It's work for me!
This was in response to your other question, that looks like it's been deleted....the point still stands.
Looks like a classic Unicode to ASCII issue. The trick would be to find where it's happening.
.NET works fine with Unicode, assuming it's told it's Unicode to begin with (or left at the default).
My guess is that your receiving app can't handle it. So, I'd probably use the ASCIIEncoder with an EncoderReplacementFallback with String.Empty:
using System.Text;
string inputString = GetInput();
var encoder = ASCIIEncoding.GetEncoder();
encoder.Fallback = new EncoderReplacementFallback(string.Empty);
byte[] bAsciiString = encoder.GetBytes(inputString);
// Do something with bytes...
// can write to a file as is
File.WriteAllBytes(FILE_NAME, bAsciiString);
// or turn back into a "clean" string
string cleanString = ASCIIEncoding.GetString(bAsciiString);
// since the offending bytes have been removed, can use default encoding as well
Assert.AreEqual(cleanString, Default.GetString(bAsciiString));
Of course, in the old days, we'd just loop though and remove any chars greater than 127...well, those of us in the US at least. ;)
For those who want to use Python, here's a simple routine that removes parenthesized substrings, including those with nested parentheses. Okay, it's not a regex, but it'll do the job!
def remove_nested_parens(input_str):
"""Returns a copy of 'input_str' with any parenthesized text removed. Nested parentheses are handled."""
result = ''
paren_level = 0
for ch in input_str:
if ch == '(':
paren_level += 1
elif (ch == ')') and paren_level:
paren_level -= 1
elif not paren_level:
result += ch
return result
remove_nested_parens('example_(extra(qualifier)_text)_test(more_parens).ext')

You can do this with PureBasic and MsScriptControl
All you need to do is pasting the MsScriptControl to the Purebasic editor and add something like this below
InitScriptControl()

Imagine you are developing a web-application and you decide to decouple the functionality from the presentation of the application, because it affords greater freedom.
You create an API and let others implement their own front-ends over it as well. What you just did here is implement an SOA methodology, i.e. using web-services.
Web services make functional building-blocks accessible over standard Internet protocols independent of platforms and programming languages.
So, you design an interchange mechanism between the back-end (web-service) that does the processing and generation of something useful, and the front-end (which consumes the data), which could be anything. (A web, mobile, or desktop application, or another web-service). The only limitation here is that the front-end and back-end must "speak" the same "language".
That's where SOAP and REST come in. They are standard ways you'd pick communicate with the web-service.
SOAP:
SOAP internally uses XML to send data back and forth. SOAP messages have rigid structure and the response XML then needs to be parsed. WSDL is a specification of what requests can be made, with which parameters, and what they will return. It is a complete specification of your API.
REST:
REST is a design concept.
The World Wide Web represents the largest implementation of a system conforming to the REST architectural style.
It isn't as rigid as SOAP. RESTful web-services use standard URIs and methods to make calls to the webservice. When you request a URI, it returns the representation of an object, that you can then perform operations upon (e.g. GET, PUT, POST, DELETE). You are not limited to picking XML to represent data, you could pick anything really (JSON included)
Flickr's REST API goes further and lets you return images as well.
JSON and XML, are functionally equivalent, and common choices. There are also RPC-based frameworks like GRPC based on Protobufs, and Apache Thrift that can be used for communication between the API producers and consumers. The most common format used by web APIs is JSON because of it is easy to use and parse in every language.
$sql = "select count(column_name) as count from table";
Some easy ways:
Use Apache's digest authorization.
Use lighttpd's digest authorization.
Use php's header digest authorization.
If you want you can also make it so only certain ip addresses can login.. :) really easy with lighttpd
Update: I will post some examples soon, so don't vote down for no examples, i just need to get some down for this answer.
If you want to use sessions the following is the best way to go:
# admin.php
session_start();
if(!$_SESSION["AUTH"])
require_once "login.php";
# Do stuff, we are logged in..
# login.php
session_start();
if($_REQUEST["username"] == "user" && $_REQUEST["password"] == "pass")
$_SESSION["AUTH"] = true;
else $_SESSION["AUTH"] = false; # This logs you out if you visit this login script page without login details.
if($_SESSION["AUTH"])
require_once "admin.php";
This method does not contain the examples for above but you seamed interested in this method. The other method examples are still to come, I have not got enough time to get it for apache or lighttpd settings and the php header auth: http://php.net/manual/en/features.http-auth.php Will do.
Another way to do it on Ubuntu 18.0.4
sudo /usr/share/kibana/bin/kibana --version
You can use a query to get the same:
SELECT CONCAT(FirstName , ' ' , MiddleName , ' ' , Lastname) AS Name FROM TableName;
Note: This query return if all columns have some value if anyone is null or empty then it will return null for all, means Name will return "NULL"
To avoid above we can use the IsNull
keyword to get the same.
SELECT Concat(Ifnull(FirstName,' ') ,' ', Ifnull(MiddleName,' '),' ', Ifnull(Lastname,' ')) FROM TableName;
If anyone containing null value the ' ' (space) will add with next value.
You can easlity configure SQLite with swift using single ton class as well.

If your 13 digit "number" is really text, that is you don't intend to do any math on it, you can precede it with an apostrophe
Sheet3.Range("c" & k).Value = "'" & Sheet2.Range("c" & i).Value
But I don't see how a 13 digit number would ever get past the If statement because it would always be greater than 1000. Here's an alternate version
Sub CommandClick()
Dim rCell As Range
Dim rNext As Range
For Each rCell In Sheet2.Range("C1:C30000").Cells
If rCell.Value >= 100 And rCell.Value < 1000 Then
Set rNext = Sheet3.Cells(Sheet3.Rows.Count, 1).End(xlUp).Offset(1, 0)
rNext.Resize(1, 3).Value = rCell.Offset(0, -2).Resize(1, 3).Value
End If
Next rCell
End Sub
HTTP sends bytes. If the resource in question is text, the character encoding is normally specified, either by the Content-Type HTTP header or by another mechanism (an RFC, HTML meta http-equiv
,...).
urllib
should know how to encode the bytes to a string, but it's too naïve—it's a horribly underpowered and un-Pythonic library.
Dive Into Python 3 provides an overview about the situation.
Your "work-around" is fine—although it feels wrong, it's the correct way to do it.

Can you use default android Crop functionality?
Here is my code
private void performCrop(Uri picUri) {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.setDataAndType(picUri, "image/*");
// set crop properties here
cropIntent.putExtra("crop", true);
// indicate aspect of desired crop
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
// indicate output X and Y
cropIntent.putExtra("outputX", 128);
cropIntent.putExtra("outputY", 128);
// retrieve data on return
cropIntent.putExtra("return-data", true);
// start the activity - we handle returning in onActivityResult
startActivityForResult(cropIntent, PIC_CROP);
}
// respond to users whose devices do not support the crop action
catch (ActivityNotFoundException anfe) {
// display an error message
String errorMessage = "Whoops - your device doesn't support the crop action!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
declare:
final int PIC_CROP = 1;
at top.
In onActivity result method, writ following code:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PIC_CROP) {
if (data != null) {
// get the returned data
Bundle extras = data.getExtras();
// get the cropped bitmap
Bitmap selectedBitmap = extras.getParcelable("data");
imgView.setImageBitmap(selectedBitmap);
}
}
}
It is pretty easy for me to implement and also shows darken areas.
If you are using ListBox in your application and you want to return the selected value of ListBox and display it in a Label or any thing else then use this code, it will help you
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
label1.Text = listBox1.SelectedItem.ToString();
}
You can also tell MySQL what database to use (if you have it created already):
mysql -u example_user -p --database=example < ./example.sql
<div>
<div class="a">
A
</div>
</div>?
$(window).scroll(function() {
if ($(this).scrollTop() > 0) {
$('.a').fadeOut();
} else {
$('.a').fadeIn();
}
});
type Services
at search, then start Services
then start all VM services
Check if you have a .git directory in your home folder and if you don't:
mkdir ~/.git
Solved the problem in my case.
To get the value equivalent to your C cast, just bitwise and with the appropriate mask. e.g. if unsigned long
is 32 bit:
>>> i = -6884376
>>> i & 0xffffffff
4288082920
or if it is 64 bit:
>>> i & 0xffffffffffffffff
18446744073702667240
Do be aware though that although that gives you the value you would have in C, it is still a signed value, so any subsequent calculations may give a negative result and you'll have to continue to apply the mask to simulate a 32 or 64 bit calculation.
This works because although Python looks like it stores all numbers as sign and magnitude, the bitwise operations are defined as working on two's complement values. C stores integers in twos complement but with a fixed number of bits. Python bitwise operators act on twos complement values but as though they had an infinite number of bits: for positive numbers they extend leftwards to infinity with zeros, but negative numbers extend left with ones. The &
operator will change that leftward string of ones into zeros and leave you with just the bits that would have fit into the C value.
Displaying the values in hex may make this clearer (and I rewrote to string of f's as an expression to show we are interested in either 32 or 64 bits):
>>> hex(i)
'-0x690c18'
>>> hex (i & ((1 << 32) - 1))
'0xff96f3e8'
>>> hex (i & ((1 << 64) - 1)
'0xffffffffff96f3e8L'
For a 32 bit value in C, positive numbers go up to 2147483647 (0x7fffffff), and negative numbers have the top bit set going from -1 (0xffffffff) down to -2147483648 (0x80000000). For values that fit entirely in the mask, we can reverse the process in Python by using a smaller mask to remove the sign bit and then subtracting the sign bit:
>>> u = i & ((1 << 32) - 1)
>>> (u & ((1 << 31) - 1)) - (u & (1 << 31))
-6884376
Or for the 64 bit version:
>>> u = 18446744073702667240
>>> (u & ((1 << 63) - 1)) - (u & (1 << 63))
-6884376
This inverse process will leave the value unchanged if the sign bit is 0, but obviously it isn't a true inverse because if you started with a value that wouldn't fit within the mask size then those bits are gone.
Notepad++ provides 2 types of features:
Based on what you write, it seems what you want is auto-completion on function only + suggestion on arguments.
To do that, you just need to change a setting.
Settings
> Preferences...
> Auto-completion
Enable Auto-completion on each input
Function completion
and not Word completion
Function parameter hint on input
(if you have this option)On version 6.5.5 of Notepad++, I have this setting
Some documentation about auto-completion is available in Notepad++ Wiki.
RAND(CHECKSUM(NEWID()))
The above will generate a (pseudo-) random number between 0 and 1, exclusive. If used in a select, because the seed value changes for each row, it will generate a new random number for each row (it is not guaranteed to generate a unique number per row however).
Example when combined with an upper limit of 10 (produces numbers 1 - 10):
CAST(RAND(CHECKSUM(NEWID())) * 10 as INT) + 1
Transact-SQL Documentation:
After looking on Super User I found this question which explains how to do this with the shortcut on the start screen. Similarly you can do the same when Visual Studio is pinned to the task bar. In either location:
Properties
Shortcut tab
select Advanced
Run as administrator
Unlike in Windows 7 this only works if you launch the application from the shortcut you changed. After updating both Visual Studio shortcuts it seems to also work when you open a solution file from Explorer.
Update Warning:
It looks like one of the major flaws in running Visual Studio with elevated permissions is since Explorer isn't running with them as well you can't drag and drop files into Visual Studio for editing. You need to open them through the file open dialog. Nor can you double click any file associated to Visual Studio and have it open in Visual Studio (aside from solutions it seems) because you'll get an error message saying There was a problem sending the command to the program.
Once I uncheck to always start with elevated permissions (using VSCommands) then I'm able to open files directly and drop them into an open instance of Visual Studio.
Update For The Daring: Despite there being no UI to turn off UAC like in the past, that I saw at least, you can still do so through the registry. The key to edit is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
EnableLUA - DWORD 1-Enabled, 0-Disabled
After changing this Windows will prompt you to restart. Once restarted you'll be back to everything running with admin permissions if you're an admin. The issues I reported above are now gone as well.
You can use the recode
function from dplyr
.
df <- iris %>%
mutate(Species = recode(Species, setosa = "SETOSA",
versicolor = "VERSICOLOR",
virginica = "VIRGINICA"
)
)
curl -H @<header_file> <host>
Since curl 7.55 headers from file are supported with @<file>
echo 'Cookie: USER_TOKEN=Yes' > /tmp/cookie
curl -H @/tmp/cookie <host>
For me, the following approach works. I think if there is any error after the "FormsAuthentication.SignOut()" statement, SingOut doesn't work.
public ActionResult SignOut()
{
if (Request.IsAuthenticated)
{
FormsAuthentication.SignOut();
return Redirect("~/");
}
return View();
}
How about pyjs?
From the above website:
pyjs is a Rich Internet Application (RIA) Development Platform for both Web and Desktop. With pyjs you can write your JavaScript-powered web applications entirely in Python.
using eval:
var part1name = eval("someObject.part1.name");
wrap to return undefined on error
function path(obj, path) {
try {
return eval("obj." + path);
} catch(e) {
return undefined;
}
}
http://jsfiddle.net/shanimal/b3xTw/
Please use common sense and caution when wielding the power of eval. It's a bit like a light saber, if you turn it on there's a 90% chance you'll sever a limb. Its not for everybody.
Perfectly described in pkozlowski's comment. I had working solution with AngularJS 1.2.6 and ASP.NET Web Api but when I had upgraded AngularJS to 1.3.3 then requests failed.
Solution for Web Api server was to add handling of the OPTIONS requests at the beginning of configuration method (more info in this blog post):
app.Use(async (context, next) =>
{
IOwinRequest req = context.Request;
IOwinResponse res = context.Response;
if (req.Path.StartsWithSegments(new PathString("/Token")))
{
var origin = req.Headers.Get("Origin");
if (!string.IsNullOrEmpty(origin))
{
res.Headers.Set("Access-Control-Allow-Origin", origin);
}
if (req.Method == "OPTIONS")
{
res.StatusCode = 200;
res.Headers.AppendCommaSeparatedValues("Access-Control-Allow-Methods", "GET", "POST");
res.Headers.AppendCommaSeparatedValues("Access-Control-Allow-Headers", "authorization", "content-type");
return;
}
}
await next();
});
Are you talking about gets
?
puts "Enter A"
a = gets.chomp
puts "Enter B"
b = gets.chomp
c = a.to_i + b.to_i
puts c
Something like that?
Kernel.gets
tries to read the params found in ARGV
and only asks to console if not ARGV
found. To force to read from console even if ARGV
is not empty use STDIN.gets
Given that Windows has no sys/socket.h, you might consider just doing something like this:
#ifdef __WIN32__
# include <winsock2.h>
#else
# include <sys/socket.h>
#endif
I know you indicated that you won't use WinSock, but since WinSock is how TCP networking is done under Windows, I don't see that you have any alternative. Even if you use a cross-platform networking library, that library will be calling WinSock internally. Most of the standard BSD sockets API calls are implemented in WinSock, so with a bit of futzing around, you can make the same sockets-based program compile under both Windows and other OS's. Just don't forget to do a
#ifdef __WIN32__
WORD versionWanted = MAKEWORD(1, 1);
WSADATA wsaData;
WSAStartup(versionWanted, &wsaData);
#endif
at the top of main()... otherwise all of your socket calls will fail under Windows, because the WSA subsystem wasn't initialized for your process.
I missed to add
@Controller("userBo") into UserBoImpl class.
The solution for this is adding this controller into Impl class.
There are no buts about it! Who want to grasp the subject must do the following ones,
- Peruse The Lost Art of Structure Packing written by Eric S. Raymond
- Glance at Eric's code example
- Last but not least, don't forget the following rule about padding that a struct is aligned to the largest type’s alignment requirements.
Their names can be a bit confusing :). Here's a summary:
The SelectedItem property returns the entire object that your list is bound to. So say you've bound a list to a collection of Category
objects (with each Category object having Name and ID properties). eg. ObservableCollection<Category>
. The SelectedItem
property will return you the currently selected Category
object. For binding purposes however, this is not always what you want, as this only enables you to bind an entire Category object to the property that the list is bound to, not the value of a single property on that Category object (such as its ID
property).
Therefore we have the SelectedValuePath property and the SelectedValue property as an alternative means of binding (you use them in conjunction with one another). Let's say you have a Product
object, that your view is bound to (with properties for things like ProductName, Weight, etc). Let's also say you have a CategoryID
property on that Product object, and you want the user to be able to select a category for the product from a list of categories. You need the ID property of the Category object to be assigned to the CategoryID
property on the Product object. This is where the SelectedValuePath
and the SelectedValue
properties come in. You specify that the ID property on the Category object should be assigned to the property on the Product object that the list is bound to using SelectedValuePath='ID'
, and then bind the SelectedValue
property to the property on the DataContext (ie. the Product).
The example below demonstrates this. We have a ComboBox bound to a list of Categories (via ItemsSource). We're binding the CategoryID property on the Product as the selected value (using the SelectedValue property). We're relating this to the Category's ID property via the SelectedValuePath property. And we're saying only display the Name property in the ComboBox, with the DisplayMemberPath property).
<ComboBox ItemsSource="{Binding Categories}"
SelectedValue="{Binding CategoryID, Mode=TwoWay}"
SelectedValuePath="ID"
DisplayMemberPath="Name" />
public class Category
{
public int ID { get; set; }
public string Name { get; set; }
}
public class Product
{
public int CategoryID { get; set; }
}
It's a little confusing initially, but hopefully this makes it a bit clearer... :)

You can't bind an event to the element before it exists, so you should do it in the onload
event:
<html>
<head>
<script type="text/javascript">
window.onload = function() {
document.getElementById('foo').addEventListener('click', function (e) {
var img = document.createElement('img');
img.setAttribute('src', 'http://blog.stackoverflow.com/wp-content/uploads/stackoverflow-logo-300.png');
e.target.appendChild(img);
});
};
</script>
</head>
<body>
<img id="foo" src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />
</body>
</html>

In Python 3, print
became a function. This means that you need to include parenthesis now like mentioned below:
print("Hello World")
Ok, I'll try to help you using one my examples. First of all, you need to know I am using express for my application directory structure and for creating files like app.js in an automatically way. My login.html looks like:
...
<div class="form">
<h2>Login information</h2>
<form action="/login" method = "post">
<input type="text" placeholder="E-Mail" name="email" required/>
<input type="password" placeholder="Password" name="password" required/>
<button>Login</button>
</form>
The important thing here is action="/login". This is the path I use in my index.js (for navigating between the views) which look like this:
app.post('/login', passport.authenticate('login', {
successRedirect : '/home',
failureRedirect : '/login',
failureFlash : true
}));
app.get('/home', function(request, response) {
response.render('pages/home');
});
This allows me to redirect to another page after a succesful login. There is a helpful tutorial you could check out for redirecting between pages:
http://cwbuecheler.com/web/tutorials/2014/restful-web-app-node-express-mongodb/
To read a statement like <%= user.attributes.name %> let's have a look at a simple profile.html which has the following structure:
<div id = "profile">
<h3>Profilinformationen</h3>
<form>
<fieldset>
<label id = "usernameLabel">Username:</label>
<input type = "text" id="usernameText" value = "<%= user.user.username %>" />
<br>
</fieldset>
</form>
To get the the attributes of the user variable, you have to initialize a user variable in your routing.js (called index.js in my case). This looks like
app.get('/profile', auth, function(request, response) {
response.render('pages/profile', {
user : request.user
});
});
I am using mongoose for my object model:

password : String
}
});

I know this is really old and most of the folks have already answered it right. Here are at least two ways you can find out the gradle version (not the gradle plugin version) by selecting one of the following on project tab on left:
Use a for

keys = ['firstKey', 'secondKey', 'thirdKey']
for key in keys:
myDictionary.get(key)
or a list comprehension:
[myDictionary.get(key) for key in keys]

If none of these (well, except the one that throws an exception) work on your computer, I don't think that the problem lies in the code, but in the environment. If that is the case, I would try one (or both) of the following:
You can try by adding this line
card_view:cardUseCompatPadding="true"
The Whole code will seems like this
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_margin="5dp"
android:orientation="horizontal"
card_view:cardUseCompatPadding="true"
card_view:cardCornerRadius="5dp">
</android.support.v7.widget.CardView
Just wrap your WebElement into Select Object as shown below
Select dropdown = new Select(driver.findElement(By.id("identifier")));
Once this is done you can select the required value in 3 ways. Consider an HTML file like this
<html>
<body>
<select id = "designation">
<option value = "MD">MD</option>
<option value = "prog"> Programmer </option>
<option value = "CEO"> CEO </option>
</option>
</select>
<body>
</html>
Now to identify dropdown do
Select dropdown = new Select(driver.findElement(By.id("designation")));
To select its option say 'Programmer' you can do
dropdown.selectByVisibleText("Programmer ");
or
dropdown.selectByIndex(1);
or
dropdown.selectByValue("prog");
Happy Coding :)
how about using IN
DELETE FROM tableName
WHERE ID IN (1,2) -- add as many ID as you want.
Use this code
((RadioButton)findViewById(R.id.radio3)).setChecked(true);
mistake -> don't forget to give () for whole before setChecked() -> If u forget to do that setChecked() is not available for this radio button
Here are the steps to edit the commit message of a previous commit (which is not the most recent commit) using SourceTree for Windows version 1.5.2.0:
Select the commit immediately before the commit that you want to edit. For example, if I want to edit the commit with message "FOOBAR!" then I need to select the commit that comes right before it:
Right-click on the selected commit and click Rebase children...interactively
:
Select the commit that you want to edit, then click Edit Message
at the
bottom. In this case, I'm selecting the commit with the message "FOOBAR!":
Edit the commit message, and then click OK
. In my example, I've added
"SHAZBOT! SKADOOSH!"
When you return to interactive rebase window, click on OK
to finish the
rebase:
At this point, you'll need to force-push your new changes since you've rebased commits that you've already pushed. However, the current 1.5.2.0 version of SourceTree for Windows does not allow you to force-push through the GUI, so you'll need to use Git from the command line anyways in order to do that.
Click Terminal
from the GUI to open up a terminal.
From the terminal force-push with the following command,
git push origin <branch> -f
where <branch>
is the name of the branch that you want to push, and -f
means
to force the push. The force push will overwrite your commits on your
remote repo, but that's OK in your case since you said that you're not sharing
your repo with other people.
That's it! You're done!
r
opens for reading, whereas r+
opens for reading and writing. The b
is for binary.
This is spelled out in the documentation:
The most commonly-used values of mode are
'r'
for reading,'w'
for writing (truncating the file if it already exists), and'a'
for appending (which on some Unix systems means that all writes append to the end of the file regardless of the current seek position). If mode is omitted, it defaults to'r'
. The default is to use text mode, which may convert'\n'
characters to a platform-specific representation on writing and back on reading. Thus, when opening a binary file, you should append'b'
to the mode value to open the file in binary mode, which will improve portability. (Appending'b'
is useful even on systems that don’t treat binary and text files differently, where it serves as documentation.) See below for more possible values of mode.Modes
'r+'
,'w+'
and'a+'
open the file for updating (note that'w+'
truncates the file). Append'b'
to the mode to open the file in binary mode, on systems that differentiate between binary and text files; on systems that don’t have this distinction, adding the'b'
has no effect.
I had the same issue. Sometimes this happens if your MySQL service is turned down.
So you have to start it:
sudo service mysql start
I also added
.modal { position: absolute; }
to the stylesheet to allow the dialog to scroll, but if the user has moved down to the bottom of a long page the modal can end up hidden off the top of the visible area.
I understand this is no longer an issue in bootstrap 3, but looking for a relatively quick fix until we upgrade I ended up with the above plus calling the following before opening the modal
$('.modal').css('top', $(document).scrollTop() + 50);
Seems to be happy in FireFox, Chrome, IE10 8 & 7 (the browsers I had to hand)
In addition to previously provided answers, one option is to follow the 'localhost exception' approach to create the first user if your db is already started with access control (--auth
switch). In order to do that, you need to have localhost access to the server and then run:
mongo
use admin
db.createUser(
{
user: "user_name",
pwd: "user_pass",
roles: [
{ role: "userAdminAnyDatabase", db: "admin" },
{ role: "readWriteAnyDatabase", db: "admin" },
{ role: "dbAdminAnyDatabase", db: "admin" }
]
})
As stated in MongoDB documentation:
The localhost exception allows you to enable access control and then create the first user in the system. With the localhost exception, after you enable access control, connect to the localhost interface and create the first user in the admin database. The first user must have privileges to create other users, such as a user with the userAdmin or userAdminAnyDatabase role. Connections using the localhost exception only have access to create the first user on the admin database.
Here is the link to that section of the docs.

In both Python 2 and 3, using the module pathlib2:
import posixpath # to generate unix paths
from pathlib2 import PurePath, PureWindowsPath, PurePosixPath
def path2unix(path, nojoin=True, fromwinpath=False):
"""From a path given in any format, converts to posix path format
fromwinpath=True forces the input path to be recognized as a Windows path (useful on Unix machines to unit test Windows paths)"""
if not path:
return path
if fromwinpath:
pathparts = list(PureWindowsPath(path).parts)
else:
pathparts = list(PurePath(path).parts)
if nojoin:
return pathparts
else:
return posixpath.join(*pathparts)
Usage:
In [9]: path2unix('lala/lolo/haha.dat')
Out[9]: ['lala', 'lolo', 'haha.dat']
In [10]: path2unix(r'C:\lala/lolo/haha.dat')
Out[10]: ['C:\\', 'lala', 'lolo', 'haha.dat']
In [11]: path2unix(r'C:\lala/lolo/haha.dat') # works even with malformatted cases mixing both Windows and Linux path separators
Out[11]: ['C:\\', 'lala', 'lolo', 'haha.dat']
With your testcase:
In [12]: testcase = paths = ['a/b/c/', 'a/b/c', '\\a\\b\\c', '\\a\\b\\c\\', 'a\\b\\c',
...: ... 'a/b/../../a/b/c/', 'a/b/../../a/b/c']
In [14]: for t in testcase:
...: print(path2unix(t)[-1])
...:
...:
c
c
c
c
c
c
c
The idea here is to convert all paths into the unified internal representation of pathlib2
, with different decoders depending on the platform. Fortunately, pathlib2
includes a generic decoder called PurePath
that should work on any path. In case this does not work, you can force the recognition of windows path using fromwinpath=True
. This will split the input string into parts, the last one is the leaf you are looking for, hence the path2unix(t)[-1]
.
If the argument nojoin=False
, the path will be joined back, so that the output is simply the input string converted to a Unix format, which can be useful to compare subpaths across platforms.
I have implemented MultipartReader NuGet package for ASP.NET 4 for reading multipart form data. It is based on Multipart Form Data Parser, but it supports more than one file.
Do this: Step 1: Your String
String str = ";;;;;;\n" +
"Name, number, address;;;;;;\n" +
"01.01.12-16.02.12;;;;;;\n" +
";;;;;;\n" +
";;;;;;";
Step 2: Just replace all "\n" with "%n" the result looks like this
String str = ";;;;;;%n" +
"Name, number, address;;;;;;%n" +
"01.01.12-16.02.12;;;;;;%n" +
";;;;;;%n" +
";;;;;;";
Notice I've just put "%n" in place of "\n"
Step 3: Now simply call format()
str=String.format(str);
That's all you have to do.
For file operations, Python uses the operating system's default buffering unless you configure it do otherwise. You can specify a buffer size, unbuffered, or line buffered.
For example, the open function takes a buffer size argument.
http://docs.python.org/library/functions.html#open
"The optional buffering argument specifies the file’s desired buffer size:"
code:
bufsize = 0
f = open('file.txt', 'w', buffering=bufsize)
Using dtype
will give you desired column's data type:
dataframe['column1'].dtype
if you want to know data types of all the column at once, you can use plural of dtype
as dtypes:
dataframe.dtypes
There is no built-in formula in excel, you have to add a vb script and permanently save it with your MS. Excel's installation as Add-In.

The last part of the error message you quoted states:
...with ("checkPermission") or explicitly handle a potential "SecurityException"
A much quicker/simpler way of checking if you have permissions is to surround your code with try { ... } catch (SecurityException e) { [insert error handling code here] }
. If you have permissions, the 'try' part will execute, if you don't, the 'catch' part will.

Unix
The commands env, set, and printenv display all environment variables and their values. env and set are also used to set environment variables and are often incorporated directly into the shell. printenv can also be used to print a single variable by giving that variable name as the sole argument to the command.
In Unix, the following commands can also be used, but are often dependent on a certain shell.
export VARIABLE=value # for Bourne, bash, and related shells
setenv VARIABLE value # for csh and related shells

Further note: Terminology in discussing R can be crucial and sometimes tricky. Using the term "table" to refer to that structure leaves open the possibility that it was either a 'table'-classed, or a 'matrix'-classed, or a 'data.frame'-classed object. The answer above would succeed with any of them, while @BenBolker's suggestion below would only succeed with a 'data.frame'-classed object.
I am unrepentant in my phrasing despite the recent downvote. There is a ton of free introductory material for beginners in R: https://cran.r-project.org/other-docs.html
Short answers:
Q1: Yes.
Q2: Doesn't matter which you use.
Long answer:
A select ... for update
will (as it implies) select certain rows but also lock them as if they have already been updated by the current transaction (or as if the identity update had been performed). This allows you to update them again in the current transaction and then commit, without another transaction being able to modify these rows in any way.
Another way of looking at it, it is as if the following two statements are executed atomically:
select * from my_table where my_condition;
update my_table set my_column = my_column where my_condition;
Since the rows affected by my_condition
are locked, no other transaction can modify them in any way, and hence, transaction isolation level makes no difference here.
Note also that transaction isolation level is independent of locking: setting a different isolation level doesn't allow you to get around locking and update rows in a different transaction that are locked by your transaction.
What transaction isolation levels do guarantee (at different levels) is the consistency of data while transactions are in progress.

If Apache was installed using NSIS installer it should have left an uninstaller. You should search inside Apache installation directory for executable named unistaller.exe
or something like that. NSIS uninstallers support /S
flag by default for silent uninstall. So you can run something like "C:\Program Files\<Apache installation dir here>\uninstaller.exe" /S
From NSIS documentation:
3.2.1 Common Options
/NCRC disables the CRC check, unless CRCCheck force was used in the script. /S runs the installer or uninstaller silently. See section 4.12 for more information. /D sets the default installation directory ($INSTDIR), overriding InstallDir and InstallDirRegKey. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported.
I was able to get my similar command working using the following approach:
msdeploy.exe -verb=sync "-source=dbFullSql=Server=THESERVER;Database=myDB;UID=sa;Pwd=saPwd" -dest=dbFullSql=c:\temp\test.sql
For your command (not that it helps much now), things would look something like this:
msdeploy.exe -verb=sync "-source=dbfullsql=Server=mysource;Trusted_Connection=false;UID=sa;Pwd=sapass!;Database=mydb;" "-dest=dbfullsql=Server=mydestsource;Trusted_Connection=false;UID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass
The key points are:
I didn't try adding the "computername" part at the end of the command line, but hopefully this info will help others reading this now get closer to their desired result.
Of course! jQuery is just a library that utilizes javascript after all.
You can use document.getElementById to get the element in question, then change its height accordingly, through element.style.height.
elementToChange = document.getElementById('collapseableEl');
elementToChange.style.height = '100%';
Wrap that up in a neat little function that caters for toggling back and forth and you have yourself a solution.
If you want to do this in a robust way that works for every possible command line argument (values with spaces, values with newlines, values with literal quote characters, non-printable values, values with glob characters, etc), it gets a bit more interesting.
To write to a file, given an array of arguments:
printf '%s\0' "${arguments[@]}" >file
...replace with "argument one"
, "argument two"
, etc. as appropriate.
To read from that file and use its contents (in bash, ksh93, or another recent shell with arrays):
declare -a args=()
while IFS='' read -r -d '' item; do
args+=( "$item" )
done <file
run_your_command "${args[@]}"
To read from that file and use its contents (in a shell without arrays; note that this will overwrite your local command-line argument list, and is thus best done inside of a function, such that you're overwriting the function's arguments and not the global list):
set --
while IFS='' read -r -d '' item; do
set -- "$@" "$item"
done <file
run_your_command "$@"
Note that -d
(allowing a different end-of-line delimiter to be used) is a non-POSIX extension, and a shell without arrays may also not support it. Should that be the case, you may need to use a non-shell language to transform the NUL-delimited content into an eval
-safe form:

#' keep rows that have a certain number (range) of NAs anywhere/somewhere and delete others
#' @param df a data frame
#' @param col restrict to the columns where you would like to search for NA; eg, 3, c(3), 2:5, "place", c("place","age")
#' \cr default is NULL, search for all columns
#' @param n integer or vector, 0, c(3,5), number/range of NAs allowed.
#' \cr If a number, the exact number of NAs kept
#' \cr Range includes both ends 3<=n<=5
#' \cr Range could be -Inf, Inf
#' @return returns a new df with rows that have NA(s) removed
#' @export
ez.na.keep = function(df, col=NULL, n=0){
if (!is.null(col)) {

I was so exasperated by many misleading articles and answers that I wrote my own RSS reader: https://gouessej.wordpress.com/2020/06/28/comment-creer-un-lecteur-rss-en-javascript-how-to-create-a-rss-reader-in-javascript/
You can use AJAX requests to fetch the RSS files but it will work if and only if you use a CORS proxy. I'll try to write my own CORS proxy to give you a more robust solution. In the meantime, it works, I deployed it on my server under Debian Linux.
My solution doesn't use JQuery, I use only plain Javascript standard APIs with no third party libraries and it's supposed to work even with Microsoft Internet Explorer 11.
for (int i = 1; i*i <= num; ++i)
{
if (num % i == 0)
cout << i << endl;
if (num/i!=i)
cout << num/i << endl;
}
I use SourceTree git client, and I see that their initial commit/push command is:
git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags --set-upstream origin master:master
For your code
var mytextvalue = document.getElementById("mytext");
mytextvalue
will contain null
if you have a document.write()
statement before this code. So remove the document.write
statement and you should get a proper text object in the variable mytextvalue
.
This is caused by document.write
changing the document.
Maybe :active
over :focus
with :hover
will help!
Try
button {
background:lime;
}
button:hover {
background:green;
}
button:focus {
background:gray;
}
button:active {
background:red;
}
Then:
<button onkeydown="alerted_of_key_pressed()" id="button" title="Test button" href="#button">Demo</button>
Then:
<!--JAVASCRIPT-->
<script>
function alerted_of_key_pressed() { alert("You pressed a key when hovering over this button.") }
</script>
Sorry about that last one. :) I was just showing you a cool function! Wait... did I just emphasize a code block? This is cool!!!
There is a tool localfont.com to help you download all font variants. It as well generates the corresponding CSS for implementation. deprecated
localfont is down. Instead, as Damir suggests, you can use google-webfonts-helper
You can change the case of String before using it, like this
String name1 = fname.getText().toString().toLowerCase();
String name2 = sname.getText().toString().toLowerCase();
Then continue with rest operation.
If it is possible to change the sequence of the lines you could do:
^(.*\r?\n)\1+
How it works: The sorting puts the duplicates behind each other. The find matches a line ^(.*\r?\n)
and captures the line in \1
then it continues and tries to find \1
one or more times (+
) behind the first match. Such a block of duplicates (if it exists) is replaced with nothing.
The \r?\n
should deal nicely with Windows and Unix lineendings.
I previously had the same issue, but I realized that I didn't include the "app.js
" (the main application) inside my main page (index.html
).
So even when you include all the dependencies required by AngularJS, you might end up with that error in the console. So always make sure to include the necessary files inside your main page and you shouldn't have that issue.
Hope this helps.
<textarea rows="4" cols="50"></textarea>
It is equivalent to:
textarea {
height: 4em;
width: 50em;
}
where 1em is equivalent to the current font size, thus make the text area 50 chars wide. see here.
Another possible solution that doesn't require to add any extra markup is to add some dynamic margin to separate the elements.
In the case of the example, this can be done with the help of calc()
, just adding margin-left
and margin-right
to the 3n+2 element (2, 5, 8)
.item:nth-child(3n+2) {
background: silver;
margin: 10px calc(50% - 175px);
}

In python you would use a dictionary.
It is a very important type in python and often used.
You can create one easily by
name = {}
Dictionaries have many methods:
# add entries:
>>> name['first'] = 'John'
>>> name['second'] = 'Doe'
>>> name
{'first': 'John', 'second': 'Doe'}
# you can store all objects and datatypes as value in a dictionary
# as key you can use all objects and datatypes that are hashable
>>> name['list'] = ['list', 'inside', 'dict']
>>> name[1] = 1
>>> name
{'first': 'John', 'second': 'Doe', 1: 1, 'list': ['list', 'inside', 'dict']}
You can not influence the order of a dict.
This might seem like overkill, but if in another case you were trying to load a canvas from js (like I am doing), you could use a setInterval function and an if statement to constantly check if the canvas has loaded.
//set up the interval
var thisInterval = setInterval(function{
//this if statment checks if the id "thisCanvas" is linked to something
if(document.getElementById("thisCanvas") != null){
//do what you want
//clearInterval() will remove the interval if you have given your interval a name.
clearInterval(thisInterval)
}
//the 500 means that you will loop through this every 500 milliseconds (1/2 a second)
},500)
(In this example the canvas I am trying to load has an id of "thisCanvas")
You can use PowerShell to generate a self-signed certificate with the new-selfsignedcertificate cmdlet:
New-SelfSignedCertificate -DnsName "localhost" -CertStoreLocation "cert:\LocalMachine\My"

No, Java doesn't support user-defined operator overloading. The only aspect of Java which comes close to "custom" operator overloading is the handling of + for strings, which either results in compile-time concatenation of constants or execution-time concatenation using StringBuilder/StringBuffer. You can't define your own operators which act in the same way though.
For a Java-like (and JVM-based) language which does support operator overloading, you could look at Kotlin or Groovy. Alternatively, you might find luck with a Java compiler plugin solution.
Simply just divide the numbers, it gives yuh the decimal format and even the numerical format. using S<->D
For example: 11/3 gives you 3.666667 and 3 2/3 (Swap using S<->D). Here the '2' from 2/3 is your mod value.
Similarly 18/6 gives you 14.833333 and 14 5/6 (Swap using S<->D). Here the '5' from 5/6 is your mod value.
"If a huge integer isn't recalled, you recall this mnemonic."
Now count the letters in each word.
I think the issue is that you've got it just a little upside down.
public class AuroraClient : IAuroraClient
{
private readonly HttpClient _client;
public AuroraClient() : this(new HttpClientHandler())
{
}
public AuroraClient(HttpMessageHandler messageHandler)
{
_client = new HttpClient(messageHandler);
}
}
If you look at the class above, I think this is what you want. Microsoft recommends keeping the client alive for optimal performance, so this type of structure allows you to do that. Also the HttpMessageHandler is an abstract class and therefore mockable. Your test method would then look like this:
[TestMethod]
public void TestMethod1()
{
// Arrange
var mockMessageHandler = new Mock<HttpMessageHandler>();
// Set up your mock behavior here
var auroraClient = new AuroraClient(mockMessageHandler.Object);
// Act
// Assert
}
This allows you to test your logic while mocking the HttpClient's behavior.
Sorry guys, after writing this and trying it myself, I realized that you can't mock the protected methods on the HttpMessageHandler. I subsequently added the following code to allow for injection of a proper mock.
public interface IMockHttpMessageHandler
{
Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken);
}
public class MockHttpMessageHandler : HttpMessageHandler
{
private readonly IMockHttpMessageHandler _realMockHandler;
public MockHttpMessageHandler(IMockHttpMessageHandler realMockHandler)
{
_realMockHandler = realMockHandler;
}
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
return await _realMockHandler.SendAsync(request, cancellationToken);
}
}
The tests written with this then look something like the following:
[TestMethod]
public async Task GetProductsReturnsDeserializedXmlXopData()
{
// Arrange
var mockMessageHandler = new Mock<IMockHttpMessageHandler>();
// Set up Mock behavior here.
var client = new AuroraClient(new MockHttpMessageHandler(mockMessageHandler.Object));
// Act
// Assert
}
After some years with node, I can say that there are no conventions for the directory/file structure. However most (professional) express applications use a setup like:
/
/bin - scripts, helpers, binaries
/lib - your application
/config - your configuration
/public - your public files
/test - your tests
An example which uses this setup is nodejs-starter.
I personally changed this setup to:
/
/etc - contains configuration
/app - front-end javascript files
/config - loads config
/models - loads models
/bin - helper scripts
/lib - back-end express files
/config - loads config to app.settings
/models - loads mongoose models
/routes - sets up app.get('..')...
/srv - contains public files
/usr - contains templates
/test - contains test files
In my opinion, the latter matches better with the Unix-style directory structure (whereas the former mixes this up a bit).
I also like this pattern to separate files:
lib/index.js
var http = require('http');
var express = require('express');
var app = express();
app.server = http.createServer(app);
require('./config')(app);
require('./models')(app);
require('./routes')(app);
app.server.listen(app.settings.port);
module.exports = app;
lib/static/index.js
var express = require('express');
module.exports = function(app) {
app.use(express.static(app.settings.static.path));
};
This allows decoupling neatly all source code without having to bother dependencies. A really good solution for fighting nasty Javascript. A real-world example is nearby which uses this setup.
Update (filenames):
Regarding filenames most common are short, lowercase filenames. If your file can only be described with two words most JavaScript projects use an underscore as the delimiter.
Update (variables):
Regarding variables, the same "rules" apply as for filenames. Prototypes or classes, however, should use camelCase.
Update (styleguides):
If you want to print the last 10 lines, use
tail(dataset, 10)
for the first 10, you could also do
head(dataset, 10)
You can simply use the new Java 8 Stream
s but you have to work with int
.
The stream
method of the utility class Arrays
gives you an IntStream
on which you can use the min
method. You can also do max
, sum
, average
,...
The getAsInt
method is used to get the value from the OptionalInt
import java.util.Arrays;
public class Test {
public static void main(String[] args){
int[] tab = {12, 1, 21, 8};
int min = Arrays.stream(tab).min().getAsInt();
int max = Arrays.stream(tab).max().getAsInt();
System.out.println("Min = " + min);
System.out.println("Max = " + max)
}
}
==UPDATE==
If execution time is important and you want to go through the data only once you can use the summaryStatistics()
method like this
import java.util.Arrays;
import java.util.IntSummaryStatistics;
public class SOTest {
public static void main(String[] args){
int[] tab = {12, 1, 21, 8};
IntSummaryStatistics stat = Arrays.stream(tab).summaryStatistics();
int min = stat.getMin();
int max = stat.getMax();
System.out.println("Min = " + min);
System.out.println("Max = " + max);
}
}
This approach can give better performance than classical loop because the summaryStatistics
method is a reduction operation and it allows parallelization.
Alternatively, you can also parse a standard markdown document (without code blocks per se) on the fly by the markdownreports package.
Have a look at this jQuery plugin from OvalPixels.
It may do the trick.
I recently had to do something similar, this is what I came up with:
/**
* Returns a date set to the begining of the month
*
* @param {Date} myDate
* @returns {Date}
*/
function beginningOfMonth(myDate){
let date = new Date(myDate);
date.setDate(1)
date.setHours(0);
date.setMinutes(0);
date.setSeconds(0);
return date;
}
/**
* Returns a date set to the end of the month
*
* @param {Date} myDate
* @returns {Date}
*/
function endOfMonth(myDate){
let date = new Date(myDate);
date.setMonth(date.getMonth() +1)
date.setDate(0);
date.setHours(23);
date.setMinutes(59);
date.setSeconds(59);
return date;
}
Pass it in a date, and it will return a date set to either the beginning of the month, or the end of the month.
The begninngOfMonth
function is fairly self-explanatory, but what's going in in the endOfMonth
function is that I'm incrementing the month to the next month, and then using setDate(0)
to roll back the day to the last day of the previous month which is a part of the setDate spec:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/setDate https://www.w3schools.com/jsref/jsref_setdate.asp
I then set the hour/minutes/seconds to the end of the day, so that if you're using some kind of API that is expecting a date range you'll be able to capture the entirety of that last day. That part might go beyond what the original post is asking for but it could help someone else looking for a similar solution.
Edit: You can also go the extra mile and set milliseconds with setMilliseconds()
if you want to be extra precise.
Left Click on chart. «PivotTable Field List» will appear on right. On the right down quarter of PivotTable Field List (S Values), you see the names of the legends. Left Click on the legend name. Left Click on the «Value field settings». At the top there is «Source Name». You can’t change it. Below there is «Custom Name». Change the Custom Name as you wish. Now the legend name on the chart has the new name you gave.
I've just had the same issue - for me Privacy Badger on Firefox was the issue - not adblocker. Posting for posterity
If you only need to execute only one command all by itself and no wait needed, you should try "cmd /c", this works for me!
cmd /c start iexplore "http://your/url.html"
cmd /c means executing a command and then exit.
You can learn the functions of your switches by typing in your command prompt
anycmd /?
If you use the WEB API with Claims, you can use this:
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class AutorizeCompanyAttribute: AuthorizationFilterAttribute
{
public string Company { get; set; }
public override void OnAuthorization(HttpActionContext actionContext)
{
var claims = ((ClaimsIdentity)Thread.CurrentPrincipal.Identity);
var claim = claims.Claims.Where(x => x.Type == "Company").FirstOrDefault();
string privilegeLevels = string.Join("", claim.Value);
if (privilegeLevels.Contains(this.Company)==false)
{
actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized, "Usuario de Empresa No Autorizado");
}
}
}
[HttpGet]
[AutorizeCompany(Company = "MyCompany")]
[Authorize(Roles ="SuperAdmin")]
public IEnumerable MyAction()
{....
}
NOTE: The original answer below should work for any version of Visual Studio up through Visual Studio 2012. Visual Studio 2013 does not appear to have a Test Results window any more. Instead, if you need test-specific output you can use @Stretch's suggestion of Trace.Write()
to write output to the Output window.
The Console.Write
method does not write to the "console" -- it writes to whatever is hooked up to the standard output handle for the running process. Similarly, Console.Read
reads input from whatever is hooked up to the standard input.
When you run a unit test through Visual Studio 2010, standard output is redirected by the test harness and stored as part of the test output. You can see this by right-clicking the Test Results window and adding the column named "Output (StdOut)" to the display. This will show anything that was written to standard output.
You could manually open a console window, using P/Invoke as sinni800 says. From reading the AllocConsole
documentation, it appears that the function will reset stdin
and stdout
handles to point to the new console window. (I'm not 100% sure about that; it seems kind of wrong to me if I've already redirected stdout
for Windows to steal it from me, but I haven't tried.)
In general, though, I think it's a bad idea; if all you want to use the console for is to dump more information about your unit test, the output is there for you. Keep using Console.WriteLine
the way you are, and check the output results in the Test Results window when it's done.
If you need to clear the values of $_SESSION
, set the array equal to an empty array:
$_SESSION = array();
Of course, you can't access the values of $_SESSION
on another page once you call session_destroy
, so it doesn't matter that much.
Try the following:
session_destroy();
$_SESSION = array(); // Clears the $_SESSION variable
I think you have a conceptual problem here. To say "I tried set height:100% on iframe, the result is quite close but the iframe tried to fill the whole page", well, when has "100%" not been equal to "whole"?
You have asked the iframe to fill the entire height of its container (which is the body) but unfortunately it has a block level sibling in the <div> above which you've asked to be 30px big. So the parent container total is now being asked to size to 100% + 30px > 100%! Hence scrollbars.
What I think you mean is that you would like the iframe to consume what's left like frames and table cells can, i.e. height="*". IIRC this doesn't exist.
Unfortunately to the best of my knowledge there is no way to effectively mix/calculate/subtract absolute and relative units either, so I think you're reduced to two options:
Absolutely position your div, which will take it out of the container so the iframe alone will consume it's containers height. This leaves you with all manner of other problems though, but perhaps for what you're doing opacity or alignment would be ok.
Alternatively you need to specify a % height for the div and reduce the height of the iframe by that much. If the absolute height is really that important you'll need to apply that to a child element of the div instead.
You have to tell the system what information to log and where to put the info. Logging is configured in the /etc/rsyslog.conf
file, then restart rsyslog to load the new config. The default logging rules are usually in a /etc/rsyslog.d/50-default.conf
file.
I post a solution extending the image control and using the Gif Decoder. The gif decoder has a frames property. I animate the FrameIndex
property. The event ChangingFrameIndex
changes the source property to the frame corresponding to the FrameIndex
(that is in the decoder). I guess that the gif has 10 frames per second.
class GifImage : Image
{
private bool _isInitialized;
private GifBitmapDecoder _gifDecoder;
private Int32Animation _animation;
public int FrameIndex
{
get { return (int)GetValue(FrameIndexProperty); }
set { SetValue(FrameIndexProperty, value); }
}
private void Initialize()
{
_gifDecoder = new GifBitmapDecoder(new Uri("pack://application:,,," + this.GifSource), BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
_animation = new Int32Animation(0, _gifDecoder.Frames.Count - 1, new Duration(new TimeSpan(0, 0, 0, _gifDecoder.Frames.Count / 10, (int)((_gifDecoder.Frames.Count / 10.0 - _gifDecoder.Frames.Count / 10) * 1000))));
_animation.RepeatBehavior = RepeatBehavior.Forever;
this.Source = _gifDecoder.Frames[0];
_isInitialized = true;
}
static GifImage()
{
VisibilityProperty.OverrideMetadata(typeof (GifImage),
new FrameworkPropertyMetadata(VisibilityPropertyChanged));
}
private static void VisibilityPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
if ((Visibility)e.NewValue == Visibility.Visible)
{
((GifImage)sender).StartAnimation();
}
else
{
((GifImage)sender).StopAnimation();
}
}
public static readonly DependencyProperty FrameIndexProperty =
DependencyProperty.Register("FrameIndex", typeof(int), typeof(GifImage), new UIPropertyMetadata(0, new PropertyChangedCallback(ChangingFrameIndex)));
static void ChangingFrameIndex(DependencyObject obj, DependencyPropertyChangedEventArgs ev)
{
var gifImage = obj as GifImage;
gifImage.Source = gifImage._gifDecoder.Frames[(int)ev.NewValue];
}
/// <summary>
/// Defines whether the animation starts on it's own
/// </summary>
public bool AutoStart
{
get { return (bool)GetValue(AutoStartProperty); }
set { SetValue(AutoStartProperty, value); }
}
public static readonly DependencyProperty AutoStartProperty =
DependencyProperty.Register("AutoStart", typeof(bool), typeof(GifImage), new UIPropertyMetadata(false, AutoStartPropertyChanged));
private static void AutoStartPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
if ((bool)e.NewValue)
(sender as GifImage).StartAnimation();
}
public string GifSource
{
get { return (string)GetValue(GifSourceProperty); }
set { SetValue(GifSourceProperty, value); }
}
public static readonly DependencyProperty GifSourceProperty =
DependencyProperty.Register("GifSource", typeof(string), typeof(GifImage), new UIPropertyMetadata(string.Empty, GifSourcePropertyChanged));
private static void GifSourcePropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
(sender as GifImage).Initialize();
}
/// <summary>
/// Starts the animation
/// </summary>
public void StartAnimation()
{
if (!_isInitialized)
this.Initialize();
BeginAnimation(FrameIndexProperty, _animation);
}
/// <summary>
/// Stops the animation
/// </summary>
public void StopAnimation()
{
BeginAnimation(FrameIndexProperty, null);
}
}
Usage example (XAML):
<controls:GifImage x:Name="gifImage" Stretch="None" GifSource="/SomeImage.gif" AutoStart="True" />
We are already in 21st century!! Don't try to implement the already existing data structures. Try to use the existing data structures.
Use STL or Boost library
Use Intent Preference if you are using preference xml screen or you if you are using you custom screen then the code would be like below
intentClearCookies = getPreferenceManager().createPreferenceScreen(this);
Intent clearcookies = new Intent(PopupPostPref.this, ClearCookies.class);
intentClearCookies.setIntent(clearcookies);
intentClearCookies.setTitle(R.string.ClearCookies);
intentClearCookies.setEnabled(true);
launchPrefCat.addPreference(intentClearCookies);
And then Create Activity Class somewhat like below, As different people as different approach you can use any approach you like this is just an example.
public class ClearCookies extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
showDialog();
}
/**
* @throws NotFoundException
*/
private void showDialog() throws NotFoundException {
new AlertDialog.Builder(this)
.setTitle(getResources().getString(R.string.ClearCookies))
.setMessage(
getResources().getString(R.string.ClearCookieQuestion))
.setIcon(
getResources().getDrawable(
android.R.drawable.ic_dialog_alert))
.setPositiveButton(
getResources().getString(R.string.PostiveYesButton),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
//Do Something Here
}
})
.setNegativeButton(
getResources().getString(R.string.NegativeNoButton),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
//Do Something Here
}
}).show();
}}
As told before there are number of ways doing this. this is one of the way you can do your task, please accept the answer if you feel that you have got it what you wanted.
Sorry the answer of George Bailey does work very fine when you want absolutely remove the node from your machine.
This answer is referred from : @tedeh https://github.com/nodesource/distributions/issues/486
If you wanna install a new version of node you have to use the code below
sudo rm -rf /var/cache/yum
sudo yum remove -y nodejs
sudo rm /etc/yum.repos.d/nodesource*
sudo yum clean all
And add new nodejs version to "yum" an new version of node
#using this command for Node version 8
curl --silent --location https://rpm.nodesource.com/setup_8.x | sudo bash -
#using this command for Node version 10
curl --silent --location https://rpm.nodesource.com/setup_10.x | sudo bash -
Install nodejs
sudo yum -y install nodejs
I hope it gonna help you guy!!!
If you don't want to convert.Just use;
bool _status = status == "1" ? true : false;
Perhaps you will return the values as you want.
Updated for Swift 3 and above:
//1. Create the alert controller.
let alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .alert)
//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in
textField.text = "Some default text"
}
// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
let textField = alert.textFields![0] // Force unwrapping because we know it exists.
print("Text field: \(textField.text)")
}))
// 4. Present the alert.
self.present(alert, animated: true, completion: nil)
Swift 2.x
Assuming you want an action alert on iOS:
//1. Create the alert controller.
var alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .Alert)
//2. Add the text field. You can configure it however you need.
alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in
textField.text = "Some default text."
})
//3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: { [weak alert] (action) -> Void in
let textField = alert.textFields![0] as UITextField
println("Text field: \(textField.text)")
}))
// 4. Present the alert.
self.presentViewController(alert, animated: true, completion: nil)
Do you know if the renew button only appeared when the profile expired? I've a profile that will expire soon, but no "renew" button is shown at the moment.
Just read elsewhere that apparently this is the case.
Just my 2 cents. I would create a solution which records exactly what changed, very similar to transient's solution.
My ChangesTable would simple be:
DateTime | WhoChanged | TableName | Action | ID |FieldName | OldValue
1) When an entire row is changed in the main table, lots of entries will go into this table, BUT that is very unlikely, so not a big problem (people are usually only changing one thing) 2) OldVaue (and NewValue if you want) have to be some sort of epic "anytype" since it could be any data, there might be a way to do this with RAW types or just using JSON strings to convert in and out.
Minimum data usage, stores everything you need and can be used for all tables at once. I'm researching this myself right now, but this might end up being the way I go.
For Create and Delete, just the row ID, no fields needed. On delete a flag on the main table (active?) would be good.
Use an relative path to the root of your site, for example:
If clock.js is on http://domain.com/javascript/clock.js
Include :
<script language="JavaScript" src="/javascript/clock.js"></script>
If it's on your domain root directory:
<script language="JavaScript" src="/clock.js"></script>
As Commodore Jaeger alluded to, I don't think any of the other answers actually answer this question; the question asks how to repeat a string, not a character.
While the answer given by Commodore is correct, it is quite inefficient. Here is a faster implementation, the idea is to minimise copying operations and memory allocations by first exponentially growing the string:
#include <string>
#include <cstddef>
std::string repeat(std::string str, const std::size_t n)
{
if (n == 0) {
str.clear();
str.shrink_to_fit();
return str;
} else if (n == 1 || str.empty()) {
return str;
}
const auto period = str.size();
if (period == 1) {
str.append(n - 1, str.front());
return str;
}
str.reserve(period * n);
std::size_t m {2};
for (; m < n; m *= 2) str += str;
str.append(str.c_str(), (n - (m / 2)) * period);
return str;
}
We can also define an operator*
to get something closer to the Python version:
#include <utility>
std::string operator*(std::string str, std::size_t n)
{
return repeat(std::move(str), n);
}
On my machine this is around 10x faster than the implementation given by Commodore, and about 2x faster than a naive 'append n - 1 times' solution.
Try to use GMT
instead of UTC
. They refer to the same time zone, yet the name GMT
is more common and might work.
In add_argument()
, type
is just a callable object that receives string and returns option value.
import ast
def arg_as_list(s):
v = ast.literal_eval(s)
if type(v) is not list:
raise argparse.ArgumentTypeError("Argument \"%s\" is not a list" % (s))
return v
def foo():
parser.add_argument("--list", type=arg_as_list, default=[],
help="List of values")
This will allow to:
$ ./tool --list "[1,2,3,4]"
Don't forget to create your migrations after writing the models
If using SQL Server, SqlBulkCopy.WriteToServer(DataTable)
Or also with SQL Server, you can write it to a .csv and use BULK INSERT
If using MySQL, you could write it to a .csv and use LOAD DATA INFILE
If using Oracle, you can use the array binding feature of ODP.NET
If SQLite:
Just use GetDate()
not Select GetDate()
DECLARE @LastChangeDate as date
SET @LastChangeDate = GETDATE()
but if it's SQL Server, you can also initialize in same step as declaration...
DECLARE @LastChangeDate date = getDate()
@Juri
If you add IntentFilters for your service, you are saying you want to expose your service to other applications, then it may be stopped unexpectedly by other applications.
You can also use includes
const isApple = ['iPhone', 'iPad', 'iPod', 'iPad Simulator', 'iPhone Simulator', 'iPod Simulator',].includes(navigator.platform)
If using integers as targets, makes sure they aren't symmetrical at 0.
I.e., don't use classes -1, 0, 1. Use instead 0, 1, 2.
Built on top of Wasim A.'s excellent idea to use serialization. The problem there was that the warning was also shown when the form was being submitted. This has been fixed here.
var isSubmitting = false
$(document).ready(function () {
$('form').submit(function(){
isSubmitting = true
})
$('form').data('initial-state', $('form').serialize());
$(window).on('beforeunload', function() {
if (!isSubmitting && $('form').serialize() != $('form').data('initial-state')){
return 'You have unsaved changes which will not be saved.'
}
});
})
It has been tested in Chrome and IE 11.
To reverse a string without using reversed
or [::-1]
, try something like:
def reverse(text):
# Container for reversed string
txet=""
# store the length of the string to be reversed
# account for indexes starting at 0
length = len(text)-1
# loop through the string in reverse and append each character
# deprecate the length index
while length>=0:
txet += "%s"%text[length]
length-=1
return txet
Your problem seems unclear. You say you want to remove "a character from a certain position" then go on to say you want to remove a particular character.
If you only need to remove the first character you would do:
s = ":dfa:sif:e"
fixed = s[1:]
If you want to remove a character at a particular position, you would do:
s = ":dfa:sif:e"
fixed = s[0:pos]+s[pos+1:]
If you need to remove a particular character, say ':', the first time it is encountered in a string then you would do:
s = ":dfa:sif:e"
fixed = ''.join(s.split(':', 1))
This one worked for me :
function validateForm(){
var z = document.forms["myForm"]["num"].value;
if(!/^[0-9]+$/.test(z)){
alert("Please only enter numeric characters only for your Age! (Allowed input:0-9)")
}
}
SELECT tab.*,
row_number() OVER () as rnum
FROM tab;
Here's the relevant section in the docs.
P.S. This, in fact, fully matches the answer in the referenced question.
Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.
To solve your requirement, here is the working solution -
First create your ViewModels in following way. PersonModel can have list of RoleModels.
public class PersonModel
{
public List<RoleModel> Roles { get; set; }
public string Name { get; set; }
}
public class RoleModel
{
public string RoleName { get; set;}
public string Description { get; set;}
}
Then have a index action which will be serving basic index view -
public ActionResult Index()
{
return View();
}
Index view will be having following JQuery AJAX POST operation -
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
$(function () {
$('#click1').click(function (e) {
var jsonObject = {
"Name" : "Rami",
"Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
};
$.ajax({
url: "@Url.Action("AddUser")",
type: "POST",
data: JSON.stringify(jsonObject),
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (response) {
alert(response.responseText);
},
success: function (response) {
alert(response);
}
});
});
});
</script>
<input type="button" value="click1" id="click1" />
Index action posts to AddUser action -
[HttpPost]
public ActionResult AddUser(PersonModel model)
{
if (model != null)
{
return Json("Success");
}
else
{
return Json("An Error Has occoured");
}
}
So now when the post happens you can get all the posted data in the model parameter of action.
Update:
For asp.net core, to get JSON data as your action parameter you should add the [FromBody]
attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController]
attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)
The above solutions missed out on where to keep your backup (.bak) file. This should do the trick. It worked for me.
With set of static imports, Guava solution can be very compact one-liner:
toString(getResource("foo.txt"), UTF_8);
The following imports are required:
import static com.google.common.io.Resources.getResource
import static com.google.common.io.Resources.toString
import static java.nio.charset.StandardCharsets.UTF_8
In TorpedoQuery it look like this
Entity from = from(Entity.class);
where(from.getCode()).in("Joe", "Bob");
Query<Entity> select = select(from);
An alternative, but a bit slower alternative is to do it over indexing.
np.isnan(data)[np.isnan(data) == False].size
In [30]: %timeit np.isnan(data)[np.isnan(data) == False].size
1 loops, best of 3: 498 ms per loop
The double use of np.isnan(data)
and the ==
operator might be a bit overkill and so I posted the answer only for completeness.

To understand Strong and Weak reference consider below example, suppose we have method named as displayLocalVariable.
-(void)displayLocalVariable
{
NSString myName = @"ABC";
NSLog(@"My name is = %@", myName);
}
In above method scope of myName variable is limited to displayLocalVariable method, once the method gets finished myName variable which is holding the string "ABC" will get deallocated from the memory.
Now what if we want to hold the myName variable value throughout our view controller life cycle. For this we can create the property named as username which will have Strong reference to the variable myName(see self.username = myName;
in below code), as below,
@interface LoginViewController ()
@property(nonatomic,strong) NSString* username;
@property(nonatomic,weak) NSString* dummyName;
- (void)displayLocalVariable;
@end
@implementation LoginViewController
- (void)viewDidLoad
{
[super viewDidLoad];
}
-(void)viewWillAppear:(BOOL)animated
{
[self displayLocalVariable];
}
- (void)displayLocalVariable
{
NSString myName = @"ABC";
NSLog(@"My name is = %@", myName);
self.username = myName;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
@end
Now in above code you can see myName has been assigned to self.username and self.username is having a strong reference(as we declared in interface using @property) to myName(indirectly it's having Strong reference to "ABC" string). Hence String myName will not get deallocated from memory till self.username is alive.
Now consider assigning myName to dummyName which is a Weak reference, self.dummyName = myName; Unlike Strong reference Weak will hold the myName only till there is Strong reference to myName. See below code to understand Weak reference,
-(void)displayLocalVariable
{
NSString myName = @"ABC";
NSLog(@"My name is = %@", myName);
self.dummyName = myName;
}
In above code there is Weak reference to myName(i.e. self.dummyName is having Weak reference to myName) but there is no Strong reference to myName, hence self.dummyName will not be able to hold the myName value.
Now again consider the below code,
-(void)displayLocalVariable
{
NSString myName = @"ABC";
NSLog(@"My name is = %@", myName);
self.username = myName;
self.dummyName = myName;
}
In above code self.username has a Strong reference to myName, hence self.dummyName will now have a value of myName even after method ends since myName has a Strong reference associated with it.
Now whenever we make a Strong reference to a variable it's retain count get increased by one and the variable will not get deallocated retain count reaches to 0.
Hope this helps.
In addition to the existing answer it is possible to set a default option as follows:
echo off
ECHO A current build of Test Harness exists.
set delBuild=n
set /p delBuild=Delete preexisting build [y/n] (default - %delBuild%)?:
This allows users to simply hit "Enter" if they want to enter the default.
for(n in 1:5) {
if(n==3) next # skip 3rd iteration and go to next iteration
cat(n)
}
Use forward declarations where you can. If a class declaration only uses a pointer or reference to a type, you can just forward declare it and include the header for the type in the implementation file.
For example:
// T.h
class Class2; // Forward declaration
class T {
public:
void doSomething(Class2 &c2);
private:
Class2 *m_Class2Ptr;
};
// T.cpp
#include "Class2.h"
void Class2::doSomething(Class2 &c2) {
// Whatever you want here
}
Fewer includes means far less work for the preprocessor if you do it enough.
Depends on if the form that the select is contained in has the method set to "get" or "post".
If <form method="get">
then the value of the select will be located in the super global array $_GET['taskOption']
.
If <form method="post">
then the value of the select will be located in the super global array $_POST['taskOption']
.
To store it into a variable you would:
$option = $_POST['taskOption']
A good place for more information would be the PHP manual: http://php.net/manual/en/tutorial.forms.php
JB hit the nail on the head. The only thing I can add is that Java 8 doesn't do pure parallel processing, it does paraquential. Yes I wrote the article and I've been doing F/J for thirty years so I do understand the issue.
That's a bit of informal terminology.
As far as Git is concerned, every other repository is just a remote.
Generally speaking, upstream is where you cloned from (the origin). Downstream is any project that integrates your work with other works.
The terms are not restricted to Git repositories.
For instance, Ubuntu is a Debian derivative, so Debian is upstream for Ubuntu.
In case others have a hard time making sense of this, I think it might help to explain it in very straightforward terms. If you have a variable that you don't use, for example a function for which you've commented out the invocation (a common use-case):
myFn := func () { }
// myFn()
You can assign a useless/blank variable to the function so that it's no longer unused:
myFn := func () { }
_ = myFn
// myFn()
Since VSCode v.1.24 and TypeScript v.2.9:

There actually doesn't seem to be a lot of explanation on this subject apparently but the exit codes are supposed to be used to give an indication on how the thread exited, 0
tends to mean that it exited safely whilst anything else tends to mean it didn't exit as expected. But then this exit code can be set in code by yourself to completely overlook this.
The closest link I could find to be useful for more information is this
Quote from above link:
What ever the method of exiting, the integer that you return from your process or thread must be values from 0-255(8bits). A zero value indicates success, while a non zero value indicates failure. Although, you can attempt to return any integer value as an exit code, only the lowest byte of the integer is returned from your process or thread as part of an exit code. The higher order bytes are used by the operating system to convey special information about the process. The exit code is very useful in batch/shell programs which conditionally execute other programs depending on the success or failure of one.
From the Documentation for GetEXitCodeThread
Important The GetExitCodeThread function returns a valid error code defined by the application only after the thread terminates. Therefore, an application should not use STILL_ACTIVE (259) as an error code. If a thread returns STILL_ACTIVE (259) as an error code, applications that test for this value could interpret it to mean that the thread is still running and continue to test for the completion of the thread after the thread has terminated, which could put the application into an infinite loop.
My understanding of all this is that the exit code doesn't matter all that much if you are using threads within your own application for your own application. The exception to this is possibly if you are running a couple of threads at the same time that have a dependency on each other. If there is a requirement for an outside source to read this error code, then you can set it to let other applications know the status of your thread.
You may use NULL
instead of NA
. This creates a truly empty data frame.
if ls /some/dir/* >/dev/null 2>&1 ; then echo "huzzah"; fi;
You can create a MemoryStream from a String and use that in any third-party function that requires a stream. In this case, MemoryStream, with the help of UTF8.GetBytes, provides the functionality of Java's StringStream.
String content = "stuff";
using (MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(content)))
{
Print(stream); //or whatever action you need to perform with the stream
stream.Seek(0, SeekOrigin.Begin); //If you need to use the same stream again, don't forget to reset it.
UseAgain(stream);
}
stream.Seek(0, SeekOrigin.Begin);
string s;
using (var readr = new StreamReader(stream))
{
s = readr.ReadToEnd();
}
//and don't forget to dispose the stream if you created it
If you have a QMainWindow
you can override closeEvent
method.
#include <QCloseEvent>
void MainWindow::closeEvent (QCloseEvent *event)
{
QMessageBox::StandardButton resBtn = QMessageBox::question( this, APP_NAME,
tr("Are you sure?\n"),
QMessageBox::Cancel | QMessageBox::No | QMessageBox::Yes,
QMessageBox::Yes);
if (resBtn != QMessageBox::Yes) {
event->ignore();
} else {
event->accept();
}
}
If you're subclassing a QDialog
, the closeEvent
will not be called and so you have to override reject()
:
void MyDialog::reject()
{
QMessageBox::StandardButton resBtn = QMessageBox::Yes;
if (changes) {
resBtn = QMessageBox::question( this, APP_NAME,
tr("Are you sure?\n"),
QMessageBox::Cancel | QMessageBox::No | QMessageBox::Yes,
QMessageBox::Yes);
}
if (resBtn == QMessageBox::Yes) {
QDialog::reject();
}
}
Now there is a very useful npm package for this: buffer
https://github.com/feross/buffer
It tries to provide an API that is 100% identical to node's Buffer API and allow:
and few more.
You can try this to get your combination:
as.numeric(rbind(test$x, test$y))
which will return:
26, 34, 21, 29, 20, 28
You could also use the iframe method, although this is not cross browser compatible (eg. not working in chromium or android and probably others -> instead prompts to download). It works with dataURL's and normal URLS, not sure if the other examples work with dataURLS (please let me know if the other examples work with dataURLS?)
<iframe class="page-icon preview-pane" frameborder="0" height="352" width="396" src="data:application/pdf;base64, ..DATAURLHERE!... "></iframe>
Clearing all Breakpoints fixed the issue
(within debugger perspective: Window -> Remove All Breakpoints
).
Rebuilding the project did not work for me.
Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%"
- but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.
It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.
To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%"
.
Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.
I say that doing a WHERE field LIKE "%value%"
is slower than WHERE field LIKE "value%"
if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:
1/ If you do SELECT field FROM table WHERE field LIKE "%value%"
, MySQL will scan the entire table, and only send the fields containing "value".
2/ If you do SELECT field FROM table
and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.
Solution: Please do use the WHERE
clause, and use EXPLAIN
to see the performance.
The method has been renamed to findById(…)
returning an Optional
so that you have to handle absence yourself:
Optional<Foo> result = repository.findById(…);
result.ifPresent(it -> …); // do something with the value if present
result.map(it -> …); // map the value if present
Foo foo = result.orElse(null); // if you want to continue just like before
Now with Android Studio and Gradle, you can have multiple resource folders in your project. Allowing to organize not only your layout files but any kind of resources.
It's not exactly a sub-folder, but may separte parts of your application.
The configuration is like this:
sourceSets {
main {
res.srcDirs = ['src/main/res', 'src/main/res2']
}
}
Check the documentation.
"Sleep" state connections are most often created by code that maintains persistent connections to the database.
This could include either connection pools created by application frameworks, or client-side database administration tools.
As mentioned above in the comments, there is really no reason to worry about these connections... unless of course you have no idea where the connection is coming from.
(CAVEAT: If you had a long list of these kinds of connections, there might be a danger of running out of simultaneous connections.)
Open you WAMP panel and open MySQL configuration file. In it search for "sql_mode" if you find it set it to "" else if you don't find it add sql_mode="" to the file.
Restart the MySQL server and you are good to go...
happy coding.
Try the above which will run with any list type.
public DataTable ListToDataTable<T>(IList<T> data)
{
PropertyDescriptorCollection props =
TypeDescriptor.GetProperties(typeof(T));
DataTable table = new DataTable();
for (int i = 0; i < props.Count; i++)
{
PropertyDescriptor prop = props[i];
table.Columns.Add(prop.Name, prop.PropertyType);
}
object[] values = new object[props.Count];
foreach (T item in data)
{
for (int i = 0; i < values.Length; i++)
{
values[i] = props[i].GetValue(item);
}
table.Rows.Add(values);
}
return table;
}
Go to http://localhost/phpmyadmin and click on the Privileges tab. There is a "Add a new user" link.
The only option I have found to do this is find some exact wording and put that under the "Has the words" option. Its not the best option, but it works.
Another solution is to build an associative array with date format and then reformat data.
This method is useful for date formatted in an unussual way.
An example:
mydate='01.02.12 10:20:43':
myformat='dd/mm/yy HH:MM:ss';
dtsplit=mydate.split(/[\/ .:]/);
dfsplit=myformat.split(/[\/ .:]/);
// creates assoc array for date
df = new Array();
for(dc=0;dc<6;dc++) {
df[dfsplit[dc]]=dtsplit[dc];
}
// uses assc array for standard mysql format
dstring[r] = '20'+df['yy']+'-'+df['mm']+'-'+df['dd'];
dstring[r] += ' '+df['HH']+':'+df['MM']+':'+df['ss'];
Idle Timeout is if no action has been asked from your web app, it the process will drop and release everything from memory
Recycle is a forced action on the application where your processed is closed and started again, for memory leaking purposes and system health
The negative impact of both is usually the use of your Session and Application state is lost if you mess with Recycle to a faster time.(logged in users etc will be logged out, if they where about to "check out" all would have been lost" that's why recycle is at such a large time out value, idle timeout doesn't matter because nobody is logged in anyway and figure 20 minutes an no action they are not still "shopping"
The positive would be get rid of the idle time out as your website will respond faster on its "first" response if its not a highly active site where a user would have to wait for it to load if you have 1 user every 20 minutes lets say. So a website that get his less then 1 time in 20 minutes actually you would want to increase this value as the website has to load up again from scratch for each user. but if you set this to 0 over a long time, any memory leaks in code could over a certain amount of time, entirely take over the server.
I wanted the real deal, so I add UIImageView
as a subview of the UITextView
. This matches the native border on a UITextField
, including the gradient from top to bottom:
textView.backgroundColor = [UIColor clearColor];
UIImageView *borderView = [[UIImageView alloc] initWithFrame: CGRectMake(0, 0, textView.frame.size.width, textView.frame.size.height)];
borderView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
UIImage *textFieldImage = [[UIImage imageNamed:@"TextField.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(15, 8, 15, 8)];
borderView.image = textFieldImage;
[textField addSubview: borderView];
[textField sendSubviewToBack: borderView];
These are the images I use:
While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event
argument to the setMaster
function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):
function AdminController($scope) {
$scope.setMaster = function(obj, $event){
console.log($event.target);
}
}
this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.
The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event
argument) would be:
<div ng-controller="AdminController">
<ul class="list-holder">
<li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
<a ng-click="setMaster(section)">{{section.name}}</a>
</li>
</ul>
<hr>
{{selected | json}}
</div>
where methods in the controller would look like this:
$scope.setMaster = function(section) {

Fetching data with either null and value on where conditions are very tricky. Even if you are using straight Where and OrWhereNotNull condition then for every rows you will fetch both items ignoring other where conditions if applied. For example if you have more where conditions it will mask out those and still return with either null or value items because you used orWhere condition
The best way so far I found is as follows. This works as where (whereIn Or WhereNotNull)
Code::where(function ($query) {
$query->where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id');
})->get();
If you look at the Console
class in .NET Reflector, you'll find that if a process doesn't have an associated console, Console.Out
and Console.Error
are backed by Stream.Null
(wrapped inside a TextWriter
), which is a dummy implementation of Stream
that basically ignores all input, and gives no output.
So it is conceptually equivalent to /dev/null
, but the implementation is more streamlined: there's no actual I/O taking place with the null device.
Also, apart from calling SetOut
, there is no way to configure the default.
Update 2020-11-02: As this answer is still gathering votes in 2020, it should probably be noted that under ASP.NET Core, there usually is a console attached. You can configure the ASP.NET Core IIS Module to redirect all stdout and stderr output to a log file via the stdoutLogEnabled
and stdoutLogFile
settings:
<system.webServer>
<aspNetCore processPath="dotnet"
arguments=".\MyApp.dll"
hostingModel="inprocess"
stdoutLogEnabled="true"
stdoutLogFile=".\logs\stdout" />
<system.webServer>
Create a class called Round and try using the method round as Round.round(targetValue, roundToDecimalPlaces) in your code
public class Round {
public static float round(float targetValue, int roundToDecimalPlaces ){
int valueInTwoDecimalPlaces = (int) (targetValue * Math.pow(10, roundToDecimalPlaces));
return (float) (valueInTwoDecimalPlaces / Math.pow(10, roundToDecimalPlaces));
}
}
Run it in parallel with

From the Python glossary:
It’s important to keep in mind that all packages are modules, but not all modules are packages. Or put another way, packages are just a special kind of module. Specifically, any module that contains a
__path__
attribute is considered a package.
Python files with a dash in the name, like my-file.py
, cannot be imported with a simple import
statement. Code-wise, import my-file
is the same as import my - file
which will raise an exception. Such files are better characterized as scripts whereas importable files are modules.
As @jeff-dickey suggested, in the root of your project, make a folder called test
. In that folder, make a file called mocha.opts
. Now where I try to improve on Jeff's answer, what worked for me was instead of specifying the name of just one test folder, I specified a pattern to find all tests to run in my project by adding this line:
*/tests/*.js --recursive
in mocha.opts
If you instead want to specify the exact folders to look for tests in, I did something like this:
shared/tests/*.js --recursive
server/tests/graph/*.js --recursive
I hope this helps anyone who needed more than what the other answers provide
you can use ps
.
e.g. having python process with two busy threads on dual core CPU:
$ ps -p 29492 -L -o pid,tid,psr,pcpu
PID TID PSR %CPU
29492 29492 1 0.0
29492 29493 1 48.7
29492 29494 1 51.9
(PSR is CPU id the thread is currently assigned to)
you see that the threads are running on the same cpu core (because of GIL)
running the same python script in jython, we see, that the script is utilizing both cores (and there are many other service or whatever threads, which are almost idle):
$ ps -p 28671 -L -o pid,tid,psr,pcpu
PID TID PSR %CPU
28671 28671 1 0.0
28671 28672 0 4.4
28671 28673 0 0.6
28671 28674 0 0.5
28671 28675 0 2.3
28671 28676 0 0.0
28671 28677 1 0.0
28671 28678 1 0.0
28671 28679 0 4.6
28671 28680 0 4.4
28671 28681 1 0.0
28671 28682 1 0.0
28671 28721 1 0.0
28671 28729 0 88.6
28671 28730 1 88.5
you can process the output and calculate the total CPU for each CPU core.
Unfortunately, this approach does not seem to be 100% reliable, sometimes i see that in the first case, the two working threads are reported to be separated to each CPU core, or in the latter case, the two threads are reported to be on the same core..
Build solution will build any projects in the solution that have changed. Rebuild builds all projects no matter what, clean solution removes all temporary files ensuring that the next build is complete.
In terms of ?#/Java, function is the block of code, which return particular value, but procedure is the block of code which return void (nothing). In C#/Java both functions and procedures more often called just methods.
//This is a function
public DateTime GetCurrentDate()
{
return DateTime.Now.Date;
}
//This is a procedure(always return void)
public void LogMessage()
{
Console.WriteLine("Just an example message.");
}
Please review the following documentation. It will definitely solve the problem. http://www.programmersought.com/article/55001874709/
You could fire an event into the quit() slot of your application even without connect(). This way, the event-loop does at least one turn and should process the events within your main()-logic:
#include <QCoreApplication>
#include <QTimer>
int main(int argc, char *argv[])
{
QCoreApplication app( argc, argv );
// do your thing, once
QTimer::singleShot( 0, &app, &QCoreApplication::quit );
return app.exec();
}
Don't forget to place CONFIG += console
in your .pro-file, or set consoleApplication: true
in your .qbs Project.CppApplication.
In case some wonders how to do it using Scala (using Spark 2.0.+), here you go:
scala> df.createOrReplaceTempView("TEMP_DF")
scala> val myMax = spark.sql("SELECT MAX(x) as maxval FROM TEMP_DF").
collect()(0).getInt(0)
scala> print(myMax)

jQuery would allow you to do that.
Look up the click()
function:
http://api.jquery.com/click/
Example:
$('#yourDIV').click(function() {
alert('You clicked the DIV.');
});
function isValidEmailAddress(emailAddress) {
var pattern = /^([a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+(\.[a-z\d!#$%&'*+\-\/=?^_`{|}~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+)*|"((([ \t]*\r\n)?[ \t]+)?([\x01-\x08\x0b\x0c\x0e-\x1f\x7f\x21\x23-\x5b\x5d-\x7e\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|\\[\x01-\x09\x0b\x0c\x0d-\x7f\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))*(([ \t]*\r\n)?[ \t]+)?")@(([a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\d\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.)+([a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF][a-z\d\-._~\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]*[a-z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])\.?$/i;
return pattern.test(emailAddress);
}
if( !isValidEmailAddress( emailaddress ) ) { /* do stuff here */ }
The code below solved my problem.
material.MaterialCasualties = material.MaterialCasualties.Append(materialCasualties).ToList();
OR
customCustomer.CustomCustomerPayments = customCustomer.CustomCustomerPayments.Concat(customCustomerPayment).ToList();
It's a general comparison operator. It returns either a -1, 0, or +1 depending on whether its receiver is less than, equal to, or greater than its argument.
TempData
is a bucket where you can dump data that is only needed for the following request. That is, anything you put into TempData is discarded after the next request completes. This is useful for one-time messages, such as form validation errors. The important thing to take note of here is that this applies to the next request in the session, so that request can potentially happen in a different browser window or tab.
To answer your specific question: there's no right way to use it. It's all up to usability and convenience. If it works, makes sense and others are understanding it relatively easy, it's good. In your particular case, the passing of a parameter this way is fine, but it's strange that you need to do that (code smell?). I'd rather keep a value like this in resources (if it's a resource) or in the database (if it's a persistent value). From your usage, it seems like a resource, since you're using it for the page title.
Hope this helps.

Regarding tables names, case, etc, the prevalent convention is:
UPPER CASE
lower_case_with_underscores
UPDATE my_table SET name = 5;
This is not written in stone, but the bit about identifiers in lower case is highly recommended, IMO. Postgresql treats identifiers case insensitively when not quoted (it actually folds them to lowercase internally), and case sensitively when quoted; many people are not aware of this idiosyncrasy. Using always lowercase you are safe. Anyway, it's acceptable to use camelCase
or PascalCase
(or UPPER_CASE
), as long as you are consistent: either quote identifiers always or never (and this includes the schema creation!).
I am not aware of many more conventions or style guides. Surrogate keys are normally made from a sequence (usually with the serial
macro), it would be convenient to stick to that naming for those sequences if you create them by hand (tablename_colname_seq
).
See also some discussion here, here and (for general SQL) here, all with several related links.
Note: Postgresql 10 introduced identity
columns as an SQL-compliant replacement for serial.
According to Flexbugs:
In IE 10-11,
min-height
declarations on flex containers work to size the containers themselves, but their flex item children do not seem to know the size of their parents. They act as if no height has been set at all.
Here are a couple of workarounds:
<aside>
and <section>

height: 100%;
}
body {
display: flex;
flex-direction: column;
height: 100%;
margin: 0;
}

}
main {
flex: 1;
display: flex;
}
aside, section {

Angularjs already has filter option to do this , https://docs.angularjs.org/api/ng/filter/filter
This works in all chrome, IE, Firefox.
In Database > table > field type .for example set the symbol column TO varchar(2) utf8_bin
php code:
$symbol = '£';
echo mb_convert_encoding($symbol, 'UTF-8', 'HTML-ENTITIES');
or
html_entity_decode($symbol, ENT_NOQUOTES, 'UTF-8');
And also make sure set the HTML OR XML encoding to encoding="UTF-8"
Note: You should make sure that database, document type and php code all have a same encoding
How ever the better solution would be using £
