Angular-cli includes the assets folder in the build options by default. I got this issue when the name of my images had spaces or dashes. For example :

• 'my-image-name.png' should be 'myImageName.png'
• 'my image name.png' should be 'myImageName.png'

If you put the image in the assets/img folder, then this line of code should work in your templates :

<img alt="My image name" src="./assets/img/myImageName.png">

If the issue persist just check if your Angular-cli config file and be sure that your assets folder is added in the build options.

Map is a part of the enumerable module. Very similar to "collect" For Example:

  Class Car

    attr_accessor :name, :model, :year

    Def initialize (make, model, year)
      @make, @model, @year = make, model, year
    end

  end

  list = []
  list << Car.new("Honda", "Accord", 2016)
  list << Car.new("Toyota", "Camry", 2015)
  list << Car.new("Nissan", "Altima", 2014)

  p list.map {|p| p.model}

Map provides values iterating through an array that are returned by the block parameters.

You're mixing up two separate concepts. Function inlining is a compiler optimization which has no impact on the semantics. A function behaves the same whether it's inlined or not.

On the other hand, lambda functions are purely a semantic concept. There is no requirement on how they should be implemented or executed, as long as they follow the behavior set out in the language spec. They can be inlined if the JIT compiler feels like it, or not if it doesn't.

There is no inline keyword in C#, because it's an optimization that can usually be left to the compiler, especially in JIT'ed languages. The JIT compiler has access to runtime statistics which enables it to decide what to inline much more efficiently than you can when writing the code. A function will be inlined if the compiler decides to, and there's nothing you can do about it either way. :)

Use a different tool. Something like Wolfram Alpha, Maple, R, Octave, Matlab or any other algebra software package.

As a beginner you should probably not attempt to solve such a non-trivial problem.

You can take a look here for a longer list of screen sizes and respective media queries.

Or go for Bootstrap media queries:

/* Large desktop */
@media (min-width: 1200px) { ... }

/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }

/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }

/* Landscape phones and down */
@media (max-width: 480px) { ... }

Additionally you might wanty to take a look at Foundation's media queries with the following default settings:

// Media Queries

$screenSmall: 768px !default;
$screenMedium: 1279px !default;
$screenXlarge: 1441px !default;

it's :

vbnewline

for example

Msgbox ("Fst line" & vbnewline & "second line")

1. Open Reg HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\

2. make a loop to get all subkeys

3. the subkeys you are interested with are those started with [S-1-5-21-] which means user (see key name [ProfileImagePath] they are always started with a path c:\Users)

4. Those starting with [S-1-5-21-12] are all local users

5. Those starting with [S-1-5-21-13] are all network users [if joined to Domained network] that are previously logged on the machine.

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

In case you're having this problem in flex/adobe air and find yourself here first, i've found a solution, and have posted it on a related question: ADD COLUMN to sqlite db IF NOT EXISTS - flex/air sqlite?

My comment here: https://stackoverflow.com/a/24928437/2678219

There is also:

try:
    del mydict[key]
except KeyError:
    pass

This only does 1 lookup instead of 2. However, except clauses are expensive, so if you end up hitting the except clause frequently, this will probably be less efficient than what you already have.

Here is the official word on this from MS.

http://support.microsoft.com/kb/2531482

Their solution is the same as above, install the SQL Server 2008 R2 updates with the version 10.50.1777.0.

httpOnly cookie flag support in PHP 5.2

As stated in that article, you can set the header yourself in previous versions of PHP

header("Set-Cookie: hidden=value; httpOnly");

Install pip as described here: How do I install pip on Windows?

Then do

pip install flask

That installation tutorial is a bit misleading, it refers to actually running it in a production environment.

something like

for (int rows = 0; rows < dataGrid.Rows.Count; rows++)
{
     for (int col= 0; col < dataGrid.Rows[rows].Cells.Count; col++)
    {
        string value = dataGrid.Rows[rows].Cells[col].Value.ToString();

    }
} 

example without using index

foreach (DataGridViewRow row in dataGrid.Rows)
{ 
    foreach (DataGridViewCell cell in row.Cells)
    {
        string value = cell.Value.ToString();

    }
}

Try string manipulation:

var txt = "I expect five hundred dollars ($500). and new brackets ($600)";
var newTxt = txt.split('(');
for (var i = 1; i < newTxt.length; i++) {
    console.log(newTxt[i].split(')')[0]);
}

or regex (which is somewhat slow compare to the above)

var txt = "I expect five hundred dollars ($500). and new brackets ($600)";
var regExp = /\(([^)]+)\)/g;
var matches = txt.match(regExp);
for (var i = 0; i < matches.length; i++) {
    var str = matches[i];
    console.log(str.substring(1, str.length - 1));
}

I just now searched for this as I'm in a similar situation, and instead of kill -9 698 I tried sudo kill 428 where 428 was the pid of the process I'm trying to kill. It worked cleanly for me, in the absence of the hyphen '-' character. I hope it helps!

The question is old, but still receives a lot of attention. As the existing answers are outdated, here a more up-to-date solution:

Resizing local images

As of knitr 1.12, there is the function include_graphics. From ?include_graphics (emphasis mine):

The major advantage of using this function is that it is portable in the sense that it works for all document formats that knitr supports, so you do not need to think if you have to use, for example, LaTeX or Markdown syntax, to embed an external image. Chunk options related to graphics output that work for normal R plots also work for these images, such as out.width and out.height.

Example:

```{r, out.width = "400px"}
knitr::include_graphics("path/to/image.png")
```

Advantages:

• Over agastudy's answer: No need for external libraries or for re-rastering the image.
• Over Shruti Kapoor's answer: No need to manually write HTML. Besides, the image is included in the self-contained version of the file.

Including generated images

To compose the path to a plot that is generated in a chunk (but not included), the chunk options opts_current$get("fig.path") (path to figure directory) as well as opts_current$get("label") (label of current chunk) may be useful. The following example uses fig.path to include the second of two images which were generated (but not displayed) in the first chunk:

```{r generate_figures, fig.show = "hide"}
library(knitr)
plot(1:10, col = "green")
plot(1:10, col = "red")
```

```{r}
include_graphics(sprintf("%sgenerate_figures-2.png", opts_current$get("fig.path")))
```

The general pattern of figure paths is [fig.path]/[chunklabel]-[i].[ext], where chunklabel is the label of the chunk where the plot has been generated, i is the plot index (within this chunk) and ext is the file extension (by default png in RMarkdown documents).

you can use the <pre> tag to prevent multiple spaces and linebreaks from being collapsed into one. Or you could use   for a typical space (non-breaking space) and <br /> (or <br>) for line breaks.

But don't do <br><br><br><br> just use a <p> tag and adjust the margins with CSS.

<p style="margin-top: 20px;">Some copy...</p>

Although, you should define the styles globally, and not inline as I have done in this example.

When you are outputting strings from PHP you can use "\n" for a new line, and "\t" for a tab.

<?php echo "This is one line\nThis is another line"; ?>

Although, flags like \n or \t only work in double quotes (") not single wuotes (').

x is the target angle. y is the source or starting angle:

atan2(sin(x-y), cos(x-y))

It returns the signed delta angle. Note that depending on your API the order of the parameters for the atan2() function might be different.

Was playing with this today... I beleive you can also use @@ROWCOUNT, like this:

DECLARE @SQL VARCHAR(50)
DECLARE @Rowcount INT
SET @SQL = 'SELECT 1 UNION SELECT 2'
EXEC(@SQL)
SET @Rowcount = @@ROWCOUNT
SELECT @Rowcount

Then replace the 'SELECT 1 UNION SELECT 2' with your actual select without the count. I'd suggest just putting 1 in your select, like this:

SELECT 1
FROM dbo.Comm_Services
WHERE....
....

(as opposed to putting SELECT *)

Hope that helps.

Next time, use a single "alter table" statement to update the primary key.

alter table xx drop primary key, add primary key(k1, k2, k3);

To fix things:

create table fixit (user_2, user_1, type, timestamp, n, primary key( user_2, user_1, type) );
lock table fixit write, user_interactions u write, user_interactions write;

insert into fixit 
select user_2, user_1, type, max(timestamp), count(*) n from user_interactions u 
group by user_2, user_1, type
having n > 1;

delete u from user_interactions u, fixit 
where fixit.user_2 = u.user_2 
  and fixit.user_1 = u.user_1 
  and fixit.type = u.type 
  and fixit.timestamp != u.timestamp;

alter table user_interactions add primary key (user_2, user_1, type );

unlock tables;

The lock should stop further updates coming in while your are doing this. How long this takes obviously depends on the size of your table.

The main problem is if you have some duplicates with the same timestamp.

CREATE TABLE User (
user_id INT NOT NULL AUTO_INCREMENT,
userName VARCHAR(100) NOT NULL,
password VARCHAR(255) NOT NULL,
email VARCHAR(255) NOT NULL,
userImage  LONGBLOB NOT NULL, 
Favorite VARCHAR(255) NOT NULL,
PRIMARY KEY (user_id)
);

and

CREATE TABLE Event (
    EventID INT NOT NULL AUTO_INCREMENT, 
    PRIMARY KEY (EventID),
    EventName VARCHAR(100) NOT NULL,
    EventLocation VARCHAR(100) NOT NULL,
    EventPriceRange VARCHAR(100) NOT NULL,
    EventDate Date NOT NULL,
    EventTime Time NOT NULL,
    EventDescription VARCHAR(255) NOT NULL,
    EventCategory VARCHAR(255) NOT NULL,
    EventImage  LONGBLOB NOT NULL,     
    index(EventID),
    FOREIGN KEY (EventID) REFERENCES User(user_id)
);

You can use StringEscapeUtils from Apache Commons Logging utility or escape manually using code for each character.

I had a similar problem in that I was getting LINK1181 errors on the .OBJ file that was part of the project itself (and there were only 2 .cxx files in the entire project).

Initially I had setup the project to generate an .EXE in Visual Studio, and then in the Property Pages -> Configuration Properties -> General -> Project Defaults -> Configuration Type, I changed the .EXE to .DLL. Suspecting that somehow Visual Studio 2008 was getting confused, I recreated the entire solution from scratch using .DLL mode right from the start. Problem went away after that. I imagine if you manually picked your way through the .vcproj and other related files you could figure out how to fix things without starting from scratch (but my program consisted of two .cpp files so it was easier to start over).

I only have a workaround here. In this special case, I would use the FILTER function instead of QUERY:

=FILTER(Responses!B:B,Responses!G:G=B1)

Assuming that your data is on the "Responses" sheet, but your condition (cell reference) is in the actual sheet's B1 cell.

Hope it helps.

UPDATE:

After some search for the original question: The problem with your formula is definitely the second & sign which assumes that you would like to concatenate something more to your WHERE statement. Try to remove it. If it still doesn't work, then try this:

=QUERY(Responses!B1:I, "Select B where G matches '^.\*($" & B1 & ").\*$'") - I have not tried it, but it helped in another post: Query with range of values for WHERE clause?

uchar * value = img2.data; //Pointer to the first pixel data ,it's return array in all values 
int r = 2;
for (size_t i = 0; i < img2.cols* (img2.rows * img2.channels()); i++)
{

        if (r > 2) r = 0;

        if (r == 0) value[i] = 0;
        if (r == 1)value[i] =  0;
        if (r == 2)value[i] = 255;

        r++;
}

in c# this is working :D

protect void button1_Click(object sender, EventArgs e){
    button2_Click(button2, null);
}

protect void button2_Click(object sender, EventeArgs e){
    //some codes here
}

for vb.net

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)   Handles Button1.Click
    Button2_Click(Sender, e)
End Sub

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)   Handles Button2.Click
    //some codes here
End Sub

You can also check with composer:

composer show laravel/framework

It used to be installed with the .NET framework. MsBuild v12.0 (2013) is now bundled as a stand-alone utility and has it's own installer.

http://www.microsoft.com/en-us/download/confirmation.aspx?id=40760

To reference the location of MsBuild.exe from within an MsBuild script, use the default $(MsBuildToolsPath) property.

This should be the simplest solution.

Note this is a MacOS question and this answer works only for MacOS. It does not work on iOS.

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

My silly mistake was this: change != to ==

if(convertView != null) { // <---- HERE 
                LayoutInflater layoutInflater = LayoutInflater.from(z_selBoardElectricity.this);
                convertView = layoutInflater.inflate(R.layout.listview_board_alert, null);

                TextView textView = convertView.findViewById(R.id.board_name_tv);
                ImageView imageView = convertView.findViewById(R.id.board_imageview);

                textView.setText(text_list.get(position));
                imageView.setImageDrawable(imageAddressList.get(position));

                convertView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent = new Intent();
                        intent.putExtra("MESSAGE", text_list.get(pos));
                        setResult(98, intent);
                        finish();
                    }
                });
            }
return convertView;

var object = {
    key1 : {
        name : 'xxxxxx',
        value : '100.0'
    },
    key2 : {
        name : 'yyyyyyy',
        value : '200.0'
    },
    key3 : {
        name : 'zzzzzz',
        value : '500.0'
    },
}

If thats how your object looks and you want to loop each name and value then I would try and do something like.

$.each(object,function(key,innerjson){
    /*
        key would be key1,key2,key3
        innerjson would be the name and value **
    */

    //Alerts and logging of the variable.
    console.log(innerjson); //should show you the value    
    alert(innerjson.name); //Should say xxxxxx,yyyyyy,zzzzzzz
});

Lawrence has given you a good answer. But if you want more control over what gets exported to where in Excel see Modules: Sample Excel Automation - cell by cell which is slow and Modules: Transferring Records to Excel with Automation You can do things such as export the recordset starting in row 2 and insert custom text in row 1. As well as any custom formatting required.

I saw one example that uses Import/Export-CLIXML.

These are my favorite commands for the issue you're trying to resolve. And the simplest way to use them is.

$passwordPath = './password.txt'
if (-not (test-path $passwordPath)) {
    $cred = Get-Credential -Username domain\username -message 'Please login.'
    Export-CliXML -InputObject $cred -Path $passwordPath
}
$cred = Import-CliXML -path $passwordPath

So if the file doesn't locally exist it will prompt for the credentials and store them. This will take a [pscredential] object without issue and will hide the credentials as a secure string.

Finally just use the credential like you normally do.

Restart-Computer -ComputerName ... -Credentail $cred

Note on Securty:

Securely store credentials on disk

When reading the Solution, you might at first be wary of storing a password on disk. While it is natural (and prudent) to be cautious of littering your hard drive with sensitive information, the Export-CliXml cmdlet encrypts credential objects using the Windows standard Data Protection API. This ensures that only your user account can properly decrypt its contents. Similarly, the ConvertFrom-SecureString cmdlet also encrypts the password you provide.

Edit: Just reread the original question. The above will work so long as you've initialized the [pscredential] to the hard disk. That is if you drop that in your script and run the script once it will create that file and then running the script unattended will be simple.

The problem lies in https.conf file!

# Virtual hosts
# Include conf/extra/httpd-vhosts.conf

The error occurs when hash(#) is removed or messed around with. These two lines should appear as shown above.

If you do want to use null values with '=' or '<>' operators you may find the

answer from @egallardo hier

very useful.

Short example for '=': The expression

WHERE t.field = :param

you refactor like this

WHERE ((:param is null and t.field is null) or t.field = :param)

Now you can set the parameter param either to some non-null value or to null:

query.setParameter("param", "Hello World"); // Works
query.setParameter("param", null);          // Works also

If your path contains space then try using %~s1. This will remove the space and appends ~1 to your path and more importantly it refers to the absolute path of your file. Try using it.

To delete a normal stash created with git stash , you want git stash drop or git stash drop stash@{n}. See below for more details.

You don't need to delete a stash created with git stash create. From the docs:

Create a stash entry (which is a regular commit object) and return its object name, without storing it anywhere in the ref namespace. This is intended to be useful for scripts. It is probably not the command you want to use; see "save" above.

Since nothing references the stash commit, it will get garbage collected eventually.

A stash created with git stash or git stash save is saved to refs/stash, and can be deleted with git stash drop. As with all Git objects, the actual stash contents aren't deleted from your computer until a gc prunes those objects after they expire (default is 2 weeks later).

Older stashes are saved in the refs/stash reflog (try cat .git/logs/refs/stash), and can be deleted with git stash drop stash@{n}, where n is the number shown by git stash list.

You can try this

 public static Object[] addTwoArray(Object[] objArr1, Object[] objArr2){
    int arr1Length = objArr1!=null && objArr1.length>0?objArr1.length:0;
    int arr2Length = objArr2!=null && objArr2.length>0?objArr2.length:0;
    Object[] resutlentArray = new Object[arr1Length+arr2Length]; 
    for(int i=0,j=0;i<resutlentArray.length;i++){
        if(i+1<=arr1Length){
            resutlentArray[i]=objArr1[i];
        }else{
            resutlentArray[i]=objArr2[j];
            j++;
        }
    }

    return resutlentArray;
}

U can type cast your array !!!

Like this

png('filename.png')
# make plot
dev.off()

or this

# sometimes plots do better in vector graphics
svg('filename.svg')
# make plot
dev.off()

or this

pdf('filename.pdf')
# make plot
dev.off()

And probably others too. They're all listed together in the help pages.

For those using autocmd, it is a best practice to group those together. If a grouping is related to file-type detection, you might have something like this:

augroup filetype_c
    autocmd!
    :autocmd FileType c setlocal tabstop=2 shiftwidth=2 softtabstop=2 expandtab
    :autocmd FileType c nnoremap <buffer> <localleader>c I/*<space><esc><s-a><space>*/<esc>
augroup end

Groupings help keep the .vimrc organized especially once a filetype has multiple rules associated with it. In the above example, a comment shortcut specific to .c files is defined.

The initial call to autocmd! tells vim to delete any previously defined autocommands in said grouping. This will prevent duplicate definition if .vimrc is sourced again. See the :help augroup for more info.

It works, when you use both lines:

Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"

Something in the lines of

myString.split("\\s+");

This groups all white spaces as a delimiter.

So if I have the string:

"Hello[space character][tab character]World"

This should yield the strings "Hello" and "World" and omit the empty space between the [space] and the [tab].

As VonC pointed out, the backslash should be escaped, because Java would first try to escape the string to a special character, and send that to be parsed. What you want, is the literal "\s", which means, you need to pass "\\s". It can get a bit confusing.

The \\s is equivalent to [ \\t\\n\\x0B\\f\\r].

Use a parameter array with the params modifier:

public static int AddUp(params int[] values)
{
    int sum = 0;
    foreach (int value in values)
    {
        sum += value;
    }
    return sum;
}

If you want to make sure there's at least one value (rather than a possibly empty array) then specify that separately:

public static int AddUp(int firstValue, params int[] values)

(Set sum to firstValue to start with in the implementation.)

Note that you should also check the array reference for nullity in the normal way. Within the method, the parameter is a perfectly ordinary array. The parameter array modifier only makes a difference when you call the method. Basically the compiler turns:

int x = AddUp(4, 5, 6);

into something like:

int[] tmp = new int[] { 4, 5, 6 };
int x = AddUp(tmp);

You can call it with a perfectly normal array though - so the latter syntax is valid in source code as well.

The . operator is for direct member access.

object.Field

The arrow dereferences a pointer so you can access the object/memory it is pointing to

pClass->Field

For red lines an points

plt.plot(dates, values, '.r-') 

or for x markers and blue lines

plt.plot(dates, values, 'xb-')

May be?

result.map(&:attributes)

If you need symbols keys:

result.map { |r| r.attributes.symbolize_keys }

Python variables are scoped to the innermost function, class, or module in which they're assigned. Control blocks like if and while blocks don't count, so a variable assigned inside an if is still scoped to a function, class, or module.

(Implicit functions defined by a generator expression or list/set/dict comprehension do count, as do lambda expressions. You can't stuff an assignment statement into any of those, but lambda parameters and for clause targets are implicit assignment.)

INSERT
INTO    remotedblink.remotedatabase.remoteschema.remotetable
SELECT  *
FROM    mytable

There is no such thing as "the end of the table" in relational databases.

You can try to do something like:

textView.getBackground().setAlpha(51);

Here you can set the opacity between 0 (fully transparent) to 255 (completely opaque). The 51 is exactly the 20% you want.

`Parent: child process 248 exited with status 1073807364 -- Restarting.`

Add the following in the httpd.conf file of xampp to resolve this.

<IfModule mpm_winnt_module>

</IfModule>

Another option is to create an extra wrapper to center the element vertically.

One fast solution is set image property for image1 and set backgroundimage property to imag2, the only inconvenience is that you have the two images inside the picture box, but you can change background properties to tile, streched, etc. Make sure that backcolor be transparent. Hope this helps

I like Zarembisty's answer. Although, if you want to be more explicit, you can always do:

if len(my_list) == 0:
    print "my_list is empty"

What I really needed for this was something like this:

for i in $(the_array); do something; done

For instance:

for i in $(ps -aux | grep vlc  | awk '{ print $2 }'); do kill -9 $i; done

(Would kill all processes with vlc in their name)

On macOS, none of the answers worked for me. I discovered that was due to differences in how sed works on macOS and other BSD systems compared to GNU.

In particular BSD sed takes the -i option but requires a suffix for the backup (but an empty suffix is permitted)

grep version from this answer.

grep -rl 'foo' ./ | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

find version from this answer.

find . \( ! -regex '.*/\..*' \) -type f | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

Don't omit the Regex to ignore . folders if you're in a Git repo. I realized that the hard way!

That LC_ALL=C option is to avoid getting sed: RE error: illegal byte sequence if sed finds a byte sequence that is not a valid UTF-8 character. That's another difference between BSD and GNU. Depending on the kind of files you are dealing with, you may not need it.

For some reason that is not clear to me, the grep version found more occurrences than the find one, which is why I recommend to use grep.

If you want to match an expression starting with [ and ending with ], use \[[^\]]*\].

I see the picture, and all your classes are in the same package. So you don't have to import, you can create a new instance without the import sentence.

var results = from DataRow myRow in myDataTable.Rows
    where (int)myRow["RowNo"] == 1
    select myRow

Thanks to João Paulo Oliveira, this was my solution which includes a variable (which was my goal).

document.getElementById( "myID" ).setAttribute( "onClick", "myFunction("+VALUE+");" );

split (from GNU coreutils, since version 8.8 from 2010-12-22) includes the following parameter:

-n, --number=CHUNKS     generate CHUNKS output files; see explanation below

CHUNKS may be:
  N       split into N files based on size of input
  K/N     output Kth of N to stdout
  l/N     split into N files without splitting lines/records
  l/K/N   output Kth of N to stdout without splitting lines/records
  r/N     like 'l' but use round robin distribution
  r/K/N   likewise but only output Kth of N to stdout

Thus, split -n 4 input output. will generate four files (output.a{a,b,c,d}) with the same amount of bytes, but lines might be broken in the middle.

If we want to preserve full lines (i.e. split by lines), then this should work:

split -n l/4 input output.

Place your css in the following script and paste it into your CSS file.

@media screen and (-webkit-min-device-pixel-ratio:0) { your complete css style }

For example: @media screen and (-webkit-min-device-pixel-ratio:0) { container { margin-top: 120px;} }

Works like a charm.

I think this is more readable given the intent:

$('someTableSelector').children( 'tr:not(:first)' ).remove();

Using children also takes care of the case where the first row contains a table by limiting the depth of the search.

If you had an TBODY element, you can do this:

$("someTableSelector > tbody:last").children().remove();

If you have THEAD or TFOOT elements you'll need to do something different.

All the answers here are super helpful but miss one very weird bug about Jenkins. After you have edited the new job configurations, sometimes if your zoom level is too high, you may not see the save or apply button option. The button is present on the page and hidden by your zoom level, you have to zoom out until you see the button at the bottom left of your page.

Strange, I know!

Your activity must have

public void insertIntoDb(View v) {
...
} 

not Fragment .

If you don't want the above in activity. initialize button in fragment and set listener to the same.

<Button
    android:id="@+id/btn_conferma" // + missing

Then

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

   View view = inflater.inflate(R.layout.fragment_rssitem_detail,
    container, false);
   Button button = (Button) view.findViewById(R.id.btn_conferma);
   button.setOnClickListener(new OnClickListener()
   {
             @Override
             public void onClick(View v)
             {
                // do something
             } 
   }); 
   return view;
}

var payeeCountry = document.getElementById( "payeeCountry" );
alert( payeeCountry.options[ yourSelect.selectedIndex ].value );

Yes, and basically you can also use inline style:

<span style="font-size: 15px" class="glyphicon glyphicon-cog"></span>

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

What about using an extension method?

public static bool AnyOrNotNull<T>(this IEnumerable<T> source)
{
  if (source != null && source.Any())
    return true;
  else
    return false;
}

try this:

legend.green-color a:hover{
    text-decoration: none;
}

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

I did a little experiment to see which of these methods

• string.startswith('hello')
• string.rfind('hello') == 0
• string.rpartition('hello')[0] == ''
• string.rindex('hello') == 0

are most efficient to return whether a certain string begins with another string.

Here is the result of one of the many test runs I've made, where each list is ordered to show the least time it took (in seconds) to parse 5 million of each of the above expressions during each iteration of the while loop I used:

['startswith: 1.37', 'rpartition: 1.38', 'rfind: 1.62', 'rindex: 1.62']
['startswith: 1.28', 'rpartition: 1.44', 'rindex: 1.67', 'rfind: 1.68']
['startswith: 1.29', 'rpartition: 1.42', 'rindex: 1.63', 'rfind: 1.64']
['startswith: 1.28', 'rpartition: 1.43', 'rindex: 1.61', 'rfind: 1.62']

['startswith: 1.34', 'rpartition: 1.43', 'rfind: 1.64', 'rindex: 1.64']
['startswith: 1.36', 'rpartition: 1.44', 'rindex: 1.61', 'rfind: 1.63']
['startswith: 1.29', 'rpartition: 1.37', 'rindex: 1.64', 'rfind: 1.67']
['startswith: 1.34', 'rpartition: 1.44', 'rfind: 1.66', 'rindex: 1.68']
['startswith: 1.44', 'rpartition: 1.41', 'rindex: 1.61', 'rfind: 2.24']

['startswith: 1.32', 'rpartition: 1.39', 'rfind: 1.64', 'rindex: 1.61']
['rpartition: 1.35', 'startswith: 1.36', 'rfind: 1.63', 'rindex: 1.67']
['startswith: 1.29', 'rpartition: 1.36', 'rfind: 1.65', 'rindex: 1.84']

['startswith: 1.38', 'rpartition: 1.48', 'rfind: 1.68', 'rindex: 1.68']
['startswith: 1.35', 'rpartition: 1.42', 'rfind: 1.63', 'rindex: 1.68']
['startswith: 1.32', 'rpartition: 1.46', 'rfind: 1.65', 'rindex: 1.75']
['startswith: 1.37', 'rpartition: 1.46', 'rfind: 1.74', 'rindex: 1.75']
['startswith: 1.31', 'rpartition: 1.48', 'rfind: 1.67', 'rindex: 1.74']
['startswith: 1.44', 'rpartition: 1.46', 'rindex: 1.69', 'rfind: 1.74']
['startswith: 1.44', 'rpartition: 1.42', 'rfind: 1.65', 'rindex: 1.65']
['startswith: 1.36', 'rpartition: 1.44', 'rfind: 1.64', 'rindex: 1.74']
['startswith: 1.34', 'rpartition: 1.46', 'rfind: 1.61', 'rindex: 1.74']
['startswith: 1.35', 'rpartition: 1.56', 'rfind: 1.68', 'rindex: 1.69']
['startswith: 1.32', 'rpartition: 1.48', 'rindex: 1.64', 'rfind: 1.65']
['startswith: 1.28', 'rpartition: 1.43', 'rfind: 1.59', 'rindex: 1.66']

I believe that it is pretty obvious from the start that the startswith method would come out the most efficient, as returning whether a string begins with the specified string is its main purpose.

What surprises me is that the seemingly impractical string.rpartition('hello')[0] == '' method always finds a way to be listed first, before the string.startswith('hello') method, every now and then. The results show that using str.partition to determine if a string starts with another string is more efficient then using both rfind and rindex.

Another thing I've noticed is that string.rindex('hello') == 0 and string.rindex('hello') == 0 have a good battle going on, each rising from fourth to third place, and dropping from third to fourth place, which makes sense, as their main purposes are the same.

Here is the code:

from time import perf_counter

string = 'hello world'
places = dict()

while True:
    start = perf_counter()
    for _ in range(5000000):
        string.startswith('hello')
    end = perf_counter()
    places['startswith'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rfind('hello') == 0
    end = perf_counter()
    places['rfind'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rpartition('hello')[0] == ''
    end = perf_counter()
    places['rpartition'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rindex('hello') == 0
    end = perf_counter()
    places['rindex'] = round(end - start, 2)
    
    print([f'{b}: {str(a).ljust(4, "4")}' for a, b in sorted(i[::-1] for i in places.items())])

Its faster with MUTT command

echo "Body Of the Email"  | mutt -a "File_Attachment.csv" -s "Daily Report for $(date)"  -c [email protected] [email protected] -y

1. -c email cc list
2. -s subject list
3. -y to send the mail

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

How do you run a program all by itself without an operating system running?

You place your binary code to a place where processor looks for after rebooting (e.g. address 0 on ARM).

Can you create assembly programs that the computer can load and run at startup ( e.g. boot the computer from a flash drive and it runs the program that is on the drive)?

General answer to the question: it can be done. It's often referred to as "bare metal programming". To read from flash drive, you want to know what's USB, and you want to have some driver to work with this USB. The program on this drive would also have to be in some particular format, on some particular filesystem... This is something that boot loaders usually do, but your program could include its own bootloader so it's self-contained, if the firmware will only load a small block of code.

Many ARM boards let you do some of those things. Some have boot loaders to help you with basic setup.

Here you may find a great tutorial on how to do a basic operating system on a Raspberry Pi.

Edit: This article, and the whole wiki.osdev.org will anwer most of your questions http://wiki.osdev.org/Introduction

Also, if you don't want to experiment directly on hardware, you can run it as a virtual machine using hypervisors like qemu. See how to run "hello world" directly on virtualized ARM hardware here.

try this..

<tr ng-repeat='item in items'>
<td>{{item.Name}}</td>
<td>{{item.Price}}</td>
<td>{{item.Quantity}}</td>
</tr>

<td class="first"> <?php echo $proxy ?> </td> is inside a literal string that you are echoing. End the string, or concatenate it correctly:

<td class="first">' . $proxy . '</td>

I ran into this problem because I had multiple wildcard entries for the same ports. You can easily check this by executing apache2ctl -S:

# apache2ctl -S
[Wed Oct 22 18:02:18 2014] [warn] _default_ VirtualHost overlap on port 30000, the first has precedence
[Wed Oct 22 18:02:18 2014] [warn] _default_ VirtualHost overlap on port 20001, the first has precedence
VirtualHost configuration:
11.22.33.44:80       is a NameVirtualHost
         default server xxx.com (/etc/apache2/sites-enabled/xxx.com.conf:1)
         port 80 namevhost xxx.com (/etc/apache2/sites-enabled/xxx.com.conf:1)
         [...]
11.22.33.44:443      is a NameVirtualHost
         default server yyy.com (/etc/apache2/sites-enabled/yyy.com.conf:37)
         port 443 namevhost yyy.com (/etc/apache2/sites-enabled/yyy.com.conf:37)
wildcard NameVirtualHosts and _default_ servers:
*:80                   hostname.com (/etc/apache2/sites-enabled/000-default:1)
*:20001                hostname.com (/etc/apache2/sites-enabled/000-default:33)
*:30000                hostname.com (/etc/apache2/sites-enabled/000-default:57)
_default_:443          hostname.com (/etc/apache2/sites-enabled/default-ssl:2)
*:20001                hostname.com (/etc/apache2/sites-enabled/default-ssl:163)
*:30000                hostname.com (/etc/apache2/sites-enabled/default-ssl:178)
Syntax OK

Notice how at the beginning of the output are a couple of warning lines. These will indicate which ports are creating the problems (however you probably already knew that).

Next, look at the end of the output and you can see exactly which files and lines the virtualhosts are defined that are creating the problem. In the above example, port 20001 is assigned both in /etc/apache2/sites-enabled/000-default on line 33 and /etc/apache2/sites-enabled/default-ssl on line 163. Likewise *:30000 is listed in 2 places. The solution (in my case) was simply to delete one of the entries.

You can use git rebase --interactive, using the edit command on the commit you want to amend.

You may wonder, why the syntax is valid (but not working as expected):

var func = p => { foo: "bar" }

It's because of JavaScript's label syntax:

So if you transpile the above code to ES5, it should look like:

var func = function (p) {
  foo:
  "bar"; //obviously no return here!
}

Solution: You must explicitly add the parameter -CAfile your-ca-file.pem.

Note: I tried also param -CApath mentioned in another answers, but is does not works for me.

Explanation: Error unable to get local issuer certificate means, that the openssl does not know your root CA cert.

Note: If you have web server with more domains, do not forget to add also -servername your.domain.net parameter. This parameter will "Set TLS extension servername in ClientHello". Without this parameter, the response will always contain the default SSL cert (not certificate, that match to your domain).

Clearing a list in place will affect all other references of the same list.

For example, this method doesn't affect other references:

>>> a = [1, 2, 3]
>>> b = a
>>> a = []
>>> print(a)
[]
>>> print(b)
[1, 2, 3]

But this one does:

>>> a = [1, 2, 3]
>>> b = a
>>> del a[:]      # equivalent to   del a[0:len(a)]
>>> print(a)
[]
>>> print(b)
[]
>>> a is b
True

You could also do:

>>> a[:] = []

The quick start guide that keyboardsurfer references will work if you need to get your project to build properly, but it leaves you with a dummy google-play-services project in your Eclipse workspace, and it doesn't properly link Eclipse to the Google Play Services Javadocs.

Here's what I did instead:

1. Install the Google Play Services SDK using the instructions in the Android Maps V2 Quick Start referenced above, or the instructions to Setup Google Play Services SDK, but do not follow the instructions to add Google Play Services into your project.

2. Right click on the project in the Package Explorer, select Properties to open the properties for your project.

3. (Only if you already followed the instructions in the quick start guide!) Remove the dependency on the google-play-services project:

   • Click on the Android category and remove the reference to the google-play-services project.

   • Click on the Java Build Path category, then the Projects tab and remove the reference to the google-play-services project.

4. Click on the Java Build Path category, then the Libraries tab.

5. Click Add External JARs... and select the google-play-services.jar file. This should be in [Your ADT directory]\sdk\extras\google\google_play_services\libproject\google-play-services_lib\libs.

6. Click on the arrow next to the new google-play-services.jar entry, and select the Javadoc Location item.

7. Click Edit... and select the folder containing the Google Play Services Javadocs. This should be in [Your ADT directory]\sdk\extras\google\google_play_services\docs\reference.

8. Still in the Java Build Path category, click on the Order and Export tab. Check the box next to the google-play-services.jar entry.

9. Click OK to save your project properties.

Your project should now have access to the Google Play Services library, and the Javadocs should display properly in Eclipse.

You can access the $_SERVER['DOCUMENT_ROOT'] variable :

<?php 
   $path = $_SERVER['DOCUMENT_ROOT'];
   $path .= "/subdir1/yourdocument.txt";
?>

Thumbs up first before use codes please!!! Create an image that fully cover the whole tab bar item for each item. This is needed to use the image you created as a tab bar item button. Be sure to make the height/width ratio be the same of each tab bar item too. Then:

UITabBarController *tabBarController = (UITabBarController *)self;
UITabBar *tabBar = tabBarController.tabBar;
UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];
UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3];

int x,y;

x = tabBar.frame.size.width/4 + 4; //when doing division, it may be rounded so that you need to add 1 to each item; 
y = tabBar.frame.size.height + 10; //the height return always shorter, this is compensated by added by 10; you can change the value if u like.

//because the whole tab bar item will be replaced by an image, u dont need title
tabBarItem1.title = @"";
tabBarItem2.title = @"";

Hi modified version of another post by Marecki. Has 4 styles

1. dots ....
2  10 to 1 count down
3. progress bar (default)
4. just percentage.

Before you ask why I didn't edit that post is I did and it got rejected was told to post a new answer.

Sub ShowProgress()

  Const x As Long = 150000
  Dim i&, PB$

  For i = 1 To x
  DoEvents
  UpdateProgress i, x
  Next i

  Application.StatusBar = ""
End Sub 'ShowProgress

Sub UpdateProgress(icurr As Long, imax As Long, Optional istyle As Integer = 3)
    Dim PB$
    PB = Format(icurr / imax, "00 %")
    If istyle = 1 Then ' text dots >>....    <<'
        Application.StatusBar = "Progress: " & PB & "  >>" & String(Val(PB), Chr(183)) & String(100 - Val(PB), Chr(32)) & "<<"
    ElseIf istyle = 2 Then ' 10 to 1 count down  (eight balls style)
        Application.StatusBar = "Progress: " & PB & "  " & ChrW$(10111 - Val(PB) / 11)
    ElseIf istyle = 3 Then ' solid progres bar (default)
        Application.StatusBar = "Progress: " & PB & "  " & String(100 - Val(PB), ChrW$(9608))
    Else ' just 00 %
        Application.StatusBar = "Progress: " & PB
    End If
End Sub

if everything is ok, just add ->unsigned(); at the end of foregin key.

if it does not work, check the datatype of both fields. they must be the same.

simplify @Vikas version

@Override
public boolean onPrepareOptionsMenu (Menu menu) {

    menu.findItem(R.id.example_foobar).setEnabled(isFinalized);
    return true;
}

I think that access() function, which is found in unistd.h is a good choice for Linux (you can use stat too).

You can Use it like this:

#include <stdio.h>
#include <stdlib.h>
#include<unistd.h>

void fileCheck(const char *fileName);

int main (void) {
    char *fileName = "/etc/sudoers";

    fileCheck(fileName);
    return 0;
}

void fileCheck(const char *fileName){

    if(!access(fileName, F_OK )){
        printf("The File %s\t was Found\n",fileName);
    }else{
        printf("The File %s\t not Found\n",fileName);
    }

    if(!access(fileName, R_OK )){
        printf("The File %s\t can be read\n",fileName);
    }else{
        printf("The File %s\t cannot be read\n",fileName);
    }

    if(!access( fileName, W_OK )){
        printf("The File %s\t it can be Edited\n",fileName);
    }else{
        printf("The File %s\t it cannot be Edited\n",fileName);
    }

    if(!access( fileName, X_OK )){
        printf("The File %s\t is an Executable\n",fileName);
    }else{
        printf("The File %s\t is not an Executable\n",fileName);
    }
}

And you get the following Output:

The File /etc/sudoers    was Found
The File /etc/sudoers    cannot be read
The File /etc/sudoers    it cannot be Edited
The File /etc/sudoers    is not an Executable

cursor.execute(sql,array)

Only takes two arguments.
It will iterate the "array"-object and match ? in the sql-string.
(with sanity checks to avoid sql-injection)

For a very simple case like this, a comprehension, as in Ismail Badawi's answer is definitely the way to go.

But when things get more complicated, and you need to start writing multi-clause or nested comprehensions with complex expressions in them, it's worth looking into other alternatives. There are a few different (quasi-)standard ways to specify XPath-style searches on nested dict-and-list structures, such as JSONPath, DPath, and KVC. And there are nice libraries on PyPI for them.

Here's an example with the library named dpath, showing how it can simplify something just a bit more complicated:

>>> dd = {
...     'fruits': [{'value': 'apple', 'blah': 2}, {'value': 'banana', 'blah': 3}],
...     'vehicles': [{'value': 'cars', 'blah':4}]}

>>> {key: [{'value': d['value']} for d in value] for key, value in dd.items()}
{'fruits': [{'value': 'apple'}, {'value': 'banana'}],
 'vehicles': [{'value': 'cars'}]}

>>> dpath.util.search(dd, '*/*/value')
{'fruits': [{'value': 'apple'}, {'value': 'banana'}],
 'vehicles': [{'value': 'cars'}]}

Or, using jsonpath-ng:

>>> [d['value'] for key, value in dd.items() for d in value]
['apple', 'banana', 'cars']
>>> [m.value for m in jsonpath_ng.parse('*.[*].value').find(dd)]
['apple', 'banana', 'cars']

This one may not look quite as simple at first glance, because find returns match objects, which include all kinds of things besides just the matched value, such as a path directly to each item. But for more complex expressions, being able to specify a path like '*.[*].value' instead of a comprehension clause for each * can make a big difference. Plus, JSONPath is a language-agnostic specification, and there are even online testers that can be very handy for debugging.

If you truly want to discard the commits you've made locally, i.e. never have them in the history again, you're not asking how to pull - pull means merge, and you don't need to merge. All you need do is this:

# fetch from the default remote, origin
git fetch
# reset your current branch (master) to origin's master
git reset --hard origin/master

I'd personally recommend creating a backup branch at your current HEAD first, so that if you realize this was a bad idea, you haven't lost track of it.

If on the other hand, you want to keep those commits and make it look as though you merged with origin, and cause the merge to keep the versions from origin only, you can use the ours merge strategy:

# fetch from the default remote, origin
git fetch
# create a branch at your current master
git branch old-master
# reset to origin's master
git reset --hard origin/master
# merge your old master, keeping "our" (origin/master's) content
git merge -s ours old-master

The specification for 'mailto' body says:

The body of a message is simply lines of US-ASCII characters. The only two limitations on the body are as follows:

• CR and LF MUST only occur together as CRLF; they MUST NOT appear independently in the body.
• Lines of characters in the body MUST be limited to 998 characters, and SHOULD be limited to 78 characters, excluding the CRLF.

https://tools.ietf.org/html/rfc5322#section-2.3

Generally nowadays most email clients are good at autolinking, but not all do, due to security concerns. You can likely find some work-arounds, but it won't necessarily work universally.

Suppress logs using standard python library 'logging'

Place this code on the top of your existing code

import logging
urllib3_logger = logging.getLogger('urllib3')
urllib3_logger.setLevel(logging.CRITICAL)

Swift 3 - Days from today until date

func daysUntilDate(endDateComponents: DateComponents) -> Int
    {
        let cal = Calendar.current
        var components = cal.dateComponents([.era, .year, .month, .day], from: NSDate() as Date)
        let today = cal.date(from: components)
        let otherDate = cal.date(from: endDateComponents)

        components = cal.dateComponents([Calendar.Component.day], from: (today! as Date), to: otherDate!)
        return components.day!
    }

Call function like this

// Days from today until date
   var examnDate = DateComponents()
   examnDate.year = 2016
   examnDate.month = 12
   examnDate.day = 15
   let daysCount = daysUntilDate(endDateComponents: examnDate)

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

Found a graceful solution.

echo ${LINE//12345678/$replace}

Just use the == with the negation symbol (!). If dtfm is the name of your data.frame:

dtfm[!dtfm$C == "Foo", ]

Or, to move the negation in the comparison:

dtfm[dtfm$C != "Foo", ]

Or, even shorter using subset():

subset(dtfm, C!="Foo")

One possible C loop would be:

#include <stdio.h>
int main()
{
    int c;
    while ((c = getchar()) != EOF)
    {
        /*
        ** Do something with c, such as check against '\n'
        ** and increment a line counter.
        */
    }
}

For now, I would ignore feof and similar functions. Exprience shows that it is far too easy to call it at the wrong time and process something twice in the belief that eof hasn't yet been reached.

Pitfall to avoid: using char for the type of c. getchar returns the next character cast to an unsigned char and then to an int. This means that on most [sane] platforms the value of EOF and valid "char" values in c don't overlap so you won't ever accidentally detect EOF for a 'normal' char.

Don't use String.prototype.toCamelCase() because String.prototypes are read-only, most of the js compilers will give you this warning.

Like me, those who know that the string will always contains only one space can use a simpler approach:

let name = 'test string';

let pieces = name.split(' ');

pieces = pieces.map((word, index) => word.charAt(0)[index===0 ? 'toLowerCase' :'toUpperCase']() + word.toLowerCase().slice(1));

return pieces.join('');

Have a good day. :)

Use column selection. Column selection is one of the unique features of Sublime2; it is used to give you multiple matched cursors (tutorial here). To get multiple cursors, do one of the following:

Mouse:

• Hold down the shift (Windows/Linux) or option key (Mac) while selecting a region with the mouse.

• Clicking middle mouse button (or scroll) will select as a column also.

Keyboard:

• Select the desired region.
• Type control+shift+L (Windows/Linux) or command+shift+L (Mac)

You now have multiple lines selected, so you could type a quotation mark at the beginning and end of each line. It would be better to take advantage of Sublime's capabilities, and just type ". When you do this, Sublime automatically quotes the selected text.

Type esc to exit multiple cursor mode.

The solution with TextBoxFor is OK, but if you don't want to see the field like EditBox stylish (it might be a little confusing for the user) involve changes as follows:

1. Razor code before changes

   <div class="editor-field">
        @Html.EditorFor(model => model.Text)
        @Html.ValidationMessageFor(model => model.Text)
   </div>
   

2. After changes

   <!-- New div display-field (after div editor-label) -->
   <div class="display-field">
       @Html.DisplayFor(model => model.Text)
   </div>
   
   <div class="editor-field">
       <!-- change to HiddenFor in existing div editor-field -->
       @Html.HiddenFor(model => model.Text)
       @Html.ValidationMessageFor(model => model.Text)
   </div>
   

Generally, this solution prevents field from editing, but shows value of it. There is no need for code-behind modifications.

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

From GNU Make error appendix, as you see this is not a Make error but an error coming from gcc.

‘[foo] Error NN’ ‘[foo] signal description’ These errors are not really make errors at all. They mean that a program that make invoked as part of a recipe returned a non-0 error code (‘Error NN’), which make interprets as failure, or it exited in some other abnormal fashion (with a signal of some type). See Errors in Recipes. If no *** is attached to the message, then the subprocess failed but the rule in the makefile was prefixed with the - special character, so make ignored the error.

So in order to attack the problem, the error message from gcc is required. Paste the command in the Makefile directly to the command line and see what gcc says. For more details on Make errors click here.

If your browser supports CSS3, try using the CSS element Calc()

height: calc(100% - 65px);

you might also want to adding browser compatibility options:

height: -o-calc(100% - 65px); /* opera */
height: -webkit-calc(100% - 65px); /* google, safari */
height: -moz-calc(100% - 65px); /* firefox */

also make sure you have spaces between values, see: https://stackoverflow.com/a/16291105/427622

@Inherently Curious - thanks for posting this. You are almost there - you have to add two more params to SSLContext.init() method.

TrustManager[] trustManagers = new TrustManager[] { new TrustManagerManipulator() };
sc.init(null, trustManagers, new SecureRandom());

it will start working. Again thank you very much for posting this. I solved this/my issue with your code.

The only character that needs escaping is <. (> is meaningless outside of a tag).

Therefore, your "magic" code is:

safestring = unsafestring.replace(/</g,'&lt;');

First find out your PHP version. In my case 5.6.

Then:

sudo yum search mcrypt

And choose the best one for your version from the list, I used php56w-mcrypt.

Use:

Write "Stuff to write" | Out-File Outputfile.txt -Append

Your code does work (tested with cpython 2.4, 2.5, 2.6, 2.7, 3.1 and 3.2):

>>> a = set(["Blah", "Hello"])
>>> a = list(a) # You probably wrote a = list(a()) here or list = set() above
>>> a
['Blah', 'Hello']

Check that you didn't overwrite list by accident:

>>> assert list == __builtins__.list

Yes, cmake and make are different programs. cmake is (on Linux) a Makefile generator (and Makefile-s are the files driving the make utility). There are other Makefile generators (in particular configure and autoconf etc...). And you can find other build automation programs (e.g. ninja).

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

Before you start, go to the directory "phpMyAdmin" preferably the one in your localhost, clear all of your cookies, and have your sql running by entering:

sudo /usr/local/mysql/support-files/mysql.server start

To fix the error , you will have to run the following commands in your terminal:

export PATH=$PATH:/usr/local/mysql/bin/

then:

mysql -u root

after which, you'll need to change your permissions inside the mySQL shell:

UPDATE user SET Password=PASSWORD('YOURNEWPASSWORD') WHERE User='root'; FLUSH PRIVILEGES; exit;

Refresh your phpMyAdmin window, re-enter the "root" username (or whichever is applicable), and your password and you should be good to go. Check http://machiine.com/2013/how-to-setup-phpmyadmin-on-a-mac-with-osx-10-8-mamp-part-3/ if you are willing to set up from scratch.

I was using Visual Studio Code.

1) Try to install the package 'Microsoft.EntityFrameworkCore.SqlServer' by specifying the version number.

VS Code:

'dotnet add package Microsoft.EntityFrameworkCore.SqlServer -v 1.1.1'

Visual Studio:-

'Install-Package Microsoft.EntityFrameworkCore.SqlServer -v 1.1.1'

Refer the link 'Package 'Microsoft.EntityFrameworkCore.SqlServer' is incompatible with 'all' frameworks in the project' for doing it.

2) Then add the namespace 'using Microsoft.EntityFrameworkCore;' manually in the Startup.cs file.

Refer the below link https://github.com/aspnet/EntityFramework/issues/7891.

3) If you get any dependency issue for 'Microsoft.EntityFrameworkCore.SqlServer.Design', like "Package 'Microsoft.EntityFrameworkCore.Design' is incompatible with 'all' frameworks in project" ,we need to run the below command,

VS Code:-

dotnet add package Microsoft.EntityFrameworkCore.Design -v 1.1

Visual Studio

Install-Package Microsoft.EntityFrameworkCore.Design -v 1.1

Try this

$('input:checkbox:checked').click(function(){
    var val=(this).val(); // it will get value from checked checkbox;
})

Here flag is true if checked otherwise false

var flag=$('#ans').attr('checked');

Again this will make cheked

$('#ans').attr('checked',true);

From PowerShell remove force answer: help Remove-Item says:

An app is available that demonstrates a listview that combines both swiping-to-delete and dragging to reorder items. The code is based on Chet Haase's code for swiping-to-delete and Daniel Olshansky's code for dragging-to-reorder.

Chet's code deletes an item immediately. I improved on this by making it function more like Gmail where swiping reveals a bottom view that indicates that the item is deleted but provides an Undo button where the user has the possibility to undo the deletion. Chet's code also has a bug in it. If you have less items in the listview than the height of the listview is and you delete the last item, the last item appears to not be deleted. This was fixed in my code.

Daniel's code requires pressing long on an item. Many users find this unintuitive as it tends to be a hidden function. Instead, I modified the code to allow for a "Move" button. You simply press on the button and drag the item. This is more in line with the way the Google News app works when you reorder news topics.

The source code along with a demo app is available at: https://github.com/JohannBlake/ListViewOrderAndSwipe

Chet and Daniel are both from Google.

A considerable amount of work went into gluing all this together to provide a seemless UI experience, so I'd appreciate a Like or Up Vote. Please also star the project in Github.

Mostly the default shortcut key combination is Ctrl + Alt + Left/Right. (I'm using the linux version)

Or you can have a toolbar option for it. Enable the tool bar by View -> Toolbar. The Left and Right Arrows will do the same. If you hover over it then you can see the shortcut key combination also.

Just in case the key combination is not working (this can be due to several reasons like you are using a virtual machine, etc) you can change this default key combination, or you can add an extra combination (ex: For Back/Move to previous Ctrl + Alt + < or Comma).

Go to Settings -> select keymap (type keymap in the search bar) -> **Editor Actions -> search for back and find Navigate options -> change the settings as you prefer.

Mixing plyr::mutate and dplyr::case_when works for me and is readable.

iris %>%
plyr::mutate(coolness =
     dplyr::case_when(Species  == "setosa"     ~ "not cool",
                      Species  == "versicolor" ~ "not cool",
                      Species  == "virginica"  ~ "super awesome",
                      TRUE                     ~ "undetermined"
       )) -> testIris
head(testIris)
levels(testIris$coolness)  ## NULL
testIris$coolness <- as.factor(testIris$coolness)
levels(testIris$coolness)  ## ok now
testIris[97:103,4:6]

Bonus points if the column can come out of mutate as a factor instead of char! The last line of the case_when statement, which catches all un-matched rows is very important.

     Petal.Width    Species      coolness
 97         1.3  versicolor      not cool
 98         1.3  versicolor      not cool  
 99         1.1  versicolor      not cool
100         1.3  versicolor      not cool
101         2.5  virginica     super awesome
102         1.9  virginica     super awesome
103         2.1  virginica     super awesome

According to the switch statement documentation if there is an unambiguous way to implicitly convert the the object to an integral type, then it will be allowed. I think you are expecting a behavior where for each case statement it would be replaced with if (t == typeof(int)), but that would open a whole can of worms when you get to overload that operator. The behavior would change when implementation details for the switch statement changed if you wrote your == override incorrectly. By reducing the comparisons to integral types and string and those things that can be reduced to integral types (and are intended to) they avoid potential issues.

func getCurrentTimeZone() -> String {
        let localTimeZoneAbbreviation: Int = TimeZone.current.secondsFromGMT()
        let gmtAbbreviation = (localTimeZoneAbbreviation / 60)
        return "\(gmtAbbreviation)"
}

You can get current time zone abbreviation.

I had to source my bash_profile file. To do so,

1. Open up a Terminal session.
2. In that session type: source .bash_profile and then press enter

Now, the gcloud command should work

You can get the property the same way as you set it.

foo = {
 bar: "value"
}

You set the value foo["bar"] = "baz";

To get the value foo["bar"]

will return "baz".

First of all, beware of that method:

As Jesse Ezel says:

Brad Abrams

"The method might seem convenient, but most of the time I have found that this situation arises from trying to cover up deeper bugs.

Your code should stick to a particular protocol on the use of strings, and you should understand the use of the protocol in library code and in the code you are working with.

The NullOrEmpty protocol is typically a quick fix (so the real problem is still somewhere else, and you got two protocols in use) or it is a lack of expertise in a particular protocol when implementing new code (and again, you should really know what your return values are)."

And if you patch String class... be sure NilClass has not been patch either!

class NilClass
    def empty?; true; end
end

in the "global and static" area :)

There are several memory areas in C++:

• heap
• free store
• stack
• global & static
• const

See here for a detailed answer to your question:

The following summarizes a C++ program's major distinct memory areas. Note that some of the names (e.g., "heap") do not appear as such in the draft [standard].

     Memory Area     Characteristics and Object Lifetimes
     --------------  ------------------------------------------------

     Const Data      The const data area stores string literals and
                     other data whose values are known at compile
                     time.  No objects of class type can exist in
                     this area.  All data in this area is available
                     during the entire lifetime of the program.

                     Further, all of this data is read-only, and the
                     results of trying to modify it are undefined.
                     This is in part because even the underlying
                     storage format is subject to arbitrary
                     optimization by the implementation.  For
                     example, a particular compiler may store string
                     literals in overlapping objects if it wants to.


     Stack           The stack stores automatic variables. Typically
                     allocation is much faster than for dynamic
                     storage (heap or free store) because a memory
                     allocation involves only pointer increment
                     rather than more complex management.  Objects
                     are constructed immediately after memory is
                     allocated and destroyed immediately before
                     memory is deallocated, so there is no
                     opportunity for programmers to directly
                     manipulate allocated but uninitialized stack
                     space (barring willful tampering using explicit
                     dtors and placement new).


     Free Store      The free store is one of the two dynamic memory
                     areas, allocated/freed by new/delete.  Object
                     lifetime can be less than the time the storage
                     is allocated; that is, free store objects can
                     have memory allocated without being immediately
                     initialized, and can be destroyed without the
                     memory being immediately deallocated.  During
                     the period when the storage is allocated but
                     outside the object's lifetime, the storage may
                     be accessed and manipulated through a void* but
                     none of the proto-object's nonstatic members or
                     member functions may be accessed, have their
                     addresses taken, or be otherwise manipulated.


     Heap            The heap is the other dynamic memory area,
                     allocated/freed by malloc/free and their
                     variants.  Note that while the default global
                     new and delete might be implemented in terms of
                     malloc and free by a particular compiler, the
                     heap is not the same as free store and memory
                     allocated in one area cannot be safely
                     deallocated in the other. Memory allocated from
                     the heap can be used for objects of class type
                     by placement-new construction and explicit
                     destruction.  If so used, the notes about free
                     store object lifetime apply similarly here.


     Global/Static   Global or static variables and objects have
                     their storage allocated at program startup, but
                     may not be initialized until after the program
                     has begun executing.  For instance, a static
                     variable in a function is initialized only the
                     first time program execution passes through its
                     definition.  The order of initialization of
                     global variables across translation units is not
                     defined, and special care is needed to manage
                     dependencies between global objects (including
                     class statics).  As always, uninitialized proto-
                     objects' storage may be accessed and manipulated
                     through a void* but no nonstatic members or
                     member functions may be used or referenced
                     outside the object's actual lifetime.

ArrayAdapter<String> should work.

i.e.:

Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>
            (this, android.R.layout.simple_spinner_item,
           spinnerArray); //selected item will look like a spinner set from XML
spinnerArrayAdapter.setDropDownViewResource(android.R.layout
                                                     .simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter); 

Use the PropertyConfigurator: PropertyConfigurator.configure(configFileUrl);

I benefited a lot from 'Dive into HTML 5'. The explanation and demo are easier and to the point. History chapter - http://diveintohtml5.info/history.html and history demo - http://diveintohtml5.info/examples/history/fer.html

The same can be done without DataTrigger too:

 <DataGrid.RowStyle>
     <Style TargetType="DataGridRow">
         <Setter Property="Background" >
             <Setter.Value>
                 <Binding Path="State" Converter="{StaticResource BooleanToBrushConverter}">
                     <Binding.ConverterParameter>
                         <x:Array Type="SolidColorBrush">
                             <SolidColorBrush Color="{StaticResource RedColor}"/>
                             <SolidColorBrush Color="{StaticResource TransparentColor}"/>
                         </x:Array>
                     </Binding.ConverterParameter>
                 </Binding>
             </Setter.Value>
         </Setter>
     </Style>
 </DataGrid.RowStyle>

Where BooleanToBrushConverter is the following class:

public class BooleanToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value == null)
            return Brushes.Transparent;

        Brush[] brushes = parameter as Brush[];
        if (brushes == null)
            return Brushes.Transparent;

        bool isTrue;
        bool.TryParse(value.ToString(), out isTrue);

        if (isTrue)
        {
            var brush =  (SolidColorBrush)brushes[0];
            return brush ?? Brushes.Transparent;
        }
        else
        {
            var brush = (SolidColorBrush)brushes[1];
            return brush ?? Brushes.Transparent;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

git checkout {branch-name} -- {file-name}

This will use the file from the branch of choice.

I like this because posh-git autocomplete works great with this. It also removes any ambiguity as to which branch is remote and which is local. And --theirs didn't work for me anyways.

Late joining this conversation to shed light on a mildly interesting factoid for web-facing, analytics-aware websites. Passing the mic over to Michael Papworth:

https://github.com/michaelpapworth/jQuery.navigate

"When using website analytics, window.location is not sufficient due to the referer not being passed on the request. The plugin resolves this and allows for both aliased and parametrised URLs."

If one examines the code what it does is this:

   var methods = {
            'goTo': function (url) {
                // instead of using window.location to navigate away
                // we use an ephimeral link to click on and thus ensure
                // the referer (current url) is always passed on to the request
                $('<a></a>').attr("href", url)[0].click();
            },
            ...
   };

Neato!

You can access it by the class' private attributes:

cls_name = self.__class__.__name__

EDIT:

As said by Ned Batcheler, this wouldn't work in the class body, but it would in a method.

In Kotlin, if you don't want to create an extra class just for setting one value, you can create anonymous class from LayoutManager:

recyclerView.layoutManager = object : LinearLayoutManager(context) {
    override fun canScrollVertically(): Boolean = false
}

As Rutesh and jmservera pointed out, the distinction is a fuzzy one. Historically, they were different, but through the 90's these two previously distinct categories blended features and effectively merged. At this point is is probably best to imagine that the "App Server" product category is a strict superset of the "web server" category.

Some history. In early days of the Mosaic browser and hyperlinked content, there evolved this thing called a "web server" that served web page content and images over HTTP. Most of the content was static, and the HTTP 1.0 protocol was just a way to ship files around. Quickly the "web server" category evolved to include CGI capability - effectively launching a process on each web request to generate dynamic content. HTTP also matured and the products became more sophisticated, with caching, security, and management features. As the technology matured, we got company-specific Java-based server-side technology from Kiva and NetDynamics, which eventually all merged into JSP. Microsoft added ASP, I think in 1996, to Windows NT 4.0. The static web server had learned some new tricks, so that it was an effective "app server" for many scenarios.

In a parallel category, the app server had evolved and existed for a long time. companies delivered products for Unix like Tuxedo, TopEnd, Encina that were philosophically derived from Mainframe application management and monitoring environments like IMS and CICS. Microsoft's offering was Microsoft Transaction Server (MTS), which later evolved into COM+. Most of these products specified "closed" product-specific communications protocols to interconnect "fat" clients to servers. (For Encina, the comms protocol was DCE RPC; for MTS it was DCOM; etc.) In 1995/96, these traditional app server products began to embed basic HTTP communication capability, at first via gateways. And the lines began to blur.

Web servers got more and more mature with respect to handling higher loads, more concurrency, and better features. App servers delivered more and more HTTP-based communication capability.

At this point the line between "app server" and "web server" is a fuzzy one. But people continue to use the terms differently, as a matter of emphasis. When someone says "web server" you often think HTTP-centric, web UI, oriented apps. When someone says "App server" you may think "heavier loads, enterprise features, transactions and queuing, multi-channel communication (HTTP + more). But often it is the same product that serves both sets of workload requirements.

• WebSphere, IBM's "app server" has its own bundled web server.
• WebLogic, another traditional app server, likewise.
• Windows, which is Microsoft's App Server (in addition to being its File&Print Server, Media Server, etc.), bundles IIS.

Choose Database | Set Datasource Location... Select the database node (yellow-ish cylinder) of the current connection, then select the database node of the desired connection (you may need to authenticate), then click Update.

You will need to do this for the 'Subreports' nodes as well.

FYI, you can also do individual tables by selecting each individually, then choosing Update.

Here is a simple example:

    package main

    import "fmt"

    func plusTwo() (func(v int) (int)) {
        return func(v int) (int) {
            return v+2
        }
    }

    func plusX(x int) (func(v int) (int)) {
       return func(v int) (int) {
           return v+x
       }
    }

    func main() {
        p := plusTwo()
        fmt.Printf("3+2: %d\n", p(3))

        px := plusX(3)
        fmt.Printf("3+3: %d\n", px(3))
    }

You can use the sp_who stored procedure.

Provides information about current users, sessions, and processes in an instance of the Microsoft SQL Server Database Engine. The information can be filtered to return only those processes that are not idle, that belong to a specific user, or that belong to a specific session.

I have tried to manage this issue via below steps :

Delete android { ... } block in top level root gradle file

Look into

 compileSdkVersion 22
 buildToolsVersion "22.0.0"

lines of code in app/gradle file here only one of the version persent in below dropdown should be present else it would give provide option to downloaad the same.

You can use Bundle to do the same in Android

Create the intent:

Intent i = new Intent(this, ActivityTwo.class);
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
String getrec=textView.getText().toString();

//Create the bundle
Bundle bundle = new Bundle();

//Add your data to bundle
bundle.putString(“stuff”, getrec);

//Add the bundle to the intent
i.putExtras(bundle);

//Fire that second activity
startActivity(i);

Now in your second activity retrieve your data from the bundle:

//Get the bundle
Bundle bundle = getIntent().getExtras();

//Extract the data…
String stuff = bundle.getString(“stuff”); 

As the commenters for the previous answer mentioned, you cannot simply add the line...

<location path="." inheritInChildApplications="false">

...just below <configuration>. Instead, you need to wrap the individual web.config sections for which you want to disable inheritance. For example:

<!-- disable inheritance for the connectionStrings section -->
<location path="." inheritInChildApplications="false">
   <connectionStrings>
   </connectionStrings>
</location>

<!-- leave inheritance enabled for appSettings -->
<appSettings>
</appSettings>

<!-- disable inheritance for the system.web section -->
<location path="." inheritInChildApplications="false">
   <system.web>
        <webParts>
        </webParts>
        <membership>
        </membership>

        <compilation>
        </compilation>
      </system.web>
 </location>

While <clear /> may work for some configuration sections, there are some that instead require a <remove name="..."> directive, and still others don't seem to support either. In these situations, it's probably appropriate to set inheritInChildApplications="false".

Here is one more alternative that uses XSL transformations for more complex email templates: Sending HTML-based email from .NET applications.

In my opinion the better way is to do this with the Parameters property of the SqlCommand class:

public static void AddCommandParameter(SqlCommand myCommand)
{
    myCommand.Parameters.AddWithValue(
        "@AgeIndex",
        (AgeItem.AgeIndex== null) ? DBNull.Value : AgeItem.AgeIndex);
}

I have used the jQuery-condense-plugin before, which looks like it can do what you want. If not, there are different plugins that might suit your needs.

Edit: Made you a demo - note that I linked the jquery.condense.js on the demo which does the magic, so full credit to the author of that plugin :)

An old thread, but a useful one... so here's some additional code.

First, in response to Craig's point about the regex being overly greedy and failing for sheet names containing a single quote, this should do the trick (replace 'SHEETNAME'!A1 with your own sheet & cell reference):

=IF(TODAY()=TODAY(), SUBSTITUTE(REGEXREPLACE(CELL("address",'SHEETNAME'!A1),"'?(.+?)'?!\$.*","$1"),"''","'", ""), "")

It uses a lazy match (the ".+?") to find a character string (squotes included) that may or may not be enclosed by squotes but is definitely terminated by bang dollar ("!$") followed by any number of characters. Google Sheets actually protects squotes within a sheet name by appending another squote (as in ''), so the SUBSTITUTE is needed to reduce these back to single squotes.

The formula also allows for sheet names that contain bangs ("!"), but will fail for names using bang dollars ("!$") - if you really need to make your sheet names to look like full absolute cell references then put a separating character between the bang and the dollar (such as a space).

Note that it will only work correctly when pointed at a different sheet from the one that the formula resides! This is because CELL("address" returns just the cell reference (not the sheet name) when used on the same sheet. If you need a sheet to show its own name then put the formula in a cell on another sheet, point it at your target sheet, and then reference the formula cell from the target sheet. I often have a "Meta" sheet in my workbooks to hold settings, common values, database matching criteria, etc so that's also where I put this formula.

As others have said many times above, Google Sheets will only notice changes to the sheet name if you set the workbook's recalculation to "On change and every minute" which you can find on the File|Settings|Calculation menu. It can take up to a whole minute for the change to be picked up.

Secondly, if like me you happen to need an inter-operable formula that works on both Google Sheets and Excel (which for older versions at least doesn't have the REGEXREPLACE function), try:

=IF(IFERROR(INFO("release"), 0)=0, IF(TODAY()=TODAY(), SUBSTITUTE(REGEXREPLACE(CELL("address",'SHEETNAME'!A1),"'?(.+?)'?!\$.*","$1"),"''","'", ""), ""), MID(CELL("filename",'SHEETNAME'!A1),FIND("]",CELL("filename",'SHEETNAME'!A1))+1,255))

This uses INFO("release") to determine which platform we are on... Excel returns a number >0 whereas Google Sheets does not implement the INFO function and generates an error which the formula traps into a 0 and uses for numerical comparison. The Google code branch is as above.

For clarity and completeness, this is the Excel-only version (which does correctly return the name of the sheet it resides on):

=MID(CELL("filename",'SHEETNAME'!A1),FIND("]",CELL("filename",'SHEETNAME'!A1))+1,255)

It looks for the "]" filename terminator in the output of CELL("filename" and extracts the sheet name from the remaining part of the string using the MID function. Excel doesn't allow sheet names to contain "]" so this works for all possible sheet names. In the inter-operable version, Excel is happy to be fed a call to the non-existent REGEXREPLACE function because it never gets to execute the Google code branch.

EF Core 2.1+ :

Property:

public string[] Strings { get; set; }

OnModelCreating:

modelBuilder.Entity<YourEntity>()
            .Property(e => e.Strings)
            .HasConversion(
                v => string.Join(',', v),
                v => v.Split(',', StringSplitOptions.RemoveEmptyEntries));

Update (2021-02-14)

The PostgreSQL has an array data type and the Npgsql EF Core provider does support that. So it will map your C# arrays and lists to the PostgreSQL array data type automatically and no extra config is required. Also you can operate on the array and the operation will be translated to SQL.

More information on this page.

String newString = originalString.substring(originalString.length()-3);

Even after installing python-tk, python3-tk I was getting error your python is not configured for Tk.

So I additionally installed tk8.6-dev Then I build my Python again, run following again: make, make install.

When I did this I saw messages on screen that it is building _tkinter and related modules. Once that is done, I tried 'import tkinter" and it worked.

Your thread's locale is set to one in which the decimal mark is "," instead of ".".

Try using this:

float.Parse("41.00027357629127", CultureInfo.InvariantCulture.NumberFormat);

Note, however, that a float cannot hold that many digits of precision. You would have to use double or Decimal to do so.

You should use the flex or flex-basis property rather than width. Read more on MDN.

.flexbox .red {
  flex: 0 0 25em;
}

The flex CSS property is a shorthand property specifying the ability of a flex item to alter its dimensions to fill available space. It contains:

flex-grow: 0;     /* do not grow   - initial value: 0 */
flex-shrink: 0;   /* do not shrink - initial value: 1 */
flex-basis: 25em; /* width/height  - initial value: auto */

A simple demo shows how to set the first column to 50px fixed width.

.flexbox {_x000D_
  display: flex;_x000D_
}_x000D_
.red {_x000D_
  background: red;_x000D_
  flex: 0 0 50px;_x000D_
}_x000D_
.green {_x000D_
  background: green;_x000D_
  flex: 1;_x000D_
}_x000D_
.blue {_x000D_
  background: blue;_x000D_
  flex: 1;_x000D_
}

<div class="flexbox">_x000D_
  <div class="red">1</div>_x000D_
  <div class="green">2</div>_x000D_
  <div class="blue">3</div>_x000D_
</div>

See the updated codepen based on your code.

This got bumped to the top because of an edit ... The answers have gotten a bit stale, and not as useful today as another solution has been added to the standard.

There is now an "all" shorthand property.

#elementId select.funTimes {
   all: initial;
}

This sets all css properties to their initial value ... note some of the initial values are inherit; Resulting in some formatting still taking place on the element.

Because of that pause required when reading the code or reviewing it in the future, don't use it unless you most as the review process is a point where errors/bugs can be made! when editing the page. But clearly if there are a large number of properties that need to be reset, then "all" is the way to go.

Standard is online here: https://drafts.csswg.org/css-cascade/#all-shorthand

You can find a few examples here:

// Fill the DataSet.
DataSet ds = new DataSet();
ds.Locale = CultureInfo.InvariantCulture;
FillDataSet(ds);

DataTable contacts = ds.Tables["Contact"];
DataTable orders = ds.Tables["SalesOrderHeader"];

var query =
    contacts.AsEnumerable().Join(orders.AsEnumerable(),
    order => order.Field<Int32>("ContactID"),
    contact => contact.Field<Int32>("ContactID"),
    (contact, order) => new
    {
        ContactID = contact.Field<Int32>("ContactID"),
        SalesOrderID = order.Field<Int32>("SalesOrderID"),
        FirstName = contact.Field<string>("FirstName"),
        Lastname = contact.Field<string>("Lastname"),
        TotalDue = order.Field<decimal>("TotalDue")
    });


foreach (var contact_order in query)

There is a Go to member shortcut (listed in settings > shortcut > Text Editor). Open the file containing your function (in the sources panel of the DevTools) and press:

ctrl + shift + O

or in OS X:

? + shift + O

This enables to list and reach members of the current file.

Powershell also accept the C/C++/C* not operator

if ( !(Test-Path C:\Code) ){ write "it doesn't exist!" }

I use it often because I'm used to C*...
allows code compression/simplification...
I also find it more elegant...

Does Customer implement the equals() contract?

If it doesn't implement equals() and hashCode(), then listCustomer.contains(customer) will check to see if the exact same instance already exists in the list (By instance I mean the exact same object--memory address, etc). If what you are looking for is to test whether or not the same Customer( perhaps it's the same customer if they have the same customer name, or customer number) is in the list already, then you would need to override equals() to ensure that it checks whether or not the relevant fields(e.g. customer names) match.

Note: Don't forget to override hashCode() if you are going to override equals()! Otherwise, you might get trouble with your HashMaps and other data structures. For a good coverage of why this is and what pitfalls to avoid, consider having a look at Josh Bloch's Effective Java chapters on equals() and hashCode() (The link only contains iformation about why you must implement hashCode() when you implement equals(), but there is good coverage about how to override equals() too).

By the way, is there an ordering restriction on your set? If there isn't, a slightly easier way to solve this problem is use a Set<Customer> like so:

Set<Customer> noDups = new HashSet<Customer>();
noDups.addAll(tmpListCustomer);
return new ArrayList<Customer>(noDups);

Which will nicely remove duplicates for you, since Sets don't allow duplicates. However, this will lose any ordering that was applied to tmpListCustomer, since HashSet has no explicit ordering (You can get around that by using a TreeSet, but that's not exactly related to your question). This can simplify your code a little bit.

If the top commit is pointed to by HEAD then you can do something like this:

commit1 -> HEAD
commit2 -> HEAD~1
commit3 -> HEAD~2

Diff between the first and second commit:

git diff HEAD~1 HEAD

Diff between first and third commit:

git diff HEAD~2 HEAD

Diff between second and third commit:

git diff HEAD~2 HEAD~1

And so on...

I'm new to python too. Here is something that looks like will do what you want to

axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`

I believe this decides the size of the canvas.

@fooMonster article worked for me

# git ls-tree HEAD
100644 blob 55c0287d4ef21f15b97eb1f107451b88b479bffe    script.sh

As you can see the file has 644 permission (ignoring the 100). We would like to change it to 755:

# git update-index --chmod=+x script.sh

commit the changes

# git commit -m "Changing file permissions"
[master 77b171e] Changing file permissions
0 files changed, 0 insertions(+), 0 deletions(-)
mode change 100644 => 100755 script.sh

>>> text = 'lipsum'
>>> text[3:]
'sum'

See the official documentation on strings for more information and this SO answer for a concise summary of the notation.

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

This will do it to every line in the file:

:%s/$/,/

If you want to do a subset of lines instead of the whole file, you can specify them in place of the %.

One way is to do a visual select and then type the :. It will fill in :'<,'> for you, then you type the rest of it (Notice you only need to add s/$/,/)

:'<,'>s/$/,/

slate is a project that makes it very simple to use PDFMiner from a library:

>>> with open('example.pdf') as f:
...    doc = slate.PDF(f)
...
>>> doc
[..., ..., ...]
>>> doc[1]
'Text from page 2...'   

This is all i can find out. Not sure if it helps, but thought I'd add it to the mix.

WORD-WRAP

This property specifies whether the current rendered line should break if the content exceeds the boundary of the specified rendering box for an element (this is similar in some ways to the ‘clip’ and ‘overflow’ properties in intent.) This property should only apply if the element has a visual rendering, is an inline element with explicit height/width, is absolutely positioned and/or is a block element.

WORD-BREAK

This property controls the line breaking behavior within words. It is especially useful in cases where multiple languages are used within an element.

From nullptr: A Type-safe and Clear-Cut Null Pointer:

The new C++09 nullptr keyword designates an rvalue constant that serves as a universal null pointer literal, replacing the buggy and weakly-typed literal 0 and the infamous NULL macro. nullptr thus puts an end to more than 30 years of embarrassment, ambiguity, and bugs. The following sections present the nullptr facility and show how it can remedy the ailments of NULL and 0.

Add namespace

using System.Configuration;

and in place of

ConfigurationSettings.AppSettings

you should use

ConfigurationManager.AppSettings

String path = ConfigurationManager.AppSettings["configFile"];

You can modify various VM properties by adding the following configuration (see the Vagrant docs for a bit more info):

  # Configure VM Ram usage
  config.vm.customize [
                        "modifyvm", :id,
                        "--name", "Test_Environment",
                        "--memory", "1024"
                      ]

You can obtain the properties that you want to change from the documents for VirtualBox command-line options:

• http://www.virtualbox.org/manual/ch08.html#vboxmanage-modifyvm

The vagrant documentation has the section on how to change IP address:

Vagrant::Config.run do |config|
  config.vm.network :hostonly, "192.168.50.4"
end

Also you can restructure the configuration like this, ending is do with end without nesting it. This is simpler.

config.vm.define :web do |web_config|
    web_config.vm.box = "lucid32"
    web_config.vm.forward_port 80, 8080
end
web_config.vm.provision :puppet do |puppet|
    puppet.manifests_path = "manifests"
    puppet.manifest_file = "lucid32.pp"
end

You can try this:

create procedure [dbo].[get_user_names]
    @user_id_list varchar(2000), -- You can use any max length

    @username varchar (30) output
    as
    select last_name+', '+first_name 
    from user_mstr
    where user_id in (Select ID from dbo.SplitString( @user_id_list, ',') )

And here is the user defined function for SplitString:

Create FUNCTION [dbo].[SplitString]
(    
      @Input NVARCHAR(MAX),
      @Character CHAR(1)
)
RETURNS @Output TABLE (
      Item NVARCHAR(1000)
)
AS
BEGIN
      DECLARE @StartIndex INT, @EndIndex INT

      SET @StartIndex = 1
      IF SUBSTRING(@Input, LEN(@Input) - 1, LEN(@Input)) <> @Character
      BEGIN
            SET @Input = @Input + @Character
      END

      WHILE CHARINDEX(@Character, @Input) > 0
      BEGIN
            SET @EndIndex = CHARINDEX(@Character, @Input)

            INSERT INTO @Output(Item)
            SELECT SUBSTRING(@Input, @StartIndex, @EndIndex - 1)

            SET @Input = SUBSTRING(@Input, @EndIndex + 1, LEN(@Input))
      END

      RETURN
END

Example #1:

class A{
 void met(){
   Class.forName("com.example.Class1");
 }
}

If com/example/Class1 doesn't exist in any of the classpaths, then It throws ClassNotFoundException.

Example #2:

Class B{
  void met(){
   com.example.Class2 c = new com.example.Class2();
 }
}

If com/example/Class2 existed while compiling B, but not found while execution, then It throws NoClassDefFoundError.

Both are run time exceptions.

In my case, I discovered that the major issue why my eclipse won't connect to internet is my Internet Service Provider. I was only able to browse some websites but unable to browse other website. Fixing the issue with the ISP worked.

Application.CutCopyMode = False

I have noticed that when using type="image/vnd.microsoft.icon", the favicon fails to appear when the browser is not connected to the internet. But type="image/x-icon" works whether the browser can connect to the internet, or not. When developing, at times I am not connected to the internet.

I would like to update the answers above to 2018 and say to use both VisualVM and Eclipse MAT.

How to use:

VisualVM is used for live monitoring and dump heap. You can also analyze the heap dumps there with great power, however MAT have more capabilities (such as automatic analysis to find leaks) and therefore, I read the VisualVM dump output (.hprof file) into MAT.

Get VisualVM:

Download VisualVM here: https://visualvm.github.io/

You also need to download the plugin for Intellij:

Then you'll see in intellij another 2 new orange icons:

Once you run your app with an orange one, in VisualVM you'll see your process on the left, and data on the right. Sit some time and learn this tool, it is very powerful:

Get Eclipse's Memory Analysis Tool (MAT) as a standalone:

Download here: https://www.eclipse.org/mat/downloads.php

And this is how it looks:

Hope it helps!

Accepted Answer works good.

In case of Invalid use of NULL value error, on NULL values, update all null values to default value in that column and then try to do the alter.

UPDATE foobar_data SET col = '{}' WHERE col IS NULL;

ALTER TABLE foobar_data MODIFY COLUMN col VARCHAR(255) NOT NULL DEFAULT '{}';

I have edited the function for you,

void readFile()
{
    ifstream file;
    file.open ("program.txt");
    if (!file.is_open()) return;

    string word;
    while (file >> word)
    {
        cout<< word << '\n';
    }
}

I think you can use Padding like: Hope this one can help you.

.loginButton {
    background:url(images/loginBtn-center.jpg) repeat-x;
    width:175px;
    height:65px;
    margin:20px auto;
    border-radius:10px;
    -webkit-border-radius:10px;
    box-shadow:0 1px 2px #5e5d5b;
    <!--Using padding to align text in box or image-->
    padding: 3px 2px;
}

I prefer this method for it's accuracy and succinctness:

var x
if (x === void 0) {
  console.log(`x is undefined`)
} else {
  console.log(`x is defined`)
}

As has been mentioned in other comments and answers, undefined isn't guaranteed to be undefined. Because it's not a keyword, it can be redefined as a variable in scopes other than the global scope. Here's little example that demonstrates this nuance:

var undefined = 'bar'
console.log(`In the global scope: ${undefined}`)

function foo() {
  var undefined = 'defined'
  var x
  if (x === undefined) {
    console.log(`x === undefined`)
  } else {
    console.log(`x !== undefined`)
  }
  if (x === void 0) {
    console.log(`x === void 0`)
  } else {
    console.log(`x !== void 0`)
  }
}

foo()

See void for compatibility (supported in IE5!?!! Wow!).

It would seem overkill but Spring Forms handles this elegantly. That is of course if you are already using Spring MVC and you want to take advantage of the Spring Forms feature.

// jsp form
    <form:select path="friendlyNumber" items="${friendlyNumberItems}" />

    // the command class
    public class NumberCmd {
      private String[] friendlyNumber;
    }

    // in your Spring MVC controller submit method
    @RequestMapping(method=RequestMethod.POST)
    public String manageOrders(@ModelAttribute("nbrCmd") NumberCmd nbrCmd){

       String[] selectedNumbers = nbrCmd.getFriendlyNumber();

    }

In my case, I was migrating from a MySQL instance with a default of MyISAM, to a MariaDB instance with a DEFAULT of InnoDB.

Per MariaDB Migration Doc's.

On old Server Run :

mysqldump -u root -p --skip-create-options --all-databases > migration.sql

The --skip-create-options ensures that the database server uses the default storage engine when loading the data, instead of MyISAM.

mysql -u root -p < migration.sql

This threw an error regarding creating mysql.db, but everything works great now :)

This regex:

(\d{1,3},\d{3}(,\d{3})*)(\.\d*)?|\d+\.?\d*

Matched every number in the string:

1 1.0 0.1 1.001 1,000 1,000,000 1000.1 1,000.1 1,323,444,000 1,999 1,222,455,666.0 1,244

If you are looking to style a file input element, look at open file dialog box in javascript. If you are looking to grab the files associated with a file input element, you must do something like this:

inputElement.onchange = function(event) {
   var fileList = inputElement.files;
   //TODO do something with fileList.  
}

See this MDN article for more info on the FileList type.

Note that the code above will only work in browsers that support the File API. For IE9 and earlier, for example, you only have access to the file name. The input element has no files property in non-File API browsers.

http://en.csharp-online.net/CSharp_FAQ:_What_are_the_differences_between_CSharp_and_Java_constant_declarations

C# constants are declared using the const keyword for compile time constants or the readonly keyword for runtime constants. The semantics of constants is the same in both the C# and Java languages.

THE way is

Their names can be a bit confusing :). Here's a summary:

• The SelectedItem property returns the entire object that your list is bound to. So say you've bound a list to a collection of Category objects (with each Category object having Name and ID properties). eg. ObservableCollection<Category>. The SelectedItem property will return you the currently selected Category object. For binding purposes however, this is not always what you want, as this only enables you to bind an entire Category object to the property that the list is bound to, not the value of a single property on that Category object (such as its ID property).

• Therefore we have the SelectedValuePath property and the SelectedValue property as an alternative means of binding (you use them in conjunction with one another). Let's say you have a Product object, that your view is bound to (with properties for things like ProductName, Weight, etc). Let's also say you have a CategoryID property on that Product object, and you want the user to be able to select a category for the product from a list of categories. You need the ID property of the Category object to be assigned to the CategoryID property on the Product object. This is where the SelectedValuePath and the SelectedValue properties come in. You specify that the ID property on the Category object should be assigned to the property on the Product object that the list is bound to using SelectedValuePath='ID', and then bind the SelectedValue property to the property on the DataContext (ie. the Product).

The example below demonstrates this. We have a ComboBox bound to a list of Categories (via ItemsSource). We're binding the CategoryID property on the Product as the selected value (using the SelectedValue property). We're relating this to the Category's ID property via the SelectedValuePath property. And we're saying only display the Name property in the ComboBox, with the DisplayMemberPath property).

<ComboBox ItemsSource="{Binding Categories}" 
          SelectedValue="{Binding CategoryID, Mode=TwoWay}" 
          SelectedValuePath="ID" 
          DisplayMemberPath="Name" />

public class Category
{
    public int ID { get; set; }
    public string Name { get; set; }
}

public class Product
{
    public int CategoryID { get; set; }
}

It's a little confusing initially, but hopefully this makes it a bit clearer... :)

Use is_null or === operator.

is_null($result['column'])

$result['column'] === NULL

In Laravel 3, call path('storage').

In Laravel 4, use the storage_path() helper function.

If you are using Guava library it's possible to do:

        SetView<Record> added = Sets.difference(secondSet, firstSet);
        SetView<Record> removed = Sets.difference(firstSet, secondSet);

And then make a conclusion based on these.

Maybe it is the case that you have your path in couple of lines, you used enter to make it? If so, then part of you paths might look like that "/\nData/" instead of "/Data/", which causes the problem. Just set it to be in one line and issue is solved!

If you load your data into ng-grid, you can use the CSV export plugin. The plugin creates a button with the grid data as csv inside an href tag.

You might read up on FILESTREAM. Here is some info from the docs that should help you decide:

If the following conditions are true, you should consider using FILESTREAM:

• Objects that are being stored are, on average, larger than 1 MB.
• Fast read access is important.
• You are developing applications that use a middle tier for application logic.

For smaller objects, storing varbinary(max) BLOBs in the database often provides better streaming performance.
