yourSelect.setAttribute( "onchange", "yourFunction()" );

Use a negative lookahead and a negative lookbehind:

> s = "one two 3.4 5,6 seven.eight nine,ten"
> parts = re.split('\s|(?<!\d)[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten']

In other words, you always split by \s (whitespace), and only split by commas and periods if they are not followed (?!\d) or preceded (?<!\d) by a digit.

DEMO.

EDIT: As per @verdesmarald comment, you may want to use the following instead:

> s = "one two 3.4 5,6 seven.eight nine,ten,1.2,a,5"
> print re.split('\s|(?<!\d)[,.]|[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten', '1.2', 'a', '5']

This will split "1.2,a,5" into ["1.2", "a", "5"].

DEMO.

The section tag provides a more semantic syntax for html. div is a generic tag for a section. When you use section tag for appropriate content, it can be used for search engine optimization also. section tag also makes it easy for html parsing. for more info, refer. http://blog.whatwg.org/is-not-just-a-semantic

I remember the StaticSelectedStyle-CssClass attribute used to work in ASP.NET 2.0. And in .NET 4.0 if you change the Menu control's RenderingMode attribute "Table" (thus making it render the menu as s and sub-s like it did back '05) it will at least write your specified StaticSelectedStyle-CssClass into the proper html element.

That may be enough for you page to work like you want. However my work-around for the selected menu item in ASP 4.0 (when leaving RenderingMode to its default), is to mimic the control's generated "selected" CSS class but give mine the "!important" CSS declaration so my styles take precedence where needed.

For instance by default the Menu control renders an "li" element and child "a" for each menu item and the selected menu item's "a" element will contain class="selected" (among other control generated CSS class names including "static" if its a static menu item), therefore I add my own selector to the page (or in a separate stylesheet file) for "static" and "selected" "a" tags like so:

a.selected.static
{
background-color: #f5f5f5 !important;
border-top: Red 1px solid !important;
border-left: Red 1px solid !important;
border-right: Red 1px solid !important;
} 

r'a\\nb'.replace('\\\\', '\\')

or

'a\nb'.replace('\n', '\\n')

when in pyspark multiple conditions can be built using &(for and) and | (for or).

Note:In pyspark t is important to enclose every expressions within parenthesis () that combine to form the condition

%pyspark
dataDF = spark.createDataFrame([(66, "a", "4"), 
                                (67, "a", "0"), 
                                (70, "b", "4"), 
                                (71, "d", "4")],
                                ("id", "code", "amt"))
dataDF.withColumn("new_column",
       when((col("code") == "a") | (col("code") == "d"), "A")
      .when((col("code") == "b") & (col("amt") == "4"), "B")
      .otherwise("A1")).show()

In Spark Scala code (&&) or (||) conditions can be used within when function

//scala
val dataDF = Seq(
      (66, "a", "4"), (67, "a", "0"), (70, "b", "4"), (71, "d", "4"
      )).toDF("id", "code", "amt")
dataDF.withColumn("new_column",
       when(col("code") === "a" || col("code") === "d", "A")
      .when(col("code") === "b" && col("amt") === "4", "B")
      .otherwise("A1")).show()

=======================

Output:
+---+----+---+----------+
| id|code|amt|new_column|
+---+----+---+----------+
| 66|   a|  4|         A|
| 67|   a|  0|         A|
| 70|   b|  4|         B|
| 71|   d|  4|         A|
+---+----+---+----------+

I know this question was asked awhile ago, but I have done this before and it allows for more control when aligning items.If you look at it like web programming, it helps. You just nest another LinearLayout that will contain your button inside of it. You can then change the gravity of the button's layout and make it go to the right while the TextView is still on the left.

Try this code:

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"             
android:orientation="horizontal" 
android:layout_marginTop="35dp">

<TextView
    android:id="@+id/lblExpenseCancel"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/cancel" 
    android:textColor="#404040"         
    android:layout_marginLeft="10dp" 
    android:textSize="20sp" 
    android:layout_marginTop="9dp"/>

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="right"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/btnAddExpense"
        android:layout_width="wrap_content"
        android:layout_height="45dp"
        android:background="@drawable/stitch_button"
        android:layout_marginLeft="10dp"                    
        android:text="@string/add" 
        android:layout_gravity="right" 
        android:layout_marginRight="15dp"/>

</LinearLayout>

You may have to play with the padding on the nested layout so that it acts how you want it.

It's safer to use *arguments.callee.caller since arguments.caller is deprecated...

I ran into a similar problem and stumbled on this question. I got an SMTP Authentication Error but my user name / pass was correct. Here is what fixed it. I read this:

https://support.google.com/accounts/answer/6010255

In a nutshell, google is not allowing you to log in via smtplib because it has flagged this sort of login as "less secure", so what you have to do is go to this link while you're logged in to your google account, and allow the access:

https://www.google.com/settings/security/lesssecureapps

Once that is set (see my screenshot below), it should work.

Login now works:

smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo()
smtpserver.login('[email protected]', 'me_pass')

Response after change:

(235, '2.7.0 Accepted')

Response prior:

smtplib.SMTPAuthenticationError: (535, '5.7.8 Username and Password not accepted. Learn more at\n5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 g66sm2224117qgf.37 - gsmtp')

Still not working? If you still get the SMTPAuthenticationError but now the code is 534, its because the location is unknown. Follow this link:

https://accounts.google.com/DisplayUnlockCaptcha

Click continue and this should give you 10 minutes for registering your new app. So proceed to doing another login attempt now and it should work.

This doesn't seem to work right away you may be stuck for a while getting this error in smptlib:

235 == 'Authentication successful'
503 == 'Error: already authenticated'

The message says to use the browser to sign in:

SMTPAuthenticationError: (534, '5.7.9 Please log in with your web browser and then try again. Learn more at\n5.7.9 https://support.google.com/mail/bin/answer.py?answer=78754 qo11sm4014232igb.17 - gsmtp')

After enabling 'lesssecureapps', go for a coffee, come back, and try the 'DisplayUnlockCaptcha' link again. From user experience, it may take up to an hour for the change to kick in. Then try the sign-in process again.

UPDATE:: See my answer here: How to send an email with Gmail as provider using Python?

Just put this in the header of your PHP Page and it ill work without API:

header('Access-Control-Allow-Origin: *'); //allow everybody  

or

header('Access-Control-Allow-Origin: http://codesheet.org'); //allow just one domain 

or

$http_origin = $_SERVER['HTTP_ORIGIN'];  //allow multiple domains

$allowed_domains = array(
  'http://codesheet.org',
  'http://stackoverflow.com'
);

if (in_array($http_origin, $allowed_domains))
{  
    header("Access-Control-Allow-Origin: $http_origin");
}

It is also possible to pass environment variables explicitly through ssh. It does require some server-side set-up through, so this this not a universal answer.

In my case, I wanted to pass a backup repository encryption key to a command on the backup storage server without having that key stored there, but note that any environment variable is visible in ps! The solution of passing the key on stdin would work as well, but I found it too cumbersome. In any case, here's how to pass an environment variable through ssh:

On the server, edit the sshd_config file, typically /etc/ssh/sshd_config and add an AcceptEnv directive matching the variables you want to pass. See man sshd_config. In my case, I want to pass variables to borg backup so I chose:

AcceptEnv BORG_*

Now, on the client use the -o SendEnv option to send environment variables. The following command line sets the environment variable BORG_SECRET and then flags it to be sent to the client machine (called backup). It then runs printenv there and filters the output for BORG variables:

$ BORG_SECRET=magic-happens ssh -o SendEnv=BORG_SECRET backup printenv | egrep BORG
BORG_SECRET=magic-happens

I think the problem is that the week calculation somehow uses the first day of the year. I don't understand the internal mechanics, but you can see what I mean with this example:

library(data.table)

dd <- seq(as.IDate("2013-12-20"), as.IDate("2014-01-20"), 1)
# dd <- seq(as.IDate("2013-12-01"), as.IDate("2014-03-31"), 1)

dt <- data.table(i = 1:length(dd),
                 day = dd,
                 weekday = weekdays(dd),
                 day_rounded = round(dd, "weeks"))
## Now let's add the weekdays for the "rounded" date
dt[ , weekday_rounded := weekdays(day_rounded)]
## This seems to make internal sense with the "week" calculation
dt[ , weeknumber := week(day)]
dt 

    i        day   weekday day_rounded weekday_rounded weeknumber

     i        day   weekday day_rounded weekday_rounded weeknumber

My workaround is this function: https://github.com/geneorama/geneorama/blob/master/R/round_weeks.R

round_weeks <- function(x){
    require(data.table)
    dt <- data.table(i = 1:length(x),
                     day = x,
                     weekday = weekdays(x))
    offset <- data.table(weekday = c('Sunday', 'Monday', 'Tuesday', 'Wednesday', 
                                     'Thursday', 'Friday', 'Saturday'),
                         offset = -(0:6))
    dt <- merge(dt, offset, by="weekday")
    dt[ , day_adj := day + offset]
    setkey(dt, i)
    return(dt[ , day_adj])
}

Of course, you can easily change the offset to make Monday first or whatever. The best way to do this would be to add an offset to the offset... but I haven't done that yet.

I provided a link to my simple geneorama package, but please don't rely on it too much because it's likely to change and not very documented.

SQL 2005 or later, CTEs are the standard way to go as per the examples shown.

SQL 2000, you can do it using UDFs -

CREATE FUNCTION udfPersonAndChildren
(
    @PersonID int
)
RETURNS @t TABLE (personid int, initials nchar(10), parentid int null)
AS
begin
    insert into @t 
    select * from people p      
    where personID=@PersonID

    while @@rowcount > 0
    begin
      insert into @t 
      select p.*
      from people p
        inner join @t o on p.parentid=o.personid
        left join @t o2 on p.personid=o2.personid
      where o2.personid is null
    end

    return
end

(which will work in 2005, it's just not the standard way of doing it. That said, if you find that the easier way to work, run with it)

If you really need to do this in SQL7, you can do roughly the above in a sproc but couldn't select from it - SQL7 doesn't support UDFs.

In My Case, Im trying to pass messages from Salesforce Marketing Cloud Custom Activity(Domain 1) to Heroku(Domain 2) on load.

The Error Appeared in console, when I loaded my original html page from where message is being passed.

Issue I noticed after reading many blogs is that, the receiver page is not loaded yet. i.e

I need to debug from my receiver page not from sender page.

Simple but glad if it helps anyone.

import json

json_data = json.dumps({
  "result":[
    {
      "run":[
        {
          "action":"stop"
        },
        {
          "action":"start"
        },
        {
          "action":"start"
        }
      ],
      "find": "true"
    }
  ]
})

item_dict = json.loads(json_data)
print len(item_dict['result'][0]['run'])

Convert it in dict.

You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:

 public class ProgramViwer : Form{
  public ProgramViwer()
  {
       InitializeComponent();
       Load += new EventHandler(ProgramViwer_Load);
  }
  private void ProgramViwer_Load(object sender, System.EventArgs e)
  {
       formPanel.Controls.Clear();
       formPanel.Controls.Add(wel);
  }
}

Getting a list of tables:

SELECT 
    Table_Name = Name, 
FROM 
    MSysObjects 
WHERE 
    (Left([Name],1)<>"~") 
    AND (Left([Name],4) <> "MSys") 
    AND ([Type] In (1, 4, 6)) 
ORDER BY 
    Name

I have found the IIS Log files at the following location.

C:\inetpub\logs\LogFiles\

which help to fix my issue.

Here I am giving you a proper example of one callback method . so suppose we have a method like method login() :

 public void login() {
    loginService = new LoginService();
    loginService.login(loginProvider, new LoginListener() {
        @Override
        public void onLoginSuccess() {
            loginService.getresult(true);
        }

        @Override
        public void onLoginFaliure() {
            loginService.getresult(false);

        }
    });
    System.out.print("@@##### get called");
}

I also put all the helper class here to make the example more clear: loginService class

public class LoginService implements Login.getresult{
public void login(LoginProvider loginProvider,LoginListener callback){

    String username  = loginProvider.getUsername();
    String pwd  = loginProvider.getPassword();
    if(username != null && pwd != null){
        callback.onLoginSuccess();
    }else{
        callback.onLoginFaliure();
    }

}

@Override
public void getresult(boolean value) {
    System.out.print("login success"+value);
}}

and we have listener LoginListener as :

interface LoginListener {
void onLoginSuccess();

void onLoginFaliure();

}

now I just wanted to test the method login() of class Login

 @Test
public void loginTest() throws Exception {
    LoginService service = mock(LoginService.class);
    LoginProvider provider = mock(LoginProvider.class);
    whenNew(LoginProvider.class).withNoArguments().thenReturn(provider);
    whenNew(LoginService.class).withNoArguments().thenReturn(service);
    when(provider.getPassword()).thenReturn("pwd");
    when(provider.getUsername()).thenReturn("username");
    login.getLoginDetail("username","password");

    verify(provider).setPassword("password");
    verify(provider).setUsername("username");

    verify(service).login(eq(provider),captor.capture());

    LoginListener listener = captor.getValue();

    listener.onLoginSuccess();

    verify(service).getresult(true);

also dont forget to add annotation above the test class as

@RunWith(PowerMockRunner.class)
@PrepareForTest(Login.class)

If you are using Float or Integer then you can assign default value like this ...

Integer[] data = new Integer[20];
Arrays.fill(data,new Integer(0));

For me the mtime (modification time) is also earlier than the create date in a lot of (most) cases since, as you say, any reorganisation modifies the create time. However, the mtime AFAIUI is an accurate reflection of when the file contents were actually changed so should be an accurate record of video capture date.

After discovering this metadata failure for movie files, I am going to be renaming my videos based on their mtime so I have this stored in a more robust way!

The easiest way is to execute the following command from the command line (see Upgrading the Gradle Wrapper in documentation):

./gradlew wrapper --gradle-version 5.5

Moreover, you can use --distribution-type parameter with either bin or all value to choose a distribution type. Use all distribution type to avoid a hint from IntelliJ IDEA or Android Studio that will offer you to download Gradle with sources:

./gradlew wrapper --gradle-version 5.5 --distribution-type all

Or you can create a custom wrapper task

task wrapper(type: Wrapper) {
    gradleVersion = '5.5'
}

and run ./gradlew wrapper.

It's not that bad, but you forgot to call treeView2.EndUpdate() in your addParentNode_Click() method.
You can also call treeView2.ExpandAll() at the end of your addChildNode_Click() method to see your child node directly.

private void addParentNode_Click(object sender, EventArgs e) {
  treeView2.BeginUpdate();
  //treeView2.Nodes.Clear();
  string yourParentNode;
  yourParentNode = textBox1.Text.Trim();
  treeView2.Nodes.Add(yourParentNode);
  treeView2.EndUpdate();
}

private void addChildNode_Click(object sender, EventArgs e) {
  if (treeView2.SelectedNode != null) {
    string yourChildNode;
    yourChildNode = textBox1.Text.Trim();
    treeView2.SelectedNode.Nodes.Add(yourChildNode);
    treeView2.ExpandAll();
  }
}

I don't know if it was a mistake or not but there was 2 TreeViews. I changed it to only 1 TreeView...

EDIT: Answer to the additional question:
You can declare the variable holding the child node name outside of the if clause:

private void addChildNode_Click(object sender, EventArgs e) {
  var childNode = textBox1.Text.Trim();
  if (!string.IsNullOrEmpty(childNode)) {
    TreeNode parentNode = treeView2.SelectedNode ?? treeView2.Nodes[0];
    if (parentNode != null) {
      parentNode.Nodes.Add(childNode);
      treeView2.ExpandAll();
    }
  }
}

Note: see http://www.yoda.arachsys.com/csharp/csharp2/nullable.html for info about the ?? operator.

You can use a third-party library like base64-img or base64-to-image.

1. base64-img

const base64Img = require('base64-img');

const data = 'data:image/png;base64,...';
const destpath = 'dir/to/save/image';
const filename = 'some-filename';

base64Img.img(data, destpath, filename, (err, filepath) => {}); // Asynchronous using

const filepath = base64Img.imgSync(data, destpath, filename); // Synchronous using

2. base64-to-image

const base64ToImage = require('base64-to-image');

const base64Str = 'data:image/png;base64,...';
const path = 'dir/to/save/image/'; // Add trailing slash

If you're using the iframe and postMessage solution just for this particular problem, I think it might be less work (both code-wise and computation-wise) to just store the data in a subdomain-less cookie and, if it's not already in localStorage on load, grab it from the cookie.

Pros:

• Doesn't need the extra iframe and postMessage set up.

Cons:

• Will make the data available across all subdomains (not just www) so if you don't trust all the subdomains it may not work for you.
• Will send the data to the server on each request. Not great, but depending on your scenario, maybe still less work than the iframe/postMessage solution.
• If you're doing this, why not just use the cookies directly? Depends on your context.
• 4K max cookie size, total across all cookies for the domain (Thanks to Blake for pointing this out in comments)

I agree with other commenters though, this seems like it should be a specifiable option for localStorage so work-arounds aren't required.

Assure you have used method="post" in the form you are sending data from.

If your CPU is spiking to 100% and staying there, it's quite likely that you either have a deadlock scenario or an infinite loop. A profiler seems like a good choice for finding an infinite loop. Deadlocks are much more difficult to track down, however.

You can achieve this by two methods

1. Using XML
2. Using java

Using XML Add this attribute to toolbar XML app:menu = "menu_name"

Using java By overriding onCreateOptionMenu(Menu menu)

public class MainActivity extends AppCompatActivity { 

  private Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
}
@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.demo_menu,menu);
        return super.onCreateOptionsMenu(menu);
    }
}

for more details or implementating click on the menu go through this article https://bedevelopers.tech/android-toolbar-implementation-using-android-studio/

I think the problem is that you are using type="text" instead of textarea. What you want is:

<textarea class="span6" rows="3" placeholder="What's up?" required></textarea>

To clarify, a type="text" will always be one row, where-as a textarea can be multiple.

While rather late to the game, I'll give another solution here as this is still one of the first links to show up on google. Using matplotlib 2.2.2, this can be achieved using the gridspec feature. In the example below the aim is to have four subplots arranged in a 2x2 fashion with the legend shown at the bottom. A 'faux' axis is created at the bottom to place the legend in a fixed spot. The 'faux' axis is then turned off so only the legend shows. Result: https://i.stack.imgur.com/5LUWM.png.

import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec

#Gridspec demo
fig = plt.figure()
fig.set_size_inches(8,9)
fig.set_dpi(100)

rows   = 17 #the larger the number here, the smaller the spacing around the legend
start1 = 0
end1   = int((rows-1)/2)
start2 = end1
end2   = int(rows-1)

gspec = gridspec.GridSpec(ncols=4, nrows=rows)

axes = []
axes.append(fig.add_subplot(gspec[start1:end1,0:2]))
axes.append(fig.add_subplot(gspec[start2:end2,0:2]))
axes.append(fig.add_subplot(gspec[start1:end1,2:4]))
axes.append(fig.add_subplot(gspec[start2:end2,2:4]))
axes.append(fig.add_subplot(gspec[end2,0:4]))

line, = axes[0].plot([0,1],[0,1],'b')           #add some data
axes[-1].legend((line,),('Test',),loc='center') #create legend on bottommost axis
axes[-1].set_axis_off()                         #don't show bottommost axis

fig.tight_layout()
plt.show()

Just to add another unexpected case, here is query that wasn't returning expected results:

*:* AND ( ( field_a:foo AND field_b:bar ) OR !field_b:bar )

field_b in my case is something I perform faceting on, and needed to target the query term "foo" only on that type (bar)

I had to insert another *:* after the or condition to get this to work, like so:

*:* AND ( ( field_a:foo AND field_b:bar ) OR ( *:* AND !field_b:bar ) )

edit: this is in solr 6.6.3

Here's an excellent article by Scott Allen: Developing Gadgets for the Windows Sidebar

This site, Windows 7/Vista Sidebar Gadgets, has links to many gadget resources.

The other methods are all good. However, if you prefer to not specify the field (e.g. for some dynamic method), you can use this:

def __init__(self, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)
    self.fields['email'].widget.attrs['placeholder'] = self.fields['email'].label or '[email protected]'

It also allows the placeholder to depend on the instance for ModelForms with instance specified.

Pretty sure that this exception is thrown when the Excel file is either password protected or the file itself is corrupted. If you just want to read a .xlsx file, try my code below. It's a lot more shorter and easier to read.

import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.Sheet;
//.....

static final String excelLoc = "C:/Documents and Settings/Users/Desktop/testing.xlsx";

public static void ReadExcel() {
InputStream inputStream = null;
   try {
        inputStream = new FileInputStream(new File(excelLoc));
        Workbook wb = WorkbookFactory.create(inputStream);
        int numberOfSheet = wb.getNumberOfSheets();

        for (int i = 0; i < numberOfSheet; i++) {
             Sheet sheet = wb.getSheetAt(i);
             //.... Customize your code here
             // To get sheet name, try -> sheet.getSheetName()
        }
   } catch {}
}

Here is a snippet from me in testing... obviously passing via get to the script may not be the best... should post or just send an id and grab guid from db... anyhow.. this worked. I take the URL and convert it to a path.

// Initialize a file URL to the variable
$file = $_GET['url'];
$file = str_replace(Polepluginforrvms_Plugin::$install_url, $DOC_ROOT.'/pole-permitter/', $file );

$quoted = sprintf('"%s"', addcslashes(basename($file), '"\\'));
$size   = filesize($file);

header( "Content-type: application/octet-stream" );
header( "Content-Disposition: attachment; filename={$quoted}" );
header( "Content-length: " . $size );
header( "Pragma: no-cache" );
header( "Expires: 0" );
readfile( "{$file}" );

You can't put variable definitions in header files, as these will then be a part of all source file you include the header into.

The #pragma once is just to protect against multiple inclusions in the same source file, not against multiple inclusions in multiple source files.

You could declare the variables as extern in the header file, and then define them in a single source file. Or you could declare the variables as const in the header file and then the compiler and linker will manage it.

Just add these two line in your css id #some_div

display: block;
overflow: auto;

After that you will get what your are looking for !

This worked for me. A combination of some of the answers here. And I included the code showing a model only once. And the model goes away when clicked anywhere else.

<script>
    var leave = 0
    //show modal when mouse off of page
    $("html").mouseleave(function() {
       //check for first time
       if (leave < 1) {
          modal.style.display = "block";
          leave = leave + 1;
       }
    });

    // Get the modal with id="id01"
       var modal = document.getElementById('id01');

    // When the user clicks anywhere outside of the modal, close it
       window.onclick = function(event) {
          if (event.target == modal) {
             modal.style.display = "none";
          }
       }
</script>

Set AUTO_INCREMENT to PRIMARY KEY

My clean solution for situation that key is unique in both enumerables:

 private static IEnumerable<TResult> FullOuterJoin<Ta, Tb, TKey, TResult>(
            IEnumerable<Ta> a, IEnumerable<Tb> b,
            Func<Ta, TKey> key_a, Func<Tb, TKey> key_b,
            Func<Ta, Tb, TResult> selector)
        {
            var alookup = a.ToLookup(key_a);
            var blookup = b.ToLookup(key_b);
            var keys = new HashSet<TKey>(alookup.Select(p => p.Key));
            keys.UnionWith(blookup.Select(p => p.Key));
            return keys.Select(key => selector(alookup[key].FirstOrDefault(), blookup[key].FirstOrDefault()));
        }

so

    var ax = new[] {
        new { id = 1, first_name = "ali" },
        new { id = 2, first_name = "mohammad" } };
    var bx = new[] {
        new { id = 1, last_name = "rezaei" },
        new { id = 3, last_name = "kazemi" } };

    var list = FullOuterJoin(ax, bx, a => a.id, b => b.id, (a, b) => "f: " + a?.first_name + " l: " + b?.last_name).ToArray();

outputs:

f: ali l: rezaei
f: mohammad l:
f:  l: kazemi

Using Jquery

Rather than creating temp variables it can be written in a continuous flow pattern as follows:

$('</form>', { action: url, method: 'POST' }).append(
    $('<input>', {type: 'hidden', id: 'id_field_1', name: 'name_field_1', value: val_field_1}),
    $('<input>', {type: 'hidden', id: 'id_field_2', name: 'name_field_2', value: val_field_2}),
).appendTo('body').submit();

I wanted a one-time solution:

ssh -o ServerAliveInterval=60 [email protected]

Stored it in an alias:

alias sshprod='ssh -v -o ServerAliveInterval=60 [email protected]'

Now can connect like this:

me@MyMachine:~$ sshprod

Try the following instead:

<html>
 <head>
  <title>Table row styling</title>
  <style type="text/css">
    .bb td, .bb th {
     border-bottom: 1px solid black !important;
    }
  </style>
 </head>
 <body>
  <table>
    <tr class="bb">
      <td>This</td>
      <td>should</td>
      <td>work</td>
    </tr>
  </table>
 </body>
</html>

EXIT_FAILURE, either in a return statement in main or as an argument to exit(), is the only portable way to indicate failure in a C or C++ program. exit(1) can actually signal successful termination on VMS, for example.

If you're going to be using EXIT_FAILURE when your program fails, then you might as well use EXIT_SUCCESS when it succeeds, just for the sake of symmetry.

On the other hand, if the program never signals failure, you can use either 0 or EXIT_SUCCESS. Both are guaranteed by the standard to signal successful completion. (It's barely possible that EXIT_SUCCESS could have a value other than 0, but it's equal to 0 on every implementation I've ever heard of.)

Using 0 has the minor advantage that you don't need #include <stdlib.h> in C, or #include <cstdlib> in C++ (if you're using a return statement rather than calling exit()) -- but for a program of any significant size you're going to be including stdlib directly or indirectly anyway.

For that matter, in C starting with the 1999 standard, and in all versions of C++, reaching the end of main() does an implicit return 0; anyway, so you might not need to use either 0 or EXIT_SUCCESS explicitly. (But at least in C, I consider an explicit return 0; to be better style.)

(Somebody asked about OpenVMS. I haven't used it in a long time, but as I recall odd status values generally denote success while even values denote failure. The C implementation maps 0 to 1, so that return 0; indicates successful termination. Other values are passed unchanged, so return 1; also indicates successful termination. EXIT_FAILURE would have a non-zero even value.)

@gimel's answer is correct if you can guarantee the package hierarchy he mentions. If you can't -- if your real need is as you expressed it, exclusively tied to directories and without any necessary relationship to packaging -- then you need to work on __file__ to find out the parent directory (a couple of os.path.dirname calls will do;-), then (if that directory is not already on sys.path) prepend temporarily insert said dir at the very start of sys.path, __import__, remove said dir again -- messy work indeed, but, "when you must, you must" (and Pyhon strives to never stop the programmer from doing what must be done -- just like the ISO C standard says in the "Spirit of C" section in its preface!-).

Here is an example that may work for you:

import sys
import os.path
sys.path.append(
    os.path.abspath(os.path.join(os.path.dirname(__file__), os.path.pardir)))

import module_in_parent_dir

Just adding another solution that works for me.. You can simply append it in the marker options:

var marker = new google.maps.Marker({
    map: map, 
    position: position,

    // Custom Attributes / Data / Key-Values
    store_id: id,
    store_address: address,
    store_type: type
});

And then retrieve them with:

marker.get('store_id');
marker.get('store_address');
marker.get('store_type');

I also faced a similar issue. The reason was that I had the changes done in the .aspx page but not the designer page and hence I got the mentioned error. When the reference was created in the designer page I was able to build the solution.

The following seemed to work well for me:

=DATEDIF(B2, Today(), "D")

Update: For bash scripts, the most direct and performant approach is:

if compgen -G "${PROJECT_DIR}/*.png" > /dev/null; then
    echo "pattern exists!"
fi

This will work very speedily even in directories with millions of files and does not involve a new subshell.

Source

The simplest should be to rely on ls return value (it returns non-zero when the files do not exist):

if ls /path/to/your/files* 1> /dev/null 2>&1; then
    echo "files do exist"
else
    echo "files do not exist"
fi

I redirected the ls output to make it completely silent.

EDIT: Since this answer has got a bit of attention (and very useful critic remarks as comments), here is an optimization that also relies on glob expansion, but avoids the use of ls:

for f in /path/to/your/files*; do

    ## Check if the glob gets expanded to existing files.
    ## If not, f here will be exactly the pattern above
    ## and the exists test will evaluate to false.
    [ -e "$f" ] && echo "files do exist" || echo "files do not exist"

    ## This is all we needed to know, so we can break after the first iteration
    break
done

This is very similar to @grok12's answer, but it avoids the unnecessary iteration through the whole list.

You weren't specific, but it looks like you were trying to do what I do in my Win Forms apps: start with a Login form, then after successful login, close that form and put focus on a Main form. Here's how I do it:

1. make frmMain the startup form; this is what my Program.cs looks like:

   [STAThread]
   static void Main()
   {
       Application.EnableVisualStyles();
       Application.SetCompatibleTextRenderingDefault(false);
       Application.Run(new frmMain());
   }
   

2. in my frmLogin, create a public property that gets initialized to false and set to true only if a successful login occurs:

   public bool IsLoggedIn { get; set; }
   

3. my frmMain looks like this:

   private void frmMain_Load(object sender, EventArgs e)
   {
       frmLogin frm = new frmLogin();
       frm.IsLoggedIn = false;
       frm.ShowDialog();
   
       if (!frm.IsLoggedIn)
       {
           this.Close();
           Application.Exit();
           return;
       }
   

No successful login? Exit the application. Otherwise, carry on with frmMain. Since it's the startup form, when it closes, the application ends.

With a simple JSON object, you don't need jQuery:

for (var i in json) {
   for (var j in json[i]) {
     console.log(json[i][j]);
   }
}

You could use label based using .loc or index based using .iloc method to do column-slicing including column ranges:

In [50]: import pandas as pd

In [51]: import numpy as np

In [52]: df = pd.DataFrame(np.random.rand(4,4), columns = list('abcd'))

You need not specify receiver. You can use adb instead.

adb shell am broadcast -a com.whereismywifeserver.intent.TEST 
--es sms_body "test from adb"

For more arguments such as integer extras, see the documentation.

Above answers are helpful, I'd just like to add an example that I think is demonstrating clearly what happens when we pass parameter without the ref keyword, even when that parameter is a reference type:

MyClass c = new MyClass(); c.MyProperty = "foo";

CNull(c); // only a copy of the reference is sent 
Console.WriteLine(c.MyProperty); // still foo, we only made the copy null
CPropertyChange(c); 
Console.WriteLine(c.MyProperty); // bar


private void CNull(MyClass c2)
        {          
            c2 = null;
        }
private void CPropertyChange(MyClass c2) 
        {
            c2.MyProperty = "bar"; // c2 is a copy, but it refers to the same object that c does (on heap) and modified property would appear on c.MyProperty as well.
        }

It prints true on my machine. And it should, otherwise nothing in Java would work as expected. (This is explained in the JLS: 4.3.4 When Reference Types Are the Same)

Do you have multiple classloaders in place?

Ah, and in response to this comment:

I realise I have a typo in my question. I should be like this:

MyImplementedObject obj = new MyImplementedObject ();
if(obj.getClass() == MyObjectInterface.class) System.out.println("true");

MyImplementedObject implements MyObjectInterface So in other words, I am comparing it with its implemented objects.

OK, if you want to check that you can do either:

if(MyObjectInterface.class.isAssignableFrom(obj.getClass()))

or the much more concise

if(obj instanceof MyobjectInterface)

How about this? Assuming SQL Server 2008:

SELECT CAST(StartDate as date) AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

For pre-2008:

SELECT DATEADD(day,datediff(day,0,StartDate),0)   AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

This results in :

ForDate                 | OnHour | Totals

You can use : org.springframework.util.StringUtils;

String stringDelimitedByComma = StringUtils.collectionToCommaDelimitedString(myList);

I tried most commands above on VS Code terminal and I got errors like:

fatal: pathspec '[dir]/[file]' did not match any files

I opened the project on GitHub Desktop and ignored from there and it worked.

Before you call setContentView(), call setTheme(android.R.style...) and just replace the ... with the theme that you want(Theme, Theme_NoTitleBar, etc.).

Or if your theme is a custom theme, then replace the entire thing, so you get setTheme(yourThemesResouceId)

You've way overcomplicated that. Write it with if statements instead like this:

if(liCount == 0)
    setLayoutState('start');
else if(liCount<=5)
    setLayoutState('upload1Row');
else if(liCount<=10)
    setLayoutState('upload2Rows');

$('#UploadList').data('jsp').reinitialise();

Or, if ChaosPandion is trying to optimize as much as possible:

setLayoutState(liCount == 0 ? 'start' :
               liCount <= 5 ? 'upload1Row' :
               liCount <= 10 ? 'upload2Rows' :
               null);

$('#UploadList').data('jsp').reinitialise();

if you use mdb use this code

    var visible_modal = $('.modal.show').attr('id'); // modalID or undefined
    if (visible_modal) { // modal is active
        $('#' + visible_modal).modal('hide'); // close modal
    }

I had the same issue. For me I noticed that the https is using another Certificate which was invalid in terms of expiration date. Not sure why it happened. I changed the Https port number and a new self signed cert. WCFtestClinet could connect to the server via HTTPS!

If you want to remove a particular directory from the rule (meaning, you want to remove the directory foo) ,you can use :

RewriteEngine on

RewriteCond %{REQUEST_URI} !^/foo/$
RewriteRule !index\.php$ /index.php [L]

The rewriteRule above will rewrite all requestes to /index.php excluding requests for /foo/ .

To exclude all existent directries, you will need to use the following condition above your rule :

RewriteCond %{REQUEST_FILENAME} !-d

the following rule

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule !index\.php$ /index.php [L]

rewrites everything (except directries) to /index.php .

In the example you gave, the method will never throw an IOException, therefore the declaration is wrong (but valid). My guess is that the original method threw the IOException, but it was then updated to handle the exception within but the declaration was not changed.

If you are looking specifically for memory in JVM:

Runtime runtime = Runtime.getRuntime();

NumberFormat format = NumberFormat.getInstance();

StringBuilder sb = new StringBuilder();
long maxMemory = runtime.maxMemory();
long allocatedMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();

sb.append("free memory: " + format.format(freeMemory / 1024) + "<br/>");
sb.append("allocated memory: " + format.format(allocatedMemory / 1024) + "<br/>");
sb.append("max memory: " + format.format(maxMemory / 1024) + "<br/>");
sb.append("total free memory: " + format.format((freeMemory + (maxMemory - allocatedMemory)) / 1024) + "<br/>");

However, these should be taken only as an estimate...

DC is your domain. If you want to connect to the domain example.com than your dc's are: DC=example,DC=com

You actually don't need any hostname or ip address of your domain controller (There could be plenty of them).

Just imagine that you're connecting to the domain itself. So for connecting to the domain example.com you can simply write

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");

And you're done.

You can also specify a user and a password used to connect:

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com", "username", "password");

Also be sure to always write LDAP in upper case. I had some trouble and strange exceptions until I read somewhere that I should try to write it in upper case and that solved my problems.

The directoryEntry.Path Property allows you to dive deeper into your domain. So if you want to search a user in a specific OU (Organizational Unit) you can set it there.

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
directoryEntry.Path = "LDAP://OU=Specific Users,OU=All Users,OU=Users,DC=example,DC=com";

This would match the following AD hierarchy:

• com
  • example
    • Users
      • All Users
        • Specific Users

Simply write the hierarchy from deepest to highest.

Now you can do plenty of things

For example search a user by account name and get the user's surname:

DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
DirectorySearcher searcher = new DirectorySearcher(directoryEntry) {
    PageSize = int.MaxValue,
    Filter = "(&(objectCategory=person)(objectClass=user)(sAMAccountName=AnAccountName))"
};

searcher.PropertiesToLoad.Add("sn");

var result = searcher.FindOne();

if (result == null) {
    return; // Or whatever you need to do in this case
}

string surname;

if (result.Properties.Contains("sn")) {
    surname = result.Properties["sn"][0].ToString();
}

IMPORTANT:

We have been using the function as provided above by LPG.

However, this contains a bug you might encounter when you start a process that generates a lot of output. Due to this you might end up with a deadlock when using this function. Instead use the adapted version below:

Function Execute-Command ($commandTitle, $commandPath, $commandArguments)
{
  Try {
    $pinfo = New-Object System.Diagnostics.ProcessStartInfo
    $pinfo.FileName = $commandPath
    $pinfo.RedirectStandardError = $true
    $pinfo.RedirectStandardOutput = $true
    $pinfo.UseShellExecute = $false
    $pinfo.Arguments = $commandArguments
    $p = New-Object System.Diagnostics.Process
    $p.StartInfo = $pinfo
    $p.Start() | Out-Null
    [pscustomobject]@{
        commandTitle = $commandTitle
        stdout = $p.StandardOutput.ReadToEnd()
        stderr = $p.StandardError.ReadToEnd()
        ExitCode = $p.ExitCode
    }
    $p.WaitForExit()
  }
  Catch {
     exit
  }
}

Further information on this issue can be found at MSDN:

A deadlock condition can result if the parent process calls p.WaitForExit before p.StandardError.ReadToEnd and the child process writes enough text to fill the redirected stream. The parent process would wait indefinitely for the child process to exit. The child process would wait indefinitely for the parent to read from the full StandardError stream.

You need to specify a type on person:

void addStudent(struct student person) {
...
}

Also, you can typedef your struct to avoid having to type struct every time you use it:

typedef struct student{
...
} student_t;

void addStudent(student_t person) {
...
}

Maybe this is going a bit too far back but…

Also, I’d like to suggest that multiline text fields have a different type (e.g. “textarea") than single-line fields ("text"), as they really are different types of things, and imply different issues (semantics) for client-side handling.

I presume that your problem with background-image is that it would be inefficient with a source for each image inside a stylesheet. My suggestion is to set the source inline:

<div style = 'background-image: url(image.gif)'></div>

div {
    background-repeat: no-repeat;
    background-position: 50%;
    border-radius: 50%;
    width: 100px;
    height: 100px;
}

Fiddle

Doing something like this should work for you.

<!--[if IE 8]> 
<div id="IE8">
<![endif]--> 

*Your content* 

<!--[if IE 8]> 
</div>
<![endif]--> 

Then your CSS can look like this:

#IE8 div.something
{ 
    color: purple; 
}

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

If you provide string values to your enum, a straight cast works just fine.

enum Color {
  Green = "Green",
  Red = "Red"
}

const color = "Green";
const colorEnum = color as Color;

The res.header('Access-Control-Allow-Origin', '*'); wouldn't work with Autorization header. Just enable pre-flight request, using cors library:

var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
app.options('*', cors())

First, let's clear up some terminology: "asynchronous" (async) means that it may yield control back to the calling thread before it starts. In an async method, those "yield" points are await expressions.

This is very different than the term "asynchronous", as (mis)used by the MSDN documentation for years to mean "executes on a background thread".

To futher confuse the issue, async is very different than "awaitable"; there are some async methods whose return types are not awaitable, and many methods returning awaitable types that are not async.

Enough about what they aren't; here's what they are:

• The async keyword allows an asynchronous method (that is, it allows await expressions). async methods may return Task, Task<T>, or (if you must) void.
• Any type that follows a certain pattern can be awaitable. The most common awaitable types are Task and Task<T>.

So, if we reformulate your question to "how can I run an operation on a background thread in a way that it's awaitable", the answer is to use Task.Run:

private Task<int> DoWorkAsync() // No async because the method does not need await
{
  return Task.Run(() =>
  {
    return 1 + 2;
  });
}

(But this pattern is a poor approach; see below).

But if your question is "how do I create an async method that can yield back to its caller instead of blocking", the answer is to declare the method async and use await for its "yielding" points:

private async Task<int> GetWebPageHtmlSizeAsync()
{
  var client = new HttpClient();
  var html = await client.GetAsync("http://www.example.com/");
  return html.Length;
}

So, the basic pattern of things is to have async code depend on "awaitables" in its await expressions. These "awaitables" can be other async methods or just regular methods returning awaitables. Regular methods returning Task/Task<T> can use Task.Run to execute code on a background thread, or (more commonly) they can use TaskCompletionSource<T> or one of its shortcuts (TaskFactory.FromAsync, Task.FromResult, etc). I don't recommend wrapping an entire method in Task.Run; synchronous methods should have synchronous signatures, and it should be left up to the consumer whether it should be wrapped in a Task.Run:

private int DoWork()
{
  return 1 + 2;
}

private void MoreSynchronousProcessing()
{
  // Execute it directly (synchronously), since we are also a synchronous method.
  var result = DoWork();
  ...
}

private async Task DoVariousThingsFromTheUIThreadAsync()
{
  // I have a bunch of async work to do, and I am executed on the UI thread.
  var result = await Task.Run(() => DoWork());
  ...
}

I have an async/await intro on my blog; at the end are some good followup resources. The MSDN docs for async are unusually good, too.

Updated answer for 2019 - the cocoa pods team moved to using their own CDN which solves this issue, which was due to GitHub rate limiting, as described here: https://blog.cocoapods.org/CocoaPods-1.7.2/

TL;DR You need to change the source line in your Podfile to this:

source 'https://cdn.cocoapods.org/'

Click the left mouse button, drag across the section you want to copy and release. The code automatically gets copied to clipboard.

It's possible to argue that using SSHs key to authenticate is less secure because we tend to change our password more periodically than we generate new SSH keys.

Servers that limit the lifespan for which they'll honor given SSH keys can help force users toward the practice of refreshing SSH-keys periodically.

This may be the easiest method

• Right click on the project and select "Add Service Reference..."
• In the Address: box, enter the physical path (C:\test\project....) of the downloaded/Modified wsdl.
• Hit Go

I suggest you to start with simple polynomial fit, scipy.optimize.curve_fit tries to fit a function f that you must know to a set of points.

This is a simple 3 degree polynomial fit using numpy.polyfit and poly1d, the first performs a least squares polynomial fit and the second calculates the new points:

import numpy as np
import matplotlib.pyplot as plt

points = np.array([(1, 1), (2, 4), (3, 1), (9, 3)])
# get x and y vectors
x = points[:,0]
y = points[:,1]

# calculate polynomial
z = np.polyfit(x, y, 3)
f = np.poly1d(z)

# calculate new x's and y's
x_new = np.linspace(x[0], x[-1], 50)
y_new = f(x_new)

plt.plot(x,y,'o', x_new, y_new)
plt.xlim([x[0]-1, x[-1] + 1 ])
plt.show()

I want to mention additional things and make a conclusion.

Commonly, As Otherones explained, This exception will raise when there is a problem with loading expected type (in an existing assembly) in runtime. More specific, Whenever there is loaded assembly that is stale (and not contains the requiring type). Or when an assembly with different version or build is already loaded that not contains the expected type.

Also, I must mention that It seems Rarely, But It is possible to be runtime limitation or a compiler bug (suppose compiler not negated about something and just compiled problematic code), But runtime throws System.TypeLoadException exception. Yes; this actually occurred for me!

An Example (witch occurred for me)

Consider an struct that defines a nullable field of its own type inside itself. Defining such the filed non-nullable, will take you a compile-time error and prevents you from build (Obviously This behavior has a logical reason). But what about nullable struct filed? Actually, nullable value-types is Nullable<T> at behind. As c# compiler not prevented me from defining in this way, I tried it and the project built. But I get runtime exception System.TypeLoadException: 'Could not load type 'SomeInfo' from assembly ... ', And It seems to be Problem in loading the part of my code (otherwise, we may say: the compiler not-truly performed compilation process at least) for me in my environment:

public struct SomeInfo
{
   public SomeInfo? Parent { get; } 
   
   public string info { get; }
}

My environment specs:

• Visual Studio 2019 16.4.4
• Language Version: c# 7.3
• Project type: netstandard 2.0.3 library
• Runtime: classic DotNetFramework 4.6.1

(I checked and ensured that the compiled assembly is up to date And actually is newly compiled. Even, I throwed away all bin directory and refreshed the whole project. Even I created a new project in a fresh solution and tested, But such the struct generates the exception.)

It seems to be a runtime limitation (logically or technically) or bug or a same problem else, because Visual Studio not prevents me from compile And Also other newer parts of my codes (excluding this struct) are executing fine. Changing the struct to a class, the compiled assembly contains and executes the type as well.

I have no any idea to explain in-detail why this behavior occurs in my environment, But I faced this situation.

Conclusion

Check the situations:

• When a same (probably older) assembly already exists in GAC that is overriding the referenced assembly.

• When re-compilation was need but not performed automatically (therefore the referenced assembly is not updated) and there is needs to perform build manually or fix solution build configuration.

• When a custom tool or middleware or third-party executable (such as tests runner tool or IIS) loaded an older version of that assembly from cached things and there is need to cleaning somethings up or causing to reset somethings.

• When an Unappropriated Configuration caused demanding a no longer existing type by a custom tool or middleware or a third-party executable that loads the assembly and there is need to update configuration or cleaning somethings up (such as removing an http handler in web.config file on IIS deployment as @Brian-Moeskau said)

• When there is a logical or technical problem for runtime to execute the compiled assembly, (for example when compiler was compiled a problematic code that the in-using runtime cannot understand or execute it), as I faced.

<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:padding="10dp"
  android:shape="rectangle">
    <solid android:color="@color/colorAccent" /> 
    <corners
      android:bottomLeftRadius="500dp"
      android:bottomRightRadius="500dp"
      android:topLeftRadius="500dp"
      android:topRightRadius="500dp" />
</shape>

Now, in which element you want to use this shape just add: android:background="@drawable/custom_round_ui_shape"

Create a new XML in drawable named "custom_round_ui_shape"

If you use any full screen window (having its WindowState = WindowState.Maximized, WindowStyle = WindowStyle.None), you can wrap its contents in System.Windows.Controls.Canvas like this:

<Canvas Name="MyCanvas" Width="auto" Height="auto">
...
</Canvas>

Then you can use MyCanvas.ActualWidth and MyCanvas.ActualHeight to get the resolution of the current screen, with DPI settings taken into account and in device independent units. It doesn't add any margins as the maximized window itself does.

(Canvas accepts UIElements as children, so you should be able to use it with any content.)

Assuming you have:

HashMap<Key, Value> map; // Assigned or populated somehow.

For a list of values:

List<Value> values = new ArrayList<Value>(map.values());

For a list of keys:

List<Key> keys = new ArrayList<Key>(map.keySet());

Note that the order of the keys and values will be unreliable with a HashMap; use a LinkedHashMap if you need to preserve one-to-one correspondence of key and value positions in their respective lists.

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.

If we know there is a limitation on LEN and space, why cant we replace the space first? Then we know there is no space to confuse LEN.

len(replace(@string, ' ', '-')) - len(replace(replace(@string, ' ', '-'), ',', ''))

Below is reference from https://android.googlesource.com/platform/tools/tradefederation/+/master/src/com/android/tradefed/util/FileUtil.java

/**
 * Gets the base name, without extension, of given file name.
 * <p/>
 * e.g. getBaseName("file.txt") will return "file"
 *
 * @param fileName
 * @return the base name
 */
public static String getBaseName(String fileName) {
    int index = fileName.lastIndexOf('.');
    if (index == -1) {
        return fileName;
    } else {
        return fileName.substring(0, index);
    }
}

use auto and min or max width like this:

td {
max-width:50px;
width:auto;
min-width:10px;
}

The regular expression I ended up using for when I want to allow spaces in the middle of my string, but not at the beginning or end was this:

[\S]+(\s[\S]+)*

or

^[\S]+(\s[\S]+)*$

So, I know this is an old question, but you could do something like:

if (/^\s+$/.test(myString)) {
    //string contains characters and white spaces
}

or you can do what nickf said and use:

if (/\S/.test(myString)) {
    // string is not empty and not just whitespace
}

Strings in C are represented as arrays of characters.

char *p = "String";

You are declaring a pointer that points to a string stored some where in your program (modifying this string is undefined behavior) according to the C programming language 2 ed.

char p2[] = "String";

You are declaring an array of char initialized with the string "String" leaving to the compiler the job to count the size of the array.

char p3[5] = "String";

You are declaring an array of size 5 and initializing it with "String". This is an error be cause "String" don't fit in 5 elements.

char p3[7] = "String"; is the correct declaration ('\0' is the terminating character in c strings).

As of March 30, 2012, I have tried and failed to get the sloonz fork on GitHub to open images. I got it to compile ok, but it didn't actually work. I also tried building gohlke's library, and it compiled also but failed to open any images. Someone mentioned PythonMagick above, but it only compiles on Windows. See PythonMagick on the wxPython wiki.

PIL was last updated in 2009, and while it's website says they are working on a Python 3 port, it's been 3 years, and the mailing list has gone cold.

To solve my Python 3 image manipulation problem, I am using subprocess.call() to execute ImageMagick shell commands. This method works.

See the subprocess module documentation.

For Amazon AWS ECS/ECR, you should manage your environment variables (especially secrets) via a private S3 bucket. See blog post How to Manage Secrets for Amazon EC2 Container Service–Based Applications by Using Amazon S3 and Docker.

You can achieve this by a few lines of CSS and JS.

CSS:

        div.clip-context {
          max-height: 95px;
          word-break: break-all;
          white-space: normal;
          word-wrap: break-word; //Breaking unicode line for MS-Edge works with this property;
        }

JS:

        $(document).ready(function(){
             for(let c of $("div.clip-context")){
                    //If each of element content exceeds 95px its css height, extract some first 
                    //lines by specifying first length of its text content. 
                   if($(c).innerHeight() >= 95){
                        //Define text length for extracting, here 170.
                        $(c).text($(c).text().substr(0, 170)); 
                        $(c).append(" ...");
                   }
             }

        });

HTML:

        <div class="clip-context">
            (Here some text)
        </div>

graphics.h appears to something once bundled with Borland and/or Turbo C++, in the 90's.

It's unlikely that you will find any support for that file with modern compiler. For other graphics libraries check the list of "related" questions (questions related to this one). E.g., "A Simple, 2d cross-platform graphics library for c or c++?".

To finally answer the title question: It is (a client side setting) in (project, profile or settings)

[plugin]?[r|R]epository/[releases|snapshots]/updatePolicy

... tag.

The (currently, maven: 3.6.0, but I suppose "far backwards" compatible) possible values are :

/**
 * Never update locally cached data.
 */
public static final String UPDATE_POLICY_NEVER = "never";
/**
 * Always update locally cached data.
 */
public static final String UPDATE_POLICY_ALWAYS = "always";
/**
 * Update locally cached data once a day.
 */
public static final String UPDATE_POLICY_DAILY = "daily";
/**
 * Update locally cached data **every X minutes** as given by "interval:X".
 */
public static final String UPDATE_POLICY_INTERVAL = "interval";

The current (maven 3.6.0) evaluation of this tag is implemented as follows:

public boolean isUpdatedRequired( RepositorySystemSession session, long lastModified, String policy )
{
    boolean checkForUpdates;
    if ( policy == null )
    {
        policy = "";
    }
    if ( RepositoryPolicy.UPDATE_POLICY_ALWAYS.equals( policy ) )
    {
        checkForUpdates = true;
    }
    else if ( RepositoryPolicy.UPDATE_POLICY_DAILY.equals( policy ) )
    {
        Calendar cal = Calendar.getInstance();
        cal.set( Calendar.HOUR_OF_DAY, 0 );
        cal.set( Calendar.MINUTE, 0 );
        cal.set( Calendar.SECOND, 0 );
        cal.set( Calendar.MILLISECOND, 0 );
        checkForUpdates = cal.getTimeInMillis() > lastModified;
    }
    else if ( policy.startsWith( RepositoryPolicy.UPDATE_POLICY_INTERVAL ) )
    {
        int minutes = getMinutes( policy );
        Calendar cal = Calendar.getInstance();
        cal.add( Calendar.MINUTE, -minutes );
        checkForUpdates = cal.getTimeInMillis() > lastModified;
    }
    else
    {
        // assume "never"
        checkForUpdates = false;
        if ( !RepositoryPolicy.UPDATE_POLICY_NEVER.equals( policy ) )
        {
            LOGGER.warn( "Unknown repository update policy '{}', assuming '{}'",
                    policy, RepositoryPolicy.UPDATE_POLICY_NEVER );
        }
    }
    return checkForUpdates;
}

..with:

private int getMinutes( String policy )
{
    int minutes;
    try
    {
        String s = policy.substring( RepositoryPolicy.UPDATE_POLICY_INTERVAL.length() + 1 );
        minutes = Integer.valueOf( s );
    }
    catch ( RuntimeException e )
    {
        minutes = 24 * 60;
        LOGGER.warn( "Non-parseable repository update policy '{}', assuming '{}:1440'",
                policy, RepositoryPolicy.UPDATE_POLICY_INTERVAL );
    }
    return minutes;
}

...where lastModified is the (local file) "modified timestamp" of an/each underlying artifact.

In particular for the interval:x setting:

• the colon : is not that strict - any "non-empty" character could do it (=, , ...).
• negative values x < 0 should yield to "never".
• interval:0 I would assume a "minutely" (0-59 secs. or above...) interval.
• number format exceptions result in 24 * 60 minutes (~"daily").

First you download ODBC driver psqlodbc_09_01_0200-x64.zip then you installed it.After that go to START->Program->Administrative tools then you select Data Source ODBC then you double click on the same after that you select PostgreSQL 30 then you select configure then you provide proper details such as db name user Id host name password of the same database in this way you will configured your DSN connection.After That you will check SSL should be allow .

Then you go on next tab system DSN then you select ADD tabthen select postgreSQL_ANSI_64X ODBC after you that you have created PostgreSQL ODBC connection.

The problem is your plugin. To solve this is to only enter this address:

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

This will print the data in columns and comes to new line once last column is reached.

                    System.out.print(res.getString(i)+"\t");
                }
                else{
                    System.out.println(res.getString(i));
                }

            }

// Returns bottom offset value + or - from viewport top
function offsetBottom(el, i) { i = i || 0; return $(el)[i].getBoundingClientRect().bottom }

// Returns right offset value
function offsetRight(el, i) { i = i || 0; return $(el)[i].getBoundingClientRect().right }

var bottom = offsetBottom('#logo');
var right = offsetRight('#logo');

This will find the distance from the top and left of your viewport to your element's exact edge and nothing beyond that. So say your logo was 350px and it had a left margin of 50px, variable 'right' will hold a value of 400 because that's the actual distance in pixels it took to get to the edge of your element, no matter if you have more padding or margin to the right of it.

If your box-sizing CSS property is set to border-box it will continue to work just as if it were set as the default content-box.

whichAndroidVersion= Build.VERSION.SDK_INT;
textView.setText("" + whichAndroidVersion); //If you don't use "" then app crashes.

For example, that code above will set the text into my textView as "29" now.

How about exporting the variable, but only inside the subshell?:

(export FOO=bar && somecommand someargs | somecommand2)

Keith has a point, to unconditionally execute the commands, do this:

(export FOO=bar; somecommand someargs | somecommand2)

There are a plethora of ways in which this can be done. The problem is how to make R aware of the locations of the variables you wish to divide.

Assuming

d <- read.table(text = "263807.0    1582
196190.5    1016
586689.0    3479
")
names(d) <- c("min", "count2.freq")
> d
       min count2.freq
1 263807.0        1582
2 196190.5        1016
3 586689.0        3479

My preferred way

To add the desired division as a third variable I would use transform()

> d <- transform(d, new = min / count2.freq)
> d
       min count2.freq      new
1 263807.0        1582 166.7554
2 196190.5        1016 193.1009
3 586689.0        3479 168.6373

The basic R way

If doing this in a function (i.e. you are programming) then best to avoid the sugar shown above and index. In that case any of these would do what you want

## 1. via `[` and character indexes
d[, "new"] <- d[, "min"] / d[, "count2.freq"]

## 2. via `[` with numeric indices
d[, 3] <- d[, 1] / d[, 2]

## 3. via `$`
d$new <- d$min / d$count2.freq

All of these can be used at the prompt too, but which is easier to read:

d <- transform(d, new = min / count2.freq)

or

d$new <- d$min / d$count2.freq ## or any of the above examples

Hopefully you think like I do and the first version is better ;-)

The reason we don't use the syntactic sugar of tranform() et al when programming is because of how they do their evaluation (look for the named variables). At the top level (at the prompt, working interactively) transform() et al work just fine. But buried in function calls or within a call to one of the apply() family of functions they can and often do break.

Likewise, be careful using numeric indices (## 2. above); if you change the ordering of your data, you will select the wrong variables.

The preferred way if you don't need replacement

If you are just wanting to do the division (rather than insert the result back into the data frame, then use with(), which allows us to isolate the simple expression you wish to evaluate

> with(d, min / count2.freq)
[1] 166.7554 193.1009 168.6373

This is again much cleaner code than the equivalent

> d$min / d$count2.freq
[1] 166.7554 193.1009 168.6373

as it explicitly states that "using d, execute the code min / count2.freq. Your preference may be different to mine, so I have shown all options.

An easy way would be to use $toLower as below.

db.users.aggregate([
    {
        $project: {
            name: { $toLower: "$name" }
        }
    },
    {
        $match: {
            name: the_name_to_search
        }
    }
])

Use nmp configuration file (add it to your web project) then add the needed packages in the same way we did using bower.json and save. Visual studio will download and install it. You'll find the package the under the nmp node of your project.

Why is it necessary for an interface to be "declared" abstract?

It's not.

public abstract interface Interface {
       \___.__/
           |
           '----> Neither this...

    public void interfacing();
    public abstract boolean interfacing(boolean really);
           \___.__/
               |
               '----> nor this, are necessary.
}

Interfaces and their methods are implicitly abstract and adding that modifier makes no difference.

Is there other rules that applies with an abstract interface?

No, same rules apply. The method must be implemented by any (concrete) implementing class.

If abstract is obsolete, why is it included in Java? Is there a history for abstract interface?

Interesting question. I dug up the first edition of JLS, and even there it says "This modifier is obsolete and should not be used in new Java programs".

Okay, digging even further... After hitting numerous broken links, I managed to find a copy of the original Oak 0.2 Specification (or "manual"). Quite interesting read I must say, and only 38 pages in total! :-)

Under Section 5, Interfaces, it provides the following example:

public interface Storing {
    void freezeDry(Stream s) = 0;
    void reconstitute(Stream s) = 0;
}

And in the margin it says

In the future, the " =0" part of declaring methods in interfaces may go away.

Assuming =0 got replaced by the abstract keyword, I suspect that abstract was at some point mandatory for interface methods!

https://docs.angularjs.org/guide/$location#html-link-rewriting

In cases like the following, links are not rewritten; instead, the browser will perform a full page reload to the original link.

• Links that contain target element Example:
  <a href="/ext/link?a=b" target="_self">link</a>

• Absolute links that go to a different domain Example:
  <a href="http://angularjs.org/">link</a>

• Links starting with '/' that lead to a different base path when base is defined Example:
  <a href="/not-my-base/link">link</a>

So in your case, you should add a target attribute like so...

<a target="_self" href="example.com/uploads/asd4a4d5a.pdf" download="foo.pdf">

If M2_HOME is configured to point to the Maven home directory then:

1. Go to File -> Settings
2. Search for Maven
3. Select Runner

4. Insert in the field VM Options the following string:

   Dmaven.multiModuleProjectDirectory=$M2_HOME
   

Click Apply and OK

Bash sets the shell variable OSTYPE. From man bash:

Automatically set to a string that describes the operating system on which bash is executing.

This has a tiny advantage over uname in that it doesn't require launching a new process, so will be quicker to execute.

However, I'm unable to find an authoritative list of expected values. For me on Ubuntu 14.04 it is set to 'linux-gnu'. I've scraped the web for some other values. Hence:

case "$OSTYPE" in
  linux*)   echo "Linux / WSL" ;;
  darwin*)  echo "Mac OS" ;; 
  win*)     echo "Windows" ;;
  msys*)    echo "MSYS / MinGW / Git Bash" ;;
  cygwin*)  echo "Cygwin" ;;
  bsd*)     echo "BSD" ;;
  solaris*) echo "Solaris" ;;
  *)        echo "unknown: $OSTYPE" ;;
esac

The asterisks are important in some instances - for example OSX appends an OS version number after the 'darwin'. The 'win' value is actually 'win32', I'm told - maybe there is a 'win64'?

Perhaps we could work together to populate a table of verified values here:

• Linux Ubuntu (incl. WSL): linux-gnu
• Cygwin 64-bit: cygwin
• Msys/MINGW (Git Bash for Windows): msys

(Please append your value if it differs from existing entries)

I would make a very simple VBScript file and call it using CScript to parse the command line parameters.

Something like the following saved in MessageBox.vbs:

Set objArgs = WScript.Arguments
messageText = objArgs(0)
MsgBox messageText

Which you would call like:

cscript MessageBox.vbs "This will be shown in a popup."

MsgBox reference if you are interested in going this route.

Deleting the hidden .vs folder didn't work for me since the port specified in my app was being used by another app. Doing the following worked for me:

1. Went to properties and then click the web tab.
2. Changed the port number in the Start Url and the Project URL.
3. Clicked Create Virtual Directory.
4. Save and Press F5.

As Quentin and other suggested this cannot totally be done with css(partially done with content attribute of css). Instead you should use javascript/jQuery to achieve this,

JS:

document.getElementsByClassName("mandatory")[0].title = "mandatory";

or using jQuery:

$('.mandatory').attr('title','mandatory');

document.getElementsByClassName('mandatory')[0].setAttribute('title', 'mandatory');_x000D_
_x000D_
$('.jmandatory').attr('title', 'jmandatory');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
Place the Mouse Over the following elements to see the title,_x000D_
<br/><br/>_x000D_
<b><label class="mandatory">->Javascript Mandatory</label></b>_x000D_
<br/><br/>_x000D_
<b><label class="jmandatory">->jQuery Mandatory</label></b>

Put it this way

where ("R"."TIME_STAMP">=TO_DATE ('03-02-2013 00:00:00', 'DD-MM-YYYY HH24:MI:SS')
   AND "R"."TIME_STAMP"<=TO_DATE ('09-02-2013 23:59:59', 'DD-MM-YYYY HH24:MI:SS')) 

Where R is table name.
TIME_STAMP is FieldName in Table R.

My VPN connection was not enabled. I was trying all possible way to open up the Firwall and Ports until I realized, I am working from home and my VPN connection was down. But yes, Firewall and ssh configurations can be a reason.

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

Here is how to get the Guid's programmatically! You can then use these guids/filepaths with an above answer to add the reference!

Reference: http://www.vbaexpress.com/kb/getarticle.php?kb_id=278

Sub ListReferencePaths()
'Lists path and GUID (Globally Unique Identifier) for each referenced library.
'Select a reference in Tools > References, then run this code to get GUID etc.
    Dim rw As Long, ref
    With ThisWorkbook.Sheets(1)
        .Cells.Clear
        rw = 1
        .Range("A" & rw & ":D" & rw) = Array("Reference","Version","GUID","Path")
        For Each ref In ThisWorkbook.VBProject.References
            rw = rw + 1
            .Range("A" & rw & ":D" & rw) = Array(ref.Description, _
                   "v." & ref.Major & "." & ref.Minor, ref.GUID, ref.FullPath)
        Next ref
        .Range("A:D").Columns.AutoFit
    End With
End Sub

Here is the same code but printing to the terminal if you don't want to dedicate a worksheet to the output.

Sub ListReferencePaths() 
 'Macro purpose:  To determine full path and Globally Unique Identifier (GUID)
 'to each referenced library.  Select the reference in the Tools\References
 'window, then run this code to get the information on the reference's library

On Error Resume Next 
Dim i As Long 

Debug.Print "Reference name" & " | " & "Full path to reference" & " | " & "Reference GUID" 

For i = 1 To ThisWorkbook.VBProject.References.Count 
  With ThisWorkbook.VBProject.References(i) 
    Debug.Print .Name & " | " & .FullPath  & " | " & .GUID 
  End With 
Next i 
On Error GoTo 0 
End Sub 

You have to use Popen like this:

cmd = ['sudo', 'apache2ctl', 'restart']
proc = subprocess.Popen(cmd, shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

It expects a list.

The trick is to know the content id of the Image mime part when building the html body part. It boils down to making the img tag

https://github.com/horde/horde/blob/master/kronolith/lib/Kronolith.php

Look at the function buildMimeMessage for a working example.

If you intend to use the times later to compute with, learn how to use the -f option of /usr/bin/time to output code that saves times. Here's some code I used recently to get and sort the execution times of a whole classful of students' programs:

fmt="run { date = '$(date)', user = '$who', test = '$test', host = '$(hostname)', times = { user = %U, system = %S, elapsed = %e } }"
/usr/bin/time -f "$fmt" -o $timefile command args...

I later concatenated all the $timefile files and pipe the output into a Lua interpreter. You can do the same with Python or bash or whatever your favorite syntax is. I love this technique.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

What works for me: style tag with @import rule

<defs>
    <style type="text/css">
        @import url("svg-common.css");
    </style>
</defs>

There are already a lot of great answers here but it's worth mentioning a simple and quick way to get the SQL Server Database size with SQL Server Management Studio (SSMS) using a standard report.

To run a report you need:

1. right-click on the database
2. go to Reports > Standard Reports > Disk Usage.

It prints a nice report:

Where the Total space Reserved is the total size of the database on the disk and it includes the size of all data files and the size of all transaction log files.

Under the hood, SSMS uses dbo.sysfiles view or sys.database_files view (depending on the version of MSSQL) and some kind of this query to get the Total space Reserved value:

SELECT sum((convert(dec (19, 2),  
convert(bigint,SIZE))) * 8192 / 1048576.0) db_size_mb
FROM dbo.sysfiles;

In Python 2.7.3:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError as e:
    print type(e)    #not catch
except socket.timeout as e:
    print type(e)    #catched
    raise MyException("There was an error: %r" % e)

You could try using LocationManager.addGpsStatusListener to get updated when the GPS status changes. It looks like GPS_EVENT_STARTED and GPS_EVENT_STOPPED might be what you're looking for.

This script is a improvement of the script from Vector. I have made a little change to it. So this script works for every link with the class page-scroll in it.

At first without easing:

$("a.page-scroll").click(function() {
    var targetDiv = $(this).attr('href');
    $('html, body').animate({
        scrollTop: $(targetDiv).offset().top
    }, 1000);
});

For easing you will need Jquery UI:

<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>

Add this to the script:

'easeOutExpo'

Final

$("a.page-scroll").click(function() {
    var targetDiv = $(this).attr('href');
    $('html, body').animate({
        scrollTop: $(targetDiv).offset().top
    }, 1000, 'easeOutExpo');
});

All the easings you can find here: Cheat Sheet.

I might be a bit late to answer this but this will be useful for new people looking for this answer.

The answers above are good, but to have a perfect video background you have to check at the aspect ratio as the video might cut or the canvas around get deformed when resizing the screen or using it on different screen sizes.

I got into this issue not long ago and I found the solution using media queries.

Here is a tutorial that I wrote on how to create a Fullscreen Video Background with only CSS

I will add the code here as well:

HTML:

<div class="videoBgWrapper">
    <video loop muted autoplay poster="img/videoframe.jpg" class="videoBg">
        <source src="videosfolder/video.webm" type="video/webm">
        <source src="videosfolder/video.mp4" type="video/mp4">
        <source src="videosfolder/video.ogv" type="video/ogg">
    </video>
</div>

CSS:

.videoBgWrapper {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    overflow: hidden;
    z-index: -100;
}
.videoBg{
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

@media (min-aspect-ratio: 16/9) {
  .videoBg{
    width: 100%;
    height: auto;
  }
}
@media (max-aspect-ratio: 16/9) {
  .videoBg {
    width: auto;
    height: 100%;
  }
}

I hope you find it useful.

From the docs:

The comparison uses lexicographical ordering: first the first two items are compared, and if they differ this determines the outcome of the comparison; if they are equal, the next two items are compared, and so on, until either sequence is exhausted.

Also:

Lexicographical ordering for strings uses the Unicode code point number to order individual characters.

or on Python 2:

Lexicographical ordering for strings uses the ASCII ordering for individual characters.

As an example:

>>> 'abc' > 'bac'
False
>>> ord('a'), ord('b')
(97, 98)

The result False is returned as soon as a is found to be less than b. The further items are not compared (as you can see for the second items: b > a is True).

Be aware of lower and uppercase:

>>> [(x, ord(x)) for x in abc]
[('a', 97), ('b', 98), ('c', 99), ('d', 100), ('e', 101), ('f', 102), ('g', 103), ('h', 104), ('i', 105), ('j', 106), ('k', 107), ('l', 108), ('m', 109), ('n', 110), ('o', 111), ('p', 112), ('q', 113), ('r', 114), ('s', 115), ('t', 116), ('u', 117), ('v', 118), ('w', 119), ('x', 120), ('y', 121), ('z', 122)]
>>> [(x, ord(x)) for x in abc.upper()]
[('A', 65), ('B', 66), ('C', 67), ('D', 68), ('E', 69), ('F', 70), ('G', 71), ('H', 72), ('I', 73), ('J', 74), ('K', 75), ('L', 76), ('M', 77), ('N', 78), ('O', 79), ('P', 80), ('Q', 81), ('R', 82), ('S', 83), ('T', 84), ('U', 85), ('V', 86), ('W', 87), ('X', 88), ('Y', 89), ('Z', 90)]

Boosting your maven-compiler-plugin to 3.8.0 seems to be necessary but not sufficient. If you're still having problems, you should also make sure your JAVA_HOME environment variable is set to Java 10 (or 11) if you're running from the command line. (The error message you get won't tell you this.) Or if you're running from an IDE, you need to make sure it is set to run maven with your current JDK.

If you want to pass variables from the current function, another way to do this is, for example:

document.getElementById("space1").onclick = new Function("lrgWithInfo('"+myVar+"')");

If you don't need to pass information from this function, it's just:

document.getElementById("space1").onclick = new Function("lrgWithInfo('13')");

You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

You can try progress bar instead of seek bar

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="fill_parent"
    android:layout_height="50dp"
    android:layout_marginBottom="35dp"
    />

The documentation says that these two methods are equivalent:

StreamReader.Close: This implementation of Close calls the Dispose method passing a true value.

StreamWriter.Close: This implementation of Close calls the Dispose method passing a true value.

Stream.Close: This method calls Dispose, specifying true to release all resources.

So, both of these are equally valid:

/* Option 1, implicitly calling Dispose */
using (StreamWriter writer = new StreamWriter(filename)) { 
   // do something
} 

/* Option 2, explicitly calling Close */
StreamWriter writer = new StreamWriter(filename)
try {
    // do something
}
finally {
    writer.Close();
}

Personally, I would stick with the first option, since it contains less "noise".

Here's a simple solution that checks if you are in a Windows or posix-like (Linux/Unix/Cygwin/Mac) environment:

ifeq ($(shell echo "check_quotes"),"check_quotes")
   WINDOWS := yes
else
   WINDOWS := no
endif

It takes advantage of the fact that echo exists on both posix-like and Windows environments, and that in Windows the shell does not filter the quotes.

Similar to POsha's answer but this is what worked for me on ubuntu 19

sudo npm i -g ngrok --unsafe-perm=true --allow-root

sudo rm -rf /Library/Internet\ Plug-Ins/Java*

Even if I want to return a business logic error as HTTP code there is no such acceptable HTTP error code for that errors rather than using HTTP 200 because it will misrepresent the actual error.

So, HTTP 200 will be good for business logic errors. But all errors which are covered by HTTP error codes should use them.

Basically HTTP 200 means what server correctly processes user request (in case of there is no seats on the plane it is no matter because user request was correctly processed, it can even return just a number of seats available on the plane, so there will be no business logic errors at all or that business logic can be on client side. Business logic error is an abstract meaning, but HTTP error is more definite).

df=pd.read_csv("filename.csv" , parse_dates=["<column name>"])

type(df.<column name>)

example: if you want to convert day which is initially a string to a Timestamp in Pandas

df=pd.read_csv("weather_data2.csv" , parse_dates=["day"])

type(df.day)

The output will be pandas.tslib.Timestamp

ng-init is a directive that can be placed inside div's, span's, whatever, whereas onload is an attribute specific to the ng-include directive that functions as an ng-init. To see what I mean try something like:

<span onload="a = 1">{{ a }}</span>
<span ng-init="b = 2">{{ b }}</span>

You'll see that only the second one shows up.

An isolated scope is a scope which does not prototypically inherit from its parent scope. In laymen's terms if you have a widget that doesn't need to read and write to the parent scope arbitrarily then you use an isolate scope on the widget so that the widget and widget container can freely use their scopes without overriding each other's properties.

The file permission is okay (0777) but i think your on the shared server, so to delete your file correctly use; 1. create a correct path to your file

// delete from folder
$filename = 'test.txt';
$ifile = '/newy/made/link/uploads/'. $filename; // this is the actual path to the file you want to delete.
unlink($_SERVER['DOCUMENT_ROOT'] .$ifile); // use server document root
// your file will be removed from the folder

That small code will do the magic and remove any selected file you want from any folder provided the actual file path is collect.

As Brian asked:

empty_data appears to only set the field to 1 when it is submitted with no value. What about when you want the form to default to displaying 1 in the input when no value is present?

you can set the default value with empty_value

$builder->add('myField', 'number', ['empty_value' => 'Default value'])

Using JOIN makes the code easier to read, since it's self-explanatory.

There's no difference in speed(I have just tested it) and the execution plan is the same.

SELECT is_read_committed_snapshot_on FROM sys.databases 
WHERE name= 'YourDatabase'

Return value:

• 1: READ_COMMITTED_SNAPSHOT option is ON. Read operations under the READ COMMITTED isolation level are based on snapshot scans and do not acquire locks.
• 0 (default): READ_COMMITTED_SNAPSHOT option is OFF. Read operations under the READ COMMITTED isolation level use Shared (S) locks.

A scalar always holds a single element. Whatever is in a scalar variable is always a scalar. A reference is a scalar value.

If you want to know if it is a reference, you can use ref. If you want to know the reference type, you can use the reftype routine from Scalar::Util.

If you want to know if it is an object, you can use the blessed routine from Scalar::Util. You should never care what the blessed package is, though. UNIVERSAL has some methods to tell you about an object: if you want to check that it has the method you want to call, use can; if you want to see that it inherits from something, use isa; and if you want to see it the object handles a role, use DOES.

If you want to know if that scalar is actually just acting like a scalar but tied to a class, try tied. If you get an object, continue your checks.

If you want to know if it looks like a number, you can use looks_like_number from Scalar::Util. If it doesn't look like a number and it's not a reference, it's a string. However, all simple values can be strings.

If you need to do something more fancy, you can use a module such as Params::Validate.

Yes.

Private Sub MyForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Dim MyTextbox as New Textbox
    With MyTextbox
       .Size = New Size(100,20)
       .Location = New Point(20,20)
    End With
    AddHandler MyTextbox.TextChanged, AddressOf MyTextbox_Changed
    Me.Controls.Add(MyTextbox)

'Without a help environment for an intelli sense substitution

Add padding. Padding the element will increase the space between its content and its border. However, note that a box-shadow will begin outside the border, not the content, meaning you can't put space between the shadow and the box. Alternatively you could use :before or :after pseudo selectors on the element to create a slightly bigger box that you place the shadow on, like so: http://jsbin.com/aqemew/edit#source

Your question is: are these not modules capable of declaring variables at global scope?

Answer: YES, they are "capable"

The only point is that references to global variables in ThisWorkbook or a Sheet module have to be fully qualified (i.e., referred to as ThisWorkbook.Global1, e.g.) References to global variables in a standard module have to be fully qualified only in case of ambiguity (e.g., if there is more than one standard module defining a variable with name Global1, and you mean to use it in a third module).

For instance, place in Sheet1 code

Public glob_sh1 As String

Sub test_sh1()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

place in ThisWorkbook code

Public glob_this As String

Sub test_this()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

and in a Standard Module code

Public glob_mod As String

Sub test_mod()
    glob_mod = "glob_mod"
    ThisWorkbook.glob_this = "glob_this"
    Sheet1.glob_sh1 = "glob_sh1"
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

All three subs work fine.

PS1: This answer is based essentially on info from here. It is much worth reading (from the great Chip Pearson).

PS2: Your line Debug.Print ("Hello") will give you the compile error Invalid outside procedure.

PS3: You could (partly) check your code with Debug -> Compile VBAProject in the VB editor. All compile errors will pop.

PS4: Check also Put Excel-VBA code in module or sheet?.

PS5: You might be not able to declare a global variable in, say, Sheet1, and use it in code from other workbook (reading http://msdn.microsoft.com/en-us/library/office/gg264241%28v=office.15%29.aspx#sectionSection0; I did not test this point, so this issue is yet to be confirmed as such). But you do not mean to do that in your example, anyway.

PS6: There are several cases that lead to ambiguity in case of not fully qualifying global variables. You may tinker a little to find them. They are compile errors.

cPickle comes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle, you can do this:

>>> import _pickle as cPickle

However, in 3.x, it's easier just to use pickle.

No need to install anything. If something requires cPickle in python 3.x, then that's probably a bug.

I don't recall of a "indexOf" on arrays other than coding it for yourself... though you could probably use one of the many java.util.Arrays#binarySearch(...) methods (see the Arrays javadoc) if your array contains primitive types

String formattedStr=unformattedStr;
formattedStr=formattedStr.trim().replaceAll("\\s+", " ");

I had a similar problem. To solve this (instead of calculate the iframe's height using the body, document or window) I created a div that wraps the whole page content (a div with an id="page" for example) and then I used its height.

Try your code like this:

var app = express();
app.get('/test', function(req, res) {
    res.sendFile('views/test.html', {root: __dirname })
});

1. Use res.sendFile instead of reading the file manually so express can handle setting the content-type properly for you.

2. You don't need the app.engine line, as that is handled internally by express.

The easiest way is to use the library commands

import commands
print commands.getstatusoutput('echo "test" | wc')

Because your else isn't attached to anything. The if without braces only encompasses the single statement that immediately follows it.

if (choice==5)
{
    System.out.println("End of Game\n Thank you for playing with us!");
    break;
}
else
{
   System.out.println("Not a valid choice!\n Please try again...\n");
}

Not using braces is generally viewed as a bad practice because it can lead to the exact problems you encountered.

In addition, using a switch here would make more sense.

int choice;
boolean keepGoing = true;
while(keepGoing)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch(choice)
    {
        case 1: 
            playGame();
            break;
        case 2: 
            loadGame();
            break;
        // your other cases
        // ...
        case 5: 
            System.out.println("End of Game\n Thank you for playing with us!");
            keepGoing = false;
            break;
        default:
            System.out.println("Not a valid choice!\n Please try again...\n");
     }
 }         

Note that instead of an infinite for loop I used a while(boolean), making it easy to exit the loop. Another approach would be using break with labels.

Matplotlib does this by default.

E.g.:

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(10)

plt.plot(x, x)
plt.plot(x, 2 * x)
plt.plot(x, 3 * x)
plt.plot(x, 4 * x)
plt.show()

And, as you may already know, you can easily add a legend:

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(10)

plt.plot(x, x)
plt.plot(x, 2 * x)
plt.plot(x, 3 * x)
plt.plot(x, 4 * x)

plt.legend(['y = x', 'y = 2x', 'y = 3x', 'y = 4x'], loc='upper left')

plt.show()

If you want to control the colors that will be cycled through:

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(10)

plt.gca().set_color_cycle(['red', 'green', 'blue', 'yellow'])

plt.plot(x, x)
plt.plot(x, 2 * x)
plt.plot(x, 3 * x)
plt.plot(x, 4 * x)

plt.legend(['y = x', 'y = 2x', 'y = 3x', 'y = 4x'], loc='upper left')

plt.show()

If you're unfamiliar with matplotlib, the tutorial is a good place to start.

Edit:

First off, if you have a lot (>5) of things you want to plot on one figure, either:

1. Put them on different plots (consider using a few subplots on one figure), or
2. Use something other than color (i.e. marker styles or line thickness) to distinguish between them.

Otherwise, you're going to wind up with a very messy plot! Be nice to who ever is going to read whatever you're doing and don't try to cram 15 different things onto one figure!!

Beyond that, many people are colorblind to varying degrees, and distinguishing between numerous subtly different colors is difficult for more people than you may realize.

That having been said, if you really want to put 20 lines on one axis with 20 relatively distinct colors, here's one way to do it:

import matplotlib.pyplot as plt
import numpy as np

num_plots = 20

# Have a look at the colormaps here and decide which one you'd like:
# http://matplotlib.org/1.2.1/examples/pylab_examples/show_colormaps.html
colormap = plt.cm.gist_ncar
plt.gca().set_prop_cycle(plt.cycler('color', plt.cm.jet(np.linspace(0, 1, num_plots))))

# Plot several different functions...
x = np.arange(10)
labels = []
for i in range(1, num_plots + 1):
    plt.plot(x, i * x + 5 * i)
    labels.append(r'$y = %ix + %i$' % (i, 5*i))

# I'm basically just demonstrating several different legend options here...
plt.legend(labels, ncol=4, loc='upper center', 
           bbox_to_anchor=[0.5, 1.1], 
           columnspacing=1.0, labelspacing=0.0,
           handletextpad=0.0, handlelength=1.5,
           fancybox=True, shadow=True)

plt.show()

It's valid in C for historical reasons. C traditionally specified that the type of a string literal was char * rather than const char *, although it qualified it by saying that you're not actually allowed to modify it.

When you use a cast, you're essentially telling the compiler that you know better than the default type matching rules, and it makes the assignment OK.

Works fine by just adding the: [IgnoreDataMember]

On top of the propertyp, like:

public class UserSettingsModel
{
    public string UserName { get; set; }
    [IgnoreDataMember]
    public DateTime Created { get; set; }
}

This works with ApiController. The code:

[Route("api/Context/UserSettings")]
    [HttpGet, HttpPost]
    public UserSettingsModel UserSettings()
    {
        return _contextService.GetUserSettings();
    }

git reset <hash>  # you need to know the last good hash, so you can remove all your local commits

git fetch upstream
git checkout master
git merge upstream/master
git push origin master -f

voila, now your fork is back to same as upstream.

A variant of caf's answer: top -p <pid>

This auto-refreshes the CPU usage so it's good for monitoring.

It's just bcz your JS gets loaded before the HTML part and so it can't find that element. Just put your whole JS code inside a function which will be called when the window gets loaded.

You can also put your Javascript code below the html.

Its not possible to access any PHP function inside Twig directly.

What you can do is write a Twig extension. A common structure is, writing a service with some utility functions, write a Twig extension as bridge to access the service from twig. The Twig extension will use the service and your controller can use the service too.

Take a look: http://symfony.com/doc/current/cookbook/templating/twig_extension.html

Cheers.

$('#mytable tr').each(function() {
    var customerId = $(this).find("td:first").html();    
});

What you are doing is iterating through all the trs in the table, finding the first td in the current tr in the loop, and extracting its inner html.

To select a particular cell, you can reference them with an index:

$('#mytable tr').each(function() {
    var customerId = $(this).find("td").eq(2).html();    
});

In the above code, I will be retrieving the value of the third row (the index is zero-based, so the first cell index would be 0)

Here's how you can do it without jQuery:

var table = document.getElementById('mytable'), 
    rows = table.getElementsByTagName('tr'),
    i, j, cells, customerId;

In this case that you know that you have all items in the first place on array you can parse the string to JArray and then parse the first item using JObject.Parse

var  jsonArrayString = @"
[
  {
    ""country"": ""India"",
    ""city"": ""Mall Road, Gurgaon"",
  },
  {
    ""country"": ""India"",
    ""city"": ""Mall Road, Kanpur"",
  }
]";
JArray jsonArray = JArray.Parse(jsonArrayString);
dynamic data = JObject.Parse(jsonArray[0].ToString());

When waiting for lock on working directory, delete .hg/wlock.

Based on the accepted answer I created an Extension method as follows:

public static Guid ToGuid(this string aString)
{
    Guid newGuid;

    if (string.IsNullOrWhiteSpace(aString))
    {
        return MagicNumbers.defaultGuid;
    }

    if (Guid.TryParse(aString, out newGuid))
    {
        return newGuid;
    }

    return MagicNumbers.defaultGuid;
}

Where "MagicNumbers.defaultGuid" is just "an empty" all zero Guid "00000000-0000-0000-0000-000000000000".

In my case returning that value as the result of an invalid ToGuid conversion was not a problem.

You should be able to read the GUID attribute of the assembly via reflection. This will get the GUID for the current assembly

Assembly asm = Assembly.GetExecutingAssembly();
var attribs = (asm.GetCustomAttributes(typeof(GuidAttribute), true));
Console.WriteLine((attribs[0] as GuidAttribute).Value);

You can replace the GuidAttribute with other attributes as well, if you want to read things like AssemblyTitle, AssemblyVersion, etc.

You can also load another assembly (Assembly.LoadFrom and all) instead of getting the current assembly - if you need to read these attributes of external assemblies (for example, when loading a plugin).

What about wrapping your call in a Promise.all() method i.e.

Promise.all([$http.get(url).then(function(result){....}, function(error){....}])

According to MDN

Promise.all waits for all fulfillments (or the first rejection)

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

You'll need different sized icons for iOS and Android, like Rockvic said. In addition, I recommend this site for generating different sized icons if anybody is interested. You don't need to download anything and it works perfectly.

Hope it helps.

The LINQ solution:

Dns.GetHostEntry(Dns.GetHostName()).AddressList.Where(ip => ip.AddressFamily == AddressFamily.InterNetwork).Select(ip => ip.ToString()).FirstOrDefault() ?? ""

To trigger an event you basically just call the event handler for that element. Slight change from your code.

var a = document.getElementById("element");
var evnt = a["onclick"];

if (typeof(evnt) == "function") {
    evnt.call(a);
}

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

I usually do this in the thread handling the json response:

try {
  Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageUrl).getContent());
} catch (MalformedURLException e) {
  e.printStackTrace();
} catch (IOException e) {
  e.printStackTrace();
}

If you need to do transformations on the image, you'll want to create a Drawable instead of a Bitmap.

If you have not yet pushed or otherwise shared your commit:

git diff --stat HEAD^...HEAD | \
fgrep filename_snippet_to_revert | cut -d' ' -f2 | xargs git checkout HEAD^ --
git commit -a --amend

You can switch to manual build so can control when this is done. Just make sure that Project > Build Automatically from the main menu is unchecked.

If you are working on windows, you can use pywin32 (old link: see update below).

I found an example here:

import win32com.client

wmi = win32com.client.GetObject ("winmgmts:")
for usb in wmi.InstancesOf ("Win32_USBHub"):
    print usb.DeviceID

Update Apr 2020:

'pywin32' release versions from 218 and up can be found here at github. Current version 227.

Tuples are available since .NET4.0 and support generics:

Tuple<string, int> t = new Tuple<string, int>("Hello", 4);

In previous versions you can use System.Collections.Generic.KeyValuePair<K, V> or a solution like the following:

public class Pair<T, U> {
    public Pair() {
    }

    public Pair(T first, U second) {
        this.First = first;
        this.Second = second;
    }

    public T First { get; set; }
    public U Second { get; set; }
};

And use it like this:

Pair<String, int> pair = new Pair<String, int>("test", 2);
Console.WriteLine(pair.First);
Console.WriteLine(pair.Second);

This outputs:

test
2

Or even this chained pairs:

Pair<Pair<String, int>, bool> pair = new Pair<Pair<String, int>, bool>();
pair.First = new Pair<String, int>();
pair.First.First = "test";
pair.First.Second = 12;
pair.Second = true;

Console.WriteLine(pair.First.First);
Console.WriteLine(pair.First.Second);
Console.WriteLine(pair.Second);

That outputs:

test
12
true

Why are you including the getClassLoader step? If you say "this.getClass().getResource()" you should be getting resources relative to the calling class. I've never used ClassLoader.getResource(), though from a quick look at the Java Docs it sounds like that will get you the first resource of that name found in any current classpath.

Sometimes the interest is in knowing the number of messages in each partition, for example, when testing a custom partitioner.The ensuing steps have been tested to work with Kafka 0.10.2.1-2 from Confluent 3.2. Given a Kafka topic, kt and the following command-line:

$ kafka-run-class kafka.tools.GetOffsetShell \
  --broker-list host01:9092,host02:9092,host02:9092 --topic kt

That prints the sample output showing the count of messages in the three partitions:

kt:2:6138
kt:1:6123
kt:0:6137

The number of lines could be more or less depending on the number of partitions for the topic.

The align-items property of flex-box aligns the items inside a flex container along the cross axis just like justify-content does along the main axis. (For the default flex-direction: row the cross axis corresponds to vertical and the main axis corresponds to horizontal. With flex-direction: column those two are interchanged respectively).

Here's an example of how align-items:center looks:

But align-content is for multi line flexible boxes. It has no effect when items are in a single line. It aligns the whole structure according to its value. Here's an example for align-content: space-around;:

And here's how align-content: space-around; with align-items:center looks:

Note the 3rd box and all other boxes in first line change to vertically centered in that line.

Here's a super cool pen which shows and lets you play with almost everything in flexbox.

Uses Line Feeds and spaces as a good break point:

declare @sqlAll as nvarchar(max)
set @sqlAll = '-- Insert all your sql here'

print '@sqlAll - truncated over 4000'
print @sqlAll
print '   '
print '   '
print '   '

print '@sqlAll - split into chunks'
declare @i int = 1, @nextspace int = 0, @newline nchar(2)
set @newline = nchar(13) + nchar(10)


while Exists(Select(Substring(@sqlAll,@i,3000))) and (@i < LEN(@sqlAll))
begin
    while Substring(@sqlAll,@i+3000+@nextspace,1) <> ' ' and Substring(@sqlAll,@i+3000+@nextspace,1) <> @newline
    BEGIN
        set @nextspace = @nextspace + 1
    end
    print Substring(@sqlAll,@i,3000+@nextspace)
    set @i = @i+3000+@nextspace
    set @nextspace = 0
end
print '   '
print '   '
print '   '
