Add a CommandName attribute, and optionally a CommandArgument attribute, to your LinkButton control. Then set the OnCommand attribute to the name of your Command event handler.

<asp:LinkButton ID="ENameLinkBtn" runat="server" CommandName="MyValueGoesHere" CommandArgument="OtherValueHere" 
          style="font-weight: 700; font-size: 8pt;" OnCommand="ENameLinkBtn_Command" ><%# Eval("EName") %></asp:LinkButton>

<asp:Label id="Label1" runat="server"/>

Then it will be available when in your handler:

protected void ENameLinkBtn_Command (object sender, CommandEventArgs e)
{
   Label1.Text = "You chose: " + e.CommandName + " Item " + e.CommandArgument;
}

This can be done very easily using a PostBackUrl and a regular button.

<asp:Button ID="Button1" runat="server" Text="Name of web location" PostBackUrl="web address" />

On Ubuntu and Debian systems, there are several steps needed:

1. In server.xml, change the line <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/> to have port="80".

2. Install the recommended (not required) authbind package, with a command like:

   sudo apt-get install authbind

3. Enable authbind in the server.xml file (in either /etc/tomcat6 or /etc/tomcat7) by uncommenting and setting the line like:

   AUTHBIND=yes

All three steps are needed.

• Integration testing: Integration testing is the integrate another element
• Smoke testing: Smoke testing is also known as build version testing. Smoke testing is the initial testing process exercised to check whether the software under test is ready/stable for further testing.
• Regression testing: Regression testing is repeated testing. Whether new software is effected in another module or not.
• Unit testing: It is a white box testing. Only developers involve in it

ButterKnife is probably the best solution for the clutter problem. It uses annotation processors to generate the so called "old method" boilerplate code.

But the onClick method can still be used, with a custom inflator.

How to use

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup cnt, Bundle state) {
    inflater = FragmentInflatorFactory.inflatorFor(inflater, this);
    return inflater.inflate(R.layout.fragment_main, cnt, false);
}

Implementation

public class FragmentInflatorFactory implements LayoutInflater.Factory {

    private static final int[] sWantedAttrs = { android.R.attr.onClick };

    private static final Method sOnCreateViewMethod;
    static {
        // We could duplicate its functionallity.. or just ignore its a protected method.
        try {
            Method method = LayoutInflater.class.getDeclaredMethod(
                    "onCreateView", String.class, AttributeSet.class);
            method.setAccessible(true);
            sOnCreateViewMethod = method;
        } catch (NoSuchMethodException e) {
            // Public API: Should not happen.
            throw new RuntimeException(e);
        }
    }

    private final LayoutInflater mInflator;
    private final Object mFragment;

    public FragmentInflatorFactory(LayoutInflater delegate, Object fragment) {
        if (delegate == null || fragment == null) {
            throw new NullPointerException();
        }
        mInflator = delegate;
        mFragment = fragment;
    }

    public static LayoutInflater inflatorFor(LayoutInflater original, Object fragment) {
        LayoutInflater inflator = original.cloneInContext(original.getContext());
        FragmentInflatorFactory factory = new FragmentInflatorFactory(inflator, fragment);
        inflator.setFactory(factory);
        return inflator;
    }

    @Override
    public View onCreateView(String name, Context context, AttributeSet attrs) {
        if ("fragment".equals(name)) {
            // Let the Activity ("private factory") handle it
            return null;
        }

        View view = null;

I'm afraid that the first of those command lines unconditionally deleted from the working copy all the files that are in git's staging area. The second one unstaged all the files that were tracked but have now been deleted. Unfortunately this means that you will have lost any uncommitted modifications to those files.

If you want to get your working copy and index back to how they were at the last commit, you can (carefully) use the following command:

git reset --hard

I say "carefully" since git reset --hard will obliterate uncommitted changes in your working copy and index. However, in this situation it sounds as if you just want to go back to the state at your last commit, and the uncommitted changes have been lost anyway.

Update: it sounds from your comments on Amber's answer that you haven't yet created any commits (since HEAD cannot be resolved), so this won't help, I'm afraid.

As for how those pipes work: git ls-files -z and git diff --name-only --diff-filter=D -z both output a list of file names separated with the byte 0. (This is useful, since, unlike newlines, 0 bytes are guaranteed not to occur in filenames on Unix-like systems.) The program xargs essentially builds command lines from its standard input, by default by taking lines from standard input and adding them to the end of the command line. The -0 option says to expect standard input to by separated by 0 bytes. xargs may invoke the command several times to use up all the parameters from standard input, making sure that the command line never becomes too long.

As a simple example, if you have a file called test.txt, with the following contents:

hello
goodbye
hello again

... then the command xargs echo whatever < test.txt will invoke the command:

echo whatever hello goodbye hello again

You can use git config status.showUntrackedFiles no and all untracked files will be hidden from you. See man git-config for details.

thanks to all
I use this version and say why (because I misses those explanations at the begining, so I try to help the next reader if he is as dull as me ...)

Remark : I wanted an efficient solution, so :

• only one regexp compilation (if needed)
• only one string scan for each string
• an efficient way to find the translated characters etc ...

My version is :
(there is no new technical trick inside it, only some selected ones + explanations why)

makeSortString = (function() {
    var translate_re = /[¹²³áàâãäåaaaÀÁÂÃÄÅAAAÆccç©CCÇÐÐèéê?ëeeeeeÈÊË?EEEEE€gGiìíîïìiiiÌÍÎÏ?ÌIIIlLnnñNNÑòóôõöoooøÒÓÔÕÖOOOØŒr®Ršs?ߊS?ùúûüuuuuÙÚÛÜUUUUýÿÝŸžzzŽZZ]/g;
    var translate = {
"¹":"1","²":"2","³":"3","á":"a","à":"a","â":"a","ã":"a","ä":"a","å":"a","a":"a","a":"a","a":"a","À":"a","Á":"a","Â":"a","Ã":"a","Ä":"a","Å":"a","A":"a","A":"a",
"A":"a","Æ":"a","c":"c","c":"c","ç":"c","©":"c","C":"c","C":"c","Ç":"c","Ð":"d","Ð":"d","è":"e","é":"e","ê":"e","?":"e","ë":"e","e":"e","e":"e","e":"e","e":"e",
"e":"e","È":"e","Ê":"e","Ë":"e","?":"e","E":"e","E":"e","E":"e","E":"e","E":"e","€":"e","g":"g","G":"g","i":"i","ì":"i","í":"i","î":"i","ï":"i","ì":"i","i":"i",
"i":"i","i":"i","Ì":"i","Í":"i","Î":"i","Ï":"i","?":"i","Ì":"i","I":"i","I":"i","I":"i","l":"l","L":"l","n":"n","n":"n","ñ":"n","N":"n","N":"n","Ñ":"n","ò":"o",
"ó":"o","ô":"o","õ":"o","ö":"o","o":"o","o":"o","o":"o","ø":"o","Ò":"o","Ó":"o","Ô":"o","Õ":"o","Ö":"o","O":"o","O":"o","O":"o","Ø":"o","Œ":"o","r":"r","®":"r",
"R":"r","š":"s","s":"s","?":"s","ß":"s","Š":"s","S":"s","?":"s","ù":"u","ú":"u","û":"u","ü":"u","u":"u","u":"u","u":"u","u":"u","Ù":"u","Ú":"u","Û":"u","Ü":"u",
"U":"u","U":"u","U":"u","U":"u","ý":"y","ÿ":"y","Ý":"y","Ÿ":"y","ž":"z","z":"z","z":"z","Ž":"z","Z":"z","Z":"z"
    };
    return function(s) {
        return(s.replace(translate_re, function(match){return translate[match];}) );
    }
})();

and I use it this way :

var without_accents = makeSortString("wïthêüÄTrèsBïgüeAk100t");
// I let you guess the result,
// no I was kidding you : I give you the result : witheuatresbigueak100t

Comments :

• Tthe instruction inside it is done once (after, makeSortString != undefined)
• function(){...} is stored once in makeSortString, so the "big" translate_re and translate objects are stored once
• When you call makeSortString('something') it call directly the inside function which calls only s.replace(...) : it is efficient
• s.replace uses regexp (the special syntax of var translate_re= .... is in fact equivalent to var translate_re = new RegExp("[¹....Z]","g"); but the compilation of the regexp is done once for all, and the scan of the s String is done one for a call of the function (not for every character as it would be in a loop)
• For each character found s.replace calls function(match) where parameter match contains the character found, and it call the corresponding translated character (translate[match])
• Translate[match] is probably efficient too as the javascript translate object is probably implemented by javascript with a hashtab or something equivalent and allow the program to find the translated character almost directly and not for instance through a loop on a array of all characters to find the right one (which would be awfully unefficient).

A simple solution is to assign color for each class. This way, we can control how each color is for each class. For example:

arr1 = [1, 2, 3, 4, 5]
arr2 = [2, 3, 3, 4, 4]
labl = [0, 1, 1, 0, 0]
color= ['red' if l == 0 else 'green' for l in labl]
plt.scatter(arr1, arr2, color=color)

Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".

Two options:

Firstly, you can escape it using a backslash -- \(

Alternatively, since it's a single character, you can put it in a character class, where it doesn't need to be escaped -- [(]

If display: none; doesn't work, how about setting height: 0; instead? In conjunction with a negative margin (equal to, or greater than, the height of the top and bottom borders, if any) to further remove the element? I don't imagine that position: absolute; top: 0; left: -4000px; would work, but it might be worth a try.

For my part, using display: none works fine.

Only this helped me:

To use the web administration gui you have to add the gui role :

<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="manager"/>
<role rolename="manager-gui"/>

<user username="name" password="pwd" roles="admin,admin-gui,manager,manager-gui"/>

Both questions are answered in git status.

To unstage adding a new file use git rm --cached filename.ext

# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#   new file:   test

To unstage deleting a file use git reset HEAD filename.ext

# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   deleted:    test

In the other hand, git checkout -- never unstage, it just discards non-staged changes.

You can simply add these lines of codes here to hide a row,

Either you can write border:0 or border-style:hidden; border: none or it will happen the same thing

There is even easier way how to work with JSONP using jQuery

$.getJSON("http://example.com/something.json?callback=?", function(result){
   //response data are now in the result variable
   alert(result);
});

The ? on the end of the URL tells jQuery that it is a JSONP request instead of JSON. jQuery registers and calls the callback function automatically.

For more detail refer to the jQuery.getJSON documentation.

Make sure the scp command is available on both sides - both on the client and on the server.

If this is Fedora or Red Hat Enterprise Linux and clones (CentOS), make sure this package is installed:

    yum -y install openssh-clients

If you work with Debian or Ubuntu and clones, install this package:

    apt-get install openssh-client

Again, you need to do this both on the server and the client, otherwise you can encounter "weird" error messages on your client: scp: command not found or similar although you have it locally. This already confused thousands of people, I guess :)

One important thing I missed from the tutorials for a while (stolen from http://www.tramontana.co.hu/wix/lesson4.php) which resulted in the "Another version of this product is already installed" errors:

*Small updates mean small changes to one or a few files where the change doesn't warrant changing the product version (major.minor.build). You don't have to change the Product GUID, either. Note that you always have to change the Package GUID when you create a new .msi file that is different from the previous ones in any respect. The Installer keeps track of your installed programs and finds them when the user wants to change or remove the installation using these GUIDs. Using the same GUID for different packages will confuse the Installer.

Minor upgrades denote changes where the product version will already change. Modify the Version attribute of the Product tag. The product will remain the same, so you don't need to change the Product GUID but, of course, get a new Package GUID.

Major upgrades denote significant changes like going from one full version to another. Change everything: Version attribute, Product and Package GUIDs.

MaxLength is used for the Entity Framework to decide how large to make a string value field when it creates the database.

From MSDN:

Specifies the maximum length of array or string data allowed in a property.

StringLength is a data annotation that will be used for validation of user input.

From MSDN:

Specifies the minimum and maximum length of characters that are allowed in a data field.

Non Customized

Use [String Length]

[RegularExpression(@"^.{3,}$", ErrorMessage = "Minimum 3 characters required")]
[Required(ErrorMessage = "Required")]
[StringLength(30, MinimumLength = 3, ErrorMessage = "Maximum 30 characters")]

30 is the Max Length
Minimum length = 3

Customized StringLengthAttribute Class

public class MyStringLengthAttribute : StringLengthAttribute
{
    public MyStringLengthAttribute(int maximumLength)
        : base(maximumLength)
    {
    }

    public override bool IsValid(object value)
    {
        string val = Convert.ToString(value);
        if (val.Length < base.MinimumLength)
            base.ErrorMessage = "Minimum length should be 3";
        if (val.Length > base.MaximumLength)
            base.ErrorMessage = "Maximum length should be 6";
        return base.IsValid(value);
    }
}

public class MyViewModel
{
    [MyStringLength(6, MinimumLength = 3)]
    public String MyProperty { get; set; }
}

This works for me if you have config and the private key file in the /Jenkins/.ssh/ you need to chown (change owner) for these 2 files then restart jenkins in order for the jenkins instance to read these 2 files.

Install firebug: http://getfirebug.com/logging . You can use its console to test Javascript code. Google Chrome comes with Web Inspector in which you can do the same. IE and Safari also have Web Developer tools in which you can test Javascript.

I am using TypeScript version 3.6 and I can do like this:

let templateStr = 'This is an {0} for {1} purpose';

const finalStr = templateStr.format('example', 'format'); // This is an example for format purpose

Use fileReader.readAsDataURL( fileObject ), this will encode it to base64, which you can safely upload to your server.

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

Well I found this way :

Delete all files under the .m2 repository folder and rebuild the project.

Static variable in a header file:

say 'common.h' has

static int zzz;

This variable 'zzz' has internal linkage (This same variable can not be accessed in other translation units). Each translation unit which includes 'common.h' has it's own unique object of name 'zzz'.

Static variable in a class:

Static variable in a class is not a part of the subobject of the class. There is only one copy of a static data member shared by all the objects of the class.

$9.4.2/6 - "Static data members of a class in namespace scope have external linkage (3.5).A local class shall not have static data members."

So let's say 'myclass.h' has

struct myclass{
   static int zzz;        // this is only a declaration
};

and myclass.cpp has

#include "myclass.h"

int myclass::zzz = 0           // this is a definition, 
                               // should be done once and only once

and "hisclass.cpp" has

#include "myclass.h"

void f(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

and "ourclass.cpp" has

#include "myclass.h"
void g(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

So, class static members are not limited to only 2 translation units. They need to be defined only once in any one of the translation units.

Note: usage of 'static' to declare file scope variable is deprecated and unnamed namespace is a superior alternate

Use LAST_INSERT_ID() from your SQL query.

Or

You can also use mysql_insert_id() to get it using PHP.

dtList  = dtList.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList()

I assumed empty string and whitespace are like null. If not you can use IsNullOrEmpty (allow whitespace), or s != null

This is what I use to display images from blob:

echo '<img src="data:image/jpeg;base64,'.base64_encode($image->load()) .'" />';

At compile time the number "600851475143" is represented in 32-bit integer, try long literal instead at the end of your number to get over from this problem.

too late to answer but here is my approach since no one mentioned this here:
why note a client side solution ?
a javascript implementation to store the mac in a cookie (you can encrypt it before that)
then each request must include that cookie name, else it will be rejected.
to make this even more fun you can make a server side verification
from the mac address you get the manifacturer (there are plenty of free APIs for this)
then compare it with the user_agent value to see if there was some sort of manipulation:
a mac address of HP + a user agent of Safari = reject request.

The long answer is that there are lot of variations how a text is encoded inside PDF and that it may require to decoded PDF string itself, then may need to map with CMAP, then may need to analyze distance between words and letters etc.

In case the PDF is damaged (i.e. displaying the correct text but when copying it gives garbage) and you really need to extract text, then you may want to consider converting PDF into image (using ImageMagik) and then use Tesseract to get text from image using OCR.

Al types of solution are supplied. So I want to try for a different solution. Simply it will be more easy if you add a id attribute in your input fields.

<input type="text" name="textField" id="textField"/>
<input type="submit" value="send" id="submitYesNo"/>

Now here is your jQuery

$("#textField").change(function(){
  if($("#textField").val()=="")
    $("#submitYesNo").prop('disabled', true)
  else
    $("#submitYesNo").prop('disabled', false)
});

The problem you have is caused that you use the same ArrayList NodeList over all iterations in main for loop. Each iterations NodeList is enlarged by new elements.

1. After first loop, NodeList has 5 elements (PropertyStart,a,b,c,PropertyEnd) and list has 1 element (NodeList: (PropertyStart,a,b,c,PropertyEnd))

2. After second loop NodeList has 10 elements (PropertyStart,a,b,c,PropertyEnd,PropertyStart,d,e,f,PropertyEnd) and list has 2 elements (NodeList (with 10 elements), NodeList (with 10 elements))

To get you expectations you must replace

NodeList.addAll(nodes);
list.add(NodeList)

by

List childrenList = new ArrayList(nodes);
list.add(childrenList);

PS. Your code is not readable, keep Java code conventions to have readble code. For example is hard to recognize if NodeList is a class or object

try using this:

sqrt(sum((x1-x2)^2))

As indicated in Elasticsearch reference for snapshot module,

The rename_pattern and rename_replacement options can be also used to rename index on restore using regular expression

if a device has an SD card, you use:

Environment.getExternalStorageState() 

if you don't have an SD card, you use:

Environment.getDataDirectory()

if there is no SD card, you can create your own directory on the device locally.

    //if there is no SD card, create new directory objects to make directory on device
        if (Environment.getExternalStorageState() == null) {
                        //create new file directory object
            directory = new File(Environment.getDataDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(Environment.getDataDirectory()
                    + "/Robotium-Screenshots/");
            /*
             * this checks to see if there are any previous test photo files
             * if there are any photos, they are deleted for the sake of
             * memory
             */
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length != 0) {
                    for (int ii = 0; ii <= dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                }
            }
            // if no directory exists, create new directory
            if (!directory.exists()) {
                directory.mkdir();
            }

            // if phone DOES have sd card
        } else if (Environment.getExternalStorageState() != null) {
            // search for directory on SD card
            directory = new File(Environment.getExternalStorageDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(
                    Environment.getExternalStorageDirectory()
                            + "/Robotium-Screenshots/");
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length > 0) {
                    for (int ii = 0; ii < dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                    dirFiles = null;
                }
            }
            // if no directory exists, create new directory to store test
            // results
            if (!directory.exists()) {
                directory.mkdir();
            }
        }// end of SD card checking

add permissions on your manifest.xml

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

Happy coding..

Im not very familiar with the Android sdk, but it seems that the android-sdk comes with the BouncyCastle provider already added to the security.

What you will have to do in the PC environment is just add it manually,

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

if you have access to the policy file, just add an entry like:

security.provider.5=org.bouncycastle.jce.provider.BouncyCastleProvider 

Notice the .5 it is equal to a sequential number of the already added providers.

I accidentally installed 'serial' (sudo python -m pip install serial) instead of 'pySerial' (sudo python -m pip install pyserial), which lead to the same error.

If the previously mentioned solutions did not work for you, double check if you installed the correct library.

My solution works perfectly giving the exact value for each scroll direction. distanceFromFirstCellToTop contains the exact distance from the first cell to the top of the parent View. I save this value in previousDistanceFromFirstCellToTop and as I scroll I compare it with the new value. If it's lower then I scrolled up, else, I scrolled down.

private int previousDistanceFromFirstCellToTop;

listview.setOnScrollListener(new OnScrollListener() {

    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {

    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
        View firstCell = listview.getChildAt(0);
        int distanceFromFirstCellToTop = listview.getFirstVisiblePosition() * firstCell.getHeight() - firstCell.getTop();

        if(distanceFromFirstCellToTop < previousDistanceFromFirstCellToTop)
        {
           //Scroll Up
        }
        else if(distanceFromFirstCellToTop  > previousDistanceFromFirstCellToTop)
        {
           //Scroll Down
        }
        previousDistanceFromFirstCellToTop = distanceFromFirstCellToTop;
    }
});

For Xamarin developers, the solution is the following:

Note: don't forget to run on UI thread

listView.Scroll += (o, e) =>
{
    View firstCell = listView.GetChildAt(0);
    int distanceFromFirstCellToTop = listView.FirstVisiblePosition * firstCell.Height - firstCell.Top;

    if (distanceFromFirstCellToTop < previousDistanceFromFirstCellToTop)
    {
        //Scroll Up
    }
    else if (distanceFromFirstCellToTop > previousDistanceFromFirstCellToTop)
    {
        //Scroll Down
    }
    previousDistanceFromFirstCellToTop = distanceFromFirstCellToTop;
};

For Firebird:

Select FIRST 1 column from table ORDER BY RAND()

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

Spring has built-in support for this with an AbstractRequestLoggingFilter:

@Bean
public Filter loggingFilter(){
    final AbstractRequestLoggingFilter filter = new AbstractRequestLoggingFilter() {
        @Override
        protected void beforeRequest(final HttpServletRequest request, final String message) {

        }

        @Override
        protected void afterRequest(final HttpServletRequest request, final String message) {

        }
    };

    filter.setIncludePayload(true);
    filter.setIncludeQueryString(false);
    filter.setMaxPayloadLength(1000000);

    return filter;
}

Unfortunately you still won't be able to read the payload directly off the request, but the String message parameter will include the payload so you can grab it from there as follows:

String body = message.substring(message.indexOf("{"), message.lastIndexOf("]"));

First, you should define "doesn't work".
Second, I assume that your table field 'content' is varchar/text, so you need to enclose it in quotes. content = '{$content}'
And last but not least: use echo mysql_error() directly after a query to debug.

Try below Alphanumeric regex

"^[a-zA-Z0-9]*$"

^ - Start of string

[a-zA-Z0-9]* - multiple characters to include

$ - End of string

Kris, your version works great when needing to load the assembly from the actual DLL file (and if the DLL is there!), however, one will get a much unwanted error if the DLL is EMBEDDED (i.e., not a file but an embedded DLL).

The other thing is, if one uses a versioning scheme with something like "1.2012.0508.0101", when one gets the version string you'll actually get "1.2012.518.101"; note the missing zeros.

So, here's a few extra functions to get the version of a DLL (embedded or from the DLL file):

    public static System.Reflection.Assembly GetAssembly(string pAssemblyName)
    {
        System.Reflection.Assembly tMyAssembly = null;

        if (string.IsNullOrEmpty(pAssemblyName)) { return tMyAssembly; }
        tMyAssembly = GetAssemblyEmbedded(pAssemblyName);
        if (tMyAssembly == null) { GetAssemblyDLL(pAssemblyName); }

        return tMyAssembly;
    }//System.Reflection.Assembly GetAssemblyEmbedded(string pAssemblyDisplayName)


    public static System.Reflection.Assembly GetAssemblyEmbedded(string pAssemblyDisplayName)
    {
        System.Reflection.Assembly tMyAssembly = null;

        if(string.IsNullOrEmpty(pAssemblyDisplayName)) { return tMyAssembly; }
        try //try #a
        {
            tMyAssembly = System.Reflection.Assembly.Load(pAssemblyDisplayName);
        }// try #a
        catch (Exception ex)
        {
            string m = ex.Message;
        }// try #a
        return tMyAssembly;
    }//System.Reflection.Assembly GetAssemblyEmbedded(string pAssemblyDisplayName)


    public static System.Reflection.Assembly GetAssemblyDLL(string pAssemblyNameDLL)
    {
        System.Reflection.Assembly tMyAssembly = null;

        if (string.IsNullOrEmpty(pAssemblyNameDLL)) { return tMyAssembly; }
        try //try #a
        {
            if (!pAssemblyNameDLL.ToLower().EndsWith(".dll")) { pAssemblyNameDLL += ".dll"; }
            tMyAssembly = System.Reflection.Assembly.LoadFrom(pAssemblyNameDLL);
        }// try #a
        catch (Exception ex)
        {
            string m = ex.Message;
        }// try #a
        return tMyAssembly;
    }//System.Reflection.Assembly GetAssemblyFile(string pAssemblyNameDLL)


    public static string GetVersionStringFromAssembly(string pAssemblyDisplayName)
    {
        string tVersion = "Unknown";
        System.Reflection.Assembly tMyAssembly = null;

        tMyAssembly = GetAssembly(pAssemblyDisplayName);
        if (tMyAssembly == null) { return tVersion; }
        tVersion = GetVersionString(tMyAssembly.GetName().Version.ToString());
        return tVersion;
    }//string GetVersionStringFromAssemblyEmbedded(string pAssemblyDisplayName)


    public static string GetVersionString(Version pVersion)
    {
        string tVersion = "Unknown";
        if (pVersion == null) { return tVersion; }
        tVersion = GetVersionString(pVersion.ToString());
        return tVersion;
    }//string GetVersionString(Version pVersion)


    public static string GetVersionString(string pVersionString)
    {
        string tVersion = "Unknown";
        string[] aVersion;

        if (string.IsNullOrEmpty(pVersionString)) { return tVersion; }
        aVersion = pVersionString.Split('.');
        if (aVersion.Length > 0) { tVersion = aVersion[0]; }
        if (aVersion.Length > 1) { tVersion += "." + aVersion[1]; }
        if (aVersion.Length > 2) { tVersion += "." + aVersion[2].PadLeft(4, '0'); }
        if (aVersion.Length > 3) { tVersion += "." + aVersion[3].PadLeft(4, '0'); }

        return tVersion;
    }//string GetVersionString(Version pVersion)


    public static string GetVersionStringFromAssemblyEmbedded(string pAssemblyDisplayName)
    {
        string tVersion = "Unknown";
        System.Reflection.Assembly tMyAssembly = null;

        tMyAssembly = GetAssemblyEmbedded(pAssemblyDisplayName);
        if (tMyAssembly == null) { return tVersion; }
        tVersion = GetVersionString(tMyAssembly.GetName().Version.ToString());
        return tVersion;
    }//string GetVersionStringFromAssemblyEmbedded(string pAssemblyDisplayName)


    public static string GetVersionStringFromAssemblyDLL(string pAssemblyDisplayName)
    {
        string tVersion = "Unknown";
        System.Reflection.Assembly tMyAssembly = null;

        tMyAssembly = GetAssemblyDLL(pAssemblyDisplayName);
        if (tMyAssembly == null) { return tVersion; }

No, it is not okay to put a link element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):

“This element defines a link. Unlike A, it may only appear in the HEAD section of a document, although it may appear any number of times.”

With Apache Commons Library, you can simply use Stringutils.replaceEach:

public static String replaceEach(String text,
                             String[] searchList,
                             String[] replacementList)

From the documentation:

Replaces all occurrences of Strings within another String.

A null reference passed to this method is a no-op, or if any "search string" or "string to replace" is null, that replace will be ignored. This will not repeat. For repeating replaces, call the overloaded method.

 StringUtils.replaceEach(null, *, *)        = null

  StringUtils.replaceEach("", *, *)          = ""

  StringUtils.replaceEach("aba", null, null) = "aba"

  StringUtils.replaceEach("aba", new String[0], null) = "aba"

  StringUtils.replaceEach("aba", null, new String[0]) = "aba"

  StringUtils.replaceEach("aba", new String[]{"a"}, null)  = "aba"

  StringUtils.replaceEach("aba", new String[]{"a"}, new String[]{""})  = "b"

  StringUtils.replaceEach("aba", new String[]{null}, new String[]{"a"})  = "aba"

  StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"w", "t"})  = "wcte"
  (example of how it does not repeat)

StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"d", "t"})  = "dcte"

I know this question has been answered but the answers i found here didn't work for my scenario ( or for Windows ).

I am using windows 10 laptop with PHP 7.2 in Xampp v3.2.4.

$command = 'php Cron.php send_email "'. $id .'"';
if ( substr(php_uname(), 0, 7) == "Windows" )
{
    //windows
    pclose(popen("start /B " . $command . " 1> temp/update_log 2>&1 &", "r"));
}
else
{
    //linux
    shell_exec( $command . " > /dev/null 2>&1 &" );
}

This worked perfectly for me.

I hope it will help someone with windows. Cheers.

Try this (using default keyword)

 bool foo = default(bool); if (foo) { } 

You can try this also:

private void Page_Loaded_1(object sender, RoutedEventArgs e)
    {
        Uri iconUri = new Uri(@"C:\Apps\R&D\WPFNavigation\WPFNavigation\Images\airport.ico", UriKind.RelativeOrAbsolute);
        (this.Parent as Window).Icon = BitmapFrame.Create(iconUri);
    }

Another simple way using concat:

this.setState({
  arr: this.state.arr.concat('new value')
})

Just replace from bottom and add this

tv.setLayoutParams(new ViewGroup.LayoutParams(
    ViewGroup.LayoutParams.WRAP_CONTENT,
    ViewGroup.LayoutParams.WRAP_CONTENT));

before

llview.addView(tv);

Simplest way to read a file in Swift > 4.0

        }
        catch(_){print("error")}
    }

Since Oracle inserted some md5hash in their download links, one cannot automatically assemble a download link for command line.

So I tinkered some nasty bash command line to get the latest jdk download link, download it and directly install via rpm. For all who are interested:

wget -q http://www.oracle.com/technetwork/java/javase/downloads/index.html -O ./index.html && grep -Eoi ']+>' index.html | grep -Eoi '/technetwork/java/javase/downloads/jdk8-downloads-[0-9]+.html' | (head -n 1) | awk '{print "http://www.oracle.com"$1}' | xargs wget --no-cookies --header "Cookie: gpw_e24=xxx; oraclelicense=accept-securebackup-cookie;" -O index.html -q && grep -Eoi '"filepath":"[^"]+jdk-8u[0-9]+-linux-x64.rpm"' index.html | grep -Eoi 'http:[^"]+' | xargs wget --no-cookies --header "Cookie: gpw_e24=xxx; oraclelicense=accept-securebackup-cookie;" -q -O ./jdk8.rpm && sudo rpm -i ./jdk8.rpm

The bold part should be replaced by the package of your liking.

$('.date-picker').datepicker({
                    autoclose : true,

This outputs:

I got the same error using:

simply you can use

$("#yourtextboxid").attr("placeholder", "variable");

where, if variable is string then you can use like above, if it is variable replace it with the name like "variable" with out double quotes.

eg: $("#youtextboxid").attr("placeholder", variable); it will work.

console.log(total / grades.length)

It is a reference to the current file name. In the file foo.rb, __FILE__ would be interpreted as "foo.rb".

Edit: Ruby 1.9.2 and 1.9.3 appear to behave a little differently from what Luke Bayes said in his comment. With these files:

# test.rb
puts __FILE__
require './dir2/test.rb'

# dir2/test.rb
puts __FILE__

Running ruby test.rb will output

test.rb
/full/path/to/dir2/test.rb

Try this: Adding users to MySQL

You need grant privileges to the user if you want external acess to database(ie. web pages).

In my experience, I often encounter the following situations;

1. If you work in a corporate company, contact the network and security team. Because in requests made to external services, it may be necessary to give permission for the relevant endpoint.

2. Another issue is that the SSL certificate may have expired on the server where your application is running.

Warning: This solution is deprecated since Angular 5.5, please refer to Trent's answer below

=====================

Yes, you need to import the operator:

import 'rxjs/add/operator/catch';

Or import Observable this way:

import {Observable} from 'rxjs/Rx';

But in this case, you import all operators.

See this question for more details:

• Angular HTTP GET with TypeScript error http.get(...).map is not a function in [null]

My English is not good so I'll just write a simple example here.

    double a = 0.02;
    double b = 0.03;
    double c = b - a;
    System.out.println(c);

    BigDecimal _a = new BigDecimal("0.02");
    BigDecimal _b = new BigDecimal("0.03");
    BigDecimal _c = _b.subtract(_a);
    System.out.println(_c);

Program output:

0.009999999999999998
0.01

Somebody still want to use double? ;)

This thread was helpful in finding the solution in my particular case (bootstrap 3)

@media (max-width: 767px) {
  .container-fluid, .row {
    padding:0px;
  }
  .navbar-header {
    margin:0px;
  }
}

First, I strongly recommend that you rename your variable list to something else. list is the name of the built-in list constructor, and you're hiding its normal function. I will rename list to a in the following.

Python names are references that are bound to objects. That means that unless you create more than one list, whenever you use a it's referring to the same actual list object as last time. So when you call

listoflists.append((a, a[0]))

you can later change a and it changes what the first element of that tuple points to. This does not happen with a[0] because the object (which is an integer) pointed to by a[0] doesn't change (although a[0] points to different objects over the run of your code).

You can create a copy of the whole list a using the list constructor:

listoflists.append((list(a), a[0]))

Or, you can use the slice notation to make a copy:

listoflists.append((a[:], a[0]))

apc_clear_cache() only works on the same php SAPI that you want you cache cleared. If you have PHP-FPM and want to clear apc cache, you have do do it through one of php scripts, NOT the command line, because the two caches are separated.

I have written CacheTool, a command line tool that solves exactly this problem and with one command you can clear your PHP-FPM APC cache from the commandline (it connects to php-fpm for you, and executes apc functions)

It also works for opcache.

See how it works here: http://gordalina.github.io/cachetool/

The advantage of IEnumerable is deferred execution (usually with databases). The query will not get executed until you actually loop through the data. It's a query waiting until it's needed (aka lazy loading).

If you call ToList, the query will be executed, or "materialized" as I like to say.

There are pros and cons to both. If you call ToList, you may remove some mystery as to when the query gets executed. If you stick to IEnumerable, you get the advantage that the program doesn't do any work until it's actually required.

I encountered the same problem in college having installed Linux Mint for the main project of my final year, the third solution below worked for me.

When encountering this error please note before the error it may say you are missing a package or header file — you should find those and install them and verify if it works (e.g. ssl ? libssl).

For Python 2.x use:

$ sudo apt-get install python-dev

For Python 2.7 use:

$ sudo apt-get install libffi-dev

For Python 3.x use:

$ sudo apt-get install python3-dev

or for a specific version of Python 3, replace x with the minor version in

$ sudo apt-get install python3.x-dev

The best is QSpinBox.

And for a double value use QDoubleSpinBox.

QSpinBox myInt;
myInt.setMinimum(-5);
myInt.setMaximum(5);
myInt.setSingleStep(1);// Will increment the current value with 1 (if you use up arrow key) (if you use down arrow key => -1)
myInt.setValue(2);// Default/begining value
myInt.value();// Get the current value
//connect(&myInt, SIGNAL(valueChanged(int)), this, SLOT(myValueChanged(int)));

I hate answering my own question, but @Matt Bodily put me on the right track.

The @Html.Action method actually invokes a controller and renders the view, so that wouldn't work to create a snippet of HTML in my case, as this was causing a recursive function call resulting in a StackOverflowException. The @Url.Action(action, controller, { area = "abc" }) does indeed return the URL, but I finally discovered an overload of Html.ActionLink that provided a better solution for my case:

@Html.ActionLink("Admin", "Index", "Home", new { area = "Admin" }, null)

Note: , null is significant in this case, to match the right signature.

Documentation: @Html.ActionLink (LinkExtensions.ActionLink)

Documentation for this particular overload:

LinkExtensions.ActionLink(Controller, Action, Text, RouteArgs, HtmlAttributes)

It's been difficult to find documentation for these helpers. I tend to search for "Html.ActionLink" when I probably should have searched for "LinkExtensions.ActionLink", if that helps anyone in the future.

Still marking Matt's response as the answer.

Edit: Found yet another HTML helper to solve this:

@Html.RouteLink("Admin", new { action = "Index", controller = "Home", area = "Admin" })

If you are using MS Excel 2003 then go to view->Tool bar->Pivot Table From this tool bar we can do refresh by clicking ! this symbol.

You may want to use:

SELECT Name, 'Unpaid' AS Status FROM table;

The SELECT clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:

SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ] 
<select_list> 

Where the expression can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.

The best place to start looking is http://api.jquery.com/category/selectors/

This will give you a good set of examples.

Ultamatly the selecting of elements in the DOM is achived using CSS selectors so if you think about getting an element by id you will want to use $('#elementId'), if you want all the input tags use $('input') and finaly the part i think you'll want if you want all input tags with a type of checkbox use $('input, [type=checkbox])

Note: You'll find most of the values you want are on attributes so the css selector for attributes is: [attributeName=value]

Just because you asked for the dropdown as aposed to a listbox try the following:

$('select, [size]).each(function(){
  var selectedItem = $('select, [select]', this).first();
});

The code was from memory so please accound for small errors

Build a list from the columns and remove the column you don't want to calculate the Z score for:

cols.remove('ID')
df[cols]

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

Here is a solution using the javax.crypto library and the apache commons codec library for encoding and decoding in Base64 that I was looking for:

import java.security.spec.KeySpec;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import org.apache.commons.codec.binary.Base64;

public class TrippleDes {

    private static final String UNICODE_FORMAT = "UTF8";
    public static final String DESEDE_ENCRYPTION_SCHEME = "DESede";
    private KeySpec ks;
    private SecretKeyFactory skf;
    private Cipher cipher;
    byte[] arrayBytes;
    private String myEncryptionKey;
    private String myEncryptionScheme;
    SecretKey key;

    public TrippleDes() throws Exception {
        myEncryptionKey = "ThisIsSpartaThisIsSparta";
        myEncryptionScheme = DESEDE_ENCRYPTION_SCHEME;
        arrayBytes = myEncryptionKey.getBytes(UNICODE_FORMAT);
        ks = new DESedeKeySpec(arrayBytes);
        skf = SecretKeyFactory.getInstance(myEncryptionScheme);
        cipher = Cipher.getInstance(myEncryptionScheme);
        key = skf.generateSecret(ks);
    }


    public String encrypt(String unencryptedString) {
        String encryptedString = null;
        try {
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] plainText = unencryptedString.getBytes(UNICODE_FORMAT);
            byte[] encryptedText = cipher.doFinal(plainText);
            encryptedString = new String(Base64.encodeBase64(encryptedText));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return encryptedString;
    }


    public String decrypt(String encryptedString) {
        String decryptedText=null;
        try {
            cipher.init(Cipher.DECRYPT_MODE, key);
            byte[] encryptedText = Base64.decodeBase64(encryptedString);
            byte[] plainText = cipher.doFinal(encryptedText);
            decryptedText= new String(plainText);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return decryptedText;
    }


    public static void main(String args []) throws Exception
    {
        TrippleDes td= new TrippleDes();

        String target="imparator";
        String encrypted=td.encrypt(target);
        String decrypted=td.decrypt(encrypted);

        System.out.println("String To Encrypt: "+ target);
        System.out.println("Encrypted String:" + encrypted);
        System.out.println("Decrypted String:" + decrypted);

    }

}

Running the above program results with the following output:

String To Encrypt: imparator
Encrypted String:FdBNaYWfjpWN9eYghMpbRA==
Decrypted String:imparator

I was looking for this too. I've got a project that runs HWC, and I'd like to keep the web site out of the app tree, but I don't want to keep it in the debug (or release) directory. FWIW, the accepted solution (and this one as well) only identifies the directory the executable is running in.

To find that directory, I've been using

string startupPath = System.IO.Path.GetFullPath(".\\").

Try the following:

<a asp-controller="Users" asp-action="Index"></a>

(Valid for ASP.NET 5 and MVC 6)

Have you tried:

 <fragment
            android:name="de.androidbuch.activiti.task.TaskDetailsFragment"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />

If all you want is the file name without file extension

Dim fileNamesCol As New Collection
Dim MyFile As Variant  'Strings and primitive data types aren't allowed with collection

filePath = "c:\file directory" + "\"
MyFile = Dir$(filePath & "*.xlsx")
Do While MyFile <> ""
    fileNamesCol.Add (Replace(MyFile, ".xlsx", ""))
    MyFile = Dir$
Loop

To output to excel worksheet

Dim myWs As Worksheet: Set myWs = Sheets("SheetNameToDisplayTo")
Dim ic As Integer: ic = 1

For Each MyFile In fileNamesCol
    myWs.Range("A" & ic).Value = fileNamesCol(ic)
    ic = ic + 1
Next MyFile

Primarily based on the technique detailed here: https://wordmvp.com/FAQs/MacrosVBA/ReadFilesIntoArray.htm

Some frameworks are using this header to detect xhr requests e.g. grails spring security is using this header to identify xhr request and give either a json response or html response as response.

Most Ajax libraries (Prototype, JQuery, and Dojo as of v2.1) include an X-Requested-With header that indicates that the request was made by XMLHttpRequest instead of being triggered by clicking a regular hyperlink or form submit button.

Type hint are a recent addition to a dynamic language where for decades folks swore naming conventions as simple as Hungarian (object label with first letter b = Boolean, c = character, d = dictionary, i = integer, l = list, n = numeric, s = string, t= tuple) were not needed, too cumbersome, but now have decided that, oh wait ... it is way too much trouble to use the language (type()) to recognize objects, and our fancy IDEs need help doing anything that complicated, and that dynamically assigned object values make them completely useless anyhow, whereas a simple naming convention could have resolved all of it, for any developer, at a mere glance.

I figured it out!

After reading this blog post I realized that the placement of this line:

<script src="{% static "build/react.js" %}"></script>

was wrong. That line needs to be the last line in the <body> section, right before the </body> tag. Moving the line down solves the problem.

My explanation for this is that react was looking for the id in between the <head> tags, instead of in the <body> tags. Because of this it couldn't find the content id, and thus it wasn't a real DOM element.

andig is correct that a common reason for LayoutInflater ignoring your layout_params would be because a root was not specified. Many people think you can pass in null for root. This is acceptable for a few scenarios such as a dialog, where you don't have access to root at the time of creation. A good rule to follow, however, is that if you have root, give it to LayoutInflater.

I wrote an in-depth blog post about this that you can check out here:

https://www.bignerdranch.com/blog/understanding-androids-layoutinflater-inflate/

Check out the FileUtils class in Apache Commons - specifically iterateFiles:

Allows iteration over the files in given directory (and optionally its subdirectories).

I suppose one thing that may be concerning you is whether or not the entries could change, so that the 2 becomes a different number, for instance. You can put your mind at ease here, because in Python, integers are immutable, meaning they cannot change after they are created.

Not everything in Python is immutable, though. For example, lists are mutable---they can change after being created. So for example, if you had a list of lists

>>> a = [[1], [2], [3]]
>>> a[0].append(7)
>>> a
[[1, 7], [2], [3]]

Here, I changed the first entry of a (I added 7 to it). One could imagine shuffling things around, and getting unexpected things here if you are not careful (and indeed, this does happen to everyone when they start programming in Python in some way or another; just search this site for "modifying a list while looping through it" to see dozens of examples).

It's also worth pointing out that x = x + [a] and x.append(a) are not the same thing. The second one mutates x, and the first one creates a new list and assigns it to x. To see the difference, try setting y = x before adding anything to x and trying each one, and look at the difference the two make to y.

The answer offered by @Daniel Kamil Kozar is the correct answer - gettimeofday actually should not be used to measure the elapsed time. Use clock_gettime(CLOCK_MONOTONIC) instead.

Man Pages say - The time returned by gettimeofday() is affected by discontinuous jumps in the system time (e.g., if the system administrator manually changes the system time). If you need a monotonically increasing clock, see clock_gettime(2).

The Opengroup says - Applications should use the clock_gettime() function instead of the obsolescent gettimeofday() function.

Everyone seems to love gettimeofday until they run into a case where it does not work or is not there (VxWorks) ... clock_gettime is fantastically awesome and portable.

If you use IntelliJ IDEA you can browse all maven goals/tasks (including plugins) in Maven Projects tab:

if not exist "%USERPROFILE%\.qgis-custom\" (
    mkdir "%USERPROFILE%\.qgis-custom" 2>nul
    if not errorlevel 1 (
        xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
    )
)

You have it almost done. The logic is correct, just some little changes.

This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).

If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.

If everyting is ok, files are copied.

All paths are quoted to avoid problems with spaces.

It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files

mkdir "%USERPROFILE%\.qgis-custom" 2>nul 
if not errorlevel 1 (
    xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)

In both code samples, files are not copied if the folder is not being created during the script execution.

EDITED - As dbenham comments, the same code can be written as a single line

md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e

The code after the && will only be executed if the previous command does not set errorlevel. If mkdir fails, xcopy is not executed.

I would use the scheduler (control panel) rather than a cmd line or other application.

If you are using Grade, it is possible to apply the 'application' plugin rather than the 'java' plugin. This allows specifying the main class as below without using any Spring Boot Gradle plugin tasks.

plugins {
  id 'org.springframework.boot' version '2.3.3.RELEASE'
  id 'io.spring.dependency-management' version '1.0.10.RELEASE'
  id 'application'
}
application {
  mainClassName = 'com.example.ExampleApplication'
}

As a nice benefit, one is able to run the application using gradle run with the classpath automatically configured by Gradle. The plugin also packages the application as a TAR and/or ZIP including operating system specific start scripts.

I use this

<staticContent>
<clientCache cacheControlCustom="public" cacheControlMode="UseMaxAge" cacheControlMaxAge="500.00:00:00" />
</staticContent>

to cache static content for 500 days with public cache-control header.

If you have Div as follows in one Iframe

 <iframe id="ifrmReportViewer" name="ifrmReportViewer" frameborder="0" width="980"

     <div id="EndLetterSequenceNoToShow" runat="server"> 11441551 </div> Or

     <form id="form1" runat="server">        
       <div style="clear: both; width: 998px; margin: 0 auto;" id="divInnerForm">          

            Some Text

        </div>
     </form>
 </iframe>

Then you can find the text of those Div using the following code

var iContentBody = $("#ifrmReportViewer").contents().find("body");
var endLetterSequenceNo = iContentBody.find("#EndLetterSequenceNoToShow").text();

var divInnerFormText = iContentBody.find("#divInnerForm").text();

I hope this will help someone.

I don't know that much JQuery but I've heard it allows to fire native events with this syntax.

$(document).ready(function(){

    $('#countrylist').change(function(e){
       // Your event handler
    });

    // And now fire change event when the DOM is ready
    $('#countrylist').trigger('change');
});

You must declare the change event handler before calling trigger() or change() otherwise it won't be fired. Thanks for the mention @LenielMacaferi.

What worked for me was to set the Personal Access Token from github in a file .nextrc

ARG GITHUB_READ_TOKEN
RUN echo -e "machine github.com\n  login $GITHUB_READ_TOKEN" > ~/.netrc 
RUN npm install --only=production --force \
  && npm cache clean --force
RUN rm ~/.netrc

in package.json

"my-lib": "github:username/repo",

Since "$(this).parent().index();" and "$(this).parent('table').index();" don't work for me, I use this code instead:

$('td').click(function(){
   var row_index = $(this).closest("tr").index();
   var col_index = $(this).index();
});

In Core 2.2 Razor pages this syntax works:

    <button type="submit" name="Submit">Save</button>
    <button type="submit" name="Cancel">Cancel</button>
public async Task<IActionResult> OnPostAsync()
{
    if (!ModelState.IsValid)
        return Page();
    var sub = Request.Form["Submit"];
    var can = Request.Form["Cancel"];
    if (sub.Count > 0)
       {

If you have control over the structure of the list, the most pythonic thing to do would probably be to change it from:

l=[1,2,3,4]

to:

l=[(1,2),(3,4)]

Then, your loop would be:

for i,j in l:
    print i, j

Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.

if(isset($_POST["newsletter"]) && $_POST["newsletter"] == "newsletter"){
    //checked
}

The second parameter of findBy is for ORDER.

$ens = $em->getRepository('AcmeBinBundle:Marks')
          ->findBy(
             array('type'=> 'C12'), 
             array('id' => 'ASC')
           );

for python3.5+

from pathlib import Path

def get_size(path):
    return sum(p.stat().st_size for p in Path(path).rglob('*'))

If you have saved the excel file in the same folder as your python program (relative paths) then you just need to mention sheet number along with file name.

Example:

 data = pd.read_excel("wt_vs_ht.xlsx", "Sheet2")
 print(data)
 x = data.Height
 y = data.Weight
 plt.plot(x,y,'x')
 plt.show()

It seems the mysql connectivity library is not included in the project. Solve the problem following one of the proposed solutions:

• MAVEN PROJECTS SOLUTION

Add the mysql-connector dependency to the pom.xml project file:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.39</version>
</dependency>

Here you are all the versions: https://mvnrepository.com/artifact/mysql/mysql-connector-java

• ALL PROJECTS SOLUTION

Add the jar library manually to the project.

Right Click the project -- > build path -- > configure build path

In Libraries Tab press Add External Jar and Select your jar.

You can find zip for mysql-connector here

• Explanation:

When building the project, java throws you an exception because a file (the com.mysql.jdbc.Driver class) from the mysql connectivity library is not found. The solution is adding the library to the project, and java will find the com.mysql.jdbc.Driver

I also have used the table approach. However, there is overhead. Why store a second list of pointers? A function in C without the () is a const pointer. So you can do:

struct state;
typedef void (*state_func_t)( struct state* );

typedef struct state
{
  state_func_t function;

  // other stateful data

} state_t;

void do_state_initial( state_t* );
void do_state_foo( state_t* );
void do_state_bar( state_t* );

void run_state( state_t* i ) {
    i->function(i);
};

int main( void ) {
    state_t state = { do_state_initial };

    while ( 1 ) {
        run_state( state );

        // do other program logic, run other state machines, etc
    }
}

Of course depending on your fear factor (i.e. safety vs speed) you may want to check for valid pointers. For state machines larger than three or so states, the approach above should be less instructions than an equivalent switch or table approach. You could even macro-ize as:

#define RUN_STATE(state_ptr_) ((state_ptr_)->function(state_ptr_))

Also, I feel from the OP's example, that there is a simplification that should be done when thinking about / designing a state machine. I don't thing the transitioning state should be used for logic. Each state function should be able to perform its given role without explicit knowledge of past state(s). Basically you design for how to transition from the state you are in to another state.

Finally, don't start the design of a state machine based on "functional" boundaries, use sub-functions for that. Instead divide the states based on when you will have to wait for something to happen before you can continue. This will help minimize the number of times you have to run the state machine before you get a result. This can be important when writing I/O functions, or interrupt handlers.

Also, a few pros and cons of the classic switch statement:

Pros:

• it is in the language, so it is documented and clear
• states are defined where they are called
• can execute multiple states in one function call
• code common to all states can be executed before and after the switch statement

Cons:

• can execute multiple states in one function call
• code common to all states can be executed before and after the switch statement
• switch implementation can be slow

Note the two attributes that are both pro and con. I think the switch allows the opportunity for too much sharing between states, and the interdependency between states can become unmanageable. However for a small number of states, it may be the most readable and maintainable.

Is that what you need?

I don't see how that format is necessarily easy to work with in SQL queries, though.

Seaborn takes care of a lot of the manual work and automatically plots a gradient at the side of the chart etc.

import numpy as np
import seaborn as sns
import matplotlib.pylab as plt

uniform_data = np.random.rand(10, 12)
ax = sns.heatmap(uniform_data, linewidth=0.5)
plt.show()

Or, you can even plot upper / lower left / right triangles of square matrices, for example a correlation matrix which is square and is symmetric, so plotting all values would be redundant anyway.

corr = np.corrcoef(np.random.randn(10, 200))
mask = np.zeros_like(corr)
mask[np.triu_indices_from(mask)] = True
with sns.axes_style("white"):
    ax = sns.heatmap(corr, mask=mask, vmax=.3, square=True,  cmap="YlGnBu")
    plt.show()

The best bet with these types of questions is to see exactly what python does. The dis module is incredibly informative:

>>> import dis
>>> dis.dis("val != None")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               3 (!=)
              6 RETURN_VALUE
>>> dis.dis("not (val is None)")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               9 (is not)
              6 RETURN_VALUE
>>> dis.dis("val is not None")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               9 (is not)
              6 RETURN_VALUE

Notice that the last two cases reduce to the same sequence of operations, Python reads not (val is None) and uses the is not operator. The first uses the != operator when comparing with None.

As pointed out by other answers, using != when comparing with None is a bad idea.

Quick Answer

Use index_col=False instead of index_col=None when you have delimiters at the end of each line to turn off index column inference and discard the last column.

More Detail

After looking at the data, there is a comma at the end of each line. And this quote (the documentation has been edited since the time this post was created):

index_col: column number, column name, or list of column numbers/names, to use as the index (row labels) of the resulting DataFrame. By default, it will number the rows without using any column, unless there is one more data column than there are headers, in which case the first column is taken as the index.

from the documentation shows that pandas believes you have n headers and n+1 data columns and is treating the first column as the index.

EDIT 10/20/2014 - More information

I found another valuable entry that is specifically about trailing limiters and how to simply ignore them:

If a file has one more column of data than the number of column names, the first column will be used as the DataFrame’s row names: ...

Ordinarily, you can achieve this behavior using the index_col option.

There are some exception cases when a file has been prepared with delimiters at the end of each data line, confusing the parser. To explicitly disable the index column inference and discard the last column, pass index_col=False: ...

The only way you should be getting values "out of" an Observable/Subject is with subscribe!

If you're using getValue() you're doing something imperative in declarative paradigm. It's there as an escape hatch, but 99.9% of the time you should NOT use getValue(). There are a few interesting things that getValue() will do: It will throw an error if the subject has been unsubscribed, it will prevent you from getting a value if the subject is dead because it's errored, etc. But, again, it's there as an escape hatch for rare circumstances.

There are several ways of getting the latest value from a Subject or Observable in a "Rx-y" way:

1. Using BehaviorSubject: But actually subscribing to it. When you first subscribe to BehaviorSubject it will synchronously send the previous value it received or was initialized with.
2. Using a ReplaySubject(N): This will cache N values and replay them to new subscribers.
3. A.withLatestFrom(B): Use this operator to get the most recent value from observable B when observable A emits. Will give you both values in an array [a, b].
4. A.combineLatest(B): Use this operator to get the most recent values from A and B every time either A or B emits. Will give you both values in an array.
5. shareReplay(): Makes an Observable multicast through a ReplaySubject, but allows you to retry the observable on error. (Basically it gives you that promise-y caching behavior).
6. publishReplay(), publishBehavior(initialValue), multicast(subject: BehaviorSubject | ReplaySubject), etc: Other operators that leverage BehaviorSubject and ReplaySubject. Different flavors of the same thing, they basically multicast the source observable by funneling all notifications through a subject. You need to call connect() to subscribe to the source with the subject.

Solomon's answer about bootstrap inspired me to add the CSS the bootstrap solution uses, which works really well for me.

Although as other answers here have said you can change the "Output type" to "Windows Application", please be aware that this will mean that you cannot use Console.In as it will become a NullStreamReader.

Console.Out and Console.Error seem to still work fine however.

This could help you at some point.

a <- c(45,50,10,96)
a[order(a)]

What you get is

[1] 10 45 50 96

The code I wrote indicates you want "a" as a whole subset of "a" and you want it ordered from the lowest to highest value.

Have a look at Collections.sort() and the Comparator interface.

String comparison can be done with object1.getName().compareTo(object2.getName()) or object2.getName().compareTo(object1.getName()) (depending on the sort direction you desire).

If you want the sort to be case agnostic, do object1.getName().toUpperCase().compareTo(object2.getName().toUpperCase()).

static methods can be synchronized. But you have one lock per class. when the java class is loaded coresponding java.lang.class class object is there. That object's lock is needed for.static synchronized methods. So when you have a static field which should be restricted to be accessed by multiple threads at once you can set those fields private and create public static synchronized setters or getters to access those fields.

A basic and very simple way of doing this without any code required would be to just provide an empty alt statement. The browser will then return the image as blank. It would look just like if the image isn't there.

Example:

<img class="img_gal" alt="" src="awesome.jpg">

Try it out to see! ;)

Don't detect mobile devices, go for stationary ones instead.

Nowadays (2016) there is a way to detect dots per inch/cm/px that seems to work in most modern browsers (see http://caniuse.com/#feat=css-media-resolution). I needed a method to distinguish between a relatively small screen, orientation didn't matter, and a stationary computer monitor.

Because many mobile browsers don't support this, one can write the general css code for all cases and use this exception for large screens:

@media (max-resolution: 1dppx) {
    /* ... */
}

Both Windows XP and 7 have the default setting of 1 dot per pixel (or 96dpi). I don't know about other operating systems, but this works really well for my needs.

Edit: dppx doesn't seem to work in Internet Explorer.. use (96)dpi instead.

I believe Node.js is best suited for real-time applications: online games, collaboration tools, chat rooms, or anything where what one user (or robot? or sensor?) does with the application needs to be seen by other users immediately, without a page refresh.

I should also mention that Socket.IO in combination with Node.js will reduce your real-time latency even further than what is possible with long polling. Socket.IO will fall back to long polling as a worst case scenario, and instead use web sockets or even Flash if they are available.

But I should also mention that just about any situation where the code might block due to threads can be better addressed with Node.js. Or any situation where you need the application to be event-driven.

Also, Ryan Dahl said in a talk that I once attended that the Node.js benchmarks closely rival Nginx for regular old HTTP requests. So if we build with Node.js, we can serve our normal resources quite effectively, and when we need the event-driven stuff, it's ready to handle it.

Plus it's all JavaScript all the time. Lingua Franca on the whole stack.

Important to note it's \n (backslash) rather than /n.

Adding a step-by-step guide to @Codeply-er's answer above for SASS/SCSS newbies like me.

1. Save btnCustom.scss.

/* import the necessary Bootstrap files */
@import 'bootstrap';

/* Define color */
$mynewcolor:#77cccc;

.btn-custom {
    @include button-variant($mynewcolor, darken($mynewcolor, 7.5%), darken($mynewcolor, 10%), lighten($mynewcolor,5%), lighten($mynewcolor, 10%), darken($mynewcolor,30%));
}

.btn-outline-custom {
    @include button-outline-variant($mynewcolor, #222222, lighten($mynewcolor,5%), $mynewcolor);
}

2. Download a SASS compiler such as Koala so that SCSS file above can be compiled to CSS.
3. Clone the Bootstrap github repo because the compiler needs the button-variant mixins somewhere.
4. Explicitly import bootstrap functions by creating a _bootstrap.scss file as below. This will allow the compiler to access the Bootstrap functions and variables.

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/mixins";
@import "bootstrap/scss/root";
@import "bootstrap/scss/reboot";
@import "bootstrap/scss/type";
@import "bootstrap/scss/images";
@import "bootstrap/scss/grid";
@import "bootstrap/scss/tables";
@import "bootstrap/scss/forms";
@import "bootstrap/scss/buttons";
@import "bootstrap/scss/utilities";

5. Compile btnCustom.scss with the previously downloaded compiler to css.

On windows and Netbeans you can set the relative path as:

    new FileReader("src\\PACKAGE_NAME\\FILENAME");

On Linux and Netbeans you can set the relative path as:

    new FileReader("src/PACKAGE_NAME/FILENAME");

If you have your code inside Source Packages I do not know if it is the same for eclipse or other IDE

Like @gotgenes pointed out with Jenkins Version. 2.74, the below works, not sure since when, maybe if some one can edit and add the version above

cleanWs()

With, Jenkins Version 2.16 and the Workspace Cleanup Plugin, that I have, I use

step([$class: 'WsCleanup'])

to delete the workspace.

Then selecting "step: General Build Step" from Sample step and then selecting "Delete workspace when build is done" from Build step

var query = source.GroupBy(x => new { x.Column1, x.Column2 });

Addition to the above answer by @djechlin

d = '1394104654000';
new Date(parseInt(d));

converts EPOCH time to human readable date. Just don't forget that type of EPOCH time must be an Integer.

After hours of searching and looking for answer, finally I made it!!!!! Code is below :))))

HTML:

<form id="fileinfo" enctype="multipart/form-data" method="post" name="fileinfo">
    <label>File to stash:</label>
    <input type="file" name="file" required />
</form>
<input type="button" value="Stash the file!"></input>
<div id="output"></div>

jQuery:

$(function(){
    $('#uploadBTN').on('click', function(){ 
        var fd = new FormData($("#fileinfo"));
        //fd.append("CustomField", "This is some extra data");
        $.ajax({
            url: 'upload.php',  
            type: 'POST',
            data: fd,
            success:function(data){
                $('#output').html(data);
            },
            cache: false,
            contentType: false,
            processData: false
        });
    });
});

In the upload.php file you can access the data passed with $_FILES['file'].

Thanks everyone for trying to help:)

I took the answer from here (with some changes) MDN

You want \s

Matches a single white space character, including space, tab, form feed, line feed.

Equivalent to

[ \f\n\r\t\v\u00a0\u1680\u2000-\u200a\u2028\u2029\u202f\u205f\u3000\ufeff]

in Firefox and [ \f\n\r\t\v] in IE.

str = str.replace(/\s/g, "X");

Yes, you can split a string out onto multiple lines without introducing newlines into the actual string, but it aint pretty:

string s = $@"This string{
string.Empty} contains no newlines{
string.Empty} even though it is spread onto{
string.Empty} multiple lines.";

The trick is to introduce code that evaluates to empty, and that code may contain newlines without affecting the output. I adapted this approach from this answer to a similar question.

There is apparently some confusion as to what the question is, but there are two hints that what we want here is a string literal not containing any newline characters, whose definition spans multiple lines. (in the comments he says so, and "here's what I have" shows code that does not create a string with newlines in it)

This unit test shows the intent:

    [TestMethod]
    public void StringLiteralDoesNotContainSpaces()
    {
        string query = "hi"
                     + "there";
        Assert.AreEqual("hithere", query);
    }

Change the above definition of query so that it is one string literal, instead of the concatenation of two string literals which may or may not be optimized into one by the compiler.

The C++ approach would be to end each line with a backslash, causing the newline character to be escaped and not appear in the output. Unfortunately, there is still then the issue that each line after the first must be left aligned in order to not add additional whitespace to the result.

There is only one option that does not rely on compiler optimizations that might not happen, which is to put your definition on one line. If you want to rely on compiler optimizations, the + you already have is great; you don't have to left-align the string, you don't get newlines in the result, and it's just one operation, no function calls, to expect optimization on.

We're planning to use FitNesse, with the RestFixture. We haven't started writing our tests yet, our newest tester got things up and running last week, however he has used FitNesse for this in his last company, so we know it's a reasonable setup for what we want to do.

More info available here: http://smartrics.blogspot.com/2008/08/get-fitnesse-with-some-rest.html

All that the test attribute looks for to determine if something is true is the string "true" (case in-sensitive). For example, the following code will print "Hello world!"

<c:if test="true">Hello world!</c:if>

The code within the <%= %> returns a boolean, so it will either print the string "true" or "false", which is exactly what the <c:if> tag looks for.

You need to write it this way

<div 
    className="player"
    style={{ position: "absolute" }}
    onKeyDown={this.onKeyPressed}
    tabIndex="0"
  >

If onKeyPressed is not bound to this, then try to rewrite it using arrow function or bind it in the component constructor.

btw @aar doesn't have transitive dependency. you need a parameter to turn it on: Transitive dependencies not resolved for aar library using gradle

Try instead of db.parse(xml):

Document doc = db.parse(new InputSource(new StringReader(**xml**)));

Like Vatine wrote: Since go lacks generics it would have to be part of the language and not the standard library. For that you would then have to pollute the language with keywords set, union, intersection, difference, subset...

The other reason is, that it's not clear at all what the "right" implementation of a set is:

1. There is a functional approach:

   func IsInEvenNumbers(n int) bool {
       if n % 2 == 0 {
           return true
       }
      return false
   }
   

This is a set of all even ints. It has a very efficient lookup and union, intersect, difference and subset can easily be done by functional composition.

2. Or you do a has-like approach like Dali showed.

A map does not have that problem, since you store something associated with the value.

As Darin says, you can read from the input stream - but I'd avoid relying on all the data being available in a single go. If you're using .NET 4 this is simple:

MemoryStream target = new MemoryStream();
model.File.InputStream.CopyTo(target);
byte[] data = target.ToArray();

It's easy enough to write the equivalent of CopyTo in .NET 3.5 if you want. The important part is that you read from HttpPostedFileBase.InputStream.

For efficient purposes you could check whether the stream returned is already a MemoryStream:

byte[] data;
using (Stream inputStream = model.File.InputStream)
{
    MemoryStream memoryStream = inputStream as MemoryStream;
    if (memoryStream == null)
    {
        memoryStream = new MemoryStream();
        inputStream.CopyTo(memoryStream);
    }
    data = memoryStream.ToArray();
}

I also faced it and encorrected it like below successfully.

You may need to upgrade your gradle version.

You can use the SO_RCVTIMEO and SO_SNDTIMEO socket options to set timeouts for any socket operations, like so:

    struct timeval timeout;      
    timeout.tv_sec = 10;
    timeout.tv_usec = 0;

    if (setsockopt (sockfd, SOL_SOCKET, SO_RCVTIMEO, (char *)&timeout,
                sizeof(timeout)) < 0)
        error("setsockopt failed\n");

    if (setsockopt (sockfd, SOL_SOCKET, SO_SNDTIMEO, (char *)&timeout,
                sizeof(timeout)) < 0)
        error("setsockopt failed\n");

Edit: from the setsockopt man page:

SO_SNDTIMEO is an option to set a timeout value for output operations. It accepts a struct timeval parameter with the number of seconds and microseconds used to limit waits for output operations to complete. If a send operation has blocked for this much time, it returns with a partial count or with the error EWOULDBLOCK if no data were sent. In the current implementation, this timer is restarted each time additional data are delivered to the protocol, implying that the limit applies to output portions ranging in size from the low-water mark to the high-water mark for output.

SO_RCVTIMEO is an option to set a timeout value for input operations. It accepts a struct timeval parameter with the number of seconds and microseconds used to limit waits for input operations to complete. In the current implementation, this timer is restarted each time additional data are received by the protocol, and thus the limit is in effect an inactivity timer. If a receive operation has been blocked for this much time without receiving additional data, it returns with a short count or with the error EWOULDBLOCK if no data were received. The struct timeval parameter must represent a positive time interval; otherwise, setsockopt() returns with the error EDOM.

I use this technique for pagination. I do not fetch all the rows. For example, if my page needs to display the top 100 rows I fetch only the 100 with where clause. The output of the SQL should have a unique key.

The table has the following:

ID, KeyId, Rank

The same rank will be assigned for more than one KeyId.

SQL is select top 2 * from Table1 where Rank >= @Rank and ID > @Id

For the first time I pass 0 for both. The second time pass 1 & 14. 3rd time pass 2 and 6....

The value of the 10th record Rank & Id is passed to the next

11  21  1
14  22  1
7   11  1
6   19  2
12  31  2
13  18  2

This will have the least stress on the system

function removeParam(parameter)
{
  var url=document.location.href;
  var urlparts= url.split('?');

 if (urlparts.length>=2)
 {
  var urlBase=urlparts.shift(); 
  var queryString=urlparts.join("?"); 

  var prefix = encodeURIComponent(parameter)+'=';
  var pars = queryString.split(/[&;]/g);
  for (var i= pars.length; i-->0;)               
      if (pars[i].lastIndexOf(prefix, 0)!==-1)   
          pars.splice(i, 1);
  url = urlBase+'?'+pars.join('&');
  window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .

}
return url;
}

This will resolve your problem

In some languages this can be solved with tail call optimization, where the recursion call is transformed under the hood into a loop so no maximum stack size reached error exists.

But in javascript the current engines don't support this, it's foreseen for new version of the language Ecmascript 6.

Node.js has some flags to enable ES6 features but tail call is not yet available.

So you can refactor your code to implement a technique called trampolining, or refactor in order to transform recursion into a loop.

Board.setPreferredSize(new Dimension(x, y));

Checksum all files, including both content and their filenames

grep -ar -e . /your/dir | md5sum | cut -c-32

Same as above, but only including *.py files

grep -ar -e . --include="*.py" /your/dir | md5sum | cut -c-32

You can also follow symlinks if you want

grep -aR -e . /your/dir | md5sum | cut -c-32

Other options you could consider using with grep

-s, --no-messages         suppress error messages
-D, --devices=ACTION      how to handle devices, FIFOs and sockets;
-Z, --null                print 0 byte after FILE name
-U, --binary              do not strip CR characters at EOL (MSDOS/Windows)

The Gradle answer is to add a jar/manifest/attributes setting like this:

apply plugin: 'java'

jar {
    manifest {
        attributes 'Main-Class': 'com.package.app.Class'
    }
}

I do it like this:

func checkMaxLength(textField: UITextField!, maxLength: Int) {
    if (countElements(textField.text!) > maxLength) {
        textField.deleteBackward()
    }
}

The code works for me. But I work with storyboard. In Storyboard I add an action for the text field in the view controller on editing changed.

To terminate a process you know the name of, try:

taskkill /IM notepad.exe

This will ask it to close, but it may refuse, offer to "save changes", etc. If you want to forcibly kill it, try:

taskkill /F /IM notepad.exe

I know this post is a couple years old, but I keep running into this and I'm not happy with the service locator pattern.

Also, I know the OP is looking for an implementation which allows you to choose a concrete implementation based on a string. I also realize that the OP is specifically asking for an implementation of an identical interface. The solution I'm about to describe relies on adding a generic type parameter to your interface. The problem is that you don't have any real use for the type parameter other than service collection binding. I'll try to describe a situation which might require something like this.

Imagine configuration for such a scenario in appsettings.json which might look something like this (this is just for demonstration, your configuration can come from wherever you want as long as you have the correction configuration provider):

{
  "sqlDataSource": {
    "connectionString": "Data Source=localhost; Initial catalog=Foo; Connection Timeout=5; Encrypt=True;",
    "username": "foo",
    "password": "this normally comes from a secure source, but putting here for demonstration purposes"
  },
  "mongoDataSource": {
    "hostName": "uw1-mngo01-cl08.company.net",
    "port": 27026,
    "collection": "foo"
  }
}

You really need a type that represents each of your configuration options:

public class SqlDataSource
{
  public string ConnectionString { get;set; }
  public string Username { get;set; }
  public string Password { get;set; }
}

public class MongoDataSource
{
  public string HostName { get;set; }
  public string Port { get;set; }
  public string Collection { get;set; }
}

Now, I know that it might seem a little contrived to have two implementations of the same interface, but it I've definitely seen it in more than one case. The ones I usually come across are:

1. When migrating from one data store to another, it's useful to be able to implement the same logical operations using the same interfaces so that you don't need to change the calling code. This also allows you to add configuration which swaps between different implementations at runtime (which can be useful for rollback).
2. When using the decorator pattern. The reason you might use that pattern is that you want to add functionality without changing the interface and fall back to the existing functionality in certain cases (I've used it when adding caching to repository classes because I want circuit breaker-like logic around connections to the cache that fall back to the base repository -- this gives me optimal behavior when the cache is available, but behavior that still functions when it's not).

Anyway, you can reference them by adding a type parameter to your service interface so that you can implement the different implementations:

public interface IService<T> {
  void DoServiceOperation();
}

public class MongoService : IService<MongoDataSource> {
  private readonly MongoDataSource _options;

  public FooService(IOptionsMonitor<MongoDataSource> serviceOptions){
    _options = serviceOptions.CurrentValue
  }

  void DoServiceOperation(){
    //do something with your mongo data source options (connect to database)
    throw new NotImplementedException();
  }
}

public class SqlService : IService<SqlDataSource> {
  private readonly SqlDataSource_options;

  public SqlService (IOptionsMonitor<SqlDataSource> serviceOptions){
    _options = serviceOptions.CurrentValue
  }

  void DoServiceOperation(){
    //do something with your sql data source options (connect to database)
    throw new NotImplementedException();
  }
}

In startup, you'd register these with the following code:

services.Configure<SqlDataSource>(configurationSection.GetSection("sqlDataSource"));
services.Configure<MongoDataSource>(configurationSection.GetSection("mongoDataSource"));

services.AddTransient<IService<SqlDataSource>, SqlService>();
services.AddTransient<IService<MongoDataSource>, MongoService>();

Finally in the class which relies on the Service with a different connection, you just take a dependency on the service you need and the DI framework will take care of the rest:

[Route("api/v1)]
[ApiController]
public class ControllerWhichNeedsMongoService {  
  private readonly IService<MongoDataSource> _mongoService;
  private readonly IService<SqlDataSource> _sqlService ;

  public class ControllerWhichNeedsMongoService(
    IService<MongoDataSource> mongoService, 
    IService<SqlDataSource> sqlService
  )
  {
    _mongoService = mongoService;
    _sqlService = sqlService;
  }

  [HttpGet]

These implementations can even take a dependency on each other. The other big benefit is that you get compile-time binding so any refactoring tools will work correctly.

Hope this helps someone in the future.

Nothing work for me but when i set tint color it works on Shape Drawable

 Drawable background = imageView.getBackground();
 background.setTint(getRandomColor())

require android 5.0 API 21

I also faced this problem and fixed it by removing version part from the XSD name.

http://www.springframework.org/schema/beans/spring-beans-4.2.xsd to http://www.springframework.org/schema/beans/spring-beans.xsd

Versions less XSD's are mapped to the current version of the framework used in the application.

On Excel for Mac 2011, the newline had to be a \r instead of an \n

So

"\"first line\rsecond line\""

would show up as a cell with 2 lines

You can also remove the line

  require: 'ngModel',

if you don't need ngModel in this directive. Removing ngModel will allow you to make a directive without thatngModel error.

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}

Using KeyGenerator would be the preferred method. As Duncan indicated, I would certainly give the key size during initialization. KeyFactory is a method that should be used for pre-existing keys.

OK, so lets get to the nitty-gritty of this. In principle AES keys can have any value. There are no "weak keys" as in (3)DES. Nor are there any bits that have a specific meaning as in (3)DES parity bits. So generating a key can be as simple as generating a byte array with random values, and creating a SecretKeySpec around it.

But there are still advantages to the method you are using: the KeyGenerator is specifically created to generate keys. This means that the code may be optimized for this generation. This could have efficiency and security benefits. It might be programmed to avoid a timing side channel attacks that would expose the key, for instance. Note that it may already be a good idea to clear any byte[] that hold key information as they may be leaked into a swap file (this may be the case anyway though).

Furthermore, as said, not all algorithms are using fully random keys. So using KeyGenerator would make it easier to switch to other algorithms. More modern ciphers will only accept fully random keys though; this is seen as a major benefit over e.g. DES.

Finally, and in my case the most important reason, it that the KeyGenerator method is the only valid way of handling AES keys within a secure token (smart card, TPM, USB token or HSM). If you create the byte[] with the SecretKeySpec then the key must come from memory. That means that the key may be put in the secure token, but that the key is exposed in memory regardless. Normally, secure tokens only work with keys that are either generated in the secure token or are injected by e.g. a smart card or a key ceremony. A KeyGenerator can be supplied with a provider so that the key is directly generated within the secure token.

As indicated in Duncan's answer: always specify the key size (and any other parameters) explicitly. Do not rely on provider defaults as this will make it unclear what your application is doing, and each provider may have its own defaults.

Please see https://angular.io/guide/pipes#appendix-no-filterpipe-or-orderbypipe for the full discussion. This quote is most relevant. Basically, for large scale apps that should be minified aggressively the filtering and sorting logic should move to the component itself.

"Some of us may not care to minify this aggressively. That's our choice. But the Angular product should not prevent someone else from minifying aggressively. Therefore, the Angular team decided that everything shipped in Angular will minify safely.

The Angular team and many experienced Angular developers strongly recommend that you move filtering and sorting logic into the component itself. The component can expose a filteredHeroes or sortedHeroes property and take control over when and how often to execute the supporting logic. Any capabilities that you would have put in a pipe and shared across the app can be written in a filtering/sorting service and injected into the component."

In Swift 3.0+, UIBarButtonItem programmatically set up as follows:

   override func viewDidLoad() {
        super.viewDidLoad()
        let testUIBarButtonItem = UIBarButtonItem(image: UIImage(named: "test.png"), style: .plain, target: self, action: #selector(self.clickButton))
        self.navigationItem.rightBarButtonItem  = testUIBarButtonItem
    }

   @objc func clickButton(){
            print("button click")
     }

Another kludge, ugh, but it's easy and works for me in VS 2013. Click on the project. In the properties panel should be an entry named Project File with a value

(your project name).vbproj

Change the project name - such as adding an -01 to the end. The original .zip file that was locked is still there, but no longer referenced ... so your work can continue. Next time the computer is rebooted, that lock disappears and you can delete the errant file.

You can, using CSS variables (more precisely called CSS custom properties).

• Set your variable in your style attribute:
  style="--my-color-var: orange;"
• Use the variable in your stylesheet:
  background-color: var(--my-color-var);

Browser compatibility

Minimal example:

div {
  width: 100px;
  height: 100px;
  position: relative;
  border: 1px solid black;
}

div:after {
  background-color: var(--my-color-var);
  content: '';
  position: absolute;
  top: 0;
  bottom: 0;
  right: 0;
  left: 0;
}

<div style="--my-color-var: orange;"></div>

Your example:

.bubble {
  position: relative;
  width: 30px;
  height: 15px;
  padding: 0;
  background: #FFF;
  border: 1px solid #000;
  border-radius: 5px;
  text-align: center;
  background-color: var(--bubble-color);
}

.bubble:after {
  content: "";
  position: absolute;
  top: 4px;
  left: -4px;
  border-style: solid;
  border-width: 3px 4px 3px 0;
  border-color: transparent var(--bubble-color);
   display: block;
  width: 0;
  z-index: 1;
  
}

.bubble:before {
  content: "";
  position: absolute;
  top: 4px;
  left: -5px;
  border-style: solid;
  border-width: 3px 4px 3px 0;
  border-color: transparent #000;
  display: block;
  width: 0;
  z-index: 0;
}

<div class='bubble' style="--bubble-color: rgb(100,255,255);"> 100 </div>

This will show image of base 64 data:

<style>
.logo {
      width: 290px;
      height: 63px;
      background: url(data:image/png;base64,copy-paste-base64-data-here) no-repeat;
}
</style>

<div class="logo"></div>

Below command will work in command prompt:

copy c:\folder\file.ext \\dest-machine\destfolder /Z /Y

To Copy all files:

copy c:\folder\*.* \\dest-machine\destfolder /Z /Y

As an addition to @ANisus' answer...

below is some information from the "Go in action" book, which I think is worth mentioning:

Difference between nil & empty slices

If we think of a slice like this:

[pointer] [length] [capacity]

then:

nil slice:   [nil][0][0]
empty slice: [addr][0][0] // points to an address

nil slice

They’re useful when you want to represent a slice that doesn’t exist, such as when an exception occurs in a function that returns a slice.

// Create a nil slice of integers.
var slice []int

empty slice

Empty slices are useful when you want to represent an empty collection, such as when a database query returns zero results.

// Use make to create an empty slice of integers.
slice := make([]int, 0)

// Use a slice literal to create an empty slice of integers.
slice := []int{}

Regardless of whether you’re using a nil slice or an empty slice, the built-in functions append, len, and cap work the same.

Go playground example:

package main

import (
    "fmt"
)

func main() {

    var nil_slice []int
    var empty_slice = []int{}

    fmt.Println(nil_slice == nil, len(nil_slice), cap(nil_slice))
    fmt.Println(empty_slice == nil, len(empty_slice), cap(empty_slice))

}

prints:

true 0 0
false 0 0

The problem is that Properties implements Map<Object, Object>, whereas the HashMap constructor expects a Map<? extends String, ? extends String>.

This answer explains this (quite counter-intuitive) decision. In short: before Java 5, Properties implemented Map (as there were no generics back then). This meant that you could put any Object in a Properties object. This is still in the documenation:

Because Properties inherits from Hashtable, the put and putAll methods can be applied to a Properties object. Their use is strongly discouraged as they allow the caller to insert entries whose keys or values are not Strings. The setProperty method should be used instead.

To maintain compatibility with this, the designers had no other choice but to make it inherit Map<Object, Object> in Java 5. It's an unfortunate result of the strive for full backwards compatibility which makes new code unnecessarily convoluted.

If you only ever use string properties in your Properties object, you should be able to get away with an unchecked cast in your constructor:

Map<String, String> map = new HashMap<String, String>( (Map<String, String>) properties);

or without any copies:

Map<String, String> map = (Map<String, String>) properties;

I have found this useful more than once when the DataGrid is bound to a table.

        DataTable dt = (DataTable)dgvData.DataSource;
        DataRow row = dt.NewRow();
        foreach (var something in something)
        {
           row["ColumnName"] = something ;               
        }
        dt.Rows.Add(row);
        dgvData.DataSource = dt;

Add one more slash after file:// in the value of xsi:schemaLocation. (You have two; you need three. Think protocol://host/path where protocol is 'file' and host is empty here, yielding three slashes in a row.) You can also eliminate the double slashes along the path. I believe that the double slashes help with file systems that allow spaces in file and directory names, but you wisely avoided that complication in your path naming.

xsi:schemaLocation="http://www.w3schools.com file:///C:/environment/workspace/maven-ws/ProjextXmlSchema/email.xsd"

Still not working? I suggest that you carefully copy the full file specification for the XSD into the address bar of Chrome or Firefox:

file:///C:/environment/workspace/maven-ws/ProjextXmlSchema/email.xsd

If the XSD does not display in the browser, delete all but the last component of the path (email.xsd) and see if you can't display the parent directory. Continue in this manner, walking up the directory structure until you discover where the path diverges from the reality of your local filesystem.

If the XSD does displayed in the browser, state what XML processor you're using, and be prepared to hear that it's broken or that you must work around some limitation. I can tell you that the above fix will work with my Xerces-J-based validator.

if any interested I've made a typescript version:

interface IResizeImageOptions {
  maxSize: number;
  file: File;
}
const resizeImage = (settings: IResizeImageOptions) => {
  const file = settings.file;
  const maxSize = settings.maxSize;
  const reader = new FileReader();
  const image = new Image();
  const canvas = document.createElement('canvas');
  const dataURItoBlob = (dataURI: string) => {
    const bytes = dataURI.split(',')[0].indexOf('base64') >= 0 ?
        atob(dataURI.split(',')[1]) :
        unescape(dataURI.split(',')[1]);
    const mime = dataURI.split(',')[0].split(':')[1].split(';')[0];
    const max = bytes.length;
    const ia = new Uint8Array(max);
    for (var i = 0; i < max; i++) ia[i] = bytes.charCodeAt(i);
    return new Blob([ia], {type:mime});
  };
  const resize = () => {
    let width = image.width;
    let height = image.height;

    if (width > height) {
        if (width > maxSize) {
            height *= maxSize / width;
            width = maxSize;
        }
    } else {
        if (height > maxSize) {
            width *= maxSize / height;
            height = maxSize;
        }
    }

    canvas.width = width;
    canvas.height = height;
    canvas.getContext('2d').drawImage(image, 0, 0, width, height);
    let dataUrl = canvas.toDataURL('image/jpeg');
    return dataURItoBlob(dataUrl);
  };

  return new Promise((ok, no) => {
      if (!file.type.match(/image.*/)) {
        no(new Error("Not an image"));
        return;
      }

      reader.onload = (readerEvent: any) => {
        image.onload = () => ok(resize());
        image.src = readerEvent.target.result;
      };
      reader.readAsDataURL(file);
  })    
};

and here's the javascript result:

var resizeImage = function (settings) {
    var file = settings.file;
    var maxSize = settings.maxSize;
    var reader = new FileReader();
    var image = new Image();
    var canvas = document.createElement('canvas');
    var dataURItoBlob = function (dataURI) {
        var bytes = dataURI.split(',')[0].indexOf('base64') >= 0 ?
            atob(dataURI.split(',')[1]) :
            unescape(dataURI.split(',')[1]);
        var mime = dataURI.split(',')[0].split(':')[1].split(';')[0];
        var max = bytes.length;
        var ia = new Uint8Array(max);
        for (var i = 0; i < max; i++)
            ia[i] = bytes.charCodeAt(i);
        return new Blob([ia], { type: mime });
    };
    var resize = function () {
        var width = image.width;
        var height = image.height;
        if (width > height) {
            if (width > maxSize) {
                height *= maxSize / width;
                width = maxSize;
            }
        } else {
            if (height > maxSize) {
                width *= maxSize / height;
                height = maxSize;
            }
        }
        canvas.width = width;
        canvas.height = height;
        canvas.getContext('2d').drawImage(image, 0, 0, width, height);
        var dataUrl = canvas.toDataURL('image/jpeg');
        return dataURItoBlob(dataUrl);
    };
    return new Promise(function (ok, no) {
        if (!file.type.match(/image.*/)) {
            no(new Error("Not an image"));
            return;
        }
        reader.onload = function (readerEvent) {
            image.onload = function () { return ok(resize()); };
            image.src = readerEvent.target.result;
        };
        reader.readAsDataURL(file);
    });
};

usage is like:

resizeImage({
    file: $image.files[0],
    maxSize: 500
}).then(function (resizedImage) {
    console.log("upload resized image")
}).catch(function (err) {
    console.error(err);
});

or (async/await):

const config = {
    file: $image.files[0],
    maxSize: 500
};
const resizedImage = await resizeImage(config)
console.log("upload resized image")

Here is the way I include lots of classes from several folders in PHP 5. This will only work if you have classes though.

/*Directories that contain classes*/
$classesDir = array (
    ROOT_DIR.'classes/',
    ROOT_DIR.'firephp/',
    ROOT_DIR.'includes/'
);
function __autoload($class_name) {
    global $classesDir;
    foreach ($classesDir as $directory) {
        if (file_exists($directory . $class_name . '.php')) {
            require_once ($directory . $class_name . '.php');
            return;
        }
    }
}

It works for me:

CREATE TABLE `users`(
    `user_id` INT(10) NOT NULL AUTO_INCREMENT,
    `username` VARCHAR(255) NOT NULL,
    `password` VARCHAR(255) NOT NULL,
    PRIMARY KEY (`user_id`)
) ENGINE = MyISAM;       

simple to fix you re is :

// example.d.ts
declare module 'foo';

if you want to declarate interface of object (Recommend for big project) you can use :

// example.d.ts
declare module 'foo'{
    // example
    export function getName(): string
}

How to use that? simple..

const x = require('foo') // or import x from 'foo'
x.getName() // intellisense can read this

The problem in my case was that I needed to add environment variables for http_proxy and https_proxy.

E.g.,

http_proxy=http://your_proxy:your_port
https_proxy=https://your_proxy:your_port

To set these environment variables in Windows, see the answers to this question.

Replace the contents of the first <directory> tag.

Remove:

<Directory /usr/share/phpMyAdmin/>
 <IfModule mod_authz_core.c>
  # Apache 2.4
  <RequireAny>
    Require ip 127.0.0.1
    Require ip ::1
  </RequireAny>
 </IfModule>
 <IfModule !mod_authz_core.c>
  # Apache 2.2
  Order Deny,Allow
  Deny from All
  Allow from 127.0.0.1
  Allow from ::1
 </IfModule>
</Directory>

And place this instead:

<Directory /usr/share/phpMyAdmin/>
 Order allow,deny
 Allow from all
</Directory>

Don't forget to restart Apache afterwards.

Use the stringInsert function rather than the putinplace function. I was using the later function to parse a mysql query. Although the output looked alright, the query resulted in a error which took me a while to track down. The following is my version of the stringInsert function requiring only one parameter.

function stringInsert($str,$insertstr,$pos)
{
    $str = substr($str, 0, $pos) . $insertstr . substr($str, $pos);
    return $str;
}  

Here's another view using collections.abc. This view may be useful the second time around or later.

From collections.abc we can see the following hierarchy:

builtins.object
    Iterable
        Iterator
            Generator

i.e. Generator is derived from Iterator is derived from Iterable is derived from the base object.

Hence,

• Every iterator is an iterable, but not every iterable is an iterator. For example, [1, 2, 3] and range(10) are iterables, but not iterators. x = iter([1, 2, 3]) is an iterator and an iterable.
• A similar relationship exists between Iterator and Generator.
• Calling iter() on an iterator or a generator returns itself. Thus, if it is an iterator, then iter(it) is it is True.
• Under the hood, a list comprehension like [2 * x for x in nums] or a for loop like for x in nums:, acts as though iter() is called on the iterable (nums) and then iterates over nums using that iterator. Hence, all of the following are functionally equivalent (with, say, nums=[1, 2, 3]):
  • for x in nums:
  • for x in iter(nums):
  • for x in iter(iter(nums)):
  • for x in iter(iter(iter(iter(iter(nums))))):

• What is the most typical/common way of doing this with an object C++ (that doesn't involve overloading the == operator)?
• Is this even the right approach? ie. should I not write functions that take an object as an argument, but rather, write member functions? (But even if so, please answer the original question.)

No, references cannot be null (unless Undefined Behavior has already happened, in which case all bets are already off). Whether you should write a method or non-method depends on other factors.

• Between a function that takes a reference to an object, or a function that takes a C-style pointer to an object, are there reasons to choose one over the other?

If you need to represent "no object", then pass a pointer to the function, and let that pointer be NULL:

int silly_sum(int const* pa=0, int const* pb=0, int const* pc=0) {
  /* Take up to three ints and return the sum of any supplied values.

  Pass null pointers for "not supplied".

  This is NOT an example of good code.
  */
  if (!pa && (pb || pc)) return silly_sum(pb, pc);
  if (!pb && pc) return silly_sum(pa, pc);
  if (pc) return silly_sum(pa, pb) + *pc;
  if (pa && pb) return *pa + *pb;
  if (pa) return *pa;
  if (pb) return *pb;
  return 0;
}

int main() {
  int a = 1, b = 2, c = 3;
  cout << silly_sum(&a, &b, &c) << '\n';
  cout << silly_sum(&a, &b) << '\n';
  cout << silly_sum(&a) << '\n';
  cout << silly_sum(0, &b, &c) << '\n';
  cout << silly_sum(&a, 0, &c) << '\n';
  cout << silly_sum(0, 0, &c) << '\n';
  return 0;
}

If "no object" never needs to be represented, then references work fine. In fact, operator overloads are much simpler because they take overloads.

You can use something like boost::optional.

QPushButton *button = new QPushButton;
button->setIcon(QIcon(":/icons/..."));
button->setIconSize(QSize(65, 65));

If you are using Sql Server 2005 you can use table valued functions. You can call these directly and pass paramters, whilst treating them as if they were tables.

For more info check out Table-Valued User-Defined Functions

You can use a simple regex like this:

public static string StripHTML(string input)
{
   return Regex.Replace(input, "<.*?>", String.Empty);
}

Be aware that this solution has its own flaw. See Remove HTML tags in String for more information (especially the comments of @mehaase)

Another solution would be to use the HTML Agility Pack.
You can find an example using the library here: HTML agility pack - removing unwanted tags without removing content?

I have tried this, and this is working for me:

var table = document.getElementById("myTable");
var row = table.insertRow(myTable.rows.length-2);
var cell1 = row.insertCell(0);

If you are using FormBuilder, see @dfsq's answer.

If you are not using FormBuilder, there are two ways to be notified of changes.

Method 1

As discussed in the comments on the question, use an event binding on each input element. Add to your template:

<input type="text" class="form-control" required [ngModel]="model.first_name"
         (ngModelChange)="doSomething($event)">

Then in your component:

doSomething(newValue) {
  model.first_name = newValue;
  console.log(newValue)
}

The Forms page has some additional information about ngModel that is relevant here:

The ngModelChange is not an <input> element event. It is actually an event property of the NgModel directive. When Angular sees a binding target in the form [(x)], it expects the x directive to have an x input property and an xChange output property.

The other oddity is the template expression, model.name = $event. We're used to seeing an $event object coming from a DOM event. The ngModelChange property doesn't produce a DOM event; it's an Angular EventEmitter property that returns the input box value when it fires..

We almost always prefer [(ngModel)]. We might split the binding if we had to do something special in the event handling such as debounce or throttle the key strokes.

In your case, I suppose you want to do something special.

Method 2

Define a local template variable and set it to ngForm.
Use ngControl on the input elements.
Get a reference to the form's NgForm directive using @ViewChild, then subscribe to the NgForm's ControlGroup for changes:

<form #myForm="ngForm" (ngSubmit)="onSubmit()">
  ....
  <input type="text" ngControl="firstName" class="form-control" 
   required [(ngModel)]="model.first_name">
  ...
  <input type="text" ngControl="lastName" class="form-control" 
   required [(ngModel)]="model.last_name">

class MyForm {
  @ViewChild('myForm') form;
  ...
  ngAfterViewInit() {
    console.log(this.form)
    this.form.control.valueChanges
      .subscribe(values => this.doSomething(values));
  }
  doSomething(values) {
    console.log(values);
  }
}

plunker

For more information on Method 2, see Savkin's video.

See also @Thierry's answer for more information on what you can do with the valueChanges observable (such as debouncing/waiting a bit before processing changes).

The resources used for initializing the project are preferably put in src/main/resources folder. To enable loading of these resources during the build, one can simply add entries in the pom.xml in maven project as a build resource

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering> 
        </resource>
    </resources>
</build> 

Other .properties files can also be kept in this folder used for initialization. Filtering is set true if you want to have some variables in the properties files of resources folder and populate them from the profile filters properties files, which are kept in src/main/filters which is set as profiles but it is a different use case altogether. For now, you can ignore them.

This is a great resource maven resource plugins, it's useful, just browse through other sections too.

also you can use this :

    if (! $('#leftmenu').children().length > 0 ) {
         // do something : e.x : remove a specific div
    }

I think it'll work for you !

The most similar C# Select analogue would be a map function. Just use:

var ids = selectedFruits.map(fruit => fruit.id);

to select all ids from selectedFruits array.

It doesn't require any external dependencies, just pure JavaScript. You can find map documentation here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

You must change the cmake C/CXX default FLAGS .

According to CMAKE_BUILD_TYPE={DEBUG/MINSIZEREL/RELWITHDEBINFO/RELEASE} put in the main CMakeLists.txt one of :

For C

set(CMAKE_C_FLAGS_DEBUG "put your flags")
set(CMAKE_C_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_C_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_C_FLAGS_RELEASE "put your flags")

For C++

set(CMAKE_CXX_FLAGS_DEBUG "put your flags")
set(CMAKE_CXX_FLAGS_MINSIZEREL "put your flags")
set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "put your flags")
set(CMAKE_CXX_FLAGS_RELEASE "put your flags")

This will override the values defined in CMakeCache.txt

Smart Code: I am using following code so that every thing remains clear and readable. out side body will close the dialog box.

$(document).ready(function () {
   $('body').on('click', '.ui-widget-overlay', closeDialogBox);
});

function closeDialogBox() {
    $('#dialog-message').dialog('close');
}

Maybe unrelated to the original reason in this question, but for those who would face same with gradle and local module dependency

dependencies {
    checkstyle project(":module")
}

this error could happen, if module doesn't contain group and version, so in the module/build.gradle just need to be specified

plugins {
    id 'java-library'
}

group = "com.example"
version = "master-SNAPSHOT"

Here's another way to set directories to 775 and files to 664.

find /opt/lampp/htdocs \
\( -type f -exec chmod ug+rw,o+r {} \; \) , \
\( -type d -exec chmod ug+rwxs,o+rx {} \; \)

It may look long, but it's pretty cool for three reasons:

1. Scans through the file system only once rather than twice.
2. Provides better control over how files are handled vs. how directories are handled. This is useful when working with special modes such as the sticky bit, which you probably want to apply to directories but not files.
3. Uses a technique straight out of the man pages (see below).

Note that I have not confirmed the performance difference (if any) between this solution and that of simply using two find commands (as in Peter Mortensen's solution). However, seeing a similar example in the manual is encouraging.

Example from man find page:

find / \
\( -perm -4000 -fprintf /root/suid.txt %#m %u %p\n \) , \
\( -size +100M -fprintf /root/big.txt %-10s %p\n \)

Traverse the filesystem just once, listing setuid files and direct-
tories into /root/suid.txt and large files into /root/big.txt.

Take away the spaces. So do:

matches <- unique(grep("A1|A9|A6", myfile$Letter, value=TRUE, fixed=TRUE))

other than using this.form.submit() you also submiting by id or name. example i have form like this : <form action="" name="PostName" id="IdName">

1. By Name : <select onchange="PostName.submit()">

2. By Id : <select onchange="IdName.submit()">

The proper syntax would be - ALTER TABLE Table_Name ADD UNIQUE (column_name)

Example

ALTER TABLE  0_value_addition_setup ADD UNIQUE (`value_code`)
