I needed to kill multiple adb processes (adb kill-server & adb start-server still left a lingering process alive.)

$ ps aux | grep adb

$ killall adb

just change your JDK I installed the JDK of SUN not Oracle and it works for me....

First try this code inside AndroidManifest

  <application>
       
    <uses-library
        android:name="org.apache.http.legacy"
        android:required="false" />
 </application>

If this code works, so fine. But if not. Try this code from which class you want to pass the data or uri.

Intent window = new Intent(getApplicationContext(), Browser.class);
window.putExtra("LINK", "http://www.yourwebsite.com");
startActivity(window);

Had the same issue on 64 bit win7 machine on company network behind proxy with automatically detected settings.

After a number of trials and failures the following workaround proved to be successful:

• sharing my phone's wifi internet connection via USB

Add a Kotlin Extension

If you are going to be doing this frequently, adding an extension makes your code more readable. Button extends TextView; use Button if you want to be more narrow.

fun TextView.leftDrawable(@DrawableRes id: Int = 0) {
    this.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0)
}

To use the extension, simply call

view.leftDrawable(R.drawable.my_drawable)

Anytime you need to clear, don't pass a param or make another extension called removeDrawables

You can hijack your Android audio port using an Arduino board like this. Then, you have two options (as far as I'm concerned):

1) Buy another Arduino Shield that supports RFID. I haven't seen one that supports UHF so far.

2) Try to connect your Arduino hijack with a USB RFID reader and build some embedded hardware kit.

Right now, I'm working in the second option but with iPhone.

This error

Failure [INSTALL_FAILED_OLDER_SDK]

Means that you're trying to install an app that has a higher minSdkVersion specified in its manifest than the device's API level. Change that number to 8 and it should work. I'm not sure about the other error, but it may be related to this one.

I think ResponseEntityExceptionHandler meets your requirements. A sample piece of code for HTTP 400:

@ControllerAdvice
public class MyExceptionHandler extends ResponseEntityExceptionHandler {

  @ResponseStatus(value = HttpStatus.BAD_REQUEST)
  @ExceptionHandler({HttpMessageNotReadableException.class, MethodArgumentNotValidException.class,
      HttpRequestMethodNotSupportedException.class})
  public ResponseEntity<Object> badRequest(HttpServletRequest req, Exception exception) {
    // ...
  }
}

If you want to use a column with 24/11/15 (for 24th November 2015) in your Pivot that will sort correctly, you can make sure it is properly formatted by doing the following - highlight the column, go to Data – Text to Columns – click Next twice, then select “Date” and use the default of DMY (or select as applicable to your data) and click ok

When you pivot now you should see it sorting properly as we have properly formatted that column to be a date field so Excel can work with it

None of these answers really work. As others noted the Cors package will only use the Access-Control-Allow-Origin header if the request had an Origin header. But you can't generally just add an Origin header to the request because browsers may try to regulate that too.

If you want a quick and dirty way to allow cross site requests to a web api, it's really a lot easier to just write a custom filter attribute:

public class AllowCors : ActionFilterAttribute
{
    public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
    {
        if (actionExecutedContext == null)
        {
            throw new ArgumentNullException("actionExecutedContext");
        }
        else
        {
            actionExecutedContext.Response.Headers.Remove("Access-Control-Allow-Origin");
            actionExecutedContext.Response.Headers.Add("Access-Control-Allow-Origin", "*");
        }
        base.OnActionExecuted(actionExecutedContext);
    }
}

Then just use it on your Controller action:

[AllowCors]
public IHttpActionResult Get()
{
    return Ok("value");
}

I won't vouch for the security of this in general, but it's probably a lot safer than setting the headers in the web.config since this way you can apply them only as specifically as you need them.

And of course it is simple to modify the above to allow only certain origins, methods etc.

I have just made use of a reference to a pointer to make all the pointers in a deleted binary tree except the root safe. To make the pointer safe we just have to set it to 0. I could not make the function that deletes the tree (keeping only the root) to accept a ref to a pointer since I am using the root (this pointer) as the first input to traverse left and right.

void BinTree::safe_tree(BinTree * &vertex ) {
    if ( vertex!=0 ) {  // base case
        safe_tree(vertex->left);    // left subtree.
            safe_tree(vertex->right);   //  right subtree.
          // delete vertex;  // using this delete causes an error, since they were deleted on the fly using inorder_LVR. If inorder_LVR does not perform delete to the nodes, then, use delete vertex;
        vertex=0;  // making a safe pointer
    }
} // end in

Bottom line, a reference to a pointer is invalid when the formal parameter is the (this) pointer.

Try this

location.pathname.substring(location.pathname.lastIndexOf("/") + 1);

location.pathname gives the part (domain not included) of the page URL. To get only the filename you have to extract it using the substring method.

javascript:var string="false";alert(Boolean(string)?'FAIL':'WIN')

will not work because any non-empty string is true

javascript:var string="false";alert(string!=false.toString()?'FAIL':'WIN')

works because compared with string represenation

Main two reasons only as mentioned in above comments

1. NetworkCredentials you set should be correct. Verify with try actually signing into the account.
2. You need to set UseDefaultCredentials to false first and then set Credentials Or Put smtp.UseDefaultCredentials = false; above the smtp.Credentials assignment.

this doesn't work:

gcc -ldl dlopentest.c

But this does:

gcc dlopentest.c -ldl

That's one annoying "feature" for sure

I was struggling with it when writing heredoc syntax and found some interesting facts. With CC=Clang, this works:

$CC -ldl -x c -o app.exe - << EOF
#include <dlfcn.h>
#include <stdio.h>
int main(void)
{
  if(dlopen("libc.so.6", RTLD_LAZY | RTLD_GLOBAL))
    printf("libc.so.6 loading succeeded\n");
  else
    printf("libc.so.6 loading failed\n");
  return 0;
}
EOF

./app.exe

as well as all of these:

• $CC -ldl -x c -o app.exe - << EOF
• $CC -x c -ldl -o app.exe - << EOF
• $CC -x c -o app.exe -ldl - << EOF
• $CC -x c -o app.exe - -ldl << EOF

However, with CC=gcc, only the last variant works; -ldl after - (the stdin argument symbol).

As noted in previous responses, using "$MyInvocation" is subject to scoping issues and doesn't necessarily provide consistent data (return value vs. direct access value). I've found that the "cleanest" (most consistent) method for getting script info like script path, name, parms, command line, etc. regardless of scope (in main or subsequent/nested function calls) is to use "Get-Variable" on "MyInvocation"...

# Get the MyInvocation variable at script level
# Can be done anywhere within a script
$ScriptInvocation = (Get-Variable MyInvocation -Scope Script).Value

# Get the full path to the script
$ScriptPath = $ScriptInvocation.MyCommand.Path

# Get the directory of the script
$ScriptDirectory = Split-Path $ScriptPath

# Get the script name
# Yes, could get via Split-Path, but this is "simpler" since this is the default return value
$ScriptName = $ScriptInvocation.MyCommand.Name

# Get the invocation path (relative to $PWD)
# @GregMac, this addresses your second point
$InvocationPath = ScriptInvocation.InvocationName

So, you can get the same info as $PSCommandPath, but a whole lot more in the deal. Not sure, but it looks like "Get-Variable" was not available until PS3 so not a lot of help for really old (not updated) systems.

There are also some interesting aspects when using "-Scope" as you can backtrack to get the names, etc. of the calling function(s). 0=current, 1=parent, etc.

Hope this is somewhat helpful.

Previous answers can be improved in terms of performances and compatibility.

Check once if the Error object exists, if not declare it :

if (typeof Error === "undefined") {
    Error = function(message) {
        this.message = message;
    };
    Error.prototype.message = "";
}

Then, each assertion will check the condition, and always throw an Error object

function assert(condition, message) {
    if (!condition) throw new Error(message || "Assertion failed");
}

Keep in mind that the console will not display the real error line number, but the line of the assert function, which is not useful for debugging.

The cleanest way that I've found to do this is to create a new Class Library project in the target folder, and redirect all of its build output elsewhere. It still leaves a .csproj file sitting in that folder, but it does let you see it in Visual Studio and pick which files to include in your project.

if you want to find about object name e.g. table name and stored procedure on which particular user has permission, use the following query:

SELECT pr.principal_id, pr.name, pr.type_desc, 
    pr.authentication_type_desc, pe.state_desc, pe.permission_name, OBJECT_NAME(major_id) objectName
FROM sys.database_principals AS pr
JOIN sys.database_permissions AS pe ON pe.grantee_principal_id = pr.principal_id
--INNER JOIN sys.schemas AS s ON s.principal_id =  sys.database_role_members.role_principal_id 
     where pr.name in ('youruser1','youruser2') 

It depends on how you want to use the data in the excel file. If you want to import it into mysql, you could simply save it as a CSV formatted file and then use fgetcsv to parse it.

Don't forget about spaces:

source=""
samples=("")
if [ $1 = "country" ]; then
   source="country"
   samples="US Canada Mexico..."
else
  echo "try again"
fi

You need to open TCP port 8787 in the ec2 Security Group. Also need to open the same port on the EC2 instance's firewall.

Just one command did the work

netsh http add iplisten 127.0.0.1

If you want to delete the index of array:

Use array_name.pop(index_no.)

ex:-

>>> arr = [1,2,3,4]
>>> arr.pop(2)
>>>arr
[1,2,4]

If you want to delete a particular string/element from the array then

>>> arr1 = ['python3.6' , 'python2' ,'python3']
>>> arr1.remove('python2')
>>> arr1
['python3.6','python3']

Probably not helpful, but if the array is the only thing that you'll be displaying, you could always set

header('Content-type: text/plain');

I realize you're looking for a "deep" copy of an array, but if you just have a single level array you can use this:

Copying a native JS Array is easy. Use the Array.slice() method which creates a copy of part/all of the array.

var foo = ['a','b','c','d','e'];
var bar = foo.slice();

now foo and bar are 5 member arrays of 'a','b','c','d','e'

of course bar is a copy, not a reference... so if you did this next...

bar.push('f');
alert('foo:' + foo.join(', '));
alert('bar:' + bar.join(', '));

you would now get:

foo:a, b, c, d, e
bar:a, b, c, d, e, f

See documentation here: http://www.postgresql.org/docs/current/interactive/sql-altertable.html

ALTER TABLE tbl_name ALTER COLUMN col_name TYPE varchar (11);

I believe .clone() is what you're looking for, so long as the class supports it.

For me android:gravity="center" did the trick in the parent layout element.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/fullImageView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:contentDescription="@string/fullImageView"
        android:layout_gravity="center" />

</LinearLayout>

If you have simple dropdown like:

<select name="status" id="status">
    <option value="1">Active</option>
    <option value="0">Inactive</option>
</select>

Then you can use this code for getting value:

$(function(){

 $("#status").change(function(){
     var status = this.value;
     alert(status);
   if(status=="1")
     $("#icon_class, #background_class").hide();// hide multiple sections
  });

});

Here is a practical example of Anchor tag with different

This is older but placing this here for my reference too. boto3.resource is just implementing the default Session, you can pass through boto3.resource session details.

Help on function resource in module boto3:

resource(*args, **kwargs)
    Create a resource service client by name using the default session.

    See :py:meth:`boto3.session.Session.resource`.

https://github.com/boto/boto3/blob/86392b5ca26da57ce6a776365a52d3cab8487d60/boto3/session.py#L265

you can see that it just takes the same arguments as Boto3.Session

import boto3
S3 = boto3.resource('s3', region_name='us-west-2', aws_access_key_id=settings.AWS_SERVER_PUBLIC_KEY, aws_secret_access_key=settings.AWS_SERVER_SECRET_KEY)
S3.Object( bucket_name, key_name ).delete()

But now it is not working and I contacted our hosting team then they told me to use smtp

Newsflash - it was using SMTP before. They've not provided you with the information you need to solve the problem - or you've not relayed it accurately here.

Its possible that they've disabled the local MTA on the webserver, in which case you'll need to connect the SMTP port on a remote machine. There are lots of toolkits which will do the heavy lifting for you. Personally I like phpmailer because it adds other functionality.

Certainly if they've taken away a facility which was there before and your paying for a service then your provider should be giving you better support than that (there are also lots of programs to drop in in place of a full MTA which would do the job).

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

                'If it does, then check to see what our time value is
                If x > 0 Then
                    time2 = x.Value
                    'Apply the change to the output cell.
                    t.Value = time1 - time2

            'If the columns don't match, or the x value is not a time
            'then we'll move to the next dep time (x)
        Next x
    Next t

End Sub

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

     A                      B                   C                   D                  E

I can't comment yet, so I'll post a new answer

Accepted answer is ok-ish, but it wasn't stopping submit on numpad enter. At least in current version of Chrome. I had to alter the keycode condition to this, then it works.

if(event.keyCode == 13 || event.keyCode == 169) {...}

It depends on your Linux distibution and your preference of editors etc. but I would recommend to start with Kile (a KDE app) as it is easy to learn and installing it should install most of the needed packages for LaTex and PDF generation. Just have a look at the screenshots.

Try this query:

SELECT *
FROM table 
WHERE MONTH(FROM_UNIXTIME(columnName))= MONTH(CURDATE())

You can use placeholder Attribute, which doesn't add a default value but might be what you are looking out for :

<textarea placeholder="this text will show in the textarea"></textarea>

Check it out here - http://jsfiddle.net/8DzCE/949/

Important Note ( As suggested by Jon Brave in the comments ) :

Placeholder Attribute does not set the value of a textarea. Rather "The placeholder attribute represents a short hint (a word or short phrase) intended to aid the user with data entry when the control has no value" [and it disappears as soon as user clicks into the textarea]. It will never act as "the default value" for the control. If you want that, you must put the desired text inside the Here is the actual default value, as per other answers here

You can using onAttach or if you do not want to put onAttach everywhere then you can put a method that returns ApplicationContext on the main App class :

public class App {
    ...  
    private static Context context;

    @Override
    public void onCreate() {
        super.onCreate();
        context = this;
    }

    public static Context getContext() {
        return context;
    }
    ...
}

After that you can re-use it everywhere in all over your project, like this :

App.getContext().getString(id)

Please let me know if this does not work for you.

Use a SortedSet (TreeSet is the default one):

SortedSet<String> set=new TreeSet<String>();
set.add("12");
set.add("15");
set.add("5");
List<String> list=new ArrayList<String>(set);

No extra sorting code needed.

Oh, I see you want a different sort order. Supply a Comparator to the TreeSet:

new TreeSet<String>(Comparator.comparing(Integer::valueOf));

Now your TreeSet will sort Strings in numeric order (which implies that it will throw exceptions if you supply non-numeric strings)

Reference:

• Java Tutorial (Collections Trail):
  • Object Ordering
  • The SortedSet interface
• Javadocs: TreeSet
• Javadocs: Comparator

Your first CSS selector—social.h2—is looking for the "social" element in the "h2", class, e.g.:

<social class="h2">

Class selectors are proceeded with a dot (.). Also, use a space () to indicate that one element is inside of another. To find an <h2> descendant of an element in the social class, try something like:

.social h2 {
  color: pink;
  font-size: 14px;
}

To get a better understanding of CSS selectors and how they are used to reference your HTML, I suggest going through the interactive HTML and CSS tutorials from CodeAcademy. I hope that this helps point you in the right direction.

Add the following style to your h3 elements:

word-wrap: break-word;

This will cause the long URLs in them to wrap. The default setting for word-wrap is normal, which will wrap only at a limited set of split tokens (e.g. whitespaces, hyphens), which are not present in a URL.

This is an interesting question, i just want to give another angle by adding a little more info.You can understand why an exception is thrown if you see how static methods operate. These methods can manipulate either static data, local data or data that is sent to it as a parameter.why? because static method can be accessed by any object, from anywhere. So, there can be security issues posed or there can be leaks of information if it can use instance variables.Hence the compiler has to throw such a case out of consideration.

This is the correct way to change btn color.

 .btn-primary:not(:disabled):not(.disabled).active, 
    .btn-primary:not(:disabled):not(.disabled):active, 
    .show>.btn-primary.dropdown-toggle{
        color: #fff;
        background-color: #F7B432;
        border-color: #F7B432;
    }

In my case I had previously initialized a git directory where I was trying to create a new one. I just deleted all the old files and started from scratch.

I always do it like this:

$("#id").css("width", "50%");

The easiest way to do this is:

1. Create an App_GlobalResources system folder and add a resource file to it e.g. Messages.resx
2. Create your entries in the resource file e.g. ErrorMsg = This is an error.
3. Then to access that entry: string errormsg = Resources.Messages.ErrorMsg

If the .project and .classpath are already committed, then they need to be removed from the index (but not the disk)

git rm --cached .project
git rm --cached .classpath

Then the .gitignore would work (and that file can be added and shared through clones).
For instance, this gitignore.io/api/eclipse file will then work, which does include:

# Eclipse Core      
.project

# JDT-specific (Eclipse Java Development Tools)     
.classpath

Note that you could use a "Template Directory" when cloning (make sure your users have an environment variable $GIT_TEMPLATE_DIR set to a shared folder accessible by all).
That template folder can contain an info/exclude file, with ignore rules that you want enforced for all repos, including the new ones (git init) that any user would use.

As commented by Abdollah

When you change the index, you need to commit the change and push it.
Then the file is removed from the repository. So the newbies cannot checkout the files .classpath and .project from the repo.

Putting this answer here as it is the top result in Google.

If you want a quick and simple way:

    filter: brightness(0.2);

I faced the same error, in my case I miss-spelled ng-model directive something like "ng-moel"

Wrong one: ng-moel="user.name" Right one: ng-model="user.name"

I think you're confusing the issues of casting and converting here.

• Casting: The act of changing the type of a reference which points to an object. Either moving up or down the object hierarchy or to an implemented interface
• Converting: Creating a new object from the original source object of a different type and accessing it through a reference to that type.

It's often hard to know the difference between the 2 in C# because both of them use the same C# operator: the cast.

In this situation you are almost certainly not looking for a cast operation. Casting a dynamic to another dynamic is essentially an identity conversion. It provides no value because you're just getting a dynamic reference back to the same underlying object. The resulting lookup would be no different.

Instead what you appear to want in this scenario is a conversion. That is morphing the underlying object to a different type and accessing the resulting object in a dynamic fashion. The best API for this is Convert.ChangeType.

public static dynamic Convert(dynamic source, Type dest) {
  return Convert.ChangeType(source, dest);
}

EDIT

The updated question has the following line:

obj definitely implements castTo

If this is the case then the Cast method doesn't need to exist. The source object can simply be assigned to a dynamic reference.

dynamic d = source;

It sounds like what you're trying to accomplish is to see a particular interface or type in the hierarchy of source through a dynamic reference. That is simply not possible. The resulting dynamic reference will see the implementation object directly. It doesn't look through any particular type in the hierarchy of source. So the idea of casting to a different type in the hierarchy and then back to dynamic is exactly identical to just assigning to dynamic in the first place. It will still point to the same underlying object.

This happens because your click handler fires before the value of the radio button changes. You need to listen to the change event instead:

<input 
  type="radio" 
  name="optionsRadios" 
  id="optionsRadios2" 
  value=""
  v-model="srStatus" 
  v-on:change="foo"> //here

Also, make sure you really want to call foo() on ready... seems like maybe you don't actually want to do that.

ready:function(){
    foo();
},

On MS Windows, the solution is to remove %APPDATA%\npm and reinstall node

You need module.exports:

Exports

An object which is shared between all instances of the current module and made accessible through require(). exports is the same as the module.exports object. See src/node.js for more information. exports isn't actually a global but rather local to each module.

For example, if you would like to expose variableName with value "variableValue" on sourceFile.js then you can either set the entire exports as such:

module.exports = { variableName: "variableValue" };

Or you can set the individual value with:

module.exports.variableName = "variableValue";

To consume that value in another file, you need to require(...) it first (with relative pathing):

const sourceFile = require('./sourceFile');
console.log(sourceFile.variableName);

Alternatively, you can deconstruct it.

const { variableName } = require('./sourceFile');
//            current directory --^
// ../     would be one directory down
// ../../  is two directories down

If all you want out of the file is variableName then

./sourceFile.js:

const variableName = 'variableValue'
module.exports = variableName

./consumer.js:

const variableName = require('./sourceFile')

Edit (2020):

Since Node.js version 8.9.0, you can also use ECMAScript Modules with varying levels of support. The documentation.

• For Node v13.9.0 and beyond, experimental modules are enabled by default
• For versions of Node less than version 13.9.0, use --experimental-modules

Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Once you have it setup, you can use import and export.

Using the example above, there are two approaches you can take

./sourceFile.js:

// This is a named export of variableName
export const variableName = 'variableValue'
// Alternatively, you could have exported it as a default. 
// For sake of explanation, I'm wrapping the variable in an object
// but it is not necessary. 
// You can actually omit declaring what variableName is here. 
// { variableName } is equivalent to { variableName: variableName } in this case. 
export default { variableName: variableName } 

./consumer.js:

// There are three ways of importing. 
// If you need access to a non-default export, then 
// you use { nameOfExportedVariable } 
import { variableName } from './sourceFile'
console.log(variableName) // 'variableValue'

// Otherwise, you simply provide a local variable name 
// for what was exported as default.
import sourceFile from './sourceFile'
console.log(sourceFile.variableName) // 'variableValue'

./sourceFileWithoutDefault.js:

// The third way of importing is for situations where there
// isn't a default export but you want to warehouse everything
// under a single variable. Say you have:
export const a = 'A'
export const b = 'B'

./consumer2.js

// Then you can import all exports under a single variable
// with the usage of * as:
import * as sourceFileWithoutDefault from './sourceFileWithoutDefault'

console.log(sourceFileWithoutDefault.a) // 'A'
console.log(sourceFileWithoutDefault.b) // 'B'

// You can use this approach even if there is a default export:
import * as sourceFile from './sourceFile'

// Default exports are under the variable default:
console.log(sourceFile.default) // { variableName: 'variableValue' }

// As well as named exports:
console.log(sourceFile.variableName) // 'variableValue

I know this is an old thread but an easier solution would be to embed an input within the label like so:

<label>Label one: <input id="input1" type="text"></label>

The name of the resource is the name space plus the "pseudo" name space of the path to the file. The "pseudo" name space is made by the sub folder structure using \ (backslashes) instead of . (dots).

public static Stream GetResourceFileStream(String nameSpace, String filePath)
{
    String pseduoName = filePath.Replace('\\', '.');
    Assembly assembly = Assembly.GetExecutingAssembly();
    return assembly.GetManifestResourceStream(nameSpace + "." + pseduoName);
}

The following call:

GetResourceFileStream("my.namespace", "resources\\xml\\my.xml")

will return the stream of my.xml located in the folder-structure resources\xml in the name space: my.namespace.

Use a List (where T is any type or Object) when you want to add/remove data, since resizing arrays is expensive. You can read more about Arrays considered somewhat harmful whereas a List can be added to New records can be appended to the end. It adjusts its size as needed.

A List can be initalized in following ways

Using collection initializer.

List<string> list1 = new List<string>()
{
    "carrot",
    "fox",
    "explorer"
};

Using var keyword with collection initializer.

var list2 = new List<string>()
{
    "carrot",
    "fox",
    "explorer"
};

Using new array as parameter.

string[] array = { "carrot", "fox", "explorer" };
List<string> list3 = new List<string>(array);

Using capacity in constructor and assign.

List<string> list4 = new List<string>(3);
list4.Add(null); // Add empty references. (Not Recommended)
list4.Add(null);
list4.Add(null);
list4[0] = "carrot"; // Assign those references.
list4[1] = "fox";
list4[2] = "explorer";

Using Add method for each element.

List<string> list5 = new List<string>();
list5.Add("carrot");
list5.Add("fox");
list5.Add("explorer");

Thus for an Object List you can allocate and assign the properties of objects inline with the List initialization. Object initializers and collection initializers share similar syntax.

class Test
{
    public int A { get; set; }
    public string B { get; set; }
}

Initialize list with collection initializer.

List<Test> list1 = new List<Test>()
{
    new Test(){ A = 1, B = "Jessica"},
    new Test(){ A = 2, B = "Mandy"}
};

Initialize list with new objects.

List<Test> list2 = new List<Test>();
list2.Add(new Test() { A = 3, B = "Sarah" });
list2.Add(new Test() { A = 4, B = "Melanie" });

This is an old thread, but for reference it's important to note that disabling an input element's outline is not recommended as it hinders accessibility.

The outline property is there for a reason - providing users with a clear indication of keyboard focus. For further reading and additional sources about this subject see http://outlinenone.com/

The following code outputs the number of words whose first and last letters are equal. Tested and verified using a python online compiler:

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']  
count = 0  
for i in words:  
     if i[0]==i[-1]:
        count = count + 1  
print(count)  

Output:

$python main.py

Use the default version:

Collections.sort(myarrayList);

Of course this requires that your Elements implement Comparable, but the same holds true for the version you mentioned.

BTW: you should use generics in your code, that way you get compile-time errors if your class doesn't implement Comparable. And compile-time errors are much better than the runtime errors you'll get otherwise.

List<MyClass> list = new ArrayList<MyClass>();
// now fill up the list

// compile error here unless MyClass implements Comparable
Collections.sort(list); 

TL;DR:

They use a stack architecture with cached graphs for everything above the MySQL bottom of their stack.

Long Answer:

I did some research on this myself because I was curious how they handle their huge amount of data and search it in a quick way. I've seen people complaining about custom made social network scripts becoming slow when the user base grows. After I did some benchmarking myself with just 10k users and 2.5 million friend connections - not even trying to bother about group permissions and likes and wall posts - it quickly turned out that this approach is flawed. So I've spent some time searching the web on how to do it better and came across this official Facebook article:

• TAO: Facebook’s Distributed Data Store for the Social Graph
• TAO: The power of the graph.

I really recommend you to watch the presentation of the first link above before continue reading. It's probably the best explanation of how FB works behind the scenes you can find.

The video and article tells you a few things:

• They're using MySQL at the very bottom of their stack
• Above the SQL DB there is the TAO layer which contains at least two levels of caching and is using graphs to describe the connections.
• I could not find anything on what software / DB they actually use for their cached graphs

Let's take a look at this, friend connections are top left:

Well, this is a graph. :) It doesn't tell you how to build it in SQL, there are several ways to do it but this site has a good amount of different approaches. Attention: Consider that a relational DB is what it is: It's thought to store normalised data, not a graph structure. So it won't perform as good as a specialised graph database.

Also consider that you have to do more complex queries than just friends of friends, for example when you want to filter all locations around a given coordinate that you and your friends of friends like. A graph is the perfect solution here.

I can't tell you how to build it so that it will perform well but it clearly requires some trial and error and benchmarking.

Here is my disappointing test for just findings friends of friends:

DB Schema:

CREATE TABLE IF NOT EXISTS `friends` (
`id` int(11) NOT NULL,
  `user_id` int(11) NOT NULL,
  `friend_id` int(11) NOT NULL
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

Friends of Friends Query:

(
        select friend_id
        from friends
        where user_id = 1
    ) union (
        select distinct ff.friend_id
        from
            friends f
            join friends ff on ff.user_id = f.friend_id
        where f.user_id = 1
    )

I really recommend you to create you some sample data with at least 10k user records and each of them having at least 250 friend connections and then run this query. On my machine (i7 4770k, SSD, 16gb RAM) the result was ~0.18 seconds for that query. Maybe it can be optimized, I'm not a DB genius (suggestions are welcome). However, if this scales linear you're already at 1.8 seconds for just 100k users, 18 seconds for 1 million users.

This might still sound OKish for ~100k users but consider that you just fetched friends of friends and didn't do any more complex query like "display me only posts from friends of friends + do the permission check if I'm allowed or NOT allowed to see some of them + do a sub query to check if I liked any of them". You want to let the DB do the check on if you liked a post already or not or you'll have to do in code. Also consider that this is not the only query you run and that your have more than active user at the same time on a more or less popular site.

I think my answer answers the question how Facebook designed their friends relationship very well but I'm sorry that I can't tell you how to implement it in a way it will work fast. Implementing a social network is easy but making sure it performs well is clearly not - IMHO.

I've started experimenting with OrientDB to do the graph-queries and mapping my edges to the underlying SQL DB. If I ever get it done I'll write an article about it.

You could store the data in an array of strings of some large fixed size. It should be efficient to access any particular character in that array of strings, and to treat that character as a byte.

It would be interesting to see the operations you want to support, perhaps expressed as an interface, to make the question more concrete.

On your existing button code, simply insert this line before the procedure:

If MsgBox("This will erase everything! Are you sure?", vbYesNo) = vbNo Then Exit Sub

This will force it to quit if the user presses no.

15841:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188:
...
SSL handshake has read 0 bytes and written 121 bytes

This is a handshake failure. The other side closes the connection without sending any data ("read 0 bytes"). It might be, that the other side does not speak SSL at all. But I've seen similar errors on broken SSL implementation, which do not understand newer SSL version. Try if you get a SSL connection by adding -ssl3 to the command line of s_client.

instanceof can be used to determine the actual type of an object:

class A { }  
class C extends A { } 
class D extends A { } 

public static void testInstance(){
    A c = new C();
    A d = new D();
    Assert.assertTrue(c instanceof A && d instanceof A);
    Assert.assertTrue(c instanceof C && d instanceof D);
    Assert.assertFalse(c instanceof D);
    Assert.assertFalse(d instanceof C);
}

I would like to share my thoughts as well, since I've bumped into the same issue.

Well, just answering the question would be:

1 - Add an extenssion to the observable collection class like this:

namespace YourNameSpace
{
    public static class ObservableCollectionExtension
    {
        public static void OrderByReference<T>(this ObservableCollection<T> collection, List<T> comparison)
        {
            for (int i = 0; i < comparison.Count; i++)
            {
                if (!comparison.ElementAt(i).Equals(collection.ElementAt(i)))
                    collection.Move(collection.IndexOf(comparison[i]), i);
            }
        }
        
        public static void InsertInPlace<T>(this ObservableCollection<T> collection, List<T> comparison, T item)
        {
            int index = comparison.IndexOf(item);
            comparison.RemoveAt(index);
            collection.OrderByReference(comparison);
            collection.Insert(index, item);
        }
    }
}

2 - Then use it like this:

_animals.OrderByReference(_animals.OrderBy(x => x).ToList());

This changes your ObservableCollection, you can use linq and it doesn't change the bindings!

Extra:

I've extended @Marco and @Contango answers to my own liking. First I thought of using a list directly as the comparison, so you would have this:

public static void OrderByReference<T>(this ObservableCollection<T> collection, List<T> comparison)
{
    for (int i = 0; i < comparison.Count; i++)
    {
        collection.Move(collection.IndexOf(comparison[i]), i);
    }
}

And using like this:

YourObservableCollection.OrderByReference(YourObservableCollection.DoYourLinqOrdering().ToList());

Then I've thought, since this always move everything and triggers the move in the ObservableCollection why not compare if the object is already in there, and this brings what I've put in the begining with the Equals comparator.

Adding the object to the correct place also sounded good, but I wanned a simple way to do it. So I've came up with that:

public static void InsertInPlace<T>(this ObservableCollection<T> collection, List<T> comparison, T item)
{
    collection.Insert(comparison.IndexOf(item), item);
}

You send a list with the new object where you want and also this new object, so you need to create a list, then add this new object, like this:

var YourList = YourObservableCollection.ToList();
var YourObject = new YourClass { ..... };
YourList.Add(YourObject);
YourObservableCollection.InsertInPlace(YourList.DoYourLinqOrdering().ToList(), YourObject);

But since the ObservableCollection could be in a different order than the list because of the selection in the "DoYourLinqOrdering()" (this would happen if the collection wasn't previously ordered) I've added the first extession (OrderByReference) in the insert as you can see in the begining of the answer. It will not take long if it doesn't need to move the itens arround, so I did't saw a problem in using it.

As performance goes, I've compared the methods by checking the time it takes for each to finish, so not ideal, but anyway, I've tested an observable collection with 20000 itens. For the OrderByReference I didn't saw great difference in the performance by adding the Equal object checker, but if not all itens need to be moved it is faster and it doesn't fire unecessary Move events on the collecitonChanged, so thats something. For the InsertInPlace is the same thing, if the ObservableCollection is already sorted, just checking if the objects are in the right place is faster than moving all the itens around, so there was not a huge difference in time if it is just passing through the Equals statement and you get the benefit of being sure everything is where it should be.

Be aware that if you use this extession with objects that dont mach or with a list that have more or less objects you will get an ArgumentOutOfRangeException or some other unexpect behaviour.

Hopes this helps somebody!

$(document).ready(function() {
  //...
//clear on focus
$('.input').focus(function() {
    $('.input').val("");
});
   //clear when submitted
$('.button').click(function() {
    $('.input').val("");
});

});

Single liner works

df['Name'] = 'abc'

Creates a Name column and sets all rows to abc value

It's simply means that it's a member field in the class.

I believe what you want to do is still to incude this js file in you html dom, if so then this apporach will work.

1. Write your jquery code in your javascript file as you would in your html dom
2. Include jquery framework before closing body tag
3. Include javascript file after including jqyery file

Example: //js file

     $(document).ready(function(){
     alert("jquery in js file");
     });

//html dom

    <body>
   <!--some divs content--->

   <script src=/path/to/jquery.js ></script>
   <script src=/path/to/js.js ></script>
   </body>

Omit

single property

type T1 = Omit<XYZ, "z"> // { x: number; y: number; }

multiple properties

type T2 = Omit<XYZ, "y" | "z"> // { x: number; } 

properties conditionally

type Keys_StringExcluded<T> = 
  { [K in keyof T]: T[K] extends string ? never : K }[keyof T]

type XYZ = { x: number; y: string; z: number; }
type T3a = Pick<XYZ, Keys_StringExcluded<XYZ>> // { x: number; z: number; }

type T3b = { [K in keyof XYZ as XYZ[K] extends string ? never : K]: XYZ[K] } 
// { x: number; z: number; }

properties by string pattern

type OmitGet<T> = {[K in keyof T as K extends `get${infer _}` ? never : K]: T[K]}

type XYZ2 = { getA: number; b: string; getC: boolean; }
type T4 = OmitGet<XYZ2> //  { b: string; }

Note: Above template literal types are supported with TS 4.1.
Note 2: You can also write get${string} instead of get${infer _} here.

You can use /* tslint:disable-next-line */ to locally disable tslint. However, as this is a compiler error disabling tslint might not help.

You can always temporarily cast $ to any:

delete ($ as any).summernote.options.keyMap.pc.TAB

which will allow you to access whatever properties you want.

Edit: As of Typescript 2.6, you can now bypass a compiler error/warning for a specific line:

if (false) {
    // @ts-ignore: Unreachable code error
    console.log("hello");
}

Note that the official docs "recommend you use [this] very sparingly". It is almost always preferable to cast to any instead as that better expresses intent.

You can now use Object.assign(target, ...sources). Following your example, you could use it like this:

class Foo {
  name: string;
  getName(): string { return this.name };
}

let fooJson: string = '{"name": "John Doe"}';
let foo: Foo = Object.assign(new Foo(), JSON.parse(fooJson));

console.log(foo.getName()); //returns John Doe

Object.assign is part of ECMAScript 2015 and is currently available in most modern browsers.

2) How to access Model data in Javascript/Jquery code block in .js file

How to access Model data in Javascript/Jquery code block in .cshtml file

There are two types of c# variable (Model) assignments to JavaScript variable.

1. Property assignment - Basic datatypes like int, string, DateTime (ex: Model.Name)
2. Object assignment - Custom or inbuilt classes (ex: Model, Model.UserSettingsObj)

Lets look into the details of these two assignments.

For the rest of the answer lets consider the below AppUser Model as an example.

public class AppUser
{
    public string Name { get; set; }
    public bool IsAuthenticated { get; set; }
    public DateTime LoginDateTime { get; set; }
    public int Age { get; set; }
    public string UserIconHTML { get; set; }
}

And the values we assign this Model are

AppUser appUser = new AppUser
{
    Name = "Raj",
    IsAuthenticated = true,
    LoginDateTime = DateTime.Now,
    Age = 26,
    UserIconHTML = "<i class='fa fa-users'></i>"
};

Property assignment

Lets use different syntax for assignment and observe the results.

1) Without wrapping property assignment in quotes.

var Name = @Model.Name;  
var Age = @Model.Age;
var LoginTime = @Model.LoginDateTime; 
var IsAuthenticated = @Model.IsAuthenticated;   
var IconHtml = @Model.UserIconHTML;  

As you can see there are couple of errors, Raj and True is considered to be javascript variables and since they dont exist its an variable undefined error. Where as for the dateTime varialble the error is unexpected number numbers cannot have special characters, The HTML tags are converted into its entity names so that the browser doesn't mix up your values and the HTML markup.

2) Wrapping property assignment in Quotes.

var Name = '@Model.Name';
var Age = '@Model.Age';
var LoginTime = '@Model.LoginDateTime';
var IsAuthenticated = '@Model.IsAuthenticated';
var IconHtml = '@Model.UserIconHTML'; 

The results are valid, So wrapping the property assignment in quotes gives us valid syntax. But note that the Number Age is now a string, So if you dont want that we can just remove the quotes and it will be rendered as a number type.

3) Using @Html.Raw but without wrapping it in quotes

 var Name = @Html.Raw(Model.Name);
 var Age = @Html.Raw(Model.Age);
 var LoginTime = @Html.Raw(Model.LoginDateTime);
 var IsAuthenticated = @Html.Raw(Model.IsAuthenticated);
 var IconHtml = @Html.Raw(Model.UserIconHTML);

The results are similar to our test case 1. However using @Html.Raw()on the HTML string did show us some change. The HTML is retained without changing to its entity names.

From the docs Html.Raw()

Wraps HTML markup in an HtmlString instance so that it is interpreted as HTML markup.

But still we have errors in other lines.

4) Using @Html.Raw and also wrapping it within quotes

var Name ='@Html.Raw(Model.Name)';
var Age = '@Html.Raw(Model.Age)';
var LoginTime = '@Html.Raw(Model.LoginDateTime)';
var IsAuthenticated = '@Html.Raw(Model.IsAuthenticated)';
var IconHtml = '@Html.Raw(Model.UserIconHTML)';

The results are good with all types. But our HTML data is now broken and this will break the scripts. The issue is because we are using single quotes ' to wrap the the data and even the data has single quotes.

We can overcome this issue with 2 approaches.

1) use double quotes " " to wrap the HTML part. As the inner data has only single quotes. (Be sure that after wrapping with double quotes there are no " within the data too)

  var IconHtml = "@Html.Raw(Model.UserIconHTML)";

2) Escape the character meaning in your server side code. Like

  UserIconHTML = "<i class=\"fa fa-users\"></i>"

Conclusion of property assignment

• Use quotes for non numeric dataType.
• Do Not use quotes for numeric dataType.
• Use Html.Raw to interpret your HTML data as is.
• Take care of your HTML data to either escape the quotes meaning in server side, Or use a different quote than in data during assignment to javascript variable.

Object assignment

Lets use different syntax for assignment and observe the results.

1) Without wrapping object assignment in quotes.

  var userObj = @Model; 

When you assign a c# object to javascript variable the value of the .ToString() of that oject will be assigned. Hence the above result.

2 Wrapping object assignment in quotes

var userObj = '@Model'; 

3) Using Html.Raw without quotes.

   var userObj = @Html.Raw(Model); 

4) Using Html.Raw along with quotes

   var userObj = '@Html.Raw(Model)'; 

The Html.Raw was of no much use for us while assigning a object to variable.

5) Using Json.Encode() without quotes

var userObj = @Json.Encode(Model); 

//result is like
var userObj = {"Name":"Raj",
               "IsAuthenticated":true,
               "LoginDateTime":"\/Date(1482572875150)\/",
               "Age":26,
               "UserIconHTML":"\u003ci class=\"fa fa-users\"\u003e\u003c/i\u003e"
              };

We do see some change, We see our Model is being interpreted as a object. But we have those special characters changed into entity names. Also wrapping the above syntax in quotes is of no much use. We simply get the same result within quotes.

From the docs of Json.Encode()

Converts a data object to a string that is in the JavaScript Object Notation (JSON) format.

As you have already encountered this entity Name issue with property assignment and if you remember we overcame it with the use of Html.Raw. So lets try that out. Lets combine Html.Raw and Json.Encode

6) Using Html.Raw and Json.Encode without quotes.

var userObj = @Html.Raw(Json.Encode(Model));

Result is a valid Javascript Object

 var userObj = {"Name":"Raj",
     "IsAuthenticated":true,
     "LoginDateTime":"\/Date(1482573224421)\/",
     "Age":26,
     "UserIconHTML":"\u003ci class=\"fa fa-users\"\u003e\u003c/i\u003e"
 };

7) Using Html.Raw and Json.Encode within quotes.

var userObj = '@Html.Raw(Json.Encode(Model))';

As you see wrapping with quotes gives us a JSON data

Conslusion on Object assignment

• Use Html.Raw and Json.Encode in combintaion to assign your object to javascript variable as JavaScript object.
• Use Html.Raw and Json.Encode also wrap it within quotes to get a JSON

Note: If you have observed the DataTime data format is not right. This is because as said earlier Converts a data object to a string that is in the JavaScript Object Notation (JSON) format and JSON does not contain a date type. Other options to fix this is to add another line of code to handle this type alone using javascipt Date() object

var userObj.LoginDateTime = new Date('@Html.Raw(Model.LoginDateTime)'); 
//without Json.Encode

How to access Model data in Javascript/Jquery code block in .js file

Razor syntax has no meaning in .js file and hence we cannot directly use our Model insisde a .js file. However there is a workaround.

1) Solution is using javascript Global variables.

We have to assign the value to a global scoped javascipt variable and then use this variable within all code block of your .cshtml and .js files. So the syntax would be

<script type="text/javascript">
  var userObj = @Html.Raw(Json.Encode(Model)); //For javascript object
  var userJsonObj = '@Html.Raw(Json.Encode(Model))'; //For json data
</script>

With this in place we can use the variables userObj and userJsonObj as and when needed.

Note: I personally dont suggest using global variables as it gets very hard for maintainance. However if you have no other option then you can use it with having a proper naming convention .. something like userAppDetails_global.

2) Using function() or closure Wrap all the code that is dependent on the model data in a function. And then execute this function from the .cshtml file .

external.js

 function userDataDependent(userObj){
  //.... related code
 }

.cshtml file

 <script type="text/javascript">
  userDataDependent(@Html.Raw(Json.Encode(Model))); //execute the function     
</script>

Note: Your external file must be referenced prior to the above script. Else the userDataDependent function is undefined.

Also note that the function must be in global scope too. So either solution we have to deal with global scoped players.

Using command-line :

docker run -it --name <WHATEVER> -p <LOCAL_PORT>:<CONTAINER_PORT> -v <LOCAL_PATH>:<CONTAINER_PATH> -d <IMAGE>:<TAG>

• IMAGE: k3_s3
• TAG: latest
• LOCAL_PORT: 8080
• CONTAINER_PORT: 8080
• LOCAL_PATH: /volume-to-mount
• CONTAINER_PATH: /mnt

Examples :

1. First create /volume-to-mount. (Skip if exist)

$ mkdir -p /volume-to-mount

2. docker-compose -f docker-compose.yaml up -d

version: '2'
  services:
    cms:
       image: ghost-cms:latest
       ports:
       - 8080:8080
       volumes:
       - /volume-to-mount:/mnt

3. Verify your container :

docker exec -it CONTAINER_ID ls -la /mnt

Read line by line, not the whole file:

for line in open(file_name, 'rb'):
    # process line here

Even better use with for automatically closing the file:

with open(file_name, 'rb') as f:
    for line in f:
        # process line here

The above will read the file object using an iterator, one line at a time.

Not only can it, it always does. If you do not specify one then it has a default no arg constructor, just like any other class. In fact, ALL classes, including nested and anonymous classes, will get a default constructor if one is not specified (in the case of anonymous classes it is impossible to specify one, so you will always get the default constructor).

A good example of an abstract class having a constructor is the Calendar class. You get a Calendar object by calling Calendar.getInstance(), but it also has constructors which are protected. The reason its constructors are protected is so that only its subclasses can call them (or classes in the same package, but since it's abstract, that doesn't apply). GregorianCalendar is an example of a class that extends Calendar.

The most portable regex would be ^[ \t\n]*$ to match an empty string (note that you would need to replace \t and \n with tab and newline accordingly) and [^ \n\t] to match a non-whitespace string.

here is my example:

if(userAnswer==="Yes"||"yes"||"YeS"){
 console.log("Too Bad!");   
}

This says that if the answer is Yes yes or YeS than the same thing will happen

For example, to execute following with command prompt or BATCH file we can use this:

C:\Python27\python.exe "C:\Program files(x86)\dev_appserver.py" --host 0.0.0.0 --post 8080 "C:\blabla\"

Same thing to do with Python, we can do this:

subprocess.Popen(['C:/Python27/python.exe', 'C:\\Program files(x86)\\dev_appserver.py', '--host', '0.0.0.0', '--port', '8080', 'C:\\blabla'], shell=True)

or

subprocess.Popen(['C:/Python27/python.exe', 'C:/Program files(x86)/dev_appserver.py', '--host', '0.0.0.0', '--port', '8080', 'C:/blabla'], shell=True)

 log4j.rootLogger=OFF

I had the same problem before. Here was my solution:

1. Go to Setting ? find Developer options in System, and click.
2. TURN ON install via USB in the Debuging section.
3. Try Run app in Android Studio again!

Based on the link provided by @better_use_mkstemp, here's a fiddle where nested iframe resizes to fill parent div: http://jsfiddle.net/orlenko/HNyJS/

Html:

<div id="content">
    <iframe src="http://www.microsoft.com" name="frame2" id="frame2" frameborder="0" marginwidth="0" marginheight="0" scrolling="auto" onload="" allowtransparency="false"></iframe>
</div>
<div id="block"></div>
<div id="header"></div>
<div id="footer"></div>

Relevant parts of CSS:

div#content {
    position: fixed;
    top: 80px;
    left: 40px;
    bottom: 25px;
    min-width: 200px;
    width: 40%;
    background: black;
}

div#content iframe {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    height: 100%;
    width: 100%;
}

You can use a post-commit hook.

Put the post-commit hook script in the hooks folder, create a wget_folder in your C:\ drive, and put the wget.exe file in this folder. Add the following code in the file called post-commit.bat

SET REPOS=%1   
SET REV=%2

FOR /f "tokens=*" %%a IN (  
'svnlook uuid %REPOS%'  
) DO (  
SET UUID=%%a  
)  

FOR /f "tokens=*" %%b IN (  
'svnlook changed --revision %REV% %REPOS%'  
) DO (  
SET POST=%%b   
)

echo %REPOS% ----- 1>&2

echo %REV% -- 1>&2

echo %UUID% --1>&2

echo %POST% --1>&2

C:\wget_folder\wget ^   
    --header="Content-Type:text/plain" ^   
    --post-data="%POST%" ^   
    --output-document="-" ^   
    --timeout=2 ^     
    http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%    

where Test = name of the job

echo is used to see the value and you can also add exit 2 at the end to know about the issue and whether the post-commit hook script is running or not.

But if your Android App is only for personal purpose or created by you alone, you can use:

me.app_name.app

At some point I read a reasonably convincing argument on Perlmonks that testing the type of a scalar with ref or reftype is a bad idea. I don't recall who put the idea forward, or the link. Sorry.

The point was that in Perl there are many mechanisms that make it possible to make a given scalar act like just about anything you want. If you tie a filehandle so that it acts like a hash, the testing with reftype will tell you that you have a filehanle. It won't tell you that you need to use it like a hash.

So, the argument went, it is better to use duck typing to find out what a variable is.

Instead of:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;
    if( $type eq 'HASH' ) {
        $result = $var->{foo};
    }
    elsif( $type eq 'ARRAY' ) {
        $result = $var->[3];
    }
    else {
        $result = 'foo';
    }

    return $result;
}

You should do something like this:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;

    eval {
        $result = $var->{foo};
        1; # guarantee a true result if code works.
    }
    or eval { 
        $result = $var->[3];
        1;
    }
    or do {
        $result = 'foo';
    }

    return $result;
}

For the most part I don't actually do this, but in some cases I have. I'm still making my mind up as to when this approach is appropriate. I thought I'd throw the concept out for further discussion. I'd love to see comments.

Update

I realized I should put forward my thoughts on this approach.

This method has the advantage of handling anything you throw at it.

It has the disadvantage of being cumbersome, and somewhat strange. Stumbling upon this in some code would make me issue a big fat 'WTF'.

I like the idea of testing whether a scalar acts like a hash-ref, rather that whether it is a hash ref.

I don't like this implementation.

I spent a good amount of time trying to work this out today, and couldn't get things working using line-height or vertical-align. The easiest solution I was able to find was to set the <a/> to be relatively positioned so it would contain absolutes, and the :after to be positioned absolutely taking it out of the flow.

a{
    position:relative;
    padding-right:18px;
}
a:after{
    position:absolute;
    content:url(image.png);
}

The after image seemed to automatically center in that case, at least under Firefox/Chrome. Such may be a bit sloppier for browsers not supporting :after, due to the excess spacing on the <a/>.

1. You need to create a class that holds the user values, just like the response class User.

2. Add a property to the Response class 'user' with the type of the new class for the user values User.

   public class Response {
   
       public string id { get; set; }
       public string text { get; set; }
       public string url { get; set; }
       public string width { get; set; }
       public string height { get; set; }
       public string size { get; set; }
       public string type { get; set; }
       public string timestamp { get; set; }
       public User user { get; set; }
   
   }
   
   public class User {
   
       public int id { get; set; }
       public string screen_name { get; set; }
   
   }
   

In general you should make sure the property types of the json and your CLR classes match up. It seems that the structure that you're trying to deserialize contains multiple number values (most likely int). I'm not sure if the JavaScriptSerializer is able to deserialize numbers into string fields automatically, but you should try to match your CLR type as close to the actual data as possible anyway.

matrix = [[1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3]]
    
rows = len(matrix)
cols = len(matrix[0])

transposed = []
while len(transposed) < cols:
    transposed.append([])
    while len(transposed[-1]) < rows:
        transposed[-1].append(0)

for i in range(rows):
    for j in range(cols):
        transposed[j][i] = matrix[i][j]

for i in transposed:
    print(i)

As docs say you have to call setTheme before any view output. It seems that super.onCreate() takes part in view processing.

So, to switch between themes dynamically you simply need to call setTheme before super.onCreate like this:

public void onCreate(Bundle savedInstanceState) {
    setTheme(android.R.style.Theme);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
}

try:

select * from table 1 left join table2 as t on 1 = 1;

This will bring all the columns from both the table.

There are a few options:

Read all sheets directly into an ordered dictionary.

import pandas as pd

# for pandas version >= 0.21.0
sheet_to_df_map = pd.read_excel(file_name, sheet_name=None)

# for pandas version < 0.21.0
sheet_to_df_map = pd.read_excel(file_name, sheetname=None)

Read the first sheet directly into dataframe

df = pd.read_excel('excel_file_path.xls')
# this will read the first sheet into df

Read the excel file and get a list of sheets. Then chose and load the sheets.

xls = pd.ExcelFile('excel_file_path.xls')

# Now you can list all sheets in the file
xls.sheet_names
# ['house', 'house_extra', ...]

# to read just one sheet to dataframe:
df = pd.read_excel(file_name, sheetname="house")

Read all sheets and store it in a dictionary. Same as first but more explicit.

# to read all sheets to a map
sheet_to_df_map = {}
for sheet_name in xls.sheet_names:
    sheet_to_df_map[sheet_name] = xls.parse(sheet_name)
    # you can also use sheet_index [0,1,2..] instead of sheet name.

Thanks @ihightower for pointing it out way to read all sheets and @toto_tico for pointing out the version issue.

sheetname : string, int, mixed list of strings/ints, or None, default 0 Deprecated since version 0.21.0: Use sheet_name instead Source Link

Here is the one-liner version getting the client's IP address:

$ip = @$_SERVER['HTTP_CLIENT_IP'] ?: @$_SERVER['HTTP_X_FORWARDED_FOR'] ?: @$_SERVER['REMOTE_ADDR'];

Notes:

• By using @, it suppresses the PHP notices.

• Value from HTTP_X_FORWARDED_FOR may consist multiple addresses separated by comma, so if you prefer to get the first one, you can use the following method:

  current(explode(',', @$_SERVER['HTTP_X_FORWARDED_FOR']))
  

Simplest way is probably to just use Zend Framework or any of the other frameworks like CakePHP or Symphony.

You can do it with the standard mail function too, but you'll need a bit more knowledge on how to attach pictures.

Alternatively, just host the images on a server instead of attaching them. Sending HTML mail is documented in the mail function documentation.

They have their listeners which has to be used by you by using their library classes in your code. You need not to bother about pushing. You have to send the message to server server will push the message to the device. They use OAuth. Regarding Protocols, there are two methods using CCS and XMPP. CCS just uses XMPP as an authenticated transport layer, so you can use most XMPP libraries to manage the connection. To send notifications to device you can write code in android app to send as well as your server code. the message sending will be done only by your code. Rest will be taken care by Google Server in GCM case. You can check detail at this link

http://developer.android.com/google/gcm/server.html

Also, for security issues

google cloud messaging security https://groups.google.com/forum/#!topic/android-gcm/M-EevBitbhQ

In case your app is not running then also devices can recieve notification because you have to write code for broadcast listeners. In background it will be listening to server and whenever any message packet will be there it will recieve the message as notification. Android has service you need to not to bother about it. You have only to use those resources using the library class that makes your work easier and let them write if your app is not running then also it recieve notification. Obviously, there would be some listener whick make the app to recieve.Check "Recieve the message" section in this link

http://developer.android.com/google/gcm/client.html

It will acccept request from users also. For GCM it will do. Please check "Send a message"

http://developer.android.com/google/gcm/client.html

For Windows Forms applications an optional disabling of a UI-Control can be very useful. So my suggestion looks like this:

public class AppWaitCursor : IDisposable
{
    private readonly Control _eventControl;

    public AppWaitCursor(object eventSender = null)
    {
         _eventControl = eventSender as Control;
        if (_eventControl != null)
            _eventControl.Enabled = false;

        Application.UseWaitCursor = true;
        Application.DoEvents();
    }

    public void Dispose()
    {
        if (_eventControl != null)
            _eventControl.Enabled = true;

        Cursor.Current = Cursors.Default;
        Application.UseWaitCursor = false;
    }
}

Usage:

private void UiControl_Click(object sender, EventArgs e)
{
    using (new AppWaitCursor(sender))
    {
        LongRunningCall();
    }
}

If anyone else comes across this and the accepted answer doesn't work (it didn't for me), check to see if you need to specify a port other than 80. In my case, I was running a rails server at localhost:3000 and was just using curl http://localhost, which was hitting port 80.

Changing the command to curl http://localhost:3000 is what worked in my case.

i used pagewil's print method, and it worked very nicely.

here is my slightly extended version with (sloppy) indents and distinct prop/ob delimiters:

var print = function(obj, delp, delo, ind){
    delp = delp!=null ? delp : "\t"; // property delimeter
    delo = delo!=null ? delo : "\n"; // object delimeter
    ind = ind!=null ? ind : " "; // indent; ind+ind geometric addition not great for deep objects
    var str='';

    for(var prop in obj){
        if(typeof obj[prop] == 'string' || typeof obj[prop] == 'number'){
          var q = typeof obj[prop] == 'string' ? "" : ""; // make this "'" to quote strings
          str += ind + prop + ': ' + q + obj[prop] + q + '; ' + delp;
        }else{
          str += ind + prop + ': {'+ delp + print(obj[prop],delp,delo,ind+ind) + ind + '}' + delo;
        }
    }
    return str;
};

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

Well, I just had the same problem. Even if route had '%' could not connect remotely. Now, having a look at my.ini file (config file in windows) the bind-address statement was missed.

So... I putted this bind-address = * after [mysqld] and restarted the service. Now it works!

All the answers are not really correct, try this:

select * from shirts where 1 IN (colors);

You can set a primary key on a text column. In phpMyAdmin, display the Structure of your table, click on Indexes, then ask to create the index on one column. Then choose PRIMARY, pick your TEXT column, but you have to put a length big enough so that its unique.

You shouldn't be passing anything in to getCountry(). Remove Locale.getDefault():

String locale = context.getResources().getConfiguration().locale.getCountry();

Note: For <a> elements, omit data-target, and use href="#modalID" instead.

An alternative on Linux to using either /proc/self/exe or argv[0] is using the information passed by the ELF interpreter, made available by glibc as such:

#include <stdio.h>
#include <sys/auxv.h>

int main(int argc, char **argv)
{
    printf("%s\n", (char *)getauxval(AT_EXECFN));
    return(0);
}

Note that getauxval is a glibc extension, and to be robust you should check so that it doesn't return NULL (indicating that the ELF interpreter hasn't provided the AT_EXECFN parameter), but I don't think this is ever actually a problem on Linux.

['a','b','c'].flatMap(function(e) {
    return [e, e+ 'x', e+ 'y',  e+ 'z'  ];
});
//['a', 'ax', 'ay', 'az', 'b', 'bx', 'by', 'bz', 'c', 'cx', 'cy', 'cz']


['a','b','c'].map(function(e) {
    return [e, e+ 'x', e+ 'y',  e+ 'z'  ];
});
//[Array[4], Array[4], Array[4]]

You use flatMap when you have an Observable whose results are more Observables.

If you have an observable which is produced by an another observable you can not filter, reduce, or map it directly because you have an Observable not the data. If you produce an observable choose flatMap over map; then you are okay.

As in second snippet, if you are doing async operation you need to use flatMap.

var source = Rx.Observable.interval(100).take(10).map(function(num){_x000D_
    return num+1_x000D_

to make UITableView sections header not sticky or sticky:

1. change the table view's style - make it grouped for not sticky & make it plain for sticky section headers - do not forget: you can do it from storyboard without writing code. (click on your table view and change it is style from the right Side/ component menu)

2. if you have extra components such as custom views or etc. please check the table view's margins to create appropriate design. (such as height of header for sections & height of cell at index path, sections)

To me this is just one of many idiosyncracies (emphasis on the idio(t) ) of typescript that causes people to pull out their hair and curse the developers. Maybe they could work on coming up with more understandable error messages.

It'll have the same behavior as the underlying recv libc call see the man page for an official description of behavior (or read a more general description of the sockets api).

If none of the above worked, try these as well:

• In Component services >Computes >My Computer>Dcom config>Microsoft Excel Application>Properties, go to security tab, click on customize on all three sections and add the user that want to run the application, and give full permissions to the user.

• Go to C:\Windows\Temp make sure it exists and it doesn't prompt you for entering.

Don't double click Project.xcodeproj to start your xcode project. Instead, close your project and open the xcworkspace.

You should also add the missing ones.

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } }); 

Fiddle

Basically you are positioning the cursor before the first row and then requesting data. You need to move the cursor to the first row.

 result.next();
 String foundType = result.getString(1);

It is common to do this in an if statement or loop.

if(result.next()){
   foundType = result.getString(1);
}

I would approach this by using re.match in the following way:

import re
match = re.match(r"([a-z]+)([0-9]+)", 'foofo21', re.I)
if match:
    items = match.groups()
print(items)
>> ("foofo", "21")

Compile constants can only be primitives and Strings:

15.28. Constant Expressions

A compile-time constant expression is an expression denoting a value of primitive type or a String that does not complete abruptly and is composed using only the following:

• Literals of primitive type and literals of type String
• Casts to primitive types and casts to type String
• [...] operators [...]
• Parenthesized expressions whose contained expression is a constant expression.
• Simple names that refer to constant variables.
• Qualified names of the form TypeName . Identifier that refer to constant variables.

Actually in java there is no way to protect items in an array. At runtime someone can always do FieldValues.FIELD1[0]="value3", therefore the array cannot be really constant if we look deeper.

I use strrchr(). For instance to find the extension of a file I use this function:

$string = 'filename.jpg';
$extension = strrchr( $string, '.'); //returns ".jpg"

1. run git rebase -i <sha1 or ref of starting point>

2. mark all commits that you want to change with edit (or e)

3. loop the following two commands until you have processed all the commits:

   git commit --amend --reuse-message=HEAD --author="New Author <[email protected]>" ; git rebase --continue

This will keep all the other commit information (including the dates). The --reuse-message=HEAD option prevents the message editor from launching.

If you should loose your entry point in your Storyboard or simply wish to change the entry point you can specify this in Interface Builder. To set a new entry point you must first decide which ViewController will act as the new entry point and in the Attribute Inspector select the Initial Scene checkbox.

I am updating one news here. Using 'prefs:' only is NOT rejected by Apple, I tested it and checked approved to the app store(in Aug, 2016). thx.

Add .idea and *.iml to .gitignore, you don't need those files to successfully import and compile the project.

[Facepalm] My issue was that I had added the dependency in the C++ way of doing things.

Go to the project that won't build, open up the 'References' folder in Solution Explorer, and see if your dependency is listed.

If not, you can 'Add Reference' and choose the dependency on the Projects tab.

Try this:

<script>
    var myWindow = window.open("ANYURL", "MyWindowName", "width=700,height=700");
    this.window.close();
</script>

This worked for me in some cases in Google Chrome 50. It does not seem to work when put inside a javascript function, though.

Here is another variation that works well for me, adjust the rect.top + 40, rect.left + 0 to suit your needs:

$(".datepicker").datepicker({_x000D_
    changeMonth: true,_x000D_
    changeYear: true,_x000D_
    dateFormat: 'mm/dd/yy',_x000D_
    beforeShow: function (input, inst) {_x000D_
        var rect = input.getBoundingClientRect();_x000D_
        setTimeout(function () {_x000D_
         inst.dpDiv.css({ top: rect.top + 40, left: rect.left + 0 });_x000D_
        }, 0);_x000D_
    }_x000D_
});

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.2/themes/smoothness/jquery-ui.css">_x000D_

Currently your application support 100 connections in pool. Here is what conn string will look like if you want to increase it to 200:

public static string srConnectionString = 
                "server=localhost;database=mydb;uid=sa;pwd=mypw;Max Pool Size=200;";

You can investigate how many connections with database your application use, by executing sp_who procedure in your database. In most cases default connection pool size will be enough.

You are using an adjacent sibling selector (+) when the elements are not siblings. The label is the parent of the input, not it's sibling.

CSS has no way to select an element based on it's descendents (nor anything that follows it).

You'll need to look to JavaScript to solve this.

Alternatively, rearrange your markup:

<input id="foo"><label for="foo">…</label>

This post is high up when you google that error message, which I got when installing security patch KB4505224 on SQL Server 2017 Express i.e. None of the above worked for me, but did consume several hours trying.

The solution for me, partly from here was:

1. uninstall SQL Server
2. in Regional Settings / Management / System Locale, "Beta: UTF-8 support" should be OFF
3. re-install SQL Server
4. Let Windows install the patch.

And all was well.

List of XML and HTML character entity references:

In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference. This article lists the character entity references that are valid in HTML and XML documents.

That article lists the following five predefined XML entities:

quot  "
amp   &
apos  '
lt    <
gt    >

More complete sample from here and here.

Or you can check out my layout sample. p.s no need to put API key in the map view.

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

    <com.google.android.gms.maps.MapView
            android:id="@+id/map_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="2"
            />

    <ListView android:id="@+id/nearby_lv"

              android:layout_height="match_parent"
              android:background="@color/white"
              android:layout_weight="1"
            />

</LinearLayout>

you just need to put this

($('#{{ form.email.id_for_label }}').attr("placeholder","Work email address"));

($('#{{ form.password1.id_for_label }}').attr("placeholder","Password"));

You do not need jQuery to do this...

function sortUnorderedList(ul, sortDescending) {
  if(typeof ul == "string")
    ul = document.getElementById(ul);

  // Idiot-proof, remove if you want
  if(!ul) {
    alert("The UL object is null!");
    return;
  }

  // Get the list items and setup an array for sorting
  var lis = ul.getElementsByTagName("LI");
  var vals = [];

  // Populate the array
  for(var i = 0, l = lis.length; i < l; i++)
    vals.push(lis[i].innerHTML);

  // Sort it
  vals.sort();

  // Sometimes you gotta DESC
  if(sortDescending)
    vals.reverse();

  // Change the list on the page
  for(var i = 0, l = lis.length; i < l; i++)
    lis[i].innerHTML = vals[i];
}

Easy to use...

sortUnorderedList("ID_OF_LIST");

I am using this method to avoid the popup blocker in my React code. it will work in all other javascript codes also.

When you are making an async call on click event, just open a blank window first and then write the URL in that later when an async call will complete.

const popupWindow = window.open("", "_blank");
popupWindow.document.write("<div>Loading, Plesae wait...</div>")

on async call's success, write the following

popupWindow.document.write(resonse.url)

You're nesting mocking inside of mocking. You're calling getSomeList(), which does some mocking, before you've finished the mocking for MyMainModel. Mockito doesn't like it when you do this.

Replace

@Test
public myTest(){
    MyMainModel mainModel =  Mockito.mock(MyMainModel.class);
    Mockito.when(mainModel.getList()).thenReturn(getSomeList()); --> Line 355
}

with

@Test
public myTest(){
    MyMainModel mainModel =  Mockito.mock(MyMainModel.class);
    List<SomeModel> someModelList = getSomeList();
    Mockito.when(mainModel.getList()).thenReturn(someModelList);
}

To understand why this causes a problem, you need to know a little about how Mockito works, and also be aware in what order expressions and statements are evaluated in Java.

Mockito can't read your source code, so in order to figure out what you are asking it to do, it relies a lot on static state. When you call a method on a mock object, Mockito records the details of the call in an internal list of invocations. The when method reads the last of these invocations off the list and records this invocation in the OngoingStubbing object it returns.

The line

Mockito.when(mainModel.getList()).thenReturn(someModelList);

causes the following interactions with Mockito:

• Mock method mainModel.getList() is called,
• Static method when is called,
• Method thenReturn is called on the OngoingStubbing object returned by the when method.

The thenReturn method can then instruct the mock it received via the OngoingStubbing method to handle any suitable call to the getList method to return someModelList.

In fact, as Mockito can't see your code, you can also write your mocking as follows:

mainModel.getList();
Mockito.when((List<SomeModel>)null).thenReturn(someModelList);

This style is somewhat less clear to read, especially since in this case the null has to be casted, but it generates the same sequence of interactions with Mockito and will achieve the same result as the line above.

However, the line

Mockito.when(mainModel.getList()).thenReturn(getSomeList());

causes the following interactions with Mockito:

1. Mock method mainModel.getList() is called,
2. Static method when is called,
3. A new mock of SomeModel is created (inside getSomeList()),
4. Mock method model.getName() is called,

At this point Mockito gets confused. It thought you were mocking mainModel.getList(), but now you're telling it you want to mock the model.getName() method. To Mockito, it looks like you're doing the following:

when(mainModel.getList());
// ...
when(model.getName()).thenReturn(...);

This looks silly to Mockito as it can't be sure what you're doing with mainModel.getList().

Note that we did not get to the thenReturn method call, as the JVM needs to evaluate the parameters to this method before it can call the method. In this case, this means calling the getSomeList() method.

Generally it is a bad design decision to rely on static state, as Mockito does, because it can lead to cases where the Principle of Least Astonishment is violated. However, Mockito's design does make for clear and expressive mocking, even if it leads to astonishment sometimes.

Finally, recent versions of Mockito add an extra line to the error message above. This extra line indicates you may be in the same situation as this question:

3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed

I have gone through array of solutions and this is what I found to have worked great for me.

In my case I needed to send a post request with some credentials. Small overhead was to add jquery inside the script. But was worth it.

var printPDF = function () {
        //prevent double sending
        var sendz = {};
        sendz.action = "Print";
        sendz.url = "api/Print";
        jQuery('<form action="' + sendz.url + '" method="POST">' +
            '<input type="hidden" name="action" value="Print" />'+
            '<input type="hidden" name="userID" value="'+$scope.user.userID+'" />'+
            '<input type="hidden" name="ApiKey" value="' + $scope.user.ApiKey+'" />'+
            '</form>').appendTo('body').submit().remove();

    }

I would use it-str.begin() In this particular case std::distance and operator- are the same. But if container will change to something without random access, std::distance will increment first argument until it reach second, giving thus linear time and operator- will not compile. Personally I prefer the second behaviour - it's better to be notified when you algorithm from O(n) became O(n^2)...

At my work we have our restful services on a different port number and the data resides in db2 on a pair of AS400s. We typically use the $.getJSON AJAX method because it easily returns JSONP using the ?callback=? without having any issues with CORS.

data ='USER=<?echo trim($USER)?>' +
         '&QRYTYPE=' + $("input[name=QRYTYPE]:checked").val();

        //Call the REST program/method returns: JSONP 
        $.getJSON( "http://www.stackoverflow.com/rest/resttest?callback=?",data)
        .done(function( json ) {        

              //  loading...
                if ($.trim(json.ERROR) != '') {
                    $("#error-msg").text(message).show();
                }
                else{
                    $(".error").hide();
                    $("#jsonp").text(json.whatever);

                }

        })  
        .fail(function( jqXHR, textStatus, error ) {
        var err = textStatus + ", " + error;
        alert('Unable to Connect to Server.\n Try again Later.\n Request Failed: ' + err);
        });     

Please be careful, MSSQL: "SELECT * INTO NewTable FROM OldTable"

is not always the same as MYSQL: "create table temp AS select.."

I think that there are occasions when this (in MSSQL) does not guarantee that all the fields in the new table are of the same type as the old.

For example :

create table oldTable (field1 varchar(10), field2 integer, field3 float)
insert into oldTable (field1,field2,field3) values ('1', 1, 1)
select top 1 * into newTable from oldTable

does not always yield:

create table newTable (field1 varchar(10), field2 integer, field3 float)

but may be:

create table newTable (field1 varchar(10), field2 integer, field3 integer)

In Angular 7 the for loop is like below

var values = [
        {
            "name":"Thomas",
            "password":"thomas"
        },
        { 
            "name":"linda",
            "password":"linda"
        }];

for (let item of values)
{
}

Request.ServerVariables["REMOTE_ADDR"] should work - either directly in a view or in the controller action method body (Request is a property of Controller class in MVC, not Page).

It is working.. but you have to publish on a real IIS not the virtual one.

The one below works for me every time..

This site also has a few other suggestions, but this no-nonsense, no-worry one is available in a github:gist and answers your question (pasted here for convenience):

function hideAddressBar()
{
  if(!window.location.hash)
  {
      if(document.height < window.outerHeight)
      {
          document.body.style.height = (window.outerHeight + 50) + 'px';
      }

      setTimeout( function(){ window.scrollTo(0, 1); }, 50 );
  }
}

window.addEventListener("load", function(){ if(!window.pageYOffset){ hideAddressBar(); } } );
window.addEventListener("orientationchange", hideAddressBar );

As far as I can tell, the combination of extra height added to the page (which caused problems for you) and the scrollTo() statement make the address bar disappear.

From the same site the 'simplest' solution to hiding the address bar is using the scrollTo() method:

window.addEventListener("load", function() { window.scrollTo(0, 1); });

This will hide the address bar until the user scrolls.

This site places the same method inside a timeout function (the justification is not explained, but it claims the code doesn't work well without it):

// When ready...
window.addEventListener("load",function() {
  // Set a timeout...
  setTimeout(function(){
    // Hide the address bar!
     window.scrollTo(0, 1);
  }, 0);
});

In my case, I was getting this error thrown due to the necessary dependent system resources not being installed.

More specifically, I have a NodeJS app that is utilizing ImageMagick. Despite having the npm package installed, the core Linux ImageMagick was not installed. I did an apt-get to install ImageMagick and after that all worked great!

Here is a solution using functions plot(), polygon() and lines().

 set.seed(1234)
 df <- data.frame(x =1:10,
                 F =runif(10,1,2),
                 L =runif(10,0,1),
                 U =runif(10,2,3))


 plot(df$x, df$F, ylim = c(0,4), type = "l")
 #make polygon where coordinates start with lower limit and 
 # then upper limit in reverse order
 polygon(c(df$x,rev(df$x)),c(df$L,rev(df$U)),col = "grey75", border = FALSE)
 lines(df$x, df$F, lwd = 2)
 #add red lines on borders of polygon
 lines(df$x, df$U, col="red",lty=2)
 lines(df$x, df$L, col="red",lty=2)

Now use example data provided by OP in another question:

I have a table which has about 120,000 records and need to select only those which does not exist (matched with a varchar column) in four other tables with number of rows approx 1500, 4000, 40000, 200. All the involved tables have unique index on the concerned Varchar column.

NOT IN took about 10 mins, NOT EXISTS took 4 secs.

I have a recursive query which might had some untuned section which might have contributed to the 10 mins, but the other option taking 4 secs explains, atleast to me that NOT EXISTS is far better or at least that IN and EXISTS are not exactly the same and always worth a check before going ahead with code.

I do prefer aliases, and for things that might need multiple commands, based on your project needs, I prefer functions...

Example

function switchGCPProject() {
        gcloud config set project [Project Name]
        // if you are using GKE use the following
        gcloud config set container/cluster [Cluster Name]
        // if you are using GCE use the following
        gcloud config set compute/zone [Zone]
        gcloud config set compute/region [region]
        // if you are using GKE use the following
        gcloud container clusters get-credentials [cluster name] --zone [Zone] --project [project name]
        export GOOGLE_APPLICATION_CREDENTIALS=path-to-credentials.json
}

As Unwind points out f and g provide different default outputs.

Roughly speaking if you care more about the details of what comes after the decimal point I would do with f and if you want to scale for large numbers go with g. From some dusty memories f is very nice with small values if your printing tables of numbers as everything stays lined up but something like g is needed if you stand a change of your numbers getting large and your layout matters. e is more useful when your numbers tend to be very small or very large but never near ten.

An alternative is to specify the output format so that you get the same number of characters representing your number every time.

Sorry for the woolly answer but it is a subjective out put thing that only gets hard answers if the number of characters generated is important or the precision of the represented value.

Solutions suggested above will work only if data is aligned..
See solution in the link using PythonScript Notepad++ plugin, It Works great!

If you do not have an LDF file then:

1) put the MDF in the C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\

2) In ssms, go to Databases -> Attach and add the MDF file. It will not let you add it this way but it will tell you the database name contained within.

3) Make sure the user you are running ssms.exe as has acccess to this MDF file.

4) Now that you know the DbName, run

EXEC sp_attach_single_file_db @dbname = 'DbName', 
@physname = N'C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\yourfile.mdf';

Based on Brian Digg's post, here are two helpful functions for filtering lists:

#Returns all items in a list that are not contained in toMatch
#toMatch can be a single item or a list of items
exclude <- function (theList, toMatch){
  return(setdiff(theList,include(theList,toMatch)))
}

#Returns all items in a list that ARE contained in toMatch
#toMatch can be a single item or a list of items
include <- function (theList, toMatch){
  matches <- unique (grep(paste(toMatch,collapse="|"), 
                          theList, value=TRUE))
  return(matches)
}

Please never do this in real projects:

document.getElementById("span").innerHTML = "String".fontsize(25);

<span id="span"></span>

I wanted to share how you can use this to change a attribute of the button, because it took me some time to figure it out...

For example in order to change it's background to yellow:

$("#"+String(this.id)).css("background-color","yellow");

Easy way out is to use a condition like this ( use desired date > GETDATE()-1)

your sql statement "date specific" > GETDATE()-1

A Media Query inside of an iframe can function as an element query. I've successfully implement this. The idea came from a recent post about Responsive Ads by Zurb. No Javascript!

As a variation of @tangens answer: if you can't wait for the garbage collector to clean up your thread, cancel the timer at the end of your run method.

Timer t = new java.util.Timer();
t.schedule( 
        new java.util.TimerTask() {
            @Override
            public void run() {
                // your code here
                // close the thread
                t.cancel();
            }
        }, 
        5000 
);

public static ArtworkData[] GetDataRecords(int UsersID)
{
    ArtworkData[] Labels;
    Labels = new ArtworkData[3];

    return Labels;
}

This should work.

You only use the brackets when creating an array or accessing an array. Also, Array[] is returning an array of array. You need to return the typed array ArtworkData[].

1. Move the cursor to the n in name.
2. Enter visual block mode (Ctrlv).
3. Press j three times (or 3j).
4. Press I (capital i).
5. Type in vendor_. Note: It will only update the screen in the first line - until Esc is pressed (6.), at which point all lines will be updated.
6. Press Esc.

An uppercase I must be used rather than a lowercase i, because the lowercase i is interpreted as the start of a text object, which is rather useful on its own, e.g. for selecting inside a tag block (it):

Just do it in HTML

<a href="https://www.google.com">Google</a>

I'm not sure if you can alter the original element but how about switch from using the id attr to something else like data-id? Then just read the value of data-id for your hash value and it won't jump.

If I understood well (not sure) you want to print using <CR> and not <LR>?

If so this is possible, as long the console terminal allows this (it will break when output si redirected to a file).

from __future__ import print_function
print("count x\r", file=sys.stdout, end=" ")

If you're interested in making .xlsx (Office 2007 and beyond) files, you're in luck. Office 2007+ uses OpenXML which for lack of a more apt description is XML files inside of a zip named .xlsx

Take an excel file (2007+) and rename it to .zip, you can open it up and take a look. If you're using .NET 3.5 you can use the System.IO.Packaging library to manipulate the relationships & zipfile itself, and linq to xml to play with the xml (or just DOM if you're more comfortable).

Otherwise id reccomend DotNetZip, a powerfull library for manipulation of zipfiles.

OpenXMLDeveloper has lots of resources about OpenXML and you can find more there.

If you want .xls (2003 and below) you're going to have to look into 3rd party libraries or perhaps learn the file format yourself to achieve this without excel installed.

Pattern are always preferable for restriction, try oninput and min occur 1 for inputting only numbers from 1 onwards

<input type="text" min="1" oninput="this.value=this.value.replace(/[^0-9]/g,'');"
                                value=${var} >

This is covered in section 7.4.1 of the C# language spec. Only a variable-reference can be passed as a ref or out parameter in an argument list. A property does not qualify as a variable reference and hence cannot be used.

PowerShell has really wacky return semantics - at least when viewed from a more traditional programming perspective. There are two main ideas to wrap your head around:

• All output is captured, and returned
• The return keyword really just indicates a logical exit point

Thus, the following two script blocks will do effectively the exact same thing:

$a = "Hello, World"
return $a

$a = "Hello, World"
$a
return

The $a variable in the second example is left as output on the pipeline and, as mentioned, all output is returned. In fact, in the second example you could omit the return entirely and you would get the same behavior (the return would be implied as the function naturally completes and exits).

Without more of your function definition I can't say why you are getting a PSMethod object. My guess is that you probably have something a few lines up that is not being captured and is being placed on the output pipeline.

It is also worth noting that you probably don't need those semicolons - unless you are nesting multiple expressions on a single line.

You can read more about the return semantics on the about_Return page on TechNet, or by invoking the help return command from PowerShell itself.

If you don't want to use float, the easiest and cleanest way to do it is by using an auto width column:

<div class="row">
  <div class="col">
    <h3 class="one">Text</h3>
  </div>
  <div class="col-auto">
    <button class="btn btn-secondary pull-right">Button</button>
  </div>
</div>

After reading everyone's comments (thank you for your interest), I found that the "best" way (least amount of code, best performing) to do this was to simply sort the Array, and then grab the first value in the Array:

var myArray:Array /* of Number */ = [2,3,3,4,2,2,5,6,7,2];

myArray.sort(Array.NUMERIC);

var minValue:int = myArray[0];

This also works for an Array of Objects - you simply use the Array.sortOn() function and specify a property:

// Sample data
var myArray:Array /* of XML */ = 
    [
    <item level="2" name="a" />
    <item level="3" name="b" />
    <item level="3" name="c" />
    <item level="2" name="d" />
    <item level="5" name="e" />
    ]

// Perform a descending sort on the specified attribute in Array to get the maximum value
myArray.sortOn("@level", Array.DESCENDING | Array.NUMERIC);

var lowestLevel:int = myArray[0].@level;

I hope this helps someone else someday!

Here is a brief pointer on void pointers: https://www.learncpp.com/cpp-tutorial/613-void-pointers/

6.13 — Void pointers

Because the void pointer does not know what type of object it is pointing to, it cannot be dereferenced directly! Rather, the void pointer must first be explicitly cast to another pointer type before it is dereferenced.

If a void pointer doesn't know what it's pointing to, how do we know what to cast it to? Ultimately, that is up to you to keep track of.

Void pointer miscellany

It is not possible to do pointer arithmetic on a void pointer. This is because pointer arithmetic requires the pointer to know what size object it is pointing to, so it can increment or decrement the pointer appropriately.

Assuming the machine's memory is byte-addressable and does not require aligned accesses, the most generic and atomic (closest to the machine level representation) way of interpreting a void* is as a pointer-to-a-byte, uint8_t*. Casting a void* to a uint8_t* would allow you to, for example, print out the first 1/2/4/8/however-many-you-desire bytes starting at that address, but you can't do much else.

uint8_t* byte_p = (uint8_t*)p;
for (uint8_t* i = byte_p; i < byte_p + 8; i++) {
  printf("%x ",*i);
}

The following command worked for me using the command prompt (As an Administrator) in Windows:

mysqlcheck -u root -p -A --auto-repair

Run mysqlcheck with the root user, prompt for a password, check all databases, and auto-repair any corrupted tables.

View Model is class which we can use for rendering data on View. Suppose you have two entities Place and PlaceCategory and you want to access data from both entities using a single model then we use ViewModel.

  public class Place
    {
       public int PlaceId { get; set; }
        public string PlaceName { get; set; }
        public string Latitude { get; set; }
        public string Longitude { get; set; }
        public string BestTime { get; set; }
    }
    public class Category
    {
        public int ID { get; set; }
        public int? PlaceId { get; set; }
        public string PlaceCategoryName { get; set; }
        public string PlaceCategoryType { get; set; }
    }
    public class PlaceCategoryviewModel
    {
        public string PlaceName { get; set; }
        public string BestTime { get; set; }
        public string PlaceCategoryName { get; set; }
        public string PlaceCategoryType { get; set; }
    }

So in above Example Place and Category are the two different entities and PlaceCategory viewmodel is ViewModel which we can use on View.

Am adding this answer for the purpose of those who google about this..

There was an episode of DevBytes (ListView Cell Dragging and Rearranging) recently which explains how to do this

You can find it here also the sample code is available here.

What this code basically does is that it creates a dynamic listview by the extension of listview that supports cell dragging and swapping. So that you can use the DynamicListView instead of your basic ListView and that's it you have implemented a ListView with Drag and Drop.

Not really, because as you say, the compiler only knows that callFriend() is returning an Animal, not a Dog or Duck.

Can you not add an abstract makeNoise() method to Animal that would be implemented as a bark or quack by its subclasses?

Use the backslash \ or choose a different delimiter, ie m#.\d# instead of /.\d/ "In Perl, you can change the / regular expression delimiter to almost any other special character if you preceed it with the letter m (for match);"

<meta property="og:title" content="Ali Umair"/>
<meta property="og:description" content="Ali UMair is a web developer"/><meta property="og:image" content="../image" />

<a target="_blank" href="https://plus.google.com/share?url=<? echo urlencode('http://www..'); ?>"><img src="../gplus-black_icon.png" alt="" /></a>

this code will work with image text and description please put meta into head tag

The reason why your full-width-div doesn't stretch 100% to your screen it's because of its parent "container" which occupies only about 80% of the screen.

If you want to make it stretch 100% to the screen either you make the "full-width-div" position fixed or use the "container-fluid" class instead of "container".

see Bootstrap 3 docs: http://getbootstrap.com/css/#grid

Run following command in git bash that works fine for me

git config --global http.sslverify "false"

$(document).ready(function() {
  $('#div_one').bind('click', function() {
    $('#div_two').addClass('large');
  });
});

If I understood your question.

Or you can modify css directly:

var $speech = $('div.speech');
var currentSize = $speech.css('fontSize');
$speech.css('fontSize', '10px');

Try this

DateTime dDate;
dDate = DateTime.TryParse(inputString);
String.Format("{0:d/MM/yyyy}", dDate);

Why not just extend the Android CheckBox to have better padding instead. That way instead of having to fix it in code every time you use the CheckBox you can just use the fixed CheckBox instead.

First Extend CheckBox:

package com.whatever;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.CheckBox;

/**
 * This extends the Android CheckBox to add some more padding so the text is not on top of the
 * CheckBox.
 */
public class CheckBoxWithPaddingFix extends CheckBox {

    public CheckBoxWithPaddingFix(Context context) {
        super(context);
    }

    public CheckBoxWithPaddingFix(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public CheckBoxWithPaddingFix(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public int getCompoundPaddingLeft() {
        final float scale = this.getResources().getDisplayMetrics().density;
        return (super.getCompoundPaddingLeft() + (int) (10.0f * scale + 0.5f));
    }
}

Second in your xml instead of creating a normal CheckBox create your extended one

<com.whatever.CheckBoxWithPaddingFix
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello there" />

ES6 solution:

import DefaultImage from '../assets/image.png';

const DEFAULT_IMAGE = Image.resolveAssetSource(DefaultImage).uri;

and then:

<Image source={{uri: DEFAULT_IMAGE}} />

Android studio provide all you need to see console.log and other. In logcat just filter to "/Web Console" and you will see your js logs...

If you get any issue you can add this plugin : https://github.com/apache/cordova-plugin-console

First, this is the directory layout that I am using:

.
+-- include
¦   +-- class1.hpp
¦   +-- ...
¦   +-- class2.hpp
+-- src
    +-- class1.cpp
    +-- ...
    +-- class2.cpp

After a couple of days taking a look into this, this is my favourite way of doing this thanks to modern CMake:

cmake_minimum_required(VERSION 3.5)
project(mylib VERSION 1.0.0 LANGUAGES CXX)

set(DEFAULT_BUILD_TYPE "Release")

if(NOT CMAKE_BUILD_TYPE AND NOT CMAKE_CONFIGURATION_TYPES)
  message(STATUS "Setting build type to '${DEFAULT_BUILD_TYPE}' as none was specified.")
  set(CMAKE_BUILD_TYPE "${DEFAULT_BUILD_TYPE}" CACHE STRING "Choose the type of build." FORCE)
  # Set the possible values of build type for cmake-gui
  set_property(CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS "Debug" "Release" "MinSizeRel" "RelWithDebInfo")
endif()

include(GNUInstallDirs)

set(SOURCE_FILES src/class1.cpp src/class2.cpp)

add_library(${PROJECT_NAME} ...)

target_include_directories(${PROJECT_NAME} PUBLIC
    $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
    $<INSTALL_INTERFACE:include>
    PRIVATE src)

set_target_properties(${PROJECT_NAME} PROPERTIES
    VERSION ${PROJECT_VERSION}
    SOVERSION 1)

install(TARGETS ${PROJECT_NAME} EXPORT MyLibConfig
    ARCHIVE  DESTINATION ${CMAKE_INSTALL_LIBDIR}
    LIBRARY  DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME  DESTINATION ${CMAKE_INSTALL_BINDIR})
install(DIRECTORY include/ DESTINATION ${CMAKE_INSTALL_INCLUDEDIR}/${PROJECT_NAME})

install(EXPORT MyLibConfig DESTINATION share/MyLib/cmake)

export(TARGETS ${PROJECT_NAME} FILE MyLibConfig.cmake)

After running CMake and installing the library, there is no need to use Find***.cmake files, it can be used like this:

find_package(MyLib REQUIRED)

#No need to perform include_directories(...)
target_link_libraries(${TARGET} mylib)

That's it, if it has been installed in a standard directory it will be found and there is no need to do anything else. If it has been installed in a non-standard path, it is also easy, just tell CMake where to find MyLibConfig.cmake using:

cmake -DMyLib_DIR=/non/standard/install/path ..

I hope this helps everybody as much as it has helped me. Old ways of doing this were quite cumbersome.

All strings meant for humans should use u"".

I found that the following mindset helps a lot when dealing with Python strings: All Python manifest strings should use the u"" syntax. The "" syntax is for byte arrays, only.

Before the bashing begins, let me explain. Most Python programs start out with using "" for strings. But then they need to support documentation off the Internet, so they start using "".decode and all of a sudden they are getting exceptions everywhere about decoding this and that - all because of the use of "" for strings. In this case, Unicode does act like a virus and will wreak havoc.

But, if you follow my rule, you won't have this infection (because you will already be infected).

Just supply literal values in the SELECT:

INSERT INTO TABLE1 (id, col_1, col_2, col_3)
SELECT id, 'data1', 'data2', 'data3'
FROM TABLE2
WHERE col_a = 'something';

A select list can contain any value expression:

But the expressions in the select list do not have to reference any columns in the table expression of the FROM clause; they can be constant arithmetic expressions, for instance.

And a string literal is certainly a value expression.

Ok, here is a fetch DELETE example too:

fetch('https://example.com/delete-item/' + id, {
  method: 'DELETE',
})
.then(res => res.text()) // or res.json()
.then(res => console.log(res))

Assuming the rectangle is represented by three points A,B,C, with AB and BC perpendicular, you only need to check the projections of the query point M on AB and BC:

0 <= dot(AB,AM) <= dot(AB,AB) &&
0 <= dot(BC,BM) <= dot(BC,BC)

AB is vector AB, with coordinates (Bx-Ax,By-Ay), and dot(U,V) is the dot product of vectors U and V: Ux*Vx+Uy*Vy.

Update. Let's take an example to illustrate this: A(5,0) B(0,2) C(1,5) and D(6,3). From the point coordinates, we get AB=(-5,2), BC=(1,3), dot(AB,AB)=29, dot(BC,BC)=10.

For query point M(4,2), we have AM=(-1,2), BM=(4,0), dot(AB,AM)=9, dot(BC,BM)=4. M is inside the rectangle.

For query point P(6,1), we have AP=(1,1), BP=(6,-1), dot(AB,AP)=-3, dot(BC,BP)=3. P is not inside the rectangle, because its projection on side AB is not inside segment AB.

simply execute -

git stash

it will remove all your local changes. and you can also use it later by executing -

git stash apply 

The more general extension of ViewPager would be to create a SetPagingEnabled method so that we can enable and disable paging on the fly. To enable / disable the swiping, just overide two methods: onTouchEvent and onInterceptTouchEvent. Both will return "false" if the paging was disabled.

public class CustomViewPager extends ViewPager {

    private boolean enabled;

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.enabled = true;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onTouchEvent(event);
        }

        return false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onInterceptTouchEvent(event);
        }

        return false;
    }

    public void setPagingEnabled(boolean enabled) {
        this.enabled = enabled;
    } 
}

Then select this instead of the built-in viewpager in XML

<mypackage.CustomViewPager 
    android:id="@+id/myViewPager" 
    android:layout_height="match_parent" 
    android:layout_width="match_parent" />

You just need to call the setPagingEnabled method with false and users won't be able to swipe to paginate.

You have to explicitly set the position of the parent container along with the position of the child container. The typical way to do that is something like this:

div.parent{
    position: relative;
    left: 0px;  /* stick it wherever it was positioned by default */
    top: 0px;
}

div.child{
    position: absolute;
    left: 10px;
    top: 10px;
}

The file you give is a shell script, not an awk program. So, try sh my.awk.

If you want to use awk -f my.awk life.csv > life_out.cs, then remove awk -F , ' and the last line from the file and add FS="," in BEGIN.

Few other points which might be helpful to understand differences between local and session storage

1. Both local storage and session storage are scoped to document origin, so

   https://mydomain.com/
   http://mydomain.com/
   https://mydomain.com:8080/

   All of the above URL's will not share the same storage. (Notice path of the web page does not affect the web storage)

2. Session storage is different even for the document with same origin policy open in different tabs, so same web page open in two different tabs cannot share the same session storage.

3. Both local and session storage are also scoped by browser vendors. So storage data saved by IE cannot be read by Chrome or FF.

Hope this helps.

Starting from Python 3.3 this becomes super easy with the datetime.timestamp() method. This of course will only be useful if you need the number of seconds from 1970-01-01 UTC.

from datetime import datetime
dt = datetime.today()  # Get timezone naive now
seconds = dt.timestamp()

The return value will be a float representing even fractions of a second. If the datetime is timezone naive (as in the example above), it will be assumed that the datetime object represents the local time, i.e. It will be the number of seconds from current time at your location to 1970-01-01 UTC.

This error occures when you try to refer to a null object instance. I can`t tell you what causes this error by your given information, but you can debug it easily in your IDE. I strongly recommend you that use exception handling to avoid unexpected program behavior.

Using list comprehensions is a pretty obvious one for me. Not sure about performance, but at least things stay lists.

[x for x in a if x in b]

Or "all the x values that are in A, if the X value is in B".

You'd use the corresponding method getVisibility(). Method names prefixed with 'get' and 'set' are Java's convention for representing properties. Some language have actual language constructs for properties but Java isn't one of them. So when you see something labeled 'setX', you can be 99% certain there's a corresponding 'getX' that will tell you the value.

int ArraySize = 400;

int[] terms = new int[ArraySize];


for(int runs = 0; runs < ArraySize; runs++)
{

    terms[runs] = runs;

}

That would be how I'd code it.

Both codes are working fine with me on python 3.7..... hope will work for u as well

import tkinter as tk
m=tk.Tk()
m.iconbitmap("myfavicon.ico")
m.title("SALAH Tutorials")
m.mainloop()

and do not forget to keep "myfavicon.ico" in the same folder where your project script file is present

Another method

from tkinter import *
m=Tk()
m.iconbitmap("myfavicon.ico")
m.title("SALAH Tutorials")
m.mainloop()

[*NOTE:- python version-3 works with tkinter and below version-3 i.e version-2 works with Tkinter]

You are calling GridView.RenderControl(htmlTextWriter), hence the page raises an exception that a Server-Control was rendered outside of a Form.

You could avoid this execption by overriding VerifyRenderingInServerForm

public override void VerifyRenderingInServerForm(Control control)
{
  /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
     server control at run time. */
}

See here and here.

CSS was designed to affect presentation, not behaviour.

You could use some JavaScript.

document.links[0].onclick = function(event) {
   event.preventDefault();
};
