As mentioned in Greg's answer, mysqldump db_name | mysql new_db_name is the free, safe, and easy way to transfer data between databases. However, it's also really slow.

If you're looking to backup data, can't afford to lose data (in this or other databases), or are using tables other than innodb, then you should use mysqldump.

If you're looking for something for development, have all of your databases backed up elsewhere, and are comfortable purging and reinstalling mysql (possibly manually) when everything goes wrong, then I might just have the solution for you.

I couldn't find a good alternative, so I built a script to do it myself. I spent a lot of time getting this to work the first time and it honestly terrifies me a little to make changes to it now. Innodb databases were not meant to copied and pasted like this. Small changes cause this to fail in magnificent ways. I haven't had a problem since I finalized the code, but that doesn't mean you won't.

Systems tested on (but may still fail on):

• Ubuntu 16.04, default mysql, innodb, separate files per table
• Ubuntu 18.04, default mysql, innodb, separate files per table

What it does

1. Gets sudo privilege and verifies you have enough storage space to clone the database
2. Gets root mysql privileges
3. Creates a new database named after the current git branch
4. Clones structure to new database
5. Switches into recovery mode for innodb
6. Deletes default data in new database
7. Stops mysql
8. Clones data to new database
9. Starts mysql
10. Links imported data in new database
11. Switches out of recovery mode for innodb
12. Restarts mysql
13. Gives mysql user access to database
14. Cleans up temporary files

How it compares with mysqldump

On a 3gb database, using mysqldump and mysql would take 40-50 minutes on my machine. Using this method, the same process would only take ~8 minutes.

How we use it

We have our SQL changes saved alongside our code and the upgrade process is automated on both production and development, with each set of changes making a backup of the database to restore if there's errors. One problem we ran into was when we were working on a long term project with database changes, and had to switch branches in the middle of it to fix a bug or three.

In the past, we used a single database for all branches, and would have to rebuild the database whenever we switched to a branch that wasn't compatible with the new database changes. And when we switched back, we'd have to run the upgrades again.

We tried mysqldump to duplicate the database for different branches, but the wait time was too long (40-50 minutes), and we couldn't do anything else in the meantime.

This solution shortened the database clone time to 1/5 the time (think coffee and bathroom break instead of a long lunch).

Common tasks and their time

Switching between branches with incompatible database changes takes 50+ minutes on a single database, but no time at all after the initial setup time with mysqldump or this code. This code just happens to be ~5 times faster than mysqldump.

Here are some common tasks and roughly how long they would take with each method:

Create feature branch with database changes and merge immediately:

• Single database: ~5 minutes
• Clone with mysqldump: 50-60 minutes
• Clone with this code: ~18 minutes

Create feature branch with database changes, switch to master for a bugfix, make an edit on the feature branch, and merge:

• Single database: ~60 minutes
• Clone with mysqldump: 50-60 minutes
• Clone with this code: ~18 minutes

Create feature branch with database changes, switch to master for a bugfix 5 times while making edits on the feature branch inbetween, and merge:

• Single database: ~4 hours, 40 minutes
• Clone with mysqldump: 50-60 minutes
• Clone with this code: ~18 minutes

If everything goes smoothly, you should see something like:

You should probably make the Child as functional component if it does not maintain any state and simply renders the props and then call it from the parent. Alternative to this is that you can use hooks with the functional component (useState) which will cause stateless component to re-render.

Also you should not alter the propas as they are immutable. Maintain state of the component.

Child = ({bar}) => (bar);

You have to do a shift and mask (AND) operation. Let b be any byte and p be the index (>= 0) of the bit from which you want to take n bits (>= 1).

First you have to shift right b by p times:

x = b >> p;

Second you have to mask the result with n ones:

mask = (1 << n) - 1;
y = x & mask;

You can put everything in a macro:

#define TAKE_N_BITS_FROM(b, p, n) ((b) >> (p)) & ((1 << (n)) - 1)

In Apache 2.4, there's a new stock module called mod_ratelimit. For emulating modem speeds, you can use mod_dialup. Though I don't see why you just couldn't use mod_ratelimit for everything.

The best solution is <input ... size={input.value.length} />

<android.support.v7.widget.AppCompatButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:backgroundTint="#fff"
    android:textColor="#000"
    android:text="test"/>

Use

xmlns:app="http://schemas.android.com/apk/res-auto"

and the color will acept on pre-lolipop

Beyond what's been said already about selectors, you may want to look at the NSInvocation class.

An NSInvocation is an Objective-C message rendered static, that is, it is an action turned into an object. NSInvocation objects are used to store and forward messages between objects and between applications, primarily by NSTimer objects and the distributed objects system.

An NSInvocation object contains all the elements of an Objective-C message: a target, a selector, arguments, and the return value. Each of these elements can be set directly, and the return value is set automatically when the NSInvocation object is dispatched.

Keep in mind that while it's useful in certain situations, you don't use NSInvocation in a normal day of coding. If you're just trying to get two objects to talk to each other, consider defining an informal or formal delegate protocol, or passing a selector and target object as has already been mentioned.

If you truly want set behavior (I'm going by Java knowledge), then you will be hard pressed to find a solution in JavaScript. Most developers will recommend a unique key to represent each object, but this is unlike set, in that you can get two identical objects each with a unique key. The Java API does the work of checking for duplicate values by comparing hash code values, not keys, and since there is no hash code value representation of objects in JavaScript, it becomes almost impossible to do the same. Even the Prototype JS library admits this shortcoming, when it says:

"Hash can be thought of as an associative array, binding unique keys to values (which are not necessarily unique)..."

http://www.prototypejs.org/api/hash

I got the same error but from a backend job (SSIS job). Upon checking the database's Log file growth setting, the log file was limited growth of 1GB. So what happened is when the job ran and it asked SQL server to allocate more log space, but the growth limit of the log declined caused the job to failed. I modified the log growth and set it to grow by 50MB and Unlimited Growth and the error went away.

In my case I cloned a git-project where both Java and Kotlin included. Then checked another branch and pressed "Sync Project with Gradle Files". Android Studio 3.0.1.

This way works fine for me:

var request = new RestSharp.RestRequest("RESOURCE", RestSharp.Method.POST) { RequestFormat = RestSharp.DataFormat.Json }
                .AddBody(BODY);

var response = Client.Execute(request);

// Handle response errors
HandleResponseErrors(response);

if (Errors.Length == 0)
{ }
else
{ }

Hope this helps! (Although it is a bit late)

you could submit all parameters with such naming:

params[0][topdiameter]
params[0][bottomdiameter]
params[1][topdiameter]
params[1][bottomdiameter]

then later you do something like this:

foreach ($_REQUEST['params'] as $item) {
    echo $item['topdiameter'];
    echo $item['bottomdiameter'];
}

If you don't want to alter the column properties, then you can use the query below.

Since you have a column which has unique IDs (e.g., auto_increment columns), you can use it to remove the duplicates:

DELETE `a`
FROM
    `jobs` AS `a`,
    `jobs` AS `b`
WHERE
    -- IMPORTANT: Ensures one version remains
    -- Change "ID" to your unique column's name
    `a`.`ID` < `b`.`ID`

    -- Any duplicates you want to check for
    AND (`a`.`title` = `b`.`title` OR `a`.`title` IS NULL AND `b`.`title` IS NULL)
    AND (`a`.`company` = `b`.`company` OR `a`.`company` IS NULL AND `b`.`company` IS NULL)
    AND (`a`.`site_id` = `b`.`site_id` OR `a`.`site_id` IS NULL AND `b`.`site_id` IS NULL);

In MySQL, you can simplify it even more with the NULL-safe equal operator (aka "spaceship operator"):

DELETE `a`
FROM
    `jobs` AS `a`,
    `jobs` AS `b`
WHERE
    -- IMPORTANT: Ensures one version remains
    -- Change "ID" to your unique column's name
    `a`.`ID` < `b`.`ID`

    -- Any duplicates you want to check for
    AND `a`.`title` <=> `b`.`title`
    AND `a`.`company` <=> `b`.`company`
    AND `a`.`site_id` <=> `b`.`site_id`;

Replace [ with nothing, then ] with nothing.

How about writing some color-based class in a global sass file, thus we don't need to care where variables are. Just like the following:

// base.scss 
@import "./_variables.scss";

.background-color{
    background: $bg-color;
}

and then, we can use the background-color class in any file. My point is that I don't need to import variable.scss in any file, just use it.

Nick Craver's comment is the simplest to avoid the error that occurs if the dialog has not yet been defined:

if ($('#elem').is(':visible')) { 
  // do something
}

You should set visibility in your CSS first though, using simply:

#elem { display: none; }

count($Contents);

or

sizeof($Contents);

If you don't want to set a background property then you can't set the src attribute of an image using only CSS.

Alternatively you can use JavaScript to do such a thing.

I was able unable to locate the svn.simple file, but was able to change credentials using the following three steps:

Checkout project from SVN

Select the repository you need to change the credentials on (note: you will not perform an checkout, but this will bring you to the screen to enter a username/password combination).

Finally, enter the new username and password credentials:

It's a bit confusing, because you begin the process of initializing a new project, but you're only resetting the repository credentials.

The asker should use STAS answer, but for readers who use prism and no galasoft/mvvmlight, they may want to try what I used:

In the definition at the top for window or usercontrol, etc define namespace:

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

And just below that definition:

<i:Interaction.Triggers>
        <i:EventTrigger EventName="Closing">
            <i:InvokeCommandAction Command="{Binding WindowClosing}" CommandParameter="{Binding}" />
        </i:EventTrigger>
</i:Interaction.Triggers>

Property in your viewmodel:

public ICommand WindowClosing { get; private set; }

Attach delegatecommand in your viewmodel constructor:

this.WindowClosing = new DelegateCommand<object>(this.OnWindowClosing);

Finally, your code you want to reach on close of the control/window/whatever:

private void OnWindowClosing(object obj)
        {
            //put code here
        }

It seems the issue is in "-f ($_.Partition.Size/1GB)}}" If you want the value in MB then change the 1GB to 1MB.

None of the solutions here worked for me out of the box, but it was most likely due my lack of experience with VBA. It might also be because I simply copied and pasted some of the functions above, not knowing details that maybe are necessary to make them work on a VBA for applications environment.

My needs were simply to send xmlhttp requests using urls that contained some special characters of the Norwegian language. Some of the solutions above encode even colons, which made the urls unsuitable for what I needed.

I then decided to write my own URLEncode function. It does not use more clever programming such as the one from @ndd and @Tom. I am not a very experienced programmer, but I had to make this done sooner.

I realized that the problem was that my server didn't accept UTF-16 encodings, so I had to write a function that would convert UTF-16 to UTF-8. A good source of information was found here and here.

I haven't tested it extensively to check if it works with url with characters that have higher unicode values and which would produce more than 2 bytes of utf-8 characters. I am not saying it will decode everything that needs to be decoded (but it is easy to modify to include/exclude characters on the select case statement) nor that it will work with higher characters, as I haven't fully tested. But I am sharing the code because it might help someone who is trying to understand the issue.

Any comments are welcome.

I changed Graphics to Software, Intel x86 Emulator was already installed and also restarted the PC. Nothing worked. It was the Hyper-V issue. I had turned it off for VMWare. I turned it on and restarted the PC and emulator worked. So please try Hyper-V.

For SQL statements you can try reverse snowflakes. You can join at sourceforge or the demo site at http://snowflakejoins.com/.

Perhaps not the best options but just another way is to read the Windows Registry in the host machine, on elevated PowerShell prompt you can do something like this:

#Get SQL instance's Port number using Windows Registry:
$instName = (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server').InstalledInstances[0]
$tcpPort = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\$instName\MSSQLServer\SuperSocketNetLib\Tcp").TcpPort
Write-Host The SQL Instance:  `"$instName`"  is listening on `"$tcpPort`"  "TcpPort."

Ensure to run this PowerShell script in the Host Server (that hosts your SQL instance / SQL Server installation), which means you have to first RDP into the SQL Server/Box/VM, then run this code.

Using .getActivity() solves this issue:

For eg.

Intent i= new Intent(MainActivity.this.getActivity(), Next.class);
startActivity(i);

Hope this helps.

Cheers.

In projects that use the Gradle build system, what you want to change is the applicationId in the build.gradle file. The build system uses this value to override anything specified by hand in the manifest file when it does the manifest merge and build.

For example, your module's build.gradle file looks something like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        // CHANGE THE APPLICATION ID BELOW
        applicationId "com.example.fred.myapplication"
        minSdkVersion 10
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
}

applicationId is the name the build system uses for the property that eventually gets written to the package attribute of the manifest tag in the manifest file. It was renamed to prevent confusion with the Java package name (which you have also tried to modify), which has nothing to do with it.

You can do ../../directory/file.txt - This goes two directories back.

../../../ - this goes three. etc

I think this does the best job

https://angular.io/api/platform-browser/EventManager

for instance in app.component

constructor(private eventManager: EventManager) {
    const removeGlobalEventListener = this.eventManager.addGlobalEventListener(
      'document',
      'keypress',
      (ev) => {
        console.log('ev', ev);
      }
    );
  }

If you define function type first then it would be looked like

type Callback = (n: number) => void;

class Foo {
    save(callback: Callback) : void {        
        callback(42);
    }
}

var foo = new Foo();
var stringCallback = (result: string) : void => {
    console.log(result);
}

var numberCallback = (result: number) : void => {
    console.log(result);
}

foo.save(stringCallback); //--will be showing error
foo.save(numberCallback);

Without function type by using plain property syntax it would be:

class Foo {
    save(callback: (n: number) => void) : void {        
        callback(42);
    }
}

var foo = new Foo();
var stringCallback = (result: string) : void => {
    console.log(result);
}

var numberCallback = (result: number) : void => {
    console.log(result);
}

foo.save(stringCallback); //--will be showing error
foo.save(numberCallback);

If you want by using an interface function like c# generic delegates it would be:

interface CallBackFunc<T, U>
{
    (input:T): U;
};

class Foo {
    save(callback: CallBackFunc<number,void>) : void {        
        callback(42);
    }
}

var foo = new Foo();
var stringCallback = (result: string) : void => {
    console.log(result);
}

var numberCallback = (result: number) : void => {
    console.log(result);
}

let strCBObj:CallBackFunc<string,void> = stringCallback;
let numberCBObj:CallBackFunc<number,void> = numberCallback;

foo.save(strCBObj); //--will be showing error
foo.save(numberCBObj);

Look into twitter cards.

The trick is not in the button but rather the page you are sharing. Twitter Cards pull the image from the meta tags similar to facebook sharing.

Example:

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@site_username">
<meta name="twitter:title" content="Top 10 Things Ever">
<meta name="twitter:description" content="Up than 200 characters.">
<meta name="twitter:creator" content="@creator_username">
<meta name="twitter:image" content="http://placekitten.com/250/250">
<meta name="twitter:domain" content="YourDomain.com">

Seeing as that the original question was on how to use awk and every single one of the first 7 answers use sort instead, and that this is the top hit on Google, here is how to use awk.

Sample net.csv file with headers:

ip,hostname,user,group,encryption,aduser,adattr
192.168.0.1,gw,router,router,-,-,-
192.168.0.2,server,admin,admin,-,-,-
192.168.0.3,ws-03,user,user,-,-,-
192.168.0.4,ws-04,user,user,-,-,-

And sort.awk:

#!/usr/bin/awk -f
# usage: ./sort.awk -v f=FIELD FILE

BEGIN { 
   FS="," 
}

# each line
{ 
   a[NR]=$0 ""
   s[NR]=$f ""  
}

END {
   isort(s,a,NR); 
   for(i=1; i<=NR; i++) print a[i]
}

#insertion sort of A[1..n]
function isort(S, A, n, i, j) {
   for( i=2; i<=n; i++) {
      hs = S[j=i]
      ha = A[j=i]
      while (S[j-1] > hs) { 
         j--; 
         S[j+1] = S[j]
         A[j+1] = A[j] 
      }
      S[j] = hs
      A[j] = ha
   }
}

To use it:

awk sort.awk f=3 < net.csv  # OR 

chmod +x sort.awk
./sort.awk f=3 net.csv

var postData = "text";
      $.ajax({
            type: "post",
            url: "url",
            data: postData,
            contentType: "application/x-www-form-urlencoded",
            success: function(responseData, textStatus, jqXHR) {
                alert("data saved")
            },
            error: function(jqXHR, textStatus, errorThrown) {
                console.log(errorThrown);
            }
        })

I've seen several answers on that, but one remained unclear to me. How would you select those columns of interest?

The answer to that is that if you have them gathered in a list, you can just reference the columns using the list.

Example

print(extracted_features.shape)
print(extracted_features)

(63,)
['f000004' 'f000005' 'f000006' 'f000014' 'f000039' 'f000040' 'f000043'
 'f000047' 'f000048' 'f000049' 'f000050' 'f000051' 'f000052' 'f000053'
 'f000054' 'f000055' 'f000056' 'f000057' 'f000058' 'f000059' 'f000060'
 'f000061' 'f000062' 'f000063' 'f000064' 'f000065' 'f000066' 'f000067'
 'f000068' 'f000069' 'f000070' 'f000071' 'f000072' 'f000073' 'f000074'
 'f000075' 'f000076' 'f000077' 'f000078' 'f000079' 'f000080' 'f000081'
 'f000082' 'f000083' 'f000084' 'f000085' 'f000086' 'f000087' 'f000088'
 'f000089' 'f000090' 'f000091' 'f000092' 'f000093' 'f000094' 'f000095'
 'f000096' 'f000097' 'f000098' 'f000099' 'f000100' 'f000101' 'f000103']

I have the following list/NumPy array extracted_features, specifying 63 columns. The original dataset has 103 columns, and I would like to extract exactly those, then I would use

dataset[extracted_features]

And you will end up with this

This something you would use quite often in machine learning (more specifically, in feature selection). I would like to discuss other ways too, but I think that has already been covered by other Stack Overflower users.

As the whole thing is mixing up let's look at it function and code to simulate what it means consicely

The only way to get a row is via primary key

getRow(pk: PrimaryKey): Row

Primary key data structure can be this:

// If you decide your primary key is just the partition key.
class PrimaryKey(partitionKey: String)

// and in thids case
getRow(somePartitionKey): Row

However you can decide your primary key is partition key + sort key in this case:

// if you decide your primary key is partition key + sort key
class PrimaryKey(partitionKey: String, sortKey: String)

getRow(partitionKey, sortKey): Row
getMultipleRows(partitionKey): Row[]

So the bottom line:

1. Decided that your primary key is partition key only? get single row by partition key.

2. Decided that your primary key is partition key + sort key? 2.1 Get single row by (partition key, sort key) or get range of rows by (partition key)

In either way you get a single row by primary key the only question is if you defined that primary key to be partition key only or partition key + sort key

Building blocks are:

1. Table
2. Item
3. KV Attribute.

Think of Item as a row and of KV Attribute as cells in that row.

1. You can get an item (a row) by primary key.
2. You can get multiple items (multiple rows) by specifying (HashKey, RangeKeyQuery)

You can do (2) only if you decided that your PK is composed of (HashKey, SortKey).

More visually as its complex, the way I see it:

+----------------------------------------------------------------------------------+
|Table                                                                             |

So what is happening above. Notice the following observations. As we said our data belongs to (Table, Item, KVAttribute). Then Every Item has a primary key. Now the way you compose that primary key is meaningful into how you can access the data.

If you decide that your PrimaryKey is simply a hash key then great you can get a single item out of it. If you decide however that your primary key is hashKey + SortKey then you could also do a range query on your primary key because you will get your items by (HashKey + SomeRangeFunction(on range key)). So you can get multiple items with your primary key query.

Note: I did not refer to secondary indexes.

Dave - any luck finding a solution to the browser problem? Is there a way to force a refresh?

As for the original problem, try the following when initializing the form:

def __init__(self, *args, **kwargs):
  super(MyForm, self).__init__(*args, **kwargs)   
  self.base_fields['MyChoiceField'].initial = initial_value

The same issue faced me with XAMPP 7 and opencart Arabic 3. Replacing localhost by the actual machine name reslove the issue.

1. You've got the right idea about how to design your resources, IMHO. I wouldn't change a thing.

2. Rather than trying to extend HTTP with more verbs, consider what your proposed verbs can be reduced to in terms of the basic HTTP methods and resources. For example, instead of an activate_login verb, you could set up resources like: /api/users/1/login/active which is a simple boolean. To activate a login, just PUT a document there that says 'true' or 1 or whatever. To deactivate, PUT a document there that is empty or says 0 or false.

Similarly, to change or set passwords, just do PUTs to /api/users/1/password.

Whenever you need to add something (like a credit) think in terms of POSTs. For example, you could do a POST to a resource like /api/users/1/credits with a body containing the number of credits to add. A PUT on the same resource could be used to overwrite the value rather than add. A POST with a negative number in the body would subtract, and so on.

3. I'd strongly advise against extending the basic HTTP status codes. If you can't find one that matches your situation exactly, pick the closest one and put the error details in the response body. Also, remember that HTTP headers are extensible; your application can define all the custom headers that you like. One application that I worked on, for example, could return a 404 Not Found under multiple circumstances. Rather than making the client parse the response body for the reason, we just added a new header, X-Status-Extended, which contained our proprietary status code extensions. So you might see a response like:

HTTP/1.1 404 Not Found    
X-Status-Extended: 404.3 More Specific Error Here

That way a HTTP client like a web browser will still know what to do with the regular 404 code, and a more sophisticated HTTP client can choose to look at the X-Status-Extended header for more specific information.

4. For authentication, I recommend using HTTP authentication if you can. But IMHO there's nothing wrong with using cookie-based authentication if that's easier for you.

I hope this help.

//Sample of Data Contract:

[DataContract(Name="customer")]
internal class Customer {
  [DataMember(Name="email")] internal string Email { get; set; }
  [DataMember(Name="name")] internal string Name { get; set; }
}

//This is an extension method useful for your case:

public static string JsonSerialize<T>(this T o)
{
  MemoryStream jsonStream = new MemoryStream();
  var serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(typeof(T));
  serializer.WriteObject(jsonStream, o);

  var jsonString = System.Text.Encoding.ASCII.GetString(jsonStream.ToArray());

  var props = o.GetType().GetCustomAttributes(false);
  var rootName = string.Empty;
  foreach (var prop in props)
  {
    if (!(prop is DataContractAttribute)) continue;
    rootName = ((DataContractAttribute)prop).Name;
    break;
  }
  jsonStream.Close();
  jsonStream.Dispose();

  if (!string.IsNullOrEmpty(rootName)) jsonString = string.Format("{{ \"{0}\": {1} }}", rootName, jsonString);

First, find your EditText in the resource of the android studio by using this code:

EditText value = (EditText) findViewById(R.id.editText1);

Then convert EditText value into a string and then parse the value to an int.

int number = Integer.parseInt(x.getText().toString());

This will work

This can be done with PIL. First, install it, then you can take a full screenshot like this:

import PIL.ImageGrab

im = PIL.ImageGrab.grab()
im.show()

One hackish way to define an exit method in context:

class Bar; def exit; end; end 

This works because exit in the initializer will be resolved as self.exit¹. In addition, this approach allows using the object after it has been created, as in: b = B.new.

But really, one shouldn't be doing this: don't have exit (or even puts) there to begin with.

(And why is there an "infinite" loop and/or user input in an intiailizer? This entire problem is primarily the result of poorly structured code.)

¹ Remember Kernel#exit is only a method. Since Kernel is included in every Object, then it's merely the case that exit normally resolves to Object#exit. However, this can be changed by introducing an overridden method as shown - nothing fancy.

Using .replace(/\s+/g,'') works fine;

Example:

this.slug = removeAccent(this.slug).replace(/\s+/g,'');

set multiple css style properties in Javascript

document.getElementById("yourElement").style.cssText = cssString;

or

document.getElementById("yourElement").setAttribute("style",cssString);

Example:

document
.getElementById("demo")
.style
.cssText = "margin-left:100px;background-color:red";

document
.getElementById("demo")

As stated already, running your code through the W3C Validator is great but if your page is complex, you still may not know exactly where to find the open div.

I like using tabs to indent my code. It keeps it visually organized so that these issues are easier to find, children, siblings, parents, etc... they'll appear more obvious.

EDIT: Also, I'll use a few HTML comments to mark closing tags in the complex areas. I keep these to a minimum for neatness.

<body>

    <div>
        Main Content

        <div>
            Div #1 content

            <div>
               Child of div #1

               <div>
                   Child of child of div #1
               </div><!--// close of child of child of div #1 //-->
            </div><!--// close of child of div #1 //-->
        </div><!--// close of div #1 //-->

        <div>
            Div #2 content
        </div>

        <div>

Here is the way works for me.

Declare your ch as

unsigned char ch = 212 ;

And your printf will work.

What you're looking for is

j.d.length

The d is the key. At least it is in my case, I'm using a .NET webservice.

 $.ajax({
            type: "POST",
            url: "CantTellU.asmx",
            data: "{'userID' : " + parseInt($.query.get('ID')) + " }",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function(msg, status) {
                ApplyTemplate(msg);
                alert(msg.d.length);
            }
        });

Under FF you can use the XMLSerializer object to serialize XML into a string. IE gives you an xml property of a node. So you can do the following:

function xml2string(node) {
   if (typeof(XMLSerializer) !== 'undefined') {
      var serializer = new XMLSerializer();
      return serializer.serializeToString(node);
   } else if (node.xml) {
      return node.xml;
   }
}

You can use assertThrows(), But with assertThrows your assertion will pass even if the thrown exception is of child type.

This is because, JUnit 5 checks exception type by calling Class.isIntance(..), Class.isInstance(..) will return true even if the exception thrown is of the child types.

The workaround for this is to assert on Class:

Throwable throwable =  assertThrows(Throwable.class, () -> {
    service.readFile("sampleFile.txt");
});
assertEquals(FileNotFoundException.class, throwable.getClass());

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

Using the index:

df[1:4,]

Where the values in the parentheses can be interpreted as either logical, numeric, or character (matching the respective names):

df[row.index, column.index]

Read help(`[`) for more detail on this subject, and also read about index matrices in the Introduction to R.

**Add Route function to direct the routine what you want**
    public class SomeController : ApiController
    {
        [HttpGet()]
        [Route("GetItems")]
        public SomeValue GetItems(CustomParam parameter) { ... }

        [HttpGet()]
        [Route("GetChildItems")]
        public SomeValue GetChildItems(CustomParam parameter, SomeObject parent) { ... }
    }

The simplest way to do this is to add the .config file in the deployment section on your unit test.

To do so, open the .testrunconfig file from your Solution Items. In the Deployment section, add the output .config files from your project's build directory (presumably bin\Debug).

Anything listed in the deployment section will be copied into the test project's working folder before the tests are run, so your config-dependent code will run fine.

Edit: I forgot to add, this will not work in all situations, so you may need to include a startup script that renames the output .config to match the unit test's name.

If you created a separate module (eg. AppRoutingModule) to contain your routing commands you can get this same error:

Error: StaticInjectorError(AppModule)[RouterLinkWithHref -> Router]: 
StaticInjectorError(Platform: core)[RouterLinkWithHref -> Router]: 
NullInjectorError: No provider for Router!

You may have forgotten to import it to the main AppModule as shown here:

@NgModule({
  imports:      [ BrowserModule, FormsModule, RouterModule, AppRoutingModule ],
  declarations: [ AppComponent, Page1Component, Page2Component ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

integrity - defines the hash value of a resource (like a checksum) that has to be matched to make the browser execute it. The hash ensures that the file was unmodified and contains expected data. This way browser will not load different (e.g. malicious) resources. Imagine a situation in which your JavaScript files were hacked on the CDN, and there was no way of knowing it. The integrity attribute prevents loading content that does not match.

Invalid SRI will be blocked (Chrome developer-tools), regardless of cross-origin. Below NON-CORS case when integrity attribute does not match:

Integrity can be calculated using: https://www.srihash.org/ Or typing into console (link):

openssl dgst -sha384 -binary FILENAME.js | openssl base64 -A

crossorigin - defines options used when the resource is loaded from a server on a different origin. (See CORS (Cross-Origin Resource Sharing) here: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS). It effectively changes HTTP requests sent by the browser. If the “crossorigin” attribute is added - it will result in adding origin: <ORIGIN> key-value pair into HTTP request as shown below.

crossorigin can be set to either “anonymous” or “use-credentials”. Both will result in adding origin: into the request. The latter however will ensure that credentials are checked. No crossorigin attribute in the tag will result in sending a request without origin: key-value pair.

Here is a case when requesting “use-credentials” from CDN:

<script 
        src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js"
        integrity="sha384-vBWWzlZJ8ea9aCX4pEW3rVHjgjt7zpkNpZk+02D9phzyeVkE+jo0ieGizqPLForn" 
        crossorigin="use-credentials"></script>

A browser can cancel the request if crossorigin incorrectly set.

Could the Barcode Rendering Framework at Codeplex GitHub be of help?

I've used DBDesigner before. It is an open source tool. You might check that out. Not sure if it fits your needs.

Best of luck!

In my case, someone had come along and incorrectly edited the redis.conf file to this:

bind 127.0.0.1 ::1
bind 192.168.1.7

when, it really needed to be this (one line):

bind 127.0.0.1 ::1 192.168.1.7

Have you tried adding both to $_SESSION?

Then at the top of your page2.php just add:

<?php
session_start();

TLDR; range is an arithmetic series so it can very easily calculate whether the object is there.It could even get the index of it if it were list like really quickly.

Neovim and Vim 8.2 support this natively via the :ter[minal] command.

See terminal-window in the docs for details.

  $filelist | % {
    $file = $_
    mkdir -force (Split-Path $dest) | Out-Null
    cp $file $dest
  }

A Simpler one by just adjusting lightness/luma/brightness for contrast as is below:

cv2.imshow('test', img)
cv2.waitKey(1000)
imghsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)


imghsv[:,:,2] = [[max(pixel - 25, 0) if pixel < 190 else min(pixel + 25, 255) for pixel in row] for row in imghsv[:,:,2]]
cv2.imshow('contrast', cv2.cvtColor(imghsv, cv2.COLOR_HSV2BGR))
cv2.waitKey(1000)
raw_input()

Just in case anybody has as good a schema to work with as me...
Here is how to do it correctly:

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists (it is very possible it does not have the name you think it has...)
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 
        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';

        -- Check if they keys are unique (it is very possible they might not be)        
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END 

A slightly clumsier but faster approach for larger datasets involves getting the counts for a column of interest, sorting the counts highest to lowest, and then de-duplicating on a subset to only retain the largest cases. The code example is following:

>>> import pandas as pd
>>> source = pd.DataFrame(
        {
            'Country': ['USA', 'USA', 'Russia', 'USA'], 
            'City': ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
            'Short name': ['NY', 'New', 'Spb', 'NY']
        }
    )
>>> grouped_df = source\
        .groupby(['Country','City','Short name'])[['Short name']]\
        .count()\
        .rename(columns={'Short name':'count'})\
        .reset_index()\
        .sort_values('count', ascending=False)\
        .drop_duplicates(subset=['Country', 'City'])\
        .drop('count', axis=1)
>>> print(grouped_df)
  Country              City Short name
1     USA          New-York         NY
0  Russia  Sankt-Petersburg        Spb

For people just stumbling upon this now, I resolved an error of this type that was thrown with all the references and using statements placed properly. There's evidently some confusion with substituting in a function that returns DataTable instead of calling it on a declared DataTable. For example:

This worked for me:

DataTable dt = SomeObject.ReturnsDataTable();

List<string> ls = dt.AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

But this didn't:

List<string> ls = SomeObject.ReturnsDataTable().AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

I'm still not 100% sure why, but if anyone is frustrated by an error of this type, give this a try.

System.Windows.Forms.Application.StartupPath will solve your problem, I think

An interface can extend other interfaces. Also an interface cannot implement any other interface. When it comes to a class, it can extend one other class and implement any number of interfaces.

class A extends B implements C,D{...}

Will this work for you?

div { text-align: center; }

The explanation from Scott Meyers in Effective C++ might help understand when to use them:

Public inheritance should model "is-a relationship," whereas private inheritance should be used for "is-implemented-in-terms-of" - so you don't have to adhere to the interface of the superclass, you're just reusing the implementation.

In my case, Server had lower version framework than your application. installed latest version framework and it fixed this issue.

Set it with a px value. Changing the code like below should work

el.css('marginLeft', mrg + 'px');

In PHP functions will not be evaluated inside strings, because there are different rules for variables.

<?php
function name() {
  return 'Mark';
}

echo 'My name is: name()';   // Output: My name is name()
echo 'My name is: '. name(); // Output: My name is Mark

The action parameter to the tag in HTML should not reference the PHP function you want to run. Action should refer to a page on the web server that will process the form input and return new HTML to the user. This can be the same location as the PHP script that outputs the form, or some people prefer to make a separate PHP file to handle actions.

The basic process is the same either way:

1. Generate HTML form to the user.
2. User fills in the form, clicks submit.
3. The form data is sent to the locations defined by action on the server.
4. The script validates the data and does something with it.
5. Usually a new HTML page is returned.

A simple example would be:

<?php
// $_POST is a magic PHP variable that will always contain
// any form data that was posted to this page.
// We check here to see if the textfield called 'name' had
// some data entered into it, if so we process it, if not we
// output the form.
if (isset($_POST['name'])) {
  print_name($_POST['name']);
}
else {
  print_form();
}

// In this function we print the name the user provided.
function print_name($name) {
  // $name should be validated and checked here depending on use.
  // In this case we just HTML escape it so nothing nasty should
  // be able to get through:
  echo 'Your name is: '. htmlentities($name);
}

// This function is called when no name was sent to us over HTTP.
function print_form() {
  echo '
    <form name="form1" method="post" action="">
    <p><label><input type="text" name="name" id="textfield"></label></p>
    <p><label><input type="submit" name="button" id="button" value="Submit"></label></p>
    </form>
  ';
}
?>

For future information I recommend reading the PHP tutorials: http://php.net/tut.php

There is even a section about Dealing with forms.

Decimal. If you choose double you're leaving yourself open to rounding errors

I ran into this issue because my Main() method wasn't waiting for the task to complete before returning, so the Task<HttpResponseMessage> myTask was being cancelled when my console program exited.

The solution was to call myTask.GetAwaiter().GetResult() in Main() (from this answer).

In macOS / Linux (Ubuntu):

1. To Authenticate you need to add your public part of your SSH key pair to bitbucket from within your user settings: User Settings --> SSH keys

You will find the said public part in your ~/.ssh directory, usually id_rsa.pub . note the .pub part of the file name for Public. it will help you to generate one if you don't already have one

You are not done yet ...

2. You need to let your system know what key to use with which remote host, so add these lines to your ~/.ssh/config file

Host bitbucket.org
 IdentityFile ~/.ssh/PRIVATE_KEY_FILE_NAME

Where PRIVATE_KEY_FILE_NAME is the name of private part of your SSH key pair, if you haven't messed with it, usually its default name is : id_rsa in this case replace PRIVATE_KEY_FILE_NAME above with id_rsa(the private key DOES NOT have a .pub extension)

I had a case where Process.HasExited didn't change after closing the window belonging to the process. So Process.WaitForExit() also didn't work. I had to monitor Process.Responding that went to false after closing the window like that:

while (!_process.HasExited && _process.Responding) {
  Thread.Sleep(100);
}
...

Perhaps this helps someone.

If you don't want any button at all (e.g. you are developing a GUI for blind people where tap cannot be positional and you rely on single/double/long taps):

text.setItemOptions(EditorInfo.IME_ACTION_NONE)

Or in Kotlin:

text.imeOptions = EditorInfo.IME_ACTION_NONE

It moves table down because there is no much space, try to decrease/increase width of certain elements so that it finds some space and does not push the table down. Also you may want to use absolute positioning to position the div at exactly the place you want, for example:

<style>
 #div_id
 {
   position:absolute;
   top:100px; /* set top value */
   left:100px; /* set left value */
   width:100px;  /* set width value */
 }
</style>

If you want to appear it over something, you also need to give it z-index, so it might look like this:

<style>
 #div_id
 {
   position:absolute;
   z-index:999;
   top:100px; /* set top value */
   left:100px; /* set left value */
   width:100px;  /* set width value */
 }
</style>

To add an image to left, right, top or bottom, you can use attributes like this:

android:drawableLeft
android:drawableRight
android:drawableTop
android:drawableBottom

The sample code is given above. You can also achieve this using relative layout.

Just use DROP TABLE IF EXISTS:

DROP TABLE IF EXISTS `foo`;
CREATE TABLE `foo` ( ... );

Try searching the MySQL documentation first if you have any other problems.

Elaborating on the answer provided by Brian R. Bondy: Here's an example that shows why you can't simply size the output buffer to the number of wide characters in the source string:

#include <windows.h>
#include <stdio.h>
#include <wchar.h>
#include <string.h>

/* string consisting of several Asian characters */
wchar_t wcsString[] = L"\u9580\u961c\u9640\u963f\u963b\u9644";

int main() 
{

    size_t wcsChars = wcslen( wcsString);

    size_t sizeRequired = WideCharToMultiByte( 950, 0, wcsString, -1, 
                                               NULL, 0,  NULL, NULL);

    printf( "Wide chars in wcsString: %u\n", wcsChars);
    printf( "Bytes required for CP950 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);

    sizeRequired = WideCharToMultiByte( CP_UTF8, 0, wcsString, -1,
                                        NULL, 0,  NULL, NULL);
    printf( "Bytes required for UTF8 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);
}

And the output:

Wide chars in wcsString: 6
Bytes required for CP950 encoding (excluding NUL terminator): 12
Bytes required for UTF8 encoding (excluding NUL terminator): 18

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

You can do it with:

UPDATE mytable SET Total = Pieces * Price;

You can directly use \\server\share\folder w/ WNetUseConnection, no need to strip it to \\server part only beforehand.

PDFJet offers an open-source version of their library that should be able to handle any basic PDF generation task. It's a purely Java-based solution and it is stated to be compatible with Android. There is a commercial version with some additional features that does not appear to be too expensive.

I like the parts method of Path for this:

grandparent_directory, parent_directory, filename = Path(export_filename).parts[-3:]
log.info(f'{t: <30}: {num_rows: >7} Rows exported to {grandparent_directory}/{parent_directory}/{filename}')

For anyone that is looking for an easy solution in Visual Studio Community 2019, Fine Code Coverage is simple but it works well.

It cannot give accurate numbers on the precise coverage, but it will tell which lines are being covered with green/red gutters.

document.location is a (deprecated but still present) read-only string property, replaced by document.url.

g* does a decent job without ctags being set up.

That is, type g,* (or just * - see below) to search for the word under the cursor (in this case, the function name). Then press n to go to the next (or Shift-n for previous) occurrence.

It doesn't jump directly to the definition, given that this command just searches for the word under the cursor, but if you don't want to deal with setting up ctags at the moment, you can at least save yourself from having to re-type the function name to search for its definition.

--Edit-- Although I've been using g* for a long time, I've recently discovered two shortcuts for these shortcuts!

(a) * will jump to the next occurrence of the word under the cursor. (No need to type the g, the 'goto' command in vi).

(b) # goes to the previous occurrence, in similar fashion.

N and n still work, but '#' is often very useful to start the search initially in the reverse direction, for example, when looking for the declaration of a variable under the cursor.

This is simple code. You can try it and grab the knowledge easily.

n = int(input('Enter integer : '))
    if n % 2 == 3`8huhubuiiujji`:
        print('digit entered is ODD')
    elif n % 2 == 0 and 2 < n < 5:
        print('EVEN AND in between [2,5]')
    elif n % 2 == 0 and 6 < n < 20:
        print('EVEN and in between [6,20]')
    elif n % 2 == 0 and n > 20:
       print('Even and greater than 20')

and so on...

CONIO.H

the functions you need are:

int getch();
Prototype
    int _getch(void); 
Description
    _getch obtains a character  from stdin. Input is unbuffered, and this
    routine  will  return as  soon as  a character is  available  without 
    waiting for a carriage return. The character is not echoed to stdout.
    _getch bypasses the normal buffering done by getchar and getc. ungetc 
    cannot be used with _getch. 
Synonym
    Function: getch 


int kbhit();
Description
    Checks if a keyboard key has been pressed but not yet read. 
Return Value
    Returns a non-zero value if a key was pressed. Otherwise, returns 0.

From bash 4.0 onward, you can use Brace Expansion with fixed length strings. See below for the original announcement.

It will do just what you need, and does not require anything external to the shell.

$ echo {01..05}
01 02 03 04 05

for num in {01..05}
do
  echo $num
done
01
02
03
04
05

CHANGES, release bash-4.0, section 3

This is a terse description of the new features added to bash-4.0 since the release of bash-3.2.

. . .

z. Brace expansion now allows zero-padding of expanded numeric values and will add the proper number of zeroes to make sure all values contain the same number of digits.

@extend .myclass;
@extend #{'.my-class'};

add a condition to check for the admin directory, something like:

RewriteCond %{REQUEST_URI} !^/?(admin|user)/
RewriteRule ^([^/] )/([^/] )\.html$ index.php?lang=$1&mod=$2 [L]

RewriteCond %{REQUEST_URI} !^/?(admin|user)/
RewriteRule ^([^/] )/$ index.php?lang=$1&mod=home [L]

You simply use the destroy() method to delete the specified widgets like this:

lbl = tk.Label(....)

btn = tk.Button(....., command=lambda: lbl.destroy())

Using this you can completely destroy the specific widgets.

You can use lock variables "a" and "b" and synchronize them for locking the "critical section" in reverse order. Eg. Notify "a" then Lock "b" ,"PRINT", Notify "b" then Lock "a".

Please refer the below the code :

public class EvenOdd {

    static int a = 0;

    public static void main(String[] args) {

        EvenOdd eo = new EvenOdd();

        A aobj = eo.new A();
        B bobj = eo.new B();

        aobj.a = Lock.lock1;
        aobj.b = Lock.lock2;

        bobj.a = Lock.lock2;
        bobj.b = Lock.lock1;

        Thread t1 = new Thread(aobj);
        Thread t2 = new Thread(bobj);

        t1.start();
        t2.start();
    }

    static class Lock {
        final static Object lock1 = new Object();
        final static Object lock2 = new Object();
    }

    class A implements Runnable {

        Object a;
        Object b;

        public void run() {
            while (EvenOdd.a < 10) {
                try {
                    System.out.println(++EvenOdd.a + " A ");
                    synchronized (a) {
                        a.notify();
                    }
                    synchronized (b) {
                        b.wait();
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    class B implements Runnable {

        Object a;
        Object b;

        public void run() {
            while (EvenOdd.a < 10) {

                try {
                    synchronized (b) {
                        b.wait();
                        System.out.println(++EvenOdd.a + " B ");
                    }
                    synchronized (a) {
                        a.notify();
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

OUTPUT :

1 A 
2 B 
3 A 
4 B 
5 A 
6 B 
7 A 
8 B 
9 A 
10 B 

To avoid syntax errors, be sure to always put BEGIN and END after an IF clause, eg:

IF (@A!= @SA)
   BEGIN
   --do stuff
   END
IF (@C!= @SC)
   BEGIN
   --do stuff
   END

... and so on. This should work as expected. Imagine BEGIN and END keyword as the opening and closing bracket, respectively.

The PowerShell is almost exactly the same.

$webclient = new-object System.Net.WebClient
$webclient.Credentials = new-object System.Net.NetworkCredential($username, $password, $domain)
$webpage = $webclient.DownloadString($url)

If triangle.lborderA is indeed a long then the test in the original code is trivially true, and there is no way to test it. It is also useless.

However, if triangle.lborderA is a double, the comparison is useful and can be tested. isBiggerThanMaxLong(1e300) does return true.

  public static boolean isBiggerThanMaxLong(double in){
    return in > Long.MAX_VALUE;
  }

For cases where you also wish to have the option of setting 'b' to None:

def p(self, **kwargs):
    b = kwargs.get('b', self.a)
    print b

How to import images into the gallery of an Android Virtual Device using Android Studio: I'm using Android Studio 1.4.1 and a API 15 virtual device.

Warning: This is manual intensive so it is not a good solution for a large number of images.

1. Create a virtual device using Android's Device Manager (AVD), Menu /Tools/Android/AVD Manager.
2. Start this virtual device.
3. Start the Android Device monitor, Menu */Tools/Android/Android Device Monitor. In the Devices tab (upper left) you should see your device. It should be Online (see this screenshot)
4. On the right window is the File Explorer. Go there and select the /mnt/sdcard/Pictures directory. It should be highlighted (see this screenshot)
5. Add jpegs to this directory by clicking on the Push a file onto the device icon (the little phone icon I highlighted in the above screenshot. You can add only one photo at a time, dadburnit.
6. Go to your device and run the Dev Tools app.
7. Scroll down and select Media Provider.
8. Click on the Scan SD Card button. This should copy the images you added in step 5 to the gallery. Go to the gallery and look, they should be there.

Solved this by adding following

RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^ - [L]

It turns out that there is a way to do this, although I'm not sure I've found the 'proper' way since this required hours of reading source code from multiple projects. In other words, this might be a lot of dumb work (but it works).

First, there is no way to get at the server.xml in the embedded Tomcat, either to augment it or replace it. This must be done programmatically.

Second, the 'require_https' setting doesn't help since you can't set cert info that way. It does set up forwarding from http to https, but it doesn't give you a way to make https work so the forwarding isnt helpful. However, use it with the stuff below, which does make https work.

To begin, you need to provide an EmbeddedServletContainerFactory as explained in the Embedded Servlet Container Support docs. The docs are for Java but the Groovy would look pretty much the same. Note that I haven't been able to get it to recognize the @Value annotation used in their example but its not needed. For groovy, simply put this in a new .groovy file and include that file on the command line when you launch spring boot.

Now, the instructions say that you can customize the TomcatEmbeddedServletContainerFactory class that you created in that code so that you can alter web.xml behavior, and this is true, but for our purposes its important to know that you can also use it to tailor server.xml behavior. Indeed, reading the source for the class and comparing it with the Embedded Tomcat docs, you see that this is the only place to do that. The interesting function is TomcatEmbeddedServletContainerFactory.addConnectorCustomizers(), which may not look like much from the Javadocs but actually gives you the Embedded Tomcat object to customize yourself. Simply pass your own implementation of TomcatConnectorCustomizer and set the things you want on the given Connector in the void customize(Connector con) function. Now, there are about a billion things you can do with the Connector and I couldn't find useful docs for it but the createConnector() function in this this guys personal Spring-embedded-Tomcat project is a very practical guide. My implementation ended up looking like this:

package com.deepdownstudios.server

import org.springframework.boot.context.embedded.tomcat.TomcatConnectorCustomizer
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory
import org.apache.catalina.connector.Connector;
import org.apache.coyote.http11.Http11NioProtocol;
import org.springframework.boot.*
import org.springframework.stereotype.*

@Configuration
class MyConfiguration {

@Bean
public EmbeddedServletContainerFactory servletContainer() {
final int port = 8443;
final String keystoreFile = "/path/to/keystore"
final String keystorePass = "keystore-password"
final String keystoreType = "pkcs12"
final String keystoreProvider = "SunJSSE"
final String keystoreAlias = "tomcat"

TomcatEmbeddedServletContainerFactory factory = 
        new TomcatEmbeddedServletContainerFactory(this.port);
factory.addConnectorCustomizers( new TomcatConnectorCustomizer() {
    void    customize(Connector con) {
        Http11NioProtocol proto = (Http11NioProtocol) con.getProtocolHandler();
            proto.setSSLEnabled(true);
        con.setScheme("https");
        con.setSecure(true);
        proto.setKeystoreFile(keystoreFile);
        proto.setKeystorePass(keystorePass);
        proto.setKeystoreType(keystoreType);
        proto.setProperty("keystoreProvider", keystoreProvider);
        proto.setKeyAlias(keystoreAlias);
    }
});
return factory;
}
}

The Autowiring will pick up this implementation an run with it. Once I fixed my busted keystore file (make sure you call keytool with -storetype pkcs12, not -storepass pkcs12 as reported elsewhere), this worked. Also, it would be far better to provide the parameters (port, password, etc) as configuration settings for testing and such... I'm sure its possible if you can get the @Value annotation to work with Groovy.

This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.

This can happen if the other side crashes and then comes back up or if it calls close() on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.

It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.

If you type "AAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGG" this will produce:

AARRRRRRRRRRRRRRRRRRRR
RRGGGGGGGGGGGGGGGGGGGG
G

I have taken my example from a couple different websites on google. I have tested this on ff 5.0, IE 8.0, and Chrome 10. It works on all of them.

.wrapword {
    white-space: -moz-pre-wrap !important;  /* Mozilla, since 1999 */
    white-space: -pre-wrap;      /* Opera 4-6 */
    white-space: -o-pre-wrap;    /* Opera 7 */
    white-space: pre-wrap;       /* css-3 */
    word-wrap: break-word;       /* Internet Explorer 5.5+ */
    white-space: -webkit-pre-wrap; /* Newer versions of Chrome/Safari*/
    word-break: break-all;
    white-space: normal;
}

<table style="table-layout:fixed; width:400px">
    <tr>
        <td class="wrapword"></td>
    </tr>
</table>

You can easily create your own extension method on IEnumerable or IQueryable:

public static IOrderedEnumerable<TSource> OrderByWithDirection<TSource,TKey>
    (this IEnumerable<TSource> source,
     Func<TSource, TKey> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

public static IOrderedQueryable<TSource> OrderByWithDirection<TSource,TKey>
    (this IQueryable<TSource> source,
     Expression<Func<TSource, TKey>> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

Yes, you lose the ability to use a query expression here - but frankly I don't think you're actually benefiting from a query expression anyway in this case. Query expressions are great for complex things, but if you're only doing a single operation it's simpler to just put that one operation:

var query = dataList.OrderByWithDirection(x => x.Property, direction);

if someone needs for interest calculation year in float format

function floatYearDiff(olddate, newdate) {
  var new_y = newdate.getFullYear();
  var old_y = olddate.getFullYear();
  var diff_y = new_y - old_y;
  var start_year = new Date(olddate);
  var end_year = new Date(olddate);
  start_year.setFullYear(new_y);
  end_year.setFullYear(new_y+1);
  if (start_year > newdate) {
    start_year.setFullYear(new_y-1);
    end_year.setFullYear(new_y);
    diff_y--;
  }
  var diff = diff_y + (newdate - start_year)/(end_year - start_year);
  return diff;
}

Okay so someone is probably going to slap me for this answer, but I use jQuery to solve all my irritating problems and it turns out that I just used something today to fix a similar issue. Assuming you use jquery:

$("#content").sibling("#backgroundContainer").css("height",$("#content").outerHeight());

this is untested but I think you can see the concept here. Basically after it is loaded, you can get the height (outerHeight includes padding + borders, innerHeight for the content only). Hope that helps.

Here is how you bind it to the window resize event:

$(window).resize(function() {
  $("#content").sibling("#backgroundContainer").css("height",$("#content").outerHeight());
});

To answer your question, and get the Prefix too, for MySQL you can do:

select Prefix, CR, length(CR) from table1 order by length(CR) DESC limit 1;

and it will return

+-------+----------------------------+--------------------+
| Prefix| CR                         |         length(CR) |
+-------+----------------------------+--------------------+
| g     | ;#WR_1;#WR_2;#WR_3;#WR_4;# |                 26 |
+-------+----------------------------+--------------------+
1 row in set (0.01 sec)

One more option seems to be pyqtdeploy which citing the docs is:

a tool that, in conjunction with other tools provided with Qt, enables the deployment of PyQt4 and PyQt5 applications written with Python v2.7 or Python v3.3 or later. It supports deployment to desktop platforms (Linux, Windows and OS X) and to mobile platforms (iOS and Android).

According to Deploying PyQt5 application to Android via pyqtdeploy and Qt5 it is actively developed, although it is difficult to find examples of working Android apps or tutorial on how to cross-compile all the required libraries to Android. It is an interesting project to keep in mind though!

Even, I was looking for the same regex but I wanted to include the all special character and blank spaces too. So here is the regex for that:

^[A-Za-z0-9\s$&+,:;=?@#|'<>.^*()%!-]{0,10}$

You might need to run it via cmd, eg:

system("cmd /c C:[path to file]");

My suggestion:

using System.Linq;

string myStringOutput = String.Join(",", myArray.Select(p => p.ToString()).ToArray());

Working example

One of the most beautiful ways in my opinion (since it is now commonly available) is using behaviours.

It requires:

• nuget dependency: Microsoft.Xaml.Behaviors.Wpf
• if you already have behaviours built in you might have to follow this guide on Microsofts blog.

xaml code:

xmlns:Interactions="http://schemas.microsoft.com/xaml/behaviors"

AND

<Hyperlink NavigateUri="{Binding Path=Link}">
    <Interactions:Interaction.Behaviors>
        <behaviours:HyperlinkOpenBehaviour ConfirmNavigation="True"/>
    </Interactions:Interaction.Behaviors>
    <Hyperlink.Inlines>
        <Run Text="{Binding Path=Link}"/>
    </Hyperlink.Inlines>
</Hyperlink>

behaviour code:

using System.Windows;
using System.Windows.Documents;
using System.Windows.Navigation;
using Microsoft.Xaml.Behaviors;

namespace YourNameSpace
{
    public class HyperlinkOpenBehaviour : Behavior<Hyperlink>
    {
        public static readonly DependencyProperty ConfirmNavigationProperty = DependencyProperty.Register(
            nameof(ConfirmNavigation), typeof(bool), typeof(HyperlinkOpenBehaviour), new PropertyMetadata(default(bool)));

        public bool ConfirmNavigation
        {
            get { return (bool) GetValue(ConfirmNavigationProperty); }
            set { SetValue(ConfirmNavigationProperty, value); }
        }

        /// <inheritdoc />
        protected override void OnAttached()
        {
            this.AssociatedObject.RequestNavigate += NavigationRequested;
            this.AssociatedObject.Unloaded += AssociatedObjectOnUnloaded;
            base.OnAttached();
        }

        private void AssociatedObjectOnUnloaded(object sender, RoutedEventArgs e)
        {
            this.AssociatedObject.Unloaded -= AssociatedObjectOnUnloaded;
            this.AssociatedObject.RequestNavigate -= NavigationRequested;
        }

        private void NavigationRequested(object sender, RequestNavigateEventArgs e)
        {
            if (!ConfirmNavigation || MessageBox.Show("Are you sure?", "Question", MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes)
            {
                OpenUrl();
            }

            e.Handled = true;
        }

        private void OpenUrl()
        {
//          Process.Start(new ProcessStartInfo(AssociatedObject.NavigateUri.AbsoluteUri));
            MessageBox.Show($"Opening {AssociatedObject.NavigateUri}");
        }

        /// <inheritdoc />
        protected override void OnDetaching()
        {
            this.AssociatedObject.RequestNavigate -= NavigationRequested;
            base.OnDetaching();
        }
    }
}

Use this One

 ((Excel.Range)oSheet.Cells[1, 1]).EntireColumn.ColumnWidth = 10;

First of all, you would have to allocate memory:

char * S = new char[R.length() + 1];

then you can use strcpy with S and R.c_str():

std::strcpy(S,R.c_str());

You can also use R.c_str() if the string doesn't get changed or the c string is only used once. However, if S is going to be modified, you should copy the string, as writing to R.c_str() results in undefined behavior.

Note: Instead of strcpy you can also use str::copy.

Why don't you just use the array of chars you have? This ought to do it:

   source[i] = getc(fp); 
   i++;

=ADDRESS(ROW(),COLUMN())
=ADDRESS(ROW(),COLUMN(),1)
=ADDRESS(ROW(),COLUMN(),2)
=ADDRESS(ROW(),COLUMN(),3)
=ADDRESS(ROW(),COLUMN(),4)

A loose analogy is, "Meteor is to Node as Rails is to Ruby." It's a large, opinionated framework that uses Node on the server. Node itself is just a low-level framework providing functions for sending and receiving HTTP requests and performing other I/O.

Meteor is radically ambitious: By default, every page it serves is actually a Handlebars template that's kept in sync with the server. Try the Leaderboard example: You create a template that simply says "List the names and scores," and every time any client changes a name or score, the page updates with the new data—not just for that client, but for everyone viewing the page.

Another difference: While Node itself is stable and widely used in production, Meteor is in a "preview" state. There are serious bugs, and certain things that don't fit with Meteor's data-centric conceptual model (such as animations) are very hard to do.

If you love playing with new technologies, give Meteor a spin. If you want a more traditional, stable web framework built on Node, take a look at Express.

I wrote a package named Pretty Slice. You can use it to visualize slices, and their backing arrays, etc.

package main

import pretty "github.com/inancgumus/prettyslice"

func main() {
    nums := []int{1, 9, 5, 6, 4, 8}
    odds := nums[:3]
    evens := nums[3:]

    nums[1], nums[3] = 9, 6
    pretty.Show("nums", nums)
    pretty.Show("odds : nums[:3]", odds)
    pretty.Show("evens: nums[3:]", evens)
}

This code is going produce and output like this one:

Please make sure you are using latest jdbc connector as per the mysql. I was facing this problem and when I replaced my old jdbc connector with the latest one, the problem was solved.

You can download latest jdbc driver from https://dev.mysql.com/downloads/connector/j/

Select Operating System as Platform Independent. It will show you two options. One as tar and one as zip. Download the zip and extract it to get the jar file and replace it with your old connector.

This is not only for hibernate framework, it can be used with any platform which requires a jdbc connector.

A couple of additional points re use of vector here.

Unlike ArrayList and Array in Java, you don't need to do anything special to treat a vector as an array - the underlying storage in C++ is guaranteed to be contiguous and efficiently indexable.

Unlike ArrayList, a vector can efficiently hold primitive types without encapsulation as a full-fledged object.

When removing items from a vector, be aware that the items above the removed item have to be moved down to preserve contiguous storage. This can get expensive for large containers.

Make sure if you store complex objects in the vector that their copy constructor and assignment operators are efficient. Under the covers, C++ STL uses these during container housekeeping.

Advice about reserve()ing storage upfront (ie. at vector construction or initialilzation time) to minimize memory reallocation on later extension carries over from Java to C++.

As promised, I'm putting an example for how to use annotations to serialize/deserialize polymorphic objects, I based this example in the Animal class from the tutorial you were reading.

First of all your Animal class with the Json Annotations for the subclasses.

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY)
@JsonSubTypes({
    @JsonSubTypes.Type(value = Dog.class, name = "Dog"),

    @JsonSubTypes.Type(value = Cat.class, name = "Cat") }
)
public abstract class Animal {

    private String name;

    public String getName() {
        return name;
    }

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

}

Then your subclasses, Dog and Cat.

public class Dog extends Animal {

    private String breed;

    public Dog() {

    }

    public Dog(String name, String breed) {
        setName(name);
        setBreed(breed);
    }

    public String getBreed() {
        return breed;
    }

    public void setBreed(String breed) {
        this.breed = breed;
    }
}

public class Cat extends Animal {

    public String getFavoriteToy() {
        return favoriteToy;
    }

    public Cat() {}

    public Cat(String name, String favoriteToy) {
        setName(name);
        setFavoriteToy(favoriteToy);
    }

    public void setFavoriteToy(String favoriteToy) {
        this.favoriteToy = favoriteToy;
    }

    private String favoriteToy;

}

As you can see, there is nothing special for Cat and Dog, the only one that know about them is the abstract class Animal, so when deserializing, you'll target to Animal and the ObjectMapper will return the actual instance as you can see in the following test:

public class Test {

    public static void main(String[] args) {

        ObjectMapper objectMapper = new ObjectMapper();

        Animal myDog = new Dog("ruffus","english shepherd");

        Animal myCat = new Cat("goya", "mice");

        try {
            String dogJson = objectMapper.writeValueAsString(myDog);

            System.out.println(dogJson);

            Animal deserializedDog = objectMapper.readValue(dogJson, Animal.class);

            System.out.println("Deserialized dogJson Class: " + deserializedDog.getClass().getSimpleName());

            String catJson = objectMapper.writeValueAsString(myCat);

            Animal deseriliazedCat = objectMapper.readValue(catJson, Animal.class);

            System.out.println("Deserialized catJson Class: " + deseriliazedCat.getClass().getSimpleName());



        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

Output after running the Test class:

{"@type":"Dog","name":"ruffus","breed":"english shepherd"}

Deserialized dogJson Class: Dog

{"@type":"Cat","name":"goya","favoriteToy":"mice"}

Deserialized catJson Class: Cat

Hope this helps,

You also need to put the [== 'add'] math operation into quotes

if($_POST['group1'] == 'add') {
echo $first + $second;
}

complete code schould look like that :

<?php
$first = $_POST['first'];
$second= $_POST['second'];
if($_POST['group1'] == 'add') {
echo $first + $second;
}
else if($_POST['group1'] == 'subtract') {
echo $first - $second;
}
else if($_POST['group1'] == 'times') {
echo $first * $second;
} 
else if($_POST['group1'] == 'divide') {
echo $first / $second;
}
?>

<CURSOR>Evaluator<T>():
    _bestPos(){

NOW, in NORMAL MODE do

Actually, the absolutely easiest way is to do the following...

byte[] content = your_byte[];

FileContentResult result = new FileContentResult(content, "application/octet-stream") 
{
  FileDownloadName = "your_file_name"
};

return result;

Here is an unbiased version that generates numbers in [low, high]:

int r;
do {
  r = rand();
} while (r < ((unsigned int)(RAND_MAX) + 1) % (high + 1 - low));
return r % (high + 1 - low) + low;

If your range is reasonably small, there is no reason to cache the right-hand side of the comparison in the do loop.

The specificity is calculated based on the amount of id, class and tag selectors in your rule. Id has the highest specificity, then class, then tag. Your first rule is now more specific than the second one, since they both have a class selector, but the first one also has two tag selectors.

To make the second one override the first one, you can make more specific by adding information of it's parents:

table.rule1 tr td.rule2 {
    background-color: #ffff00;
}

Here is a nice article for more information on selector precedence.

I fix the response, and works include all rows (based on response of Pavle Lekic)

Using Advanced Search on Github seemed the easiest with a combination of other answers. It's basically a search string builder. https://github.com/search/advanced

For example I wanted to find all commits in Autodesk/maya-usd containing "USD"

Then in the search results can choose Commits from the list on the left:

select * from information_schema.REFERENTIAL_CONSTRAINTS where 
UNIQUE_CONSTRAINT_SCHEMA = 'TABLE_NAME' 

This will list the column with TABLE_NAME and REFERENCED_COLUMN_NAME.

You could use the LINQ select clause and reference the property that relates to your Name column.

Note: To avoid conflicts between parallel Python 2 and Python 3 installations, only the versioned pip3 and pip3.4 commands are bootstrapped by default when ensurepip is invoked directly - the --default-pip option is needed to also request the unversioned pip command. pyvenv and the Windows installer ensure that the unqualified pip command is made available in those environments, and pip can always be invoked via the -m switch rather than directly to avoid ambiguity on systems with multiple Python installations.

So try pip3 or pip3.4 in Command Prompt.

Also, ensure that environment variable are set for pip command, if you missed to opt-in for automatic PATH configuration.

There's no casting in javascript, so you cannot throw if "casting fails".
Typescript supports casting but that's only for compilation time, and you can do it like this:

const toDo = <IToDoDto> req.body;
// or
const toDo = req.body as IToDoDto;

You can check at runtime if the value is valid and if not throw an error, i.e.:

function isToDoDto(obj: any): obj is IToDoDto {
    return typeof obj.description === "string" && typeof obj.status === "boolean";
}

@Post()
addToDo(@Response() res, @Request() req) {
    if (!isToDoDto(req.body)) {
        throw new Error("invalid request");
    }

    const toDo = req.body as IToDoDto;
    this.toDoService.addToDo(toDo);
    return res.status(HttpStatus.CREATED).end();
}

Edit

As @huyz pointed out, there's no need for the type assertion because isToDoDto is a type guard, so this should be enough:

if (!isToDoDto(req.body)) {
    throw new Error("invalid request");
}

this.toDoService.addToDo(req.body);

Try each_with_index.

So it turns out that if I add the Handler Mappings on the Website and Application level, everything works beautifully. I was only adding them on the server level, thus IIS did not know to map the asp pages to the IsapiModule.

So to resolve this issue, go to the website you want to add your application to, then double click on Handler Mappings. Click "Add Script Map" and enter in the following information:

RequestPath: *.asp
Executable: C:\Windows\System32\inetsrv\asp.dll
Name: Classic ASP (this can be anything you want it to be

If you want to see only fatal runtime errors:

php_value display_errors on
php_value error_reporting 4

For only one line, you need

...
<View android:id="@+id/primerdivisor"
android:layout_height="2dp"
android:layout_width="fill_parent"
android:background="#ffffff" /> 
...

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

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

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

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

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

Finally I solve the issues using below code. This type of error will happen when there is a mismatch between In/Out parameter as declare in procedure and in java code declareParameters. Here we need to defined oracle return tab

public class ManualSaleStoredProcedureDao {

private SimpleJdbcCall getAllSytemUsers;

public List<SystemUser> getAllSytemUsers(String clientCode) {

    MapSqlParameterSource in = new MapSqlParameterSource();
    in.addValue("pi_client_code", clientCode);
    Map<String, Object> result = getAllSytemUsers.execute(in);
    @SuppressWarnings("unchecked")
    List<SystemUser> systemUsers = (List<SystemUser>) result
            .get(VSCConstants.GET_SYSTEM_USER_OUT_PARAM1);
    return systemUsers;

}

public void setDataSource(DataSource dataSource) {

    getAllSytemUsers = new SimpleJdbcCall(dataSource)
            .withSchemaName(VSCConstants.SCHEMA)
            .withProcedureName(VSCConstants.GET_SYSTEM_USER_PROC_NAME)
            .declareParameters(
                    new SqlParameter(
                            "pi_client_code",
                            OracleTypes.NUMBER,
                            "pi_client_code"),
                    new SqlInOutParameter(
                            "po_system_users",
                            OracleTypes.ARRAY,
                            "T_SYSTEM_USER_TAB",
                            new OracleSystemUser()));

}

Another possibility is to use a pseudo selector :after or :before

tr.highlight td:last-child:after
{
  content: "\0a0";
  line-height: 3em;
}

That might avoid issues with browser that don't understand the pseudo selectors, plus background-colors are not an issue.

The downside is however, that it adds some extra whitespace after the last cell.

As far as the http verb is concerned the WebRequest might be easier. You could go for something like:

    WebRequest r = WebRequest.Create("http://some.url");
    r.Method = "POST";
    using (var s = r.GetResponse().GetResponseStream())
    {
        using (var reader = new StreamReader(r, FileMode.Open))
        {
            var content = reader.ReadToEnd();
        }
    }

Obviously this lacks exception handling and writing the request body (for which you can use r.GetRequestStream() and write it like a regular stream, but I hope it may be of some help.

For this error was like others said a big image(1800px X 900px) which was in drawable directory, I edited the image and reduced the size proportionally using photoshop and it worked...!!

Use this,

function restrict(elem){
  var tf = _(elem);
  var rx = new RegExp;
  if(elem == "email"){
       rx = /[ '"]/gi;
  }else if(elem == "search" || elem == "comment"){
    rx = /[^a-z 0-9.,?]/gi;
  }else{
      rx =  /[^a-z0-9]/gi;
  }
  tf.value = tf.value.replace(rx , "" );
}

On the backend, for java , Try using StringUtils class or a custom script.

public static String HTMLEncode(String aTagFragment) {
        final StringBuffer result = new StringBuffer();
        final StringCharacterIterator iterator = new
                StringCharacterIterator(aTagFragment);
        char character = iterator.current();
        while (character != StringCharacterIterator.DONE )
        {
            if (character == '<')
                result.append("&lt;");
            else if (character == '>')
                result.append("&gt;");
            else if (character == '\"')
                result.append("&quot;");
            else if (character == '\'')
                result.append("&#039;");
            else if (character == '\\')
                result.append("&#092;");
            else if (character == '&')
                result.append("&amp;");
            else {
            //the char is not a special one
            //add it to the result as is
                result.append(character);
            }
            character = iterator.next();
        }
        return result.toString();
    }

I had similar issue and just wanted to post an answer for others in my situation.

I have a solution running a ASP.NET Web Application with multiple other C# class lib projects.

My ASP.NET Web Application wasn't using json, but other projects where.

This is how I fixed it:

1. I made sure all projects where using latest version (6) using NuGet Update on all projects currently using any version of json - this didn't fix the issue
2. I added json to the web application using NuGet - this fixed the issue (let me dive into why):

Step 2 was first of all adding a configuration information for json, that suggest that all projects, use the latest version (6) no matter what version they have. Adding the assembly binding to Web.Config is most likely the fix.

However, step 2 also cleaned up som legacy code. It turned out we have previously used an old version (5) of json in our Web Application and the NuGet folders wasn't deleted when the reference was (I suspect: manually) removed. Adding the latest json (6), removed the old folders (json v5). This might be part of the fix as well.

To find the point where to add the -lm in Eclipse-IDE is really horrible, so it took me some time.

If someone else also uses Edlipse, here's the way how to add the command:

Project -> Properties -> C/C++ Build -> Settings -> GCC C Linker -> Miscelleaneous -> Linker flags: in this field add the command -lm

record = int(input("Enter the student record need to add :"))

stud_data={}

for i in range(0,record):
    Name = input("Enter the student name :").split()
    Age = input("Enter the {} age :".format(Name))
    Grade = input("Enter the {} grade :".format(Name)).split()
    Nam_key =  Name[0]
    Age_value = Age[0]
    Grade_value = Grade[0]
    stud_data[Nam_key] = {Age_value,Grade_value}

print(stud_data)

You could also use innerhtml to get the value within the tag....

It was fixed when I removed settings.xml from .m2 folder.

There are some excellent points here and I'm going to add another one in case someones' path crosses here.

Thrift gives you an option to choose between thrift-binary and thrift-compact (de)serializer, thrift-binary will have an excellent performance but bigger packet size, while thrift-compact will give you good compression but needs more processing power. This is handy because you can always switch between these two modes as easily as changing a line of code (heck, even make it configurable). So if you are not sure how much your application should be optimized for packet size or in processing power, thrift can be an interesting choice.

PS: See this excellent benchmark project by thekvs which compares many serializers including thrift-binary, thrift-compact, and protobuf: https://github.com/thekvs/cpp-serializers

PS: There is another serializer named YAS which gives this option too but it is schema-less see the link above.

__init__ is required to return None. You cannot (or at least shouldn't) return something else.

Try making whatever you want to return an instance variable (or function).

>>> class Foo:
...     def __init__(self):
...         return 42
... 
>>> foo = Foo()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __init__() should return None

You can also create a new document from MongoDB compass or using command and set the specific _id value that you want.

For a file:

if exist yourfilename (
  echo Yes 
) else (
  echo No
)

Replace yourfilename with the name of your file.

For a directory:

if exist yourfoldername\ (
  echo Yes 
) else (
  echo No
)

Replace yourfoldername with the name of your folder.

A trailing backslash (\) seems to be enough to distinguish between directories and ordinary files.

I like this:

if (wlocation !== undefined)

But if you prefer the second way wouldn't be as you posted. It would be:

if (typeof wlocation  !== "undefined")

You can use file redirection to redirected the sorted output:

sort input-file > output_file

Or you can use the -o, --output=FILE option of sort to indicate the same input and output file:

sort -o file file

Without repeating the filename (with bash brace expansion)

sort -o file{,}

?? Note: A common mistake is to try to redirect the output to the same input file (e.g. sort file > file). This does not work as the shell is making the redirections (not the sort(1) program) and the input file (as being the output also) will be erased just before giving the sort(1) program the opportunity of reading it.

Answer is simple:

<body oncontextmenu="return false"/> - disable right-click <body ondragstart="return false"/> - disable mouse dragging <body ondrop="return false"/> - disable mouse drop

Hercules is fantastic. It's a fully functioning tcp/udp client/server, amazing for debugging sockets. More details on the web site.

Think about it as array of array.

If you do this str[x][y], then there is array of length x where each element in turn contains array of length y. In java its not necessary for second dimension to have same length. So for x=i you can have y=m and x=j you can have y=n

For this your declaration looks like

String[][] test = new String[4][]; test[0] = new String[3]; test[1] = new String[2];

etc..

Here's another solution not using date(). not so smart:)

$var = '20/04/2012';
echo implode("-", array_reverse(explode("/", $var)));

It can also be done in some other manner

byte[] pass_byte = Encoding.ASCII.GetBytes("your input value");

and then print result. by using foreach loop.

Instead of command: docker run

You should use:

docker start **CONTAINER ID**

because the container is already exist

More info

If you're adding a pile of anchors to the DOM, look into event delegation instead.

Here's a simple example:

$('#somecontainer').click(function(e) {   
  var $target = $(e.target);   
  if ($target.hasClass("myclass")) {
    // do something
  }
});

Make sure you have commented out any commentaries. Sometimes when copying and pasting you will leave out the "/*!"

Also when you go into the console they will list your errors and you should take it one at a time. If you see "Uncaught SyntaxError: Unexpected token * " That might mean it is reading your js file and it isn't getting past the first line.

/*! * jquery.tools 1.1.2 - The missing UI library for the Web * * [tools.tabs-1.0.4, tools.tooltip-1.1.2, tools.scrollable-1.1.2, tools.overlay-1.1.2, tools.expose-1.0.5] * * Copyright (c) 2009 Tero Piirainen * http://flowplayer.org/tools/ * File generated: Wed Oct 07 09:40:16 GMT 2009 */

Strings in C# are immutable and in some sense it means that they are fixed-size.
However you cannot constrain a string variable to only accept n-character strings. If you define a string variable, it can be assigned any string. If truncating strings (or throwing errors) is essential part of your business logic, consider doing so in your specific class' property setters (that's what Jon suggested, and it's the most natural way of creating constraints on values in .NET).

If you just want to make sure isn't too long (e.g. when passing it as a parameter to some legacy code), truncate it manually:

const int MaxLength = 5;


var name = "Christopher";
if (name.Length > MaxLength)
    name = name.Substring(0, MaxLength); // name = "Chris"

I would use a negative lookahead for any character:

^(?![\s\S])

This can only match if the input is totally empty, because the character class will match any character, including any of the various newline characters.

Was having this issue testing long doubles, and alas, I came across a fix! You have to compile your project with -D__USE_MINGW_ANSI_STDIO:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=0.000000

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c -D__USE_MINGW_ANSI_STDIO

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=42.000000

Code:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test
$ cat main.c
#include <stdio.h>

int main(int argc, char **argv)
{
   long double c=42;

   c/3;

   printf("c=%Lf\n",c);

   return 0;
}

@Tim's answer only does half the work -- that gets it into a datetime.datetime object.

To get it into the string format you require, you use datetime.strftime:

print(datetime.strftime('%b %d,%Y'))

instead of doing pure jquery, i would do:

$(".mytext").mouseover(function() {
    x= $(this).position().left - document.scrollLeft
    y= $(this).position().top - document.scrollTop
    $("#dialog").dialog('option', 'position', [y, x]);
}

if i am understanding your question correctly, the code you have is positioning the dialog as if the page had no scroll, but you want it to take the scroll into account. my code should do that.

I doubt css understands left by itself. You need to use it specifying position. You are using .css() correctly

position: relative/absolute/whatever;
left: 900px;

heres a fiddle of it working

http://jsfiddle.net/gFLZe/

and without the position here's what you get

http://jsfiddle.net/gkkm5/

Change your if statement to be like this - with quotes around -900px

var n = $("items").css("left");

if(n == '-900px'){
    $(".items span").fadeOut("slow");
}

Oracle 9i+ (maybe 8i too) has FIRST/LAST aggregate functions, that make computation over groups of rows according to row's rank in group. Assuming all rows as one group, you'll get what you want without subqueries:

SELECT
  max(MEMBSHIP_ID)
  keep (
      dense_rank first
      order by paym_date desc NULLS LAST
  ) as LATEST_MEMBER_ID
FROM user_payment
WHERE user_id=1

Today in my MS-Access 2003 with an ODBC tabla pointing to a SQL Server 2000 with sa password gave me the same error.
I defined a Primary Key on the table in the SQL Server database, and the issue was gone.

I'm surprised no one mentioned the HTML entities   and   which produce horizontal white space equivalent to the characters n and m, respectively. If you want to accumulate horizontal white space quickly, those are more efficient than  .

1. no space
2.   
3.  
4.  

Along with <space> and  , these are the five entities HTML provides for horizontal white space.

Note that except for  , all entities allow breaking. Whatever text surrounds them will wrap to a new line if it would otherwise extend beyond the container boundary. With   it would wrap to a new line as a block even if the text before   could fit on the previous line.

Depending on your use case, that may be desired or undesired. For me, unless I'm dealing with things like names (John Doe), addresses or references (see eq. 5), breaking as a block is usually undesired.

Let's see how we get the params, headers and body in Flask. I'm gonna explain with the help of postman.

The params keys and values are reflected in the API endpoint. for example key1 and key2 in the endpoint : https://127.0.0.1/upload?key1=value1&key2=value2

from flask import Flask, request
app = Flask(__name__)

@app.route('/upload')
def upload():

  key_1 = request.args.get('key1')
  key_2 = request.args.get('key2')
  print(key_1)
  #--> value1
  print(key_2)
  #--> value2

After params, let's now see how to get the headers:

  header_1 = request.headers.get('header1')
  header_2 = request.headers.get('header2')
  print(header_1)
  #--> header_value1
  print(header_2)
  #--> header_value2

Now let's see how to get the body

  file_name = request.files['file'].filename
  ref_id = request.form['referenceId']
  print(ref_id)
  #--> WWB9838yb3r47484

so we fetch the uploaded files with request.files and text with request.form

Well, I don't understand why are you used transaction in case when you make a select.

Transaction is useful when you make changes (add, edit or delete) data from database.

Remove transaction unless you use insert, update or delete statements

Take a look at calc() specification. Here is an example of usage:

border-right:1px solid;
border-left:1px solid;
width:calc(100% - 2px);

mvn clean package -DpropEnv=PROD

Then using like this in POM.xml

<properties>
    <myproperty>${propEnv}</myproperty>
</properties>

You can use slice method in javascript array object

<div ng-repeat="item in items.slice(0, 4)">{{item}}</div>

In my case nothing worked when the protocol was https, then I switched to ssh, and ensured, I pulled the repo from last commit and not entire history, and also specific branch. This helped me:

git clone --depth 1 "ssh:.git" --branch “specific_branch”

While the current Answer is right in most cases, there are certain situations that it will not give you the correct answer. If you use inside your script functions then:

$MyInvocation.MyCommand.Name 

Returns the name of the function instead name of the name of the script.

function test {
    $MyInvocation.MyCommand.Name
}

Will give you "test" no matter how your script is named. The right command for getting the script name is always

$MyInvocation.ScriptName

this returns the full path of the script you are executing. If you need just the script filename than this code should help you:

split-path $MyInvocation.PSCommandPath -Leaf

I would like to add that this problem is similar to common Java memory leaks.

When the JVM garbage collector is unable to clear the "waste" memory of your Java / Java EE application over time, OutOfMemoryError: Java heap space will be the outcome.

It is important to perform a proper diagnostic first:

• Enable verbose:gc. This will allow you to understand the memory growing pattern over time.
• Generate and analyze a JVM Heap Dump. This will allow you to understand your application memory footprint and pinpoint the source of the memory leak(s).
• You can also use Java profilers and runtime memory leak analyzer such as Plumbr as well to help you with this task.

I have implemented enums like that

module EnumType

  def self.find_by_id id
    if id.instance_of? String
      id = id.to_i
    end 
    values.each do |type|
      if id == type.id
        return type
      end
    end
    nil
  end

  def self.values
    [@ENUM_1, @ENUM_2] 
  end

  class Enum
    attr_reader :id, :label

    def initialize id, label
      @id = id
      @label = label
    end
  end

  @ENUM_1 = Enum.new(1, "first")
  @ENUM_2 = Enum.new(2, "second")

end

then its easy to do operations

EnumType.ENUM_1.label

...

enum = EnumType.find_by_id 1

...

valueArray = EnumType.values

You can't.

Although the SQL-92 syntax to add a foreign key to your table would be as follows:

ALTER TABLE child ADD CONSTRAINT fk_child_parent
                  FOREIGN KEY (parent_id) 
                  REFERENCES parent(id);

SQLite doesn't support the ADD CONSTRAINT variant of the ALTER TABLE command (sqlite.org: SQL Features That SQLite Does Not Implement).

Therefore, the only way to add a foreign key in sqlite 3.6.1 is during CREATE TABLE as follows:

CREATE TABLE child ( 
    id           INTEGER PRIMARY KEY, 
    parent_id    INTEGER, 
    description  TEXT,
    FOREIGN KEY (parent_id) REFERENCES parent(id)
);

Unfortunately you will have to save the existing data to a temporary table, drop the old table, create the new table with the FK constraint, then copy the data back in from the temporary table. (sqlite.org - FAQ: Q11)

Do C-b, :show which will show you all your current settings. /green, nnn will find you which properties have been set to green, the default. Do C-b, :set window-status-bg cyan and the bottom bar should change colour.

List available colours for tmux

You can tell more easily by the titles and the colours as they're actually set in your live session :show, than by searching through the man page, in my opinion. It is a very well-written man page when you have the time though.

If you don't like one of your changes and you can't remember how it was originally set, you can open do a new tmux session. To change settings for good edit ~/.tmux.conf with a line like set window-status-bg -g cyan. Here's mine: https://gist.github.com/9083598

Add a key, value pair to dictionary

aDict = {}
aDict[key] = value

What do you mean by dynamic addition.

To print the output of a single layer:

from tensorflow.keras import backend as K
layerIndex = 1
func = K.function([model.get_layer(index=0).input], model.get_layer(index=layerIndex).output)
layerOutput = func([input_data])  # input_data is a numpy array
print(layerOutput)

To print output of every layer:

from tensorflow.keras import backend as K
for layerIndex, layer in enumerate(model.layers):
    func = K.function([model.get_layer(index=0).input], layer.output)
    layerOutput = func([input_data])  # input_data is a numpy array
    print(layerOutput)

Using MVC5 you could use:

public enum UserPromotion
{
   None = 0x0,

   [Display(Name = "Send Job Offers By Mail")]
   SendJobOffersByMail = 0x1,

   [Display(Name = "Send Job Offers By Sms")]
   SendJobOffersBySms = 0x2,

   [Display(Name = "Send Other Stuff By Sms")]
   SendPromotionalBySms = 0x4,

   [Display(Name = "Send Other Stuff By Mail")]
   SendPromotionalByMail = 0x8
}

then if you want to create a dropdown selector you can use:

@Html.EnumDropdownListFor(expression: model => model.PromotionSelector, optionLabel: "Select") 

This can be achieved with greater cross-browser support than the accepted answer by using pseudo-elements as exemplified by this answer: https://stackoverflow.com/a/19818268/2602816

Try to organize by folder:

baseTypes.ts

export class Animal {
    move() { /* ... */ }
}

export class Plant {
    photosynthesize() { /* ... */ }
}

dog.ts

import b = require('./baseTypes');

export class Dog extends b.Animal {
    woof() { }
}   

tree.ts

import b = require('./baseTypes');

class Tree extends b.Plant {
}

LivingThings.ts

import dog = require('./dog')
import tree = require('./tree')

export = {
    dog: dog,
    tree: tree
}

main.ts

import LivingThings = require('./LivingThings');
console.log(LivingThings.Tree)
console.log(LivingThings.Dog)

The idea is that your module themselves shouldn't care / know they are participating in a namespace, but this exposes your API to the consumer in a compact, sensible way which is agnostic to which type of module system you are using for the project.

You need to do this:

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

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

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

Just in case someone stumbles upon this like I did and doesn't realise, the two variations above are for different use cases.

The following:

.blue-border, .background {
    border: 1px solid #00f;
    background: #fff;
}

is for when you want to add styles to elements that have either the blue-border or background class, for example:

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

would all get a blue border and white background applied to them.

However, the accepted answer is different.

.blue-border.background {
    border: 1px solid #00f;
    background: #fff;
}

This applies the styles to elements that have both classes so in this example only the <div> with both classes should get the styles applied (in browsers that interpret the CSS properly):

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

So basically think of it like this, comma separating applies to elements with one class OR another class and dot separating applies to elements with one class AND another class.

As suggested in "PostgreSQL database default location on Linux", under Linux you can find out using the following command:

ps aux | grep postgres | grep -- -D

What I did was to use

let realm = Realm(path: "/Users/me/Desktop/TestRealm.realm")

and then it gets created in full view on my desktop and I can double-click to launch the Realm Browser on it. Later, I can remove the parameter and let it use the default location when I'm satisfied that all is working as expected.
