Create a "module" object and declare variables in there. Unlike class-objects that have to be instantiated each time, the module objects are always available. Therefore, a public variable, function, or property in a "module" will be available to all the other objects in the VBA project, macro, Excel formula, or even within a MS Access JET-SQL query def.

This error is quite right and highlights a contextual syntax issue. Can be reproduced by performing any kind "non-assignable" syntax. For instance:

function Syntax($hello) { .... then attempt to call the function as though a property and assign a value.... $this->Syntax('Hello') = 'World';

The above error will be thrown because syntactially the statement is wrong. The right assignment of 'World' cannot be written in the context you have used (i.e. syntactically incorrect for this context). 'Cannot use function return value' or it could read 'Cannot assign the right-hand value to the function because its read-only'

The specific error in the OPs code is as highlighted, using brackets instead of square brackets.

NEVER grow a DataFrame!

TLDR; (just read the bold text)

Most answers here will tell you how to create an empty DataFrame and fill it out, but no one will tell you that it is a bad thing to do.

Here is my advice: Accumulate data in a list, not a DataFrame.

Use a list to collect your data, then initialise a DataFrame when you are ready. Either a list-of-lists or list-of-dicts format will work, pd.DataFrame accepts both.

data = []
for a, b, c in some_function_that_yields_data():
    data.append([a, b, c])

df = pd.DataFrame(data, columns=['A', 'B', 'C'])

Pros of this approach:

1. It is always cheaper to append to a list and create a DataFrame in one go than it is to create an empty DataFrame (or one of NaNs) and append to it over and over again.

2. Lists also take up less memory and are a much lighter data structure to work with, append, and remove (if needed).

3. dtypes are automatically inferred (rather than assigning object to all of them).

4. A RangeIndex is automatically created for your data, instead of you having to take care to assign the correct index to the row you are appending at each iteration.

If you aren't convinced yet, this is also mentioned in the documentation:

Iteratively appending rows to a DataFrame can be more computationally intensive than a single concatenate. A better solution is to append those rows to a list and then concatenate the list with the original DataFrame all at once.

But what if my function returns smaller DataFrames that I need to combine into one large DataFrame?

That's fine, you can still do this in linear time by growing or creating a python list of smaller DataFrames, then calling pd.concat.

small_dfs = []
for small_df in some_function_that_yields_dataframes():
    small_dfs.append(small_df)

large_df = pd.concat(small_dfs, ignore_index=True)

or, more concisely:

large_df = pd.concat(
    list(some_function_that_yields_dataframes()), ignore_index=True)

These options are horrible

append or concat inside a loop

Here is the biggest mistake I've seen from beginners:

df = pd.DataFrame(columns=['A', 'B', 'C'])
for a, b, c in some_function_that_yields_data():
    df = df.append({'A': i, 'B': b, 'C': c}, ignore_index=True) # yuck
    # or similarly,
    # df = pd.concat([df, pd.Series({'A': i, 'B': b, 'C': c})], ignore_index=True)

Memory is re-allocated for every append or concat operation you have. Couple this with a loop and you have a quadratic complexity operation.

The other mistake associated with df.append is that users tend to forget append is not an in-place function, so the result must be assigned back. You also have to worry about the dtypes:

df = pd.DataFrame(columns=['A', 'B', 'C'])
df = df.append({'A': 1, 'B': 12.3, 'C': 'xyz'}, ignore_index=True)

df.dtypes
A     object   # yuck!
B    float64
C     object
dtype: object

Dealing with object columns is never a good thing, because pandas cannot vectorize operations on those columns. You will need to do this to fix it:

df.infer_objects().dtypes
A      int64
B    float64
C     object
dtype: object

loc inside a loop

I have also seen loc used to append to a DataFrame that was created empty:

df = pd.DataFrame(columns=['A', 'B', 'C'])
for a, b, c in some_function_that_yields_data():
    df.loc[len(df)] = [a, b, c]

As before, you have not pre-allocated the amount of memory you need each time, so the memory is re-grown each time you create a new row. It's just as bad as append, and even more ugly.

Empty DataFrame of NaNs

And then, there's creating a DataFrame of NaNs, and all the caveats associated therewith.

df = pd.DataFrame(columns=['A', 'B', 'C'], index=range(5))
df
     A    B    C
0  NaN  NaN  NaN
1  NaN  NaN  NaN
2  NaN  NaN  NaN
3  NaN  NaN  NaN
4  NaN  NaN  NaN

It creates a DataFrame of object columns, like the others.

df.dtypes
A    object  # you DON'T want this
B    object
C    object
dtype: object

Appending still has all the issues as the methods above.

for i, (a, b, c) in enumerate(some_function_that_yields_data()):
    df.iloc[i] = [a, b, c]

The Proof is in the Pudding

Timing these methods is the fastest way to see just how much they differ in terms of their memory and utility.

If you are looking for Angular (v2+, currently version 8), try this answer or the official guide.

ORIGINAL ANSWER

I have rewritten your JS fiddle here: http://jsfiddle.net/YGQT9/

<div ng-app="myApp">

    <form name="saveTemplateData" action="#" ng-controller="FormCtrl" ng-submit="submitForm()">

        First name:    <br/><input type="text" name="form.firstname">    
        <br/><br/>

        Email Address: <br/><input type="text" ng-model="form.emailaddress"> 
        <br/><br/>

        <textarea rows="3" cols="25">
          Describe your reason for submitting this form ... 
        </textarea> 
        <br/>

        <input type="radio" ng-model="form.gender" value="female" />Female
        <input type="radio" ng-model="form.gender" value="male" />Male 
        <br/><br/>

        <input type="checkbox" ng-model="form.member" value="true"/> Already a member
        <input type="checkbox" ng-model="form.member" value="false"/> Not a member
        <br/>

        <input type="file" ng-model="form.file_profile" id="file_profile">
        <br/>

        <input type="file" ng-model="form.file_avatar" id="file_avatar">
        <br/><br/>

        <input type="submit">
    </form>
</div>

Here I'm using lots of angular directives(ng-controller, ng-model, ng-submit) where you were using basic html form submission. Normally all alternatives to "The angular way" work, but form submission is intercepted and cancelled by Angular to allow you to manipulate the data before submission

BUT the JSFiddle won't work properly as it doesn't allow any type of ajax/http post/get so you will have to run it locally.

For general advice on angular form submission see the cookbook examples

UPDATE The cookbook is gone. Instead have a look at the 1.x guide for for form submission

The cookbook for angular has lots of sample code which will help as the docs aren't very user friendly.

Angularjs changes your entire web development process, don't try doing things the way you are used to with JQuery or regular html/js, but for everything you do take a look around for some sample code, as there is almost always an angular alternative.

I got stuck on this issue for a long time following all the different remedies without avail.

I noticed that when adding a forward slash [/] to the end of the URL containing the dots [.], it did not throw a 404 error and it actually worked.

I finally solved the issue using a URL rewriter like IIS URL Rewrite to watch for a particular pattern and append the training slash.

My URL looks like this: /Contact/~firstname.lastname so my pattern is simply: /Contact/~(.*[^/])$

I got this idea from Scott Forsyth, see link below: http://weblogs.asp.net/owscott/handing-mvc-paths-with-dots-in-the-path

The most intuitive method is introduced in Java 11 Files.readString

import java.io.*;
import java.nio.file.Files;
import java.nio.file.Paths;

public class App {
    public static void main(String args[]) throws IOException {
        String content = Files.readString(Paths.get("D:\\sandbox\\mvn\\my-app\\my-app.iml"));
        System.out.print(content);
    }
}

PHP has this luxury from decades ago! ?

assert will terminate the program (usually with a message quoting the assert statement) if its argument turns out to be false. It's commonly used during debugging to make the program fail more obviously if an unexpected condition occurs.

For example:

assert(length >= 0);  // die if length is negative.

You can also add a more informative message to be displayed if it fails like so:

assert(length >= 0 && "Whoops, length can't possibly be negative! (didn't we just check 10 lines ago?) Tell jsmith");

Or else like this:

assert(("Length can't possibly be negative! Tell jsmith", length >= 0));

When you're doing a release (non-debug) build, you can also remove the overhead of evaluating assert statements by defining the NDEBUG macro, usually with a compiler switch. The corollary of this is that your program should never rely on the assert macro running.

// BAD
assert(x++);

// GOOD
assert(x);    
x++;

// Watch out! Depends on the function:
assert(foo());

// Here's a safer way:
int ret = foo();
assert(ret);

From the combination of the program calling abort() and not being guaranteed to do anything, asserts should only be used to test things that the developer has assumed rather than, for example, the user entering a number rather than a letter (which should be handled by other means).

What about :

Map<String, String> s = Collections.emptyMap();

Create a setOptionsTitle() method and set a field in your class. Such as:

String bedStatus = "Set to 'Out of Bed'";

...

public void setOptionsTitle(String status)
{
    bedStatus = status;

}

Now when the menu gets populated, change the title to whatever your status is:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);

        menu.add(bedStatus);


        // Return true so that the menu gets displayed.
        return true;
    }

You Can Use The Simplest Method

<?php
function make_thumb($src, $dest, $desired_width) {

    /* read the source image */
    $source_image = imagecreatefromjpeg($src);
    $width = imagesx($source_image);
    $height = imagesy($source_image);

    /* find the "desired height" of this thumbnail, relative to the desired width  */
    $desired_height = floor($height * ($desired_width / $width));

    /* create a new, "virtual" image */
    $virtual_image = imagecreatetruecolor($desired_width, $desired_height);

    /* copy source image at a resized size */
    imagecopyresampled($virtual_image, $source_image, 0, 0, 0, 0, $desired_width, $desired_height, $width, $height);

    /* create the physical thumbnail image to its destination */
    imagejpeg($virtual_image, $dest);
}

$src="1494684586337H.jpg";
$dest="new.jpg";
$desired_width="200";
make_thumb($src, $dest, $desired_width);
?>

You want a check constraint.

CHECK constraints determine the valid values from a logical expression that is not based on data in another column. For example, the range of values for a salary column can be limited by creating a CHECK constraint that allows for only data that ranges from $15,000 through $100,000. This prevents salaries from being entered beyond the regular salary range.

You want something like:

ALTER TABLE dbo.Table ADD CONSTRAINT CK_Table_Frequency
    CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))

You can also implement check constraints with scalar functions, as described in the link above, which is how I prefer to do it.

foo.ToArray().Aggregate((a, b) => (a + "," + b)).ToString()

or

string.Concat(foo.ToArray().Select(a => a += ",").ToArray())

Updating, as this is extremely old. You should, of course, use string.Join now. It didn't exist as an option at the time of writing.

For me the problem was caused by a gradle.properties file in the list of Gradle scripts. It showed as gradle.properties (global) and refered to a file in C:\users\.gradle\gradle.properties. I right-clicked on it and selected delete from the menu to delete it. It deleted the file from the hard disk and my project now builds and runs. I guess that the global file was overwriting something that was used to locate the package android.support

How about something like this ...

var l1 = new List<int>() { 1,2,3,4,5,2,2,2,4,4,4,1 };

var g = l1.GroupBy( i => i );

foreach( var grp in g )
{
  Console.WriteLine( "{0} {1}", grp.Key, grp.Count() );
}

Edit per comment: I will try and do this justice. :)

In my example, it's a Func<int, TKey> because my list is ints. So, I'm telling GroupBy how to group my items. The Func takes a int and returns the the key for my grouping. In this case, I will get an IGrouping<int,int> (a grouping of ints keyed by an int). If I changed it to (i => i.ToString() ) for example, I would be keying my grouping by a string. You can imagine a less trivial example than keying by "1", "2", "3" ... maybe I make a function that returns "one", "two", "three" to be my keys ...

private string SampleMethod( int i )
{
  // magically return "One" if i == 1, "Two" if i == 2, etc.
}

So, that's a Func that would take an int and return a string, just like ...

i =>  // magically return "One" if i == 1, "Two" if i == 2, etc. 

But, since the original question called for knowing the original list value and it's count, I just used an integer to key my integer grouping to make my example simpler.

Your stored procedure is designed to accept a single parameter, Arg1List. You can't pass 4 parameters to a procedure that only accepts one.

To make it work, the code that calls your procedure will need to concatenate your parameters into a single string of no more than 3000 characters and pass it in as a single parameter.

Permission denied

In order to run a script the file must have an executable permission bit set.

In order to fully understand Linux file permissions you can study the documentation for the chmod command. chmod, an abbreviation of change mode, is the command that is used to change the permission settings of a file.

To read the chmod documentation for your local system , run man chmod or info chmod from the command line. Once read and understood you should be able to understand the output of running ...

ls -l foo.sh

... which will list the READ, WRITE and EXECUTE permissions for the file owner, the group owner and everyone else who is not the file owner or a member of the group to which the file belongs (that last permission group is sometimes referred to as "world" or "other")

Here's a summary of how to troubleshoot the Permission Denied error in your case.

$ ls -l foo.sh                    # Check file permissions of foo
-rw-r--r-- 1 rkielty users 0 2012-10-21 14:47 foo.sh 
    ^^^ 
 ^^^ | ^^^   ^^^^^^^ ^^^^^
  |  |  |       |       | 
Owner| World    |       |
     |          |    Name of
   Group        |     Group
             Name of 
              Owner 

Owner has read and write access rw but the - indicates that the executable permission is missing

The chmod command fixes that. (Group and other only have read permission set on the file, they cannot write to it or execute it)

$ chmod +x foo.sh               # The owner can set the executable permission on foo.sh
$ ls -l foo.sh                  # Now we see an x after the rw 
-rwxr-xr-x 1 rkielty users 0 2012-10-21 14:47 foo.sh
   ^  ^  ^

foo.sh is now executable as far as Linux is concerned.

Using sudo results in Command not found

When you run a command using sudo you are effectively running it as the superuser or root.

The reason that the root user is not finding your command is likely that the PATH environment variable for root does not include the directory where foo.sh is located. Hence the command is not found.

The PATH environment variable contains a list of directories which are searched for commands. Each user sets their own PATH variable according to their needs. To see what it is set to run

env | grep ^PATH

Here's some sample output of running the above env command first as an ordinary user and then as the root user using sudo

rkielty@rkielty-laptop:~$ env | grep ^PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

rkielty@rkielty-laptop:~$ sudo env | grep ^PATH
[sudo] password for rkielty: 
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

Note that, although similar, in this case the directories contained in the PATH the non-privileged user (rkielty) and the super user are not the same.

The directory where foo.sh resides is not present in the PATH variable of the root user, hence the command not found error.

It should be as simple as using a list of receiving variables:

scanf("%i %i %i", &var1, &var2, &var3);

final: final is a keyword. The variable decleared as final should be initialized only once and cannot be changed. Java classes declared as final cannot be extended. Methods declared as final cannot be overridden.

finally: finally is a block. The finally block always executes when the try block exits. This ensures that the finally block is executed even if an unexpected exception occurs. But finally is useful for more than just exception handling - it allows the programmer to avoid having cleanup code accidentally bypassed by a return, continue, or break. Putting cleanup code in a finally block is always a good practice, even when no exceptions are anticipated.

finalize: finalize is a method. Before an object is garbage collected, the runtime system calls its finalize() method. You can write system resources release code in finalize() method before getting garbage collected.

Under the job workspace folder, like:

there is a file named nextBuildNumber.

Setting the build number in the file and reloading the configuration from disk (Manage Jenkins menu) will force the next build you start to have the value from the file as BUILD_NUMBER.

A Relation object passes unknown method calls through to an Eloquent query Builder, which is set up to only select the related objects. That Builder in turn passes unknown method calls through to its underlying query Builder.

This means you can use the exists() or count() methods directly from a relation object:

$model->relation()->exists(); // bool: true if there is at least one row
$model->relation()->count(); // int: number of related rows

Note the parentheses after relation: ->relation() is a function call (getting the relation object), as opposed to ->relation which a magic property getter set up for you by Laravel (getting the related object/objects).

Using the count method on the relation object (that is, using the parentheses) will be much faster than doing $model->relation->count() or count($model->relation) (unless the relation has already been eager-loaded) since it runs a count query rather than pulling all of the data for any related objects from the database, just to count them. Likewise, using exists doesn't need to pull model data either.

Both exists() and count() work on all relation types I've tried, so at least belongsTo, hasOne, hasMany, and belongsToMany.

This worked for me

You can extend the gallery and use some flag to disable scrolling when you want:

public class MyGallery extends Gallery {

public boolean canScroll;

public MyGallery(Context context, AttributeSet attrs) {
    canScroll = true;
    super(context, attrs);
}

public void setCanScroll(boolean flag)
{
    canScroll = flag;
}

@Override
public boolean onScroll(android.view.MotionEvent e1, android.view.MotionEvent e2, float distanceX, float distanceY) {
    if (canScroll)
        return super.onScroll(e1,e2,distancex,distancey);
    else
        return false;
}

@Override
public boolean onSingleTapUp(MotionEvent e)
{
    if (canScroll)
        return super.onSingleTapUp(ey);
    else
        return false;
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
{
    if (canScroll)
        return super.onFling(e1,e2,velocityX,velocityY);
    else
        return false;
}
}

Unfortunately reflection to get attributes on enums is quite slow:

See this question: Anyone know a quick way to get to custom attributes on an enum value?

The .ToString() is quite slow on enums too.

You can write extension methods for enums though:

public static string GetName( this MyEnum input ) {
    switch ( input ) {
        case MyEnum.WINDOWSAUTHENTICATION:
            return "Windows";
        //and so on
    }
}

This isn't great, but will be quick and not require the reflection for attributes or field name.

C#6 Update

If you can use C#6 then the new nameof operator works for enums, so nameof(MyEnum.WINDOWSAUTHENTICATION) will be converted to "WINDOWSAUTHENTICATION" at compile time, making it the quickest way to get enum names.

Note that this will convert the explicit enum to an inlined constant, so it doesn't work for enums that you have in a variable. So:

nameof(AuthenticationMethod.FORMS) == "FORMS"

But...

var myMethod = AuthenticationMethod.FORMS;
nameof(myMethod) == "myMethod"

My json file was formatted exactly as the one in the question but none of the solutions here worked out. Finally I found a workaround on another Stackoverflow thread. Since this post is the first link in Google search, I put the that answer here so that other people come to this post in the future will find it more easily.

As it's been said there the valid json file needs "[" in the beginning and "]" in the end of file. Moreover, after each json item instead of "}" there must be a "},". All brackets without quotations! This piece of code just modifies the malformed json file into its correct format.

I'm thinking something like, just give an idea, to convert the column to string, and work with string is easier. however this does not work with strings containing numbers, like bad123. and ~ is taking the complement of selection.

df['a'] = df['a'].astype(str)
df[~df['a'].str.contains('0|1|2|3|4|5|6|7|8|9')]
df['a'] = df['a'].astype(object)

and using '|'.join([str(i) for i in range(10)]) to generate '0|1|...|8|9'

or using np.isreal() function, just like the most voted answer

df[~df['a'].apply(lambda x: np.isreal(x))]

Create a new file, and then on the filename use slash. For example

Java/Helloworld.txt

There is one thing to remember, when you are searching the object in array on the basis of more than one condition then use $elemMatch

Person.update(
   {
     _id: 5,
     grades: { $elemMatch: { grade: { $lte: 90 }, mean: { $gt: 80 } } }
   },
   { $set: { "grades.$.std" : 6 } }
)

here is the docs

Use the queryset object update method:

MyModel.objects.filter(pk=some_value).update(field1='some value')

Remember to include System.Diagnostics

ProcessStartInfo startInfo = new ProcessStartInfo("myfile.exe");        // exe file
startInfo.WorkingDirectory = @"C:\..\MyFile\bin\Debug\netcoreapp3.1\"; // exe folder

//here you add your arguments
startInfo.ArgumentList.Add("arg0");       // First argument          
startInfo.ArgumentList.Add("arg2");       // second argument
startInfo.ArgumentList.Add("arg3");       // third argument
Process.Start(startInfo);                 

From the AWS documentation:

Amazon SNS allows applications to send time-critical messages to multiple subscribers through a “push” mechanism, eliminating the need to periodically check or “poll” for updates.

Amazon SQS is a message queue service used by distributed applications to exchange messages through a polling model, and can be used to decouple sending and receiving components—without requiring each component to be concurrently available.

The paramount characteristic of functional programming, IMHO, is that you are programming with nothing but expressions -- expressions within expressions within expressions that all evaluate to the last, final expression that "warms the machine when evaluated".

The paramount characteristic of object-oriented programming, IMHO is that you are programming with objects that have internal state. You cannot have internal state in pure functions -- object-oriented programming languages need statements to make things happen. (There are no statements in functional programming.)

You are comparing apples to oranges. The patterns of object-oriented programming do not apply to function programming, because functional programming is programming with expressions, and object-oriented programming is programming with internal state.

If you have your problem in production, you must have V2__create_shipwreck.sql identically to the one you have in your latest version where it has not been modified.

Then the checksum will be correct again

First we need to parse the JSON object and then we can add an item.

var str = '{"theTeam":[{"teamId":"1","status":"pending"},
{"teamId":"2","status":"member"},{"teamId":"3","status":"member"}]}';

var obj = JSON.parse(str);
obj['theTeam'].push({"teamId":"4","status":"pending"});
str = JSON.stringify(obj);

Finally we JSON.stringify the obj back to JSON

What you are after is called partial function application.

Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.

Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:

Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.

This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?

Example:

var fr = partial(f, 1, 2, 3);

// now, when you invoke fr() it will invoke f(1,2,3)
fr();

Again, see that question for the details.

I have this problem from time to time. The thing that resolves the issue most for me is to run the JUnit test from Run configurations... ensuring that JUnit 4 is set as the test runner.

Generally, I see this issue when attempting to Run As... Junit test from the context menu on the Package Explorer. If you right click the code for the test you are trying to run and instead of selecting Run As... Junit Test you select Run configurations... ensure the Project, Test Class and test runner are set correctly, clicking apply, then run works all the time for me.

I'm not an attorney, but clicking the like button without the express permission of a facebook user might be a violation of facebook policy. You should have your corporate attorney check out the facebook policy.

You should encode the url to a page with a like button, so when scanned by the phone, it opens up a browser window to the like page, where now the user has the option to like it or not.

Use the jQuery hotkeys plugin and this code

jQuery(document).bind('keydown', 'shift+enter', 
         function (evt){ 
             $('textarea').val($('#textarea').val() + "\n");// use the right id here
             return true;
         }
);

Whenever you create or update package name Make sure your package name is exactly the same [Upper case and lower case matters]

Do below step.

1). Check applicationId in App level gradle file,

2). Check package_name in your google-services.json file,

3). Check package in your AndroidManifest file

and for full confirmation make sure that your working package directory name i.e.("com.example.app") is also the same.

SELECT COUNT(ID) FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For count


SELECT ID FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For results

you can try this indside findall for loop:

item_price = item.find('span', attrs={'class':'s-item__price'}).text

it extracts only text and assigs it to "item_pice"

You can use values() method:

For instance Status.values()[0] will return PAUSE in your case, if you print it, toString() will be called and "PAUSE" will be printed.

Since PHP/5.4.0, there is an option called JSON_UNESCAPED_UNICODE. Check it out:

Therefore you should try:

json_encode( $text, JSON_UNESCAPED_UNICODE );

The other answers do a good job of explaining what effect the [ChildActionOnly] attribute has. However, in most examples, I kept asking myself why I'd create a new action method just to render a partial view, within another view, when you could simply render @Html.Partial("_MyParialView") directly in the view. It seemed like an unnecessary layer. However, as I investigated, I found that one benefit is that the child action can create a different model and pass that to the partial view. The model needed for the partial might not be available in the model of the view in which the partial view is being rendered. Instead of modifying the model structure to get the necessary objects/properties there just to render the partial view, you can call the child action and have the action method take care of creating the model needed for the partial view.

This can come in handy, for example, in _Layout.cshtml. If you have a few properties common to all pages, one way to accomplish this is use a base view model and have all other view models inherit from it. Then, the _Layout can use the base view model and the common properties. The downside (which is subjective) is that all view models must inherit from the base view model to guarantee that those common properties are always available. The alternative is to render @Html.Action in those common places. The action method would create a separate model needed for the partial view common to all pages, which would not impact the model for the "main" view. In this alternative, the _Layout page need not have a model. It follows that all other view models need not inherit from any base view model.

I'm sure there are other reasons to use the [ChildActionOnly] attribute, but this seems like a good one to me, so I thought I'd share.

Truncate Pipe with optional params:

• limit - string max length
• completeWords - Flag to truncate at the nearest complete word, instead of character
• ellipsis - appended trailing suffix

-

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'truncate'
})
export class TruncatePipe implements PipeTransform {
  transform(value: string, limit = 25, completeWords = false, ellipsis = '...') {
    if (completeWords) {
      limit = value.substr(0, limit).lastIndexOf(' ');
    }
    return value.length > limit ? value.substr(0, limit) + ellipsis : value;
  }
}

Don't forget to add a module entry.

@NgModule({
  declarations: [
    TruncatePipe
  ]
})
export class AppModule {}

Usage

Example String:

public longStr = 'A really long string that needs to be truncated';

Markup:

  <h1>{{longStr | truncate }}</h1> 
  <!-- Outputs: A really long string that... -->

  <h1>{{longStr | truncate : 12 }}</h1> 
  <!-- Outputs: A really lon... -->

  <h1>{{longStr | truncate : 12 : true }}</h1> 
  <!-- Outputs: A really... -->

  <h1>{{longStr | truncate : 12 : false : '***' }}</h1> 
  <!-- Outputs: A really lon*** -->

Try this:

var isPalindrome = function (string) {
    if (string == string.split('').reverse().join('')) {
        alert(string + ' is palindrome.');
    }
    else {
        alert(string + ' is not palindrome.');
    }
}

document.getElementById('form_id').onsubmit = function() {
   isPalindrome(document.getElementById('your_input').value);
}

So this script alerts the result, is it palindrome or not. You need to change the your_id with your input id and form_id with your form id to get this work.

Radu Simionescu - awesome work! and below Your solution for Swift lovers:

@IBAction func showSecondControlerAndCloseCurrentOne(sender: UIButton) {
    let secondViewController = storyboard?.instantiateViewControllerWithIdentifier("ConrollerStoryboardID") as UIViewControllerClass // change it as You need it
    var presentingVC = self.presentingViewController

}

You will need to run the lsnrctl utility on server A to start the listener. You would then connect from computer B using the following syntax:

sqlplus username/password@hostA:1521 /XE

The port information is optional if the default of 1521 is used.

I am using node version manager. I was getting this error message because I had switched to a different version of node. When I switched back to the version of node where I installed bower, this error went away. In my case, the command was nvm use stable

use: opener.document.<id of document>.innerHTML = xmlhttp.responseText;

You can try this:

<?php 
    $feat_image = wp_get_attachment_url(get_post_thumbnail_id($post->ID)); 
    echo $feat_image; 
?>

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

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

Try this,

settings.py

# typically, os.path.join(os.path.dirname(__file__), 'media')
MEDIA_ROOT = '<your_path>/media'
MEDIA_URL = '/media/'

urls.py

urlpatterns = patterns('',
               (r'^media/(?P<path>.*)$', 'django.views.static.serve',
                 {'document_root': settings.MEDIA_ROOT}),
              )

.html

<img src="{{ MEDIA_URL }}<sub-dir-under-media-if-any>/<image-name.ext>" />

Caveat

Beware! using Context() will yield you an empty value for {{MEDIA_URL}}. You must use RequestContext(), instead.

I hope, this will help.

Create a table with the set you want to export and then use the command line utility pg_dump to export to a file:

create table export_table as 
select id, name, city
from nyummy.cimory
where city = 'tokyo'

$ pg_dump --table=export_table --data-only --column-inserts my_database > data.sql

--column-inserts will dump as insert commands with column names.

--data-only do not dump schema.

As commented below, creating a view in instead of a table will obviate the table creation whenever a new export is necessary.

There are other differences. For instance, {'time': datetime.now()} cannot be serialized to JSON, but can be converted to string. You should use one of these tools depending on the purpose (i.e. will the result later be decoded).

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

It must work.

But as Günter Zöchbauer said there must be some other problem in template. I have created kinda Relevant-Plunkr-Answer. Pleas do check browser's console.

boot.ts

@Component({
selector: 'my-app'
, template: `<div> <h1> BodyContent </h1></div>

      <filter></filter>

      <button (click)="onClickSidebar()">Click Me</button>
  `
, directives: [FilterTiles] 
})


export class BodyContent {
    @ViewChild(FilterTiles) ft:FilterTiles;

    public onClickSidebar() {
        console.log(this.ft);

        this.ft.tiles.push("entered");
    } 
}

filterTiles.ts

@Component({
     selector: 'filter',
    template: '<div> <h4>Filter tiles </h4></div>'
 })


 export class FilterTiles {
     public tiles = [];

     public constructor(){};
 }

It works like a charm. Please double check your tags and references.

Thanks...

gc() can help

saving data as .RData, closing, re-opening R, and loading the RData can help.

see my answer here: https://stackoverflow.com/a/24754706/190791 for more details

To me it sounds like the simplest way to expose your git repository on the server (which seems to be a Windows machine) would be to share it as a network resource.

Right click the folder "MY_GIT_REPOSITORY" and select "Sharing". This will give you the ability to share your git repository as a network resource on your local network. Make sure you give the correct users the ability to write to that share (will be needed when you and your co-workers push to the repository).

The URL for the remote that you want to configure would probably end up looking something like file://\\\\189.14.666.666\MY_GIT_REPOSITORY

If you wish to use any other protocol (e.g. HTTP, SSH) you'll have to install additional server software that includes servers for these protocols. In lieu of these the file sharing method is probably the easiest in your case right now.

If you also want to preserve the original file name, try with:

wget --content-disposition --trust-server-names -i list_of_urls.txt

Add this code in css:

 select, input[type="text"]{
      width:100%;
      box-sizing:border-box;
    }

In php you can check like below :

Specifying encoding list explicitly :

php -r "echo 'probably : ' . mb_detect_encoding(file_get_contents('myfile.txt'), 'UTF-8, ASCII, JIS, EUC-JP, SJIS, iso-8859-1') . PHP_EOL;"

More accurate "mb_list_encodings":

php -r "echo 'probably : ' . mb_detect_encoding(file_get_contents('myfile.txt'), mb_list_encodings()) . PHP_EOL;"

Here in first example, you can see that i put a list of encodings (detect list order) that might be matching. To have more accurate result you can use all possible encodings via : mb_list_encodings()

Note mb_* functions require php-mbstring

apt-get install php-mbstring

None of these options worked for me on Ubuntu 12.10 (yeah, I need to upgrade). However, I found an easy solution. Download the source from here: https://github.com/miracle2k/android-platform_sdk/blob/master/emulator/mksdcard/mksdcard.c. Then simply compile with "gcc mksdcard.c -o mksdcard". Backup mksdcard in the SDK tools subfolder and replace with the newly compiled one. Android Studio will now be happy with your SDK.

There is no tuple type in Go, and you are correct, the multiple values returned by functions do not represent a first-class object.

Nick's answer shows how you can do something similar that handles arbitrary types using interface{}. (I might have used an array rather than a struct to make it indexable like a tuple, but the key idea is the interface{} type)

My other answer shows how you can do something similar that avoids creating a type using anonymous structs.

These techniques have some properties of tuples, but no, they are not tuples.

this bellow code gave me correct response

jar cvf MyJar.jar *.properties lib/*.jar -C bin .  

it added the (log4j) properties file, it added the jar files in lib. and then it went inside bin to retrieve the class files with package.

You can inject .properties as a map in your class using @Resource annotation.

If you are working with XML based configuration, then add below bean in your spring configuration file:

 <bean id="myProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
      <property name="location" value="classpath:your.properties"/>
 </bean>

For, Annotation based:

@Bean(name = "myProperties")
public static PropertiesFactoryBean mapper() {
        PropertiesFactoryBean bean = new PropertiesFactoryBean();
        bean.setLocation(new ClassPathResource(
                "your.properties"));
        return bean;
}

Then you can pick them up in your application as a Map:

@Resource(name = "myProperties")
private Map<String, String> myProperties;

It's called a Favicon, have a read.

<link rel="shortcut icon" href="http://www.example.com/myicon.ico"/>

You can use this neat tool to generate cross-browser compatible Favicons.

In user crontab (crontab -e) do not put the user field.

Correct cron is:

0-59 * * * * echo "Hello World"

Syntax with user field is for /etc/crontab only:

0-59 * * * * mollerhoj3 echo "Hello World"

The file you are looking for is at,

Microsoft VS Code\resources\app\extensions\theme-defaults\themes

on Windows and search for filename dark_vs.json to locate it on any other system.

Update:

With new versions of VSCode you don't need to hunt for the settings file to customize the theme. Now you can customize your color theme with the workbench.colorCustomizations and editor.tokenColorCustomizations user settings. Documentation on the matter can be found here.

To set ANDROID_HOME, variable, you need to know how you installed android dev setup.

If you don't know you can check if the following paths exist in your machine. Add the following to .bashrc, .zshrc, or .profile depending on what you use

If you installed with homebrew,

export ANDROID_HOME=/usr/local/opt/android-sdk

Check if this path exists:

If you installed android studio following the website,

export ANDROID_HOME=~/Library/Android/sdk

Finally add it to path:

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

If you're too lazy to open an editor do this:

echo "export ANDROID_HOME=~/Library/Android/sdk" >> ~/.bashrc
echo "export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools" >> ~/.bashrc

I solved it.

I used destroy instead close function (it doesn't make any sense), but it worked.

$(document).ready(function() {
$('#showTerms').click(function()
{
    $('#terms').css('display','inline');
    $('#terms').dialog({resizable: false,
        modal: true,
        width: 400,
        height: 450,
        overlay: { backgroundColor: "#000", opacity: 0.5 },
        buttons:{ "Close": function() { $(this).dialog('**destroy**'); } },
        close: function(ev, ui) { $(this).close(); },
    });         
});   
$('#form1 input#calendarTEST').datepicker({ dateFormat: 'MM d, yy' });
});

BOOL and BOOLEAN are synonyms of TINYINT(1). Zero is false, anything else is true. More information here.

For those who are looking for making TextField or TextFormField accept only numbers as input, try this code block :

for flutter 1.20 or newer versions

TextFormField(
              controller: _controller,
              keyboardType: TextInputType.number,
              inputFormatters: <TextInputFormatter>[
                FilteringTextInputFormatter.allow(RegExp(r'[0-9]')),
              ],
              decoration: InputDecoration(
                  labelText: "whatever you want",
                  hintText: "whatever you want",
                  icon: Icon(Icons.phone_iphone)))

for earlier versions of 1.20

TextFormField(
    controller: _controller,
    keyboardType: TextInputType.number,
    inputFormatters: <TextInputFormatter>[
        WhitelistingTextInputFormatter.digitsOnly
    ],
    decoration: InputDecoration(
        labelText:"whatever you want", 
        hintText: "whatever you want",
        icon: Icon(Icons.phone_iphone)
    )
)

What I'm missing in the other answers is a reference to how this relates to co- and contravariance and sub- and supertypes (that is, polymorphism) in general and to Java in particular. This may be well understood by the OP, but just in case, here it goes:

Covariance

If you have a class Automobile, then Car and Truck are their subtypes. Any Car can be assigned to a variable of type Automobile, this is well-known in OO and is called polymorphism. Covariance refers to using this same principle in scenarios with generics or delegates. Java doesn't have delegates (yet), so the term applies only to generics.

I tend to think of covariance as standard polymorphism what you would expect to work without thinking, because:

List<Car> cars;
List<Automobile> automobiles = cars;
// You'd expect this to work because Car is-a Automobile, but
// throws inconvertible types compile error.

The reason of the error is, however, correct: List<Car> does not inherit from List<Automobile> and thus cannot be assigned to each other. Only the generic type parameters have an inherit relationship. One might think that the Java compiler simply isn't smart enough to properly understand your scenario there. However, you can help the compiler by giving him a hint:

List<Car> cars;
List<? extends Automobile> automobiles = cars;   // no error

Contravariance

The reverse of co-variance is contravariance. Where in covariance the parameter types must have a subtype relationship, in contravariance they must have a supertype relationship. This can be considered as an inheritance upper-bound: any supertype is allowed up and including the specified type:

class AutoColorComparer implements Comparator<Automobile>
    public int compare(Automobile a, Automobile b) {
        // Return comparison of colors
    }

This can be used with Collections.sort:

public static <T> void sort(List<T> list, Comparator<? super T> c)

// Which you can call like this, without errors:
List<Car> cars = getListFromSomewhere();
Collections.sort(cars, new AutoColorComparer());

You could even call it with a comparer that compares objects and use it with any type.

When to use contra or co-variance?

A bit OT perhaps, you didn't ask, but it helps understanding answering your question. In general, when you get something, use covariance and when you put something, use contravariance. This is best explained in an answer to Stack Overflow question How would contravariance be used in Java generics?.

So what is it then with List<? extends Map<String, String>>

You use extends, so the rules for covariance applies. Here you have a list of maps and each item you store in the list must be a Map<string, string> or derive from it. The statement List<Map<String, String>> cannot derive from Map, but must be a Map.

Hence, the following will work, because TreeMap inherits from Map:

List<Map<String, String>> mapList = new ArrayList<Map<String, String>>();
mapList.add(new TreeMap<String, String>());

but this will not:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new TreeMap<String, String>());

and this will not work either, because it does not satisfy the covariance constraint:

List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new ArrayList<String>());   // This is NOT allowed, List does not implement Map

What else?

This is probably obvious, but you may have already noted that using the extends keyword only applies to that parameter and not to the rest. I.e., the following will not compile:

List<? extends Map<String, String>> mapList = new List<? extends Map<String, String>>();
mapList.add(new TreeMap<String, Element>())  // This is NOT allowed

Suppose you want to allow any type in the map, with a key as string, you can use extend on each type parameter. I.e., suppose you process XML and you want to store AttrNode, Element etc in a map, you can do something like:

List<? extends Map<String, ? extends Node>> listOfMapsOfNodes = new...;

// Now you can do:
listOfMapsOfNodes.add(new TreeMap<Sting, Element>());
listOfMapsOfNodes.add(new TreeMap<Sting, CDATASection>());

POSIX is a standard for operating systems that was supposed to make it easier to write cross-platform software. It's an especially big deal in the world of Unix.

try this

  <head>
  <script type="text/javascript">
  function validate() {
  if(myform.fname.value.length==0)
  {
   document.getElementById("error").innerHTML="this is invalid name ";
   document.myform.fname.value="";
   document.myform.fname.focus();

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

$(window).keypress("c", function(e) {
  if (!e.ctrlKey)

Sudo over SSH passing a password, no tty required:

You can use sudo over ssh without forcing ssh to have a pseudo-tty (without the use of the ssh "-t" switch) by telling sudo not to require an interactive password and to just grab the password off stdin. You do this by using the "-S" switch on sudo. This makes sudo listen for the password on stdin, and stop listening when it sees a newline.

Example 1 - Simple Remote Command

In this example, we send a simple whoami command:

$ ssh user@server cat \| sudo --prompt="" -S -- whoami << EOF
> <remote_sudo_password>
root

We're telling sudo not to issue a prompt, and to take its input from stdin. This makes the sudo password passing completely silent so the only response you get back is the output from whoami.

This technique has the benefit of allowing you to run programs through sudo over ssh that themselves require stdin input. This is because sudo is consuming the password over the first line of stdin, then letting whatever program it runs continue to grab stdin.

Example 2 - Remote Command That Requires Its Own stdin

In the following example, the remote command "cat" is executed through sudo, and we are providing some extra lines through stdin for the remote cat to display.

$ ssh user@server cat \| sudo --prompt="" -S -- "cat" << EOF
> <remote_sudo_password>
> Extra line1
> Extra line2
> EOF
Extra line1
Extra line2

The output demonstrates that the <remote_sudo_password> line is being consumed by sudo, and that the remotely executed cat is then displaying the extra lines.

An example of where this would be beneficial is if you want to use ssh to pass a password to a privileged command without using the command line. Say, if you want to mount a remote encrypted container over ssh.

Example 3 - Mounting a Remote VeraCrypt Container

In this example script, we are remotely mounting a VeraCrypt container through sudo without any extra prompting text:

#!/bin/sh
ssh user@server cat \| sudo --prompt="" -S -- "veracrypt --non-interactive --stdin --keyfiles=/path/to/test.key /path/to/test.img /mnt/mountpoint" << EOF
SudoPassword
VeraCryptContainerPassword
EOF

It should be noted that in all the command-line examples above (everything except the script) the << EOF construct on the command line will cause the everything typed, including the password, to be recorded in the local machine's .bash_history. It is therefore highly recommended that for real-world use you either use do it entirely through a script, like the veracrypt example above, or, if on the command line then put the password in a file and redirect that file through ssh.

Example 1a - Example 1 Without Local Command-Line Password

The first example would thus become:

$ cat text_file_with_sudo_password | ssh user@server cat \| sudo --prompt="" -S -- whoami
root

Example 2a - Example 2 Without Local Command-Line Password

and the second example would become:

$ cat text_file_with_sudo_password - << EOF | ssh va1der.net cat \| sudo --prompt="" -S -- cat
> Extra line1
> Extra line2
> EOF
Extra line1
Extra line2

Putting the password in a separate file is unnecessary if you are putting the whole thing in a script, since the contents of scripts do not end up in your history. It still may be useful, though, in case you want to allow users who should not see the password to execute the script.

request.getSession(true) and request.getSession() both do the same thing, but if we use request.getSession(false) it will return null if session object not created yet.

If you change your function definition to use a variable instead:

var get_page = func(url string) string {
    ...
}

You can override it in your tests:

func TestDownloader(t *testing.T) {
    get_page = func(url string) string {
        if url != "expected" {
            t.Fatal("good message")
        }
        return "something"
    }
    downloader()
}

Careful though, your other tests might fail if they test the functionality of the function you override!

The Go authors use this pattern in the Go standard library to insert test hooks into code to make things easier to test:

REST(REpresentational State Transfer)
REpresentational State of an Object is Transferred is REST i.e. we don't send Object, we send state of Object. REST is an architectural style. It doesn’t define so many standards like SOAP. REST is for exposing Public APIs(i.e. Facebook API, Google Maps API) over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP(Simple Object Access Protocol)
SOAP brings its own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each operation implement some business logic. Though SOAP is commonly referred to as web services this is misnomer. SOAP has a very little if anything to do with the Web. REST provides true Web services based on URIs and HTTP.

Why REST?

• Since REST uses standard HTTP it is much simpler in just about ever way.
• REST is easier to implement, requires less bandwidth and resources.
• REST permits many different data formats where as SOAP only permits XML.
• REST allows better support for browser clients due to its support for JSON.
• REST has better performance and scalability. REST reads can be cached, SOAP based reads cannot be cached.
• If security is not a major concern and we have limited resources. Or we want to create an API that will be easily used by other developers publicly then we should go with REST.
• If we need Stateless CRUD operations then go with REST.
• REST is commonly used in social media, web chat, mobile services and Public APIs like Google Maps.
• RESTful service return various MediaTypes for the same resource, depending on the request header parameter "Accept" as application/xml or application/json for POST and /user/1234.json or GET /user/1234.xml for GET.
• REST services are meant to be called by the client-side application and not the end user directly.
• ST in REST comes from State Transfer. You transfer the state around instead of having the server store it, this makes REST services scalable.

Why SOAP?

• SOAP is not very easy to implement and requires more bandwidth and resources.
• SOAP message request is processed slower as compared to REST and it does not use web caching mechanism.
• WS-Security: While SOAP supports SSL (just like REST) it also supports WS-Security which adds some enterprise security features.
• WS-AtomicTransaction: Need ACID Transactions over a service, you’re going to need SOAP.
• WS-ReliableMessaging: If your application needs Asynchronous processing and a guaranteed level of reliability and security. Rest doesn’t have a standard messaging system and expects clients to deal with communication failures by retrying.
• If the security is a major concern and the resources are not limited then we should use SOAP web services. Like if we are creating a web service for payment gateways, financial and telecommunication related work then we should go with SOAP as here high security is needed.

That's the reason not to put configuration into webapp.

As far as I know, there are no good ways to access files in webapp folder from the unit tests. You can put your configuration into src/main/resources instead, so that you can access it from your unit tests (as described in the docs), as well as from the webapp (using classpath: prefix in contextConfigLocation).

I strongly recommend using Java generics to specify what type of object is in that List, ie. List<Car>. If you have Cars and Trucks you can use a common superclass/interface like this List<Vehicle>.

However, you can use Spring's ReflectionUtils to make fields accessible, even if they are private like the below runnable example:

List<Object> list = new ArrayList<Object>();

list.add("some value");
list.add(3);

for(Object obj : list)
{
    Class<?> clazz = obj.getClass();

    Field field = org.springframework.util.ReflectionUtils.findField(clazz, "value");
    org.springframework.util.ReflectionUtils.makeAccessible(field);

    System.out.println("value=" + field.get(obj));
}

Running this has an output of:

value=[C@1b67f74
value=3

Follow these steps to reset password in Windows system

1. Stop Mysql service from task manager

2. Create a text file and paste the below statement

MySQL 5.7.5 and earlier:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yournewpassword');

MySQL 5.7.6 and later:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'yournewpassword';

3. Save as mysql-init.txt and place it in 'C' drive.

4. Open command prompt and paste the following

C:\> mysqld --init-file=C:\\mysql-init.txt

$('.toggle img').each(function(index) { 
    if($(this).attr('data-id') == '4')
    {
        $(this).attr('data-block', 'something');
        $(this).attr('src', 'something.jpg');
    }
});

or

$('.toggle img[data-id="4"]').attr('data-block', 'something');
$('.toggle img[data-id="4"]').attr('src', 'something.jpg');

InputMethodManager.SHOW_FORCED isn't good choice. If you use this setting you should manage hiding keyboard state. My suggestion is like this;

    public void showSoftKeyboard(View view) {
    InputMethodManager inputMethodManager = (InputMethodManager) getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
    view.requestFocus();
    inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
}

Also, you can focus on view (usually EditText) taking parameters it. This makes it a more useful function

You can find through below query :

 SELECT OBJECT_NAME (FK.referenced_object_id) 'Referenced Table',

      COL_NAME(FK.parent_object_id,FKC.parent_column_id) 'Referring Column'
     FROM sys.foreign_keys AS FK
             INNER JOIN sys.foreign_key_columns AS FKC 
                 ON FKC.constraint_object_id = FK.OBJECT_ID
     WHERE OBJECT_NAME (FK.referenced_object_id) = 'YourTableName'
     AND COL_NAME(FK.referenced_object_id, FKC.referenced_column_id) = 'YourColumnName'
     order by  OBJECT_NAME(FK.parent_object_id)

"Confirm" in Javascript stops the whole process until it gets a mouse response on its buttons. If that is what you are looking for, you can refer jquery-ui but if you have nothing running behind your process while receiving the response and you control the flow programatically, take a look at this. You will have to hard-code everything by yourself but you have complete command over customization. https://www.w3schools.com/howto/howto_css_modals.asp

1. git checkout master
2. git pull
3. git checkout feature_branch
4. git rebase master

You need to do a forceful push after rebasing against master

An adventage of use ExpectedException Rule (version 4.7) is that you can test exception message and not only the expected exception.

And using Matchers, you can test the part of message you are interested:

exception.expectMessage(containsString("income: -1000.0"));

I have today similar problem. But weirder.

Revelation

Eventually I used strace on curl and found that it was connection to nscd deamon.

connect(4, {sa_family=AF_LOCAL, sun_path="/var/run/nscd/socket"}, 110) = 0

Solution

I've restarted the nscd service (Name Service Cache Daemon) and it helped to solve this issue!

systemctl restart nscd.service

Here is an example of how to use ProcessBuilder to execute your remote application. Since you do not care about input/output and/or errors, you can do as follows:

List<String> args = new ArrayList<String>();
args.add ("script.bat"); // command name
args.add ("-option"); // optional args added as separate list items
ProcessBuilder pb = new ProcessBuilder (args);
Process p = pb.start();
p.waitFor();

the waitFor() method will wait until the process had ended before continuing. This method returns the error code of the process but, since you don't care about it, I didn't put it in the example.

input.replaceAll("[^0-9?!\\.]","")

This will ignore the decimal points.

eg: if you have an input as 445.3kg the output will be 445.3.

I had the same issue but finally it worked after storage clean on my mobile. May be happen because of insufficient storage

You can use IsNull function

select 
    isnull(rtrim(ltrim([FirstName]))+' ','') +
    isnull(rtrim(ltrim([SecondName]))+' ','') +
    isnull(rtrim(ltrim([Surname]))+' ','') +
    isnull(rtrim(ltrim([SecondSurname])),'')
from TableDat

if one column is null you would get an empty char

There are two issues here:

The first issue is, adding to an Collection after an Iterator is returned. As mentioned, there is no defined behavior when the underlying Collection is modified, as noted in the documentation for Iterator.remove:

... The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

The second issue is, even if an Iterator could be obtained, and then return to the same element the Iterator was at, there is no guarantee about the order of the iteratation, as noted in the Collection.iterator method documentation:

... There are no guarantees concerning the order in which the elements are returned (unless this collection is an instance of some class that provides a guarantee).

For example, let's say we have the list [1, 2, 3, 4].

Let's say 5 was added when the Iterator was at 3, and somehow, we get an Iterator that can resume the iteration from 4. However, there is no guarentee that 5 will come after 4. The iteration order may be [5, 1, 2, 3, 4] -- then the iterator will still miss the element 5.

As there is no guarantee to the behavior, one cannot assume that things will happen in a certain way.

One alternative could be to have a separate Collection to which the newly created elements can be added to, and then iterating over those elements:

Collection<String> list = Arrays.asList(new String[]{"Hello", "World!"});
Collection<String> additionalList = new ArrayList<String>();

for (String s : list) {
    // Found a need to add a new element to iterate over,
    // so add it to another list that will be iterated later:
    additionalList.add(s);
}

for (String s : additionalList) {
    // Iterate over the elements that needs to be iterated over:
    System.out.println(s);
}

Edit

Elaborating on Avi's answer, it is possible to queue up the elements that we want to iterate over into a queue, and remove the elements while the queue has elements. This will allow the "iteration" over the new elements in addition to the original elements.

Let's look at how it would work.

Conceptually, if we have the following elements in the queue:

[1, 2, 3, 4]

And, when we remove 1, we decide to add 42, the queue will be as the following:

[2, 3, 4, 42]

As the queue is a FIFO (first-in, first-out) data structure, this ordering is typical. (As noted in the documentation for the Queue interface, this is not a necessity of a Queue. Take the case of PriorityQueue which orders the elements by their natural ordering, so that's not FIFO.)

The following is an example using a LinkedList (which is a Queue) in order to go through all the elements along with additional elements added during the dequeing. Similar to the example above, the element 42 is added when the element 2 is removed:

Queue<Integer> queue = new LinkedList<Integer>();
queue.add(1);
queue.add(2);
queue.add(3);
queue.add(4);

while (!queue.isEmpty()) {
    Integer i = queue.remove();
    if (i == 2)
        queue.add(42);

    System.out.println(i);
}

The result is the following:

1
2
3
4
42

As hoped, the element 42 which was added when we hit 2 appeared.

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

The accepted answer of how to create an Index inline a Table creation script did not work for me. This did:

CREATE TABLE [dbo].[TableToBeCreated]
(
    [Id] BIGINT IDENTITY(1, 1) NOT NULL PRIMARY KEY
    ,[ForeignKeyId] BIGINT NOT NULL
    ,CONSTRAINT [FK_TableToBeCreated_ForeignKeyId_OtherTable_Id] FOREIGN KEY ([ForeignKeyId]) REFERENCES [dbo].[OtherTable]([Id])
    ,INDEX [IX_TableToBeCreated_ForeignKeyId] NONCLUSTERED ([ForeignKeyId])
)

Remember, Foreign Keys do not create Indexes, so it is good practice to index them as you will more than likely be joining on them.

Really late reply for me, but I just suffered the pain of this problem as well.

What fixed it for me (after trying the Axis label settings and intervals from those screens, none of which worked!) was select the Horizontal Axis, then when you can see all the properties find Labels, and change LabelInterval to 1.

For some reason when I set this from the pop up properties screens it either never 'stuck' or it changes a slightly different value that didn't fix my issue.

November 2020 Update

I searched for the top NodeJS html parser libraries.

Because my use cases didn't require a library with many features, I could focus on stability and performance.

By stability I mean that I want the library to be used long enough by the community in order to find bugs and that it will be still maintained and that open issues will be closed.

Its hard to understand the future of an open source library, but I did a small summary based on the top 10 libraries in openbase.

I divided into 2 groups according to the last commit (and on each group the order is according to Github starts):

Last commit is in the last 6 months:

jsdom - Last commit: 3 Months, Open issues: 331, Github stars: 14.9K.

htmlparser2 - Last commit: 8 days, Open issues: 2, Github stars: 2.7K.

parse5 - Last commit: 2 Months, Open issues: 21, Github stars: 2.5K.

swagger-parser - Last commit: 2 Months, Open issues: 48, Github stars: 663.

html-parse-stringify - Last commit: 4 Months, Open issues: 3, Github stars: 215.

node-html-parser - Last commit: 7 days, Open issues: 15, Github stars: 205.

Last commit is 6 months and above:

cheerio - Last commit: 1 year, Open issues: 174, Github stars: 22.9K.

koa-bodyparser - Last commit: 6 months, Open issues: 9, Github stars: 1.1K.

sax-js - Last commit: 3 Years, Open issues: 65, Github stars: 941.

draftjs-to-html - Last commit: 1 Year, Open issues: 27, Github stars: 233.

I picked Node-html-parser because it seems quiet fast and very active at this moment.

(*) Openbase adds much more information regarding each library like the number of contributors (with +3 commits), weekly downloads, Monthly commits, Version etc'.

(**) The table above is a snapshot according to the specific time and date - I would check the reference again and as a first step check the level of recent activity and then dive into the smaller details.

Style the left column with position: fixed. (You'll presumably want to use top and left styles to control where exactly it occurs.)

While some of those code-snippets are short and working, they aren't trivial to follow and understand.

As i am not a fan of "copy-paste" from stack-overflow, i would like developers to understand the code they are push into they software, hope you'll find the below useful.

DEMO: Resizing images with JS and HTML Canvas Demo fiddler.

You may find 3 different methods to do this resize, that will help you understand how the code is working and why.

https://jsfiddle.net/1b68eLdr/93089/

Full code of both demo, and TypeScript method that you may want to use in your code, can be found in the GitHub project.

https://github.com/eyalc4/ts-image-resizer

This is the final code:

export class ImageTools {
base64ResizedImage: string = null;

constructor() {
}

ResizeImage(base64image: string, width: number = 1080, height: number = 1080) {
    let img = new Image();
    img.src = base64image;

    img.onload = () => {

        // Check if the image require resize at all
        if(img.height <= height && img.width <= width) {
            this.base64ResizedImage = base64image;

            // TODO: Call method to do something with the resize image
        }
        else {
            // Make sure the width and height preserve the original aspect ratio and adjust if needed
            if(img.height > img.width) {
                width = Math.floor(height * (img.width / img.height));
            }
            else {
                height = Math.floor(width * (img.height / img.width));
            }

            let resizingCanvas: HTMLCanvasElement = document.createElement('canvas');
            let resizingCanvasContext = resizingCanvas.getContext("2d");

            // Start with original image size
            resizingCanvas.width = img.width;
            resizingCanvas.height = img.height;


            // Draw the original image on the (temp) resizing canvas
            resizingCanvasContext.drawImage(img, 0, 0, resizingCanvas.width, resizingCanvas.height);

            let curImageDimensions = {
                width: Math.floor(img.width),
                height: Math.floor(img.height)
            };

            let halfImageDimensions = {
                width: null,
                height: null
            };

            // Quickly reduce the dize by 50% each time in few iterations until the size is less then
            // 2x time the target size - the motivation for it, is to reduce the aliasing that would have been
            // created with direct reduction of very big image to small image
            while (curImageDimensions.width * 0.5 > width) {
                // Reduce the resizing canvas by half and refresh the image
                halfImageDimensions.width = Math.floor(curImageDimensions.width * 0.5);
                halfImageDimensions.height = Math.floor(curImageDimensions.height * 0.5);

                resizingCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                    0, 0, halfImageDimensions.width, halfImageDimensions.height);

                curImageDimensions.width = halfImageDimensions.width;
                curImageDimensions.height = halfImageDimensions.height;
            }

            // Now do final resize for the resizingCanvas to meet the dimension requirments
            // directly to the output canvas, that will output the final image
            let outputCanvas: HTMLCanvasElement = document.createElement('canvas');
            let outputCanvasContext = outputCanvas.getContext("2d");

            outputCanvas.width = width;
            outputCanvas.height = height;

            outputCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                0, 0, width, height);

            // output the canvas pixels as an image. params: format, quality
            this.base64ResizedImage = outputCanvas.toDataURL('image/jpeg', 0.85);

            // TODO: Call method to do something with the resize image
        }
    };
}}

You can also get control of grand parent index by the following code

$parent.$parent.$index

For WebAPI, here is the code to retrieve body text without going through their special [FromBody] binding.

public class YourController : ApiController
{
    [HttpPost]
    public HttpResponseMessage Post()
    {
        string bodyText = this.Request.Content.ReadAsStringAsync().Result;
        //more code here...
    }
}

The JSON format can contain only those types of value:

• string
• number
• object
• array
• true
• false
• null

An image is of the type "binary" which is none of those. So you can't directly insert an image into JSON. What you can do is convert the image to a textual representation which can then be used as a normal string.

The most common way to achieve that is with what's called base64. Basically, instead of encoding it as 1 and 0s, it uses a range of 64 characters which makes the textual representation of it more compact. So for example the number '64' in binary is represented as 1000000, while in base64 it's simply one character: =.

There are many ways to encode your image in base64 depending on if you want to do it in the browser or not.

Note that if you're developing a web application, it will be way more efficient to store images separately in binary form, and store paths to those images in your JSON or elsewhere. That also allows your client's browser to cache the images.

I'd like to illustrate how the three terms are implemented in Rails. ActiveRecord calls any type of relationship between two models an association. One would not find very often the terms composition and aggregation, when reading documentation or articles, related to ActiveRecord. An association is created by adding one of the association class macros to the body of the class. Some of these macros are belongs_to, has_one, has_many etc..

If we want to set up a composition or aggregation, we need to add belongs_to to the owned model (also called child) and has_one or has_many to the owning model (also called parent). Wether we set up composition or aggregation depends on the options we pass to the belongs_to call in the child model. Prior to Rails 5, setting up belongs_to without any options created an aggregation, the child could exist without a parent. If we wanted a composition, we needed to explicitly declare this by adding the option required: true:

class Room < ActiveRecord::Base
  belongs_to :house, required: true
end

In Rails 5 this was changed. Now, declaring a belongs_to association creates a composition by default, the child cannot exist without a parent. So the above example can be re-written as:

class Room < ApplicationRecord
  belongs_to :house
end

If we want to allow the child object to exist without a parent, we need to declare this explicitly via the option optional

class Product < ApplicationRecord
  belongs_to :category, optional: true
end

Instance methods need to be called from an instance. Your setLoanItem method is an instance method (it doesn't have the modifier static), which it needs to be in order to function (because it is setting a value on the instance that it's called on (this)).

You need to create an instance of the class before you can call the method on it:

Media media = new Media();
media.setLoanItem("Yes");

(Btw it would be better to use a boolean instead of a string containing "Yes".)

To build on Louis's helpful answer...

Setting the User Agent in PhantomJS

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
...
caps = DesiredCapabilities.PHANTOMJS
caps["phantomjs.page.settings.userAgent"] = "whatever you want"
driver = webdriver.PhantomJS(desired_capabilities=caps)

The only minor issue is that, unlike for Firefox and Chrome, this does not return your custom setting:

driver.execute_script("return navigator.userAgent")

So, if anyone figures out how to do that in PhantomJS, please edit my answer or add a comment below! Cheers.

If you are talking about an RCP app, then what you need is the SWT link widget.

Here is the official link event handler snippet.

Update

Here is minimalist android application to connect to either superuser or stackoverflow with 2 buttons.

package ap.android;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;

public class LinkButtons extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    public void goToSo (View view) {
        goToUrl ( "http://stackoverflow.com/");
    }

    public void goToSu (View view) {
        goToUrl ( "http://superuser.com/");
    }

    private void goToUrl (String url) {
        Uri uriUrl = Uri.parse(url);
        Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
        startActivity(launchBrowser);
    }

}

And here is the layout.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent">
    <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/select" />
    <Button android:layout_height="wrap_content" android:clickable="true" android:autoLink="web" android:cursorVisible="true" android:layout_width="match_parent" android:id="@+id/button_so" android:text="StackOverflow" android:linksClickable="true" android:onClick="goToSo"></Button>
    <Button android:layout_height="wrap_content" android:layout_width="match_parent" android:text="SuperUser" android:autoLink="web" android:clickable="true" android:id="@+id/button_su" android:onClick="goToSu"></Button>
</LinearLayout>

If you are looking for 1st Number with decimal as string has correct decimal places, you may try regexp_substr function like this:

regexp_substr('stack12.345overflow', '\.*[[:digit:]]+\.*[[:digit:]]*')

In Firefox at least, the DOM inspector is telling me that the File input elements have a property called files. You should be able to check its length.

document.getElementById('myFileInput').files.length

In my view the perfect answer you must required is

var reader = new FileReader();

//Read the contents of Image File.
reader.readAsDataURL(fileUpload.files[0]);
reader.onload = function (e) {

  //Initiate the JavaScript Image object.
  var image = new Image();

  //Set the Base64 string return from FileReader as source.
  image.src = e.target.result;

  //Validate the File Height and Width.
  image.onload = function () {
    var height = this.height;
    var width = this.width;
    if (height > 100 || width > 100) {
      alert("Height and Width must not exceed 100px.");
      return false;
    }
    alert("Uploaded image has valid Height and Width.");
    return true;
  };
};

remove href attribute:

<a id="" onclick="f1()">jhhghj</a>

if link styles are important then:

<a href="javascript:void(f1())">jhhghj</a>

From my personal experience where we tryed to put the border red when an invalid entry was selected, it is impossible to put border red of select element in IE.

As stated before the ocntrols in internet explorer uses WindowsAPI to draw and render and you have nothing to solve this.

What was our solution was to put the background color of select element light red (for text to be readable). background color was working in every browser, but in IE we had a side effects that the element where the same background color as the select.

So to summarize the solution we putted :

select
{
  background-color:light-red;
  border: 2px solid red;
}
option
{
  background-color:white;
}

Note that color was set with hex code, I just don't remember which.

This solution was giving us the wanted effect in every browser except for the border red in IE.

Good luck

Works properly on Andorid 8.1:

Updated sample (without any deprecated code):

public NotificationBattery(Context context) {
    this.mCtx = context;

    mBuilder = new NotificationCompat.Builder(context, CHANNEL_ID)
            .setContentTitle(context.getString(R.string.notification_title_battery))
            .setSmallIcon(R.drawable.ic_launcher)
            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
            .setChannelId(CHANNEL_ID)
            .setOnlyAlertOnce(true)
            .setPriority(NotificationCompat.PRIORITY_MAX)
            .setWhen(System.currentTimeMillis() + 500)
            .setGroup(GROUP)
            .setOngoing(true);

    mRemoteViews = new RemoteViews(context.getPackageName(), R.layout.notification_view_battery);

    initBatteryNotificationIntent();

    mBuilder.setContent(mRemoteViews);

    mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    if (AesPrefs.getBooleanRes(R.string.SHOW_BATTERY_NOTIFICATION, true)) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(CHANNEL_ID, context.getString(R.string.notification_title_battery),
                    NotificationManager.IMPORTANCE_DEFAULT);
            channel.setShowBadge(false);
            channel.setSound(null, null);
            mNotificationManager.createNotificationChannel(channel);
        }
    } else {
        mNotificationManager.cancel(Const.NOTIFICATION_CLIPBOARD);
    }
}

Old snipped (it's a different app - not related to the code above):

@Override
public int onStartCommand(Intent intent, int flags, final int startId) {
    Log.d(TAG, "onStartCommand");

    String CHANNEL_ONE_ID = "com.kjtech.app.N1";
    String CHANNEL_ONE_NAME = "Channel One";
    NotificationChannel notificationChannel = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        notificationChannel = new NotificationChannel(CHANNEL_ONE_ID,
                CHANNEL_ONE_NAME, IMPORTANCE_HIGH);
        notificationChannel.enableLights(true);
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.setShowBadge(true);
        notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.createNotificationChannel(notificationChannel);
    }

    Bitmap icon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
    Notification notification = new Notification.Builder(getApplicationContext())
            .setChannelId(CHANNEL_ONE_ID)
            .setContentTitle(getString(R.string.obd_service_notification_title))
            .setContentText(getString(R.string.service_notification_content))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setLargeIcon(icon)
            .build();

    Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    notification.contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);

    startForeground(START_FOREGROUND_ID, notification);

    return START_STICKY;
}

Very easy, just use the SQLCMD-syntax.

Remember to enable SQLCMD-mode in the SSMS, look under Query -> SQLCMD Mode

Try execute:

!!DIR
!!:GO

or maybe:
!!DIR "c:/temp"
!!:GO

A duplicate post of sorts, but check out my solution for comparing collections. It's pretty simple:

This will perform an equality comparison regardless of order:

var list1 = new[] { "Bill", "Bob", "Sally" };
var list2 = new[] { "Bob", "Bill", "Sally" };
bool isequal = list1.Compare(list2).IsSame;

This will check to see if items were added / removed:

var list1 = new[] { "Billy", "Bob" };
var list2 = new[] { "Bob", "Sally" };
var diff = list1.Compare(list2);
var onlyinlist1 = diff.Removed; //Billy
var onlyinlist2 = diff.Added;   //Sally
var inbothlists = diff.Equal;   //Bob

This will see what items in the dictionary changed:

var original = new Dictionary<int, string>() { { 1, "a" }, { 2, "b" } };
var changed = new Dictionary<int, string>() { { 1, "aaa" }, { 2, "b" } };
var diff = original.Compare(changed, (x, y) => x.Value == y.Value, (x, y) => x.Value == y.Value);
foreach (var item in diff.Different)
  Console.Write("{0} changed to {1}", item.Key.Value, item.Value.Value);
//Will output: a changed to aaa

Original post here.

Try this:

Dim Lastrow As Integer
Lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row

Range("A2:L" & Lastrow).Select

Let's pretend that the value of Lastrow is 50. When you use the following:

Range("A2:L2" & Lastrow).Select

Then it is selecting a range from A2 to L250.

This process preserve history, but is little workarround:

# make branchs to new files
$: git mv arquivos && git commit

# in original branch, remove original files
$: git rm arquivos && git commit

# do merge and fix conflicts
$: git merge branch-copia-arquivos

# back to original branch and revert commit removing files
$: git revert commit

It sounds like you're not instantiating your class. That's the primary reason I get the "an object reference is required" error.

MyClass myClass = new MyClass();

once you've added that line you can then call your method

myClass.myMethod();

Also, are all of your classes in the same namespace? When I was first learning c# this was a common tripping point for me.

This has been driving me insane for the past few days and couldn't get around it but have finally figured it out:

In my machine.config file I had an entry under <system.web>:

<deployment retail="true" />

This seems to override any other customError settings that you have specified in a web.config file, so setting the above entry to:

<deployment retail="false" />

now means that I can once again see the detailed error messages that I need to.

The machine.config is located at

32-bit

%windir%\Microsoft.NET\Framework\[version]\config\machine.config

64-bit

%windir%\Microsoft.NET\Framework64\[version]\config\machine.config 

Hope that helps someone out there and saves a few hours of hair-pulling.

// 24-hour time to 12-hour time 
$time_in_12_hour_format  = date("g:i a", strtotime("13:30"));

// 12-hour time to 24-hour time 
$time_in_24_hour_format  = date("H:i", strtotime("1:30 PM"));

AJAX file uploads are now possible by passing a FormData object to the data property of the $.ajax request.

As the OP specifically asked for a jQuery implementation, here you go:

<form id="upload" enctype="multipart/form-data" action="@Url.Action("JsonSave", "Survey")" method="POST">
    <input type="file" name="fileUpload" id="fileUpload" size="23" /><br />
    <button>Upload!</button>
</form>

$('#upload').submit(function(e) {
    e.preventDefault(); // stop the standard form submission

    $.ajax({
        url: this.action,
        type: this.method,
        data: new FormData(this),
        cache: false,
        contentType: false,
        processData: false,
        success: function (data) {
            console.log(data.UploadedFileCount + ' file(s) uploaded successfully');
        },
        error: function(xhr, error, status) {
            console.log(error, status);
        }
    });
});

public JsonResult Survey()
{
    for (int i = 0; i < Request.Files.Count; i++)
    {
        var file = Request.Files[i];
        // save file as required here...
    }
    return Json(new { UploadedFileCount = Request.Files.Count });
}

Adding this intent filter to one of the activities declared in app manifest fixed this for me.

<activity
    android:name=".MyActivity"
    android:screenOrientation="portrait"
    android:label="@string/app_name">

    <intent-filter>

       <action android:name="android.intent.action.VIEW" />

    </intent-filter>

</activity>

When you echo $array;, the result is Array, result[0] then represents the first character in Array which is A.

One way to handle this problem would be like this:

ajax.php

<?php
$array = array(1,2,3,4,5,6);
foreach($array as $a)
    echo $a.",";
?>

jquery code

$(function(){ /* short for $(document).ready(function(){ */

    $('#prev').click(function(){

        $.ajax({type:    'POST',
                 url:     'ajax.php',
                 data:    'id=testdata',
                 cache:   false,
                 success: function(data){
                     var tmp = data.split(",");
                     $('#content1').html(tmp[0]);
                 }
                });
    });

});

You can use

SELECT SYS_EXTRACT_UTC(TIMESTAMP '2000-03-28 11:30:00.00 -02:00') FROM DUAL;

You may also need to change your timezone

ALTER SESSION SET TIME_ZONE = 'Europe/Berlin';

Or read it

SELECT SESSIONTIMEZONE, CURRENT_TIMESTAMP FROM dual;

I got a solution that plays nice with bodyParser, using the verify callback in bodyParser. In this code, I am using it to get a sha1 of the content and also getting the raw body.

app.use(bodyParser.json({
    verify: function(req, res, buf, encoding) {

        // sha1 content
        var hash = crypto.createHash('sha1');
        hash.update(buf);
        req.hasha = hash.digest('hex');
        console.log("hash", req.hasha);

        // get rawBody        
        req.rawBody = buf.toString();
        console.log("rawBody", req.rawBody);

    }
}));

I am new in Node.js and express.js (started yesterday, literally!) so I'd like to hear comments on this solution.

EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable example does not need the mappedBy annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:

org.hibernate.AnnotationException: 
   Associations marked as mappedBy must not define database mappings 
   like @JoinTable or @JoinColumn

Let's pretend that you have an entity named Project and another entity named Task and each project can have many tasks.

You can design the database schema for this scenario in two ways.

The first solution is to create a table named Project and another table named Task and add a foreign key column to the task table named project_id:

Project      Task
-------      ----
id           id
name         name
             project_id

This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:

@Entity
public class Project {

   @OneToMany(mappedBy = "project")
   private Collection<Task> tasks;

}

@Entity
public class Task {

   @ManyToOne
   private Project project;

}

The other solution is to use a third table, e.g. Project_Tasks, and store the relationship between projects and tasks in that table:

Project      Task      Project_Tasks
-------      ----      -------------
id           id        project_id
name         name      task_id

The Project_Tasks table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:

Project entity:

@Entity
public class Project {

    @Id
    @GeneratedValue
    private Long pid;

    private String name;

    @JoinTable
    @OneToMany
    private List<Task> tasks;

    public Long getPid() {
        return pid;
    }

    public void setPid(Long pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

Task entity:

@Entity
public class Task {

    @Id
    @GeneratedValue
    private Long tid;

    private String name;

    public Long getTid() {
        return tid;
    }

    public void setTid(Long tid) {
        this.tid = tid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

This will create the following database structure:

The @JoinTable annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks property like this:

@JoinTable(
        name = "MY_JT",
        joinColumns = @JoinColumn(
                name = "PROJ_ID",
                referencedColumnName = "PID"
        ),
        inverseJoinColumns = @JoinColumn(
                name = "TASK_ID",
                referencedColumnName = "TID"
        )
)
@OneToMany
private List<Task> tasks;

The resulting database would have become:

Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.

The key to all of this is understanding map projections. As others have pointed out, the cause of the distortion is the fact that the spherical (or more accurately ellipsoidal) earth is projected onto a plane.

In order to achieve your goal, you first must know two things about your data:

1. The projection your maps are in. If they are purely derived from Google Maps, then chances are they are using a spherical Mercator projection.
2. The geographic coordinate system your latitude/longitude coordinates are using. This can vary, because there are different ways of locating lat/longs on the globe. The most common GCS, used in most web-mapping applications and for GPS's, is WGS84.

I'm assuming your data is in these coordinate systems.

The spherical Mercator projection defines a coordinate pair in meters, for the surface of the earth. This means, for every lat/long coordinate there is a matching meter/meter coordinate. This enables you to do the conversion using the following procedure:

1. Find the WGS84 lat/long of the corners of the image.
2. Convert the WGS lat/longs to the spherical Mercator projection. There conversion tools out there, my favorite is to use the cs2cs tool that is part of the PROJ4 project.
3. You can safely do a simple linear transform to convert between points on the image, and points on the earth in the spherical Mercator projection, and back again.

In order to go from a WGS84 point to a pixel on the image, the procedure is now:

1. Project lat/lon to spherical Mercator. This can be done using the proj4js library.
2. Transform spherical Mercator coordinate into image pixel coordinate using the linear relationship discovered above.

You can use the proj4js library like this:

// include the library
<script src="lib/proj4js-combined.js"></script>  //adjust the path for your server
                                                 //or else use the compressed version
// creating source and destination Proj4js objects
// once initialized, these may be re-used as often as needed
var source = new Proj4js.Proj('EPSG:4326');    //source coordinates will be in Longitude/Latitude, WGS84
var dest = new Proj4js.Proj('EPSG:3785');     //destination coordinates in meters, global spherical mercators projection, see http://spatialreference.org/ref/epsg/3785/


// transforming point coordinates
var p = new Proj4js.Point(-76.0,45.0);   //any object will do as long as it has 'x' and 'y' properties
Proj4js.transform(source, dest, p);      //do the transformation.  x and y are modified in place

//p.x and p.y are now EPSG:3785 in meters

Edit:

The oracle tag was not on the question when this answer was offered, and apparently it doesn't work with oracle, but it does work with at least postgres and mysql

No, just use the value directly:

begin
  if (select count(*) from table) > 0 then
     update table
  end if;
end;

Note there is no need for an "else".

Edited

You can simply do it all within the update statement (ie no if construct):

update table
set ...
where ...
and exists (select 'x' from table where ...)

I got into this problem using Ubuntu, pyenv and Python 3.8.1 managed by pyenv. There was actually no way to get pip to work correctly, since every time I tried to install anything, including pip itself, the same error showed up. Final solution was to install, via pyenv, a newer version, in this case 3.8.6. Apparently, from 3.8.4 Python is prepared to run SSL/TLS out of the box, so everything worked fine.

We see this constantly, all over our app, using Crashlytics. The crash usually happens way down in platform code. A small sampling:

android.database.CursorWindow.finalize() timed out after 10 seconds

java.util.regex.Matcher.finalize() timed out after 10 seconds

android.graphics.Bitmap$BitmapFinalizer.finalize() timed out after 10 seconds

org.apache.http.impl.conn.SingleClientConnManager.finalize() timed out after 10 seconds

java.util.concurrent.ThreadPoolExecutor.finalize() timed out after 10 seconds

android.os.BinderProxy.finalize() timed out after 10 seconds

android.graphics.Path.finalize() timed out after 10 seconds

The devices on which this happens are overwhelmingly (but not exclusively) devices manufactured by Samsung. That could just mean that most of our users are using Samsung devices; alternately it could indicate a problem with Samsung devices. I'm not really sure.

I suppose this doesn't really answer your questions, but I just wanted to reinforce that this seems quite common, and is not specific to your application.

Try it like this:

.row-2 ul li {
    margin-top: 15px;
}

it is Cross-site scripting problem. Common modern browsers doesn't allow to send request to another url.

For me just running the below command is not enough (though a valid first step):

npm install -g typescript

The following command is what you need (I think deleting node_modules works too, but the below command is quicker)

npm link typescript

put only :

or die(mysqli_error());

after your query

and it will retern the error as echo

example

// "Your Query" means you can put "Select/Update/Delete/Set" queries here
$qfetch = mysqli_fetch_assoc(mysqli_query("your query")) or die(mysqli_error()); 



    if (mysqli_errno()) {
        echo 'error' . mysqli_error();
        die();
    }

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,

[ "$1" = 'yes' ] && [ -r $2.txt ]

The shell is evaluating the and condition. In your second case,

[ "$1" = 'yes' -a $2 -lt 3 ]

The test command (or builtin test) is evaluating the and condition.

Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:

[[ $1 == yes && -r $2.txt ]]

Which is more similar to modern programming languages and thus is more readable.

You are trying to read xls with explicit implementation poi classes for xlsx.

G:\Selenium Jar Files\TestData\Data.xls

Either use HSSFWorkbook and HSSFSheet classes or make your implementation more generic by using shared interfaces, like;

Change:

XSSFWorkbook workbook = new XSSFWorkbook(file);

To:

 org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(file);

And Change:

XSSFSheet sheet = workbook.getSheetAt(0);

To:

org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);

Why you are removing old version of the ruby?

rvm install 2.4.2 // version of ruby u need to insatll rvm use 2.4.2 --default // set ruby version you want use by default

Using rvm you can install multiple ruby version in the system

Please follow below steps install ruby using rvm

sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 
curl -sSL https://get.rvm.io | bash -s stable 
source ~/.rvm/scripts/rvm
rvm install 2.4.2 
rvm use 2.4.2 --default 
ruby -v

The installation step will change for different Ubuntu version

If all you want to do is read the same information more than once, and the input data is small enough to fit into memory, you can copy the data from your InputStream to a ByteArrayOutputStream.

Then you can obtain the associated array of bytes and open as many "cloned" ByteArrayInputStreams as you like.

ByteArrayOutputStream baos = new ByteArrayOutputStream();

// Code simulating the copy
// You could alternatively use NIO
// And please, unlike me, do something about the Exceptions :D
byte[] buffer = new byte[1024];
int len;
while ((len = input.read(buffer)) > -1 ) {
    baos.write(buffer, 0, len);
}
baos.flush();
    
// Open new InputStreams using recorded bytes
// Can be repeated as many times as you wish
InputStream is1 = new ByteArrayInputStream(baos.toByteArray()); 
InputStream is2 = new ByteArrayInputStream(baos.toByteArray()); 

But if you really need to keep the original stream open to receive new data, then you will need to track the external call to close(). You will need to prevent close() from being called somehow.

UPDATE (2019):

Since Java 9 the the middle bits can be replaced with InputStream.transferTo:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
input.transferTo(baos);
InputStream firstClone = new ByteArrayInputStream(baos.toByteArray()); 
InputStream secondClone = new ByteArrayInputStream(baos.toByteArray()); 

You can use a lambda:

Collectors.toMap(p -> p.getLast(), Function.identity())

or, more concisely, you can use a method reference using :::

Collectors.toMap(Person::getLast, Function.identity())

and instead of Function.identity, you can simply use the equivalent lambda:

Collectors.toMap(Person::getLast, p -> p)

If you use Netbeans you should get hints whenever an anonymous class can be replaced by a lambda.

Here is a little research that explored RDBMS vs NoSQL using MySQL vs Mongo, the conclusions were inline with @Sean Reilly's response. In short, the benefit comes from the design, not some raw speed difference. Conclusion on page 35-36:

RDBMS vs NoSQL: Performance and Scaling Comparison

The project tested, analysed and compared the performance and scalability of the two database types. The experiments done included running different numbers and types of queries, some more complex than others, in order to analyse how the databases scaled with increased load. The most important factor in this case was the query type used as MongoDB could handle more complex queries faster due mainly to its simpler schema at the sacrifice of data duplication meaning that a NoSQL database may contain large amounts of data duplicates. Although a schema directly migrated from the RDBMS could be used this would eliminate the advantage of MongoDB’s underlying data representation of subdocuments which allowed the use of less queries towards the database as tables were combined. Despite the performance gain which MongoDB had over MySQL in these complex queries, when the benchmark modelled the MySQL query similarly to the MongoDB complex query by using nested SELECTs MySQL performed best although at higher numbers of connections the two behaved similarly. The last type of query benchmarked which was the complex query containing two JOINS and and a subquery showed the advantage MongoDB has over MySQL due to its use of subdocuments. This advantage comes at the cost of data duplication which causes an increase in the database size. If such queries are typical in an application then it is important to consider NoSQL databases as alternatives while taking in account the cost in storage and memory size resulting from the larger database size.

These are the droids you're looking for. This is taken from validator.js which is the library you should really use to do this. But if you want to roll your own, who am I to stop you? If you want pure regex then you can just take out the length check. I think it's a good idea to test the length of the URL though if you really want to determine compliance with the spec.

 function isURL(str) {
     var urlRegex = '^(?!mailto:)(?:(?:http|https|ftp)://)(?:\\S+(?::\\S*)?@)?(?:(?:(?:[1-9]\\d?|1\\d\\d|2[01]\\d|22[0-3])(?:\\.(?:1?\\d{1,2}|2[0-4]\\d|25[0-5])){2}(?:\\.(?:[0-9]\\d?|1\\d\\d|2[0-4]\\d|25[0-4]))|(?:(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)(?:\\.(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)*(?:\\.(?:[a-z\\u00a1-\\uffff]{2,})))|localhost)(?::\\d{2,5})?(?:(/|\\?|#)[^\\s]*)?$';
     var url = new RegExp(urlRegex, 'i');
     return str.length < 2083 && url.test(str);
}

var http = require('http');
var url = process.argv[2];

http.get(url, function(response) {
  var finalData = "";

  response.on("data", function (data) {
    finalData += data.toString();
  });

  response.on("end", function() {
    console.log(finalData.length);
    console.log(finalData.toString());
  });

});

Just do this:

app.use(morgan('tiny'));

and it will work.

Personally:

for _ in range(50):
    print "Some thing"

if you don't need i. If you use Python < 3 and you want to repeat the loop a lot of times, use xrange as there is no need to generate the whole list beforehand.

You could remove the bar with the close icon with the techinques described above and then add a close icon yourself.

CSS:

.CloseButton {
background: url('../icons/close-button.png');   
width:15px;
height:15px;
border: 0px solid white;
top:0;
right:0;
position:absolute;
cursor: pointer;
z-index:999;
}

HTML:

var closeDiv = document.createElement("div");
closeDiv.className = "CloseButton";

//append this div to the div holding your content

JS:

 $(closeDiv).click(function () {
         $("yourDialogContent").dialog('close');
     });

To clear Application Data Please Try this way.

    public void clearApplicationData() {
    File cache = getCacheDir();
    File appDir = new File(cache.getParent());
    if (appDir.exists()) {
        String[] children = appDir.list();
        for (String s : children) {
            if (!s.equals("lib")) {
                deleteDir(new File(appDir, s));Log.i("TAG", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************");
            }
        }
    }
}

public static boolean deleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
    }

    return dir.delete();
}

First you need to compose the message. The bare minimum is composed of these two headers:

MIME-Version: 1.0
Content-Type: text/html

... and the appropriate message body:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head><title></title>
</head>
<body>

<p>Hello, world!</p>

</body>
</html>

Once you have it, you can pass the appropriate information to the mail command:

body = '...'

echo $body | mail \
-a "From: [email protected]" \
-a "MIME-Version: 1.0" \
-a "Content-Type: text/html" \
-s "This is the subject" \
[email protected]

This is an oversimplified example, since you also need to take care of charsets, encodings, maximum line length... But this is basically the idea.

Alternatively, you can write your script in Perl or PHP rather than plain shell.

Update

A shell script is basically a text file with Unix line endings that starts with a line called shebang that tells the shell what interpreter it must pass the file to, follow some commands in the language the interpreter understands and has execution permission (in Unix that's a file attribute). E.g., let's say you save the following as hello-world:

#!/bin/sh

echo Hello, world!

Then you assign execution permission:

chmod +x hello-world

And you can finally run it:

./hello-world

Whatever, this is kind of unrelated to the original question. You should get familiar with basic shell scripting before doing advanced tasks with it. Here you are a couple of links about bash, a popular shell:

http://www.gnu.org/software/bash/manual/html_node/index.html

http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html

The SQL standard way to implement recursive queries, as implemented e.g. by IBM DB2 and SQL Server, is the WITH clause. See this article for one example of translating a CONNECT BY into a WITH (technically a recursive CTE) -- the example is for DB2 but I believe it will work on SQL Server as well.

Edit: apparently the original querant requires a specific example, here's one from the IBM site whose URL I already gave. Given a table:

CREATE TABLE emp(empid  INTEGER NOT NULL PRIMARY KEY,
                 name   VARCHAR(10),
                 salary DECIMAL(9, 2),
                 mgrid  INTEGER);

where mgrid references an employee's manager's empid, the task is, get the names of everybody who reports directly or indirectly to Joan. In Oracle, that's a simple CONNECT:

SELECT name 
  FROM emp
  START WITH name = 'Joan'
  CONNECT BY PRIOR empid = mgrid

In SQL Server, IBM DB2, or PostgreSQL 8.4 (as well as in the SQL standard, for what that's worth;-), the perfectly equivalent solution is instead a recursive query (more complex syntax, but, actually, even more power and flexibility):

WITH n(empid, name) AS 
   (SELECT empid, name 
    FROM emp
    WHERE name = 'Joan'
        UNION ALL
    SELECT nplus1.empid, nplus1.name 
    FROM emp as nplus1, n
    WHERE n.empid = nplus1.mgrid)
SELECT name FROM n

Oracle's START WITH clause becomes the first nested SELECT, the base case of the recursion, to be UNIONed with the recursive part which is just another SELECT.

SQL Server's specific flavor of WITH is of course documented on MSDN, which also gives guidelines and limitations for using this keyword, as well as several examples.

Most of the answers suggest the Array.prototype.indexOf method, the only problem is that it will not work on any IE version before IE9.

As an alternative I leave you two more options that will work on all browsers:

if (/Foo|Bar|Baz/.test(str)) {
  // ...
}


if (str.match("Foo|Bar|Baz")) {
  // ...
}

If you want to add a product into the array you can use:

$item['product'] = $product;

Simple way without methods

int x = 1, y = 2, z = 3;

int biggest = x;
if (y > biggest) {
    biggest = y;
}
if (z > biggest) {
    biggest = z;
}
System.out.println(biggest);
//    System.out.println(Math.max(Math.max(x,y),z));

As this question comes often, here is the simple explanation.

datetime or time module has two important functions.

• strftime - creates a string representation of date or time from a datetime or time object.
• strptime - creates a datetime or time object from a string.

In both cases, we need a formating string. It is the representation that tells how the date or time is formatted in your string.

Now lets assume we have a date object.

>>> from datetime import datetime
>>> d = datetime(2010, 2, 15)
>>> d
datetime.datetime(2010, 2, 15, 0, 0)

If we want to create a string from this date in the format 'Mon Feb 15 2010'

>>> s = d.strftime('%a %b %d %y')
>>> print s
Mon Feb 15 10

Lets assume we want to convert this s again to a datetime object.

>>> new_date = datetime.strptime(s, '%a %b %d %y')
>>> print new_date
2010-02-15 00:00:00

Refer This document all formatting directives regarding datetime.

If You are comparing only with the date vale, then converting it to date (not datetime) will work

select id,numbers_from,created_date,amount_numbers,SMS_text 
 from Test_Table
 where 
 created_date <= convert(date,'2013-04-12',102)

This conversion is also applicable during using GetDate() function

You might need to convert the decimal to money (or decimal(8,2)) to get that exact formatting. The convert method can take a third parameter that controls the formatting style:

convert(varchar, cast(price as money))       12345.67
convert(varchar, cast(price as money), 0)    12345.67
convert(varchar, cast(price as money), 1)    12,345.67

$str = basename($url);

mvn clean install -U

Solved my problem. Since the repos were cached, I needed to force it to get latest version.

I had this problem on OSX Sierra 10.12.2. It turns out I had the wrong version of Python installed (I had Python 3.4 but tensorflow pypi packages for OSX are only for python 3.5 and up).

The solution was to install Python 3.6. Here's what I did to get it working. Note: I used Homebrew to install Python 3.6, you could do the same by using the Python 3.6 installer on python.org

brew uninstall python3
brew install python3
python3 --version # Verify that you see "Python 3.6.0"
pip install tensorflow # With python 3.6 the install succeeds
pip install jupyter # "ipython notebook" didn't work for me until I installed jupyter
ipython notebook # Finally works!

To suppress output, use redirection to NUL.

There are two kinds of output that console commands use:

• standard output, or stdout,

• standard error, or stderr.

Of the two, stdout is used more often, both by internal commands, like copy, and by console utilities, or external commands, like find and others, as well as by third-party console programs.

>NUL suppresses the standard output and works fine e.g. for suppressing the 1 file(s) copied. message of the copy command. An alternative syntax is 1>NUL. So,

COPY file1 file2 >NUL

or

COPY file1 file2 1>NUL

or

>NUL COPY file1 file2

or

1>NUL COPY file1 file2

suppresses all of COPY's standard output.

To suppress error messages, which are typically printed to stderr, use 2>NUL instead. So, to suppress a File Not Found message that DEL prints when, well, the specified file is not found, just add 2>NUL either at the beginning or at the end of the command line:

DEL file 2>NUL

or

2>NUL DEL file

Although sometimes it may be a better idea to actually verify whether the file exists before trying to delete it, like you are doing in your own solution. Note, however, that you don't need to delete the files one by one, using a loop. You can use a single command to delete the lot:

IF EXIST "%scriptDirectory%*.noext" DEL "%scriptDirectory%*.noext"

I wanted to search for the term "Stripe" in all files except those within a plugin ("plugin" folder) or within the files ending in ".bak", ".bak2" or ".log" (this is within the wp-contents folder structure of a wordpress install).

I just wanted to do this search one time and very quickly, so I didn't want to alter the search settings of my environment. Here's how I did it (note the double asteriks for the folder):

• Search Term: Stripe
• Include Files: {blank}
• Exclude Files: *.bak*, *.log, **/plugins/**

Here's what it looked like

For people using private GitLabs, here's a snippet that may help: https://gist.github.com/MicahParks/1ba2b19c39d1e5fccc3e892837b10e21

Also pasted below:

Problem

The go command line tool needs to be able to fetch dependencies from your private GitLab, but authenticaiton is required.

This assumes your private GitLab is hosted at privategitlab.company.com.

Environment variables

The following environment variables are recommended:

export GO111MODULE=on
export GOPRIVATE=privategitlab.company.com

The above lines might fit best in your shell startup, like a ~/.bashrc.

Explanation

GO111MODULE=on tells Golang command line tools you are using modules. I have not tested this with projects not using Golang modules on a private GitLab.

GOPRIVATE=privategitlab.company.com tells Golang command line tools to not use public internet resources for the hostnames listed (like the public module proxy).

Get a personal access token from your private GitLab

To future proof these instructions, please follow this guide from the GitLab docs. I know that the read_api scope is required for Golang command line tools to work, and I may suspect read_repository as well, but have not confirmed this.

Set up the ~/.netrc

In order for the Golang command line tools to authenticate to GitLab, a ~/.netrc file is best to use.

To create the file if it does not exist, run the following commands:

touch ~/.netrc
chmod 600 ~/.netrc

Now edit the contents of the file to match the following:

machine privategitlab.company.com login USERNAME_HERE password TOKEN_HERE

Where USERNAME_HERE is replaced with your GitLab username and TOKEN_HERE is replaced with the access token aquired in the previous section.

Common mistakes

Do not set up a global git configuration with something along the lines of this:

git config --global url."[email protected]:".insteadOf "https://privategitlab.company.com"

I beleive at the time of writing this, the SSH git is not fully supported by Golang command line tools and this may cause conflicts with the ~/.netrc.

Bonus: SSH config file

For regular use of the git tool, not the Golang command line tools, it's convient to have a ~/.ssh/config file set up. In order to do this, run the following commands:

mkdir ~/.ssh
chmod 700 ~/.ssh
touch ~/.ssh/config
chmod 600 ~/.ssh/config

Please note the permissions on the files and directory above are essentail for SSH to work in it's default configuration on most Linux systems.

Then, edit the ~/.ssh/config file to match the following:

Host privategitlab.company.com
  Hostname privategitlab.company.com
  User USERNAME_HERE
  IdentityFile ~/.ssh/id_rsa

Please note the spacing in the above file matters and will invalidate the file if it is incorrect.

Where USERNAME_HERE is your GitLab username and ~/.ssh/id_rsa is the path to your SSH private key in your file system. You've already uploaded its public key to GitLab. Here are some instructions.

Documentation says:

DISTINCT ON ( expression [, ...] ) keeps only the first row of each set of rows where the given expressions evaluate to equal. [...] Note that the "first row" of each set is unpredictable unless ORDER BY is used to ensure that the desired row appears first. [...] The DISTINCT ON expression(s) must match the leftmost ORDER BY expression(s).

Official documentation

So you'll have to add the address_id to the order by.

Alternatively, if you're looking for the full row that contains the most recent purchased product for each address_id and that result sorted by purchased_at then you're trying to solve a greatest N per group problem which can be solved by the following approaches:

The general solution that should work in most DBMSs:

SELECT t1.* FROM purchases t1
JOIN (
    SELECT address_id, max(purchased_at) max_purchased_at
    FROM purchases
    WHERE product_id = 1
    GROUP BY address_id
) t2
ON t1.address_id = t2.address_id AND t1.purchased_at = t2.max_purchased_at
ORDER BY t1.purchased_at DESC

A more PostgreSQL-oriented solution based on @hkf's answer:

SELECT * FROM (
  SELECT DISTINCT ON (address_id) *
  FROM purchases 
  WHERE product_id = 1
  ORDER BY address_id, purchased_at DESC
) t
ORDER BY purchased_at DESC

Problem clarified, extended and solved here: Selecting rows ordered by some column and distinct on another

Tom, believe this will fail when there is more than one value returned in select max([COLUMN_NAME]) from [TABLE_NAME] section. i.e. where there are more than 2 values in the data set.

Slight modification to your query will work -

select max([COLUMN_NAME]) from [TABLE_NAME] where [COLUMN_NAME] **IN** 
  ( select max([COLUMN_NAME]) from [TABLE_NAME] )

open is only for another module for example: cocoa pods, or unit test, we can inherit or override

If double-clicking on it brings up WinRAR, you need to change the program you are running it with. You can right-click on it and click "Open with". Java should be listed in there.

However, you must first upgrade your Java version to be compatible with that JAR.

I assume you are getting an error like.. TypeError: 'PixelAccess' object is not iterable...?

See the Image.load documentation for how to access pixels..

Basically, to get the list of pixels in an image, using PIL:

from PIL import Image
i = Image.open("myfile.png")

pixels = i.load() # this is not a list, nor is it list()'able
width, height = i.size

all_pixels = []
for x in range(width):
    for y in range(height):
        cpixel = pixels[x, y]
        all_pixels.append(cpixel)

That appends every pixel to the all_pixels - if the file is an RGB image (even if it only contains a black-and-white image) these will be a tuple, for example:

(255, 255, 255)

To convert the image to monochrome, you just average the three values - so, the last three lines of code would become..

cpixel = pixels[x, y]
bw_value = int(round(sum(cpixel) / float(len(cpixel))))
# the above could probably be bw_value = sum(cpixel)/len(cpixel)
all_pixels.append(bw_value)

Or to get the luminance (weighted average):

cpixel = pixels[x, y]
luma = (0.3 * cpixel[0]) + (0.59 * cpixel[1]) + (0.11 * cpixel[2])
all_pixels.append(luma)

Or pure 1-bit looking black and white:

cpixel = pixels[x, y]
if round(sum(cpixel)) / float(len(cpixel)) > 127:
    all_pixels.append(255)
else:
    all_pixels.append(0)

There is probably methods within PIL to do such RGB -> BW conversions quicker, but this works, and isn't particularly slow.

If you only want to perform calculations on each row, you could skip adding all the pixels to an intermediate list.. For example, to calculate the average value of each row:

from PIL import Image
i = Image.open("myfile.png")

pixels = i.load() # this is not a list
width, height = i.size
row_averages = []
for y in range(height):
    cur_row_ttl = 0
    for x in range(width):
        cur_pixel = pixels[x, y]
        cur_pixel_mono = sum(cur_pixel) / len(cur_pixel)
        cur_row_ttl += cur_pixel_mono

    cur_row_avg = cur_row_ttl / width
    row_averages.append(cur_row_avg)

print "Brighest row:",
print max(row_averages)

It could be dependent upon what is supported by the module you are trying to compile. If your makefile is generated by using autotools, use:

--prefix=<myinstalldir>

when running the ./configure

some packages allow you to also override when running:

make prefix=<myinstalldir>

however, if your not using ./configure, only way to know for sure is to open up the makefile and check. It should be one of the first few variables at the top.

pandas has vectorized string operations, so you can just filter out the rows that contain the string you don't want:

In [91]: df = pd.DataFrame(dict(A=[5,3,5,6], C=["foo","bar","fooXYZbar", "bat"]))

In [92]: df
Out[92]:
   A          C
0  5        foo
1  3        bar
2  5  fooXYZbar
3  6        bat

In [93]: df[~df.C.str.contains("XYZ")]
Out[93]:
   A    C
0  5  foo
1  3  bar
3  6  bat

I know this is an old question, but we were faced with the same problem when trying to inject Strings. So we invented a JUnit5/Mockito extension that does exactly what you want: https://github.com/exabrial/mockito-object-injection

EDIT:

@InjectionMap
 private Map<String, Object> injectionMap = new HashMap<>();

 @BeforeEach
 public void beforeEach() throws Exception {
  injectionMap.put("securityEnabled", Boolean.TRUE);
 }

 @AfterEach
 public void afterEach() throws Exception {
  injectionMap.clear();
 }

From the respective W3 specifications —which happen to be pretty unclear due to a lack of context— one can deduce the following:

• word-break: break-all is for breaking up foreign, non-CJK (say Western) words in CJK (Chinese, Japanese or Korean) character writings.
• word-wrap: break-word is for word breaking in a non-mixed (let us say solely Western) language.

At least, these were W3's intentions. What actually happened was a major cock-up with browser incompatibilities as a result. Here is an excellent write-up of the various problems involved.

The following code snippet may serve as a summary of how to achieve word wrapping using CSS in a cross browser environment:

-ms-word-break: break-all;
 word-break: break-all;

 /* Non standard for webkit */
 word-break: break-word;

-webkit-hyphens: auto;
   -moz-hyphens: auto;
    -ms-hyphens: auto;
        hyphens: auto;

In the old days, when we could assume that most computers used ASCII, we would just do

int i = c[0] - '0';

But in these days of Unicode, it's not a good idea. It was never a good idea if your code had to run on a non-ASCII computer.

Edit: Although it looks hackish, evidently it is guaranteed by the standard to work. Thanks @Earwicker.

As far as I can tell Sqlite doesn't support INFORMATION_SCHEMA. Instead it has sqlite_master.

I don't think you can get the list you want in just one command. You can get the information you need using sql or pragma, then use regex to split it into the format you need

SELECT sql FROM sqlite_master WHERE name='tablename';

gives you something like

CREATE TABLE tablename(
        col1 INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
        col2 NVARCHAR(100) NOT NULL,
        col3 NVARCHAR(100) NOT NULL,
)

Or using pragma

PRAGMA table_info(tablename);

gives you something like

0|col1|INTEGER|1||1
1|col2|NVARCHAR(100)|1||0
2|col3|NVARCHAR(100)|1||0

The problem is with ssl

you should use sudo. Follow below method to resolve the issue.

if you are getting this issue enter sudo npm config set strict-ssl false password: Enter current username password

then now run all ur command wit sudo sudo npm npm install -g underscore password: Enter current username password

Even after if your getting error. Your proxy will be problem. few corporate proxy will be blocked, so you should use wifi or open network to fix this issue.

javascript:

parseInt('06'); // 6
parseInt('08'); // 0

I had a similar problem and since I couldn't find a sufficient solution, I also created a serialization library for javascript: https://github.com/wavesoft/jbb (as a matter of fact it's a bit more, since it's mainly intended for bundling resources)

It is close to Binary-JSON but it adds a couple of additional features, such as metadata for the objects being encoded and some extra optimizations like data de-duplication, cross-referencing to other bundles and structure-level compression.

However there is a catch: In order to keep the bundle size small there are no type information in the bundle. Such information are provided in a separate "profile" that describes your objects for encoding and decoding. For optimization reasons this information is given in a form of script.

But you can make your life easier using the gulp-jbb-profile (https://github.com/wavesoft/gulp-jbb-profile) utility for generating the encodeing/decoding scripts from simple YAML object specifications like this:

# The 'Person' object has the 'age' and 'isOld'
# properties
Person:
  properties:
    - age
    - isOld

For example you can have a look on the jbb-profile-three profile. When you have your profile ready, you can use JBB like this:

var JBBEncoder = require('jbb/encode');
var MyEncodeProfile = require('profile/profile-encode');

// Create a new bundle
var bundle = new JBBEncoder( 'path/to/bundle.jbb' );

// Add one or more profile(s) in order for JBB
// to understand your custom objects
bundle.addProfile(MyEncodeProfile);

// Encode your object(s) - They can be any valid
// javascript object, or objects described in
// the profiles you added previously.

var p1 = new Person(77);
bundle.encode( p1, 'person' );

var people = [
        new Person(45),
        new Person(77),
        ...
    ];
bundle.encode( people, 'people' );

// Close the bundle when you are done
bundle.close();

And you can read it back like this:

var JBBDecoder = require('jbb/decode');
var MyDecodeProfile = require('profile/profile-decode');

// Instantiate a new binary decoder
var binaryLoader = new JBBDecoder( 'path/to/bundle' );

// Add your decoding profile
binaryLoader.addProfile( MyDecodeProfile );

// Add one or more bundles to load
binaryLoader.add( 'bundle.jbb' );

// Load and callback when ready
binaryLoader.load(function( error, database ) {

    // Your objects are in the database
    // and ready to use!
    var people = database['people'];

});

--EDIT-- It looks like I took his question heading too literally - he was asking for an array of ints rather than a List --EDIT ENDS--

Yet another helper method...

private static int[] StringToIntArray(string myNumbers)
{
    List<int> myIntegers = new List<int>();
    Array.ForEach(myNumbers.Split(",".ToCharArray()), s =>
    {
        int currentInt;
        if (Int32.TryParse(s, out currentInt))
            myIntegers.Add(currentInt);
    });
    return myIntegers.ToArray();
}

quick test code for it, too...

static void Main(string[] args)
{
    string myNumbers = "1,2,3,4,5";
    int[] myArray = StringToIntArray(myNumbers);
    Console.WriteLine(myArray.Sum().ToString()); // sum is 15.

    myNumbers = "1,2,3,4,5,6,bad";
    myArray = StringToIntArray(myNumbers);
    Console.WriteLine(myArray.Sum().ToString()); // sum is 21

    Console.ReadLine();
}

Spaces will not be a problem for cast, however characters like TAB, CR or LF will appear as spaces, will not be trimmed by LTRIM or RTRIM, and will be a problem.

For example try the following:

declare @v1 varchar(21) = '66',
        @v2 varchar(21) = '   66   ',
        @v3 varchar(21) = '66' + char(13) + char(10),
        @v4 varchar(21) = char(9) + '66'

select cast(@v1 as int)   -- ok
select cast(@v2 as int)   -- ok
select cast(@v3 as int)   -- error
select cast(@v4 as int)   -- error

Check your input for these characters and if you find them, use REPLACE to clean up your data.

Per your comment, you can use REPLACE as part of your cast:

select cast(replace(replace(@v3, char(13), ''), char(10), '') as int)

If this is something that will be happening often, it would be better to clean up the data and modify the way the table is populated to remove the CR and LF before it is entered.

I can't repro, but I suspect that in your actual code there is a constraint somewhere that T : class - you need to propagate that to make the compiler happy, for example (hard to say for sure without a repro example):

public class Derived<SomeModel> : Base<SomeModel> where SomeModel : class, IModel
                                                                    ^^^^^
                                                                 see this bit

Use os.rename(src, dst) to rename or move a file or a directory.

$ ls
cheese_cheese_type.bar  cheese_cheese_type.foo
$ python
>>> import os
>>> for filename in os.listdir("."):
...  if filename.startswith("cheese_"):
...    os.rename(filename, filename[7:])
... 
>>> 
$ ls
cheese_type.bar  cheese_type.foo

CAST uses ANSI standard. In case of portability, this will work on other platforms. CONVERT is specific to sql server. But is very strong function. You can specify different styles for dates

  for(var i = 0; i < BoardMessages.length;i++){
        (function(j){
            console.log("Loading message %d".green, j);
            htmlMessageboardString += MessageToHTMLString(BoardMessages[j]);
        })(i);
  }

That should work; however, you should never create a function in a loop. Therefore,

  for(var i = 0; i < BoardMessages.length;i++){
        composeMessage(BoardMessages[i]);
  }

  function composeMessage(message){
      console.log("Loading message %d".green, message);
      htmlMessageboardString += MessageToHTMLString(message);
  }

Type in the command:

netstat -aon | findstr :80

It will show you all processes that use port 80. Notice the pid (process id) in the right column.

If you would like to free the port, go to Task Manager, sort by pid and close those processes.

-a displays all connections and listening ports.

-o displays the owning process ID associated with each connection.

-n displays addresses and port numbers in numerical form.

Another alternative is pushd, which will automatically switch drives as needed. It also allows you to return to the previous directory via popd:

C:\Temp>pushd D:\some\folder

D:\some\folder>popd

C:\Temp>_

In HTML only:

<label>
  <input type="file" name="input-name" style="display: none;" />
  <span>Select file</span>
</label>

Edit: I hadn't tested this in Blink, it actually doesn't work with a <button>, but it should work with most other elements–at least in recent browsers.

Check this fiddle with the code above.

Since the OP asked for the name of the current script file I would prefer

import os
os.path.split(sys.argv[0])[1]

One very important thing is that like other Graph API request, you won't get the JSON data in response, rather the call returns a HTTP REDIRECT to the URL of the profile pic. So, if you want to fetch the URL, you either need to read the response HTTP header or you can use FQLs.

Thanks to https://codepen.io/martinwolf/pen/dyLAC

you can use push method only if the object is an array:

var data = new Array();
data.push({"country": "IN"}).

OR

data['country'] = "IN"

if it's just an object you can use

data.country = "IN";

Here is solution for Hibernate 4.3.7.Final.

pacakge-info.java contains

                typeClass = JavaUtilDateType.class
        )
    })

    }

    @Override
    public Date fromStringValue(String xml) throws HibernateException {

This solution mostly relies on TimestampType implementation with adding additional behaviour through anonymous class of type JdbcTimestampTypeDescriptor.
