You can cycle through the first list and, for every item that isn't in the second list but is in the first list, add it to the third list. E.g:

temp3 = []
for i in temp1:
    if i not in temp2:
        temp3.append(i)
print(temp3)

Try changing the Web Client request authentication part to:

NetworkCredential myCreds = new NetworkCredential(userName, passWord);
client.Credentials = myCreds;

Then make your call, seems to work fine for me.

You can use a MultiBinding combined with the StringFormat property. Usage would resemble the following:

<TextBlock>
    <TextBlock.Text>    
        <MultiBinding StringFormat="{}{0} + {1}">
            <Binding Path="Name" />
            <Binding Path="ID" />
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

Giving Name a value of Foo and ID a value of 1, your output in the TextBlock would then be Foo + 1.

Note: that this is only supported in .NET 3.5 SP1 and 3.0 SP2 or later.

The argument order seems to matter... to exclude subdirectories, I used

robocopy \\source\folder C:\destinationfolder /XD * /MIR

...and that works for me (Windows 10 copy from Windows Server 2016)

main() {
    double a;
    a=3669.0;
    int b;
    b=a;
    printf("b is %d",b);
  
}

output is :b is 3669

when you write b=a; then its automatically converted in int

Nginx works as a front end server, which in this case proxies the requests to a node.js server. Therefore you need to setup an nginx config file for node.

This is what I have done in my Ubuntu box:

Create the file yourdomain.com at /etc/nginx/sites-available/:

vim /etc/nginx/sites-available/yourdomain.com

In it you should have something like:

# the IP(s) on which your node server is running. I chose port 3000.
upstream app_yourdomain {
    server 127.0.0.1:3000;
    keepalive 8;
}

# the nginx server instance
server {
    listen 80;
    listen [::]:80;
    server_name yourdomain.com www.yourdomain.com;
    access_log /var/log/nginx/yourdomain.com.log;

    # pass the request to the node.js server with the correct headers
    # and much more can be added, see nginx config options
    location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;

      proxy_pass http://app_yourdomain/;
      proxy_redirect off;
    }
 }

If you want nginx (>= 1.3.13) to handle websocket requests as well, add the following lines in the location / section:

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

Once you have this setup you must enable the site defined in the config file above:

cd /etc/nginx/sites-enabled/ 
ln -s /etc/nginx/sites-available/yourdomain.com yourdomain.com

Create your node server app at /var/www/yourdomain/app.js and run it at localhost:3000

var http = require('http');

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');

Test for syntax mistakes:

nginx -t

Restart nginx:

sudo /etc/init.d/nginx restart

Lastly start the node server:

cd /var/www/yourdomain/ && node app.js

Now you should see "Hello World" at yourdomain.com

One last note with regards to starting the node server: you should use some kind of monitoring system for the node daemon. There is an awesome tutorial on node with upstart and monit.

For all built-in Python objects (like strings, lists, dicts, functions, etc.), if x is y, then x==y is also True.

Not always. NaN is a counterexample. But usually, identity (is) implies equality (==). The converse is not true: Two distinct objects can have the same value.

Also, is it generally considered better to just use '==' by default, even when comparing int or Boolean values?

You use == when comparing values and is when comparing identities.

When comparing ints (or immutable types in general), you pretty much always want the former. There's an optimization that allows small integers to be compared with is, but don't rely on it.

For boolean values, you shouldn't be doing comparisons at all. Instead of:

if x == True:
    # do something

write:

if x:
    # do something

For comparing against None, is None is preferred over == None.

I've always liked to use 'is' because I find it more aesthetically pleasing and pythonic (which is how I fell into this trap...), but I wonder if it's intended to just be reserved for when you care about finding two objects with the same id.

Yes, that's exactly what it's for.

Your groups_main table has a key column named id. I believe you can only use the USING syntax for the join if the groups_fans table has a key column with the same name, which it probably does not. So instead, try this:

LEFT JOIN groups_fans AS m ON m.group_id = g.id

Or replace group_id with whatever the appropriate column name is in the groups_fans table.

Try this:

foreach (var dept in employees.SelectMany(e => e.Departments))
{
   dept.SomeProperty = null;
   collection.Add(dept);
}

 <item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>

Dont use windowLightStatusBar use instead statusBarColor = @android:color/transparent

iptables(8) has a statistic match module that can be used to match every nth packet. To drop this packet, just append -j DROP.

function MyError(message) {
 this.message = message;
}

MyError.prototype = new Error;

This allows for usage like..

try {
  something();
 } catch(e) {
  if(e instanceof MyError)
   doSomethingElse();
  else if(e instanceof Error)
   andNowForSomethingCompletelyDifferent();
}

I use the following method in my project

            };
            int size = sizeof(codes)/sizeof(int);
            NSMutableArray *array = [[NSMutableArray alloc] init];
            for (int i=0;i<size;++i){
                [array addObject:[NSNumber numberWithInt:codes[i]]];
            }
            codesArray = [array copy];
        }
    }
    return codesArray;
}

Then I just check the error code and show alert if it is in the list

if ([[self networkErrorCodes] containsObject:[NSNumber
numberWithInt:[error code]]]){ 
// Fire Alert View Here
}

But as you can see I commented out codes that I think does not fit to my definition of NO INTERNET. E.g the code of -1012 (Authentication fail.) You may edit the list as you like.

In my project I use it at username/password entering from user. And in my view (physical) network connection errors could be the only reason to show alert view in your network based app. In any other case (e.g. incorrect username/password pair) I prefer to do some custom user friendly animation, OR just repeat the failed attempt again without any attention of the user. Especially if the user didn't explicitly initiated a network call.

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

Add a secondary horizontal axis

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

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

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

   

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

Add a secondary vertical axis

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

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

   • Click the chart.

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

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

     

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

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

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

   A secondary vertical axis is displayed in the chart.

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

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

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

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

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

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

Increasing the heap size is not a "fix" it is a "plaster", 100% temporary. It will crash again in somewhere else. To avoid these issues, write high performance code.

1. Use local variables wherever possible.
2. Make sure you select the correct object (EX: Selection between String, StringBuffer and StringBuilder)
3. Use a good code system for your program(EX: Using static variables VS non static variables)
4. Other stuff which could work on your code.
5. Try to move with multy THREADING

A handy post explaining several mis-understandings about this:

Don't Call The Destructor explicitly

This covers several misconceptions about how the destructor works. Calling it explicitly will not actually destroy your variable, according to the PHP5 doc:

PHP 5 introduces a destructor concept similar to that of other object-oriented languages, such as C++. The destructor method will be called as soon as there are no other references to a particular object, or in any order during the shutdown sequence.

The post above does state that setting the variable to null can work in some cases, as long as nothing else is pointing to the allocated memory.

It looks like you are running something in Windows by double clicking on it. This will execute the program in a new window and close the window when it terminates. No wonder you cannot read the output.

A better way to do this would be to switch to the command prompt. Navigate (cd) to the directory where the program is located and then call it using python. Something like this:

C:\> cd C:\my_programs\
C:\my_programs\> python area.py

Replace my_programs with the actual location of your program and area.py with the name of your python file.

I used Dozer for cloning java objects and it's great at that , Kryo library is another great alternative.

create schema tableName authorization dbo
go
IF OBJECT_ID ('tableName.put_fieldValue', 'P' ) IS NOT NULL 
drop proc tableName.put_fieldValue
go
create proc tableName.put_fieldValue(@fieldValue int) as
declare @tableid int = 0
select @tableid = tableid from table where fieldValue=''
if @tableid = 0 begin
   insert into table(fieldValue) values('')
   select @tableid = scope_identity()
end
return @tableid
go
declare @tablid int = 0
exec @tableid = tableName.put_fieldValue('')

I founded the problem: Just insert the folder without the executable file.
so Instead of:

C:\Program Files (x86)\SumatraPDF\SumatraPDF.exe

you have to write this:

C:\Program Files (x86)\SumatraPDF\

Non-recursive solution, no imports:

def factorial(x):
    return eval(' * '.join(map(str, range(1, x + 1))))

One more (in the future) way to conditionally apply style is by conditionally creating scoped style

<style scoped type="text/css" ng-if="...">

</style>

But nowadays only FireFox supports scoped styles.

I had this error message:

Error: Can't open display: localhost:13.0

This fixed it for me:

export DISPLAY="localhost:10.0"

You can use this too:

export DISPLAY="127.0.0.1:10.0"

If you navigate to where you have installed SQLExpress, e.g.

C:\Program Files\Microsoft SQL Server\110\Tools\Binn

You can run SQLLocalDB.exe and get a list of the all instances installed on your machine.

C:\Program Files\Microsoft SQL Server\110\Tools\Binn>SqlLocalDB.exe info
MSSQLLocalDB
ProjectsV12
v11.0

Then you can get further information on the instance.

Update 2016: seems to be working again.

Update August 2014: No longer works as of recent Chrome versions.

Yeah, the new state of affairs sucks. Fortunately it's not so hard as the other answers imply.

1. Browse in Chrome to chrome://extensions
2. Drag the .user.js file into that page.

Voila. You can also drag files from the downloads footer bar to the extensions tab.

Chrome will automatically create a manifest.json file in the extensions directory that Brock documented.

If you go to http://github.com/my_user_name/my_repo you will see a textbox where you can select the git path to your repository. You'll want to use this!

As a newbie in React world, I came across a similar issues where I could not edit the textarea and struggled with binding. It's worth knowing about controlled and uncontrolled elements when it comes to react.

The value of the following uncontrolled textarea cannot be changed because of value

 <textarea type="text" value="some value"
    onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following uncontrolled textarea can be changed because of use of defaultValue or no value attribute

<textarea type="text" defaultValue="sample" 
    onChange={(event) => this.handleOnChange(event)}></textarea>

<textarea type="text" 
   onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following controlled textarea can be changed because of how value is mapped to a state as well as the onChange event listener

<textarea value={this.state.textareaValue} 
onChange={(event) => this.handleOnChange(event)}></textarea>

Here is my solution using different syntax. I prefer the auto-bind than manual binding however, if I were to not use {(event) => this.onXXXX(event)} then that would cause the content of textarea to be not editable OR the event.preventDefault() does not work as expected. Still a lot to learn I suppose.

class Editor extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      textareaValue: ''
    }
  }
  handleOnChange(event) {
    this.setState({
      textareaValue: event.target.value
    })
  }
  handleOnSubmit(event) {
    event.preventDefault();
    this.setState({
      textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
    })
  }
  render() {
    return <div>
        <form onSubmit={(event) => this.handleOnSubmit(event)}>
          <textarea rows={10} cols={30} value={this.state.textareaValue} 
            onChange={(event) => this.handleOnChange(event)}></textarea>
          <br/>
          <input type="submit" value="Save"/>
        </form>
      </div>
  }
}
ReactDOM.render(<Editor />, document.getElementById("content"));

The versions of libraries are

"babel-cli": "6.24.1",
"babel-preset-react": "6.24.1"
"React & ReactDOM v15.5.4" 

That's because you have the Date in American format in line[i] and UK format in the FormatString.

11/20/2011
M / d/yyyy

I'm guessing you might need to change the FormatString to:

"M/d/yyyy h:mm"

Starting from Matlab 2014b Python functions can be called directly. Use prefix py, then module name, and finally function name like so:

result = py.module_name.function_name(parameter1);

Make sure to add the script to the Python search path when calling from Matlab if you are in a different working directory than that of the Python script.

See more details here.

The answer given by Matt K works perfectly fine.

However it is important to note one thing - If the div you are applying it to has absolute positioning, it wont work. For it to work, do this -

<div style="position:absolute; hei...">
   <div style="position:relative; display: table-cell; vertical-align:middle; hei..."> 
      <!-- here position MUST be relative, this div acts as a wrapper-->
      ...
   </div>
</div>

Just check this:

$(document).ready(function() {
    $(".scroll").click(function(event){
        $('html, body').animate({scrollTop: '+=150px'}, 800);
    });
});

It will make scroller scroll from current position when your element is clicked

And 150px is used to scroll for 150px downwards

I had a similar issue and solved it with a patch to ec2.py and adding some configuration parameters to ec2.ini. The patch takes the value of ec2_key_name, prefixes it with the ssh_key_path, and adds the ssh_key_suffix to the end, and writes out ansible_ssh_private_key_file as this value.

The following variables have to be added to ec2.ini in a new 'ssh' section (this is optional if the defaults match your environment):

[ssh]
# Set the path and suffix for the ssh keys
ssh_key_path = ~/.ssh
ssh_key_suffix = .pem

Here is the patch for ec2.py:

204a205,206
>     'ssh_key_path': '~/.ssh',
>     'ssh_key_suffix': '.pem',
422a425,428
>         # SSH key setup
>         self.ssh_key_path = os.path.expanduser(config.get('ssh', 'ssh_key_path'))
>         self.ssh_key_suffix = config.get('ssh', 'ssh_key_suffix')
> 
1490a1497
>         instance_vars["ansible_ssh_private_key_file"] = os.path.join(self.ssh_key_path, instance_vars["ec2_key_name"] + self.ssh_key_suffix)

I think your error was in calling the function.

In your HTML code, onclick is calling the image() function. However, in your script the function is named imgWindow(). Try changing the onclick to imgWindow().

I don't do much JavaScript so if I have missed something, please let me know.

Good Luck!

after upgrading curl , libcurl and nss , git clone works fine again, so here it is. the update command is as follows

sudo yum update -y nss curl libcurl

var responseData = //Fetch Data
string jsonData = JsonConvert.SerializeObject(responseData, Formatting.None);
System.IO.File.WriteAllText(Server.MapPath("~/JsonData/jsondata.txt"), jsonData);

Another reason could be an outdated version of JDK. I was using jdk version 1.8.0_60, simply updating to the latest version solved the certificate issue.

If someone is interested for the solution for Compact Framework :

return String.Join(" ", thestring.Split(' ').Select(i => i.Substring(0, 1).ToUpper() + i.Substring(1).ToLower()).ToArray());

The difference is that Visibility.Hidden hides the control, but reserves the space it occupies in the layout. So it renders whitespace instead of the control. Visibilty.Collapsed does not render the control and does not reserve the whitespace. The space the control would take is 'collapsed', hence the name.

The exact text from the MSDN:

Collapsed: Do not display the element, and do not reserve space for it in layout.

Hidden: Do not display the element, but reserve space for the element in layout.

Visible: Display the element.

You want to do:

If you don't want the changes and blow everything away:

git reset --hard HEAD~

You probably want to use the assets_base_urls configuration.

framework:
    templating:
        assets_base_urls:
            http:   [http://www.website.com]
            ssl:   [https://www.website.com]

http://symfony.com/doc/current/reference/configuration/framework.html#assets

Note that the configuration is different since Symfony 2.7:

framework:
    # ...
    assets:
        base_urls:
            - 'http://cdn.example.com/'

I assume bash is running on a vt100-compatible terminal in which the user did not explicitly turn off the support for formatting.

First, turn on support for special characters in echo, using -e option. Later, use ansi escape sequence ESC[1m, like:

echo -e "\033[1mSome Text"

More on ansi escape sequences for example here: ascii-table.com/ansi-escape-sequences-vt-100.php

The onkeyup event does "work" as you intend:

The following MySQL statement should modify your column to accept NULLs.

ALTER TABLE `MyTable`
ALTER COLUMN `Col3` varchar(20) DEFAULT NULL

I found another way to convert an object to a byte[], here is my solution:

IEnumerable en = (IEnumerable) myObject;
byte[] myBytes = en.OfType<byte>().ToArray();

This HTML + CSS solution worked for me:

form select:invalid {_x000D_
  color: gray;_x000D_
}_x000D_
_x000D_
form select option:first-child {_x000D_
  color: gray;_x000D_
}_x000D_
_x000D_
form select:invalid option:not(:first-child) {_x000D_
  color: black;_x000D_
}

<form>_x000D_
  <select required>_x000D_
    <option value="">Select Planet...</option>_x000D_
    <option value="earth">Earth</option>_x000D_
    <option value="pandora">Pandora</option>_x000D_
  </select>_x000D_
</form>

Good Luck...

Check out this: Change Streams

January 10, 2018 - Release 3.6

*EDIT: I wrote an article about how to do this https://medium.com/riow/mongodb-data-collection-change-85b63d96ff76

https://docs.mongodb.com/v3.6/changeStreams/

It's new in mongodb 3.6 https://docs.mongodb.com/manual/release-notes/3.6/ 2018/01/10

$ mongod --version
db version v3.6.2

In order to use changeStreams the database must be a Replication Set

More about Replication Sets: https://docs.mongodb.com/manual/replication/

Your Database will be a "Standalone" by default.

How to Convert a Standalone to a Replica Set: https://docs.mongodb.com/manual/tutorial/convert-standalone-to-replica-set/

The following example is a practical application for how you might use this.
* Specifically for Node.

/* file.js */
'use strict'


module.exports = function (
    app,
    io,
    User // Collection Name
) {
    // SET WATCH ON COLLECTION 
    const changeStream = User.watch();  

    // Socket Connection  
    io.on('connection', function (socket) {
        console.log('Connection!');

        // USERS - Change
        changeStream.on('change', function(change) {
            console.log('COLLECTION CHANGED');

            User.find({}, (err, data) => {
                if (err) throw err;

                if (data) {
                    // RESEND ALL USERS
                    socket.emit('users', data);
                }
            });
        });
    });
};
/* END - file.js */

the credit goes for my senior colleague for this:

:> filename

This will not break log files, so you can even use it on syslog, for example.

Building on @joris response above, if you have already established a reference to the subplot, you can use the reference as well. For example,

ax1 = plt.subplot2grid((50,100), (0, 0), colspan=20, rowspan=10)
...

df.plot.barh(ax=ax1, stacked=True)

$arr1 = array(

    array('id'=>1,'name'=>'aA','cat'=>'cc'),
    array('id'=>2,'name'=>'aa','cat'=>'dd'),
    array('id'=>3,'name'=>'bb','cat'=>'cc'),
    array('id'=>4,'name'=>'bb','cat'=>'dd')
);

$result1 = array_msort($arr1, array('name'=>SORT_DESC);

$result2 = array_msort($arr1, array('cat'=>SORT_ASC);

$result3 = array_msort($arr1, array('name'=>SORT_DESC, 'cat'=>SORT_ASC));


function array_msort($array, $cols)
{
    $colarr = array();
    foreach ($cols as $col => $order) {
    $colarr[$col] = array();
    foreach ($array as $k => $row) { $colarr[$col]['_'.$k] = strtolower($row[$col]); }
}

$eval = 'array_multisort(';

foreach ($cols as $col => $order) {
    $eval .= '$colarr[\''.$col.'\'],'.$order.',';
}

$eval = substr($eval,0,-1).');';
eval($eval);
$ret = array();
foreach ($colarr as $col => $arr) {
    foreach ($arr as $k => $v) {
        $k = substr($k,1);
        if (!isset($ret[$k])) $ret[$k] = $array[$k];
        $ret[$k][$col] = $array[$k][$col];
    }
}
return $ret;

Here's the world's fastest routing algorithms compared and proven for correctness:

Here's a google tech talk on the subject:

http://www.youtube.com/watch?v=-0ErpE8tQbw

Here's a implementation of the highway-hierarchies algorithm as discussed by schultes (currently in berlin only, I'm writing the interface and a mobile version is being developed as well):

http://tom.mapsforge.org/

it works:

type HtmlEvent = React.ChangeEvent<HTMLSelectElement>

const onChange: React.EventHandler<HtmlEvent> = 
   (event: HtmlEvent) => { 
       console.log(event.target.value) 
   }

You can create a utility class to check if the class represents any Collection, Map or Array

  public static boolean isCollection(Class<?> rawPropertyType) {
        return Collection.class.isAssignableFrom(rawPropertyType) || 
               Map.class.isAssignableFrom(rawPropertyType) || 
               rawPropertyType.isArray();
 }

oSheet.get_Range("A1", "AS1").Merge();

We Can override the blue color in to our custom color It works for Internet Explorer, Firefox and Chrome:

By using this below following CSS:

option: checked, option: hover {
    Color: #ffffff;
    background: #614767 repeat url("data:image/gif;base64,R0lGODlh8ACgAPAAAGFGZQAAACH5BAAAAAAALAAAAADwAKAAAAL+hI+py+0Po5y02ouz3rz7D4biSJbmiabqyrbuC8fyTNf2jef6zvf+DwwKh8Si8YhMKpfMpvMJjUqn1Kr1is1qt9yu9wsOi8fksvmMTqvX7Lb7DY/L5/S6/Y7P6/f8vv8PGCg4SFhoeIiYqLjI2Oj4CBkpOUlZaXmJmam5ydnp+QkaKjpKWmp6ipqqusra6voKGys7S1tre4ubq7vL2+v7CxwsPExcbHyMnKy8zNzs/AwdLT1NXW19jZ2tvc3d7f0NHi4+Tl5ufo6err7O3u7+Dh8vP09fb3+Pn6+/z9/v/w8woMCBBAsaPIgwocKFDBs6fAgxosSJFCtavIhRVgEAOw");
}

A height of 100% for is, presumably, the height of your browser's inner window, because that is the height of its parent, the page. An auto height will be the minimum height of necessary to contain .

You are running Python 2 code on Python 3. In Python 3, the module has been renamed to http.client.

You could try to run the 2to3 tool on your code, and try to have it translated automatically. References to httplib will automatically be rewritten to use http.client instead.

Open your id_dsa.pub or some_name.pub file with gedit and copy-paste the contents!

Just use:

~/.ssh$ gedit some_name.pub

When you want to pass new information to your application, you need to use POST form. In Razor you can use the following

View Code:

@* By default BeginForm use FormMethod.Post *@
@using(Html.BeginForm("Update")){
     @Html.Hidden("id", Model.Id)
     @Html.Hidden("productid", Model.ProductId)
     @Html.TextBox("qty", Model.Quantity)
     @Html.TextBox("unitrate", Model.UnitRate)
     <input type="submit" value="Update" />
}

Controller's actions

[HttpGet]
public ActionResult Update(){
     //[...] retrive your record object
     return View(objRecord);
}

[HttpPost]
public ActionResult Update(string id, string productid, int qty, decimal unitrate)
{
      if (ModelState.IsValid){
           int _records = UpdatePrice(id,productid,qty,unitrate);
           if (_records > 0){                    {
              return RedirectToAction("Index1", "Shopping");
           }else{                   
                ModelState.AddModelError("","Can Not Update");
           }
      }
      return View("Index1");
 }

Note that alternatively, if you want to use @Html.TextBoxFor(model => model.Quantity) you can either have an input with the name (respectecting case) "Quantity" or you can change your POST Update() to receive an object parameter, that would be the same type as your strictly typed view. Here's an example:

Model

public class Record {
    public string Id { get; set; }
    public string ProductId { get; set; }
    public string Quantity { get; set; }
    public decimal UnitRate { get; set; }
}

View

@using(Html.BeginForm("Update")){
     @Html.HiddenFor(model => model.Id)
     @Html.HiddenFor(model => model.ProductId)
     @Html.TextBoxFor(model=> model.Quantity)
     @Html.TextBoxFor(model => model.UnitRate)
     <input type="submit" value="Update" />
}

Post Action

[HttpPost]
public ActionResult Update(Record rec){ //Alternatively you can also use FormCollection object as well 
   if(TryValidateModel(rec)){
        //update code
   }
   return View("Index1");
}

The extra [ ] on the outside of your second syntax are unnecessary, and possibly confusing. You may use them, but if you must you need to have whitespace between them.

Alternatively:

while [ $stats -gt 300 ] || [ $stats -eq 0 ]

You can handle the fds yourself. The exec in java returns a Process object. Intermittently check if the process is still running. Once it has completed close the processes STDERR, STDIN, and STDOUT streams (e.g. proc.getErrorStream.close()). That will mitigate the leaks.

UDP is a connection-less protocol and is used in protocols like SNMP and DNS in which data packets arriving out of order is acceptable and immediate transmission of the data packet matters.

It is used in SNMP since network management must often be done when the network is in stress i.e. when reliable, congestion-controlled data transfer is difficult to achieve.

It is used in DNS since it does not involve connection establishment, thereby avoiding connection establishment delays.

nginx is useful for forwarding HTTP on many platforms including Windows. It's easy to setup and extend with more advanced configuration. A basic configuration could look something like this:

events {}

http {
     server {

        listen 192.168.1.111:4422;

        location / {
            proxy_pass http://192.168.2.33:80/;
        }
     }
}

your http service file:

import { Injectable } from "@angular/core";
import { ActivatedRoute, Router } from '@angular/router';
import { Http, Headers, Response, Request, RequestMethod, URLSearchParams, RequestOptions } from "@angular/http";
import {Observable} from 'rxjs/Rx';
import { Constants } from './constants';
declare var $: any;

@Injectable()
export class HttpClient {
  requestUrl: string;
  responseData: any;
  handleError: any;

  constructor(private router: Router, 
  private http: Http, 
  private constants: Constants, 
  ) {
    this.http = http;
  }

  postWithFile (url: string, postData: any, files: File[]) {

    let headers = new Headers();
    let formData:FormData = new FormData();
    formData.append('files', files[0], files[0].name);
    // For multiple files
    // for (let i = 0; i < files.length; i++) {
    //     formData.append(`files[]`, files[i], files[i].name);
    // }

    if(postData !=="" && postData !== undefined && postData !==null){
      for (var property in postData) {
          if (postData.hasOwnProperty(property)) {
              formData.append(property, postData[property]);
          }
      }
    }
    var returnReponse = new Promise((resolve, reject) => {
      this.http.post(this.constants.root_dir + url, formData, {
        headers: headers
      }).subscribe(
          res => {
            this.responseData = res.json();
            resolve(this.responseData);
          },
          error => {
            this.router.navigate(['/login']);
            reject(error);
          }
      );
    });
    return returnReponse;
  }
}

call your function (Component file):

onChange(event) {
    let file = event.srcElement.files;
    let postData = {field1:"field1", field2:"field2"}; // Put your form data variable. This is only example.
    this._service.postWithFile(this.baseUrl + "add-update",postData,file).then(result => {
        console.log(result);
    });
}

your html code:

<input type="file" class="form-control" name="documents" (change)="onChange($event)" [(ngModel)]="stock.documents" #documents="ngModel">

This should do the trick! :)

if non of the steps work from the above. my device still offline after connected through wifi. i did the following:

go to your device...

1. go to settings.

2. go to developer options.

3. Allow adb debugging in charge mode only.

4. repeat the steps as you always do . which is:

   a. connet your usb on chargemode only. b. open command write: - adb tcpip 4455 - adb connect 192.168.1.11:4455 b. disconnect usb.

now everythings work for me .

If you have an html form containing one or more fields with "required" attributes, Chrome (on last versions) will validate these fields before submitting the form and, if they are not filled, some tooltips will be shown to the users to help them getting the form submitted (I.e. "please fill out this field").

To avoid this browser built-in validation in forms you can use "novalidate" attribute on your form tag. This form won't be validated by browser:

<form id="form-id" novalidate>

    <input id="input-id" type="text" required>

    <input id="submit-button" type="submit">

</form>

In Bootstrap 3, .form-control (the class you give your inputs) has a width of 100%, which allows you to wrap them into col-lg-X divs for arrangement. Example from the docs:

<div class="row">
  <div class="col-lg-2">
    <input type="text" class="form-control" placeholder=".col-lg-2">
  </div>
  <div class="col-lg-3">
    <input type="text" class="form-control" placeholder=".col-lg-3">
  </div>
  <div class="col-lg-4">
    <input type="text" class="form-control" placeholder=".col-lg-4">
  </div>
</div>

See under Column sizing.

It's a bit different than in Bootstrap 2.3.2, but you get used to it quickly.

You can execute raw query using ActiveRecord. And I will suggest to go with SQL block

query = <<-SQL 
  SELECT * 
  FROM payment_details
  INNER JOIN projects 
          ON projects.id = payment_details.project_id
  ORDER BY payment_details.created_at DESC
SQL

result = ActiveRecord::Base.connection.execute(query)

As just formulated by grepsedawk, the answer lies in the -l option of g++, calling ld. If you look at the man page of this command, you can either do:

• g++ -l:libmagic.so.1 [...]
• or: g++ -lmagic [...] , if you have a symlink named libmagic.so in your libs path

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

Go to Files->Options->Formulas-> Calculation Options / Set Workbook calculation to Automatic

Trim C++11 implementation:

static void trim(std::string &s) {
     s.erase(s.begin(), std::find_if_not(s.begin(), s.end(), [](char c){ return std::isspace(c); }));
     s.erase(std::find_if_not(s.rbegin(), s.rend(), [](char c){ return std::isspace(c); }).base(), s.end());
}

you can add some extra information to your exception in your class and then when you catch the exception you can control your custom information to identify your exception

this.Data["mykey"]="keyvalue"; //you can add any type of data if you want 

and then you can get your value

string mystr = (string) err.Data["mykey"];

like that for more information: http://msdn.microsoft.com/en-us/library/system.exception.data.aspx

if u have optgroup inside select, u got error in DOM.

I think a best way:

$("#select option:last").after($('<option value="1">my option</option>'));

Maybe an old version of the service was not uninstalled from windows

1. uninstall the old version running this command line

   sc delete wampapache

2. Reinstall the service from wamp:

   Wamp Tray Icon -> Apache -> Service -> Install Service

It works for me, enjoy!

Just Add a primary key to the table. That's it. Problem solved.

ALTER TABLE <TABLE_NAME>
ADD CONSTRAINT <CONSTRAINT_NAME> PRIMARY KEY(<COLUMN_NAME>)

Try to change CREATE FUNCTION F_TEST(PID INT) RETURNS VARCHAR this portion to CREATE FUNCTION F_TEST(PID INT) RETURNS TEXT

and change the following line too.

DECLARE NAME_FOUND TEXT DEFAULT "";

It should work.

1. This error occurs due to importing the wrong package:
   import javax.persistence.Id;
2. And you should always give the primary key to the table, otherwise it will give an error.

If you have entities A and B without any relation between them and there is strictly 0 or 1 B for each A, you could do:

select a, (select b from B b where b.joinProperty = a.joinProperty) from A a

This would give you an Object[]{a,b} for a single result or List<Object[]{a,b}> for multiple results.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

yes there are some telltale signs for common CMSs like Drupal, Joomla, Pligg, and RoR etc .. .. ASP.NET stuff is easy to spot too .. but as the framework becomes more obscure it gets harder to deduce ..

What I usually is compare the site i am snooping with another site that I know is built using a particular tech. That sometimes works ..

Configuring this worked for me: -vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m on Eclipse Java Photon June 2018

Running Windows 10, 8 GB ram and 64 bit. You can extend -Xmx2048 -XX:MaxpermSize= 1024m to 4096m too, if your computer has good ram.Mine worked well.

DDL is Data Definition Language : Specification notation for defining the database schema. It works on Schema level.

DDL commands are:

create,drop,alter,rename

For example:

create table account (
  account_number  char(10),
 balance integer);

DML is Data Manipulation Language .It is used for accessing and manipulating the data.

DML commands are:

select,insert,delete,update,call

For example :

update account set balance = 1000 where account_number = 01;

NSString *str1 = @"Share Role Play Photo via Facebook, or Twitter for free coins per photo.";
NSString *str2 = @"Like Role Play on facebook for 50 free coins.";
NSString *str3 = @"Check out 'What's Hot' on other ways to receive free coins";


NSString *msg = [NSString stringWithFormat:@"%@\n%@\n%@", str1, str2, str3];

Open app/build.gradle file

Change buildToolsVersion to buildToolsVersion "26.0.2"

change compile 'com.android.support:appcompat to compile 'com.android.support:appcompat-v7:26.0.2'

If you are validating IP address I would suggest the following:

import socket

try:
    socket.inet_aton(addr)
    return True
except socket.error:
    return False

If you just want to check if it is in the right format then you would want to do it for all legal bases (not just base 10 numbering).

Also, are the IP address IPv4 only (and none are IPv6) then you could just look up what valid address are and use split() (to get individual components of the IP) and int() (to type-caste for comparison). A quick reference to valid IPv4 rules is here.

At the bottom, I have a general solution to replace lines in a file. But first, here is the answer to the specific question at hand. Helper function:

public static void replaceSelected(String replaceWith, String type) {
    try {
        // input the file content to the StringBuffer "input"
        BufferedReader file = new BufferedReader(new FileReader("notes.txt"));
        StringBuffer inputBuffer = new StringBuffer();
        String line;

        while ((line = file.readLine()) != null) {
            inputBuffer.append(line);
            inputBuffer.append('\n');
        }
        file.close();
        String inputStr = inputBuffer.toString();

        System.out.println(inputStr); // display the original file for debugging

        // logic to replace lines in the string (could use regex here to be generic)
        if (type.equals("0")) {
            inputStr = inputStr.replace(replaceWith + "1", replaceWith + "0"); 
        } else if (type.equals("1")) {
            inputStr = inputStr.replace(replaceWith + "0", replaceWith + "1");
        }

        // display the new file for debugging
        System.out.println("----------------------------------\n" + inputStr);

        // write the new string with the replaced line OVER the same file
        FileOutputStream fileOut = new FileOutputStream("notes.txt");
        fileOut.write(inputStr.getBytes());
        fileOut.close();

    } catch (Exception e) {
        System.out.println("Problem reading file.");
    }
}

Then call it:

public static void main(String[] args) {
    replaceSelected("Do the dishes", "1");   
}

Original Text File Content:

Do the dishes0
Feed the dog0
Cleaned my room1

Output:

Do the dishes0
Feed the dog0
Cleaned my room1
----------------------------------
Do the dishes1
Feed the dog0
Cleaned my room1

New text file content:

Do the dishes1
Feed the dog0
Cleaned my room1

And as a note, if the text file was:

Do the dishes1
Feed the dog0
Cleaned my room1

and you used the method replaceSelected("Do the dishes", "1");, it would just not change the file.

Since this question is pretty specific, I'll add a more general solution here for future readers (based on the title).

// read file one line at a time
// replace line as you read the file and store updated lines in StringBuffer
// overwrite the file with the new lines
public static void replaceLines() {
    try {
        // input the (modified) file content to the StringBuffer "input"
        BufferedReader file = new BufferedReader(new FileReader("notes.txt"));
        StringBuffer inputBuffer = new StringBuffer();
        String line;

        while ((line = file.readLine()) != null) {
            line = ... // replace the line here
            inputBuffer.append(line);
            inputBuffer.append('\n');
        }
        file.close();

        // write the new string with the replaced line OVER the same file
        FileOutputStream fileOut = new FileOutputStream("notes.txt");
        fileOut.write(inputBuffer.toString().getBytes());
        fileOut.close();

    } catch (Exception e) {
        System.out.println("Problem reading file.");
    }
}

I got the same problem. Than I realized I had a default string value for the column I was trying to alter. Removing the default value made the error go away :)

Expanding on Dominic Tancredi's awesome answer, I've rolled this into a bash package and stand-alone script. If you are already using the "Back Package Manager" called bpkg you can install the script by running:

bpkg install -g brock/node-reinstall

Or you can have a look at the script on Github at brock/node-reinstall. The script allows you to re-install node using nvm or nave, and to specify a node version as your default.

Also, for the above answers, in iOS 13 and later there is a clean way

let image = UIImage(named: "imageName")?.withTintColor(.white, renderingMode: .alwaysTemplate)

If you want to reset your table, you can do

truncate table TableName

truncate needs privileges, and you can't use it if your table has dependents (another tables that have FK of your table,

Left Click on the WAMP icon the system try -> PHP -> PHP Extensions -> Enable php_curl

If it´s in the global scope it´s better to use:

function foo()
{
    alert('foo');
}

var a = 'foo';
window[a]();

than eval(). Because eval() is evaaaaaal.

Exactly like Nosredna said 40 seconds before me that is >.<

I was having the same problem here. Found out that the problem was with an Advanced Property of the file. There is there an option with the name 'Compilation Action' (may be not with the exact words, I am translating - my VS is in Portuguese).

My Class1.cs file was there as "Content" and I just had to change it to "Compile" to make it work, and have the classes recognized by the others files in the same project.

I use java 1.8 with com.fasterxml.jackson.databind.ObjectMapper

ObjectMapper mapper = new ObjectMapper();
Integer      value = mapper.readValue(new URL("your url here"), Integer.class);

Integer.class can be also a complex type. Just for example used.

Does this do what you want?

SELECT *
FROM UserProfile
WHERE PropertydefinitionID in (40, 53)
  AND (    PropertyValue is NULL
        or PropertyValue = '' );

This guy had the magic wand we were looking for, guys.

To quote his answer:

just add "position:fixed" and it will keep it in view even if you scroll down. see it at http://jsfiddle.net/XEUbc/1/

#mydiv {
    position:fixed;
    top: 50%;
    left: 50%;
    width:30em;
    height:18em;
    margin-top: -9em; /*set to a negative number 1/2 of your height*/
    margin-left: -15em; /*set to a negative number 1/2 of your width*/
    border: 1px solid #ccc;

}

According to pip documentation at

http://pip.readthedocs.org/en/stable/user_guide/#configuration

You will need to specify the default install location within a pip.ini file, which, also according to the website above is usually located as follows

On Unix and Mac OS X the configuration file is: $HOME/.pip/pip.conf

On Windows, the configuration file is: %HOME%\pip\pip.ini

The %HOME% is located in C:\Users\Bob on windows assuming your name is Bob

On linux the $HOME directory can be located by using cd ~

You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like

[global]
target=C:\Users\Bob\Desktop

Except that you would replace C:\Users\Bob\Desktop with whatever path you desire. If you are on Linux you would replace it with something like /usr/local/your/path

After saving the command would then be

pip install pandas

However, the program you install might assume it will be installed in a certain directory and might not work as a result of being installed elsewhere.

^[+-]?\d{1,18}(\.\d{1,2})?$

accepts positive or negative decimal values.

On the Unity Editor open your project and:

1. Enable External option in Unity ? Preferences ? Packages ? Repository (only if Unity ver < 4.5)
2. Switch to Visible Meta Files in Edit ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Edit ? Project Settings ? Editor ? Asset Serialization Mode
4. Save Scene and Project from File menu.
5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

You can install miniconda (https://conda.io/miniconda.html). That's a bit more than just python 3.7 but the installation is very straightforward and simple.

curl https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O
sudo yum install bzip2
bash Miniconda3-latest-Linux-x86_64.sh

You'll have to accept the license agreement and choose some options in interactive mode (accept the defaults). I believe it can be also installed silently somehow.

I think the new hotness is to use a ScheduledThreadPoolExecutor. Like so:

private final ScheduledThreadPoolExecutor executor_ = 
        new ScheduledThreadPoolExecutor(1);
this.executor_.scheduleWithFixedDelay(new Runnable() {
@Override
public void run() {
    update();
    }
}, 0L, kPeriod, kTimeUnit);

I've a sample for multiple data with their subnode 3 list , each list has attribute and child attribute:

var list1 = {
    name: "Role A",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Write",
        id: 2,
        selected: false
    }, {
        sub: "Update",
        id: 3,
        selected: false
    }],
};
var list2 = {
    name: "Role B",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Write",
        id: 2,
        selected: false
    }],
};
var list3 = {
    name: "Role B",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Update",
        id: 3,
        selected: false
    }],
};

Add these to Array :

newArr.push(list1);
newArr.push(list2);
newArr.push(list3);
$scope.itemDisplayed = newArr;

Show them in html:

<li ng-repeat="item in itemDisplayed" class="ng-scope has-pretty-child">
    <div>
        <ul>
            <input type="checkbox" class="checkall" ng-model="item.name_selected" ng-click="toggleAll(item)" />
            <span>{{item.name}}</span>
            <div>
                <li ng-repeat="sub in item.subs" class="ng-scope has-pretty-child">
                    <input type="checkbox" kv-pretty-check="" ng-model="sub.selected" ng-change="optionToggled(item,item.subs)"><span>{{sub.sub}}</span>
                </li>
            </div>
        </ul>
    </div>
</li>

And here is the solution to check them:

$scope.toggleAll = function(item) {
    var toogleStatus = !item.name_selected;
    console.log(toogleStatus);
    angular.forEach(item, function() {
        angular.forEach(item.subs, function(sub) {
            sub.selected = toogleStatus;
        });
    });
};

$scope.optionToggled = function(item, subs) {
    item.name_selected = subs.every(function(itm) {
        return itm.selected;
    })
}

Alternatively there's the application called LiveReload...

The moral of this strangeness is:

• Use dates and times in UTC wherever possible.
• If you can not display a date or time in UTC, always indicate the time-zone.
• If you can not require an input date/time in UTC, require an explicitly indicated time-zone.

        Object AccountObject = _dbContext.Accounts
                                   .Join(_dbContext.Users, acc => acc.AccountId, usr => usr.AccountId, (acc, usr) => new { acc, usr })
                                   .Where(x => x.usr.EmailAddress == key1)
                                   .Where(x => x.usr.Hash == key2)
                                   .Select(x => new { AccountId = x.acc.AccountId, Name = x.acc.Name })
                                   .SingleOrDefault();

You can parse the output of ifconfig

http://msdn.microsoft.com/en-us/library/system.io.directory.getfiles.aspx

The System.IO namespace has loads of methods to help you with file operations. The

Directory.GetFiles() 

method returns an array of strings which represent the files in the target directory.

I found something interesting and quicker way. IE supports navigator.systemLanguage which returns "en-US" where other browsers return undefined.

<script>
    var lang = navigator.systemLanguage;
    if (lang!='en-US'){document.write("Well, this is not internet explorer");}
    else{document.write("This is internet explorer");}
</script>

I found jszip quite useful. I've used so far only for reading, but they have create/edit capabilities as well.

Code wise it looks something like this

var new_zip = new JSZip();
new_zip.load(file);
new_zip.files["doc.xml"].asText() // this give you the text in the file

One thing I noticed is that it seems the file has to be in binary stream format (read using the .readAsArrayBuffer of FileReader(), otherwise I was getting errors saying I might have a corrupt zip file

Edit: Note from the 2.x to 3.0.0 upgrade guide:

The load() method and the constructor with data (new JSZip(data)) have been replaced by loadAsync().

Use PHP's $_POST or $_GET superglobals to retrieve the value of the input tag via the name of the HTML tag.

For Example, change the method in your form and then echo out the value by the name of the input:

Using $_GET method:

<form name="form" action="" method="get">
  <input type="text" name="subject" id="subject" value="Car Loan">
</form>

To show the value:

<?php echo $_GET['subject']; ?>

Using $_POST method:

<form name="form" action="" method="post">
  <input type="text" name="subject" id="subject" value="Car Loan">
</form>

To show the value:

<?php echo $_POST['subject']; ?>

Dot grammar maybe more swift!

@(intValueDemo).stringValue 

for example

int intValueDemo  = 1;
//or
NSInteger intValueDemo = 1;

//So you can use dot grammar 
NSLog(@"%@",@(intValueDemo).stringValue);

You have a truncated array representation. Let's look at a full example:

>>> a = np.zeros((2, 3, 4))
>>> a
array([[[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]],

       [[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]]])

Arrays in NumPy are printed as the word array followed by structure, similar to embedded Python lists. Let's create a similar list:

>>> l = [[[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]],

          [[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]]]

>>> l
[[[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]], 
 [[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]]]

The first level of this compound list l has exactly 2 elements, just as the first dimension of the array a (# of rows). Each of these elements is itself a list with 3 elements, which is equal to the second dimension of a (# of columns). Finally, the most nested lists have 4 elements each, same as the third dimension of a (depth/# of colors).

So you've got exactly the same structure (in terms of dimensions) as in Matlab, just printed in another way.

Some caveats:

1. Matlab stores data column by column ("Fortran order"), while NumPy by default stores them row by row ("C order"). This doesn't affect indexing, but may affect performance. For example, in Matlab efficient loop will be over columns (e.g. for n = 1:10 a(:, n) end), while in NumPy it's preferable to iterate over rows (e.g. for n in range(10): a[n, :] -- note n in the first position, not the last).

2. If you work with colored images in OpenCV, remember that:

   2.1. It stores images in BGR format and not RGB, like most Python libraries do.

   2.2. Most functions work on image coordinates (x, y), which are opposite to matrix coordinates (i, j).

Step:1

git remote rm origin

Step:2

git remote add origin enter_your_repository_url

Example:

git remote add origin https://github.com/my_username/repository_name.git

reader.IsDbNull(ColumnIndex) works as many answers says.

And I want to mention if you working with column names, just comparing types may be more comfortable.

if(reader["TeacherImage"].GetType() == typeof(DBNull)) { //logic }

Here is a step by step video of uploading eclipse projects to github

https://www.youtube.com/watch?v=BH4OqYHoHC0

Adding the Steps here.

1. Right click on your eclipse project -> Team -> Share project

2. Choose git from the list shown; check the box asking create or use repository -> click on create repository and click finish. - This will create a local git repo. (Assuming you already have git installed )

3. Right click on project -> Team -> Commit - Select only the files you want to commit and click on Commit. - Now the files are committed to your local repo.

4. Go to git repositories view in eclipse ( or Team -> Show in repositories View)

5. Expand the git repo of your project and Right click on Remotes -> Create Remote

6. Remote name will appear as origin, select 'Configure Push' Option and click ok

7. In the next dialog, click on change next to URI textbox and give your git url, username, password and click on 'Save and Push'. This configures git Push.

8. For configuring Fetch, go to Git Repositories -> Remote -> Configure Fetch -> Add -> Master Branch -> Next -> Finish -> Save and Fetch

9. For configuring Master Branch, Branch -> Local -> Master Branch -> Right click and configure branch -> Remote: origin and Upstream Branch : refs/heads/master -> click ok

On refreshing your repo, you will be able to see the files you committed and you can do push and pull from repo.

I tried using the solution By @davy-c but had an Exception "System.FormatException: 'Input string was not in a correct format.'", this was due to there still being text past the line number, I modified the code he posted and came up with:

int line = Convert.ToInt32(objErr.ToString().Substring(objErr.ToString().IndexOf("line")).Substring(0, objErr.ToString().Substring(objErr.ToString().IndexOf("line")).ToString().IndexOf("\r\n")).Replace("line ", ""));

This works for me in VS2017 C#.

I could not get this working with the accepted answer, mainly because I did not know where to enter that code. I looked everywhere for some explanation of the URL Rewrite tool that made sense, but could not find any. I ended up using the HTTP Redirect tool in IIS.

1. Choose your site
2. Click HTTP Redirect in the IIS section (Make sure the Role Service is installed)
3. Check "Redirect requests to this destination"
4. Enter where you want to redirect. In your case "wwww.mysite.com/menu_1/MainScreen.aspx"
5. In Redirect Behavior, I found I had to check "Only redirect requests to content in this directory (not subdirectories), or it would go into a loop. See what works for you.

Hope this helps.

The backquote operator will also allow you to run python scripts using similar syntax to above

In a python file called python.py:

hello = "hello"
world = "world"
print hello + " " + world

In a php file called python.php:

$python = `python python.py`;
echo $python;

Using Math.Round():

int percentComplete = (int)Math.Round((double)(100 * complete) / total);

or manually rounding:

int percentComplete = (int)(0.5f + ((100f * complete) / total));

What is the right approach for doing this?

There are a lot of "right" approaches, you just have decide which one best suites your needs. It appears as though you're misunderstanding how to use node_modules...

If you're familiar with NuGet you should think of npm as its client-side counterpart. Where the node_modules directory is like the bin directory for NuGet. The idea is that this directory is just a common location for storing packages, in my opinion it is better to take a dependency on the packages you need as you have done in the package.json. Then use a task runner like Gulp for example to copy the files you need into your desired wwwroot location.

I wrote a blog post about this back in January that details npm, Gulp and a whole bunch of other details that are still relevant today. Additionally, someone called attention to my SO question I asked and ultimately answered myself here, which is probably helpful.

I created a Gist that shows the gulpfile.js as an example.

In your Startup.cs it is still important to use static files:

app.UseStaticFiles();

This will ensure that your application can access what it needs.

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

pandas.io.parsers.read_csv documentation

You do not have to install something.

parseInt(req.params.year, 10);

should work properly.

console.log(typeof parseInt(req.params.year)); // returns 'number'

What is your output, if you use parseInt? is it still a string?

When writing queries with our server LIKE or INSTR (or CHARINDEX in T-SQL) takes too long, so we use LEFT like in the following structure:

select *
from little
left join big
on left( big.key, len(little.key) ) = little.key

I understand that might only work with varying endings to the query, unlike other suggestions with '%' + b + '%', but is enough and much faster if you only need b+'%'.

Another way to optimize it for speed (but not memory) is to create a column in "little" that is "len(little.key)" as "lenkey" and user that instead in the query above.

Since none of the previous answers included set it took me a bit to figure out how to do it in Windows without altering the php.ini, but here's what worked for me:

set COMPOSER_MEMORY_LIMIT=-1
composer require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle

From here download this video so we have the same video file for the test. Make sure to have that mp4 file in the same directory of your python code. Then also make sure to run the python interpreter from the same directory.

Then modify the code, ditch waitKey that's wasting time also without a window it cannot capture the keyboard events. Also we print the success value to make sure it's reading the frames successfully.

import cv2
vidcap = cv2.VideoCapture('big_buck_bunny_720p_5mb.mp4')
success,image = vidcap.read()
count = 0
while success:
  cv2.imwrite("frame%d.jpg" % count, image)     # save frame as JPEG file      
  success,image = vidcap.read()
  print('Read a new frame: ', success)
  count += 1

How does that go?

This code works for me:

public static Drawable changeBackArrowColor(Context context, int color) {
    String resName;
    int res;

    resName = Build.VERSION.SDK_INT >= 23 ? "abc_ic_ab_back_material" : "abc_ic_ab_back_mtrl_am_alpha";
    res = context.getResources().getIdentifier(resName, "drawable", context.getPackageName());

    final Drawable upArrow = context.getResources().getDrawable(res);
    upArrow.setColorFilter(color, PorterDuff.Mode.SRC_ATOP);

    return upArrow;
}

...

getSupportActionBar().setHomeAsUpIndicator(changeBackArrowColor(this, Color.rgb(50, 50, 50)));               
supportInvalidateOptionsMenu();

Also, if you want to change the toolbar text color:

Spannable spannableString = new SpannableString(t);
spannableString.setSpan(new ForegroundColorSpan(Color.rgb(50, 50, 50)), 0, t.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
toolbar.setText(spannableString);

Working from API 19 through 25.

If you just need to search for one string within another, use the index function (or rindex if you want to start scanning from the end of the string):

if (index($string, $substring) != -1) {
   print "'$string' contains '$substring'\n";
}

To search a string for a pattern match, use the match operator m//:

if ($string =~ m/pattern/) {
    print "'$string' matches the pattern\n";       
}

Define what GetData is. At the moment it is not defined.

Function getData(currentWorksheet as Worksheet, dataStartRow as Integer, dataEndRow as Integer, DataStartCol as Integer, dataEndCol as Integer) as variant

The other solutions are good. If these are your goals:

1. No truncation of columns,
2. No loss of rows,
3. Fast and
4. Efficient

These two lines are useful ...

    df.persist
    df.show(df.count, false) // in Scala or 'False' in Python

By persisting, the 2 executor actions, count and show, are faster & more efficient when using persist or cache to maintain the interim underlying dataframe structure within the executors. See more about persist and cache.

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

There are two ways to go about this. You can either use the IDE to generate a WSDL, or you can do it via the command line.

1. To create it via the IDE:

In the solution explorer pane, right click on the project that you would like to add the Service to:

Then, you can enter the path to your service WSDL and hit go:

2. To create it via the command line:

Open a VS 2010 Command Prompt (Programs -> Visual Studio 2010 -> Visual Studio Tools)
Then execute:

WSDL /verbose C:\path\to\wsdl

WSDL.exe will then output a .cs file for your consumption.

If you have other dependencies that you received with the file, such as xsd's, add those to the argument list:

WSDL /verbose C:\path\to\wsdl C:\path\to\some\xsd C:\path\to\some\xsd

If you need VB output, use /language:VB in addition to the /verbose.

Try this runner I wrote. It could be helpful.

        System.arraycopy(args, 1, newArgs, 0, newArgs.length);
        method.invoke(null, new Object[]{newArgs});
    }

}

I feel my solution is a very clean and nice solution:

public static T? NullableParse<T>(string s) where T : struct
{
    try
    {
        return (T)typeof(T).GetMethod("Parse", new[] {typeof(string)}).Invoke(null, new[] { s });
    }
    catch (Exception)
    {
        return null;
    }
}

This is of course a generic solution which only require that the generics argument has a static method "Parse(string)". This works for numbers, boolean, DateTime, etc.

As it has been noted here, a better way of achieving this in C++ might be using namespaces. But since no one has mentioned the final keyword here, I'm posting what a direct equivalent of static class from C# would look like in C++11 or later:

class BitParser final
{
public:
  BitParser() = delete;

  static bool GetBitAt(int buffer, int pos);
};

bool BitParser::GetBitAt(int buffer, int pos)
{
  // your code
}

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

example about this here Initialising jQuery plugin (RoyalSlider) in Angular JS

• To convert the epoch(Unix-Time) to regular time like for the below timestamp

  Ex: 1517577336206

• First convert the value with the following function like below

  =LEFT(A1,10) & "." & RIGHT(A1,3)

• The output will be like below

  Ex: 1517577336.206

• Now Add the formula like below

  =(((B1/60)/60)/24)+DATE(1970,1,1)

• Now format the cell like below or required format(Custom format)

  m/d/yyyy h:mm:ss.000

Now example time comes like

2/2/2018 13:15:36.206

The three zeros are for milliseconds

Try set-executionpolicy "Policyname" -force switch and the warnings pop-up should not come.

There is a difference between

• the content of a dataframe cell (a binary value) and
• its presentation (displaying it) for us, humans.

So the question is: How to reach the appropriate presentation of my datas without changing the data / data types themselves?

Here is the answer:

• If you use the Jupyter notebook for displaying your dataframe, or
• if you want to reach a presentation in the form of an HTML file (even with many prepared superfluous id and class attributes for further CSS styling — you may or you may not use them),

use styling. Styling don't change data / data types of columns of your dataframe.

Now I show you how to reach it in the Jupyter notebook — for a presentation in the form of HTML file see the note near the end of the question.

I will suppose that your column DOB already has the type datetime64 (you shown that you know how to reach it). I prepared a simple dataframe (with only one column) to show you some basic styling:

• Not styled:

     df
  

          DOB
0  2019-07-03
1  2019-08-03
2  2019-09-03
3  2019-10-03

• Styling it as mm/dd/yyyy:

     df.style.format({"DOB": lambda t: t.strftime("%m/%d/%Y")})
  

          DOB
0  07/03/2019
1  08/03/2019
2  09/03/2019
3  10/03/2019

• Styling it as dd-mm-yyyy:

     df.style.format({"DOB": lambda t: t.strftime("%d-%m-%Y")}) 
  

          DOB
0  03-07-2019
1  03-08-2019
2  03-09-2019
3  03-10-2019

Be careful!
The returning object is NOT a dataframe — it is an object of the class Styler, so don't assign it back to df:

Don´t do this:

df = df.style.format({"DOB": lambda t: t.strftime("%m/%d/%Y")})    # Don´t do this!

(Every dataframe has its Styler object accessible by its .style property, and we changed this df.style object, not the dataframe itself.)

Questions and Answers:

• Q: Why your Styler object (or an expression returning it) used as the last command in a Jupyter notebook cell displays your (styled) table, and not the Styler object itself?

• A: Because every Styler object has a callback method ._repr_html_() which returns an HTML code for rendering your dataframe (as a nice HTML table).

  Jupyter Notebook IDE calls this method automatically to render objects which have it.

Note:

You don't need the Jupyter notebook for styling (i.e. for nice outputting a dataframe without changing its data / data types).

A Styler object has a method render(), too, if you want to obtain a string with the HTML code (e.g. for publishing your formatted dataframe to the Web, or simply present your table in the HTML format):

df_styler = df.style.format({"DOB": lambda t: t.strftime("%m/%d/%Y")})
HTML_string = df_styler.render()

Just put your globals in the file you are importing.

Maybe you could take a look at JFileChooser, which allow you to use native dialogs in one line of code.

If you need the full url (for instance to send by email) consider using one of the following built-in methods:

With this you create the route to use to build the url:

Url.RouteUrl("OpinionByCompany", new RouteValueDictionary(new{cid=newop.CompanyID,oid=newop.ID}), HttpContext.Request.Url.Scheme, HttpContext.Request.Url.Authority)

Here the url is built after the route engine determine the correct one:

Url.Action("Detail","Opinion",new RouteValueDictionary(new{cid=newop.CompanyID,oid=newop.ID}),HttpContext.Request.Url.Scheme, HttpContext.Request.Url.Authority)

In both methods, the last 2 parameters specifies the protocol and hostname.

Regards.

Just in case it helps someone, since these questions (and answers) helped me really much; I decided to create an alias that runs these 4 commands in a row:

Just add the following line to your ~/.bashrc file (modify the main keyword accordingly to the name of your .tex and .bib files)

alias texbib = 'pdflatex main.tex && bibtex main && pdflatex main.tex && pdflatex main.tex'

And now, by just executing the texbib command (alias), all these commands will be executed sequentially.

Because you are passing three arguments to a four arguments method. Also, you are not using the passed closure.

If you want to specify the operations to be made on top of the source contents, then use a closure. It would be something like this:

def copyAndReplaceText(source, dest, closure){
    dest.write(closure( source.text ))
}

// And you can keep your usage as:
copyAndReplaceText(source, dest){
    it.replaceAll('Visa', 'Passport!!!!')
}

If you will always swap strings, pass both, as your method signature already states:

def copyAndReplaceText(source, dest, targetText, replaceText){
    dest.write(source.text.replaceAll(targetText, replaceText))
}

copyAndReplaceText(source, dest, 'Visa', 'Passport!!!!')

It is not a good idea to use regex for HTML/XML parsing...

However, if you want to do it anyway, search for regex pattern

<primaryAddress>[\s\S]*?<\/primaryAddress>

and replace it with empty string...

There are two ways, one is defined in html when you define table headers

<thead>
  <th data-orderable="false"></th>
</thead>

Another way is using javascript, for example, you have table

<table id="datatables">
    <thead>
        <tr>
            <th class="testid input">test id</th>
            <th class="testname input">test name</th>
    </thead>
</table>

then,

$(document).ready(function() {
    $('#datatables').DataTable( {
        "columnDefs": [ {
            "targets": [ 0], // 0 indicates the first column you define in <thead>
            "searchable": false
        }
        , {
            // you can also use name to get the target column
            "targets": 'testid', // name is the class you define in <th>
            "searchable": false
        }
        ]
    }
    );
}
);

One use of pointers (I won't mention things already covered in other people's posts) is to access memory that you haven't allocated. This isn't useful much for PC programming, but it's used in embedded programming to access memory mapped hardware devices.

Back in the old days of DOS, you used to be able to access the video card's video memory directly by declaring a pointer to:

unsigned char *pVideoMemory = (unsigned char *)0xA0000000;

Many embedded devices still use this technique.

In Swift:

Add this to the controller

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.setHidesBackButton(true, animated: false)
}

[If you want some ready-to-use code, please scroll to my "Edit3" (after the cut). The rest is here for posterity.]

To flesh out Dustman's idea:

List<String> list = new ArrayList<String>(Arrays.asList(array));
list.removeAll(Arrays.asList("a"));
array = list.toArray(array);

Edit: I'm now using Arrays.asList instead of Collections.singleton: singleton is limited to one entry, whereas the asList approach allows you to add other strings to filter out later: Arrays.asList("a", "b", "c").

Edit2: The above approach retains the same array (so the array is still the same length); the element after the last is set to null. If you want a new array sized exactly as required, use this instead:

array = list.toArray(new String[0]);

Edit3: If you use this code on a frequent basis in the same class, you may wish to consider adding this to your class:

private static final String[] EMPTY_STRING_ARRAY = new String[0];

Then the function becomes:

List<String> list = new ArrayList<>();
Collections.addAll(list, array);
list.removeAll(Arrays.asList("a"));
array = list.toArray(EMPTY_STRING_ARRAY);

This will then stop littering your heap with useless empty string arrays that would otherwise be newed each time your function is called.

cynicalman's suggestion (see comments) will also help with the heap littering, and for fairness I should mention it:

array = list.toArray(new String[list.size()]);

I prefer my approach, because it may be easier to get the explicit size wrong (e.g., calling size() on the wrong list).

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

What is your PHP version? Extension "Mysql" was deprecated in PHP 5.5.0. Use extension Mysqli (like mysqli_query).

Try this:

CREATE TABLE SCHEMA.NEW_TB LIKE SCHEMA.OLD_TB;
INSERT INTO SCHEMA.NEW_TB (SELECT * FROM SCHEMA.OLD_TB);

Options that are not copied include:

• Check constraints
• Column default values
• Column comments
• Foreign keys
• Logged and compact option on BLOB columns
• Distinct types

I was facing the same issue and i found out that I was having two terminals in visual studio code, On first terminal it was already running my flutter project and on the other terminal I was running different solutions shared in this thread. Due to this reason no solution was working for me. So there are two ways you can solve this problem. 1- Restart visual studio code (it will automatically close the terminals) 2- Stop the terminal in which flutter project is already running and then run flutter clean command.

naturalWidth and naturalHeight

var img = document.createElement("img");
img.onload = function (event)
{
    console.log("natural:", img.naturalWidth, img.naturalHeight);
    console.log("width,height:", img.width, img.height);
    console.log("offsetW,offsetH:", img.offsetWidth, img.offsetHeight);
}
img.src = "image.jpg";
document.body.appendChild(img);

// css for tests
img { width:50%;height:50%; }

Just a slightly cleaned up way of doing this. This is no more or less performant than ATOzTOA's answer, but there's no reason to do two separate with statements.

with open(path_1, 'a') as file_1, open(path_2, 'r') as file_2:
    for line in file_2:
        if 'tests/file/myword' in line:
            file_1.write(line)

If you want happen to be using LESS it can be achieved like so:

li {
    .glyphicon-ok();

    &:before {            
        .glyphicon();            
        margin-left:-25px;
       float:left;
    }
}

Following answer can help in this and other similar situations like synchronous AJAX call -

Working example

waitForMe().then(function(intentsArr){
  console.log('Finally, I can execute!!!');
},
function(err){
  console.log('This is error message.');
})

function waitForMe(){
    // Returns promise
    console.log('Inside waitForMe');
    return new Promise(function(resolve, reject){
        if(true){ // Try changing to 'false'
            setTimeout(function(){
                console.log('waitForMe\'s function succeeded');
                resolve();
            }, 2500);
        }
        else{
            setTimeout(function(){
                console.log('waitForMe\'s else block failed');
                resolve();
            }, 2500);
        }
    });
}

You have more than one form tags with runat="server" on your template, most probably you have one in your master page, remove one on your aspx page, it is not needed if already have form in master page file which is surrounding your content place holders.

Try to remove that tag:

<form id="formID" runat="server">

and of course closing tag:

</form>

The use of ui-sref-active directive that worked for me was:

<li ui-sref-active="{'active': 'admin'}">
    <a ui-sref="admin.users">Administration Panel</a>
</li>

as found here under the comment labeled "tgrant59 commented on May 31, 2016".

I am using angular-ui-router v0.3.1.

These are positional arguments of the script.

Executing

./script.sh Hello World

Will make

$0 = ./script.sh
$1 = Hello
$2 = World

Note

If you execute ./script.sh, $0 will give output ./script.sh but if you execute it with bash script.sh it will give output script.sh.

To parallelize a simple for loop, joblib brings a lot of value to raw use of multiprocessing. Not only the short syntax, but also things like transparent bunching of iterations when they are very fast (to remove the overhead) or capturing of the traceback of the child process, to have better error reporting.

Disclaimer: I am the original author of joblib.

The $ symbol simply invokes the jQuery library's selector functionality. So $("#Text") returns the jQuery object for the Text div which can then be modified.

This turns out to be a pretty deep area of theory, but the basic outline is simple.

Essentially, a hash function is just a function that takes things from one space (say strings of arbitrary length) and maps them to a space useful for indexing (unsigned integers, say).

If you only have a small space of things to hash, you might get away with just interpreting those things as integers, and you're done (e.g. 4 byte strings)

Usually, though, you've got a much larger space. If the space of things you allow as keys is bigger than the space of things you are using to index (your uint32's or whatever) then you can't possibly have a unique value for each one. When two or more things hash to the same result, you'll have to handle the redundancy in an appropriate way (this is usually referred to as a collision, and how you handle it or don't will depend a bit on what you are using the hash for).

This implies you want it to be unlikely to have the same result, and you probably also would really like the hash function to be fast.

Balancing these two properties (and a few others) has kept many people busy!

In practice you usually should be able to find a function that is known to work well for your application and use that.

Now to make this work as a hashtable: Imagine you didn't care about memory usage. Then you can create an array as long as your indexing set (all uint32's, for example). As you add something to the table, you hash it's key and look at the array at that index. If there is nothing there, you put your value there. If there is already something there, you add this new entry to a list of things at that address, along with enough information (your original key, or something clever) to find which entry actually belongs to which key.

So as you go a long, every entry in your hashtable (the array) is either empty, or contains one entry, or a list of entries. Retrieving is a simple as indexing into the array, and either returning the value, or walking the list of values and returning the right one.

Of course in practice you typically can't do this, it wastes too much memory. So you do everything based on a sparse array (where the only entries are the ones you actually use, everything else is implicitly null).

There are lots of schemes and tricks to make this work better, but that's the basics.

You can always create an ArrayList of Objects. But it will not be very useful to you. Suppose you have created the Arraylist like this:

List<Object> myList = new ArrayList<Object>();

and add objects to this list like this:

myList.add(new Integer("5"));

myList.add("object");

myList.add(new Object());

You won't face any problem while adding and retrieving the object but it won't be very useful. You have to remember at what location each type of object is it in order to use it. In this case after retrieving, all you can do is calling the methods of Object on them.

In my case, I want to add a column to a Primary key (column4). I used this script to add column4

ALTER TABLE TableA
DROP CONSTRAINT [PK_TableA]

ALTER TABLE TableA
ADD CONSTRAINT [PK_TableA] PRIMARY KEY (
    [column1] ASC,
    [column2] ASC, 
    [column3] ASC,
    [column4] ASC
)

        }
        array.put(jsonObject);
        return array.toString();
    }

}

From your above needs, you will need to use both Python (to export pandas data frame) and VBA (to delete existing worksheet content and copy/paste external data).

With Python: use the to_csv or to_excel methods. I recommend the to_csv method which performs better with larger datasets.

# DF TO EXCEL
from pandas import ExcelWriter

writer = ExcelWriter('PythonExport.xlsx')
yourdf.to_excel(writer,'Sheet5')
writer.save()

# DF TO CSV
yourdf.to_csv('PythonExport.csv', sep=',')

With VBA: copy and paste source to destination ranges.

Fortunately, in VBA you can call Python scripts using Shell (assuming your OS is Windows).

Sub DataFrameImport()
  'RUN PYTHON TO EXPORT DATA FRAME
  Shell "C:\pathTo\python.exe fullpathOfPythonScript.py", vbNormalFocus

  'CLEAR EXISTING CONTENT
  ThisWorkbook.Worksheets(5).Cells.Clear

  'COPY AND PASTE TO WORKBOOK
  Workbooks("PythonExport").Worksheets(1).Cells.Copy
  ThisWorkbook.Worksheets(5).Range("A1").Select
  ThisWorkbook.Worksheets(5).Paste
End Sub

Alternatively, you can do vice versa: run a macro (ClearExistingContent) with Python. Be sure your Excel file is a macro-enabled (.xlsm) one with a saved macro to delete Sheet 5 content only. Note: macros cannot be saved with csv files.

import os
import win32com.client
from pandas import ExcelWriter

if os.path.exists("C:\Full Location\To\excelsheet.xlsm"):
  xlApp=win32com.client.Dispatch("Excel.Application")
  wb = xlApp.Workbooks.Open(Filename="C:\Full Location\To\excelsheet.xlsm")

  # MACRO TO CLEAR SHEET 5 CONTENT
  xlApp.Run("ClearExistingContent")
  wb.Save() 
  xlApp.Quit()
  del xl

  # WRITE IN DATA FRAME TO SHEET 5
  writer = ExcelWriter('C:\Full Location\To\excelsheet.xlsm')
  yourdf.to_excel(writer,'Sheet5')
  writer.save() 

Escaped percent sign is double percent (%%):

System.out.printf("2 out of 10 is %d%%", 20);

You could use python-benedict, it's a dict subclass.

Installation: pip install python-benedict

from benedict import benedict

dict_you_want = benedict(your_dict).subset(keys=['firstname', 'lastname', 'email'])

It's open-source on GitHub: https://github.com/fabiocaccamo/python-benedict

^{Disclaimer: I'm the author of this library.}

Is your application running as a 64 or 32bit process? You can check this in the task manager.

It could be, it is running as 32bit, even though the entire system is running on 64bit.

If 32bit, a third party library could be causing this. But first make sure your application is compiling for "Any CPU", as stated in the comments.

Without examples of the dataset of staging this is a shot in the dark, but have you tried something like this?

update PRODUCTION p,
       staging s
set p.name = s.name  
    p.count = s.count
where p.id = s.id

This would work assuming the id column matches on both tables.

You can go to Design mode and select "Fix" at the bottom of the warning. Then a pop up will appear (seems like it's going to register the new string) and voila, the error is fixed.

For any T object you can do:

return Request.CreateResponse<T>(HttpStatusCode.OK, Tobject);

I know it's not an answer to the exact question asked, but I found this question looking to diff a file in a branch and a local uncommitted file and I figured I would share

Syntax:

git diff <commit-ish>:./ -- <path>

Examples:

git diff origin/master:./ -- README.md
git diff HEAD^:./ -- README.md

(Thanks Eric Boehs for a way to not have to type the filename twice)

Another way:

sprintf("%s you can add other static strings here %s",string1,string2)

It sometimes useful than paste() function. %s denotes the place where the subjective strings will be included.

Note that this will come in handy as you try to build a path:

sprintf("/%s", paste("this", "is", "a", "path", sep="/"))

output

/this/is/a/path

The previous posters made a little mistake. The accept attribute is only a display filter. It will not validate your entry before submitting.

This attribute forces the file dialog to display the required mime type only. But the user can override that filter. He can choose . and see all the files in the current directory. By doing so, he can select any file with any extension, and submit the form.

So, to answer to the original poster, NO. You cannot restrict the input file to one particular extension by using HTML.

But you can use javascript to test the filename that has been chosen, just before submitting. Just insert an onclick attribute on your submit button and call the code that will test the input file value. If the extension is forbidden, you'll have to return false to invalidate the form. You may even use a jQuery custom validator and so on, to validate the form.

Finally, you'll have to test the extension on the server side too. Same problem about the maximum allowed file size.

Another clean option that I have found useful is pandas.DataFrame.mask which will "replace values where the condition is true."

Create the DataFrame:

In [2]: import pandas as pd

In [3]: df = pd.DataFrame({'a': [0, -1, 2], 'b': [-3, 2, 1]})

In [4]: df
Out[4]: 
   a  b
0  0 -3
1 -1  2
2  2  1

Replace negative numbers with 0:

In [5]: df.mask(df < 0, 0)
Out[5]: 
   a  b
0  0  0
1  0  2
2  2  1

Or, replace negative numbers with NaN, which I frequently need:

In [7]: df.mask(df < 0)
Out[7]: 
     a    b
0  0.0  NaN
1  NaN  2.0
2  2.0  1.0

Another option you can go with here:

df.loc["Total", "MyColumn"] = df.MyColumn.sum()

#         X  MyColumn      Y       Z
#0        A     84.0    13.0    69.0
#1        B     76.0    77.0   127.0
#2        C     28.0    69.0    16.0
#3        D     28.0    28.0    31.0
#4        E     19.0    20.0    85.0
#5        F     84.0   193.0    70.0
#Total  NaN    319.0     NaN     NaN

You can also use append() method:

df.append(pd.DataFrame(df.MyColumn.sum(), index = ["Total"], columns=["MyColumn"]))

Update:

In case you need to append sum for all numeric columns, you can do one of the followings:

Use append to do this in a functional manner (doesn't change the original data frame):

# select numeric columns and calculate the sums
sums = df.select_dtypes(pd.np.number).sum().rename('total')

# append sums to the data frame
df.append(sums)
#         X  MyColumn      Y      Z
#0        A      84.0   13.0   69.0
#1        B      76.0   77.0  127.0
#2        C      28.0   69.0   16.0
#3        D      28.0   28.0   31.0
#4        E      19.0   20.0   85.0
#5        F      84.0  193.0   70.0
#total  NaN     319.0  400.0  398.0

Use loc to mutate data frame in place:

df.loc['total'] = df.select_dtypes(pd.np.number).sum()
df
#         X  MyColumn      Y      Z
#0        A      84.0   13.0   69.0
#1        B      76.0   77.0  127.0
#2        C      28.0   69.0   16.0
#3        D      28.0   28.0   31.0
#4        E      19.0   20.0   85.0
#5        F      84.0  193.0   70.0
#total  NaN     638.0  800.0  796.0

The only easy way to do this is to use snprintf to print to a buffer that's long enough to hold the entire, exact value, then truncate it as a string. Something like:

char buf[2*(DBL_MANT_DIG + DBL_MAX_EXP)];
snprintf(buf, sizeof buf, "%.*f", (int)sizeof buf, x);
char *p = strchr(buf, '.'); // beware locale-specific radix char, though!
p[2+1] = 0;
puts(buf);

""" regex for finding valid ip address """

import re


IPV4 = re.fullmatch('([0-2][0-5]{2}|\d{2}|\d).([0-2][0-5]{2}|\d{2}|\d).([0-2][0-5]{2}|\d{2}|\d).([0-2][0-5]{2}|\d{2}|\d)', '100.1.1.2')

if IPV4:
    print ("Valid IP address")

else:
    print("Invalid IP address")

A solution could be to use a local file which retrieves the remote content

remoteInclude.php

<?php
$url = $_GET['url'];
$contents = file_get_contents($url);
echo $contents;

The HTML

<iframe frameborder="1" id="frametest" src="/remoteInclude.php?url=REMOTE_URL_HERE"></iframe>
<script>
    $("#frametest").load(function (){       
    var contents =$("#frametest").contents();
});

Let's start with the uncomfortable truth: GWT compiler performance is really lousy. You can use some hacks here and there, but you're not going to get significantly better performance.

A nice performance hack you can do is to compile for only specific browsers, by inserting the following line in your gwt.xml:

<define-property name="user.agent" values="ie6,gecko,gecko1_8"></define-property>

or in gwt 2.x syntax, and for one browser only:

<set-property name="user.agent" value="gecko1_8"/>

This, for example, will compile your application for IE and FF only. If you know you are using only a specific browser for testing, you can use this little hack.

Another option: if you are using several locales, and again using only one for testing, you can comment them all out so that GWT will use the default locale, this shaves off some additional overhead from compile time.

Bottom line: you're not going to get order-of-magnitude increase in compiler performance, but taking several relaxations, you can shave off a few minutes here and there.

Visual Studio 2017 Team Explorer

According to https://blogs.msdn.microsoft.com/bharry/2017/04/05/team-explorer-for-tfs-2017/ you can now download it separately from Visual Studio via this link:

As the others have said, there is no difference in the compiled code (IL) when you use either of the following:

var x1 = new object();
object x2 = new object;

I suppose Resharper warns you because it is [in my opinion] easier to read the first example than the second. Besides, what's the need to repeat the name of the type twice?

Consider the following and you'll get what I mean:

KeyValuePair<string, KeyValuePair<string, int>> y1 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

It's way easier to read this instead:

var y2 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

You'll need to join twice:

SELECT home.*, away.*, g.network, g.date_start 
FROM game AS g
INNER JOIN team AS home
  ON home.importid = g.home
INNER JOIN team AS away
  ON away.importid = g.away
ORDER BY g.date_start DESC 
LIMIT 7

I aso find this extremely confusing. as @EricMartinez points out Renderer2 listen() returns the function to remove the listener:

ƒ () { return element.removeEventListener(eventName, /** @type {?} */ (handler), false); }

If i´m adding a listener

this.listenToClick = this.renderer.listen('document', 'click', (evt) => {
    alert('Clicking the document');
})

I´d expect my function to execute what i intended, not the total opposite which is remove the listener.

// I´d expect an alert('Clicking the document'); 
this.listenToClick();
// what you actually get is removing the listener, so nothing...

In the given scenario, It´d actually make to more sense to name it like:

// Add listeners
let unlistenGlobal = this.renderer.listen('document', 'click', (evt) => {
    console.log('Clicking the document', evt);
})

let removeSimple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
    console.log('Clicking the button', evt);
});

There must be a good reason for this but in my opinion it´s very misleading and not intuitive.

Simple answer :

class MyClass {}

const instance = new MyClass();

console.log(instance.constructor.name); // MyClass
console.log(MyClass.name);              // MyClass

However: beware that the name will likely be different when using minified code.

This works and it is a lot easier to toggle that the methods above:

use inline: onended="if($(this).attr('data-loop')){ this.currentTime = 0; this.play(); }"

Turn the looping on by $(audio_element).attr('data-loop','1'); Turn the looping off by $(audio_element).removeAttr('data-loop');

If you mean the screen where you have that interpreter prompt >>> you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do

import os
os.system('cls')  # on windows

or

os.system('clear')  # on linux / os x

You can create a variable with an application scope
