"tint uiimage grayscale" appears to be the appropriate Google-Fu for this one

straight away I get:

How would I tint an image programmatically on the iPhone?

Try autoplay="autoplay" instead of the "true" value. That's the documented way to enable autoplay. That sounds weirdly redundant, I know.

    private Paint green = new Paint();

    private int greenx , greeny;


 green.setColor(Color.GREEN);

        green.setAntiAlias(false);

        canvas.drawCircle(greenx,greeny,20,green);

In VirtualBox you should add custom resolution via the command:

VBoxManage setextradata "VM name" "CustomVideoMode1" "800x480x16"

instead of editing a .vbox file.

This solution works fine for me!

This will cause Lint to ignore the missing translation error for ALL strings in the file, yet other string resource files can be verified if needed.

Default escape character in Java is '\'.
However, Java properties file has format key=value, it should be considering everything after the first equal as value.

In C++ the stack memory is where local variables get stored/constructed. The stack is also used to hold parameters passed to functions.

The stack is very much like the std::stack class: you push parameters onto it and then call a function. The function then knows that the parameters it expects can be found on the end of the stack. Likewise, the function can push locals onto the stack and pop them off it before returning from the function. (caveat - compiler optimizations and calling conventions all mean things aren't this simple)

The stack is really best understood from a low level and I'd recommend Art of Assembly - Passing Parameters on the Stack. Rarely, if ever, would you consider any sort of manual stack manipulation from C++.

Generally speaking, the stack is preferred as it is usually in the CPU cache, so operations involving objects stored on it tend to be faster. However the stack is a limited resource, and shouldn't be used for anything large. Running out of stack memory is called a Stack buffer overflow. It's a serious thing to encounter, but you really shouldn't come across one unless you have a crazy recursive function or something similar.

Heap memory is much as rskar says. In general, C++ objects allocated with new, or blocks of memory allocated with the likes of malloc end up on the heap. Heap memory almost always must be manually freed, though you should really use a smart pointer class or similar to avoid needing to remember to do so. Running out of heap memory can (will?) result in a std::bad_alloc.

The SGI STL has an extension called select1st. Too bad it's not in standard STL!

In NodeJS, __filename.split(/\|//).pop() returns just the file name from the absolute file path on any OS platform. Why need to care about remembering/importing an API while this regex approach also letting us recollect our regex skills.

For sake of simplicity, maybe you should consider using the Requests library.

An example with json response content would be something like:

import requests
r = requests.get('https://github.com/timeline.json')
r.json()

If you look for further information, in the Quickstart section, they have lots of working examples.

EDIT:

For your specific curl translation:

import requests
url = 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere'
payload = open("request.json")
headers = {'content-type': 'application/json', 'Accept-Charset': 'UTF-8'}
r = requests.post(url, data=payload, headers=headers)

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

Updates according iOS7

// If description are available for protocol
protocolDescriptionLabel.text = [dataDictionary objectForKey:@"description"];
[protocolDescriptionLabel sizeToFit];
[protocolDescriptionLabel setLineBreakMode:NSLineBreakByWordWrapping];

CGSize expectedLabelSize = [protocolDescriptionLabel
               textRectForBounds:protocolDescriptionLabel.frame
               limitedToNumberOfLines:protocolDescriptionLabel.numberOfLines].size;
NSLog(@"expectedLabelSize %f", expectedLabelSize.height);

//adjust the label the the new height.
CGRect newFrame = protocolDescriptionLabel.frame;
newFrame.size.height = expectedLabelSize.height;
protocolDescriptionLabel.frame = newFrame;

See Quicksort on wikipedia:

Typically, quicksort is significantly faster in practice than other T(nlogn) algorithms, because its inner loop can be efficiently implemented on most architectures, and in most real-world data, it is possible to make design choices which minimize the probability of requiring quadratic time.

Note that the very low memory requirement is a big plus as well.

You can achieve this by setting content mode of image view to UIViewContentModeScaleAspectFill.

Then use following method method to get the resized uiimage object.

- (UIImage*)setProfileImage:(UIImage *)imageToResize onImageView:(UIImageView *)imageView
{
    CGFloat width = imageToResize.size.width;
    CGFloat height = imageToResize.size.height;
    float scaleFactor;
    if(width > height)
    {
        scaleFactor = imageView.frame.size.height / height;
    }
    else
    {
        scaleFactor = imageView.frame.size.width / width;
    }

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(width * scaleFactor, height * scaleFactor), NO, 0.0);
    [imageToResize drawInRect:CGRectMake(0, 0, width * scaleFactor, height * scaleFactor)];
    UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return resizedImage;
}

Edited Here (Swift Version)

func setProfileImage(imageToResize: UIImage, onImageView: UIImageView) -> UIImage
{
    let width = imageToResize.size.width
    let height = imageToResize.size.height

    var scaleFactor: CGFloat

    if(width > height)
    {
        scaleFactor = onImageView.frame.size.height / height;
    }
    else
    {
        scaleFactor = onImageView.frame.size.width / width;
    }

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(width * scaleFactor, height * scaleFactor), false, 0.0)
    imageToResize.drawInRect(CGRectMake(0, 0, width * scaleFactor, height * scaleFactor))
    let resizedImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return resizedImage;
}

If you set a variable via SETX, you cannot use this variable or its changes immediately. You have to restart the processes that want to use it.

Use the following sequence to directly set it in the setting process too (works for me perfectly in scripts that do some init stuff after setting global variables):

SET XYZ=test
SETX XYZ test

Try this

@Entity

@Table(name="tblperson")

public class Person {

public int id;

public OtherInfo otherInfo;
@Id //Here Id is autogenerated
@Column(name="id")
@GeneratedValue(strategy=GenerationType.AUTO)
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}

@OneToOne(cascade = CascadeType.ALL,targetEntity=OtherInfo.class)
@JoinColumn(name="otherInfo_id") //there should be a column otherInfo_id in Person
public OtherInfo getOtherInfo() {
    return otherInfo;
}
public void setOtherInfo(OtherInfo otherInfo) {
    this.otherInfo= otherInfo;
}
rest of attributes ...
}


@Entity

@Table(name="tblotherInfo")

public class OtherInfo {

private int id;

private Person person;

@Id

@Column(name="id")
@GeneratedValue(strategy=GenerationType.AUTO)
public Long getId() {
    return id;
}
public void setId(Long id) {
    this.id = id;
}

  @OneToOne(mappedBy="OtherInfo",targetEntity=Person.class)   
public College getPerson() {
    return person;
}
public void setPerson(Person person) {
    this.person = person;
}    
 rest of attributes ...
}

Ahah! Checkout the previous commit, then checkout the master.

This problem arises when you have composer installed locally. To make it globally executable,run the below command in terminal

sudo mv composer.phar /usr/local/bin/composer

For CentOS 7 the command is

sudo mv composer.phar /usr/bin/composer

The only way I found which works for me is adding an entry into the "Web Deployment Assembly"

Project webapp > Properties > Deployment Assembly
Add ...
Source : "/target/classes"
Deploy Path : "WEB-INF/classes"

For a single keyword on VARCHAR fields you can use LIKE:

SELECT id, category, location
FROM table
WHERE
(
    category LIKE '%keyword%'
    OR location LIKE '%keyword%'
)

For a description you're usually better adding a full text index and doing a Full-Text Search (MyISAM only):

SELECT id, description
FROM table
WHERE MATCH (description) AGAINST('keyword1 keyword2')

In your Model set:

protected $dates = ['name_field'];

after in your view :

{{ $user->from_date->format('d/m/Y') }}

works

Adding responseType to the request that is made from angular is indeed the solution, but for me it didn't work until I've set responseType to blob, not to arrayBuffer. The code is self explanatory:

    $http({
            method : 'GET',
            url : 'api/paperAttachments/download/' + id,
            responseType: "blob"
        }).then(function successCallback(response) {
            console.log(response);
             var blob = new Blob([response.data]);
             FileSaver.saveAs(blob, getFileNameFromHttpResponse(response));
        }, function errorCallback(response) {   
        });

This will get you count:

get-alias | measure

You can work with the result as with object:

$m = get-alias | measure
$m.Count

And if you would like to have aliases in some variable also, you can use Tee-Object:

$m = get-alias | tee -Variable aliases | measure
$m.Count
$aliases

Some more info on Measure-Object cmdlet is on Technet.

Do not confuse it with Measure-Command cmdlet which is for time measuring. (again on Technet)

This answer is counting that the second parameter is useless when calling removeAttr! (as it was when this answer was posted) Do not use this otherwise!

Can't beat RienNeVaPlus's clean answer, but it does the job as well, it's basically a more compressed way to do the ternary operation:

$('.list-sort')[$('.list-sort').hasAttr('colspan') ? 
    'removeAttr' : 'attr']('colspan', 6);

an extra variable can be used in these cases, when you need to use the reference more than once:

var $listSort = $('.list-sort'); 
$listSort[$listSort.hasAttr('colspan') ? 'removeAttr' : 'attr']('colspan', 6);

I had this issue and what I did and solved the problem was that I used AsEnumerable() just before my Join clause. here is my query:

List<AccountViewModel> selectedAccounts;

 using (ctx = SmallContext.GetInstance()) {
                var data = ctx.Transactions.
                    Include(x => x.Source).
                    Include(x => x.Relation).
                    AsEnumerable().
                    Join(selectedAccounts, x => x.Source.Id, y => y.Id, (x, y) => x).
                    GroupBy(x => new { Id = x.Relation.Id, Name = x.Relation.Name }).
                    ToList();
            }

I was wondering why this issue happens, and now I think It is because after you make a query via LINQ, the result will be in memory and not loaded into objects, I don't know what that state is but they are in in some transitional state I think. Then when you use AsEnumerable() or ToList(), etc, you are placing them into physical memory objects and the issue is resolving.

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

For myself, I would assume unsigned int is platform specific. Integer could be 8 bits, 16 bits, 32 bits or even 64 bits.

DWORD in the other hand, specifies its own size, which is Double Word. Word are 16 bits so DWORD will be known as 32 bit across all platform

If you are building a client with Resttemplate, you can only set the endpoint like this: https://IP/path_to_service and set the requestFactory.
With this solution you don't need to RESTART your TOMCAT or Apache:

public static HttpComponentsClientHttpRequestFactory requestFactory(CloseableHttpClient httpClient) {
    TrustStrategy acceptingTrustStrategy = new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            return true;
        }
    };

    SSLContext sslContext = null;
    try {
        sslContext = org.apache.http.ssl.SSLContexts.custom()
                .loadTrustMaterial(null, acceptingTrustStrategy)
                .build();
    } catch (Exception e) {
        logger.error(e.getMessage(), e);
    }   

    HostnameVerifier hostnameVerifier = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    final SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext,hostnameVerifier);

    final Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
            .register("http", new PlainConnectionSocketFactory())
            .register("https", csf)
            .build();

    final PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
    cm.setMaxTotal(100);
    httpClient = HttpClients.custom()
            .setSSLSocketFactory(csf)
            .setConnectionManager(cm)
            .build();

    HttpComponentsClientHttpRequestFactory requestFactory =
            new HttpComponentsClientHttpRequestFactory();

    requestFactory.setHttpClient(httpClient);

    return requestFactory;
}

You don't have a validator on the page. Add something like this to show the validation message.

@Html.ValidationMessageFor(model => model.PhoneNumber, "", new { @class = "text-danger" })

There's no built-in command for that because it's illegal. You can't modify the size of an array once declared.

What you're looking for is either std::vector to simulate a dynamic array, or better yet a std::string.

std::string first ("The dog jumps ");
std::string second ("over the log");
std::cout << first + second << std::endl;

This answer is based on the ones provided by @Sasan and @CAD bloke.

If you wish to use this in .NET Standard 2 or don't want Newtonsoft, see Xaniff's answer below

Works only with EF Core 2.1+ (not .NET Standard compatible)(Newtonsoft JsonConvert)

builder.Entity<YourEntity>().Property(p => p.Strings)
    .HasConversion(
        v => JsonConvert.SerializeObject(v),
        v => JsonConvert.DeserializeObject<List<string>>(v));

Using the EF Core fluent configuration we serialize/deserialize the List to/from JSON.

Why this code is the perfect mix of everything you could strive for:

• The problem with Sasn's original answer is that it will turn into a big mess if the strings in the list contains commas (or any character chosen as the delimiter) because it will turn a single entry into multiple entries but it is the easiest to read and most concise.
• The problem with CAD bloke's answer is that it is ugly and requires the model to be altered which is a bad design practice (see Marcell Toth's comment on Sasan's answer). But it is the only answer that is data-safe.

DELETE FROM table WHERE date < '2011-09-21 08:21:22';

You have two way for your question :

1- Use Update Command in your Trigger.

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS BEGIN
    SET NOCOUNT ON;
    IF UPDATE (QtyToRepair) 
    BEGIN
        UPDATE SCHEDULE 
        SET modified = GETDATE()
           , ModifiedUser = SUSER_NAME()
           , ModifiedHost = HOST_NAME()
        FROM SCHEDULE S INNER JOIN Inserted I 
        ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
        WHERE S.QtyToRepair <> I.QtyToRepair
    END 
END

2- Use Join between Inserted table and deleted table

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS BEGIN
    SET NOCOUNT ON;    

    UPDATE SCHEDULE 
    SET modified = GETDATE()
       , ModifiedUser = SUSER_NAME()
       , ModifiedHost = HOST_NAME()
    FROM SCHEDULE S 
    INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
    INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber                  
    WHERE S.QtyToRepair <> I.QtyToRepair
    AND D.QtyToRepair <> I.QtyToRepair
END

When you use update command for table SCHEDULE and Set QtyToRepair Column to new value, if new value equal to old value in one or multi row, solution 1 update all updated row in Schedule table but solution 2 update only schedule rows that old value not equal to new value.

You can't use variable names to bind columns or other system objects, you need dynamic sql

DECLARE @value varchar(10)  
SET @value = 'intStep'  
DECLARE @sqlText nvarchar(1000); 

SET @sqlText = N'SELECT ' + @value + ' FROM dbo.tblBatchDetail'
Exec (@sqlText)

simple way :

   -(void) viewDidLoad {
   self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage       imageNamed:@"background.png"]];
    [super viewDidLoad];
    }

To make everything writable by the owner, read/execute by the group, and world executable:

chmod -R 0755

To make everything wide open:

chmod -R 0777

Here's an example of how you would accomplish such a task:

#import <Foundation/Foundation.h>
typedef int (^IntBlock)();

@interface myobj : NSObject
{
    IntBlock compare;
}

@property(readwrite, copy) IntBlock compare;

@end

@implementation myobj

@synthesize compare;

- (void)dealloc 
{
   // need to release the block since the property was declared copy. (for heap
   // allocated blocks this prevents a potential leak, for compiler-optimized 
   // stack blocks it is a no-op)
   // Note that for ARC, this is unnecessary, as with all properties, the memory management is handled for you.
   [compare release];
   [super dealloc];
}
@end

int main () {
    @autoreleasepool {
        myobj *ob = [[myobj alloc] init];
        ob.compare = ^
        {
            return rand();
        };
        NSLog(@"%i", ob.compare());
        // if not ARC
        [ob release];
    }

    return 0;
}

Now, the only thing that would need to change if you needed to change the type of compare would be the typedef int (^IntBlock)(). If you need to pass two objects to it, change it to this: typedef int (^IntBlock)(id, id), and change your block to:

^ (id obj1, id obj2)
{
    return rand();
};

I hope this helps.

EDIT March 12, 2012:

For ARC, there are no specific changes required, as ARC will manage the blocks for you as long as they are defined as copy. You do not need to set the property to nil in your destructor, either.

Revised Answer

If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:

var myname varchar2(20);

exec :myname := 'Tom';

SELECT *
FROM   Customers
WHERE  Name = :myname;

In many tools (such as Toad and SQL Developer), omitting the var and exec statements will cause the program to prompt you for the value.

Original Answer

A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT (roughly equivalent to print) to output the variable:

DECLARE
   myname varchar2(20);
BEGIN
     myname := 'Tom';

     dbms_output.print_line(myname);
END;

This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:

CREATE FUNCTION my_function (myname in varchar2)
     my_refcursor out sys_refcursor
BEGIN
     open my_refcursor for
     SELECT *
     FROM   Customers
     WHERE  Name = myname;

     return my_refcursor;
END my_function;

List<T> TheList = new List<T>();

TheList.FindAll(element => element.Satisfies(Condition)).ForEach(element => TheList.Remove(element));

Try adding C:\Program Files\Nodejs to your PATH environment variable. The PATH environment variable allows run executables or access files within the folders specified (separated by semicolons).

On the command prompt, the command would be set PATH=%PATH%;C:\Program Files\Nodejs.

My understanding is that this question is better answered over in this post.

But briefly, the answer to the OP with this method is simply:

s1 = pd.merge(df1, df2, how='inner', on=['user_id'])

Which gives s1 with 5 columns: user_id and the other two columns from each of df1 and df2.

Extension method should be inside a static class. So please add your extension method inside a static class.

so for example it should be like this

public static class myclass
    {
        public static Byte[] ToByteArray(this Stream stream)
        {
            Int32 length = stream.Length > Int32.MaxValue ? Int32.MaxValue : Convert.ToInt32(stream.Length);
            Byte[] buffer = new Byte[length];
            stream.Read(buffer, 0, length);
            return buffer;
        }

    }

You can use a position: absolute inside a position: relative

https://codepen.io/Iquixe/pen/RwRzGrM

The RelativeLayout (i.e. the ViewParent) should have a resource Id defined in the layout file (for example, android:id=@+id/myParentViewId). If you don't do that, the call to getId will return null. Look at this answer for more info.

You don't need JQuery, you can do it in JavaScript, Hope you get it.

If you don't have a .gitignore file. You can create a new one by

touch .gitignore

And you can exclude a folder by entering the below command in the .gitignore file

/folderName

push this file into your git repository so that when a new person clone your project he don't have to add the same again

If you are running in Windows you can use the following command.

cd "Script location"
schtasks /run /tn "TASK1"
schtasks /run /tn "TASK2"

exit

I ran into same issue but updating wrong jre on my linux machine. It is highly likely that tomcat is using different jre and your cli prompt is configured to use a different jre.

Make sure you are picking up the correct jre.

Step #1:

ps -ef | grep tomcat

You will see some thing like:

root     29855     1  3 17:54 pts/3    00:00:42 /usr/java/jdk1.7.0_79/jre/bin/java 

Now use this:

keytool -import -alias example -keystore  /usr/java/jdk1.7.0_79/jre/lib/security/cacerts -file cert.cer
PWD: changeit

*.cer file can be geneated as shown below: (or you can use your own)

openssl x509 -in cert.pem -outform pem -outform der -out cert.cer

Here is an optimized version of the above method RemoveInvalidXmlChars which doesn't create a new array on every call, thus stressing the GC unnecessarily:

public static string RemoveInvalidXmlChars(string text)
{
    if (text == null)
        return text;
    if (text.Length == 0)
        return text;

    // a bit complicated, but avoids memory usage if not necessary
    StringBuilder result = null;
    for (int i = 0; i < text.Length; i++)
    {
        var ch = text[i];
        if (XmlConvert.IsXmlChar(ch))
        {
            result?.Append(ch);
        }
        else if (result == null)
        {
            result = new StringBuilder();
            result.Append(text.Substring(0, i));
        }
    }

    if (result == null)
        return text; // no invalid xml chars detected - return original text
    else
        return result.ToString();

}

See my article on understanding vertical alignment. There are multiple techniques to accomplish what you want at the end of the discussion.

(Super-short summary: either set the line-height of the child equal to the height of the container, or set positioning on the container and absolutely position the child at top:50% with margin-top:-YYYpx, YYY being half the known height of the child.)

Actually there is. There is a static method valueOf in the java.sql.Date object which does exactly that. So we have

java.util.Date date = java.sql.Date.valueOf(localDate);

and that's it. No explicit setting of time zones because the local time zone is taken implicitly.

From docs:

The provided LocalDate is interpreted as the local date in the local time zone.

The java.sql.Date subclasses java.util.Date so the result is a java.util.Date also.

And for the reverse operation there is a toLocalDate method in the java.sql.Date class. So we have:

LocalDate ld = new java.sql.Date(date.getTime()).toLocalDate();

I think Regex is the most flexible and solid way:

var str = "This is my string"
let regex = try! NSRegularExpression(pattern: " ", options: [])
let output = regex.stringByReplacingMatchesInString(
    str,
    options: [],
    range: NSRange(location: 0, length: str.characters.count),
    withTemplate: "+"
)
// output: "This+is+my+string"

If you want to get the exact date of another commit (say you rebase edited a commit and want it to have the date of the original pre-rebase version):

git commit --amend --date="$(git show -s --format=%ai a383243)"

This corrects the date of the HEAD commit to be exactly the date of commit a383243 (include more digits if there are ambiguities). It will also pop up an editor window so you can edit the commit message.

That's for the author date which is what you care for usually - see other answers for the committer date.

import re
word = 'fubar'
regexp = re.compile(r'ba[rzd]')
if regexp.search(word):
  print 'matched'

Here's a way to do it without formulas or macros:

1. Save your CSV as Excel
2. Select any cells that might have commas
3. Open to the Format menu and click on Cells
4. Pick the Custom format
5. Enter this => \"@\"
6. Click OK
7. Save the file as CSV

(from http://www.lenashore.com/2012/04/how-to-add-quotes-to-your-cells-in-excel-automatically/)

In x0n's example, it should be:

SET ROWCOUNT @top

SELECT * from sometable

SET ROWCOUNT 0

With:

FILES = $(shell ls)

indented underneath all like that, it's a build command. So this expands $(shell ls), then tries to run the command FILES ....

If FILES is supposed to be a make variable, these variables need to be assigned outside the recipe portion, e.g.:

FILES = $(shell ls)
all:
        echo $(FILES)

Of course, that means that FILES will be set to "output from ls" before running any of the commands that create the .tgz files. (Though as Kaz notes the variable is re-expanded each time, so eventually it will include the .tgz files; some make variants have FILES := ... to avoid this, for efficiency and/or correctness.¹)

If FILES is supposed to be a shell variable, you can set it but you need to do it in shell-ese, with no spaces, and quoted:

all:
        FILES="$(shell ls)"

However, each line is run by a separate shell, so this variable will not survive to the next line, so you must then use it immediately:

        FILES="$(shell ls)"; echo $$FILES

This is all a bit silly since the shell will expand * (and other shell glob expressions) for you in the first place, so you can just:

        echo *

as your shell command.

Finally, as a general rule (not really applicable to this example): as esperanto notes in comments, using the output from ls is not completely reliable (some details depend on file names and sometimes even the version of ls; some versions of ls attempt to sanitize output in some cases). Thus, as l0b0 and idelic note, if you're using GNU make you can use $(wildcard) and $(subst ...) to accomplish everything inside make itself (avoiding any "weird characters in file name" issues). (In sh scripts, including the recipe portion of makefiles, another method is to use find ... -print0 | xargs -0 to avoid tripping over blanks, newlines, control characters, and so on.)

¹The GNU Make documentation notes further that POSIX make added ::= assignment in 2012. I have not found a quick reference link to a POSIX document for this, nor do I know off-hand which make variants support ::= assignment, although GNU make does today, with the same meaning as :=, i.e., do the assignment right now with expansion.

Note that VAR := $(shell command args...) can also be spelled VAR != command args... in several make variants, including all modern GNU and BSD variants as far as I know. These other variants do not have $(shell) so using VAR != command args... is superior in both being shorter and working in more variants.

If you just want to see all the columns you can do something of this sort as a quick fix

cols = data_all2.columns

now cols will behave as a iterative variable that can be indexed. for example

cols[11:20]

Using --porcelain gives a backwards-compatible output easy to parse:

git status --branch --porcelain | grep '##' | cut -c 4-

From the documentation:

The porcelain format is similar to the short format, but is guaranteed not to change in a backwards-incompatible way between Git versions or based on user configuration. This makes it ideal for parsing by scripts.

In case you want an awk-only solution without creating a temporary file and usable with version!=(gawk 4.1.0):

awk '{a[b++]=$0} END {for(c=0;c<=b;c++)print a[c]>ARGV[1]}' file

Considering that an include statment in php at the most basic level takes the code from a file and pastes it into where you called it and the fact that the manual on include states the following:

When a file is included, the code it contains inherits the variable scope of the line on which the include occurs. Any variables available at that line in the calling file will be available within the called file, from that point forward.

These things make me think that there is a diffrent problem alltogether. Also Option number 3 will never work because you're not redirecting to second.php you're just including it and option number 2 is just a weird work around. The most basic example of the include statment in php is:

vars.php
<?php

$color = 'green';
$fruit = 'apple';

?>

test.php
<?php

echo "A $color $fruit"; // A

include 'vars.php';

echo "A $color $fruit"; // A green apple

?>

Considering that option number one is the closest to this example (even though more complicated then it should be) and it's not working, its making me think that you made a mistake in the include statement (the wrong path relative to the root or a similar issue).

Your vector<string> userString has size 0, so the loop is never entered. You could start with a vector of a given size:

vector<string> userString(10);      
string word;        
string sentence;           
for (decltype(userString.size()) i = 0; i < userString.size(); ++i)
{
    cin >> word;
    userString[i] = word;
    sentence += userString[i] + " ";
}

although it is not clear why you need the vector at all:

string word;        
string sentence;           
for (int i = 0; i < 10; ++i)
{
    cin >> word;
    sentence += word + " ";
}

If you don't want to have a fixed limit on the number of input words, you can use std::getline in a while loop, checking against a certain input, e.g. "q":

while (std::getline(std::cin, word) && word != "q")
{
    sentence += word + " ";
}

This will add words to sentence until you type "q".

I know it really late for another answer but I just wanted to share what helped me at the end. It will also load resources/files from the absolute path of the file system (not only the classpath's).

public class ResourceLoader {

    public static URL getResource(String resource) {
        final List<ClassLoader> classLoaders = new ArrayList<ClassLoader>();
        classLoaders.add(Thread.currentThread().getContextClassLoader());
        classLoaders.add(ResourceLoader.class.getClassLoader());

        for (ClassLoader classLoader : classLoaders) {
            final URL url = getResourceWith(classLoader, resource);
            if (url != null) {
                return url;
            }
        }

        final URL systemResource = ClassLoader.getSystemResource(resource);
        if (systemResource != null) {
            return systemResource;
        } else {
            try {
                return new File(resource).toURI().toURL();
            } catch (MalformedURLException e) {
                return null;
            }
        }
    }

    private static URL getResourceWith(ClassLoader classLoader, String resource) {
        if (classLoader != null) {
            return classLoader.getResource(resource);
        }
        return null;
    }

}

For everybody who codes Java for Android devices and ends up here: use SparseArray for better performance;

private final SparseArray<myObject> myMap = new SparseArray<myObject>();

with this you can use int instead of Integer like;

int newPos = 3;

myMap.put(newPos, newObject);
myMap.get(newPos);

You would have to overwrite the CSS rule:

.navbar-inverse .brand, .navbar-inverse .nav > li > a

or

.navbar .brand, .navbar .nav > li > a 

depending if you are using the dark or light theme, respectively. To do this, add a CSS with your overwritten rules and make sure it comes in your HTML after the Bootstrap CSS. For example:

.navbar .brand, .navbar .nav > li > a {
    color: #D64848;
}
.navbar .brand, .navbar .nav > li > a:hover {
    color: #F56E6E;
}

There is also the alternative where you customize your own Boostrap here. In this case, in the Navbar section, you have the @navbarLinkColor.

What to change? Aside from the 3 or 4 dimensional array problem, you should get rid of the magic numbers (10 and 9).

const int DIM_SIZE = 10;
int myArray[DIM_SIZE][DIM_SIZE][DIM_SIZE];

for (int i = 0; i < DIM_SIZE; ++i){
    for (int t = 0; t < DIM_SIZE; ++t){            
        for (int x = 0; x < DIM_SIZE; ++x){

I'm not sure what you want, but i'll use lattice.

x = rep(x,2)
y = c(y1,y2)
fac.data = as.factor(rep(1:2,each=5))
df = data.frame(x=x,y=y,z=fac.data)
# this create a data frame where I have a factor variable, z, that tells me which data I have (y1 or y2)

Then, just plot

xyplot(y ~x|z, df)
# or maybe
xyplot(x ~y|z, df)

I guess you are working with a Dynamic Web Project, because you mentioned de folder WEB-INF/lib in a comment; if yes, make sure your not putting any *-servlet jar file inside this folder or other jar already provided by the container, in this case Tomcat. Plus: Once I used jersey-servlet.jar, and I needed to remove it from the lib folder in order to Tomcat start without problems; then I use just jersey-bundle.jar and it works well.

You can also use this free plug-and-play extension:

http://www.magentocommerce.com/magento-connect/manage-customer-account-menu.html

This extension does not touch any of the Magento core files.

With this extension you are able to:

1. Decide per menu item to show or hide it with one click in the Magento backend.
2. Rename menu items easily.

How about just:

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(20, 20, 280, 32)];
textField.borderStyle = UITextBorderStyleRoundedRect;
[self addSubview:textField];

Using:

works but it gives me another error, see new question

A stored procedure is a named collection of SQL statements and procedural logic i.e, compiled, verified and stored in the server database. A stored procedure is typically treated like other database objects and controlled through server security mechanism.

For users of SQL 2000, the actual command that will provide this information is:

select c.text
from sysobjects     o
join syscomments    c on c.id = o.id
where o.name = '<view_name_here>'
  and o.type      = 'V'

• A compiler reads, analyses and translates code into either an object file or a list of error messages.
• A linker combines one or more object files and possible some library code into either some executable, some library or a list of error messages.
• A loader reads the executable code into memory, does some address translation and tries to run the program resulting in a running program or an error message (or both).

adbd has a compilation flag/option to enable root access: ALLOW_ADBD_ROOT=1.

Up to Android 9: If adbd on your device is compiled without that flag, it will always drop privileges when starting up and thus "adb root" will not help at all. I had to patch the calls to setuid(), setgid(), setgroups() and the capability drops out of the binary myself to get a permanently rooted adbd on my ebook reader.

With Android 10 this changed; when the phone/tablet is unlocked (ro.boot.verifiedbootstate == "orange"), then adb root mode is possible in any case.

You can't move the mouse pointer using javascript, and thus for obvious security reasons. The best way to achieve this effect would be to actually place the control under the mouse pointer.

#vi function.sh

#!/bin/bash
f1() {
    echo "Hello $name"
}

f2() {
    echo "Enter your name: "
    read name
    f1
}
f2

#sh function.sh

Here function f2 will call function f1

1. Right click on the project file -> Add -> New Item -> Application Configuration File. This will add an app.config (or web.config) file to your project.

2. The ConfigurationManager class would be a good start. You can use it to read different configuration values from the configuration file.

I suggest you start reading the MSDN document about Configuration Files.

cat(capture.output(print(my.list), file="test.txt"))

from R: Export and import a list to .txt file https://stackoverflow.com/users/1855677/42 is the only thing that worked for me. This outputs the list of lists as it is in the text file

To expand on Cruz Nunez code and add continual formatting, plus include some international phone number formats.

    $('#phone').on('input', function() {
      var number = $(this).val().replace(/[^\d]/g, '');
      if (number.length == 3) {
        number = number.replace(/(\d{3})/, "$1-");
      } else if (number.length == 4) {
        number = number.replace(/(\d{3})(\d{1})/, "$1-$2");
      } else if (number.length == 5) {
        number = number.replace(/(\d{3})(\d{2})/, "$1-$2");
      } else if (number.length == 6) {
        number = number.replace(/(\d{3})(\d{3})/, "$1-$2-");
      } else if (number.length == 7) {
        number = number.replace(/(\d{3})(\d{3})(\d{1})/, "$1-$2-$3");
      } else if (number.length == 8) {
        number = number.replace(/(\d{4})(\d{4})/, "$1-$2");
      } else if (number.length == 9) {
        number = number.replace(/(\d{3})(\d{3})(\d{3})/, "$1-$2-$3");
      } else if (number.length == 10) {
        number = number.replace(/(\d{3})(\d{3})(\d{4})/, "$1-$2-$3");
      } else if (number.length == 11) {
        number = number.replace(/(\d{1})(\d{3})(\d{3})(\d{4})/, "$1-$2-$3-$4");
      } else if (number.length == 12) {
        number = number.replace(/(\d{2})(\d{3})(\d{3})(\d{4})/, "$1-$2-$3-$4");
      }
      $(this).val(number);
    });

You could use setInterval for this.

<script type="text/javascript">
function myFunction () {
    console.log('Executed!');
}

var interval = setInterval(function () { myFunction(); }, 60000);
</script>

Disable the timer by setting clearInterval(interval).

It can easily be done if u had declared a class that extends from Application

This class will be like a singleton, so when u need a context u can get it just like this:

I think this is the better answer and the cleaner

Here is my code from Utilities package:

 public static String getAppNAme(){
     return MyOwnApplication.getInstance().getString(R.string.app_name);
 }

May be easier using a java.util.HashSet. For example:

  List <String> list = new ArrayList<String>(); 
  list.add("behold");
  list.add("bend");
  list.add("bet");

  //Load the list into a hashSet
  Set<String> set = new HashSet<String>(list);
  if (set.contains("bend"))
  {
    System.out.println("String found!");
  }

Using % you will run into a hex operation error when the time value is 7-9. To avoid this, use DelayedExpansion and grab time values with !min:~1!

An alternate method, if you have PowerShell is to call that:

for /F "usebackq delims=Z" %%i IN (`powershell Get-Date -format u`) do (set server-time=%%i)

HTML 5 invites you give add a lot of semantic value to your code. What's more, there are natives solution to embed multimedia content.

The rest is important, but it's more technical sugar that will save you from doing the same stuff with a client programming language.

For modern JS, use event.key!

document.addEventListener("keypress", function onPress(event) {
    if (event.key === "z" && event.ctrlKey) {
        // Do something awesome
    }
});

NOTE: The old properties (.keyCode and .which) are Deprecated.

Make sure that your Spring form mentions the modelAttribute="<Model Name".

Example:

@Controller
@RequestMapping("/greeting.html")
public class GreetingController {

 @ModelAttribute("greeting")
 public Greeting getGreetingObject() {
  return new Greeting();
 }

 /**
  * GET
  * 
  * 
  */
 @RequestMapping(method = RequestMethod.GET)
 public String handleRequest() {
  return "greeting";
 }

 /**
  * POST
  * 
  *

 @RequestMapping(method = RequestMethod.POST)
 public ModelAndView processSubmit(@ModelAttribute("greeting") Greeting greeting, BindingResult result){
  ModelAndView mv = new ModelAndView();
  mv.addObject("greeting", greeting);  
  return mv;
 }
}

In your JSP :

<form:form  modelAttribute="greeting" method="POST" action="greeting.html">

JSON (JavaScript Object Notation) is a lightweight format that is used for data interchanging. It is based on a subset of JavaScript language (the way objects are built in JavaScript). As stated in the MDN, some JavaScript is not JSON, and some JSON is not JavaScript.

An example of where this is used is web services responses. In the 'old' days, web services used XML as their primary data format for transmitting back data, but since JSON appeared (The JSON format is specified in RFC 4627 by Douglas Crockford), it has been the preferred format because it is much more lightweight

You can find a lot more info on the official JSON web site.

JSON is built on two structures:

• A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
• An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.

JSON Structure

Here is an example of JSON data:

{
     "firstName": "John",
     "lastName": "Smith",
     "address": {
         "streetAddress": "21 2nd Street",
         "city": "New York",
         "state": "NY",
         "postalCode": 10021
     },
     "phoneNumbers": [
         "212 555-1234",
         "646 555-4567"
     ]
 }

JSON in JavaScript

JSON (in Javascript) is a string!

People often assume all Javascript objects are JSON and that JSON is a Javascript object. This is incorrect.

In Javascript var x = {x:y} is not JSON, this is a Javascript object. The two are not the same thing. The JSON equivalent (represented in the Javascript language) would be var x = '{"x":"y"}'. x is an object of type string not an object in it's own right. To turn this into a fully fledged Javascript object you must first parse it, var x = JSON.parse('{"x":"y"}');, x is now an object but this is not JSON anymore.

See Javascript object Vs JSON

When working with JSON and JavaScript, you may be tempted to use the eval function to evaluate the result returned in the callback, but this is not suggested since there are two characters (U+2028 & U+2029) valid in JSON but not in JavaScript (read more of this here).

Therefore, one must always try to use Crockford's script that checks for a valid JSON before evaluating it. Link to the script explanation is found here and here is a direct link to the js file. Every major browser nowadays has its own implementation for this.

Example on how to use the JSON parser (with the json from the above code snippet):

//The callback function that will be executed once data is received from the server
var callback = function (result) {
    var johnny = JSON.parse(result);
    //Now, the variable 'johnny' is an object that contains all of the properties 
    //from the above code snippet (the json example)
    alert(johnny.firstName + ' ' + johnny.lastName); //Will alert 'John Smith'
};

The JSON parser also offers another very useful method, stringify. This method accepts a JavaScript object as a parameter, and outputs back a string with JSON format. This is useful for when you want to send data back to the server:

var anObject = {name: "Andreas", surname : "Grech", age : 20};
var jsonFormat = JSON.stringify(anObject);
//The above method will output this: {"name":"Andreas","surname":"Grech","age":20}

The above two methods (parse and stringify) also take a second parameter, which is a function that will be called for every key and value at every level of the final result, and each value will be replaced by result of your inputted function. (More on this here)

Btw, for all of you out there who think JSON is just for JavaScript, check out this post that explains and confirms otherwise.

You should be able to rebase your branch on master:

git checkout feature1
git rebase master

Manage all conflicts that arise. When you get to the commits with the bugfixes (already in master), Git will say that there were no changes and that maybe they were already applied. You then continue the rebase (while skipping the commits already in master) with

git rebase --skip

If you perform a git log on your feature branch, you'll see the bugfix commit appear only once, and in the master portion.

For a more detailed discussion, take a look at the Git book documentation on git rebase (https://git-scm.com/docs/git-rebase) which cover this exact use case.

================ Edit for additional context ====================

This answer was provided specifically for the question asked by @theomega, taking his particular situation into account. Note this part:

I want to prevent [...] commits on my feature branch which have no relation to the feature implementation.

Rebasing his private branch on master is exactly what will yield that result. In contrast, merging master into his branch would precisely do what he specifically does not want to happen: adding a commit that is not related to the feature implementation he is working on via his branch.

To address the users that read the question title, skip over the actual content and context of the question, and then only read the top answer blindly assuming it will always apply to their (different) use case, allow me to elaborate:

• only rebase private branches (i.e. that only exist in your local repository and haven't been shared with others). Rebasing shared branches would "break" the copies other people may have.
• if you want to integrate changes from a branch (whether it's master or another branch) into a branch that is public (e.g. you've pushed the branch to open a pull request, but there are now conflicts with master, and you need to update your branch to resolve those conflicts) you'll need to merge them in (e.g. with git merge master as in @Sven's answer).
• you can also merge branches into your local private branches if that's your preference, but be aware that it will result in "foreign" commits in your branch.

Finally, if you're unhappy with the fact that this answer is not the best fit for your situation even though it was for @theomega, adding a comment below won't be particularly helpful: I don't control which answer is selected, only @theomega does.

Usually (same as I do in mysql/postgres) I stores dates in int(mysql/post) or text(sqlite) to store them in the timestamp format.

Then I will convert them into Date objects and perform actions based on user TimeZone

The Best and easy way to upload data / import data into Google colab GUI way is click on left most 3rd option File menu icon and there you will get upload browser files as you get in windows OS .Check below the images for better easy understanding.After clicking on below two options you will get upload window box easy. work done.

from google.colab import files
files=files.upload()

Ok, so the easiest method to create several plots is this:

import matplotlib.pyplot as plt
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
for i in range(len(x)):
    plt.figure()
    plt.plot(x[i],y[i])
    # Show/save figure as desired.
    plt.show()
# Can show all four figures at once by calling plt.show() here, outside the loop.
#plt.show()

Note that you need to create a figure every time or pyplot will plot in the first one created.

If you want to create several data series all you need to do is:

import matplotlib.pyplot as plt
plt.figure()
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[2,3,4,5],[3,4,5,6],[7,8,9,10]]
plt.plot(x[0],y[0],'r',x[1],y[1],'g',x[2],y[2],'b',x[3],y[3],'k')

You could automate it by having a list of colours like ['r','g','b','k'] and then just calling both entries in this list and corresponding data to be plotted in a loop if you wanted to. If you just want to programmatically add data series to one plot something like this will do it (no new figure is created each time so everything is plotted in the same figure):

import matplotlib.pyplot as plt
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[2,3,4,5],[3,4,5,6],[7,8,9,10]]
colours=['r','g','b','k']
plt.figure() # In this example, all the plots will be in one figure.    
for i in range(len(x)):
    plt.plot(x[i],y[i],colours[i])
plt.show()

Hope this helps. If anything matplotlib has a very good documentation page with plenty of examples.

17 Dec 2019: added plt.show() and plt.figure() calls to clarify this part of the story.

Running 'py' command will tell you what version you have running. If you currently running 3.x and you need to switch to 2.x, you will need to use switch '-2'

py -2

If you need to switch from python 2.x to python 3.x you will have to use '-3' switch

py -3

If you would like to have Python 3.x as a default version, then you will need to create environment variable 'PY_PYTHON' and set it's value to 3.

My issue on OSX it was gradle version. Gradle was ignoring my Android.mk. So, in order to override this option, and use my make instead, I have entered this line:

sourceSets.main.jni.srcDirs = []

inside of the android tag in build.gradle.

I have wasted lot of time on this!

A .zip file is required in order to include npm modules in Lambda. And you really shouldn't be using the Lambda web editor for much of anything- as with any production code, you should be developing locally, committing to git, etc.

MY FLOW:

1) My Lambda functions are usually helper utilities for a larger project, so I create a /aws/lambdas directory within that to house them.

2) Each individual lambda directory contains an index.js file containing the function code, a package.json file defining dependencies, and a /node_modules subdirectory. (The package.json file is not used by Lambda, it's just so we can locally run the npm install command.)

package.json:

{
  "name": "my_lambda",
  "dependencies": {
    "svg2png": "^4.1.1"
  }
}

3) I .gitignore all node_modules directories and .zip files so that the files generated from npm installs and zipping won't clutter our repo.

.gitignore:

# Ignore node_modules
**/node_modules

# Ignore any zip files
*.zip

4) I run npm install from within the directory to install modules, and develop/test the function locally.

5) I .zip the lambda directory and upload it via the console.

(IMPORTANT: Do not use Mac's 'compress' utility from Finder to zip the file! You must run zip from the CLI from within the root of the directory- see here)

zip -r ../yourfilename.zip * 

NOTE:

You might run into problems if you install the node modules locally on your Mac, as some platform-specific modules may fail when deployed to Lambda's Linux-based environment. (See https://stackoverflow.com/a/29994851/165673)

The solution is to compile the modules on an EC2 instance launched from the AMI that corresponds with the Lambda Node.js runtime you're using (See this list of Lambda runtimes and their respective AMIs).

See also AWS Lambda Deployment Package in Node.js - AWS Lambda

You can also do this

[Flags]
public enum MyEnum
{
    None   = 0,
    First  = 1 << 0,
    Second = 1 << 1,
    Third  = 1 << 2,
    Fourth = 1 << 3
}

I find the bit-shifting easier than typing 4,8,16,32 and so on. It has no impact on your code because it's all done at compile time

Provided that your int column is nullable, you may write:

UPDATE dbo.TableName
SET TableName.IntColumn = NULL
WHERE <condition>

The question has already been marked as answered, But I guess the question states that the person wants to remove multiple columns from a DataTable.

So for that, here is what I did, when I came across the same problem.

string[] ColumnsToBeDeleted = { "col1", "col2", "col3", "col4" };

foreach (string ColName in ColumnsToBeDeleted)
{
    if (dt.Columns.Contains(ColName))
        dt.Columns.Remove(ColName);
}

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

Omar's solution is decent* if you cannot upgrade your environment to .NET 4.5 in order to gain access to the async and await APIs. That said, there here is one important change that should be made in order to avoid poor performance. A slight delay should be added between calls to Application.DoEvents() in order to prevent excessive CPU usage. By adding

Thread.Sleep(1);

before the call to Application.DoEvents(), you can add such a delay (1 millisecond) and prevent the application from using all of the cpu cycles available to it.

private void WaitNSeconds(int seconds)
{
    if (seconds < 1) return;
    DateTime _desired = DateTime.Now.AddSeconds(seconds);
    while (DateTime.Now < _desired) {
         Thread.Sleep(1);
         System.Windows.Forms.Application.DoEvents();
    }
}

*See https://blog.codinghorror.com/is-doevents-evil/ for a more detailed discussion on the potential pitfalls of using Application.DoEvents().

(I am using Android Studio 3.0.1)

1. I downloaded "SDK Platform-Tools" from https://developer.android.com/studio/releases/platform-tools
2. Copied 'adb.exe' to C:\Users\user\AppData\Local\Android\Sdk\platform-tools.
3. Then I got no errors when running the app.
4. I also added C:\Users\user\AppData\Local\Android\Sdk\platform-tools\adb.exe to the exception list of my anti-virus tool

You need to do this:

OleDbConnection connection = new OleDbConnection(
    "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet DS = new DataSet();
connection.Open();

string query = 
    @"SELECT tbl_Computer.*,  tbl_Besitzer.*
    FROM tbl_Computer 
    INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
    WHERE (((tbl_Besitzer.Vorname)='ma'))";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection); 
DBAdapter.Fill(DS);

By the way, what is this DataSet1? This should be "DataSet".

what i feel like we could use:

import os
import signal
import subprocess
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)

os.killpg(os.getpgid(pro.pid), signal.SIGINT)

this will not kill all your task but the process with the p.pid

Minimal runnable multi-file scope example

Here I illustrate how static affects the scope of function definitions across multiple files.

a.c

#include <stdio.h>

/* Undefined behavior: already defined in main.
 * Binutils 2.24 gives an error and refuses to link.
 * https://stackoverflow.com/questions/27667277/why-does-borland-compile-with-multiple-definitions-of-same-object-in-different-c
 */
/*void f() { puts("a f"); }*/

/* OK: only declared, not defined. Will use the one in main. */
void f(void);

/* OK: only visible to this file. */
static void sf() { puts("a sf"); }

void a() {
    f();
    sf();
}

main.c

#include <stdio.h>

void a(void);        

void f() { puts("main f"); }

static void sf() { puts("main sf"); }

void m() {
    f();
    sf();
}

int main() {
    m();
    a();
    return 0;
}

GitHub upstream.

Compile and run:

gcc -c a.c -o a.o
gcc -c main.c -o main.o
gcc -o main main.o a.o
./main

Output:

main f
main sf
main f
a sf

Interpretation

• there are two separate functions sf, one for each file
• there is a single shared function f

As usual, the smaller the scope, the better, so always declare functions static if you can.

In C programming, files are often used to represent "classes", and static functions represent "private" methods of the class.

A common C pattern is to pass a this struct around as the first "method" argument, which is basically what C++ does under the hood.

What standards say about it

C99 N1256 draft 6.7.1 "Storage-class specifiers" says that static is a "storage-class specifier".

6.2.2/3 "Linkages of identifiers" says static implies internal linkage:

If the declaration of a file scope identifier for an object or a function contains the storage-class specifier static, the identifier has internal linkage.

and 6.2.2/2 says that internal linkage behaves like in our example:

In the set of translation units and libraries that constitutes an entire program, each declaration of a particular identifier with external linkage denotes the same object or function. Within one translation unit, each declaration of an identifier with internal linkage denotes the same object or function.

where "translation unit" is a source file after preprocessing.

How GCC implements it for ELF (Linux)?

With the STB_LOCAL binding.

If we compile:

int f() { return 0; }
static int sf() { return 0; }

and disassemble the symbol table with:

readelf -s main.o

the output contains:

Num:    Value          Size Type    Bind   Vis      Ndx Name
  5: 000000000000000b    11 FUNC    LOCAL  DEFAULT    1 sf
  9: 0000000000000000    11 FUNC    GLOBAL DEFAULT    1 f

so the binding is the only significant difference between them. Value is just their offset into the .bss section, so we expect it to differ.

STB_LOCAL is documented on the ELF spec at http://www.sco.com/developers/gabi/2003-12-17/ch4.symtab.html:

STB_LOCAL Local symbols are not visible outside the object file containing their definition. Local symbols of the same name may exist in multiple files without interfering with each other

which makes it a perfect choice to represent static.

Functions without static are STB_GLOBAL, and the spec says:

When the link editor combines several relocatable object files, it does not allow multiple definitions of STB_GLOBAL symbols with the same name.

which is coherent with the link errors on multiple non static definitions.

If we crank up the optimization with -O3, the sf symbol is removed entirely from the symbol table: it cannot be used from outside anyways. TODO why keep static functions on the symbol table at all when there is no optimization? Can they be used for anything?

• Same for variables: https://stackoverflow.com/a/14339047/895245
• extern is the opposite of static, and functions are already extern by default: How do I use extern to share variables between source files?

C++ anonymous namespaces

In C++, you might want to use anonymous namespaces instead of static, which achieves a similar effect, but further hides type definitions: Unnamed/anonymous namespaces vs. static functions

I recently ran into the same thing, and suggest this function for MSTest:

public bool AssertThrows(Action action) where T : Exception
{
    try {action();
}
catch(Exception exception)
{
    if (exception.GetType() == typeof(T))
        return true;
}
    return false;
}

Usage:

Assert.IsTrue(AssertThrows<FormatException>(delegate{ newMyMethod(MyParameter); }));

There is more in Assert that a particular exception has occured (Assert.Throws in MSTest).

Here's a function that works for all 256 bytes, and ensures you'll see a character for each value:

static char asciiSymbol( byte val )
{
    if( val < 32 ) return '.';  // Non-printable ASCII
    if( val < 127 ) return (char)val;   // Normal ASCII
    // Workaround the hole in Latin-1 code page
    if( val == 127 ) return '.';
    if( val < 0x90 ) return "€.‚ƒ„…†‡ˆ‰Š‹Œ.Ž."[ val & 0xF ];
    if( val < 0xA0 ) return ".‘’“”•–—˜™š›œ.žŸ"[ val & 0xF ];
    if( val == 0xAD ) return '.';   // Soft hyphen: this symbol is zero-width even in monospace fonts
    return (char)val;   // Normal Latin-1
}

You can avoid the loop and cut etc by using:

awk -F ':' '{system("ping " $1);}' config.txt

However it would be better if you post a snippet of your config.txt

More or less this page has answers but all are not at one place. I was dealing with the same issue and spent quite a good time on it. Now i have a better understanding and i would like to share it here:

I Enabling Swagger ui with Spring websecurity:

If you have enabled Spring Websecurity by default it will block all the requests to your application and returns 401. However for the swagger ui to load in the browser swagger-ui.html makes several calls to collect data. The best way to debug is open swagger-ui.html in a browser(like google chrome) and use developer options('F12' key ). You can see several calls made when the page loads and if the swagger-ui is not loading completely probably some of them are failing.

you may need to tell Spring websecurity to ignore authentication for several swagger path patterns. I am using swagger-ui 2.9.2 and in my case below are the patterns that i had to ignore:

However if you are using a different version your's might change. you may have to figure out yours with developer option in your browser as i said before.

@Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/v2/api-docs", "/configuration/ui", 
            "/swagger-resources/**", "/configuration/**", "/swagger-ui.html"
            , "/webjars/**", "/csrf", "/");
}
}

II Enabling swagger ui with interceptor

Generally you may not want to intercept requests that are made by swagger-ui.html. To exclude several patterns of swagger below is the code:

Most of the cases pattern for web security and interceptor will be same.

@Configuration
@EnableWebMvc
public class RetrieveCiamInterceptorConfiguration implements WebMvcConfigurer {

@Autowired
RetrieveInterceptor validationInterceptor;

@Override
public void addInterceptors(InterceptorRegistry registry) {

    registry.addInterceptor(validationInterceptor).addPathPatterns("/**")
    .excludePathPatterns("/v2/api-docs", "/configuration/ui", 
            "/swagger-resources/**", "/configuration/**", "/swagger-ui.html"
            , "/webjars/**", "/csrf", "/");
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html")
      .addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**")
      .addResourceLocations("classpath:/META-INF/resources/webjars/");
}

}

Since you may have to enable @EnableWebMvc to add interceptors you may also have to add resource handlers to swagger similar to i have done in the above code snippet.

tried the above methods but mine stopped auto-compile when it felt like it, due to maximum files to watch have passed the limit.

run cat /proc/sys/fs/inotify/max_user_watches command .

if it's showing fewer files count including node_modules then open the file /etc/sysctl.conf in root privilege and append

fs.inotify.max_user_watches=524288 into the file and save

run again the cat command to see the result. It will work! hopefully!

pip search command does not show installed packages, but search packages in pypi.

Use pip freeze command and grep to see installed packages:

If you have downloaded several Jdks you have to delete all except of the JDK you want to use!

For ASP.NET Core you'll need to spell it out:

@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.Path}{Context.Request.QueryString}")

Or you can add a using statement to your view:

@using Microsoft.AspNetCore.Http.Extensions

then

@Context.Request.GetDisplayUrl()

The _ViewImports.cshtml might be a better place for that @using

The reason is your result assigned to the returning Task which represents continuation of your method, and you have a different Task in your method which is running, if you directly assign Task like this you will get your expected results:

var task = Task.Run(() =>
        {
            for (int i = 10; i < 432543543; i++)
            {
                // just for a long job
                double d3 = Math.Sqrt((Math.Pow(i, 5) - Math.Pow(i, 2)) / Math.Sin(i * 8));
            }
           return "Foo Completed.";

        });

        while (task.Status != TaskStatus.RanToCompletion)
        {
            Console.WriteLine("Thread ID: {0}, Status: {1}", Thread.CurrentThread.ManagedThreadId,task.Status);

        }

        Console.WriteLine("Result: {0}", task.Result);
        Console.WriteLine("Finished.");
        Console.ReadKey(true);

The output:

Consider this for better explanation: You have a Foo method,let's say it Task A, and you have a Task in it,let's say it Task B, Now the running task, is Task B, your Task A awaiting for Task B result.And you assing your result variable to your returning Task which is Task A, because Task B doesn't return a Task, it returns a string. Consider this:

If you define your result like this:

Task result = Foo(5);

You won't get any error.But if you define it like this:

string result = Foo(5);

You will get:

Cannot implicitly convert type 'System.Threading.Tasks.Task' to 'string'

But if you add an await keyword:

string result = await Foo(5);

Again you won't get any error.Because it will wait the result (string) and assign it to your result variable.So for the last thing consider this, if you add two task into your Foo Method:

private static async Task<string> Foo(int seconds)
{
    await Task.Run(() =>
        {
            for (int i = 0; i < seconds; i++)
            {
                Console.WriteLine("Thread ID: {0}, second {1}.", Thread.CurrentThread.ManagedThreadId, i);
                Task.Delay(TimeSpan.FromSeconds(1)).Wait();
            }

            // in here don't return anything
        });

   return await Task.Run(() =>
        {
            for (int i = 0; i < seconds; i++)
            {
                Console.WriteLine("Thread ID: {0}, second {1}.", Thread.CurrentThread.ManagedThreadId, i);
                Task.Delay(TimeSpan.FromSeconds(1)).Wait();
            }

            return "Foo Completed.";
        });
}

And if you run the application, you will get the same results.(WaitingForActivation) Because now, your Task A is waiting those two tasks.

If you want to call a function on clicking of submit button then you have
to use ajax or jquery,if you want to call your php function after submission of form you can do that as :

<html>
<body>
<form method="post" action="display()">
<input type="text" name="studentname">
<input type="submit" value="click">
</form>
<?php
function display()
{
echo "hello".$_POST["studentname"];
}
if($_SERVER['REQUEST_METHOD']=='POST')
{
       display();
} 
?>
</body>
</html>

Not really sure what you want your final layout to look like- but that fixes the colspan problem too.

Documentation says it's just a shortcut for creating readonly properties. So

@property
def x(self):
    return self._x

is equivalent to

def getx(self):
    return self._x
x = property(getx)

Welcome to the world of Data Oriented Design. The basic mantra is to Sort, Eliminate Branches, Batch, Eliminate virtual calls - all steps towards better locality.

Since you tagged the question with C++, here's the obligatory typical C++ Bullshit. Tony Albrecht's Pitfalls of Object Oriented Programming is also a great introduction into the subject.

FindBugs also puts a red-x against files/packages to indicate static code analysis errors.

Basically, "assert true" will pass and "assert false" will fail. Let's looks at how this will work:

public static void main(String[] args)
{
    String s1 = "Hello";
    assert checkInteger(s1);
}

private static boolean checkInteger(String s)
{
    try {
        Integer.parseInt(s);
        return true;
    }
    catch(Exception e)
    {
        return false;
    }
}

According to the error message, you declared myLoc as a pointer to an NSInteger (NSInteger *myLoc) rather than an actual NSInteger (NSInteger myLoc). It needs to be the latter.

  InputStream IS=new URL("http://www.petrol.si/api/gas_prices.json").openStream();   

  ByteArrayOutputStream BAOS=new ByteArrayOutputStream();
  IOUtils.copy(IS, BAOS);
  String d= new String(BAOS.toByteArray(),"UTF-8");           

System.out.println(d);

  AND YEAR(TIMESTAMP)=2011

SELECT * FROM my_table WHERE my_column = 'my string'
COLLATE Latin1_General_CS_AS

This would make a case sensitive search.

EDIT

As stated in kouton's comment here and tormuto's comment here whosoever faces problem with the below collation

COLLATE Latin1_General_CS_AS

should first check the default collation for their SQL server, their respective database and the column in question; and pass in the default collation with the query expression. List of collations can be found here.

For anyone who stumbles upon this years later (like I did), I tweaked 6502's methods a little bit to allow the progress bar to decrease as well as increase. Useful in slightly more cases. Thanks 6502 for a great tool!

Basically, the only difference is that the whole line of #s and -s is written each time progress(x) is called, and the cursor is always returned to the start of the bar.

def startprogress(title):
    """Creates a progress bar 40 chars long on the console
    and moves cursor back to beginning with BS character"""
    global progress_x
    sys.stdout.write(title + ": [" + "-" * 40 + "]" + chr(8) * 41)
    sys.stdout.flush()
    progress_x = 0


def progress(x):
    """Sets progress bar to a certain percentage x.
    Progress is given as whole percentage, i.e. 50% done
    is given by x = 50"""
    global progress_x
    x = int(x * 40 // 100)                      
    sys.stdout.write("#" * x + "-" * (40 - x) + "]" + chr(8) * 41)
    sys.stdout.flush()
    progress_x = x


def endprogress():
    """End of progress bar;
    Write full bar, then move to next line"""
    sys.stdout.write("#" * 40 + "]\n")
    sys.stdout.flush()

Consider the case statement as well which is compatible with most sh-based shells:

case $str in
/*)
    echo 1
    ;;
*)
    echo 0
    ;;
esac

Use to_string().
example :

#include <iostream>   
#include <string>  

using namespace std;
int main ()
{
    string pi = "pi is " + to_string(3.1415926);
    cout<< "pi = "<< pi << endl;

  return 0;
}

run it yourself : http://ideone.com/7ejfaU
These are available as well :

string to_string (int val);
string to_string (long val);
string to_string (long long val);
string to_string (unsigned val);
string to_string (unsigned long val);
string to_string (unsigned long long val);
string to_string (float val);
string to_string (double val);
string to_string (long double val);

I think that the two terms you're looking for are equality (==) and identity (is). For example:

>>> a = [1,2,3]
>>> b = [1,2,3]
>>> a == b
True       <-- a and b have values which are equal
>>> a is b
False      <-- a and b are not the same list object

Due to the way Python works, it is necessary for it to run your modules when it imports them.

To prevent code in the module from being executed when imported, but only when run directly, you can guard it with this if:

if __name__ == "__main__":
    # this won't be run when imported

You may want to put this code in a main() method, so that you can either execute the file directly, or import the module and call the main(). For example, assume this is in the file foo.py.

def main():
    print "Hello World"

if __name__ == "__main__":
    main()

This program can be run either by going python foo.py, or from another Python script:

import foo

...

foo.main()

The below should work

describe "#foo"
  it "should call 'bar' with appropriate arguments" do
     subject.stub(:bar)
     subject.foo
     expect(subject).to have_received(:bar).with("Invalid number of arguments")
  end
end

Although System.Collections.Generic.Dictionary matches the tag "hashmap" and will work well in your example, it is not an exact equivalent of C++'s std::map - std::map is an ordered collection.

If ordering is important you should use SortedDictionary.

This worked for me:

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(10, TimeUnit.SECONDS)
    .readTimeout(10, TimeUnit.SECONDS)
    .writeTimeout(10, TimeUnit.SECONDS)
    .retryOnConnectionFailure(false) <-- not necessary but useful!
    .build();

Use

SELECT 1 FROM table LIMIT 1;

to prevent all records from being read.

change your code to this

$start_date = new DateTime( "@" . $dbResult->db_timestamp );

and it will work fine

Just remove the comma like this:

<article class="column wrapper"> 

According to this: http://www.vistax64.com/vista-installation-setup/33219-regsvr32-error-0x80004005.html

Run it in a elevated command prompt.

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

execFile('helloworld.py') does the job for me. A thing to note is to enter the complete directory name of the .py file if it isnt in the Python folder itself (atleast this is the case on Windows)

For example, execFile('C:/helloworld.py')

So the problem must be with your JCE Unlimited Strength installation.

Be sure you overwrite the local_policy.jar and US_export_policy.jar in both your JDK's jdk1.6.0_25\jre\lib\security\ and in your JRE's lib\security\ folder.

In my case I would place the new .jars in:

C:\Program Files\Java\jdk1.6.0_25\jre\lib\security

and

C:\Program Files\Java\jre6\lib\security

If you are running Java 8 and you encounter this issue. Below steps should help!

Go to your JRE installation (e.g - jre1.8.0_181\lib\security\policy\unlimited) copy local_policy.jar and replace it with 'local_policy.jar' in your JDK installation directory (e.g - jdk1.8.0_141\jre\lib\security).

you can also use textbox events -

<input id="txt1" type="text" onchange="SetDefault($(this).val());" onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();">

function SetDefault(Text){
  alert(Text);
}

Try This

As benjymous pointed out, you can use Newtonsoft.Json with a temporary object and deserialize/serialize.

var obj = JsonConvert.DeserializeObject(jsonString); 
var formatted = JsonConvert.SerializeObject(obj, Formatting.Indented);

Autoplay works only with /v/ instead of /embed/, so change the src to:

src="//www.youtube.com/v/qUJYqhKZrwA?autoplay=1&showinfo=0&controls=0"

You can transpose the array if you want to get the length of the other dimension.

len(np.array([[2,3,1,0], [2,3,1,0], [3,2,1,1]]).T)

Use a Temp Table or a Table variable, e.g.

select 'A' as [value]
into #tmp
union
select 'B'
union 
select 'C'

and then

SELECT   
blah 
FROM    foo 
WHERE   myField IN (select [value] from #tmp) 

or

SELECT   
f.blah 
FROM foo f INNER JOIN #tmp t ON f.myField = t.[value]

I've got correct solution here.

The best way to correctly install gcc-4.9 and set it as your default gcc version use:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9

The --slave, with g++, will cause g++ to be switched along with gcc, to the same version. But, at this point gcc-4.9 will be your only version configured in update-alternatives, so add 4.8 to update-alternatives, so there actually is an alternative, by using:

sudo apt-get install gcc-4.8 g++-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8

Then you can check which one that is set, and change back and forth using:

sudo update-alternatives --config gcc

NOTE: You could skip installing the PPA Repository and just use /usr/bin/gcc-4.9-base but I prefer using the fresh updated toolchains.

you can create a List[] and initialize them by for loop. it compiles without errors:

List<e>[] l;
for(int i = 0; i < l.length; i++){
    l[i] = new ArrayList<e>();
}

it works with arrayList[] l as well.

You can try this lib, easy to change color for the switch button.
https://github.com/kyleduo/SwitchButton

I think you want the selected item of the spinner when button is clicked..

Try getSelectedItem():

spinner.getSelectedItem()

Invoking any method on any null reference will always result in an exception. Test if the object is null first:

List<Object> test = null;
if (test != null && !test.isEmpty()) {
    // ...
}

Alternatively, write a method to encapsulate this logic:

public static <T> boolean IsNullOrEmpty(Collection<T> list) {
    return list == null || list.isEmpty();
}

Then you can do:

List<Object> test = null;
if (!IsNullOrEmpty(test)) {
    // ...
}

Here is an example of the working code.

template<typename T>
using toStringFn = decltype(std::declval<const T>().toString());

template <class T, toStringFn<T>* = nullptr>
std::string optionalToString(const T* obj, int)
{
    return obj->toString();
}

template <class T>
std::string optionalToString(const T* obj, long)
{
    return "toString not defined";
}

int main()
{
    A* a;
    B* b;

    std::cout << optionalToString(a, 0) << std::endl; // This is A
    std::cout << optionalToString(b, 0) << std::endl; // toString not defined
}

toStringFn<T>* = nullptr will enable the function which takes extra int argument which has a priority over function which takes long when called with 0.

You can use the same principle for the functions which returns true if function is implemented.

template <typename T>
constexpr bool toStringExists(long)
{
    return false;
}

template <typename T, toStringFn<T>* = nullptr>
constexpr bool toStringExists(int)
{
    return true;
}


int main()
{
    A* a;
    B* b;

    std::cout << toStringExists<A>(0) << std::endl; // true
    std::cout << toStringExists<B>(0) << std::endl; // false
}

Yes, it is recommended to put the GA code in the footer anyway, as the page shouldnt count as a page visit until its read all the markup.

You can use this query to show the size of a table (although you need to substitute the variables first):

SELECT 
    table_name AS `Table`, 
    round(((data_length + index_length) / 1024 / 1024), 2) `Size in MB` 
FROM information_schema.TABLES 
WHERE table_schema = "$DB_NAME"
    AND table_name = "$TABLE_NAME";

or this query to list the size of every table in every database, largest first:

SELECT 
     table_schema as `Database`, 
     table_name AS `Table`, 
     round(((data_length + index_length) / 1024 / 1024), 2) `Size in MB` 
FROM information_schema.TABLES 
ORDER BY (data_length + index_length) DESC;

Close and re-open the tab. That should do the trick.

Error jet 4 oledb It Can be possible upgrade kb4041678 kb4041681

For me, the problem was that catalina.sh didnt have execute permissions. The "Unable to open debugger port in intellij" message appeared in Intellij, but it sort of masked the 'could not execute catalina.sh' error that appeared in the logs immediately prior.

By default is private. Unless they're nested, classes are internal.

The chosen solution does not preserve the round corner style. To preserve the round corners, you should reduce the width and height a little bit and remove the border radius 0. Also it doesn't show the vertical scroll bar...

.modal-dialog {
  width: 98%;
  height: 92%;
  padding: 0;
}

.modal-content {
  height: 99%;
}

Another Note: z-index must be considered when looking at children objects relative to other objects.

For example

<div class="container">
    <div class="branch_1">
        <div class="branch_1__child"></div>
    </div>
    <div class="branch_2">
        <div class="branch_2__child"></div>
    </div>
</div>

If you gave branch_1__child a z-index of 99 and you gave branch_2__child a z-index of 1, but you also gave your branch_2 a z-index of 10 and your branch_1 a z-index of 1, your branch_1__child still will not show up in front of your branch_2__child

Anyways, what I'm trying to say is; if a parent of an element you'd like to be placed in front has a lower z-index than its relative, that element will not be placed higher.

The z-index is relative to its containers. A z-index placed on a container farther up in the hierarchy basically starts a new "layer"

Here's a fiddle to play around:

https://jsfiddle.net/orkLx6o8/

You will need to do a couple of things to get this going, since your parameter is getting multiple values you need to create a Table Type and make your store procedure accept a parameter of that type.

Split Function Works Great when you are getting One String containing multiple values but when you are passing Multiple values you need to do something like this....

TABLE TYPE

CREATE TYPE dbo.TYPENAME AS TABLE   (     arg int    )  GO 

Stored Procedure to Accept That Type Param

 CREATE PROCEDURE mainValues   @TableParam TYPENAME READONLY  AS     BEGIN     SET NOCOUNT ON;   --Temp table to store split values   declare @tmp_values table (   value nvarchar(255) not null);        --function splitting values     INSERT INTO @tmp_values (value)    SELECT arg FROM @TableParam      SELECT * FROM @tmp_values  --<-- For testing purpose END 

EXECUTE PROC

Declare a variable of that type and populate it with your values.

 DECLARE @Table TYPENAME     --<-- Variable of this TYPE   INSERT INTO @Table                --<-- Populating the variable   VALUES (331),(222),(876),(932)  EXECUTE mainValues @Table   --<-- Stored Procedure Executed  

Result

╔═══════╗ ║ value ║ ╠═══════╣ ║   331 ║ ║   222 ║ ║   876 ║ ║   932 ║ ╚═══════╝ 

Eclipse has no impact on Mac OS beyond it directory, so there is no problem uninstalling.

I think that What you are facing is the result of Eclipse switching the plugin distribution system recently. There are now two redundant and not very compatible means of installing plugins. It's a complete mess. You may be better off (if possible) installing a more recent version of Eclipse (maybe even the 3.5 milestones) as they seem to be more stable in that regard.

All answers above - do not work. So I will put here a function that works on 4 and 9 android

private String getCurrentLanguage(){
   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
      return LocaleList.getDefault().get(0).getLanguage();
   } else{
      return Locale.getDefault().getLanguage();
   }
}

I had the same problem and was able to run a schema-less query using an existing Mongoose connection with the code below. I've added a simple constraint 'a=b' to show where you would add such a constraint:

var action = function (err, collection) {
    // Locate all the entries using find
    collection.find({'a':'b'}).toArray(function(err, results) {
        /* whatever you want to do with the results in node such as the following
             res.render('home', {
                 'title': 'MyTitle',
                 'data': results
             });
        */
    });
};

mongoose.connection.db.collection('question', action);

If you want a simple one liner that will do it all for you (assuming by no value you mean a blank cell):

=(ROWS(A:A) + ROWS(B:B) + ROWS(C:C)) - COUNTIF(A:C, "")

If by no value you mean the cell contains a 0

=(ROWS(A:A) + ROWS(B:B) + ROWS(C:C)) - COUNTIF(A:C, 0)

The formula works by first summing up all the rows that are in columns A, B, and C (if you need to count more rows, just increase the columns in the range. E.g. ROWS(A:A) + ROWS(B:B) + ROWS(C:C) + ROWS(D:D) + ... + ROWS(Z:Z)).

Then the formula counts the number of values in the same range that are blank (or 0 in the second example).

Last, the formula subtracts the total number of cells with no value from the total number of rows. This leaves you with the number of cells in each row that contain a value

Try using viewport (vh, vm) units of measure at the body level

html, body { margin: 0; padding: 0; } body { min-height: 100vh; }

Use vh units for horizontal margins, paddings, and borders on the body and subtract them from the min-height value.

I've had bizarre results using vh,vm units on elements within the body, especially when re-sizing.

This will help anyone who wants to configure hikaricp for their application with spring auto configuration. For my project, im using spring boot 2 with hikaricp as the JDBC connection pool and mysql as the database. One thing I didn't see in other answers was the data-source-properties which can be used to set various properties that are not available at the spring.datasource.hikari.* path. This is equivalent to using the HikariConfig class. To configure the datasource and hikaricp connection pool for mysql specific properties I used the spring auto configure annotation and the following properties in the application.yml file.

Place @EnableAutoConfiguration on one of your configuration bean files.

application.yml file can look like this.

spring:
  datasource:
    url: 'jdbc:mysql://127.0.0.1:3306/DATABASE?autoReconnect=true&useSSL=false'
    username: user_name
    password: password
    hikari:

There are several ways to try to prevent line breaks, and the phrase “a newer construct” might refer to more than one way—that’s actually the most reasonable interpretation. They probably mostly think of the CSS declaration white-space:nowrap and possibly the no-break space character. The different ways are not equivalent, far from that, both in theory and especially in practice, though in some given case, different ways might produce the same result.

There is probably nothing real to be gained by switching from the HTML attribute to the somewhat clumsier CSS way, and you would surely lose when style sheets are disabled. But even the nowrap attribute does no work in all situations. In general, what works most widely is the nobr markup, which has never made its way to any specifications but is alive and kicking: <td><nobr>...</nobr></td>.

You can specify gradients for colours in certain circumstances in CSS3, and of course borders can be set to a colour, so you should be able to use a gradient as a border colour. This would include the option of specifying a transparent colour, which means you should be able to achieve the effect you're after.

However, I've never seen it used, and I don't know how well supported it is by current browsers. You'll certainly need to accept that at least some of your users won't be able to see it.

A quick google turned up these two pages which should help you on your way:

• CSS3 Gradient Borders
• http://designshack.co.uk/tutorials/introduction-to-css3-part-2-borders

Hope that helps.

It's a quite old question, but as it's got many views I think it's worth to present an alternative, and in my opinion very elegant, solution.

In order to read a tree structure you can use recursive Common Table Expressions (CTEs). It gives a possibility to fetch whole tree structure at once, have the information about the level of the node, its parent node and order within children of the parent node.

Let me show you how this would work in PostgreSQL 9.1.

1. Create a structure

   CREATE TABLE tree (
       id int  NOT NULL,
       name varchar(32)  NOT NULL,
       parent_id int  NULL,
       node_order int  NOT NULL,
       CONSTRAINT tree_pk PRIMARY KEY (id),
       CONSTRAINT tree_tree_fk FOREIGN KEY (parent_id) 
         REFERENCES tree (id) NOT DEFERRABLE
   );
   
   
   insert into tree values
     (0, 'ROOT', NULL, 0),
     (1, 'Node 1', 0, 10),
     (2, 'Node 1.1', 1, 10),
     (3, 'Node 2', 0, 20),
     (4, 'Node 1.1.1', 2, 10),
     (5, 'Node 2.1', 3, 10),
     (6, 'Node 1.2', 1, 20);
   

2. Write a query

   WITH RECURSIVE 
   tree_search (id, name, level, parent_id, node_order) AS (
     SELECT 
       id, 
       name,
       0,
       parent_id, 
       1 
     FROM tree
     WHERE parent_id is NULL
   
     UNION ALL 
     SELECT 
       t.id, 
       t.name,
       ts.level + 1, 
       ts.id, 
       t.node_order 
     FROM tree t, tree_search ts 
     WHERE t.parent_id = ts.id 
   ) 
   SELECT * FROM tree_search 
   WHERE level > 0 
   ORDER BY level, parent_id, node_order;
   

   Here are the results:

    id |    name    | level | parent_id | node_order 
   ----+------------+-------+-----------+------------
     1 | Node 1     |     1 |         0 |         10

   The tree nodes are ordered by a level of depth. In the final output we would present them in the subsequent lines.

   For each level, they are ordered by parent_id and node_order within the parent. This tells us how to present them in the output - link node to the parent in this order.

   Having such a structure it wouldn't be difficult to make a really nice presentation in HTML.

   Recursive CTEs are available in PostgreSQL, IBM DB2, MS SQL Server and Oracle.

   If you'd like to read more on recursive SQL queries, you can either check the documentation of your favourite DBMS or read my two articles covering this topic:

   • Do It In SQL: Recursive Tree Traversal
   • Get to know the power of SQL recursive queries

Use on :

$('#registered_participants').on('click', '.new_participant_form', function() {

So that the click is delegated to any element in #registered_participants having the class new_participant_form, even if it's added after you bound the event handler.

You can also do as follow :

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main2)
        setSupportActionBar(toolbar)
        setTitle("Activity 2")
    }

One liner for Classification:

Classifying data into pre-defined categories

One liner for Clustering:

Grouping data into a set of categories

Key difference:

Classification is taking data and putting it into pre-defined categories and in Clustering the set of categories, that you want to group the data into, is not known beforehand.

Conclusion:

• Classification assigns the category to 1 new item, based on already labeled items while Clustering takes a bunch of unlabeled items and divide them into the categories
• In Classification, the categories\groups to be divided are known beforehand while in Clustering, the categories\groups to be divided are unknown beforehand
• In Classification, there are 2 phases – Training phase and then the test phase while in Clustering, there is only 1 phase – dividing of training data in clusters
• Classification is Supervised Learning while Clustering is Unsupervised Learning

I have written a long post on the same topic which you can find here:

The answer posted by @schellack is perfect for most scenarios, but I wanted Beyond Compare to simulate the '2 Way merge with a result panel' view that Visual Studio uses in its own merge window.

This config hides the middle panel (which is unused in most cases AFAIK).

 %1 %2 "" %4 /title1=%6 /title2=%7 /title3="" /title4=%9

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

You don't have an Internet connection to rubygems.org.

This happens sometimes if the site is down or blocked.

This command can show you if your connection has a way to reach rubygems.org:

traceroute rubygems.org

This is an old thread, but I thought I would post this link, as it helped me quite a bit on this issue. Essentially what it's saying is the server configuration can override the php config. From the article:

For example mod_fastcgi has an option called "-idle-timeout" which controls the idle time of the script. So if the script does not output anything to the fastcgi handler for that many seconds then fastcgi would terminate it. The setup is somewhat like this:

Apache <-> mod_fastcgi <-> php processes

The article has other examples and further explanation. Hope this helps somebody else.

TL;DR

TEXT

• fixed max size of 65535 characters (you cannot limit the max size)
• takes 2 + c bytes of disk space, where c is the length of the stored string.
• cannot be (fully) part of an index. One would need to specify a prefix length.

VARCHAR(M)

• variable max size of M characters
• M needs to be between 1 and 65535
• takes 1 + c bytes (for M ≤ 255) or 2 + c (for 256 ≤ M ≤ 65535) bytes of disk space where c is the length of the stored string
• can be part of an index

More Details

TEXT has a fixed max size of 2¹6-1 = 65535 characters.
VARCHAR has a variable max size M up to M = 2¹6-1.
So you cannot choose the size of TEXT but you can for a VARCHAR.

The other difference is, that you cannot put an index (except for a fulltext index) on a TEXT column.
So if you want to have an index on the column, you have to use VARCHAR. But notice that the length of an index is also limited, so if your VARCHAR column is too long you have to use only the first few characters of the VARCHAR column in your index (See the documentation for CREATE INDEX).

But you also want to use VARCHAR, if you know that the maximum length of the possible input string is only M, e.g. a phone number or a name or something like this. Then you can use VARCHAR(30) instead of TINYTEXT or TEXT and if someone tries to save the text of all three "Lord of the Ring" books in your phone number column you only store the first 30 characters :)

Edit: If the text you want to store in the database is longer than 65535 characters, you have to choose MEDIUMTEXT or LONGTEXT, but be careful: MEDIUMTEXT stores strings up to 16 MB, LONGTEXT up to 4 GB. If you use LONGTEXT and get the data via PHP (at least if you use mysqli without store_result), you maybe get a memory allocation error, because PHP tries to allocate 4 GB of memory to be sure the whole string can be buffered. This maybe also happens in other languages than PHP.

However, you should always check the input (Is it too long? Does it contain strange code?) before storing it in the database.

Notice: For both types, the required disk space depends only on the length of the stored string and not on the maximum length.
E.g. if you use the charset latin1 and store the text "Test" in VARCHAR(30), VARCHAR(100) and TINYTEXT, it always requires 5 bytes (1 byte to store the length of the string and 1 byte for each character). If you store the same text in a VARCHAR(2000) or a TEXT column, it would also require the same space, but, in this case, it would be 6 bytes (2 bytes to store the string length and 1 byte for each character).

For more information have a look at the documentation.

Finally, I want to add a notice, that both, TEXT and VARCHAR are variable length data types, and so they most likely minimize the space you need to store the data. But this comes with a trade-off for performance. If you need better performance, you have to use a fixed length type like CHAR. You can read more about this here.

Here's an example of a Comparator that will work for any zero arg method that returns a Comparable. Does something like this exist in a jdk or library?

import java.lang.reflect.Method;
import java.util.Comparator;

public class NamedMethodComparator implements Comparator<Object> {

    //
    // instance variables
    //

    private String methodName;

    private boolean isAsc;

    //
    // constructor
    //

    public NamedMethodComparator(String methodName, boolean isAsc) {
        this.methodName = methodName;
        this.isAsc = isAsc;
    }

    /**
     * Method to compare two objects using the method named in the constructor.
     */
    @Override
    public int compare(Object obj1, Object obj2) {
        Comparable comp1 = getValue(obj1, methodName);
        Comparable comp2 = getValue(obj2, methodName);
        if (isAsc) {
            return comp1.compareTo(comp2);
        } else {
            return comp2.compareTo(comp1);
        }
    }

    //
    // implementation
    //

    private Comparable getValue(Object obj, String methodName) {
        Method method = getMethod(obj, methodName);
        Comparable comp = getValue(obj, method);
        return comp;
    }

    private Method getMethod(Object obj, String methodName) {
        try {
            Class[] signature = {};
            Method method = obj.getClass().getMethod(methodName, signature);
            return method;
        } catch (Exception exp) {
            throw new RuntimeException(exp);
        }
    }

    private Comparable getValue(Object obj, Method method) {
        Object[] args = {};
        try {
            Object rtn = method.invoke(obj, args);
            Comparable comp = (Comparable) rtn;
            return comp;
        } catch (Exception exp) {
            throw new RuntimeException(exp);
        }
    }

}

There is a python package exactly for this purpose. see cstruct2py

cstruct2py is a pure python library for generate python classes from C code and use them to pack and unpack data. The library can parse C headres (structs, unions, enums, and arrays declarations) and emulate them in python. The generated pythonic classes can parse and pack the data.

For example:

typedef struct {
  int x;
  int y;
} Point;

after generating pythonic class...
p = Point(x=0x1234, y=0x5678)
p.packed == "\x34\x12\x00\x00\x78\x56\x00\x00"

How to use

First we need to generate the pythonic structs:

import cstruct2py
parser = cstruct2py.c2py.Parser()
parser.parse_file('examples/example.h')

Now we can import all names from the C code:

parser.update_globals(globals())

We can also do that directly:

A = parser.parse_string('struct A { int x; int y;};')

Using types and defines from the C code

a = A()
a.x = 45
print a
buf = a.packed
b = A(buf)
print b
c = A('aaaa11112222', 2)
print c
print repr(c)

The output will be:

{'x':0x2d, 'y':0x0}
{'x':0x2d, 'y':0x0}
{'x':0x31316161, 'y':0x32323131}
A('aa111122', x=0x31316161, y=0x32323131)

Clone

For clone cstruct2py run:

git clone https://github.com/st0ky/cstruct2py.git --recursive

These answers were helpful, but I wanted to share my answer with both the app.config part and the c# code part, so there is less guessing for the next person.

<log4net>
  <appender name="SomeName" type="log4net.Appender.RollingFileAppender">
    <file value="c:/Console.txt" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <datePattern value="yyyyMMdd" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="1MB" />
  </appender>
  <appender name="Summary" type="log4net.Appender.FileAppender">
    <file value="SummaryFile.log" />
    <appendToFile value="true" />
  </appender>
  <root>
    <level value="ALL" />
    <appender-ref ref="SomeName" />
  </root>
  <logger additivity="false" name="Summary">
    <level value="DEBUG"/>
    <appender-ref ref="Summary" />
  </logger>
</log4net>

Then in code:

ILog Log = LogManager.GetLogger("SomeName");
ILog SummaryLog = LogManager.GetLogger("Summary");
Log.DebugFormat("Processing");
SummaryLog.DebugFormat("Processing2"));

Here c:/Console.txt will contain "Processing" ... and \SummaryFile.log will contain "Processing2"

Combining above answer with ability to click again and again without clicking outside iframe.

    var eventListener = window.addEventListener('blur', function() {
    if (document.activeElement === document.getElementById('contentIFrame')) {
        toFunction(); //function you want to call on click
        setTimeout(function(){ window.focus(); }, 0);
    }
    window.removeEventListener('blur', eventListener );
    });

For a bit more flexibility than with micronyks answer, you can do it like that:

1. In your template, add #myIdentifier to the element you want to obtain the width from. Example:

<p #myIdentifier>
  my-component works!
</p>

2. In your controller, you can use this with @ViewChild('myIdentifier') to get the width:

import {AfterViewInit, Component, ElementRef, OnInit, ViewChild} from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss']
})
export class MyComponentComponent implements AfterViewInit {

  constructor() { }

  ngAfterViewInit() {
    console.log(this.myIdentifier.nativeElement.offsetWidth);
  }

  @ViewChild('myIdentifier')
  myIdentifier: ElementRef;

}

Security

About the security risk with ElementRef, like this, there is none. There would be a risk, if you would modify the DOM using an ElementRef. But here you are only getting DOM Elements so there is no risk. A risky example of using ElementRef would be: this.myIdentifier.nativeElement.onclick = someFunctionDefinedBySomeUser;. Like this Angular doesn't get a chance to use its sanitisation mechanisms since someFunctionDefinedBySomeUser is inserted directly into the DOM, skipping the Angular sanitisation.

<div style="width:300px; text-align:right;">
        <img src="someimgage.gif">
</div>

An important addition to Travis' answer; you need to put the getWidth() up in your document body to make sure that the scrollbar width is counted, else scrollbar width of the browser subtracted from getWidth(). What i did ;

<body>
<script>
function getWidth(){
return Math.max(document.body.scrollWidth,
document.documentElement.scrollWidth,
document.body.offsetWidth,
document.documentElement.offsetWidth,
document.documentElement.clientWidth);
}
var aWidth=getWidth();
</script>
</body>

and call aWidth variable anywhere afterwards.

I had an issue in Pixel 3, Android 11 that when my service was running very short, then the foreground notification was not dismissed.

Adding 100ms delay before stopForeground() stopSelf() seems to help.

People write here that stopForeground() should be called before stopSelf(). I cannot confirm, but I guess it doesn't bother to do that.

public class AService extends Service {

@Override
public void onCreate() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        startForeground(
            getForegroundNotificationId(),
            channelManager.buildBackgroundInfoNotification(getNotificationTitle(), getNotificationText()),
            ServiceInfo.FOREGROUND_SERVICE_TYPE_DATA_SYNC);
    } else {
        startForeground(getForegroundNotificationId(),
            channelManager.buildBackgroundInfoNotification(getNotificationTitle(), getNotificationText())
        );
    }

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    startForeground();

    if (hasQueueMoreItems()) {
        startWorkerThreads();
    } else {
        stopForeground(true);
        stopSelf();
    }
    return START_STICKY;
}

private class WorkerRunnable implements Runnable {

    @Override
    public void run() {

        while (getItem() != null && !isLoopInterrupted) {
            doSomething(getItem())   
        }

        waitALittle();
        stopForeground(true);
        stopSelf();
    }

    private void waitALittle() {
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
}

Here is an example that works for files which cannot be read in with the read.table function. This example reads a .xls file.

url <-"https://www1.toronto.ca/City_Of_Toronto/Information_Technology/Open_Data/Data_Sets/Assets/Files/fire_stns.zip"

temp <- tempfile()
temp2 <- tempfile()

download.file(url, temp)
unzip(zipfile = temp, exdir = temp2)
data <- read_xls(file.path(temp2, "fire station x_y.xls"))

unlink(c(temp, temp2))
