Programs & Examples On #Inno setup

Setting JAVA_HOME directory from command line worked for me!

First:

JAVA_HOME="C:\Program Files\Java\jdk1.8.0"

Or :

export JAVA_HOME="C:\Program Files\Java\jdk1.8.0"

Then try:

mvn -version

to make sure you do not get the same error. :)

This is my code, to start/stop a Windows service using SC command. If the service fails to start/stop, it will print a log info. You can try it by Inno Setup.

{ start a service }
Exec(ExpandConstant('{cmd}'), '/C sc start ServiceName', '',
     SW_HIDE, ewWaitUntilTerminated, ResultCode);
Log('sc start ServiceName:'+SysErrorMessage(ResultCode));

{ stop a service }
Exec(ExpandConstant('{cmd}'), '/C sc stop ServiceName', '',
     SW_HIDE, ewWaitUntilTerminated, ResultCode);
Log('sc stop ServiceName:'+SysErrorMessage(ResultCode));

var str = "123, 124, 234,252";
var arr = str.split(",");
for(var i=0;i<arr.length;i++) {
    arr[i] = ++arr[i];
}

My situation was similar:

• I was debugging a JUnit test
• I was using Mockito to create a spy, as in spyTask = spy(new Task())
• I put the breakpoint inside of the class that I was spying (inside Task.java)

This breakpoint generates the error in question, every time I run Debug As... > JUnit Test

To address the problem, I moved the Breakpoint 'up' into the actual test (inside TaskTest.java). Once execution stopped, I added the breakpoint back where I had it, originally (inside Task.java).

I still got the same error but after clicking "ok," the breakpoint worked just fine.

Hope that helps someone,

How about matches()?

String string = "Madam, I am Adam";

// Starts with
boolean  b = string.startsWith("Mad");  // true

// Ends with
b = string.endsWith("dam");             // true

// Anywhere
b = string.indexOf("I am") >= 0;        // true

// To ignore case, regular expressions must be used

// Starts with
b = string.matches("(?i)mad.*");

// Ends with
b = string.matches("(?i).*adam");

// Anywhere
b = string.matches("(?i).*i am.*");

Please remember one thing if you want to use bootstrap tooltip in angularjs is order of your scripts if you are using jquery-ui as well, it should be:

• jQuery
• jQuery UI
• Bootstap

It is tried and tested

You can also do this at the beginning of the query:

SET ARITHABORT OFF 
SET ANSI_WARNINGS OFF

So if you have something like 100/0 it will return NULL. I've only done this for simple queries, so I don't know how it will affect longer/complex ones.

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:

<Router>
  <Route path="/" component={App}>
    <Route path="page1" component={Page1} />
    <Route path="page2" component={Page2} />
  </Route>
  <Route path="/login" component={Login} />
</Router>

And the other components would look something like this:

var NavBar = React.createClass({
  render() {
    return (
      <div>
        <ul>
          <a onClick={() => history.push('page1') }>Page 1</a>
          <a onClick={() => history.push('page2') }>Page 2</a>
        </ul>
      </div>
    )
  }
});

var App = React.createClass({
  render() {
    return (
      <div>
        <NavBar />
        <div>Other Content</div>
        {this.props.children}
      </div>
    )
  }
});

In the official documentation states that it supports only one iterable argument. I like to use apply_async in such cases. In your case I would do:

from multiprocessing import Process, Pool, Manager

text = "test"
def harvester(text, case, q = None):
 X = case[0]
 res = text+ str(X)
 if q:
  q.put(res)
 return res


def block_until(q, results_queue, until_counter=0):
 i = 0
 while i < until_counter:
  results_queue.put(q.get())
  i+=1

if __name__ == '__main__':
 pool = multiprocessing.Pool(processes=6)
 case = RAW_DATASET
 m = Manager()
 q = m.Queue()
 results_queue = m.Queue() # when it completes results will reside in this queue
 blocking_process = Process(block_until, (q, results_queue, len(case)))
 blocking_process.start()
 for c in case:
  try:
   res = pool.apply_async(harvester, (text, case, q = None))
   res.get(timeout=0.1)
  except:
   pass
 blocking_process.join()

Above solution didn't work for me. So what I did is take ProgressDialog as globally and then add this to my activity

@Override
    protected void onDestroy() {
        if (progressDialog != null && progressDialog.isShowing())
            progressDialog.dismiss();
        super.onDestroy();
    }

so that in case if activity is destroyed then the ProgressDialog will also be destroy.

See the Express docs as well as the Node docs for https.createServer (which is what express recommends to use):

var privateKey = fs.readFileSync( 'privatekey.pem' );
var certificate = fs.readFileSync( 'certificate.pem' );

https.createServer({
    key: privateKey,
    cert: certificate
}, app).listen(port);

Other options for createServer are at: http://nodejs.org/api/tls.html#tls_tls_createserver_options_secureconnectionlistener

Use the below.

background-image: url("././images/image.png");

This shall work.

Yeah. Just use binary serialization. You have to have each object use implements Serializable but it's straightforward from there.

Your other option, if you want to avoid implementing the Serializable interface, is to use reflection and read and write data to/from a buffer using a process this one below:

/** 
 * Sets all int fields in an object to 0.
 *
 * @param obj The object to operate on.
 *
 * @throws RuntimeException If there is a reflection problem.
 */
 public static void initPublicIntFields(final Object obj) {
    try {
       Field[] fields = obj.getClass().getFields();
       for (int idx = 0; idx < fields.length; idx++) {
          if (fields[idx].getType() == int.class) {
              fields[idx].setInt(obj, 0);
          }
       }
    } catch (final IllegalAccessException ex) {
       throw new RuntimeException(ex);
    }
 }

set meta tag in head as

 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> 

use the link http://www.i18nqa.com/debug/utf8-debug.html to replace the symbols character you want.

then use str_replace like

    $find = array('“', '’', '…', '—', '–', '‘', 'é', 'Â', '•', 'Ëœ', 'â€'); // en dash
                        $replace = array('“', '’', '…', '—', '–', '‘', 'é', '', '•', '˜', '”');
$content = str_replace($find, $replace, $content);

Its the method i use and help alot. Thanks!

In addition to @enyo's answer in checking for files that are still uploading or in the queue, I also created a new function in dropzone.js to check for any files in an ERROR state (ie bad file type, size, etc).

Dropzone.prototype.getErroredFiles = function () {
    var file, _i, _len, _ref, _results;
    _ref = this.files;
    _results = [];
    for (_i = 0, _len = _ref.length; _i < _len; _i++) {
        file = _ref[_i];
        if (file.status === Dropzone.ERROR) {
            _results.push(file);
        }
    }
    return _results;
};

And thus, the check would become:

  if (this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0 && this.getErroredFiles().length === 0) {
    doSomething();
  }

In Excel, the substring function is called MID function, and indexOf is called FIND for case-sensitive location and SEARCH function for non-case-sensitive location. For the first portion of your text parsing the LEFT function may also be useful.

See all the text functions here: Text Functions (reference).

You should check provision profile is Product or Develop, if your project use multi configuration You should check configuration which called by schema, because it must make sure, your configuration was set provision Develop

Hope this will help you..

var list = [];
    $(document).ready(function () {
        $('#test').click(function () {
            var oRows = $('#MainContent_Table1 tr').length;
            $('#MainContent_Table1 tr').each(function (index) {
                list.push(this.cells[0].innerHTML);
            });
        });
    });

One way is to use sets:

>>> set([1,2,6,8]) - set([2,3,5,8])
set([1, 6])

Note, however, that sets do not preserve the order of elements, and cause any duplicated elements to be removed. The elements also need to be hashable. If these restrictions are tolerable, this may often be the simplest and highest performance option.

There is one more option and it looks quite nice. Since java 8 there is new method merge java doc

  public static void main(String[] args) {
    String s = "aaabbbcca";

    Map<Character, Integer> freqMap = new HashMap<>();
    for (int i = 0; i < s.length(); i++) {
        Character c = s.charAt(i);
        freqMap.merge(c, 1, (a, b) -> a + b);
    }
    freqMap.forEach((k, v) -> System.out.println(k + " and " + v));
}

Or even cleaner with ForEach

       for (Character c : s.toCharArray()) {
            freqMapSecond.merge(c, 1, Integer::sum);
           }

Here I am checking session values(two values filled in text box on previous page)

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["sessUnit_code"] == null || Session["sessgrcSerial"] == null)
    {
        Response.Write("<Script Language = 'JavaScript'> alert('Go to GRC Tab and fill Unit Code and GRC Serial number first')</script>");
    }
    else
    {

        lblUnit.Text = Session["sessUnit_code"].ToString();
        LblGrcSr.Text = Session["sessgrcSerial"].ToString();
    }
}

Use LINQ: Access to dictionary for the key and change the value

Dictionary<string, int> dict = new Dictionary<string, int>();
dict = dict.ToDictionary(kvp => kvp.Key, kvp => kvp.Value + 1);

This behavior is related to Zone that is set - Internet/Intranet/etc and corresponding Security Level

You can change this by setting less secure Security Level (not recommended) or by customizing Display Mixed Content property

You can do that by following steps:

1. Click on Gear icon at the top of the browser window.
2. Select Internet Options.
3. Select the Security tab at the top.
4. Click the Custom Level... button.
5. Scroll about halfway down to the Miscellaneous heading (denoted by a "blank page" icon).
6. Under this heading is the option Display Mixed Content; set this to Enable/Prompt.
7. Click OK, then Yes when prompted to confirm the change, then OK to close the Options window.
8. Close and restart the browser.

This works for me in Ansible 2.9:

variable1 = www.example.com. 
variable2 = www.example.org. 

when: ".com" in variable1

and for not:

when: not ".com" in variable2

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

You can use git add --patch <filename> (or -p for short), and git will begin to break down your file into what it thinks are sensible "hunks" (portions of the file). It will then prompt you with this question:

Stage this hunk [y,n,q,a,d,/,j,J,g,s,e,?]?

Here is a description of each option:

• y stage this hunk for the next commit
• n do not stage this hunk for the next commit
• q quit; do not stage this hunk or any of the remaining hunks
• a stage this hunk and all later hunks in the file
• d do not stage this hunk or any of the later hunks in the file
• g select a hunk to go to
• / search for a hunk matching the given regex
• j leave this hunk undecided, see next undecided hunk
• J leave this hunk undecided, see next hunk
• k leave this hunk undecided, see previous undecided hunk
• K leave this hunk undecided, see previous hunk
• s split the current hunk into smaller hunks
• e manually edit the current hunk
• ? print hunk help

If the file is not in the repository yet, you can first do git add -N <filename>. Afterwards you can go on with git add -p <filename>.

Afterwards, you can use:

• git diff --staged to check that you staged the correct changes
• git reset -p to unstage mistakenly added hunks
• git commit -v to view your commit while you edit the commit message.

Note this is far different than the git format-patch command, whose purpose is to parse commit data into a .patch files.

How to dynamically alter the minDate (after init)

The above answers address how to set the default minDate at init, but the question was actually how to dynamically alter the minDate, below I also clarify How to set the default minDate.

All that was wrong with the original question was that the minDate value being set should have been a string (don't forget the quotes):

$('#datePickerId').datepicker('option', 'minDate', '3');

minDate also accepts a date object and a common use is to have an end date you are trying to calculate so something like this could be useful:

$('#datePickerId').datepicker(
    'option', 'minDate', new Date($(".datePop.start").val())
);

How to set the default minDate (at init)

Just answering this for best practice; the minDate option expects one of:

1. a string in the current dateFormat OR
2. number of days from today (e.g. +7) OR
3. string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '-1y -1m')

@bogart setting the string to "0" is a solution as it satisfies option 2 above

$('#datePickerId').datepicker('minDate': '3');

jQuery UI docs for minDate

If you have only one value and want to get an immutable set this would be enough:

Set<String> immutableSet = Collections.singleton("a");

Don’t Repeat Your CSS

 a.abc, a.xyz{
    margin-left:20px;
 }

OR

 a{
    margin-left:20px;
 }

Single liner works

df['Name'] = 'abc'

Creates a Name column and sets all rows to abc value

After reading many questions on stackoverflow I found out that my CPU does not support Virtualization. I have to upgrade to the cpu which supports Virtualization in order to install Intel X 86 Emulator accelerator(Haxm Installer)

You have it right. The stack pointer points to the top item on the stack and the base pointer points to the "previous" top of the stack before the function was called.

When you call a function, any local variable will be stored on the stack and the stack pointer will be incremented. When you return from the function, all the local variables on the stack go out of scope. You do this by setting the stack pointer back to the base pointer (which was the "previous" top before the function call).

Doing memory allocation this way is very, very fast and efficient.

It shouldn't matter, any more than if you encoded the letter A as %41.

However, if you're dealing with a system that doesn't recognize one form, it seems like you're just going to have to give it what it expects regardless of what the "spec" says.

If you are using Spring MVC, you can add following mvn tag to exclude resources file from Spring Dispatch Servlet

<mvc:resources mapping="/js/*.js" location="/js/"/>
<mvc:resources mapping="/css/*.css" location="/css/"/>
<mvc:resources mapping="/images/*.*" location="/images/"/>

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

Sometimes it happens if you either:

1. Clean solution/build or,
2. Rebuild solution/build.

If it 'suddenly' happens after such, and your code has build-time errors then try fixing those errors first.

What happens is that as your solution is built, DLL files are created and stored in the projects bin folder. If there is an error in your code during build-time, the DLL files aren't created properly which brings up an error.

A 'quick fix' would be to fix all your errors or comment them out (if they wont affect other web pages.) then rebuild project/solution

If this doesn't work then try changing: CodeBehind="blahblahblah.aspx.cs"

to: CodeFile="blahblahblah.aspx.cs"

Note: Change "blahblahblah" to the pages real name.

As others have mentioned, and counter to what the method name would imply, writelines does not add line separators. This is a textbook case for a generator. Here is a contrived example:

def item_generator(things):
    for item in things:
        yield item
        yield '\n'

def write_things_to_file(things):
    with open('path_to_file.txt', 'wb') as f:
        f.writelines(item_generator(things))

Benefits: adds newlines explicitly without modifying the input or output values or doing any messy string concatenation. And, critically, does not create any new data structures in memory. IO (writing to a file) is when that kind of thing tends to actually matter. Hope this helps someone!

I also experience those misterious error-symbols on packages from time to time. A way to get rid of them that works for me is to effectively remove the JRE System Library from Java Build Path and add it back again.

Since MyClass is a POD class type, those non-static data members will have indeterminate initial values when you create a non-static instance of MyClass, so no, that is not a valid way to check if they have been initialized to a specific non-zero value ... you are basically assuming they will be zero-initialized, which is not going to be the case since you have not value-initialized them in a constructor.

If you want to zero-initialize your class's non-static data members, it would be best to create an initialization list and class-constructor. For example:

class MyClass
{
    void SomeMethod();

    char mCharacter;
    double mDecimal;

    public:
        MyClass();
};

MyClass::MyClass(): mCharacter(0), mDecimal(0) {}

The initialization list in the constructor above value-initializes your data-members to zero. You can now properly assume that any non-zero value for mCharacter and mDecimal must have been specifically set by you somewhere else in your code, and contain non-zero values you can properly act on.

The here-document shall be treated as a single word that begins after the next and continues until there is a line containing only the delimiter and a , with no characters in between. Then the next here-document starts, if there is one. The format is as follows:

[n]<<word
    here-document
delimiter

where the optional n represents the file descriptor number. If the number is omitted, the here-document refers to standard input (file descriptor 0).

If any character in word is quoted, the delimiter shall be formed by performing quote removal on word, and the here-document lines shall not be expanded. Otherwise, the delimiter shall be the word itself.

If no characters in word are quoted, all lines of the here-document shall be expanded for parameter expansion, command substitution, and arithmetic expansion. In this case, the in the input behaves as the inside double-quotes (see Double-Quotes). However, the double-quote character ( '"' ) shall not be treated specially within a here-document, except when the double-quote appears within "$()", "``", or "${}".

If the redirection symbol is "<<-", all leading <tab> characters shall be stripped from input lines and the line containing the trailing delimiter. If more than one "<<" or "<<-" operator is specified on a line, the here-document associated with the first operator shall be supplied first by the application and shall be read first by the shell.

When a here-document is read from a terminal device and the shell is interactive, it shall write the contents of the variable PS2, processed as described in Shell Variables, to standard error before reading each line of input until the delimiter has been recognized.

Examples

Some examples not yet given.

Quotes prevent parameter expansion

Without quotes:

a=0
cat <<EOF
$a
EOF

Output:

0

With quotes:

a=0
cat <<'EOF'
$a
EOF

or (ugly but valid):

a=0
cat <<E"O"F
$a
EOF

Outputs:

$a

Hyphen removes leading tabs

Without hyphen:

cat <<EOF
<tab>a
EOF

where <tab> is a literal tab, and can be inserted with Ctrl + V <tab>

Output:

<tab>a

With hyphen:

cat <<-EOF
<tab>a
<tab>EOF

Output:

a

This exists of course so that you can indent your cat like the surrounding code, which is easier to read and maintain. E.g.:

if true; then
    cat <<-EOF
    a
    EOF
fi

Unfortunately, this does not work for space characters: POSIX favored tab indentation here. Yikes.

According to PostgreSQL documentation (4.1.2.1. String Constants):

 To include a single-quote character within a string constant, write two 
 adjacent single quotes, e.g. 'Dianne''s horse'.

See also the standard_conforming_strings parameter, which controls whether escaping with backslashes works.

@tcaswell already answered, but I was in the middle of typing my answer up, so I'll go ahead and post it...

There are a number of different ways you could do this. To begin with, matplotlib will automatically cycle through colors. By default, it cycles through blue, green, red, cyan, magenta, yellow, black:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you want to control which colors matplotlib cycles through, use ax.set_color_cycle:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
fig, ax = plt.subplots()
ax.set_color_cycle(['red', 'black', 'yellow'])
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you'd like to explicitly specify the colors that will be used, just pass it to the color kwarg (html colors names are accepted, as are rgb tuples and hex strings):

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i, color in enumerate(['red', 'black', 'blue', 'brown', 'green'], start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

Finally, if you'd like to automatically select a specified number of colors from an existing colormap:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
number = 5
cmap = plt.get_cmap('gnuplot')
colors = [cmap(i) for i in np.linspace(0, 1, number)]

for i, color in enumerate(colors, start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

Make sure AutoSizeRowsMode is set to None else the row height won't matter because well... it'll auto-size the rows.

Should be an easy thing but I fought this for a few hours before I figured it out.

The easiest option would be to key in $. If you are working with blocks of text, you might appreciate the command { and } in order to move a paragraph back and forward, respectively.

To move and delete specific records by selecting using WHERE query,

BEGIN TRANSACTION;
Insert Into A SELECT * FROM B where URL="" AND email ="" AND Annual_Sales_Vol="" And OPENED_In="" AND emp_count=""  And contact_person= "" limit 0,2000;
delete from B where Id In (select Id from B where URL="" AND email ="" AND Annual_Sales_Vol="" And OPENED_In="" AND emp_count="" And contact_person= "" limit 0,2000);
commit;

Make sure the image exists in docker hub. To me, I was trying to pull MongoDB using the command docker run mongodb which is incorrect. In the docker hub, the image name is mongo.

Another way (depending on your actual needs): If you want to pop the first n characters and save both the popped characters and the modified string:

s = 'lipsum'
n = 3
a, s = s[:n], s[n:]
print(a)
# lip
print(s)
# sum

It is also possible, that the referenced projects targets .NET 4.0, while the Console App Project targets .NET 4.0 Client Library.

While it might not have been related to this particular case, I think someone else can find this information useful.

Zip Arrays of same length:

Using Array.prototype.map()

const zip = (a, b) => a.map((k, i) => [k, b[i]]);

console.log(zip([1,2,3], ["a","b","c"]));
// [[1, "a"], [2, "b"], [3, "c"]]

Zip Arrays of different length:

Using Array.from()

const zip = (a, b) => Array.from(Array(Math.max(b.length, a.length)), (_, i) => [a[i], b[i]]);

console.log( zip([1,2,3], ["a","b","c","d"]) );
// [[1, "a"], [2, "b"], [3, "c"], [undefined, "d"]]

Using Array.prototype.fill() and Array.prototype.map()

const zip = (a, b) => Array(Math.max(b.length, a.length)).fill().map((_,i) => [a[i], b[i]]);

console.log(zip([1,2,3], ["a","b","c","d"]));
// [[1, "a"], [2, "b"], [3, "c"], [undefined, 'd']]

To blank it:

myObject["myVar"]=null;

To remove it:

delete myObject["myVar"]

I've been trying to activate 'active' class manually with javascript. It's not as usable as a complete library, but for easy cases seems to be enough:

var button = $('#myToggleButton');
button.on('click', function () {
  $(this).toggleClass('active');
});

If you think carefully, 'active' class is used by bootstrap when the button is being pressed, not before or after that (our case), so there's no conflict in reuse the same class.

Try this example and tell me if it fails: http://jsbin.com/oYoSALI/1/edit?html,js,output

You need to separate the arguments from the file path:

powershell.exe -noexit "& 'D:\Work\SQLExecutor.ps1 ' -gettedServerName 'MY-PC'"

Another option that may ease the syntax using the File parameter and positional parameters:

powershell.exe -noexit -file "D:\Work\SQLExecutor.ps1" "MY-PC"

There are lots of good reasons for setting the size of a frame. One is to remember the last size the user set, and restore those settings. I have this code which seems to work for me:

package javatools.swing;

    public static final String XPOS_PREF = "-xpos";

    public static final String YPOS_PREF = "-ypos";
    String prefix;
    Window frame;
    Class<?> cls;

    public FramePositionMemory(String prefix, Window frame, Class<?> cls) {
        this.prefix = prefix;
        this.frame = frame;
        this.cls = cls;
    }

    public void loadPosition() {
        Preferences prefs = (Preferences)Preferences.userNodeForPackage(cls);
    //  Restore the most recent mainframe size and location
        int width = prefs.getInt(prefix + WIDTH_PREF, frame.getWidth());
        int height = prefs.getInt(prefix + HEIGHT_PREF, frame.getHeight());
        System.out.println("WID: " + width + " HEI: " + height);
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        int xpos = (screenSize.width - width) / 2;
        int ypos = (screenSize.height - height) / 2;
        xpos = prefs.getInt(prefix + XPOS_PREF, xpos);
        ypos = prefs.getInt(prefix + YPOS_PREF, ypos);
        frame.setPreferredSize(new Dimension(width, height));
        frame.setLocation(xpos, ypos);
        frame.pack();
    }

    public void storePosition() {
        Preferences prefs = (Preferences)Preferences.userNodeForPackage(cls);
        prefs.putInt(prefix + WIDTH_PREF, frame.getWidth());
        prefs.putInt(prefix + HEIGHT_PREF, frame.getHeight());
        Point loc = frame.getLocation();

        final FramePositionMemory fm = new FramePositionMemory("scannacs2", frame, Main.class);
        frame.setSize(400, 400); // default size in the absence of previous setting
        fm.loadPosition();

        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        Runtime.getRuntime().addShutdownHook(new Thread() {
            @Override
            public void run() {
                fm.storePosition();
            }
        });
        frame.setVisible(true);
    }
}

}

I'd recomment using good old javascript:

document.getElementById("addRunner").reset();

Regarding 0xCC and 0xCD in particular, these are relics from the Intel 8088/8086 processor instruction set back in the 1980s. 0xCC is a special case of the software interrupt opcode INT 0xCD. The special single-byte version 0xCC allows a program to generate interrupt 3.

Although software interrupt numbers are, in principle, arbitrary, INT 3 was traditionally used for the debugger break or breakpoint function, a convention which remains to this day. Whenever a debugger is launched, it installs an interrupt handler for INT 3 such that when that opcode is executed the debugger will be triggered. Typically it will pause the currently running programming and show an interactive prompt.

Normally, the x86 INT opcode is two bytes: 0xCD followed by the desired interrupt number from 0-255. Now although you could issue 0xCD 0x03 for INT 3, Intel decided to add a special version--0xCC with no additional byte--because an opcode must be only one byte in order to function as a reliable 'fill byte' for unused memory.

The point here is to allow for graceful recovery if the processor mistakenly jumps into memory that does not contain any intended instructions. Multi-byte instructions aren't suited this purpose since an erroneous jump could land at any possible byte offset where it would have to continue with a properly formed instruction stream.

Obviously, one-byte opcodes work trivially for this, but there can also be quirky exceptions: for example, considering the fill sequence 0xCDCDCDCD (also mentioned on this page), we can see that it's fairly reliable since no matter where the instruction pointer lands (except perhaps the last filled byte), the CPU can resume executing a valid two-byte x86 instruction CD CD, in this case for generating software interrupt 205 (0xCD).

Weirder still, whereas CD CC CD CC is 100% interpretable--giving either INT 3 or INT 204--the sequence CC CD CC CD is less reliable, only 75% as shown, but generally 99.99% when repeated as an int-sized memory filler.

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

The error occurs when your repository does not have the default branch set for the remote. You can use the git remote set-head command to modify the default branch, and thus be able to use the remote name instead of a specified branch in that remote.

To query the remote (in this case origin) for its HEAD (typically master), and set that as the default branch:

$ git remote set-head origin --auto

If you want to use a different default remote branch locally, you can specify that branch:

$ git remote set-head origin new-default

Once the default branch is set, you can use just the remote name in git rebase <remote> and any other commands instead of explicit <remote>/<branch>.

Behind the scenes, this command updates the reference in .git/refs/remotes/origin/HEAD.

$ cat .git/refs/remotes/origin/HEAD 
ref: refs/remotes/origin/master

See the git-remote man page for further details.

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

lodash provides a shorthand method to check if undefined or null: _.isNil(yourVariable)

The case sensitivity of URLs, in general (along with whether they are same or not if they are in different case), needs to be looked at from the following perspectives:

• Resource Equivalence
• URL Comparison

From the perspective of resource equivalence it is generally not possible to say two URLs differing by any case (lower case, upper case, sentence case, camel case ... any combination of case) are different from each other unless the resource is retrieved from both the URLs, which in many cases is not practical (RFC 3986, section 6.1, para 1). Therefore where the resource cannot be retrieved, the comparison perspective is used.

However, in case where it is possible to retrieve the resource, the matter gets more (as expected) complicated. By the provisions of RFC 3986, Section 3.3, para 5, as highlighted below

Aside from dot-segments in hierarchical paths, a path segment is considered opaque by the generic syntax

it would appear that no assumption can be made for the rest of a URI/URL beyond it's scheme and authority from generic syntax (inclusive of the sensitivity question).

For scheme and host part of the authority, however, the specification does (charitably) state them to be case insensitive. Refer RFC 3986, section 3.1, para 1 and RFC 3986, section 6.2.2.1, para 2.

Having exhausted this line of inquiry one should look at the comparison perspective to determine whether URI/URLs are to be case sensitive or not.

The first hint to that direction emerges through perusal of the section 6.2.2.1 (above)

The other generic syntax components are assumed to be case-sensitive unless specifically defined otherwise by the scheme

Which is further buoyed by considering RFC 2616, section 3.2.3

When comparing two URIs to decide if they match or not, a client SHOULD use a case-sensitive octet-by-octet comparison of the entire URIs

Then, finally, is the enquiry settled and URLs are case sensitive ... (heh!), not quite, the operative words are 'opaque', 'client' and 'comparing'.

Beyond it's syntax, The above RFC don't mention anything about the actual interpretation of the path and query except that it is 'opaque' and it only specifies how (with a SHOULD and not a MUST) a 'client' may 'compare' the URL. It mentions nothing regarding how a server (SHOULD, let alone MUST) interpret the rest of the URL beyond scheme/authority.

Therefore the server has all the latitude to interpret an URL as they please, which they do as highlighted by earlier posts by others.

You could also, in another directory:

• git clone [your repository]
• Overwrite the .git directory in your original repository with the .git directory of the repository you just cloned right now.
• git add and git commit your original

You want the Except operator.

var answer = list1.Except(list2);

Better explanation here: https://docs.microsoft.com/archive/blogs/charlie/linq-farm-more-on-set-operators

NOTE: This technique works best for primitive types only, since you have to implement an IEqualityComparer to use the Except method with complex types.

you may use this:

Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False

In single line to print the element or array.

print $_ for (@array);

NOTE: remember that $_ is internally referring to the element of @array in loop. Any changes made in $_ will reflect in @array; ex.

my @array = qw( 1 2 3 );
for (@array) {
        $_ = $_ *2 ;
}
print "@array";

output: 2 4 6

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

I suggest this as a clean solution for US numbers.

public static string PhoneNumber(string value)
{ 
    if (string.IsNullOrEmpty(value)) return string.Empty;
    value = new System.Text.RegularExpressions.Regex(@"\D")
        .Replace(value, string.Empty);
    value = value.TrimStart('1');
    if (value.Length == 7)
        return Convert.ToInt64(value).ToString("###-####");
    if (value.Length == 10)
        return Convert.ToInt64(value).ToString("###-###-####");
    if (value.Length > 10)
        return Convert.ToInt64(value)
            .ToString("###-###-#### " + new String('#', (value.Length - 10)));
    return value;
}

I think the easiest trick is:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR API KEY&callback=initMap">google.maps.event.addDomListener(window,'load', initMap);</script>

It will init the map when your app is ready.

Check this.

Push annotated tags, keep lightweight local

man git-tag says:

Annotated tags are meant for release while lightweight tags are meant for private or temporary object labels.

And certain behaviors do differentiate between them in ways that this recommendation is useful e.g.:

• annotated tags can contain a message, creator, and date different than the commit they point to. So you could use them to describe a release without making a release commit.

  Lightweight tags don't have that extra information, and don't need it, since you are only going to use it yourself to develop.

• git push --follow-tags will only push annotated tags
• git describe without command line options only sees annotated tags

Internals differences

• both lightweight and annotated tags are a file under .git/refs/tags that contains a SHA-1

• for lightweight tags, the SHA-1 points directly to a commit:

  git tag light
  cat .git/refs/tags/light
  

  prints the same as the HEAD's SHA-1.

  So no wonder they cannot contain any other metadata.

• annotated tags point to a tag object in the object database.

  git tag -as -m msg annot
  cat .git/refs/tags/annot
  

  contains the SHA of the annotated tag object:

  c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  and then we can get its content with:

  git cat-file -p c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  sample output:

  object 4284c41353e51a07e4ed4192ad2e9eaada9c059f
  type commit
  tag annot
  tagger Ciro Santilli <[email protected]> 1411478848 +0200
  
  msg
  -----BEGIN PGP SIGNATURE-----
  Version: GnuPG v1.4.11 (GNU/Linux)
  
  <YOUR PGP SIGNATURE>
  -----END PGP SIGNAT
  

  And this is how it contains extra metadata. As we can see from the output, the metadata fields are:

  • the object it points to
  • the type of object it points to. Yes, tag objects can point to any other type of object like blobs, not just commits.
  • the name of the tag
  • tagger identity and timestamp
  • message. Note how the PGP signature is just appended to the message

  A more detailed analysis of the format is present at: What is the format of a git tag object and how to calculate its SHA?

Bonuses

• Determine if a tag is annotated:

  git cat-file -t tag
  

  Outputs

  • commit for lightweight, since there is no tag object, it points directly to the commit
  • tag for annotated, since there is a tag object in that case

• List only lightweight tags: How can I list all lightweight tags?

First Create Procedure as Below:

CREATE DEFINER=`root`@`%` PROCEDURE `sp_split`(str nvarchar(6500), dilimiter varchar(15), tmp_name varchar(50))
BEGIN

    declare end_index   int;
    declare part        nvarchar(6500);
    declare remain_len  int;

    set end_index      = INSTR(str, dilimiter);

    while(end_index   != 0) do

        /* Split a part */
        set part       = SUBSTRING(str, 1, end_index - 1);

        /* insert record to temp table */
        call `sp_split_insert`(tmp_name, part);

        set remain_len = length(str) - end_index;
        set str = substring(str, end_index + 1, remain_len);

        set end_index  = INSTR(str, dilimiter);

    end while;

    if(length(str) > 0) then

        /* insert record to temp table */
        call `sp_split_insert`(tmp_name, str);

    end if;

END

After that create procedure as below:

CREATE DEFINER=`root`@`%` PROCEDURE `sp_split_insert`(tb_name varchar(255), tb_value nvarchar(6500))
BEGIN
    SET @sql = CONCAT('Insert Into ', tb_name,'(item) Values(?)'); 
    PREPARE s1 from @sql;
    SET @paramA = tb_value;
    EXECUTE s1 USING @paramA;
END

How call test

CREATE DEFINER=`root`@`%` PROCEDURE `test_split`(test_text nvarchar(255))
BEGIN

    create temporary table if not exists tb_search
        (
            item nvarchar(6500)
        );

    call sp_split(test_split, ',', 'tb_search');

    select * from tb_search where length(trim(item)) > 0;

    drop table tb_search;

END


call `test_split`('Apple,Banana,Mengo');

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

From: http://technet.microsoft.com/en-us/library/ee681792.aspx:

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

No CSS required, visible class should like this: visible-md-block not just visible-md and the code should be like this:

<div class="containerdiv hidden-sm hidden-xs visible-md-block visible-lg-block">
    <div class="row">
        <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4 logo">

        </div>
    </div>
</div>

<div class="mobile hidden-md hidden-lg ">
    test
</div>

Extra css is not required at all.

You do cast, because:

• It makes your code more portable between C and C++, and as SO experience shows, a great many programmers claim they are writing in C when they are really writing in C++ (or C plus local compiler extensions).
• Failing to do so can hide an error: note all the SO examples of confusing when to write type * versus type **.
• The idea that it keeps you from noticing you failed to #include an appropriate header file misses the forest for the trees. It's the same as saying "don't worry about the fact you failed to ask the compiler to complain about not seeing prototypes -- that pesky stdlib.h is the REAL important thing to remember!"
• It forces an extra cognitive cross-check. It puts the (alleged) desired type right next to the arithmetic you're doing for the raw size of that variable. I bet you could do an SO study that shows that malloc() bugs are caught much faster when there's a cast. As with assertions, annotations that reveal intent decrease bugs.
• Repeating yourself in a way that the machine can check is often a great idea. In fact, that's what an assertion is, and this use of cast is an assertion. Assertions are still the most general technique we have for getting code correct, since Turing came up with the idea so many years ago.

function isValidDate(year, month, day) {
        var d = new Date(year, month - 1, day, 0, 0, 0, 0);
        return (!isNaN(d) && (d.getDate() == day && d.getMonth() + 1 == month && d.getYear() == year));
    }

If you just want a list:

ArrayList<Class> myList = new ArrayList<Class>();

If you want an arraylist of a certain length (in this case size 10):

List<Class> myList = new ArrayList<Class>(10);

If you want to program against the interfaces (better for abstractions reasons):

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

Programming against interfaces is considered better because it's more abstract. You can change your Arraylist with a different list implementation (like a LinkedList) and the rest of your application doesn't need any changes.

To answer your question - nginx picks the first server if there's no match. See documentation:

If its value does not match any server name, or the request does not contain this header field at all, then nginx will route the request to the default server for this port. In the configuration above, the default server is the first one...

Now, if you wanted to have a default catch-all server that, say, responds with 404 to all requests, then here's how to do it:

server {
    listen 80 default_server;
    listen 443 ssl default_server;
    server_name _;
    ssl_certificate <path to cert>
    ssl_certificate_key <path to key>
    return 404;
}

Note that you need to specify certificate/key (that can be self-signed), otherwise all SSL connections will fail as nginx will try to accept connection using this default_server and won't find cert/key.

On Python = 3.5, use pathlib.Path.mkdir:

from pathlib import Path
Path("/my/directory").mkdir(parents=True, exist_ok=True)

For older versions of Python, I see two answers with good qualities, each with a small flaw, so I will give my take on it:

Try os.path.exists, and consider os.makedirs for the creation.

import os
if not os.path.exists(directory):
    os.makedirs(directory)

As noted in comments and elsewhere, there's a race condition – if the directory is created between the os.path.exists and the os.makedirs calls, the os.makedirs will fail with an OSError. Unfortunately, blanket-catching OSError and continuing is not foolproof, as it will ignore a failure to create the directory due to other factors, such as insufficient permissions, full disk, etc.

One option would be to trap the OSError and examine the embedded error code (see Is there a cross-platform way of getting information from Python’s OSError):

import os, errno

try:
    os.makedirs(directory)
except OSError as e:
    if e.errno != errno.EEXIST:
        raise

Alternatively, there could be a second os.path.exists, but suppose another created the directory after the first check, then removed it before the second one – we could still be fooled.

Depending on the application, the danger of concurrent operations may be more or less than the danger posed by other factors such as file permissions. The developer would have to know more about the particular application being developed and its expected environment before choosing an implementation.

Modern versions of Python improve this code quite a bit, both by exposing FileExistsError (in 3.3+)...

try:
    os.makedirs("path/to/directory")
except FileExistsError:
    # directory already exists
    pass

...and by allowing a keyword argument to os.makedirs called exist_ok (in 3.2+).

os.makedirs("path/to/directory", exist_ok=True)  # succeeds even if directory exists.

Run:

$ git rebase --interactive commit_hash^

each ^ indicates how many commits back you want to edit, if it's only one (the commit hash that you specified), then you just add one ^.

Using Vim you change the words pick to reword for the commits you want to change, save and quit(:wq). Then git will prompt you with each commit that you marked as reword so you can change the commit message.

Each commit message you have to save and quit(:wq) to go to the next commit message

If you want to exit without applying the changes, press :q!

EDIT: to navigate in vim you use j to go up, k to go down, h to go left, and l to go right( all this in NORMAL mode, press ESC to go to NORMAL mode ). To edit a text, press i so that you enter the INSERT mode, where you insert text. Press ESC to go back to NORMAL mode :)

UPDATE: Here's a great link from github listing How to undo (almost) anything with git

workmad3 is apparently out of date, at least for current gpg, as the --allow-secret-key-import is now obsolete and does nothing.

What happened to me was that I failed to export properly. Just doing gpg --export is not adequate, as it only exports the public keys. When exporting keys, you have to do

gpg --export-secret-keys >keyfile

Assuming no key contains either ',' or ':':

Map<String, Integer> map = new HashMap<String, Integer>();
for(final String entry : s.split(",")) {
    final String[] parts = entry.split(":");
    assert(parts.length == 2) : "Invalid entry: " + entry;
    map.put(parts[0], new Integer(parts[1]));
}

We had the same issue with our ClickOnce application that uses Interop with Microsoft Office. It happened only on a few computers in the company.

The best fix we found out was to modify MS Office installation on problematic computers (through the Programs and Features panel) and ensure that ".NET programmability feature" (not sure of the name of the component - our Microsoft_Office versions are not English) was installed for each of the MS Office applications (Excel, Word, Outlook, etc.). This seems to not be included in a default install.

Then the problem with stdole.dll was fixed.

I hope this might help.

VALUES ('"+user+"' , '"+FirstTest+"'  , '"+LastTest+"'..............etc)

You can use it to insert variables into sql query.

thisTag = _tags.FirstOrDefault(t => t.Key == tag);

is an inefficient and a little bit strange way to find something by key in a dictionary. Looking things up for a Key is the basic function of a Dictionary.

The basic solution would be:

if (_tags.Containskey(tag)) { string myValue = _tags[tag]; ... }

But that requires 2 lookups.

TryGetValue(key, out value) is more concise and efficient, it only does 1 lookup. And that answers the last part of your question, the best way to do a lookup is:

string myValue;
if (_tags.TryGetValue(tag, out myValue)) { /* use myValue */ }

VS 2017 update, for C# 7 and beyond we can declare the result variable inline:

if (_tags.TryGetValue(tag, out string myValue))
{
    // use myValue;
}
// use myValue, still in scope, null if not found

One can also use the following syntax in typescript. Note the backtick " ` "

window.location.hash = `${page_number}`

Another characteristic of Prepared or Parameterized Query: Reference taken from this article.

This statement is one of features of the database system in which same SQL statement executes repeatedly with high efficiency. The prepared statements are one kind of the Template and used by application with different parameters.

The statement template is prepared and sent to the database system and database system perform parsing, compiling and optimization on this template and store without executing it.

Some of parameter like, where clause is not passed during template creation later application, send these parameters to the database system and database system use template of SQL Statement and executes as per request.

Prepared statements are very useful against SQL Injection because the application can prepare parameter using different techniques and protocols.

When the number of data is increasing and indexes are changing frequently at that time Prepared Statements might be fail because in this situation require a new query plan.

Avoid PID-files, crons, or anything else that tries to evaluate processes that aren't their children.

There is a very good reason why in UNIX, you can ONLY wait on your children. Any method (ps parsing, pgrep, storing a PID, ...) that tries to work around that is flawed and has gaping holes in it. Just say no.

Instead you need the process that monitors your process to be the process' parent. What does this mean? It means only the process that starts your process can reliably wait for it to end. In bash, this is absolutely trivial.

until myserver; do
    echo "Server 'myserver' crashed with exit code $?.  Respawning.." >&2
    sleep 1
done

The above piece of bash code runs myserver in an until loop. The first line starts myserver and waits for it to end. When it ends, until checks its exit status. If the exit status is 0, it means it ended gracefully (which means you asked it to shut down somehow, and it did so successfully). In that case we don't want to restart it (we just asked it to shut down!). If the exit status is not 0, until will run the loop body, which emits an error message on STDERR and restarts the loop (back to line 1) after 1 second.

Why do we wait a second? Because if something's wrong with the startup sequence of myserver and it crashes immediately, you'll have a very intensive loop of constant restarting and crashing on your hands. The sleep 1 takes away the strain from that.

Now all you need to do is start this bash script (asynchronously, probably), and it will monitor myserver and restart it as necessary. If you want to start the monitor on boot (making the server "survive" reboots), you can schedule it in your user's cron(1) with an @reboot rule. Open your cron rules with crontab:

crontab -e

Then add a rule to start your monitor script:

@reboot /usr/local/bin/myservermonitor

Alternatively; look at inittab(5) and /etc/inittab. You can add a line in there to have myserver start at a certain init level and be respawned automatically.

Edit.

Let me add some information on why not to use PID files. While they are very popular; they are also very flawed and there's no reason why you wouldn't just do it the correct way.

Consider this:

1. PID recycling (killing the wrong process):

   • /etc/init.d/foo start: start foo, write foo's PID to /var/run/foo.pid
   • A while later: foo dies somehow.
   • A while later: any random process that starts (call it bar) takes a random PID, imagine it taking foo's old PID.
   • You notice foo's gone: /etc/init.d/foo/restart reads /var/run/foo.pid, checks to see if it's still alive, finds bar, thinks it's foo, kills it, starts a new foo.

2. PID files go stale. You need over-complicated (or should I say, non-trivial) logic to check whether the PID file is stale, and any such logic is again vulnerable to 1..

3. What if you don't even have write access or are in a read-only environment?

4. It's pointless overcomplication; see how simple my example above is. No need to complicate that, at all.

See also: Are PID-files still flawed when doing it 'right'?

By the way; even worse than PID files is parsing ps! Don't ever do this.

1. ps is very unportable. While you find it on almost every UNIX system; its arguments vary greatly if you want non-standard output. And standard output is ONLY for human consumption, not for scripted parsing!
2. Parsing ps leads to a LOT of false positives. Take the ps aux | grep PID example, and now imagine someone starting a process with a number somewhere as argument that happens to be the same as the PID you stared your daemon with! Imagine two people starting an X session and you grepping for X to kill yours. It's just all kinds of bad.

If you don't want to manage the process yourself; there are some perfectly good systems out there that will act as monitor for your processes. Look into runit, for example.

git reset --hard a
git reset --mixed d
git commit

That will act as a revert for all of them at once. Give a good commit message.

I experienced this today. The value in Config was the updated one but the application would return the older value, stop and starting the solution did nothing.

So I cleared the .Net Temp folder.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

It shouldn't create bugs but to be safe close your solution down first. Clear the Temporary ASP.NET Files then load up your solution.

My issue was sorted.

I remember JavaScript Closures when I See this.. Here is how i do it..

        function Increment() {
            var num = 0; // Here num is a private static variable
            return function () {
                return ++num;
            }
        }

        var inc = new Increment();
        console.log(inc());//Prints 1
        console.log(inc());//Prints 2
        console.log(inc());//Prints 3

If you have names of the element and not id we can achieve the undefined check on all text elements (for example) as below and fill them with a default value say 0.0:

var aFieldsCannotBeNull=['ast_chkacc_bwr','ast_savacc_bwr'];
 jQuery.each(aFieldsCannotBeNull,function(nShowIndex,sShowKey) {
   var $_oField = jQuery("input[name='"+sShowKey+"']");
   if($_oField.val().trim().length === 0){
       $_oField.val('0.0')
    }
  })

You have to use absolute path in this case. But if you set the CopyToOutputDirectory = CopyAlways, it will work as you are doing it.

I think Adam was asking how to change umask value for all processes that tying to operate on /opt/lampp/htdocs directory.

The user file-creation mode mask (umask) is use to determine the file permission for newly created files. It can be used to control the default file permission for new files.

so if you will use some kind of ftp program to upload files into /opt/lampp/htdocs you need to configure your ftp server to use umask you want.

If files / directories be created for example by php, you need to modify php code

<?php
umask(0022);
// other code
?>

if you will create new files / folders from your bash session, you can set umask value in your shell profile ~/.bashrc Or you can set up umask in /etc/bashrc or /etc/profile file for all users. add the following to file: umask 022

Sample umask Values and File Creation Permissions
If umask value set to   User permission     Group permission     Others permission
000                         all              all                   all
007                         all              all                   none
027                         all          read / execute            none

And to change permissions for already created files you can use find. Hope this helps.

why don't you store your values in HTML5 storage objects such as sessionStorage or localStorage, visit HTML5 Storage Doc to get more details. Using this you can store intermediate values temporarily/permanently locally and then access your values later.

To store values for a session:

sessionStorage.getItem('label')
sessionStorage.setItem('label', 'value')

or more permanently:

localStorage.getItem('label')
localStorage.setItem('label', 'value')

So you can store (temporarily) form data between multiple pages using HTML5 storage objects which you can even retain after reload..

What regex engine are you using? Most of them will support the following expression:

\{\d+:\d+\}

The \d is actually shorthand for [0-9], but the important part is the addition of + which means "one or more".

A quick solution that might help someone :

Add this line as value for start ng serve --host 0.0.0.0 --disable-host-check in your package.json

ex:

{
"ng": "ng",
"start": "ng serve --host 0.0.0.0 --disable-host-check",
"build": "ng build",
}

And then simply do start or npm run start

you will be able to access your project from other local IPs.

I had the same error. I checked the error logs: C:\ProgramData\MySQL\MySQL Server 5.5\data\inf3rno-PC.err. According to them

I think the important part here

170208  1:10:44  InnoDB: Error: unable to create temporary file; errno: 2

I changed the TMP and TEMP env variables from C:\Windows\Temp to %USERPROFILE%\AppData\Local\Temp yesterday, because I was unable to compress a directory and according to many post the solution is that. Now compression works, but mysql and apparently nod32 complains that they cannot create temporary files...

I added tmpdir=c:/server/mytmp to C:\Program Files\MySQL\MySQL Server 5.5\my.ini. And after that started the service again with services.msc. It is okay now.

So this can be a possible cause as well. I strongly suggest to everybody encountering this problem to check the error logs.

Try this:

$('input:radio[name="mygroup"][value="5"]').attr('checked',true);

JS Fiddle demo.

Correct answer is simply:

SELECT a.group_id
FROM a 
LEFT JOIN b ON a.group_id=b.group_id  and b.user_id = 4
where b.user_id is null
  and a.keyword like '%keyword%'

Here we are checking user_id = 4 (your user id from the session). Since we have it in the join criteria, it will return null values for any row in table b that does not match the criteria - ie, any group that that user_id is NOT in.

From there, all we need to do is filter for the null values, and we have all the groups that your user is not in.

:: is the scope resolution operator. It's used to specify the scope of something.

For example, :: alone is the global scope, outside all other namespaces.

some::thing can be interpreted in any of the following ways:

• some is a namespace (in the global scope, or an outer scope than the current one) and thing is a type, a function, an object or a nested namespace;
• some is a class available in the current scope and thing is a member object, function or type of the some class;
• in a class member function, some can be a base type of the current type (or the current type itself) and thing is then one member of this class, a type, function or object.

You can also have nested scope, as in some::thing::bad. Here each name could be a type, an object or a namespace. In addition, the last one, bad, could also be a function. The others could not, since functions can't expose anything within their internal scope.

So, back to your example, ::thing can be only something in the global scope: a type, a function, an object or a namespace.

The way you use it suggests (used in a pointer declaration) that it's a type in the global scope.

I hope this answer is complete and correct enough to help you understand scope resolution.

The table is only dropped and re-created in cases where that's the only way SQL Server's Management Studio has been programmed to know how to do it.

There are certainly cases where it will do that when it doesn't need to, but there will also be cases where edits you make in Management Studio will not drop and re-create because it doesn't have to.

The problem is that enumerating all of the cases and determining which side of the line they fall on will be quite tedious.

This is why I like to use ALTER TABLE in a query window, instead of visual designers that hide what they're doing (and quite frankly have bugs) - I know exactly what is going to happen, and I can prepare for cases where the only possibility is to drop and re-create the table (which is some number less than how often SSMS will do that to you).

The methods offered here are faulty.

            return nil
        }
        debugPrint("Image file size after compression: \(compressedImageData.count) bytes")

        do {
            try compressedImageData.write(to: compressedURL)
            return compressedURL
        } catch {
            return nil
        }
    }
}

Usage:

guard let localImageURL = URL(string: "< LocalImagePath.jpg >") else {
    return
}

//Here you will get URL of compressed image
guard let compressedImageURL = try localImageURL.compressedImageURL() else {
    return
}

debugPrint("compressedImageURL: \(compressedImageURL.absoluteString)")

Note:- Change < LocalImagePath.jpg > with your local jpg image path.

This might work for you (GNU sed):

sed -r '1{x;s/^/:abbc:bcab/;x};G;s/^/\n/;:a;/\n\n/{P;d};s/\n(ab|bc)(.*\n.*:(\1)([^:]*))/\4\n\2/;ta;s/\n(.)/\1\n/;ta' file

This uses a lookup table which is prepared and held in the hold space (HS) and then appended to each line. An unique marker (in this case \n) is prepended to the start of the line and used as a method to bump-along the search throughout the length of the line. Once the marker reaches the end of the line the process is finished and is printed out the lookup table and markers being discarded.

N.B. The lookup table is prepped at the very start and a second unique marker (in this case :) chosen so as not to clash with the substitution strings.

With some comments:

sed -r '
  # initialize hold with :abbc:bcab
  1 {
    x
    s/^/:abbc:bcab/
    x
  }

  G        # append hold to patt (after a \n)

  s/^/\n/  # prepend a \n

  :a

  /\n\n/ {
    P      # print patt up to first \n
    d      # delete patt & start next cycle
  }

  s/\n(ab|bc)(.*\n.*:(\1)([^:]*))/\4\n\2/
  ta       # goto a if sub occurred

  s/\n(.)/\1\n/  # move one char past the first \n
  ta       # goto a if sub occurred
'

The table works like this:

   **   **   replacement
:abbc:bcab
 **   **     pattern

pip install django-cors-headers

and then add it to your installed apps:

INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

You will also need to add a middleware class to listen in on responses:

MIDDLEWARE_CLASSES = (
    ...
    'corsheaders.middleware.CorsMiddleware',  
    'django.middleware.common.CommonMiddleware',  
    ...
)

CORS_ORIGIN_ALLOW_ALL = True # If this is used then `CORS_ORIGIN_WHITELIST` will not have any effect
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_WHITELIST = [
    'http://localhost:3030',
] # If this is used, then not need to use `CORS_ORIGIN_ALLOW_ALL = True`
CORS_ORIGIN_REGEX_WHITELIST = [
    'http://localhost:3030',
]

All Perl's "special variables" are listed in the perlvar documentation page.

I'm currently in the process of migrating from SVN to a DVCS (while blogging about my findings, my first real blogging effort...), and I've done a bit of research (=googling). As far as I can see you can do most of the things with both packages. It seems like git has a few more or better implemented advanced features, I do feel that the integration with windows is a bit better for mercurial, with TortoiseHg. I know there's Git Cheetah as well (I tried both), but the mercurial solution just feels more robust.

Seeing how they're both open-source (right?) I don't think either will be lacking important features. If something is important, people will ask for it, people will code it.

I think that for common practices, Git and Mercurial are more than sufficient. They both have big projects that use them (Git -> linux kernel, Mercurial -> Mozilla foundation projects, both among others of course), so I don't think either are really lacking something.

That being said, I am interested in what other people say about this, as it would make a great source for my blogging efforts ;-)

I'm not absolutely sure I got your question correctly, but it seems you want something like this:

    Class c = null;
    try {
        c = Class.forName("com.path.to.ImplementationType");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    T interfaceType = null;
    try {
        interfaceType = (T) c.newInstance();
    } catch (InstantiationException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }

Where T can be defined in method level or in class level, i.e. <T extends InterfaceType>

A cleaner way to do this:

class Book {
    public Title: string;
    public Price: number;
    public Description: string;

    constructor(public BookId: number, public Author: string){}
}

Then

var bks: Book[] = [
    new Book(1, "vamsee")
];

use return for this

if(i==1) { 
    return; //stop the execution of function
}

//keep on going

I had a similar situation. On top of what you did, I wanted to center my columns in the container while not allowing empty columns to for them left or right:

.grid { 
    display: grid;
    grid-gap: 10px;
    justify-content: center;
    grid-template-columns: repeat(auto-fit, minmax(200px, auto));
}

Here is another way of doing it, similar to Dan Allan's answer but without the lambda function:

>>> pd.options.display.float_format = '{:.2f}'.format
>>> Series(np.random.randn(3))
0    0.41
1    0.99
2    0.10

or

>>> pd.set_option('display.float_format', '{:.2f}'.format)

In order to start a service in its own process, you must specify the following in the xml declaration.

<service
  android:name="WordService"
  android:process=":my_process" 
  android:icon="@drawable/icon"
  android:label="@string/service_name"
  >
</service>

enter code here

import numpy as np

clrs = np.linspace( 0, 1, 18 )  # It will generate 
# color only for 18 for more change the number
np.random.shuffle(clrs)
colors = []
for i in range(0, 72, 4):
    idx = np.arange( 0, 18, 1 )
    np.random.shuffle(idx)
    r = clrs[idx[0]]
    g = clrs[idx[1]]
    b = clrs[idx[2]]
    a = clrs[idx[3]]
    colors.append([r, g, b, a])

Few characters like alphabets i-o couldn't be converted into respective ASCII chars . like in string '6631653064316f30723161' corresponds to fedora . but it gives fedra

Just modify hex_to_int() function a little and it will work for all characters. modified function is

int hex_to_int(char c)
{
    if (c >= 97)
        c = c - 32;
    int first = c / 16 - 3;
    int second = c % 16;
    int result = first * 10 + second;
    if (result > 9) result--;
    return result;
}

Now try it will work for all characters.

There's also SSH Key - Still asking for password and passphrase

Using ssh-add ~/.ssh/id_rsa without a local keychain.

This avoids having to mess with tokens.

Given supercat's comments, the tendencies of modern compilers, and other things, I'd be tempted to go back to the ancient days and write the whole code in assembly and static memory allocations everywhere. For this kind of utter reliability I think assembly no longer incurs a large percentage difference of the cost.

Usage: If you're going to store information that you want to access on different web pages, you can use SessionState

If you want to store information that you want to access from the same page, then you can use Viewstate

Storage The Viewstate is stored within the page itself (in encrypted text), while the Sessionstate is stored in the server.

The SessionState will clear in the following conditions

1. Cleared by programmer
2. Cleared by user
3. Timeout

For this you have to use HtmlAttributes, but there is a catch: HtmlAttributes and css class .

you can define it like this:

new { Attrubute="Value", AttributeTwo = IntegerValue, @class="className" };

and here is a more realistic example:

new { style="width:50px" };
new { style="width:50px", maxsize = 50 };
new {size=30, @class="required"}

and finally in:

MVC 1

<%= Html.TextBox("test", new { style="width:50px" }) %> 

MVC 2

<%= Html.TextBox("test", null, new { style="width:50px" }) %> 

MVC 3

@Html.TextBox("test", null, new { style="width:50px" })

If by application id, you're referring to package name, you can use the method Context::getPackageName (http://http://developer.android.com/reference/android/content/Context.html#getPackageName%28%29).

In case you wish to communicate with other application, there are multiple ways:

1. Start an activity of another application and send data in the "Extras" of the "Intent"
2. Send a broadcast with specific action/category and send data in the extras
3. If you just need to share structured data, use content provider
4. If the other application needs to continuously run in the background, use Server and "bind" yourself to the service.

If you can elaborate your exact requirement, the community will be able to help you better.

I know it's been said already, but I'd highly recommend the requests Python package.

If you've used languages other than python, you're probably thinking urllib and urllib2 are easy to use, not much code, and highly capable, that's how I used to think. But the requests package is so unbelievably useful and short that everyone should be using it.

First, it supports a fully restful API, and is as easy as:

import requests

resp = requests.get('http://www.mywebsite.com/user')
resp = requests.post('http://www.mywebsite.com/user')
resp = requests.put('http://www.mywebsite.com/user/put')
resp = requests.delete('http://www.mywebsite.com/user/delete')

Regardless of whether GET / POST, you never have to encode parameters again, it simply takes a dictionary as an argument and is good to go:

userdata = {"firstname": "John", "lastname": "Doe", "password": "jdoe123"}
resp = requests.post('http://www.mywebsite.com/user', data=userdata)

Plus it even has a built in JSON decoder (again, I know json.loads() isn't a lot more to write, but this sure is convenient):

resp.json()

Or if your response data is just text, use:

resp.text

This is just the tip of the iceberg. This is the list of features from the requests site:

• International Domains and URLs
• Keep-Alive & Connection Pooling
• Sessions with Cookie Persistence
• Browser-style SSL Verification
• Basic/Digest Authentication
• Elegant Key/Value Cookies
• Automatic Decompression
• Unicode Response Bodies
• Multipart File Uploads
• Connection Timeouts
• .netrc support
• List item
• Python 2.6—3.4
• Thread-safe.

The complete solution I found that worked was:

@echo off
cd /D "%~dp0"
if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b)
"Put your command here"

I think you want NUL, at least within a command prompt or batch files.

For example:

type c:\autoexec.bat > NUL

doesn't create a file.

(I believe the same is true if you try to create a file programmatically, but I haven't tried it.)

In PowerShell, you want $null:

echo 1 > $null

You're not actually using promises here. Parse lets you use callbacks or promises; your choice.

To use promises, do the following:

query.find().then(function() {
    console.log("success!");
}, function() {
    console.log("error");
});

Now, to execute stuff after the promise is complete, you can just execute it inside the promise callback inside the then() call. So far this would be exactly the same as regular callbacks.

To actually make good use of promises is when you chain them, like this:

query.find().then(function() {
    console.log("success!");

    return new Parse.Query(Obj).get("sOmE_oBjEcT");
}, function() {
    console.log("error");
}).then(function() {
    console.log("success on second callback!");
}, function() {
    console.log("error on second callback");
});

What you have should work but can be reduced to:

select * from table where concat_ws(' ',first_name,last_name) 
like '%$search_term%';

Can you provide an example name and search term where this doesn't work?

Here's a ES6 using Await / Async example:

    async deleteProduct(id) {

        if (!id) {
            return {msg: 'No Id specified..', payload: 1};
        }

        try {
            return !!await products.destroy({
                where: {
                    id: id
                }
            });
        } catch (e) {
            return false;
        }

    }

Please note that I'm using the !! Bang Bang Operator on the result of the await which will change the result into a Boolean.

if you did change the httpd.conf file located under conf_files folder, don't use windows notepad, you need a unix text editor, try TED pad, after making any changes to your httpd.conf file save it. ps: if you use a dos/windows editor you will end up with an "Error in Apache file changed" message. so do be careful....

The accepted answer didn't seem to solve the problem for me, but this did

Ensure your backgroundImage declarations are wrapped in url( and quotes so the style works correctly, no matter the file name.

ES2015 Style:

<div :style="{ backgroundImage: `url('${image}')` }"></div>

Or without ES2015:

<div :style="{ backgroundImage: 'url(\'' + image + '\')' }"></div>

I also posted an answer to a related question here.

I had a similar problem, here's my solution:

1. Right click on your project and select Properties.
2. Select Java Build Path from the menu on the left.
3. Select the Order and Export tab.
4. From the list make sure the libraries or external jars you added to your project are checked.
5. Finally, clean your project & run.

Following query is useful and simple-

declare @floatExchRate float;
set @floatExchRate=(select convert(decimal(10, 2), 0.2548712))
select  @floatExchRate

Gives output as 0.25.

You can create your own custom auth schemas that use the Authorization: header - for example, this is how OAuth works.

As a general rule, if servers or proxies don't understand the values of standard headers, they will leave them alone and ignore them. It is creating your own header keys that can often produce unexpected results - many proxies will strip headers with names they don't recognise.

Having said that, it is possibly a better idea to use cookies to transmit the token, rather than the Authorization: header, for the simple reason that cookies were explicitly designed to carry custom values, whereas the specification for HTTP's built in auth methods does not really say either way - if you want to see exactly what it does say, have a look here.

The other point about this is that many HTTP client libraries have built-in support for Digest and Basic auth but may make life more difficult when trying to set a raw value in the header field, whereas they will all provide easy support for cookies and will allow more or less any value within them.

Here's what I use:

<logger name="org.hibernate">
    <level value="warn"/>
</logger>

<logger name="org.hibernate.SQL">
    <level value="warn"/>
</logger>

<logger name="org.hibernate.type">
    <level value="warn"/>
</logger>

<root>
    <priority value="info"/>
    <appender-ref ref="C1"/>
</root> 

Obviously, I don't like to see Hibernate messages ;) -- set the level to "debug" to get the output.

I have solved this issue,

login to server computer where SQL Server is installed get you csv file on server computer and execute your query it will insert the records.

If you will give datatype compatibility issue change the datatype for that column

You can do this using generic.

public class BaseClass
{
    public int A { get; set; }
    public int B { get; set; }
    private T ConvertTo<T>() where T : BaseClass, new()
    {
         return new T
         {
             A = A,
             B = B
         }
    }

    public DerivedClass1 ConvertToDerivedClass1()
    {
         return ConvertTo<DerivedClass1>();
    }

    public DerivedClass2 ConvertToDerivedClass2()
    {
         return ConvertTo<DerivedClass2>();
    }
}

public class DerivedClass1 : BaseClass
{
    public int C { get; set; }
}

public class DerivedClass2 : BaseClass
{
    public int D { get; set; }
}

You get three benefits using this approach.

1. You are not duplicating the code
2. You are not using reflection (which is slow)
3. All of your conversions are in one place

You can setup _JAVA_OPTIONS instead of JAVA_OPTS. This should work without $_JAVA_OPTIONS.

Form 1 - #include < xxx >

First, looks for the presence of header file in the current directory from where directive is invoked. If not found, then it searches in the preconfigured list of standard system directories.

Form 2 - #include "xxx"

This looks for the presence of header file in the current directory from where directive is invoked.

The exact search directory list depends on the target system, how GCC is configured, and where it is installed. You can find the search directory list of your GCC compiler by running it with -v option.

You can add additional directories to the search path by using - Idir, which causes dir to be searched after the current directory (for the quote form of the directive) and ahead of the standard system directories.

Basically, the form "xxx" is nothing but search in current directory; if not found falling back the form

Just like the others said before the way to do this is to press ctrl+w and then o. This will "maximize" the current window, while closing the others. If you'd like to be able to "unmaximize" it, there's a plugin called ZoomWin for that. Otherwise you'd have to recreate the window setup from scratch.

Refreshing db context with Reload is not recommended way due to performance loses. It is good enough and the best practice to initialize a new instance of the dbcontext before each operation executed. It also provide you a refreshed up to date context for each operation.

using (YourContext ctx = new YourContext())
{
   //Your operations
}

Use a T-SQL IF:

java.lang.Integer is not a super class of BigInteger. Both BigInteger and Integer do inherit from java.lang.Number, so you could cast to a java.lang.Number.

See the java docs http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Number.html

I am looking for a way to create a select without repeating the conditional query.

I'm assuming that you don't want to repeat Foo-stuff+bar. You could put your calculation into a derived table:

SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END 
FROM (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable) AS a

A common table expression would work just as well:

WITH a AS (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable)
SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END    
FROM a

Also, each part of your switch should return the same datatype, so you may have to cast one or more cases.

by typing yes it wont charge taxes, by typing no it will charge taxes.

=IF(C39="Yes","0",IF(C39="no",PRODUCT(G36*0.0825)))

This will add a path to your Python process / instance (i.e. the running executable). The path will not be modified for any other Python processes. Another running Python program will not have its path modified, and if you exit your program and run again the path will not include what you added before. What are you are doing is generally correct.

set.py:

import sys
sys.path.append("/tmp/TEST")

loop.py

import sys
import time
while True:
  print sys.path
  time.sleep(1)

run: python loop.py &

This will run loop.py, connected to your STDOUT, and it will continue to run in the background. You can then run python set.py. Each has a different set of environment variables. Observe that the output from loop.py does not change because set.py does not change loop.py's environment.

A note on importing

Python imports are dynamic, like the rest of the language. There is no static linking going on. The import is an executable line, just like sys.path.append....

Not sure if I get you right, but the simplest way would be something like:

<c:if test="${languageBean.locale == 'en'">
  <f:selectItems value="#{customerBean.selectableCommands_limited_en}" />
</c:if>

Just a quick copy and paste from an app of mine...

Differences

• KEY or INDEX refers to a normal non-unique index. Non-distinct values for the index are allowed, so the index may contain rows with identical values in all columns of the index. These indexes don't enforce any restraints on your data so they are used only for access - for quickly reaching certain ranges of records without scanning all records.

• UNIQUE refers to an index where all rows of the index must be unique. That is, the same row may not have identical non-NULL values for all columns in this index as another row. As well as being used to quickly reach certain record ranges, UNIQUE indexes can be used to enforce restraints on data, because the database system does not allow the distinct values rule to be broken when inserting or updating data.

  Your database system may allow a UNIQUE index to be applied to columns which allow NULL values, in which case two rows are allowed to be identical if they both contain a NULL value (the rationale here is that NULL is considered not equal to itself). Depending on your application, however, you may find this undesirable: if you wish to prevent this, you should disallow NULL values in the relevant columns.

• PRIMARY acts exactly like a UNIQUE index, except that it is always named 'PRIMARY', and there may be only one on a table (and there should always be one; though some database systems don't enforce this). A PRIMARY index is intended as a primary means to uniquely identify any row in the table, so unlike UNIQUE it should not be used on any columns which allow NULL values. Your PRIMARY index should be on the smallest number of columns that are sufficient to uniquely identify a row. Often, this is just one column containing a unique auto-incremented number, but if there is anything else that can uniquely identify a row, such as "countrycode" in a list of countries, you can use that instead.

  Some database systems (such as MySQL's InnoDB) will store a table's records on disk in the order in which they appear in the PRIMARY index.

• FULLTEXT indexes are different from all of the above, and their behaviour differs significantly between database systems. FULLTEXT indexes are only useful for full text searches done with the MATCH() / AGAINST() clause, unlike the above three - which are typically implemented internally using b-trees (allowing for selecting, sorting or ranges starting from left most column) or hash tables (allowing for selection starting from left most column).

  Where the other index types are general-purpose, a FULLTEXT index is specialised, in that it serves a narrow purpose: it's only used for a "full text search" feature.

Similarities

• All of these indexes may have more than one column in them.

• With the exception of FULLTEXT, the column order is significant: for the index to be useful in a query, the query must use columns from the index starting from the left - it can't use just the second, third or fourth part of an index, unless it is also using the previous columns in the index to match static values. (For a FULLTEXT index to be useful to a query, the query must use all columns of the index.)

A bug in the compiler/IDE

I recently had this problem, and it turned out it was a bug in Visual Studio Express 2013. I had to remove a source file from the project and re-add it to overcome the bug.

Steps to try if you believe it could be a bug in compiler/IDE:

• Clean the project (some IDEs have an option to do this, you can also manually do it by deleting the object files)
• Try start a new project, copying all source code from the original one.

The SQLite database engine

• self-contained
• serverless
• zero-configuration
• transactional
• cross platform Unix (Linux and Mac OS X), OS/2, and Windows (Win32 and WinCE) are supported out of the box. Easy to port to other systems.
• faster than heck

With library for most popular languages

• .Net
• perl

To make the text portion of a ComboBox non-editable, set the DropDownStyle property to "DropDownList". The ComboBox is now essentially select-only for the user. You can do this in the Visual Studio designer, or in C# like this:

stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList;

Link to the documentation for the ComboBox DropDownStyle property on MSDN.

From pandas version 0.18+ filtering a series can also be done as below

test = {
383:    3.000000,
663:    1.000000,
726:    1.000000,
737:    9.000000,
833:    8.166667
}

pd.Series(test).where(lambda x : x!=1).dropna()

this worker for me

git clone <repository> .

When I did this for a navigation database built from ARINC424 I did a fair amount of testing and looking back at the code, I used a DECIMAL(18,12) (Actually a NUMERIC(18,12) because it was firebird).

Floats and doubles aren't as precise and may result in rounding errors which may be a very bad thing. I can't remember if I found any real data that had problems - but I'm fairly certain that the inability to store accurately in a float or a double could cause problems

The point is that when using degrees or radians we know the range of the values - and the fractional part needs the most digits.

The MySQL Spatial Extensions are a good alternative because they follow The OpenGIS Geometry Model. I didn't use them because I needed to keep my database portable.

UPDATE: This list is getting a little out dated (it was generated with Xcode 4.1). You should run the command suggested by dunedin15.

dunedin15's answer can give inaccurate results for some edge-cases, such as when debugging build settings of a static lib for an Archive build, see Slipp D. Thompson's answer for a more robust output.

Follow simple steps:

1. Add flutter_launcher_icons Plugin to pubspec.yaml

e.g.

dev_dependencies: 
  flutter_test:
    sdk: flutter

  flutter_launcher_icons: "^0.8.1"

flutter_icons:
  image_path: "icon/icon.png" 
  android: true
  ios: true

2. Prepare an app icon for the specified path. e.g. icon/icon.png

3. Execute command on the terminal to Create app icons:

$ flutter pub get

$ flutter pub run flutter_launcher_icons:main

To check check all available options and to set different icons for android and iOS please refer this

Update:

flutter_launcher_icons 0.8.0 Version (12th Sept 2020) has Added flavours support

Flavors are typically used to build your app for different environments such as dev and prod

The community has written some articles and packages you might find useful. These articles address flavors for both iOS and Android.

Hope this will helps others.

For example, you have a doc with three fields:

PUT movie/_doc/1
{
  "name":"The Lion King",
  "language":"English",
  "score":"9.3"
}

If you want to return name and score you can use the following command:

GET movie/_doc/1?_source_includes=name,score

If you want to get some fields which match a pattern:

GET movie/_doc/1?_source_includes=*re

Maybe exclude some fields:

GET movie/_doc/1?_source_excludes=score

I tried to write up 3 following functions, you can test them for different cases of yours. This is the data I tested with:

Function getLastRow1 and getLastRow2 will return 0 for column B Function getLastRow3 will return 1 for column B

Depend on your case, you will tweak them for your needs.

function getLastRow1(sheet, column) {
  var data = sheet.getRange(1, column, sheet.getLastRow()).getValues();

  while(typeof data[data.length-1] !== 'undefined'
     && data[data.length-1][0].length === 0){ 
    data.pop();
  }
  return data.length;
}

function test() {
  var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet6');
  Logger.log('Cách 1');
  Logger.log("Dòng cu?i cùng c?a c?t A là: " + getLastRow1(sh, 1));
  Logger.log("Dòng cu?i cùng c?a c?t B là: " + getLastRow1(sh, 2));
  Logger.log("Dòng cu?i cùng c?a c?t C là: " + getLastRow1(sh, 3));
  Logger.log("Dòng cu?i cùng c?a c?t D là: " + getLastRow1(sh, 4));
  Logger.log("Dòng cu?i cùng c?a c?t E là: " + getLastRow1(sh, 5));
  Logger.log('Cách 2');  
  Logger.log("Dòng cu?i cùng c?a c?t A là: " + getLastRow2(sh, 1));
  Logger.log("Dòng cu?i cùng c?a c?t B là: " + getLastRow2(sh, 2));
  Logger.log("Dòng cu?i cùng c?a c?t C là: " + getLastRow2(sh, 3));
  Logger.log("Dòng cu?i cùng c?a c?t D là: " + getLastRow2(sh, 4));
  Logger.log("Dòng cu?i cùng c?a c?t E là: " + getLastRow2(sh, 5));
  Logger.log('Cách 3');
  Logger.log("Dòng cu?i cùng c?a c?t A là: " + getLastRow3(sh, 'A'));
  Logger.log("Dòng cu?i cùng c?a c?t B là: " + getLastRow3(sh, 'B'));
  Logger.log("Dòng cu?i cùng c?a c?t C là: " + getLastRow3(sh, 'C'));
  Logger.log("Dòng cu?i cùng c?a c?t D là: " + getLastRow3(sh, 'D'));
  Logger.log("Dòng cu?i cùng c?a c?t E là: " + getLastRow3(sh, 'E'));

}

function getLastRow2(sheet, column) {
  var lr = sheet.getLastRow();
  var data = sheet.getRange(1, column, lr).getValues();

  while(lr > 0 && sheet.getRange(lr , column).isBlank()) {
    lr--;
  }

  return lr;
}

function getLastRow3(sheet, column) {
  var lastRow = sheet.getLastRow();
  var range = sheet.getRange(column + lastRow);
  if (range.getValue() !== '') {
    return lastRow;
  } else {
    return range.getNextDataCell(SpreadsheetApp.Direction.UP).getRow();
  } 
}

You can be specific by testing for not valid characters. This will return true for anything not alphanumeric and space:

var specials = /[^A-Za-z 0-9]/g;
return specials.test(input.val());

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

Code example:

MainWindow.h

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

MainWindow.cpp

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

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

This is my query to find all those that are NOT number :

Select myVarcharField
From myTable
where not REGEXP_LIKE(myVarcharField, '^(-)?\d+(\.\d+)?$', '')
and not REGEXP_LIKE(myVarcharField, '^(-)?\d+(\,\d+)?$', '');

In my field I've . and , decimal numbers sadly so had to take that into account, else you only need one of the restriction.

We can use the rank() window function (where you would choose the rank = 1) rank just adds a number for every row of a group (in this case it would be the hour)

here's an example. ( from https://github.com/jaceklaskowski/mastering-apache-spark-book/blob/master/spark-sql-functions.adoc#rank )

val dataset = spark.range(9).withColumn("bucket", 'id % 3)

import org.apache.spark.sql.expressions.Window
val byBucket = Window.partitionBy('bucket).orderBy('id)

scala> dataset.withColumn("rank", rank over byBucket).show
+---+------+----+
| id|bucket|rank|
+---+------+----+
|  0|     0|   1|
|  3|     0|   2|
|  6|     0|   3|
|  1|     1|   1|
|  4|     1|   2|
|  7|     1|   3|
|  2|     2|   1|
|  5|     2|   2|
|  8|     2|   3|
+---+------+----+

Git 1.8.2 features a new option ,--remote, that will enable exactly this behavior. Running

git submodule update --rebase --remote

will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

(This was copied from this answer.)

Add arm64 to the target's valid architectures. Looks like it adds x86-64 architecture to simulator valid architectures as well.

My comment was deleted because I provided a link to a similar question I answered here. Ergo, I'll answer it more descriptively this time. Here goes.

You could do this easily by creating a CreateRoles method in your startup class. This helps check if the roles are created, and creates the roles if they aren't; on application startup. Like so.

private async Task CreateRoles(IServiceProvider serviceProvider)
    {
        //initializing custom roles 
        var RoleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
        var UserManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
        string[] roleNames = { "Admin", "Manager", "Member" };
        IdentityResult roleResult;

        foreach (var roleName in roleNames)
        {
            var roleExist = await RoleManager.RoleExistsAsync(roleName);
            if (!roleExist)
            {
                //create the roles and seed them to the database: Question 1
                roleResult = await RoleManager.CreateAsync(new IdentityRole(roleName));
            }
        }

        //Here you could create a super user who will maintain the web app
        var poweruser = new ApplicationUser
        {

            UserName = Configuration["AppSettings:UserName"],
            Email = Configuration["AppSettings:UserEmail"],
        };
    //Ensure you have these values in your appsettings.json file
        string userPWD = Configuration["AppSettings:UserPassword"];
        var _user = await UserManager.FindByEmailAsync(Configuration["AppSettings:AdminUserEmail"]);

       if(_user == null)
       {
            var createPowerUser = await UserManager.CreateAsync(poweruser, userPWD);
            if (createPowerUser.Succeeded)
            {
                //here we tie the new user to the role
                await UserManager.AddToRoleAsync(poweruser, "Admin");

            }
       }
    }

and then you could call the CreateRoles(serviceProvider).Wait(); method from the Configure method in the Startup class. ensure you have IServiceProvider as a parameter in the Configure class.

Using role-based authorization in a controller to filter user access: Question 2

You can do this easily, like so.

[Authorize(Roles="Manager")]
public class ManageController : Controller
{
   //....
}

You can also use role-based authorization in the action method like so. Assign multiple roles, if you will

[Authorize(Roles="Admin, Manager")]
public IActionResult Index()
{
/*
 .....
 */ 
}

While this works fine, for a much better practice, you might want to read about using policy based role checks. You can find it on the ASP.NET core documentation here, or this article I wrote about it here

This can be done by using the unbind function.

$('#myimage').unbind('click');

You can add multiple event handlers to the same object and event in jquery. This means adding a new one doesn't replace the old ones.

There are several strategies for changing event handlers, such as event namespaces. There are some pages about this in the online docs.

Look at this question (that's how I learned of unbind). There is some useful description of these strategies in the answers.

How to read bound hover callback functions in jquery

Dispatching and action inside of reducer seems occurs bug.

I made a simple counter example using useReducer which "INCREASE" is dispatched then "SUB" also does.

In the example I expected "INCREASE" is dispatched then also "SUB" does and, set cnt to -1 and then continue "INCREASE" action to set cnt to 0, but it was -1 ("INCREASE" was ignored)

See this: https://codesandbox.io/s/simple-react-context-example-forked-p7po7?file=/src/index.js:144-154

let listener = () => {
  console.log("test");
};
const middleware = (action) => {
  console.log(action);
  if (action.type === "INCREASE") {
    listener();
  }
};

const counterReducer = (state, action) => {
  middleware(action);
  switch (action.type) {
    case "INCREASE":
      return {
        ...state,
        cnt: state.cnt + action.payload
      };
    case "SUB":
      return {
        ...state,
        cnt: state.cnt - action.payload
      };
    default:
      return state;
  }
};

const Test = () => {
  const { cnt, increase, substract } = useContext(CounterContext);

  useEffect(() => {
    listener = substract;
  });

  return (
    <button
      onClick={() => {
        increase();
      }}
    >
      {cnt}
    </button>
  );
};

{type: "INCREASE", payload: 1}
{type: "SUB", payload: 1}
// expected: cnt: 0
// cnt = -1

Finding of week number for each date of a month (considering Monday as beginning of the week)

Keep the first date of month contant $B$13

=WEEKNUM(B18,2)-WEEKNUM($B$13,2)+1

WEEKNUM(B18,2) - returns the week number of the date mentioned in cell B18

WEEKNUM($B$13,2) - returns the week number of the 1st date of month in cell B13

As I commented you need to use a StringIO object and decode i.e c=pd.read_csv(io.StringIO(s.decode("utf-8"))) if using requests, you need to decode as .content returns bytes if you used .text you would just need to pass s as is s = requests.get(url).text c = pd.read_csv(StringIO(s)).

A simpler approach is to pass the correct url of the raw data directly to read_csv, you don't have to pass a file like object, you can pass a url so you don't need requests at all:

c = pd.read_csv("https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv")

print(c)

Output:

                              Country         Region
0                             Algeria         AFRICA

From the docs:

filepath_or_buffer :

string or file handle / StringIO The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. For instance, a local file could be file ://localhost/path/to/table.csv

The last inserted record can be queried using this assuming you have the "id" as the primary key:

SELECT timestamp,value,card FROM my_table WHERE id=(select max(id) from my_table)

Assuming every new row inserted will use the highest integer value for the table's id.

Unfortunately the Windows Mobile Device Center stopped working out of the box after the Creators Update for Windows 10. The application won't open and therefore it's impossible to get the sync working. In order to get it running now we need to modify the ActiveSync registry settings. Create a BAT file with the following contents and run it as administrator:

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\RapiMgr /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WcesComm /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

Restart the computer and everything should work.

Back with .Net 1.1 obfuscation was essential: decompiling code was easy, and you could go from assembly, to IL, to C# code and have it compiled again with very little effort.

Now with .Net 3.5 I'm not at all sure. Try decompiling a 3.5 assembly; what you get is a long long way from compiling.

Add the optimisations from 3.5 (far better than 1.1) and the way anonymous types, delegates and so on are handled by reflection (they are a nightmare to recompile). Add lambda expressions, compiler 'magic' like Linq-syntax and var, and C#2 functions like yield (which results in new classes with unreadable names). Your decompiled code ends up a long long way from compilable.

A professional team with lots of time could still reverse engineer it back again, but then the same is true of any obfuscated code. What code they got out of that would be unmaintainable and highly likely to be very buggy.

I would recommend key-signing your assemblies (meaning if hackers can recompile one they have to recompile all) but I don't think obfuscation's worth it.

Why don't you want to remove the multiple attribute? The entire purpose of that attribute is to specify to the browser that multiple values may be selected from the given select element. If only a single value should be selected, remove the attribute and the browser will know to allow only a single selection.

Use the tools you have, that's what they're for.

I know this post is old but I just wanted to add my answer!

You said to log a user out WITHOUT directing... this method DOES redirect but it returns the user to the page they were on! here's my implementation:

// every page with logout button
<?php
        // get the full url of current page
        $page = $_SERVER['PHP_SELF'];
        // find position of the last '/'
        $file_name_begin_pos = strripos($page, "/");
        // get substring from position to end 
        $file_name = substr($page, ++$fileNamePos);
    }
?>

// the logout link in your html
<a href="logout.php?redirect_to=<?=$file_name?>">Log Out</a>

// logout.php page
<?php
    session_start();
    $_SESSION = array();
    session_destroy();
    $page = "index.php";
    if(isset($_GET["redirect_to"])){
        $file = $_GET["redirect_to"];
        if ($file == "user.php"){
            // if redirect to is a restricted page, redirect to index
            $file = "index.php";
        }
    }
    header("Location: $file");
?>

and there we go!

the code that gets the file name from the full url isn't bug proof. for example if query strings are involved with un-escaped '/' in them, it will fail.

However there are many scripts out there to get the filename from url!

Happy Coding!

Your logic is slightly off. The second || should be &&:

if ((!isset($action)) || ($action != "add" && $action != "delete"))

You can see why your original line fails by trying out a sample value. Let's say $action is "delete". Here's how the condition reduces down step by step:

// $action == "delete"
if ((!isset($action)) || ($action != "add" || $action != "delete"))
if ((!true) || ($action != "add" || $action != "delete"))
if (false || ($action != "add" || $action != "delete"))
if ($action != "add" || $action != "delete")
if (true || $action != "delete")
if (true || false)
if (true)

Oops! The condition just succeeded and printed "error", but it was supposed to fail. In fact, if you think about it, no matter what the value of $action is, one of the two != tests will return true. Switch the || to && and then the second to last line becomes if (true && false), which properly reduces to if (false).

There is a way to use || and have the test work, by the way. You have to negate everything else using De Morgan's law, i.e.:

if ((!isset($action)) || !($action == "add" || $action == "delete"))

You can read that in English as "if action is not (either add or remove), then".

I'd argue that reading from the file is the most reliable way to establish whether it contains more data. It could be a pipe, or another process might be appending data to the file etc.

If you know that's not an issue, you could use something like:

f.tell() == os.fstat(f.fileno()).st_size

In my case, I missed to write @JsonProperty annotation in one of the fields which was causing this error.

Here 2 ways to do it:

set.seed(1)
tt <- sample(letters,100,rep=TRUE)

## using table
table(tt)
tt
a b c d e f g h i j k l m n o p q r s t u v w x y z 
2 3 3 3 2 4 6 1 6 5 6 4 7 2 2 2 5 4 5 3 8 4 5 4 3 1 
## using tapply
tapply(tt,tt,length)
a b c d e f g h i j k l m n o p q r s t u v w x y z 
2 3 3 3 2 4 6 1 6 5 6 4 7 2 2 2 5 4 5 3 8 4 5 4 3 1 

See std::clock() function.

const clock_t begin_time = clock();
// do something
std::cout << float( clock () - begin_time ) /  CLOCKS_PER_SEC;

If you want calculate execution time for self ( not for user ), it is better to do this in clock ticks ( not seconds ).
