I have used the below methods to convert the JSON to XML

List <Item> items;
public void LoadJsonAndReadToXML() {
  using(StreamReader r = new StreamReader(@ "E:\Json\overiddenhotelranks.json")) {
    string json = r.ReadToEnd();
    items = JsonConvert.DeserializeObject <List<Item>> (json);
    ReadToXML();
  }
}

And

public void ReadToXML() {
  try {
    var xEle = new XElement("Items",
      from item in items select new XElement("Item",
        new XElement("mhid", item.mhid),
        new XElement("hotelName", item.hotelName),
        new XElement("destination", item.destination),
        new XElement("destinationID", item.destinationID),
        new XElement("rank", item.rank),
        new XElement("toDisplayOnFod", item.toDisplayOnFod),
        new XElement("comment", item.comment),
        new XElement("Destinationcode", item.Destinationcode),
        new XElement("LoadDate", item.LoadDate)
      ));

    xEle.Save("E:\\employees.xml");
    Console.WriteLine("Converted to XML");
  } catch (Exception ex) {
    Console.WriteLine(ex.Message);
  }
  Console.ReadLine();
}

I have used the class named Item to represent the elements

public class Item {
  public int mhid { get; set; }
  public string hotelName { get; set; }
  public string destination { get; set; }
  public int destinationID { get; set; }
  public int rank { get; set; }
  public int toDisplayOnFod { get; set; }
  public string comment { get; set; }
  public string Destinationcode { get; set; }
  public string LoadDate { get; set; }
}

It works....

You can use IPython.display.clear_output to clear the output of a cell.

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print("Hello World!")

At the end of this loop you will only see one Hello World!.

Without a code example it's not easy to give you working code. Probably buffering the latest n events is a good strategy. Whenever the buffer changes you can clear the cell's output and print the buffer again.

import org.apache.commons.io.filefilter.WildcardFileFilter;

.........
.........

File dir = new File(fileDir);
FileFilter fileFilter = new WildcardFileFilter("*.txt");
File[] files = dir.listFiles(fileFilter);

The code above works great for me

You can use Math:

int x = Math.abs(-5);

I prefer to use the @ symbol so I see the query exactly as I can copy and paste into a query file:

string name = "Joe";
string gender = "M";
string query = String.Format(@"
SELECT
   *
FROM
   tableA
WHERE
   Name = '{0}' AND
   Gender = '{1}'", name, gender);

It's really great with long complex queries. Nice thing is it keeps tabs and line feeds so pasting into a query browser retains the nice formatting

Updates regarding answers suggesting using The Apache Commons Lang's: StringEscapeUtils.unescapeJava() - it was deprecated,

Deprecated. as of 3.6, use commons-text StringEscapeUtils instead

The replacement is Apache Commons Text's StringEscapeUtils.unescapeJava()

wmic can call an uninstaller. I haven't tried this, but I think it might work.

wmic /node:computername /user:adminuser /password:password product where name="name of application" call uninstall

If you don't know exactly what the program calls itself, do

wmic product get name | sort

and look for it. You can also uninstall using SQL-ish wildcards.

wmic /node:computername /user:adminuser /password:password product where "name like '%j2se%'" call uninstall

... for example would perform a case-insensitive search for *j2se* and uninstall "J2SE Runtime Environment 5.0 Update 12". (Note that in the example above, %j2se% is not an environment variable, but simply the word "j2se" with a SQL-ish wildcard on each end. If your search string could conflict with an environment or script variable, use double percents to specify literal percent signs, like %%j2se%%.)

If wmic prompts for y/n confirmation before completing the uninstall, try this:

echo y | wmic /node:computername /user:adminuser /password:password product where name="whatever" call uninstall

... to pass a y to it before it even asks.

I haven't tested this, but it's worth a shot anyway. If it works on one computer, then you can just loop through a text file containing all the computer names within your organization using a for loop, or put it in a domain policy logon script.

var str = 'Dude, he totally said that "You Rock!"';
var var1 = str.replace(/\"/g,"\\\"");
alert(var1);

Solution:

To your secondary question

var elem1 = $('#elem1'),
    elem2 = $('#elem2'),
    elem3 = $('#elem3');

You can use the variable as the replacement of selector.

elem1.css({'display':'none'}); //will work

In the below case selector is already stored in a variable.

$(elem1,elem2,elem3).css({'display':'none'}); // will not work

You can select every column from that sub-query by aliasing it and adding the alias before the *:

SELECT t.*, a+b AS total_sum
FROM
(
   SELECT SUM(column1) AS a, SUM(column2) AS b
   FROM table
) t

Another thing that people may find useful when using the develop method is the --user option to install without sudo. Ex:

python setup.py develop --user

instead of

sudo python setup.py develop

If the log indicates java.lang.UnsupportedClassVersionError: JVM**** bad major version.

Then the code and server is not compiled with the same JDK version.

To fix this, please switch the JDK version either in code or server JDK.

Try this:- In the below use case, im switching to 1.7_64 (JDK 1.7 64 bit)

c:\IBM\WebSphere\WSRR\v8.5\bin\managesdk.bat -enableProfile -profileName WSRRSrv01 -sdkname 1.7_64

Why are you sending it through a post if you already have it on the server (PHP) side?

Why not just save the array to the $_SESSION variable so you can use it when the form gets submitted, that might make it more "secure" since then the client cannot change the variables by editing the source.

It will depend upon how you really want to do.

I went off of peter.petrov's answer but let me explain where you make the file edits to change it to a relative path.

Simply edit "AXLAPIService.java" and change

url = new URL("file:C:users..../schema/current/AXLAPI.wsdl");

to

url = new URL("file:./schema/current/AXLAPI.wsdl");

or where ever you want to store it.

You can still work on packaging the wsdl file into the meta-inf folder in the jar but this was the simplest way to get it working for me.

To compare two lists with the order preserved use,

assertThat(actualList, contains("item1","item2"));

You can use:

• double width = MediaQuery.of(context).size.width;
• double height = MediaQuery.of(context).size.height;

To get height just of SafeArea (for iOS 11 and above):

• var padding = MediaQuery.of(context).padding;
• double newheight = height - padding.top - padding.bottom;

sigma = sum(y*(x - mean)**2)

should be

sigma = np.sqrt(sum(y*(x - mean)**2))

This is my solution. From my point of view, you can not bypass the <a>.

Your problem is that the attribute selector doesn't start with a @.

Try this:

$('input[name="correctAnswer"]').attr('checked', false);

You could use below code:

DateTime creation = File.GetCreationTime(@"C:\test.txt");
DateTime modification = File.GetLastWriteTime(@"C:\test.txt");

Here is a class I use when writing services. I usually have an interactive screen that comes up when the service is not called. From there I use the class as needed. It allows for multiple named instances on the same machine -hence the InstanceID field

Sample Call

  IntegratedServiceInstaller Inst = new IntegratedServiceInstaller();
  Inst.Install("MySvc", "My Sample Service", "Service that executes something",
                    _InstanceID,
// System.ServiceProcess.ServiceAccount.LocalService,      // this is more secure, but only available in XP and above and WS-2003 and above
  System.ServiceProcess.ServiceAccount.LocalSystem,       // this is required for WS-2000
  System.ServiceProcess.ServiceStartMode.Automatic);
  if (controller == null)
  {
    controller = new System.ServiceProcess.ServiceController(String.Format("MySvc_{0}", _InstanceID), ".");
                }
                if (controller.Status == System.ServiceProcess.ServiceControllerStatus.Running)
                {
                    Start_Stop.Text = "Stop Service";
                    Start_Stop_Debugging.Enabled = false;
                }
                else
                {
                    Start_Stop.Text = "Start Service";
                    Start_Stop_Debugging.Enabled = true;
                }

the recommended solution in the comments on the OpenSUSE distro suggests to change:

Defaults env_reset

to:

Defaults !env_reset

and then presumably to comment out the following line which isn't needed:

Defaults env_keep = "LANG LC_ADDRESS LC_CTYPE LC_COLLATE LC_IDENTIFICATION LC_MEASURE    MENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE LC_TIME LC_ALL L    ANGUAGE LINGUAS XDG_SESSION_COOKIE"

     $filelocation = "/pdf uplaod path/";
     $fileNL = $filelocation."/".$filename;

       $pdf->Output($fileNL,'F');

Here's a way to do it with LINQ to XML, complete with sample code:

Quickly Import and Export Excel Data with LINQ to XML

It's a little complex, since you have to import namespaces and so forth, but it does let you avoid any external dependencies.

(Also, of course, it's VB .NET, not C#, but you can always isolate the VB .NET stuff in its own project to use XML Literals, and do everything else in C#.)

Yes, first set a datetime to the start of the current month.

Second test if current date day > 25 and get a true/false on that. If True then add add one month to the start of month datetime object. If false then use the datetime object with the value set to the beginning of the month.

import datetime 
from dateutil.relativedelta import relativedelta

todayDate = datetime.date.today()
resultDate = todayDate.replace(day=1)

if ((todayDate - resultDate).days > 25):
    resultDate = resultDate + relativedelta(months=1)

print resultDate

If you want to pause then use java.util.concurrent.TimeUnit:

TimeUnit.SECONDS.sleep(1);

To sleep for one second or for 10 minutes

TimeUnit.MINUTES.sleep(10);

Or Thread Sleep

try        
{
    Thread.sleep(1000);
} 
catch(InterruptedException ex) 
{
    Thread.currentThread().interrupt();
}

see also the official documentation

TimeUnit.SECONDS.sleep() will call Thread.sleep. The only difference is readability and using TimeUnit is probably easier to understand for non obvious durations.

but if you want to solve your issue

        int timeToWait = 10; //second
        System.out.print("Scanning")
        try {
            for (int i=0; i<timeToWait ; i++) {
                Thread.sleep(1000);
                System.out.print(".")
            }
        } catch (InterruptedException ie)
        {
            Thread.currentThread().interrupt();
        }

People have suggested using INetAddress.isReachable. The problem is that some sites configure their firewalls to block ICMP Ping messages. So a "ping" might fail even though the web service is accessible.

And of course, the reverse is true as well. A host may respond to a ping even though the webserver is down.

And of course, a machine may be unable to connect directly to certain (or all) web servers due to local firewall restrictions.

The fundamental problem is that "can connect to the internet" is an ill-defined question, and this kind of thing is difficult to test without:

1. information on the user's machine and "local" networking environment, and
2. information on what the app needs to access.

So generally, the simplest solution is for an app to just try to access whatever it needs to access, and fall back on human intelligence to do the diagnosis.

Follow this one

$teacher_id = '';

        for ($i = 0; $i < count($data['teacher_id']); $i++) {

            $teacher_id .= $data['teacher_id'][$i].',';

        }
        $teacher_id = rtrim($teacher_id, ',');
        echo $teacher_id; exit;

This is a solution how to make autocomplete drop down list with VBA :

Firstly you need to insert a combo box into the worksheet and change its properties, and then running the VBA code to enable the autocomplete.

1. Get into the worksheet which contains the drop down list you want it to be autocompleted.

2. Before inserting the Combo box, you need to enable the Developer tab in the ribbon.

a). In Excel 2010 and 2013, click File > Options. And in the Options dialog box, click Customize Ribbon in the right pane, check the Developer box, then click the OK button.

b). In Outlook 2007, click Office button > Excel Options. In the Excel Options dialog box, click Popular in the right bar, then check the Show Developer tabin the Ribbon box, and finally click the OK button.

3. Then click Developer > Insert > Combo Box under ActiveX Controls.

4. Draw the combo box in current opened worksheet and right click it. Select Properties in the right-clicking menu.

5. Turn off the Design Mode with clicking Developer > Design Mode.

6. Right click on the current opened worksheet tab and click View Code.

7. Make sure that the current worksheet code editor is opened, and then copy and paste the below VBA code into it.

Code borrowed from extendoffice.com

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'Update by Extendoffice: 2018/9/21
    Dim xCombox As OLEObject
    Dim xStr As String
    Dim xWs As Worksheet
    Dim xArr



    Set xWs = Application.ActiveSheet
    On Error Resume Next
    Set xCombox = xWs.OLEObjects("TempCombo")
    With xCombox
        .ListFillRange = ""
        .LinkedCell = ""
        .Visible = False
    End With
    If Target.Validation.Type = 3 Then
        Target.Validation.InCellDropdown = False
        Cancel = True
        xStr = Target.Validation.Formula1
        xStr = Right(xStr, Len(xStr) - 1)
        If xStr = "" Then Exit Sub
        With xCombox
            .Visible = True
            .Left = Target.Left
            .Top = Target.Top
            .Width = Target.Width + 5
            .Height = Target.Height + 5
            .ListFillRange = xStr
            If .ListFillRange = "" Then
                xArr = Split(xStr, ",")
                Me.TempCombo.List = xArr
            End If
            .LinkedCell = Target.Address
        End With
        xCombox.Activate
        Me.TempCombo.DropDown
    End If
End Sub

Private Sub TempCombo_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
    Select Case KeyCode
        Case 9
            Application.ActiveCell.Offset(0, 1).Activate
        Case 13
            Application.ActiveCell.Offset(1, 0).Activate
    End Select
End Sub

9. Click File > Close and Return to Microsoft Excel to close the Microsoft Visual Basic for Application window.

10. Now, just click the cell with drop down list, you can see the drop-down list is displayed as a combo box, then type the first letter into the box, the corresponding word will be completed automatically.

Note: This VBA code is not applied to merged cells.

In KitKat you can use the Storage Access Framework.

Storage Access Framework / Writing a Client App

So many good answers here ;) Here is my approach. Similiar to eval() usage.

function functionExecutor(functionName, args){
    functionName.apply(this, args);
}

function showConfirmationDialog(html, functionYes, fYesArgs){
    $('#dialog').html(html);
    $('#dialog').dialog({
        buttons : [
            {
                text:'YES',
                click: function(){
                    functionExecutor(functionYes, fYesArgs);
                    $(this).dialog("close");
                },
                class:'green'
            },
            {
                text:'CANCEL',
                click: function() {
                    $(this).dialog("close");
                },
                class:'red'
            }
        ]
    });     
}

And the usage looks like:

function myTestYesFunction(arg1, arg2){
    alert("You clicked YES:"+arg1+arg2);
}

function toDoOrNotToDo(){
    showConfirmationDialog("Dialog text", myTestYesFunction, ['My arg 1','My arg 2']);
}

The simple answer is that you svn export the file instead of checking it out.

But that might not be what you want. You might want to work on the file and check it back in, without having to download GB of junk you don't need.

If you have Subversion 1.5+, then do a sparse checkout:

svn checkout <url_of_big_dir> <target> --depth empty
cd <target>
svn up <file_you_want>

For an older version of SVN, you might benefit from the following:

• Checkout the directory using a revision back in the distant past, when it was less full of junk you don't need.
• Update the file you want, to create a mixed revision. This works even if the file didn't exist in the revision you checked out.
• Profit!

An alternative (for instance if the directory has too much junk right from the revision in which it was created) is to do a URL->URL copy of the file you want into a new place in the repository (effectively this is a working branch of the file). Check out that directory and do your modifications.

I'm not sure whether you can then merge your modified copy back entirely in the repository without a working copy of the target - I've never needed to. If so then do that.

If not then unfortunately you may have to find someone else who does have the whole directory checked out and get them to do it. Or maybe by the time you've made your modifications, the rest of it will have finished downloading...

Others have answered sufficiently. I would just like to add a few examples of frequent extensions:

The main function returning void. This is not defined by the standard, meaning it will only work on some compilers (including GCC), but not on others. By the way, int main() and int main(int, char**) are the two signatures that the standard does define.

Another popular extension is being able to declare and define functions inside other functions:

void f()
{
    void g()
    {
       // ...
    }

    // ...
    g();
    // ...
}

This is nonstandard. If you want this kind of behavior, check out C++11 lambdas

You can use it inside of the shell to iterate over the next 20 results. Just type it if you see "has more" and you will see the next 20 items.

I personally have not found any command for the same. Just make a new component (renamed name) and copy paste the previous component's html, css, and ts. In ts obviously the class name would be replaced. Its the safest method but does take a little time.

%Started Program or Command% | taskkill /F /IM cmd.exe

Example:

notepad.exe | taskkill /F /IM cmd.exe

A dictionary is something like an array that's accessed by keys (e.g. strings,...) rather than just plain sequential numbers. It contains key/value pairs, you can look up values using a key like using a phone book: key=name, number=value.

For defining such a dictionary, you use this syntax using curly braces, see also: http://wiki.python.org/moin/SimplePrograms

You gave a condition ID (>79 and < 296) then the answer is:

delete from tab
where id > 79 and id < 296

this is the same as:

delete from tab
where id between 80 and 295

if id is an integer.

All answered:

delete from tab
where id between 79 and 296

this is the same as:

delete from tab
where id => 79 and id <= 296

Mind the difference.

if you are getting id from url try

$id = (isset($_GET['id']) ? $_GET['id'] : '');

if getting from form you need to use POST method cause your form has method="post"

 $id = (isset($_POST['id']) ? $_POST['id'] : '');

For php notices use isset() or empty() to check values exist or not or initialize variable first with blank or a value

$id= '';

You need to use view's layer to set border property. e.g:

#import <QuartzCore/QuartzCore.h>
...
view.layer.borderColor = [UIColor redColor].CGColor;
view.layer.borderWidth = 3.0f;

You also need to link with QuartzCore.framework to access this functionality.

You can use JavaScript as well, in case the textfield is dithered.

WebDriver driver=new FirefoxDriver();
driver.get("http://localhost/login.do");
driver.manage().window().maximize();
RemoteWebDriver r=(RemoteWebDriver) driver;
String s1="document.getElementById('username').value='admin'";
r.executeScript(s1);

This worked for me:

SELECT user, time FROM 
(
    SELECT user, time FROM lms_attendance --where clause
) AS T 
WHERE (SELECT COUNT(0) FROM table WHERE user = T.user AND time > T.time) = 0
ORDER BY user ASC, time DESC

Some awk version.

awk '/19:55/{c=5} c-->0'
awk '/19:55/{c=5} c && c--'

When pattern found, set c=5
If c is true, print and decrease number of c

@echo off
@color 0A

echo Deleting logs

rmdir /S/Q c:\log\

ping 1.1.1.1 -n 5 -w 1000 > nul

echo Adding log folder back

md c:\log\

You was on the right track. Just add code to add the folder which is deleted back again.

I had the same problem and could not mount system as read/write. It would return

Usage: mount [-r] [-w] [-o options] [-t type] device directory

Or

operation not permitted. Access denied

Now this works on all rooted devices.

DO THE FOLLOWING IN TERMINAL EMULATOR OR IN ADB SHELL

$ su
#mount - o rw,remount -t yaffs2 /system

Yaffs2 is the type of system partition. Replace it by the type of your system partition as obtained from executing the following

#cat /proc/mounts

Then check where /system is appearing from the lengthy result

Extract of mine was like

mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0/dev/block/platform/msm_sdcc.3/by-num/p10 /system ext4 ro,relatime,data=ordered 0 0
/dev/block/platform/msm_sdcc.3/by-num/p11 /cache ext4 rw,nosuid,nodev,relatime,data=ordered 0 0

So my system is ext4. And my command was

$ su
#mount  -o  rw,remount  -t  ext4  /system 

Done.

I had a similar error (connecting to MYSQL on aws via MYSql Workbench). I used to connect fine before and all of a sudden it stopped working and just wouldn't work again). My connection was via SSH protected by keyfile.

Turns out I was timing out. So I increased the SQL connection timeout to 30 secs (from default 10) and was good to go again. things to try (if you're in a similar setup)

1. Can you ssh directly from terminal to the server (detects issues with key file permissions etc)?
2. Can you then through terminal connect to MySQL with the same user/pwd using something like mysql -u [username] -p [database]? This will check for user rights issues etc.
3. if both of those work then your parameters are not the problem and maybe same timeout issue like me (except it never said timeout error, but rather asked to check for permissions etc)

Looking at posted answers I think this code would be also an alternative for someone. Nobody above used .Shapes.AddPicture in their code, only .Pictures.Insert()

Dim myPic As Object
Dim picpath As String

picpath = "C:\Users\photo.jpg" 'example photo path

Set myPic = ws.Shapes.AddPicture(picpath, False, True, 20, 20, -1, -1)

With myPic
    .Width = 25
    .Height = 25
    .Top = xlApp.Cells(i, 20).Top 'according to variables from correct answer
    .Left = xlApp.Cells(i, 20).Left
    .LockAspectRatio = msoFalse
End With

I'm working in Excel 2013. Also realized that You need to fill all the parameters in .AddPicture, because of error "Argument not optional". Looking at this You may ask why I set Height and Width as -1, but that doesn't matter cause of those parameters are set underneath between With brackets.

Hope it may be also useful for someone :)

The way I use it is

# Have to assign back to dataframe (because it is a new copy)
df = df.some_operation(inplace=False) 

Or

# No need to assign back to dataframe (because it is on the same copy)
df.some_operation(inplace=True)

CONCLUSION:

 if inplace is False
      Assign to a new variable;
 else
      No need to assign

Because you can break out of a do/while loop, let us "do" one round. With a while(false) at the end, the condition is never true and will not repeat, again.

do
{
    $subjectText = trim(filter_input(INPUT_POST, 'subject'));
    if(!$subjectText)
    {
        $smallInfo = 'Please give a subject.';
        break;
    }

    $messageText = trim(filter_input(INPUT_POST, 'message'));
    if(!$messageText)
    {
        $smallInfo = 'Please supply a message.';
        break;
    }
} while(false);

UserDefault+Helper.swift

import UIKit

private enum Defaults: String {
   case countryCode = "countryCode"
   case userloginId   = "userloginid"
}

final class UserDefaultHelper {

static var countryCode: String? {
    set{
        _set(value: newValue, key: .countryCode)
    } get {
        return _get(valueForKay: .countryCode) as? String ?? ""
    }
}

static var userloginId: String? {
    set{
        _set(value: newValue, key: .userloginId)
    } get {
        return _get(valueForKay: .userloginId) as? String ?? ""

Fetch Value:

let userloginid = UserDefaultHelper.userloginId

Delete Value:

UserDefaultHelper.deleteUserLoginId()

I was having the same problem with the AND() breaking the conditional formatting. I just happened to try treating the AND as multiplication, and it works! Remove the AND() function and just multiply your arguments. Excel will treat the booleans as 1 for true and 0 for false. I just tested this formula and it seems to work.

=(INDIRECT(ADDRESS(4,COLUMN()))>=INDIRECT(ADDRESS(ROW(),4)))*(INDIRECT(ADDRESS(4,COLUMN()))<=INDIRECT(ADDRESS(ROW(),5)))

I thought I would contribute by providing a concrete example of the practical use of the scale function. Say you have 3 test scores (Math, Science, and English) that you want to compare. Maybe you may even want to generate a composite score based on each of the 3 tests for each observation. Your data could look as as thus:

student_id <- seq(1,10)
math <- c(502,600,412,358,495,512,410,625,573,522)
science <- c(95,99,80,82,75,85,80,95,89,86)
english <- c(25,22,18,15,20,28,15,30,27,18)
df <- data.frame(student_id,math,science,english)

Obviously it would not make sense to compare the means of these 3 scores as the scale of the scores are vastly different. By scaling them however, you have more comparable scoring units:

z <- scale(df[,2:4],center=TRUE,scale=TRUE)

You could then use these scaled results to create a composite score. For instance, average the values and assign a grade based on the percentiles of this average. Hope this helped!

Note: I borrowed this example from the book "R In Action". It's a great book! Would definitely recommend.

public static String fillString(int count,char c) {
    StringBuilder sb = new StringBuilder( count );
    for( int i=0; i<count; i++ ) {
        sb.append( c ); 
    }
    return sb.toString();
}

What is wrong?

• How to change any string date to object date (also with moment.js):

let startDate = "2019-01-16T20:00:00.000"; let endDate = "2019-02-11T20:00:00.000"; let sDate = new Date(startDate); let eDate = new Date(endDate);

• with moment.js:

startDate = moment(sDate); endDate = moment(eDate);

Note that another approach is to keep with the 4.0 validation behaviour, but to define your own class that derives from RequestValidator and set:

<httpRuntime requestValidationType="YourNamespace.YourValidator" />

(where YourNamespace.YourValidator is well, you should be able to guess...)

This way you keep the advantages of 4.0s behaviour (specifically, that the validation happens earlier in the processing), while also allowing the requests you need to let through, through.

    <select name="career" id="career" onchange="location = this.value;">
        <option value="resume" selected> All Applications </option>
        <option value="resume&j=14">Seo Expert</option>
        <option value="resume&j=21">Project Manager</option>
        <option value="resume&j=33">Php Developer</option>
    </select>

Use

[A-Z]?

to make the letter optional. {1} is redundant. (Of course you could also write [A-Z]{0,1} which would mean the same, but that's what the ? is there for.)

You could improve your regex to

^([0-9]{5})+\s+([A-Z]?)\s+([A-Z])([0-9]{3})([0-9]{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])[0-9]{3}([0-9]{4})([0-9]{2})([0-9]{2})

And, since in most regex dialects, \d is the same as [0-9]:

^(\d{5})+\s+([A-Z]?)\s+([A-Z])(\d{3})(\d{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])\d{3}(\d{4})(\d{2})(\d{2})

But: do you really need 11 separate capturing groups? And if so, why don't you capture the fourth-to-last group of digits?

EDIT 2 As always, the GC does a better job than I do at managing memory; any previous attempts at doing it myself were doomed to failure.

I faced similar problem on windows server 2012 STD 64 bit , my problem is resolved after updating windows with all available windows updates.

public class ReverseLinkedList {

    public static void main(String args[]){
        LinkedList<String> linkedList = new LinkedList<String>();
        linkedList.add("a");
        linkedList.add("b");
        linkedList.add("c");
        linkedList.add("d");
        linkedList.add("e");
        linkedList.add("f");
        System.out.println("Original linkedList:");
        for(int i = 0; i <=linkedList.size()-1; i++){

            System.out.println(" - "+ linkedList.get(i));

        }
        LinkedList<String> reversedlinkedList = reverse(linkedList);
        System.out.println("Reversed linkedList:");
        for(int i = 0; i <=reversedlinkedList.size()-1; i++){
            System.out.println(" - "+ reversedlinkedList.get(i));

        }
    }

    public static LinkedList<String> reverse(LinkedList<String> linkedList){

        for(int i = 0; i < linkedList.size()/2; i++){
            String temp = linkedList.get(i);
            linkedList.set(i, linkedList.get(linkedList.size()-1-i));
            linkedList.set((linkedList.size()-1-i), temp);
        }
        return linkedList;
    }
}

I do this without external libaries:

var yourArray = ['aaa','bbb','ccc'];
var counter = [];

yourArray.forEach(function(name){
    conn.collection(name).drop(function(err) {
        counter.push(true);
        console.log('dropped');
        if(counter.length === yourArray.length){
            console.log('all dropped');
        }
    });                
});

Though I am late to this post, just updating my findings. This answer is only for Mac OS X.

$ sed 's/new/
> /g' m1.json > m2.json
sed: 1: "s/new/
/g": unescaped newline inside substitute pattern

In the above command I tried with Shift+Enter to add new line which didn't work. So this time I tried with "escaping" the "unescaped newline" as told by the error.

$ sed 's/new/\
> /g' m1.json > m2.json 

Worked! (in Mac OS X 10.9.3)

First solution:

These settings

TEMPLATE_DIRS = (
    os.path.join(SETTINGS_PATH, 'templates'),
)

mean that Django will look at the templates from templates/ directory under your project.

Assuming your Django project is located at /usr/lib/python2.5/site-packages/projectname/ then with your settings django will look for the templates under /usr/lib/python2.5/site-packages/projectname/templates/

So in that case we want to move our templates to be structured like this:

/usr/lib/python2.5/site-packages/projectname/templates/template1.html
/usr/lib/python2.5/site-packages/projectname/templates/template2.html
/usr/lib/python2.5/site-packages/projectname/templates/template3.html

Second solution:

If that still doesn't work and assuming that you have the apps configured in settings.py like this:

INSTALLED_APPS = (
    'appname1',
    'appname2',
    'appname3',
)

By default Django will load the templates under templates/ directory under every installed apps. So with your directory structure, we want to move our templates to be like this:

/usr/lib/python2.5/site-packages/projectname/appname1/templates/template1.html
/usr/lib/python2.5/site-packages/projectname/appname2/templates/template2.html
/usr/lib/python2.5/site-packages/projectname/appname3/templates/template3.html

SETTINGS_PATH may not be defined by default. In which case, you will want to define it (in settings.py):

import os
SETTINGS_PATH = os.path.dirname(os.path.dirname(__file__))

This should do it:

[^\x00-\x7F]+

It matches any character which is not contained in the ASCII character set (0-127, i.e. 0x0 to 0x7F).

You can do the same thing with Unicode:

[^\u0000-\u007F]+

For unicode you can look at this 2 resources:

• Code charts list of Unicode ranges
• This tool to create a regex filtered by Unicode block.

I'm late to the party, but after facing this issue today, I found this answer to be very good:

String asciiName = Normalizer.normalize(unicodeName, Normalizer.Form.NFD)
    .replaceAll("[^\\p{ASCII}]", "");

Assuming you already have a JFrame to call this from:

JOptionPane.showMessageDialog(frame, "thank you for using java");

Just use the JSON.stringify method and pass it through as the "data" parameter for the $.ajax function, like follows:

$.ajax({
    type: "POST",
    url: "index.php",
    dataType: "json",
    data: JSON.stringify({ paramName: info }),
    success: function(msg){
        $('.answer').html(msg);
    }
});

You just need to make sure you include the JSON2.js file in your page...

It's not at all related to "tidyr" and "dplyr", but here's another option to consider: merged.stack from my "splitstackshape" package, V1.4.0 and above.

In June 2016 Instagram made most of the functionality of their API available only to applications that have passed a review process. They still however provide JSON data through the web interface, and you can add the parameter __a=1 to a URL to only include the JSON data.

max=
while :;do
  c=$(curl -s "https://www.instagram.com/username/?__a=1&max_id=$max")
  jq -r '.user.media.nodes[]?|.display_src'<<<"$c"
  max=$(jq -r .user.media.page_info.end_cursor<<<"$c")
  jq -e .user.media.page_info.has_next_page<<<"$c">/dev/null||break
done

Edit: As mentioned in the comment by alnorth29, the max_id parameter is now ignored. Instagram also changed the format of the response, and you need to perform additional requests to get the full-size URLs of images in the new-style posts with multiple images per post. You can now do something like this to list the full-size URLs of images on the first page of results:

c=$(curl -s "https://www.instagram.com/username/?__a=1")
jq -r '.graphql.user.edge_owner_to_timeline_media.edges[]?|.node|select(.__typename!="GraphSidecar").display_url'<<<"$c"
jq -r '.graphql.user.edge_owner_to_timeline_media.edges[]?|.node|select(.__typename=="GraphSidecar")|.shortcode'<<<"$c"|while read l;do
  curl -s "https://www.instagram.com/p/$l?__a=1"|jq -r '.graphql.shortcode_media|.edge_sidecar_to_children.edges[]?.node|.display_url'
done

To make a list of the shortcodes of each post made by the user whose profile is opened in the frontmost tab in Safari, I use a script like this:

sjs(){ osascript -e'{on run{a}','tell app"safari"to do javascript a in document 1',end} -- "$1";}

while :;do
  sjs 'o="";a=document.querySelectorAll(".v1Nh3 a");for(i=0;e=a[i];i++){o+=e.href+"\n"};o'>>/tmp/a
  sjs 'window.scrollBy(0,window.innerHeight)'
  sleep 1
done

Use array_walk_recursive function for multi-denominational array.

array_walk_recursive($data, function (&$v, $k) { 
    if($k == 'transaction_date'){ 
        $v = date('d/m/Y',$v); 
    } 
});

I prefer using HTTP Headers for this kind of contextual information.

For the total number of elements, I use the X-total-count header.
For links to next, previous page, etc. I use HTTP Link header:
http://www.w3.org/wiki/LinkHeader

Github does it the same way: https://developer.github.com/v3/#pagination

In my opinion, it's cleaner since it can be used also when you return content that doesn't support hyperlinks (i.e binaries, pictures).

We can define the so-called foreign key in MongoDB. However, we need to maintain the data integrity BY OURSELVES. For example,

student
{ 
  _id: ObjectId(...),
  name: 'Jane',
  courses: ['bio101', 'bio102']   // <= ids of the courses
}

course
{
  _id: 'bio101',
  name: 'Biology 101',
  description: 'Introduction to biology'
}

The courses field contains _ids of courses. It is easy to define a one-to-many relationship. However, if we want to retrieve the course names of student Jane, we need to perform another operation to retrieve the course document via _id.

If the course bio101 is removed, we need to perform another operation to update the courses field in the student document.

More: MongoDB Schema Design

The document-typed nature of MongoDB supports flexible ways to define relationships. To define a one-to-many relationship:

Embedded document

1. Suitable for one-to-few.
2. Advantage: no need to perform additional queries to another document.
3. Disadvantage: cannot manage the entity of embedded documents individually.

Example:

student
{
  name: 'Kate Monster',
  addresses : [
     { street: '123 Sesame St', city: 'Anytown', cc: 'USA' },
     { street: '123 Avenue Q', city: 'New York', cc: 'USA' }
  ]
}

Child referencing

Like the student/course example above.

Parent referencing

Suitable for one-to-squillions, such as log messages.

host
{
    _id : ObjectID('AAAB'),
    name : 'goofy.example.com',
    ipaddr : '127.66.66.66'
}

logmsg
{
    time : ISODate("2014-03-28T09:42:41.382Z"),
    message : 'cpu is on fire!',
    host: ObjectID('AAAB')       // Reference to the Host document
}

Virtually, a host is the parent of a logmsg. Referencing to the host id saves much space given that the log messages are squillions.

Solution for Python 3

For Python3 the following code grabs the word list from the web and returns a list. Answer based on accepted answer above by Kyle Kelley.

import urllib.request

word_url = "http://svnweb.freebsd.org/csrg/share/dict/words?view=co&content-type=text/plain"
response = urllib.request.urlopen(word_url)
long_txt = response.read().decode()
words = long_txt.splitlines()

Output:

>>> words
['a', 'AAA', 'AAAS', 'aardvark', 'Aarhus', 'Aaron', 'ABA', 'Ababa',
 'aback', 'abacus', 'abalone', 'abandon', 'abase', 'abash', 'abate',
 'abbas', 'abbe', 'abbey', 'abbot', 'Abbott', 'abbreviate', ... ]

And to generate (because it was my objective) a list of 1) upper case only words, 2) only "name like" words, and 3) a sort-of-realistic-but-fun sounding random name:

import random
upper_words = [word for word in words if word[0].isupper()]
name_words  = [word for word in upper_words if not word.isupper()]
rand_name   = ' '.join([name_words[random.randint(0, len(name_words))] for i in range(2)])

And some random names:

>>> for n in range(10):
        ' '.join([name_words[random.randint(0,len(name_words))] for i in range(2)])

    'Semiramis Sicilian'
    'Julius Genevieve'
    'Rwanda Cohn'
    'Quito Sutherland'
    'Eocene Wheller'
    'Olav Jove'
    'Weldon Pappas'
    'Vienna Leyden'
    'Io Dave'
    'Schwartz Stromberg'

try:
  #treat object as iterable
except TypeError, e:
  #object is not actually iterable

Don't run checks to see if your duck really is a duck to see if it is iterable or not, treat it as if it was and complain if it wasn't.

I don't think anything like that is built-in in Ruby. You can reopen String class and add to_bool method there:

class String
    def to_bool
        return true if self=="true"
        return false if self=="false"
        return nil
    end
end

Then you can use it anywhere in your project, like this: params[:internal].to_bool

Just a note which may be helpful- I was having this trouble with Apache on my laptop (which connects by wifi AFTER startup), and restarting the server (after connect) fixed the issue. I guess in my case this may be to do with apache starting offline and perhaps there noting that DNS lookups fail?

This works for me:

1) Stop the ng server

2) Reinstall your package

npm install your-package-name

3) Run all again

ng serve

Another Python BST with sort key (defaulting to value)

Try the following:

You'd think it would be yyyy-mm-dd but oh well :P

1- You need to save scroll position like this

rvProduct.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                recyclerViewState = rvProduct.getLayoutManager().onSaveInstanceState(); // save recycleView state
            }
        });

2- And after you call notifyDataSetChanged then onRestoreInstanceState like this example

productsByBrandAdapter.addData(productCompareList);
productsByBrandAdapter.notifyDataSetChanged();
rvProduct.getLayoutManager().onRestoreInstanceState(recyclerViewState); // restore recycleView state

In script is usefull something like this:

if [ ! -d /etc/nginx ]; then ln -s /usr/local/nginx/conf/ /etc/nginx > /dev/null 2>&1; fi

it prevents before re-create "bad" looped symlink after re-run script

you most specified in the file config key ssh:

# Default GitHub user
Host one
 HostName gitlab.com
 User git
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/key-one
 IdentitiesOnly yes

#two user
Host two
 HostName gitlab.com
 User git
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/key-two
 IdentitiesOnly yes

I suppose you can open Java files in Visual Studio and just use the command line tools directly. I don't think you'd get syntax highlighting or autocompletion though.

Eclipse is really not all that different from Visual Studio, and there are a lot of tools that are designed to make Android development more comfortable that work from within Eclipse.

Maybe I'm being dumb, but isn't table the obvious solution here?

<div class="parent">
    <div class="fixed">
    <div class="stretchToFit">
</div>

.parent{ display: table; width 100%; }
.fixed { display: table-cell; width: 150px; }
.stretchToFit{ display: table-cell; vertical-align: top}

Another way that I've figured out in chrome is even simpler, but man is it a hack!

.fixed{ 
   float: left
}
.stretchToFit{
   display: table-cell;
   width: 1%;
}

This alone should fill the rest of the line horizontally, as table-cells do. However, you get some strange issues with it going over 100% of its parent, setting the width to a percent value fixes it though.

Finally found this method:

basename($_SERVER['REQUEST_URI']);

This will return all URLs with page name. (e.g.: index.php?id=1&name=rr&class=10).

With git there is a https format

https://github.com/equivalent/we_demand_serverless_ruby.git

This format accepts User + password

https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git

So what you can do is create a new user that will be used just as a bot, add only enough permissions that he can just read the repository you want to load in NPM modules and just have that directly in your packages.json

 Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token

In Select Scopes part, check the on repo: Full control of private repositories

This is so that token can access private repos that user can see

Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)

You need to be sure to push this config only to private repo

Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)

// packages.json


{
  // ....
    "name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
  // ...
}

If you are working with ActionBarSherlock

In your theme add this:

<style name="MyTheme" parent="Theme.Sherlock">
    ....
    <item name="windowContentOverlay">@null</item>
    <item name="android:windowContentOverlay">@null</item>
    ....
</style>

This plugin works great for me.

Bootstrap 3 lightbox plugin

For me it was enough to reinstall whitelist plugin:

cordova plugin remove cordova-plugin-whitelist

and then

cordova plugin add cordova-plugin-whitelist

It looks like updating from previous versions of Cordova was not succesful.

You can use :

copy /b/v/y

See SS64 on COPY.

In jQuery 1.8, this can be done as follows:

(function($){
    $.fn.disableSelection = function() {
        return this
                 .attr('unselectable', 'on')
                 .css('user-select', 'none')
                 .on('selectstart', false);
    };
})(jQuery);

Remove the date() part

SELECT name, datum 
FROM tasks 
WHERE datum >= NOW()

and if you use a specific date, don't forget the quotes around it and use the proper format with :

SELECT name, datum 
FROM tasks 
WHERE datum >= '2014-05-18 15:00:00'

I had the same issue as all of our servers run older versions of MySQL. This can be solved by running a PHP script. Save this code to a file and run it entering the database name, user and password and it'll change the collation from utf8mb4/utf8mb4_unicode_ci to utf8/utf8_general_ci

<!DOCTYPE html>
<html>
<head>
  <title>DB-Convert</title>
  <style>
    body { font-family:"Courier New", Courier, monospace; }
  </style>
</head>
<body>

<h1>Convert your Database to utf8_general_ci!</h1>

<form action="db-convert.php" method="post">
  dbname: <input type="text" name="dbname"><br>
  dbuser: <input type="text" name="dbuser"><br>
  dbpass: <input type="text" name="dbpassword"><br>
  <input type="submit">
</form>

</body>
</html>
<?php
if ($_POST) {
  $dbname = $_POST['dbname'];
  $dbuser = $_POST['dbuser'];
  $dbpassword = $_POST['dbpassword'];

  $con = mysql_connect('localhost',$dbuser,$dbpassword);
  if(!$con) { echo "Cannot connect to the database ";die();}
  mysql_select_db($dbname);
  $result=mysql_query('show tables');
  while($tables = mysql_fetch_array($result)) {
          foreach ($tables as $key => $value) {
           mysql_query("ALTER TABLE $value CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci");
     }}
  echo "<script>alert('The collation of your database has been successfully changed!');</script>";
}

?>

Try this with the + after [0-9]:

input type="text" pattern="[0-9]+" title="number only"

The simplest solution is to add a :key attribute to :

<router-view :key="$route.fullPath"></router-view>

This is because Vue Router does not notice any change if the same component is being addressed. With the key, any change to the path will trigger a reload of the component with the new data.

Another alternative :

>>> mydict = {'a':1, 'b':2, 'c':3}
>>> import json

Then with python2 :

or with python 3 :

It looks like Microsoft invaded brains of all other respondents and made them write as complicated solutions as possible. Here is the simplest way without any additional functions/declare statements:

SELECT geography::Point(LATITUDE_1, LONGITUDE_1, 4326).STDistance(geography::Point(LATITUDE_2, LONGITUDE_2, 4326))

Simply substitute your data instead of LATITUDE_1, LONGITUDE_1, LATITUDE_2, LONGITUDE_2 e.g.:

SELECT geography::Point(53.429108, -2.500953, 4326).STDistance(geography::Point(c.Latitude, c.Longitude, 4326))
from coordinates c

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f3" action="#" >
                <input id="edit3" type="submit" name="edit" value="Edit">
               </form>

If you are working on a windows forms project you can try the following:

Add items to the ListBox as KeyValuePair objects:

listBox.Items.Add(new KeyValuePair(key, value);

Then you will be able to retrieve them the following way:

KeyValuePair keyValuePair = listBox.Items[index];
var value = keyValuePair.Value;

There is simpler approach to decode a ByteBuffer into a String without any problems, mentioned by Andy Thomas.

String s = StandardCharsets.UTF_8.decode(byteBuffer).toString();

You could simply use .rounded-circle bootstrap.

 <img class="rounded-circle" src="http://placekitten.com/g/200/200"/>

You can even specify the width and height of the rounded image by providing an inline style to the image, which overrides the default size.

 <img class="rounded-circle" style="height:100px; width: 100px" src="http://placekitten.com/g/200/200" />

I had the same problem a few weeks ago like yours; but I invented a brilliant solution for exchanging variables between PHP and JavaScript. It worked for me well:

1. Create a hidden form on a HTML page

2. Create a Textbox or Textarea in that hidden form

3. After all of your code written in the script, store the final value of your variable in that textbox

4. Use $_REQUEST['textbox name'] line in your PHP to gain access to value of your JavaScript variable.

I hope this trick works for you.

John Conde does all the right procedures in his method but doesn't satisfy the final step in your question which is to format the result to your specifications.

This code (Demo) will display the raw difference, expose the trouble with trying to immediately format the raw difference, display my preparation steps, and finally present the correctly formatted result:

$datetime1 = new DateTime('2017-04-26 18:13:06');
$datetime2 = new DateTime('2011-01-17 17:13:00');  // change the millenium to see output difference
$diff = $datetime1->diff($datetime2);

// this will get you very close, but it will not pad the digits to conform with your expected format
echo "Raw Difference: ",$diff->format('%y years %m months %d days %h hours %i minutes %s seconds'),"\n";

// Notice the impact when you change $datetime2's millenium from '1' to '2'
echo "Invalid format: ",$diff->format('%Y-%m-%d %H:%i:%s'),"\n";  // only H does it right

$details=array_intersect_key((array)$diff,array_flip(['y','m','d','h','i','s']));

echo '$detail array: ';
var_export($details);
echo "\n";

array_map(function($v,$k)
    use(&$r)
    {
        $r.=($k=='y'?str_pad($v,4,"0",STR_PAD_LEFT):str_pad($v,2,"0",STR_PAD_LEFT));
        if($k=='y' || $k=='m'){$r.="-";}
        elseif($k=='d'){$r.=" ";}
        elseif($k=='h' || $k=='i'){$r.=":";}
    },$details,array_keys($details)
);
echo "Valid format: ",$r; // now all components of datetime are properly padded

Output:

Raw Difference: 6 years 3 months 9 days 1 hours 0 minutes 6 seconds
Invalid format: 06-3-9 01:0:6
$detail array: array (
  'y' => 6,
  'm' => 3,
  'd' => 9,
  'h' => 1,
  'i' => 0,
  's' => 6,
)
Valid format: 0006-03-09 01:00:06

Now to explain my datetime value preparation:

$details takes the diff object and casts it as an array. array_flip(['y','m','d','h','i','s']) creates an array of keys which will be used to remove all irrelevant keys from (array)$diff using array_intersect_key().

Then using array_map() my method iterates each value and key in $details, pads its left side to the appropriate length with 0's, and concatenates the $r (result) string with the necessary separators to conform with requested datetime format.

^[^<>]+$

The caret in the character class ([^) means match anything but, so this means, beginning of string, then one or more of anything except < and >, then the end of the string.

There's another method called dump() which can also be used for logging:

func dump<T>(T, name: String?, indent: Int, maxDepth: Int, maxItems: Int)

Dumps an object’s contents using its mirror to standard output.

From Swift Standard Library Functions

This is my approach:

String[] columnNames = {"id", "Nome", "Sobrenome","Email"};

List<Student> students = _repo.getAll();

Object[][] data = new Object[students.size()][4];

int index = 0;
for(Student s : students) {
    data[index][0] = s.getId();
    data[index][1] = s.getFirstName();
    data[index][2] = s.getLastName();
    data[index][3] = s.getEmail();
    index++;
}

DefaultTableModel model = new DefaultTableModel(data, columnNames);

table = new JTable(model);

I just want to point out that two of the solutions offered previously,

• Drag and drop from Windows Explorer
• Show All Files and then include in project.

do not do what the question asked for:

Include in project while preserving the directory structure.

At least not in my case (C++/CLI project Visual Studio 2013 on Windows 7).

In Visual Studio, once you are back in the normal view (not Show All Files), the files you added are all listed at the top level of the project.

Yes, on disk they still reside where they were, but in Solution Explorer they are loose.

I did not find a way around it except recreating the directory structure in Solution Explorer and then doing Add Existing Items at the right location.

The query returned from the profiler or query object will have placeholders if you're using those.

To see the exact query run by mysql you can use the general query log.

This will list all the queries which have run since it was enabled. Don't forget to disable this once you've collected your sample. On an active server; this log can fill up very fast.

From a mysql terminal or query tool like MySQL Workbench run:

SET GLOBAL log_output = 'table';
SET GLOBAL general_log = 1;

then run your query. The results are stored in the "mysql.general_log" table.

SELECT * FROM mysql.general_log

To disable the query log:

SET GLOBAL general_log = 0;

To verify it's turned off:

SHOW VARIABLES LIKE 'general%';

This helped me locate a query where the placeholder wasn't being replaced by zend db. Couldn't see that with the profiler.

2020, Im using:

select {
    text-align: center;
    text-align-last: center;
    -moz-text-align-last: center;
}

As this is specifically tagged for jQuery -

$("#myElement")[0].getBoundingClientRect();

or

$("#myElement").get(0).getBoundingClientRect();

(These are functionally identical, in some older browsers .get() was slightly faster)

Note that if you try to get the values via jQuery calls then it will not take into account any css transform values, which can give unexpected results...

Note 2: In jQuery 3.0 it has changed to using the proper getBoundingClientRect() calls for its own dimension calls (see the jQuery Core 3.0 Upgrade Guide) - which means that the other jQuery answers will finally always be correct - but only when using the new jQuery version - hence why it's called a breaking change...

EDIT: Milhous's answer seems to be the officially supported way to do this as of 10.5. Earlier version of OS X and even 10.5 and up should still work using the following instructions though.

1. Open the command line (Terminal)

2. Navigate to your Eclipse installation folder, for instance:

   • cd /Applications/eclipse/
   • cd /Developer/Eclipse/Eclipse.app/Contents/MacOS/eclipse
   • cd /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse
   • cd /Users/<usernamehere>/eclipse/jee-neon/Eclipse.app/Contents/MacOS

3. Launch Eclipse: ./eclipse &

This last command will launch eclipse and immediately background the process.

Rinse and repeat to open as many unique instances of Eclipse as you want.

You might have to change the Tomcat server ports in order to run your project in different/multiple Tomcat instances, see Tomcat Server Error - Port 8080 already in use

Java 9

public static void main(String[] args) {
    Map<Integer,String> map = Map.ofEntries(entry(1,"A"), entry(2,"B"), entry(3,"C"));
}

<div style="height: 100px;"> </div>

OR

<div id="foo"/> and set the style as #foo { height: 100px; }
<div class="bar"/> and set the style as .bar{ height: 100px;  }

for i in range(5):

is the same as

for i in [0,1,2,3,4]:

For completeness (since this seems to be a high-traffic page), let's not forget the good old dir() function:

$entries = [];
$d = dir("/"); // dir to scan
while (false !== ($entry = $d->read())) { // mind the strict bool check!
    if ($entry[0] == '.') continue; // ignore anything starting with a dot
    $entries[] = $entry;
}
$d->close();
sort($entries); // or whatever desired

print_r($entries);

You can do it using namespaces, like this:

export namespace Library {
    export const BOOK_SHELF_NONE: string = 'NONE';
}

Then you can import it from anywhere else:

import {Library} from './Library';
console.log(Library.BOOK_SHELF_NONE);

If you need a class there as well include it inside the namespace: export class Book {...}

Use the Find method if item_manuf_id is a primary key:

var result = dtPs.Rows.Find("some value");

If you only want to know if the value is in there then use the Contains method.

if (dtPs.Rows.Contains("some value"))
{
  ...
}

Primary key restriction applies to Contains aswell.

make will do this for you. Investigate the -j and -l switches in the man page. I don't think g++ is parallelizable.

On Button click start the native video player which will open in full screen:

Intent intent = new Intent(Intent.ACTION_VIEW );
intent.setDataAndType(Uri.parse(path), "video/*");
startActivity(intent);

Either Collections.emptyMap(), or if type inference doesn't work in your case,
Collections.<String, String>emptyMap()

I assume I have import datetime before running each of the lines of code below

datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')

prints "01/25/13".

If you can't live with the leading zero, try this:

dt = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print '{0}/{1}/{2:02}'.format(dt.month, dt.day, dt.year % 100)

This prints "1/25/13".

EDIT: This may not work on every platform:

datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')

An empty string is a string with zero length or no character. Null is absence of data.

There is a trick in Solaris I have used, if you ask for the size of more than one file it returns just the total size with no names - so include an empty file like /dev/null as the second file:

eg command fileyouwant /dev/null

I can't rememebr which size command this works for ls/wc/etc - unfortunately I don't have a solaris box to test it.

You may try this:

foreach(var item in yourArray)
{
    Console.WriteLine(item.ToString());
}

Also you may want to try something like this:

yourArray.ToList().ForEach(i => Console.WriteLine(i.ToString()));

EDIT: to get output in one line [based on your comment]:

 Console.WriteLine("[{0}]", string.Join(", ", yourArray));
 //output style:  [8, 1, 8, 8, 4, 8, 6, 8, 8, 8]

EDIT(2019): As it is mentioned in other answers it is better to use Array.ForEach<T> method and there is no need to do the ToList step.

Array.ForEach(yourArray, Console.WriteLine);

I just wanted something really basic to move some files out of the main folder, like user2889485's reply, but his specific answer didnt work for me. I didnt care if they were in the same package or not.

My GOPATH workspace is c:\work\go and under that I have

/src/pg/main.go      (package main)
/src/pg/dbtypes.go   (pakage dbtypes)

Updated answer for Swift 4

let language = Bundle.main.preferredLocalizations.first

List<String> lines = Files.readAllLines(Paths.get("src/test/resources/foo.txt"));
lines.forEach(System.out::println);

Maybe try this:

yum -y groupinstall "MYSQL Database Client"

buckets = [0] * 100

Careful - this technique doesn't generalize to multidimensional arrays or lists of lists. Which leads to the List of lists changes reflected across sublists unexpectedly problem

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

M = 1.6
# Miles to Kilometers

# Gallons to liters Gallons = 3.6

Simple working camera app avoiding the null intent problem

- all changed code included in this reply; close to android tutorial

I've been spending plenty of time on this issue, so I decided to create an account and share my outcomes with you.

The official android tutorial "Taking Photos Simply" turned out to not quite hold what it promised. The code provided there did not work on my device: a Samsung Galaxy S4 Mini GT-I9195 running android version 4.4.2 / KitKat / API Level 19.

I figured out that the main problem was the following line in the method invoked when capturing the photo (dispatchTakePictureIntent in the tutorial):

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);

It resulted in the intent subsequently catched by onActivityResult being null.

To solve this problem, I pulled much inspiration out of earlier replies here and some helpful posts on github (mostly this one by deepwinter - big thanks to him; you might want to check out his reply on a closely related post as well).

Following these pleasant pieces of advice, I chose the strategy of deleting the mentioned putExtra line and doing the corresponding thing of getting back the taken picture from the camera within the onActivityResult() method instead. The decisive lines of code to get back the bitmap associated with the picture are:

        Uri uri = intent.getData();
        Bitmap bitmap = null;
        try {
            bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
        } catch (IOException e) {
            e.printStackTrace();
        }

I created an exemplary app which just has the ability to take a picture, save it on the SD card and display it. I think this might be helpful to people in the same situation as me when I stumbled on this issue, since the current help suggestions mostly refer to rather extensive github posts which do the thing in question but aren't too easy to oversee for newbies like me. With respect to the file system Android Studio creates per default when creating a new project, I just had to change three files for my purpose:

activity_main.xml :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.android.simpleworkingcameraapp.MainActivity">

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:onClick="takePicAndDisplayIt"
    android:text="Take a pic and display it." />

<ImageView
    android:id="@+id/image1"

// copied from the android development pages; just added a Toast to show the storage location
private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmm").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    if (intent.resolveActivity(getPackageManager()) != null) {
        File file = null;
        try {
            file = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File
        }

        startActivityForResult(intent, REQUEST_TAKE_PHOTO);
    }
}

@Override

    if (requestCode == REQUEST_TAKE_PHOTO && resultcode == RESULT_OK) {

        try {
            bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
        } catch (IOException e) {
            e.printStackTrace();
        }
        image.setImageBitmap(bitmap);
    }
}
}

AndroidManifest.xml :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.simpleworkingcameraapp">


<!--only added paragraph-->
<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  <!-- only crucial line to add; for me it still worked without the other lines in this paragraph -->
<uses-permission android:name="android.permission.CAMERA" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

Note that the solution I found for the problem also led to a simplification of the android manifest file: the changes suggested by the android tutorial in terms of adding a provider are no longer needed since I am not making use of any in my java code. Hence, only few standard lines -mostly regarding permissions- had to be added to the manifest file.

It might additionally be valuable to point out that Android Studio's autoimport may not be capable of handling java.text.SimpleDateFormat and java.util.Date. I had to import both of them manually.

Make sure the outermost div has the following CSS properties:

.outer {
  /* ... */
  height: auto;
  overflow: hidden;
  /* ... */
}

If you need a simple working solution, try using DefaultTableModel.

If you have created your own table model, that extends AbstractTableModel, then you should also implement removeRow() method. The exact implementation depends on the underlying structure, that you have used to store data.

For example, if you have used Vector, then it may be something like this:

public class SimpleTableModel extends AbstractTableModel {
    private Vector<String> columnNames = new Vector<String>();
    // Each value in the vector is a row; String[] - row data;
    private Vector<String[]> data = new Vector<String[]>();

    ...

    public String getValueAt(int row, int col) {
        return data.get(row)[col];
    }

    ...

    public void removeRow(int row) {
        data.removeElementAt(row);
    }
}

If you have used List, then it would be very much alike:

// Each item in the list is a row; String[] - row data;
List<String[]> arr = new ArrayList<String[]>();

public void removeRow(int row) {
    data.remove(row);
}

HashMap:

//Integer - row number; String[] - row data;
HashMap<Integer, String[]> data = new HashMap<Integer, String[]>();

public void removeRow(Integer row) {
    data.remove(row);
}

And if you are using arrays like this one

String[][] data = { { "a", "b" }, { "c", "d" } };

then you're out of luck, because there is no way to dynamically remove elements from arrays. You may try to use arrays by storing separately some flags notifying which rows are deleted and which are not, or by some other devious way, but I would advise against it... That would introduce unnecessary complexity, and would in fact just be solving a problem by creating another. That's a sure-fire way to end up here. Try one of the above ways to store your table data instead.

For better understanding of how this works, and what to do to make your own model work properly, I strongly advise you to refer to Java Tutorial, DefaultTableModel API and it's source code.

To disable link to access another page on touch device:

if (control == false)
  document.getElementById('id_link').setAttribute('href', '#');
else
  document.getElementById('id_link').setAttribute('href', 'page/link.html');
end if;

Try

xargs -n2  printf "%-20s%s\n"

or even

xargs printf "%-20s%s\n"

if input is not very large.

You can submit your jsp page to servlet. For this use <form> tag.

And to redirect use:

response.sendRedirect("servleturl")

Just thought I'd something that might help you in the future. To search multiple string and output line numbers and browse thru the output, type:

egrep -ne 'null|three'

will show:

2:example two null,  
3:example three,  
4:example four null,   

egrep -ne 'null|three' | less

will display output in a less session

the secure way is encrypt your sensitive data by AES and the encryption key is derivation by password-based key derivation function (PBE), the master password used to encrypt/decrypt the encrypt key for AES.

master password -> secure key-> encrypt data by the key

You can use pbkdf2

from PBKDF2 import PBKDF2
from Crypto.Cipher import AES
import os
salt = os.urandom(8)    # 64-bit salt
key = PBKDF2("This passphrase is a secret.", salt).read(32) # 256-bit key
iv = os.urandom(16)     # 128-bit IV
cipher = AES.new(key, AES.MODE_CBC, iv)

make sure to store the salt/iv/passphrase , and decrypt using same salt/iv/passphase

Weblogic used similar approach to protect passwords in config files

One issue is that reindex will fail if there are duplicate values. Say we're working with timestamped data, which we want to index by date:

df = pd.DataFrame({
    'timestamps': pd.to_datetime(
        ['2016-11-15 1:00','2016-11-16 2:00','2016-11-16 3:00','2016-11-18 4:00']),
    'values':['a','b','c','d']})
df.index = pd.DatetimeIndex(df['timestamps']).floor('D')
df

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-18  "2016-11-18 04:00:00"  d

Due to the duplicate 2016-11-16 date, an attempt to reindex:

all_days = pd.date_range(df.index.min(), df.index.max(), freq='D')
df.reindex(all_days)

fails with:

...
ValueError: cannot reindex from a duplicate axis

(by this it means the index has duplicates, not that it is itself a dup)

Instead, we can use .loc to look up entries for all dates in range:

df.loc[all_days]

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-17  NaN                    NaN
2016-11-18  "2016-11-18 04:00:00"  d

fillna can be used on the column series to fill blanks if needed.

Create with Resource Method

php artisan make:controller --resource ControllerName  --model=ModelName

Use It With a path

php artisan make:controller --resource path/ControllerName  --model=ModelName

Range("C1:C10").Formula = "=A1+B1"

Simple as that.

It autofills (FillDown) the range with the formula.

to escape non-alphanumeric characters of string variables, including dots, you could use re.escape:

import re

expression = 'whatever.v1.dfc'
escaped_expression = re.escape(expression)
print(escaped_expression)

output:

whatever\.v1\.dfc

you can use the escaped expression to find/match the string literally.

On a mac / in Terminal:

1. Show Inspector (right click within the terminal window or Shell >Show Inspector)
2. click the Settings icon above "running processes"
3. choose from the list of options under "Signal Process Group" (Kill, terminate, interrupt, etc).

DROP TABLE IF EXISTS [table_name]

it first checks if the table exists, if it does it deletes the table while

DROP TABLE [table_name]

it deletes without checking, so if it doesn't exist it exits with an error

This should work:

System.currentTimeMillis();

W3C CSS Transitions Draft

The completion of a CSS Transition generates a corresponding DOM Event. An event is fired for each property that undergoes a transition. This allows a content developer to perform actions that synchronize with the completion of a transition.

Webkit

To determine when a transition completes, set a JavaScript event listener function for the DOM event that is sent at the end of a transition. The event is an instance of WebKitTransitionEvent, and its type is webkitTransitionEnd.

box.addEventListener( 'webkitTransitionEnd', 
    function( event ) { alert( "Finished transition!" ); }, false );

Mozilla

There is a single event that is fired when transitions complete. In Firefox, the event is transitionend, in Opera, oTransitionEnd, and in WebKit it is webkitTransitionEnd.

Opera

There is one type of transition event available. The oTransitionEnd event occurs at the completion of the transition.

Internet Explorer

The transitionend event occurs at the completion of the transition. If the transition is removed before completion, the event will not fire.

Stack Overflow: How do I normalize CSS3 Transition functions across browsers?

You will not write code into a static block that needs to be invoked anywhere in your program. If the purpose of the code is to be invoked then you must place it in a method.

You can write static initializer blocks to initialize static variables when the class is loaded but this code can be more complex..

A static initializer block looks like a method with no name, no arguments, and no return type. Since you never call it it doesn't need a name. The only time its called is when the virtual machine loads the class.

If you are using debug configuration for maven, use the command

clean install

And skip all the tests.

try this

use mydatabase
create procedure sp_onetwothree as
select 1 as '1', 2 as '2', 3 as '3'
go
SELECT a.[1], a.[2]
FROM OPENROWSET('SQLOLEDB','myserver';'sa';'mysapass',
    'exec mydatabase.dbo.sp_onetwothree') AS a
GO

If using MS Access (especially older versions like 2003) you are forced to use TEXT datatype on SQL Server as MS Access does not recognize nvarchar(MAX) as a Memo field in Access, whereas TEXT is recognized as a Memo-field.

Likely you will not only need to split into train and test, but also cross validation to make sure your model generalizes. Here I am assuming 70% training data, 20% validation and 10% holdout/test data.

Check out the np.split:

If indices_or_sections is a 1-D array of sorted integers, the entries indicate where along axis the array is split. For example, [2, 3] would, for axis=0, result in

ary[:2] ary[2:3] ary[3:]

t, v, h = np.split(df.sample(frac=1, random_state=1), [int(0.7*len(df)), int(0.9*len(df))]) 

For someone looking to solve same by using maven. Add below dependency in POM:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>7.0.0.jre8</version>
</dependency>

And use below code for connection:

String connectionUrl = "jdbc:sqlserver://localhost:1433;databaseName=master;user=sa;password=your_password";

try {
    System.out.print("Connecting to SQL Server ... ");
    try (Connection connection = DriverManager.getConnection(connectionUrl))        {
        System.out.println("Done.");
    }
} catch (Exception e) {
    System.out.println();
    e.printStackTrace();
}

Look for this link for other CRUD type of queries.

well, you can do it a lot of ways... one of them is to create a HttpRequest. I would advise you against calling your own webapi from your own MVC (the idea is redundant...) but, here's a end to end tutorial.

Depending on the type of your variable, one of abs(int), labs(long), llabs(long long), imaxabs(intmax_t), fabsf(float), fabs(double), or fabsl(long double).

Those functions are all part of the C standard library, and so are present both in Objective-C and plain C (and are generally available in C++ programs too.)

(Alas, there is no habs(short) function. Or scabs(signed char) for that matter...)

Apple's and GNU's Objective-C headers also include an ABS() macro which is type-agnostic. I don't recommend using ABS() however as it is not guaranteed to be side-effect-safe. For instance, ABS(a++) will have an undefined result.

If you're using C++ or Objective-C++, you can bring in the <cmath> header and use std::abs(), which is templated for all the standard integer and floating-point types.

try this:

key=key.replace(/ /g,"_");

that'll do a global find/replace

javascript replace

put your jquery function inside ready function for call click event:

$(document).ready(function() {

  $("#ancherComplaint").click(function () {
     alert($(this).attr("id"));
  });

});

I have several projects in a solution. For some of the projects, I previously added the references manually. When I used NuGet to update the WebAPI package, those references were not updated automatically.

I found out that I can either manually update those reference so they point to the v5 DLL inside the Packages folder of my solution or do the following.

1. Go to the "Manage NuGet Packages"
2. Select the Installed Package "Microsoft ASP.NET Web API 2.1"
3. Click Manage and check the projects that I manually added before.

you can also use

word-break: break-all;

when nothing seems working this works always ;)

The easiest solution:

CREATE USER dev WITH PASSWORD 'dev';
CREATE DATABASE test_development;
GRANT ALL PRIVILEGES ON DATABASE test_development to dev;
ALTER ROLE dev CREATEROLE CREATEDB;

In the Laravel root folder chmod the storage directory to 777

It's really quite easy.

if (number == 0) return 0;
if (number == 1) return 0;
if (number == 2) return 0;
if (number == 3) return 1;
if (number == 4) return 1;
if (number == 5) return 1;
if (number == 6) return 2;

(I have of course omitted some of the program for the sake of brevity.) If the programmer gets tired of typing this all out, I'm sure that he or she could write a separate program to generate it for him. I happen to be aware of a certain operator, /, that would simplify his job immensely.

The registry path for official images (without a slash in the name) is library/<image>. Try this instead:

docker pull registry.hub.docker.com/library/busybox

append() & prepend() are for inserting content inside an element (making the content its child) while after() & before() insert content outside an element (making the content its sibling).

In python version >= 2.7 and in python 3:

d = {el:0 for el in a}

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:

RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);

There, &rect is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.

The code should create a dynamic variable:

RectInvoice *rect =  new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);

There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.

To return a resolved promise, you can use:

return $q.defer().resolve();

If you need to resolve something or return data:

return $q.defer().resolve(function(){

    var data;
    return data;

});

If you're not worried about a couple minutes time to do so, a solution would be to rm -rf node_modules and npm install again to rebuild the local modules.

select regexp_replace(field, E'[\\n\\r\\u2028]+', ' ', 'g' )

I had the same problem in my postgres d/b, but the newline in question wasn't the traditional ascii CRLF, it was a unicode line separator, character U2028. The above code snippet will capture that unicode variation as well.

Update... although I've only ever encountered the aforementioned characters "in the wild", to follow lmichelbacher's advice to translate even more unicode newline-like characters, use this:

select regexp_replace(field, E'[\\n\\r\\f\\u000B\\u0085\\u2028\\u2029]+', ' ', 'g' )

You can't have duplicated keys in a dictionary. Use a dict of lists:

for line in data_list:
  regNumber = line[0]
  name = line[1]
  phoneExtn = line[2]
  carpark = line[3].strip()
  details = (name,phoneExtn,carpark)
  if not data_dict.has_key(regNumber):
    data_dict[regNumber] = [details]
  else:
    data_dict[regNumber].append(details)

The reason you get a ConcurrentModificationException is because an entry is removed via Set.remove() as opposed to Iterator.remove(). If an entry is removed via Set.remove() while an iteration is being done, you will get a ConcurrentModificationException. On the other hand, removal of entries via Iterator.remove() while iteration is supported in this case.

The new for loop is nice, but unfortunately it does not work in this case, because you can't use the Iterator reference.

If you need to remove an entry while iteration, you need to use the long form that uses the Iterator directly.

for (Iterator<Integer> it = set.iterator(); it.hasNext();) {
    Integer element = it.next();
    if (element % 2 == 0) {
        it.remove();
    }
}

Clearly you aren't sending the data with ObjectOutputStream: you are just writing the bytes.

• If you read with readObject() you must write with writeObject().
• If you read with readUTF() you must write with writeUTF().
• If you read with readXXX() you must write with writeXXX(), for most values of XXX.

This isn't an answer. I just want to show that IF NOT EXISTS(...) INSERT method isn't safe. You have to execute first Session #1 and then Session #2. After v #2 you will see that without an UNIQUE index you could get duplicate pairs (SoftwareName,SoftwareSystemType). Delay from session #1 is used to give you enough time to execute the second script (session #2). You could reduce this delay.

In Visual Studio, you can't just open a .cpp file and expect it to run. You must create a project first, or open the .cpp in some existing project.

In your case, there is no project, so there is no project to build.

Go to File --> New --> Project --> Visual C++ --> Win32 Console Application. You can uncheck "create a directory for solution". On the next page, be sure to check "Empty project".

Then, You can add .cpp files you created outside the Visual Studio by right clicking in the Solution explorer on folder icon "Source" and Add->Existing Item.

Obviously You can create new .cpp this way too (Add --> New). The .cpp file will be created in your project directory.

Then you can press ctrl+F5 to compile without debugging and can see output on console window.

If you're talking about last time the table was updated in terms of its structured has changed (new column added, column changed etc.) - use this query:

SELECT name, [modify_date] FROM sys.tables

If you're talking about DML operations (insert, update, delete), then you either need to persist what that DMV gives you on a regular basis, or you need to create triggers on all tables to record that "last modified" date - or check out features like Change Data Capture in SQL Server 2008 and newer.

I had problems with the other suggestions because I want to sometimes return values from my methods. If you try to use MethodInvoker with return values it doesn't seem to like it. So the solution I use is like this (very happy to hear a way to make this more succinct - I'm using c#.net 2.0):

    // Create delegates for the different return types needed.
    private delegate void VoidDelegate();
    private delegate Boolean ReturnBooleanDelegate();
    private delegate Hashtable ReturnHashtableDelegate();

    // Now use the delegates and the delegate() keyword to create 
    // an anonymous method as required

    // Here a case where there's no value returned:
    public void SetTitle(string title)
    {
        myWindow.Invoke(new VoidDelegate(delegate()
        {
            myWindow.Text = title;
        }));
    }

    // Here's an example of a value being returned
    public Hashtable CurrentlyLoadedDocs()
    {
        return (Hashtable)myWindow.Invoke(new ReturnHashtableDelegate(delegate()
        {
            return myWindow.CurrentlyLoadedDocs;
        }));
    }

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

Further the previous answers about Dropbox, I implemented the following files tree such as only the PLIST file has to be uploaded to Dropbox:

1. upload the ipa file to your server in http (no change here)
2. upload the provisioning (.mobileprovision) file to your server in http (no change here)
3. upload the plist file to your dropbox (no change to do inside the plist file as the URLs are in absolute)

4. use the option "Share the link with Dropbox" which copies the link to your clipboard. This link has to be copied into your html file into the itms-servivces URL's query after changing the part www.dropbox.com by dl.dropboxusercontent.com. Note I URL encoded the link as suggested by @Mike but I don't test without to do it. Now the itms-services URL's query should look like this: itms-services://?action=download-manifest&url=https%3A%2F%2Fdl.dropboxusercontent.com%2Fs%2FYourShortDropboxLink.plist

5. upload the html file to your server in http. Note the html file contains both links to ipa and provisioning files.

6. access to your html file from your device and now the ipa can be installed by OTA like usually.

From now, only the ipa file has to be changed to provide next app versions by OTA to your beta testers. Until Apple is yet changing the security rules.

I join here after the very simple HTML file I'm using:

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

There is no way to get the memory address of a value in Python 2.7 in general. In Jython or PyPy, the implementation doesn't even know your value's address (and there's not even a guarantee that it will stay in the same place—e.g., the garbage collector is allowed to move it around if it wants).

However, if you only care about CPython, id is already returning the address. If the only issue is how to format that integer in a certain way… it's the same as formatting any integer:

>>> hex(33)
0x21
>>> '{:#010x}'.format(33) # 32-bit
0x00000021
>>> '{:#018x}'.format(33) # 64-bit
0x0000000000000021

… and so on.

However, there's almost never a good reason for this. If you actually need the address of an object, it's presumably to pass it to ctypes or similar, in which case you should use ctypes.addressof or similar.

You need a bindingsource object to act as an intermediary and assist in the binding. Then instead of updating the user interface, update the underlining model.

var model = (Fruit) bindingSource1.DataSource;

model.FruitType = "oranges";

bindingSource.ResetBindings();

Read up on BindingSource and simple data binding for Windows Forms.

The 3rd option is to create a "Policy" table, then a "SectionsMain" table that stores all of the fields that are in common across the types of sections. Then create other tables for each type of section that only contain the fields that are not in common.

Deciding which is best depends mostly on how many fields you have and how you want to write your SQL. They would all work. If you have just a few fields then I would probably go with #1. With "lots" of fields I would lean towards #2 or #3.

Are you referring to address validation? Like the previous answer by Mike, you need to cater for the othe 95%.

What you can do is when the user select's their country, then enable validation. Address validation and zipcode validation are 2 different things. Validating the ZIP is just making sure its integer. Address validation is validating the actual address for accuracy, preferably for mailing.

Don't enter the password with command. Just enter,

mysqldump -u <username> -p <db_name> > <backup_file>.sql

Then you will get a prompt to enter password.

Every Set has an iterator(). A normal HashSet's iterator is quite random, a TreeSet does it by sort order, a LinkedHashSet iterator iterates by insert order.

You can't replace an element in a LinkedHashSet, however. You can remove one and add another, but the new element will not be in the place of the original. In a LinkedHashMap, you can replace a value for an existing key, and then the values will still be in the original order.

Also, you can't insert at a certain position.

Maybe you'd better use an ArrayList with an explicit check to avoid inserting duplicates.

My solution:

#!/bin/bash
user_cmds="$@"

GID=$(id -g $USER)
UID=$(id -u $USER)
RUN_SCRIPT=$(mktemp -p $(pwd))
(
cat << EOF
addgroup --gid $GID $USER
useradd --no-create-home --home /cmd --gid $GID --uid $UID  $USER
cd /cmd
runuser -l $USER -c "${user_cmds}"
EOF
) > $RUN_SCRIPT

trap "rm -rf $RUN_SCRIPT" EXIT

docker run -v $(pwd):/cmd --rm my-docker-image "bash /cmd/$(basename ${RUN_SCRIPT})"

This allows the user to run arbitrary commands using the tools provides by my-docker-image. Note how the user's current working directory is volume mounted to /cmd inside the container.

I am using this workflow to allow my dev-team to cross-compile C/C++ code for the arm64 target, whose bsp I maintain (the my-docker-image contains the cross-compiler, sysroot, make, cmake, etc). With this a user can simply do something like:

cd /path/to/target_software
cross_compile.sh "mkdir build; cd build; cmake ../; make"

Where cross_compile.sh is the script shown above. The addgroup/useradd machinery allows user-ownership of any files/directories created by the build.

While this works for us. It seems sort of hacky. I'm open to alternative implementations ...

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.
