1. Go to your computer's Recycle Bin.
2. Search for the specific file that got deleted.
3. Right click on that file. Go to Restore in the drop-down list.

Voila! The file is restored and is back in your folder. Happy Coding!

I know I'm a little late to the party, but I thought I might contribute my subjectively more graceful solution.

I was looking for a script that would empty the Recycle Bin with an API call, rather than crudely deleting all files and folders from the filesystem. Having failed in my attempts to RecycleBinObject.InvokeVerb("Empty Recycle &Bin") (which apparently only works in XP or older), I stumbled upon discussions of using a function embedded in shell32.dll called SHEmptyRecycleBin() from a compiled language. I thought, hey, I can do that in PowerShell and wrap it in a batch script hybrid.

Save this with a .bat extension and run it to empty your Recycle Bin. Run it with a /y switch to skip the confirmation.

<# : batch portion (begins PowerShell multi-line comment block)
:: empty.bat -- http://stackoverflow.com/a/41195176/1683264

@echo off & setlocal

if /i "%~1"=="/y" goto empty

choice /n /m "Are you sure you want to empty the Recycle Bin? [y/n] "
if not errorlevel 2 goto empty
goto :EOF

:empty
powershell -noprofile "iex (${%~f0} | out-string)" && (
    echo Recycle Bin successfully emptied.
)
goto :EOF

: end batch / begin PowerShell chimera #>
Add-Type shell32 @'
    [DllImport("shell32.dll")]
    public static extern int SHEmptyRecycleBin(IntPtr hwnd, string pszRootPath,
        int dwFlags);
'@ -Namespace System

$SHERB_NOCONFIRMATION = 0x1
$SHERB_NOPROGRESSUI = 0x2
$SHERB_NOSOUND = 0x4

$dwFlags = $SHERB_NOCONFIRMATION
$res = [shell32]::SHEmptyRecycleBin([IntPtr]::Zero, $null, $dwFlags)

if ($res) { "Error 0x{0:x8}: {1}" -f $res,`
    (New-Object ComponentModel.Win32Exception($res)).Message }
exit $res

Here's a more complex version which first invokes SHQueryRecycleBin() to determine whether the bin is already empty prior to invoking SHEmptyRecycleBin(). For this one, I got rid of the choice confirmation and /y switch.

import pandas as pd
import numpy as np

df = pd.DataFrame({'ItemQty': {0: 3, 1: 25}, 
                   'Seatblocks': {0: '2:218:10:4,6', 1: '1:13:36:1,12 1:13:37:1,13'}, 
                   'ItemExt': {0: 60, 1: 300}, 
                   'CustomerName': {0: 'McCartney, Paul', 1: 'Lennon, John'}, 
                   'CustNum': {0: 32363, 1: 31316}, 
                   'Item': {0: 'F04', 1: 'F01'}}, 
                    columns=['CustNum','CustomerName','ItemQty','Item','Seatblocks','ItemExt'])

print (df)
   CustNum     CustomerName  ItemQty Item                 Seatblocks  ItemExt
0    32363  McCartney, Paul        3  F04               2:218:10:4,6       60

Another similar solution with chaining is use reset_index and rename:

print (df.drop('Seatblocks', axis=1)
             .join
             (
             df.Seatblocks
             .str
             .split(expand=True)
             .stack()
             .reset_index(drop=True, level=1)
             .rename('Seatblocks')           
             ))

   CustNum     CustomerName  ItemQty Item  ItemExt    Seatblocks
0    32363  McCartney, Paul        3  F04       60  2:218:10:4,6
1    31316     Lennon, John       25  F01      300  1:13:36:1,12
1    31316     Lennon, John       25  F01      300  1:13:37:1,13

If in column are NOT NaN values, the fastest solution is use list comprehension with DataFrame constructor:

df = pd.DataFrame(['a b c']*100000, columns=['col'])

In [141]: %timeit (pd.DataFrame(dict(zip(range(3), [df['col'].apply(lambda x : x.split(' ')[i]) for i in range(3)]))))
1 loop, best of 3: 211 ms per loop

In [142]: %timeit (pd.DataFrame(df.col.str.split().tolist()))
10 loops, best of 3: 87.8 ms per loop

In [143]: %timeit (pd.DataFrame(list(df.col.str.split())))
10 loops, best of 3: 86.1 ms per loop

In [144]: %timeit (df.col.str.split(expand=True))
10 loops, best of 3: 156 ms per loop

In [145]: %timeit (pd.DataFrame([ x.split() for x in df['col'].tolist()]))
10 loops, best of 3: 54.1 ms per loop

But if column contains NaN only works str.split with parameter expand=True which return DataFrame (documentation), and it explain why it is slowier:

df = pd.DataFrame(['a b c']*10, columns=['col'])
df.loc[0] = np.nan
print (df.head())
     col
0    NaN
1  a b c
2  a b c
3  a b c
4  a b c

print (df.col.str.split(expand=True))
     0     1     2
0  NaN  None  None
1    a     b     c
2    a     b     c
3    a     b     c
4    a     b     c
5    a     b     c
6    a     b     c
7    a     b     c
8    a     b     c
9    a     b     c

Trivial solution with expressions. Note that with NewArrayInit you can create just one-dimensional array.

NewArrayExpression expr = Expression.NewArrayInit(typeof(int), new[] { Expression.Constant(2), Expression.Constant(3) });
int[] array = Expression.Lambda<Func<int[]>>(expr).Compile()(); // compile and call callback

String.Format adds many options in addition to the concatenation operators, including the ability to specify the specific format of each item added into the string.

For details on what is possible, I'd recommend reading the section on MSDN titled Composite Formatting. It explains the advantage of String.Format (as well as xxx.WriteLine and other methods that support composite formatting) over normal concatenation operators.

Unless you write your own Homescreen launcher or use an existing one from Goolge Play, there's "no way" to resize icons.

Well, "no way" does not mean its impossible:

• As said, you can write your own launcher as discussed in Stackoverflow.
• You can resize elements on the home screen, but these elements are AppWidgets. Since API level 14 they can be resized and user can - in limits - change the size. But that are Widgets not Shortcuts for launching icons.

You can use Intent

Intent mIntent = new Intent(FirstActivity.this, SecondActivity.class);
mIntent.putExtra("data", data);
startActivity(mIntent);

Another way could be using singleton pattern also:

public class DataHolder {

 private static DataHolder dataHolder;
 private List<Model> dataList;

 public void setDataList(List<Model>dataList) {
    this.dataList = dataList;
 }

 public List<Model> getDataList() {
    return dataList;
 }

 public synchronized static DataHolder getInstance() {
    if (dataHolder == null) {
       dataHolder = new DataHolder();
    }
    return dataHolder;
 }
}

From your FirstActivity

private List<Model> dataList = new ArrayList<>();
DataHolder.getInstance().setDataList(dataList);

On SecondActivity

private List<Model> dataList = DataHolder.getInstance().getDataList();

I've solved the same problem in a different way. I don't have data I waiting for it from the background thread so start with an emty list.

        mAdapter = new ModelAdapter(getContext(),new ArrayList<Model>());
   // then when i get data

        mAdapter.update(response.getModelList());
  //  and update is in my adapter

        public void update(ArrayList<Model> modelList){
            adapterModelList.clear(); 
            for (Product model: modelList) {
                adapterModelList.add(model); 
            }
           mAdapter.notifyDataSetChanged();
        }

That's it.

Yours:

  <div style="height:42px;width:42px">
  <img src="http://someimage.jpg">

Is it okay to use this code?

  <div class= "box">
  <img src= "http://someimage.jpg" class= "img">
  </div>

  <style type="text/css">
  .box{width: 42; height: 42;}
  .img{width: 20; height:20;}
  </style>

Just trying, though late. :3 For someone else reading this, letme know if the way i wrote the code were not good. im new in this kind of language. and i still want to learn more.

I had the same problem and after some searching I was able to find my logs at the following location:

C:\Users\<yourid>\.AndroidStudioPreview\system\log

//Data Table

 protected DataTable tblDynamic
        {
            get
            {
                return (DataTable)ViewState["tblDynamic"];
            }
            set
            {
                ViewState["tblDynamic"] = value;
            }
        }
//DynamicReport_GetUserType() function for getting data from DB


System.Data.DataSet ds = manage.DynamicReport_GetUserType();
                tblDynamic = ds.Tables[13];

//Add Column as "TypeName"

                tblDynamic.Columns.Add(new DataColumn("TypeName", typeof(string)));

//fill column data against ds.Tables[13]


                for (int i = 0; i < tblDynamic.Rows.Count; i++)
                {

                    if (tblDynamic.Rows[i]["Type"].ToString()=="A")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Apple";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "B")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Ball";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "C")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Cat";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "D")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Dog;
                    }
                }

Add @Controller to your controller or where ever you have the @RequestMapping for you json end point.

This worked for me while deploying a similar application.

You have to enable Type Name Handling and pass that to the (de)serializer as a settings parameter.

Base object1 = new Base() { Name = "Object1" };
Derived object2 = new Derived() { Something = "Some other thing" };
List<Base> inheritanceList = new List<Base>() { object1, object2 };

JsonSerializerSettings settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
string Serialized = JsonConvert.SerializeObject(inheritanceList, settings);
List<Base> deserializedList = JsonConvert.DeserializeObject<List<Base>>(Serialized, settings);

This will result in correct deserialization of derived classes. A drawback to it is that it will name all the objects you are using, as such it will name the list you are putting the objects in.

Yes basically this is what virtualenv do , and this is what the activate command is for, from the doc here:

activate script

In a newly created virtualenv there will be a bin/activate shell script, or a Scripts/activate.bat batch file on Windows.

This will change your $PATH to point to the virtualenv bin/ directory. Unlike workingenv, this is all it does; it's a convenience. But if you use the complete path like /path/to/env/bin/python script.py you do not need to activate the environment first. You have to use source because it changes the environment in-place. After activating an environment you can use the function deactivate to undo the changes.

The activate script will also modify your shell prompt to indicate which environment is currently active.

so you should just use activate command which will do all that for you:

> \path\to\env\bin\activate.bat

I think you misunderstood some core concepts about iOS modal view controllers. When you dismiss VC1, any presented view controllers by VC1 are dismissed as well. Apple intended for modal view controllers to flow in a stacked manner - in your case VC2 is presented by VC1. You are dismissing VC1 as soon as you present VC2 from VC1 so it is a total mess. To achieve what you want, buttonPressedFromVC1 should have the mainVC present VC2 immediately after VC1 dismisses itself. And I think this can be achieved without delegates. Something along the lines:

UIViewController presentingVC = [self presentingViewController];
[self dismissViewControllerAnimated:YES completion:
 ^{
    [presentingVC presentViewController:vc2 animated:YES completion:nil];
 }];

Note that self.presentingViewController is stored in some other variable, because after vc1 dismisses itself, you shouldn't make any references to it.

It could also be that you have a python3 system only. You therefore have installed the necessary packages via pip3 install , like pip3 install wheel.

You'll need to build your stuff using python3 specifically.

python3 setup.py sdist
python3 setup.py bdist_wheel

Cheers.

Example of Array length change method (with old data coping):

static int[] arrayLengthChange(int[] arr, int newLength) {
    int[] arrNew = new int[newLength];
    System.arraycopy(arr, 0, arrNew, 0, arr.length);
    return arrNew;
}

If you have any NamedQueries in your entity classes, then check the stack trace for compilation errors. A malformed query which cannot be compiled can cause failure to load the persistence context.

If you try exec sp_rename and receieve a LockMatchID error then it might help to add a use [database] statement first:

I tried

 exec sp_rename '[database_name].[dbo].[table_name]', 'new_table_name';
 -- Invalid EXECUTE statement using object "Object", method "LockMatchID".

What I had to do to fix it was to rewrite it to:

use database_name
exec sp_rename '[dbo].[table_name]', 'new_table_name';

I'm making a guess here, but your start invocation probably looks like this:

start "\Foo\Bar\Path with spaces in it\program.exe"

This will open a new console window, using “\Foo\Bar\Path with spaces in it\program.exe” as its title.

If you use start with something that is (or needs to be) surrounded by quotes, you need to put empty quotes as the first argument:

start "" "\Foo\Bar\Path with spaces in it\program.exe"

This is because start interprets the first quoted argument it finds as the window title for a new console window.

This worked for me. Search in your workspace for the text:

"../build/Release/bson"

You will probably find it inside the mongose and monk modules.

Then replace each:

bson = require('../build/Release/bson');

with:

bson = require('bson');

that's all!

You have to do this to echo it:

echo $row['note'];

(The data is coming as an array)

Use a second ArrayList for the 3 strings, not a primitive array. Ie.
private List<List<String>> addresses = new ArrayList<List<String>>();

Then you can have:

ArrayList<String> singleAddress = new ArrayList<String>();
singleAddress.add("17 Fake Street");
singleAddress.add("Phoney town");
singleAddress.add("Makebelieveland");

addresses.add(singleAddress);

(I think some strange things can happen with type erasure here, but I don't think it should matter here)

If you're dead set on using a primitive array, only a minor change is required to get your example to work. As explained in other answers, the size of the array can not be included in the declaration. So changing:

private ArrayList<String[]> addresses = new ArrayList<String[3]>();

to

private ArrayList<String[]> addresses = new ArrayList<String[]>();

will work.

You can write if, else if, else statements in short form. For example:

Boolean isCapital = city.isCapital(); //Object Boolean (not boolean)
String isCapitalName = isCapital == null ? "" : isCapital ? "Capital" : "City";      

This is short form of:

Boolean isCapital = city.isCapital();
String isCapitalName;
if(isCapital == null) {
    isCapitalName = "";
} else if(isCapital) {
    isCapitalName = "Capital";
} else {
    isCapitalName = "City";
}

• There is no runtime impact, as compiler automatically replaces the * with concrete class names. If you decompile the .class file, you would never see import ...*.

• C# always uses * (implicitly) as you can only using package name. You can never specify the class name at all. Java introduces the feature after c#. (Java is so tricky in many aspects but it's beyond this topic).

• In Intellij Idea when you do "organize imports", it automatically replaces multiple imports of the same package with *. This is a mandantory feature as you can not turn it off (though you can increase the threshold).

• The case listed by the accepted reply is not valid. Without * you still got the same issue. You need specify the pakcage name in your code no matter you use * or not.

In my case, I was working on a web api project and although the project was set correctly to full debug, I was still seeing this error every time I attached to the IIS process I was trying to debug. Then I realized the publish profile was set to use the Release configuration. So one more place to check is your publish profile if you're using the 'Publish' feature of your dotnet web api project.

If you are working on your own, and you want the closest thing to OOP as you would find in Java or C# or C++, see the javascript library, CrxOop. CrxOop provides syntax somewhat familiar to Java developers.

Just be careful, Java's OOP is not the same as that found in Javascript. To get the same behavior as in Java, use CrxOop's classes, not CrxOop's structures, and make sure all your methods are virtual. An example of the syntax is,

crx_registerClass("ExampleClass", 
{ 
    "VERBOSE": 1, 

    "public var publicVar": 5, 
    "private var privateVar": 7, 

    "public virtual function publicVirtualFunction": function(x) 
    { 
        this.publicVar1 = x;
        console.log("publicVirtualFunction"); 
    }, 

    "private virtual function privatePureVirtualFunction": 0, 

    "protected virtual final function protectedVirtualFinalFunction": function() 
    { 
        console.log("protectedVirtualFinalFunction"); 
    }
}); 

crx_registerClass("ExampleSubClass", 
{ 
    VERBOSE: 1, 
    EXTENDS: "ExampleClass", 

    "public var publicVar": 2, 

    "private virtual function privatePureVirtualFunction": function(x) 
    { 
        this.PARENT.CONSTRUCT(pA);
        console.log("ExampleSubClass::privatePureVirtualFunction"); 
    } 
}); 

var gExampleSubClass = crx_new("ExampleSubClass", 4);

console.log(gExampleSubClass.publicVar);
console.log(gExampleSubClass.CAST("ExampleClass").publicVar);

The code is pure javascript, no transpiling. The example is taken from a number of examples from the official documentation.

Here is an example where pointer to data members could be useful:

#include <iostream>
#include <list>
#include <string>

template <typename Container, typename T, typename DataPtr>
typename Container::value_type searchByDataMember (const Container& container, const T& t, DataPtr ptr) {
    for (const typename Container::value_type& x : container) {
        if (x->*ptr == t)
            return x;
    }
    return typename Container::value_type{};
}

struct Object {
    int ID, value;
    std::string name;
    Object (int i, int v, const std::string& n) : ID(i), value(v), name(n) {}
};

std::list<Object*> objects { new Object(5,6,"Sam"), new Object(11,7,"Mark"), new Object(9,12,"Rob"),
    new Object(2,11,"Tom"), new Object(15,16,"John") };

int main() {
    const Object* object = searchByDataMember (objects, 11, &Object::value);
    std::cout << object->name << '\n';  // Tom
}

For getting the buffer size in c/c++ program the following is the flow

int n;
unsigned int m = sizeof(n);
int fdsocket;
fdsocket = socket(AF_INET,SOCK_DGRAM,IPPROTO_UDP); // example
getsockopt(fdsocket,SOL_SOCKET,SO_RCVBUF,(void *)&n, &m);
// now the variable n will have the socket size

The code is valid (i.e, will compile and execute) in both cases.

One of my lecturers at Uni told us that it is not desirable to have continue, return statements in any loop - for or while. The reason for this is that when examining the code, it is not not immediately clear whether the full length of the loop will be executed or the return or continue will take effect.

See Why is continue inside a loop a bad idea? for an example.

The key point to keep in mind is that for simple scenarios like this it doesn't (IMO) matter but when you have complex logic determining the return value, the code is 'generally' more readable if you have a single return statement instead of several.

With regards to the Garbage Collection - I have no idea why this would be an issue.

The best way to answer your question is to see it in action.

<a id="test" onclick="alert('test')"> test </a> ?

In the js

var test = document.getElementById('test');
console.log( test.onclick ); 

As you see in the console, if you're using chrome it prints an anonymous function with the event object passed in, although it's a little different in IE.

function onclick(event) {
   alert('test')
}

I agree with some of your points about inline event handlers. Yes they are easy to write, but i don't agree with your point about having to change code in multiple places, if you structure your code well, you shouldn't need to do this.

The Bitmap class is an implementation of the Image class. The Image class is an abstract class;

The Bitmap class contains 12 constructors that construct the Bitmap object from different parameters. It can construct the Bitmap from another bitmap, and the string address of the image.

See more in this comprehensive sample.

Here is another method, much simple, lets say your dataframe name is daat and column name is YEARMONTH

daat.YEARMONTH.value_counts()

Well, Pavel was close, but there's even a more simple and elegant solution to initialize a sequential container from a c style array.

In your case:

w_ (array, std::end(array))

• array will get us a pointer to the beginning of the array (didn't catch it's name),
• std::end(array) will get us an iterator to the end of the array.

You can also toggleText by using toggleClass() as a thought ..

.myclass::after {
 content: 'more';
}
.myclass.opened::after {
 content: 'less';
}

And then use

$(myobject).toggleClass('opened');

To round out the possibilities, you can use writeLines() with sink(), if you want:

> sink("tempsink", type="output")
> writeLines("Hello\nWorld")

Hello
World

To me, it always seems most intuitive to use print(), but if you do that the output won't be what you want:

...
> print("Hello\nWorld")
...
[1] "Hello\nWorld"

It looks like the best approach is to use:

ContextCompat.getColor(context, R.color.color_name)

eg:

yourView.setBackgroundColor(ContextCompat.getColor(applicationContext,
                            R.color.colorAccent))

This will choose the Marshmallow two parameter method or the pre-Marshmallow method appropriately.

This does not work in Chrome Developer tools to locate a element, i am looking to locate the 'Submit' button in the screen

//input[matches(@value,'submit','i')]

However, using 'translate' to replace all caps to small works as below

//input[translate(@value,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz') = 'submit']

Update: I just found the reason why 'matches' doesnt work. I am using Chrome with xpath 1.0 which wont understand the syntax 'matches'. It should be xpath 2.0

an alternate option, which may or may not be suitable, but cleaner if it is:

If you always want to just print the iframe from the page, you can have a separate "@media print{}" stylesheet that hides everything besides the iframe. Then you can just print the page normally.

Try this regex:

\d+\.?\d*

\d+ digits before optional decimal
.? optional decimal(optional due to the ? quantifier)
\d* optional digits after decimal

You can either do:

plt.show(hold=False)
plt.savefig('name.pdf')

and remember to let savefig finish before closing the GUI plot. This way you can see the image beforehand.

Alternatively, you can look at it with plt.show() Then close the GUI and run the script again, but this time replace plt.show() with plt.savefig().

Alternatively, you can use

fig, ax = plt.figure(nrows=1, ncols=1)
plt.plot(...)
plt.show()
fig.savefig('out.pdf')

Solution #1: Python builtin

use SequenceMatcher from difflib

pros: native python library, no need extra package.
cons: too limited, there are so many other good algorithms for string similarity out there.

>>> from difflib import SequenceMatcher
>>> s = SequenceMatcher(None, "abcd", "bcde")
>>> s.ratio()
0.75

Solution #2: jellyfish library

its a very good library with good coverage and few issues. it supports:
- Levenshtein Distance
- Damerau-Levenshtein Distance
- Jaro Distance
- Jaro-Winkler Distance
- Match Rating Approach Comparison
- Hamming Distance

pros: easy to use, gamut of supported algorithms, tested.
cons: not native library.

example:

>>> import jellyfish
>>> jellyfish.levenshtein_distance(u'jellyfish', u'smellyfish')
2
>>> jellyfish.jaro_distance(u'jellyfish', u'smellyfish')
0.89629629629629637
>>> jellyfish.damerau_levenshtein_distance(u'jellyfish', u'jellyfihs')
1

This would remove the appended characters to your url

<script type="text/javascript">
 var idx=window.location.toString().indexOf("#_=_"); 
   if (idx > 0) { 
     window.location = window.location.toString().substring(0, idx); 
   } 
</script>

Essentially, it's the way Microsoft introduces its C++ extensions so that they won't conflict with future extensions of standard C++. With __declspec, you can attribute a function or class; the exact meaning varies depending on the nature of __declspec. __declspec(naked), for example, suppresses prolog/epilog generation (for interrupt handlers, embeddable code, etc), __declspec(thread) makes a variable thread-local, and so on.

The full list of __declspec attributes is available on MSDN, and varies by compiler version and platform.

ChangeDetectorRef.detectChanges() is usually the most focused way of doing this. ApplicationRef.tick() is usually too much of a sledgehammer approach.

To use ChangeDetectorRef.detectChanges(), you'll need this at the top of your component:

import {  ChangeDetectorRef } from '@angular/core';

... then, usually you alias that when you inject it in your constructor like this:

constructor( private cdr: ChangeDetectorRef ) { ... }

Then, in the appropriate place, you call it like this:

this.cdr.detectChanges();

Where you call ChangeDetectorRef.detectChanges() can be highly significant. You need to completely understand the life cycle and exactly how your application is functioning and rendering its components. There's no substitute here for completely doing your homework and making sure you understand the Angular lifecycle inside out. Then, once you understand that, you can use ChangeDetectorRef.detectChanges() appropriately (sometimes it's very easy to understand where you should use it, other times it can be very complex).

Easy solution for whom using VS Code

I've been getting this error for a while. Most of the answers works. But I found a different solution. If you don't want to deal with node.js or any other solution in here and you are working with an HTML file (calling functions from another js file or fetch json api's) try to use Live Server extension.

It allows you to open a live server easily. And because of it creates localhost server, the problem is resolving. You can simply start the localhost by open a HTML file and right-click on the editor and click on Open with Live Server.

It basically load the files using http://localhost/index.html instead of using file://....

EDIT

It is not necessary to have a .html file. You can start the Live Server with shortcuts.

Hit (alt+L, alt+O) to Open the Server and (alt+L, alt+C) to Stop the server. [On MAC, cmd+L, cmd+O and cmd+L, cmd+C]

Hope it will help someone :)

For jQuery, do you mean like this?

$('#object').css('display');

You can check it like this:

if($('#object').css('display') === 'block')
{
    //do something
}
else
{
    //something else
}

Most likely both tables have a column with the same name. Alias each table, and call each column with the table alias.

Another option is GhostDriver which is now officially supported by WebDriver: Ghostdriver actual performance gain

BootFlat

You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:

Another option is to get a ".pem" (public key) file for that particular server, and install it locally into the heart of your JRE's "cacerts" file (use the keytool helper application), then it will be able to download from that server without complaint, without compromising the entire SSL structure of your running JVM and enabling download from other unknown cert servers...

You could use application preferences. They are accessible from any activity or piece of code as long as you pass on the Context object, and they are private to the application that uses them, so you don't need to worry about exposing application specific values, unless you deal with routed devices. Even so, you could use hashing or encryption schemes to save the values. Also, these preferences are stored from an application run to the next. Here is some code examples that you can look at.

Here is what I did

private void myEvent_Handler(object sender, SomeEvent e)
{
  // I dont know how many times this event will fire
  Task t = new Task(() =>
  {
    if (something == true) 
    {
        DoSomething(e);  
    }
  });
  t.RunSynchronously();
}

working great and not blocking UI thread

Singleton beans in Spring and classes based on Singleton design pattern are quite different.

Singleton pattern ensures that one and only one instance of a particular class will ever be created per classloader where as the scope of a Spring singleton bean is described as 'per container per bean'. Singleton scope in Spring means that this bean will be instantiated only once by Spring. Spring container merely returns the same instance again and again for subsequent calls to get the bean.

Our DMS Software Reengineering Toolkit has static control/dataflow/points-to/call graph analysis that has been applied to huge systems (~~25 million lines) of C code, and produced such call graphs, including functions called via function pointers.

I know that two threads can not enter in Synchronize block at the same time

Two thread cannot enter a synchronized block on the same object twice. This means that two threads can enter the same block on different objects. This confusion can lead to code like this.

private Integer i = 0;

synchronized(i) {
   i++;
}

This will not behave as expected as it could be locking on a different object each time.

if this is true than How this atomic.incrementAndGet() works without Synchronize ?? and is thread safe ??

yes. It doesn't use locking to achieve thread safety.

If you want to know how they work in more detail, you can read the code for them.

And what is difference between internal reading and writing to Volatile Variable / Atomic Variable ??

Atomic class uses volatile fields. There is no difference in the field. The difference is the operations performed. The Atomic classes use CompareAndSwap or CAS operations.

i read in some article that thread has local copy of variables what is that ??

I can only assume that it referring to the fact that each CPU has its own cached view of memory which can be different from every other CPU. To ensure that your CPU has a consistent view of data, you need to use thread safety techniques.

This is only an issue when memory is shared at least one thread updates it.

Let me tell you step by step few years back I was in same situation.

So We have two Phases

1. iPhone/iPad (iOS) app development
2. iPhone/iPad (iOS) app development and Publish to iTunes Store

1. iPhone/iPad (iOS) app development

So If you just want to develop iOS apps you don't want to pay anything,

You just need Mac + XCode IDE

1. Get Mac Mini or Mac Machine
2. Create Developer Account on Apple its free
3. After login developer account you can download Xcode IDE's .dmg file
4. That's all.

Now you just install Xcode and start developing iOS apps and test/debug with Simulator..

2. iPhone/iPad (iOS) app development and Publish to iTunes Store

for publishing your app on iTunes store you need to pay (example $99 / year) .

So For complete iOS Development Setup you need

1. Get Mac Mini or Mac Machine
2. Create Developer Account on Apple its free
3. After login developer account you can download Xcode IDE's .dmg file
4. pay $99 for publish apps on iTunes
5. create your certificates for development/distribution on your apple account
6. download all certificate on mac machine and install into XCode using Keychain tool
7. Get at least one iOS Device
8. Register you device on your apple account
9. Now you can develop iOS app, test on Real Device and also publish on iTunes Store

using pip:

pip install mechanize

or download the mechanize distribution archive, open it, and run:

python setup.py install

U need replace it with new file input. Here is how it can be done with jQuery:

var inputFile = $('input[type=field]');
inputFile.wrap('<div />');

and use this line when you need to clear input field (on some event for example):

inputFile.parent().html( inputFile.parent().html() );

@PostConstruct is run ONCE in first when Bean Created. the solution is create a Unused property and Do your Action in Getter method of this property and add this property to your .xhtml file like this :

<h:inputHidden  value="#{loginBean.loginStatus}"/>

and in your bean code:

public void setLoginStatus(String loginStatus) {
    this.loginStatus = loginStatus;
}

public String getLoginStatus()  {
    // Do your stuff here.
    return loginStatus;
}

TL;DR Check the network mode of your VirtualBox host - it should be bridged if you want the virtual machine (and the Docker container it's hosting) accessible on your local network.

It sounds like your confusion lies in which host to connect to in order to access your application via HTTP. You haven't really spelled out what your configuration is - I'm going to make some guesses, based on the fact that you've got "Windows" and "VirtualBox" in your tags.

I'm guessing that you have Docker running on some flavour of Linux running in VirtualBox on a Windows host. I'm going to label the IP addresses as follows:

D = the IP address of the Docker container

L = the IP address of the Linux host running in VirtualBox

W = the IP address of the Windows host

When you run your Go application on your Windows host, you can connect to it with http://W:8080/ from anywhere on your local network. This works because the Go application binds the port 8080 on the Windows machine and anybody who tries to access port 8080 at the IP address W will get connected.

And here's where it becomes more complicated:

VirtualBox, when it sets up a virtual machine (VM), can configure the network in one of several different modes. I don't remember what all the different options are, but the one you want is bridged. In this mode, VirtualBox connects the virtual machine to your local network as if it were a stand-alone machine on the network, just like any other machine that was plugged in to your network. In bridged mode, the virtual machine appears on your network like any other machine. Other modes set things up differently and the machine will not be visible on your network.

So, assuming you set up networking correctly for the Linux host (bridged), the Linux host will have an IP address on your local network (something like 192.168.0.x) and you will be able to access your Docker container at http://L:8080/.

If the Linux host is set to some mode other than bridged, you might be able to access from the Windows host, but this is going to depend on exactly what mode it's in.

EDIT - based on the comments below, it sounds very much like the situation I've described above is correct.

Let's back up a little: here's how Docker works on my computer (Ubuntu Linux).

Imagine I run the same command you have: docker run -p 8080:8080 dockertest. What this does is start a new container based on the dockertest image and forward (connect) port 8080 on the Linux host (my PC) to port 8080 on the container. Docker sets up it's own internal networking (with its own set of IP addresses) to allow the Docker daemon to communicate and to allow containers to communicate with one another. So basically what you're doing with that -p 8080:8080 is connecting Docker's internal networking with the "external" network - ie. the host's network adapter - on a particular port.

With me so far? OK, now let's take a step back and look at your system. Your machine is running Windows - Docker does not (currently) run on Windows, so the tool you're using has set up a Linux host in a VirtualBox virtual machine. When you do the docker run in your environment, exactly the same thing is happening - port 8080 on the Linux host is connected to port 8080 on the container. The big difference here is that your Windows host is not the Linux host on which the container is running, so there's another layer here and it's communication across this layer where you are running into problems.

What you need is one of two things:

1. to connect port 8080 on the VirtualBox VM to port 8080 on the Windows host, just like you connect the Docker container to the host port.

2. to connect the VirtualBox VM directly to your local network with the bridged network mode I described above.

If you go for the first option, you will be able to access the container at http://W:8080 where W is the IP address or hostname of the Windows host. If you opt for the second, you will be able to access the container at http://L:8080 where L is the IP address or hostname of the Linux VM.

So that's all the higher-level explanation - now you need to figure out how to change the configuration of the VirtualBox VM. And here's where I can't really help you - I don't know what tool you're using to do all this on your Windows machine and I'm not at all familiar with using Docker on Windows.

If you can get to the VirtualBox configuration window, you can make the changes described below. There is also a command line client that will modify VMs, but I'm not familiar with that.

For bridged mode (and this really is the simplest choice), shut down your VM, click the "Settings" button at the top, and change the network mode to bridged, then restart the VM and you're good to go. The VM should pick up an IP address on your local network via DHCP and should be visible to other computers on the network at that IP address.

In flutter 1.5 and Dart 2.3 for visibility gone, You can set the visibility by using an if statement within the collection without having to make use of containers.

e.g

child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
              Text('This is text one'),
              if (_isVisible) Text('can be hidden or shown'), // no dummy container/ternary needed
              Text('This is another text'),
              RaisedButton(child: Text('show/hide'), onPressed: (){
                  setState(() {
                    _isVisible = !_isVisible; 
                  });
              },)

          ],
        )

• Matcher.find and Files.walk methods could be an option to search files in more flexible way
• String.format combines regular expressions to create search restrictions
• Files.isRegularFile checks if a path is't directory, symbolic link, etc.

Usage:

//Searches file names (start with "temp" and extension ".txt")
//in the current directory and subdirectories recursively
Path initialPath = Paths.get(".");
PathUtils.searchRegularFilesStartsWith(initialPath, "temp", ".txt").
                                       stream().forEach(System.out::println);

If you want to do this kind of testing, you’ll love the UI Automation support in iOS 4. You can write JavaScript to simulate button presses, etc. fairly easily, though the documentation (especially the getting-started part) is a bit sparse.

gcc 9.3 asm output, without using optimisation flags (everything in this answer refers to standard compilation without optimisation flags):

#include <stdio.h>
int main(void) {
  int i = 3;
  i++;
  printf("%d", i);
  return 0;
}

.LC0:
        .string "%d"
main:
        push    rbp
        mov     rbp, rsp
        sub     rsp, 16
        mov     DWORD PTR [rbp-4], 3
        add     DWORD PTR [rbp-4], 1
        mov     eax, DWORD PTR [rbp-4]
        mov     esi, eax
        mov     edi, OFFSET FLAT:.LC0
        mov     eax, 0
        call    printf
        mov     eax, 0
        leave 
        ret

#include <stdio.h>
int main(void) {
  register int i = 3;
  i++;
  printf("%d", i);
  return 0;
}

.LC0:
        .string "%d"
main:
        push    rbp
        mov     rbp, rsp
        push    rbx
        sub     rsp, 8
        mov     ebx, 3
        add     ebx, 1
        mov     esi, ebx
        mov     edi, OFFSET FLAT:.LC0
        mov     eax, 0
        call    printf
        add     rsp, 8
        pop     rbx
        pop     rbp
        ret

This forces ebx to be used for the calculation, meaning it needs to be pushed to the stack and restored at the end of the function because it is callee saved. register produces more lines of code and 1 memory write and 1 memory read (although realistically, this could have been optimised to 0 R/Ws if the calculation had been done in esi, which is what happens using C++'s const register). Not using register causes 2 writes and 1 read (although store to load forwarding will occur on the read). This is because the value has to be present and updated directly on the stack so the correct value can be read by address (pointer). register doesn't have this requirement and cannot be pointed to. const and register are basically the opposite of volatile and using volatile will override the const optimisations at file and block scope and the register optimisations at block-scope. const register and register will produce identical outputs because const does nothing on C at block-scope, so only the register optimisations apply.

On clang, register is ignored but const optimisations still occur.

Array list can be implemented by the following code:

Arraylist<String> list = new ArrayList<String>();
list.add(value1);
list.add(value2);
list.add(value3);
list.add(value4);

If you are sending multiple objects, it's often simplest to put them some kind of holder/collection like an Object[] or List. It saves you having to explicitly check for end of stream and takes care of transmitting explicitly how many objects are in the stream.

EDIT: Now that I formatted the code, I see you already have the messages in an array. Simply write the array to the object stream, and read the array on the server side.

Your "server read method" is only reading one object. If it is called multiple times, you will get an error since it is trying to open several object streams from the same input stream. This will not work, since all objects were written to the same object stream on the client side, so you have to mirror this arrangement on the server side. That is, use one object input stream and read multiple objects from that.

(The error you get is because the objectOutputStream writes a header, which is expected by objectIutputStream. As you are not writing multiple streams, but simply multiple objects, then the next objectInputStream created on the socket input fails to find a second header, and throws an exception.)

To fix it, create the objectInputStream when you accept the socket connection. Pass this objectInputStream to your server read method and read Object from that.

        hmap.put("1", "Bala");
        hmap.put("2", "Test");

        Boolean cantain = hmap.containsValue("Bala");
        if(hmap.containsKey("2") && hmap.containsValue("Test"))
        {
            System.out.println("Yes");
        }
        if(cantain == true)
        {
            System.out.println("Yes"); 
        }

        Set setkeys = hmap.keySet();
        Iterator it = setkeys.iterator();

        while(it.hasNext())
        {
            String key = (String) it.next();
            if (hmap.get(key).equals("Bala"))
            {
                System.out.println(key);
            }
        }

As of npm version 3.8.6, you can use

npm install --prefix ./install/here <package>

to install in the specified directory. NPM automatically creates node_modules folder even when a node_modules directory already exists in the higher up hierarchy. You can also have a package.json in the current directory and then install it in the specified directory using --prefix option:

npm install --prefix ./install/here

As of npm 6.0.0, you can use

npm install --prefix ./install/here ./

to install the package.json in current directory to "./install/here" directory. There is one thing that I have noticed on Mac that it creates a symlink to parent folder inside the node_modules directory. But, it still works.

NOTE: NPM honours the path that you've specified through the --prefix option. It resolves as per npm documentation on folders, only when npm install is used without the --prefix option.

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;

        }
        return result;

                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;

        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

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

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

You should use the HasValue property:

SomeProperty.HasValue

For example:

if (SomeProperty.HasValue)
{
    // Do Something
}
else
{
    // Do Something Else
}

FYI

public Nullable<System.Guid> SomeProperty { get; set; }

is equivalent to:

public System.Guid? SomeProperty { get; set; }

Q: The programming model is event driven, especially the way it handles I/O.

Correct. It uses call-backs, so any request to access the file system would cause a request to be sent to the file system and then Node.js would start processing its next request. It would only worry about the I/O request once it gets a response back from the file system, at which time it will run the callback code. However, it is possible to make synchronous I/O requests (that is, blocking requests). It is up to the developer to choose between asynchronous (callbacks) or synchronous (waiting).

Q: It uses JavaScript and the parser is V8.

Yes

Q: It can be easily used to create concurrent server applications.

Yes, although you'd need to hand-code quite a lot of JavaScript. It might be better to look at a framework, such as http://www.easynodejs.com/ - which comes with full online documentation and a sample application.

You can use git show with a path from the root of the repository (./ or ../ for relative pathing):

$ git show REVISION:path/to/file

Replace REVISION with your actual revision (could be a Git commit SHA, a tag name, a branch name, a relative commit name, or any other way of identifying a commit in Git)

For example, to view the version of file <repository-root>/src/main.c from 4 commits ago, use:

$ git show HEAD~4:src/main.c

Git for Windows requires forward slashes even in paths relative to the current directory. For more information, check out the man page for git-show.

You can simply assign it a new value as follows,

window.location.hash

I have been puzzled a lot with this problem, since I am relively new in Python. I cannot apply the solution to the code given by the questioned, since it's not self executable. So I bring a very simple code:

from turtle import *

ts = Screen(); tu = Turtle()

def move(x,y):
  print "move()"
  tu.goto(100,100)

ts.listen();
ts.onclick(move)

done()

As you can see, the solution consists in using two (dummy) arguments, even if they are not used either by the function itself or in calling it! It sounds crazy, but I believe there must be a reason for it (hidden from the novice!).

I have tried a lot of other ways ('self' included). It's the only one that works (for me, at least).

If you just want see the output of the process running from within the container, you can do a simple docker container logs -f <container id>.

The -f flag makes it so that the output of the container is followed and updated in real-time. Very useful for debugging or monitoring.

if (StartDate>=EndDate)
{
    throw new InvalidOperationException("Ack!  StartDate is not before EndDate!");
}

I found another situation in which this problem may arise (despite following the steps listed by other users above) and that's when the username of the user you're logged in as has an '_' on it. The path it will try to use to find the temp directory is whatever is set in %TEMP%. I managed to work around it by:

1. Launch cmd.exe in Administrator mode
2. SET TEMP = C:\TEMP
3. Run the installer from that command window

Installed successfully that way.

If it's a DNS problem, you could try:

• ipconfig /flushdns
• ipconfig /registerdns

If this doesn't fix it, you could try editing the hosts file located here:

C:\Windows\System32\drivers\etc\hosts

And ensure that this line (and no other line referencing localhost) is in there:

127.0.0.1 localhost

I used following code on my sample application to start new activity.

Button next = (Button) findViewById(R.id.TEST);
next.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
        Intent myIntent = new Intent( view.getContext(), MyActivity.class);
        startActivityForResult(myIntent, 0);
    }
});

When you restore backup, Make sure to try with the same username for the old one and the new one.

In answer to your general question of

So I am curious: What did I do to disorientate migrations? And what can I do to get it working with just one initial migration?

I've just had the same error message as you after I merged several branches and the migrations got confused about the current state of the database. Worst of all, this was only happening on the client's server, not on our development systems.

In trying to work out what was happening there, I came across this superb Microsoft guide:

Microsoft's guide to Code First Migrations in Team Environments

Whilst that guide was written to explain migrations in teams, it also gives the best explanation I've found of how the migrations work internally, which may well lead to an explanation for the behaviour your seeing. It's very worth putting an hour aside to read all of that for anyone who works with EF6 or below.

For anyone brought to this question by that error message after merging migrations, the trick of generating a blank migration with the current state of the database solved things for me, but do be very sure to have read the whole guide to know if that solution is appropriate in your case.

You can simply use:

mvn --settings YourOwnSettings.xml clean install

or

mvn -s YourOwnSettings.xml clean install

You need to use background-image instead of backgroundImage. For example:

$(function() {
  $('.home').click(function() {
    $(this).css('background-image', 'url(images/tabs3.png)');
  });
}):

The smarter_csv gem was specifically created for this use-case: to read data from CSV file and quickly create database entries.

  require 'smarter_csv'
  options = {}
  SmarterCSV.process('input_file.csv', options) do |chunk|
    chunk.each do |data_hash|
      Moulding.create!( data_hash )
    end
  end

You can use the option chunk_size to read N csv-rows at a time, and then use Resque in the inner loop to generate jobs which will create the new records, rather than creating them right away - this way you can spread the load of generating entries to multiple workers.

I saw this error in combination with the PageSpeed module enabled. The PageSpeed module has a cache that can be gzip compressed. So apparently what can happen is that content gets double compressed.

In order to rewrite resources, PageSpeed must cache them server-side. Until 1.10.33.0, these resources had been stored uncompressed. To reduce disk usage, decrease server latency, support higher compression levels, and increase server throughput, the HTTPCache can automatically gzip compressable resources as they are stored in the cache. To configure cache compression, set HttpCacheCompressionLevel to values between -1 and 9, with 0 being off, -1 being gzip's default compression, and 9 being maximum compression. The default value is 9, maximum compression.

I solved it by adding this line to my PageSpeed config:

HttpCacheCompressionLevel 0

which disables the compression.

I didn't want to delete all the packages in vendor/ directory, so here is how I did it:

1. rm -rf vendor/package-i-messed-up
2. composer install again

The Servlet 3.0 spec doesn't seem to provide a hint on how a container should order filters that have been declared via annotations. It is clear how about how to order filters via their declaration in the web.xml file, though.

Be safe. Use the web.xml file order filters that have interdependencies. Try to make your filters all order independent to minimize the need to use a web.xml file.

Using $_SERVER['HTTP_REFERER']

The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.

if (!empty($_SERVER['HTTP_REFERER'])) {
    header("Location: " . $_SERVER['HTTP_REFERER']);
} else {
    header("Location: index.php");
}
exit;

SQL Server 2005 and later allow you to create your own custom aggregate functions, including for things like concatenation- see the sample at the bottom of the linked article.

That works better with this :

var a = fso.CreateTextFile("c:\\testfile.txt", true);
a.WriteLine("This is a test.");
a.Close();

Was tested on 100 000 records: Time in seconds(calculated by funciton microtime). Only for unique values on sorting key positions.

Solution of function of @Josh Davis: Spended time: 1.5768740177155

Mine solution: Spended time: 0.094044923782349

Solution:

function SortByKeyValue($data, $sortKey, $sort_flags=SORT_ASC)
{
    if (empty($data) or empty($sortKey)) return $data;

    $ordered = array();
    foreach ($data as $key => $value)
        $ordered[$value[$sortKey]] = $value;

    ksort($ordered, $sort_flags);

    return array_values($ordered); *// array_values() added for identical result with multisort*

I think this has problems with empty directories but if another poster has a tweak I'll update my answer. Also, you may already know this but this is probably be a good candidate for an alias given it's lengthiness.

[update] added some tweaks based on comments, thanks guys.

[update] as pointed out by the comments you may need to tweek the matcher expressions depending on the shell (bash vs zsh). I've re-added my older command for reference.

This is a common way to do it:

long l = Long.parseLong(str);

There is also this method: Long.valueOf(str); Difference is that parseLong returns a primitive long while valueOf returns a new Long() object.

If you want a newline, you have to write one explicitly. The usual way is like this:

hs.write(name + "\n")

This uses a backslash escape, \n, which Python converts to a newline character in string literals. It just concatenates your string, name, and that newline character into a bigger string, which gets written to the file.

It's also possible to use a multi-line string literal instead, which looks like this:

"""
"""

Or, you may want to use string formatting instead of concatenation:

hs.write("{}\n".format(name))

All of this is explained in the Input and Output chapter in the tutorial.

>>> from datetime import datetime
>>> print(datetime.today().strftime("%H:%M %p"))
15:31 AM

Try replacing %I with %H.

In the book of Matt Stauffer he suggest to create an array in your config/app.php to add the variable and then anywhere you reference to it with:

$myvariable = new Namearray(config('fileWhichContainsVariable.array.ConfigKeyVariable'))

What your looking for is the DefaultListModel - Dynamic String List Variable.

Here is a whole class that uses the DefaultListModel as though it were the TStringList of Delphi. The difference is that you can add Strings to the list without limitation and you have the same ability at getting a single entry by specifying the entry int.

OutputAs methods are for outputting an entry as int, double, etc... so that you don't have to convert from string on the other side.

SaveFile & LoadFile are to save and load strings to and from files.

StrToList & ListToStr are to place delimiters between each entry.

ex. 1<>2<>3<>4<> if "<>" is the delimiter and 1 2 3 & 4 are the entries.

AddEntry & GetEntry are to add and get strings to and from the DefaultListModel.

RemoveEntry is to delete a string from the DefaultListModel.

You use the DefaultListModel instead of an array here like this:

DefaultListModel list = new DefaultListModel();
//now that you have a list, you can run it through the above class methods.

Preferably put in a Util.java class

public static float dpFromPx(final Context context, final float px) {
    return px / context.getResources().getDisplayMetrics().density;
}

public static float pxFromDp(final Context context, final float dp) {
    return dp * context.getResources().getDisplayMetrics().density;

After all these awesome answers, I hope my answer finds someone and helps them out. I wrote a small service to keep track of route history. Here it goes.

@Injectable()
export class RouteInterceptorService {

  private _routeHistory: string[];

  constructor(router: Router) {
    this._routeHistory = [];
    router.events
      .pipe(filter(event => event instanceof NavigationEnd))
      .subscribe((event: NavigationEnd) => {
        this._setURLs(event);
      });
  }

  private _setURLs(event: NavigationEnd): void {
    const tempUrl = this._currentUrl;
    this._previousUrl = tempUrl;
    this._currentUrl = event.urlAfterRedirects;
    this._routeHistory.push(event.urlAfterRedirects);
  }

  get previousUrl(): string {
    return this._previousUrl;

On a Windows host

open a CMD prompt;

set HTTP_PROXY=http://proxy.yourcorp.com:80
set HTTPS_PROXY=https://proxy.yourcorp.com:443

Substitute the address and port in the above snippets to whatever is appropriate for your situation. The above will remain set until you close the CMD prompt. If it works for you, consider adding them permanently to your environment variables so that you won't have to set them every time you open a new CMD prompt.

You must add "include fastcgi.conf" in

location ~ \.$php{
  #......
  include fastcgi.conf;
}

You can export the private key with the command-line tool from GPG. It works on the Windows-shell. Use the following command:

gpg --export-secret-keys

A normal export with --export will not include any private keys, therefore you have to use --export-secret-keys.

Edit:

To sum up the information given in my comments, this is the command that allows you to export a specific key with the ID 1234ABCD to the file secret.asc:

gpg --export-secret-keys --armor 1234ABCD > secret.asc

You can find the ID that you need using the following command. The ID is the second part of the second column:

gpg --list-keys

To Export just 1 specific secret key instead of all of them:

gpg --export-secret-keys keyIDNumber > exportedKeyFilename.asc

keyIDNumber is the number of the key id for the desired key you are trying to export.

There are valid differences between types of architects:

Enterprise architects look at solutions for the enterprise aligining tightly with the enterprise strategy. Eg in a bank, they'll look at the complete IT landscape.

Solution architects focus on a particular solution, for example a new credit card acquiring system in a bank.

Domain architects focus on specific areas, for example an application architect or network architect.

Technical architects generally play the role of solution architects with less focus on the business aspect and more on the techology aspect.

I needed an elegant solution for the busybox (router), all xargs or array solutions were useless to me - no such command available there. find and mtime is not the proper answer as we are talking about 10 items and not necessarily 10 days. Espo's answer was the shortest and cleanest and likely the most unversal one.

Error with spaces and when no files are to be deleted are both simply solved the standard way:

rm "$(ls -td *.tar | awk 'NR>7')" 2>&-

Bit more educational version: We can do it all if we use awk differently. Normally, I use this method to pass (return) variables from the awk to the sh. As we read all the time that can not be done, I beg to differ: here is the method.

Example for .tar files with no problem regarding the spaces in the filename. To test, replace "rm" with the "ls".

eval $(ls -td *.tar | awk 'NR>7 { print "rm \"" $0 "\""}')

Explanation:

ls -td *.tar lists all .tar files sorted by the time. To apply to all the files in the current folder, remove the "d *.tar" part

awk 'NR>7... skips the first 7 lines

print "rm \"" $0 "\"" constructs a line: rm "file name"

eval executes it

Since we are using rm, I would not use the above command in a script! Wiser usage is:

(cd /FolderToDeleteWithin && eval $(ls -td *.tar | awk 'NR>7 { print "rm \"" $0 "\""}'))

In the case of using ls -t command will not do any harm on such silly examples as: touch 'foo " bar' and touch 'hello * world'. Not that we ever create files with such names in real life!

Sidenote. If we wanted to pass a variable to the sh this way, we would simply modify the print (simple form, no spaces tolerated):

print "VarName="$1

to set the variable VarName to the value of $1. Multiple variables can be created in one go. This VarName becomes a normal sh variable and can be normally used in a script or shell afterwards. So, to create variables with awk and give them back to the shell:

eval $(ls -td *.tar | awk 'NR>7 { print "VarName=\""$1"\""  }'); echo "$VarName"

I have redesigned the code for phone numbers +9 (987) 124124 Extract digits from a string in Java

 public static String stripNonDigitsV2( CharSequence input ) {
    if (input == null)
        return null;
    if ( input.length() == 0 )
        return "";

    char[] result = new char[input.length()];
    int cursor = 0;
    CharBuffer buffer = CharBuffer.wrap( input );
    int i=0;
    while ( i< buffer.length()  ) { //buffer.hasRemaining()
        char chr = buffer.get(i);
        if (chr=='u'){
            i=i+5;
            chr=buffer.get(i);
        }

        if ( chr > 39 && chr < 58 )
            result[cursor++] = chr;
        i=i+1;
    }

    return new String( result, 0, cursor );
}

Since you are using enumerate hence your i is actually the index of the key rather than the key itself.

So, you are getting 3 in the first column of the row 3 4even though there is no key 3.

enumerate iterates through a data structure(be it list or a dictionary) while also providing the current iteration number.

Hence, the columns here are the iteration number followed by the key in dictionary enum

Others Solutions have already shown how to iterate over key and value pair so I won't repeat the same in mine.

Two ways:

Use indexes:

double sum = 0;
for(int i = 0; i < m.size(); i++)
    sum += m.get(i);
return sum;

Use the "for each" style:

double sum = 0;
for(Double d : m)
    sum += d;
return sum;

Along the same lines as Gareth's answer, check out DefaultMutableTreeNode. It's not generic, but otherwise seems to fit the bill. Even though it's in the javax.swing package, it doesn't depend on any AWT or Swing classes. In fact, the source code actually has the comment // ISSUE: this class depends on nothing in AWT -- move to java.util?

You can use a plain old C array:

NSInteger myIntegers[40];

for (NSInteger i = 0; i < 40; i++)
    myIntegers[i] = i;

// to get one of them
NSLog (@"The 4th integer is: %d", myIntegers[3]);

Or, you can use an NSArray or NSMutableArray, but here you will need to wrap up each integer inside an NSNumber instance (because NSArray objects are designed to hold class instances).

NSMutableArray *myIntegers = [NSMutableArray array];

for (NSInteger i = 0; i < 40; i++)
    [myIntegers addObject:[NSNumber numberWithInteger:i]];

// to get one of them
NSLog (@"The 4th integer is: %@", [myIntegers objectAtIndex:3]);

// or
NSLog (@"The 4th integer is: %d", [[myIntegers objectAtIndex:3] integerValue]);

Had same issue, so if you're using angular2-cli with scss/sass use '/deep/' instead of '>>>', last selector isn't supported yet (but works great with css).

For anyone trying to

• "show text under marker on google maps", or
• "Google Maps Marker Label With Multiple Characters"

...in 2019, it's worth noting some of the code referenced here no longer exists (officially). Google discontinued support for the "MarkerWithLabel" project a long time ago. It was originally hosted on Google code here, now it's unofficially hosted on Github here.

But there is another project Google maintained until 2016, called "MapLabel"s. That approach is different (and arguably better). You create a separate map label object with the same origin as the marker instead of adding a mapLabel option to the marker itself. You can make a marker with label with multiple characters using js-marker-label.

pathinfo is cool but your code can be improved:

$filename = $_FILES['video_file']['name'];
$ext = pathinfo($filename, PATHINFO_EXTENSION);
$allowed = array('jpg','png','gif');
if( ! in_array( $ext, $allowed ) ) {echo 'error';}

Of course simply checking the extension of the filename would not guarantee the file type as a valid image. You may consider using a function like getimagesize to validate uploaded image files.

You could just use REPLACE:

UPDATE myTable SET emailCol = REPLACE(emailCol, '.com', '.org')`.

But take into account an email address such as [email protected] will be updated to [email protected].

If you want to be on a safer side, you should check for the last 4 characters using RIGHT, and append .org to the SUBSTRING manually instead. Notice the usage of UPPER to make the search for the .com ending case insensitive.

UPDATE myTable 
SET emailCol = SUBSTRING(emailCol, 1, LEN(emailCol)-4) + '.org'
WHERE UPPER(RIGHT(emailCol,4)) = '.COM';

See it working in this SQLFiddle.

Actually awk has a feature called 'Input Field Separator Variable' link. This is how to use it. It's not really an array, but it uses the internal $ variables. For splitting a simple string it is easier.

echo "12|23|11" | awk 'BEGIN {FS="|";} { print $1, $2, $3 }'

There is a much simpler way. Put your picture in a comment box within the description cell. That way you only have one column and when you sort the picture will always stay with the description. Okay... Right click the cell containing the description... Insert comment...right click the outer border... Format comment...colours and lines tab... Colour drop down...Fill effects...Picture tab...select picture...browse for your picture (it might be best to keep all pictures in one folder for ease of placement)...ok... you will probably need to go to the size tab and frig around with the height and width. Done... You now only need to mouse over the red in the top right corner of the cell and the picture will appear...like magic.

This method means that the row height can be kept to a minimum and the pictures can be as big as you like.

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

One more possibility to check. Listing here because it just happened to me and wasn't mentioned;-)

I had accidentally added a space character on the end of the name. Many hours of trying things before I finally noticed it. It's always something simple after you figure it out.

Here is a function that does the job quite well. I could not get the Best Answer above to work.

jQuery.extend({
    getValues: function(url) {
        var result = null;
        $.ajax({
            url: url,
            type: 'get',
            dataType: 'xml',
            async: false,
            success: function(data) {
                result = data;
            }
        });
       return result;
    }
});

Then to access it, create the variable like so:

var results = $.getValues("url string");

the only one that worked for me:

function goBackAndRefresh() {
  window.history.go(-1);
  setTimeout(() => {
    location.reload();
  }, 0);
}

Can I include GPL licensed code in a MIT licensed product?

You can. GPL is free software as well as MIT is, both licenses do not restrict you to bring together the code where as "include" is always two-way.

In copyright for a combined work (that is two or more works form together a work), it does not make much of a difference if the one work is "larger" than the other or not.

So if you include GPL licensed code in a MIT licensed product you will at the same time include a MIT licensed product in GPL licensed code as well.

As a second opinion, the OSI listed the following criteria (in more detail) for both licenses (MIT and GPL):

1. Free Redistribution
2. Source Code
3. Derived Works
4. Integrity of The Author's Source Code
5. No Discrimination Against Persons or Groups
6. No Discrimination Against Fields of Endeavor
7. Distribution of License
8. License Must Not Be Specific to a Product
9. License Must Not Restrict Other Software
10. License Must Be Technology-Neutral

Both allow the creation of combined works, which is what you've been asking for.

If combining the two works is considered being a derivate, then this is not restricted as well by both licenses.

And both licenses do not restrict to distribute the software.

It seems to me that the chief difference between the MIT license and GPL is that the MIT doesn't require modifications be open sourced whereas the GPL does.

The GPL doesn't require you to release your modifications only because you made them. That's not precise.

You might mix this with distribiution of software under GPL which is not what you've asked about directly.

Is that correct - is the GPL is more restrictive than the MIT license?

This is how I understand it:

As far as distribution counts, you need to put the whole package under GPL. MIT code inside of the package will still be available under MIT whereas the GPL applies to the package as a whole if not limited by higher rights.

"Restrictive" or "more restrictive" / "less restrictive" depends a lot on the point of view. For a software-user the MIT might result in software that is more restricted than the one available under GPL even some call the GPL more restrictive nowadays. That user in specific will call the MIT more restrictive. It's just subjective to say so and different people will give you different answers to that.

As it's just subjective to talk about restrictions of different licenses, you should think about what you would like to achieve instead:

• If you want to restrict the use of your modifications, then MIT is able to be more restrictive than the GPL for distribution and that might be what you're looking for.
• In case you want to ensure that the freedom of your software does not get restricted that much by the users you distribute it to, then you might want to release under GPL instead of MIT.

As long as you're the author it's you who can decide.

So the most restrictive person ever is the author, regardless of which license anybody is opting for ;)

That looks like the GitLab issue 5769.

In GitLab, since the repositories always end in .git, I must specify .git at the end of the repository name to make it work, for example:

import "example.org/myuser/mygorepo.git"

And:

$ go get example.org/myuser/mygorepo.git

Looks like GitHub solves this by appending ".git".

It is supposed to be resolved in “Added support for Go's repository retrieval. #5958”, provided the right meta tags are in place.
Although there is still an issue for Go itself: “cmd/go: go get cannot discover meta tag in HTML5 documents”.

Some other options if you do not want your own "Utils"-class:

Use Apache commons lang (ArrayUtils):

@Test
public void arrayCommonLang(){
    char[] test = {'h', 'e', 'l', 'l', 'o'};
    Assert.assertTrue(ArrayUtils.contains(test, 'o'));
    Assert.assertFalse(ArrayUtils.contains(test, 'p'));
}

Or use the builtin Arrays:

@Test
public void arrayTest(){
    char[] test = {'h', 'e', 'l', 'l', 'o'};
    Assert.assertTrue(Arrays.binarySearch(test, 'o') >= 0);
    Assert.assertTrue(Arrays.binarySearch(test, 'p') < 0);
}

Or use the Chars class from Google Guava:

@Test
public void testGuava(){
    char[] test = {'h', 'e', 'l', 'l', 'o'};
    Assert.assertTrue(Chars.contains(test, 'o'));
    Assert.assertFalse(Chars.contains(test, 'p'));
}

Slightly off-topic, the Chars class allows to find a subarray in an array.

What you need are character classes. In that, you've only to worry about the ], \ and - characters (and ^ if you're placing it straight after the beginning of the character class "[" ).

Syntax: [characters] where characters is a list with characters.

Example:

var cleanString = dirtyString.replace(/[|&;$%@"<>()+,]/g, "");

Might very well be the Console.ReadLine blocking your callback's Console.Writeline, in fact. The sample on MSDN looks ALMOST identical, except they use ReadKey (which doesn't lock the console).

You can import a csv file to this website(https://www.tablesgenerator.com/latex_tables) and click copy to clipboard.

You could try an XPath expression like:

'//div[contains(text(), "{0}") and @class="inner"]'.format(text)

The keyword for Oracle PL/SQL is "ELSIF" ( no extra "E"), not ELSEIF (yes, confusing and stupid)

declare
    var_number number;
begin
    var_number := 10;
    if var_number > 100 then
       dbms_output.put_line(var_number||' is greater than 100');
    elsif var_number < 100 then
       dbms_output.put_line(var_number||' is less than 100');
    else
       dbms_output.put_line(var_number||' is equal to 100');
    end if;
end;

Based on other answers and my tries, best experience would be first installing, pillow and scipy, then using the following starting code on your jupyter notebook:

%matplotlib inline
from matplotlib.pyplot import imshow
from scipy.misc import imread

imshow(imread('image.jpg', 1))

You can not alter constraints ever but you can drop them and then recreate.

Have look on this

ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;

and then recreate it with ON DELETE CASCADE like this

ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
    ON DELETE CASCADE;

hope this help

Before proceeding:

• Install a proper mergetool. On Linux, I strongly suggest you to use meld:

  sudo apt-get install meld
  

• Configure your mergetool:

  git config --global merge.tool meld
  

Then, iterate in the following way:

git cherry-pick ....
git mergetool
git cherry-pick --continue

A bit more detail to Joachim Sauer's answer:

On Ubuntu at least, the metapackage tomcat6 depends on metapackage tomcat6-common (and others), which depends on metapackage libtomcat6-java, which depends on package libservlet2.5-java (and others). It contains, among others, the files /usr/share/java/servlet-api-2.5.jar and /usr/share/java/jsp-api-2.1.jar, which are the servlet and JSP libraries you need. So if you've installed Tomcat 6 through apt-get or the Ubuntu Software Centre, you already have the libraries; all that's left is to get Tomcat to use them in your project.

Place libraries /usr/share/java/servlet-api-2.5.jar and /usr/share/java/jsp-api-2.1.jar on the class path like this:

• For all projects, by configuring Eclipse by selecting Window -> Preferences -> Java -> Installed JREs, then selecting the JRE you're using, pressing Edit, then pressing Add External JARs, and then by selecting the files from the locations given above.

• For just one project, by right-clicking on the project in the Project Explorer pane, then selecting Properties -> Java Build Path, and then pressing Add External JARs, and then by selecting the files from the locations given above.

Further note 1: These are the correct versions of those libraries for use with Tomcat 6; for the other Tomcat versions, see the table on page http://tomcat.apache.org/whichversion.html, though I would suppose each Tomcat version includes the versions of these libraries that are appropriate for it.

Further note 2: Package libservlet2.5-java's description (dpkg-query -s libservlet2.5-java) says: 'Apache Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a "pure Java" HTTP web server environment for Java code to run. This package contains the Java Servlet and JSP library.'

Form the Inheritance concept, If some perticular method is not available in the current class it will search for that method in super classes. If available it executes.

It executes AbstractList<E> class add() method which throws UnsupportedOperationException.

When you are converting from an Array to a Collection Obejct. i.e., array-based to collection-based API then it is going to provide you fixed-size collection object, because Array's behaviour is of Fixed size.

java.util.Arrays.asList( T... a )

Souce samples for conformation.

public class Arrays {
    public static <T> List<T> asList(T... a) {
        return new java.util.Arrays.ArrayList.ArrayList<>(a); // Arrays Inner Class ArrayList
    }
    //...
    private static class ArrayList<E> extends AbstractList<E> implements RandomAccess, java.io.Serializable {
        //...
    }
}
public abstract class AbstractList<E> extends AbstractCollection<E> implements List<E> {
    public void add(int index, E element) {
        throw new UnsupportedOperationException();
    }
    public E set(int index, E element) {
        throw new UnsupportedOperationException();
    }
    public E remove(int index) {
        throw new UnsupportedOperationException();
    }

    public Iterator<E> iterator() {
        return new Itr();
    }
    private class Itr implements Iterator<E> {
        //...
    }

    public ListIterator<E> listIterator() {
        return listIterator(0);
    }
    private class ListItr extends Itr implements ListIterator<E> {
        //...
    }
}

Form the above Source you may observe that java.util.Arrays.ArrayList class doesn't @Override add(index, element), set(index, element), remove(index). So, From inheritance it executes super AbstractList<E> class add() function which throws UnsupportedOperationException.

As AbstractList<E> is an abstract class it provides the implementation to iterator() and listIterator(). So, that we can iterate over the list object.

List<String> list_of_Arrays = Arrays.asList(new String[] { "a", "b" ,"c"});

try {
    list_of_Arrays.add("Yashwanth.M");
} catch(java.lang.UnsupportedOperationException e) {
    System.out.println("List Interface executes AbstractList add() fucntion which throws UnsupportedOperationException.");
}
System.out.println("Arrays ? List : " + list_of_Arrays);

Iterator<String> iterator = list_of_Arrays.iterator();
while (iterator.hasNext()) System.out.println("Iteration : " + iterator.next() );

ListIterator<String> listIterator = list_of_Arrays.listIterator();
while (listIterator.hasNext())    System.out.println("Forward  iteration : " + listIterator.next() );
while(listIterator.hasPrevious()) System.out.println("Backward iteration : " + listIterator.previous());

You can even create Fixed-Size array form Collections class Collections.unmodifiableList(list);

Sample Source:

public class Collections {
    public static <T> List<T> unmodifiableList(List<? extends T> list) {
        return (list instanceof RandomAccess ?
                new UnmodifiableRandomAccessList<>(list) :
                new UnmodifiableList<>(list));
    }
}

A Collection — sometimes called a container — is simply an object that groups multiple elements into a single unit. Collections are used to store, retrieve, manipulate, and communicate aggregate data.

• HashMap vs HashTable
• Object Serialization uses the Serializable and Externalizable interfaces

I like these two because they seem the most logical, the latter being shorter and probably fastest (shown here using set literal syntax which has been backported to Python 2.7):

all(x in {'a', 'b', 'c'} for x in ['a', 'b'])
#   or
{'a', 'b'}.issubset({'a', 'b', 'c'})

May be you are missing Third party library to like actionBarSherlock, slidingMenu, achartengine Add it into lib folder and Add to Build Path..

Its work for me.

The configuration could be made as follows:

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcAutoConfigurationAdapter {

// specific project configuration

}

Important here is that your WebMvcConfig may override addResourceHandlers method and therefore you need to explicitly invoke super.addResourceHandlers(registry) (it is true that if you are satisfied with the default resource locations you don't need to override any method).

Another thing that needs to be commented here is that those default resource locations (/static, /public, /resources and /META-INF/resources) will be registered only if there isn't already a resource handler mapped to /**.

From this moment on, if you have an image on src/main/resources/static/images named image.jpg for instance, you can access it using the following URL: http://localhost:8080/images/image.jpg (being the server started on port 8080 and application deployed to root context).

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

I use #3. Same for long lists, tuples, etc. It doesn't require adding any extra spaces beyond the indentations. As always, be consistent.

mydict = {
    "key1": 1,
    "key2": 2,
    "key3": 3,
}

mylist = [
    (1, 'hello'),
    (2, 'world'),
]

nested = {
    a: [
        (1, 'a'),
        (2, 'b'),
    ],
    b: [
        (3, 'c'),
        (4, 'd'),
    ],
}

Similarly, here's my preferred way of including large strings without introducing any whitespace (like you'd get if you used triple-quoted multi-line strings):

data = (
    "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAABG"
    "l0RVh0U29mdHdhcmUAQWRvYmUgSW1hZ2VSZWFkeXHJZTwAAAEN"
    "xBRpFYmctaKCfwrBSCrRLuL3iEW6+EEUG8XvIVjYWNgJdhFjIX"
    "rz6pKtPB5e5rmq7tmxk+hqO34e1or0yXTGrj9sXGs1Ib73efh1"
    "AAAABJRU5ErkJggg=="
)

Give the optional argument a default value.

function date ($format, $timestamp='') {
}

XSLT 2.0 has upper-case() and lower-case() functions. In case of XSLT 1.0, you can use translate():

<xsl:value-of select="translate("xslt", "abcdefghijklmnopqrstuvwxyz", "ABCDEFGHIJKLMNOPQRSTUVWXYZ")" />

A cookie is a object with key value pair to store information related to the customer. Main objective is to personalize the customer's experience.

An utility method can be created like

private Cookie createCookie(String cookieName, String cookieValue) {
    Cookie cookie = new Cookie(cookieName, cookieValue);
    cookie.setPath("/");
    cookie.setMaxAge(MAX_AGE_SECONDS);
    cookie.setHttpOnly(true);
    cookie.setSecure(true);
    return cookie;
}

If storing important information then we should alsways put setHttpOnly so that the cookie cannot be accessed/modified via javascript. setSecure is applicable if you are want cookies to be accessed only over https protocol.

using above utility method you can add cookies to response as

Cookie cookie = createCookie("name","value");
response.addCookie(cookie);

In my case,

I realized that remote debugging runs and consumes most of the resources. I did not really need to make the app 64 bit so after forcing it to be 32 Bit, remote debugging did not run and the execution was faster.

If you're using PhpMyAdmin, you can now:

1. Select the database.
2. Click the "Operations" tab.
3. Under "Collation" section, select the desired collation.
4. Click the "Change all tables collations" checkbox.
5. A new "Change all tables columns collations" checkbox will appear.
6. Click the "Change all tables columns collations" checkbox.
7. Click the "Go" button.

I had over 250 tables to convert. It took a little over 5 minutes.

Shift + Insert usually works throughout X11.

This is how you do it

SELECT ID,NAME, (C_COUNTS+F_COUNTS) AS SUM_COUNTS 
FROM TABLE 
ORDER BY SUM_COUNTS LIMIT 20

The SUM function will add up all rows, so the order by clause is useless, instead you will have to use the group by clause.

I wrote this a long time ago (from years 1985-1992, with just a few tweaks since then), and just copy and paste the bits needed into each project.

You must call cfmakeraw on a tty obtained from tcgetattr. You cannot zero-out a struct termios, configure it, and then set the tty with tcsetattr. If you use the zero-out method, then you will experience unexplained intermittent failures, especially on the BSDs and OS X. "Unexplained intermittent failures" include hanging in read(3).

The values for speed are B115200, B230400, B9600, B19200, B38400, B57600, B1200, B2400, B4800, etc. The values for parity are 0 (meaning no parity), PARENB|PARODD (enable parity and use odd), PARENB (enable parity and use even), PARENB|PARODD|CMSPAR (mark parity), and PARENB|CMSPAR (space parity).

"Blocking" sets whether a read() on the port waits for the specified number of characters to arrive. Setting no blocking means that a read() returns however many characters are available without waiting for more, up to the buffer limit.

Addendum:

CMSPAR is needed only for choosing mark and space parity, which is uncommon. For most applications, it can be omitted. My header file /usr/include/bits/termios.h enables definition of CMSPAR only if the preprocessor symbol __USE_MISC is defined. That definition occurs (in features.h) with

#if defined _BSD_SOURCE || defined _SVID_SOURCE
 #define __USE_MISC     1
#endif

The introductory comments of <features.h> says:

/* These are defined by the user (or the compiler)
   to specify the desired environment:

...
   _BSD_SOURCE          ISO C, POSIX, and 4.3BSD things.
   _SVID_SOURCE         ISO C, POSIX, and SVID things.

It's a bit late, but use the ODBC "curdate" function (angle brackes 'fn' is the ODBC function escape sequence).

SELECT {fn curdate()}

While the answers above are valid, if you are iterating over a dict {key:value} it this is the approach I like to use:

for key, value in Dictionary.items():
    print(key, value)

Therefore, if I wanted to do something like stringify all keys and values in my dictionary, I would do this:

stringified_dictionary = {}
for key, value in Dictionary.items():
    stringified_dictionary.update({str(key): str(value)})
return stringified_dictionary

This avoids any mutation issues when applying this type of iteration, which can cause erratic behavior (sometimes) in my experience.

var dateToday = new Date();

$('#datepicker').datepicker({                                     
    'startDate': dateToday
});

While jball's answer is an excellent description of content insets, it doesn't answer the question of when to use it. I'll borrow from his diagrams:

  _|?_cW_?_|_?_
   |       | 
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
   |content|    
-------------?-

That's what you get when you do it, but the usefulness of it only shows when you scroll:

  _|?_cW_?_|_?_
   |content| ? content is still visible
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
  _|_______|___ 
             ?

That top row of content will still be visible because it's still inside the frame of the scroll view. One way to think of the top offset is "how much to shift the content down the scroll view when we're scrolled all the way to the top"

To see a place where this is actually used, look at the build-in Photos app on the iphone. The Navigation bar and status bar are transparent, and the contents of the scroll view are visible underneath. That's because the scroll view's frame extends out that far. But if it wasn't for the content inset, you would never be able to have the top of the content clear that transparent navigation bar when you go all the way to the top.

That is how I did it and it worked exactly as you asked for inside a RelativeLayout:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relativelayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/myImageSouce" />

    <TextView
        android:id="@+id/myImageViewText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@id/myImageView"
        android:layout_alignTop="@id/myImageView"
        android:layout_alignRight="@id/myImageView"
        android:layout_alignBottom="@id/myImageView"
        android:layout_margin="1dp"
        android:gravity="center"
        android:text="Hello"
        android:textColor="#000000" />

</RelativeLayout>

i saw this error when i was trying to send a form, and in one of the fields' names, i let the word "endereço".

echo form_input(array('class' => 'form-control', 'name' => 'endereco', 'placeholder' => 'Endereço', 'value' => set_value('endereco')));

When i changed 'ç' for 'c', the error was gone.

You just need the jQuery UI effects-core (13KB), to enable the duration of the adding (just like Omar Tariq it pointed out)

A great real-world example of where lazy loading comes in handy is with ORM's (Object Relation Mappers) such as Entity Framework and NHibernate.

Say you have an entity Customer which has properties for Name, PhoneNumber, and Orders. Name and PhoneNumber are regular strings but Orders is a navigation property that returns a list of every order the customer ever made.

You often might want to go through all your customer's and get their name and phone number to call them. This is a very quick and simple task, but imagine if each time you created a customer it automatically went and did a complex join to return thousands of orders. The worst part is that you aren't even going to use the orders so it is a complete waste of resources!

This is the perfect place for lazy loading because if the Order property is lazy it will not go fetch all the customer's order unless you actually need them. You can enumerate the Customer objects getting only their Name and Phone Number while the Order property is patiently sleeping, ready for when you need it.

If this is an attempt to use one GET action for several views that POST to several actions with different models, then try add a GET action for each POST action that redirects to the first GET to prevent 404 on refresh.

Long shot but common scenario.

echo produces a trailing newline character which is hashed too. Try:

/bin/echo -n foobar | sha256sum 

Try:

$result = curl_exec($cURL);
$result = json_decode($result,true);

Now you can access MessageID from $result['MessageID'].

As for the database, it's simply using a query like so:

INSERT INTO `tableName`(`Cancelled`,`Queued`,`SMSError`,`SMSIncommingMessage`,`Sent`,`SentDateTime`) VALUES('?','?','?','?','?');

Prepared.

Siamore, I keep seeing everyone using the command line to compile programs. I use x11 terminal from ide via code::blocks, a gnu gcc compiler on my linux box. I have never compiled a program from command line. So Siamore, if I want the programs name to be cp, do I initialize argv[0]="cp"; Cp being a string literal. And anything going to stdout goes on the command line??? The example you gave me Siamore I understood! Even though the string you entered was a few words long, it was still only one arg. Because it was encased in double quotations. So arg[0], the prog name, is actually your string literal with a new line character?? So I understand why you use if(argc!=3) print error. Because the prog name = argv[0] and there are 2 more args after that, and anymore an error has occured. What other reason would I use that? I really think that my lack of understanding about how to compile from the command line or terminal is my reason for lack understanding in this area!! Siamore, you have helped me understand cla's much better! Still don't fully understand but I am not oblivious to the concept. I'm gonna learn to compile from the terminal then re-read what you wrote. I bet, then I will fully understand! With a little more help from you lol

<> Code that I have not written myself, but from my book.

#include <stdio.h>

int main(int argc, char *argv[])
{
    int i;

    printf("The following arguments were passed to main(): ");
    for(i=1; i<argc; i++) printf("%s ", argv[i]);
    printf("\n");

    return 0;
} 

This is the output:

anthony@anthony:~\Documents/C_Programming/CLA$ ./CLA hey man
The follow arguments were passed to main(): hey man
anthony@anthony:~\Documents/C_Programming/CLA$ ./CLA hi how are you doing?
The follow arguments were passed to main(): hi how are you doing?

So argv is a table of string literals, and argc is the number of them. Now argv[0] is the name of the program. So if I type ./CLA to run the program ./CLA is argv[0]. The above program sets the command line to take an infinite amount of arguments. I can set them to only take 3 or 4 if I wanted. Like one or your examples showed, Siamore... if(argc!=3) printf("Some error goes here"); Thank you Siamore, couldn't have done it without you! thanks to the rest of the post for their time and effort also!

PS in case there is a problem like this in the future...you never know lol the problem was because I was using the IDE AKA Code::Blocks. If I were to run that program above it would print the path/directory of the program. Example: ~/Documents/C/CLA.c it has to be ran from the terminal and compiled using the command line. gcc -o CLA main.c and you must be in the directory of the file.

Configure the maven-compiler-plugin to use the same character encoding that your source files are encoded in (e.g):

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
        <encoding>UTF-8</encoding>
    </configuration>
</plugin>

Many maven plugins will by default use the "project.build.sourceEncoding" property so setting this in your pom will cover most plugins.

<project>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>
...

However, I prefer setting the encoding in each plugin's configuration that supports it as I like to be explicit.

When your source code is compiled by the maven-compiler-plugin your source code files are read in by the compiler plugin using whatever encoding the compiler plugin is configured with. If your source files have a different encoding than the compiler plugin is using then it is possible that some characters may not exist in both encodings.

Many people prefer to set the encoding on their source files to UTF-8 so as to avoid this problem. To do this in Eclipse you can right click on a project and select Properties->Resource->Text File Encoding and change it to UTF-8. This will encode all your source files in UTF-8. (You should also explicitly configure the maven-compiler-plugin as mentioned above to use UTF-8 encoding.) With your source files and the compiler plugin both using the same encoding you shouldn't have any more unmappable characters during compilation.

Note, You can also set the file encoding globally in eclipse through Window->Preferences->General->Workspace->Text File Encoding. You can also set the encoding per file type through Window->Preferences->General->Content Types.

I found a solution. Please follow the following steps:

1. Right Click the My comp. Icon

2. Click Advanced Setting.

3. CLick Environment Variable. On the top part of Environment Variable Click New

4. Set Variable name as: PATH then Set Variable Value as: (" the location of g++ .exe" ) For ex. C:\Program Files (x86)\Dev-Cpp\MinGW64\bin

5. Click OK

In your onTestClick function, pass in the event argument and call preventDefault() on it.

function onTestClick(e) {
    e.preventDefault();
}

No one said, but array_push only pushes a element to the END OF THE ARRAY, where $array[index] can insert a value at any given index. Big difference.

Android-M ie, API 23 introduced Runtime Permissions for reducing security flaws in android device, where users can now directly manage app permissions at runtime.so if the user denies a particular permission of your application you have to obtain it by asking the permission dialog that you mentioned in your query.

So check before action ie, check you have permission to access the resource link and if your application doesn't have that particular permission you can request the permission link and handle the the permissions request response like below.

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.

               } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

So finally, It's a good practice to go through behavior changes if you are planning to work with new versions to avoid force closes :)

Permissions Best Practices.

You can go through the official sample app here.

I just went through the same problem. And found out once you have a syntax or any type of error in you javascript, the whole file don't get loaded so you cannot use any of the other functions at all.

First declare a object of DecimalFormat class. Note the argument inside the DecimalFormat is #.00 which means exactly 2 decimal places of rounding off.

private static DecimalFormat df2 = new DecimalFormat("#.00");

Now, apply the format to your double value:

double input = 32.123456;
System.out.println("double : " + df2.format(input)); // Output: 32.12

Note in case of double input = 32.1;

Then the output would be 32.10 and so on.

Get the Last Segment using RegEx

str.replace(/.*\/(\w+)\/?$/, '$1');

$1 means using the capturing group. using in RegEx (\w+) create the first group then the whole string replace with the capture group.

let str = 'http://mywebsite/folder/file';
let lastSegment = str.replace(/.*\/(\w+)\/?$/, '$1');
console.log(lastSegment);

Have a look at the following

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

your controller should have action method which would accept HttpPostedFileBase;

 public ActionResult FileUpload(HttpPostedFileBase file)
    {
        if (file != null)
        {
            string pic = System.IO.Path.GetFileName(file.FileName);
            string path = System.IO.Path.Combine(
                                   Server.MapPath("~/images/profile"), pic); 
            // file is uploaded
            file.SaveAs(path);

            // save the image path path to the database or you can send image 
            // directly to database
            // in-case if you want to store byte[] ie. for DB
            using (MemoryStream ms = new MemoryStream()) 
            {
                 file.InputStream.CopyTo(ms);
                 byte[] array = ms.GetBuffer();
            }

        }
        // after successfully uploading redirect the user
        return RedirectToAction("actionname", "controller name");
    }

Update 1

In case you want to upload files using jQuery with asynchornously, then try this article.

the code to handle the server side (for multiple upload) is;

 try
    {
        HttpFileCollection hfc = HttpContext.Current.Request.Files;
        string path = "/content/files/contact/";

        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            if (hpf.ContentLength > 0)
            {
                string fileName = "";
                if (Request.Browser.Browser == "IE")
                {
                    fileName = Path.GetFileName(hpf.FileName);
                }
                else
                {
                    fileName = hpf.FileName;
                }
                string fullPathWithFileName = path + fileName;
                hpf.SaveAs(Server.MapPath(fullPathWithFileName));
            }
        }

    }
    catch (Exception ex)
    {
        throw ex;
    }

this control also return image name (in a javascript call back) which then you can use it to display image in the DOM.

UPDATE 2

Alternatively, you can try Async File Uploads in MVC 4.

Other answers deal with the technical aspect of the border-opacity issue, while I'd like to present a hack(pure CSS and HTML only). Basically create a container div, having a border div and then the content div.

<div class="container">
  <div class="border-box"></div>
  <div class="content-box"></div>
</div>

And then the CSS:(set content border to none, take care of positioning such that border thickness is accounted for)

.container {
  width: 20vw;
  height: 20vw;
  position: relative;
}
.border-box {
  width: 100%;
  height: 100%;
  border: 5px solid black;
  position: absolute;
  opacity: 0.5;
}
.content-box {
  width: 100%;
  height: 100%;
  border: none;
  background: green;
  top: 5px;
  left: 5px;
  position: absolute;
}

You don't really need to have parenthesis. You can sort directly:

SELECT *, 1 AS RN FROM TABLE_A
UNION ALL 
SELECT *, 2 AS RN FROM TABLE_B
ORDER BY RN, COLUMN_1

close():- Suppose you have opened multiple browser windows with same driver instance, now calling close() on the driver instance will close the current window the driver instance is pointed to. But the driver instance still remain in memory and can be used to handle other open browser windows.

quit():- If you call quit() on the driver instance and there are one or more browser windows open, it will close all the open browser windows and the driver instance is garbage collected i.e. removed from the memory. So now you cannot use this driver instance to do other operation after calling quit() on it. If you do it will throw an Exception.

dispose():- I don't think there is a dispose method for a WebDriver instance.

You can go to the this selenium official java doc link for reference.

Because some database can throw an exception at dbContextTransaction.Commit() so better this:

using (var context = new BloggingContext()) 
{ 
  using (var dbContextTransaction = context.Database.BeginTransaction()) 
  { 
    try 
    { 
      context.Database.ExecuteSqlCommand( 
          @"UPDATE Blogs SET Rating = 5" + 
              " WHERE Name LIKE '%Entity Framework%'" 
          ); 

      var query = context.Posts.Where(p => p.Blog.Rating >= 5); 
      foreach (var post in query) 
      { 
          post.Title += "[Cool Blog]"; 
      } 

      context.SaveChanges(false); 

      dbContextTransaction.Commit(); 

      context.AcceptAllChanges();
    } 
    catch (Exception) 
    { 
      dbContextTransaction.Rollback(); 
    } 
  } 
} 

Never tried it, but git help ignore suggests that if you put a .gitignore with *.js in /public/static, it will do what you want.

Note: make sure to also check out Joeys' answer below: if you want to ignore files in a specific subdirectory, then a local .gitignore is the right solution (locality is good). However if you need the same pattern to apply to your whole repo, then the ** solution is better.

def _GetHtmlPage(self, addr):
  headers = { 'User-Agent' : self.userAgent,
            '  Cookie' : self.cookies}

  req = urllib2.Request(addr)
  response = urllib2.urlopen(req)

  print "ResponseInfo="
  print response.info()

  resultsHtml = unicode(response.read(), self.encoding)
  return resultsHtml  

A SELECT INTO statement creates the table for you. There is no need for the CREATE TABLE statement before hand.

What is happening is that you create #ivmy_cash_temp1 in your CREATE statement, then the DB tries to create it for you when you do a SELECT INTO. This causes an error as it is trying to create a table that you have already created.

Either eliminate the CREATE TABLE statement or alter your query that fills it to use INSERT INTO SELECT format.

If you need a unique ID added to your new row then it's best to use SELECT INTO... since IDENTITY() only works with this syntax.

You can use setattr

name  = 'varname'
value = 'something'

setattr(self, name, value) #equivalent to: self.varname= 'something'

print (self.varname)
#will print 'something'

But, since you should inform an object to receive the new variable, this only works inside classes or modules.

Use the keyword and, not & because & is a bit operator.

Be careful with this... just so you know, in Java and C++, the & operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&. Similarly | is a bit operator, and || is a boolean operator. In Python and and or are used for boolean comparisons.

Try:

my_command || { echo 'my_command failed' ; exit 1; }

Four changes:

• Change && to ||
• Use { } in place of ( )
• Introduce ; after exit and
• spaces after { and before }

Since you want to print the message and exit only when the command fails ( exits with non-zero value) you need a || not an &&.

cmd1 && cmd2

will run cmd2 when cmd1 succeeds(exit value 0). Where as

cmd1 || cmd2

will run cmd2 when cmd1 fails(exit value non-zero).

Using ( ) makes the command inside them run in a sub-shell and calling a exit from there causes you to exit the sub-shell and not your original shell, hence execution continues in your original shell.

To overcome this use { }

The last two changes are required by bash.

You could do it this way but it leaves it as a varchar

declare @s varchar(50)

set @s = '2011-09-28 18:01:00'

select convert(varchar, cast(@s as datetime), 105) + RIGHT(@s, 9)

or

select convert(varchar(20), @s, 105)

Simple: don't use an AsyncTask. AsyncTask is designed for short operations that end quickly (tens of seconds) and therefore do not need to be canceled. "Audio file playback" does not qualify. You don't even need a background thread for ordinary audio file playback.

I've found that one of our programmers added the following line to one of the imports:

os.chdir(<path_to_a_local_folder>)

This caused the Celery worker to change its working directory from the projects' default working directory (where it could find the tasks) to a different directory (where it couldn't find the tasks).

After removing this line of code, all tasks were found and registered.

Just put the

Response.End();

within a finally block instead of within the try block.

This has worked for me!!!.

I had the following problematic (with the Exception) code structure

...
Response.Clear();
...
...
try{
 if (something){
   Reponse.Write(...);
   Response.End();

   return;

 } 

 some_more_code...

 Reponse.Write(...);
 Response.End();

}
catch(Exception){
}
finally{}

and it throws the exception. I suspect the Exception is thrown where there is code / work to execute after response.End(); . In my case the extra code was just the return itself.

When I just moved the response.End(); to the finally block (and left the return in its place - which causes skipping the rest of code in the try block and jumping to the finally block (not just exiting the containing function) ) the Exception ceased to take place.

The following works OK:

...
Response.Clear();
...
...
try{
 if (something){
   Reponse.Write(...);

   return;

 } 

 some_more_code...

 Reponse.Write(...);

}
catch(Exception){
}
finally{
    Response.End();
}

Note : Use it if calculating / adding days from current date.

Be aware: this answer has issues (see comments)

var myDate = new Date();
myDate.setDate(myDate.getDate() + AddDaysHere);

It should be like

var newDate = new Date(date.setTime( date.getTime() + days * 86400000 ));

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

You can use Time::Piece, which shouldn't need installing as it is a core module and has been distributed with Perl 5 since version 10.

use Time::Piece;

my $date = localtime->strftime('%m/%d/%Y');
print $date;

output

06/13/2012

Update

You may prefer to use the dmy method, which takes a single parameter which is the separator to be used between the fields of the result, and avoids having to specify a full date/time format

my $date = localtime->dmy('/');

This produces an identical result to that of my original solution

As of R 3.2.0 a new function was introduced for removing leading/trailing white spaces:

trimws()

See: Remove Leading/Trailing Whitespace

If you don't need to initiate a post back when you press this button, then making the overhead of a server control isn't necesary.

<input id="addButton" type="button" value="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#addButton').click(function() 
         { 
             showDialog('#addPerson'); 
         });
     });
</script>

If you still need to be able to do a post back, you can conditionally stop the rest of the button actions with a little different code:

<asp:Button ID="buttonAdd" runat="server" Text="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#<%= buttonAdd.ClientID %>').click(function(e) 
         { 
             showDialog('#addPerson');

             if(/*Some Condition Is Not Met*/) 
                return false;
         });
     });
</script>

Use prepared statements. Those keep the data and syntax apart, which removes the need for escaping MySQL data. See e.g. this tutorial.
