Programs & Examples On #Fflush

Flushing the output buffers:

printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is

or

fprintf(fd, "Buffered, will be flushed");
fflush(fd);  //Prints to a file

Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf() it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.

Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf(), so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.

I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf() is an expensive operation (which is why it doesn't by default flush the buffer).

As far as flushing the input buffer (stdin), you should not do that. Flushing stdin is undefined behavior according to the C11 standard §7.21.5.2 part 2:

If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.

On some systems, Linux being one as you can see in the man page for fflush(), there's a defined behavior but it's system dependent so your code will not be portable.

Now if you're worried about garbage "stuck" in the input buffer you can use fpurge() on that. See here for more on fflush() and fpurge()

so if you have a table with a row like:

firstname lastname
Bill      smith

you can do something like

select firstname + ' ' + lastname from thetable

and you will get "Bill Smith"

IMO, this is the best way if you have filenames like name.name.name.ext (ugly, but it sometimes happens):

$ext     = explode('.', $filename); // Explode the string
$my_ext  = end($ext); // Get the last entry of the array

echo $my_ext;

I only just noticed this question, and wanted to add my $.02 to this.

In case of Java, this is not actually an option. The "unreachable code" error doesn't come from the fact that JVM developers thought to protect developers from anything, or be extra vigilant, but from the requirements of the JVM specification.

Both Java compiler, and JVM, use what is called "stack maps" - a definite information about all of the items on the stack, as allocated for the current method. The type of each and every slot of the stack must be known, so that a JVM instruction doesn't mistreat item of one type for another type. This is mostly important for preventing having a numeric value ever being used as a pointer. It's possible, using Java assembly, to try to push/store a number, but then pop/load an object reference. However, JVM will reject this code during class validation,- that is when stack maps are being created and tested for consistency.

To verify the stack maps, the VM has to walk through all the code paths that exist in a method, and make sure that no matter which code path will ever be executed, the stack data for every instruction agrees with what any previous code has pushed/stored in the stack. So, in simple case of:

Object a;
if (something) { a = new Object(); } else { a = new String(); }
System.out.println(a);

at line 3, JVM will check that both branches of 'if' have only stored into a (which is just local var#0) something that is compatible with Object (since that's how code from line 3 and on will treat local var#0).

When compiler gets to an unreachable code, it doesn't quite know what state the stack might be at that point, so it can't verify its state. It can't quite compile the code anymore at that point, as it can't keep track of local variables either, so instead of leaving this ambiguity in the class file, it produces a fatal error.

Of course a simple condition like if (1<2) will fool it, but it's not really fooling - it's giving it a potential branch that can lead to the code, and at least both the compiler and the VM can determine, how the stack items can be used from there on.

P.S. I don't know what .NET does in this case, but I believe it will fail compilation as well. This normally will not be a problem for any machine code compilers (C, C++, Obj-C, etc.)

I just hide() the tinymce and submit form, the changed value of textarea missing. So I added this:

$("textarea[id='id_answer']").change(function(){
    var editor_id = $(this).attr('id');
    var editor = tinymce.get(editor_id);
    editor.setContent($(this).val()).save();
});

It works for me.

I used the code from the most upvoted answer:

startActivityForResult(new Intent(android.provider.Settings.ACTION_SETTINGS), 0);

It opens the device settings in the same window, thus got the users of my android application (finnmglas/Launcher) for android stuck in there.

The answer for 2020 and beyond (in Kotlin):

startActivity(Intent(Settings.ACTION_SETTINGS))

It works in my app, should also be working in yours without any unwanted consequences.

Disable all indexes (including the pk, which will disable all fks), then reenable the pks.

DECLARE @sql AS NVARCHAR(max)=''
select @sql = @sql +
    'ALTER INDEX ALL ON [' + t.[name] + '] DISABLE;'+CHAR(13)
from  
    sys.tables t
where type='u'

select @sql = @sql +
    'ALTER INDEX ' + i.[name] + ' ON [' + t.[name] + '] REBUILD;'+CHAR(13)
from  
    sys.key_constraints i
join
    sys.tables t on i.parent_object_id=t.object_id
where
    i.type='PK'


exec dbo.sp_executesql @sql;
go

[Do your data load]

Then bring everything back to life...

Here is a complete example for navigating valid URL on a new tab with focused.

HTML:

<div class="panel">
  <p>
    Enter Url: 
    <input type="text" id="txturl" name="txturl" size="30" class="weburl" />
    &nbsp;&nbsp;    
    <input type="button" id="btnopen"  value="Open Url in New Tab" onclick="openURL();"/>
  </p>
</div>

CSS:

.panel{
  font-size:14px;
}
.panel input{
  border:1px solid #333;
}

JAVASCRIPT:

function isValidURL(url) {
    var RegExp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;

    if (RegExp.test(url)) {
        return true;
    } else {
        return false;
    }
}

function openURL() {
    var url = document.getElementById("txturl").value.trim();
    if (isValidURL(url)) {
        var myWindow = window.open(url, '_blank');
        myWindow.focus();
        document.getElementById("txturl").value = '';
    } else {
        alert("Please enter valid URL..!");
        return false;
    }
}

I want to add a point that you can also (and should if what you are writing is complex) add a test variable to rollback if you are in test mode. Then you can execute the whole thing at once. Often I also add code to see the before and after results of various operations especially if it is a complex script.

Example below:

USE AdventureWorks;
GO
DECLARE @TEST INT = 1--1 is test mode, use zero when you are ready to execute
BEGIN TRANSACTION;

BEGIN TRY
     IF @TEST= 1
        BEGIN
            SELECT *FROM Production.Product
                WHERE ProductID = 980;
        END    
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;

     IF @TEST= 1
        BEGIN
            SELECT *FROM Production.Product
                WHERE ProductID = 980;
            IF @@TRANCOUNT > 0
                ROLLBACK TRANSACTION;
        END    
END TRY

BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0 AND @TEST = 0
    COMMIT TRANSACTION;
GO

Using java 8 Stream API could simplify your job.

public static boolean inArray(int[] array, int check) {
    return Stream.of(array).anyMatch(i -> i == check);
}

It's just you have the overhead of creating a new Stream from Array, but this gives exposure to use other Stream API. In your case you may not want to create new method for one-line operation, unless you wish to use this as utility. Hope this helps!

picmate's answer is right. on windows the main DB folder location is (at least on my installation)

C:\PostgreSQL\9.2\data\base\

and not in program files.

his 2 scripts, will give you the exact directory/file(s) you need:

SELECT oid from pg_database WHERE datname = <database_name>;
SELECT relname, relfilenode FROM pg_class WHERE relname = <table_name>; 

mine is in datname 16393 and relfilenode 41603

Well, found a solution to my problem; Updating all rows using a SQL query and a SQL Task in SSIS Like Below. May help others if they face same challenge in future.

1. PYTHONPATH is an environment variable
2. Yes (see https://unix.stackexchange.com/questions/24802/on-which-unix-distributions-is-python-installed-as-part-of-the-default-install)
3. /usr/lib/python2.7 on Ubuntu
4. you shouldn't install packages manually. Instead, use pip. When a package isn't in pip, it usually has a setuptools setup script which will install the package into the proper location (see point 3).
5. if you use pip or setuptools, then you don't need to set PYTHONPATH explicitly

If you look at the instructions for pyopengl, you'll see that they are consistent with points 4 and 5.

You can try with mentioning "Accept: application/json" in your rest client header as well, if you are expecting your object as JSON in response.

Best one

String str_date=month+"-"+day+"-"+yr;
DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy");
Date date = (Date)formatter.parse(str_date); 
long output=date.getTime()/1000L;
String str=Long.toString(output);
long timestamp = Long.parseLong(str) * 1000;

This happens when your result is not a result (but a "false" instead). You should change this line

$sql = 'SELECT * FROM $usertable WHERE PartNumber = $partid';

to this:

$sql = "SELECT * FROM $usertable WHERE PartNumber = $partid";

because the " can interprete $variables while ' cannot.

Works fine with integers (numbers), for strings you need to put the $variable in single quotes, like

$sql = "SELECT * FROM $usertable WHERE PartNumber = '$partid' ";

If you want / have to work with single quotes, then php CAN NOT interprete the variables, you will have to do it like this:

 $sql = 'SELECT * FROM '.$usertable.' WHERE string_column = "'.$string.'" AND integer_column = '.$number.';

Add this

node_modules/

to .gitignore file to ignore all directories called node_modules in current folder and any subfolders

You don't actually need to run a command from an xterm session, you can run it directly:

String[] arguments = new String[] {"/path/to/executable", "arg0", "arg1", "etc"};
Process proc = new ProcessBuilder(arguments).start();

If the process responds interactively to the input stream, and you want to inject values, then do what you did before:

OutputStream out = proc.getOutputStream();  
out.write("command\n");  
out.flush();

Don't forget the '\n' at the end though as most apps will use it to identify the end of a single command's input.

For many it's a permission issue, but for me it turns out the error was brought about by a mistake in the form I was trying to submit. To be specific i had accidentally put ">" sign after the value of "action". So I would suggest you take a second look at your code

This worked for me, but I used it as start. powershell outputs, waiting for service to finshing starting a few times then finishes and then a get-service on the remote server shows the service started.

You might have old invalid username/password cached in your browser. Try clearing them and check again.

If you are using IE and somesite.com is in your Intranet security zone, IE may be sending your windows credentials automatically.

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

Ref denotes whether the function can get its hands on the object itself, or only on its value.

Passing by reference is not bound to a language; it's a parameter binding strategy next to pass-by-value, pass by name, pass by need etc...

A sidenote: the class name TestRef is a hideously bad choice in this context ;).

The documentation says

The output format of the date/time types can be set to one of the four styles ISO 8601, SQL (Ingres), traditional POSTGRES (Unix date format), or German. The default is the ISO format.

So this particular format can be controlled with postgres date time output, eg:

t=# select now();
              now
-------------------------------
 2017-11-29 09:15:25.348342+00
(1 row)

t=# set datestyle to DMY, SQL;
SET
t=# select now();
              now
-------------------------------
 29/11/2017 09:15:31.28477 UTC
(1 row)

t=# select now()::date;
    now
------------
 29/11/2017
(1 row)

Mind that as @Craig mentioned in his answer, changing datestyle will also (and in first turn) change the way postgres parses date.

All appender names must be reflected in the root section.
In your case the appender name is EventLogAppender but in the <root> <appender-ref .. section it is named as ConsoleAppender. They need to match.

You can add multiple appenders to your log config but you need to register each of them in the <root> section.

<appender-ref ref="ConsoleAppender" />
<appender-ref ref="EventLogAppender" />

You can also refer to the apache documentation on configuring log4net.

Use break:

while (true) {
    ....
    if (obj == null) {
        break;
    }
    ....
}

However, if your code looks exactly like you have specified you can use a normal while loop and change the condition to obj != null:

while (obj != null) {
    ....
}

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Test {
    public static void main(String[] args) {
        Pattern pattern = Pattern.compile(".*'([^']*)'.*");
        String mydata = "some string with 'the data i want' inside";

        Matcher matcher = pattern.matcher(mydata);
        if(matcher.matches()) {
            System.out.println(matcher.group(1));
        }

    }
}

Here's some nice and clean syntax on Angular's NgIf and using the else statement. In short, you will declare an ElementRef on an element and then reference it in the else block:

<div *ngIf="isLoggedIn; else loggedOut">
   Welcome back, friend.
</div>

<ng-template #loggedOut>
  Please friend, login.
</ng-template>

I've taken this example from NgIf, Else, Then which I found to be really well explained.

It also demonstrates using the <ng-template> syntax:

<ng-template [ngIf]="isLoggedIn" [ngIfElse]="loggedOut">
  <div>
    Welcome back, friend.
  </div>
</ng-template>

<ng-template #loggedOut>
  <div>
    Please friend, login.
  </div>
</ng-template>

And also using <ng-container> if that's what you're after:

<ng-container
  *ngIf="isLoggedIn; then loggedIn; else loggedOut">
</ng-container>

<ng-template #loggedIn>
  <div>
    Welcome back, friend.
  </div>
</ng-template>
<ng-template #loggedOut>
  <div>
    Please friend, login.
  </div>
</ng-template>

Source is taken from here on Angular's NgIf and Else syntax. I hope this helped! Enjoy.

You could run your JUnit test from a main method and repeat it so many times you need:

package tests;

import static org.junit.Assert.*;

import org.junit.Test;
import org.junit.runner.Result;

public class RepeatedTest {

    @Test
    public void test() {
        fail("Not yet implemented");
    }

    public static void main(String args[]) {

        boolean runForever = true;

        while (runForever) {
            Result result = org.junit.runner.JUnitCore.runClasses(RepeatedTest.class);

            if (result.getFailureCount() > 0) {
                runForever = false;
               //Do something with the result object

            }
        }

    }

}

You can also do it without modulus. Just reset your counter when it matches.

if($counter == 2) { // matches every 3 iterations
   echo 'image-file';
   $counter = 0; 
}

I would just like to share the recent predicament I encounter with the RecyclerView. I hope that anyone experiencing the same problem will benefit.

My Project Requirement: So I have a RecyclerView that list some clickable items in my Main Activity (Activity-A). When the Item is clicked a new Activity is shown with the Item Details (Activity-B).

I implemented in the Manifest file the that the Activity-A is the parent of Activity-B, that way, I have a back or home button on the ActionBar of the Activity-B

Problem: Every time I pressed the Back or Home button in the Activity-B ActionBar, the Activity-A goes into the full Activity Life Cycle starting from onCreate()

Even though I implemented an onSaveInstanceState() saving the List of the RecyclerView's Adapter, when Activity-A starts it's lifecycle, the saveInstanceState is always null in the onCreate() method.

Further digging in the internet, I came across the same problem but the person noticed that the Back or Home button below the Anroid device (Default Back/Home button), the Activity-A does not goes into the Activity Life-Cycle.

Solution:

1. I removed the Tag for Parent Activity in the manifest for Activity-B

2. I enabled the home or back button on Activity-B

   Under onCreate() method add this line supportActionBar?.setDisplayHomeAsUpEnabled(true)

3. In the overide fun onOptionsItemSelected() method, I checked for the item.ItemId on which item is clicked based on the id. The Id for the back button is

   android.R.id.home

   Then implement a finish() function call inside the android.R.id.home

   This will end the Activity-B and bring Acitivy-A without going through the entire life-cycle.

For my requirement this is the best solution so far.

     override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_show_project)

    supportActionBar?.title = projectName
    supportActionBar?.setDisplayHomeAsUpEnabled(true)

}


 override fun onOptionsItemSelected(item: MenuItem?): Boolean {

    when(item?.itemId){

        android.R.id.home -> {
            finish()
        }
    }

    return super.onOptionsItemSelected(item)
}

Even if you do not have the pid, you can trigger 'wait;' after triggering all background processes. For. eg. in commandfile.sh-

bteq < input_file1.sql > output_file1.sql &
bteq < input_file2.sql > output_file2.sql &
bteq < input_file3.sql > output_file3.sql &
wait

Then when this is triggered, as -

subprocess.call(['sh', 'commandfile.sh'])
print('all background processes done.')

This will be printed only after all the background processes are done.

I had the same problem. what I did is: 1. clean the target 2. exit the xcode 3. restart xcode 4. rebuild.
and it worked.

Deep deletion nil values from a hash.

      new_hash[k] = deep_remove_nil_values(v) if v.is_a?(Hash)
      new_hash[k] = v unless v.nil?
    end
  end

  # rewrite current hash
  def self.deep_remove_nil_values!(hash)
    hash.each do |k, v|
      deep_remove_nil_values(v) if v.is_a?(Hash)
      hash.delete(k) if v.nil?
    end
  end

In Windows Explorer, just go to the Address Bar at the top (keyboard shortcuts: Alt+D or Ctrl+L) and type powershell or powershell_ise and press Enter. A PowerShell command window opens with the current directory.

All these methods fail to work for me but this method allows you to change it to a color string.

Please note that i found this code from somewhere else on StackOverflow and changed it a little. I have since forgot where i found this code and i can't link it because of that so sorry for that.

But anyway i hope this code helps someone it really did help me.

        var brush = (Brush)converter.ConvertFromString("#FFB6D301");
        ProgressBar.Foreground = brush;
    }

Where the name "ProgressBar" is used replace with your own progress bar name. You can also trigger this event with other arguments just make sure its inside brackets somewhere.

You're trying to connect to localhost:8080 ... is any service running on your localhost and on this port? If not, the connection is refused which cause this error. I would suggest to check if there is anything running on localhost:8080 first.

Actually I am preferring to use NEW_BROKER ,it is working fine on all cases:

ALTER DATABASE [dbname] SET NEW_BROKER WITH ROLLBACK IMMEDIATE;

java.util.Date date = ...
DateTime dateTime = new DateTime(date);

Make sure date isn't null, though, otherwise it acts like new DateTime() - I really don't like that.

This question has been answered but I feel I should also mention another potential cause. This is a direct result of coming across the same error message but for different reasons. If your list/s are empty the operation will not be performed. check your code for indents and typos

Yes you can put the break-point on client side page in Visual studio

First Put the debugger in java-script code and run the page in browser

debugger

After that open your page in browser and view the inspect element you see the following view

You can just substract two date objects.

var d1 = new Date(); //"now"
var d2 = new Date("2011/02/01")  // some date
var diff = Math.abs(d1-d2);  // difference in milliseconds

You could use the CSS calc parameter to calculate the height dynamically like so:

.dynamic-height {_x000D_

Find all your crashes in device locally and fix them at your convenience. Crashes are saved using date and time format easy to track. Plus it also provides API for capture Logged Exceptions using below method.

CrashRepoter.logException(Exception e)

Here is the example of one Object, For your case you have to use JSONArray.

public static final String JSON_STRING="{\"employee\":{\"name\":\"Sachin\",\"salary\":56000}}";  
try{  
   JSONObject emp=(new JSONObject(JSON_STRING)).getJSONObject("employee");  
   String empname=emp.getString("name");  
   int empsalary=emp.getInt("salary");  

   String str="Employee Name:"+empname+"\n"+"Employee Salary:"+empsalary;  
   textView1.setText(str);  

}catch (Exception e) {e.printStackTrace();}  
   //Do when JSON has problem.
}

I don't have time but tried to give an idea. If you still can't do it, then I will help.

I find I have started having this issue with Lion + Xcode 4.2. I have also experienced the issue in Xcode 4.3.

I have tried all the suggestions but none of them have worked other than a full reboot.

Here is how you determine if you require a reboot quickly.

List out all your Zombie processes:

ps -el | grep 'Z'

If you see your app listed as a Zombie process you will need to reboot your machine. The error message states "This generally means that another instance of this process was already running or is hung in the debugger". Well, Xcode is detecting this Zombie process which you can't kill. The only way you can then fix it is with a system reboot. :(

EDIT, 20120823: I have some better knowledge of Zombie processes so I wanted to update this answer. A Zombie process is created when a parent process does not call wait() (wait for process to change state) on a terminating child process. You can't run 'kill' directly on a Zombie process but if you kill the parent process, the zombie child process will be 'reaped' and removed from the process table.

I haven't seen this issue in a long while so haven't inspected to see what the parent process is in this scenario. The alternative to killing the parent process is to reboot your system. :)

For int types use:

int myInteger = 1;
String myString = Integer.toString(myInteger);

For Integer types use:

Integer myIntegerObject = new Integer(1);
String myString = myIntegerObject.toString();

sys.executable is not reliable if working in an embedded python environment. My suggestions is to deduce it from

import os
os.__file__

What you missed here is timezones.

Presumably you've five hours off UTC, so 2013-09-01T11:00:00 local and 2013-09-01T06:00:00Z are the same time.

You need to read the top of the datetime docs, which explain about timezones and "naive" and "aware" objects.

If your original naive datetime was UTC, the way to recover it is to use utcfromtimestamp instead of fromtimestamp.

On the other hand, if your original naive datetime was local, you shouldn't have subtracted a UTC timestamp from it in the first place; use datetime.fromtimestamp(0) instead.

Or, if you had an aware datetime object, you need to either use a local (aware) epoch on both sides, or explicitly convert to and from UTC.

If you have, or can upgrade to, Python 3.3 or later, you can avoid all of these problems by just using the timestamp method instead of trying to figure out how to do it yourself. And even if you don't, you may want to consider borrowing its source code.

(And if you can wait for Python 3.4, it looks like PEP 341 is likely to make it into the final release, which means all of the stuff J.F. Sebastian and I were talking about in the comments should be doable with just the stdlib, and working the same way on both Unix and Windows.)

There can also be a solution by having both float to left.

The best way is to use closures, because the window object gets very, very cluttered with properties.

If you're using GNU find,

find . -mtime 1 -exec cp -t ~/test/ {} +

This works as well as piping the output into xargs while avoiding the pitfalls of doing so (it handles embedded spaces and newlines without having to use find ... -print0 | xargs -0 ...).

To ensure success with a full path use recurse=yes

- name: ensure custom facts directory exists
    file: >
      path=/etc/ansible/facts.d
      recurse=yes
      state=directory

Here's a regex which will grab what's between cow and milk (without leading/trailing space):

srctext = "My cow always gives milk.";
var re = /(.*cow\s+)(.*)(\s+milk.*)/;
var newtext = srctext.replace(re, "$2");

An example: http://jsfiddle.net/entropo/tkP74/

I was only interested for a trigger when a width of an element was changed (I don' care about height), so I created a jquery event that does exactly that, using an invisible iframe element.

$.event.special.widthChanged = {
  remove: function() {
      $(this).children('iframe.width-changed').remove();
  },
  add: function () {
      var elm = $(this);
      var iframe = elm.children('iframe.width-changed');
      if (!iframe.length) {
          iframe = $('<iframe/>').addClass('width-changed').prependTo(this);
      }
      var oldWidth = elm.width();
      function elmResized() {
          var width = elm.width();
          if (oldWidth != width) {
              elm.trigger('widthChanged', [width, oldWidth]);
              oldWidth = width;
          }
      }

      var timer = 0;
      var ielm = iframe[0];
      (ielm.contentWindow || ielm).onresize = function() {
          clearTimeout(timer);
          timer = setTimeout(elmResized, 20);
      };
  }
}

It requires the following css :

iframe.width-changed {
    width: 100%;
    display: block;
    border: 0;
    height: 0;
    margin: 0;
}

You can see it in action here widthChanged fiddle

Try like this:

SELECT cast(round(123.456,2,1) as decimal(18,2)) 

Above answer's holds good.

Just an add-on for anyone who is into async-await rather than promise !!

const findAllFoo = async (req, resp, next) => {
    const pageSize = 10;
    const currentPage = 1;

    try {
        const foos = await FooModel.find() // find all documents
            .skip(pageSize * (currentPage - 1)) // we will not retrieve all records, but will skip first 'n' records
            .limit(pageSize); // will limit/restrict the number of records to display

        const numberOfFoos = await FooModel.countDocuments(); // count the number of records for that model

        resp.setHeader('max-records', numberOfFoos);
        resp.status(200).json(foos);

    } catch (err) {
        resp.status(500).json({
            message: err
        });
    }
};

i tried to train unet on voc data set but because of huge image size, memory finishes. i tried all the above tips, even tried with batch size==1, yet to no improvement. sometimes TensorFlow version also causes the memory issues. try by using

pip install tensorflow-gpu==1.8.0

In some cases (like in my case) you may be trying to delete an image by specifying the image id that has multiple tags that you don't realize exist, some of which may be used by other images. In which case, you may not want to remove the image.

If you have a case of redundant tags as described here, instead of docker rmi <image_id> use docker rmi <repo:tag> on the redundant tag you wish to remove.

Aside from limiting the columns selected to reduce bandwidth and memory:

DataTable t;
t.Columns.Remove("columnName");
t.Columns.RemoveAt(columnIndex);

A global JS variable (object) can be used to pass data between components. Example: Passing data from Ammlogin.vue to Options.vue. In Ammlogin.vue rspData is set to the response from the server. In Options.vue the response from the server is made available via rspData.

index.html:

<script>
    var rspData; // global - transfer data between components
</script>

Ammlogin.vue:

....    
export default {
data: function() {return vueData}, 
methods: {
    login: function(event){
        event.preventDefault(); // otherwise the page is submitted...
        vueData.errortxt = "";
        axios.post('http://vueamm...../actions.php', { action: this.$data.action, user: this.$data.user, password: this.$data.password})
            .then(function (response) {
                vueData.user = '';
                vueData.password = '';
                // activate v-link via JS click...
                // JSON.parse is not needed because it is already an object
                if (response.data.result === "ok") {
                    rspData = response.data; // set global rspData
                    document.getElementById("loginid").click();
                } else {
                    vueData.errortxt = "Felaktig avändare eller lösenord!"
                }
            })
            .catch(function (error) {
                // Wu oh! Something went wrong
                vueData.errortxt = error.message;
            });
    },
....

Options.vue:

<template>
<main-layout>
  <p>Alternativ</p>
  <p>Resultat: {{rspData.result}}</p>
  <p>Meddelande: {{rspData.data}}</p>
  <v-link href='/'>Logga ut</v-link>
</main-layout>
</template>
<script>
 import MainLayout from '../layouts/Main.vue'
 import VLink from '../components/VLink.vue'
 var optData = { rspData: rspData}; // rspData is global
 export default {
   data: function() {return optData},
   components: {
     MainLayout,
     VLink
   }
 }

For lower bound,

lg(n!) = lg(n)+lg(n-1)+...+lg(n/2)+...+lg2+lg1
       >= lg(n/2)+lg(n/2)+...+lg(n/2)+ ((n-1)/2) lg 2 (leave last term lg1(=0); replace first n/2 terms as lg(n/2); replace last (n-1)/2 terms as lg2 which will make cancellation easier later)
       = n/2 lg(n/2) + (n/2) lg 2 - 1/2 lg 2
       = n/2 lg n - (n/2)(lg 2) + n/2 - 1/2
       = n/2 lg n - 1/2

lg(n!) >= (1/2) (n lg n - 1)

Combining both bounds :

1/2 (n lg n - 1) <= lg(n!) <= n lg n

By choosing lower bound constant greater than (1/2) we can compensate for -1 inside the bracket.

Thus lg(n!) = Theta(n lg n)

The basic advantage of using enum class over normal enums is that you may have same enum variables for 2 different enums and still can resolve them(which has been mentioned as type safe by OP)

For eg:

enum class Color1 { red, green, blue };    //this will compile
enum class Color2 { red, green, blue };

enum Color1 { red, green, blue };    //this will not compile 
enum Color2 { red, green, blue };

As for the basic enums, compiler will not be able to distinguish whether red is refering to the type Color1 or Color2 as in hte below statement.

enum Color1 { red, green, blue };   
enum Color2 { red, green, blue };
int x = red;    //Compile time error(which red are you refering to??)

Css Part is:

CSS:

@media (max-width: 767px) {

  // Align text to center.
  .text-xs-center {
    text-align: center;
  } 
}

And the HTML part will be ( this text center work only below 767px width )

HTML:

 <div class="col-xs-12 col-sm-6 text-right text-xs-center">
        <p>
            <a href="#"><i class="fa fa-facebook"></i></a> 
            <a href="#"><i class="fa fa-twitter"></i></a> 
            <a href="#"><i class="fa fa-google-plus"></i></a>
        </p>
 </div>

With my pymongo version: 3.2.2 I had do the following

from bson.objectid import ObjectId
import pymongo

client = pymongo.MongoClient("localhost", 27017)
db = client.mydbname

db.ProductData.update_one({
  '_id': ObjectId(p['_id']['$oid'])
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False)

I used (this is a unix environment) :

export SBT_OPTS="$SBT_OPTS -Dhttp.proxyHost=myproxy-Dhttp.proxyPort=myport"

This did not work for my setup :

export JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=myproxy-Dhttp.proxyPort=myport"

In sbt.sh file :

JAVA_OPTS          environment variable, if unset uses "$java_opts"
SBT_OPTS           environment variable, if unset uses "$default_sbt_opts"

But apparently SBT_OPTS is used instead of JAVA_OPTS

SQL Server does not track licensing. Customers are responsible for tracking the assignment of licenses to servers, following the rules in the Licensing Guide.

Your C++ is showing.

There is no delete in java, and all objects are created on the heap. The JVM has a garbage collector that relies on reference counts.

Once there are no more references to an object, it becomes available for collection by the garbage collector.

myObject = null may not do it; for example:

Foo myObject = new Foo(); // 1 reference
Foo myOtherObject = myObject; // 2 references
myObject = null; // 1 reference

All this does is set the reference myObject to null, it does not affect the object myObject once pointed to except to simply decrement the reference count by 1. Since myOtherObject still refers to that object, it is not yet available to be collected.

Using

<a href="foo.html"><div class="xyz"></div></a>

works in browsers, even though it violates current HTML specifications. It is permitted according to HTML5 drafts.

When you say that it does not work, you should explain exactly what you did (including jsfiddle code is a good idea), what you expected, and how the behavior different from your expectations.

It is unclear what you mean by “all the content in that div is in the css”, but I suppose it means that the content is really empty in HTML markup and you have CSS like

.xyz:before { content: "Hello world"; }

The entire block is then clickable, with the content text looking like link text there. Isn’t this what you expected?

A C compiler itself won't provide you with GUI functionality, but there are plenty of libraries for that sort of thing. The most popular is probably GTK+, but it may be a little too complicated if you are just starting out and want to quickly get a GUI up and running.

For something a little simpler, I would recommend IUP. With it, you can use a simple GUI definition language called LED to layout controls (but you can do it with pure C, if you want to).

package name with 0 may cause problem for sharedPreference.

(OK) con = createPackageContext("com.example.android.sf1", 0);

(Problem but no error)

con = createPackageContext("com.example.android.sf01", 0);

Since an abstract class can have variables of all access modifiers, they have to be initialized to default values, so constructor is necessary. As you instantiate the child class, a constructor of an abstract class is invoked and variables are initialized.

On the contrary, an interface does contain only constant variables means they are already initialized. So interface doesn't need a constructor.

• Go to: C:\Users\ [youruserdirectory] \bash_profile

• In your bash_profile file type - alias desk='cd " [DIRECTORY LOCATION] "'

• Refresh your User directory where the bash_profile file exists then reopen your CMD or Git Bash window

Type in desk to see if you get to the Desktop location or the location you want in the "DIRECTORY LOCATION" area above

Note: [ desk ] can be what ever name that you choose and should get you to the location you want to get to when typed in the CMD window.

I've always used this with great success:

$array = preg_split("/\r\n|\n|\r/", $string);

(updated with the final \r, thanks @LobsterMan)

Please note this doesn't solve the cookie sharing process, as in general this is bad practice.

You need to be using JSONP as your type:

From $.ajax documentation: Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation.

$.ajax(
    { 
      type: "POST",
      url: "http://example.com/api/getlist.json",
      dataType: 'jsonp',
      xhrFields: {
           withCredentials: true
      },
      crossDomain: true,
      beforeSend: function(xhr) {
            xhr.setRequestHeader("Cookie", "session=xxxyyyzzz");
      },
      success: function(){
           alert('success');
      },
      error: function (xhr) {
             alert(xhr.responseText);
      }
    }
);

REVERSIBLE Method to Discard All Changes:

I found this question after after making a merge and forgetting to checkout develop immediately afterwards. You guessed it: I started modifying a few files directly on master. D'Oh! As my situation is hardly unique (we've all done it, haven't we ;->), I'll offer a reversible way I used to discard all changes to get master looking like develop again.

After doing a git diff to see what files were modified and assess the scope of my error, I executed:

git stash
git stash clear

After first stashing all the changes, they were next cleared. All the changes made to the files in error to master were gone and parity restored.

Let's say I now wanted to restore those changes. I can do this. First step is to find the hash of the stash I just cleared/dropped:

git fsck --no-reflog | awk '/dangling commit/ {print $3}'

After learning the hash, I successfully restored the uncommitted changes with:

git stash apply hash-of-cleared-stash

I didn't really want to restore those changes, just wanted to validate I could get them back, so I cleared them again.

Another option is to apply the stash to a different branch, rather than wipe the changes. So in terms of clearing changes made from working on the wrong branch, stash gives you a lot of flexibility to recover from your boo-boo.

Anyhoo, if you want a reversible means of clearing changes to a branch, the foregoing is a less dangerous way in this use-case.

Logical OR is ||, logical AND is &&. If you need the negation NOT, prefix your expression with !.

Example:

X = (A && B) || C || !D;

Then X will be true when either A and B are true or if C is true or if D is not true (i.e. false).

If you wanted bit-wise AND/OR/NOT, you would use &, | and ~. But if you are dealing with boolean/truth values, you do not want to use those. They do not provide short-circuit evaluation for example due to the way a bitwise operation works.

I used to have exactly the same problem, and finally it was solved.

I put all the dependent DLLs into the same folder where mylib.dll was stored and make sure the JAVA Compiler could find it (if there is no mylib.dll in the compilation path, there would be an error reporting this during compiling). The important thing you need to notice is you must make sure all the dependent libs are of the same version with mylib.dll, for example if your mylib.dll is release version then you should also put the release version of all its dependent libs there.

Hope this could help others who have encountered the same problem.

Update: Using XAMP

After I’ve written this blog post I’ve figured out that XAMP, although very similar to WAMP, doesn’t force you to run Apache as a service, instead it can run it as a regular process. So I ended up using XAMP, and changed Apache port to 8080 so now everything works.

WAMP Issues

If you have Window 7 or later you may have come across issues with WAMP server trying to start Apache service on port 80 and failing.

There are many conflict and issues that might have come up. Before you try anything, check if you have ZoneAlarm, Nod32, or any other program/firewall that might be blocking Apache server. If you’re sure that firewall isn’t the problem here is a couple of fixes that you can try.

NOTE: After every fix you try, you must click on yellow WAMP icon and choose Restart All Services

Checking which process is causing the problem

Open Command Prompt window by typing cmd in Run command box or Start Search, and hit Enter. Type in the following command: netstat -o -n -a | findstr 0.0:80 The last column of each row is the process identified (process ID or PID). Identify which process or application is using the port by matching the PID against PID number in Task Manager. If you don’t see PID column in your Task Manager you need to go to Processes tab -> View Menu -> Select Columns and choose PID from the list Now, you may have identified application that reserves port 80, or you may have found out that System is using your port 80. That means that one of internal services is using your port, in which case continue reading further. Conflict with Skype

If you found out that Skype is using your port 80, you need to change some settings in Skype. On Windows, Skype reserves port 80 which is used for HTTP. Apache requires this port. So if you’re running Skype, you must go to Tools > Options. Then in the Advanced section, select Connection. Un-check the box that says “Use port 80 and 443 as alternatives for incoming connection“. Quit Skype and restart. The issue should be resolved.

Conflict with IIS Server

IIS Server and Apache are both web server that use port 80 so they might be in conflict. Try stopping IIS by:

Going into Control Panel -> Administrative Tools -> Internet Information Services Right click on Default Web Site Click on Stop option in the popup menu, and see of the listener on port 80 has cleared. Conflict with MS SQL Server

MS SQL Server installs “SQL Server Reporting Services (MSSQLSERVER)” that apparently defaults to 80. You can try stopping it to free up port 80.

Go to Control Panel -> Administrative Tools -> Services There find MSSQLSERVER (might be found also under SQL Server) Double click it -> Click Stop Under Startup type: choose Manual Other Services that can cause conflicts

As described above for MS SQL Server:

Go to Control Panel -> Administrative Tools -> Services You can try stopping: Web Deployment Agent Service Windows Remote Management Autodesk EDM Server World Wide Web Publishing Service There are probably more of them, but this where the ones that I tryed.

Try turning off HTTP driver directly

If you’ve tried everything mentioned above and your WAMP server is still not working you could try this (which eventually helped me).

Right click on My Computer icon -> Properties Go to Device Manager Click on View menu and chooseShow hidden devices Now from the list choose Non-Plug and Play devices Double click HTTP -> go to Driver For Type choose Disabled Restart your computer After your computer boots up you should be able to start up WAMP server.

If everything else fails

You could try changing Apache server to listen to some other port other than port 80.

Click on yellow WAMP icon in your taskbar Choose Apache -> httpd.conf Inside find these two lines of code:

Listen 80 ServerName localhost:80 and change them to something like this (they are not one next to the other):

Listen 8080 ServerName localhost:8080 Restart all services, and try typing localhost:8080 into your browser. WAMP server should now be working.

CTRL + 1 can also be used which will suggest to import.

If you are working with elements of unknown size, and you want to use position: absolute on them or their siblings, you're inevitably going to have to deal with overlap. By setting absolute position you're removing the element from the document flow, but the behaviour you want is that your element should be be pushed around by its siblings so as not to overlap...ie it should flow! You're seeking two totally contradictory things.

You should rethink your layout.

Perhaps what you want is that the .btn element should be absolutely positioned with respect to one of its preceding siblings, rather than against their common parent? In that case, you should set position: relative on the element you'd like to position the button against, and then make the button a child of that element. Now you can use absolute positioning and control overlap.

You can use this.props.children to render whatever children the component contains:

const Wrap = ({ children }) => <div>{children}</div>

export default () => <Wrap><h1>Hello word</h1></Wrap>

Change this line:

mMyListView.setAdapter(new ArrayAdapter<String>(this, 
                           android.R.layout.simple_list_item_1, 
                           listItems));

to:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                   android.R.layout.simple_list_item_1, 
                                   listItems)
mMyListView.setAdapter(adapter);

and after updating the value of a list item, call:

adapter.notifyDataSetChanged();

FYI, this is probably faster,

SELECT count(1) FROM (SELECT distinct productId WHERE keyword = '$keyword') temp

than this,

SELECT COUNT(DISTINCT productId) WHERE keyword='$keyword'

I can think of three options:

Implement RFC 2217

RFC 2217 covers a com port to TCP/IP standard that allows a client on one system to emulate a serial port to the local programs, while transparently sending and receiving data and control signals to a server on another system which actually has the serial port. Here's a high-level overview.

What you would do is find or implement a client com port driver that would implement the client side of the system on your PC - appearing to be a real serial port but in reality shuttling everything to a server. You might be able to get this driver for free from Digi, Lantronix, etc in support of their real standalone serial port servers.

You would then implement the server side of the connection locally in another program - allowing the client to connect and issuing the data and control commands as needed.

It's probably non trivial, but the RFC is out there, and you might be able to find an open source project that implements one or both sides of the connection.

Modify the linux serial port driver

Alternately, the serial port driver source for Linux is readily available. Take that, gut the hardware control pieces, and have that one driver run two /dev/ttySx ports, as a simple loopback. Then connect your real program to the ttyS2 and your simulator to the other ttySx.

Use two USB<-->Serial cables in a loopback

But the easiest thing to do right now? Spend $40 on two serial port USB devices, wire them together (null modem) and actually have two real serial ports - one for the program you're testing, one for your simulator.

Assume your code is looking for the file say app.properties. Copy this file to any dir and add this dir to classpath, by creating a setenv.sh in the bin dir of tomcat.

In your setenv.sh of tomcat( if this file is not existing, create one , tomcat will load this setenv.sh file. #!/bin/sh CLASSPATH="$CLASSPATH:/home/user/config_my_prod/"

You should not have your properties files in ./webapps//WEB-INF/classes/app.properties

Tomcat class loader will override the with the one from WEB-INF/classes/

I had this problem running unit tests (xunit) in Visual Studio 2015 and came across the following fix:

Menu Bar -> Test -> Test Settings -> Default Processor Architecture -> X64

The feedback you get on the interactive interpreter uses repr too. When you type in an expression (let it be expr), the interpreter basically does result = expr; if result is not None: print repr(result). So the second line in your example is formatting the string foo into the representation you want ('foo'). And then the interpreter creates the representation of that, leaving you with double quotes.

Why when I combine %r with double-quote and single quote escapes and print them out, it prints it the way I'd write it in my .py file but not the way I'd like to see it?

I'm not sure what you're asking here. The text single ' and double " quotes, when run through repr, includes escapes for one kind of quote. Of course it does, otherwise it wouldn't be a valid string literal by Python rules. That's precisely what you asked for by calling repr.

Also note that the eval(repr(x)) == x analogy isn't meant literal. It's an approximation and holds true for most (all?) built-in types, but the main thing is that you get a fairly good idea of the type and logical "value" from looking the the repr output.

i wrote this sp to create automatically the schema with all things, pk, fk, partitions, constraints... I wrote it to run in same sp.

When you specify a percentage for max-height on a child, it is a percentage of the parent's actual height, not the parent's max-height, oddly enough. The same applies to max-width.

So, when you don't specify an explicit height on the parent, then there's no base height for the child's max-height to be calculated from, so max-height computes to none, allowing the child to be as tall as possible. The only other constraint acting on the child now is the max-width of its parent, and since the image itself is taller than it is wide, it overflows the container's height downwards, in order to maintain its aspect ratio while still being as large as possible overall.

When you do specify an explicit height for the parent, then the child knows it has to be at most 100% of that explicit height. That allows it to be constrained to the parent's height (while still maintaining its aspect ratio).

import requests

url = requests.get("http://yahoo.com")
htmltext = url.text
print(htmltext)

This will work similar to urllib.urlopen.

I got it worked with this command curl -F 'filename=@/home/yourhomedirextory/file.txt' http://yourserver/upload

It probably aimed to select all the informations in your table. If you use this kind of query (for example in PHP) :

mysql_query("SELECT * FROM newsletter WHERE email = '$email'");

The email ' OR 1=1/* will give this kind of query :

mysql_query("SELECT * FROM newsletter WHERE email = '' OR 1=1/*");

So it selects all the rows (because 1=1 is always true and the rest of the query is 'commented'). But it was not successful

• if strings used in your queries are escaped
• if you don't display all the queries results on a page...

To phyzome's answer (most highly voted one), it seems to me that if you put "identified by" at the end of the grant statement, the user will be created automatically. But if you don't, the user is not created. The following code works for me,

GRANT USAGE ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password';
DROP USER 'username'@'localhost';

Hope this helps.

The 2017 answer is: Use the date and time classes introduced in Java 8 (and also backported to Java 6 and 7 in the ThreeTen Backport).

If you want to interpret the date-time string in the computer’s time zone:

    long millisSinceEpoch = LocalDateTime.parse(myDate, DateTimeFormatter.ofPattern("uuuu/MM/dd HH:mm:ss"))
            .atZone(ZoneId.systemDefault())
            .toInstant()
            .toEpochMilli();

If another time zone, fill that zone in instead of ZoneId.systemDefault(). If UTC, use

    long millisSinceEpoch = LocalDateTime.parse(myDate, DateTimeFormatter.ofPattern("uuuu/MM/dd HH:mm:ss"))
            .atOffset(ZoneOffset.UTC)
            .toInstant()
            .toEpochMilli();

Thanks to @Dirk Lachowski for pointing me in the right direction. The solution isn't as elegant as I would have liked, but I got it working. Reading the spring docs, I can listen on the EmbeddedServletContainerInitializedEvent and get the port once the server is up and running. Here's what it looks like -

import org.springframework.boot.context.embedded.EmbeddedServletContainerInitializedEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;




    @Component
    public class MyListener implements ApplicationListener<EmbeddedServletContainerInitializedEvent> {

      @Override
      public void onApplicationEvent(final EmbeddedServletContainerInitializedEvent event) {
          int thePort = event.getEmbeddedServletContainer().getPort();
      }
    }

This code is working fine for me.

jQuery("a").filter(function () {
        return this.innerHTML.indexOf("Delete") == 0;
        }).click(function () { return confirm("Are you sure you want to delete this record?"); 
});

The best way to do it, is to define a function, and pass it a parameter of the ID's name that you want to grab from the DOM, then every time you want to grab an ID and store it inside an array, then you can call the function

<p id="testing">Demo test!</p>

function grabbingId(element){
    var storeId = document.getElementById(element);

    return storeId;
}


grabbingId("testing").syle.color = "red";

Just adding a little more info.

JPA manages the version under the hood for you, however it doesn't do so when you update your record via JPAUpdateClause, in such cases you need to manually add the version increment to the query.

Same can be said about updating via JPQL, i.e. not a simple change to the entity, but an update command to the database even if that is done by hibernate

Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error() and curl_errno() will contain further information in case of failure:

try {
    $ch = curl_init();

    // Check if initialization had gone wrong*    
    if ($ch === false) {
        throw new Exception('failed to initialize');
    }

    curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt(/* ... */);

    $content = curl_exec($ch);

    // Check the return value of curl_exec(), too
    if ($content === false) {
        throw new Exception(curl_error($ch), curl_errno($ch));
    }

    /* Process $content here */

    // Close curl handle
    curl_close($ch);
} catch(Exception $e) {

    trigger_error(sprintf(
        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);

}

^* The curl_init() manual states:

Returns a cURL handle on success, FALSE on errors.

I've observed the function to return FALSE when you're using its $url parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.

The reason is that for deleting an object, Hibernate requires that the object is in persistent state. Thus, Hibernate first fetches the object (SELECT) and then removes it (DELETE).

Why Hibernate needs to fetch the object first? The reason is that Hibernate interceptors might be enabled (http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/events.html), and the object must be passed through these interceptors to complete its lifecycle. If rows are delete directly in the database, the interceptor won't run.

On the other hand, it's possible to delete entities in one single SQL DELETE statement using bulk operations:

Query q = session.createQuery("delete Entity where id = X");
q.executeUpdate();

It does appear red on Firefox and IE 8. But perhaps you need to change the border-style too.

.field_set{_x000D_
  border-color: #F00;_x000D_
  border-style: solid;_x000D_
}

<fieldset class="field_set">_x000D_
  <legend>box</legend>_x000D_
  <table width="100%" border="0" cellspacing="0" cellpadding="0">_x000D_
    <tr>_x000D_
      <td>&nbsp;</td>_x000D_
    </tr>_x000D_
  </table>_x000D_
</fieldset>

I used to do this a lot when I worked with Classic ASP. Usually I used it when server-side validation was needed of some sort for the input (before the days of AJAX). The main draw back I see is that it doesn't separate programming logic from the presentation, at the file level.

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

You have a couple of things fighting in your strings.

• lack of correct MySQL quoting (mysql_real_escape_string())
• potential automatic 'magic quote' -- check your gpc_magic_quotes setting
• embedded string variables, which means you have to know how PHP correctly finds variables

It's also possible that the single-quoted value is not present in the parameters to the first query. Your example is a proper name, after all, and only the second query seems to be dealing with names.

If you are using latest versions of Angular (2/5/6) :

In your component.ts

//x.component.ts
prefs = false;

hidePrefs(){
   this.prefs = true;
}

In java, every numeric expression like:

anyPrimitive zas = 1;
anyPrimitive bar = 3;
?? x = zas  + bar 

x will always result to be at least an int, or a long if one of the addition elements was a long.

But there's are some quirks tough

byte a = 1; // 1 is an int, but it won't compile if you use a variable
a += 2; // the shortcut works even when 2 is an int
a++; // the post and pre increment operator work

Previous anwser works fine. I would just add that you dont need to specify CURLOPT_POSTFIELDS as "xmlRequest=" . $input_xml to read your $_POST. You can use file_get_contents('php://input') to get the raw post data as plain XML.

\if what you have posted is exactly what you are using then your problem is a bit obvious. Now assuming in your web.config you have you connection string defined like this

 <add name="SiteSqlServer" connectionString="Data Source=(local);Initial Catalog=some_db;User ID=sa;Password=uvx8Pytec" providerName="System.Data.SqlClient" />

In your code you should use the value in the name attribute to refer to the connection string you want (you could actually define several connection strings to different databases), so you would have

 con.ConnectionString = ConfigurationManager.ConnectionStrings["SiteSqlServer"].ConnectionString;

You should be able to do this via the command line arguments, assuming these are Sun VMs installed using the usual Windows InstallShield mechanisms with the JVM finder EXE in system32.

Type java -help for the options. In particular, see:

-version:<value>
              require the specified version to run
-jre-restrict-search | -jre-no-restrict-search
              include/exclude user private JREs in the version search

Replace all commas with underscore in the column names

data.columns= data.columns.str.replace(' ','_',regex=True)

Try following these if these might help:

Since your installation works on the terminal you installed, all the exports you did, work on the current bash and its child process. but is not spawned to new terminals.

env variables are lost if the session is closed; using .bash_profile, you can make it available in all sessions, since when a bash session starts, it 'runs' its .bashrc and .bash_profile

Now follow these steps and see if it helps:

1. type env | grep M2_HOME on the terminal that is working. This should give something like

   M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1

2. typing env | grep JAVA_HOME should give like this:

   JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home

Now you have the PATH for M2_HOME and JAVA_HOME.

If you just do ls /usr/local/apache-maven/apache-maven-3.1.1/bin, you will see mvn binary there. All you have to do now is to point to this location everytime using PATH. since bash searches in all the directory path mentioned in PATH, it will find mvn.

1. now open .bash_profile, if you dont have one just create one

   vi ~/.bash_profile

Add the following:

#set JAVA_HOME
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home
export JAVA_HOME


M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1
export M2_HOME

PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
export PATH

1. save the file and type source ~/.bash_profile. This steps executes the commands in the .bash_profile file and you are good to go now.

2. open a new terminal and type mvn that should work.

$('input:radio[name=theme]').bind(
  'click',
  function(){
    $(this).val();
});

@Html.DropdownListFor(model=model->Gender,new List<SelectListItem>
{
 new ListItem{Text="Male",Value="Male"},
 new ListItem{Text="Female",Value="Female"},
 new ListItem{Text="--- Select -----",Value="-----Select ----"}
}
)

Go to management studio and do everything you describe, only instead of clicking OK, click on Script. It will show the code it will run which you can then incorporate in your scripts.

In this case, you want:

ALTER DATABASE [MyDatabase] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO

For use of the TextWatcher...

et1.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

        // TODO Auto-generated method stub
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        // TODO Auto-generated method stub
    }

    @Override
    public void afterTextChanged(Editable s) {

        // TODO Auto-generated method stub
    }
});

Use moment.js to parse dates:

var caseOne = moment("Jul 8, 2005", "MMM D, YYYY", true).toDate();
var caseTwo = moment("2005-07-08", "YYYY-MM-DD", true).toDate();

The 3rd argument determines strict parsing (available as of 2.3.0). Without it moment.js may also give incorrect results.

Also had this issue, This array was out of range:

order: [1, 'asc'],

(KOTLIN) So, as of April 7th, 2020 none of the above mentioned options worked, but here's what worked for me:

1. If you want to store the bitmap in a val and set an imageView with it, use this:

   val bitmap = BitmapFactory.decodeFile(currentPhotoPath).also { bitmap -> imageView.setImageBitmap(bitmap) }

2. If you just want to set the bitmap to and imageView, use this:

   BitmapFactory.decodeFile(currentPhotoPath).also { bitmap -> imageView.setImageBitmap(bitmap) }

For those looking at this in 2020, you may notice that accepted answer is deprecated in 2020, but there is a similar approach available using terms_set and minimum_should_match_script combination.

Please see the detailed answer here in the SO thread

how about something like this...

var directory = new DirectoryInfo("C:\\MyDirectory");
var myFile = (from f in directory.GetFiles()
             orderby f.LastWriteTime descending
             select f).First();

// or...
var myFile = directory.GetFiles()
             .OrderByDescending(f => f.LastWriteTime)
             .First();

As has been mentioned by others, std::unique_lock tracks the locked status of the mutex, so you can defer locking until after construction of the lock, and unlock before destruction of the lock. std::lock_guard does not permit this.

There seems no reason why the std::condition_variable wait functions should not take a lock_guard as well as a unique_lock, because whenever a wait ends (for whatever reason) the mutex is automatically reacquired so that would not cause any semantic violation. However according to the standard, to use a std::lock_guard with a condition variable you have to use a std::condition_variable_any instead of std::condition_variable.

Edit: deleted "Using the pthreads interface std::condition_variable and std::condition_variable_any should be identical". On looking at gcc's implementation:

• std::condition_variable::wait(std::unique_lock&) just calls pthread_cond_wait() on the underlying pthread condition variable with respect to the mutex held by unique_lock (and so could equally do the same for lock_guard, but doesn't because the standard doesn't provide for that)
• std::condition_variable_any can work with any lockable object, including one which is not a mutex lock at all (it could therefore even work with an inter-process semaphore)

Just found the thing needed. Now, I can store products visited on cookies and show them later when they get back to the site.

// set the cookies
setcookie("product[cookiethree]", "cookiethree");
setcookie("product[cookietwo]", "cookietwo");
setcookie("product[cookieone]", "cookieone");

// after the page reloads, print them out
if (isset($_COOKIE['product'])) {
    foreach ($_COOKIE['product'] as $name => $value) {
        $name = htmlspecialchars($name);
        $value = htmlspecialchars($value);
        echo "$name : $value <br />\n";
    }
}

If the imagestr was bitmap data (which we now know it isn't) you could use this

imagestr is the base64 encoded string
width is the width of the image
height is the height of the image

from PIL import Image
from base64 import decodestring

image = Image.fromstring('RGB',(width,height),decodestring(imagestr))
image.save("foo.png")

Since the imagestr is just the encoded png data

from base64 import decodestring

with open("foo.png","wb") as f:
    f.write(decodestring(imagestr))

Alias to move one tag to a different commit.

In your sample, to move commit with hash e2ea1639 do: git tagm v0.1 e2ea1639.

For pushed tags, use git tagmp v0.1 e2ea1639.

Both alias keeps you original date and message. If you use git tag -d you lost your original message.

Save them on your .gitconfig file

# Return date of tag. (To use in another alias)
tag-date = "!git show $1 | awk '{ if ($1 == \"Date:\") { print substr($0, index($0,$3)) }}' | tail -2 | head -1 #"

# Show tag message
tag-message = "!git show $1 | awk -v capture=0 '{ if(capture) message=message\"\\n\"$0}; BEGIN {message=\"\"}; { if ($1 == \"Date:\" && length(message)==0 ) {capture=1}; if ($1 == \"commit\" ) {capture=0}  }; END { print message }' | sed '$ d' | cat -s #"

### Move tag. Use: git tagm <tagname> <newcommit> 
tagm = "!GIT_TAG_MESSAGE=$(git tag-message $1) && GIT_COMMITTER_DATE=$(git tag-date $1) && git tag-message $1 && git tag -d $1 && git tag -a $1 $2 -m \"$GIT_TAG_MESSAGE\" #"

### Move pushed tag. Use: git tagmp <tagname> <newcommit> 
tagmp = "!git tagm $1 $2 && git push --delete origin $1 && git push origin $1 #"

If you want to append a value to myList, use myList.append(s).

Strings are immutable -- you can't append to them.

I recently spent a week studying lot of solutions to validate my forms in an app. I started with all the most stared one but I couldn't find one who was working as I was expected. After few days, I became quite frustrated until i found a very new and amazing plugin: https://github.com/kettanaito/react-advanced-form

The developper is very responsive and his solution, after my research, merit to become the most stared one from my perspective. I hope it could help and you'll appreciate.

1. You can use an interface to provide a click listener. I use this technique with ListViews, too.
2. No divider: Simply add in your row a View with a width of match_parent and a height of 1dp and give it a background color.
3. Simply use a StateList selector for the row background.
4. addHeaderView can be avoided in ListViews, too: simply put the Header outside the View.

So, if efficiency is your concern, then yes, it's a good idea to replace a ListView with a RecyclerView.

What you want is this constructor: std::string ( const string& str, size_t pos, size_t n = npos ), passing pos as 0. Your const char* c-style string will get implicitly cast to const string for the first parameter.

const char *c_style = "012abd";
std::string cpp_style = new std::string(c_style, 0, 10);

After some tinkering for a while with different solutions i found out that one must create a notification channel in Android 8.1 and above.

private fun startForeground() {
    val channelId =
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                createNotificationChannel("my_service", "My Background Service")
            } else {
                // If earlier version channel ID is not used
                // https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#NotificationCompat.Builder(android.content.Context)
                ""
            }

    val notificationBuilder = NotificationCompat.Builder(this, channelId )
    val notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setPriority(PRIORITY_MIN)
            .setCategory(Notification.CATEGORY_SERVICE)
            .build()
    startForeground(101, notification)
}

@RequiresApi(Build.VERSION_CODES.O)
private fun createNotificationChannel(channelId: String, channelName: String): String{
    val chan = NotificationChannel(channelId,
            channelName, NotificationManager.IMPORTANCE_NONE)
    chan.lightColor = Color.BLUE
    chan.lockscreenVisibility = Notification.VISIBILITY_PRIVATE
    val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    service.createNotificationChannel(chan)
    return channelId
}

From my understanding background services are now displayed as normal notifications that the user then can select to not show by deselecting the notification channel.

Update: Also don't forget to add the foreground permission as required Android P:

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

I would like share an example to understand the usage of stream().filter

Code Snippet: Sample program to identify even number.

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

public void fetchEvenNumber(){
        List<Integer> numberList = new ArrayList<>();
        numberList.add(10);
        numberList.add(11);
        numberList.add(12);
        numberList.add(13);
        numberList.add(14);
        numberList.add(15);

        List<Integer> evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());
        System.out.println(evenNumberListObj);
}

Output will be : [10, 12, 14]

List evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());

numberList: it is an ArrayList object contains list of numbers.

java.util.Collection.stream() : stream() will get the stream of collection, which will return the Stream of Integer.

filter: Returns a stream that match the given predicate. i.e based on given condition (i -> i%2 != 0) returns the matching stream.

collect: whatever the stream of Integer filter based in the filter condition, those integer will be put in a list.

Finaly I found another answer for this problem. and this is working for me. Just add below datas to the your webconfig file.

<configuration>
 <system.webServer>
  <security>
   <requestFiltering>
    <verbs allowUnlisted="true">
     <add verb="OPTIONS" allowed="false" />
    </verbs>
   </requestFiltering>
  </security>
 </system.webServer>
</configuration>

Form more information, you can visit this web site: http://www.iis.net/learn/manage/configuring-security/use-request-filtering

if you want to test your web site, is it working or not... You can use "HttpRequester" mozilla firefox plugin. for this plugin: https://addons.mozilla.org/En-us/firefox/addon/httprequester/

This has been answered by a lot of people, but I feel like the simplest solution has been left out.

SQL SERVER (I believe its 2012+) has implicit string equivalents for DATETIME2 as shown here

Look at the section on "Supported string literal formats for datetime2"

To answer the OPs question explicitly:

DECLARE @myVar NCHAR(32)
DECLARE @myDt DATETIME2
SELECT @myVar = @GETDATE()
SELECT @myDt = @myVar
PRINT(@myVar)
PRINT(@myDt)

output:

Jan 23 2019 12:24PM             
2019-01-23 12:24:00.0000000

Note: The first variable (myVar) is actually holding the value '2019-01-23 12:24:00.0000000' as well. It just gets formatted to Jan 23 2019 12:24PM due to default formatting set for SQL SERVER that gets called on when you use PRINT. Don't get tripped up here by that, the actual string in (myVer) = '2019-01-23 12:24:00.0000000'

Two things are important for above solutions to work:

1. When applying bindings, you need to specify scope (element) !!

2. When clearing bindings, you must specify exactly same element used for scope.

Code is below

Markup

<div id="elt1" data-bind="with: data">
    <input type="text" data-bind="value: text1" >
</form>

Binding view

var myViewModel = {
  "data" : {
    "text1" : "bla bla"
  }
}:

Javascript

ko.applyBindings(myViewModel, document.getElementById('elt1'));

Clear bindings

ko.cleanNode(document.getElementById('elt1'));

Using a fadeTo() that is fading to an opacity of 500 in 2 seconds in "I Can Has Kittenz"'s code isn't readable to me. I think it's better using other options like a delay()

$(".alert").delay(4000).slideUp(200, function() {
    $(this).alert('close');
});

Robert Rossney has a good solution. Here's an alternative solution I've used in the past that separates out the "Overlay" from the rest of the content. This solution takes advantage of the attached property Panel.ZIndex to place the "Overlay" on top of everything else. You can either set the Visibility of the "Overlay" in code or use a DataTrigger.

<Grid x:Name="LayoutRoot">

 <Grid x:Name="Overlay" Panel.ZIndex="1000" Visibility="Collapsed">
    <Grid.Background>
      <SolidColorBrush Color="Black" Opacity=".5"/>
    </Grid.Background>

    <!-- Add controls as needed -->
  </Grid>

  <!-- Use whatever layout you need -->
  <ContentControl x:Name="MainContent" />

</Grid>

Try SELECT CAST(field1 AS DECIMAL(10,2)) field1 and replace 10,2 with whatever precision you need.

If you have an Array of strings, you can also initialize it like this:

array = %w{1 2 3}

just separate each element with any whitespace

Use @ViewChildren from @angular/core to get a reference to the components

template

<div *ngFor="let v of views">
    <customcomponent #cmp></customcomponent>
</div>

component

import { ViewChildren, QueryList } from '@angular/core';

/** Get handle on cmp tags in the template */
@ViewChildren('cmp') components:QueryList<CustomComponent>;

ngAfterViewInit(){
    // print array of CustomComponent objects
    console.log(this.components.toArray());
}

l?i?v?e? ?d?e?m?o?

If your data is complex, high in quantity or you need to query it locally then object databases might be a valid option. I'd suggest looking at Db4o or Karvonite.

This worked for me:

//Button method example
 @IBAction func LogOutPressed(_ sender: UIBarButtonItem) {

        do {
            try Auth.auth().signOut()
            navigationController?.popToRootViewController(animated: true)

        } catch let signOutError as NSError {
          print ("Error signing out: %@", signOutError)
        }


    }

While it's possible to do a proper modulo by checking whether the value is negative and correct it if it is (the way many have suggested), there is a more compact solution.

(a % b + b) % b

This will first do the modulo, limiting the value to the -b -> +b range and then add b in order to ensure that the value is positive, letting the next modulo limit it to the 0 -> b range.

Note: If b is negative, the result will also be negative

Using Perl:

perl -p -i -e 's/ /\t/g' file.txt

An interface is so called because it provides an interface of methods to a caller (or a COM client for instance) that are implemented by some class. By polymorphically casting an object pointer to the type of an interface that the object's class implements, it restricts the access of the object to functions and members of the interface that it implements, separated from other COM interfaces the coclass might implement. The client does not need to know what class implements the interface or what other methods are present in the class; the object presents as an instance of the interface it knows (where the instance of the class has been polymorphically cast to the interface subinstance) and it just uses the interface by calling the methods of the interface on the interface instance. All details of the actual implementation and extraneous functionality / details implemented by different interfaces are separated from the interface the caller expects -- the caller just uses the interface it has with the object, and the underlying object implementation is called without the caller having to know the location or the details of the implementation. Accessing the object through the interface (a pointer of the type of the interface) is a form of encapsulation that syntactically prevents unauthorised access to the object as well as hiding implementation details and other functionality that does not pertain to the interface and its defined personality.

An interface is where all methods are virtual and abstract (abstract is known as pure virtual in C++; all abstract methods contain the virtual specifier and therefore are virtual). An abstract class is where at least one of the methods is virtual and specified as abstract (or pure virtual in C++). Other details differ across languages. All interface attributes are implicitly public static final in java but they aren't in C++. Java allows non-static attributes in abstract classes but C++ allows them in both. Attributes cannot be virtual / abstract in either language.

I know its a bit late but just found a library Microsoft.VisualBasic.FileIO which has TextFieldParser class to process csv files.

Seaborn's barplot returns an axis-object (not a figure). This means you can do the following:

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
ax = sns.barplot(x = 'val', y = 'cat', 
              data = fake, 
              color = 'black')
ax.set(xlabel='common xlabel', ylabel='common ylabel')
plt.show()

You can take a look at this sample I made. It uses the os.path.walk function which is deprecated beware.Uses a list to store all the filepaths

root = "Your root directory"
ex = ".txt"
where_to = "Wherever you wanna write your file to"
def fileWalker(ext,dirname,names):
    '''
    checks files in names'''
    pat = "*" + ext[0]
    for f in names:
        if fnmatch.fnmatch(f,pat):
            ext[1].append(os.path.join(dirname,f))


def writeTo(fList):

    with open(where_to,"w") as f:
        for di_r in fList:
            f.write(di_r + "\n")






if __name__ == '__main__':
    li = []
    os.path.walk(root,fileWalker,[ex,li])

    writeTo(li)

It is recommended to check default terminal shell before set JAVA_HOME environment variable, via following commands:

$ echo $SHELL
/bin/bash

If your default terminal is /bin/bash (Bash), then you should use @hygull method

If your default terminal is /bin/zsh (Z Shell), then you should set these environment variable in ~/.zshenv file with following contents:

export JAVA_HOME="$(/usr/libexec/java_home)"

Similarly, any other terminal type not mentioned above, you should set environment variable in its respective terminal env file.

This method tested working in macOS Mojave Version 10.14.6.

You can use text-align: center on the parent and change the img to display: inline-block → it therefore behaves like a text-element and is will be centered if the parent has a width!

img {
    display: inline-block
}

Come on guys :) We could do it simpler, by examples:

/this-is-an-endpoint
/another/endpoint
/some/other/endpoint
/login
/accounts
/cart/items

and when put under a domain, it would look like:

https://example.com/this-is-an-endpoint
https://example.com/another/endpoint
https://example.com/some/other/endpoint
https://example.com/login
https://example.com/accounts
https://example.com/cart/items

Can be either http or https, we use https in the example.

Also endpoint can be different for different HTTP methods, for example:

GET /item/{id}
PUT /item/{id}

would be two different endpoints - one for retrieving (as in "cRud" abbreviation), and the other for updating (as in "crUd")

And that's all, really that simple!

Another reason you can get this error is that Eclipse can't find the correct file.

Check out where Eclipse is looking for your SDK files. You can do this on the command line. Below is an example for the windows command prompt for an avd I created and named 'SonyTabletS':

c:\Program Files (x86)\Android\android-sdk\tools> emulator @SonyTabletS -verbose

The first line returned shows where eclipse is looking for the SDK files and will look something like:

emulator: found ANDROID_SDK_ROOT: C:\Program Files (x86)\Android\android-sdk

Make sure that location is correct.

In my case, ANDROID_SDK_ROOT was initially set incorrectly to my home directory. This is because I set it that way by blindly following the Sony Tablet S SDK install instructions and adding an ANDROID_SDK_ROOT environment variable with the incorrect path.

Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.

stuff is an object and push is a method of an array. So you cannot use stuff.push(..).

Lets say you define stuff as an array stuff = []; then you can call push method on it.

This works because the object[key/value] is well formed.

stuff.push( {'name':$(this).attr('checked')} );

Whereas this will not work because the object is not well formed.

stuff.push( {$(this).attr('value'):$(this).attr('checked')} );

This works because we are treating stuff as an associative array and added values to it

stuff[$(this).attr('value')] = $(this).attr('checked');

From what I understand of your request, this should work:

<script>
//  var status  = document.getElementsByID("uniqueID"); // this works too
var status  = document.getElementsByName("status")[0];
var jsonArr = [];

for (var i = 0; i < status.options.length; i++) {
    jsonArr.push({
        id: status.options[i].text,
        optionValue: status.options[i].value
    });
}
</script>

big=small=values[0]; //assigns element to be highest or lowest value

Should be AFTER fill loop

//counts to 20 and prompts user for value and stores it
for ( int i = 0; i < 20; i++ )
{
    cout << "Enter value " << i << ": ";
    cin >> values[i];
}
big=small=values[0]; //assigns element to be highest or lowest value

since when you declare array - it's unintialized (store some undefined values) and so, your big and small after assigning would store undefined values too.

And of course, you can use std::min_element, std::max_element, or std::minmax_element from C++11, instead of writing your loops.

1. Extract the package to C:\ from here and install it

2. Copy the path C:\MinGW\bin which contains gcc.exe.

3. go to Control Panel->System->Advanced>Environment variables, and add or modify PATH. (just concatenate with ';')

4. Then, open a cmd.exe command prompt (Windows + R and type cmd, if already opened, please close and open a new one, to get the path change)

5. change the folder to your file path by cd D:\c code Path

6. type gcc main.c -o helloworld.o. It will compile the code. for C++ use g++

7 type ./helloworld to run the program.

SCP answer

The OP mentioned SCP, so here's that.

As others have pointed out, SFTP is a confusing since the upload syntax is completely different from the download syntax. It gets marginally easier to remember if you use the same form:

echo 'put LOCALPATH REMOTEPATH' | sftp USER@HOST
echo 'get REMOTEPATH LOCALPATH' | sftp USER@HOST

In reality, this is still a mess, and is why people still use "outdated" commands such as SCP:

scp USER@HOST:REMOTEPATH LOCALPATH
scp LOCALPATH USER@HOST:REMOTEPATH

SCP is secure but dated. It has some bugs that will never be fixed, namely crashing if the server's .bash_profile emits a message. However, in terms of usability, the devs were years ahead.

You seem to misunderstand the box model - in CSS you provide points for the top and left and then width and height - these are all that are needed for a box to be placed with exact measurements.

The width property is what your C-D is, but it is also what A-B is. If you omit it, the div will not have a defined width and the width will be defined by its contents.

Update (following the comments on the question:

Add a border-bottom-style: none; to your CSS to remove this style from the bottom only.

Use btoa("yourstring")

more info: https://developer.mozilla.org/en/docs/Web/API/WindowBase64/Base64_encoding_and_decoding

TypeScript is a superset of Javascript, it can use existing Javascript libraries and web APIs

The first question is what are your needs? UTF-8 encoding is a pretty good compromise between taking text created with a cheap editor and support for a wide variety of languages. In regards to the browser identifying the encoding, the response (from the web server) should tell the browser the encoding. Still most browsers will attempt to guess, because this is either missing or wrong in so many cases. They guess by reading some amount of the result stream to see if there is a character that does not fit in the default encoding. Currently all browser(? I did not check this, but it is pretty close to true) use utf-8 as the default.

So use utf-8 unless you have a compelling reason to use one of the many other encoding schemes.

This way you will be able to send ZPL to a printer no matter how it is connected (LPT, USB, Network Share...)

Call the print method:

private void BtnPrint_Click(object sender, System.EventArgs e)
{
    string s = "^XA^LH30,30\n^FO20,10^ADN,90,50^AD^FDHello World^FS\n^XZ";

    PrintDialog pd  = new PrintDialog();
    pd.PrinterSettings = new PrinterSettings();
    if(DialogResult.OK == pd.ShowDialog(this))
    {
        RawPrinterHelper.SendStringToPrinter(pd.PrinterSettings.PrinterName, s);
    }
}

There are 2 gotchas I've come across that happen when you're sending txt files with ZPL codes to the printer:

1. The file has to end with a new line character

2. Encoding has to be set to Encoding.Default when reading ANSI txt files with special characters

   public static bool SendTextFileToPrinter(string szFileName, string printerName)
   {
       var sb = new StringBuilder();
   
       using (var sr = new StreamReader(szFileName, Encoding.Default))
       {
           while (!sr.EndOfStream)
           {
               sb.AppendLine(sr.ReadLine());
           }
       }
   
       return RawPrinterHelper.SendStringToPrinter(printerName, sb.ToString());
   }
   

Something like this substitutions will be needed for your tables and field names.

Declare @TableUsers Table (User_ID, MyRowCount Int Identity(1,1)
Declare @i Int, @MaxI Int, @UserID nVarchar(50)

Insert into @TableUser
Select User_ID
From Users 
Where (My Criteria)
Select @MaxI = @@RowCount, @i = 1

While @i <= @MaxI
Begin
Select @UserID = UserID from @TableUsers Where MyRowCount = @i
Exec prMyStoredProc @UserID
Select

 @i = @i + 1, @UserID = null
End

Pretty sure you could've made that into a three line example. :)

If you want exact precision, use BigDecimal. Otherwise, you can use ints multiplied by 10 ^ whatever precision you want.

Execute this: npm install-test

You can use include/include_once or require/require_once

require_once('class.php');

Alternatively, use autoloading by adding to page.php

<?php 
function my_autoloader($class) {
    include 'classes/' . $class . '.class.php';
}

spl_autoload_register('my_autoloader');

$vars = new IUarts(); 
print($vars->data);    
?>

It also works adding that __autoload function in a lib that you include on every file like utils.php.

There is also this post that has a nice and different approach.

Efficient PHP auto-loading and naming strategies

Try

<p:panelGrid styleClass="ui-noborder">

If you can guarantee the 7-zip app will be installed (and in the path) on all target machines, you can offload by calling the command line app 7z. Not the most elegant solution but it is the least work.

There are two directories that looks like JDK.

  C:\Program Files\Java\jdk1.7.0_02
  C:\Program Files (x86)\Java\jdk1.7.0_02\

This may be due to both 64 bit and 32 bit JDK installed? What ever may be the case, the java.exe seen by ant.bat should from the JDK. If the JRE's java.exe comes first in the path, that will be used to guess the JDK location.

Put 'C:\Program Files (x86)\Java\jdk1.7.0_02\bin' or 'C:\Program Files\Java\jdk1.7.0_02' as the first argument in the path.

Further steps:

You can take output of ant -diagnostics and look for interesting keys. (assuming Sun/Oracle JDK).

 java.class.path 
 java.library.path
 sun.boot.library.path

(in my case tools.jar appears in java.class.path)

The host should be specified in each environment's config file. Eg:

config/environments/development.rb

See this question and this question.

i don't know if it's the answer to your question but you can try setting the background color in the xml layout like this. It is easy, it always works

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

 android:background="0xfff00000"

  >


<TextView

    android:id="@+id/text_view"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:text="@string/hello"

    />



</LinearLayout>

You can also do more fancy things with backgrounds by creating an xml background file with gradients which are cool and semi transparent, and refer to it for other use see example below:

the background.xml layout

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape>
        <gradient
            android:angle="90"
            android:startColor="#f0000000"
            android:endColor="#ff444444"
            android:type="linear" />
    </shape>
</item>
</selector>

your layout

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

 android:background="@layout/background"


    >


<TextView

    android:id="@+id/text_view"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:text="@string/hello"

    />



</LinearLayout>

In my case the separator was not the default "," but Tab.

pd.read_csv(file_name.csv, sep='\\t',lineterminator='\\r', engine='python', header='infer')

Note: "\t" did not work as suggested by some sources. "\\t" was required.

In this case a relatively simple GROUP BY can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER():

I'm also a stranger to windows cmd, but try this:

echo %%~nf

bool isPrime(int n) {
if(n <= 3)
    return (n > 1)==0? false: true;
else if(n%2 == 0 || n%3 == 0)
    return false;

int i = 5;

while(i * i <= n){
    if(n%i == 0 || (n%(i+2) == 0))
        return false;
    i = i + 6;
}

return true;
}

for any number, the minimum iterations to check if the number is prime or not can be from 2 to square root of the number. To reduce the iterations, even more, we can check if the number is divisible by 2 or 3 as maximum numbers can be eliminated by checking if the number is divisible by 2 or 3. Further any prime number greater than 3 can be expressed as 6k+1 or 6k-1. So the iteration can go from 6k+1 to the square root of the number.

Sure, a div can have as many classes as you want (this is both regarding to bootstrap and HTML in general):

<div class="active dropdown-toggle"></div>

Just separate the classes by space.

Also: Keep in mind some bootstrap classes are supposed to be used for the same stuff but in different cases (for example alignment classes, you might want something aligned left, right or center, but it has to be only one of them) and you shouldn't use them together, or you'd get an unexpected result, basically what will happen is that the class with the highest specificity will be the one applied (or if they have the same then it'll be the one that's defined last on the CSS). So you better avoid doing stuff like this:

<p class="text-center text-left">Some text</p>

Another easier way to do it is to upload your file to google sheets, then add a pivot, for the columns and rows select the same as you would with Excel, however, for values select Calculated Field and then in the formula type in =

The solution involved putting the gtest source directory as a subdirectory of your project. I've included the working CMakeLists.txt below if it is helpful to anyone.

cmake_minimum_required(VERSION 2.6)
project(basic_test)

################################
# GTest
################################
ADD_SUBDIRECTORY (gtest-1.6.0)
enable_testing()
include_directories(${gtest_SOURCE_DIR}/include ${gtest_SOURCE_DIR})

################################
# Unit Tests
################################
# Add test cpp file
add_executable( runUnitTests testgtest.cpp )
# Link test executable against gtest & gtest_main
target_link_libraries(runUnitTests gtest gtest_main)
add_test( runUnitTests runUnitTests )

How do we merge the master branch into the feature branch? Easy:

git checkout feature1
git merge master

There is no point in forcing a fast forward merge here, as it cannot be done. You committed both into the feature branch and the master branch. Fast forward is impossible now.

Have a look at GitFlow. It is a branching model for git that can be followed, and you unconsciously already did. It also is an extension to Git which adds some commands for the new workflow steps that do things automatically which you would otherwise need to do manually.

So what did you do right in your workflow? You have two branches to work with, your feature1 branch is basically the "develop" branch in the GitFlow model.

You created a hotfix branch from master and merged it back. And now you are stuck.

The GitFlow model asks you to merge the hotfix also to the development branch, which is "feature1" in your case.

So the real answer would be:

git checkout feature1
git merge --no-ff hotfix1

This adds all the changes that were made inside the hotfix to the feature branch, but only those changes. They might conflict with other development changes in the branch, but they will not conflict with the master branch should you merge the feature branch back to master eventually.

Be very careful with rebasing. Only rebase if the changes you did stayed local to your repository, e.g. you did not push any branches to some other repository. Rebasing is a great tool for you to arrange your local commits into a useful order before pushing it out into the world, but rebasing afterwards will mess up things for the git beginners like you.

The postgres:9.4 image you've inherited from declares a volume at /var/lib/postgresql/data. This essentially means you can't copy any files to that path in your image; the changes will be discarded.

You have a few choices:

• You could just add your own configuration files as a volume at run-time with docker run -v postgresql.conf:/var/lib/postgresql/data/postgresql.conf .... However, I'm not sure exactly how that will interact with the existing volume.

• You could copy the file over when the container is started. To do that, copy your file into the build at a location which isn't underneath the volume then call a script from the entrypoint or cmd which will copy the file to correct location and start postgres.

• Clone the project behind the Postgres official image and edit the Dockerfile to add your own config file in before the VOLUME is declared (anything added before the VOLUME instruction is automatically copied in at run-time).

• Pass all config changes in command option in docker-compose file

like:

services:
  postgres:
    ...  
    command:
      - "postgres"
      - "-c"
      - "max_connections=1000"
      - "-c"
      - "shared_buffers=3GB"
      - "-c"
      ...

Just write

Select id,name,age
From Student
Where age < 15
Union
Select id,name,age
From Student
Where Name like "%a%"
Order by name

the order by is applied to the complete resultset

just add 'checked="checked"' in the correct radio button that you would like it to be default on. As example you could use php quick if notation to add that in:

<input type="radio" name="sex" value="Male" size="17" <?php echo($isMale?'checked="checked"':''); ?>>Male
<input type="radio" name="sex" value="Female" size="17" <?php echo($isFemale?'checked="checked"':''); ?>>Female

in this example $isMale & $isFemale is boolean values that you assign based on the value from your database.
