Just add a . to it:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

That means: check out to current directory.

Use export if you want to upload (or give to somebody) a project. If you are working with a project, use checkout.

I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:

Use git svn clone to clone the last 50 revisions

# -u    The SVN URL to clone
# -l    The limit of revisions
# -o    The output directory

./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt

Find the previous N revision from an SVN repo

# -u    The SVN URL to clone
# -l    The limit of revisions

./svn-lookback.sh -u https://server/project/trunk -l 5     

You can track by $index if your data source has duplicate identifiers

e.g.: $scope.dataSource: [{id:1,name:'one'}, {id:1,name:'one too'}, {id:2,name:'two'}]

You can't iterate this collection while using 'id' as identifier (duplicate id:1).

WON'T WORK:

<element ng-repeat="item.id as item.name for item in dataSource">
  // something with item ...
</element>

but you can, if using track by $index:

<element ng-repeat="item in dataSource track by $index">
  // something with item ...
</element>

I too had the same problem.

The solution for me was to add following in the pom.xml as suggested here.

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.0.2</version>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
</build>

This is an example of how to POST multi-part data WITHOUT using external Apache libraries:

byte[] buffer = getBuffer();

if(buffer.length > 0) {
   String lineEnd = "\r\n"; 
   String twoHyphens = "--"; 
   String boundary =  "RQdzAAihJq7Xp1kjraqf"; 

   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   DataOutputStream dos = new DataOutputStream(baos);

   // Send parameter #1
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param1\"" + lineEnd);
   dos.writeBytes("Content-Type: text/plain; charset=US-ASCII" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: 8bit" + lineEnd);
   dos.writeBytes(lineEnd);
   dos.writeBytes(myStringData + lineEnd);

   // Send parameter #2
   //dos.writeBytes(twoHyphens + boundary + lineEnd); 
   //dos.writeBytes("Content-Disposition: form-data; name=\"param2\"" + lineEnd + lineEnd);
   //dos.writeBytes("foo2" + lineEnd);

   // Send a binary file
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param3\";filename=\"test_file.dat\"" + lineEnd); 
   dos.writeBytes("Content-Type: application/octet-stream" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: binary" + lineEnd);
   dos.writeBytes(lineEnd); 
   dos.write(buffer);
   dos.writeBytes(lineEnd); 
   dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
   dos.flush(); 
   dos.close();

   ByteArrayInputStream content = new ByteArrayInputStream(baos.toByteArray());
   BasicHttpEntity entity = new BasicHttpEntity();
   entity.setContent(content);

   HttpPost httpPost = new HttpPost(myURL);
   httpPost.addHeader("Connection", "Keep-Alive");
   httpPost.addHeader("Content-Type", "multipart/form-data; boundary="+boundary);

   //MultipartEntity entity = new MultipartEntity();
   //entity.addPart("param3", new ByteArrayBody(buffer, "test_file.dat"));
   //entity.addPart("param1", new StringBody(myStringData));

   httpPost.setEntity(entity);

   /*
   String httpData = "";
   ByteArrayOutputStream baos1 = new ByteArrayOutputStream();
   entity.writeTo(baos1);
   httpData = baos1.toString("UTF-8");
   */

   /*
   Header[] hdrs = httpPost.getAllHeaders();
   for(Header hdr: hdrs) {
     httpData += hdr.getName() + " | " + hdr.getValue() + " |_| ";
   }
   */

   //Log.e(TAG, "httpPost data: " + httpData);
   response = httpClient.execute(httpPost);
}

Use display: inline-block;

Explanation:

The label is an inline element, meaning it is only as big as it needs to be.

Set the display property to either inline-block or block in order for the width property to take effect.

Example:

#report-upload-form {_x000D_
    background-color: #316091;_x000D_
    color: #ddeff1;_x000D_
    font-weight: bold;_x000D_
    margin: 23px auto 0 auto;_x000D_
    border-radius: 10px;_x000D_
    width: 650px;_x000D_
    box-shadow: 0 0 2px 2px #d9d9d9;_x000D_
_x000D_
}_x000D_
_x000D_
#report-upload-form label {_x000D_
    padding-left: 26px;_x000D_
    width: 125px;_x000D_
    text-transform: uppercase;_x000D_
    display: inline-block;_x000D_
}_x000D_
_x000D_
#report-upload-form input[type=text], _x000D_
#report-upload-form input[type=file],_x000D_
#report-upload-form textarea {_x000D_
    width: 305px;_x000D_
}

<form id="report-upload-form" method="POST" action="" enctype="multipart/form-data">_x000D_
    <p><label for="id_title">Title:</label> <input id="id_title" type="text" class="input-text" name="title"></p>_x000D_
    <p><label for="id_description">Description:</label> <textarea id="id_description" rows="10" cols="40" name="description"></textarea></p>_x000D_
    <p><label for="id_report">Upload Report:</label> <input id="id_report" type="file" class="input-file" name="report"></p>_x000D_
</form>

As an option, you can use a type casting. If you have this error from typescript that means that some variable has type or is undefined:

let a: string[] | undefined;

let b: number = a.length; // [ts] Object is possibly 'undefined'
let c: number = (a as string[]).length; // ok

Be sure that a really exist in your code.

This should answer that question, and then some.

The second line, if (obj.GetType() == typeof(ClassA)) {}, is faster, for those that don't want to read the article.

(Be aware that they don't do the same thing)

An alternative way you can do this, is using dictionary comprehension. This should be compatible with 2.7+

result = {
    key: value for key, value in
    {"foo": "bar", "lorem": None}.items()
    if value
}

https://docs.python.org/library/os.html

To complement Greg's post, if you're on a posix system, which includes MacOS, Linux, Unix, etc. you can use os.uname() to get a better feel for what kind of system it is.

This might be extremely convoluted and I might be missing the obvious, but without OpenPyXL filling in the column_dimensions in Iterable Worksheets (see my comment above), the only way I can see of finding the column size without loading everything is to parse the xml directly:

from xml.etree.ElementTree import iterparse
from openpyxl import load_workbook
wb=load_workbook("/path/to/workbook.xlsx", use_iterators=True)
ws=wb.worksheets[0]
xml = ws._xml_source
xml.seek(0)

for _,x in iterparse(xml):

    name= x.tag.split("}")[-1]
    if name=="col":
        print "Column %(max)s: Width: %(width)s"%x.attrib # width = x.attrib["width"]

    if name=="cols":
        print "break before reading the rest of the file"
        break

I am using:

    ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
    //configMap.ExeConfigFilename = @"d:\test\justAConfigFile.config.whateverYouLikeExtension";
    configMap.ExeConfigFilename = AppDomain.CurrentDomain.BaseDirectory + ServiceConstants.FILE_SETTING;
    Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);
    value1 = System.Configuration.ConfigurationManager.AppSettings["NewKey0"];
    value2 = config.AppSettings.Settings["NewKey0"].Value;
    value3 = ConfigurationManager.AppSettings["NewKey0"];

Where value1 = ... and value3 = ... gives null and value2 = ... works

Then I decided to replace the internal app.config with:

// Note works in service but not in wpf
AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", @"d:\test\justAConfigFile.config.whateverYouLikeExtension");
ConfigurationManager.RefreshSection("appSettings");

string value = ConfigurationManager.AppSettings["NewKey0"];

Using VS2012 .net 4

If using the following HTML:

<button id="submit-button"></button>

Style can be applied through JS using the style object available on an HTMLElement.

To set height and width to 200px of the above example button, this would be the JS:

var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';

I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.

Using async/await

async changeHandler(event) {
    await this.setState({ yourName: event.target.value });
    console.log(this.state.yourName);
}

Basicaly a promisified version of @espascarello and @adeneo answers, with a fallback parameter:

const getImageOrFallback = (path, fallback) => {_x000D_
  return new Promise(resolve => {_x000D_
    const img = new Image();_x000D_
    img.src = path;_x000D_
    img.onload = () => resolve(path);_x000D_
    img.onerror = () => resolve(fallback);_x000D_
  });_x000D_
};_x000D_
_x000D_
// Usage:_x000D_
_x000D_
const link = getImageOrFallback(_x000D_
  'https://www.fillmurray.com/640/360',_x000D_
  'https://via.placeholder.com/150'_x000D_
  ).then(result => console.log(result) || result)_x000D_
_x000D_
// It can be also implemented using the async / await API.

Note: I may personally like the fetch solution more, but it has a drawback – if your server is configured in a specific way, it can return 200 / 304, even if your file doesn't exist. This, on the other hand, will do the job.

In addition to the API key that is assigned to you, Google also verifies the source of the incoming request by looking at either the REFERRER or the IP address. To run an example in curl, create a new Server Key in Google APIs console. While creating it, you must provide the IP address of the server. In this case, it will be your local IP address. Once you have created a Server Key and whitelisted your IP address, you should be able to use the new API key in curl.

My guess is you probably created your API key as a Browser Key which does not require you to whitelist your IP address, but instead uses the REFERRER HTTP header tag for validation. curl doesn't send this tag by default, so Google was failing to validate your request.

Update C# 7

Yes: Source

switch(shape)
{
    case Circle c:
        WriteLine($"circle with radius {c.Radius}");
        break;
    case Rectangle s when (s.Length == s.Height):
        WriteLine($"{s.Length} x {s.Height} square");
        break;
    case Rectangle r:
        WriteLine($"{r.Length} x {r.Height} rectangle");
        break;
    default:
        WriteLine("<unknown shape>");
        break;
    case null:
        throw new ArgumentNullException(nameof(shape));
}

Prior to C# 7

No.

http://blogs.msdn.com/b/peterhal/archive/2005/07/05/435760.aspx

We get a lot of requests for addditions to the C# language and today I'm going to talk about one of the more common ones - switch on type. Switch on type looks like a pretty useful and straightforward feature: Add a switch-like construct which switches on the type of the expression, rather than the value. This might look something like this:

switch typeof(e) { 
        case int:    ... break; 
        case string: ... break; 
        case double: ... break; 
        default:     ... break; 
}

This kind of statement would be extremely useful for adding virtual method like dispatch over a disjoint type hierarchy, or over a type hierarchy containing types that you don't own. Seeing an example like this, you could easily conclude that the feature would be straightforward and useful. It might even get you thinking "Why don't those #*&%$ lazy C# language designers just make my life easier and add this simple, timesaving language feature?"

Unfortunately, like many 'simple' language features, type switch is not as simple as it first appears. The troubles start when you look at a more significant, and no less important, example like this:

class C {}
interface I {}
class D : C, I {}

switch typeof(e) {
case C: … break;
case I: … break;
default: … break;
}

Link: https://blogs.msdn.microsoft.com/peterhal/2005/07/05/many-questions-switch-on-type/

eg:

from: /xxx/a/b/c/d/e/1.html

to: user@remote:/pre_existing/dir/b/c/d/e/1.html

rsync:

cd /xxx/a/ && rsync -auvR b/c/d/e/ user@remote:/pre_existing/dir/

Sadly, no.

I agree that such frequent operation should have easier implementation than copying of input line by line in loop, but you'll have to either write helper method or use external library.

It's also important to put

table-layout:fixed;

Onto the containing table, so it operates well in IE9 (if your utilize max-width) as well.

SELECT STR_TO_DATE(dateString, '%d/%m/%y') FROM yourTable...

php.ini probably needs to read: extension=ext\php_sqlsrv_53_nts.dll

Or move the file to same directory as the php executable. This is what I did to my php5 install this week to get odbc_pdo working. :P

Additionally, that doesn't look like proper phpinfo() output. If you make a file with contents
<? phpinfo(); ?> and visit that page, the HTML output should show several sections, including one with loaded modules. (Edited to add: like shown in the screenshot of the above accepted answer)

I have modified your code a little. Here's a working version (for me):

    <select name="dd1" id="dd1">
       <option value="none">None</option>
       <option value="o1">option 1</option>
       <option value="o2">option 2</option>
       <option value="o3">option 3</option>
    </select>  
    <div style="color:red;" id="msg_id"></div>

<script>
    $('#everything').submit(function(e){ 
        var department = $("#msg_id");
        var msg = "Please select Department";
            if ($('#dd1').val() == "") {
                department.append(msg);
                e.preventDefault();
                return false;
            }
        });
 </script>

Use proper escaping: string.split("\\|")

Or, in Java 5+, use the helper Pattern.quote() which has been created for exactly this purpose:

string.split(Pattern.quote("|"))

which works with arbitrary input strings. Very useful when you need to quote / escape user input.

Hope this helps. I was able to open pdf files from all subfolders of a folder and copy content to the macro enabled workbook using shell as recommended above.Please see below the code .

Taken from the Quake III source, I stumbled across this in some random slashdot posting. Full source of the file can be found here. It's a particularly fast method of calculating an inverse square root. As for the best comment? It's a common one to be sure, but given that it's attached to the line that does the magic is what makes it great.

float Q_rsqrt( float number )
{
  long i;
  float x2, y;
  const float threehalfs = 1.5F;

  x2 = number * 0.5F;
  y  = number;
  i  = * ( long * ) &y;  // evil floating point bit level hacking
  i  = 0x5f3759df - ( i >> 1 ); // what the fuck?
  y  = * ( float * ) &i;
  y  = y * ( threehalfs - ( x2 * y * y ) ); // 1st iteration
  // y  = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed

  #ifndef Q3_VM
  #ifdef __linux__
    assert( !isnan(y) ); // bk010122 - FPE?
  #endif
  #endif
  return y;
}

For me, other answers didn't work. I had to go to open Files and do Invalidate caches and restart on Intellij. After that, everything worked fine again.

Not too proud of this, but I didn't want to pass in environment variables so I inverted the way to run a canned command:

run:
    @echo command-you-want

this will print the command you want to run, so just evaluate it in a subshell:

$(make run) args to my command

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

I was curious about the performance of different approaches and here it is:

Tested on Python 3.5.1

batch_size = 7
arr_len = 298937

    arr = arr[batch_size:-1]
print(time.time() - start)

    tmp = arr[batch_size * i : batch_size * (i + 1)]
print(time.time() - start)

#----------batches 1------------

def batch(iterable, n=1):
    l = len(iterable)
    for ndx in range(0, l, n):

If after changing the namespace and the config/auth.php it still fails, you could try the following:

1. In the file vendor/composer/autoload_classmap.php change the line App\\User' => $baseDir . '/app/User.php',, to App\\Models\\User' => $baseDir . '/app/Models/User.php',

2. At the beginning of the file app/Services/Registrar.php change "use App\User" to "App\Models\User"

Assuming that both data1() and data2() are in the same class, then another alternative is to make data1() static.

private static void data1()
{
}
private static void data2()
{
   data1();
}

You can use scalar multiplication to modify each element in your vector.

> r <- 0:10 
> r <- r * 2
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

or

> r <- 0:10 * 2 
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

A simple and lightweight template as well:

input[type=checkbox] {_x000D_
  cursor: pointer;_x000D_
}_x000D_
_x000D_

To prevent that people are mislead by some of the comments to the other answers:

1. If .schema or query from sqlite_master not gives any output, it indicates a non-existent tablename, e.g. this may also be caused by a ; semicolon at the end for .schema, .tables, ... Or just because the table really not exists. That .schema just doesn't work is very unlikely and then a bug report should be filed at the sqlite project.

... .schema can only be used from a command line; the above commands > can be run as a query through a library (Python, C#, etc.). – Mark Rushakoff Jul 25 '10 at 21:09

2. 'can only be used from a command line' may mislead people. Almost any (likely every?) programming language can call other programs/commands. Therefore the quoted comment is unlucky as calling another program, in this case sqlite, is more likely to be supported than that the language provides a wrapper/library for every program (which not only is prone to incompleteness by the very nature of the masses of programs out there, but also is counter acting single-source principle, complicating maintenance, furthering the chaos of data in the world).

In addition to @dhaval-jivani answer.

I've updated the project github project to latest version of constraint layout v.1.1.0-beta3

I've measured and compared the time of onCreate method and time between a start of onCreate and end of execution of last preformDraw method which visible in CPU monitor. All test were done on Samsung S5 mini with android 6.0.1 Here results:

Fresh start (first screen opening after application launch)

Relative Layout

OnCreate: 123ms

Last preformDraw time - OnCreate time: 311.3ms

Constraint Layout

OnCreate: 120.3ms

Last preformDraw time - OnCreate time: 310ms

Besides that, I've checked performance test from this article , here the code and found that on loop counts less than 100 constraint layout variant is faster during execution of inflating, measure, and layout then variants with Relative Layout. And on old Android devices, like Samsung S3 with Android 4.3, the difference is bigger.

As a conclusion I agree with comments from the article:

Does it worth to refactor old views switch on it from RelativeLayout or LinearLayout?

As always: It depends

I wouldn’t refactor anything unless you either have a performance problem with your current layout hierarchy or you want to make significant changes to the layout anyway. Though I haven’t measured it lately, I haven’t found any performance issues in the last releases. So I think you should be safe to use it. but – as I’v said – don’t just migrate for the sake of migrating. Only do so, if there’s a need for and benefit from it. For new layouts, though, I nearly always use ConstraintLayout. It’s so much better compare to what we had before.

I will answer this with a general answer. Usually these answers not working with guids. Here is a working version with guids too.

var stringVal="6e3ba183-89d9-e611-80c2-00155dcfb231"; // guid value as string to set
var prop = obj.GetType().GetProperty("FooGuidProperty"); // property to be setted
var propType = prop.PropertyType;

// var will be type of guid here
var valWithRealType = TypeDescriptor.GetConverter(propType).ConvertFrom(stringVal); 

Because there are protocol overheads, and because there are other users of the network.

For those new to Maven (like me) here is the whole config that goes in the build section of your pom. Cheers.

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>

I don't think you want the data from your Request, I think you want the data from your Response. The two are different. Also you should build your response correctly in your controller.

Looking at the class in edit #2, I would make it look like this:

class XmlController extends Controller
{
    public function index()
    {
        $content = Request::all();
        return Response::json($content);
    }
}

Once you've gotten that far you should check the content of your response in your test case (use print_r if necessary), you should see the data inside.

More information on Laravel responses here:

http://laravel.com/docs/5.0/responses

As already said, the easiest way is to use querystring.

But if you cannot, because of security reason, you should consider using cookies.

Because C++ inherited them from C. Unfortunately.

JS only - no need for jquery

Simply create an input element and trigger the click.

var input = document.createElement('input');
input.type = 'file';
input.click();

This is the most basic, pop a select-a-file dialog, but its no use for anything without handling the selected file...

Handling the files

Adding an onchange event to the newly created input would allow us to do stuff once the user has selected the file.

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 
   var file = e.target.files[0]; 
}

input.click();

At the moment we have the file variable storing various information :

file.name // the file's name including extension
file.size // the size in bytes
file.type // file type ex. 'application/pdf'

Great!

But, what if we need the content of the file?

In order to get to the actual content of the file, for various reasons. place an image, load into canvas, create a window with Base64 data url, etc. we would need to use the FileReader API

We would create an instance of the FileReader, and load our user selected file reference to it.

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 

   // getting a hold of the file reference
   var file = e.target.files[0]; 

   // setting up the reader
   var reader = new FileReader();
   reader.readAsText(file,'UTF-8');

   // here we tell the reader what to do when it's done reading...
   reader.onload = readerEvent => {
      var content = readerEvent.target.result; // this is the content!
      console.log( content );
   }

}

input.click();

Trying pasting the above code into your devtool's console window, it should produce a select-a-file dialog, after selecting the file, the console should now print the contents of the file.

Example - "Stackoverflow's new background image!"

Let's try to create a file select dialog to change stackoverflows background image to something more spicy...

var input = document.createElement('input');
input.type = 'file';

input.onchange = e => { 

   // getting a hold of the file reference
   var file = e.target.files[0]; 

   // setting up the reader
   var reader = new FileReader();
   reader.readAsDataURL(file); // this is reading as data url

   // here we tell the reader what to do when it's done reading...
   reader.onload = readerEvent => {
      var content = readerEvent.target.result; // this is the content!
      document.querySelector('#content').style.backgroundImage = 'url('+ content +')';
   }

}

input.click();

open devtools, and paste the above code into console window, this should pop a select-a-file dialog, upon selecting an image, stackoverflows content box background should change to the image selected.

Cheers!

You need to add 2 methods, note __hash__ and __eq__:

class MyThing:
    def __init__(self,name,location,length):
        self.name = name
        self.location = location
        self.length = length

    def __hash__(self):
        return hash((self.name, self.location))

    def __eq__(self, other):
        return (self.name, self.location) == (other.name, other.location)

    def __ne__(self, other):
        # Not strictly necessary, but to avoid having both x==y and x!=y
        # True at the same time
        return not(self == other)

The Python dict documentation defines these requirements on key objects, i.e. they must be hashable.

Pointer helps to create user defined scope to a variable, which is called Dynamic variable. Dynamic Variable can be single variable or group of variable of same type (array) or group of variable of different types (struct). Default local variable scope starts when control enters into a function and ends when control comes out of that function. Default global vairable scope starts at program execution and ends once program finishes.

But scope of a dynamic variable which holds by a pointer can start and end at any point in a program execution, which has to be decided by a programmer. Dangling and memory leak comes into picture only if a programmer doesnt handle the end of scope.

Memory leak will occur if a programmer, doesnt write the code (free of pointer) for end of scope for dynamic variables. Any way once program exits complete process memory will be freed, at that time this leaked memory also will get freed. But it will cause a very serious problem for a process which is running long time.

Once scope of dynamic variable comes to end(freed), NULL should be assigned to pointer variable. Otherwise if the code wrongly accesses it undefined behaviour will happen. So dangling pointer is nothing but a pointer which is pointing a dynamic variable whose scope is already finished.

OP's question: "How do I convert a string to a byte array in .NET (C#)?" [sic]

You can use the following code:

static byte[] ConvertString (string s) {
    return new byte[0];
}

As a benefit, encoding does not matter! Oh wait, this is an ecoding... it's just trivial and highly lossy.

Are you running this on Windows or Linux? If you're on Windows,then you should be use a path like C:\\Users\\apple\\Downloads\train.csv . If you're on Linux, then you can follow the same path.

Here is email code I used in one of my databases. I just made variables for the person I wanted to send it to, CC, subject, and the body. Then you just use the DoCmd.SendObject command. I also set it to "True" after the body so you can edit the message before it automatically sends.

Public Function SendEmail2()

Dim varName As Variant          
Dim varCC As Variant            
Dim varSubject As Variant      
Dim varBody As Variant          

varName = "[email protected]"
varCC = "[email protected], [email protected]"
'separate each email by a ','

varSubject = "Hello"
'Email subject

varBody = "Let's get ice cream this week"

'Body of the email
DoCmd.SendObject , , , varName, varCC, , varSubject, varBody, True, False
'Send email command. The True after "varBody" allows user to edit email before sending.
'The False at the end will not send it as a Template File

End Function

Your constructor is expecting one parameter (data). You're not passing it in the call. I guess you wanted to initialise a field in the object. That would look like this:

class DHT:
    def __init__(self):
        self.data = {}
        self.data['one'] = '1'
        self.data['two'] = '2'
        self.data['three'] = '3'
    def showData(self):
        print(self.data)

if __name__ == '__main__':
    DHT().showData()

Or even just:

class DHT:
    def __init__(self):
        self.data = {'one': '1', 'two': '2', 'three': '3'}
    def showData(self):
        print(self.data)

I have just started checking out Angular(so im quite sure there are other ways to get it done which are more optimum), and i came across this question while searching for examples of ng-repeat.

The requirement by the poser(with the update):

"...but my real requirement is display the items as shown below.."

looked real-world enough (and simple), so i thought ill give it a spin and attempt to get the exact desired structure.

angular.module('appTest', [])_x000D_
  .controller("repeatCtrl", function($scope) {_x000D_
    $scope.items = [{_x000D_
      Name: "Soap",_x000D_
      Price: "25",_x000D_
      Quantity: "10"_x000D_
    }, {_x000D_
      Name: "Bag",_x000D_
      Price: "100",_x000D_
      Quantity: "15"_x000D_
    }, {_x000D_
      Name: "Pen",_x000D_
      Price: "15",_x000D_
      Quantity: "13"_x000D_
    }];_x000D_
  })

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<body ng-app="appTest">_x000D_
  <section ng-controller="repeatCtrl">_x000D_
    <table>_x000D_
      <thead>_x000D_
        <tr ng-repeat="item in items | limitTo:1">_x000D_
          <th ng-repeat="(key, val) in item">_x000D_
            {{key}}_x000D_
          </th>_x000D_
        </tr>_x000D_
      </thead>_x000D_
      <tbody>_x000D_
        <tr ng-repeat="item in items">_x000D_
          <td ng-repeat="(key, val) in item">_x000D_
            {{val}}_x000D_
          </td>_x000D_
        </tr>_x000D_
      </tbody>_x000D_
    </table>_x000D_
  </section>_x000D_
</body>

The limitTo:(n) filter is the key. Im still not sure if having multiple ng-repeat is an optimum way to go about it, but can't think of another alternative currently.

You don't need root to pull the apk files from /data/app. Sure, you might not have permissions to list the contents of that directory, but you can find the file locations of APKs with:

adb shell pm list packages -f

Then you can use adb pull:

adb pull <APK path from previous command>

and then aapt to get the information you want:

aapt dump badging <pulledfile.apk>

Here is example of using aggregation API. To complicate the case we're grouping by case-insensitive words from array property of the document.

db.articles.aggregate([
    {
        $match: {
            keywords: { $not: {$size: 0} }
        }
    },
    { $unwind: "$keywords" },
    {
        $group: {
            _id: {$toLower: '$keywords'},
            count: { $sum: 1 }
        }
    },
    {
        $match: {
            count: { $gte: 2 }
        }
    },
    { $sort : { count : -1} },
    { $limit : 100 }
]);

that give result such as

{ "_id" : "inflammation", "count" : 765 }
{ "_id" : "obesity", "count" : 641 }
{ "_id" : "epidemiology", "count" : 617 }
{ "_id" : "cancer", "count" : 604 }
{ "_id" : "breast cancer", "count" : 596 }
{ "_id" : "apoptosis", "count" : 570 }
{ "_id" : "children", "count" : 487 }
{ "_id" : "depression", "count" : 474 }
{ "_id" : "hiv", "count" : 468 }
{ "_id" : "prognosis", "count" : 428 }

A safe and long way:

1. git branch todelete
2. git checkout todelete
3. git add .
4. git commit -m "I did a bad thing, sorry"
5. git checkout develop
6. git branch -D todelete

    @staticmethod
    def my_static_method(): print("Life is short, you need Python")

test_class = CPerson
# print(dir(test_class))  # list all the fields and methods of your object

Many languages have variables, which are of a specific type and have a value. Python does not have variables; it has objects, and you use names to refer to these objects.

In other languages, when you say:

a = 1

then a (typically integer) variable changes its contents to the value 1.

In Python,

a = 1

means “use the name a to refer to the object 1”. You can do the following in an interactive Python session:

>>> type(1)
<type 'int'>

The function type is called with the object 1; since every object knows its type, it's easy for type to find out said type and return it.

Likewise, whenever you define a function

def funcname(param1, param2):

the function receives two objects, and names them param1 and param2, regardless of their types. If you want to make sure the objects received are of a specific type, code your function as if they are of the needed type(s) and catch the exceptions that are thrown if they aren't. The exceptions thrown are typically TypeError (you used an invalid operation) and AttributeError (you tried to access an inexistent member (methods are members too) ).

Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String s = formatter.format(date);

As a general rule, pop up blockers target windows that launch without user interaction. Usually a click event can open a window without it being blocked. (unless it's a really bad popup blocker)

Try launching after a click event

Checkout CefSharp .Net bindings, a project I started a while back that thankfully got picked up by the community and turned into something wonderful.

The project wraps the Chromium Embedded Framework and has been used in a number of major projects including Rdio's Windows client, Facebook Messenger for Windows and Github for Windows.

It features browser controls for WPF and Winforms and has tons of features and extension points. Being based on Chromium it's blisteringly fast too.

Grab it from NuGet: Install-Package CefSharp.Wpf or Install-Package CefSharp.WinForms

If I'm understanding it right...

If you want to start clean:

1) Manually delete your DB - wherever it is (I'm assuming you have your connection sorted), or empty it, but easier/safer is to delete it all together - as there is system __MigrationHistory table - you need that removed too.

2) Remove all migration files - which are under Migrations - and named like numbers etc. - remove them all,

3) Rebuild your project containing migrations (and the rest) - and make sure your project is set up (configuration) to build automatically (that sometimes may cause problems - but not likely for you),

4) Run Add-Migration Initial again - then Update-Database

Providing some other solution; we're also using react-native-image-picker; and the server side is using koa-multer; this set-up is working good:

ui

ImagePicker.showImagePicker(options, (response) => {
      if (response.didCancel) {}
      else if (response.error) {}
      else if (response.customButton) {}
      else {
        this.props.addPhoto({ // leads to handleAddPhoto()
          fileName: response.fileName,
          path: response.path,
          type: response.type,
          uri: response.uri,
          width: response.width,
          height: response.height,
        });
      }
    });

handleAddPhoto = (photo) => { // photo is the above object
    uploadImage({ // these 3 properties are required
      uri: photo.uri,
      type: photo.type,
      name: photo.fileName,
    }).then((data) => {
      // ...
    });
  }

client

export function uploadImage(file) { // so uri, type, name are required properties
  const formData = new FormData();
  formData.append('image', file);

  return fetch(`${imagePathPrefix}/upload`, { // give something like https://xx.yy.zz/upload/whatever
    method: 'POST',
    body: formData,
  }
  ).then(
    response => response.json()
  ).then(data => ({
    uri: data.uri,
    filename: data.filename,
  })
  ).catch(
    error => console.log('uploadImage error:', error)
  );
}

server

import multer from 'koa-multer';
import RouterBase from '../core/router-base';

const upload = multer({ dest: 'runtime/upload/' });

export default class FileUploadRouter extends RouterBase {
  setupRoutes({ router }) {
    router.post('/upload', upload.single('image'), async (ctx, next) => {
      const file = ctx.req.file;
      if (file != null) {
        ctx.body = {
          uri: file.filename,
          filename: file.originalname,
        };
      } else {
        ctx.body = {
          uri: '',
          filename: '',
        };
      }
    });
  }
}

A static library(.a) is a library that can be linked directly into the final executable produced by the linker,it is contained in it and there is no need to have the library into the system where the executable will be deployed.

A shared library(.so) is a library that is linked but not embedded in the final executable, so will be loaded when the executable is launched and need to be present in the system where the executable is deployed.

A dynamic link library on windows(.dll) is like a shared library(.so) on linux but there are some differences between the two implementations that are related to the OS (Windows vs Linux) :

A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined.

An SO library on Linux doesn't need special export statement to indicate exportable symbols, since all symbols are available to an interrogating process.

java.net.URLEncoder.encode(String s, String encoding) can help too. It follows the HTML form encoding application/x-www-form-urlencoded.

URLEncoder.encode(query, "UTF-8");

On the other hand, Percent-encoding (also known as URL encoding) encodes space with %20. Colon is a reserved character, so : will still remain a colon, after encoding.

Depends upon the version. The If operator in VB.NET 2008 is a ternary operator (as well as a null coalescence operator). This was just introduced, prior to 2008 this was not available. Here's some more info: Visual Basic If announcement

Example:

Dim foo as String = If(bar = buz, cat, dog)

[EDIT]

Prior to 2008 it was IIf, which worked almost identically to the If operator described Above.

Example:

Dim foo as String = IIf(bar = buz, cat, dog)

With literal syntax you can check as follows

static const NSString* kKeyToCheck = @"yourKey"
if (xyz[kKeyToCheck])
  NSLog(@"Key: %@, has Value: %@", kKeyToCheck, xyz[kKeyToCheck]);
else
 NSLog(@"Key pair do not exits for key: %@", kKeyToCheck); 

It would seem that any of the answers which implement an ORDER BY clause in the solution is missing the point, or does not actually understand what TOP returns to you.

TOP returns an unordered query result set which limits the record set to the first N records returned. (From an Oracle perspective, it is akin to adding a where ROWNUM < (N+1).

Any solution which uses an order, may return rows which also are returned by the TOP clause (since that data set was unordered in the first place), depending on what criteria was used in the order by

The usefulness of TOP is that once the dataset reaches a certain size N, it stops fetching rows. You can get a feel for what the data looks like without having to fetch all of it.

To implement BOTTOM accurately, it would need to fetch the entire dataset unordered and then restrict the dataset to the final N records. That will not be particularly effective if you are dealing with huge tables. Nor will it necessarily give you what you think you are asking for. The end of the data set may not necessarily be "the last rows inserted" (and probably won't be for most DML intensive applications).

Similarly, the solutions which implement an ORDER BY are, unfortunately, potentially disastrous when dealing with large data sets. If I have, say, 10 Billion records and want the last 10, it is quite foolish to order 10 Billion records and select the last 10.

The problem here, is that BOTTOM does not have the meaning that we think of when comparing it to TOP.

When records are inserted, deleted, inserted, deleted over and over and over again, some gaps will appear in the storage and later, rows will be slotted in, if possible. But what we often see, when we select TOP, appears to be sorted data, because it may have been inserted early on in the table's existence. If the table does not experience many deletions, it may appear to be ordered. (e.g. creation dates may be as far back in time as the table creation itself). But the reality is, if this is a delete-heavy table, the TOP N rows may not look like that at all.

So -- the bottom line here(pun intended) is that someone who is asking for the BOTTOM N records doesn't actually know what they're asking for. Or, at least, what they're asking for and what BOTTOM actually means are not the same thing.

So -- the solution may meet the actual business need of the requestor...but does not meet the criteria for being the BOTTOM.

df = pd.DataFrame({
'sp' : ['MM1', 'MM1', 'MM1', 'MM2', 'MM2', 'MM2', 'MM4', 'MM4','MM4'],
'mt' : ['S1', 'S1', 'S3', 'S3', 'S4', 'S4', 'S2', 'S2', 'S2'],
'val' : ['a', 'n', 'cb', 'mk', 'bg', 'dgb', 'rd', 'cb', 'uyi'],
'count' : [3,2,5,8,10,1,2,2,7]
})

df.groupby(['sp', 'mt']).apply(lambda grp: grp.nlargest(1, 'count'))

Here's what singleton is: http://en.wikipedia.org/wiki/Singleton_pattern

I don't know C#, but it's actually the same thing in all languages, only implementation differs.

You should generally avoid singleton when it's possible, but in some situations it's very convenient.

Sorry for my English ;)

When creating table in SQL Server make your table columns NVARCHAR instead of VARCHAR.

I wouldn't expect vertical tabs to need different Javascript from horizontal tabs. The only thing that would be different is the CSS for presenting the tabs and content on the page. JS for tabs generally does no more than show/hide/maybe load content.

This probably has the same table to other schema the reason why you're getting that error.

You need to drop first the child row then the parent row.

I found out that "git show --stat" is the best out of all here, gives you a brief summary of the commit, what files did you add and modify without giving you whole bunch of stuff, especially if you changed a lot files.

The argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove() call vs the drop() call.

More details in the docs.

This is for Ubunutu 14.04:

In file /etc/apache2/apache2.conf it should be as below without the directory name:

<Directory /home/username>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

And in file /etc/apache2/sites-available/000-default.conf you should include the custom directory name, i.e., www:

DocumentRoot /home/username/www

If it is not as above, it will give you an error when loading the server:

Forbidden You don't have permission to access / on this server

Use

git rev-parse --verify <tag>^{commit}

(which would return SHA-1 of a commit even for annotated tag).

git show-ref <tag> would also work if <tag> is not annotated. And there is always git for-each-ref (see documentation for details).

Add a method to c1 that will set 'someEvent' to null.

public class c1
{
    event EventHandler someEvent;
    public ResetSubscriptions() => someEvent = null;

let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "h:mm a"
let Date12 = dateFormatter.string(from: date!)

I had a problem with setting locale programmatically with devices that has Android OS N and higher. For me the solution was writing this code in my base activity:

(if you don't have a base activity then you should make these changes in all of your activities)

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(updateBaseContextLocale(base));
}

private Context updateBaseContextLocale(Context context) {
    String language = SharedPref.getInstance().getSavedLanguage();
    Locale locale = new Locale(language);
    Locale.setDefault(locale);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return updateResourcesLocale(context, locale);
    }

    return updateResourcesLocaleLegacy(context, locale);
}

@TargetApi(Build.VERSION_CODES.N)
private Context updateResourcesLocale(Context context, Locale locale) {
    Configuration configuration = context.getResources().getConfiguration();
    configuration.setLocale(locale);
    return context.createConfigurationContext(configuration);
}

@SuppressWarnings("deprecation")
private Context updateResourcesLocaleLegacy(Context context, Locale locale) {
    Resources resources = context.getResources();
    Configuration configuration = resources.getConfiguration();
    configuration.locale = locale;
    resources.updateConfiguration(configuration, resources.getDisplayMetrics());
    return context;
}

note that here it is not enough to call

createConfigurationContext(configuration)

you also need to get the context that this method returns and then to set this context in the attachBaseContext method.

I believe you can call a constructor from a constructor. It will compile and run. I recently saw someone do this and it ran on both Windows and Linux.

It just doesn't do what you want. The inner constructor will construct a temporary local object which gets deleted once the outer constructor returns. They would have to be different constructors as well or you would create a recursive call.

The select statement in the cost part of your select is returning more than one value. You need to add more where clauses, or use an aggregation.

The .bashrc file is in your user home directory (~/.bashrc or ~vagrant/.bashrc both resolve to the same path), inside the VM's filesystem. This file is invisible on the host machine, so you can't use any Windows editors to edit it directly.

You have two simple choices:

1. Learn how to use a console-based text editor. My favourite is vi (or vim), which takes 15 minutes to learn the basics and is much quicker for simple edits than anything else.

   vi .bashrc

2. Copy .bashrc out to /vagrant (which is a shared directory) and edit it using your Windows editors. Make sure not to save it back with any extensions.

   cp .bashrc /vagrant ... edit using your host machine ... cp /vagrant/.bashrc .

I'd recommend getting to know the command-line based editors. Once you're working inside the VM, it's best to stay there as otherwise you might just get confused.

You (the vagrant user) are the owner of your home .bashrc so you do have permissions to edit it.

Once edited, you can execute it by typing source .bashrc I prefer to logout and in again (there may be more than one file executed on login).

simple and working

goto C:\Program Files (x86)\Google\update

rename update folder name

simply do the select:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date) AND
((@day = 'Monday' AND (Monday = 1))
OR (@day = 'Tuesday' AND (Tuesday = 1))
OR (Wednesday = 1))

To list all of the screen sessions for a user, run the following command as that user:

screen -ls

To see all screen sessions on a specific machine you can do:

ls -laR /var/run/screen/

This is a rather brilliantly Unixy use of Unix Sockets wrapped in filesystem permissions to handle security, state, and streams.

getActionCommand()

Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.

IMO, this is useful in case you a single command-component to fire different commands based on it's state, and using this method your handler can execute the right lines of code.

JTextField has JTextField#setActionCommand(java.lang.String) method that you can use to set the command string used for action events generated by it.

getSource()

Returns: The object on which the Event initially occurred.

We can use getSource() to identify the component and execute corresponding lines of code within an action-listener. So, we don't need to write a separate action-listener for each command-component. And since you have the reference to the component itself, you can if you need to make any changes to the component as a result of the event.

If the event was generated by the JTextField then the ActionEvent#getSource() will give you the reference to the JTextField instance itself.

In certain cases, it might be necessary to restrict the display of a webpage to a document mode supported by an earlier version of Internet Explorer. You can do this by serving the page with an x-ua-compatible header. For more info, see Specifying legacy document modes.
- https://msdn.microsoft.com/library/cc288325

Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.

Make sure that you have checked it to work properly with the IE version you specify.

No there isn't. You can specify a background image but that's not the same thing.

Well, maybe I'm one of the few people here old enough to remember one of the big reasons why "only one return statement" was pushed so hard. It's so the compiler can emit more efficient code. For each function call, the compiler typically pushes some registers on the stack to preserve their values. This way, the function can use those registers for temporary storage. When the function returns, those saved registers have to be popped off the stack and back into the registers. That's one POP (or MOV -(SP),Rn) instruction per register. If you have a bunch of return statements, then either each one has to pop all the registers (which makes the compiled code bigger) or the compiler has to keep track of which registers might have been modified and only pop those (decreasing code size, but increasing compilation time).

One reason why it still makes sense today to try to stick with one return statement is ease of automated refactoring. If your IDE supports method-extraction refactoring (selecting a range of lines and turning them into a method), it's very difficult to do this if the lines you want to extract have a return statement in them, especially if you're returning a value.

Ok it turns out I was doing something stupid. I hadn't appended the new file name to the path.

I had

rootDirectory = "C:\\safesite_documents"

but it should have been

rootDirectory = "C:\\safesite_documents\\newFile.jpg" 

Sorry it was a stupid mistake as always.

You can't treat a PDF like an HTML document. Images can't "float" within a document and have things flow around them, or flow with surrounding text. FPDF allows you to embed html in a text block, but only because it parses the tags and replaces <i> and <b> and so on with Postscript equivalent commands. It's not smart enough to dynamically place an image.

In other words, you have to specify coordinates (and if you don't, the current location's coordinates will be used anyways).

Use a binding, like in this example:

<a href="#new-search" data-bind="click:SearchManager.bind($data,'1')">
  Search Manager
</a>

var ViewModelStructure = function () {
    var self = this;
    this.SearchManager = function (search) {
        console.log(search);
    };
}();

<html>
<head>
    <style type="text/css">
    .title {
        color: blue;
        text-decoration: bold;
        text-size: 1em;
    }

    .author {
        color: gray;
    }
    </style>
</head>
<body>
    <p>
    <span class="title">La super bonne</span>
    <span class="author">proposée par Jérém</span>
    </p>
</body>
</html>

On a side note, it would have been much easier to just do this.

select @EmpID = ID from dbo.Employee

Or

set @EmpID =(select id from dbo.Employee)

Note that the select query might return more than one value or rows. so you can write a select query that must return one row.

If you would like to add more columns to one variable(MS SQL), there is an option to use table defined variable

DECLARE @sampleTable TABLE(column1 type1)
INSERT INTO @sampleTable
SELECT columnsNumberEqualInsampleTable FROM .. WHERE ..

As table type variable do not exist in Oracle and others, you would have to define it:

DECLARE TYPE type_name IS TABLE OF (column_type | variable%TYPE | table.column%TYPE [NOT NULL] INDEX BY BINARY INTEGER;

-- Then to declare a TABLE variable of this type: variable_name type_name;

-- Assigning values to a TABLE variable: variable_name(n).field_name := 'some text';

-- Where 'n' is the index value

A little known (and little documented) fact about MATLAB's system() function: On unixoid systems it uses whatever interpreter is given in the environment variable SHELL or MATLAB_SHELL at the time of starting MATLAB. So if you start MATLAB with

SHELL='/usr/bin/python' matlab

any subsequent system() calls will use Python instead of your default shell as an interpreter.

Using jQuery:

function doSomething(element) {
    var form = $(element).closest("form").get().
    //do something with the form.
}

Kotlin

private lateinit var runnable: Runnable
override fun onCreate(savedInstanceState: Bundle?) {
    val handler = Handler()
    runnable = Runnable {
        // do your work
        handler.postDelayed(runnable, 2000)
    }
    handler.postDelayed(runnable, 2000)
}

Java

Runnable runnable;
Handler handler;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    handler = new Handler();
    runnable = new Runnable() {
        @Override
        public void run() {
            // do your work
            handler.postDelayed(this, 1000);
        }
    };
    handler.postDelayed(runnable, 1000);
}

If you are using a JAX-WS implementation for your client, such as Metro Web Services, the following code shows how to pass username and password in the HTTP headers:

 MyService port = new MyService();
 MyServiceWS service = port.getMyServicePort();

 Map<String, List<String>> credentials = new HashMap<String,List<String>>();

 credentials.put("username", Collections.singletonList("username"));
 credentials.put("password", Collections.singletonList("password"));

 ((BindingProvider)service).getRequestContext().put(MessageContext.HTTP_REQUEST_HEADERS, credentials);

Then subsequent calls to the service will be authenticated. Beware that the password is only encoded using Base64, so I encourage you to use other additional mechanism like client certificates to increase security.

I wanted similar richness in colors for HTML elements, I was surprised to find that CSS now supports hsl() colors, so a full solution for me is below:

Also see How to automatically generate N "distinct" colors? for more alternatives more similar to this.

function colorByHashCode(value) {_x000D_
    return "<span style='color:" + value.getHashCode().intToHSL() + "'>" + value + "</span>";_x000D_
}_x000D_
String.prototype.getHashCode = function() {_x000D_
    var hash = 0;_x000D_
    if (this.length == 0) return hash;_x000D_
    for (var i = 0; i < this.length; i++) {_x000D_
        hash = this.charCodeAt(i) + ((hash << 5) - hash);_x000D_
        hash = hash & hash; // Convert to 32bit integer_x000D_
    }_x000D_
    return hash;_x000D_
};_x000D_
Number.prototype.intToHSL = function() {_x000D_
    var shortened = this % 360;_x000D_
    return "hsl(" + shortened + ",100%,30%)";_x000D_
};_x000D_
_x000D_
document.body.innerHTML = [_x000D_
  "javascript",_x000D_
  "is",_x000D_
  "nice",_x000D_
].map(colorByHashCode).join("<br/>");

span {_x000D_
  font-size: 50px;_x000D_
  font-weight: 800;_x000D_
}

In HSL its Hue, Saturation, Lightness. So the hue between 0-359 will get all colors, saturation is how rich you want the color, 100% works for me. And Lightness determines the deepness, 50% is normal, 25% is dark colors, 75% is pastel. I have 30% because it fit with my color scheme best.

You can use the following example to reverse the contents in an array:

#include <iostream>

int main()
{
    int n, x;

    // order value for var x
    cin >> x;  

    // create array and the value for array is value var x
    int arr[x];

    // loop for insert values for array by reverse  
    for(int i=x; i > 0; i--) {

        // var i is number of elements in array 
        cin >> n;
        arr[i - 1] = n;
    }

    // show element in array
    for(int l = 0; l < x; l++) {
        cout<<arr[l]<<endl;
    }

    return 0;        
}

A useful extension is to collect the results in a Dictionary for fast lookup (e.g. in a loop):

var resultDict = _dbContext.Projects
    .Where(p => p.Status == ProjectStatus.Active)
    .GroupBy(f => f.Country)
    .Select(g => new { country = g.Key, count = g.Count() })
    .ToDictionary(k => k.country, i => i.count);

Here is one that works for multiple duplicates and you don't need to specify any values:

List = ['A', 'B', 'A', 'C', 'E', 'B'] # duplicate two 'A's two 'B's

ix_list = []
for i in range(len(List)):
    try:
        dup_ix = List[(i+1):].index(List[i]) + (i + 1) # dup onwards + (i + 1)
        ix_list.extend([i, dup_ix]) # if found no error, add i also
    except:
        pass
    
ix_list.sort()

print(ix_list)

In C, the order that you define things often matters. Either move the definition of outchar to the top, or provide a prototype at the top, like this:

#include <stdio.h> #include <stdlib.h>  void outchar(char ch);  int main() {     outchar('A');     outchar('B');     outchar('C');     return 0; }  void outchar(char ch) {     printf("%c", ch); } 

Also, you should be specifying the return type of every function. I added that for you.

In Spring properties files, you can't just specify a number for this property. You also need to specify a unit. So you can say spring.mvc.async.request-timeout=5000ms or spring.mvc.async.request-timeout=5s, both of which will give you a 5-second timeout.

This should fulfill your requirements.

Updated Answer

Trying to open multiple panels of a collapse control that is setup as an accordion i.e. with the data-parent attribute set, can prove quite problematic and buggy (see this question on multiple panels open after programmatically opening a panel)

Instead, the best approach would be to:

1. Allow each panel to toggle individually
2. Then, enforce the accordion behavior manually where appropriate.

To allow each panel to toggle individually, on the data-toggle="collapse" element, set the data-target attribute to the .collapse panel ID selector (instead of setting the data-parent attribute to the parent control. You can read more about this in the question Modify Twitter Bootstrap collapse plugin to keep accordions open.

Roughly, each panel should look like this:

<div class="panel panel-default">
   <div class="panel-heading">
         <h4 class="panel-title"
             data-toggle="collapse" 
             data-target="#collapseOne">
             Collapsible Group Item #1
         </h4>
    </div>
    <div id="collapseOne" 
         class="panel-collapse collapse">
        <div class="panel-body"></div>
    </div>
</div>

To manually enforce the accordion behavior, you can create a handler for the collapse show event which occurs just before any panels are displayed. Use this to ensure any other open panels are closed before the selected one is shown (see this answer to multiple panels open). You'll also only want the code to execute when the panels are active. To do all that, add the following code:

$('#accordion').on('show.bs.collapse', function () {
    if (active) $('#accordion .in').collapse('hide');
});

Then use show and hide to toggle the visibility of each of the panels and data-toggle to enable and disable the controls.

$('#collapse-init').click(function () {
    if (active) {
        active = false;
        $('.panel-collapse').collapse('show');
        $('.panel-title').attr('data-toggle', '');
        $(this).text('Enable accordion behavior');
    } else {
        active = true;
        $('.panel-collapse').collapse('hide');
        $('.panel-title').attr('data-toggle', 'collapse');
        $(this).text('Disable accordion behavior');
    }
});

Working demo in jsFiddle

To build off what Martjin was saying. I'd use string interpolation/formatting.

In Python 2.x which seems to be what you're using due to the lack of parenthesis around the print function you do:

print 'Value is "%d"' % value

In Python 3.x you'd use the format method instead, so you're code would look like this.

message = 'Value is "{}"'
print(message.format(value))

To use shorthand to get the direction:

int direction = column == 0
                ? 0
                : (column == _gridSize - 1 ? 1 : rand.Next(2));

To simplify the code entirely:

if (column == gridSize - 1 || rand.Next(2) == 1)
{
}
else
{
}

If the copy command is run from within a batch job you do not need to use the /Y switch: it will overwrite existing files.

Chrome Dev Tool's "Network" tool now allows you to import HAR files by drag-and-dropping into the window.

This powershell example looks for all instances of the string "\foo\" in a folder and its subfolders, replaces "\foo\" with "\bar\" AND DOES NOT REWRITE files that don't contain the string "\foo\" This way you don't destroy the file last update datetime stamps where the string was not found:

Get-ChildItem  -Path C:\YOUR_ROOT_PATH\*.* -recurse 
 | ForEach {If (Get-Content $_.FullName | Select-String -Pattern '\\foo\\') 
           {(Get-Content $_ | ForEach {$_ -replace '\\foo\\', '\bar\'}) | Set-Content $_ }
           }

Shallow copy with copy.copy()

#!/usr/bin/env python3

import copy

class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]

# It copies.
c = C()
d = copy.copy(c)
d.x = [3]
assert c.x == [1]
assert d.x == [3]

# It's shallow.
c = C()
d = copy.copy(c)
d.x[0] = 3
assert c.x == [3]
assert d.x == [3]

Deep copy with copy.deepcopy()

#!/usr/bin/env python3
import copy
class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]
c = C()
d = copy.deepcopy(c)
d.x[0] = 3
assert c.x == [1]

I run this command within a bash script, in particular to submit SGE jobs and batch process things:

/Path_to_matlab -nodisplay -nosplash -nodesktop < m_file.m

You can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:

>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a[-9:]
[4, 5, 6, 7, 8, 9, 10, 11, 12]

the important line is a[-9:]

It depends on how you tested it, and possibly on differences in the TCP stack implementation of the personal computer and the server.

For example, if your sendall always completes immediately (or very quickly) on the personal computer, the connection may simply never have broken during sending. This is very likely if your browser is running on the same machine (since there is no real network latency).

In general, you just need to handle the case where a client disconnects before you're finished, by handling the exception.

Remember that TCP communications are asynchronous, but this is much more obvious on physically remote connections than on local ones, so conditions like this can be hard to reproduce on a local workstation. Specifically, loopback connections on a single machine are often almost synchronous.

There are 2 ways to configure custom error pages for ASP.NET sites:

1. Internet Information Services (IIS) Manager (the GUI)
2. web.config file

This article explains how to do each:

• How To Set Up Custom Error Pages In IIS 7.5 With ASP.NET

The reason your error.aspx page is not displaying might be because you have an error in your web.config. Try this instead:

<configuration>
   <system.web>
      <customErrors defaultRedirect="error.aspx" mode="RemoteOnly">
         <error statusCode="404" redirect="error.aspx"/>

There is one big difference between malloc and new. malloc allocates memory. This is fine for C, because in C, a lump of memory is an object.

In C++, if you're not dealing with POD types (which are similar to C types) you must call a constructor on a memory location to actually have an object there. Non-POD types are very common in C++, as many C++ features make an object automatically non-POD.

new allocates memory and creates an object on that memory location. For non-POD types this means calling a constructor.

If you do something like this:

non_pod_type* p = (non_pod_type*) malloc(sizeof *p);

The pointer you obtain cannot be dereferenced because it does not point to an object. You'd need to call a constructor on it before you can use it (and this is done using placement new).

If, on the other hand, you do:

non_pod_type* p = new non_pod_type();

You get a pointer that is always valid, because new created an object.

Even for POD types, there's a significant difference between the two:

pod_type* p = (pod_type*) malloc(sizeof *p);
std::cout << p->foo;

This piece of code would print an unspecified value, because the POD objects created by malloc are not initialised.

With new, you could specify a constructor to call, and thus get a well defined value.

pod_type* p = new pod_type();
std::cout << p->foo; // prints 0

If you really want it, you can use use new to obtain uninitialised POD objects. See this other answer for more information on that.

Another difference is the behaviour upon failure. When it fails to allocate memory, malloc returns a null pointer, while new throws an exception.

The former requires you to test every pointer returned before using it, while the later will always produce valid pointers.

For these reasons, in C++ code you should use new, and not malloc. But even then, you should not use new "in the open", because it acquires resources you need to release later on. When you use new you should pass its result immediately into a resource managing class:

std::unique_ptr<T> p = std::unique_ptr<T>(new T()); // this won't leak

Each class will use its own classloader to load other classes. So if ClassA.class references ClassB.class then ClassB needs to be on the classpath of the classloader of ClassA, or its parents.

The thread context classloader is the current classloader for the current thread. An object can be created from a class in ClassLoaderC and then passed to a thread owned by ClassLoaderD. In this case the object needs to use Thread.currentThread().getContextClassLoader() directly if it wants to load resources that are not available on its own classloader.

It does work as below:

public interface UserRepository extends JpaRepository<User, Long> {
    @Query(value = "select * from (select (@rowid\\:=@rowid+1) as RN, u.* from USERS u, (SELECT @rowid\\:=0) as init where  LASTNAME = ?1) as total"+
        "where RN between ?#{#pageable.offset-1} and ?#{#pageable.offset + #pageable.pageSize}",
    countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
    nativeQuery = true)
    Page<User> findByLastname(String lastname, Pageable pageable);
}

var requiredPath = Path.GetDirectoryName(Path.GetDirectoryName(
System.IO.Path.GetDirectoryName( 
      System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase )));

Assuming "current version" is the working directory (uncommitted modifications) and "last version" is HEAD (last committed modifications for the current branch), simply do

git diff HEAD

Credit for the following goes to user Cerran.

And if you always skip the staging area with -a when you commit, then you can simply use git diff.

Summary

1. git diff shows unstaged changes.
2. git diff --cached shows staged changes.
3. git diff HEAD shows all changes (both staged and unstaged).

Another solution could be via pandas Series:

import pandas as pd

a = pd.Series([-2, 1, 5, 3, 8, 5, 6])
b = [1, 2, 5]
c = a[b]

You can then convert c back to a list if you want:

c = list(c)

another alternative is to use a form replacement script/library. They usually hide the original element and replace them with a div or span, which you can style in whatever way you like.

Examples are:

The JPA @Column Annotation

The nullable attribute of the @Column annotation has two purposes:

• it's used by the schema generation tool
• it's used by Hibernate during flushing the Persistence Context

Schema Generation Tool

The HBM2DDL schema generation tool translates the @Column(nullable = false) entity attribute to a NOT NULL constraint for the associated table column when generating the CREATE TABLE statement.

As I explained in the Hibernate User Guide, it's better to use a tool like Flyway instead of relying on the HBM2DDL mechanism for generating the database schema.

Persistence Context Flush

When flushing the Persistence Context, Hibernate ORM also uses the @Column(nullable = false) entity attribute:

new Nullability( session ).checkNullability( values, persister, true );

If the validation fails, Hibernate will throw a PropertyValueException, and prevents the INSERT or UPDATE statement to be executed needesly:

if ( !nullability[i] && value == null ) {
    //check basic level one nullablilty
    throw new PropertyValueException(
            "not-null property references a null or transient value",
            persister.getEntityName(),
            persister.getPropertyNames()[i]
        );    
}

The Bean Validation @NotNull Annotation

The @NotNull annotation is defined by Bean Validation and, just like Hibernate ORM is the most popular JPA implementation, the most popular Bean Validation implementation is the Hibernate Validator framework.

When using Hibernate Validator along with Hibernate ORM, Hibernate Validator will throw a ConstraintViolation when validating the entity.

Based on git diff --name-status I wrote the git-diffview git extension that renders a hierarchical tree view of what changed between two paths.

There's a well documented answer to your question at this url:

http://blogs.technet.com/b/heyscriptingguy/archive/2005/02/18/how-can-i-list-the-files-in-a-folder-and-all-its-subfolders.aspx

The answer shown at that URL is kind of complicated and uses WMI (Windows Management Instrumentation) to iterate through files and folders. But if you do a lot of Windows administration, it's worth the effort to learn WMI.

I'm posting this now in case you need something right now; but I think I used to use a filesystemobject based approach, and I'll look for some example, and I'll post it later if I find it.

I hope this is helpful.

The exception occurred due to the fact that any of the inner classes or other referenced classes didn't implement the serializable implementation. So make sure that all the referenced classes must implement the serializable implementation.

Step 1: Goto https://projectlombok.org/download and click on 1.18.2

Step 2: Place your jar file in java installation path in my case it is C:\Program Files\Java\jdk-10.0.1\lib

step 3: Open your Eclipse IDE folder where you have in your PC.

Step 4: Add the place where I added then open your IDE it will open without any errors.

If you copy paste your project the .angular-cli.json you wil not find this file try to create a new file with the same name and add the code and it wil work.

You are trying to play a .mp3 as if it were a .wav.

You could try using pydub to convert it to .wav format, and then feed that into pyAudio.

Example:

from pydub import AudioSegment

song = AudioSegment.from_mp3("original.mp3")
song.export("final.wav", format="wav")

Alternatively, use pygame, as mentioned in the other answer.

and with --outdated as an extra argument, you will get the Current and Latest versions of the packages you are using :

$ pip list --outdated
distribute (Current: 0.6.34 Latest: 0.7.3)
django-bootstrap3 (Current: 1.1.0 Latest: 4.3.0)
Django (Current: 1.5.4 Latest: 1.6.4)
Jinja2 (Current: 2.6 Latest: 2.8)

So combining with AdamKG 's answer :

$ pip list --outdated | grep Jinja2
Jinja2 (Current: 2.6 Latest: 2.8)

When I needed HTML to PDF conversion earlier this year, I tried the trial of Winnovative HTML to PDF converter (I think ExpertPDF is the same product, too). It worked great so we bought a license at that company. I don't go into it too in depth after that.

There is another instance still same error will shown after you doing everything above mentioned. When you change your codes accordingly mentioned solutions make sure to keep originals. So you can easily go back. So go and again check dispatcher-servelet configuration file's base package location. Is it scanning all relevant packages when you running application.

<context:component-scan base-package="your.pakage.path.here"/>

There seems to be a lot of confusion here. The answers I see so far don't correctly enforce the 1+ number/1+ lowercase/1+ uppercase rule, meaning that passwords like abc123, 123XYZ, or AB*&^# would still be accepted. Preventing all-lowercase, all-caps, or all-digits is not enough; you have to enforce the presence of at least one of each.

Try the following:

^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).{8,15}$

If you also want to require at least one special character (which is probably a good idea), try this:

^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[^\da-zA-Z]).{8,15}$

The .{8,15} can be made more restrictive if you wish (for example, you could change it to \S{8,15} to disallow whitespace), but remember that doing so will reduce the strength of your password scheme.

I've tested this pattern and it works as expected. Tested on ReFiddle here: http://refiddle.com/110

Edit: One small note, the easiest way to do this is with 3 separate regexes and the string's Length property. It's also easier to read and maintain, so do it that way if you have the option. If this is for validation rules in markup, though, you're probably stuck with a single regex.

Assume you were:

1. Reading a network file and got disconnected.
2. Reading a local file that was no longer available.
3. Using some stream to read data and some other process closed the stream.
4. Trying to read/write a file, but don't have permission.
5. Trying to write to a file, but disk space was no longer available.

There are many more examples, but these are the most common, in my experience.

Simple ... use OSGi. In OSGi you can iterate over your Bundle's entries with findEntries and findPaths.

I've always used Ctrl + Home (start of file) and Ctrl + End (end of file).

Works in both insert and nav modes.

It appears the problem is that a user created via the method described in the mongo docs does not have permission to connect to the default database (test), even if that user was created with the "userAdminAnyDatabase" and "dbAdminAnyDatabase" roles.

Just convert the string to uppercase or to lower case to match the search criteria, i.e:

string title = "ASTRINGTOTEST"; title.ToLower().Contains("string");

Just for sake of completeness (maybe someone else won't have to implement it from scratch):

We've implemented our own small library, as everyone else. It's supposed to make things easier, so that our developers don't have to reimplement it each time. It would be great if spring security would provide support of rbac out of the box, as this approach is much better than the default permission based one.

Have a look at Github (OSS, MIT license) to see if it suits your needs. It's basically only addressing the role <-> privileges mapping. The missing piece, you'll have to provide on your own is basically the user <-> roles mapping, e.g. by mapping groups (racf/ad groups) to roles (1:1) or by implementing an additional mapping. That one's different in each project, so it doesn't make sense to provide some implementation.

We've basically used this internally, so that we can start with rbac from the beginning. We can still replace it with some other implementation later on, if the application is growing, but it's important for us to get the setup right at the beginning.

If you don't use rbac, there's a good chance, that the permissions are scattered throughout the codebase and you'll have a hard time to extract/group those (into roles) later on. The generated graphs do also help to reason about it/restructure it later on.

Old answer:

Try using this URL: http://translate.google.com/translate_tts?tl=en&q=Hello%20World It will automatically generate a wav file which you can easily get with an HTTP request through any .net programming.

Edit:

Ohh Google, you thought you could prevent people from using your wonderful service with flimsy http header verification.

Here is a solution to get a response in multiple languages (I'll try to add more as we go):

NodeJS

// npm install `request`
const fs = require('fs');
const request = require('request');
const text = 'Hello World';

const options = {
    url: `https://translate.google.com/translate_tts?ie=UTF-8&q=${encodeURIComponent(text)}&tl=en&client=tw-ob`,
    headers: {
        'Referer': 'http://translate.google.com/',
        'User-Agent': 'stagefright/1.2 (Linux;Android 5.0)'
    }
}

request(options)
    .pipe(fs.createWriteStream('tts.mp3'))

Curl

curl 'https://translate.google.com/translate_tts?ie=UTF-8&q=Hello%20Everyone&tl=en&client=tw-ob' -H 'Referer: http://translate.google.com/' -H 'User-Agent: stagefright/1.2 (Linux;Android 5.0)' > google_tts.mp3

Note that the headers are based on @Chris Cirefice's example, if they stop working at some point I'll attempt to recreate conditions for this code to function. All credits for the current headers go to him and the wonderful tool that is WireShark. (also thanks to Google for not patching this)

By default, nvarchar(MAX) values are stored exactly the same as nvarchar(4000) values would be, unless the actual length exceed 4000 characters; in that case, the in-row data is replaced by a pointer to one or more seperate pages where the data is stored.

If you anticipate data possibly exceeding 4000 character, nvarchar(MAX) is definitely the recommended choice.

Iterator is super class of ListIterator.

Here are the differences between them:

1. With iterator you can move only forward, but with ListIterator you can move backword also while reading the elements.
2. With ListIterator you can obtain the index at any point while traversing, which is not possible with iterators.
3. With iterator you can check only for next element available or not, but in listiterator you can check previous and next elements.
4. With listiterator you can add new element at any point of time, while traversing. Not possible with iterator.
5. With listiterator you can modify an element while traversing, which is not possible with iterator.

Iterator look and feel:

 public interface Iterator<E> {
    boolean hasNext();
    E next();
    void remove(); //optional-->use only once with next(), 
                         dont use it when u use for:each
    }

ListIterator look and feel:

public interface ListIterator<E> extends Iterator<E> {
    boolean hasNext();
    E next();
    boolean hasPrevious();
    E previous();
    int nextIndex();
    int previousIndex();
    void remove(); //optional
    void set(E e); //optional
    void add(E e); //optional
}

$(this) is a jQuery object that is wrapping the DOM element this and jQuery objects don't have id properties. You probably want just this.id to get the id attribute of the clicked element.

In PostgreSQL there is no merge command, and actually writing it is not trivial - there are actually strange edge cases that make the task "interesting".

The best (as in: working in the most possible conditions) approach, is to use function - such as one shown in manual (merge_db).

If you don't want to use function, you can usually get away with:

updated = db.execute(UPDATE ... RETURNING 1)
if (!updated)
  db.execute(INSERT...)

Just remember that it is not fault proof and it will fail eventually.

Mongo includes a mongoexport utility (see docs) which can dump a collection. This utility uses the native libmongoclient and is likely the fastest method.

mongoexport -d <database> -c <collection_name>

Also helpful:

-o: write the output to file, otherwise standard output is used (docs)

--jsonArray: generates a valid json document, instead of one json object per line (docs)

--pretty: outputs formatted json (docs)

 scrollView.postDelayed(new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    },1000);

You'd use the corresponding method getVisibility(). Method names prefixed with 'get' and 'set' are Java's convention for representing properties. Some language have actual language constructs for properties but Java isn't one of them. So when you see something labeled 'setX', you can be 99% certain there's a corresponding 'getX' that will tell you the value.

You can convert the value to a date using a formula like this, next to the cell:

=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2))

Where A1 is the field you need to convert.

Alternatively, you could use this code in VBA:

Sub ConvertYYYYMMDDToDate()
   Dim c As Range
   For Each c In Selection.Cells
       c.Value = DateSerial(Left(c.Value, 4), Mid(c.Value, 5, 2), Right(c.Value, 2))
       'Following line added only to enforce the format.
       c.NumberFormat = "mm/dd/yyyy"
   Next
End Sub

Just highlight any cells you want fixed and run the code.

Note as RJohnson mentioned in the comments, this code will error if one of your selected cells is empty. You can add a condition on c.value to skip the update if it is blank.

I tried changing the padding and margin and well as the width and height, and then finally found that if you just increase the scale it'll work:

input[type=checkbox] {
    transform: scale(1.5);
}

params also allows you to call the method with a single argument.

private static int Foo(params int[] args) {
    int retVal = 0;
    Array.ForEach(args, (i) => retVal += i);
    return retVal;
}

i.e. Foo(1); instead of Foo(new int[] { 1 });. Can be useful for shorthand in scenarios where you might need to pass in a single value rather than an entire array. It still is handled the same way in the method, but gives some candy for calling this way.

To store the third line into a variable, use below syntax:

variable=`echo "$1" | sed '3q;d' urfile`

To store the changed line into a variable, use below syntax: variable=echo 'overflow' | sed -e "s/over/"OVER"/g" output:OVERflow

Another way to throw an exceptions is assert. You can use assert to verify a condition is being fulfilled if not then it will raise AssertionError. For more details have a look here.

def avg(marks):
    assert len(marks) != 0,"List is empty."
    return sum(marks)/len(marks)

mark2 = [55,88,78,90,79]
print("Average of mark2:",avg(mark2))

mark1 = []
print("Average of mark1:",avg(mark1))

No Gemfile.lock means:

• new contributors cannot run tests because weird things fail, so they won't contribute or get failing PRs ... bad first experience.
• you cannot go back to a x year old project and fix a bug without having to update/rewrite the project if you lost your local Gemfile.lock

-> Always check in Gemfile.lock, make travis delete it if you want to be extra thorough https://grosser.it/2015/08/14/check-in-your-gemfile-lock/

You can do this if you have the id to check it

document.getElementById('ElementId').checked = false

And this to uncheck

document.getElementById('ElementId').checked = true

What do you want to do with the text? Is the file small enough to fit into memory? I would try to find the simplest way to handle the file for your needs. The FileUtils library is very handle for this.

for(String line: FileUtils.readLines("my-text-file"))
    System.out.println(line);

You can also use txml. It can parse into a DOM made of simple objects and stringify. In the result, the content will be trimmed. So formating of the original with whitespaces will be lost. But this could be used very good to minify HTML.

const xml = require('txml');
const data = `
<tag>tag content</tag>
<tag2>another content</tag2>
<tag3>
  <insideTag>inside content</insideTag>
  <emptyTag />
</tag3>`;

const dom = xml(data); // the dom can be JSON.stringified

xml.stringify(dom); // this will return the dom into an xml-string

Disclaimer: I am the author of txml, the fastest xml parser in javascript.

You say you want to delete any column with the title "Percent Margin of Error" so let's try to make this dynamic instead of naming columns directly.

Sub deleteCol()

On Error Resume Next

Dim wbCurrent As Workbook
Dim wsCurrent As Worksheet
Dim nLastCol, i As Integer

Set wbCurrent = ActiveWorkbook
Set wsCurrent = wbCurrent.ActiveSheet
'This next variable will get the column number of the very last column that has data in it, so we can use it in a loop later
nLastCol = wsCurrent.Cells.Find("*", LookIn:=xlValues, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column

'This loop will go through each column header and delete the column if the header contains "Percent Margin of Error"
For i = nLastCol To 1 Step -1
    If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) > 0 Then
        wsCurrent.Columns(i).Delete Shift:=xlShiftToLeft
    End If
Next i

End Sub

With this you won't need to worry about where you data is pasted/imported to, as long as the column headers are in the first row.

EDIT: And if your headers aren't in the first row, it would be a really simple change. In this part of the code: If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) change the "1" in Cells(1, i) to whatever row your headers are in.

EDIT 2: Changed the For section of the code to account for completely empty columns.

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

TextView gravity works as per your parent layout.

LinearLayout:

If you use LinearLayout then you will find two gravity attribute android:gravity & android:layout_gravity

android:gravity : represent layout potion of internal text of TextView while android:layout_gravity : represent TextView position in parent view.

If you want to set text horizontally & vertically center then use below code this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="300dp"
    android:background="@android:color/background_light"
    android:layout_height="300dp">

    <TextView
        android:layout_width="match_parent"
        android:text="Hello World!"
        android:gravity="center_horizontal"
        android:layout_gravity="center_vertical"
        android:layout_height="wrap_content"
    />
</LinearLayout>

RelativeLayout:

Using RelativeLayout you can use below property in TextView

android:gravity="center" for text center in TextView.

android:gravity="center_horizontal" inner text if you want horizontally centered.

android:gravity="center_vertical" inner text if you want vertically centered.

android:layout_centerInParent="true" if you want TextView in center position of parent view. android:layout_centerHorizontal="true" if you want TextView in horizontally center of parent view. android:layout_centerVertical="true" if you want TextView in vertically center of parent view.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="300dp"
    android:background="@android:color/background_light"
    android:layout_height="300dp">

    <TextView
        android:layout_width="match_parent"
        android:text="Hello World!"
        android:gravity="center"
        android:layout_centerInParent="true"
        android:layout_height="wrap_content"
    />
</RelativeLayout>

<div style="height: 100px;"> </div>

OR

<div id="foo"/> and set the style as #foo { height: 100px; }
<div class="bar"/> and set the style as .bar{ height: 100px;  }

Adding onclick="this.checked=true"Solve my problem:
Example:

<input type="checkbox" id="scales" name="feature[]" value="scales" checked="checked" onclick="this.checked=true" />

You can also find Toggle Line Numbers under View on the top toolbar of the Jupyter notebook in your browser. This adds/removes the lines numbers in all notebook cells.

For me, Esc+l only added/removed the line numbers of the active cell.

Ran to the same issue, Assuming your using anaconda3 and your using a venv with >= python=3.6:

python -m pip install keras
sudo python -m pip install --user tensorflow

An alternative to fsolve is root:

import numpy as np
from scipy.optimize import root    

def your_funcs(X):

    x, y = X
    # all RHS have to be 0
    f = [x + y**2 - 4,
         np.exp(x) + x * y - 3]

    return f

sol = root(your_funcs, [1.0, 1.0])
print(sol.x)

This will print

[0.62034452 1.83838393]

If you then check

print(your_funcs(sol.x))

you obtain

[4.4508396968012676e-11, -1.0512035686360832e-11]

confirming that the solution is correct.

I made a slight improvement on the accepted answer, it allows to check with case-sensitive/case-insensitive matching, and is a method attached to the string object:

String.prototype.count = function(lit, cis) {
    var m = this.toString().match(new RegExp(lit, ((cis) ? "gi" : "g")));
    return (m != null) ? m.length : 0;
}

lit is the string to search for ( such as 'ex' ), and cis is case-insensitivity, defaulted to false, it will allow for choice of case insensitive matches.

var amount_of_os = 'I love StackOverflow.com'.count('o');

amount_of_os would be equal to 2.

var amount_of_os = 'I love StackOverflow.com'.count('o', true);

This time, amount_of_os would be equal to 3, since the capital O from the string gets included in the search.

Well, I looked it up on wikipedia, and they have this to say:

C, however, has only one right shift operator, >>. Many C compilers choose which right shift to perform depending on what type of integer is being shifted; often signed integers are shifted using the arithmetic shift, and unsigned integers are shifted using the logical shift.

So it sounds like it depends on your compiler. Also in that article, note that left shift is the same for arithmetic and logical. I would recommend doing a simple test with some signed and unsigned numbers on the border case (high bit set of course) and see what the result is on your compiler. I would also recommend avoiding depending on it being one or the other since it seems C has no standard, at least if it is reasonable and possible to avoid such dependence.

In order to access private fields, you need to get them from the class's declared fields and then make them accessible:

Field f = obj.getClass().getDeclaredField("stuffIWant"); //NoSuchFieldException
f.setAccessible(true);
Hashtable iWantThis = (Hashtable) f.get(obj); //IllegalAccessException

EDIT: as has been commented by aperkins, both accessing the field, setting it as accessible and retrieving the value can throw Exceptions, although the only checked exceptions you need to be mindful of are commented above.

The NoSuchFieldException would be thrown if you asked for a field by a name which did not correspond to a declared field.

obj.getClass().getDeclaredField("misspelled"); //will throw NoSuchFieldException

The IllegalAccessException would be thrown if the field was not accessible (for example, if it is private and has not been made accessible via missing out the f.setAccessible(true) line.

The RuntimeExceptions which may be thrown are either SecurityExceptions (if the JVM's SecurityManager will not allow you to change a field's accessibility), or IllegalArgumentExceptions, if you try and access the field on an object not of the field's class's type:

f.get("BOB"); //will throw IllegalArgumentException, as String is of the wrong type

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

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

I hope it useful for you!

The best thing out there is Memory Analyzer (MAT), IntelliJ does not have any bundled heap dump analyzer.

Nobody seems to address the case of summing elements of a vector that can have NaN values in it, e.g. numerical_limits<double>::quite_NaN()

I usually loop through the elements and bluntly check.

vector<double> x;

//...

size_t n = x.size();

double sum = 0;

for (size_t i = 0; i < n; i++){

  sum += (x[i] == x[i] ? x[i] : 0);

}

It's not fancy at all, i.e. no iterators or any other tricks but I this is how I do it. Some times if there are other things to do inside the loop and I want the code to be more readable I write

double val = x[i];

sum += (val == val ? val : 0);

//...

inside the loop and re-use val if needed.

Simpler way:

.then( resp=> {
  let resultFromDb= Object.values(resp)[0]
  console.log(resultFromDb)
}

In my example I received an object in response. When I use Object.values I have the value of the property as a response, however it comes inside an array, using [0] access the first index of this array, now i have the value to use it where I need it.

You can find more info about what limitations browsers will likely add to mitigate this and what IETF is doing about it as well as why this is needed at IETF SPEC on IP handling

For MacOS

1. Open terminal

2. Run the below code and hit enter

    sudo kill $(sudo lsof -t -i:4200)
   

ToAddress = "[email protected]"
ToAddress1 = "[email protected]"
ToAddress2 = "[email protected]"
MessageSubject = "It works!."
Set ol = CreateObject("Outlook.Application")
Set newMail = ol.CreateItem(olMailItem)
newMail.Subject = MessageSubject
newMail.RecipIents.Add(ToAddress)
newMail.RecipIents.Add(ToAddress1)
newMail.RecipIents.Add(ToAddress2)
newMail.Send

A quick-and-dirty approach:

function exec_sql_from_file($path, PDO $pdo) {
    if (! preg_match_all("/('(\\\\.|.)*?'|[^;])+/s", file_get_contents($path), $m))
        return;

    foreach ($m[0] as $sql) {
        if (strlen(trim($sql)))
            $pdo->exec($sql);
    }
}

Splits at reasonable SQL statement end points. There is no error checking, no injection protection. Understand your use before using it. Personally, I use it for seeding raw migration files for integration testing.

While I agree with everyone else, if you are dead set on using frames anyway, you can just do index.html in XHTML and then do the contents of the frames in HTML5.

df<- dplyr::select ( df,A,B,C)

Also, you can assign a different name to the newly created data

data<- dplyr::select ( df,A,B,C)

I know this is an old question, but i faced this issue myself redesigning a website. Troy Dalmasso got me thinking. He makes a good point. So, i started to see if i could get it working without a container div.

I could when i set the width of the body. In my case to 960px.

This is the css i use:

html {
  text-align:center;
}

body {
  margin: 0 auto;
  width: 960px;
}

This nicely centers the inline-blocks which also have a fixed width.

Hope this is of use to anyone.

You can iterate over a dictionary and grab an index with for-in and enumerate (like others have said, there is no guarantee it will come out ordered like below)

let dict = ["c": 123, "d": 045, "a": 456]

for (index, entry) in enumerate(dict) {
    println(index)   // 0       1        2
    println(entry)   // (d, 45) (c, 123) (a, 456)
}

If you want to sort first..

var sortedKeysArray = sorted(dict) { $0.0 < $1.0 }
println(sortedKeysArray)   // [(a, 456), (c, 123), (d, 45)]

var sortedValuesArray = sorted(dict) { $0.1 < $1.1 }
println(sortedValuesArray) // [(d, 45), (c, 123), (a, 456)]

then iterate.

for (index, entry) in enumerate(sortedKeysArray) {
    println(index)    // 0   1   2
    println(entry.0)  // a   c   d
    println(entry.1)  // 456 123 45
}

If you want to create an ordered dictionary, you should look into Generics.

You can get numpy version using Terminal or a Python code.

In a Terminal (bash) using Ubuntu:

pip list | grep numpy

In python 3.6.7, this code shows the numpy version:

import numpy
print (numpy.version.version)

If you insert this code in the file shownumpy.py, you can compile it:

python shownumpy.py

or

python3 shownumpy.py

I've got this output:

1.16.1

Here is my implementation, as simple as a ng-show and a request counter.

It use a new service for all request to $http:

myApp.service('RqstSrv', [ '$http', '$rootScope', function($http, $rootScope) {
    var rqstService = {};

    rqstService.call = function(conf) {

        $rootScope.currentCalls = !isNaN($rootScope.currentCalls) ?  $rootScope.currentCalls++ : 0;

        $http(conf).then(function APICallSucceed(response) {
            // Handle success
        }, function APICallError(response) {
            // Handle error
        }).then(function() {
            $rootScope.currentCalls--;
        });
    }
} ]);

And then you can use your loader base on the number of current calls:

<img data-ng-show="currentCalls > 0" src="images/ajax-loader.gif"/>

I encountered the same error when added http-builder to dependencies.
In my case, I could solve by simply excluding asm like this:

compile('org.codehaus.groovy.modules.http-builder:http-builder:0.7'){
    excludes 'xml-apis'
    exclude(group:'xerces', module: 'xercesImpl')
    excludes 'asm'
}

The only thing the eclipse plugin is checking is the tomcat version inside:

catalina.jar!/org/apache/catalina/util/ServerInfo.properties

I replaced the properties file with the one in tomcat7 and that fixed the issue for eclipse

In order to be able to deploy the spring-websockets sample app you need to edit the following file in eclipse:

.settings/org.eclipse.wst.common.project.facet.core.xml

And change the web version to 2.5

<installed facet="jst.web" version="2.5"/>

1. Open xls file with a hex editor.
2. Search for DPB
3. Replace DPB to DPx
4. Save file.
5. Open file in Excel.
6. Click "Yes" if you get any message box.
7. Set new password from VBA Project Properties.
8. Close and open again file, then type your new password to unprotect.

A class that takes a required dependency as a constructor argument can only be instantiated if that argument is provided (you should have a guard clause to make sure the argument is not null.) A constructor therefore enforces the dependency requirement whether or not you're using Spring, making it container-agnostic.

If you use setter injection, the setter may or may not be called, so the instance may never be provided with its dependency. The only way to force the setter to be called is using @Required or @Autowired , which is specific to Spring and is therefore not container-agnostic.

So to keep your code independent of Spring, use constructor arguments for injection.

Update: Spring 4.3 will perform implicit injection in single-constructor scenarios, making your code more independent of Spring by potentially not requiring an @Autowired annotation at all.

I was having the same problem and could not figure out what I was doing wrong. Turns out, the auto-complete for Android Studio was changing the text to either all caps or all lower case (depending on whether I typed in upper case or lower cast words before the auto-complete). The OS was not registering the name due to this issue and I would get the error regarding a missing permission. As stated above, ensure your permissions are labeled correctly:

Correct:

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

Incorrect:

<uses-permission android:name="ANDROID.PERMISSION.ACCESS_FINE_LOCATION" />

Incorrect:

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

Though this may seem trivial, its easy to overlook.

If there is some setting to make permissions non-case-sensitive, please add a comment with the instructions. Thank you!

Purpose of view is displaying model. You should use controller to redirect request before creating model and passing it to view. Use Controller.RedirectToAction method for this.

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

The following command will clear only non-rooted buffers (main, system ..etc).

adb logcat -c

If you want to clear all the buffers (like radio, kernel..etc), Please use the following commands

adb root
adb logcat -b all -c

or

adb root
adb shell logcat -b all -c 

Use the following commands to know the list of buffers that device supports

adb logcat -g
adb logcat -b all -g
adb shell logcat -b all -g

You could have a look at this video about the list view. Its from last years Google IO and still the best walk-through on list views in my mind.

http://www.youtube.com/watch?v=wDBM6wVEO70

1. It inflates layouts (the xml files on your res/layout/ folder) into java Objects such as LinearLayout and other views.

2. Look at the video, will get you up to date with whats the use of the convert view, basically its a recycled view waiting to be reused by you, to avoid creating a new object and slowing down the scrolling of your list.

3. Allows you to reference you list-view from the adapter.

This is the solution we went with. Simply save the scroll position when the overlay is opened, scroll back to the saved position any time the user attempted to scroll the page, and turn the listener off when the overlay is closed.
