ffmpeg -i <input.mp4> -b:v 2048k -s 1000x600 -fs 2048k -vcodec mpeg4 -acodec copy <output.mp4>

• -i input file

• -b:v videobitrate of output video in kilobytes (you have to try)

• -s dimensions of output video

• -fs FILESIZE of output video in kilobytes

• -vcodec videocodec (use ffmpeg -codecs to list all available codecs)

• -acodec audio codec for output video (only copy the audiostream, don't temper)

Other answers describe the purposes. Here are the characters each function will actually convert:

control = '\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C\x0D\x0E\x0F'
        + '\x10\x11\x12\x13\x14\X15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F'
                                                                    + '\x7F'
encodeURI         (control + ' "%<>[\\]^`{|}'                             )
encodeURIComponent(control + ' "%<>[\\]^`{|}' + '#$&,:;=?' + '+/@'        )
escape            (control + ' "%<>[\\]^`{|}' + '#$&,:;=?' +       "!'()~")

All characters above are converted to percent-hexadecimal codes. Space to %20, percent to %25, etc. The characters below pass through unchanged.

Here are the characters the functions will NOT convert:

pass_thru = '*-._0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'

encodeURI         (pass_thru + '#$&,:;=?' + '+/@' + "!'()~")
encodeURIComponent(pass_thru +                      "!'()~")
escape            (pass_thru +              '+/@'          )

Though I can see an accepted answer and other great answers too but thought of sharing what I did to solve this issue (in just one line).

CSS ( Created a Class ) :

.circle {
    border-radius: 50%;
}

HTML (Added that css class to my button) :

<a class="button circle button-energized ion-paper-airplane"></a>

So Easy Right ?

Note : What I actually did was proper use of ionic classes with just one line of css.

I simply wrote an embedded SQL program to write a new record with date fields. It was by far best and shortest without any errors I was able to reach my requirement.

w_dob = %char(%date(*date));      
exec sql insert into Tablename (ID_Number     , 
                             AmendmentNo   , 
                             OverrideDate  , 
                             Operator      , 
                             Text_ID       , 
                             Policy_Company, 
                             Policy_Number , 
                             Override      , 
                             CREATE_USER   ) 
                values ( '801010',    
                            1,            
                           :w_dob,      
                           'MYUSER',     
                            ' ',         
                            '01',        
                            '6535435023150', 
                            '1',         
                            'myuser');    

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

You can't declare a variable as Decimal - you have to use Variant (you can use CDec to populate it with a Decimal type though).

to show which conda env a notebook is using just type in a cell:

!conda info

if you have grep, a more direct way:

!conda info | grep 'active env'

This error can be caused by trying to end a response more than once. As other answers already mentioned, there are various methods that will end a response (like Response.End, or Response.Redirect). If you call more than one in a row, you'll get this error.

I came across this error when I tried to use Response.End after using Response.TransmitFile which seems to end the response too.

I also have same problem and in my case I injected reducer properly but still I couldn't type in field. It turns out if you are using immutable you have to use redux-form/immutable.

import {reducer as formReducer} from 'redux-form/immutable';
const reducer = combineReducers{

    form: formReducer
}
import {Field, reduxForm} from 'redux-form/immutable';
/* your component */

Notice that your state should be like state->form otherwise you have to explicitly config the library also the name for state should be form. see this issue

Databases are heavily optimized for common usage scenarios (and LIKE is one of those).

You won't find a faster way of doing your search if you want to stay on the DB-level.

Given your updated question, these are the simplest forms:

If ProductID is unique you want

SELECT COUNT(*) FROM Products WHERE ProductID IN (1, 10, 100)

and then check that result against 3, the number of products you're querying (this last part can be done in SQL, but it may be easier to do it in C# unless you're doing even more in SQL).

If ProductID is not unique it is

SELECT COUNT(DISTINCT ProductID) FROM Products WHERE ProductID IN (1, 10, 100)

When the question was thought to require returning rows when all ProductIds are present and none otherwise:

SELECT ProductId FROM Products WHERE ProductID IN (1, 10, 100) AND ((SELECT COUNT(*) FROM Products WHERE ProductID IN (1, 10, 100))=3)

or

SELECT ProductId FROM Products WHERE ProductID IN (1, 10, 100) AND ((SELECT COUNT(DISTINCT ProductID) FROM Products WHERE ProductID IN (1, 10, 100))=3)

if you actually intend to do something with the results. Otherwise the simple SELECT 1 WHERE (SELECT ...)=3 will do as other answers have stated or implied.

On Windows, you can run the systeminfo command and retrieves its output for instance with the following code:

private static class WindowsSystemInformation
{
    static String get() throws IOException
    {
        Runtime runtime = Runtime.getRuntime();
        Process process = runtime.exec("systeminfo");
        BufferedReader systemInformationReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

        StringBuilder stringBuilder = new StringBuilder();
        String line;

        while ((line = systemInformationReader.readLine()) != null)
        {
            stringBuilder.append(line);
            stringBuilder.append(System.lineSeparator());
        }

        return stringBuilder.toString().trim();
    }
}

Here's a dictionary that will take any type of key as long as the toString() property returns unique values. The dictionary uses anything as the value for the key value pair.

See Would JavaScript Benefit from a Dictionary Object.

To use the dictionary as is:

var dictFact = new Dict();
var myDict = dictFact.New();
myDict.addOrUpdate("key1", "Value1");
myDict.addOrUpdate("key2", "Value2");
myDict.addOrUpdate("keyN", "ValueN");

The dictionary code is below:

* Holds common object functions. similar to V-Table
* this.New() used to create new dictionary objects

I suspect there is no remote branch named remote-name, but that you've inadvertently created a local branch named origin/remote-name.

Is it possible you at some point typed:

git branch origin/remote-name

Thus creating a local branch named origin/remote-name? Type this command:

git checkout origin/remote-name

You'll either see:

Switched to branch "origin/remote-name"

which means it's really a mis-named local branch, or

Note: moving to "origin/rework-isscoring" which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b 

which means it really is a remote branch.

• If you just want to sort the array values and don't care for the keys, use sort(). This will give a new array with numeric keys starting from 0.
• If you want to keep the key-value associations, use asort().

See also the comparison table of sorting functions in PHP.

=> is used in associative array key value assignment. Take a look at:

http://php.net/manual/en/language.types.array.php.

-> is used to access an object method or property. Example: $obj->method().

When you get this error some annotation is missing. I was missing @service annotation on service. When I added that annotation it worked fine for me.

try

var x = parseFloat(num1) + parseFloat(num2) ;

or, depending on your needs:

var x = parseInt(num1) + parseInt(num2) ;

Here is demo in JSFiddle.

You can also put the files or links into the root of the solution explorer and then set the files properties:

Build action = Content

and

Copy to Output Directory = Copy if newer (for example)

For a link drag the file from the windows explorer into the solution explorer holding down the shift and control keys.

Create the opposite dictionary:

PIX1 = {}
for key in PIX0.keys():
    PIX1[PIX0.get(key)] = key

Then run the same code on this dictionary instead (using PIX1 instead of PIX0).

BTW, I'm not sure about Python 3, but in Python 2 you need to use raw_input instead of input.

If I understand correctly, you want to get the String of an Editable object, right? If yes, try using toString().

@echo off
title Test

echo Select a language. (de/en)
set /p language=

IF /i "%language%"=="de" goto languageDE
IF /i "%language%"=="en" goto languageEN

echo Not found.
goto commonexit

:languageDE
echo German
goto commonexit

:languageEN
echo English
goto commonexit

:commonexit
pause

The point is that batch simply continues through instructions, line by line until it reaches a goto, exit or end-of-file. It has no concept of sections to control flow.

Hence, entering de would jump to :languagede then simply continue executing instructions until the file ends, showing de then en then not found.

You can try to load the child component with history. to do so, pass 'history' through props. Something like that:

  return (
  <div>
    <Login history={this.props.history} />
    <br/>
    <Register/>
  </div>
)

nothing to be done for running your wamp sites to another computer. 1. first turn off the firewall. 2. Set Put Online in wamp by clcking in wamp icon at near to clock.

Finally run your browser in another computer and type http:\ip address or computer name e.g. http:\192.168.1.100

Try these

 String appDirectoryName = getResources().getString(R.string.app_name);
    File directory = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + getResources().getString(R.string.app_name));
    directory.mkdirs();
    File[] fList = directory.listFiles();
    int a = 1;
    for (int x = 0; x < fList.length; x++) {

        //txt.setText("You Have Capture " + String.valueOf(a) + " Photos");
        a++;
    }
    //get all the files from a directory
    for (File file : fList) {
        if (file.isFile()) {
            list.add(new ModelClass(file.getName(), file.getAbsolutePath()));
        }
    }

Considering what @Robert said, I tried to play around with the config command and it seems that there is a direct way to know both the name and email.

To know the username, type:

git config user.name

To know the email, type:

git config user.email

These two output just the name and email respectively and one doesn't need to look through the whole list. Comes in handy.

My solution without JavaScript/images. Only CSS used. It works in all browsers.

HTML:

.add_to_cart {
  cursor:pointer;
  background-color:#EC5500;

There is an example on https://www.redracingparts.com/english/motorbikesmotorcycles/stackoverflow/examples/div/clickable.php

For send parameters in url in POST method You can simply append it to url like this:

$.ajax({
    type: 'POST',
    url: 'superman?' + jQuery.param({ f1: "hello1", f2 : "hello2"}),
    // ...
}); 

The issue you're having is with the type of quantifier. You're using a greedy quantifier in your first group (index 1 - index 0 represents the whole Pattern), which means it'll match as much as it can (and since it's any character, it'll match as many characters as there are in order to fulfill the condition for the next groups).

In short, your 1st group .* matches anything as long as the next group \\d+ can match something (in this case, the last digit).

As per the 3rd group, it will match anything after the last digit.

If you change it to a reluctant quantifier in your 1st group, you'll get the result I suppose you are expecting, that is, the 3000 part.

Note the question mark in the 1st group.

String line = "This order was placed for QT3000! OK?";
Pattern pattern = Pattern.compile("(.*?)(\\d+)(.*)");
Matcher matcher = pattern.matcher(line);
while (matcher.find()) {
    System.out.println("group 1: " + matcher.group(1));
    System.out.println("group 2: " + matcher.group(2));
    System.out.println("group 3: " + matcher.group(3));
}

Output:

group 1: This order was placed for QT
group 2: 3000
group 3: ! OK?

More info on Java Pattern here.

Finally, the capturing groups are delimited by round brackets, and provide a very useful way to use back-references (amongst other things), once your Pattern is matched to the input.

In Java 6 groups can only be referenced by their order (beware of nested groups and the subtlety of ordering).

In Java 7 it's much easier, as you can use named groups.

require_once('db/connect.php');

//rand(1000000 , 9999999);

$products_query = "SELECT id FROM products";
$products_result = mysqli_query($conn, $products_query);
$products_row = mysqli_fetch_array($products_result);
$ids_array = [];

do
{
    array_push($ids_array, $products_row['id']);
}
while($products_row = mysqli_fetch_array($products_result));

/*
echo '<pre>';
print_r($ids_array);
echo '</pre>';
*/
$row_counter = count($ids_array);

for ($i=0; $i < $row_counter; $i++)
{ 
    $current_row = $ids_array[$i];
    $rand = rand(1000000 , 9999999);
    mysqli_query($conn , "UPDATE products SET code='$rand' WHERE id='$current_row'");
}

This will get you the generic link:

selenium.FindElement(By.XPath("xpath=//a[contains(@href,'listDetails.do')")).Click();

If you want to have it specify a parameter then you will have to test for each one:

...
int i = 1;

selenium.FindElement(By.XPath("xpath=//a[contains(@href,'listDetails.do?camp=" + i.ToString() + "')")).Click();
...

The above could utilize a for loop which navigates to and from each camp numbers' page, which could verify a static list of camps.

Please excuse if the code is not perfect, I have not tested myself.

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");

For me, nothing from this list of answers worked.

What finally did the trick is:

1. Performing an uninstall of VS by running the installer with the /uninstall /force command-line options (ref. https://msdn.microsoft.com/en-us/library/mt720585.aspx)
2. Manually renaming all VS14 and nuget related folders from the following places:
   • %AppData%/Local and its sub-folders
   • %AppData%/Roaming and its sub-folders
   • %ProgramData% and its sub-folders
   • %ProgramFiles% and its sub-folders
   • %ProgramFiles(x86)% and its sub-folders
   • %ProgramData%/Package Cache itself
3. Rebooting the machine
4. Installing again.

Yes it is. Use Data Validation from the Data panel. Select Allow: List and pick those cells on the other sheet as your source.

200 (cache) means Firefox is simply using the locally cached version. This is the fastest because no request to the Web server is made.

304 means Firefox is sending a "If-Modified-Since" conditional request to the Web server. If the file has not been updated since the date sent by the browser, the Web server returns a 304 response which essentially tells Firefox to use its cached version. It is not as fast as 200 (cache) because the request is still sent to the Web server, but the server doesn't have to send the contents of the file.

To your last question, I don't know why the two JavaScript files in the same directory are returning different results.

As Luiggi mentioned you need to change your main to:

import java.util.Arrays;

public class trial1{

    public static void main(String[] args){
        int[] A = numbers();
        System.out.println(Arrays.toString(A)); //Might require import of util.Arrays
    }

    public static int[] numbers(){
        int[] A = {1,2,3};
        return A;
    }
}

You can use contains (this works with an arbitrary sequence):

df.filter($"foo".contains("bar"))

like (SQL like with SQL simple regular expression whith _ matching an arbitrary character and % matching an arbitrary sequence):

df.filter($"foo".like("bar"))

or rlike (like with Java regular expressions):

df.filter($"foo".rlike("bar"))

depending on your requirements. LIKE and RLIKE should work with SQL expressions as well.

Driver for Huawei was not found. So I've been using the universal ADB driver:

• Download this:
• Extract ADBDriverInstaller and Run the file. Make sure you have connected your device through USB to your computer.
• A window is displayed.
• Click Install.
• A dialog box will appear. It will ask you to press the Restart button.

Before doing that read this link:

(The above. in brief, says to press Restart button in the dialog box. Select Troubleshoot. Select Advance Option. Select Startup Setting. Press Restart. After system's been restarted, on the appearing screen press 7)

• When PC has been Restarted, Run the ADBDriverInstaller file again. Select your device from the options. Press install.

And it's done :)

Actually now you can use generics in Python 3.5+. See PEP-484 and typing module documentation.

According to my practice it is not very seamless and clear especially for those who are familiar with Java Generics, but still usable.

You can use the selected attribute for the option element to select a choice by default. You can use the required attribute for the select element to ensure that the user selects something.

In Javascript, you can check the selectedIndex property to get the index of the selected option, or you can check the value property to get the value of the selected option.

According to the HTML5 spec, selectedIndex "returns the index of the first selected item, if any, or -1 if there is no selected item. And value "returns the value of the first selected item, if any, or the empty string if there is no selected item." So if selectedIndex = -1, then you know they haven't selected anything.

<button type="button" onclick="displaySelection()">What did I pick?</button>
<script>
    function displaySelection()
    {
        var mySelect = document.getElementById("someSelectElement");
        var mySelection = mySelect.selectedIndex;
        alert(mySelection);
    }
</script>

Yes, I'm answering my own question, but I haven't found it here yet and thought this was a rather slick thing:

...in VB.NET:

String.Join(",", CType(TargetArrayList.ToArray(Type.GetType("System.String")), String()))

...in C#

string.Join(",", (string[])TargetArrayList.ToArray(Type.GetType("System.String")))

The only "gotcha" to these is that the ArrayList must have the items stored as Strings if you're using Option Strict to make sure the conversion takes place properly.

EDIT: If you're using .net 2.0 or above, simply create a List(Of String) type object and you can get what you need with. Many thanks to Joel for bringing this up!

String.Join(",", TargetList.ToArray())

Supplemental answer

Given an OnTouchListener

private View.OnTouchListener handleTouch = new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        int x = (int) event.getX();
        int y = (int) event.getY();

        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                Log.i("TAG", "touched down");
                break;
            case MotionEvent.ACTION_MOVE:
                Log.i("TAG", "moving: (" + x + ", " + y + ")");
                break;
            case MotionEvent.ACTION_UP:
                Log.i("TAG", "touched up");
                break;
        }

        return true;
    }
};

set on some view:

myView.setOnTouchListener(handleTouch);

This gives you the touch event coordinates relative to the view that has the touch listener assigned to it. The top left corner of the view is (0, 0). If you move your finger above the view, then y will be negative. If you move your finger left of the view, then x will be negative.

int x = (int)event.getX();
int y = (int)event.getY();

If you want the coordinates relative to the top left corner of the device screen, then use the raw values.

int x = (int)event.getRawX();
int y = (int)event.getRawY();

You have mixed 2 standard.

The function http_build_query($filedata) is only for "Content-Type: application/x-www-form-urlencoded", or none.

Some short background:

Unfortunately the Unix API doesn't provide a running program with the full path to the executable. In fact, the program executing yours can provide whatever it wants in the field that normally tells your program what it is. There are, as all the answers point out, various heuristics for finding likely candidates. But nothing short of searching the entire filesystem will always work, and even that will fail if the executable is moved or removed.

But you don't want the Perl executable, which is what's actually running, but the script it is executing. And Perl needs to know where the script is to find it. It stores this in __FILE__, while $0 is from the Unix API. This can still be a relative path, so take Mark's suggestion and canonize it with File::Spec->rel2abs( __FILE__ );

1) To get the reason text if you only have the code, you can use:

org.apache.http.impl.EnglishReasonPhraseCatalog.INSTANCE.getReason(httpCode,null)

Where httpCode would be the reason code that you got from the HTTP response.

See https://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/impl/EnglishReasonPhraseCatalog.html for details

2) To get the reason code if you only have the text, you can use BasicHttpResponse.

The dot itself is not an operator, .^ is.

The .^ is a pointwise¹ (i.e. element-wise) power, as .* is the pointwise product.

.^ Array power. A.^B is the matrix with elements A(i,j) to the B(i,j) power. The sizes of A and B must be the same or be compatible.

If you want to stick to an array then this way you can make use. But its not good as compared to List and not recommended. However it will solve your problem.

        int[] list;
        String st;
        String[] stNew;
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter Numbers: "); // If user enters 5 6 7 8 9 
        st = scan.nextLine();
        stNew = st.split("\\s+");
        list = new int[stNew.length]; // Sets array size to 5

        for (int i = 0; i < stNew.length; i++){
            list[i] =  Integer.parseInt(stNew[i]);
            System.out.println("You Enterred: " + list[i]);
        }
    }
}

Commenting on Ken Bertelson solution and answering Jan Hettich:

How it works

the takes_ary_as_arg descTable[@] optsTable[@] line in try_with_local_arys() function sends:

1. This is actually creates a copy of the descTable and optsTable arrays which are accessible to the takes_ary_as_arg function.
2. takes_ary_as_arg() function receives descTable[@] and optsTable[@] as strings, that means $1 == descTable[@] and $2 == optsTable[@].

3. in the beginning of takes_ary_as_arg() function it uses ${!parameter} syntax, which is called indirect reference or sometimes double referenced, this means that instead of using $1's value, we use the value of the expanded value of $1, example:

   baba=booba
   variable=baba
   echo ${variable} # baba
   echo ${!variable} # booba
   

   likewise for $2.

4. putting this in argAry1=("${!1}") creates argAry1 as an array (the brackets following =) with the expanded descTable[@], just like writing there argAry1=("${descTable[@]}") directly. the declare there is not required.

N.B.: It is worth mentioning that array initialization using this bracket form initializes the new array according to the IFS or Internal Field Separator which is by default tab, newline and space. in that case, since it used [@] notation each element is seen by itself as if he was quoted (contrary to [*]).

My reservation with it

In BASH, local variable scope is the current function and every child function called from it, this translates to the fact that takes_ary_as_arg() function "sees" those descTable[@] and optsTable[@] arrays, thus it is working (see above explanation).

Being that case, why not directly look at those variables themselves? It is just like writing there:

argAry1=("${descTable[@]}")

See above explanation, which just copies descTable[@] array's values according to the current IFS.

In summary

This is passing, in essence, nothing by value - as usual.

I also want to emphasize Dennis Williamson comment above: sparse arrays (arrays without all the keys defines - with "holes" in them) will not work as expected - we would loose the keys and "condense" the array.

That being said, I do see the value for generalization, functions thus can get the arrays (or copies) without knowing the names:

• for ~"copies": this technique is good enough, just need to keep aware, that the indices (keys) are gone.

• for real copies: we can use an eval for the keys, for example:

  eval local keys=(\${!$1})
  

and then a loop using them to create a copy. Note: here ! is not used it's previous indirect/double evaluation, but rather in array context it returns the array indices (keys).

• and, of course, if we were to pass descTable and optsTable strings (without [@]), we could use the array itself (as in by reference) with eval. for a generic function that accepts arrays.

In a ScrollView this doesn't work, as the RelativeLayout would then overlap whatever is in the ScrollView at the bottom of the page.

I fixed it using a dynamically stretching FrameLayout :

<ScrollView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="match_parent" 
    android:layout_width="match_parent"
    android:fillViewport="true">
    <LinearLayout 
        android:id="@+id/LinearLayout01"
        android:layout_width="match_parent" 
        android:layout_height="match_parent"
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical">

                <!-- content goes here -->

                <!-- stretching frame layout, using layout_weight -->
        <FrameLayout
            android:layout_width="match_parent" 
            android:layout_height="0dp"
            android:layout_weight="1">
        </FrameLayout>

                <!-- content fixated to the bottom of the screen -->
        <LinearLayout 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content"
            android:orientation="horizontal">
                                   <!-- your bottom content -->
        </LinearLayout>
    </LinearLayout>
</ScrollView>

For me the problem was nothing to do with Maven but to do with how I was running the .jar. I wrote some code and packaged it as a .jar with Maven. I ran it with

java target/gs-maven-0.1.0.jar

and got the error in the OP. Actually you need the -jar option:

java -jar target/gs-maven-0.1.0.jar

You're misunderstanding the meaning of the merge here.

The --no-commit prevents the MERGE COMMIT from occuring, and that only happens when you merge two divergent branch histories; in your example that's not the case since Git indicates that it was a "fast-forward" merge and then Git only applies the commits already present on the branch sequentially.

for i in *.xls ; do 
  [[ -f "$i" ]] || continue
  xls2csv "$i" "${i%.xls}.csv"
done

The first line in the do checks if the "matching" file really exists, because in case nothing matches in your for, the do will be executed with "*.xls" as $i. This could be horrible for your xls2csv.

This should be faster than iterating and will work regardless of shape.

numpy.isnan(myarray).any()

Edit: 30x faster:

import timeit
s = 'import numpy;a = numpy.arange(10000.).reshape((100,100));a[10,10]=numpy.nan'
ms = [
    'numpy.isnan(a).any()',
    'any(numpy.isnan(x) for x in a.flatten())']
for m in ms:
    print "  %.2f s" % timeit.Timer(m, s).timeit(1000), m

Results:

  0.11 s numpy.isnan(a).any()
  3.75 s any(numpy.isnan(x) for x in a.flatten())

Bonus: it works fine for non-array NumPy types:

>>> a = numpy.float64(42.)
>>> numpy.isnan(a).any()
False
>>> a = numpy.float64(numpy.nan)
>>> numpy.isnan(a).any()
True

The answer by Nils describes how to convert objects to maps, which I found very useful. However, the OP was also wondering where this information is in the MDN docs. While it may not have been there when the question was originally asked, it is now on the MDN page for Object.entries() under the heading Converting an Object to a Map which states:

Converting an Object to a Map

The new Map() constructor accepts an iterable of entries. With Object.entries, you can easily convert from Object to Map:

const obj = { foo: 'bar', baz: 42 }; 
const map = new Map(Object.entries(obj));
console.log(map); // Map { foo: "bar", baz: 42 }

another nice recursive way to generate HTML from a nested JSON object (currently not supporting arrays):

// generate HTML code for an object
var make_table = function(json, css_class='tbl_calss', tabs=1){
    // helper to tabulate the HTML tags. will return '\t\t\t' for num_of_tabs=3
    var tab = function(num_of_tabs){
        var s = '';
        for (var i=0; i<num_of_tabs; i++){
            s += '\t';
        }
        //console.log('tabbing done. tabs=' + tabs)
        return s;
    }
    // recursive function that returns a fixed block of <td>......</td>.
    var generate_td = function(json){ 
        if (!(typeof(json) == 'object')){
            // for primitive data - direct wrap in <td>...</td>
            return tab(tabs) + '<td>'+json+'</td>\n';
        }else{
            // recursive call for objects to open a new sub-table inside the <td>...</td>
            // (object[key] may be also an object)
            var s = tab(++tabs)+'<td>\n';
            s +=        tab(++tabs)+'<table class="'+css_class+'">\n';
            for (var k in json){
                s +=        tab(++tabs)+'<tr>\n';
                s +=          tab(++tabs)+'<td>' + k + '</td>\n';
                s +=                      generate_td(json[k]);
                s +=        tab(--tabs)+'</tr>' + tab(--tabs) + '\n';


            }
            // close the <td>...</td> external block
            s +=        tab(tabs--)+'</table>\n';
            s +=    tab(tabs--)+'</td>\n';
            return s;
        }
    }
    // construct the complete HTML code
    var html_code = '' ;
    html_code += tab(++tabs)+'<table class="'+css_class+'">\n';
    html_code +=   tab(++tabs)+'<tr>\n';
    html_code +=     generate_td(json);
    html_code +=   tab(tabs--)+'</tr>\n';
    html_code += tab(tabs--)+'</table>\n';
    return html_code;
}

Quick Description of AJAX

AJAX is simply Asyncronous JSON or XML (in most newer situations JSON). Because we are doing an ASYNC task we will likely be providing our users with a more enjoyable UI experience. In this specific case we are doing a FORM submission using AJAX.

Really quickly there are 4 general web actions GET, POST, PUT, and DELETE; these directly correspond with SELECT/Retreiving DATA, INSERTING DATA, UPDATING/UPSERTING DATA, and DELETING DATA. A default HTML/ASP.Net webform/PHP/Python or any other form action is to "submit" which is a POST action. Because of this the below will all describe doing a POST. Sometimes however with http you might want a different action and would likely want to utilitize .ajax.

My code specifically for you (described in code comments):

/* attach a submit handler to the form */
$("#formoid").submit(function(event) {

  /* stop form from submitting normally */
  event.preventDefault();

  /* get the action attribute from the <form action=""> element */
  var $form = $(this),
    url = $form.attr('action');

  /* Send the data using post with element id name and name2*/
  var posting = $.post(url, {
    name: $('#name').val(),
    name2: $('#name2').val()
  });

  /* Alerts the results */
  posting.done(function(data) {
    $('#result').text('success');
  });
  posting.fail(function() {
    $('#result').text('failed');
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<form id="formoid" action="studentFormInsert.php" title="" method="post">
  <div>
    <label class="title">First Name</label>
    <input type="text" id="name" name="name">
  </div>
  <div>
    <label class="title">Last Name</label>
    <input type="text" id="name2" name="name2">
  </div>
  <div>
    <input type="submit" id="submitButton" name="submitButton" value="Submit">
  </div>
</form>

<div id="result"></div>

Documentation

From jQuery website $.post documentation.

Example: Send form data using ajax requests

$.post("test.php", $("#testform").serialize());

Example: Post a form using ajax and put results in a div

<!DOCTYPE html>
<html>
    <head>
        <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
    </head>
    <body>
        <form action="/" id="searchForm">
            <input type="text" name="s" placeholder="Search..." />
            <input type="submit" value="Search" />
        </form>
        <!-- the result of the search will be rendered inside this div -->
        <div id="result"></div>
        <script>
            /* attach a submit handler to the form */
            $("#searchForm").submit(function(event) {

                /* stop form from submitting normally */
                event.preventDefault();

                /* get some values from elements on the page: */
                var $form = $(this),
                    term = $form.find('input[name="s"]').val(),
                    url = $form.attr('action');

                /* Send the data using post */
                var posting = $.post(url, {
                    s: term
                });

                /* Put the results in a div */
                posting.done(function(data) {
                    var content = $(data).find('#content');
                    $("#result").empty().append(content);
                });
            });
        </script>
    </body>

TypeScript supports decorators, and using that feature plus a little library called typescript-mix you can use mixins to have multiple inheritance with just a couple of lines

// The following line is only for intellisense to work
interface Shopperholic extends Buyer, Transportable {}

class Shopperholic {
  // The following line is where we "extend" from other 2 classes
  @use( Buyer, Transportable ) this 
  price = 2000;
}

Dokan looks like a FUSE and sshfs implementation for Windows. If it works as expected and advertised, it would do exactly what you are looking for.

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

It's been a while since I C++'d but these answers are off a bit.

As far as the size goes, 'int' isn't anything. It's a notional value of a standard integer; assumed to be fast for purposes of things like iteration. It doesn't have a preset size.

So, the answers are correct with respect to the differences between int and uint, but are incorrect when they talk about "how large they are" or what their range is. That size is undefined, or more accurately, it will change with the compiler and platform.

It's never polite to discuss the size of your bits in public.

When you compile a program, int does have a size, as you've taken the abstract C/C++ and turned it into concrete machine code.

So, TODAY, practically speaking with most common compilers, they are correct. But do not assume this.

Specifically: if you're writing a 32 bit program, int will be one thing, 64 bit, it can be different, and 16 bit is different. I've gone through all three and briefly looked at 6502 shudder

A brief google search shows this: https://www.tutorialspoint.com/cprogramming/c_data_types.htm This is also good info: https://docs.oracle.com/cd/E19620-01/805-3024/lp64-1/index.html

use int if you really don't care how large your bits are; it can change.

Use size_t and ssize_t if you want to know how large something is.

If you're reading or writing binary data, don't use int. Use a (usually platform/source dependent) specific keyword. WinSDK has plenty of good, maintainable examples of this. Other platforms do too.

I've spent a LOT of time going through code from people that "SMH" at the idea that this is all just academic/pedantic. These ate the people that write unmaintainable code. Sure, it's easy to use type 'int' and use it without all the extra darn typing. It's a lot of work to figure out what they really meant, and a bit mind-numbing.

It's crappy coding when you mix int.

use int and uint when you just want a fast integer and don't care about the range (other than signed/unsigned).

This code snippet is working properly

CSS in emails is a pain. You'll probably need tables unfortunately, because CSS is not greatly supported in all email clients.

That said, use an HTML Transitional DOCTYPE, not XHTML, and use <center>.

To answer your question, yes. The other have answered that part, but it also seems like you're asking if that's the best way to do it.

It would probably depend on what you are doing. Typically you would have a user click what items they want to buy (ordering for example). Then they would hit a buy or checkout button. Then the form would send off to a page and process the result. You could do all of that with a cookie but I would find it to be more difficult.

You may want to consider posting your second question in another topic.

<CheckBox
      android:id="@+id/checkBox1"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Fees Paid Rs100:"
      android:textColor="#276ca4"
      android:checked="false"
      android:onClick="checkbox_clicked" />

Main Activity from here

   public class RegistA extends Activity {
CheckBox fee_checkbox;
 @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_regist);
 fee_checkbox = (CheckBox)findViewById(R.id.checkBox1);// Fee Payment Check box
}

checkbox clicked

     public void checkbox_clicked(View v)
     {

         if(fee_checkbox.isChecked())
         {
            // true,do the task 

         }
         else
         {

         }

     }

In addition to Eric Leschinski's answer, and because this is stackoverflow, a programmatical solution:

Windows uses hidden file forks to mark content as "downloaded". Truncating these unblocks the file. The name of the stream used for CHM's is "Zone.Identifier". One can access streams by appending :streamname when opening the file. (keep backups the first time, in case your RTL messes that up!)

In Delphi it would look like this:

var f : file;
begin
 writeln('unblocking ',s);
 assignfile(f,'some.chm:Zone.Identifier');
 rewrite(f,1);
 truncate(f);
 closefile(f);
end;

I'm told that on non forked filesystems (like FAT32) there are hidden files, but I haven't gotten to the bottom of that yet.

P.s. Delphi's DeleteFile() should also recognize forks.

Gradle put the fun back into building/assembling software. I used ant to build software my entire career and I have always considered the actual "buildit" part of the dev work being a necessary evil. A few months back our company grew tired of not using a binary repo (aka checking in jars into the vcs) and I was given the task to investigate this. Started with ivy since it could be bolted on top of ant, didn't have much luck getting my built artifacts published like I wanted. I went for maven and hacked away with xml, worked splendid for some simple helper libs but I ran into serious problems trying to bundle applications ready for deploy. Hassled quite a while googling plugins and reading forums and wound up downloading trillions of support jars for various plugins which I had a hard time using. Finally I went for gradle (getting quite bitter at this point, and annoyed that "It shouldn't be THIS hard!")

But from day one my mood started to improve. I was getting somewhere. Took me like two hours to migrate my first ant module and the build file was basically nothing. Easily fitted one screen. The big "wow" was: build scripts in xml, how stupid is that? the fact that declaring one dependency takes ONE row is very appealing to me -> you can easily see all dependencies for a certain project on one page. From then on I been on a constant roll, for every problem I faced so far there is a simple and elegant solution. I think these are the reasons:

• groovy is very intuitive for java developers
• documentation is great to awesome
• the flexibility is endless

Now I spend my days trying to think up new features to add to our build process. How sick is that?

The Reason is that your previous build is still running in the background. I solve this problem by following these steps:

• Open Task Manager
• Goto Details Tab
• Find Your Application
• End Task it by right clicking on it
• Done!

Some time has passed since most of these answers have been posted and some use now deprecated methods and constants.

I've updated Jarek's code to not use these methods and constants anymore:

protected int getScreenOrientation()
{
    Display getOrient = getWindowManager().getDefaultDisplay();
    Point size = new Point();

    getOrient.getSize(size);

    int orientation;
    if (size.x < size.y)
    {
        orientation = Configuration.ORIENTATION_PORTRAIT;
    }
    else
    {
        orientation = Configuration.ORIENTATION_LANDSCAPE;
    }
    return orientation;
}

Note that the mode Configuration.ORIENTATION_SQUARE isn't supported anymore.

I found this to be reliable on all devices I've tested it on in contrast to the method suggesting the usage of getResources().getConfiguration().orientation

The lock screen works without keyguard i have tested it. The home button stops working and you can't get to task manager by holding the home key. I wish they didn't develop a new process when it used to be built into system ui or whatever. I don't see the need for the change and extra process

Yarn

I had the problem when running: yarn start

It was fixed with running first: yarn install

phpPgAdmin might work for you, if you're already familiar with phpMyAdmin.

Please note that development of phpPgAdmin has moved to github per this notice but the SourceForge link above is for historical / documentation purposes.

But really there are dozens of tools that can do this.

To mark a lambda async, simply prepend async before its argument list:

// Add a command to delete the current Group
contextMenu.Commands.Add(new UICommand("Delete this Group", async (contextMenuCmd) =>
{
    SQLiteUtils slu = new SQLiteUtils();
    await slu.DeleteGroupAsync(groupName);
}));

I recently spent a week studying lot of solutions to validate my forms in an app. I started with all the most stared one but I couldn't find one who was working as I was expected. After few days, I became quite frustrated until i found a very new and amazing plugin: https://github.com/kettanaito/react-advanced-form

The developper is very responsive and his solution, after my research, merit to become the most stared one from my perspective. I hope it could help and you'll appreciate.

thisReader.GetString(int columnIndex)

One issue with the other examples is they multiply the input value before dividing it. There is an edge case here that you can overflow decimal by multiplying first, an edge case, but something I have come across. It's safer to deal with the fractional part separately as follows:

    public static decimal TruncateDecimal(this decimal value, int decimalPlaces)
    {
        decimal integralValue = Math.Truncate(value);

        decimal fraction = value - integralValue;

        decimal factor = (decimal)Math.Pow(10, decimalPlaces);

        decimal truncatedFraction = Math.Truncate(fraction * factor) / factor;

        decimal result = integralValue + truncatedFraction;

        return result;
    }

Thank you @Gorge Reith. Working off the solution provided by @George Reith, here is a function that furthers (1) separates out the individual 'hrefs' links (because they might be useful), (2) uses attributes as keys (since attributes are more descriptive), and (3) it's usable within Node.js without needing Chrome by using the 'jsdom' package:

const jsdom = require('jsdom') // npm install jsdom provides in-built Window.js without needing Chrome


// Function to map HTML DOM attributes to inner text and hrefs
function mapDOM(html_string, json) {
    treeObject = {}

    // IMPT: use jsdom because of in-built Window.js
    // DOMParser() does not provide client-side window for element access if coding in Nodejs
    dom = new jsdom.JSDOM(html_string)
    document = dom.window.document
    element = document.firstChild

    // Recursively loop through DOM elements and assign attributes to inner text object
    // Why attributes instead of elements? 1. attributes more descriptive, 2. usually important and lesser
    function treeHTML(element, object) {
        var nodeList = element.childNodes;
        if (nodeList != null) {
           if (nodeList.length) {
               object[element.nodeName] = []  // IMPT: empty [] array for non-text recursivable elements (see below)
               for (var i = 0; i < nodeList.length; i++) {
                   // if final text
                   if (nodeList[i].nodeType == 3) {
                       if (element.attributes != null) {
                           for (var j = 0; j < element.attributes.length; j++) {
                                if (element.attributes[j].nodeValue !== '' && 
                                    nodeList[i].nodeValue !== '') {
                                    if (element.attributes[j].name === 'href') { // separate href
                                        object[element.attributes[j].name] = element.attributes[j].nodeValue;
                                    } else {
                                        object[element.attributes[j].nodeValue] = nodeList[i].nodeValue;
                                    }

                                }
                           }
                       }
                   // else if non-text then recurse on recursivable elements
                   } else {
                       object[element.nodeName].push({}); // if non-text push {} into empty [] array
                       treeHTML(nodeList[i], object[element.nodeName][object[element.nodeName].length -1]);
                   }
               }
           }
        }
    }
    treeHTML(element, treeObject);

    return (json) ? JSON.stringify(treeObject) : treeObject;
}

JavaScript 1.2 was introduced with Netscape Navigator 4 in 1997. That version number only ever had significance for Netscape browsers. For example, Microsoft's implementation (as used in Internet Explorer) is called JScript, and has its own version numbering which bears no relation to Netscape's numbering.

if you are using Java 8, try this

Arrays.stream(e.getStackTrace())
                .map(s->s.toString())
                .collect(Collectors.joining("\n"));

you can find the code for getStackTrace() function provided by Throwable.java as :

public StackTraceElement[] getStackTrace() {
    return getOurStackTrace().clone();
}

and for StackTraceElement, it provides toString() as follows:

public String toString() {
    return getClassName() + "." + methodName +
        (isNativeMethod() ? "(Native Method)" :
         (fileName != null && lineNumber >= 0 ?
          "(" + fileName + ":" + lineNumber + ")" :
          (fileName != null ?  "("+fileName+")" : "(Unknown Source)")));
}

So just join the StackTraceElement with "\n".

Like mentioned earlier, I'd recommend boost lexical_cast. Not only does it have a fairly nice syntax:

#include <boost/lexical_cast.hpp>
std::string s = boost::lexical_cast<std::string>(i);

it also provides some safety:

try{
  std::string s = boost::lexical_cast<std::string>(i);
}catch(boost::bad_lexical_cast &){
 ...
}

I would suggest a slight change in your logic. It may or may not work, depending on what you need to accomplish.

handle_event() can still do the "boring default code" but instead of being virtual, at the point where you want it to do the "new exciting code" have the base class call an abstract method (i.e. must-be-overridden) method that will be supplied by your descendant class.

EDIT: And if you later decide that some of your descendant classes do not need to provide "new exciting code" then you can change the abstract to virtual and supply an empty base class implementation of that "inserted" functionality.

function getMethods(obj)
{
    var res = [];
    for(var m in obj) {
        if(typeof obj[m] == "function") {
            res.push(m)
        }
    }
    return res;
}

Have a look at the timeit module. It's not really equivalent but if the code you want to time is inside a function you can easily use it.

I had the same problem and solved it by using the default woocommerce hook to display the product image.

while ( $loop->have_posts() ) : $loop->the_post();
   echo woocommerce_get_product_thumbnail('woocommerce_full_size');
endwhile;

Available parameters:

• woocommerce_thumbnail
• woocommerce_full_size

All the other response are very miss-leading for somebody coming from google and looking for "timestamp in go"! YYYYMMDDhhmmss is not a "timestamp".

To get the "timestamp" of a date in go (number of seconds from january 1970), the correct function is .Unix(), and it really return an integer

Code & detects ctrl+z

document.onkeyup = function(e) {
  if(e.ctrlKey && e.keyCode == 90) {
    // ctrl+z pressed
  }
}

You can use the split() function, which returns a list, to separate them.

letters = 'QH QD JC KD JS'

letters_list = letters.split()

Printing letters_list would now format it like this:

['QH', 'QD', 'JC', 'KD', 'JS']

Now you have a list that you can work with, just like you would with any other list. For example accessing elements based on indexes:

print(letters_list[2])

This would print the third element of your list, which is 'JC'

SET STATISTICS TIME ON

SELECT * 

FROM Production.ProductCostHistory
WHERE StandardCost < 500.00;

SET STATISTICS TIME OFF;

And see the message tab it will look like this:

SQL Server Execution Times:

   CPU time = 0 ms,  elapsed time = 10 ms.

(778 row(s) affected)

SQL Server parse and compile time: 

   CPU time = 0 ms, elapsed time = 0 ms.

I don't know how much Scala style has changed in the past 9 years, but I found it interesting that most of the existing answers use vars, or hard to read recursion. The key to exiting early is to use a lazy collection to generate your possible candidates, then check for the condition separately. To generate the products:

val products = for {
  i <- (999 to 1 by -1).view
  j <- (i to 1 by -1).view
} yield (i*j)

Then to find the first palindrome from that view without generating every combination:

val palindromes = products filter {p => p.toString == p.toString.reverse}
palindromes.head

To find the largest palindrome (although the laziness doesn't buy you much because you have to check the entire list anyway):

palindromes.max

Your original code is actually checking for the first palindrome that is larger than a subsequent product, which is the same as checking for the first palindrome except in a weird boundary condition which I don't think you intended. The products are not strictly monotonically decreasing. For example, 998*998 is greater than 999*997, but appears much later in the loops.

Anyway, the advantage of the separated lazy generation and condition check is you write it pretty much like it is using the entire list, but it only generates as much as you need. You sort of get the best of both worlds.

You need to install ssh2 lib

sudo apt-get install libssh2-php && sudo /etc/init.d/apache2 restart

that should be enough to get you on the road

There are two ways. the first is to completely refresh the page using typical form submission

//your_page.php

<?php 

$saveSuccess = null;
$saveMessage = null;

if($_SERVER['REQUEST_METHOD'] == 'POST') {
  // if form has been posted process data

  // you dont need the addContact function you jsut need to put it in a new array
  // and it doesnt make sense in this context so jsut do it here
  // then used json_decode and json_decode to read/save your json in
  // saveContact()
  $data = array(
    'fullname' = $_POST['fullname'],
    'email' => $_POST['email'],
    'phone' => $_POST['phone']
  );

  // always return true if you save the contact data ok or false if it fails
  if(($saveSuccess = saveContact($data)) {
     $saveMessage = 'Your submission has been saved!';     
  } else {
     $saveMessage = 'There was a problem saving your submission.';
  } 
}
?>

<!-- your other html -->

<?php if($saveSuccess !== null): ?>
   <p class="flash_message"><?php echo $saveMessage ?></p>
<?php endif; ?>

<form action="your_page.php" method="post">
    <fieldset>
        <legend>Add New Contact</legend>
        <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
        <input type="email" name="email" placeholder="[email protected]" required /> <br />
        <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
        <input type="submit" name="submit" class="button" value="Add Contact" onClick="" />
        <input type="button" name="cancel" class="button" value="Reset" />
    </fieldset>
</form>

<!-- the rest of your HTML -->

The second way would be to use AJAX. to do that youll want to completely seprate the form processing into a separate file:

// process.php

$response = array();

if($_SERVER['REQUEST_METHOD'] == 'POST') {
  // if form has been posted process data

  // you dont need the addContact function you jsut need to put it in a new array
  // and it doesnt make sense in this context so jsut do it here
  // then used json_decode and json_decode to read/save your json in
  // saveContact()
  $data = array(
    'fullname' => $_POST['fullname'],
    'email' => $_POST['email'],

  );

  // always return true if you save the contact data ok or false if it fails
  $response['status'] = saveContact($data) ? 'success' : 'error';
  $response['message'] = $response['status']

      : 'There was a problem saving your submission.';

  header('Content-type: application/json');
  echo json_encode($response);

            <input id="add_contact_submit" type="submit" name="submit" class="button" value="Add Contact" onClick="" />
            <input type="button" name="cancel" class="button" value="Reset" />
        </fieldset>
    </form>
    <script type="text/javascript">
     $(function(){
         $('#add_contact_submit').click(function(e){
            e.preventDefault();  
            $form = $(this).closest('form');

            // if you need to then wrap this ajax call in conditional logic

            $.ajax({
              url: $form.attr('action'),
              type: $form.attr('method'),
              dataType: 'json',
              success: function(responseJson) {
                 $form.before("<p>"+responseJson.message+"</p>");
              },
              error: function() {
                 $form.before("<p>There was an error processing your request.</p>");
              }
            });
         });         
     });
    </script>

• If your application wants to run in with port 80, and you can expose a different port to bind locally, say 8080:

  $ docker run -d --restart=always -p 8080:80 image_name:version
  

If you round 8.8333333333339 to 2 decimals, the correct answer is 8.83, not 8.84. The reason you got 8.83000000001 is because 8.83 is a number that cannot be correctly reprecented in binary, and it gives you the closest one. If you want to print it without all the zeros, do as VGE says:

print "%.2f" % 8.833333333339   #(Replace number with the variable?)

There are many way to do the string aggregation, but the easiest is a user defined function. Try this for a way that does not require a function. As a note, there is no simple way without the function.

This is the shortest route without a custom function: (it uses the ROW_NUMBER() and SYS_CONNECT_BY_PATH functions )

The following snippet will start an operation in a separate thread, then wait for up to 10 seconds for the operation to complete. If the operation does not complete in time, the code will attempt to cancel the operation, then continue on its merry way. Even if the operation cannot be cancelled easily, the parent thread will not wait for the child thread to terminate.

ExecutorService executorService = getExecutorService();
Future<SomeClass> future = executorService.submit(new Callable<SomeClass>() {
    public SomeClass call() {
        // Perform long-running task, return result. The code should check
        // interrupt status regularly, to facilitate cancellation.
    }
});
try {
    // Real life code should define the timeout as a constant or
    // retrieve it from configuration
    SomeClass result = future.get(10, TimeUnit.SECONDS);
    // Do something with the result
} catch (TimeoutException e) {
    future.cancel(true);
    // Perform other error handling, e.g. logging, throwing an exception
}

The getExecutorService() method can be implemented in a number of ways. If you do not have any particular requirements, you can simply call Executors.newCachedThreadPool() for thread pooling with no upper limit on the number of threads.

And don't forget to update gradle to 4.1+ (in gradle-wrapper.properties):

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

source: https://developer.android.com/studio/build/dependencies.html#google-maven

<?php $data = "<div><p>Welcome to my PHP class, we are glad you are here</p></div>"; echo strip_tags($data); ?>

Or if you have a content coming from the database;

<?php $data = strip_tags($get_row['description']); ?> <?=substr($data, 0, 100) ?><?php if(strlen($data) > 100) { ?>...<?php } ?>

It is used to escape special characters and print them as is. E.g. to print a double quote which is used to enclose strings, you need to escape it using the backslash character.

e.g.

System.out.println("printing \"this\" in quotes");

outputs

printing "this" in quotes

You need to go into the developer console and set

http://localhost:8080/WEBAPP/youtube-callback.html

as your callback URL.

This video is slightly outdated, as it shows the older Developer Console instead of the new one, however, the concepts should still apply. You need to find your project in the developer console and register a callback URL.

I ran into the same issue with Selenium and Behat. If you want to pass the parameters via behat.yml, here is what it needs to look like:

            base_url: https://my-app.com
            default_session: selenium2
            selenium2:

                capabilities:
                    extra_capabilities:
                        acceptInsecureCerts: true

Behold:

a = [4, 6, 12]
reduce(lambda c, x: c + [c[-1] + x], a, [0])[1:]

Will output (as expected):

[4, 10, 22]

try to change your method if you need to loop!

within the parent stored procedure, create a #temp table that contains the data that you need to process. Call the child stored procedure, the #temp table will be visible and you can process it, hopefully working with the entire set of data and without a cursor or loop.

this really depends on what this child stored procedure is doing. If you are UPDATE-ing, you can "update from" joining in the #temp table and do all the work in one statement without a loop. The same can be done for INSERT and DELETEs. If you need to do multiple updates with IFs you can convert those to multiple UPDATE FROM with the #temp table and use CASE statements or WHERE conditions.

When working in a database try to lose the mindset of looping, it is a real performance drain, will cause locking/blocking and slow down the processing. If you loop everywhere, your system will not scale very well, and will be very hard to speed up when users start complaining about slow refreshes.

Post the content of this procedure you want call in a loop, and I'll bet 9 out of 10 times, you could write it to work on a set of rows.

To answer your question in one sentence:

Per default, Maps don't have a last entry, it's not part of their contract.

And a side note: it's good practice to code against interfaces, not the implementation classes (see Effective Java by Joshua Bloch, Chapter 8, Item 52: Refer to objects by their interfaces).

So your declaration should read:

Map<String,Integer> map = new HashMap<String,Integer>();

(All maps share a common contract, so the client need not know what kind of map it is, unless he specifies a sub interface with an extended contract).

Possible Solutions

Sorted Maps:

There is a sub interface SortedMap that extends the map interface with order-based lookup methods and it has a sub interface NavigableMap that extends it even further. The standard implementation of this interface, TreeMap, allows you to sort entries either by natural ordering (if they implement the Comparable interface) or by a supplied Comparator.

You can access the last entry through the lastEntry method:

NavigableMap<String,Integer> map = new TreeMap<String, Integer>();
// add some entries
Entry<String, Integer> lastEntry = map.lastEntry();

Linked maps:

There is also the special case of LinkedHashMap, a HashMap implementation that stores the order in which keys are inserted. There is however no interface to back up this functionality, nor is there a direct way to access the last key. You can only do it through tricks such as using a List in between:

Map<String,String> map = new LinkedHashMap<String, Integer>();
// add some entries
List<Entry<String,Integer>> entryList =
    new ArrayList<Map.Entry<String, Integer>>(map.entrySet());
Entry<String, Integer> lastEntry =
    entryList.get(entryList.size()-1);

Proper Solution:

Since you don't control the insertion order, you should go with the NavigableMap interface, i.e. you would write a comparator that positions the Not-Specified entry last.

Here is an example:

final NavigableMap<String,Integer> map = 
        new TreeMap<String, Integer>(new Comparator<String>() {
    public int compare(final String o1, final String o2) {
        int result;
        if("Not-Specified".equals(o1)) {
            result=1;
        } else if("Not-Specified".equals(o2)) {
            result=-1;
        } else {
            result =o1.compareTo(o2);
        }
        return result;
    }

});
map.put("test", Integer.valueOf(2));
map.put("Not-Specified", Integer.valueOf(1));
map.put("testtest", Integer.valueOf(3));
final Entry<String, Integer> lastEntry = map.lastEntry();
System.out.println("Last key: "+lastEntry.getKey()
         + ", last value: "+lastEntry.getValue());

Output:

Last key: Not-Specified, last value: 1

Solution using HashMap:

If you must rely on HashMaps, there is still a solution, using a) a modified version of the above comparator, b) a List initialized with the Map's entrySet and c) the Collections.sort() helper method:

    final Map<String, Integer> map = new HashMap<String, Integer>();
    map.put("test", Integer.valueOf(2));
    map.put("Not-Specified", Integer.valueOf(1));
    map.put("testtest", Integer.valueOf(3));

    final List<Entry<String, Integer>> entries =
        new ArrayList<Entry<String, Integer>>(map.entrySet());
    Collections.sort(entries, new Comparator<Entry<String, Integer>>(){

        public int compareKeys(final String o1, final String o2){
            int result;
            if("Not-Specified".equals(o1)){
                result = 1;
            } else if("Not-Specified".equals(o2)){
                result = -1;
            } else{
                result = o1.compareTo(o2);
            }
            return result;
        }

        @Override
        public int compare(final Entry<String, Integer> o1,
            final Entry<String, Integer> o2){
            return this.compareKeys(o1.getKey(), o2.getKey());
        }

    });

    final Entry<String, Integer> lastEntry =
        entries.get(entries.size() - 1);
    System.out.println("Last key: " + lastEntry.getKey() + ", last value: "
        + lastEntry.getValue());

}

Output:

Last key: Not-Specified, last value: 1

While all the earlier responses address the issue they did not cover all cases.

Microsoft has acknowledged the issue and fixed it in 2011 for supported operating systems, so if you get the stack trace like:

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()
at System.Data.SqlClient.TdsParserStateObject.ReadSniError(TdsParserStateObject stateObj, UInt32 error)
at System.Data.SqlClient.TdsParserStateObject.ReadSni(DbAsyncResult asyncResult, TdsParserStateObject stateObj)

you may need to update your .NET assemblies.

This issue occurs because of an error in the connection-retry algorithm for mirrored databases.

When the retry-algorithm is used, the data provider waits for the first read (SniReadSync) call to finish. The call is sent to the back-end computer that is running SQL Server, and the waiting time is calculated by multiplying the connection time-out value by 0.08. However, the data provider incorrectly sets a connection to a doomed state if a response is slow and if the first SniReadSync call is not completed before the waiting time expires.

To see the dynamic SQL generated, change to text mode (_shortcut: Ctrl-T), then use SELECT

PRINT LEN(@Query) -- Prints out 4273, which is correct as far as I can tell
--SET NOCOUNT ON
SELECT @Query

As for sp_executesql, try this (in text mode), it should show the three aaaaa...'s the middle one being the longest with 'SELECT ..' added. Watch the Ln... Col.. indicator in the status bar at bottom right showing 4510 at the end of the 2nd output.

Just another approach if you are fine using temp tables.I have personally tested this and it will not cause any exception (even if temp table does not have any data.)

CREATE TABLE #TempTable
(
    ROWID int identity(1,1) primary key,
    HIERARCHY_ID_TO_UPDATE int,
)

--create some testing data
--INSERT INTO #TempTable VALUES(1)
--INSERT INTO #TempTable VALUES(2)
--INSERT INTO #TempTable VALUES(4)
--INSERT INTO #TempTable VALUES(6)
--INSERT INTO #TempTable VALUES(8)

DECLARE @MAXID INT, @Counter INT

SET @COUNTER = 1
SELECT @MAXID = COUNT(*) FROM #TempTable

WHILE (@COUNTER <= @MAXID)
BEGIN
    --DO THE PROCESSING HERE 
    SELECT @HIERARCHY_ID_TO_UPDATE = PT.HIERARCHY_ID_TO_UPDATE
    FROM #TempTable AS PT
    WHERE ROWID = @COUNTER

    SET @COUNTER = @COUNTER + 1
END


IF (OBJECT_ID('tempdb..#TempTable') IS NOT NULL)
BEGIN
    DROP TABLE #TempTable
END

You can't quite yet from what I read in the FAQ:

Do Go programs link with C/C++ programs?

There are two Go compiler implementations, gc (the 6g program and friends) and gccgo. Gc uses a different calling convention and linker and can therefore only be linked with C programs using the same convention. There is such a C compiler but no C++ compiler. Gccgo is a GCC front-end that can, with care, be linked with GCC-compiled C or C++ programs.

The cgo program provides the mechanism for a “foreign function interface” to allow safe calling of C libraries from Go code. SWIG extends this capability to C++ libraries.

Give the div a class or id and do something like this:

$("#example").get().innerHTML;

That works at the DOM level.

There's a new feature in 0.14.1, select_dtypes to select columns by dtype, by providing a list of dtypes to include or exclude.

For example:

df = pd.DataFrame({'a': np.random.randn(1000),
                   'b': range(1000),
                   'c': ['a'] * 1000,
                   'd': pd.date_range('2000-1-1', periods=1000)})


df.select_dtypes(['float64','int64'])

Mike, you might be interested in color filters.

An example:

try this to achieve the color you want.

If you want the Oracle JDK and are willing not to use yum/rpm, see this answer here:

Downloading Java JDK on Linux via wget is shown license page instead

As per that post, you can automate the download of the tarball using curl and specifying a cookie header.

Then you can put the tarball contents in the right place and add java to your PATH, for example:

curl -v -j -k -L -H "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u45-b14/jdk-8u45-linux-x64.tar.gz > jdk.tar.gz

tar xzvf jdk.tar.gz
sudo mkdir /usr/local/java
sudo mv jdk1.8.0_45 /usr/local/java/
sudo ln -s /usr/local/java/jdk1.8.0_45 /usr/local/java/jdk

sudo vi /etc/profile.d/java.sh
export PATH="$PATH:/usr/local/java/jdk/bin"
export JAVA_HOME=/usr/local/java/jdk

source /etc/profile.d/java.sh

Note, not only there is dependency on .panel, it also has dependency on the DOM structure.

Make sure your elements are structured like this:

    <div id="parent-id">
        <div class="panel">
            <a data-toggle="collapse" data-target="#opt1" data-parent="#parent-id">Control</a>
            <div id="opt1" class="collapse">
...

It's basically what @Blazemonger said, but I think the hierarchy of the target element matters too. I didn't finish trying every possibility out, but basically it should work if you follow this hierarchy.

FYI, I had more layers between the control div & content div and that didn't work.

If you are using ASP.NET then you can use

yourControlName.Focus()

in the code on the server, which will add appropriate JavaScript into the page.

Other server-side frameworks may have an equivalent method.

This can be done with a HTTP Post request to the server:

HttpClient http = AndroidHttpClient.newInstance("MyApp");
HttpPost method = new HttpPost("http://url-to-server");

method.setEntity(new FileEntity(new File("path-to-file"), "application/octet-stream"));

HttpResponse response = http.execute(method);

It should be a problem in your version of grep.

Your test cases are working correctly here on my machine:

$ echo "ABC" | grep -io abc
ABC

And my version is:

To prevent full size category images slowing page down, you can use smaller images with wp_get_attachment_image_src():

<?php 

$thumbnail_id = get_woocommerce_term_meta( $term->term_id, 'thumbnail_id', true );

// get the medium-sized image url
$image = wp_get_attachment_image_src( $thumbnail_id, 'medium' );

// Output in img tag
echo '<img src="' . $image[0] . '" alt="" />'; 

// Or as a background for a div
echo '<div class="image" style="background-image: url("' . $image[0] .'")"></div>';

?>

I believe that the password expiration behavior, by default, is to never expire. However, you could set up a profile for your dev user set and set the PASSWORD_LIFE_TIME. See the orafaq for more details. You can see here for an example of one person's perspective and usage.

Saw this thread while looking for something else and I know it is super old, but I wanted to add my 2 cents.

NEVER USE VLOOKUP. It's one of the worst performing formulas in excel. Use index match instead. It even works without sorting data, unless you have a -1 or 1 in the end of the match formula (explained more below)

Here is a link with the appropriate formulas.

The Sheet 2 formula would be this: =IF(A2="","",INDEX(Sheet1!B:B,MATCH($A2,Sheet1!$A:$A,0)))

• IF(A2="","", means if A2 is blank, return a blank value
• INDEX(Sheet1!B:B, is saying INDEX B:B where B:B is the data you want to return. IE the name column.
• Match(A2, is saying to Match A2 which is the ID you want to return the Name for.
• Sheet1!A:A, is saying you want to match A2 to the ID column in the previous sheet
• ,0)) is specifying you want an exact value. 0 means return an exact match to A2, -1 means return smallest value greater than or equal to A2, 1 means return the largest value that is less than or equal to A2. Keep in mind -1 and 1 have to be sorted.

More information on the Index/Match formula

Other fun facts: $ means absolute in a formula. So if you specify $B$1 when filling a formula down or over keeps that same value. If you over $B1, the B remains the same across the formula, but if you fill down, the 1 increases with the row count. Likewise, if you used B$1, filling to the right will increment the B, but keep the reference of row 1.

I also included the use of indirect in the second section. What indirect does is allow you to use the text of another cell in a formula. Since I created a named range sheet1!A:A = ID, sheet1!B:B = Name, and sheet1!C:C=Price, I can use the column name to have the exact same formula, but it uses the column heading to change the search criteria.

Good luck! Hope this helps.

You can directly convert to an int using the str::parse::<T>() method.

let my_string = "27".to_string();  // `parse()` works with `&str` and `String`!
let my_int = my_string.parse::<i32>().unwrap();

You can either specify the type to parse to with the turbofish operator (::<>) as shown above or via explicit type annotation:

let my_int: i32 = my_string.parse().unwrap();

As mentioned in the comments, parse() returns a Result. This result will be an Err if the string couldn't be parsed as the type specified (for example, the string "peter" can't be parsed as i32).

I faced the same issue:

E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation

I resolved by using the following commands:

apt-get update
apt-get install gnupg

I am fairly sure that Linq can do this.... but MyList does not have a select method on it (which is what I would have used).

Yes, LINQ can do this. It's simply:

MyList.Select(x => x.Name).ToArray();

Most likely the issue is that you either don't have a reference to System.Core, or you are missing an using directive for System.Linq.

Here in my sample I find out the solution of this, because I had the same problem with updates and subquerys:

UPDATE
    A
SET
    A.ValueToChange = B.NewValue
FROM
    (
        Select * From C
    ) B
Where 
    A.Id = B.Id

I faced the same problem due to illegal spaces in my entire code.

I fixed it by selecting one of these spaces and use find and replace to replace all matches with regular spaces.

You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.

Example:

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      window.location.href = 'https://website.com/my-account';
    }
  };
  xhttp.open("POST", "demo_post.asp", true);
  xhttp.send();

set -x is fine.

Another way to print each executed command is to use trap with DEBUG. Put this line at the beginning of your script :

trap 'echo "# $BASH_COMMAND"' DEBUG

You can find a lot of other trap usages here.

If you can't add to the BODY tag for some reason, you can add this AFTER the Form:

<SCRIPT type="text/javascript">
    document.yourFormName.yourFieldName.focus();
</SCRIPT>

If you just want to get the information of current directory, you can type:

pwd

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.

You can use TelephonyManager to do that .

var json = jQuery.parseJSON(s); //If you have jQuery.

Since the comment looks cluttered, please use the parse function after enclosing those square brackets inside the quotes.

var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];

Change the above code to

var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

Eg:

$(document).ready(function() {
    var s= '[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

    s = jQuery.parseJSON(s);

    alert( s[0]["Select"] );
});

And then use the parse function. It'll surely work.

EDIT :Extremely sorry that I gave the wrong function name. it's jQuery.parseJSON

Jquery

The json api

Edit (30 April 2020):

Editing since I got an upvote for this answer. There's a browser native function available instead of JQuery (for nonJQuery users), JSON.parse("<json string here>")

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

For single string find in power shell

./adb shell getprop | Select-String -Pattern 'model'

or

./adb shell getprop | Select-String -Pattern '(model)'

For multiple

./adb shell getprop | Select-String -Pattern '(a|b|c|d)'

simple example:

<div ng-style="isTrue && {'background-color':'green'} || {'background-color': 'blue'}" style="width:200px;height:100px;border:1px solid gray;"></div>

{'background-color':'green'} RETURN true

OR the same result:

<div ng-style="isTrue && {'background-color':'green'}" style="width:200px;height:100px;border:1px solid gray;background-color: blue"></div>

other conditional possibility:

<div ng-style="count === 0 && {'background-color':'green'}  || count === 1 && {'background-color':'yellow'}" style="width:200px;height:100px;border:1px solid gray;background-color: blue"></div>

After installing weblogic and forms server on a Linux machine we met some problems initializing sqlplus and tnsping. We altered the bash_profile in a way that the forms_home acts as the oracle home. It works fine, both commands (sqlplus and tnsping) are executable for user oracle

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

export FORMS_PATH=$FORMS_PATH:/oracle/Middleware/Oracle_FRHome1/forms:/oracle/Middleware/asinst_1/FormsComponent/forms:/appl/myapp:/home/oracle/myapp

You can achieve with following way

    this.projectService.create(project)
    .subscribe(
        result => {
         console.log(result);
        },
        error => {
            console.log(error);
            this.errors = error
        }
    ); 
}

if (!this.errors) {
    //route to new page
}

How about

sub foo()
  dim r As Range, rows As Long, i As Long
  Set r = ActiveSheet.Range("A1:Z50")
  rows = r.rows.Count
  For i = rows To 1 Step (-1)
    If WorksheetFunction.CountA(r.rows(i)) = 0 Then r.rows(i).Delete
  Next
End Sub

Try this

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50
        If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
            If DelRange Is Nothing Then
                Set DelRange = Range("A" & i & ":" & "Z" & i)
            Else
                Set DelRange = Union(DelRange, Range("A" & i & ":" & "Z" & i))
            End If
        End If
    Next i

    If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
    Application.ScreenUpdating = True

    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume LetsContinue
End Sub

IF you want to delete the entire row then use this code

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50

Background: What’s an Optional?

In Swift, Optional<Wrapped> is an option type: it can contain any value from the original ("Wrapped") type, or no value at all (the special value nil). An optional value must be unwrapped before it can be used.

Optional is a generic type, which means that Optional<Int> and Optional<String> are distinct types — the type inside <> is called the Wrapped type. Under the hood, an Optional is an enum with two cases: .some(Wrapped) and .none, where .none is equivalent to nil.

Optionals can be declared using the named type Optional<T>, or (most commonly) as a shorthand with a ? suffix.

var anInt: Int = 42
var anOptionalInt: Int? = 42
var anotherOptionalInt: Int?  // `nil` is the default when no value is provided
var aVerboseOptionalInt: Optional<Int>  // equivalent to `Int?`

anOptionalInt = nil // now this variable contains nil instead of an integer

Optionals are a simple yet powerful tool to express your assumptions while writing code. The compiler can use this information to prevent you from making mistakes. From The Swift Programming Language:

Swift is a type-safe language, which means the language helps you to be clear about the types of values your code can work with. If part of your code requires a String, type safety prevents you from passing it an Int by mistake. Likewise, type safety prevents you from accidentally passing an optional String to a piece of code that requires a non-optional String. Type safety helps you catch and fix errors as early as possible in the development process.

Some other programming languages also have generic option types: for example, Maybe in Haskell, option in Rust, and optional in C++17.

In programming languages without option types, a particular "sentinel" value is often used to indicate the absence of a valid value. In Objective-C, for example, nil (the null pointer) represents the lack of an object. For primitive types such as int, a null pointer can't be used, so you would need either a separate variable (such as value: Int and isValid: Bool) or a designated sentinel value (such as -1 or INT_MIN). These approaches are error-prone because it's easy to forget to check isValid or to check for the sentinel value. Also, if a particular value is chosen as the sentinel, that means it can no longer be treated as a valid value.

Option types such as Swift's Optional solve these problems by introducing a special, separate nil value (so you don't have to designate a sentinel value), and by leveraging the strong type system so the compiler can help you remember to check for nil when necessary.

Why did I get “fatal error: unexpectedly found nil while unwrapping an Optional value”?

In order to access an optional’s value (if it has one at all), you need to unwrap it. An optional value can be unwrapped safely or forcibly. If you force-unwrap an optional, and it didn't have a value, your program will crash with the above message.

Xcode will show you the crash by highlighting a line of code. The problem occurs on this line.

This crash can occur with two different kinds of force-unwrap:

1. Explicit Force Unwrapping

This is done with the ! operator on an optional. For example:

let anOptionalString: String?
print(anOptionalString!) // <- CRASH

Fatal error: Unexpectedly found nil while unwrapping an Optional value

As anOptionalString is nil here, you will get a crash on the line where you force unwrap it.

2. Implicitly Unwrapped Optionals

These are defined with a !, rather than a ? after the type.

var optionalDouble: Double!   // this value is implicitly unwrapped wherever it's used

These optionals are assumed to contain a value. Therefore whenever you access an implicitly unwrapped optional, it will automatically be force unwrapped for you. If it doesn’t contain a value, it will crash.

print(optionalDouble) // <- CRASH

Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

In order to work out which variable caused the crash, you can hold ? while clicking to show the definition, where you might find the optional type.

IBOutlets, in particular, are usually implicitly unwrapped optionals. This is because your xib or storyboard will link up the outlets at runtime, after initialization. You should therefore ensure that you’re not accessing outlets before they're loaded in. You also should check that the connections are correct in your storyboard/xib file, otherwise the values will be nil at runtime, and therefore crash when they are implicitly unwrapped. When fixing connections, try deleting the lines of code that define your outlets, then reconnect them.

When should I ever force unwrap an Optional?

Explicit Force Unwrapping

As a general rule, you should never explicitly force unwrap an optional with the ! operator. There may be cases where using ! is acceptable – but you should only ever be using it if you are 100% sure that the optional contains a value.

While there may be an occasion where you can use force unwrapping, as you know for a fact that an optional contains a value – there is not a single place where you cannot safely unwrap that optional instead.

Implicitly Unwrapped Optionals

These variables are designed so that you can defer their assignment until later in your code. It is your responsibility to ensure they have a value before you access them. However, because they involve force unwrapping, they are still inherently unsafe – as they assume your value is non-nil, even though assigning nil is valid.

You should only be using implicitly unwrapped optionals as a last resort. If you can use a lazy variable, or provide a default value for a variable – you should do so instead of using an implicitly unwrapped optional.

However, there are a few scenarios where implicitly unwrapped optionals are beneficial, and you are still able to use various ways of safely unwrapping them as listed below – but you should always use them with due caution.

How can I safely deal with Optionals?

The simplest way to check whether an optional contains a value, is to compare it to nil.

if anOptionalInt != nil {
    print("Contains a value!")
} else {
    print("Doesn’t contain a value.")
}

However, 99.9% of the time when working with optionals, you’ll actually want to access the value it contains, if it contains one at all. To do this, you can use Optional Binding.

Optional Binding

Optional Binding allows you to check if an optional contains a value – and allows you to assign the unwrapped value to a new variable or constant. It uses the syntax if let x = anOptional {...} or if var x = anOptional {...}, depending if you need to modify the value of the new variable after binding it.

For example:

if let number = anOptionalInt {
    print("Contains a value! It is \(number)!")
} else {
    print("Doesn’t contain a number")
}

What this does is first check that the optional contains a value. If it does, then the ‘unwrapped’ value is assigned to a new variable (number) – which you can then freely use as if it were non-optional. If the optional doesn’t contain a value, then the else clause will be invoked, as you would expect.

What’s neat about optional binding, is you can unwrap multiple optionals at the same time. You can just separate the statements with a comma. The statement will succeed if all the optionals were unwrapped.

var anOptionalInt : Int?
var anOptionalString : String?

if let number = anOptionalInt, let text = anOptionalString {
    print("anOptionalInt contains a value: \(number). And so does anOptionalString, it’s: \(text)")
} else {
    print("One or more of the optionals don’t contain a value")
}

Another neat trick is that you can also use commas to check for a certain condition on the value, after unwrapping it.

if let number = anOptionalInt, number > 0 {
    print("anOptionalInt contains a value: \(number), and it’s greater than zero!")
}

The only catch with using optional binding within an if statement, is that you can only access the unwrapped value from within the scope of the statement. If you need access to the value from outside of the scope of the statement, you can use a guard statement.

A guard statement allows you to define a condition for success – and the current scope will only continue executing if that condition is met. They are defined with the syntax guard condition else {...}.

So, to use them with an optional binding, you can do this:

guard let number = anOptionalInt else {
    return
}

^{(Note that within the guard body, you must use one of the control transfer statements in order to exit the scope of the currently executing code).}

If anOptionalInt contains a value, it will be unwrapped and assigned to the new number constant. The code after the guard will then continue executing. If it doesn’t contain a value – the guard will execute the code within the brackets, which will lead to transfer of control, so that the code immediately after will not be executed.

The real neat thing about guard statements is the unwrapped value is now available to use in code that follows the statement (as we know that future code can only execute if the optional has a value). This is a great for eliminating ‘pyramids of doom’ created by nesting multiple if statements.

For example:

guard let number = anOptionalInt else {
    return
}

print("anOptionalInt contains a value, and it’s: \(number)!")

Guards also support the same neat tricks that the if statement supported, such as unwrapping multiple optionals at the same time and using the where clause.

Whether you use an if or guard statement completely depends on whether any future code requires the optional to contain a value.

Nil Coalescing Operator

The Nil Coalescing Operator is a nifty shorthand version of the ternary conditional operator, primarily designed to convert optionals to non-optionals. It has the syntax a ?? b, where a is an optional type and b is the same type as a (although usually non-optional).

It essentially lets you say “If a contains a value, unwrap it. If it doesn’t then return b instead”. For example, you could use it like this:

let number = anOptionalInt ?? 0

This will define a number constant of Int type, that will either contain the value of anOptionalInt, if it contains a value, or 0 otherwise.

It’s just shorthand for:

let number = anOptionalInt != nil ? anOptionalInt! : 0

Optional Chaining

You can use Optional Chaining in order to call a method or access a property on an optional. This is simply done by suffixing the variable name with a ? when using it.

For example, say we have a variable foo, of type an optional Foo instance.

var foo : Foo?

If we wanted to call a method on foo that doesn’t return anything, we can simply do:

foo?.doSomethingInteresting()

If foo contains a value, this method will be called on it. If it doesn’t, nothing bad will happen – the code will simply continue executing.

^{(This is similar behaviour to sending messages to nil in Objective-C)}

This can therefore also be used to set properties as well as call methods. For example:

foo?.bar = Bar()

Again, nothing bad will happen here if foo is nil. Your code will simply continue executing.

Another neat trick that optional chaining lets you do is check whether setting a property or calling a method was successful. You can do this by comparing the return value to nil.

^{(This is because an optional value will return Void? rather than Void on a method that doesn’t return anything)}

For example:

if (foo?.bar = Bar()) != nil {
    print("bar was set successfully")
} else {
    print("bar wasn’t set successfully")
}

However, things become a little bit more tricky when trying to access properties or call methods that return a value. Because foo is optional, anything returned from it will also be optional. To deal with this, you can either unwrap the optionals that get returned using one of the above methods – or unwrap foo itself before accessing methods or calling methods that return values.

Also, as the name suggests, you can ‘chain’ these statements together. This means that if foo has an optional property baz, which has a property qux – you could write the following:

let optionalQux = foo?.baz?.qux

Again, because foo and baz are optional, the value returned from qux will always be an optional regardless of whether qux itself is optional.

map and flatMap

An often underused feature with optionals is the ability to use the map and flatMap functions. These allow you to apply non-optional transforms to optional variables. If an optional has a value, you can apply a given transformation to it. If it doesn’t have a value, it will remain nil.

For example, let’s say you have an optional string:

let anOptionalString:String?

By applying the map function to it – we can use the stringByAppendingString function in order to concatenate it to another string.

Because stringByAppendingString takes a non-optional string argument, we cannot input our optional string directly. However, by using map, we can use allow stringByAppendingString to be used if anOptionalString has a value.

For example:

var anOptionalString:String? = "bar"

anOptionalString = anOptionalString.map {unwrappedString in
    return "foo".stringByAppendingString(unwrappedString)
}

print(anOptionalString) // Optional("foobar")

However, if anOptionalString doesn’t have a value, map will return nil. For example:

var anOptionalString:String?

anOptionalString = anOptionalString.map {unwrappedString in
    return "foo".stringByAppendingString(unwrappedString)
}

print(anOptionalString) // nil

flatMap works similarly to map, except it allows you to return another optional from within the closure body. This means you can input an optional into a process that requires a non-optional input, but can output an optional itself.

try!

Swift's error handling system can be safely used with Do-Try-Catch:

do {
    let result = try someThrowingFunc() 
} catch {
    print(error)
}

If someThrowingFunc() throws an error, the error will be safely caught in the catch block.

The error constant you see in the catch block has not been declared by us - it's automatically generated by catch.

You can also declare error yourself, it has the advantage of being able to cast it to a useful format, for example:

do {
    let result = try someThrowingFunc()    
} catch let error as NSError {
    print(error.debugDescription)
}

Using try this way is the proper way to try, catch and handle errors coming from throwing functions.

There's also try? which absorbs the error:

if let result = try? someThrowingFunc() {
    // cool
} else {
    // handle the failure, but there's no error information available
}

But Swift's error handling system also provides a way to "force try" with try!:

let result = try! someThrowingFunc()

The concepts explained in this post also apply here: if an error is thrown, the application will crash.

You should only ever use try! if you can prove that its result will never fail in your context - and this is very rare.

Most of the time you will use the complete Do-Try-Catch system - and the optional one, try?, in the rare cases where handling the error is not important.

list2 = ['%sbar' % (x,) for x in list]

And don't use list as a name; it shadows the built-in type.

The simplest (but not the fastest) way to iterate a directory tree and list relative file paths is to use FORFILES.

forfiles /s /m *.txt /c "cmd /c echo @relpath"

The relative paths will be quoted with a leading .\ as in

".\Doc1.txt"
".\subdir\Doc2.txt"
".\subdir\Doc3.txt"

To remove quotes:

for /f %%A in ('forfiles /s /m *.txt /c "cmd /c echo @relpath"') do echo %%~A

To remove quotes and the leading .\:

setlocal disableDelayedExpansion
for /f "delims=" %%A in ('forfiles /s /m *.txt /c "cmd /c echo @relpath"') do (
  set "file=%%~A"
  setlocal enableDelayedExpansion
  echo !file:~2!
  endlocal
)

or without using delayed expansion

for /f "tokens=1* delims=\" %%A in (
  'forfiles /s /m *.txt /c "cmd /c echo @relpath"'
) do for %%F in (^"%%B) do echo %%~F

Something less verbose, std and takes anything separated by a comma.

stringstream ss( "1,1,1,1, or something else ,1,1,1,0" );
vector<string> result;

while( ss.good() )
{
    string substr;
    getline( ss, substr, ',' );
    result.push_back( substr );
}

The accepted answer uses the Apache Commons package but this is how I did it using Java's native libraries

Java 11 and up

import java.util.Base64;

public class Base64Encoding {

    public static void main(String[] args) {
        Base64.Encoder enc = Base64.getEncoder();
        Base64.Decoder dec = Base64.getDecoder();
        String str = "77+9x6s=";

        // encode data using BASE64
        String encoded = enc.encodeToString(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data
        String decoded = new String(dec.decode(encoded));
        System.out.println("decoded value is \t" + decoded);
        System.out.println("original value is \t" + str);
    }
}

Java 6 - 10

import java.io.UnsupportedEncodingException;    
import javax.xml.bind.DatatypeConverter;

public class EncodeString64 {
    public static void main(String[] args) throws UnsupportedEncodingException {

        String str = "77+9x6s=";
        // encode data using BASE64
        String encoded = DatatypeConverter.printBase64Binary(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data 
        String decoded = new String(DatatypeConverter.parseBase64Binary(encoded));
        System.out.println("decoded value is \t" + decoded);

        System.out.println("original value is \t" + str);
    }
}

The better way would be to try/catch the encoding/decoding steps but hopefully you get the idea.

Since strings in Python are immutable, you cannot "make it" anything different. You can however, create a new raw string from s, like this:

raw_s = r'{}'.format(s)

Simulator doesn't have a Camera. If you want to access a camera you need a device. You can't test camera on simulator. You can only check the photo and video gallery.

In my case I had to uninstall hyper-v, restart pc, and run docker again.

tl;dr:

There are 3 main issues with multithreading:

1) Race Conditions

2) Caching / stale memory

3) Complier and CPU optimisations

volatile can solve 2 & 3, but can't solve 1. synchronized/explicit locks can solve 1, 2 & 3.

Elaboration:

1) Consider this thread unsafe code:

x++;

While it may look like one operation, it's actually 3: reading the current value of x from memory, adding 1 to it, and saving it back to memory. If few threads try to do it at the same time, the result of the operation is undefined. If x originally was 1, after 2 threads operating the code it may be 2 and it may be 3, depending on which thread completed which part of the operation before control was transferred to the other thread. This is a form of race condition.

Using synchronized on a block of code makes it atomic - meaning it make it as if the 3 operations happen at once, and there's no way for another thread to come in the middle and interfere. So if x was 1, and 2 threads try to preform x++ we know in the end it will be equal to 3. So it solves the race condition problem.

synchronized (this) {
   x++; // no problem now
}

Marking x as volatile does not make x++; atomic, so it doesn't solve this problem.

2) In addition, threads have their own context - i.e. they can cache values from main memory. That means that a few threads can have copies of a variable, but they operate on their working copy without sharing the new state of the variable among other threads.

Consider that on one thread, x = 10;. And somewhat later, in another thread, x = 20;. The change in value of x might not appear in the first thread, because the other thread has saved the new value to its working memory, but hasn't copied it to the main memory. Or that it did copy it to the main memory, but the first thread hasn't updated its working copy. So if now the first thread checks if (x == 20) the answer will be false.

Marking a variable as volatile basically tells all threads to do read and write operations on main memory only. synchronized tells every thread to go update their value from main memory when they enter the block, and flush the result back to main memory when they exit the block.

Note that unlike data races, stale memory is not so easy to (re)produce, as flushes to main memory occur anyway.

3) The complier and CPU can (without any form of synchronization between threads) treat all code as single threaded. Meaning it can look at some code, that is very meaningful in a multithreading aspect, and treat it as if it’s single threaded, where it’s not so meaningful. So it can look at a code and decide, in sake of optimisation, to reorder it, or even remove parts of it completely, if it doesn’t know that this code is designed to work on multiple threads.

Consider the following code:

boolean b = false;
int x = 10;

void threadA() {
    x = 20;
    b = true;
}

void threadB() {
    if (b) {
        System.out.println(x);
    }
}

You would think that threadB could only print 20 (or not print anything at all if threadB if-check is executed before setting b to true), as b is set to true only after x is set to 20, but the compiler/CPU might decide to reorder threadA, in that case threadB could also print 10. Marking b as volatile ensures that it won’t be reordered (or discarded in certain cases). Which mean threadB could only print 20 (or nothing at all). Marking the methods as syncrhonized will achieve the same result. Also marking a variable as volatile only ensures that it won’t get reordered, but everything before/after it can still be reordered, so synchronization can be more suited in some scenarios.

Note that before Java 5 New Memory Model, volatile didn’t solve this issue.

Reading the friendly manual? Who'd want to do that?

If you are on Visual Studio 2017 you need at least CMake 3.8!

The easiest approach I know of is using onresize() func:

   window.onresize = function(event) {
        ...
    }

Here is a fiddle for it

  newlist=[]                       #make an empty list
  for i in list:                   # loop to hv a dict in list  
     s={}                          # make an empty dict to store new dict data 
     for k in i.keys():            # to get keys in the dict of the list 
         s[k]=int(i[k])        # change the values from string to int by int func
     newlist.append(s)             # to add the new dict with integer to the list

pod deintegrate <PROJECT>.XCODEPROJ // will deintegrate cocoapods
pod install // installs the pods

mysql_ functions have been removed from PHP 7. You can now use MySQLi or PDO.

MySQLi example:

mysqli_connect($mysql_hostname, $mysql_username, $mysql_password, $mysql_dbname);

mysqli_connect reference link

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("/icon.png")));

If your icon.png is in resources dir and remember to put a '/' before otherwise it will not work

If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:

• GPU Usage Tool in Visual Studio (video) https://www.youtube.com/watch?v=Gjc5bPXGkTE
• GPU Usage Visual Studio 2015 https://msdn.microsoft.com/en-us/library/mt126195.aspx
• GPU Usage tool in Visual Studio 2013 Update 4 CTP1 (blog) http://blogs.msdn.com/b/vcblog/archive/2014/09/05/gpu-usage-tool-in-visual-studio-2013-update-4-ctp1.aspx
• GPU Usage for DirectX in Visual Studio (blog) http://blogs.msdn.com/b/ianhu/archive/2014/12/16/gpu-usage-for-directx-in-visual-studio.aspx

Screenshot from MSDN:

Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:

In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

I ran into this issue multiple times, and the solution which I found is to delete the debug folder and then rebuild your solution/project. Worked for me!!

df[df.columns[i]]

where i is the position/number of the column(starting from 0).

So, i = 0 is for the first column.

You can also get the last column using i = -1

import java.text.SimpleDateFormat;
import java.text.DateFormat;
import java.util.Date;

public class Main {
   public static void main(String [] args){
       try {
            DateFormat parseFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm a");
            String sDate = "22-01-2019 13:35 PM";
            Date date = parseFormat.parse(sDate);
            SimpleDateFormat displayFormat = new SimpleDateFormat("dd-MM-yyyy hh:mm a");
            sDate = displayFormat.format(date);
            System.out.println("The required format : " + sDate);
        } catch (Exception e) {}
   }
}

position: relative act as a parent element position: absolute act a child of relative position. you can see the below example

.postion-element{
   position:relative;
   width:200px;
   height:200px;
   background-color:green;
 }
.absolute-element{
  position:absolute;
  top:10px;
  left:10px;
  background-color:blue;
 }

I can provide two ways,

a.jsp,

<html>
    <script language="javascript" type="text/javascript">
        function call(){
            var name = "xyz";
            window.location.replace("a.jsp?name="+name);
        }
    </script>
    <input type="button" value="Get" onclick='call()'>
    <%
        String name=request.getParameter("name");
        if(name!=null){
            out.println(name);
        }
    %>
</html>

b.jsp,

<script>
    var v="xyz";
</script>
<% 
    String st="<script>document.writeln(v)</script>";
    out.println("value="+st); 
%>

In CI v3, you can try:

function partial_uri($start = 0) {
    return join('/',array_slice(get_instance()->uri->segment_array(), $start));
}

This will drop the number of URL segments specified by the $start argument. If your URL is http://localhost/dropbox/derrek/shopredux/ahahaha/hihihi, then:

partial_uri(3);  # returns "ahahaha/hihihi"

Try setting "Integrated Security=False" in the connection string.

<add name="YourContext" connectionString="Data Source=<IPAddressOfDBServer>;Initial Catalog=<DBName>;USER ID=<youruserid>;Password=<yourpassword>;Integrated Security=False;MultipleActiveResultSets=True" providerName="System.Data.SqlClient"/>

You can create constants in many different ways:

const myString = "hello"
const pi = 3.14 // untyped constant
const life int = 42 // typed constant (can use only with ints)

You can also create a enum constant:

const ( 
   First = 1
   Second = 2
   Third = 4
)

You can not create constants of maps, arrays and it is written in effective go:

Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers, characters (runes), strings or booleans. Because of the compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function call to math.Sin needs to happen at run time.

This may not be the prettiest, but if you don't want to use the MessageBoxManager, (which is awesome):

 public static DialogResult DialogBox(string title, string promptText, ref string value, string button1 = "OK", string button2 = "Cancel", string button3 = null)
    {
        Form form = new Form();
        Label label = new Label();
        TextBox textBox = new TextBox();
        Button button_1 = new Button();
        Button button_2 = new Button();
        Button button_3 = new Button();

        int buttonStartPos = 228; //Standard two button position


        if (button3 != null)
            buttonStartPos = 228 - 81;
        else
        {
            button_3.Visible = false;
            button_3.Enabled = false;
        }


        form.Text = title;

        // Label
        label.Text = promptText;
        label.SetBounds(9, 20, 372, 13);
        label.Font = new Font("Microsoft Tai Le", 10, FontStyle.Regular);

        // TextBox
        if (value == null)
        {
        }
        else
        {
            textBox.Text = value;
            textBox.SetBounds(12, 36, 372, 20);
            textBox.Anchor = textBox.Anchor | AnchorStyles.Right;
        }

        button_1.Text = button1;
        button_2.Text = button2;
        button_3.Text = button3 ?? string.Empty;
        button_1.DialogResult = DialogResult.OK;
        button_2.DialogResult = DialogResult.Cancel;
        button_3.DialogResult = DialogResult.Yes;


        button_1.SetBounds(buttonStartPos, 72, 75, 23);
        button_2.SetBounds(buttonStartPos + 81, 72, 75, 23);
        button_3.SetBounds(buttonStartPos + (2 * 81), 72, 75, 23);

        label.AutoSize = true;
        button_1.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;
        button_2.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;
        button_3.Anchor = AnchorStyles.Bottom | AnchorStyles.Right;

        form.ClientSize = new Size(396, 107);
        form.Controls.AddRange(new Control[] { label, button_1, button_2 });
        if (button3 != null)
            form.Controls.Add(button_3);
        if (value != null)
            form.Controls.Add(textBox);

        form.ClientSize = new Size(Math.Max(300, label.Right + 10), form.ClientSize.Height);
        form.FormBorderStyle = FormBorderStyle.FixedDialog;
        form.StartPosition = FormStartPosition.CenterScreen;
        form.MinimizeBox = false;
        form.MaximizeBox = false;
        form.AcceptButton = button_1;
        form.CancelButton = button_2;

        DialogResult dialogResult = form.ShowDialog();
        value = textBox.Text;
        return dialogResult;
    }

I had the same issue. When developing I wanted to bypass screens. I was navigating from one view controller to another in viewDidLoad by calling a selector method.

The issue is that we should let the ViewController finish transitioning before transitioning to another ViewController.

This solved my problem: The delay is necessary to allow ViewControllers finish transitioning before transitioning to another.

self.perform(#selector(YOUR SELECTOR METHOD), with: self, afterDelay: 0.5)

Solution for the code you posted:

.center{
    position:absolute;
    width:780px;
    height:650px;
    left:50%;
    top:50%;
    margin-left:-390px;
    margin-top:-325px;
}

<table class="center" width="780" border="0" align="center" cellspacing="2" bordercolor="#000000" bgcolor="#FFCC66">
      <tr>
        <td>
        <table width="100%" border="0">
      <tr>
        <td>
        <table width="100%" border="0">
        <tr>
            <td width="150"><img src="images/banners/BAX Company.jpg" width="149" height="130" /></td>
            <td width="150"><img src="images/banners/BAX Location.jpg" width="149" height="130" /></td>
            <td width="300"><img src="images/banners/Closet.jpg" width="300" height="130" /></td>
            <td width="150"><img src="images/banners/BAX Company.jpg" width="149" height="130" /></td>
            <td width="150"><img src="images/banners/BAX Location.jpg" width="149" height="130" /></td>        
        </tr>
        </table>
        </td>
      </tr>
      <tr>
        <td>
        <table width="100%" border="0">
        <tr>
            <td width="150"><img src="images/banners/BAX Company.jpg" width="149" height="130" /></td>
            <td width="150"><img src="images/banners/BAX Location.jpg" width="149" height="130" /></td>
            <td width="300"><img src="images/banners/Closet.jpg" width="300" height="130" /></td>
            <td width="150"><img src="images/banners/BAX Company.jpg" width="149" height="130" /></td>
            <td width="150"><img src="images/banners/BAX Location.jpg" width="149" height="130" /></td>        
        </tr>
        </table>
        </td>
      </tr>
</table>

How this works?

Example: http://jsfiddle.net/953Yj/

<div class="center">
    Lorem ipsum
</div>

.center{
    position:absolute;
    height: X px;
    width: Y px;
    left:50%;
    top:50%;
    margin-top:- X/2 px;
    margin-left:- Y/2 px;
}

• X would your your height.
• Y would be your width.

To position the div vertically and horizontally, divide X and Y by 2.

DateTime has a Subtract method and an overloaded - operator for just such an occasion:

DateTime now = DateTime.UtcNow;
TimeSpan difference = now.Subtract(otherTime); // could also write `now - otherTime`
if (difference.TotalSeconds > 5) { ... }

Instead of this:

CheckboxList1.Items[i].value;

Try This:

CheckboxList1.Items[i].ToString();

It worked for me :)

days, hours, minutes = td.days, td.seconds // 3600, td.seconds // 60 % 60

As for DST, I think the best thing is to convert both datetime objects to seconds. This way the system calculates DST for you.

>>> m13 = datetime(2010, 3, 13, 8, 0, 0)  # 2010 March 13 8:00 AM
>>> m14 = datetime(2010, 3, 14, 8, 0, 0)  # DST starts on this day, in my time zone
>>> mktime(m14.timetuple()) - mktime(m13.timetuple())     # difference in seconds
82800.0
>>> _/3600                                                # convert to hours
23.0

In the vast majority of cases, the "stringification" of a SQLAlchemy statement or query is as simple as:

print(str(statement))

This applies both to an ORM Query as well as any select() or other statement.

Note: the following detailed answer is being maintained on the sqlalchemy documentation.

To get the statement as compiled to a specific dialect or engine, if the statement itself is not already bound to one you can pass this in to compile():

print(statement.compile(someengine))

or without an engine:

from sqlalchemy.dialects import postgresql
print(statement.compile(dialect=postgresql.dialect()))

When given an ORM Query object, in order to get at the compile() method we only need access the .statement accessor first:

statement = query.statement
print(statement.compile(someengine))

with regards to the original stipulation that bound parameters are to be "inlined" into the final string, the challenge here is that SQLAlchemy normally is not tasked with this, as this is handled appropriately by the Python DBAPI, not to mention bypassing bound parameters is probably the most widely exploited security holes in modern web applications. SQLAlchemy has limited ability to do this stringification in certain circumstances such as that of emitting DDL. In order to access this functionality one can use the 'literal_binds' flag, passed to compile_kwargs:

from sqlalchemy.sql import table, column, select

t = table('t', column('x'))

s = select([t]).where(t.c.x == 5)

print(s.compile(compile_kwargs={"literal_binds": True}))

the above approach has the caveats that it is only supported for basic types, such as ints and strings, and furthermore if a bindparam without a pre-set value is used directly, it won't be able to stringify that either.

To support inline literal rendering for types not supported, implement a TypeDecorator for the target type which includes a TypeDecorator.process_literal_param method:

from sqlalchemy import TypeDecorator, Integer


class MyFancyType(TypeDecorator):
    impl = Integer

    def process_literal_param(self, value, dialect):
        return "my_fancy_formatting(%s)" % value

from sqlalchemy import Table, Column, MetaData

tab = Table('mytable', MetaData(), Column('x', MyFancyType()))

print(
    tab.select().where(tab.c.x > 5).compile(
        compile_kwargs={"literal_binds": True})
)

producing output like:

SELECT mytable.x
FROM mytable
WHERE mytable.x > my_fancy_formatting(5)

I've found that this can happen due to a number of various reasons.

In my case when I scroll to the end of the SQL import "Report", under the "Post-execute (Success)" heading it will tell me how many rows were copied and it's usually the next row in sheet which has the issue. Also you can tell which column by the import messages (in your case it was "Copy of F2") so you can generally find out which was the offending cell in Excel.

I've seen this happen for very silly reasons such as the date format in Excel being different than previous rows. For example cell A2 being "05/02/2017" while A3 being "5/2/2017" or even "05-02-2017". It seems the import wants things to be perfectly consistent.

It even happens if the Excel formats are different so if B2 is "512" but an Excel "Number" format and B3 is "512" but an Excel "Text" format then the Cell will cause an error.

I've also had situations where I literally had to delete all the "empty" rows below my data rows in the Excel sheet. Sometimes they appear empty but Excel considers them having "blank" data or something like that so the import tries to import them as well. This usually happens if you've had previous data in your Excel sheet which you've cleared but haven't properly deleted the rows.

And then there's the obvious reasons of trying to import text value into an integer column or insert a NULL into a NOT NULL column as mentioned by the others.

Rclone is what you are looking for. Rclone ("rsync for cloud storage") is a command line program to sync files and directories to and from different cloud storage providers including local filesystems. Rclone was previously known as Swiftsync and has been available since 2013.

The problem can be PHP configuration:

Please check the setting max_input_vars in the php.ini file.

Try to increase the value of this setting to 5000 as example.

max_input_vars = 5000

Then restart your web-server and try.

try this:

self.view.layer.zPosition = 1;

In older versions you could use attr. As of jQuery 1.6 you should use prop instead:

$("#target :input").prop("disabled", true);

To disable all form elements inside 'target'. See :input:

Matches all input, textarea, select and button elements.

If you only want the <input> elements:

$("#target input").prop("disabled", true);

sudo apt install adb

in your pc adb not installed.

Try this, working for me

If you are using 'docker-compose' as the method to spin up your container(s), there is actually a useful way to pass an environment variable defined on your server to the Docker container.

In your docker-compose.yml file, let's say you are spinning up a basic hapi-js container and the code looks like:

hapi_server:
  container_name: hapi_server
  image: node_image
  expose:
    - "3000"

Let's say that the local server that your docker project is on has an environment variable named 'NODE_DB_CONNECT' that you want to pass to your hapi-js container, and you want its new name to be 'HAPI_DB_CONNECT'. Then in the docker-compose.yml file, you would pass the local environment variable to the container and rename it like so:

hapi_server:
  container_name: hapi_server
  image: node_image
  environment:
    - HAPI_DB_CONNECT=${NODE_DB_CONNECT}
  expose:
    - "3000"

I hope this helps you to avoid hard-coding a database connect string in any file in your container!

For Kotlin you can use

val myIntent = Intent(activity, your_destination_activity::class.java)
startActivity(myIntent)
