Here is what i observed when I used my own image sets in .jpg format. In the sample script available in Opencv doc, note that it has the undistort and crop the image lines as below:

# undistort
dst = cv2.undistort(img, mtx, dist, None, newcameramtx)

# crop the image
x,y,w,h = roi
dst = dst[y:y+h, x:x+w]
cv2.imwrite('calibresult.jpg',dst)

So, when we run the code for the first time, it executes the line cv2.imwrite('calibresult.jpg',dst) saving a image calibresult.jpg in the current directory. So, when I ran the code for the next time, along with my sample image sets that I used for calibrating the camera in jpg format, the code also tried to consider this newly added image calibresult.jpg due to which the error popped out

error: C:\builds\master_PackSlaveAddon-win64-vc12-static\opencv\modules\imgproc\src\color.cpp:7456: error: (-215) scn == 3 || scn == 4 in function cv::ipp_cvtColor

What I did was: I simply deleted that newly generated image after each run or alternatively changed the type of the image to say png or tiff type. That solved the problem. Check if you are inputting and writing calibresult of the same type. If so, just change the type.

For everyone stumbling upon this post because pandas gets mentioned, you now have the very elegant and straighforward option of directly accessing the secondary_y axis in pandas with ax.right_ax

So paraphrasing the example initially posted, you would write:

table = sql.read_frame(query,connection)

ax = table[[0, 1]].plot(ylim=(0,100), secondary_y=table[1])
ax.set_ylabel('$')
ax.right_ax.set_ylabel('Your second Y-Axis Label goes here!')

(this is already mentioned in these posts as well: 1 2)

For me what works here is to using a version manager such as pyenv, which I strongly recommend to get your project environments and package versions well managed and separate from that of the operative system.

I had this same error after an OS update, but was easily fixed with pyenv install 3.7-dev (the version I use).

One datestamp is already in the _id object, representing insert time

So if the insert time is what you need, it's already there:

switched to db penguins

Get the rows back:

If that last one-liner confuses you I have a walkthrough on how that works here: https://stackoverflow.com/a/27613766/445131

If you want you can achieve this using a CLR Function/Assembly.

1. Create a SQL Server CLR Assembly Project.
2. Go to properties and ensure the permission level on the Connection is setup to external
3. Add A Sql Function to the Assembly.

Here's an example which will allow you to select form your result set like a table.

public partial class UserDefinedFunctions
{
    [SqlFunction(DataAccess = DataAccessKind.Read,
        FillRowMethodName = "GetFiles_FillRow", TableDefinition = "FilePath nvarchar(4000)")]
    public static IEnumerable GetFiles(SqlString path)
    {
        return System.IO.Directory.GetFiles(path.ToString()).Select(s => new SqlString(s));
    }

    public static void GetFiles_FillRow(object obj,out SqlString filePath)
    {
        filePath = (SqlString)obj;
    }
};

And your SQL query.

use MyDb

select * From GetFiles('C:\Temp\');

Be aware though, your database needs to have CLR Assembly functionaliy enabled using the following SQL Command.

sp_configure 'clr enabled', 1
GO
RECONFIGURE
GO

CLR Assemblies (like XP_CMDShell) are disabled by default so if the reason for not using XP Cmd Shell is because you don't have permission, then you may be stuck with this option as well... just FYI.

You don't import scripts in Python you import modules. Some python modules are also scripts that you can run directly (they do some useful work at a module-level).

In general it is preferable to use absolute imports rather than relative imports.

toplevel_package/
+-- __init__.py
+-- moduleA.py
+-- subpackage
    +-- __init__.py
    +-- moduleB.py

In moduleB:

from toplevel_package import moduleA

If you'd like to run moduleB.py as a script then make sure that parent directory for toplevel_package is in your sys.path.

Rather than using JavaScript perhaps try something like

<a href="#">

  <input type="submit" value="save" style="background: transparent none; border: 0px none; text-decoration: inherit; color: inherit; cursor: inherit" />

</a>

A primary key defines a unique identifier for every row in a table: when a table has a primary key, you have a guranteed way to select any row from it.

A unique constraint does not necessarily identify every row; it just specifies that if a row has values in its columns, then they must be unique. This is not sufficient to uniquely identify every row, which is what a primary key must do.

This goes back to the basic difference between & and &&, | and ||

BTW you perform the same tasks many times. Not sure if efficiency is an issue. You could remove some of the duplication.

Z z2 = partialHits.get(req_nr).get(z); // assuming a value cannout be null.
Z z3 = tmpmap.get(z); // assuming z3 cannot be null.
if(z2 == null || z2 < z3){   
    partialHits.get(z).put(z, z3);   
} 

Use method=POST then it will pass key&value.

You could also strip all the non-digit characters (\D or [^0-9]):

let word_With_Numbers = 'abc123c def4567hij89'_x000D_
let word_Without_Numbers = word_With_Numbers.replace(/\D/g, '');_x000D_
_x000D_
console.log(word_Without_Numbers)

Coming to this late in the day but here is my pennyworth with an object that just happens to hold some useful paths in an app but you can adapt it for anything where you want a sorta dict of information that you can access with getattr and dot notation (which is what I think this question is really about):

import os

def x_path(path_name):
    return getattr(x_path, path_name)

x_path.root = '/home/x'
for name in ['repository', 'caches', 'projects']:
    setattr(x_path, name, os.path.join(x_path.root, name))

This is cool because now:

In [1]: x_path.projects
Out[1]: '/home/x/projects'

In [2]: x_path('caches')
Out[2]: '/home/x/caches'

So this uses the function object like the above answers but uses the function to get the values (you can still use (getattr, x_path, 'repository') rather than x_path('repository') if you prefer).

use js split() method to create an array

var keywords = $('#searchKeywords').val().split(",");

then loop through the array using jQuery.each() function. as the documentation says:

In the case of an array, the callback is passed an array index and a corresponding array value each time

$.each(keywords, function(i, keyword){
   console.log(keyword);
});

Re-review the Android Activity Lifecycle reference. There is a nice picture, and the table showing what methods get called. reference Link google

https://developer.android.com/reference/android/app/Activity.html

You can use the shorthand flex property and set it to

flex: 0 0 100%;

That's flex-grow, flex-shrink, and flex-basis in one line. Flex shrink was described above, flex grow is the opposite, and flex basis is the size of the container.

In a Python 2 program that I used for many years there was this line:

ocd[i].namn=unicode(a[:b], 'utf-8')

This did not work in Python 3.

However, the program turned out to work with:

ocd[i].namn=a[:b]

I don't remember why I put unicode there in the first place, but I think it was because the name can contains Swedish letters åäöÅÄÖ. But even they work without "unicode".

If you don't mind the set to be sorted then you may be interested to take a look at the indexed-tree-map project.

The enhanced TreeSet/TreeMap provides access to elements by index or getting the index of an element. And the implementation is based on updating node weights in the RB tree. So no iteration or backing up by a list here.

Below worked for me.

Height & width are taken to show that, if you 2 such children, it will scroll horizontally, since height of child is greater than height of parent scroll vertically.

Parent CSS:

.divParentClass {
    width: 200px;
    height: 100px;
    overflow: scroll;
    white-space: nowrap;
}

Children CSS:

.divChildClass {
    width: 110px;
    height: 200px;
    display: inline-block;
}

To scroll horizontally only:

overflow-x: scroll;
overflow-y: hidden;

To scroll vertically only:

overflow-x: hidden;
overflow-y: scroll;

Yes. But you can't redefine built-in types. You have to subclass them:

class MyTuple(tuple):
    def __add__(self, other):
         if len(self) != len(other):
             raise ValueError("tuple lengths don't match")
         return MyTuple(x + y for (x, y) in zip(self, other))

Addition to accepted answer -

If password not seen in logs, enable "org.springframework.boot.autoconfigure.security" logs.

If you fine-tune your logging configuration, ensure that the org.springframework.boot.autoconfigure.security category is set to log INFO messages, otherwise the default password will not be printed.

To Calculate age from Date of birth used used query like this.

'SELECT username, email, skype, avatar, TIMESTAMPDIFF(YEAR, date, CURDATE()) AS age, signup_date, gender FROM users WHERE id="'.$id.'"';


if(isset($_GET['id']))
{
    $id = intval($_GET['id']);

    $dn = mysql_query('select username, email, skype, avatar, TIMESTAMPDIFF(YEAR, date, CURDATE()) AS age, signup_date, gender from users where id="'.$id.'"');

    $dnn = mysql_fetch_array($dn);

    echo $dnn['age'];
}

Note: don't use reserved keywords column name.

Use This Query :

Select
    S.name + '.' + T.name As TableName ,
    SUM( P.rows ) As RowCont 

From sys.tables As T
    Inner Join sys.partitions As P On ( P.OBJECT_ID = T.OBJECT_ID )
    Inner Join sys.schemas As S On ( T.schema_id = S.schema_id )
Where
    ( T.is_ms_shipped = 0 )
    AND 
    ( P.index_id IN (1,0) )
    And
    ( T.type = 'U' )

Group By S.name , T.name 

Order By SUM( P.rows ) Desc

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

The following should do the trick - Only SqlServer

Alter TRIGGER Catagory_Master_Date_update ON Catagory_Master AFTER delete,Update
AS
BEGIN

SET NOCOUNT ON;

Declare @id int
DECLARE @cDate as DateTime
    set @cDate =(select Getdate())

select @id=deleted.Catagory_id from deleted
print @cDate

execute dbo.psp_Update_Category @id

END

Alter PROCEDURE dbo.psp_Update_Category
@id int
AS
BEGIN

DECLARE @cDate as DateTime
    set @cDate =(select Getdate())
    --Update Catagory_Master Set Modify_date=''+@cDate+'' Where Catagory_ID=@id   --@UserID
    Insert into Catagory_Master (Catagory_id,Catagory_Name) values(12,'Testing11')
END 

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

You typically restore purchases with this code:

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

It will reinvoke -paymentQueue:updatedTransactions on the observer(s) for the purchased items. This is useful for users who reinstall the app after deletion or install it on a different device.

Not all types of In-App purchases can be restored.

Sorry EMS, but I actually just got another response from the matplotlib mailling list (Thanks goes out to Benjamin Root).

The code I am looking for is adjusting the savefig call to:

fig.savefig('samplefigure', bbox_extra_artists=(lgd,), bbox_inches='tight')
#Note that the bbox_extra_artists must be an iterable

This is apparently similar to calling tight_layout, but instead you allow savefig to consider extra artists in the calculation. This did in fact resize the figure box as desired.

import matplotlib.pyplot as plt
import numpy as np

plt.gcf().clear()
x = np.arange(-2*np.pi, 2*np.pi, 0.1)
fig = plt.figure(1)
ax = fig.add_subplot(111)
ax.plot(x, np.sin(x), label='Sine')
ax.plot(x, np.cos(x), label='Cosine')
ax.plot(x, np.arctan(x), label='Inverse tan')
handles, labels = ax.get_legend_handles_labels()
lgd = ax.legend(handles, labels, loc='upper center', bbox_to_anchor=(0.5,-0.1))
text = ax.text(-0.2,1.05, "Aribitrary text", transform=ax.transAxes)
ax.set_title("Trigonometry")
ax.grid('on')
fig.savefig('samplefigure', bbox_extra_artists=(lgd,text), bbox_inches='tight')

This produces:

[edit] The intent of this question was to completely avoid the use of arbitrary coordinate placements of arbitrary text as was the traditional solution to these problems. Despite this, numerous edits recently have insisted on putting these in, often in ways that led to the code raising an error. I have now fixed the issues and tidied the arbitrary text to show how these are also considered within the bbox_extra_artists algorithm.

Has your problem been resolved? What is your target SDK? Try adding android;maxSDKVersion="21" to <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

I use both Clang and GCC, I find Clang has some useful warnings, but for my own ray-tracing benchmarks - its consistently 5-15% slower then GCC (take that with grain of salt of course, but attempted to use similar optimization flags for both).

So for now I use Clang static analysis and its warnings with complex macros: (though now GCC's warnings are pretty much as good - gcc4.8 - 4.9).

Some considerations:

• Clang has no OpenMP support, only matters if you take advantage of that but since I do, its a limitation for me. (*****)
• Cross compilation may not be as well supported (FreeBSD 10 for example still use GCC4.x for ARM), gcc-mingw for example is available on Linux... (YMMV).
• Some IDE's don't yet support parsing Clangs output (QtCreator for example *****). EDIT: QtCreator now supports Clang's output
• Some aspects of GCC are better documented and since GCC has been around for longer and is widely used, you might find it easier to get help with warnings / error messages.

***** - these areas are in active development and may soon be supported

To get only empty values (and not null values):

SELECT * FROM myTable WHERE myColumn = ''

To get both null and empty values:

SELECT * FROM myTable WHERE myColumn IS NULL OR myColumn = ''

To get only null values:

SELECT * FROM myTable WHERE myColumn IS NULL

To get values other than null and empty:

SELECT * FROM myTable WHERE myColumn <> ''

And remember use LIKE phrases only when necessary because they will degrade performance compared to other types of searches.

I recommend dynamically adding the elements, and if using jQuery or other JavaScript library, it is quite simple:

• http://api.jquery.com/appendTo/
• http://api.jquery.com/prependTo/
• http://api.jquery.com/html/

also look at prepend and append. Otherwise if you have an image tag like that, and you want to make it validate, then you might consider using a dummy image, such as a 1px transparent gif or png.

A slightly different solution is to use the special variable ansible_limit which is the contents of the --limit CLI option for the current execution of Ansible.

- hosts: "{{ ansible_limit | default(omit) }}"

No need to define an extra variable here, just run the playbook with the --limit flag.

ansible-playbook --limit imac-2.local user.yml

You can use the spread operator on the keys of a freshly created array.

[...Array(n).keys()]

or

Array.from(Array(n).keys())

The Array.from() syntax is necessary if working with TypeScript

This can be achieved using the POSIX clock_gettime function.

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

Here is an example of how to use clock_gettime:

#define _POSIX_C_SOURCE 200809L

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

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

    clock_gettime(CLOCK_REALTIME, &spec);

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

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

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

                        used.  For "@=" you are prompted to enter an
                        expression.  The result of the expression is then
                        executed.  See also |@:|.  {Vi: only named registers}

atoi can do that for you

Example:

char string[] = "1234";
int sum = atoi( string );
printf("Sum = %d\n", sum ); // Outputs: Sum = 1234

When looking for the max performance you run into a lot of issue and potential bottlenecks. Running a simple hello world test is not necessarily going to find them all.

Possible limitations include:

• Kernel socket limitations: look in /proc/sys/net for lots of kernel tuning..
• process limits: check out ulimit as others have stated here
• as your application grows in complexity, it may not have enough CPU power to keep up with the number of connections coming in. Use top to see if your CPU is maxed
• number of threads? I'm not experienced with threading, but this may come into play in conjunction with the previous items.

Note: This answer is related to the question "How to turn off echo while executing a shell script Linux" which was in turn marked as duplicated to this one.

To actually turn off the echo the command is:

stty -echo

(this is, for instance; when you want to enter a password and you don't want it to be readable. Remember to turn echo on at the end of your script, otherwise the person that runs your script won't see what he/she types in from then on. To turn echo on run:

stty echo

I know there are a lot of answers to this already but I would like to put in my two cents. When creating a virtual environment in anaconda launcher you still need to install the packages you need. This is deceiving because I assumed since I was using anaconda that packages such as pandas, numpy etc would be include. This is not the case. It gives you a fresh environment with none of those packages installed, at least mine did. All my packages installed into the environment with no problem and work correctly.

To avoid common mistakes when using exclude, remember:

You can not add multiple conditions into an exclude() block like filter. To exclude multiple conditions, you must use multiple exclude()

Example

Incorrect:

User.objects.filter(email='[email protected]').exclude(profile__nick_name='', profile__avt='')

Correct:

User.objects.filter(email='[email protected]').exclude(profile__nick_name='').exclude(profile__avt='')

you can use $ (jquery) :

<div>
    <form role="form" class="form-horizontal ">        
        <div [ngClass]="{showElement:IsEditMode, hidden:!IsEditMode}">
            <div class="form-group">
                <label class="control-label col-md-1 col-sm-1" for="name">Name</label>
                <div class="col-md-7 col-sm-7">
                    <input id="txtname`enter code here`" type="text" [(ngModel)]="person.Name" class="form-control" />

                </div>
                <div class="col-md-2 col-sm-2">
                    <input type="button" value="Add" (click)="AddPerson()" class="btn btn-primary" />
                </div>
            </div>
        </div>
        <div [ngClass]="{showElement:!IsEditMode, hidden:IsEditMode}">
            <div class="form-group">
                <label class="control-label col-md-1 col-sm-1" for="name">Person</label>
                <div class="col-md-7 col-sm-7">
                    <select [(ngModel)]="SelectedPerson.Id"  (change)="PersonSelected($event.target.value)" class="form-control">
                        <option *ngFor="#item of PeopleList" value="{{item.Id}}">{{item.Name}}</option>
                    </select>
                </div>
            </div>
        </div>        
    </form>
</div>

then in ts :

    declare var $: any;

    @Component({
      selector: 'app-my-comp',
      templateUrl: './my-comp.component.html',
      styleUrls: ['./my-comp.component.css']
    })
    export class MyComponent  {

    @ViewChild('loadedComponent', { read: ElementRef, static: true }) loadedComponent: ElementRef<HTMLElement>;

    setFocus() {
    const elem = this.loadedComponent.nativeElement.querySelector('#txtname');
          $(elem).focus();
    }
    }

Please follow the below steps.

begin
  for i in (select 'drop table '||table_name||' cascade constraints' tb from user_tables) 
  loop
     execute immediate i.tb;
  end loop;
  commit;
end;
purge RECYCLEBIN;

Your command is right, but the error shows that you didn't create your ssh key yet. To generate new ssh key enter the following command into the terminal.

ssh-keygen

After entering the command then you will be asked to enter file name and passphrase. Normally you don't need to change this. Just press enter. Then your key will be generated in ~/.ssh directory. After this, you can copy your key by the following command.

pbcopy < ~/.ssh/id_rsa.pub 

or

cat .ssh/id_rsa.pub | pbcopy

You can find more about this here ssh.

Why am I unable to use a string for a newline in write() but I can use it in writelines()?

The idea is the following: if you want to write a single string you can do this with write(). If you have a sequence of strings you can write them all using writelines().

write(arg) expects a string as argument and writes it to the file. If you provide a list of strings, it will raise an exception (by the way, show errors to us!).

writelines(arg) expects an iterable as argument (an iterable object can be a tuple, a list, a string, or an iterator in the most general sense). Each item contained in the iterator is expected to be a string. A tuple of strings is what you provided, so things worked.

The nature of the string(s) does not matter to both of the functions, i.e. they just write to the file whatever you provide them. The interesting part is that writelines() does not add newline characters on its own, so the method name can actually be quite confusing. It actually behaves like an imaginary method called write_all_of_these_strings(sequence).

What follows is an idiomatic way in Python to write a list of strings to a file while keeping each string in its own line:

lines = ['line1', 'line2']
with open('filename.txt', 'w') as f:
    f.write('\n'.join(lines))

This takes care of closing the file for you. The construct '\n'.join(lines) concatenates (connects) the strings in the list lines and uses the character '\n' as glue. It is more efficient than using the + operator.

Starting from the same lines sequence, ending up with the same output, but using writelines():

lines = ['line1', 'line2']
with open('filename.txt', 'w') as f:
    f.writelines("%s\n" % l for l in lines)

This makes use of a generator expression and dynamically creates newline-terminated strings. writelines() iterates over this sequence of strings and writes every item.

Edit: Another point you should be aware of:

write() and readlines() existed before writelines() was introduced. writelines() was introduced later as a counterpart of readlines(), so that one could easily write the file content that was just read via readlines():

outfile.writelines(infile.readlines())

Really, this is the main reason why writelines has such a confusing name. Also, today, we do not really want to use this method anymore. readlines() reads the entire file to the memory of your machine before writelines() starts to write the data. First of all, this may waste time. Why not start writing parts of data while reading other parts? But, most importantly, this approach can be very memory consuming. In an extreme scenario, where the input file is larger than the memory of your machine, this approach won't even work. The solution to this problem is to use iterators only. A working example:

with open('inputfile') as infile:
    with open('outputfile') as outfile:
        for line in infile:
            outfile.write(line)

This reads the input file line by line. As soon as one line is read, this line is written to the output file. Schematically spoken, there always is only one single line in memory (compared to the entire file content being in memory in case of the readlines/writelines approach).

Update with Spring Boot 2.2.2.Release.

Full example here, https://www.surasint.com/spring-boot-override-property-example/

Assume that, in your jar file, you have the application.properties which have these two line:

server.servlet.context-path=/test
server.port=8081

Then, in production, you want to override the server.port=8888 but you don't want to override the other properties.

First you create another file, ex override.properties and have online this line:

server.port=8888

Then you can start the jar like this

java -jar spring-boot-1.0-SNAPSHOT.jar --spring.config.location=classpath:application.properties,/opt/somewhere/override.properties

Try this, it work for me

DECLARE @spname sysname;
DECLARE SPCursor CURSOR FOR
SELECT SCHEMA_NAME(schema_id) + '.' + name
FROM sys.objects
WHERE type = 'P';
OPEN SPCursor;
FETCH NEXT FROM SPCursor INTO @spname;
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC('DROP PROCEDURE ' + @spname);
FETCH NEXT FROM SPCursor INTO @spname;
END
CLOSE SPCursor;
DEALLOCATE SPCursor;

All I had to do was to install this

npm install @angular/animations@latest --save  

and then import

import { BrowserAnimationsModule } from '@angular/platform-browser/animations'; 

into your app.module.ts file.

1. Right click on your Project in the project explorer
2. Click on properties
3. Click on Run
4. Make sure your Main Class is the one you want to be the entry point. (Make sure to use the fully qualified name i.e. mypackage.MyClass)
5. Click OK.
6. Clean an build your project
7. Run Project :)

If you just want to run the file, right click on the class from the package explorer, and click Run File, or (Alt + R, F), or (Shift + F6)

Use below code to convert String Date to Epoc Timestamp. Note : - Your input Date format should match with SimpleDateFormat.

String inputDateInString= "8/15/2017 12:00:00 AM";
SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyy hh:mm:ss");

Date parsedDate = dateFormat.parse("inputDateInString");

Timestamp timestamp = new java.sql.Timestamp(parsedDate.getTime());

System.out.println("Timestamp "+ timestamp.getTime());

Add a CommandName attribute, and optionally a CommandArgument attribute, to your LinkButton control. Then set the OnCommand attribute to the name of your Command event handler.

<asp:LinkButton ID="ENameLinkBtn" runat="server" CommandName="MyValueGoesHere" CommandArgument="OtherValueHere" 
          style="font-weight: 700; font-size: 8pt;" OnCommand="ENameLinkBtn_Command" ><%# Eval("EName") %></asp:LinkButton>

<asp:Label id="Label1" runat="server"/>

Then it will be available when in your handler:

protected void ENameLinkBtn_Command (object sender, CommandEventArgs e)
{
   Label1.Text = "You chose: " + e.CommandName + " Item " + e.CommandArgument;
}

Select the tableview in your storyboard and ensure that the style is set to "Plain", instead of "Grouped". You can find this setting in the attributes Inspector tab.

I was having alot of trouble with this because I was using:

if($.cookie('token') === null || $.cookie('token') === "")
{
      //no cookie
}
else
{
     //have cookie
}

The above was ALWAYS returning false, no matter what I did in terms of setting the cookie or not. From my tests it seems that the object is therefore undefined before it's set so adding the following to my code fixed it.

if($.cookie('token') === null || $.cookie('token') === "" 
    || $.(cookie('token') === "null" || $.cookie('token') === undefined)
{
      //no cookie
}
else
{
     //have cookie
}

I just made an imageCrop and Upload feature with

https://www.npmjs.com/package/react-image-crop

to get the ImagePreview ( the cropped image rendering in a canvas)

https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob

canvas.toBlob(function(blob){...}, 'image/jpeg', 0.95);

I prefer sending data in blob with content type image/jpeg rather than toDataURL ( a huge base64 string`

My implementation for uploading to Azure Blob using SAS URL

axios.post(azure_sas_url, image_in_blob, {
   headers: {
      'x-ms-blob-type': 'BlockBlob',
      'Content-Type': 'image/jpeg'
   }
})

Null means nothing. Its just a literal. Null is the value of reference variable. But empty string is blank.It gives the length=0. Empty string is a blank value,means the string does not have any thing.

I found the game library Allegro easy to use back in the day. Might be worth a look.

in the html code only, add a panel that contains the page's controls. Inside the panel, add a line DefaultButton = "buttonNameThatClicksAtEnter". See the example below, there should be nothing else required.

<asp:Panel runat="server" DefaultButton="Button1"> //add this!
  //here goes all the page controls and the trigger button
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Send" />
</asp:Panel> //and this too!

How to get tables

1. SHOW TABLES

mysql> USE test;
Database changed
mysql> SHOW TABLES;
+----------------+
| Tables_in_test |
+----------------+
| t1             |
| t2             |
| t3             |
+----------------+
3 rows in set (0.00 sec)

2. SHOW TABLES IN db_name

mysql> SHOW TABLES IN another_db;
+----------------------+
| Tables_in_another_db |
+----------------------+
| t3                   |
| t4                   |
| t5                   |
+----------------------+
3 rows in set (0.00 sec)

3. Using information schema

mysql> SELECT TABLE_NAME
       FROM information_schema.TABLES
       WHERE TABLE_SCHEMA = 'another_db';
+------------+
| TABLE_NAME |
+------------+
| t3         |
| t4         |
| t5         |
+------------+
3 rows in set (0.02 sec)

to OP

you have fetched just 1 row. fix like this:

while ( $tables = $result->fetch_array())
{
    echo $tmp[0]."<br>";
}

and I think, information_schema would be better than SHOW TABLES

SELECT TABLE_NAME
FROM information_schema.TABLES 
WHERE TABLE_SCHEMA = 'your database name'

while ( $tables = $result->fetch_assoc())
{
    echo $tables['TABLE_NAME']."<br>";
}

Look for any loops or statements are left unclosed.

I had ran into this trouble when I left a php foreach: tag unclosed.

<?php foreach($many as $one): ?>

Closing it using the following solved the syntax error: unexpected end of file

<?php endforeach; ?>

Hope it helps someone

As mentioned above, be sure that you don't set any id fields which are supposed to be auto-generated.

To cause this problem during testing, make sure that the db 'sees' aka flush this SQL, otherwise everything may seem fine when really its not.

I encountered this problem when inserting my parent with a child into the db:

1. Insert parent (with manual ID)
2. Insert child (with autogenerated ID)
3. Update foreign key in Child table to parent.

The 3. statement failed. Indeed the entry with the autogenerated ID (by Hibernate) was not in the table as a trigger changed the ID upon each insertion, thus letting the update fail with no matching row found.

Since the table can be updated without any Hibernate I added a check whether the ID is null and only fill it in then to the trigger.

Your code won't work because you haven't assigned anything to n before you first use it. Try this:

def oracle():
    n = None
    while n != 'Correct':
        # etc...

A more readable approach is to move the test until later and use a break:

def oracle():
    guess = 50

    while True:
        print 'Current number = {0}'.format(guess)
        n = raw_input("lower, higher or stop?: ")
        if n == 'stop':
            break
        # etc...

Also input in Python 2.x reads a line of input and then evaluates it. You want to use raw_input.

Note: In Python 3.x, raw_input has been renamed to input and the old input method no longer exists.

while true ; do
    ...
    if [ something ]; then
        break
    fi
done

I am using Mac OS X 10.10 also. And to fix this problem.

1. Open Android Studio application package content (by right click on Android Studio icon in Application folder)
2. Open file Infor.plist

3. Search and replace:

   <key> JVM version</key>
   <string>1.6*</string>
   

replaced by:

    <key> JVM version</key>
    <string>1.6+</string>

That's it!

Slight change to @rejesh-yadav wonderful answer.

html2canvas now returns a promise.

html2canvas(document.body).then(function (canvas) {
    var img = canvas.toDataURL("image/png");
    var doc = new jsPDF();
    doc.addImage(img, 'JPEG', 10, 10);
    doc.save('test.pdf');        
});

Hope this helps some!

This code will work with Swift 3.0

class GradientView: UIView {

    override open class var layerClass: AnyClass {
        get{
            return CAGradientLayer.classForCoder()
        }
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        let gradientLayer = self.layer as! CAGradientLayer
        let color1 = UIColor.white.withAlphaComponent(0.1).cgColor as CGColor
        let color2 = UIColor.white.withAlphaComponent(0.9).cgColor as CGColor
        gradientLayer.locations = [0.60, 1.0]
        gradientLayer.colors = [color2, color1]
    }
}

You can get the nodeValue of the first childNode using

$('.title')[0].childNodes[0].nodeValue

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

Not possible. How is the Map supposed to know which subclass of Animal it's going to get, given only a String key?

The only way this would be possible is if each Animal accepted only one type of friend (then it could be a parameter of the Animal class), or of the callFriend() method got a type parameter. But it really looks like you're missing the point of inheritance: it's that you can only treat subclasses uniformly when using exclusively the superclass methods.

Multi-word (and multi-line) cursors/selection in VS Code

Multi-word:

Windows / OS X:

• Ctrl+Shift+L / ?+Shift+L selects all instances of the current highlighted word
• Ctrl+D / ?+D selects the next instance... and the one after that... etc.

Multi-line:

For multi-line selection, Ctrl+Alt+Down / ?+Alt+Shift+Down will extend your selection or cursor position to the next line. Ctrl+Right / ?+Right will move to the end of each line, no matter how long. To escape the multi-line selection, hit Esc.

See the VS Code keybindings (OS sensitive)

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

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

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

Lots of outdated answers to this question. As of Swift 2+ the Swift Standard Library contains the readline() function. It will return an Optional but it will only be nil if EOF has been reached, which will not happen when getting input from the keyboard so it can safely be unwrapped by force in those scenarios. If the user does not enter anything its (unwrapped) value will be an empty string. Here's a small utility function that uses recursion to prompt the user until at least one character has been entered:

func prompt(message: String) -> String {
    print(message)
    let input: String = readLine()!
    if input == "" {
        return prompt(message: message)
    } else {
        return input
    }
}

let input = prompt(message: "Enter something!")
print("You entered \(input)")

Note that using optional binding (if let input = readLine()) to check if something was entered as proposed in other answers will not have the desired effect, as it will never be nil and at least "" when accepting keyboard input.

This will not work in a Playground or any other environment where you does not have access to the command prompt. It seems to have issues in the command-line REPL as well.

Under a Linux environment you could do the following :

$ find <base_dir> -name *.jar -print0 | xargs -0 -l jar tf | grep <name>

Where name is the name of the class file that you are looking inside the jars distributed across the hierarchy of directories rooted at the base_dir.

import com.google.common.collect.ComparisonChain;

/**
 * @author radler
 * Class Description ...
 */
public class Attribute implements Comparable<Attribute> {

    private String type;
    private String value;

    public String getType() { return type; }
    public void setType(String type) { this.type = type; }

    public String getValue() { return value; }
    public void setValue(String value) { this.value = value; }

    @Override
    public String toString() {
        return "Attribute [type=" + type + ", value=" + value + "]";
    }

    @Override
    public int compareTo(Attribute that) {
        return ComparisonChain.start()
            .compare(this.type, that.type)
            .compare(this.value, that.value)
            .result();
    }

}

This is my solution for the problem. You can 'implement' multiple interfaces by overriding one Interface with another.

class MyInterface {
    // Declare your JS doc in the Interface to make it acceable while writing the Class and for later inheritance
    /**
     * Gives the sum of the given Numbers
     * @param {Number} a The first Number
     * @param {Number} b The second Number
     * @return {Number} The sum of the Numbers
     */
    sum(a, b) { this._WARNING('sum(a, b)'); }


    // delcare a warning generator to notice if a method of the interface is not overridden
    // Needs the function name of the Interface method or any String that gives you a hint ;)
    _WARNING(fName='unknown method') {
        console.warn('WARNING! Function "'+fName+'" is not overridden in '+this.constructor.name);
    }
}

class MultipleInterfaces extends MyInterface {
    // this is used for "implement" multiple Interfaces at once
    /**
     * Gives the square of the given Number
     * @param {Number} a The Number
     * @return {Number} The square of the Numbers
     */
    square(a) { this._WARNING('square(a)'); }
}

class MyCorrectUsedClass extends MyInterface {
    // You can easy use the JS doc declared in the interface
    /** @inheritdoc */
    sum(a, b) {
        return a+b;
    }
}
class MyIncorrectUsedClass extends MyInterface {
    // not overriding the method sum(a, b)
}

class MyMultipleInterfacesClass extends MultipleInterfaces {
    // nothing overriden to show, that it still works
}


let working = new MyCorrectUsedClass();

let notWorking = new MyIncorrectUsedClass();

let multipleInterfacesInstance = new MyMultipleInterfacesClass();

// TEST IT

console.log('working.sum(1, 2) =', working.sum(1, 2));
// output: 'working.sum(1, 2) = 3'

console.log('notWorking.sum(1, 2) =', notWorking.sum(1, 2));
// output: 'notWorking.sum(1, 2) = undefined'
// but also sends a warn to the console with 'WARNING! Function "sum(a, b)" is not overridden in MyIncorrectUsedClass'

console.log('multipleInterfacesInstance.sum(1, 2) =', multipleInterfacesInstance.sum(1, 2));
// output: 'multipleInterfacesInstance.sum(1, 2) = undefined'
// console warn: 'WARNING! Function "sum(a, b)" is not overridden in MyMultipleInterfacesClass'

console.log('multipleInterfacesInstance.square(2) =', multipleInterfacesInstance.square(2));
// output: 'multipleInterfacesInstance.square(2) = undefined'
// console warn: 'WARNING! Function "square(a)" is not overridden in MyMultipleInterfacesClass'

EDIT:

I improved the code so you now can simply use implement(baseClass, interface1, interface2, ...) in the extend.

/**
* Implements any number of interfaces to a given class.
* @param cls The class you want to use
* @param interfaces Any amount of interfaces separated by comma
* @return The class cls exteded with all methods of all implemented interfaces
*/
function implement(cls, ...interfaces) {
    let clsPrototype = Object.getPrototypeOf(cls).prototype;
    for (let i = 0; i < interfaces.length; i++) {
        let proto = interfaces[i].prototype;
        for (let methodName of Object.getOwnPropertyNames(proto)) {

Update:

Read the Docs for your version of Django. e.g.

https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/3.0/ref/contrib/admin/#admin-overriding-templates

Original answer from 2011:

I had the same issue about a year and a half ago and I found a nice template loader on djangosnippets.org that makes this easy. It allows you to extend a template in a specific app, giving you the ability to create your own admin/index.html that extends the admin/index.html template from the admin app. Like this:

{% extends "admin:admin/index.html" %}

{% block sidebar %}
    {{block.super}}
    <div>
        <h1>Extra links</h1>
        <a href="/admin/extra/">My extra link</a>
    </div>
{% endblock %}

I've given a full example on how to use this template loader in a blog post on my website.

This is the code:

f = open(filename, 'w')
f.write("hello\talex")

The \t inside the string is the escape sequence for the horizontal tabulation.

Possible solution, you are trying to work with Powerpoint via Excel VBA and you didn't activate Powerpoint Object Library first.

To do this, in the VBA editor top menu select Tools, References, then scroll down to click the library called Microsoft Powerpoint xx.x Object Library. Office 2007 is library 12, each Office version has a different library. FYI, I've experienced some odd errors and file corruption when I activate the 2007 library but someone tries to open and run this macro using Excel 2003. The old version of Excel doesn't recognize the newer library, which seems to cause problems.

It's really a 6 of one, a half-dozen of the other situation.

The only possible argument against your approach is $_SERVER['REQUEST_METHOD'] == 'POST' may not be populated on certain web-servers/configuration, whereas the $_POST array will always exist in PHP4/PHP5 (and if it doesn't exist, you have bigger problems (-:)

Float them both the same way and add the margin of 40px. If you have 2 elements floating opposite ways you will have much less control and the containing element will determine how far apart they are.

#left{
    float: left;
    margin-right: 40px;
}
#right{
   float: left;
}

@dhanushka's approach showed the most promise but I wanted to play around in Python so went ahead and translated it for fun:

import cv2
import numpy as np
from cv2 import boundingRect, countNonZero, cvtColor, drawContours, findContours, getStructuringElement, imread, morphologyEx, pyrDown, rectangle, threshold

large = imread(image_path)
# downsample and use it for processing
rgb = pyrDown(large)
# apply grayscale
small = cvtColor(rgb, cv2.COLOR_BGR2GRAY)
# morphological gradient
morph_kernel = getStructuringElement(cv2.MORPH_ELLIPSE, (3, 3))
grad = morphologyEx(small, cv2.MORPH_GRADIENT, morph_kernel)
# binarize
_, bw = threshold(src=grad, thresh=0, maxval=255, type=cv2.THRESH_BINARY+cv2.THRESH_OTSU)
morph_kernel = getStructuringElement(cv2.MORPH_RECT, (9, 1))
# connect horizontally oriented regions
connected = morphologyEx(bw, cv2.MORPH_CLOSE, morph_kernel)
mask = np.zeros(bw.shape, np.uint8)
# find contours
im2, contours, hierarchy = findContours(connected, cv2.RETR_CCOMP, cv2.CHAIN_APPROX_SIMPLE)
# filter contours
for idx in range(0, len(hierarchy[0])):
    rect = x, y, rect_width, rect_height = boundingRect(contours[idx])
    # fill the contour
    mask = drawContours(mask, contours, idx, (255, 255, 2555), cv2.FILLED)
    # ratio of non-zero pixels in the filled region
    r = float(countNonZero(mask)) / (rect_width * rect_height)
    if r > 0.45 and rect_height > 8 and rect_width > 8:
        rgb = rectangle(rgb, (x, y+rect_height), (x+rect_width, y), (0,255,0),3)

Now to display the image:

from PIL import Image
Image.fromarray(rgb).show()

Not the most Pythonic of scripts but I tried to resemble the original C++ code as closely as possible for readers to follow.

It works almost as well as the original. I'll be happy to read suggestions how it could be improved/fixed to resemble the original results fully.

To turn on "Install via USB" and "USB Debugging(Security changes)" need to sign in to xiaomi account then these 2 can be turned on and work with redmi as developer

Note:When turning on USB Debugging(Security changes) few security alerts will be poped up all need to be accepted to work on developer mode

You can open a new powershell window under a specified user credential like this:

start powershell -credential ""

Why don't you use the Notepad++ multiline editing capabilities?

Hold down Alt while selecting text (using your usual click-and-drag approach) to select text across multiple lines. This is sometimes also referred to as column editing.

You could place the cursor at the beginning of the file, Press (and hold) Alt, Shift and then just keep pressing the down-arrow or PageDown to select the lines that you want to prepend with some text :-) Easy. Multiline editing is a very useful feature of Notepad++. It's also possible in Visual Studio, in the same manner, and also in Eclipse by switching to Block Selection Mode by pressing Alt+Shift+A and then use mouse to select text across lines.

Followup to lxs's answer: I noticed a problem where having both the zoom and --webkit-transform tags at the same time seems to confound Chrome (version 15.0.874.15) by doing a double-zoom sort of effect. I was able to work around the issue by replacing zoom with -ms-zoom (targeted only at IE), leaving Chrome to make use of just the --webkit-transform tag, and that cleared things up.

I have figured it out lol. for the button do .setBounds(0, 0, 220, 30) The .setBounds layout is like this (int x, int y, int width, int height)

use typeof(my_obj) will tells which type of variable it is.

for Array: Array.isArray(inp) or [] isinstanceof Array

if it is object will show 'object'

simple JS function,

function isObj(v) {
    return typeof(v) == "object"
}

Eg:

function isObj(v) {_x000D_
    return typeof(v) == "object"_x000D_
}_x000D_
_x000D_
var samp_obj = {_x000D_
   "a" : 1,_x000D_
   "b" : 2,_x000D_
   "c" : 3_x000D_
}_x000D_
_x000D_
var num = 10;_x000D_
var txt = "Hello World!"_x000D_
var_collection = [samp_obj, num, txt]_x000D_
for (var i in var_collection) {_x000D_
  if(isObj(var_collection[i])) {_x000D_
     console.log("yes it is object")_x000D_
  }_x000D_
  else {_x000D_
     console.log("No it is "+ typeof(var_collection[i]))_x000D_
  }_x000D_
}

Had the same issue with Kepler (after trying to add a Tomcat 7 server).

Whilst adding the server I opted to install the Tomcat binary using the download/install feature inside Eclipse. I added the server without adding any apps. After the install I tried adding an app and got the error.

I immediately deleted the Tomcat 7 server from Eclipse then repeated the same steps to add Tomcat 7 back in (obviously skipping the download/install step as the binary was downloaded first time around).

After adding Tomcat 7 a second time I tried adding / publishing an app and it worked fine. Didn't bother with any further RCA, it started working and that was good enough for me.

A point I think should be added to what other answers mention is that while

List<Dog> isn't-a List<Animal> in Java

it is also true that

A list of dogs is-a list of animals in English (under a reasonable interpretation)

The way the OP's intuition works - which is completely valid of course - is the latter sentence. However, if we apply this intuition we get a language that is not Java-esque in its type system: Suppose our language does allow adding a cat to our list of dogs. What would that mean? It would mean that the list ceases to be a list of dogs, and remains merely a list of animals. And a list of mammals, and a list of quadrapeds.

To put it another way: A List<Dog> in Java does not mean "a list of dogs" in English, it means "a list which can have dogs, and nothing else".

More generally, OP's intuition lends itself towards a language in which operations on objects can change their type, or rather, an object's type(s) is a (dynamic) function of its value.

This is an extension to Langdon's answer with a directive approach to the problem. If you're going to have multiple galleries on the page this may be one way to go about it without much fuss.

Usage:

<gallery images="items"></gallery>
<gallery images="cats"></gallery>

See it working here

I found this article very helpful to understand the difference between them:

RUN - RUN instruction allows you to install your application and packages required for it. It executes any commands on top of the current image and creates a new layer by committing the results. Often you will find multiple RUN instructions in a Dockerfile.

CMD - CMD instruction allows you to set a default command, which will be executed only when you run container without specifying a command. If Docker container runs with a command, the default command will be ignored. If Dockerfile has more than one CMD instruction, all but last
CMD instructions are ignored.

Use the following. It helped me.

document.getElementById('image_1').offsetTop

With params you can call your method like this:

addTwoEach(1, 2, 3, 4, 5);

Without params, you can’t.

Additionally, you can call the method with an array as a parameter in both cases:

addTwoEach(new int[] { 1, 2, 3, 4, 5 });

That is, params allows you to use a shortcut when calling the method.

Unrelated, you can drastically shorten your method:

public static int addTwoEach(params int[] args)
{
    return args.Sum() + 2 * args.Length;
}

Haven't seen any fully-native solutions, so here's one:

return str == null || str.chars().allMatch(Character::isWhitespace);

Basically, use the native Character.isWhitespace() function. From there, you can achieve different levels of optimization, depending on how much it matters (I can assure you that in 99.99999% of use cases, no further optimization is necessary):

return str == null || str.length() == 0 || str.chars().allMatch(Character::isWhitespace);

Or, to be really optimal (but hecka ugly):

int len;
if (str == null || (len = str.length()) == 0) return true;
for (int i = 0; i < len; i++) {
  if (!Character.isWhitespace(str.charAt(i))) return false;
}
return true;

One thing I like to do:

Optional<String> notBlank(String s) {
  return s == null || s.chars().allMatch(Character::isWhitepace))
    ? Optional.empty()
    : Optional.of(s);
}

...

notBlank(myStr).orElse("some default")

I used macports

sudo port install protobuf-cpp

This should do the trick:

Have a read of the grid system section of the Bootstrap docs to familiarise yourself with how Bootstrap's grids work:

It is not clear if the question is about the Microsoft C++ compiler or the Windows API. However, there is no [c++] tag so I assume it is about the Windows API. Some of the answers have suffered from link rot so I am providing yet another link that can rot.

For information about Windows API types like INT, LONG etc. there is a page on MSDN:

Windows Data Types

The information is also available in various Windows header files like WinDef.h. I have listed a few relevant types here:

Type                        | S/U | x86    | x64
----------------------------+-----+--------+-------
BYTE, BOOLEAN               | U   | 8 bit  | 8 bit
----------------------------+-----+--------+-------
SHORT                       | S   | 16 bit | 16 bit
USHORT, WORD                | U   | 16 bit | 16 bit
----------------------------+-----+--------+-------
INT, LONG                   | S   | 32 bit | 32 bit
UINT, ULONG, DWORD          | U   | 32 bit | 32 bit
----------------------------+-----+--------+-------
INT_PTR, LONG_PTR, LPARAM   | S   | 32 bit | 64 bit
UINT_PTR, ULONG_PTR, WPARAM | U   | 32 bit | 64 bit
----------------------------+-----+--------+-------
LONGLONG                    | S   | 64 bit | 64 bit
ULONGLONG, QWORD            | U   | 64 bit | 64 bit

The column "S/U" denotes signed/unsigned.

There are multiple classes that are grouped together as "numeric" classes, the 2 most common of which are double (for double precision floating point numbers) and integer. R will automatically convert between the numeric classes when needed, so for the most part it does not matter to the casual user whether the number 3 is currently stored as an integer or as a double. Most math is done using double precision, so that is often the default storage.

Sometimes you may want to specifically store a vector as integers if you know that they will never be converted to doubles (used as ID values or indexing) since integers require less storage space. But if they are going to be used in any math that will convert them to double, then it will probably be quickest to just store them as doubles to begin with.

You can use SQLAlchemy's or_ function to search in more than one column (the underscore is necessary to distinguish it from Python's own or).

Here's an example:

from sqlalchemy import or_
query = meta.Session.query(User).filter(or_(User.firstname.like(searchVar),
                                            User.lastname.like(searchVar)))

Column names can contain characters and reserved words that will confuse the query execution engine, so placing brackets around them at all times prevents this from happening. Easier than checking for an issue and then dealing with it, I guess.

2 more helpful methods: System.Environment.GetEnvironmentVariable("ComputerName" )

System.Environment.GetEnvironmentVariable("ClientName" ) to get the name of the user's PC if they're connected via Citrix XenApp or Terminal Services (aka RDS, RDP, Remote Desktop)

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

The above answers are partially correct, but with "tel://" there is only one issue. After the call has ended, it will return to the homescreen, not to our app. So better to use "telprompt://", it will return to the app.

var url:NSURL = NSURL(string: "telprompt://1234567891")!
UIApplication.sharedApplication().openURL(url)

You can take advantage of the HTML prompt to unload mechanism, by specifying no unload handler:

window.onbeforeunload = null;
window.location.replace(URL);

See the notes section of the WindowEventHandlers.onbeforeunload for more information.

I did it one time with a workaround, hope it helps.

string fullName = typeof(MyObj).FullName;

switch (fullName)
{
    case "fullName1":
    case "fullName2":
    case "fullName3":
}

<item name="android:textSize">15dp</item>

I don't have reputation to comment yet, but I want to add to alko answer for further reference.

From the docs:

skiprows: A collection of numbers for rows in the file to skip. Can also be an integer to skip the first n rows

If it is possible to change the sequence of the lines you could do:

1. sort line with Edit -> Line Operations -> Sort Lines Lexicographically ascending
2. do a Find / Replace:
   • Find What: ^(.*\r?\n)\1+
   • Replace with: (Nothing, leave empty)
   • Check Regular Expression in the lower left
   • Click Replace All

How it works: The sorting puts the duplicates behind each other. The find matches a line ^(.*\r?\n) and captures the line in \1 then it continues and tries to find \1 one or more times (+) behind the first match. Such a block of duplicates (if it exists) is replaced with nothing.

The \r?\n should deal nicely with Windows and Unix lineendings.

Named pipes is a windows system for inter-process communication. In the case of SQL server, if the server is on the same machine as the client, then it is possible to use named pipes to tranfer the data, as opposed to TCP/IP.

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

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

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

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

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

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

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

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

From number to currency string is easy through Number.prototype.toLocaleString. However the reverse seems to be a common problem. The thousands separator and decimal point may not be obtained in the JS standard.

In this particular question the thousands separator is a white space " " but in many cases it can be a period "." and decimal point can be a comma ",". Such as in 1 000 000,00 or 1.000.000,00. Then this is how i convert it into a proper floating point number.

var price = "1 000.000,99",
    value = +price.replace(/(\.|\s)|(\,)/g,(m,p1,p2) => p1 ? "" : ".");
console.log(value);

So the replacer callback takes "1.000.000,00" and converts it into "1000000.00". After that + in the front of the resulting string coerces it into a number.

This function is actually quite handy. For instance if you replace the p1 = "" part with p1 = "," in the callback function, an input of 1.000.000,00 would result 1,000,000.00

If you are using the background image for the rounded corners then I would rather increase the padding style of the main div to give enough room for the rounded corners of the background image to be visible.

Try increasing the padding of the main div style:

#mainWrapperDivWithBGImage 
{   
    background: url("myImageWithRoundedCorners.jpg") no-repeat scroll 0 0 transparent;   
    height: 248px;   
    margin: 0;   
    overflow: hidden;   
    padding: 10px 10px;   
    width: 996px; 
}

P.S: I assume the rounded corners have a radius of 10px.

You can consider using memory-mapped files, via FileChannels .

Generally a lot faster for large files. There are performance trade-offs that could make it slower, so YMMV.

Related answer: Java NIO FileChannel versus FileOutputstream performance / usefulness

If you want to add the current date into the database, I would avoid calculating the date in Java to begin with. Determining "now" on the Java (client) side leads to possible inconsistencies in the database if the client side is mis-configured, has the wrong time, wrong timezone, etc. Instead, the date can be set on the server side in a manner such as the following:

requestSQL = "INSERT INTO CREDIT_REQ_TITLE_ORDER ("   +
                "REQUEST_ID, ORDER_DT, FOLLOWUP_DT) " +
                "VALUES(?, SYSDATE, SYSDATE + 30)";

...

prs.setInt(1, new Integer(requestID));

This way, only one bind parameter is required and the dates are calculated on the server side will be consistent. Even better would be to add an insert trigger to CREDIT_REQ_TITLE_ORDER and have the trigger insert the dates. That can help enforce consistency between different client apps (for example, someone trying to do a fix via sqlplus.

The simple way to get a date x days in the future is to increment the date:

function addDays(dateObj, numDays) {
  return dateObj.setDate(dateObj.getDate() + numDays);
}

Note that this modifies the supplied date object, e.g.

function addDays(dateObj, numDays) {
   dateObj.setDate(dateObj.getDate() + numDays);
   return dateObj;
}

var now = new Date();
var tomorrow = addDays(new Date(), 1);
var nextWeek = addDays(new Date(), 7);

alert(
    'Today: ' + now +
    '\nTomorrow: ' + tomorrow +
    '\nNext week: ' + nextWeek
);

You can do it. That is what big guys do as well.

As you see, the list of IPs rotated around, but the relative order between two IPs stayed the same.

Update: I see several comments bragging about how DNS round-robin is not convenient for fail-over, so here is the summary: DNS is not for fail-over. So it is obviously not good for fail-over. It was never designed to be a solution for fail-over.

You can try this:

    header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
    header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
    header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
    header("Cache-Control: post-check=0, pre-check=0", false);
    header("Pragma: no-cache");
    header("Connection: close");

Hopefully it will help prevent Cache, if any!

You should use

<input type="submit" value="submit" />

inside your form.

and add action into your form tag for example:

<form action="booking.php" method="post">

It's post your form into action which you choose.

From php you can get this value by

$_POST['booking-check'];

I know this isn't a direct answer to your question, but you could also consider using clip-path, as in this question: https://stackoverflow.com/a/18208889/23341.

There is a

idea64.exe

starter in

IntelliJ IDEA 13.1.5\bin

so you can address more space.

Yes you can; it works on Android too:

tel: phone_number
Calls the entered phone number. Valid telephone numbers as defined in the IETF RFC 3966 are accepted. Valid examples include the following:

* tel:2125551212
* tel: (212) 555 1212

The Android browser uses the Phone app to handle the “tel” scheme, as defined by RFC 3966.
Clicking a link like:

<a href="tel:2125551212">2125551212</a>

on Android will bring up the Phone app and pre-enter the digits for 2125551212 without autodialing.

Have a look to RFC3966

You may change the pg_hba.conf and then reload the postgresql. something in the pg_hba.conf may be like below:

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

then you change your user to postgresql, you may login successfully.

su postgresql

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) {
...
}

Adding for completeness of the answers: preloading with HTML

<link rel="preload" href="bg-image-wide.png" as="image">

Other preloading features exist, but none are quite as fit for purpose as <link rel="preload">:

• <link rel="prefetch"> has been supported in browsers for a long time, but it is intended for prefetching resources that will be used in the next navigation/page load (e.g. when you go to the next page). This is fine, but isn't useful for the current page! In addition, browsers will give prefetch resources a lower priority than preload ones — the current page is more important than the next. See Link prefetching FAQ for more details.
• <link rel="prerender"> renders a specified webpage in the background, speeding up its load if the user navigates to it. Because of the potential to waste users bandwidth, Chrome treats prerender as a NoState prefetch instead.
• <link rel="subresource"> was supported in Chrome a while ago, and was intended to tackle the same issue as preload, but it had a problem: there was no way to work out a priority for the items (as didn't exist back then), so they all got fetched with fairly low priority.

There are a number of script-based resource loaders out there, but they don't have any power over the browser's fetch prioritization queue, and are subject to much the same performance problems.

The keytool command will not allow you to export the private key from a key store. You have to write some Java code to do this. Open the key store, get the key you need, and save it to a file in PKCS #8 format. Save the associated certificate too.

KeyStore ks = KeyStore.getInstance("jks");
/* Load the key store. */
...
char[] password = ...;
/* Save the private key. */
FileOutputStream kos = new FileOutputStream("tmpkey.der");
Key pvt = ks.getKey("your_alias", password);
kos.write(pvt.getEncoded());
kos.flush();
kos.close();
/* Save the certificate. */
FileOutputStream cos = new FileOutputStream("tmpcert.der");
Certificate pub = ks.getCertificate("your_alias");
cos.write(pub.getEncoded());
cos.flush();
cos.close();

Use OpenSSL utilities to convert these files (which are in binary format) to PEM format.

openssl pkcs8 -inform der -nocrypt < tmpkey.der > tmpkey.pem
openssl x509 -inform der < tmpcert.der > tmpcert.pem

this could help..

curl 'http://example.com' > /dev/null

I think this is more straightforward:

var date365 = 0;

var currentDate = new Date();
var currentYear = currentDate.getFullYear();
var currentMonth = currentDate.getMonth(); 
var currentDay = currentDate.getDate(); 

var monthLength = [31,28,31,30,31,30,31,31,30,31,30,31];

var leapYear = new Date(currentYear, 1, 29); 
if (leapYear.getDate() == 29) { // If it's a leap year, changes 28 to 29
    monthLength[1] = 29;
}

for ( i=0; i < currentMonth; i++ ) { 
    date365 = date365 + monthLength[i];
}
date365 = date365 + currentDay; // Done!

This is by far the best post for exporting to excel from SQL:

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926

To quote from user madhivanan,

Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel

Create an Excel file named testing having the headers same as that of table columns and use these queries

1 Export data to existing EXCEL file from SQL Server table

insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;', 
    'SELECT * FROM [SheetName$]') select * from SQLServerTable

2 Export data from Excel to new SQL Server table

select * 
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [Sheet1$]')

3 Export data from Excel to existing SQL Server table (edited)

Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [SheetName$]')

4 If you dont want to create an EXCEL file in advance and want to export data to it, use

EXEC sp_makewebtask 
    @outputfile = 'd:\testing.xls', 
    @query = 'Select * from Database_name..SQLServerTable', 
    @colheaders =1, 
    @FixedFont=0,@lastupdated=0,@resultstitle='Testing details'

(Now you can find the file with data in tabular format)

5 To export data to new EXCEL file with heading(column names), create the following procedure

create procedure proc_generate_excel_with_columns
(
    @db_name    varchar(100),
    @table_name varchar(100),   
    @file_name  varchar(100)
)
as

--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select 
    @columns=coalesce(@columns+',','')+column_name+' as '+column_name 
from 
    information_schema.columns
where 
    table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')

--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'

--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)

--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)

--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)

--Delete dummy file 
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)

After creating the procedure, execute it by supplying database name, table name and file path:

EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'

Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.

Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.

To update single cells

A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?

This is the principle of how you do manage that

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = -99

You can also add formulas to Excel using this:

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = '=a7+c7'

Exporting with column names using T-SQL

Member Mladen Prajdic also has a blog entry on how to do this here

References: www.sqlteam.com (btw this is an excellent blog / forum for anyone looking to get more out of SQL Server). For error referencing I used this

Errors that may occur

If you get the following error:

OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries

Then run this:

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO

use FORMACTION

<input type="submit" value="Delete" formaction="@Url.Action("Delete", new { id = Model.Id })" />

If name is a PK, then just insert and catch the error. The reason to do this rather than any check is that it will work even with multiple clients inserting at the same time. If you check and then insert, you have to hold a lock during that time, or expect the error anyway.

The code for this would be something like

BEGIN
  INSERT INTO table( name, age )
    VALUES( 'johnny', null );
EXCEPTION
  WHEN dup_val_on_index
  THEN
    NULL; -- Intentionally ignore duplicates
END;

cpp is the preprocessor.

Run cpp filename.c to output the preprocessed code, or better, redirect it to a file with cpp filename.c > filename.preprocessed.

If you only need the default style, make sure you have the following width/height, otherwise the numStars could get messed up:

android:layout_width="wrap_content"
android:layout_height="wrap_content"

In Bootstrap 4 you can use the form-check-inline class.

<div class="form-check form-check-inline">
  <input class="form-check-input" type="radio" name="queryFieldName" id="option1" value="1">
  <label class="form-check-label" for="option1">First</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="radio" name="queryFieldName" id="option2" value="2">
  <label class="form-check-label" for="option2">Second</label>
</div>

Copy the folder, firefox.exe is in and place in the c:\ only. The script is having a hard time climbing your file tree. I found that when I placed the *.exe file in the c:\ it eliminated the error message " file not found."

  var number = Math.floor(Math.random() * 9000000000) + 1000000000;_x000D_
    console.log(number);

This can be simplest way and reliable one.

Try this set of code to download a CSV file from the server.

byte[] Content= File.ReadAllBytes(FilePath); //missing ;
Response.ContentType = "text/csv";
Response.AddHeader("content-disposition", "attachment; filename=" + fileName + ".csv");
Response.BufferOutput = true;
Response.OutputStream.Write(Content, 0, Content.Length);
Response.End();

The W3Schools example isn't saying when you should use compound primary keys, and is only giving example syntax using the same example table as for other keys.

Their choice of example is perhaps misleading you by combining a meaningless key (P_Id) and a natural key (LastName). This odd choice of primary key says that the following rows are valid according to the schema and are necessary to uniquely identify a student. Intuitively this doesn't make sense.

1234     Jobs
1234     Gates

Further Reading: The great primary-key debate or just Google meaningless primary keys or even peruse this SO question

FWIW - My 2 cents is to avoid multi-column primary keys and use a single generated id field (surrogate key) as the primary key and add additional (unique) constraints where necessary.

I'm having the same problem to solve, because I need to install JDK8 to run Android SDK Manager (because it seems that don't work well with JDK9). However, I tell you how I solve all problems on a Mac (Sierra).

First, you need brew with cask and jenv.

1. You can find an useful guide here,Homebrew Cask Installation Guide. Remember to tap 'caskroom/versions' running in the terminal: brew tap caskroom/versions
2. After that, install jenv with: brew install jenv
3. Install whatever version you want with cask brew cask install java8 (or java7 or java if you want to install the latest version, jdk9)
4. The last step is to configure which version to run (and let jenv to manage your JAVA_HOME) jenv versions to list all versions installed on your machine and then activate the one you want with jenv global [JDK_NAME_OF_LIST]

You could find other useful informations here on this Github Gist brew-java-and-jenv.md, on this blog Install multiple JDK on a Mac and on Jenv Website

AndroidX is the open-source project that the Android team uses to develop, test, package, version and release libraries within Jetpack.

After hours of struggling, I solved it by including the following within app/build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Put these flags in your gradle.properties

android.enableJetifier=true
android.useAndroidX=true

Changes in gradle:

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha04'

When migrating on Android studio, the app/gradle file is automatically updated with the correction library impleemntations from the standard library

Refer to: https://developer.android.com/jetpack/androidx/migrate

You won't need a plugin to see commit history with Visual Studio Code 1.42 or more.

Timeline view

In this milestone, we've made progress on the new Timeline view, and have an early preview to share.
This is a unified view for visualizing time-series events (e.g. commits, saves, test runs, etc.) for a resource (file, folder, etc.).

To enable the Timeline view, you must be using the Insiders Edition (VSCode 1.44 March 2020) and then add the following setting:

"timeline.showView": true

Comment.find(:all, :conditions =>["date(created_at) BETWEEN ? AND ? ", '2011-11-01','2011-11-15'])

compatible utf-8 encoding

def _pad(self, s):
    s = s.encode()
    res = s + (self.bs - len(s) % self.bs) * chr(self.bs - len(s) % self.bs).encode()
    return res

This is an example where I use the table variable to list multiple values in an IN clause. The obvious reason is to be able to change the list of values only one place in a long procedure.

To make it even more dynamic and alowing user input, I suggest declaring a varchar variable for the input, and then using a WHILE to loop trough the data in the variable and insert it into the table variable.

Replace @your_list, Your_table and the values with real stuff.

DECLARE @your_list TABLE (list varchar(25)) 
INSERT into @your_list
VALUES ('value1'),('value2376')

SELECT *  
FROM your_table 
WHERE your_column in ( select list from @your_list )

The select statement abowe will do the same as:

SELECT *  
FROM your_table 
WHERE your_column in ('value','value2376' )

If your testing requires pulling quasi-real credit reports from the bureaus, the inactive SSNs of other answers won't work and you'll need designated test numbers.

I found this site Which appears to contain test social security numbers with associated test names and credit card numbers.

Transunion has a test environment you can link and send data to, including associated dummy credit reports. Sending a SSN to them with certain numbers in certain positions will automatically route the inquiry to their test environment Other credit bureaus will have similar systems in place.

Json.NET - Documentation

http://james.newtonking.com/json/help/index.html?topic=html/SelectToken.htm

Interpretation for the author

var o = JObject.Parse(response);
var a = o.SelectToken("data").Select(jt => jt.ToObject<TheUser>()).ToList();

You should first make a String that holds all of the letters/numbers that you want.
Then, make a Random. e. g. Random rnd = new Random;
Finally, make something that actually gets a random character from your String containing your alphabet.
For example,

import java.util.Random;

public class randomCharacter {
    public static void main(String[] args) {
        String alphabet = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ?/.,";
        Random rnd = new Random();
        char char = alphabet.charAt(rnd.nextInt(alphabet.length()));
        // do whatever you want with the character
    }
}

See this.
It's where I got this info from.

Regarding 3rd definition:

var foo = function foo() { return 5; }

Heres an example which shows how to use possibility of recursive call:

a = function b(i) { 
  if (i>10) {
    return i;
  }
  else {
    return b(++i);
  }
}

console.log(a(5));  // outputs 11
console.log(a(10)); // outputs 11
console.log(a(11)); // outputs 11
console.log(a(15)); // outputs 15

Edit: more interesting example with closures:

a = function(c) {
 return function b(i){
  if (i>c) {
   return i;
  }
  return b(++i);
 }
}
d = a(5);
console.log(d(3)); // outputs 6
console.log(d(8)); // outputs 8

it could be done when the RowDataBound event fires

  protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      // Hide the edit button when some condition is true
      // for example, the row contains a certain property
      if (someCondition) 
      {
          Button btnEdit = (Button)e.Row.FindControl("btnEdit");

          btnEdit.Visible = false;
      }
    }   
  }

                }
        }

        private static List<Customer> GetCustomers()
        {
            List<Customer> results = new List<Customer>();

            results.Add(new Customer("Steve", 30));
            results.Add(new Customer("Brian", 40));
            results.Add(new Customer("Dave", 50));
            results.Add(new Customer("Bill", 25));
            results.Add(new Customer("Rich", 22));
            results.Add(new Customer("Bert", 30));

            return results;
        }
    }

    public class Customer
    {
        public string Name {get;set;}
        public int Age { get; set; }

        public Customer(string name, int age)
        {
            Name = name;
            Age = age;
        }
    }

In the demo, the Edit Button is not Visible (the HTML markup is not sent to the client) in those rows where the Customer's age is 30.

Another solution is to run logic via sequential executor nsynjs. It reads file line-by-line using node readline module, and it doesn't use promises or recursion, therefore not going to fail on large files. Here is how the code will looks like:

var nsynjs = require('nsynjs');
var textFile = require('./wrappers/nodeReadline').textFile; // this file is part of nsynjs

function process(textFile) {

    var fh = new textFile();
    fh.open('path/to/file');
    var s;
    while (typeof(s = fh.readLine(nsynjsCtx).data) != 'undefined')
        console.log(s);
    fh.close();
}

var ctx = nsynjs.run(process,{},textFile,function () {
    console.log('done');
});

Code above is based on this exampe: https://github.com/amaksr/nsynjs/blob/master/examples/node-readline/index.js

<script type="text/javascript">
    $(document).ready(function () {
        $('#btnadd').on('click', function () {
            var n1 = parseInt($('#txtn1').val());
            var n2 = parseInt($('#txtn2').val());
            var r = n1 + n2;
            alert("sum of 2 No= " + r);
            return false;
        });
        $('#btnclear').on('click', function () {
            $('#txtn1').val('');
            $('#txtn2').val('');
            $('#txtn1').focus();
            return false;
        });
    });
</script>

if you are using php then....

try{
$con = new PDO ("mysql:host=localhost;dbname=dbasename","root","");
}
catch(PDOException $e){
echo "error".$e-getMessage();   
}

$select = $con->prepare("SELECT * FROM table");
$select->setFetchMode(PDO::FETCH_ASSOC);
$select->execute();

while($data=$select->fetch()){ 

$id = $data['id'];
$column = $data['column'];
$column = preg_replace("/[^a-zA-Z0-9]+/", " ", $column); //remove all special characters

$update = $con->prepare("UPDATE table SET column=:column WHERE id='$id'");
$update->bindParam(':column', $column );
$update->execute();

// echo $column."<br>";
} 

in my case, i solved this issue by adding the full URL and not only the domain as facebook ask. i hope that they will rename it for more clarification. so the Valid OAuth Redirect URIs should be like so:

After: https://www.mobile-battles.com/register

Can't we do waitfor /T 180?

waitfor /T 180 pause will result in "ERROR: Timed out waiting for 'pause'."

waitfor /T 180 pause >nul will sweep that "error" under the rug

The waitfor command should be there in Windows OS after Win95

In the past I've downloaded a executable named sleep that will work on the command line after you put it in your path.

For example: sleep shutdown -r -f /m \\yourmachine although shutdown now has -t option built in

This scope https://www.googleapis.com/auth/userinfo.profile has been deprecated now. Please look at https://developers.google.com/+/api/auth-migration#timetable.

New scope you will be using to get profile info is: profile or https://www.googleapis.com/auth/plus.login

and the endpoint is - https://www.googleapis.com/plus/v1/people/{userId} - userId can be just 'me' for currently logged in user.

As pointed out by @bertolami, it's not possible to us a variable type and get its future value (the content of typeOfList variable).

Nevertheless, you can pass the class as parameter on it like this:

public final class voodoo {
    public static void chill(List<T> aListWithTypeSpiderMan, Class<T> clazz) {
        // Here I'd like to get the Class-Object 'SpiderMan'
        Class typeOfTheList = clazz;
    }

    public static void main(String... args) {
        chill(new List<SpiderMan>(), Spiderman.class );
    }
}

That's more or less what Google does when you have to pass a class variable to the constructor of ActivityInstrumentationTestCase2.

The paint() method supports painting via a Graphics object.

The repaint() method is used to cause paint() to be invoked by the AWT painting thread.

I know this is an old post, but there is a FAR simpler answer (though maybe it only works in newer versions of windows). Just use the /t parameter for the DATE and TIME dos commands to only show the date or time and not prompt you to set it, like this:

@echo off
echo Starting test batch file > testlog.txt
date /t >> testlog.txt
time /t >> testlog.txt

bw.newLine(); cannot ensure compatibility with all systems.

If you are sure it is going to be opened in windows, you can format it to windows newline.

If you are already using native unix commands, try unix2dos and convert teh already generated file to windows format and then send the mail.

If you are not using unix commands and prefer to do it in java, use ``bw.write("\r\n")` and if it does not complicate your program, have a method that finds out the operating system and writes the appropriate newline.

call below method on div or body tag onclick="show(event);" function show(event) {

        var x = event.clientX;
        var y = event.clientY;

        var ele = document.getElementById("tt");
        var width = ele.offsetWidth;
        var height = ele.offsetHeight;
        var half=(width/2);
       if(x>half)
        {
          //  alert('right click');
            gallery.next();
        }
        else
       {
           //   alert('left click');
            gallery.prev();
        }


    }

I ran across this error when i ran cordova build android

I solved this issue by firing ./sdkmanager --licenses and accepting all the licenses.

1. You have a sdkmanager.bat under the android sdk folder in the path: android/sdk/tools/bin
2. To trigger that open a command prompt in android/sdk/tools/bin
3. type ./sdkmanager --licenses and enter
4. Press y to review all licenses and then press y to accept all licenses

You can Autowire the ApplicationContext, either as a field

@Autowired
private ApplicationContext context;

or a method

@Autowired
public void context(ApplicationContext context) { this.context = context; }

Finally use

context.getBean(SomeClass.class)

One quick solution that came to mind :-

<input type="checkbox" id="markitem" name="markitem" value="1" onchange="GetMarkedItems(1)">
<label for="markitem" style="position:absolute; top:1px; left:165px;">&nbsp</label>
<!-- Fire the below javascript everytime the page reloads -->
<script type=text/javascript>
  document.getElementById("markitem").checked = false;
</script>
<!-- Tested on Latest FF, Chrome, Opera and IE. -->

When dealing with dates in SQL Server, the ISO-8601 format is probably the best way to go, since it just works regardless of your language and culture settings.

In order to INSERT data into a SQL Server table, you don't need any conversion codes or anything at all - just specify your dates as literal strings

INSERT INTO MyTable(DateColumn) VALUES('20090430 12:34:56.790')

and you're done.

If you need to convert a date column to ISO-8601 format on SELECT, you can use conversion code 126 or 127 (with timezone information) to achieve the ISO format.

SELECT CONVERT(VARCHAR(33), DateColumn, 126) FROM MyTable

should give you:

2009-04-30T12:34:56.790

you have 2 options:

If you know the size of vector will be (in your case/example it's seems you know it):

vector<int> V(size)
for(int i =0;i<size;i++){
    cin>>V[i];
 }

if you don't and you can't get it in you'r program flow then:

int helper;
while(cin>>helper){
    V.push_back(helper);
}

I use this code to costum my bottom navigation item

BottomNavigationView navigation = this.findViewById(R.id.my_bottom_navigation);
Menu menu = navigation.getMenu();
menu.findItem(R.id.nav_wall_see).setTitle("Hello");

Just wanted to point out that the accepted answer has a couple of limitations (which I discovered when I tried to use it)

1. As written, it actually keeps recalculating the font size based on a ratio of the previous font size... thus after just a couple of calls it has rendered the font size as much too large. (eg Start with 12 point as your DESIGNED Font, expand the label by just 1 pixel, and the published code will calculate the Font size as 12 * (say) 1.2 (ratio of field space to text) = 14.4 or 14 point font. 1 more Pixel and call and you are at 16 point !).

It is thus not suitable (without adaptation) for use in a repeated-call setting (eg a ComponentResizedListener, or a custom/modified LayoutManager).

The listed code effectively assumes a starting size of 10 pt but refers to the current font size and is thus suitable for calling once (to set the size of the font when the label is created). It would work better in a multi-call environment if it did int newFontSize = (int) (widthRatio * 10); rather than int newFontSize = (int)(labelFont.getSize() * widthRatio);

2. Because it uses new Font(labelFont.getName(), Font.PLAIN, fontSizeToUse)) to generate the new font, there is no support for Bolding, Italic or Color etc from the original font in the updated font. It would be more flexible if it made use of labelFont.deriveFont instead.

3. The solution does not provide support for HTML label Text. (I know that was probably not ever an intended outcome of the answer code offered, but as I had an HTML-text JLabel on my JPanel I formally discovered the limitation. The FontMetrics.stringWidth() calculates the text length as inclusive of the width of the html tags - ie as simply more text)

I recommend looking at the answer to this SO question where trashgod's answer points to a number of different answers (including this one) to an almost identical question. On that page I will provide an additional answer that speeds up one of the other answers by a factor of 30-100.

Without repeating the same thing in previous answers,
I'm writing this answer for the people who are looking to starting a new project and don't know which is the best framework to startup your project. If you are a beginner to this framework the best thing I prefer is Use spring boot(with STS /Spring Tool Suite). Because it helps a lot. Its do all configurations on its own. Additionally, use Hibernate with spring-boot as a database framework. With this combination, your application will be the best. I can guarantee that with my experiences.

Even this is one of the best frameworks for JEE(in present) this is gonna die in the near future. There are lightweight alternatives coming up. So keep updated with your experience don't stick to one particular framework. The best thing is being fluent in concepts, not in the frameworks.

To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

let maxDate = new Date(8640000000000000);_x000D_
let minDate = new Date(-8640000000000000);_x000D_
_x000D_
console.log(new Date(maxDate.getTime()).toString());_x000D_
console.log(new Date(maxDate.getTime() - 1).toString());_x000D_
console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

No, there are definitely times where you would not want to use [unowned self]. Sometimes you want the closure to capture self in order to make sure that it is still around by the time the closure is called.

Example: Making an asynchronous network request

If you are making an asynchronous network request you do want the closure to retain self for when the request finishes. That object may have otherwise been deallocated but you still want to be able to handle the request finishing.

When to use unowned self or weak self

The only time where you really want to use [unowned self] or [weak self] is when you would create a strong reference cycle. A strong reference cycle is when there is a loop of ownership where objects end up owning each other (maybe through a third party) and therefore they will never be deallocated because they are both ensuring that each other stick around.

In the specific case of a closure, you just need to realize that any variable that is referenced inside of it, gets "owned" by the closure. As long as the closure is around, those objects are guaranteed to be around. The only way to stop that ownership, is to do the [unowned self] or [weak self]. So if a class owns a closure, and that closure captures a strong reference to that class, then you have a strong reference cycle between the closure and the class. This also includes if the class owns something that owns the closure.

Specifically in the example from the video

In the example on the slide, TempNotifier owns the closure through the onChange member variable. If they did not declare self as unowned, the closure would also own self creating a strong reference cycle.

Difference between unowned and weak

The difference between unowned and weak is that weak is declared as an Optional while unowned is not. By declaring it weak you get to handle the case that it might be nil inside the closure at some point. If you try to access an unowned variable that happens to be nil, it will crash the whole program. So only use unowned when you are positive that variable will always be around while the closure is around

Regarding your question,

It is the same both 'on' or 'where' on an inner join as long as your server can get it:

select * from a inner join b on a.c = b.c

and

select * from a inner join b where a.c = b.c

The 'where' option not all interpreters know so maybe should be avoided. And of course the 'on' clause is clearer.

It looks like you are running into a bug in the way NetBeans 6.8 creates the jar for a Java Library Project.

The issue implies that there is a work-around.

I have not been able to verify that with NB 6.8 and/or NetBeans 6.9-dev...

You may want to register with the NetBeans.org website/issue tracker and update the issue and add your 'vote'.

here is how you can run it in multiple browsers for windows

{
 "version": "0.1.0",
 "command": "cmd",
 "args": ["/C"],
 "isShellCommand": true,
 "showOutput": "always",
 "suppressTaskName": true,
 "tasks": [
     {   
         "taskName": "Chrome",
         "args": ["start chrome -incognito \"${file}\""]
     },
     {   
         "taskName": "Firefox",
         "args": ["start firefox -private-window \"${file}\""]
     },
     {   
         "taskName": "Edge",
         "args": ["${file}"]
     }   
    ]
}

notice that I didn't type anything in args for edge because Edge is my default browser just gave it the name of the file.

EDIT: also you don't need -incognito nor -private-window...it's just me I like to view it in a private window

If I'm reading your question correctly, objects in general are agnostic about where they are contained. They don't know who their parents are. To find that information, you have to parse the parent data structure. The DOM has ways of doing this for us when you're talking about element objects in a document, but it looks like you're talking about vanilla objects.

Based on gbinflames' answer, this is what worked for me:

Generate a simple mailchimp list sign up form , copy the action URL and method (post) to your custom form. Also rename your form field names to all capital ( name='EMAIL' as in original mailchimp code, EMAIL,FNAME,LNAME,... ), then use this:

      $form=$('#your-subscribe-form'); // use any lookup method at your convenience

      $.ajax({
      type: $form.attr('method'),
      url: $form.attr('action').replace('/post?', '/post-json?').concat('&c=?'),
      data: $form.serialize(),
      timeout: 5000, // Set timeout value, 5 seconds
      cache       : false,
      dataType    : 'jsonp',
      contentType: "application/json; charset=utf-8",
      error       : function(err) { // put user friendly connection error message  },
      success     : function(data) {
          if (data.result != "success") {
              // mailchimp returned error, check data.msg
          } else {
              // It worked, carry on...
          }
      }

In addition to the other answers here showing you how to git checkout <the-hash-you-want> it's worth knowing you can switch back to where you were using:

git checkout @{-1}

This is often more convenient than:

git checkout what-was-that-original-branch-called-again-question-mark

As you might anticipate, git checkout @{-2} will take you back to the branch you were at two git checkouts ago, and similarly for other numbers. If you can remember where you were for bigger numbers, you should get some kind of medal for that.

Sadly for productivity, git checkout @{1} does not take you to the branch you will be on in future, which is a shame.

Check your servers error log, typically /var/log/apache2/error.log.

Here is a concrete example with the delegation pattern.

Setup your Protocol:

@objc protocol MyProtocol:class
{
    func requiredMethod()
    optional func optionalMethod()
}

class MyClass: NSObject
{
    weak var delegate:MyProtocol?

    func callDelegate()
    {
        delegate?.requiredMethod()
        delegate?.optionalMethod?()
    }
}

Set the delegate to a class and implement the Protocol. See that the optional method does not need to be implemented.

class AnotherClass: NSObject, MyProtocol
{
    init()
    {
        super.init()

        let myInstance = MyClass()
        myInstance.delegate = self
    }

    func requiredMethod()
    {
    }
}

One important thing is that the optional method is optional and needs a "?" when calling. Mention the second question mark.

delegate?.optionalMethod?()

You can use the append() function to insert items into vectors or lists (dataframes are lists). Simply:

df <- data.frame(a=c(1,2), b=c(3,4), c=c(5,6))

df <- as.data.frame(append(df, list(d=df$b+df$c), after=2))

Or, if you want to specify the position by name use which:

df <- as.data.frame(append(df, list(d=df$b+df$c), after=which(names(df)=="b")))

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

There is a way to turn the validation back to 2.0 for one page. Just add the below code to your web.config:

<configuration>
    <location path="XX/YY">
        <system.web>
            <httpRuntime requestValidationMode="2.0" />
        </system.web>
    </location>

    ...
    the rest of your configuration
    ...

</configuration>

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

I'm on OSX 10.10.2, and succeeded in using JPype.

Ran into installation problems with Jnius (others have too), Javabridge installed but gave mysterious errors when I tried to use it, PyJ4 has this inconvenience of having to start a Gateway server in Java first, JCC wouldn't install. Finally, JPype ended up working. There's a maintained fork of JPype on Github. It has the major advantages that (a) it installs properly and (b) it can very efficiently convert java arrays to numpy array (np_arr = java_arr[:])

The installation process was:

git clone https://github.com/originell/jpype.git
cd jpype
python setup.py install

And you should be able to import jpype

The following demo worked:

import jpype as jp
jp.startJVM(jp.getDefaultJVMPath(), "-ea")
jp.java.lang.System.out.println("hello world")
jp.shutdownJVM() 

When I tried calling my own java code, I had to first compile (javac ./blah/HelloWorldJPype.java), and I had to change the JVM path from the default (otherwise you'll get inexplicable "class not found" errors). For me, this meant changing the startJVM command to:

jp.startJVM('/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/MacOS/libjli.dylib', "-ea")
c = jp.JClass('blah.HelloWorldJPype')  
# Where my java class file is in ./blah/HelloWorldJPype.class
...

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

Replace all non-digit with blank: the remaining string contains only digits.

Integer.parseInt(s.replaceAll("[\\D]", ""))

This will also remove non-digits inbetween digits, so "x1x1x" becomes 11.

If you need to confirm that the string consists of a sequence of digits (at least one) possibly followed a letter, then use this:

s.matches("[\\d]+[A-Za-z]?")

What about this?

SELECT c.id, c.title, (SELECT id from products AS p 
                            WHERE c.id = p.category_id 
                            ORDER BY ... 
                            LIMIT 1)
   FROM categories AS c;
