git tag -n99

Short and sweet. This will list up to 99 lines from each tag annotation/commit message. Here is a link to the official documentation for git tag.

I now think the limitation of only showing up to 99 lines per tag is actually a good thing as most of the time, if there were really more than 99 lines for a single tag, you wouldn't really want to see all the rest of the lines would you? If you did want to see more than 99 lines per tag, you could always increase this to a larger number.

I mean, I guess there could be a specific situation or reason to want to see massive tag messages, but at what point do you not want to see the whole message? When it has more than 999 lines? 10,000? 1,000,000? My point is, it typically makes sense to have a cap on how many lines you would see, and this number allows you to set that.

Since I am making an argument for what you generally want to see when looking at your tags, it probably makes sense to set something like this as an alias (from Iulian Onofrei's comment below):

git config --global alias.tags 'tag -n99'

I mean, you don't really want to have to type in git tag -n99 every time you just want to see your tags do you? Once that alias is configured, whenever you want to see your tags, you would just type git tags into your terminal. Personally, I prefer to take things a step further than this and create even more abbreviated bash aliases for all my commonly used commands. For that purpose, you could add something like this to your .bashrc file (works on Linux and similar environments):

alias gtag='git tag -n99'

Then whenever you want to see your tags, you just type gtag. Another advantage of going down the alias path (either git aliases or bash aliases or whatever) is you now have a spot already in place where you can add further customizations to how you personally, generally want to have your tags shown to you (like sorting them in certain ways as in my comment below, etc). Once you get over the hurtle of creating your first alias, you will now realize how easy it is to create more of them for other things you like to work in a customized way, like git log, but let's save that one for a different question/answer.

This way to check the condition while pressing 'YES' or 'NO' buttons in MessageBox window.

DialogResult d = MessageBox.Show("Are you sure ?", "Remove Panel", MessageBoxButtons.YesNo);
            if (d == DialogResult.Yes)
            {
                //Contents
            }
            else if (d == DialogResult.No)
            {
                //Contents
            }

<input name="searchbox" onfocus="if (this.value=='search') this.value = ''" onblur="if (this.value=='') this.value = 'search'" type="text" value="search">

Add an onblur event too.

You can also surround the output with str(). I had this same problem because my model had the following (as a simplified example):

def __str__(self):
    return self.pressid

Where pressid was an IntegerField type object. Django (and python in general) expects a string for a str function, so returning an integer causes this error to be thrown.

def __str__(self):
    return str(self.pressid)

That solved the problems I was encountering on the Django management side of the house. Hope it helps with yours.

You're after the zip function.

Taken directly from the question: How to merge lists into a list of tuples in Python?

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

A copy-paste solution for Redis with json serialization:

def get_celery_queue_items(queue_name):
    import base64
    import json  

    # Get a configured instance of a celery app:
    from yourproject.celery import app as celery_app

    with celery_app.pool.acquire(block=True) as conn:
        tasks = conn.default_channel.client.lrange(queue_name, 0, -1)
        decoded_tasks = []

    for task in tasks:
        j = json.loads(task)
        body = json.loads(base64.b64decode(j['body']))
        decoded_tasks.append(body)

    return decoded_tasks

It works with Django. Just don't forget to change yourproject.celery.

I'm using this kind of routine for programmatically chaining animations.

    final Animation anim_out = AnimationUtils.loadAnimation(context, android.R.anim.fade_out); 
    final Animation anim_in  = AnimationUtils.loadAnimation(context, android.R.anim.fade_in); 

    anim_out.setAnimationListener(new AnimationListener()
    {
        @Override
        public void onAnimationStart(Animation animation) {}

        @Override
        public void onAnimationRepeat(Animation animation) {}

        @Override
        public void onAnimationEnd(Animation animation)
        {
            ////////////////////////////////////////
            // HERE YOU CHANGE YOUR IMAGE CONTENT //
            ////////////////////////////////////////
            //ui_image.setImage...

            anim_in.setAnimationListener(new AnimationListener()
            {
                @Override
                public void onAnimationStart(Animation animation) {}

                @Override
                public void onAnimationRepeat(Animation animation) {}

                @Override
                public void onAnimationEnd(Animation animation) {}
            });

            ui_image.startAnimation(anim_in);
        }
    });

    ui_image.startAnimation(anim_out);

I had the same problem, and tried a lot of different variants. After some tries I became able to sudo gem install, but still have problem to install it without sudo.
Finally I found a decission - reinstalling of rvm helped me. Probably it can save time somebody else.

You can also use an oracle defined collection

DECLARE 
  arrayvalues sys.odcivarchar2list;
BEGIN
  arrayvalues := sys.odcivarchar2list('Matt','Joanne','Robert');
  FOR x IN ( SELECT m.column_value m_value
               FROM table(arrayvalues) m )
  LOOP
    dbms_output.put_line (x.m_value||' is a good pal');
  END LOOP;
END;

I would use in-memory array. But with the .COUNT improvement suggested by uziberia:

DECLARE
  TYPE t_people IS TABLE OF varchar2(10) INDEX BY PLS_INTEGER;
  arrayvalues t_people;
BEGIN
  SELECT *
   BULK COLLECT INTO arrayvalues
   FROM (select 'Matt' m_value from dual union all
         select 'Joanne'       from dual union all
         select 'Robert'       from dual
    )
  ;
  --
  FOR i IN 1 .. arrayvalues.COUNT
  LOOP
    dbms_output.put_line(arrayvalues(i)||' is my friend');
  END LOOP;
END;

Another solution would be to use a Hashmap like @Jchomel did here.

NB:

With Oracle 12c you can even query arrays directly now!

This can be achieved using the POSIX clock_gettime function.

In the current version of POSIX, gettimeofday is marked obsolete. This means it may be removed from a future version of the specification. Application writers are encouraged to use the clock_gettime function instead of gettimeofday.

Here is an example of how to use clock_gettime:

#define _POSIX_C_SOURCE 200809L

#include <inttypes.h>
#include <math.h>
#include <stdio.h>
#include <time.h>

void print_current_time_with_ms (void)
{
    long            ms; // Milliseconds
    time_t          s;  // Seconds
    struct timespec spec;

    clock_gettime(CLOCK_REALTIME, &spec);

    s  = spec.tv_sec;
    ms = round(spec.tv_nsec / 1.0e6); // Convert nanoseconds to milliseconds
    if (ms > 999) {
        s++;
        ms = 0;
    }

    printf("Current time: %"PRIdMAX".%03ld seconds since the Epoch\n",
           (intmax_t)s, ms);
}

If your goal is to measure elapsed time, and your system supports the "monotonic clock" option, then you should consider using CLOCK_MONOTONIC instead of CLOCK_REALTIME.

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

An alternative is to use StreamReader.

public void FunctionName(HttpPostedFileBase file)
{
    string result = new StreamReader(file.InputStream).ReadToEnd();
}

A string needs no encoding. It is simply a sequence of Unicode characters.

You need to encode when you want to turn a String into a sequence of bytes. The charset the you choose (UTF-8, cp1255, etc.) determines the Character->Byte mapping. Note that a character is not necessarily translated into a single byte. In most charsets, most Unicode characters are translated to at least two bytes.

Encoding of a String is carried out by:

String s1 = "some text";
byte[] bytes = s1.getBytes("UTF-8"); // Charset to encode into

You need to decode when you have ? sequence of bytes and you want to turn them into a String. When y?u d? that you need to specify, again, the charset with which the byt?s were originally encoded (otherwise you'll end up with garbl?d t?xt).

Decoding:

String s2 = new String(bytes, "UTF-8"); // Charset with which bytes were encoded 

If you want to understand this better, a great text is "The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)"

  SELECT
    sc.name AS ColumnName
   ,ep.*
  FROM
    sys.columns AS sc
    INNER JOIN sys.extended_properties AS ep
      ON ep.major_id = sc.[object_id]
         AND ep.minor_id = sc.column_id
  WHERE

--here put your desired table
    sc.[object_id] = OBJECT_ID('[Northwind].[dbo].[Products]')

-- this is optional, remove this and you get all extended props
    AND ep.name = 'MS_Description'

Here's a different approach without using a regex:

function check_your_datetime($x) {
    return (date('Y-m-d H:i:s', strtotime($x)) == $x);
}

The simplest answer to the meaning of deprecated when used to describe software APIs is:

• Stop using APIs marked as deprecated!
• They will go away in a future release!!
• Start using the new versions ASAP!!!

null = True

Means there is no constraint of database for the field to be filled, so you can have an object with null value for the filled that has this option.

blank = True

Means there is no constraint of validation in django forms. so when you fill a modelForm for this model you can leave field with this option unfilled.

findOne, modify fields & save

User.findOne({username: oldUsername})
  .then(user => {
    user.username = newUser.username;
    user.password = newUser.password;
    user.rights = newUser.rights;

    user.markModified('username');
    user.markModified('password');
    user.markModified('rights');

    user.save(err => console.log(err));
});

OR findOneAndUpdate

User.findOneAndUpdate({username: oldUsername}, {$set: { username: newUser.username, user: newUser.password, user:newUser.rights;}}, {new: true}, (err, doc) => {
    if (err) {
        console.log("Something wrong when updating data!");
    }
    console.log(doc);
});

The code bellow allows the user to un-/check the checkboxes in the DataGridView, if the Cells are created in code

private void gvData_CellClick(object sender, DataGridViewCellEventArgs e)
{
    DataGridViewCheckBoxCell chk = (DataGridViewCheckBoxCell)gvData.Rows[e.RowIndex].Cells[0];

    if (chk.Value == chk.TrueValue)
    {
        gvData.Rows[e.RowIndex].Cells[0].Value = chk.FalseValue;
    }
    else
    {
        gvData.Rows[e.RowIndex].Cells[0].Value = chk.TrueValue;
    }

}

Do it like this: Remember to close iframe tag.

Let's assume you have four cooks. In SOA, you assume they hate each other, so you strive to let them have to talk to each other as little as possible.

How do you do that? Well, you will first define the roles and interface -- cook 1 will make salad, cook 2 will make soup, cook 3 will make the steak, etc.. Then you will place the dishes well organised on the table (so these are the interfaces) and say, "Everybody please place your creation into your assigned dishes. Don't care about anybody else.".

This way, the four cooks have to talk to each other as little as possible, which is very good in software development -- not necessarily because they hate each other, but for other reasons like physical location, efficiency in making decisions etc.

It also means you can recombine the dishes (services) as you like. For example, you might just use the dessert to service a cafe, or just take the soup and combine it with a bread you bought from another company to provide a cheaper menu, or let other restaurants use your salads to combine with their dishes, etc.

One of the most successful implementation of SOA was at Amazon. Because of their design, they could re-package their whole infrastructure and sell it as Amazon Web Service.

*This is only one aspect of SOA.

HTML code

    <form class="form-inline" (ngSubmit)="HelloCorp(modelName)">
        <div class="select">
            <select class="form-control col-lg-8" [(ngModel)]="modelName" required>
                <option *ngFor="let corporation of corporations" [ngValue]="corporation">
                    {{corporation.corp_name}}
                </option>    
            </select>
            <button type="submit" class="btn btn-primary manage">Submit</button>
        </div> 
    </form>

Component code

HelloCorp(corporation) {
    var corporationObj = corporation.value;
}

You will eventually be able to use

background-image: attr(data-image-src url);

but that is not implemented anywhere yet to my knowledge. In the above, url is an optional "type-or-unit" parameter to attr(). See https://drafts.csswg.org/css-values/#attr-notation.

VB sample:

 @Html.ActionLink("Home", "Index", Nothing, New With {.style = "font-weight:bold;", .class = "someClass"})

Sample Css:

.someClass
{
    color: Green !important;
}

In my case, I found that I need the !important attribute to over ride the site.css a:link css class

you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)
cv2.imshow("Window", img)

Let me start with Integrated Security = false

false User ID and Password are specified in the connection string.
true Windows account credentials are used for authentication.

Recognized values are true, false, yes, no, and SSPI.

If User ID and Password are specified and Integrated Security is set to true, then User ID and Password will be ignored and Integrated Security will be used

Quick Solution

tarxz() { tar cf - "$1" | xz -4e > "$1".tar.xz ; }
tarxz name_of_directory

(Notice, not name_of_directory/)

Using xz compression options

If you want to use compression options for xz, or if you are using tar on MacOS, you probably want to avoid the tar -cJf syntax.

According to man xz, the way to do this is:

tar cf - filename | xz -4e > filename.tar.xz

Because I liked Wojciech Adam Koszek's format, but not information:

1. c creates a new archive for the specified files.
2. f reads from a directory (best to put this second because -cf != -fc)
3. - outputs to Standard Output
4. | pipes output to the next command
5. xz -4e calls xz with the -4e compression option. (equal to -4 --extreme)
6. > filename.tar.xz directs the tarred and compressed file to filename.tar.xz

where -4e is, use your own compression options. I often use -k to --keep the original file and -9 for really heavy compression. -z to manually set xz to zip, though it defaults to zipping if not otherwise directed.

To uncompress and untar

To echo Rafael van Horn, to uncompress & untar (see note below):

xz -dc filename.tar.xz | tar x

Note: unlike Rafael's answer, use xz -dc instead of catxz. The docs recommend this in case you are using this for scripting. Best to have a habit of using -d or --decompress instead of unxz as well. However, if you must, using those commands from the command line is fine.

FirstOrDefault returns the default value of a type if no item matches the predicate. For reference types that is null. Thats the reason for the exception.

So you just have to check for null first:

string displayName = null;
var keyValue = Dictionary
    .FirstOrDefault(x => x.Value.ID == long.Parse(options.ID));
if(keyValue  != null)
{
    displayName = keyValue.Value.DisplayName;
} 

But what is the key of the dictionary if you are searching in the values? A Dictionary<tKey,TValue> is used to find a value by the key. Maybe you should refactor it.

Another option is to provide a default value with DefaultIfEmpty:

string displayName = Dictionary
    .Where(kv => kv.Value.ID == long.Parse(options.ID))
    .Select(kv => kv.Value.DisplayName)   // not a problem even if no item matches
    .DefaultIfEmpty("--Option unknown--") // or no argument -> null
    .First();                             // cannot cause an exception

If your column is of type DATE (as you say), then you don't need to convert it into a string first (in fact you would convert it implicitly to a string first, then explicitly to a date and again explicitly to a string):

SELECT TO_CHAR(COL1, 'mm/dd/yyyy') FROM TABLE1

The date format your seeing for your column is an artifact of the tool your using (TOAD, SQL Developer etc.) and it's language settings.

For those who searches for an answer without parsing and loosing milliseconds, given dt_obj is a datetime:

python3 only, elegant

int(dt_obj.timestamp() * 1000)

both python2 and python3 compatible:

import time

int(time.mktime(dt_obj.utctimetuple()) * 1000 + dt_obj.microsecond / 1000)

Windows filenames are pretty unrestrictive, so really it might not even be that much of an issue. The characters that are disallowed by Windows are:

\ / : * ? " < > |

You could easily write an expression to check if those characters are present. A better solution though would be to try and name the files as the user wants, and alert them when a filename doesn't stick.

Initialy both dropdown have same option ,the option you select in firstdropdown is hidden in seconddropdown."value" is custom attribute which is unique.

$(".seconddropdown option" ).each(function() {
    if(($(this).attr('value')==$(".firstdropdown  option:selected").attr('value') )){
        $(this).hide();
        $(this).siblings().show();
    }
});

this way is a bit more flexible than using all():

my_list = [[1, 2, 0], [1, 2, 0], [1, 2, 0]]
all_zeros = False if False in [x[2] == 0 for x in my_list] else True
any_zeros = True if True in [x[2] == 0 for x in my_list] else False

or more succinctly:

all_zeros = not False in [x[2] == 0 for x in my_list]
any_zeros = 0 in [x[2] for x in my_list]

3 steps:

1. Check the sorce code (HTML) of YouTube, you'll get the link like this (http%253A%252F%252Fo-o.preferred.telemar-cnf1.v18.lscache6.c.youtube.com%252Fvideoplayback ...);

2. Decode the url (remove the codes %2B,%25 etc), create a decoder with the codes: http://www.w3schools.com/tags/ref_urlencode.asp and use the function Uri.decode(url) to replace invalid escaped octets;

3. Use the code to download stream:

   URL u = null;
   InputStream is = null;  
   
   try {
       u = new URL(url);
       is = u.openStream(); 
       HttpURLConnection huc = (HttpURLConnection)u.openConnection(); //to know the size of video
       int size = huc.getContentLength();                 
   
       if(huc != null) {
           String fileName = "FILE.mp4";
           String storagePath = Environment.getExternalStorageDirectory().toString();
           File f = new File(storagePath,fileName);
   
           FileOutputStream fos = new FileOutputStream(f);
           byte[] buffer = new byte[1024];
           int len1 = 0;
           if(is != null) {
               while ((len1 = is.read(buffer)) > 0) {
                   fos.write(buffer,0, len1);  
               }
           }
           if(fos != null) {
               fos.close();
           }
       }                       
   } catch (MalformedURLException mue) {
       mue.printStackTrace();
   } catch (IOException ioe) {
       ioe.printStackTrace();
   } finally {
       try {               
           if(is != null) {
               is.close();
           }
       } catch (IOException ioe) {
           // just going to ignore this one
       }
   }
   

That's all, most of stuff you'll find on the web!!!

The new version of SharePoint and Office (SharePoint 2010 and Office 2010) respectively are supposed to allow for this. This also includes the web based versions. I have seen Word and Excel in action do this, not sure about other client applications.

I am not sure about the specific implementation features you are asking about in terms of security though. Sorry.,=

Here is a discussion

http://blogs.msdn.com/b/sharepoint/archive/2009/10/19/sharepoint-2010.aspx

var anchor = angular.element('<a/>');
anchor.css({display: 'none'}); // Make sure it's not visible
angular.element(document.body).append(anchor); // Attach to document

anchor.attr({
    href: 'data:attachment/csv;charset=utf-8,' + encodeURI(data),
    target: '_blank',
    download: 'filename.csv'
})[0].click();

anchor.remove(); // Clean it up afterwards

This code works both Mozilla and chrome

In case you update the image multiple times and it gets CACHED and does not update, add a random string at the end:

// update image in dom
$('#target').attr('src', 'https://example.com/img.jpg?rand=' + Math.random());

Using jQuery UI in combination with the excellent datetimepicker plugin from http://trentrichardson.com/examples/timepicker/

You can specify the dateFormat and timeFormat

$('#datepicker').datetimepicker({
    dateFormat: "yy-mm-dd",
    timeFormat:  "hh:mm:ss"
});

Setting the underlying socket ReceiveTimeout property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout. You can read the docs for more information.

Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.

I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  var bytes = 0;
  client.Client.ReceiveTimeout = 20;
  do
  {
      try
      {
          bytes = stm.Read(resp, 0, resp.Length);
          memStream.Write(resp, 0, bytes);
      }
      catch (IOException ex)
      {
          // if the ReceiveTimeout is reached an IOException will be raised...
          // with an InnerException of type SocketException and ErrorCode 10060
          var socketExept = ex.InnerException as SocketException;
          if (socketExept == null || socketExept.ErrorCode != 10060)
              // if it's not the "expected" exception, let's not hide the error
              throw ex;

A summary.lm object stores these values in a matrix called 'coefficients'. So the value you are after can be accessed with:

a2Pval <- summary(mg)$coefficients[2, 4]

Or, more generally/readably, coef(summary(mg))["a2","Pr(>|t|)"]. See here for why this method is preferred.

To center it, you can use the technique shown here: Absolute centering.

To make it as big as possible, give it max-width and max-height of 100%.

To maintain the aspect ratio (even when the width is specifically set like in the snippet below), use object-fit as explained here.

.className {
    max-width: 100%;
    max-height: 100%;
    bottom: 0;
    left: 0;
    margin: auto;
    overflow: auto;
    position: fixed;
    right: 0;
    top: 0;
    -o-object-fit: contain;
    object-fit: contain;
}

<img src="https://i.imgur.com/HmezgW6.png" class="className" />

<!-- Slider to control the image width, only to make demo clearer !-->
<input type="range" min="10" max="2000" value="276" step="10" oninput="document.querySelector('img').style.width = (this.value +'px')" style="width: 90%; position: absolute; z-index: 2;" >

The docs give a pretty good explanation of the difference between apply() and commit():

Unlike commit(), which writes its preferences out to persistent storage synchronously, apply() commits its changes to the in-memory SharedPreferences immediately but starts an asynchronous commit to disk and you won't be notified of any failures. If another editor on this SharedPreferences does a regular commit() while a apply() is still outstanding, the commit() will block until all async commits are completed as well as the commit itself. As SharedPreferences instances are singletons within a process, it's safe to replace any instance of commit() with apply() if you were already ignoring the return value.

I wanted send some strings to backend server. I didnt use json with multipart, I have used request params.

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public void uploadFile(HttpServletRequest request,
        HttpServletResponse response, @RequestParam("uuid") String uuid,
        @RequestParam("type") DocType type,
        @RequestParam("file") MultipartFile uploadfile)

Url would look like

http://localhost:8080/file/upload?uuid=46f073d0&type=PASSPORT

I am passing two params (uuid and type) along with file upload. Hope this will help who don't have the complex json data to send.

Use the jQuery ajaxSetup function, that can set up default values for all ajax requests.

$.ajaxSetup({
  headers: {
    'Authorization': "Basic XXXXX"
  }
});

I've found the following "cheat" to work very neatly and error-free

> dimnames <- list(time=c(0, 0.5, 1), name=c("C_0", "C_1"))
> mat <- matrix(data, ncol=2, nrow=3, dimnames=dimnames)
> head(mat, 2) #this returns the number of rows indicated in a data frame format
> df <- data.frame(head(mat, 2)) #"data.frame" might not be necessary

Et voila!

I had similar problem with Yarn, none of above worked for me, so I simply removed ./node_modules and run yarn install and problem gone.

Pure JavaScript ES6 solution

• Catch every option with a querySelectorAll function and split the values string.
• Use Array#forEach to iterate over every element from the values array.
• Use Array#find to find the option matching given value.
• Set it's selected attribute to true.

Note: Array#from transforms an array-like object into an array and then you are able to use Array.prototype functions on it, like find or map.

var values = "Test,Prof,Off",_x000D_
    options = Array.from(document.querySelectorAll('#strings option'));_x000D_
_x000D_
values.split(',').forEach(function(v) {_x000D_
  options.find(c => c.value == v).selected = true;_x000D_
});

<select name='strings' id="strings" multiple style="width:100px;">_x000D_
    <option value="Test">Test</option>_x000D_
    <option value="Prof">Prof</option>_x000D_
    <option value="Live">Live</option>_x000D_
    <option value="Off">Off</option>_x000D_
    <option value="On">On</option>_x000D_
</select>

You can also use:

Range( RangeName ).end(xlDown).row

to find the last row with data in it starting at your named range.

With Xcode-8.1 & iOS-10.1

1. Add your Apple ID in Xcode Preferences > Accounts > Add Apple ID:

2. Enable signing to Automatically && Select Team that you have created before:

3. Change the Bundle Identifier:

4. Code Signing to iOS Developer:

5. Provision profile to Automatic:

You can now run your project on a device!

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

Surprisingly nobody have mentioned all powerful SUDO. Had the same problem and sudo fixed it

I would suggest to pass the JSON data in the body as a POST request.But if you still want to pass this as a parameter in URL,you will have to encode your URL like below just for example:-

for ex json is :->{"name":"ABC","id":"1"}

testurl:80/service?data=%7B%22name%22%3A%22ABC%22%2C%22id%22%3A%221%22%7D

for more information on URL encoding refer below

https://en.wikipedia.org/wiki/Percent-encoding

Use an interval to check

You can setup an interval to keep checking if the user has scrolled then do something accordingly.

Borrowing from the great John Resig in his article.

Example:

    let didScroll = false;

    window.onscroll = () => didScroll = true;

    setInterval(() => {
        if ( didScroll ) {
            didScroll = false;
            console.log('Someone scrolled me!')
        }
    }, 250);

See live example

It's simple actually you don't need any plugins, just jquery or you can do it with simple javascript.

$('#dialog').on('click', function(e){
  e.stopPropagation();
});
$(document.body).on('click', function(e){
  master.hide();
});

yeah it works for me as well.

Note : we need to use window.parent.document

    $("button", window.parent.document).click(function()
    {
        alert("Functionality defined by def");
    });

You have three possibilities to do this, but it's not trivial. The main idea of all IDEs is that all of them are the parents of the child (debug) processes. In this case, it is possible to manipulate with standard input, output and error handler. So IDEs start child applications and redirect out into the internal output window. I know about one more possibility, but it will come in future

1. You could implement your own debug engine for Visual Studio. Debug Engine control starting and debugging for application. Examples for this you could find how to do this on docs.microsoft.com (Visual Studio Debug engine)
2. Redirect form application using duplication of std handler for c++ or use Console.SetOut(TextWriter) for c#. If you need to print into the output window you need to use Visual Studio extension SDK. Example of the second variant you could find on Github.
3. Start application that uses System.Diagnostics.Debug.WriteLine (for printing into output) and than it will start child application. On starting a child, you need to redirect stdout into parent with pipes. You could find an example on MSDN. But I think this is not the best way.

1) When the user logs out (Forms signout in Action) I want to redirect to a login page.

public ActionResult Logout() {
    //log out the user
    return RedirectToAction("Login");
}

2) In a Controller or base Controller event eg Initialze, I want to redirect to another page (AbsoluteRootUrl + Controller + Action)

Why would you want to redirect from a controller init?

the routing engine automatically handles requests that come in, if you mean you want to redirect from the index action on a controller simply do:

public ActionResult Index() {
    return RedirectToAction("whateverAction", "whateverController");
}

Just use two Listboxes, one for header and other for data

1. for headers - set RowSource property to top row e.g. Incidents!Q4:S4

2. for data - set Row Source Property to Incidents!Q5:S10

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:

In [16]: import numpy as np

In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()

TypeError: 'numpy.ndarray' object is not callable

If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean or pd.rolling_std to a numpy array earlier in your code.

What I mean is something like this:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan,  nan,  nan])

In [4]: pd.rolling_mean = np.array([1,2,3])

In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...

TypeError: 'numpy.ndarray' object is not callable

So, basically you need to search the rest of your codebase for pd.rolling_mean = ... and/or pd.rolling_std = ... to see where you may have overwritten them.

I believe that phrase should have been worded as follows:

bcrypt has salts built into the generated hashes to prevent rainbow table attacks.

The bcrypt utility itself does not appear to maintain a list of salts. Rather, salts are generated randomly and appended to the output of the function so that they are remembered later on (according to the Java implementation of bcrypt). Put another way, the "hash" generated by bcrypt is not just the hash. Rather, it is the hash and the salt concatenated.

When you add a "static" keyword to a method, it means that underlying implementation gives the same result for any instance of the class. Needless to say, result varies with change in the value of parameters

In C++11, you can use std::to_string, e.g.:

auto result = name + std::to_string( age );

Use all the jackson dependencies(databind,core, annotations, scala(if you are using spark and scala)) with the same version.. and upgrade the versions to the latest releases..

Note: Use Scala dependency only if you are working with scala. Otherwise it is not needed.

Python lists are heterogeneous that is the elements in the same list can be any type of object. The expression: c.append(c) appends the object c what ever it may be to the list. In the case it makes the list itself a member of the list.

The expression c += c adds two lists together and assigns the result to the variable c. The overloaded + operator is defined on lists to create a new list whose contents are the elements in the first list and the elements in the second list.

So these are really just different expressions used to do different things by design.

Starting with Bootstrap v3.3.0 you can use .media-left and .media-body

<div class="media">
    <span class="media-left">
        <img src="../site/img/success32.png" alt="...">
    </span>
    <div class="media-body">
        <h3 class="media-heading">Experience</h3>
        ...
    </div>
</div>

Documentation: https://getbootstrap.com/docs/3.3/components/#media

Maybe a little late, but I found an easier way to set the defaults! You have to right-click on the right of your tab and choose "size", then click on your window, and it should keep it as the default size.

Same answer in Kotlin

inner class MyViewHolder(v: View, myOnClickListener: MyOnClickListener) : RecyclerView.ViewHolder(v) {
    init {
        v.setOnClickListener { v -> myOnClickListener.onClick(v, adapterPosition) }
    }
}

override fun onCreateViewHolder(viewGroup: ViewGroup, viewType: Int): MyViewHolder {
    val view = LayoutInflater.from(viewGroup.context).inflate(R.layout.myview, viewGroup, false)
    return MyViewHolder(view, mOnClickListener)
}

inner class MyOnClickListener {
    fun onClick(view: View, position: Int) {
        val item = mList[position]
        Toast.makeText(view.context, item, Toast.LENGTH_LONG).show()
    }
}

canvas.toDataURL() will provide you a data url which can be used as source:

var image = new Image();
image.id = "pic";
image.src = canvas.toDataURL();
document.getElementById('image_for_crop').appendChild(image);

Complete example

Here's a complete example with some random lines. The black-bordered image is generated on a <canvas>, whereas the blue-bordered image is a copy in a <img>, filled with the <canvas>'s data url.

// This is just image generation, skip to DATAURL: below
var canvas = document.getElementById("canvas")
var ctx = canvas.getContext("2d");

// Just some example drawings
var gradient = ctx.createLinearGradient(0, 0, 200, 100);
gradient.addColorStop("0", "#ff0000");
gradient.addColorStop("0.5" ,"#00a0ff");
gradient.addColorStop("1.0", "#f0bf00");

ctx.beginPath();
ctx.moveTo(0, 0);
for (let i = 0; i < 30; ++i) {
  ctx.lineTo(Math.random() * 200, Math.random() * 100);
}
ctx.strokeStyle = gradient;
ctx.stroke();

// DATAURL: Actual image generation via data url
var target = new Image();
target.src = canvas.toDataURL();

document.getElementById('result').appendChild(target);

canvas { border: 1px solid black; }
img    { border: 1px solid blue;  }
body   { display: flex; }
div + div {margin-left: 1ex; }

<div>
  <p>Original:</p>
  <canvas id="canvas" width=200 height=100></canvas>
</div>
<div id="result">
  <p>Result via &lt;img&gt;:</p>
</div>

Take a look at this site: http://www.json.org/

Also, you can try calling JSON.stringify() on one of your objects from the browser to see the json format. You'd have to do this in the console or a test page.

You could do the following:

pg_dump -h <host ip address> -U <host db user name> -t <host table> > <host database> | psql -h localhost -d <local database> -U <local db user>

As The Tin Man suggests (above) RVM (Ruby Version Manager) is the Standard for upgrading your Ruby installation on OSX: https://rvm.io

To get started, open a Terminal Window and issue the following command:

\curl -L https://get.rvm.io | bash -s stable --ruby

( you will need to trust the RVM Dev Team that the command is not malicious - if you're a paranoid penguin like me, you can always go read the source: https://github.com/wayneeseguin/rvm ) When it's complete you need to restart the terminal to get the rvm command working.

rvm list known

( shows you the latest available versions of Ruby )

rvm install ruby-2.3.1

For a specific version, followed by

rvm use ruby-2.3.1

or if you just want the latest (current) version:

rvm install current && rvm use current

( installs the current stable release - at time of writing ruby-2.3.1 - please update this wiki when new versions released )

Note on Compiling Ruby: In my case I also had to install Homebrew http://mxcl.github.com/homebrew/ to get the gems I needed (RSpec) which in turn forces you to install Xcode (if you haven't already) https://itunes.apple.com/us/app/xcode/id497799835 AND/OR install the GCC package from: https://github.com/kennethreitz/osx-gcc-installer to avoid errors running "make".

Edit: As of Mavericks you can choose to install only the Xcode command line tools instead of the whole Xcode package, which comes with gcc and lots of other things you might need for building packages. It can be installed by running xcode-select --install and following the on-screen prompt.

• Examples: https://rvm.io/workflow/examples/
• Screencast: http://screencasts.org/episodes/how-to-use-rvm

Note on erros: if you get the error "RVM is not a function" while trying this command, visit: How do I change my Ruby version using RVM? for the solution.

Here is (low and dirty) workaround in case you need to use ajax or some feature which you cannot use when making link manually (using tag):

<%= Html.ActionLink("LinkTextToken", "ActionName", "ControllerName").ToHtmlString().Replace("LinkTextToken", "Refresh <span class='large sprite refresh'></span>")%>

You can use any text instead of 'LinkTextToken', it is there only to be replaced, it is only important that it does not occur anywhere else inside actionlink.

I got same issue while working with Modal Popup Bootstrap , I used Id and trigger click event for showing and hidding modal popup instead of $("#Id").modal('show') and $("#id").modal('hide'), `

    <button type="button" id="btnPurchaseClose" class="close" data dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span></button>
<a class="btn btn-default" id="btnOpenPurchasePopup" data-toggle="modal" data target="#newPurchasePopup">Select</a>
    $('#btnPurchaseClose').trigger('click');// for close popup

     $('#btnOpenPurchase').trigger('click');`// for open popup

When you export your project as a 'Runnable jar' (Right mouse on project -> Export -> Runnable jar) you have the option to package all dependencies into the generated jar. It also has two other ways (see screenshot) to export your libraries, be aware of the licences when deciding which packaging method you will use.

The 'launch configuration' dropdown is populated with classes containing a main(String[]) method. The selected class is started when you 'run' the jar.

Exporting as a runnable jar uses the dependencies on your build path (Right mouse on project -> Build Path -> Configure Build Path...). When you export as a 'regular' (non-runnable) jar you can select any file in your project(s). If you have the libraries in your project folder you can include them but external dependencies, for example maven, cannot be included (for maven projects, search here).

I created a DefaultableDictionary to do exactly what you are asking for!

using System;
using System.Collections;
using System.Collections.Generic;
using System.Collections.ObjectModel;

namespace DefaultableDictionary {
    public class DefaultableDictionary<TKey, TValue> : IDictionary<TKey, TValue> {
        private readonly IDictionary<TKey, TValue> dictionary;
        private readonly TValue defaultValue;

        public DefaultableDictionary(IDictionary<TKey, TValue> dictionary, TValue defaultValue) {
            this.dictionary = dictionary;
            this.defaultValue = defaultValue;
        }

        public IEnumerator<KeyValuePair<TKey, TValue>> GetEnumerator() {
            return dictionary.GetEnumerator();
        }

        IEnumerator IEnumerable.GetEnumerator() {
            return GetEnumerator();
        }

        public void Add(KeyValuePair<TKey, TValue> item) {
            dictionary.Add(item);
        }

        public void Clear() {
            dictionary.Clear();
        }

        public bool Contains(KeyValuePair<TKey, TValue> item) {
            return dictionary.Contains(item);
        }

        public void CopyTo(KeyValuePair<TKey, TValue>[] array, int arrayIndex) {
            dictionary.CopyTo(array, arrayIndex);
        }

        public bool Remove(KeyValuePair<TKey, TValue> item) {
            return dictionary.Remove(item);
        }

        public int Count {
            get { return dictionary.Count; }
        }

        public bool IsReadOnly {
            get { return dictionary.IsReadOnly; }
        }

        public bool ContainsKey(TKey key) {
            return dictionary.ContainsKey(key);
        }

        public void Add(TKey key, TValue value) {
            dictionary.Add(key, value);
        }

        public bool Remove(TKey key) {
            return dictionary.Remove(key);
        }

        public bool TryGetValue(TKey key, out TValue value) {
            if (!dictionary.TryGetValue(key, out value)) {
                value = defaultValue;
            }

            return true;
        }

        public TValue this[TKey key] {
            get
            {
                try
                {
                    return dictionary[key];
                } catch (KeyNotFoundException) {
                    return defaultValue;
                }
            }

            set { dictionary[key] = value; }
        }

        public ICollection<TKey> Keys {
            get { return dictionary.Keys; }
        }

        public ICollection<TValue> Values {
            get
            {
                var values = new List<TValue>(dictionary.Values) {
                    defaultValue
                };
                return values;
            }
        }
    }

    public static class DefaultableDictionaryExtensions {
        public static IDictionary<TKey, TValue> WithDefaultValue<TValue, TKey>(this IDictionary<TKey, TValue> dictionary, TValue defaultValue ) {
            return new DefaultableDictionary<TKey, TValue>(dictionary, defaultValue);
        }
    }
}

This project is a simple decorator for an IDictionary object and an extension method to make it easy to use.

The DefaultableDictionary will allow for creating a wrapper around a dictionary that provides a default value when trying to access a key that does not exist or enumerating through all the values in an IDictionary.

Example: var dictionary = new Dictionary<string, int>().WithDefaultValue(5);

Blog post on the usage as well.

If you want SSMS to maintain a query history, use the SSMS Tool Pack add on.

If you want to monitor the SQL Server for currently running queries, use SQL PRofiler as other have already suggested.

Just implemented my OWIN Service with Bearer (called access_token in the following) and Refresh Tokens. My insight into this is that you can use different flows. So it depends on the flow you want to use how you set your access_token and refresh_token expiration times.

I will describe two flows A and B in the follwing (I suggest what you want to have is flow B):

A) expiration time of access_token and refresh_token are the same as it is per default 1200 seconds or 20 minutes. This flow needs your client first to send client_id and client_secret with login data to get an access_token, refresh_token and expiration_time. With the refresh_token it is now possible to get a new access_token for 20 minutes (or whatever you set the AccessTokenExpireTimeSpan in the OAuthAuthorizationServerOptions to). For the reason that the expiration time of access_token and refresh_token are the same, your client is responsible to get a new access_token before the expiration time! E.g. your client could send a refresh POST call to your token endpoint with the body (remark: you should use https in production)

grant_type=refresh_token&client_id=xxxxxx&refresh_token=xxxxxxxx-xxxx-xxxx-xxxx-xxxxx

to get a new token after e.g. 19 minutes to prevent the tokens from expiration.

B) in this flow you want to have a short term expiration for your access_token and a long term expiration for your refresh_token. Lets assume for test purpose you set the access_token to expire in 10 seconds (AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(10)) and the refresh_token to 5 Minutes. Now it comes to the interesting part setting the expiration time of refresh_token: You do this in your createAsync function in SimpleRefreshTokenProvider class like this:

var guid = Guid.NewGuid().ToString();


        //copy properties and set the desired lifetime of refresh token
        var refreshTokenProperties = new AuthenticationProperties(context.Ticket.Properties.Dictionary)
        {
            IssuedUtc = context.Ticket.Properties.IssuedUtc,
            ExpiresUtc = DateTime.UtcNow.AddMinutes(5) //SET DATETIME to 5 Minutes
            //ExpiresUtc = DateTime.UtcNow.AddMonths(3) 
        };
        /*CREATE A NEW TICKET WITH EXPIRATION TIME OF 5 MINUTES 
         *INCLUDING THE VALUES OF THE CONTEXT TICKET: SO ALL WE 
         *DO HERE IS TO ADD THE PROPERTIES IssuedUtc and 
         *ExpiredUtc to the TICKET*/
        var refreshTokenTicket = new AuthenticationTicket(context.Ticket.Identity, refreshTokenProperties);

        //saving the new refreshTokenTicket to a local var of Type ConcurrentDictionary<string,AuthenticationTicket>
        // consider storing only the hash of the handle
        RefreshTokens.TryAdd(guid, refreshTokenTicket);            
        context.SetToken(guid);

Now your client is able to send a POST call with a refresh_token to your token endpoint when the access_token is expired. The body part of the call may look like this: grant_type=refresh_token&client_id=xxxxxx&refresh_token=xxxxxxxx-xxxx-xxxx-xxxx-xx

One important thing is that you may want to use this code not only in your CreateAsync function but also in your Create function. So you should consider to use your own function (e.g. called CreateTokenInternal) for the above code. Here you can find implementations of different flows including refresh_token flow(but without setting the expiration time of the refresh_token)

Here is one sample implementation of IAuthenticationTokenProvider on github (with setting the expiration time of the refresh_token)

I am sorry that I can't help out with further materials than the OAuth Specs and the Microsoft API Documentation. I would post the links here but my reputation doesn't let me post more than 2 links....

I hope this may help some others to spare time when trying to implement OAuth2.0 with refresh_token expiration time different to access_token expiration time. I couldn't find an example implementation on the web (except the one of thinktecture linked above) and it took me some hours of investigation until it worked for me.

New info: In my case I have two different possibilities to receive tokens. One is to receive a valid access_token. There I have to send a POST call with a String body in format application/x-www-form-urlencoded with the following data

client_id=YOURCLIENTID&grant_type=password&username=YOURUSERNAME&password=YOURPASSWORD

Second is if access_token is not valid anymore we can try the refresh_token by sending a POST call with a String body in format application/x-www-form-urlencoded with the following data grant_type=refresh_token&client_id=YOURCLIENTID&refresh_token=YOURREFRESHTOKENGUID

I had the a similar problem and want to share my solution here.

I have the following HTML:

<div data-my-directive>
  <div id='sub' ng-include='includedFile.htm'></div>
</div>

Problem: In the link-function of directive of the parent div I wanted to jquery'ing the child div#sub. But it just gave me an empty object because ng-include hadn't finished when link function of directive ran. So first I made a dirty workaround with $timeout, which worked but the delay-parameter depended on client speed (nobody likes that).

Works but dirty:

app.directive('myDirective', [function () {
    var directive = {};
    directive.link = function (scope, element, attrs) {
        $timeout(function() {
            //very dirty cause of client-depending varying delay time 
            $('#sub').css(/*whatever*/);
        }, 350);
    };
    return directive;
}]);

Here's the clean solution:

app.directive('myDirective', [function () {
    var directive = {};
    directive.link = function (scope, element, attrs) {
        scope.$on('$includeContentLoaded', function() {
            //just happens in the moment when ng-included finished
            $('#sub').css(/*whatever*/);
        };
    };
    return directive;
}]);

Maybe it helps somebody.

There are four main alternatives. Both have their quirks, but Method 4 has many advantages from my view.

./script is a shell script starting by #!/usr/bin/php

Method 1: $argv

./script hello wo8844rld
// $argv[0] = "script", $argv[1] = "hello", $argv[2] = "wo8844rld"

?? Using $argv, the parameter order is critical.

Method 2: getopt()

./script -p7 -e3
// getopt("p::")["p"] = "7", getopt("e::")["e"] = "3"

It's hard to use in conjunction of $argv, because:

?? The parsing of options will end at the first non-option found, anything that follows is discarded.

?? Only 26 parameters as the alphabet.

Method 3: Bash Global variable

P9="xptdr" ./script
// getenv("P9") = "xptdr"
// $_SERVER["P9"] = "xptdr"

Those variables can be used by other programs running in the same shell.

They are blown when the shell is closed, but not when the PHP program is terminated. We can set them permanent in file ~/.bashrc!

Method 4: STDIN pipe and stream_get_contents()

Some piping examples:

Feed a string:

./script <<< "hello wo8844rld"
// stream_get_contents(STDIN) = "hello wo8844rld"

Feed a string using bash echo:

echo "hello wo8844rld" | ./script
// explode(" ",stream_get_contents(STDIN)) ...

Feed a file content:

./script < ~/folder/Special_params.txt
// explode("\n",stream_get_contents(STDIN)) ...

Feed an array of values:

./script <<< '["array entry","lol"]'
// var_dump( json_decode(trim(stream_get_contents(STDIN))) );

Feed JSON content from a file:

echo params.json | ./script
// json_decode(stream_get_contents(STDIN)) ...

It might work similarly to fread() or fgets(), by reading the STDIN.

Bash-Scripting Guide

Reload the current document:

 <script type="text/javascript">
 function reloadPage()
 {
   window.location.reload()
 }
 </script>

The rem command is indeed for comments. It doesn't inherently update anyone after running the script. Some script authors might use it that way instead of echo, though, because by default the batch interpreter will print out each command before it's processed. Since rem commands don't do anything, it's safe to print them without side effects. To avoid printing a command, prefix it with @, or, to apply that setting throughout the program, run @echo off. (It's echo off to avoid printing further commands; the @ is to avoid printing that command prior to the echo setting taking effect.)

So, in your batch file, you might use this:

@echo off
REM To skip the following Python commands, put "REM" before them:
python foo.py
python bar.py

Yes, your secret key appears to be missing. Without it, you will not be able to decrypt the files.

Do you have the key backed up somewhere?

Re-creating the keys, whether you use the same passphrase or not, will not work. Each key pair is unique.

When a search engine spider finds 301 status code in the response header of a webpage, it understands that this webpage no longer exists, it searches for location header in response pick the new URL and replace the indexed URL with the new one and also transfer pagerank.

So search engine refreshes all indexed URL that no longer exist (301 found) with the new URL, this will retain your old webpage traffic, pagerank and divert it to the new one (you will not lose you traffic of old webpage).

Browser: if a browser finds 301 status code then it caches the mapping of the old URL with the new URL, the client/browser will not attempt to request the original location but use the new location from now on unless the cache is cleared.

When a search engine spider finds 302 status for a webpage, it will only redirect temporarily to the new location and crawl both of the pages. The old webpage URL still exists in the search engine database and it always attempts to request the old location and crawl it. The client/browser will still attempt to request the original location.

Read more about how to implement it in asp.net c# and what is the impact on search engines - http://www.dotnetbull.com/2013/08/301-permanent-vs-302-temporary-status-code-aspnet-csharp-Implementation.html

Generally i go with views to make life easier, get extended details from some entity that's stored over multiple tables (eliminate lots of joins in code to enhance readability) and sometimes to share data over multiple databases or even to make inserts easier to read.

You can use

insert into <table_name> select <fieldlist> from <tables>

for x in range(9):
    exec("string" + str(x) + " = 'hello'")

This should work.

$protocal = 'http';
if ($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https' || $_SERVER['HTTPS'] == 'on') {$protocal = 'https';}


echo $protocal;

If you presenting a controller without a Navigation Controller, you can call the following code from a method of the presented controller.

self.presentingViewController?.dismiss(animated: true, completion: nil)

If your ViewController is presented modally, optional presentingViewController will be not nil and the code will be executed.

As I was researching this I found my answer, but can't find the answer on the internet, so I thought I'd share this:

I fixed my issue by modifying my applicationhost.config file. My file was saved in the "\My Documents\IISExpress\config" folder.

It seems that VS2013 was ignoring my web.config file and applying different authentication methods.

I had to modify this portion of the file to look like the below. In truth, I only modified the anonymousAuthentication to be false and the windowsAuthentication mode to true.

<authentication>

  <anonymousAuthentication enabled="false" userName="" />

  <basicAuthentication enabled="false" />

  <clientCertificateMappingAuthentication enabled="false" />

  <digestAuthentication enabled="false" />

  <iisClientCertificateMappingAuthentication enabled="false">
  </iisClientCertificateMappingAuthentication>

  <windowsAuthentication enabled="true">
    <providers>
      <add value="Negotiate" />
      <add value="NTLM" />
    </providers>
  </windowsAuthentication>

</authentication>

In my case, along with Mekanik's suggestions, I was receiving this error in Windows Server 2012 and I had to tick "HTTP Activation" in "Add Role Services".

A perfect 1/3 cannot exist in CSS with full cross browser support (anything below IE9). I personally would do: (It's not the perfect solution, but it's about as good as you'll get for all browsers)

#c1, #c2 {
    width: 33%;
}

#c3 {
    width: auto;
}

you can use:

define("PATH_ROOT", dirname(__FILE__));
include_once PATH_ROOT . "/PoliticalForum/headerSite.php";

You could use the Byte conversion methods from Google Guava.

Example:

byte[] bytes = Longs.toByteArray(12345L);

BT version 2.0 or less - You should be able to pair/bond using a standard PIN code, entered programmatically e.g. 1234 or 0000. This is not very secure but many BT devices do this.

BT version 2.1 or greater - Mode 4 Secure Simple Pairing "just works" model can be used. It uses elliptical encryption (whatever that is) and is very secure but is open to Man In The Middle attacks. Compared to the old '0000' pin code approach it is light years ahead. This doesn't require any user input.

This is according to the Bluetooth specs but what you can use depends on what verson of the Bluetooth standard your stack supports and what API you have.

You can use reorder:

qplot(reorder(factor(cyl),factor(cyl),length),data=mtcars,geom="bar")

Edit:

To have the tallest bar at the left, you have to use a bit of a kludge:

qplot(reorder(factor(cyl),factor(cyl),function(x) length(x)*-1),
   data=mtcars,geom="bar")

I would expect this to also have negative heights, but it doesn't, so it works!

for 50% element

width: 50%;
display: block;
float: right;
margin-right: 25%;

The main reason is that deflate is faster to encode than gzip and on a busy server that might make a difference. With static pages it's a different question, since they can easily be pre-compressed once.

Create a file with .gitignore & put the folder or file name which one you want to ignore.

to ignore everything below node_modules folder

echo node_modules/ > .gitignore 

You either have to make the method Shared or use an instance of the class General:

Dim gen = New General()
gen.updateDynamics(get_prospect.dynamicsID)

or

General.updateDynamics(get_prospect.dynamicsID)

Public Shared Sub updateDynamics(dynID As Int32)
    ' ... '
End Sub

Shared(VB.NET)

Overide the dismiss() method like this:

@Override
public void dismiss() {
    Window window = getWindow();
    if (window == null) {
        return;
    }
    View decor = window.getDecorView();
    if (decor != null && decor.getParent() != null) {
        super.dismiss();
    }
}

To reproduce the issue, just finish activity before dismiss dialog.

You can't follow the cursor with a DIV, but you can draw a DIV when moving the cursor!

$(document).on('mousemove', function(e){
    $('#your_div_id').css({
       left:  e.pageX,
       top:   e.pageY
    });
});

That div must be off the float, so position: absolute should be set.

Native method:

for example if you have table

Users(Id, name)

You can do this:

select 'insert into Table values(Id=' + Id + ', name=' + name + ')' from Users

I got a more detailed exception when I added it programmatically - AddServiceEndpoint:

string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));  

host.AddServiceEndpoint(typeof(MyNamespace.IService),
                        new BasicHttpBinding(), baseAddress);
host.Open();

You can download the 10.7 Lion JDK from http://connect.apple.com.

1. Sign in and click the java section on the right.

2. The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.

3. At the time of writing the JDK ended up here:

   /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home

4. Open up eclipse preferences and go to Java --> Installed JREs page

5. Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location

6. At the time of writing Search is not aware of the new JDK location; we we will need to click on the Add button

7. From the Add JRE wizard choose "MacOS X VM" for the JRE Type

8. For the JRE Definition Page we need to fill in the following:

   • JRE Home: /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home

9. The other fields will now auto fill, with the default JRE name being "Home". You can quickly correct this to something more meaningful:

   • JRE name: System JDK

10. Finish the wizard and return to the Installed JREs page

11. Choose "System JDK" from the list

12. You can now develop normally with:

    • javadocs correctly shown for base classes
    • source code correctly shown when debugging

With a React Native running in the emulator,
Press ctrl+m (for Linux, I suppose it's the same for Windows and ?+m for Mac OS X) or run the following in terminal:

adb shell input keyevent 82

The language attribute has been deprecated for a long time, and should not be used.

When W3C was working on HTML5, they discovered all browsers have "text/javascript" as the default script type, so they standardized it to be the default value. Hence, you don't need type either.

For pages in XHTML 1.0 or HTML 4.01 omitting type is considered invalid. Try validating the following:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<script src="http://example.com/test.js"></script>
</head>
<body/>
</html>

You will be informed of the following error:

Line 4, Column 41: required attribute "type" not specified

So if you're a fan of standards, use it. It should have no practical effect, but, when in doubt, may as well go by the spec.

If you use String concatenation in a loop, something like this,

String s = "";
for (int i = 0; i < 100; i++) {
    s += ", " + i;
}

then you should use a StringBuilder (not StringBuffer) instead of a String, because it is much faster and consumes less memory.

If you have a single statement,

String s = "1, " + "2, " + "3, " + "4, " ...;

then you can use Strings, because the compiler will use StringBuilder automatically.

For people using .NET can use IPAddress class to parse IPv4/IPv6 string and store it as a VARBINARY(16). Can use the same class to convert byte[] to string. If want to convert the VARBINARY in SQL:

--SELECT 
--  dbo.varbinaryToIpString(CAST(0x7F000001 AS VARBINARY(4))) IPv4,
--  dbo.varbinaryToIpString(CAST(0x20010DB885A3000000008A2E03707334 AS VARBINARY(16))) IPv6

--ALTER 
CREATE
FUNCTION dbo.varbinaryToIpString
(
    @varbinaryValue VARBINARY(16)
)
RETURNS VARCHAR(39)
AS
BEGIN
    IF @varbinaryValue IS NULL
        RETURN NULL
    IF DATALENGTH(@varbinaryValue) = 4
    BEGIN

            CONVERT(VARCHAR(3), CONVERT(INT, SUBSTRING(@varbinaryValue, 3, 1))) + '.' +
            CONVERT(VARCHAR(3), CONVERT(INT, SUBSTRING(@varbinaryValue, 4, 1)))
    END
    IF DATALENGTH(@varbinaryValue) = 16

    END

A good approach to solving this problem is to first write the code required to get one result, then incorporate threading code to parallelize the application.

In a perfect world this would simply mean simultaneously starting 100,000 threads which output their results into a dictionary or list for later processing, but in practice you are limited in how many parallel HTTP requests you can issue in this fashion. Locally, you have limits in how many sockets you can open concurrently, how many threads of execution your Python interpreter will allow. Remotely, you may be limited in the number of simultaneous connections if all the requests are against one server, or many. These limitations will probably necessitate that you write the script in such a way as to only poll a small fraction of the URLs at any one time (100, as another poster mentioned, is probably a decent thread pool size, although you may find that you can successfully deploy many more).

You can follow this design pattern to resolve the above issue:

1. Start a thread which launches new request threads until the number of currently running threads (you can track them via threading.active_count() or by pushing the thread objects into a data structure) is >= your maximum number of simultaneous requests (say 100), then sleeps for a short timeout. This thread should terminate when there is are no more URLs to process. Thus, the thread will keep waking up, launching new threads, and sleeping until your are finished.
2. Have the request threads store their results in some data structure for later retrieval and output. If the structure you are storing the results in is a list or dict in CPython, you can safely append or insert unique items from your threads without locks, but if you write to a file or require in more complex cross-thread data interaction you should use a mutual exclusion lock to protect this state from corruption.

I would suggest you use the threading module. You can use it to launch and track running threads. Python's threading support is bare, but the description of your problem suggests that it is completely sufficient for your needs.

Finally, if you'd like to see a pretty straightforward application of a parallel network application written in Python, check out ssh.py. It's a small library which uses Python threading to parallelize many SSH connections. The design is close enough to your requirements that you may find it to be a good resource.

UPDATE users
SET first_name = CONCAT(UCASE(LEFT(first_name, 1)), 
                             LCASE(SUBSTRING(first_name, 2)))
,last_name = CONCAT(UCASE(LEFT(last_name, 1)), 
                             LCASE(SUBSTRING(last_name, 2)));

Try:

h1 {
    margin-top: 0;
}

You're seeing the effects of margin collapsing.

Parameters starting with - or -- are usually considered optional. All other parameters are positional parameters and as such required by design (like positional function arguments). It is possible to require optional arguments, but this is a bit against their design. Since they are still part of the non-positional arguments, they will still be listed under the confusing header “optional arguments” even if they are required. The missing square brackets in the usage part however show that they are indeed required.

See also the documentation:

In general, the argparse module assumes that flags like -f and --bar indicate optional arguments, which can always be omitted at the command line.

Note: Required options are generally considered bad form because users expect options to be optional, and thus they should be avoided when possible.

That being said, the headers “positional arguments” and “optional arguments” in the help are generated by two argument groups in which the arguments are automatically separated into. Now, you could “hack into it” and change the name of the optional ones, but a far more elegant solution would be to create another group for “required named arguments” (or whatever you want to call them):

parser = argparse.ArgumentParser(description='Foo')
parser.add_argument('-o', '--output', help='Output file name', default='stdout')
requiredNamed = parser.add_argument_group('required named arguments')
requiredNamed.add_argument('-i', '--input', help='Input file name', required=True)
parser.parse_args(['-h'])

usage: [-h] [-o OUTPUT] -i INPUT

Foo

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        Output file name

required named arguments:
  -i INPUT, --input INPUT
                        Input file name

I had the same problem. Couldn't access http://localhost/joomla neither.
and I did not quite understand the other answers.
The simple solution for me:

1. stop all actions in xampp (I had apache and mysql running. apache on port 80 and 7000something)
2. quit firefox
3. restart the actions (apache and mysql)
4. restart firefox.
5. open http://localhost/phpmyadmin (or http://localhost/joomla - whatever it be)
6. voila!

Now apache runs on port 80 and 443 and mysql on 3306.

I would use

WHERE columnName LIKE '%[%]%'

SQL Server stores string summary statistics for use in estimating the number of rows that will match a LIKE clause. The cardinality estimates can be better and lead to a more appropriate plan when the square bracket syntax is used.

The response to this Connect Item states

We do not have support for precise cardinality estimation in the presence of user defined escape characters. So we probably get a poor estimate and a poor plan. We'll consider addressing this issue in a future release.

An example

CREATE TABLE T
(
X VARCHAR(50),
Y CHAR(2000) NULL
)

CREATE NONCLUSTERED INDEX IX ON T(X)

INSERT INTO T (X)
SELECT TOP (5) '10% off'
FROM master..spt_values
UNION ALL
SELECT  TOP (100000)  'blah'
FROM master..spt_values v1,  master..spt_values v2


SET STATISTICS IO ON;
SELECT *
FROM T 
WHERE X LIKE '%[%]%'

SELECT *
FROM T
WHERE X LIKE '%\%%' ESCAPE '\'

Shows 457 logical reads for the first query and 33,335 for the second.

For nearly all programming purposes, VBA and VB 6.0 are the same thing.

VBA cannot compile your program into an executable binary. You'll always need the host (a Word file and MS Word, for example) to contain and execute your project. You'll also not be able to create COM DLLs with VBA.

Apart from that, there is a difference in the IDE - the VB 6.0 IDE is more powerful in comparison. On the other hand, you have tight integration of the host application in VBA. Application-global objects (like "ActiveDocument") and events are available without declaration, so application-specific programming is straight-forward.

Still, nothing keeps you from firing up Word, loading the VBA IDE and solving a problem that has no relation to Word whatsoever. I'm not sure if there is anything that VB 6.0 can do (technically), and VBA cannot. I'm looking for a comparison sheet on the MSDN though.

On Linux/Unix servers, you can execute a job in the background by using proc_open:

$descriptorspec = array(
   array('pipe', 'r'),               // stdin
   array('file', 'myfile.txt', 'a'), // stdout
   array('pipe', 'w'),               // stderr
);

$proc = proc_open('php email_script.php &', $descriptorspec, $pipes);

The & being the important bit here. The script will continue even if the original script has ended.

man printf.1 has a note at the bottom: "...your shell may have its own version of printf...". This question is tagged for bash, but if at all possible, I try to write scripts portable to any shell. dash is usually a good minimum baseline for portability - so the answer here works in bash, dash, & zsh. If a script works in those 3, it's most likely portable to just about anywhere.

The latest implementation of printf in dash^[1] doesn't colorize output given a %s format specifier with an ANSI escape character \e -- but, a format specifier %b combined with octal \033 (equivalent to an ASCII ESC) will get the job done. Please comment for any outliers, but AFAIK, all shells have implemented printf to use the ASCII octal subset at a bare minimum.

To the title of the question "Using colors with printf", the most portable way to set formatting is to combine the %b format specifier for printf (as referenced in an earlier answer from @Vlad) with an octal escape \033.

portable-color.sh

#/bin/sh
P="\033["
BLUE=34
printf "-> This is %s %-6s %s text \n" $P"1;"$BLUE"m" "blue" $P"0m"
printf "-> This is %b %-6s %b text \n" $P"1;"$BLUE"m" "blue" $P"0m"

Outputs:

$ ./portable-color.sh
-> This is \033[1;34m blue   \033[0m text
-> This is  blue    text

...and 'blue' is blue in the second line.

The %-6s format specifier from the OP is in the middle of the format string between the opening & closing control character sequences.

The answer is straightforward. Just implement OnScrollListenerand hide/show your toolbar in the listener. For example, if you have listview/recyclerview/gridview, then follow the example.

In your MainActivity Oncreate method, initialize the toolbar.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        if (toolbar != null) {
            setSupportActionBar(toolbar);
            getSupportActionBar().setDisplayShowHomeEnabled(true);
        }
}

And then implement the OnScrollListener

public RecyclerView.OnScrollListener onScrollListener = new RecyclerView.OnScrollListener() {
        boolean hideToolBar = false;
        @Override
        public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);
            if (hideToolBar) {
                ((ActionBarActivity)getActivity()).getSupportActionBar().hide();
            } else {
                ((ActionBarActivity)getActivity()).getSupportActionBar().show();
            }
        }

        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
            if (dy > 20) {
                hideToolBar = true;

            } else if (dy < -5) {
                hideToolBar = false;
            }
        }
    };

I got the idea from: https://stackoverflow.com/a/27063901/1079773

You can check out this solution by AJ. It's pretty straightforward, just copy and paste the following lines of code.

jQuery.browser = {};
(function () {
    jQuery.browser.msie = false;
    jQuery.browser.version = 0;
    if (navigator.userAgent.match(/MSIE ([0-9]+)\./)) {
        jQuery.browser.msie = true;
        jQuery.browser.version = RegExp.$1;
    }
})();

Reference:

• $.browser on jQuery 1.9.x for legacy IE detection

And that is why you can't create a bot with JavaScript, because your options are limited to what the browser allows you to do. You can't just order a browser that follows the CORS policy, which most browsers follow, to send random requests to other origins and allow you to get the response that simply!

Additionally, if you tried to edit some request headers manually, like origin-header from the developers tools that come with the browsers, the browser will refuse your edit and may send a preflight OPTIONS request.

Here's some swift-code for you to set the line spacing programmatically

let label = UILabel()

let attributedText = NSMutableAttributedString(string: "Your string")
let paragraphStyle = NSMutableParagraphStyle()

//SET THIS:
paragraphStyle.lineSpacing = 4
//OR SET THIS:
paragraphStyle.lineHeightMultiple = 4

//Or set both :)

let range = NSMakeRange(0, attributedText.length)
attributedText.addAttributes([NSParagraphStyleAttributeName : paragraphStyle], range: range)
label.attributedText = attributedText

@blytung Has a nice function to replace that function

<?php
$url = "http://www.example.org/";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$contents = curl_exec($ch);
if (curl_errno($ch)) {
  echo curl_error($ch);
  echo "\n<br />";
  $contents = '';
} else {
  curl_close($ch);
}

if (!is_string($contents) || !strlen($contents)) {
echo "Failed to get contents.";
$contents = '';
}

echo $contents;
?>    

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

Here is an example using ng-messages (available in angular 1.3) and a custom directive.

Validation message is displayed on blur for the first time user leaves the input field, but when he corrects the value, validation message is removed immediately (not on blur anymore).

JavaScript

myApp.directive("validateOnBlur", [function() {
    var ddo = {
        restrict: "A",
        require: "ngModel",
        scope: {},
        link: function(scope, element, attrs, modelCtrl) {
            element.on('blur', function () {
                modelCtrl.$showValidationMessage = modelCtrl.$dirty;
                scope.$apply();
            });
        }
    };
    return ddo;
}]);

HTML

<form name="person">
    <input type="text" ng-model="item.firstName" name="firstName" 
        ng-minlength="3" ng-maxlength="20" validate-on-blur required />
    <div ng-show="person.firstName.$showValidationMessage" ng-messages="person.firstName.$error">
        <span ng-message="required">name is required</span>
        <span ng-message="minlength">name is too short</span>
        <span ng-message="maxlength">name is too long</span>
    </div>
</form>

PS. Don't forget to download and include ngMessages in your module:

var myApp = angular.module('myApp', ['ngMessages']);

resolve the url like this href="<%=ResolveUrl("~/favicon.ico")%>"

There are tcpdump filters for HTTP GET & HTTP POST (or for both plus message body):

• Run man tcpdump | less -Ip examples to see some examples

• Here’s a tcpdump filter for HTTP GET (GET = 0x47, 0x45, 0x54, 0x20):

  sudo tcpdump -s 0 -A 'tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420'
  

• Here’s a tcpdump filter for HTTP POST (POST = 0x50, 0x4f, 0x53, 0x54):

  sudo tcpdump -s 0 -A 'tcp dst port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354)'
  

• Monitor HTTP traffic including request and response headers and message body (source):

  tcpdump -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
  tcpdump -X -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
  

For more information on the bit-twiddling in the TCP header see: String-Matching Capture Filter Generator (link to Sake Blok's explanation).

I used this font size control width

.home_footer1::after {
color: transparent;
background-image: url('images/icon-mail.png');      
background-size: 100%;      
content: ".......................................";
font-size: 30pt;
}

I wanted to add another option for those getting to this thread via Google. I needed to accomplish this, but wanted to retain my auto-increment value which truncate() resets. I also didn't want to use DB:: anything because I wanted to operate directly off of the model object. So, I went with this:

Model::whereNotNull('id')->delete();

Obviously the column will have to actually exists, but in a standard, out-of-the-box Eloquent model, the id column exists and is never null. I don't know if this is the best choice, but it works for my purposes.

You can get deadlocks on more than just row locks, e.g. see this. The scripts may be competing for other resources, such as index blocks.

I've gotten around this in the past by engineering the parallelism in such a way that different instances are working on portions of the workload that are less likely to affect blocks that are close to each other; for example, for an update of a large table, instead of setting up the parallel slaves using something like MOD(n,10), I'd use TRUNC(n/10) which mean that each slave worked on a contiguous set of data.

There are, of course, much better ways of splitting up a job for parallelism, e.g. DBMS_PARALLEL_EXECUTE.

Not sure why you're getting "PL/SQL successfully completed", perhaps your scripts are handling the exception?

You need to add the PHP directory to your path. On the command line (e.g. in a batch file), it would look like this:

SET PATH=%PATH%;C:\your\wamp\path\php

if in doubt, it's the directory containing the php.exe.

You can also pre-set the path in Windows' control panel. See here on how to do this in Windows 7 for example.

Be aware that if you call the PHP executable from an arbitrary directory, that directory will be the working directory. You may need to adjust your scripts so they use the proper directories for their file operations (if there are any).

Well, all the answers before aren't entirely correct. 2 of major browsers don't support those 2 properties (IE is one of them) or use them differently.

Better solution (supported by most browsers, but I didn't check Safari):

var canvas = document.getElementById('mycanvas');
var width = canvas.scrollWidth;
var height = canvas.scrollHeight;

At least I get correct values with scrollWidth and -Height and MUST set canvas.width and height when it is resized.

Just as Oded has answered. You need to have this sort of detection functionality in javascript.

I've struggled with this myself and realized that the offset is not enough. It does not give you any information about daylight saving for example. I ended up writing some code to map to zoneinfo database keys.

By checking several dates around a year you can more accurately determine a timezone.

Try the script here: http://jsfiddle.net/pellepim/CsNcf/

Simply change your system timezone and click run to test it. If you are running chrome you need to do each test in a new tab though (and safar needs to be restarted to pick up timezone changes).

If you want more details of the code check out: https://bitbucket.org/pellepim/jstimezonedetect/

Usage:

select replace_foreign_key('user_rates_posts', 'post_id', 'ON DELETE CASCADE');

Function:

CREATE OR REPLACE FUNCTION 
    replace_foreign_key(f_table VARCHAR, f_column VARCHAR, new_options VARCHAR) 
RETURNS VARCHAR
AS $$
DECLARE constraint_name varchar;
DECLARE reftable varchar;
DECLARE refcolumn varchar;
BEGIN

SELECT tc.constraint_name, ccu.table_name AS foreign_table_name, ccu.column_name AS foreign_column_name 
FROM 
    information_schema.table_constraints AS tc 
    JOIN information_schema.key_column_usage AS kcu
      ON tc.constraint_name = kcu.constraint_name
    JOIN information_schema.constraint_column_usage AS ccu
      ON ccu.constraint_name = tc.constraint_name
WHERE constraint_type = 'FOREIGN KEY' 
   AND tc.table_name= f_table AND kcu.column_name= f_column
INTO constraint_name, reftable, refcolumn;

EXECUTE 'alter table ' || f_table || ' drop constraint ' || constraint_name || 
', ADD CONSTRAINT ' || constraint_name || ' FOREIGN KEY (' || f_column || ') ' ||
' REFERENCES ' || reftable || '(' || refcolumn || ') ' || new_options || ';';

RETURN 'Constraint replaced: ' || constraint_name || ' (' || f_table || '.' || f_column ||
 ' -> ' || reftable || '.' || refcolumn || '); New options: ' || new_options;

END;
$$ LANGUAGE plpgsql;

Be aware: this function won't copy attributes of initial foreign key. It only takes foreign table name / column name, drops current key and replaces with new one.

This will drown here, but I fixed my problems with this:

As far as I have found out, there is a faulty file in /usr/local/lib called libsqlite3.so.0 which points to libsqlite3.so.0.8.6. It's been installed through the php7.3-* packages as far as I can tell.

I renamed the file in case it was needed for something. With the command:

cd /usr/local/lib sudo mv libsqlite3.so.0 ./libsqlite3.so.0.back

But you can also just delete it: rm libsqlite3.so.0

The thread that lead me to the answer: link

This solved my problems, and I hope they solve yours as well :)

Other way for get a list just local branch is:

git branch -a | grep -v 'remotes'

I'd go with the following:

Select max(start_ts) 
from db 
where trunc(start_ts) =  date'13-may-2016'

Here is a simple, compact and easy to understand method I use.
First, add a service in your js.

app.factory('Helpers', [ function() {
      // Helper service body

        var o = {
        Helpers: []

        };

        // Dummy function with parameter being passed
        o.getFooBar = function(para) {

            var valueIneed = para + " " + "World!";

            return valueIneed;

          };

        // Other helper functions can be added here ...

        // And we return the helper object ...
        return o;

    }]);

Then, in your controller, inject your helper object and use any available function with something like the following:

app.controller('MainCtrl', [

'$scope',
'Helpers',

function($scope, Helpers){

    $scope.sayIt = Helpers.getFooBar("Hello");
    console.log($scope.sayIt);

}]);

public static boolean copyFile(InputStream inputStream, OutputStream out) {
    byte buf[] = new byte[1024];
    int len;
    long startTime=System.currentTimeMillis();

    try {
        while ((len = inputStream.read(buf)) != -1) {
            out.write(buf, 0, len);
        }

        long endTime=System.currentTimeMillis()-startTime;
        Log.v("","Time taken to transfer all bytes is : "+endTime);
        out.close();
        inputStream.close();

    } catch (IOException e) {

        return false;
    }
    return true;
}

What you are trying to achieve is equivalent to

interface Event {
   name: string;
   dateCreated: string;
   type: string;
}

interface UserEvent extends Event {
   UserId: string; 
}

The way you defined the types does not allow for specifying inheritance, however you can achieve something similar using intersection types, as artem pointed out.

For Linux (I am using Fedora 30) the Shortcut is (Window/Start + Space) Try that and tell me. That works for me

It's also helpful to place the badge inline if you want to apply your own CSS to it. But do remember that you agreed to show Google's Terms and conditions when you registered for an API key - so don't hide it, please. And while it is possible to make the badge disappear completely with CSS, we wouldn't recommend it.

Here is an example that uses scipy.optimize to fit a non-linear functions like a Gaussian, even when the data is in a histogram that isn't well ranged, so that a simple mean estimate would fail. An offset constant also would cause simple normal statistics to fail ( just remove p[3] and c[3] for plain gaussian data).

from pylab import *
from numpy import loadtxt
from scipy.optimize import leastsq

fitfunc  = lambda p, x: p[0]*exp(-0.5*((x-p[1])/p[2])**2)+p[3]
errfunc  = lambda p, x, y: (y - fitfunc(p, x))

filename = "gaussdata.csv"
data     = loadtxt(filename,skiprows=1,delimiter=',')
xdata    = data[:,0]
ydata    = data[:,1]

init  = [1.0, 0.5, 0.5, 0.5]

out   = leastsq( errfunc, init, args=(xdata, ydata))
c = out[0]

print "A exp[-0.5((x-mu)/sigma)^2] + k "
print "Parent Coefficients:"
print "1.000, 0.200, 0.300, 0.625"
print "Fit Coefficients:"
print c[0],c[1],abs(c[2]),c[3]

plot(xdata, fitfunc(c, xdata))
plot(xdata, ydata)

title(r'$A = %.3f\  \mu = %.3f\  \sigma = %.3f\ k = %.3f $' %(c[0],c[1],abs(c[2]),c[3]));

show()

Output:

Jon, a lot of opinion has been given that didn't correctly answer your question.

I will give MY OPINION and then tell you how to do exactly what you asked for.

I see no reason why an assembly couldn't have its own config file. Why is the first level of atomicy (is that a real word?) be at the application level? Why not at the solution level? It's an arbitrary, best-guess decision and as such, an OPINION. If you were to write a logging library and wanted to include a configuration file for it, that would be used globally, why couldn't you hook into the built-in settings functionality? We've all done it ... tried to provide "powerful" functionality to other developers. How? By making assumptions that inherently translated to restrictions. That's exactly what MS did with the settings framework, so you do have to "fool it" a little.

To directly answer your question, simply add the configuration file manually (xml) and name it to match your library and to include the "config" extension. Example:

MyDomain.Mylibrary.dll.Config

Next, use the ConfigurationManager to load the file and access settings:

string assemblyPath = new Uri(Assembly.GetExecutingAssembly().CodeBase).AbsolutePath;
Configuration cfg = ConfigurationManager.OpenExeConfiguration(assemblyPath);
string result = cfg.AppSettings.Settings["TEST_SETTING"].Value;

Note that this fully supports the machine.config heierarchy, even though you've explicitly chosen the app config file. In other words, if the setting isn't there, it will resolve higher. Settings will also override machine.config entries.

Thanks for the direction from the above two answerers. James Thompson's suggestion worked best for Windows users.

1. Go to where your R program is installed. This is referred to as R_Home in the literature. Once you find it, go to the /etc subdirectory.

   C:\R\R-2.10.1\etc
   

2. Select the file in this folder named Rprofile.site. I open it with VIM. You will find this is a bare-bones file with less than 20 lines of code. I inserted the following inside the code:

   # my custom library path
   .libPaths("C:/R/library")
   

   (The comment added to keep track of what I did to the file.)

3. In R, typing the .libPaths() function yields the first target at C:/R/Library

NOTE: there is likely more than one way to achieve this, but other methods I tried didn't work for some reason.

Use push_back():

std::string y("Hello worl");
y.push_back('d')
std::cout << y;

With regards to your second attempt, did you try using vertical align ? Either

<td valign="bottom">

or with css

vertical-align:bottom

This is all you need to do:

$((COUNTER++))

Here's an excerpt from Learning the bash Shell, 3rd Edition, pp. 147, 148:

bash arithmetic expressions are equivalent to their counterparts in the Java and C languages.[9] Precedence and associativity are the same as in C. Table 6-2 shows the arithmetic operators that are supported. Although some of these are (or contain) special characters, there is no need to backslash-escape them, because they are within the $((...)) syntax.

..........................

The ++ and - operators are useful when you want to increment or decrement a value by one.[11] They work the same as in Java and C, e.g., value++ increments value by 1. This is called post-increment; there is also a pre-increment: ++value. The difference becomes evident with an example:

$ i=0
$ echo $i
0
$ echo $((i++))
0
$ echo $i
1
$ echo $((++i))
2
$ echo $i
2

See http://www.safaribooksonline.com/a/learning-the-bash/7572399/

In some brief tests I have found a combination of the two to be better in what I would call reasonably intensive Math:

Type: List<double[]>

Type: List<List<double>>

Time: 00:00:05.7941351

Type: double[rows * columns]

Time: 00:00:06.0547118

Running the Code:

int rows = 10000;
int columns = 10000;

IMatrix Matrix = new IMatrix(rows, columns);

Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();


for (int r = 0; r < Matrix.Rows; r++)
    for (int c = 0; c < Matrix.Columns; c++)
        Matrix[r, c] = Math.E;

for (int r = 0; r < Matrix.Rows; r++)
    for (int c = 0; c < Matrix.Columns; c++)
        Matrix[r, c] *= -Math.Log(Math.E);


stopwatch.Stop();

I do wish we had some top notch Hardware Accelerated Matrix Classes like the .NET Team have done with the System.Numerics.Vectors Class!

C# could be the best ML Language with a bit more work in this area!

Referencing means taking the address of an existing variable (using &) to set a pointer variable. In order to be valid, a pointer has to be set to the address of a variable of the same type as the pointer, without the asterisk:

int  c1;
int* p1;
c1 = 5;
p1 = &c1;
//p1 references c1

Dereferencing a pointer means using the * operator (asterisk character) to retrieve the value from the memory address that is pointed by the pointer: NOTE: The value stored at the address of the pointer must be a value OF THE SAME TYPE as the type of variable the pointer "points" to, but there is no guarantee this is the case unless the pointer was set correctly. The type of variable the pointer points to is the type less the outermost asterisk.

int n1;
n1 = *p1;

Invalid dereferencing may or may not cause crashes:

• Dereferencing an uninitialized pointer can cause a crash
• Dereferencing with an invalid type cast will have the potential to cause a crash.
• Dereferencing a pointer to a variable that was dynamically allocated and was subsequently de-allocated can cause a crash
• Dereferencing a pointer to a variable that has since gone out of scope can also cause a crash.

Invalid referencing is more likely to cause compiler errors than crashes, but it's not a good idea to rely on the compiler for this.

The problem here is that I don't know what is expected. With your current setup, invoking the plugin on the command line would just work:

$ mvn exec:exec
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO]    task-segment: [exec:exec]
[INFO] ------------------------------------------------------------------------
[INFO] [exec:exec {execution: default-cli}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...

The global configuration is used, the hostname command is executed (laptop is my hostname). In other words, the plugin works as expected.

Now, if you want a plugin to get executed as part of the build, you have to bind a goal on a specific phase. For example, to bind it on compile:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.1.1</version>
    <executions>
      <execution>
        <id>some-execution</id>
        <phase>compile</phase>
        <goals>
          <goal>exec</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
      <executable>hostname</executable>
    </configuration>
  </plugin>

And then:

$ mvn compile
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO]    task-segment: [compile]
[INFO] ------------------------------------------------------------------------

[INFO] [exec:exec {execution: some-execution}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...

Note that you can specify a configuration inside an execution.

as per the Chart js documentation page tick configuration section. you can format the value of each tick using the callback function. for example I wanted to change locale of displayed dates to be always German. in the ticks parts of the axis options

ticks: {
    callback: function(value) { 
        return new Date(value).toLocaleDateString('de-DE', {month:'short', year:'numeric'}); 
    },
},

If number is separated by "." and decimals by "," (1.200.000,00) in calling gsub you must set fixed=TRUE as.numeric(gsub(".","",y,fixed=TRUE))

This is probably a habit learned from C, to avoid this sort of typo (single = instead of a double ==):

if (object = null) {

The convention of putting the constant on the left side of == isn't really useful in Java since Java requires that the expression in an if evaluate to a boolean value, so unless the constant is a boolean, you'd get a compilation error either way you put the arguments. (and if it is a boolean, you shouldn't be using == anyway...)

The C++ committee took one step forward (scoping enums out of global namespace) and fifty steps back (no enum type decay to integer). Sadly, enum class is simply not usable if you need the value of the enum in any non-symbolic way.

The best solution is to not use it at all, and instead scope the enum yourself using a namespace or a struct. For this purpose, they are interchangable. You will need to type a little extra when refering to the enum type itself, but that will likely not be often.

struct TextureUploadFormat {
    enum Type : uint32 {
        r,
        rg,
        rgb,
        rgba,
        __count
    };
};

// must use ::Type, which is the extra typing with this method; beats all the static_cast<>()
uint32 getFormatStride(TextureUploadFormat::Type format){
    const uint32 formatStride[TextureUploadFormat::__count] = {
        1,
        2,
        3,
        4
    };
    return formatStride[format]; // decays without complaint
}

Assuming that the program cannot be redesigned to avoid the cast (ref. Keith Thomson's answer):

To cast from size_t to int you need to ensure that the size_t does not exceed the maximum value of the int. This can be done using std::numeric_limits:

int SizeTToInt(size_t data)
{
    if (data > std::numeric_limits<int>::max())
        throw std::exception("Invalid cast.");
    return std::static_cast<int>(data);
}

If you need to cast from size_t to double, and you need to ensure that you don't lose precision, I think you can use a narrow cast (ref. Stroustrup: The C++ Programming Language, Fourth Edition):

template<class Target, class Source>
Target NarrowCast(Source v)
{
    auto r = static_cast<Target>(v);
    if (static_cast<Source>(r) != v)
        throw RuntimeError("Narrow cast failed.");
    return r;
}

I tested using the narrow cast for size_t-to-double conversions by inspecting the limits of the maximum integers floating-point-representable integers (code uses googletest):

EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() - 2 })), size_t{ IntegerRepresentableBoundary() - 2 });
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() - 1 })), size_t{ IntegerRepresentableBoundary() - 1 });
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() })), size_t{ IntegerRepresentableBoundary() });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 1 }), std::exception);
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 2 })), size_t{ IntegerRepresentableBoundary() + 2 });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 3 }), std::exception);
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 4 })), size_t{ IntegerRepresentableBoundary() + 4 });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 5 }), std::exception);

where

constexpr size_t IntegerRepresentableBoundary()
{
    static_assert(std::numeric_limits<double>::radix == 2, "Method only valid for binary floating point format.");
    return size_t{2} << (std::numeric_limits<double>::digits - 1);
}

That is, if N is the number of digits in the mantissa, for doubles smaller than or equal to 2^N, integers can be exactly represented. For doubles between 2^N and 2^(N+1), every other integer can be exactly represented. For doubles between 2^(N+1) and 2^(N+2) every fourth integer can be exactly represented, and so on.

Try running task manager to determine if your program is still running.

If it is running then stop it and run it again. the [Error] ld returned 1 exit status will not come back

Yes you can negate the test as SiegeX has already pointed out.

However you shouldn't use regular expressions for this - it can fail if your path contains special characters. Try this instead:

[[ ":$PATH:" != *":$1:"* ]]

I think this is the culprit:

cmd = new SqlCommand(query, con);

DataTable dt = Select(query);

cmd.ExecuteNonQuery();

ddtype.DataSource = dt;

I don't know what that code is supposed to do, but it looks like you want to create an SqlDataReader for that, as explained here and all over the web if you search for "SqlCommand DropDownList DataSource":

cmd = new SqlCommand(query, con);
ddtype.DataSource = cmd.ExecuteReader();

Or you can create a DataTable as explained here:

cmd = new SqlCommand(query, con);

SqlDataAdapter listQueryAdapter = new SqlDataAdapter(cmd);
DataTable listTable = new DataTable();
listQueryAdapter.Fill(listTable);

ddtype.DataSource = listTable;

As akjoshi and Julio say this is about dispatching an Action to update the GUI on the same thread as the GUI item but from the method that is handling the background data. You can see this code in specific form in akjoshi's answer above. This is a general version.

myTextBlock.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal,
                                   new Action(delegate() 
                                      {
                                      myTextBlock.Text = Convert.ToString(myDataObject.getMeData());
                                      }));

The critical part is to call the dispatcher of your UI object - that ensures you have the correct thread.

From personal experience it seems much easier to create and use the Action inline like this. Declaring it at class level gave me lots of problems with static/non-static contexts.

Thanks,

Assume s = socket.socket() The server can be bound by following methods: Method 1:

host = socket.gethostname()
s.bind((host, port))

Method 2:

host = socket.gethostbyname("localhost")  #Note the extra letters "by"
s.bind((host, port))

Method 3:

host = socket.gethostbyname("192.168.1.48")
s.bind((host, port))

If you do not exactly use same method on the client side, you will get the error: socket.error errno 111 connection refused.

So, you have to use on the client side exactly same method to get the host, as you do on the server. For example, in case of client, you will correspondingly use following methods:

Method 1:

host = socket.gethostname() 
s.connect((host, port))

Method 2:

host = socket.gethostbyname("localhost") # Get local machine name
s.connect((host, port))

Method 3:

host = socket.gethostbyname("192.168.1.48") # Get local machine name
s.connect((host, port))

Hope that resolves the problem.

You've installed the version of git-completion.bash from master - in git's development history this is after a commit that split out the __git_ps1 function from the completion functionality into a new file (git-prompt.sh). The commit that introduced this change, which explains the rationale, is af31a456.

I would still suggest that you just source the version of git-completion.bash (or git-prompt.sh) that is bundled with your installation of git.

However, if for some reason you still want to use this functionality by using scripts separately downloaded from master, you should download git-prompt.sh similarly:

curl -o ~/.git-prompt.sh \
    https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh

... and add the following line to your ~/.bash_profile:

source ~/.git-prompt.sh

Then your PS1 variable that includes __git_ps1 '%s' should work fine.

$("#news_gallery li .over").click(function() {
    article = $("#news-article .news-article");
});

Ljava.lang.String;@ is returned where you used string arrays as strings. Employee.getSelectCancel() does not seem to return a String[]

You can check directly at the CSS grammar.

Basically¹, a name must begin with an underscore (_), a hyphen (-), or a letter(a–z), followed by any number of hyphens, underscores, letters, or numbers. There is a catch: if the first character is a hyphen, the second character must² be a letter or underscore, and the name must be at least 2 characters long.

-?[_a-zA-Z]+[_a-zA-Z0-9-]*

In short, the previous rule translates to the following, extracted from the W3C spec.:

In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, or a hyphen followed by a digit. Identifiers can also contain escaped characters and any ISO 10646 character as a numeric code (see next item). For instance, the identifier "B&W?" may be written as "B&W?" or "B\26 W\3F".

Identifiers beginning with a hyphen or underscore are typically reserved for browser-specific extensions, as in -moz-opacity.

¹ It's all made a bit more complicated by the inclusion of escaped unicode characters (that no one really uses).

² Note that, according to the grammar I linked, a rule starting with TWO hyphens, e.g. --indent1, is invalid. However, I'm pretty sure I've seen this in practice.

I would say that first and foremost: be consistent.

I reckon you are almost there with the conventions that you have outlined in your question. A couple of comments though:

Points 1 and 2 are good I reckon.

Point 3 - sadly this is not always possible. Think about how you would cope with a single table foo_bar that has columns foo_id and another_foo_id both of which reference the foo table foo_id column. You might want to consider how to deal with this. This is a bit of a corner case though!

Point 4 - Similar to Point 3. You may want to introduce a number at the end of the foreign key name to cater for having more than one referencing column.

Point 5 - I would avoid this. It provides you with little and will become a headache when you want to add or remove columns from a table at a later date.

Some other points are:

Index Naming Conventions

You may wish to introduce a naming convention for indexes - this will be a great help for any database metadata work that you might want to carry out. For example you might just want to call an index foo_bar_idx1 or foo_idx1 - totally up to you but worth considering.

Singular vs Plural Column Names

It might be a good idea to address the thorny issue of plural vs single in your column names as well as your table name(s). This subject often causes big debates in the DB community. I would stick with singular forms for both table names and columns. There. I've said it.

The main thing here is of course consistency!

window.location.href = "/somewhere/else";

They are user-defined signals, so they aren't triggered by any particular action. You can explicitly send them programmatically:

#include <signal.h>

kill(pid, SIGUSR1);

where pid is the process id of the receiving process. At the receiving end, you can register a signal handler for them:

#include <signal.h>

void my_handler(int signum)
{
    if (signum == SIGUSR1)
    {
        printf("Received SIGUSR1!\n");
    }
}

signal(SIGUSR1, my_handler);

Oftentimes hooking refers to Win32 message hooking or the Linux/OSX equivalents, but more generically hooking is simply notifying another object/window/program/etc that you want to be notified when a specified action happens. For instance: Having all windows on the system notify you as they are about to close.

As a general rule, hooking is somewhat hazardous since doing it without understanding how it affects the system can lead to instability or at the very leas unexpected behaviour. It can also be VERY useful in certain circumstances, thought. For instance: FRAPS uses it to determine which windows it should show it's FPS counter on.

Be careful when you make a class "final". Because if you want to write an unit test for a final class, you cannot subclass this final class in order to use the dependency-breaking technique "Subclass and Override Method" described in Michael C. Feathers' book "Working Effectively with Legacy Code". In this book, Feathers said, "Seriously, it is easy to believe that sealed and final are a wrong-headed mistake, that they should never have been added to programming languages. But the real fault lies with us. When we depend directly on libraries that are out of our control, we are just asking for trouble."

Disabling user-scalable (namely, the ability to double tap to zoom) allows the browser to reduce the click delay. In touch-enable browsers, when the user expects the double tap to zoom, the browser generally waits 300ms before firing the click event, waiting to see if the user will double tap. Disabling user-scalable allows for the Chrome browser to fire the click event immediately, allowing for a better user experience.

Jackson has to know in what order to pass fields from a JSON object to the constructor. It is not possible to access parameter names in Java using reflection - that's why you have to repeat this information in annotations.

The original conio.h was implemented by Borland, so its not a part of the C Standard Library nor is defined by POSIX.

But here is an implementation for Linux that uses ncurses to do the job.

You can use find option to select an element inside another. For example, to find an element with id txtName in a particular div, you can use like

Most of the answers suggest either using a loop with equals to check if the enum exists or using try/catch with enum.valueOf(). I wanted to know which method is faster and tried it. I am not very good at benchmarking, so please correct me if I made any mistakes.

Heres the code of my main class:

    package enumtest;

public class TestMain {

    static long timeCatch, timeIterate;
    static String checkFor;
    static int corrects;

    public static void main(String[] args) {
        timeCatch = 0;
        timeIterate = 0;
        TestingEnum[] enumVals = TestingEnum.values();
        String[] testingStrings = new String[enumVals.length * 5];
        for (int j = 0; j < 10000; j++) {
            for (int i = 0; i < testingStrings.length; i++) {
                if (i % 5 == 0) {
                    testingStrings[i] = enumVals[i / 5].toString();
                } else {
                    testingStrings[i] = "DOES_NOT_EXIST" + i;
                }
            }

            for (String s : testingStrings) {
                checkFor = s;
                if (tryCatch()) {
                    ++corrects;
                }
                if (iterate()) {
                    ++corrects;
                }
            }
        }

        System.out.println(timeCatch / 1000 + "us for try catch");
        System.out.println(timeIterate / 1000 + "us for iterate");
        System.out.println(corrects);
    }

    static boolean tryCatch() {
        long timeStart, timeEnd;
        timeStart = System.nanoTime();
        try {
            TestingEnum.valueOf(checkFor);
            return true;
        } catch (IllegalArgumentException e) {
            return false;
        } finally {
            timeEnd = System.nanoTime();
            timeCatch += timeEnd - timeStart;
        }

    }

    static boolean iterate() {
        long timeStart, timeEnd;
        timeStart = System.nanoTime();
        TestingEnum[] values = TestingEnum.values();
        for (TestingEnum v : values) {
            if (v.toString().equals(checkFor)) {
                timeEnd = System.nanoTime();
                timeIterate += timeEnd - timeStart;
                return true;
            }
        }
        timeEnd = System.nanoTime();
        timeIterate += timeEnd - timeStart;
        return false;
    }
}

This means, each methods run 50000 times the lenght of the enum I ran this test multiple times, with 10, 20, 50 and 100 enum constants. Here are the results:

• 10: try/catch: 760ms | iteration: 62ms
• 20: try/catch: 1671ms | iteration: 177ms
• 50: try/catch: 3113ms | iteration: 488ms
• 100: try/catch: 6834ms | iteration: 1760ms

These results were not exact. When executing it again, there is up to 10% difference in the results, but they are enough to show, that the try/catch method is far less efficient, especially with small enums.

If the file is large, you may not want to load it entirely into memory at once. This approach avoids that. (Of course, making a dict out of it could still take up some RAM, but it's guaranteed to be smaller than the original file.)

my_dict = {}
for i, line in enumerate(file):
    if (i - 8) % 7:
        continue
    k, v = line.split("\t")[:3:2]
    my_dict[k] = v

Edit: Not sure where I got extend from before. I meant update

The error occurs on some RedHat distributions. The only thing you need to do is to run your application with parameter java.security.egd=file:///dev/urandom:

java -Djava.security.egd=file:///dev/urandom [your command]

INNER JOIN requires there is at least a match in comparing the two tables. For example, table A and table B which implies A ? B (A intersection B).

LEFT OUTER JOIN and LEFT JOIN are the same. It gives all the records matching in both tables and all possibilities of the left table.

Similarly, RIGHT OUTER JOIN and RIGHT JOIN are the same. It gives all the records matching in both tables and all possibilities of the right table.

FULL JOIN is the combination of LEFT OUTER JOIN and RIGHT OUTER JOIN without duplication.

I realise this may have been answered before. However, i had this issue this morning with Environment.Newline not being preserved in the email body. The following is a full (Now Working with Environment.NewLine being preserved) method i use for sending an email through my program.(The Modules.MessageUpdate portion can be skipped as this just writes to a log file i have.) This is located on the main page of my WinForms program.

    private void MasterMail(string MailContents)
    {
        Modules.MessageUpdate(this, ObjApp, EH, 3, 25, "", "", "", 0, 0, 0, 0, "Master Email - MasterMail Called.", "N", MainTxtDict, MessageResourcesTxtDict);

        Outlook.Application OApp = new Outlook.Application();
        //Location of email template to use. Outlook wont include my Signature through this automation so template contains only that.
        string Temp = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + ResourceDetails.DictionaryResources("SigTempEmail", MainTxtDict);

        Outlook.Folder folder = OApp.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderDrafts) as Outlook.Folder;

        //create the email object.
        Outlook.MailItem TestEmail = OApp.CreateItemFromTemplate(Temp, folder) as Outlook.MailItem;

        //Set subject line.
        TestEmail.Subject = "Automation Results";

        //Create Recipients object.
        Outlook.Recipients oRecips = (Outlook.Recipients)TestEmail.Recipients;

        //Set and check email addresses to send to.
        Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add("EmailAddressToSendTo");
        oRecip.Resolve();

        //Set the body of the email. (.HTMLBody for HTML Emails. .Body will preserve "Environment.NewLine")
        TestEmail.Body = MailContents + TestEmail.Body;
        try
        {
            //If outlook is not open, Open it.
            Process[] pName = Process.GetProcessesByName("OUTLOOK.EXE");
            if (pName.Length == 0)
            {
                System.Diagnostics.Process.Start(@"C:\Program Files\Microsoft Office\root\Office16\OUTLOOK.EXE");
            }

            //Send email
            TestEmail.Send();

            //Update logfile - Success.
            Modules.MessageUpdate(this, ObjApp, EH, 1, 17, "", "", "", 0, 0, 0, 0, "Master Email sent.", "Y", MainTxtDict, MessageResourcesTxtDict);
        }
        catch (Exception E)
        {
            //Update LogFile - Fail.
            Modules.MessageUpdate(this, ObjApp, EH, 5, 4, "", "", "", 0, 0, 0, 0, "Master Email - Error Occurred. System says: " + E.Message, "Y", MainTxtDict, MessageResourcesTxtDict);
        }
        finally
        {
            if (OApp != null)
            {
                OApp = null;
            }
            if (folder != null)
            {
                folder = null;
            }
            if (TestEmail != null)
            {
                TestEmail = null;
            }
            GC.Collect();
            GC.WaitForPendingFinalizers();
        }
    }

You can add multiple recipients by either including a "; " between email addresses manually, or in one of my other methods i populate from a Txt file into a dictionary and use that to create the recipients email addresses using the following snippet.

        foreach (KeyValuePair<string, string> kvp in EmailDict)
        {
            Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add(kvp.Value);
            RecipientList += string.Format("{0}; ", kvp.Value);
            oRecip.Resolve();
        }

I hope at least some of this helps someone.

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}

Simply & Easy : JavaScript code :

function JoinedOrNot(){
    var cat = document.getElementById("mySelect");
    if(cat.value == "yes"){
        document.getElementById("mySelect1").disabled = false;
    }else{
        document.getElementById("mySelect1").disabled = true;
    }
}

just add in this line [onChange="JoinedOrNot()"] : <select id="mySelect" onchange="JoinedOrNot()">

it's work fine ;)

One possible explanation is a database trigger that fires for each DROP TABLE statement. To find the trigger, query the _TRIGGERS dictionary views:

select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')

disable any suspicious trigger with

   alter trigger <trigger_name> disable;

and try re-running your DROP TABLE statement

The best solution would be Ctrl+Alt+I.
