Finally this worked for me

private String buildBasicAuthorizationString(String username, String password) {

    String credentials = username + ":" + password;
    return "Basic " + new String(Base64.encode(credentials.getBytes(), Base64.NO_WRAP));
}

I'm Using Ubuntu and with the following command worked

apt-get install --yes zip unzip

Fix:

I chose the "ISAPI & CGI Restrictions" after clicking the server name (not the site name) in IIS Manager, and right clicked the "ASP.NET v4.0.30319" lines and chose "Allow".

After turning on ASP.NET from "Programs and Features > Turn Windows features on or off", you must install ASP.NET from the Windows command prompt. The MIME types don't ever show up, but after doing this command, I noticed these extensions showed up under the IIS web site "Handler Mappings" section of IIS Manager.

However, I still got this error. But if you do what I mentioned for the "Fix", this will go away.

HTTP Error 404.2 - Not Found
The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server.

        combo1.DisplayMember = "Text";
        combo1.ValueMember = "Value";   
        combo1.Items.Add(new { Text = "someText"), Value = "someValue") });
        dynamic item = combo1.Items[combo1.SelectedIndex];
        var itemValue = item.Value;
        var itemText = item.Text;

Unfortunatly "combo1.SelectedValue" does not work, i did not want to bind my combobox with any source, so i came up with this solution. Maybe it will help someone.

I've mixed and matched from different schemes I've seen and based on the tooling I'm using.
So my completed branch name would be:

name/feature/issue-tracker-number/short-description

which would translate to:

mike/blogs/RSSI-12/logo-fix

The parts are separated by forward slashes because those get interpreted as folders in SourceTree for easy organization. We use Jira for our issue tracking so including the number makes it easier to look up in the system. Including that number also makes it searchable when trying to find that issue inside Github when trying to submit a pull request.

If you are using curl versions curl-7.19.7-46.el6.x86_64 or older. Please provide an option as -k1 (small K1).

I meet the same problem, @progrAmmar enlightened me, "took a closer look at the user table in mysql database".

My problem is not ssl_type, instead of the first field:Host. I changed the value by using

update user set Host='localhost' where User='root' and Host='%';

in mysqld_safe --skip-grant-tables model.

Then it works well.

There is no agreed upon naming convention for HTML and CSS. But you could structure your nomenclature around object design. More specifically what I call Ownership and Relationship.

Ownership

Keywords that describe the object, could be separated by hyphens.

car-new-turned-right

Keywords that describe the object can also fall into four categories (which should be ordered from left to right): Object, Object-Descriptor, Action, and Action-Descriptor.

car - a noun, and an object
new - an adjective, and an object-descriptor that describes the object in more detail
turned - a verb, and an action that belongs to the object
right - an adjective, and an action-descriptor that describes the action in more detail

Note: verbs (actions) should be in past-tense (turned, did, ran, etc).

Relationship

Objects can also have relationships like parent and child. The Action and Action-Descriptor belongs to the parent object, they don't belong to the child object. For relationships between objects you could use an underscore.

car-new-turned-right_wheel-left-turned-left

• car-new-turned-right (follows the ownership rule)
• wheel-left-turned-left (follows the ownership rule)
• car-new-turned-right_wheel-left-turned-left (follows the relationship rule)

Final notes:

• Because CSS is case-insensitive, it's better to write all names in lower-case (or upper-case); avoid camel-case or pascal-case as they can lead to ambiguous names.
• Know when to use a class and when to use an id. It's not just about an id being used once on the web page. Most of the time, you want to use a class and not an id. Web components like (buttons, forms, panels, ...etc) should always use a class. Id's can easily lead to naming conflicts, and should be used sparingly for namespacing your markup. The above concepts of ownership and relationship apply to naming both classes and ids, and will help you avoid naming conflicts.
• If you don't like my CSS naming convention, there are several others as well: Structural naming convention, Presentational naming convention, Semantic naming convention, BEM naming convention, OCSS naming convention, etc.

This has been partially answered here: MySQL Like multiple values

I advise against

$search = explode( ' ', $search );

and input them directly into the SQL query as this makes prone to SQL inject via the search bar. You will have to escape the characters first in case they try something funny like: "--; DROP TABLE name;

$search = str_replace('"', "''", search );

But even that is not completely safe. You must try to use SQL prepared statements to be safer. Using the regular expression is much easier to build a function to prepare and create what you want.

function makeSQL_search_pattern($search) {
    search_pattern = false;
    //escape the special regex chars
    $search = str_replace('"', "''", $search);
    $search = str_replace('^', "\\^", $search);
    $search = str_replace('$', "\\$", $search);
    $search = str_replace('.', "\\.", $search);
    $search = str_replace('[', "\\[", $search);
    $search = str_replace(']', "\\]", $search);
    $search = str_replace('|', "\\|", $search);
    $search = str_replace('*', "\\*", $search);
    $search = str_replace('+', "\\+", $search);
    $search = str_replace('{', "\\{", $search);
    $search = str_replace('}', "\\}", $search);
    $search = explode(" ", $search);
    for ($i = 0; $i < count($search); $i++) {
        if ($i > 0 && $i < count($search) ) {
           $search_pattern .= "|";
        }
        $search_pattern .= $search[$i];
    }
    return search_pattern;
}

$search_pattern = makeSQL_search_pattern($search);
$sql_query = "SELECT name FROM Products WHERE name REGEXP :search LIMIT 6"
$stmt = pdo->prepare($sql_query);
$stmt->bindParam(":search", $search_pattern, PDO::PARAM_STR);
$stmt->execute();

I have not tested this code, but this is what I would do in your case. I hope this helps.

To list files based on size in asending order.

find ./ -size +1000M -exec ls -tlrh {} \; |awk -F" " '{print $5,$9}'  | sort -n\

controlName.CssClass="CSS Class Name";

working example follows below

txtBank.CssClass = "csError";

Edit - this answer was for an earlier version of Charles. See @semicircle21 answer below for the proper steps for v3.10.x -- much easier than this approach too... :-)

For what it's worth here are the step by step instructions for this. They should apply equally well in iOS too:

1. Open Charles
2. Go to Proxy > Proxy Settings > SSL
3. Check “Enable SSL Proxying”
4. Select “Add location” and enter the host name and port (if needed)
5. Click ok and make sure the option is checked
6. Download the Charles cert from here: Charles cert >
7. Send that file to yourself in an email.
8. Open the email on your device and select the cert
9. In “Name the certificate” enter whatever you want
10. Click OK and you should get a message that the certificate was installed

You should then be able to see the SSL files in Charles. If you want to intercept and change the values you can use the "Map Local" tool which is really awesome:

1. In Charles go to Tools > Map Local
2. Select "Add entry"
3. Enter the values for the file you want to replace
4. In “Local path” select the file you want the app to load instead
5. Click OK
6. Make sure the entry is selected and click OK
7. Run your app
8. You should see in “Notes” that your file loads instead of the live one

To change the Path, you can set a new Path to an Enviroment-Variable named: VAGRANT_HOME

export VAGRANT_HOME=my/new/path/goes/here/

Thats maybe nice if you want to have those vagrant-Images on another HDD.

More Information here in the Documentations: http://docs.vagrantup.com/v2/other/environmental-variables.html

To match a substring inside parentheses excluding any inner parentheses you may use

\(([^()]*)\)

pattern. See the regex demo.

In JavaScript, use it like

var rx = /\(([^()]*)\)/g;

Pattern details

• \( - a ( char
• ([^()]*) - Capturing group 1: a negated character class matching any 0 or more chars other than ( and )
• \) - a ) char.

To get the whole match, grab Group 0 value, if you need the text inside parentheses, grab Group 1 value.

Most up-to-date JavaScript code demo (using matchAll):

const strs = ["I expect five hundred dollars ($500).", "I expect.. :( five hundred dollars ($500)."];
const rx = /\(([^()]*)\)/g;
strs.forEach(x => {
  const matches = [...x.matchAll(rx)];
  console.log( Array.from(matches, m => m[0]) ); // All full match values
  console.log( Array.from(matches, m => m[1]) ); // All Group 1 values
});

Legacy JavaScript code demo (ES5 compliant):

var strs = ["I expect five hundred dollars ($500).", "I expect.. :( five hundred dollars ($500)."];
var rx = /\(([^()]*)\)/g;


for (var i=0;i<strs.length;i++) {
  console.log(strs[i]);

  // Grab Group 1 values:
  var res=[], m;
  while(m=rx.exec(strs[i])) {
    res.push(m[1]);
  }
  console.log("Group 1: ", res);

  // Grab whole values
  console.log("Whole matches: ", strs[i].match(rx));
}

Adding to the top voted answer and many ones above stressing the "more generic, better", I would like to dig a little bit more.

Map is the structure contract while HashMap is an implementation providing its own methods to deal with different real problems: how to calculate index, what is the capacity and how to increment it, how to insert, how to keep the index unique, etc.

Let's look into the source code:

In Map we have the method of containsKey(Object key):

boolean containsKey(Object key);

JavaDoc:

boolean java.util.Map.containsValue(Object value)

Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.

Parameters:value

value whose presence in this map is to betested

Returns:true

if this map maps one or more keys to the specified

valueThrows:

ClassCastException - if the value is of an inappropriate type for this map (optional)

NullPointerException - if the specified value is null and this map does not permit null values (optional)

It requires its implementations to implement it, but the "how to" is at its freedom, only to ensure it returns correct.

In HashMap:

public boolean containsKey(Object key) {
    return getNode(hash(key), key) != null;
}

It turns out that HashMap uses hashcode to test if this map contains the key. So it has the benefit of hash algorithm.

Here is what I did recently in PHP on one of my bigger systems:

1. User inputs newsletter text and selects the recipients (which generates a query to retrieve the email addresses for later).

2. Add the newsletter text and recipients query to a row in mysql table called *email_queue*

   • (The table email_queue has the columns "to" "subject" "body" "priority")

3. I created another script, which runs every minute as a cron job. It uses the SwiftMailer class. This script simply:

   • during business hours, sends all email with priority == 0

   • after hours, send other emails by priority

Depending on the hosts settings, I can now have it throttle using standard swiftmailers plugins like antiflood and throttle...

$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50, 30));

and

$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin( 100, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE ));

etc, etc..

I have expanded it way beyond this pseudocode, with attachments, and many other configurable settings, but it works very well as long as your server is setup correctly to send email. (Probably wont work on shared hosting, but in theory it should...) Swiftmailer even has a setting

$message->setReturnPath

Which I now use to track bounces...

Happy Trails! (Happy Emails?)

Probably the simplest way is to use the InputBox method of the Microsoft.VisualBasic.Interaction class:

[void][Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic')

$title = 'Demographics'
$msg   = 'Enter your demographics:'

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title)

Check out copyOfRange; and example:

int[] arr2 = Arrays.copyOfRange(arr,0,3);

Use a named fifo.

#!/bin/sh
mkfifo trigger
while true; do
    read < trigger
    long_running_task
done

Then whenever you want to start the long running task, simply write a newline (nonblocking to the trigger file.

As long as your input is smaller than PIPE_BUF and it's a single write() operation, you can write arguments into the fifo and have them show up as $REPLY in the script.

Using this regular expression you can validate different kinds of Date/Time samples, just a little change is needed.

^\d\d\d\d/(0?[1-9]|1[0-2])/(0?[1-9]|[12][0-9]|3[01]) (00|[0-9]|1[0-9]|2[0-3]):([0-9]|[0-5][0-9]):([0-9]|[0-5][0-9])$ -->validate this: 2018/7/12 13:00:00

for your format you cad change it to:

^(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[0-2])/\d\d$ --> validates this: 11/12/98

First of all, the space complexity of this loop is O(1) (the input is customarily not included when calculating how much storage is required by an algorithm).

So the question that I have is if its possible that an algorithm has different time complexity from space complexity?

Yes, it is. In general, the time and the space complexity of an algorithm are not related to each other.

Sometimes one can be increased at the expense of the other. This is called space-time tradeoff.

1. Add an exit handler that closes all the bars.
2. __del__() gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.
3. If __init__() raises an exception then the object is assumed to be incomplete and __del__() won't be invoked.

You can try to use a WITH clause.

WITH vars AS (SELECT 42 AS answer, 3.14 AS appr_pi)
SELECT t.*, vars.answer, t.radius*vars.appr_pi
FROM table AS t, vars;

It is almost fine. Just have:

Player[] thePlayers = new Player[playerCount + 1];

And let the loop be:

for(int i = 0; i < thePlayers.length; i++)

And note that java convention dictates that names of methods and variables should start with lower-case.

Update: put your method within the class body.

No. As the documentation shows, you can only grant access to one object at a time.

I think this code gets the same and is easier to read.

SELECT <some columns> 
FROM mytable
<maybe some joins here>
WHERE date >= (SELECT date from mytable)
OR date <= (SELECT date from mytable);

I managed to overcome this by doing the following.

1. Pick the font size you like for the current view you have (Make sure it looks good for the current device you are using in the simulator).

2. import { Dimensions } from 'react-native' and define the width outside of the component like so: let width = Dimensions.get('window').width;

3. Now console.log(width) and write it down. If your good looking font size is 15 and your width is 360 for example, then take 360 and divide by 15 ( = 24). This is going to be the important value that is going to adjust to different sizes.

   Use this number in your styles object like so: textFontSize: { fontSize = width / 24 },...

Now you have a responsive fontSize.

For MS T-SQL Server, I suggest looking into creating an index with the "include" statement. Uniqueness is not required, neither is the physical sorting of data associated with a clustered index. The "Index ... Include ()" creates a separate physical data storage automatically maintained by the system. It is conceptually very similar to an Oracle Materialized View.

As mentioned, the C compiler will add padding for alignment requirements. These requirements often have to do with the memory subsystem. Some types of computers can only access memory lined up to some 'nice' value, like 4 bytes. This is often the same as the word length. Thus, the C compiler may align fields in your structure to this value to make them easier to access (e.g., 4 byte values should be 4 byte aligned) Further, it may pad the bottom of the structure to line up data which follows the structure. I believe there are other reasons as well. More info can be found at this wikipedia page.

i've solve all with

.setInputType(InputType.TYPE_CLASS_NUMBER);

for see clear data and

.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

for see the dots (if the data is a number, it isn't choice che other class)

Best one besides Vi? Vim.

Suppose

a = ['a', 'b', 'c', 3, 4, 'd', 6, 7, 8]

and the list of indexes is stored in

b= [0, 1, 2, 4, 6, 7, 8]

then a simple one-line solution will be

c = [a[i] for i in b]

I had the same problem and found out that I had forgotten to include the script in the file which I want to include in the live site.

Also, you should try this:

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));

Eventhough there are several methods, The best way (most efficient and easiest) is using db.dropDatabase()

I eventually figured it out. Place:

import warnings
warnings.filterwarnings('ignore')

inside ~/.ipython/profile_default/startup/disable-warnings.py. I'm leaving this question and answer for the record in case anyone else comes across the same issue.

Quite often it is useful to see a warning once. This can be set by:

warnings.filterwarnings(action='once')

restart MySQL server with --skip-grant-tables option And then set a new root password

$ mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET password=PASSWORD("NEWPASSWORD") WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit

Now if you need, you can update mysql.user table(field password_expired='N') not to expire the password.

Can do this in jQuery. Try all options .height(), .innerHeight() or .outerHeight().

$('document').ready(function() {
    $('#right_div').css({'height': $('#left_div').innerHeight()});
});

Hope this helps. Thanks!!

I'm not aware of a tool that does this well but I've seen a variety of homegrown solutions. The common thread of these is to minimise the binary data under version control and maximise textual data to leverage the power of conventional scc systems. To do this:

• Treat the workbook like any other application. Seperate logic, config and data.
• Separate code from the workbook.
• Build the UI programmatically.
• Write a build script to reconstruct the workbook.

Here's a blog post explains it very well:

http://panks.me/posts/2013/11/install-gdb-on-os-x-mavericks-from-source/

And the way I get it working:

1. Create a coding signing certificate via KeyChain Access:

   1.1 From the Menu, select KeyChain Access > Certificate Assistant > Create a Certificate...

   1.2 Follow the wizard to create a certificate and let's name it gdb-cert, the Identity Type is Self Signed Root, and the Certificate Type is Code Signing and select the Let me override defaults.

   1.3 Click several times on Continue until you get to the Specify a Location For The Certificate screen, then set Keychain to System.

2. Install gdb via Homebrew: brew install gdb

3. Restart taskgated: sudo killall taskgated && exit

4. Reopen a Terminal window and type sudo codesign -vfs gdb-cert /usr/local/bin/gdb

Using JACOB call Office Word is a 100% perfect solution. But it only supports on Windows platform because need Office Word installed.

1. Download JACOB archive (the latest version is 1.19);
2. Add jacob.jar to your project classpath;
3. Add jacob-1.19-x32.dll or jacob-1.19-x64.dll (depends on your jdk version) to ...\Java\jdk1.x.x_xxx\jre\bin

4. Using JACOB API call Office Word to convert doc/docx to pdf.

   public void convertDocx2pdf(String docxFilePath) {
   File docxFile = new File(docxFilePath);
   String pdfFile = docxFilePath.substring(0, docxFilePath.lastIndexOf(".docx")) + ".pdf";
   
   if (docxFile.exists()) {
       if (!docxFile.isDirectory()) { 
           ActiveXComponent app = null;
   
           long start = System.currentTimeMillis();
           try {
               ComThread.InitMTA(true); 
               app = new ActiveXComponent("Word.Application");
               Dispatch documents = app.getProperty("Documents").toDispatch();
               Dispatch document = Dispatch.call(documents, "Open", docxFilePath, false, true).toDispatch();
               File target = new File(pdfFile);
               if (target.exists()) {
                   target.delete();
               }
               Dispatch.call(document, "SaveAs", pdfFile, 17);
               Dispatch.call(document, "Close", false);
               long end = System.currentTimeMillis();
               logger.info("============Convert Finished:" + (end - start) + "ms");
           } catch (Exception e) {
               logger.error(e.getLocalizedMessage(), e);
               throw new RuntimeException("pdf convert failed.");
           } finally {
               if (app != null) {
                   app.invoke("Quit", new Variant[] {});
               }
               ComThread.Release();
           }
       }
   }
   

   }

After much struggle with this same issue I was able to solve the problem by installing the 32 bit version of the 2010 Access Database Engine. For some reason the 64bit version generates this error...

You can use the HTML5 <mark> tag.

HTML:

<h1><mark>The Last Will and Testament of Eric Jones</mark></h1>

CSS:

mark
{
    background-color: green;
}

find / -exec grep -lR "{test-string}" {} \;

there is a .bat script to start it (python 2.7).

I wrote an article about emulating the Chip-8 system in JavaScript.

It's a great place to start as the system isn't very complicated, but you still learn how opcodes, the stack, registers, etc work.

I will be writing a longer guide soon for the NES.

Even though CMD is written down in the Dockerfile, it really is runtime information. Just like EXPOSE, but contrary to e.g. RUN and ADD. By this, I mean that you can override it later, in an extending Dockerfile, or simple in your run command, which is what you are experiencing. At all times, there can be only one CMD.

If you want to run multiple services, I indeed would use supervisor. You can make a supervisor configuration file for each service, ADD these in a directory, and run the supervisor with supervisord -c /etc/supervisor to point to a supervisor configuration file which loads all your services and looks like

[supervisord]
nodaemon=true

[include]
files = /etc/supervisor/conf.d/*.conf

If you would like more details, I wrote a blog on this subject here: http://blog.trifork.com/2014/03/11/using-supervisor-with-docker-to-manage-processes-supporting-image-inheritance/

Solved with Eclipse in the next way:

First of all, do a synchronisation of your folder to the project:

team -> synchronise

In the next view, team view, you can see all resources that you can commit to the SVN server.

So, select the resource folder of the resource that you want to ignore, and then you can ignore it using

team -> add to svn:ignore.

After that, in the confirmation window, do select the first option: "ignore by name".

For instance, If I want to ignore the target folder and their .class resources, I'll do synchronise, and in the synchronise view, I'll select the target folder. After that, I'll select

team->add

to svn:ignore and then I'll confirm the first option in the confirm window.

SELECT, INSERT, UPDATE, and DELETE commands frequently include WHERE clauses to specify filters that define the conditions each row in the source tables must meet to qualify for an SQL command. Parameters provide the filter values in the WHERE clauses.

You can use parameter markers to dynamically provide parameter values. The rules for which parameter markers and parameter names can be used in the SQL statement depend on the type of connection manager that the Execute SQL uses.

The following table lists examples of the SELECT command by connection manager type. The INSERT, UPDATE, and DELETE statements are similar. The examples use SELECT to return products from the Product table in AdventureWorks2012 that have a ProductID greater than and less than the values specified by two parameters.

EXCEL, ODBC, and OLEDB

SELECT* FROM Production.Product WHERE ProductId > ? AND ProductID < ?

ADO

SELECT * FROM Production.Product WHERE ProductId > ? AND ProductID < ?

ADO.NET

SELECT* FROM Production.Product WHERE ProductId > @parmMinProductID 
     AND ProductID < @parmMaxProductID

The examples would require parameters that have the following names: The EXCEL and OLED DB connection managers use the parameter names 0 and 1. The ODBC connection type uses 1 and 2. The ADO connection type could use any two parameter names, such as Param1 and Param2, but the parameters must be mapped by their ordinal position in the parameter list. The ADO.NET connection type uses the parameter names @parmMinProductID and @parmMaxProductID.

var datestr = '2012.08.10';
var timestamp = (new Date(datestr.split(".").join("-")).getTime())/1000;

The difference between the project operator (p) in relational algebra and the SELECT keyword in SQL is that if the resulting table/set has more than one occurrences of the same tuple, then p will return only one of them, while SQL SELECT will return all.

On upgrading to Xcode 8, I got a message to upgrade to recommended settings. I accepted and everything was updated. I started getting compile time issue :

Duplicate symbol for XXXX Duplicate symbol for XXXX Duplicate symbol for XXXX

A total of 143 errors. Went to Target->Build settings -> No Common Blocks -> Set it to NO. This resolved the issue. The issue was that the integrated projects had code blocks in common and hence was not able to compile it. Explanation can be found here.

Use the Expected Conditions provided by Selenium to wait for the WebElement.

While you debug, the client is not as fast as if you just run a unit test or a maven build. This means in debug mode the client has more time to prepare the element, but if the build is running the same code he is much faster and the WebElement your looking for is might not visible in the DOM of the Page.

Trust me with this, I had the same problem.

for example:

inClient.waitUntil(ExpectedConditions.visibilityOf(YourElement,2000))

This easy method calls wait after his call for 2 seconds on the visibility of your WebElement on DOM.

Since Visual Studio 2012, you can view the outline ( fields and methods) in the solution explorer by expanding the node corresponding to your file .

Ensure position is on your element and set the z-index to a value higher than the elements you want to cover.

element {
    position: fixed;
    z-index: 999;
}

div {
    position: relative;
    z-index: 99;
}

It will probably require some more work than that but it's a start since you didn't post any code.

This works fine...

android:maxLength="10"

this will accept only 10 characters.

SELECT COUNT(DISTINCT program_name) AS Count, program_type AS [Type] 
FROM cm_production 
WHERE push_number=@push_number 
GROUP BY program_type

Also you can try:

string.split('foo').join('bar');

I ultimately found nothing that would work across all my browsers and all DocTypes / browser rendering modes, except for using jQuery. So here is what I came up with.
It even takes rowspan into account.

function InitDivHeights() {
    var spacing = 10; // <-- Tune this value to match your tr/td spacing and padding.
    var rows = $('#MyTable tr');
    var heights = [];
    for (var i = 0; i < rows.length; i++)
        heights[i] = $(rows[i]).height();
    for (var i = 0; i < rows.length; i++) {
        var row = $(rows[i]);
        var cells = $('td', row);
        for (var j = 0; j < cells.length; j++) {
            var cell = $(cells[j]);
            var rowspan = cell.attr('rowspan') || 1;
            var newHeight = 0;
            for (var k = 0; (k < rowspan && i + k < heights.length); k++)
                newHeight += heights[i + k];
            $('div', cell).height(newHeight - spacing);
        }
    }
}
$(document).ready(InitDivHeights);

Tested in IE11 (Edge mode), FF42, Chrome44+. Not tested with nested tables.

You can also use:

@Scripts.RenderFormat("<script type=\"text/javascript\" src=\"{0}\"></script>", "~/bundles/mybundle")

To specify the format of your output in a scenario where you need to use Charset, Type, etc.

@jolly.exe

Nice example Jolly. I updated your version which limits the character length as opposed to the number of words. I also added setting the title to the real original innerHTML , so users can hover and see what is truncated.

HTML

<div id="stuff">a reallly really really long titleasdfasdfasdfasdfasdfasdfasdfadsf</div> 

JS

 function cutString(id){    
     var text = document.getElementById(id).innerHTML;         
     var charsToCutTo = 30;
        if(text.length>charsToCutTo){
            var strShort = "";
            for(i = 0; i < charsToCutTo; i++){
                strShort += text[i];
            }
            document.getElementById(id).title = "text";
            document.getElementById(id).innerHTML = strShort + "...";
        }            
     };

cutString('stuff'); 

$(document).ready(function(){ 
  $('#some-id').trigger('click'); 
});

did the trick.

I'm not sure if you can alter the original element but how about switch from using the id attr to something else like data-id? Then just read the value of data-id for your hash value and it won't jump.

My try is combined solution.

string = string.replace(',', '.').replace(/[^\d\.]/g, "").replace(/\./, "x").replace(/\./g, "").replace(/x/, ".");
string = Math.round( parseFloat(string) * 100) / 100;

First line solution from here: regex replacing multiple periods in floating number . It replaces comma "," with dot "." ; Replaces first comma with x; Removes all dots and replaces x back to dot.

Second line cleans numbers after dot.

Sometimes a BEFORE trigger can be replaced with an AFTER one, but this doesn't appear to be the case in your situation, for you clearly need to provide a value before the insert takes place. So, for that purpose, the closest functionality would seem to be the INSTEAD OF trigger one, as @marc_s has suggested in his comment.

Note, however, that, as the names of these two trigger types suggest, there's a fundamental difference between a BEFORE trigger and an INSTEAD OF one. While in both cases the trigger is executed at the time when the action determined by the statement that's invoked the trigger hasn't taken place, in case of the INSTEAD OF trigger the action is never supposed to take place at all. The real action that you need to be done must be done by the trigger itself. This is very unlike the BEFORE trigger functionality, where the statement is always due to execute, unless, of course, you explicitly roll it back.

But there's one other issue to address actually. As your Oracle script reveals, the trigger you need to convert uses another feature unsupported by SQL Server, which is that of FOR EACH ROW. There are no per-row triggers in SQL Server either, only per-statement ones. That means that you need to always keep in mind that the inserted data are a row set, not just a single row. That adds more complexity, although that'll probably conclude the list of things you need to account for.

So, it's really two things to solve then:

• replace the BEFORE functionality;

• replace the FOR EACH ROW functionality.

My attempt at solving these is below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  INSERT INTO sub (super_id)
  SELECT super_id FROM @new_super;
END;

This is how the above works:

1. The same number of rows as being inserted into sub1 is first added to super. The generated super_id values are stored in a temporary storage (a table variable called @new_super).

2. The newly inserted super_ids are now inserted into sub1.

Nothing too difficult really, but the above will only work if you have no other columns in sub1 than those you've specified in your question. If there are other columns, the above trigger will need to be a bit more complex.

The problem is to assign the new super_ids to every inserted row individually. One way to implement the mapping could be like below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    rownum   int IDENTITY (1, 1),
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  WITH enumerated AS (
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS rownum
    FROM inserted
  )
  INSERT INTO sub1 (super_id, other columns)
  SELECT n.super_id, i.other columns
  FROM enumerated AS i
  INNER JOIN @new_super AS n
  ON i.rownum = n.rownum;
END;

As you can see, an IDENTIY(1,1) column is added to @new_user, so the temporarily inserted super_id values will additionally be enumerated starting from 1. To provide the mapping between the new super_ids and the new data rows, the ROW_NUMBER function is used to enumerate the INSERTED rows as well. As a result, every row in the INSERTED set can now be linked to a single super_id and thus complemented to a full data row to be inserted into sub1.

Note that the order in which the new super_ids are inserted may not match the order in which they are assigned. I considered that a no-issue. All the new super rows generated are identical save for the IDs. So, all you need here is just to take one new super_id per new sub1 row.

If, however, the logic of inserting into super is more complex and for some reason you need to remember precisely which new super_id has been generated for which new sub row, you'll probably want to consider the mapping method discussed in this Stack Overflow question:

• Using merge..output to get mapping between source.id and target.id

JavaScript's Date object supports the ISO date format, so as long as you have access to the date string, you can do something like this:

> foo = new Date("2012-07-14T01:00:00+01:00")
Sat, 14 Jul 2012 00:00:00 GMT
> foo.toTimeString()
'17:00:00 GMT-0700 (MST)'

If you want the time string without the seconds and the time zone then you can call the getHours() and getMinutes() methods on the Date object and format the time yourself.

Here is a simple javascript solution which works in most cases:

document.getElementById("selectId").selectedIndex = "0";

To check whether the frame have been loaded, use onload function. Or put your main function in load: I recommend to use load when creating the iframe by js

 $('<iframe />', {
   src: url,
   id:  'receiver',
   frameborder: 1,
   load:function(){
     //put your code here, so that those code can be make sure to be run after the frame loaded
   }
   }).appendTo('body');

I don't think you can give a path to curl, but you can CD to the location, download and CD back.

cd target/path && { curl -O URL ; cd -; }

Or using subshell.

(cd target/path && curl -O URL)

Both ways will only download if path exists. -O keeps remote file name. After download it will return to original location.

If you need to set filename explicitly, you can use small -o option:

curl -o target/path/filename URL

Set it in the JAVA_OPTS variable in [path to tomcat]/bin/catalina.sh. Under windows there is a console where you can set it up or you use the catalina.bat.

Flipping the Default Coordinate System

Flipping in UIKit drawing modifies the backing CALayer to align a drawing environment having a LLO coordinate system with the default coordinate system of UIKit. If you only use UIKit methods and function for drawing, you shouldn’t need to flip the CTM. However, if you mix Core Graphics or Image I/O function calls with UIKit calls, flipping the CTM might be necessary.

Specifically, if you draw an image or PDF document by calling Core Graphics functions directly, the object is rendered upside-down in the view’s context. You must flip the CTM to display the image and pages correctly.

To flip a object drawn to a Core Graphics context so that it appears correctly when displayed in a UIKit view, you must modify the CTM in two steps. You translate the origin to the upper-left corner of the drawing area, and then you apply a scale translation, modifying the y-coordinate by -1. The code for doing this looks similar to the following:

CGContextSaveGState(graphicsContext);
CGContextTranslateCTM(graphicsContext, 0.0, imageHeight);
CGContextScaleCTM(graphicsContext, 1.0, -1.0);
CGContextDrawImage(graphicsContext, image, CGRectMake(0, 0, imageWidth, imageHeight));
CGContextRestoreGState(graphicsContext);

No.

A workaround is to overload with another method that doesn't have out / ref parameters, and which just calls your current method.

public bool SomeMethod(out string input)
{
    ...
}

// new overload
public bool SomeMethod()
{
    string temp;
    return SomeMethod(out temp);
}

If you have C# 7.0, you can simplify:

// new overload
public bool SomeMethod()
{
    return SomeMethod(out _);    // declare out as an inline discard variable
}

(Thanks @Oskar / @Reiner for pointing this out.)

row.IsNull("column")

What ultimately worked for me was the following steps:

1. Configure the Environment Injector Plugin: https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin
2. Goto to the /job//configure screen
3. In Build Environment section check "Inject environment variables to the build process"

It would be the highest available priority setting, and would usually only be used on box that was dedicated to running that specific program. It's actually high enough that it could cause starvation of the keyboard and mouse threads to the extent that they become unresponsive.

So basicly, if you have to ask, don't use it :)

Use the function IF :

=IF ( logical_test, value_if_true, value_if_false )

$diffPricePercent = (($actual * 100) / $itemCost) / $itemQty;

$itemCost and $itemQty are returning null or zero, check them what they come with to code from user input

also to check if it's not empty data add:

if (!empty($_POST['num1'])) {
    $itemQty = $_POST['num1'];
}

and you can check this link for POST validation before using it in variable

https://www.virendrachandak.com/techtalk/php-isset-vs-empty-vs-is_null/

what worked for me is converting the props.data to an array using data = Array.from(props.data); then I could use the data.map() function

Open index.php in www folder and set

$suppress_localhost = false;

This will prepend http://localhost/ to your project links

Bundler 2

If you need to update from bundler v1 to v2 follow this official guide.

For a fast solution:

1. In root fo your application run bundle config set path "/bundle" to add a custom path for bundler use, in this case I set /bundle, you can use whatever.

   1.2 [Alternative solution] You can use a bundler file (~/.bundle/config) also, to use this I recommend set bundler folders in environment, like a Docker image, for example. Here the official guide.

2. You don't need to delete your Gemfile.lock, It's a bad practice and this can cause other future problems. Commit Gemfile.lock normaly, sometimes you need to update your bundle with bundle install or install individual gem.

You can see all the configs for bundler version 2 here.

I like plugin https://github.com/hazzik/livequery It works without timers!

Simple usage

$('.some:visible').livequery( function(){ ... } );

But you need to fix a mistake. Replace line

$jQlq.registerPlugin('append', 'prepend', 'after', 'before', 'wrap', 'attr', 'removeAttr', 'addClass', 'removeClass', 'toggleClass', 'empty', 'remove', 'html', 'prop', 'removeProp');

to

$jQlq.registerPlugin('show', 'append', 'prepend', 'after', 'before', 'wrap', 'attr', 'removeAttr', 'addClass', 'removeClass', 'toggleClass', 'empty', 'remove', 'html', 'prop', 'removeProp');

The sample you provided is not valid PHP and has a few issues:

public scoreTest() {
    ...
}

is not a proper function declaration -- you need to declare functions with the 'function' keyword.

The syntax should rather be:

public function scoreTest() {
    ...
}

Second, wrapping the bigTest() and smallTest() functions in public function() {} does not make them private — you should use the private keyword on both of these individually:

class test () {
    public function newTest(){
        $this->bigTest();
        $this->smallTest();
    }

    private function bigTest(){
        //Big Test Here
    }

    private function smallTest(){
           //Small Test Here
    }

    public function scoreTest(){
      //Scoring code here;
    }
}

Also, it is convention to capitalize class names in class declarations ('Test').

Hope that helps.

            ddlemployee.DataSource = ds.Tables[0];
            ddlemployee.DataTextField = "Employee Name";
            ddlemployee.DataValueField = "RecId";
            ddlemployee.DataBind();
            ddlemployee.Items.Insert(0, "All");

Simply use

$(document).height() // - $('body').offset().top

and / or

$(window).height()

instead of $('body').height();

The best way is to use your code and then store the image in OG tags in the page you are linking to, then Facebook will pick them up.

<meta property="og:title" content="Facebook Open Graph Demo">
<meta property="og:image" content="http://example.com/main-image.png">
<meta property="og:site_name" content="Example Website">
<meta property="og:description" content="Here is a nice description">

You can find documentation to OG tags and how to use them with share buttons here

HTML/JSP Markup:

<form:option 
data-libelle="${compte.libelleCompte}" 
data-raison="${compte.libelleSociale}"   data-rib="${compte.numeroCompte}"                              <c:out value="${compte.libelleCompte} *MAD*"/>
</form:option>

JQUERY CODE: Event: change

var $this = $(this);
var $selectedOption = $this.find('option:selected');
var libelle = $selectedOption.data('libelle');

To have a element libelle.val() or libelle.text()

X * 2 = 1 bit shift left
X / 2 = 1 bit shift right
X * 3 = shift left 1 bit and then add X

Just as important: say you want to log off and you are generating new requests with timers: because session data is renewed with each new bootstrap (maybe you can tell I am talking Drupal, but this could be any site that uses sessions)... I had to go through all my scripts with a search and replace, cause I had a ton of stuff running in different cases: global variables at the top:

var ajReq = [];
var canAj = true;
function abort_all(){
 for(x in ajReq){
    ajReq[x].abort();
    ajReq.splice(x, 1)
 }
 canAj = false;
}
function rmvReq(ranNum){
 var temp = [];
 var i = 0;
 for(x in ajReq){
    if(x == ranNum){
     ajReq[x].abort();
     ajReq.splice(x, 1);
    }
    i++;
 }
}
function randReqIndx(){
 if(!canAj){ return 0; }
 return Math.random()*1000;
}
function getReqIndx(){
 var ranNum;
 if(ajReq.length){
    while(!ranNum){
     ranNum = randReqIndx();
     for(x in ajReq){
    if(x===ranNum){
     ranNum = null;
    }
     }
    }
    return ranMum;
 }
 return randReqIndx();
}
$(document).ready(function(){
 $("a").each(function(){
    if($(this).attr('href').indexOf('/logout')!=-1){          
     $(this).click(function(){
    abort_all();                 
     });
    }
 })
});
// Then in all of my scripts I wrapped my ajax calls... If anyone has a suggestion for a 
    // global way to do this, please post
var reqIndx = getReqIndx();
if(reqIndx!=0){
ajReq[reqIndx] = $.post(ajax, { 'action': 'update_quantities', iids:iidstr, qtys:qtystr },  
function(data){
 //..do stuff
 rmvReq(reqIndx);
 },'json');
}

Another approach I found is to set a delegate for the NavigationController:

navigationController.delegate = self;

and use setNavigationBarHidden in navigationController:willShowViewController:animated:

- (void)navigationController:(UINavigationController *)navigationController 
      willShowViewController:(UIViewController *)viewController 
                    animated:(BOOL)animated 
{   
    // Hide the nav bar if going home.
    BOOL hide = viewController != homeViewController;
    [navigationController setNavigationBarHidden:hide animated:animated];
}

Easy way to customize the behavior for each ViewController all in one place.

Here's a piece of code I put in my scripts that I wan't to run in py2/3-agnostic environment:

# Thank you, python2-3 team, for making such a fantastic mess with
# input/raw_input :-)
real_raw_input = vars(__builtins__).get('raw_input',input)

Now you can use real_raw_input. It's quite expensive but short and readable. Using raw input is usually time expensive (waiting for input), so it's not important.

In theory, you can even assign raw_input instead of real_raw_input but there might be modules that check existence of raw_input and behave accordingly. It's better stay on the safe side.

I know this is old but I'm going to add this here as I've found this question, whilst searching for a solution. The docs allow for a uri: 'Network Image'

https://facebook.github.io/react-native/docs/images#network-images

For me I got images working dynamically with this

<Image source={{uri: image}} />

Set showInLegend to false.

series: [{
            showInLegend: false,
            name: 'Series',
            data: value                
        }]

Open command prompt with admin access and type the following commands there .

a)

tasklist

it displays list of all available services . There you can see the service you want to stop/start/restart . Remember PID value of the service you want to force stop.

b) Now type

taskkill /f /PID [PID value of the service] 

and press enter. On success you will get the message “SUCCESS: The process with PID has been terminated”.

Ex : taskkill /f /PID 5088

This will forcibly kill the frozen service. You can now return to Server Manager and restart the service.

Here's an alternative of jeum's code for an arbitrary number of events:

 var multiClickHandler = function (handlers, delay) {
    var clicks = 0, timeout, delay = delay || 250;
    return function (e) {
      clicks++;
      clearTimeout(timeout);
      timeout = setTimeout(function () {
        if(handlers[clicks]) handlers[clicks](e);
        clicks = 0;
      }, delay);
    };
  }

  cy.on('click', 'node', multiClickHandler({
    1: function(e){console.log('single clicked ', e.cyTarget.id())},
    2: function(e){console.log('double clicked ', e.cyTarget.id())},
    3: function(e){console.log('triple clicked ', e.cyTarget.id())},
    4: function(e){console.log('quadro clicked ', e.cyTarget.id())},
    // ...
  }, 300));

Needed this for a cytoscape.js app.

My two cents: In my case, cacerts was not a folder, but a file, and also it was presents on two paths After discover it, error disappeared after copy the .jks file over that file.

# locate cacerts    
/usr/java/jdk1.8.0_221-amd64/jre/lib/security/cacerts
/usr/java/jre1.8.0_221-amd64/lib/security/cacerts

After backup them, I copy the .jks over.

cp /path_of_jks_file/file.jks /usr/java/jdk1.8.0_221-amd64/jre/lib/security/cacerts
cp /path_of_jks_file/file.jks /usr/java/jre1.8.0_221-amd64/lib/security/cacerts

Note: this basic trick resolves this error on a Genexus project, in spite file.jks is also on the server.xml file of the Tomcat.

Based on docker documentation: https://docs.docker.com/compose/compose-file/#/command

I simply put hostname: <string> in my docker-compose file.

E.g.:

[...]

lb01:
  hostname: at-lb01
  image: at-client-base:v1

[...]

and container lb01 picks up at-lb01 as hostname.

The only solution that worked for me was the one posted by teteArg above. I'm on Spring Boot 1.4.2 w/Hibernate 5. Namely

spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

For additional insight I'm posting the call trace so that its clear what calls Spring is making into Hibernate to setup the naming strategy.

From this article on web.archive.org :

The trick is to use the OnClientClick and UseSubmitBehavior properties of the button control. There are other methods, involving code on the server side to add attributes, but I think the simplicity of doing it this way is much more attractive:

<asp:Button runat="server" ID="BtnSubmit"  OnClientClick="this.disabled = true; this.value = 'Submitting...';"   UseSubmitBehavior="false"  OnClick="BtnSubmit_Click"  Text="Submit Me!" />

OnClientClick allows you to add client side OnClick script. In this case, the JavaScript will disable the button element and change its text value to a progress message. When the postback completes, the newly rendered page will revert the button back its initial state without any additional work.

The one pitfall that comes with disabling a submit button on the client side is that it will cancel the browser’s submit, and thus the postback. Setting the UseSubmitBehavior property to false tells .NET to inject the necessary client script to fire the postback anyway, instead of relying on the browser’s form submission behavior. In this case, the code it injects would be:

__doPostBack('BtnSubmit','')

This is added to the end of our OnClientClick code, giving us this rendered HTML:

<input type="button" name="BtnSubmit"  onclick="this.disabled = true; this.value ='Submitting...';__doPostBack('BtnSubmit','')"  value="Submit Me!" id="BtnSubmit" />

This gives a nice button disable effect and processing text, while the postback completes.

i'd particularly want to add unserialize() to this list. It has had a long history of various vulnerabilities including arbitrary code execution, denial of service and memory information leakage. It should never be called on user-supplied data. Many of these vuls have been fixed in releases over the last dew years, but it still retains a couple of nasty vuls at the current time of writing.

For other information about dodgy php functions/usage look around the Hardened PHP Project and its advisories. Also the recent Month of PHP Security and 2007's Month of PHP Bugs projects

Also note that, by design, unserializing an object will cause the constructor and destructor functions to execute; another reason not to call it on user-supplied data.

By using System.Windows.Forms.Timer class you can achieve what you need.

System.Windows.Forms.Timer t = new System.Windows.Forms.Timer();


t.Interval = 15000; // specify interval time as you want
t.Tick += new EventHandler(timer_Tick);
t.Start();

void timer_Tick(object sender, EventArgs e)
{
      //Call method
}

By using stop() method you can stop timer.

t.Stop();

You can use "RunasDate" to solve this.

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.

var merge = _.merge(arr1, arr2);

Which is the short version of:

var merge = _.chain(arr1).zip(arr2).map(function(item) {
    return _.merge.apply(null, item);
}).value();

Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.

var merge = _.map(arr1, function(item) {
    return _.merge(item, _.find(arr2, { 'member' : item.member }));
});

You can easily convert this to a mixin. See the example below:

_.mixin({_x000D_
  'mergeByKey' : function(arr1, arr2, key) {_x000D_
    var criteria = {};_x000D_
    criteria[key] = null;_x000D_
    return _.map(arr1, function(item) {_x000D_
      criteria[key] = item[key];_x000D_
      return _.merge(item, _.find(arr2, criteria));_x000D_
    });_x000D_

One word answer: MONEY :D

1 GB to store in US-East-1: (Updated at 2016.dec.20)

• Glacier: $0.004/Month (Note: Major price cut in 2016)
• S3: $0.023/Month
• S3-IA (announced in 2015.09): $0.0125/Month (+$0.01/gig retrieval charge)
• EBS: $0.045-0.1/Month (depends on speed - SSD or not) + IOPS costs
• EFS: $0.3/Month

Further storage options, which may be used for temporary storing data while/before processing it:

• SNS
• SQS
• Kinesis stream
• DynamoDB, SimpleDB

The costs above are just samples. There can be differences by region, and it can change at any point. Also there are extra costs for data transfer (out to the internet). However they show a ratio between the prices of the services.

There are a lot more differences between these services:

EFS is:

• Generally Available (out of preview), but may not yet be available in your region
• Network filesystem (that means it may have bigger latency but it can be shared across several instances; even between regions)
• It is expensive compared to EBS (~10x more) but it gives extra features.
• It's a highly available service.
• It's a managed service
• You can attach the EFS storage to an EC2 Instance
• Can be accessed by multiple EC2 instances simultaneously
• Since 2016.dec.20 it's possible to attach your EFS storage directly to on-premise servers via Direct Connect. ()

EBS is:

• A block storage (so you need to format it). This means you are able to choose which type of file system you want.
• As it's a block storage, you can use Raid 1 (or 0 or 10) with multiple block storages
• It is really fast
• It is relatively cheap
• With the new announcements from Amazon, you can store up to 16TB data per storage on SSD-s.
• You can snapshot an EBS (while it's still running) for backup reasons
• But it only exists in a particular region. Although you can migrate it to another region, you cannot just access it across regions (only if you share it via the EC2; but that means you have a file server)
• You need an EC2 instance to attach it to
• New feature (2017.Feb.15): You can now increase volume size, adjust performance, or change the volume type while the volume is in use. You can continue to use your application while the change takes effect.

S3 is:

• An object store (not a file system).
• You can store files and "folders" but can't have locks, permissions etc like you would with a traditional file system
• This means, by default you can't just mount S3 and use it as your webserver
• But it's perfect for storing your images and videos for your website
• Great for short term archiving (e.g. a few weeks). It's good for long term archiving too, but Glacier is more cost efficient.
• Great for storing logs
• You can access the data from every region (extra costs may apply)
• Highly Available, Redundant. Basically data loss is not possible (99.999999999% durability, 99.9 uptime SLA)
• Much cheaper than EBS.
• You can serve the content directly to the internet, you can even have a full (static) website working direct from S3, without an EC2 instance

Glacier is:

• Long term archive storage
• Extremely cheap to store
• Potentially very expensive to retrieve
• Takes up to 4 hours to "read back" your data (so only store items you know you won't need to retrieve for a long time)

As it got mentioned in JDL's comment, there are several interesting aspects in terms of pricing. For example Glacier, S3, EFS allocates the storage for you based on your usage, while at EBS you need to predefine the allocated storage. Which means, you need to over estimate. ( However it's easy to add more storage to your EBS volumes, it requires some engineering, which means you always "overpay" your EBS storage, which makes it even more expensive.)

You can fetch from a remote repository, see the differences and then pull or merge.

This is an example for a remote repository called origin and a branch called master tracking the remote branch origin/master:

git checkout master                                                  
git fetch                                        
git diff origin/master
git rebase origin master

An HTML element like div can have more than one classes. Let say div is assigned two styles using addClass method. If style1 has 3 properties like font-size, weight and color, and style2 has 4 properties like font-size, weight, color and background-color, the resultant effective properties set (style), i think, will have 4 properties i.e. union of all style sets. Common properties, in our case, color,font-size, weight, will have one occuerance with latest values. If div is assigned style1 first and style2 second, the common prpoerties will be overwritten by style2 values.

Further, I have written a post at Using JQuery to Apply,Remove and Manage Styles, I hope it will help you

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

Further information

You may also be interested in reading an answer to a related question.

I find it useful to understand the underlying tools. These are cl.exe (compiler) and link.exe (linker). You need to tell the compiler the signatures of the functions you want to call in the dynamic library (by including the library's header) and you need to tell the linker what the library is called and how to call it (by including the "implib" or import library).

This is roughly the same process gcc uses for linking to dynamic libraries on *nix, only the library object file differs.

Knowing the underlying tools means you can more quickly find the appropriate settings in the IDE and allows you to check that the commandlines generated are correct.

Example

Say A.exe depends B.dll. You need to include B's header in A.cpp (#include "B.h") then compile and link with B.lib:

cl A.cpp /c /EHsc
link A.obj B.lib

The first line generates A.obj, the second generates A.exe. The /c flag tells cl not to link and /EHsc specifies what kind of C++ exception handling the binary should use (there's no default, so you have to specify something).

If you don't specify /c cl will call link for you. You can use the /link flag to specify additional arguments to link and do it all at once if you like:

cl A.cpp /EHsc /link B.lib

If B.lib is not on the INCLUDE path you can give a relative or absolute path to it or add its parent directory to your include path with the /I flag.

If you're calling from cygwin (as I do) replace the forward slashes with dashes.

If you write #pragma comment(lib, "B.lib") in A.cpp you're just telling the compiler to leave a comment in A.obj telling the linker to link to B.lib. It's equivalent to specifying B.lib on the link commandline.

You can do one thing.

1. In the AppSettings.config (create one if doesn't exist), create a key value pair.
2. In the Code pull the value and convert it to Int32 and assign it to command.TimeOut.

like:- In appsettings.config ->

<appSettings>    
   <add key="SqlCommandTimeOut" value="240"/>
</appSettings>

In Code ->

command.CommandTimeout = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

That should do it.

Note:- I faced most of the timeout issues when I used SqlHelper class from microsoft application blocks. If you have it in your code and are facing timeout problems its better you use sqlcommand and set its timeout as described above. For all other scenarios sqlhelper should do fine. If your client is ok with waiting a little longer than what sqlhelper class offers you can go ahead and use the above technique.

example:- Use this -

 SqlCommand cmd = new SqlCommand(completequery);

 cmd.CommandTimeout =  Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

 SqlConnection con = new SqlConnection(sqlConnectionString);
 SqlDataAdapter adapter = new SqlDataAdapter();
 con.Open();
 adapter.SelectCommand = new SqlCommand(completequery, con);
 adapter.Fill(ds);
 con.Close();

Instead of

DataSet ds = new DataSet();
ds = SqlHelper.ExecuteDataset(sqlConnectionString, CommandType.Text, completequery);

Update: Also refer to @Triynko answer below. It is important to check that too.

filtered_list = [list_a[i] for i in range(len(list_a)) if filter[i]]

photo = Image.open('IN.jpg') #your image
photo = photo.convert('RGB')

width = photo.size[0] #define W and H
height = photo.size[1]

for y in range(0, height): #each pixel has coordinates
    row = ""
    for x in range(0, width):

        RGB = photo.getpixel((x,y))
        R,G,B = RGB  #now you can use the RGB value

It's possible to inject instance of ApplicationContext class by using SpringClassRule and SpringMethodRule rules. It might be very handy if you would like to use another non-Spring runners. Here's an example:

@ContextConfiguration(classes = BeanConfiguration.class)
public static class SpringRuleUsage {

    @ClassRule
    public static final SpringClassRule springClassRule = new SpringClassRule();

    @Rule
    public final SpringMethodRule springMethodRule = new SpringMethodRule();

    @Autowired
    private ApplicationContext context;

    @Test
    public void shouldInjectContext() {
    }
}

configure your php.ini like this

SMTP = smtp.gmail.com

[mail function]
; XAMPP: Comment out this if you want to work with an SMTP Server like Mercury

; SMTP = smtp.gmail.com

; smtp_port = 465

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = postmaster@localhost

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.

For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

There is one big reason to use else - style and readability. It's generally a good idea to keep code that can cause exceptions near the code that deals with them. For example, compare these:

try:
    from EasyDialogs import AskPassword
    # 20 other lines
    getpass = AskPassword
except ImportError:
    getpass = default_getpass

and

try:
    from EasyDialogs import AskPassword
except ImportError:
    getpass = default_getpass
else:
    # 20 other lines
    getpass = AskPassword

The second one is good when the except can't return early, or re-throw the exception. If possible, I would have written:

try:
    from EasyDialogs import AskPassword
except ImportError:
    getpass = default_getpass
    return False  # or throw Exception('something more descriptive')

# 20 other lines
getpass = AskPassword

Note: Answer copied from recently-posted duplicate here, hence all this "AskPassword" stuff.

An alternative to System.Diagnostics.StackTrace is to use System.Environment.StackTrace which returns a string-representation of the stacktrace.

Another useful option is to use the $CALLER and $CALLSTACK debugging variables in Visual Studio since this can be enabled run-time without rebuilding the application.

This seemed to work for me:

LocationManager locMan = (LocationManager) activity.getSystemService(activity.LOCATION_SERVICE);
long networkTS = locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER).getTime();

Working on Android 2.2 API (Level 8)

You need to set the binding context of the ToolStripComboBox.ComboBox.

Here is a slightly modified version of the code that I have just recreated using Visual Studio. The menu item combo box is called toolStripComboBox1 in my case. Note the last line of code to set the binding context.

I noticed that if the combo is in the visible are of the toolstrip, the binding works without this but not when it is in a drop-down. Do you get the same problem?

If you can't get this working, drop me a line via my contact page and I will send you the project. You won't be able to load it using SharpDevelop but will with C# Express.

var languages = new string[2];
languages[0] = "English";
languages[1] = "German";

DataSet myDataSet = new DataSet();

// --- Preparation
DataTable lTable = new DataTable("Lang");
DataColumn lName = new DataColumn("Language", typeof(string));
lTable.Columns.Add(lName);

for (int i = 0; i < languages.Length; i++)
{
    DataRow lLang = lTable.NewRow();
    lLang["Language"] = languages[i];
    lTable.Rows.Add(lLang);
}
myDataSet.Tables.Add(lTable);

toolStripComboBox1.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView;
toolStripComboBox1.ComboBox.DisplayMember = "Language";

toolStripComboBox1.ComboBox.BindingContext = this.BindingContext;

An example might help a little here. If I have an instance model of class Model with attributes name and state I can observe those attributes with:

let options = NSKeyValueObservingOptions([.New, .Old, .Initial, .Prior])

model.addObserver(self, forKeyPath: "name", options: options, context: nil)
model.addObserver(self, forKeyPath: "state", options: options, context: nil)

Changes to these properties will trigger a call to:

override func observeValueForKeyPath(keyPath: String!,
    ofObject object: AnyObject!,
    change: NSDictionary!,
    context: CMutableVoidPointer) {

        println("CHANGE OBSERVED: \(change)")
}

I used this one document.querySelector('ElementClass').innerText = 'newtext';

Appears to work with span, texts within classes/buttons

The solutions here work fine when only one element is to be managed. If there are multiple elements, however, the problem is much more complicated. Tricks with e.stopPropagation() and all the others will not work.

I came up with a solution, and maybe it is not so easy, but it's better than nothing. Have a look:

$view.on("click", function(e) {

    if(model.isActivated()) return;

        var watchUnclick = function() {
            rootView.one("mouseleave", function() {
                $(document).one("click", function() {
                    model.deactivate();
                });
                rootView.one("mouseenter", function() {
                    watchUnclick();
                });
            });
        };
        watchUnclick();
        model.activate();
    });

For having a trasition effect like a highlighter just to highlight the text and fade off the bg color, we used the following:

.field-error {_x000D_
    color: #f44336;_x000D_
    padding: 2px 5px;_x000D_
    position: absolute;_x000D_

<div class="field-error highlighter">File name already exists.</div>

I had such problem for windows. And I decided it so: startApp.cmd:

@set JAVA_HOME=C:\jdk160_24
@set PATH=%JAVA_HOME%/bin;%PATH%
@cd /D C:\app\

@start /b C:\WINDOWS\system32\cscript.exe 
C:\app\start.js

and saved it cmd file in dir C:\scripts next file is runApp.bat:

C:\scripts\startApp.cmd

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

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

I had a similar problem. It turned out, I was including an old header file of the same name from an old folder. I deleted the old file changed the #include directive to point to my new file and all was good.

An alternative could be to use the new JSON extension for SQLite. I've only just come across this myself: https://www.sqlite.org/json1.html This would allow you to perform a certain level of querying the stored JSON. If you used VARCHAR or TEXT to store a JSON string you would have no ability to query it. This is a great article showing its usage (in python) http://charlesleifer.com/blog/using-the-sqlite-json1-and-fts5-extensions-with-python/

I use LuaSocket to get more precision.

require "socket"
print("Milliseconds: " .. socket.gettime()*1000)

This adds a dependency of course, but works fine for personal use (in benchmarking scripts for example).

An update on @kalu's answer, which uses the latest pandas:

def find_duplicated_columns(df):
    dupes = []

    columns = df.columns

    for i in range(len(columns)):
        col1 = df.iloc[:, i]
        for j in range(i + 1, len(columns)):
            col2 = df.iloc[:, j]
            # break early if dtypes aren't the same (helps deal with
            # categorical dtypes)
            if col1.dtype is not col2.dtype:
                break
            # otherwise compare values
            if col1.equals(col2):
                dupes.append(columns[i])
                break

    return dupes

When you say "is there an easier way to... trust this cert", that's exactly what you're doing by adding the cert to your Java trust store. And this is very, very easy to do, and there's nothing you need to do within your client app to get that trust store recognized or utilized.

On your client machine, find where your cacerts file is (that's your default Java trust store, and is, by default, located at <java-home>/lib/security/certs/cacerts.

Then, type the following:

keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to cacerts>

That will import the cert into your trust store, and after this, your client app will be able to connect to your Grizzly HTTPS server without issue.

If you don't want to import the cert into your default trust store -- i.e., you just want it to be available to this one client app, but not to anything else you run on your JVM on that machine -- then you can create a new trust store just for your app. Instead of passing keytool the path to the existing, default cacerts file, pass keytool the path to your new trust store file:

keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to new trust store>

You'll be asked to set and verify a new password for the trust store file. Then, when you start your client app, start it with the following parameters:

java -Djavax.net.ssl.trustStore=<path to new trust store> -Djavax.net.ssl.trustStorePassword=<trust store password>

Easy cheesy, really.

Based on all that people had to say here on the answers, its just a combination of keydown(not keyup) + preventDefault() + insert a tab character at the caret. Something like:

var keyCode = e.keyCode || e.which;
if (keyCode == 9) {
   e.preventDefault();
   insertAtCaret('txt', '\t')
}

The earlier answer had a working jsfiddle but it used an alert() on keydown. If you remove this alert, then it didnt work. I ve just added a function to insert a tab at the current cursor position in the textarea.

Here s a working jsfiddle for the same: http://jsfiddle.net/nsHGZ/

You can also remove files from the repository based on your .gitignore without deleting them from the local file system :

git rm --cached `git ls-files -i -X .gitignore`

Or, alternatively, on Windows Powershell:

git rm --cached $(git ls-files -i -X .gitignore)

Use the "Edit top 200" option, then click on "Show SQL panel", modify your query with your WHERE clause, and execute the query. You'll be able to edit the results.

If you want a "rotating" progress bar, why not set the progress bar style to "Marquee" and using a BackgroundWorker to keep the UI responsive? You won't achieve a rotating progress bar easier than using the "Marquee" - style...

1. check for __init__.py file in src folder
2. add the src folder as a source root
3. Then make sure to add add sources to your PYTHONPATH (see above)
4. in PyCharm menu select: File --> Invalidate Caches / Restart

You can always use strtotime to minus the number of days from the current date:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', date('Y-m-d', strtotime("-30 days"))
           ->get();

You could write your own GridWithMargin class, inherited from Grid, and override the ArrangeOverride method to apply the margins

An alternative is to create a helper file where you have a const object with functions as properties of the object. This way you only export and import one object.

helpers.js

const helpers = {
    helper1: function(){

    },
    helper2: function(param1){

    },
    helper3: function(param1, param2){

    }
}

export default helpers;

Then, import like this:

import helpers from './helpers';

and use like this:

helpers.helper1();
helpers.helper2('value1');
helpers.helper3('value1', 'value2');

My random guess is: TV uses x264 codec which has a commercial license (otherwise TeamViewer would have to release their source code). At some point (more than 5 years ago), I recall main developer of x264 wrote an article about improvements he made for low delay encoding (if you delay by a few frames encoders can compress better), plus he mentioned some other improvements that were relevant for TeamViewer-like use. In that post he mentioned playing quake over video stream with no noticeable issues. Back then I was kind of sure who was the sponsor of these improvements, as TeamViewer was pretty much the only option at that time. x264 is an open source implementation of H264 video codec, and it's insanely good implementation, it's the best one. At the same time it's extremely well optimized. Most likely due to extremely good implementation of x264 you get much better results with TV at lower CPU load. AnyDesk and Chrome Remote Desk use libvpx, which isn't as good as x264 (optimization and video quality wise).

However, I don't think TeamView can beat microsoft's RDP. To me it's the best, however it works between windows PCs or from Mac to Windows only. TV works even from mobiles.

Update: article was written in January 2010, so that work was done roughly 10 years ago. Also, I made a mistake: he played call of duty, not quake. When you posted your question, if my guess is correct, TeamViewer had been using that work for 3 years. Read that blog post from web archive: x264: the best low-latency video streaming platform in the world. When I read the article back in 2010, I was sure that the "startup–which has requested not to be named" that the author mentions was TeamViewer.

For MSSQL, there are two ways:(Consider you have a 'users' table,below both examples are using this table for example)

1) In case, you need to insert different values in users table. Then you can write statement like:

    INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe'),
(3, 'Linda', 'Mitchell'),
(4, 'Jillian', 'Carson'),
(5, 'Garrett', 'Vargas');

2) Another case, if you need to insert same value for all rows(for example, 10 rows you need to insert here). Then you can use below sample statement:

    INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe')
GO 10

Hope this helps.

When calling a function that is declared with throws in Swift, you must annotate the function call site with try or try!. For example, given a throwing function:

func willOnlyThrowIfTrue(value: Bool) throws {
  if value { throw someError }
}

this function can be called like:

func foo(value: Bool) throws {
  try willOnlyThrowIfTrue(value)
}

Here we annotate the call with try, which calls out to the reader that this function may throw an exception, and any following lines of code might not be executed. We also have to annotate this function with throws, because this function could throw an exception (i.e., when willOnlyThrowIfTrue() throws, then foo will automatically rethrow the exception upwards.

If you want to call a function that is declared as possibly throwing, but which you know will not throw in your case because you're giving it correct input, you can use try!.

func bar() {
  try! willOnlyThrowIfTrue(false)
}

This way, when you guarantee that code won't throw, you don't have to put in extra boilerplate code to disable exception propagation.

try! is enforced at runtime: if you use try! and the function does end up throwing, then your program's execution will be terminated with a runtime error.

Most exception handling code should look like the above: either you simply propagate exceptions upward when they occur, or you set up conditions such that otherwise possible exceptions are ruled out. Any clean up of other resources in your code should occur via object destruction (i.e. deinit()), or sometimes via defered code.

func baz(value: Bool) throws {

  var filePath = NSBundle.mainBundle().pathForResource("theFile", ofType:"txt")
  var data = NSData(contentsOfFile:filePath)

  try willOnlyThrowIfTrue(value)

  // data and filePath automatically cleaned up, even when an exception occurs.
}

If for whatever reason you have clean up code that needs to run but isn't in a deinit() function, you can use defer.

func qux(value: Bool) throws {
  defer {
    print("this code runs when the function exits, even when it exits by an exception")
  }

  try willOnlyThrowIfTrue(value)
}

Most code that deals with exceptions simply has them propagate upward to callers, doing cleanup on the way via deinit() or defer. This is because most code doesn't know what to do with errors; it knows what went wrong, but it doesn't have enough information about what some higher level code is trying to do in order to know what to do about the error. It doesn't know if presenting a dialog to the user is appropriate, or if it should retry, or if something else is appropriate.

Higher level code, however, should know exactly what to do in the event of any error. So exceptions allow specific errors to bubble up from where they initially occur to the where they can be handled.

Handling exceptions is done via catch statements.

func quux(value: Bool) {
  do {
    try willOnlyThrowIfTrue(value)
  } catch {
    // handle error
  }
}

You can have multiple catch statements, each catching a different kind of exception.

  do {
    try someFunctionThatThowsDifferentExceptions()
  } catch MyErrorType.errorA {
    // handle errorA
  } catch MyErrorType.errorB {
    // handle errorB
  } catch {
    // handle other errors
  }

For more details on best practices with exceptions, see http://exceptionsafecode.com/. It's specifically aimed at C++, but after examining the Swift exception model, I believe the basics apply to Swift as well.

For details on the Swift syntax and error handling model, see the book The Swift Programming Language (Swift 2 Prerelease).

older versions xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

This changed again in Angular2 RC.5

I will update the example below but it's the last day before vacation.

This Plunker example demonstrates how to dynamically create components in RC.5

Update - use ViewContainerRef.createComponent()

Because DynamicComponentLoader is deprecated, the approach needs to be update again.

@Component({
  selector: 'dcl-wrapper',
  template: `<div #target></div>`
})
export class DclWrapper {
  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private resolver: ComponentResolver) {}

  updateComponent() {
    if(!this.isViewInitialized) {
      return;
    }
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
   this.resolver.resolveComponent(this.type).then((factory:ComponentFactory<any>) => {
      this.cmpRef = this.target.createComponent(factory)
      // to access the created instance use
      // this.compRef.instance.someProperty = 'someValue';
      // this.compRef.instance.someOutput.subscribe(val => doSomething());
    });
  }

  ngOnChanges() {
    this.updateComponent();
  }

  ngAfterViewInit() {
    this.isViewInitialized = true;
    this.updateComponent();  
  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }    
  }
}

Plunker example RC.4
Plunker example beta.17

Update - use loadNextToLocation

export class DclWrapper {
  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private dcl:DynamicComponentLoader) {}

  updateComponent() {
    // should be executed every time `type` changes but not before `ngAfterViewInit()` was called 
    // to have `target` initialized
    if(!this.isViewInitialized) {
      return;
    }
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
    this.dcl.loadNextToLocation(this.type, this.target).then((cmpRef) => {
      this.cmpRef = cmpRef;
    });
  }

  ngOnChanges() {
    this.updateComponent();
  }

  ngAfterViewInit() {
    this.isViewInitialized = true;
    this.updateComponent();  
  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }    
  }
}

Plunker example beta.17

original

Not entirely sure from your question what your requirements are but I think this should do what you want.

The Tabs component gets an array of types passed and it creates "tabs" for each item in the array.

@Component({
  selector: 'dcl-wrapper',
  template: `<div #target></div>`
})
export class DclWrapper {
  constructor(private elRef:ElementRef, private dcl:DynamicComponentLoader) {}
  @Input() type;

  ngOnChanges() {
    if(this.cmpRef) {
      this.cmpRef.dispose();
    }
    this.dcl.loadIntoLocation(this.type, this.elRef, 'target').then((cmpRef) => {
      this.cmpRef = cmpRef;
    });
  }
}

@Component({
  selector: 'c1',
  template: `<h2>c1</h2>`

})
export class C1 {
}

@Component({
  selector: 'c2',
  template: `<h2>c2</h2>`

})
export class C2 {
}

@Component({
  selector: 'c3',
  template: `<h2>c3</h2>`

})
export class C3 {
}

@Component({
  selector: 'my-tabs',
  directives: [DclWrapper],
  template: `
  <h2>Tabs</h2>
  <div *ngFor="let tab of tabs">
    <dcl-wrapper [type]="tab"></dcl-wrapper>
  </div>
`
})
export class Tabs {
  @Input() tabs;
}


@Component({
  selector: 'my-app',
  directives: [Tabs]
  template: `
  <h2>Hello {{name}}</h2>
  <my-tabs [tabs]="types"></my-tabs>
`
})
export class App {
  types = [C3, C1, C2, C3, C3, C1, C1];
}

Plunker example beta.15 (not based on your Plunker)

There is also a way to pass data along that can be passed to the dynamically created component like (someData would need to be passed like type)

    this.dcl.loadIntoLocation(this.type, this.elRef, 'target').then((cmpRef) => {
  cmpRef.instance.someProperty = someData;
  this.cmpRef = cmpRef;
});

There is also some support to use dependency injection with shared services.

For more details see https://angular.io/docs/ts/latest/cookbook/dynamic-component-loader.html

Here's another approach.

git checkout {SOURCE_BRANCH}               # switch to Source branch.
git checkout {COMMIT_HASH}                 # go back to the desired commit.
git checkout -b {temp_branch}              # create a new temporary branch from {COMMIT_HASH} snapshot.
git checkout {TARGET_BRANCH}               # switch to Target branch.
git merge {temp_branch}                    # merge code to your Target branch.
git branch -d {temp_branch}                # delete the temp branch.

In my experience, this example has been the best solution for uploading a resized picture: https://zocada.com/compress-resize-images-javascript-browser/

It uses the HTML5 Canvas feature.

The code is as 'simple' as this:

compress(e) {
    const fileName = e.target.files[0].name;
    const reader = new FileReader();
    reader.readAsDataURL(e.target.files[0]);
    reader.onload = event => {
        const img = new Image();
        img.src = event.target.result;
        img.onload = () => {
                const elem = document.createElement('canvas');
                const width = Math.min(800, img.width);
                const scaleFactor = width / img.width;
                elem.width = width;
                elem.height = img.height * scaleFactor;

                const ctx = elem.getContext('2d');
                // img.width and img.height will contain the original dimensions
                ctx.drawImage(img, 0, 0, width, img.height * scaleFactor);
                ctx.canvas.toBlob((blob) => {
                    const file = new File([blob], fileName, {
                        type: 'image/jpeg',
                        lastModified: Date.now()
                    });
                }, 'image/jpeg', 1);
            },
            reader.onerror = error => console.log(error);
    };
}

There are two downsides with this solution.

The first one is related with the image rotation, due to ignoring EXIF data. I couldn't tackle this issue, and wasn't so important in my use case, but will be glad to hear any feedback.

The second downside is the lack of support foe IE/Edge (not the Chrome based version though), and I won't put any time on that.

Let's break down your examples one by one.

@media (max-width:632px)

This one is saying for a window with a max-width of 632px that you want to apply these styles. At that size you would be talking about anything smaller than a desktop screen in most cases.

@media screen and (max-width:632px)

This one is saying for a device with a screen and a window with max-width of 632px apply the style. This is almost identical to the above except you are specifying screen as opposed to the other available media types the most common other one being print.

@media only screen and (max-width:632px)

Here is a quote straight from W3C to explain this one.

The keyword ‘only’ can also be used to hide style sheets from older user agents. User agents must process media queries starting with ‘only’ as if the ‘only’ keyword was not present.

As there is no such media type as "only", the style sheet should be ignored by older browsers.

Here's the link to that quote that is shown in example 9 on that page.

Hopefully this sheds some light on media queries.

EDIT:

Be sure to check out @hybrids excellent answer on how the only keyword is really handled.

The best solution I could find at present time to open a window maximized is (Internet Explorer 11, Chrome 49, Firefox 45):

  var popup = window.open("your_url", "popup", "fullscreen");
  if (popup.outerWidth < screen.availWidth || popup.outerHeight < screen.availHeight)
  {
    popup.moveTo(0,0);
    popup.resizeTo(screen.availWidth, screen.availHeight);
  }

see https://jsfiddle.net/8xwocrp6/7/

Note 1: It does not work on Edge (13.1058686). Not sure whether it's a bug or if it's as designed (I've filled a bug report, we'll see what they have to say about it). Here is a workaround:

if (navigator.userAgent.match(/Edge\/\d+/g))
{
    return window.open("your_url", "popup", "width=" + screen.width + ",height=" + screen.height);
}

Note 2: moveTo or resizeTo will not work (Access denied) if the window you are opening is on another domain.

shell_exec returns all of the output stream as a string. exec returns the last line of the output by default, but can provide all output as an array specifed as the second parameter.

See

• http://php.net/manual/en/function.shell-exec.php
• http://php.net/manual/en/function.exec.php

As the question is based in hypothetical data here is a good exemple returning a generic that extends Comparable interface.

public class MaximumTest {
    // find the max value using Comparable interface
    public static <T extends Comparable<T>> T maximum(T x, T y, T z) {
        T max = x; // assume that x is initially the largest

        if (y.compareTo(max) > 0){
            max = y; // y is the large now
        }
        if (z.compareTo(max) > 0){
            max = z; // z is the large now
        }
        return max; // returns the maximum value
    }    


    //testing with an ordinary main method
    public static void main(String args[]) {
        System.out.printf("Maximum of %d, %d and %d is %d\n\n", 3, 4, 5, maximum(3, 4, 5));
        System.out.printf("Maximum of %.1f, %.1f and %.1f is %.1f\n\n", 6.6, 8.8, 7.7, maximum(6.6, 8.8, 7.7));
        System.out.printf("Maximum of %s, %s and %s is %s\n", "strawberry", "apple", "orange",
                maximum("strawberry", "apple", "orange"));
    }
}

You need to define the output parameter as an output parameter in the code with the ParameterDirection.Output enumeration. There are numerous examples of this out there, but here's one on MSDN.

Does the JS library define/initialize any well known variable on the window?

If so you could wait for the variable to appear. You can use

((JavascriptExecutor)driver).executeScript(String script, Object... args)

to test for this condition (something like: window.SomeClass && window.SomeClass.variable != null) and return a boolean true / false.

Wrap this in a WebDriverWait, and wait until the script returns true.

For Ubuntu 18.04.4 LTS I just followed the official instructions: https://classic.yarnpkg.com/en/docs/install#debian-stable

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sudo apt update && sudo apt install yarn

No need to do:

sudo apt remove cmdtest

That is only necessary on Ubuntu 17.04.* I think.

I hope it helps!

The max length of a string on my machine is 1,073,741,791.

You see, Strings aren't limited by integer as is commonly believed.

Memory restrictions aside, Strings cannot have more than 2³⁰ (1,073,741,824) characters, since a 2GB limit is imposed by the Microsoft CLR (Common Language Runtime). 33 more than my computer allowed.

Now, here's something you're welcome to try yourself.

Create a new C# console app in Visual Studio and then copy/paste the main method here:

static void Main(string[] args)
{
    Console.WriteLine("String test, by Nicholas John Joseph Taylor");

    Console.WriteLine("\nTheoretically, C# should support a string of int.MaxValue, but we run out of memory before then.");

    Console.WriteLine("\nThis is a quickish test to narrow down results to find the max supported length of a string.");

    Console.WriteLine("\nThe test starts ...now:\n");

    int Length = 0;

    string s = "";

    int Increment = 1000000000; // We know that s string with the length of 1000000000 causes an out of memory exception.

    LoopPoint:

    // Make a string appendage the length of the value of Increment

    StringBuilder StringAppendage = new StringBuilder();

    for (int CharacterPosition = 0; CharacterPosition < Increment; CharacterPosition++)
    {
        StringAppendage.Append("0");

    }

    // Repeatedly append string appendage until an out of memory exception is thrown.

    try
    {
        if (Increment > 0)
            while (Length < int.MaxValue)
            {
                Length += Increment;

                s += StringAppendage.ToString(); // Append string appendage the length of the value of Increment

                Console.WriteLine("s.Length = " + s.Length + " at " + DateTime.Now.ToString("dd/MM/yyyy HH:mm"));

            }

    }
    catch (OutOfMemoryException ex) // Note: Any other exception will crash the program.
    {
        Console.WriteLine("\n" + ex.Message + " at " + DateTime.Now.ToString("dd/MM/yyyy HH:mm") + ".");

        Length -= Increment;

        Increment /= 10;

        Console.WriteLine("After decimation, the value of Increment is " + Increment + ".");

    }
    catch (Exception ex2)
    {
        Console.WriteLine("\n" + ex2.Message + " at " + DateTime.Now.ToString("dd/MM/yyyy HH:mm") + ".");

        Console.WriteLine("Press a key to continue...");

        Console.ReadKey();

    }

    if (Increment > 0)
    {
        goto LoopPoint;

    }

    Console.WriteLine("Test complete.");

    Console.WriteLine("\nThe max length of a string is " + s.Length + ".");

    Console.WriteLine("\nPress any key to continue.");

    Console.ReadKey();

}

My results were as follows:

String test, by Nicholas John Joseph Taylor

Theoretically, C# should support a string of int.MaxValue, but we run out of memory before then.

This is a quickish test to narrow down results to find the max supported length of a string.

The test starts ...now:

I'd appreciate it very much if people could post their results as a comment below.

It will be interesting to learn if people get the same or different results.

You might also find it useful to know generally what these data types are used for:

• :string - is for small data types such as a title. (Should you choose string or text?)
• :text - is for longer pieces of textual data, such as a paragraph of information
• :binary - is for storing data such as images, audio, or movies.
• :boolean - is for storing true or false values.
• :date - store only the date
• :datetime - store the date and time into a column.
• :time - is for time only
• :timestamp - for storing date and time into a column.(What's the difference between datetime and timestamp?)
• :decimal - is for decimals (example of how to use decimals).
• :float - is for decimals. (What's the difference between decimal and float?)
• :integer - is for whole numbers.
• :primary_key - unique key that can uniquely identify each row in a table

There's also references used to create associations. But, I'm not sure this is an actual data type.

New Rails 4 datatypes available in PostgreSQL:

• :hstore - storing key/value pairs within a single value (learn more about this new data type)
• :array - an arrangement of numbers or strings in a particular row (learn more about it and see examples)
• :cidr_address - used for IPv4 or IPv6 host addresses
• :inet_address - used for IPv4 or IPv6 host addresses, same as cidr_address but it also accepts values with nonzero bits to the right of the netmask
• :mac_address - used for MAC host addresses

Learn more about the address datatypes here and here.

Note that I made use of ES6's template strings to compose the regex expression.

I hope that you will find helpfull the following trick.

You can bind both the events

combobox.SelectionChanged += OnSelectionChanged;
combobox.DropDownOpened += OnDropDownOpened;

And force selected item to null inside the OnDropDownOpened

private void OnDropDownOpened(object sender, EventArgs e)
{
    combobox.SelectedItem = null;
}

And do what you need with the item inside the OnSelectionChanged. The OnSelectionChanged will be raised every time you will open the combobox, but you can check if SelectedItem is null inside the method and skip the command

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        if (combobox.SelectedItem != null)
        {
           //Do something with the selected item
        }
    }

This might help:

<input type="number" step="1" pattern="\d+" />

step is for convenience (and could be set to another integer), but pattern does some actual enforcing.

Note that since pattern matches the whole expression, it wasn't necessary to express it as ^\d+$.

Even with this outwardly tight regular expression, Chrome and Firefox's implementations, interestingly allow for e here (presumably for scientific notation) as well as - for negative numbers, and Chrome also allows for . whereas Firefox is tighter in rejecting unless the . is followed by 0's only. (Firefox marks the field as red upon the input losing focus whereas Chrome doesn't let you input disallowed values in the first place.)

Since, as observed by others, one should always validate on the server (or on the client too, if using the value locally on the client or wishing to prevent the user from a roundtrip to the server).

Use checked="checked" attribute if you want your checkbox to be checked.

Take a look at the Collections.sort(List<T> list).

You can simply remove the first element, sort the list and then add it back again.

In PHPStorm, it's a bit easier: you can just search for NPM in settings or:

File > Settings > Language & Frameworks > Node.js and NPM

Then click the enable button (apparently in new versions, it is called "Coding assistance for Node").

An easy to understand and simple solution.

// Save today's date.
var today = DateTime.Today;

// Calculate the age.
var age = today.Year - birthdate.Year;

// Go back to the year in which the person was born in case of a leap year
if (birthdate.Date > today.AddYears(-age)) age--;

However, this assumes you are looking for the western idea of the age and not using East Asian reckoning.

The Instagram API requires user authentication through OAuth to access the recent media endpoint for a user. There doesn't appear to be any other way right now to get all media for a user.

This is an old question, but I use the following class to do the job. It's based on Scott Dorman's blog:

public class NameValueCollectionConfigurationSection : ConfigurationSection
{
    private const string COLLECTION_PROP_NAME = "";

    public IEnumerable<KeyValuePair<string, string>> GetNameValueItems()
    {
        foreach ( string key in this.ConfigurationCollection.AllKeys )
        {
            NameValueConfigurationElement confElement = this.ConfigurationCollection[key];
            yield return new KeyValuePair<string, string>
                (confElement.Name, confElement.Value);
        }
    }

    [ConfigurationProperty(COLLECTION_PROP_NAME, IsDefaultCollection = true)]
    protected NameValueConfigurationCollection ConfCollection
    {
        get
        {
            return (NameValueConfigurationCollection) base[COLLECTION_PROP_NAME];
        }
    }

The usage is straightforward:

Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
NameValueCollectionConfigurationSection config = 
    (NameValueCollectionConfigurationSection) configuration.GetSection("MyParams");

NameValueCollection myParamsCollection = new NameValueCollection();
config.GetNameValueItems().ToList().ForEach(kvp => myParamsCollection.Add(kvp));

You can use the iterator remove() function to remove the object from underlying collection object. But in this case you can remove the same object and not any other object from the list.

Make a batch file "Pc.bat" as, typeperf -sc 1 "\mukit\processor(_Total)\%% Processor Time"

You can use the class MProcess,

/*
 *Md. Mukit Hasan
 *CSE-JU,35
 **/
import java.io.*;

public class MProcessor {
public MProcessor() {
String s;
try {
Process ps = Runtime.getRuntime().exec("Pc.bat");
BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
while((s = br.readLine()) != null) {
System.out.println(s);
}
}
catch( Exception ex ) {
System.out.println(ex.toString());
}
}

}

Then after some string manipulation, you get the CPU use. You can use the same process for other tasks.

After trying everything here twice in different order, I reinstalled everything and before doing cordova platform add android I went to templates/gradle and ran gradlew.bat. After this completed, I was able to add the android platform without any problem.

points 1, 2, and 3 being reasonably well covered:

You can see collation settings for each table like the following code:

SELECT t.name TableName, c.name ColumnName, collation_name  
FROM sys.columns c  
INNER JOIN sys.tables t on c.object_id = t.object_id where t.name = 'name of table';

Use raw keyword, http://twig.sensiolabs.org/doc/api.html#escaper-extension

Needed this answer myself and from the link provided by David Moye, decided on this and thought it might be of use to others with the same question:

CREATE PROCEDURE ...
AS
BEGIN
  BEGIN TRANSACTION

  -- lock table "a" till end of transaction
  SELECT ...
  FROM a
  WITH (TABLOCK, HOLDLOCK)
  WHERE ...

  -- do some other stuff (including inserting/updating table "a")



  -- release lock
  COMMIT TRANSACTION
END

On Windows 10 - you should add two different arguments.

(1) Add the new variable and value as - HADOOP_HOME and path (i.e. c:\Hadoop) under System Variables.

(2) Add/append new entry to the "Path" variable as "C:\Hadoop\bin".

The above worked for me.

TL;DR

%matplotlib inline - Displays output inline

IPython kernel has the ability to display plots by executing code. The IPython kernel is designed to work seamlessly with the matplotlib plotting library to provide this functionality.

%matplotlib is a magic command which performs the necessary behind-the-scenes setup for IPython to work correctly hand-in-hand with matplotlib; it does not execute any Python import commands, that is, no names are added to the namespace.

Display output in separate window

%matplotlib

Display output inline

(available only for the Jupyter Notebook and the Jupyter QtConsole)

%matplotlib inline

Display with interactive backends

(valid values 'GTK3Agg', 'GTK3Cairo', 'MacOSX', 'nbAgg', 'Qt4Agg', 'Qt4Cairo', 'Qt5Agg', 'Qt5Cairo', 'TkAgg', 'TkCairo', 'WebAgg', 'WX', 'WXAgg', 'WXCairo', 'agg', 'cairo', 'pdf', 'pgf', 'ps', 'svg', 'template')

%matplotlib gtk

Example - GTK3Agg - An Agg rendering to a GTK 3.x canvas (requires PyGObject and pycairo or cairocffi).

More details about matplotlib interactive backends: here

Starting with IPython 5.0 and matplotlib 2.0 you can avoid the use of IPython’s specific magic and use matplotlib.pyplot.ion()/matplotlib.pyplot.ioff() which have the advantages of working outside of IPython as well.

what led me to this page is that I set within a page then the inside of an included page I did the increment

and here is the problem

so to solve such a problem, simply use scope="request" when you declare the variable or the increment

//when you set the variale add scope="request"
<c:set var="nFilters" value="${0}" scope="request"/>
//the increment, it can be happened inside an included page
<c:set var="nFilters" value="${nFilters + 1}"  scope="request" />

hope this saves your time

cursor = conn.cursor()
qry = """ SELECT details FROM test_csvfile """

A char consists of a single character and should be specified in single quotes. It can contain an alphabetic, numerical or even special character. below are a few examples:

char a = '4';
char b = '$';
char c = 'B';

A String defines a line can be used which is specified in double quotes. Below are a few examples:

String a = "Hello World";
String b = "1234";
String c = "%%";

if you are on windows, you can add opencv path to OpenCV_DIR yourself. (OpenCV_DIR is in the red region)

the path is like "D:/opencv244/build".

you can find file "OpenCVConfig.cmake" under the path.

I had a similiar problem and the only solution was rebooting vagrant which I use as dev enviroment. Beside that, not a single artisan and composer command didn't help.

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

Use YAML files for properties, this supports properties as an array.

Quick glance about YAML:

A superset of JSON, it can do everything JSON can + more

1. Simple to read
2. Long properties into multiline values
3. Supports comments
4. Properties as Array
5. YAML Validation

For Ubuntu users, an answer can be found here. I also quote it:

The most probable cause, is that you have not installed the appropriate dependencies. Your Ubuntu system has to have some packages installed regarding conversion of LaTeX and XeTeX files, in order to save your notebook as PDF. You can install them by:

sudo apt-get install texlive texlive-xetex texlive-generic-extra texlive-generic-recommended pandoc

Also, nbconvert is another dependency that is usually automatically installed with jupyter. But you can install it just to be sure, while having your virtual environment activated:

pip install -U nbconvert

If you want to do it without any extra includes:

vector<IComponent*> myComponents; //assume it has items in it already.
void RemoveComponent(IComponent* componentToRemove)
{
    IComponent* juggler;

    if (componentToRemove != NULL)
    {
        for (int currComponentIndex = 0; currComponentIndex < myComponents.size(); currComponentIndex++)
        {
            if (componentToRemove == myComponents[currComponentIndex])
            {
                //Since we don't care about order, swap with the last element, then delete it.
                juggler = myComponents[currComponentIndex];
                myComponents[currComponentIndex] = myComponents[myComponents.size() - 1];
                myComponents[myComponents.size() - 1] = juggler;

                //Remove it from memory and let the vector know too.
                myComponents.pop_back();
                delete juggler;
            }
        }
    }
}

you can set default collation at several levels:

http://dev.mysql.com/doc/refman/5.0/en/charset-syntax.html

1) client 2) server default 3) database default 4) table default 5) column

While you are switching, switch to PDO instead of mysqli, It helps you write database agnositc code and have better features for prepared statements.

http://www.php.net/pdo

Bindparam for PDO: http://se.php.net/manual/en/pdostatement.bindparam.php

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = :value1 && field2 = :value2");
$sth->bindParam(':value1', 'foo');
$sth->bindParam(':value2', 'bar');
$sth->execute();

or:

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = ? && field2 = ?");
$sth->bindParam(1, 'foo');
$sth->bindParam(2, 'bar');
$sth->execute();

or execute with the parameters as an array:

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = :value1 && field2 = :value2");
$sth->execute(array(':value1' => 'foo' , ':value2' => 'bar'));

It will be easier for you if you would like your application to be able to run on different databases in the future.

I also think you should invest some time in using some of the classes from Zend Framwework whilst working with PDO. Check out their Zend_Db and more specifically [Zend_Db_Factory][2]. You do not have to use all of the framework or convert your application to the MVC pattern, but using the framework and reading up on it is time well spent.

I want to know how can I update some field(not all) like method 1 where id = 1

Use @Query, as you did in Method 2.

is too long query in my case because I have many field in my entity

Then have smaller entities. Or, do not update fields individually, but instead have more coarse-grained interactions with the database.

IOW, there is nothing in Room itself that will do what you seek.

UPDATE 2020-09-15: Room now has partial entity support, which can help with this scenario. See this answer for more.

Solutions in accepted answer are being deprecated

#4 Calling prop directly

Enzyme simulate is supposed to be removed in version 4. The main maintainer is suggesting directly invoking prop functions, which is what simulate does internally. One solution is to directly test that invoking those props does the right thing; or you can mock out instance methods, test that the prop functions call them, and unit test the instance methods.

You could call click, for example:

wrapper.find('Button').prop('onClick')() 

Or

wrapper.find('Button').props().onClick()

It is possible get your approximate locate based on your IP address (wireless or fixed).

See for example hostip.info or maxmind which basically provide a mapping from IP address to geographical coordinates. The probably use many kinds of heuristics and datasources. This kind of system has probably enough accuracy to put you in right major city, in most cases.

Google probably uses somewhat similar approach in addition to WiFi tricks.
