Try This one. It will generate id according to your wish.

function id()
{
 // add limit
$id_length = 20;

// add any character / digit
$alfa = "abcdefghijklmnopqrstuvwxyz1234567890";
$token = "";
for($i = 1; $i < $id_length; $i ++) {

  // generate randomly within given character/digits
  @$token .= $alfa[rand(1, strlen($alfa))];

}    
return $token;
}

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

I personally found Josh's jQuery-based answer above to be the best I saw, and worked perfectly for my application... of course, I was already using jQuery... I certainly wouldn't have included the whole jQ library just for that one purpose.

Cheers!

EDIT: OK... so mere seconds after posting this, I saw another answer just below mine (not sure if still below me after an edit) that said to use:

document.getElementById('your_element_ID_here').scrollIntoView();

This works perfectly and in so much less code than the jQuery version! I had no idea that there was a built-in function in JS called .scrollIntoView(), but there it is! So, if you want the fancy animation, go jQuery. Quick n' dirty... use this one!

>>> dict(zip(keys, values))
{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

As mentioned in other answers, request.build_absolute_uri() is perfect if you have access to request, and sites framework is great as long as different URLs point to different databases.

However, my use case was slightly different. My staging server and the production server access the same database, but get_current_site both returned the first site in the database. To resolve this, you have to use some kind of environment variable. You can either use 1) an environment variable (something like os.environ.get('SITE_URL', 'localhost:8000')) or 2) different SITE_IDs for different servers AND different settings.py.

Hopefully someone will find this useful!

This is function with inverted option

It will return:

• 'change' - string that you can use for css class in your template
• 'result' - plain result
• 'formatted' - formatted result

function getPercentageChange( $oldNumber , $newNumber , $format = true , $invert = false ){

    $value      = $newNumber - $oldNumber;

Using absolute as position is not responsive + mobile friendly. I would suggest using a div with a background-image and then placing text in the div will place text over the image. Depending on your html, you might need to use height with vh value

This one has always been a gotcha for me and many others. In short, the opening and closing tags for the <textarea> element must be on the same line, otherwise a newline character occupies it. The placeholder will therefore not be displayed since the input area contains content (a newline character is, technically, valid content).

Good:

<textarea></textarea>

Bad:

<textarea>
</textarea>

Update (2020)

This is not true anymore, according to the HTML5 parsing spec:

If the next token is a U+000A LINE FEED (LF) character token, 
then ignore that token and move on to the next one. (Newlines 
at the start of textarea elements are ignored as an authoring 
convenience.)

You might still have trouble if you editor insists on ending lines with CRLF, though.

moving element top: -12px or positioning it absolutely doesn't solve the problem but only masks it

I had the same problem - check if you have in one wrapping element mixed: floating elements with non-floating ones - my non-floating element caused this strange offset to the floating one

from the debug info, it seems that the VideoIntent from the MainActivity cannot send the path of the video to VideoActivity. It gives a NullPointerException error from the uriString. I think some of that code from VideoActivity:

Intent myIntent = getIntent();
String uri = myIntent.getStringExtra("uri");
Bundle b = myIntent.getExtras();

startVideo(b.getString(uri));

Cannot receive the uri from here:

public void playsquirrelmp4(View v) {
    Intent VideoIntent = (new Intent(this, VideoActivity.class));
    VideoIntent.putExtra("android.resource://" + getPackageName()
        + "/"+   R.raw.squirrel, uri);
    startActivity(VideoIntent);
}

Sometimes such behavior may be achieved if you try to install python3 lib in python2 folder using pip instead of pip3.

Another alternative solution, that is recommended in the github help pages:

pbcopy < ~/.ssh/id_rsa.pub

Should this fail, I recommend using their docs to trouble shoot or generate a new key - if not already done.

These are function annotations covered in PEP 3107. Specifically, the -> marks the return function annotation.

Examples:

>>> def kinetic_energy(m:'in KG', v:'in M/S')->'Joules': 
...    return 1/2*m*v**2
... 
>>> kinetic_energy.__annotations__
{'return': 'Joules', 'v': 'in M/S', 'm': 'in KG'}

Annotations are dictionaries, so you can do this:

>>> '{:,} {}'.format(kinetic_energy(20,3000),
      kinetic_energy.__annotations__['return'])
'90,000,000.0 Joules'

You can also have a python data structure rather than just a string:

>>> rd={'type':float,'units':'Joules','docstring':'Given mass and velocity returns kinetic energy in Joules'}
>>> def f()->rd:
...    pass
>>> f.__annotations__['return']['type']
<class 'float'>
>>> f.__annotations__['return']['units']
'Joules'
>>> f.__annotations__['return']['docstring']
'Given mass and velocity returns kinetic energy in Joules'

Or, you can use function attributes to validate called values:

def validate(func, locals):
    for var, test in func.__annotations__.items():
        value = locals[var]
        try: 
            pr=test.__name__+': '+test.__docstring__
        except AttributeError:
            pr=test.__name__   
        msg = '{}=={}; Test: {}'.format(var, value, pr)
        assert test(value), msg

def between(lo, hi):
    def _between(x):
            return lo <= x <= hi
    _between.__docstring__='must be between {} and {}'.format(lo,hi)       
    return _between

def f(x: between(3,10), y:lambda _y: isinstance(_y,int)):
    validate(f, locals())
    print(x,y)

Prints

>>> f(2,2) 
AssertionError: x==2; Test: _between: must be between 3 and 10
>>> f(3,2.1)
AssertionError: y==2.1; Test: <lambda>

this worked for me to solve the problem in IE8:

-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=1)";

There's a decent overview of how Facebook does it here on nfriedly.com

There's also Browser Fingerprinting, which is not the same as a cookie, but serves a like purpose in that it helps you identify a user with a fair degree of certainty. There's a post here on Stack Overflow that references upon one method of fingerprinting

You need to use .change() event as well as using # to target element by id:

$('#EventStartTimeMin').change(function() {
    if($(this).val()===""){ 
        console.log('empty');    
    }
});

Fiddle Demo

You need to use event delegation because those buttons don't exist on load:

http://jsfiddle.net/isherwood/Z7fG7/1/

 $(document).on('click', 'button.removebutton', function () { // <-- changes
     alert("aa");
     $(this).closest('tr').remove();
     return false;
 });

As explained in Spring documentation, there are several ways to do that:

Either you set the port in the command line (for example 8888)

-Dserver.port=8888 or --server.port=8888

Example : java -jar -Dserver.port=8888 test.jar

Or you set the port in the application.properties

server.port=${port:4588}

or (in application.yml with yaml syntax)

server:
   port: ${port:4588}

If the port passed by -Dport (or -Dserver.port) is set in command line then this port will be taken into account. If not, then the port will be 4588 by default.

If you want to enforce the port in properties file whatever the environment variable, you just have to write:

server.port=8888

modified_string = string.gsub(/\s+/, ' ').strip

I just fixed this problem (Different Case with same error),
The answer above I tried may not work because My case were different but produced the same error.
I think my vendor libraries were jumbled,
I get this error by:
1. Pull from remote git, master branch is codeigniter then I do composer update on master branch, I wanted to work on laravel branch then I checkout and do composer update so I get the error,

Fatal error: Class 'Illuminate\Foundation\Application' not found in C:\cms\bootstrap\app.php on line 14

Solution: I delete the project on local and do a clone again, after that I checkout to my laravel file work's branch and do composer update then it is fixed.

One of the best solutions is to add the following in your application.properties file: spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true

To change a cell value using a column name, one can use

iris$Sepal.Length[3]=999

I think you are looking for $evalAsync http://docs.angularjs.org/api/ng.$rootScope.Scope#$evalAsync

1. bind() of INADDR_ANY does NOT "generate a random IP". It binds the socket to all available interfaces.

2. For a server, you typically want to bind to all interfaces - not just "localhost".

3. If you wish to bind your socket to localhost only, the syntax would be my_sockaddress.sin_addr.s_addr = inet_addr("127.0.0.1");, then call bind(my_socket, (SOCKADDR *) &my_sockaddr, ...).

4. As it happens, INADDR_ANY is a constant that happens to equal "zero":

   http://www.castaglia.org/proftpd/doc/devel-guide/src/include/inet.h.html

   # define INADDR_ANY ((unsigned long int) 0x00000000)
   ...
   # define INADDR_NONE    0xffffffff
   ...
   # define INPORT_ANY 0
   ...
   

5. If you're not already familiar with it, I urge you to check out Beej's Guide to Sockets Programming:

   http://beej.us/guide/bgnet/

Since people are still reading this, an additional note:

man (7) ip:

When a process wants to receive new incoming packets or connections, it should bind a socket to a local interface address using bind(2).

In this case, only one IP socket may be bound to any given local (address, port) pair. When INADDR_ANY is specified in the bind call, the socket will be bound to all local interfaces.

When listen(2) is called on an unbound socket, the socket is automatically bound to a random free port with the local address set to INADDR_ANY.

When connect(2) is called on an unbound socket, the socket is automatically bound to a random free port or to a usable shared port with the local address set to INADDR_ANY...

There are several special addresses: INADDR_LOOPBACK (127.0.0.1) always refers to the local host via the loopback device; INADDR_ANY (0.0.0.0) means any address for binding...

Also:

bind() — Bind a name to a socket:

If the (sin_addr.s_addr) field is set to the constant INADDR_ANY, as defined in netinet/in.h, the caller is requesting that the socket be bound to all network interfaces on the host. Subsequently, UDP packets and TCP connections from all interfaces (which match the bound name) are routed to the application. This becomes important when a server offers a service to multiple networks. By leaving the address unspecified, the server can accept all UDP packets and TCP connection requests made for its port, regardless of the network interface on which the requests arrived.

The difference is in view-port wire-frame rendering and double-sided polygon rendering, which is very common in professional CAD/3D software but not in games.

The difference is almost 10x-13x faster in single-fixed rendering pipeline (now very obsolete but some CAD software using it) rendering double sided polygons and wireframes:

Thats how entry level Quadro beats high-end GeForce. At least in the single-fixed pipeline using legacy calls like glLightModel(GL_LIGHT_MODEL_TWO_SIDE, GL_TRUE). The trick is done with driver optimization (does not matter if its single-fixed pipeline Direct3D or OpenGL). And its true that on some GeForce cards some firmware/hardware hacking can unlock the features.

If double sided is implemented using shader code, the GeForce has to render the polygon twice giving the Quadro only 2x the speed difference (it's less in real-world). The wireframe rendering remains much much slower on GeForce even if implemented in a modern way.

Todays GeForce cards can render millions of polygons per second, drawing lines with faded polygons can result in 100x speed difference eliminating the Quadro benefit.

Quadro equivalent GTX cards have usually better clock speeds giving 2%-10% better performance in games.

So to sum up:

The Quadro rules the single-fixed legacy now obsolete rendering pipeline (which CAD uses), but by implementing modern rendering methods this can be significantly reduced (virtually no speed gain in Maya's Viewport 2.0, it uses GLSL effects - very similar to game engine).

Other reasons to get Quadro are double precision float computations for science, better warranty and display's support for professionals.

That's about it, price-vise the Quadros or FirePros are artificially overpriced.

return 0; put that wherever you want within int main() and the program will immediately close.

I used just "save in zoom", in example:

Do you mean Delegate.Invoke/BeginInvoke or Control.Invoke/BeginInvoke?

• Delegate.Invoke: Executes synchronously, on the same thread.
• Delegate.BeginInvoke: Executes asynchronously, on a threadpool thread.
• Control.Invoke: Executes on the UI thread, but calling thread waits for completion before continuing.
• Control.BeginInvoke: Executes on the UI thread, and calling thread doesn't wait for completion.

Tim's answer mentions when you might want to use BeginInvoke - although it was mostly geared towards Delegate.BeginInvoke, I suspect.

For Windows Forms apps, I would suggest that you should usually use BeginInvoke. That way you don't need to worry about deadlock, for example - but you need to understand that the UI may not have been updated by the time you next look at it! In particular, you shouldn't modify data which the UI thread might be about to use for display purposes. For example, if you have a Person with FirstName and LastName properties, and you did:

person.FirstName = "Kevin"; // person is a shared reference
person.LastName = "Spacey";
control.BeginInvoke(UpdateName);
person.FirstName = "Keyser";
person.LastName = "Soze";

Then the UI may well end up displaying "Keyser Spacey". (There's an outside chance it could display "Kevin Soze" but only through the weirdness of the memory model.)

Unless you have this sort of issue, however, Control.BeginInvoke is easier to get right, and will avoid your background thread from having to wait for no good reason. Note that the Windows Forms team has guaranteed that you can use Control.BeginInvoke in a "fire and forget" manner - i.e. without ever calling EndInvoke. This is not true of async calls in general: normally every BeginXXX should have a corresponding EndXXX call, usually in the callback.

Hope this can help you.

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

{glue} offers much better string interpolation, see my other answer. Also, as Dainis rightfully mentions, sprintf() is not without problems.

There's also sprintf():

sprintf("Current working dir: %s", wd)

To print to the console output, use cat() or message():

cat(sprintf("Current working dir: %s\n", wd))
message(sprintf("Current working dir: %s\n", wd))

Read and write text files with Python 2 and Python 3; it works with Unicode

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

# Define data
lines = ['     A first string  ',
         'A Unicode sample: €',
         'German: äöüß']

# Write text file
with open('file.txt', 'w') as fp:
    fp.write('\n'.join(lines))

# Read text file
with open('file.txt', 'r') as fp:
    read_lines = fp.readlines()
    read_lines = [line.rstrip('\n') for line in read_lines]

print(lines == read_lines)

Things to notice:

• with is a so-called context manager. It makes sure that the opened file is closed again.
• All solutions here which simply make .strip() or .rstrip() will fail to reproduce the lines as they also strip the white space.

Common file endings

.txt

More advanced file writing/reading

• CSV: Super simple format (read & write)
• JSON: Nice for writing human-readable data; VERY commonly used (read & write)
• YAML: YAML is a superset of JSON, but easier to read (read & write, comparison of JSON and YAML)
• pickle: A Python serialization format (read & write)
• MessagePack (Python package): More compact representation (read & write)
• HDF5 (Python package): Nice for matrices (read & write)
• XML: exists too *sigh* (read & write)

For your application, the following might be important:

• Support by other programming languages
• Reading/writing performance
• Compactness (file size)

In case you are rather looking for a way to make configuration files, you might want to read my short article Configuration files in Python.

Make sure this is included in your Info.plist:

<key>CFBundlePackageType</key>
<string>APPL</string>

I had APPL misspelled as AAPL. Once I fixed that and signed into Application Loader and Xcode with the same Apple ID, everything worked.

1)event.stopPropagation(): =>It is used to stop executions of its corresponding parent handler only.

2) event.stopImmediatePropagation(): => It is used to stop the execution of its corresponding parent handler and also handler or function attached to itself except the current handler. => It also stops all the handler attached to the current element of entire DOM.

Here is the example: Jsfiddle!

Thanks, -Sahil

Just to put it out there, i had the same problems. On my local homestead it would work as expected but after pushing it to the development server i got the session timeout message as well. Figuring its a environment issue i changed from apache to nginx and that miraculously made the problem go away.

If you're using Amazon Linux it's CentOS-based, which is RedHat-based. RH-based installs use yum not apt-get. Something like yum search httpd should show you the available Apache packages - you likely want yum install httpd24.

Note: Amazon Linux 2 has diverged from CentOS since the writing of this answer, but still uses yum.

In order to remove "Whitespace" which causes plenty of indentation errors when running your finished code or programs in Pyhton. Just do the following;obviously if Python keeps telling that the error(s) is indentation in line 1,2,3,4,5, etc..., just fix that line back and forth.

However, if you still get problems about the program that are related to typing mistakes, operators, etc, make sure you read why error Python is yelling at you:

The first thing to check is that you have your indentation right. If you do, then check to see if you have mixed tabs with spaces in your code.

Remember: the code will look fine (to you), but the interpreter refuses to run it. If you suspect this, a quick fix is to bring your code into an IDLE edit window, then choose Edit..."Select All from the menu system, before choosing Format..."Untabify Region. If you’ve mixed tabs with spaces, this will convert all your tabs to spaces in one go (and fix any indentation issues).

Most of the solutions above only give the full match as a result ignoring the capture groups e.g.: ^\d+\s+(\d+)

To get the capture group matches as expected you need something like (Swift4) :

public extension String {
    public func capturedGroups(withRegex pattern: String) -> [String] {
        var results = [String]()

        var regex: NSRegularExpression
        do {
            regex = try NSRegularExpression(pattern: pattern, options: [])
        } catch {
            return results
        }
        let matches = regex.matches(in: self, options: [], range: NSRange(location:0, length: self.count))

        guard let match = matches.first else { return results }

        let lastRangeIndex = match.numberOfRanges - 1
        guard lastRangeIndex >= 1 else { return results }

        for i in 1...lastRangeIndex {
            let capturedGroupIndex = match.range(at: i)
            let matchedString = (self as NSString).substring(with: capturedGroupIndex)
            results.append(matchedString)
        }

        return results
    }
}

your string is NOT a valid json to start with.

a valid json will be,

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

if you do a json_decode, it will yield,

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

Update: to use

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

Update #2:

for that true:

When TRUE, returned objects will be converted into associative arrays. for more information, click here

In my own work, I've realized that every time I've wanted something like variable-length automatic arrays or alloca(), I didn't really care that the memory was physically located on the cpu stack, just that it came from some stack allocator that didn't incur slow trips to the general heap. So I have a per-thread object that owns some memory from which it can push/pop variable sized buffers. On some platforms I allow this to grow via mmu. Other platforms have a fixed size (usually accompanied by a fixed size cpu stack as well because no mmu). One platform I work with (a handheld game console) has precious little cpu stack anyway because it resides in scarce, fast memory.

I'm not saying that pushing variable-sized buffers onto the cpu stack is never needed. Honestly I was surprised back when I discovered this wasn't standard, as it certainly seems like the concept fits into the language well enough. For me though, the requirements "variable size" and "must be physically located on the cpu stack" have never come up together. It's been about speed, so I made my own sort of "parallel stack for data buffers".

It will look better if you reserve space for the common labels by making invisible labels for the subplot in the bottom left corner. It is also good to pass in the fontsize from rcParams. This way, the common labels will change size with your rc setup, and the axes will also be adjusted to leave space for the common labels.

fig_size = [8, 6]
fig, ax = plt.subplots(5, 2, sharex=True, sharey=True, figsize=fig_size)
# Reserve space for axis labels
ax[-1, 0].set_xlabel('.', color=(0, 0, 0, 0))
ax[-1, 0].set_ylabel('.', color=(0, 0, 0, 0))
# Make common axis labels
fig.text(0.5, 0.04, 'common X', va='center', ha='center', fontsize=rcParams['axes.labelsize'])
fig.text(0.04, 0.5, 'common Y', va='center', ha='center', rotation='vertical', fontsize=rcParams['axes.labelsize'])

You can't return arrays from functions in C. You also can't (shouldn't) do this:

char *returnArray(char array []){
 char returned [10];
 //methods to pull values from array, interpret them, and then create new array
 return &(returned[0]); //is this correct?
} 

returned is created with automatic storage duration and references to it will become invalid once it leaves its declaring scope, i.e., when the function returns.

You will need to dynamically allocate the memory inside of the function or fill a preallocated buffer provided by the caller.

Option 1:

dynamically allocate the memory inside of the function (caller responsible for deallocating ret)

char *foo(int count) {
    char *ret = malloc(count);
    if(!ret)
        return NULL;

    for(int i = 0; i < count; ++i) 
        ret[i] = i;

    return ret;
}

Call it like so:

int main() {
    char *p = foo(10);
    if(p) {
        // do stuff with p
        free(p);
    }

    return 0;
}

Option 2:

fill a preallocated buffer provided by the caller (caller allocates buf and passes to the function)

void foo(char *buf, int count) {
    for(int i = 0; i < count; ++i)
        buf[i] = i;
}

And call it like so:

int main() {
    char arr[10] = {0};
    foo(arr, 10);
    // No need to deallocate because we allocated 
    // arr with automatic storage duration.
    // If we had dynamically allocated it
    // (i.e. malloc or some variant) then we 
    // would need to call free(arr)
}

I don't like "hacks" but in a quick pinch for a deadline I have done this

<li ng-if="edit === false && filtered.length === 0">
    <p ng-if="group.title != 'Dispatcher News'" style="padding: 5px">No links in group.</p>
</li>

Yes, I have another inner nested ng-if, I just didn't like too many conditions on one line.

In my case, I was getting this error because my table had

varchar(50)

but I was injecting 67 character long string, which resulted in thi error. Changing it to

varchar(255)

fixed the problem.

Identifying the column is easy:

SELECT  *
FROM    ( SELECT    id,
                    time
          FROM      dbo.a
          UNION
          SELECT    id,
                    time
          FROM      dbo.b
        )
GROUP BY id

But it doesn't solve the main problem of this query: what's to be done with the second column values upon grouping by the first? Since (peculiarly!) you're using UNION rather than UNION ALL, you won't have entirely duplicated rows between the two subtables in the union, but you may still very well have several values of time for one value of the id, and you give no hint of what you want to do - min, max, avg, sum, or what?! The SQL engine should give an error because of that (though some such as mysql just pick a random-ish value out of the several, I believe sql-server is better than that).

So, for example, change the first line to SELECT id, MAX(time) or the like!

Take a look at this. a clean and simple solution using jQuery.

http://jsfiddle.net/ma2Yd/

    <h1 onmouseover="go('The dog is in its shed')" onmouseout="clear()">lalala</h1>
    <div id="goy"></div>


    <script type="text/javascript">

    $(function() {
       $("h1").on('mouseover', function() {
          $("#goy").text('The dog is in its shed');
       }).on('mouseout', function() {
          $("#goy").text("");
       });
   });

Here's what I found that worked for being able to get the deployed folder location of my clickonce application and that hasn't been mentioned anywhere I saw in my searches, for my similar, specific scenario:

• The clickonce application is deployed to a company LAN network folder.
• The clickonce application is set to be available online or offline.
• My clickonce installation URL and Update URLs in my project properties have nothing specified. That is, there is no separate location for installation or updates.
• In my publishing options, I am having a desktop shortcut created for the clickonce application.
• The folder I want to get the path for at startup is one that I want to be accessed by the DEV, INT, and PROD versions of the application, without hardcoding the path.

Here is a visual of my use case:

• The blue boxed folders are my directory locations for each environment's application.
• The red boxed folder is the directory I want to get the path for (which requires first getting the app's deployed folder location "MyClickOnceGreatApp_1_0_0_37" which is the same as the OP).

I did not find any of the suggestions in this question or their comments to work in returning the folder that the clickonce application was deployed to (that I would then move relative to this folder to find the folder of interest). No other internet searching or related SO questions turned up an answer either.

All of the suggested properties either were failing due to the object (e.g. ActivationUri) being null, or were pointing to the local PC's cached installed app folder. Yes, I could gracefully handle null objects by a check for IsNetworkDeployed - that's not a problem - but surprisingly IsNetworkDeployed returns false even though I do in fact have a network deployed folder location for the clickonce application. This is because the application is running from the local, cached bits.

The solution is to look at:

• AppDomain.CurrentDomain.BaseDirectory when the application is being run within visual studio as I develop and
• System.Deployment.Application.ApplicationDeployment.CurrentDeployment.UpdateLocation when it is executing normally.

System.Deployment.Application.ApplicationDeployment.CurrentDeployment.UpdateLocation correctly returns the network directory that my clickonce application is deployed to, in all cases. That is, when it is launched via:

• setup.exe
• MyClickOnceGreatApp.application
• The desktop shortcut created upon first install and launch of the application.

Here's the code I use at application startup to get the path of the WorkAccounts folder. Getting the deployed application folder is simple by just not marching up to parent directories:

string directoryOfInterest = "";
if (System.Diagnostics.Debugger.IsAttached)
{
    directoryOfInterest = Directory.GetParent(Directory.GetParent(Directory.GetParent(AppDomain.CurrentDomain.BaseDirectory).FullName).FullName).FullName;
}
else
{
    try
    {
        string path = System.Deployment.Application.ApplicationDeployment.CurrentDeployment.UpdateLocation.ToString();
        path = path.Replace("file:", "");
        path = path.Replace("/", "\\");
        directoryOfInterest = Directory.GetParent(Directory.GetParent(path).FullName).FullName;
    }
    catch (Exception ex)
    {
        directoryOfInterest = "Error getting update directory needed for relative base for finding WorkAccounts directory.\n" + ex.Message + "\n\nUpdate location directory is: " + System.Deployment.Application.ApplicationDeployment.CurrentDeployment.UpdateLocation.ToString();
    }
}

I was looking for a way to sample a few members of the GroupBy obj - had to address the posted question to get this done.

create groupby object based on some_key column

grouped = df.groupby('some_key')

pick N dataframes and grab their indices

sampled_df_i  = random.sample(grouped.indices, N)

grab the groups

df_list  = map(lambda df_i: grouped.get_group(df_i), sampled_df_i)

optionally - turn it all back into a single dataframe object

sampled_df = pd.concat(df_list, axis=0, join='outer')

If you want to set only one specific class, you might write a TypeScript function returning a boolean to determine when the class should be appended.

TypeScript

function hideThumbnail():boolean{
    if (/* Your criteria here */)
        return true;
}

CSS:

.request-card-hidden {
    display: none;
}

HTML:

<ion-note [class.request-card-hidden]="hideThumbnail()"></ion-note>

My problem was that POST requests need trailing slashes '/'.

I solved it using the following:

foreach (var image in images)
{
    iTextSharp.text.Image pic = iTextSharp.text.Image.GetInstance(image, System.Drawing.Imaging.ImageFormat.Jpeg);

    if (pic.Height > pic.Width)
    {
        //Maximum height is 800 pixels.
        float percentage = 0.0f;
        percentage = 700 / pic.Height;
        pic.ScalePercent(percentage * 100);
    }
    else
    {
        //Maximum width is 600 pixels.
        float percentage = 0.0f;
        percentage = 540 / pic.Width;
        pic.ScalePercent(percentage * 100);
    }

    pic.Border = iTextSharp.text.Rectangle.BOX;
    pic.BorderColor = iTextSharp.text.BaseColor.BLACK;
    pic.BorderWidth = 3f;
    document.Add(pic);
    document.NewPage();
}

The accepted answer above:

-Duser.timezone="Europe/Sofia" 

Didn't work for me exactly. I only was able to successfully change my timezone when I didn't have quotes around the parameters:

-Duser.timezone=Europe/Sofia

mysqli_error()

As in:

$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);

Trigger error is better than die because you can use it for development AND production, it's the permanent solution.

try this:

select * from global_name;

What about this...?

#include <iostream>
#include <string>
#include <regex>

std::string ltrim( std::string str ) {
    return std::regex_replace( str, std::regex("^\\s+"), std::string("") );
}

std::string rtrim( std::string str ) {
    return std::regex_replace( str, std::regex("\\s+$"), std::string("") );
}

std::string trim( std::string str ) {
    return ltrim( rtrim( str ) );
}

int main() {

    std::string str = "   \t  this is a test string  \n   ";
    std::cout << "-" << trim( str ) << "-\n";
    return 0;

}

Note: I'm still relatively new to C++, so please forgive me if I'm off base here.

As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)

Duration column = End - Start

1. Once done, plot your stacked bar chart using the entire data.
2. Mark start and end range to no fill.
3. Right click on the X Axis and change Axis options manually. (This did cause me some issues, till I realized I couldn't manipulate them to enter dates, :) yeah I am newbie, excel masters! :))

Here's a full featured TimeOfDay class.

This is overkill for simple cases, but if you need more advanced functionality like I did, this may help.

It can handle the corner cases, some basic math, comparisons, interaction with DateTime, parsing, etc.

Below is the source code for the TimeOfDay class. You can see usage examples and learn more here:

This class uses DateTime for most of its internal calculations and comparisons so that we can leverage all of the knowledge already embedded in DateTime.

In bootstrap 4 use:

<ul class="nav navbar-nav ml-auto">

This will push the navbar to the right. Use mr-auto to push it to the left, this is the default behaviour.

Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

Since pandas 1.0.0 df.sort_values has a new parameter ignore_index which does exactly what you need:

In [1]: df2 = df.sort_values(by=['x','y'],ignore_index=True)

In [2]: df2
Out[2]:
   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0
7  2  1
8  2  2

The single " | " operator will evaluate both sides of the expression.

    if (ActionsLogWriter.Close | ErrorDumpWriter.Close == true)
{
    // Do stuff here
}

The double operator " || " will only evaluate the left side if the expression returns true.

    if (ActionsLogWriter.Close || ErrorDumpWriter.Close == true)
{
    // Do stuff here
}

C# has many similarities to C++ but their still are differences between the two languages ;)

You can keep your CONTACT parameter with the following approach:

using (var stream = new MemoryStream())
{
    var context = (HttpContextBase)Request.Properties["MS_HttpContext"];
    context.Request.InputStream.Seek(0, SeekOrigin.Begin);
    context.Request.InputStream.CopyTo(stream);
    string requestBody = Encoding.UTF8.GetString(stream.ToArray());
}

Returned for me the json representation of my parameter object, so I could use it for exception handling and logging.

Let's say for example in one case, if you want to locked cells from range A1 to I50 then below is the code:

Worksheets("Enter your sheet name").Range("A1:I50").Locked = True
ActiveSheet.Protect Password:="Enter your Password"

In another case if you already have a protected sheet then follow below code:

ActiveSheet.Unprotect Password:="Enter your Password"
Worksheets("Enter your sheet name").Range("A1:I50").Locked = True
ActiveSheet.Protect Password:="Enter your Password"

Ok I finally worked this out. This is using TortoiseHg on Windows. If you're not using that you can do it on the command line.

1. Install TortoiseHg
2. Right click an empty space in explorer, and go to the TortoiseHg settings:

3. Enable hggit:

4. Open a command line, enter an empty directory.

5. git init --bare .git (If you don't use a bare repo you'll get an error like abort: git remote error: refs/heads/master failed to update

6. cd to your Mercurial repository.

7. hg bookmarks hg

8. hg push c:/path/to/your/git/repo

9. In the Git directory: git config --bool core.bare false (Don't ask me why. Something about "work trees". Git is seriously unfriendly. I swear writing the actual code is easier than using Git.)

Hopefully it will work and then you can push from that new git repo to a non-bare one.

Try this single line solution :

import java.util.Date;
String timestamp = 
    new java.text.SimpleDateFormat("MM/dd/yyyy h:mm:ss a").format(new Date());

SIMPLE ANSWER:

   onclick="functionName(ID.value);

Where ID is the ID of the input field.

Your approach is decent for a folder that only contains files, but if you are looking for a scenario that also contains subfolders then recursion is needed

Also you should capture the return value of the return to make sure you are allowed to delete the file

and include

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

in your manifest

void DeleteRecursive(File dir)
{
    Log.d("DeleteRecursive", "DELETEPREVIOUS TOP" + dir.getPath());
    if (dir.isDirectory())
    {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++)
        {
            File temp = new File(dir, children[i]);
            if (temp.isDirectory())
            {
                Log.d("DeleteRecursive", "Recursive Call" + temp.getPath());
                DeleteRecursive(temp);
            }
            else
            {
                Log.d("DeleteRecursive", "Delete File" + temp.getPath());
                boolean b = temp.delete();
                if (b == false)
                {
                    Log.d("DeleteRecursive", "DELETE FAIL");
                }
            }
        }

    }
    dir.delete();
}

I had to get clean table without columns. I have done folowing:

jMyTable.setModel(new DefaultTableModel());

This worked for me: Add compile 'com.android.support:appcompat-v7:21.0.3' to the gradle. Change the sdk target to 21. Hope it works for you!

Using my 1.6KB library, you can do

ToString(FromUTF8(Array.from(usernameReceived)))

You will need two things. The first is @media screen to activate the specific code at a certain screen size, used for responsive design. The second is the use of the visibility: hidden attribute. Once the browser/screen reaches 600pixels then #title_message will become hidden.

@media screen and (max-width: 600px) {
  #title_message {
    visibility: hidden;
    clear: both;
    float: left;
    margin: 10px auto 5px 20px;
    width: 28%;
    display: none;
  }
}

EDIT: if you are using another CSS for mobile then just add the visibility: hidden; to #title_message. Hope this helps you!

Best way is to wrap the Image and Paragraph text with a DIV and assign a class.

Example:

<div class="image1">
    <div class="imgWrapper">
        <img src="images/img1.png" width="250" height="444" alt="Screen 1"/>
        <p>It's my first Image</p>
    </div>
    ...
    ...
    ...
    ...
</div>

{{value | number : fractionSize}}

like {{12.52311 | number : 2}}

so this will print 12.52

text-align: center will center it horizontally as for vertically put it in a span and give it a css of margin:auto 0; (you will probably also have to give the span a display: block property)

SELECT Emp_cd, Val1, Val2, Val3, SUM(Val1 + Val2 + Val3) AS TOTAL 
FROM Emp
GROUP BY Emp_cd, Val1, Val2, Val3

If you had MyPhoneExplorer installed and connected (not sure this is a must, happened to be my setup already), you could use it to control the screen with your computer mouse. It connects via ADB, for which your normal USB cable is enough.

Another solution I found that even worked without a reboot is updating tables in settings.db and locksettings.db I had to switch to root to open the settings.db though:

 adb shell
 su
 sqlite3 /data/data/com.android.providers.settings/databases/settings.db

 update secure set value=1 where name='lockscreen.disabled';
 .quit

 sqlite3 /data/system/locksettings.db

 update locksettings set value=0 where name='lock_pattern_autlock';
 update locksettings set value=1 where name='lockscreen.disabled';
 .quit

Source that made me edit my tables

Many DNS servers refuse ‘ANY’ queries. So the only way is to query for every type individually. Luckily there are sites that make this simpler. For example, https://www.nslookup.io shows the most popular record types by default, and has support for all existing record types.

I know this is a total hack but thought I should add this sample open source audio library I put on github awhile ago...

https://github.com/run-time/jThump

After clicking the link below, type on the home row keys to play a blues riff (also type multiple keys at the same time etc.)

Sample using jThump library >> http://davealger.com/apps/jthump/

It basically works by making invisible <iframe> elements that load a page that plays a sound onReady().

This is certainly not ideal but you could +1 this solution based on creativity alone (and the fact that it is open source and works in any browser that I've tried it on) I hope this gives someone else searching some ideas at least.

:)

Scan your workspace .metadata directory for files called *.launch. I forget which plugin directory exactly holds these records, but it might even be the most basic org.eclipse.plugins.core one.

In Typescript 1.5 and later, you can use for..of as opposed to for..in

var numbers = [1, 2, 3];

for (var number of numbers) {
    console.log(number);
}

It is possible of course, use -l: instead of -l. For example -l:libXYZ.a to link with libXYZ.a. Notice the lib written out, as opposed to -lXYZ which would auto expand to libXYZ.

The default is 20 minutes. http://msdn.microsoft.com/en-us/library/h6bb9cz9(v=vs.80).aspx

I've done something very similar to what 'tvanfosson' said, that is, actually using JavaScript to constantly monitor the available height in the window via events like onresize, and use that information to change the container size accordingly (as pixels rather than percentage).

Keep in mind, this does mean a JavaScript dependency, and it isn't as smooth as a CSS solution. You'd also need to ensure that the JavaScript function is capable of correctly returning the window dimensions across all major browsers.

Let us know if one of the previously mentioned CSS solutions work, as it sounds like a better way to fix the problem.

The only classes that can be static are inner classes. The following code works just fine:

public class whatever {
    static class innerclass {
    }
}

The point of static inner classes is that they don't have a reference to the outer class object.

1. embed the View you want to dismiss in a NavigationController
2. add a BarButton with "Done" as Identifier
3. invoke the Assistant Editor with the Done button selected
4. create an IBAction for this button

5. add this line into the brackets:

   self.dismissViewControllerAnimated(true, completion: nil)
   

The quick and simple answer is No.

Javascript is quite a high level language and does not have access to this sort of information.

You can use set -e as a prefix for the for-loop. Example:

all:
    set -e; for a in 1 2 3; do /bin/false; echo $$a; done

make will exit immediately with an exit code <> 0.

To answer the second part of your question, to convert to binary you can use a format string and the ord function:

>>> byte = 'a'
>>> '{0:08b}'.format(ord(byte))
'01100001'

Note that the format pads with the right number of leading zeros, which seems to be your requirement. This method needs Python 2.6 or later.

As mentioned in some of the answers/comments already, Python objects already store a dictionary of their attributes (methods aren't included). This can be accessed as __dict__, but the better way is to use vars (the output is the same, though). Note that modifying this dictionary will modify the attributes on the instance! This can be useful, but also means you should be careful with how you use this dictionary. Here's a quick example:

class A():
    def __init__(self, x=3, y=2, z=5):
        self.x = x
        self._y = y
        self.__z__ = z

    def f(self):
        pass

a = A()
print(vars(a))
# {'x': 3, '_y': 2, '__z__': 5}
# all of the attributes of `a` but no methods!

# note how the dictionary is always up-to-date
a.x = 10
print(vars(a))
# {'x': 10, '_y': 2, '__z__': 5}

# modifying the dictionary modifies the instance attribute
vars(a)["_y"] = 20
print(vars(a))
# {'x': 10, '_y': 20, '__z__': 5}

Using dir(a) is an odd, if not outright bad, approach to this problem. It's good if you really needed to iterate over all attributes and methods of the class (including the special methods like __init__). However, this doesn't seem to be what you want, and even the accepted answer goes about this poorly by applying some brittle filtering to try to remove methods and leave just the attributes; you can see how this would fail for the class A defined above.

(using __dict__ has been done in a couple of answers, but they all define unnecessary methods instead of using it directly. Only a comment suggests to use vars).

Header files can contain any valid C code, since they are injected into the compilation unit by the pre-processor prior to compilation.

If a header file contains a function, and is included by multiple .c files, each .c file will get a copy of that function and create a symbol for it. The linker will complain about the duplicate symbols.

It is technically possible to create static functions in a header file for inclusion in multiple .c files. Though this is generally not done because it breaks from the convention that code is found in .c files and declarations are found in .h files.

See the discussions in C/C++: Static function in header file, what does it mean? for more explanation.

By using environmental variables:

$BUILD_NUMBER =4

You can also create custom alert dialog by creating an xml file.

dialoglayout.xml

   <EditText
    android:id="@+id/dialog_txt_name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:hint="Name"
    android:singleLine="true" >

    <requestFocus />
  </EditText>
   <Button
        android:id="@+id/btn_login"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="60dp"
        android:background="@drawable/red"
        android:padding="5dp"
        android:textColor="#ffffff"
        android:text="Submit" />

    <Button
        android:id="@+id/btn_cancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_toRightOf="@+id/btn_login"
        android:background="@drawable/grey"
        android:padding="5dp"
        android:text="Cancel" />

The Java Code:

@Override//to popup alert dialog
public void onClick(View arg0) {
    // TODO Auto-generated method stub
    showDialog(DIALOG_LOGIN);
});


@Override
protected Dialog onCreateDialog(int id) {
    AlertDialog dialogDetails = null;

    switch (id) {
        case DIALOG_LOGIN:
            LayoutInflater inflater = LayoutInflater.from(this);
            View dialogview = inflater.inflate(R.layout.dialoglayout, null);
            AlertDialog.Builder dialogbuilder = new AlertDialog.Builder(this);
            dialogbuilder.setTitle("Title");
            dialogbuilder.setView(dialogview);
            dialogDetails = dialogbuilder.create();
            break;
    }
    return dialogDetails;
}

@Override
protected void onPrepareDialog(int id, Dialog dialog) {
    switch (id) {
        case DIALOG_LOGIN:
             final AlertDialog alertDialog = (AlertDialog) dialog;
             Button loginbutton = (Button) alertDialog
                .findViewById(R.id.btn_login);
             Button cancelbutton = (Button) alertDialog
                .findViewById(R.id.btn_cancel);
             userName = (EditText) alertDialog
                .findViewById(R.id.dialog_txt_name);
             loginbutton.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View v) {
                      String name = userName.getText().toString();
                      Toast.makeText(Activity.this, name,Toast.LENGTH_SHORT).show();
             });
             cancelbutton.setOnClickListener(new View.OnClickListener() {
                      @Override
                      public void onClick(View v) {
                           alertDialog.dismiss();
                      }
             });
             break;
   }
}

Now there is already no need to use JSON.stringify explicitly. Just execute this line of code

$.cookie.json = true;

After that you can save any object in cookie, which will be automatically converted to JSON and back from JSON when reading cookie.

var user = { name: "name", age: 25 }
$.cookie('user', user);
...

var currentUser = $.cookie('user');
alert('User name is ' + currentUser.name);

But JSON library does not come with jquery.cookie, so you have to download it by yourself and include into html page before jquery.cookie.js

You just need to return from the main function at some point. The error message says that the function is defined to return a value but you are not returning anything.

  /* .... */
  if (Date1 == Date2)  
     fprintf (stderr , "Indicating that the first date is equal to second date.\n"); 

  return 0;
}

        } else if vc.isKindOfClass(UITabBarController.self) {

            let tabBarController = vc as UITabBarController
            return UIWindow.getVisibleViewControllerFrom(tabBarController.selectedViewController!)

        } else {

            if let presentedViewController = vc.presentedViewController {

                return UIWindow.getVisibleViewControllerFrom(presentedViewController.presentedViewController!)

            } else {

                return vc;
            }
        }
    }
}

Usage:

 if let topController = window.visibleViewController() {
            println(topController)
        }

I also managed to mess up my NPM and installed packages between these Homebrew versions and no matter how many time I unlinked / linked and uninstalled / installed node it still didn't work.

As it turns out you have to remove NPM from the path otherwise Homebrew won't install it: https://github.com/mxcl/homebrew/blob/master/Library/Formula/node.rb#L117

Hope this will help someone with the same problem and save that hour or so I had to spend looking for the problem...

You need to check your SSH access as the following:

ssh -T [email protected]

this issue was because i don't add the person response on SSH in repository, read more about SSH link-1, link-2.

Use Dictionary<string, DateTime> to store token with timestamp:

static Dictionary<string, DateTime> dic = new Dictionary<string, DateTime>();

Add token with timestamp whenever you create new token:

dic.Add("yourToken", DateTime.Now);

There is a timer running to remove any expired tokens out of dic:

 timer = new Timer(1000*60); //assume run in 1 minute
 timer.Elapsed += timer_Elapsed;

 static void timer_Elapsed(object sender, ElapsedEventArgs e)
    {
        var expiredTokens = dic.Where(p => p.Value.AddDays(1) <= DateTime.Now)
                              .Select(p => p.Key);

        foreach (var key in expiredTokens)
            dic.Remove(key);
    }

So, when you authenticate token, just check whether token exists in dic or not.

Just noticed that I had named my file ' index.html' instead for 'index.html' with a leading space. That was why it could not find it.

The file extension may be case sentive...but the code works.

Set objFSO = CreateObject("Scripting.FileSystemObject")
  objStartFolder = "C:\Dev\"

  Set objFolder = objFSO.GetFolder(objStartFolder)
  Wscript.Echo objFolder.Path

  Set colFiles = objFolder.Files

  For Each objFile in colFiles
  strFileName = objFile.Name

  If objFSO.GetExtensionName(strFileName) = "pdf" Then
      Wscript.Echo objFile.Name
  End If

  Next
  Wscript.Echo

  ShowSubfolders objFSO.GetFolder(objStartFolder)

  Sub ShowSubFolders(Folder)
     For Each Subfolder in Folder.SubFolders
          Wscript.Echo Subfolder.Path
          Set objFolder = objFSO.GetFolder(Subfolder.Path)
          Set colFiles = objFolder.Files
          For Each objFile in colFiles
              Wscript.Echo objFile.Name
          Next

One thing that needs to be mentioned. You have to use the x86 version of Python 2.7. OpenCV doesn't support Python x64. I banged my head on this for a bit until I figured that out.

That said, follow the steps in Abid Rahman K's answer. And as Antimony said, you'll need to do a 'from cv2 import cv'

This seems to work for me.

def make_Ramp( ramp_colors ): 
    from colour import Color
    from matplotlib.colors import LinearSegmentedColormap

    color_ramp = LinearSegmentedColormap.from_list( 'my_list', [ Color( c1 ).rgb for c1 in ramp_colors ] )
    plt.figure( figsize = (15,3))
    plt.imshow( [list(np.arange(0, len( ramp_colors ) , 0.1)) ] , interpolation='nearest', origin='lower', cmap= color_ramp )
    plt.xticks([])
    plt.yticks([])
    return color_ramp

custom_ramp = make_Ramp( ['#754a28','#893584','#68ad45','#0080a5' ] ) 

var date = new Date();_x000D_
date.setDate(date.getDate() + 7);_x000D_
_x000D_
console.log(date);

And yes, this also works if date.getDate() + 7 is greater than the last day of the month. See MDN for more information.

I would do it in an easier way:

a_b = [e for e in a if not e in b ]

..as wich wrote, this is wrong - it works only if the items are unique in the lists. And if they are, it's better to use

a_b = list(set(a) - set(b))

    public static int FindOccuranceOf(this string str,char @char, int occurance)
    {
       var result = str.Select((x, y) => new { Letter = x, Index = y })
            .Where(letter => letter.Letter == @char).ToList();
       if (occurence > result.Count || occurance <= 0)
       {
           throw new IndexOutOfRangeException("occurance");
       }
       return result[occurance-1].Index ;
    }

Here is my method for getting dates between two dates, including / w.o. including business days. It also takes source and desired date format as parameter.

public static List<String> getAllDatesBetweenTwoDates(String stdate,String enddate,String givenformat,String resultformat,boolean onlybunessdays) throws ParseException{
        DateFormat sdf;
        DateFormat sdf1;
        List<Date> dates = new ArrayList<Date>();
        List<String> dateList = new ArrayList<String>();
          SimpleDateFormat checkformat = new SimpleDateFormat(resultformat); 
          checkformat.applyPattern("EEE");  // to get Day of week
        try{
            sdf = new SimpleDateFormat(givenformat);
            sdf1 = new SimpleDateFormat(resultformat);
            stdate=sdf1.format(sdf.parse(stdate));
            enddate=sdf1.format(sdf.parse(enddate));

            Date  startDate = (Date)sdf1.parse( stdate); 
            Date  endDate = (Date)sdf1.parse( enddate);
            long interval = 24*1000 * 60 * 60; // 1 hour in millis
            long endTime =endDate.getTime() ; // create your endtime here, possibly using Calendar or Date
            long curTime = startDate.getTime();
            while (curTime <= endTime) {
                dates.add(new Date(curTime));
                curTime += interval;
            }
            for(int i=0;i<dates.size();i++){
                Date lDate =(Date)dates.get(i);
                String ds = sdf1.format(lDate);   
                if(onlybunessdays){
                    String day= checkformat.format(lDate); 
                    if(!day.equalsIgnoreCase("Sat") && !day.equalsIgnoreCase("Sun")){
                          dateList.add(ds);
                    }
                }else{
                      dateList.add(ds);
                }

                //System.out.println(" Date is ..." + ds);

            }


        }catch(ParseException e){
            e.printStackTrace();
            throw e;
        }finally{
            sdf=null;
            sdf1=null;
        }
        return dateList;
    }

And the method call would be like :

public static void main(String aregs[]) throws Exception {
        System.out.println(getAllDatesBetweenTwoDates("2015/09/27","2015/10/05","yyyy/MM/dd","dd-MM-yyyy",false));
    }

You can find the demo code : Click Here

from row in TableA select row

Or just:

TableA

In method syntax, with other operators:

TableA.Where(row => row.IsInteresting) // no .Select(), returns the whole row.

Essentially, you already are selecting all columns, the select then transforms that to the columns you care about, so you can even do things like:

from user in Users select user.LastName+", "+user.FirstName

From the Intel's manual - Instruction Set Reference, the JE and JZ have the same opcode (74 for rel8 / 0F 84 for rel 16/32) also JNE and JNZ (75 for rel8 / 0F 85 for rel 16/32) share opcodes.

JE and JZ they both check for the ZF (or zero flag), although the manual differs slightly in the descriptions of the first JE rel8 and JZ rel8 ZF usage, but basically they are the same.

Here is an extract from the manual's pages 464, 465 and 467.

 Op Code    | mnemonic  | Description
 -----------|-----------|-----------------------------------------------  
 74 cb      | JE rel8   | Jump short if equal (ZF=1).
 74 cb      | JZ rel8   | Jump short if zero (ZF ? 1).

 0F 84 cw   | JE rel16  | Jump near if equal (ZF=1). Not supported in 64-bit mode.
 0F 84 cw   | JZ rel16  | Jump near if 0 (ZF=1). Not supported in 64-bit mode.

 0F 84 cd   | JE rel32  | Jump near if equal (ZF=1).
 0F 84 cd   | JZ rel32  | Jump near if 0 (ZF=1).

 75 cb      | JNE rel8  | Jump short if not equal (ZF=0).
 75 cb      | JNZ rel8  | Jump short if not zero (ZF=0).

 0F 85 cd   | JNE rel32 | Jump near if not equal (ZF=0).
 0F 85 cd   | JNZ rel32 | Jump near if not zero (ZF=0).

The equivalent of .live() in 1.7 looks like this:

$(document).on('click', '#child', function() ...); 

Basically, watch the document for click events and filter them for #child.

I had a similar issue on my computer. Windows Defender was blocking some part of Gradle Building. I've disabled it, worked fine after that.

Using print function without parentheses works with older versions of Python but is no longer supported on Python3, so you have to put the arguments inside parentheses. However, there are workarounds, as mentioned in the answers to this question. Since the support for Python2 has ended in Jan 1st 2020, the answer has been modified to be compatible with Python3.

You could do any of these (and there may be other ways):

(1)  print("First number is {} and second number is {}".format(first, second))
(1b) print("First number is {first} and number is {second}".format(first=first, second=second)) 

or

(2) print('First number is', first, 'second number is', second) 

(Note: A space will be automatically added afterwards when separated from a comma)

or

(3) print('First number %d and second number is %d' % (first, second))

or

(4) print('First number is ' + str(first) + ' second number is' + str(second))
  

Using format() (1/1b) is preferred where available.

Assuming your code is inside an MVC controller:

public class MyController : Microsoft.AspNetCore.Mvc.Controller

From the Controller base class, you can get the IClaimsPrincipal from the User property

System.Security.Claims.ClaimsPrincipal currentUser = this.User;

You can check the claims directly (without a round trip to the database):

bool IsAdmin = currentUser.IsInRole("Admin");
var id = _userManager.GetUserId(User); // Get user id:

Other fields can be fetched from the database's User entity:

1. Get the user manager using dependency injection

   private UserManager<ApplicationUser> _userManager;
   
   //class constructor
   public MyController(UserManager<ApplicationUser> userManager)
   {
       _userManager = userManager;
   }
   

2. And use it:

   var user = await _userManager.GetUserAsync(User);
   var email = user.Email;
   

I faced this issue when I had used Open SSL and the solution was to split the cert in 3 files and use all of them doing the call with Curl:

openssl pkcs12 -in mycert.p12 -out ca.pem -cacerts -nokeys
openssl pkcs12 -in mycert.p12 -out client.pem -clcerts -nokeys 
openssl pkcs12 -in mycert.p12 -out key.pem -nocerts

curl --insecure --key key.pem --cacert ca.pem --cert client.pem:KeyChoosenByMeWhenIrunOpenSSL https://thesite

I'd like to add another vote for the StringFormat object. You can use this simply to specify "center, center" and the text will be drawn centrally in the rectangle or points provided:

StringFormat format = new StringFormat();
format.LineAlignment = StringAlignment.Center;
format.Alignment = StringAlignment.Center;

However there is one issue with this in CF. If you use Center for both values then it turns TextWrapping off. No idea why this happens, it appears to be a bug with the CF.

MS Expression Encoder can do mp4/h.264. not sure about ogg though.

In PostgreSQL 9.6, there's a new option idle_in_transaction_session_timeout which should accomplish what you describe. You can set it using the SET command, e.g.:

SET SESSION idle_in_transaction_session_timeout = '5min';

You can see this solution. It shows how to get/set cookies, but cookies are just one of the headers in a request/response. You have to override one of the Volley's *Request classes and set the required headers in getHeaders()

Here is the linked source:

public class StringRequest extends com.android.volley.toolbox.StringRequest {

private final Map<String, String> _params;

/**
 * @param method
 * @param url
 * @param params
 *            A {@link HashMap} to post with the request. Null is allowed
 *            and indicates no parameters will be posted along with request.
 * @param listener
 * @param errorListener
 */
public StringRequest(int method, String url, Map<String, String> params, Listener<String> listener,
        ErrorListener errorListener) {
    super(method, url, listener, errorListener);

    _params = params;
}

@Override
protected Map<String, String> getParams() {
    return _params;
}

/* (non-Javadoc)
 * @see com.android.volley.toolbox.StringRequest#parseNetworkResponse(com.android.volley.NetworkResponse)
 */
@Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
    // since we don't know which of the two underlying network vehicles
    // will Volley use, we have to handle and store session cookies manually
    MyApp.get().checkSessionCookie(response.headers);

    return super.parseNetworkResponse(response);
}

/* (non-Javadoc)
 * @see com.android.volley.Request#getHeaders()
 */
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    Map<String, String> headers = super.getHeaders();

    if (headers == null
            || headers.equals(Collections.emptyMap())) {
        headers = new HashMap<String, String>();
    }

    MyApp.get().addSessionCookie(headers);

    return headers;
}

}

And MyApp class:

public class MyApp extends Application {
    private static final String SET_COOKIE_KEY = "Set-Cookie";
    private static final String COOKIE_KEY = "Cookie";
    private static final String SESSION_COOKIE = "sessionid";

    private static MyApp _instance;

    private SharedPreferences _preferences;

    public static MyApp get() {

    }

    @Override
    public void onCreate() {
        super.onCreate();
        _instance = this;
            _preferences = PreferenceManager.getDefaultSharedPreferences(this);
        _requestQueue = Volley.newRequestQueue(this);
    }

    public RequestQueue getRequestQueue() {
        return _requestQueue;
    }


    /**
     * Checks the response headers for session cookie and saves it
     * if it finds it.
     * @param headers Response Headers.
     */
    public final void checkSessionCookie(Map<String, String> headers) {
        if (headers.containsKey(SET_COOKIE_KEY)
                && headers.get(SET_COOKIE_KEY).startsWith(SESSION_COOKIE)) {
                String cookie = headers.get(SET_COOKIE_KEY);
                if (cookie.length() > 0) {
                    String[] splitCookie = cookie.split(";");
                    String[] splitSessionId = splitCookie[0].split("=");
                    cookie = splitSessionId[1];
                    Editor prefEditor = _preferences.edit();
                    prefEditor.putString(SESSION_COOKIE, cookie);
                    prefEditor.commit();
                }
            }
    }

    /**
     * Adds session cookie to headers if exists.
     * @param headers
     */
    public final void addSessionCookie(Map<String, String> headers) {
        String sessionId = _preferences.getString(SESSION_COOKIE, "");
        if (sessionId.length() > 0) {
            StringBuilder builder = new StringBuilder();
            builder.append(SESSION_COOKIE);
            builder.append("=");
            builder.append(sessionId);
            if (headers.containsKey(COOKIE_KEY)) {
                builder.append("; ");
                builder.append(headers.get(COOKIE_KEY));
            }
            headers.put(COOKIE_KEY, builder.toString());
        }
    }

}

For those who have no errors in Debug mode, but do have the specified error in Release mode (and yet the project runs fine), here is something simple to try:

1. Open the XAML file corresponding to the offending xaml.cs file.
2. Make an edit--any edit, like add a space somewhere
3. Save the file and close it

This method worked for me in VS 2015, and according to other users, also 2017 and 2019

create a class with the following CSS and add it to your tags with onclick events:

cursor:pointer;

Sometimes it takes longer to figure out the regex than to just write it out in python:

import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
    s = s.replace(char, ' ')

If you need other characters you can change it to use a white-list or extend your black-list.

Sample white-list:

whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
    if char in whitelist:
        new_s += char
    else:
        new_s += ' '

Sample white-list using a generator-expression:

whitelist = string.letters + string.digits + ' '
new_s = ''.join(c for c in s if c in whitelist)

result = []
for line in text.splitlines():
    result.append(tuple(line.split(",")))

You have to do following steps.

Go to IIS ->
Sites->
Click on Your Web site ->
In Action Click on Edit Permissions ->
Security ->
Click on ADD ->
Advanced ->
Find Now ->
Add all the users in it ->
and grant all permissions to other users ->
click on Ok.

If you do above things properly you can access your web site by using your domain.
Suggestion - Do not add host name to your site it creates problem sometime. So please host your web site using your machines ip address.

Bit late but hopefully can still be useful to someone.

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

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

2. Then set the positions as and when required.

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

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

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

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

if (($("#one").length > 0)){
   alert('yes');
}

if (($("#two").length > 0)){
   alert('yes');
}

if (($("#three").length > 0)){
   alert('yes');
}

if (($("#four")).length == 0){
   alert('no');
}

This is what you need :)

You need to create installer, which will check if user has required .NET Framework 4.0. You can use WiX to create installer. It's very powerfull and customizable. Also you can use ClickOnce to create installer - it's very simple to use. It will allow you with one click add requirement to install .NET Framework 4.0.

You can go to the location ${CATALINA_HOME}/logs/ open catalina.pid. Here we will get the pid. then terminate the process. kill -9 pid

showSoftInput was not working for me at all.

I figured I needed to set the input mode : android:windowSoftInputMode="stateVisible" (here in the Activity component in the manifest)

In SQL Server 2005 and below you can use:

WHERE Orders.OrderStatus = 'Shipped'  
AND Orders.ShipDate >= DateAdd(Day, Datediff(Day,0, GetDate() -6), 0)

I tried a few of the answers on this page, but a lot of them didn't work for me. Maybe because I'm using Vim on Windows 7 (don't mock, just have pity on me :p)?

Here's the easiest one that I found that works on Vim in Windows 7:

:v/\S/d

Here's a longer answer on the Vim Wikia: http://vim.wikia.com/wiki/Remove_unwanted_empty_lines

1. To convert and append an integer, use operator += (or member function concat):

   String stringOne = "A long integer: ";
   stringOne += 123456789;
   

2. To get the string as type char[], use toCharArray():

   char charBuf[50];
   stringOne.toCharArray(charBuf, 50)
   

In the example, there is only space for 49 characters (presuming it is terminated by null). You may want to make the size dynamic.

Overhead

The cost of bringing in String (it is not included if not used anywhere in the sketch), is approximately 1212 bytes program memory (flash) and 48 bytes RAM.

This was measured using Arduino IDE version 1.8.10 (2019-09-13) for an Arduino Leonardo sketch.

For some reason my push and pull origin was changed to HTTPS-url in stead of SSH-url (probably a copy-paste error on my end), but trying to push would give me the following error after trying to login:

Username for 'https://github.com': xxx
Password for 'https://[email protected]': 
remote: Invalid username or password.

Updating the remote origin with the SSH url, solved the problem:

git remote set-url origin [email protected]:<username>/<repo>.git

Hope this helps!

In my case first i connected my pc and mobile on the same network, you can ping your mobile from pc to test the connection.

I running my project with GGTS(Groovy/Grails Tool Suite) locally then accessing website from mobile using PC IP address and it's work very well.

PS. running from local it would give url like (http://localhost:8080/projectname) you should replace localhost with PC IP address if you are trying to access your local website from mobile

We can use replace to change the values in 'mpg' to NA that corresponds to cyl==4.

mtcars %>%
     mutate(mpg=replace(mpg, cyl==4, NA)) %>%
     as.data.frame()

I had a similar question: In the manual, it describes rename as

rename [option] expression replacement file

so you can use it in this way

rename _h _half *.png

In the code: '_h' is the expression that you are looking for. '_half' is the pattern that you want to replace with. '*.png' is the range of files that you are looking for your possible target files.

Hope this can help c:

you can update your war from the command line using java commands as mentioned here:

jar -uvf test.war yourclassesdir 

Other useful commands:

Command to unzip/explode the war file

jar -xvf test.war

Command to create the war file

jar -cvf test.war yourclassesdir 

Eg:

jar -cvf test.war *
jar -cvf test.war WEB-INF META-INF

Set up a trap (you can trap several signals with one handler):

signal (SIGQUIT, my_handler);
signal (SIGINT, my_handler);

Handle the signal however you want, but be aware of limitations and gotchas:

void my_handler (int sig)
{
  /* Your code here. */
}

Postgresql have limit.

Oracle's code:

select *
from
  tbl
where rownum <= 1000;

same in Postgresql's code:

select *
from
  tbl
limit 1000

Actually I had the same problem. Have a copy of your code before trying this.

I just did git reset HEAD~

my last commit was undone then I commited it again, problem solved!

A simple way is:

while (<FILE>) { $document .= $_ }

Another way is to change the input record separator "$/". You can do it locally in a bare block to avoid changing the global record separator.

{
    open(F, "filename");
    local $/ = undef;
    $d = <F>;
}

Here's another succint alternative using itertools.groupby which also works for unordered input:

from itertools import groupby

items = [5, 1, 1, 2, 2, 1, 1, 2, 2, 3, 4, 3, 5]

results = {value: len(list(freq)) for value, freq in groupby(sorted(items))}

results

{1: 4, 2: 4, 3: 2, 4: 1, 5: 2}

            if response.destinationURL != nil {
                showAlertMessage(titleStr: APPNAME, messageStr: "File Saved in Documents!")
                
            }
        case .failure:
            showAlertMessage(titleStr: APPNAME, messageStr: response.result.error.debugDescription)
        }
    }
}

Please add these permissions to info.plist, so you will able to check the download file in Document Directory

<key>UIFileSharingEnabled</key>

Like this:

var myString = "19 51 2.108997";
var stringParts = myString.split(" ");
var html = "<span>" + stringParts[0] + " " + stringParts[1] + "</span> <span>" + stringParts[2] + "</span";

Another possible solution I came up with was:

re.sub(r'([uU]+(.)?\s)',' you ', text)

Good news! awk field separator can be a regular expression. You just need to use -F"<separator1>|<separator2>|...":

awk -F"/|=" -vOFS='\t' '{print $3, $5, $NF}' file

Returns:

tc0001  tomcat7.1  demo.example.com
tc0001  tomcat7.2  quest.example.com
tc0001  tomcat7.5  www.example.com

Here:

• -F"/|=" sets the input field separator to either / or =. Then, it sets the output field separator to a tab.

• -vOFS='\t' is using the -v flag for setting a variable. OFS is the default variable for the Output Field Separator and it is set to the tab character. The flag is necessary because there is no built-in for the OFS like -F.

• {print $3, $5, $NF} prints the 3rd, 5th and last fields based on the input field separator.

See another example:

$ cat file
hello#how_are_you
i#am_very#well_thank#you

This file has two fields separators, # and _. If we want to print the second field regardless of the separator being one or the other, let's make both be separators!

$ awk -F"#|_" '{print $2}' file
how
am

Where the files are numbered as follows:

hello#how_are_you           i#am_very#well_thank#you
^^^^^ ^^^ ^^^ ^^^           ^ ^^ ^^^^ ^^^^ ^^^^^ ^^^
  1    2   3   4            1  2   3    4    5    6

I believe you can do this:

gem "foo", path: "/path/to/foo"

Version 1.5 is very, very old.

In the latest builds, we support 32 and 64 bit JDKs. In version 4.0, we find the JDK for you on Windows. If the software can't find it, it prompts for that path.

That path would look something like this C:\Java\jdk1.7.0_45

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

how do I programmatically add an event to the user's calendar?

Which calendar?

Is there a common API they all share?

No, no more than there is a "common API they all share" for Windows calendar apps. There are some common data formats (e.g., iCalendar) and Internet protocols (e.g., CalDAV), but no common API. Some calendar apps don't even offer an API.

If there are specific calendar applications you wish to integrate with, contact their developers and determine if they offer an API. So, for example, the Calendar application from the Android open source project, that Mayra cites, offers no documented and supported APIs. Google has even explicitly told developers to not use the techniques outlined in the tutorial Mayra cites.

Another option is for you to add events to the Internet calendar in question. For example, the best way to add events to the Calendar application from the Android open source project is to add the event to the user's Google Calendar via the appropriate GData APIs.

UPDATE

Android 4.0 (API Level 14) added a CalendarContract ContentProvider.

There's the global attribute called hidden. But I'm green to all this and maybe there was a reason it wasn't mentioned yet?

The dot itself is not an operator, .^ is.

The .^ is a pointwise¹ (i.e. element-wise) power, as .* is the pointwise product.

.^ Array power. A.^B is the matrix with elements A(i,j) to the B(i,j) power. The sizes of A and B must be the same or be compatible.

C.f.

Based on what type of RFC standard encoding you want to perform or if you need to customize your encoding you might want to create your own class.

/**
 * UrlEncoder make it easy to encode your URL
 */
class UrlEncoder{
    public const STANDARD_RFC1738 = 1;
    public const STANDARD_RFC3986 = 2;
    public const STANDARD_CUSTOM_RFC3986_ISH = 3;
    // add more here

    static function encode($string, $rfc){
        switch ($rfc) {
            case self::STANDARD_RFC1738:
                return  urlencode($string);
                break;
            case self::STANDARD_RFC3986:
                return rawurlencode($string);
                break;
            case self::STANDARD_CUSTOM_RFC3986_ISH:
                // Add your custom encoding
                $entities = ['%21', '%2A', '%27', '%28', '%29', '%3B', '%3A', '%40', '%26', '%3D', '%2B', '%24', '%2C', '%2F', '%3F', '%25', '%23', '%5B', '%5D'];
                $replacements = ['!', '*', "'", "(", ")", ";", ":", "@", "&", "=", "+", "$", ",", "/", "?", "%", "#", "[", "]"];
                return str_replace($entities, $replacements, urlencode($string));
                break;
            default:
                throw new Exception("Invalid RFC encoder - See class const for reference");
                break;
        }
    }
}

Use example:

$dataString = "https://www.google.pl/search?q=PHP is **great**!&id=123&css=#kolo&[email protected])";

$dataStringUrlEncodedRFC1738 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC1738);
$dataStringUrlEncodedRFC3986 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC3986);
$dataStringUrlEncodedCutom = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_CUSTOM_RFC3986_ISH);

Will output:

string(126) "https%3A%2F%2Fwww.google.pl%2Fsearch%3Fq%3DPHP+is+%2A%2Agreat%2A%2A%21%26id%3D123%26css%3D%23kolo%26email%3Dme%40liszka.com%29"
string(130) "https%3A%2F%2Fwww.google.pl%2Fsearch%3Fq%3DPHP%20is%20%2A%2Agreat%2A%2A%21%26id%3D123%26css%3D%23kolo%26email%3Dme%40liszka.com%29"
string(86)  "https://www.google.pl/search?q=PHP+is+**great**!&id=123&css=#kolo&[email protected])"

* Find out more about RFC standards: https://datatracker.ietf.org/doc/rfc3986/ and urlencode vs rawurlencode?

One simple way to do that is:

String url = "http://test.com/Services/rest/{id}/Identifier"

UriComponents uriComponents = UriComponentsBuilder.fromUriString(url).build();
uriComponents = uriComponents.expand(Collections.singletonMap("id", "1234"));

and then adds the query params.

SHA is a hash function and AES is an encryption standard. Given an input you can use SHA to produce an output which is very unlikely to be produced from any other input. Also, some information is lost while applying the function so even if you knew how to produce an input yielding the same output, that input wouldn't likely be the same one used in the first place. On the other hand AES is meant to protect from disclosure to third parties any data sent between two parties sharing the same encryption key. This means that once you know the encryption key and the output (and the IV...) you can seamlessly get back to the original input. Please notice that SHA doesn't require anything but an input to be applied, while AES requires at least 3 thins: what you're encrypting/decrypting, an encryption key and the initialization vector (IV).

A slightly different implementation of a half sieve using Numpy:

http://rebrained.com/?p=458

import math
import numpy
def prime6(upto):
    primes=numpy.arange(3,upto+1,2)
    isprime=numpy.ones((upto-1)/2,dtype=bool)
    for factor in primes[:int(math.sqrt(upto))]:
        if isprime[(factor-2)/2]: isprime[(factor*3-2)/2:(upto-1)/2:factor]=0
    return numpy.insert(primes[isprime],0,2)

Can someone compare this with the other timings? On my machine it seems pretty comparable to the other Numpy half-sieve.

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

try this:

<a id="send-thoughts" href="">Click</a>
<textarea id="message"></textarea>
<!--<textarea id="#message"></textarea>-->

            jQuery("a#send-thoughts").click(function() {
                //var thought = jQuery("textarea#message").val();
                var thought = $("#message").val();
                alert(thought);
            });

In my case, /storage/emulated/0/ corresponds to my device's root path. For example, when i take a photo with my phone's default camera application, the images are saved automatically /store/emulated/0/DCIM/Camera/mypicname.jpeg

For example, suppose that you want to store your pictures in /Pictures directory, namely in Pictures directory which exist in root directory. So you use the below code.

File storageDir = Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_PICTURES );

If you want to save the images in DCIM or Downloads directory, give the below arguments to the Environment.getExternalStoragePublicDirectory() method shown above.

Environment.DIRECTORY_DCIM
Environment.DIRECTORY_Downloads

Then specify your image name :

String imageFileName = "JPEG_" + timeStamp + "_";

Then create the file object as shown below. You specify the suffix as the 2nd argument.

File image = File.createTempFile(
            imageFileName,  // prefix
            ".jpg",         // suffix
            storageDir      // directory
);

Use the collapse argument to paste:

paste(a,collapse=" ")
[1] "aa bb cc"

x if y else z is the syntax for the expression you're returning for each element. Thus you need:

[ x if x%2 else x*100 for x in range(1, 10) ]

The confusion arises from the fact you're using a filter in the first example, but not in the second. In the second example you're only mapping each value to another, using a ternary-operator expression.

With a filter, you need:

[ EXP for x in seq if COND ]

Without a filter you need:

[ EXP for x in seq ]

and in your second example, the expression is a "complex" one, which happens to involve an if-else.

isNull()/isNotNull() will return the respective rows which have dt_mvmt as Null or !Null.

method_1 = df.filter(df['dt_mvmt'].isNotNull()).count()
method_2 = df.filter(df.dt_mvmt.isNotNull()).count()

Both will return the same result

Try to run below example in order to feel how the magical variables work.

@echo off

SETLOCAL EnableDelayedExpansion

echo Full path and filename: %~f0
echo Drive: %~d0
echo Path: %~p0
echo Drive and path: %~dp0
echo Filename without extension: %~n0
echo Filename with    extension: %~nx0
echo Extension: %~x0

echo date time : %~t0
echo file size: %~z0

ENDLOCAL

The related rules are following.

%~I         - expands %I removing any surrounding quotes ("")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

In my case this got the job done:

const chbx = document.getElementsByName("input_name");

for(let i=0; i < chbx.length; i++) {
    chbx[i].checked = false;
}

Take a look at http://vpython.org/contents/docs/visual/VisualIntro.html.

It provides a vector class which has a method A.rotate(theta,B). It also provides a helper function rotate(A,theta,B) if you don't want to call the method on A.

The transforms are SVG transforms (for details, have a look at the standard; here are some examples). Basically, scale and translate apply the respective transformations to the coordinate system, which should work as expected in most cases. You can apply more than one transform however (e.g. first scale and then translate) and then the result might not be what you expect.

When working with the transforms, keep in mind that they transform the coordinate system. In principle, what you say is true -- if you apply a scale > 1 to an object, it will look bigger and a translate will move it to a different position relative to the other objects.

Here is Haagenti's answer updated to Swift 4.2:

class PaddedTextField: UITextField {

    func getPadding(plusExtraFor clearButtonMode: ViewMode) -> UIEdgeInsets {
        var padding = UIEdgeInsets(top: 11, left: 16, bottom: 11, right: 16)

        // Add additional padding on the right side when showing the clear button
        if self.clearButtonMode == .always || self.clearButtonMode == clearButtonMode {
            padding.right = 28
        }

        return padding
    }

    override open func textRect(forBounds bounds: CGRect) -> CGRect {
        let padding = getPadding(plusExtraFor: .unlessEditing)
        return bounds.inset(by: padding)
    }

Because JSON has a string data type (which is practically anything between " and "). It does not have a data type that matches something

You can use PyVirtualDisplay (a Python wrapper for Xvfb) to run headless WebDriver tests.

#!/usr/bin/env python

from pyvirtualdisplay import Display
from selenium import webdriver

display = Display(visible=0, size=(800, 600))
display.start()

# now Firefox will run in a virtual display. 
# you will not see the browser.
browser = webdriver.Firefox()
browser.get('http://www.google.com')
print browser.title
browser.quit()

display.stop()

more info

You can also use xvfbwrapper, which is a similar module (but has no external dependencies):

from xvfbwrapper import Xvfb

vdisplay = Xvfb()
vdisplay.start()

# launch stuff inside virtual display here

vdisplay.stop()

or better yet, use it as a context manager:

from xvfbwrapper import Xvfb

with Xvfb() as xvfb:
    # launch stuff inside virtual display here.
    # It starts/stops in this code block.

Use this...

var all_matches = your_string.match(re);
console.log(all_matches)

It will return an array of all matches...That would work just fine.... But remember it won't take groups in account..It will just return the full matches...

Lone Ranger is very close... in fact, you also need to specify the datatype of the renamed column. For example:

ALTER TABLE `xyz` CHANGE `manufacurerid` `manufacturerid` INT;

Remember :

• Replace INT with whatever your column data type is (REQUIRED)
• Tilde/ Backtick (`) is optional

just use class='text-center' in element for center heading.

<h2 class="text-center">sample center heading</h2>

use class='text-left' in element for left heading, and use class='text-right' in element for right heading.

Not sure if this is cheating or not:

window.say = function(a) { alert(a); };

var a = "say('hello')";

var p = /^([^(]*)\('([^']*)'\).*$/;                 // ["say('hello')","say","hello"]

var fn = window[p.exec(a)[1]];                      // get function reference by name

if( typeof(fn) === "function") 
    fn.apply(null, [p.exec(a)[2]]);                 // call it with params

Given a list:

var list = new List<Child>()
{
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};

The query would look like:

var newList = list
    .GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
    .Select(y => new ConsolidatedChild()
        {
            FavoriteColor = y.Key.FavoriteColor,
            Friend = y.Key.Friend,
            School = y.Key.School,
            Children = y.ToList()
        }
    );

Test code:

foreach(var item in newList)
{
    Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
    foreach(var child in item.Children)
    {
        Console.WriteLine("\t Name: {0}", child.Name);
    }
}

Result:

School: School1 FavouriteColor: blue Friend: Bob
    Name: John
    Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
    Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
    Name: Bob

The code that is written in the question has a bug in it

Your arraylist contains strings of " 1" " 3" " 4" " 9" and " 2" (note the spaces)

So IndexOf(4) will find nothing because 4 is an int, and even "tostring" would convert it to of "4" and not " 4", and nothing will get removed.

An arraylist is the correct way to go to do what you want.

Use:

public int getDifferenceDays(Date d1, Date d2) {
    int daysdiff = 0;
    long diff = d2.getTime() - d1.getTime();
    long diffDays = diff / (24 * 60 * 60 * 1000) + 1;
    daysdiff = (int) diffDays;
    return daysdiff;
}

There is maybe a bit of a gotcha in the phrasing of the original question:

I need to check that two conditions are both true before enabling a button

The first thing to remember that the ng-disabled directive is evaluating a condition under which the button should be, well, disabled, but the original question is referring to the conditions under which it should en enabled. It will be enabled under any circumstances where the ng-disabled expression is not "truthy".

So, the first consideration is how to rephrase the logic of the question to be closer to the logical requirements of ng-disabled. The logical inverse of checking that two conditions are true in order to enable a button is that if either condition is false then the button should be disabled.

Thus, in the case of the original question, the pseudo-expression for ng-disabled is "disable the button if condition1 is false or condition2 is false". Translating into the Javascript-like code snippet required by Angular (https://docs.angularjs.org/guide/expression), we get:

!condition1 || !condition2

Zoomlar has it right!

I know this is a fairly old question, but I ran into the same problem today and wasn't too interested in referencing all of MVVMLight just so I can use event triggers with event args. I have used MVVMLight in the past and it's a great framework, but I just don't want to use it for my projects any more.

What I did to resolve this problem was create an ULTRA minimal, EXTREMELY adaptable custom trigger action that would allow me to bind to the command and provide an event args converter to pass on the args to the command's CanExecute and Execute functions. You don't want to pass the event args verbatim, as that would result in view layer types being sent to the view model layer (which should never happen in MVVM).

Here is the EventCommandExecuter class I came up with:

public class EventCommandExecuter : TriggerAction<DependencyObject>
{
    #region Constructors

    public EventCommandExecuter()
        : this(CultureInfo.CurrentCulture)
    {
    }

    public EventCommandExecuter(CultureInfo culture)
    {
        Culture = culture;
    }

    #endregion

    #region Properties

    #region Command

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    public static readonly DependencyProperty CommandProperty =
        DependencyProperty.Register("Command", typeof(ICommand), typeof(EventCommandExecuter), new PropertyMetadata(null));

    #endregion

    #region EventArgsConverterParameter

    public object EventArgsConverterParameter
    {
        get { return (object)GetValue(EventArgsConverterParameterProperty); }
        set { SetValue(EventArgsConverterParameterProperty, value); }
    }

    public static readonly DependencyProperty EventArgsConverterParameterProperty =
        DependencyProperty.Register("EventArgsConverterParameter", typeof(object), typeof(EventCommandExecuter), new PropertyMetadata(null));

    #endregion

    public IValueConverter EventArgsConverter { get; set; }

    public CultureInfo Culture { get; set; }

    #endregion

    protected override void Invoke(object parameter)
    {
        var cmd = Command;

        if (cmd != null)
        {
            var param = parameter;

            if (EventArgsConverter != null)
            {
                param = EventArgsConverter.Convert(parameter, typeof(object), EventArgsConverterParameter, CultureInfo.InvariantCulture);
            }

            if (cmd.CanExecute(param))
            {
                cmd.Execute(param);
            }
        }
    }
}

This class has two dependency properties, one to allow binding to your view model's command, the other allows you to bind the source of the event if you need it during event args conversion. You can also provide culture settings if you need to (they default to the current UI culture).

This class allows you to adapt the event args so that they may be consumed by your view model's command logic. However, if you want to just pass the event args on verbatim, simply don't specify an event args converter.

The simplest usage of this trigger action in XAML is as follows:

<i:Interaction.Triggers>
    <i:EventTrigger EventName="NameChanged">
        <cmd:EventCommandExecuter Command="{Binding Path=Update, Mode=OneTime}" EventArgsConverter="{x:Static c:NameChangedArgsToStringConverter.Default}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>

If you needed access to the source of the event, you would bind to the owner of the event

<i:Interaction.Triggers>
    <i:EventTrigger EventName="NameChanged">
        <cmd:EventCommandExecuter 
            Command="{Binding Path=Update, Mode=OneTime}" 
            EventArgsConverter="{x:Static c:NameChangedArgsToStringConverter.Default}"
            EventArgsConverterParameter="{Binding ElementName=SomeEventSource, Mode=OneTime}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>

(this assumes that the XAML node you're attaching the triggers to has been assigned x:Name="SomeEventSource"

This XAML relies on importing some required namespaces

xmlns:cmd="clr-namespace:MyProject.WPF.Commands"
xmlns:c="clr-namespace:MyProject.WPF.Converters"
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

and creating an IValueConverter (called NameChangedArgsToStringConverter in this case) to handle the actual conversion logic. For basic converters I usually create a default static readonly converter instance, which I can then reference directly in XAML as I have done above.

The benefit of this solution is that you really only need to add a single class to any project to use the interaction framework much the same way that you would use it with InvokeCommandAction. Adding a single class (of about 75 lines) should be much more preferable to an entire library to accomplish identical results.

NOTE

this is somewhat similar to the answer from @adabyron but it uses event triggers instead of behaviours. This solution also provides an event args conversion ability, not that @adabyron's solution could not do this as well. I really don't have any good reason why I prefer triggers to behaviours, just a personal choice. IMO either strategy is a reasonable choice.

Memcached is good at being a simple key/value store and is good at doing key => STRING. This makes it really good for session storage.

Redis is good at doing key => SOME_OBJECT.

It really depends on what you are going to be putting in there. My understanding is that in terms of performance they are pretty even.

Also good luck finding any objective benchmarks, if you do find some kindly send them my way.

Syntax for establishing a raw network connection using telnet is this:

telnet {domain_name} {port_number}

So telnet to your smtp server like

telnet smtp.mydomain.com 25

And copy and paste the below

helo client.mydomain.com
mail from:<[email protected]>
rcpt to:<[email protected]>
data
From: [email protected]
Subject: test mail from command line

this is test number 1
sent from linux box
.
quit

Note : Do not forgot the "." at the end which represents the end of the message. The "quit" line exits ends the session.

In windows, specified protocol for application can be registered in Registry. In this msdn doc shows Registering an Application to a URI Scheme.

For example, an executable files 'alert.exe' is to be started. The following item can be registered.

HKEY_CLASSES_ROOT
   alert
      (Default) = "URL:Alert Protocol"
      URL Protocol = ""
      DefaultIcon
         (Default) = "alert.exe,1"
      shell
         open
            command
               (Default) = "C:\Program Files\Alert\alert.exe"

Then you can write a html to test

<head>
    <title>alter</title>
</head>

<body>
    <a href="alert:" >alert</a>
<body>

The tool is called "Microsoft URL Rewrite Module 2.0 for IIS 7" and is described as follows by Microsoft: "URL Rewrite Module 2.0 provides a rule-based rewriting mechanism for changing requested URL’s before they get processed by web server and for modifying response content before it gets served to HTTP clients"

This has been an old question but solution is very simple to that. If you are ever unsure about how to write criterias, joins etc in hibernate then best way is using native queries. This doesn't slow the performance and very useful. Eq. below

    @Query(nativeQuery = true, value = "your sql query")
returnTypeOfMethod methodName(arg1, arg2);

I tried @Mr. Stark answer. It didn't work. It failed to install the drive. I have Samsung S8 plus. I enabled the debugging mode on device then installed Android USB Driver for Windows from Samsung site, it works.

I faced this issue when trying to set something to redis. The problem was that I previously used "set" method to set data with a certain key, like

$redis->set('persons', $persons)

Later I decided to change to "hSet" method, and I tried it this way

foreach($persons as $person){
    $redis->hSet('persons', $person->id, $person);
}

Then I got the aforementioned error. So, what I had to do is to go to redis-cli and manually delete "persons" entry with

del persons

It simply couldn't write different data structure under existing key, so I had to delete the entry and hSet then.

Use DateTime::createFromFormat

$date = date_create_from_format('d/m/Y:H:i:s', $s);
$date->getTimestamp();

Unlike object oriented languages such as Smalltalk or Python, where the constructor is a virtual method of the object representing the class (which means you don't need the GoF abstract factory pattern, as you can pass the object representing the class around instead of making your own), C++ is a class based language, and does not have objects representing any of the language's constructs. The class does not exist as an object at runtime, so you can't call a virtual method on it.

This fits with the 'you don't pay for what you don't use' philosophy, though every large C++ project I've seen has ended up implementing some form of abstract factory or reflection.

Check if IIS server installed the URL rewrite feature.
If it is not installed then make sure your web.config file don't have the URL rewrite related configuration

<!-- Make sure don't have below config, if server have not installed url rewrite feature. -->
<rewrite>
  <rules>
    <rule name="Fail bad requests">
      <match url=".*"/> ...

Some time we copied the config from legacy server and straight away deploy to brand new server, then we may encounter such kind of 500 issue.

If you have a folder and sub-folder full of wav's you want to convert, put below command in a file, save it in a .bat file in the root of the folder where you wan to convert, and then run the bat file

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

public static class DbEx {
    public static IEnumerable<T> SqlQueryPrm<T>(this System.Data.Entity.Database database, string sql, object parameters) {
        using (var tmp_cmd = database.Connection.CreateCommand()) {
            var dict = ToDictionary(parameters);
            int i = 0;
            var arr = new object[dict.Count];
            foreach (var one_kvp in dict) {
                var param = tmp_cmd.CreateParameter();
                param.ParameterName = one_kvp.Key;
                if (one_kvp.Value == null) {
                    param.Value = DBNull.Value;
                } else {
                    param.Value = one_kvp.Value;
                }
                arr[i] = param;
                i++;
            }
            return database.SqlQuery<T>(sql, arr);

    private static IDictionary<string, object> ToDictionary(object data) {
        var attr = System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance;
        var dict = new Dictionary<string, object>();
        foreach (var property in data.GetType().GetProperties(attr)) {
            if (property.CanRead) {
                dict.Add(property.Name, property.GetValue(data, null));
            }
        }
        return dict;
    }
}

Usage:

var names = db.Database.SqlQueryPrm<string>("select name from position_category where id_key=@id_key", new { id_key = "mgr" }).ToList();
