postgres;User Id=postgres;Password=root;

For the non-selected radio buttons, flag them as disabled. This prevents them from responding to user input and clearing out the checked radio button. For example:

<input type="radio" name="var" checked="yes" value="Yes"></input>
<input type="radio" name="var" disabled="yes" value="No"></input>

Try something like the following code:

MyDAO MyDAO = new MyDAO();    
List<MyViewModel> _MyDefault = new List<MyViewModel>() {
                new MyViewModel{
                    Prop1= "All",
                    Prop2 = "Select all"
                }
            };
            ViewBag.MyViewBag= 
                new SelectList(MyDAO
                .MyList().Union(
                    _MyDefault
                    ), "Prop1", "Prop2");

I don't know if it is a solution but Invalidate Cache and Restart solved this problem in my case. I am currently using Android Studio 3.6

Try:

$("#myTable").append("<tr><%= escape_javascript( render :partial => name_of_partial ) %></tr>");

And in the partial, you should have:

<td>row1</td>
<td>row2</td>

Running this in the commandline will fix the problem also. SETX VisualStudioVersion "12.0"

try using the css pseudoclass :focus

input[type="button"], input[type="button"]:focus {

}

edit as for links and onclick events use (you shouldn’t use inline javascript eventhandlers, but for the sake of simplicity i will use them here):

<a href="some/page.php" title="perform some js action" onclick="callFunction(this.href);return false;">watch and learn</a>

with this.href you can even access the target of the link in your function. return false will just prevent browsers from following the link when clicked.

if javascript is disabled the link will work as a normal link and just load some/page.php—if you want your link to be dead when js is disabled use href="#"

from flask import request
request.headers.get('your-header-name')

request.headers behaves like a dictionary, so you can also get your header like you would with any dictionary:

request.headers['your-header-name']

Here's an easy way for Windows users.

1. Uninstall the existing codeblocks from your system.
2. Restart system.
3. Go to http://www.codeblocks.org/downloads/26
4. Download the codeblocks-16.01mingw-setup.exe file. It includes the GCC/G++ compiler and GDB debugger from TDM-GCC (version 4.9.2, 32 bit, SJLJ).

Generally it means that you are providing an index for which a list element does not exist.

E.g, if your list was [1, 3, 5, 7], and you asked for the element at index 10, you would be well out of bounds and receive an error, as only elements 0 through 3 exist.

A URL of the form https://github.com/<owner>/<project>/commit/<hash> will show you the changes introduced in that commit. For example here's a recent bugfix I made to one of my projects on GitHub:

https://github.com/jerith666/git-graph/commit/35e32b6a00dec02ae7d7c45c6b7106779a124685

You can also shorten the hash to any unique prefix, like so:

https://github.com/jerith666/git-graph/commit/35e32b

I know you just asked about GitHub, but for completeness: If you have the repository checked out, from the command line, you can achieve basically the same thing with either of these commands (unique prefixes work here too):

git show 35e32b6a00dec02ae7d7c45c6b7106779a124685
git log -p -1 35e32b6a00dec02ae7d7c45c6b7106779a124685

Note: If you shorten the commit hash too far, the command line gives you a helpful disambiguation message, but GitHub will just return a 404.

p is a pointer variable. Its value is the address of i. When you call f, you pass the value of p, which is the address of i.

I was trying to run selenium on Jenkins with Mocha framework using wdio. So following are the steps to solve this issue:-

Install google chrome

sudo apt-get update 

sudo apt-get install google-chrome-stable

Install chrome-driver

wget http://chromedriver.storage.googleapis.com/2.23/chromedriver_linux64.zip
unzip chromedriver_linux64.zip

Run following commands to start selenium web server

nohup sudo Xvfb :10 -ac
export DISPLAY=:10
java -jar vendor/se/selenium-server-standalone/bin/selenium-server-standalone.jar -Dwebdriver.chrome.bin="/usr/bin/google-chrome" -Dwebdriver.chrome.driver="vendor/bin/chromedriver"

After this start you tests with wdio command

wdio wdio.conf.js

escapeRegExp = function(str) {
  if (str == null) return '';
  return String(str).replace(/([.*+?^=!:${}()|[\]\/\\])/g, '\\$1');
};

You can do this by measuring the body size on load/resize events and setting the height to the (full height - banner height).

Note that currently in IE8 Beta2 you can't do this onresize as that event is currently broken in IE8 Beta2.

The Best Solution I found is below:

onSavedInstanceState(): always called inside fragment when activity is going to shut down(Move activity from one to another or config changes). So if we are calling multiple fragments on same activity then We have to use the following approach:

Use OnDestroyView() of the fragment and save the whole object inside that method. Then OnActivityCreated(): Check that if object is null or not(Because this method calls every time). Now restore state of an object here.

Its works always!

It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:

sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:

axs.set_ylabel('mylabel',size=6)

you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.

def set_pubfig:
    sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.

Note: If you specify these numbers, specifying font_scale in sns.set_context is ignored for all specified font elements, even if you set it.

Fix:

I chose the "ISAPI & CGI Restrictions" after clicking the server name (not the site name) in IIS Manager, and right clicked the "ASP.NET v4.0.30319" lines and chose "Allow".

After turning on ASP.NET from "Programs and Features > Turn Windows features on or off", you must install ASP.NET from the Windows command prompt. The MIME types don't ever show up, but after doing this command, I noticed these extensions showed up under the IIS web site "Handler Mappings" section of IIS Manager.

However, I still got this error. But if you do what I mentioned for the "Fix", this will go away.

HTTP Error 404.2 - Not Found
The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server.

There's no need to do this in two commits, you can add the file and mark it executable in a single commit:

C:\Temp\TestRepo>touch foo.sh

C:\Temp\TestRepo>git add foo.sh

C:\Temp\TestRepo>git ls-files --stage
100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

As you note, after adding, the mode is 0644 (ie, not executable). However, we can mark it as executable before committing:

C:\Temp\TestRepo>git update-index --chmod=+x foo.sh

C:\Temp\TestRepo>git ls-files --stage
100755 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

And now the file is mode 0755 (executable).

C:\Temp\TestRepo>git commit -m"Executable!"
[master (root-commit) 1f7a57a] Executable!
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100755 foo.sh

And now we have a single commit with a single executable file.

The following bash code will pass $file to command where $file will represent every file in /dir

for file in /dir/*
do
  cmd [option] "$file" >> results.out
done

Example

el@defiant ~/foo $ touch foo.txt bar.txt baz.txt
el@defiant ~/foo $ for i in *.txt; do echo "hello $i"; done
hello bar.txt
hello baz.txt
hello foo.txt

1. Download the latest CMake Mac binary distribution here: https://cmake.org/download/ (current latest is: https://cmake.org/files/v3.17/cmake-3.17.1-Darwin-x86_64.dmg)

2. Double click the downloaded .dmg file to install it. In the window that pops up, drag the CMake icon into the Application folder.

3. Add this line to your .bashrc file: PATH="/Applications/CMake.app/Contents/bin":"$PATH"

4. Reload your .bashrc file: source ~/.bashrc

5. Verify the latest cmake version is installed: cmake --version

6. You can launch the CMake GUI by clicking on LaunchPad and typing cmake. Click on the CMake icon that appears.

While a regexp would suit here just fine, I'll present you with an alternative method. It might be a tad faster than the equivalent regexp, but life's all about choices (...or something).

$length = strlen($urlString);
for ($i=0; $i<$length; i++) {
  if ($urlString[$i] === '?') {
    $urlString[$i+1] = '';
    break;
  }
}

Weird, I know.

You could use Jquery indeed or plain good old javascript:

var opacityPercent=30;
document.getElementById("id").style.cssText="opacity:0."+opacityPercent+"; filter:progid:DXImageTransform.Microsoft.Alpha(style=0,opacity="+opacityPercent+");";

You put this in a function that you call on a setTimeout until the desired opacity is reached

You can use .on() to bind a function to multiple events:

$('#element').on('keyup keypress blur change', function(e) {
    // e.type is the type of event fired
});

Or just pass the function as the parameter to normal event functions:

var myFunction = function() {
   ...
}

$('#element')
    .keyup(myFunction)
    .keypress(myFunction)
    .blur(myFunction)
    .change(myFunction)

• socket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• socket.getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• socket.getInetAddress().isReachable(int timeout): From isReachable(int timeout)

  Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.

You can import a csv file to this website(https://www.tablesgenerator.com/latex_tables) and click copy to clipboard.

Specify a size for the item and warehouse like in the [dbo].[testing1] FUNCTION

@trackingItems1 TABLE (
item       nvarchar(25)  NULL, -- 25 OR equal size of your item column
warehouse   nvarchar(25) NULL, -- same as above
price int   NULL

) 

Since in MSSQL only saying only nvarchar is equal to nvarchar(1) hence the values of the column from the stock table are truncated

__getitem__ can be used to implement "lazy" dict subclasses. The aim is to avoid instantiating a dictionary at once that either already has an inordinately large number of key-value pairs in existing containers, or has an expensive hashing process between existing containers of key-value pairs, or if the dictionary represents a single group of resources that are distributed over the internet.

As a simple example, suppose you have two lists, keys and values, whereby {k:v for k,v in zip(keys, values)} is the dictionary that you need, which must be made lazy for speed or efficiency purposes:

class LazyDict(dict):
    
    def __init__(self, keys, values):
        self.keys = keys
        self.values = values
        super().__init__()
        
    def __getitem__(self, key):
        if key not in self:
            try:
                i = self.keys.index(key)
                self.__setitem__(self.keys.pop(i), self.values.pop(i))
            except ValueError, IndexError:
                raise KeyError("No such key-value pair!!")
        return super().__getitem__(key)

Usage:

>>> a = [1,2,3,4]
>>> b = [1,2,2,3]
>>> c = LazyDict(a,b)
>>> c[1]
1
>>> c[4]
3
>>> c[2]
2
>>> c[3]
2
>>> d = LazyDict(a,b)
>>> d.items()
dict_items([])

practical usage:

public string someFunctionThatMayBeCalledWithNullAndReturnsString(int? value)
{
  if (value == null)
  {
    return "bad value";
  }

  return someFunctionThatHandlesIntAndReturnsString(value);
}

Simply setting proxy environment variables did not help me in version 1.0.1... I had to update the /etc/default/docker.io file with the correct value for the "http_proxy" variable.

One 'elegant' solution would be to use full text search: http://www.postgresql.org/docs/9.0/interactive/textsearch.html. Then you would use full text search queries.

 @{int i = 0;}
 @foreach(var myItem in Model.Members)
 {
     <span>@i</span>
     @{i++;
      }
 }

// Use @{i++ to increment value}

To access a single value you can use the method iat that is much faster than iloc:

df['Btime'].iat[0]

Output:

1.2

You can only return from inside a function and not from a loop.

It seems like your return should be outside the while loop, and your complete code should be inside a function.

def func():
    N = int(input("enter a positive integer:"))
    counter = 1
    while (N > 0):
        counter = counter * N
        N -= 1
    return counter  # de-indent this 4 spaces to the left.

print func()

And if those codes are not inside a function, then you don't need a return at all. Just print the value of counter outside the while loop.

Based on Olivier Refalo's answer

if [ $# -eq 2 ] 
then
    echo "Setting tracking for branch " $1 " -> " $2
    git branch --set-upstream $1 $2
else
    echo "-- Local --" 
    git for-each-ref --shell --format="[ %(upstream:short) != '' ] && echo -e '\t%(refname:short) <--> %(upstream:short)'" refs/heads | sh
    echo "-- Remote --" 
    REMOTES=$(git remote -v) 
    if [ "$REMOTES" != '' ]
    then
        echo $REMOTES
    fi  
fi

It shows only local with track configured.

Write it on a script called git-track on your path an you will get a git track command

Add gesture on that view. Add an image into that view, and then it would be detecting a gesture on the image too. You could try with the delegate method of the touch event. Then in that case it also might be detecting.

I understand this question might have a React-specific cause, but it shows up first in search results for "Typeerror: Failed to fetch" and I wanted to lay out all possible causes here.

The Fetch spec lists times when you throw a TypeError from the Fetch API: https://fetch.spec.whatwg.org/#fetch-api

Relevant passages as of January 2021 are below. These are excerpts from the text.

4.6 HTTP-network fetch

To perform an HTTP-network fetch using request with an optional credentials flag, run these steps:
...
16. Run these steps in parallel:
...
2. If aborted, then:
...
3. Otherwise, if stream is readable, error stream with a TypeError.

To append a name/value name/value pair to a Headers object (headers), run these steps:

1. Normalize value.
2. If name is not a name or value is not a value, then throw a TypeError.
3. If headers’s guard is "immutable", then throw a TypeError.

Filling Headers object headers with a given object object:

To fill a Headers object headers with a given object object, run these steps:

1. If object is a sequence, then for each header in object:
   1. If header does not contain exactly two items, then throw a TypeError.

Method steps sometimes throw TypeError:

The delete(name) method steps are:

1. If name is not a name, then throw a TypeError.
2. If this’s guard is "immutable", then throw a TypeError.

The get(name) method steps are:

1. If name is not a name, then throw a TypeError.
2. Return the result of getting name from this’s header list.

The has(name) method steps are:

1. If name is not a name, then throw a TypeError.

The set(name, value) method steps are:

1. Normalize value.
2. If name is not a name or value is not a value, then throw a TypeError.
3. If this’s guard is "immutable", then throw a TypeError.

To extract a body and a Content-Type value from object, with an optional boolean keepalive (default false), run these steps:
...
5. Switch on object:
...
ReadableStream
If keepalive is true, then throw a TypeError.
If object is disturbed or locked, then throw a TypeError.

In the section "Body mixin" if you are using FormData there are several ways to throw a TypeError. I haven't listed them here because it would make this answer very long. Relevant passages: https://fetch.spec.whatwg.org/#body-mixin

In the section "Request Class" the new Request(input, init) constructor is a minefield of potential TypeErrors:

The new Request(input, init) constructor steps are:
...
6. If input is a string, then:
...
2. If parsedURL is a failure, then throw a TypeError.
3. IF parsedURL includes credentials, then throw a TypeError.
...
11. If init["window"] exists and is non-null, then throw a TypeError.
...
15. If init["referrer" exists, then:
...
1. Let referrer be init["referrer"].
2. If referrer is the empty string, then set request’s referrer to "no-referrer".
3. Otherwise:
1. Let parsedReferrer be the result of parsing referrer with baseURL.
2. If parsedReferrer is failure, then throw a TypeError.
...
18. If mode is "navigate", then throw a TypeError.
...
23. If request's cache mode is "only-if-cached" and request's mode is not "same-origin" then throw a TypeError.
...
27. If init["method"] exists, then:
...
2. If method is not a method or method is a forbidden method, then throw a TypeError.
...
32. If this’s request’s mode is "no-cors", then:
1. If this’s request’s method is not a CORS-safelisted method, then throw a TypeError.
...
35. If either init["body"] exists and is non-null or inputBody is non-null, and request’s method is GET or HEAD, then throw a TypeError.
...
38. If body is non-null and body's source is null, then:
1. If this’s request’s mode is neither "same-origin" nor "cors", then throw a TypeError.
...
39. If inputBody is body and input is disturbed or locked, then throw a TypeError.

The clone() method steps are:

1. If this is disturbed or locked, then throw a TypeError.

In the Response class:

The new Response(body, init) constructor steps are:
...
2. If init["statusText"] does not match the reason-phrase token production, then throw a TypeError.
...
8. If body is non-null, then:
1. If init["status"] is a null body status, then throw a TypeError.
...

The static redirect(url, status) method steps are:
...
2. If parsedURL is failure, then throw a TypeError.

The clone() method steps are:

1. If this is disturbed or locked, then throw a TypeError.

In section "The Fetch method"

The fetch(input, init) method steps are:
...
9. Run the following in parallel:
To process response for response, run these substeps:
...
3. If response is a network error, then reject p with a TypeError and terminate these substeps.

In addition to these potential problems, there are some browser-specific behaviors which can throw a TypeError. For instance, if you set keepalive to true and have a payload > 64 KB you'll get a TypeError on Chrome, but the same request can work in Firefox. These behaviors aren't documented in the spec, but you can find information about them by Googling for limitations for each option you're setting in fetch.

Consider an example having 10 apples. When it implements Iterable, it is like putting each apple in boxes from 1 to 10 and return an iterator which can be used to navigate.

By implementing iterator, we can get any apple, apple in next boxes etc.

So implementing iterable gives an iterator to navigate its elements although to navigate, iterator needs to be implemented.

The userid where the commit happens is stored in the config file.

go to the top of the repository vi .git/config

change the url line listed after "[remote "origin"] to have the appropriate userid

FrameLayout is not the better way to do this:

Use RelativeLayout instead. You can position the elements anywhere you like. The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).

Example:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimary"
        app:srcCompat="@drawable/ic_information"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is a text."
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="8dp"
        android:padding="5dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:background="#A000"
        android:textColor="@android:color/white"/>
</RelativeLayout>

In your example problem is passed table name pattern in getTables function of DatabaseMetaData.

Some database supports Uppercase identifier, some support lower case identifiers. For example oracle fetches the table name in upper case, while postgreSQL fetch it in lower case.

DatabaseMetaDeta provides a method to determine how the database stores identifiers, can be mixed case, uppercase, lowercase see:http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#storesMixedCaseIdentifiers()

From below example, you can get all tables and view of providing table name pattern, if you want only tables then remove "VIEW" from TYPES array.

public class DBUtility {
    private static final String[] TYPES = {"TABLE", "VIEW"};
    public static void getTableMetadata(Connection jdbcConnection, String tableNamePattern, String schema, String catalog, boolean isQuoted) throws HibernateException {
            try {
                DatabaseMetaData meta = jdbcConnection.getMetaData();
                ResultSet rs = null;
                try {
                    if ( (isQuoted && meta.storesMixedCaseQuotedIdentifiers())) {
                        rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
                    } else if ( (isQuoted && meta.storesUpperCaseQuotedIdentifiers())
                        || (!isQuoted && meta.storesUpperCaseIdentifiers() )) {
                        rs = meta.getTables(
                                StringHelper.toUpperCase(catalog),
                                StringHelper.toUpperCase(schema),
                                StringHelper.toUpperCase(tableNamePattern),
                                TYPES
                            );
                    }
                    else if ( (isQuoted && meta.storesLowerCaseQuotedIdentifiers())
                            || (!isQuoted && meta.storesLowerCaseIdentifiers() )) {
                        rs = meta.getTables( 
                                StringHelper.toLowerCase( catalog ),
                                StringHelper.toLowerCase(schema), 
                                StringHelper.toLowerCase(tableNamePattern), 
                                TYPES 
                            );
                    }
                    else {
                        rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
                    }

                    while ( rs.next() ) {
                        String tableName = rs.getString("TABLE_NAME");
                        System.out.println("table = " + tableName);
                    }



                }
                finally {
                    if (rs!=null) rs.close();
                }
            }
            catch (SQLException sqlException) {
                // TODO 
                sqlException.printStackTrace();
            }

    }

            e.printStackTrace();

}

The actual problem of this error has nothing to do with file_get_content, the problem is the requested url if the url is not throwing content of the page and redirecting the request to some where else file_get_content says "Failed to open stream", just before file_get_contents check whether the url is working and not redirecting, here is the code:

function checkRedirect404($url) {

$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_URL, $url);
    $out = curl_exec($ch);

    // line endings is the wonkiest piece of this whole thing
    $out = str_replace("\r", "", $out);

    // only look at the headers
    $headers_end = strpos($out, "\n\n");
    if( $headers_end !== false ) { 
        $out = substr($out, 0, $headers_end);
    }   

    $headers = explode("\n", $out);
    foreach($headers as $header) {
        if( substr($header, 0, 10) == "Location: " ) { 
            $target = substr($header, 10);

            //echo "Redirects: $target<br>";

            return true;
        }   
    }   

    return false;

}

This should work:

SELECT model, date FROM doc GROUP BY model ORDER BY date DESC

It just sort the dates from last to first and by grouping it only grabs the first one.

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

We wanted to use the elegant solution up there using angularjs material but it didnt work because there are actually no option / md-option tags in the DOM until the md-select has been clicked. So the "elegant" way didn't work for us (note angular material!) Here is what we did for it instead, don't know if its the best way but its definately working now

element.all(by.css('md-select')).each(function (eachElement, index) {
    eachElement.click();                    // select the <select>
    browser.driver.sleep(500);              // wait for the renderings to take effect
    element(by.css('md-option')).click();   // select the first md-option
    browser.driver.sleep(500);              // wait for the renderings to take effect
});

We needed to have 4 selects selected and while the select is open, there is an overlay in the way of selecting the next select. thats why we need to wait 500ms to make sure we don't get into trouble with the material effects still being in action.

break is to break out of a loop like for, while, switch etc which you don't have here, you need to use return to break the execution flow of the current function and return to the caller.

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        requestAnimFrame(loop);
        if (game == 1) {
           return
        }
    }
}

Note: This does not cover the logic behind the if condition or when to return from the method, for that we need to have more context regarding the drawAllEnemies and requestAnimFrame method as well as how game value is updated

I managed to get FTP access to the customer's server and so was able to track down the problem.

After the form is POSTed, I authenticate the user and then redirect to the main part of the app.

Util::redirect('/apps/content');

The error was occurring not on the posting of the form, but on the redirect immediately following it. For some reason, IIS was continuing to presume the POST method for the redirect, and then objecting to the POST to /apps/content as it's a directory.

The error message never indicated that it was the following page that was generating the error - thanks Microsoft!

The solution was to add a trailing slash:

Util::redirect('/apps/content/');

IIS could then resolve the redirect to a default document as is no longer attempting to POST to a directory.

With React 16.6.3 and @Material UI 3.5.1, I am using arrays in className like className={[classes.tableCell, classes.capitalize]}

Try something like the following in your case.

class Pill extends React.Component {
    render() {
        return (
           <button className={['pill', this.props.styleName]}>{this.props.children}</button>
        );
    }
}

For those of you that have Postgres 9.5 or higher, the new ON CONFLICT DO NOTHING syntax should work:

INSERT INTO target_table (field_one, field_two, field_three ) 
SELECT field_one, field_two, field_three
FROM source_table
ON CONFLICT (field_one) DO NOTHING;

For those of us who have an earlier version, this right join will work instead:

INSERT INTO target_table (field_one, field_two, field_three )
SELECT source_table.field_one, source_table.field_two, source_table.field_three
FROM source_table 
LEFT JOIN target_table ON source_table.field_one = target_table.field_one
WHERE target_table.field_one IS NULL;

This is how I fixed it. in Visual Studio Code's terminal, First cache clean

npm cache clean --force

Then updated cli

ng update @angular/cli

If any module missing after this, use below command

npm install

If you're using .Net 4 you can use the overload for string.Join that takes an IEnumerable if you have them in a List, too:

string.Join(", ", strings);

I don't think there isn't any need to check if the number is negative.

A simple function to find the positive modulo would be this -

Edit: Assuming N > 0 and N + N - 1 <= INT_MAX

int modulo(int x,int N){
    return (x % N + N) %N;
}

This will work for both positive and negative values of x.

Original P.S: also as pointed out by @chux, If your x and N may reach something like INT_MAX-1 and INT_MAX respectively, just replace int with long long int.

And If they are crossing limits of long long as well (i.e. near LLONG_MAX), then you shall handle positive and negative cases separately as described in other answers here.

The posttitle part of the URL is after your index.php file, which is a common way of providing friendly URLs without using mod_rewrite. The posttitle is actually therefore part of the query string, so you should be able to get it using $_SERVER['QUERY_STRING']

cURL-less you can use in php5

$url = 'URL';
$data = array('field1' => 'value', 'field2' => 'value');
$options = array(
        'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data),
    )
);

$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);

Here is the arguments parser. You can mix any string arguments (kept untouched) or escaped options (single or option/value pairs). To test it uncomment last 2 statements and run as:

getargs anystr1 anystr2 /test$1 /test$2=123 /test$3 str anystr3

Escape char is defined as "_SEP_=/", redefine if needed.

@echo off

REM Command line argument parser. Format (both "=" and "space" separators are supported):

Using leech's answer with indexOf (to support IE)

This is using what leech talked about, but making it work for IE (IE doesn't support matches):

function closest(el, selector, stopSelector) {
  var retval = null;
  while (el) {
    if (el.className.indexOf(selector) > -1) {
      retval = el;
      break
    } else if (stopSelector && el.className.indexOf(stopSelector) > -1) {
      break
    }
    el = el.parentElement;
  }
  return retval;
}

It's not perfect, but it works if the selector is unique enough so it won't accidentally match the incorrect element.

In my case, here is the steps.

Step-1

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Here notify the fragment that it should participate in options menu handling.
    setHasOptionsMenu(true);
}

Step-2

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // First clear current all the menu items
    menu.clear();

    // Add the new menu items
    inflater.inflate(R.menu.post_stuff, menu);

    super.onCreateOptionsMenu(menu, inflater);
}

Step-3

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.post_stuff:
            Log.d(TAG, "Will post the photo to server");
            return true;
        case R.id.cancel_post:
            Log.d(TAG, "Will cancel post the photo");
            return true;
        default:
            break;
    }
    return super.onOptionsItemSelected(item);
}

You can add an auto generated id field in the table and select by this id

SELECT * FROM CUSTOMER WHERE CUSTOMER_ID = 3;

step 1: Enter into the MongoDB shell.

mongo

step 2: for the display all the databases.

show dbs;

step 3: for a select database :

use 'databases_name'

step 4: for statistics of your database.

db.stats()

step 5: listing out all the collections(tables).

show collections

step 6:print the data from a particular collection.

db.'collection_name'.find().pretty()

Use this:

DateTime dateTime =  DateTime.Now;
DateTime? newDateTime = null;
TimeSpan numberOfDays = new TimeSpan(2, 0, 0, 0, 0);
newDateTime = dateTime.Add(numberOfDays);

1. Change the TIME_ZONE to your local time zone, and keep USE_TZ as True in 'setting.py':

   TIME_ZONE = 'Asia/Shanghai'

   USE_I18N = True

   USE_L10N = True

   USE_TZ = True

2. This will write and store the datetime object as UTC to the backend database.

3. Then use template tag to convert the UTC time in your frontend template as such:

               <td> 
                   {% load tz %}
                   {% get_current_timezone as tz %}
                   {% timezone tz %}
                       {{ message.log_date | time:'H:i:s' }}
                   {% endtimezone %} 
               </td>
   

or use the template filters concisely:

                <td> 
                    {% load tz %}
                    {{ message.log_date | localtime | time:'H:i:s' }}
                </td>

4. You could check more details in the official doc: Default time zone and current time zone

   When support for time zones is enabled, Django stores datetime information in UTC in the database, uses time-zone-aware datetime objects internally, and translates them to the end user’s time zone in templates and forms.

You have to put your main queue dispatching in the block that runs the computation. For example (here I create a dispatch queue and don't use a global one):

dispatch_queue_t queue = dispatch_queue_create("com.example.MyQueue", NULL);
dispatch_async(queue, ^{
  // Do some computation here.

  // Update UI after computation.
  dispatch_async(dispatch_get_main_queue(), ^{
    // Update the UI on the main thread.
  });
});

Of course, if you create a queue don't forget to dispatch_release if you're targeting an iOS version before 6.0.

Try this

$("#message span").text("hello world!");

function Errormessage(txt) {
    var elem = $("#message");
    elem.fadeIn("slow");
    // find the span inside the div and assign a text
    elem.children("span").text("your text");

    elem.children("a.close-notify").click(function() {
        elem.fadeOut("slow");
    });
}

Instead of if-else condition use if in both conditions. it will work that way but not sure why.

In Windows 7 Path Environment Variables I just add at the end of System Variable path

\;C:\Program Files\Git\bin

and it works now!

I don't think the jar tool supports this natively, but you can just unzip a JAR file with "unzip" and specify the output directory with that with the "-d" option, so something like:

$ unzip -d /home/foo/bar/baz /home/foo/bar/Portal.ear Binaries.war

I'm torn between these two ways of implementing an index of a NumPy array:

idx = list(classes).index(var)
idx = np.where(classes == var)

Both take the same number of characters, but the first method returns an int instead of a numpy.ndarray.

    var str = 'Hello World';
                str = setCharAt(str, 3, '');
                alert(str);

function setCharAt(str, index, chr)
        {
            if (index > str.length - 1) return str;
            return str.substr(0, index) + chr + str.substr(index + 1);
        }

This is because label is an inline element, and is therefore only as big as the text it contains.

The possible is to display your label as a block element like this:

#formItem label {
    display: block;
    text-align: center;
    line-height: 150%;
    font-size: .85em;
}

However, if you want to use the label on the same line with other elements, you either need to set display: inline-block; and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div and do the alignment in the div.

temp = bankAccNos.contains(no) ? 1 : 2;

Just adding this answer. "Stroking" the text is not the same as "Outlining"

Outlining looks great. Stroking looks horrid.

The SVG solution listed elsewhere has the same issue. Of you want an outline you need to put the text twice. Once stroked and again not stroked.

Stroking IS NOT Outlining

PS: I'd love to know how to make the SVG be the correct size of any arbitrary text. I have a feeling it's fairly complicated involving generating the svg, querying it with javascript to get the extents then applying the results. If there is an easier non-js way I'd love to know.

This happened to me recently. I was fully migrate to MySQL 5.7, and everything is in default configuration.

All previously answers are already clear and I just want to add something.

This 1406 error could happen in your function / procedure too and not only to your table's column length.

In my case, I've trigger which call procedure with IN parameter varchar(16) but received 32 length value.

I hope this help someone with similar problem.

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

Try using RUN /bin/sh instead of bash.

Works finde for me:

$dom = new \DOMDocument;
$dom->loadHTML(utf8_decode($html));
...
return  utf8_encode( $dom->saveHTML());

Well actually you will need to return something like this because toString has to return a string

public String toString() {
 return "Name :" + this.name + "whatever :" + this.whatever + "";
}

and you actually do something wrong in the constructer you set the variable the user set to the name while you need to do the opposite. What you shouldn't do

n = this.name

What you should do

this.name = n

Hopes this helps thanks

public static void main(String[] args) {
    int[] toyNumber = new int[] {5};
    NewClass temp = new NewClass();
    temp.play(toyNumber);
    System.out.println("Toy number in main " + toyNumber[0]);
}

void play(int[] toyNumber){
    System.out.println("Toy number in play " + toyNumber[0]);
    toyNumber[0]++;
    System.out.println("Toy number in play after increement " + toyNumber[0]);
}

I also wanted to do this, but with a method that receives a BOOL parameter. Wrapping the bool value with NSNumber, FAILED TO PASS THE VALUE. I have no idea why.

So I ended up doing a simple hack. I put the required parameter in another dummy function and call that function using the performSelector, where withObject = nil;

[self performSelector:@selector(dummyCaller:) withObject:nil afterDelay:5.0];

-(void)dummyCaller {

[self myFunction:YES];

modern.IE is an undertaking by Microsoft to make cross-browser testing for the Internet Explorer browsers easier. Microsoft has created modern.IE to provide developers and designers with a suite of tools to facilitate IE browser testing.

With modern.IE you have two methods of testing your website in IE. First, modern.IE offers you three months free usage of the web-based browser testing service BrowserStack. You just need a Facebook account to login and start testing.

The second method modern.IE offers is a virtualization image of each browser from IE 6 to IE 10, which can be run on virtualization software like VirtualBox, Virtual PC, Hyper-V or VMWare Player on WIndows, Mac or Linux.

Additionally, modern.IE also provides a tool which scans your web page for common coding problems and lists them out for you to correct so that they display correctly in all IE versions.

            $enddate=date('Y', strtotime($endate));  

            $years = range ($stdate,$enddate);
            echo '<select name="years" class="form-control">';
            echo '<option>SELECT</option>';
            foreach($years as $year)
              {   echo '<option value="'.$year.'"> '.$year.' </option>';  }
                echo '</select>'; ?>

In order to deploy your Angular2 app to a production server, first and foremost, ensure your app runs locally on your machine.

Angular2 app can also be deployed as a node app.

So, create a node entry point file server.js/app.js (my example uses express)

var express = require('express'),
    path = require('path'),
    fs = require('fs');

var app = express();
var staticRoot = __dirname + '/';

app.set('port', (process.env.PORT || 3000));

app.use(express.static(staticRoot));

app.use(function(req, res, next){

    // if the request is not html then move along
    var accept = req.accepts('html', 'json', 'xml');
    if(accept !== 'html'){
        return next();
    }

    // if the request has a '.' assume that it's for a file, move along
    var ext = path.extname(req.path);
    if (ext !== ''){
        return next();
    }

    fs.createReadStream(staticRoot + 'index.html').pipe(res);

}); 

app.listen(app.get('port'), function() {
    console.log('app running on port', app.get('port'));
});

Also add express as a dependency in your package.json file.

Then deploy it on your preferred environment.

I have put together a small blog for deployment on IIS. follow link

In my Case, it is because of having more than one connection string in your Solution. one for your current project and the other one for a startup project in your Solution. for more information please refer to Telerik report not working

here we have the same situation.

At the risk of causing some cringing by purests and c# programmers, you can use multiple statements and else in a one-line if statement in VB. In this example, y ends up 3 and not 7.

i = 1
If i = 1 Then x = 3 : y = 3 Else x = 7 : y = 7

Friend functions and classes provide direct access to private and protected members of class to avoid breaking encapsulation in the general case. Most usage is with ostream: we would like to be able to type:

Point p;
cout << p;

However, this may require access to the private data of Point, so we define the overloaded operator

friend ostream& operator<<(ostream& output, const Point& p);

There are obvious encapsulation implications, however. First, now the friend class or function has full access to ALL members of the class, even ones that do not pertain to its needs. Second, the implementations of the class and the friend are now enmeshed to the point where an internal change in the class can break the friend.

If you view the friend as an extension of the class, then this is not an issue, logically speaking. But, in that case, why was it necessary to spearate out the friend in the first place.

To achieve the same thing that 'friends' purport to achieve, but without breaking encapsulation, one can do this:

class A
{
public:
    void need_your_data(B & myBuddy)
    {
        myBuddy.take_this_name(name_);
    }
private:
    string name_;
};

class B
{
public:
    void print_buddy_name(A & myBuddy)
    {
        myBuddy.need_your_data(*this);
    }
    void take_this_name(const string & name)
    {
        cout << name;
    }
}; 

Encapsulation is not broken, class B has no access to the internal implementation in A, yet the result is the same as if we had declared B a friend of A. The compiler will optimize away the function calls, so this will result in the same instructions as direct access.

I think using 'friend' is simply a shortcut with arguable benefit, but definite cost.

On a German keyboard it's ctrl+shift+^.

If using inline-blocks is an option I would recommend this approach:

.container { 
    /* fixed position a zero-height full width container */
    position: fixed;
    top: 0; /* or whatever position is desired */
    left: 0;
    right: 0;
    height: 0;
    /* center all inline content */
    text-align: center;
}

.container > div {
    /* make the block inline */
    display: inline-block;
    /* reset container's center alignment */
    text-align: left;
} 

I wrote a short post on this here: http://salomvary.github.com/position-fixed-horizontally-centered.html

Here is a Python module providing API's to get data from IMDB website

http://techdiary-viki.blogspot.com/2011/03/imdb-api.html

There are a few places you can do versioning in a REST API:

1. As noted, in the URI. This can be tractable and even esthetically pleasing if redirects and the like are used well.

2. In the Accepts: header, so the version is in the filetype. Like 'mp3' vs 'mp4'. This will also work, though IMO it works a bit less nicely than...

3. In the resource itself. Many file formats have their version numbers embedded in them, typically in the header; this allows newer software to 'just work' by understanding all existing versions of the filetype while older software can punt if an unsupported (newer) version is specified. In the context of a REST API, it means that your URIs never have to change, just your response to the particular version of data you were handed.

I can see reasons to use all three approaches:

1. if you like doing 'clean sweep' new APIs, or for major version changes where you want such an approach.
2. if you want the client to know before it does a PUT/POST whether it's going to work or not.
3. if it's okay if the client has to do its PUT/POST to find out if it's going to work.

Good answers above- if you're looking for something reusable here is the code. Note that you might want to check the decimal places value, and this may overflow.

public static decimal TruncateToDecimalPlace(this decimal numberToTruncate, int decimalPlaces)
{
    decimal power = (decimal)(Math.Pow(10.0, (double)decimalPlaces));

    return Math.Truncate((power * numberToTruncate)) / power;
}

I was annoyed that you had to always include the namespace and the folder in the string. I wanted to simplify the access to the embedded resources. This is why I wrote this little class. Feel free to use and improve!

Usage:

using(Stream stream = EmbeddedResources.ExecutingResources.GetStream("filename.txt"))
{
 //...
}

Class:

public class EmbeddedResources
{
    private static readonly Lazy<EmbeddedResources> _callingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetCallingAssembly()));

    private static readonly Lazy<EmbeddedResources> _entryResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetEntryAssembly()));

    private static readonly Lazy<EmbeddedResources> _executingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetExecutingAssembly()));

    private readonly Assembly _assembly;

    private readonly string[] _resources;

    public EmbeddedResources(Assembly assembly)
    {
        _assembly = assembly;
        _resources = assembly.GetManifestResourceNames();
    }

    public static EmbeddedResources CallingResources => _callingResources.Value;

    public static EmbeddedResources EntryResources => _entryResources.Value;

    public static EmbeddedResources ExecutingResources => _executingResources.Value;

    public Stream GetStream(string resName) => _assembly.GetManifestResourceStream(_resources.Single(s => s.Contains(resName)));

}

In case of Oracle since 12c you have DEFAULT ON NULL which implies a NOT NULL constraint.

ALTER TABLE tbl ADD (col VARCHAR(20) DEFAULT ON NULL 'MyDefault');

ALTER TABLE

ON NULL

If you specify the ON NULL clause, then Oracle Database assigns the DEFAULT column value when a subsequent INSERT statement attempts to assign a value that evaluates to NULL.

When you specify ON NULL, the NOT NULL constraint and NOT DEFERRABLE constraint state are implicitly specified. If you specify an inline constraint that conflicts with NOT NULL and NOT DEFERRABLE, then an error is raised.

Using C++ in MS Visual Studio 2015 (14), I use:

#include <chrono>

string NowToString()
{
  chrono::system_clock::time_point p = chrono::system_clock::now();
  time_t t = chrono::system_clock::to_time_t(p);
  char str[26];
  ctime_s(str, sizeof str, &t);
  return str;
}

I happened to encounter a similar kind of issue after setting up local internal JFrog Docker Private Registry on Amazon Linux.

THE followings I did to solve the issue:

Added "--insecure-registry xx.xx.xx.xx:8081" by modifying the OPTIONS variable in the /etc/sysconfig/docker file:

OPTIONS="--default-ulimit nofile=1024:40961 --insecure-registry hostname:8081"

Then restarted the docker.

I was then able to login to the local docker registry using:

docker login -u admin -p password hostname:8081

What's perplexing to me is that the visual studio designer only allows you to use BackgroundWorkers and Timers that don't actually work with the service project.

It gives you neat drag and drop controls onto your service but... don't even try deploying it. Won't work.

Services: Only use System.Timers.Timer System.Windows.Forms.Timer won't work even though it's available in the toolbox

Services: BackgroundWorkers will not work when it's running as a service Use System.Threading.ThreadPools instead or Async calls

How to import CSV file data into a PostgreSQL table?

steps:

1. Need to connect postgresql database in terminal

   psql -U postgres -h localhost
   

2. Need to create database

   create database mydb;
   

3. Need to create user

   create user siva with password 'mypass';
   

4. Connect with database

   \c mydb;
   

5. Need to create schema

   create schema trip;
   

6. Need to create table

   create table trip.test(VendorID int,passenger_count int,trip_distance decimal,RatecodeID int,store_and_fwd_flag varchar,PULocationID int,DOLocationID int,payment_type decimal,fare_amount decimal,extra decimal,mta_tax decimal,tip_amount decimal,tolls_amount int,improvement_surcharge decimal,total_amount
   );
   

7. Import csv file data to postgresql

   COPY trip.test(VendorID int,passenger_count int,trip_distance decimal,RatecodeID int,store_and_fwd_flag varchar,PULocationID int,DOLocationID int,payment_type decimal,fare_amount decimal,extra decimal,mta_tax decimal,tip_amount decimal,tolls_amount int,improvement_surcharge decimal,total_amount) FROM '/home/Documents/trip.csv' DELIMITER ',' CSV HEADER;
   

8. Find the given table data

   select * from trip.test;
   

Using a shebang line to invoke the appropriate interpreter is not just for BASH. You can use the shebang for any interpreted language on your system such as Perl, Python, PHP (CLI) and many others. By the way, the shebang

#!/bin/sh -

(it can also be two dashes, i.e. --) ends bash options everything after will be treated as filenames and arguments.

Using the env command makes your script portable and allows you to setup custom environments for your script hence portable scripts should use

#!/usr/bin/env bash

Or for whatever the language such as for Perl

#!/usr/bin/env perl

Be sure to look at the man pages for bash:

man bash

and env:

man env

Note: On Debian and Debian-based systems, like Ubuntu, sh is linked to dash not bash. As all system scripts use sh. This allows bash to grow and the system to stay stable, according to Debian.

Also, to keep invocation *nix like I never use file extensions on shebang invoked scripts, as you cannot omit the extension on invocation on executables as you can on Windows. The file command can identify it as a script.

Just as an FYI, you can also specify those things as column attributes. For instance, I might have done:

.order_by(model.Entry.amount.desc())

This is handy since it avoids an import, and you can use it on other places such as in a relation definition, etc.

For more information, you can refer this

$(document).ready(function(){     
$("div.width").append($("div.width").width()+" px");
$("div.innerWidth").append($("div.innerWidth").innerWidth()+" px");   
$("div.outerWidth").append($("div.outerWidth").outerWidth()+" px");         
});


<div class="width">Width of this div container without including padding is: </div>  
<div class="innerWidth">width of this div container including padding is: </div> 
<div class="outerWidth">width of this div container including padding and margin is:     </div>

Another possibility is to set the app:actionViewClass attribute in your menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto">
  <item
     android:id="@+id/get_item"
     android:orderInCategory="1"
     android:text="Get"
     app:showAsAction="always" 
     app:actionViewClass="android.support.v7.widget.AppCompatButton"/>
</menu>

In your code you can access this button after the menu was inflated:

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.sample, menu);

    MenuItem getItem = menu.findItem(R.id.get_item);
    if (getItem != null) {
        AppCompatButton button = (AppCompatButton) getItem.getActionView();
        //Set a ClickListener, the text, 
        //the background color or something like that
    }

    return super.onCreateOptionsMenu(menu);
}

Java Primitive Specializations Generator supports /* with */, /* define */ and /* if */ ... /* elif */ ... /* endif */ blocks which allow to do some kind of macro generation in Java code, similar to java-comment-preprocessor mentioned in this answer.

JPSG has Maven and Gradle plugins.

As an addition to the answer by marc_s, you can use a more generic extension method to get values from the SqlDataReader:

public static T SafeGet<T>(this SqlDataReader reader, int col)
    {
        return reader.IsDBNull(col) ? default(T) : reader.GetFieldValue<T>(col);
    }

Sometimes this can refer to another scope and refer to something else, for example suppose you want to call a constructor method inside a DOM event, in this case this will refer to the DOM element not the created object.

HTML

<button id="button">Alert Name</button>

JS

var Person = function(name) {
  this.name = name;
  var that = this;
  this.sayHi = function() {
    alert(that.name);
  };
};

var ahmad = new Person('Ahmad');
var element = document.getElementById('button');
element.addEventListener('click', ahmad.sayHi); // => Ahmad

Demo

The solution above will assing this to that then we can and access the name property inside the sayHi method from that, so this can be called without issues inside the DOM call.

Another solution is to assign an empty that object and add properties and methods to it and then return it. But with this solution you lost the prototype of the constructor.

var Person = function(name) {
  var that = {};
  that.name = name;
  that.sayHi = function() {
    alert(that.name);
  };
  return that;
};

Just sharing as this was my solution thanks to Canavar's post.

If you have something like this:

"http://localhost:1234/Default.aspx?un=asdf&somethingelse=fdsa"

or like this:

"https://www.something.com/index.html?a=123&b=4567"

and you only want the part that a user would type in then this will work:

String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery;
String strUrl = HttpContext.Current.Request.Url.AbsoluteUri.Replace(strPathAndQuery, "/");

which would result in these:

"http://localhost:1234/"
"https://www.something.com/"

I think your question isn't quite clear. There are several answers here on how to catch the data coming into a Linux's serial port, but perhaps your problem is the other way around?

If you need to catch the data coming out of a Linux's serial port and send it to a server, there are several little hardware gizmos that can do this, starting with the simple serial print server such as this Lantronix gizmo.

No, I'm not affiliated with Lantronix in any way.

You may also consider the Apache Commons JCI (Java Compiler Interface). Although this API seems to be focused on dynamic compilation of classes, it also includes classes in its API that monitors file changes.

Example: http://commons.apache.org/jci/usage.html

This was the only reasonable thing I found to fade a background image.

<div id="foo">
  <!-- some content here -->
</div>

Your CSS; now enhanced with CSS3 transition.

#foo {
  background-image: url(a.jpg);
  transition: background 1s linear;
}

Now swap out the background

document.getElementById("foo").style.backgroundImage = "url(b.jpg)";

Voilà, it fades!

Obvious disclaimer: if your browser doesn't support the CSS3 transition property, this won't work. In which case, the image will change without a transition. Given <1% of your users' browser don't support CSS3, that's probably fine. Don't kid yourself, it's fine.

These days even if the spec doesn't allow it, it "seems" to still work to embed the button within a <a href...><button ...></a> tag, FWIW...

From Apple Docs (Swift 3.0.1),

You can simply use a static type property, which is guaranteed to be lazily initialized only once, even when accessed across multiple threads simultaneously:

class Singleton {
    static let sharedInstance = Singleton()
}

If you need to perform additional setup beyond initialization, you can assign the result of the invocation of a closure to the global constant:

class Singleton {
    static let sharedInstance: Singleton = {
        let instance = Singleton()
        // setup code
        return instance
    }()
}

Basically indexOf() is a method belongs to string(array object also), But while calling the function you are passing a number, try to cast it to a string and pass it.

document.getElementById("oset").innerHTML = timeD2C(timeofday + "");

 var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;_x000D_
_x000D_
_x000D_
_x000D_
_x000D_
 function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)_x000D_
    var pos = time.indexOf('.');_x000D_
    var hrs = time.substr(1, pos - 1);_x000D_
    var min = (time.substr(pos, 2)) * 60;_x000D_
_x000D_
    if (hrs > 11) {_x000D_
        hrs = (hrs - 12) + ":" + min + " PM";_x000D_
    } else {_x000D_
        hrs += ":" + min + " AM";_x000D_
    }_x000D_
    return hrs;_x000D_
}_x000D_
alert(timeD2C(timeofday+""));

And it is good to do the string conversion inside your function definition,

function timeD2C(time) { 
  time = time + "";
  var pos = time.indexOf('.');

So that the code flow won't break at times when devs forget to pass a string into this function.

you can use position:relative; inside #one div and position:absolute inside #two div. you can see it

You have to execute your query and add single quote to $email in the query beacuse it's a string, and remove the is_resource($query) $query is a string, the $result will be the resource

$query = "SELECT `email` FROM `tblUser` WHERE `email` = '$email'";
$result = mysqli_query($link,$query); //$link is the connection

if(mysqli_num_rows($result) > 0 ){....}

UPDATE

Base in your edit just change:

if(is_resource($query) && mysqli_num_rows($query) > 0 ){
        $query = mysqli_fetch_assoc($query);
        echo $email . " email exists " .  $query["email"] . "\n";

By

if(is_resource($result) && mysqli_num_rows($result) == 1 ){
        $row = mysqli_fetch_assoc($result);
         echo $email . " email exists " .  $row["email"] . "\n";

and you will be fine

UPDATE 2

A better way should be have a Store Procedure that execute the following SQL passing the Email as Parameter

SELECT IF( EXISTS (
                  SELECT *
                  FROM `Table`
                  WHERE `email` = @Email)
          , 1, 0) as `Exist`

and retrieve the value in php

Pseudocodigo:

 $query = Call MYSQL_SP($EMAIL);
 $result = mysqli_query($conn,$query);
 $row = mysqli_fetch_array($result)
 $exist = ($row['Exist']==1)? 'the email exist' : 'the email doesnt exist';

You can use the .some method referenced here.

The some() method tests whether at least one element in the array passes the test implemented by the provided function.

// test cases
var str1 = 'hi, how do you do?';
var str2 = 'regular string';

// do the test strings contain these terms?
var conditions = ["hello", "hi", "howdy"];

// run the tests against every element in the array
var test1 = conditions.some(el => str1.includes(el));
var test2 = conditions.some(el => str2.includes(el));

// display results
console.log(str1, ' ===> ', test1);
console.log(str2, ' ===> ', test2);

I have just tested this and works fine.

string test = "Testing 1-2-3";

// convert string to stream
byte[] byteArray = Encoding.ASCII.GetBytes(test);
MemoryStream stream = new MemoryStream(byteArray);

// convert stream to string
StreamReader reader = new StreamReader(stream);
string text = reader.ReadToEnd();

If stream has already been written to, you might want to seek to the beginning before first before reading out the text: stream.Seek(0, SeekOrigin.Begin);

If you're developing under SharePoint 2010 or higher you can use

using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
...
string strISODate = SPUtility.CreateISO8601DateTimeFromSystemDateTime(DateTime.Now)

In this function, n can be positive or negative.

def addmonth(d, n):
    n += 1
    dd = datetime.date(d.year + n/12, d.month + n%12, 1)-datetime.timedelta(1)
    return datetime.date(dd.year, dd.month, min(d.day, dd.day))

Try this.You have some symbols in $imageUrl

<img id="id1" src="$imageUrl" onload="javascript:showImage();">

If you are using .NET 3.5 you might try with Expression trees. It is safer than reflection:

class CustomAttribute : Attribute { }

class Program
{
    [Custom]
    public int Id { get; set; }

    static void Main()
    {
        Expression<Func<Program, int>> expression = p => p.Id;
        var memberExpression = (MemberExpression)expression.Body;
        bool hasCustomAttribute = memberExpression
            .Member
            .GetCustomAttributes(typeof(CustomAttribute), false).Length > 0;
    }
}

You create the same maps.

But you can fill the difference when you will use it. With first case you'll be able to use special HashMap methods (but I don't remember anyone realy useful), and you'll be able to pass it as a HashMap parameter:

public void foo (HashMap<String, Object) { ... }

...

HashMap<String, Object> m1 = ...;
Map<String, Object> m2 = ...;

foo (m1);
foo ((HashMap<String, Object>)m2); 

There is no such particular way in which you can initialize the array after declaring it once.

There are three options only:

1.) initialize them in different lines :

int array[SIZE];

array[0] = 1;
array[1] = 2;
array[2] = 3;
array[3] = 4;
//...
//...
//...

But thats not what you want i guess.

2.) Initialize them using a for or while loop:

for (i = 0; i < MAX ; i++)  {
    array[i] = i;
}

This is the BEST WAY by the way to achieve your goal.

3.) In case your requirement is to initialize the array in one line itself, you have to define at-least an array with initialization. And then copy it to your destination array, but I think that there is no benefit of doing so, in that case you should define and initialize your array in one line itself.

And can I ask you why specifically you want to do so???

    GRV.DataSource = Class1.DataTable;
            GRV.DataBind();

Class1.GRV.Rows[e.RowIndex].Delete();
        GRV.DataSource = Class1.DataTable;
        GRV.DataBind();

start "" "c:\path with spaces\app.exe" "C:\path parameter\param.exe"

When I used above suggestion, I've got:

'c:\path' is not recognized a an internal or external command, operable program or batch file.

I think second qoutation mark prevent command to run. After some search below solution save my day:

start "" CALL "c:\path with spaces\app.exe" "C:\path parameter\param.exe"

Those two parameters (or variants of) are sent, by convention, with all events.

• sender: The object which has raised the event
• e an instance of EventArgs including, in many cases, an object which inherits from EventArgs. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.

In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs are Empty as there is no further information about the event.

Looking at the 2 parameters separately, here are some examples where they are useful.

sender

Say you have multiple buttons on a form. These buttons could contain a Tag describing what clicking them should do. You could handle all the Click events with the same handler, and depending on the sender do something different

private void HandleButtonClick(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.Tag == "Hello")
      MessageBox.Show("Hello")
    else if(btn.Tag == "Goodbye")
       Application.Exit();
    // etc.
}

Disclaimer : That's a contrived example; don't do that!

e

Some events are cancelable. They send CancelEventArgs instead of EventArgs. This object adds a simple boolean property Cancel on the event args. Code handling this event can cancel the event:

private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
    if(/* some condition*/)
    {
       // Cancel this event
       e.Cancel = true;
    }
}

You can only include a script file in an HTML page, not in another script file. That said, you can write JavaScript which loads your "included" script into the same page:

var imported = document.createElement('script');
imported.src = '/path/to/imported/script';
document.head.appendChild(imported);

There's a good chance your code depends on your "included" script, however, in which case it may fail because the browser will load the "imported" script asynchronously. Your best bet will be to simply use a third-party library like jQuery or YUI, which solves this problem for you.

// jQuery
$.getScript('/path/to/imported/script.js', function()
{
    // script is now loaded and executed.
    // put your dependent JS here.
});

svn rm --keep-local folder_name

Note: In svn 1.5.4 svn rm deletes unversioned files even when --keep-local is specified. See http://svn.haxx.se/users/archive-2009-11/0058.shtml for more information.

While the DateTime.Kind property does not have a setter, the static method DateTime.SpecifyKind creates a DateTime instance with a specified value for Kind.

Altenatively there are several DateTime constructor overloads that take a DateTimeKind parameter

You can use this command:

curl -X POST --header 'Content-Type: multipart/form-data' --header 'Accept: application/json' --header 'Authorization: <<Removed>>' -F file=@"/home/xxx/Desktop/customers.json"  'API_SERVER_URL' -k 

From the docs

IF boolean-expression THEN
    statements
ELSE
    statements
END IF;

So in your above example the code should look as follows:

IF select count(*) from orders > 0
THEN
  DELETE from orders
ELSE 
  INSERT INTO orders values (1,2,3);
END IF;

You were missing: END IF;

Perhaps the volume was created via docker-compose? If so, it should get removed by:

docker-compose down --volumes

The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, && and || only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{} construction and to direct program control rather than construct new vectors.. The & and the | operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.

When the arguments to && or || are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.

> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3

The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.

Assume a network environment where a "user" (aka you) has to logon. Usually this is a User ID (UID) and a Password (PW). OK then, what is your Identity, or who are you? You are the UID, and this gleans that "name" from your logon session. Simple! It should also work in an internet application that needs you to login, like Best Buy and others.

This will pull my UID, or "Name", from my session when I open the default page of the web application I need to use. Now, in my instance, I am part of a Domain, so I can use initial Windows authentication, and it needs to verify who I am, thus the 2nd part of the code. As for Forms Authentication, it would rely on the ticket (aka cookie most likely) sent to your workstation/computer. And the code would look like:

string id = HttpContext.Current.User.Identity.Name;

// Strip the domain off of the result
id = id.Substring(id.LastIndexOf(@"\", StringComparison.InvariantCulture) + 1);

Now it has my business name (aka UID) and can display it on the screen.

You need to set your @GeneratedId column with strategy GenerationType.IDENTITY instead of GenerationType.AUTO

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "JUD_ID")
private Long _judId;

Referencing MSDN T-SQL DELETE (Example D):

DELETE FROM Table1
FROM Tabel1 t1
   INNER JOIN Table2 t2 on t1.ID = t2.ID

Well I guess you can always use:

np.log   -->  natural log
np.log10 -->  base 10
np.log2  -->  base 2

Slightly modifying IanVS's answer:

import numpy as np
import matplotlib.pyplot as plt
from scipy.optimize import curve_fit

def func(x, a, b, c):
  #return a * np.exp(-b * x) + c
  return a * np.log(b * x) + c

x = np.linspace(1,5,50)   # changed boundary conditions to avoid division by 0
y = func(x, 2.5, 1.3, 0.5)
yn = y + 0.2*np.random.normal(size=len(x))

popt, pcov = curve_fit(func, x, yn)

plt.figure()
plt.plot(x, yn, 'ko', label="Original Noised Data")
plt.plot(x, func(x, *popt), 'r-', label="Fitted Curve")
plt.legend()
plt.show()

This results in the following graph:

A bit shorter with array_diff

$musthave = array('a','b');
$test1 = array('a','b','c');
$test2 = array('a','c');

$containsAllNeeded = 0 == count(array_diff($musthave, $test1));

// this is TRUE

$containsAllNeeded = 0 == count(array_diff($musthave, $test2));

// this is FALSE

in ubuntu or windows

• path php.ini

• php -i

• Remove the ; from ;extension=pdo_mysql or extension=php_pdo_mysql.dll and add extension=pdo_mysql.so

  restart xampp or wampp

• install sudo apt-get install php-mysql

and

php artisan migrate

When getting element by class name, don't forget the return value is an array; Hence this code:

document.getElementByClassName("dropdown-menu").scrollTop = 0

Would not work. Use code below instead.

document.getElementByClassName("dropdown-menu")[0].scrollTop = 0

I figured other people might encounter a similar problem as I did; so this should do the trick.

The PIL distribution is mispackaged for egg installation.

Install Pillow instead, the friendly PIL fork.

The type module also exists if you are checking more than ints and strings. http://docs.python.org/library/types.html

Type related errors can be avoided by imposing a schema as follows:

note: a text file was created (test.csv) with the original data (as above) and hypothetical column names were inserted ("col1","col2",...,"col25").

import pyspark
from pyspark.sql import SparkSession
import pandas as pd

spark = SparkSession.builder.appName('pandasToSparkDF').getOrCreate()

pdDF = pd.read_csv("test.csv")

contents of the pandas data frame:

       col1     col2    col3    col4    col5    col6    col7    col8   ... 
0      10000001 1       0       1       12:35   OK      10002   1      ...
1      10000001 2       0       1       12:36   OK      10002   1      ...
2      10000002 1       0       4       12:19   PA      10003   1      ...

Next, create the schema:

from pyspark.sql.types import *

mySchema = StructType([ StructField("col1", LongType(), True)\
                       ,StructField("col2", IntegerType(), True)\
                       ,StructField("col3", IntegerType(), True)\
                       ,StructField("col4", IntegerType(), True)\
                       ,StructField("col5", StringType(), True)\
                       ,StructField("col6", StringType(), True)\
                       ,StructField("col7", IntegerType(), True)\
                       ,StructField("col8", IntegerType(), True)\
                       ,StructField("col9", IntegerType(), True)\
                       ,StructField("col10", IntegerType(), True)\
                       ,StructField("col11", StringType(), True)\
                       ,StructField("col12", StringType(), True)\
                       ,StructField("col13", IntegerType(), True)\
                       ,StructField("col14", IntegerType(), True)\
                       ,StructField("col15", IntegerType(), True)\
                       ,StructField("col16", IntegerType(), True)\
                       ,StructField("col17", IntegerType(), True)\
                       ,StructField("col18", IntegerType(), True)\
                       ,StructField("col19", IntegerType(), True)\
                       ,StructField("col20", IntegerType(), True)\
                       ,StructField("col21", IntegerType(), True)\
                       ,StructField("col22", IntegerType(), True)\
                       ,StructField("col23", IntegerType(), True)\
                       ,StructField("col24", IntegerType(), True)\
                       ,StructField("col25", IntegerType(), True)])

Note: True (implies nullable allowed)

create the pyspark dataframe:

df = spark.createDataFrame(pdDF,schema=mySchema)

confirm the pandas data frame is now a pyspark data frame:

type(df)

output:

pyspark.sql.dataframe.DataFrame

Aside:

To address Kate's comment below - to impose a general (String) schema you can do the following:

df=spark.createDataFrame(pdDF.astype(str)) 

.gitignore is about ignoring other files. git is about files so this is about ignoring files. However as git works off files this file needs to be there as the mechanism to list the other file names.

If it were called .the_list_of_ignored_files it might be a little more obvious.

An analogy is a list of to-do items that you do NOT want to do. Unless you list them somewhere is some sort of 'to-do' list you won't know about them.

@Zim provided a great solution above (well deserved up-vote from me), however, it didn't quite fit what I needed since I was implementing this in Jekyll and wanted my card deck to automatically update every time I added a post to my site. Growing a card deck such as this with each new post is straight forward in Jekyll, the challenge was to correctly place the breakpoints. My solution make use of additional liquid tags and modulo mathematics.

While this question is old, I came across it and found it useful, and maybe someday someone will come along wanting to do this with Jekyll.

<div class = "container">
  <div class = "card-deck">

    {% for post in site.posts %}
      <div class = "card border-0 mt-2">
        <a href = "{{ post.url }}"><img src = "{{ site.baseurl }}{{ post.image }}" class = "mx-auto" alt = "..."></a>
        <div class = "card-body">
          <h5 class = "card-title"><a href = "{{ post.url }}">{{ post.title }}</a></h5>
          <span>Published: {{ post.date | date_to_long_string }} </span>
          <p class = "text-muted">{{ post.excerpt }}</p>
        </div>
        <div class = "card-footer bg-white border-0"><a href = "{{ post.url }}" class = "btn btn-primary">Read more</a></div>
      </div>

      <!-- Use modulo to add divs to handle break points -->
      {% assign sm = forloop.index | modulo: 2 %}
      {% assign md = forloop.index | modulo: 3 %}
      {% assign lg = forloop.index | modulo: 4 %}
      {% assign xl = forloop.index | modulo: 5 %}

      {% if sm == 0 %}
        <div class="w-100 d-none d-sm-block d-md-none"><!-- wrap every 2 on sm--></div>
      {% endif %}

      {% if md == 0 %}
        <div class="w-100 d-none d-md-block d-lg-none"><!-- wrap every 3 on md--></div>
      {% endif %}

      {% if lg == 0 %}
        <div class="w-100 d-none d-lg-block d-xl-none"><!-- wrap every 4 on lg--></div>
      {% endif %}

      {% if xl == 0 %}
        <div class="w-100 d-none d-xl-block"><!-- wrap every 5 on xl--></div>
      {% endif %}

    {% endfor %}
  </div>
</div>

This whole code block can be used directly in a website or saved in your Jekyll project _includes folder.

You can't: DataFrame columns are Series, by definition. That said, if you make the dtype (the type of all the elements) datetime-like, then you can access the quantities you want via the .dt accessor (docs):

>>> df["TimeReviewed"] = pd.to_datetime(df["TimeReviewed"])
>>> df["TimeReviewed"]
205  76032930   2015-01-24 00:05:27.513000
232  76032930   2015-01-24 00:06:46.703000
233  76032930   2015-01-24 00:06:56.707000
413  76032930   2015-01-24 00:14:24.957000
565  76032930   2015-01-24 00:23:07.220000
Name: TimeReviewed, dtype: datetime64[ns]
>>> df["TimeReviewed"].dt
<pandas.tseries.common.DatetimeProperties object at 0xb10da60c>
>>> df["TimeReviewed"].dt.year
205  76032930    2015
232  76032930    2015
233  76032930    2015
413  76032930    2015
565  76032930    2015
dtype: int64
>>> df["TimeReviewed"].dt.month
205  76032930    1
232  76032930    1
233  76032930    1
413  76032930    1
565  76032930    1
dtype: int64
>>> df["TimeReviewed"].dt.minute
205  76032930     5
232  76032930     6
233  76032930     6
413  76032930    14
565  76032930    23
dtype: int64

If you're stuck using an older version of pandas, you can always access the various elements manually (again, after converting it to a datetime-dtyped Series). It'll be slower, but sometimes that isn't an issue:

>>> df["TimeReviewed"].apply(lambda x: x.year)
205  76032930    2015
232  76032930    2015
233  76032930    2015
413  76032930    2015
565  76032930    2015
Name: TimeReviewed, dtype: int64

Its important to mention that once in 4-5 years this method might give a 1 second error, becase of a leap-second (http://www.nist.gov/pml/div688/leapseconds.cfm), and the correct formula for that day would be

(24*60*60 + 1) * 1000

There is a question Are leap seconds catered for by Calendar? and the answer is no.

So, if You're designing super time-dependant software, be careful about this formula.

ag (the silver searcher) has pretty simple syntax for this

       -G --file-search-regex PATTERN
          Only search files whose names match PATTERN.

so

ag -G *.h -G *.cpp CP_Image <path>

I'm searched many answers that suggest me to type in cmd:

set path = "%path%;c:program files\java\jdk1.7.0\bin"

but this is WRONG!

the right solution is that you leave "set" and just type

path = %path%;c:program files\java\jdk1.7.0\bin

P/s: of course you have to replace "jdk1.7.0" folder by your current java version folder. This works well on win 7 32bit, but I think it also works on win 8 - try it!

May be am late to answer this question. But still someone may get benefit out of my answer.

I had similar issue and in my case I can not change the directive since, it is a library and change a code of the library is not a good practice. So what I did was use a variable to wait for page load and use ng-if inside my html to wait render the particular element.

In my controller:

$scope.render=false;

//this will fire after load the the page

angular.element(document).ready(function() {
    $scope.render=true;
});

In my html (in my case html component is a canvas)

<canvas ng-if="render"> </canvas>

If you have named a branch incorrectly AND pushed this to the remote repository follow these steps to rename that branch (based on this article):

1. Rename your local branch:

   • If you are on the branch you want to rename:
     git branch -m new-name

   • If you are on a different branch:
     git branch -m old-name new-name

2. Delete the old-name remote branch and push the new-name local branch:
   git push origin :old-name new-name

3. Reset the upstream branch for the new-name local branch:
   Switch to the branch and then:
   git push origin -u new-name

Go to System Properties > Advanced > Enviroment Variables and look under System variables

First, create/set your JAVA_HOME variable

Even though Eclipse doesn't consult the JAVA_HOME variable, it's still a good idea to set it. See How do I run Eclipse? for more information.

If you have not created and/or do not see JAVA_HOME under the list of System variables, do the following:

1. Click New... at the very bottom
2. For Variable name, type JAVA_HOME exactly
3. For Variable value, this could be different depending on what bits your computer and java are.
   • If both your computer and java are 64-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, type C:\Program Files (x86)\Java\jdk1.8.0_60

If you have created and/or do see JAVA_HOME, do the following:

1. Click on the row under System variables that you see JAVA_HOME in
2. Click Edit... at the very bottom
3. For Variable value, change it to what was stated in #3 above based on java's and your computer's bits. To repeat:
   • If both your computer and java are 64-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, change it to C:\Program Files (x86)\Java\jdk1.8.0_60

Next, add to your PATH variable

1. Click on the row under System variables with PATH in it
2. Click Edit... at the very bottom
3. If you have a newer version of windows:
   • Click New
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60 depending on the bits of your computer and java (see above ^).
   • Press Enter and Click New again.
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre depending on the bits of your computer and java (see above again ^).
   • Press Enter and press OK on all of the related windows
4. If you have an older version of windows
   • In the Variable value textbox (or something similar) drag the cursor all the way to the very end
   • Add a semicolon (;) if there isn't one already
   • C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60
   • Add another semicolon (;)
   • C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre

Changing eclipse.ini

1. Find your eclipse.ini file and copy-paste it in the same directory (should be named eclipse(1).ini)
2. Rename eclipse.ini to eclipse.ini.old just in case something goes wrong
3. Rename eclipse(1).ini to eclipse.ini

4. Open your newly-renamed eclipse.ini and replace all of it with this:

   -startup
   plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
   --launcher.library
   plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
   -product
   org.eclipse.epp.package.java.product
   --launcher.defaultAction
   openFile
   --launcher.XXMaxPermSize
   256M
   -showsplash
   org.eclipse.platform
   --launcher.XXMaxPermSize
   256m
   --launcher.defaultAction
   openFile
   -vm
   C:\Program Files\Java\jdk1.8.0_60\bin\javaw.exe
   -vmargs
   -Dosgi.requiredJavaVersion=1.5
   -Xms40m
   -Xmx1024m
   

XXMaxPermSize may be deprecated, so it might not work. If eclipse still does not launch, do the following:

1. Delete the newer eclipse.ini
2. Rename eclipse.ini.old to eclipse.ini
3. Open command prompt
4. type in eclipse -vm C:\Program Files (x86)\Java\jdk1.8.0_60\bin\javaw.exe

If the problem remains

Try updating your eclipse and java to the latest version. 8u60 (1.8.0_60) is not the latest version of java. Sometimes, the latest version of java doesn't work with older versions of eclipse and vice versa. Otherwise, leave a comment if you're still having problems. You could also try a fresh reinstallation of Java.

Double-brace initialization is an unnecessary hack that can introduce memory leaks and other issues

There's no legitimate reason to use this "trick". Guava provides nice immutable collections that include both static factories and builders, allowing you to populate your collection where it's declared in a clean, readable, and safe syntax.

The example in the question becomes:

Set<String> flavors = ImmutableSet.of(
    "vanilla", "strawberry", "chocolate", "butter pecan");

Not only is this shorter and easier to read, but it avoids the numerous issues with the double-braced pattern described in other answers. Sure, it performs similarly to a directly-constructed HashMap, but it's dangerous and error-prone, and there are better options.

Any time you find yourself considering double-braced initialization you should re-examine your APIs or introduce new ones to properly address the issue, rather than take advantage of syntactic tricks.

Error-Prone now flags this anti-pattern.

2 out of 12 phones returned an error, found the problem was in onDrawFrame (), some objects were null, I don’t know why, I just set

if(gears==null) return;.

To convert it to a single dictionary with some decided keys value, you can use the code below.

data = ListOfDict.copy()
PrecedingText = "Obs_"
ListOfDictAsDict = {}
for i in range(len(data)):
    ListOfDictAsDict[PrecedingText + str(i)] = data[i]

I had the similar problem: EOF -warning and only part of data was loading with read.csv(). I tried the quotes="", but it only removed the EOF -warning.

But looking at the first row that was not loading, I found that there was a special character, an arrow ? (hexadecimal value 0x1A) in one of the cells. After deleting the arrow I got the data to load normally.

Just find the error reason in here and fix it.

I would like to add an answer to this that hasn't been mentioned, as I have tried all of the above to no avail. My specific situation is that I am using semantic-ui, which has built in !important attributes on elements (extremely annoying). I tried everything to override it, only in the end did one thing work (using jquery). It is as follows:

$('.active').css('cssText', 'border-radius: 0px !important');

The MySQLdb library will actually do this for you, if you use their implementations to build an SQL query string instead of trying to build your own.

Don't do:

sql = "INSERT INTO TABLE_A (COL_A,COL_B) VALUES (%s, %s)" % (val1, val2)
cursor.execute(sql)

Do:

sql = "INSERT INTO TABLE_A (COL_A,COL_B) VALUES (%s, %s)"
cursor.execute(sql, (val1, val2))

Essentially it means you don't have the index you are trying to reference. For example:

df = pd.DataFrame()
df['this']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #I haven't yet assigned how long df[data] should be!
print(df)

will give me the error you are referring to, because I haven't told Pandas how long my dataframe is. Whereas if I do the exact same code but I DO assign an index length, I don't get an error:

df = pd.DataFrame(index=[0,1,2,3,4])
df['this']=np.nan
df['is']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #since I've properly labelled my index, I don't run into this problem!
print(df)

Hope that answers your question!

How about the Dijit Calendar from the Dojo framework? It's pretty cool and very easy to implement. I always use this calendar.
https://www.dojotoolkit.org/reference-guide/dijit/Calendar.html

$ declare -a arr
$ arr=("a")
$ arr=("${arr[@]}" "new")
$ echo ${arr[@]}
a new
$ arr=("${arr[@]}" "newest")
$ echo ${arr[@]}
a new newest
