I took hhafez code and added a memory test:
private static void test() {
Runtime runtime = Runtime.getRuntime();
long memory;
...
memory = runtime.freeMemory();
// for loop code
memory = memory-runtime.freeMemory();
I run this separately for each approach, the '+' operator, String.format and StringBuilder (calling toString()), so the memory used will not be affected by other approaches. I added more concatenations, making the string as "Blah" + i + "Blah"+ i +"Blah" + i + "Blah".
The result are as follow (average of 5 runs each):
Approach Time(ms) Memory allocated (long)
'+' operator 747 320,504
String.format 16484 373,312
StringBuilder 769 57,344
We can see that String '+' and StringBuilder are practically identical time-wise, but StringBuilder is much more efficient in memory use. This is very important when we have many log calls (or any other statements involving strings) in a time interval short enough so the Garbage Collector won't get to clean the many string instances resulting of the '+' operator.
And a note, BTW, don't forget to check the logging level before constructing the message.
Conclusions:
if you really wanted to do that you could then do
<script type="text/javascript">
document.write(produceMessage())
</script>
Wherever in the document you want the message.

I needed to convert a single column of strings of form nn.n% to float. I needed to remove the % from the element in each row. The attend data frame has two columns.
attend.iloc[:,1:2]=attend.iloc[:,1:2].applymap(lambda x: float(x[:-1]))
Its an extenstion to the original answer. In my case it takes a dataframe and applies a function to each value in a specific column. The function removes the last character and converts the remaining string to float.
Using Kotlin you can do something like:
import android.content.Context
import android.support.v4.content.ContextCompat
import android.support.v7.widget.CardView
import android.widget.*
import android.widget.LinearLayout
class RespondTo : CardView {
constructor(context: Context) : super(context) {
init(context)
}
private fun init(context: Context) {
val parent = LinearLayout(context)
parent.apply {
layoutParams = LinearLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.WRAP_CONTENT, 1.0f).apply {
orientation = LinearLayout.HORIZONTAL
addView(EditText(context).apply {
id = generateViewId()
layoutParams = LinearLayout.LayoutParams(0,
LinearLayout.LayoutParams.WRAP_CONTENT, 0.9f).apply {
}
})
addView(ImageButton(context).apply({
layoutParams = LinearLayout.LayoutParams(0,
LinearLayout.LayoutParams.WRAP_CONTENT, 0.1f)
background = null
setImageDrawable(ContextCompat.getDrawable(context, R.drawable.ic_save_black_24px))
id = generateViewId()
layoutParams = RelativeLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT).apply {
addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
// addRule(RelativeLayout.LEFT_OF, myImageButton.id)
}
}))
}
}
this.addView(parent)
}
}
Yes, there is: you can capture the echoed text using ob_start:
<?php function TestBlockHTML($replStr) {
ob_start(); ?>
<html>
<body><h1><?php echo($replStr) ?></h1>
</html>
<?php
return ob_get_clean();
} ?>
You should probably use the ngHref directive along with the ngClick:
<a ng-href='#here' ng-click='go()' >click me</a>
Here is an example: http://plnkr.co/edit/FSH0tP0YBFeGwjIhKBSx?p=preview
<body ng-controller="MainCtrl">
<p>Hello {{name}}!</p>
{{msg}}
<a ng-href='#here' ng-click='go()' >click me</a>
<div style='height:1000px'>
<a id='here'></a>
</div>
<h1>here</h1>
</body>
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.go = function() {
$scope.msg = 'clicked';
}
});
I don't know if this will work with the library you are using but it will at least let you link and use the ngClick function.
** Update **
Here is a demo of the set and get working fine with a service.
http://plnkr.co/edit/FSH0tP0YBFeGwjIhKBSx?p=preview
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope, sharedProperties) {
$scope.name = 'World';
$scope.go = function(item) {
sharedProperties.setListName(item);
}
$scope.getItem = function() {
$scope.msg = sharedProperties.getListName();
}
});
app.service('sharedProperties', function () {
var list_name = '';
return {
getListName: function() {
return list_name;
},
setListName: function(name) {
list_name = name;
}
};
});

Hej man, why are you using this ?
dir /s/b/o:gn > f.txt (wrong one)
Don't you know what is that 'g' in '/o' ??
Check this out: http://www.computerhope.com/dirhlp.htm or dir /? for dir help
You should be using this instead:
dir /s/b/o:n > f.txt (right one)
MongoDB has a simple web based administrative port at 28017 by default.
There is no HTTP access at the default port of 27017 (which is what the error message is trying to suggest). The default port is used for native driver access, not HTTP traffic.
To access MongoDB, you'll need to use a driver like the MongoDB native driver for NodeJS. You won't "POST" to MongoDB directly (but you might create a RESTful API using express which uses the native drivers). Instead, you'll use a wrapper library that makes accessing MongoDB convenient. You might also consider using Mongoose (which uses the native driver) which adds an ORM-like model for MongoDB in NodeJS.
If you can't get to the web interface, it may be disabled. Normally, I wouldn't expect that you'd need it for doing development unless you're checking logs and such.
Note that you can use other tricks like :
-- One or more wildcard:
.../Downloads20*/*.csv
-- braces and brackets
.../Downloads201[1-5]/book.csv
.../Downloads201{11,15,19,99}/book.csv
To get the Windows version number, as Jeff notes in his answer, use:
[Environment]::OSVersion
It is worth noting that the result is of type [System.Version], so it is possible to check for, say, Windows 7/Windows Server 2008 R2 and later with
[Environment]::OSVersion.Version -ge (new-object 'Version' 6,1)
However this will not tell you if it is client or server Windows, nor the name of the version.
Use WMI's Win32_OperatingSystem class (always single instance), for example:
(Get-WmiObject -class Win32_OperatingSystem).Caption
will return something like
Microsoft® Windows Server® 2008 Standard
import java.io.*;
import java.util.Scanner;
class ar1 {
public static void main(String[] args) {
//Scanner sc=new Scanner(System.in);
int[] a={10,20,30,40,12,32};
int bi=0,sm=0;
//bi=sc.nextInt();
//sm=sc.nextInt();
for(int i=0;i<=a.length-1;i++) {
if(a[i]>a[i+1])
bi=a[i];
if(a[i]<a[i+1])
sm=a[i];
}
System.out.println("big"+bi+"small"+sm);
}
}
I come a bit late with a more advanced version of Arun P Johny's answer. His solution doesn't handle multiple console.log() arguments and doesn't give an access to the original function.
Here's my version:
(function (logger) {_x000D_
console.old = console.log;_x000D_
console.log = function () {_x000D_
var output = "", arg, i;_x000D_
_x000D_
for (i = 0; i < arguments.length; i++) {_x000D_
arg = arguments[i];_x000D_
output += "<span class=\"log-" + (typeof arg) + "\">";_x000D_
_x000D_
if (_x000D_
typeof arg === "object" &&_x000D_
typeof JSON === "object" &&_x000D_
typeof JSON.stringify === "function"_x000D_
) {_x000D_
output += JSON.stringify(arg); _x000D_
} else {_x000D_
output += arg; _x000D_
}_x000D_
_x000D_
output += "</span> ";_x000D_
}_x000D_
_x000D_
logger.innerHTML += output + "<br>";_x000D_
console.old.apply(undefined, arguments);_x000D_
};_x000D_
})(document.getElementById("logger"));_x000D_
_x000D_
// Testing_x000D_
console.log("Hi!", {a:3, b:6}, 42, true);_x000D_
console.log("Multiple", "arguments", "here");_x000D_
console.log(null, undefined);_x000D_
console.old("Eyy, that's the old and boring one.");body {background: #333;}_x000D_
.log-boolean,_x000D_
.log-undefined {color: magenta;}_x000D_
.log-object,_x000D_
.log-string {color: orange;}_x000D_
.log-number {color: cyan;}<pre id="logger"></pre>I took it a tiny bit further and added a class to each log so you can color it. It outputs all arguments as seen in the Chrome console. You also have access to the old log via console.old().
Here's a minified version of the script above to paste inline, just for you:
<script>
!function(o){console.old=console.log,console.log=function(){var n,e,t="";for(e=0;e<arguments.length;e++)t+='<span class="log-'+typeof(n=arguments[e])+'">',"object"==typeof n&&"object"==typeof JSON&&"function"==typeof JSON.stringify?t+=JSON.stringify(n):t+=n,t+="</span> ";o.innerHTML+=t+"<br>",console.old.apply(void 0,arguments)}}
(document.body);
</script>
Replace document.body in the parentheses with whatever element you wish to log into.
I had a similar issue with zsh and nvm on Linux, I fixed it by adding nvm initialization script in ~/.profile and restart login session like this
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
You can implement non-blocking locks using compareAndSwap (CAS) on atomic integers or longs. The "Tl2" Software Transactional Memory paper describes this:
We associate a special versioned write-lock with every transacted memory location. In its simplest form, the versioned write-lock is a single word spinlock that uses a CAS operation to acquire the lock and a store to release it. Since one only needs a single bit to indicate that the lock is taken, we use the rest of the lock word to hold a version number.
What it is describing is first read the atomic integer. Split this up into an ignored lock-bit and the version number. Attempt to CAS write it as the lock-bit cleared with the current version number to the lock-bit set and the next version number. Loop until you succeed and your are the thread which owns the lock. Unlock by setting the current version number with the lock-bit cleared. The paper describes using the version numbers in the locks to coordinate that threads have a consistent set of reads when they write.
This article describes that processors have hardware support for compare and swap operations making the very efficient. It also claims:
non-blocking CAS-based counters using atomic variables have better performance than lock-based counters in low to moderate contention
completed = (id) => {
var details = {
'id': id,
};
var formBody = [];
for (var property in details) {
var encodedKey = encodeURIComponent(property);
var encodedValue = encodeURIComponent(details[property]);
formBody.push(encodedKey + "=" + encodedValue);
}
formBody = formBody.join("&");
fetch(markcompleted, {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/x-www-form-urlencoded'
},
body: formBody
})
.then((response) => response.json())
.then((responseJson) => {
console.log(responseJson, 'res JSON');
if (responseJson.status == "success") {
console.log(this.state);
alert("your todolist is completed!!");
}
})
.catch((error) => {
console.error(error);
});
};
You can use multiple id's the way you wrote:
$('#upload_link, #upload_link2, #upload_link3')
However, that doesn't mean that those ids exist within the DOM when you've executed your code. It also doesn't mean that upload is a legitimate function. It also doesn't mean that upload has been built in a way that allows for multiple elements in a selection.
upload is a custom jQuery plugin, so you'll have to show what's going on with upload for us to be able to help you.
To make it simple, setup.py is run as "__main__" when you call the install functions the other answers mentioned. Inside setup.py, you should put everything needed to install your package.
The following two sections discuss two things many setup.py modules have.
This function allows you to specify project attributes like the name of the project, the version.... Most importantly, this function allows you to install other functions if they're packaged properly. See this webpage for an example of setuptools.setup
These attributes of setuptools.setup enable installing these types of packages:
Packages that are imported to your project and listed in PyPI using setuptools.findpackages:
packages=find_packages(exclude=["docs","tests", ".gitignore", "README.rst","DESCRIPTION.rst"])
Packages not in PyPI, but can be downloaded from a URL using dependency_links
dependency_links=["http://peak.telecommunity.com/snapshots/",]
In an ideal world, setuptools.setup would handle everything for you. Unfortunately this isn't always the case. Sometimes you have to do specific things, like installing dependencies with the subprocess command, to get the system you're installing on in the right state for your package. Try to avoid this, these functions get confusing and often differ between OS and even distribution.
It normally means an un-aligned access.
An attempt to access memory that isn't physically present would also give a bus error, but you won't see this if you're using a processor with an MMU and an OS that's not buggy, because you won't have any non-existent memory mapped to your process's address space.
You have a variable that contains an address of something. That's a pointer.
Then you have another variable that contains the address of the first variable. That's a pointer to pointer.
if(str.isEmpty() || str.trim().length() == 0){
return 0;
}
return (str.trim().split("\\s+").length);
Update: This function only avoids copy if it can, hence this is not the correct answer for this question. unutbu's answer is the right one.
a = a.astype(numpy.float32, copy=False)
numpy astype has a copy flag. Why shouldn't we use it ?
For Tk-based backend (TkAgg), these two options maximize & fullscreen the window:
plt.get_current_fig_manager().window.state('zoomed')
plt.get_current_fig_manager().window.attributes('-fullscreen', True)
When plotting into multiple windows, you need to write this for each window:
data = rasterio.open(filepath)
blue, green, red, nir = data.read()
plt.figure(1)
plt.subplot(121); plt.imshow(blue);
plt.subplot(122); plt.imshow(red);
plt.get_current_fig_manager().window.state('zoomed')
rgb = np.dstack((red, green, blue))
nrg = np.dstack((nir, red, green))
plt.figure(2)
plt.subplot(121); plt.imshow(rgb);
plt.subplot(122); plt.imshow(nrg);
plt.get_current_fig_manager().window.state('zoomed')
plt.show()
Here, both 'figures' are plotted in separate windows. Using a variable such as
figure_manager = plt.get_current_fig_manager()
might not maximize the second window, since the variable still refers to the first window.

Ok so here is the working code when Using MVC and you are getting your file from a controller
lets say you have your byte array declare and populate, the only thing you need to do is to use the File function (using System.Web.Mvc)
byte[] bytes = .... insert your bytes in the array
return File(bytes, System.Net.Mime.MediaTypeNames.Application.Octet, "nameoffile.exe");
and then, in the same controller, add thoses 2 functions
protected override void OnResultExecuting(ResultExecutingContext context)
{
CheckAndHandleFileResult(context);
base.OnResultExecuting(context);
}
private const string FILE_DOWNLOAD_COOKIE_NAME = "fileDownload";
/// <summary>
/// If the current response is a FileResult (an MVC base class for files) then write a
/// cookie to inform jquery.fileDownload that a successful file download has occured
/// </summary>
/// <param name="context"></param>
private void CheckAndHandleFileResult(ResultExecutingContext context)
{
if (context.Result is FileResult)
//jquery.fileDownload uses this cookie to determine that a file download has completed successfully
Response.SetCookie(new HttpCookie(FILE_DOWNLOAD_COOKIE_NAME, "true") { Path = "/" });
else
//ensure that the cookie is removed in case someone did a file download without using jquery.fileDownload
if (Request.Cookies[FILE_DOWNLOAD_COOKIE_NAME] != null)
Response.Cookies[FILE_DOWNLOAD_COOKIE_NAME].Expires = DateTime.Now.AddYears(-1);
}
and then you will be able to call your controller to download and get the "success" or "failure" callback
$.fileDownload(mvcUrl('name of the controller'), {
httpMethod: 'POST',
successCallback: function (url) {
//insert success code
},
failCallback: function (html, url) {
//insert fail code
}
});
For the conversion to get the hexadecimal values in SQL back into ASCII, here is the solution I got on this (using the function from user chaos to encode into hexadecimal)
function hexEncode($data) {
if(is_numeric($data))
return $data;
$unpacked = unpack('H*hex', $data);
return '0x' . $unpacked['hex'];
}
function hexDecode($hex) {
$str = '';
for ($i=0; $i<strlen($hex); $i += 2)
$str .= chr(hexdec(substr($hex, $i, 2)));
return $str;
}
$stringHex = hexEncode('Test String');
var_dump($stringHex);
$stringAscii = hexDecode($stringHex);
var_dump($stringAscii);
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.
Did you forget to join some tables? If not then you probably need to use some aliases.
Activity code, its important to extend ListActivity.
package com.example.mylistactivity;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import com.example.mylistactivity.R;
// It's important to extend ListActivity rather than Activity
public class MyListActivity extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylist);
// shows list view
String[] values = new String[] { "foo", "bar" };
// shows empty view
values = new String[] { };
setListAdapter(new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
android.R.id.text1,
values));
}
}
Layout xml, the id in both views are important.

function hello(){_x000D_
console.log("hello")_x000D_
}_x000D_
$('#event-on-keyup').keyup(function(){_x000D_

})<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js"></script>_x000D_
<input type="text" id="event-on-keyup">I think the fastest way—without using lookup tables and popcount—is the following. It counts the set bits with just 12 operations.
int popcount(int v) {
v = v - ((v >> 1) & 0x55555555); // put count of each 2 bits into those 2 bits
v = (v & 0x33333333) + ((v >> 2) & 0x33333333); // put count of each 4 bits into those 4 bits
return c = ((v + (v >> 4) & 0xF0F0F0F) * 0x1010101) >> 24;
}
It works because you can count the total number of set bits by dividing in two halves, counting the number of set bits in both halves and then adding them up. Also know as Divide and Conquer paradigm. Let's get into detail..
v = v - ((v >> 1) & 0x55555555);
The number of bits in two bits can be 0b00, 0b01 or 0b10. Lets try to work this out on 2 bits..
---------------------------------------------
| v | (v >> 1) & 0b0101 | v - x |
---------------------------------------------
0b00 0b00 0b00
0b01 0b00 0b01
0b10 0b01 0b01
0b11 0b01 0b10
This is what was required: the last column shows the count of set bits in every two bit pair. If the two bit number is >= 2 (0b10) then and produces 0b01, else it produces 0b00.
v = (v & 0x33333333) + ((v >> 2) & 0x33333333);
This statement should be easy to understand. After the first operation we have the count of set bits in every two bits, now we sum up that count in every 4 bits.
v & 0b00110011 //masks out even two bits
(v >> 2) & 0b00110011 // masks out odd two bits
We then sum up the above result, giving us the total count of set bits in 4 bits. The last statement is the most tricky.
c = ((v + (v >> 4) & 0xF0F0F0F) * 0x1010101) >> 24;
Let's break it down further...
v + (v >> 4)
It's similar to the second statement; we are counting the set bits in groups of 4 instead. We know—because of our previous operations—that every nibble has the count of set bits in it. Let's look an example. Suppose we have the byte 0b01000010. It means the first nibble has its 4bits set and the second one has its 2bits set. Now we add those nibbles together.
0b01000010 + 0b01000000
It gives us the count of set bits in a byte, in the first nibble 0b01100010 and therefore we mask the last four bytes of all the bytes in the number (discarding them).
0b01100010 & 0xF0 = 0b01100000
Now every byte has the count of set bits in it. We need to add them up all together. The trick is to multiply the result by 0b10101010 which has an interesting property. If our number has four bytes, A B C D, it will result in a new number with these bytes A+B+C+D B+C+D C+D D. A 4 byte number can have maximum of 32 bits set, which can be represented as 0b00100000.
All we need now is the first byte which has the sum of all set bits in all the bytes, and we get it by >> 24. This algorithm was designed for 32 bit words but can be easily modified for 64 bit words.

size_t is an unsigned type that can hold maximum integer value for your architecture, so it is protected from integer overflows due to sign (signed int 0x7FFFFFFF incremented by 1 will give you -1) or short size (unsigned short int 0xFFFF incremented by 1 will give you 0).
It is mainly used in array indexing/loops/address arithmetic and so on. Functions like memset() and alike accept size_t only, because theoretically you may have a block of memory of size 2^32-1 (on 32bit platform).
For such simple loops don't bother and use just int.
So what I did was to have the standard src/main/resources/application.properties and also a src/test/resources/application-default.properties where i override some settings for ALL my tests.
I ran into the same problem and was not using profiles either so far. It seemed to be bothersome to have to do it now and remember declaring the profile -- which can be easily forgotten.
The trick is, to leverage that a profile specific application-<profile>.properties overrides settings in the general profile. See https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-config-profile-specific-properties.
It should be
yadayada.val.split(/\n/)
you're passing in a literal string to the split command, not a regex.
might be surprised to know.. its PHP. read all about it here
string = "{'server1':'value','server2':'value'}"
#Now removing { and }
s = string.replace("{" ,"")
finalstring = s.replace("}" , "")
#Splitting the string based on , we get key value pairs
list = finalstring.split(",")
dictionary ={}
for i in list:
#Get Key Value pairs separately to store in dictionary
keyvalue = i.split(":")
#Replacing the single quotes in the leading.
m= keyvalue[0].strip('\'')
m = m.replace("\"", "")
dictionary[m] = keyvalue[1].strip('"\'')
print dictionary
This comment on this page worked for me and a few others. It deserves its own answer:
python manage.py migrate --run-syncdb
By mistake I added the compile com.google.android.gms:play-services:5.+ in dependencies in build script block. You should add it in the second dependency block. make changes->synch project with gradle.
I had the same problem, and I have solved it with the module line-by-line
https://www.npmjs.com/package/line-by-line
At least for me works like a charm, both in synchronous and asynchronous mode.
Also, the problem with lines terminating not terminating \n can be solved with the option:
{ encoding: 'utf8', skipEmptyLines: false }
Synchronous processing of lines:
var LineByLineReader = require('line-by-line'),
lr = new LineByLineReader('big_file.txt');
lr.on('error', function (err) {
// 'err' contains error object
});
lr.on('line', function (line) {
// 'line' contains the current line without the trailing newline character.
});
lr.on('end', function () {
// All lines are read, file is closed now.
});
I would use a value that gets set when more button get pushed closed the first dialog and then have the original form test the value and then display the the there dialog.
For the Ex
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private bool DrawText = false;
private void button1_Click(object sender, EventArgs e)
{
Form2 f2 = new Form2();
f2.ShowDialog();
if (f2.ShowMoreActions)
{
Form3 f3 = new Form3();
f3.ShowDialog();
}
}
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
public bool ShowMoreActions = false;

Use this for GET values:
Request.QueryString["key"]
And this for POST values
Request.Form["key"]
Also, this will work if you don't care whether it comes from GET or POST, or the HttpContext.Items collection:
Request["key"]
Another thing to note (if you need it) is you can check the type of request by using:
Request.RequestType
Which will be the verb used to access the page (usually GET or POST). Request.IsPostBack will usually work to check this, but only if the POST request includes the hidden fields added to the page by the ASP.NET framework.
DisplayName sets the DisplayName in the model metadata. For example:
[DisplayName("foo")]
public string MyProperty { get; set; }
and if you use in your view the following:
@Html.LabelFor(x => x.MyProperty)
it would generate:
<label for="MyProperty">foo</label>
Display does the same, but also allows you to set other metadata properties such as Name, Description, ...
Brad Wilson has a nice blog post covering those attributes.
If you are still getting that error after installing the 64 bit JRE, it means that the JVM running Gurobi package is still using the 32 bit JRE.
Check that you have updated the PATH and JAVA_HOME globally and in the command shell that you are using. (Maybe you just need to exit and restart it.)
Check that your command shell runs the right version of Java by running "java -version" and checking that it says it is a 64bit JRE.
If you are launching the example via a wrapper script / batch file, make sure that the script is using the right JRE. Modify as required ...
I would recommend to use this since I have the same issue which got fixed.
$('input:text').focus(
function(){
$(this).val('');

You forgot to put z as an bind variable.
The following EXECUTE command runs a PL/SQL statement that references a stored procedure:
SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')
Note that the value returned by the stored procedure is being return into :Z

You cannot format a nullable DateTime - you have to use the DateTime.Value property.
@Model.AuditDate.HasValue ? Model.AuditDate.Value.ToString("mm/dd/yyyy") : string.Empty
Tip: It is always helpful to work this stuff out in a standard class with intellisense before putting it into a view. In this case, you would get a compile error which would be easy to spot in a class.
Your selector is retrieving the text box's surrounding <div class='textBoxEmployeeNumber'> instead of the input inside it.
// Access the input inside the div with this selector:
$(function () {
$('.textBoxEmployeeNumber input').val("fgg");
});
If the ASP.NET code reliably outputs the HTML <input> with an id attribute id='EmployeeId', you can more simply just use:
$(function () {
$('#EmployeeId').val("fgg");
});
Failing this, you will need to verify in your browser's error console that you don't have other script errors causing this to fail. The first example above works correctly in this demonstration.
After updating my entity framework model, I found this error infecting several files in my solution. I simply right clicked on my .edmx file and my TT file and click "Run Custom Tool" and that had me right again after a restart of Visual Studio 2012.
No, you cannot. Google Plus has been discontinued. Clicking any link for any answer here brings me to this text:

From all of us on the Google+ team,
thank you for making Google+ such a special place.
There is one section that reads that the product is continued for "G Suite," but as of Feb., 2020, the chat and social service listed for G Suite is Hangouts, not Google+.
The format https://plus.google.com/share?url=YOUR_URL_HERE was documented at https://developers.google.com/+/web/share/, but this documentation has since been removed, probably because no part of Google+ continues in development. If you are feeling nostalgic, you can see what the API used to say with an Archive.org link.
Try to use express.static() if you are using Node.js.
You simply need to pass the name of the directory where you keep your static assets, to the express.static middleware to start serving the files directly. For example, if you keep your images, CSS, and JavaScript files in a directory named public, you can do as below -
i.e. : app.use(express.static('public'));
This approach resolved my issue.
Thanks,
Based on my own similar experiences, the solution offered by Strahinja Kustudic above is by far the best. As others have pointed out, simply doing hard reset will remove all the untracked files which could include lots of things that you don't want removed, such as config files. What is safer, is to remove only the files that are about to be added, and for that matter, you'd likely also want to checkout any locally-modified files that are about to be updated.
That in mind, I updated Kustudic's script to do just that. I also fixed a typo (a missing ' in the original).
#/bin/sh
# Fetch the newest code
git fetch
# Delete all files which are being added,
# so there are no conflicts with untracked files
for file in `git diff HEAD..origin/master --name-status | awk '/^A/ {print $2}'`
do
echo "Deleting untracked file $file..."
rm -vf "$file"
done
# Checkout all files which have been locally modified
for file in `git diff HEAD..origin/master --name-status | awk '/^M/ {print $2}'`
do
echo "Checking out modified file $file..."
git checkout $file
done
# Finally merge all the changes (you could use merge here as well)
git pull

On my Windows 7 laptop, I use 'adb logcat | find "com.example.name"' to filter the system program related logcat output from the rest. The output from the logcat program is piped into the find command. Every line that contains 'com.example.name' is output to the window. The double quotes are part of the find command.
To include the output from my Log commands, I use the package name, here "com.example.name", as part of the first parameter in my Log commands like this:
Log.d("com.example.name activity1", "message");
Note: My Samsung Galaxy phone puts out a lot less program related output than the Level 17 emulator.
In Swift 3.0
let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
In older swift: Do something like this:
let screenSize: CGRect = UIScreen.mainScreen().bounds
then you can access the width and height like this:
let screenWidth = screenSize.width
let screenHeight = screenSize.height
if you want 75% of your screen's width you can go:
let screenWidth = screenSize.width * 0.75
Swift 4.0
// Screen width.
public var screenWidth: CGFloat {
return UIScreen.main.bounds.width
}
// Screen height.
public var screenHeight: CGFloat {
return UIScreen.main.bounds.height
}
In Swift 5.0
let screenSize: CGRect = UIScreen.main.bounds
Clustered Index
Clustered indexes sort and store the data rows in the table or view based on their key values. These are the columns included in the index definition. There can be only one clustered index per table, because the data rows themselves can be sorted in only one order.
The only time the data rows in a table are stored in sorted order is when the table contains a clustered index. When a table has a clustered index, the table is called a clustered table. If a table has no clustered index, its data rows are stored in an unordered structure called a heap.
Nonclustered
Nonclustered indexes have a structure separate from the data rows. A nonclustered index contains the nonclustered index key values and each key value entry has a pointer to the data row that contains the key value. The pointer from an index row in a nonclustered index to a data row is called a row locator. The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table. For a heap, a row locator is a pointer to the row. For a clustered table, the row locator is the clustered index key.
You can add nonkey columns to the leaf level of the nonclustered index to by-pass existing index key limits, and execute fully covered, indexed, queries. For more information, see Create Indexes with Included Columns. For details about index key limits see Maximum Capacity Specifications for SQL Server.
Not sure what you are asking, but... Class.forname, maybe?
I think it would be better to write like this.
git rm --cache *//UserInterfaceState.xcuserstate**
Are you sure that your configuration file (web.config) is at the right place and the connection string is really in the (generated) file? If you publish your file, the content of web.release.config might be copied.
The configuration and the access to the Connection string looks all right to me. I would always add a providername
<connectionStrings>
<add name="Dbconnection"
connectionString="Server=localhost; Database=OnlineShopping;
Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
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.
Sorry for comment in an old post but if you want to use an else if statement this will help you

there are several way, one i would prefer is using a table in html. you can add two coloum three rows table and place the radio buttons and lable.
<table border="0">
<tr>
<td><input type="radio" name="sex" value="1"></td>
<td>radio1</td>
</tr>
<tr>
<td><input type="radio" name="sex" value="2"></td>
<td>radio2</td>
</tr>
</table>
You shouldn't worry about this extra call costing you efficiency problems. If there's any cost, it'll be minimal, and should be negligible in the bigger picture of things.
Perhaps the reason why both exist is to offer readability. In the context of many types being converted to String, then various calls to String.valueOf(SomeType) may be more readable than various SomeType.toString calls.
Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this
struct constexpr_str {
char const* str;
std::size_t size;
// can only construct from a char[] literal
template <std::size_t N>
constexpr constexpr_str(char const (&s)[N])
: str(s)
, size(N - 1) // not count the trailing nul
{}
};
int main()
{
constexpr constexpr_str s("constString");
// its .size is a constexpr
std::array<int, s.size> a;
return 0;
}
First off, you have to specify you wish to use Document Literal style:
$client = new SoapClient(NULL, array(
'location' => 'https://example.com/path/to/service',
'uri' => 'http://example.com/wsdl',
'trace' => 1,
'use' => SOAP_LITERAL)
);
Then, you need to transform your data into a SoapVar; I've written a simple transform function:
function soapify(array $data)
{
foreach ($data as &$value) {
if (is_array($value)) {
$value = soapify($value);
}
}
return new SoapVar($data, SOAP_ENC_OBJECT);
}
Then, you apply this transform function onto your data:
$data = soapify(array(
'Acquirer' => array(
'Id' => 'MyId',
'UserId' => 'MyUserId',
'Password' => 'MyPassword',
),
));
Finally, you call the service passing the Data parameter:
$method = 'Echo';
$result = $client->$method(new SoapParam($data, 'Data'));
I'm doing it this way:
function f(data,d){
console.log(d);
console.log(data);
}
$.ajax({
url:u,
success:function(data){ f(data,d); }
});
This should be all you need for a basic setup
This kind of configuration doesn't break phpMyAdmin on localhost
A static IP is recommended on the device running the server
This example uses the 192.168.1.x IP. Your network configuration might use a different IP
In the httpd.conf in Apache you should have:
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 80
I would leave blank the name so it gets the defaults:
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
Allow the guest machines and yourself. As a security caution, you might avoid Allow from all but instead use specific guest IP for example Allow from 192.168.1.xxx where xxx is the guest machine IP. In this case you might need to consider static IPs on guest machines also

To begin with, this line of code:
while ((bytesRead = fis.read(byteArray)) != -1)
is equivalent to
while ((bytesRead = fis.read(byteArray, 0, byteArray.length)) != -1)
So it's writing into the byteArray from offset 0, rather than from where you wrote to before.
You need something like this:
int offset = 0;
int bytesRead = 0;
while ((bytesRead = fis.read(byteArray, offset, byteArray.length - offset) != -1) {
offset += bytesRead;
}
After you have read the data (bytes) in then, you can convert it to Base64.
There are bigger problems though - you're using a fixed size array, so files that are too big won't be converted correctly, and the code is tricker because of it too.
I would ditch the byte array and go with something like this:
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
// commons-io IOUtils
IOUtils.copy(fis, buffer);
byte [] data = buffer.toByteArray();
Base64.encode(data);
Or condense it further as Thilo has with FileUtils.
I faced the same problem and solved it. You need to uninstall the Android plugin entirely from within Eclipse (from the "about" section..), including trace view..
Then added the ADT Plugin again (https://dl-ssl.google.com/android/eclipse/) and install it.
The problem is solved!
I guess it's a bug with the SDK manager or ADT Plugin update mechanism...
Although this post seems to be old, I'd like to add the following two to inform about the recent development in this area for Android:
android-binding - Providing a framework that enabes the binding of android view widgets to data model. It helps to implement MVC or MVVM patterns in android applications.
roboguice - RoboGuice takes the guesswork out of development. Inject your View, Resource, System Service, or any other object, and let RoboGuice take care of the details.
With performance penalty and if you need todo it only in SQL you can use the FORMAT function and 3 REPLACE :
After the format replace the . with another char for example @, then replace the , with a . and then the chararacter you choose by a , which lead you for your example to 1.111,00
SELECT REPLACE(REPLACE(REPLACE(FORMAT("1111.00", 2), ".", "@"), ",", "."), "@", ",")
You can simply get round icon using this code:
<a class="facebook-share-button social-icons" href="#" target="_blank">
<i class="fab fa-facebook socialicons"></i>
</a>
Now your CSS will be:
.social-icons {
display: inline-block;border-radius: 25px;box-shadow: 0px 0px 2px #888;
padding: 0.5em;
background: #0D47A1;
font-size: 20px;
}
.socialicons{color: white;}
If you know the structure of the json that you're receiving then I'd suggest having a class structure that mirrors what you're receiving in json.
Then you can call its something like this...
AddressMap addressMap = JsonConvert.DeserializeObject<AddressMap>(json);
(Where json is a string containing the json in question)
If you don't know the format of the json you've receiving then it gets a bit more complicated and you'd probably need to manually parse it.

Just create another class and add along with the bootstrap container class. You can also use container-fluid though.
<div class="container full-width">

min-width: 100%;
max-width: 100%;
}

This is for anyone that is trying to get a list of all files in a folder and its sub-folders and save it in a text document.
Below is the full code including the “using” statements, “namespace”, “class”, “methods” etc.
I tried commenting as much as possible throughout the code so you could understand what each part is doing.
This will create a text document that contains a list of all files in all folders and sub-folders of any given root folder. After all, what good is a list (like in Console.WriteLine) if you can’t do something with it.
Here I have created a folder on the C drive called “Folder1” and created a folder inside that one called “Folder2”. Next I filled folder2 with a bunch of files, folders and files and folders within those folders.
This example code will get all the files and create a list in a text document and place that text document in Folder1.
Caution: you shouldn’t save the text document to Folder2 (the folder you are reading from), that would be just bad practice. Always save it to another folder.
I hope this helps someone down the line.

BLOB :
BLOB (Binary Large Object) is a large object data type in the database system. BLOB could store a large chunk of data, document types and even media files like audio or video files. BLOB fields allocate space only whenever the content in the field is utilized. BLOB allocates spaces in Giga Bytes.
USAGE OF BLOB :
You can write a binary large object (BLOB) to a database as either binary or character data, depending on the type of field at your data source. To write a BLOB value to your database, issue the appropriate INSERT or UPDATE statement and pass the BLOB value as an input parameter. If your BLOB is stored as text, such as a SQL Server text field, you can pass the BLOB as a string parameter. If the BLOB is stored in binary format, such as a SQL Server image field, you can pass an array of type byte as a binary parameter.

My use case was I wanted to replace

find . -name "*.library" -print0 | xargs -0 sed -i '' -e 's/foo:\/Drive_Letter:/foo:\/bar\/baz\/xyz/g'
hope that helped.
UPDATE s|foo:/Drive_letter:|foo:/ba/baz/xyz|g
I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.
It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.
Use a comma ","
eg:
UPDATE my_table SET rowOneValue = rowOneValue + 1, rowTwoValue = rowTwoValue + ( (rowTwoValue / (rowTwoValue) ) + ?) * (v + 1) WHERE value = ?
If you are Clion/anyOtherJetBrainsIDE user, and yourFile.exe cause this problem, just delete it and let the app create and link it with libs from a scratch. It helps.

You might also consider using the open source SpringSandwich library which lets you directly annotate in your Spring Boot controllers which interceptors to apply, much in the same way you annotate your url routes.
That way, no typo-prone Strings floating around -- SpringSandwich's method and class annotations easily survive refactoring and make it clear what's being applied where. (Disclosure: I'm the author).

You don't have that kind of control with a bare a tag. But you can hook up the tag's onclick handler to call window.open(...) with the right parameters. See here for examples:
https://developer.mozilla.org/En/DOM/Window.open
I still don't think you can force window over tab directly though-- that depends on the browser and the user's settings.
Note, until now posted solutions only work for png and jpg!
If you want it even easier without importing further libraries or you want to display an animated or not animated GIF File in your Ipython Notebook. Transform the line where you want to display it to markdown and use this nice short hack!

?>You need to delimit each parameter name with a ":" at the very least. Technically the name is optional, but it is recommended for readability. So you could write:
- (NSMutableArray*)getBusStops:(NSString*)busStop :(NSSTimeInterval*)timeInterval;
or what you suggested:
- (NSMutableArray*)getBusStops:(NSString*)busStop forTime:(NSSTimeInterval*)timeInterval;
Like this:
var myString = "19 51 2.108997";
var stringParts = myString.split(" ");
var html = "<span>" + stringParts[0] + " " + stringParts[1] + "</span> <span>" + stringParts[2] + "</span";
Here's an example:
#Create a data frame
> d<- data.frame(a=1:3, b=2:4)
> d
a b
1 1 2
2 2 3
3 3 4
#currently, there are no levels in the `a` column, since it's numeric as you point out.
> levels(d$a)
NULL
#Convert that column to a factor
> d$a <- factor(d$a)
> d
a b
1 1 2
2 2 3
3 3 4
#Now it has levels.
> levels(d$a)
[1] "1" "2" "3"
You can also handle this when reading in your data. See the colClasses and stringsAsFactors parameters in e.g. readCSV().
Note that, computationally, factoring such columns won't help you much, and may actually slow down your program (albeit negligibly). Using a factor will require that all values are mapped to IDs behind the scenes, so any print of your data.frame requires a lookup on those levels -- an extra step which takes time.
Factors are great when storing strings which you don't want to store repeatedly, but would rather reference by their ID. Consider storing a more friendly name in such columns to fully benefit from factors.
The following CSS changes in bold (plus a bunch of content in the columns to test scrolling) will work. See the result in this Pen.
.content { flex: 1; display: flex; height: 1px; }
.column { padding: 20px; border-right: 1px solid #999; overflow: auto; }
The trick seems to be that a scrollable panel needs to have a height literally set somewhere (in this case, via its parent), not just determined by flexbox. So even height: 1px works. The flex-grow:1 will still size the panel to fit properly.
You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.
I think what you were looking for in your Range was this:
Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete
Just change the column letters to match your needs.

You can use serialize() like this:
$.ajax({
cache: false,
url: 'test.php',
data: $('form').serialize(),
datatype: 'json',
success: function(data) {
}
});

fragmentManager.beginTransaction()
.remove(fragmentRemove)
.commit();
// fix by @Ogbe
fragmentManager.popBackStackImmediate(tag.toString(),
FragmentManager.POP_BACK_STACK_INCLUSIVE);
}
}
You can use the Pattern class for this. If you want to match only word characters inside the {} then you can use the following regex. \w is a shorthand for [a-zA-Z0-9_]. If you are ok with _ then use \w or else use [a-zA-Z0-9].
String URL = "https://localhost:8080/sbs/01.00/sip/dreamworks/v/01.00/cui/print/$fwVer/{$fwVer}/$lang/en/$model/{$model}/$region/us/$imageBg/{$imageBg}/$imageH/{$imageH}/$imageSz/{$imageSz}/$imageW/{$imageW}/movie/Kung_Fu_Panda_two/categories/3D_Pix/item/{item}/_back/2?$uniqueID={$uniqueID}";
Pattern pattern = Pattern.compile("/\\{\\w+\\}/");
Matcher matcher = pattern.matcher(URL);
if (matcher.find()) {
System.out.println(matcher.group(0)); //prints /{item}/
} else {
System.out.println("Match not found");
}
Javascript only has 1-dimensional arrays, but you can build arrays of arrays, as others pointed out.
The following function can be used to construct a 2-d array of fixed dimensions:
function Create2DArray(rows) {
var arr = [];
for (var i=0;i<rows;i++) {
arr[i] = [];
}
return arr;
}
The number of columns is not really important, because it is not required to specify the size of an array before using it.
Then you can just call:
var arr = Create2DArray(100);
arr[50][2] = 5;
arr[70][5] = 7454;
// ...
If you happen to process the value with some string function before saving, make sure the function can properly handle multibyte characters. String functions that cannot do that and are, say, attempting to truncate might split one of the single multibyte characters in the middle, and that can cause such string error situations.
In PHP for instance, you would need to switch from substr to mb_substr.

The second way is an ANSI standard and therefore should work on all ANSI compliant databases.
To clarify, a database created under SQL Server 2008 R2 was being opened in an instance of SQL Server 2008 (the version prior to R2). The solution for me was to simply perform an upgrade installation of SQL Server 2008 R2. I can only speak for the Express edition, but it worked.
Oddly, though, the Web Platform Installer indicated that I had Express R2 installed. The better way to tell is to ask the database server itself:
SELECT @@VERSION
if (!s.match(/abc|def/g)) {
alert("match");
}
else {
alert("no match");
}
I want to output a table where each column has the smallest possible width,
where columns are padded with white space (but this can be changed) and rows are separated by newlines (but this can be changed) and where each item is formatted using str (but...).
def ftable(tbl, pad=' ', sep='\n', normalize=str):
# normalize the content to the most useful data type
strtbl = [[normalize(it) for it in row] for row in tbl]
# next, for each column we compute the maximum width needed
w = [0 for _ in tbl[0]]
for row in strtbl:
for ncol, it in enumerate(row):
w[ncol] = max(w[ncol], len(it))
# a string is built iterating on the rows and the items of `strtbl`:
# items are prepended white space to an uniform column width
# formatted items are `join`ed using `pad` (by default " ")
# eventually we join the rows using newlines and return
return sep.join(pad.join(' '*(wid-len(it))+it for wid, it in zip(w, row))
for row in strtbl)
The function signature, ftable(tbl, pad=' ', sep='\n', normalize=str), with its default arguments is intended to
provide for maximum flexibility.
You can customize
pad='&', sep='\\\\\n' to have the bulk of a LaTeX table)str but if
you know that all your data is floating point lambda item:
"%.4f"%item could be a reasonable choice, etc.Superficial testing:
I need some test data, possibly involving columns of different width so that the algorithm needs to be a little more sophisticated (but just a little bit;)

I suggest you use a HiddenField inside template field use FindControl to find this field.
ie:
ASPX
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="hfFname" runat="server" Value='<%# Eval("FileName") %>' />
</ItemTemplate>
</asp:TemplateField>
Code behind
protected void gvAttachments_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
GridView gv1 = (GridView)sender;
GridViewRow gvr1 = (GridViewRow)gv1.Rows[e.RowIndex];
//get hidden field value and not directly from the GridviewRow, as that will be null or empty!
HiddenField hf1 = (HiddenField)gvr1.FindControl("hfFname");
if (hf1 != null)
{
..
}
}
Manually editing firefox's settings is the way to go, but it's inconvenient when you need to do it often.
Instead, you can install an add-on that will do it for you in one click.

There was made some changes to the select2 events names (I think on v. 4 and later) so the '-' is changed into this ':'.

You can check all the events at the 'select2' plugin site: select2 Events

You can avoid the repetition with an attribute test instead:
a/b/*[local-name()='c' or local-name()='d' or local-name()='e']
Contrary to Dimitre's antagonistic opinion, the above is not incorrect in a vacuum where the OP has not specified the interaction with namespaces. The self:: axis is namespace restrictive, local-name() is not. If the OP's intention is to capture c|d|e regardless of namespace (which I'd suggest is even a likely scenario given the OR nature of the problem) then it is "another answer that still has some positive votes" which is incorrect.
You can't be definitive without definition, though I'm quite happy to delete my answer as genuinely incorrect if the OP clarifies his question such that I am incorrect.
The easiest way that I know of to get the number of entries in a table is with '#'. #tableName gets the number of entries as long as they are numbered:
tbl={
[1]
[2]
[3]
[4]
[5]
}
print(#tbl)--prints the highest number in the table: 5
Sadly, if they are not numbered, it won't work.
Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.
NB - You need to do this first on a test copy of your table!
When I did it, I found that unless I also included AND n1.id <> n2.id, it deleted every row in the table.
If you want to keep the row with the lowest id value:
DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
If you want to keep the row with the highest id value:
DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
I used this method in MySQL 5.1
Not sure about other versions.
Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE, please be advised that using INSERT and DISTINCT is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE, it took more than 2 hours and yet didn't complete.
INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
SELECT DISTINCT cellId,attributeId,entityRowId,value
FROM tableName;
In Oracle 11g, if you want to search any text in whole database or procedure below mentioned query can be used:
select * from user_source WHERE UPPER(text) LIKE '%YOUR SAGE%'
Here you go :
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/t", "", "");
Statement st = con.createStatement();
String sql = ("SELECT * FROM posts ORDER BY id DESC LIMIT 1;");
ResultSet rs = st.executeQuery(sql);
if(rs.next()) {
int id = rs.getInt("first_column_name");
String str1 = rs.getString("second_column_name");
}
con.close();
In rs.getInt or rs.getString you can pass column_id starting from 1, but i prefer to pass column_name as its more informative as you don't have to look at database table for which index is what column.
UPDATE : rs.next
boolean next() throws SQLException
Moves the cursor froward one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.
When a call to the next method returns false, the cursor is positioned after the last row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown. If the result set type is TYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will return false or throw an SQLException on a subsequent call to next.
If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.
Returns: true if the new current row is valid; false if there are no more rows Throws: SQLException - if a database access error occurs or this method is called on a closed result set
cursor.execute(sql,array)
Only takes two arguments.
It will iterate the "array"-object and match ? in the sql-string.
(with sanity checks to avoid sql-injection)
I was running in to a problem with the standard way to do this:
$string = "one";
$float = (float)$string;
echo $float; : ( Prints 0 )
If there isn't a valid number, the parser shouldn't return a number, it should throw an error. (This is a condition I'm trying to catch in my code, YMMV)
To fix this I have done the following:
$string = "one";
$float = is_numeric($string) ? (float)$string : null;
echo $float; : ( Prints nothing )
Then before further processing the conversion, I can check and return an error if there wasn't a valid parse of the string.
As said above you can put it inside a ScrollView... and if you want the Scroll View to be horizontal put it inside HorizontalScrollView... and if you want your component (or layout) to support both put inside both of them like this:
<HorizontalScrollView>
<ScrollView>
<!-- SOME THING -->
</ScrollView>
</HorizontalScrollView>
and with setting the layout_width and layout_height ofcourse.
function callServlet()
{
document.getElementById("adminForm").action="./Administrator";
document.getElementById("adminForm").method = "GET";
document.getElementById("adminForm").submit();
}
<button type="submit" onclick="callServlet()" align="center"> Register</button>
You need to use a delegated event handler, as the #add elements dynamically appended won't have the click event bound to them. Try this:
$("#buildyourform").on('click', "#add", function() {
// your code...
});
Also, you can make your HTML strings easier to read by mixing line quotes:
var fieldWrapper = $('<div class="fieldwrapper" name="field' + intId + '" id="field' + intId + '"/>');
Or even supplying the attributes as an object:
var fieldWrapper = $('<div></div>', {
'class': 'fieldwrapper',
'name': 'field' + intId,
'id': 'field' + intId
});
You can use it like this: http://plnkr.co/edit/vtNjEgmpItqxX5fdwtPi?p=preview
Like you found, filter accepts predicate function which accepts item
by item from the array.
So, you just have to create an predicate function based on the given criteria.
In this example, criteriaMatch is a function which returns a predicate
function which matches the given criteria.
template:
<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
{{ item }}
</div>
scope:
$scope.criteriaMatch = function( criteria ) {
return function( item ) {
return item.name === criteria.name;
};
};
$filename = pathinfo( parse_url( $url, PHP_URL_PATH ), PATHINFO_FILENAME );
Use parse_url to extract the path from the URL, then pathinfo returns the filename from the path
bool is a fundamental datatype in C++. Converting true to an integer type will yield 1, and converting false will yield 0 (4.5/4 and 4.7/4). In C, until C99, there was no bool datatype, and people did stuff like
enum bool {
false, true
};
So did the Windows API. Starting with C99, we have _Bool as a basic data type. Including stdbool.h will typedef #define that to bool and provide the constants true and false. They didn't make bool a basic data-type (and thus a keyword) because of compatibility issues with existing code.

.loadKeyMaterial(keyStore, "helloworld".toCharArray())
//.loadTrustMaterial(trustStore, new TrustSelfSignedStrategy()) //custom trust store

// Allow TLSv1 protocol only

sslcontext,

It is not quite as baked-in in Java, so you don't get this for free. It is done with convention rather than language constructs. In all data transfer classes (and maybe even in all classes you write...), you should implement a sensible toString method. So here you need to override toString() in your Person class and return the desired state.
There are utilities available that help with writing a good toString method, or most IDEs have an automatic toString() writing shortcut.
If you have a Decimal or similar numeric type, you can use:
Math.Round(myNumber, 2)
EDIT: So, in your case, it would be:
Public Class Form1
Private Sub btncalc_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles btncalc.Click
txtA.Text = Math.Round((Val(txtD.Text) / Val(txtC.Text) * Val(txtF.Text) / Val(txtE.Text)), 2)
txtB.Text = Math.Round((Val(txtA.Text) * 1000 / Val(txtG.Text)), 2)
End Sub
End Class
i could have been only one who made this mistake but maybe not so i'll post.
the format for annotations in the comments before a route has to start with a slash and two asterisks. i was making the mistake of a slash and only one asterisk, which PHPStorm autocompleted.
my route looked like this:
/*
* @Route("/",name="homepage")
*/
public function indexAction(Request $request) {
return $this->render('default/index.html.twig');
}
when it should have been this
/**

*/
public function indexAction(Request $request) {
return $this->render('default/base.html.twig');

I spent more than a week to convert the whole project and came to a solution below:
First, de-integrate the cocopods dependency from the project and then start converting the project to the latest swift version.
Go to Project Directory in the Terminal and Type:
pod deintegrate
This will de-integrate cocopods from the project and No traces of CocoaPods will be left in the project. But at the same time, it won't delete the xcworkspace and podfiles. It's ok if they are present.
Now you have to open xcodeproj(not xcworkspace) and you will get lots of errors because you have called cocoapods dependency methods in your main projects.
So to remove those errors you have two options:
Once all the errors get removed you can convert the code to the latest swift version.
Sometimes if you are getting weird errors then try cleaning derived data and try again.
I don't know why but you have to add a setTimeout with at least for me 200ms:
setTimeout( function() {$("#DIV_ID").scrollTop(0)}, 200 );

# indicates that the following line is a preprocessor directive and should be processed by the preprocessor before compilation by the compiler.
So, #include is a preprocessor directive that tells the preprocessor to include header files in the program.
< > indicate the start and end of the file name to be included.
iostream is a header file that contains functions for input/output operations (cin and cout).
Now to sum it up C++ to English translation of the command, #include <iostream> is:
Dear preprocessor, please include all the contents of the header file iostream at the very beginning of this program before compiler starts the actual compilation of the code.

I used Grim's technique with a little change: If someone looking for this query is because can't do a simple query due to primary key problem:
INSERT INTO table SELECT * FROM table WHERE primakey=1;
With my MySql install 5.6.26, key isn't nullable and produce an error:
#1048 - Column 'primakey' cannot be null
So after create temporary table I change the primary key to a be nullable.
CREATE TEMPORARY TABLE tmptable_1 SELECT * FROM table WHERE primarykey = 1;
ALTER TABLE tmptable_1 MODIFY primarykey int(12) null;
UPDATE tmptable_1 SET primarykey = NULL;
INSERT INTO table SELECT * FROM tmptable_1;
DROP TEMPORARY TABLE IF EXISTS tmptable_1;
for me it only worked with !important in css

search_list = ['one', 'two', 'there']
long_string = 'some one long two phrase three'
if re.compile('|'.join(search_list),re.IGNORECASE).search(long_string): #re.IGNORECASE is used to ignore case
# Do Something if word is present
else:
# Do Something else if word is not present
For some unexplained reason this solution doesn't work for me (maybe some incompatibility of types), so I came up with a solution for myself:
HttpResponseMessage response = await client.GetAsync("api/yourcustomobjects");
if (response.IsSuccessStatusCode)
{
var data = await response.Content.ReadAsStringAsync();
var product = JsonConvert.DeserializeObject<Product>(data);
}
This way my content is parsed into a JSON string and then I convert it to my object.
locals in Rails 4.2+In Rails 4.2 I had to remove the locals part and just use size: 30 instead. Otherwise, it wouldn't pass the local variable correctly.
For example, use this:
<%= render @users, size: 30 %>
On the Unity Editor open your project and:
If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:
cd to/your/unity/project/folder
git init
git add *
git commit -m "First commit"
git remote add origin [email protected]:username/project.git
git push -u origin master
You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).
Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.
And here's my own .gitignore recipe for my Unity projects:

I came from PHP, where you can increment char (A to B, Z to AA, AA to AB etc.) using ++ operator. I made a simple function which does the same in Python. You can also change list of chars to whatever (lowercase, uppercase, etc.) is your need.
# Increment char (a -> b, az -> ba)
def inc_char(text, chlist = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'):
# Unique and sort
chlist = ''.join(sorted(set(str(chlist))))
chlen = len(chlist)
if not chlen:
return ''
text = str(text)
# Replace all chars but chlist
text = re.sub('[^' + chlist + ']', '', text)
if not len(text):
return chlist[0]
# Increment
inc = ''
over = False
for i in range(1, len(text)+1):
lchar = text[-i]
pos = chlist.find(lchar) + 1
if pos < chlen:
inc = chlist[pos] + inc
over = False
break
else:
inc = chlist[0] + inc
over = True
if over:
inc += chlist[0]
result = text[0:-len(inc)] + inc
return result
What you're seeing is integer division. To get floating point division by default,
from __future__ import division
Or, you could convert 1 or 2 of 1/2 into a floating point value.
sqrt = x**(1.0/2)
exec is shelling to the operating system, and unless the OS has some special way of knowing how to execute a file, then it's going to default to treating it as a shell script or similar. In this case, it has no idea how to run your php file. If this script absolutely has to be executed from a shell, then either execute php passing the filename as a parameter, e.g
exec ('/usr/local/bin/php -f /opt/lampp/htdocs/.../name.php)') ;
or use the punct at the top of your php script
#!/usr/local/bin/php
<?php ... ?>
In addtion to align-self you can also consider auto margin which will do almost the same thing

</div>In my opinion this is a serious language flaw that puts SQL light years behind other languages. This is my incredibly hacky workaround. It is a total kludge but it always works.
Before I do I want to draw attention to @Peter Mortensen's answer, which in my opinion is the correct answer. The only reason I do the below instead is because most implementations of SQL have incredibly slow join operations and force you to break "don't repeat yourself". I need my queries to populate fast.
Also this is an old way of doing things. STRING_AGG and STRING_SPLIT are a lot cleaner. Again I do it this way because it always works.
-- remember Substring is 1 indexed, not 0 indexed
SELECT ProductId
, SUBSTRING (
MAX(enc.pnameANDoq), 1, CHARINDEX(';', MAX(enc.pnameANDoq)) - 1
) AS ProductName
, SUM ( CAST ( SUBSTRING (
MAX(enc.pnameAndoq), CHARINDEX(';', MAX(enc.pnameANDoq)) + 1, 9999
) AS INT ) ) AS OrderQuantity
FROM (
SELECT CONCAT (ProductName, ';', CAST(OrderQuantity AS VARCHAR(10)))
AS pnameANDoq, ProductID
FROM OrderDetails
) enc
GROUP BY ProductId
Or in plain language :
Performance wise I have always had superior performance using strings over things like, say, bigints. At least with microsoft and oracle substring is a fast operation.
This avoids the problems you run into when you use MAX() where when you use MAX() on multiple fields they no longer agree and come from different rows. In this case your data is guaranteed to be glued together exactly the way you asked it to be.
To access a 3rd or 4th field, you'll need nested substrings, "after the first semicolon look for a 2nd". This is why STRING_SPLIT is better if it is available.
Note : While outside the scope of your question this is especially useful when you are in the opposite situation and you're grouping on a combined key, but don't want every possible permutation displayed, that is you want to expose 'foo' and 'bar' as a combined key but want to group by 'foo'
The following example builds on MARTIN DE LA FUENTE SAAVEDRA's excellent work and accepted answer. In particular, two enumerations are introduced. The first allows for easy specification of how an elevated program is to be opened, and the second helps when errors need to be easily identified. Please note that if you want all command line arguments passed to the new process, sys.argv[0] should probably be replaced with a function call: subprocess.list2cmdline(sys.argv).

I had the same problem. solved it like this:
return new ModelAndView("redirect:/user/list?success=true");
And then my controller method look like this:
public ModelMap list(@RequestParam(required=false) boolean success) {
ModelMap mm = new ModelMap();
mm.put(SEARCH_MODEL_KEY, campaignService.listAllCampaigns());
if(success)
mm.put("successMessageKey", "campaign.form.msg.success");
return mm;
}
Works perfectly unless you want to send simple data, not collections let's say. Then you'd have to use session I guess.

Update: Visual Studio 2019 (Clean [bin] and [obj] before release). However I am not sure if [obj] needs to be deleted. Be aware there is nuget package configuration placed too. You can remove the second line if you think so.

Well, there is an array type in recent Postgres versions (not 100% about PG 7.4). You can even index them, using a GIN or GIST index. The syntaxes are:
create table foo (
bar int[] default '{}'
);
select * from foo where bar && array[1] -- equivalent to bar && '{1}'::int[]
create index on foo using gin (bar); -- allows to use an index in the above query
But as the prior answer suggests, it will be better to normalize properly.
Make sure you restart your computer after you install the Build Tools.
This was what was causing the error for me.
Lazy simple version for forgetfuls like me:
git rebase -i HEAD~3
or however many commits instead of 3.
Turn this
pick YourCommitMessageWhatever
pick YouGetThePoint
pick IdkManItsACommitMessage
into this
pick YourCommitMessageWhatever
s YouGetThePoint
s IdkManItsACommitMessage
and do some action where you hit esc then enter to save the changes. [1]
When the next screen comes up, get rid of those garbage # lines [2] and create a new commit message or something, and do the same escape enter action. [1]
Wowee, you have fewer commits. Or you just broke everything.
[1] - or whatever works with your git configuration. This is just a sequence that's efficient given my setup.
[2] - you'll see some stuff like # this is your n'th commit a few times, with your original commits right below these message. You want to remove these lines, and create a commit message to reflect the intentions of the n commits that you're combining into 1.

Just for a sake of completeness, if you need to find all positions of a character in a string, you can do the following:
s = 'shak#spea#e'
c = '#'
print([pos for pos, char in enumerate(s) if char == c])
which will print: [4, 9]
If your error handling is very sophisticated and therefore might throw an error itself, it is useful to add a flag indicating if you are already in "errorHandling-Mode". Like so:
var appIsHandlingError = false;
window.onerror = function() {
if (!appIsHandlingError) {
appIsHandlingError = true;
handleError();
}
};
function handleError() {
// graceful error handling
// if successful: appIsHandlingError = false;
}
Otherwise you could find yourself in an infinite loop.

Follow below gitbash commands to push the folder files on github repository :-
1.) $ git init
2.) $ git cd D:\FileFolderName
3.) $ git status
4.) If needed to switch the git branch, use this command :
$ git checkout -b DesiredBranch
5.) $ git add .
6.) $ git commit -m "added a new folder"
7.) $ git push -f https://github.com/username/MyTestApp.git TestBranch
(i.e git push origin branch)
Check what git remote -v returns: the account used to push to an http url is usually embedded into the remote url itself.
https://[email protected]/...
If that is the case, put an url which will force Git to ask for the account to use when pushing:
git remote set-url origin https://github.com/<user>/<repo>
Or one to use the Fre1234 account:
git remote set-url origin https://[email protected]/<user>/<repo>
Also check if you installed your Git For Windows with or without a credential helper as in this question.
The OP Fre1234 adds in the comments:
I finally found the solution.
Go to:Control Panel -> User Accounts -> Manage your credentials -> Windows CredentialsUnder
Generic Credentialsthere are some credentials related to Github,
Click on them and click "Remove".
That is because the default installation for Git for Windows set a Git-Credential-Manager-for-Windows.
See git config --global credential.helper output (it should be manager)
You can use this one for return type of generic list:

return valueType;
}

using 'm_' or '_' in the front of a variable makes it easier to spot member variables in methods throughout an object.
As a side benefit typing 'm_' or '_' will make intellsense pop them up first ;)
A std::map sorted by it's value is in essence a std::set. By far the easiest way is to copy all entries in the map to a set (taken and adapted from here)
template <typename M, typename S>
void MapToSet( const M & m, S & s )
{
typename M::const_iterator end = m.end();
for( typename M::const_iterator it = m.begin(); it != end ; ++it )
{
s.insert( it->second );
}
}
One caveat: if the map contains different keys with the same value, they will not be inserted into the set and be lost.
Wow, the other answers look complex - so I'm hoping I've not missed something obvious.
You can use OVER/PARTITION BY against aggregates, and they'll then do grouping/aggregating without a GROUP BY clause. So I just modified your query to:
select T2.ID AS T2ID
,T2.Name as T2Name
,T2.Orders
,T1.ID AS T1ID
,T1.Name As T1Name
,T1Sum.Price
FROM @t2 T2
INNER JOIN (
SELECT Rel.t2ID
,Rel.t1ID
-- ,MAX(Rel.t1ID)AS t1ID
-- the MAX returns an arbitrary ID, what i need is:
,ROW_NUMBER()OVER(Partition By Rel.t2ID Order By Price DESC)As PriceList
,SUM(Price)OVER(PARTITION BY Rel.t2ID) AS Price
FROM @t1 T1
INNER JOIN @relation Rel ON Rel.t1ID=T1.ID
-- GROUP BY Rel.t2ID
)AS T1Sum ON T1Sum.t2ID = T2.ID
INNER JOIN @t1 T1 ON T1Sum.t1ID=T1.ID
where t1Sum.PriceList = 1
Which gives the requested result set.
What you do here is called a JOIN (although you do it implicitly because you select from multiple tables). This means, if you didn't put any conditions in your WHERE clause, you had all combinations of those tables. Only with your condition you restrict your join to those rows where the drink id matches.
But there are still X multiple rows in the result for every drink, if there are X photos with this particular drinks_id. Your statement doesn't restrict which photo(s) you want to have!
If you only want one row per drink, you have to tell SQL what you want to do if there are multiple rows with a particular drinks_id. For this you need grouping and an aggregate function. You tell SQL which entries you want to group together (for example all equal drinks_ids) and in the SELECT, you have to tell which of the distinct entries for each grouped result row should be taken. For numbers, this can be average, minimum, maximum (to name some).
In your case, I can't see the sense to query the photos for drinks if you only want one row. You probably thought you could have an array of photos in your result for each drink, but SQL can't do this. If you only want any photo and you don't care which you'll get, just group by the drinks_id (in order to get only one row per drink):
SELECT name, price, photo
FROM drinks, drinks_photos
WHERE drinks.id = drinks_id
GROUP BY drinks_id
name price photo
fanta 5 ./images/fanta-1.jpg
dew 4 ./images/dew-1.jpg
In MySQL, we also have GROUP_CONCAT, if you want the file names to be concatenated to one single string:
SELECT name, price, GROUP_CONCAT(photo, ',')
FROM drinks, drinks_photos
WHERE drinks.id = drinks_id
GROUP BY drinks_id
name price photo
fanta 5 ./images/fanta-1.jpg,./images/fanta-2.jpg,./images/fanta-3.jpg
dew 4 ./images/dew-1.jpg,./images/dew-2.jpg
However, this can get dangerous if you have , within the field values, since most likely you want to split this again on the client side. It is also not a standard SQL aggregate function.
A common issue where the favicon will not show up when expected is cache, if your .htaccess for example reads:
ExpiresByType image/x-icon "access plus 1 month"
Then simply add a random value to your favicon reference:
<link rel="shortcut icon" href="https://example.com/favicon.ico?r=31241" type="image/x-icon" />
Works every time for me even with heavy caching.
Three slightly different answers depending how you look at the question:
1) Good enough for the exact question asked is Jonathan Leffler's solution, except that to round up to 16-aligned, you only need 15 extra bytes, not 16.
A:
/* allocate a buffer with room to add 0-15 bytes to ensure 16-alignment */
void *mem = malloc(1024+15);
ASSERT(mem); // some kind of error-handling code
/* round up to multiple of 16: add 15 and then round down by masking */
void *ptr = ((char*)mem+15) & ~ (size_t)0x0F;
B:
free(mem);
2) For a more generic memory allocation function, the caller doesn't want to have to keep track of two pointers (one to use and one to free). So you store a pointer to the 'real' buffer below the aligned buffer.
A:
void *mem = malloc(1024+15+sizeof(void*));
if (!mem) return mem;
void *ptr = ((char*)mem+sizeof(void*)+15) & ~ (size_t)0x0F;
((void**)ptr)[-1] = mem;
return ptr;
B:
if (ptr) free(((void**)ptr)[-1]);
Note that unlike (1), where only 15 bytes were added to mem, this code could actually reduce the alignment if your implementation happens to guarantee 32-byte alignment from malloc (unlikely, but in theory a C implementation could have a 32-byte aligned type). That doesn't matter if all you do is call memset_16aligned, but if you use the memory for a struct then it could matter.
I'm not sure off-hand what a good fix is for this (other than to warn the user that the buffer returned is not necessarily suitable for arbitrary structs) since there's no way to determine programatically what the implementation-specific alignment guarantee is. I guess at startup you could allocate two or more 1-byte buffers, and assume that the worst alignment you see is the guaranteed alignment. If you're wrong, you waste memory. Anyone with a better idea, please say so...
[Added:
The 'standard' trick is to create a union of 'likely to be maximally aligned types' to determine the requisite alignment. The maximally aligned types are likely to be (in C99) 'long long', 'long double', 'void *', or 'void (*)(void)'; if you include <stdint.h>, you could presumably use 'intmax_t' in place of long long (and, on Power 6 (AIX) machines, intmax_t would give you a 128-bit integer type). The alignment requirements for that union can be determined by embedding it into a struct with a single char followed by the union:
struct alignment
{
char c;
union
{
intmax_t imax;
long double ldbl;
void *vptr;
void (*fptr)(void);
} u;
} align_data;
size_t align = (char *)&align_data.u.imax - &align_data.c;
You would then use the larger of the requested alignment (in the example, 16) and the align value calculated above.
On (64-bit) Solaris 10, it appears that the basic alignment for the result from malloc() is a multiple of 32 bytes.
]
In practice, aligned allocators often take a parameter for the alignment rather than it being hardwired. So the user will pass in the size of the struct they care about (or the least power of 2 greater than or equal to that) and all will be well.
3) Use what your platform provides: posix_memalign for POSIX, _aligned_malloc on Windows.
4) If you use C11, then the cleanest - portable and concise - option is to use the standard library function aligned_alloc that was introduced in this version of the language specification.
select into is used in pl/sql to set a variable to field values. Instead, use
create table new_table as select * from old_table
I don't think there is a function that does all that in a single call. However you can find the Gaussian probability density function in scipy.stats.
So the simplest way I could come up with is:
import numpy as np
import matplotlib.pyplot as plt
from scipy.stats import norm
# Plot between -10 and 10 with .001 steps.
x_axis = np.arange(-10, 10, 0.001)
# Mean = 0, SD = 2.
plt.plot(x_axis, norm.pdf(x_axis,0,2))
plt.show()

Here's a complete example of jHackTheRipper's answer for the TL;DR crowd. :-) In this case, I wanted to run g++-4.5 on an Ubuntu system that defaults to 4.6. As root:
apt-get install g++-4.5
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.6 100
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.5 50
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 100
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.5 50
update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-4.6 100
update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-4.5 50
update-alternatives --set g++ /usr/bin/g++-4.5
update-alternatives --set gcc /usr/bin/gcc-4.5
update-alternatives --set cpp-bin /usr/bin/cpp-4.5
Here, 4.6 is still the default (aka "auto mode"), but I explicitly switch to 4.5 temporarily (manual mode). To go back to 4.6:
update-alternatives --auto g++
update-alternatives --auto gcc
update-alternatives --auto cpp-bin
(Note the use of cpp-bin instead of just cpp. Ubuntu already has a cpp alternative with a master link of /lib/cpp. Renaming that link would remove the /lib/cpp link, which could break scripts.)
awk
awk '{gsub(/two.*/,"")}1' file
Ruby
ruby -ne 'print $_.gsub(/two.*/,"")' file
you can use
$('option:selected').next('option')
or
$('option:selected + option')
And set the value:
var nextVal = $('option:selected + option').val();
$('select').val(nextVal);
A code like that should work:
int i = 0;
char string[256], c;
while(i < 256 - 1 && (c = fgetc(fp) != EOF)) //Keep space for the final \0
{
string[i++] = c;
}
string[i] = '\0';
As already stated, log4j.properties should be in a directory included in the classpath, I want to add that in a mavenized project a good place can be src/main/resources/log4j.properties
If you want to execute that command, you should probably change:
PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'
to:
PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)
There can be multiple reasons for this. In my case it was wrong source root issue. Invalidate caches didn't work along with other solutions.
Check your module source roots.
Project Structure (Ctrl+Alt+Shift+S).
Modules
Select your problem module.
Change tab on top of window "Sources".
Remove unwanted source roots. Keep one and add src and test source roots in this root.

solution looks like below
public class MyRestResponse{
private String message;
public void setMessage(String msg){
this.message = msg;
}
public String getMessage(){
return this.message;
}
}
that's how it worked for me
I am using Visual Studio 2013 and Win 8.1. It was Shift + 0 (0 is my insert key) on the number pad of my laptop.
