Try this:

rows = int(input('Enter rows\n'))
my_list = []
for i in range(rows):
    my_list.append(list(map(int, input().split())))

it's much easier than you think to write your own, just use an interface for JsonElementInterface with a method string toJson(), and an abstract class AbstractJsonElement implementing that interface,

then all you have to do is have a class for JSONProperty that implements the interface, and JSONValue(any token), JSONArray ([...]), and JSONObject ({...}) that extend the abstract class

JSONObject has a list of JSONProperty's
JSONArray has a list of AbstractJsonElement's

your add function in each should take a vararg list of that type, and return this

now if you don't like something you can just tweak it

the benifit of the inteface and the abstract class is that JSONArray can't accept properties, but JSONProperty can accept objects or arrays

As I replied to "Is there a simple, consistent way to change the color scheme of Eclipse editors?":

I've been looking for this too and after a bit of research found a workable solution. This is based on the FDT editor for Eclipse, but I'm sure you could apply the same logic to other editors.

My blog post: Howto create a color-scheme for FDT

Hope this helps!

The tools sed or tr will do this for you by swapping the whitespace for nothing

sed 's/ //g'

tr -d ' '

Example:

$ echo "   3918912k " | sed 's/ //g'
3918912k

please modify your router.module.ts as:

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [
        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree',
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        },
        {
           path: '',
           redirectTo: 'two',
           pathMatch: 'full'
        }
    ]
},];

and in your component1.html

<h3>In One</h3>

<nav>
    <a routerLink="/two" class="dash-item">...Go to Two...</a>
    <a routerLink="/two/three" class="dash-item">... Go to THREE...</a>
    <a routerLink="/two/four" class="dash-item">...Go to FOUR...</a>
</nav>

<router-outlet></router-outlet>                   // Successfully loaded component2.html
<router-outlet name="nameThree" ></router-outlet> // Error: Cannot match any routes. URL Segment: 'three'
<router-outlet name="nameFour" ></router-outlet>  // Error: Cannot match any routes. URL Segment: 'three'

If you're using jQuery then there are a few different ways to set the disabled attribute.

var $element = $(...);
    $element.prop('disabled', true);
    $element.attr('disabled', true); 

    // The following do not require jQuery
    $element.get(0).disabled = true;
    $element.get(0).setAttribute('disabled', true);
    $element[0].disabled = true;
    $element[0].setAttribute('disabled', true);

As others have already said, parameters passed through the command line can be accessed in batch files with the notation %1 to %9. There are also two other tokens that you can use:

• %0 is the executable (batch file) name as specified in the command line.
• %* is all parameters specified in the command line -- this is very useful if you want to forward the parameters to another program.

There are also lots of important techniques to be aware of in addition to simply how to access the parameters.

Checking if a parameter was passed

This is done with constructs like IF "%~1"=="", which is true if and only if no arguments were passed at all. Note the tilde character which causes any surrounding quotes to be removed from the value of %1; without a tilde you will get unexpected results if that value includes double quotes, including the possibility of syntax errors.

Handling more than 9 arguments (or just making life easier)

If you need to access more than 9 arguments you have to use the command SHIFT. This command shifts the values of all arguments one place, so that %0 takes the value of %1, %1 takes the value of %2, etc. %9 takes the value of the tenth argument (if one is present), which was not available through any variable before calling SHIFT (enter command SHIFT /? for more options).

SHIFT is also useful when you want to easily process parameters without requiring that they are presented in a specific order. For example, a script may recognize the flags -a and -b in any order. A good way to parse the command line in such cases is

:parse
IF "%~1"=="" GOTO endparse
IF "%~1"=="-a" REM do something
IF "%~1"=="-b" REM do something else
SHIFT
GOTO parse
:endparse
REM ready for action!

This scheme allows you to parse pretty complex command lines without going insane.

Substitution of batch parameters

For parameters that represent file names the shell provides lots of functionality related to working with files that is not accessible in any other way. This functionality is accessed with constructs that begin with %~.

For example, to get the size of the file passed in as an argument use

ECHO %~z1

To get the path of the directory where the batch file was launched from (very useful!) you can use

ECHO %~dp0

You can view the full range of these capabilities by typing CALL /? in the command prompt.

The query below will give you a list of all users and their permissions on the table in a schema.

select a.schemaname, a.tablename, b.usename,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'select') as has_select,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'insert') as has_insert,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'update') as has_update,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'delete') as has_delete, 
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'references') as has_references 
from pg_tables a, pg_user b 
where a.schemaname = 'your_schema_name' and a.tablename='your_table_name';

More details on has_table_privilages can be found here.

Yes, you are correct. If you are using a jQuery plugin, do not put the code in the controller. Instead create a directive and put the code that you would normally have inside the link function of the directive.

There are a couple of points in the documentation that you could take a look at. You can find them here:
Common Pitfalls

Using controllers correctly

Ensure that when you are referencing the script in your view, you refer it last - after the angularjs library, controllers, services and filters are referenced.

EDIT: Rather than using $(element), you can make use of angular.element(element) when using AngularJS with jQuery

For the <input> element there's the maxlength attribute:

<input type="text" id="Textbox" name="Textbox" maxlength="10" />

(by the way, the type is "text", not "textbox" as others are writing), however, you have to use javascript with <textarea>s. Either way the length should be checked on the server anyway.

Knowing how to write a preset dictionary is useful to know as well:

cmap =  {'US':'USA','GB':'Great Britain'}

# Explicitly:
# -----------
def cxlate(country):
    try:
        ret = cmap[country]
    except KeyError:
        ret = '?'
    return ret

present = 'US' # this one is in the dict
missing = 'RU' # this one is not

print cxlate(present) # == USA
print cxlate(missing) # == ?

# or, much more simply as suggested below:

print cmap.get(present,'?') # == USA
print cmap.get(missing,'?') # == ?

# with country codes, you might prefer to return the original on failure:

print cmap.get(present,present) # == USA
print cmap.get(missing,missing) # == RU

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

The CSS table model is based on the HTML table model http://www.w3.org/TR/CSS21/tables.html

A table is divided into ROWS, and each row contains one or more cells. Cells are children of ROWS, they are NEVER children of columns.

"display: table-column" does NOT provide a mechanism for making columnar layouts (e.g. newspaper pages with multiple columns, where content can flow from one column to the next).

Rather, "table-column" ONLY sets attributes that apply to corresponding cells within the rows of a table. E.g. "The background color of the first cell in each row is green" can be described.

The table itself is always structured the same way it is in HTML.

In HTML (observe that "td"s are inside "tr"s, NOT inside "col"s):

<table ..>
  <col .. />
  <col .. />
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
</table>

Corresponding HTML using CSS table properties (Note that the "column" divs do not contain any contents -- the standard does not allow for contents directly in columns):

.mytable {_x000D_
  display: table;_x000D_
}_x000D_
.myrow {_x000D_
  display: table-row;_x000D_
}_x000D_
.mycell {_x000D_
  display: table-cell;_x000D_
}_x000D_
.column1 {_x000D_
  display: table-column;_x000D_
  background-color: green;_x000D_
}_x000D_
.column2 {_x000D_
  display: table-column;_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 1</div>_x000D_
    <div class="mycell">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 2</div>_x000D_
    <div class="mycell">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

OPTIONAL: both "rows" and "columns" can be styled by assigning multiple classes to each row and cell as follows. This approach gives maximum flexibility in specifying various sets of cells, or individual cells, to be styled:

//Useful css declarations, depending on what you want to affect, include:_x000D_
_x000D_
/* all cells (that have "class=mycell") */_x000D_
.mycell {_x000D_
}_x000D_
_x000D_
/* class row1, wherever it is used */_x000D_
.row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 (if you've put "class=mycell" on each cell) */_x000D_
.row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 */_x000D_
.row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows */_x000D_
.cell1 {_x000D_
}_x000D_
_x000D_
/* row1 inside class mytable (so can have different tables with different styles) */_x000D_
.mytable .row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 of a mytable */_x000D_
.mytable .row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 of a mytable */_x000D_
.mytable .row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows of a mytable */_x000D_
.mytable .cell1 {_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow row1">_x000D_
    <div class="mycell cell1">contents of first cell in row 1</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow row2">_x000D_
    <div class="mycell cell1">contents of first cell in row 2</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

In today's flexible designs, which use <div> for multiple purposes, it is wise to put some class on each div, to help refer to it. Here, what used to be <tr> in HTML became class myrow, and <td> became class mycell. This convention is what makes the above CSS selectors useful.

PERFORMANCE NOTE: putting class names on each cell, and using the above multi-class selectors, is better performance than using selectors ending with *, such as .row1 * or even .row1 > *. The reason is that selectors are matched last first, so when matching elements are being sought, .row1 * first does *, which matches all elements, and then checks all the ancestors of each element, to find if any ancestor has class row1. This might be slow in a complex document on a slow device. .row1 > * is better, because only the immediate parent is examined. But it is much better still to immediately eliminate most elements, via .row1 .cell1. (.row1 > .cell1 is an even tighter spec, but it is the first step of the search that makes the biggest difference, so it usually isn't worth the clutter, and the extra thought process as to whether it will always be a direct child, of adding the child selector >.)

The key point to take away re performance is that the last item in a selector should be as specific as possible, and should never be *.

If the number of fields in the CSV is constant then you could do something like this:

select a[1], a[2], a[3], a[4]
from (
    select regexp_split_to_array('a,b,c,d', ',')
) as dt(a)

For example:

=> select a[1], a[2], a[3], a[4] from (select regexp_split_to_array('a,b,c,d', ',')) as dt(a);
 a | a | a | a 
---+---+---+---
 a | b | c | d
(1 row)

If the number of fields in the CSV is not constant then you could get the maximum number of fields with something like this:

select max(array_length(regexp_split_to_array(csv, ','), 1))
from your_table

and then build the appropriate a[1], a[2], ..., a[M] column list for your query. So if the above gave you a max of 6, you'd use this:

select a[1], a[2], a[3], a[4], a[5], a[6]
from (
    select regexp_split_to_array(csv, ',')
    from your_table
) as dt(a)

You could combine those two queries into a function if you wanted.

For example, give this data (that's a NULL in the last row):

=> select * from csvs;
     csv     
-------------
 1,2,3
 1,2,3,4
 1,2,3,4,5,6

(4 rows)

=> select max(array_length(regexp_split_to_array(csv, ','), 1)) from csvs;
 max 
-----
   6
(1 row)

=> select a[1], a[2], a[3], a[4], a[5], a[6] from (select regexp_split_to_array(csv, ',') from csvs) as dt(a);
 a | a | a | a | a | a 
---+---+---+---+---+---
 1 | 2 | 3 |   |   | 
 1 | 2 | 3 | 4 |   | 
 1 | 2 | 3 | 4 | 5 | 6
   |   |   |   |   | 
(4 rows)

Since your delimiter is a simple fixed string, you could also use string_to_array instead of regexp_split_to_array:

select ...
from (
    select string_to_array(csv, ',')
    from csvs
) as dt(a);

Thanks to Michael for the reminder about this function.

You really should redesign your database schema to avoid the CSV column if at all possible. You should be using an array column or a separate table instead.

In my case I was sending in correct object in ResponseEntity<>().

Correct :

@PostMapping(value = "/get-customer-details", produces = { MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<?> getCustomerDetails(@RequestBody String requestMessage) throws JSONException {
    JSONObject jsonObject = new JSONObject();
    jsonObject.put("customerId", "123");
    jsonObject.put("mobileNumber", "XXX-XXX-XXXX");
    return new ResponseEntity<>(jsonObject.toString(), HttpStatus.OK);
}

Incorrect :

return new ResponseEntity<>(jsonObject, HttpStatus.OK);

Because, jsonObject's toString() method "Encodes the jsonObject as a compact JSON string". Therefore, Spring returns json string directly without any further serialization.

When we send jsonObject instead, Spring tries to serialize it based on produces method used in RequestMapping and fails due to it "Could not find acceptable representation".

With the release of the latest Android Support Library (rev 22.2.0) we've got a Design Support Library and as part of this a new view called NavigationView. So instead of doing everything on our own with the ScrimInsetsFrameLayout and all the other stuff we simply use this view and everything is done for us.

Example

Step 1

Add the Design Support Library to your build.gradle file

dependencies {
    // Other dependencies like appcompat
    compile 'com.android.support:design:22.2.0'
}

Step 2

Add the NavigationView to your DrawerLayout:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:app="http://schemas.android.com/apk/res-auto"
     android:id="@+id/drawer_layout"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:fitsSystemWindows="true"> <!-- this is important -->

     <!-- Your contents -->

     <android.support.design.widget.NavigationView
         android:id="@+id/navigation"
         android:layout_width="wrap_content"
         android:layout_height="match_parent"
         android:layout_gravity="start"
         app:menu="@menu/navigation_items" /> <!-- The items to display -->
 </android.support.v4.widget.DrawerLayout>

Step 3

Create a new menu-resource in /res/menu and add the items and icons you wanna display:

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_home"
            android:icon="@drawable/ic_action_home"
            android:title="Home" />
        <item
            android:id="@+id/nav_example_item_1"
            android:icon="@drawable/ic_action_dashboard"
            android:title="Example Item #1" />
    </group>

    <item android:title="Sub items">
        <menu>
            <item
                android:id="@+id/nav_example_sub_item_1"
                android:title="Example Sub Item #1" />
        </menu>
    </item>

</menu>

Step 4

Init the NavigationView and handle click events:

public class MainActivity extends AppCompatActivity {

    NavigationView mNavigationView;
    DrawerLayout mDrawerLayout;

    // Other stuff

    private void init() {
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mNavigationView = (NavigationView) findViewById(R.id.navigation_view);
        mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(MenuItem menuItem) {
                mDrawerLayout.closeDrawers();
                menuItem.setChecked(true);
                switch (menuItem.getItemId()) {
                    case R.id.nav_home:
                        // TODO - Do something
                        break;
                    // TODO - Handle other items
                }
                return true;
            }
        });
    }
}

Step 5

Be sure to set android:windowDrawsSystemBarBackgrounds and android:statusBarColor in values-v21 otherwise your Drawer won`t be displayed "under" the StatusBar

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Other attributes like colorPrimary, colorAccent etc. -->
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

Optional Step

Add a Header to the NavigationView. For this simply create a new layout and add app:headerLayout="@layout/my_header_layout" to the NavigationView.

Result

Notes

• The highlighted color uses the color defined via the colorPrimary attribute
• The List Items use the color defined via the textColorPrimary attribute
• The Icons use the color defined via the textColorSecondary attribute

You can also check the example app by Chris Banes which highlights the NavigationView along with the other new views that are part of the Design Support Library (like the FloatingActionButton, TextInputLayout, Snackbar, TabLayout etc.)

When you use string literals, such as "this is a string" and in your case "sssss" and "kkkk", the compiler puts them in read-only memory. However, strcat attempts to write the second argument after the first. You can solve this problem by making a sufficiently sized destination buffer and write to that.

char destination[10]; // 5 times s, 4 times k, one zero-terminator
char* str1;
char* str2;
str1 = "sssss";
str2 = "kkkk";
strcpy(destination, str1);
printf("%s",strcat(destination,str2));

Note that in recent compilers, you usually get a warning for casting string literals to non-const character pointers.

Do you need to look up objects by the key? If not, consider using List<Tuple<string, string>> or List<KeyValuePair<string, string>> if you're not using .NET 4.

If you are using .NET 3.5+ you could use LINQ (Language INtegrated Query).

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

I failed even if I tried to update the SDK tools as mentioned here.

Here is how I solved the problem (for the library projects imported).

In File -> Project Structure -> Modules, I removed the problematic projects, and added them again by selecting New Module -> Android Library Module.

After rebuilding the project, I got all the R.java files back.

I change my monitor DPI settings from the launch options of AVD and synchronized it with the original and current setting of my monitor, and it worked.

select * from tbl where (endDate>=@starDate and startDate<=@endDate)

attached the diagram for explanation

storing simple data in DB StartDate =10/01/2020 and endDate=20/01/2020. user can provide @startDate(d1) and @endDate(d2) to search.

here 6 scenarios can happen depicted by the 4 red lines (match data) 2 green lines (no match data).

so by conclusion from the image, to get data from DB by providing d1,d2. ED must be greater than d1(@startDate) and SD must be less than d2(@endDate).

An approximation of what I was doing:

import module.submodule

class MyClass:
    constant = submodule.constant

To which pylint said: E: 4,15: Undefined variable 'submodule' (undefined-variable)

I resolved this by changing my import like:

from module.submodule import CONSTANT

class MyClass:
    constant = CONSTANT

Note: I also renamed by imported variable to have an uppercase name to reflect its constant nature.

Solution with TC - O(n) and SC - O(1)

public String reverseString(String str){
    String str = "Hello Wrold";
    int start = 0;

    for (int i = 0; i < str.length(); i++) {

        if (str.charAt(i) == ' ' || i == str.length() - 1) {

            int end = 0;

            if (i == str.length() - 1) {
                end = i;
            } else {
                end = i - 1;
            }

            str = swap(str, start, end);
            start = i + 1;
        }
    }
    System.out.println(str);
   }

 private static String swap(String str, int start, int end) {

    StringBuilder sb = new StringBuilder(str);

    while (start < end) {
        sb.setCharAt(start, str.charAt(end));
        sb.setCharAt(end, str.charAt(start));
        start++;
        end--;
    }
    return sb.toString();
}

Try this:

reverse = 0;
    remainder = 0;
    count = 0;
    while (number > reverse)
    {
        remainder = number % 10;
        reverse = reverse * 10 + remainder;
        number = number / 10;
        count++;
    }
    Console.WriteLine(count);
    if (reverse == number)
    {
        Console.WriteLine("Your number is a palindrome");
    }
    else
    {
        number = number * 10 + remainder;
        if (reverse == number)
            Console.WriteLine("your number is a palindrome");
        else
            Console.WriteLine("your number is not a palindrome");
    }
    Console.ReadLine();
}
}

When I faced this issue, I discovered that my problem was that the files in the 'Source Account' were copied there by a 'third party' and the Owner was not the Source Account.

I had to recopy the objects to themselves in the same bucket with the --metadata-directive REPLACE

An easy way to achieve this is to just use aliases on the columns in your query.

If your database column is PERSON_ID and your object's property is ID, you can just do

select PERSON_ID as Id ...

in your query and Dapper will pick it up as expected.

If you want to do manually then You also can clear your user data by clicking “Clear Data” button in Settings–>Applications–>Manage Aplications–> YOUR APPLICATION

or Is there any other way to do that?

Ideally, a compiler would optimize the second, but it's not required. The first is the best way. However, it's pretty critical to understand the distinction between stack and heap in C++, sine you must manage your own heap memory.

Try:

select
     id,
     StartDate,
CASE WHEN StartDate IS NULL
    THEN 'Awaiting'
    ELSE 'Approved' END AS StartDateStatus
FROM myTable

You code would have been doing a When StartDate = NULL, I think.

NULL is never equal to NULL (as NULL is the absence of a value). NULL is also never not equal to NULL. The syntax noted above is ANSI SQL standard and the converse would be StartDate IS NOT NULL.

You can run the following:

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

And this returns:

EqualityCheck = 0
InEqualityCheck = 0
NullComparison = 1

For completeness, in SQL Server you can:

SET ANSI_NULLS OFF;

Which would result in your equals comparisons working differently:

SET ANSI_NULLS OFF

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

Which returns:

EqualityCheck = 1
InEqualityCheck = 0
NullComparison = 1

But I would highly recommend against doing this. People subsequently maintaining your code might be compelled to hunt you down and hurt you...

Also, it will no longer work in upcoming versions of SQL server:

https://msdn.microsoft.com/en-GB/library/ms188048.aspx

If you are using the Spring Framework then you have the StringUtils class:

import static org.springframework.util.StringUtils.arrayToDelimitedString;

arrayToDelimitedString(new String[] {"A", "B", "C"}, "\n");

Like bruno said, you're better configuring it yourself. Here's how I do it. Start by creating a properties file (/etc/myapp/config.properties).

javax.net.ssl.keyStore = /etc/myapp/keyStore
javax.net.ssl.keyStorePassword = 123456

Then load the properties to your environment from your code. This makes your application configurable.

FileInputStream propFile = new FileInputStream("/etc/myapp/config.properties");
Properties p = new Properties(System.getProperties());
p.load(propFile);
System.setProperties(p);

i know what went wrong you see you used "" instead of '' in this

$target_Path = $target_Path.basename( 

   "myFile.png"

);

Here is another way:

df['rnd'] = np.random.rand(len(df)) df = df.sort_values(by='rnd', inplace=True).drop('rnd', axis=1)

function include(file){
return new Promise(function(resolve, reject){
        var script = document.createElement('script');
        script.src = file;
        script.type ='text/javascript';
        script.defer = true;
        document.getElementsByTagName('head').item(0).appendChild(script);

        script.onload = function(){
        resolve()
        }
        script.onerror = function(){
          reject()
        }
      })

 /*I HAVE MODIFIED THIS TO  BE PROMISE-BASED 
   HOW TO USE THIS FUNCTION 

  include('js/somefile.js').then(function(){
  console.log('loaded');
  },function(){
  console.log('not loaded');
  })
  */
}

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

Stack frame is the packed information related to a function call. This information generally includes arguments passed to th function, local variables and where to return upon terminating. Activation record is another name for a stack frame. The layout of the stack frame is determined in the ABI by the manufacturer and every compiler supporting the ISA must conform to this standard, however layout scheme can be compiler dependent. Generally stack frame size is not limited but there is a concept called "red/protected zone" to allow system calls...etc to execute without interfering with a stack frame.

There is always a SP but on some ABIs (ARM's and PowerPC's for example) FP is optional. Arguments that needed to be placed onto the stack can be offsetted using the SP only. Whether a stack frame is generated for a function call or not depends on the type and number of arguments, local variables and how local variables are accessed generally. On most ISAs, first, registers are used and if there are more arguments than registers dedicated to pass arguments these are placed onto the stack (For example x86 ABI has 6 registers to pass integer arguments). Hence, sometimes, some functions do not need a stack frame to be placed on the stack, just the return address is pushed onto the stack.

You could just use list comprehension:

property_asel = [val for is_good, val in zip(good_objects, property_a) if is_good]

or

property_asel = [property_a[i] for i in good_indices]

The latter one is faster because there are fewer good_indices than the length of property_a, assuming good_indices are precomputed instead of generated on-the-fly.

Edit: The first option is equivalent to itertools.compress available since Python 2.7/3.1. See @Gary Kerr's answer.

property_asel = list(itertools.compress(property_a, good_objects))

If you're using jackson, better to convert directly to ObjectNode.

//not including SerializationFeatures for brevity
static final ObjectMapper mapper = new ObjectMapper();

//pass it your payload
public static ObjectNode convObjToONode(Object o) {
    StringWriter stringify = new StringWriter();
    ObjectNode objToONode = null;

    try {
        mapper.writeValue(stringify, o);
        objToONode = (ObjectNode) mapper.readTree(stringify.toString());
    } catch (IOException e) {
        e.printStackTrace();
    }

    System.out.println(objToONode);
    return objToONode;
}

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

PHP extensions for Ubuntu 20.04 LTS (Focal Fossa)

PHP extensions for Ubuntu 18.04 LTS (Bionic)

PHP extensions for Ubuntu 16.04 LTS (Xenial)

Try

sudo systemctl start postgresql@12-main

Here my postgresql version is 12.

With the release of Android Oreo you can use the support library to reach this goal.

1. Check in your app build.gradle if you have the support library >= 26.0.0
2. Add "font" folder to your resources folder and add your fonts there

3. Reference your default font family in your app main style:

   <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
      <item name="android:fontFamily">@font/your_font</item>
      <item name="fontFamily">@font/your_font</item> <!-- target android sdk versions < 26 and > 14 if theme other than AppCompat -->
   </style>
   

Check https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml.html for more detailed information.

If you're dealing with fixed number of keys that you know in advance, use Python's inbuilt namedtuples instead. A possible use-case is when you want to store some constant data and access it throughout the program by both indexing and specifying keys.

import collections
ordered_keys = ['foo', 'bar']
D = collections.namedtuple('D', ordered_keys)
d = D(foo='python', bar='spam')

Access by indexing:

d[0] # result: python
d[1] # result: spam

Access by specifying keys:

d.foo # result: python
d.bar # result: spam

Or better:

getattr(d, 'foo') # result: python
getattr(d, 'bar') # result: spam

import string
import random
n = 10

p = ''

while (string.ascii_uppercase not in p) and (string.ascii_lowercase not in p) and (string.digits not in p):
    for _ in range(n):
        state = random.randint(0, 2)
        if state == 0:
            p = p + chr(random.randint(97, 122))
        elif state == 1:
            p = p + chr(random.randint(65, 90))
        else:
            p = p + str(random.randint(0, 9))
    break
print(p)

This code generates a sequence with size n which at least contain an uppercase, lowercase, and a digit. By using the while loop, we have guaranteed this event.

Try this:

"

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

you have to use this code:

with <%@ taglib prefix="c" uri="http://www.springframework.org/tags/form"%>

and

<c:select>
            <option value="RCV"
                ${records[0].getDirection() == 'RCV' ? 'selected="true"' : ''}>
                <spring:message code="dropdown.Incoming" text="dropdown.Incoming" />
            </option>
            <option value="SND"
                ${records[0].getDirection() == 'SND'? 'selected="true"' : ''}>
                <spring:message code="dropdown.Outgoing" text="dropdown.Outgoing" />
            </option>
        </c:select>

One solution is doing the sum:

=SUM(COUNTIFS(A1:A196,{"yes","no"},B1:B196,"agree"))

or know its not the countifs but the sumproduct will do it in one line:

=SUMPRODUCT(((A1:A196={"yes","no"})*(j1:j196="agree")))

if I have understood correct the question :

Use np.delete ! It does not actually delete anything inplace

Example:

import numpy as np
a = np.array([[1,4],[5,7],[3,1]])                                       

# a: array([[1, 4],
#           [5, 7],
#           [3, 1]])

ind = np.array([0,1])                                                   

# ind: array([0, 1])

# a[ind]: array([[1, 4],
#                [5, 7]])

all_except_index = np.delete(a, ind, axis=0)                                              
# all_except_index: array([[3, 1]])

# a: (still the same): array([[1, 4],
#                             [5, 7],
#                             [3, 1]])

You can use a web-service from http://ip-api.com
in your php code, do as follow :

<?php
$ip = $_REQUEST['REMOTE_ADDR']; // the IP address to query
$query = @unserialize(file_get_contents('http://ip-api.com/php/'.$ip));
if($query && $query['status'] == 'success') {
  echo 'Hello visitor from '.$query['country'].', '.$query['city'].'!';
} else {
  echo 'Unable to get location';
}
?>

the query have many other informations:

array (
  'status'      => 'success',
  'country'     => 'COUNTRY',
  'countryCode' => 'COUNTRY CODE',
  'region'      => 'REGION CODE',
  'regionName'  => 'REGION NAME',
  'city'        => 'CITY',
  'zip'         => ZIP CODE,
  'lat'         => LATITUDE,
  'lon'         => LONGITUDE,
  'timezone'    => 'TIME ZONE',
  'isp'         => 'ISP NAME',
  'org'         => 'ORGANIZATION NAME',
  'as'          => 'AS NUMBER / NAME',
  'query'       => 'IP ADDRESS USED FOR QUERY',
)

The error message seems self-explanatory. You can't instantiate an instance of an interface, and you've declared IUser as an interface. (The same rule applies to abstract classes.) The whole point of an interface is that it doesn't do anything—there is no implementation provided for its methods.

However, you can instantiate an instance of a class that implements that interface (provides an implementation for its methods), which in your case is the User class.

Thus, your code needs to look like this:

IUser user = new User();

This instantiates an instance of the User class (which provides the implementation), and assigns it to an object variable for the interface type (IUser, which provides the interface, the way in which you as the programmer can interact with the object).

Of course, you could also write:

User user = new User();

which creates an instance of the User class and assigns it to an object variable of the same type, but that sort of defeats the purpose of a defining a separate interface in the first place.

The var_dump equivalent in JavaScript? Simply, there isn't one.

But, that doesn't mean you're left helpless. Like some have suggested, use Firebug (or equivalent in other browsers), but unlike what others suggested, don't use console.log when you have a (slightly) better tool console.dir:

console.dir(object)

Prints an interactive listing of all properties of the object. This looks identical to the view that you would see in the DOM tab.

Use document.title.

See this page for a rudimentary tutorial as well.

If you want it in pure CSS:

pointer-events:none;

AFAICU, your distribution is discrete (and nothing but discrete). Therefore just counting the frequencies of different values and normalizing them should be enough for your purposes. So, an example to demonstrate this:

In []: values= [0, 0, 0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 3, 3, 4]
In []: counts= asarray(bincount(values), dtype= float)
In []: cdf= counts.cumsum()/ counts.sum()

Thus, probability of seeing values higher than 1 is simply (according to the complementary cumulative distribution function (ccdf):

In []: 1- cdf[1]
Out[]: 0.40000000000000002

Please note that ccdf is closely related to survival function (sf), but it's also defined with discrete distributions, whereas sf is defined only for contiguous distributions.

This is really annoying problem to fix but you can try these.

First of all, make sure the file is actually saved in UTF-8 format.

Then check that you have <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"> in your HTML header.

You can also try calling header('Content-Type: text/html; charset=utf-8'); at the beginning of your PHP script or adding AddDefaultCharset UTF-8 to your .htaccess file.

Just clean the project

If this does not work try the other solutions

I saw Veer's answer. I think it's right, but it did not I work for me. Maybe I am using .NET 4 and am using 64x OS so kindly check this.

You may put in setup or check it in start-up of your application:

private void Form1_Load(object sender, EventArgs e)
{
    var appName = Process.GetCurrentProcess().ProcessName + ".exe";
    SetIE8KeyforWebBrowserControl(appName);
}

private void SetIE8KeyforWebBrowserControl(string appName)
{
    RegistryKey Regkey = null;
    try
    {
        // For 64 bit machine
        if (Environment.Is64BitOperatingSystem)
            Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Wow6432Node\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
        else  //For 32 bit machine
            Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);

        // If the path is not correct or
        // if the user haven't priviledges to access the registry
        if (Regkey == null)
        {
            MessageBox.Show("Application Settings Failed - Address Not found");
            return;
        }

        string FindAppkey = Convert.ToString(Regkey.GetValue(appName));

        // Check if key is already present
        if (FindAppkey == "8000")
        {
            MessageBox.Show("Required Application Settings Present");
            Regkey.Close();
            return;
        }

        // If a key is not present add the key, Key value 8000 (decimal)
        if (string.IsNullOrEmpty(FindAppkey))
            Regkey.SetValue(appName, unchecked((int)0x1F40), RegistryValueKind.DWord);

        // Check for the key after adding
        FindAppkey = Convert.ToString(Regkey.GetValue(appName));

        if (FindAppkey == "8000")
            MessageBox.Show("Application Settings Applied Successfully");
        else
            MessageBox.Show("Application Settings Failed, Ref: " + FindAppkey);
    }
    catch (Exception ex)
    {
        MessageBox.Show("Application Settings Failed");
        MessageBox.Show(ex.Message);
    }
    finally
    {
        // Close the Registry
        if (Regkey != null)
            Regkey.Close();
    }
}

You may find messagebox.show, just for testing.

Keys are as the following:

• 11001 (0x2AF9) - Internet Explorer 11. Webpages are displayed in IE11 edge mode, regardless of the !DOCTYPE directive.

• 11000 (0x2AF8) - Internet Explorer 11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 edge mode. Default value for IE11.

• 10001 (0x2711)- Internet Explorer 10. Webpages are displayed in IE10 Standards mode, regardless of the !DOCTYPE directive.

• 10000 (0x2710)- Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. Default value for Internet Explorer 10.

• 9999 (0x270F) - Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive.

• 9000 (0x2328) - Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode.

Here is the right way to do imports in Java.

import Dan.Vik;
class Kab
{
public static void main(String args[])
{
    Vik Sam = new Vik();
    Sam.disp();
}
}

You don't import methods in java. There is an advanced usage of static imports but basically you just import packages and classes. If the function you are importing is a static function you can do a static import, but I don't think you are looking for static imports here.

Asynchronous way to achieve it.

void inputStreamToOutputStream(final InputStream inputStream, final OutputStream out) {
    Thread t = new Thread(new Runnable() {

        public void run() {
            try {
                int d;
                while ((d = inputStream.read()) != -1) {
                    out.write(d);
                }
            } catch (IOException ex) {
                //TODO make a callback on exception.
            }
        }
    });
    t.setDaemon(true);
    t.start();
}

You can try a box-shadow inset

something like this: box-shadow:inset 0px -5px 0px 0px #fff

adds a white 5px border to the bottom of the element without increasing the size

You can do what you want if you use an iterator object to go over the elements in your set. You can remove them on the go an it's ok. However removing them while in a for loop (either "standard", of the for each kind) will get you in trouble:

Set<Integer> set = new TreeSet<Integer>();
    set.add(1);
    set.add(2);
    set.add(3);

    //good way:
    Iterator<Integer> iterator = set.iterator();
    while(iterator.hasNext()) {
        Integer setElement = iterator.next();
        if(setElement==2) {
            iterator.remove();
        }
    }

    //bad way:
    for(Integer setElement:set) {
        if(setElement==2) {
            //might work or might throw exception, Java calls it indefined behaviour:
            set.remove(setElement);
        } 
    }

As per @mrgloom's comment, here are more details as to why the "bad" way described above is, well... bad :

Without getting into too much details about how Java implements this, at a high level, we can say that the "bad" way is bad because it is clearly stipulated as such in the Java docs:

https://docs.oracle.com/javase/8/docs/api/java/util/ConcurrentModificationException.html

stipulate, amongst others, that (emphasis mine):

"For example, it is not generally permissible for one thread to modify a Collection while another thread is iterating over it. In general, the results of the iteration are undefined under these circumstances. Some Iterator implementations (including those of all the general purpose collection implementations provided by the JRE) may choose to throw this exception if this behavior is detected" (...)

"Note that this exception does not always indicate that an object has been concurrently modified by a different thread. If a single thread issues a sequence of method invocations that violates the contract of an object, the object may throw this exception. For example, if a thread modifies a collection directly while it is iterating over the collection with a fail-fast iterator, the iterator will throw this exception."

To go more into details: an object that can be used in a forEach loop needs to implement the "java.lang.Iterable" interface (javadoc here). This produces an Iterator (via the "Iterator" method found in this interface), which is instantiated on demand, and will contain internally a reference to the Iterable object from which it was created. However, when an Iterable object is used in a forEach loop, the instance of this iterator is hidden to the user (you cannot access it yourself in any way).

This, coupled with the fact that an Iterator is pretty stateful, i.e. in order to do its magic and have coherent responses for its "next" and "hasNext" methods it needs that the backing object is not changed by something else than the iterator itself while it's iterating, makes it so that it will throw an exception as soon as it detects that something changed in the backing object while it is iterating over it.

Java calls this "fail-fast" iteration: i.e. there are some actions, usually those that modify an Iterable instance (while an Iterator is iterating over it). The "fail" part of the "fail-fast" notion refers to the ability of an Iterator to detect when such "fail" actions happen. The "fast" part of the "fail-fast" (and, which in my opinion should be called "best-effort-fast"), will terminate the iteration via ConcurrentModificationException as soon as it can detect that a "fail" action has happen.

You can use the get_group method:

In [21]: gb.get_group('foo')
Out[21]: 
     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

Note: This doesn't require creating an intermediary dictionary / copy of every subdataframe for every group, so will be much more memory-efficient than creating the naive dictionary with dict(iter(gb)). This is because it uses data-structures already available in the groupby object.

You can select different columns using the groupby slicing:

In [22]: gb[["A", "B"]].get_group("foo")
Out[22]:
     A         B
0  foo  1.624345
2  foo -0.528172
4  foo  0.865408

In [23]: gb["C"].get_group("foo")
Out[23]:
0     5
2    11
4    14
Name: C, dtype: int64

The best way to implement this is as follows:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

rootView = inflater.inflate(R.layout.testclassfragment, container, false);
        ImageView imageView = (ImageView) rootView.findViewById(R.id.my_image);
        return rootView
}

In this way, the rootView can be used for each control defined in the xml layout and the code is much cleaner in this way.

Hope this helps :)

Modified shA.t's query for more clarity:

-- t1 left join t2
SELECT t1.value, t2.value
FROM t1 LEFT JOIN t2 ON t1.value = t2.value   

    UNION ALL -- include duplicates

-- t1 right exclude join t2 (records found only in t2)
SELECT t1.value, t2.value
FROM t1 RIGHT JOIN t2 ON t1.value = t2.value
WHERE t1.value IS NULL 

If all you want is calling ravel on your (nested, I s'pose?) list, you can do that directly, numpy will do the casting for you:

L = [[1,None,3],["The", "quick", object]]
np.ravel(L)
# array([1, None, 3, 'The', 'quick', <class 'object'>], dtype=object)

Also worth mentioning that you needn't go through numpy at all.

Slightly more "Angular way" would be to use the straightforward limitTo filter, as natively provided by Angular:

<ul class="phones">
  <li ng-repeat="phone in phones | filter:query | orderBy:orderProp | limitTo:quantity">
    {{phone.name}}
    <p>{{phone.snippet}}</p>
  </li>
</ul>

app.controller('PhoneListCtrl', function($scope, $http) {
    $http.get('phones.json').then(
      function(phones){
        $scope.phones = phones.data;
      }
    );
    $scope.orderProp = 'age';
    $scope.quantity = 5;
  }
);

I would recommend the read_csv function from the pandas library:

import pandas as pd
df=pd.read_csv('myfile.csv', sep=',',header=None)
df.values
array([[ 1. ,  2. ,  3. ],
       [ 4. ,  5.5,  6. ]])

This gives a pandas DataFrame - allowing many useful data manipulation functions which are not directly available with numpy record arrays.

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table...

I would also recommend genfromtxt. However, since the question asks for a record array, as opposed to a normal array, the dtype=None parameter needs to be added to the genfromtxt call:

Given an input file, myfile.csv:

1.0, 2, 3
4, 5.5, 6

import numpy as np
np.genfromtxt('myfile.csv',delimiter=',')

gives an array:

array([[ 1. ,  2. ,  3. ],
       [ 4. ,  5.5,  6. ]])

and

np.genfromtxt('myfile.csv',delimiter=',',dtype=None)

gives a record array:

array([(1.0, 2.0, 3), (4.0, 5.5, 6)], 
      dtype=[('f0', '<f8'), ('f1', '<f8'), ('f2', '<i4')])

This has the advantage that file with multiple data types (including strings) can be easily imported.

See the exec maven plugin. You can run Java classes using:

mvn exec:java -Dexec.mainClass="com.example.Main" [-Dexec.args="argument1"] ...

The invocation can be as simple as mvn exec:java if the plugin configuration is in your pom.xml. The plugin site on Mojohaus has a more detailed example.

After trying everything here twice in different order, I reinstalled everything and before doing cordova platform add android I went to templates/gradle and ran gradlew.bat. After this completed, I was able to add the android platform without any problem.

@files is an existing array

my @new_values =  grep(/^2[\d].[\d][A-za-z]?/,@files);

print join("\n", @new_values);

print "\n";

/^2[\d].[\d][A-za-z]?/ = vaues starting from 2 here you can put any regular expression

You can start by installing the below given command in the conda environment:

conda install pip

Followed by installing all pip packages you need in the environment.

After installing all the conda and pip packages to export the environment use:

conda env export -n <env-name> > environment.yml

This will create the required file in the folder

I'm not sure why previous answers haven't suggested that the original poster set up a shell profile (bashrc, .tcshrc, etc.) that executed their commands automatically every time they log in on the server side.

The quest that brought me to this page for help was a bit different -- I wanted multiple PuTTY shortcuts for the same host that would execute different startup commands.

I came up with two solutions, both of which worked:

(background) I have a folder with a variety of PuTTY shortcuts, each with the "target" property in the shortcut tab looking something like:

"C:\Program Files (x86)\PuTTY\putty.exe" -load host01

with each load corresponding to a PuTTY profile I'd saved (with different hosts in the "Session" tab). (Mostly they only differ in color schemes -- I like to have each group of related tasks share a color scheme in the terminal window, with critical tasks, like logging in as root on a production system, performed only in distinctly colored windows.)

The folder's Windows properties are set to very clean and stripped down -- it functions as a small console with shortcut icons for each of my frequent remote PuTTY and RDP connections.

(solution 1) As mentioned in other answers the -m switch is used to configure a script on the Windows side to run, the -t switch is used to stay connected, but I found that it was order-sensitive if I wanted to get it to run without exiting

What I finally got to work after a lot of trial and error was:

(shortcut target field):

"C:\Program Files (x86)\PuTTY\putty.exe" -t -load "SSH Proxy" -m "C:\Users\[me]\Documents\hello-world-bash.txt"

where the file being executed looked like

echo "Hello, World!"
echo ""
export PUTTYVAR=PROXY
/usr/local/bin/bash

(no semicolons needed)

This runs the scripted command (in my case just printing "Hello, world" on the terminal) and sets a variable that my remote session can interact with.

Note for debugging: when you run PuTTY it loads the -m script, if you edit the script you need to re-launch PuTTY instead of just restarting the session.

(solution 2) This method feels a lot cleaner, as the brains are on the remote Unix side instead of the local Windows side:

From Putty master session (not "edit settings" from existing session) load a saved config and in the SSH tab set remote command to:

export PUTTYVAR=GREEN; bash -l

Then, in my .bashrc, I have a section that performs different actions based on that variable:

case ${PUTTYVAR} in
  "")
    echo "" 
    ;;
  "PROXY")
    # this is the session config with all the SSH tunnels defined in it
    echo "";
    echo "Special window just for holding tunnels open." ;
    echo "";
    PROMPT_COMMAND='echo -ne "\033]0;Proxy Session @master01\$\007"'
    alias temppass="ssh keyholder.example.com makeonetimepassword"
    alias | grep temppass
    ;;
  "GREEN")
    echo "";
    echo "It's not easy being green"
    ;;
  "GRAY")
    echo ""
    echo "The gray ghost"
    ;;
  *)
    echo "";
    echo "Unknown PUTTYVAR setting ${PUTTYVAR}"
    ;;
esac

(solution 3, untried)

It should also be possible to have bash skip my .bashrc and execute a different startup script, by putting this in the PuTTY SSH command field:

bash --rcfile .bashrc_variant -l 

Adding to a_horse_with_no_name's answer you might find the following of interest...

it does not make any difference whether you declare a column as VARCHAR(100) or VACHAR(500).

-- try to create a table with max varchar length
drop table if exists foo;
create table foo(name varchar(65535) not null)engine=innodb;

MySQL Database Error: Row size too large.

-- try to create a table with max varchar length - 2 bytes for the length
drop table if exists foo;
create table foo(name varchar(65533) not null)engine=innodb;

Executed Successfully

-- try to create a table with max varchar length with nullable field
drop table if exists foo;
create table foo(name varchar(65533))engine=innodb;

MySQL Database Error: Row size too large.

-- try to create a table with max varchar length with nullable field
drop table if exists foo;
create table foo(name varchar(65532))engine=innodb;

Executed Successfully

Dont forget the length byte(s) and the nullable byte so:

name varchar(100) not null will be 1 byte (length) + up to 100 chars (latin1)

name varchar(500) not null will be 2 bytes (length) + up to 500 chars (latin1)

name varchar(65533) not null will be 2 bytes (length) + up to 65533 chars (latin1)

name varchar(65532) will be 2 bytes (length) + up to 65532 chars (latin1) + 1 null byte

Hope this helps :)

First of all install it

npm install jquery -S

After installing it, you can use it as below

import $ from 'jquery';
window.jQuery = window.$ = $;
$(selector).hide();

I faced to this problem a lot when developing my company's website using WordPress. Finally I found that it happened because me and my colleague update the website at the same time as well as we installed and activated many plugins that we did not use them. The solution for me was we update the website in different time and deactivated and uninstalled those plugins.

try this. works for me

$options = array(
    'cache_wsdl' => 0,
    'trace' => 1,
    'stream_context' => stream_context_create(array(
          'ssl' => array(
               'verify_peer' => false,
                'verify_peer_name' => false,
                'allow_self_signed' => true
          )
    ));

$client = new SoapClient(url, $options);

I ran into the same issue a while ago and did solve it by using reflection with some help from Jackson.

First populate a map with all the fields on an Object. Then add those map entries as parameters to the MockHttpServletRequestBuilder.

In this way you can use any Object and you are passing it as request parameters. I'm sure there are other solutions out there but this one worked for us:

    @Test
    public void testFormEdit() throws Exception {
        getMockMvc()
                .perform(
                        addFormParameters(post(servletPath + tableRootUrl + "/" + POST_FORM_EDIT_URL).servletPath(servletPath)
                                .param("entityID", entityId), validEntity)).andDo(print()).andExpect(status().isOk())
                .andExpect(content().contentType(MediaType.APPLICATION_JSON)).andExpect(content().string(equalTo(entityId)));
    }

    private MockHttpServletRequestBuilder addFormParameters(MockHttpServletRequestBuilder builder, Object object)
            throws IllegalAccessException, InvocationTargetException, NoSuchMethodException {

        SimpleDateFormat dateFormat = new SimpleDateFormat(applicationSettings.getApplicationDateFormat());

        Map<String, ?> propertyValues = getPropertyValues(object, dateFormat);

        for (Entry<String, ?> entry : propertyValues.entrySet()) {
            builder.param(entry.getKey(),
                    Util.prepareDisplayValue(entry.getValue(), applicationSettings.getApplicationDateFormat()));
        }

        return builder;
    }

    private Map<String, ?> getPropertyValues(Object object, DateFormat dateFormat) {
        ObjectMapper mapper = new ObjectMapper();
        mapper.setDateFormat(dateFormat);
        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        mapper.registerModule(new JodaModule());

        TypeReference<HashMap<String, ?>> typeRef = new TypeReference<HashMap<String, ?>>() {};

        Map<String, ?> returnValues = mapper.convertValue(object, typeRef);

        return returnValues;

    }

Here's a Python 3 solution using the built in wave module [1], that works for n channels, and 8,16,24... bits.

import sys
import wave

def read_wav(path):
    with wave.open(path, "rb") as wav:
        nchannels, sampwidth, framerate, nframes, _, _ = wav.getparams()
        print(wav.getparams(), "\nBits per sample =", sampwidth * 8)

        signed = sampwidth > 1  # 8 bit wavs are unsigned
        byteorder = sys.byteorder  # wave module uses sys.byteorder for bytes

        values = []  # e.g. for stereo, values[i] = [left_val, right_val]
        for _ in range(nframes):
            frame = wav.readframes(1)  # read next frame
            channel_vals = []  # mono has 1 channel, stereo 2, etc.
            for channel in range(nchannels):
                as_bytes = frame[channel * sampwidth: (channel + 1) * sampwidth]
                as_int = int.from_bytes(as_bytes, byteorder, signed=signed)
                channel_vals.append(as_int)
            values.append(channel_vals)

    return values, framerate

You can turn the result into a NumPy array.

import numpy as np

data, rate = read_wav(path)
data = np.array(data)

Note, I've tried to make it readable rather than fast. I found reading all the data at once was almost 2x faster. E.g.

with wave.open(path, "rb") as wav:
    nchannels, sampwidth, framerate, nframes, _, _ = wav.getparams()
    all_bytes = wav.readframes(-1)

framewidth = sampwidth * nchannels
frames = (all_bytes[i * framewidth: (i + 1) * framewidth]
            for i in range(nframes))

for frame in frames:
    ...

Although python-soundfile is roughly 2 orders of magnitude faster (hard to approach this speed with pure CPython).

Are you looking to play around with Reflection or are you looking to build a production piece of software? I would question why you're using reflection to set a property.

Double new_latitude;

Double.TryParse (value, out new_latitude);
ship.Latitude = new_latitude;

This should work

SELECT EXTRACTVALUE(column_name, '/DCResponse/ContextData/Decision') FROM traptabclob;

I have assumed the ** were just for highlighting?

For multiple files in ajax try this

        var url = "your_url";
        var data = $('#form').serialize();
        var form_data = new FormData(); 
        //get the length of file inputs   
        var length = $('input[type="file"]').length; 

        for(var i = 0;i<length;i++){
           file_data = $('input[type="file"]')[i].files;

            form_data.append("file_"+i, file_data[0]);
        }

            // for other data
            form_data.append("data",data);


        $.ajax({
                url: url,
                type: "POST",
                data: form_data,
                cache: false,
                contentType: false, //important
                processData: false, //important
                success: function (data) {
                  //do something
                }
        })

In php

        parse_str($_POST['data'], $_POST); 
        for($i=0;$i<count($_FILES);$i++){
              if(isset($_FILES['file_'.$i])){
                   $file = $_FILES['file_'.$i];
                   $file_name = $file['name'];
                   $file_type = $file ['type'];
                   $file_size = $file ['size'];
                   $file_path = $file ['tmp_name'];
              }
        }

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

R> de <- merge(d, e, by=0, all=TRUE)  # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0                 # replace NA values

eval is evil

eval("__import__('os').remove('important file')") # arbitrary commands
eval("9**9**9**9**9**9**9**9", {'__builtins__': None}) # CPU, memory

You can easily limit allowed range for each operation or any intermediate result, e.g., to limit input arguments for a**b:

def power(a, b):
    if any(abs(n) > 100 for n in [a, b]):
        raise ValueError((a,b))
    return op.pow(a, b)
operators[ast.Pow] = power

Or to limit magnitude of intermediate results:

                pass # not applicable

Greedy Approach

A greedy algorithm is an algorithm that follows the problem solving heuristic of making the locally optimal choice at each stage with the hope of finding a global optimum. In many problems, a greedy strategy does not in general produce an optimal solution, but nonetheless a greedy heuristic may yield locally optimal solutions that approximate a global optimal solution in a reasonable time.

We can make whatever choice seems best at the moment and then solve the subproblems that arise later. The choice made by a greedy algorithm may depend on choices made so far but not on future choices or all the solutions to the subproblem. It iteratively makes one greedy choice after another, reducing each given problem into a smaller one.

Dynamic programming

The idea behind dynamic programming is quite simple. In general, to solve a given problem, we need to solve different parts of the problem (subproblems), then combine the solutions of the subproblems to reach an overall solution. Often when using a more naive method, many of the subproblems are generated and solved many times. The dynamic programming approach seeks to solve each subproblem only once, thus reducing the number of computations: once the solution to a given subproblem has been computed, it is stored or "memo-ized": the next time the same solution is needed, it is simply looked up. This approach is especially useful when the number of repeating subproblems grows exponentially as a function of the size of the input.

Difference

Greedy choice property

We can make whatever choice seems best at the moment and then solve the subproblems that arise later. The choice made by a greedy algorithm may depend on choices made so far but not on future choices or all the solutions to the subproblem. It iteratively makes one greedy choice after another, reducing each given problem into a smaller one. In other words, a greedy algorithm never reconsiders its choices.

This is the main difference from dynamic programming, which is exhaustive and is guaranteed to find the solution. After every stage, dynamic programming makes decisions based on all the decisions made in the previous stage, and may reconsider the previous stage's algorithmic path to solution.

For example, let's say that you have to get from point A to point B as fast as possible, in a given city, during rush hour. A dynamic programming algorithm will look into the entire traffic report, looking into all possible combinations of roads you might take, and will only then tell you which way is the fastest. Of course, you might have to wait for a while until the algorithm finishes, and only then can you start driving. The path you will take will be the fastest one (assuming that nothing changed in the external environment).

On the other hand, a greedy algorithm will start you driving immediately and will pick the road that looks the fastest at every intersection. As you can imagine, this strategy might not lead to the fastest arrival time, since you might take some "easy" streets and then find yourself hopelessly stuck in a traffic jam.

Some other details...

In mathematical optimization, greedy algorithms solve combinatorial problems having the properties of matroids.

Dynamic programming is applicable to problems exhibiting the properties of overlapping subproblems and optimal substructure.

public static class Employee
{
    public static string SomeSetting
    {
        get 
        {
            return ConfigurationManager.AppSettings["SomeSetting"];    
        }
    }
}

Declare the property as static, as well. Also, Don't bother storing a private reference to ConfigurationManager.AppSettings. ConfigurationManager is already a static class.

If you feel that you must store a reference to appsettings, try

public static class Employee
{
    private static NameValueCollection _appSettings=ConfigurationManager.AppSettings;

    public static NameValueCollection AppSettings { get { return _appSettings; } }

}

It's good form to always give an explicit access specifier (private, public, etc) even though the default is private.

I hope i am understanding your question correctly, as the above comment says you need to provide more information.

In order to bind it to your view you would use property binding which is using [property]="value". Hope this helps.

<div *ngFor="let student of students">

I always use:

• NULL for pointers
• '\0' for chars
• 0.0 for floats and doubles

where 0 would do fine. It is a matter of signaling intent. That said, I am not anal about it.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import os
from flask import Flask, redirect, url_for

app = Flask(__name__)

@app.route('/')
def hello():
    return redirect(url_for('foo'))

@app.route('/foo')
def foo():
    return 'Hello Foo!'

if __name__ == '__main__':
    # Bind to PORT if defined, otherwise default to 5000.
    port = int(os.environ.get('PORT', 5000))
    app.run(host='0.0.0.0', port=port)

Take a look at the example in the documentation.

The JTextField offers a getText() and a setText() method - those are for getting and setting the content of the text field.

First you better set debug to TRUE:

$email->SMTPDebug = true;

Or temporary change value of public $SMTPDebug = false; in PHPMailer class.

And then you can see the full log in the browser. For me it was too many emails per second:

...
SMTP -> FROM SERVER:XXX.XX.XX.X Ok
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> get_lines(): $data is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> FROM SERVER:XXX.XX.XX.X Requested action not taken: too many emails per second
SMTP -> ERROR: DATA command not accepted from server: 550 5.7.0 Requested action not taken: too many emails per second
...

Thus I got to know what was the exact issue.

void main() {
  int decimals = 2;
  int fac = pow(10, decimals);
  double d = 1.234567889;
  d = (d * fac).round() / fac;
  print("d: $d");
}

Prints: 1.23

Here's one way:

import os
import shutil

def copy_over(path, from_name, to_name):
  for path, dirname, fnames in os.walk(path):
    for fname in fnames:
      if fname == from_name:
        shutil.copy(os.path.join(path, from_name), os.path.join(path, to_name))


copy_over('.', 'index.tpl', 'index.html')

You can use the collate clause in a query (I can't find my example right now, so my syntax is probably wrong - I hope it points you in the right direction)

select sone_field collate SQL_Latin1_General_CP850_CI_AI
  from table_1
    inner join table_2
      on (table_1.field collate SQL_Latin1_General_CP850_CI_AI = table_2.field)
  where whatever

With Eclipse Collections there are a few different ways to initialize a Set containing the characters 'a' and 'b' in one statement. Eclipse Collections has containers for both object and primitive types, so I illustrated how you could use a Set<String> or CharSet in addition to mutable, immutable, synchronized and unmodifiable versions of both.

Set<String> set =
    Sets.mutable.with("a", "b");
HashSet<String> hashSet =
    Sets.mutable.with("a", "b").asLazy().into(new HashSet<String>());
Set<String> synchronizedSet =
    Sets.mutable.with("a", "b").asSynchronized();
Set<String> unmodifiableSet =
    Sets.mutable.with("a", "b").asUnmodifiable();

MutableSet<String> mutableSet =
    Sets.mutable.with("a", "b");
MutableSet<String> synchronizedMutableSet =
    Sets.mutable.with("a", "b").asSynchronized();
MutableSet<String> unmodifiableMutableSet =
    Sets.mutable.with("a", "b").asUnmodifiable();

ImmutableSet<String> immutableSet =
    Sets.immutable.with("a", "b");
ImmutableSet<String> immutableSet2 =
    Sets.mutable.with("a", "b").toImmutable();

CharSet charSet =
    CharSets.mutable.with('a', 'b');
CharSet synchronizedCharSet =
    CharSets.mutable.with('a', 'b').asSynchronized();
CharSet unmodifiableCharSet =
    CharSets.mutable.with('a', 'b').asUnmodifiable();
MutableCharSet mutableCharSet =
    CharSets.mutable.with('a', 'b');
ImmutableCharSet immutableCharSet =
    CharSets.immutable.with('a', 'b');
ImmutableCharSet immutableCharSet2 =
    CharSets.mutable.with('a', 'b').toImmutable();

Use OpenFileDialog.SafeFileName

OpenFileDialog.SafeFileName Gets the file name and extension for the file selected in the dialog box. The file name does not include the path.

Just add these lines before headers.

Accurate format of .doc/docx files will be retrieved:

Have you added this gem to your gemfile?

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

move that gem out of assets group and then run bundle again, I hope that would help!

If you want to send additional parameters to the buttonClicked method, for example an indexPath or urlString, you can subclass the UIButton:

class SubclassedUIButton: UIButton {
    var indexPath: Int?
    var urlString: String?
}

Make sure to change the button's class in the identity inspector to subclassedUIButton. You can access the parameters inside the buttonClicked method using sender.indexPath or sender.urlString.

Note: If your button is inside a cell you can set the value of these additional parameters in the cellForRowAtIndexPath method (where the button is created).

Complementing @lasse-v-karlsen answer. To unblock all files recursively, run from powershell as administrator inside the folder you want:

gci -recurse | Unblock-File

source link: How to Unblock Files Downloaded from Internet? - Winhelponline
https://www.winhelponline.com/blog/bulk-unblock-files-downloaded-internet/

try

String[][] arrays = new String[5][];

I also had this problem. To sort out the problem of spaces in the middle of the string this line of code always works:

String field = field.replaceAll("\\s+", "");

You could also write your own Control for this, in case you want to use this more often. Assuming you have multiple TextBoxes in a Grid, it would look something like this:

public class AdvanceOnEnterTextBox : UserControl
{

    TextBox _TextBox;
    public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(String), typeof(AdvanceOnEnterTextBox), null);
    public static readonly DependencyProperty InputScopeProperty = DependencyProperty.Register("InputScope", typeof(InputScope), typeof(AdvanceOnEnterTextBox), null);


    public AdvanceOnEnterTextBox()
    {
        _TextBox = new TextBox();
        _TextBox.KeyDown += customKeyDown;
        Content = _TextBox;

    }


    /// <summary>
    /// Text for the TextBox
    /// </summary>
    public String Text
    {
        get { return _TextBox.Text; }
        set { _TextBox.Text = value; }
    }


    /// <summary>
    /// Inputscope for the Custom Textbox
    /// </summary>
    public InputScope InputScope
    {
        get { return _TextBox.InputScope; }
        set { _TextBox.InputScope = value; }
    }


    void customKeyDown(object sender, KeyEventArgs e)
    {
        if (!e.Key.Equals(Key.Enter)) return;

        var element = ((TextBox)sender).Parent as AdvanceOnEnterTextBox;
        if (element != null)
        {
            int currentElementPosition = ((Grid)element.Parent).Children.IndexOf(element);
            try
            {
                // Jump to the next AdvanceOnEnterTextBox (assuming, that Labels are inbetween).
                ((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition + 2)).Focus();
            }
            catch (Exception)
            {
                // Close Keypad if this was the last AdvanceOnEnterTextBox
                ((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition)).IsEnabled = false;
                ((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition)).IsEnabled = true;
            }
        }
    }
}

Here is the simple approach I used:

const element = event.currentTarget as HTMLInputElement
const value = element.value

The error shown by TypeScript compiler is gone and the code works.

Are you targeting the android.R or the one in your own project?

Are you sure your own R.java file is generated? Mistakes in your xml views could cause the R.java not to be generated. Go through your view files and make sure all the xml is right!

If your column with DATE datatype has value like below : -

value in column : 10-NOV-2005 06:31:00

Then, You can Use TRUNC function in select query to convert your date-time value to only date like - DD/MM/YYYY or DD-MON-YYYY

select TRUNC(column_1) from table1;

result : 10-NOV-2005

You will see above result - Provided that NLS_DATE_FORMAT is set as like below :-

Alter session NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';

If you want to assign a long str to variable, you can do it as below:

net_weights_pathname = (
    '/home/acgtyrant/BigDatas/'
    'model_configs/lenet_iter_10000.caffemodel')

Do not add any comma, or you will get a tuple which contains many strs!

Here is a query, you can run it in SQL Developer (or SQL*Plus):

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
  FROM DBA_SEGMENTS DS
  WHERE SEGMENT_NAME IN (SELECT TABLE_NAME FROM DBA_TABLES)
 GROUP BY DS.TABLESPACE_NAME,
       SEGMENT_NAME;

element.style comes from the markup.

<li style="display: none;">

Just remove the style attribute from the HTML.

Your software dependencies have an incompatible version conflict.

At the same time you want to install any Laravel 4.2.x version, and "zizaco/entrust" from its master branch. And that master branch requires at least Laravel 5.0 (roughly speaking).

The problem comes from the dependency on branches. It's likely that the package zizaco/entrust once was using Laravel 4.2 in its master branch, and that you were able to install your dependencies at that day. But the very moment this branch gets updated with an incompatible version requirement, you will never ever be able to run composer update and get updated dependencies.

Always use tagged versions! Ideally you use a relaxed version requirement that allows for compatible updates. This should be expressed as a tilde-two-number version requirement: ~1.2 would install a version 1.2.0 and up (like 1.2.99 or 1.2.100), and also 1.3 and up. If you need a certain patch release: Caret-three-number version ^1.2.10 will install 1.2.10 or up, also 1.3 and up.

Using this version requirement instead of dev-master will allow you to use released versions instead of the unstable state in the master branch, and allows you to address the most recent version that still works with Laravel 4.2. I guess that would be zizaco/entrust version 1.3.0, but version 1.2 would also qualify. Go with "zizaco/entrust": "~1.2".

To execute a file in the current directory, the syntax to use is: ./foo

As mentioned by allain, ./a.exe is the correct way to execute a.exe in the working directory using Cygwin.

Note: You may wish to use the -o parameter to cc to specify your own output filename. An example of this would be: cc helloworld.c -o helloworld.exe.

I wrote a simpler loop that works too (note that all my values are unique):

HashMap<Character, String> myHashMap = new HashMap<Character, String>();
HashMap<String, Character> reversedHashMap = new HashMap<String, Character>();

for (char i : myHashMap.keySet()) {
    reversedHashMap.put(myHashMap.get(i), i);
}

stmt.setDate(1, new java.sql.Date(cal.getTime().getTime()));

I had to turn off my personal firewall and Windows firewall as well, and it worked in the end.

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

Here are a few ways of removing a single ' from a string in python.

• str.replace

  replace is usually used to return a string with all the instances of the substring replaced.

  "A single ' char".replace("'","")
  

• str.translate

  In Python 2

  To remove characters you can pass the first argument to the funstion with all the substrings to be removed as second.

  "A single ' char".translate(None,"'")
  

  In Python 3

  You will have to use str.maketrans

  "A single ' char".translate(str.maketrans({"'":None}))
  

• re.sub

  Regular Expressions using re are even more powerful (but slow) and can be used to replace characters that match a particular regex rather than a substring.

  re.sub("'","","A single ' char")
  

Other Ways

There are a few other ways that can be used but are not at all recommended. (Just to learn new ways). Here we have the given string as a variable string.

• Using list comprehension

  ''.join([c for c in string if c != "'"])
  

• Using generator Expression

  ''.join(c for c in string if c != "'")
  

Another final method can be used also (Again not recommended - works only if there is only one occurrence )

• Using list call along with remove and join.

  x = list(string)
  x.remove("'")
  ''.join(x)
  

I always get confused with this, so here is a reminder test case; let's say we have this bash script to test git:

set -x
rm -rf test
mkdir test
cd test
git init
git config user.name test
git config user.email [email protected]
echo 1 > a.txt
echo 1 > b.txt
git add *
git commit -m "initial commit"
echo 2 >> b.txt
git add b.txt
git commit -m "second commit"
echo 3 >> b.txt

At this point, the change is not staged in the cache, so git status is:

$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   b.txt

no changes added to commit (use "git add" and/or "git commit -a")

If from this point, we do git checkout, the result is this:

$ git checkout HEAD -- b.txt
$ git status
On branch master
nothing to commit, working directory clean

If instead we do git reset, the result is:

$ git reset HEAD -- b.txt
Unstaged changes after reset:
M   b.txt
$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   b.txt

no changes added to commit (use "git add" and/or "git commit -a")

So, in this case - if the changes are not staged, git reset makes no difference, while git checkout overwrites the changes.

Now, let's say that the last change from the script above is staged/cached, that is to say we also did git add b.txt at the end.

In this case, git status at this point is:

$ git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    modified:   b.txt

If from this point, we do git checkout, the result is this:

$ git checkout HEAD -- b.txt
$ git status
On branch master
nothing to commit, working directory clean

If instead we do git reset, the result is:

$ git reset HEAD -- b.txt
Unstaged changes after reset:
M   b.txt
$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   b.txt

no changes added to commit (use "git add" and/or "git commit -a")

So, in this case - if the changes are staged, git reset will basically make staged changes into unstaged changes - while git checkout will overwrite the changes completely.

I'm pretty sure those are warnings, not errors. Your project should still run just fine.

However, since you should always try to fix compiler warnings, let's see what we can discover. I'm not at all familiar with OpenCV, and you don't link to the wiki tutorial that you're following. But it looks to me like the problem is that you're running a 64-bit version of Windows (as evidenced by the "SysWOW64" folder in the path to the DLL files), but the OpenCV stuff that you're trying is built for a 32-bit platform. So you might need to rebuild the project using CMake, as explained here.

More specifically, the files that are listed are Windows system files. PDB files contain debugging information that Visual Studio uses to allow you to step into and debug compiled code. You don't actually need the PDB files for system libraries to be able to debug your own code. But if you want, you can download the symbols for the system libraries as well. Go to the "Debug" menu, click on "Options and Settings", and scroll down the listbox on the right until you see "Enable source server support". Make sure that option is checked. Then, in the treeview to the left, click on "Symbols", and make sure that the "Microsoft Symbol Servers" option is selected. Click OK to dismiss the dialog, and then try rebuilding.

To effectively use the typing module (new in Python 3.5) include all (*).

from typing import *

And you will be ready to use:

List, Tuple, Set, Map - for list, tuple, set and map respectively.
Iterable - useful for generators.
Any - when it could be anything.
Union - when it could be anything within a specified set of types, as opposed to Any.
Optional - when it might be None. Shorthand for Union[T, None].
TypeVar - used with generics.
Callable - used primarily for functions, but could be used for other callables.

However, still you can use type names like int, list, dict,...

Personally i think you should learn the hard way first. It will make you a better programmer and you will be able to solve that one of a kind issue when it comes up. After you can do it with pure JavaScript then using jQuery to speed up development is just an added bonus.

If you can do it the hard way then you can do it the easy way, it doesn't work the other way around. That applies to any programming paradigm.

To assign value of a text box whose id is "textbox" in JQuery please do the following

$("#textbox").get(0).value = "blah"

I had this same problem. For me, the reason turned out to be that I had a mismatch in the name of the class and the name of the file. I declared class "GenSig" in a file called "SignatureTester.java".

I changed the name of the class to "SignatureTester", and the "Run as Java Application" option showed up immediately.

SELECT RIGHT('0' 
             + CONVERT(VARCHAR(2), Month( column_name )), 2) 
FROM   table 

You can access rails app path using variable RAILS_ROOT.

For example:

render :file => "#{RAILS_ROOT}/public/layouts/mylayout.html.erb"

In more modern browsers (including IE 10+) you can now use calc():

.moveto {
  top: 0px;
  left: calc(100% - 50px);
}

from pyspark.sql.functions import col

df.select(col("column_name")).collect()

here collect is functions which in turn convert it to list. Be ware of using the list on the huge data set. It will decrease performance. It is good to check the data.

My devices stopped working as Chrome de-activated the now depracated ADB plugin as it's built in dev-tools now.

I downloaded the SDK and followed the instructions at Chrome Developers. How ever I found the instructions served by Alphonso out not to be sufficient and I did it this way on Windows 8:

1. Download Android SDK here ("SDK Tools Only" section) and unzip the content.
2. Run SDK Manager.exe and install Android SDK platform tools
3. Open up the Command prompt (simply by pressing the windows button and type in cmd.exe)
4. Enter the path with ex: cd c:/downloads/sdk/platform-tools
5. Open ADB by typing in adb.exe
6. Run the following command by typing it and pressing enter: adb devices
7. Check if you get the prompt on your device, if you still can't see your phone in Inspect Devices run the following commands one by one (excluding the ") "adb kill-server" "adb start-server" "adb devices"

I had major problems and managed to get it working with these steps. If you still have problems, google the guide Remote Debugging on Android with Chrome and check for the part about drivers. I had problems with my Samsung Galaxy Nexus that needed special drivers to be compatiable with ADB.

Update

If you are using Windows 10 and couldn't find the link to download Android SDK; you may skip #1 and #2. All you need is activate "Android Debug Bridge". Go straight to #3 - #7 after download and execute "platform-tools"(https://developer.android.com/studio/releases/platform-tools.html)

I had the same issue when forking with 'python'; the main reason is that the search path is relative, if you don't call g++ as /usr/bin/g++, it will not be able to work out the canonical paths to call cc1plus.

I tried the solution here to set an environment variable via the command line, but this didn't work. I did this both from a regular command prompt and from the Visual Studio Developer command prompt.

I could overcome this problem like this:

1. go to the Environment variables screen and created a new variable there VS100COMNTOOLS and let it point to my Visual Studio installation folder C:\Program Files\Microsoft Visual Studio 12.0\Common7\Tools\
2. Go to the above folder. Inside this folder there is the file vsvars32.bat. Copy this file and rename it to vsvarsall.bat

My configuration is Visual Studio 2013 (12.0) and Python 3.4.2

SELECT id, user_id, video_name
FROM sa_created_videos
ORDER BY LENGTH(id) ASC, LENGTH(user_id) DESC

In case you use jQuery you need to wait for $(window).load, because the embedded SVG document might not be yet loaded at $(document).ready

$(window).load(function () {

    //alert("Document loaded, including graphics and embedded documents (like SVG)");
    var a = document.getElementById("alphasvg");

    //get the inner DOM of alpha.svg
    var svgDoc = a.contentDocument;

    //get the inner element by id
    var delta = svgDoc.getElementById("delta");
    delta.addEventListener("mousedown", function(){ alert('hello world!')}, false);
});

public static string IntToLetters(int value)
{
string result = string.Empty;
while (--value >= 0)
{
    result = (char)('A' + value % 26 ) + result;
    value /= 26;
}
return result;
}

To meet the requirement of A being 1 instead of 0, I've added -- to the while loop condition, and removed the value-- from the end of the loop, if anyone wants this to be 0 for their own purposes, you can reverse the changes, or simply add value++; at the beginning of the entire method.

git reset --hard 1258f0d0aae

But be careful, if the descendant commits between 1258f0d0aae and HEAD are not referenced in other branches it'll be tedious (but not impossible) to recover them, so you'd better to create a "backup" branch at current HEAD, checkout master, and reset to the commit you want.

Also, be sure that you don't have uncommitted changes before a reset --hard, they will be truly lost (no way to recover).

I always use the return value to pass back error status. If you need to pass back one value I'd use an output parameter.

sample stored procedure, with an OUTPUT parameter:

CREATE PROCEDURE YourStoredProcedure 
(
    @Param1    int
   ,@Param2    varchar(5)
   ,@Param3    datetime OUTPUT
)
AS
IF ISNULL(@Param1,0)>5
BEGIN
    SET @Param3=GETDATE()
END
ELSE
BEGIN
    SET @Param3='1/1/2010'
END
RETURN 0
GO

call to the stored procedure, with an OUTPUT parameter:

DECLARE @OutputParameter  datetime
       ,@ReturnValue      int

EXEC @ReturnValue=YourStoredProcedure 1,null, @OutputParameter OUTPUT
PRINT @ReturnValue
PRINT CONVERT(char(23),@OutputParameter ,121)

OUTPUT:

0
2010-01-01 00:00:00.000

My issue was that the root element actually has a xmlns="abc123"

So had to make XmlRoot("elementname",NameSpace="abc123")

Use a BackgroundWorker. It will allow you to get callbacks on completion and allow you to track progress. You can set the Result value on the event arguments to the resulting value.

    public void UseBackgroundWorker()
    {
        var worker = new BackgroundWorker();
        worker.DoWork += DoWork;
        worker.RunWorkerCompleted += WorkDone;
        worker.RunWorkerAsync("input");
    }

    public void DoWork(object sender, DoWorkEventArgs e)
    {
        e.Result = e.Argument.Equals("input");
        Thread.Sleep(1000);
    }

    public void WorkDone(object sender, RunWorkerCompletedEventArgs e)
    {
        var result = (bool) e.Result;
    }

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

As far as I know, that calculator does not offer mod functions. You can however computer it by hand in a fairly straightforward manner. Ex.

(1)50 mod 3

(2)50/3 = 16.66666667

(3)16.66666667 - 16 = 0.66666667

(4)0.66666667 * 3 = 2

Therefore 50 mod 3 = 2

Things to Note: On line 3, we got the "minus 16" by looking at the result from line (2) and ignoring everything after the decimal. The 3 in line (4) is the same 3 from line (1).

Hope that Helped.

Edit As a result of some trials you may get x.99991 which you will then round up to the number x+1.

As a general rule of thumb, I use 1 cm margins when producing pdfs. I work in the geospatial industry and produce pdf maps that reference a specific geographic scale. Therefore, I do not have the option to 'fit document to printable area,' because this would make the reference scale inaccurate. You must also realize that when you fit to printable area, you are fitting your already existing margins inside the printer margins, so you end up with double margins. Make your margins the right size and your documents will print perfectly. Many modern printers can print with margins less than 3 mm, so 1 cm as a general rule should be sufficient. However, if it is a high profile job, get the specs of the printer you will be printing with and ensure that your margins are adequate. All you need is the brand and model number and you can find spec sheets through a google search.

Fetching data with either null and value on where conditions are very tricky. Even if you are using straight Where and OrWhereNotNull condition then for every rows you will fetch both items ignoring other where conditions if applied. For example if you have more where conditions it will mask out those and still return with either null or value items because you used orWhere condition

The best way so far I found is as follows. This works as where (whereIn Or WhereNotNull)

Code::where(function ($query) {
            $query->where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id');                  
        })->get();

I have a couple of turn-based games where I need the AI to pause before taking its turn (and between steps in its turn). I'm sure there are other, more useful, situations where a delay is the best solution. In Swift:

        let delay = 2.0 * Double(NSEC_PER_SEC) 
        let time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay)) 
        dispatch_after(time, dispatch_get_main_queue()) { self.playerTapped(aiPlayView) }

I just came back here to see if the Objective-C calls were different.(I need to add this to that one, too.)

I updated to Xcode v7.3.1 and it solved the issue.

Divide the Datediff in MS by the number of ms in a day, cast to Datetime, and then to time:

Declare @D1 datetime = '2015-10-21 14:06:22.780', @D2 datetime = '2015-10-21 14:16:16.893'

Select  Convert(time,Convert(Datetime, Datediff(ms,@d1, @d2) / 86400000.0))

Run this comand:

openssl req -x509 -sha256 -nodes -days 3650 -newkey rsa:2048 -keyout app.key -out app.crt  -config openssl.conf

Output files app.crt and app.key work for me.

     @Html.DropDownListFor(m => m.SelectedValue,Your List,"ID","Values")

Here Value is that object of model where you want to save your Selected Value

//the following code checks if your radio button having name like 'yourRadioName' 
//is checked or not
$(document).ready(function() {
  if($("input:radio[name='yourRadioName']").is(":checked")) {

  }
});

and this is the php file to receive the uplaoded files

I found a better library which transform the normal <select> <option> to bootsrap button dropdown format.

https://developer.snapappointments.com/bootstrap-select/

Try this:

Sub GetColumns()

Dim lnRow As Long, lnCol As Long

lnRow = 3 'For testing

lnCol = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="sds", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:=False).Column

End Sub

Probably best not to use colIndex and rowIndex as variable names as they are already mentioned in the Excel Object Library.

Verify by running java --version

Unpack it and place somewhere you can find it. In my example, I will assume you will place it to C:\Selenium\iexploredriver.exe

Then you have to set it up in the system. Here is the Java code pasted from my Selenium project:

File file = new File("C:/Selenium/iexploredriver.exe");
System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver();

Basically, you have to set this property before you initialize driver

Reference:

• Driver executable must be set by the webdriver.ie.driver system property

from __future__ import with_statement
with open('file.txt','r+') as f:
    counter = str(int(f.read().strip())+1)
    f.seek(0)
    f.write(counter)

If you are sending the form with JSON you must remove [] in the sending string. You can do that with the jQuery function serializeObject():

var frm = $(document.myform);
var data = JSON.stringify(frm.serializeObject());

$.fn.serializeObject = function() {
    var o = {};
    //    var a = this.serializeArray();
    $(this).find('input[type="hidden"], input[type="text"], input[type="password"], input[type="checkbox"]:checked, input[type="radio"]:checked, select').each(function() {
        if ($(this).attr('type') == 'hidden') { //if checkbox is checked do not take the hidden field
            var $parent = $(this).parent();
            var $chb = $parent.find('input[type="checkbox"][name="' + this.name.replace(/\[/g, '\[').replace(/\]/g, '\]') + '"]');
            if ($chb != null) {
                if ($chb.prop('checked')) return;
            }
        }
        if (this.name === null || this.name === undefined || this.name === '')
            return;
        var elemValue = null;
        if ($(this).is('select'))
            elemValue = $(this).find('option:selected').val();
        else elemValue = this.value;
        if (o[this.name] !== undefined) {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];
            }
            o[this.name].push(elemValue || '');
        } else {
            o[this.name] = elemValue || '';
        }
    });
    return o;
}

You can try this:

select
  count(distinct tag) as tag_count,
  count(distinct (case when entryId > 0 then tag end)) as positive_tag_count
from
  your_table_name;

The first count(distinct...) is easy. The second one, looks somewhat complex, is actually the same as the first one, except that you use case...when clause. In the case...when clause, you filter only positive values. Zeros or negative values would be evaluated as null and won't be included in count.

One thing to note here is that this can be done by reading the table once. When it seems that you have to read the same table twice or more, it can actually be done by reading once, in most of the time. As a result, it will finish the task a lot faster with less I/O.

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

Yes. You need to use the try/catch block, but no need to catch the Exception. As per the API it will throw NoResultException if there is no result, and its up to you how you want to handle it.

DrawUnusedBalance drawUnusedBalance = null;
try{
drawUnusedBalance = (DrawUnusedBalance)query.getSingleResult()
catch (NoResultException nre){
//Ignore this because as per your logic this is ok!
}

if(drawUnusedBalance == null){
 //Do your logic..
}

This error can happen Tomcat is already running. So make sure Tomcat isn't running in the background if you've asked Intellij to start it up ( default ).

Also, check the full output window for more errors. As a more useful error may have preceded this one ( as was the case with my configuration just now )

The thing you will need to do here is use a linear gradient as background and animate the background position. In code:

Use a linear gradient (50% red, 50% blue) and tell the browser that background is 2 times larger than the element's width (width:200%, height:100%), then tell it to position the background left.

background: linear-gradient(to right, red 50%, blue 50%);
background-size: 200% 100%;
background-position:left bottom;

On hover, change the background position to right bottom and with transition:all 2s ease;, the position will change gradually (it's nicer with linear tough) background-position:right bottom;

http://jsfiddle.net/75Umu/3/

As for the -vendor-prefix'es, see the comments to your question

extra If you wish to have a "transition" in the colour, you can make it 300% width and make the transition start at 34% (a bit more than 1/3) and end at 65% (a bit less than 2/3).

background: linear-gradient(to right, red 34%, blue 65%);
background-size: 300% 100%;

Demo:

div {
    font: 22px Arial;
    display: inline-block;
    padding: 1em 2em;
    text-align: center;
    color: white;
    background: red; /* default color */

    /* "to left" / "to right" - affects initial color */
    background: linear-gradient(to left, salmon 50%, lightblue 50%) right;
    background-size: 200%;
    transition: .5s ease-out;
}
div:hover {
    background-position: left;
}

<div>Hover me</div>

I have found this over here

I found this solution, insert this code at the beginning of your source file:

import ssl

try:
   _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
    pass
else:
    # Handle target environment that doesn't support HTTPS verification
    ssl._create_default_https_context = _create_unverified_https_context

This code makes the verification undone so that the ssl certification is not verified.

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want him to relogin for example) and reset all his session specific data.

Not quite - since each "left" row in a left-outer-join will match 0-n "right" rows (in the second table), where-as yours matches only 0-1. To do a left outer join, you need SelectMany and DefaultIfEmpty, for example:

var query = from c in db.Customers
            join o in db.Orders
               on c.CustomerID equals o.CustomerID into sr
            from x in sr.DefaultIfEmpty()
            select new {
               CustomerID = c.CustomerID, ContactName = c.ContactName,
               OrderID = x == null ? -1 : x.OrderID };   

(or via the extension methods)

Is sku just a property of the Product model? If so:

$products = Product::whereOwnerAndStatus($owner, 0)->take($count)->get();

foreach ($products as $product ) {
  // Access $product->sku here...
}

Or is sku a relationship to another model? If that is the case, then, as long as your relationship is setup properly, you code should work.

SSL development libraries have to be installed

CentOS:

$ yum install openssl-devel libffi-devel

Ubuntu:

$ apt-get install libssl-dev libffi-dev

OS X (with Homebrew installed):

$ brew install openssl

Using multiple threads on CPython won't give you better performance for pure-Python code due to the global interpreter lock (GIL). I suggest using the multiprocessing module instead:

pool = multiprocessing.Pool(4)
out1, out2, out3 = zip(*pool.map(calc_stuff, range(0, 10 * offset, offset)))

Note that this won't work in the interactive interpreter.

To avoid the usual FUD around the GIL: There wouldn't be any advantage to using threads for this example anyway. You want to use processes here, not threads, because they avoid a whole bunch of problems.

SQL Server's TIMESTAMP datatype has nothing to do with a date and time!

It's just a hexadecimal representation of a consecutive 8 byte integer - it's only good for making sure a row hasn't change since it's been read.

You can read off the hexadecimal integer or if you want a BIGINT. As an example:

SELECT CAST (0x0000000017E30D64 AS BIGINT)

The result is

400756068

In newer versions of SQL Server, it's being called RowVersion - since that's really what it is. See the MSDN docs on ROWVERSION:

Is a data type that exposes automatically generated, unique binary numbers within a database. rowversion is generally used as a mechanism for version-stamping table rows. The rowversion data type is just an incrementing number and does not preserve a date or a time. To record a date or time, use a datetime2 data type.

So you cannot convert a SQL Server TIMESTAMP to a date/time - it's just not a date/time.

But if you're saying timestamp but really you mean a DATETIME column - then you can use any of those valid date formats described in the CAST and CONVERT topic in the MSDN help. Those are defined and supported "out of the box" by SQL Server. Anything else is not supported, e.g. you have to do a lot of manual casting and concatenating (not recommended).

The format you're looking for looks a bit like the ODBC canonical (style = 121):

DECLARE @today DATETIME = SYSDATETIME()

SELECT CONVERT(VARCHAR(50), @today, 121)

gives:

2011-11-14 10:29:00.470

SQL Server 2012 will finally have a FORMAT function to do custom formatting......

Just doing like @Kjartan.

Steps are as follows:

1. Right click your C# project name in Visual Studio's "Solution Explorer";

2. Then, select "add -> Reference -> COM -> Type Libraries " in order;

3. Find the "Microsoft Office 16.0 Object Library", and add it to reference (Note: the version number may vary with the OFFICE you have installed);

4. After doing this, you will see "Microsoft.Office.Interop.Word" under the "Reference" item in your project.

You don't appear to have write permission to the /tmp directory on your server. This is a bit weird, but you can work around it. Before the call to session_start() put in a call to session_save_path() and give it the name of a directory writable by the server. Details are here.

BY default permission are not allowing the pem key. You just have to change the permission:

chmod 400 xyz.pem

and if ubuntu instance then connect using:

ssh -i xyz.pem [email protected]

In a second level cache, domain hbm files can be of key mutable and value false. For example, In this domain class some of the duration in a day remains constant as the universal truth. So, it can be marked as immutable across application.

Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.

$products = DB::table('products AS pr')
        ->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
        ->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
        ->orderBy('pr.id', 'desc')
        ->get();

Hope this helps.

For my condition the cause was taking int parameter for TextView. Let me show an example

int i = 5;
myTextView.setText(i);

gets the error info above.

This can be fixed by converting int to String like this

myTextView.setText(String.valueOf(i));

As you write int, it expects a resource not the text that you are writing. So be careful on setting an int as a String in Android.

I like:

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
myDate.ToString(timeFormat)

Easy to maintain if you need to use it in several parts of your code, date formats always seem to change sooner or later.

I solve it just by changing 'http://webname...' to "http://webname..."

Notice the quote. It should be double (") instead of single (').

None of these answers seemed to work for me. They'd get the general location but wouldn't actually pan to the actual place I searched for. Within the .pac-item you can actually get just the address (name of place excluded) by selecting $('.pac-item:first').children()[2].textContent

So here is my solution:

$("#search_field").on("keyup", function(e) {
    if(e.keyCode == 13) {
        searchPlaces();
    }
});

function searchPlaces() {
    var $firstResult = $('.pac-item:first').children();
    var placeName = $firstResult[1].textContent;
    var placeAddress = $firstResult[2].textContent;

    $("#search_field").val(placeName + ", " + placeAddress);

    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({"address":placeAddress }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var lat = results[0].geometry.location.lat(),
                lng = results[0].geometry.location.lng(),
                placeName = results[0].address_components[0].long_name,
                latlng = new google.maps.LatLng(lat, lng);

            map.panTo(latlng);
        }

I know this question was already answered but figured I'd throw in my 2 cents just in case anyone else was having the same problem as me.

  if (e.KeyCode.ToString() == "Return")
  { 
      //do something
  }

My component used an object myClassObject of type MyClass, which itself was using MyEnum. This lead to the same issue described above. Solved it by doing:

export enum MyEnum {
    Option1,
    Option2,
    Option3
}
export class MyClass {
    myEnum: typeof MyEnum;
    myEnumField: MyEnum;
    someOtherField: string;
}

and then using this in the template as

<div [ngSwitch]="myClassObject.myEnumField">
  <div *ngSwitchCase="myClassObject.myEnum.Option1">
    Do something for Option1
  </div>
  <div *ngSwitchCase="myClassObject.myEnum.Option2">
    Do something for Option2
  </div>
  <div *ngSwitchCase="myClassObject.myEnum.Option3">
    Do something for Opiton3
  </div>
</div>

I don't think that you really want an iframe, do you?

Unless you're doing something weird, you should be getting your results back as JSON or (in the worst case) XML, right?

For your white box / extra space issue, try

style="display: none;"

instead of

style="visibility: hidden;"

Remove this from #info:

    margin-left:auto;

Add this for your header:

#info p {
    text-align: center;
}

Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align.

There are apparently distributions or custom builds in which the ability to set Task Tags for non-Java files is not present. This post mentions that ColdFusion Builder (built on Eclipse) does not let you set non-Java Task Tags, but the beta version of CF Builder 2 does. (I know the OP wasn't using CF Builder, but I am, and I was wondering about this question myself ... because he didn't see the ability to set non-Java tags, I thought others might be in the same position.)

Try to do this:

getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setDisplayShowTitleEnabled(false);

and if you made your custom toolbar (which i presume you did) then you can use the simplest way possible to do this:

toolbarTitle = (TextView)findViewById(R.id.toolbar_title);
toolbarSubTitle = (TextView)findViewById(R.id.toolbar_subtitle);
toolbarTitle.setText("Title");
toolbarSubTitle.setText("Subtitle");

Same goes for any other views you put in your toolbar. Hope it helps.

Edit from the future: Please don't use this, this function was removed in Python 3 and Python 2 is dead. Even if you are still using Python 2 you should write Python 3 ready code to make the inevitable upgrade easier.

Although @Burhan Khalid's answer is good, I think it's more understandable like this:

from str import join

sentence = ['this','is','a','sentence']

join(sentence, "-") 

The second argument to join() is optional and defaults to " ".

As others have mentioned, app on Android can't write a file to any folder the internal storage but their own private storage (which is under /data/data/PACKAGE_NAME ).

You should use the API to get the correct path that is allowed for your app.

try this:

puts 'one TWO three foUR'.split.map(&:capitalize).join(' ')

#=> One Two Three Four

or

puts 'one TWO three foUR'.split.map(&:capitalize)*' '

DateTime.AddDays does that:

DateTime expires = yourDate.AddDays(30);

I have written a shell script which will read data from properties file and then run mysql script on shell script. sharing this may help to others.

#!/bin/bash

    function getProperty {
       PROP_KEY=$1
       PROP_VALUE=`cat $PROPERTY_FILE | grep "$PROP_KEY" | cut -d'=' -f2`
       echo $PROP_VALUE
    }

    echo "# Reading property from $PROPERTY_FILE"
    DB_USER=$(getProperty "db.username")
    DB_PASS=$(getProperty "db.password")
    ROOT_LOC=$(getProperty "root.location")
    echo $DB_USER
    echo $DB_PASS
    echo $ROOT_LOC
    echo "Writing on DB ... "
    mysql -u$DB_USER -p$DB_PASS dbname<<EOFMYSQL

    update tablename set tablename.value_ = "$ROOT_LOC" where tablename.name_="Root directory location";
    EOFMYSQL
    echo "Writing root location($ROOT_LOC) is done ... "
    counter=`mysql -u${DB_USER} -p${DB_PASS} dbname -e "select count(*) from tablename where tablename.name_='Root directory location' and tablename.value_ = '$ROOT_LOC';" | grep -v "count"`;

    if [ "$counter" = "1" ]
    then

There are at least two ways for achieving this in base graph (my examples are for the x-axis, but work the same for the y-axis):

1. Use par(xaxp = c(x1, x2, n)) or plot(..., xaxp = c(x1, x2, n)) to define the position (x1 & x2) of the extreme tick marks and the number of intervals between the tick marks (n). Accordingly, n+1 is the number of tick marks drawn. (This works only if you use no logarithmic scale, for the behavior with logarithmic scales see ?par.)

2. You can suppress the drawing of the axis altogether and add the tick marks later with axis().
   To suppress the drawing of the axis use plot(... , xaxt = "n").
   Then call axis() with side, at, and labels: axis(side = 1, at = v1, labels = v2). With side referring to the side of the axis (1 = x-axis, 2 = y-axis), v1 being a vector containing the position of the ticks (e.g., c(1, 3, 5) if your axis ranges from 0 to 6 and you want three marks), and v2 a vector containing the labels for the specified tick marks (must be of same length as v1, e.g., c("group a", "group b", "group c")). See ?axis and my updated answer to a post on stats.stackexchange for an example of this method.

The service :

import 'rxjs/add/operator/map';

import { Http } from '@angular/http';
import { Observable } from "rxjs/Rx"
import { Injectable } from '@angular/core';

@Injectable()
export class ItemService {
  private api = "your_api_url";

  constructor(private http: Http) {

  }

  toSaveItem(item) {
    return new Promise((resolve, reject) => {
      this.http
        .post(this.api + '/items', { item: item })
        .map(res => res.json())
        // This catch is very powerfull, it can catch all errors
        .catch((err: Response) => {
          // The err.statusText is empty if server down (err.type === 3)
          console.log((err.statusText || "Can't join the server."));
          // Really usefull. The app can't catch this in "(err)" closure
          reject((err.statusText || "Can't join the server."));
          // This return is required to compile but unuseable in your app
          return Observable.throw(err);
        })
        // The (err) => {} param on subscribe can't catch server down error so I keep only the catch
        .subscribe(data => { resolve(data) })
    })
  }
}

In the app :

this.itemService.toSaveItem(item).then(
  (res) => { console.log('success', res) },
  (err) => { console.log('error', err) }
)

Starting June 2019, with Windows 10, you won't have to change the codepage.

See "Introducing Windows Terminal" (from Kayla Cinnamon) and the Microsoft/Terminal.
Through the use of the Consolas font, partial Unicode support will be provided.

As documented in Microsoft/Terminal issue 387:

There are 87,887 ideographs currently in Unicode. You need all of them too?
We need a boundary, and characters beyond that boundary should be handled by font fallback / font linking / whatever.

What Consolas should cover:

• Characters that used as symbols that used by modern OSS programs in CLI.
• These characters should follow Consolas' design and metrics, and properly aligned with existing Consolas characters.

What Consolas should NOT cover:

• Characters and punctuation of scripts that beyond Latin, Greek and Cyrillic, especially characters need complex shaping (like Arabic).
• These characters should be handled with font fallback.

window.location.href = window.location.href

You're walking on uncharted territory here. Here is the Go example for calling C code, perhaps you can do something like that after reading up on C++ name mangling and calling conventions, and lots of trial and error.

If you still feel like trying it, good luck.

>>> x = 'it is icy'.replace('i', '', 1)
>>> x
't is icy'

Since your code would only replace the first instance, I assumed that's what you wanted. If you want to replace them all, leave off the 1 argument.

Since you cannot replace the character in the string itself, you have to reassign it back to the variable. (Essentially, you have to update the reference instead of modifying the string.)

I ran into this issue while working on something at work (using React). Basically, we have some external html content that we save into our document table in the database and then insert onto the page under certain circumstances when you're in the Documents dataset.

So, given n inlines, of which up to n could contain external html, we needed to devise a system to automatically resize the iframe of each inline once the content fully loaded in each. After spinning my wheels for a bit, this is how I ended up doing it:

1. Set a message event listener in the index of our React app which checks for a a specific key that we will set from the sender iframe.
2. In the component that actually renders the iframes, after inserting the external html into it, I append a <script> tag that will wait for the iframe's window.onload to fire. Once that fires, we use postMessage to send a message to the parent window with information about the iframe id, computed height, etc.
3. If the origin matches and the key is satisfied in the index listener, grab the DOM id of the iframe that we pass in the MessageEvent object
4. Once we have the iframe, just set the height from the value that is passed from the iframe postMessage.

// index
if (window.postMessage) {
    window.addEventListener("message", (messageEvent) => {
        if (
            messageEvent.data.origin &&
            messageEvent.data.origin === "company-name-iframe"
        ) {
            const iframe = document.getElementById(messageEvent.data.id)
            // this is the only way to ensure that the height of the iframe container matches its body height
            iframe.style.height = `${messageEvent.data.height}px`
            // by default, the iframe will not expand to fill the width of its parent
            iframe.style.width = "100%"
            // the iframe should take precedence over all pointer events of its immediate parent
            // (you can still click around the iframe to segue, for example, but all content of the iframe
            // will act like it has been directly inserted into the DOM)
            iframe.style.pointerEvents = "all"
            // by default, iframes have an ugly web-1.0 border
            iframe.style.border = "none"
        }
    })
}

// in component that renders n iframes
<iframe
    id={`${props.id}-iframe`}
    src={(() => {
        const html = [`data:text/html,${encodeURIComponent(props.thirdLineData)}`]
        if (window.parent.postMessage) {
            html.push(
                `
                <script>
                window.onload = function(event) {
                    window.parent.postMessage(
                        {
                            height: document.body.scrollHeight,
                            id: "${props.id}-iframe",
                            origin: "company-name-iframe",
                        },
                        "${window.location.origin}"
                    );
                };
                </script>
                `
            )
        }

        return html.join("\n")
    })()}
    onLoad={(event) => {
        // if the browser does not enforce a cross-origin policy,
        // then just access the height directly instead
        try {
            const { target } = event
            const contentDocument = (
                target.contentDocument ||
                // Earlier versions of IE or IE8+ where !DOCTYPE is not specified
                target.contentWindow.document
            )
            if (contentDocument) {
                target.style.height = `${contentDocument.body.scrollHeight}px`
            }
        } catch (error) {
            const expectedError = (
                `Blocked a frame with origin "${window.location.origin}" ` +
                `from accessing a cross-origin frame.`
            )
            if (error.message !== expectedError) {

to stop IIS manually:

1. go to start menu
2. type in IIS

you get a search result for the manager (Internet Information Services (IIS) manager, on the right side of it there are restart/stop/start buttons.

If you don't want IIS to start on startup because its really annoying..:

1. go to start menu.
2. click control panel.
3. click programs.
4. turn windows features on or off
5. wait until the list is loaded
6. search for Internet Information Services (IIS).
7. uncheck the box.
8. Wait until it's done with the changes.
9. restart computer, but then again the info box will tell you to do that anyways (you can leave this for later if you want to).

oh and IIS and xampp basically do the same thing just in a bit different way. ANd if you have Xampp for your projects then its not really all that nessecary to leave it on if you don't ever use it anyways.

Beware of the use of push method, if you don't use indexes, it won't work!

var main2dArray: Things[][] = []

main2dArray.push(someTmp1dArray)
main2dArray.push(someOtherTmp1dArray)

gives only a 1 line array!

use

main2dArray[0] = someTmp1dArray
main2dArray[1] = someOtherTmp1dArray

to get your 2d array working!!!

Other beware! foreach doesn't seem to work with 2d arrays!
