Programs & Examples On #Longtable

Two utilities in package taRifx can be used in concert to produce multi-row tables of nested heirarchies.

library(datasets)
library(taRifx)
library(xtable)

test.by <- bytable(ChickWeight$weight, list( ChickWeight$Chick, ChickWeight$Diet) )
colnames(test.by) <- c('Diet','Chick','Mean Weight')
print(latex.table.by(test.by), include.rownames = FALSE, include.colnames = TRUE, sanitize.text.function = force)
#   then add \usepackage{multirow} to the preamble of your LaTeX document
#   for longtable support, add ,tabular.environment='longtable' to the print command (plus add in ,floating=FALSE), then \usepackage{longtable} to the LaTeX preamble

This is the thing, it is more a matter of content than it is a time issue. The TCP protocol requires that a packet that was not delivered must be check, verified and redelivered. UDP does not use this requirement. So if you sent a file which contains millions of packets using UDP, like a video, if some of the packets are missing upon delivery, they will most likely go unmissed.

for me, i did this and it worked. just go to C:\Users\$your username$\AppData(which is hidden most likely)\Local\ then at this location try to find this Folder : "Android" if you don't have it already make one with the exact name and try to open the android studio again.

add the line to your .bashrc or .profile. The variables set in $HOME/.profile are active for the current user, the ones in /etc/profile are global. The .bashrc is pulled on each bash session start.

you can use this extension method and call it like this.

DataTable dt =   YourList.ToDataTable();

public static DataTable ToDataTable<T>(this List<T> iList)
        {
            DataTable dataTable = new DataTable();
            PropertyDescriptorCollection propertyDescriptorCollection =
                TypeDescriptor.GetProperties(typeof(T));
            for (int i = 0; i < propertyDescriptorCollection.Count; i++)
            {
                PropertyDescriptor propertyDescriptor = propertyDescriptorCollection[i];
                Type type = propertyDescriptor.PropertyType;

                if (type.IsGenericType && type.GetGenericTypeDefinition() == typeof(Nullable<>))
                    type = Nullable.GetUnderlyingType(type);


                dataTable.Columns.Add(propertyDescriptor.Name, type);
            }
            object[] values = new object[propertyDescriptorCollection.Count];
            foreach (T iListItem in iList)
            {
                for (int i = 0; i < values.Length; i++)
                {
                    values[i] = propertyDescriptorCollection[i].GetValue(iListItem);
                }
                dataTable.Rows.Add(values);
            }
            return dataTable;
        }

This should display 'Tue':

new SimpleDateFormat("EEE").format(new Date());

This should display 'Tuesday':

new SimpleDateFormat("EEEE").format(new Date());

This should display 'T':

new SimpleDateFormat("EEEEE").format(new Date());

So your specific example would be:

new SimpleDateFormat("yyyy-MM-EEE").format(new Date());

If you care only about reading, somewhat faster (but might read stale data) version is to read from multiple connections from multiple threads (connection per-thread).

First find the items, in the table:

SELECT COUNT(*) FROM table

then read in pages (LIMIT/OFFSET):

SELECT * FROM table ORDER BY _ROWID_ LIMIT <limit> OFFSET <offset>

where and are calculated per-thread, like this:

int limit = (count + n_threads - 1)/n_threads;

for each thread:

int offset = thread_index * limit

For our small (200mb) db this made 50-75% speed-up (3.8.0.2 64-bit on Windows 7). Our tables are heavily non-normalized (1000-1500 columns, roughly 100,000 or more rows).

Too many or too little threads won't do it, you need to benchmark and profile yourself.

Also for us, SHAREDCACHE made the performance slower, so I manually put PRIVATECACHE (cause it was enabled globally for us)

If above all options are not working and you have used nuget packages like Microsoft.Net.Compilers and CodeDom and still not working then there is issue with your project file open project file. Project file is using one of the compiler option which not support your selected language. Open project file with notepad++ and remove the following line.

Answer given by @mpm is not working it gives the error

Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater: {0}, Duplicate key: {1}

To avoid this along with

ng-repeat="t in getTimes(4)"

use

track by $index

like this

<div ng-repeat="t in getTimes(4) track by $index">TEXT</div>

In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.

Example: Any code that uses worksheet events like Worksheet_SelectionChange or Worksheet_Calculate.

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

You can configure your pod with a grace period (for example 30 seconds or more, depending on container startup time and image size) and set "imagePullPolicy: "Always". And use kubectl delete pod pod_name. A new container will be created and the latest image automatically downloaded, then the old container terminated.

Example:

spec:
  terminationGracePeriodSeconds: 30
  containers:
  - name: my_container
    image: my_image:latest
    imagePullPolicy: "Always"

I'm currently using Jenkins for automated builds and image tagging and it looks something like this:

kubectl --user="kube-user" --server="https://kubemaster.example.com"  --token=$ACCESS_TOKEN set image deployment/my-deployment mycontainer=myimage:"$BUILD_NUMBER-$SHORT_GIT_COMMIT"

Another trick is to intially run:

kubectl set image deployment/my-deployment mycontainer=myimage:latest

and then:

kubectl set image deployment/my-deployment mycontainer=myimage

It will actually be triggering the rolling-update but be sure you have also imagePullPolicy: "Always" set.

Update:

another trick I found, where you don't have to change the image name, is to change the value of a field that will trigger a rolling update, like terminationGracePeriodSeconds. You can do this using kubectl edit deployment your_deployment or kubectl apply -f your_deployment.yaml or using a patch like this:

kubectl patch deployment your_deployment -p \
  '{"spec":{"template":{"spec":{"terminationGracePeriodSeconds":31}}}}'

Just make sure you always change the number value.

Other answers have explained what 'detached HEAD' means. I try to answer why I want to do that. There are some cases I prefer checkout a commit than checkout a temporary branch.

1. To compile/build at some specific commit (maybe for your daily build or just to release some specific version to test team), I used to checkout a tmp branch for that, but then I need to remember to delete the tmp branch after build. So I found checkout a commit is more convenient, after the build I just checkout to the original branch.

2. To check what codes look like at that commit, maybe to debug an issue. The case is not much different from my case #1, I can also checkout a tmp branch for that but then I need to remember delete it. So I choose to checkout a commit more often.

3. This is probably just me being paranoid, so I prepare to merge another branch but I already suspect I would get some merge conflict and I want to see them first before merge. So I checkout the head commit then do the merge, see the merge result. Then I git checkout -f to switch back to my branch, using -f to discard any merge conflict. Again I found it more convenient than checkout a tmp branch.

I agree with Bryan's answer

if I do

cell.isUserInteractionEnabled = false 

then the subviews within the cell won't be user interacted.

On the other site, setting

cell.selectionStyle = .none

will trigger the didSelect method despite not updating the selection color.

Using willSelectRowAt is the way I solved my problem. Example:

func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {

    if indexPath.section == 0{

        if indexPath.row == 0{
            return nil
        }

    }
    else if indexPath.section == 1{

        if indexPath.row == 0{
            return nil
        }

    }

    return indexPath

}

get matched string back or false

function preg_match (regex, str) {
  if (new RegExp(regex).test(str)){
    return regex.exec(str);
  }
  return false;
}

You may consider declaring the variables with moudule level scope. Module-level variable is available to all of the procedures in that module, but it is not available to procedures in other modules

For details on Scope of variables refer this link

Please copy the below code into any module, save the workbook and then run the code.

Here is what code does

• The sample subroutine sets the folder path & later the file path. Kindly set them accordingly before you run the code.

• I have added a function IsWorkBookOpen to check if workbook is already then set the workbook variable the workbook name else open the workbook which will be assigned to workbook variable accordingly.

Dim wbA As Workbook
Dim wbB As Workbook

Sub MySubRoutine()
    Dim folderPath As String, fileNm1 As String, fileNm2 As String, filePath1 As String, filePath2 As String

    folderPath = ThisWorkbook.Path & "\"
    fileNm1 = "file1.xlsx"
    fileNm2 = "file2.xlsx"

    filePath1 = folderPath & fileNm1
    filePath2 = folderPath & fileNm2

    If IsWorkBookOpen(filePath1) Then
        Set wbA = Workbooks(fileNm1)
    Else
        Set wbA = Workbooks.Open(filePath1)
    End If


    If IsWorkBookOpen(filePath2) Then
        Set wbB = Workbooks.Open(fileNm2)
    Else
        Set wbB = Workbooks.Open(filePath2)
    End If


    ' your code here
End Sub

Function IsWorkBookOpen(FileName As String)
    Dim ff As Long, ErrNo As Long

    On Error Resume Next
    ff = FreeFile()
    Open FileName For Input Lock Read As #ff
    Close ff
    ErrNo = Err
    On Error GoTo 0

    Select Case ErrNo
    Case 0: IsWorkBookOpen = False
    Case 70: IsWorkBookOpen = True
    Case Else: Error ErrNo
    End Select
End Function

Using Prompt to select the file use below code.

Dim wbA As Workbook
Dim wbB As Workbook

Sub MySubRoutine()
    Dim folderPath As String, fileNm1 As String, fileNm2 As String, filePath1 As String, filePath2 As String

    Dim filePath As String
    cmdBrowse_Click filePath, 1

    filePath1 = filePath

    'reset the variable
    filePath = vbNullString

    cmdBrowse_Click filePath, 2
    filePath2 = filePath

   fileNm1 = GetFileName(filePath1, "\")
   fileNm2 = GetFileName(filePath2, "\")

    If IsWorkBookOpen(filePath1) Then
        Set wbA = Workbooks(fileNm1)
    Else
        Set wbA = Workbooks.Open(filePath1)
    End If


    If IsWorkBookOpen(filePath2) Then
        Set wbB = Workbooks.Open(fileNm2)
    Else
        Set wbB = Workbooks.Open(filePath2)
    End If


    ' your code here
End Sub

Function IsWorkBookOpen(FileName As String)
    Dim ff As Long, ErrNo As Long

    On Error Resume Next
    ff = FreeFile()
    Open FileName For Input Lock Read As #ff
    Close ff
    ErrNo = Err
    On Error GoTo 0

    Select Case ErrNo
    Case 0: IsWorkBookOpen = False
    Case 70: IsWorkBookOpen = True
    Case Else: Error ErrNo
    End Select
End Function

Private Sub cmdBrowse_Click(ByRef filePath As String, num As Integer)

    Dim fd As FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Select workbook " & num
    fd.InitialView = msoFileDialogViewSmallIcons

    Dim FileChosen As Integer

    FileChosen = fd.Show

    fd.Filters.Clear
    fd.Filters.Add "Excel macros", "*.xlsx"


    fd.FilterIndex = 1



    If FileChosen <> -1 Then
        MsgBox "You chose cancel"
        filePath = ""
    Else
        filePath = fd.SelectedItems(1)
    End If

End Sub

Function GetFileName(fullName As String, pathSeparator As String) As String

    Dim i As Integer
    Dim iFNLenght As Integer
    iFNLenght = Len(fullName)

    For i = iFNLenght To 1 Step -1
        If Mid(fullName, i, 1) = pathSeparator Then Exit For
    Next

    GetFileName = Right(fullName, iFNLenght - i)

End Function

If str is null, undefined or 0, this code will set it to "hai"

function(nodeBox, str) {
  str = str || "hai";
.
.
.

If you also need to pass 0, you can use:

function(nodeBox, str) {
  if (typeof str === "undefined" || str === null) { 
    str = "hai"; 
  }
.
.
.

=INDEX(GoogleFinance("CURRENCY:" & "EUR" & "USD", "price", A2), 2, 2)

where A2 is the cell with a date formatted as date.

Replace "EUR" and "USD" with your currency pair.

just set the width of the td/column you want to be fixed and the rest will expand.

<td width="200"></td>

Let's Say If you want to go from ViewController A --> B then

1. Make sure your ViewControllerA is embedded in Navigation Controller

2. In ViewControllerA's Button click you should have code like this.

@IBAction func goToViewController(_ sender: Any) {

    if let viewControllerB = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "ViewControllerB") as? ViewControllerB {

        if let navigator = navigationController {
            navigator.pushViewController(viewControllerB, animated: true)
        }
    }
}

3. Please double check your storyboard name, and ViewControllerB's Identifier mentioned in storyboard for ViewControllerB's View

Look at StoryboardID = ViewControllerB

An alternative to the answer provided by @Marc

SELECT SUBSTRING(LEFT(YOUR_FIELD, CHARINDEX('[', YOUR_FIELD) - 1), CHARINDEX(';', YOUR_FIELD) + 1, 100)
FROM YOUR_TABLE
WHERE CHARINDEX('[', YOUR_FIELD) > 0 AND
    CHARINDEX(';', YOUR_FIELD) > 0;

This makes sure the delimiters exist, and solves an issue with the currently accepted answer where doing the LEFT last is working with the position of the last delimiter in the original string, rather than the revised substring.

I Got AutoFlash light with below simple Three Steps.

• I just added Camera and Flash Permission in Manifest.xml file

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />

<uses-permission android:name="android.permission.FLASHLIGHT"/>
<uses-feature android:name="android.hardware.camera.flash" android:required="false" />

• In your Camera Code do this way.

  //Open Camera
  Camera  mCamera = Camera.open(); 
  
  //Get Camera Params for customisation
  Camera.Parameters parameters = mCamera.getParameters();
  
  //Check Whether device supports AutoFlash, If you YES then set AutoFlash
  List<String> flashModes = parameters.getSupportedFlashModes();
  if (flashModes.contains(android.hardware.Camera.Parameters.FLASH_MODE_AUTO))
  {
       parameters.setFlashMode(Parameters.FLASH_MODE_AUTO);
  }
  mCamera.setParameters(parameters);
  mCamera.startPreview();
  

• Build + Run —> Now Go to Dim light area and Snap photo, you should get auto flash light if device supports.

You might add the second snippet as a field definition for ICourseBased in a view.

DECLARE VIEW MyView
AS
  SELECT
  case 
  when FC.CourseId is not null then cast(1 as bit)
  else cast(0 as bit)
  end
  as IsCoursedBased
  ...

SELECT ICourseBased FROM MyView

You can check for a network connection in .NET 2.0 using GetIsNetworkAvailable():

System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable()

To monitor changes in IP address or changes in network availability use the events from the NetworkChange class:

System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged
System.Net.NetworkInformation.NetworkChange.NetworkAddressChanged

require 'json'

hash = JSON.parse string

work with the hash and do what you want to do.

At the risk of irritating you;

You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.

Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.

What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.

It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.

In short, it's just unnecessarily conflating the matter when there is no need to.

Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().

Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)

Here is a function that will allow you to remove all localStorage items with exceptions. You will need jQuery for this function. You can download the gist.

You can call it like this

let clearStorageExcept = function(exceptions) {
  let keys = [];
  exceptions = [].concat(exceptions); // prevent undefined

  // get storage keys
  $.each(localStorage, (key) => {
    keys.push(key);
  });

  // loop through keys
  for (let i = 0; i < keys.length; i++) {
    let key = keys[i];
    let deleteItem = true;

    // check if key excluded
    for (let j = 0; j < exceptions.length; j++) {
      let exception = exceptions[j];
      if (key == exception) {
        deleteItem = false;
      }
    }

    // delete key
    if (deleteItem) {
      localStorage.removeItem(key);
    }
  }
};

You need to escape the ampersand:

<div class="test">&amp;times</div>

&times means a multiplication sign. (Technically it should be × but lenient browsers let you omit the ;.)

If you have lodash you can use its .get method

_.get(a, 'b.c.d.e')

or give it a default value

_.get(a, 'b.c.d.e', default)

The ParameterizedThreadStart takes one parameter. You can use that to send one parameter, or a custom class containing several properties.

Another method is to put the method that you want to start as an instance member in a class along with properties for the parameters that you want to set. Create an instance of the class, set the properties and start the thread specifying the instance and the method, and the method can access the properties.

No this will be a problem. PHP Variable Functions

If you have downloaded sdk manager zip (from https://developer.android.com/studio/#downloads), then you have Android SDK Location as root of the extracted folder.

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

You are confusing objects and collections of objects. Specifically, you are confusing binary flags with sets of binary flags. A proper solution would look like this:

// These are individual flags
enum AnimalFlag // Flag, not Flags
{
    HasClaws = 0,
    CanFly,
    EatsFish,
    Endangered
};

class AnimalFlagSet
{
    int m_Flags;

  public:

    AnimalFlagSet() : m_Flags(0) { }

    void Set( AnimalFlag flag ) { m_Flags |= (1 << flag); }

    void Clear( AnimalFlag flag ) { m_Flags &= ~ (1 << flag); }

    bool Get( AnimalFlag flag ) const { return (m_Flags >> flag) & 1; }

};

I use this code

                string PZipPath = @"C:\Program Files\7-Zip\7z.exe";
                string sourceCompressDir = @"C:\Test";
                string targetCompressName = @"C:\Test\abc.zip";
                string CompressName = targetCompressName.Split('\\').Last();
                string[] fileCompressList = Directory.GetFiles(sourceCompressDir, "*.*");

                    if (fileCompressList.Length == 0)
                    {
                        MessageBox.Show("No file in directory", "Important Message");
                        return;
                    }
                    string filetozip = null;
                    foreach (string filename in fileCompressList)
                    {
                        filetozip = filetozip + "\"" + filename + " ";
                    }

                    ProcessStartInfo pCompress = new ProcessStartInfo();
                    pCompress.FileName = PZipPath;
                    if (chkRequestPWD.Checked == true)
                    {
                        pCompress.Arguments = "a -tzip \"" + targetCompressName + "\" " + filetozip + " -mx=9" + " -p" + tbPassword.Text;
                    }
                    else
                    {
                        pCompress.Arguments = "a -tzip \"" + targetCompressName + "\" \"" + filetozip + "\" -mx=9";
                    }

You should use labels attribute inside plot function and the value of this attribute should be the vector containing the values that you want for each point to have.

Yeah, I'm using tf 2.0-beta and want to enable/disable the default logging. The environment variable and methods in tf1.X don't seem to exist anymore.

I stepped around in PDB and found this to work:

# close the TF2 logger
tf2logger = tf.get_logger()
tf2logger.error('Close TF2 logger handlers')
tf2logger.root.removeHandler(tf2logger.root.handlers[0])

I then add my own logger API (in this case file-based)

logtf = logging.getLogger('DST')
logtf.setLevel(logging.DEBUG)

# file handler
logfile='/tmp/tf_s.log'
fh = logging.FileHandler(logfile)
fh.setFormatter( logging.Formatter('fh %(asctime)s %(name)s %(filename)s:%(lineno)d :%(message)s') )
logtf.addHandler(fh)
logtf.info('writing to %s', logfile)

The split of kotlin-stdlib into kotlin-stdlib-jre7 and kotlin-stdlib-jre8 was only introduced with Kotlin 1.1, that's why the dependency cannot be resolved, the package version simply does not exist.

It looks like the update to your project files failed at some point and set the Kotlin version to 1.0.7. If this is a new project and there's nothing holding you back from using 1.1.1, I'd switch to that. Your problem should be gone after doing this.

I had the same issue. after adding below code to my app.js file it fixed.

var cors = require('cors')
app.use(cors());

shell_exec - Execute command via shell and return the complete output as a string

exec - Execute an external program.

The difference is that with shell_exec you get output as a return value.

The major difference is time-out, WCF Service has timed-out when there is no response, but web-service does not have this property.

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

You have to select the device in the schemes menu in the top left where you used to select between simulator/device. It won’t let you archive a build for the simulator.

Or you may find that if the iOS device is already selected the archive box isn’t selected when you choose “Edit Schemes” => “Build”.

It seems despite the intrinsic limitations of the money datatype, if you're already using it (or have inherited it as I have) the answer to your question is, use DECIMAL.

I found the information found at http://help.infragistics.com/Help/NetAdvantage/jQuery/2013.1/CLR4.0/html/igOlapXmlaDataSource_Configuring_IIS_for_Cross_Domain_OLAP_Data.html to be very helpful in setting up HTTP OPTIONS for a WCF service in IIS 7.

I added the following to my web.config and then moved the OPTIONSVerbHandler in the IIS 7 'hander mappings' list to the top of the list. I also gave the OPTIONSVerbHander read access by double clicking the hander in the handler mappings section then on 'Request Restrictions' and then clicking on the access tab.

Unfortunately I quickly found that IE doesn't seem to support adding headers to their XDomainRequest object (setting the Content-Type to text/xml and adding a SOAPAction header).

Just wanted to share this as I spent the better part of a day looking for how to handle it.

Java's Double class has members containing the Min and Max value for the type.

2^-1074 <= x <= (2-2^-52)·2^1023 // where x is the double.

Check out the Min_VALUE and MAX_VALUE static final members of Double.

(some)People will suggest against using floating point types for things where accuracy and precision are critical because rounding errors can throw off calculations by measurable (small) amounts.

One possibility is, if you are familiar with PDF format:

1. Create some simply PDF with one page (Page should be contained within one object)
2. Copy object multiply times
3. Add references to the copied objects to the page catalog
4. Fix xref table

You get an valid document of any size, entire file will be processed by a reader.

If you’re familiar with the browsers locaStorage object, you know that there’s no provision for providing an expiry time. However, we can use Javascript to add a TTL (Time to live) to invalidate items in locaStorage after a certain period of time elapses.

function setLocalStorageItem(key, value, ttl) {
    // `item` is an object which contains the original value
    // as well as the time when it's supposed to expire
    let item = {
        value: value,
        expiry: ttl ? Date.now() + ttl : null
    };

    localStorage.setItem(key, JSON.stringify(item));
}

function getLocalStorageItem(key) {
    let item = localStorage.getItem(key);
    
    // if the item doesn't exist, return null
    if (!item) return null;

    item = JSON.parse(item);
    // compare the expiry time of the item with the current time
    if (item.expiry && Date.now() > item.expiry) {
        // If the item is expired, delete the item from storage and return null
        localStorage.removeItem(key);

        return null;
    }
    
    return item.value;
}

List<String> sids = new ArrayList<String>();
List<String> lids = new ArrayList<String>();

String query = "SELECT rlink_id, COUNT(*)"

             + "GROUP BY rlink_id ";

Statement stmt = yourconnection.createStatement();
try {
    ResultSet rs4 = stmt.executeQuery(query);

    while (rs4.next()) {
        sids.add(rs4.getString(1));
        lids.add(rs4.getString(2));
    }
} finally {
    stmt.close();
}

String show[] = sids.toArray(sids.size());
String actuate[] = lids.toArray(lids.size());

Additional information for modern (systemd) linux systems.

There are many resources about this of values that may need tweaking (such as How to increase maximum number of JVM threads (Linux 64bit)); however a new limit is imposed by way of the systemd "TasksMax" limit which sets pids.max on the cgroup.

For login sessions the UserTasksMax default is 33% of the kernel limit pids_max (usually 12,288) and can be override in /etc/systemd/logind.conf.

For services the DefaultTasksMax default is 15% of the kernel limit pids_max (usually 4,915). You can override it for the service by setting TasksMax in "systemctl edit" or update DefaultTasksMax in /etc/systemd/system.conf

I had the same issue. I found that ipython must be running for jupyter notebook to execute. Do the following:

• Go to the folder where you have your ipython notebook(.ipynb)
• Press shift and right click on the empty space then select "open command window here". This will open a command prompt window.
• Type ipython. This will start ipython.
• Open another command prompt window and open jupyter notebook.
• Open your file again and go to cell>>>run cell.

This should work. It worked for me. Cheers!

Another possibility is to use the options with data attributes, like this(minimum date 1 week before):

<input class='datepicker' data-date-start-date="-1w">

More info: http://bootstrap-datepicker.readthedocs.io/en/latest/options.html

If you just want to run some code when an element becomes visible in the viewport:

function onVisible(element, callback) {
  new IntersectionObserver((entries, observer) => {
    entries.forEach(entry => {
      if(entry.intersectionRatio > 0) {
        callback(element);
        observer.disconnect();
      }
    });
  }).observe(element);
}

When the element has become visible the intersection observer calls callback and then destroys itself with .disconnect().

Use it like this:

onVisible(document.querySelector("#myElement"), () => console.log("it's visible"));

After searching through many solutions I decided to blog about how to sort in jquery. In summary, steps to sort jquery "array-like" objects by data attribute...

1. select all object via jquery selector
2. convert to actual array (not array-like jquery object)
3. sort the array of objects
4. convert back to jquery object with the array of dom objects

Html

<div class="item" data-order="2">2</div>
<div class="item" data-order="1">1</div>
<div class="item" data-order="4">4</div>
<div class="item" data-order="3">3</div>

Plain jquery selector

$('.item');

[<div class="item" data-order="2">2</div>,
 <div class="item" data-order="1">1</div>,
 <div class="item" data-order="4">4</div>,
 <div class="item" data-order="3">3</div>
]

Lets sort this by data-order

function getSorted(selector, attrName) {
    return $($(selector).toArray().sort(function(a, b){
        var aVal = parseInt(a.getAttribute(attrName)),
            bVal = parseInt(b.getAttribute(attrName));
        return aVal - bVal;
    }));
}

> getSorted('.item', 'data-order')

[<div class="item" data-order="1">1</div>,
 <div class="item" data-order="2">2</div>,
 <div class="item" data-order="3">3</div>,
 <div class="item" data-order="4">4</div>
]

See how getSorted() works.

Hope this helps!

Here's a bash script to check the maximum limit of a remote server (uses curl and perl).

You just need some kind of an url that can be extended with 'x' and always return 200 (or adapt it to your needs). At some point it will break and the script will display the max length.

Here's the code:

url='http://someurl/someendpoint?var1=blah&token='
ok=0
times=1

while :; do
    length=$((times+${#url}))
    echo trying with $length
    token=$(perl -le 'print "x"x'$times)
    result=$(curl -sLw '%{http_code}' -o /dev/null "${url}${token}")

    if [[ $result == 200 ]]; then
        if [[ $ok == $times ]]; then
            echo "max length is $length"
            break
        fi
        ok=$times
        times=$((times+1024))
    else
        times=$(((times+ok)/2))
    fi
done

This solution worked to me:

<summary>Tootsie roll tiramisu macaroon wafer carrot cake. &#xD;Danish topping sugar plum tart bonbon caramels cake.</summary>

You will have the text in two lines.

This worked to me using the XmlReader.Read method.

This simple way worked fine for me:

<ul style="margin-top:-30px;">

Try [^- ], \s will match 5 other characters beside the space (like tab, newline, formfeed, carriage return).

JasonPy - a few things...

if you stick a button in a loop it will be created over and over and over again... which is probably not what you want. (maybe it is)...

The reason it always gets the last index is lambda events run when you click them - not when the program starts. I'm not sure 100% what you are doing but maybe try storing the value when it's made then call it later with the lambda button.

eg: (don't use this code, just an example)

for entry in stuff_that_is_happening:
    value_store[entry] = stuff_that_is_happening

then you can say....

button... command: lambda: value_store[1]

hope this helps!

You can use list comprehensions.

[(k,v) for k,v in a.iteritems()] 

will get you [ ('a', 1), ('b', 2), ('c', 3) ] and

[(v,k) for k,v in a.iteritems()] 

the other example.

Read more about list comprehensions if you like, it's very interesting what you can do with them.

You have to add max-height property.

.ScrollStyle_x000D_
{_x000D_
    max-height: 150px;_x000D_
    overflow-y: scroll;_x000D_
}

<div class="ScrollStyle">_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_
  Scrollbar Test!<br/>_x000D_

You need to wait until the image is loaded before you draw it. Try this instead:

var canvas = document.getElementById('viewport'),
context = canvas.getContext('2d');

make_base();

function make_base()
{
  base_image = new Image();
  base_image.src = 'img/base.png';
  base_image.onload = function(){
    context.drawImage(base_image, 0, 0);
  }
}

i.e. draw the image in the onload callback of the image.

Given your edit i assume you have the class name as a string and want to instantiate the class? Just use a dictionary as a dispatcher.

class Foo(object):
    pass

class Bar(object):
    pass

dispatch_dict = {"Foo": Foo, "Bar": Bar}
dispatch_dict["Foo"]() # returns an instance of Foo

FWIW, this BASH script will take a PEM- or DER-format X.509 certificate or OpenSSL public key file (also PEM format) as the first argument and disgorge an OpenSSH RSA public key. This expands upon @mkalkov's answer above. Requirements are cat, grep, tr, dd, xxd, sed, xargs, file, uuidgen, base64, openssl (1.0+), and of course bash. All except openssl (contains base64) are pretty much guaranteed to be part of the base install on any modern Linux system, except maybe xxd (which Fedora shows in the vim-common package). If anyone wants to clean it up and make it nicer, caveat lector.

# If it is a PEM format X.509 public cert, set $fileType appropriately:

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

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

One think you should change is the call $state.go(). As described here:

• $state.go(to [, toParams] [, options])

The param passed should be the state name

$scope.create = function() {
  // instead of this
  //$state.go("/tab/newpost"); 

  // we should use this
  $state.go("tab.newpost"); 
};

Some cite from doc (the first parameter to of the [$state.go(to \[, toParams\] \[, options\]):

to

String Absolute State Name or Relative State Path

The name of the state that will be transitioned to or a relative state path. If the path starts with ^ or . then it is relative, otherwise it is absolute.

Some examples:

$state.go('contact.detail') will go to the 'contact.detail' state
$state.go('^') will go to a parent state.
$state.go('^.sibling') will go to a sibling state.
$state.go('.child.grandchild') will go to a grandchild state.

To get the entire contents of a file:

$content = [IO.File]::ReadAllText(".\test.txt")

Number of lines:

([IO.File]::ReadAllLines(".\test.txt")).length

or

(gc .\test.ps1).length

Sort of hackish to include trailing empty line:

[io.file]::ReadAllText(".\desktop\git-python\test.ps1").split("`n").count

No, you can't.

But as a solid workaround, I would suggest to classify that first div as position:relative and use div::before to create an underlying element containing your image. Classified as position:absolute you can move it anywhere relative to your initial div.

Don't forget to add content to that new element. Here's some example:

div {
  position: relative;
}    

div::before {
  content: ""; /* empty but necessary */
  position: absolute;
  background: ...
}

Note: if you want it to be 'on top' of the parent div, use div::after instead.

Use '›'

› -> single right angle quote. For single left angle quote, use ‹

As mentioned earlier, you can use the grid system to layout your inputs and labels anyway that you want. The trick is to remember that you can use rows within your columns to break them into twelfths as well.

The example below is one possible way to accomplish your goal and will put the two text boxes near Label3 on the same line when the screen is small or larger.

You can also use the following to set a path where it saves the file.

req.form.uploadDir = "<path>";

Once you have made your choice of the exit command, press enter to finally quit Vim and close the editor (but not the terminal).

Do note that when you press shift + “:” the editor will have the next keystrokes displayed at the bottom left of the terminal. Now if you want to simply quit, write exit or wq (save and exit)

As the error states - the database is not open - it was previously shut down, and someone left it in the middle of the startup process. They may either be intentional, or unintentional (i.e., it was supposed to be open, but failed to do so).

Assuming that's nothing wrong with the database itself, you could open it with a simple statement:(Since the question is asked specifically in the context of SQLPlus, kindly remember to put a statement terminator(Semicolon) at the end mandatorily, otherwise, it will result in an error.)

ALTER DATABASE OPEN;

I would just do

int pnSize = primeNumber.size();
for (int i = 0; i < pnSize; i++)
    cout << primeNumber[i] << ' ';

None of these answers worked for me. This is how I did it.

position: relative;
left: 50%;
-webkit-transform: translateX(-50%);
-ms-transform: translateX(-50%);
transform: translateX(-50%);

I like RDC's response, but why limit the JSON returned to have only arrays at the top level? I needed to allow a dictionary at the top level, so I modified it thus:

extension String
{
    var parseJSONString: AnyObject?
    {
        let data = self.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

        if let jsonData = data
        {
            // Will return an object or nil if JSON decoding fails
            do
            {
                let message = try NSJSONSerialization.JSONObjectWithData(jsonData, options:.MutableContainers)
                if let jsonResult = message as? NSMutableArray {
                    return jsonResult //Will return the json array output
                } else if let jsonResult = message as? NSMutableDictionary {
                    return jsonResult //Will return the json dictionary output
                } else {
                    return nil
                }
            }
            catch let error as NSError
            {
                print("An error occurred: \(error)")
                return nil
            }
        }
        else
        {
            // Lossless conversion of the string was not possible
            return nil
        }
    }

You can use Cell.Interior.Color, I've used it to count the number of cells in a range that have a given background color (ie. matching my legend).

From version 2012 and on you can use

SELECT FORMAT(EmployeeID,'000000')
FROM dbo.RequestItems
WHERE ID=0

I think you misunderstand Unicode and its relationship to Perl. No matter which way you store data, Unicode, ISO-8859-1, or many other things, your program has to know how to interpret the bytes it gets as input (decoding) and how to represent the information it wants to output (encoding). Get that interpretation wrong and you garble the data. There isn't some magic default setup inside your program that's going to tell the stuff outside your program how to act.

You think it's hard, most likely, because you are used to everything being ASCII. Everything you should have been thinking about was simply ignored by the programming language and all of the things it had to interact with. If everything used nothing but UTF-8 and you had no choice, then UTF-8 would be just as easy. But not everything does use UTF-8. For instance, you don't want your input handle to think that it's getting UTF-8 octets unless it actually is, and you don't want your output handles to be UTF-8 if the thing reading from them can't handle UTF-8. Perl has no way to know those things. That's why you are the programmer.

I don't think Unicode in Perl 5 is too complicated. I think it's scary and people avoid it. There's a difference. To that end, I've put Unicode in Learning Perl, 6th Edition, and there's a lot of Unicode stuff in Effective Perl Programming. You have to spend the time to learn and understand Unicode and how it works. You're not going to be able to use it effectively otherwise.

If u want to set background of the list then place the image before the < Textview>

< ImageView
android:background="@drawable/image_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>

and if u want to change color then put color code on above textbox like this

 android:textColor="#ffffff"

open div then put

style="width:100% ; margin:0px auto;" 

image tag (or) content

close div

In the rowdatabound method for 2nd column

GridView gv = (sender as GridView);
gv.HeaderRow.Cells[2].Visible = false;
e.Row.Cells[2].Visible = false;

Two options:

char c1 = '\u0001';
char c1 = (char) 1;

Another Idea...

 public class ViewModelBase : INotifyPropertyChanged
{
    private Dictionary<string, object> _propertyStore = new Dictionary<string, object>();
    protected virtual void SetValue<T>(T value, [CallerMemberName] string propertyName="") {
        _propertyStore[propertyName] = value;
        OnPropertyChanged(propertyName);
    }
    protected virtual T GetValue<T>([CallerMemberName] string propertyName = "")
    {
        object ret;
        if (_propertyStore.TryGetValue(propertyName, out ret))
        {
            return (T)ret;
        }
        else
        {
            return default(T);
        }
    }

    //Usage
    //public string SomeProperty {
    //    get { return GetValue<string>();  }
    //    set { SetValue(value); }
    //}

    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(string propertyName)
    {
        var temp = PropertyChanged;
        if (temp != null)
            temp.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

Easier than the above is

var today = new Date().toISOString().substring(0,10); # "2013-12-31"

OAuth is a protocol with which a 3-party app can access your data stored in another website without your account and password. For a more official definition, refer to the Wiki or specification.

Here is a use case demo:

1. I login to LinkedIn and want to connect some friends who are in my Gmail contacts. LinkedIn supports this. It will request a secure resource (my gmail contact list) from gmail. So I click this button:
   

2. A web page pops up, and it shows the Gmail login page, when I enter my account and password:
   

3. Gmail then shows a consent page where I click "Accept":

4. Now LinkedIn can access my contacts in Gmail:

Below is a flowchart of the example above:

Step 1: LinkedIn requests a token from Gmail's Authorization Server.

Step 2: The Gmail authorization server authenticates the resource owner and shows the user the consent page. (the user needs to login to Gmail if they are not already logged-in)

Step 3: User grants the request for LinkedIn to access the Gmail data.

Step 4: the Gmail authorization server responds back with an access token.

Step 5: LinkedIn calls the Gmail API with this access token.

Step 6: The Gmail resource server returns your contacts if the access token is valid. (The token will be verified by the Gmail resource server)

You can get more from details about OAuth here.

Probably way too late but this is another option:

 $('body').popover({
    selector: '[rel=popover]',
    trigger: 'hover',
    html: true,
    content: function () {
        return $(this).parents('.row').first().find('.metaContainer').html();
    }
});

1)Right Click On drawable directory then go to new then go to vector assets 2)change asset type from clip art to local 3)browse your file 4)give size 5)then click next then done Your usable svg will be generated in drawable directory

the best method I could suggest is this

1. Download the wheel file from this location for your version of python

   • https://pypi.python.org/pypi/scipy

2. Move the file to your Main Drive eg C:>

3. Run Cmd and enter the following

   • pip install scipy-1.0.0rc1-cp36-none-win_amd64.whl

Please note this is the version I am using for my pyhton 3.6.2 it should install fine

you may want to run this command after to make sure all your python add ons are up to date

pip list --outdated

After failing with every available solution, I finally had workaround using recursion.

Code:

//Recursive function, pass duration in seconds
public void showToast(int duration) {
    if (duration <= 0)
        return;

    Toast.makeText(this, "Hello, it's a toast", Toast.LENGTH_LONG).show();
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            showToast(duration-1);
        }
    }, 1000);
}

I'm also in the middle of trying to understand how this all connects.

Here's what I've found so far in XCode, but I hope to be corrected or affirmed if my assumptions are correct. I haven't found an out of the box build to xcode from cordova that correctly applies the icons. Like you I've updated all the icons listed in the config.xml but no dice.

So...

First, I usually update the config.xml in the root of the project with the one in my "www" folder (this I do out of uncertainty that the www/config.xml has any precedence or if it's even applied)

Second, I update the "Build Phases" of the project. Expand "Copy Bundle Resources", you've already noticed all of the images in "Resources/icons", "Resources/splash". You can either:

• remove all of these to avoid overwriting your images OR
• update all of these images with your own (renaming to the image name listed)

As I was working this out, you might be able to minimally just update images from the "Summary" tab.

Drag-and-drop your images from your res folders to the appropriate image in the "Summary" tab. (res/icon/ios -> App icons and res/screen/ios -> Launch Images). I do it only for iPhone since my app is iPhone only. Check "prerendered" if you don't want gloss to appear.

Then update the "icon.png" referenced in the project's plist file: PROJECT_NAME-Info.plist or in the "Info" tab when looking at the project target. Rename it to "icon-57.png" (that now lives in your project root, this was automatically added to the root when you did the drag-and-drop.

Build and you should an updated app icon.

Another method could be to split the string by ":" and then pop off the end. var newString = string.split(":").pop();

When searching folders where you might get an error based on security (e.g. C:\Users), use the following command:

Get-ChildItem -Path V:\Myfolder -Filter CopyForbuild.bat -Recurse -ErrorAction SilentlyContinue -Force

We can add drawable .xml like below

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


    <stroke
        android:width="1dp"
        android:color="@color/color_C4CDD5"/>

    <corners android:radius="8dp"/>

    <solid
        android:color="@color/color_white"/>

</shape>

Try this (faster and simpler):

newData <- data^2

checkout these easy to use Kotlin extensions for date format

fun String.getStringDate(initialFormat: String, requiredFormat: String, locale: Locale = Locale.getDefault()): String {
    return this.toDate(initialFormat, locale).toString(requiredFormat, locale)
}

fun String.toDate(format: String, locale: Locale = Locale.getDefault()): Date = SimpleDateFormat(format, locale).parse(this)

fun Date.toString(format: String, locale: Locale = Locale.getDefault()): String {
    val formatter = SimpleDateFormat(format, locale)
    return formatter.format(this)
}

For security reasons, it is not possible to get the real, full path of a file, referred through an <input type="file" /> element.

This question already mentions, and links to other Stack Overflow questions regarding this topic.

string = string.split("\\");

In JavaScript, the backslash is used to escape special characters, such as newlines (\n). If you want to use a literal backslash, a double backslash has to be used.

So, if you want to match two backslashes, four backslashes has to be used. For example,alert("\\\\") will show a dialog containing two backslashes.

You need to set the responseType to arraybuffer if you would like to create a blob from your response data:

$http.post('/fetchBlobURL',{myParams}, {responseType: 'arraybuffer'})
   .success(function (data) {
       var file = new Blob([data], {type: 'application/pdf'});
       var fileURL = URL.createObjectURL(file);
       window.open(fileURL);
});

I think that if you put a span style after the <a> tag with text-decoration:none it will work in the majority of the browsers / email clients.

As in:

<a href="" style="text-decoration:underline">
    <span style="color:#0b92ce; text-decoration:none">BANANA</span>
</a>

Unicode is not an encoding - to quote Kumar McMillan:

If ASCII, UTF-8, and other byte strings are "text" ...

...then Unicode is "text-ness";

it is the abstract form of text

Have a read of McMillan's Unicode In Python, Completely Demystified talk from PyCon 2008, it explains things a lot better than most of the related answers on Stack Overflow.

How a character is represented is up to the renderer, but the server may also strip out certain characters before sending the document.

You can also have untitled YouTube videos like https://www.youtube.com/watch?v=dmBvw8uPbrA by using the Unicode character ZERO WIDTH NON-JOINER (U+200C), or ‌ in HTML. The code block below should contain that character:

?? 

Using some ES6:

Get the options first, filter the value based on the option and set the selected attribute to true.

window.onload = () => {_x000D_
_x000D_
  Array.from(document.querySelector(`#Mobility`).options)_x000D_
    .filter(x => x.value === "12")[0]_x000D_
    .setAttribute('selected', true);_x000D_
_x000D_
};

<select style="width: 280px" id="Mobility" name="Mobility">_x000D_
  <option selected disabled>Please Select</option>_x000D_
  <option>K</option>_x000D_
  <option>1</option>_x000D_
  <option>2</option>_x000D_
  <option>3</option>_x000D_
  <option>4</option>_x000D_
  <option>5</option>_x000D_
  <option>6</option>_x000D_
  <option>7</option>_x000D_

  <option>10</option>_x000D_
  <option>11</option>_x000D_
  <option>12</option>_x000D_
</select>

I feel it is straightforward, without all this negative paddings or storks.

For global functions you can use this one instead of eval suggested in one of the answers.

var global = (function (){
    return this;
})();

if (typeof(global.f) != "function")
    global.f = function f1_shim (){
        // commonly used by polyfill libs
    };

You can use global.f instanceof Function as well, but afaik. the value of the Function will be different in different frames, so it will work only with a single frame application properly. That's why we usually use typeof instead. Note that in some environments there can be anomalies with typeof f too, e.g. by MSIE 6-8 some of the functions for example alert had "object" type.

By local functions you can use the one in the accepted answer. You can test whether the function is local or global too.

if (typeof(f) == "function")
    if (global.f === f)
        console.log("f is a global function");
    else
        console.log("f is a local function");

To answer the question, the example code is working for me without error in latest browers, so I am not sure what was the problem with it:

function something_cool(text, callback) {
    alert(text);
    if( callback != null ) callback();
}

Note: I would use callback !== undefined instead of callback != null, but they do almost the same.

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

for (Map.Entry<String, String> item : hashMap.entrySet()) {
    String key = item.getKey();
    String value = item.getValue();
}

Some of it is native, the rest is available through libraries.

For example Datejs is a good international date library.

For the rest, it's just about language translation, and JavaScript is natively Unicode compatible (as well as all major browsers).

Set your positional arguments with nargs, and check if positional args are empty.

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('file', nargs='?')
args = parser.parse_args()
if not args.file:
    parser.print_help()

Reference Python nargs

POSIX defines a function: wait(NULL);. It's the shorthand for waitpid(-1, NULL, 0);, which will suspends the execution of the calling process until any one child process exits. Here, 1st argument of waitpid indicates wait for any child process to end.

In your case, have the parent call it from within your else branch.

? 1. Can I set state inside a useEffect hook?

In principle, you can set state freely where you need it - including inside useEffect and even during rendering. Just make sure to avoid infinite loops by settting Hook deps properly and/or state conditionally.

? 2. Lets say I have some state that is dependent on some other state. Is it appropriate to create a hook that observes A and sets B inside the useEffect hook?

You just described the classic use case for useReducer:

useReducer is usually preferable to useState when you have complex state logic that involves multiple sub-values or when the next state depends on the previous one. (React docs)

When setting a state variable depends on the current value of another state variable, you might want to try replacing them both with useReducer. [...] When you find yourself writing setSomething(something => ...), it’s a good time to consider using a reducer instead. (Dan Abramov, Overreacted blog)

? 3. Will the effects cascade such that, when I click the button, the first effect will fire, causing b to change, causing the second effect to fire, before the next render?

useEffect always runs after the render is committed and DOM changes are applied. The first effect fires, changes b and causes a re-render. After this render has completed, second effect will run due to b changes.

? 4. Are there any performance downsides to structuring code like this?

Yes. By wrapping the state change of b in a separate useEffect for a, the browser has an additional layout/paint phase - these effects are potentially visible for the user. If there is no way you want give useReducer a try, you could change b state together with a directly:

let MyComponent = () => {_x000D_

  let [a, setA] = useState(1);_x000D_

You don't need regular expressions. Python has a built-in string method that does what you need:

mystring.replace(" ", "_")

tl;dr (this tl;dr is from @sp00m's answer below)

$emit dispatches an event upwards ... $broadcast dispatches an event downwards

Detailed explanation

$rootScope.$emit only lets other $rootScope listeners catch it. This is good when you don't want every $scope to get it. Mostly a high level communication. Think of it as adults talking to each other in a room so the kids can't hear them.

$rootScope.$broadcast is a method that lets pretty much everything hear it. This would be the equivalent of parents yelling that dinner is ready so everyone in the house hears it.

$scope.$emit is when you want that $scope and all its parents and $rootScope to hear the event. This is a child whining to their parents at home (but not at a grocery store where other kids can hear).

$scope.$broadcast is for the $scope itself and its children. This is a child whispering to its stuffed animals so their parents can't hear.

A little update for Bootstrap 3.

Bootstrap now has the following style for table cells:

.table tbody>tr>td
{
    vertical-align: top;
}

The way to go is to add a your own class, with the same selector:

.table tbody>tr>td.vert-align
{
    vertical-align: middle;
}

And then add it to your tds

<td class="vert-align"></td>

I have tried Alberthoven's example (hibernate-validator 4.0.2.GA) and i get an ValidationException: „Annotated methods must follow the JavaBeans naming convention. match() does not.“ too. After I renamed the method from „match“ to "isValid" it works.

public class Password {

    private String password;

    private String retypedPassword;

    public Password(String password, String retypedPassword) {
        super();
        this.password = password;
        this.retypedPassword = retypedPassword;
    }

    @AssertTrue(message="password should match retyped password")
    private boolean isValid(){
        if (password == null) {
            return retypedPassword == null;
        } else {
            return password.equals(retypedPassword);
        }
    }

    public String getPassword() {
        return password;
    }

    public String getRetypedPassword() {
        return retypedPassword;
    }

}

Byterbit solution is problematic because:

1. having the client control expiration of a server side cookie is a security issue.
2. if expiration timeout set on server side is smaller than the timeout set on client side, the page would not reflect the actual state of the cookie.
3. even if for the sake of comfort in development stage, this is a problem because it won't reflect the right behaviour (in timing) on release stage.

for cookies, setting expiration via session.cookie_lifetime is the right solution design-wise and security-wise! for expiring the session, you can use session.gc_maxlifetime.

expiring the cookies by calling session_destroy might yield unpredictable results because they might have already been expired.

making the change in php.ini is also a valid solution but it makes the expiration global for the entire domain which might not be what you really want - some pages might choose to keep some cookies more than others.

Your array is occupying roughly 8 GB of memory (1,000 x 1,000,000 x sizeof(double) bytes). That might be a factor in your problem. It is a global variable rather than a stack variable, so you may be OK, but you're pushing limits here.

Writing that much data to a file is going to take a while.

You don't check that the file was opened successfully, which could be a source of trouble, too (if it did fail, a segmentation fault is very likely).

You really should introduce some named constants for 1,000 and 1,000,000; what do they represent?

You should also write a function to do the calculation; you could use an inline function in C99 or later (or C++). The repetition in the code is excruciating to behold.

You should also use C99 notation for main(), with the explicit return type (and preferably void for the argument list when you are not using argc or argv):

int main(void)

Out of idle curiosity, I took a copy of your code, changed all occurrences of 1000 to ROWS, all occurrences of 1000000 to COLS, and then created enum { ROWS = 1000, COLS = 10000 }; (thereby reducing the problem size by a factor of 100). I made a few minor changes so it would compile cleanly under my preferred set of compilation options (nothing serious: static in front of the functions, and the main array; file becomes a local to main; error check the fopen(), etc.).

I then created a second copy and created an inline function to do the repeated calculation, (and a second one to do subscript calculations). This means that the monstrous expression is only written out once — which is highly desirable as it ensure consistency.

#include <stdio.h>

#define   lambda   2.0
#define   g        1.0
#define   F0       1.0
#define   h        0.1
#define   e        0.00001

enum { ROWS = 1000, COLS = 10000 };

static double F[ROWS][COLS];

static void Inicio(double D[ROWS][COLS])
{
    for (int i = 399; i < 600; i++) // Magic numbers!!
        D[i][0] = F0;
}

enum { R = ROWS - 1 };

static inline int ko(int k, int n)
{
    int rv = k + n;
    if (rv >= R)
        rv -= R;
    else if (rv < 0)
        rv += R;
    return(rv);
}

static inline void calculate_value(int i, int k, double A[ROWS][COLS])
{
    int ks2 = ko(k, -2);
    int ks1 = ko(k, -1);
    int kp1 = ko(k, +1);
    int kp2 = ko(k, +2);

    A[k][i] = A[k][i-1]
            + e/(h*h*h*h) * g*g * (A[kp2][i-1] - 4.0*A[kp1][i-1] + 6.0*A[k][i-1] - 4.0*A[ks1][i-1] + A[ks2][i-1])
            + 2.0*g*e/(h*h) * (A[kp1][i-1] - 2*A[k][i-1] + A[ks1][i-1])
            + e * A[k][i-1] * (lambda - A[k][i-1] * A[k][i-1]);
}

static void Iteration(double A[ROWS][COLS])
{
    for (int i = 1; i < COLS; i++)
    {
        for (int k = 0; k < R; k++)
            calculate_value(i, k, A);
        A[999][i] = A[0][i];
    }
}

int main(void)
{
    FILE *file = fopen("P2.txt","wt");
    if (file == 0)
        return(1);
    Inicio(F);
    Iteration(F);
    for (int i = 0; i < COLS; i++)
    {
        for (int j = 0; j < ROWS; j++)
        {
            fprintf(file,"%lf \t %.4f \t %lf\n", 1.0*j/10.0, 1.0*i, F[j][i]);
        }
    }
    fclose(file);
    return(0);
}

This program writes to P2.txt instead of P1.txt. I ran both programs and compared the output files; the output was identical. When I ran the programs on a mostly idle machine (MacBook Pro, 2.3 GHz Intel Core i7, 16 GiB 1333 MHz RAM, Mac OS X 10.7.5, GCC 4.7.1), I got reasonably but not wholly consistent timing:

6.315s     10.778s

However, almost all that time is spent on disk I/O. I reduced the disk I/O to just the very last row of data, so the outer I/O for loop became:

for (int i = COLS - 1; i < COLS; i++)

the timings were vastly reduced and very much more consistent:

Original    Modified
0.168s      0.165s
0.145s      0.165s
0.165s      0.166s

0.171s      0.165s
0.151s      0.169s

The simplification in the code from having the ghastly expression written out just once is very beneficial, it seems to me. I'd certainly far rather have to maintain that program than the original.

UPDATE: this is not the solution but it's a workaround for a problem that can cause the exception presented in the question.

I've solved changing from Release Configuration to Debug Configuration.

It may not be an easy problem. Determining how to map classes defined in Python into types in Java will be a big challange because of differences in each of type binding time. (duck typing vs. compile time binding).

This doesn't work because NaN isn't equal to anything, including NaN. Use pd.isnull(df.var2) instead.

Note you can do something like this(at least in MVC3):

<td align="left" @(isOddRow ? "class=TopBorder" : "style=border:0px") >

What I believed was razor adding quotes was actually the browser. As Rism pointed out when testing with MVC 4(I haven't tested with MVC 3 but I assume behavior hasn't changed), this actually produces class=TopBorder but browsers are able to parse this fine. The HTML parsers are somewhat forgiving on missing attribute quotes, but this can break if you have spaces or certain characters.

<td align="left" class="TopBorder" >

OR

<td align="left" style="border:0px" >

What goes wrong with providing your own quotes

If you try to use some of the usual C# conventions for nested quotes, you'll end up with more quotes than you bargained for because Razor is trying to safely escape them. For example:

<button type="button" @(true ? "style=\"border:0px\"" : string.Empty)>

This should evaluate to <button type="button" style="border:0px"> but Razor escapes all output from C# and thus produces:

style="border:0px"

You will only see this if you view the response over the network. If you use an HTML inspector, often you are actually seeing the DOM, not the raw HTML. Browsers parse HTML into the DOM, and the after-parsing DOM representation already has some niceties applied. In this case the Browser sees there aren't quotes around the attribute value, adds them:

style=""border:0px""

But in the DOM inspector HTML character codes display properly so you actually see:

style=""border:0px""

In Chrome, if you right-click and select Edit HTML, it switch back so you can see those nasty HTML character codes, making it clear you have real outer quotes, and HTML encoded inner quotes.

So the problem with trying to do the quoting yourself is Razor escapes these.

If you want complete control of quotes

Use Html.Raw to prevent quote escaping:

<td @Html.Raw( someBoolean ? "rel='tooltip' data-container='.drillDown a'" : "" )>

Renders as:

<td rel='tooltip' title='Drilldown' data-container='.drillDown a'>

The above is perfectly safe because I'm not outputting any HTML from a variable. The only variable involved is the ternary condition. However, beware that this last technique might expose you to certain security problems if building strings from user supplied data. E.g. if you built an attribute from data fields that originated from user supplied data, use of Html.Raw means that string could contain a premature ending of the attribute and tag, then begin a script tag that does something on behalf of the currently logged in user(possibly different than the logged in user). Maybe you have a page with a list of all users pictures and you are setting a tooltip to be the username of each person, and one users named himself '/><script>$.post('changepassword.php?password=123')</script> and now any other user who views this page has their password instantly changed to a password that the malicious user knows.

JSON has no functions as data types. You can only serialize strings, numbers, objects, arrays, and booleans (and null)

You could create your own toJson method, only passing the data that really has to be serialized:

Person.prototype.toJson = function() {
    return JSON.stringify({age: this.age});
};

Similar for deserializing:

Person.fromJson = function(json) {
    var data = JSON.parse(json); // Parsing the json string.
    return new Person(data.age);
};

The usage would be:

var serialize = p1.toJson();
var _p1 = Person.fromJson(serialize);
alert("Is old: " + _p1.isOld());

To reduce the amount of work, you could consider to store all the data that needs to be serialized in a special "data" property for each Person instance. For example:

function Person(age) {
    this.data = {
        age: age
    };
    this.isOld = function (){
        return this.data.age > 60 ? true : false;
    }
}

then serializing and deserializing is merely calling JSON.stringify(this.data) and setting the data of an instance would be instance.data = JSON.parse(json).

This would keep the toJson and fromJson methods simple but you'd have to adjust your other functions.

Side note:

You should add the isOld method to the prototype of the function:

Person.prototype.isOld = function() {}

Otherwise, every instance has it's own instance of that function which also increases memory.

Its easy, just wrap it in a relative box like so:

<div class="relative">
 <div class="absolute">LOGO</div>
</div>

The relative box has a margin: 0 Auto; and, important, a width...

I agree that Pascal's solution is the way to go, but for those saying that it adds an extra task to remove the comments, you can use the following comment style trick to simplify your life:

<?php /* ?>
<tr>
      <td><?php echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php echo $sort_order; ?>" size="1" /></td>
    </tr>
<?php // */ ?>

In order to stop the code block being commented out, simply change the opening comment to:

<?php //* ?>

hi friend please try this expression your report

="Page " + Globals!PageNumber.ToString() + " of " + Globals!OverallTotalPages.ToString() + vbcrlf + "Generated: " + Globals!ExecutionTime.ToString()

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

Try LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0). Best of all it's free!

Steps with version 4.35.1:

1. click 'Add Connection'

2. Click Next with 'Build data context automatically' and 'Default(LINQ to SQL)' selected.

3. Under 'Provider' choose 'SQL CE 4.0'.

4. Under 'Database' with 'Attach database file' selected, choose 'Browse' to select your .sdf file.

5. Click 'OK'.

6. Voila! It should show the tables in .sdf and be able to query it via right clicking the table or writing LINQ code in your favorite .NET language or even SQL. How cool is that?

Adding the GridView1.DataBind() to the button click event did not work for me. However, adding it to the SqlDataSource1_Updated event did though.

Protected Sub SqlDataSource1_Updated(sender As Object, e As SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Updated
    GridView1.DataBind()
End Sub

It is just a typo(I guess)-

p+=1;

instead of p +1=p; is required .

As name suggest lvalue expression should be left-hand operand of the assignment operator.

Hopefully this would get you started

Output:

Field 3 would be nazwisko
Field 3 would be Kowalski
Field 3 would be Nowak

I'm still experiencing this behavior with jQuery 1.7.2. A simple workaround is to defer the execution of the click handler with setTimeout and let the browser do its magic in the meantime:

$("#myCheckbox").click( function() {
    var that = this;
    setTimeout(function(){
        alert($(that).is(":checked"));
    });
});

I have a GitHub Gist with a Java like UUID implementation in C#: https://gist.github.com/rickbeerendonk/13655dd24ec574954366

The UUID can be created from the least and most significant bits, just like in Java. It also exposes them. The implementation has an explicit conversion to a GUID and an implicit conversion from a GUID.

and if nothing helps and you still want to present that website in an iframe consider using X Frame Bypass Component which will utilize a proxy.

When using with a reactive bootstrap table, i did not find that the

table.classname td {

syntax worked as there was no <table> tag at all. Often modules like this don't use the outer tag but just dive right in maybe using <thead> and <tbody> for grouping at most.

Simply specifying like this worked great though

td.classname {
    max-width: 500px;
    text-overflow: initial;
    white-space: wrap;
    word-wrap: break-word;
}

as it directly overrides the <td> and can be used only on the elements you want to change. Maybe in your case use

thead.medium td {
  font-size: 40px; 
}
tbody.small td {
  font-size:25px;
}

for consistent font sizing with a bigger header.

import logging

# Only show warnings
logging.getLogger("urllib3").setLevel(logging.WARNING)

# Disable all child loggers of urllib3, e.g. urllib3.connectionpool
logging.getLogger("urllib3").propagate = False

For my case, I deleted the mappedBy and joined tables like this:

@ManyToMany(cascade = CascadeType.ALL)
@JoinTable(name = "user_group", joinColumns = {
        @JoinColumn(name = "user", referencedColumnName = "user_id")
}, inverseJoinColumns = {
        @JoinColumn(name = "group", referencedColumnName = "group_id")
})
private List<User> users;

@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JsonIgnore
private List<Group> groups;

This should do the trick.....

reset($array);
while (list($elementKey, $element) = each($array)) {
    while (list($key, $value2) = each($element)) {
        if($key == 'id' && $value == 'searched_value') {
            unset($array[$elementKey]);
        }
    }
}

Another Solution in Case You Don't Have Control Over Dynamic Content

This works if you didn't load your element through a directive (ie. like in the example in the commented jsfiddles).

Wrap up Your Content

Wrap your content in a div so that you can select it if you are using JQuery. You an also opt to use native javascript to get your element.

<div class="selector">
    <grid-filter columnname="LastNameFirstName" gridname="HomeGrid"></grid-filter>
</div>

Use Angular Injector

You can use the following code to get a reference to $compile if you don't have one.

$(".selector").each(function () {
    var content = $(this);
    angular.element(document).injector().invoke(function($compile) {
        var scope = angular.element(content).scope();
        $compile(content)(scope);
    });
});

Summary

The original post seemed to assume you had a $compile reference handy. It is obviously easy when you have the reference, but I didn't so this was the answer for me.

One Caveat of the previous code

If you are using a asp.net/mvc bundle with minify scenario you will get in trouble when you deploy in release mode. The trouble comes in the form of Uncaught Error: [$injector:unpr] which is caused by the minifier messing with the angular javascript code.

Here is the way to remedy it:

Replace the prevous code snippet with the following overload.

...
angular.element(document).injector().invoke(
[
    "$compile", function($compile) {
        var scope = angular.element(content).scope();
        $compile(content)(scope);
    }
]);
...

This caused a lot of grief for me before I pieced it together.

for people who need CGO enabled and cross compile from OSX targeting windows

I needed CGO enabled while compiling for windows from my mac since I had imported the https://github.com/mattn/go-sqlite3 and it needed it. Compiling according to other answers gave me and error:

/usr/local/go/src/runtime/cgo/gcc_windows_amd64.c:8:10: fatal error: 'windows.h' file not found

If you're like me and you have to compile with CGO. This is what I did:

1.We're going to cross compile for windows with a CGO dependent library. First we need a cross compiler installed like mingw-w64

brew install mingw-w64

This will probably install it here /usr/local/opt/mingw-w64/bin/.

2.Just like other answers we first need to add our windows arch to our go compiler toolchain now. Compiling a compiler needs a compiler (weird sentence) compiling go compiler needs a separate pre-built compiler. We can download a prebuilt binary or build from source in a folder eg: ~/Documents/go now we can improve our Go compiler, according to top answer but this time with CGO_ENABLED=1 and our separate prebuilt compiler GOROOT_BOOTSTRAP(Pooya is my username):

cd /usr/local/go/src
sudo GOOS=windows GOARCH=amd64 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean
sudo GOOS=windows GOARCH=386 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean

3.Now while compiling our Go code use mingw to compile our go file targeting windows with CGO enabled:

GOOS="windows" GOARCH="386" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/i686-w64-mingw32-gcc" go build hello.go
GOOS="windows" GOARCH="amd64" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/x86_64-w64-mingw32-gcc" go build hello.go

I found from event logs that My SQL server evaluation has expired. I needed to upgrade or needed to use community edition.

THIS IS JUST A NOTE FOR ANYONE DEALING WITH THIS PROBLEM USING THE RUBY DRIVER

I had this same problem when using the Ruby Gem.

To set slaveOk in Ruby, you just pass it as an argument when you create the client like this:

mongo_client = MongoClient.new("localhost", 27017, { slave_ok: true })

https://github.com/mongodb/mongo-ruby-driver/wiki/Tutorial#making-a-connection

mongo_client = MongoClient.new # (optional host/port args)

Notice that 'args' is the third optional argument.

It is quite simple to understand the question, but to answer it we need to dig deeper in to Java native code.

• System is static class and cannot be instantiated
• out is a reference variable defined in System
• println() is the method used to print on standard output.

A brief and nice explanation is always welcome on this as we can learn much from this single line of statement itself!

This came across while working on a project on linux platform.

exec('wget http://<url to the php script>)

This runs as if you run the script from browser.

Hope this helps!!

@fooMonster article worked for me

# git ls-tree HEAD
100644 blob 55c0287d4ef21f15b97eb1f107451b88b479bffe    script.sh

As you can see the file has 644 permission (ignoring the 100). We would like to change it to 755:

# git update-index --chmod=+x script.sh

commit the changes

# git commit -m "Changing file permissions"
[master 77b171e] Changing file permissions
0 files changed, 0 insertions(+), 0 deletions(-)
mode change 100644 => 100755 script.sh

You need to have installed Microsoft Visual Studio Tools for Office (VSTO).

VSTO can be selected in the Visual Studio installer under Workloads > Web & Cloud > Office/SharePoint Development.

After that create common .NET project and add the reference to Microsoft.Office.Interop.Excel via 'Add Reference... > Assemblies' dialog.

Application excel = new Application();
Workbook wb = excel.Workbooks.Open(path);

Missing.Value is a special reflection struct for unnecessary parameters replacement

In newer versions, the assembly reference required is called Microsoft Excel 16.0 Object Library. If you do not have the latest version installed you might have Microsoft Excel 15.0 Object Library, or an older version, but it is the same process to include.

Use the split function.

static void Main(string[] args)
{
    string s = "223232-1.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "443-2.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "34443553-5.jpg";
    Console.WriteLine(s.Split('-')[0]);

Console.ReadKey();
}

If your string doesn't have a - then you'll get the whole string.

I realize that this question is over 10 years old, but it appears to me that not only has the most obvious answer not been addressed, but that maybe its not really clear from the question a good understanding of what goes on under the covers. In addition, there are other questions about late binding and what that means with regards to delegates and lambdas (more on that later).

First to address the 800 lb elephant/gorilla in the room, when to choose event vs Action<T>/Func<T>:

• Use a lambda to execute one statement or method. Use event when you want more of a pub/sub model with multiple statements/lambdas/functions that will execute (this is a major difference right off the bat).
• Use a lambda when you want to compile statements/functions to expression trees. Use delegates/events when you want to participate in more traditional late binding such as used in reflection and COM interop.

As an example of an event, lets wire up a simple and 'standard' set of events using a small console application as follows:

public delegate void FireEvent(int num);

public delegate void FireNiceEvent(object sender, SomeStandardArgs args);

public class SomeStandardArgs : EventArgs
{
    public SomeStandardArgs(string id)
    {
        ID = id;
    }

    public string ID { get; set; }
}

class Program
{
    public static event FireEvent OnFireEvent;

    public static event FireNiceEvent OnFireNiceEvent;


    static void Main(string[] args)
    {
        OnFireEvent += SomeSimpleEvent1;
        OnFireEvent += SomeSimpleEvent2;

        OnFireNiceEvent += SomeStandardEvent1;
        OnFireNiceEvent += SomeStandardEvent2;


        Console.WriteLine("Firing events.....");
        OnFireEvent?.Invoke(3);
        OnFireNiceEvent?.Invoke(null, new SomeStandardArgs("Fred"));

        //Console.WriteLine($"{HeightSensorTypes.Keyence_IL030}:{(int)HeightSensorTypes.Keyence_IL030}");
        Console.ReadLine();
    }

    private static void SomeSimpleEvent1(int num)
    {
        Console.WriteLine($"{nameof(SomeSimpleEvent1)}:{num}");
    }
    private static void SomeSimpleEvent2(int num)
    {
        Console.WriteLine($"{nameof(SomeSimpleEvent2)}:{num}");
    }

    private static void SomeStandardEvent1(object sender, SomeStandardArgs args)
    {

        Console.WriteLine($"{nameof(SomeStandardEvent1)}:{args.ID}");
    }
    private static void SomeStandardEvent2(object sender, SomeStandardArgs args)
    {
        Console.WriteLine($"{nameof(SomeStandardEvent2)}:{args.ID}");
    }
}

The output will look as follows:

If you did the same with Action<int> or Action<object, SomeStandardArgs>, you would only see SomeSimpleEvent2 and SomeStandardEvent2.

So whats going on inside of event?

If we expand out FireNiceEvent, the compiler is actually generating the following (I have omitted some details with respect to thread synchronization that isn't relevant to this discussion):

   private EventHandler<SomeStandardArgs> _OnFireNiceEvent;

    public void add_OnFireNiceEvent(EventHandler<SomeStandardArgs> handler)
    {
        Delegate.Combine(_OnFireNiceEvent, handler);
    }

    public void remove_OnFireNiceEvent(EventHandler<SomeStandardArgs> handler)
    {
        Delegate.Remove(_OnFireNiceEvent, handler);
    }

    public event EventHandler<SomeStandardArgs> OnFireNiceEvent
    {
        add
        {
            add_OnFireNiceEvent(value)
        }
        remove
        {
            remove_OnFireNiceEvent(value)

        }
    }

The compiler generates a private delegate variable which is not visible to the class namespace in which it is generated. That delegate is what is used for subscription management and late binding participation, and the public facing interface is the familiar += and -= operators we have all come to know and love : )

You can customize the code for the add/remove handlers by changing the scope of the FireNiceEvent delegate to protected. This now allows developers to add custom hooks to the hooks, such as logging or security hooks. This really makes for some very powerful features that now allows for customized accessibility to subscription based on user roles, etc. Can you do that with lambdas? (Actually you can by custom compiling expression trees, but that's beyond the scope of this response).

To address a couple of points from some of the responses here:

• There really is no difference in the 'brittleness' between changing the args list in Action<T> and changing the properties in a class derived from EventArgs. Either will not only require a compile change, they will both change a public interface and will require versioning. No difference.

• With respect to which is an industry standard, that depends on where this is being used and why. Action<T> and such is often used in IoC and DI, and event is often used in message routing such as GUI and MQ type frameworks. Note that I said often, not always.

• Delegates have different lifetimes than lambdas. One also has to be aware of capture... not just with closure, but also with the notion of 'look what the cat dragged in'. This does affect memory footprint/lifetime as well as management a.k.a. leaks.

One more thing, something I referenced earlier... the notion of late binding. You will often see this when using framework like LINQ, regarding when a lambda becomes 'live'. That is very different than late binding of a delegate, which can happen more than once (i.e. the lambda is always there, but binding occurs on demand as often as is needed), as opposed to a lambda, which once it occurs, its done -- the magic is gone, and the method(s)/property(ies) will always bind. Something to keep in mind.

Before enabling the My Location layer, you must request location permission from the user. This sample does not include a request for location permission.

To simplify, in terms of lines of code, the request for the location permit can be made using the library EasyPermissions.

Then following the example of the official documentation of The My Location Layer my code works as follows for all versions of Android that contain Google services.

1. Create an activity that contains a map and implements the interfaces OnMyLocationClickListener y OnMyLocationButtonClickListener.
2. Define in app/build.gradle implementation 'pub.devrel:easypermissions:2.0.1'

3. Forward results to EasyPermissions within method onRequestPermissionsResult()

   EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);

4. Request permission and operate according to the user's response with requestLocationPermission()

5. Call requestLocationPermission() and set the listeners to onMapReady().

MapsActivity.java

public class MapsActivity extends FragmentActivity implements 
    OnMapReadyCallback,
    GoogleMap.OnMyLocationClickListener,
    GoogleMap.OnMyLocationButtonClickListener {

    private final int REQUEST_LOCATION_PERMISSION = 1;

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        requestLocationPermission();
        mMap.setOnMyLocationButtonClickListener(this);
        mMap.setOnMyLocationClickListener(this);
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        // Forward results to EasyPermissions
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }

    @SuppressLint("MissingPermission")
    @AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            mMap.setMyLocationEnabled(true);
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }

    @Override
    public boolean onMyLocationButtonClick() {
        Toast.makeText(this, "MyLocation button clicked", Toast.LENGTH_SHORT).show();
        return false;
    }

    @Override
    public void onMyLocationClick(@NonNull Location location) {
        Toast.makeText(this, "Current location:\n" + location, Toast.LENGTH_LONG).show();
    }
}

I know this is an older thread however I needed to write a function that returned the first blank row WITHIN a range. All of the code I found online actually searches the entire row (even the cells outside of the range) for a blank row. Data in ranges outside the search range was triggering a used row. This seemed to me to be a simple solution:

Function FirstBlankRow(ByVal rngToSearch As Range) As Long
   Dim R As Range
   Dim C As Range
   Dim RowIsBlank As Boolean

   For Each R In rngToSearch.Rows
      RowIsBlank = True
      For Each C In R.Cells
         If IsEmpty(C.Value) = False Then RowIsBlank = False
      Next C
      If RowIsBlank Then
         FirstBlankRow = R.Row
         Exit For
      End If
   Next R
End Function

After going through all the answers I thought i will add two simple options

1. If you already accessed the record using FirstOrDefault() with tracking enabled (without using .AsNoTracking() function as it will disable tracking) and updated some fields then you can simply call context.SaveChanges()

2. In other case either you have entity posted to server using HtppPost or you disabled tracking for some reason then you should call context.Update(entityName) before context.SaveChanges()

1st option will only update the fields you changed but 2nd option will update all the fields in the database even though none of the field values were actually updated :)

Similar to Nick's contribution, I came to the same solution for reindexing an array, but enhanced the function a little since from PHP version 5.4, it doesn't work because of passing variables by reference. Example reindexing function is then like this using use keyword closure:

function indexArrayByElement($array, $element)
{
    $arrayReindexed = [];
    array_walk(
        $array,
        function ($item, $key) use (&$arrayReindexed, $element) {
            $arrayReindexed[$item[$element]] = $item;
        }
    );
    return $arrayReindexed;
}

Both methods do the same functionally - they compare values.
As is written on MSDN:

• About String.Equals method - Determines whether this instance and another specified String object have the same value. (http://msdn.microsoft.com/en-us/library/858x0yyx.aspx)
• About == - Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references. This makes testing for string equality more intuitive. (http://msdn.microsoft.com/en-en/library/362314fe.aspx)

But if one of your string instances is null, these methods are working differently:

string x = null;
string y = "qq";
if (x == y) // returns false
    MessageBox.Show("true");
else
    MessageBox.Show("false");

if (x.Equals(y)) // returns System.NullReferenceException: Object reference not set to an instance of an object. - because x is null !!!
    MessageBox.Show("true");
else
    MessageBox.Show("false");

In curl request add time out 0 so its infinite time set like CURLOPT_TIMEOUT set 0

newString = yourString.Substring(0, yourString.length -1);

Your list:

List<MyCustomObject> myCustomObjectList;

Your JSONArray:

// Don't need to loop through it. JSONArray constructor do it for you.
new JSONArray(myCustomObjectList)

Your response:

return new JSONObject().put("yourCustomKey", new JSONArray(myCustomObjectList));

Your post/put http body request would be like this:

    {
        "yourCustomKey: [
           {
               "myCustomObjectProperty": 1
           },
           {
               "myCustomObjectProperty": 2
           }
        ]
    }

The String conversion page on the Coder's Toolbox site is handy for encoding more than a small amount of HTML or XML code for inclusion as a value in an XML element.

Online PHP lint

PHPLint

Unitialized variables check. Link 1 and 2 already seem to do this just fine, though.

I can't say I have used any of these intensively, though :)

$mail = new PHPMailer();
$mail->CharSet = "UTF-8";
$mail->Encoding = "16bit";

A very simple solution using jQuery:

on the client side:

$('.act_download_statement').click(function(e){
    e.preventDefault();
    form = $('#my_form');
    form.submit();
});

and on the server side, make sure you send back the correct Content-Type header, so the browser will know its an attachment and the download will begin.

If your options are like this

var options = [
  { value: 'one', label: 'One' },
  { value: 'two', label: 'Two' }
];

Your {props.input.value} should match one of the 'value' in your {props.options}

Meaning, props.input.value should be either 'one' or 'two'

I hope this is one of the basic conditional classes

Solution: 1

<section [ngClass]="(condition)? 'class1 class2 ... classN' : 'another class1 ... classN' ">

Solution 2

<section [ngClass]="(condition)? 'class1 class2 ... classN' : '(condition)? 'class1 class2 ... classN':'another class' ">

Solution 3

<section [ngClass]="'myclass': condition, 'className2': condition2">

Unlike the id selector, the class selector is most often used on several elements.
This allows you to set a particular style for many HTML elements with the same class.

The class selector uses the HTML class attribute, and is defined with a "."
A simple way to look at it is that an id is unique to only one element. class is better to use as it will help you to execute what ever you want.

The __init__.py files are required to make Python treat the directories as containing packages, this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

__init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable.

If you can't seem to use some of the newer functions, here's something I whipped up. Probably more than you need, and I'm sure there are better ways, but it's easy to read, so it should do the job:

function get_age($date, $units='years')
{
    $modifier = date('n') - date('n', strtotime($date)) ? 1 : (date('j') - date('j', strtotime($date)) ? 1 : 0);
    $seconds = (time()-strtotime($date));
    $years = (date('Y')-date('Y', strtotime($date))-$modifier);
    switch($units)
    {
        case 'seconds':
            return $seconds;
        case 'minutes':
            return round($seconds/60);
        case 'hours':
            return round($seconds/60/60);
        case 'days':
            return round($seconds/60/60/24);
        case 'months':
            return ($years*12+date('n'));
        case 'decades':
            return ($years/10);
        case 'centuries':
            return ($years/100);
        case 'years':
        default:
            return $years;
    }
}

Example Use:

echo 'I am '.get_age('September 19th, 1984', 'days').' days old';

Hope this helps.

To get min/max value in array, you can use:

var _array = [1,3,2];
Math.max.apply(Math,_array); // 3
Math.min.apply(Math,_array); // 1

Go to File > Preferences > Settings (or press Ctrl+,) then click the leftmost icon in the top right corner, "Open Settings (JSON)"

In the JSON settings window, add this (within the curly braces {}):

"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\bash.exe"`

(Here you can put any other custom settings you want as well)

Checkout that path to make sure your bash.exe file is there otherwise find out where it is and point to that path instead.

Now if you open a new terminal window in VS Code, it should open with bash instead of PowerShell.

To view your recent work and what branch it happened on run

Where n (in the above sample) is that number corresponding to the Work In Progress.

Well how to find dates between two given date in SQL server is explain on http://ektaraval.blogspot.com/2010/09/writing-recursive-query-to-find-out-all.html

first import os module in your app than with use from getpid function get pid's app and save in a file.for example :

import os
pid = os.getpid()
op = open("/var/us.pid","w")
op.write("%s" % pid)
op.close()

and create a bash file in /etc/init.d path: /etc/init.d/servername

PATHAPP="/etc/bin/userscript.py &"
PIDAPP="/var/us.pid"
case $1 in 
        start)
                echo "starting"
                $(python $PATHAPP)
        ;;
        stop)
                echo "stoping"
                PID=$(cat $PIDAPP)
                kill $PID
        ;;

esac

now , u can start and stop ur app with down command:

service servername stop service servername start

or

Old thread but I was having this issue and solved it by first grouping the, in my case, option buttons together that were having the issue then simply setting (resetting) the size of this group in an Auto_Open as such:

With ThisWorkbook
    .Worksheets("1").Shapes("grpInput").Width = 383.1
    .Worksheets("2").Shapes("grpSuite").Width = 383.1
    .Worksheets("3").Shapes("grpLoc").Width = 383.1
    .Worksheets("4").Shapes("grpDecision").Width = 383.1
End With

Line ending format used in OS

• Windows: CR (Carriage Return \r) and LF (LineFeed \n) pair
• OSX,Linux: LF (LineFeed \n)

We can configure git to auto-correct line ending formats for each OS in two ways.

1. Git Global configuration
2. Use .gitattributes file

Global Configuration

git config --global core.autocrlf input

This will fix any CRLF to LF when you commit.

git config --global core.autocrlf true

This will make sure when you checkout in windows, all LF will convert to CRLF

.gitattributes File

It is a good idea to keep a .gitattributes file as we don't want to expect everyone in our team set their config. This file should keep in repo's root path and if exist one, git will respect it.

* text=auto

This will treat all files as text files and convert to OS's line ending on checkout and back to LF on commit automatically. If wanted to tell explicitly, then use

* text eol=crlf
* text eol=lf

First one is for checkout and second one is for commit.

*.jpg binary

Treat all .jpg images as binary files, regardless of path. So no conversion needed.

Or you can add path qualifiers:

my_path/**/*.jpg binary

You can simply export the table with a query clause using datapump and import it back with table_exists_action=replace clause. Its will drop and recreate your table and take very less time. Please read about it before implementing.

In your code it should be

proc1.kill()

Both kill or terminate are methods of the Popen object which sends the signal signal.SIGKILL to the process.

@jing: "The DirectoryInfo solution is much faster then this (especially for network path)"

I cant confirm this. It seems as if Directory.GetFiles triggers a filesystem or network cache. The first request takes a while, but the following requests are much faster, even if new files were added. In my test I did a Directory.getfiles and a info.GetFiles with the same patterns and both run equally

GetFiles  done 437834 in00:00:20.4812480
process files  done 437834 in00:00:00.9300573
GetFiles by Dirinfo(2)  done 437834 in00:00:20.7412646

Jon's disassemblies show, that the difference between the two versions is that the fast version uses a pair of registers (esi,edi) to store one of the local variables where the slow version doesn't.

The JIT compiler makes different assumptions regarding register use for code that contains a try-catch block vs. code which doesn't. This causes it to make different register allocation choices. In this case, this favors the code with the try-catch block. Different code may lead to the opposite effect, so I would not count this as a general-purpose speed-up technique.

In the end, it's very hard to tell which code will end up running the fastest. Something like register allocation and the factors that influence it are such low-level implementation details that I don't see how any specific technique could reliably produce faster code.

For example, consider the following two methods. They were adapted from a real-life example:

interface IIndexed { int this[int index] { get; set; } }
struct StructArray : IIndexed { 
    public int[] Array;
    public int this[int index] {
        get { return Array[index]; }
        set { Array[index] = value; }
    }
}

static int Generic<T>(int length, T a, T b) where T : IIndexed {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}
static int Specialized(int length, StructArray a, StructArray b) {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}

One is a generic version of the other. Replacing the generic type with StructArray would make the methods identical. Because StructArray is a value type, it gets its own compiled version of the generic method. Yet the actual running time is significantly longer than the specialized method's, but only for x86. For x64, the timings are pretty much identical. In other cases, I've observed differences for x64 as well.

In .NET 4.5, you can use the CultureInfo.DefaultThreadCurrentCulture property to change the culture of an AppDomain.

For versions prior to 4.5 you have to use reflection to manipulate the culture of an AppDomain. There is a private static field on CultureInfo (m_userDefaultCulture in .NET 2.0 mscorlib, s_userDefaultCulture in .NET 4.0 mscorlib) that controls what CurrentCulture returns if a thread has not set that property on itself.

This does not change the native thread locale and it is probably not a good idea to ship code that changes the culture this way. It may be useful for testing though.

The new jQuery UI version will not allow you to call UI methods on dialog which is not initialized. As a workaround, you can use the below check to see if the dialog is alive.

if (modalDialogObj.hasClass('ui-dialog-content')) {
    // call UI methods like modalDialogObj.dialog('isOpen')
} else {
    // it is not initialized yet
}

If there is no such mechanism, what is a pattern/convention for such problems?

The term 'cleanup' might be more appropriate, but will use 'destructor' to match OP

Suppose you write some javascript entirely with 'function's and 'var's. Then you can use the pattern of writing all the functions code within the framework of a try/catch/finally lattice. Within finally perform the destruction code.

Instead of the C++ style of writing object classes with unspecified lifetimes, and then specifying the lifetime by arbitrary scopes and the implicit call to ~() at scope end (~() is destructor in C++), in this javascript pattern the object is the function, the scope is exactly the function scope, and the destructor is the finally block.

If you are now thinking this pattern is inherently flawed because try/catch/finally doesn't encompass asynchronous execution which is essential to javascript, then you are correct. Fortunately, since 2018 the asynchronous programming helper object Promise has had a prototype function finally added to the already existing resolve and catch prototype functions. That means that that asynchronous scopes requiring destructors can be written with a Promise object, using finally as the destructor. Furthermore you can use try/catch/finally in an async function calling Promises with or without await, but must be aware that Promises called without await will be execute asynchronously outside the scope and so handle the desctructor code in a final then.

In the following code PromiseA and PromiseB are some legacy API level promises which don't have finally function arguments specified. PromiseC DOES have a finally argument defined.

async function afunc(a,b){
    try {
        function resolveB(r){ ... }
        function catchB(e){ ... }
        function cleanupB(){ ... }
        function resolveC(r){ ... }
        function catchC(e){ ... }
        function cleanupC(){ ... }
        ...
        // PromiseA preced by await sp will finish before finally block.  
        // If no rush then safe to handle PromiseA cleanup in finally block 
        var x = await PromiseA(a);
        // PromiseB,PromiseC not preceded by await - will execute asynchronously
        // so might finish after finally block so we must provide 
        // explicit cleanup (if necessary)
        PromiseB(b).then(resolveB,catchB).then(cleanupB,cleanupB);
        PromiseC(c).then(resolveC,catchC,cleanupC);
    }
    catch(e) { ... }
    finally { /* scope destructor/cleanup code here */ }
}

I am not advocating that every object in javascript be written as a function. Instead, consider the case where you have a scope identified which really 'wants' a destructor to be called at its end of life. Formulate that scope as a function object, using the pattern's finally block (or finally function in the case of an asynchronous scope) as the destructor. It is quite like likely that formulating that functional object obviated the need for a non-function class which would otherwise have been written - no extra code was required, aligning scope and class might even be cleaner.

Note: As others have written, we should not confuse destructors and garbage collection. As it happens C++ destructors are often or mainly concerned with manual garbage collection, but not exclusively so. Javascript has no need for manual garbage collection, but asynchronous scope end-of-life is often a place for (de)registering event listeners, etc..

I run it like this -

created > startOfDay(-0d)

It gives me all issues created today. When you change -0d to -1d, it will give you all issues created yesterday and today.

public static void main(String[] args) {
    @SuppressWarnings("serial")
    List<Object> lst = new ArrayList<Object>() {
        @Override
        public boolean add(Object e) {
            if(!contains(e))
            return super.add(e);
            else
            return false;
        }
    };
    lst.add("ABC");
    lst.add("ABC");
    lst.add("ABCD");
    lst.add("ABCD");
    lst.add("ABCE");
    System.out.println(lst);

}

This is the better way

Alexandru Bantiuc's answer worked well for me to stop the build, but my executors were still showing up as busy. I was able clear the busy executor status using the following

server_name_pattern = /your-servers-[1-5]/
jenkins.model.Jenkins.instance.getComputers().each { computer ->
  if (computer.getName().find(server_name_pattern)) {
    println computer.getName()
    execList = computer.getExecutors()      
    for( exec in execList ) {
      busyState = exec.isBusy() ? ' busy' : ' idle'
      println '--' + exec.getDisplayName() + busyState
      if (exec.isBusy()) {
        exec.interrupt()
      }
    }
  }
}

Very easy code. You keep appending the path each time you discover a node.

graph = {
         'A': set(['B', 'C']),
         'B': set(['A', 'D', 'E']),
         'C': set(['A', 'F']),
         'D': set(['B']),
         'E': set(['B', 'F']),
         'F': set(['C', 'E'])
         }
def retunShortestPath(graph, start, end):

    queue = [(start,[start])]
    visited = set()

    while queue:
        vertex, path = queue.pop(0)
        visited.add(vertex)
        for node in graph[vertex]:
            if node == end:
                return path + [end]
            else:
                if node not in visited:
                    visited.add(node)
                    queue.append((node, path + [node]))

Another approach(Inside of $function to asure that the each is executed on document ready):

var ids = [1,2];
$(function(){
  $('.checkbox-wrapper>input[type="checkbox"]').each(function(i,item){
    if(ids.indexOf($(item).data('id')) > -1){
       $(item).prop("checked", "checked");
    }
  });
});

What is the n.fn.init[0], and why it is returned? Why are my two seemingly identical JQuery functions returning different things?

Answer: It seems that your elements are not in the DOM yet, when you are trying to find them. As @Rory McCrossan pointed out, the length:0 means that it doesn't find any element based on your search criteria.

About n.fn.init[0], lets look at the core of the Jquery Library:

var jQuery = function( selector, context ) {
   return new jQuery.fn.init( selector, context );
};

Looks familiar, right?, now in a minified version of jquery, this should looks like:

var n = function( selector, context ) {
   return new n.fn.init( selector, context );
};

So when you use a selector you are creating an instance of the jquery function; when found an element based on the selector criteria it returns the matched elements; when the criteria does not match anything it returns the prototype object of the function.

You can use the .not() method or :not() selector

Code based on your example:

$("ul#list li").not(".active") // not method
$("ul#list li:not(.active)")   // not selector

Try using this:

for k in range(1,c+1,2):

You may want to update you .bashrc and .bash_profile files with aliases to recognize the command you are entering.

.bashrc and .bash_profile files are hidden files probably located on your C: drive where you save your program files.

git stash apply n

works as of git version 2.11

Original answer, possibly helping to debug issues with the older syntax involving shell escapes:

As pointed out previously, the curly braces may require escaping or quoting depending on your OS, shell, etc.

See "stash@{1} is ambiguous?" for some detailed hints of what may be going wrong, and how to work around it in various shells and platforms.

        scope.removeEmptyDetails(details);
        expect(details.length).toEqual(3);

scope.removeEmptyDetails = function(details){
            _.remove(details, function(detail){
                return (_.isEmpty(detail.reference) && _.isEmpty(detail.description) && _.isEmpty(detail.price));
            });
        };

If a pipeline is too complicated to wrap in $(...), consider writing a function. Any local variables available at the time of definition will be accessible.

function getHash {
  genhash --use-ssl -s $IP -p 443 --url $URL | grep MD5 | grep -c $MD5
}
hash=$(getHash)
