If you want to rename all occurrences of some key you can use a regex with the g option. For example:

var json = [{"_id":"1","email":"[email protected]","image":"some_image_url","name":"Name 1"},{"_id":"2","email":"[email protected]","image":"some_image_url","name":"Name 2"}];

str = JSON.stringify(json);

now we have the json in string format in str.

Replace all occurrences of "_id" to "id" using regex with the g option:

str = str.replace(/\"_id\":/g, "\"id\":");

and return to json format:

json = JSON.parse(str);

now we have our json with the wanted key name.

Never too late to post an alternative answer I hope. Here's a snippet of my Find last Cell. I'm primarily interested in speed. On a DB I'm using with around 150,000 rows this function took (average) 0.087 seconds to find solution compared to @Mogsdad elegant JS solution above which takes (average) 0.53 sec on same data. Both arrays were pre-loaded before the function call. It makes use of recursion to do a binary search. For 100,000+ rows you should find it takes no more than 15 to 20 hops to return it's result.

I've left the Log calls in so you can test it in the console first and see its workings.

/* @OnlyCurrentDoc */

function myLastRow() {

var ss=SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var colArray = ss.getRange('A1:A').getDisplayValues();  // Change to relevant column label and put in Cache
var TestRow=ss.getLastRow();
var MaxRow=ss.getMaxRows(); 

Logger.log ('TestRow = %s',TestRow);
Logger.log ('MaxRow = %s',MaxRow);

var FoundRow=FindLastRow(TestRow,MaxRow);

Logger.log ('FoundRow = %s',FoundRow);    

function FindLastRow(v_TestRow,v_MaxRow) {

/* Some housekeeping/error trapping first
* 1) Check that LastRow doesn't = Max Rows. If so then suggest to add a few lines as this
* indicates the LastRow was the end of the sheet.
* 2) Check it's not a new sheet with no data ie, LastRow = 0 and/or cell A1 is empty.
* 3) A return result of 0 = an error otherwise any positive value is a valid result.
*/

 return   !(colArray[0][0]) ? 1                   // if first row is empty then presume it's a new empty sheet
        :!!(colArray[v_TestRow][0]) ? v_TestRow   // if the last row is not empty then column A was the longest
        : v_MaxRow==v_TestRow ? v_TestRow         // if Last=Max then consider adding a line here to extend row count, else
        : searchPair(0,v_TestRow);                // get on an find the last row
}

function searchPair(LowRow,HighRow){

var BinRow = ((LowRow+HighRow)/2)|0;   // force an INT to avoid row ambiguity

Logger.log ('LowRow/HighRow/BinRow = %s/%s/%s',LowRow, HighRow, BinRow);

/*   Check your log. You shoud find that the last row is always found in under 20 hops.
 *   This will be true whether your data rows are 100 or 100,000 long.
 *   The longest element of this script is loading the Cache (ColArray)
 */

 return   (!(colArray[BinRow-1][0]))^(!(colArray[BinRow][0])) ? BinRow
        : (!(colArray[BinRow-1][0]))&(!(colArray[BinRow][0])) ? searchPair(LowRow,BinRow-1)
        : (!!(colArray[BinRow-1][0]))|(!!(colArray[BinRow][0])) ? searchPair(BinRow+1,HighRow)
        : false;   // Error
 }
}

/* The premise for the above logic is that the binary search is looking for a specific pairing, <Text/No text>
 * on adjacent rows.  You said there are no gaps so the pairing <No Text/Text> is not tested as it's irrelevant.
 * If the logic finds <No Text/No Text> then it looks back up the sheet, if it finds <Text/Text> it looks further
 * down the sheet.  I think you'll find this is quite fast, especially on datasets > 100,000 rows.
 */

If you don't want to show the series names in the legend you can disable them by setting showInLegend:false.

example:

series: [{
   showInLegend: false,             
   name: "<b><?php echo $title; ?></b>",
   data: [<?php echo $yaxis; ?>],
}]

You get other options here.

• legend options

• other chart options

I'm positive it would require SMTP authentication credentials as well.

This is one of the method to overcome this issue.

• Just put the prototype in the header files and include the header files in the .cpp files as shown below.

client.cpp

    bool read(int, char*); // Or whatever the name is...

//  ... };

#endif

client.h

bool SocketClient::read(int, char*)
{
    // Implementation  goes here...
}

main.cpp

#include <iostream>
#include <string>

An easier way is to use the material spinner library: https://github.com/jaredrummler/MaterialSpinner

first add to your project:

compile 'com.jaredrummler:material-spinner:1.2.4'

and use like this:

<com.jaredrummler.materialspinner.MaterialSpinner
    android:id="@+id/spinner"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

and java code that you can add items in java so easy:

MaterialSpinner spinner = (MaterialSpinner) findViewById(R.id.spinner);
spinner.setItems("item 1", "item 2", "item 3", "item 4", "item 5");
spinner.setOnItemSelectedListener(new MaterialSpinner.OnItemSelectedListener<String>() {

  @Override public void onItemSelected(MaterialSpinner view, int position, long id, String item) {
    Snackbar.make(view, "Clicked " + item, Snackbar.LENGTH_LONG).show();
  }
});

@Html.TextBoxFor(model => model.IssueDate, new { @class = "form-control", name = "inv_issue_date", id = "inv_issue_date", title = "Select Invoice Issue Date", placeholder = "dd/mm/yyyy", style = "text-align:center;" })

Yes, it's historical. Without it, it creates an old-style class.

If you use type() on an old-style object, you just get "instance". On a new-style object you get its class.

I get this error when my project .net framework version does not match the framework version of the DLL I am linking to. In my case, I was getting:

"The type or namespace name 'UserVoice' could not be found (are you missing a using directive or an assembly reference?).

UserVoice was .Net 4.0, and my project properties were set to ".Net 4.0 Client Profile". Changing to .Net 4.0 on the project cleared the error. I hope this helps someone.

To ensure easy and correct installation for python use pip from the get go

To install pip:

$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python2 get-pip.py   # for python 2.7
$ sudo python3 get-pip.py   # for python 3.x

To install scipy using pip:

$ pip2 install scipy    # for python 2.7
$ pip3 install scipy    # for python 3.x

Bookmarking this URL should give you a full-screen compose window, without any distractions:

https://mail.google.com/mail/?view=cm&fs=1&tf=1

Additionally, if you want to be future-proof (see for instance how other URLs in this question stopped working) you can bookmark a link to:

mailto:

It will open your default email client and you probably already have Gmail configured for that purpose.

Alternatively:

1. Save current changes to a temp stash:

   $ git stash

2. Create a new branch based on this stash, and switch to the new branch:

   $ git stash branch <new-branch> stash@{0}

Tip: use tab key to reduce typing the stash name.

Delete the CMakeCache.txt file and try this:

cmake -G %1 -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DBUILD_TESTS=ON ..

You have to enter all your command-line definitions before including the path.

1. Start SQL Server Management Studio
2. Connect to your database
3. File > Open > File and pick your file
4. Execute it

What eventually worked for me, after lot's of confusing manuals and confusing tutorials, since Docker is obviously at time of my writing at peek of inflated expectations, is:

1. Save the docker image into archive:
   docker save image_name > image_name.tar
2. copy on another machine
3. on that other docker machine, run docker load in a following way:
   cat image_name.tar | docker load

Export and import, as proposed in another answers does not export ports and variables, which might be required for your container to run. And you might end up with stuff like "No command specified" etc... When you try to load it on another machine.

So, difference between save and export is that save command saves whole image with history and metadata, while export command exports only files structure (without history or metadata).

Needless to say is that, if you already have those ports taken on the docker hyper-visor you are doing import, by some other docker container, you will end-up in conflict, and you will have to reconfigure exposed ports.

Note: In order to move data with docker, you might be having persistent storage somewhere, which should also be moved alongside with containers.

I tried most of the answers but still couldn't get it to work. This worked for me:

right click on reference -> properties -> change 'Specific Version' to false.

Hope this Helps.

You can also try this:

var data= _.reverse(_.sortBy(res.locals.subscriptionList.items, ['type', 'name']));

• @PathVariable is to obtain some placeholder from the URI (Spring call it an URI Template) — see Spring Reference Chapter 16.3.2.2 URI Template Patterns
• @RequestParam is to obtain a parameter from the URI as well — see Spring Reference Chapter 16.3.3.3 Binding request parameters to method parameters with @RequestParam

If the URL http://localhost:8080/MyApp/user/1234/invoices?date=12-05-2013 gets the invoices for user 1234 on December 5th, 2013, the controller method would look like:

@RequestMapping(value="/user/{userId}/invoices", method = RequestMethod.GET)
public List<Invoice> listUsersInvoices(
            @PathVariable("userId") int user,
            @RequestParam(value = "date", required = false) Date dateOrNull) {
  ...
}

Also, request parameters can be optional, and as of Spring 4.3.3 path variables can be optional as well. Beware though, this might change the URL path hierarchy and introduce request mapping conflicts. For example, would /user/invoices provide the invoices for user null or details about a user with ID "invoices"?

Notepad++ 7.5.8 does not have plugin manager by default. You have to download plugins manually.

Keep in mind, if you use 64 bit version of Notepad++, you should also use 64 bit version of plugin. I had a similar issue here.

In SQL Server, you would say:

Select name from users
UNION [ALL]
SELECT 'JASON'

In Oracle, you would say

Select name from user
UNION [ALL]
Select 'JASON' from DUAL

Seems I don't have enough rep to post a comment, so another answer will have to do.

When you unlink a node using removeChild() or by setting the innerHTML property on the parent, you also need to make sure that there is nothing else referencing it otherwise it won't actually be destroyed and will lead to a memory leak. There are lots of ways in which you could have taken a reference to the node before calling removeChild() and you have to make sure those references that have not gone out of scope are explicitly removed.

Doug Crockford writes here that event handlers are known a cause of circular references in IE and suggests removing them explicitly as follows before calling removeChild()

function purge(d) {
    var a = d.attributes, i, l, n;
    if (a) {
        for (i = a.length - 1; i >= 0; i -= 1) {
            n = a[i].name;
            if (typeof d[n] === 'function') {
                d[n] = null;
            }
        }
    }
    a = d.childNodes;
    if (a) {
        l = a.length;
        for (i = 0; i < l; i += 1) {
            purge(d.childNodes[i]);
        }
    }
}

And even if you take a lot of precautions you can still get memory leaks in IE as described by Jens-Ingo Farley here.

And finally, don't fall into the trap of thinking that Javascript delete is the answer. It seems to be suggested by many, but won't do the job. Here is a great reference on understanding delete by Kangax.

1) If general mysql logging is enabled then we can check the queries in the log file or table based what we have mentioned in the config. Check what is enabled with the following command

mysql> show variables like 'general_log%';
mysql> show variables like 'log_output%';

If we need query history in table then

Execute SET GLOBAL log_output = 'TABLE';
Execute SET GLOBAL general_log = 'ON';

Take a look at the table mysql.general_log

If you prefer to output to a file:

SET GLOBAL log_output = "FILE"; which is set by default.
SET GLOBAL general_log_file = "/path/to/your/logfile.log";
SET GLOBAL general_log = 'ON';

2) We can also check the queries in the .mysql_history file cat ~/.mysql_history

as simple as:

tmpHM.each{ key, value -> 
  doSomethingWithKeyAndValue key, value
}

I used to use the Key Listener for this but I failed big time with that approach. Best approach as recommended already is to use a DocumentFilter. Below is a utility method I created for building textfields with only number input. Just beware that it'll also take single '.' character as well since it's usable for decimal input.

public static void installNumberCharacters(AbstractDocument document) {
        document.setDocumentFilter(new DocumentFilter() {
            @Override
            public void insertString(FilterBypass fb, int offset,
                    String string, AttributeSet attr)
                    throws BadLocationException {
                try {
                    if (string.equals(".")
                            && !fb.getDocument()
                                    .getText(0, fb.getDocument().getLength())
                                    .contains(".")) {
                        super.insertString(fb, offset, string, attr);
                        return;
                    }
                    Double.parseDouble(string);
                    super.insertString(fb, offset, string, attr);
                } catch (Exception e) {
                    Toolkit.getDefaultToolkit().beep();
                }

            }

            @Override
            public void replace(FilterBypass fb, int offset, int length,
                    String text, AttributeSet attrs)
                    throws BadLocationException {
                try {
                    if (text.equals(".")
                            && !fb.getDocument()
                                    .getText(0, fb.getDocument().getLength())
                                    .contains(".")) {
                        super.insertString(fb, offset, text, attrs);
                        return;
                    }
                    Double.parseDouble(text);
                    super.replace(fb, offset, length, text, attrs);
                } catch (Exception e) {
                    Toolkit.getDefaultToolkit().beep();
                }
            }
        });
    }

How about this

for (int i = 0; i < str.length(); i++) { 
    System.out.println(str.substring(i, i + 1)); 
} 

Apparently, the compiler thinks NSSearchPathDirectory:0 is an array, and of course it expects the type NSSearchPathDirectory instead. Certainly not a helpful error message.

But as to the reasons:

First, you are confusing the argument names and types. Take a look at the function definition:

func NSSearchPathForDirectoriesInDomains(
    directory: NSSearchPathDirectory,
    domainMask: NSSearchPathDomainMask,
    expandTilde: Bool) -> AnyObject[]!

• directory and domainMask are the names, you are using the types, but you should leave them out for functions anyway. They are used primarily in methods.
• Also, Swift is strongly typed, so you shouldn't just use 0. Use the enum's value instead.
• And finally, it returns an array, not just a single path.

So that leaves us with (updated for Swift 2.0):

let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]

and for Swift 3:

let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]

I've used the jdbcsql project on Sourceforge.

On *nix systems, this will create a csv stream of results to standard out:

java -Djava.security.egd=file///dev/urandom -jar jdbcsql.jar -d oracledb_SID -h $host -p 1521 -U some_username -m oracle -P "$PW" -f excel -s "," "$1"

Note that adding the -Djava.security.egd=file///dev/urandom increases performance greatly

Windows commands are similar: see http://jdbcsql.sourceforge.net/

You may want to go look at the SQL Injection article on Wikipedia. Look under the "Hexadecimal Conversion" part to find a small function to do your SQL commands and return an array with the information in it.

https://en.wikipedia.org/wiki/SQL_injection

I wrote the dosql() function because I got tired of having my SQL commands executing all over the place, forgetting to check for errors, and being able to log all of my commands to a log file for later viewing if need be. The routine is free for whoever wants to use it for whatever purpose. I actually have expanded on the function a bit because I wanted it to do more but this basic function is a good starting point for getting the output back from an SQL call.

I have solved this creating a custom View:

public class FractionalSizeView extends View {
  public FractionalSizeView(Context context, AttributeSet attrs) {
    super(context, attrs);
  }

  public FractionalSizeView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
  }

  @Override
  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int width = MeasureSpec.getSize(widthMeasureSpec);
    setMeasuredDimension(width * 70 / 100, 0);
  }
}

This is invisible strut I can use to align other views within RelativeLayout.

There is also a great hacking game the name of which I simply cannot remember. Hrm.

@PrePersist
void preInsert() {
    if (this.dateOfConsent == null)
        this.dateOfConsent = LocalDateTime.now();
    if(this.consentExpiry==null)
        this.consentExpiry = this.dateOfConsent.plusMonths(3);
}

In my case due to the field being LocalDateTime i used this, it is recommended due to vendor independence

This works for me under Specific Page for MVC:

You need an assignment operator so that:

arrayOfAs[i] = A(3);

works as it should.

0 and 7 both stand for Sunday, you can use the one you want, so writing 0-6 or 1-7 has the same result.

Also, as suggested by @Henrik, it is possible to replace numbers by shortened name of days, such as MON, THU, etc:

0 - Sun      Sunday
1 - Mon      Monday
2 - Tue      Tuesday
3 - Wed      Wednesday
4 - Thu      Thursday
5 - Fri      Friday
6 - Sat      Saturday
7 - Sun      Sunday

Graphically:

 +---------- minute (0 - 59)
 ¦ +-------- hour (0 - 23)
 ¦ ¦ +------ day of month (1 - 31)
 ¦ ¦ ¦ +---- month (1 - 12)
 ¦ ¦ ¦ ¦ +-- day of week (0 - 6 => Sunday - Saturday, or
 ¦ ¦ ¦ ¦ ¦                1 - 7 => Monday - Sunday)
 ? ? ? ? ?
 * * * * * command to be executed

Finally, if you want to specify day by day, you can separate days with commas, for example SUN,MON,THU will exectute the command only on sundays, mondays on thursdays.

You can read further details in Wikipedia's article about Cron.

Here is the standard formula to extract the values of attribute and text using XPath-

1. To extract attribute value for Web Element-

   elementXPath/@attributeName

2. To extract text value for Web Element-

   elementXPath/text()

In your case here is the xpath which will return

//parent[@name='Parent_1']//child/@name

It will return:

Child_2
Child_4
Child_1
Child_3

Hope that will help you

This problem occurs in the Response.Redirect and Server.Transfer methods, because both methods call Response.End internally.

The solution for this problem is as follows.

For Server.Transfer, use the Server.Execute method instead.

Visit this link for download an example.

The following should do the trick:

div[class^='myclass'], div[class*=' myclass']{
    color: #F00;
}

Edit: Added wildcard (*) as suggested by David

onmouseover="$('.play-detail').stop().animate({'height': '84px'},'300');" 

onmouseout="$('.play-detail').stop().animate({'height': '44px'},'300');"

Just put two stops -- one onmouseover and one onmouseout.

The question is old and answered, but I think it may be useful to have this answer if you want to use the newly released DataBinding tools for Android, just set this in your XML :

<data>
    <variable name="stringValue" type="String"/>
</data>
...
<EditText
        ...
        android:text="@={stringValue}"
        android:selection="@{stringValue.length()}"
        ...
/>

You can look here Can the key in a Java property include a blank character?

for escape equal '=' \u003d

table.whereclause=where id=100

key:[table.whereclause] value:[where id=100]

table.whereclause\u003dwhere id=100

key:[table.whereclause=where] value:[id=100]

table.whereclause\u003dwhere\u0020id\u003d100

key:[table.whereclause=where id=100] value:[]

Very simple just two commands

For IOS $ react-native log-ios
For Android $ react-native log-android

1NF: Only one value per column

2NF: All the non primary key columns in the table should depend on the entire primary key.

3NF: All the non primary key columns in the table should depend DIRECTLY on the entire primary key.

I have written an article in more detail over here

I finally got a proof-of-concept project to work, so I will share it here.

Set up the layout

The layout is set up like this, where the light grey area is the VideoView.

activity_main.xml

    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.videotest.MainActivity">

        android:layout_width="300dp"
        android:layout_height="200dp"/>

    <Button
        android:text="Play"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:onClick="onButtonClick"
        android:id="@+id/button"/>

</RelativeLayout>

Prepare video clip

According to the documentation, Android should support mp4 H.264 playback (decoding) for all API levels. However, there seem to be a lot of factors that affect whether an actual video will play or not. The most in depth answer I could find that told how to encode the videos is here. It uses the powerful ffmpeg command line tool to do the conversion to something that should be playable on all (hopefully?) Android devices. Read the answer I linked to for more explanation. I used a slightly modified version because I was getting errors with the original version.

ffmpeg -y -i input_file.avi -s 432x320 -b:v 384k -vcodec libx264 -flags +loop+mv4 -cmp 256 -partitions +parti4x4+parti8x8+partp4x4+partp8x8 -subq 6 -trellis 0 -refs 5 -bf 0 -coder 0 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -qmin 10 -qmax 51 -qdiff 4 -c:a aac -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 -strict -2 output_file.mp4

I would definitely read up a lot more on each of those parameters to see which need adjusting as far as video and audio quality go.

Next, rename output_file.mp4 to test.mp4 and put it in your Android project's /res/raw folder. Create the folder if it doesn't exist already.

Code

There is not much to the code. The video plays when the "Play" button is clicked. Thanks to this answer for help.

var json = "{'@STARTDATE': '2016-02-17 00:00:00.000',  '@ENDDATE': '2016-02-18 23:59:00.000' }";
var fdate = JObject.Parse(json)["@STARTDATE"];

The most direct way is sum(numbers == x).

numbers == x creates a logical vector which is TRUE at every location that x occurs, and when suming, the logical vector is coerced to numeric which converts TRUE to 1 and FALSE to 0.

However, note that for floating point numbers it's better to use something like: sum(abs(numbers - x) < 1e-6).

The API Demos in the Android SDK have an example that does just that.

It's under DIALOG_TEXT_ENTRY. They have a layout, inflate it with a LayoutInflater, and use that as the View.

EDIT: What I had linked to in my original answer is stale. Here is a mirror.

Can you provide a link ? thanks I can take a look Most likely your css selector isnt strong enough or can you try

padding:0!important;

x = [i for i in x if len(i)==2]

I had the same error. I have a tab bar with 3 items and I was unconsciously trying to call the root view controller of item 1 in the item 2 of my tab bar using performSegueWithIdentifier.

What happens is that it calls the view controller and goes back to the root view controller of item 2 after a few seconds and logs that error.

Apparently, you cannot call the root view controller of an item to another item.

So instead of performSegueWithIdentifier

I used [self.parentViewController.tabBarController setSelectedIndex:0];

Hope this helps someone.

It means you compiled with e.g. gcc -O3 and the gcc optimiser found that some of your variables were redundant in some way that allowed them to be optimised away. In this particular case you appear to have three variables a, b, c with the same value and presumably they can all be aliassed to a single variable. Compile with optimisation disabled, e.g. gcc -O0, if you want to see such variables (this is generally a good idea for debug builds in any case).

Do not include bin in your JAVA_HOME env variable

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

It would seem to me that though you have ODP with the Oracle Istant Client, the ODP may be trying to use the actual Oracle Client instead. Do you have a standard Oracle client installed on the machine as well? I recall Oracle being quite picky about when it came to multiple clients on the same machine.

In Java we can scroll by using JavaScript, like in the following code:

driver.getEval("var elm = window.document.getElementById('scrollDiv'); if (elm.scrollHeight > elm.clientHeight){elm.scrollTop = elm.scrollHeight;}");

You can assign a desired value to the "elm.scrollTop" variable.

The simple answer (swift 3):

Calendar.current.component(.weekday, from: Date())

Sounds like you're doing this:

0..10.to_a

The warning is from Fixnum#to_a, not from Range#to_a. Try this instead:

(0..10).to_a

This is what I do, just add \n and use encodeURIComponent

Example

var emailBody = "1st line.\n 2nd line \n 3rd line";

emailBody = encodeURIComponent(emailBody);

href = "mailto:[email protected]?body=" + emailBody;

Check encodeURIComponent docs

You can use format or formatC to, ahem, format your axis labels.

For whole numbers, try

x <- 10 ^ (1:10)
format(x, scientific = FALSE)
formatC(x, digits = 0, format = "f")

If the numbers are convertable to actual integers (i.e., not too big), you can also use

formatC(x, format = "d")

How you get the labels onto your axis depends upon the plotting system that you are using.

You can simply request https://graph.facebook.com/me?access_token=xxxxxxxxxxxxxxxxx if you get an error, the token is invalid. If you get a JSON object with an id property then it is valid.

Unfortunately this will only tell you if your token is valid, not if it came from your app.

To print a schema, I use jade and do an export to a file of the database then bring it into word to format and print

The first step would be to add

position: 'absolute',

then if you want the element full width, add

left: 0,
right: 0,

then, if you want to put the element in the bottom, add

bottom: 0,
// don't need set top: 0

if you want to position the element at the top, replace bottom: 0 by top: 0

Pythonic way to get text from Span tags:

driver.find_element_by_xpath("//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel clear')]").text

Updated answer

Here is how to change the box model used by the input/textarea/select elements so that they all behave the same way. You need to use the box-sizing property which is implemented with a prefix for each browser

-ms-box-sizing:content-box;
-moz-box-sizing:content-box;
-webkit-box-sizing:content-box; 
box-sizing:content-box;

This means that the 2px difference we mentioned earlier does not exist..

example at http://www.jsfiddle.net/gaby/WaxTS/5/

note: On IE it works from version 8 and upwards..

Original

if you reset their borders then the select element will always be 2 pixels less than the input elements..

example: http://www.jsfiddle.net/gaby/WaxTS/2/

You can type them manually but the editor will assist you.

You can see the snap sot below.

As soon as you type "a" inside the quotes you get a list of permissions and also hint to move caret up and down to select the same.

AFAIK the files in the assets directory don't get unpacked. Instead, they are read directly from the APK (ZIP) file.

So, you really can't make stuff that expects a file accept an asset 'file'.

Instead, you'll have to extract the asset and write it to a seperate file, like Dumitru suggests:

  File f = new File(getCacheDir()+"/m1.map");
  if (!f.exists()) try {

    InputStream is = getAssets().open("m1.map");
    int size = is.available();
    byte[] buffer = new byte[size];
    is.read(buffer);
    is.close();


    FileOutputStream fos = new FileOutputStream(f);
    fos.write(buffer);
    fos.close();
  } catch (Exception e) { throw new RuntimeException(e); }

  mapView.setMapFile(f.getPath());

I use the same code doing that all the time, so added a simple jquery plugin doing it. 480 bytes long, and fast. Only bound elements analyzed in runtime.

https://www.npmjs.com/package/jquery-on-scrolled-to

It will be $('#scroll-to').onScrolledTo(0, function() { alert('you have scrolled to the h1!'); });

or use 0.5 instead of 0 if need to alert when half of the h1 shown.

Like the other answers said, sp_reset_connection indicates that connection pool is being reused. Be aware of one particular consequence!

Jimmy Mays' MSDN Blog said:

sp_reset_connection does NOT reset the transaction isolation level to the server default from the previous connection's setting.

UPDATE: Starting with SQL 2014, for client drivers with TDS version 7.3 or higher, the transaction isolation levels will be reset back to the default.

ref: SQL Server: Isolation level leaks across pooled connections

Here is some additional information:

What does sp_reset_connection do?

Data access API's layers like ODBC, OLE-DB and System.Data.SqlClient all call the (internal) stored procedure sp_reset_connection when re-using a connection from a connection pool. It does this to reset the state of the connection before it gets re-used, however nowhere is documented what things get reset. This article tries to document the parts of the connection that get reset.

sp_reset_connection resets the following aspects of a connection:

• All error states and numbers (like @@error)

• Stops all EC's (execution contexts) that are child threads of a parent EC executing a parallel query

• Waits for any outstanding I/O operations that is outstanding

• Frees any held buffers on the server by the connection

• Unlocks any buffer resources that are used by the connection

• Releases all allocated memory owned by the connection

• Clears any work or temporary tables that are created by the connection

• Kills all global cursors owned by the connection

• Closes any open SQL-XML handles that are open

• Deletes any open SQL-XML related work tables

• Closes all system tables

• Closes all user tables

• Drops all temporary objects

• Aborts open transactions

• Defects from a distributed transaction when enlisted

• Decrements the reference count for users in current database which releases shared database locks

• Frees acquired locks

• Releases any acquired handles

• Resets all SET options to the default values

• Resets the @@rowcount value

• Resets the @@identity value

• Resets any session level trace options using dbcc traceon()

• Resets CONTEXT_INFO to NULL in SQL Server 2005 and newer _{[ not part of the original article ]}

sp_reset_connection will NOT reset:

• Security context, which is why connection pooling matches connections based on the exact connection string

• Application roles entered using sp_setapprole, since application roles could not be reverted at all prior to SQL Server 2005. Starting in SQL Server 2005, app roles can be reverted, but only with additional information that is not part of the session. Before closing the connection, application roles need to be manually reverted via sp_unsetapprole using a "cookie" value that is captured when sp_setapprole is executed.

Note: I am including the list here as I do not want it to be lost in the ever transient web.

CommonJS is more than that - it's a project to define a common API and ecosystem for JavaScript. One part of CommonJS is the Module specification. Node.js and RingoJS are server-side JavaScript runtimes, and yes, both of them implement modules based on the CommonJS Module spec.

AMD (Asynchronous Module Definition) is another specification for modules. RequireJS is probably the most popular implementation of AMD. One major difference from CommonJS is that AMD specifies that modules are loaded asynchronously - that means modules are loaded in parallel, as opposed to blocking the execution by waiting for a load to finish.

AMD is generally more used in client-side (in-browser) JavaScript development due to this, and CommonJS Modules are generally used server-side. However, you can use either module spec in either environment - for example, RequireJS offers directions for running in Node.js and browserify is a CommonJS Module implementation that can run in the browser.

Operating system commands have exit codes. Look for Linux exit codes to see some material on this. The shell uses the exit codes to decide if the program worked, had problems, or failed. There are some efforts to create standard (or at least commonly-used) exit codes. See this Advanced Shell Script posting.

There are a few ways to get all unique combinations of a set of factors.

with(df, interaction(yad, per, drop=TRUE))   # gives labels
with(df, yad:per)                            # ditto

aggregate(numeric(nrow(df)), df[c("yad", "per")], length)    # gives a data frame

Create a Map or a Set, and using "on connection" event set to it each connected socket, in reverse "once disconnect" event delete that socket from the Map we created earlier

import * as Server from 'socket.io';

const io = Server();
io.listen(3000);

const connections = new Set();

io.on('connection', function (s) {

  connections.add(s);

  s.once('disconnect', function () {
    connections.delete(s);
  });

});

That header doesn't exist in standard C++. It was part of some pre-1990s compilers, but it is certainly not part of C++.

Use #include <iostream> instead. And all the library classes are in the std:: namespace, for ex­am­ple std::cout.

Also, throw away any book or notes that mention the thing you said.

Try this:

var request = WebRequest.Create("http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG");

using (var response = request.GetResponse())
using (var stream = response.GetResponseStream())
{
    pictureBox1.Image = Bitmap.FromStream(stream);
}

just return true inside your if statement

var myArr = [1,2,3,4];

myArr.forEach(function(elem){
  if (elem === 3) {

      return true;

    // Go to "next" iteration. Or "continue" to next iteration...
  }

  console.log(elem);
});

In my case, I had several applications installed having the same domain name in the package name as follows.

com.mypackage.app1
com.mypackage.app2
com.mypackage.app3 
...

I had to uninstall all the apps having similar package names and reinstall them again in order to get rid of the problem.

To find all package names from the device I used the following.

adb shell pm list packages

Then I grabbed the packages that match my package name that I am looking for.

dumpsys | grep -A18 "Package \[com.mypackage\]"

Then uninstalled all the apps having that domain.

uninstall com.mypackage.app1
uninstall com.mypackage.app2
uninstall com.mypackage.app3
...

You can also uninstall the applications using the Settings app. Go to the Settings -> Apps -> Find the app -> Uninstall

Hope that helps someone having the same problem as me.

If you develop under Eclipse, you can in the POM Editor (advanced tabs enabled) dependency graph look for the dependency you want to exclude of your project and then:

right click on it -> "Exclude Maven Artifact ..." and Eclipse will make the exclusion for you without the need to find out on which dependency the lib is linked.

You could also try exectimer. It gives you feedback like:

var t = require("exectimer");

var myFunction() {
   var tick = new t.tick("myFunction");
   tick.start();
   // do some processing and end this tick
   tick.stop();
}

// Display the results
console.log(t.timers.myFunction.duration()); // total duration of all ticks
console.log(t.timers.myFunction.min()); // minimal tick duration
console.log(t.timers.myFunction.max()); // maximal tick duration
console.log(t.timers.myFunction.mean()); // mean tick duration
console.log(t.timers.myFunction.median()); // median tick duration

[edit] There is an even simpler way now to use exectime. Your code could be wrapped like this:

var t = require('exectimer'),
Tick = t.Tick;

for(var i = 1; i < LIMIT; i++){
    Tick.wrap(function saveUsers(done) {
        db.users.save({id : i, name : "MongoUser [" + i + "]"}, function(err, saved) {
            if( err || !saved ) console.log("Error");
            else console.log("Saved");
            done();
        });
    });
}

// Display the results
console.log(t.timers.myFunction.duration()); // total duration of all ticks
console.log(t.timers.saveUsers.min()); // minimal tick duration
console.log(t.timers.saveUsers.max()); // maximal tick duration
console.log(t.timers.saveUsers.mean()); // mean tick duration
console.log(t.timers.saveUsers.median()); // median tick duration

set up a new postgresql server and replace its data folder with the files from your external disk.

You will then be able to start that postgresql server up and retrieve the data using pg_dump (pg_dump -s for the schema-only as mentioned)

If you really want DELETE FROM some_table CASCADE; which means "remove all rows from table some_table", you can use TRUNCATE instead of DELETE and CASCADE is always supported. However, if you want to use selective delete with a where clause, TRUNCATE is not good enough.

USE WITH CARE - This will drop all rows of all tables which have a foreign key constraint on some_table and all tables that have constraints on those tables, etc.

Postgres supports CASCADE with TRUNCATE command:

TRUNCATE some_table CASCADE;

Handily this is transactional (i.e. can be rolled back), although it is not fully isolated from other concurrent transactions, and has several other caveats. Read the docs for details.

There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..

At the very simplest, you would catch urllib2.URLError:

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    raise MyException("There was an error: %r" % e)

The following should capture the specific error raised when the connection times out:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    # For Python 2.6
    if isinstance(e.reason, socket.timeout):
        raise MyException("There was an error: %r" % e)
    else:
        # reraise the original error
        raise
except socket.timeout, e:
    # For Python 2.7
    raise MyException("There was an error: %r" % e)

I know it's many years later, but I had been working on a similar issue recently and I wanted to post my solution. The currently accepted answer pads out the exponent part with 0's, and mine attempts to find the exact answer, although in general it isn't perfectly accurate for very large numbers because of JS's limit in floating point precision.

This does work for Math.pow(2, 100), returning the correct value of 1267650600228229401496703205376.

pgrep can get you all of the child PIDs of a parent process. As mentioned earlier $$ is the current scripts PID. So, if you want a script that cleans up after itself, this should do the trick:

trap 'kill $( pgrep -P $$ | tr "\n" " " )' SIGINT SIGTERM EXIT

You can use this syntax if some grads are attached with your variables.

I would like to echo Jason's response though sometimes you need to naively parse some Html and pull out the text content.

I needed to do this with some Html which had been created by a rich text editor, always fun and games.

In this case you may need to remove the content of some tags as well as just the tags themselves.

In my case and tags were thrown into this mix. Some one may find my (very slightly) less naive implementation a useful starting point.

   /// <summary>
    /// Removes all html tags from string and leaves only plain text
    /// Removes content of <xml></xml> and <style></style> tags as aim to get text content not markup /meta data.
    /// </summary>
    /// <param name="input"></param>
    /// <returns></returns>
    public static string HtmlStrip(this string input)
    {
        input = Regex.Replace(input, "<style>(.|\n)*?</style>",string.Empty);
        input = Regex.Replace(input, @"<xml>(.|\n)*?</xml>", string.Empty); // remove all <xml></xml> tags and anything inbetween.  
        return Regex.Replace(input, @"<(.|\n)*?>", string.Empty); // remove any tags but not there content "<p>bob<span> johnson</span></p>" becomes "bob johnson"
    }

First, Set :
ALTER TABLE person ALTER COLUMN phone DROP NOT NULL;

That's a very general question. One answer is: "it depends what kind of UUID you wish to generate". But a better one is this: "Well, before I answer, can you tell us why you need to code up your own UUID generation algorithm instead of calling the UUID generation functionality that most modern operating systems provide?"

Doing that is easier and safer, and since you probably don't need to generate your own, why bother coding up an implementation? In that case, the answer becomes use whatever your O/S, programming language or framework provides. For example, in Windows, there is CoCreateGuid or UuidCreate or one of the various wrappers available from the numerous frameworks in use. In Linux there is uuid_generate.

If you, for some reason, absolutely need to generate your own, then at least have the good sense to stay away from generating v1 and v2 UUIDs. It's tricky to get those right. Stick, instead, to v3, v4 or v5 UUIDs.

Update: In a comment, you mention that you are using Python and link to this. Looking through the interface provided, the easiest option for you would be to generate a v4 UUID (that is, one created from random data) by calling uuid.uuid4().

If you have some data that you need to (or can) hash to generate a UUID from, then you can use either v3 (which relies on MD5) or v5 (which relies on SHA1). Generating a v3 or v5 UUID is simple: first pick the UUID type you want to generate (you should probably choose v5) and then pick the appropriate namespace and call the function with the data you want to use to generate the UUID from. For example, if you are hashing a URL you would use NAMESPACE_URL:

uuid.uuid3(uuid.NAMESPACE_URL, 'https://ripple.com')

Please note that this UUID will be different than the v5 UUID for the same URL, which is generated like this:

uuid.uuid5(uuid.NAMESPACE_URL, 'https://ripple.com')

A nice property of v3 and v5 URLs is that they should be interoperable between implementations. In other words, if two different systems are using an implementation that complies with RFC4122, they will (or at least should) both generate the same UUID if all other things are equal (i.e. generating the same version UUID, with the same namespace and the same data). This property can be very helpful in some situations (especially in content-addressible storage scenarios), but perhaps not in your particular case.

If you are using Windows S.O. make sure it is in the folder:

C:\Users\**your-user-name**\AppData\Local\Android\Sdk\platform-tools

Otherwise, open Android Studio and go to:

Tools> SDK Manager> Android SDK> SDK Tools

Select the Android Platform-Tools and Android SDK Tools checkbox and click Apply. After download check the directory again.

You should be okay to just take the height property out of the CSS.

Well, me also I was struggling with this issue: this is how I solved it: apply table-layout: auto; to the <table> element.

Java generics are mostly compile time, this means that the type information is lost at runtime.

class GenericCls<T>
{
    T t;
}

will be compiled to something like

class GenericCls
{
   Object o;
}

To get the type information at runtime you have to add it as an argument of the ctor.

class GenericCls<T>
{
     private Class<T> type;
     public GenericCls(Class<T> cls)
     {
        type= cls;
     }
     Class<T> getType(){return type;}
}

Example:

GenericCls<?> instance = new GenericCls<String>(String.class);
assert instance.getType() == String.class;

I had a slightly different problem. The credential problem was for the underlying user running the application, not the user trying to login. One way to test this is to go to IIS Management -> Sites -> Your Site -> Basic Settings -> Test Settings.

In the accepted answer by @chuck, there is a comment saying it will not work in the case of FK.

it worked for me, case of EF6 .Net4.7.2

public class OnCallDay
{
     public int Id { get; set; }
    //[Key]
    [Index("IX_OnCallDateEmployee", 1, IsUnique = true)]
    public DateTime Date { get; set; }
    [ForeignKey("Employee")]
    [Index("IX_OnCallDateEmployee", 2, IsUnique = true)]
    public string EmployeeId { get; set; }
    public virtual ApplicationUser Employee{ get; set; }
}

Yes, Its possible in SQL, but we can't set more than one primary keys in MsAccess. Then, I don't know about the other databases.

CREATE TABLE CHAPTER (
    BOOK_ISBN VARCHAR(50) NOT NULL,
    IDX INT NOT NULL,
    TITLE VARCHAR(100) NOT NULL,
    NUM_OF_PAGES INT,
    PRIMARY KEY (BOOK_ISBN, IDX)
);

    public static void createUserRole(string roleName)
    {
        if (!System.Web.Security.Roles.RoleExists(roleName))
        {
            System.Web.Security.Roles.CreateRole(roleName);
        }
    }

The closet equivalent is to create a nested class which will be able to access the outer class' private members. Something like this:

class Outer
{
    class Inner
    {
       // This class can access Outer's private members
    }
}

or if you prefer to put the Inner class in another file:

Outer.cs
partial class Outer
{
}


Inner.cs
partial class Outer
{
    class Inner
    {
       // This class can access Outer's private members
    }
}

ByteArrayInputStream extends InputStream:

InputStream myInputStream = new ByteArrayInputStream(myBytes); 

It will group by the column position you put after the group by clause.

for example if you run 'SELECT SALESMAN_NAME, SUM(SALES) FROM SALES GROUP BY 1' it will group by SALESMAN_NAME.

One risk on doing that is if you run 'Select *' and for some reason you recreate the table with columns on a different order, it will give you a different result than you would expect.

plt.imsave worked for me. You can find the documentation here: https://matplotlib.org/3.2.1/api/_as_gen/matplotlib.pyplot.imsave.html

#file_path = directory address where the image will be stored along with file name and extension
#array = variable where the image is stored. I think for the original post this variable is im_np
plt.imsave(file_path, array)

Use a pattern along these lines:

function getValue(file) {
  return lookupValue(file);
}

getValue('myFile.txt').then(function(res) {
  // do whatever with res here
});

(although this is a bit redundant, I'm sure your actual code is more complicated)

A small variation of Sean's answer:

With the asterisk in order to spring search files 'spring-config.xml' anywhere in the classpath.

For Swift 3 & Swift 4 :

Since UIAlertView is deprecated, there is the good way for display Alert on Swift 3

let alertController = UIAlertController(title: NSLocalizedString("No network connection",comment:""), message: NSLocalizedString("connected to the internet to use this app.",comment:""), preferredStyle: .alert)
let defaultAction = UIAlertAction(title:     NSLocalizedString("Ok", comment: ""), style: .default, handler: { (pAlert) in
                //Do whatever you want here
        })
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)

Deprecated :

This is the swift version inspired by the checked response :

Display AlertView :

   let alert = UIAlertView(title: "No network connection", 
                           message: "You must be connected to the internet to use this app.", delegate: nil, cancelButtonTitle: "Ok")
    alert.delegate = self
    alert.show()

Add the delegate to your view controller :

class AgendaViewController: UIViewController, UIAlertViewDelegate

When user click on button, this code will be executed :

func alertView(alertView: UIAlertView, clickedButtonAtIndex buttonIndex: Int) {


}

Have you tried with: replacing ((rand() % 10000) / 10000.0), with:(rand() % 2). This worked for me!

So you could do something like this:

double r2()
{
     srand(time(NULL));
     return(rand() % 2);
}

Here's what we came up with for copying one field to another for ~150_000 records. It took about 6 minutes, but is still significantly less resource intensive than it would have been to instantiate and iterate over the same number of ruby objects.

js_query = %({
  $or : [
    {
      'settings.mobile_notifications' : { $exists : false },
      'settings.mobile_admin_notifications' : { $exists : false }
    }
  ]
})

js_for_each = %(function(user) {
  if (!user.settings.hasOwnProperty('mobile_notifications')) {
    user.settings.mobile_notifications = user.settings.email_notifications;
  }
  if (!user.settings.hasOwnProperty('mobile_admin_notifications')) {
    user.settings.mobile_admin_notifications = user.settings.email_admin_notifications;
  }
  db.users.save(user);
})

js = "db.users.find(#{js_query}).forEach(#{js_for_each});"
Mongoid::Sessions.default.command('$eval' => js)

Here is a minimal design that should work fine. What you have to do is to simply inherit Observer in a class and afterwards use observe(event_name, callback_fn) to listen for a specific event. Whenever that specific event is fired anywhere in the code (ie. Event('USB connected')), the corresponding callback will fire.

class Observer():
    _observers = []
    def __init__(self):
        self._observers.append(self)
        self._observed_events = []
    def observe(self, event_name, callback_fn):
        self._observed_events.append({'event_name' : event_name, 'callback_fn' : callback_fn})


class Event():
    def __init__(self, event_name, *callback_args):
        for observer in Observer._observers:
            for observable in observer._observed_events:
                if observable['event_name'] == event_name:
                    observable['callback_fn'](*callback_args)

Example:

class Room(Observer):
    def __init__(self):
        print("Room is ready.")
        Observer.__init__(self) # DON'T FORGET THIS
    def someone_arrived(self, who):
        print(who + " has arrived!")

# Observe for specific event
room = Room()
room.observe('someone arrived',  room.someone_arrived)

# Fire some events
Event('someone left',    'John')
Event('someone arrived', 'Lenard') # will output "Lenard has arrived!"
Event('someone Farted',  'Lenard')

Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)

No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.

I had this issue upgrading from Java 8 to 11. After adding this dependency, my app launched without issue:

    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.25.0-GA</version>
</dependency>

There isn't really a formal manual, because there's no single style or standard.

So long as you understand the rules of identifier naming you can use whatever you like.

In practice, I find it easier to use lower_case_underscore_separated_identifiers because it isn't necessary to "Double Quote" them everywhere to preserve case, spaces, etc.

If you wanted to name your tables and functions "@MyA??! ""betty"" Shard$42" you'd be free to do that, though it'd be pain to type everywhere.

The main things to understand are:

• Unless double-quoted, identifiers are case-folded to lower-case, so MyTable, MYTABLE and mytable are all the same thing, but "MYTABLE" and "MyTable" are different;

• Unless double-quoted:

  SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

• You must double-quote keywords if you wish to use them as identifiers.

In practice I strongly recommend that you do not use keywords as identifiers. At least avoid reserved words. Just because you can name a table "with" doesn't mean you should.

This is a known issue in the project system. See dotnet/project-system#1741

// WPF

// Defined Color
button1.Background = Brushes.Green;

// Color from RGB
button2.Background = new SolidColorBrush(Color.FromArgb(255, 0, 255, 0));

Generally any change in the .htaccess should have visible effects. If no effect, check your configuration apache files, something like:

<Directory ..>
    ...
    AllowOverride None
    ...
</Directory>

Should be changed to

AllowOverride All

And you'll be able to change directives in .htaccess files.

Using variable notation, you can do it without a temporary file:

${C:\file.txt} = ${C:\file.txt} | select -skip 1

function Remove-Topline ( [string[]]$path, [int]$skip=1 ) {
  if ( -not (Test-Path $path -PathType Leaf) ) {
    throw "invalid filename"
  }

  ls $path |
    % { iex "`${$($_.fullname)} = `${$($_.fullname)} | select -skip $skip" }
}

I would like to extend nice answer of Jerome Dalbert. I found very easy to write your own annotation validators in JSR-303 way. You are not limited to have "one field" validation. You can create your own annotation on type level and have complex validation (see examples below). I prefer this way because I don't need mix different types of validation (Spring and JSR-303) like Jerome do. Also this validators are "Spring aware" so you can use @Inject/@Autowire out of box.

Example of custom object validation:

@Target({ TYPE, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = { YourCustomObjectValidator.class })
public @interface YourCustomObjectValid {

    String message() default "{YourCustomObjectValid.message}";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

public class YourCustomObjectValidator implements ConstraintValidator<YourCustomObjectValid, YourCustomObject> {

    @Override
    public void initialize(YourCustomObjectValid constraintAnnotation) { }

    @Override
    public boolean isValid(YourCustomObject value, ConstraintValidatorContext context) {

        // Validate your complex logic 

        // Mark field with error
        ConstraintViolationBuilder cvb = context.buildConstraintViolationWithTemplate(context.getDefaultConstraintMessageTemplate());
        cvb.addNode(someField).addConstraintViolation();

        return true;
    }
}

@YourCustomObjectValid
public YourCustomObject {
}

Update your gradle version.

Go to your project level build.gradle file and make sure you are using the latest version of gradle.

This problem happens because you are calling fun.cpp instead of fun.hpp. So c++ compiler finds func.cpp definition twice and throws this error.

Change line 3 of your main.cpp file, from #include "fun.cpp" to #include "fun.hpp" .

For all those who lost heart trying to set a default DATETIME value in MySQL, I know exactly how you feel/felt. So here it is:

`ALTER TABLE  `table_name` CHANGE `column_name` DATETIME NOT NULL DEFAULT 0

Carefully observe that I haven't added single quotes/double quotes around the 0.

Important update:

This answer was posted long back. Back then, it worked on my (probably latest) installation of MySQL and I felt like sharing it. Please read the comments below before you decide to use this solution now.

Given a radius length r and an angle t in radians and a circle's center (h,k), you can calculate the coordinates of a point on the circumference as follows (this is pseudo-code, you'll have to adapt it to your language):

float x = r*cos(t) + h;
float y = r*sin(t) + k;

You could find the difference between dates in columns in a data frame by using the function difftime as follows:

df$diff_in_days<- difftime(df$datevar1 ,df$datevar2 , units = c("days"))

With Boost:

boost::array<char, 10> testfunc()
{
    boost::array<char, 10> str;

    return str;
}

A normal char[10] (or any other array) can't be returned from a function.

One consideration is that FTP can use non-standard ports, which can make getting though firewalls difficult (especially if you're using SSL). HTTP is typically on a known port, so this is rarely a problem.

If you do decide to use FTP, make sure you read about Active and Passive FTP.

In terms of performance, at the end of the day they're both spewing files directly down TCP connections so should be about the same.

Use this example

System.Globalization.CultureInfo culInfo = new System.Globalization.CultureInfo("en-GB",true);

decimal currency_usd = decimal.Parse(GetRateFromCbrf("usd"),culInfo);
decimal currency_eur = decimal.Parse(GetRateFromCbrf("eur"), culInfo);

A different, PCL-friendly approach would be to use an MSBuild inline task to substitute the build time into a string that is returned by a property on the app. We are using this approach successfully in an app that has Xamarin.Forms, Xamarin.Android, and Xamarin.iOS projects.

EDIT:

Simplified by moving all of the logic into the SetBuildDate.targets file, and using Regex instead of simple string replace so that the file can be modified by each build without a "reset".

The MSBuild inline task definition (saved in a SetBuildDate.targets file local to the Xamarin.Forms project for this example):

<Project xmlns='http://schemas.microsoft.com/developer/msbuild/2003' ToolsVersion="12.0">

  <UsingTask TaskName="SetBuildDate" TaskFactory="CodeTaskFactory" 
    AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v12.0.dll">
    <ParameterGroup>
      <FilePath ParameterType="System.String" Required="true" />
    </ParameterGroup>
    <Task>
      <Code Type="Fragment" Language="cs"><![CDATA[

        DateTime now = DateTime.UtcNow;
        string buildDate = now.ToString("F");
        string replacement = string.Format("BuildDate => \"{0}\"", buildDate);
        string pattern = @"BuildDate => ""([^""]*)""";
        string content = File.ReadAllText(FilePath);
        System.Text.RegularExpressions.Regex rgx = new System.Text.RegularExpressions.Regex(pattern);
        content = rgx.Replace(content, replacement);
        File.WriteAllText(FilePath, content);
        File.SetLastWriteTimeUtc(FilePath, now);

   ]]></Code>
    </Task>
  </UsingTask>

</Project>

Invoking the above inline task in the Xamarin.Forms csproj file in target BeforeBuild:

  <!-- To modify your build process, add your task inside one of the targets below and uncomment it. 
       Other similar extension points exist, see Microsoft.Common.targets.  -->
  <Import Project="SetBuildDate.targets" />
  <Target Name="BeforeBuild">
    <SetBuildDate FilePath="$(MSBuildProjectDirectory)\BuildMetadata.cs" />
  </Target>

The FilePath property is set to a BuildMetadata.cs file in the Xamarin.Forms project that contains a simple class with a string property BuildDate, into which the build time will be substituted:

public class BuildMetadata
{
    public static string BuildDate => "This can be any arbitrary string";
}

Add this file BuildMetadata.cs to project. It will be modified by every build, but in a manner that allows repeated builds (repeated replacements), so you may include or omit it in source control as desired.

This might work for you:

sed 'y/\\/\//'

Here you go:

div{
    display: none;
}

document.querySelector("button").addEventListener("click", function(){
    document.querySelector("div").style.display = "block";
});

<div>blah blah blah</div>
<button>Show</button>

            super.paintComponent(g);
            g.setColor(Color.red);
            g.fillRect(margin, margin, dim.width - margin * 2, dim.height - margin * 2);
        }
    }
}

This isn't appropriate in all situations but you can conditionally return false inside the component itself if a certain criteria is or isn't met.

It doesn't unmount the component, but it removes all rendered content. This would only be bad, in my mind, if you have event listeners in the component that should be removed when the component is no longer needed.

import React, { Component } from 'react';

export default class MyComponent extends Component {
    constructor(props) {
        super(props);

        this.state = {
            hideComponent: false
        }
    }

    closeThis = () => {
        this.setState(prevState => ({
            hideComponent: !prevState.hideComponent
        })
    });

    render() {
        if (this.state.hideComponent === true) {return false;}

        return (
            <div className={`content`} onClick={() => this.closeThis}>
                YOUR CODE HERE
            </div>
        );
    }
}

For a multi-threaded implementation tuned for Intel processors I'd check out Intel's MKL library. It's not free, but it's afforable (less than $100) and blazing fast - but you'd need to call it's C dll's via P/Invokes. The Exocortex project stopped development 6 years ago, so I'd be careful using it if this is an important project.

In a function:

a += 1

will be interpreted by the compiler as assign to a => Create local variable a, which is not what you want. It will probably fail with a a not initialized error since the (local) a has indeed not been initialized:

>>> a = 1
>>> def f():
...     a += 1
... 
>>> f()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in f
UnboundLocalError: local variable 'a' referenced before assignment

You might get what you want with the (very frowned upon, and for good reasons) global keyword, like so:

>>> def f():
...     global a
...     a += 1
... 
>>> a
1
>>> f()
>>> a
2

In general however, you should avoid using global variables which become extremely quickly out of hand. And this is especially true for multithreaded programs, where you don't have any synchronization mechanism for your thread1 to know when a has been modified. In short: threads are complicated, and you cannot expect to have an intuitive understanding of the order in which events are happening when two (or more) threads work on the same value. The language, compiler, OS, processor... can ALL play a role, and decide to modify the order of operations for speed, practicality or any other reason.

The proper way for this kind of thing is to use Python sharing tools (locks and friends), or better, communicate data via a Queue instead of sharing it, e.g. like this:

from threading import Thread
from queue import Queue
import time

def thread1(threadname, q):
    #read variable "a" modify by thread 2
    while True:
        a = q.get()
        if a is None: return # Poison pill
        print a

def thread2(threadname, q):
    a = 0
    for _ in xrange(10):
        a += 1
        q.put(a)
        time.sleep(1)
    q.put(None) # Poison pill

queue = Queue()
thread1 = Thread( target=thread1, args=("Thread-1", queue) )
thread2 = Thread( target=thread2, args=("Thread-2", queue) )

thread1.start()
thread2.start()
thread1.join()
thread2.join()

I prefer to use array_multisort. See the documentation here.

You can use the following script. It worked for me

The modal itself consists of a main modal container, a header, a body, and a footer. The footer contains the actions, which in this case is the OK button, the header holds the title and the close button, and the body contains the modal content.

 $(function () {
        modalPosition();
        $(window).resize(function () {
            modalPosition();
        });
        $('.openModal').click(function (e) {
            $('.modal, .modal-backdrop').fadeIn('fast');
            e.preventDefault();
        });
        $('.close-modal').click(function (e) {
            $('.modal, .modal-backdrop').fadeOut('fast');
        });
    });
    function modalPosition() {
        var width = $('.modal').width();
        var pageWidth = $(window).width();
        var x = (pageWidth / 2) - (width / 2);
        $('.modal').css({ left: x + "px" });
    }

Refer:- Modal popup using jquery in asp.net

The answer is right in the MYSQL manual itself.

"DELETE FROM `table_name` WHERE `time_col` < ADDDATE(NOW(), INTERVAL -1 HOUR)"

You can use the the click function to trigger the click event on the selected element.

Example:

$( 'selector for your link' ).click ();

You can learn about various selectors in jQuery's documentation.

EDIT: like the commenters below have said; this only works on events attached with jQuery, inline or in the style of "element.onclick". It does not work with addEventListener, and it will not follow the link if no event handlers are defined. You could solve this with something like this:

var linkEl = $( 'link selector' );
if ( linkEl.attr ( 'onclick' ) === undefined ) {
    document.location = linkEl.attr ( 'href' );
} else {
    linkEl.click ();
}

Don't know about addEventListener though.

The procedure name should be in caps while creating procedure in database. You may use small letters for your procedure name while calling from Java class like:

String getDBUSERByUserIdSql = "{call getDBUSERByUserId(?,?,?,?)}";

In database the name of procedure should be:

GETDBUSERBYUSERID    -- (all letters in caps only)

This serves as one of the solutions for this problem.

A solution from Hary https://stackoverflow.com/a/37797575/4252764 works very well. It's simpler, doesn't need so many special factory beans, and support multiple triggers and jobs. Would just add that Quartz job can be made to be generic, with specific jobs implemented as regular Spring beans.

public interface BeanJob {
  void executeBeanJob();
}

public class GenericJob implements Job {

  @Override
  public void execute(JobExecutionContext context) throws JobExecutionException {
    JobDataMap dataMap = context.getMergedJobDataMap();
    ((BeanJob)dataMap.get("beanJob")).executeBeanJob();    
  }

}

@Component
public class RealJob implements BeanJob {
  private SomeService service;

  @Autowired
  public RealJob(SomeService service) {
    this.service = service;
  }

  @Override
  public void executeBeanJob() {
      //do do job with service
  }

}

In MATLAB R2015a or newer, it is no longer necessary (or advisable from a performance standpoint) to use fspecial followed by imfilter since there is a new function called imgaussfilt that performs this operation in one step and more efficiently.

The basic syntax:

B = imgaussfilt(A,sigma) filters image A with a 2-D Gaussian smoothing kernel with standard deviation specified by sigma.

The size of the filter for a given Gaussian standard deviation (sigam) is chosen automatically, but can also be specified manually:

B = imgaussfilt(A,sigma,'FilterSize',[3 3]);

The default is 2*ceil(2*sigma)+1.

Additional features of imgaussfilter are ability to operate on gpuArrays, filtering in frequency or spacial domain, and advanced image padding options. It looks a lot like IPP... hmmm. Plus, there's a 3D version called imgaussfilt3.

I've tried many times.

And at last I just put autoindex on; in http but outside of server, and it's OK.

Adding to olliej's answer, you can convert from an int back to a string with NSNumber's stringValue:

[[NSNumber numberWithInt:myInt] stringValue]

stringValue on an NSNumber invokes descriptionWithLocale:nil, giving you a localized string representation of value. I'm not sure if [NSString stringWithFormat:@"%d",myInt] will give you a properly localized reprsentation of myInt.

I know this does not answer your question, but why don't you use a date handling routine to check if it's a valid date? Even if you modify the regexp with a negative lookahead assertion like (?!31/0?2) (ie, do not match 31/2 or 31/02) you'll still have the problem of accepting 29 02 on non leap years and about a single separator date format.

The problem is not easy if you want to really validate a date, check this forum thread.

For an example or a better way, in C#, check this link

If you are using another platform/language, let us know

Python (until version 3) supports "old-style" and new-style classes. New-style classes are derived from object and are what you are using, and invoke their base class through super(), e.g.

class X(object):
  def __init__(self, x):
    pass

  def doit(self, bar):
    pass

class Y(X):
  def __init__(self):
    super(Y, self).__init__(123)

  def doit(self, foo):
    return super(Y, self).doit(foo)

Because python knows about old- and new-style classes, there are different ways to invoke a base method, which is why you've found multiple ways of doing so.

For completeness sake, old-style classes call base methods explicitly using the base class, i.e.

def doit(self, foo):
  return X.doit(self, foo)

But since you shouldn't be using old-style anymore, I wouldn't care about this too much.

Python 3 only knows about new-style classes (no matter if you derive from object or not).

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

4GB's is the maximum size your iOS app can be.

As of January 26, 2017

App Size for iOS (& tvOS) only

Your app’s total uncompressed size must be less than 4GB. Each Mach-O executable file (for example, app_name.app/app_name) must not exceed these limits:

• For apps whose MinimumOSVersion is less than 7.0: maximum of 80 MB for the total of all __TEXT sections in the binary.
• For apps whose MinimumOSVersion is 7.x through 8.x: maximum of 60 MB per slice for the __TEXT section of each architecture slice in the binary.
• For apps whose MinimumOSVersion is 9.0 or greater: maximum of 500 MB for the total of all __TEXT sections in the binary.

However, consider download times when determining your app’s size. Minimize the file’s size as much as possible, keeping in mind that there is a 100 MB limit for over-the-air downloads.

This information can be found at iTunes Connect Developer Guide: Submitting the App to App Review.

A different installation of ruby should be used. I use rbenv for that purpose.

# install your version of ruby
$ rbenv install 2.0.0-p247

# modify .ruby_version on current directory
$ rbenv local 2.0.0-p247

# proceed installing gems
$ gem install bundler

Disclamer: I am not a ruby person. This worked for me and if you are a ruby expert and see things to change in this answer, please, go ahead or comment!

I would strongly suggest you start using jQuery. Your code would look like:

$(function() {
    $('form[name="myform"]').submit(function(e) {
        var username = $('form[name="myform"] input[name="username"]').val();
        if ( username == '') {
            e.preventDefault();
            $('#errors').text('*Please enter a username*');
        }
    });
});

If anyone else comes across this and the accepted answer doesn't work (it didn't for me), check to see if you need to specify a port other than 80. In my case, I was running a rails server at localhost:3000 and was just using curl http://localhost, which was hitting port 80.

Changing the command to curl http://localhost:3000 is what worked in my case.

I think your question is, "why am I getting one more line than there is in the file?"

Imagine a file:

line 1
line 2
line 3

The file may be represented in ASCII like this:

line 1\nline 2\nline 3\n

(Where \n is byte 0x10.)

Now let's see what happens before and after each getline call:

Before 1: line 1\nline 2\nline 3\n
  Stream: ^
After 1:  line 1\nline 2\nline 3\n
  Stream:         ^

Before 2: line 1\nline 2\nline 3\n
  Stream:         ^
After 2:  line 1\nline 2\nline 3\n
  Stream:                 ^

Before 2: line 1\nline 2\nline 3\n
  Stream:                 ^
After 2:  line 1\nline 2\nline 3\n
  Stream:                         ^

Now, you'd think the stream would mark eof to indicate the end of the file, right? Nope! This is because getline sets eof if the end-of-file marker is reached "during it's operation". Because getline terminates when it reaches \n, the end-of-file marker isn't read, and eof isn't flagged. Thus, myfile.eof() returns false, and the loop goes through another iteration:

Before 3: line 1\nline 2\nline 3\n
  Stream:                         ^
After 3:  line 1\nline 2\nline 3\n
  Stream:                         ^ EOF

How do you fix this? Instead of checking for eof(), see if .peek() returns EOF:

while(myfile.peek() != EOF){
    getline ...

You can also check the return value of getline (implicitly casting to bool):

while(getline(myfile,line)){
    cout<< ...

Create directory "bin" in

D:\sqldeveloper\jdk\ Copy

msvcr100.dll from

D:\sqldeveloper\jdk\jre\bin to

D:\sqldeveloper\jdk\bin

sys.exit() will do exactly what you want.

import sys
sys.exit("Error message")

Also note that the class context when initializing can create that exception. If you have an object which is coded as INPROC_SERVER but you try to CoCreateInstance as CLSCTX_LOCAL_SERVER, you will also get that error.

You need to ensure the object is registered and the CoCreateInstance is creating an instance with the correct class context.

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

You can use the below effect to animate, you can change the values as per your requirements

$("#myElem").fadeIn('slow').animate({opacity: 1.0}, 1500).effect("pulsate", { times: 2 }, 800).fadeOut('slow'); 

This is what worked for me on ubuntu curl -L https://www.npmjs.com/install.sh | sh

SMS Push uses SMS as a carrier, WAP uses download via WAP.

You may see if you are not loading jQuery twice somehow. Especially after your plugin JavaScript file loaded.

I has the same error and found that one of my external PHP files was loading jQuery again.

You get the question-mark-diamond characters when your textfile uses high-ANSI encoding -- meaning it uses characters between 127 and 255. Those characters have the eighth (i.e. the most significant) bit set. When ASP.NET reads the textfile it assumes UTF-8 encoding, and that most significant bit has a special meaning.

You must force ASP.NET to interpret the textfile as high-ANSI encoding, by telling it the codepage is 1252:

String textFilePhysicalPath = System.Web.HttpContext.Current.Server.MapPath("~/textfiles/MyInputFile.txt");
String contents = File.ReadAllText(textFilePhysicalPath, System.Text.Encoding.GetEncoding(1252));
lblContents.Text = contents.Replace("\n", "<br />");  // change linebreaks to HTML

It's enough to just use the css property width to do so.

Here is an example:

<style type="text/css">;
    td {
        width:25%;
        height:100%;
        float:left;
    }
</style>

Open up your git bash and type

echo $HOME

This shall be the same folder as you get when you open your command window (cmd) and type

echo %USERPROFILE%

And – of course – the .ssh folder shall be present on THAT directory.

For your literal example you'd want to use the adjacent selector (+).

h4 + p {color:red}//any <p> that is immediately preceded by an <h4>

<h4>Some text</h4>
<p>I'm red</p>
<p>I'm not</p>

However, if you wanted to select all successive paragraphs, you'd need to use the general sibling selector (~).

h4 ~ p {color:red}//any <p> that has the same parent as, and comes after an <h4>

<h4>Some text</h4>
<p>I'm red</p>
<p>I am too</p>

It's known to be buggy in IE 7+ unfortunately.

The jQuery API documentation lists live() as deprecated as of version 1.7 and removed as of version 1.9: link.

version deprecated: 1.7, removed: 1.9

Furthermore it states:

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live()

The easiest solution is to create 3 divs. One that will contain the other 2, the one with transparent background and the one with content. Make the first div's position relative and set the one with transparent background to negative z-index, then adjust the position of the content to fit over the transparent background. This way you won't have issues with absolute positioning.

Actually, jQuery has a built in trim function:

 var emailAdd = jQuery.trim($(this).text());

See here for details.

If you want a default value and don't want to build lookup maps, you can create a static method to handle that. This example also handles lookups where the expected name would start with a number.

    public static final Verbosity lookup(String name) {
        return lookup(name, null);
    }

    public static final Verbosity lookup(String name, Verbosity dflt) {
        if (StringUtils.isBlank(name)) {
            return dflt;
        }
        if (name.matches("^\\d.*")) {
            name = "_"+name;
        }
        try {
            return Verbosity.valueOf(name);
        } catch (IllegalArgumentException e) {
            return dflt;
        }
    }

If you need it on a secondary value, you would just build the lookup map first like in some of the other answers.

The connect router has now been removed (https://github.com/senchalabs/connect/issues/262), the author stating that you should use a framework on top of connect (like Express) for routing.

Express currently treats app.get("/foo*") as app.get(/\/foo(.*)/), removing the need for two separate routes. This is in contrast to the previous answer (referring to the now removed connect router) which stated that "* in a path is replaced with .+".

Update: Express now uses the "path-to-regexp" module (since Express 4.0.0) which maintains the same behavior in the version currently referenced. It's unclear to me whether the latest version of that module keeps the behavior, but for now this answer stands.

For Data access you can use OData. Here is a demo where Scott Hanselman creates an OData front end to StackOverflow database in 30 minutes, with XML and JSON access: Creating an OData API for StackOverflow including XML and JSON in 30 minutes.

For administrative access, like phpMyAdmin package, there is no well established one. You may give a try to IIS Database Manager.

If you are restoring the folder don't forget to chown the files to mysql:mysql

chown -R mysql:mysql /var/lib/mysql-data

otherwise you will get errors when trying to drop a database or add new column etc..

In general, the key to avoiding an explicit loop would be to join (merge) 2 instances of the dataframe on rowindex-1==rowindex.

Then you would have a big dataframe containing rows of r and r-1, from where you could do a df.apply() function.

However the overhead of creating the large dataset may offset the benefits of parallel processing...

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

don't give this in file input value="123".

Looks like you are out of stack memory. You may want to increase it as Davide stated. To do it in python code, you would need to run your "main()" using threading:

def main():
    pass # write your code here

sys.setrecursionlimit(2097152)    # adjust numbers
threading.stack_size(134217728)   # for your needs

main_thread = threading.Thread(target=main)
main_thread.start()
main_thread.join()

Learning to program for the first time is kind of like learning a foreign language. You will easily be able to recreate the phrases you are taught, but you will lack the understanding of the context for why it is done that way, and will thus be unable to solve new problems effectively. It simply takes time.

If you're a first-time programmer, I really can't recommend Java. Python would be much better (disclaimer: Python fan-boy, but for good reasons).

However, I don't think a beginner could do much better than Head First Java

in python 2.6 use string enclosed inside quotation " and apostrophe ' marks. Also a change single / to double //. Your working example will look like this:

import os
os.system("'C://Documents and Settings//flow_model//flow.exe'") 

Also You can use any parameters if Your program ingest them.

os.system('C://"Program Files (x86)"//Maxima-gcl-5.37.3//gnuplot//bin//gnuplot -e "plot [-10:10] sin(x),atan(x),cos(atan(x)); pause mouse"')

finally You can use string variable, as an example is plotting using gnuplot directly from python:

this_program='C://"Program Files (x86)"//Maxima-gcl-5.37.3//gnuplot//bin//gnuplot'

this_par='-e "set polar; plot [-2*pi:2*pi] [-3:3] [-3:3] t*sin(t); pause -1"'
os.system(this_program+" "+this_par)

I'm not really sure if I got your question right. Maybe something like

public class CommentsController : Controller
{
    [HttpPost]
    public ActionResult WriteComment(CommentModel comment)
    {
        // Do the basic model validation and other stuff
        try
        {
            if (ModelState.IsValid )
            {
                 // Insert the model to database like:
                 db.Comments.Add(comment);
                 db.SaveChanges();

                 // Pass the comment's article id to the read action
                 return RedirectToAction("Read", "Articles", new {id = comment.ArticleID});
            }
        }
        catch ( Exception e )
        {
             throw e;
        }
        // Something went wrong
        return View(comment);

    }
}


public class ArticlesController : Controller
{
    // id is the id of the article
    public ActionResult Read(int id)
    {
        // Get the article from database by id
        var model = db.Articles.Find(id);
        // Return the view
        return View(model);
    }
}

If you want to enable general error logs and slow query error log in the table instead of file

To start logging in table instead of file:

set global log_output = “TABLE”;

To enable general and slow query log:

set global general_log = 1;
set global slow_query_log = 1;

To view the logs:

select * from mysql.slow_log;
select * from mysql.general_log;

MySQL Workbench

If you want to avoid writing sql, you can also do it in MySQL Workbench by right clicking on the table, choose "Alter Table ..." in the menu.

When the table structure view opens, go to tab "Options" (on the lower bottom of the view), and set "Auto Increment" field to the value of the next autoincrement number.

Don't forget to hit "Apply" when you are done with all changes.

PhpMyAdmin:

If you are using phpMyAdmin, you can click on the table in the lefthand navigation, go to the tab "Operations" and under Table Options change the AUTO_INCREMENT value and click OK.

You cannot session_start(); when your buffer has already been partly sent.

This mean, if your script already sent informations (something you want, or an error report) to the client, session_start() will fail.

Exception is a checked exception class. Therefore, any code that calls a method that declares that it throws Exception must handle or declare it.

Use the code below with the new clear cache commands: php artisan cache clear

//Clear route cache:
 Route::get('/route-cache', function() {
     // EDIT - the linked article uses route:cache, it should be route:clear
     // $exitCode = Artisan::call('route:cache');
     $exitCode = Artisan::call('route:clear');
     return 'Routes cache cleared';
 });

 //Clear config cache:
 Route::get('/config-cache', function() {
     $exitCode = Artisan::call('config:clear');
     return 'Config cache cleared';
 }); 

// Clear application cache:
 Route::get('/clear-cache', function() {
     $exitCode = Artisan::call('cache:clear');
     return 'Application cache cleared';
 });

 // Clear view cache:
 Route::get('/view-clear', function() {
     $exitCode = Artisan::call('view:clear');
     return 'View cache cleared';
 });

I use ConEmu (strongly recommended on Windows) where I have a task for starting Git Bash like

Note the button "Startup dir..." in the bottom. It adds a -new_console:d:<path> to the startup command of the Git Bash. Make it point to wherever you like

Here is some good overview of .NET impersonation concepts.

• Michiel van Otegem: WindowsImpersonationContext made easy
• WindowsIdentity.Impersonate Method (check out the code samples)

Basically you will be leveraging these classes that are out of the box in the .NET framework:

• WindowsImpersonationContext
• WindowsIdentity

The code can often get lengthy though and that is why you see many examples like the one you reference that try to simplify the process.

In my case, display: block was breaking the design as intended.

The max-width property just saved me.

and for styling, you can use text-overflow: ellipsis as well.

my code was

max-width: 255px
overflow:hidden

Surprised nobody brought this one up:

# To remove last n rows
df.head(-n)

# To remove first n rows
df.tail(-n)

Running a speed test on a DataFrame of 1000 rows shows that slicing and head/tail are ~6 times faster than using drop:

>>> %timeit df[:-1]
125 µs ± 132 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

>>> %timeit df.head(-1)
129 µs ± 1.18 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)

>>> %timeit df.drop(df.tail(1).index)
751 µs ± 20.4 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Neither restclient nor REST console support this but curl does.

The HTTP specification says in section 4.3

A message-body MUST NOT be included in a request if the specification of the request method (section 5.1.1) does not allow sending an entity-body in requests.

Section 5.1.1 redirects us to section 9.x for the various methods. None of them explicitly prohibit the inclusion of a message body. However...

Section 5.2 says

The exact resource identified by an Internet request is determined by examining both the Request-URI and the Host header field.

and Section 9.3 says

The GET method means retrieve whatever information (in the form of an entity) is identified by the Request-URI.

Which together suggest that when processing a GET request, a server is not required to examine anything other that the Request-URI and Host header field.

In summary, the HTTP spec doesn't prevent you from sending a message-body with GET but there is sufficient ambiguity that it wouldn't surprise me if it was not supported by all servers.

Use fcron (http://fcron.free.fr/) - gives you granularity in seconds and way better and more feature rich than cron (vixie-cron) and stable too. I used to make stupid things like having about 60 php scripts running on one machine in very stupid settings and it still did its job!

$ git remote remove <name>

ie.

$ git remote remove upstream

that should do the trick

Many (most?) SQL databases can work with tuples like values so you can just do: SELECT COUNT(DISTINCT (DocumentId, DocumentSessionId)) FROM DocumentOutputItems; If your database doesn't support this, it can be simulated as per @oncel-umut-turer's suggestion of CHECKSUM or other scalar function providing good uniqueness e.g. COUNT(DISTINCT CONCAT(DocumentId, ':', DocumentSessionId)).

A related use of tuples is performing IN queries such as: SELECT * FROM DocumentOutputItems WHERE (DocumentId, DocumentSessionId) in (('a', '1'), ('b', '2'));

check available Java versions on your Linux system by using update-alternatives command:

 $ sudo update-alternatives --display java

Now that there are suitable candidates to change to, you can switch the default Java version among available Java JREs by running the following command:

 $ sudo update-alternatives --config java

When prompted, select the Java version you would like to use.1 or 2 or 3 or etc..

Now you can verify the default Java version changed as follows.

 $ java -version

...
WHERE ...
      AND (@Location is null OR (Location like '%' + @Location + '%'))
      AND (@Date is null OR (Date = @Date))

This way it is more obvious the parameter is not used when null.

Here's the mysql reference for cursors. So I'm guessing it's something like this:

  DECLARE done INT DEFAULT 0;
  DECLARE products_id INT;
  DECLARE result varchar(4000);
  DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

  OPEN cur1;

  REPEAT
    FETCH cur1 INTO products_id;
    IF NOT done THEN
      CALL generate_parameter_list(@product_id, @result);
      SET param = param + "," + result; -- not sure on this syntax
    END IF;
  UNTIL done END REPEAT;

  CLOSE cur1;

  -- now trim off the trailing , if desired
