Programs & Examples On #Zepto

I was having same issue when I was receiving array of objects in django sent by ajax. JSONStringyfy worked for me. You can have a look for this.

First I stringify the data as

var myData = [];
   allData.forEach((x, index) => {
         // console.log(index);
         myData.push(JSON.stringify({
         "product_id" : x.product_id,
         "product" : x.product,
         "url" : x.url,
         "image_url" : x.image_url,
         "price" : x.price,
         "source": x.source
      }))
   })

Then I sent it like

$.ajax({
        url: '{% url "url_name" %}',
        method: "POST",
        data: {
           'csrfmiddlewaretoken': '{{ csrf_token }}',
           'queryset[]': myData
        },
        success: (res) => {
        // success post work here.
    }
})

And received as :

list_of_json = request.POST.getlist("queryset[]", [])
list_of_json = [ json.loads(item) for item in list_of_json ]

in pure js just use offsetLeft and offsetTop properties.
Example fiddle: http://jsfiddle.net/WKZ8P/

var elm = document.querySelector('span');_x000D_
console.log(elm.offsetLeft, elm.offsetTop);

p   { position:relative; left:10px; top:85px; border:1px solid blue; }_x000D_
span{ position:relative; left:30px; top:35px; border:1px solid red; }

<p>_x000D_
    <span>paragraph</span>_x000D_
</p>

In my case

android studio suddenly stop seeing my device

I fix it by change USB option to Media device (MTP)

how to get USB option from storage USB Computer Connection

check Debugging from developer options

try re-run on device , it should work

issue

USB option was charge only

UPDATE ANSWER 26/7/2016

there many reasons like not enabling developer mode --> USB debugging(if you dont see developer option click 7 times at build number )

but I face another issue every thing was works just fine suddenly android studio cant see my device

to fix this issue you need to restart adb , from terminal

adb kill-server
adb start-server

or from ddms

in devices section --> click at small arrow down --> restart adb

well, the term "url encoded" is a bit vague, perhaps simple regex check will do the trick

$is_encoded = preg_match('~%[0-9A-F]{2}~i', $string);

I know this is kinda an old question but:

root["bg"] = "black"

will also do what you want and it involves less typing.

I usually do it using Seaborn which is built on top of matplotlib

import seaborn as sns
iris = sns.load_dataset('iris')
sns.scatterplot(x='sepal_length', y='sepal_width',
              hue='species', data=iris); 

Alex's answer shows you a solution for standard normal distribution (mean = 0, standard deviation = 1). If you have normal distribution with mean and std (which is sqr(var)) and you want to calculate:

from scipy.stats import norm

# cdf(x < val)
print norm.cdf(val, m, s)

# cdf(x > val)
print 1 - norm.cdf(val, m, s)

# cdf(v1 < x < v2)
print norm.cdf(v2, m, s) - norm.cdf(v1, m, s)

Read more about cdf here and scipy implementation of normal distribution with many formulas here.

Additionally, for our Android friends (API Level 8):

import android.util.Base64

...

Base64.encodeToString(bytes, Base64.DEFAULT);

Database Input - How to prevent SQL Injection

1. Check to make sure data of type integer, for example, is valid by ensuring it actually is an integer
   • In the case of non-strings you need to ensure that the data actually is the correct type
   • In the case of strings you need to make sure the string is surrounded by quotes in the query (obviously, otherwise it wouldn't even work)
2. Enter the value into the database while avoiding SQL injection (mysql_real_escape_string or parameterized queries)
3. When Retrieving the value from the database be sure to avoid Cross Site Scripting attacks by making sure HTML can't be injected into the page (htmlspecialchars)

You need to escape user input before inserting or updating it into the database. Here is an older way to do it. You would want to use parameterized queries now (probably from the PDO class).

$mysql['username'] = mysql_real_escape_string($clean['username']);
$sql = "SELECT * FROM userlist WHERE username = '{$mysql['username']}'";
$result = mysql_query($sql);

Output from database - How to prevent XSS (Cross Site Scripting)

Use htmlspecialchars() only when outputting data from the database. The same applies for HTML Purifier. Example:

$html['username'] = htmlspecialchars($clean['username'])

• Buy this book if you can: Essential PHP Security
• Also read this article: Why mysql_real_escape_string is important and some gotchas

And Finally... what you requested

I must point out that if you use PDO objects with parameterized queries (the proper way to do it) then there really is no easy way to achieve this easily. But if you use the old 'mysql' way then this is what you would need.

function filterThis($string) {
    return mysql_real_escape_string($string);
}

You just need to check whether the file is there, by typing

cat /etc/apache2/mods-available/rewrite.load

The result line may not be commented starting with #

import * as utils from './utils.js'; 

If you do the above, you will be able to use functions in utils.js as

utils.someFunction()

Write lock on shared local repository

I had this problem and none of above advises helped me. I was able to fetch everything correctly. But push always failed. It was a local repository located on windows directory with several clients working with it through VMWare shared folder driver. It appeared that one of the systems locked Git repository for writing. After stopping relevant VMWare system, which caused the lock everything repaired immediately. It was almost impossible to figure out, which system causes the error, so I had to stop them one by one until succeeded.

In order to trap repeated clicks on the same cell, you need to move the focus to a different cell, so that each time you click, you are in fact moving the selection.

The code below will select the top left cell visible on the screen, when you click on any cell. Obviously, it has the flaw that it won't trap a click on the top left cell, but that can be managed (eg by selecting the top right cell if the activecell is the top left).

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  'put your code here to process the selection, then..
  ActiveWindow.VisibleRange.Cells(1, 1).Select
End Sub

If you use a JSONB field, you must convert it to JSON with .to_json (ROR)

Just for the records the analogous java version:

Tuple2<String, String> sc[] = sparkConf.getAll();
for (int i = 0; i < sc.length; i++) {
    System.out.println(sc[i]);
}

You can update two tables in one query.

UPDATE Table1, Table2 
SET Table1.LastName="DR. XXXXXX", Table2.WAprrs="start,stop" 
WHERE Table1.id=Table2.id AND Table1.id="010008";

please use this code for input text

$('#search').on("input",function (e) {});

if you use .on("change",function (e) {}); then you need to blur input

if you use .on("keyup",function (e) {}); then you get value before the last character you typed

(function variableInterval() {
    //whatever needs to be done
    interval *= 2; //deal with your interval
    setTimeout(variableInterval, interval);
    //whatever needs to be done
})();

can't get any shorter

Two options:

<button>multiline<br/>button<br/>text</button>

or

 <input type="button" value="Carriage&#13;&#10;return&#13;&#10;separators" style="text-align:center;">

If you want to create a .war file you can deploy to a Tomcat instance using the Manager app, create a folder, put all your files in that folder (including an index.html file) move your terminal window into that folder, and execute the following command:

zip -r <AppName>.war *

I've tested it with Tomcat 8 on the Mac, but it should work anywhere

    //UIColorWithHexString

    static UIColor * UIColorWithHexString(NSString *hex) {
        unsigned int rgb = 0;
        [[NSScanner scannerWithString:
          [[hex uppercaseString] stringByTrimmingCharactersInSet:
           [[NSCharacterSet characterSetWithCharactersInString:@"0123456789ABCDEF"] invertedSet]]]
         scanHexInt:&rgb];
        return [UIColor colorWithRed:((CGFloat)((rgb & 0xFF0000) >> 16)) / 255.0
                               green:((CGFloat)((rgb & 0xFF00) >> 8)) / 255.0
                                blue:((CGFloat)(rgb & 0xFF)) / 255.0
                               alpha:1.0];
    }

Usage

self.view.backgroundColor = UIColorWithHexString(@"#0F35C0");

I found the same thing: curl by itself would print to STDOUT, but could not be piped into another program.

At first, I thought I had solved it by using xargs to echo the output first:

curl -s ... <url> | xargs -0 echo | ...

But then, as pointed out in the comments, it also works without the xargs part, so -s (silent mode) is the key to preventing extraneous progress output to STDOUT:

curl -s ... <url> | perl  -ne 'print $1 if /<sometag>([^<]+)/'

The above example grabs the simple <sometag> content (containing no embedded tags) from the XML output of the curl statement.

First add the new files:

svn add fileName

Then commit all new and modified files

svn ci <files_separated_by_space> -m "Commit message|ReviewID:XXXX"

If non source files are to be committed then

svn ci <files> -m "Commit msg|ReviewID:NON-SOURCE"

You can always create a new Eclipse workspace. The Eclipse.exe -clean option is not sufficient in some cases, for example, if the local history becomes a problem.

Edit:

Eclipse is mostly a collection of third party plugins. And each of those plugins can add some extra useful, useless or problematic information to the central Eclipse workspace meta-data folder.

The problem is that not every plugin participates during the user-issued cleanup routine. Therefore, I'd say that it is a problem in the system design of Eclipse, that it allows plugins to misbehave like this.

And therefore, I'd recommend to make yourself comfortable with the idea of using multiple workspaces and linking-in external project entities into each workspace. Because, this is the only workaround for the given system design, to handle faulty plugins that spam your workspace.

It is not good practice to hard code strings into your layout files. You should add them to a string resource file and then reference them from your layout.

This allows you to update every occurrence of the word "Yellow" in all layouts at the same time by just editing your strings.xml file.

It is also extremely useful for supporting multiple languages as a separate strings.xml file can be used for each supported language.

example: XML file saved at res/values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="yellow">Yellow</string>
</resources>

This layout XML applies a string to a View:

<TextView android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:text="@string/yellow" />

Similarly colors should be stored in colors.xml and then referenced by using @color/color_name

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="Black">#000000</color>
</resources>

this is because the return type of your method is int and OrdersPerHour is int? (nullable) , you can solve this by returning its value like below:

return OrdersPerHour.Value

also check if its not null to avoid exception like as below:

if(OrdersPerHour != null)
{

    return OrdersPerHour.Value;

}
else
{

  return 0; // depends on your choice

}

but in this case you will have to return some other value in the else part or after the if part otherwise compiler will flag an error that not all paths of code return value.

I'm a bit of a beginner and struggled getting this to work today.

Below is the class that I ended up with. It works but I was wondering how imperfect my solution is. Anyway, I was hoping some of you more experienced folk might be willing to have a look at my IO class and give me some tips. Cheers!

public class HighScore {
    File data = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator);
    File file = new File(data, "highscore.txt");
    private int highScore = 0;

    public int readHighScore() {
        try {
            BufferedReader br = new BufferedReader(new FileReader(file));
            try {
                highScore = Integer.parseInt(br.readLine());
                br.close();
            } catch (NumberFormatException | IOException e) {
                e.printStackTrace();
            }
        } catch (FileNotFoundException e) {
            try {
                file.createNewFile();
            } catch (IOException ioe) {
                ioe.printStackTrace();
            }
            e.printStackTrace();
        }
        return highScore;
    }

    public void writeHighScore(int highestScore) {
        try {
            BufferedWriter bw = new BufferedWriter(new FileWriter(file));
            bw.write(String.valueOf(highestScore));
            bw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Its best to use auto on the dimension that should respect the aspect ratio. If you do not set the other property to auto, most browsers nowadays will assume that you want to respect the aspect ration, but not all of them (IE10 on windows phone 8 does not, for example)

width: 100%;
height: auto;

You can also use a block if you have multiple columns to change within a table.

Example:

change_table :table_name do |t|
  t.change :column_name, :column_type, {options}
end

See the API documentation on the Table class for more details.

Few people appear, despite the many answers to this question, to have pointed out that dictionaries are un-ordered mappings, and so (until the blessing of insertion order with Python 3.7) the idea of the "first" entry in a dictionary literally made no sense. And even an OrderedDict can only be accessed by numerical index using such uglinesses as mydict[mydict.keys()[0]] (Python 2 only, since in Python 3 keys() is a non-subscriptable iterator.)

From 3.7 onwards and in practice in 3,6 as well - the new behaviour was introduced then, but not included as part of the language specification until 3.7 - iteration over the keys, values or items of a dict (and, I believe, a set also) will yield the least-recently inserted objects first. There is still no simple way to access them by numerical index of insertion.

As to the question of selecting and "formatting" items, if you know the key you want to retrieve in the dictionary you would normally use the key as a subscript to retrieve it (my_var = mydict['Apple']).

If you really do want to be able to index the items by entry number (ignoring the fact that a particular entry's number will change as insertions are made) then the appropriate structure would probably be a list of two-element tuples. Instead of

mydict = {
  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
  'Grapes':{'Arabian':'25','Indian':'20'} }

you might use:

mylist = [
    ('Apple', {'American':'16', 'Mexican':10, 'Chinese':5}),
    ('Grapes', {'Arabian': '25', 'Indian': '20'}
]

Under this regime the first entry is mylist[0] in classic list-endexed form, and its value is ('Apple', {'American':'16', 'Mexican':10, 'Chinese':5}). You could iterate over the whole list as follows:

for (key, value) in mylist:  # unpacks to avoid tuple indexing
    if key == 'Apple':
        if 'American' in value:
            print(value['American'])

but if you know you are looking for the key "Apple", why wouldn't you just use a dict instead?

You could introduce an additional level of indirection by cacheing the list of keys, but the complexities of keeping two data structures in synchronisation would inevitably add to the complexity of your code.

As per official documentation link shared by Andre Kirpitch, Oracle 10g gives a maximum size of 4000 bytes or characters for varchar2. If you are using a higher version of oracle (for example Oracle 12c), you can get a maximum size upto 32767 bytes or characters for varchar2. To utilize the extended datatype feature of oracle 12, you need to start oracle in upgrade mode. Follow the below steps in command prompt:

1) Login as sysdba (sqlplus / as sysdba)

2) SHUTDOWN IMMEDIATE;

3) STARTUP UPGRADE;

4) ALTER SYSTEM SET max_string_size=extended;

5) Oracle\product\12.1.0.2\rdbms\admin\utl32k.sql

6) SHUTDOWN IMMEDIATE;

7) STARTUP;

Usinge the file argument in the print function, you can have different files per print:

print('Redirect output to file', file=open('/tmp/example.log', 'w'))

In my case the problem was happening because the class I created had a namespace that interfered with existing classes. The new class A had namespace zz.yy.xx (by mistake). References to objects in another namespace yy.xx were not compiling in class A or other classes whose namespace was zz.

I changed the namespace of class A to yy.xx , which it should have been, and it started working.

Here is a basic example that explains the callback() function in JavaScript:

var x = 0;_x000D_
_x000D_
function testCallBack(param1, param2, callback) {_x000D_
  alert('param1= ' + param1 + ', param2= ' + param2 + ' X=' + x);_x000D_
  if (callback && typeof(callback) === "function") {_x000D_
    x += 1;_x000D_
    alert("Calla Back x= " + x);_x000D_
    x += 1;_x000D_
    callback();_x000D_
  }_x000D_
}_x000D_
_x000D_
testCallBack('ham', 'cheese', function() {_x000D_
  alert("Function X= " + x);_x000D_
});

the nuget package Selenium.Support already contains an extension method to help with this. Once it is included, one liner to executer script

  Driver.ExecuteJavaScript("console.clear()");

or

  string result = Driver.ExecuteJavaScript<string>("console.clear()");

You could use a pseudo element for this, and have your image on a hover:

.image {_x000D_
  position: relative;_x000D_
  height: 300px;_x000D_
  width: 300px;_x000D_

Work out the solution according to what you want...

There are two things that getResource/getResourceAsStream() will get from the class it is called on...

1. The class loader
2. The starting location

So if you do

this.getClass().getResource("foo.txt");

it will attempt to load foo.txt from the same package as the "this" class and with the class loader of the "this" class. If you put a "/" in front then you are absolutely referencing the resource.

this.getClass().getResource("/x/y/z/foo.txt")

will load the resource from the class loader of "this" and from the x.y.z package (it will need to be in the same directory as classes in that package).

Thread.currentThread().getContextClassLoader().getResource(name)

will load with the context class loader but will not resolve the name according to any package (it must be absolutely referenced)

System.class.getResource(name)

Will load the resource with the system class loader (it would have to be absolutely referenced as well, as you won't be able to put anything into the java.lang package (the package of System).

Just take a look at the source. Also indicates that getResourceAsStream just calls "openStream" on the URL returned from getResource and returns that.

Open config file to edit :

git config --global --edit

Press Insert and remove the setting

and finally type :wq and Enter to save.

Change

id.equals(list[pos].getItemNumber())

to

id == list[pos].getItemNumber()

For more details, you should learn the difference between the primitive types like int, char, and double and reference types.

If you're trying to run a program using a scripting language, you may need to include the full path of the scripting language and the file to execute. For example:

exec('/usr/local/bin/node /usr/local/lib/node_modules/uglifycss/uglifycss in.css > out.css');

What may be happening is that your console is closing before you get a chance to see the output. I would add Console.ReadLine(); after your Console.WriteLine("Hello World"); so your code would look something like this:

static void Main(string[] args)
    {
        Console.WriteLine("Hello World");
        Console.ReadLine();

    }

This way, the console will display "Hello World" and a blinking cursor underneath. The Console.ReadLine(); is the key here, the program waits for the users input before closing the console window.

I have used Excel.dll library which is:

• open source
• lightweight
• fast
• compatible with xls and xlsx

The documentation available over here: https://exceldatareader.codeplex.com/

Strongly recommendable.

Not the actual issue here, but might help some one: I was doing awk "{print $NF}", note the wrong quotes. Should be awk '{print $NF}', so that the shell doesn't expand $NF.

Try this:

$('[id$=lblVessel]').text("NewText");

The id$= will match the elements that end with that text, which is how ASP.NET auto-generates IDs. You can make it safer using span[id=$=lblVessel] but usually this isn't necessary.

It looks to me as though the basic problem is that you have one wait() call rather than a loop that waits until there are no more children. You also only wait if the last fork() is successful rather than if at least one fork() is successful.

You should only use _exit() if you don't want normal cleanup operations - such as flushing open file streams including stdout. There are occasions to use _exit(); this is not one of them. (In this example, you could also, of course, simply have the children return instead of calling exit() directly because returning from main() is equivalent to exiting with the returned status. However, most often you would be doing the forking and so on in a function other than main(), and then exit() is often appropriate.)

Hacked, simplified version of your code that gives the diagnostics I'd want. Note that your for loop skipped the first element of the array (mine doesn't).

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/wait.h>

int main(void)
{
    pid_t child_pid, wpid;
    int status = 0;
    int i;
    int a[3] = {1, 2, 1};

    printf("parent_pid = %d\n", getpid());
    for (i = 0; i < 3; i++)
    {
        printf("i = %d\n", i);
        if ((child_pid = fork()) == 0)
        {
            printf("In child process (pid = %d)\n", getpid());
            if (a[i] < 2)
            {
                printf("Should be accept\n");
                exit(1);
            }
            else
            {
                printf("Should be reject\n");
                exit(0);
            }
            /*NOTREACHED*/
        }
    }

    while ((wpid = wait(&status)) > 0)
    {
        printf("Exit status of %d was %d (%s)\n", (int)wpid, status,
               (status > 0) ? "accept" : "reject");
    }
    return 0;
}

Example output (MacOS X 10.6.3):

parent_pid = 15820
i = 0

In child process (pid = 15821)
Should be accept
i = 2
In child process (pid = 15822)
Should be reject
In child process (pid = 15823)
Should be accept
Exit status of 15823 was 256 (accept)
Exit status of 15822 was 0 (reject)
Exit status of 15821 was 256 (accept)

A simple example is

2 == '2'  -> true, values are SAME because of type conversion.

2 === '2'  -> false, values are NOT SAME because of no type conversion.

Try this:

HTML:

<input type="checkbox" value="FALSE" />

jQ:

$("input[type='checkbox']").on('change', function(){
  $(this).val(this.checked ? "TRUE" : "FALSE");
})

Please bear in mind that unchecked checkbox will not be submitted in regular form, and you should use hidden filed in order to do it.

Did you implement the main() function?

int main(int argc, char **argv) {
    ... code ...
    return 0;
}

[edit]

You have your main() in another source file so you've probably forgotten to add it to your project.

To add an existing source file: In Solution Explorer, right-click the Source Files folder, point to Add, and then click Existing Item. Now select the source file containing the main()

Try this:

$ git apply file.diff

I have just sent an email with gmail through Python. Try to use smtplib.SMTP_SSL to make the connection. Also, you may try to change the gmail domain and port.

So, you may get a chance with:

server = smtplib.SMTP_SSL('smtp.googlemail.com', 465)
server.login(gmail_user, password)
server.sendmail(gmail_user, TO, BODY)

As a plus, you could check the email builtin module. In this way, you can improve the readability of you your code and handle emails headers easily.

Is there any 64 bit Visual Studio at all?

Yes literally there is one called "Visual Studio" and is 64bit, but well,, on Mac not on Windows

Why not?

Decision making is electro-chemical reaction made in our brain and that have an activation point (Nerdest answer I can come up with, but follow). Same situation happened in history: Windows 64!...

So in order to answer this fully I want you to remember old days. Imagine reasons for "why not we see 64bit Windows" are there at the time. I think at the time for Windows64 they had exact same reasons others have enlisted here about "reasons why not 64bit VS on windows" were on "reasons why not 64bit Windows" too. Then why they did start development for Windows 64bit? Simple! If they didn't succeed in making 64bit Windows I bet M$ would have been a history nowadays. If same reasons forcing M$ making 64bit Windows starts to appear on need for 64Bit VS then I bet we will see 64bit VS, even though very same reasons everyone else here enlisted will stay same! In time the limitations of 32bit may hit VS as well, so most likely something like below start to happen:

• Visual Studio will drop 32bit support and become 64bit,
• Visual Studio Code will take it's place instead,
• Visual Studio will have similar functionality like WOW64 for old extensions which is I believe unlikely to happen.

I put my bets on Visual Studio Code taking the place in time; I guess bifurcation point for it will be some CPU manufacturer X starts to compete x86_64 architecture taking its place on mainstream market for laptop and/or workstation,

In regards to iterative variable names, I like making dynamic variables using Template literals. Every Tom, Dick, and Harry uses the array-style, which is fine. Until you're working with arrays and dynamic variables, oh boy! Eye-bleed overload. Since Template literals have limited support right now, eval() is even another option.

v0 = "Variable Naught";
v1 = "Variable One";

for(i = 0; i < 2; i++)
{//console.log(i) equivalent is console.log(`${i}`)
  dyV = eval(`v${i}`);
  console.log(`v${i}`); /* => v0;   v1;  */      
  console.log(dyV);  /* => Variable Naught; Variable One;  */
}

When I was hacking my way through the APIs I made this little looping snippet to see behavior depending on what was done with the Template literals compared to say, Ruby. I liked Ruby's behavior more; needing to use eval() to get the value is kind of lame when you're used to getting it automatically.

_0 = "My first variable"; //Primitive
_1 = {"key_0":"value_0"}; //Object
_2 = [{"key":"value"}]    //Array of Object(s)


for (i = 0; i < 3; i++)
{
  console.log(`_${i}`);           /*  var
                                   * =>   _0  _1  _2  */

  console.log(`"_${i}"`);         /*  var name in string  
                                   * => "_0"  "_1"  "_2"  */

  console.log(`_${i}` + `_${i}`); /*  concat var with var
                                   * => _0_0  _1_1  _2_2  */

  console.log(eval(`_${i}`));     /*  eval(var)
                                   * => My first variable
                                        Object {key_0: "value_0"}
                                        [Object]  */
}

When there is more than one module under app folder, generating a component with below command will fail:

ng generate component New-Component-Name

The reason is angular CLI detects multiple module, and does't know in which module to add the component. So, you need to explicitly mention which module component will be added:

ng generate component New-Component-Name --module=ModuleName

This is how I restore RecyclerView position with GridLayoutManager after rotation when you need to reload data from internet with AsyncTaskLoader.

Make a global variable of Parcelable and GridLayoutManager and a static final string:

private Parcelable savedRecyclerLayoutState;
private GridLayoutManager mGridLayoutManager;
private static final String BUNDLE_RECYCLER_LAYOUT = "recycler_layout";

Save state of gridLayoutManager in onSaveInstance()

 @Override
        protected void onSaveInstanceState(Bundle outState) {
            super.onSaveInstanceState(outState);
            outState.putParcelable(BUNDLE_RECYCLER_LAYOUT, 
            mGridLayoutManager.onSaveInstanceState());
        }

Restore in onRestoreInstanceState

@Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);

        //restore recycler view at same position
        if (savedInstanceState != null) {
            savedRecyclerLayoutState = savedInstanceState.getParcelable(BUNDLE_RECYCLER_LAYOUT);
        }
    }

Then when loader fetches data from internet you restore recyclerview position in onLoadFinished()

if(savedRecyclerLayoutState!=null){
                mGridLayoutManager.onRestoreInstanceState(savedRecyclerLayoutState);
            }

..of course you have to instantiate gridLayoutManager inside onCreate. Cheers

Although I would personally use a with statement to handle opening and closing a file, in the case where you have to read from stdin and need to track an EOF exception, do something like this:

Use a try-catch with EOFError as the exception:

try:
    input_lines = ''
    for line in sys.stdin.readlines():
        input_lines += line             
except EOFError as e:
    print e

Perhaps the sched module will meet your needs.

Alternatively, consider using a Timer object.

1. Add folders to your project and add images to these through "Existing Item".
2. XAML similar to this: <Image Source="MyRessourceDir\images\addButton.png"/>
3. F6 (Build)

There are (at least) two different ways to get to theWorksheet object

• via the Sheets or Worksheets collections as referenced by DanM
• by unqualified object names

When a new workbook with three worksheets is created there will exist four objects which you can access via unqualified names: ThisWorkbook; Sheet1; Sheet2; Sheet3. This lets you write things like this:

Sheet1.Range("A1").Value = "foo"

Although this may seem like a useful shortcut, the problem comes when the worksheets are renamed. The unqualified object name remains as Sheet1 even if the worksheet is renamed to something totally different.

There is some logic to this because:

• worksheet names don't conform to the same rules as variable names
• you might accidentally mask an existing variable

For example (tested in Excel 2003), create a new Workbook with three worksheets. Create two modules. In one module declare this:

Public Sheet4 As Integer

In the other module put:

Sub main()

Sheet4 = 4

MsgBox Sheet4

End Sub

Run this and the message box should appear correctly.

Now add a fourth worksheet to the workbook which will create a Sheet4 object. Try running main again and this time you will get an "Object does not support this property or method" error

You can also use git diff HEAD file to show the diff for a specific file.

If you actually create the buffer as per dirks suggestion, then:

  int readResult = read(socketFileDescriptor, buffer, BUFFER_SIZE);

may completely fill the buffer, possibly overwriting the terminating zero character which you depend on when extracting to a stringstream. You need:

  int readResult = read(socketFileDescriptor, buffer, BUFFER_SIZE - 1 );

There is no such limit on the string length. To be certain, I just tested to create a string containing 60 megabyte.

The problem is likely that you are sending the data in a GET request, so it's sent in the URL. Different browsers have different limits for the URL, where IE has the lowest limist of about 2 kB. To be safe, you should never send more data than about a kilobyte in a GET request.

To send that much data, you have to send it in a POST request instead. The browser has no hard limit on the size of a post, but the server has a limit on how large a request can be. IIS for example has a default limit of 4 MB, but it's possible to adjust the limit if you would ever need to send more data than that.

Also, you shouldn't use += to concatenate long strings. For each iteration there is more and more data to move, so it gets slower and slower the more items you have. Put the strings in an array and concatenate all the items at once:

var items = $.map(keys, function(item, i) {
  var value = $("#value" + (i+1)).val().replace(/"/g, "\\\"");
  return
    '{"Key":' + '"' + Encoder.htmlEncode($(this).html()) + '"' + ",'+
    '" + '"Value"' + ':' + '"' + Encoder.htmlEncode(value) + '"}';
});
var jsonObj =
  '{"code":"' + code + '",'+
  '"defaultfile":"' + defaultfile + '",'+
  '"filename":"' + currentFile + '",'+
  '"lstResDef":[' + items.join(',') + ']}';

if (/^\s+$/.test(myString))
{
      //string contains only whitespace
}

this checks for 1 or more whitespace characters, if you it to also match an empty string then replace + with *.

Parts of the GCC runtime (the exception handling, in particular) are dependent on the threading model being used. So, if you're using the version of the runtime that was built with POSIX threads, but decide to create threads in your own code with the Win32 APIs, you're likely to have problems at some point.

Even if you're using the Win32 threading version of the runtime you probably shouldn't be calling the Win32 APIs directly. Quoting from the MinGW FAQ:

As MinGW uses the standard Microsoft C runtime library which comes with Windows, you should be careful and use the correct function to generate a new thread. In particular, the CreateThread function will not setup the stack correctly for the C runtime library. You should use _beginthreadex instead, which is (almost) completely compatible with CreateThread.

I find this approach a bit more flexible, here you just providing generator function that emits key, value pairs and can be easily extended to also iterate over lists.

def traverse(value, key=None):
    if isinstance(value, dict):
        for k, v in value.items():
            yield from traverse(v, k)
    else:
        yield key, value

Then you can write your own myprint function, then would print those key value pairs.

def myprint(d):
    for k, v in traverse(d):
        print(f"{k} : {v}")

A test:

myprint({
    'xml': {
        'config': {
            'portstatus': {
                'status': 'good',
            },
            'target': '1',
        },
        'port': '11',
    },
})

Output:

status : good
target : 1
port : 11

I tested this on Python 3.6.

In this case, you could use life to reference the parent object. Or you could store a reference to life in the users object. There can't be a fixed parent available to you in the language, because users is just a reference to an object, and there could be other references...

var death = { residents : life.users };
life.users.smallFurryCreaturesFromAlphaCentauri = { exist : function() {} };
// death.residents.smallFurryCreaturesFromAlphaCentauri now exists
//  - because life.users references the same object as death.residents!

You might find it helpful to use something like this:

function addChild(ob, childName, childOb)
{
   ob[childName] = childOb;
   childOb.parent = ob;
}

var life= {
        mameAndDestroy : function(group){ },
        kiss : function(group){ }
};

addChild(life, 'users', {
   guys : function(){ this.parent.mameAndDestroy(this.girls); },
   girls : function(){ this.parent.kiss(this.boys); },
   });

// life.users.parent now exists and points to life

For MySQL 5.7 on Mac OS X El Capitan:

OS X provides example configuration files at /usr/local/mysql/support-files/my-default.cnf

To add variables, first stop the server and just copy above file to, /usr/local/mysql/etc/my.cnf

cmd : sudo cp /usr/local/mysql/support-files/my-default.cnf /usr/local/mysql/etc/my.cnf

NOTE: create 'etc' folder under 'mysql' in case it doesn't exists.

cmd : sudo mkdir /usr/local/mysql/etc

Once the my.cnf is created under etc. it's time to set variable inside that.

cmd: sudo nano my.cnf

set variables below [mysqld]

[mysqld]
innodb_log_file_size = 512M
innodb_strict_mode = 0

now start a server!

Its also important to note that you will lose the chronological stack trace of the exception if you you have a void return type on an async method. I would recommend returning Task as follows. Going to make debugging a whole lot easier.

public async Task DoFoo()
    {
        try
        {
            return await Foo();
        }
        catch (ProtocolException ex)
        {
            /* Exception with chronological stack trace */     
        }
    }

Python has docstrings and ruby doesn't... Or if it doesn't, they are not accessible as easily as in python.

Ps. If im wrong, pretty please, leave an example? I have a workaround that i could monkeypatch into classes quite easily but i'd like to have docstring kinda of a feature in "native way".

This is another method in addition to my previous answer at Can I add jars to maven 2 build classpath without installing them?

This will get around the limit when using multi-module builds especially if the downloaded JAR is referenced in child projects outside of the parent. This also reduces the setup work by creating the POM and the SHA1 files as part of the build. It also allows the file to reside anywhere in the project without fixing the names or following the maven repository structure.

This uses the maven-install-plugin. For this to work, you need to set up a multi-module project and have a new project representing the build to install files into the local repository and ensure that one is first.

You multi-module project pom.xml would look like this:

<packaging>pom</packaging>
<modules>
<!-- The repository module must be first in order to ensure
     that the local repository is populated -->
    <module>repository</module>
    <module>... other modules ...</module>
</modules>

The repository/pom.xml file will then contain the definitions to load up the JARs that are part of your project. The following are some snippets of the pom.xml file.

<artifactId>repository</artifactId>
<packaging>pom</packaging>

The pom packaging prevents this from doing any tests or compile or generating any jar file. The meat of the pom.xml is in the build section where the maven-install-plugin is used.

<build>
    <plugins>
        <plugin>

                            <artifactId>db2jcc</artifactId>
                            <version>9.0.0</version>
                            <packaging>jar</packaging>
                            <file>${basedir}/src/jars/db2jcc.jar</file>
                            <createChecksum>true</createChecksum>
                            <generatePom>true</generatePom>
                        </configuration>
                </execution>
                <execution>...</execution>
            </executions>
        </plugin>
    </plugins>
</build>

To install more than one file, just add more executions.

How to do this was added to the official Django docs in Django1.4

https://docs.djangoproject.com/en/1.10/topics/db/queries/#copying-model-instances

The official answer is similar to miah's answer, but the docs point out some difficulties with inheritance and related objects, so you should probably make sure you read the docs.

I prefer the following, which is cleaner:

x = [1, 2, 3];
g=sprintf('%d ', x);
fprintf('Answer: %s\n', g)

which outputs

Answer: 1 2 3

Use:

'00'[len(str(i)):] + str(i)

Or with the math module:

import math
'00'[math.ceil(math.log(i, 10)):] + str(i)

There is also this one:

hash = { foo: "bar", baz: "qux" }
hash.map(&:last) #=> ["bar", "qux"]

Why it works:

The & calls to_proc on the object, and passes it as a block to the method.

something {|i| i.foo }
something(&:foo)

This is quite simple: my_data is a before defined structure type. So you want to declare an my_data-array of some elements, as you would do with

char a[] = { 'a', 'b', 'c', 'd' };

So the array would have 4 elements and you initialise them as

a[0] = 'a', a[1] = 'b', a[1] = 'c', a[1] ='d';

This is called a designated initializer (as i remember right).

and it just indicates that data has to be of type my_dat and has to be an array that needs to store so many my_data structures that there is a structure with each type member name Peter, James, John and Mike.

See populate a database in the PostgreSQL manual, depesz's excellent-as-usual article on the topic, and this SO question.

(Note that this answer is about bulk-loading data into an existing DB or to create a new one. If you're interested DB restore performance with pg_restore or psql execution of pg_dump output, much of this doesn't apply since pg_dump and pg_restore already do things like creating triggers and indexes after it finishes a schema+data restore).

There's lots to be done. The ideal solution would be to import into an UNLOGGED table without indexes, then change it to logged and add the indexes. Unfortunately in PostgreSQL 9.4 there's no support for changing tables from UNLOGGED to logged. 9.5 adds ALTER TABLE ... SET LOGGED to permit you to do this.

If you can take your database offline for the bulk import, use pg_bulkload.

Otherwise:

• Disable any triggers on the table

• Drop indexes before starting the import, re-create them afterwards. (It takes much less time to build an index in one pass than it does to add the same data to it progressively, and the resulting index is much more compact).

• If doing the import within a single transaction, it's safe to drop foreign key constraints, do the import, and re-create the constraints before committing. Do not do this if the import is split across multiple transactions as you might introduce invalid data.

• If possible, use COPY instead of INSERTs

• If you can't use COPY consider using multi-valued INSERTs if practical. You seem to be doing this already. Don't try to list too many values in a single VALUES though; those values have to fit in memory a couple of times over, so keep it to a few hundred per statement.

• Batch your inserts into explicit transactions, doing hundreds of thousands or millions of inserts per transaction. There's no practical limit AFAIK, but batching will let you recover from an error by marking the start of each batch in your input data. Again, you seem to be doing this already.

• Use synchronous_commit=off and a huge commit_delay to reduce fsync() costs. This won't help much if you've batched your work into big transactions, though.

• INSERT or COPY in parallel from several connections. How many depends on your hardware's disk subsystem; as a rule of thumb, you want one connection per physical hard drive if using direct attached storage.

• Set a high checkpoint_segments value and enable log_checkpoints. Look at the PostgreSQL logs and make sure it's not complaining about checkpoints occurring too frequently.

• If and only if you don't mind losing your entire PostgreSQL cluster (your database and any others on the same cluster) to catastrophic corruption if the system crashes during the import, you can stop Pg, set fsync=off, start Pg, do your import, then (vitally) stop Pg and set fsync=on again. See WAL configuration. Do not do this if there is already any data you care about in any database on your PostgreSQL install. If you set fsync=off you can also set full_page_writes=off; again, just remember to turn it back on after your import to prevent database corruption and data loss. See non-durable settings in the Pg manual.

You should also look at tuning your system:

• Use good quality SSDs for storage as much as possible. Good SSDs with reliable, power-protected write-back caches make commit rates incredibly faster. They're less beneficial when you follow the advice above - which reduces disk flushes / number of fsync()s - but can still be a big help. Do not use cheap SSDs without proper power-failure protection unless you don't care about keeping your data.

• If you're using RAID 5 or RAID 6 for direct attached storage, stop now. Back your data up, restructure your RAID array to RAID 10, and try again. RAID 5/6 are hopeless for bulk write performance - though a good RAID controller with a big cache can help.

• If you have the option of using a hardware RAID controller with a big battery-backed write-back cache this can really improve write performance for workloads with lots of commits. It doesn't help as much if you're using async commit with a commit_delay or if you're doing fewer big transactions during bulk loading.

• If possible, store WAL (pg_xlog) on a separate disk / disk array. There's little point in using a separate filesystem on the same disk. People often choose to use a RAID1 pair for WAL. Again, this has more effect on systems with high commit rates, and it has little effect if you're using an unlogged table as the data load target.

Even though you see the time in HH:MM AM/PM format, on the backend it still works in 24 hour format, you can try using some basic javascript to see that.

You can't have multiple time the same ID for elements. It is meant to be unique.

Use a class and make your IDs unique:

<div class="solTitle" id="solTitle1"> <a href = "#"  id = "solution0" onClick = "openSolution();">Solution0 </a></div>

And use the class selector:

$('.solTitle a').click(function(evt) {

    evt.preventDefault();
    alert('here in');
    var divId = 'summary' + this.id.substring(0, this.id.length-1);

    document.getElementById(divId).className = ''; 

});

I had the same problem with JDK6,I changed the JDK to JDK8,the problem solved. Try to use JDK8!!!

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

You also can do it with functional programming:

from functools import reduce
reduce(lambda df1, df2: df1.merge(df2, "outer"), mydfs)

jQuery dialog has an isOpen property that can be used to check if a jQuery dialog is open or not.

You can see example at this link: http://www.codegateway.com/2012/02/detect-if-jquery-dialog-box-is-open.html

You have to create a custom control by inheriting the textbox. Below link has an excellent example about the search textbox sample. Please have a look at this

http://davidowens.wordpress.com/2009/02/18/wpf-search-text-box/

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
    android:color="#ffffff"
    />
</shape>

Set that on your XML drawable resources, and simple use and image button with an round image, using your drawable as background.

Access-Control-Allow-Headers does not allow * as accepted value, see the Mozilla Documentation here.

Instead of the asterisk, you should send the accepted headers (first X-Requested-With as the error says).

That is because you are not fully qualifying your cells object. Try this

With Worksheets("SheetName")
    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

Notice the DOT before Cells?

A combination of list comprehensions and str joins can do the job:

inf = float('inf')
A = [[0,1,4,inf,3],
     [1,0,2,inf,4],
     [4,2,0,1,5],
     [inf,inf,1,0,3],
     [3,4,5,3,0]]

print('\n'.join([''.join(['{:4}'.format(item) for item in row]) 
      for row in A]))

yields

   0   1   4 inf   3
   1   0   2 inf   4
   4   2   0   1   5
 inf inf   1   0   3
   3   4   5   3   0

Using for-loops with indices is usually avoidable in Python, and is not considered "Pythonic" because it is less readable than its Pythonic cousin (see below). However, you could do this:

for i in range(n):
    for j in range(n):
        print '{:4}'.format(A[i][j]),
    print

The more Pythonic cousin would be:

for row in A:
    for val in row:
        print '{:4}'.format(val),
    print

However, this uses 30 print statements, whereas my original answer uses just one.

On Windows 7 just run the studio.bat file in your android-studio/bin folder with right click as an administrator. Now you get ask to import previous studio settings. Ignore this and on the next dialog you can specify the path to your jdk directory. That's all.

As an alternative to the important keyword, you could make the selector more specific, for example:

.left.background-none { background:none; }

(Note: no space between the class names).

In this case, the rule will apply when both .left and .background-none are listed in the class attribute (regardless of the order or proximity).

If you have used extern for functions before, exactly same philosophy is followed for templates. if not, going though extern for simple functions may help. Also, you may want to put the extern(s) in header file and include the header when you need it.

Try this:

diff -rq /path/to/folder1 /path/to/folder2      

Error message looks like this

Error message => ORA-00001: unique constraint (schema.unique_constraint_name) violated

ORA-00001 occurs when: "a query tries to insert a "duplicate" row in a table". It makes an unique constraint to fail, consequently query fails and row is NOT added to the table."

Solution:

Find all columns used in unique_constraint, for instance column a, column b, column c, column d collectively creates unique_constraint and then find the record from source data which is duplicate, using following queries:

-- to find <<owner of the table>> and <<name of the table>> for unique_constraint

select *
from DBA_CONSTRAINTS
where CONSTRAINT_NAME = '<unique_constraint_name>';

Then use Justin Cave's query (pasted below) to find all columns used in unique_constraint:

  SELECT column_name, position
  FROM all_cons_columns
  WHERE constraint_name = <<name of constraint from the error message>>
   AND owner           = <<owner of the table>>
   AND table_name      = <<name of the table>>

    -- to find duplicates

    select column a, column b, column c, column d
    from table
    group by column a, column b, column c, column d
    having count (<any one column used in constraint > ) > 1;

you can either delete that duplicate record from your source data (which was a select query in my particular case, as I experienced it with "Insert into select") or modify to make it unique or change the constraint.

While I tried the approach above, it becomes a complete disaster with mvc. Your controller passing a model and your view using a strongly typed model become too difficult to work with.

Get your Dataset into a List ..... I have a repository pattern and here is an example of getting a dataset from an old school asmx web service private readonly CISOnlineSRVDEV.ServiceSoapClient _ServiceSoapClient;

    public Get_Client_Repository()
        : this(new CISOnlineSRVDEV.ServiceSoapClient())
    {

    }
    public Get_Client_Repository(CISOnlineSRVDEV.ServiceSoapClient serviceSoapClient)
    {
        _ServiceSoapClient = serviceSoapClient;
    }


    public IEnumerable<IClient> GetClient(IClient client)
    {
        // ****  Calling teh web service with passing in the clientId and returning a dataset
        DataSet dataSet = _ServiceSoapClient.get_clients(client.RbhaId,
                                                        client.ClientId,
                                                        client.AhcccsId,
                                                        client.LastName,
                                                        client.FirstName,
                                                        "");//client.BirthDate.ToString());  //TODO: NEED TO FIX

        // USE LINQ to go through the dataset to make it easily available for the Model to display on the View page
        List<IClient> clients = (from c in dataSet.Tables[0].AsEnumerable()
                                 select new Client()
                                 {
                                     RbhaId = c[5].ToString(),
                                     ClientId = c[2].ToString(),
                                     AhcccsId = c[6].ToString(),
                                     LastName = c[0].ToString(), // Add another field called   Sex M/F  c[4]
                                     FirstName = c[1].ToString(),
                                     BirthDate = c[3].ToDateTime()  //extension helper  ToDateTime()
                                 }).ToList<IClient>();

        return clients;

    }

Then in the Controller I'm doing this

IClient client = (IClient)TempData["Client"];

// Instantiate and instance of the repository 
var repository = new Get_Client_Repository();
// Set a model object to return the dynamic list from repository method call passing in the parameter data
var model = repository.GetClient(client);

// Call the View up passing in the data from the list
return View(model);

Then in the View it is easy :

@model IEnumerable<CISOnlineMVC.DAL.IClient>

@{
    ViewBag.Title = "CLIENT ALL INFORMATION";
}

<h2>CLIENT ALL INFORMATION</h2>

<table>
    <tr>
        <th></th>
        <th>Last Name</th>
        <th>First Name</th>
        <th>Client ID</th>
        <th>DOB</th>
        <th>Gender</th>
        <th>RBHA ID</th>
        <th>AHCCCS ID</th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.ActionLink("Select", "ClientDetails", "Cis", new { id = item.ClientId }, null) |
        </td>
        <td>
            @item.LastName
        </td>
        <td>
            @item.FirstName
        </td>
         <td>
            @item.ClientId
        </td>
         <td>
            @item.BirthDate
        </td>
         <td>
            Gender @* ADD in*@
        </td>
         <td>
            @item.RbhaId
        </td>
         <td>
            @item.AhcccsId
        </td>
    </tr>
}

</table>

You need to use the scrollTop property.

document.getElementById('box').scrollTop

Set both DATE_FORMAT and USE_L10N

To make changes for the entire site in Django 1.4.1 add:

DATE_FORMAT = "Y-m-d"

to your settings.py file and edit:

USE_L10N = False

since l10n overrides DATE_FORMAT

This is documented at: https://docs.djangoproject.com/en/dev/ref/settings/#date-format

Use something like this (Not compiler checked)

NSMutableAttributedString *string = [[NSMutableAttributedString alloc]initWithString:self.text.text];
NSRange range=[self.myLabel.text rangeOfString:texts[sliderValue]]; //myLabel is the outlet from where you will get the text, it can be same or different

NSArray *colors=@[[UIColor redColor],
                  [UIColor redColor],
                  [UIColor yellowColor],
                  [UIColor greenColor]
                 ];

[string addAttribute:NSForegroundColorAttributeName 
               value:colors[sliderValue] 
               range:range];           

[self.scanLabel setAttributedText:texts[sliderValue]];

You can use the following

import { find } from 'lodash'

Then to return the entire object (not only its key or value) from the list with the following:

let match = find(savedViews, { 'ID': 'id to match'});

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

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

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

you can try below:

UIView *separator = [[UIView alloc] initWithFrame:CGRectMake(0, cell.contentView.frame.size.height - 1.0, cell.contentView.frame.size.width, 1)];
separator.backgroundColor = myColor;
[cell.contentView addSubview:separator];

or

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
   UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"separator.png"]];
   imageView.frame = CGRectMake(0, 100, 320, 1);
   [customCell.contentView addSubview:imageView];

   return customCell;
}

You could basically use html tags in your string resource like:

<resource>
    <string name="styled_welcome_message">We are <b><i>so</i></b> glad to see you.</string>
</resources>

And use Html.fromHtml or use spannable, check the link I posted.

Old similar question: Is it possible to have multiple styles inside a TextView?

Try the following idea:

var firstBornDate = People.GroupBy(p => p.DateOfBirth).Min(g => g.Key).FirstOrDefault();

For slow queries on version < 5.1, the following configuration worked for me:

log_slow_queries=/var/log/mysql/slow-query.log
long_query_time=20
log_queries_not_using_indexes=YES

Also note to place it under [mysqld] part of the config file and restart mysqld.

use the fully qualified name instead of importing the class.

e.g.

//import java.util.Date; //delete this
//import my.own.Date;

class Test{

   public static void main(String [] args){

      // I want to choose my.own.Date here. How?
      my.own.Date myDate = new my.own.Date();

      // I want to choose util.Date here. How ?
      java.util.Date javaDate = new java.util.Date();
   }
}

I found an answer now. Thanks for your suggestions!

for e in ./*.cutoff.txt; do

Any comments on that? It seems inefficient to grep twice, but it works...

this command works.

This answer is for docker-compose version 2 and it also works on version 3

You can still access the data when you use depends_on.

If you look at docker docs Docker Compose and Django, you still can access the database like this:

version: '2'
services:
  db:
    image: postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

What is the difference between links and depends_on?

links:

When you create a container for a database, for example:

docker run -d --name=test-mysql --env="MYSQL_ROOT_PASSWORD=mypassword" -P mysql

docker inspect d54cf8a0fb98 |grep HostPort

And you may find

"HostPort": "32777"

This means you can connect the database from your localhost port 32777 (3306 in container) but this port will change every time you restart or remove the container. So you can use links to make sure you will always connect to the database and don't have to know which port it is.

web:
  links:
   - db

depends_on:

I found a nice blog from Giorgio Ferraris Docker-compose.yml: from V1 to V2

When docker-compose executes V2 files, it will automatically build a network between all of the containers defined in the file, and every container will be immediately able to refer to the others just using the names defined in the docker-compose.yml file.

And

So we don’t need links anymore; links were used to start a network communication between our db container and our web-server container, but this is already done by docker-compose

Update

depends_on

Express dependency between services, which has two effects:

• docker-compose up will start services in dependency order. In the following example, db and redis will be started before web.
• docker-compose up SERVICE will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.

Simple example:

version: '2'
services:
  web:
    build: .
    depends_on:
      - db
      - redis
  redis:
    image: redis
  db:
    image: postgres

Note: depends_on will not wait for db and redis to be “ready” before starting web - only until they have been started. If you need to wait for a service to be ready, see Controlling startup order for more on this problem and strategies for solving it.

A simple solution is encapsulate code of button event in a function, and call it when you add TRs too:

 var i = 1;
$("#addbutton").click(function() {
  $("table tr:first").clone().find("input").each(function() {
    $(this).val('').attr({
      'id': function(_, id) {return id + i },
      'name': function(_, name) { return name + i },
      'value': ''               
    });
  }).end().appendTo("table");
  i++;

  applyRemoveEvent();  
});


function applyRemoveEvent(){
    $('button.removebutton').on('click',function() {
        alert("aa");
      $(this).closest( 'tr').remove();
      return false;
    });
};

applyRemoveEvent();

Within your onDropDownChange handler, just make a jQuery AJAX call, passing in any data you need to pass up to your URL. You can handle successful and failure calls with the success and error options. In the success option, use the data contained in the data argument to do whatever rendering you need to do. Remember these are asynchronous by default!

function onDropDownChange(e) {
    var url = '/Home/Index/' + e.value;
    $.ajax({
      url: url,
      data: {}, //parameters go here in object literal form
      type: 'GET',
      datatype: 'json',
      success: function(data) { alert('got here with data'); },
      error: function() { alert('something bad happened'); }
    });
}

jQuery's AJAX documentation is here.

1. you need to convert SVG to XML to use in android project.

1.1 you can do this with this site: http://inloop.github.io/svg2android/ but it does not support all the features of SVG like some gradients.

1.2 you can convert via android studio but it might use some features that only supports API 24 and higher that cuase crashe your app in older devices.

and add vectorDrawables.useSupportLibrary = true in gradle file and use like this:

<android.support.v7.widget.AppCompatImageView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:srcCompat="@drawable/ic_item1" />

2. use this library https://github.com/MegatronKing/SVG-Android that supports these features : https://github.com/MegatronKing/SVG-Android/blob/master/support_doc.md

add this code in application class:

public void onCreate() {
    SVGLoader.load(this)
}

and use the SVG like this :

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_android_red"/>

The ugly workaround would be to pass a boolean param to Papa indicating that you do not wish to parse the code contained in it's constructor. i.e:

// main class that everything inherits
class Grandpa 
{
    public function __construct()
    {

    }

}

class Papa extends Grandpa
{
    public function __construct($bypass = false)
    {
        // only perform actions inside if not bypassing
        if (!$bypass) {

        }
        // call Grandpa's constructor
        parent::__construct();
    }
}

class Kiddo extends Papa
{
    public function __construct()
    {
        $bypassPapa = true;
        parent::__construct($bypassPapa);
    }
}

For me,

Project ---> Source ---> Format

solved the problem

Simply, just replace , in your guideline tag

app:layout_constraintGuide_begin="291dp"

with

app:layout_constraintGuide_percent="0.7"

where 0.7 means 70%.

Also if you now try to drag guidelines, the dragged value will now show up in %age.

As an alternative you can also query the information_schema database and retrieve the data from the global_variables (and global_status of course too). This approach provides the same information, but gives you the opportunity to do more with the results, as it is a plain old query.

For example you can convert units to become more readable. The following query provides the current global setting for the innodb_log_buffer_size in bytes and megabytes:

SELECT
  variable_name,
  variable_value AS innodb_log_buffer_size_bytes,
  ROUND(variable_value / (1024*1024)) AS innodb_log_buffer_size_mb
FROM information_schema.global_variables
WHERE variable_name LIKE  'innodb_log_buffer_size';

As a result you get:

+------------------------+------------------------------+---------------------------+
| variable_name          | innodb_log_buffer_size_bytes | innodb_log_buffer_size_mb |
+------------------------+------------------------------+---------------------------+
| INNODB_LOG_BUFFER_SIZE | 268435456                    |                       256 |
+------------------------+------------------------------+---------------------------+

$ sbt sbtVersion

This prints the sbt version used in your current project, or if it is a multi-module project for each module.

$ sbt 'inspect sbtVersion'
[info] Set current project to jacek (in build file:/Users/jacek/)
[info] Setting: java.lang.String = 0.13.1
[info] Description:

You may also want to use sbt about that (copying Mark Harrah's comment):

The about command was added recently to try to succinctly print the most relevant information, including the sbt version.

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

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

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

I needed a UTC Timestamp as a default value and so modified Daniel's solution like this:

    [Column(TypeName = "datetime2")]
    [XmlAttribute]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
    [Display(Name = "Date Modified")]
    [DateRange(Min = "1900-01-01", Max = "2999-12-31")]
    public DateTime DateModified {
        get { return dateModified; }
        set { dateModified = value; } 
    }
    private DateTime dateModified = DateTime.Now.ToUniversalTime();

For DateRangeAttribute tutorial, see this awesome blog post

Another reason is that <u> tags are deprecated in XHTML and HTML5, so it would need to produce something like <span style="text-decoration:underline">this</span>. (IMHO, if <u> is deprecated, so should be <b> and <i>.) Note that Markdown produces <strong> and <em> instead of <b> and <i>, respectively, which explains the purpose of the text therein instead of its formatting. Formatting should be handled by stylesheets.

Update: The <u> element is no longer deprecated in HTML5.

Use UIAlertController instead of UIAlertView

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{
UIAlertController * alert=   [UIAlertController
                              alertControllerWithTitle:title
                              message:message
                              preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    //do something when click button
}];
[alert addAction:okAction];
UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
[vc presentViewController:alert animated:YES completion:nil];
}

foreach((array)$items as $item) {}

Don't forget to take into consideration the global flag in your regexp :

var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi');    // => true
reg.test('abcdefghi');    // => false <=

This is because Regexp keeps track of the lastIndex when a new match is found.

So I finally got it(http://jsfiddle.net/ncapito/eYtU5/):

.centerWrapper:before {
    content:'';
    height: 100%;
    display: inline-block;
    vertical-align: middle;
}

.center {
    display:inline-block;
    vertical-align: middle;
}

<div class='row'>
    <div class='login-icon'>
        <div class='centerWrapper'>
            <div class='center'> <i class='icon-user'></i></div>
       </div>
    </div>
    <input type="text" placeholder="Email" />
 </div>

std::list doesn't provide any function to get element given an index. You may try to get it by writing some code, which I wouldn't recommend, because that would be inefficient if you frequently need to do so.

What you need is : std::vector. Use it as:

std::vector<Object> objects;
objects.push_back(myObject);

Object const & x = objects[0];    //index isn't checked
Object const & y = objects.at(0); //index is checked 

Where the data returned is a string; you could cast to a different data type:

(from DataRow row in dataTable.Rows select row["columnName"].ToString()).ToList();

Consider the following simple Python script:

import time
import sys

for i in range(5):
    print(i),
    #sys.stdout.flush()
    time.sleep(1)

This is designed to print one number every second for five seconds, but if you run it as it is now (depending on your default system buffering) you may not see any output until the script completes, and then all at once you will see 0 1 2 3 4 printed to the screen.

This is because the output is being buffered, and unless you flush sys.stdout after each print you won't see the output immediately. Remove the comment from the sys.stdout.flush() line to see the difference.

If you're using Unity, you don't need to change this in Xcode, you can apply a compile flag in the metadata for the specific file(s), right inside Unity. Just select them in the Project panel, and apply from the Inspector panel. This is essential if you plan on using Cloud Build.

First Install React dev tools if not installed and then use the run below code in the browser console :

__REACT_DEVTOOLS_GLOBAL_HOOK__.renderers.get(1).version

Here is my approach to the problem:

Step 1 - Find the private key, ssh port and IP:

root@vivi:/opt/boxes/jessie# vagrant ssh-config
Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile /root/.vagrant.d/insecure_private_key
  IdentitiesOnly yes
  LogLevel FATAL

Step 2 - Transfer file using the port and private key as parameters for scp:

  scp -P 2222 -i /root/.vagrant.d/insecure_private_key \
  someFileName.txt [email protected]:~

I hope it helps,

Shorter version:

public static String unescapeJava(String escaped) {
    if(escaped.indexOf("\\u")==-1)
        return escaped;

    String processed="";

    int position=escaped.indexOf("\\u");
    while(position!=-1) {
        if(position!=0)
            processed+=escaped.substring(0,position);
        String token=escaped.substring(position+2,position+6);
        escaped=escaped.substring(position+6);
        processed+=(char)Integer.parseInt(token,16);
        position=escaped.indexOf("\\u");
    }
    processed+=escaped;

    return processed;
}

It just came up to me that maybe T attribute is a valid choice. Transpose, can get away from the somewhat misleading df.loc[-1] = [2, 3, 4] as @flow2k mentioned, and it is suitable for more universal situation such as you want to insert [2, 3, 4] before arbitrary row, which is hard for concat(),append() to achieve. And there's no need to bare the trouble defining and debugging a function.

a = df.T
a.insert(0,'anyName',value=[2,3,4])
# just give insert() any column name you want, we'll rename it.
a.rename(columns=dict(zip(a.columns,[i for i in range(a.shape[1])])),inplace=True)
# set inplace to a Boolean as you need.
df=a.T
df

    A   B   C
0   2   3   4
1   5   6   7
2   7   8   9

I guess this can partly explain @MattCochrane 's complaint about why pandas doesn't have a method to insert a row like insert() does.

this means your file is running now. just enter below code and try again:

sudo pkill node

Use the Control.ControlCollection.Find method.

Try this:

this.Controls.Find()

After some more research, it appears, for Mozilla/Firefox, that Array.sort() uses mergesort. See the code here.

Here are some easy to folow steps and a great on hover tutorial its the examples that you can "play" with and test live.

You can choose the url where the form must be posted (and thus, the invoked action) in different ways, depending on the browser support:

• for newer browsers that support HTML5, you can use formaction attribute of a submit button
• for older browsers that don't support this, you need to use some JavaScript that changes the form's action attribute, when the button is clicked, and before submitting

In this way you don't need to do anything special on the server side.

Of course, you can use Url extensions methods in your Razor to specify the form action.

For browsers supporting HMTL5: simply define your submit buttons like this:

<input type='submit' value='...' formaction='@Url.Action(...)' />

For older browsers I recommend using an unobtrusive script like this (include it in your "master layout"):

$(document).on('click', '[type="submit"][data-form-action]', function (event) {
  var $this = $(this);
  var formAction = $this.attr('data-form-action');
  $this.closest('form').attr('action', formAction);
});

NOTE: This script will handle the click for any element in the page that has type=submit and data-form-action attributes. When this happens, it takes the value of data-form-action attribute and set the containing form's action to the value of this attribute. As it's a delegated event, it will work even for HTML loaded using AJAX, without taking extra steps.

Then you simply have to add a data-form-action attribute with the desired action URL to your button, like this:

<input type='submit' data-form-action='@Url.Action(...)' value='...'/>

Note that clicking the button changes the form's action, and, right after that, the browser posts the form to the desired action.

As you can see, this requires no custom routing, you can use the standard Url extension methods, and you have nothing special to do in modern browsers.

You need to set$final[$id] to an array before adding elements to it. Intiialize it with either

$final[$id] = array();
$final[$id][0] = 3;
$final[$id]['link'] = "/".$row['permalink'];
$final[$id]['title'] = $row['title'];

or

$final[$id] = array(0 => 3);
$final[$id]['link'] = "/".$row['permalink'];
$final[$id]['title'] = $row['title'];

  <input attr1='a' attr2='b' attr3='c'>foo</input>

getAttribute(attr1) you get 'a'

getAttribute(attr2) you get 'b'

getAttribute(attr3) you get 'c'

getText() with no parameter you can only get 'foo'

This problem may be occur when there is problem in layout file. In my case I just use wrong way to call method

android:onClick="@={() -> viewModel.showText()}"

instead of

  android:onClick="@{() -> viewModel.showText()}"

From RFC 2616:

9.3 GET
The GET method means retrieve whatever information (in the form of an entity) is identified by the Request-URI. If the Request-URI refers to a data-producing process, it is the produced data which shall be returned as the entity in the response and not the source text of the process, unless that text happens to be the output of the process.

9.5 POST
The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. POST is designed to allow a uniform method to cover the following functions:

• Annotation of existing resources;
• Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;
• Providing a block of data, such as the result of submitting a form, to a data-handling process;
• Extending a database through an append operation.

The actual function performed by the POST method is determined by the server and is usually dependent on the Request-URI. The posted entity is subordinate to that URI in the same way that a file is subordinate to a directory containing it, a news article is subordinate to a newsgroup to which it is posted, or a record is subordinate to a database.

The action performed by the POST method might not result in a resource that can be identified by a URI. In this case, either 200 (OK) or 204 (No Content) is the appropriate response status, depending on whether or not the response includes an entity that describes the result.

Run apt-get install build-essential on your system.

This package depends on other packages considered to be essential for builds and will install them. If you find you have to build packages, this can be helpful to avoid piecemeal resolution of dependencies.

See this page for more info.

The "no version information available" means that the library version number is lower on the shared object. For example, if your major.minor.patch number is 7.15.5 on the machine where you build the binary, and the major.minor.patch number is 7.12.1 on the installation machine, ld will print the warning.

You can fix this by compiling with a library (headers and shared objects) that matches the shared object version shipped with your target OS. E.g., if you are going to install to RedHat 3.4.6-9 you don't want to compile on Debian 4.1.1-21. This is one of the reasons that most distributions ship for specific linux distro numbers.

Otherwise, you can statically link. However, you don't want to do this with something like PAM, so you want to actually install a development environment that matches your client's production environment (or at least install and link against the correct library versions.)

Advice you get to rename the .so files (padding them with version numbers,) stems from a time when shared object libraries did not use versioned symbols. So don't expect that playing with the .so.n.n.n naming scheme is going to help (much - it might help if you system has been trashed.)

You last option will be compiling with a library with a different minor version number, using a custom linking script: http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gnu-linker/scripts.html

To do this, you'll need to write a custom script, and you'll need a custom installer that runs ld against your client's shared objects, using the custom script. This requires that your client have gcc or ld on their production system.

In Xcode 12, you can change add as "appearances". This will work!!

I encountered this issue today. the issue has to do with the $config['base_url'] . I noticed htpp://www.domain.com and http://example.com was the issue. to fix , always set your base_url to http://www.example.com

Check out the range documentation, you have to define a negative step:

>>> range(10, 0, -1)
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

Another simple alternative:

<input ng-model="edItem" type="text" 
    ng-keypress="($event.which === 13)?foo(edItem):0"/>

And the ng-ui alternative:

<input ng-model="edItem" type="text" ui-keypress="{'enter':'foo(edItem)'}"/>

http://www.htmlgoodies.com/beyond/php/show-progress-report-for-long-running-php-scripts.html

I was searching for a similar solution and found this one use full.

var es;

function startTask() {
    es = new EventSource('yourphpfile.php');

//a message is received
es.addEventListener('message', function(e) {
    var result = JSON.parse( e.data );

    console.log(result.message);       

    if(e.lastEventId == 'CLOSE') {
        console.log('closed');
        es.close();
        var pBar = document.getElementById('progressor');
        pBar.value = pBar.max; //max out the progress bar
    }
    else {

        console.log(response); //your progress bar action
    }
});

es.addEventListener('error', function(e) {
    console.log('error');
    es.close();
});

}

and your server outputs

header('Content-Type: text/event-stream');
// recommended to prevent caching of event data.
header('Cache-Control: no-cache'); 

function send_message($id, $message, $progress) {
    $d = array('message' => $message , 'progress' => $progress); //prepare json

    echo "id: $id" . PHP_EOL;
    echo "data: " . json_encode($d) . PHP_EOL;
    echo PHP_EOL;

   ob_flush();
   flush();
}


//LONG RUNNING TASK
 for($i = 1; $i <= 10; $i++) {
    send_message($i, 'on iteration ' . $i . ' of 10' , $i*10); 

    sleep(1);
 }

send_message('CLOSE', 'Process complete');

You can change the decimal separator by changing the culture used to display the number. Beware however that this will change everything else about the number (eg. grouping separator, grouping sizes, number of decimal places). From your question, it looks like you are defaulting to a culture that uses a comma as a decimal separator.

To change just the decimal separator without changing the culture, you can modify the NumberDecimalSeparator property of the current culture's NumberFormatInfo.

Thread.CurrentCulture.NumberFormat.NumberDecimalSeparator = ".";

This will modify the current culture of the thread. All output will now be altered, meaning that you can just use value.ToString() to output the format you want, without worrying about changing the culture each time you output a number.

_{(Note that a neutral culture cannot have its decimal separator changed.)}

Use Console.SetOut to redirect to a TextWriter as described here: http://msdn.microsoft.com/en-us/library/system.console.setout.aspx

You use:

yourcommand  > /dev/null 2>&1

If it should run in the Background add an &

yourcommand > /dev/null 2>&1 &

>/dev/null 2>&1 means redirect stdout to /dev/null AND stderr to the place where stdout points at that time

If you want stderr to occur on console and only stdout going to /dev/null you can use:

yourcommand 2>&1 > /dev/null

In this case stderr is redirected to stdout (e.g. your console) and afterwards the original stdout is redirected to /dev/null

If the program should not terminate you can use:

nohup yourcommand &

Without any parameter all output lands in nohup.out

Edit: EF Core 2.1 finally supports GroupBy

But always look out in the console / log for messages. If you see a notification that your query could not be converted to SQL and will be evaluated locally then you may need to rewrite it.

Entity Framework 7 (now renamed to Entity Framework Core 1.0 / 2.0) does not yet support GroupBy() for translation to GROUP BY in generated SQL (even in the final 1.0 release it won't). Any grouping logic will run on the client side, which could cause a lot of data to be loaded.

Eventually code written like this will automagically start using GROUP BY, but for now you need to be very cautious if loading your whole un-grouped dataset into memory will cause performance issues.

For scenarios where this is a deal-breaker you will have to write the SQL by hand and execute it through EF.

If in doubt fire up Sql Profiler and see what is generated - which you should probably be doing anyway.

• fill_parent will make the width or height of the element to be as large as the parent element, in other words, the container.

• wrap_content will make the width or height be as large as needed to contain the elements within it.

^{_{Note: there is no guarantee this code will work in future versions of the .Net framework. Using private .Net framework internals as done here through reflection is probably not good overall. Use the interop solution mentioned at the bottom, as the Windows API is less likely to change.}}

If you are looking for a Folder picker that looks more like the Windows 7 dialog, with the ability to copy and paste from a textbox at the bottom and the navigation pane on the left with favorites and common locations, then you can get access to that in a very lightweight way.

The FolderBrowserDialog UI is very minimal:

But you can have this instead:

Here's a class that opens a Vista-style folder picker using the .Net private IFileDialog interface, without directly using interop in the code (.Net takes care of that for you). It falls back to the pre-Vista dialog if not in a high enough Windows version. Should work in Windows 7, 8, 9, 10 and higher (theoretically).

I developed this as a cleaned up version of .NET Win 7-style folder select dialog by Bill Seddon of lyquidity.com (I have no affiliation). I wrote my own because his solution requires an additional Reflection class that isn't needed for this focused purpose, uses exception-based flow control, doesn't cache the results of its reflection calls. Note that the nested static VistaDialog class is so that its static reflection variables don't try to get populated if the Show method is never called.

It is used like so in a Windows Form:

var dialog = new FolderSelectDialog {
    InitialDirectory = musicFolderTextBox.Text,
    Title = "Select a folder to import music from"
};
if (dialog.Show(Handle)) {
    musicFolderTextBox.Text = dialog.FileName;
}

You can of course play around with its options and what properties it exposes. For example, it allows multiselect in the Vista-style dialog.

Also, please note that Simon Mourier gave an answer that shows how to do the exact same job using interop against the Windows API directly, though his version would have to be supplemented to use the older style dialog if in an older version of Windows. Unfortunately, I hadn't found his post yet when I worked up my solution. Name your poison!

There is some problem for Tapas Bose code and Thomas code. If time differen?e is negative, array gets the negative values. For example if

LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 10, 6, 46, 45);
LocalDateTime fromDateTime = LocalDateTime.of(2014, 9, 9, 7, 46, 45);

it returns 0 years 0 months 1 days -1 hours 0 minutes 0 seconds.

I think the right output is: 0 years 0 months 0 days 23 hours 0 minutes 0 seconds.

I propose to separate the LocalDateTime instances on LocalDate and LocalTime instances. After that we can obtain the Java 8 Period and Duration instances. The Duration instance is separated on the number of days and throughout-the-day time value (< 24h) with subsequent correction of the period value. When the second LocalTime value is before the firstLocalTime value, it is necessary to reduce the period for one day.

Here's my way to calculate the LocalDateTime difference:

private void getChronoUnitForSecondAfterFirst(LocalDateTime firstLocalDateTime, LocalDateTime secondLocalDateTime, long[] chronoUnits) {
    /*Separate LocaldateTime on LocalDate and LocalTime*/
    LocalDate firstLocalDate = firstLocalDateTime.toLocalDate();
    LocalTime firstLocalTime = firstLocalDateTime.toLocalTime();

    LocalDate secondLocalDate = secondLocalDateTime.toLocalDate();
    LocalTime secondLocalTime = secondLocalDateTime.toLocalTime();

    /*Calculate the time difference*/
    Duration duration = Duration.between(firstLocalDateTime, secondLocalDateTime);
    long durationDays = duration.toDays();
    Duration throughoutTheDayDuration = duration.minusDays(durationDays);
    Logger.getLogger(PeriodDuration.class.getName()).log(Level.INFO,
            "Duration is: " + duration + " this is " + durationDays
            + " days and " + throughoutTheDayDuration + " time.");

    Period period = Period.between(firstLocalDate, secondLocalDate);

    /*Correct the date difference*/
    if (secondLocalTime.isBefore(firstLocalTime)) {
        period = period.minusDays(1);
        Logger.getLogger(PeriodDuration.class.getName()).log(Level.INFO,
                "minus 1 day");
    }

    Logger.getLogger(PeriodDuration.class.getName()).log(Level.INFO,
            "Period between " + firstLocalDateTime + " and "
            + secondLocalDateTime + " is: " + period + " and duration is: "
            + throughoutTheDayDuration
            + "\n-----------------------------------------------------------------");

    /*Calculate chrono unit values and  write it in array*/
    chronoUnits[0] = period.getYears();
    chronoUnits[1] = period.getMonths();
    chronoUnits[2] = period.getDays();
    chronoUnits[3] = throughoutTheDayDuration.toHours();
    chronoUnits[4] = throughoutTheDayDuration.toMinutes() % 60;
    chronoUnits[5] = throughoutTheDayDuration.getSeconds() % 60;
}

The above method can be used to calculate the difference of any local date and time values, for example:

public long[] getChronoUnits(String firstLocalDateTimeString, String secondLocalDateTimeString) {
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

    LocalDateTime firstLocalDateTime = LocalDateTime.parse(firstLocalDateTimeString, formatter);
    LocalDateTime secondLocalDateTime = LocalDateTime.parse(secondLocalDateTimeString, formatter);

    long[] chronoUnits = new long[6];
    if (secondLocalDateTime.isAfter(firstLocalDateTime)) {
        getChronoUnitForSecondAfterFirst(firstLocalDateTime, secondLocalDateTime, chronoUnits);
    } else {
        getChronoUnitForSecondAfterFirst(secondLocalDateTime, firstLocalDateTime, chronoUnits);
    }
    return chronoUnits;
}

It is convenient to write a unit test for the above method (both of them are PeriodDuration class members). Here's the code:

@RunWith(Parameterized.class)
public class PeriodDurationTest {

private final String firstLocalDateTimeString;
private final String secondLocalDateTimeString;
private final long[] chronoUnits;

public PeriodDurationTest(String firstLocalDateTimeString, String secondLocalDateTimeString, long[] chronoUnits) {
    this.firstLocalDateTimeString = firstLocalDateTimeString;
    this.secondLocalDateTimeString = secondLocalDateTimeString;
    this.chronoUnits = chronoUnits;
}

@Parameters
public static Collection<Object[]> periodValues() {
    long[] chronoUnits0 = {0, 0, 0, 0, 0, 0};
    long[] chronoUnits1 = {0, 0, 0, 1, 0, 0};
    long[] chronoUnits2 = {0, 0, 0, 23, 0, 0};
    long[] chronoUnits3 = {0, 0, 0, 1, 0, 0};
    long[] chronoUnits4 = {0, 0, 0, 23, 0, 0};
    long[] chronoUnits5 = {0, 0, 1, 23, 0, 0};
    long[] chronoUnits6 = {29, 8, 24, 12, 0, 50};
    long[] chronoUnits7 = {29, 8, 24, 12, 0, 50};
    return Arrays.asList(new Object[][]{
        {"2015-09-09 21:46:44", "2015-09-09 21:46:44", chronoUnits0},
        {"2015-09-09 21:46:44", "2015-09-09 22:46:44", chronoUnits1},
        {"2015-09-09 21:46:44", "2015-09-10 20:46:44", chronoUnits2},
        {"2015-09-09 21:46:44", "2015-09-09 20:46:44", chronoUnits3},
        {"2015-09-10 20:46:44", "2015-09-09 21:46:44", chronoUnits4},
        {"2015-09-11 20:46:44", "2015-09-09 21:46:44", chronoUnits5},
        {"1984-12-16 07:45:55", "2014-09-09 19:46:45", chronoUnits6},
        {"2014-09-09 19:46:45", "1984-12-16 07:45:55", chronoUnits6}
    });
}

@Test
public void testGetChronoUnits() {
    PeriodDuration instance = new PeriodDuration();
    long[] expResult = this.chronoUnits;
    long[] result = instance.getChronoUnits(this.firstLocalDateTimeString, this.secondLocalDateTimeString);
    assertArrayEquals(expResult, result);
}

}

All tests are successful whether or not the value of the first LocalDateTime is before and for any LocalTime values.

Here is a simple demo to create customview (compoundview) by inflating from xml

attrs.xml

<resources>

    <declare-styleable name="CustomView">
        <attr format="string" name="text"/>
        <attr format="reference" name="image"/>
    </declare-styleable>
</resources>

CustomView.kt

class CustomView @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) :
        ConstraintLayout(context, attrs, defStyleAttr) {

    init {
        init(attrs)
    }

    private fun init(attrs: AttributeSet?) {
        View.inflate(context, R.layout.custom_layout, this)

        val ta = context.obtainStyledAttributes(attrs, R.styleable.CustomView)
        try {
            val text = ta.getString(R.styleable.CustomView_text)
            val drawableId = ta.getResourceId(R.styleable.CustomView_image, 0)
            if (drawableId != 0) {
                val drawable = AppCompatResources.getDrawable(context, drawableId)
                image_thumb.setImageDrawable(drawable)
            }
            text_title.text = text
        } finally {
            ta.recycle()
        }
    }
}

custom_layout.xml

We should use merge here instead of ConstraintLayout because

If we use ConstraintLayout here, layout hierarchy will be ConstraintLayout->ConstraintLayout -> ImageView + TextView => we have 1 redundant ConstraintLayout => not very good for performance

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:parentTag="android.support.constraint.ConstraintLayout">

    <ImageView
        android:id="@+id/image_thumb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        tools:ignore="ContentDescription"
        tools:src="@mipmap/ic_launcher" />

    <TextView
        android:id="@+id/text_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="@id/image_thumb"
        app:layout_constraintStart_toStartOf="@id/image_thumb"
        app:layout_constraintTop_toBottomOf="@id/image_thumb"
        tools:text="Text" />

</merge>

Using activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <your_package.CustomView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#f00"
        app:image="@drawable/ic_android"
        app:text="Android" />

    <your_package.CustomView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#0f0"
        app:image="@drawable/ic_adb"
        app:text="ADB" />

</LinearLayout>

For those who wants to type password within the command line. It is possible but recommend to pass it inside quotes so that the special character won't cause any issue.

mysqldump -h'my.address.amazonaws.com' -u'my_username' -p'password' db_name > /path/backupname.sql

If you got node __dirname not defined with node --experimental-modules, you can do :

const __dirname = path.dirname(import.meta.url)
                      .replace(/^file:\/\/\//, '') // can be usefull

Because othe example, work only with current/pwd directory not other directory.

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

In SQL Server 2017 STRING_AGG is added:

SELECT t.name,STRING_AGG (c.name, ',') AS csv
FROM sys.tables t
JOIN sys.columns c on t.object_id = c.object_id
GROUP BY t.name
ORDER BY 1

Also, STRING_SPLIT is usefull for the opposite case and available in SQL Server 2016

Actually, just before FF3 was out, I did some experiments, and FF2 sends only the filename, like did Opera 9.0. Only IE sends the full path. The behavior makes sense, because the server doesn't have to know where the user stores the file on his computer, it is irrelevant to the upload process. Unless you are writing an intranet application and get the file by direct network access!

What have changed (and that's the real point of the bug item you point to) is that FF3 no longer let access to the file path from JavaScript. And won't let type/paste a path there, which is more annoying for me: I have a shell extension which copies the path of a file from Windows Explorer to the clipboard and I used it a lot in such form. I solved the issue by using the DragDropUpload extension. But this becomes off-topic, I fear.

I wonder what your Web forms are doing to stop working with this new behavior.

[EDIT] After reading the page linked by Mike, I see indeed intranet uses of the path (identify a user for example) and local uses (show preview of an image, local management of files). User Jam-es seems to provide a workaround with nsIDOMFile (not tried yet).

You can get this error if you use wrong mode when opening the file. For example:

    with open(output, 'wb') as output_file:
        print output_file.read()

In that code, I want to read the file, but I use mode wb instead of r or r+

Not really. See File input 'accept' attribute - is it useful? .

Use std::cout, since cout is defined within the std namespace. Alternatively, add a using std::cout; directive.

Little sum up for searching by row:

This can be useful if you don't know the column values ??or if columns have non-numeric values

if u want get index number as integer u can also do:

item = df[4:5].index.item()
print(item)
4

it also works in numpy / list:

numpy = df[4:7].index.to_numpy()[0]
lista = df[4:7].index.to_list()[0]

in [x] u pick number in range [4:7], for example if u want 6:

numpy = df[4:7].index.to_numpy()[2]
print(numpy)
6

for DataFrame:

df[4:7]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449

or:

df[(df.index>=4) & (df.index<7)]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449   

1. Add an exit handler that closes all the bars.
2. __del__() gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.
3. If __init__() raises an exception then the object is assumed to be incomplete and __del__() won't be invoked.

Basically <key>ITSAppUsesNonExemptEncryption</key><false/> stands for a Boolean value equal to NO.

Update by @JosepH: This value means that the app uses no encryption, or only exempt encryption. If your app uses encryption and is not exempt, you must set this value to YES/true.

It seems debatable sometimes when an app is considered to use encryption.

May be You are not registering the Controllers. Try below code:

Step 1. Write your own controller factory class ControllerFactory :DefaultControllerFactory by implementing defaultcontrollerfactory in models folder

  public class ControllerFactory :DefaultControllerFactory
    {
    protected override IController GetControllerInstance(RequestContext         requestContext, Type controllerType)
        {
            try
            {
                if (controllerType == null)
                    throw new ArgumentNullException("controllerType");

                if (!typeof(IController).IsAssignableFrom(controllerType))
                    throw new ArgumentException(string.Format(
                        "Type requested is not a controller: {0}",
                        controllerType.Name),
                        "controllerType");

                return MvcUnityContainer.Container.Resolve(controllerType) as IController;
            }
            catch
            {
                return null;
            }

        }
        public static class MvcUnityContainer
        {
            public static UnityContainer Container { get; set; }
        }
    }

Step 2:Regigster it in BootStrap: inBuildUnityContainer method

private static IUnityContainer BuildUnityContainer()
    {
      var container = new UnityContainer();

      // register all your components with the container here
      // it is NOT necessary to register your controllers

      // e.g. container.RegisterType<ITestService, TestService>();    
      //RegisterTypes(container);
      container = new UnityContainer();
      container.RegisterType<IProductRepository, ProductRepository>();


      MvcUnityContainer.Container = container;
      return container;
    }

Step 3: In Global Asax.

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            AuthConfig.RegisterAuth();
            Bootstrapper.Initialise();
            ControllerBuilder.Current.SetControllerFactory(typeof(ControllerFactory));

        }

And you are done

Make sure it's within a document ready tagAlternatively, try using .live

$(document).ready(function(){

    $('#content').live('click', function(e) {  
        alert(1);
    });
});

Example:

$(document).ready(function() {_x000D_
    $('#content').click(function(e) {  _x000D_
      alert(1);_x000D_
    });_x000D_
});

#content {_x000D_
    padding: 20px;_x000D_
    background: blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>_x000D_
<div id="content">Hello world</div>

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers.

$('#content').on( "click", function() {
    alert(1);
});

I had the same problem. I installed Eclipse 3.7 into a new folder, and created a new workspace. I launch Eclipse with a -data argument to reference the new workspace.

When I attempt to connect to the marketplace to get the SVN and Maven plugins, I get the same issues described in OP.

After a few more tries, I cleared the proxy settings for SOCKS protocol, and I was able to connect to the marketplace.

So the solution for me was to configure the manual settings for HTTP and HTTPS proxy, clear the settings for SOCKS, and restart Eclipse.

Line numbers are printed with grep -n:

grep -n pattern file.txt

To get only the line number (without the matching line), one may use cut:

grep -n pattern file.txt | cut -d : -f 1

Lines not containing a pattern are printed with grep -v:

grep -v pattern file.txt

If you want to disable this warning it is important to know that there are two related warning parameters in GCC and Clang: GCC Compiler options -wno-four-char-constants and -wno-multichar

Beginners needs practical examples. so try the following code.

public class Not_a_Number {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    String message = "0.0/0.0 is NaN.\nsimilarly Math.sqrt(-1) is NaN.";        
    String dottedLine = "------------------------------------------------";     

    Double numerator = -2.0;
    Double denominator = -2.0;      
    while (denominator <= 1) {
        Double x = numerator/denominator;           
        Double y = new Double (x);
        boolean z = y.isNaN();
        System.out.println("y =  " + y);
        System.out.println("z =  " + z);
        if (z == true){
            System.out.println(message);                
        }
        else {
            System.out.println("Hi, everyone"); 
        }
        numerator = numerator + 1;
        denominator = denominator +1;
        System.out.println(dottedLine);         
    } // end of while

} // end of main

} // end of class

HTTPS has encryption/decryption overhead so it will always be slightly slower. SSL termination is very CPU intensive. If you have devices to offload SSL, the difference in latencies might be barely noticeable depending on the load your servers are under.

Use open(fn, 'rb').read().decode('utf-8') instead of just open(fn).read()

Pretty much. One small difference though: if the Task fails, GetResult() will just throw the exception caused directly, while Task.Result will throw an AggregateException. However, what's the point of using either of those when it's async? The 100x better option is to use await.

Also, you're not meant to use GetResult(). It's meant to be for compiler use only, not for you. But if you don't want the annoying AggregateException, use it.

This will work:

WebElement searchbox = driver.findElement(By.name("j_username"));
WebElement searchbox2 = driver.findElement(By.name("j_password"));         


try {

      FileInputStream file = new FileInputStream(new File("C:\\paulo.xls")); 
      HSSFWorkbook workbook = new HSSFWorkbook(file);

      HSSFSheet sheet = workbook.getSheetAt(0);

    for (int i=1; i <= sheet.getLastRowNum(); i++){

            HSSFCell j_username = sheet.getRow(i).getCell(0)
            HSSFCell j_password = sheet.getRow(i).getCell(0)

            //Setting the Cell type as String
            j_username.setCellType(j_username.CELL_TYPE_STRING)
            j_password.setCellType(j_password.CELL_TYPE_STRING)

            searchbox.sendKeys(j_username.toString());
            searchbox2.sendKeys(j_password.toString());


            searchbox.submit();       

            driver.manage().timeouts().implicitlyWait(10000, TimeUnit.MILLISECONDS);

    }

      workbook.close();
      file.close();

     } catch (FileNotFoundException fnfe) {
      fnfe.printStackTrace();
     } catch (IOException ioe) {
      ioe.printStackTrace();
     }

public View recentView;

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //Create a relative layout and add a button
        relativeLayout = new RelativeLayout(this);
        btn = new Button(this);
        btn.setId((int)System.currentTimeMillis());
        recentView = btn;
        btn.setText("Click me");
        relativeLayout.addView(btn);


        setContentView(relativeLayout);

        btn.setOnClickListener(new View.OnClickListener() {

            @Overr ide
            public void onClick(View view) {

                //Create a textView, set a random ID and position it below the most recently added view
                textView = new TextView(ActivityName.this);
                textView.setId((int)System.currentTimeMillis());
                layoutParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
                layoutParams.addRule(RelativeLayout.BELOW, recentView.getId());
                textView.setText("Time: "+System.currentTimeMillis());
                relativeLayout.addView(textView, layoutParams);
                recentView = textView;
            }
        });
    }

This can be modified to display each element of a String array in different TextViews.

IMHO it is cpu and RAM dependant. On my Wolfdale (with Intel virtualisation technology) + 4GB of RAM it's very fast and usable. As I know the emu is qemu based so it`s better to have Intel with virtualisation tech enabled and don't forget to insert any virulatisation modules to the kernel (if using linux).

You can simply write like this

import java.net.InetAddress;
import java.net.UnknownHostException;

public class Main {

    private static final String HOST = "localhost";

    public static void main(String[] args) throws UnknownHostException {

        boolean isConnected = !HOST.equals(InetAddress.getLocalHost().getHostAddress().toString());

        if (isConnected) System.out.println("Connected");
        else System.out.println("Not connected");

    }
}

If it's an input element you can write something like.... <input type="radio" [checked]="condition"> The value of condition must be true or false.

Also for style attributes... <h4 [style.color]="'red'">Some text</h4>

Workaround for WebKit:

/* Disable tap highlighting */
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);

I found it in a CardFlip example.

Though you've already implemented it by now,

you can also use any expect implementation (you'll find alternatives in Perl, Python: pexpect, paramiko, etc..)

This is a pure javascript i am not using jQuery but works in all browser even IE and it is verry simple to understand

   <div id="my_div">
    <p>Paragraph one</p>
    <p>Paragraph two</p>
    <p>Paragraph three</p>
   </div>
   <button id ="my_button>Remove nodes ?</button>

   document.getElementById("my_button").addEventListener("click",function(){

  let parent_node =document.getElemetById("my_div"); //Div which contains paagraphs

  //Let find numbers of child inside the div then remove all
  for(var i =0; i < parent_node.childNodes.length; i++) {
     //To avoid a problem which may happen if there is no childNodes[i] 
     try{
       if(parent_node.childNodes[i]){
         parent_node.removeChild(parent_node.childNodes[i]);
       }
     }catch(e){
     }
  }

})

or you may simpli do this which is a quick way to do

document.getElementById("my_button").addEventListener("click",function(){

 let parent_node =document.getElemetById("my_div");
 parent_node.innerHTML ="";

})

Determining your Node version

node -v  // or node --version
npm -v   // npm version or long npm --version

Ensure that you have n installed

sudo npm install -g n // -g for global installation 

Upgrading to the latest stable version

sudo n stable

Changing to a specific version

sudo n 10.16.0

This webpage may be useful and time-saving when working with .gitignore.

It automatically generates .gitignore files for different IDEs and operating systems with the specific files/folders that you usually don't want to pull to your Git repository (for instance, IDE-specific folders and configuration files).

  from __future__ import print_function
import csv
import MySQLdb

print("Enter  File  To Be Export")
conn = MySQLdb.connect(host="localhost", port=3306, user="root", passwd="", db="database")
cursor = conn.cursor()
#sql = 'CREATE DATABASE test1'
sql ='''DROP TABLE IF EXISTS `test1`; CREATE TABLE test1 (policyID int, statecode varchar(255), county varchar(255))'''
cursor.execute(sql)

with open('C:/Users/Desktop/Code/python/sample.csv') as csvfile:
    reader = csv.DictReader(csvfile, delimiter = ',')
    for row in reader:
        print(row['policyID'], row['statecode'], row['county'])
        # insert
        conn = MySQLdb.connect(host="localhost", port=3306, user="root", passwd="", db="database")
        sql_statement = "INSERT INTO test1(policyID ,statecode,county) VALUES (%s,%s,%s)"
        cur = conn.cursor()
        cur.executemany(sql_statement,[(row['policyID'], row['statecode'], row['county'])])
        conn.escape_string(sql_statement)
        conn.commit()

I just use whatever strikes my fancy at the time; it's convenient to be able to switch between the two at a whim!

Of course, when quoting quote characetrs, switching between the two might not be so whimsical after all...

Go to xampp/php/php.ini

Find this line:

max_execution_time=30

And change its value to any number you want. Restart Apache.

Assuming the string is called myStr:

// Strip start and end quotation mark and possible initial comma
myStr=myStr.replace(/^,?'/,'').replace(/'$/,'');

// Split stripping quotations
myArray=myStr.split("','");

Note that if a string can be missing in the list without even having its quotation marks present and you want an empty spot in the corresponding location in the array, you'll need to write the splitting manually for a robust solution.

There are two options I'm aware of.

One, change the PYTHONPATH environment variable to include the directory above your module.

Alternatively, edit ~/.pylintrc to include the directory above your module, like this:

[MASTER]
init-hook='import sys; sys.path.append("/path/to/root")'

(Or in other version of pylint, the init-hook requires you to change [General] to [MASTER])

Both of these options ought to work.

Hope that helps.

Be aware that passing an Object with named properties as Ken suggested adds the cost of allocating and releasing the temporary object to every call. Passing normal arguments by value or reference will generally be the most efficient. For many applications though the performance is not critical but for some it can be.

You can't modify strings; they're immutable. You can do this instead:

txtBox.Text = txtBox.Text.Substring(0, i) + "TEXT" + txtBox.Text.Substring(i);
